Spring plate device built in retractable keyboard

Abstract

A spring plate device built in a retractable keyboard comprises a base plate, a slide plate with openings and movable support frames corresponding to the openings. Each support frame is formed by pressing four hard sheets on a flexible belt side by side in a winding way. The first hard sheet and the fourth hard sheet are respectively fixedly connected on the slide plate and the base plate part under the corresponding opening. After the slide plate slides, the second hard sheet and the third hard sheet protrude to form an inclined plane. The spring plate device further comprises V-shaped spring plates having the tail parts fixedly connected on the inclined planes. A circuit layer is arranged on the upper surface of each V-shaped spring plate. When the slide plate does not slide, the four hard sheets and the corresponding V-shaped spring plate lie on the slide plate and the base in a flat way. When the slide plate slides in place in a rightward way, the second hard sheet and the third hard sheet protrude to form the inclined plane to drive the corresponding V-shaped spring plate to upwarp. Meanwhile, key caps are supported. The keyboard is then in a normal use state. When the key caps are pressed, the head parts of the V-shaped spring plates can be forcibly bent. When the keyboard is no longer needed, the slide plate moves leftwards and is reset. Then the hard sheets, the V-shaped spring plates and the key caps lie in a flat way again. The thickness of the keyboard is significantly reduced.

Description

technical field [0001] The invention belongs to the technical field of keyboard keys, in particular to a shrapnel device built into a retractable keyboard. Background technique [0002] At present, the thickness of notebook computers is constantly decreasing, and the thickness of each main accessory is also correspondingly reduced, but the thickness of the keyboard, which is one of the computer accessories, basically does not change. This is mainly because of the elastic silicone cap inside the keyboard. The thickness is too large and cannot be changed, so if there is a shrapnel device that can replace the current elastic silicone cap to meet the daily use of the keyboard, and can significantly reduce the thickness of the keyboard, it can save valuable space for electronic devices such as laptops . Contents of the invention [0003] In order to solve the above problems, the present invention provides a shrapnel device built into a retractable keyboard, and the thickness o...
