Description

Technical Field

[0001] The present application relates to the technical field of electronic products, and in particular to a pressing device and an electronic device. Background Art

[0002] Electronic devices such as laptops are typically equipped with pressing components such as touchpads, keyboard keys, and mouse buttons, which users can use to operate the electronic devices. The pressing components are often equipped with trigger switches, which users can trigger by pressing the pressing components. However, when users press the pressing components at a distance from the trigger switch, the pressing components may not activate, or require a greater amount of pressure to activate. This results in a low sensitivity of the pressing components. Summary of the Invention

[0003] The embodiments of the present application provide a pressing device and an electronic device for improving the sensitivity of a pressing component, so that a trigger switch can be triggered by pressing the pressing component at any position.

[0004] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0005] In a first aspect, a pressing device is provided, which includes: a pressing component, a linkage component and a bracket; the pressing component includes an initial position and a trigger position, and the pressing component can move between the initial position and the trigger position; the linkage component is arranged on one side of the pressing component, and the linkage component includes a first linkage unit and a second linkage unit arranged along a first direction, and the first linkage unit and the second linkage unit are rotatably connected through a rotating structure; the first linkage unit and the second linkage unit are respectively connected to the pressing component through a connecting structure, so that when the pressing component moves between the initial position and the trigger position, the first linkage unit and the second linkage unit respectively move relative to the pressing component along the first direction and rotate around a rotation axis parallel to the second direction; wherein the first direction is perpendicular to the moving direction of the pressing component, and the second direction is respectively perpendicular to the first direction and the moving direction of the pressing component; the first linkage unit and the second linkage unit are respectively connected to the bracket through a stop structure, and in the first direction, the stop structures are respectively located on the side of the connecting structure away from the rotating structure.

[0006] The pressing device in the embodiment of the present application achieves full-area touch control of the touchpad through a mechanical form, which not only improves the sensitivity of the trigger switch and provides users with a good input experience, but also reduces costs compared to technical solutions that use piezoelectric ceramics or motors to achieve full-area touch control of the touchpad. In addition, the pressing device in the embodiment of the present application, the first linkage unit and the second linkage unit are respectively connected to the bracket through a stop structure. In the first direction, the stop structure is respectively located on the side of the connection structure away from the rotating structure. When the pressing component moves from the initial position to the trigger position, the connection end of the first linkage unit and the second linkage unit can move in a direction away from the pressing component.

[0007] In this way, when the pressing component moves from the initial position to the trigger position, interference between the linkage component and the pressing component can be effectively avoided. On the one hand, the reliability of the pressing device can be improved. On the other hand, there is no need to reserve a gap between the linkage structure and the pressing component, thereby reducing the design difficulty of the pressing device while reducing the size of the pressing device in the thickness direction of the keyboard host, which is conducive to achieving a lightweight design of the keyboard host. In the technical solution where the battery of the electronic device is located below the pressing device, the pressing device in the embodiment of the present application can increase the thickness of the battery without increasing the overall thickness of the keyboard host, thereby improving the battery life of the electronic device.

[0008] In some embodiments, the orthographic projection of the pressing component on the reference plane is the first projection, and the orthographic projection of the stop structure on the reference plane is the second projection, and the second projection does not overlap with the first projection. That is, the second projection is located outside the first projection. In this way, the overlapping of the dimensions of the stop portion and the pressing component in the thickness direction of the keyboard host can be avoided, which is beneficial to reducing the overall thickness of the pressing device, thereby reducing the space occupied by the pressing device in the thickness direction of the keyboard host, and further contributing to the thinness of the keyboard host. In addition, in the technical solution in which the battery is located below the pressing device, the thickness of the battery can be increased without increasing the overall thickness of the keyboard host, thereby increasing the volume of the battery and improving the battery life of the electronic device.

[0009] In some embodiments, the orthographic projection of the pressing component on the reference plane is the first projection, and the orthographic projection of the rotating structure on the reference plane is the third projection, and the third projection does not overlap with the first projection. That is, the third projection is located outside the first projection. In this way, the overlapping of the dimensions of the rotating structure and the pressing component in the thickness direction of the keyboard host can be avoided, which is beneficial to reducing the overall thickness of the pressing device, thereby reducing the space occupied by the pressing device in the thickness direction of the keyboard host, and further contributing to the thinness of the keyboard host. In addition, in the technical solution in which the battery is located below the pressing device, the thickness of the battery can be increased without increasing the overall thickness of the keyboard host, thereby increasing the volume of the battery and improving the battery life of the electronic device.

[0010] In some embodiments, the connection structure includes a first connection portion and a second connection portion. The first connection portion is provided on the pressing component, and the second connection portion is provided on the first linkage unit and the second linkage unit, respectively. A first accommodating space is formed on the first connection portion, and the second connection portion includes a second latching tongue. Part of the first accommodating space is used to accommodate the second latching tongue, so that the second connection portion can move relative to the first connection portion in a first direction and rotate about a rotation axis parallel to a second direction. The structure is simple and easy to process.

[0011] In some embodiments, the first connecting portion includes a first connecting segment and a second connecting segment. One end of the first connecting segment is fixedly connected to the pressing component, and the other end of the first connecting segment extends away from the pressing component. The second connecting segment is connected to the end of the first connecting segment away from the pressing component. The pressing component, the first connecting segment, and the second connecting segment define a first accommodating space. This facilitates forming the first accommodating space on the first connecting portion, avoids the need for grooves in the pressing component, and results in a simple structure that is easy to implement.

[0012] In some embodiments, the first linkage unit and the second linkage unit each include a fixed plate, the fixed plate having a second connecting portion, the second connecting portion further including a through-hole provided on the fixed plate, the second latch connected to the inner wall surface of the through-hole, the second latch having a first sidewall, the first sidewall defining a first latching hole between the inner wall surface of the through-hole, the first connecting segment extending through the first latching hole, and the second latch located between the pressing member and the second connecting segment; wherein the first latching hole has a larger dimension in the first direction than the first connecting segment, and the first accommodating space has a larger dimension in the direction of movement of the pressing member than the second latch in the direction of movement of the pressing member. In this way, when the pressing member moves between the initial position and the trigger position, the second connecting portion is facilitated to move relative to the first connecting portion in the first direction and to rotate about a rotation axis parallel to the second direction, thereby enabling relative movement between the first linkage unit, the second linkage unit, and the pressing member. At the same time, the first accommodation space cooperates with the second latch to limit the rotation angle of the first and second linkage units, thereby limiting the displacement of the pressing component in the direction of movement of the pressing component. The first latch hole cooperates with the first connecting section to limit the displacement of the first and second linkage units in the first direction. In addition, the assembly of the first and second connecting parts is facilitated, reducing the difficulty of assembly.

[0013] In some embodiments, the second latch has a second sidewall surface, the second sidewall surface is disposed adjacent to the first sidewall surface, a second latch hole is defined between the second sidewall surface and the inner wall surface of the through-hole, and the second latch hole is connected to the first latch hole. Thus, by providing the second latch hole and connecting the second latch hole to the first latch hole, the elasticity of the second latch can be increased, facilitating assembly of the second latch into the first accommodating space, and reducing the difficulty of assembly between the first connecting portion and the second connecting portion.

[0014] In some embodiments, the first connecting portion further includes a third connecting segment, the third connecting segment being fixedly connected to the first connecting segment and being passed through the second latch hole. Optionally, the third connecting segment is perpendicular to the first connecting segment. The size of the third connecting segment in the Y-axis direction is substantially equal to the size of the second latch hole in the Y-axis direction. In this way, by cooperating with the third connecting segment and the second latch hole, the first linkage unit can be limited in the Y-axis direction, thereby preventing the first linkage unit from shaking during the movement of the pressing component between the initial position and the trigger position, thereby improving the smoothness of the movement of the pressing component.

[0015] In some embodiments, the first connecting portion further includes a first latch, which defines a first accommodating space; the second latch defines a second accommodating space, a portion of which is used to accommodate the first latch, so that the second connecting portion can move relative to the first connecting portion in a first direction and rotate about a rotation axis parallel to the second direction.

[0024] In some embodiments, the bracket is located on a side of the linkage component away from the pressing component, with the first limiting surface facing the pressing component; or the bracket is located on a side of the linkage component close to the pressing component, with the first limiting surface facing the pressing component.

Another embodiment of the stop structure.

[0026] In some embodiments, the first linkage unit and the second linkage unit each include a fixed plate and two connecting members, the fixed plate being connected to the pressing component, the two connecting members being fixedly connected to one side of the fixed plate and spaced apart in the second direction; the connecting member of the first linkage unit and the connecting member of the second linkage unit are rotatably connected via a rotating structure. This provides a simple structure and easy assembly.

[0027] Optionally, the fixing plate is in the shape of a flat plate, so as to increase the contact area between the first linkage unit, the second linkage unit and the supporting bracket, thereby improving the sensitivity of the pressing device.

[0028] In some embodiments, the linkage component is M-shaped.

[0029] In a possible implementation of the first aspect, a trigger switch is provided on the side surface of the pressing component facing the linkage component, and the trigger switch has an untriggered initial state and a triggered trigger state.

[0030] In a possible implementation of the first aspect, the bracket is arranged on a side of the linkage component away from the pressing component, and a trigger protrusion protruding toward the pressing component is provided on the bracket.

Furthermore, the carrier plate body 1111 is also provided with a second avoidance hole 1111b, which is used to avoid the touchpad assembly 3 mentioned below. A portion of the touchpad assembly 3 can be exposed from the second avoidance hole 1111b to facilitate user operation.

[0104] Please continue reading Figure 4 First avoidance openings 1112a are provided on the first middle plate 1112 at positions corresponding to the plurality of first avoidance holes 1111a. These first avoidance openings 1112a are used to avoid all of the keys 22. Second avoidance openings 1112b are provided on the first middle plate 1112 at positions corresponding to the second avoidance holes 1111b. These second avoidance openings 1112b are used to avoid the touchpad assembly 3. In this embodiment, the second avoidance holes 1111b and the second avoidance openings 1112b form an opening portion for avoiding the touchpad assembly 3.

[0105] To achieve lightweight electronic device 1000, the material of carrier plate body 1111 can be selected from hard plastic, aluminum alloy, etc. The material of first intermediate plate 1112 includes, but is not limited to, hard plastic, metal, or a combination of plastic and metal. The material of first intermediate plate 1112 can be the same as or different from that of carrier plate body 1111.

