The rotating plate connects the rotating shaft 21 of the first driving motor 2 and the bottom end of the base frame 11 with each other in parallel to the horizontal plane. The rotating piece is driven by the rotating shaft 21 to drive one end of the base frame 11 to repeatedly rise and descend, and the other end of the base frame 11 relatively repeatedly descends and rises, so that the base frame 11 integrally shakes. The rotating chassis 31 is rotatably connected with the lifting mechanism. One end of the linkage rod 14 is in a reverse hook shape and is clamped and fixed on the foot rest, and the other end of the linkage rod 14 is fixedly connected with the backrest support frame. The backrest support frame, the foot rest and the plurality of linkage rods 14 are arranged in the base frame 11. The telescopic end of the telescopic rod I15 is connected to the foot rest, and the fixed end is connected to the base frame 11. The first telescopic rod 15 contracts or extends to change the angle between the foot rest and the horizontal plane, and the plurality of linkage rods 14 drive the backrest support frame to change the same angle.
The back support frame and the foot rest are connected with each other through the plurality of linkage rods 14, so that the angle linkage change of the back support frame and the foot rest can be realized only by one telescopic rod 15, the cost of the telescopic rods is reduced, and meanwhile, the occupied space is also reduced. And the back support frame, the foot rest and the plurality of linkage rods 14 are arranged in the base frame 11, and when the first 15 compression of the telescopic rod is minimum, the back support frame, the foot rest and the plurality of linkage rods 14 are all positioned in the base frame 11, so that the space utilization rate is high, and the overall occupied position is small. The multifunctional chair not only can shake to calm children, but also can change the angle of the chair to enable the children to sit or lie, and can change the direction of the chair by rotating the chassis 31 and the lifting mechanism, and the lifting device enables the chair to adapt to tables with different heights by lifting, so that the multifunctional chair occupies small space and is low in cost while being diversified.
The invention discloses a rocking structure of a multifunctional chair. The rocking rotation mechanism includes a rotation chassis 31 and a rotation piece. The rotating plate connects the rotating shaft 21 of the first driving motor 2 and the bottom end of the base frame 11 with each other in parallel to the horizontal plane. Specifically, one end of the rotating piece is arranged on the rotating shaft 21 on one side of the first driving motor 2, and the other end of the rotating piece is connected to the bottom end of the base frame 11, which is positioned on one side of the telescopic rod 15 in the telescopic direction. The rotating piece is driven by the rotating shaft 21 to drive one end of the base frame 11 to repeatedly rise and descend, and the other end of the base frame 11 relatively repeatedly descends and rises, so that the base frame 11 integrally shakes.
As shown in fig. 3, the rotating piece includes a connecting piece 321 and an adjusting piece 322 that are connected to each other, a motor connecting hole 3211 is provided at an end of the connecting piece 321 far away from the adjusting piece 322, and a frame connecting hole 3221 is provided at an end of the adjusting piece 322 far away from the connecting piece 321. The motor connecting hole 3211 is sleeved on the rotating shaft 21 of the first driving motor 2. The inner side of the bottom end of one surface of the base frame 11 is provided with a loop bar 111, and the frame connecting hole 3221 is sleeved on the loop bar 111. The connecting piece 321 rotates under the drive of the rotating shaft 21, and simultaneously drives the adjusting piece 322 to rotate, and the adjusting piece 322 drives one end of the base frame 11 to repeatedly rise and fall through the loop bar 111, and the other end of the base frame 11 relatively repeatedly descends and rises, so that the base frame 11 integrally shakes. The linear distance between the end of the adjusting piece 322 away from the connecting piece 321 and the end of the connecting piece 321 away from the adjusting piece 322 is the shaking amplitude of the base frame 11. Changing the angle between the adjusting plate 322 and the connecting plate 321 can change the linear distance between the end of the adjusting plate 322 away from the connecting plate 321 and the end of the connecting plate 321 away from the adjusting plate 322, so as to adjust the swinging amplitude of the chair.
The rocking rotation mechanism further includes two ear plate groups rotatably provided on the rotation chassis 31, respectively, each of the ear plate groups including two ear plates 33 disposed opposite to each other.

A rotating rod 331 is arranged on one side of the ear plate 33, and the rotating rod 331 is sleeved in the adjusting hole 351 and then connected with the base frame 11. In adjusting the angle between the adjusting piece 322 and the connecting piece 321, the position of the adjusting hole 351 sleeved on the rotating rod 331 can be adjusted synchronously. The two ear plates 33 disposed opposite each other in the two ear plate groups are connected to each other by an ear plate lever 34.
