Problems solved by technology

However, as the requirements for thinner and thinner become higher and higher, the structural strength of the scissor-type support made of plastic materials gradually cannot match the user's pressing habits, nor can it meet the user's requirements for pressing stability.

Embodiment Construction

[0080] The present invention provides a button structure, which can be applied to any push-type input device, such as a keyboard, but not limited thereto. The button structure of the present invention is designed by the support of the lifting unit to increase the structural strength, improve the stability and fluency of pressing, improve the convenience of assembly, and increase the design flexibility of the source of pressing feel to meet the needs of users. The structure and operation of each component of the button structure according to the embodiment of the present invention will be described in detail below with reference to the drawings.

[0081] Such as figure 1 As shown, the button structure 10 of the present invention includes a bottom plate 100 , a keycap 200 and a lifting unit 300 . The keycap 200 is disposed above the bottom plate 100 , and the lifting unit 300 is connected between the keycap 200 and the bottom plate 100 to support the keycap 200 to move up and dow...

Abstract

The invention relates to a key structure. The key structure includes a baseboard, a first coupling element, a keycap and a lifting and lowering unit. The baseboard is provided with a first baseboard edge. The first coupling element is arranged on the upper surface of the baseboard in a protruded manner and adjacent to the first baseboard edge. The first coupling element is provided with a first clamp hook top portion and a first clamp hook upright portion. The keycap is arranged above the baseboard. The lifting and lowering unit is connected between the keycap and the baseboard. The lifting and lowering unit includes a first support. The first support is provided with a first flank piece. The first flank piece is provided with a first opening. The first clamp hook upright portion is located in the first opening. The lower surface of the first flank piece is in linear contact with the first baseboard edge so as to form a first spindle for supporting the keycap to be subjected to lifting and lowering movement relative to the baseboard to make the first support can be rotated relative to the first baseboard edge at least. According to the key structure of the invention, the spindle support point is formed through the linear contact between the lifting and lowering unit support and the baseboard to strengthen the stability of the keycap in the lifting and lowering movement relative to the baseboard.

Description

technical field [0001] The invention relates to a key structure, in particular, the invention relates to a key structure with a lifting unit. Background technique [0002] Conventional button structures generally use a restoring unit such as an elastic body to provide power for the keycap to rise and return after being pressed, and use a scissor-like support as a lifting mechanism to support the stability of the keycap lifting. However, the conventional scissor-type support is composed of an inner bracket and an outer bracket, and the inner bracket and the outer bracket must have multiple corresponding connecting mechanisms. Therefore, the inner frame and the outer frame of the conventional scissor-type support are usually made of plastic materials by injection molding, so as to improve the manufacturability and assembly flexibility of the components. However, as the requirements for thinner and thinner become higher and higher, the structural strength of the scissor-type s...