[0106] It is understandable that, in other embodiments, the supporting plate 111 may not include the first middle plate 1112 , but only include the supporting plate body 1111 .

[0107] See also Figure 4-Figure 5 The first side frame 112 is disposed around the edge of the carrier plate 111. Specifically, in some embodiments, the first side frame 112 is disposed around the edge of the carrier plate body 1111. When the C-shell 11 and the D-shell 12 are aligned, the first side frame 112 is connected between the carrier plate 111 and the D-shell 12.

[0108] Please continue reading Figure 4-Figure 5 The D-shell 12 is flat. The D-shell 12 and the carrier plate 111 are disposed opposite each other in the Z-axis direction. "The D-shell 12 and the carrier plate 111 are disposed opposite each other" means that the two can be parallel or have a certain angle between them, for example, between 0 and 45 degrees.

[0109] The keyboard 2 is used to input commands and data. The keyboard 2 can be fixed to the carrier board 111. For details, please refer to Figure 3 The keyboard 2 includes a fixed plate 21 and a plurality of keys 22 connected to the fixed plate 21. The fixed plate 21 is generally in the shape of a rectangular flat plate. The fixed plate 21 is fixed to the carrier plate 111. Specifically, the fixed plate 21 can be fixed to the inner surface of the carrier plate body 1111. The key 22 extends out of the C shell 11 through the first avoidance hole 1111a corresponding thereto. The key 22 can move relative to the fixed plate 21 in the thickness direction of the fixed plate 21 (i.e., in the Z-axis direction) to trigger the key 22, and then instructions or data can be input through the key 22.

[0110] The motherboard 4 is used to integrate the control chip. The motherboard 4 can be electrically connected to the keyboard 2 and touchpad to receive information output by the keyboard 2 and touchpad. The motherboard 4 can also be electrically connected to the display 100 to control the display of images or videos. The motherboard 4 can be fixed to the first middle plate 1112 by means of threaded connection, snap-on connection, welding, etc. Of course, it is understood that in other embodiments, the motherboard 4 can also be fixed to the directly fixed support plate body 1111, the first side frame 112, or the D-shell 12 by means of threaded connection, snap-on connection, welding, etc.

[0111] The battery 5 is used to provide power to the electronic device 1000 when the electronic device 1000 is not connected to an external power source. The battery 5 is fixed in the internal accommodation space of the housing 1. Figure 5 The battery 5 can be fixed to the surface of the D-shell 12 facing the carrier plate 111 by means of threaded connection, snap connection, etc. For example, the battery 5 can be arranged below the touchpad assembly 3. In this way, the battery 5 can be hidden within the shell 1, which is beneficial to improving the appearance of the electronic device 1000.

[0112] The touchpad assembly 3 includes a touchpad 31. The touchpad 31 can replace a mouse to control the electronic device 1000, or can work in conjunction with a mouse to improve the portability of the electronic device 1000. Specifically, a user can use a finger or other touch action (including swiping, clicking, etc.) on the surface of the touchpad 31 to control the movement of the cursor on the display 100, thereby performing mouse operations such as "cursor navigation," "selection," and "confirmation."

[0113] See also Figure 6-Figure 7 , Figure 6A three-dimensional diagram of a touch panel 31 provided in some embodiments of the present application, Figure 7 for Figure 6 A cross-sectional view of the touchpad 31 taken along line CC is shown. The touchpad 31 includes a touch substrate 311 and a circuit board 312. The touch substrate 311 is configured to receive user touch and press operations. The touch substrate 311 is fixedly connected to a side surface of the circuit board 312. Exemplarily, the touch substrate 311 is fixedly connected to the circuit board 312 via adhesive.

[0114] For details, please refer to Figure 6-Figure 7 The touch substrate 311 is plate-shaped. Exemplarily, the touch substrate 311 is rectangular. The length of the touch substrate 311 is parallel to the X-axis, the width of the touch substrate 311 is parallel to the Y-axis, and the thickness of the touch substrate 311 is parallel to the Z-axis. The touch substrate 311 has a touch surface 311a, which is located on the side of the touch substrate 311 facing away from the circuit board 312. The touch surface 311a constitutes part of the outer surface of the keyboard host 200 and supports user operations such as clicking and sliding.

[0115] In some embodiments, the touch substrate 311 is a mylar sheet. In other embodiments, the touch substrate 311 may also be a glass sheet.

[0116] The circuit board 312 carries electronic components and circuits for transmitting and processing touch signals, pressure signals, and vibration signals. The shape of the circuit board 312 matches the shape of the touch substrate 311. For example, the circuit board 312 is in the shape of a rectangular plate.

[0117] See also Figure 7 A trigger switch 3121 is provided on the side of the circuit board 312 facing away from the touch substrate 311. The trigger switch 3121 can be provided in the middle of the circuit board 312. Specifically, the trigger switch 3121 protrudes from the surface of the circuit board 312 facing away from the touch substrate 311. The trigger switch 3121 can be triggered when squeezed.

[0118] Optionally, the trigger switch 3121 is an elastic switch. That is, the trigger switch 3121 can be elastically deformed. Exemplarily, the trigger switch 3121 is a metal spring that generates elastic force when squeezed and automatically returns to its original shape when the pressure is released.

[0119] Specifically, the touchpad 31 includes an initial position and a trigger position, and the touchpad 31 can move between the initial position and the trigger position, so that the trigger switch 3121 switches between an initial state (not triggered) and a triggered state. Specifically, when the touchpad 31 is in the initial position, the trigger switch 3121 is in the initial state, and when the touchpad 31 is in the trigger position, the trigger switch 3121 is in the triggered state. When the trigger switch 3121 is triggered, the user can control the electronic device 1000 via the touchpad 31.

[0120] The movement direction of the touchpad 31 is parallel to the Z-axis. The "initial position of the touchpad 31" refers to the position of the touchpad 31 when the touchpad 31 is not pressed. The "trigger position of the touchpad 31" refers to the position of the touchpad 31 when the touchpad 31 is pressed and moved downward until the trigger switch 3121 is in the triggered state.

[0121] In order to facilitate the user to trigger the trigger switch 3121, a trigger bump 340 corresponding to the trigger switch 3121 may be provided in the keyboard host 200. Figure 8 , Figure 8 for Figure 5 Enlarged view of area A in the middle. When a user presses the touchpad 31 and applies downward pressure F, the touchpad 31 can move from its initial position toward the trigger position. When the touchpad 31 moves downward to the trigger position, the trigger switch 3121 is squeezed by the trigger bump 340 and triggered, causing elastic deformation of the trigger switch 3121. When the user removes the pressure F on the touchpad 31, the trigger switch 3121 returns to its original shape. The elastic force of the trigger switch 3121 allows the touchpad 31 to move upward to its initial position.

[0122] It is understandable that, in other embodiments, the triggering protrusion 340 may also be configured as an elastic member. In this case, the triggering switch 3121 may be an elastic switch or a non-elastic switch.

[0123] The touchpad assembly 3 in the above embodiment has a simple structure, but since the trigger switch 3121 is located in the middle area of ​​the touchpad 31, when the user presses the edge of the touchpad 31, it is easy for the touchpad 31 to not be pressed, or a large pressing force is required to press the touchpad 31, and the trigger switch 3121 cannot be triggered, resulting in low sensitivity of the trigger switch 3121, which affects the user's input experience.

[0124] In order to solve the above technical problems, pressing any position of the touch panel 31 can trigger the trigger switch 3121. Figure 9-10 , Figure 9 A three-dimensional diagram of a touch panel assembly 3 provided in some other embodiments of the present application, Figure 10 for Figure 9 The touch panel assembly 3 shown in FIG. Figure 6 In addition to the touch panel 31 , the touch panel 31 further includes a support bracket 32 ​​, a linkage component 33 and a bracket 34 .

[0125] It should be noted that Figure 9-10 Only some components of the touch panel assembly 3 are shown schematically, and the actual shapes, sizes, positions and structures of these components are not affected by the present invention. Figure 9-10 and the accompanying drawings below. Figure 9 The coordinate system in Figure 2 The coordinate system in is represented as the same coordinate system. That is, Figure 9 The various components of the touch panel assembly 3 are Figure 9 The orientation relationship in the coordinate system shown is the same as when the touch panel assembly 3 is applied to Figure 2 When the keyboard host 200 is shown, its various components are Figure 2 The orientation relationships in the coordinate system shown are the same. Furthermore, when describing the shapes of the various components of the touchpad assembly 3 below as "rectangular" or "square," these generally represent approximate shapes; adjacent edges may or may not have rounded corners. Furthermore, when describing the orientation relationships of the various components of the touchpad assembly 3 below, terms such as "parallel," "perpendicular," "directed in the same direction," "directed in the same direction," and "directed in opposite directions" all represent approximate orientations within which a certain tolerance is permitted. For example, a tolerance of ±10° is permitted.

[0126] The support bracket 32 ​​is used to support the touch panel 31 and to connect the linkage component 33. Figure 9 The touchpad 31 is fixedly connected to the support bracket 32. When the user presses down on the touchpad 31, the support bracket 32 ​​moves along with the touchpad 31. In this embodiment, the touchpad 31 and the support bracket 32 ​​are both part of the pressing component. That is, in this embodiment, the pressing component includes the touchpad 31 and the support bracket 32.

[0127] See also Figure 9-10 The linkage component 33 is disposed on one side of the support bracket 32. Specifically, the linkage component 33 is disposed on the side of the support bracket 32 ​​facing away from the touchpad 31. The linkage component 33 includes a first linkage unit 33a and a second linkage unit 33b. The first linkage unit 33a and the second linkage unit 33b are arranged in a first direction. The first direction is perpendicular to the movement direction of the touchpad 31. In other words, the first direction is perpendicular to the Z-axis.

[0128] In some embodiments, the first direction is parallel to the length of the keyboard host 200. That is, the first direction is parallel to the X-axis. This allows full utilization of the space along the length of the keyboard host 200 (i.e., the X-axis), reducing the space occupied by the linkage component 33 along the width of the keyboard host 200 (i.e., the Y-axis), thereby reducing the gap between the touchpad 31 and the edge of the carrier plate 1111. This in turn helps reduce the width of the keyboard host 200, thereby achieving a miniaturized design for the keyboard host 200.

