Therefore, a related elastic conductive structure is often used to complete the transition connection between the conductive contact of the switch piece and the circuit board, which causes the complication of the product structure and increases the processing and assembly costs.

DETAILED DESCRIPTION

[0032] To make the objectives, technical solutions, and superiorities of the embodiments of the present application clearer, the following will be a clear and complete description of the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0033] As shown in Figures 1-6 , the main structure of the electronic device provided by the embodiments of the present application includes a middle frame 300, a bottom shell 400, a first circuit board 500, a switch member 160, and a pressing assembly. The types of electronic devices include but are not limited to mobile phones, tablet computers, scanning pens, digital cameras, smart watches, etc. The present specification takes the smart watch type wearable electronic device as shown in Figure 1 , Figures 4-5 as an example for illustrative description.

[0034] In the electronic device, the middle frame 300 is provided with a key hole 310 penetrating the inner side and the outer side of the middle frame 300; the bottom shell 400 is fixed on one side of the thickness direction of the middle frame 300, and the bottom shell 400 is provided with a fixing seat 410 located on the inner side of the middle frame 300 and opposite to the key hole 310; the first circuit board 500 is arranged between the fixing seat 410 and the switch element 160; the switch element 160 is connected to the first circuit board 500; the pressing assembly is installed in the key hole 310 and is configured to trigger the switch element 160 by pressing the pressing assembly.

[0035] The middle frame 300 is an external frame structure of the electronic device, and the bottom shell 400 is connected with the middle frame 300 and closes the back of the electronic device. The middle frame 300 and the bottom shell 400 together bear various internal components of the electronic device and provide support and protection for internal circuits and elements. The key hole 310 penetrating the inner and outer sides is provided on the middle frame 300 for accommodating and fixing the pressing assembly. The shape and size of the key hole 310 are determined according to the design requirements of the pressing assembly to ensure that the pressing assembly can be smoothly installed and fixed and adapt to the pressing action.

[0036] The first circuit board 500 is arranged on the fixing seat 410, and the switch element 160 is connected to the first circuit board 500. The switch element 160 is a key element in the electronic device for receiving physical pressing and transmitting electrical signals to the first circuit board 500 after being pressed. Since the fixing seat 410 is integrated on the bottom shell 400 and directly connected with the first circuit board 500, the fixing of the switch element 160 becomes more convenient and firm.

[0037] The pressing assembly is installed in the key hole 310. When the user presses the pressing assembly, the switch element 160 is triggered by the partial mechanism action in the form of pressing. In this design, the first circuit board 500 is arranged between the fixing seat 410 and the switch element 160. The front side of the switch element 160 is directly pressed by the pressing assembly, and the back side of the switch element 160 is connected to the first circuit board as a connection contact. Since the first circuit board 500 is clamped between the fixing seat 410 and the back side of the switch element 160, the first circuit board 500 is extruded after the front side of the switch element 160 is pressed by the pressing assembly, thereby forming a more stable contact connection with the switch element 160. Compared with the connection of the connection contact on the side of the switch element and the circuit board, no related elastic conductive structure is needed for transition connection, which simplifies the product structure and reduces the processing and assembly cost.

[0038] In addition, in the related art, there is a related scheme of integrating the fixed seat and the switch piece on the pressing assembly, clamping the first circuit board between the back of the fixed seat and the switch piece, which can also achieve the effect of stable connection between the first circuit board and the switch piece when frequently pressed, but makes the structure of the pressing assembly too complex, limits the connection position and connection mode of the switch piece and the first circuit board to the specific structure of the pressing assembly, and causes adverse effects. In the present application, the fixed seat is arranged on the bottom shell, which can fully utilize the internal space of the electronic device and the laying requirement of the first circuit board in the electronic device, and reasonably arrange the position of the fixed seat, and will not make the structure of the pressing assembly too complex.

[0039] In some embodiments, the bottom shell 400 is integrally formed with the fixed seat 410, the fixed seat 410 is located inside the middle frame 300 and directly opposite the key hole 310. The fixed seat 410 is manufactured by integrally forming, which ensures the stability of the structure and reduces the number of components, avoiding the need for additional switch fixing supports in traditional designs. Therefore, this design simplifies the production process and reduces the processing and assembly costs.

[0040] In summary, the above-mentioned embodiments of the present application integrally form the fixed seat 410 on the bottom shell 400, and no longer need to design an independent fixing support to fix the switch piece 160. First, the overall structure of the electronic device is effectively simplified, the number of components is reduced, and the simplified structure design further reduces the required process and assembly steps in the production process, reducing production costs and assembly difficulty. Second, the integrally formed fixed seat 410 provides stable support and avoids the loosening or wear problems that may be caused by unstable assembly of the switch fixing support in traditional designs. It is particularly suitable for modern consumer electronic devices, especially smart watches and other products with high requirements for miniaturization and thinness.

[0041] Preferably, the switch piece 160 is attached to the first circuit board 500 through the SMT process. The SMT process is used to directly mount electronic components onto the surface of the circuit board, rather than connecting through the traditional pin insertion hole. The application of the SMT process can greatly improve production efficiency, reduce space occupation, and more accurately control the connection quality during the manufacturing process. By attaching the switch piece 160 to the first circuit board 500 through the SMT process, high-precision mounting can be achieved, reducing human error, and due to the use of automated equipment, the mounting efficiency is greatly improved. The switch piece 160 in the traditional process may need to be connected through the pin insertion into the circuit board or other connection methods, which will occupy more board space. Using the SMT process, the switch piece 160 is directly attached to the surface of the circuit board, not only improving the space utilization, but also making the overall design of the circuit board more compact, adapting to the increasingly small and thin electronic device requirements. The SMT process is automated and has high precision, and the attachment process is more stable and reliable. Through high-temperature welding (such as reflow soldering) in the process, it can ensure that the connection between the switch piece 160 and the first circuit board 500 is stable and durable. This firm connection can effectively reduce the problem of switch piece 160 falling off or poor contact during use, thereby improving the long-term stability of the product.

[0042] The steps of attaching the switch piece 160 to the first circuit board 500 through the SMT process can be referred to as follows: First, the switch piece 160 is pretreated to adapt to the SMT process, and the back contact surface of the switch piece 160 can be coated with a layer of solderable material to ensure the quality of the welding; then use the SMT equipment to accurately mount the switch piece 160 at the designated position of the first circuit board 500, the SMT equipment uses surface mounting technology to accurately position and weld the components, and the switch piece 160 will be directly attached to the surface of the first circuit board 500; then through the reflow soldering process, the pads of the switch piece 160 are connected to the pads on the first circuit board 500. During the reflow soldering process, the soldering material is heated and melted to form a reliable electrical connection; finally, after the mounting and welding are completed, visual inspection and electrical testing are performed to ensure that the connection between the switch piece 160 and the first circuit board 500 is good and there is no welding defect or poor contact phenomenon.

[0043] In some embodiments, the first circuit board 500 is a flexible circuit board. The flexible circuit board has good flexibility and bendability, and is suitable for electronic devices that require higher integration and compact design. However, due to the thinness and flexibility of the flexible circuit board, it may have certain bending deformation when subjected to external stress and physical pressure, thereby affecting the stability and reliability of the circuit. In order to overcome this problem and further optimize the stability and durability of the product, such as Figure 2 and 6As shown, the present embodiment provides a reinforcing design, i.e. a reinforcing plate 600 is arranged between the first circuit board 500 and the fixing seat 410.

[0044] The reinforcing plate 600 is usually made of a material with high rigidity, such as metal or hard plastic, and has sufficient rigidity and strength to avoid affecting the electrical performance of the flexible circuit board or causing damage due to pressure or bending deformation during long-term use. The design of the reinforcing plate 600 can be customized according to the specific shape, size of the first circuit board 500 and the requirements of the installation space. The reinforcing plate 600 is installed with the first circuit board 500 by a close-fitting manner, so that a support structure is formed between the reinforcing plate 600 and the flexible circuit board, ensuring that the flexible circuit board remains flat under external force and reducing the phenomenon of poor contact or breakage caused by bending or pressure. The reinforcing plate 600 effectively enhances the rigidity of the flexible circuit board, prevents it from being damaged or poorly connected due to bending or external force during use, and improves the reliability of the first circuit board 500.

[0045] In some embodiments, as shown in Figure 2 and 6 The fixing seat 410 includes a first vertical plate 411 and a second vertical plate 412 connected vertically, the first vertical plate 411 is arranged opposite to the key hole 310, the surface of the reinforcing plate 600 away from the pressing assembly is connected with the first vertical plate 411, and one side of the reinforcing plate 600 and the first circuit board 500 abuts against the second vertical plate 412.

[0046] Specifically, the first vertical plate 411 is arranged opposite to the key hole 310, which is to provide a stable support surface for the pressing assembly. The position and shape of the key hole 310 are accurately designed to ensure that the pressing assembly can accurately dock with the switch piece 160 and trigger the corresponding signal after assembly. The close connection of the reinforcing plate 600 and the first vertical plate 411 is the key to achieving structural stability. One side of the reinforcing plate 600 is connected with the first vertical plate 411, and the other side of the reinforcing plate 600 is closely fitted with the first circuit board 500. In this way, the reinforcing plate 600 is supported by the first vertical plate 411, avoiding possible deformation or stress concentration of the flexible circuit board during use. This combination not only increases the mechanical strength of the first circuit board 500, but also prevents poor contact caused by long-term pressing or vibration.

