Problems solved by technology

However, thermocompression fixing requires special thermocompression equipment and requires high operator skills. Once the thermocompression of the button fails, it is difficult to repair and most of them will be scrapped.
Glue fixing also has the problem of difficult repairs, and the strength and durability of glue fixing are limited. Once the keys are loose, it will inevitably affect the normal use and function of the product. In addition, the glue is generally poisonous, which is not conducive to operation and environmental protection.

Embodiment Construction

[0010] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0011] see figure 1 and figure 2 , which is an exploded view of the button structure 100 of the present invention, the button structure 100 includes an upper cover 10 , a button 20 , a circuit board 30 and a support block 40 . A button opening 11 is defined on the upper cover 10 . One end of the button 20 passes through the button opening 11 , and the other end is close to the circuit board 30 . The circuit board 30 is disposed between the button 20 and the supporting block 40 . The button 20 includes a pressing portion 21 and at least one cantilever portion 22 connected to the side of the pressing portion 21 , the cantilever portion 22 is suspended on the circuit board 30 above the support block 40 through at least one support column 50 and between the upper cover 10.

[0012] The pressing portion 21 includes a pressing end 211 and a contact end 212 opposite t...

Abstract

The invention relates to a press key structure comprising an upper cover, a press key, a circuit board and a supporting shoe, wherein the upper cover is provided with a press key opening; one end of the press key is penetrated in the press key opening and the other end is near the circuit board; the circuit board is arranged between the press key and the supporting shoe; the press key comprises a pressing part and at least one cantilever part connected with the lateral of the pressing part; and the cantilever part is suspended between the circuit board and the upper cover above the supporting shoe by at least one supporting pole. In the press key structure, the press key is fixed between the upper cover and the circuit board by adopting the supporting pole, which replaces the traditional mode of hot pressing or dispensing fixing, thereby enhancing the fixing strength of the press key structure, enabling the installation process to be simple and meanwhile facilitating the dismounting repair of the press key structure.

Description

technical field [0001] The invention relates to a button structure. Background technique [0002] Most of the existing buttons adopt a cantilever structure design, that is, a cantilever structure is arranged on one side of the button. The cantilever is generally made of elastic material, which is fixed on the upper cover of the product. When the button is pressed, the cantilever Deformation occurs, and the cantilever can provide a restoring force for the key after the force of pressing the key disappears. [0003] In the existing cantilever buttons, the cantilever is generally fixed on the upper cover of the product by means of thermocompression or glue dispensing. However, thermocompression fixing requires special thermocompression equipment and requires high operator skills. Once the thermocompression of the button fails, it is difficult to repair and most of them will be scrapped. Glue fixing also has the problem of difficulty in repairing, and the strength and durabili...
