The shackle 40 has a first and second leg, one of which is longer than the other. The shackle recesses 41, 42 receive the first and second legs of a generally U-shaped shackle 40. Each shackle recess 41, 42 includes a ring seal so that when the shackle is moving from an extended position to a retracted position or vice versa, the ring seal prevents water from getting into the front cover 9. In one embodiment, the ring seal is an O-ring or any other suitable seal. The input interface 35 allows a user to depress a passcode indicated by a series of pre-set numbers to operate a locking mechanism within the electronic lock 100, to allow axial movement of the shackle 40 from a retracted position to an extended position, such that the short leg of the shackle 40 may be disengaged or withdrawn from the lock body 50 to open the electronic lock 100. In one embodiment, the front cover 9 also has an indicator display 91, and the electronic lock has a controller that connects to a power source 21. The power source includes but is not limited to rechargeable battery, a battery, fuel cells, energy harvesters or other suitable power sources. The controller has a display light that corresponds with the indcator display hole 91. The indicator display 91 shows the power source's status, such as low power or drained. This helps the user know how much power source is left and to change it when needed. It also prevents the user from thinking the electronic lock is broken when the power source runs out of power.

[0081] FIG. 2 illustrates an exploded perspective view of an electronic lock and its internal components. Referring to FIG. 2, and for the purpose of illustration, the electronic lock 100 has its rear cover 10 removed to reveal its internal components. The electronic lock 100 includes a power source assembly comprising a frame 1, a power source enclosure 2 for enclosing a power source 21, a compartment pad 3 and a compartment cover 4. The frame 1 includes a compartment 11 that is configured for receiving the replaceable power source 2 and includes one or more connectors in the frame 1 for connecting the power source 2 to the locking mechanism. The compartment pad 3 is configured to seal the frame 1 once the power source 2 has been installed in the frame. The compartment cover 4 is placed on top of the compartment pad 3. The compartment pad 3 and the compartment cover 4 includes mutually aligned holes that facilitate the placement of compartment cover 4 over compartment pad 3 in order to secure compartment cover 4 on compartment pad 3.

[0082] FIG. 3 illustrates a perspective view of the power source assembly according to various embodiments. The frame 1 includes a base a base having four walls 12 extending upwardly from the base to define a compartment or a cavity for receiving a replaceable power source. Each wall 12 has a top edge and a bottom edge and the bottom edge is connected to one of the sides of the base, and the top edge includes a recess or a groove that extends longitudinally along the top edge so that the recess extends along the perimeter of the top edge of the frame. The walls 12 are connected in sequence to form a shape. The shape, can for example, be a square or any other desired shape. Each wall 12 has a top edge, and within the top edge of each wall, a recess 13 surrounds the perimeter of the top edge of the frame 1. The power source enclsoure 2 is removable from the compartment 11. The compartment pad 3 has bottom surface that includes a boss 31 that fits snugly with the groove 13 by inteference fit. In some embodiments, the compartment pad 3 is made of silicone material. The frame 1 includes apertures 5 located around the perimeter. The apertures 5 are protruding outwards from the frame 1 and extends along the height of the frame 1. The apertures 5 are aligned mutually with apertures 5 of the connecting parts, for example, the compartment pad 3 and the compartment cover 4 for the purpose of securing the connecting parts to the frame 1. The apertures 5 of the frame 1 and the apertures 5 of the connecting parts are configured to receive connectors, for example, screws to secure them together. When in use and whenever the power source needs to be replaced, the connectors, the compartment cover 4, and the compartment pad 3 can be taken off in respective order, exposing the power source enclosure 2. The power source enclosure 2 is subsequently removed from the compartment 11 and replaced with a new power source enclosure 2 storing a new power source 21 of the same model. Finally, the compartment pad 3, the compartment cover 4, and the connectors can be put back in place. Because the boss of the compartment pad 3 and the groove 13 of the power source compartment 11 are secured by interference fit, the power source 2 can be securely fixed to the electronic lock. The interference fit between the compartment pad 3 and the frame 1 also provides the power source enclosure 2 with excellent waterproofing properties, preventing the power source from water ingress and avoiding the power source from short circuiting. The compartment cover 4 is securely fitted on the compartment pad 3 and the frame 1 which reduces the risk of damage to the power source 21.