[0047] In the working process of the pressing assembly, when the user presses the pressing assembly, the pressing force generated is directly applied to the switch piece 160 through the pressing assembly, and then transmitted to the first vertical plate 411 through the first circuit board 500 and the reinforcing plate 600. The first vertical plate 411 becomes the final pressure bearing structure and bears all the pressure from the pressing assembly. Therefore, the first vertical plate 411 must have sufficient strength and rigidity to ensure that it will not deform or be damaged during the pressing process. The second vertical plate 412 is connected perpendicularly to the first vertical plate 411. This perpendicular connection design greatly enhances the mechanical stability of the first vertical plate 411 when bearing the pressing force. Specifically, the bottom shell 400, the first vertical plate 411, and the second vertical plate 412 form a spatially stable three-dimensional structure through the orthogonal structure of each other. This structure can effectively withstand the impact force from the pressing assembly, thereby improving the overall load capacity.

[0048] Another function of the second vertical 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 vertical plate 412. The position of the reinforcing plate 600 and the first circuit board 500 in the direction perpendicular to the second vertical plate 412 is positioned by the second vertical plate 412. Through the perpendicular connection of the first vertical plate 411 and the second vertical plate 412, the entire fixing seat 410 can position the reinforcing plate 600 and the first circuit board 500 in the direction perpendicular to the first vertical plate 411 and the direction perpendicular to the second vertical plate 412. This improves the assembly efficiency of the component, makes the assembly more accurate, greatly simplifies the traditional complex assembly process, and improves the production efficiency.

[0049] In some embodiments, as shown in Figures 2-3 、 Figures 6-9 and Figures 11-13 , the pressing assembly in the electronic device includes a bracket 110 and a key 130. The bracket 110 has a first shaft hole 111 passing through it. The key 130 can move along the axial direction of the first shaft hole 111 and trigger the switch piece 160. The bracket 110 is embedded in the key hole 310 and fixedly connected with the middle frame 300. The bracket 110 is fixed with the middle frame 300, which improves the connection stability and sealing effect.

[0050] The first shaft hole 111 formed on the support 110 allows the key 130 to move freely in the axial direction, which enables the key 130 to accurately trigger the internal switch piece 160 when pressed by external force. The support 110 is embedded in the key hole 310 and fixedly connected with the middle frame 300, and the middle frame 300 serves as the main supporting structure of the electronic device, and the fixed connection with the support 110 ensures the stability of the pressing assembly. During the operation of the key 130, the support 110 acts as a bearing structure and can effectively disperse the pressure received by the key 130 to the middle frame 300.

[0051] Since the support 110 is fixedly connected with the middle frame 300, the sealing effect of the connection is enhanced, and external dust, moisture, etc. is prevented from entering the interior of the electronic device through the gap between the support 110 and the middle frame 300, which helps to improve the protection capability of the electronic device, especially in terms of water resistance and dust resistance, ensuring that the device can work stably under different environmental conditions and improving the durability and reliability of the entire electronic device.

[0052] In some embodiments, the support 110 is fixedly adhered in the key hole 310 of the middle frame 300 by a dispensing process. The dispensing process forms a firm connection between the support 110 and the middle frame 300 by applying glue at the interface where the support 110 contacts the middle frame 300. The dispensing process is simple to operate and efficient, and can ensure the sealing and stability between the support 110 and the middle frame 300. In addition, the selection of glue can be adjusted according to the specific needs of the electronic device to ensure that it does not age or fall off easily during long-term use.

[0053] The dispensing process does not require complex mechanical connections or additional fixing parts, and can achieve stable connection in a short time, reducing labor costs and assembly cycle in the production process. By dispensing, a thin and uniform sealing glue layer can be formed on the contact surface between the support 110 and the key hole 310, further enhancing the waterproof and dustproof capability of the electronic device, especially when used in harsh environments, which can prevent dust and moisture from entering the interior of the device. The dispensing process can provide sufficient adhesive force to ensure firm fixation between the support 110 and the middle frame 300, avoiding loosening or displacement during use, and improving the stability and reliability of the device. The glue will be evenly distributed on the contact surface between the support 110 and the middle frame 300 when dispensing, which helps to disperse the pressure generated during the operation of the key 130, reduces local stress concentration, and thus improves the service life of the key 130.

[0054] In some embodiments, as Figure 3 , Figure 7 , Figures 11-12As shown, the keyhole 310 includes a first hole section 311 close to the inner side and a second hole section 312 close to the outer side, the cross section of the first hole section 311 is smaller than that of the second hole section 312, and a first stop surface 313 towards the outer side is formed between the first hole section 311 and the second hole section 312; the bracket 110 includes a first bracket section 116 matched with the first hole section 311 and a second bracket section 117 matched with the second hole section 312, and a second stop surface 118 towards the first stop surface 313 is formed between the first bracket section 116 and the second bracket section 117, in the state that the bracket 110 is matched and embedded in the keyhole 310, the first stop surface 313 and the second stop surface 118 are in abutting cooperation.

[0055] When the first bracket section 116 and the second bracket section 117 of the bracket 110 are accurately matched with the first hole section 311 and the second hole section 312 of the keyhole 310 respectively, the first stop surface 313 and the second stop surface 118 cooperate with each other, thereby ensuring the close connection between the bracket 110 and the middle frame 300, effectively avoiding the problems of looseness or misalignment in the assembly process, and improving the connection stability. The cooperation 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 keyhole 310, without the need for additional fixing parts or complex assembly operations. In this way, the installation of the bracket 110 is more convenient, and errors or position deviations that may occur in the traditional installation method are avoided, compared with the traditional manual positioning and alignment process, the overall assembly efficiency is improved. Through the surface contact cooperation of the first stop surface 313 and the second stop surface 118, the impact force in the pressing process of the key 130 is effectively dispersed, the looseness or deformation of the bracket 110 caused by force concentration is reduced, and the durability and stability of the overall structure are enhanced.

[0056] In the actual assembly process, first, one end of the first bracket section 116 of the bracket 110 is inserted from the outer side of the keyhole 310. When the bracket 110 is completely inserted into the keyhole 310, the first stop surface 313 and the second stop surface 118 abut each other, at this time, the accurate positioning between the bracket 110 and the middle frame 300 is completed. In this process, the stop surface helps the bracket 110 to be stably positioned in the middle frame 300 through contact and cooperation, avoiding possible position deviation or looseness in the assembly process, and ensuring the firm connection between the bracket 110 and the keyhole 310.

[0057] On the basis of the above-mentioned embodiments, the second support section 117 connects the outer contour of one end of the first support section 116 to form a dispensing section 1171. In the state that the support 110 is matched and embedded in the keyhole 310, the dispensing section 1171, the first stop surface 313 and the inner wall of the second hole section 312 form a dispensing groove 170. By designing the dispensing section 1171 to cooperate with the support 110 to form the dispensing groove 170, the dispensing material can be effectively accommodated, so that the dispensing process can more accurately and uniformly distribute glue on the area where the support 110 contacts the keyhole 310. The dispensing section 1171 and the dispensing groove 170 effectively enhance the bonding firmness between the support 110 and the middle frame 300, avoiding loosening or separation caused by uneven dispensing or poor bonding. In traditional assembly, dispensing process requires additional tools or complex operation. By designing the dispensing section 1171 on the support 110 and forming the dispensing groove 170, the dispensing process can be more automated and simple. The operator only needs to preposition the dispensing material in the dispensing section 1171, without the need for accurate alignment and manual application, thereby improving the assembly efficiency. The glue bonding provided by the dispensing section 1171 and the dispensing groove 170 not only enhances the connection strength between the support 110 and the middle frame 300, but also effectively absorbs the impact force generated in the pressing process, reduces local damage caused by force concentration, and improves the impact resistance of the product during use.

[0058] The specific assembly process can be exemplarily listed as follows: first, apply an appropriate amount of dispensing material to the dispensing section 1171 area of the support 110; then insert the dispensing support 110 into the keyhole 310, at this time, the dispensing section 1171 of the support 110 forms a dispensing groove 170 with the inner wall of the second hole section 312 and the first stop surface 313 in the keyhole 310, and the glue in the dispensing groove 170 is pressed tightly to form a firm bonding force; after the dispensing is completed and the support 110 is installed, wait for the glue to solidify, during the solidification process, the glue forms a long-term bonding force between the contact surface of the support 110 and the keyhole 310, effectively enhancing the bonding strength of the support 110 and the middle frame 300, thereby improving the impact resistance and service life of the entire device, especially suitable for use in environments with frequent pressing and collision. 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.

[0059] In some embodiments, the support 110 is fixed in the keyhole 310 of the middle frame 300 by an injection molding process. The injection molding process injects plastic material into a mold and shapes it in the mold to finally achieve firm combination between the support 110 and the middle frame 300. The injection molding process can efficiently and accurately manufacture components with complex shapes and precise dimensions, with high production efficiency and consistency.

[0060] The injection molding process can precisely control the size and shape of the bracket 110, ensuring good cooperation between the bracket 110 and the keyhole 310 of the middle frame 300, and avoiding the size error that causes the key 130 to be unable to be normally used. The connection between the bracket 110 and the middle frame 300 after the injection molding process is more stable and firm, which can effectively resist external impact and pressure, and avoid the connection loosening or falling off phenomenon under frequent pressing operation. The injection molding process can select different types of plastic materials to meet the needs of different electronic devices for strength, wear resistance and waterproof performance, for example, using high-strength plastic can enhance the pressure resistance of the bracket 110, and using flexible material can improve the impact resistance and shock absorption capacity. The injection molding process is suitable for mass production, which can produce a large number of bracket 110 and middle frame 300 assemblies of the same specification in a short time, thereby improving production efficiency and reducing unit production cost.

