[0022] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention.

[0023] See Figures 1 to 4 This embodiment provides a rocking device for a rocking chair, comprising a rocking chair body 12, a rocking drive assembly 2, and a controller. The rocking drive assembly 2 comprises a first mounting base 3, a first drive motor 4, a gear set, and a connecting rod 7. The gear set comprises a master gear 5 and slave gears 6, with two slave gears 6 symmetrically mounted on either side of the master gear 5 and meshing with each other. The first drive motor 4 is fixed to the first mounting base 3, with its shaft fixedly connected to the axle of the master gear 5 via the first mounting base 3. The two slave gears 6 are rotationally connected to the first mounting base 3. The radius of the master gear 5 is smaller than that of the slave gears 6, and the two slave gears 6 are of the same size and radius. Specifically, in some embodiments, a rotating shaft 8 is fixed to the first mounting base 3. A bearing 22 is fixed at the center of the slave gears 6 and is fixedly connected to the rotating shaft 8. The bearing 22 assists the gear rotation, reducing friction and noise. The bottom end of the connecting rod 7 is fixedly mounted to the wheel center of the slave gear 6, and the top end is hinged to the rocking chair body 12.

[0024] like Figure 1 and Figure 2The controller is electrically connected to the first drive motor 4. When the controller drives the first drive motor 4 forward and reverse, the master gear 5 rotates forward and reverse, causing the meshing slave gear 6 to rotate accordingly. A connecting rod 7 fixed to the slave gear 6 drives the rocking chair body 12 to rock left and right within a set rocking angle. The overall rocking structure is simple, with fewer interconnected moving parts, making it easy to install, maintain, and replace.

[0025] In some embodiments, as Figure 2 The rocking chair body 12 includes an upper connecting portion 9 and a lower connecting portion 10. The upper and lower connecting portions 9 and 10 are detachably connected, and their detachable connection structure can adopt existing detachable structures. A connecting piece 11 extends downward from the lower connecting portion 10, which is hingedly connected to the top of the connecting rod 7. Separating the rocking chair body 12 into the upper and lower connecting portions 9 and 10 facilitates replacement and maintenance.

[0026] In some embodiments, in order to ensure that the controller controls the rocking chair body 12 to rock within the set rocking angle, an infrared detection device is also installed. The infrared detection device includes a sensor and a sensor receiver, and the controller and the sensor receiver are electrically connected. The infrared detection device is a prior art and is set accordingly according to the rotation angle requirement. The sensor receiver is fixed on the first mounting seat 3, and the sensor is fixed on the rocking chair body 12 according to the required rocking angle requirement. When the controller controls the first drive motor 4 to rotate forward or reverse, when the rocking chair body 12 drives the sensor to swing left or right, when the sensor receiver senses it, the controller receives the sensing signal and adjusts the direction of the first drive motor 4, thereby controlling the swing range of the rocking chair body 12.

[0027] like Figure 2 and Figure 3 In some embodiments, the first mounting base 3 includes an integrally formed base plate 12 and a connecting plate 13. Two connecting plates 13 are fixedly mounted perpendicularly to the base plate 12 at intervals. The first drive motor 4 is fixedly mounted between the two connecting plates 13. The shaft of the first drive motor 4 passes through the connecting plates 13 and is fixedly connected to the main gear 5. The rotating shaft 8 is fixed to the connecting plates 13, and the end of the rotating shaft 8 is fixedly connected to the bearing 22 on the slave gear 6.

[0028] Two gear sets are mounted on the first mounting base 3, symmetrically mounted on the outsides of the two connecting plates 13. The shaft 8 is fixed to the two connecting plates 13, and the ends of the shaft 8 are fixedly connected to the bearings 22 of the two slave gears 6 symmetrically arranged on the two connecting plates 13. The two gear sets interact with the rocking chair body 12, ensuring relative stability and safety during rocking.

[0029] As shown Figure 1 、 Figure 2 and Figure 4The rocking device of the rocking chair in this embodiment also includes a horizontal drive assembly 14. The horizontal drive assembly 14 includes a second mounting seat 15, a second drive motor 16, a main pulley 17 and a slave pulley 18. The second motor is fixedly mounted on the second mounting seat 15, and the shaft of the second drive motor 16 is also fixedly connected to the shaft of the main pulley 17, driving the main pulley 17 to rotate. The second slave pulley 18 is also mounted on the second mounting seat 15, and its main pulley 17 and the slave pulley 18 are driven by a belt. An eccentric shaft 23 is provided on the slave belt, and the eccentric shaft 23 is fixedly connected to the first mounting seat 3 (the eccentric shaft 23 as a whole can also be set as shown in FIG. Figure 4 The controller controls the second drive motor 16 to drive the main pulley 17 to rotate, and the belt drives the slave pulley 18 to rotate, so that the first mounting seat 3 and the rocking chair body 12 perform horizontal circular motion under the rotation of the deflection axis.

[0030] Furthermore, in some embodiments, the second mounting base 15 is further provided with a plurality of auxiliary rotating members 19 to assist the first mounting base 3 in performing horizontal circular motion, thereby ensuring the stability and safety of the horizontal motion of the first mounting base 3 and the rocking chair body 12. The auxiliary rotating members 19 include a crank 20 and a bearing 22 seat 21. The bearing 22 seat 21 is fixed to the second mounting base 15. One end of the crank 20 is fixedly connected to the bearing 22 of the bearing 22 seat 21, and the other end is fixedly connected to the first mounting base 3. The plurality of auxiliary rotating members 19 are disposed around the outer periphery of the slave pulley 18.
