Problems solved by technology

It can be seen from the above that in order to provide the action space 18 of the button 12, the existing button structure 10 must adopt the convex base 14, but in order to make the button 12 have better operation, it needs to be placed on both sides of the convex base 14. The supporting member 16 is configured, and due to the existence of the supporting member, it o...

Embodiment Construction

[0012] The button module in the preferred embodiment of the present invention is described by taking the application in a mobile phone as an example. The button module includes multiple buttons 30, please refer to figure 2 As shown, each button 30 includes: a keycap 32 , a base 34 , a supporting member 36 , a resisting member 40 and an elastic piece 42 .

[0013] The keycap 32 includes a first surface 32 a and a second surface 32 b opposite thereto, wherein the first surface 32 a is a pressing surface when using the key, and the second surface 32 b is a surface facing the base 34 . In this embodiment, the surface of the keycap 32 is roughly rectangular, but in other embodiments, it may have different shapes.

[0014] The base 34 includes a pressure receiving portion 341 , a bearing portion 342 and a connecting portion 343 . The carrying portion 342 is connected to the pressure receiving portion 341 at a certain angle through the connection portion 343 , wherein the pressure...

Abstract

The invention provides a key module, which at least comprises a key; and the key comprises a keycap, a base, a support element, a resistance element and an elastic piece, wherein the base comprises a compression part and a bearing part connected with the compression part; the keycap is arranged on the compression part; the support element is arranged on the side of the bearing part of the base facing the keycap so as to support the keycap when the keycap is compressed; and the resistance element is arranged between the compression part and the elastic piece to make the elastic piece electrically connected to a circuit board. In the key module, by utilizing the height difference of the compression part and the bearing part of the base, the support element is arranged on the bearing part, and the components are arranged by fully utilizing gaps originally required between keys, so the integral thickness of the key module and an electronic device applying the key module is effectively reduced.

Description

technical field [0001] The invention relates to a button module and an electronic device using the button module. Background technique [0002] see figure 1 , the existing button module includes a plurality of button structures 10 , wherein each button structure 10 includes a button 12 , a convex base 14 , a supporting member 16 , a resisting member 20 and an elastic piece 22 . The convex base 14 has a convex portion. The resisting member 20 is disposed between the elastic piece 22 and the base 14. The base 14 is used to support the button 12 arranged thereon. When the user presses the button 12, the resisting member 20 is used to concentrate the user The power applied to the base 14 further presses down on the shrapnel 22 . [0003] When the button structure 10 is applied to an electronic device (not shown) such as a mobile phone or a personal digital assistant, the button structure 10 is fixed on a circuit board of the electronic device, and the elastic sheet 22 is conn...
