Problems solved by technology

[0002] When the keys on the traditional keyboard are not in use, the keycaps remain in the unpressed position. Therefore, when the traditional keyboard is not in use, it has a certain thickness, which is not conducive to storage or transportation.
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 folded, the screen may collide with the buttons and be damaged.
In addition, the buttons that cannot be folded take up more space, which limits the thinning of notebook computers.
In addition, if the key structure utilizes an elastic member (such as a silicone knob) to provide the design of the keycap’s restoring force, 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, which may Cause permanent deformation and affect elasticity, which is not conducive to the service life of elastic components

Abstract

The invention relates to a key structure. The key structure comprises a bottom plate, a keycap, two supports connected between the bottom plate and the keycap, a first magnetic attraction piece arranged on one support, a movable plate slidably arranged below the bottom plate, and a second magnetic attraction piece corresponding to the first magnetic attraction piece. A magnetic attraction force isgenerated between the first magnetic attraction piece and the second magnetic attraction piece to serve as a restoring force of the keycap. The second magnetic attraction piece can be fixed on the movable plate to be far away from the first magnetic attraction piece along with the movement of the movable plate, so that the magnetic attraction force is reduced for sinking of the keycap, and the key structure can be conveniently stored. The movable plate can comprise a protruding portion which can push one support to rotate towards the bottom plate along with the movable plate, so that the keycap can move towards the bottom plate, and the key structure can be conveniently stored.

Description

technical field [0001] The invention relates to a magnetic suction key structure, in particular to a magnetic suction key structure whose key cap can be sunk for storage. Background technique [0002] When the keys on the traditional keyboard are not in use, the keycaps remain in the unpressed position. Therefore, when the traditional keyboard is not in use, it has a certain thickness, which is not conducive to storage or transportation. For a notebook computer, when the user does not need to use the notebook computer, the user will close the screen. Since the traditional buttons cannot be folded, the screen may collide with the buttons and be damaged. In addition, the buttons that cannot be folded take up more space, which limits the thinning of the notebook computer. In addition, if the key structure utilizes an elastic member (such as a silicone knob) to provide the design of the keycap’s restoring force, when the keycap is forced to sink for easy storage, the elastic me...
