Problems solved by technology

However, the scissor-type bracket usually requires more joints, and the joints also need to add a solid rotation axis. Such a button structure not only increases the difficulty of assembly, but also complicates its own structure.

Embodiment Construction

[0063] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0064] Certain terms are used in the specification and subsequent claims to refer to particular elements. Those of ordinary skill in the art will appreciate that manufacturers may use different names for the same element. This specification and subsequent patent applications do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Includes" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". Furthermore, the terms "coupled" or "connected" include any direct or indirect means of electrical or structural connection. Therefore, if it is described in the text that a first device is coupled / connect...

Abstract

The invention provides a key structure which comprises a base plate provided with a first supporting portion and a second supporting portion, a key cap capable of vertically moving between a first position and a second position relative to the base plate, a first connecting rod rotatably in abutting connection with the first supporting portion to form a first contact shaft, and a second connecting rod rotatably in abutting connection with the second supporting portion to form a second contact shaft, wherein one end of the first connecting rod is connected with the key cap in a slidable mode, one end of the second connecting rod is connected with the key cap in a slidable mode, the other end of the first connecting rod and the other end of the second connecting rod are rotatably clamped with each other to form a third contact shaft, and the third contact shaft is located between the first contact shaft and the second contact shaft. By utilizing the structure, the connecting rods are subjected to abutting connection in a line contact mode, and the connecting rods and the base plate are subjected to abutting connection in a line contact mode, so that solid rotating shafts added at the element connecting positions are omitted, the thickness of the whole key structure is further decreased, the element number is decreased, and the key structure is simplified.

Description

technical field [0001] The present invention relates to a button structure, especially a button structure that does not need to add an additional physical rotating shaft. Background technique [0002] As far as current personal computer usage habits are concerned, the keyboard is one of the indispensable input devices for inputting characters, symbols or numbers. Not only that, but all consumer electronic products in daily life or large-scale processing equipment used in the industry need to be equipped with a key structure as an input device to operate the above-mentioned electronic products and processing equipment. [0003] The conventional key mainly includes a base plate, a key cap and a lifting support device to connect the base plate and the key cap. Since the keycap needs to be able to move up and down stably to provide the function of pressing and triggering the switch, in the prior art, a scissor-type bracket is often used as the lifting support device. However, ...
