Description

CROSS REFERENCE TO RELATED APPLICATIONS The present application is based on, and claims priority from, China Patent Application No. 202422706849.2, filed Nov. 7, 2024, the disclosure of which is hereby incorporated by reference herein in its entirety. BACKGROUND OF THE INVENTION Field of the Invention The present invention generally relates to a button structure, and more particularly to a button structure having a better usage hand feeling and a touch sensing function. Description of Related Art Generally, shoulder keys in a game controller are acted as more frequently used operating keys. The shoulder keys are symmetrically disposed to two opposite sides of a front end of the game controller. The shoulder keys are pressed by index fingers to operate the game controller. The shoulder keys are rebounded to be restored to original positions by resilience forces of the shoulder keys and structure strengths of the shoulder keys. A length of each shoulder key is relatively longer, and a production tolerance and an assembling tolerance are generated between the shoulder keys and other various structures of the game controller, so a distance is formed between the shoulder keys and an electronic component of the game controller when the shoulder keys are pressed downward, and a larger gap is formed between a contacting point of each shoulder key and the electronic component of the game controller. As a result, the shoulder keys have a poor usage hand feeling. A conventional game pad includes a button assembly, a switch assembly and a button bracket. The switch assembly is disposed to the button bracket. The switch assembly and the button assembly are cooperated with each other. The button assembly has a shaft. The button bracket has a button fixing structure. A shape of the button fixing structure is matched with a shape of the shaft. The shaft is buckled in the button fixing structure, so that the button assembly is rotatably connected with the button bracket. However, when the button assembly and the switch assembly are assembled, the button assembly and the switch assembly are cooperated with a zero tolerance, the button assembly and the switch assembly are overly pressed easily. The button assembly is rotatably connected to the button bracket. When the button assembly is pressed downward, different forces are required at the time of pressing different positions of a button body of the button assembly, and a tilt of the button body is caused, so a usage hand feeling is affected. In addition, the button assembly of the conventional game pad lacks a touch sensing function for detecting an approaching finger. Thus, it is essential to provide an innovative button structure, and the button structure has a better usage hand feeling and a touch sensing function.
