Abstract

This invention relates to a switch assembly and a wearable electronic device. The switch assembly includes a bracket, a button, a limiting member, a reset member, and a switching element. The button includes a keycap and a key shaft, the key shaft passing through a first shaft hole and movable axially along the first shaft hole. The end of the key shaft away from the keycap forms a first shaft segment. The keycap and the first shaft segment are located on opposite sides of the bracket, and the first shaft segment has a first abutment surface facing the bracket. The reset member is configured such that the first abutment surface always tends to move axially towards the limiting member along the first shaft hole. The reset force of the reset member causes the first abutment surface to engage with the limiting member, achieving axial limiting of the button to prevent it from disengaging. This eliminates the need for additional limiting components such as clips or screws, simplifying the product structure, reducing assembly complexity, and lowering the risk of parts falling off.

Description

Technical Field

[0001] This invention relates to the field of electronic device technology, and more specifically to a switching component and a wearable electronic device. Prior Technology

[0002] In modern electronic devices, switching components serve as a crucial structure for user interaction and are widely used in various consumer electronics products, such as mobile phones, computers, televisions, home appliances, and wearable electronic devices. With technological advancements, the design of switching components is increasingly trending towards miniaturization, thinning, and high reliability.

[0003] The main structure of the switch assembly includes a button, a bracket, a spring element, and a switching element. The button includes a keycap and a key lever. Pressing the keycap moves the key lever relative to the bracket, thereby triggering the switching element. When the keycap is released, the spring element drives the button to reset. To ensure the button remains stable in the reset position and prevent it from detaching from the bracket, a corresponding limiting structure is required.

[0004] In some related technologies, corresponding flanges or snap-fit ​​structures are set on the edge of the keycap to create a locking effect with the bracket to achieve the limiting effect. This method requires modification of both the keycap and the bracket structure, resulting in a complex product structure and increased processing and assembly costs. In other related technologies, a retaining spring is fitted onto the key stem, which creates a limiting effect with the bracket. However, in this method, the retaining spring and the key stem have a detachable sleeve connection, which can cause slight wobbling in the limiting state, making the connection unstable, and there is a risk of the retaining spring falling off. Summary of the Invention

[0005] This invention provides a switching assembly and a wearable electronic device to solve the technical problems in related technologies where the limiting structure of the switch in the switch assembly is complex or there is a risk of parts falling off.

[0006] A first aspect of the present invention provides a switching assembly comprising: A bracket, on which a through first shaft hole is formed; A key includes a keycap and a key shaft, the key shaft passing through the first shaft hole and movable axially along the first shaft hole, the end of the key shaft away from the keycap forming a first shaft segment, the keycap and the first shaft segment being located on opposite sides of the bracket, the first shaft segment having a first abutting surface facing the bracket; A limiting element is disposed between the first shaft segment and the bracket; A reset element is configured such that the first abutment surface always tends to move toward the limiting element along the axial direction of the first shaft hole; A switch is disposed on the side of the first axis segment away from the keycap. When the key is pressed, the first axis segment moves toward the switch and triggers the switch.

[0007] A second aspect of the present invention provides a wearable electronic device comprising the switching assembly provided in the first aspect of the present invention.

[0008] Compared with the prior art, the technical means provided in this embodiment of the invention has the following advantages: Due to the presence of the reset component, when the key is in its natural state without being pressed by external force, the first contact surface abuts against the limiting component; when the user presses the keycap, causing the key to move towards the switch component against the reset force of the reset component, the third contact surface gradually approaches and presses against the switch component to trigger it. After the user releases the key in the pressed state, the reset component drives the key shaft to move axially along the first shaft hole, causing the first contact surface to contact the limiting component, the key resets, and the limiting component plays another limiting role at the extreme position, preventing the key shaft from detaching from the bracket. On the one hand, the embodiments of the present invention utilize the resetting force of the reset member to make it abut against the first contact surface and the limiting member, thereby achieving axial limiting of the button to prevent the button from falling out. There is no need to set additional limiting components such as buckles or screws, which simplifies the product structure and reduces assembly complexity. On the other hand, the limiting member in the embodiments of the present invention is a fixed structure, and the first shaft segment is the structure of the key shaft itself. Compared with the limiting by sleeved spring sheet on the key shaft, the contact limiting between the first shaft segment and the limiting member can improve the stability in the limiting state and reduce the risk of parts falling off.

Implementation

[0010] To make the objectives, technical means, and advantages of the embodiments of the present invention clearer, the technical means of the embodiments of the present invention will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0011] The main structure of the switch assembly provided in this embodiment of the invention includes a bracket 110, a button 130, a limiting member 120, a reset member 140, and a switch member 160. The switch assembly is an important component of various electronic devices. As a trigger interaction structure for user interaction with electronic devices, it can be widely used in various consumer electronic devices, including but not limited to mobile phones, tablets, scanning pens, digital cameras, and smartwatches. This specification uses the application of this switch assembly in a wearable electronic device such as a smartwatch, as shown in Figures 1 and 4-5, as an example for illustrative purposes.

[0012] As shown in Figures 1 to 13, the bracket 110 of the switch assembly has a through first shaft hole 111, which extends 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 passes through the first shaft hole 111 and can move axially along the first shaft hole 111. The keycap 132 is located on the first side of the bracket 110. The end of the key shaft 131 away from the keycap 132 forms a first shaft segment 1311. The keycap 132 and the first shaft segment 1311 are respectively located on the two sides of the bracket 110. On the side, the first shaft segment 1311 has a first abutting surface 1314 facing the bracket 110; the limiting member 120 is disposed between the first shaft segment 1311 and the bracket 110; the reset member 140 is configured such that the first abutting surface 1314 always has a tendency to move towards the limiting member 120 along the axial direction of the first shaft hole 111; the switch member 160 is disposed on the side of the first shaft segment 1311 away from the keycap 132, and when the button 130 is pressed, the first shaft segment 1311 moves towards the switch member 160 and triggers the switch member 160.

[0013] In the above embodiment, the bracket 110 is used to fix it to a specific electronic device. As the main load-bearing structure, it also supports 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 160 as a conventional physical button. The switch 160 is used to connect directly or indirectly to the circuit system of the electronic device and transmit electrical signals to the circuit system.

[0014] The keycap 132 of the key 130 is designed to be suitable for finger touch and pressing. Its surface can be provided with anti-slip texture and appropriate surface area as needed to be suitable for finger touch and pressing. The keycap 132 is located on the first side of the bracket 110. The keycap 132 itself will protrude radially from the key shaft 131 relative to the key shaft 131. During the movement of the key shaft 131 along the first shaft hole 111 toward the switch 160, the keycap 132 will be blocked and unable to move after it comes into contact with the bracket 110. The keycap 132 can play a limiting role at the extreme position.

[0015] The first shaft segment 1311 is located at the end of the key shaft 131 away from the keycap 132. The surface of the first shaft segment 1311 facing the limiting member 120 is machined with a first abutting surface 1314, and the surface facing away from the limiting member 120 is machined with a third abutting surface 1317. Due to the presence of the reset member 140, when the key 130 is not pressed by external force and is in its natural state, the first abutting surface 1314 abuts against the limiting member 120; when the user presses the keycap 132, causing the key 130 to move 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 pressed button 130, 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, the button 130 is reset, and the limiting member 120 plays another limiting role at the extreme position, so that the key shaft 131 cannot be detached from the bracket 110.

[0016] On the one hand, in the above embodiment, the reset force of the reset member 140 is used to make the first contact surface 1314 abut against the limiting member 120, thereby realizing the axial limiting of the button 130 to prevent the button 130 from falling out. There is no need to set additional 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 segment 1311 is the structure of the key shaft 131 itself. Compared with the limiting by sleeved spring sheet on the key shaft 131, the contact limiting between the first shaft segment 1311 and the limiting member 120 can improve the stability in the limiting state and reduce the risk of parts falling off.

[0017] Preferably, the limiting member 120 is a plate structure, with a plane parallel to the first abutment surface 1314 formed on the side facing the first shaft segment 1311, so that the first shaft segment 1311 and the limiting member 120 are in surface contact when they abut, which further improves the stability in the limiting state.

[0018] In some embodiments, as shown in Figures 2, 8-9, and 12-13, a groove 1316 is provided circumferentially on the key shaft 131 of the switch assembly. A sealing ring 133 is fitted onto the groove 1316, and the sealing ring 133 is sealed to the inner wall of the first shaft hole 111. In this embodiment, the sealing ring 133 is sealed to the inner wall of the first shaft hole 111 to prevent external liquids or dust from entering the assembly, protecting the internal electronic components from contamination and damage, and improving the protection level of the assembly. This makes it suitable for applications requiring waterproofing and dustproofing. The presence of the sealing ring 133 enhances the connection stability between the key shaft 131 and the first shaft hole 111, reduces loosening or displacement caused by friction or vibration, and ensures the long-term reliability of the assembly. By providing a groove 1316 on the key shaft 131 and fitting a sealing ring 133, the design of the sealing structure is simplified, and the complexity of production and assembly is reduced.

