[0028] In a possible implementation, the first elastic member and the second elastic member together form a first window area corresponding to the first protrusion, and the third elastic member and the fourth elastic member together form a second window area corresponding to the second protrusion.
[0029] Through the technical solution of this embodiment, when a user presses on the touch assembly, the raised portion will not interfere with or affect the elastic deformation of the elastic member, thereby more reliably ensuring the press detection performance of the touch panel.
[0030] In a possible implementation, the first protrusion and the second protrusion are reinforcement portions provided on the upper surface of the fixing platform, and the reinforcement portions and the fixing platform are separate structures.
[0031] Through the technical solution of this embodiment, the protrusion and the fixing platform are separate structures, which is beneficial to improving the production efficiency of the touch panel and reducing the overall manufacturing cost of the touch panel.
[0032] In one possible implementation, the first raised portion includes at least one first connecting hole, the second raised portion includes at least one second connecting hole, the fixed platform has at least one third connecting hole corresponding to the at least one first connecting hole, and the fixed platform has at least one fourth connecting hole corresponding to the at least one second connecting hole, the connecting member passes through the at least one first connecting hole and the at least one third connecting hole to connect the fixed platform and the first raised portion, and the connecting member also passes through the at least one second connecting hole and the at least one fourth connecting hole to connect the fixed platform and the second raised portion.
[0033] Through the technical solution of this embodiment, the first protrusion and the second protrusion can be connected to the fixed platform through connecting parts respectively, which simplifies the assembly process and facilitates the disassembly of the fixed platform and the entire touch panel, making it easier to maintain the production line.
[0034] In a possible implementation, the first contact point is located in a central area of the first raised portion, and the second contact point is located in a central area of the second raised portion.
[0035] In one possible implementation, the first contact is a first adjusting screw installed on the first protrusion, and the height of the first adjusting screw relative to the first protrusion can be adjusted; the second contact is a second adjusting screw installed on the second protrusion, and the height of the second adjusting screw relative to the second protrusion can be adjusted.
[0036] In this embodiment, the height-adjustable adjustment screw can better adapt to the travel switch, making the travel switch more sensitive and accurate in sensing press pressure. Furthermore, the height-adjustable adjustment screw can tolerate deformation of the fixed platform and thickness tolerances of the travel switch. In other words, even if the fixed platform deforms and / or the travel switch has thickness tolerances, the adjustment screw can be used to adjust the distance and interaction force between the adjustment screw and the travel switch, ensuring a good fit between the travel switch and the adjustment screw, thereby maintaining the touchpad's press detection performance.
[0037] In a possible implementation, the first contact is a first boss installed on the first raised portion and protruding toward the first touch component, and the second contact is a second boss installed on the second raised portion and protruding toward the second touch component.
[0038] In this embodiment, the fixed platform is used to cooperate with the contacts of the travel switch, which is simple to implement and has a low manufacturing cost, thereby improving the production efficiency of the touch panel and reducing the overall manufacturing cost of the touch panel.
[0039] In one possible implementation, the first contact is a first T-shaped screw provided on the first raised portion, with the head of the first T-shaped screw facing the first travel switch, and the second contact is a second T-shaped screw provided on the second raised portion, with the head of the second T-shaped screw facing the second travel switch.
[0040] Through the technical solution of this embodiment, there is no need to adjust the distance and interaction force between the touch screen and the travel switch by adjusting the screw. Instead, the T-shaped screw and the rubber layer can cooperate with each other to keep the T-shaped screw and the travel switch in a pre-pressed state suitable for the user's pressing action, thereby more sensitively and conveniently detecting the user's pressing on the touch pad, and also ensuring the user's pressing feel on the touch pad.
[0041] In a possible implementation, the edge of the first side of the first main support member and the edge of the fourth side of the second main support member are provided with limiting portions, and the limiting portions are used to achieve positioning of the first main support member and the second main support member.
[0042] Through the technical solution of this embodiment, the main support member serves as the central component in the touch panel, ensuring the overall strength and structural stability of the touch panel. A limiting portion is provided on the main support member to achieve the limitation of the main support member in the electronic device, which can more reliably ensure the overall limitation of the touch panel in the electronic device, thereby more reliably ensuring the installation and use of the touch panel in the electronic device.
[0043] In one possible implementation, the edge of the fixed platform is bent upward to form a step structure, and the side wall of the step structure forms a limiting hole. The limiting hole cooperates with the limiting portion to enable the fixed platform to limit the first main support member and the second main support member.
[0044] The technical solution of this embodiment allows the main support member to be limited by the fixed platform in the touchpad without the need for additional limiting holes in the electronic device. This ensures the touchpad itself has a relatively stable structure while simplifying its installation in the electronic device and facilitating its removal and repair.
[0045] In a second aspect, an electronic device is provided, comprising a housing, and the touch panel according to the first aspect or any possible implementation manner of the first aspect, wherein the touch panel is mounted on the housing. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] The technical solution in this application will be described below with reference to the accompanying drawings.
[0062] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
[0063] The present application relates to a touchpad (or also called a touchpad). Specifically, the touchpad can provide a touch and press interface that interacts with a user's finger. In a press interface, the touchpad can sense the user's press operation to perform corresponding press feedback or instruct the electronic device where it is located to perform a corresponding function. The press interface can act as a "button" function. In a touch interface, the touchpad can be used to sense the position and movement of the user's finger to perform corresponding touch feedback or instruct the electronic device where it is located to perform a corresponding function. The touch interface can act as a "mouse" function.
[0064] The touch panel can be applied to any human-computer interaction device, such as a laptop computer, a tablet computer, a mobile phone, a smart wearable device, a smart door lock, an automated teller machine (ATM), etc., and the embodiments of the present disclosure are not limited to this.
[0065] With technological innovation and advancement, touchpads are becoming increasingly powerful, while consumers are also increasingly demanding larger touchpad sizes and higher feedback. However, when faced with large-sized touchpads, traditional press-sensitive touchpads struggle to provide a small press trigger travel, resulting in poor press feedback and impacting the user experience. In light of this, the present application provides a touchpad that, while maintaining a large size, achieves full-area pressability and provides a small press trigger travel, thereby enhancing the user's full-area press tactile experience.
[0066] FIG1 and FIG2 respectively show a schematic cross-sectional view and a schematic exploded view of a touch panel 1 provided in an embodiment of the present application.
[0067] As shown in Figures 1 and 2, the touch panel 1 includes a first touch module 10, a second touch module 20, a fixing platform 500, and a flexible printed circuit (FPC) 600. The first touch module 10 is disposed on the left side of the touch panel 1, and the second touch module 20 is disposed on the right side of the touch panel 2 and adjacent to the first touch module 10. The FPC 600 is disposed on the lower surfaces of the first touch module 10 and the second touch module 20 for electrically connecting the first touch module 10 and the second touch module 20. The fixing platform 500 is disposed below the first touch module 10 and the second touch module 20. The first touch module 10 includes a first touch assembly 100 and a first support assembly 200, and the second touch module 20 includes a second touch assembly 300 and a second support assembly 400.
[0068] By providing the first touch module 10 and the second touch module 20, the touch panel 1 has a larger area and size, and realizes full-area pressing of the touch panel and provides a smaller pressing trigger stroke. In addition, the touch panel 1 electrically connects the first touch module 10 and the second touch module 20 through the FPC 600, and can conduct the electrical signals generated by the user pressing the first touch module 10 and the second touch module 20 to each other, thereby saving manufacturing costs and reducing the configuration complexity of touch sensing and pressing detection.
[0069] Specifically, the first touch component 100 is used to receive a user's press, and a first travel switch 101 is provided on the lower surface of the first touch component 100. The second touch component 300 is used to receive a user's press, and a second travel switch 301 is provided on the lower surface of the second touch component 300.
[0070] The first supporting assembly 200 includes a first main supporting member 210 , a first elastic member 220 , and a second elastic member 230 .
[0071] The first main support member 210 is disposed at the edge of the lower surface of the first touch assembly 100. The first main support member 210 is frame-shaped and has a first side 211 and a second side 212 opposing each other. Optionally, the frame has a hollow area. The first elastic member 220 and the second elastic member 230 are disposed below the first main support member 210 and are symmetrically connected to the first main support member 210 along the plane in which the first main support member 210 lies.
[0072] The fixed platform 500 is arranged below the first elastic member 220 and the second elastic member 230. The first elastic member 220 is connected between the first side 211 of the first main support member 210 and the fixed platform 500. The second elastic member 230 is connected between the second side 212 of the first main support member 210 and the fixed platform 500. The fixed platform 500 is provided with a first contact point 501 on the surface facing the first touch component 100.
[0073] When any position of the first touch component 100 is pressed, the first touch component 100 is forced to move downward, the first elastic member 220 and the second elastic member 230 are elastically deformed, and the first contact point 501 on the fixed platform 500 contacts and triggers the first travel switch 101 on the first touch component 100.
