The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0049] The terms "first", "second", "third" (if any) in the description and claims of this application and the above accompanying drawings are used to distinguish similar objects and do not have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of this application described herein can be implemented, for example, in an order other than those illustrated or described herein.

[0050] In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or display that comprises a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to those processes, methods, products or displays.

[0051] Wearable devices generally include keys and a main board. The main board is turned on through the keys to achieve ECG measurement. The keys generally include key caps and middle frames that cooperate with the key caps. The middle frames are fixed on the housing of the wearable device. A metal bar tube and a key spring are arranged between the key cap and the inner support. The key spring is sleeved on the metal bar tube, and the metal bar tube is sleeved on a metal screw. Press the key cap forcefully to make the metal screw contact and conduct with the steel sheet, and the steel sheet conducts with the main board, thereby realizing the conduction of the ECG test circuit.

[0052] However, the reliability of the conduction method of such wearable devices is relatively low. In this conduction method, it is necessary to make the key cap, key spring, metal bar tube, metal screw, steel sheet and main board conduct in sequence to achieve the conduction of the ECG test circuit. The test circuit requires more parts for conduction and has a longer conduction path, thus reducing the reliability of the conduction method. And when there are more parts, the part cost is higher and the assembly relationship is more complex, resulting in lower assembly efficiency.

[0053] Based on this, the embodiments of the present application provide a wearable device. By making the key, the conduction component and the circuit board component conduct in sequence, the conduction of the ECG test circuit is realized, the conduction path is shorter, and the reliability of the ECG test is improved.

[0054] The following elaborates in detail on the technical solutions of the wearable device provided by the embodiments of the present application with reference to the accompanying drawings.

[0055] Refer to Figures 1 to 3 As shown, the wearable device provided by the embodiments of the present application includes a housing 100, a circuit board component 200 and a conduction component 300. The circuit board component 200 and the conduction component 300 are both connected to the housing 100. The conduction component 300 includes a key 310 and a conduction piece 320. The key 310 includes a key cap 311 and a key rod 312 that are connected to each other.

[0056] The housing 100 has a receiving cavity 110. The conduction piece 320 is located in the receiving cavity 110 and is electrically connected to the circuit board component 200. The first end of the key rod 312 is connected to the key cap 311. The key cap 311 is configured to drive the key rod 312 to move relative to the housing 100 under an external force, so that the second end of the key rod 312 contacts and conducts with the conduction piece 320.

[0057] In this embodiment, the housing 100 is a support structure of the wearable device, which is used to mount the circuit board assembly 200 and the conduction assembly 300, so that the circuit board assembly 200 is relatively fixed, and the conduction assembly 300 can move relative to the housing 100 under the drive of an external force to conduct the circuit board assembly 200.

[0058] The circuit board assembly 200 is used to provide electrical energy and control signals for ECG measurement. Among them, the circuit board assembly 200 may include a flexible circuit board 210 and a main board 220. The flexible circuit board 210 is used to connect the conduction assembly 300 and the main board 220. Various circuits are integrated on the main board 220 to provide electrical energy, digital signals, analog signals, etc. for ECG measurement.

[0059] The conduction assembly 300 is used to conduct the ECG measurement circuit. Specifically, the conduction assembly 300 includes a button 310 and a conductor 320. The button 310 includes a button cap 311 and a button rod 312. The second end of the button rod 312, a part of the conductor 320, and a part of the flexible circuit board 210 are located in the accommodation cavity 110. An ECG contact is provided at the connection between the flexible circuit board 210 and the conductor 320. Before conduction, there is a gap between the second end of the button rod 312 and the conductor 320. The button cap 311 is used to apply an external force to drive the button cap 311 and the button rod 312 to move relative to the housing 100 toward the conductor 320, so that the second end of the button rod 312 contacts the conductor 320, thereby conducting the ECG measurement circuit.

[0060] Compared with the conduction method of the ECG measurement circuit in the prior art, the conduction assembly 300 provided in the embodiment of the present application only needs two parts, namely the button 310 and the conductor 320, to conduct with the circuit board assembly 200. The conduction path is shorter, thereby improving the reliability of ECG measurement. And the part cost is lower and the assembly is simpler, thereby improving the assembly efficiency of the wearable device.