[0019] In some embodiments, as shown in Figures 2-3, 8, and 11-12, the support 110 of the switch assembly has a receiving groove 114 on the side facing the keycap 132, which matches the shape of 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 axial direction during pressing, and to prevent deviation or tilting. In the design of the receiving groove 114, the groove wall fits tightly with the outer edge of the keycap 132, so that the keycap 132 will not wobble or rub unnecessarily when pressed, thereby ensuring the smoothness and comfort of the pressing action. In addition, the bottom of the receiving groove 114 is designed with a certain depth to provide a limiting effect on the axial movement of the keycap 132 during the pressing state.

[0020] Specifically, during the pressing process, the keycap 132 can move freely along the wall of the receiving groove 114. However, the axial movement of the keycap 132 is limited by the bottom of the receiving groove 114 to prevent it from exceeding the set range of motion. This limiting effect of the bottom of the groove effectively prevents excessive movement of the keycap 132 during pressing, thereby avoiding excessive pressure on the switch element 160 by the key shaft 131 and ensuring the service life and stability of the switch element 160. In other words, the receiving groove 114 not only enhances the stability of the fit between the keycap 132 and the bracket 110, but also limits the movement of the keycap 132, preventing excessive pressing or uncontrolled movement of the keycap 132 from adversely affecting the internal switch element 160, greatly improving the reliability and user experience of the keycap 130.

[0021] In some embodiments, as shown in Figures 2-3, 8, and 11-13, the reset element 140 of the switch assembly is a spring disposed between the keycap 132 and the bracket 110. The bracket 110 has a third mounting groove 115 on the side facing the keycap 132 for mounting the spring. The working principle of the spring is to store mechanical energy. When the keycap 130 is pressed by an external force, it compresses and stores elastic potential energy. When the external force is released, the spring releases the stored energy, pushing the keycap 130 back to its initial position, thereby completing the reset action. This allows the keycap 130 to automatically reset to its initial state after being pressed. The design of the third mounting groove 115 allows the spring, which serves as the reset element 140, to maintain the correct position when the keycap 130 is pressed, avoiding positional displacement or unnecessary deformation of the spring 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 adapt to the outer surface of the spring, thereby fixing the position of the spring and preventing it from shifting or excessively wobbling during operation, and limiting the direction of the spring force to be parallel to the axial direction of the key shaft 131. The depth of the third mounting groove 115 ensures that the spring can freely expand and compress during the keycap 132 pressing and reset process to provide sufficient restoring force. The opening of the third mounting groove 115 not only provides a mounting position for the spring, but also allows for precise control of the spring's position and force state, improves the stability of the reset function, avoids possible damage or failure of the spring, and ensures that it maintains good performance during repeated pressing.

[0022] In some embodiments, as shown in Figures 3, 9, and 12, the keycap 132 of the switch assembly has a limiting groove 1321 facing the bracket 110, which is directly opposite the third mounting groove 115. One end of the spring is confined 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 radially displacing during operation, thereby avoiding uneven force on the spring and ensuring a smooth and consistent pressing and resetting process of the keycap 132, thus improving the service life and overall stability of the button 130. In addition, the cooperation between the limiting groove 1321 and the third mounting groove 115 allows the two ends of the spring to be limited and stabilized through the corresponding third mounting groove 115 and limiting groove 1321, thereby further avoiding uneven force on the keycap 132 or unsmooth operation of the button 130 due to spring instability, and ensuring that the spring does not undergo radial displacement or tilting during operation.

[0023] In some embodiments, as shown in Figures 2 or 12, the spring, third mounting groove 115, and limiting groove 1321 of the switch assembly are provided in two sets and symmetrically distributed on both sides of the key shaft 131. Each side of the key shaft 131 has a set of third mounting groove 115 and limiting groove 1321, with the two ends of the spring engaging with these grooves respectively. This design effectively avoids eccentric forces or asymmetrical pressures that may result from a unilateral design, thereby enhancing the overall stability of the switch assembly. The symmetrically distributed springs on both sides maintain balance during the pressing and resetting of the button 130, preventing incomplete resetting or unresponsive pressing of the button 130 due to uneven spring force. Simultaneously, this design also reduces component wear caused by uneven force.

[0024] In some embodiments, both the limiting member 120 and the button 130 are conductors, and the bracket 110 is an insulator. The limiting member 120 is configured to be electrically connected to the second circuit board 200. In this embodiment, the cooperation between the button 130 and the limiting member 120 enables the conduction of the touch button 130 signal. Specifically, in the above embodiment, the first contact surface 1314 of the button 130 and the limiting member 120 participate in forming a conduction path. The button 130 is used to conduct electrical signals after being touched, and the limiting member 120 is used to connect directly or indirectly to the circuit system of the electronic device, specifically to the second circuit board 200, thereby transmitting the touch electrical signal under the touch function to the circuit system. When the touch-activated function is needed, the user touches the outer surface of the button 130 with their finger. The button 130 does not move, and the first contact surface 1314 and the limiting member 120 remain in contact. At this time, the keycap 132 of the button 130, the first contact surface 1314, the limiting member 120, and the second circuit board 200 will participate in forming the first conductive path, transmitting the touch signal to the circuit system of the electronic device. When the press function is needed, the user applies pressure to the outer surface of the button 130 with their finger. The button 130 will overcome the reset force of the reset member 140 and move along the first shaft hole 111. The direction of displacement is from the first side to the second side. Thus, the button 130 triggers the switch member 160 through the movement, realizing the press-triggered function. During this process, the first contact surface 1314 and the limiting member 120 will disengage, thereby cutting off the first conductive path during the press process.

[0025] During the above operation, in both the natural and touch states, the first contact surface 1314 of the button 130 remains in contact with the limiting member 120, and the limiting member 120 is sandwiched between the first shaft segment 1311 and the bracket 110. The contact force is provided by the reset member 140, eliminating the need for the limiting member 120 itself to undergo elastic deformation to provide the contact force. In the pressed state, the movement of the button 130 does not cause deformation of the limiting member 120; instead, the first contact surface 1314 of the button 130 will disengage from the limiting member 120. In this technical approach, whether in touch or pressing use, the limiting member 120 used for conductivity will not move or deform, preventing fatigue accumulation and extending its service life.

[0026] In some embodiments, the limiting member 120 in the switch assembly is fitted to the bracket 110. The limiting member 120 has a second shaft hole 121 that faces the first shaft hole 111. The key shaft 131 includes a second shaft segment 1312 that passes through the second shaft hole 121. The first shaft segment 1311 is connected to the second shaft segment 1312, and a first abutment surface 1314 is formed at the end where the first shaft segment 1311 and the second shaft segment 1312 are connected. The diameter of the second shaft hole 121 is smaller than the outer diameter of the first shaft segment 1311 and larger than the outer diameter of the second shaft segment 1312.

[0027] The limiting member 120 is fitted onto the bracket 110 to achieve a tight fit between the limiting member 120 and the bracket 110, forming a robust and stable structure. The limiting member 120 can be fitted and fixed onto the bracket 110 in various ways, such as by screw fixing, snap-fit ​​structure, hot pressing, or adhesive bonding, so that the limiting member 120 will not loosen or fall off during the use of the button 130. Optionally, as shown in Figures 2, 6 to 8, 10, and 13, the switch assembly also includes a fixing post 152. A second mounting groove 113 is provided on the side of the bracket facing the limiting member 120. The limiting member 120 has a first through hole 122 facing the second mounting groove 113. The fixing post 152 passes through the first through hole 122 and is screwed into the second mounting groove 113 to fix the limiting member 120 to the bracket 110, thereby enhancing the structural stability of the assembly.

[0028] The contact surface between the limiting member 120 and the bracket 110 can be precision 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 button 130.

[0029] On the bracket 110, where the limiting member 120 is attached, under the reset force of the resetting member 140, the first abutting surface 1314 of the first shaft segment 1311 forms an abutting force with the side of the limiting member 120 away from the bracket 110 in its natural state, further enhancing the stability of the limiting member 120. This design not only ensures that the limiting member 120 is firmly fixed to the bracket 110, but also further improves the overall stability and durability of the component through the axial force transmission of the first shaft segment 1311. The first abutting surface 1314 of the first shaft segment 1311 forms a tight contact with the side of the limiting member 120 away from the bracket 110. This contact is not a simple support function, but rather, through the transmission of axial force, it makes the limiting member 120 more firmly fixed to the bracket 110, preventing the limiting member 120 from shifting or loosening. Especially during periods of high-pressure pressing, the first contact surface 1314 effectively and evenly transmits the force to the limiting member 120, and through the limiting member 120, the pressure is transmitted to the support 110, which has a load-bearing function. During repeated pressing and resetting, the limiting member 120 can rely on this additional contact force to reduce stress concentration caused by vibration or impact, making the limiting member 120 less prone to damage or wear during long-term use. Even under extreme or high-frequency working conditions, the button 130 and the limiting member 120 can still maintain good performance.

[0030] The diameter of the second shaft hole 121 is smaller than the outer diameter of the first shaft segment 1311. This allows the first shaft segment 1311 to form an effective abutment with the limiting member 120. This design ensures that the contact between the first shaft segment 1311 and the limiting member 120 remains stable during the operation of the button 130, thereby effectively preventing damage or functional instability of the button 130 due to excessive movement. On the other hand, the diameter of the second shaft hole 121 is larger than the outer diameter of the second shaft segment 1312. This design allows the key shaft 131 to move freely axially within the second shaft segment 1312 without interference from the limiting member 120. In other words, the second shaft segment 1312 can smoothly move axially when passing through the second shaft hole 121, ensuring the normal pressing and reset functions of the button 130. Through this structure, the axial movement range of the button 130 is effectively controlled, while ensuring the smooth operation of the button 130 and avoiding problems with the smooth operation of the button 130 caused by excessive friction or uneven movement.

