In the present embodiment, the middle frame 100 may be disposed in a square shape, and the material of the middle frame 100 may be metal, so as to improve the structural strength of the middle frame 100. In some embodiments, the middle frame 100 may also be disposed in a circular shape, an oval shape, or a triangular shape, which is not limited in this embodiment.

Further, the oppositely disposed first and third sidewalls 110, 130 may be used in connection with the strap 20 such that a user may wear the electronic device 10 on the wrist through the strap 20. As shown in fig. 4, a side of the first sidewall 110 facing away from the third sidewall 130 may be provided with an attachment slot 1101, and the attachment slot 1101 may be used to mount the strap 20. Correspondingly, the side of the third side wall 130 facing away from the first side wall 110 may also be provided with the connecting slot 1101, so that the two opposite sides of the middle frame 100 may be provided with the straps 20, thereby wearing the electronic device 10 by using the straps 20 on the two opposite sides.

Meanwhile, the mounting groove 1103 may be formed in an L shape to match with the shape of the elastic conductive element 500, so that the mounting groove 1103 may limit the elastic conductive element 500, thereby preventing the position of the elastic conductive element 500 from deviating and affecting the electrical connection between the elastic conductive element 500 and the first circuit board 300 and the second circuit board 400. Accordingly, the side of the fourth sidewall 140 close to the second sidewall 120 may be further provided with a screw hole 1104, so that the bracket 600 may be connected with the fourth sidewall 140 by a screw to be fixed on the fourth sidewall 140.

Referring to fig. 7 to 8, fig. 7 is a schematic view illustrating a connection structure of the middle frame 100, the second circuit board 400, the support 600 and the first electrode 700 in fig. 3, and fig. 8 is a schematic view illustrating a partial cross-sectional structure of the middle frame 100, the second circuit board 400, the support 600 and the first electrode 700 in fig. 7 along vi-vi.

As shown in fig. 7 to 8, a bracket 600 may be disposed on a side of the fourth sidewall 140 close to the second sidewall 120, and may be used to support the second circuit board 400 to fix the second circuit board 400 on the fourth sidewall 140. The bracket 600 may be disposed opposite to the receiving groove 1102 and the mounting groove 1103, so that the second circuit board 400 disposed on the bracket 600 may also be disposed opposite to the receiving groove 1102 and the mounting groove 1103, so that the second circuit board 400 is electrically connected to the elastic conductive member 500 and the first electrode 700, respectively. The second circuit board 400 may be disposed on a side of the bracket 600 near the fourth sidewall 140, and the second circuit board 400 may also be a circuit board for triggering a key function. The second circuit board 400 may be a flexible circuit board, such that the second circuit board 400 may extend from one side of the bracket 600 close to the fourth sidewall 140 to one side of the bracket 600 away from the fourth sidewall 140, so that the second circuit board 400 is connected to a main control board in the electronic device 10, thereby implementing a key function of the electronic device 10. Accordingly, the first electrode 700 may be a side key of the electronic device 10, which not only can be used as a detection electrode to realize the electrocardiographic detection function of the electronic device 10, but also can be used as a key to realize the key function of the electronic device 10. In some embodiments, the second circuit board 400 may also be a rigid circuit board, so that the second circuit board 400 may be directly fixed to the fourth sidewall 140 by screws.

The first electrode 700 may include: a key 710, a conductive spring 720 and a conductive pillar 730. The key 710 may be disposed in the accommodating groove 1102, the conductive resilient piece 720 may be disposed on one side of the second circuit board 400 close to the accommodating groove 1102, and the conductive pillar 730 may penetrate through the fourth sidewall 140 and is connected to the key 710 and the conductive resilient piece 720 respectively. The key 710 may have a conductive property, so that when a user touches the key 710, a corresponding electrical signal may be triggered to be transmitted to the second circuit board 400 through the conductive post 730 and the conductive elastic sheet 720, and then transmitted to the first circuit board 300 through the elastic conductive member 500, so as to form a detection loop through conduction with the second electrode 800, thereby implementing an electrocardiographic detection function of the electronic device 10. Meanwhile, the key 710 is further configured to drive the conductive pillar 730 to displace toward the direction close to the second circuit board 400 by pressing, so that the conductive pillar 730 can contact with the key contact 410 on the second circuit board 400, thereby implementing the key function of the electronic device 10.

