[0024] An electric rocking chair structure includes a base 1, a seat body 2, and a driving device 3 arranged on the base 1 and used to drive the seat body 2 to rock relative to the base 1. A universal connecting seat 4 is provided between the seat body 2 and the base 1. A rotating shaft 30 is provided on the output end of the driving device 3. The two ends of the rotating shaft 30 are respectively provided with a first eccentric shaft 301 and a second eccentric shaft 302. The first eccentric shaft 301 and the second eccentric shaft 302 are respectively hinged with a first linkage rod 303 and a second linkage rod 304. The first linkage rod 303 and the second linkage rod 304 are hinged to the bottom of the seat body 2.

[0025] To enable the seat body 2 to perform a reciprocating tilting and rocking motion within a 360° range, a first connecting protrusion 307 and a second connecting protrusion 308 are respectively provided at each end of the rotating shaft 30. A first eccentric shaft 301 and a second eccentric shaft 302 are respectively disposed at the ends of the first and second connecting protrusions 307, 308. The central axes of the first and second connecting protrusions 307, 308 form an angle greater than 0° and less than 180°. During rocking, the seat body 2 rocked in all directions, front, back, left, and right, and these rocking motions superimposed on each other, forming a reciprocating rocking motion within a 360° range.

[0026] In order to make the force on the seat body 2 more balanced and the amplitude of the shaking more uniform when shaking, the angle is equal to 90°, and the first eccentric shaft 301 and the second eccentric shaft 302 are respectively arranged at the lower ends of the first connecting protrusion 307 and the second connecting protrusion 308.

[0027] like Figure 6As shown, the universal connecting seat 4 includes a lower connecting seat 41 fixedly connected to the base 1 , an upper connecting seat 42 fixedly connected to the bottom of the seat body 2 , and a universal connecting head 43 hinged between the lower connecting seat 41 and the upper connecting seat 42 .

[0028] To ensure sufficient freedom and improve the stability of the rocking of the seat body 2, a first ball joint 305 is provided between the first linkage rod 303 and the second linkage rod 304 and the end of the rotating shaft 30, and a second ball joint 306 is provided between the first linkage rod 303 and the second linkage rod 304 and the bottom of the seat body 2.

[0029] To ensure sufficient power, the drive device 3 includes a drive motor 31 and a worm gear mechanism 32 disposed between the output end of the drive motor 31 and the rotating shaft 30. The base 1 is provided with a connecting cover 10 that covers the drive device 3. A first linkage rod 303 and a second linkage rod 304 extend upward from either side of the connecting cover 10 and are hingedly connected to the bottom of the seat body 2. The lower connecting base 41 is fixedly connected to the top of the connecting cover 10.

[0030] To facilitate transportation, the bottom of the base 1 is provided with a pulley 101 and a support leg 102 for support and adjustable height. When it is necessary to transport the electric rocking chair, the support leg 102 is adjusted upward (the height of the support leg 102 is adjusted by adjusting the nut 103) so that the pulley 101 is directly in contact with the ground. At this time, the electric rocking chair can be easily moved to the designated location. When it is necessary to use it normally, the support leg 102 is adjusted downward so that the support leg 102 is directly in contact with the ground and the pulley 101 is propped up (the pulley 101 is now off the ground), thereby activating the support function and ensuring stability during use.

[0031] In order to facilitate players to step on the pedals and further improve the comfort of play, a foot pedal 5 is rotatably provided on the front side of the base 1. The bottom of the foot pedal 5 is also provided with a pulley 101 and a support foot 102 for support and adjustable height.

[0032] In order to accurately control the number of times each shaking occurs, the driving device 3 is provided with a counter 33 for controlling the driving motor 31 to stop working, and the rotating shaft 30 is provided with a counting block for triggering the counter 33 to count.

[0033] In order to allow the player to independently select the appropriate shaking speed according to actual needs, the foot pedal 5 is provided with a foot throttle 51 electrically connected to the driving device 3 to control its movement speed.

[0034] In order to ensure the overall aesthetics, a shielding device 6 is provided between the seat body 2 and the base 1 .

[0035] When the present invention is in use, the drive motor 31 drives the rotating shaft 30 to rotate through the worm gear mechanism 32. The rotation of the rotating shaft 30 drives the first linkage rod 303 and the second linkage rod 304 to swing back and forth relative to the rotating shaft 30, thereby driving the seat body 2 to rock back and forth relative to the base 1 (the seat body 2 rocks with the universal joint 43 as the rocking center). Players can experience the rocking fun of the seat body 2 while sitting on the seat body 2. The present invention is compact in size, occupies little space, and is suitable for home use.
