Problems solved by technology

This structure has restrictions on the thickness of the keycap. In order to meet the needs of the life impact test and the key feel, the thickness of the keycap can only be between 0.4-0.5mm. Too thin cannot meet the life requirements, and too thick will affect the feel.

Embodiment 1

[0041] figure 1 It is a front view of a mobile phone button, and its section view is shown in figure 2 . The elongated keycap 2 includes a first surface and a second surface, and a step is provided on the surface near the elastomer layer (ie, the first surface). The step is closely combined with the silica gel-containing layer 3 . The silicone-containing layer 3 is fixed together with the casing 1 of the mobile phone through a double-sided adhesive layer 4 . The double-sided adhesive layer 4 is only arranged on the part corresponding to the silicone-containing layer 3 and the casing 1 of the mobile phone, and there is no double-sided adhesive layer 4 in other parts. A cavity is formed between the strip-shaped keycap 2 and the layer 3 containing silicone, that is, the key stroke 5 .

[0042] Since the button travel is arranged under the strip-shaped keycap, when the button is pressed, it can move downward to realize the button function. figure 2 The arrows in the are the...

Abstract

The invention discloses mobile phone keys. Each key sequentially comprises an elongated keycap, an elastomeric layer and a double-faced adhesive tape layer, wherein the double-faced adhesive tape layer comprises a first adhesive face, a second adhesive face and a substrate; the first adhesive face and the second adhesive face are respectively adhered on two sides of the substrate; the first adhesive face is used for fixing the substrate with a shell of a mobile phone; the second adhesive face is used for fixing the substrate with the elastomeric layer; the elongated keycap comprises a first surface and a second surface; the first surface is close to one side of the elastomeric layer; the second surface is opposite to the first surface; and a key travel is arranged on the first surface. According to the mobile phone keys, the thickness of the keycap between two pressing positions can be ingeniously reduced.

Description

technical field [0001] The invention relates to a mobile phone key, in particular to a strip-shaped mobile phone key. Background technique [0002] Present mobile phone mainly is divided into two classes, and a class is the mobile phone with button, and a class is the mobile phone of touch screen. For example, Chinese patent application No. 201110255362.1 discloses a mobile phone button. The mobile phone button includes: a button, a silica gel layer and a steel sheet; one surface of the silica gel layer includes a protruding part, a through hole is arranged in the middle of the steel sheet, the protruding part protrudes from the through hole of the steel sheet, and the button is correspondingly arranged on the top of the protruding part surface; also includes double-sided adhesive tape, double-sided adhesive tape includes the first adhesive surface, the second adhesive surface and the substrate, the first adhesive surface and the second adhesive surface are respectively bon...