[0061] In some embodiments, as shown in Figure 2 , Figures 8-9 and Figures 12-13 , the key 130 includes a key cap 132 and a key shaft 131, the key shaft 131 penetrates the first shaft hole 111 and can move along the axial direction of the first shaft hole 111, the key shaft 131 is provided with a groove 1316 in the circumferential direction, and the sealing ring 133 is sleeved on the groove 1316, and the sealing ring 133 is in sealing connection with the inner wall of the first shaft hole 111. In this embodiment, the sealing ring 133 is in sealing connection with the inner wall of the first shaft hole 111, preventing external liquid or dust from entering the interior of the assembly, protecting the internal electronic components from pollution and damage, improving the protection level of the assembly, and being suitable for application scenarios requiring waterproof and dustproof. The presence of the sealing ring 133 enhances the connection stability between the key shaft 131 and the first shaft hole 111, reduces loosening or displacement caused by friction or vibration, and ensures the long-term reliability of the assembly. By providing the groove 1316 on the key shaft 131 and sleeving the sealing ring 133, the design of the sealing structure is simplified, and the complexity of production and assembly is reduced.

[0062] The main structure of the pressing assembly in the electronic device provided by the embodiments of the present application further includes a conductive sheet 120, a reset member 140 and an auxiliary conductive structure 150. The pressing assembly is a dual-purpose key that can realize touch and pressing functions, which can be used as a pressing assembly of various electronic devices.

[0063] As shown in Figure 2 , Figure 3 , Figures 6-13The conductive sheet 120 is fixed on the second side of the bracket 110, and a second shaft hole 121 is formed in the conductive sheet 120 and faces the first shaft hole 111. The key 130 includes a key shaft 131 penetrating the first shaft hole 111 and the second shaft hole 121, and the key 130 is movable along the axial direction of the first shaft hole 111. The key shaft 131 includes a first shaft section 1311 located on the side of the conductive sheet 120 away from the bracket 110, and the first shaft section 1311 forms a first abutting surface 1314 on the side facing the conductive sheet 120. The reset member 140 is configured to make the first abutting surface 1314 always have a tendency to move towards the conductive sheet 120 along the axial direction of the first shaft hole 111. When the first abutting surface 1314 is out of contact with the conductive sheet 120, the key 130 is electrically connected to the conductive sheet 120 through the auxiliary conductive structure 150.

[0064] In the above embodiment, the bracket serves as a main bearing structure for bearing the key 130, the reset member 140, and the conductive sheet 120. When the key 130 is touched, the first abutting surface 1314 of the key 130 and the conductive sheet 120 form a first conduction path. The key 130 is used for conducting an electrical signal after being touched, and is moved along the first shaft hole 111 after being pressed to trigger related elements as a traditional physical key. The conductive sheet 120 is used for directly or indirectly connecting with the circuit system of the electronic device to transmit the touch electrical signal under the touch function to the circuit system, for example, the conductive sheet 120 can be electrically connected with a second circuit board 200 in the circuit system. Due to the presence of the reset member 140, the first abutting surface 1314 is in abutment with the conductive sheet 120 when the key 130 is not pressed by external force and is in a natural state.

[0065] The physical pressing trigger device of the pressing assembly is a switch 160, which is arranged on the side of the first shaft section 1311 away from the key cap 132. When the key 130 is pressed, the first shaft section 1311 moves towards the switch 160 and triggers the switch 160. The key 130 is used for moving along the first shaft hole 111 after being pressed to trigger the switch 160 as a traditional physical key. The switch 160 is used for directly or indirectly connecting with the circuit system of the electronic device to transmit an electrical signal to the circuit system.

[0066] When the touch conduction function is needed to be used, the user touches the outer surface of the key 130 with a finger, the key 130 does not displace, the first abutting surface 1314 and the conductive sheet 120 still remain in the abutting state, at this time, the human body, the first abutting surface 1314 of the key 130 and the conductive sheet 120 form a first conduction path to transmit the touch electric signal to the circuit system of the electronic device; when the pressing function is needed to be used, the user applies a pressing force on the outer surface of the key 130 with a finger, the key 130 will displace along the first shaft hole 111 against the resetting force of the resetting member 140, the displacement direction is from the first side to the second side, so as to trigger the corresponding controlled element through the key 130 after movement, and the pressing trigger function is realized, in this process, the first abutting surface 1314 and the conductive sheet 120 will be out of contact, so that the first conduction path cannot be realized in the pressing process, in order for the key 130 to realize the touch conduction function while realizing the pressing trigger function, in the embodiment, when the first abutting surface 1314 and the conductive sheet 120 are out of contact, the key 130 is electrically connected with the conductive sheet 120 through the auxiliary conductive structure 150, that is, the human body, the key 130, the auxiliary conductive structure 150 and the conductive sheet 120 form a second conduction path to transmit the touch electric signal to the circuit system of the electronic device; when the user no longer presses the key 130, the key 130 will reset to the natural state under the action of the resetting member 140, and the first abutting surface 1314 and the conductive sheet 120 are in abutment again.

[0067] In the above working process, in the natural state and the touch state, the first abutting surface 1314 of the key 130 and the conductive sheet 120 remain in the abutting state, and the conductive sheet 120 is clamped between the first shaft section 1311 and the support 110, the abutting force is provided by the resetting member 140, without the need for the conductive sheet 120 to be elastically deformed to provide the abutting force, in the pressing state, the movement of the key 130 will not cause the deformation of the conductive sheet 120, but the first abutting surface 1314 of the key 130 and the conductive sheet 120 will be out of contact. In this technical solution, whether in the touch use scene or in the pressing use scene, the conductive sheet 120 will not move and deform, and will not cause fatigue accumulation of the conductive sheet 120, thereby improving the working life. In addition, in the above embodiment, the abutting state between the first abutting surface 1314 and the conductive sheet 120 can prevent the key shaft 131 of the key 130 from being pulled out of the first shaft hole 111, without the need for additional setting of other anti-pulling-out limiting structures.

[0068] In summary, the pressing assembly provided in the embodiment has at least the following four key design advantages.

[0069] First, the conductive sheet 120 has zero deformation. In the natural state, the touch state and the pressing process, the conductive sheet 120 only serves as a static contact surface or a non-contact structure, without the need for elastic deformation, thereby greatly eliminating the risk of fatigue failure.

[0070] Second, dual touch signal path protection. The key 130 in the touch state is directly connected with the conductive sheet 120 through the first abutting surface 1314, and the key 130 in the pressing state is connected with the conductive sheet 120 through the auxiliary conductive structure 150, which ensures the stable work of the touch function in the whole operation cycle.

[0071] Third, self-limiting structure simplification. The elastic force of the reset member 140 makes the abutting cooperation of the first abutting surface 1314 and the conductive sheet 120, which realizes the axial limiting of the key 130 to prevent the key 130 from falling out, without the need for additional limiting components such as buckles or screws, thereby reducing the assembly complexity.

[0072] Fourth, the reset member 140 independently bears mechanical stress, and the conductive sheet 120 only transmits touch electrical signals, and the functions of the two are separated and each performs its own function, which significantly improves the overall reliability and service life of the assembly.

[0073] It should be noted that in the above embodiments, the conductive sheet 120 and the key 130 are both conductors, and the bracket 110 is an insulator.

[0074] In some embodiments, the key 130 of the pressing assembly further comprises a key cap 132, which is located on the side of the first shaft hole 111 away from the conductive sheet 120. Figure 2 Figures 6-8 As shown, the auxiliary conductive structure 150 comprises a first spring 151 and a conductive column 152, the first end of the first spring 151 is connected to the side of the key cap 132 facing the bracket 110, and the conductive column 152 is connected to the conductive sheet 120 and extends into the bracket 110; when the first abutting surface 1314 is separated from the conductive sheet 120, the second end of the first spring 151 abuts against the conductive column 152. The key cap 132 is used as the operating end of the key 130 and can be touched and pressed by the user. At least part of the key cap 132 is exposed outside the bracket 110 to be touched or pressed by the user. The key cap 132 of the key 130 is a structure suitable for finger touch and pressing, and the surface thereof can be provided with anti-slip texture and appropriate surface area according to needs to adapt to finger touch and pressing. The key cap 132 is arranged on the first side of the bracket 110, and the key cap 132 itself protrudes radially from the key shaft 131. During the movement of the key shaft 131 along the first shaft hole 111 towards the switch member 160, the key cap 132 is blocked and cannot move after abutting against the bracket 110, and the key cap 132 can play a limiting role in the limit position.

[0075] ​The above embodiments give a specific implementation of the auxiliary conductive structure 150, that is, the auxiliary conductive structure 150 includes the first spring 151 and the conductive column 152. In the pressing process of the key 130, the first spring 151 can be in contact with the conductive column 152 to form a second conduction path composed of the keycap 132, the first spring 151, the conductive column 152, and the conductive sheet 120, thereby transmitting the touch electrical signal to the circuit system of the electronic device. When the key 130 is released, the elastic force of the reset member 140 restores the key 130 to the natural state, ensuring that the first abutting surface 1314 recontacts the conductive sheet 120.

