Abstract

The present disclosure provides a flexible bottom shell, where the flexible bottom shell includes a first half shell, a second half shell, and a bendable part connected the first half shell and the second half shell, where the bendable part includes a plurality of connection plates, the plurality of the connection plates are successively bonded and are successively hinged together. Hinge pieces include a fixed plate, a fixed axle, and a pin axle. The fixed axle and the pin axle are perpendicular to a surface of the fixed plate. The fixed axle is connected to the fixed plate, and the pin axle is connected to the adjacent connection plates.

First claim
