The known foldable bed frame is composed of two main support frames that are pivotally connected to each other and can be folded relative to each other along the longitudinal direction of the foldable bed frame. The mattress is used to form the basic structure of the folding bed. When storing or transporting, the two mutually pivoted main support frames can be folded in half with each other, so as to facilitate storage and transport.

As far as we know, the representative patent of the folding bed with the function of folding in half is shown in Taiwan Model Announcement No. M621470 "Foldable Bed Frame Device".

In addition, as far as is known, the US patents for beds with foldable functions are as follows:

1. US2018000254 No. "Folding Bed Frame", including a folding bed frame with two symmetrically arranged bed frame units. The two bed frame units are hinged to each other at the joint. The bed frame unit is further provided with a plurality of first support rods hingedly connected with the bed frame unit. The direction in which the plurality of first support rods are folded is perpendicular to the direction in which the bed frame unit is folded.

2. US2020205576 "Light bed board and folding bed", including a bed frame and a bed board set on the bed frame. The bed frame includes a first frame unit and a second frame unit arranged side by side and pivotally connected to each other. The bed board includes a first board unit fixedly arranged on the upper side of the first frame unit and a second board unit fixedly arranged on the upper side of the second bed frame unit. Each of the first panel unit and the second panel unit includes one or more panel elements. Each panel element includes a substrate, a sponge layer and a cover. The base plate is provided on the upper side of the first or second frame unit. The sponge layer is arranged on the upper side of the base material, and the cover layer is arranged on the upper side of the sponge layer.

3. US2021337976 "Transportable Foldable Bed Frame", the bed base includes a base, the base includes a first frame with a bottom and a top, a second frame with a bottom and a top, and the second frame is pivotally connected to the first frame connector. The first frame and the second frame selectively pivot relative to each other about a pivot such that the first frame and the second frame selectively pivot relative to each other between open, unfolded positions, wherein the top of the first frame The second frame is substantially coplanar and adapted to support the mattress and in a closed folded position, wherein the bottom is folded and the top of the second frame covers the top of the first frame.

4. US2009249545 No. "Portable Folding Bed", by installing a triangular support plate at the junction between the rotating rod of the rotating support rod and the connecting rod to enhance the support strength of the rotating support rod, and a fixed plate with a fixed plate . A width twice the width of the bed frame is provided in the bed frame engaging unit of the fixed support rod, and a tighter contact unit is provided between the fixed plate and the fixed support rod, so as to obtain a stable engagement of the fixed support rod, and a central support A foldable spring is arranged between the lower cross bar of the rod and the outer frame of the bed frame, so that the folding operation can be conveniently performed in the process of folding the bed.

It can be seen from the above that although the above four US patents have the function of longitudinal folding of the bed frame; however, these US patents do not have the lateral folding function of the side wing support and the side wing bed board, so it is impossible to make the bed frame and the bed board have a horizontal folding function.