[0074] Specifically, the first touch component 100 can be a plate-shaped structure, which is convenient for providing a press interface for the user. The first touch component 100 may include: a first circuit board 120. After the touch panel 1 where the first touch component 100 is located is assembled on the electronic device, the first circuit board 120 can be set on the lower surface of the first cover plate 110, and the user presses the first circuit board 120 by pressing the first cover plate 110. Alternatively, in some embodiments, the first touch component 100 may directly include: a first cover plate 110 and a first circuit board 120, and the touch panel 1 where the first touch component 100 is located can be directly assembled on the electronic device without the need for an additional cover plate. Optionally, as shown in Figures 1 and 2, the first cover plate 110 and the first circuit board 120 can be connected to each other by a connector, such as an adhesive layer 111.
[0075] The first cover plate 110 is located on the outer surface of the touch panel 1 and is a substantially planar sheet of rigid material. Its upper surface is configured to contact one or more user objects, such as fingers or a stylus, when the touch panel 1 is operated. Therefore, the user can provide input by using the one or more user objects to click, slide, press, or otherwise apply force to the surface of the first cover plate 110.
[0076] It should be noted that, for ease of description, in this application, "up" and "down" refer to the direction toward and away from the user, respectively, rather than the absolute "opposite direction of gravity" and "direction of gravity." Therefore, the upper surface of the first cover plate 110 is the surface facing the user, and conversely, the lower surface of the first cover plate 110 is the surface facing away from the user. Similar to the first cover plate 110, the "up" and "down" directions of other components of the touchpad 1 can also be understood as the direction toward and away from the user.
[0077] The first circuit board 120 can specifically be a printed circuit board (PCB) or a flexible printed circuit (FPC) with reinforcement. A printed circuit board assembly (PCBA) can be formed by mounting components on the first circuit board 120 using surface mount technology (SMT) or configuring a touch sensor, a first travel switch 101, a connector and other electronic components using a dual in-line package (DIP). The PCBA can be used to implement touch sensing and press detection functions of the touchpad. Optionally, the PCBA can implement communication functions through a connector and a laptop keyboard or a leather case keyboard. Optionally, the touch sensor in the PCBA is specifically a touch sensing layer built into the first circuit board 120.
[0078] The first travel switch 101 may include an elastic structure protruding from the lower surface of the first circuit board 120 and a conduction point arranged on the lower surface of the first circuit board 120. In conjunction with the first travel switch 101, a first contact 501 is provided on the surface of the fixed platform 500 facing the first circuit board 120. The first contact 501 may be a protruding structure in the fixed platform 500 protruding toward the first circuit board 120. When the user does not press on the first cover plate 110, the elastic structure may contact or separate from the first contact 501. At this time, the state of the elastic structure is its initial state or default state. When the elastic structure and the first contact 501 are separated from each other, the initial state of the elastic structure is an undeformed state. When the elastic structure and the first contact 501 are in contact with each other, the initial state of the elastic structure may be a slightly deformed state or an undeformed state.
[0079] When a user's finger presses on the first cover plate 110, the elastic structure in the first travel switch 101 can move in the pressing direction and contact the first contact 501, causing the elastic structure to deform. The deformed elastic structure then contacts the conduction point on the first circuit board 120, turning the first travel switch 101 on. After the user's finger removes the pressing force on the first cover plate 110, the deformed elastic structure can return to its initial state, freeing it from contact with the conduction point on the first circuit board 120, thereby turning the first travel switch 101 off. In the first travel switch 101, the movement distance of the elastic structure in the pressing direction can be understood as the pressing distance of the travel switch 101. As one possible embodiment, the elastic structure in the first travel switch 101 can be a pot, and the first travel switch can be understood as a dome key. Alternatively, in some alternative embodiments, the first travel switch 101 can be a switch in addition to a dome key. The specific implementation of the first travel switch 101 is not limited in this embodiment.
[0080] 1 and 2 , the first travel switch 101 can be fixed to the center area of the lower surface of the first circuit board 120 by bonding or SMT. Alternatively, in other embodiments, the first travel switch 101 can be located at other locations on the lower surface of the first circuit board 120 as needed.
[0081] Furthermore, the touch panel 1 includes an FPC600, as shown in Figures 1 and 2, which connects the first circuit board 120 and the second circuit board 320. One end of the FPC600 is arranged on the lower surface of the first circuit board 120, and the other end of the FPC600 is arranged on the lower surface of the second circuit board 320. Therefore, through the FPC600, the electrical signals of the first circuit board 120 and the second circuit board 320 can be transmitted to each other, thereby realizing touch sensing and press detection functions while saving manufacturing costs and reducing the configuration complexity of touch sensing and press detection.
[0082] The FPC 600 can be directly mounted on the lower surfaces of the first circuit board 120 and the second circuit board 320 by soldering, SMT, or the like, thereby connecting the FPC 600 to the first circuit board 120 and the second circuit board 320. Alternatively, connectors can be mounted on the lower surfaces of the first circuit board 120 and the second circuit board 320, respectively, so that the ends of the FPC 600 are respectively inserted into the connectors on the lower surfaces of the first circuit board 120 and the second circuit board 320, thereby connecting the FPC 600 to the first circuit board 120 and the second circuit board 320. This application does not limit the connection method of the FPC 600.
[0083] Specifically, in order to reduce the number of components assembled on the circuit board and reduce the configuration complexity of touch sensing, a touch controller 121 can be configured only on the lower surface of the first circuit board 120. When the user presses the area above the second circuit board 320 of the touch pad 1, that is, the second cover 310 in Figure 1, the second circuit board 320 will transmit the corresponding electrical signal generated by the user's press to the first circuit board 120 through the FPC600, and then transmit it to the touch controller 121 configured on the lower surface of the first circuit board 120. The touch controller 121 processes the corresponding electrical signal generated by the second circuit board 320 to achieve touch detection.
[0084] The first touch module 10 and the second touch module 20 are electrically connected via FPC 600, allowing the first touch module 10 and the second touch module 20 to independently receive user pressure while also conducting electrical signals generated by the user pressure between the first touch module 10 and the second touch module 20. This enables touch detection on a large-scale touch panel, saving manufacturing costs and reducing the complexity of touch sensing and pressure detection configurations. The touch panel 1 also includes a first support assembly 200 for supporting the first touch assembly 100.
[0085] Specifically, in the first support assembly 200, the first main support member 210 can be a frame-shaped support member, which is disposed at the edge of the lower surface of the first circuit board 120. Optionally, the first main support member 210 can be connected to the edge of the lower surface of the first circuit board 120 through a connector such as an adhesive layer 201.
[0086] The shape of the first main support member 210 can be adapted to the shape of the first circuit board 120. For example, if the first circuit board 120 is a rectangular circuit board, the first main support member 210 can be a rectangular frame. In addition, the first main support member 210 must have a certain degree of rigidity and strength to ensure reliable support for the first touch assembly 100 and enhance the overall strength of the touch panel 1.
[0087] Furthermore, below the first support assembly 200 is a fixed platform 500, which is a fixed component. The touchpad 1 can be mounted on the electronic device via this fixed platform 500, and the fixed platform 500 can be stably fixed in the electronic device. The fixed platform 500 also needs to have a certain degree of rigidity and strength to ensure reliable support for the first touch assembly 100 and the first support assembly 200, and to enhance the overall strength of the touchpad 1.
[0088] Optionally, in some embodiments, the fixing platform 500 is provided with a mounting member, and the mounting member is used to mount the fixing platform 500 on the electronic device where the touch panel 1 is located.
[0089] As an example, mounting elements include, but are not limited to, screw holes and screws, clips, adhesive layers, and other components used to achieve connection and installation. Specifically, if the mounting elements include screw holes and screws, the edge areas of the fixing platform 500 can be provided with screw holes, and the screws can pass through the screw holes to secure the fixing platform 500 to the electronic device.
[0090] If the electronic device containing the touchpad 1 is a laptop computer, the mounting member can be used to mount the touchpad 1 in the laptop's C-shell, i.e., the laptop's keyboard-side housing. For example, the C-shell has a through-hole for accommodating the touchpad 1. The mounting member can attach the fixing platform 500 to the edge of the through-hole, so that the touchpad 1 is mounted and accommodated in the through-hole of the C-shell.
[0091] Through the technical solution of this embodiment, the touch panel 1 can be directly installed on the electronic device using the fixed platform 500. The overall installation method is easy to implement and has high reliability, which is conducive to improving the assembly efficiency of the touch panel 1 in the electronic device and also facilitates its disassembly and maintenance.
