Title:

KEYBOARD ASSEMBLY, DEVICE FRAME AND ELECTRONIC DEVICE

Document Type and Number:

WIPO Patent Application WO/2022/037277

Kind Code:

A1

Abstract:

The present application provides a keyboard assembly, comprising a keyboard substrate which comprises multiple keycaps and multiple lifting supports. The keycaps are connected to the keyboard substrate through the lifting supports. The keyboard substrate is connected to a bottom plate and a top plate, the bottom plate comprises a key accommodating slot having an inclined recess surface, the lifting supports are positioned in the key accommodating slot, and one ends of the lifting supports are abutted against the inclined recess surface and can slide on the inclined recess surface. When being rotated to a first set position, the top plate drives the keyboard substrate to move such that the lifting supports slide in a first direction on the inclined recess surface and the keycaps descend together with the lifting supports. When being rotated to a second set position, the top plate drives the keyboard substrate to move such that the lifting supports slide in a second direction on the inclined recess surface, the keycaps ascend along with the lifting supports, and the key travel is increased. The present application also relates to a device frame and an electronic device. The keyboard assembly provided in the present application is thin, the key travel is long, the overall structure is simple, and the manufacturing cost is low.