[0129] It is understood that in other embodiments, the first direction may also be parallel to the width direction of the keyboard host 200. Alternatively, the first direction may also be parallel to the extension direction of the diagonal line of the keyboard host 200, as long as the first direction is perpendicular to the movement direction of the touchpad 31.

[0130] For ease of description, the following description will be made by taking the case where the first linkage unit 33a is located in the negative direction of the X-axis and the second linkage unit 33b is located in the positive direction of the X-axis, that is, the case where the first linkage unit 33a is located to the left of the second linkage unit 33b. The direction "left" described in this application refers to the direction of the user's left hand side when the user uses the electronic device 1000, and correspondingly, the direction "right" described in this application refers to the direction of the user's left hand side when the user uses the electronic device 1000. In addition, it should be noted that in the description of this application, the terms "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on this application.

[0131] See also Figure 9 The first linkage unit 33a and the second linkage unit 33b are rotatably connected via a rotating structure 35. Figure 10 The first linkage unit 33a includes a first end 331 , and the second linkage unit 33b includes a second end 332 . The first end 331 and the second end 332 are rotatably connected via a rotating structure 35 .

[0132] See also Figure 9 Combined with Figure 11 , Figure 11 for Figure 9 The touchpad assembly 3 is shown in a cross-sectional view taken along line DD. The first linkage unit 33a and the second linkage unit 33b are each connected to the support bracket 32 ​​via a connecting structure 36. When the touchpad 31 and the support bracket 32 ​​move between the initial position and the trigger position, the first linkage unit 33a and the second linkage unit 33b rotate about a rotation axis parallel to the second direction, and the first linkage unit 33a and the second linkage unit 33b move in the first direction relative to the support bracket 32.

[0133] The second direction is perpendicular to the first direction and perpendicular to the moving direction of the pressing component. Exemplarily, the second direction is parallel to the Y axis.

[0134] It is understood that in other embodiments, the pressing component may include only the touchpad 31 without the support bracket 32. In this embodiment, the first linkage unit 33a may be connected to the touchpad 31 via the connection structure 36, and the second linkage unit 33b may be connected to the touchpad 31 via the connection structure 36.

[0135] The bracket 34 is provided on one side of the linkage component 33. The touchpad assembly 3 can be assembled into the keyboard host 200 with the help of the bracket 34. Specifically, the bracket 34 can be fixedly connected to the C shell 11 of the keyboard host 200. The touchpad 31 and the support bracket 32 ​​can move between the initial position and the trigger position relative to the bracket 34. For example, please refer to Figure 11 In this embodiment, the bracket 34 is provided on a side of the linkage component 33 away from the touch panel 31 .

[0136] See also Figure 9 Combined with Figure 11 The first linkage unit 33a and the second linkage unit 33b are respectively connected to the bracket 34 via a stop structure 37. In the first direction, the stop structures 37 are respectively located on the side of the connection structure 36 away from the rotation structure 35. The stop structures 37 are used to limit the first linkage unit 33a and the second linkage unit 33b in the moving direction of the pressing component (i.e., the Z-axis direction).

[0137] For the convenience of description, the stop structure 37 for connecting the first linkage unit 33a and the bracket 34 is referred to as the first stop structure, the stop structure 37 for connecting the second linkage unit 33b and the bracket 34 is referred to as the second stop structure, the connection structure 36 for connecting the first linkage unit 33a and the support bracket 32 ​​is referred to as the first connection structure, and the connection structure 36 for connecting the second linkage unit 33b and the support bracket 32 ​​is referred to as the second connection structure. Figure 11 The first stop structure is located on a side of the first connecting structure away from the rotating structure 35, and the second stop structure is located on a side of the second stop structure away from the rotating structure 35. The first stop structure is used to limit the first linkage unit 33a in the Z-axis direction. The second stop structure is used to limit the second linkage unit 33b in the Z-axis direction.

[0138] When the touch pad 31 and the support bracket 32 ​​move between the initial position and the trigger position, the first linkage unit 33a and the second linkage unit 33b can both rotate relative to the bracket 34 around a rotation axis parallel to the second direction, and the first linkage unit 33a and the second linkage unit 33b can both move relative to the bracket 34 in the first direction.

[0139] Refer to the following Figure 12-13 The movement process of the pressing component and the linkage component 33 in the touch panel assembly 3 of this embodiment is described.

[0140] See also Figure 12 , Figure 12 for Figure 11 The figure shows a simplified schematic diagram of the touch pad 31 of the touch pad assembly 3 moving from an initial position to a trigger position. Figure 12 The touch panel 31 and the linkage component 33 shown by the solid line are in the initial position, and the touch panel 31 and the linkage component 33 shown by the dotted line are in the trigger position. Figure 12 The support bracket 32 ​​is not shown. For ease of description, the position where the first linkage unit 33a is connected to the bracket 34 is referred to as the "first connection position P1", the position where the first linkage unit 33a is connected to the pressing component is referred to as the "second connection position P2", the position where the second linkage unit 33b is connected to the bracket 34 is referred to as the "third connection position P3", and the position where the second linkage unit 33b is connected to the pressing component is referred to as the "fourth connection position P4".

[0141] See also Figure 12 Combined with Figure 11 Since the first linkage unit 33a and the second linkage unit 33b are connected to the bracket 34 via the first stop structure 37a and the second stop structure 37b, respectively, in the first direction, the first stop structure 37a is located on the side of the first connection structure 36a away from the rotation structure 35, and the second stop structure 37b is located on the side of the second connection structure 36b away from the rotation structure 35. The first stop structure 37a is used to limit the first linkage unit 33a in the Z-axis direction. The second stop structure 37b is used to limit the second linkage unit 33b in the Z-axis direction. When the user presses downward on the left edge of the touchpad 31, the left edge of the touchpad 31 moves downward, and the first linkage unit 33a moves downward with the touchpad 31. As a result, the first linkage unit 33a rotates clockwise relative to the touchpad 31 and the bracket 34 with the first connection position P1 as the rotation fulcrum. In other words, the first end 331 of the first linkage unit 33a rotates downward relative to the first connection position P1.

[0142] See also Figure 12Because the second end 332 of the second linkage unit 33b is rotatably connected to the first end 331 of the first linkage unit 33a, when the first linkage unit 33a rotates clockwise relative to the touchpad 31 and bracket 34 with the first connection position P1 as the rotation fulcrum, the second connection position P2 moves along the first direction relative to the touchpad 31 toward the second linkage unit 33b, while the first connection position P1 moves along the first direction relative to the bracket 34 away from the second linkage unit 33b. Furthermore, when the first end 331 of the first linkage unit 33a rotates downward relative to the first connection position P1, the first linkage unit 33a can drive the second end 332 of the second linkage unit 33b to move downward.

[0143] Please continue reading Figure 12 Combined with Figure 11 Because the second linkage unit 33b is connected to the bracket 34 via the second stop structure 37b, and in the first direction, the second stop structure 37b is located on the side of the second connection structure 36b away from the rotating structure 35, when the second end 332 of the second linkage unit 33b moves downward, the second linkage unit 33b can rotate counterclockwise relative to the touchpad 31 and the bracket 34 with the third connection position P3 as the rotation fulcrum. At the same time, the fourth connection position P4 moves relative to the touchpad 31 in the first direction toward the first linkage unit 33a, and the third connection position P3 moves in the first direction away from the first linkage unit 33a. As a result, the right edge area of ​​the touchpad 31 can be driven downward by the second linkage unit 33b.

[0144] In this way, when the user presses down on the left edge area of ​​the touchpad 31, the right edge area of ​​the touchpad 31 can also move downward, so that the touchpad 31 can move downward stably as a whole, preventing the touchpad 31 from tilting up, and then can smoothly trigger the trigger switch 3121, thereby improving the sensitivity of the trigger switch 3121.

[0145] In some embodiments, the first linkage unit 33a and the second linkage unit 33b are symmetrically arranged about the YZ plane. In this case, when the touch panel 31 moves between the initial position and the trigger position, the movement of the first linkage unit 33a and the movement of the second linkage unit 33b are symmetrical about their symmetry planes.

[0146] Please continue reading Figure 12Similarly, when the user presses down on the right edge area of ​​the touchpad 31, the right edge area of ​​the touchpad 31 moves downward, and the second linkage unit 33b moves downward with the touchpad 31. At the same time, the second linkage unit 33b rotates counterclockwise relative to the touchpad 31 and the bracket 34 with the third connection position P3 as the rotation fulcrum. The fourth connection position P4 moves relative to the touchpad 31 along the first direction toward the first linkage unit 33a, and the third connection position P3 moves relative to the bracket 34 along the first direction toward away from the first linkage unit 33a.

[0147] Furthermore, since the second end 332 of the second linkage unit 33b is rotatably connected to the first end 331 of the first linkage unit 33a, the second end 332 of the second linkage unit 33b rotates downward relative to the third connection position P3, the second linkage unit 33b can drive the first end 331 of the first linkage unit 33a to move downward, and the second connection position P2 moves relative to the touch pad 31 along the first direction toward the direction close to the second linkage unit 33b, and the first connection position P1 moves along the first direction toward the direction away from the second linkage unit 33b, thereby driving the left edge area of ​​the touch pad 31 to move downward through the first linkage unit 33a.

[0148] In this way, when the user presses down on the right edge area of ​​the touchpad 31, the left edge area of ​​the touchpad 31 can also move downward, so that the touchpad 31 can move downward stably as a whole, preventing the touchpad 31 from tilting up, and then can smoothly trigger the trigger switch 3121, thereby improving the sensitivity of the trigger switch 3121.

[0149] Therefore, the touchpad assembly 3 in the embodiment of the present application, by setting a linkage component 33, can drive the first linkage unit 33a and the second linkage unit 33b to move downward when any position of the touch surface 331a of the touchpad 31 is pressed through one of the first linkage unit 33a and the second linkage unit 33b, so that the touchpad 31 can move downward stably as a whole, avoiding the touchpad 31 from tilting, and then can smoothly trigger the trigger switch 3121, realizing full-area touch control of the touchpad 31 in a mechanical form, which not only improves the sensitivity of the trigger switch 3121 and brings a good input experience to the user, but also reduces the cost compared with the technical solution of using piezoelectric ceramics or motors to realize full-area touch control of the touchpad 31.