[0092] In the embodiment of the present application, the fixed platform 500 and the first main support member 210 can be connected to each other via a first elastic member 220 and a second elastic member 230. Specifically, the first elastic member 220 is connected between the first side 211 of the first main support member 210 and the fixed platform 500, and the second elastic member 230 is connected between the second side 212 of the second main support member 210 and the fixed platform 500. When a user presses on the first touch component 100, the first touch component 100 drives the first main support member 210 connected thereto to move in the pressing direction. The first elastic member 220 and the second elastic member 230 undergo elastic deformation under the action of the pressing force, and the first travel switch 101 in the first touch component 100 can contact the first contact point 501 on the fixed platform 500 to detect the user's press. After the user's pressing force is withdrawn, the first elastic member 220 and the second elastic member 230 can return to their original state. The two elastic members, the first main support member 210 and the fixing platform 500 can provide good support for the first touch component 100 .
[0093] In addition, the first elastic member 220 and the second elastic member 230 are symmetrically connected to the first main support member 210 along the plane where the first main support member 210 is located, so that the first elastic member 220 and the second elastic member 230 have good symmetry in the touch pad 1. The two can respectively adapt to the user's pressing in two symmetrical areas in the touch pad 1 to provide the user with balanced force feedback.
[0094] As shown in Figures 1 and 2, the touch panel 1 further includes a second touch assembly 300 and a second support assembly 400. The second support assembly 400 has the same structure and working principle as the first support assembly 200.
[0095] Among them, the second touch component 300 is used to receive user pressure, and a second travel switch 301 is provided on the lower surface of the second touch component 300, and the second touch component 300 may include a second circuit board 320, or the second touch component 300 may directly include a second cover plate 310 and a second circuit board 320. Optionally, the second cover plate 310 and the second circuit board 320 can be connected to each other through a connecting member, such as a glue layer 311.
[0096] The general structure and working principle of the second touch assembly 300 are the same as those of the first touch assembly 100 . For details, please refer to the relevant description of the first touch assembly 100 , which will not be repeated here for the sake of brevity.
[0097] The second main support member 410 is disposed at the edge of the lower surface of the second touch assembly 300. The second main support member 410 is frame-shaped and has a third side 411 and a fourth side 412 that oppose each other. The frame has a hollow area. The second support assembly 400 includes: a second main support member 410, a third elastic member 420, and a fourth elastic member 430. Optionally, the second main support member 410 can be connected to the edge of the lower surface of the second circuit board 320 via a connector, such as an adhesive layer 401.
[0098] The fixed platform 500 is arranged below the third elastic member 420 and the fourth elastic member 430. The third elastic member 420 is connected between the third side 411 of the second main support member 410 and the fixed platform 500. The fourth elastic member 430 is connected between the fourth side 412 of the second main support member 410 and the fixed platform 500. A second contact point 502 is provided on the surface of the fixed platform 500 facing the second touch component 300.
[0099] The general structure and working principle of the second main support member 400 are the same as those of the first main support member 200. For details, please refer to the relevant description of the first main support member 200. For the sake of brevity, they will not be repeated here.
[0100] Furthermore, as shown in FIG1 and FIG2 , the first elastic member 220 and the second elastic member 230 enclose a first window area 290, and the third elastic member 420 and the fourth elastic member 430 enclose a second window area 490. One end of the FPC 600 passes through the first window area 290 and the hollow area of the first main support member 210 to connect to the lower surface of the first circuit board 120, and the other end of the FPC 600 passes through the second window area 490 and the hollow area of the second main support member 410 to connect to the lower surface of the second circuit board 320. This connection method can save assembly space for the touch panel 1 and facilitate installation of the touch panel 1 in an electronic device.
[0101] Optionally, windows can be provided on the fixed platform 500 through which both ends of the FPC 600 can pass. Then, one end of the FPC 600 simultaneously passes through the first window area 290, the hollow area of the first main support member and the window of the fixed platform to be connected to the lower surface of the first circuit board 120, and the other end of the FPC 600 simultaneously passes through the second window area 490, the hollow area of the second main support member and the window of the fixed platform to be connected to the lower surface of the second circuit board 320.
[0102] In the description of Figures 1 and 2 above, the touchpad 1 includes a first cover plate 110 and a second cover plate 310, and a first gap exists between the first cover plate 110 and the second cover plate 310. Optionally, the first gap is less than or equal to 0.2 mm. The upper surfaces of the first cover plate 110 and the second cover plate 120 are approximately in the same plane, and the upper surfaces of the first cover plate 110 and the second cover plate 310 are configured to contact one or more user objects, such as fingers or styluses, when the touchpad 1 is operated. Therefore, the user can provide input by using the above one or more user objects to click, slide or press or otherwise apply force to the surface of the first cover plate 110 and / or the second cover plate 310. Since the first cover plate 110 and the second cover plate 310 are independently arranged and there is a first gap, the functional diversity of the touchpad 1 is increased. The user can press the first cover plate 110 and the second cover plate 310 separately to achieve different functions, thereby improving the user experience and increasing the playability of the touchpad. Furthermore, there is a second gap between the first circuit board 120 and the second circuit board 320 below the first cover plate 110 and the second cover plate 310. The second gap is larger than the first gap, preventing the user from moving the second circuit board in the pressing direction when pressing the first cover plate, or preventing the user from moving the first circuit board in the pressing direction when pressing the second cover plate, thereby ensuring the reliability and accuracy of the pressing and avoiding erroneous touch detection.
[0103] The first cover plate 110 and the second cover plate 310 have a certain degree of rigidity to support user pressure. Specifically, the first cover plate 110 and the second cover plate 120 can be made of a rigid material such as a polycarbonate (PC) sheet, a ceramic sheet, glass, or a Mylar sheet. Optionally, when the first cover plate 110 and the second cover plate 120 are specifically made of glass, a Mylar sheet can be placed over them to provide shielding and beautify the touch panel. This embodiment of the application does not limit the specific structure and material of the first cover plate 110 and the second cover plate 310.
[0104] Optionally, in some embodiments, to optimize the appearance of the touchpad 1 and reduce the complexity of the assembly module, the first cover plate 110 and the second cover plate 310 may also form an integral cover plate, as shown by the third cover plate 130 in FIG3 . That is, the touchpad 1 includes only one cover plate, namely the third cover plate 130. The third cover plate 130 is disposed above the first circuit board 120 and the second circuit board 320 and is connected to the first circuit board 120 and the second circuit board 320 via a connector, such as an adhesive layer. The third cover plate 130 can perform the functions of both the first cover plate 110 and the second cover plate 120 described above, and for the sake of brevity, it will not be further described here. The third cover plate 130 also has a certain rigidity to support user pressing, and can be specifically made of rigid materials such as polycarbonate (PC) sheet, ceramic sheet, glass, Mylar sheet, etc. Optionally, when the third cover plate 130 is specifically glass, a Mylar sheet can be covered on top of it to block it and beautify the touch panel. The embodiment of the present application does not limit the specific structure and material of the third cover plate 130.
[0105] In addition, the first support assembly 200 includes a first elastic member 220 and a second elastic member 230, and the second support assembly 400 includes a third elastic member 420 and a fourth elastic member 440. The second elastic member 230 and the third elastic member 420 are independent of each other, which facilitates module assembly and reduces module assembly complexity.
[0106] Alternatively, in some embodiments, as shown in FIG3 , to further reduce module costs, the second elastic member 230 and the third elastic member 420 may form an integral elastic member, as shown by the fifth elastic member 270 in FIG3 . The fifth elastic member 270 is connected between the second side 212 of the first main support member 210 and the fixed platform 500, and is also connected between the third side 411 of the second main support member 410 and the fixed platform 500. The fifth elastic member 270 can perform both the functions of the second elastic member 230 and the functions of the third elastic member 420. The different composition structures of the above elastic members all fall within the scope of protection of this application.
[0107] In summary, through the technical solution of the embodiment of the present application, the touch panel 1 composed of the first touch module 10 and the second touch module 20 can provide a smaller press trigger stroke while maintaining a large size, achieve full-area press, provide balanced force feedback to the user, enhance the user's full-area press tactile experience, and save manufacturing costs and reduce the configuration complexity of touch sensing and press detection.
[0108] In the embodiments shown in Figures 1 and 2 or 3 above, although the touchpad 1 can detect a press by a user pressing any position of the first touch component 100 and / or the second touch component 300, if the user presses one end of the first touch component 100 and / or the second touch component 300, the other end may tilt without restraint. In this case, the tilted first touch component 100 and / or the second touch component 300 may affect the press travel of the first travel switch 101 and / or the second travel switch 301, thereby affecting the contact between the first travel switch 101 and the first contact 501, and / or the second travel switch 301 and the second contact 502, thereby affecting the press detection performance of the touchpad 1.
[0109] In view of this, based on the embodiments shown in FIG. 1 and FIG. 2 or FIG. 3 , FIG. 4 and FIG. 5 respectively show a schematic exploded view and a schematic cross-sectional view of another touch panel 1 provided in an embodiment of the present application.