Specifically, the key 710 can be disposed in the receiving groove 1102, and the key 710 can slide in the receiving groove 1102 in a direction approaching to or departing from the second sidewall 120, so that a user can press the key 710. Since the keys 710 are electrically conductive and the middle frame 100 is made of metal, in order to avoid electrical communication between the middle frame 100 and the keys 710, the outer surface of the middle frame 100 may be injection molded to form a corresponding plastic surface for insulating the middle frame 100 and the keys 710. Or insulating treatment is performed only on the surface where the middle frame 100 and the key 710 may contact, such as attaching an insulating film or spraying an insulating material. Meanwhile, the middle frame 100 and the keys 710 can be electrically connected by insulating the keys 710. As shown in fig. 8, the keys 710 may include: an insulating part 711, and a pressing part 712. The insulating portion 711 can be disposed in the receiving groove 1102 and can slide in the receiving groove 1102 in a direction approaching to or departing from the second sidewall 120, so as to implement the pressing function of the key 710. The pressing portion 712 may be disposed on a side of the insulating portion 711 opposite to the second sidewall 120, and the pressing portion 712 may be made of metal, so as to realize the conductive function of the key 710.

Further, the insulating portion 711 may further cooperate with the fourth sidewall 140 to limit the movement stroke of the button 710, so as to prevent the button 710 from falling out of the receiving slot 1102. As shown in fig. 8, two opposite sides of the insulating portion 711 may be provided with a first connecting portion 7111 and a second connecting portion 7112, the first connecting portion 7111 may be clamped with an inner wall of the receiving groove 1102 in a direction away from the second sidewall 120, and the second connecting portion 7112 may be clamped with a limiting pin B inserted in the receiving groove 1102 in a direction away from the second sidewall 120, so as to prevent the key 710 from coming out of the receiving groove 1102 in a pressing process. Meanwhile, in order to ensure the pressing reliability of the key 710, a first elastic member 740 is further disposed between the insulating part 711 and the inner wall of the accommodating groove 1102, and the first elastic member 740 is configured to generate an elastic force to push the insulating part 711 to displace in a direction away from the second sidewall 120 after the insulating part 711 displaces in a direction close to the second sidewall 120, so as to reset the key 710, reduce the probability that the key 710 cannot rebound after being pressed, and ensure the pressing reliability of the key 710. In this embodiment, a side of the insulating portion 711 facing away from the second sidewall 120 may further protrude from the receiving groove 1102, so that a user can press the pressing portion 712, thereby implementing a key function of the electronic device 10.

The conductive pillar 730 can be used to electrically connect the pressing portion 712 and the second circuit board 400, so that the key 710 can be conducted with the second electrode 800 to implement the electrocardiograph detection function of the electronic device 10. Meanwhile, the conductive posts 730 can also be used to contact the key contacts 410 on the second circuit board 400 to trigger the key function of the key 710. As shown in fig. 8, the conductive pillar 730 may penetrate through the fourth sidewall 140, and one end of the conductive pillar 730 may be connected to the conductive elastic piece 720, and the other opposite end may be connected to the pressing portion 712. In order to ensure the connection reliability between the conductive post 730 and the pressing portion 712 and the conductive elastic sheet 720. The second elastic element 731 may be disposed between the conductive pillar 730 and the pressing portion 712, and the second elastic element 731 may respectively abut against the pressing portion 712 and the conductive pillar 730, so as to ensure the electrical reliability of the conductive pillar 730 and the pressing portion 712. Accordingly, the conductive post 730 can also abut against the conductive elastic piece 720, so as to ensure the electrical connection reliability of the conductive post 730 and the conductive elastic piece 720. Thus, when a user touches the pressing portion 712, an electrical signal can be transmitted to the second circuit board 400 through the conductive pillar 730 and the conductive elastic sheet 720, and then transmitted to the first circuit board 300 through the elastic conductive member 500, so as to be conducted with the second electrode 800, thereby implementing an electrocardiographic detection function of the electronic device 10. When a user applies an acting force to the key 710, the pressing portion 712 can drive the conductive pillar 730 to move toward the second circuit board 400, so that the conductive pillar 730 contacts the key contact 410 on the second circuit board 400, thereby implementing a key function of the electronic device 10. In this embodiment, the first elastic member 740 and the second elastic member 731 may be metal springs, so that the second elastic member 731 has a conductive property while having a deformation capability.

