The present invention provides a button structure improvement, comprising a substrate 10, a keycap 2, at least one link member 3, and a keycap stroke recovery device 4; wherein:

The connecting rod member 3 is connected between the substrate 10 and the keycap 2 to drive the key cap 2 to reciprocate upwardly and downwardly on the substrate 10. Preferably, the substrate 10 is provided with a thin film circuit 12 to After the keycap 2 is pressed, the thin film circuit 12 is touched to achieve the purpose of inputting a key command. In the embodiment of the present invention, the link member 3 may be plural to be evenly carried under the keycap 2, and each of the link members 3 may include a pivot portion 30 pivotally connected to the bottom of the keycap 2, and The pivot portion 31 is pivotally connected to the substrate 10, and the pivot portion 31 can be extended from the two ends of the pivot portion 30 in a non-coaxial manner. In addition, the substrate 10 is provided with a plurality of first pivoting portions 100 for pivoting the pivot portion 31. Each of the first pivoting portions 100 includes a top wall 101, and the top wall 101 extends downwardly to connect to the substrate. a vertical wall 102 on a 10, and a first pivot hole 103 formed by the top wall 101 and the vertical wall 102, so that the pivot portion 31 penetrates into the first pivot hole 103 to be pivoted; and, the bottom of the key cap 2 The second pivoting portion 20 is disposed at a plurality of corners for pivoting the pivoting portion 30. Each of the second pivoting portions 20 includes two arches 21 which are oppositely defined and protruded, and one formed in the two arches The second pivot hole 22 between the blocks 21 is pivotally connected to the pivot portion 30 by the two arches 21 being inserted into the second pivot hole 22.

Accordingly, as shown in the fourth and fifth figures, before the key cap 2 is not pressed, the first angle θ _{1 is} formed between the link member 3 and the substrate 10; and when the key cap 2 is pressed, the connecting rod The member 3 drives the keycap 2 to perform an oblique downward movement, and the keycap 2 thus swings toward one side, so that a second angle θ _{2 is} formed between the link member 3 and the substrate 10. The present invention mainly makes the first angle θ ₁ less than 90 degrees (a limiting portion 104 can be disposed on the substrate 10 to be limited to the other side of the linkage member 3 to keep the angle θ ₁ less than 90 degrees), and The first angle θ _{1 is} greater than 45 degrees, the second angle θ _{2 is} less than 45 degrees, and the 俾 is transmitted through the angular difference between θ ₁ and θ ₂ so that the link member 3 can generate a large stroke during the actuation, so that the button can be pressed. When the keycap 2 is used, a more appropriate power is obtained to produce a better hand feeling. In the embodiment of the present invention, the first angle θ ₁ is 70 degrees, and the second angle θ ₂ is 20 degrees, so the angle difference between the two is 50 degrees, and the angle difference between the two is larger.
