[0001] This application claims priority to the following applications, the entire contents of which are incorporated herein by reference:

[0002] An international application entitled "A Support Component, Touchpad and Electronic Device" was filed with the Chinese Patent Office on May 23, 2022, with application number PCT / CN2022 / 094326.

[0003] On March 11, 2022, a Chinese invention application was filed with the Chinese Patent Office with application number 202210249829.X and the invention title "Touchpad Module and Electronic Device Using Touchpad Module". Technical Field

[0004] This application relates to the field of touch technology, and more specifically, to a touchpad and an electronic device. Background Technology

[0005] With technological innovation and progress, laptop touchpads have become a replacement for external mice. The greater the input capacity of the touchpad, the higher the demands of consumers for the user experience.

[0006] like Figure 1 As shown in Figure (a), the existing split touchpad consists of two separate components: a touch panel 1 and mechanical buttons 2. The touch panel 1 cannot be pressed, resulting in a more complex structure that affects human-computer interaction and aesthetics. Figure 1 As shown in Figure (b), the integrated touchpad combines the touch panel and buttons into a single board. The limit switch is located at the lower part of the module and is pressed using a single lever structure. However, only the lower half of the area 3 is functional when pressed. Furthermore, the touchpad module occupies a large space in the whole device, affecting the battery capacity. In addition, the feel is not consistent when pressing, which affects the user experience. Summary of the Invention

[0007] This application provides a touchpad and an electronic device that enables full-area pressing and provides balanced force feedback to the user.

[0008] In a first aspect, a touchpad is provided, comprising: a touch component for receiving a user's press, wherein a limit switch is provided on the lower surface of the touch component; a support component, comprising: a main support member disposed at the edge of the lower surface of the touch component, the main support member being frame-shaped and having a first side and a second side opposite to each other; a first elastic member and a second elastic member disposed below the main support member and symmetrically arranged along the plane of the main support member; a fixed platform disposed below the first elastic member and the second elastic member, the first elastic member being connected between the first side of the main support member and the fixed platform, the second elastic member being connected between the second side of the main support member and the fixed platform, and a contact point being provided on the surface of the fixed platform facing the touch component; when the touch component is pressed, the touch component moves along the pressing direction, the first elastic member and the second elastic member undergo elastic deformation, and the contact point on the fixed platform contacts and triggers the limit switch on the touch component.

[0009] Through the technical solution of the embodiments of this application, the touch panel composed of the touch component and the support component with two elastic elements can not only realize full-area pressing, but also provide users with balanced force feedback. The overall performance of the touch panel is better, and it can be better applied to various types of electronic devices and improve the user experience.

[0010] In some possible implementations, the support assembly further includes: a first attachment and a second attachment, the first attachment being attached to the upper surface of the first elastic member and having a first protrusion extending above the second elastic member; the second attachment being attached to the upper surface of the second elastic member and having a second protrusion located above the first elastic member.

[0011] In some possible implementations, a first side of the first elastic member is connected to a first side of the main support member, and a first protrusion is provided above the second side of the first elastic member, wherein the second side of the first elastic member is opposite to the first side of the first elastic member, and an elastic connector connected to the fixed platform is provided between the first side and the second side of the first elastic member; a first side of the second elastic member is connected to a second side of the main support member, and a second protrusion is provided above the second side of the second elastic member, wherein the second side of the second elastic member is opposite to the first side of the second elastic member, and an elastic connector connected to the fixed platform is provided between the first side and the second side of the second elastic member.

[0012] With the technical solution of this embodiment, when a user presses one end of the touch component, for example, when the user presses the end area of ​​the touch component near the first side of the main support member or the end area of ​​the touch component near the first side of the main support member, the other end of the touch component will not lift up under the combined action of the elastic member and the connecting member, so as to further improve the press detection performance of the touch panel.

[0013] In some possible implementations, the first attachment is further used to reinforce the first elastic member, and the second attachment is further used to reinforce the second elastic member.

[0014] By combining the first attachment and the second attachment, the technical solution of this embodiment can ensure the elastic deformation of the first elastic member and the second elastic member, while also ensuring the reliability and service life of the first elastic member and the second elastic member.

[0015] In some possible implementations, the touch component is a rectangular touch component, the first elastic member has two first elastic arms parallel to the long side direction of the rectangular touch component and a first middle portion connecting the two first elastic arms, the second elastic member has two second elastic arms parallel to the long side direction of the rectangular touch component and a second middle portion connecting the two second elastic arms; the two first elastic arms and the two second elastic arms correspond to each other and have a gap.

[0016] With the technical solution of this embodiment, the two first elastic arms of the first elastic member and the two second elastic arms of the second elastic member are parallel to the length direction of the rectangular touch component, so that the first elastic member and the second elastic member can better ensure the user's pressing feel in the length direction of the touch component and ensure the touchpad's detection of the user's pressing.

[0017] In some possible implementations, the first attachment has two first connecting arms attached to the upper surfaces of the two first elastic arms, and the second attachment has two second connecting arms attached to the upper surfaces of the two second elastic arms; the two first connecting arms and the two second connecting arms correspond to each other and have a gap, and the two first connecting arms have a first protrusion located above the two second elastic arms at one end facing the two second connecting arms, and the two second connecting arms have a second protrusion located above the two first elastic arms at one end facing the two first connecting arms.

[0018] In some possible implementations, the recesses corresponding to the first protrusions of the two first connecting arms are used to accommodate the second protrusions of the two second connecting arms; the recesses corresponding to the second protrusions of the two second connecting arms are used to accommodate the first protrusions of the two first connecting arms.

[0019] With the technical solution of this embodiment, the first protrusion and the second protrusion between the two first connecting arms and the two second connecting arms can be adapted to each other, without causing additional space waste, and can reliably ensure the touch panel's press detection performance.

[0020] In some possible implementations, at least one first elastic connector is provided on the side of the first middle portion facing the first side of the main support member, and the first elastic connector is connected to the first side of the main support member through at least one first elastic connector; at least one second elastic connector is provided on the other side of the first middle portion away from the first side of the main support member, and the first elastic connector is connected to the fixed platform through at least one second elastic connector.

[0021] In some possible implementations, at least one third elastic connector is provided on the side of the second middle portion facing the second side of the main support member, and the second elastic connector is connected to the second side of the main support member through at least one third elastic connector; at least one fourth elastic connector is provided on the other side of the second middle portion away from the second side of the main support member, and the second elastic connector is connected to the fixed platform through at least one fourth elastic connector.

[0022] The technical solution of this embodiment provides elastic connectors on both sides of the first middle part of the first elastic member and elastic connectors on both sides of the second middle part of the second elastic member, so as to realize the elastic connection between the first elastic member and the second elastic member between the main support member and the fixed platform. The overall method is easy to implement and the connection area between the first elastic member and the second elastic member and the main support member and the fixed platform is small, which can effectively ensure the elastic deformation of the first elastic member and the second elastic member, thereby ensuring the pressing performance of the touch panel.

[0023] In some possible implementations, a through hole is provided in the first intermediate portion, and / or, a through hole is provided in the second intermediate portion.

[0024] The technical solution of this embodiment can reduce the overall weight of the first elastic element and / or the second elastic element, and can provide space for other devices in the touchpad.

[0025] In some possible implementations, the projection of the fixed platform onto the plane where the touch component is located extends beyond the touch component.

[0026] The technical solution of this embodiment has a fixed platform that extends beyond the touch component. Therefore, the fixed platform can have a large area, thereby providing good support and protection for the touch component and improving the overall stability of the touch panel.

[0027] In some possible implementations, the touch component is a rectangular component, and the projection of the fixing platform onto the plane where the touch component is located extends beyond the touch component in the length and / or width directions of the touch component.

[0028] In some possible implementations, the portion of the fixed platform extending beyond the touch component is provided with a mounting bracket for mounting the fixed platform to the electronic device where the touchpad is located.

