Key structure and electronic device

Abstract

The invention relates to a key structure and an electronic device and belongs to the technical field of electrons. The key structure comprises a housing, a key cap, an electronic switch, a limiting plate and a rocking bar, wherein the electronic switch is installed in the housing, and an opening is formed in the position, corresponding to the electronic switch, of the housing, the rocking bar comprises a head portion and a rod portion, the rod portion is hinged to the housing, the head portion is provided with a through hole, a key contact is arranged at the position, corresponding to the electronic switch, of the head portion, and the length of the rod portion is greater than or equal to a preset value; a clamping hook corresponding to the through hole is formed in the bottom of the key cap, the key cap is installed in the opening, the clamping hook penetrates through the through hole of the rocking bar, and the bottom of the key cap is attached to the head portion of the rocking bar.Plug pins are arranged at two ends of the limiting plate, a gap is formed between the two plug pins, the plug pins of the limiting plate are inserted into the gap between the clamping hook and the head portion of the rocking bar, and the key contact is located in the gap. By adopting the key structure and the electronic device, the problem is solved that the key structure cannot be normally used.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, in particular to a key structure and electronic equipment. Background technique [0002] Electronic equipment in the field of electronic technology mostly involves a key structure, and the key structure is installed in a casing of the electronic equipment. [0003] The key structure usually includes an electronic switch and a keycap. The electronic switch is installed inside the housing of the electronic device. An opening is provided on the housing at a position corresponding to the electronic switch, and the keycap is installed in the opening. The keycap and the housing are usually clearance fit, that is, the outer peripheral dimension of the keycap is smaller than the opening size, so that there is a gap between the keycap and the housing. In this way, the user indirectly presses the electronic switch by pressing the keycap. [0004] In the process of realizing the present discl...

AI Technical Summary

Problems solved by technology

[0005] The frequency of use of the key structure is relatively high, especially when the user presses the keycap unevenly, the keycap is prone to tilt and shake in the opening, and the keycap will frequently rub against the side wall of the opening, causing the wear of the keycap It is more serious, and then the gap between the keycap and the shell becomes larger. If the gap becomes larger, the keycap is easy to sink and the key is stuck, which makes the key structure unable to use normally.
