[0003] The belt of the existing in-wheel motor is generally directly sleeved on the outer wall of the wheel hub, and only the side parts of the wheel hub and the belt are in contact. After being used for a long time, slippage will occur between the wheel hub and the belt, affecting the service life of the in-wheel motor. Content of the Utility Model:

[0004] The purpose of the utility model is to provide a covering type anti-slip wheel hub with simple structure, convenient installation, not easy to slip, and good shock absorption effect.

[0005] The utility model is realized by the following technical solutions:

[0006] A covering type anti-slip wheel hub includes a wheel hub body. A plurality of anti-slip blocks are evenly distributed along the circumferential direction of the outer wall of the wheel hub body. The outer walls of the anti-slip blocks are on the same circumference, and anti-slip grooves are evenly formed on the outer walls of the anti-slip blocks and recess inward. The two side end faces of the anti-slip blocks are flush with the two side end faces of the wheel hub body. A groove that recesses inward is formed between two adjacent anti-slip blocks, and both sides of the groove penetrate through the two side end faces of the wheel hub body.

[0007] In order to further improve the anti-slip effect, in a preferred embodiment of the utility model, two circles of anti-slip blocks are evenly distributed along the circumferential direction of the outer wall of the wheel hub body, and one circle of anti-slip blocks is staggeredly distributed on one side of the groove between the other circle of anti-slip blocks.

[0008] Furthermore, an annular groove that recesses inward is formed between the two circles of anti-slip blocks.

[0009] Furthermore, the connection between the anti-slip block and the groove adopts an arc transition.

[0010] Furthermore, the side width of the anti-slip block is greater than the side width of the groove.

[0011] In order to facilitate the processing and assembly molding of the wheel hub, in a preferred embodiment of the utility model, the wheel hub body includes an inner core and an anti-slip end cover sleeved on the outer wall of the inner core, and the anti-slip blocks are integrally formed on the outer wall of the anti-slip end cover.

[0012] To ensure the shock absorption effect of the in-wheel motor during use, a number of shock absorption grooves extending axially towards the anti-slip end cover are evenly formed on the side wall of the anti-slip end cover, and the shock absorption grooves are located inside the anti-slip blocks.

[0013] Furthermore, two symmetrically arranged L-shaped shock absorption grooves are respectively formed inside the anti-slip blocks.

[0014] The beneficial effects of the present utility model are as follows: Through the specially designed anti-slip block structure of the cover-type anti-slip wheel hub, when the belt is sleeved outside the wheel hub, the friction between the wheel hub and the belt can be increased, thereby avoiding the relative slipping phenomenon between the two. At the same time, in cooperation with the specially designed shock absorption groove structure, it has a certain deformation ability, thereby improving the shock absorption effect of the in-wheel motor during use and ensuring the comfort during use.

[0017] The following elaborates on the preferred embodiments of the present utility model in detail with reference to the drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. The directional terms mentioned in the present utility model, such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", etc., are only references to the directions of the attached drawings. Therefore, the directional terms used are for explaining and understanding the present utility model, rather than for limiting the present utility model.

[0018] As Figure 1 、 Figure 2 shown, a cover-type anti-slip wheel hub includes a wheel hub body, and the wheel hub body includes an inner core 1 and an anti-slip end cover 2 sleeved on the outer wall of the inner core 1. The inner core 1 and the anti-slip end cover 2 can be integrally formed by welding.

[0019] Specifically, two circles of anti-slip blocks 201 are evenly distributed along the circumferential direction of the outer wall of the anti-slip end cap 2. There is an annular groove 203 that is recessed inward between the two circles of anti-slip blocks 201. The anti-slip blocks 201 are generally rectangular and are integrally formed with the anti-slip end cap 2. The outer walls of the anti-slip blocks 201 are on the same circumference, and the outer walls of the anti-slip blocks 201 are evenly provided with anti-slip grooves that are recessed inward. The two side end faces of the anti-slip blocks 201 are flush with the two side end faces of the anti-slip end cap 2. An inwardly recessed groove 202 is formed between two adjacent anti-slip blocks 201 in the same circle, and the side width of the anti-slip block 201 is greater than the side width of the groove 202. The two sides of the groove 202 penetrate through the two side end faces of the wheel anti-slip end cap 2. The connection between the anti-slip block 201 and the groove 202 is in an arc transition. And one circle of anti-slip blocks 201 is located on one side of the groove 202 between the other circle of anti-slip blocks 201, forming a staggered distribution to ensure the anti-slip effect and at the same time prevent the belt from getting into the groove 202;

[0020] In addition, a plurality of shock-absorbing grooves 204 extending axially toward the anti-slip end cap 2 are evenly provided on the side wall of the anti-slip end cap 2, and the shock-absorbing grooves 204 do not penetrate the anti-slip end cap 2. The shock-absorbing grooves 204 are located inside the anti-slip blocks 201, and the shock-absorbing grooves 204 are two symmetrically arranged L-shaped shock-absorbing grooves.

[0021] Through the specially designed anti-slip block structure of this covered anti-slip wheel hub, when the belt is sleeved outside the wheel hub, the friction between the wheel hub and the belt can be increased, thereby avoiding the relative slipping phenomenon between the two. At the same time, with the specially designed shock-absorbing groove structure, it has a certain deformation ability, thereby improving the shock-absorbing effect when the wheel hub motor is in use and ensuring the comfort during use.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0023] The above embodiments only express several implementation manners of the present invention, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
