Problems solved by technology

[0009] Although based on the above-mentioned design of the opening 2222 and the guide slope 2223, the inner frame 221' can be quickly assembled into the outer frame 222' and can be produced automatically, but if the assembled keyboard device is dropped (such as accidentally dropped fall or the keyboard device needs to pass the reliability drop test before leaving the factory) or is hit by an external force, the shaft 2211' of the inner frame 221' is easily guided along the axis hole 2221' of the outer frame 222' through the above-mentioned specific angle and direction. The inclined surface 2223 slides and slides out from the opening 2222, which will lead to the disintegration of the scissors connection element 22', and further cause the elements in the key structure to be scattered

Embodiment Construction

[0058] see Figure 4 as well as Figure 5 , Figure 4 It is a three-dimensional exploded schematic view of the button structure of the present invention in a preferred embodiment, Figure 5 for Figure 4 Schematic diagram of the structure of the scissor-type connection elements of the key structure shown. The key structure 3 includes a scissors connection element 30, a key bottom plate 31, a keycap 32, a membrane switch circuit 33 and an elastic body 34, and the scissors connection element 30 is located between the keycap 32 and the membrane switch circuit 33, and includes a first frame 301 and the second frame 302 pivotally connected to the first frame 301, so that the second frame 302 can swing relative to the first frame 301. In this preferred embodiment, the first frame 301 and the second frame 302 are respectively inner frames and the outer frame, and the first frame 301 is erected on the inner side of the second frame 302 .

[0059] Moreover, the membrane switch cir...

Abstract

The invention provides a shear-type connecting element and a key structure therewith. The element comprises a first frame and a second frame, wherein the opening of the second frame allows a rotating shaft of the first frame to enter a shaft hole of the second frame, thereby enabling the first frame to be pivoted to the second frame. A blocking structure of the second frame is disposed nearby the opening or between the opening and the shaft hole, so as to enable the rotating shaft to be limited between the blocking structure and the shaft hole. Therefore, the element is easy to assemble, and improves the connection stability of the first and second frames.

Description

technical field [0001] The invention relates to the field of input devices, in particular to a key structure and a scissor-type connecting element applied to a keyboard device. Background technique [0002] The common input devices around the computer include a mouse device, a keyboard device, and a trackball device, among which the keyboard device can be used for users to directly input characters and symbols into the computer, so it is highly valued. [0003] Firstly, the structure and function of the existing keyboard device are described, please refer to figure 1 , which is a schematic diagram of the appearance structure of the existing keyboard device. There are a plurality of keys 10 on the surface of the existing keyboard device 1, and the plurality of keys 10 are classified into general keys, number keys and function keys, etc., which are respectively pressed by the user's fingers to make the keyboard device 1 generate corresponding keys. Key signals are sent to th...