[0029] The technical solution of this embodiment allows the touchpad to be directly installed on electronic devices using a fixed platform. The overall installation method is easy to implement and highly reliable, which helps to improve the assembly efficiency of the touchpad in electronic devices and facilitates its disassembly and maintenance.

[0030] In some possible implementations, the central region of the fixed platform is provided with a protrusion facing the touch component, a first elastic member and a second elastic member are connected to the protrusion, and the first elastic member and the second elastic member have gaps with other regions of the fixed platform other than the protrusion.

[0031] By providing a protrusion in the central area of ​​the fixed platform, the protrusion can cooperate with the first elastic member and the second elastic member to realize the touch panel's press detection function. It also allows for a larger area design of the fixed platform. For example, the fixed platform can have a portion that extends beyond the touch component, thereby providing reliable support and protection for the touch component.

[0032] In some possible implementations, the first elastic member and the second elastic member are used to enclose the opening area corresponding to the protrusion.

[0033] With the technical solution of this embodiment, when the user presses on the touch component, the protrusion will not interfere with or affect the elastic deformation of the first elastic element and the second elastic element, so as to reliably ensure the press detection performance of the touch panel.

[0034] In some possible implementations, the protrusion is a hollow protrusion, or the protrusion is a solid reinforcement.

[0035] With the technical solution of this embodiment, when the protrusion is a hollow protrusion, it is easy to form in the fixed platform, resulting in a smaller overall weight and lower cost for the fixed platform. When the protrusion is a solid reinforcing part, it can not only form a protrusion on the surface of the fixed platform, but also improve the connection strength between the fixed platform and the first and second elastic members.

[0036] In some possible implementations, the contact is located in the central region of the protrusion.

[0037] In some possible implementations, the contact is a boss located on the protrusion and protruding toward the touch component.

[0038] In this embodiment, the fixed platform is used to cooperate with the contact implementation of the limit switch. This method is simple and has a low manufacturing cost, which helps to improve the production efficiency of the touch panel and reduce the overall manufacturing cost of the touch panel.

[0039] In some possible implementations, the contact is an adjusting screw mounted on the protrusion, and the height of the adjusting screw relative to the protrusion can be adjusted.

[0040] In this embodiment, the height-adjustable screw can better fit the limit switch, making the limit switch more sensitive and accurate in sensing pressing pressure. Furthermore, the height-adjustable screw can tolerate deformation of the fixed platform and thickness tolerances of the limit switch. In other words, even if the fixed platform is deformed and / or the limit switch has thickness tolerances, the distance and interaction force between the adjusting screw and the limit switch can be adjusted by adjusting the screw to ensure a good fit between the limit switch and the adjusting screw, thereby ensuring the touchpad's press detection performance.

[0041] In some possible implementations, the contact is a T-shaped screw disposed on the protrusion, with the head of the T-shaped screw facing the limit switch, and the T-shaped screw is fixed to the opening of the protrusion by an adhesive layer.

[0042] The technical solution of this embodiment eliminates the need to adjust the distance and interaction force between the limit switch and the screw. Instead, the T-screw and the limit switch can be kept in a pre-pressed state adapted to the user's pressing action through the cooperation of the T-screw and the adhesive layer. This allows for more sensitive and convenient detection of the user's pressing action on the touchpad, while also ensuring the user's pressing feel on the touchpad.

[0043] In some possible implementations, the edge of the main support member is provided with a limiting portion, which is used to limit the main support member.

[0044] Through the technical solution of this embodiment, the main support member, as the central component of the touch panel, ensures the overall strength and structural stability of the touch panel. The limiting part is set on the main support member to limit the main support member in the electronic device, which can reliably ensure the overall limiting of the touch panel in the electronic device, thereby reliably ensuring the installation and use of the touch panel in the electronic device.

[0045] In some possible implementations, the edge of the fixed platform is curved upward to form a stepped structure, and the sidewall of the stepped structure forms a limiting hole. The limiting hole and the limiting part cooperate with each other so that the fixed platform limits the main support member.

[0046] The technical solution of this embodiment allows for the limitation of the main support component using a fixed platform within the touchpad, eliminating the need for additional limiting holes in the electronic device. While ensuring the touchpad itself has a relatively stable structure, it simplifies the installation of the touchpad in electronic devices and facilitates its disassembly and maintenance.

[0047] In some possible implementations, the size of the limiting hole is larger than the size of the limiting portion in a direction perpendicular to the plane of the touch component.

[0048] Through the technical solution of this embodiment, the larger limiting hole can provide a certain downward movement space for the limiting part, thereby facilitating the user's pressing on the touch component and improving the user's experience of using the touchpad.

[0049] In some possible implementations, at least one component of the support assembly is provided with a pressure groove for controlling the flatness of at least one component.

[0050] The technical solution of this embodiment, which utilizes pressure point grooves to control the flatness of at least one component in the support assembly, can further optimize the performance parameters of the touchpad and improve the user experience.

[0051] In some possible implementations, the mounting platform is provided with through holes to avoid other components in the electronic device where the touchpad is located and to reduce the weight of the mounting platform.

[0052] In a second aspect, an electronic device is provided, comprising: a housing, and a touchpad as described in the first aspect or any possible embodiment of the first aspect, the touchpad being mounted on the housing. Attached Figure Description

[0068] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0069] This application relates to a touchpad (or touch panel). Specifically, the touchpad can provide an interface for interaction with a user's fingers through touch and pressing. In the pressing interface, the touchpad can sense the user's pressing operation to execute corresponding pressing feedback or instruct the electronic device to perform a corresponding function; this pressing interface can function as a "button". In the touching interface, the touchpad can sense the position and movement of the user's fingers to execute corresponding touch feedback or instruct the electronic device to perform a corresponding function; this touching interface can function as a "mouse".

[0070] The touchpad can be applied to any human-computer interaction device, such as laptops, tablets, mobile phones, smart wearable devices, smart door locks, automated teller machines (ATMs), etc., and the embodiments disclosed herein are not limited to this.

[0071] In existing technologies, touchpads require dedicated mechanical components, such as levers, for pressure detection. This not only fails to achieve full-area pressure detection but also results in inconsistent pressure from the user, leading to a poor user experience. Therefore, this application provides a novel touchpad capable of full-area pressure detection and providing balanced force feedback at any location on the touchpad.

[0072] Figure 2 and Figure 3 A schematic cross-sectional view and a schematic exploded view of a touchpad 10 provided in an embodiment of this application are shown.

[0073] like Figure 2 and Figure 3 As shown, the touchpad 10 includes a touch component 100 and a support component 200.

[0074] Specifically, the touch component 100 is used to receive the user's press, and a limit switch 101 is provided on the lower surface of the touch component 100.

[0075] The support assembly 200 includes: a main support 210, a first elastic element 220, a second elastic element 230, and a fixed platform 240.

[0076] The main support member 210 is disposed on the edge of the lower surface of the touch component 100, and the main support member 210 is frame-shaped with a first side 211 and a second side 212 facing each other. A first elastic member 220 and a second elastic member 230 are disposed below the main support member 210 and symmetrically connected to the main support member 210 along the plane of the main support member 210. A fixed platform 240 is disposed below the first elastic member 220 and the second elastic member 230. The first elastic member 220 connects the first side 211 of the main support member 210 and the fixed platform 240, and the second elastic member 230 connects the second side 212 of the main support member 210 and the fixed platform 240. The fixed platform 240 has contact points 241 on its surface facing the touch component 100.

[0077] When any position of the touch component 100 is pressed, the touch component 100 moves downward under force, and the first elastic element 220 and the second elastic element 230 undergo elastic deformation. The contact 241 on the fixed platform 240 contacts and triggers the limit switch 101 on the touch component 100.

[0078] Specifically, the touch component 100 can be a plate-like structure, facilitating the provision of a pressing interface for the user. The touch component 100 may include a circuit board 120. After the touch panel 10 containing the touch component 100 is mounted on the electronic device, the circuit board 120 may be disposed on the lower surface of the cover plate 110, allowing the user to press on the circuit board 120 by pressing on the cover plate 110. Alternatively, in some embodiments, the touch component 100 may directly include a cover plate 110 and a circuit board 120, allowing the touch panel 10 containing the touch component 100 to be directly mounted on the electronic device without requiring an additional cover plate. Optionally, such as... Figure 2 and Figure 3 As shown, the cover plate 110 and the circuit board 120 can be connected to each other by a connector, such as an adhesive layer 111.

