Description

Technical Field

[0001] The present application relates to the technical field of electronic devices, and particularly to a switch component and a wearable electronic device. Background Art

[0002] In modern electronic devices, as an important structure for user-device interaction, switch components are widely used in various consumer electronic products, such as mobile phones, computers, televisions, home appliances, wearable electronic devices, etc. With the progress of technology, the design of switch components increasingly tends to be miniaturized, thinner, and highly reliable.

[0003] The main structure of the switch component includes a button, a bracket, an elastic member, and a switch member. The button includes a keycap and a key rod. After pressing the keycap, the key rod moves relative to the bracket to trigger the switch member. When the pressing on the keycap is released, the elastic member drives the button to reset. In order to keep the button stable in the reset position and prevent the button from disengaging from the bracket, a corresponding limiting structure needs to be provided.

[0004] In some related technologies, corresponding flanges or snap structures are provided at the edge of the keycap to form a blocking effect with the bracket to achieve limiting. This method requires changing the structures of both the keycap and the bracket simultaneously, resulting in a complex product structure and increasing the processing and assembly costs. In other related technologies, a snap spring is sleeved on the key rod, and a limiting effect is formed between the snap spring and the bracket. However, in this method, the snap spring and the key rod are in a detachable socket fit, and there will be slight shaking in the limiting state, and the connection is not stable, and there is a risk of the snap spring falling off. Summary of the Invention

[0005] The present application provides a switch component and a wearable electronic device to solve the technical problems in the related art that the limiting structure of the button in the switch component is complex or there is a risk of part detachment.

[0006] The first aspect of the present application provides a switch component, which includes:

[0007] A bracket, on which a through first shaft hole is provided;

[0008] A button, including a keycap and a key shaft, the key shaft passes through the first shaft hole and can move axially along the first shaft hole. One end of the key shaft away from the keycap forms a first shaft section. The keycap and the first shaft section are respectively located on both sides of the bracket, and the first shaft section has a first abutting surface facing the bracket;

[0009] A limiting member, arranged between the first shaft section and the bracket;

[0010] A reset member, configured to make the first abutting surface always have a tendency to move axially along the first shaft hole towards the limiting member;

[0011] A switch member is disposed on a side of the first shaft segment away from the keycap. When the key is pressed, the first shaft segment moves toward the switch member and triggers the switch member.

[0012] A second aspect of the present application provides a wearable electronic device, which includes the switch assembly provided in the first aspect of the present application.

[0013] The above technical solutions provided by the embodiments of the present application have the following advantages compared with the prior art: Due to the presence of the reset member, when the key is in a natural state without being pressed by an external force, the first abutting surface abuts against the limiting member; when the user presses the keycap and the key moves toward the switch member against the reset force of the reset member, the third abutting surface will gradually approach and press against the switch member to trigger the switch member. After the user releases the key in the pressed state, the reset member drives the key shaft to move axially along the axial hole of the first shaft, so that the first abutting surface contacts the limiting member, and the key is reset. The limiting member plays a role in limiting the other extreme position, so that the key shaft cannot be disengaged from the bracket. On the one hand, the embodiments of the present application utilize the reset force of the reset member to cooperate with the abutment between the first abutting surface and the limiting member to achieve axial limitation of the key to prevent the key from coming out, without the need to additionally provide limiting components such as buckles or screws, which simplifies the product structure and reduces the assembly complexity; on the other hand, the limiting member in the embodiments of the present application is a fixed structure, and the first shaft segment is the structure of the key shaft itself. Compared with sleeving a snap spring on the key shaft for limitation, the contact limitation between the first shaft segment and the limiting member can improve the stability in the limited state and reduce the risk of part detachment.

Detailed implementation manners

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0033] The main structure of the switch assembly provided by the embodiments of the present application includes a bracket 110, a key 130, a limiting member 120, a reset member 140 and a switch member 160. The switch assembly is an important part of various electronic devices. As a trigger interaction structure for users to interact with electronic devices, it can be widely used in various consumer electronic devices. The types of electronic devices include but are not limited to mobile phones, tablet computers, scanning pens, digital cameras, smart watches, etc. This specification takes this switch assembly as an example applied to Figure 1 , Figures 4 - 5An exemplary description will be given by taking the wearable electronic device of the smart watch type shown as an example.

[0034] As Figures 1 - 13 As shown, a through first shaft hole 111 is formed in the bracket 110 of the switch assembly. The first shaft hole 111 specifically penetrates from the first side of the bracket 110 to the second side. The button 130 includes a keycap 132 and a key shaft 131. The key shaft 131 penetrates through the first shaft hole 111 and can move along the axial direction of the first shaft hole 111. The keycap 132 is located on the first side of the bracket 110. One end of the key shaft 131 away from the keycap 132 forms a first shaft section 1311. The keycap 132 and the first shaft section 1311 are respectively located on both sides of the bracket 110. A first abutting surface 1314 facing the bracket 110 is provided on the first shaft section 1311. The limiting member 120 is arranged between the first shaft section 1311 and the bracket 110. The reset member 140 is configured to make the first abutting surface 1314 always have a tendency to move axially along the first shaft hole 111 toward the limiting member 120. The switch member 160 is arranged on the side of the first shaft section 1311 away from the keycap 132. When the button 130 is pressed, the first shaft section 1311 moves toward the switch member 160 and triggers the switch member 160.

[0035] In the above embodiment, the bracket 110 is used for fixedly connecting to a specific electronic device. As the main load-bearing structure, it is also used to carry the button 130, the reset member 140, and the limiting member 120. The button 130 is used to move along the first shaft hole 111 after being pressed to trigger the switch member 160 as a traditional physical button. The switch member 160 is used to be directly or indirectly connected to the circuit system of the electronic device to transmit an electrical signal to the circuit system.

[0036] The keycap 132 of the button 130 is a structure suitable for finger touch and pressing. Its surface can be provided with anti-slip textures and a suitable surface area according to needs to suit finger touch and pressing. The keycap 132 is arranged on the first side of the bracket 110. The keycap 132 itself protrudes radially relative to the key shaft 131. During the process of the key shaft 131 moving along the first shaft hole 111 toward the switch member 160, when the keycap 132 abuts against the bracket 110, it will be blocked and unable to move. The keycap 132 can play a role in limiting the extreme position.

[0037] The first shaft section 1311 is located at one end of the key shaft 131 away from the keycap 132. A first abutting surface 1314 is machined on the surface of the first shaft section 1311 facing the limiting member 120, and a third abutting surface 1317 is machined on the surface facing away from the limiting member 120. Due to the presence of the reset member 140, when the key 130 is in a natural state without being pressed by an external force, the first abutting surface 1314 abuts against the limiting member 120; when the user presses the keycap 132 and the key 130 moves towards the switch member 160 against the reset force of the reset member 140, the third abutting surface 1317 will gradually approach and press against the switch member 160 to trigger the switch member 160. After the user releases the key 130 in the pressed state, the reset member 140 drives the key shaft 131 to move axially along the first shaft hole 111, so that the first abutting surface 1314 contacts the limiting member 120, and the key 130 is reset. The limiting member 120 plays a role in limiting the other extreme position, preventing the key shaft 131 from detaching from the bracket 110.

[0038] On the one hand, in the above embodiment, the reset force of the reset member 140 is used to make the first abutting surface 1314 abut and cooperate with the limiting member 120, realizing the axial limitation of the key 130 to prevent the key 130 from coming out. There is no need to additionally provide limiting components such as buckles or screws, which simplifies the product structure and reduces the assembly complexity. On the other hand, the limiting member 120 is a fixed structure, and the first shaft section 1311 is the structure of the key shaft 131 itself. Compared with sleeving a snap spring on the key shaft 131 for limiting, the contact limitation between the first shaft section 1311 and the limiting member 120 can improve the stability in the limited state and reduce the risk of part detachment.

[0039] Preferably, the limiting member 120 is preferably a plate structure, and a plane parallel to the first abutting surface 1314 is formed on the side facing the first shaft section 1311, so that when the first shaft section 1311 abuts against the limiting member 120, the contact between the two is a surface contact, further improving the stability in the limited state.

[0040] In some embodiments, such as Figure 2 、 Figures 8 - 9 and Figures 12 - 13As shown, a groove 1316 is circumferentially provided on the key shaft 131 of the switch assembly. A sealing ring 133 is sleeved on the groove 1316, and the sealing ring 133 is sealingly connected to the inner wall of the first shaft hole 111. In this embodiment, the sealing ring 133 is sealingly connected to the inner wall of the first shaft hole 111 to prevent external liquid or dust from entering the interior of the assembly, protect the internal electronic components from contamination and damage, improve the protection level of the assembly, and be applicable to application scenarios requiring waterproof and dustproof. The presence of the sealing ring 133 enhances the connection stability between the key shaft 131 and the first shaft hole 111, reduces looseness or displacement caused by friction or vibration, and ensures the long-term reliability of the assembly. By providing the groove 1316 on the key shaft 131 and sleeving the sealing ring 133, the design of the sealing structure is simplified, and the complexity of production and assembly is reduced.

[0041] In some embodiments, such as Figures 2 - 3 , Figure 8 , Figures 11 - 12 As shown, a receiving groove 114 matching the outer shape of the keycap 132 is provided on one side of the bracket 110 of the switch assembly facing the keycap 132. The contour of the receiving groove 114 is adapted to the outer contour of the keycap 132. Specifically, the groove wall of the receiving groove 114 has a certain shape and size to ensure that the keycap 132 can move smoothly and stably along the axis during pressing and prevent deviation or skew. In the design of the receiving groove 114, the groove wall is closely fitted with the outer edge of the keycap 132, so that the keycap 132 will not swing or rub unnecessarily during pressing, thus ensuring the smoothness and comfort of the pressing action. In addition, the bottom of the receiving groove 114 is designed to have a certain depth to provide a limiting effect on the axial movement of the keycap 132 in the pressed state.

[0042] Specifically, during the pressing process of the keycap 132, it can move freely along the groove wall of the receiving groove 114, but during the pressing process, the amplitude of its axial movement is limited by the bottom of the receiving groove 114, preventing the keycap 132 from exceeding the set movement range. In this way, the limiting effect of the bottom of the groove effectively prevents the keycap 132 from moving excessively during pressing, thereby avoiding excessive extrusion of the key shaft 131 on the switch member 160 and causing damage, and ensuring the service life and stability of the switch member 160. That is, the receiving groove 114 not only enhances the cooperation stability between the keycap 132 and the bracket 110, but also realizes the movement limit of the keycap 132, avoiding the adverse effects of excessive pressing or uncontrolled movement of the keycap 132 on the internal switch member 160, and greatly improving the reliability and operation experience of the key 130.