[0031] This embodiment, through the ingenious design of the second shaft hole 121 of the limiting member 120, ensures a balance between limiting and moving the key shaft 131. The key shaft 131 can effectively contact the limiting member 120 when the button 130 is reset, limiting the button 130, while maintaining free axial movement during normal pressing, ensuring the stability and operational comfort of the button 130. This design not only improves the durability of the switch assembly but also optimizes the user experience, ensuring that the button 130 is responsive and reliable over the long term.

[0032] In some embodiments, the diameter 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 extends to the edge of the limiting member 120, forming a notch 123 as shown in FIG. 7. The larger diameter of the first shaft hole 111 ensures that the key shaft 131 can smoothly pass through the entire first shaft hole 111. The slightly smaller maximum outer diameter of the key shaft 131 allows the key shaft 131 to be freely inserted from the first side of the bracket 110, and also ensures that the first shaft segment 1311 can be exposed from the second side during the installation of the button 130. The free movement of the key shaft 131 in the first shaft hole 111 ensures smooth movement of the button 130 assembly, avoiding obstruction or jamming caused by an excessively small first shaft hole 111.

[0033] Since the first shaft segment 1311 abuts against the limiting member 120 during operation, it is impossible for the first shaft segment 1311 to penetrate the second shaft hole 121 of the limiting member 120. Therefore, how to quickly fit the second shaft hole 121 onto the key shaft 131 during assembly becomes a pressing problem. As shown in Figure 10, in this embodiment, the second shaft hole 121 is extended to the edge of the limiting member 120 to form a notch 123, enabling the detachable assembly of the key 130, bracket 110, and limiting member 120. Through this notch 123, the limiting member 120 can move radially during assembly, allowing the second shaft hole 121 of the limiting member 120 to fit onto the second shaft segment 1312 of the key shaft 131, instead of moving axially through the second shaft hole 121. This design greatly simplifies the installation steps of the limiting member 120 and enhances the convenience of later maintenance and replacement by providing detachability.

[0034] The specific assembly process is illustrated in the following example.

[0035] 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 continues to extend from the second side of the bracket 110. At this time, the limiting member 120 has not yet been installed on the bracket 110, 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 the second shaft segment 1312 is also partially exposed outside the bracket 110.

[0036] Step 2, install the limiting member 120. At this time, bring the notch 123 on the limiting member 120 close to the second shaft section 1312. Through the notch 123 on the limiting member 120 that communicates with the second shaft hole 121, move the limiting member 120 radially so that the second shaft hole 121 is fitted onto the second shaft section 1312.

[0037] Step 3: Fix the limiting component 120 to ensure that the limiting component 120 is firmly connected to the bracket 110.

[0038] The assembly process described above requires no complex tools or high-precision operations, facilitating production and assembly. The notch 123 connecting the second shaft hole 121 allows the limiting component 120 to be easily assembled and disassembled, which is crucial for later maintenance and replacement, especially in electronic products that require long-term use or frequent repairs. Through the rationally designed hole diameter fit and shaft segment limiting structure, deviations or misoperations that may occur during assembly are avoided, ensuring accurate fit of each component and thus improving the overall reliability and stability of the product.

[0039] In some embodiments, as shown in Figures 2 and 12, the switch assembly further includes an auxiliary conductive structure 150. When the first contact surface 1314 disengages 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-activated function is required, the user touches the outer surface of the button 130 with their finger. The button 130 does not move, and the first contact surface 1314 and the limiting member 120 remain in contact. At this time, the human body, the first contact surface 1314 of the button 130, and the limiting member 120 form a first conductive path, transmitting the touch signal to the circuit system of the electronic device. When the press function is required, the user applies pressure to the outer surface of the button 130 with their finger. The button 130 overcomes the reset force of the reset member 140 and moves along the first shaft hole 111 in the direction from the first side to the second side. This triggers the corresponding controlled element through the moved button 130, realizing the press-triggered function. During this process, The first contact surface 1314 will disengage from the limiting member 120, thus preventing the first conduction path from being established during the pressing process. In order to enable the button 130 to achieve both the pressing trigger function and the touch conduction function, in this embodiment, when the first contact surface 1314 disengages 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, transmitting the touch electrical signal to the circuit system of the electronic device. When the user stops pressing the button 130, the button 130 will be reset to its natural state under the action of the reset member 140, and the first contact surface 1314 and the limiting member 120 will re-engage.

[0040] In the above working process, in both the natural and touch states, the first abutting surface 1314 of the button 130 remains in contact with the limiting member 120, and the limiting member 120 is sandwiched between the first shaft segment 1311 and the bracket 110. The abutting force is provided by the reset member 140, without the limiting member 120 itself undergoing elastic deformation to provide the abutting force. In the pressed state, the movement of the button 130 does not cause deformation of the limiting member 120; instead, the first abutting surface 1314 of the button 130 and the limiting member 120 will disengage. In this technical means, whether in touch or pressing use, the limiting member 120 will not move or deform, preventing fatigue accumulation and extending its service life. Furthermore, 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, eliminating the need for additional anti-disengagement limiting structures.

[0041] In summary, the switching assembly provided in this embodiment has at least the following four key design advantages.

[0042] First, the limiting component 120 exhibits zero deformation. In its natural state, touch state, and during pressing, the limiting component 120 functions only as a static contact surface or a non-contact structure, requiring no elastic deformation and greatly eliminating the risk of fatigue failure.

[0043] Second, dual touch signal paths ensure stability. In touch mode, button 130 is directly connected to limit member 120 through first contact surface 1314, while in press mode, button 130 is connected to limit member 120 through auxiliary conductive structure 150, ensuring stable operation of the touch function throughout the entire operation cycle.

[0044] Third, the self-limiting structure is simplified. The elasticity of the reset member 140 makes it abut against the first contact surface 1314 and the limiting member 120, thereby achieving axial limiting of the button 130 to prevent the button 130 from falling out. There is no need to set additional limiting components such as buckles or screws, reducing assembly complexity.

[0045] Fourth, the reset component 140 independently bears mechanical stress, while the limiting component 120 only transmits touch electrical signals. The two are functionally separated and each performs its own duties, which significantly improves the overall reliability and service life of the component.

[0046] 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.

[0047] In some embodiments, as shown in Figures 2 and 6 to 8, the auxiliary conductive structure 150 includes a first spring 151 and a fixing post 152 mentioned in the previous embodiments. In this embodiment, the fixing post 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. The fixing post 152 is connected to the limiting member 120 and extends into the bracket 110. When the first contact surface 1314 disengages from the limiting member 120, the second end of the first spring 151 abuts against the fixing post 152. The keycap 132 serves as the operating end of the button 130, allowing the user to touch and press it. At least a portion of the keycap 132 is exposed outside the bracket 110 for the user to touch or press.

[0048] The above embodiment provides a specific implementation of the auxiliary conductive structure 150, which includes a first spring 151 and a fixing post 152. During the pressing of the button 130, the first spring 151 can contact the fixing post 152 to form a second conductive path composed of the keycap 132, the first spring 151, the fixing post 152, and the limiting member 120, thereby transmitting the touch signal to the circuit system of the electronic device. When the button 130 is released, the elastic force of the reset member 140 will cause the button 130 to return to its natural state, ensuring that the first contact surface 1314 re-contacts the limiting member 120.

[0049] In this embodiment, firstly, the auxiliary conductive structure 150 uses a combination of the first spring 151 and the fixed post 152. This ensures that the button 130 will not deform in its natural state, touch state, or during movement, eliminating the risk of fatigue failure and extending its service life. Secondly, the combination of the first spring 151 and the fixed post 152 in this embodiment can participate in forming a second conductive path, ensuring the transmission of touch signals in the pressed state and guaranteeing stable operation of the touch function. Thirdly, due to the deformable nature of the first spring 151, the pressing process of the button 130 can continue even after the first spring 151 abuts against the fixed post 152. The auxiliary conductive structure 150 does not obstruct the pressing displacement of the button 130, ensuring that the displacement of the button 130 can trigger the corresponding components. Furthermore, the design of the auxiliary conductive structure 150 using the first spring 151 and the fixed post 152 is simple, simplifying the structure of the dual-purpose touch and press button, improving reliability, and reducing production costs.

[0050] Based on the above embodiments, as shown in Figures 2 and 11, the bracket 110 has a first mounting groove 112 on the side facing the keycap 132, and a second mounting groove 113 on the side facing the limiting member 120. The first mounting groove 112 and the second mounting groove 113 are connected. The first spring 151 extends into the first mounting groove 112, and the fixing post 152 extends into the second mounting groove 113.

[0051] Through this design, the first spring 151 and the fixing post 152 are fixed in two different directions on the bracket 110, thereby enabling them to stably cooperate with other components and ensuring the stability of the switch assembly 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 correct positions when the button 130 is pressed, avoiding positional displacement 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 conductive path is formed through the fixing post 152 and the limiting member 120 to transmit the touch signal to the circuit system of the electronic device.

