摘要： A bed frame includes: an external frame, an internal supporting portion and a bed cover. The external frame is a hollow frame. The internal supporting portion is of a large-interval structure. The internal supporting portion is arranged inside the external frame (1) to reinforce the strength of the external frame. The bed cover covers the top faces of the external frame and the internal supporting portion to form a flat bed surface.

摘要： A cradle includes a base, a support, a movable bed compartment, a wire-winding barrel, first and second wire bodies. The compartment is movably connected with the support arranged on the base in a suspended manner. First and second fixed ends are arranged on the bottom face of the compartment in the moving direction of the compartment. The barrel is located between the first and second fixed ends. The barrel is rotationally fixed to the face of the base facing to the compartment. The first and second wire bodies are respectively wound on the barrel, and the winding direction of the first wire body is opposite to that of the second wire body. The free end of the first wire body and the free end of the second wire body are respectively connected with the first fixed end and the second fixed end by means of an elastic member.

摘要： Disclosed is a foldable electric bed, which includes a head bed frame and a foot bed frame. The head bed frame has a male plate, and the foot bed frame has a female plate. The male plate and the female plate are pin-connected to each other through a pin shaft. One of the head bed frame and the foot bed frame is rotatable relative to the other one thereof by means of the pin shaft between a horizontal position and a folded position. In the folded position, the head bed frame and the foot bed frame are folded together facing each other, and both the head frame and the foot bed frame have gaps for accommodating elements that project from the bed frames.

摘要： A triple-folding electric bed includes: a first bed body (11), a second bed body (12), and a third bed body (13). The first bed body (11), the second bed body (12), and the third bed body (13) are successively in detachable fixed connection or rotatable connection at junctions; when the electric bed is spread horizontally, the first bed body (11), the second bed body (12), and the third bed body (13) are on the same level; and when the electric bed is folded, the first bed body (11), the second bed body (12), and the third bed body (13) are folded in the thickness direction. The bed body of the triple-folding electric bed is divided into three separate parts and then fully folded to reduce the length of the electric bed, which thereby reduces the packaging size of the electric bed.

摘要： A bed body structure includes a bearing mechanism, a turnover mechanism, a base and a flexible supporting layer; the turnover mechanism is arranged between the bearing mechanism and the base, and the flexible supporting layer covers the top of the bearing mechanism; the bearing mechanism includes at least two supporting assemblies; in a flat-laid state, all the supporting assemblies are horizontally arrayed on the top of the base in sequence; and in an unfolded state, the turnover mechanism enables at least one of the supporting assemblies to be upwards turned over relative to the base. According to the bed body structure, by replacing a traditional bed board with the supporting assemblies to form a supporting face, the production efficiency is improved, the cost of an electric bed is greatly reduced, the electric bed is still attractive, and it is ensured that the product quality is unchanged.
