Description

A self-rebound button

technical field

The present invention relates to the technical field of button devices, in particular to a self-rebound button.

Background technique

Most of the keys in the prior art, most of the keys with their own springback structure adopt the key springback method by adding ring-shaped or similar ring-like ribs around the button itself. One end of the rib is fixed on the key base, the other end of the rib is fixed on the key, and the connection between the key and the key base is realized through the rib. In most cases, two or more ribs are used for fixing, but when the key is pressed down, the length of the rib does not change during the pressing down process, but the position changes, so that the fixed end on the key During the depressing process, the design position relative to the button deviates, causing the button to be easily flipped.

Although the current technical solutions adopted by the self-rebound button can meet the self-rebound requirement of the self-rebound button to a certain extent. However, as the button usage time increases, the button itself is prone to plastic deformation. After a period of use, some buttons will sink and cannot rebound and protrude, which seriously affects the product appearance and user experience of using the button.
