Problems solved by technology

[0007] However, the disadvantage of the existing keyboard device 1 is that the keycap 121 of the key structure 12 cannot be evenly supported due to the small contact area with the pushing member 1242. There is a phenomenon of shaking and instability in all directions, which in turn affects the user's hand feeling in operation, especially when the user presses the periphery of the keycap 121, the degree of shaking of the keycap 121 is more obvious

Embodiment Construction

[0109] see image 3 , which is a structural schematic diagram of a keyboard device of the present invention in a first preferred embodiment, for a clearer illustration, image 3 Only a single button structure is drawn in . The keyboard device 2 includes a circuit board 21 and a plurality of key structures 22 arranged on the circuit board 21. These key structures 22 can be classified into general keys, number keys and function keys, etc., which are respectively pressed by the user with fingers. And make the circuit board 21 generate corresponding button signals to the computer, and then make the computer perform corresponding functions, such as general keys for inputting symbols such as English letters, numeric keys for inputting numbers, and function keys for providing various Shortcut functions, such as F1~F12, etc.

Abstract

The invention provides a keyboard device and a key structure thereof, wherein the keyboard device comprises a circuit board and a plurality of key structures. Each key structure comprises a key cap, ahinge element and a base, wherein the hinge element comprises a first side wing portion connected between the key cap and the base, a second side wing portion connected between the key cap and the base, and a bent portion connected between the first side wing portion and the second side wing portion, wherein the thickness of the bent portion is smaller than the thickness of the first side wing portion and the thickness of the second side wing portion; when the key cap moves up and down relative to the circuit board, the bending angle of the hinge element is changed, and the relative positionbetween the first base convex axis of the base and the first receiving through hole of the first side wing portion is also changed.

Description

technical field [0001] The invention relates to the field of input devices, in particular to a keyboard device. Background technique [0002] The common input devices around the computer include a mouse device, a keyboard device 1 and a trackball device, among which the keyboard device 1 can be used for users to directly input characters and symbols into the computer, so it is highly valued. [0003] First illustrate the structure and function of existing keyboard device 1, please refer to Figure 1 ~ Figure 2 , figure 1 It is a structural schematic diagram of an existing keyboard device, figure 2 for figure 1 The schematic diagram of the mechanical switch of the keyboard device shown after the keycap is pressed. The keyboard device 1 includes a plurality of mechanical key structures 12 and a circuit board 11, each mechanical key structure 12 includes a keycap 121 and a mechanical switch 124 arranged between the keycap 121 and the circuit board 11, and the mechanical s...