The lock body 50 includes a front cover 9 and a rear cover 10 that is removably detachable from the front cover 9. The shackle 40 is designed to latch and unlatch relative to the lock body 50, enabling locking and unlocking.

[0090] FIG. 13 illustrates a perspective view of the internal components of an electronic lock without its front cover and rear cover according to various embodiments. A cavity resides within the front cover 9 and the rear cover 10. The cavity includes a central frame 3 and an input interface frame 15. The input interface frame 15 includes a recess 31. The input interface frame 15 is configured to receive a keypad plate that includes alphanumeric symbols 42 for users to depress. The input interface frame 15 has an upper surface that surrounds the frame and include a channel surrounding the input interface frame 15. In one embodiment, the input interface frame 15 includes a PCB board (not shown) in the recess 31. The recess 31 includes a cable opening 33 and a speaker opening 34 on its surface. The speaker on the PCB board faces the speaker opening 34, which has a waterproof membrane over it (not shown). The cable opening 33 is configured for receiving a cable from the power source enclosure 2 and is sealed with waterproof glue around the cable. The cable carries current and signals to the drive motor, and it connects the PCB board and the drive motor. In this way, the electronic lock ensures good electrical and sound functions, and prevents water from entering through the cable opening 33 or the speaker opening 34, improving its water resistance.

[0091] FIG. 14 illustrates a perspective view of a keypad plate according to various embodiments. The keypad plate 4 includes alphanumeric symbols 42 for users to depress. The keypad plate 4 is made of a flexible material like rubber or silicone and is configured to be received by the input interface controller (not shown, explained later).

The bottom surface of the keypad plate 4 includes a first protrusion 41 that matches the shape of the channel 32 of the input interface frame 15. The protrusion 41 is configured to fit tightly into the channel 32 to ensure that the keypad plate 4 and the input interface frame 15 is sealed. In some embodiments, the protrusion 41 has a lip shape to make the fit stronger. This way, the protrusion 41 of the key plate 4 and the channel 32 of the central frame 3 seals the cavity within the front cover and the rear cover and prevents ingress of water. The cavity is also configured to store the power source, controller, drive motor, and other electronic parts directly or indirectly. This means the cavity protects the electronic parts from water and prevents short circuits. This helps the electronic lock last longer, work better, and be used in different places. In some embodiments, the bottom surface of the keypad plate 4 includes a plurality of grooves surrounding the perimeter of the alphanumeric symbols or along the edge of the keypad plate 4. For example, the plurality of grooves include a pair of wave grooves 411, a pair of arc grooves 412, and a moment groove 413. Each of the aforesaid grooves has a different shape resulting in different elastic deformation when fitted with the channel 32 of the input interface frame 15, leading to a firmer fit with the channel 32 and improved waterproofing property.

[0093] Referring to FIGS. 14 and 15, the keypad plate 4 has two opposing surfaces: the top plate surface and the bottom plate surface. The bottom plate surface has a protrusion 41, and the top plate surface has a plurality of key bosses 42. Each key boss 42 includes a column 43 below its top surface that is visible from the bottom plate surface. When the columns 43 are not pressed, their free ends are lower than the free ends of the protrusion 41 in the direction of the bottom plate surface. This gives each column 43 some space to move perpendicularly to the bottom plate surface. This makes the lock waterproof and comfortable to use when the user presses the key bosses 42.

[0094] FIG. 16 illustrates a perspective view of the key plate according to various embodiments. In one embodiment, the key plate 4 has many openings 70 that fit the key bosses 42.

The top plate surface of the key plate 4 has a raised platform 44 surrounding the alphanumeric keys that squeeze into the notches 12 and touch the waterproof ribs 13. By putting waterproof glue (not shown) between the raised platforms 44 and the notches 12, the lock becomes more waterproof and stops water from getting inside the key plate 4.