[0076] In this embodiment, first, the auxiliary conductive structure 150 selects the cooperation mode of the first spring 151 and the conductive column 152, and the key 130 in the natural state, the touch state, and the movement process will not cause the deformation of the conductive sheet 120, ensuring that the fatigue failure risk of the conductive sheet 120 is eliminated, and the working life is improved. Second, the cooperation of the first spring 151 and the conductive column 152 of the auxiliary conductive structure 150 in this embodiment can participate in forming the second conduction path, ensuring that the transmission of the touch signal in the pressed state is realized, and ensuring the stable work of the touch function in the pressed state. Third, due to the deformable property of the first spring 151, the pressing process of the key 130 can continue after the first spring 151 abuts against the conductive column 152, and the auxiliary conductive structure 150 will not prevent the pressing displacement of the key 130, ensuring that the displacement of the key 130 can trigger the corresponding element. In addition, the auxiliary conductive structure 150 selects the design structure of the first spring 151 and the conductive column 152, which is simple, simplifies the structure of the touch and press dual-purpose key, improves the reliability, and reduces the production cost.

[0077] On the basis of the above embodiment, the bracket 110 is provided with a first mounting groove 112 on the side facing the keycap 132, and a second mounting groove 113 on the side facing the conductive sheet 120. The first mounting groove 112 and the second mounting groove 113 are in communication, the first spring 151 extends into the first mounting groove 112, and the conductive column 152 extends into the second mounting groove 113.

[0078] By this design, the first spring 151 and the conductive column 152 are fixed in two different directions of the bracket 110 respectively, so that they can stably cooperate with other components and ensure the stability of the pressing assembly during the pressing of the key 130. Specifically, the design of the first mounting slot 112 and the second mounting slot 113 allows the first spring 151 and the conductive column 152 to maintain their correct positions when the key 130 is pressed, avoiding their positional deviation or unnecessary deformation. The first mounting slot 112 is in communication with the second mounting slot 113 for ensuring that the first spring 151 and the conductive column 152 can achieve physical contact connection, and through the conductive column 152 and the conductive sheet 120, a second conduction path is formed to transmit the touch electrical signal to the circuit system of the electronic device.

[0079] In some embodiments, as shown in Figure 8 and 10 The conductive sheet 120 is provided with a first through hole 122 opposite to the second mounting slot 113, and the conductive column 152 is screwed with the second mounting slot 113 after penetrating the first through hole 122 to fix the conductive sheet 120 to the bracket 110. The conductive column 152 not only participates in the signal transmission of the second conduction path, but also serves as a fixing member to firmly fix the conductive sheet 120 to the bracket 110. The conductive column 152 is screwed with the second mounting slot 113 to ensure the stability of signal transmission and the mechanical connection between the conductive sheet 120 and the bracket 110, thereby enhancing the structural stability of the assembly.

[0080] When the key 130 is in the pressed state, the conductive column 152 is in contact with the second end of the first spring 151 to participate in the formation of the second conduction path and continue to transmit the touch signal to the circuit system. Since the conductive column 152 plays a role in the fixed installation of the conductive sheet 120, its design ensures the stability of the structure and avoids the loosening or displacement of the conductive sheet 120 during long-term use. That is, the conductive column 152 not only solves the problem of the conductive path, but also considers the fixation of the conductive sheet 120, simplifies the structural design, improves the reliability, and reduces the need for additional fixing members.

[0081] The first shaft segment 1311 is located at one end of the key shaft 131 away from the key cap 132, and a first abutting surface 1314 is machined on the surface of the first shaft segment 1311 towards the conductive sheet 120, and a third abutting surface 1317 is machined on the surface of the first shaft segment 1311 away from the conductive sheet 120. Due to the presence of the reset member 140, when the key 130 is not pressed by external force and is in a natural state, the first abutting surface 1314 abuts against the conductive sheet 120; when the user presses the key cap 132 to move the key 130 towards the switch member 160 against the reset force of the reset member 140, the third abutting surface 1317 gradually approaches and abuts against the switch member 160 to trigger the switch member 160. After the user releases the pressed key 130, the reset member 140 drives the key shaft 131 to move along the axial direction of the first shaft hole 111, so that the first abutting surface 1314 contacts the conductive sheet 120, the key 130 is reset, and the conductive sheet 120 plays a limiting role in another extreme position, so that the key shaft 131 cannot be separated from the bracket 110.

[0082] On the one hand, the reset force of the reset member 140 in the above embodiment makes the first abutting surface 1314 abut against the conductive sheet 120, which realizes the axial limiting of the key 130 to prevent the key 130 from being separated out, without the need for additional limiting components such as buckles or screws, simplifying the product structure and reducing the assembly complexity; on the other hand, the conductive sheet 120 is a fixed structure, and the first shaft segment 1311 is a structure of the key shaft 131 itself, compared with the limiting by sleeving a spring sheet on the key shaft 131, the contact limiting between the first shaft segment 1311 and the conductive sheet 120 can improve the stability in the limiting state and reduce the risk of part falling off. Preferably, the conductive sheet 120 is preferably a plate structure, and a plane parallel to the first abutting surface 1314 is formed on the side of the conductive sheet 120 towards the first shaft segment 1311, so that the first shaft segment 1311 and the conductive sheet 120 are in surface contact when they abut against each other, further improving the stability in the limiting state.

[0083] As the first spring 151 and the first form of cooperation of the conductive column 152, in some embodiments, the end of the conductive column 152 extends into the first mounting groove 112, and the second end of the first spring 151 is arranged separately from the conductive column 152 when the first abutting surface 1314 is in contact with the conductive sheet 120. In this way, in the non-pressed state (including the natural state and the touch state), only the first conduction path works, and the second conduction path is not activated due to the disconnection of the first spring 151 and the conductive column 152. Specifically, when the key 130 is in the natural state or the touch state, the first conduction path is in contact with the conductive sheet 120 through the first abutting surface 1314 to transmit the touch signal to the circuit system of the electronic device. At this time, the second conduction path is in a non-working state because the second end of the first spring 151 is not in contact with the conductive column 152, so that an effective circuit connection cannot be formed. When the user presses the key 130, the first abutting surface 1314 is separated from the conductive sheet 120, and the first conduction path is interrupted, at which time the second end of the first spring 151 gradually approaches the conductive column 152 and eventually realizes the contact cooperation with the conductive column 152, thereby forming the second conduction path. At this time, the second conduction path is activated and continues to work, ensuring that the touch signal can still be transmitted in the pressed state.

[0084] The design can selectively activate the first conduction path or the second conduction path through the switching of the first conduction path and the second conduction path, ensuring the stability and flexibility of the touch signal transmission in the pressed and non-pressed states. In the non-pressed state, only the first conduction path works, and the second conduction path does not work, effectively avoiding unnecessary signal transmission interference and maintaining the purity of the touch signal. Through the ingenious design of the conductive column 152 and the first mounting groove 112, the smooth working of the key 130 in different states is ensured, and the reliability of the overall structure is improved.

[0085] The embodiment can be applied to the following working scenarios by only having the first conduction path work in the non-pressed state, and when the pressed state is started, the first conduction path is interrupted, and the second conduction path continues to work through the contact of the first spring 151 and the conductive column 152.

[0086] Scenario a: applicable to devices that need to switch the operation function mode. For example, in a smart watch or a sports bracelet, the touch signal (first conduction path) in the touch state is used for basic first function operation, and the touch signal (second conduction path) in the pressed state is used to trigger second different function operation, such as activating the setting interface or starting the special function. At this time, the transmission of the touch signal of the first conduction path is disconnected when the pressing starts, and the second conduction path has not been activated, which can effectively avoid the false touch and unnecessary operation, and realize the switching of the two touch functions.

[0087] Scenario b: suitable for low-power devices, such as some portable sound, simple remote control, etc. In the non-pressing state, the touch signal is transmitted through the first conduction path, and the touch signal in the pressing state is transmitted through the second conduction path. In the implementation of the two states, the touch information can be transmitted without consuming too much power.

[0088] Scenario c: suitable for electronic devices with extremely high signal interference requirements. If the first conduction path and the second conduction path are in working state at the same time, the signal transmission between them may be out of sync. In the non-pressing state, the second conduction path does not work, effectively avoiding unnecessary signal transmission interference and maintaining the purity of the touch signal.

[0089] As a second form of cooperation between the first spring 151 and the conductive column 152, in some embodiments, the end of the conductive column 152 of the pressing assembly extends into the first mounting groove 112, and the second end of the first spring 151 abuts the conductive column 152 when the first abutting surface 1314 contacts the conductive sheet 120. In this embodiment, in the non-pressing state (including the natural state and the touch state), the first conduction path and the second conduction path are in the activated state. Specifically, when the key 130 is in the natural state or the touch state, the first conduction path contacts the conductive sheet 120 through the first abutting surface 1314, and transmits the touch signal to the circuit system of the electronic device. At this time, the second conduction path abuts the conductive column 152 through the second end of the first spring 151, transmits the touch signal to the circuit system of the electronic device, and forms an effective circuit connection. When the user presses the key 130, the first abutting surface 1314 is separated from the conductive sheet 120, and the first conduction path is interrupted. At this time, the second end of the first spring 151 can abut on the conductive column 152 more stably after being compressed and deformed, and the second conduction path continues to work, ensuring that the touch signal can still be transmitted in the pressing state.

[0090] This design makes the first conduction path and the second conduction path work in the non-pressing state, and the key 130 and the conductive sheet 120 are always in communication after the pressing action is started. The second conduction path is always in working state, and the component does not have a touch signal transmission breakpoint in the switching process of touch and pressing action.

