It should be further understood that the term "and/or" as used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

Referring to fig. 1, the present invention discloses a touch pad support 10 for a touch pad. The touch pad can be fixed through the touch pad support 10 and receive pressing and clicking operations, the touch pad comprises a touch panel 20, a touch circuit board 30, the touch pad support 10 and a mounting base 40 which are sequentially arranged from top to bottom, the middle part of the touch circuit board 30 comprises a touch module 31, the touch module 31 is arranged towards the touch pad support 10, and the touch module can be a snap dome or other touch modules.

As shown in fig. 2, the touch pad holder 10 includes a frame 11, a fixing plate 12, a linkage plate 13, and an elastic connection plate 14, wherein the fixing plate 12 is fixed to the touch pad, for example, to the mounting base 40, and the fixing plate 12 is opposite to the touch module 31. The linkage plate 13 surrounds the fixed plate 12, i.e., the fixed plate 12 is disposed inside the linkage plate 13. The frame 11 is a square frame, and surrounds the linkage plate 13. The number of the elastic connecting sheets 14 is set to be a plurality, the elastic connecting sheets 14 are used for connecting the frame 11, the linkage plate 13 and the fixing plate 12, the elastic connecting sheets 14 play roles in connection and rebound, and connection points between the elastic connecting sheets 14 and the frame 11, the linkage plate 13 and the fixing plate 12 play roles as fulcrums. In this embodiment, the frame 11 is used to fix the touch circuit board 30 and the touch panel 20, so that the touch panel 20, the touch circuit board 30 and the frame 11 move synchronously. The frame 11, the fixed plate 12, the linkage plate 13 and the elastic connecting sheet 14 are connected by welding. When any position of the touch panel 20 is pressed, the touch panel drives the frame 11 to move, the frame 11 drives the elastic connecting sheet 14 to move, and the elastic connecting sheet 14 drives the linkage plate 13 to move, so that the touch panel 20, the frame 11, the elastic connecting sheet 14 and the linkage plate 13 synchronously move downwards, and the fixed plate 12 is abutted to the touch module 31. It should be noted that, the synchronous downward movement in this document refers to that when any position of the touch panel 20 is pressed, the frame 11 and the touch panel 20 are moved downward integrally under the driving of the frame 11, the elastic connecting sheet 14 and the linking sheet 13, and does not mean that the downward movement distances of the positions of the components are the same.

The elastic connecting sheet 14 is disposed on one side close to the touch circuit board, that is, the frame 11, the linkage plate 13 and the fixing plate 12 are disposed on the same plane, the three are disposed on one side of the elastic connecting sheet 14, and the touch circuit board is disposed on the other side of the elastic connecting sheet 14. Fix monoblock fixed plate 12 in this application, the mode of fixing is more to fixed effect is better, for example as shown in fig. 2, through four screws, fixes respectively in four angular position departments of fixed plate 12.

It should be noted that the impact module 31 is prior art, and the impact module 31 may compress or collapse when the external force reaches an associated threshold. When the user presses the touch panel 20 from the vicinity of the middle position of the touch panel 20, the touch module 31 is easily compressed or collapsed, but when the user presses the touch panel 20 from the peripheral side of the touch panel 20, since only the position of the periphery of the touch panel 20 is pressed, the touch module 31 is pressed less, and the threshold value of the touch module 31 for compression or collapse may not be reached, which may affect the operation of the user. The touchpad support 10 is arranged below the touch circuit board to solve the problem, and under the action of the touchpad support 10, the touch panel 20 realizes approximately parallel movement, and any position of the touchpad is pressed, so that the touchpad drives the frame, the elastic connecting sheet and the linkage plate to move synchronously, and the fixed plate is abutted against the touch module. That is, when the user presses one side of the periphery of the touch panel 20, the other side of the touch panel 20 moves downward, so that the touch module 31 is changed from the non-triggered state to the triggered state of the touch module 31, and the purpose of stabilizing touch is achieved.

When the device is used, a user presses one side (for example, the position close to the edge in the length direction) of the touch panel 20 at the outermost periphery, the pressed side of the touch panel 20 moves downward to drive the touch circuit board 30 and the frame 11 at the same side to move downward together, the elastic connecting sheet 14 at the same side transmits the downward force of the frame 11 to the side close to the linkage plate 13, the linkage plate 13 transmits the downward force from the position close to the pressed position to the other side of the linkage plate 13, so that the force is transmitted to the other side to drive the linkage plate 13 at the other side to move downward, the linkage plate 13 at the other side drives the elastic connecting sheet 14 at the other side to move downward, the elastic connecting sheet 14 at the other side drives the other side part of the frame 11 to move downward, so that the touch circuit board 30 and the touch panel 20 at the other side move downward, and the purpose that the touch circuit board 30 moves similarly in parallel is achieved, so that the impact module 31 on the touch circuit board 30 abuts against the fixing plate 12, and under the supporting force provided by the fixing plate 12, the impact module 31 compresses or collapses to trigger the impact module 31. Since the fixing plate 12 is fixed on the mounting base 40, after the touch module 31 is triggered, the elastic connecting sheet 14 drives the linking plate 13 to rebound under the elastic force of the elastic connecting sheet 14, and the linking plate 13 drives the frame 11 to reset, so that the touch module 31 is triggered when the touch panel 20 is pressed next time.