Referring to fig. 9 to 10, fig. 9 is a schematic view illustrating a connection structure of the rear case 200, the first circuit board 300 and the second electrode 800 in fig. 3, and fig. 10 is a schematic view illustrating a cross-sectional structure of the rear case 200, the first circuit board 300 and the second electrode 800 in fig. 9 along line viii-viii.

The rear case 200 may cover one side of the middle frame 100 and surround the middle frame 100 to form the accommodating space 101. As shown in fig. 9 to 10, the rear case 200 may include: a first cover 210 and a second cover 220. The first cover 210 may cover one side of the middle frame 100, and together with the middle frame 100, the first cover 210 and the middle frame 100 form an accommodating space 101, and the first cover 210 may further have a light-transmitting opening 211. The second cover 220 may be disposed on a side of the first cover 210 away from the middle frame 100, and the second cover 220 may further cover the light-transmitting opening 211. In this embodiment, the first cover 210 may be configured to dispose the first circuit board 300, the second cover 220 may be configured to dispose the second electrode 800, so as to implement an electrocardiographic detection function of the electronic device 10, and the second cover 220 may further have a light-transmitting area, which is configured to cooperate with the first circuit board 300 to implement an optical detection function of the electronic device 10.

The first circuit board 300 may be an electrocardiograph circuit board, and is used to implement an electrocardiograph detection function of the electronic device 10. The first circuit board 300 may include: a main control board 310 and a connection board 320. The main control board 310 may be disposed on a side of the first cover 210 close to the second cover 220, and the main control board 310 may further cover the light-transmitting opening 211 and be disposed opposite to the second cover 220, so that the second electrode 800 on the second cover 220 is electrically connected to the main control board 310. For example, the second electrode 800 may be electrically connected to the main control board 310 through a flexible circuit board or a solder joint. In some embodiments, an optical detection module may be further disposed on the main control board 310, and the optical detection module may obtain heart rate data of the user by receiving reflected light emitted by the optical detection module onto the body of the user, so that the electronic device 10 may perform detection by using the optical detection module in cooperation with the first electrode 700 and the second electrode 800, so as to improve accuracy and reliability of the electrocardiographic detection function of the electronic device 10. The main control board 310 may be a hard circuit board, so that a corresponding detection module is integrated on the main control board 310 to implement an electrocardiographic detection function of the electronic device 10. In some embodiments, the first circuit board 300 may also be a main board of the electronic device 10, and only the first circuit board 300 needs to be integrated with a corresponding electrocardiograph detection module to implement the electrocardiograph detection function.

The connection board 320 may be connected to the main control board 310, and the connection board 320 may be further disposed in a region of the first cover 210 close to the fourth side wall 140, so that the connection board 320 abuts against the elastic conductive member 500 on the fourth side wall 140, thereby achieving conduction between the first electrode 700 and the second electrode 800. Meanwhile, in order to make the direction of the elastic force exerted by the elastic conductive member 500 on the first cover 210 through the connection plate 320 parallel to the thickness direction X, the region where the connection plate 320 abuts against the elastic conductive member 500 may also be connected to the first cover 210 in a direction perpendicular to the thickness direction X. In this embodiment, the connection board 320 may be a flexible circuit board, so as to reduce the stacking space occupied by the connection board 320 in the accommodating space 101 while the elastic conductive member 500 is electrically connected to the main control board 310. In some embodiments, the first circuit board 300 may also only include the main control board 310, and only the main control board 310 can be disposed in a region of the first cover 210 close to the fourth side wall 140, so that the elastic conductive member 500 can abut against the main control board 310, and an elastic direction between the elastic conductive member 500 and the main control board 310 is parallel to the thickness direction X.

