Problems solved by technology

The bracket and the elastic member are usually configured in a compact manner to reduce the installation space required for the button structure, but because the bracket is cross-connected and the silicone round protrusions are arranged in between, the bracket structure has a certain structural complexity
In addition, the silicone round protrusion needs to have a considerable structural volume before it can provide the user with sufficient pressing feedback (that is, the reaction force felt by the user when pressing), so that the required volume of the button structure is limited.
Therefore, unless the stability of keycap movement or the feeling of pressing feedback is reduced or sacrificed, it is difficult for this key structure to be suitable for thin keyboards.

Embodiment Construction

[0036] See Figure 1 to Figure 3 . figure 1 Is a schematic diagram of the key structure 1 according to the first embodiment of the present invention, figure 2 Is the exploded view of button structure 1, image 3 1 edge for the button structure figure 1 Sectional view of center line X-X. The key structure 1 includes a base 10, a key cap 12, a sliding member 14, a guiding mechanism 16 and a transmission mechanism 18. The key cap 12 is disposed on the base 10, and the sliding member 14 is slidably disposed between the base 10 and the key cap 12 The guiding mechanism 16 is used to guide the keycap 12 to move with respect to the base 10 in a limited manner, and the transmission mechanism 18 is used to mutually drive the movement of the sliding member 14 and the keycap 12. Furthermore, in this embodiment, the base 10 includes a bottom plate 102, a movable part 104, and a film circuit board 106. The bottom plate 102 is generally made of metal and is mainly used for structural support....

Abstract

The invention relates to a key structure. The key structure comprises a base, a key cap and a sliding part mechanism arranged between the base and the key cap. The key cap and the sliding part mechanism act interactively to enable the key cap to move vertically relative to the base. The sliding part mechanism is in moving connection with the key cap through a sliding part containing a magnetic portion and interacts with a magnetic portion arranged on the base to generate magnetic attraction force which serves as the return force for the return of the key cap. The sliding part mechanism can also be in moving connection with the key cap through two relatively moving sliding parts, each of which comprises a magnetic portion. The two magnetic portions interact with each other to generate magnetic force to serve as the return force for the return of the key cap. Further, the key cap can be forced to descend by moving the sliding part, so that the key structure can be stored conveniently. According to the key structure, both the key cap actuation stability and enough press feedback feel are provided, and the dilemma of current keyboard design in the prior art is overcome effectively.

Description

Technical field [0001] The present invention relates to a key structure, in particular to a mechanical key structure. Background technique [0002] The general key structure usually provides a mechanism for the key cap to move up and down through a cross-connected bracket, and an elastic member (such as a silicone dome) is provided under the key cap to provide the key cap restoring force to drive the key cap back to its original position (That is, the position when it is not pressed). The bracket and the elastic member usually adopt a compact configuration to reduce the installation space required for the key structure. However, because the bracket is cross-connected and the silicone round protrusions are arranged between them, the bracket structure has a certain structural complexity. In addition, the silicone dome must have a considerable structural volume to provide the user with sufficient pressing feedback feel (that is, the reaction force felt by the user when pressing), s...
