AI Technical Summary

⚠Technical Problem

In existing technologies, adding function keys between keyboard keys takes up extra space, which limits the support design and arrangement of keyboard keys, making it difficult to achieve a thin and small design.

⚗Method used

A clearance notch is formed on the support component of the lifting support mechanism, and a corner recess is formed on the keycap to accommodate the function key. Combined with the arch bridge-type support lifting design, the structural resistance to deformation is improved.

🎯Benefits of technology

Without altering the key layout, it provides space for function keys, promoting a thinner and lighter keyboard design and improving the structural stability of the base plate during assembly and disassembly.

Abstract

The utility model relates to a key and keyboard, and the key contains key cap, lifting support mechanism and bottom plate. Lifting support mechanism sets up in the key cap below and contains the first and second support piece of movablely connected key cap of cross pivot joint. The first support piece has sliding axle portion and first let -out recess. The second support piece has pivot joint axle portion and second let -out recess, and the first and second let -out recesses are collectively accommodated the corner recessed area of key cap. The bottom plate has the first and second broken hole structure respectively in the position corresponding sliding axle portion and pivot joint axle portion and is connected the first and second broken hole structure to form the first and second arch bridge structure respectively. Sliding axle portion movably presses in the first tongue piece below the first arch bridge structure and bears on the bottom plate and slides and rotates, pivot joint axle portion movably presses in the second tongue piece below the second arch bridge structure and bears on the bottom plate and rotates, so that key cap can move up and down. The utility model can solve the problem that the support design and arrangement configuration of keyboard key are limited by adding function key.