Meanwhile, the first elastic part 510, the second elastic part 520, the fixing part 530, the extending part 540, the first position-limiting part 550 and the second position-limiting part 560 may be an integral structure, so as to improve the structural strength of the elastic conductive member 500.

As shown in fig. 11 and 12, the fixing portion 530 may be disposed in the mounting groove 1103 and opposite to the second circuit board 400, and a side of the fixing portion 530 close to the bracket 600 has a first surface 531. The first elastic portion 510 may be disposed on a side of the fixing portion 530 close to the bracket 600, that is, the first surface 531, so that the first elastic portion 510 is abutted against the second circuit board 400. An adhesive layer 141 is disposed between the fixing portion 530 and the inner wall of the mounting groove 1103, so as to fix the fixing portion 530 on the fourth sidewall 140. One end of the first elastic portion 510 may be connected to the fixing portion 530, and the other end may be arched toward the second circuit board 400, so that the first elastic portion 510 may protrude from the mounting groove 1103, so that the first elastic portion 510 abuts against the second circuit board 400. Meanwhile, the other end of the first elastic part 510 may also be suspended between the fixing part 530 and the second circuit board 400, so that the first elastic part 510 deforms to abut against the second circuit board 400. When the bracket 600 is assembled to the fourth sidewall 140, the second circuit board 400 on the bracket 600 may contact the first elastic portion 510 and push the first elastic portion 510 toward the fixing portion 530, so that the first elastic portion 510 is elastically deformed to generate an elastic force to abut against the second circuit board 400. In this manner, the first elastic part 510 and the second circuit board 400 can be brought into close contact, thereby ensuring the electrical connection reliability of the first elastic part 510 and the second circuit board 400. In the present embodiment, the elastic direction between the first elastic part 510 and the second circuit board 400 may be perpendicular to the thickness direction X. Meanwhile, the fixing portion 530 may be disposed in a plate shape, and two opposite sides of the fixing portion 530 may be folded to improve the structural strength of the fixing portion 530.

As shown in fig. 11 and 13, the extending portion 540 may also be disposed in the mounting groove 1103, and the extending portion 540 may be disposed on a side of the fixing portion 530 close to the connecting plate 320 and opposite to the connecting plate 320. The extension 540 may further have a second surface 541, and the second surface 541 is connected to the first surface 531 and is disposed vertically. The second elastic portion 520 may be disposed on a side of the extending portion 540 close to the connecting plate 320, that is, a surface of the extending portion 540 away from the second surface 541, so that the second elastic portion 520 abuts against the connecting plate 320. Wherein, extension 540 can also set up with fixed part 530 is perpendicular, and extension 540 and fixed part 530 can also be "L" shape setting in the appearance to with the shape looks adaptation of mounting groove 1103, not only can be convenient for extension 540 and connecting plate 320 set up relatively, can also make between fixed part 530 and the extension 540 can carry out spacing each other, avoid taking place the skew at the position of butt in-process elastic conductive component 500. One end of the second elastic portion 520 may be connected to the extending portion 540, and the other end may be arched toward a direction close to the connecting plate 320, so that the second elastic portion 520 may be disposed to protrude from the mounting groove 1103, so that the second elastic portion 520 abuts against the connecting plate 320. Meanwhile, the other end of the second elastic part 520 may be suspended between the extension part 540 and the connection plate 320, so that the second elastic part 520 is deformed to abut against the connection plate 320. When the elastic conductive member 500 is assembled to the fourth sidewall 140, the second elastic portion 520 may contact the connection plate 320 and may be displaced in a direction approaching the extension 540 by the pushing of the connection plate 320, so as to be elastically deformed to abut against the connection plate 320. In this manner, it is possible to make the second elastic part 520 and the connection plate 320 in close contact, thereby securing the electrical connection reliability of the second elastic part 520 and the connection plate 320.