[0043] In some embodiments, such as Figures 2 - 3 , Figure 8 and Figures 11 - 13As shown, the reset member 140 of the switch assembly is a spring disposed between the keycap 132 and the bracket 110. A third mounting groove 115 for mounting the spring is provided on one side of the bracket 110 facing the keycap 132. The working principle of this spring is to store mechanical energy. When the key 130 is pressed by an external force, it compresses and stores elastic potential energy. When the external force is removed, the spring releases the stored energy and pushes the key 130 back to its initial position, thus completing the reset action, enabling the key 130 to automatically reset to its initial state after the pressing is released. The design of the third mounting groove 115 allows the spring serving as the reset member 140 to maintain its correct position when the key 130 is pressed, preventing the spring from shifting in position or undergoing unnecessary deformation and maintaining a stable working state. Specifically, the shape and size of the third mounting groove 115 are adapted to the selected spring, and the groove wall can fit with the outer surface of the spring, thereby fixing the position of the spring and preventing it from shifting or excessively swaying during operation, and defining the elastic force direction parallel to the axial direction of the key axis 131. The depth of the third mounting groove 115 ensures that the spring can freely expand and compress during and after the keycap 132 is pressed to provide sufficient restoring force. The opening of the third mounting groove 115 not only provides a mounting position for the spring but also enables precise control of the position and force-bearing state of the spring, improving the stability of the reset function, avoiding possible damage or failure of the spring, and enabling it to maintain good performance during repeated pressing.

[0044] In some embodiments, as Figure 3 , Figure 9 and Figure 12 As shown, a limiting groove 1321 facing the third mounting groove 115 is provided on one side of the keycap 132 of the switch assembly facing the bracket 110. One end of the spring is limited within the limiting groove 1321, and the other end extends into the third mounting groove 115. The design of the limiting groove 1321 can effectively prevent the spring from tilting or undergoing radial displacement during operation, thereby avoiding uneven force on the spring, and further ensuring that the pressing and resetting processes of the keycap 132 are smooth and consistent, improving the service life and overall stability of the key 130. In addition, with the coordinated cooperation of the limiting groove 1321 and the third mounting groove 115, both ends of the spring are respectively limited and stably arranged through the corresponding third mounting groove 115 and limiting groove 1321, further avoiding problems such as uneven force on the keycap 132 or unsmooth operation of the key 130 caused by spring instability, and ensuring that the spring does not undergo radial displacement or tilt during operation.

[0045] In some embodiments, as Figure 2As shown in FIGS. 11 or 12, there are two sets of springs, third mounting grooves 115 and limiting grooves 1321 of the switch assembly, which are correspondingly arranged and symmetrically distributed on both sides of the key shaft 131. There is a set of third mounting groove 115 and limiting groove 1321 on each side of the key shaft 131, and both ends of the spring are respectively matched with these grooves. This design effectively avoids the eccentric force or asymmetric pressure that may be caused by the unilateral design, thereby enhancing the overall stability of the switch assembly. The springs symmetrically distributed on both sides maintain balance during the pressing and resetting processes of the key 130, avoiding the incomplete reset or insensitive pressing of the key 130 caused by uneven force on the springs. At the same time, such a design can also reduce the wear of components caused by uneven force.

[0046] In some embodiments, the limiting member 120 and the key 130 are both conductors, the bracket 110 is an insulator, and the limiting member 120 is configured to be electrically connected to the second circuit board 200. In this embodiment, the cooperation between the key 130 and the limiting member 120 can realize the function of conducting signals of the touch key 130. Specifically, in the above embodiment, the first abutting surface 1314 of the key 130 and the limiting member 120 participate in forming a conduction path. The key 130 is used for conducting electrical signals after being touched, and the limiting member 120 is used to be directly or indirectly connected to the circuit system of the electronic device, specifically, it can be electrically connected to the second circuit board 200, so as to transmit the touch electrical signal under the touch function to the circuit system. When the touch conduction function needs to be used, the user touches the outer surface of the key 130 with a finger, and the key 130 will not move. The first abutting surface 1314 and the limiting member 120 still remain in the abutting state. At this time, the key cap 132, the first abutting surface 1314, the limiting member 120, and the second circuit board 200 of the key 130 will participate in forming a first conduction path to transmit the touch electrical signal to the circuit system of the electronic device; when the pressing function needs to be used, the user applies a pressing force with a finger on the outer surface of the key 130, and the key 130 will overcome the restoring force of the restoring member 140 and move along the first shaft hole 111, and the moving direction is from the first side to the second side, so as to trigger the switch member 160 through the moved key 130 to realize the pressing trigger function. During this process, the first abutting surface 1314 and the limiting member 120 will be separated from each other, so that the first conduction path is cut off during the pressing process.

[0047] During the above working process, in the natural state and the touched state, the first abutting surface 1314 of the key 130 remains in an abutting state with the limiting member 120, and the limiting member 120 is clamped between the first shaft section 1311 and the bracket 110. The abutting force is provided by the reset member 140, without the need for the limiting member 120 itself to elastically deform to provide the abutting force. In the pressed state, the movement of the key 130 will not cause deformation of the limiting member 120. Instead, the first abutting surface 1314 of the key 130 will be separated from the limiting member 120. In this technical solution, whether in the touched usage scenario or the pressed usage scenario, the limiting member 120 for conducting electricity will not move or be structurally deformed, which will not cause fatigue accumulation of the limiting member 120 and improves the working life.

[0048] In some embodiments, the limiting member 120 in the switch assembly is adhesively connected to the bracket 110. A second shaft hole 121 is formed in the limiting member 120 opposite to the first shaft hole 111. The key shaft 131 includes a second shaft section 1312 passing through the second shaft hole 121. The first shaft section 1311 is connected to the second shaft section 1312 and the first abutting surface 1314 is formed at one end where the first shaft section 1311 is connected to the second shaft section 1312. The aperture of the second shaft hole 121 is smaller than the outer diameter of the first shaft section 1311 and larger than the outer diameter of the second shaft section 1312.

[0049] The adhesive connection between the limiting member 120 and the bracket 110 can achieve a tight fit between the limiting member 120 and the bracket 110, forming a firm and stable structure. The limiting member 120 can be adhesively fixed to the bracket 110 in various ways, such as by using screws, snap structures, hot pressing or gluing, etc., so that the limiting member 120 will not loosen or fall off during the entire use process of the key 130. Optionally, as Figure 2 、 Figures 6 - 8 、 Figure 10 and Figure 13 shown, the switch assembly further includes a fixing post 152. A second installation groove 113 is formed on one side of the bracket facing the limiting member 120. A first through hole 122 is formed in the limiting member 120 opposite to the second installation groove 113. The fixing post 152 passes through the first through hole 122 and is screwed into the second installation groove 113 to fix the limiting member 120 to the bracket 110, enhancing the structural stability of the assembly.

[0050] The contact surface between the limiting member 120 and the bracket 110 can be precisely machined to make its surface smoother and flatter, thereby increasing the contact area between the two and further enhancing the fixing effect. In this way, the limiting member 120 can effectively bear the axial force of the key 130.

[0051] On the fitting connection bracket 110 of the limiting member 120, under the restoring force of the restoring member 140, in the natural state, the first abutting surface 1314 of the first shaft section 1311 forms an abutting force with the side of the limiting member 120 away from the bracket 110, further enhancing the stability of the limiting member 120. This design not only ensures that the limiting member 120 is firmly fixed on the bracket 110, but also further improves the overall stability and durability of the assembly through the axial force transmission of the first shaft section 1311. The first abutting surface 1314 of the first shaft section 1311 forms a tight contact with the side of the limiting member 120 away from the bracket 110. This contact is not a simple supporting effect, but through the transmission of the axial force, the limiting member 120 is more firmly fixed on the bracket 110, preventing the limiting member 120 from shifting or loosening. Especially during the pressing process with a large force, the first abutting surface 1314 can effectively transmit the force evenly to the limiting member 120, and through the limiting member 120, transfer the pressure to the bracket 110 with a load-bearing function. During the repeated pressing and restoring processes, the limiting member 120 can rely on this additional abutting force to reduce the stress concentration caused by vibration or impact, so that the limiting member 120 is not easily damaged or worn during long-term use. Even under extreme or high-frequency working conditions, the key 130 and the limiting member 120 can still maintain good performance.

[0052] The aperture of the second shaft hole 121 is smaller than the outer diameter of the first shaft section 1311, which enables an effective abutting effect to be formed between the first shaft section 1311 and the limiting member 120. This design ensures that during the operation of the key 130, the contact between the first shaft section 1311 and the limiting member 120 can be maintained stably, thus effectively preventing the key 130 from being damaged or having unstable functions due to excessive movement. On the other hand, the aperture of the second shaft hole 121 is larger than the outer diameter of the second shaft section 1312. This design enables the key shaft 131 to axially move freely within the second shaft section 1312 without being interfered by the limiting member 120. That is to say, when the second shaft section 1312 passes through the second shaft hole 121, it can smoothly perform axial movement, ensuring the normal pressing and restoring functions of the key 130. Through this structure, the axial movement range of the key 130 is effectively controlled, while ensuring the smooth operation of the key 130, avoiding the problem of unsmooth operation of the key 130 caused by excessive friction or unsmooth movement.

[0053] In this embodiment, by ingeniously designing the size of the second shaft hole 121 of the limiting member 120, the balance between the key shaft 131 being limited and movable is ensured. The key shaft 131 can effectively contact the limiting member 120 when the button 130 is reset to limit the button 130, and can also maintain axial free movement during normal pressing use, ensuring the stability of the button 130 and the comfort of operation. This design not only improves the durability of the switch assembly, but also optimizes the user experience, ensuring that the button 130 responds sensitively and is reliable in the long term.

