Spring type key

Abstract

The invention relates to a spring type key. The key comprises a key frame and a key cap with a plurality of outer corners, wherein the key cap is embedded in an accommodating hole of the key frame; the key also comprises a plurality of strip-shaped elastic arms; each elastic arm comprises an inner fixing arm part, at least one outer movable arm part and at least one corner transition part for connecting the inner fixing arm part with the at least one outer movable arm part; each corner transition part corresponds to each outer corner; and each inner fixing arm part is positioned inside an edge on one side of the bottom of the key cap, and the corner transition part corresponding to the inner fixing arm part extends out of the edge and extends to an edge adjacent to the edge along the corresponding outer corner and is fixed on the key frame through the outer movable arm part. The spring type key has the advantages of lower cost and proper pressing force, and the elastic arms of the spring type key contribute to reducing thickness of the key.

Description

technical field [0001] The invention relates to computer peripheral equipment, in particular to a thin snap-press button for a notebook computer. Background technique [0002] At present, the development of computers and peripheral equipment is all towards light, thin, short and small, and so is the keyboard equipment. How to design thinner keys to reduce the size of the keyboard has always been the goal of the industry. In addition, how to increase the comfort of the keys and make the pressing force more in place is also a direction of the industry's efforts. However, the current general thin keyboards, such as those used for notebook computers, often use scissor feet as the main support structure of the keys, such as figure 1 As shown, an existing key with a scissor foot support structure includes a keycap 71 , a rubber elastic body 72 , a scissor bracket 60 , a conductive layer 73 and a bottom plate 74 . Wherein, the scissors-type bracket 60 includes an upper pivotal po...

Problems solved by technology

However, this kind of button with a scissor foot support structure needs to be provided with multiple pivot structures and an upper fixing part 75 and a lower fixing part 76, the assembly is more cumbersome, and the structure of the parts is more complicated, and the cost of parts and mold opening is higher; In addition, under the same key travel, the thickness of the keys of this design is not easy to reduce (when the key cap 71 is pressed to the lowest position, the scissor bracket 60 still occupies a relatively large thickness), which cannot meet the requirements of today's computers in terms of thinness, lightness, and shortness. requirements