[0150] Furthermore, in the touchpad assembly 3 of the embodiment of the present application, the first linkage unit 33a and the second linkage unit are connected to the bracket 34 via a first stop structure 37a and a second stop structure 37b, respectively. In the first direction, the first stop structure 37a is located on a side of the first connection structure 36a away from the rotation structure 35, and the second stop structure 37b is located on a side of the second connection structure 36b away from the rotation structure 35. When the touchpad 31 moves from the initial position to the trigger position, the first end 331 of the first linkage unit 33a can rotate relative to the position where the first linkage unit 33a is connected to the bracket 34, away from the touchpad 31, and the second end 332 of the second linkage unit 33b can rotate relative to the position where the second linkage unit 33b is connected to the bracket 34, away from the touchpad 31.

[0151] In this way, when the touchpad 31 moves from the initial position to the trigger position, the interference between the linkage component 33 and the touchpad 31 can be effectively avoided. On the one hand, the reliability of the touchpad assembly 3 can be improved. On the other hand, there is no need to reserve a gap between the connection position of the first linkage unit 33a and the second linkage unit 33b and the touchpad 31, thereby reducing the design difficulty of the touchpad assembly 3 while reducing the size of the touchpad assembly 3 in the thickness direction of the keyboard host 200, which is conducive to realizing a lightweight design of the keyboard host 200. For the technical solution in which the battery 55 of the electronic device 1000 is located below the touchpad assembly 3, the touchpad assembly 3 in the embodiment of the present application can increase the thickness of the battery 55 without increasing the overall thickness of the keyboard host 200, thereby improving the battery life of the electronic device 1000.

[0152] See also Figure 13 , Figure 13 for Figure 11 The simplified schematic diagram of the touch pad 31 of the touch pad assembly 3 moving from the trigger position to the initial position is shown. Figure 13 The touch panel 31 and the linkage component 33 shown by the solid line are in the trigger position, and the touch panel 31 and the linkage component 33 shown by the dotted line are in the initial position. Figure 13 The support bracket 32 ​​is not shown.

[0153] After the touch pad 31 moves to the trigger position, the trigger switch 3121 is triggered and elastically deforms. When the user removes the pressing force on the touch pad 31, the trigger switch 3121 recovers its deformation, and the touch pad 31 moves upward toward the initial position under the action of the elastic force of the trigger switch 3121. The first linkage unit 33a and the second linkage unit 33b move upward under the drive of the touch pad 31.

[0154] See also Figure 11 Combined with Figure 13Because the first stop structure 37a limits the movement of the first linkage unit 33a in the Z-axis direction, and the second stop structure 37b limits the movement of the second linkage unit 33b in the Z-axis direction, when the first linkage unit 33a and the second linkage unit 33b move upward, the first linkage unit 33a rotates counterclockwise relative to the touch pad 31 and the bracket 34 with the first connection position P1 as the rotation fulcrum, and the second connection position P2 moves relative to the touch pad 31 in the first direction toward the direction away from the second linkage unit 33b, and the first connection position P1 moves relative to the bracket 34 in the first direction toward the direction close to the second linkage unit 33b. At the same time, the second linkage unit 33b rotates clockwise relative to the touch pad 31 and the bracket 34 with the third connection position P3 as the rotation fulcrum, and the fourth connection position P4 moves relative to the touch pad 31 in the first direction toward the direction away from the first linkage unit 33a, and the third connection position P3 moves relative to the bracket 34 in the first direction toward the direction close to the first linkage unit 33a. In this way, through the cooperation between the first linkage unit 33a and the second linkage unit 33b, the touch panel 31 can move smoothly from the trigger position to the initial position.

[0155] The following describes the specific structures of the support bracket 32, the linkage component 33 and the bracket 34 in the touch panel assembly 3 provided in some embodiments of the present application.

[0156] See also Figure 14 , Figure 14 for Figure 10 The support bracket 32 ​​in the touchpad assembly 3 is shown in a three-dimensional view. The support bracket 32 ​​is a frame structure. The outer contour of the support bracket 32 ​​is adapted to the shape of the touchpad 31. For example, the support bracket 32 ​​is a rectangular frame structure.

[0157] For details, please refer to Figure 14 The support bracket 32 ​​includes a first short side 321 and a second short side 322 relative to each other, and a first long side 323 and a second long side 324 relative to each other. The extension direction of the first long side 323 and the second long side 324 is parallel to the X-axis, and the extension direction of the first short side 321 and the second short side 322 is parallel to the Y-axis. The support bracket 32 ​​is formed by the first short side 321, the first long side 323, the second short side 322, and the second long side 324 being connected and enclosed in sequence. A through hole 325 is defined between the first short side 321, the first long side 323, the second short side 322, and the second long side 324. The through hole 325 can be a rectangular hole, a square hole, a circular hole, an elliptical hole, etc.

[0158] Please continue reading Figure 14 The support bracket 32 ​​includes a top surface 326 and a bottom surface 327 that are opposite to each other in the thickness direction. The top surface 326 is used to be fixedly connected to the touch panel 31. The thickness direction of the support bracket 32 ​​is parallel to the Z axis.

[0159] The support bracket 32 ​​can be an integral structural member, or can be formed by assembling multiple parts by bonding, clamping, threading, etc.

[0160] The support bracket 32 ​​serves to enhance the rigidity of the touchpad 31, thereby reducing deformation and collapse caused by a user pressing the touchpad 31. It is understood that the support bracket 32 ​​may be omitted if the touchpad 31 is sufficiently rigid. Furthermore, the support bracket 32 ​​allows the pressing component to be connected to the linkage component 33 via the support bracket 32, effectively protecting the touchpad 31 from damage and improving the reliability of the touchpad assembly 3.

[0161] See also Figure 15-16 , Figure 15 for Figure 10 The schematic diagram of the assembly of the support bracket 32 ​​and the touch pad 31 in the touch pad assembly 3 is shown. Figure 16 for Figure 15 The assembly diagram shown is a cross-sectional view at line EE.

[0162] Specifically, the top surface 326 of the support bracket 32 ​​is fixedly connected to the surface of the circuit board 312 facing away from the touch substrate 311. Exemplarily, the top surface 326 of the support bracket 32 ​​is adhesively connected to the surface of the circuit board 312 facing away from the touch substrate 311.

[0163] See also Figure 16 The trigger switch 3121 on the touchpad 31 is directly opposite the through hole 325. Thus, by configuring the support bracket 32 ​​as a frame structure, the through hole 325 can be formed on the support bracket 32. This can prevent the support bracket 32 ​​from interfering with the trigger switch 3121 while ensuring the support effect of the support bracket 32. Furthermore, it can reduce the material used for the support bracket 32 ​​while ensuring the support effect of the support bracket 32, thereby reducing the weight of the support bracket 32 ​​and thus reducing the overall weight of the touchpad assembly 3.

[0164] Please continue reading Figure 16 The area enclosed by the outer contour of the support bracket 32 ​​is larger than the area of ​​the touchpad 31. In other words, the orthographic projection of the touchpad 31 on the plane where the support bracket 32 ​​lies lies within the outer contour of the support bracket 32. This ensures the support effect of the support bracket 32 ​​and prevents the edge of the touchpad 31 from warping.

[0165] Because the structural strength of the support bracket 32 ​​directly determines its support effectiveness, the thickness of the support bracket 32 ​​can be increased to ensure its structural strength. However, this will increase the overall thickness of the touchpad assembly 3. To avoid this problem, the support bracket 32 ​​can be made of a material with high rigidity to achieve a balance between structural strength and thickness. In some embodiments, the support bracket 32 ​​is a metal member. For example, the support bracket 32 ​​can be made of stainless steel, aluminum, or the like.

[0166] See also Figure 17-18 , Figure 17 for Figure 10 A three-dimensional diagram of the linkage component 33 in the touch panel assembly 3 is shown. Figure 18 for Figure 17 An exploded view of the linkage component 33 is shown.

[0167] The first linkage unit 33a and the second linkage unit 33b each include a fixing plate 333 and two connecting members 334. In this embodiment, the structure of the second linkage unit 33b is identical to that of the first linkage unit 33a, and the first and second linkage units 33a and 33b are symmetrically arranged about the YZ plane. The fixing plate 333 is used to connect to the support bracket 32. The fixing plate 333 is flat. This increases the contact area between the first and second linkage units 33a and 33b and the support bracket 32, thereby improving the sensitivity of the touchpad assembly 3.

[0168] Illustratively, the fixing plate 333 is rectangular. The thickness of the fixing plate 333 is parallel to the Z axis. In other words, the fixing plate 333 is formed as a flat plate structure parallel to the touchpad 31. This facilitates the connection between the first linkage unit 33a and the second linkage unit 33b and the support bracket 32, reducing the difficulty of assembling the touchpad assembly 3 and improving assembly efficiency.

[0169] It is understandable that, in other embodiments, the thickness direction of the fixing plate 333 may not be parallel to the touch panel 31. In other words, the fixing plate 333 is an inclined plate-shaped structure.

[0170] See also Figure 17-18 The connecting members 334 are elongated. Both connecting members 334 are fixed to one side of the fixed plate 333 and are spaced apart in the second direction. Specifically, both connecting members 334 of the first linkage unit 33a are fixedly connected to the side of the fixed plate 333 of the first linkage unit 33a that is close to the second linkage unit 33b. Both connecting members 334 of the second linkage unit 33b are fixedly connected to the side of the fixed plate 333 of the second linkage unit 33b that is close to the first linkage unit 33a.

[0171] The connecting member 334 of the first linkage unit 33 a and the connecting member 334 of the second linkage unit 33 b are rotatably connected via a rotating structure 35 .

[0172] In some embodiments, see Figure 19 , Figure 19 for Figure 17 An enlarged view of the F region in the stereoscopic diagram is shown. The rotating structure 35 includes a first sleeve 351, a second sleeve 352, and a shaft core 353. The first sleeve 351 is fixedly connected to the connecting member 334 of the first linkage unit 33a, and the second sleeve 352 is fixedly connected to the connecting member 334 of the second linkage unit 33b. A first axial hole is formed in the first sleeve 351, and a second axial hole is formed in the second sleeve 352, the second axial hole corresponding to the first axial hole. The shaft core 353 is inserted into the first and second axial holes. In this way, a rotational connection can be achieved between the connecting member 334 of the first linkage unit 33a and the connecting member 334 of the second linkage unit 33b, and the structure is simple and easy to assemble.

[0173] In some embodiments, the second sleeve 352 may be located on a side of the first sleeve 351 away from the central axis of the linkage component 33. In other embodiments, the second sleeve 352 may also be located on a side of the first sleeve 351 close to the central axis of the linkage component 33.