[0052] The fixing post 152 not only serves as a fixing component, firmly securing the limiting member 120 to the bracket 110, but also participates in the signal transmission of the second conductive path. The fixing post 152 engages with the second mounting groove 113 via a screw connection, ensuring the stability of signal transmission while guaranteeing the mechanical connection between the limiting member 120 and the bracket 110, thus enhancing the structural stability of the component. When the button 130 is pressed, the fixing post 152 contacts the second end of the first spring 151, participating in the formation of the second conductive path and continuing to transmit the touch signal to the circuit system. Because the fixing post 152 also plays a role in the fixing and installation of the limiting member 120, its design ensures structural stability and prevents the limiting member 120 from loosening or shifting during prolonged use. In other words, the fixing post 152 not only solves the conductive path problem but also addresses the fixing problem of the limiting member 120, simplifying the structural design, improving reliability, and reducing the need for additional fixing components.

[0053] In some embodiments, as a first form of engagement between the first spring 151 and the fixing post 152, the end of the fixing 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 fixing post 152. Thus, in the non-pressed state (including the natural state and the touch state), only the first conduction path is active, while the second conduction path is not activated because the first spring 151 and the fixing post 152 cannot connect. Specifically, when the button 130 is in the natural or touch state, the first conduction path contacts the limiting member 120 through the first abutting surface 1314, transmitting the touch signal to the electronic device's circuitry. At this time, the second conduction path is inactive because the second end of the first spring 151 does not contact the fixing post 152, thus preventing the formation of an effective circuit connection. When the user presses button 130, the first contact surface 1314 disengages from the limiting member 120, interrupting the first conduction path. At this time, the second end of the first spring 151 gradually approaches the fixed post 152 and eventually makes contact with the fixed post 152, thus forming a second conduction path. The second conduction path is then activated and continues to operate, ensuring that touch signals can still be transmitted even when pressed.

[0054] This design, through the switching between the first and second conduction paths, allows for the selective activation of either the first or second conduction path, ensuring the stability and flexibility of touch signal transmission in both pressed and unpressed states. In the unpressed state, only the first conduction path is active, while the second conduction path is inactive, effectively avoiding unnecessary signal transmission interference and maintaining the purity of the touch signal. The ingenious design of the fixing post 152 and the first mounting slot 112 ensures smooth operation of the button 130 in different states, enhancing the overall structural reliability.

[0055] In this embodiment, only the first conductive path operates when the device is not pressed. When the pressing state is activated, the first conductive path is interrupted, and the second conductive path continues to operate through the contact between the first spring 151 and the fixed post 152. This embodiment is applicable to the following operating conditions.

[0056] Scenario a: Applicable to devices that require switching between operation function modes. For example, in smartwatches or fitness trackers, the touch signal in touch mode (first conduction path) is used for the basic first function operation, while the touch signal in press mode (second conduction path) is used to trigger a second different function operation, such as activating the settings interface or enabling special functions. In this case, the transmission of the touch signal in the first conduction path is interrupted when the press begins, and the second conduction path has not yet been activated, which can effectively avoid accidental touches and unnecessary operations, and realize the switching between the two touch functions.

[0057] Case b: Applicable to low-power devices, such as some portable speakers and simple remote controls. In the non-pressed state, the touch signal is transmitted through the first conduction path, while in the pressed state, the touch signal is transmitted through the second conduction path. This achieves the transmission of touch information in both states without consuming excessive power.

[0058] Case c: Applicable to electronic devices with extremely high requirements for signal interference. If the first and second conduction paths are both active, the signal transmission between them may become asynchronous. In the non-pressed state, the second conduction path is not active, effectively avoiding unnecessary signal transmission interference and maintaining the purity of the touch signal.

[0059] As a second form of engagement between the first spring 151 and the fixing post 152, in some embodiments, the end of the fixing post 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 fixing post 152. In this embodiment, in the non-pressed state (including the natural state and the touch state), both the first and second conduction paths are activated. Specifically, when the button 130 is in the natural or touch state, the first conduction path contacts the limiting member 120 through the first abutting surface 1314, transmitting the touch signal to the circuit system of the electronic device. At this time, the second conduction path abuts against the fixing post 152 through the second end of the first spring 151, transmitting the touch signal to the circuit system of the electronic device, forming an effective circuit connection. When the user presses button 130, the first contact surface 1314 disengages 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 post 152. The second conduction path continues to work, ensuring that the touch signal can still be transmitted under the pressing state.

[0060] This design ensures that both the first and second conduction paths are active when not pressed. After a pressing action is initiated, the button 130 and the limiting member 120 remain connected, and the second conduction path is always active. During the switching between touch and pressing actions, the component will not experience any interruption in touch signal transmission.

[0061] In this embodiment, both the first and second conduction paths are active when not pressed. When a pressing action is initiated, the first conduction path is interrupted, while the second conduction path continues to operate, ensuring that the button 130 and the limiting member 120 remain connected. This is particularly suitable for situations requiring stable and continuous touch signal transmission, especially for devices that frequently switch operating modes, ensuring stable operation of the touch signal during high-frequency pressing interactions, allowing the device to process pressing actions without interrupting touch signal transmission. Specific usage examples are as follows.

[0062] Scenario d: When a smartwatch performs medical monitoring, the touch signal is used to monitor health parameters, and the pressing operation is used to physically trigger other functions, such as displaying the screen or selecting menus. During the pressing process, the touch signal needs to be continuously transmitted to continuously monitor health parameters. In this implementation method, the touch signal and the pressing signal work in parallel, which can ensure that the transmission of the touch signal is not interrupted during the pressing process.

[0063] Scenario e: When applied to game control devices (such as gamepads), where rapid and frequent switching between touch and press actions is required, it is necessary to ensure the continuous transmission of touch signals during the switching process, without interrupting the game operation corresponding to the touch signal, and to provide an efficient operating experience.

[0064] It should be noted that the applicability of the above two specific cooperation forms of the first spring 151 and the fixed post 152 depends on the usage of the electronic device and the requirements of the specific operating mode. Those skilled in the art to which this invention pertains can make adaptive adjustments and selections as needed.

[0065] In some applications, when the button 130 of the switch assembly is pressed, it is only for physical triggering and does not need to transmit a touch signal. In order to be compatible with this application through a single component structure, those skilled in the art have made the following improvements: the fixing post 152 is screwed into the first through hole 122 and / or the second mounting groove 113. During the rotation of the fixing post 152, the end of the fixing post 152 has a state in the first mounting groove 112 and a state in the second mounting groove 113.

[0066] In this embodiment, by rotating the fixing post 152, a person with ordinary skill can adjust the position of its end as needed. The fixing post 152 can be screwed in so that its end is flexibly located in the first mounting groove 112 or the second mounting groove 113. This design allows the fixing post 152 to selectively activate the second conduction path when the button 130 is pressed. Specifically, when the end of the fixing post 152 is located in the second mounting groove 113, the end of the first spring 151 located in the first mounting groove 112 cannot extend into the second mounting groove 113 to connect with the fixing post 152, so that the second conduction path is not activated, and pressing only triggers the physical operation of the button 130; conversely, when the end of the fixing post 152 is rotated into the first mounting groove 112, the end of the first spring 151 located in the first mounting groove 112 can achieve abutment cooperation with the fixing post 152, and the second conduction path can be activated. When pressed, not only is the physical triggering function of the button 130 realized, but the touch signal can also be transmitted through the second conduction path to continue to realize the touch conduction function. By rotating the fixing post 152, the operating mode of the switch assembly can be flexibly selected according to actual needs. This allows different functional requirements to be met within the same assembly, simplifying the design, reducing unnecessary functions, and enhancing functionality as needed. This makes the equipment compatible with different usage scenarios, improving the adaptability and customizability of the switch assembly. Furthermore, this design, through screw-connected rotation adjustment, eliminates the need for additional complex switches or adjustment mechanisms, saving design and installation space while maintaining the stability of the button 130's function. As equipment usage and requirements constantly change, those with general knowledge can adjust the position of the fixing post 152 according to specific usage scenarios for flexible configuration, enabling the assembly to be widely used in different products.

[0067] The rotation function of the fixed post 152 can be achieved by screwing it only into the first through hole 122, by screwing it only into the second mounting groove 113, or by simultaneously screwing it into both the first through hole 122 and the second mounting groove 113. The last method is preferred, in which case the fixed post 152 is screwed into both the first through hole 122 and the second mounting groove 113. In addition to achieving the aforementioned technical effects, it can also simultaneously achieve the technical effect of fixing the limiting member 120 onto the bracket 110.

[0068] It should be noted that, as shown in Figures 2, 8 and 11, those skilled in the art can use one of the springs serving as the reset element 140 as the first spring 151 as needed, so that it can perform the reset function and cooperate with the fixed post 152 to form a first conductive path. Similarly, the third mounting groove 115 used to accommodate the reset element spring can be used as the first mounting groove 112 used to accommodate the first spring 151.