[0110] As shown in Figures 4 and 5, the first support assembly 200 further includes a first attachment member 240 and a second attachment member 250. Correspondingly, the second support assembly 400 further includes a third attachment member 440 and a fourth attachment member 450. The first attachment member 240 is attached to the lower surface of the first elastic member 220, and the second attachment member 250 is attached to the lower surface of the second elastic member 230. The third attachment member 440 is attached to the lower surface of the third elastic member 420, and the fourth attachment member 450 is attached to the lower surface of the fourth elastic member 430.
[0111] Optionally, in some embodiments, the first attachment member 240 may be attached to the upper surface of the first elastic member 220, and the second attachment member 250 may be attached to the upper surface of the second elastic member 230. The third attachment member 440 may be attached to the upper surface of the third elastic member 420, and the fourth attachment member 450 may be attached to the upper surface of the fourth elastic member 430. The embodiments of the present application are described using the structures shown in Figures 4 and 5 as examples.
[0112] Figure 6 shows a schematic enlarged view of the first elastic member 220, the second elastic member 230, the first attachment member 240, and the second attachment member 250 in Figures 4 and 5. Figure 7a shows a schematic bottom view of the first elastic member 220, the second elastic member 230, the first attachment member 240, and the second attachment member 250 after assembly, and Figure 7b is an enlarged schematic view of portion A in Figure 7a.
[0113] 6 , 7 a and 7 b , the first attachment member 240 has a first protrusion 2401 extending below the second elastic member 230 , and the second attachment member 250 has a second protrusion 2501 extending below the first elastic member 220 .
[0114] Optionally, the first side of the first attachment 240 and the first elastic member 220 is a side close to the first edge 211 of the first main support member 210, wherein the first side of the first elastic member 220 is connected to the first edge 211 of the first main support member 210. Conversely, the second side of the first attachment 240 and the first elastic member 220 is a side away from the first edge 211 of the first main support member 210.
[0115] Similarly, the first side of the second attachment 250 and the second elastic member 230 is a side close to the second edge 212 of the first main support member 210, wherein the first side of the second elastic member 220 is connected to the second edge 212 of the first main support member 210. Conversely, the second side of the second attachment 250 and the second elastic member 230 is a side away from the second edge 212 of the first main support member 210.
[0116] The first elastic member 220 is provided with an elastic connector between the first side and the second side thereof, connected to the fixed platform 500. The second elastic member 230 is provided with an elastic connector between the first side and the second side thereof, connected to the fixed platform 500. When a user presses on the first touch component 100, the elastic connector between the first side and the second side of the first elastic member 220 and the fixed platform 500 serves as a force fulcrum for the first elastic member 220, and the elastic connector between the first side and the second side of the second elastic member 230 and the fixed platform 500 serves as a force fulcrum for the second elastic member 230.
[0117] A first protrusion 2401 is provided on the second side of the first attachment member 240, and a second protrusion 2501 is provided on the second side of the second attachment member 250. In this case, the first protrusion 2401 extends below the second side of the second elastic member 230, and the second protrusion 2501 also extends below the second side of the first elastic member 220.
[0118] When a user presses on an area of the first touch component 100 near the first side 211 of the first main support member 210, the first side of the first elastic member 220 moves downward, and correspondingly, the second side of the first elastic member 220 moves upward. At this point, the second side of the first elastic member 220 acts on the second protrusion 2501 of the second attachment member 250 located below it, causing the second attachment member 250 to move the second side of the second elastic member 230 upward, while the second attachment member 250 and the first side of the second elastic member 230 move downward. As the first side of the second elastic member 230 moves downward, the second side 212 of the first main support member 210, which is connected to the first side of the second elastic member 230, also moves the area of the first touch component 100 near the second side 212 downward. Therefore, when the user presses the area of the first touch component 100 close to the first side 211 of the first main support member 210, the area of the first touch component 100 close to the second side 212 of the first main support member 210 will not be lifted, thereby further improving the press detection performance of the touch panel 1.
[0119] Similarly, when a user presses on an area of the first touch component 100 near the second side 212 of the first main support member 210, the first side of the second elastic member 230 moves downward, and correspondingly, the second side of the second elastic member 230 moves upward. At this point, the second side of the second elastic member 230 acts on the first protrusion 2401 of the first attachment member 240 located below it, causing the first attachment member 240 to move the second side of the first elastic member 220 upward, and the first attachment member 240 and the first side of the first elastic member 220 to move downward. When the first side of the first elastic member 220 moves downward, the first side 211 of the first main support member 210, which is connected to the first side of the first elastic member 220, also moves the area of the first touch component 100 near the first side 211 of the first main support member 210 downward. Therefore, when the user presses the area of the first touch component 100 close to the second side 212 of the first main support member 210, the area of the first touch component 100 close to the first side 211 of the first main support member 210 will not be lifted, thereby further improving the press detection performance of the touch panel 1.
[0120] Similarly, the third attachment 440 in Figures 4 and 5 has the same structure and working principle as the first attachment 240, and the fourth attachment 450 has the same structure and working principle as the second attachment 250. The third attachment 440 is attached to the lower surface of the third elastic member 420, and the third attachment 440 has a third protrusion extending to the bottom of the fourth elastic member 430. The fourth attachment 450 is attached to the lower surface of the fourth elastic member 430, and the fourth attachment 450 has a fourth protrusion located below the third elastic member 430. The first side of the third elastic member 420 is connected to the third edge 411 of the second main support member 410, and a third protrusion is provided below the second side of the third elastic member 420, wherein the second side of the third elastic member 420 is opposite to the first side of the third elastic member 420, and the third elastic member 420 is provided with an elastic connecting member connected to the fixed platform 500 between the first side and the second side, and the first side of the fourth elastic member 430 is connected to the fourth edge 412 of the second main support member 410, and a fourth protrusion is provided below the second side of the fourth elastic member 430, wherein the second side of the fourth elastic member 430 is opposite to the first side of the fourth elastic member 430, and the fourth elastic member 430 is provided with an elastic connecting member connected to the fixed platform 500 between the first side and the second side. For details, please refer to the relevant description of the first attachment 240 and the second attachment 250 mentioned above. For the sake of brevity, it will not be repeated here.
[0121] In summary, through the technical solutions of the embodiments of the present application, when a user presses on one end of the first touch component 100 and / or the second touch component 300, the other end will not tilt due to the combined action of the elastic member and the connector, thereby further improving the press detection performance of the touchpad 1. For example, when a user presses on the end region of the first touch component 100 close to the first side 211 of the first main support member 210, or presses on the end region of the first touch component 100 close to the second side 212 of the first main support member 210, the other end of the first touch component 100 will not tilt due to the combined action of the elastic member and the connector, thereby further improving the press detection performance of the touchpad 1.
[0122] In addition to improving the press detection performance of the touch panel 1, the first and second attachments 240 and 250, as well as the third and fourth attachments 440 and 450, can also strengthen the touch panel 1. Furthermore, the first attachment 240, when attached to the first elastic member 220, can also reinforce the first elastic member 220; the second attachment 250, when attached to the second elastic member 230, can also reinforce the second elastic member 230; the third attachment 440, when attached to the third elastic member 420, can also reinforce the third elastic member 420; and the fourth attachment 450, when attached to the fourth elastic member 430, can also reinforce the fourth elastic member 430. Therefore, the attachments not only ensure elastic deformation of the elastic members, but also guarantee their reliability and service life.
[0123] Alternatively, as shown in Figures 2, 4, and 5, the first elastic member 220, the second elastic member 230, the third elastic member 420, and the fourth elastic member 430 may have the same shape, and correspondingly, the first attachment member 240, the second attachment member 250, the third attachment member 440, and the fourth attachment member 450 may have similar or identical shapes. The first attachment member 240 and the second attachment member 250 may be accommodated in the hollow area of the frame-shaped first main support member 210, and the third attachment member 440 and the fourth attachment member 450 may be accommodated in the hollow area of the frame-shaped second main support member 410.
[0124] In some embodiments, the first touch assembly 100 and the second touch assembly 300 are both rectangular touch assemblies. Referring back to FIG6 , the first elastic member 220 includes two first elastic arms 221 parallel to the long side of the rectangular touch assembly and a first middle portion 222 connecting the two first elastic arms 221. The second elastic member 230 includes two second elastic arms 231 parallel to the long side of the rectangular touch assembly and a second middle portion 232 connecting the two second elastic arms 231. In the direction parallel to the long side of the rectangular touch assembly, the two first elastic arms 221 and the two second elastic arms 231 correspond to each other and have a gap therebetween.