[0079] The cover plate 110 is located on the outer surface of the entire touchpad 10 and is a generally flat, rigid sheet of material. Its upper surface is configured to contact one or more user objects, such as fingers or styluses, when the touchpad 10 is operated. Therefore, the user can provide input by clicking, swiping, pressing, or otherwise applying force to the surface of the cover plate 110 using the aforementioned one or more user objects.

[0080] It should be noted that, for ease of description, in this application, "up" and "down" refer to the direction facing the user and the direction away from the user, respectively, rather than the absolute "opposite direction of gravity" and "direction of gravity." Therefore, the upper surface of the cover plate 110 is the surface facing the user, and conversely, the lower surface of the cover plate 110 is the surface away from the user. Similar to the cover plate 110, in the following text, the "up" and "down" directions of other components of the touchpad 10 can also be understood as the direction facing the user and the direction away from the user.

[0081] The cover plate 110 is made of a rigid material, specifically, it can be a rigid object such as glass, polycarbonate (PC) sheet, ceramic sheet, or Mylar sheet. The top surface of the cover plate 110 can be smooth or have a rough texture to make the touchpad appearance conform to the product's aesthetic design. The cover plate 110 can be generally rectangular in shape, and in some embodiments, the edges of the rectangular outer surface of the cover plate 110 can also be rounded.

[0082] The circuit board 120 can specifically be a printed circuit board (PCB) or a flexible printed circuit board (FPC) with reinforcement. A printed circuit board assembly (PCBA) can be formed by mounting components on the circuit board 120 using surface mount technology (SMT) or configuring touch sensors, limit switches 101, connectors, and other electronic components using dual in-line packages (DIPs). This PCBA can be used to implement touch sensing and pressure detection functions of the touchpad. Optionally, the PCBA can communicate with a laptop keyboard or a leather keyboard via connectors. Optionally, the touch sensor in the PCBA is specifically a touch sensing layer built into the circuit board 120.

[0083] The limit switch 101 may include an elastic structure protruding from the lower surface of the circuit board 120 and a conductive point disposed on the lower surface of the circuit board 120. Cooperatively with the limit switch 101, a contact 241 is disposed on the surface of the fixed platform 240 facing the circuit board 120. This contact 241 may be a protruding structure in the fixed platform 240 facing the circuit board 120. When the user is not pressing on the cover plate 110, the elastic structure may come into contact with or separate from the contact 241. In this case, the state of the elastic structure is its initial state or default state. When the elastic structure is separated from the contact 241, the initial state of the elastic structure is an undeformed state. When the elastic structure comes into contact with the contact 241, the initial state of the elastic structure may be a slightly deformed state or an undeformed state.

[0084] When a user presses their finger on the cover plate 110, the elastic structure in the limit switch 101 moves along the pressing direction and contacts the contact point 241, causing the elastic structure to deform. The deformed elastic structure then contacts the conductive point of the circuit board 120, thus turning on the limit switch 101. After the user withdraws their finger from pressing the cover plate 110, the deformed elastic structure returns to its initial state, no longer contacting the conductive point of the circuit board 120, thereby turning off the limit switch 101. In this limit switch 101, the movement of the elastic structure in the pressing direction can be understood as the pressing stroke of the limit switch 101. As a possible embodiment, the elastic structure in the limit switch 101 can be a dome switch, and the limit switch can be understood as a dome key. Alternatively, in some alternative embodiments, the limit switch 101 can be a switch switch in addition to a dome key. This application does not limit the specific implementation of the limit switch 101.

[0085] Optionally, such as Figure 2 and Figure 3 As shown, the limit switch 101 can be fixed to the central area of ​​the lower surface of the circuit board 120 by adhesive bonding or SMT. Alternatively, in other embodiments, the limit switch 101 can be positioned at other locations on the lower surface of the circuit board 120 as needed.

[0086] In addition to the aforementioned touch component 100, the touchpad 10 also includes a support component 200 for supporting the touch component 100.

[0087] Specifically, in the support assembly 200, the main support member 210 can be a frame-shaped support member, which is disposed on the edge of the lower surface of the circuit board 120. Optionally, the main support member 210 can be connected to the edge of the lower surface of the circuit board 120 by a connector (e.g., adhesive layer 201).

[0088] The shape of the main support member 210 can be adapted to the shape of the circuit board 120. For example, if the circuit board 120 is a rectangular circuit board, the main support member 210 can be a rectangular frame. In addition, the main support member 210 needs to have a certain rigidity and strength to ensure reliable support for the touch component 100 and improve the overall strength of the touch panel 10.

[0089] Furthermore, in the support assembly 200, the fixing platform 240 is a fixedly installed component. The touchpad 10 can be mounted on the electronic device via the fixing platform 240, and the fixing platform 240 can be stably fixed in the electronic device. The fixing platform 240 also needs to have a certain rigidity and strength to ensure reliable support for the touch assembly 100 and improve the overall strength of the touchpad 10.

[0090] In this embodiment, the fixed platform 240 and the main support member 210 are interconnected via a first elastic element 220 and a second elastic element 230. Specifically, the first elastic element 220 is connected between the first side 211 of the main support member 210 and the fixed platform 240, and the second elastic element 230 is connected between the second side 212 of the main support member 210 and the fixed platform 240. When a user presses on the touch component 100, the touch component 100 drives the main support member 210 connected to it to move in the pressing direction. The first elastic element 220 and the second elastic element 230 undergo elastic deformation under the pressing force, and the limit switch 101 in the touch component 100 can contact the contact point 241 on the fixed platform 240 to detect the user's press. After the user withdraws the pressing force, the first elastic element 220 and the second elastic element 230 can return to their original state. These two elastic elements, together with the main support member 210 and the fixed platform 240, can provide good support for the touch component 100.

[0091] In addition, the first elastic element 220 and the second elastic element 230 are symmetrically connected to the main support element 210 along the plane of the main support element 210, so that the first elastic element 220 and the second elastic element 230 have good symmetry in the touchpad 10. They can respectively adapt to the user's pressing in two symmetrical areas in the touchpad 10, so as to provide the user with balanced force feedback.

[0092] In summary, through the technical solution of the embodiments of this application, the touch panel 10, which is composed of the touch component 100 and the support component 200 with two elastic members, can not only realize full-area pressing, but also provide users with balanced force feedback. The overall performance of the touch panel 10 is better, and it can be better applied to various types of electronic devices and improve the user experience.

[0093] In the above Figure 3 In the illustrated embodiment, although the touchpad 10 can be pressed at any position on the touch component 100, when the user presses one end of the touch component 100, the other end may tilt up without constraint. In this case, the tilted touch component 100 will affect the pressing stroke of its limit switch 101, thereby affecting the contact between the limit switch 101 and the contact point 241, and consequently affecting the press detection performance of the touchpad 10.

[0094] In view of this, Figure 3 Based on the illustrated embodiment, Figure 4 A schematic exploded view of another touchpad 10 provided in an embodiment of this application is shown.

[0095] like Figure 4 As shown, the support assembly 200 further includes a first attachment 250 and a second attachment 260, wherein the first attachment 250 is attached to the upper surface of the first elastic member 220 and the second attachment 260 is attached to the upper surface of the second elastic member 230.

[0096] Figure 5 It shows Figure 4 A schematic enlarged view of the first elastic member 220, the second elastic member 230, the first attachment member 250, and the second attachment member 260. Figure 6 A schematic top view of the first elastic member 220, the second elastic member 230, the first attachment 250, and the second attachment 260 after assembly is shown. Figure 6 Figure (b) is Figure 6 An enlarged view of part A in diagram (a).