[0095] FIG. 17 illustrates a side view of an electronic lock without its front cover according to various embodiments. FIG. 18 shows a waterproof plate according to various embodiments. Referring to the aforesaid figures, the central frame 3 includes a charging port 35, which includes a USB Type-C interface 5 on the PCB board. A waterproof plate 6 is configured for mounting to the bottom end of the central frame 3. The waterproof plate 6 includes two openings 63, each configured to receive a screw for mounting to the central frame 3. The waterproof plate 6 has a bump 61 that touches the edge of the Type-C interface 5, and a hole 62 corresponding to the charging port 35 and the Type-C interface 5. The gap between the bump 61 and the Type-C interface 5 is filled with waterproof glue, which can be injected by a syringe-like device. An elastic ring 7 is fixed on the central frame 3, and the bump 61 presses against it. In this way, the waterproof plate 6 improves the water resistance of the Type-C interface 5, which is usually vulnerable to water.

[0096] FIG. 19 illustrates a side view of the electronic lock according to various embodiments. FIG. 20 illustrates a sealing plug for the electronic lock according to various embodiments. In one embodiment, a sealing plug 8 is configured for mounting onto the Type-C interface 5. The sealing plug 8 is made of silicone, and it has a cover 81 with a movable rod 82 and a plug 83 on the side facing the Type-C interface 5. The movable rod 82 has a rod 821 and two bumps 822 that prevents the plug 8 from falling off the electronic lock. The rod 821 goes into a socket 78 at the bottom end of the front cover 9, and the bumps 822 squeeze through the socket 78, keeping the plug 8 attached to the front cover 9. The plug 83 has a hole 831 that matches the Type-C interface 5, and the cover 81 fits into a recess portion on the front cover 9. When the Type-C interface 5 is not in use, the cover 81 of the plug 8 covers the recess portion, and the plug 83 blocks the Type-C interface 5, stopping water from entering the electronic lock. There are also several pairs of holes 79 on the recess portion and the cover 81, which let any water that gets inside the front cover 9 drain out by gravity, preventing it from building up.

[0097] FIG. 21 is a perspective view of a compartment pad 3 according to various embodiments. FIG. 22 is a perspective view of a compartment cover 4 according to various embodiments. As mentioned previously and with reference to FIG. 21, in one embodiment, the compartment pad 3 has a bottom surface that includes the boss 31 extending around the perimeter of the compartment pad 3. The boss 31 fits snugly with the groove 13 of the frame 1 by inteference fit. The compartment pad 3 is rectangular in shape and follows the shape of the frame 1. At certain sections of the compartment pad 3, one or more protrusions extend outwardly from the compartment pad 3. The protrusions include apertures 5 that are mutually aligned with the respective apertures of the frame 1 and the compartment cover 4. In one embodiment, the protrusion includes a protrusion 32 to allow the user to easily pull off the compartment pad 3 from the frame 1 when replacing the power source enclosure 2. In some embodiments, the compartment pad 3 is made of silicone material.

[0098] Referring to FIG. 22, the compartment cover 4 is configured for mounting on top of the compartment pad 3. The compartment cover 4 includes more than two apertures protruding outwards from the compartment cover 4. In one embodiment, the compartment pad 3 has an upper surface that includes sealing ribs (not shown) configured to improve the sealing between the compartment cover 4 and the compartment pad 3 when the compartment cover 4 is pressed against the compartment pad 3. In some embodiments, the compartment cover 4 is made of plastic. This ensures the power source works well and lowers the chance of the electronic lock breaking because of a short circuit in the power source. [0046] In one embodiment, the compartment cover 4 has two or more elastic ribs 75. When the compartment cover 4 is attached to the compartment pad 3, the two rings of elastic ribs 75 squeeze and changes shape to make the connection between the compartment pad 3 and the bon cover 4 tighter and more stable. Also, the mutually aligned apertures 5 on the walls 12 of the frame 1, compartment pad 3 and compartment cover 4 forms a sharp triangle making the compartment cover 4 press evenly on the elastic ribs 75. This ensures the power source works well and lowers the chance of the electronic lock breaking because of a short circuit in the power source.

