Background technique

With the growth of informatization, information equipment is becoming more and more popular. Taking the most common computer as an example, there are not only various brands and styles on the market, but its tentacles extend to homes, factories, companies, offices and schools. And other places, its level of use has even spread to all walks of life, and it has almost become people's daily necessities. Existing computers, including desktop computers and notebook computers, mostly need to be equipped with a keyboard for users to perform operations such as character input.

In the prior art, a keyboard is composed of a plurality of keys. Please refer to FIG. 1 . FIG. 1 is a schematic cross-sectional view of a conventional button. As shown in Figure 1, the button 7 is mainly composed of a substrate (substrate) 71, a switch (switch) 73, an elastic body (elastic dome) 75, a scissors-shaped supporting member (scissors-shaped supporting member) 77 and A key cap (keycap) 79 constitutes.

Further, the switch 73 is disposed on the substrate 71 ; the elastic body 75 is disposed on the switch 73 ; and the keycap 79 is disposed on the elastic body 75 . Therefore, when the keycap 79 is pressed, it further presses the elastic body 75 , and the elastic body 75 thus triggers the switch 73 .

The scissors-shaped supporting member 77 has a first connecting member 771 and a second connecting member 773 , and the first connecting member 771 is pivotally connected to the second connecting member 773 . The first connecting member 771 and the second connecting member 773 are pivotally connected to the base plate 71 and the keycap 79 respectively. In addition, the first connecting member 771 and the second connecting member 773 have a first cylinder 771 a and a second cylinder 773 a respectively, and the keycap 79 has a guide seat 791 and a seat 793 . When the first connecting member 771 and the second connecting member 773 are connected to the keycap 79, the first column 771a of the first connecting member 771 is pivotally connected to the guide seat 791 of the keycap 79 in a sliding and rotating manner, and The second column 773 a of the second connecting member 773 is rotatably disposed in the seat 793 of the keycap 79 .

In addition, when assembling the key 7 in the prior art, the keycap 79 must be inclined at a specific angle so that the opening of the guide seat 791 is aligned with the first column 771 a of the first connecting member 771 . Next, push the keycap 79 to slide the first column 771 a of the first connecting member 771 into the guide seat 791 . Then, the seat 793 of the keycap 79 is aligned with the second column 773 a of the second connection member 773 and pressed down, so that the second column 773 a is engaged in the seat 793 .

As mentioned above, because the structure of the existing scissors-shaped supporting member is complicated, its manufacturing cost cannot be reduced. During the assembling process, since the keycap must be tilted at a specific angle to be combined with the first connecting member, it will cause inconvenience in assembling, so that the assembling time cannot be shortened. It is also easy to cause damage to the first cylinder or the guide seat due to the negligence of the assembler. In addition, since there are usually tolerances in the manufacture and assembly of each component, when the user applies an improper force (for example, the user pushes one end of the keycap), the first cylinder often dislodges from the guide seat of the keycap. The opening slides out of the guide, causing the key to malfunction.
