Specifically, the user can control the movement of the cursor on the display 100 by using the touch action of the finger on the surface of the touch panel 31 (including actions such as swiping and clicking) to perform "cursor navigation", "selection" and "confirmation" of the mouse. Wait for operations.

Please refer to FIGS. 6-7 . FIG. 6 is a perspective view of the touch panel 31 provided by some embodiments of the present application. FIG. 7 is a cross-sectional view of the touch panel 31 shown in FIG. 6 at line C-C. The touch panel 31 includes a touch substrate 311 and a circuit board 312 . The touch substrate 311 is used to receive user touch and press operations. The touch substrate 311 is fixedly connected to one side surface of the circuit board 312 . For example, the touch substrate 311 is fixedly connected to the circuit board 312 through adhesive glue.

Specifically, please refer to Figures 6-7. The touch substrate 311 is plate-shaped. For example, the touch substrate 311 is in the shape of a rectangular plate. The length direction of the touch substrate 311 is parallel to the X-axis direction, the width direction of the touch substrate 311 is parallel to the Y-axis direction, and the thickness direction of the touch substrate 311 is parallel to the Z-axis direction. The touch substrate 311 has a touch surface 311a, and the touch surface 311a is located on a side surface of the touch substrate 311 away from the circuit board 312. The touch surface 311a constitutes a partial area of the outer surface of the keyboard host 200, and the touch surface 311a supports operations such as clicking and sliding with the user's fingers.

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

The circuit board 312 is equipped with electronic components and circuits for transmitting and processing touch signals, pressure signals and vibration signals. The shape of the circuit board 312 is adapted to the shape of the touch substrate 311 . For example, the circuit board 312 is in the shape of a rectangular plate.

Referring to FIG. 7 , a trigger switch 3121 is provided on a side surface of the circuit board 312 away from the touch substrate 311 . The trigger switch 3121 may be disposed in the middle of the circuit board 312. Specifically, the trigger switch 3121 protrudes from the surface of the circuit board 312 away from the touch substrate 311 . The trigger switch 3121 can be triggered when squeezed.

Optionally, the trigger switch 3121 is a flexible switch. That is, the trigger switch 3121 can elastically deform. For example, the trigger switch 3121 is a metal spring piece. The trigger switch 3121 can generate elastic deformation after being squeezed, and can automatically return to its original state after the pressure is released.

Specifically, the touch panel 31 includes an initial position and a trigger position, and the touch panel 31 can move between the initial position and the trigger position, so that the trigger switch 3121 switches between an untriggered initial state and a triggered trigger state. Specifically, when the touch panel 31 is in the initial position, the trigger switch 3121 is in the initial state; when the touch panel 31 is in the trigger position, the trigger switch 3121 is in the trigger state. When the trigger switch 3121 is triggered, the user can control the electronic device 1000 through the touch panel 31 .

The moving direction of the touch panel 31 is parallel to the Z-axis. The "initial position of the touch panel 31" refers to the position of the touch panel 31 when the touch panel 31 has not been pressed. The "trigger position of the touch panel 31" refers to the position of the touch panel 31 when the touch panel 31 is pressed and moved downward until the trigger switch 3121 is in the triggered state.

In order to facilitate the user to trigger the trigger switch 3121, the keyboard host 200 may be provided with a trigger bump 340 corresponding to the trigger switch 3121. Please refer to Figure 8, which is an enlarged view of the area A in Figure 5. When the user presses the touch panel 31 and applies downward pressing force F to the touch panel 31, the touch panel 31 can move from the initial position toward the trigger position. When the touch panel 31 moves downward to the trigger position, the trigger switch 3121 can be triggered. The bump 340 is squeezed to be triggered, and at this time, the trigger switch 3121 undergoes elastic deformation. When the user removes the pressing force F on the touch panel 31 , the trigger switch 3121 resumes its deformation, so that the touch panel 31 can move upward to the initial position under the elastic force of the trigger switch 3121 .

It can be understood that in other embodiments, the triggering bump 340 can also be configured as an elastic member. In this case, the trigger switch 3121 may be an elastic switch or an inelastic switch.

The structure of the touch panel assembly 3 in the above embodiment is simple, but because the trigger switch 3121 is located in the middle area of the touch panel 31, when the user presses the edge of the touch panel 31, the touch panel 31 may not be pressed, or the touch panel 31 may not move. Only the touch panel 31 can be pressed with a pressing force of more than 100%, and the trigger switch 3121 cannot be triggered, making the trigger switch 3121 less sensitive and affecting the user's input experience.

In order to solve the above technical problem, pressing any position of the touch panel 31 can cause the trigger switch 3121 to be triggered. Please refer to FIGS. 9-10. FIG. 9 is a perspective view of the touch panel assembly 3 provided by other embodiments of the present application. FIG. 10 is an exploded view of the touch panel assembly 3 shown in FIG. 9 .

It should be noted that FIGS. 9-10 only schematically illustrate some components included in the touch panel assembly 3, and the actual shapes, sizes, positions and structures of these components are not affected by FIGS. 9-10 and the following descriptions. Drawings limited. In addition, the coordinate system in FIG. 9 and the coordinate system in FIG. 2 are represented as the same coordinate system. That is to say, the orientation relationship of the various components of the touch panel assembly 3 in Figure 9 in the coordinate system shown in Figure 9 is the same as the orientation relationship between the various components of the touch panel assembly 3 in Figure 2 when it is applied to the keyboard host 200 shown in Figure 2 The orientation relationships in the coordinate systems shown are the same. In addition, the shape of each component in the touch panel assembly 3 described below as "rectangular" and "square" both represent a rough shape, and there may or may not be rounded corners between adjacent two sides. Furthermore, the orientation relationship qualifiers such as “parallel”, “perpendicular”, “same direction”, “same direction”, and “opposite direction” used to describe various components in the touch panel assembly 3 below all indicate approximate directions that allow certain errors. . For example, an error of ±10° may be allowed.