[0099] FIG. 23 illustrates a motor cover according to various embodiments. The electronic lock 100 includes a drive motor (not shown) and a motor cover IF, which can be made of stainless steel. When the electronic lock is a padlock, the drive motor can move the lock cylinder to lock or unlock with the shackle. The motor cover IF has an output hole and an input hole. The output shaft 1E1 of the drive motor comes out of the output hole, and there is a sealing ring (not shown) between the opening and the output shaft 1E1. The motor wire 1E2 of the drive motor goes out of the input hole, and the part of the motor wire 1E2 that touches the motor cover IF is sealed with waterproof glue. In this way, the drive motor can work in a closed space, and it can still run well for a long time even if the area around the motor cover IF is under water.

[0100] The present invention therefore provides various embodiments and combinations of a power source assembly and an electronic lock that faciliates easy power source replacement. The design of the related structure also enables the power source of the electronic lock to have a great waterproof seal which in turn leads to a longer lifespan and higher reliability of the electronic lock.

[0101] While addressing the issues of easy power source replacement and waterproofing of the electronic lock during its use, it is also noted that storage and transportation methods of electronic locks can significantly impact their subsequent usage and lifespan. Currently, there are two common transportation methods. The first involves disassembling the power source from the electronic lock for transport, then reinstalling it when the user is ready to use the electronic lock. The second method involves transporting the smart lock in a low-power mode, ready to be activated into normal working mode at any time.

[0102] However, both methods have significant drawbacks. In the first method, the power source is stored separately from the smart lock during transport, making it susceptible to damage. Additionally, improper installation by the user can cause accidental damage to the control circuit and the power source within the smart lock's body, and potentially compromise the lock's sealing function. In the second method, issues such as packaging pressure and manual handling errors during transport can inadvertently end the lock's low-power mode, causing it to enter normal working mode prematurely. This can result in the smart lock reaching the user with a depleted power source or unnecessary power source consumption, thereby shortening its subsequent service life.

[0103] The present invention intends to address the aforesaid problems, and provides a method and system of controlling an electronic lock. The term electronic lock is broadly intended to include any type of lockset that uses electrical power in some manner, including but not limited to electronic deadbolts, electronic lever sets, electronic door locksets, and padlocks.

[0104] FIG. 24 illustrates a flow chart of a method of controlling an electronic lock according to various embodiments. The method includes the following steps:

[0105] S1: Determine if a time duration of power source installation in the lock body meets a predetermined installation time duration (J), wherein if the time duration of power source installation meets the predetermined installation time duration, the electronic lock enters an ultra-low power mode and proceeds to step S2. If not, the system resets and returns to S1.

[0106] S2: Determine if a number of activations and deactivations of the electronic lock in the ultra-low power mode meets a predetermined number of times, wherein if the predetermined number of times are met, the electronic lock enters a wake up mode. In some embodiments, the activations and deactivations of the electronic lock are associated with the locking and unlocking functions, and in one embodiment, the activation is associated with the latching of the shackle for locking and the deactivation is associated with the unlatching of the shackle for unlocking. The number of activations and deactivations denote the total number of times (K) the shackle has been detected to have latched and unlatched from the lock body. In some embodiments, the total number of times K can be predetermined as desired, and can be from 3 times. In another embodiment, the activations and deactivations of the electronic lock are associated with the charging of the power source via the charging interface on the electronic lock. For example, the activation is associated with plugging a charging cable into the charging interface, and the deactivation is associated with unplugging of the charging cable from the charging interface. The number of activations and deactivations denote the total number of times (L) the charging cable is detected to have been plugged and unplugged from the Charging interface. When the number of activations and deactivations of the electronic lock has met a predetermined number, the electronic lock enters a wake-up mode. If not, the electronic lock remains in the ultra-low power mode.

[0107] S3: In the wake-up mode, the controller determines if a pairing operation for the electronic lock is completed within the predetermined time duration (M). If it is, the electronic lock enters a normal working mode. If not, the electronic lock reverts to the ultra-low power mode.

[0108] Here, J, K, L, M are positive numbers. Generally, the power consumption ratio of ultra-low power mode, wake-up mode, and normal working mode is preferably set to 0.2:0.6:1.5. This ratio is derived from empirical values obtained from the usage of numerous electronic locks. It effectively reduces power loss in smart lock circuit devices and extends the service life of smart locks.