[0054] In some embodiments, the aperture of the first shaft hole 111 in the switch assembly is larger than the maximum outer diameter of the key shaft 131, and the second shaft hole 121 penetrates through to the edge of the limiting member 120 to form a notch 123 as shown in Figure 7 . The aperture of the first shaft hole 111 being larger than the maximum outer diameter of the key shaft 131 can ensure that the key shaft 131 can smoothly penetrate through the entire first shaft hole 111. The maximum outer diameter of the key shaft 131 is slightly smaller than the aperture of the first shaft hole 111, which not only allows the key shaft 131 to freely insert from the first side of the bracket 110, but also ensures that during the installation of the button 130, the first shaft section 1311 can protrude from the second side. The free movement of the key shaft 131 in the first shaft hole 111 ensures the smooth movement of the button 130 assembly, avoiding problems of blockage or jamming caused by the first shaft hole 111 being too small.

[0055] Since the first shaft section 1311 will abut against the limiting member 120 during operation, the first shaft section 1311 will inevitably not be able to penetrate through the second shaft hole 121 of the limiting member 120. How to quickly sleeve the second shaft hole 121 onto the key shaft 131 during the assembly process has become an urgent problem to be solved. As shown in Figure 10 , in this embodiment, making the second shaft hole 121 penetrate through to the edge of the limiting member 120 to form a notch 123 can achieve the detachable assembly of the button 130, the bracket 110, and the limiting member 120. Through this notch 123, the limiting member 120 during the assembly process can move radially, enabling the second shaft hole 121 of the limiting member 120 to be sleeved onto the second shaft section 1312 of the key shaft 131, instead of passing through the second shaft hole 121 in the axial movement manner. This design greatly simplifies the installation steps of the limiting member 120 and enhances the convenience of later maintenance and replacement by providing detachability.

[0056] A specific assembly process is schematically illustrated as follows.

[0057] Step 1: The key shaft 131 of the key 130 is inserted into the first shaft hole 111 from the first side of the bracket 110, and the first shaft segment 1311 is continuously extended from the second side of the bracket 110. At this time, the limiting member 120 has not been installed on the bracket 110, and the first shaft segment 1311 can freely extend to the second side of the bracket 110 and is completely exposed outside the bracket 110, and a part of the second shaft segment 1312 is also exposed outside the bracket 110.

[0058] Step 2: Install the limiting member 120. At this time, the notch 123 on the limiting member 120 is close to the second shaft segment 1312, and the limiting member 120 is radially moved through the notch 123 communicated with the second shaft hole 121 on the limiting member 120, so that the second shaft hole 121 is sleeved on the second shaft segment 1312.

[0059] Step 3: Fix the limiting member 120 to ensure that the limiting member 120 is firmly connected to the bracket 110.

[0060] During the above assembly process, no complex tools or high-precision operations are required, which is convenient for production and assembly. The design of the notch 123 communicated with the second shaft hole 121 enables the limiting member 120 to be easily assembled and disassembled, which is very important for later maintenance and replacement, especially in the case where electronic products need to be used for a long time or frequently repaired. By designing a reasonable aperture fit and shaft segment limiting structure, the deviation or misoperation that may occur during the assembly process is avoided, ensuring the accurate fit of each component, thereby improving the overall reliability and stability of the product.

[0061] In some embodiments, such as Figure 2 and 12As shown in the figure, the switch assembly further includes an auxiliary conductive structure 150. When the first abutting surface 1314 is disengaged from the limiting member 120, the button 130 is electrically connected to the limiting member 120 through the auxiliary conductive structure 150. When the touch conduction function is required, the user touches the outer surface of the button 130 with a finger, and the button 130 will not move. The first abutting surface 1314 and the limiting member 120 still remain in the abutting state. At this time, the human body, the first abutting surface 1314 of the button 130, and the limiting member 120 will form a first conduction path to transmit the touch electrical signal to the circuit system of the electronic device. When the pressing function is required, the user applies a pressing force on the outer surface of the button 130 with a finger. The button 130 will overcome the restoring force of the restoring member 140 and move along the first shaft hole 111. The displacement direction is from the first side to the second side, so as to trigger the corresponding controlled component through the moved button 130 to achieve the pressing trigger function. During this process, the first abutting surface 1314 and the limiting member 120 will be disengaged from each other, so that the first conduction path cannot be realized during the pressing process. In order to enable the button 130 to realize the touch conduction function while realizing the pressing trigger function, in this embodiment, when the first abutting surface 1314 is disengaged from the limiting member 120, the button 130 is electrically connected to the limiting member 120 through the auxiliary conductive structure 150, that is, the human body, the button 130, the auxiliary conductive structure 150, and the limiting member 120 will form a second conduction path to transmit the touch electrical signal to the circuit system of the electronic device. When the user no longer presses the button 130, the button 130 will be reset to the natural state under the action of the restoring member 140, and the first abutting surface 1314 and the limiting member 120 will abut again.

[0062] In the above working process, in the natural state and the touch state, the first abutting surface 1314 of the button 130 and the limiting member 120 remain in the abutting state, and the limiting member 120 is clamped between the first shaft section 1311 and the bracket 110. The abutting force is provided by the restoring member 140, and there is no need for the limiting member 120 itself to undergo elastic deformation to provide the abutting force. In the pressing state, the movement of the button 130 will not cause the deformation of the limiting member 120. Instead, the first abutting surface 1314 of the button 130 and the limiting member 120 will be disengaged from each other. In this technical solution, whether in the touch usage scenario or in the pressing usage scenario, the limiting member 120 will not move and its structure will not deform, which will not cause fatigue accumulation of the limiting member 120 and improves the working life. In addition, in the above embodiment, the abutting state between the first abutting surface 1314 and the limiting member 120 can prevent the key shaft 131 of the button 130 from disengaging from the first shaft hole 111, and there is no need to additionally provide other anti-disengagement limiting structures.

[0063] In summary, the switch assembly provided in this embodiment has at least the following four key design advantages.

[0064] First, the limiting member 120 has zero deformation. In the natural state, the touch state, and the pressing process, the limiting member 120 only serves as a static contact surface or a non-contact structure and does not need to undergo elastic deformation, greatly eliminating the risk of fatigue failure.

[0065] Second, double touch signal path guarantee. The button 130 in the touch state is directly conducted with the limiting member 120 through the first abutting surface 1314, and the button 130 in the pressing state is conducted with the limiting member 120 through the auxiliary conductive structure 150, ensuring the stable operation of the touch function throughout the entire operation cycle.

[0066] Third, self-limiting structure simplification. The elastic force of the reset member 140 is used to make the first abutting surface 1314 abut and cooperate with the limiting member 120, realizing the axial limitation of the button 130 to prevent the button 130 from coming out. There is no need to additionally set limiting components such as buckles or screws, reducing the assembly complexity.

[0067] Fourth, the reset member 140 independently bears mechanical stress, and the limiting member 120 only transmits touch electrical signals. The two functions are separated and each performs its own duties, significantly improving the overall reliability and service life of the component.

[0068] It should be noted that in the above embodiments, the limiting member 120 and the button 130 are both conductors, and the bracket 110 is an insulator.

[0069] In some embodiments, such as Figure 2 、 Figures 6 - 8 shown, the auxiliary conductive structure 150 includes a first spring 151 and the fixed column 152 mentioned in the previous embodiment. Of course, in this embodiment, the fixed column 152, the button 130, and the limiting member 120 are all conductors. The first end of the first spring 151 is connected to the side of the keycap 132 facing the bracket 110, and the fixed column 152 is connected to the limiting member 120 and extends into the bracket 110; when the first abutting surface 1314 is disengaged from the limiting member 120, the second end of the first spring 151 abuts against the fixed column 152. The keycap 132 is used as the operating end of the button 130 and can be touched and pressed by the user. At least part of the keycap 132 is exposed outside the bracket 110 for the user to touch or press.

[0070] The above embodiments provide a specific implementation of the auxiliary conductive structure 150, that is, the auxiliary conductive structure 150 includes a first spring 151 and a fixing post 152. During the pressing process of the key 130, the first spring 151 can contact the fixing post 152 to form a second conduction path composed of the keycap 132, the first spring 151, the fixing post 152, and the limiting member 120, so as to transmit the touch electrical signal to the circuit system of the electronic device. After the key 130 is released, the elastic force of the reset member 140 will cause the key 130 to return to its natural state, ensuring that the first abutting surface 1314 contacts the limiting member 120 again.

[0071] In this implementation, first, the auxiliary conductive structure 150 selects the cooperation mode of the first spring 151 and the fixing post 152. The limiting member 120 will not deform during the natural state, touch state, and movement process of the key 130, ensuring the elimination of the risk of fatigue failure of the limiting member 120 and improving its service life. Secondly, the cooperation of the first spring 151 and the fixing post 152 in the auxiliary conductive structure 150 in this implementation can participate in forming the second conduction path, ensuring the realization of the transmission of the touch signal in the pressed state and ensuring the stable operation of the touch function in the pressed state. Thirdly, due to the deformable property of the first spring 151, the pressing process of the key 130 can continue after the first spring 151 abuts against the fixing post 152, and the auxiliary conductive structure 150 will not prevent the pressing displacement of the key 130, ensuring that the displacement of the key 130 can trigger the corresponding components. In addition, the design of the first spring 151 and the fixing post 152 selected for the auxiliary conductive structure 150 is simple, which simplifies the structure of the touch and press dual-purpose key, improves the reliability, and reduces the production cost at the same time.

[0072] Based on the above implementation, as Figure 2 and 11 shown, a first installation groove 112 is formed on one side of the bracket 110 facing the keycap 132, a second installation groove 113 is formed on one side of the bracket 110 facing the limiting member 120, the first installation groove 112 communicates with the second installation groove 113, the first spring 151 extends into the first installation groove 112, and the fixing post 152 extends into the second installation groove 113.

[0073] With this design, the first spring 151 and the fixing post 152 are respectively fixed in two different directions of the bracket 110, so that they can stably cooperate with other components and ensure the stability of the switch component during the pressing of the button 130. Specifically, the design of the first mounting groove 112 and the second mounting groove 113 allows the first spring 151 and the fixing post 152 to maintain their respective correct positions when the button 130 is pressed, avoiding their position deviation or unnecessary deformation. The first mounting groove 112 communicates with the second mounting groove 113 to ensure that the first spring 151 and the fixing post 152 can achieve physical contact connection. A second conduction path is formed through the fixing post 152 and the limiting member 120 to transmit the touch electrical signal to the circuit system of the electronic device.