The support bracket 32 is used to support the touch panel 31 and to connect the linkage component 33 . Specifically, please refer to FIG. 9 . The touch panel 31 is fixedly connected to the support bracket 32 . When the user presses the touch panel 31 downward, the support bracket 32 moves together with the touch panel 31 . In this embodiment, the touch panel 31 and the support bracket 32 are both part of the pressing component. That is, in this embodiment, the pressing member includes the touch panel 31 and the support bracket 32 .

Please refer to FIGS. 9 and 10 , the linkage component 33 is provided on one side of the support bracket 32 . Specifically, the linkage component 33 is provided on the side of the support bracket 32 away from the touch panel 31 .

The first direction is perpendicular to the moving direction of the touch panel 31 . That is, the first direction is perpendicular to the Z-axis.

In some embodiments, the first direction is parallel to the length direction of the keyboard host 200 . That is, the first direction is parallel to the X-axis. In this way, the space in the length direction of the keyboard host 200 (that is, the X-axis direction) can be fully utilized, and the space occupied by the linkage component 33 in the width direction of the keyboard host 200 (that is, the Y-axis direction) is reduced, which is beneficial to Reducing the gap between the touch panel 31 and the edge of the carrier plate body 1111 is beneficial to reducing the width of the keyboard host 200 and achieving a miniaturized design of the keyboard host 200 .

It can be 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 moving direction of the touch panel 31 .

For the convenience of description, in the following description, it is taken as an example that 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 first linkage unit 33a is located on the left side of the second linkage unit 33b. . Among them, the direction "left" mentioned in this application refers to the direction of the user's left hand side when the user uses the electronic device 1000. Correspondingly, the direction "right" mentioned in this application refers to the direction of the user's left hand side when the user uses the electronic device 1000. Left hand direction. In addition, it should be noted that in the description of this application, the orientation or positional relationship indicated by the terms "left", "right", "inner", "outer", etc. are based on the orientation or positional relationship shown in the drawings, and only It is for the convenience of describing the present invention but does not require that the present invention must be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application.

Referring to FIG. 9 , the first linkage unit 33 a and the second linkage unit 33 b are rotatably connected through the rotating structure 35 . Specifically, please refer to FIG. 10 . The first linkage unit 33 a includes a first end 331 , and the second linkage unit 33 b includes a second end 332 . The first end 331 and the second end 332 are rotatably connected through the rotating structure 35 .

Please refer to FIG. 9 in conjunction with FIG. 11. FIG. 11 is a cross-sectional view of the touch panel assembly 3 shown in FIG. 9 at line D-D. The first linkage unit 33a and the second linkage unit 33a are respectively connected to the support bracket 32 through the connection structure 36, and when the touch panel 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 33a The units 33b respectively rotate around rotation axes parallel to the second direction, and the first linkage unit 33a and the second linkage unit 33b respectively move in the first direction relative to the support bracket 32 .

Wherein, the second direction is perpendicular to the first direction, and the second direction is perpendicular to the moving direction of the pressing component. For example, the second direction is parallel to the Y-axis.

It can be understood that in other embodiments, the pressing component may only include the touch panel 31 and not the supporting bracket 32 . In this embodiment, the first linkage unit 33a can be connected to the touch panel 31 through the connection structure 36, and the second linkage unit 33b can be connected to the touch panel 31 through the connection structure 36.

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

Please refer to Figure 9 in conjunction with Figure 11. The first linkage unit 33a and the second linkage unit 33b are respectively connected to the bracket 34 through the stopper structure 37. In the first direction, the stopper structure 37 is located away from the rotation structure of the connection structure 36. 35 on one side. The stopper structure 37 is used to limit the first linkage unit 33a and the second linkage unit 33b in the moving direction of the pressing member (that is, the Z-axis direction).

For convenience of description, the stop structure 37 used to connect the first linkage unit 33a and the bracket 34 is called the first stop structure, and the stop structure 37 used to connect the second linkage unit 33b and the bracket 34 is called the second stop structure. The stop structure, the connection structure 36 used to connect the first linkage unit 33a and the support bracket 32 is called the first connection structure, and the connection structure 36 used to connect the second linkage unit 33b and the support bracket 32 is called the second connection. structure. Referring to FIG. 11 , the first stop structure is located on the side of the first connection structure away from the rotating structure 35 , and the second stop structure is located on the 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.

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

The following describes the movement process of the pressing component and the linkage component 33 in the touch panel assembly 3 of this embodiment with reference to FIGS. 12 and 13 .

Please refer to FIG. 12 , which is a simplified schematic diagram of the touch panel 31 of the touch panel assembly 3 shown in FIG. 11 moving from the initial position to the trigger position. In FIG. 12 , the touch panel 31 and the linkage component 33 shown by the solid lines are in the initial position, and the touch panel 31 and the linkage component 33 shown by the dotted lines are in the triggering position. Among them, the support bracket 32 is not shown in FIG. 12 . For convenience of description, the position where the first linkage unit 33a is connected to the bracket 34 is called the "first connection position P1", the position where the first linkage unit 33a is connected to the pressing member is called the "second connection position P2", and the position where the first linkage unit 33a is connected to the pressing member is called the "second connection position P2". The position where the unit 33b is connected to the bracket 34 is called the "third connection position P3", and the position where the second linkage unit 33b is connected to the pressing member is called the "fourth connection position P4".

Please refer to Figure 12 in conjunction with Figure 11. Since the first linkage unit 33a and the second linkage unit 33b are respectively connected to the bracket 34 through the first stop structure 37a and the second stop structure 37b, and in the first direction, the first The stopper structure 37a is located on the side of the first connection structure 36a away from the rotation structure 35, and the second stopper structure 37b is located on the side of the second connection structure 36b away from the rotation structure 35. The first stopper structure 37a is used to limit the first linkage unit 33a in the Z-axis direction. The second stopper structure 37b is used to limit the second linkage unit 33b in the Z-axis direction. When the user presses down the left edge area of the touch panel 31, the left edge area of the touch panel 31 moves downward, and the first linkage unit 33a moves downward with the touch panel 31. In this way, the first linkage unit 33a connects with the first linkage unit 33a. Position P1 is a rotation fulcrum that rotates clockwise relative to the touch panel 31 and the bracket 34 . That is, the first end 331 of the first linkage unit 33a rotates downward relative to the first connection position P1.