[0109] Therefore, this method for controlling the electronic lock ensures that the electronic lock does not suffer accidental damage during storage and transportation, and prevents accidental wake-ups, reducing unnecessary power source consumption. Simultaneously, based on a pre-installed power source, the ultra-low power mode is set. This eliminates the need for the user to install the power source on the smart lock themselves, reducing potential damage to the smart lock during power source installation and improving power source energy consumption efficiency.

[0110] In some embodiments, the electronic lock includes a lock body, a locking mechanism for latching and unlatching for locking and unlocking respectively, a power source, a charging interface for charging the power source, and a controller in communication with the locking mechanism, power source and charging interface.

[0111] In one embodiment, the electronic lock 100 includes a lock body having a first shackle recess 41 and a second shackle recess 42 extending from an upper end of the lock body 50. The electronic lock has a shackle 40 that includes a first and second leg, one of which is longer than the other. The shackle recesses 41, 42 receive the first and second legs of a generally U-shaped shackle 40.

[0112] FIG. 25 illustrates a flow chart of a method of controlling the electronic lock via a magnetic sensor. In one embodiment, the shackle includes a magnet positioned on the shackle. For example, the magnet can be positioned on an end of the shorter leg of the shackle. A magnetic sensor is also located within the lock body. A detection module, details of which is explained later, is in electrical communication with the magnetic sensor for determining the number of changes in magnetic inductance intensity. When the shackle moves in relation to the lock body during the latching and unlatching process, it drives the magnet to move closer to or further from the lock body. By arranging a magnet on the shackle, and having the magnet move closer to or further from the magnetic sensor with the shackle's movements, the magnetic sensor can accurately determine the number of times the shackle has moved in relation to the lock body. This is based on the number of changes in the sensed magnetic induction intensity.

[0113] Referring to FIG. 25, the detection module determines if the number of changes in magnetic induction intensity sensed by the magnetic sensor due to the latching and unlatching of the shackle relative to the lock body meets a predetermined number of times. If the predetermined number of times is met, the electronic lock enters a wake up mode. If not, the electronic lock remains in the ultra-low power mode. In some embodiments, the controller receives the number of latching and unlatching movements of the shackle relative to the lock body has reached the predetermined number of times K. This step further includes the detection module determining whether the number of changes in magnetic inductance intensity sensed by the magnetic sensor due to the magnet's movement has reached the predetermined number of times K. This method ensures that the control method for the smart lock is highly accurate and sensitive.

[0114] FIG. 26 illustrates a flow chart of a method of controlling an electronic lock via the charging interface. An external charging plug or cable could be connected to a flash drive or a power bank, for instance. An external source receiver, capable of receiving signals and/or power, receives a signal source or power source from a USB flash drive or power bank as an external source. Therefore, an external charging plug is used to connect to the charging interface and can be plugged and unplugged multiple times, offering more convenience and speed. In one embodiment, the electronic lock can simultaneously determine the two types of plugging and unplugging times and control it accordingly. Referring to FIG. 26, the detection module in electrical communication with the charging interface determines if the number of pluggings and unpluggings from the charging interface sensed by the detection module meets a predetermined number of times. If the predetermined number of times is met, the electronic lock enters a wake up mode. If not, the electronic lock remains in the ultra-low power mode.

[0115] In one embodiment, the lock body is equipped with an input interface including a purality of buttons. In one embodiment, the plurality of buttons includes several numeric keys and is located on a key circuit board. A pairing operation includes registration operation including key registration, web page registration, and mobile phone APP registration, or connecting to the electronic lock via a wireless communication. As a result, the user has various pairing methods to operate and register the smart lock, making the operation convenient and flexible.

[0116] For further specific implementation, J, K, L, and M are set to 1 minute, 3 times, 3 times, and 1 minute, respectively. Through the inventor's repeated experiments and big data analysis, J, K, L, and M are set as the specific values mentioned above. This not only conforms to the actual operation characteristics of users but also avoids misjudgments and misjudgments of related judgments.

