Keyboard automatic expansion and folding method and lifting key

Abstract

The invention discloses a lifting key and an expansion and folding method. When a cover body or a handle is closed, the key is in a compressed state, the cover body or the handle of the device is opened, the cover body or the handle releases a traction mechanism, and a movable plate is driven by self elasticity of the key to move; after the movable plate moves, the locking state between the movable plate and an X balance frame is released, the X balance frame is unfolded under effects of a reset mechanism, and the key is restored to a normal height; the cover body or the handle is slowly closed, a traction mechanism pulls the movable plate under effects of the cover body or the handle, the movable plate moves backwards to the initial position, the movable plate and the X balance frame areclamped at the time, and the key changes to a compressed state. According to the automatic lifting key, the key can be automatically unfolded when opening, the key is automatically retracted when closing, the space height is small when closing, and a laptop or a Bluetooth keyboard is thinner and easier to carry.

Description

technical field [0001] The invention relates to the field of keyboard keys, in particular to a keyboard automatic telescopic folding method and a lifting key. Background technique [0002] A keyboard is an instruction and data input device used to operate equipment, and also refers to a group of function keys arranged to operate a machine or equipment through the system. Existing notebooks are getting thinner and thinner, and the requirements for the travel distance of the keyboard keys are becoming more and more stringent. However, if the travel distance of the keys is too short, it will seriously affect the tapping experience of the user, and it is also easy to accidentally touch. In order to ensure the tapping experience of the keys, the general tapping stroke needs to be 2.5-4.5cm, plus the thickness of the keys and the PCB board, the thickness of a keyboard will exceed 4.5cm, which will make the notebook thicker and cannot meet the growing needs of customers. Demand fo...
