[0055] In an embodiment, as illustrated in FIG. 9, the third contact plane 182 is provided with a second accommodating groove 184 for accommodating the locking member 19, so as to facilitate the locking member 19 to connect the first connecting member 17 and the second connecting member 18. In an embodiment, when the first contact plane 172 of the first connecting member 17 is in contact with the third contact plane 182 of the second connecting member 18, the second connecting member 18 slides in the extension direction of the first contact plane 172 until the second contact plane 173 is in contact with the fourth contact plane 183, the first accommodation groove 174 is opposite to the second accommodation groove 184 and forms an integral space for accommodating the locking member 19.

[0056] In an embodiment, the third contact plane 182 is perpendicular to the fourth contact plane 183, such that the first connecting member 17 and the second connecting member 18 may relatively slide to each other to achieve the connection and disconnection of each other.

[0057] In an embodiment, the second bump 185 protrudes from an edge of the fourth contact plane 183. The second bump 185 and the second main body 181 form a second socket 186. The second bump 185 cooperates with the second socket 186 to form a second buckling position, such that the second bump 185 and the first connecting member 17 may be buckled together in a staggered way. In an embodiment, when the first connecting member 17 is engaged with the second connecting member 18, the first bump 175 is located in the second socket 186, and the second bump 185 is located in the first socket 176, realizing the staggered fastening of the first connecting member 17 and the second connecting member 18.

[0058] In an embodiment, the second bump 185 protrudes along the second direction B at the edge of the fourth contact plane 183. The second direction B is parallel to the third contact plane 182 and parallel to the fourth contact plane 183.

[0059] In an embodiment, as shown in FIG. 9, two second connecting members 18 are provided on the connecting ring 15, and the second bump 185 of one of the second connecting members 18 is located on the fourth contact plane 183 away from the edge of one side of the other second connecting member 18. Of course, for the two second connecting members 18 provided on the connecting ring 15, the second bump 185 of one of the second connecting members 18 may also be located at the fourth contact plane 183 close to the edge of one side of the other second connecting member 18. The two second bumps 185 extend towards the same direction.

[0060] As shown in FIG. 8 and FIG. 9, the locking member 19 may be placed in both of the first accommodating groove 174 and the second accommodating groove 184, thus avoiding the relative sliding of the first connecting member 17 and the second connecting member 18. Moreover, the staggered fastening of the first buckling position and the second buckling position may prevent the relative rotation of the first connecting member 17 and the second connecting member 18. At the same time, the first connecting member 17 may be prevented from moving to a side away from the second connecting member 18, and the second connecting member 18 may be prevented from moving to a side away from the first connecting member 17, completely realizing the connection between the first connecting member 17 and the second connecting member 18, and further realizing the connection between the connecting ring 15 and the main housing body 11.

[0061] In an embodiment, the locking member 19 may include an elastic member 191 and a locking head 192. The elastic member 191 and the locking head 192 are disposed in the first accommodating groove 174. One end of the elastic member 191 abuts against the first main body 171 in the elastic direction, and the other opposite end of the elastic member 191 abuts against the locking head 192, such that the locking head 192 may be at least partially placed in the first accommodating groove 174. When one side of the locking head 192 away from the elastic member 191 is not squeezed, the stretching force of the elastic member 191 pushes the locking head 192 to slide in a direction away from the side of the elastic member 191, and then the locking head 192 is partially placed in the first accommodating groove 174. When one side of the locking head 192 away from the elastic member 191 is squeezed, the locking head 192 is subjected to an extrusion force such that the locking head 192 slides in a direction close to the side of the elastic member 191, and then the whole locking head 192 is placed in inside the first accommodating groove 174.

[0062] In an embodiment, the elastic member 191 may be a spring or be made of an elastic plastic material, and of course the elastic member 191 may also be made of other elastic materials.

[0063] In an embodiment, as shown in FIG. 10 and FIG. 11, FIG. 10 is a partial cross-sectional view of the main housing body 11 and the connecting ring 15 connected to each other according to the embodiment shown in FIG. 9 of the present disclosure, FIG. 11 is a cross-sectional view of a part C of the main housing body 11 and the connecting ring 15 connected to each other according to the embodiment shown in FIG. 10 of the present disclosure. An end of the locking head 192 away from the elastic member 191 is a spherical surface, facilitating the compression of the locking head 192 that follows the relative sliding to each other of the first connecting member 17 and the second connecting member, and realizing the connection and disconnection between the first connecting member 17 and the second connecting member 18. In an embodiment, in order to disassemble of the first connecting member 17 and the second connecting member 18, the length of the locking head 192 exposed to the first accommodating groove 174 is equal to the radius of the spherical end of the locking head 192.