[0091] The first conduction path and the second conduction path both work in the non-pressing state, and when the pressing action is started, the first conduction path is interrupted, and the second conduction path continues to work, ensuring that the key 130 and the conductive sheet 120 are always connected. Especially suitable for scenarios that require stable and continuous touch signal transmission, especially for devices that frequently switch operation modes, to ensure that touch signals can operate stably in high-frequency pressing interactions, so that the device can process pressing actions without stopping touch signal transmission. Specific use scenarios are as follows.

[0092] Scenario d: When the smart watch is used for medical monitoring function, the touch signal is used to monitor the body health parameter, and the pressing operation is used to physically trigger other functions, such as display screen operation or menu selection, etc. In the process of pressing, it is necessary to maintain the continuous transmission of the touch signal to continuously monitor the body health parameter. By using the present embodiment, the touch signal and the pressing signal work in parallel, which can ensure that the transmission of the touch signal will not be interrupted during pressing.

[0093] Scenario e: When applied to a game control device (such as a handle), fast and frequent touch and pressing action switching is required, which can ensure the continuous transmission of the touch signal during switching and will not interrupt the game operation corresponding to the touch signal, providing efficient operation experience.

[0094] It should be noted that the applicability of the above two specific cooperation forms of the first spring 151 and the conductive column 152 depends on the use scenario and the specific operation mode requirements of the electronic device. Those skilled in the art can make adaptive adjustments and selections as needed.

[0095] In some use scenarios, the key 130 of the pressing assembly is pressed only to achieve physical triggering function and does not need to realize the transmission of the touch signal. In order to make a set of component structures compatible with this use scenario, the technical personnel further make the following improvements: the conductive column 152 is screw-connected with the first through hole 122 and / or the second mounting groove 113, and in the process of rotating the conductive column 152, the end of the conductive column 152 has a state of being located in the first mounting groove 112 and a state of being located in the second mounting groove 113.

[0096] In the embodiment, by rotating the conductive column 152, the technician can adjust the position of the end thereof as needed. The conductive column 152 can be screwed so that the end thereof is flexibly located in the first mounting groove 112 or the second mounting groove 113. This design enables the conductive column 152 to selectively activate the second conduction path in the pressed state of the key 130. Specifically, when the end of the conductive column 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 conductive column 152, so that the second conduction path is not activated, and only the physical operation of the key 130 is triggered when pressed. Conversely, when the end of the conductive column 152 is rotated into the first mounting groove 112, the end of the first spring 151 located in the first mounting groove 112 can be abutted and matched with the conductive column 152, the second conduction path can be activated, and when pressed, not only the physical triggering function of the key 130 is realized, but also the touch signal is transmitted through the second conduction path, and the touch conduction function is continued. By rotating the conductive column 152, the working mode of the pressing assembly can be flexibly selected according to actual needs, allowing different functional requirements to be realized in the same assembly, which can simplify the design, reduce unnecessary functions, or enhance the functions according to the needs, so that the device is compatible with different use scenarios, enhances the adaptability and customizability of the pressing assembly, and this design uses screw rotation adjustment without additional complex switches or adjustment mechanisms, saving design and installation space while maintaining the stability of the key 130 function. The use scenarios and needs of the device are constantly changing, and the technician can adjust the position of the conductive column 152 according to the specific use scenario of the device for flexible configuration, so that the assembly can be widely applied to different products.

[0097] The implementation of the rotation function of the conductive column 152 can be achieved by screwing only with the first through hole 122, by screwing only with the second mounting groove 113, or by screwing with the first through hole 122 and the second mounting groove 113 at the same time. The last one is preferred, in which the conductive column 152 is screwed with the first through hole 122 and the second mounting groove 113, and on the basis of realizing the foregoing technical effects, it can also realize the technical effect of fixing the conductive sheet 120 on the bracket 110.

[0098] In some embodiments, as Figure 9As shown, the key shaft 131 of the pressing assembly includes a first shaft segment 1311, a second shaft segment 1312 and a third shaft segment 1313, which are sequentially arranged, the second shaft hole 121 is sleeved on the second shaft segment 1312, the first shaft segment 1311 protrudes radially from the second shaft segment 1312 to form a first abutting surface 1314 towards one end of the conductive sheet 120, and the third shaft segment 1313 protrudes radially from the second shaft segment 1312 to form a second abutting surface 1315 towards one end of the conductive sheet 120. In this embodiment, the key shaft 131 of the pressing assembly is sequentially arranged by the first shaft segment 1311, the second shaft segment 1312 and the third shaft segment 1313 to form a multi-segment structure. In the natural state or when a user touches the key 130, the first abutting surface 1314 is in contact with the conductive sheet 120 to participate in forming a first conduction path to transmit the touch signal to the circuit system of the electronic device. At this time, the second conduction path is not activated. When the user presses the key 130, the first abutting surface 1314 is separated from the conductive sheet 120, the first conduction path is interrupted, and the second abutting surface 1315 gradually approaches and contacts the side of the conductive sheet 120 towards the bracket 110, thereby forming a second conduction path composed of the key 130, the second abutting surface 1315 of the key 130 and the conductive sheet 120, and continuing to transmit the touch signal to the circuit system, ensuring the transmission of the touch signal in the pressed state, that is, the second abutting surface 1315 plays the role of the auxiliary conductive structure 150 at this time.

[0099] It can be found that in the above embodiment, the second abutting surface 1315 is a limiting surface of the limit position of the key 130 in the pressed state, that is, when the second abutting surface 1315 abuts against the conductive sheet 120, the key 130 is blocked by the conductive sheet 120 and cannot continue to move, at this time, the activation of the second conduction path can only be realized when the key 130 moves to the limit position, the condition is too harsh, which limits the applicability of the pressing assembly. Based on this, as shown, Figure 12 on the basis of the above embodiment, the auxiliary conductive structure 150 includes a second spring 153 sleeved on the second shaft segment 1312, a first end of the second spring 153 is connected with the second abutting surface 1315, and a second end of the second spring 153 can abut against the side of the conductive sheet 120 towards the key cap 132 after the first abutting surface 1314 is separated from the conductive sheet 120.

[0100] The above embodiments give another specific implementation of the auxiliary conductive structure 150, that is, the auxiliary conductive structure 150 includes the second spring 153. In the pressing process of the key 130, the second spring 153 can be in contact with the conductive sheet 120 to form a second conduction path composed of the keycap 132, the second abutting surface 1315, the second spring 153, and the conductive sheet 120, thereby transmitting the touch electrical signal to the circuit system of the electronic device. When the key 130 is released, the elastic force of the reset member 140 can restore the key 130 to the natural state, ensuring that the first abutting surface 1314 recontacts the conductive sheet 120.

[0101] In this embodiment, first, the auxiliary conductive structure 150 selects the second spring 153 to cooperate with the conductive sheet 120, and the key 130 in the natural state, the touch state, and the movement process will not cause the deformation of the conductive sheet 120, ensuring that the fatigue failure risk of the conductive sheet 120 is eliminated, and the working life is improved. Second, the cooperation of the second spring 153 of the auxiliary conductive structure 150 and the conductive sheet 120 in this embodiment can participate in forming the second conduction path, ensuring that the transmission of the touch signal in the pressed state is realized, and ensuring the stable work of the touch function in the pressed state. Third, due to the deformable property of the second spring 153, the pressing process of the key 130 can continue after the second spring 153 abuts against the conductive sheet 120, and the conductive sheet 120 and the auxiliary conductive structure 150 will not prevent the pressing displacement of the key 130, ensuring that the displacement of the key 130 can trigger the corresponding element, and by virtue of the deformability of the second spring 153, the activation of the second conduction path can be realized in part or all of the stroke of the key 130 being pressed. In addition, the auxiliary conductive structure 150 selects the second spring 153, which has a simple design structure, simplifies the structure of the touch and press dual-purpose key, improves the reliability, and reduces the production cost.

[0102] As a first form of cooperation between the second spring 153 and the conductive sheet 120, in some embodiments, the second end of the second spring 153 is arranged separately from the conductive sheet 120 when the first abutting surface 1314 is in contact with the conductive sheet 120. In this way, in the non-pressed state (including the natural state and the touch state), only the first conduction path works, and the second conduction path is not activated due to the inability of the second spring 153 to connect with the conductive sheet 120. Specifically, when the key 130 is in the natural state or the touch state, the first conduction path is in contact with the conductive sheet 120 through the first abutting surface 1314 to transmit the touch signal to the circuit system of the electronic device. At this time, the second conduction path is in a non-working state because the second end of the second spring 153 is not in contact with the conductive sheet 120, and thus an effective circuit connection cannot be formed. When the user presses the key 130, the first abutting surface 1314 is separated from the conductive sheet 120, and the first conduction path is interrupted, at which time the second end of the second spring 153 gradually approaches the conductive sheet 120 and eventually realizes contact with the conductive sheet 120, thereby forming the second conduction path. At this time, the second conduction path is activated and continues to work, ensuring that the touch signal can still be transmitted in the pressed state.

[0103] The design can selectively activate the first conduction path or the second conduction path through switching of the first conduction path and the second conduction path, ensuring the stability and flexibility of touch signal transmission in the pressed and non-pressed states. In the non-pressed state, the second conduction path does not work, effectively avoiding unnecessary signal transmission interference and maintaining the purity of the touch signal. The present embodiment can be applied to the working scenarios a, b and c described above, and will not be described here again.