[0125] Through the technical solution of this embodiment, the two first elastic arms 221 of the first elastic member 220 and the two second elastic arms 231 of the second elastic member 230 are parallel to the long side of the rectangular touch assembly. This allows the first elastic member 220 and the second elastic member 230 to better ensure the user's pressing feel in the long side direction of the first touch assembly 100 and ensure that the touchpad 1 detects the user's pressing. In addition, the two first elastic arms 221 and the two second elastic arms 231 can be distributed along the short side of the rectangular touch assembly. Correspondingly, the two first elastic arms 221 distributed along the short side can be connected by a first middle portion 222 distributed along the long side, and the two second elastic arms 231 distributed along the short side can be connected by a second middle portion 232 distributed along the long side. This also ensures that the user can press in the short side direction of the first touch assembly 100.
[0126] Optionally, as shown in Figure 2, the first middle portion 222 and the second middle portion 232 can be solid portions, that is, no through holes are provided therein, so as to ensure the reliability of the first elastic member 220 and the second elastic member 230, and the setting position of the solid portion needs to avoid other components in the touch panel 1, such as components on the lower surface of the first circuit board 120.
[0127] Alternatively, in other alternative embodiments, through holes may be formed in the first middle portion 222 and the second middle portion 232 to reduce the overall weight of the first elastic member 220 and the second elastic member 230, and to provide accommodation space for other devices in the touch panel 1, such as providing accommodation space for components on the lower surface of the circuit board 120.
[0128] Optionally, in the first elastic member 220, at least one first elastic connector 2221 is provided on the side of the first middle portion 222 facing the first side 211 of the first main support member 210. The first elastic member 220 is connected to the first side 211 of the first main support member 210 via the at least one first elastic connector 2221. Correspondingly, at least one second elastic connector 2222 is provided on the other side of the first middle portion 222 away from the first side 211 of the first main support member 210. The first elastic member 220 is connected to the fixed platform 500 via the at least one second elastic connector 2222. As an example, in the embodiment shown in FIG. 6 , two first elastic connectors 2221 and two second elastic connectors 2222 are provided on either side of the first middle portion 222, respectively.
[0129] The at least one second elastic connection member 2222 connected to the fixed platform 500 is disposed between the two first elastic arms 221 . When a user presses the first touch component 100 , the at least one second elastic connection member 2222 can serve as a force fulcrum for the first elastic member 220 .
[0130] In some embodiments, the at least one first elastic connector 2221 and the at least one second elastic connector 2222 may be integrally formed with the first middle portion 222. In this case, the at least one first elastic connector 2221 and the at least one second elastic connector 2222 may be understood as a cantilever beam structure provided on the first middle portion 222. Alternatively, in other embodiments, the at least one first elastic connector 2221 and the at least one second elastic connector 2222 may be separate structures from the first middle portion 222. The at least one first elastic connector 2221 and the at least one second elastic connector 2222 are connected to the first middle portion 222 by adhesive, welding, or other connection methods.
[0131] It is understood that after the first elastic member 220 is connected to the first side 211 of the first main support member 210 via at least one first elastic connector 2221, the first elastic connector 2221, except for the two end regions, has a middle region thereof in a suspended state, thereby ensuring the elastic connection between the first elastic member 220 and the first side 211 of the first main support member 210. Furthermore, after the first elastic member 220 is connected to the fixed platform 500 via at least one second elastic connector 2222, the second elastic connector 2222, except for the two end regions, has a middle region thereof in a suspended state, thereby ensuring the elastic connection between the first elastic member 220 and the fixed platform 500.
[0132] Similar to the first elastic member 220 described above, in the second elastic member 230, at least one third elastic connector 2321 is provided on the side of the second intermediate portion 232 facing the second side 212 of the main support member 210. The second elastic member 230 is connected to the second side 212 of the main support member 210 via the at least one third elastic connector 2321. At least one fourth elastic connector 2322 is provided on the other side of the second intermediate portion 232, away from the second side 212 of the main support member 210. The second elastic member 230 is connected to the fixed platform 500 via the at least one fourth elastic connector 2322. As an example, in the embodiment shown in FIG6 , two third elastic connectors 2321 and two fourth elastic connectors 2322 are provided on either side of the second intermediate portion 232, respectively. Specifically, the design of the third elastic connector 2321 and the fourth elastic connector 2322 in the second elastic member 230 can be found in the above description of the first elastic connector 2221 and the second elastic connector 2222, and will not be further elaborated here.
[0133] Through the technical solution of the embodiments of the present application, elastic connectors are provided on both sides of the middle portion of each elastic member to achieve elastic connection between the first and second main support members and the fixed platform 500. This allows the first and second elastic members 220 and 230, and / or the third and fourth elastic members 420 and 430 to deform when a user presses the first touch component 100 and / or the second touch component 300. This integrated approach is easy to implement, and the connection area between the elastic member, the main support member, and the fixed platform is small, effectively ensuring the elastic deformation of the elastic member, thereby ensuring the pressing performance of the touchpad 1.
[0134] Corresponding to the first elastic member 220 and the second elastic member 230 described above, as further shown in FIG6 , the first attachment member 240 includes two first connecting arms 241 attached to the lower surfaces of the two first elastic arms 221, and the second attachment member 250 includes two second connecting arms 251 attached to the lower surfaces of the two second elastic arms 231. The two first connecting arms 241 correspond to the two second connecting arms 251 with a gap therebetween. The two first connecting arms 241 have one end facing the two second connecting arms 251 provided with a first protrusion 2401 located below the two second elastic arms 231, and the two second connecting arms 251 have one end facing the two first connecting arms 241 provided with a second protrusion 2501 located below the two first elastic arms 221.
[0135] Specifically, in this embodiment, the two first connecting arms 241 of the first attachment member 240 are attached to the two first elastic arms 221 on the lower surface of the first elastic member 220 to support and reinforce the two first elastic arms 221. Similarly, the two first connecting arms 251 of the second attachment member 250 are attached to the two second elastic arms 231 on the lower surface of the second elastic member 230 to support and reinforce the two second elastic arms 231.
[0136] Optionally, the first attachment member 240 and the second attachment member 250 may be attached to the lower surfaces of the first elastic member 220 and the second elastic member 230 respectively by adhesion, welding, stamping, etc.
[0137] Two first protrusions 2401 are provided on one end of the two first connecting arms 241 facing the two second connecting arms 251. These first protrusions 2401 are located below the two second elastic arms 231. When a user presses on the touch control assembly 100, these first protrusions 2401 act on the ends of the two second elastic arms 231. Two second protrusions 2501 are provided on one end of the two second connecting arms 251 facing the two first connecting arms 241. These second protrusions 2501 are located below the two first elastic arms 221. When a user presses on the touch control assembly 100, these second protrusions 2501 act on the ends of the two first elastic arms 221.
[0138] It is understood that the first attachment member 240 further includes a middle portion connecting the two first connecting arms 241, and the second attachment member 250 also includes a middle portion connecting the two second connecting arms 251. The middle portion of the first attachment member 240 can be attached to the first middle portion 222 of the first elastic member 220, and the middle portion of the second attachment member 250 can be attached to the second middle portion 232 of the second elastic member 230.
[0139] The middle portion of the first attachment 240 and the middle portion of the second attachment 250 can also be solid or formed with a through hole. The embodiment of the present application does not limit the specific shape of the middle portion of the first attachment 240 and the middle portion of the second attachment 250.
[0140] 6, 7a and 7b, the first protrusions 2401 of the two first connecting arms 241 correspond to the recesses for accommodating the second protrusions 2501 of the two second connecting arms 251. The second protrusions 2501 of the two second connecting arms 251 correspond to the recesses for accommodating the first protrusions 2401 of the two first connecting arms 241.
[0141] Through the technical solution of this embodiment, the first protrusion 2401 and the second protrusion 2501 between the two first connecting arms 241 and the two second connecting arms 251 can be adapted to each other without causing additional space waste, and more reliably ensuring the press detection performance of the touch panel 1.
[0142] Similar to the first elastic member 220 and the second elastic member 230 described above, the third elastic member 420 has two third elastic arms parallel to the long side direction of the second touch component 300 and a third middle portion connecting the two third elastic arms, and the fourth elastic member 430 has two fourth elastic arms parallel to the long side direction of the second touch component 300 and a fourth middle portion connecting the two fourth elastic arms. At least one fifth elastic connector is provided on the side of the third middle portion facing the third side 411 of the second main support member 300, and the third elastic member 420 is connected to the third side 411 of the second main support member 300 through at least one fifth elastic connector. At least one sixth elastic connector is provided on the other side of the third middle portion away from the third side 411 of the second main support member 300, and the third elastic member 420 is connected to the fixed platform 500 through at least one sixth elastic connector. At least one seventh elastic connector is provided on the side of the fourth middle portion facing the fourth side 412 of the second main support member 300, and the fourth elastic member 430 is connected to the fourth side 412 of the second main support member 300 through at least one seventh elastic connector. The fourth middle portion is away from the second main support member. At least one eighth elastic connecting member is provided on the other side of the fourth side 412 of 300, and the fourth elastic member 430 is connected to the fixed platform 500 through at least one eighth elastic connecting member; similar to the above-mentioned first attachment 240 and second attachment 250, the third attachment 440 has two third connecting arms attached to the lower surfaces of the two third elastic arms, and the fourth attachment 450 has two fourth connecting arms attached to the lower surfaces of the two fourth elastic arms, the two third connecting arms correspond to the two fourth connecting arms and have a gap, and the two third connecting arms are provided with a third protrusion located below the two fourth elastic arms at one end facing the two fourth connecting arms, and the two fourth connecting arms are provided with a fourth protrusion located below the two third elastic arms at one end facing the two third connecting arms.