[0061] The wearable device according to an embodiment of the present application includes a housing 100, a circuit board assembly 200, and a conduction assembly 300. The conduction assembly 300 includes a button 310 and a conduction member 320. The button 310 includes a button cap 311 and a button rod 312. By providing the housing 100 for mounting and fixing the circuit board assembly 200 and the conduction assembly 300, by providing the circuit board assembly 200 for providing electric energy and signals, the conduction assembly 300 is used for conducting the circuit board assembly 200 by providing the button 310 and the conduction member 320. The button 310 is used for applying an external force by providing the button cap 311 to drive the second end of the button rod 312 to contact and conduct with the conduction member 320. The conduction member 320 is used for electrically connecting with the circuit board assembly 200, so that the button cap 311, the button rod 312, the conduction member 320, and the circuit board assembly 200 are sequentially conducted to implement ECG measurement. Compared with the prior art, the wearable device according to the embodiment of the present application requires fewer parts for the conduction of the ECG measurement circuit and has a shorter conduction path, thereby improving the assembly efficiency of the wearable device and the reliability of ECG measurement.

[0062] Referring Figures 1 to 5 As shown, in specific implementation, the housing 100 includes a frame 120 and a middle frame 130 connected to the frame 120. The middle frame 130 is located on the side of the frame 120 away from the button cap 311, and the accommodation cavity 110 is provided in the middle frame 130.

[0063] A button slot 121 and a communication hole 122 are provided on the frame 120. The communication hole 122 is provided between the button slot 121 and the accommodation cavity 110 and communicates the button slot 121 and the accommodation cavity 110. The button cap 311 is provided in the button slot 121, and the button rod 312 extends into the accommodation cavity 110 through the communication hole 122.

[0064] It can be understood that the frame 120 is provided at the edge position of the wearable device for mounting the button 310, and the middle frame 130 can be used for mounting and fixing the circuit board assembly 200 and the conduction member 320. Specifically, the frame 120 has a button slot 121 for accommodating the button cap 311. The button cap 311 can reciprocally move relative to the button slot 121 along the extending direction of the button rod 312. That is, when an external force is applied to the button cap 311, the button cap 311 moves relative to the button slot 121 in the direction of the button rod 312. When the external force disappears, the button cap 311 moves relative to the button slot 121 in the direction away from the button rod 312 to turn on or off the ECG measurement function.

[0065] The frame 120 also has a communication hole 122 for enabling the button rod 312 to extend into the accommodation cavity 110. The extending direction of the communication hole 122 is consistent with the extending direction of the button rod 312. The communication hole 122 can also be used to guide the button cap 311 and the button rod 312 to reciprocally move along the same straight line all the time.

[0066] Reference Figure 2 As shown in Figure 6 In specific implementation, the conducting member 320 includes a body 321, a first conducting portion 322, and a second conducting portion 323. The body 321 is annular. The first conducting portion 322 is in the shape of a tongue and is connected to the inner side of the body 321. The second conducting portion 323 is connected to the outer side of the body 321, and the second conducting portion 323 is bent towards the circuit board assembly 200. The second conducting portion 323 is electrically connected to the circuit board assembly 200. When the key rod 312 moves towards the accommodation cavity 110 relative to the frame 120, the second end of the key rod 312 contacts and conducts with the first conducting portion 322.

[0067] In this way, the conducting member 320 is provided with the body 321 for connecting the first conducting portion 322 and the second conducting portion 323. The body 321 can be circular or semi-circular. The tongue-shaped first conducting portion 322 is arranged on the inner side of the body 321 so that the first conducting portion 322 is correspondingly arranged with the second end of the key rod 312, facilitating the contact or disconnection between the second end of the key rod 312 and the first conducting portion 322, thereby enabling the key rod 312 to conduct or open circuit with the conducting member 320.

