Press key construction capable of regulating stroke

Abstract

The invention relates to a key structure with an adjustable stroke, which comprises a bottom plate with a hook part, a bridge plate is arranged on the bottom plate, a keycap is covered on the bridge plate, a folding frame bridge is erected between the bridge plate and the keycap and comprises a bottom frame and a top frame which are mutually in pin joint, and one end of the top frame is caused to be movably perforated between the hook part which extends to the bridge plate from the bottom plate and the bridge plate. The invention has the advantage that when keyboards with different pressing strokes are prepared, the position of the hook part which corresponds to the frame bridge and the bridge plate only needs to be changed to change the pressing stroke of the keyboards. Compared with the prior art, the key structure saves cost, and moreover, the key structure with an adjustable stroke can supply sufficient key strokes for a cover lifting device when being used for the cover lifting device; when the key structure is folded, the stroke is changed, and consequently, the volume is reduced.

Description

technical field [0001] The present invention relates to a key structure with adjustable stroke, in particular to a key structure which utilizes a bridge and a bottom plate which can be changed in relative position to control the stroke of the key. Background technique [0002] The invention of the computer has brought about the rapid development of human civilization. With the fast calculation and processing functions of the computer, people can handle many complicated tasks that may have taken several days in a short period of time. With the rapid development of technology, In order to make it more convenient for users to use the computer, the size of the computer is also required to be "light, thin, short, and small" to continuously evolve, and then a portable notebook computer, and even a mini computer in the palm are derived. [0003] With the miniaturization of various computer parts, the most important component when using a computer--the thinning and miniaturization o...

Problems solved by technology

[0004] However, in the manufacturing process of the prior art, corresponding to various keyboards with different pressing strokes, it is necessary to design a pair of bridges and bridge plates corresponding to the strokes so that the keyboard can reach the pressing stroke. It is more time-consuming and relatively increases the production cost; moreover, in the keyboard manufacturing technology of notebook computers that are most particular about reducing space to facilitate portability, reducing the stroke of the keys relatively represents a reduction in the use of space, but if the stroke of the keys is too small, it will It causes inconvenience to the user when typing on the keyboard due to the inconspicuous ups and downs of the keys. However, it is still difficult to overcome the problems in the production of notebook computer keyboards in the prior art while reducing the space used by the keyboard and providing the user with an easy-to-operate key. Stroke, thus it can be seen that the prior art has its defective part
