The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0024] See also Figures 1 to 3 In the first aspect, the present invention provides a turntable stepless locking mechanism for eliminating gaps, comprising a rotating disk 1, a transmission member 2 and a locking assembly 3, wherein the transmission member 2 is arranged on one side of the rotating disk 1, the locking assembly 3 is arranged on one side of the rotating disk 1, and the locking assembly 3 comprises a driving rod 4, a limiting disk 5, a first rotating frame 6, a second rotating frame 7 and a locking wheel 8;

[0025] The limiting plate 5 is fixedly connected to the rotating plate 1 and is located on one side of the rotating plate 1. The driving rod 4 is arranged on one side of the limiting plate 5. The first rotating frame 6 is rotatably connected to the driving rod 4 and is located on one side of the driving rod 4. The locking wheel 8 is rotatably connected to the first rotating frame 6 and is located on the side of the first rotating frame 6 away from the driving rod 4. The second rotating frame 7 is rotatably connected to the locking wheel 8 and is rotatably connected to the rotating plate 1, and is located on the side of the locking wheel 8 away from the first rotating frame 6.

[0026] In the embodiment of the present invention, the driving rod 4 is energized to pull the first rotating frame 6, so that the first rotating frame 6 slides on the limiting plate 5 toward the middle of the rotating disk 1. At this time, the first rotating frame 6 and the second rotating frame 7 rotate themselves to increase their angle, so that the two locking wheels 8 connected thereto are separated and move away from each other, thereby unlocking the rotating disk 1; at this time, the transmission member 2 is energized to drive the rotating disk 1 to rotate, thereby adjusting the rotating disk of the car seat; the driving rod 4 is energized again to push the first rotating frame 6, so that the first rotating frame 6 slides on the limiting plate 5 toward the outside of the rotating disk 1. At this time, the first rotating frame 6 and the second rotating frame 7 rotate themselves to reduce their angle, so that the two locking wheels 8 approach each other and mesh with each other. At this time, the two locking wheels 8 are engaged with the gear ring of the rotating disk 1 The three are meshed with each other to achieve stepless locking of the rotating disk 1. The locking mechanism drives the first rotating frame 6 to rotate through the driving rod 4, so that the two locking wheels 8 connected thereto are close to each other. The second rotating frame 7 rotates to assist the movement of the locking wheel 8 to ensure that the locking wheel 8 moves smoothly. The setting of the limit plate 5 is used to limit the sliding of the first rotating frame 6 to avoid the deviation of the two locking wheels 8. The two locking wheels 8 are meshed with the gear ring on the rotating disk 1 to achieve mutual meshing of the three without a locking gap, thereby achieving complete locking of the rotating disk 1 and avoiding the phenomenon that the seat can still shake slightly after the rotating disk is locked. This solves the problem that there is a gap between the guide slider and the slide seat of the existing locking structure, and the angle of the slider and the locking gear is offset, making it impossible to completely lock the rotating disk.

[0029] Furthermore, the driving rod 4 includes a butterfly piece 11, a screw rod 12 and a rotating motor 13. The butterfly piece 11 is slidably connected to the limit plate 5 and is located on both sides of the limit plate 5.

[0030] In an embodiment of the present invention, the rotating motor 13 is energized to drive the screw rod 12 to rotate. The screw rod 12 rotates, and under the action of the thread thereon, the butterfly piece 11 slides on the screw rod 12. When the butterfly piece 11 slides, it drives the first rotating frame 6 to move together, thereby driving the two locking wheels 8 to move.

[0032] In the embodiment of the present invention, the first rotating frame 6 and the second rotating frame 7 have the same structure, and the setting of the rotating shaft 15 is used to connect the rotating rod 14 and the butterfly piece 11, so that when the butterfly piece 11 moves, the rotating shaft 15 is driven to move together. At this time, due to the movement of the rotating shaft 15, the two rotating rods 14 connected to the two locking wheels 8 rotate around the rotating shaft 15, changing the angle between the two rotating rods 14, so that the two locking wheels 8 are closer to or farther away from each other.

[0033] Furthermore, the rotating motor 13 includes a motor body 16 and a mounting plate 17, the mounting plate 17 is fixedly connected to the rotating disk 1 and is located on one side of the rotating disk 1, the motor body 16 is fixedly connected to the mounting plate 17 and is fixedly connected to the screw rod 12, and is located between the mounting plate 17 and the screw rod 12.

[0034] In the embodiment of the present invention, the mounting plate 17 is fixed to the rotating disk 1 by bolts, and the motor body 16 is used to drive the screw rod 12 to rotate, thereby driving the butterfly piece 11 to slide.

[0035] Furthermore, the butterfly piece 11 includes a butterfly piece body 18, a base plate 19 and a fixing bolt 20. The butterfly piece body 18 is threadedly connected to the screw rod 12 and is located on the outside of the screw rod 12.

[0038] S1 The driving rod 4 is energized to pull the first rotating frame 6, so that the first rotating frame 6 slides on the limiting plate 5 toward the middle of the rotating disk 1. At this time, the first rotating frame 6 and the second rotating frame 7 rotate themselves to increase their included angle, so that the two locking wheels 8 are separated and away from each other, and the rotating disk 1 is unlocked;

[0039] In the embodiment of the present invention, the rotating motor 13 is energized to drive the screw rod 12 to rotate. The screw rod 12 rotates, and under the action of the thread thereon, the butterfly piece 11 slides on the screw rod 12, driving the rotating shaft 15 to move together. At this time, due to the movement of the rotating shaft 15, the two rotating rods 14 connected to the two locking wheels 8 rotate around the rotating shaft 15, increasing the angle between the two rotating rods 14, thereby making the two locking wheels 8 move away from each other, unlocking the rotating disk 1.

[0040] The S2 transmission member 2 is energized to drive the rotating disk 1 to rotate, thereby adjusting the rotating disk of the car seat;

[0041] In the embodiment of the present invention, the output end of the driving motor 9 is powered on to rotate, driving the driving wheel 10 to rotate, thereby causing the rotating disk 1 meshed therewith to rotate, thereby realizing stepless adjustment of the car seat.

[0042] The S3 driving rod 4 is energized to push the first rotating frame 6, so that the first rotating frame 6 slides on the limiting plate 5 toward the outside of the rotating disk 1. At this time, the first rotating frame 6 and the second rotating frame 7 rotate themselves to reduce their angle, so that the two locking wheels 8 approach each other and mesh with each other. At this time, the two locking wheels 8 and the gear ring of the rotating disk 1 are meshed with each other, realizing stepless locking of the rotating disk 1.

[0043] In an embodiment of the present invention, the rotating motor 13 is energized to drive the screw rod 12 to rotate in the opposite direction. The screw rod 12 rotates in the opposite direction, and under the action of the thread thereon, the butterfly piece 11 slides on the screw rod 12, driving the rotating shaft 15 to move together. At this time, due to the movement of the rotating shaft 15, the two rotating rods 14 connected to the two locking wheels 8 rotate around the rotating shaft 15, reducing the angle between the two rotating rods 14, so that the two locking wheels 8 are close to each other, realizing the stepless locking of the rotating disk 1.
