[0039] As shown in FIG. 1 to FIG. 8, a door system according the embodiment of the present invention includes a door frame 710, a door leaf 720, a door lock and a door opener 730.

[0040] One side of the door frame 710 is rotatably connected with the door leaf 720 through a hinge, a bisagra or other structures, and the door lock is arranged on the other side of the door leaf 720. The door opener 730 connects the door frame 710 with the door leaf 720, and when the door opener 730 is operated, the door leaf 720 may be pushed to rotate to realize automatic door opening. The door lock includes a lock body 100, a first handle assembly 200, a second handle assembly 300, an electronic device 400 and a first square rod 140.

[0041] The lock body 100 includes a lock case 110, a spring bolt assembly 120 and a shifting sleeve 130. The spring bolt assembly 120 is slidably arranged in the lock case 110, so that the spring bolt assembly 120 is able to extend and retract relative to the lock case 110. The shifting sleeve 130 is rotatably arranged in the lock case 110, and the shifting sleeve 130 is in transmission connection with the spring bolt assembly 120. The first handle assembly 200 is provided with a locking head 510 and a motor 520. The locking head 510 is rotatably provided with a shifting head 511, and the shifting head 511 is in transmission connection with the shifting sleeve 130. An output shaft of the motor 520 is in transmission connection with the shifting head 511. The electronic device 400 includes a signal input module 410 and a main control module 420. The signal input module 410 is arranged in the first handle assembly 200, the main control module 420 may be arranged in the first handle assembly 200, and the signal input module 410 and the motor 520 are both electrically connected with the main control module 420. The signal input module 410 includes a fingerprint module 411 and a keyboard 412.

[0042] When a key is used to unlock the lock, a matched key is inserted into the locking head 510, and then the key is rotated forwardly. The shifting head 511 may rotate with the key, and the shifting sleeve 130 may rotate with the shifting head 511, thus driving the spring bolt assembly 120 to slide and retract into the lock case 110. When the key is used to lock the lock, the matched key is inserted into the locking head 510, and then the key is rotated reversely. When the lock is unlocked by a fingerprint or a password, a correct fingerprint or password is inputted through the signal input module 410, the main control module 420 controls the motor 520 to operate, the output shaft of the motor 520 rotates forwardly, and the shifting head 511 may rotate with the output shaft of the motor 520, thus driving the spring bolt assembly 120 to slide and retract into the lock case 110. When the lock needs to be locked, the main control module 420 controls the motor 520 to operate, so that the output shaft of the motor 520 rotates reversely.

[0043] As above, the motor 520 is arranged in the first handle assembly 200, and the motor 520 drives the spring bolt assembly 120 to slide through the shifting head 511 on the locking head 510, so that the lock body 100 does not need to be provided with the motor 520 and a transmission structure specially adapted with the motor 520, so as to be able to simplify a structure of the lock body 100 and reduce a thickness and a volume of the lock body 100.

[0044] In some embodiments, the main control module 420 may also be arranged in the second handle assembly 300.

[0045] Referring to FIG. 4, the spring bolt assembly 120 includes a spring bolt column 121 and a transmission member 122. The spring bolt column 121 and the transmission member 122 are fixedly connected, the transmission member 122 is provided with a guide groove 1221, and the guide groove 1221 is staggered with a sliding direction of the spring bolt assembly 120. The lock case 110 is rotatably provided with a first transmission gear 123, the first transmission gear 123 is provided with a shifting block 1231, and the shifting block 1231 is inserted into the guide groove 1221. The first transmission gear 123 is meshed with the shifting sleeve 130 for transmission, which means that the shifting sleeve 130 is provided with a second transmission gear 131, and the second transmission gear 131 is meshed with the first transmission gear 123, so that the shifting sleeve 130 is in transmission connection with the spring bolt assembly 120. A position of the shifting block 1231 deviates from an axis of the first transmission gear 123, and the first transmission gear 123 rotates around the axis, so that the shifting block 1231 may slide along the guide groove 1221 when the first transmission gear 123 rotates, thus pushing the spring bolt assembly 120 to slide.

[0046] In some embodiments, the transmission member 122 may also be provided with a rack, and the second transmission gear 131 on the shifting sleeve 130 is meshed with the rack, so that the shifting sleeve 130 is in transmission connection with the spring bolt assembly 120.

