[0037] With the development of technology and the diversification of smart product functions, more and more wearable electronic products are beginning to integrate ECG (electrocardiogram) functions. In related technologies, ECG functions are achieved by setting ECG electrodes on buttons and fixing conductive springs to the button levers, and connecting the conductive springs to the detection circuit board inside the product. However, this technology is not suitable for wearable electronic products that require button turning functions.

[0038] In view of this, some embodiments of this application provide a wearable device that allows users to operate buttons more flexibly without being restricted by conductive connectors. Users can press the buttons at different angles and directions, ensuring that the button operation is accurately transmitted to the internal circuit board. It can adapt to different operation needs, such as rotation operation and pressing operation, providing users with more operation options.

[0039] The present application will be described in detail below through specific embodiments:

[0040] The wearable device in the embodiments of this application, such as Figure 1-5 As shown, a wearable device includes:

[0041] The device includes a button 10 and a conductive connector 20. The button 10 can be pressed along the rotation axis of the button 10. The conductive connector 20 is used to electrically connect to the internal circuit board of the wearable device. The conductive connector 20 includes an assembly part 21 and an anti-rotation part 22. The assembly part 21 is rotatably connected to the button 10 so that the button 10 can rotate relative to the conductive connector 20. The anti-rotation part 22 is used to prevent the conductive connector 20 from rotating with the button lever 12.

[0042] The wearable device provided in this application embodiment has a button 10 for user operation to trigger corresponding functions. The button 10 is rotatably connected to the conductive connector 20, enabling relative movement between the button 10 and the conductive connector 20 to a certain extent. The button 10 is allowed to rotate relative to the conductive connector 20. The anti-rotation part 22 prevents the conductive connector 20 from rotating along with the button 10, ensuring the stable position of the conductive connector 20 inside the wearable device. By allowing button 10 to rotate relative to conductive connector 20 and to be pressed along the axis of rotation of button 10, users can operate button 10 more flexibly without being restricted by conductive connector 20. Users can press button 10 at different angles and directions, improving the convenience and comfort of operation. This ensures that the operation of button 10 is accurately transmitted to the internal circuit board, avoiding insensitivity or false triggering of button 10 due to interference from conductive connector 20. Users can press button 10 more easily and obtain accurate feedback, improving the user experience. At the same time, wearable devices usually have multiple functions, requiring different button 10 operation methods to realize them. This design of button 10 and conductive connector 20 can adapt to different operation needs, such as rotation operation and pressing operation, providing users with more operation options.

[0043] It should be noted that wearable devices can be smartwatches, smart bracelets, etc. This embodiment will be described using a smartwatch as an example.

[0044] Specifically, such as Figure 4 As shown, the button 10 includes a button body 11 and a button lever 12 connected to the button body 11. The button lever 12 extends along the rotation axis, and the mounting part 21 is movably sleeved on the button lever 12.

[0045] The button body 11 is used for direct user operation to trigger corresponding functions. The button lever 12 is connected to the button body 11 and serves to transmit the user's operating force. The assembly part 21 of the conductive connector 20 is movably sleeved on the button lever 12. During the assembly process of the conductive connector 20, the movable sleeve allows the assembly part 21 to quickly connect with the button lever 12 without complicated alignment and fixing operations, thus improving production efficiency. The movable sleeve structure makes the button 10 smoother during pressing and releasing, without any jamming or unresponsiveness, improving the user's operating experience.

[0046] In this embodiment, as Figure 1-2 As shown, the wearable device also includes a housing 30, with an assembly opening 31 on the side wall of the housing 30. The button body 11 is located on the side of the side wall facing the human body. The conductive connector 20 is located inside the housing 30. The button lever 12 passes through the assembly opening 31 and is assembled with the conductive connector 20. The anti-rotation part 22 cooperates with the housing 30 to prevent the conductive connector 20 from rotating with the button lever 12.

[0047] The anti-rotation part 22 cooperates with the housing 30 to effectively prevent the conductive connector 20 from rotating when the button lever 12 rotates. This ensures that the conductive connector 20 always maintains the correct position inside the wearable device, ensuring a stable connection with the internal circuit board and improving the overall structural stability of the device. If the conductive connector 20 rotates with the button lever 12, it may cause its connection with the internal circuit board to become loose or have poor contact, affecting the normal operation of the device. The button body 11 is located on the side wall of the housing 30 facing the human body for convenient operation. The assembly method of the button lever 12 and the conductive connector 20 makes the operation of the button 10 and the function of the conductive connector 20 independent. When the user presses the button 10, they will not be affected by the rotation of the conductive connector 20, improving the convenience and accuracy of operation.

[0048] Of course, in other possible implementations, the anti-rotation part 22 can also cooperate with other components inside the housing 30 to achieve the anti-rotation function, thereby preventing the conductive connector 20 from rotating with the button lever 12.