[0097] Combination Figure 5 and Figure 6As shown, the first attachment 250 has a first protrusion 2501 extending above the second elastic member 230, and the second attachment 260 has a second protrusion 2601 extending above the first elastic member 220.

[0098] Optionally, the first side of the first attachment 250 and the first elastic member 220 is the side close to the first edge 211 of the main support member 210, wherein the first side of the first elastic member 220 is connected to the first edge 211 of the main support member 210. Conversely, the second side of the first attachment 250 and the first elastic member 220 is the side away from the first edge 211 of the main support member 210.

[0099] Similarly, the first side of the second attachment 260 and the second elastic member 230 is the side closer to the second side 212 of the main support member 210, wherein the first side of the second elastic member 220 is connected to the second side 212 of the main support member 210. Conversely, the second side of the second attachment 260 and the second elastic member 230 is the side away from the second side 212 of the main support member 210. An elastic connector connected to the fixed platform 240 is provided between the first and second sides of the first elastic member 220. An elastic connector connected to the fixed platform 240 is provided between the first and second sides of the second elastic member 230. When the user presses on the touch component 100, the elastic connector of the first elastic member 220 connected to the fixed platform 240 between the first and second sides can serve as a force-bearing fulcrum for the first elastic member 220, and the elastic connector of the second elastic member 230 connected to the fixed platform 240 between the first and second sides can serve as a force-bearing fulcrum for the second elastic member 230.

[0100] The first attachment 250 has a first protrusion 2501 on its second side, and the second attachment 260 has a second protrusion 2601 on its second side. In this case, the first protrusion 2501 extends above the second side of the second elastic member 230, and the second protrusion 2601 also extends above the second side of the first elastic member 220.

[0101] When a user presses the area of ​​the touch component 100 near the first side 211 of the 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 time, the second side of the first elastic member 220 can act on the second protrusion 2601 of the second attachment member 260 located above it, causing the second attachment member 260 to drive the second side of the second elastic member 230 to move upward, and the first side of both the second attachment member 260 and the second elastic member 230 to move downward. When the first side of the second elastic member 230 moves downward, the second side 212 of the main support member 210 connected to the first side of the second elastic member 230 also drives the area of ​​the touch component 100 near the second side 212 of the main support member 210 to move downward. Therefore, when a user presses the area of ​​the first side 211 of the touch component 100 near the main support member 210, the area of ​​the second side 212 of the touch component 100 near the main support member 210 will not lift up, thereby further improving the press detection performance of the touchpad 10.

[0102] Similarly, when a user presses the area of ​​the touch component 100 near the second side 212 of the 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 time, the second side of the second elastic member 230 can act on the first protrusion 2501 of the first attachment member 250 located above it, causing the first attachment member 250 to drive the second side of the first elastic member 220 to move upward, and the first attachment member 250 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 main support member 210 connected to the first side of the first elastic member 220 will also drive the area of ​​the touch component 100 near the first side 211 of the main support member 210 to move downward. Therefore, when a user presses the area of ​​the second side 212 of the touch component 100 near the main support member 210, the area of ​​the first side 211 of the touch component 100 near the main support member 210 will not lift up, thereby further improving the press detection performance of the touchpad 10.

[0103] In summary, through the technical solution of this application embodiment, when a user presses one end of the touch component 100, for example, when the user presses the end region of the touch component 100 near the first side 211 of the main support member 210 or the end region of the touch component 100 near the second side 212 of the main support member 210, the other end of the touch component 100 will not lift up under the combined action of the elastic member and the connecting member, so as to further improve the press detection performance of the touch panel 10.

[0104] In addition to improving the press detection performance of the touchpad 10, the first attachment 250, attached to the first elastic member 220, can also reinforce the first elastic member 220, and the second attachment 260, attached to the second elastic member 230, can also reinforce the second elastic member 230.

[0105] Optionally, such as Figures 3 to 6 As shown, both the first elastic element 220 and the second elastic element 230 are sheet-like. Although these sheet-like first and second elastic elements 220 and 230 have good elasticity, their strength is relatively weak. Therefore, in this embodiment, a first attachment 250 and a second attachment 260 are added to the support assembly 200. These first and second attachments 250 and 260 can also be sheet-like, thus facilitating attachment to the first and second elastic elements 220 and 230. Furthermore, the shape of the first attachment 250 can be adapted to the first elastic element 220, and the shape of the second attachment 260 can be adapted to the second elastic element 230. The first and second attachments 250 and 260 can provide better support and reinforcement to the main body areas of the first and second elastic elements 220 and 230.

[0106] By combining the first attachment 250 and the second attachment 260, the elastic deformation of the first elastic element 220 and the second elastic element 230 can be guaranteed, as well as the reliability and service life of the first elastic element 220 and the second elastic element 230.

[0107] Optionally, such as Figures 3 to 6 As shown, the first elastic member 220 and the second elastic member 230 have the same shape. Correspondingly, the first attachment member 250 and the second attachment member 260 may have similar or identical shapes. The first attachment member 250 and the second attachment member 260 may be disposed on the upper surface of the first elastic member 220 and the second elastic member 230. In this case, the first attachment member 250 and the second attachment member 260 may be accommodated in the hollow region of the frame-type main support member 210.

[0108] Optionally, to ensure the elastic performance of the first elastic member 220 and the second elastic member 230, the thickness of the first elastic member 220 and the second elastic member 230 is relatively thin. To ensure the reinforcing performance of the first attachment member 250 and the second attachment member 260, the thickness of the first attachment member 250 and the second attachment member 260 can be relatively thick. As an example, the thickness of the first attachment member 250 and the second attachment member 260 can be greater than the thickness of the first elastic member 220 and the second elastic member 230.

[0109] In some implementations, the touch component 100 is a rectangular touch component. (Refer to reference) Figure 5As shown, the first elastic member 220 has two first elastic arms 221 parallel to the long side direction of the rectangular touch assembly and a first intermediate portion 222 connecting the two first elastic arms 221. The second elastic member 230 has two second elastic arms 231 parallel to the long side direction of the rectangular touch assembly and a second intermediate portion 232 connecting the two second elastic arms 231. In the direction parallel to the long side direction 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.

[0110] With 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 all parallel to the long side direction of the rectangular touch component. 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 touch component 100 and to ensure the touchpad 10's detection of the user's press. In addition, the two first elastic arms 221 and the two second elastic arms 231 can be distributed along the short side direction of the rectangular touch component. Correspondingly, the two first elastic arms 221 distributed along the short side direction can be connected by the first middle portion 222 distributed along the long side direction, and the two second elastic arms 231 distributed along the short side direction can be connected by the second middle portion 232 distributed along the long side direction. This also ensures the user's pressing feel in the short side direction of the touch component 100.

[0111] Optionally, see Figure 5 As shown, through holes may be formed in the first intermediate portion 222 and the second intermediate portion 232 to reduce the overall weight of the first elastic member 220 and the second elastic member 230, and to provide accommodating space for other devices in the touch panel 10, such as providing accommodating space for components on the lower surface of the circuit board 120.

[0112] Alternatively, in other alternative embodiments, the first intermediate portion 222 and the second intermediate portion 232 may also be solid portions, that is, without through holes, to ensure the reliability of the first elastic member 220 and the second elastic member 230. Furthermore, the position of the solid portion should avoid other components in the touch panel 10, such as components on the lower surface of the circuit board 120.

[0113] 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 main support member 210, and the first elastic member 220 is connected to the first side 211 of the main support member 210 through 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 main support member 210, and the first elastic member 220 is connected to the fixed platform 240 through the at least one second elastic connector 2222. As an example, in Figure 5In the embodiment shown, two first elastic connectors 2221 and two second elastic connectors 2222 are respectively provided on both sides of the first middle part 222.

[0114] At least one fourth elastic connector 2322, connected to the fixed platform 240, is disposed between the two first elastic arms 221 and located between the first side of the first elastic member 220 near the first side 211 of the main support member 210 and the second side away from the first side 211 of the main support member 210. When the user presses on the touch component 100, the at least one fourth elastic connector 2322 can serve as a force-bearing fulcrum for the first elastic member 220.

