In this solution, a key hole is provided in the housing 1 of the electronic device for penetrating the key cap 3 therethrough. When key operation is needed, a user presses down the key cap 3, and the key cap 3 drives the key triggering part on the key support to move downwards, so that key operation is realized. The key cap 3 is arranged on the top of the key support 5 and penetrates through the key hole of the shell 1, and after the materials of the key cap 3 and the shell 1 are the same, the key cap 3 can be manufactured by using the material of the shell 1 of the electronic equipment, so that the materials are saved, and the color, the texture, the touch feeling and the like of the key and the shell are kept highly consistent.

Alternatively, the top surface of the key cap 3 may be located on the same plane as the outer surface of the housing 1; the key cap 3 can also protrude out of the outer surface of the shell 1, and the exposed part of the key cap 3 is the same as the surface material of the shell 1, so that the color, the texture and the like of the key cap 3 and the outer surface of the shell 1 are consistent, and the appearance is more attractive.

In one embodiment of the present utility model, the housing 1 is fastened to the key holder 5. The utility model adopts a clamping mode, reduces the use of modes such as direct welding or screw connection, and the like, can simplify the disassembly and assembly steps of the keys, and saves the assembly cost.

Preferably, a melting column is arranged on the inner surface of the shell 1, one end of the melting column, which is away from the shell 1, is provided with a buckle 2, and the buckle 2 is clamped with the edge of the key support 5 or a clamping groove arranged on the key support 5; or, be equipped with the melting post on the button support 5, the melting post deviates from the one end of button support 5 and is equipped with buckle 2, buckle 2 and the draw-in groove joint of setting on casing 1 internal surface.

In the two clamping modes, as the volume of the shell 1 is relatively large, the rigidity of the shell 1 can be improved after the melting column is additionally arranged on the shell, the mode of arranging the melting column and the buckle 2 on the shell 1 is preferably selected, in the mode, the melting columns can be arranged in a plurality, the specific number of the melting columns is set according to the size of the key and the stroke of the key triggering part, and the larger the volume of the key cap 3 or the longer the stroke of the key triggering part is, the more the number of the melting columns are arranged; after the shell 1 and the key support 5 are installed, the plurality of melting columns surround the peripheral edges of the key support 5, and the buckles 2 at the tail ends of the melting columns are clamped at the edges of the key support 5 or arranged on the buckles 2 of the key support 5, so that the key support 5 and the shell 1 are relatively fixed.