[0049] In one possible implementation, such as Figure 2 As shown, the housing 30 has a groove 32 inside, and both the anti-rotation part 22 and the groove 32 extend along the axial direction of the button rod 12. The anti-rotation part 22 is located inside the groove 32.

[0050] The anti-rotation part 22 is positioned within the groove 32 extending axially along the button lever 12, providing clear guidance and constraint. This ensures that the anti-rotation part 22 can only move axially along the button lever 12, following the button 10, and is firmly constrained in other directions, enhancing the anti-rotation effect and ensuring that the conductive connector 20 does not rotate unnecessarily when the button lever 12 rotates, thus guaranteeing the stability of the device's internal structure. The groove 32 provides a clear installation position for the anti-rotation part 22, allowing for more accurate positioning of the conductive connector 20 to the housing 30 during assembly, improving assembly precision and consistency, and reducing problems that may be caused by assembly errors. Positioning the anti-rotation part 22 within the groove 32 of the housing 30 fully utilizes the internal space of the device without occupying additional space, making the wearable device more compact and lightweight, improving wearing comfort and portability.

[0051] Specifically, such as Figure 5 As shown, the conductive connector 20 includes a spring body 23 and a bent portion 24 connected to the spring body 23. The assembly portion 21 and the anti-rotation portion 22 are both connected to the bent portion 24. The bent portion 24 and the spring body 23 are spaced apart along the axial direction of the button rod 12.

[0052] By connecting a bent portion 24 to the spring body 23, and with the bent portion 24 and the spring body 23 spaced apart along the axial direction of the button rod 12, the bent portion 24 can bear a certain amount of deformation in the axial direction of the button rod 12 when the button 10 is operated or subjected to external pressure. This can better disperse stress, thereby extending the service life of the conductive connector 20 and ensuring the reliability of the equipment. At the same time, the bent portion 24 provides better connection and support for the assembly portion 21 and the anti-rotation portion 22, increasing the overall structural strength of the conductive connector 20, improving the stability of the conductive connector 20 during use, and reducing deformation or damage caused by external forces.

[0053] In other possible implementations, the assembly part 21 and the anti-rotation part 22 may also be directly connected to the spring body 23.

[0054] Furthermore, in one possible implementation, such as Figure 5 As shown, the anti-rotation part 22 is arranged perpendicular to the bending part 24.

[0055] The anti-rotation part 22 is positioned perpendicular to the bending part 24, forming a stable right-angle structure. Since the bending part 24 and the spring body 23 are spaced apart along the axial direction of the button rod 12, when the anti-rotation part 22 is perpendicular to the bending part 24 and extends along the axial direction of the button rod 12, the anti-rotation part 22 can withstand the same anti-rotation force when the button rod 12 rotates in any direction. This ensures the stability of the conductive connector 20 during use and improves the overall structural stability of the device. Simultaneously, the vertically positioned anti-rotation part 22 facilitates better coordination with the groove 32 of the housing 30, allowing for a more compact internal structure of the wearable device, saving space, and contributing to miniaturization and weight reduction.

[0056] In another possible implementation, the anti-rotation part 22 may also be inclined to the bending part 24, and correspondingly, the groove 32 in the housing 30 is in the same inclination direction as the anti-rotation part 22.

[0057] In this embodiment, as Figure 5 As shown, the assembly part 21 and the bending part 24 are located on the same plane.

[0058] The assembly part 21 and the bending part 24, being on the same plane, can form a more stable structure. When the button 10 is operated or subjected to external forces, it can better withstand various stresses, reducing the risk of deformation and damage, and improving the overall structural stability of the conductive connector 20. During use, the force can be more evenly distributed on the assembly part 21 and the bending part 24, avoiding localized stress concentration and thus extending the service life of the conductive connector 20 and ensuring the reliability of the equipment. The fact that the assembly part 21 and the bending part 24 are on the same plane ensures smoother cooperation between the button lever 12 and the conductive connector 20 during rotation, reducing jamming and friction, improving the feel and comfort of the button 10 operation, and providing a better user experience.

[0059] In other embodiments, the assembly portion 21 and the bending portion 24 may also be spaced apart along the axial direction.

[0060] In one possible implementation, such as Figure 5 As shown, the assembly part 21 includes a first latching arm 211 and a second latching arm 212, which are spaced apart. The button lever 12 is rotatably latched between the first latching arm 211 and the second latching arm 212.

[0061] The first locking arm 211 and the second locking arm 212 are spaced apart, allowing the button lever 12 to be clamped from two opposite directions. This clamping method provides more stable support, preventing the button lever 12 from wobbling or shifting during rotation, thus improving structural stability. Simultaneously, the spaced locking arms ensure a more even distribution of clamping force on the button lever 12, avoiding localized stress concentration that might occur with single-point clamping, reducing the risk of deformation of the button lever 12 and the locking arms, and extending the service life of the components. This design also simplifies the assembly of the button lever 12; installation is completed simply by inserting the button lever 12 between the first locking arm 211 and the second locking arm 212, eliminating the need for complex connection methods or tools, improving assembly efficiency, and reducing production costs.

