Problems solved by technology

[0007] However, the absence of scissor-type connection elements creates a new problem: soft key caps are prone to uneven force
For example, when the user touches the corner of the soft key cap, the support force of the soft key cap is insufficient because the soft key cap is made of soft elastic rubber material, and there is no scissor-type connecting element. Otherwise, the touch force applied to the soft key cap cannot be transmitted from the corner to the entire soft key cap
In other words, when the user touches the soft key cap, it is likely to cause uneven force on the soft key cap and fail to generate a key signal, resulting in a malfunction

Embodiment Construction

[0034] In view of the problems in the prior art, the present invention provides a button structure with a thin and light appearance, which can avoid the occurrence of false touches, so as to solve the problems in the prior art. Please also see figure 2 as well as image 3 , figure 2 It is a structural exploded schematic diagram of the button structure of the present invention in a preferred embodiment, and image 3 It is a structural schematic diagram of a soft key cap and a conductive plate in a key structure of the present invention in a preferred embodiment. The key structure 2 includes a soft key cap 21 , a conductive plate 22 , a switch circuit board 23 and an elastic element 24 . The soft key cap 21 is exposed outside the key structure 2 and can be deformed by being pressed. The soft key cap 21 includes a plurality of oblique posts 211 and fixed posts 212 . The conductive disc 22 is fixed on the inner surface 213 of the soft key cap 21 and contacts with a plurality...

Abstract

The invention discloses a key structure, which comprises a soft key cap, a conduction disc, a switching circuit board capable of generating key signals and an elastic element. The conduction disc is fixed on the inner surface of the soft key cap, and is in contact with multiple inner walls of the soft key cap. The switching circuit board is arranged below the conduction disc, and the elastic element is arranged between the conduction disc and the switching circuit board. When the soft key cap is under contact pressure, the conduction disc is twisted due to the deformation of the soft key cap and pushes the inner walls of the soft key cap to transmit contact pressure to the corners of the soft key cap.

Description

technical field [0001] The invention relates to a key structure, in particular to a key structure with a light and thin appearance. Background technique [0002] Common computer peripheral input devices include a mouse, a keyboard, and a trackball. The keyboard can directly input text and symbols to the computer, so it is highly valued by users and input device manufacturers. Among them, the more common one is a keyboard that includes a scissor-type connecting element. [0003] Next, the architecture of the key structure in the keyboard including the scissor-type connection elements is described. see figure 1 , which is a schematic cross-sectional side view of an existing button structure. The existing button structure 1 includes a button cap 11, a scissors-type connecting element 12, an elastic rubber body 13, a membrane switch circuit 14 and a bottom plate 15, and the bottom plate 15 is used to carry the key cap 11, the scissors-type connecting element 12, the elastic r...