[0068] By arranging the second conducting portion 323 on the outer side of the body 321, the conducting member 320 is electrically connected to the flexible circuit board 210 through the second conducting portion 323, and the bent second conducting portion 323 will not collide with the key 310 during assembly, facilitating the assembly of the conducting member 320 onto the middle frame 130.

[0069] Reference Figure 6 As shown in Figure 7 In a possible implementation, the conducting member 320 further includes at least one hot melt connection portion 324. The hot melt connection portion 324 and the second conducting portion 323 are located on the same side of the body 321, and the hot melt connection portion 324 is arranged at an angle with the body 321. There are hot melt posts 131 on the middle frame 130, and the hot melt connection portions 324 are in one-to-one hot melt connection with the hot melt posts 131.

[0070] Thus, the conducting member 320 can be connected to the hot melt posts 131 of the middle frame 130 through the hot melt connection portions 324, thereby mounting and fixing the conducting member 320 on the side of the middle frame 130. The hot melt connection portion 324 can be perpendicularly arranged with the body 321. In this way, the hot melt connection portion 324 is parallel to the side of the middle frame 130, and the body 321 and the first conducting portion 322 are perpendicular to the axial direction of the key rod 312, facilitating the contact between the key rod 312 and the first conducting portion 322.

[0071] It can be understood that two hot-melt connection parts 324 can be arranged on the conduction part 320, and the two hot-melt connection parts 324 are located on both sides of the second conduction part 323 to enhance the connection stability of the conduction part 320. Correspondingly, two hot-melt connection posts are arranged on the side surface of the middle frame 130. By connecting the conduction part 320 and the middle frame 130 in a hot-melt manner, the conduction part 320 can be firmly fixed on the middle frame 130, thereby improving the reliability of the conduction part 320.

[0072] Referring to Figure 8 With Figure 9 As shown, in some embodiments, the wearable device provided by the embodiment of the present application further includes an insulating part 400. The insulating part 400 is located between the button 310 and the frame 120, and the insulating part 400 is connected to the frame 120. The insulating part 400 is configured to insulate the button 310 and the frame 120.

[0073] It can be understood that for the sake of beauty, the frame 120 is usually made of a metal material and has conductive characteristics. Insulation can be carried out between the button cap 311 and the frame 120 and between the button rod 312 and the frame 120 through the insulating part 400 to prevent the current of the button cap 311 and the button rod 312 from flowing to the frame 120. Compared with the prior art where a decorative insulating ring and a lim injection plastic ring need to be set for insulation, the wearable device of this embodiment only needs to set one insulating part 400 to insulate the button 310 and the frame 120, which can simplify the process and structure, facilitate assembly, and thus improve the assembly efficiency.

[0074] Referring to Figures 9 to 11 As shown, in specific implementation, the insulating part 400 includes a first insulating part 410, a second insulating part 420, and a third insulating part 430. The second insulating part 420 is disc-shaped. One end of the first insulating part 410 is connected to the second insulating part 420, and the other end extends in a direction away from the second insulating part 420 to form an annular flange on the first side of the second insulating part 420. The third insulating part 430 is tubular, and one end of the third insulating part 430 is connected to the second side of the second insulating part 420, and the other end extends in a direction away from the second insulating part 420.

[0075] The first insulating part 410 is inserted into the button groove 121, and the outer side wall of the first insulating part 410 is bonded to the inner side wall of the button groove 121. The third insulating part 430 is sleeved on the button rod 312.

[0076] In this way, by providing the first insulating portion 410 on the insulating member 400 and sleeving the first insulating member 400 on the key cap 311, the outer side wall of the key cap 311 is insulated from the frame 120. By providing the second insulating portion 420 and making the second insulating portion 420 contact the bottom of the key slot 121, the surface of the key cap 311 facing the key rod 312 is insulated from the frame 120. Thus, the key cap 311 and the frame 120 can be insulated from each other through the first insulating portion 410 and the second insulating portion 420.

[0077] By providing the third insulating portion 430 and sleeving the third insulating portion 430 on the key rod 312, the key rod 312 is insulated from the frame 120. Thus, the insulating member 400 can insulate the key 310 from the frame 120. By bonding the outer side wall of the first insulating portion 410 to the inner side wall of the key slot 121, the insulating member 400 is connected to the frame 120, thereby fixing the insulating member 400 to the frame 120.