[0117] The embodiment initially controls the electronic lock to run in ultra-low power mode when it is determined that the power source has been normally installed in the lock body. It then determines the number of activations and deactivations of the electronic lock via the latching and unlatching movements of the shackle relative to the lock body or the plugging and unplugging of an external charging plug and from the charging interface. The determination of the number of activations and deactivations, if it meets a predetermined number, enables the lock to enter the wake-up mode, and if it does not meet the predetermined number, the electronic lock continues to run the ultra-low power mode. Finally, the pairing operation of the electronic lock is determined to be completed within a certain period of time, and if it does not meet the predetermined time duration, the electronic lock continues to run the ultra-low power consumption mode. As a result, it ensures that the electronic lock is protected from accidental damage and unnecessary consumption of the power source when stored in the warehouse or transported as goods.

[0118] FIG. 27 illustrates a block diagram of a system for controlling an electronic lock. Referring to FIG. 27, in addition to the previous embodiments, this embodiment also introduces a system for controlling an electronic lock. The electronic lock includes a lock body, a shackle, a power source, a charging interface and a controller in electrical communication with the power source and charging interface. The lock body is equipped with an charging interface, and the shackle is designed for latching and unlatching movements relative to the lock body to enable locking and unlocking.

[0119] In various embodiments, the system comprises: [0120] a controller that includes a main control chip (eg. a wireless transmitter and/or a receiver) for Bluetooth communication; [0121] a power source module which receives current from the power source and powers the main control chip; [0122] a timing module, which determines if the time duration of the power source installation in the lock body meets or exceeds the predetermined time duration J; [0123] a detection module that includes a shackle motion detection module and/or a charging interface detection module. As previously mentioned, the shackle motion detection module compares and determines the number of latching and unlatching movements of the shackle relative to the lock body via detection of magnetic induction intensity. The charging interface detection module compares and determines whether the number of pluggings and unpluggings of the external Charging plug-in relative to the charging interface reaches the predetermined number of times L. [0124] a pairing detection module, which determines the time taken to complete the pairing operation of the electronic lock and whether the time taken is less than or equal to the pretermined time duration M. [0125] an operation mode module, which controls the electronic lock to run in the ultralow power mode based on the determination of the timing module, detection module and the pairing module. It also controls the electronic lock to run in a wake-up mode and ultra-low power mode respectively based on the results of the timing module, detection module and the pairing module.

[0126] In an embodiment, a module may be understood as any kind of a logic implementing entity, which may be special purpose circuitry or a processor executing software stored in a memory, firmware, or any combination thereof. Thus, in an embodiment, a module may be a hard-wired logic circuit or a programmable logic circuit such as a programmable processor, e.g. a microprocessor (e.g. a Complex Instruction Set Computer (CISC) processor or a Reduced Instruction Set Computer (RISC) processor). A module may also be a processor executing software, e.g. any kind of computer program, e.g. a computer program using a virtual machine code such as e.g. Java. Any other kind of implementation of the respective functions which will be described in more detail below may also be understood as a circuit in accordance with an alternative embodiment.

[0127] In various embodiments, the power source module, the timing module, the detection module and the pairing detection module are each connected to the signal input terminal of the controller. The operation mode control module is connected to the signal output terminal of the controller.

[0128] The system can implement the method of controlling the electronic lock, thereby ensuring that the electronic lock does not suffer accidental damage and accidental wake-up during storage and transportation. It prevents unnecessary power source consumption and avoids the adverse effects of pressing and disassembling the power source by disassembling the machine.

[0129] In various embodiments, and as mentioned previously, the shackle is equipped with a magnet positioned in the lock body. The detection module includes a Hall switch sensor and a sensor circuit that is electrically connected with the Hall switch sensor. When the shackle performs latching and unlatching movements relative to the lock body, the magnet is driven to move closer and farther from the Hall switch sensor. The sensor circuit is electrically connected to the controller through the signal connection line. By default, the sensor circuit outputs a low level to the controller. When the magnet is close to the Hall switch sensor, the sensor circuit outputs a high level to the controller. When the magnet is far from the Hall switch sensor, the sensor circuit outputs a low level to the controller.