[0069] In some embodiments, as shown in FIG9, the key shaft 131 of the switch assembly includes a first shaft segment 1311, a second shaft segment 1312, and a third shaft segment 1313, which are arranged sequentially. The second shaft hole 121 is sleeved on the second shaft segment 1312. One end of the first shaft segment 1311 facing the limiting member 120 protrudes radially from the second shaft segment 1312 to form a first abutment surface 1314, and one end of the third shaft segment 1313 facing the limiting member 120 protrudes radially from the second shaft segment 1312 to form a second abutment surface 1315. In this embodiment, the key shaft 131 of the switch assembly is formed by the first shaft segment 1311, the second shaft segment 1312, and the third shaft segment 1313 arranged sequentially to form a multi-segment structure. In its natural state, or when the user touches button 130, the first contact surface 1314 contacts the limiting member 120, forming a first conductive path to transmit the touch signal to the electronic device's circuitry. At this time, the second conductive path is not activated. When the user presses button 130, the first contact surface 1314 disengages from the limiting member 120, interrupting the first conductive path. The second contact surface 1315 gradually approaches and contacts the limiting member 120 on the side facing the bracket 110, thus forming a second conductive path composed of button 130, the second contact surface 1315 of button 130, and the limiting member 120, continuing to transmit the touch signal to the circuitry, ensuring the transmission of the touch signal in the pressed state. In this case, the second contact surface 1315 acts as an auxiliary conductive structure 150.

[0070] It is not difficult to see that in the above embodiment, the second abutment surface 1315 is the limiting surface of the limit position of the button 130 in the pressed state. That is, when the second abutment surface 1315 abuts against the limiting member 120, the button 130 is blocked by the limiting member 120 and cannot continue to move. At this time, the second conduction path can only be activated when the button 130 moves to the limit position. The condition is too harsh and limits the applicability of the switch assembly. Based on this, as shown in FIG12, on the basis of the above embodiment, the auxiliary conductive structure 150 includes a second spring 153 sleeved on the second shaft segment 1312. The first end of the second spring 153 is connected to the second abutment surface 1315. After the first abutment surface 1314 disengages from the limiting member 120, the second end of the second spring 153 can abut against the side of the limiting member 120 facing the keycap 132.

[0071] The above embodiment provides another specific implementation of the auxiliary conductive structure 150, namely, the auxiliary conductive structure 150 includes a second spring 153. During the pressing of the button 130, the second spring 153 can contact the limiting member 120 to form a second conductive path composed of the keycap 132, the second abutment surface 1315, the second spring 153, and the limiting member 120, thereby transmitting the touch signal to the circuit system of the electronic device. When the button 130 is released, the elasticity of the reset member 140 will cause the button 130 to return to its natural state, ensuring that the first abutment surface 1314 re-contacts the limiting member 120.

[0072] In this embodiment, firstly, the auxiliary conductive structure 150 selects the second spring 153 to cooperate with the limiting member 120. The limiting member 120 will not deform under natural conditions, touch conditions, or during movement, thus eliminating the risk of fatigue failure and extending its service life. Secondly, the cooperation between the second spring 153 and the limiting member 120 in this embodiment can participate in forming a second conductive path, ensuring the transmission of touch signals under pressure and ensuring stable operation of the touch function under pressure. Thirdly, due to the deformable nature of the second spring 153, the pressing process of the button 130 can continue even 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 button 130, ensuring that the displacement of the button 130 can trigger the corresponding components. With the deformability of the second spring 153, the second conductive path can be activated during part or all of the pressed stroke of the button 130. In addition, the auxiliary conductive structure 150 uses a second spring 153, which has a simple design, simplifies the structure of the touch and press dual-use button, improves reliability, and reduces production costs.

[0073] As a first form of engagement 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 is separated from the limiting member 120. Thus, in the non-pressed state (including the natural state and the touch state), only the first conducting path is active, while the second conducting path is not activated because the second spring 153 and the limiting member 120 cannot connect. Specifically, when the button 130 is in the natural or touch state, the first conducting path contacts the limiting member 120 through the first abutting surface 1314, transmitting the touch signal to the electronic device's circuitry. At this time, the second conducting path is inactive because the second end of the second spring 153 does not contact the limiting member 120, thus preventing the formation of an effective circuit connection. When the user presses button 130, the first contact surface 1314 disengages from the limiting member 120, interrupting the first conduction path. At this time, the second end of the second spring 153 gradually approaches the limiting member 120 and eventually makes contact with the limiting member 120, thus forming a second conduction path. The second conduction path is then activated and continues to operate, ensuring that touch signals can still be transmitted even when the button is pressed.

[0074] This design, through the switching between the first and second conduction paths, allows for the selective activation of either the first or second conduction path, ensuring the stability and flexibility of touch signal transmission in both pressed and unpressed states. In the unpressed state, the second conduction path is inactive, effectively avoiding unnecessary signal transmission interference and maintaining the purity of the touch signal. In this embodiment, only the first conduction path operates in the unpressed state; when the pressed state is activated, the first conduction path is interrupted, and the second conduction path continues to operate through the contact between the second spring 153 and the limiting member 120. This design is also applicable to the operating conditions a, b, and c described above, and will not be repeated here.

[0075] As a second form of engagement 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-pressed state (including the natural state and the touch state), both the first and second conduction paths are activated. Specifically, when the button 130 is in the natural or touch state, the first conduction path contacts the limiting member 120 through the first abutting surface 1314, transmitting 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, transmitting the touch signal to the circuit system of the electronic device, forming an effective circuit connection. When the user presses button 130, the first contact surface 1314 disengages from the limiting member 120, interrupting the first conduction path. At this time, the second spring 153, after being compressed and deformed, can more stably abut against the limiting member 120, and the second conduction path continues to work, ensuring that touch signals can still be transmitted in the pressed state. This design ensures that in the non-pressed state, both the first and second conduction paths are working. After the pressing action is initiated, button 130 and limiting member 120 remain connected, and the second conduction path is always in working condition. During the switching between touch and pressing actions, the component will not experience a break in touch signal transmission.

[0076] In this embodiment, both the first and second conduction paths are active when not pressed. When a pressing action is initiated, the first conduction path is interrupted, while the second conduction path continues to operate, ensuring that the button 130 and the limiting member 120 remain connected. This is particularly suitable for situations requiring stable and continuous touch signal transmission, especially for devices that frequently switch operating modes, ensuring stable operation of the touch signal during high-frequency pressing interactions, allowing the device to process pressing actions without stopping touch signal transmission. Specific usage examples can be found in the descriptions of situations d and e above, and will not be repeated here.

[0077] In some embodiments, as shown in Figures 6 to 8, 10, and 13, the limiting member 120 includes a first limiting piece 124 and a second limiting piece 125 arranged at an angle. The first limiting piece 124 is fixed on the bracket 110. The button 130 is movably disposed on the bracket 110 to achieve contact or separation with the first limiting piece 124. The second limiting piece 125 is used to connect to the second circuit board 200 through a conductive connector. During the movement of the button 130 relative to the bracket 110, it is in contact with the first limiting piece 124. When the button 130 is touched, the button 130, the first limiting piece 124, the second limiting piece 125, and the conductive connector 700 sequentially transmit touch electrical signals to form a first conductive path, thereby transmitting the touch signal to the second circuit board 200. In related technologies, conductive connectors typically employ conductive springs, which generally include a fixed portion and an elastic portion. The fixed portion is used for fixed connection with structures such as circuit boards, achieving connection with their internal circuitry. The elastic portion is used for non-fixed pressure connection with external circuitry, specifically relying on the deformation of the elastic portion to achieve contact with the external circuitry. When the conductive spring is installed, external force is required to deform the elastic portion to obtain sufficient elastic force so that the elastic portion can stably press against the external circuitry. However, in related technologies, the elastic portion of the conductive spring is in an undeformed state before installation. During installation, the undeformed elastic portion needs to be adjusted to a deformed state that generates sufficient elastic force. This process requires a large deformation of the elastic portion, leading to a cumbersome operation. Based on this, the present invention also provides an optimized conductive connector.

[0078] As shown in Figures 14 to 16, the main structure of the conductive connector 700 provided in this embodiment of the invention includes a first substrate 710, a wing plate 720, and an elastic sheet 730. The back side of the first substrate 710 is configured to connect to a circuit board; this description uses the connection between the back side of the first substrate 710 and the second circuit board 200 as an example. Two wing plates 720 are provided, each extending from opposite sides of the first substrate 710 toward 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 bent section 733, and a second elastic arm 734 arranged sequentially. The vertical plate 731 is connected to the first substrate 710, and the bent section... 733 is located at the end of the elastic piece 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 bent section 733 toward the first substrate 710 and extends 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 toward the first substrate 710 so that the elastic piece 730 is in a deformed state. The restoring force generated by the elastic piece 730 makes the second limiting portion 750 always have a tendency to move away from the first substrate 710.

[0079] The first substrate 710 is the core component of the conductive connector 700. The first substrate 710 completes the electrical connection with the second circuit board 200 through its back side, ensuring the stability and reliability of the connection between the conductive connector 700 and the second circuit board 200.

[0080] The design of the wing plate 720 not only enhances the stability of the structure, but also ensures that the elastic plate 730 can maintain the preset deformation state in its natural state through its cooperation with the elastic plate 730.

[0081] The upright plate 731 of the elastic sheet 730 is connected to the first substrate 710, serving as a support and connection; the first elastic arm 732 is connected to the upright plate 731, has elasticity, and is responsible for providing deformation capability for the elastic sheet 730 during installation; the bent section 733 is located at the end of the elastic sheet 730 away from the first substrate 710, protruding from the free end of the wing plate 720, and is used for contact connection with devices of the external circuit structure. The bent section 733 enables the conductive connector 700 to make electrical contact with external circuits (such as sensors, connectors, conductive parts, etc.); the second elastic arm 734 extends from the bent section 733 toward the first substrate 710 and enters between the wing plates 720, and is used to abut against the front of the first substrate 710 when necessary to deform and provide further elastic force.

