AI Technical Summary

Technical Problem

The large packaging volume of existing smart electric beds makes transportation and assembly inconvenient, especially the excessively thick packaging of folding beds, which affects transportation efficiency.

Method used

The bed frame adopts a staggered folding hinge structure. Through the staggered overlapping design of the front and rear lower frames, combined with the bending treatment of the first side tube, the bed frame can be folded at a low height to avoid interference.

Benefits of technology

This effectively reduces the folding height of the bed frame, simplifies the transportation and assembly process, and reduces packaging volume.

Abstract

本实用新型公开了一种错位折叠铰链结构，包括前下框和后下框，所述前下框和后下框之间通过铰链组件转动连接；所述前下框的两侧分别设置有第一侧边管，所述第一侧边管包括依次连接的第一水平段、倾斜段和第二水平段；所述后下框的两侧分别设置有第二侧边管；两个第二侧边管之间的间距大于两个第一侧边管之间的间距。本实用新型当需要折叠时，将后下框通过链组件翻折至前下框一侧，由于前下框两侧的第二侧边管之间的间距大于前下框两个第一侧边管之间的间距，因此前下框和后下框会错位重叠，第一侧边管和第二侧边管不会有干涉；同时第一侧边管做了打弯处理，从而保证后下框的横向管件不会与其干涉，最终实现床架折叠的同时降低了折叠高度。