[0130] In various embodiments, the timing module includes a timing circuit, and the power source module contains a power supply circuit. The timing circuit combines a first vibration circuit and a second vibration circuit to provide a clock to the controller. The power supply circuit consists of a ripple filtering and energy storage circuit, an internal power supply circuit, and a reset circuit. The ripple filtering and energy storage circuit delivers the power source's power to the controller. The internal power supply circuit, located within the controller, provides an internal DC-DC power supply. The reset circuit resets the operation after the controller is powered on.

In some cases, the memory 404 is a ROM, which can be a mask-programmed ROM, a PROM, an EPROM, an EEPROM, an EAROM, a flash memory, or a combination of them.

[0132] The electronic lock also includes a communication interface 405 and a bus 410. The communication interface 405 has a Bluetooth communication interface on the main control chip. Referring to FIG. 28, a magnetic sensor 401, a charging interface 402, a processor 403, a memory 404, and a communication interface 405 are connected and communicate through the bus 410. The communication interface 405 is mainly for communication between different modules, devices, units, and/or devices in this invention. The bus 410 has hardware, software, or both that connect the parts of the smart lock. For example, buses can be AGP or other graphics buses, EISA buses, FSBs, HT interconnects, ISA buses, unlimited bandwidth interconnect, LPC bus, memory bus, MCA bus, PCI bus, PCI-X bus, SATA bus, VLB bus, or other suitable bus or a combination of them. The bus 410 can have one or more buses. The invention can use any suitable bus or interconnection, not just the one shown here.

[0133] The electronic lock includes the communication interface 405 and the bus 410. The communication interface includes a Bluetooth communication interface on the main control chip Ul. The bus 410 connects and allows communication between a magnetic sensor 401, a charging interface 402, a processor 403, a memory 404, and a communication interface 405, as shown in FIG. 28. The communication interface 405 is used for communication among various modules, devices, units, and/or devices in this invention. The bus 410 consists of hardware, software, or both that link the components of the smart lock. For example, buses can be AGP or other graphics buses, EISA buses, FSBs, HT interconnects, ISA buses, unlimited bandwidth interconnect, LPC bus, memory bus, MCA bus, PCI bus, PCI-X bus, SATA bus, VLB bus, or other appropriate bus or a combination of them. The bus 410 can be one or more buses. The invention is not limited to the bus shown here, but can use any suitable bus or interconnection.

[0134] In various embodiments, the controller is equipped with a Bluetooth module for connecting with the App on a control device (for example, a mobile device). A pairing operation includes connecting the electronic lock with the control device, and registration operations via key-button registration, web registration, and mobile app registration. The lock body includes a key circuit board that is electrically connected to the key. The pairing module includes a registration determination circuit that is electrically connected to the key circuit board. The registration determination circuit comprises a Bluetooth receiving circuit and a local input circuit. The local input circuit receives the registration information entered by the user via the key and transmits it to the controller. The Bluetooth receiving circuit receives the registration information entered by the user through the webpage or mobile phone APP via Bluetooth communication and transmits it to the controller. In one embodiment, the chip model of the main control chip is nRF52832, which can support related wireless communication protocols such as low-power Bluetooth, ANT, etc.

[0135] A variety of control devices may be employed in accordance with the invention. The control devices may include mobile devices, smart phones, smart devices, tablets, PCs, digital home clients such as personal computers and media centers, and other control devices. Generally, control device may include virtually any portable computing device capable of receiving and sending a message over a network, such as network, or the like. A control device may also be described generally as a client device that is configured to be portable. A control device may have the capability of connecting to a network using wireless technology, wired technology, or a combination of both wired and wireless technologies. Thus, a control device may include virtually any portable computing device capable of connecting to another computing device and receiving information. Such devices include portable devices such as cellular telephones, smart phones, display pagers, radio frequency (RF) devices, infrared (IR) devices, Personal Digital Assistants (PDAs), handheld computers, sensors, laptop computers, wearable computers, tablet computers, integrated devices combining one or more of the preceding devices, and the like. As such, control device typically ranges widely in terms of capabilities and features.
