[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] As Figures 1 to 6 shown, the present invention provides an automobile hub, including a hub body 1, and an anti-slip assembly 2 is installed on one side of the hub body 1;

[0031] The anti-slip assembly 2 includes a fixed shell 21 connected to the hub body 1. A gear ring 22 is installed in the fixed shell 21. The gear ring 22 is meshed and connected with a plurality of uniformly distributed gears 23. The gears 23 are fixedly connected with a threaded tube 24. The threaded tube 24 is threadedly connected with a movable rod 25. The movable rod 25 penetrates through the fixed shell 21. A conical head 26 is fixed at the end of the movable rod 25. The gears 23 are fixedly connected with a turning handle 27. The turning handle 27 is arranged on one side of the fixed shell 21 to control the movable rod 25 to move in the circumferential direction of the wheel, so that the conical head 26 of the movable rod 25 can be inserted into the snow or soil to enhance the friction with the ground, thereby improving the grip of the wheel, and compared with the traditional anti-slip chain, it will not cause large vibrations and noises.

[0032] Specifically, the hub body 1 includes a rim 11, spokes 12 and an axle 13. A plurality of uniformly distributed spokes 12 are fixedly arranged at equal intervals on the inner wall surface of the rim 11. The other ends of the spokes 12 are fixedly connected to the outer wall of the axle 13.

[0033] Furthermore, an annular groove for installing a tire is formed on the outer wall surface of the rim 11.

[0034] Further, the threaded tube 24 is rotatably connected to a collar 28, and the collar 28 is fixedly connected to the inner wall of the fixed housing 21 through a connecting block 29.

[0035] It should be noted that the movable rod 25 includes a threaded rod body 251. A convex groove 252 is installed on the top surface of the threaded rod body 251. A movable block 253 is provided in the convex groove 252. A spring 254 is connected to the bottom of the movable block 253. The top of the movable block 253 is fixedly connected to a telescopic rod body 255. The conical head 26 is fixed to the end of the telescopic rod body 255, enabling the conical head 26 to be telescopic. Relying on the elastic force of the spring 254, the conical head 26 is inserted into the snow or soil, and it is not easy to cause great damage to the road surface, which is beneficial for use.

[0036] It should be noted that a through hole 210 is opened at the position on the fixed housing 21 corresponding to the threaded rod body 251. A positioning sliding groove 211 is opened on the outer wall of the threaded rod body 251. A positioning sliding block 212 is provided in the positioning sliding groove 211, and the positioning sliding block 212 is arranged on the inner wall of the through hole 210. By relying on the positioning sliding groove 211 and the positioning sliding block 212 to limit the rotation of the movable rod 25, the movable rod 25 can be moved under the action of the thread.

[0037] It is worth introducing that a locking bolt 213 is provided on the rotary handle 27, and a locking screw hole 214 is opened at the position on the fixed housing 21 corresponding to the locking bolt 213, which is used to fix the rotary handle 27 to prevent the rotation of structures such as the gear ring 22, the gear 23, and the threaded tube 24 due to vibration or other factors.

[0038] It should be emphasized that evenly distributed fixing ears 3 are fixed on the outside of the fixed housing 21. Fixing bolts 4 are provided on the fixing ears 3. Fixing screw holes 5 are opened at the positions on the hub body 1 corresponding to the fixing bolts 4, and the fixing screw holes 5 are threadedly connected to the fixing bolts 4, which are used to connect the fixed housing 21 and the hub body 1.

[0039] Working principle and process: The anti-slip assembly 2 is fixed to one side of the hub body 1 by fixing bolts 4. Under normal conditions, most of the movable rod 25 of the anti-slip assembly 2 is retracted into the threaded tube 24 and will not affect the wheel. When driving on snow or muddy ground, rotate the rotary handle 27, and then the gear ring 22 drives the gear 23 to rotate, and then the threaded tube 24 rotates. Under the action of the thread and the positioning sliding groove 211 and the positioning sliding block 212, the movable rod 25 moves until the conical head 26 can contact the ground when the wheel rotates. The conical head 26 will be inserted into the snow and soil, which can improve the grip of the wheel and is not easy to slip. And compared with traditional anti-slip chains, it will not cause great noise and vibration. The structure of the movable rod 25 causes the conical head 26 to contract when touching the road surface to avoid damage to the road surface by the conical head 26, which is beneficial for the use of automobile wheels.