[0074] The fixing post 152 not only serves as a fixing member to firmly fix the limiting member 120 on the bracket 110, but also participates in the signal transmission of the second conduction path. The fixing post 152 is screwed to cooperate with the second mounting groove 113, ensuring the stability of signal transmission while guaranteeing the mechanical connection between the limiting member 120 and the bracket 110, and enhancing the structural stability of the component. When the button 130 is in the pressed state, the fixing post 152 contacts the second end of the first spring 151 and participates in forming the second conduction path to continue transmitting the touch signal to the circuit system. Since the fixing post 152 also plays a role in the fixed installation of the limiting member 120, its design ensures the structural stability and avoids the loosening or displacement of the limiting member 120 during long-term use. That is, the fixing post 152 not only solves the problem of the conduction path, but also takes into account the fixing problem of the limiting member 120, simplifies the structural design, improves the reliability, and reduces the need for additional fixing members.

[0075] As a first mating form of the first spring 151 and the fixed post 152, in some embodiments, the end of the fixed post 152 extends into the first mounting groove 112. When the first abutting surface 1314 contacts the limiting member 120, the second end of the first spring 151 is separated from the fixed post 152. In this way, in the non-pressed state (including the natural state and the touch state), only the first conduction path works, and the second conduction path is not activated because the first spring 151 and the fixed post 152 cannot be connected. Specifically, when the button 130 is in the natural state or the touch state, the first conduction path contacts the limiting member 120 through the first abutting surface 1314 and transmits the touch signal to the circuit system of the electronic device. At this time, the second conduction path is in a non-working state because the second end of the first spring 151 does not contact the fixed post 152, so an effective circuit connection cannot be formed. When the user presses the button 130, the first abutting surface 1314 is separated from the limiting member 120, and the first conduction path is interrupted. At this time, the second end of the first spring 151 gradually approaches the fixed post 152 and finally achieves contact and cooperation with the fixed post 152, thereby forming the second conduction path. At this time, the second conduction path is activated and continues to work to ensure that the touch signal can still be transmitted in the pressed state.

[0076] Through the switching of the first conduction path and the second conduction path, this design can selectively activate the first conduction path or the second conduction path, ensuring the stability and flexibility of touch signal transmission in the pressed and non-pressed states. In the non-pressed state, only the first conduction path works and the second conduction path does not work, effectively avoiding unnecessary signal transmission interference and keeping the touch signal pure. Through the ingenious design of the fixed post 152 and the first mounting groove 112, the smooth operation of the button 130 in different states is ensured, and the reliability of the overall structure is improved.

[0077] In this embodiment, in the non-pressed state, only the first conduction path works. When the pressed state is started, the first conduction path is interrupted, and the second conduction path continues to work through the contact between the first spring 151 and the fixed post 152. It can be applied to the following working scenarios.

[0078] Scenario a: Applicable to devices that need to switch operation function modes. For example, in a smart watch or a sports bracelet, the touch signal (the first conduction path) in the touch state is used for basic first function operations, while the touch signal (the second conduction path) in the pressed state is used to trigger a second different function operation, such as activating the setting interface or turning on a special function. At this time, the transmission of the touch signal of the first conduction path is disconnected at the beginning of pressing, and the second conduction path has not been activated, which can effectively avoid accidental touch and unnecessary operations and realize the switching of two touch functions.

[0079] Scenario b: Applicable to low-power devices, such as certain portable audio players and simple remote controls. In the non-pressing state, the touch signal is transmitted through the first conduction path, while in the pressing state, the touch signal is transmitted through the second conduction path. While enabling the transmission of touch information in both states, it does not consume excessive power.

[0080] Scenario c: Applicable to electronic devices with extremely high requirements for signal interference. If the first conduction path and the second conduction path are both in the working state simultaneously, signal transmission between them may be asynchronous. In the non-pressing state, the second conduction path does not work, effectively avoiding unnecessary signal transmission interference and maintaining the purity of the touch signal.

[0081] As a second form of cooperation between the first spring 151 and the fixed column 152, in some embodiments, the end of the fixed column 152 of the switch assembly extends into the first mounting groove 112. When the first abutting surface 1314 contacts the limiting member 120, the second end of the first spring 151 abuts against the fixed column 152. In this embodiment, in the non-pressing state (including the natural state and the touch state), both the first conduction path and the second conduction path are in the activated state. Specifically, when the button 130 is in the natural state or the touch state, the first conduction path contacts the limiting member 120 through the first abutting surface 1314 and transmits the touch signal to the circuit system of the electronic device. At this time, the second conduction path abuts against the fixed column 152 through the second end of the first spring 151 and transmits the touch signal to the circuit system of the electronic device, forming an effective electrical connection. When the user presses the button 130, the first abutting surface 1314 is separated from the limiting member 120, and the first conduction path is interrupted. At this time, after the first spring 151 is compressed and deformed, its second end can more stably abut against the fixed column 152, and the second conduction path still continues to work, ensuring that the touch signal can still be transmitted in the pressing state.

[0082] This design enables both the first conduction path and the second conduction path to work in the non-pressing state. After the pressing action is initiated, the button 130 and the limiting member 120 are always in a connected state, and the second conduction path is always in the working state. During the switching process between the touch and pressing actions, there will be no breakpoints in the touch signal transmission of the component.

[0083] In the non-pressing state of this embodiment, both the first conduction path and the second conduction path are working. When the pressing action is initiated, the first conduction path is interrupted, and the second conduction path continues to work, ensuring that the button 130 and the limiting member 120 are always connected. This is particularly applicable to scenarios where stable and continuous touch signal transmission is required, especially for devices that frequently switch operation modes, ensuring that touch signals can operate stably during high-frequency pressing interactions, enabling the device to process pressing actions without stopping touch signal transmission. Specific usage scenarios are exemplified as follows.

[0084] Scenario d: When the smartwatch performs medical monitoring functions, touch signals are used to monitor physical health parameters, and pressing operations are used to physically trigger other functions, such as display operations or menu selections, etc. During the pressing process, it is necessary to maintain the continuous transmission of touch signals to continuously monitor physical health parameters. By adopting this embodiment, touch signals and pressing signals work in parallel, which can ensure that the transmission of touch signals is not interrupted during the pressing process.

[0085] Scenario e: When applied to game control devices (such as gamepads), rapid and frequent switching between touch and pressing actions is required, and it is necessary to ensure the continuous transmission of touch signals during the switching process without interrupting the game operations corresponding to the touch signals, providing an efficient operation experience.

[0086] It should be noted that the applicability of the above two specific cooperation forms of the first spring 151 and the fixed column 152 depends on the usage scenario of the electronic device and the requirements of the specific operation mode. Those skilled in the art can make adaptive adjustments and selections according to needs.

[0087] In some usage scenarios, when the button 130 of the switch component is pressed, it is only to achieve the physical trigger function and does not need to achieve the transmission of touch signals. In order to be able to be compatible with this usage scenario through a set of component structures, the technicians further make the following improvements: The fixed column 152 is screwed and matched with the first through hole 122 and / or the second installation groove 113. During the process of rotating the fixed column 152, the end of the fixed column 152 has a state located in the first installation groove 112 and a state located in the second installation groove 113.

[0088] In this embodiment, by rotating the fixing post 152, a technician can adjust the position of its end according to needs. The fixing post 152 can be screwed to flexibly position its end in the first installation groove 112 or the second installation groove 113. This design enables the fixing post 152 to selectively activate the second conduction path when the button 130 is in the pressed state. Specifically, when the end of the fixing post 152 is located in the second installation groove 113, the end of the first spring 151 located in the first installation groove 112 cannot extend into the second installation groove 113 to connect with the fixing post 152, so that the second conduction path is not activated, and only the physical operation of the button 130 is triggered when pressed; on the contrary, when the end of the fixing post 152 rotates into the first installation groove 112, the end of the first spring 151 located in the first installation groove 112 can be in abutting cooperation with the fixing post 152, and the second conduction path can be activated. When pressed, not only the physical trigger function of the button 130 is achieved, but also the touch signal can be transmitted through the second conduction path to continue to achieve the touch conduction function. By rotating the fixing post 152, the working mode of the switch component can be flexibly selected according to actual needs, allowing different functional requirements to be realized within the same component. It can not only simplify the design and reduce unnecessary functions, but also enhance functions according to needs, making the device compatible with different usage scenarios, enhancing the adaptability and customizability of the switch component. And this design uses screw rotation adjustment, does not require additional complex switches or adjustment mechanisms, saves design and installation space, and at the same time maintains the stability of the function of the button 130. As the usage scenarios and requirements of the device are constantly changing, a technician can adjust the position of the fixing post 152 according to the specific usage scenario of the device for flexible configuration, so that the component can be widely applied to different products.

[0089] The rotation function of the fixing post 152 can be achieved by screwing only with the first through hole 122, by screwing only with the second installation groove 113, or by simultaneously screwing with the first through hole 122 and the second installation groove 113. The last method is preferably adopted. At this time, the fixing post 152 is screwed to both the first through hole 122 and the second installation groove 113. On the basis of achieving the foregoing technical effects, the technical effect of fixing the limiting member 120 on the bracket 110 can also be achieved simultaneously.

[0090] It should be noted that as Figure 2 、 Figure 8 and Figure 11 shown, those skilled in the art can use one of the springs used as the reset member 140 as the first spring 151 according to needs, so that while realizing the reset function, it can cooperate with the fixing post 152 to form the first conduction path. Similarly, the third installation groove 115 for accommodating the spring of the reset member can be used as the first installation groove 112 for accommodating the first spring 151.

[0091] In some embodiments, as Figure 9 shown, the key shaft 131 of the switch assembly includes a first shaft section 1311, a second shaft section 1312, and a third shaft section 1313. The first shaft section 1311, the second shaft section 1312, and the third shaft section 1313 are arranged in sequence. The second shaft hole 121 is sleeved outside the second shaft section 1312. One end of the first shaft section 1311 facing the limiting member 120 protrudes radially from the second shaft section 1312 to form a first abutting surface 1314. One end of the third shaft section 1313 facing the limiting member 120 protrudes radially from the second shaft section 1312 to form a second abutting surface 1315. In this embodiment, the key shaft 131 of the switch assembly is formed by sequentially arranging the first shaft section 1311, the second shaft section 1312, and the third shaft section 1313, forming a multi-section structure. In the natural state or when the user touches the key 130, the first abutting surface 1314 contacts the limiting member 120 and participates in forming a first conduction path to transmit the touch signal to the circuit system of the electronic device. At this time, the second conduction path is not activated. When the user presses the key 130, the first abutting surface 1314 disengages from the limiting member 120, and the first conduction path is interrupted. The second abutting surface 1315 will gradually approach and contact one side of the limiting member 120 facing the bracket 110, thereby forming a second conduction path composed of the key 130, the second abutting surface 1315 of the key 130, and the limiting member 120, and continuing to transmit the touch signal to the circuit system to ensure the transmission of the touch signal in the pressed state. That is, at this time, the second abutting surface 1315 functions as the auxiliary conductive structure 150.

