Two-degree-of-freedom folding electric bed

Abstract

The invention discloses a two-degree-of-freedom folding electric bed. The bed comprises a first bed board and a second bed board which are respectively formed by splicing a plurality of bed boards andcan be turned over; a bed frame which is used for fixing a bed board and comprises at least a first bed frame body and a second bed frame body which are folded mutually, and a driving device used fordriving the bed board; and a connecting member which is used for connecting the first bed frame and the second bed frame in a foldable manner; the connecting member comprises a rotating member and afixing member used for fixing the rotating member. The rotating shaft movably connects the fixed part and the rotating part at the two ends of the lower edge of the rotating part, the rotating part and the fixed part can rotate relatively along the rotating shaft, the upper portion and the lower portion of the stop part form an upper stop part edge and a lower stop part edge respectively, and an arc groove is formed between the upper stop part edge and the lower stop part edge. The bed frame can be protected from being scratched in the folding process, and is easier to fold; the folding freedom degree can be limited through the stop design, and the supporting performance of the bed frame can be improved.

Description

technical field [0001] The invention relates to an electric bed, in particular to a double-degree-of-freedom folding electric bed. In particular, the invention also provides a connecting piece for connecting the folding bed. Background technique [0002] With the progress of society, more and more appliances that can facilitate people's daily life appear in large numbers. As one of the necessary appliances for people's daily life, folding beds can reduce labor intensity during transportation, and can be folded and stored to save space. At present Folding beds have been widely used in daily home, hospital care, hotels and other places for lying needs. [0003] The electric bed can electrically control the height of the head or feet of the bed board and freely adjust the bending degree of the bed board. It is divided into two categories: the skeleton type and the bed board type. . Existing electric beds are usually of integral design, that is, a large bed frame is fixedly in...

AI Technical Summary

Problems solved by technology

[0005] First, part of the double-degree-of-freedom folding design is designed with no position during the folding process and no position after unfolding, which makes it easy to scratch the frame during the folding process, and needs to add at least two bed feet in the middle to be able to use it normally. Installation More feet add to the overall weight of the bed

[0006] Second, for single-degree-of-freedom folding products, the bed foot must be installed after the whole bed is unfolded to be used normally