Please refer to Figure 12. 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 first linkage unit 33a uses the first connection position P1 as a rotation fulcrum relative to the touch panel 31. When the bracket 34 rotates clockwise, the second connection position P2 moves in the first direction toward the second linkage unit 33b relative to the touch panel 31, and the first connection position P1 moves away from the second linkage unit 33b in the first direction relative to the bracket 34. The direction of the linkage unit 33b moves. Moreover, 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.

Please continue to refer to Figure 12 and combine with Figure 11, because the second linkage unit 33b is connected to the bracket 34 through the second stop structure 37b, and in the first direction, the second stop structure 37b is located away from the rotation of the second connection structure 36b. On one side of the 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 touch panel 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 in the first direction toward the first linkage unit 33a relative to the touch panel 31, and the third connection position P3 moves in the first direction away from the first linkage unit 33a, and can then be moved through the first linkage unit 33a. The second linkage unit 33b drives the right edge area of the touch panel 31 to move downward.

In this way, when the user presses down the left edge area of the touch panel 31, the right edge area of the touch panel 31 can also move downward, so that the touch panel 31 can move downward stably as a whole and prevent the touch panel 31 from warping. , thereby triggering the trigger switch 3121 smoothly, thereby improving the sensitivity of the trigger switch 3121.

In some embodiments, the first linkage unit 33a and the second linkage unit 33b are arranged symmetrically with respect to the YZ plane. In this case, when the touch panel 31 moves between the initial position and the triggering position, the movement of the first linkage unit 33a and the movement of the second linkage unit 33b are symmetrical with respect to the symmetry plane of the two.

Please continue to refer to Figure 12. Similarly, when the user presses down the right edge area of the touch panel 31, the right edge area of the touch panel 31 moves downward, and the second linkage unit 33b moves downward with the touch panel 31, and At the same time, the second linkage unit 33b rotates counterclockwise relative to the touch panel 31 and the bracket 34 with the third connection position P3 as a rotation fulcrum, and the fourth connection position P4 moves closer to the first linkage unit 33a relative to the touch panel 31 in the first direction. The third connection position P3 moves in the first direction away from the first linkage unit 33a relative to the bracket 34 .

Moreover, 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 in the first direction toward the second linkage unit 33b relative to the touch panel 31. The first connection position P1 By moving in the first direction away from the second linkage unit 33b, the left edge area of the touch panel 31 can be driven downward by the first linkage unit 33a.

In this way, when the user presses down the right edge area of the touch panel 31, the left edge area of the touch panel 31 can also move downward, so that the touch panel 31 can move downward stably as a whole and prevent the touch panel 31 from warping. , thereby triggering the trigger switch 3121 smoothly, thereby improving the sensitivity of the trigger switch 3121.

Therefore, in the touch panel assembly 3 in the embodiment of the present application, by providing the linkage component 33, when any position of the touch surface 331a of the touch panel 31 is pressed, the touch panel assembly 3 can pass through one of the first linkage unit 33a and the second linkage unit 33b. One drives the other of the first linkage unit 33a and the second linkage unit 33b to move downward, so that the touch panel 31 can move downward stably as a whole, preventing the touch panel 31 from being lifted, and thus the trigger switch 3121 can be smoothly triggered, through mechanical means. Realizing the full-area touch control of the touch panel 31 not only improves the sensitivity of the trigger switch 3121, but also brings a good input experience to the user. Compared with technical solutions that use piezoelectric ceramics or motors to achieve full-area touch control of the touch panel 31, It also reduces costs.

Moreover, in the touch panel assembly 3 in the embodiment of the present application, the first linkage unit 33a and the second linkage unit are respectively connected to the bracket 34 through the first stopper structure 37a and the second stopper structure 37b, and in the first direction, The first stopper structure 37a is located on the side of the first connection structure 36a away from the rotation structure 35, and the second stopper structure 37b is located on the side of the second connection structure 36b away from the rotation structure 35. When the touch panel 31 moves from the initial position to the triggering position, the first end 331 of the first linkage unit 33a can rotate in a direction away from the touch panel 31 relative to the position where the first linkage unit 33a is connected to the bracket 34, and the second linkage unit 33b The second end 332 can rotate in a direction away from the touch panel 31 relative to the position of the bracket 34 connected to the second linkage unit 33b.

In this way, when the touch panel 31 moves from the initial position to the triggering position, interference between the linkage component 33 and the touch panel 31 can be effectively avoided. On the one hand, the reliability of the touch panel assembly 3 can be improved, and on the other hand, there is no need to perform the first step. A gap is reserved between the connection position of the linkage unit 33a and the second linkage unit 33b and the touch panel 31, thereby reducing the design difficulty of the touch panel assembly 3 and at the same time reducing the thickness of the touch panel assembly 3 in the thickness direction of the keyboard host 200. The size is conducive to realizing a thin and light design of the keyboard host 200, and for the technical solution in which the battery 55 of the electronic device 1000 is located below the touch pad assembly 3, the touch pad assembly 3 in the embodiment of the present application can be used without increasing the size of the keyboard host 200. On the premise of maintaining the overall thickness, the thickness and size of the battery 55 are increased to improve the battery life of the electronic device 1000.

Please refer to FIG. 13 , which is a simplified schematic diagram of the touch panel 31 of the touch panel assembly 3 shown in FIG. 11 moving from the trigger position to the initial position. Among them, the touch panel 31 and the linkage component 33 shown by the solid lines in FIG. 13 are in the triggering position, and the touch panel 31 and the linkage component 33 shown by the dotted lines are in the initial position. The support bracket 32 is not shown in FIG. 13 .

