Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Referring to fig. 2, 3 and 4, the embodiment of the hollow elastic metal sheet abutting device of the present invention is applied to a touch panel 9, and the hollow elastic metal sheet abutting device includes a bottom plate 3, an elastic metal sheet 4, and four screw locking members 5.

The bottom plate 3 includes a bottom plate body 31, and two lower through holes 32 formed at intervals in the left-right direction X in the bottom plate body 31.

The bottom plate body 31 has two sides 311 oppositely arranged on the outer side of the lower through hole 32 along the left-right direction X, two hook supporting parts 312 oppositely extending upwards and backwards from the sides 311 to respectively shield parts of the lower through hole 32, a central part 313 located between the lower through holes 32, and two connecting parts 314 convexly arranged upwards and arranged at intervals along the front-back direction Y perpendicular to the left-right direction X from the central part 313.

The elastic metal sheet 4 includes an elastic metal plate 41 extending horizontally and used for supporting the touch pad 9, two first upper through holes 42 formed in the elastic metal plate 41 at intervals along the left-right direction X, and two second upper through holes 43 formed in the elastic metal plate 41 at intervals along the front-back direction Y. In this embodiment, the two side profiles of the elastic metal plate 41 are smaller than the profile of the lower through hole 32.

The elastic metal plate 41 has two fastening portions 411 that are disposed on the outer side of the first upper through hole 42 along the left-right direction X and penetrate the lower side of the hook support portion 312 along the left-right direction X, and two fastening portions 412 that are disposed on the outer side of the second upper through hole 43 along the front-back direction Y for fixing the bottom plate 31.

The screw 5 is inserted into the connecting portion 314 and the fixing portion 412, so that the fixing portion 412 is fixed to the connecting portion 314 through the screw 5.

Referring to fig. 3 and 5, when the touch pad 9 is not pressed, the elastic metal plate 41 is supported by the connecting portion 314, so that the locking portions 411 are respectively adjacent to the hook supporting portions 312, and at this time, the bottom center of the touch pad 9 does not contact the elastic metal plate 41.

Referring to fig. 3 and 6, when the center of the touch pad 9 is pressed, the center of the bottom of the touch pad 9 contacts the center of the elastic metal plate 41, and the elastic metal plate 41 can elastically deform after being stressed due to the hollow arrangement of the first upper through hole 42 and the second upper through hole 43, so that when the center of the touch pad 9 is pressed, the elastic metal plate 41 bends downward with the connecting portion 314 as a fulcrum, and triggers when the bottom of the touch pad 9 is sufficiently pressed. It should be noted that, since the touch pad 9 is the prior art and is not the technical key point of the present application, the present application does not further describe the triggering structure and the technology of the touch pad 9.

Referring to fig. 3 and 7, when the touch pad 9 is pressed along one side of the left-right direction X, the locking portion 411 of the elastic metal plate 41 on the pressed side is interlocked to swing from the position of the hook supporting portion 312 on the adjacent pressed side to the direction of the lower through hole 32 on the pressed side, and at this time, the locking portion 411 on the other side is still adjacent to the hook supporting portion 312 to form a fulcrum because of not being pressed, the center of the elastic metal plate 41 is inclined, and the center of the bottom of the touch pad 9 is triggered after contacting the center of the elastic metal plate 41 and receiving sufficient pressure.

Since the two side profiles of the elastic metal plate 41 are smaller than the profile of the lower through hole 32, when any side of the elastic metal plate 41 is pressed, the elastic metal plate can swing towards the corresponding lower through hole 32, so that the overall size can be reduced in height, and in addition, the design that the hook supporting parts 312 extend upwards and backwards in opposite directions enables the clamping parts 411 to extend horizontally without being bent as in the prior art, so that damage can be avoided.

In summary, the lower through hole 32 and the hook supporting portion 312 of the bottom plate 3, and the first upper through hole 42, the second upper through hole 43 and the locking portion 411 of the elastic metal piece 4 are provided, so that the overall size can be reduced and damage can be avoided, thereby achieving the objective of the present invention.