[0064] In an embodiment, in order to prevent the locking head 192 from sliding out of the first accommodation groove 174 completely, for example, from sliding out of the mouth of the first accommodating groove 174, a limiting member may be provided in the first accommodating groove 174. For example, structures such as bumps, protruding rings, and screws may be used to limit the locking head 192 such that the locking member 19 is at least partially placed in the first accommodating groove 174.

[0065] It may be understood that the locking member 19 may also not be arranged in the first accommodating groove 174, but be arranged in the second accommodating groove 184 instead. The arrangement manner of the locking member 19 shown in FIG. 8 may be referred as the arrangement manner of the locking member 19 being disposed in the second accommodating groove 184.

[0066] When the connecting ring 15 is to be connected to the main housing body 11, the first contact plane 172 is in contact with the third contact plane 182, such that the first bump 175 is facing the second socket 186, and the second bump 185 is facing the first socket 176, then the connecting ring 15 slides in the extension direction of the first contact plane 172 until the second contact plane 173 contacts the fourth contact plane 183. During the sliding process, the first bump 175 gradually slides into the second socket 186, and the second bump 185 gradually slides into the first socket 176. In addition, during the sliding process, the locking head 192 is squeezed by the second connecting member 18 and completely slides into the first accommodating groove 174, and the elastic member 191 is squeezed and in a compressed state. When the second contact plane 173 is in contact with the fourth contact plane 183, the first accommodating groove 174 is opposite to the second accommodating groove 184, and under the stretching force of the elastic member 191, the locking head 192 is ejected and slides into the second accommodating groove 184. In this case, the locking head 192 is partially placed in the first accommodating groove 174, and partially placed in the second accommodating groove 184. The disassembling process may be operated in reverse.

[0067] Of course, in order to facilitate the installation and disassembly of the first connecting member 17 and the second connecting member 18, an adjustment hole the same as the first accommodating groove 174 may also be provided in the first main body 171 of the first connecting member 17. Through the adjustment hole, an instrument may be used to abut against the locking head 192 so a force is implemented on the locking head 192 and the force may push the locking head 192 to slide toward one side of the elastic member 191, realizing the installation and disassembly of the first connecting member 17 and the second connecting member 18.

The second housing 20 may be buckled with the first housing 10, and may be provided with the measuring electrode 70 and some parts of the mainboard assembly 30. The second housing 20 may be a plate-like structure. The second housing 20 may be made of rigid insulating material, so the second housing 20 may also be called “insulating housing”. In an embodiment, the second housing 20 may be made through plastic injection molding process. The surface of the second housing 20 facing the top plate 111 and the surface away from the top plate 111 may be planar. Of course, the surface of one side of the second housing 20 facing the top plate 111 may be convex to the side close to the top plate 111 to form a curved surface, or may be concave to the side away from the top plate 111 to form a curved surface. The surface of one side of the second housing 20 away from the top plate 111 may be concave to the side close to the top plate 111 to form a curved surface, or may be convex to the side away from the top plate 111 to form a curved surface.

[0071] In an embodiment, mounting holes 21 such as a first mounting hole 211 and a second mounting hole 212 may be defined in the second housing 20 for mounting some parts of the mainboard assembly 30.

[0072] In an embodiment, the surface of the second housing 20 away from the top plate 111 is a contact surface 22 for being contacted with the human body. The measuring electrode 70 may be set on the contact surface 22 to facilitate the contact between the measuring electrode 70 and the human body, and then the human body, the measuring electrode 70 and the mainboard assembly 30 form an ECG signal measurement circuit.

[0073] In an embodiment, the second housing 20 may be fixed with the first housing 10 through buckle structure, screw connection structure, adhesive bonding, etc. The second housing 20 is connected to one side of the side wall 112 (such as the first side wall 113, the second side wall 114, the third side wall 115, and the fourth side wall 116) away from the top plate 111. The edge of the surface of the second housing 20 away from the top plate 111 is flush with the edge of the side wall 112 away from the top plate 111.