After the touch panel 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 panel 31, the trigger switch 3121 resumes its deformation, and the touch panel 31 is under the elastic force of the trigger switch 3121. Moving upward toward the initial position, the first linkage unit 33 a and the second linkage unit 33 b are driven by the touch panel 31 to move upward.

Please refer to Figure 11 in conjunction with Figure 13. Since the first stopper structure 37a limits the movement of the first linkage unit 33a in the Z-axis direction, the second stopper 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 uses the first connection position P1 as the rotation fulcrum to rotate counterclockwise relative to the touch panel 31 and the bracket 34, and the second connection position P2 is opposite to the touch panel 31 and the bracket 34. The touch panel 31 moves in the first direction away from the second linkage unit 33b, and the first connection position P1 moves in the first direction toward the second linkage unit 33b relative to the bracket 34. At the same time, the second linkage unit 33b The third connection position P3 is used as the rotation fulcrum to rotate clockwise relative to the touch panel 31 and the bracket 34. The fourth connection position P4 moves relative to the touch panel 31 in the first direction away from the first linkage unit 33a. The third connection position P3 The relative bracket 34 moves in the first direction toward the first linkage unit 33a. In this way, through the cooperation of the first linkage unit 33a and the second linkage unit 33b, the touch panel 31 can smoothly move from the trigger position to the initial position.

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 by some embodiments of the present application.

Please refer to FIG. 14 , which is a perspective view of the support bracket 32 in the touch panel assembly 3 shown in FIG. 10 . The support bracket 32 is a frame structure. The outer contour shape of the support bracket 32 is adapted to the shape of the touch panel 31 . Exemplarily, the support bracket 32 is a rectangular frame structure.

Specifically, please refer to FIG. 14 . The support bracket 32 includes opposite first short side portions 321 and second short side portions 322 , and opposite first long side portions 323 and second long side portions 324 . The extending direction of the first long side portion 323 and the second long side portion 324 is parallel to the X-axis, and the extending direction of the first short side portion 321 and the second short side portion 322 is parallel to the Y-axis. The support bracket 32 is formed by sequentially connecting and enclosing a first short side portion 321 , a first long side portion 323 , a second short side portion 322 , and a second long side portion 324 . A through hole 325 is defined between the first short side portion 321 , the first long side portion 323 , the second short side portion 322 and the second long side portion 324 . The through hole 325 may be a rectangular hole, a square hole, a circular hole, an elliptical hole, etc.

Please continue to refer to FIG. 14 . The support bracket 32 includes a top surface 326 and a bottom surface 327 that are opposite in the thickness direction. The top surface 326 is used for fixed connection with the touch panel 31 . The thickness direction of the support bracket 32 is parallel to the Z-axis.

The support bracket 32 may be an integral structural member, or may be assembled from multiple parts through bonding, snapping, threaded connection, etc.

The support bracket 32 can be used to enhance the rigidity of the touch panel 31 , thereby reducing deformation and collapse when the user presses the touch panel 31 . It can be understood that if the touch panel 31 is sufficiently rigid, the support bracket 32 may not be used. In addition, by providing the support bracket 32 , the pressing component can be connected to the linkage component 33 via the support bracket 32 , which can effectively protect the touch panel 31 , avoid damage to the touch panel 31 , and improve the reliability of the touch panel assembly 3 .

Please refer to FIGS. 15 and 16 . FIG. 15 is a schematic assembly diagram of the support bracket 32 and the touch panel 31 in the touch panel assembly 3 shown in FIG. 10 . FIG. 16 is a cross-sectional view along line E-E of the schematic assembly diagram shown in FIG. 15 .

Specifically, the top surface 326 of the support bracket 32 is fixedly connected to the side surface of the circuit board 312 that is away from the touch substrate 311 . For example, the top surface 326 of the support bracket 32 is adhesively connected to a side surface of the circuit board 312 away from the touch substrate 311 .

Referring to FIG. 16 , the trigger switch 3121 on the touch panel 31 is directly opposite to the through hole 325 . In this way, by setting the support bracket 32 as a frame structure, the through hole 325 can be formed on the support bracket 32. On the one hand, the support bracket 32 can be prevented from interfering with the trigger switch 3121 while ensuring the support effect of the support bracket 32. On the other hand, the support bracket 32 can be prevented from interfering with the trigger switch 3121. On the premise of ensuring the supporting function of the support bracket 32, the material used for the support bracket 32 can be reduced, which is beneficial to reducing the weight of the support bracket 32, thereby reducing the overall weight of the touch panel assembly 3.

Please continue to refer to FIG. 16 . The area enclosed by the outer contour of the support bracket 32 is larger than the area of the touch panel 31 . That is to say, the orthographic projection of the touch panel 31 on the plane where the support bracket 32 is located is located within the outer contour of the support bracket 32 . In this way, the supporting effect of the support bracket 32 can be ensured and the edge of the touch panel 31 can be prevented from warping.

Since the structural strength of the support bracket 32 directly determines the support effect, in order to ensure the structural strength of the support bracket 32 , the thickness of the support bracket 32 can be increased. However, this will increase the overall thickness of the touch panel assembly 3 . In order to avoid this problem, a material with greater rigidity can be selected to make the support bracket 32 to take into account both structural strength and thickness. In some embodiments, support bracket 32 is a piece of metal. For example, the support bracket 32 can be made of stainless steel, aluminum, etc.

Please refer to FIGS. 17 and 18 . FIG. 17 is a perspective view of the linkage component 33 in the touch panel assembly 3 shown in FIG. 10 . FIG. 18 is an exploded view of the linkage component 33 shown in FIG. 17 .

The first linkage unit 33a and the second linkage unit 33b respectively include a fixing plate 333 and two connecting pieces 334. In this embodiment, the structure of the second linkage unit 33b is the same as that of the first linkage unit 33a, and the first linkage unit 33a and the second linkage unit 33b are arranged symmetrically with respect to the YZ plane. The fixing plate 333 is used to connect the support bracket 32 . The fixing plate 333 is flat. In this way, the contact area between the first linkage unit 33a, the second linkage unit 33b and the support bracket 32 can be increased, and the sensitivity of the touch panel assembly 3 can be improved.

