[0026] Please see Figures 1 to 5 This utility model provides a technical solution: an electric rotating device for a car seat, including a lower plate 2 fixed on a car seat guide rail, an upper plate 1 fixed on a car seat frame assembly, a motor, and a planetary gear assembly; a steel ball upper retainer 3, a plastic upper retainer 4, an upper intermediate plate 5, a plastic lower retainer 6, a steel ball lower retainer 7, and an lower intermediate support plate 8 are provided between the upper plate 1 and the lower plate 2; a lower groove 13 is formed on the lower surface of the plastic upper retainer 4, and a lower ball bearing 12 is provided in the lower groove 13; an upper groove 1 is formed on the upper surface of the plastic lower retainer 6. 5. The upper groove 15 is provided with an upper ball bearing 14. The upper steel ball retainer 3, the upper plastic retainer 4, the lower plastic retainer 6, the lower steel ball retainer 7 and the lower plate 2 are fixedly connected by bolts. The upper plate 1 and the upper plate of the intermediate frame 5 are fixedly connected by bolts. The planetary gear assembly includes an outer wheel 9, a planetary connecting wheel 10 and an inner wheel 11. The inner wheel 11 is connected to the upper plate 1 by bolts. The planetary connecting wheel 10 is rotatably connected to the upper plate 1. The outer wheel 9 is matched and meshed with the planetary connecting wheel 10. The planetary connecting wheel 10 is matched and meshed with the inner wheel 11. The inner wheel 11 is connected to the motor drive end.

[0027] Furthermore, the outer wheel 9 is fixedly connected to the lower plate 2, and the inner wheel 11 is rotatably connected to the upper plate 1.

[0028] In this embodiment, the device includes a lower plate 2 fixed to the car seat guide rail and an upper plate 1 fixed to the car seat frame assembly, a motor that drives the device to rotate, and a planetary gear assembly. Between the upper plate 1 and the lower plate 2 are provided an upper steel ball retainer 3, an upper plastic retainer 4, an upper intermediate support plate 5, a lower plastic retainer 6, a lower steel ball retainer 7, and a lower intermediate support plate 8. The planetary gear assembly includes an outer wheel 9, a planetary connecting wheel 10, and an inner wheel 11. A lower groove 13 is formed on the lower surface of the upper plastic retainer 4, and a lower ball bearing 12 is disposed within the lower groove 13. An upper groove 15 is formed on the upper surface of the lower plastic retainer 6, and an upper ball bearing 14 is disposed within the upper groove 15. The upper retainer 3, plastic upper retainer 4, plastic lower retainer 6, steel ball lower retainer 7, and lower plate 2 are fixedly connected by bolts passing through five part through holes. The upper plate 1 and the upper plate 5 of the intermediate support are fixedly connected by bolts passing through two part through holes. The outer wheel 9 is fixedly connected to the lower plate 2, the planetary connecting wheel 10 is rotatably connected to the upper plate 1, and the planetary connecting wheel 10 is matched and meshed with the outer wheel 9. The inner wheel 11 is rotatably connected to the upper plate 1, and the inner wheel 11 is matched and meshed with the planetary connecting wheel 10. Through the above methods, this device can make the car seat rotate flexibly, with small gaps in movement, no noise during rotation, strong versatility, good stability, and compact structure, fully meeting the needs of customers.

[0029] In the planetary gear assembly, the planetary connecting wheel 10 balances the rotational clearance to a certain extent, so that when the planetary gear assembly rotates, the clearance of the three gears (outer gear 9, planetary connecting wheel 10 and inner gear 11) will not be too large, or the teeth will be too tightly meshed and generate noise, thus achieving noiseless rotation;

[0030] When steel balls roll on the track, the track provides insufficient constraint to each steel ball, giving them a certain degree of freedom. This results in deviations in the rolling trajectory, a phenomenon known as poor consistency in high-ball rolling. In this device, the upper plate 5 of the intermediate support includes an inner ring 51 and a bent portion 52. The bent portion 52 is located between the side walls of the upper plastic retainer 4 and the lower plastic retainer 6, while the inner ring 51 is located between the lower ball 12 and the upper ball 14. This reduces the rolling gap, minimizing abnormal noises and inconsistencies that occur when the lower ball 12 and the upper ball 14 roll. The upper plate 5 of the intermediate support can rotate flexibly with minimal movement gaps.

[0031] The planetary connecting wheel 10 is located between the inner wheel 11 driven by the motor and the outer wheel 9, which reduces the rotational clearance, that is, reduces the rotational clearance between the outer wheel 9, the planetary connecting wheel 10 and the inner wheel 11.

[0032] Both the upper plastic retainer 4 and the lower plastic retainer 6 are made of nylon, which has high strength, good wear resistance, and good durability.

[0033] This electric rotating car seat device comprises an upper plate 1, a lower plate 2, a motor, and a planetary gear assembly. The planetary gear assembly includes an outer wheel 9, a planetary connecting wheel 10, and an inner wheel 11. The motor drives the inner wheel 11 to rotate, and the inner wheel 11 is fixedly connected to the upper plate 1. The inner wheel 11 drives the planetary connecting wheel 10 to rotate, and the planetary connecting wheel 10 drives the outer wheel 9 to rotate. The outer wheel 9 is fixedly connected to the lower plate 2, thereby generating relative rotation between the upper plate 1 and the lower plate 2. This allows the car seat to rotate flexibly with minimal clearance, noiseless rotation, strong versatility, good stability, and a compact structure, fully meeting customer needs.

[0034] Furthermore, both the upper plastic retainer 4 and the lower plastic retainer 6 are made of nylon.

[0035] In this embodiment, both the upper plastic retainer 4 and the lower plastic retainer 6 are nylon retainers, which have high strength, good wear resistance, and good durability.

[0036] For further details, please refer to Figure 5 The upper plate 5 of the intermediate frame includes an inner ring portion 51 and a bending portion 52, which is disposed between the side wall of the upper plastic retainer 4 and the side wall of the lower plastic retainer 6.

[0037] For further details, please refer to Figure 5 The inner ring 51 is located between the lower ball 12 and the upper ball 14.

[0038] In this embodiment, the upper plate 5 of the intermediate support includes an inner ring portion 51 and a bending portion 52. The bending portion 52 is disposed between the side wall of the upper plastic retainer 4 and the side wall of the lower plastic retainer 6. The inner ring portion 51 is disposed between the lower ball 12 and the upper ball 14, which reduces the rolling gap and reduces the abnormal noise and inconsistency that occur when the lower ball 12 and the upper ball 14 roll. The upper plate 5 of the intermediate support can rotate flexibly and has a small slip gap.

[0039] The working principle and usage of this utility model: This electric rotating car seat device includes an upper plate 1, a lower plate 2, a motor, and a planetary gear assembly. The planetary gear assembly includes an outer wheel 9, a planetary connecting wheel 10, and an inner wheel 11.
