AI Technical Summary
Existing folding lightweight electric wheelchairs are difficult for a single person to easily assemble and disassemble, and the disassembly process is cumbersome.
A semi-automatic detachable frame is designed by setting a lever and hook structure between the front frame and the rear frame. The groove on the lever is used to lock the positioning post assembly and lift the hook. Combined with the elastic reset assembly, the front frame and the rear frame can be easily separated.
It enables convenient separation of the front and rear frames, improves separation efficiency, and solves the problem of cumbersome separation in existing technologies.