For example, the fixing plate 333 is in the shape of a rectangular plate. The thickness direction of the fixed plate 333 is parallel to the Z-axis. That is, the fixing plate 333 is formed into a flat plate structure parallel to the touch panel 31 . In this way, the first linkage unit 33a and the second linkage unit 33b are conveniently connected to the support bracket 32, which can reduce the assembly difficulty of the touch panel assembly 3 and improve the assembly efficiency.

It can be understood that in other embodiments, the thickness direction of the fixing plate 333 may not be parallel to the touch panel 31 . That is, the fixing plate 333 has an inclined plate-like structure.

Please refer to Figures 17 and 18. The connecting member 334 is in a long strip shape. The two connecting parts 334 are both fixed on one side of the fixing plate 333, and the two connecting parts 334 are spaced apart in the second direction. Specifically, both connectors 334 of the first linkage unit 33a are fixedly connected to the side of the fixing plate 333 of the first linkage unit 33a close to the second linkage unit 33b. The two connecting pieces 334 of the second linkage unit 33b are both fixedly connected to the side of the fixing plate 333 of the second linkage unit 33b close to the first linkage unit 33a.

The connecting piece 334 of the first linkage unit 33a and the connecting piece 334 of the second linkage unit 33b are rotationally connected through the rotating structure 35 .

In some embodiments, please refer to FIG. 19 , which is an enlarged view of the region F in the perspective view shown in FIG. 17 . 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 piece 334 of the first linkage unit 33a, and the second sleeve 352 is fixedly connected to the connecting piece 334 of the second linkage unit 33b. The first shaft sleeve 351 is formed with a first shaft hole, and the second shaft sleeve 352 is formed with a second shaft hole, and the second shaft hole corresponds to the first shaft hole. The shaft core 353 is inserted into the first shaft hole and the second shaft hole. In this way, the rotational connection between the connecting piece 334 of the first linkage unit 33a and the connecting piece 334 of the second linkage unit 33b can be realized, with a simple structure and easy assembly.

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 .

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

A second shaft hole is provided on the second sleeve 352 for mating with the shaft core 353. On the one hand, it can avoid directly opening a hole on the connecting piece 334, which can improve the structural strength of the connecting piece 334. On the other hand, The structure of the first linkage unit 33a can also be made the same as that of the second linkage unit 33b, thereby simplifying the mechanism of the linkage component 33. During the processing, a linkage unit is processed, which can be used as either the first linkage unit 33a or the second linkage unit 33b, which greatly reduces the processing cost.

It can be understood that the structure of the rotating structure 35 in this embodiment is not limited to this. For example, please refer to FIG. 20 , which is a schematic diagram of 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 rotating structure 35 is a flexible part. The flexible part is connected between the connecting part 334 of the first linkage unit 33a and the connecting part 334 of the second linkage unit 33b. The thickness of the flexible member is less than the thickness of the connecting member 334 . In this way, by arranging the rotating structure 35 as a flexible part, the structure of the linkage component 33 can be simplified, and the space occupied by the rotating structure 35 can be reduced, which is beneficial to reducing the overall thickness of the touch panel assembly 3 and achieving a thinner and lighter electronic device 1000 design.

It can be understood that the rotating structure 35 can also be other structures, as long as the connecting piece 334 of the first linkage unit 33a and the connecting piece 334 of the second linking unit 33b can be rotatably connected through the rotating structure 35, this application is The structure of the rotating structure 35 is not specifically limited.

Please refer to Figure 22, which is an enlarged view of the D area in the perspective view shown in Figure 21. The first connection part 361 includes a first connection section 3611, a second connection section 3612 and a third connection section 3613. The first connecting section 3611 is fixedly connected to the bottom surface 327 of the support bracket 32 . The first connecting section 3611 is in the shape of a flat plate. Specifically, one end of the first connecting section 3611 is fixedly connected to the bottom surface 327 , and the other end of the first connecting section 3611 extends in a direction away from the top surface 326 .

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 direction of the first connecting section 3611 may be parallel to the Y-axis, and the width direction of the first connecting section 3611 may be parallel to the Z-axis. In other embodiments, the length direction of the first connecting section 3611 may also be parallel to the X-axis.

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

Referring to FIG. 22 , the second connecting section 3612 is fixedly connected to an end of the first connecting section 3611 away from the bottom surface 327 of the supporting bracket 32 . The second connecting section 3612 is flat. 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 accommodation 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 . The transition between the second connecting section 3612 and the first connecting section 3611 can be smooth.

In other embodiments, the second connecting section 3612 may be flat-shaped 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 plate.

Please continue to refer to FIG. 22 . The third connecting section 3613 is provided at one end of the first connecting section 3611 in the length direction. The third connecting section 3613 and the first connecting section 3611 form an L-shaped structure. For example, the third connecting section 3613 is provided on one side of the first connecting section 3611 in the Y-axis direction. The third connecting section 3613 is fixedly connected to the first connecting section 3611. Further, the third connecting section 3613 is fixedly connected to the second connecting section 3612. The third connecting section 3613 is flat. For example, the third connecting section 3613 is in the shape of a rectangular plate. The length direction of the third connecting section 3613 is parallel to the X-axis, and the width direction of the third connecting section 3613 is parallel to the Z-axis. Optionally, the third connecting section 3613 is perpendicular to the first connecting section 3611, and the third connecting section 3613 is perpendicular to the second connecting section 3612.

In some embodiments, the first connecting portion 361 is an integral structural member. That is, the first connecting portion 361 is integrally formed.

Furthermore, the first connecting part 361 and the supporting bracket 32 have an integrated structure. That is, the first connecting part 361 and the support bracket 32 are integrally formed. In this way, the connection strength between the first connecting part 361 and the support bracket 32 can be improved, and the processing technology of the support bracket 32 can be simplified and the cost can be reduced.