[0092] It is not difficult to find that in the above embodiments, the second abutting surface 1315 is the limiting surface at the extreme position of the movement of the key 130 in the pressed state. That is, after the second abutting surface 1315 abuts against the limiting member 120, the key 130 is blocked by the limiting member 120 and cannot move further. At this time, only when the key 130 moves to the extreme position can the second conduction path be activated. The conditions are too harsh, which limits the applicability of the switch assembly. Based on this, as Figure 12 shown, on the basis of the above embodiments, the auxiliary conductive structure 150 includes a second spring 153 sleeved on the second shaft section 1312. The first end of the second spring 153 is connected to the second abutting surface 1315. After the first abutting surface 1314 disengages from the limiting member 120, the second end of the second spring 153 can abut against one side of the limiting member 120 facing the key cap 132.

[0093] The above embodiments provide another specific implementation of the auxiliary conductive structure 150, that is, the auxiliary conductive structure 150 includes a second spring 153. During the pressing process of the key 130, the second spring 153 can contact the limiting member 120 to form a second conduction path composed of the keycap 132, the second abutting surface 1315, the second spring 153, and the limiting member 120, thereby transmitting the touch electrical signal to the circuit system of the electronic device. After the key 130 is released, the elastic force of the reset member 140 will cause the key 130 to return to its natural state, ensuring that the first abutting surface 1314 contacts the limiting member 120 again.

[0094] In this embodiment, first, the auxiliary conductive structure 150 selects the second spring 153 to cooperate with the limiting member 120. The limiting member 120 will not deform during the natural state, touch state, and movement process of the key 130, ensuring the elimination of the risk of fatigue failure of the limiting member 120 and improving its service life. Secondly, the cooperation between the second spring 153 and the limiting member 120 in the auxiliary conductive structure 150 in this embodiment can participate in forming a second conduction path, ensuring the transmission of the touch signal in the pressed state and the stable operation of the touch function in the pressed state. Thirdly, due to the deformable property of the second spring 153, the pressing process of the key 130 can continue after the second spring 153 abuts against the limiting member 120. The limiting member 120 and the auxiliary conductive structure 150 will not prevent the pressing displacement of the key 130, ensuring that the displacement of the key 130 can trigger the corresponding components. With the deformability of the second spring 153, the second conduction path can be activated during part or all of the stroke when the key 130 is pressed. In addition, the design of the auxiliary conductive structure 150 using the second spring 153 has a simple structure, simplifies the structure of the touch and press dual-purpose key, improves the reliability, and reduces the production cost at the same time.

[0095] As the first cooperation form between the second spring 153 and the stopper 120, in some embodiments, when the first abutting surface 1314 contacts the stopper 120, the second end of the second spring 153 is separated from the stopper 120. In this way, in the non-pressing state (including the natural state and the touch state), only the first conduction path works, and the second conduction path is not activated because the second spring 153 and the stopper 120 cannot be connected. Specifically, when the key 130 is in the natural state or the touch state, the first conduction path contacts the stopper 120 through the first abutting surface 1314 and transmits the touch signal to the circuit system of the electronic device. At this time, the second conduction path is in a non-working state because the second end of the second spring 153 does not contact the stopper 120, so an effective circuit connection cannot be formed. When the user presses the key 130, the first abutting surface 1314 is separated from the stopper 120, and the first conduction path is interrupted. At this time, the second end of the second spring 153 gradually approaches the stopper 120 and finally realizes the contact cooperation with the stopper 120, thereby forming the second conduction path. At this time, the second conduction path is activated and continues to work to ensure that the touch signal can still be transmitted in the pressing state.

[0096] Through the switching between the first conduction path and the second conduction path, this design can selectively activate the first conduction path or the second conduction path, ensuring the stability and flexibility of touch signal transmission in both the pressing and non-pressing states. In the non-pressing state, the second conduction path does not work, effectively avoiding unnecessary signal transmission interference and keeping the touch signal pure. In this embodiment, only the first conduction path works in the non-pressing state. When the pressing state is started, the first conduction path is interrupted, and the second conduction path continues to work through the contact between the second spring 153 and the stopper 120. It can also be applied to the working scenarios a, b, and c described above, which will not be elaborated here.

[0097] As a second cooperation form between the second spring 153 and the limiting member 120, in some embodiments, when the first abutting surface 1314 contacts the limiting member 120, the second end of the second spring 153 abuts against the limiting member 120. In this embodiment, in the non-pressing state (including the natural state and the touch state), both the first conduction path and the second conduction path are in the activated state. Specifically, when the key 130 is in the natural state or the touch state, the first conduction path contacts the limiting member 120 through the first abutting surface 1314 and transmits the touch signal to the circuit system of the electronic device. At this time, the second conduction path abuts against the limiting member 120 through the second end of the second spring 153 and transmits the touch signal to the circuit system of the electronic device, forming an effective circuit connection. When the user presses the key 130, the first abutting surface 1314 is separated from the limiting member 120, and the first conduction path is interrupted. At this time, after the second spring 153 is compressed and deformed, its second end can abut more stably against the limiting member 120, and the second conduction path still continues to work, ensuring that the touch signal can still be transmitted in the pressing state. This design enables both the first conduction path and the second conduction path to work in the non-pressing state. After the pressing action is started, the key 130 and the limiting member 120 are always in a connected state, and the second conduction path is always in a working state. During the switching process between the touch and pressing actions, there will be no breakpoints in the touch signal transmission of the component.

[0098] In this embodiment, in the non-pressing state, both the first conduction path and the second conduction path work. When the pressing action is started, the first conduction path is interrupted, and the second conduction path continues to work, ensuring that the key 130 and the limiting member 120 are always connected. It is especially suitable for scenarios that require stable and continuous touch signal transmission, especially for devices that frequently switch operation modes, ensuring that the touch signal can operate stably in high-frequency pressing interactions, so that the device can process the pressing action without stopping the touch signal transmission. For specific examples of usage scenarios, reference can be made to the descriptions of scenarios d and e in the previous text, which will not be elaborated here.

[0099] In some embodiments, such as Figures 6 - 8 , Figure 10 , Figure 13As shown, the limiting member 120 includes a first limiting piece 124 and a second limiting piece 125 which are arranged at an angle. The first limiting piece 124 is fixed on the bracket 110; the button 130 is movably arranged on the bracket 110 to achieve contact with or separation from the first limiting piece 124. The second limiting piece 125 is used to be connected to the second circuit board 200 through a conductive connection member. During the movement of the button 130 relative to the bracket 110, there is a state of contact with the first limiting piece 124. At this time, after touching the touch button 130, the touch electrical signal is sequentially transmitted through the button 130, the first limiting piece 124, the second limiting piece 125, and the conductive connection member 700 to form a first conduction path, and then the touch signal can be transmitted to the second circuit board 200. In the related art, the conductive connection member usually uses a conductive elastic sheet. The conductive elastic sheet usually includes a fixing portion and an elastic portion. The fixing portion is used to be fixedly connected to structures such as a circuit board to realize the connection with its internal circuit, and the elastic portion is used for non-fixed pressing connection with an external circuit. Specifically, the elastic portion completes the contact with the external circuit depending on the deformation amount of the elastic portion. When the conductive elastic sheet is installed, an external force is required to deform the elastic portion to obtain sufficient elastic force so that the elastic portion can stably press and contact the external circuit. However, in the related art, the elastic portion of the conductive elastic sheet is in an undeformed state in the natural state before installation, and during the installation process, the undeformed elastic portion in the natural state needs to be adjusted to a deformed state with sufficient elastic force. This process requires a large deformation amount of the elastic portion, resulting in a cumbersome operation process. Based on this, the embodiment of the present application also provides an optimized conductive connection member.

[0100] As Figures 14 - 16As shown in the figure, the main structure of the conductive connector 700 provided by the embodiment of the present application includes a first substrate 710, wing plates 720, and an elastic sheet 730. The back surface of the first substrate 710 is configured to be connected to a circuit board. In this example, the connection between the back surface of the first substrate 710 and the second circuit board 200 is taken as an example for illustration. There are two wing plates 720, which are respectively formed by extending from the opposite sides of the first substrate 710 to the front side of the first substrate 710. The free end of one wing plate 720 is bent toward the other wing plate 720 to form a first limiting portion 740. The elastic sheet 730 includes a vertical plate 731, a first elastic arm 732, a bending section 733, and a second elastic arm 734 arranged in sequence. The vertical plate 731 is connected to the first substrate 710. The bending section 733 is located at the end of the elastic sheet 730 away from the first substrate 710 and protrudes from the free end of the wing plate 720. The second elastic arm 734 extends from the bending section 733 toward the first substrate 710 and extends into the space between the two wing plates 720. A second limiting portion 750 is formed on the second elastic arm 734. The second limiting portion 750 abuts against the side of the first limiting portion 740 facing the first substrate 710, so that the elastic sheet 730 is in a deformed state. The restoring force generated by the elastic sheet 730 makes the second limiting portion 750 always tend to move away from the first substrate 710.

[0101] The first substrate 710 is the core component of the conductive connector 700. Through the connection of its back surface with the second circuit board 200, electrical connection is completed, ensuring the stability and reliability of the connection between the conductive connector 700 and the second circuit board 200.

[0102] The design of the wing plates 720 not only enhances the structural stability but also, through its cooperation with the elastic sheet 730, ensures that the elastic sheet 730 can maintain a preset deformed state in the natural state.

[0103] The vertical plate 731 in the elastic sheet 730 is connected to the first substrate 710, playing a role of support and connection. The first elastic arm 732 is connected to the vertical plate 731 and has elasticity, responsible for providing the deformation ability for the elastic sheet 730 during the installation process. The bending section 733 is located at the end of the elastic sheet 730 away from the first substrate 710 and protrudes from the free end of the wing plate 720. It is used to contact and connect with the devices of the external circuit structure. The bending section 733 enables the conductive connector 700 to achieve electrical contact with the external circuit (such as sensors, connectors, conductive components, etc.). The second elastic arm 734 extends from the bending section 733 toward the first substrate 710 and enters the space between the wing plates 720, used to abut against the front surface of the first substrate 710 and deform when necessary, providing further elastic force.