[0047] The door lock further includes a detection member 150. Referring to FIG. 4, the detection member 150 is arranged in the lock case 110. The detection member 150 is electrically connected with the main control module 420, and the detection member 150 is used for detecting a position of the spring bolt assembly 120. When the spring bolt assembly 120 extends and retracts to a limit position, the detection member 150 may be triggered. After the detection member 150 is triggered, a trigger signal is sent to the main control module 420, so that the main control module 420 may control the motor 520 to stop operating in time. The detection member 150 may be set as a Hall element for detecting a magnetic field strength, and correspondingly, a magnetic block is arranged on the spring bolt assembly 120. In addition, the detection member 150 may also be set as a photoelectric switch, a limiting switch or other structures.

[0048] A gear set 530 is arranged between the output shaft of the motor 520 and the shifting head 511, and the output shaft of the motor 520 is in transmission connection with the shifting head 511 through the gear set 530. When the output shaft of the motor 520 rotates, the shifting head 511 may be driven to rotate by the gear set 530.

[0049] For example, referring to FIG. 5, the gear set 530 includes a first gear 531 and a second gear 532. The first gear 531 is fixedly arranged on the output shaft of the motor 520, the second gear 532 is fixedly arranged on the shifting head 511, and the first gear 531 is meshed with the second gear 532. The first gear 531 and the second gear 532 are both set as spur gears, and a rotation axis of the shifting head 511 is parallel to an axis of the output shaft of the motor 520. Certainly, in some embodiments, the first gear 531 and the second gear 532 are both set as bevel gears, so that an included angle may be formed between a rotation axis of the shifting head 511 and the axis of the output shaft of the motor 520, and an installation orientation of the motor 520 has a greater flexibility.

[0050] In some embodiments, the gear set 530 may further include a third gear. The third gear is rotatably arranged in the first handle assembly 200, and the first gear 531, the third gear and the second gear 532 are sequentially meshed.

[0051] In some embodiments, the output shaft of the motor 520 may also be in transmission connection with the shifting head 511 through a belt structure or a coupler, so that the motor 520 is able to drive the shifting head 511 to rotate.

[0052] Referring to FIG. 3, one end of the first square rod 140 is inserted into the shifting head 511, and the first square rod 140 also penetrates through the shifting sleeve 130, so that the shifting head 511 may be in transmission connection with the shifting sleeve 130. When the shifting head 511 rotates, the shifting sleeve 130 may be driven to rotate by the first square rod 140. A part of one end of the first square rod 140 near the shifting head 511 may be cut off according to the thickness of the door leaf 720 during installation, so as to make a length of the first square rod 140 match with the thickness of the door leaf 720.

[0053] In some embodiments, the shifting head 511 and the shifting sleeve 130 may also be connected by the coupler and other structures.

[0054] Referring to FIG. 5, the first handle assembly 200 includes a first screw 210, as well as a first handle 220, a first handle base 230 and a first base plate 240 arranged in sequence. The first handle base 230 is set to have a hollow structure. The first screw 210 penetrates through the first base plate 240 and the first handle base 230, and the first screw 210 is in screwed connection with the first handle 220 to sandwich the first handle base 230 between the first handle 220 and the first base plate 240. The motor 520 and the locking head 510 are both inserted into an inner cavity of the first handle base 230, and the signal input module 410 is arranged in the first handle 220. The motor 520 and the locking head 510 may be inserted into the first handle base 230 first, and then the first handle assembly 200 is assembled through the structure during assembling, so that assembly of the first handle assembly 200 is relatively simple. The first handle assembly 200 has a small-sized single part and a simple structure, thus being convenient for processing.

[0055] The second handle assembly 300 is rotatably provided with a knob assembly 610, and the shifting sleeve 130 is in transmission connection with the knob assembly 610, so that the shifting sleeve 130 is able to rotate with the knob assembly 610. The second handle assembly 300 is also provided with a locking structure matched with the knob assembly 610, and rotation of the knob assembly 610 is able to be restricted by the locking structure, so as to play a role of double locking inside a door.

[0056] The other end of the first square rod 140 is inserted into the knob assembly 610, so that the knob assembly 610 may be in transmission connection with the shifting sleeve 130.

[0057] For example, referring to FIG. 3 and FIG. 6, a side wall of the first square rod 140 is concavely formed with a clearance-avoiding groove 141. The locking structure includes a locking block 621, the locking block 621 is slidably arranged in the second handle assembly 300, and the locking block 621 is provided with a locking hole 622 matched with the first square rod 140. The first square rod 140 penetrates through the locking hole 622, which means that the locking block 621 is sleeved on the first square rod 140.