[0174] Optionally, the first sleeve 351 and the connecting piece 334 of the first linkage unit 33a are an integrated structure. The second sleeve 352 and the connecting piece 334 of the second linkage unit 33b are an integrated structure.

[0175] In this embodiment, by providing a first shaft sleeve 351 on the connecting member 334, providing a second shaft sleeve 352 on the second connecting member 3323, and providing a first shaft hole for cooperating with the shaft core 353 on the first shaft sleeve 351, and providing a second shaft hole for cooperating with the shaft core 353 on the second shaft sleeve 352, it is possible to avoid directly drilling a hole in the connecting member 334, thereby improving the structural strength of the connecting member 334. On the other hand, it is possible to make the structure of the first linkage unit 33a and the structure of the second linkage unit 33b the same, thereby simplifying the structure of the linkage component 33. During the processing, a linkage unit is processed, which can be used as both the first linkage unit 33a and the second linkage unit 33b, thereby greatly reducing the processing cost.

[0176] It is understood that the structure of the rotating structure 35 in this embodiment is not limited to this. For example, please refer to Figure 20 , Figure 20Schematic diagrams illustrating the connection between the connector 334 of the first linkage unit 33a and the connector 334 of the second linkage unit 33b in other embodiments of the present application. The rotation structure 35 is a flexible member. This flexible member is connected between the connector 334 of the first linkage unit 33a and the connector 334 of the second linkage unit 33b. The thickness of the flexible member is less than that of the connector 334. Thus, by configuring the rotation structure 35 as a flexible member, the structure of the linkage component 33 can be simplified and the space occupied by the rotation structure 35 can be reduced, thereby reducing the overall thickness of the touchpad assembly 3 and achieving a lightweight and thin design for the electronic device 1000.

[0177] It is understandable that the rotating structure 35 can also be other structures, as long as the connecting member 334 of the first linkage unit 33a and the connecting member 334 of the second linkage unit 33b can be rotatably connected through the rotating structure 35, this application does not make any specific limitations on the structure of the rotating structure 35.

[0178] To facilitate connection between the first linkage unit 331 and the second linkage unit 332 and the support bracket 32, the first linkage unit 331 and the second linkage unit 33b are each connected to the support bracket 32 ​​via a connecting structure 36. The connecting structure 36 includes a first connecting portion 361 and a second connecting portion 362. The first connecting portion 361 is provided on the support bracket 32, and the first linkage unit 33a and the second linkage unit 33b are each provided with a second connecting portion 362.

[0179] See also Figure 21 , Figure 21 for Figure 14 Another perspective view of the support bracket 32 ​​is shown. Specifically, Figure 21 The figure is a three-dimensional view of the support bracket 32 ​​viewed from the bottom surface 327 toward the top surface 326. A first connecting portion 361 is provided on the bottom surface 327 of the support bracket 32. Specifically, two first connecting portions 361 are provided on the bottom surface 327 corresponding to the first short side 321. The two first connecting portions 361 are used to connect to the second connecting portion 362 on the first linkage unit 33a. The two first connecting portions 361 on the first short side 321 are symmetrically arranged about the XZ plane. It is understood that in other embodiments, the number of first connecting portions 361 on the first short side 321 may be one, three, four, or other plurality.

[0180] Two first connecting portions 361 are provided on the bottom surface 327 corresponding to the second short side 322. The two first connecting portions 361 are configured to connect to the second connecting portion 362 on the second linkage unit 33b. The two first connecting portions 361 on the first short side 321 and the two first connecting portions 361 on the second short side 322 are symmetrically arranged about the YZ plane.

[0181] See also Figure 22 , Figure 22 for Figure 21 An enlarged view of the D region in the stereoscopic view is shown. The first connecting portion 361 includes a first connecting segment 3611, a second connecting segment 3612, and a third connecting segment 3613. The first connecting segment 3611 is fixedly connected to the bottom surface 327 of the support bracket 32. The first connecting segment 3611 is flat. Specifically, one end of the first connecting segment 3611 is fixedly connected to the bottom surface 327, and the other end of the first connecting segment 3611 extends away from the top surface 326.

[0182] In some embodiments, the first connecting section 3611 is perpendicular to the bottom surface 327. For example, the first connecting section 3611 is in the shape of a rectangular plate. The length of the first connecting section 3611 can be parallel to the Y-axis, and the width of the first connecting section 3611 can be parallel to the Z-axis. In other embodiments, the length of the first connecting section 3611 can also be parallel to the X-axis.

[0183] In other embodiments, the first connecting section 3611 may be in the shape of a flat plate but not perpendicular to the bottom surface 327. Alternatively, the first connecting section 3611 may also be in the shape of an arc-shaped plate.

[0184] See also Figure 22 The second connecting section 3612 is fixedly connected to one end of the first connecting section 3611 away from the bottom surface 327 of the support bracket 32. The second connecting section 3612 is in the shape of a flat plate. Specifically, one end of the second connecting section 3612 is connected to the first connecting section 3611, and the other end of the second connecting section 3612 extends in a direction away from the first connecting section 3611. A first accommodating space 3614 is defined between the bottom surface 327 of the support bracket 32, the second connecting section 3612, and the first connecting section 3611. Optionally, the second connecting section 3612 is parallel to the bottom surface 327. A smooth transition can be achieved between the second connecting section 3612 and the first connecting section 3611.

[0185] In other embodiments, the second connecting section 3612 may be in the shape of a flat plate but parallel to the bottom surface 327. Alternatively, in other embodiments, the first connecting section 3611 may also be in the shape of an arc-shaped plate.

[0186] Please continue reading Figure 22The third connecting segment 3613 is provided at one end of the length direction of the first connecting segment 3611. The third connecting segment 3613 and the first connecting segment 3611 form an L-shaped structure. Exemplarily, the third connecting segment 3613 is provided on one side of the first connecting segment 3611 in the Y-axis direction. The third connecting segment 3613 is fixedly connected to the first connecting segment 3611, and further, the third connecting segment 3613 is fixedly connected to the second connecting segment 3612. The third connecting segment 3613 is in the shape of a flat plate. Exemplarily, the third connecting segment 3613 is in the shape of a rectangular plate. The length direction of the third connecting segment 3613 is parallel to the X-axis, and the width direction of the third connecting segment 3613 is parallel to the Z-axis. Optionally, the third connecting segment 3613 is perpendicular to the first connecting segment 3611, and the third connecting segment 3613 is perpendicular to the second connecting segment 3612.

[0187] In some embodiments, the first connecting portion 361 is an integral structural member, that is, the first connecting portion 361 is integrally formed.

[0188] Furthermore, the first connecting portion 361 and the support bracket 32 ​​are integrally formed. That is, the first connecting portion 361 and the support bracket 32 ​​are integrally formed. This improves the connection strength between the first connecting portion 361 and the support bracket 32, simplifies the manufacturing process of the support bracket 32, and reduces costs.

[0189] Please return to Figure 17-18 The first linkage unit 33a and the second linkage unit 33b are each provided with a second connection portion 362 for connecting to the first connection portion 361. The second connection portion 362 is provided on the fixed plate 333. Specifically, the fixed plate 333 of the first linkage unit 33a is provided with two second connection portions 362. The two second connection portions 362 have the same structure and are symmetrical about the XZ plane.

[0190] The fixing plate 333 of the second linkage unit 33b is provided with two second connection parts 362. The second connection parts 362 on the second linkage unit 33b are symmetrical with the second connection parts 362 on the first linkage unit 33a about the YZ plane.

[0191] See also Figure 23 , Figure 23 for Figure 18An enlarged view of the H region in the exploded view is shown. The second connecting portion 362 includes a second latch 3621. The second latch 3621 is configured to engage with the first accommodating space 3614. Specifically, a portion of the first accommodating space 3614 is configured to accommodate the second latch 3621. That is, the first accommodating space 3614 is not fully occupied by the second latch 3621. Thus, the second latch 3621 can movably engage within the first accommodating space 3614, allowing the second latch 3621 to rotate within the first accommodating space 3614 about a rotation axis parallel to the second direction and move in the first direction relative to the first connecting portion 361. Thus, through the engagement of the second connecting portion 362 with the first connecting portion 361, the first and second linkage units 33a, 33b are movably connected to the support bracket 32, enabling the first and second linkage units 33a, 33b to rotate relative to the pressing member and move relative to the pressing member in the first direction when the pressing member moves.

[0192] In some embodiments, please refer to Figure 23 The second connecting portion 362 further includes a through-hole 3623 provided on the fixing plate 333. The through-hole 3623 extends through both sides of the fixing plate 333 in the thickness direction. The second latch 3621 is connected to the inner wall surface of the through-hole 3623. The inner wall surface of the through-hole 3623 refers to the wall surface of the through-hole 3623 facing the central axis thereof.

[0193] Exemplarily, the through-opening 3623 is generally rectangular, and the second latch 3621 is in the shape of a rectangular plate. The second latch 3621 has a first sidewall 3621a, which is spaced apart from the inner wall of the through-opening 3623. Thus, a first latch hole 3623a is defined between the first sidewall 3621a and the inner wall of the through-opening 3623. The first latch hole 3623a is configured to engage with the first connecting segment 3611 of the first connecting portion 361.

[0194] Please continue reading Figure 23 The first locking hole 3623a is in an elongated shape, and the length direction of the first locking hole 3623a is consistent with the length direction of the first connecting section 3611. Exemplarily, the length direction of the first locking hole 3623a is parallel to the Y axis.

[0195] It is understood that the sidewall surfaces of the second latch 3621 other than the first sidewall surface 3621a may be fixedly connected to the entire inner wall surface of the through-opening 3623, or a portion of the sidewall surfaces of the second latch 3621 other than the first sidewall surface 3621a may be fixedly connected to the inner wall surface of the through-opening 3623, while another portion of the sidewall surfaces of the second latch 3621 other than the first sidewall surface 3621a may be spaced apart from the through-opening 3623. The second latch 3621 includes a top surface and a bottom surface that are oppositely disposed in the Z-axis direction, with the sidewall surface of the second latch 3621 located between the top and bottom surfaces of the second latch 3621.

