Abstract

The invention discloses a push-button structure comprising a bottom plate, a key cap, a first bracket and a second bracket, wherein the first bracket and the second bracket are mutually in pivot joint and are connected with the key cap and the bottom plate. The key cap is provided with a guide groove, and the guide groove approximately extends towards a first direction; and furthermore, the key cap is provided with a first bottom surface, and the guide groove is provided with a second bottom surface. The first bracket is made from metal material, wherein the first bracket is provided with a sliding end, and a first arc shape part and a second arc shape part are formed in a bending mode, are respectively abutted with the first bottom surface and the second bottom surface and can slide in the guide groove.

Description

technical field [0001] The invention relates to a key structure, in particular to a key structure with a metal bracket. Background technique [0002] See first figure 1 , an existing key structure mainly includes a bottom plate B, a key cap C, an elastic body D, a first bracket L1 and a second bracket L2, wherein the first and second brackets L1 and L2 are pivotally connected to each other, and respectively The bottom board B and the keycap C are movably connected, and the aforementioned elastic body D abuts between the bottom board B and the keycap C. The user can press the keycap C downward, and at the same time, the elastic body D can provide an upward elastic force to return the keycap C to the initial position (such as figure 1 indicated by the arrow in the middle). [0003] Since the traditional first and second brackets L1 and L2 are made of plastic materials, they have disadvantages such as poor structural strength and difficulty in achieving thinness; in view of ...