[0058] When the double locking inside the door is needed, the spring bolt assembly 120 is driven to slide out of the lock case 110 first, so that the spring bolt assembly 120 is inserted into the door frame 720, and then the locking block 621 is pushed and pressed, so that the clearance-avoiding groove 141 is staggered with the locking hole 622. At the moment, the first square rod 140 is matched with the locking hole 622, and the knob assembly 610 and the first square rod 140 cannot rotate, so that the shifting sleeve 130 cannot rotate either. At the moment, neither the key nor the motor 520 can unlock the lock. The locking block 621 is pushed to move, so that the clearance-avoiding groove 141 is located in the locking hole 622. At the moment, the first square rod 140 is no longer matched with the locking hole 622, and the first square rod 140 is able to rotate relative to the locking hole 622. At the moment, the shifting sleeve 130 may be driven to rotate by rotating the knob assembly 610, and the shifting sleeve 130 may also be driven to rotate by the motor 520 or the key.

[0059] In some embodiments, the locking structure may include the locking block 621 and a limiting column. An end surface of the knob assembly 610 facing the lock body 100 is provided with a limiting hole, and the locking block 621 is provided with the limiting column. When the locking block 621 is pushed to slide, so that the limiting column is inserted into the limiting hole, the rotation of the knob assembly 610 may be restricted. When the limiting column moves out of the limiting hole, the knob assembly 610 may rotate. The limiting column is preferably tapered, so as to facilitate guiding insertion of the limiting column into the limiting hole.

[0060] In some embodiments, one end of the first square rod 140 may be inserted into the shifting head 511, and the other end of the first square rod 140 is inserted into or fixedly connected with the shifting sleeve 130. In addition, a second square rod is provided, one end of the second square rod is inserted into or fixedly connected with the knob assembly 610, and the other end of the second square rod is inserted into or fixedly connected with the shifting sleeve 130.

[0069] As described above, in the embodiment of the present invention, the locking head 510 and the motor 520 share the first square rod 140, and only the first square rod 140 needs to be arranged between the first handle assembly 200 and the lock body 100 to realize unlocking and locking in two power modes of key driving and motor 520 driving. A structure thereof is simple, without an additional transmission structure to connect the motor 520 with the shifting sleeve 130, so as to be able to simplify a transmission chain structure of the whole door lock, decrease a number of transmission parts, and reduce a cost.

[0070] In the embodiment of the present invention, the main control module 420 is in communication connection with the door opener 730, which means that the door lock is able to send a door opening signal to the door opener 730, and after the door opener 730 receives the door opening signal, the door opener 730 is operated to open the door automatically.

[0071] For example, the electronic device 300 further includes a first communication module 430 arranged in the second handle assembly 300, and the first communication module 430 is electrically connected with the main control module 420. The door opener 730 is provided with a second communication module 731, and the second communication module 731 is electrically connected with a main control system on the door opener 730. As a working mode, after the user inputs a correct fingerprint, password or iris through the signal input module 410, the main control module 420 controls the motor 520 to operate, so that the spring bolt assembly 120 retracts into the lock case 110. When the spring bolt assembly 120 retracts to the limit position, the detection member 150 is triggered and feeds a trigger signal back to the main control module 420. After receiving the trigger signal, the main control module 420 sends the door opening signal to the second communication module 731 through the first communication module 430, the second communication module 731 receives the door opening signal and feeds the door opening signal back to the main control system of the door opener 730, and the main control system controls the door opener 730 to open the door.

[0072] In some embodiments, the second communication module 731 may be arranged outside the door opener 730, which means that the second communication module 731 is not located on the door opener 730, and the second communication module 731 is electrically connected with the main control system of the door opener 730 through a wire and other structures. In addition, in some embodiments, the first communication module 430 may also be arranged in the first handle assembly 200.

[0073] In this way, when the user inputs the correct fingerprint or password through the signal input module 410, the door system is able to operate automatically, thus realizing fully automatic door opening and facilitating use by the user.

[0074] Referring to FIG. 6, the second handle assembly 300 is provided with a first button 361 and a second button 362, and both the first button 361 and the second button 362 are electrically connected with the main control module 420. When needing to open the door inside the door, the user may press the first button 361. After the first button 361 is pressed and triggered, the main control module 420 controls the motor 520 to operate and sends the door opening signal to the second communication module 731 through the first communication module 430, thus achieving the purpose of opening the door with one button and facilitating use by the user. When the user presses the second button 362, the door lock may enter a setting mode, thus being convenient for the user to set some information, such as inputting the fingerprint and changing the password. The first button 361 and the second button 362 may be a button switch or other structures.

[0075] Certainly, the present invention is not limited to the above embodiments. Those skilled in the art may further make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of the present application.
