The electric bed frame is a product that can improve the comfort of the user. It is usually driven by one or more motors and can be bent and folded at different angles according to a predetermined trajectory, so that it can provide users with lying, semi-lying , Support between sitting positions.

Currently, electric bed frames are divided into two types, one is a non-foldable type, and the other is a foldable type. For the non-foldable electric bed frame, since its layout and structure are not limited, the cost is low, but there are problems that it is not easy to pack, store, carry or transport. Another type of foldable electric bed frame has higher requirements on layout and structure, so as to further realize the functions of easy packaging, storage, carrying or transportation while ensuring its inherent functions. However, there are still some problems with the current foldable electric bed frame:

1. The overall structure is not compact enough, especially the transmission parts are redundant, resulting in an excessively high height in the folded state, which is not conducive to packaging, transportation and storage during subsequent use.

2. In the process of packaging and transportation, a large amount of foam or sponge needs to be temporarily placed between the folded bed frames to prevent the bed frames from colliding with each other; and in the later use, it is necessary to arrange a soft covering around the bed frames to prevent them from colliding with each other. It plays a protective role; thus, there is a waste of materials and a waste of manpower in the packaging process.

3. It is inconvenient to install or disassemble between the foot of the bed and the bed frame, so that the bed frame cannot be in smooth and even contact with the ground during subsequent use, and the bed frame is likely to be twisted and produce abnormal noise after long-term use.
