[0044] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0045] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown in

[0046] Specifically, during use, the bearing base 100 is fixedly installed on the vehicle body, the vehicle seat is installed on the bearing turntable 400, and then when the user needs to rotate the vehicle seat, the bearing turntable 400 can be rotated by a power member or manually by the user. The bearing turntable 400 drives the rotating ring 210 to rotate. The rotating ring 210 rotates between the bearing base 100 and the fixing component 300. First ball members 220 and second ball members 230 are provided between the rotating ring 210 and both the bearing base 100 and the fixing component 300. With such an arrangement, the bearing base 100, the rotating component 200, and the fixing component 300 can be combined into one body, reducing the assembly gap and thus reducing vibration and abnormal noise.

[0047] Among them, both the first ball member 220 and the second ball member 230 include a ball ring frame 241 and a plurality of balls 242. The plurality of balls 242 are evenly distributed on the ball ring frame 241. Through the arrangement of the ball ring frame 241, the positions of the plurality of balls 242 can be restricted, so as to ensure that the plurality of balls 242 are always evenly distributed on the upper and lower sides of the rotating ring 210 during the working process, thereby tightly assembling the rotating ring 210, the bearing base 100, and the fixing assembly 300 together.

[0048] See Figure 1 - Figure 6 As shown, in an alternative solution of this embodiment, a first lower ring groove 110 adapted to the first ball member 220 is formed on the bearing base 100; a second lower ring groove opposite to the first lower ring groove 110 is formed at the bottom of the rotating ring 210. The first lower ring groove 110 and the second lower ring groove cooperate to form a lower ring cavity, and the first ball member 220 is located in the first lower ring groove 110 and the lower ring cavity.

[0049] Among them, the fixing assembly 300 includes a first fixing ring 310. The first fixing ring 310 is pressed on the inner ring of the rotating ring 210, and the inner ring of the first fixing ring 310 is fixedly connected to the bearing base 100; a first upper ring groove adapted to the second ball member 230 is formed at the bottom of the first fixing ring 310; a second upper ring groove 211 opposite to the first upper ring groove is formed on the rotating ring 210. The first upper ring groove and the second upper ring groove 211 cooperate to form an upper ring cavity, and the first ball member 220 is located in the first upper ring groove and the upper ring cavity.

[0050] Among them, a first mounting seat 120 for connecting with the first fixing ring 310 is arranged on the bearing base 100.

[0051] Specifically, when the bearing turntable 400 rotates, the first ball member 220 on the lower side of the bearing turntable 400 can contact and rotate with the bearing base 100, and the second ball member 230 on the upper side of the bearing turntable 400 can contact and rotate with the first fixing ring 310, thereby ensuring the rotation stability of the bearing turntable 400, and greatly reducing the occupied space of the rotating ring 210, the bearing base 100, and the first fixing ring 310, so as to greatly improve the applicability of the seat turntable structure provided by this embodiment.

[0052] In addition, when the balls 242 are in the lower ring cavity or the upper ring cavity, the ball ring frame 241 falls on the bearing base 100 or the rotating ring 210, ensuring the even distribution of the plurality of balls 242 and the smooth rotation of the rotating ring 210.

[0053] It should be pointed out that the inner ring of the first fixed ring 310 can be fixedly connected to the supporting base 100, and the main body of the first fixed ring 310 is pressed on the rotating ring 210, thereby pressing the rotating ring 210 on the supporting base 100, reducing the space occupied after assembly, and can reduce the assembly gap, reduce the shaking gap, and is not easy to generate vibration and abnormal noise.

[0054] See also Figure 1 - Figure 6 As shown, in an optional solution of this embodiment, the fixing assembly 300 further includes a second fixing ring 320 , which is disposed on the outer ring of the rotating ring 210 ; the second fixing ring 320 is fixedly mounted on the bearing base 100 .

[0055] The outer ring edge of the rotating ring 210 is provided with a limiting flange 212 , and the inner ring of the second fixed ring 320 is provided with a limiting undercut 321 adapted to the limiting flange 212 .

[0056] Specifically, the second fixing ring 320 can limit the outer ring of the rotating ring 210 , and the second fixing ring 320 can protect the outer ring of the rotating ring 210 to prevent foreign matter from entering between the rotating ring 210 and the supporting base 100 .

[0057] See also Figure 1 - Figure 6 As shown, in an optional solution of this embodiment, a rack 410 is provided on the supporting turntable 400 , a driving motor 500 is provided on the first fixing ring 310 , and a gear 510 for matching with the rack 410 is provided at the output end of the driving motor 500 .

[0058] Specifically, the seat turntable structure provided in this embodiment can be configured to be electrically driven. A drive motor 500 is arranged on the first fixed ring 310, and a rack 410 is arranged on the supporting turntable 400. When the user needs to rotate the car seat, the start of the drive motor 500 can be controlled by a control button. The drive motor 500 drives the gear 510 to rotate, and the gear 510 transmission can drive the rack 410 to rotate, thereby driving the supporting turntable 400 to rotate.

[0059] Among them, the drive motor 500 is placed flat on the first fixing ring 310, the drive motor 500 is located inside the inner circle of the first fixing ring 310 and the supporting base 100, and the drive motor 500 is located below the supporting turntable 400, so that the setting of the drive motor 500 will not increase the thickness and volume of the seat turntable structure.

[0060] The first fixing ring 310 is provided with a second mounting seat 311 for mounting the driving motor 500 .

[0061] See also Figure 1 - Figure 6As shown in the figure, in an alternative solution of this embodiment, a plurality of angular limiting holes 213 are formed in the rotating ring 210, and a manual elastic claw 600 is arranged on the bearing base 100, and the manual elastic claw 600 can be clamped with the angular limiting holes 213.

[0062] Specifically, the seat turntable structure provided in this embodiment can be set to be manually driven. When the user needs to rotate the car seat, the user manually presses the manual elastic claw 600, so that the claw at the front end of the manual elastic claw 600 disengages from the clamping of the angular limiting hole 213, and then the user manually rotates the car seat, so that the bearing turntable 400 rotates, and then the manual elastic claw 600 is released, so that the claw at the front end of the manual elastic claw 600 is reinserted into the same or another angular limiting hole 213.

[0063] This embodiment provides a car seat, including a seat turntable structure.

[0064] Specifically, the car seat provided in this embodiment has the advantages of the above seat turntable structure compared with the prior art, which will not be elaborated here.