The mainboard assembly 30 is installed in the accommodating space, and is configured to be electrically connected with the battery 40, the indicator light 50, the balance electrode 60, the measuring electrode 70, and the display module. Therefore, it is convenient for the mainboard assembly 30 to control the battery 40 to perform charging and discharging operations, for the mainboard assembly 30 to control the indicator light 50 to present the working state of the wearable device 100, for the mainboard assembly 30 to complete the ECG signal detection through the balance electrode 60 and the measuring electrode 70, for the mainboard assembly 30 to control the display module to display information such as an electrocardiogram generated by the ECG signals, and for the mainboard assembly 30 to control the wearable device 100 to exchange data with external devices. The mainboard assembly 30 may include a mainboard 31 and a connecting head 32. Various electronic components such as processors and sensors may be integrated on the mainboard 31. The mainboard 31 may be fixed on the first housing 10 by screws, glue and other structures. The mainboard 31 may be electrically connected to the connecting head 32, the battery 40, the indicator light 50, the balance electrode 60, the measuring electrode 70, and the display module, such that power transmission may be realized. For example, the connecting head 32 may be connected to the commercial power to charge the battery 40. For example, the mainboard 31 may control the battery 40 to supply power to the indicator light 50, the balance electrode 60, the measuring electrode 70, and the display module. The mainboard 31 may be provided with a driven-right-leg circuit so as to be electrically connected with the balanced electrode 60. The driven-right-leg circuit is essentially negative feedback. The function of the driven-right-leg circuit is to remove the common-mode signal of the input amplifier by adopting the common-mode voltage as the reverse input of the drive circuit, so as to improve the common mode rejection ratio (CMRR) and realize the accuracy of the ECG parameters obtained from the ECG signals collected by the measuring electrode 70.

[0075] In an embodiment, elastic members such as a first elastic member 311 and a second elastic member 312 are disposed on the mainboard 31, such that the elastic members such as the first elastic member 311 and the second elastic member 312 abut against the connecting head 32 to realize electrical connection.

[0076] In an embodiment, the connecting head 32 may be a pogo pin connector. The connecting head 32 may include a first conductive column 321 and a second conductive column 322. The mainboard 31 may be connected to a power source such as the commercial power to obtain electric energy through the connecting head 32 such as the first conductive column 321 and the second conductive column 322. The mainboard 31 may be electrically connected with the measuring electrode 70 through the connecting head 32 (such as the first conductive column 321 and the second conductive column 322), such that the measuring electrode 70 may be connected with the mainboard 31 to form an ECG signal detection circuit. In an embodiment, the processor on the mainboard 31 calculates the user’s heart rate after processing the ECG signals, and generates an electrocardiogram. A Bluetooth module may also be integrated on the mainboard 31, and the bluetooth transmission of the electrocardiogram may be realized through the Bluetooth module and an external device such as a mobile phone.

[0077] As shown in FIG. 17, the connecting head 32 such as the first conductive column 321 and the second conductive column 322 are installed on the second housing 20 such as in the mounting hole 21. Specifically, the first conductive column 321 is provided with a sealing ring 3211. The second conductive column 322 is provided with a sealing ring 3221. The first conductive column 321 is installed in the first mounting hole 211, the second conductive column 322 is installed in the second mounting hole 212, and the seal connection between the connecting head 32 and the second housing 20 is realized through the sealing ring 3211 and the sealing ring 3221. The sealing ring 3211 and the sealing ring 3221 are elastic soft rubber rings. In an embodiment, both of the first conductive column 321 and the second conductive column 322 are interference-fitted with the second housing 20 to realize installation. In an embodiment, one end portion of the connecting head 32 such as the first conductive column 321 and the second conductive column 322 away from the mainboard 31 is electrically connected to the measuring electrode 70. In an embodiment, one end portion of the connecting head 32 such as the first conductive column 321 and the second conductive column 322 away from the mainboard 31 is configured to be connected to a power source such as the commercial power, such that the wearable device 100 may obtain electric energy.

[0078] As shown in FIG. 18, one end portion of one side of the connecting head 32 such as the first conductive column 321 near the mainboard 31 abuts against the first elastic member 311 to realize electrical connection. One end portion of one side of the connecting head 32 such as the second conductive column 322 near the mainboard 31 abuts against the second elastic member 312 to realize electrical connection.

