Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Referring to fig. 1, 2 and 3, an embodiment of the key device for reducing wobble according to the present invention includes a key cap 2, a scissor-foot unit 3, and a base 4.

The scissor unit 3 is arranged below the keycap 2, and the scissor unit 3 comprises an outer frame 31 and an inner frame 32 which is positioned in the outer frame 31 and is in cross pivot joint with the outer frame 31.

The outer frame 31 has an upper outer frame 311 adjacent to the keycap 2, a lower outer frame 312 spaced apart from the upper outer frame 311, and an outer protrusion 313 extending downward from the lower outer frame 312.

The inner frame 32 has an upper inner frame strip 321 adjacent to the key cap 2, a lower inner frame strip 322 spaced apart from the upper inner frame strip 321, and an inner protrusion 323 extending downward from the lower inner frame strip 322.

The base 4 includes a frame body 41, an outer limiting hole 42 located on the frame body 41 and used for the outer protrusion 313 to penetrate so as to limit the outer protrusion 313 to move up and down, an inner limiting hole 43 located on the frame body 41 and used for the inner protrusion 323 to penetrate so as to limit the inner protrusion 323 to move up and down, an outer frame protrusion 44 protruding upward from the frame body 41 and used for supporting the lower outer frame bar 312, and an inner frame protrusion 45 protruding upward from the frame body 41 and used for supporting the lower outer frame bar 322.

The outer frame protrusions 44 are adjacent to the outer limiting holes 42, and the inner frame protrusions 45 are adjacent to the inner limiting holes 43.

The upper outer frame strip 311, the lower outer frame strip 312, the upper inner frame strip 321 and the lower inner frame strip 322 extend along a left-right direction X, and define a central axis L perpendicular to the left-right direction X and passing through the center of the scissor unit 3, the outer frame protrusions 44 and the outer limiting holes 42 are correspondingly located on one side of the central axis L along the left-right direction X, and the inner frame protrusions 45 and the inner limiting holes 43 are correspondingly located on the other side of the central axis L along the left-right direction X.

Referring to fig. 3, 4 and 5, when the key cap 2 is pressed, the upper outer frame strip 311 and the upper inner frame strip 321 (see fig. 2) are linked by the key cap 2, so that the outer frame 31 and the inner frame 32 pivot relatively, so that the upper outer frame strip 311 and the upper inner frame strip 321 are respectively adjacent to the lower inner frame strip 322 and the lower outer frame strip 312, and at this time, since the outer protrusion 313 and the inner protrusion 323 respectively penetrate and are limited by the outer limiting hole 42 and the inner limiting hole 43, the outer frame 31 and the inner frame 32 do not shake, so that the key cap 2 can be stably pressed down, and the pressing down action is completed.

In addition, when the outer frame 31 and the inner frame 32 pivot relative to each other, the lower outer frame strips 312 and the lower inner frame strips 322 rotate relative to the base 4, and at this time, both ends of the lower outer frame strips 312 and the lower inner frame strips 322 contact the base 4 to form fulcrums, and the outer frame protrusions 44 and the inner frame protrusions 45 also form fulcrums to support the lower outer frame strips 312 and the lower inner frame strips 322, respectively, so that structural strength can be improved, and the lower outer frame strips 312 and the lower inner frame strips 322 are not bent and deformed, thereby ensuring durability.

As described above, the outer protrusions 313, the inner protrusions 323, the outer restriction holes 42, and the inner restriction holes 43 are provided, so that the outer protrusions 313 and the inner protrusions 323 can only move up and down, and the wobbling phenomenon can be reduced, and the outer frame protrusions 44 and the inner frame protrusions 45 can improve the structural strength and ensure the durability, thereby achieving the object of the present invention.