[0104] As a second form of cooperation between the second spring 153 and the conductive sheet 120, in some embodiments, the second end of the second spring 153 is in abutment with the conductive sheet 120 when the first abutment surface 1314 is in contact with the conductive sheet 120. In this embodiment, in the non-pressed state (including the natural state and the touched state), both the first conduction path and the second conduction path are in the activated state. Specifically, when the key 130 is in the natural state or the touched state, the first conduction path is in contact with the conductive sheet 120 through the first abutment surface 1314, and the touch signal is transmitted to the circuit system of the electronic device. At this time, the second conduction path is in abutment with the conductive sheet 120 through the second end of the second spring 153, and the touch signal is transmitted to the circuit system of the electronic device, forming an effective circuit connection. When the user presses the key 130, the first abutment surface 1314 is out of contact with the conductive sheet 120, and the first conduction path is interrupted. At this time, the second end of the second spring 153 can be more stably abutted on the conductive sheet 120 after being compressed and deformed, and the second conduction path continues to work, ensuring that the touch signal can still be transmitted in the pressed state. This design makes the first conduction path work and the second conduction path work in the non-pressed state. After the pressing action is started, the key 130 and the conductive sheet 120 are always in communication, and the second conduction path is always in working state. In the switching process of touch and pressing action, the assembly does not have touch signal transmission breakpoint.

[0105] In this embodiment, in the non-pressed state, both the first conduction path and the second conduction path work. When the pressing action is started, the first conduction path is interrupted, and the second conduction path continues to work, ensuring that the key 130 and the conductive sheet 120 are always in communication. It is especially suitable for scenarios that require stable and continuous touch signal transmission, especially for devices that frequently switch operation modes, to ensure that the touch signal can operate stably in high-frequency pressing interaction, so that the device can process the pressing action without stopping the touch signal transmission. For specific use scenarios, please refer to the descriptions of scenarios d and e in the foregoing, which will not be repeated here.

[0106] In some embodiments, as Figures 2-3 , Figure 8 , Figures 11-12As shown, the bracket 110 of the pressing assembly is provided with a receiving groove 114 matching the shape of the keycap 132 on one side of the keycap 132. The profile of the receiving groove 114 is adapted to the outer profile 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 in the axial direction during pressing and prevent deviation or skew. In the design of the receiving groove 114, the groove wall closely matches the outer edge of the keycap 132, so that the keycap 132 does not unnecessarily swing or rub during pressing, thereby ensuring the smoothness and comfort of the pressing action. In addition, the groove bottom of the receiving groove 114 is designed to a certain depth to provide a limiting effect on the axial movement of the keycap 132 in the pressed state. Specifically, the keycap 132 can move freely along the groove wall of the receiving groove 114 during pressing, but its axial movement is limited by the groove bottom of the receiving groove 114, avoiding the keycap 132 from exceeding the set movement range. In this way, the limiting effect of the groove bottom effectively prevents the keycap 132 from moving excessively during pressing, thereby avoiding damage to the switch piece 160 caused by excessive extrusion of the key shaft 131, ensuring the service life and stability of the switch piece 160. That is, the receiving groove 114 not only enhances the stability of the cooperation between the keycap 132 and the bracket 110, but also realizes the movement limitation of the keycap 132, avoiding the adverse effects of excessive pressing or uncontrolled movement of the keycap 132 on the internal switch piece 160, greatly improving the reliability and operation experience of the key 130.

[0107] In some embodiments, as shown in the figure, the reset member 140 of the pressing assembly is a spring arranged between the keycap 132 and the bracket 110, and the bracket 110 is provided with a third mounting groove 115 on the side thereof facing the keycap 132 for mounting the spring. The working principle of the spring is to store mechanical energy, and when the key 130 is pressed by an external force, the spring is compressed and stores elastic potential energy; when the external force is removed, the spring releases the stored energy to push the key 130 back to the initial position, thereby completing the reset action and enabling the key 130 to automatically reset to the initial state after the pressing is released. The design of the third mounting groove 115 allows the spring serving as the reset member 140 to be maintained in the correct position when the key 130 is pressed, avoiding the spring from being displaced or unnecessarily deformed, 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 be adapted to the outer surface of the spring, thereby fixing the position of the spring and preventing it from being displaced or excessively shaken during the working process, and limiting the spring force direction 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 pressing and resetting of the keycap 132 to provide sufficient restoring force. The provision of the third mounting groove 115 not only provides a mounting position for the spring, but also precisely controls the position and stress state of the spring, improves the stability of the reset function, avoids possible damage or failure of the spring, and enables the spring to maintain good performance during repeated pressing.

[0108] In some embodiments, as shown in the figure, the keycap 132 of the pressing assembly is provided with a limiting groove 1321 opposite the third mounting groove 115 on the side thereof facing the bracket 110, and one end of the spring is limited in 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 being tilted or radially displaced during the working process, thereby avoiding uneven stress on the spring and ensuring smooth and consistent pressing and resetting of the keycap 132, and improving the service life and overall stability of the key 130. In addition, the limiting groove 1321 cooperates with the third mounting groove 115, and the two ends of the spring are respectively limited and stabilized by the corresponding third mounting groove 115 and limiting groove 1321, thereby further avoiding the problems of uneven stress on the keycap 132 or unsmooth operation of the key 130 caused by unstable spring, and ensuring that the spring will not be radially displaced or tilted during the working process.

[0109] In some embodiments, as Figure 12As shown, the spring of the pressing assembly, the third mounting slot 115 and the limiting slot 1321 are correspondingly provided with two groups and symmetrically distributed on both sides of the key shaft 131. Each side of the key shaft 131 is provided with a group of third mounting slot 115 and limiting slot 1321, and the two ends of the spring are matched with these slot bodies respectively. This design effectively avoids eccentric force or asymmetric pressure caused by unilateral design, thereby enhancing the overall stability of the switch assembly. The symmetrically distributed springs on both sides remain balanced during the pressing and resetting of the key 130, avoiding the incomplete resetting or unresponsive pressing of the key 130 caused by uneven force on the spring. At the same time, such design can also reduce the wear and tear of components caused by uneven force.

[0110] It should be noted that, as shown in Figure 2 , Figure 8 and Figure 11 , a person skilled in the art can use one of them as the spring of the reset member 140 as the first spring 151 according to the needs, so that it can realize the resetting function and cooperate with the conductive column 152 to form the first conduction path. Similarly, the third mounting slot 115 for accommodating the spring of the reset member can be used as the first mounting slot 112 for accommodating the first spring 151.

[0111] In some embodiments, the conductive sheet 120 in the pressing assembly is connected to the bracket 110 in a fit manner, and the hole diameter of the second shaft hole 121 is smaller than the outer diameter of the first shaft section 1311 and larger than the outer diameter of the second shaft section 1312.

[0112] The conductive sheet 120 is attached to the support 110 to achieve close cooperation between the conductive sheet 120 and the support 110, forming a firm and stable structure. The conductive sheet 120 can be attached to the support 110 in various ways, such as by screwing, buckling, heat pressing, or gluing, so that the conductive sheet 120 does not loosen or fall off during the entire use of the key 130. The contact surface between the conductive sheet 120 and the support 110 can be precisely processed to make the surface smoother and flatter, thereby increasing the contact area between the two and further enhancing the fixing effect. In this way, the conductive sheet 120 can effectively bear the axial force of the key 130. The conductive sheet 120 is attached to the support 110, and under the resetting force of the reset member 140, the first abutting surface 1314 of the first shaft section 1311 forms an abutting force with the side of the conductive sheet 120 away from the support 110 in the natural state, further enhancing the stability of the conductive sheet 120. This design not only ensures that the conductive sheet 120 is firmly fixed to the support 110, but also transmits the axial force of the first shaft section 1311, further improving the overall stability and durability of the assembly. The first abutting surface 1314 of the first shaft section 1311 forms a close contact with the side of the conductive sheet 120 away from the support 110. This contact is not a simple support, but through the transmission of axial force, the conductive sheet 120 is more firmly fixed to the support 110, preventing the conductive sheet 120 from shifting or loosening. Especially during the pressing process with greater force, the first abutting surface 1314 can effectively transmit the force evenly to the conductive sheet 120, and through the conductive sheet 120, the pressure is transmitted to the support 110 with bearing function. In the repeated pressing and resetting process, the conductive sheet 120 can rely on this additional abutting force to reduce stress concentration due to vibration or impact, so that the conductive sheet 120 is not easily damaged or worn during long-term use. Even under extreme or high-frequency working conditions, the key 130 and the conductive sheet 120 can still maintain good performance.

[0113] The second shaft hole 121 has a hole diameter smaller than the outer diameter of the first shaft segment 1311, which allows the first shaft segment 1311 to effectively abut against the conductive sheet 120. This design ensures that the contact between the first shaft segment 1311 and the conductive sheet 120 remains stable during the operation of the key 130, effectively preventing damage or instability of the key 130 due to excessive movement. On the other hand, the second shaft hole 121 has a hole diameter larger than the outer diameter of the second shaft segment 1312, which allows the key shaft 131 to move freely in the second shaft segment 1312 without being interfered by the conductive sheet 120. That is, the second shaft segment 1312 can smoothly move axially when passing through the second shaft hole 121, ensuring the normal pressing and resetting functions of the key 130. Through this structure, the axial movement range of the key 130 is effectively controlled, while ensuring the smooth operation of the key 130, avoiding the problem of unsmooth operation of the key 130 due to excessive friction or unsmooth movement.

[0114] This embodiment ensures the balance between limiting and moving of the key shaft 131 by skillfully designing the size of the second shaft hole 121 of the conductive sheet 120. The key shaft 131 can effectively contact the conductive sheet 120 to limit the key 130 when the key 130 is reset, and can freely move axially when normally pressed, ensuring the stability and comfort of the key 130. This design not only improves the durability of the pressing assembly, but also optimizes the user experience, ensuring the responsiveness and long-term reliability of the key 130.