[0078] Referring to Figure 3 and Figure 9 As shown, in a possible implementation, the wearable device provided by the embodiment of the present application further includes a sealing assembly 500. The sealing assembly 500 includes at least one first seal 510. An annular first receiving groove 3121 is provided on the outer peripheral side of the key rod 312. The first seal 510 is sleeved on the first receiving groove 3121, and the first seal 510 abuts against the inner side wall of the third insulating portion 430 to seal the gap between the key rod 312 and the third insulating portion 430.

[0079] It can be understood that since the key rod 312 needs to move relative to the third insulating portion 430, there is a gap between the outer side wall of the key rod 312 and the inner side wall of the third insulating portion 430. In this way, by providing the first seal 510 and the first receiving groove 3121 on the key rod 312, after the first seal 510 is sleeved on the first receiving groove 3121, the gap between the key rod 312 and the third insulating portion 430 can be sealed to prevent water and the like from entering the receiving cavity 110.

[0080] Among them, the first seal 510 can be an O-ring. Compared with the lim injection plastic seal of the prior art, the structure and process of the first seal 510 are relatively simple.

[0081] Referring to Figure 9 and Figure 11As shown, in some embodiments, the sealing assembly 500 includes at least one second seal 520, and an annular second receiving groove 431 is provided on the outer peripheral side of the third insulating part 430, the second seal 520 is sleeved on the second receiving groove 431, and the first seal 510 abuts against the inner wall of the middle frame 130 to seal the gap between the third insulating part 430 and the frame 120.

[0082] Thus, the first sealing member 510 can seal the gap between the third insulating portion 430 and the frame 120 to prevent water and the like from entering the accommodation cavity 110 through the gap between the third insulating portion 430 and the frame 120. The second sealing member 520 can be an O-ring.

[0083] Reference Figure 3 and Figure 4 As shown, in a possible implementation, the wearable device provided in the embodiment of the present application also includes at least two elastic members, at least two elastic members are located on both sides of the button cap 311, the button cap 311 has a mounting groove 3111 on the side facing the button rod 312, the mounting groove 3111 is arranged in a one-to-one correspondence with the elastic member, the first end of the elastic force direction of the elastic member abuts against the bottom of the mounting groove 3111, the second end of the elastic force direction of the elastic member abuts against a side of the second insulating portion 420 facing the first insulating portion 410, and the elastic force direction of the elastic member points to the direction of the button cap 311 away from the button rod 312.

[0084] It is understandable that an elastic member is provided on both sides of the key cap 311, which is conducive to uniform force on the key cap 311 and better pressing and rebounding effects. When an external force is applied to the key cap 311, the elastic member is compressed, and the elastic member has elastic potential energy after elastic deformation. In this way, when the external force disappears, the elastic potential energy is converted into kinetic energy, and the elastic member can drive the key cap 311 to drive the key rod 312 to move away from the accommodating cavity 110, so that the second end of the key rod 312 is out of contact with the first conductive portion 322.

[0085] Reference Figure 3 and Figure 9 As shown, in order to avoid excessive elastic force of the elastic member, driving the button rod 312 to completely detach from the accommodating cavity 110, the wearable device provided in the embodiment of the present application also includes a limit member 600, and the outer peripheral side of the button rod 312 has an annular limit groove 3122, and the limit groove 3122 is located on the side of the first accommodating groove 3121 away from the button cap 311, and the limit member 600 is clamped on the limit groove 3122. When the external force disappears, the limit member 600 abuts against the end face of the third insulating portion 430 away from the second insulating portion 420.

[0086] In this way, when the external force disappears, the elastic force of the elastic member drives the key rod 312 to move away from the accommodation cavity 110. When the key rod 312 moves to a position where the limiting member 600 abuts against the end face of the third insulating portion 430 facing away from the second insulating portion 420, the key rod 312 cannot move further, thereby preventing the second end of the key rod 312 from detaching from outside the accommodation cavity 110. Among them, the limiting member 600 is an E-type circlip.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