[0115] 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 intermediate portion 222. In this case, the at least one first elastic connector 2221 and the at least one second elastic connector 2222 can be understood as a cantilever beam structure disposed on the first intermediate portion 222. Alternatively, in other embodiments, the at least one first elastic connector 2221 and the at least one second elastic connector 2222 may also be separate structures from the first intermediate portion 222, with the at least one first elastic connector 2221 and the at least one second elastic connector 2222 connected to the first intermediate portion 222 by an adhesive layer, welding, or other connection methods.

[0116] It is understood that after the first elastic member 220 is connected to the first side 211 of the main support member 210 through at least one first elastic connector 2221, the middle area of ​​the first elastic connector 2221, except for the two end areas, is in a suspended state, thereby ensuring the elastic connection between the first elastic member 220 and the first side 211 of the main support member 210. Furthermore, after the first elastic member 220 is connected to the fixed platform 240 through at least one second elastic connector 2222, the middle area of ​​the second elastic connector 2222, except for the two end areas, is in a suspended state, thereby ensuring the elastic connection between the first elastic member 220 and the first side 211 of the fixed platform 240.

[0117] 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 middle portion 232 facing the second side 212 of the main support member 210, and the second elastic member 230 is connected to the second side 212 of the main support member 210 through at least one third elastic connector 2321. At least one fourth elastic connector 2322 is provided on the other side of the second middle portion 232 away from the second side 212 of the main support member 210, and the second elastic member 230 is connected to the fixed platform 240 through the at least one fourth elastic connector 2322. As an example, in Figure 5In the illustrated embodiment, two third elastic connectors 2321 and two fourth elastic connectors 2322 are respectively provided on both sides of the second intermediate portion 232. Specifically, the design of the third elastic connectors 2321 and fourth elastic connectors 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 elaborated further here.

[0118] The technical solution of this application embodiment provides elastic connectors on both sides of the first middle portion 222 of the first elastic member 220 and on both sides of the second middle portion 232 of the second elastic member 230, thereby achieving an elastic connection between the first elastic member 220 and the second elastic member 230 between the main support member 210 and the fixed platform 240. This allows the first elastic member 220 and the second elastic member 230 to deform when the user presses the touch component 100. The overall approach is easy to implement, and the connection area between the first elastic member 220 and the second elastic member 230 and the main support member 210 and the fixed platform 240 is small, effectively ensuring the elastic deformation of the first elastic member 220 and the second elastic member 230, thus guaranteeing the pressing performance of the touchpad 10.

[0119] Corresponding to the first elastic element 220 and the second elastic element 230 mentioned above, see continue to the next section. Figure 5 As shown, the first attachment 250 has two first connecting arms 251 attached to the upper surfaces of the two first elastic arms 221, and the second attachment 260 has two second connecting arms 261 attached to the upper surfaces of the two second elastic arms 231. The two first connecting arms 251 and the two second connecting arms 261 correspond to each other and have a gap. The two first connecting arms 251 have a first protrusion 2501 located above the two second elastic arms 231 at one end facing the two second connecting arms 261, and the two second connecting arms 261 have a second protrusion 2601 located above the two first elastic arms 221 at one end facing the two first connecting arms 251.

[0120] Specifically, in this embodiment, the two first connecting arms 251 of the first attachment 250 are attached to the two first elastic arms 221 on the upper surface of the first elastic member 220 to support and reinforce the two first elastic arms 221. Similarly, the two first connecting arms 261 of the second attachment 260 are attached to the two second elastic arms 231 on the upper surface of the second elastic member 230 to support and reinforce the two second elastic arms 231. Optionally, the first attachment 250 and the second attachment 260 can be attached to the upper surfaces of the first elastic member 220 and the second elastic member 230 respectively by means of adhesion, welding, stamping, etc.

[0121] Two first protrusions 2501 are provided at one end of each of the two first connecting arms 251 facing the two second connecting arms 261, and these two first protrusions 2501 are located above the two second elastic arms 231. When the user presses on the touch component 100, the two first protrusions 2501 act on the ends of the two second elastic arms 231. Two second protrusions 2601 are provided at one end of each of the two second connecting arms 251, and these two second protrusions 2601 are located above the two first elastic arms 221. When the user presses on the touch component 100, these two second protrusions 2601 act on the ends of the two first elastic arms 221.

[0122] Understandably, the first attachment 250 also has a middle portion connecting the two first connecting arms 251, and the second attachment 260 also has a middle portion connecting the two second connecting arms 261. The middle portion of the first attachment 250 can be attached to the first middle portion 222 of the first elastic member 220, and the middle portion of the second attachment 260 is attached to the second middle portion 232 of the second elastic member 230.

[0123] When the first intermediate portion 222 and the second intermediate portion 232 have through holes, the intermediate portion of the first attachment 250 and the intermediate portion of the second attachment 260 can also be formed with through holes to reduce the overall weight of the first attachment 250 and the second attachment 260, and to provide accommodation space for other devices in the touch panel 10, such as providing accommodation space for components on the lower surface of the circuit board 120.

[0124] See Figure 5 and Figure 6 As shown, the recesses corresponding to the first protrusions 2501 of the two first connecting arms 251 are used to accommodate the second protrusions 2601 of the two second connecting arms 261. The recesses corresponding to the second protrusions 2601 of the two second connecting arms 261 are used to accommodate the first protrusions 2501 of the two first connecting arms 251.

[0125] Through the technical solution of this embodiment, the first protrusion 2501 and the second protrusion 2601 between the two first connecting arms 251 and the two second connecting arms 261 can be adapted to each other without causing additional space waste, and the press detection performance of the touch panel 10 is reliably guaranteed. In some embodiments, at least one component in the support assembly 200 is provided with a pressure point groove, which can be used to control the flatness of the at least one component.

[0126] As an example, the main support member 210, the first elastic member 220, the second elastic member 230, the first attachment member 250, and the second attachment member 260 in the support assembly 200 are all provided with pressure point grooves. These pressure point grooves can be provided on the upper and lower surfaces of each component to adjust the flatness of each component.

[0127] Specifically, excessive flatness in any component of the support assembly 200 can lead to poor consistency in the pressing force of the touchpad 10. This means that different pressure points on the touchpad 10 require varying amounts of force, and the pressure fluctuations are also significant. Furthermore, excessive flatness necessitates consideration of the flatness effect during the pressing stroke, resulting in a longer pressing stroke and negatively impacting the user experience. Therefore, using pressure point grooves for flatness control design can further optimize the performance parameters of the touchpad 10 and improve the user experience.

[0128] In some embodiments, the pressure groove can be a square groove with a side length of 0.15 mm. Alternatively, the pressure groove can also be a circular groove or other polygonal groove, and its depth on the main support 210, the fixing platform 240, the elastic members 220, 230, and the connectors 250, 260 can vary. As an example, the depth of the pressure groove on the main support 210 can be 0.06 mm to 1 mm to control the flatness of the main support 210 to be less than 0.15 mm. The depth of the pressure groove on the fixing platform 240 can be 0.04 mm to 0.08 mm, and the flatness of the fixing platform 240 can be controlled by the user to be less than 0.05 mm. The depth of the pressure groove on the first elastic member 220 and the second elastic member 230 can be 0.02 mm to 0.05 mm. The depth of the pressure groove on the first attachment 250 and the second attachment 260 can be 0.04 mm to 0.08 mm.

[0129] In another alternative implementation, pressure grooves can be provided on the upper and lower surfaces of two components in the support assembly 200 to control the overall flatness of the two components. For example, pressure grooves are provided on both the upper and lower surfaces of the main support 210 and the fixed platform 240, while pressure grooves are provided on only one surface of the first elastic member 220, the second elastic member 230, the first attachment 250, and the second attachment 260. That is, the surfaces of the first elastic member 220 and the first attachment 250 that are in contact do not have pressure grooves, and the surfaces of the second elastic member 230 and the second attachment 260 that are in contact do not have pressure grooves.