[0082] 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 deformation state in its natural state, ensuring that the elastic sheet 730 remains in a stable elastic state when it is not subjected to external force.

[0083] In this embodiment, the design utilizes the cooperation of the first limiting part 740 and the second limiting part 750 to maintain the elastic sheet 730 in a preset deformation state under natural conditions. During installation, 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 of the first substrate 710 and the second circuit board 200 form a stable connection. At this time, the elastic sheet 730 is already in a preset deformation state due to the cooperation of the first limiting part 740 and the second limiting part 750; Step 2, apply external force to the elastic sheet 730 to further slightly deform the elastic sheet 730, causing the second limiting part 750 to disengage from the first limiting part 740 and move closer to the first substrate 710, so that the bent section 733 of the elastic sheet 730 gradually approaches the first substrate 710 to achieve the final installation state. After the elastic sheet 730 undergoes slight deformation in the second step, it can form a stable contact with the external structure through the bending section 733, ensuring reliable electrical connection of the conductive connector 700.

[0084] In this embodiment, through the cooperation of the first limiting part 740 and the second limiting part 750, the elastic sheet 730 is already maintained in a preset deformation state in its natural state. Only a small further deformation of the elastic sheet 730 is needed to obtain the required elastic resistance. Compared to the unrestrained elastic sheet 730 in its natural state, the deformation adjustment during installation is smaller, reducing the number of steps requiring larger deformation in traditional technologies, making the installation process simpler and more efficient. Furthermore, because the elastic sheet 730 is already maintained in a suitable deformation state in its natural state, the deformation during installation is smaller, thereby reducing repeated bending and deformation adjustment of the material and extending the service life of the conductive connector 700.

[0085] As the size of electronic products continues to decrease, the integration of their internal structures is also constantly increasing. This means that the operable space inside the product is becoming increasingly limited, requiring minimal external tools and adjustments during installation. Traditional installation methods often require significant deformation or external force to complete the installation. However, in this embodiment, through the cooperation of the first limiting part 740 and the second limiting part 750, the elastic sheet 730 is already in a preset deformation state in its natural state. Only external force needs to be applied to make the elastic sheet 730 deform slightly further and complete the installation, without the need for significant deformation and adjustment, thus avoiding the need for a large amount of space for operation in traditional installation methods. Adapting to the trend of miniaturization and thinning of various electronic products, the design of the conductive connector 700 not only needs to ensure the stability of the electrical connection, but also fully considers the compactness and integration of the internal structure of the conductive electronic product. Therefore, traditional installation methods often face the problems of limited space and inconvenient operation. This embodiment, by optimizing the deformation and adjustment method of the elastic sheet 730, precisely meets these new requirements.

[0086] In some embodiments, as shown in the figure, the upright 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, the bending directions of the first bending segment 735 and the second bending segment 736 being opposite.

[0087] The continuously arranged first bending segment 735 and the second bending segment 736 with opposite bending designs effectively disperse deformation stress, allowing the elastic sheet 730 to be subjected to external forces more evenly during operation. Compared with traditional designs, the continuous reverse bending design allows the elastic sheet 730 to achieve ideal deformation under smaller forces, thereby enhancing the overall elastic performance. The opposite bending directions of the first bending segment 735 and the second bending segment 736 provide mutually counteracting elastic forces, which not only allow the elastic sheet 730 to maintain a certain degree of flexibility under different deformation states, but also optimize the deformation response of the elastic sheet 730. This is beneficial to enhancing the deformation and recovery capabilities of the conductive connector 700. The deformation force during installation is small, and the elastic sheet 730 can quickly return to the initial state where the first limiting part 740 and the second limiting part 750 abut against each other after the external force is removed.

[0088] In some embodiments, as shown in the figure, a protruding lug 760 is formed on the wing 720 of the conductive connector 700, which shields the first bent segment 735 and / or the second bent segment 736. Since the bent segment is typically the most susceptible to fatigue damage in the elastic sheet 730, especially during high-frequency deformation or installation, it is prone to cracking, bending, or excessive wear. Therefore, it is necessary to prevent physical impact from external structures on the bent segment. The protruding lug 760, through its physical shielding effect, effectively reduces the possibility of the bent segment directly contacting external objects, avoiding direct impact and damage to these vulnerable components from external factors. This not only improves the service life and stability of the conductive connector 700 but also reduces maintenance costs.

[0089] In some embodiments, as shown in the figure, an ear plate 760 on one of the wing plates 720 is bent toward 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 an external circuit through the second substrate 770. This design provides multiple connection methods, allowing users to select the appropriate connection method according to different application requirements, thus making the conductive connector 700 more widely applicable.

[0090] Similar to the first substrate 710, the second substrate 770 is a non-elastic structure. Compared to the dynamic compression connection provided by the elastic sheet 730 and the first substrate 710, the second substrate 770 and the first substrate 710 provide a static connection method. Through the second substrate 770, the conductive connector 700 can complete the electrical connection without relying on elastic deformation, suitable for applications requiring high connection stability. The first substrate 710 and the second substrate 770 can be used separately for static connections between two circuit boards, making the product more flexible and allowing for the selection of different connection methods according to needs. The design of the second substrate 770 increases connection stability, especially under conditions requiring high mechanical stress. As a non-elastic structure, the second substrate 770 effectively prevents poor electrical contact caused by deformation of the connection points, thereby improving the service life and electrical performance of the entire conductive connector 700.

[0091] The engagement of the elastic sheet 730 with the first substrate 710 is primarily for achieving a compression contact connection between the second circuit board 200 and the external circuit structure. This compression contact connection provides more stable electrical contact during installation, ensuring connection reliability. The static connection function of the second substrate 770 offers another option, making the connection method more flexible. By providing dual connection methods with the elastic sheet 730 and the second substrate 770, the optimal connection method can be selected according to specific needs during installation. For example, if maintaining strong physical connection strength during installation is required, the static connection method of the second substrate 770 would be a preferred approach. For applications requiring dynamic connection or higher flexibility, the engagement of the elastic sheet 730 with the first substrate 710 can be selected. Users can flexibly choose the appropriate connection method according to specific needs, ensuring both the reliability of the electrical connection and improving the product's adaptability to meet the requirements of different environments.

[0092] 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 part 740. The fit between the first limiting part 740 and the second limiting part 750 requires a certain mechanical support, especially in the initial state, when the elastic sheet 730 is constrained to a preset deformation state, and the first limiting part 740 and the second limiting part 750 are always in contact, the first limiting part 740 will bear a certain pressure or stress. Providing a reinforcing rib 780 can effectively enhance the structural strength of the first limiting part 740, thereby preventing it from deforming, being damaged or failing due to fatigue during the stress process, and maintaining stability for a longer period of time.

[0093] In some embodiments, as shown in the figure, a stress-relieving hole 790 is formed at the connection between the wing plate 720 and the first substrate 710. In conventional structural designs, connections or bends often become stress concentration areas, which can lead to material fatigue, cracking, or failure under long-term stress. By providing a stress-relieving hole 790 at the connection between the wing plate 720 and the first substrate 710, the presence of the stress-relieving hole 790 allows stress to be evenly distributed along the hole wall, avoiding the localized stress concentration phenomenon in conventional designs. This effectively disperses stress, reduces stress concentration at the connection, and thus reduces the risk of damage to the component during use. The design of the stress-relieving hole 790 also allows the component to achieve a lighter weight and lower material cost.

[0094] In practical use, the bent section 733 of the conductive connector 700 in the aforementioned 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, through contact with the bent section 733 of the conductive connector 700, physically contacts the elastic piece 730, causing the elastic piece 730 to be compressed and deformed, thus achieving a compression 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 side, ensuring a stable electrical connection between the circuit system and the switching assembly. The bent section 733 of the elastic sheet 730 of the conductive connector 700 abuts against the second limiting piece 125 of the limiting member 120. Under the pressure of the second limiting piece 125, the elastic sheet 730 undergoes further deformation relative to its initial uninstalled state, causing the first limiting portion 740 and the second limiting portion 750 to separate, thus achieving a stable connection between the elastic sheet 730 and the second limiting piece 125. The conductive connector 700 connects the limiting member 120 to the second circuit board 200 of the electronic device's internal circuitry, enabling the transmission of touch signals under touch functionality to the electronic device's circuitry.

[0095] The design of the conductive connector 700 allows the elastic sheet 730 to achieve a stable electrical connection with only slight deformation adjustment during installation. The amount of deformation adjustment during installation is smaller, reducing the number of operation steps that require a large amount of deformation in traditional technology, making the installation process simpler and more efficient.