[0104] A second limiting portion 750 is formed on the second elastic arm 734 of the elastic sheet 730. The second limiting portion 750 cooperates with the first limiting portion 740 on the wing plate 720. Through this cooperation, the elastic sheet 730 is in a preset deformed state in its natural state, ensuring that the elastic sheet 730 remains in a stable elastic state without external force.

[0105] The design of this embodiment enables the elastic sheet 730 to be maintained in a preset deformed state in its natural state through the cooperation of the first limiting portion 740 and the second limiting portion 750. During the installation process, only a small amount of deformation needs to be applied to further deform the elastic sheet 730 to a suitable position. The specific installation steps are as follows: Step 1, align the conductive connector 700 with a predetermined position on the second circuit board 200 so that the back surface of the first substrate 710 forms a stable connection with the second circuit board 200. At this time, due to the cooperation of the first limiting portion 740 and the second limiting portion 750, the elastic sheet 730 is already in a preset deformed state; Step 2, apply an external force to the elastic sheet 730 to further slightly deform the elastic sheet 730, causing the second limiting portion 750 to disengage from the first limiting portion 740 and approach the first substrate 710, so that the bent section 733 of the elastic sheet 730 gradually approaches the first substrate 710 to obtain the final installation state. After the elastic sheet 730 undergoes a slight deformation in the second step, it can form a stable abutment with the external structure through the bent section 733, ensuring reliable electrical connection of the conductive connector 700.

[0106] Through the cooperation of the first limiting portion 740 and the second limiting portion 750 in this embodiment, the elastic sheet 730 is maintained in a preset deformed state in its natural state. Only by adjusting the elastic sheet 730 to further undergo a smaller deformation amount can the required elastic abutting force be obtained. Compared with the elastic sheet 730 that is unconstrained in its natural state, the deformation adjustment amount during the installation process is smaller, reducing the operation steps that require a large deformation amount in the traditional technology, making the installation process more simple and efficient. And because the elastic sheet 730 is already maintained in a suitable deformed state in its natural state, the deformation amount during the installation process is smaller, thereby reducing the repeated bending and deformation adjustment range of the material and extending the service life of the conductive connector 700.

[0107] As the size of electro-conductive products is getting smaller and smaller, the integration of their internal structures is also increasing. This means that the operable space inside the product is becoming increasingly limited, and the need for external tools and large adjustments needs to be minimized during the installation process. Traditional installation methods often require a large amount of deformation or external force to complete the installation, while this embodiment ensures that the elastic sheet 730 is already in a preset deformation state in a natural state through the cooperation of the first limiting portion 740 and the second limiting portion 750. Only by applying external force can the elastic sheet 730 be further slightly deformed and installed, without the need for large-scale deformation and adjustment, thus avoiding the situation in which a large amount of space is required for operation in the traditional installation method. In order to adapt to the trend of various existing electronic products towards miniaturization and thinness, the design of the conductive connector 700 not only needs to ensure the stability of the electrical connection, but also fully considers the compactness of the internal structure of the conductive electronic product and the scene use requirements of the integration. Therefore, the traditional installation method often faces the problems of small space and inconvenient operation. This embodiment meets these new requirements by optimizing the deformation adjustment method of the elastic sheet 730.

[0108] In some embodiments, as shown in the figure, the vertical plate 731 of the conductive connector 700 is connected to the first elastic arm 732 through a continuously arranged first bending segment 735 and a second bending segment 736, and the bending directions of the first bending segment 735 and the second bending segment 736 are opposite.

[0109] The reverse bending design of the first curved section 735 and the second curved section 736 which are continuously arranged can effectively disperse the deformation stress, so that the elastic sheet 730 can be more evenly subjected to the external force during the working process. Compared with the traditional design, the continuous reverse bending setting allows the elastic sheet 730 to achieve ideal deformation under the action of a smaller force, thereby enhancing the overall elastic performance. The opposite bending directions of the first curved section 735 and the second curved section 736 provide elastic forces that oppose each other, which not only enables the elastic sheet 730 to maintain a certain flexibility under different deformation degrees, but also optimizes the deformation response of the elastic sheet 730, which is conducive to enhancing the deformation ability and reset ability of the conductive connector 700. The deformation force during the installation process is small, and the elastic sheet 730 can quickly return to the initial state where the first limit portion 740 and the second limit portion 750 abut against each other after the external force is removed.

[0110] In some embodiments, as shown in the figure, a protruding ear plate 760 is formed on the wing plate 720 of the conductive connector 700, and the ear plate 760 shields the first bending section 735 and / or the second bending section 736. Since the bending section is usually the part of the elastic sheet 730 most prone to fatigue damage, especially during high-frequency deformation or installation, cracks, bending or excessive wear are likely to occur in the bending section, and it is necessary to avoid physical impact on the bending section by other external structures. The protruding ear plate 760 can effectively reduce the possibility of the bending section directly contacting external objects through physical shielding, avoiding direct impact and damage to these vulnerable components by external factors. This not only improves the service life and stability of the conductive connector 700, but also reduces the maintenance cost.

[0111] In some embodiments, as shown in the figure, the ear plate 760 on one of the wing plates 720 is bent towards the other wing plate 720 to form a second substrate 770 parallel to the first substrate 710. By bending the ear plate 760 formed on the wing plate 720 to form the second substrate 770, the conductive connector 700 can not only be connected to the second circuit board 200 through the first substrate 710, but also be connected to the circuit board of the external circuit through the second substrate 770. This design provides multiple connection methods, and users can choose the appropriate connection method according to different application requirements, making the conductive connector 700 more widely applicable.

[0112] The second substrate 770 is similar to the first substrate 710 and is a non-elastic structure. Compared with the dynamic extrusion connection method provided by the combination of the elastic sheet 730 and the first substrate 710, the combination of the second substrate 770 and the first substrate 710 provides a static connection solution. By connecting the conductive connector 700 to the external circuit board through the second substrate 770, electrical connection can be completed without relying on elastic deformation, which is suitable for occasions with high requirements for connection stability. The first substrate 710 and the second substrate 770 can be respectively used for the static connection between two circuit boards, making the product more flexible and allowing different connection solutions to be selected according to requirements. The design of the second substrate 770 increases the connection stability. Especially in the case where large mechanical stress needs to be borne, as a non-elastic structure, the second substrate 770 can effectively prevent poor electrical contact caused by deformation at the connection point, thereby improving the service life and electrical performance of the entire conductive connector 700.

[0113] The cooperation between the elastic sheet 730 and the first substrate 710 is mainly used to realize the pressing contact connection between the second circuit board 200 and the external circuit structure. This pressing contact connection can provide more stable electrical contact during the installation process, ensuring the reliability of the connection. The static connection function of the second substrate 770 provides another option, making the connection method more flexible. By providing the dual connection methods of the elastic sheet 730 and the second substrate 770, the best connection scheme can be selected according to specific needs during installation. For example, if a strong physical connection strength needs to be maintained during installation, the static connection method of the second substrate 770 will be a preferred solution. For application scenarios that require dynamic connection or high flexibility, the cooperation between the elastic sheet 730 and the first substrate 710 can be selected. Users can flexibly choose the appropriate connection method according to specific needs, which can not only ensure the reliability of the electrical connection but also improve the adaptability of the product to meet the requirements in different environments.

[0114] In some embodiments, as shown in the figure, a reinforcing rib 780 is provided at the connection between the wing plate 720 and the first limiting portion 740. The cooperation between the first limiting portion 740 and the second limiting portion 750 requires certain mechanical support. Especially in the initial state, the elastic sheet 730 is limited in a preset deformed state, and the first limiting portion 740 and the second limiting portion 750 are always in contact with each other, and the first limiting portion 740 will bear a certain amount of pressure or stress. The provision of the reinforcing rib 780 can effectively enhance the structural strength of the first limiting portion 740, thereby preventing it from deforming, being damaged or suffering from fatigue failure during the stress-bearing process, and maintaining stability for a longer time.

[0115] In some embodiments, as shown in the figure, a stress relief hole 790 is formed at the connection between the wing plate 720 and the first substrate 710. In traditional structural designs, the connection or bending points often become stress concentration areas, and long-term stress may lead to material fatigue, cracking or failure. By providing the stress relief hole 790 at the connection between the wing plate 720 and the first substrate 710, the presence of the stress relief hole 790 can make the stress evenly distributed along the hole wall, avoiding the local stress concentration phenomenon in traditional designs, effectively dispersing the stress, reducing the stress concentration at the connection, and thus reducing the risk of component damage during use. The design of the stress relief hole 790 can also make the component obtain a lighter weight and lower material cost.

[0116] In the specific usage process, the bent section 733 of the conductive connector 700 in the foregoing embodiment abuts against the second limiting piece 125. The first limiting piece 124 is fixedly connected to the bracket 110. The second limiting piece 125 is in physical contact with the elastic piece 730 by contacting the bent section 733 of the conductive connector 700, so that the elastic piece 730 is extruded, and the elastic piece 730 is deformed, realizing the extrusion connection between the second limiting piece 125 and the conductive connector 700. The first substrate 710 of the conductive connector 700 is connected to the second circuit board 200 through its back surface, ensuring the stable electrical connection between the circuit system and the switch assembly. The bent section 733 of the elastic piece 730 of the conductive connector 700 abuts against the second limiting piece 125 of the limiting member 120 and is pressed by the second limiting piece 125. The elastic piece 730 will be further deformed relative to its initial state when not installed, and the first limiting portion 740 and the second limiting portion 750 are separated, realizing the stable connection between the elastic piece 730 and the second limiting piece 125. The conductive connector 700 realizes the connection between the limiting member 120 and the second circuit board 200 of the circuit system in the electronic device, and can transmit the touch electrical signal under the touch function to the circuit system of the electronic device.

[0117] The design of the conductive connector 700 enables the elastic piece 730 to obtain a stable electrical connection only by slightly deforming and adjusting it during the installation process. The deformation adjustment amount during the installation process is smaller, reducing the operation steps that require a large deformation amount in the traditional technology, making the installation process simpler and more efficient.

