Key structure

Abstract

The invention discloses a key structure, which comprises a bottom plate, a key cap, a lifting mechanism, a moving member, a linkage support and a magnetic suction member. The lifting mechanism is connected with the bottom plate and the key cap. The moving member is arranged in a sliding manner with respect to the bottom plate. The linkage support has a pivot part, a magnetic suction part and a drive part. The magnetic suction member is arranged on the bottom plate and can generate a magnetic suction force with the magnetic suction part. When the moving member is located in a first position, the pivot part can be rotatablely arranged on a protruding bench of the moving member, and the magnetic suction force drives the key cap to move away from the bottom plate through the linkage support; and when the moving member moves from the first position to a second position, the protruding bench is away from the lower position of the pivot part, so that the pivot part breaks away from the protruding bench and moves downward, and the key cap moves towards the bottom plate. According to the key structure, the key cap can still sink for easy storage even when not pressed; and the key cap restoring force is not generated by an elastic structure, so that the problem that elasticity is influenced since the elastic member may be permanently deformed in the prior art does not occur.

Description

technical field [0001] The invention relates to a magnetic suction key structure, in particular to a magnetic suction key structure in which a key cap can be sunk for storage. Background technique [0002] Traditional notebook computer keyboards do not have a sinking storage design, so whether the computer screen is opened or closed, the keycaps remain at the same height (unpressed position), so the traditional keyboard has a fixed height. For a notebook computer, when the user does not need to use the notebook computer, the user will close the screen. Since the traditional keys cannot be sunk for storage, the screen may collide with the keys and be damaged. In addition, the keys that cannot be sunken and stored take up more space, which limits the thinning of the notebook computer. In addition, if the button structure is designed to provide the keycap recovery force through an elastic member (such as a silicone dome), when the keycap is forced to sink for storage, the elas...

Problems solved by technology

For notebook computers, when the user does not need to use the notebook computer, the user will close the screen. Since the traditional buttons cannot be sunken for storage, the screen may collide with the buttons and be damaged.

In addition, the buttons that cannot be sunken and stored take up more space, which limits the thinning of notebook computers

In addition, if the button structure adopts the design of providing the restoring force of the keycap through an elastic member (such as a silicone dome), when the keycap is forced to sink for easy storage, the elastic member will be in a compressed state for a long time in principle. May cause permanent deformation and affect elasticity, which is not conducive to the service life of elastic components