[0079] As shown in FIG. 3 and FIG. 4, the balance electrode 60 is electrically connected to the mainboard 31, and specifically may be connected to the driven-right-leg circuit on the mainboard 31. Therefore, the balance electrode 60 is also called “Driven-Right-Leg Electrode”. The balance electrode 60 is disposed on one side of the first housing 10 away from the second housing 20. Specifically, the balance electrode 60 may be disposed on any position (such as the connection ring 15 and the top plate 111) of the first housing 10 that may be touched by the user’s fingers and other parts. It is certain that in some embodiments, in order to install the display module, the balance electrode 60 may be disposed on the edge of the top plate 111 to reserve an installation position for the display module. The balance electrode 60 may cooperate with the measuring electrode 70 to form a complicated ECG signal measuring circuit. For example, the wearable device 100 may be worn on the left wrist of the user, and the measuring electrode 70 is in contact with the left wrist to measure the ECG signals, the balance electrode 60 is touched by the right hand, and the reverse common-mode ECG signals are generated after the mainboard 31 inverts the common mode ECG signals collected by the measuring electrode 70, then the reverse common-mode ECG signals are input to the human body through the balanced electrode 60 until the measurement is completed. The accuracy of ECG parameters may be improved. In an embodiment, the balance electrode 60 may be omitted.

[0080] As shown in FIG. 4 and FIG. 15, the measuring electrode 70 may be metal-plated, which is convenient to be contacted with the human body for ECG signal measurement and the transmission of ECG signals. A wear-resistant metal coating may be deposited on the surface of the second housing 20 by water plating and/or vacuum plating to obtain the measuring electrode 70. The measuring electrode 70 may also be a metal sheet arranged on the surface of the second housing 20 by means of bonding or bayonet connection. The measuring electrode 70 may include a first electrode 71 and a second electrode 72 arranged at intervals on the contact surface 22. In order to realize the construction of the ECG signal detection circuit, the first electrode 71 is electrically connected to the first conductive column 321, and the second electrode 72 is electrically connected to the second conductive column 322, such that the first electrode 71, the first conductive column 321, the second conductive column 322, and the mainboard 31 are connected to form an ECG signal detection circuit, and the mainboard 31 may obtain ECG parameters according to the ECG signals collected by the first electrode 71 and the second electrode 72.

[0081] As shown in FIG. 16, one surface of one side of the second housing 20 near the top plate 111 is a first surface 23, and one surface (i.e., the side surface) connecting the first surface 23 and the contact surface 22 is a connecting surface 24. In addition to being arranged on the contact surface 22, the first electrode 71 and the second electrode 72 may also be arranged on the first surface 23 or the connecting surface 24. As a result, the first electrode 71 is electrically connected to the first conductive column 321 in the accommodating space, and the second electrode 72 is electrically connected to the second conductive column 322 in the accommodating space.

[0082] It may be understood that a portion of the first electrode 71 located on the contact surface 22 may be directly electrically connected to the first conductive column 321, and a portion of the second electrode 72 located on the contact surface 22 may be directly electrically connected to the second conductive column 322.

The strap 600 may include a first strap 601 and a second strap 605.

The wearing of the wearable device 100 may be realized by the ring structure formed by connecting the first strap 601, the second strap 605, and the electronic device 300 sequentially from end to end.

[0084] In an embodiment, as shown in FIG. 2, an integral structure is formed due to that the first end 602 of the first strap 601 is connected to the first end 606 of the second strap 605. The electronic device 300 is fixed on the strap 600. The second end 603 of the first strap 601 is connected to the second end 607 of the second strap 605 through a third connecting member 604 and a fourth connecting member 608. In an embodiment, the third connecting member 604 and the fourth connecting member 608 are bayonet-connected.

[0085] In an embodiment, as shown in FIG. 12 and FIG. 14, the second end 603 of the first strap 601 is connected with the second end 607 of the second strap 605 to form an integral structure. The first end 602 of the first strap 601 is connected to the first end 301 (in other words, the first connection ring 151) of the electronic device 300, and the first end 606 of the second strap 605 is connected to the second end 302 (in other words, the first connection ring 151) of the electronic device 300.

In an embodiment, the third connecting member 604 and the fourth connecting member 608 are bayonet-connected. In an embodiment, one of the third connecting member 604 and the fourth connecting member 608 may be one of the first connecting member 17 and the second connecting member 18, and the other one of the third connecting member 604 and the fourth connecting member 608 may be the other one of the first connecting member 17 and the second connecting member 18.