Please refer back to FIGS. 17 and 18 . The first linkage unit 33 a and the second linkage unit 33 b are each provided with a second connection part 362 for connecting with the first connection part 361 . The second connecting portion 362 is provided on the fixing plate 333 . Specifically, two second connection parts 362 are provided on the fixed plate 333 of the first linkage unit 33a. The two second connection parts 362 have the same structure and are symmetrical about the XZ plane.

Two second connection parts 362 are provided on the fixing plate 333 of the second linkage unit 33b. The second connection portion 362 on the second linkage unit 33b and the second connection portion 362 on the first linkage unit 33a are symmetrical with respect to the YZ plane.

Please refer to Figure 23, which is an enlarged view of the H region in the exploded view shown in Figure 18. The second connection part 362 includes a second tab 3621. The second tab 3621 is used to cooperate with the first receiving space 3614. Specifically, part of the first accommodation space 3614 is used to accommodate the second tab 3621. That is to say, the first accommodation space 3614 is not occupied by the second tab 3621. In this way, the second tab 3621 can movably fit in the first accommodation space 3614, so that the second tab 3621 can be released for the first time. An accommodation space 3614 rotates around a rotation axis parallel to the second direction, and moves in the first direction relative to the first connecting portion 361 . In this way, through the cooperation of the second connection part 362 and the first connection part 361, the first linkage unit 33a and the second linkage unit 33b can be movably connected to the support bracket 32, so that the first linkage unit 33a and the second linkage unit 33b are in When the pressing member moves, it can rotate relative to the pressing member and move in the first direction relative to the pressing member.

In some embodiments, please continue to refer to FIG. 23 . The second connection part 362 also includes a through-hole 3623 provided on the fixing plate 333 . The through-hole 3623 penetrates both sides of the fixing plate 333 in the thickness direction. The second tab 3621 is connected to the inner wall surface of the through opening 3623. The inner wall surface of the through opening 3623 refers to the wall surface of the through opening 3623 facing its own central axis.

For example, the through opening 3623 is generally in the shape of a rectangular opening, and the second latch 3621 is in the shape of a rectangular plate. The second tab 3621 has a first side wall surface 3621a. The first side wall surface 3621a is spaced apart from the inner wall surface of the through hole 3623. In this way, a first side wall surface 3621a and the inner wall surface of the through hole 3623 can be defined. Card hole 3623a. The first clamping hole 3623a is used to cooperate with the first connecting section 3611 of the first connecting part 361.

Please continue to refer to FIG. 23 . The first clamping hole 3623 a is elongated, and the length direction of the first clamping hole 3623 a is consistent with the length direction of the first connecting section 3611 . For example, the length direction of the first clamping hole 3623a is parallel to the Y-axis.

It can be understood that the other side wall surfaces of the second latch 3621 except the first side wall surface 3621a can be fixedly connected to all the inner wall surfaces of the through hole 3623, or the other side wall surfaces of the second latch 3621 except the first side wall surface 3621a can be fixedly connected to the inner wall surface of the through hole 3623. A part of the other side wall surfaces other than the first side wall surface 3621a is fixedly connected to the inner wall surface of the through hole 3623, and another part of the other side wall surfaces of the second latch 3621 except the first side wall surface 3621a is spaced apart from the through hole 3623. set up. The second tab 3621 includes a top surface and a bottom surface that are oppositely arranged in the Z-axis direction, and the side wall surface of the second tab 3621 is located between the top surface and the bottom surface of the second tab 3621 .

In some embodiments, please refer to Figure 23, the second tab 3621 also has a second side wall surface 3621b, and the second side wall surface 3621b is disposed adjacent to the first side wall surface 3621a. Specifically, the second side wall surface 3621b and the first side wall surface 3621a are not coplanar. The second side wall surface 3621b may be located at one end of the first side wall surface 3621a in the length direction. Optionally, the second side wall surface 3621b is perpendicular to the first side wall surface 3621a. The second side wall surface 3621b is spaced apart from the inner wall surface of the through opening 3623. A second clamping hole 3623b is defined between the second side wall surface 3621b of the second latch tongue 3621 and the inner wall surface of the through hole 3623. The second clamping hole 3623b is elongated, and the length direction of the second clamping hole 3623b can be aligned with the X-axis. parallel. The second clamping hole 3623b is connected with the first clamping hole 3623a. The second clamping hole 3623b and the first clamping hole 3623a form an L-shaped hole. Therefore, at least two side wall surfaces of the second latch 3621 are spaced apart from the inner wall surface of the through-hole 3623, which can improve the elasticity of the second latch 3621 and facilitate the second latch 3621 to extend into the first accommodation space 3614 and connect with the first receiving space 3614. The first accommodation space 3614 cooperates.

In some embodiments, the second clamping hole 3623b can also be used to cooperate with the third connecting section 3613 of the first connecting part 361.

In some embodiments, the second tab 3621 and the fixing plate 333 are an integral structure. That is, the second latch 3621 and the fixing plate 333 are integrally formed. During the processing, the first locking hole 3623a and the second locking hole 3623b can be directly opened on the fixing plate 333 to form the second locking tongue 3621 on the fixing plate 333. The technology is simple and the processing is convenient.

In other embodiments, the second latch 3621 and the fixing plate 333 may also have a separate structure. For example, during the processing, a through-hole 3623 can be opened on the fixing plate 333 first, and then the second tab 3621 can be fixedly connected to the inner wall of the through-hole 3623 by bonding, welding or snapping.

Please refer to Figures 24-25. Figure 24 is an assembly diagram of the support bracket 32 shown in Figure 21 and the linkage component 33 shown in Figure 17. Figure 25 is an enlarged view of the I area in the assembly diagram shown in Figure 24. Please refer to Figure 25. When the first connecting part 361 and the second connecting part 362 are assembled, the first connecting section 3611 is inserted into the first clamping hole 3623a, and the third connecting section 3613 is inserted into the second clamping hole 3623b. The second tab 3621 is located in the first accommodation space 3614.