[0143] Specifically, the related designs of the third elastic member 420 and the fourth elastic member 430 and the third attachment member 440 and the fourth attachment member 450 can refer to the above description of the first elastic member 220 and the second elastic member 230, and will not be elaborated here.
[0144] Optionally, in other alternative embodiments, in order to further reduce module costs and simplify the assembly process, the middle portion of the second elastic member 230 and the middle portion of the third elastic member 420 can be connected to form an integral elastic member, as shown in the fifth elastic member 270 in Figure 3. The fifth elastic member 270 can realize both the functions of the above-mentioned second elastic member 230 and the functions of the above-mentioned third elastic member 420. For the sake of brevity, they will not be repeated here.
[0145] In some embodiments, at least one component of the first support assembly 200 and / or the second support assembly 400 or the fixed platform 500 is provided with a pressure point groove, and the pressure point groove can be used to control the flatness of the at least one component.
[0146] As an example, the first main support member 210, the first elastic member 220, the second elastic member 230, the first attachment member 240, and the second attachment member 250 in the first support assembly 200 are all provided with pressure point grooves. The pressure point grooves can be provided on both the upper and lower surfaces of each component to adjust the flatness of each component.
[0147] Specifically, excessive flatness in any component of the first support assembly 200 can lead to poor consistency in the pressing force applied to the touchpad 1. This means that pressing at different locations on the touchpad 1 requires different forces, and the pressing force fluctuates significantly. Furthermore, due to the high flatness, the pressing stroke also needs to be considered, resulting in a longer pressing stroke, which in turn affects the user experience. Therefore, designing a flatness control system using pressure point grooves can further optimize the performance parameters of the touchpad 1 and enhance the user experience.
[0148] In some embodiments, the pressure point grooves can be square grooves with a side length of 0.15 mm. Alternatively, the pressure point grooves can be circular or other polygonal grooves, and their depths can vary on the first main support member 210, the fixed platform 500, the elastic members 220, 230, and the connecting members 240, 250. As an example, the depth of the pressure point grooves on the first main support member 210 can be 0.06 mm to 1 mm, used to control the flatness of the first main support member 210 to be less than 0.15 mm. The depth of the pressure point grooves on the fixed platform 500 can be 0.04 mm to 0.08 mm, allowing the user to control the flatness of the fixed platform 500 to be less than 0.05 mm. The depth of the pressure point grooves on the first and second elastic members 220, 230 can be 0.02 mm to 0.05 mm. The depth of the pressure point grooves on the first and second attachment members 240, 250 can be 0.04 mm to 0.08 mm.
[0149] In another alternative embodiment, pressure point grooves may be provided on both the upper and lower surfaces of two components as a whole to control the overall flatness of the two components. As an example, pressure point grooves are provided on both the upper and lower surfaces of the first main support member 210 and the fixed platform 500, while pressure point grooves are provided on only one side of the first elastic member 220, the second elastic member 230, the first attachment member 240, and the second attachment member 250. That is, the contact surface of the first elastic member 220 and the first attachment member 240 does not have a pressure point groove, and the contact surface of the second elastic member 230 and the second attachment member 250 does not have a pressure point groove.
[0150] In some possible implementations, as shown in FIG. 1 to FIG. 5 , the projection of the fixing platform 500 on the plane where the first touch component 100 and the second touch component 300 are located exceeds the first touch component 100 and the second touch component 300 .
[0151] Specifically, the components in the first touch component 100 and the second touch component 300 are plate-shaped members. As shown in Figures 1, 2, 4 and 5, the plane where the first touch component 100 and the second touch component 300 are located can be the plane where the first cover plate 110 and the second cover plate 310 in the first touch component 100 and the second touch component 300 are located, or it can also be the plane where the first circuit board 120 and the second circuit board 320 are located; as shown in Figure 3, the plane where the first touch component 100 and the second touch component 300 are located can be the plane where the third cover plate 130 is located, or it can also be the plane where the first circuit board 120 and the second circuit board 320 are located.
[0152] As shown in Figures 1, 2, 4 and 5, the projection of the fixing platform 500 on the plane where the first cover plate 110 and the second cover plate 310 are located may exceed the first cover plate 110 and the second cover plate 310, and the projection of the fixing platform 500 on the plane where the first circuit board 120 and the second circuit board 320 are located may also exceed the first circuit board 120 and the second circuit board 320, or, as shown in Figure 3, the projection of the fixing platform 500 on the plane where the third cover plate 130 is located may exceed the third cover plate 130, and the projection of the fixing platform 500 on the plane where the first circuit board 120 and the second circuit board 320 are located may also exceed the first circuit board 120 and the second circuit board 320.
[0153] That is, in this embodiment, in a direction parallel to the plane where the first touch component 100 and the second touch component 300 are located, the fixing platform 500 has a portion that exceeds the first touch component 100 and the second touch component 300. Therefore, the fixing platform 500 can have a larger area, thereby providing good support and protection for the first touch component 100 and the second touch component 300, thereby improving the overall stability of the touch panel 1.
[0154] In some embodiments, the first touch component 100 and the second touch component 300 are rectangular components. In this case, in the length direction and / or width direction of the first touch component 100 and the second touch component 300, the projection of the fixed platform 500 on the plane where the first touch component 100 and the second touch component 300 are located exceeds the first touch component 100 and the second touch component 300.
[0155] In some alternative embodiments, the projection of the fixed platform 500 on the plane where the first touch component 100 and the second touch component 300 are located may not exceed the first touch component 100 and the second touch component 300, and the embodiment of the present application does not limit this.
[0156] Figure 8 shows a schematic structural diagram of the fixing platform 500 in the above embodiment. As shown in Figure 8, in this embodiment of the present application, the center area of the fixing platform 500 is provided with a first protrusion 510 facing the first touch component 100 and a second protrusion 520 facing the second touch component 300. The first protrusion 510 is adapted to fit within the first window area 290 formed by the first elastic member 220 and the second elastic member 230 in Figures 2 and 4, and the second protrusion 520 is adapted to fit within the second window area 490 formed by the third elastic member 420 and the fourth elastic member 430. The first contact 501 is located in the center area of the first protrusion 510, and the second contact 502 is located in the center area of the second protrusion 520.
[0157] Optionally, as shown in Figure 8, the first raised portion 510 and the second raised portion 520 can both be "I"-shaped raised portions. In some alternative embodiments, the first raised portion 510 and the second raised portion 520 can also be raised portions of any shape such as a rectangle. The embodiment of the present application does not limit the specific shapes of the first raised portion 510 and the second raised portion 520.
[0158] Taking the first raised portion 510 as an example to illustrate the working principle and connection relationship of the raised portion, the first contact 501 can be located at a raised point in the center area of the first raised portion 510. The area and height of the first contact 501 can be designed accordingly based on the first travel switch 101 on the first circuit board 120, so that the first contact 501 can effectively contact and trigger the first travel switch 101. As shown in Figures 1 to 8, the first elastic member 220 and the second elastic member 230 can be connected to the first raised portion 510 to achieve mutual connection between the first elastic member 220 and the second elastic member 230 and the fixed platform 500. A gap is provided between the first elastic member 220 and the second elastic member 230 and the areas of the fixed platform 500 other than the first raised portion 510.
[0159] Specifically, at least one second elastic connector 2222 on the first middle portion 222 of the first elastic member 220 can be connected to the edge of the upper surface of the first protrusion 510 near the first middle portion 222, thereby connecting the first elastic member 220 to the fixed platform 500. At least one fourth elastic connector 2322 on the second middle portion 232 of the second elastic member 230 can be connected to the edge of the upper surface of the first protrusion 510 near the second middle portion 232, thereby connecting the second elastic member 230 to the fixed platform 500. It should be understood that the first elastic connector 2221 of the first elastic member 220 and the third elastic connector 2321 of the second elastic member 230 are only connected to the first main support member 210, and there is a gap between the first elastic connector 2221 and the second elastic connector 2321 and the fixed platform 500.