[0130] In some possible implementations, as described above Figures 2 to 4 As shown, the projection of the fixed platform 240 onto the plane where the touch component 100 is located extends beyond the touch component 100.

[0131] Specifically, each component in the touch assembly 100 is a plate-shaped part. The plane on which the touch assembly 100 is located can be the plane on which the cover plate 110 in the touch assembly 100 is located, or it can be the plane on which the circuit board 120 is located.

[0132] The projection of the fixed platform 240 onto the plane of the cover plate 110 can extend beyond the cover plate 110, and the projection of the fixed platform 240 onto the plane of the circuit board 120 can also extend beyond the circuit board 120. That is, in this embodiment, in the direction parallel to the plane of the touch component 100, the fixed platform 240 has a portion that extends beyond the touch component 100. Therefore, the fixed platform 240 can have a large area, thereby providing good support and protection for the touch component 100 and improving the overall stability of the touchpad 10.

[0133] In some embodiments, the touch component 100 is a rectangular component, meaning that both the cover plate 110 and the circuit board 120 in the touch component 100 are rectangular. In this case, the projection of the fixing platform 240 onto the plane where the touch component 100 is located extends beyond the touch component 100 in the length and / or width directions.

[0134] As an example, such as Figures 2 to 4 As shown, the fixing platform 240 extends beyond the touch component 100 in both its length and width directions. The area of ​​the fixing platform 240 can be larger than the area of ​​any component in the touch component 100, and the fixing platform 240 can completely cover the touch component 100 from bottom to top. In this example, the fixing platform 240 can provide relatively complete protection and support for the touch component 100.

[0135] Or, in another example, Figure 7 A schematic exploded view of another touchpad 10 provided in an embodiment of this application is shown.

[0136] like Figure 7 As shown in this embodiment, the fixed platform 240 may extend beyond the touch component 100 in the width direction. However, the fixed platform 240 does not extend beyond the touch component 100 in the length direction. In this example, although the fixed platform 240 does not completely cover the touch component 100 from bottom to top, the overall area of ​​the fixed platform 240 can be appropriately reduced, which helps to reduce the overall weight of the touchpad 10 and also reduces the space required for the touchpad 10 in the electronic device.

[0137] Optionally, in some embodiments, the portion of the fixed platform 240 extending beyond the touch assembly 100 is provided with a mounting element for mounting the fixed platform 240 to the electronic device where the touchpad 10 is located.

[0138] As an example, mounting components include, but are not limited to, screw holes and screws, clips, adhesive layers, and other parts used to achieve connection and installation. Specifically, when the mounting components include screw holes and screws, the edge area of ​​the fixing platform 240 may be provided with screw holes, through which screws can fix the fixing platform 240 to the electronic device.

[0139] When the electronic device containing the touchpad 10 is a laptop computer, the mounting component can mount the touchpad 10 to the C-shell of the laptop computer, that is, the shell on the side where the keyboard is located in the laptop computer. For example, the C-shell has a through hole for accommodating the touchpad 10, and the mounting component can mount the fixing platform 240 to the edge of the through hole so that the touchpad 10 is mounted and accommodated in the through hole of the C-shell.

[0140] The technical solution of this embodiment allows the touchpad 10 to be directly installed on the electronic device using the fixed platform 240. The overall installation method is easy to implement and has high reliability, which helps to improve the assembly efficiency of the touchpad 10 in the electronic device and also facilitates its disassembly and maintenance.

[0141] Figure 8 The above text is shown. Figure 4 and Figure 7 A schematic diagram of the fixed platform 240 in the illustrated embodiment. Wherein, Figure 8 Figure (a) in the middle corresponds to Figure 4 The fixed platform 240 in the illustrated embodiment, Figure 8 Figure (b) in the middle corresponds to Figure 7 Fixed platform 240 in the illustrated embodiment.

[0142] like Figure 8 As shown in this embodiment, the fixed platform 240 has a protrusion 242 facing the touch component 100 in its central region. The contact point 241 may be located in the central region of the protrusion 242.

[0143] Optionally, the protrusion 242 can be a rectangular protrusion, which can fit into the rectangular space formed by the first elastic member 220 and the second elastic member 230. Optionally, the contact 241 can be a protrusion located in the central region of the protrusion 242. The area and height of the contact 241 can be designed according to the limit switch 101 on the circuit board 120 so that the contact 241 can effectively contact and trigger the limit switch 101. Figures 2 to 8 As shown, the first elastic member 220 and the second elastic member 230 can be connected to the protrusion 242 to achieve mutual connection between the first elastic member 220 and the second elastic member 230 and the fixed platform 240. Furthermore, there are gaps between the first elastic member 220 and the second elastic member 230 and other areas of the fixed platform 240 besides the protrusion 242.

[0144] Specifically, at least one second elastic connector 2222 on the first intermediate portion 222 of the first elastic member 220 can be connected to the upper surface of the protrusion 242 near the edge of the first intermediate portion 222 to achieve mutual connection between the first elastic member 220 and the fixed platform 240. At least one fourth elastic connector 2322 on the second intermediate portion 232 of the second elastic member 230 can be connected to the upper surface of the protrusion 242 near the edge of the second intermediate portion 232 to achieve mutual connection between the second elastic member 230 and the fixed platform 240. 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 main support member 210 respectively, and there is a gap between the first elastic connector 2221 and the second elastic connector 2321 and the fixed platform 240.

[0145] In this embodiment, there is a gap between the first elastic member 220 and the second elastic member 230 and other areas of the fixed platform 240 except for the protrusion 242. This gap can provide deformation space for the first elastic member 220 and the second elastic member 230 to ensure that the touch component 100 can be displaced downward under the user's pressing action, thereby ensuring the pressing detection function of the touch panel 10.

[0146] By providing a protrusion 242 in the central area of ​​the fixed platform 240, the protrusion 242 can cooperate with the first elastic member 220 and the second elastic member 230 to realize the press detection function of the touch panel 10. It also allows for a larger area design of the fixed platform 240. For example, the fixed platform 240 can have a portion that extends beyond the touch component 100, thereby providing reliable support and protection for the touch component 100.

[0147] Figure 9 It shows Figure 4 The diagram shows the assembly structure of the first elastic element 220 and the second elastic element 230 with the fixed platform 240 in the embodiment shown.

[0148] like Figure 9 As shown in the embodiment of this application, the first elastic member 220 and the second elastic member 230 are symmetrically arranged along the direction parallel to the short side of the touch panel 10, and enclose an opening area corresponding to the protrusion 242.

[0149] Specifically, the two first elastic arms 221 of the first elastic member 220 and the two second elastic arms 232 of the second elastic member 230 are disposed around the protrusion 242. When the user presses on the touch assembly 100, the protrusion 242 will not interfere with or affect the two first elastic arms 221 of the first elastic member 220 and the two second elastic arms 232 of the second elastic member 230. In addition, the two first elastic arms 221 of the first elastic member 220 and the two second elastic arms 232 of the second elastic member 230 can be evenly and symmetrically distributed in the touchpad 10 to further improve the pressing uniformity of the touchpad 10, thereby providing the user with balanced force feedback.

[0150] 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 disposed on the outer periphery of the protrusion 242 parallel to the short side direction of the touch panel 10. The first middle portion 222 of the first elastic member 220 and the second middle portion 232 of the second elastic member 230 are disposed on the outer periphery of the protrusion 242 parallel to the long side direction of the touch panel 10. The two sides of the protrusion 242 parallel to the long side direction of the touch panel 10 are respectively connected to the first middle portion 222 and the second middle portion 232 through at least one second elastic connector 2222 and at least one fourth elastic connector 2322.

[0151] Through the technical solution of this embodiment, the protrusion 242 will not interfere with or affect the elastic deformation of the first elastic member 220 and the second elastic member 230, so as to reliably ensure the press detection performance of the touch panel 10.

