Button module and electronic device using the same

Abstract

Disclosed is a key module. The key module comprises a cover board and a key embedded in the cover board, wherein the cover board comprises a touch surface in contact with a user and a bottom surface opposite to the touch surface; a through hole which runs through the touch surface and the bottom surface is formed in the cover board; the shape of the key is matched with that of the through hole to embed the key in the through hole; the hole wall of the through hole clamps the key to prevent the key from sliding from one side, close to the bottom surface, of the through hole; the key module also comprises a fixed sheet; the fixed sheet transversely crosses the through hole, is arranged on the bottom surface and fixed with the key so as to prevent the key from sliding from one side, close to the touch surface, of the through hole. According to the key module provided by the invention, the key can be mounted in the cover board from one side of the touch surface of the cover board and the key can be prevented from sliding from one side, close to the bottom surface, of the through hole; and by virtue of the setting of the fixed sheet, the key can be effectively prevented from sliding from one side, close to the touch surface, of the through hole, so as to dismantle the key from the cover board conveniently.

Description

technical field [0001] The invention relates to a button module and an electronic device using the button module.