[0062] In another possible implementation, a flexible ring arm with a notch can be used for snapping, with the notch being less than half a circle.

[0063] Furthermore, such as Figure 5 As shown, the surfaces of the first latching arm 211 and the second latching arm 212 that are in contact with the button lever 12 are concave arc surfaces 25. The first latching arm 211 includes a latching part 2111 for latching with the button lever 12 and a connecting part 2112 for connecting with the bent part 24. Similarly, the second latching arm 212 has two connecting parts 2112 connected near the bent part 24, so that a circular latching space and a U-shaped deformation space are formed between the first latching arm 211 and the second latching arm 212.

[0064] The concave arc surface 25 better matches the shape of the button lever 12. When the button lever 12 rotates between the locking arms, it reduces frictional resistance, making rotation smoother. Users will not feel any sticking or stiffness when operating the button 10, improving operational comfort and convenience. The concave arc surface 25 design better encloses the button lever 12, increasing the contact area and improving clamping stability. During the pressing or releasing of the button 10, the button lever 12 is less prone to wobbling or shifting, ensuring operational accuracy and reliability. The clamping force on the button lever 12 is more evenly distributed, avoiding localized stress concentration, reducing the risk of deformation of the button lever 12 and the locking arms, and extending the service life of the components.

[0065] In other embodiments, when the button lever 12 is square or other shapes, the surfaces of the first latching arm 211 and the second latching arm 212 that are in contact with the button lever 12 can also be set to square to achieve a good clamping effect.

[0066] In this embodiment, as Figure 4 As shown, the button lever 12 is provided with a first protruding ring 121 and a second protruding ring 122 along the axial direction, and the assembly part 21 is movably sleeved between the first protruding ring 121 and the second protruding ring 122.

[0067] The first protruding ring 121 and the second protruding ring 122 can accurately position the assembly part 21 in the axial direction. The assembly part 21 is movably sleeved between the two protruding rings, so that when the button rod 12 is pressed in the axial direction, it drives the conductive connector 20 to move, so that the assembly part 21 and the button rod 12 always remain in a relatively fixed state, increasing the connection stability between the button rod 12 and the conductive connector 20. At the same time, movably sleeved the assembly part 21 between the first protruding ring 121 and the second protruding ring 122 can prevent the assembly part 21 from accidentally falling off the button rod 12, ensuring that the conductive connector 20 can maintain a good connection with the button rod 12 under various operating conditions.

[0068] In other possible implementations, an annular groove is provided on the button lever 12, and the assembly part 21 is movably fitted into the annular groove.

[0069] In this embodiment, as Figure 3 As shown, a retaining ring 80 is engaged between the button lever 12 and the button body 11 and the first protruding ring 121. The retaining ring 80 is located inside the housing 30 and cooperates with the assembly port 31 so that the button 10 can only be pressed in the direction of the inside of the housing 30 and will not move in the direction away from the housing 30.

[0070] In this embodiment, as Figure 3As shown, the wearable device also includes a flexible circuit board 40 and an ECG detection circuit board 50. The button body 11 is provided with ECG electrodes. One end of the flexible circuit board 40 is electrically connected to the conductive connector 20, and the other end of the flexible circuit board 40 is electrically connected to the ECG detection circuit board 50.

[0071] By setting ECG electrodes on the button body 11 and connecting them to the flexible circuit board 40 and the ECG detection circuit board 50, the wearable device can realize the electrocardiogram (ECG) detection function. When performing ECG detection, the user only needs to operate the button 10 to start the detection function, which is very convenient and quick. The flexible circuit board 40 is flexible and thin, and its layout and shape can be adjusted according to the specific design requirements of the wearable device, making the internal structure of the device more compact and reasonable.

[0072] Specifically, such as Figure 6-7 As shown, the flexible circuit board 40 includes a circuit board body 41, a first bending portion 42, and a second bending portion 43 connected in sequence. The first bending portion 42 and the circuit board body 41 are spaced apart along the axial direction of the button lever 12, and the second bending portion 43 and the first bending portion 42 are spaced apart along the axial direction of the button lever 12. The first bending portion 42 is electrically connected to the conductive connector 20.

[0073] The wearable device also includes a mounting bracket 60. A circuit board body 41 is mounted on the mounting bracket 60 in a direction perpendicular to the button lever 12. A button switch 70 is provided on the circuit board body 41 facing the button lever 12. The button lever 12 is axially pressed by pressing the button switch 70. A first bent portion 42 is spaced apart from the circuit board body 41 along the axial direction of the button lever 12. A second bent portion 43 is spaced apart from the first bent portion 42 along the axial direction of the button lever 12. The first bent portion 42 is electrically connected to the spring body 23 of the conductive connector 20. Thus, when the button lever 12 is pressed axially, the first bent portion 42 and the second bent portion 43 can move in the axial direction of the button lever 12 without affecting the feel of the button 10.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
