After the angle is adjusted, the mounting disc adjusting member 71 is released, and the mounting disc locking assembly 72 continues to lock the mounting disc 2. Without disassembling the automobile seat, the forward and reverse directions of the automobile seat can be adjusted, and the use is more convenient.

[0055] Further, a plurality of mounting disc adjusting grooves 22 are arranged on the mounting disc 2 in the circumferential direction. The mounting disc locking assembly 72 comprises a frame adjusting groove 721 arranged on the mounting frame 13, a mounting disc locking member 722, and a mounting disc locking spring 723 arranged between the mounting disc locking member 722 and the lower housing 12. The mounting disc locking spring 723 is used to move the mounting disc locking member 722 towards the mounting disc 2, so that the mounting disc locking member 722 locks the relative rotation position of the mounting disc 2 and the mounting frame 13 when the mounting disc locking member 722 passes through the frame adjusting groove 721 and the mounting disc adjusting groove 22 at the same time. Specifically, the mounting disc unlocking assembly 73 comprises a mounting disc unlocking inclined groove 731 arranged on the mounting disc adjusting member 71, and a mounting disc unlocking pin shaft 732 arranged on the mounting disc locking member 722. The two ends of the mounting disc unlocking pin shaft 732 are respectively inserted into the mounting disc unlocking inclined groove 731. The mounting disc unlocking inclined groove 731 cooperates with the mounting disc unlocking pin shaft 732 to push the mounting disc locking member 722 out of the mounting disc adjusting groove 22 when the mounting disc adjusting member 71 is moved in the unlocking direction.

Then, through the support of the support leg 8 at the front end, a triangular support is formed to double the anti-rollover performance and reduce the feeling of shaking, which can cope with various road conditions. The support leg 8 can be folded by swinging, which is convenient for packaging, storage and transportation.

[0057] Specifically, the support leg 8 comprises a support rod 81, a telescopic rod 82 movably arranged on the support rod 81 along the length direction of the support rod 81, and a telescopic locking mechanism 83 for locking the telescopic rod 82 to limit the movement of the telescopic rod 82 relative to the support rod 81.

[0058] More specifically, the telescopic locking mechanism 83 comprises a support rod hole 831, a support rod cover 832, a gear adjusting ring 833, a gear pin 834, a gear adjusting hole 835, and a gear locking spring 836. The support rod hole 831 is arranged on the support rod 81; the support rod cover 832 is arranged on the support rod 81; the gear adjusting ring 833 is movably arranged in the support rod cover 832 and is sleeved on the support rod 81; the gear pin 834 is arranged on the gear adjusting ring 833; the gear adjusting hole 835 is arranged on the telescopic rod 82 along the length direction of the telescopic rod 82; the gear locking spring 836 is arranged between the gear adjusting ring 833 and the support rod cover 832, and is used for pushing the gear adjusting ring 833 to keep the gear pin 834 on the gear adjusting ring 833 inserted into the support rod hole 831 and the gear adjusting hole 835. When the height of the support leg 8 needs to be adjusted, the gear adjusting ring 833 is pressed to drive the gear pin 834 away from the gear adjusting hole 835, the telescopic rod 82 is moved to the corresponding gear adjusting hole 835 relative to the telescopic rod 82 according to the height of the seat of different cars, and the gear locking spring 836 is reset to make the gear pin 834 pass through the support rod hole 831 and the corresponding gear adjusting hole 835, thereby completing the locking, which is more versatile and convenient to store.