[0160] Likewise, the design and working principle of the second protrusion 520 of the fixing platform 500 may refer to the description of the first protrusion 510 , and will not be repeated here.
[0161] In the embodiment of the present application, a gap is provided between the first elastic member 220 and the second elastic member 230 and other areas of the fixed platform 500 except the first protrusion 510, and the gap can provide deformation space for the first elastic member 220 and the second elastic member 230. A gap is provided between the third elastic member 420 and the fourth elastic member 430 and other areas of the fixed platform 500 except the second protrusion 520, and the gap can provide deformation space for the third elastic member 420 and the fourth elastic member 430, so as to ensure that the first touch component 100 and / or the second touch component 300 can be displaced downward under the action of the user's pressure, thereby ensuring the press detection function of the touch pad 1.
[0162] Through the technical solution of this embodiment, the first protrusion 510 and the second protrusion 520 are provided in the central area of the fixed platform 500, which can facilitate the cooperation with the first elastic member 220 and the second elastic member 230, as well as the third elastic member 420 and the fourth elastic member 430 to realize the press detection function of the touch panel 1, and also facilitate reliable support and protection of the first touch component 100 and / or the second touch component 200.
[0163] Optionally, the first protrusion 510 and the second protrusion 520 in the above-mentioned application embodiment may be hollow protrusions or solid protrusions.
[0164] For example, in some embodiments, the first protrusion 510 and the second protrusion 520 can be hollow bosses formed by stamping the fixed platform 500, so that the first protrusion 510 and the second protrusion 520 can be easily formed in the fixed platform 500, and the overall weight of the fixed platform 500 is small and the cost is low.
[0165] Alternatively, in some possible embodiments, the first protrusion 510 and the second protrusion 520 may be solid protrusions. For example, a solid reinforcement portion may be provided on the upper surface of the fixing platform 500. This solid reinforcement portion not only forms a protrusion on the surface of the fixing platform 500, but also improves the connection strength between the fixing platform 500 and the elastic member. This solid reinforcement portion may be connected to the fixing platform 500 by various means, such as adhesive layer or welding, to form the first protrusion 510 and the second protrusion 520.
[0166] In other alternative embodiments, the solid reinforcement portion may also be connected to the fixing platform 500 via a connector to form a first protruding portion 510 and a second protruding portion 520 .
[0167] In this embodiment, FIG9 shows a schematic exploded view of another fixed platform 500 provided in an embodiment of the present application.
[0168] As shown in Figure 9, the fixed platform 500 is a roughly plate-like structure, and a reinforcement portion can be provided on its upper surface to form a first protrusion 510 and a second protrusion 520. As an example, the reinforcement portion in Figure 9 is in the shape of an "I". In other alternative embodiments, the reinforcement portion can also be adjusted to other shapes according to actual needs, and the embodiments of the present application do not make specific limitations on this.
[0169] The first protrusion 510 and the second protrusion 520 can be connected to the fixed platform via a connecting member 530, such as a screw. Specifically, the first protrusion 510 has at least one first connecting hole 511, and the second protrusion 520 has at least one second connecting hole 521. Correspondingly, the fixed platform 500 has at least one third connecting hole 503 corresponding to the at least one first connecting hole 511, and at least one fourth connecting hole 504 corresponding to the at least one second connecting hole 521. The connecting member 530 passes through the at least one third connecting hole 503 of the fixed platform 500 and the at least one first connecting hole 511 of the first protrusion 510, and also passes through the at least one fourth connecting hole 504 of the fixed platform 500 and the at least one second connecting hole 521 of the second protrusion 520, thereby locking and fixing the connecting member 530, thereby achieving the connection between the first protrusion 510 and the second protrusion 520 and the fixed platform.
[0170] In the embodiment shown in FIG9 , the first protrusion 510 and the second protrusion 520 can be connected to the fixed platform 500 via connectors 530 , respectively, which simplifies the assembly process and facilitates the disassembly of the fixed platform and the entire touch panel 1 , making it easier to maintain the production line.
[0171] As shown in Figures 8 and 9, one or more through holes can be provided in the fixed platform 500 provided in the embodiment of the present application. The through holes can be used to reduce the weight of the fixed platform 500 and can also be used to avoid other components in the electronic device where the touch panel 1 is located, thereby optimizing the overall performance of the touch panel 1 and the electronic device where it is located.
[0172] In the embodiment of the present application, the touchpad 1 can be mounted on an electronic device, such as a laptop computer's C-shaped case, via a fixing platform 500. Although the fixing platform 500 can indirectly support the first main support member 210, the second main support member 410, and the first and second touch components 100 and 300 via elastic connectors, the stability of the first and second main support members 210, 410, and the first and second touch components 100 and 300 is poor. Furthermore, due to manufacturing and assembly tolerances of the various components of the touchpad 1, the overall thickness of the touchpad 1 may vary. Consequently, after the touchpad 1 is mounted on an electronic device, the first and / or second touch components 100 and 300 may bulge or dent.
[0173] In view of this, in some embodiments of the present application, the first main support member 210 and the second main support member 410 may be further provided with a limiting portion on the basis of the rectangular frame shape, and the limiting portion is used to achieve the limitation of the main support members.
[0174] For example, as shown in Figure 10, the first side 211 of the first main support member 210 is provided with a first limiting portion 213, and the second side 412 of the second main support member 410 is provided with a second limiting portion 413. As an example, the first side 211 of the first main support member 210 is provided with two first limiting portions 213, and the second side 412 of the second main support member 410 is provided with two second limiting portions 413.
[0175] In conjunction with the first limiting portion 213 and the second limiting portion 413, a limiting hole can be provided in the electronic device where the touchpad 1 is located. For example, a limiting hole can be provided in the C-shell of a laptop computer. When the touchpad 1 is installed in the C-shell, the first limiting portion 213 on the first main support member 210 and the second limiting portion 413 on the second main support member 410 can be accommodated in the limiting hole to ensure that the relative positions of the first main support member 210 and the second main support member 410 in the C-shell are fixed, preventing the first touch assembly 100 and the second touch assembly 300 connected to the first main support member 210 and the second main support member 410 from protruding or sinking in the C-shell, resulting in a poor assembly effect of the touchpad 1 in the C-shell. In the case of a poor assembly effect, not only the aesthetic appearance of the touchpad 1 is affected, but also the user's experience of pressing the touchpad 1 is affected. Similar to the first main support member 210 and the second main support member 410 shown in Figure 10, the first main support member 210 and the second main support member 410 in the above embodiments can also be provided with a first limiting portion 213 and a second limiting portion 413 to limit the installation of the first main support member 210 and the second main support member 410 and the first touch component 100 and the second touch component 300 connected thereto in the electronic device.
[0176] In a specific implementation, the first limiting portion 213 can be a raised portion disposed on the periphery of the frame-shaped main body of the first main support member 210, and the second limiting portion 413 can be a raised portion disposed on the periphery of the frame-shaped main body of the second main support member 410. The shape, size, and number of the first limiting portion 213 and the second limiting portion 413 can be designed according to actual needs. The first limiting portion 213 and the second limiting portion 413 include, but are not limited to, block-shaped or plate-shaped structures.
[0177] Through the technical solution of this embodiment, the main support member can ensure the overall strength and structural stability of the touch panel 1. A limiting portion is set on the main support member to achieve the limitation of the main support member and the touch component connected thereto in the electronic device, thereby more reliably ensuring the installation and use of the touch panel 1 in the electronic device.
[0178] In addition to setting limiting holes in the C-shell of the electronic device to cooperate with the first limiting portion 213 of the first main support member 210 and the second limiting portion 413 of the second main support member 410, in other embodiments, limiting holes can also be set in the fixed platform 500 to limit the first main support member 210 and the second main support member 410.
[0179] As shown in FIG10 , the fixed platform 500 is similar in appearance to the fixed platform 500 in the above embodiment, with the difference being that the edge of the fixed platform 500 in the embodiment of the present application is bent upward to form a step structure 540, and the side wall of the step structure 540 is formed with a first limiting hole 541 and a second limiting hole 542. The first limiting hole 541 can cooperate with the first limiting portion 213 on the first main support member 210, so that the fixed platform 500 can limit the first main support member 210. The second limiting hole 542 can cooperate with the second limiting portion 413 on the second main support member 410, so that the fixed platform 500 can limit the second main support member 410.
[0180] Through the technical solution of this embodiment, the fixing platform 500 in the touchpad 1 can be used to limit the position of the first main support member 210 and the second main support member 410, without the need to provide additional limiting holes in the electronic device. While ensuring that the main support members and the touch control assembly connected thereto have a relatively stable structure, the installation of the touchpad 1 in the electronic device can be simplified, and its disassembly and maintenance can also be facilitated.
