AI Technical Summary
The existing electric bed frame structure is unreasonable, leading to technical problems in terms of human comfort and mechanical components: In the existing technology, the various parts of the electric bed frame are in a relatively fixed state, resulting in a short lifespan for both comfort and mechanical components. Furthermore, the relatively fixed state of the various parts of the existing electric bed frame significantly reduces comfort, and the unreasonable position of the support points leads to uneven stress on the bed, causing tilting and noise.
The design of the balanced rocking electric bed uses rocking components and balance bars on both sides of the bottom of the bed frame. The drive component drives the bed frame to rock, and the balance bars evenly distribute the force on the bed body, thus overcoming the problem of uneven force distribution.
This design achieves even force distribution on the bed, preventing bed tilting and noise generation, and improving service life and comfort.

TECHNICAL FIELD
[0001] The utility model relates to electric bed technical field, concretely relates to a balanced type 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 mechanism will change (deviate), thereby generating noise and friction sound of the motor and the mechanical 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 points P2, 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, causing the bed body to be inclined by the person; and the triangular support structure is subjected to horizontal component force, which is easy to cause damage to the connection part and shorten the service life. Moreover, as the size of the bed increases (for example, a large bed with a size of 1.9*2 meters), when a 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, causing the triangular support structure to be more unbalanced and the inclination to be more obvious.
