TECHNICAL FIELD
[0001] The utility model relates to a key structure, especially to a key structure which simplifies mechanism parts, is simple to assemble, reduces cost and has touch sensing function. BACKGROUND
[0002] In a game controller, the shoulder keys of the game controller are used as operation keys with high frequency. The shoulder keys are symmetrically arranged on both sides of the front end of the game controller. The shoulder keys are usually pressed by the index finger to operate the game controller. The shoulder keys generally rebound from the original position by relying on the rebound force and the strength of their own structure. Because the shoulder keys are long, there is a production tolerance and an assembly tolerance between the shoulder keys and the structures of the game controller, causing a distance between the shoulder keys and the electronic components when the shoulder keys are pressed, resulting in a large gap between the contact points of the shoulder keys and the electronic components, and thus a poor hand feeling of the shoulder keys.

The switch assembly is arranged on the key support and is pressed in cooperation with the key assembly. The key assembly is provided with a rotating shaft. The key support is provided with a key fixing structure matching the shape of the rotating shaft. The rotating shaft is buckled in the key fixing structure to make the key assembly and the key support rotatably connected.

The key sleeve and the spring retaining wall are limited by the compression spring, and the key sleeve and the spring retaining wall can only be arranged in the straight line direction of the compression spring. Therefore, the structure inside the key is relatively complex, the assembly is complex, and the cost is high.
