[0016] The rotation and locking structure of the automobile seat of the present invention will be further described in detail below through specific embodiments.

[0017] like Figures 1 to 4 As shown, the rotation and locking structure of the car seat includes a fixed seat 1 fixed on the bottom plate of the car, a fixed plate 2 is fixed on the fixed seat 1, the inner ring of the fixed plate 2 is provided with teeth 3, two limiting holes 4 are provided on the fixed plate 2, and the two limiting holes 4 are 180 degrees apart in the circumferential direction of the fixed plate 2, a rotating plate 5 is movably provided on the fixed plate 2, and the rotating plate 5 can rotate on the fixed plate 2, and a rotating motor 6 and a locking motor 7 are provided on the rotating plate 5, and the rotating motor 6 is connected to the rotating plate 5 through a first bracket 8. The locking motor 7 is connected to the rotating plate 5 through a second bracket 9. A rotating gear 10 is provided on the output shaft of the rotating motor 6, and the rotating gear 10 is meshed with the teeth 3 in the fixed plate 2, and a locking pin 11 is provided on the output shaft of the locking motor 7, and the locking pin 11 is matched with the limiting hole 4 on the fixed plate 2.

[0018] When the output shaft of the locking motor 7 is extended, there is an elastic connection between the locking pin 11 and the output shaft. When the locking motor 7 is powered on in the forward direction, its output shaft will drive the locking pin 11 to retract, and the turntable is unlocked. When the locking motor 7 is powered on in the reverse direction, the locking pin 11 is always in the extended state, and the locking pin 11 is extended by the force of the spring and is elastic. When the rotating disk 5 rotates, the locking pin 11 is in the extended state and slides into the limit hole 4 along the fixed disk 2 through line contact.

[0019] The movable connection structure between the fixed disk 2 and the rotating disk 5 is as follows: a circumferential groove 12 is provided in the outer side surface of the fixed disk 2, and the inner ring of the rotating disk 5 is movably clamped in the groove 12. A lubricating block 13 is provided in the groove 12. The provision of the lubricating block 13 not only ensures the smoothness of the rotating disk 5 during rotation, but also avoids abnormal noise during rotation.

[0020] The working principle of the utility model is as follows: when in use, the car seat is set on the rotating disk 5, the rotating motor 6 on the rotating disk 5 is running, and the rotating disk 5 drives the car seat to rotate 180 degrees through the meshing relationship between the rotating gear 10 and the teeth 3 on the fixed disk 2, and then the locking pin 11 is inserted into the limiting hole 4 to achieve locking, thereby achieving 180-degree reliable rotation and locking of the car seat. When unlocking, it is only necessary to energize the output shaft of the locking motor 7 in the forward direction, and the output shaft will drive the locking pin 11 to retract to achieve unlocking.

[0021] The above-mentioned embodiments are only illustrative of the principles and effects of the invention, as well as some embodiments of its application, and are not intended to limit the invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the invention, and all of these belong to the protection scope of the invention.