In this way, the connection reliability between the second connecting part 362 and the first connecting part 361 can be improved, and the second latch 3621 can be prevented from slipping out of the first accommodating space 3614. Furthermore, the first snap hole 3623a cooperates with the first connecting section 3611 to limit the displacement of the first linkage unit 33a in the X-axis direction, and the second snap tongue 3621 cooperates with the first accommodation space 3614 to limit the first The displacement of the linkage unit 33a in the Z-axis direction can be limited by the third connecting section 3613 and the second clamping hole 3623b, which can limit the displacement of the first linkage unit 33a in the Y-axis direction, which is beneficial to improve the performance of the touch panel 31 and the support bracket 32 Smoothness of movement.

Specifically, please refer to Figure 26, which is a cross-sectional view of the assembly diagram shown in Figure 24 at line F-F. The second tab 3621 is located between the bottom surface 327 of the support bracket 32 and the second connecting section 3612.

Please refer to Figure 27, which is an enlarged view of the J portion area in Figure 26. The size d1 of the first clamping hole 3623a in the first direction (that is, the X-axis direction) is larger than the size d2 of the first connecting section 3611 in the first direction. In this way, when the touch panel 31 and the support bracket 32 move between the initial position and the triggering position, the movement of the first linkage unit 33a in the first direction relative to the touch panel 31 and the support bracket 32 is facilitated, and the first connection part 361 is also facilitated. Assembly with the second connecting portion 362 can reduce assembly difficulty.

Please continue to refer to Figure 27. The first clamping hole 3623a has a first inner wall surface 3623a1. The first inner wall surface 3623a1 is opposite to the first side wall surface 3621a of the second latch 3621. 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 can engage with the first connecting section 3611 to restrict the first linkage unit 33a from continuing to move away. The direction of the second linkage unit 33b moves. When the first linkage unit 33a moves a certain distance in the first direction away from the second linkage unit 33b, the first side wall surface 3621a of the second latch 3621 can engage with the first connecting section 3611 to limit the first linkage unit 33a. The linkage unit 33a continues to move in a direction 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 clamping hole 3623a can engage with the first connecting section 3611 to limit the first linkage unit 33a. The linkage unit 33a continues to move toward the second linkage unit 33b. In this way, the displacement of the first linkage unit 33a in the first direction (that is, the X-axis direction) can be limited by the first clamping hole 3623a cooperating with the first connecting section 3611.

Please continue to refer to FIG. 27 . The size d3 of the second tab 3621 in the moving direction of the touch panel 31 (that is, the Z-axis direction) is smaller than the size d4 of the first accommodation space 3614 in the moving direction of the touch panel 31 . In this way, when the touch panel 31 and the support bracket 32 move between the initial position and the triggering position, the second tab 3621 is facilitated to rotate in the first accommodation space 3614, thereby allowing the first linkage unit 33a to move relative to the touch panel 31, The support bracket 32 rotates.

Please refer to 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 a certain angle in the clockwise direction, the bottom surface 327 of the support bracket 32 can contact with the second latch. 3621 is a stop fit to restrict the first linkage unit 33a from continuing to rotate in the clockwise direction. When the first linkage unit 33a rotates a certain angle in the counterclockwise direction, the first top surface 3262a can engage with the second latch 3621 to restrict the first linkage unit 33a from continuing to rotate in the counterclockwise direction. In this way, the first accommodation 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 touch panel 31 and the support bracket 32 in the Z-axis direction.

Please refer back to Figure 25. The third connecting section 3613 is inserted into the second clamping hole 3623b. The dimension d5 of the third connecting section 3613 in the Y-axis direction is substantially equal to the dimension d6 of the second clamping hole 3623b in the Y-axis direction. In this way, by cooperating with the third connecting section 3613 and the second clamping hole 3623b, the first linkage unit 33a can be limited in the Y-axis direction, thereby preventing the touch panel 31 and the support bracket 32 from being between the initial position and the triggering position. During the movement, the first linkage unit 33a shakes, which can improve the smoothness of the movement of the touch panel 31.

It can be understood that in other embodiments, the first connecting part 361 may not include the third connecting section 3613. In this case, the first connecting portion 361 may be L-shaped.

Please refer to FIG. 28 , which is a perspective view of the bracket 34 in the touch panel assembly 3 shown in FIG. 10 . The bracket 34 includes a bracket body 341 that includes a first surface 3411 and a second surface 3412 that are opposite to each other. The bracket body 341 may be formed into an annular frame structure. Exemplarily, the bracket body 341 is a rectangular frame. In other embodiments, the bracket body 341 may also be formed into a flat plate structure.

Please refer to FIG. 29 , which is a schematic assembly diagram of the bracket 34 shown in FIG. 28 and the linkage component 33 shown in FIG. 17 . In this embodiment, the bracket 34 is located on a side of the linkage component 33 away from the touch panel 31 . The stop structure 37 includes a stop portion 371 and a limiting portion 372 . The bracket 34 is provided with a limiting portion 372, and the first linkage unit 33a and the second linkage unit 33b are respectively provided with stop portions 371.

Referring to FIG. 29 , the stopper 371 can be fixedly connected to the fixing 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 away from the rotating structure 35. In the direction from the second linkage unit 33b to the first linkage unit 33a, the stopper portion 371 of the first linkage unit 33a extends obliquely toward the bracket 34, and the stopper portion 371 of the second linkage unit 33b faces away from the bracket 34. direction extends obliquely. The linkage structure 33 has an M-shaped structure. In this way, the stopper 371 and the bracket 34 can be easily engaged.

Optionally, the stopper 371 is plate-shaped. In this way, the rigidity of the stopper 371 can be improved, and the stopper 371 can be prevented from being deformed when the touch panel 31 is pressed.

In some embodiments, the stopper 371 and the fixing plate 333 are an integral structure. That is, the stopper 371 and the fixing plate 333 are integrally formed. In this way, the structure of the linkage structure 33 can be simplified, and at the same time, the connection strength between the stopper 371 and the fixing plate 333 can be improved.