Accordingly, since the connection plate 320 and the extension 540 are both arranged in a direction perpendicular to the thickness direction X, the elastic direction between the second elastic part 520 and the connection plate 320 can be parallel to the thickness direction X, so that the elastic force exerted by the second elastic part 520 on the first cover 210 through the connection plate 320 is a forward elastic force parallel to the thickness direction X, and the problem that the first cover 210 is subjected to a lateral elastic force from the second elastic part 520 when the first cover 210 is assembled with the middle frame 100, so that the first cover 210 is deflected in the assembling process, the assembling gap between the first cover 210 and the middle frame 100 is inconsistent, and the waterproof adhesive between the first cover 210 and the middle frame 100 is delaminated is avoided, thereby improving the assembling reliability and waterproof property of the rear case 200 and the middle frame 100. Meanwhile, the problem that the reliability of the electrical connection between the connection plate 320 and the second elastic portion 520 is reduced or fails due to insufficient abutting force between the connection plate 320 and the second elastic portion 520 after the first cover 210 is deflected can be avoided. In addition, compared with the connection between the connection board 320 and the second circuit board 400 through BTB, the connection board 320 is limited by the BTB assembly space, so that the connection board 320 can be connected to the second circuit board 400 only by surrounding the accommodating space 101. The elastic conductive member 500 provided in this embodiment may not be limited by the BTB assembly space, and directly transmit the electrical signal of the key on the second circuit board 400 to the first circuit board 300, so as to shorten the layout length of the connection board 320 and the second circuit board 400, thereby achieving the purpose of reducing the electrical signal transmission path, and improving the sensitivity and reliability of the electrocardiographic detection of the electronic device 10.

The first position-limiting portion 550 may be connected to the extending portion 540, and the first position-limiting portion 550 may be bent toward the connecting plate 320 to form an "L" shape. The first stopper portion 550 may be used to limit the movement of the second elastic portion 520 in a direction approaching the connection plate 320. For example, the other end of the second elastic portion 520, which is suspended between the extending portion 540 and the connecting plate 320, may be overlapped to a side of the first limiting portion 550, which is opposite to the extending portion 540, so that the second elastic portion 520 may be engaged with the first limiting portion 550 in a direction close to the connecting plate 320, so as to limit the movement of the second elastic portion 520 in the direction close to the connecting plate 320, and prevent the second elastic portion 520 from exerting an elastic force on the connecting plate 320 without limitation and affecting the assembly of the first cover 210 and the middle frame 100 in the thickness direction X. The second position-limiting portion 560 may also be connected to the extending portion 540, and the second position-limiting portion 560 may extend toward the extending portion 540 away from the connecting plate 320. The second limiting portion 560 may extend to a side of the bracket 600 close to the fourth sidewall 140, and the second limiting portion 560 may further abut against the bracket 600, so that when the bracket 600 is assembled to the fourth sidewall 140, the elastic conductive member 500 may abut against the fourth sidewall 140 through the second limiting portion 560, that is, abut against the mounting groove 1103, thereby limiting the movement of the elastic conductive member 500 in a direction in which the bracket 600 is away from the fourth sidewall 140, and preventing the elastic conductive member 500 from coming out of the mounting groove 1103. In this embodiment, since the second position-limiting portion 560 abuts against the bracket 600, when the bracket 600 is made of metal, an insulating layer 610 may be further disposed between the second position-limiting portion 560 and the bracket 600 to maintain electrical insulation between the elastic conductive element 500 and the bracket 600. Meanwhile, the insulating layer 610 may also be disposed to wrap the region of the bracket 600 near the elastic conductive member 500, so as to further enhance the insulation reliability between the elastic conductive member 500 and the bracket 600.

