The supporting pad 4 is fixed on the edge of the back of the touch device 1, so that the main deformation amount of the touch device 1 when being pressed decreases from the edge of the touch device 1 to the inside, the possibility of a 'dead zone' occurring when a user presses the touch device 1 can be prevented to the maximum extent, and the touch effect of the touch equipment is improved.

Optionally, the touch device comprises a plurality of support pads 4, the plurality of support pads 4 being fixed at corners of the edge of the touching means 1 and/or at edges of the edge of the touching means. Here, the edge refers to a peripheral portion of the touch device 1, that is, a corner region (i.e., a corner) of the periphery of the touch device 1 may be included, and a non-corner region (i.e., an edge) of the periphery of the touch device 1 may be included.

Specifically, as shown in fig. 1, the touch device 1 is a rectangular plate, and the number of the support pads 4 may be 4, and the 4 support pads 4 are respectively fixed at 4 corners of the touch device 1, so as to support the position of the most corner of the touch device 1. Of course, the support pad 4 may also be disposed near the long and/or short sides of the touch device 1 (e.g., near the midpoint of the long and/or short sides).

Of course, the touch device 1 may have other shapes, such as a circular shape, and the supporting pads 4 may be uniformly supported at the edge of the circular touch device 1.

Alternatively, the touching device 1, the supporting pad 4 and the supporting beam 2 may be fixed by adhesion. Of course, the touching device 1, the supporting pad 4 and the supporting beam 2 may be fixed by other means.

When the pressing force of the user reaches or exceeds a certain value (for example, the force value of normal operation of an ordinary person, generally about 5N), the deformation amount of the deformation region 22 reaches a set value, such as the thickness of the support pad 4, at this time, the touch device 1 contacts the deformation limiting region 24, the sensor 31 still outputs even if the user continues to apply force, but the deformation amount of the deformation region 22 is controlled, so that the electronic components on the touch device 1 can be prevented from colliding with other components and being damaged, and the like, and the deformation region 22 can be prevented from generating irreversible plastic deformation.