[0118] In some embodiments, such as Figure 2 , Figures 6 - 8 , Figures 10 - 13As shown, a positioning projection 119 is formed on one side of the bracket 110 facing the first limiting piece 124, and a second through hole 126 that is matingly connected to the positioning projection 119 is formed on the first limiting piece 124. The cooperation between the positioning projection 119 and the second through hole 126 is used to ensure quick positioning of the limiting member 120 when assembled to the bracket 110, avoiding deviation or misalignment. The specific installation steps can be as follows: First, put the second through hole 126 onto the positioning projection 119 to ensure that the surface of the limiting member 120 fits against the bracket 110. Through this cooperation, the second through hole 126 of the limiting member 120 has been accurately positioned at the predetermined position of the bracket 110 during the initial assembly; then, after ensuring that the second through hole 126 is put on the positioning projection 119, gently rotate the first limiting piece 124 around the positioning projection 119 until the first through hole 122 is aligned with the second installation groove 113. At this time, the limiting member 120 is in the correct angle and position, preparing for the next fixing step; finally, when the first through hole 122 is aligned with the second installation groove 113, insert the fixing post 152 into the first through hole 122 and the second installation groove 113, and screw the fixing post 152 into the second installation groove 113 by screwing to complete the firm fixing of the limiting member 120.

[0119] Through the cooperation between the positioning projection 119 and the second through hole 126, it is possible to assist in accurately fixing the limiting member 120 at the predetermined position during the installation process, avoiding deviation during assembly and improving the assembly accuracy. This design can accurately dock the limiting member 120 to the correct position through a simple rotation operation, without the need for complex adjustment or additional tools, reducing the position error of adjustment and inspection during the assembly process, thereby improving the overall assembly efficiency. The cooperation between the positioning projection 119 and the second through hole 126 not only ensures accurate initial positioning, but also enables the limiting member 120 to achieve a double-point fixing effect through the positioning projection 119 and the fixing post 152 after installation, enhancing the stability of the connection.

[0120] The embodiment of the present application also correspondingly protects a wearable electronic device, which includes the switch assembly provided in the foregoing embodiment of the present application.

[0121] Specifically, as Figures 1 - 6 shown, the main structure of the wearable electronic device further includes a middle frame 300, a bottom case 400, and a first circuit board 500.

[0122] In a wearable electronic device, a button hole 310 penetrating the inner and outer sides of the middle frame 300 is formed on the middle frame 300; a bottom case 400 is fixed to one side of the middle frame 300 in the thickness direction, and a fixing seat 410 located inside the middle frame 300 and facing the button hole 310 is provided on the bottom case 400; a first circuit board 500 is disposed between the fixing seat 410 and the switch element 160; the switch element 160 is connected to the first circuit board 500; a switch assembly is installed in the button hole 310 and is configured to trigger the switch element 160 by pressing the switch assembly.

[0123] The middle frame 300 serves as the external frame structure of the electronic device, and the bottom case 400 is connected to the middle frame 300 and closes the back of the electronic device. The middle frame 300 and the bottom case 400 together carry and support various internal components of the wearable electronic device, protecting the internal circuit and components. A button hole 310 penetrating the inner and outer sides is formed on the middle frame 300 for accommodating and fixing the pressing assembly. The shape and size of the button hole 310 are determined according to the design requirements of the pressing assembly to ensure that the pressing assembly can be smoothly installed and fixed and adapt to the pressing action.

[0124] The first circuit board 500 is disposed on the fixing seat 410, and the switch element 160 is connected to the first circuit board 500. The switch element 160 is a key component in the electronic device for receiving physical pressing and transmitting an electrical signal to the first circuit board 500 after being pressed and triggered. Since the fixing seat 410 is integrated on the bottom case 400 and is directly connected to the first circuit board 500, the fixing of the switch element 160 becomes more convenient and firm. The switch assembly is installed in the button hole 310. When the user presses the pressing assembly, through the movement of some mechanisms, the switch element 160 is finally triggered by pressing. In this design, the first circuit board 500 is disposed between the fixing seat 410 and the switch element 160. The side of the switch element 160 facing the pressing assembly directly being physically pressed is defined as the front of the switch element 160. An electrical connection can be formed between the first circuit board and the back of the switch element 160 through the back of the switch element 160 as the connection contact. Since the first circuit board 500 is sandwiched between the fixing seat 410 and the back of the switch element 160, after the front of the switch element 160 is physically pressed by the pressing assembly, the first circuit board 500 is squeezed and will form a more stable contact connection with the switch element 160. Compared with leading out connection contacts from the side of the switch element to connect with the circuit board, there is no need to set relevant elastic conductive structures for transitional connection, simplifying the product structure and reducing the processing and assembly costs.

[0125] In addition, in the related art, there is a related solution in which both the fixed seat and the switch member are integrated on the switch assembly, and the first circuit board is clamped between the fixed seat and the back surface of the switch member. Although it can also achieve the effect of stably connecting the first circuit board and the switch member under frequent pressure, it makes the structure of the switch assembly too complex, and the connection position and connection method of the switch member and the first circuit board are limited by the specific structure of the pressing assembly, resulting in an adverse impact. In the present application, by arranging the fixed seat on the bottom case, the internal space of the electronic device and the laying requirements of the first circuit board in the electronic device can be fully utilized, the position of the fixed seat can be reasonably set, and the structure of the switch assembly will not be overly complicated.

[0126] In some embodiments, the bottom case 400 and the fixed seat 410 are integrally formed. The fixed seat 410 is located inside the middle frame 300 and is directly opposite to the key hole 310. The fixed seat 410 is manufactured by an integral forming method, which ensures the structural stability, reduces the number of components, and avoids the need for an additional switch fixing bracket in the traditional design. Therefore, this design simplifies the production process and reduces the processing and assembly costs.

[0127] In summary, in the above embodiments of the present application, by integrally forming the fixed seat 410 on the bottom case 400, there is no need to additionally design an independent fixing bracket to fix the switch member 160. On the one hand, it effectively simplifies the overall structure of the electronic device, reduces the number of components, and the simplified structural design further reduces the processes and assembly steps required in the production process, reducing the production cost and assembly difficulty. On the other hand, the integrally formed fixed seat 410 provides stable support, avoiding the loosening or wear problems that may be caused by unstable assembly of the switch fixing bracket in the traditional design. It is particularly suitable for modern consumer electronic devices, especially products such as smart watches that have high requirements for miniaturization and thinness.

[0128] Preferably, the switch element 160 is bonded to the first circuit board 500 by SMT process. SMT process is used to directly bond electronic components to the surface of the circuit board, rather than connecting them by the traditional pin insertion hole method. The application of SMT process can greatly improve production efficiency, reduce space occupation, and more accurately control the connection quality during the manufacturing process. Bonding the switch element 160 to the first circuit board 500 by SMT process can achieve high-precision bonding, reduce human errors, and greatly improve the bonding efficiency due to the use of automated equipment. The switch element 160 in the traditional process may need to be inserted into the circuit board or other connection methods by pins, which will take up more board space. Using SMT process, the switch element 160 is directly bonded to the surface of the circuit board, which not only improves space utilization, but also makes the overall design of the circuit board more compact, adapting to the needs of increasingly miniaturized and thin electronic devices. The automation and precision of SMT process are high, and the bonding process is more stable and reliable. In the process, high-temperature welding (such as reflow soldering) can ensure that the connection between the switch element 160 and the first circuit board 500 is stable and durable. This firm connection can effectively reduce the problem of the switch 160 falling off or having poor contact during use, thereby improving the long-term stability of the product.

[0129] The steps of attaching the switch component 160 to the first circuit board 500 through the SMT process can refer to the following records: First, the switch component 160 is pre-processed to adapt to the SMT process, and the back contact surface of the switch component 160 can be coated with a layer of solderable material to ensure the welding quality; then the switch component 160 is accurately mounted on the specified position of the first circuit board 500 using the SMT equipment. The SMT equipment uses surface mounting technology to accurately position and weld components, and the switch component 160 will be directly attached to the surface of the first circuit board 500; then the back pad of the switch component 160 is connected to the pad on the first circuit board 500 through the reflow soldering process. During the reflow soldering process, the soldering material is heated and melted to form a reliable electrical connection; finally, after the mounting and welding are completed, visual inspection and electrical testing are performed to ensure that the connection between the switch component 160 and the first circuit board 500 is good and there are no welding defects or poor contact.

[0130] In some embodiments, the first circuit board 500 is a flexible circuit board. Flexible circuit boards have good flexibility and bendability, and are suitable for electronic devices that require higher integration and compact design. However, due to the thinness and flexibility of flexible circuit boards, they may bend and deform to a certain extent when subjected to external stress and physical pressure, thereby affecting the stability and reliability of the circuit. In order to overcome this problem, the stability and durability of the product are further optimized, such as Figure 2 and 6As shown, this embodiment provides a reinforcement design, that is, a reinforcing plate 600 is provided between the first circuit board 500 and the fixed seat 410.

[0131] The reinforcing plate 600 is usually made of a material with relatively high rigidity (such as metal or hard plastic), and has sufficient rigidity and strength to prevent the flexible circuit board from affecting its electrical performance or being damaged due to pressure or bending deformation during long-term use. The design of the reinforcing plate 600 can be customized according to the specific shape, size of the first circuit board 500 and the requirements of the installation space. The reinforcing plate 600 is installed in a closely fitting manner with the first circuit board 500, so that a support structure is formed between the reinforcing plate 600 and the flexible circuit board, ensuring that the flexible circuit board remains flat under external forces and reducing the phenomenon of poor contact or breakage caused by bending or pressure. The reinforcing plate 600 effectively enhances the rigidity of the flexible circuit board, prevents the circuit board from being damaged or having poor connection due to bending or external force during use, and improves the reliability of the first circuit board 500.

[0132] In some embodiments, as Figure 2 and 6 shown, the fixed seat 410 includes a first vertical plate 411 and a second vertical plate 412 connected vertically. The first vertical plate 411 is disposed opposite to the key hole 310. The surface of the reinforcing plate 600 away from the switch assembly is adhesively connected to the first vertical plate 411, and one side of the reinforcing plate 600 and the first circuit board 500 abuts against the second vertical plate 412. Specifically, the first vertical plate 411 is disposed opposite to the key hole 310 for providing a stable support surface for the switch assembly. The position and shape of the key hole 310 are precisely designed to ensure that the pressing assembly can accurately dock with the switch 160 and trigger corresponding signals after assembly. The adhesive connection between the reinforcing plate 600 and the first vertical plate 411 is the key to achieving structural stability. One side of the reinforcing plate 600 is adhesively connected to the first vertical plate 411, and the other side of the reinforcing plate 600 is closely fitted with the first circuit board 500. In this way, the reinforcing plate 600 is supported by the first vertical plate 411, avoiding possible deformation or stress concentration of the flexible circuit board during use. This combination not only increases the mechanical strength of the first circuit board 500, but also prevents poor contact caused by long-term pressing or vibration.

