Problems solved by technology

[0002] Generally, beds, chairs or sofas are mostly fixed, and a few chairs or sofas have the function of swinging in one direction. For example, although a rocking chair can rock, it can only swing in the front and rear directions. After a long time of use, it will make people feel monotonous and tired. , and when the chair tilts too much when shaking, it is easy to make people feel uneasy, causing users to be unable to fully relax

Abstract

The utility model discloses a base for a bed, a chair or a sofa. The base comprises a fixed frame, a first cradle, a first driving device, a second cradle and a second driving device, the first cradle is arranged on the fixing frame through the four cantilevers; the top ends and the bottom ends of the four cantilevers are pivoted to the fixing frame and the first cradle respectively; the distance between the top ends of the two cantilevers in pair is smaller than the distance between the bottom ends of the two cantilevers in pair; the first driving device can drive the first cradle to swing left and right relative to the fixing frame and change the inclination angle at the same time; and the swing track is in a circular arc shape with an upward opening shown in the specification; the second cradle is arranged on the first cradle through four cantilevers, the top ends and the bottom ends of the four cantilevers are pivoted to the first cradle and the second cradle respectively, the distance between the top ends of the two cantilevers in pair is smaller than that between the bottom ends of the two cantilevers in pair, the second driving device can drive the second cradle to swing back and forth relative to the first cradle and change the inclination angle at the same time, and the swing track is also arc-shaped with an upward opening. Therefore, the two driving devices can adjust the speed of the motor, so that the base has a universal swinging function, and the inclination angle change in the swinging process is moderate.

Description