In some embodiments, the elastic conductive member 500 may also be provided with only the first elastic part 510 and the second elastic part 520. For example, the first elastic portion 510 and the second elastic portion 520 may be separate elastic pieces, and both of them may be embedded in the fourth sidewall 140 and abut against the second circuit board 400 and the connection board 320, respectively. Accordingly, the first elastic part 510 and the second elastic part 520 may be electrically connected by, for example, a coaxial cable or a flexible circuit board to electrically communicate the second circuit board 400 and the connection board 320. Alternatively, in other embodiments, the elastic conductive member 500 may be only abutted against the connection plate 320. For example, the elastic conductive element 500 may not be provided with the first elastic part 510, and the fixing part 530 may be directly soldered on the second circuit board 400 to be electrically connected with the second circuit board 400. The second elastic portion 520 and the extension portion 540 may still be disposed as in the above embodiments, and only the elastic direction between the second elastic portion 520 and the connecting plate 320 is parallel to the thickness direction X. In addition, in some embodiments, the fixing portion 530 may also be directly connected to the conductive elastic piece 720 on the second circuit board 400, that is, the fixing portion 530 and the conductive elastic piece 720 may be an integral structure, and the second elastic portion 520 and the extending portion 540 may still be disposed as in the above embodiments, only the elastic direction between the second elastic portion 520 and the connecting plate 320 is parallel to the thickness direction X.

Thus, compared to the scheme that the connection board 320 and the second circuit board 400 are connected through the BTB, the elastic conductive member 500 in the embodiment of the present application can shorten the transmission path of the electrical signal of the key 710, so as to avoid attenuation or interference of the electrical signal during transmission, and improve the sensitivity and reliability of the electrocardiographic detection function of the electronic device 10. Meanwhile, by arranging the first elastic part 510 to abut against the second circuit board 400 and the second elastic part 520 to abut against the connecting plate 320, the electrical connection reliability of the elastic conductive member 500 with the second circuit board 400 and the connecting plate 320 can be improved. In addition, by arranging that the direction of the elastic force between the first elastic part 510 and the second circuit board 400 is perpendicular to the thickness direction X, and the direction of the elastic force between the second elastic part 520 and the connecting plate 320 is parallel to the thickness direction X, the problem that the assembly position of the first cover 210 relative to the middle frame 100 is deviated due to the lateral elastic force from the second elastic part 520 when the first cover 210 is assembled with the middle frame 100, so that the assembly gap between the first cover 210 and the middle frame 100 is not uniform and the waterproof adhesive is layered can be avoided, and the assembly reliability and the waterproof property of the first cover 210 and the middle frame 100 are improved.

In some embodiments, the electronic device 10 may further be provided with a display screen, and the display screen may be disposed on a side of the middle frame 100 away from the rear shell 200, which may be used to implement an image display function of the wearable device 5, so that a user may view data information of the wearable device 5, such as time, temperature, weather, two-dimensional code, walking steps, and the like, through the display screen. The display screen may include a transparent cover plate, a display panel, and a touch panel, which are stacked. The touch panel is arranged between the transparent cover plate and the display panel. The transparent cover plate is mainly used to protect the display panel, and may serve as an outer surface of the wearable device 5. Meanwhile, the surface of the transparent cover plate has the characteristics of flatness and smoothness, so that a user can conveniently perform touch operation such as clicking, sliding and pressing. The display panel is mainly used for displaying pictures and can be used as an interactive interface to instruct a user to perform the touch operation on the transparent cover plate. The touch panel is mainly used for responding to the touch operation of the user, converting the corresponding touch operation into an electric signal and transmitting the electric signal to the processor of the wearable device 5, so that the wearable device 5 can make a corresponding reaction to the touch operation of the user. In this embodiment, the Display screen may use a screen of an OLED (Organic Light-Emitting Diode) for image Display, or may use a screen of an LCD (Liquid Crystal Display) for image Display.