[0196] In some embodiments, see Figure 23 The second latch 3621 further includes a second sidewall 3621b, which is disposed adjacent to the first sidewall 3621a. Specifically, the second sidewall 3621b is not coplanar with the first sidewall 3621a. The second sidewall 3621b may be located at one end of the lengthwise direction of the first sidewall 3621a. Optionally, the second sidewall 3621b is perpendicular to the first sidewall 3621a. The second sidewall 3621b is spaced apart from the inner wall of the through-opening 3623. A second latch hole 3623b is defined between the second sidewall 3621b of the second latch 3621 and the inner wall of the through-opening 3623. The second latch hole 3623b is elongated, and the lengthwise direction of the second latch hole 3623b may be parallel to the X-axis. The second latch hole 3623b is connected to the first latch hole 3623a. The second latch hole 3623b and the first latch hole 3623a form an L-shaped hole. As a result, at least two sidewalls of the second latch tongue 3621 are spaced apart from the inner wall of the through-opening 3623, which can improve the elasticity of the second latch tongue 3621 and facilitate the second latch tongue 3621 to extend into the first accommodating space 3614 and cooperate with the first accommodating space 3614.

[0197] In some embodiments, the second locking hole 3623 b can also be used to cooperate with the third connecting section 3613 of the first connecting portion 361 .

[0198] In some embodiments, the second latch 3621 and the fixing plate 333 are integrally formed. That is, the second latch 3621 and the fixing plate 333 are integrally formed. During processing, the first latch hole 3623a and the second latch hole 3623b can be directly formed in the fixing plate 333 to form the second latch 3621 on the fixing plate 333. This simplifies the process and facilitates fabrication.

[0199] In other embodiments, the second latch 3621 and the fixing plate 333 may also be separate structures. For example, during the manufacturing process, the through-hole 3623 may be first formed in the fixing plate 333, and then the second latch 3621 may be fixedly connected to the inner wall surface of the through-hole 3623 by bonding, welding, or clamping.

[0200] See also Figure 24-25 , Figure 24 for Figure 21 The support bracket 32 ​​is shown with Figure 17 The assembly diagram of the linkage component 33 is shown. Figure 25 for Figure 24 An enlarged view of the section I area in the assembly diagram shown. Figure 25 When the first connecting portion 361 and the second connecting portion 362 are assembled, the first connecting section 3611 is inserted into the first locking hole 3623a, and the third connecting section 3613 is inserted into the second locking hole 3623b. The second latch 3621 is located in the first accommodating space 3614.

[0201] In this way, the connection reliability between the second connecting portion 362 and the first connecting portion 361 can be improved, and the second latch 3621 can be prevented from slipping out of the first accommodating space 3614. Furthermore, the first latch hole 3623a cooperates with the first connecting segment 3611 to limit the displacement of the first linkage unit 33a in the X-axis direction. The second latch 3621 cooperates with the first accommodating space 3614 to limit the displacement of the first linkage unit 33a in the Z-axis direction. The third connecting segment 3613 cooperates with the second latch hole 3623b to limit the displacement of the first linkage unit 33a in the Y-axis direction, thereby improving the smooth movement of the touch panel 31 and the support bracket 32.

[0202] For details, please refer to Figure 26 , Figure 26 for Figure 24 The second latch 3621 is located between the bottom surface 327 of the support bracket 32 ​​and the second connecting section 3612 .

[0203] See also Figure 27 , Figure 27 for Figure 26 An enlarged view of the middle J region. The dimension d1 of the first engaging hole 3623a in the first direction (i.e., the X-axis direction) is greater than the dimension d2 of the first connecting section 3611 in the first direction. This facilitates movement of the first linkage unit 33a relative to the touchpad 31 and support bracket 32 ​​in the first direction when the touchpad 31 and support bracket 32 ​​move between the initial position and the trigger position, and also facilitates assembly of the first connecting portion 361 and the second connecting portion 362, reducing assembly difficulty.

[0204] Please continue reading Figure 27 The first engaging hole 3623a has a first inner wall surface 3623a1. The first inner wall surface 3623a1 is disposed opposite the first side wall surface 3621a of the second engaging tongue 3621. When the first linkage unit 33a moves a certain distance along the first direction toward the second linkage unit 33b, the first inner wall surface 3623a1 can abut against the first connecting segment 3611 to restrict the first linkage unit 33a from further moving away from the second linkage unit 33b. When the first linkage unit 33a moves a certain distance along the first direction toward the second linkage unit 33b, the first side wall surface 3621a of the second engaging tongue 3621 can abut against the first connecting segment 3611 to restrict the first linkage unit 33a from further moving away from the second linkage unit 33b. When the first linkage unit 33a moves a certain distance in the first direction toward the second linkage unit 33b, the first inner wall surface 3623a1 of the first engaging hole 3623a can abut against the first connecting segment 3611 to restrict further movement of the first linkage unit 33a toward the second linkage unit 33b. In this way, the first engaging hole 3623a and the first connecting segment 3611 can cooperate to restrict the displacement of the first linkage unit 33a in the first direction (i.e., the X-axis direction).

[0205] Please continue reading Figure 27 The dimension d3 of the second latch 3621 in the direction of movement of the touchpad 31 (i.e., the Z-axis direction) is smaller than the dimension d4 of the first accommodating space 3614 in the direction of movement of the touchpad 31. Thus, when the touchpad 31 and the support bracket 32 ​​move between the initial position and the trigger position, the second latch 3621 can rotate within the first accommodating space 3614, thereby enabling the first linkage unit 33a to rotate relative to the touchpad 31 and the support bracket 32.

[0206] See also Figure 27 The surface of the second connecting section 3612 facing the support bracket 32 ​​is the first top surface 3262a. When the first linkage unit 33a rotates clockwise by a certain angle, the bottom surface 327 of the support bracket 32 ​​can engage with the second latch 3621 to prevent the first linkage unit 33a from further clockwise rotation. When the first linkage unit 33a rotates counterclockwise by a certain angle, the first top surface 3262a can engage with the second latch 3621 to prevent the first linkage unit 33a from further counterclockwise rotation. In this way, the first accommodating space 3614 and the second latch 3621 can cooperate to limit the rotation angle of the first linkage unit 33a, thereby limiting the displacement of the touchpad 31 and the support bracket 32 ​​in the Z-axis direction.

[0207] Please return to Figure 25The third connecting segment 3613 is inserted into the second engaging hole 3623b. The dimension d5 of the third connecting segment 3613 in the Y-axis direction is substantially equal to the dimension d6 of the second engaging hole 3623b in the Y-axis direction. Thus, the third connecting segment 3613 cooperates with the second engaging hole 3623b to limit the first linkage unit 33a in the Y-axis direction, thereby preventing the first linkage unit 33a from shaking during the movement of the touchpad 31 and the support bracket 32 ​​between the initial position and the trigger position, thereby improving the smoothness of the movement of the touchpad 31.

[0208] It is understandable that, in other embodiments, the first connection portion 361 may not include the third connection segment 3613. In this case, the first connection portion 361 may be L-shaped.

[0209] See also Figure 28 , Figure 28 for Figure 10 A perspective view of the bracket 34 in the touchpad assembly 3 is shown. The bracket 34 includes a bracket body 341, which includes a first surface 3411 and a second surface 3412 that face each other. The bracket body 341 can be formed into an annular frame structure. Exemplarily, the bracket body 341 is a rectangular frame. In other embodiments, the bracket body 341 can also be formed into a flat plate structure.

[0210] See also Figure 29 , Figure 29 for Figure 28 The bracket 34 is shown with Figure 17 The figure shows an assembly diagram of the linkage component 33. In this embodiment, the bracket 34 is located on the side of the linkage component 33 away from the touchpad 31. The stop structure 37 includes a stop portion 371 and a limiting portion 372. The limiting portion 372 is provided on the bracket 34, and the first linkage unit 33a and the second linkage unit 33b are each provided with a stop portion 371.

[0211] See also Figure 29 The stopper 371 can be fixedly connected to the fixed plate 333. For example, the stopper 371 of the first linkage unit 33a is fixedly connected to the side of the fixed plate 333 of the first linkage unit 33a that is away from the rotating structure 35. In the direction from the second linkage unit 33b to the first linkage unit 33a, the stopper 371 of the first linkage unit 33a extends obliquely toward the bracket 34, while the stopper 371 of the second linkage unit 33b extends obliquely away from the bracket 34. The linkage structure 33 has an M-shaped structure. This facilitates the abutment and engagement of the stopper 371 with the bracket 34.

[0212] Optionally, the stopper 371 is plate-shaped, so as to improve the rigidity of the stopper 371 and prevent the stopper 371 from being deformed when the touch panel 31 is pressed.

[0213] In some embodiments, the stopper 371 and the fixing plate 333 are integrally formed. That is, the stopper 371 and the fixing plate 333 are integrally formed. This simplifies the structure of the linkage structure 33 and improves the connection strength between the stopper 371 and the fixing plate 333.

[0214] See also Figure 29 The bracket 34 is provided with a plurality of limiting portions 372. Some of the limiting portions 372 are configured to connect with the stopper 371 on the first linkage unit 33a, while others are configured to connect with the stopper 371 on the second linkage unit 33b. For ease of description, the limiting portion 372 configured to connect with the stopper 371 on the first linkage unit 33a is referred to as a first limiting portion 372a, and the limiting portion 372 configured to connect with the stopper 371 on the second linkage unit 33b is referred to as a second limiting portion 372b.

[0215] There are two first limiting portions 372a, spaced apart in the Y-axis direction. In some embodiments, the two first limiting portions 372a are symmetrically arranged about the XZ plane. There are two second limiting portions 372b, spaced apart in the Y-axis direction. The first limiting portions 372a and the second limiting portions 372b are symmetrically arranged about the YZ plane.

[0216] See also Figure 30 , Figure 30 for Figure 29 The position limiting portion 372 includes a first baffle 3721 and a second baffle 3722 .

[0217] The first baffle 3721 is fixedly connected to the first surface 3411 of the bracket body 341. The first baffle 3721 can be in the shape of a flat plate. The first baffle 3721 can be arranged perpendicular to the first surface 3411. The length direction of the first baffle 3721 can be parallel to the Y axis.

[0218] The second baffle 3722 is fixedly connected to an end of the first baffle 3721 away from the bracket body 341. A first limiting space 3724 is defined between the first surface 3411 of the bracket body 341, the second baffle 3722, and the first baffle 3721. The stopper 371 is movably engaged with the first limiting space 3724.

[0219] Specifically, at least a portion of the stopper 371 is located within the first limiting space 3724. When the touchpad and the support bracket 32 ​​move between the initial position and the trigger position, the stopper 371 can rotate within the first limiting space 3724 and move relative to the bracket 34 in the first direction.

