[0040] In a specific embodiment of this utility model, the rotating shaft 15 drives the winding wheel 10 to rotate, and the rotating winding wheel 10 can wind up the binding strap 8. The conveying shaft 7 is set to assist the binding strap 8 in winding up, thereby reducing the friction between the binding strap 8 and the limiting frame 1, thereby improving the service life of the binding strap 8.

[0041] Specifically, the binding component is located on the winding component. The binding component includes a binding strap 8 and a hook A9. The binding strap 8 is fixedly connected to the winding wheel 10 and is wound around the winding wheel 10. The hook A9 is fixedly connected to one end of the binding strap 8.

[0042] In a specific embodiment of this utility model, the hook A9 is used to hang on the car carrier, and the strap 8 is used to tie the tires.

[0043] Specifically, the drive component is mounted on the limiting frame 1 and connected to the mounting shaft 15. The drive component includes a mounting shell 2, a worm gear 3, a forward / reverse motor 5, a worm wheel 11, and limiting rings 16. There are two limiting rings 16, both of which are fixedly connected to the circumferential surface of the mounting shaft 15. The worm wheel 11 is movably sleeved on the mounting shaft 15 and is located between the two limiting rings 16. The mounting shell 2 is fixedly connected to one side of the limiting frame 1. The worm gear 3 is rotatably connected to the side wall of the mounting shell 2, and one end of the worm gear 3 rotatably passes through the mounting shell 2 and extends to the outside of the mounting shell 2. The worm gear 3 and the worm wheel 11 mesh with each other. The forward / reverse motor 5 is fixedly connected to the limiting frame 1, and the output end of the forward / reverse motor 5 is fixedly connected to the worm gear 3.

[0044] In a specific embodiment of this utility model, the output end of the forward and reverse motor 5 drives the worm gear 3 to rotate, and the rotation of the worm gear 3 drives the worm wheel 11 to rotate.

[0045] Specifically, the connecting component is located on the mounting shaft 15 and is connected to the driving component. The connecting component includes a U-shaped plug 4, a connecting ring 12, a plug-in ring 13, a spring 17, and a plug hole 18. Multiple plug holes 18 are provided, and all of the multiple plug holes 18 are opened on the worm gear 11. Both ends of the U-shaped plug 4 are sequentially and movably inserted into the mounting shell 2, the limiting ring 16, and the worm gear 11, and both ends of the U-shaped plug 4 are respectively movably inserted into two plug holes 18. The plug-in ring 13 is fixedly connected to the mounting shaft 15 and is movably sleeved on the U-shaped plug 4.

The connecting ring 12 and the spring 17 are used to limit the movement of the U-shaped plug 4. The movement of the U-shaped plug 4 can drive the movement of the connecting ring 12. The movement of the connecting ring 12 can compress the spring 17. The U-shaped plug 4 is removed from the worm wheel 11, so that the rotation of the worm wheel 11 will not drive the rotation of the mounting shaft 15.

[0047] Specifically, the limit frame 1 is fixedly connected with an anti-slip pad 6.

[0048] In a specific embodiment of this utility model, the anti-slip pad 6 is designed to fit against the tire, thereby increasing friction.

[0049] The working principle or process of the automatic car carrier tie-down device provided by this utility model is as follows: The hook A9 is hung on the car carrier, and the tie-down strap 8 is simultaneously placed on the tire. The forward and reverse motor 5 is driven, and the output end of the forward and reverse motor 5 rotates, causing the worm gear 3 to rotate. The worm gear 3 rotates, causing the worm wheel 11 to rotate. Since the U-shaped insert 4 is movably inserted into the limiting ring 16 and the worm wheel 11, the limiting ring 16 rotates, causing the worm wheel 11 to rotate. The worm wheel 11 rotates, causing the mounting shaft 15 to rotate. The mounting shaft 15 rotates, causing the winding wheel 10 to rotate. The winding wheel 10 rotates and winds up the tie-down strap 8, simultaneously securing the tie-down strap 8 tightly to the tire. Pulling the U-shaped insert 4 causes the connecting ring 12 to move, compressing the spring 17. The U-shaped insert 4 moves away from the worm wheel 11, allowing the winding wheel 10 to rotate freely, thus loosening the tie-down strap 8.

[0050] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