Please refer to Figure 29. The bracket 34 is provided with a plurality of limiting portions 372. Some of the plurality of limiting portions 372 are used to connect with the stopper portions 371 on the first linkage unit 33a. The other part is used to connect with the stopper 371 on the second linkage unit 33b. For convenience of description, the limiting portion 372 used to connect with the stopper portion 371 on the first linkage unit 33a will be called the first limiting portion 372a, and will be used to connect with the stopper portion 371 on the second linkage unit 33b. The limiting part 372 is called the second limiting part 372b.

There are two first limiting parts 372a, and the two first limiting parts 372a are spaced apart in the Y-axis direction. In some embodiments, the two first limiting portions 372a are arranged symmetrically about the XZ plane. There are two second limiting parts 372b, and the two second limiting parts 372b are spaced apart in the Y-axis direction. The first limiting part 372a and the second limiting part 372b are arranged symmetrically with respect to the YZ plane.

Please refer to Figure 30, which is an enlarged view of the P region in the perspective view shown in Figure 29. The limiting part 372 includes a first baffle 3721 and a second baffle 3722.

The first baffle 3721 is fixedly connected to the first surface 3411 of the bracket body 341. The first baffle 3721 may be in the shape of a flat plate. The first baffle 3721 may be disposed perpendicular to the first surface 3411. The length direction of the first baffle 3721 may be parallel to the Y-axis.

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.

Specifically, at least part of the stopper 371 is located in the first limiting space 3724. When the touch panel and the support bracket 32 move between the initial position and the triggering position, the stopper 371 can rotate in the first limiting space 3724 and the stopper 371 can move in the first direction relative to the bracket 34 .

Please refer to Figure 31, which is an enlarged view of the K area in Figure 11. The limiting part 372 includes a first limiting surface 3724a and a second limiting surface 3724b that are oppositely arranged in the moving direction of the pressing member (that is, in the Z-axis direction). In this embodiment, the bracket 34 is located on a 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 member.

The solid line in FIG. 31 shows a schematic diagram of the cooperation between the stopper part 371 and the limiting part 372 when the pressing component is in the initial position. The dotted line in Figure 31 shows a schematic diagram of the cooperation between the stopper part 371 and the limiting part 372 when the pressing component is in the triggering position. When the pressing member is in the initial position, the end of the stopper 371 away from the fixed plate 333 (that is, the free end of the stopper 371) is in stop-fitting fit with 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 . In this way, when the user presses the pressing member and moves the pressing member from the initial position to the triggering position, the stopper 371 always abuts and cooperates with the first limiting surface 3724a under the action of the pressing force, and the first linkage unit 33a and the second The linkage unit 33b respectively uses the position where the stopper 371 is connected to the first limiting surface 3724a as a rotation fulcrum to rotate in the direction away from the pressing member. The first linkage unit 33a and the second linkage unit 33b respectively move in the first direction away from the rotation structure. 35 direction movement.

Please refer to FIG. 32 , which is another schematic diagram of the cooperation between the limiting part 372 and the stopper part 371 shown in FIG. 31 . The solid line in Figure 32 shows a schematic diagram of the cooperation between the stopper 371 and the limiter 372 when the pressing component is in the triggering position. The dotted line in Figure 32 shows the cooperation between the stopper 371 and the limiter 372 when the pressing component is in the initial position. Schematic diagram of the fit of the position 372.

When the user removes the pressing force on the pressing member, the pressing member 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 of the second linkage unit 33b moves upward. The stopper 371 moves upward along with the second linkage unit 33b. When the stopper 371 stops against the second limiting surface 3724b, the first linkage unit 33a and the second linkage unit 33b use the position where the stopper 371 stops against the second limiting surface 3724b as a rotation fulcrum to move closer to the pressing member. The first linkage unit 33 a and the second linkage unit 33 b respectively move in the first direction toward the direction approaching the rotation structure 35 .

In some embodiments, please refer to FIG. 30 in combination with FIGS. 31-32 . In the direction approaching the rotating structure 35 , the second limiting surface 3724b extends obliquely in the direction away from the bracket body 341 . In this way, when the pressing member moves from the trigger position to the initial position, it is convenient for the second limiting surface 3724b to stop and fit with the stopper 371, and during the assembly process, it is easy to assemble the stopper 371 into the first limiter space 3724. , can reduce assembly difficulty and improve assembly efficiency.

Specifically, the third baffle 3723 is fixedly connected to the first surface 3411, and the third baffle 3723 is located on one side of the first baffle 3721 in the length direction. Specifically, the third baffle 3723 may be located on one side of the first baffle 3721 along the second direction (that is, 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 when the touch panel 31 moves between the initial position and the trigger position. Improve the smoothness of the movement of the touch panel 31.

In other embodiments, the limiting part 372 may not include the third baffle 3723.

Referring to Figure 29, in some embodiments, two first limiting portions 372a are spaced apart in the second direction. In this way, the total occupied space of the two first limiting parts 372a can be reduced, and interference between the first limiting parts 372a and other structures of the touch panel assembly 3 can be avoided.

It can be understood that in other embodiments, the two first limiting parts 372a can also be butt connected. In this case, the two first baffles 3721 are connected to each other, and the two second baffles 3722 are connected to each other. In this way, the two first limiting parts 372a can be connected into an integral structure.

When the user presses the touch panel 31 , the trigger bump 340 can squeeze the trigger switch 3121 to trigger the trigger switch 3121 . In some embodiments, the trigger bump 340 may be stamped by a stamping process. The technology is simple and the processing is convenient.

Therefore, by arranging the intersecting first ribs 342 and the second ribs 343 in the bracket body 341, on the one hand, it is convenient to provide the trigger bump 340 for cooperating with the trigger switch 3121 on the bracket 34; on the other hand, the third The first rib 342 and the second rib 343 can enhance the structural strength of the bracket body 341, which is beneficial to improving the overall structural strength of the bracket 34.