[0220] See also Figure 31 , Figure 31 for Figure 11 An enlarged view of the middle K area. The limiting portion 372 includes a first limiting surface 3724a and a second limiting surface 3724b that are relatively arranged in the moving direction of the pressing component (that is, in the Z-axis direction). In this embodiment, the bracket 34 is located on the side of the linkage structure 33 away from the pressing component. The first limiting surface 3724a is formed on the bracket body 341, and the second limiting surface 3724b is formed on the second baffle 3722. The second limiting surface 3724b is the inner wall surface of the first limiting space 3724 facing the bracket body 341. That is, the first limiting surface 3724a faces the pressing component.

[0221] Figure 31 The solid line in FIG shows a schematic diagram of the cooperation between the stop portion 371 and the limiting portion 372 when the pressing component is in the initial position. Figure 31 The dashed line in FIG shows a schematic diagram of the cooperation between the stopper 371 and the limiting portion 372 when the pressing member is in the trigger position. When the pressing member is in the initial position, the end of the stopper 371 away from the fixing plate 333 (i.e., the free end of the stopper 371) abuts against the first limiting surface 3724a, and in the first direction, the free end of the stopper 371 is spaced apart from the inner wall surface of the first limiting space 3724. Thus, when the user presses the pressing member to move it from the initial position to the trigger position, the stopper 371 always abuts against the first limiting surface 3724a under the action of the pressing force, and the first linkage unit 33a and the second linkage unit 33b respectively rotate in a direction away from the pressing member with the position where the stopper 371 connects to the first limiting surface 3724a as the rotation fulcrum, and the first linkage unit 33a and the second linkage unit 33b respectively move along the first direction away from the rotating structure 35.

[0222] See also Figure 32 , Figure 32 for Figure 31 Another schematic diagram of the cooperation between the limiting portion 372 and the stopping portion 371 is shown. Figure 32 The solid line in FIG shows a schematic diagram of the cooperation between the stopper 371 and the limiting portion 372 when the pressing component is in the trigger position. Figure 32 The dotted line in FIG shows a schematic diagram of the cooperation between the stop portion 371 and the limiting portion 372 when the pressing component is in the initial position.

[0223] When the user releases the pressing force on the pressing component, the pressing component moves from the trigger position to the initial position. The stopper 371 of the first linkage unit 33a moves upward with the first linkage unit 33a, and the stopper 371 of the second linkage unit 33b moves upward with the second linkage unit 33b. When the stopper 371 abuts the second limiting surface 3724b, the first and second linkage units 33a and 33b rotate toward the pressing component, with the position where the stopper 371 abuts the second limiting surface 3724b serving as the rotation fulcrum. The first and second linkage units 33a and 33b respectively move along the first direction toward the rotation structure 35.

[0224] In some embodiments, see Figure 30 Combined with Figure 31-Figure 32 In the direction approaching the rotating structure 35, the second limiting surface 3724b extends obliquely in a direction away from the bracket body 341. Thus, when the pressing component moves from the trigger position to the initial position, the second limiting surface 3724b facilitates abutment and engagement with the stopper 371. Furthermore, during assembly, the stopper 371 is easily assembled into the first limiting space 3724, thereby reducing assembly difficulty and improving assembly efficiency.

[0225] Please continue reading Figure 30 The limiting portion 372 further includes a third baffle 3723, which is connected between the first baffle 3721 and the second baffle 3722. Specifically, the third baffle 3723 is fixedly connected to the first surface 3411 and is located on one side of the length direction of the first baffle 3721. Specifically, the third baffle 3723 can be located on one side of the first baffle 3721 along the second direction (i.e., the Y-axis direction). In this way, the third baffle 3723 can limit the first linkage unit 33a in the Y-axis direction, thereby reducing the shaking of the first linkage unit 33a during the movement of the touch pad 31 between the initial position and the trigger position, thereby improving the movement stability of the touch pad 31.

[0226] In other embodiments, the limiting portion 372 may not include the third baffle 3723 .

[0227] See also Figure 29 In some embodiments, the two first limiting portions 372a are spaced apart in the second direction. This can reduce the total space occupied by the two first limiting portions 372a and prevent the first limiting portions 372a from interfering with other structures of the touchpad assembly 3.

[0228] It is understood that in other embodiments, the two first limiting portions 372a may also be butt-connected. In this case, the two first baffles 3721 are connected, and the two second baffles 3722 are connected. In this way, the two first limiting portions 372a can be connected to form a single integral structure. The structure and number of the second limiting portions 372b are identical to those of the first limiting portions 371a, and will not be further described here.

[0229] For further information, please refer back to Figure 28 The bracket 34 further includes a first rib 342 and a second rib 343. The first rib 342 and the second rib 343 are both fixedly connected within the bracket body 341. Exemplarily, the first rib 342 and the second rib 343 intersect. Optionally, the first rib 342 extends parallel to one diagonal of the bracket body 341, and the second rib 343 extends parallel to the other diagonal of the bracket body 341.

[0230] A trigger bump 340 is provided at the intersection of the first rib 342 and the second rib 343, protruding toward the touchpad 31. When a user presses the touchpad 31, the trigger bump 340 presses the trigger switch 3121, triggering it. In some embodiments, the trigger bump 340 can be stamped, which simplifies the process and facilitates fabrication.

[0231] Therefore, by arranging the intersecting first rib 342 and second rib 343 in the bracket body 341, on the one hand, it is convenient to arrange the trigger protrusion 340 for cooperating with the trigger switch 3121 on the bracket 34, and on the other hand, the first rib 342 and the second rib 343 can play a role in enhancing the structural strength of the bracket body 341, which is beneficial to improving the overall structural strength of the bracket 34.

[0232] In other embodiments, only the first rib 342 may be provided in the bracket body 341 without the second rib 343. The first rib 342 may be formed in a straight line, a broken line, or a curved line. The triggering protrusion 340 is provided on the first rib 342.

[0233] See also Figure 29 , two limit plates 345 are provided on the bracket body 341. The limit plates 345 are arranged perpendicular to the bracket body 341. Figure 39 The two limiting plates 345 correspond one-to-one with the two rotating structures 35, and the limiting plates 345 are located outside the corresponding rotating structures 35. In this way, the limiting plates 345 can limit the movement of the rotating structures 35 in the Y direction, preventing the linkage component 33 from shaking when the touchpad 31 and support bracket 32 ​​move between the initial position and the trigger position, thereby improving the movement smoothness of the touchpad 31 and support bracket 32.

[0234] Please continue reading Figure 29 The bracket body 341 is provided with a plurality of connecting ears 344. The connecting ears 344 are spaced apart in the circumferential direction of the bracket body 341. The connecting ears 344 are used to be fixedly connected to the C-shell 11. In some embodiments, the connecting ears 344 are L-shaped.

[0235] See also Figure 33 , Figure 33 for Figure 28 The bracket 34 is shown as a partial schematic diagram of the assembly of the C-shell 11. The connecting ear 344 is fixedly connected to the C-shell 11 by a fastener 38. The fastener 38 is a screw, bolt, etc.

[0236] In this embodiment, bracket 34 is located on a side of linkage component 33 that is away from support bracket 32. That is, bracket 34 and support bracket 32 ​​are located on either side of linkage component 33. In other embodiments, support bracket 32 ​​and bracket 34 may be located on the same side of linkage component 33. In this case, at least a portion of bracket 34 may be formed from a C-shell.

[0237] On the basis of any of the above embodiments, in order to reduce the overall thickness of the touch panel assembly 3, refer to Figure 34 , Figure 34 for Figure 9 The diagram shows an orthographic projection of the touchpad assembly 3 on a reference plane S. Reference plane S is a plane perpendicular to the direction of movement of the touchpad 31 and support bracket 32. The orthographic projections of the touchpad 31 and support bracket 32 ​​on reference plane S are first projection S1. Specifically, the orthographic projection of the pressing component on reference plane S is first projection S1, and the orthographic projection of the stop structure 37 on reference plane S is second projection S2. The second projection S2 does not overlap with the first projection S1. In other words, there is no overlapping area between the second projection S2 and the first projection S1.

[0238] This prevents overlap between the stop structure 37, the touchpad 31, and the support bracket 32 ​​in the thickness direction of the keyboard host 200, thereby reducing the overall thickness of the touchpad assembly 3 and the space occupied by the touchpad assembly 3 in the thickness direction of the keyboard host 200, thereby further facilitating a thinner and lighter keyboard host 200. Furthermore, in embodiments where the battery 5 is located below the touchpad assembly 3, the thickness of the battery 5 can be increased without increasing the overall thickness of the keyboard host 200, thereby increasing the volume of the battery 5 and improving the battery life of the electronic device 1000.

[0239] Based on any of the above examples, please continue to refer to Figure 34, the orthographic projection of the rotating structure 35 on the reference plane is the third projection S3, and the third projection S3 does not overlap with the first projection S1. That is, there is no overlapping area between the third projection S3 and the first projection S1. In this way, the overlapping of the dimensions of the rotating structure 35, the touchpad 31, and the supporting bracket 32 ​​in the thickness direction of the keyboard host 200 can be avoided, which is beneficial to reducing the overall thickness of the touchpad assembly 3, thereby reducing the space occupied by the touchpad assembly 3 in the thickness direction of the keyboard host 200, and further contributing to the thinness of the keyboard host 200. In addition, in the embodiment where the battery 5 is located below the touchpad assembly 3, the thickness of the battery 5 can be increased without increasing the overall thickness of the keyboard host 200, thereby increasing the volume of the battery 5 and improving the battery life of the electronic device 1000.

[0240] In this embodiment, neither the second projection S2 nor the third projection S3 overlaps with the first projection S1. It is understood that in other embodiments, only the second projection S2 and the first projection S1 may overlap, while the third projection S3 overlaps. Alternatively, in still other embodiments, the third projection S3 and the first projection S1 may overlap, while the second projection S2 and the first projection S1 overlap. This can also reduce the thickness of the touchpad assembly 3 to a certain extent.