[0181] In some embodiments, in a direction perpendicular to the touch assembly 100 , the size of the first limiting hole 541 and the second limiting hole 542 is larger than the size of the first limiting portion 213 and the second limiting portion 413 .
[0182] For example, after the first limiting portion 213 is installed in the first limiting hole 541, the upper surface of the first limiting portion 213 can abut against the hole wall of the first limiting hole 541. When a user presses on the first touch assembly 100, the first limiting portion 213 can follow the first main support member 210 and move downward in the first limiting hole 541. The larger first limiting hole 541 provides a certain downward movement space for the first limiting portion 213 and limits the downward movement limit of the first limiting portion 213, thereby facilitating the user's pressing on the first touch assembly 100 and preventing the first touch assembly 100 from excessive downward movement and collapse, thereby improving the user's experience with the touchpad 1. Similarly, the design and working principles of the second limiting hole 542 and the second limiting portion 413 can refer to the relevant description of the first limiting hole 541 and the first limiting portion 213, and will not be repeated here.
[0183] Alternatively, in the embodiment shown in FIG10 , the fixed platform 500 may be a rectangular platform, with the edges of the two short sides of the fixed platform 500 bent upward to form two strip-shaped step structures 540. The two step structures 540 may correspond to the first side 211 of the first main support member 210 where the first position-limiting portion 213 is provided, and the second side 412 of the second main support member 410 where the second position-limiting portion 413 is provided, respectively.
[0184] Optionally, the step surface of the step structure 540 may be provided with mounting members, such as screw holes and screws, etc., for implementing the installation of the fixing platform 500 in the electronic device.
[0185] It is understandable that FIG10 is merely for illustration, and shows another fixing platform 500 having a step structure 540 based on the fixing platform 500 of the embodiment shown in FIG1 to FIG5 .
[0186] Optionally, in the above embodiments, the first contact 501 and the second contact 502 on the fixed platform 500 can be referred to as "conductive bases." As shown in Figures 2 to 4 above, the first contact 501 and the second contact 502 can be separate structures that are separated from the first protrusion 510 and the second protrusion, respectively. In some alternative embodiments, the first contact 501 and the second contact 502 can also be integral structures formed integrally with the first protrusion 510 and the second protrusion, respectively. For example, the first contact 501 can be a first boss formed integrally with the first protrusion 510 and protruding toward the first touch component 100, and the second contact 502 can be a second boss formed integrally with the second protrusion 520 and protruding toward the second touch component 300.
[0187] Specifically, if the first contact 501 and the second contact 502 can be a split structure separated from the first protrusion 510 and the second protrusion respectively, FIG11 shows a schematic diagram of an implementation method of the first contact 501 and the second contact 502 provided in an embodiment of the present application.
[0188] As shown in Figure 11, in an embodiment of the present application, the first contact 501 can be a first adjusting screw 5011 installed on the first protrusion 510, and the height of the first adjusting screw 5011 relative to the first protrusion 510 can be adjusted; the second contact 502 can be a second adjusting screw 5021 installed on the second protrusion 520, and the height of the second adjusting screw 5021 relative to the second protrusion 520 can be adjusted.
[0189] Optionally, in conjunction with the first adjusting screw 5011 and the second adjusting screw 5021, a first nut 5012 and a second nut 5022 may be provided on the fixed platform 500 to facilitate the installation of the first adjusting screw 5011 on the fixed platform 500 and the first protrusion 510, and to facilitate the installation of the second adjusting screw 5021 on the fixed platform 500 and the second protrusion 520.
[0190] The first adjusting screw 5011 passes through the first nut 5012 and protrudes from the first protrusion 510. The height at which the first adjusting screw 5011 protrudes from the first protrusion 510 can be adjusted, that is, the distance and interaction force between the first adjusting screw 5011 and the first limit switch 101 can be adjusted. Similarly, the second adjusting screw 5021 passes through the second nut 5022 and protrudes from the second protrusion 520. The height at which the second adjusting screw 5021 protrudes from the second protrusion 5021 can be adjusted, that is, the distance and interaction force between the second adjusting screw 5021 and the second limit switch 301 can be adjusted.
[0191] Through the technical solution of this embodiment, the first and second height-adjustable adjustment screws 5011 and 5021 can be better adapted to the first and second travel switches 101 and 301, respectively, making the first and second travel switches 101 and 301 more sensitive and accurate in sensing the pressing pressure. In addition, the first and second height-adjustable adjustment screws 5011 and 5021 can also tolerate deformation of the fixed platform 500 and thickness tolerances of the travel switches. In other words, even if the fixed platform 500 is deformed and / or the travel switches have thickness tolerances, the distance and interaction force between the adjustment screws and the travel switches can be adjusted by adjusting the screws to ensure good coordination between the travel switches and the adjustment screws, thereby ensuring the press detection performance of the touchpad 1.
[0192] FIG12 shows a schematic diagram of another implementation of the first contact 501 and the second contact 502 provided in an embodiment of the present application.
[0193] As shown in Figure 12, in the embodiment of the present application, the first contact 501 is specifically a first T-shaped screw 5013 provided on the first protrusion 510 and the fixed platform 500, the head of the first T-shaped screw 5013 faces the first limit switch 101, and the first T-shaped screw 5013 is fixed to the opening 512 in the first protrusion 510 through the adhesive layer 5014; the second contact 502 is specifically a second T-shaped screw 5023 provided on the second protrusion 520 and the fixed platform 500, the head of the second T-shaped screw 5023 faces the second limit switch 301, and the second T-shaped screw 5023 is fixed to the opening 522 in the second protrusion 520 through the adhesive layer 5024.
[0194] Specifically, an opening 512 may be formed in the first protrusion 510 and the fixing platform 500. The diameter of the opening 512 may be larger than the diameter of the shank of the first T-shaped screw 5013 and smaller than the diameter of the head of the first T-shaped screw 5013. In this case, the shank of the first T-shaped screw 5013 can pass through the opening 512, but the head of the first T-shaped screw 5013 is located above the opening 512. The second protrusion 520 and the fixing platform 500 may also form an opening 522. The diameter of the opening 522 may be larger than the diameter of the shank of the second T-shaped screw 5023 and smaller than the diameter of the head of the second T-shaped screw 5023. In this case, the shank of the second T-shaped screw 5023 can pass through the opening 522, but the head of the second T-shaped screw 5023 is located above the opening 522.
[0195] During assembly of the touchpad 1, the head of the first T-shaped screw 5013 can abut against the first travel switch 101, and the head of the second T-shaped screw 5023 can abut against the second travel switch 301. The pre-compression device can apply a preset force to the bottoms of the first T-shaped screw 5013 and the second T-shaped screw 5023. This preset force can be adjusted and designed based on the actual pressure applied by the user to the touchpad 1. Under this pre-compression force, the first T-shaped screw 5013 and the first travel switch 101 can be in a pre-compression state, and the second T-shaped screw 5023 and the second travel switch 301 can be in a pre-compression state. This state can sensitively detect the user's pressure on the touchpad 1.
[0196] While the pre-stressing device applies a preset force to the bottom of the first T-shaped screw 5013 and the second T-shaped screw 5023, in order to enable the first T-shaped screw 5013 to maintain a pre-stressed state, a glue layer 5014 can be formed by dispensing glue in the opening 512, thereby fixing the first T-shaped screw 5013 to the opening 512. In order to enable the second T-shaped screw 5023 to maintain a pre-stressed state, a glue layer 5024 can be formed by dispensing glue in the opening 522, thereby fixing the second T-shaped screw 5023 to the opening 522.
[0197] The head of the first T-shaped screw 5013 can prevent the glue layer 5014 from overflowing to the first travel switch 101, ensuring the reliable use of the first travel switch 101. The head of the second T-shaped screw 5023 can prevent the glue layer 5024 from overflowing to the second travel switch 301, ensuring the reliable use of the second travel switch 301.
[0198] Through the technical solution of this embodiment, there is no need to adjust the distance and interaction force between the touch panel and the travel switch by adjusting the screw. Instead, the T-shaped screw and the rubber layer can cooperate with each other to keep the T-shaped screw and the travel switch in a pre-stressed state suitable for the user's pressing action, thereby more sensitively and conveniently detecting the user's pressing on the touch panel 1, and also ensuring the user's pressing feel on the touch panel 1.
[0199] It can be understood that the relevant technical solutions of the first adjusting screw 5011 and the second adjusting screw 5021 and the first T-shaped screw 5013 and the second T-shaped screw 5023 shown in Figures 11 and 12 can also be applied to any of the embodiments shown in Figures 1 to 11 above, that is, the first contact 501 in any embodiment shown in Figures 1 to 11 can be replaced with the first adjusting screw 5011 or the first T-shaped screw 5013, and the second contact 502 in any embodiment shown in Figures 1 to 11 can be replaced with the second adjusting screw 5021 or the second T-shaped screw 5023.