[0152] Optionally, see Figure 8 and Figure 9 As shown, the protrusion 242 in the above-described embodiment can be a hollow protrusion. For example, the hollow protrusion 242 can be a hollow boss formed by stamping the fixed platform 240.

[0153] Through the technical solution of this embodiment, the protrusion 242 is easily formed in the fixed platform 240, and the overall weight of the fixed platform 240 is small and the cost is low.

[0154] Alternatively, in some other possible implementations, the protrusion 242 may also be a solid protrusion. For example, a solid reinforcement may be provided on the upper surface of the fixed platform 240. This solid reinforcement can not only form a protrusion on the surface of the fixed platform 240, but also improve the connection strength between the fixed platform 240 and the first elastic member 220 and the second elastic member 230.

[0155] In this implementation, Figure 10 A schematic exploded view of another fixed platform 240 provided in an embodiment of this application is shown.

[0156] like Figure 10 As shown, the fixed platform 240 is a plate-shaped structure, and a reinforcing part can be provided on its upper surface. Specifically, an "I"-shaped reinforcing plate can be provided in the central area of ​​its upper surface. After the reinforcing plate is connected to the fixed platform 240, a protrusion 242 can be formed on the surface of the fixed platform 240.

[0157] Alternatively, the reinforcing plate can be attached to the fixed platform using various methods such as screws, adhesive, or welding. As an example, Figure 10 The reinforcing plate shown is in the shape of an "I". In other alternative embodiments, the reinforcing plate can be adjusted to other shapes according to actual needs. This application does not specifically limit this.

[0158] Combination Figure 8 and Figure 10 As shown, in the various fixed platforms 240 provided in the embodiments of this application, one or more through holes are provided. The through holes can be used to reduce the weight of the fixed platform 240 and can also be used to avoid other components in the electronic device where the touch panel 10 is located, thereby optimizing the overall performance of the touch panel 10 and the electronic device where it is located.

[0159] Optionally, in Figure 8 In the illustrated embodiment, the through hole can be provided in the protrusion 242 of the fixed platform 240, or the through hole can also be provided in the non-protruding area of ​​the fixed platform 240. Figure 10 In the embodiment shown, the protrusion 242 serves as a reinforcing part and may not have a through hole, but only has a through hole in the main plate-shaped part of the fixed platform 240.

[0160] Based on this Figure 10 The fixed platform 240 shown is Figure 11 A schematic exploded view of another touchpad 10, including the fixed platform 240, is shown.

[0161] like Figure 11 As shown, the functions of each component in this touchpad 10 are the same as those described above. Figure 4 and Figure 7 The components in the illustrated embodiments have the same function. The difference lies in the shape design of some components in this embodiment, which differs from the above. Figure 4 and Figure 7 The shapes of some components differ in the embodiments shown.

[0162] Specifically, in this touchpad 10, the design of the fixed platform 240 differs from that of the touchpad 10. Figure 4 and Figure 7 The design of the fixed platform 240 in the illustrated embodiment can be found in the above text for related technical solutions. Figure 10 The relevant description of the illustrated embodiment.

[0163] In addition, the shape design of the first elastic member 220 and the second elastic member 230 is similar to... Figure 4 and Figure 7 The two elastic elements in the illustrated embodiment have slightly different shapes. In this embodiment, the first intermediate portion 222 of the first elastic element 220 and the second intermediate portion 232 of the second elastic element 230 do not have through holes, but are solid arm structures. Corresponding to the solid intermediate portions of the first elastic element 220 and the second elastic element 230, the intermediate portions of the first attachment 250 and the second attachment 260 are also solid intermediate portions, and do not have through holes.

[0164] In this embodiment, the touchpad 10 can be mounted on an electronic device, such as the C-shell of a laptop computer, via a fixing platform 240. Although the fixing platform 240 indirectly supports the main support member 210 and the touch component 100 via elastic connectors, the stability of the main support member 210 and the touch component 100 is poor. Furthermore, due to manufacturing and assembly tolerances of the components in the touchpad 10, the overall thickness of the touchpad 10 may change, resulting in the touch component 100 bulging or sinking after being mounted on the electronic device.

[0165] In view of this, in some embodiments of this application, the main support member 210 may be further provided with a limiting part 213 on the basis of the rectangular frame type. The limiting part 213 is used to limit the main support member 210.

[0166] For example, such as Figure 11 As shown, limiting portions 213 are provided on the first side 211 and / or the second side 212 of the main support member 210. As an example, two limiting portions 213 are provided on both the first side 211 and the second side 212 of the main support member 210. In conjunction with these limiting portions 213, limiting holes can be provided in the electronic device where the touchpad 10 is located. For example, limiting holes are provided in the C-shell of a laptop. When the touchpad 10 is installed in the C-shell, the limiting portions 213 on the main support member 210 can be accommodated in the limiting holes to ensure that the relative position of the main support member 210 in the C-shell is fixed, preventing the touch component 100 connected to the main support member 210 from protruding or recessing into the C-shell, resulting in poor assembly of the touchpad 10 in the C-shell. Poor assembly not only affects the aesthetic appearance of the touchpad 10 but also the user's experience of pressing the touchpad 10. Similar to this… Figure 11 The main support member 210 shown above Figure 4 and Figure 7 The main support member 210 in the illustrated embodiment may also be provided with a limiting part 213 to limit the installation of the main support member 210 and the touch component 100 connected thereto in the electronic device.

[0167] In practical implementation, the limiting part 213 can be a protrusion located on the periphery of the frame-shaped main body of the main support member 210. The shape, size, and number of the limiting part 213 can be designed according to actual needs. As an example, Figure 11 As shown, four limiting parts 213 can be disposed at the four corners of the frame-shaped main body of the main support member 210, thereby providing a relatively reliable limiting effect on the main support member 210. These limiting parts 213 include, but are not limited to, block-shaped or plate-shaped structures. Through the technical solution of this embodiment, the main support member 210, as the central component of the touchpad 10, ensures the overall strength and structural stability of the touchpad 10. The limiting parts 213 on the main support member 210 limit the main support member 210 and the touch component 100 connected to it within the electronic device, thereby reliably ensuring the installation and use of the touchpad 10 in the electronic device.

[0168] In addition to providing a limiting hole in the C-shell of the electronic device to cooperate with the limiting part 213 of the main support member 210, in some other embodiments, a limiting hole may also be provided in the fixed platform 240 to limit the main support member 210.

[0169] Figure 12 The diagram shows a schematic exploded view and assembly view of a main support member 210 and a fixed platform 240 provided in an embodiment of this application.

[0170] like Figure 12 As shown, the fixed platform 240 can be connected with Figure 4 The fixed platform 240 in this embodiment has a similar shape, but the difference lies in that the edge of the fixed platform 240 in this application embodiment is curved upward to form a stepped structure 243, and the side wall of the stepped structure 243 forms a limiting hole 244. The limiting hole 244 can cooperate with the limiting part 213 on the main support member 210 so that the fixed platform 240 limits the main support member 210.

[0171] The technical solution of this embodiment allows for the limiting of the main support member 210 using the fixed platform 240 in the touchpad 10, without the need for additional limiting holes in the electronic device. While ensuring that the main support member 210 and the touch component 100 connected to it have a relatively stable structure, the installation of the touchpad 10 in the electronic device can be simplified, and its disassembly and maintenance are also facilitated.

[0172] In some embodiments, the size of the limiting hole 244 is larger than the size of the limiting portion 213 in the direction perpendicular to the touch component 100.

[0173] After the limiting part 213 is installed in the limiting hole 244, the upper surface of the limiting part 213 can abut against the hole wall of the limiting hole 244. When the user presses on the touch component 100, the limiting part 213 can move downward in the limiting hole 244 along with the main support member 210. The larger limiting hole 244 can provide a certain downward movement space for the limiting part 213 while limiting the downward movement limit of the limiting part 213, thereby facilitating the user's pressing on the touch component 100 and preventing the touch component 100 from collapsing due to excessive downward movement, thus improving the user's experience of using the touchpad 10.

