Description

TECHNICAL FIELD

[0001] The utility model relates to electric bed technical field, concretely relates to an improved swing electric bed. BACKGROUND

[0002] At present, the types of electric beds are more various, and the parts of the conventional electric bed frame are in a relatively fixed state, in order to improve the comfort and better help the human body to sleep, the electric bed needs to be improved, especially the bed frame is optimized and designed, so that the bed frame can swing within a certain range, most of the existing swingable electric beds rely on manual operation, which greatly reduces the comfort. In addition, although there are swing electric beds at present, the structure is not reasonable, the support point position is set at the center of the bed, and the position of the person on the bed is not fixed. When a person sleeps, he or she will also turn over and move. When the center of gravity of the human body deviates from the center of the bed, the load of the motor and the operation of the machine will change (deviate), thereby generating noise and friction sound of the motor and the machine part.

[0003] As Figure 1 shown, the support point P1 of the prior art is set in the middle of the base frame 20, and the other two hinge points P2, P3 are connected with the middle of the bed head and the bed tail respectively, the support point P1, the hinge point P2 and the hinge point P3 are almost on the central axis L of the bed body, forming a triangular support structure, when a person P4 sits in one corner of the bed head or one corner of the bed tail, the triangular support structure is unbalanced, resulting in the bed body being inclined by the person; and the triangular support structure is subjected to horizontal component force, which is easy to cause damage to the connecting part and shorten the service life. Furthermore, as the size of the bed increases (for example, a large bed with a size of 1.9*2 meters), when the person P4 sits in one corner of the bed head or one corner of the bed tail, the force arm of the distance from the person's gravity to the middle of the bed will also increase, resulting in more unbalanced force of the triangular support structure and more obvious inclination.