[0096] In some embodiments, as shown in Figures 2, 6 to 8, and 10 to 13, the bracket 110 has a positioning protrusion 119 formed on the side facing the first limiting piece 124, and the first limiting piece 124 has a second through hole 126 that matches and connects with the positioning protrusion 119. The cooperation between the positioning protrusion 119 and the second through hole 126 is used to ensure that the limiting member 120 is quickly positioned when assembled to the bracket 110, avoiding deviation or misalignment. The specific installation steps are as follows: First, fit the second through hole 126 onto the positioning protrusion 119 to ensure that the limiting member 120 fits against the surface of the bracket 110. Through this fit, the second through hole 126 of the limiting member 120 is precisely positioned in the predetermined position of the bracket 110 during the initial assembly. Then, after ensuring that the second through hole 126 fits onto the positioning protrusion 119, gently rotate the first limiting piece 124 around the positioning protrusion 119 until the first through hole 122 is aligned with the second mounting groove 113. At this time, the limiting member 120 is in the correct angle and position, preparing for the next fixing step. Finally, after the first through hole 122 is aligned with the second mounting groove 113, insert the fixing post 152 into the first through hole 122 and the second mounting groove 113, and screw the fixing post 152 into the second mounting groove 113 to complete the stable fixing of the limiting member 120.

[0097] The engagement of the positioning protrusion 119 and the second through hole 126 ensures that the auxiliary limiting component 120 is precisely fixed in the predetermined position during installation, preventing deviations during assembly and improving assembly accuracy. This design allows the limiting component 120 to be accurately aligned with the correct position through a simple rotation operation, eliminating the need for complex adjustments or additional tools. This reduces positional errors during adjustment and inspection during assembly, thereby improving overall assembly efficiency. The engagement of the positioning protrusion 119 and the second through hole 126 not only ensures accurate initial positioning but also enables the limiting component 120 to achieve a dual-point fixation effect through the positioning protrusion 119 and the fixing post 152 after installation, enhancing the stability of the connection.

[0098] The present invention also protects a wearable electronic device, which includes the switching assembly provided in the foregoing embodiments of the present invention.

[0099] Specifically, as shown in Figures 1 to 6, the main structure of wearable electronic devices also includes a middle frame 300, a bottom shell 400, and a first circuit board 500.

[0100] In a wearable electronic device, a button hole 310 is provided on the middle frame 300, which passes through the inner and outer sides of the middle frame 300; a bottom shell 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 shell 400; a first circuit board 500 is disposed between the fixing seat 410 and the switch 160; the switch 160 is connected to the first circuit board 500; the switch assembly is installed in the button hole 310 and is configured to trigger the switch 160 by pressing the switch assembly.

[0101] The middle frame 300 serves as the external frame structure of the electronic device, while the bottom shell 400 connects to the middle frame 300 and encloses the back of the electronic device. Together, the middle frame 300 and the bottom shell 400 support and protect the various internal components of the wearable electronic device, protecting the internal circuits and components. A button hole 310, penetrating both the inner and outer sides, is provided on the middle frame 300 to accommodate and fix the pressing component. The shape and size of the button hole 310 are determined according to the design requirements of the pressing component to ensure smooth installation and fixation of the pressing component and to accommodate pressing actions.

[0102] The first circuit board 500 is mounted on the mounting base 410, and the switch 160 is connected to the first circuit board 500. The switch 160 is a key component in the electronic device used to receive physical pressure and transmit electrical signals to the first circuit board 500 after being triggered by pressure. Since the mounting base 410 is integrated into the bottom shell 400 and directly connected to the first circuit board 500, the fixing of the switch 160 becomes simpler and more secure. The switch assembly is installed in the button hole 310. When the user presses the button assembly, a partial mechanism actuates, ultimately triggering the switch 160 by pressing. In this design, the first circuit board 500 is disposed between the fixing base 410 and the switch 160. The side of the switch 160 that is directly pressed by the pressing component is designated as the front side of the switch 160. An electrical connection can be formed between the back side of the switch 160 and the first circuit board, which serves as a connection point. Since the first circuit board 500 is sandwiched between the fixing base 410 and the back side of the switch 160, after the front side of the switch 160 is physically pressed by the pressing component, the first circuit board 500 is squeezed and forms a more stable contact connection with the switch 160. Compared to leading out a connection point from the side of the switch to connect with the circuit board, there is no need to set up a related elastic conductive structure for transition connection, which simplifies the product structure and reduces the cost of processing and assembly.

[0103] Furthermore, related technologies include methods that integrate both the mounting base and the switch component onto the switch assembly, with the first circuit board sandwiched between the mounting base and the back of the switch component. While this can achieve a stable connection between the first circuit board and the switch component under frequent pressure, it makes the structure of the switch assembly overly complex. This limits the connection position and method between the switch component and the first circuit board to the specific structure of the pressing assembly, resulting in adverse effects. In this invention, by placing the mounting base on the bottom shell, the internal space of the electronic device and the laying requirements of the first circuit board within the electronic device can be fully utilized, the position of the mounting base can be reasonably set, and the result of the switch assembly will not be overly complicated.

[0104] In some embodiments, the base 400 and the mounting base 410 are integrally formed, with the mounting base 410 located inside the middle frame 300 and directly opposite the button hole 310. The mounting base 410 is manufactured using an integral molding method, ensuring structural stability and reducing the number of components, thus avoiding the need for additional switch mounting brackets in traditional designs. Therefore, this design simplifies the manufacturing process and reduces processing and assembly costs.

[0105] In summary, the above embodiments of the present invention, by integrally molding the mounting base 410 into the bottom shell 400, eliminate the need for a separate mounting bracket to fix the switch component 160. Firstly, this 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 during production, thus reducing production costs and assembly difficulty. Secondly, the integrally molded mounting base 410 provides stable support, avoiding the loosening or wear problems that may occur in traditional designs due to unstable assembly of the switch mounting bracket. This is particularly suitable for modern consumer electronic devices, especially products such as smartwatches that have high requirements for miniaturization and thinness.

[0106] Preferably, the switch 160 is bonded to the first circuit board 500 using surface mount technology (SMT). SMT is used to directly mount electronic components onto the surface of a circuit board, rather than connecting them through traditional pin insertion holes. The application of SMT can significantly improve production efficiency, reduce space occupation, and allow for more precise control of connection quality during manufacturing. Bonding the switch 160 to the first circuit board 500 using SMT enables high-precision mounting, reduces human error, and greatly improves mounting efficiency due to the use of automated equipment. In traditional processes, the switch 160 may require insertion through pins into the circuit board or other connection methods, which occupies more board space. Using SMT, the switch 160 is directly bonded to the circuit board surface, improving space utilization and making the overall circuit board design more compact, meeting the demands of increasingly miniaturized and thinner electronic devices. SMT offers high automation and precision, making the bonding process more stable and reliable. High-temperature soldering (such as reflow soldering) ensures a strong and durable connection between the switch 160 and the first circuit board 500. This robust connection effectively reduces the risk of switch components 160 falling off or making poor contact during use, thereby improving the long-term stability of the product.

[0107] The steps for bonding the switch component 160 to the first circuit board 500 via SMT process can be described as follows: First, the switch component 160 is pre-treated to adapt to the SMT process. A layer of solderable material can be coated on the back contact surface of the switch component 160 to ensure soldering quality. Then, using SMT equipment, the switch component 160 is precisely mounted to the designated position on the first circuit board 500. The SMT equipment utilizes surface mount technology for precise component positioning and soldering, and the switch component 160 is directly bonded to the surface of the first circuit board 500. Then, through a reflow soldering process, the back pads of the switch component 160 are connected to the pads on the first circuit board 500. During the reflow soldering process, the solder material is heated and melted to form a reliable electrical connection. Finally, after mounting and soldering 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 that there are no soldering defects or poor contact.

[0108] In some embodiments, the first circuit board 500 is a flexible circuit board. Flexible circuit boards have good flexibility and bendability, making them suitable for electronic devices that require higher integration and compact design. However, due to the thinness and flexibility of flexible circuit boards, they may undergo certain bending deformation when subjected to external stress and physical pressure, which may affect the stability and reliability of the circuit. To overcome this problem and further optimize the stability and durability of the product, as shown in Figures 2 and 6, this embodiment provides a reinforcement design, namely, a reinforcement plate 600 is provided between the first circuit board 500 and the fixing base 410.

[0109] The reinforcing plate 600 is typically made of a high-rigidity material (such as metal or rigid plastic) with sufficient rigidity and strength to prevent the flexible circuit board from being affected by pressure or bending deformation during prolonged use, thus protecting its electrical performance or preventing damage. The design of the reinforcing plate 600 can be customized according to the specific shape, size, and installation space requirements of the first circuit board 500. The reinforcing plate 600 and the first circuit board 500 are installed in a close-fitting manner, forming a support structure between the reinforcing plate 600 and the flexible circuit board. This ensures that the flexible circuit board remains flat under external forces, reducing poor contact or breakage caused by bending or pressure. The reinforcing plate 600 effectively enhances the rigidity of the flexible circuit board, preventing damage or poor connection due to bending or external forces during use, thus improving the reliability of the first circuit board 500.

[0110] In some embodiments, as shown in Figures 2 and 6, the mounting base 410 includes a first upright plate 411 and a second upright plate 412 connected vertically. The first upright plate 411 is positioned directly opposite the button hole 310. The surface of the reinforcing plate 600 away from the switch assembly is attached to the first upright plate 411. One side of the reinforcing plate 600 and the first circuit board 500 abuts against the second upright plate 412. Specifically, the first upright plate 411 is positioned directly opposite the button hole 310 to provide a stable support surface for the switch assembly. The position and shape of the button hole 310 are precisely designed to ensure that the pressing assembly can accurately mate with the switch element 160 and trigger the corresponding signal after assembly. The bonding connection between the reinforcing plate 600 and the first upright plate 411 is the key to achieving structural stability. One side of the reinforcing plate 600 is bonded to the first upright plate 411, while the other side of the reinforcing plate 600 is tightly fitted to the first circuit board 500. In this way, the reinforcing plate 600 is supported by the first upright plate 411, avoiding deformation or stress concentration that may occur during the use of the flexible circuit board. 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.