[0174] Optionally, in Figure 12 In the illustrated embodiment, the fixed platform 240 can be a rectangular platform, with the edges containing the two short sides of the fixed platform 240 curving upwards to form two strip-shaped stepped structures 243. These two stepped structures 243 can respectively correspond to the two sides of the main support member 210 where the limiting portion 213 is provided.

[0175] Optionally, the stepped surface of the stepped structure 243 may be provided with mounting elements, such as screw holes and screws, for mounting the fixed platform 240 in electronic devices.

[0176] Understandable, Figure 12 For illustrative purposes only, Figure 4 Based on the fixed platform 240 of the illustrated embodiment, another fixed platform 240 with a stepped structure 243 is shown. Except... Figure 12 In addition to the embodiments shown, Figure 11 In the illustrated embodiment, the edge of the fixed platform 240 can also be bent upwards to form a stepped structure 243, and the sidewall of the stepped structure 243 forms a limiting hole 244. Alternatively, in Figure 7 In the embodiment shown, the sidewall of the stepped structure of the fixed platform 240 can also be formed with a limiting hole 244.

[0177] Optionally, in the embodiments described above, the contact 241 on the fixed platform 240 can be a protrusion in the protrusion 242 that protrudes towards the touch component 100. In some related technical solutions, this protrusion can also be referred to as a "conductive base". The protrusion and the protrusion 242 can be an integral structure, or they can be separate structures. In specific implementation, the protrusion can be made of metal or silicone.

[0178] In this embodiment, the fixed platform 240 is used to cooperate with the contacts 241 of the limit switch 101. The implementation method is simple and the manufacturing cost is low, which is conducive to improving the production efficiency of the touch panel 10 and reducing the overall manufacturing cost of the touch panel 10.

[0179] In addition to the bosses in the above-described embodiments, Figure 13 A schematic diagram illustrating the implementation of another contact 241 provided in an embodiment of this application is shown.

[0180] like Figure 13 As shown in the embodiment of this application, the contact 241 can be an adjusting screw 2411 installed on the protrusion 242, and the height of the adjusting screw 2411 relative to the protrusion 242 can be adjusted.

[0181] Optionally, a nut 2412 may be provided on the protrusion 242 to facilitate the installation of the adjusting screw 2411 on the protrusion 242. The adjusting screw 2411 passes through the nut 2412 and protrudes from the protrusion 242. The height of the adjusting screw 2411 protruding from the protrusion 242 can be adjusted, that is, the distance and interaction force between the adjusting screw 2411 and the limit switch 101 can be adjusted.

[0182] Through the technical solution of this embodiment, the adjustable height adjusting screw 2411 can be better adapted to the limit switch 101, making the limit switch 101 more sensitive and accurate in sensing the pressing pressure. In addition, the adjustable height adjusting screw 2411 can also tolerate the deformation of the fixed platform 240 and the thickness tolerance of the limit switch 101. In other words, even if the fixed platform 240 has deformation and / or the limit switch 101 has thickness tolerance, the distance and interaction force between the adjusting screw 2411 and the limit switch 101 can be adjusted by adjusting the screw 2411, so as to ensure a good fit between the limit switch 101 and the adjusting screw 2411, thereby ensuring the pressing detection performance of the touch panel 10.

[0183] Figure 14 A schematic diagram illustrating the implementation of another contact 241 provided in an embodiment of this application is shown.

[0184] like Figure 14 As shown in the embodiment of this application, the contact 241 is a T-shaped screw 2413 disposed on the protrusion 242. The head of the T-shaped screw 2413 faces the limit switch 101, and the T-shaped screw 2413 is fixed to the opening 2421 in the protrusion 242 by the adhesive layer 2414.

[0185] Specifically, an opening 2421 may be formed in the protrusion 242. The diameter of the opening 2421 may be larger than the diameter of the shank of the T-screw 2413 and smaller than the diameter of the head of the T-screw 2413. In this case, the shank of the T-screw 2413 may pass through the opening 2421, but the head of the T-screw 2413 is limited to being located above the opening 2421.

[0186] During the assembly of the touchpad 10, the head of the T-screw 2413 can abut against the limit switch 101. The pre-pressing device can apply a preset force to the bottom of the T-screw 2413. This preset force can be adjusted and designed according to the actual pressing force of the user on the touchpad 10. Under this pre-pressing force, the T-screw 2413 and the limit switch 101 can be in a pre-pressed state, which can sensitively detect the user's pressing on the touchpad 10.

[0187] While the pre-compression device applies a preset force to the bottom of the T-screw 2413, in order to maintain the pre-compression state of the T-screw 2413, an adhesive layer 2414 is formed by applying adhesive to the opening 2421, thereby fixing the T-screw 2413 to the opening 2421. The head of the T-screw 2413 can prevent the adhesive layer 2414 from overflowing into the limit switch 101, ensuring the reliable use of the limit switch 101.

[0188] The technical solution of this embodiment eliminates the need to adjust the distance and interaction force between the screw 2411 and the limit switch 101. Instead, the T-shaped screw 2413 and the adhesive layer 2414 can work together to keep the T-shaped screw 2413 and the limit switch 101 in a pre-pressed state that is suitable for the user's pressing action. This allows for more sensitive and convenient detection of the user's pressing action on the touchpad 10, and also ensures the user's pressing feel on the touchpad 10.

[0189] Understandably, Figure 13 and Figure 14 The technical solutions related to the adjusting screw 2411 and T-screw 2413 shown can also be applied to the above. Figures 2 to 12 In any of the embodiments shown, that is Figures 3 to 12 In any of the embodiments shown, the boss where the contact 241 is located can be replaced with an adjusting screw 2411 or a T-screw 2413.

[0190] As an example, in Figure 4 Based on the illustrated embodiment, Figure 15 A schematic exploded view of another touchpad 10 provided in an embodiment of this application is shown.

[0191] like Figure 15 As shown, in the fixed platform 240, Figure 4 In the embodiment shown, the boss of the contact 241 is replaced with an adjusting screw 2411, and a nut 2412 is provided in the central area of ​​the protrusion 242 to facilitate the installation of the adjusting screw 2411 in the protrusion 242.

[0192] In addition, Figure 15In the illustrated embodiment, the touchpad 10 may include, in addition to the various components of the touch component 100 and the support component 200 described above, also include a conductive cloth 300.

[0193] The conductive cloth 300 can be connected to the circuit board 120 in the touch assembly 100 and the main support member 210 in the support assembly 200. The conductive cloth 300 can be used to conduct static electricity generated on the circuit board 120 to the outside of the touch panel 10 through the main support member 210, so as to prevent static electricity from damaging the components in the touch panel 10.

[0194] It is understandable that this conductive cloth 300 can be used in addition to... Figure 15 In addition to the embodiments shown, it can also be applied to the above-described embodiments. Figures 2 to 14 In any of the illustrated embodiments, electrostatic protection is provided for the touchpad 10 of each embodiment.

[0195] This application also provides an electronic device, which includes a housing and a touch panel 10 as described in any of the above-mentioned embodiments. The touch panel is mounted on the housing and is used to provide a press detection function to the electronic device.

[0196] By way of example and not limitation, the electronic devices in this application can be portable or mobile computing devices such as terminal devices, mobile phones, tablet computers and their accessories, keyboards, laptops, desktop computers, gaming devices, in-vehicle electronic devices, or wearable smart devices, as well as other electronic devices such as electronic databases, automobiles, and bank ATMs. The wearable smart devices include devices that are fully functional, large in size, and capable of performing complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as devices that focus on only a specific type of application function and require cooperation with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0197] Optionally, when the electronic device is a laptop, the housing for mounting the touchpad 10 can be the C-shell of the laptop, that is, the housing on the side of the laptop where the keyboard is located.

[0198] It should be noted that, without conflict, the various embodiments and / or technical features described in this application can be arbitrarily combined with each other, and the resulting technical solutions should also fall within the protection scope of this application.

Those skilled in the art can make various improvements and modifications based on the above embodiments, and all such improvements or modifications fall within the protection scope of this application.

[0200] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