[0241] In other embodiments, see Figure 35 , Figure 35 The touch panel assembly 3 of another embodiment of the present application is a cross-sectional view. The touch panel assembly 3 in this embodiment includes a touch panel, a support bracket 32, a linkage component 33 and a bracket 34. The touch panel assembly 3 in this embodiment is Figure 11 The difference between the touch panel assembly 3 in the embodiment shown is that the structure of the stop structure 37 in this embodiment is different from that in the embodiment shown in FIG. Figure 11 The structure of the stop structure 37 in the embodiment shown is different. The stop structure 37 in this embodiment includes a stop portion 371 and a limiting portion 372. The stop portion 371 is provided on the bracket 34, and the first linkage unit 33a and the second linkage unit 33b are respectively provided with the limiting portion 372.

[0242] For details, please refer to Figure 36 , Figure 36 for Figure 35 The two stoppers 371 of this embodiment are respectively provided at both ends of the length direction of the bracket body 341 , and extend obliquely from the bracket 34 to the linkage structure 33 in the direction away from the rotation structure 35 .

[0243] The limiting portion 372 includes a first limiting space 3724. The stopper 371 is movably engaged within the first limiting space 3724. Specifically, the limiting portion 372 includes a first baffle 3721 and a second baffle 3722. The first baffle 3721 is connected to the fixed plate 333 of the first linkage unit 33a, and the second baffle 3722 is connected to the end of the first baffle 3721 away from the fixed plate 333. The first limiting space 3724 is defined between the first baffle 3721, the second baffle 3722, and the fixed plate 333. The inner wall surface of the first limiting space 3724 facing the bracket body 341 forms a second limiting surface 3724b, which is disposed opposite the first limiting surface 3724a. The first limiting surface 3724a is formed on the side surface of the second baffle 3722 facing the bracket body 341. When the pressing component moves from the initial position to the trigger position, the first limiting surface 3724 a abuts against the stopper 371 . When the pressing component moves from the trigger position to the initial position, the second limiting surface 3724 b abuts against the stopper 371 .

[0244] See also Figure 37 , Figure 37 Schematic diagram of the partial structure of the support bracket 32, the linkage component 33 and the bracket 34 provided in some other embodiments of the present application. In this embodiment, the limiting portion 372 and the stopping portion 371 are both hook-shaped.

[0245] For details, please refer to Figure 38 , Figure 38 for Figure 37 A schematic diagram of a partial assembly of the first linkage unit 33a and the bracket 34. The limiting portion 372 includes a first baffle 3721 and a second baffle 3722. The first baffle 3721 is fixedly connected to the first surface 3411. The first baffle 3721 and the second baffle 3722 can be formed as flat plates or curved plates. A first limiting space 3724 is defined between the first baffle 3721 and the second baffle 3722. The inner wall surface of the first limiting space 3724 facing the bracket body 34 forms a second limiting surface 3724b.

[0246] The stopper 371 is disposed on a side surface of the fixing plate 333 facing the bracket 34. The stopper 371 includes a first fixing section 3711 and a first abutting section 3712. One end of the first fixing section 3711 is fixedly connected to the side surface of the fixing plate 333 facing the bracket 34, and the other end of the first fixing section 3711 extends toward the bracket 34. The first fixing section 3711 is flat or curved. The first abutting section 3712 is fixedly connected to the end of the first fixing section 3711 facing away from the fixing plate 333. A second limiting space 3713 is defined between the fixing plate 333, the first fixing section 3711, and the first abutting section 3712. The inner wall surface of the second limiting space 3713 facing the bracket 34 forms a third limiting surface 3713a, and the inner wall surface of the second limiting space 3713 facing the fixing plate 333 forms a fourth limiting surface 3713b.

[0247] The first stop section 3712 can extend into the first limiting space 3724 and cooperate with the first limiting space 3724. The second baffle 3722 can extend into the second limiting space 3713 and cooperate with the second limiting space 3713. When the pressing component moves from the initial position to the trigger position, the first limiting surface 3724a abuts against the first stop section 3712. When the pressing component moves from the trigger position to the initial position, the second limiting surface 3724b abuts against the first stop section 3712. When the pressing component moves from the initial position to the trigger position, the first limiting surface 3724a abuts against the stop portion 371, and / or the first limiting portion 372 abuts against the third limiting surface 3713a. When the pressing component moves from the trigger position to the initial position, the second limiting surface 3724b abuts against the stop portion 371, and / or the fourth limiting surface 3713b abuts against the first limiting portion 372.

[0248] In this way, the first linkage unit 33 a can be limited in the Z-axis direction by the cooperation between the stop portion 371 and the first limiting portion 372 .

[0249] See also Figure 39 , Figure 39 for Figure 37 Schematic diagram of the assembly of the first linkage unit 33a and the support bracket 32. In this embodiment, the connection structure 36 includes a first connection portion 361 and a second connection portion 362. The first connection portion 361 is provided on the support bracket 32, and the second connection portion 362 is provided on the first linkage unit 33a.

[0250] Specifically, the first connecting portion 361 is disposed on a side surface of the support bracket 32 ​​facing the first linkage unit 33a. The first connecting portion 361 includes a first latch 3615, which defines a first accommodating space 3614. The first latch 3615 is in the shape of a hook. For example, the first latch 3615 can be in the shape of an arcuate latch, an L-shaped hook, or the like. In this embodiment, the first accommodating space 3614 is defined between the first latch 3615 and the bottom surface 327 of the support bracket 32. In other embodiments, the first accommodating space 3614 can also be defined by the first latch 3615 itself.

[0251] Please continue reading Figure 39 The second connecting portion 362 includes a second latch 3621. The second latch 3621 is fixedly connected to the surface of the fixing plate 333 on one side facing the support bracket 32. The second latch 3261 is in the shape of a hook. For example, the second latch 3261 can be in the shape of an arc hook, an L-shaped hook, etc. The second latch 3261 includes a second accommodating space 3624. Figure 39 The second accommodating space 3264 is defined between the second latch 3261 and the fixing plate 333. In other embodiments, the second accommodating space 3624 can also be defined by the second latch 3261 itself. Part of the second accommodating space 3624 is used to accommodate the first latch 3615, and part of the first accommodating space 3614 is used to accommodate the second latch 3261, so that the second connecting portion 362 can move relative to the first connecting portion 361 in the first direction and rotate about a rotation axis parallel to the second direction.

[0252] In this way, while achieving the connection between the first linkage unit 33 a and the supporting bracket 32 ​​, it is possible to avoid opening a hole in the fixing plate 333 , thereby improving the structural strength of the fixing plate 333 .

[0253] In this embodiment, the second linkage unit 33 b is connected to the support bracket 32 ​​in the same manner as the first linkage unit 33 a is connected to the support bracket 32 ​​, and details thereof will not be repeated herein.

[0254] It is understood that in other embodiments, the connection structure 36 in the touch panel assembly 3 may be connected to Figure 10 The structure of the connecting structure 36 in the embodiment shown is the same, and the stop structure 37 can be the same as Figure 37 Alternatively, in some other embodiments, the connection structure 36 in the touch panel assembly 3 may be the same as the structure of the stop structure 37 in the embodiment shown. Figure 37 The structure of the connecting structure 36 in the embodiment shown is the same, and the stop structure 37 can be the same as Figure 10 The structures of the stop structures 37 in the illustrated embodiments are identical.

[0255] In other embodiments, the connection structure 36 may further include a first hinge, a second hinge, and a first slide. The support bracket 32 ​​is provided with a first hinge, and the first linkage unit 33a and the second linkage unit 33b are each provided with a second hinge. The second hinge is hingedly connected to the first hinge, and the first slide is provided on the support bracket 32. The first hinge and the first slide slide slide along the first direction. In this manner, the connection structure 36 can also enable the first linkage unit 33a and the second linkage unit 33b to rotate about a rotation axis parallel to the second direction and to move relative to the support bracket 32 ​​along the first direction.

[0256] Similarly, in other embodiments, the stop structure 37 may include a third hinge, a fourth hinge, and a second slide. The bracket 34 is provided with a third hinge, and the first linkage unit 33a and the second linkage unit 33b are each provided with a fourth hinge, the fourth hinge being hingedly connected to the third hinge. The second slide is provided on the bracket 34, and the third hinge slidably engages with the second slide along the first direction. In this manner, the stop structure 37 can similarly limit the movement of the first linkage unit 33a and the second linkage unit 33b in the Z-axis direction, while enabling the first linkage unit 33a and the second linkage unit 33b to rotate about a rotation axis parallel to the second direction and move in the first direction relative to the bracket 34.

[0257] See also Figure 40 , Figure 40 This is a cross-sectional view of the touch panel assembly 3 in some other embodiments of the present application. Figure 11 The difference of the touchpad assembly 3 shown is that the bracket 34 in this embodiment is located on the side of the first linkage unit 33a facing the support bracket 32. That is, the bracket 34, the touchpad 31, and the support bracket 32 ​​are all located on the same side of the linkage component 33.

[0258] See also Figure 40 The bracket 34 includes a bracket body 341 and a stopper 372. In this embodiment, the bracket body 341 can be independent of the C-shell 11. In this case, the bracket body 341 can be fixedly connected to the C-shell 11. Alternatively, in other embodiments, the bracket body 341 can be defined by the C-shell 11. In other words, a portion of the C-shell 11 constitutes the bracket body 341 in this embodiment. This further reduces the overall thickness of the touchpad assembly 3.

[0259] The stopper 371 is fixedly connected to the side of the fixed plate 333 away from the rotating structure 35. One end of the stopper 371 is fixedly connected to the fixed plate 333. The other end of the stopper 371 extends obliquely in the direction from the linkage component 33 to the support bracket 32, away from the rotating structure 35.

[0260] See also Figure 41 , Figure 41 for Figure 40 An enlarged view of the R-section region in the cross-sectional view is shown. A first limiting portion 372 is provided on the bracket body 341. The stopper 371 is movable along a first direction and rotatably connected to the limiting portion 372. Specifically, the limiting portion 372 defines a first limiting space 3724, within which the stopper 371 is located.

[0261] Specifically, the limiting portion 372 includes a first baffle 3721 and a second baffle 3722, with a first limiting space 3724 defined therebetween. In this embodiment, a first limiting surface 3724a is formed on the inner wall surface of the first limiting space 3724 facing the bracket body 341. That is, the first limiting surface 3724a faces the pressing component. The second limiting surface 3724b is opposite the first limiting surface 3724a. When the pressing component moves from the initial position to the trigger position, the first limiting surface 3724a abuts against the stop portion 371. When the pressing component moves from the trigger position to the initial position, the second limiting surface 3724b abuts against the stop portion 371.

[0262] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0263] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