[0115] In some embodiments, the first shaft hole 111 has a hole diameter larger than the maximum outer diameter of the key shaft 131, and the second shaft hole 121 penetrates to the edge of the conductive sheet 120 to form a notch 123 as shown in Figure 10 The hole diameter of the first shaft hole 111 is larger than the maximum outer diameter of the key shaft 131, which ensures that the key shaft 131 can smoothly penetrate the entire first shaft hole 111. The maximum outer diameter of the key shaft 131 is slightly smaller than the hole diameter of the first shaft hole 111, which not only allows the key shaft 131 to be freely inserted from the first side of the bracket 110, but also ensures that the first shaft segment 1311 can be exposed from the second side during the installation of the key 130. The free movement of the key shaft 131 in the first shaft hole 111 ensures the smooth movement of the key 130 assembly, avoiding the problem of blockage or jamming due to the small first shaft hole 111.

[0116] Since the first shaft segment 1311 will abut against the conductive sheet 120 during operation, it is inevitable that the first shaft segment 1311 cannot pass through the second shaft hole 121 of the conductive sheet 120. Therefore, how to quickly assemble the second shaft hole 121 on the key shaft 131 during assembly has become a problem to be solved. In this embodiment, the second shaft hole 121 is formed through the edge of the conductive sheet 120 to form a notch 123, which can realize the detachable assembly of the key 130, the bracket 110 and the conductive sheet 120. Through the notch 123, the conductive sheet 120 can move radially during assembly, so that the second shaft hole 121 of the conductive sheet 120 can be sleeved on the second shaft segment 1312 of the key shaft 131, and the second shaft hole 121 is no longer moved in the axial direction. This design greatly simplifies the installation steps of the conductive sheet 120, and enhances the convenience of later maintenance and replacement by providing detachability. The specific assembly process is shown in the following example.

[0117] Step one, the key shaft 131 of the key 130 is inserted into the first shaft hole 111 from the first side of the bracket 110, and the first shaft segment 1311 is continued to be stretched out from the second side of the bracket 110. At this time, the conductive sheet 120 has not been installed to the bracket 110, the first shaft segment 1311 can be freely stretched out to the second side of the bracket 110, and completely exposed outside the bracket 110, and part of the second shaft segment 1312 is also exposed outside the bracket 110.

[0118] Step two, install the conductive sheet 120. At this time, the notch 123 on the conductive sheet 120 is close to the second shaft segment 1312, and the conductive sheet 120 is moved radially through the notch 123 on the conductive sheet 120 and the second shaft hole 121, so that the second shaft hole 121 is sleeved on the second shaft segment 1312.

[0119] Step three, fix the conductive sheet 120 to ensure that the conductive sheet 120 is firmly connected to the bracket 110.

[0120] The above assembly process does not require complex tools or high-precision operation, which is convenient for production and assembly. The design of the notch 123 connected to the second shaft hole 121 makes the conductive sheet 120 easy to assemble and disassemble, which is very important for later maintenance and replacement, especially in the case of long-term use or frequent maintenance of electronic products. By designing reasonable hole diameter matching and shaft segment limiting structure, deviation or misoperation that may occur during assembly is avoided, ensuring accurate matching of each component, thereby improving the overall reliability and stability of the product.

[0121] In some embodiments, as Figures 6-8 , Figure 10 , Figure 13As shown, the conductive sheet 120 includes an angularly arranged first conductive sheet 124 fixed on the support 110 and a second conductive sheet 125. The key 130 is movably arranged on the support 110 to realize contact or separation with the first conductive sheet 124. The second conductive sheet 125 is used to be connected with the second circuit board 200 through a conductive connecting piece. During the movement of the key 130 relative to the support 110, there is a state of contact with the first conductive sheet 124. At this time, after the key 130 is touched, the key 130, the first conductive sheet 124, the second conductive sheet 125 and the conductive connecting piece 700 sequentially transmit the touch electric signal to form a first conduction path, and then the touch signal can be transmitted to the second circuit board 200. In the related art, the conductive connecting piece usually adopts a conductive spring sheet. The conductive spring sheet usually includes a fixed part and an elastic part. The fixed part is used to be fixedly connected with a circuit board and the like structure to realize connection with the internal circuit. The elastic part is used to be non-fixedly abuttingly connected with an external circuit. Specifically, the elastic part completes contact with the external circuit by relying on the deformation amount of the elastic part. When the conductive spring sheet is installed, external force is needed to make the elastic part deform to obtain sufficient elastic force, so that the elastic part can stably extrude the external circuit. However, the elastic part of the conductive spring sheet in the related art is in a non-deformed state in a natural state before installation. During the installation process, the non-deformed elastic part in the natural state needs to be adjusted to a deformed state to generate sufficient elastic force. This process needs to make the elastic part have a large deformation amount, which leads to the complexity of the operation process. Based on this, the embodiment of the present application further provides an optimized conductive connecting piece.

[0122] As Figures 14-16As shown, the main structure of the conductive connecting piece 700 provided by the embodiment of the present application includes a first substrate 710, a wing plate 720 and an elastic sheet 730. The back of the first substrate 710 is configured to be connected with the circuit board, and the first substrate 710 is taken as an example to be connected with the second circuit board 200 in the present text; the wing plate 720 is provided with two, and each is extended from the opposite side of the first substrate 710 to the front side of the first substrate 710, the free end of one wing plate 720 is bent to form a first limiting part 740 towards the other wing plate 720; the elastic sheet 730 includes a vertical plate 731, a first elastic arm 732, a bending section 733 and a second elastic arm 734 which are sequentially arranged, the vertical plate 731 is connected with the first substrate 710, the bending section 733 is located at one end of the elastic sheet 730 away from the first substrate 710 and protrudes from the free end of the wing plate 720, the second elastic arm 734 extends from the bending section 733 towards the first substrate 710 and extends into the two wing plates 720, the second elastic arm 734 is formed with a second limiting part 750, the second limiting part 750 is abutted on one side of the first limiting part 740 towards the first substrate 710 to make the elastic sheet 730 in a deformed state, the reset force generated by the elastic sheet 730 makes the second limiting part 750 always have a tendency to move away from the first substrate 710.

[0123] The first substrate 710 is the core component of the conductive connecting piece 700, and the connection of the back of the first substrate 710 with the second circuit board 200 completes the electrical connection and ensures the stability and reliability of the connection of the conductive connecting piece 700 with the second circuit board 200.

[0124] The design of the wing plate 720 not only enhances the stability of the structure, but also ensures that the elastic sheet 730 can be kept in a preset deformed state in a natural state through cooperation with the elastic sheet 730.

[0125] The vertical plate 731 in the elastic sheet 730 is connected with the first substrate 710 to play a supporting and connecting role; the first elastic arm 732 is connected with the vertical plate 731 and has elasticity, responsible for providing the deforming ability of the elastic sheet 730 during installation; the bending section 733 is located at one end of the elastic sheet 730 away from the first substrate 710 and protrudes from the free end of the wing plate 720, which is used to contact and connect with the devices of the external circuit structure, the bending section 733 enables the conductive connecting piece 700 to realize electrical contact with the external circuit (such as sensors, connectors, conductive parts and other devices); the second elastic arm 734 extends from the bending section 733 towards the first substrate 710 and enters between the wing plates 720, used to abut against the front of the first substrate 710 to deform and provide further elastic force when necessary.

[0126] The second elastic arm 734 of the elastic sheet 730 is provided with a second limiting part 750, which cooperates with the first limiting part 740 on the wing plate 720. Through the cooperation, the elastic sheet 730 is in a preset deformed state in a natural state, ensuring that the elastic sheet 730 remains in a stable elastic state without external force.

[0127] The design of the embodiment makes the elastic sheet 730 remain in a preset deformed state in a natural state through the cooperation of the first limiting part 740 and the second limiting part 750. During installation, only a small amount of deformation is required to deform the elastic sheet 730 to the appropriate position. The specific installation steps can be listed as follows: Step one, align the conductive connecting piece 700 with the predetermined position on the second circuit board 200, so that the back of the first base plate 710 forms a stable connection with the second circuit board 200. At this time, the elastic sheet 730 is already in a preset deformed state due to the cooperation of the first limiting part 740 and the second limiting part 750; Step two, apply an external force to the elastic sheet 730 to further slightly deform the elastic sheet 730, so that the second limiting part 750 is separated from the first limiting part 740 and approaches the first base plate 710, so that the bending segment 733 of the elastic sheet 730 gradually approaches the first base plate 710 to obtain the final installation state. After the elastic sheet 730 is slightly deformed in the second step, the bending segment 733 can form a stable abutment with the external structure, ensuring that the electrical connection of the conductive connecting piece 700 is reliable.

[0128] The embodiment makes the elastic sheet 730 remain in a preset deformed state in a natural state through the cooperation of the first limiting part 740 and the second limiting part 750. Only a small amount of deformation of the elastic sheet 730 is required to obtain the required elastic abutment force. Compared with the unconstrained elastic sheet 730 in a natural state, the deformation adjustment amount during installation is smaller, reducing the operation steps that require a large amount of deformation in traditional technology, making the installation process more simple and efficient. Moreover, since the elastic sheet 730 is already in a suitable deformed state in a natural state, the deformation amount during installation is smaller, thereby reducing the repeated bending and deformation adjustment range of the material and prolonging the service life of the conductive connecting piece 700.