[0111] During the operation of the switch assembly, when the user presses the switch assembly, the resulting pressing force acts directly on the switch element 160 through the switch assembly, and is then transmitted to the first upright plate 411 through the first circuit board 500 and the reinforcing plate 600. The first upright plate 411 becomes the final pressure-bearing structure, bearing all the pressure from the switch assembly. Therefore, the first upright plate 411 must have sufficient strength and rigidity to ensure that it will not deform or be damaged during the pressing process. The second upright plate 412 is perpendicularly connected to the first upright plate 411. This perpendicular connection structure design greatly enhances the mechanical stability of the first upright plate 411 when bearing pressing force. Specifically, the bottom shell 400, the first upright plate 411, and the second upright plate 412 form a spatially stable three-dimensional structure 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.

[0112] Another function of the second upright plate 412 is to provide an additional positioning surface for the reinforcing plate 600 and the first circuit board 500, so that the thickness side of the reinforcing plate 600 and the first circuit board 500 can stably abut against the second upright plate 412. The second upright plate 412 is used to position the reinforcing plate 600 and the first circuit board 500 in the direction perpendicular to the second upright plate 412. Through the vertical connection of the first upright plate 411 and the second upright plate 412, the entire fixing base 410 can position the reinforcing plate 600 and the first circuit board 500 in both directions perpendicular to the first upright plate 411 and perpendicular to the second upright plate 412, thereby improving the assembly efficiency of the components, making the assembly more precise, greatly simplifying the traditional complex assembly process, and improving production efficiency.

[0113] In some embodiments, the bracket 110 is embedded in the button hole 310 and fixedly connected to the middle frame 300. The fixed connection between the bracket 110 and the middle frame 300 enhances connection stability and sealing. As the main support structure of the electronic device, the fixed connection between the middle frame 300 and the bracket 110 ensures the stability of the pressing component. During the operation of the button 130, the bracket 110, as a load-bearing structure, effectively distributes some of the pressure borne by the button 130 to the middle frame 300. Because the bracket 110 is fixedly connected to the middle frame 300, the sealing effect at the connection point is enhanced, preventing external dust and moisture from entering the wearable electronic device through the gap between the bracket 110 and the middle frame 300. This helps improve the protective capabilities of the wearable electronic device, especially in terms of water tightness and dust resistance, ensuring stable operation under different environmental conditions and improving the overall durability and reliability of the electronic device.

[0114] In some embodiments, the bracket 110 is glued to the button hole 310 of the middle frame 300 using an adhesive dispensing process. This dispensing process involves applying adhesive to the interface where the bracket 110 contacts the middle frame 300, creating a strong connection between them. The adhesive dispensing process is simple to operate and highly efficient, ensuring a tight seal and stability between the bracket 110 and the middle frame 300. Furthermore, the type of adhesive can be adjusted according to the specific needs of the electronic device to ensure it is not prone to aging or detachment during long-term use.

[0115] The dispensing process eliminates the need for complex mechanical connections or additional fasteners, enabling stable connections in a short time and reducing labor costs and assembly cycles during production. Through dispensing, a thin, uniform sealant layer is formed on the contact surface between the bracket 110 and the button hole 310, further enhancing the electronic device's waterproof and dustproof capabilities, especially in harsh environments, preventing dust and moisture from penetrating the device. The dispensing process provides sufficient adhesive strength to ensure a firm fixation between the bracket 110 and the middle frame 300, preventing loosening or displacement during use and improving the device's stability and reliability. The adhesive is evenly distributed on the contact surface between the bracket 110 and the middle frame 300 during dispensing, helping to disperse the pressure generated during button 130 operation, reducing localized stress concentration, and thus extending the lifespan of the button 130.

[0116] In some embodiments, as shown in Figures 3, 7, and 11 to 12, the button hole 310 includes a first hole segment 311 near the inner side and a second hole segment 312 near the outer side. The cross-section of the first hole segment 311 is smaller than the cross-section of the second hole segment 312. A first stop surface 313 facing outward is formed between the first hole segment 311 and the second hole segment 312. The bracket 110 includes a first bracket segment 116 adapted to the first hole segment 311 and a second bracket segment 117 adapted to the second hole segment 312. A second stop surface 118 facing the first stop surface 313 is formed between the first bracket segment 116 and the second bracket segment 117. When the bracket 110 is fitted into the button hole 310, the first stop surface 313 and the second stop surface 118 abut against each other.

[0117] When the first bracket segment 116 and the second bracket segment 117 of the bracket 110 are precisely fitted with the first hole segment 311 and the second hole segment 312 of the button hole 310, the first stop surface 313 and the second stop surface 118 cooperate with each other, thereby ensuring a tight connection between the bracket 110 and the middle frame 300, effectively avoiding loosening or misalignment during assembly, and improving connection stability. The mating design formed by the first stop surface 313 and the second stop surface 118 can automatically complete positioning when the bracket 110 is installed into the button hole 310, without the need for additional fasteners or complex assembly operations. In this way, the installation of the bracket 110 is simpler, avoiding errors or positional deviations that may occur in traditional installation methods, and improving overall assembly efficiency compared with traditional manual positioning and alignment processes. Through the surface contact of the first stop surface 313 and the second stop surface 118, the bracket 110 effectively disperses the impact force during the pressing of the button 130, reducing the loosening or deformation of the bracket 110 due to force concentration, and enhancing the durability and stability of the overall structure.

[0118] In the actual assembly process, one end of the first bracket section 116 of the bracket 110 is first inserted into the outside of the button hole 310. After the bracket 110 is fully inserted into the button hole 310, the first stop surface 313 and the second stop surface 118 abut against each other, and at this time the precise positioning between the bracket 110 and the middle frame 300 is completed. In this process, the stop surfaces help the bracket 110 to be stably positioned within the middle frame 300 through contact and engagement, avoiding possible positional deviations or loosening during assembly, and ensuring a firm connection between the bracket 110 and the button hole 310.

[0119] Based on the above embodiment, the outer contour of one end of the second bracket segment 117 connected to the first bracket segment 116 is recessed to form a dispensing segment 1171. When the bracket 110 is fitted into the button hole 310, the dispensing segment 1171, the first stop surface 313, and the inner wall of the second hole segment 312 together form 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 contained, thereby ensuring that the dispensing process can more accurately and evenly distribute the glue 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 strength between the bracket 110 and the middle frame 300, avoiding loosening or separation caused by uneven dispensing or weak bonding. In traditional assembly, the dispensing process requires additional tools or complex operations. By designing dispensing segments 1171 and forming dispensing grooves 170 on the bracket 110, the dispensing process can be made more automated and convenient. Operators only need to pre-place the dispensing material in the dispensing segments 1171, eliminating the need for precise alignment and manual application, thereby improving assembly efficiency. The adhesive bonding provided by the dispensing segments 1171 and the dispensing grooves 170 not only enhances the connection strength between the bracket 110 and the middle frame 300, but also effectively absorbs the impact force generated during pressing, reducing localized damage caused by force concentration and improving the product's impact resistance during use.

[0120] The specific assembly process can be illustrated as follows: First, apply an appropriate amount of adhesive material to the dispensing section 1171 area 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 section 1171 of the bracket 110, the inner wall of the second hole section 312 in the button hole 310, and the first stop surface 313. During this process, the adhesive in the dispensing groove 170 is pressed tightly to form a strong adhesive force. After the dispensing is completed and the bracket 110 is installed, wait for the adhesive to cure. During the curing process, a long-lasting adhesive force is formed between the adhesive and the contact surfaces of 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 impact resistance and service life of the entire device, making it especially suitable for use in environments with frequent pressing and collisions. Through the design of the dispensing section 1171 and the dispensing groove 170, the need for other connection methods (such as screw fixing) is reduced, the production cost of the product is reduced, and the assembly process is simplified.

[0121] In some embodiments, the bracket 110 is fixed to the button hole 310 of the middle frame 300 via injection molding. Injection molding involves injecting plastic material into a mold and forming it within the mold, ultimately achieving a secure connection between the bracket 110 and the middle frame 300. Injection molding can efficiently and precisely manufacture components with complex shapes and accurate dimensions, offering high production efficiency and consistency. It allows for precise control of the size and shape of the bracket 110, ensuring a good fit between the bracket 110 and the button hole 310 of the middle frame 300, preventing the button 130 from malfunctioning due to dimensional errors. The connection between the bracket 110 and the middle frame 300 after injection molding is more stable and robust, effectively resisting external impacts and pressure, and preventing loosening or detachment under frequent pressing operations. Injection molding allows for the selection of various plastic materials to meet the strength, wear resistance, and waterproofing requirements of different electronic devices. For example, using high-strength plastics can enhance the compressive strength of the bracket 110, while using flexible materials can improve impact resistance and shock absorption. Injection molding is suitable for mass production, enabling the production of large quantities of bracket 110 and mid-frame 300 components of the same specifications in a short time, thereby improving production efficiency and reducing unit production costs.
