ABSTRACT:
The present invention provides a bearing mechanism with an integrated flexible bearing surface. The bearing mechanism includes a frame, which is folded to define an inner space; and an integrated flexible bearing surface, which has an elastic restoring force and is prefabricated onto the inner space of the frame. At least two sides of the integrated flexible bearing surface are mated integrally with the frame when the bearing mechanism is fabricated. The present invention enhances the structural strength, reduces greatly the fabrication cost and improves substantially the manufacturing efficiency with better applicability and industrial benefits.
