The frame member includes a frame body surrounding the main shell member and the keycap member and disposed on the key module, and a stopper extending from the inner side of the frame body to the keycap member and located above the limiting flange Stop flange. Since the stop flange of the frame member is located above the limit flange of the main shell member to block the main shell member, the keycap member can be easily separated from the main shell member when pulled by an external force, thereby avoiding the scissor foot module The key module is pulled by the main shell in conjunction with the key module, resulting in a risk of damage.

Description

Keycap device

This model relates to a keyboard component, especially a key cap device.

An existing key device is suitable for installation on a keyboard. The key device includes a membrane circuit board, an elastic rubber arranged on the membrane circuit board, a scissor foot arranged on the membrane circuit board and surrounding the elastic rubber, and A key cap is clamped on the scissor foot and located above the elastic rubber. When the key cap is pressed down, the elastic rubber will be compressed and touch the film circuit board to generate a pressing signal. When the key cap is released, the elastic force of the elastic rubber makes the key cap return upward to its original position.

However, because the keycap is stuck on the scissor leg, when the keycap needs to be replaced, the scissor leg and the film circuit board will be pulled together when a force is applied to the keycap. If improper force is applied, the scissors may be easily damaged. Foot or the film circuit board. Moreover, when the keyboard is impacted or the key device is pulled by an external force and the keycap is separated from the scissor feet, it is not easy for the user to reassemble and restore the keycap.

Therefore, the object of the present invention is to provide a keycap device which can avoid damage to the component linked with the keycap when the keycap is pulled.

Therefore, the new keycap device is suitable for being installed on a keyboard. The keycap device includes a key module, a scissor foot module, a main shell, a keycap, and a frame.

The key module is arranged on the keyboard. The scissor foot module is detachably arranged on the button module. The main shell includes a shell cover which is clamped on the side of the scissor foot module opposite to the button module, and a limiting flange extending outward from the outer side of the shell cover. The key cap is detachably covered with the shell cover. The frame member includes a frame body surrounding the main shell member and the keycap member and disposed on the key module, and a stopper extending from the inner side of the frame body to the keycap member and located above the limiting flange Stop flange.

The effect of the present invention is that the shell cover can be detachably covered by the key cap, and the stop flange of the frame is located above the limit flange of the main shell. When the key cap is subjected to When external force pulls and moves the main shell member upward, the main shell member will be blocked by the stop flange and cannot continue to move upward and cannot be separated from the key module. Only the key cap member will separate from the main shell member to prevent Avoid the risk of damage to the scissor foot module and the button module being pulled by the main shell in conjunction with each other.

2 and 3, the main housing 3 includes a housing cover 31 that is clamped on the side of the scissor foot module 2 opposite to the button module 1, and a housing cover 31 that extends outward from the outside of the housing cover 31 A ring-shaped limiting flange 32, two first inserts 33 extending downward from the front side of the bottom surface of the housing cover 31 and spaced apart along the left and right direction Y, and two first inserts 33 extending from the bottom surface of the housing cover 31 The second embedding portions 34 extending downward from the rear side and spaced apart in the left-right direction Y.

The cover body 31 has two clamping holes 311 located between the first embedding portions 33 and the second embedding portions 34 and spaced along the left-right direction Y.

Each first embedding portion 33 defines a first embedding groove 331 that is open downward and is detachably clamped by the respective first upper rod portion 213, and each second embedding portion 34 defines a second embedding groove. The portion 34 is open and is provided with the second embedding groove 341 for the respective convex portion 223 to be detachably clamped.

Therefore, two opposite sides of the first frame 21 are pivotally connected to the base plate 11 and the cover body 31 respectively, and two opposite sides of the second frame 22 are pivotally connected to the cover body 31 and the base plate 11 respectively. And one end of the first frame 21 pivotally connected to the base plate 11 corresponds to a side of the second frame 22 pivotally connected to the cover body 31, and one end of the second frame 22 pivotally connected to the base plate 11 corresponds to the first frame 21 is pivotally connected to one side of the cover body 31.

2 to 4, the keycap member 4 detachably covers the shell cover 31 and includes a top wall 41 located above the shell cover 31, and a top wall 41 facing the shell cover 31 from the periphery of the top wall 41 The surrounding wall 42 extends and abuts against the cover body 31, and two buckle portions 43 that extend from the top wall 41 toward the main housing 3 and are detachably clamped in the holes 311.

The frame member 5 includes a frame body 51 that surrounds the main shell member 3 and the keycap member 4 and is fixed on the base plate 11 against the main body, and a frame body 51 that extends from the inner side of the frame body 51 to the keycap member 4 and is located at the An annular stop flange 52 above the limit flange 32 is formed. In this embodiment, the frame main body 51 is fixedly joined to the substrate 11 by thermal melting.

Referring to Figures 4 to 6, the state of this embodiment during operation is described as follows:

When the user presses the keycap member 4, the main housing member 3 is pushed by the keycap member 4 to squeeze the elastic body 13, and the elastic body 13 is compressed so that the main housing member 3 touches the film circuit board 12 to trigger With a pressing signal, when the user releases the key cap 4, the elastic force of the elastic body 13 pushes the main housing 3 to restore the main housing 3 and the key cap 4 to their original positions.

The advantages and effects of the new model are described as follows:

1. The shell cover 31 is detachably covered by the keycap member 4, and the stop flange 52 of the frame member 5 is located above the limit flange 32 of the main shell member 3. When the keycap When the member 4 is pulled by an external force to move the main housing member 3 upward, the main housing member 3 is blocked by the stop flange 52 and cannot continue to move upward, so that the protrusions 223 cannot escape from the second grooves 341. The first upper rod portions 213 cannot be separated from the first insertion grooves 331, so that the main shell 3 remains connected to the scissor foot module 2, and only the key cap 4 will separate from the main shell Piece 3 to avoid the risk of damage to the scissor foot module 2 and the button module 1 being pulled by the main shell 3 in conjunction.

2. When the keycap member 4 falls off due to being pulled, by snapping the buckles 43 of the keycap member 4 into the holes 311 of the main housing member 3, it can be easily and quickly The key cap part 4 is reinstalled back to the main shell part 3.

However, the above are only examples of the present model. When the scope of implementation of the present model cannot be limited by this, all simple equivalent changes and modifications made in accordance with the patent scope of the present model application and the contents of the patent specification still belong to This new patent covers the scope.
