[0025] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0026] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, this embodiment provides a seat dual-motor turntable structure, including a mounting ring seat 100, a constraint assembly 200, a rotating assembly 300 and a drive motor 400; the number of the drive motors 400 is two, and the two drive motors 400 are installed in the middle of the mounting ring seat 100; the constraint assembly 200 is fixedly arranged on the mounting ring seat 100, and a rotating mounting groove 110 is formed between the constraint assembly 200 and the mounting ring seat 100; the rotating assembly 300 includes a rotating base 310, a rotating drive disk 320 and a driving gear disk 330, the rotating base 310 is rotatably installed in the rotating mounting groove 110, the rotating drive disk 320 is fixedly installed on the rotating base 310, the driving gear disk 330 is arranged on the rotating drive disk 320, and the driving gear disk 330 is engaged with the two drive motors 400.

[0027] Specifically, the mounting ring 100 is fixedly mounted on the car body, and the car seat is mounted on the rotating assembly 300. When the user needs to rotate the car seat, the user triggers the drive motor 400 through the control button. The two drive motors 400 can simultaneously drive the drive gear disc 330 of the rotating assembly 300. The drive gear disc 330 can drive the rotating drive disc 320 to rotate synchronously. The rotating drive disc 320 can drive the rotating base 310 to rotate in the rotating mounting groove 110 between the mounting ring 100 and the constraint assembly 200. The rotating base 310 slides against the rotating mounting groove 110, and The rotating base 310, the rotating drive disk 320 and the driving sprocket 330 are stably transmitted without gap, reducing shaking. Moreover, the driving sprocket 330 is driven by two driving motors 400. During the driving process, the rotation speeds of the two driving motors 400 are adjusted to make the rotation speeds of the two driving motors 400 asynchronous, which can eliminate the gap in the rotation direction of the driving motor 400 and make the operation smoother. In addition, when locked at any position, the two driving motors 400 are reversed to make the driving gear 410 on the driving motor 400 press against the driving sprocket 330, thereby achieving zero gap in the locked state.

[0028] See also Figures 1-6 As shown, in an optional scheme of this embodiment, the constraint assembly 200 includes a constraint inner ring 210 and a constraint outer ring 220; the inner ring of the constraint inner ring 210 is fixedly mounted on the inner ring of the mounting ring seat 100, and a rotation mounting groove 110 is formed between the constraint outer ring 220 and the mounting ring seat 100; the outer ring of the constraint outer ring 220 is fixedly mounted on the outer ring of the mounting ring seat 100, and the outer ring of the rotating drive disk 320 is located between the constraint outer ring 220 and the mounting ring seat 100.

[0029] Specifically, both the constrained inner ring 210 and the constrained outer ring 220 are fixedly arranged on the mounting ring seat 100, the inner ring of the constrained inner ring 210 is fixedly installed at the inner ring of the mounting ring seat 100, and the outer ring of the constrained outer ring 220 is fixedly installed at the outer ring of the mounting ring seat 100.

In this embodiment, the range of the limiting channel 321 is such that the rotation angle limiting column 211 can rotate 180 degrees relative to the rotating drive disk 320.

[0039] In addition, limit observation windows 322 are provided at both ends of the limit channel 321 so that the staff can observe the rotation angle limit column 211 during the assembly process for assembly and alignment operations.

[0040] See also Figures 1-6 As shown, in an optional solution of this embodiment, a motor mounting plate 130 is provided at the bottom of the inner ring of the mounting ring seat 100 ; and both driving motors 400 are mounted on the motor mounting plate 130 .