[0129] With the volume of electro-optical products decreasing, the integration of the internal structure is also increasing. This means that the available space inside the product is becoming increasingly limited, and the need for external tools and significant adjustments during installation is minimized. Traditional installation methods often require a large amount of deformation or external force to complete the installation, while the first limiting portion 740 and the second limiting portion 750 cooperate to ensure that the elastic sheet 730 is in a pre-set deformed state in a natural state. Only by applying an external force can the elastic sheet 730 be further slightly deformed and installed without the need for significant deformation and adjustment, avoiding the need for a large amount of space for operation in the traditional installation method. In line with the trend of existing electronic products towards miniaturization and thinness, the design of the conductive connector 700 not only needs to ensure the stability of the electrical connection, but also fully considers the compactness and integration of the internal structure of the electronic product. The scene use requirements, therefore, the traditional installation method often faces the problem of small space and inconvenient operation. The embodiment optimizes the deformation adjustment method of the elastic sheet 730, which exactly meets these new requirements.

[0130] In some embodiments, as shown in the figure, the vertical plate 731 of the conductive connector 700 is connected between the first elastic arm 732 through the continuously arranged first bending section 735 and the second bending section 736, and the bending directions of the first bending section 735 and the second bending section 736 are opposite.

[0131] The opposite bending design of the continuously arranged first bending section 735 and the second bending section 736 can effectively disperse the deformation stress, so that the elastic sheet 730 can be more uniformly subjected to external force during operation. Compared with traditional design, the continuous opposite bending arrangement allows the elastic sheet 730 to achieve ideal deformation under smaller force, thereby enhancing the overall elasticity. The opposite bending directions of the first bending section 735 and the second bending section 736 provide elastic forces that oppose each other, not only allowing the elastic sheet 730 to maintain a certain flexibility in different deformation states, but also optimizing the deformation response of the elastic sheet 730, which is conducive to enhancing the deformation and reset capabilities of the conductive connector 700. The deformation force during installation is small, and the elastic sheet 730 can quickly recover to the initial state where the first limiting portion 740 and the second limiting portion 750 abut each other after the external force is removed.

[0132] In some embodiments, as shown in the figures, the protruding ears 760 are formed on the wings 720 of the conductive connector 700, which shield the first bending section 735 and / or the second bending section 736. Since the bending sections are usually the most fatigue-damaged parts of the elastic sheet 730, especially during high-frequency deformation or installation, cracks, bending or excessive wear are likely to occur in the bending sections, which need to be protected from physical impact from other structures. The protruding ears 760 can effectively reduce the possibility of the bending sections directly contacting external objects by physical shielding, avoiding direct impact and damage to these vulnerable components from external factors, which not only improves the service life and stability of the conductive connector 700, but also reduces maintenance costs.

[0133] In some embodiments, as shown in the figures, the ears 760 on one of the wings 720 are bent towards the other wing 720 to form a second substrate 770 parallel to the first substrate 710. By bending the ears 760 on the wings 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 choose the appropriate connection method according to different application requirements, making the conductive connector 700 more widely applicable.

[0134] The second substrate 770 is similar to the first substrate 710 and is also a non-elastic structure. Compared to the dynamic extrusion connection provided by the combination of the elastic sheet 730 and the first substrate 710, the combination of the second substrate 770 and the first substrate 710 provides a static connection scheme. By connecting the second substrate 770 to an external circuit board, the conductive connector 700 can complete electrical connection without relying on elastic deformation, making it suitable for situations where high connection stability is required. The first substrate 710 and the second substrate 770 can be used for static connection between two circuit boards, respectively, making the product more flexible and allowing different connection schemes to be selected according to requirements. The design of the second substrate 770 increases the stability of the connection, especially in situations where high mechanical stress is required. As a non-elastic structure, the second substrate 770 can effectively prevent poor electrical contact at the connection point caused by deformation, thereby improving the service life and electrical performance of the entire conductive connector 700.

[0135] The cooperation between the elastic sheet 730 and the first substrate 710 is mainly used to realize the extrusion contact connection between the second circuit board 200 and the external circuit structure. Such extrusion contact connection can provide more stable electrical contact during installation, ensuring the reliability of the connection. The static connection function of the second substrate 770 provides another option, making the connection mode more flexible. By providing the dual connection mode of the elastic sheet 730 and the second substrate 770, the optimal connection scheme can be selected according to specific needs during installation. For example, if it is necessary to maintain strong physical connection strength during installation, the static connection mode of the second substrate 770 will be a preferred scheme. For application scenarios that require dynamic connection or require higher flexibility, the cooperation between the elastic sheet 730 and the first substrate 710 can be selected. Users can flexibly select appropriate connection modes according to specific needs, ensuring the reliability of electrical connection and improving the adaptability of products to meet the needs of different environments.

[0136] In some embodiments, as shown in the figure, a reinforcing rib 780 is arranged at the connection between the wing plate 720 and the first limiting portion 740. The cooperation between the first limiting portion 740 and the second limiting portion 750 requires certain mechanical support, especially in the initial state, the elastic sheet 730 is limited in the preset deformation state, the first limiting portion 740 and the second limiting portion 750 are always in abutting state, and the first limiting portion 740 will bear certain pressure or stress. The arrangement of the reinforcing rib 780 can effectively enhance the structural strength of the first limiting portion 740, thereby preventing it from deforming, damaging or failing due to fatigue during stress, and maintaining stability for a longer period of time.

[0137] In some embodiments, as shown in the figure, a stress relief hole 790 is formed at the connection between the wing plate 720 and the first substrate 710. In traditional structural design, the connection or bending part is often a stress concentration area, and long-term stress may cause material fatigue, cracking or failure. By arranging the stress relief hole 790 at the connection between the wing plate 720 and the first substrate 710, the presence of the stress relief hole 790 can make the stress evenly distributed along the hole wall, avoiding the local stress concentration phenomenon in traditional design, which can effectively disperse stress and reduce the concentration of stress at the connection, thereby reducing the risk of damage to the component during use. The design of the stress relief hole 790 can also make the component have lighter weight and lower material cost.

[0138] In the specific use process, the bending section 733 of the conductive connecting piece 700 of the foregoing embodiment is in abutment with the second conductive sheet 125. The first conductive sheet 124 is fixedly connected with the support 110, and the second conductive sheet 125 is in physical contact with the elastic sheet 730 by being in contact with the bending section 733 of the conductive connecting piece 700, so that the elastic sheet 730 is extruded and deformed, thereby realizing the extrusion connection between the second conductive sheet 125 and the conductive connecting piece 700. The first substrate 710 of the conductive connecting piece 700 is connected with the second circuit board 200 through the back surface thereof, thereby ensuring the stable electrical connection between the circuit system and the pressing assembly. The bending section 733 of the elastic sheet 730 of the conductive connecting piece 700 is in abutment on the second conductive sheet 125 of the conductive sheet 120 and is extruded by the second conductive sheet 125, so that the elastic sheet 730 is further deformed relative to the initial state when not installed, the first limiting portion 740 and the second limiting portion 750 are separated from each other, thereby realizing the stable connection between the elastic sheet 730 and the second conductive sheet 125. The conductive connecting piece 700 realizes the connection between the conductive sheet 120 and the second circuit board 200 of the circuit system in the electronic device, and can transmit the touch electrical signal under the touch function to the circuit system of the electronic device.

[0139] The design of the conductive connecting piece 700 makes the elastic sheet 730 only need to be slightly deformed and adjusted during installation to obtain a stable electrical connection, and the deformation adjustment amount during installation is smaller, thereby reducing the operation steps requiring a large deformation amount in the conventional technology and making the installation process more simple and efficient.

[0140] In some embodiments, as Figure 2 , Figures 6-8 , Figures 10-13As shown, the bracket 110 is formed with a positioning protrusion 119 on one side thereof facing the first conductive sheet 124, and the first conductive sheet 124 is formed with a second through hole 126 matched with the positioning protrusion 119. The cooperation between the positioning protrusion 119 and the second through hole 126 is used to ensure that the conductive sheet 120 is quickly positioned when assembled to the bracket 110, avoiding deviation or mispositioning. The specific installation steps can be as follows: first, the second through hole 126 is sleeved on the positioning protrusion 119, ensuring that the conductive sheet 120 is attached to the surface of the bracket 110. Through this cooperation, the second through hole 126 of the conductive sheet 120 is accurately positioned on the predetermined position of the bracket 110 during preliminary assembly; then, after ensuring that the second through hole 126 is sleeved on the positioning protrusion 119, the first conductive sheet 124 is gently rotated around the positioning protrusion 119 until the first through hole 122 is aligned with the second mounting groove 113, at this time, the conductive sheet 120 is in the correct angle and position, preparing for the next fixing step; finally, when the first through hole 122 is aligned with the second mounting groove 113, the conductive post 152 is inserted into the first through hole 122 and the second mounting groove 113, and the conductive post 152 is screwed into the second mounting groove 113 through screwing, completing the stable fixation of the conductive sheet 120.

[0141] Through the cooperation between the positioning protrusion 119 and the second through hole 126, the conductive sheet 120 can be accurately fixed at the predetermined position during installation, avoiding deviation during assembly and improving assembly accuracy. This design can accurately butt joint the conductive sheet 120 to the correct position through simple rotation operation, without the need for complex adjustment or additional tools, reducing the positional error of adjustment and inspection during assembly, thereby improving the overall assembly efficiency. The cooperation between the positioning protrusion 119 and the second through hole 126 not only ensures accurate initial positioning, but also enables the conductive sheet 120 to be fixed at two points through the positioning protrusion 119 and the conductive post 152 after installation, enhancing the stability of the connection.
