【detailed description】

The invention will now be further described with reference to the drawings and preferred embodiments.

As shown in FIG. 1 , a rocking device 2 includes a rocking cradle and a fixed base. The cradle is two curved cradle 3 and base 4 (as shown in FIG. 2 ), the cradle 3 is a strip-shaped member having a rectangular cross section and a bow shape when viewed from the side, and a front movable magnetic member 7 and a rear movable magnetic member 5 are respectively disposed at two ends of the curved cradle 3; the base 4 may be a plate member, It may be two strips corresponding to the curved cradle 3, or a frame-shaped member assembled from a plurality of panels, or may be separately fixed separately for the magnetic members corresponding to the curved cradle 3. The fixing member at the corresponding position under the cradle 3 (ie, the cradle 3 may not be directly placed on the base, only the magnetic member on the base 4 corresponds to the position of the magnetic member on the cradle 3). As shown in FIG. 3, the base of the embodiment is formed by splicing four strip-shaped plates, wherein two long strips are used as the track 9 which is rolled when the curved cradle 3 swings, that is, the cradle 3 is placed on the track 9. At the same time, magnetic members corresponding to the cradle 3 are disposed at both ends of the track 9 at the same time: a front static magnetic member 8 and a rear static magnetic member 6, the static magnetic member and the dynamic magnetic member on the cradle 3 are opposite to the magnetic poles Or the opposite magnetic poles are opposite; the lower curved surface of the cradle 3 and the surface of the track 9 should be as smooth as possible to reduce the kinetic energy consumption of the cradle 3 as it rolls on the track 9.

Figure 3 shows a rocking chair using the above-mentioned rocking device. The leg of the chair 1 is fixed on the cradle 3, and the chair is stopped at the center of the base 4 by the position of the center of gravity of the chair, on the cradle 3 The magnetic member and the magnetic member on the base 4 are disposed opposite to each other. When the person sits on the chair 1 and leans back, the chair 1 is inclined along the outer curved surface of the curved cradle 3. When the inclination angle of the end of the cradle 3 is too large, the kinetic energy of the cradle is converted into potential energy and Mutually exclusive magnetic energy, provided at the end of the rear moving magnetic member 5 The distance of the distance is close to the increasing repulsive force of the rear static magnetic member 6 of the base 4 and the gravity of the person and the center of gravity of the chair itself. Under the force of these forces, the chair is tilted back, the potential energy and The magnetic energy is reconverted into kinetic energy; when the chair returns to the center position, the chair is still tilted forward due to the inertia, and the chair is subjected to the direct rejection of the magnetic member when the inclination angle of the end of the cradle 3 is too large. The force and the gravity of the person and the chair itself are tilted back again, and the kinetic energy loss is less. Therefore, the chair can perform multiple reciprocating swings after one force, which increases the entertainment, and because of the magnetic buffer, the comfort is better. .