[0133] During the operation of the switch assembly, when the user presses the switch assembly, the pressing force generated acts directly on the switch 160 through the switch assembly, and then is transmitted to the first vertical plate 411 through the first circuit board 500 and the reinforcement plate 600. The first vertical plate 411 becomes the final pressure-bearing structure and bears all the pressure from the switch assembly. Therefore, the first vertical plate 411 must have sufficient strength and rigidity to ensure that it will not deform or be damaged during the pressing process. The second vertical plate 412 is vertically connected to the first vertical plate 411. This structural design of vertical connection greatly enhances the mechanical stability of the first vertical plate 411 when bearing the pressing force. Specifically, the bottom case 400, the first vertical plate 411, and the second vertical plate 412 form a stable three-dimensional structure in space through a pairwise orthogonal structural form. This structure can effectively withstand the impact force from the switch assembly, thereby improving the overall load-bearing capacity.

[0134] Another function of the second vertical plate 412 is to provide an additional positioning surface for the reinforcement plate 600 and the first circuit board 500, so that the thickness sides of the reinforcement plate 600 and the first circuit board 500 can stably abut against the second vertical plate 412. The position of the reinforcement plate 600 and the first circuit board 500 in the direction perpendicular to the second vertical plate 412 is positioned through the second vertical plate 412. Through the vertical connection of the first vertical plate 411 and the second vertical plate 412, the entire fixing base 410 can position the reinforcement plate 600 and the first circuit board 500 in the directions perpendicular to the first vertical plate 411 and perpendicular to the second vertical plate 412, improving the assembly efficiency of the components, making the assembly more accurate, greatly simplifying the traditional complex assembly process, and improving the production efficiency.

[0135] In some embodiments, the bracket 110 is embedded in the keyhole 310 and fixedly connected to the middle frame 300. The fixation of the bracket 110 and the middle frame 300 improves the connection stability and sealing effect. The middle frame 300, as the main support structure of the electronic device, its fixed connection with the bracket 110 ensures the stability of the pressing assembly. During the operation of the key 130, the bracket 110, as the load-bearing structure, can effectively disperse some of the pressure borne by the key to the middle frame 300. Since the bracket 110 is fixedly connected to the middle frame 300, the sealing effect at the connection is enhanced, preventing external dust, moisture, etc. from entering the interior of the wearable electronic device through the gap between the bracket 110 and the middle frame 300, which helps to improve the protection ability of the wearable electronic device, especially in terms of water tightness and dust tightness, ensuring that the device can work stably under different environmental conditions, and improving the durability and reliability of the entire electronic device.

[0136] In some embodiments, the bracket 110 is adhesively fixed within the button hole 310 of the middle frame 300 through a dispensing process. This dispensing process forms a firm connection between the bracket 110 and the middle frame 300 by applying glue at the interface where the bracket 110 contacts the middle frame 300. The dispensing process is characterized by simple operation and high efficiency, and can ensure the sealing and stability between the bracket 110 and the middle frame 300. In addition, the choice of glue can be adjusted according to the specific requirements of the electronic device to ensure that it is not prone to aging or falling off during long-term use.

[0137] The dispensing process does not require complex mechanical connections or additional fasteners, can achieve a stable connection in a short time, and reduces the labor cost and assembly cycle in the production process. Through dispensing fixation, a thin and uniform sealing glue layer can be formed on the contact surface between the bracket 110 and the button hole 310, further enhancing the waterproof and dustproof capabilities of the electronic device. Especially when used in harsh environments, it can prevent dust and moisture from invading the interior of the device. The dispensing process can provide sufficient adhesive force to ensure the firm fixation between the bracket 110 and the middle frame 300, avoid loosening or displacement during use, and improve the stability and reliability of the device. The glue will be evenly distributed on the contact surface between the bracket 110 and the middle frame 300 during dispensing, which helps to disperse the pressure generated during the operation of the button 130, reduce local stress concentration, and thus extend the service life of the button 130.

[0138] In some embodiments, such as Figure 3 , Figure 7 , Figures 11 - 12 shown, the button hole 310 includes a first hole section 311 near the inner side and a second hole section 312 near the outer side. The cross-section of the first hole section 311 is smaller than that of the second hole section 312, and a first abutting surface 313 facing outward is formed between the first hole section 311 and the second hole section 312; the bracket 110 includes a first bracket section 116 adapted to the first hole section 311 and a second bracket section 117 adapted to the second hole section 312. A second abutting surface 118 facing the first abutting surface 313 is formed between the first bracket section 116 and the second bracket section 117. In the state where the bracket 110 is fitted and embedded in the button hole 310, the first abutting surface 313 and the second abutting surface 118 are in abutting cooperation.

[0139] When the first bracket segment 116 and the second bracket segment 117 of the bracket 110 are precisely adapted to the first hole segment 311 and the second hole segment 312 of the keyhole 310 respectively, the first abutting surface 313 and the second abutting surface 118 cooperate with each other, thus ensuring a tight connection between the bracket 110 and the middle frame 300, effectively avoiding problems such as loosening or misalignment during the assembly process, and improving the connection stability. The mating design formed by the first abutting surface 313 and the second abutting surface 118 can automatically complete the positioning when the bracket 110 is installed into the keyhole 310, without the need for additional fixing parts or complex assembly operations. In this way, the installation of the bracket 110 is more convenient, avoiding errors or position offsets that may occur in the traditional installation method, and improving the overall assembly efficiency compared with the traditional manual positioning and alignment process. The bracket 110 effectively disperses the impact force during the pressing of the key 130 through the surface contact and cooperation of the first abutting surface 313 and the second abutting surface 118, reducing the loosening or deformation of the bracket 110 caused by force concentration, and enhancing the durability and stability of the overall structure.

[0140] During the actual assembly process, first insert one end of the first bracket segment 116 of the bracket 110 from the outside of the keyhole 310. When the bracket 110 is completely inserted into the keyhole 310, the first abutting surface 313 and the second abutting surface 118 abut against each other, and at this time, the precise positioning between the bracket 110 and the middle frame 300 is completed. During this process, the abutting surfaces help the bracket 110 to be stably positioned in the middle frame 300 through contact and cooperation, avoiding position deviation or loosening that may occur during the assembly process, and ensuring a firm connection between the bracket 110 and the keyhole 310.

[0141] Based on the above embodiments, one end of the second bracket segment 117 is connected to the outer contour of one end of the first bracket segment 116 and is recessed to form a dispensing segment 1171. In a state where the bracket 110 is fitted and embedded in the button hole 310, the dispensing segment 1171, the first abutting surface 313, and the inner wall of the second hole segment 312 enclose a dispensing groove 170. By designing the dispensing segment 1171 to cooperate with the bracket 110 to form the dispensing groove 170, the dispensing material can be effectively accommodated, thereby ensuring that the dispensing process can distribute the glue more accurately and evenly in the area where the bracket 110 contacts the button hole 310. The setting of the dispensing segment 1171 and the dispensing groove 170 effectively enhances the bonding firmness between the bracket 110 and the middle frame 300, and avoids loosening or separation caused by uneven dispensing or weak bonding. In traditional assembly, the dispensing process requires additional tools or complex operations. By designing the dispensing segment 1171 on the bracket 110 and forming the dispensing groove 170, the dispensing process can be made more automated and simple. The operator only needs to pre-place the dispensing material in the dispensing segment 1171, without precise alignment and manual application, thereby improving the assembly efficiency. The glue bonding provided by the dispensing segment 1171 and the dispensing groove 170 not only enhances the connection strength between the bracket 110 and the middle frame 300, but also can effectively absorb the impact force generated during pressing, reduce local damage caused by force concentration, and improve the anti-impact ability of the product during use.

[0142] The specific assembly process can be exemplified as follows: First, apply an appropriate amount of dispensing material to the area of the dispensing segment 1171 of the bracket 110; then insert the dispensed bracket 110 into the button hole 310. At this time, a dispensing groove 170 is formed between the dispensing segment 1171 of the bracket 110 and the inner wall of the second hole segment 312 and the first abutting surface 313 in the button hole 310, and the glue in the dispensing groove 170 is pressed tightly during this process to form a firm bonding force; after dispensing is completed and the bracket 110 is installed, wait for the glue to cure. During the curing process, a long-term bonding force is formed between the contact surfaces of the glue with the bracket 110 and the button hole 310, effectively enhancing the bonding strength between the bracket 110 and the middle frame 300, thereby improving the anti-impact ability and service life of the entire device, especially suitable for use in an environment with frequent pressing and collision. Through the design of the dispensing segment 1171 and the dispensing groove 170, the need for other connection methods (such as screw fixation, etc.) is reduced, the production cost of the product is lowered, and the assembly process is simplified.

[0143] In some embodiments, the bracket 110 is fixed within the button hole 310 of the middle frame 300 through an injection molding process. The injection molding process involves injecting a plastic material into a mold and forming it within the mold, ultimately achieving a firm bond between the bracket 110 and the middle frame 300. The injection molding process can efficiently and precisely manufacture components with complex shapes and precise dimensions, featuring high production efficiency and consistency. The injection molding process can precisely control the dimensions and shape of the bracket 110, ensuring a good fit between the bracket 110 and the button hole 310 of the middle frame 300 and avoiding the inability to use the button 130 properly due to dimensional errors. After being formed by the injection molding process, the connection between the bracket 110 and the middle frame 300 is more stable and firm, capable of effectively withstanding external impacts and pressures and avoiding loosening or detachment of the connection under frequent pressing operations. Different types of plastic materials can be selected for the injection molding process to meet the requirements of different electronic devices for strength, wear resistance, and waterproof performance. For example, using high-strength plastics can enhance the compressive capacity of the bracket 110, while using flexible materials can improve the anti-impact and shock-absorbing capabilities. The injection molding process is suitable for large-scale production and can produce a large number of bracket 110 and middle frame 300 components of the same specifications in a short time, thereby improving production efficiency and reducing the unit production cost.
