[0002] A wheel rim is a cylindrical metal component that supports the tire and is mounted on an axle. It is also called a wheel rim, steel rim, wheel hub, or tire rim. Wheel rims come in many varieties depending on their diameter, width, molding method, and materials.

[0003] For example, a deformation-resistant wheel hub with publication number CN215153623U includes a rim, a reinforcing layer fixedly connected to the inner side of the rim, spokes fixedly connected at equal intervals to the inner wall of the reinforcing layer, a hub component fixedly connected to the inner side of the spokes, a reinforcing layer fixedly connected to the outer side of the hub component, fixing strips fixedly connected to both sides of the spokes, a fixing block fixedly connected to the rear end of the spokes, and both ends of the fixing block fixedly connected to the fixing strips.

[0004] As shown in the above wheel hub, the existing wheel hub protective plates are all fixed to the wheel hub with bolts. When the wheel hub is in use, water stains and mud can easily enter the threaded holes and corrode the bolts and protective plates, thus reducing their service life. Utility Model Content

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0025] The basic structure of a wheel hub includes:

[0026] Figure 1 and Figure 2 As shown, a center cover is fixedly connected to the center point of the wheel hub body 1 by bolts.

[0027] The innovative structure of this utility model for a novel porous wheel hub is as follows:

[0028] Figure 1 and Figure 2 As shown, an upper cover 2 and a lower cover 3, which are mounted on the center cover, are fixedly connected to both sides of the hub body 1, and the upper cover 2 and the lower cover 3 are fixedly connected to each other.

[0029] Figure 1 and Figure 2 As shown, by setting the upper cover 2 and the lower cover 3, most of the water stains can be prevented from entering the bolts and accelerating their aging. This design can protect the wheel hub body 1.

[0030] Connection structure between upper cover 2 and lower cover 3:

[0031] Figures 1-3As shown, the upper cover 2 and the side wall near the wheel hub body 1 are provided with several connecting blocks 4, and each connecting block 4 is provided with a slot 8. The lower cover 3 is provided with several plug-in parts 5 near the wheel hub body 1. When the upper cover 2 and the lower cover 3 are assembled, the plug-in parts 5 are inserted into the slot 8.

[0032] Figures 1-3 As shown, when assembling the upper cover 2 and the lower cover 3, the upper cover 2 and the lower cover 3 are placed on both sides of the wheel hub body 1 and the connector 5 is aligned with the slot 8 and inserted. At this time, the connector 5 passes through the wheel hub body 1, so that the upper cover 2 and the lower cover 3 are connected together. This design serves to connect the upper cover 2 and the lower cover 3.

[0033] Figures 1-3 As shown, the upper cover 2 and the connecting block 4, as well as the lower cover 3 and the plug-in 5, are all integrally formed, which can reduce manufacturing difficulty and manufacturing cost.

[0034] The fixing structure between the upper cover 2 and the lower cover 3:

[0035] Figures 2-5 As shown, a locking block 11 is slidably connected in the slot 8, and a sliding groove 12 is provided on the inner wall of the slot 8. The locking block 11 slides in the sliding groove 12. A spring 13 is fixedly connected between the sliding groove 12 and the locking block 11. A slot 14 is provided on the connector 5 to facilitate the locking block 11 to be inserted. When the connector 5 enters the slot 8, the locking block 11 slides into the sliding groove 12 and the spring 13 deforms. When the locking block 11 is inserted into the slot 14, the upper cover 2 and the lower cover 3 are fixed.

[0036] Figures 2-5 As shown, during the process of inserting the connector 5 into the slot 8, the locking block 11 slides into the slide groove 12 due to the push of the inner wall of the slot 8. At this time, the spring 13 deforms due to compression. When the locking block 11 is opposite to the slot 14, the locking block 11 slides out of the slide groove 12 and is locked into the slot 14 due to the push of the deformed spring 13, thereby fixing the connector 5 in the slot 8 and fixing the upper cover 2 and the lower cover 3 together.

[0037] Figures 2-5 As shown, the card block 11 has a guide slope on the side near the connector 5, which allows the card block 11 to be pushed into the slide groove 12 more smoothly along the guide slope when the connector 5 enters the slot 8, thus improving the ease of operation.

[0038] The split structure of the upper and lower shells:

[0039] Figures 2-5 As shown, a disassembly component is slidably connected to the lower cover 3. The disassembly component includes several slide rods 7. One end of the slide rod 7 extends into the slot 14. A push block 9 is integrally formed on the end of the slide rod 7 near the slot 14. When the upper cover 2 and the lower cover 3 are disassembled, the push block 9 slides into the slot 14 and pushes the slot block 11 into the slide groove 12.

[0040] Figures 2-5 As shown, when replacing the upper cover 2 and the lower cover 3, push the slide bar 7 inward so that one end of the slide bar 7 gradually slides into the slot 14 and pushes the locking block 11, which is locked in the slot 14, into the slide groove 12. At this time, the locking block 11 separates from the slot 14, thereby releasing the fixation between the upper cover 2 and the lower cover 3, making it easier to replace the upper cover 2 and the lower cover 3.

[0041] Figures 2-5 As shown, each slide bar 7 is fixedly connected with a protrusion 16, and both the locking block 11 and the locking groove 14 are provided with arc-shaped surfaces. The lower cover 3 is provided with a groove 15 to facilitate the insertion of the protrusion 16. When the protrusion 16 is inserted into the groove 15, the push block 9 separates from the slide groove 12.

[0042] Figures 2-5 As shown, when the upper cover 2 and the lower cover 3 are assembled, the push block 9 separates from the slide groove 12 and the protrusion 16 engages with the groove 15, thereby fixing the slide rod 7 and preventing the slide rod 7 from sliding when the wheel hub is in use.

[0043] Figures 2-5 As shown, several sliding rods 7 are connected to a ring 6 at the end away from the push block 9. By sliding the ring 6, all the sliding rods 7 can be moved to slide together at the same time. This design improves the ease of operation.

[0044] Figures 2-5 As shown, several return springs 10 are fixedly connected between the ring 6 and the lower cover 3. When the ring 6 is pushed inward to make the push block 9 slide into the slide groove 12 to end the fixation between the upper cover 2 and the lower cover 3, the return spring 10 deforms. After contact fixation, the return spring 10 pushes the ring 6 to reset, which facilitates the next use. Furthermore, the presence of the return spring 10 can further prevent the slide rod 7 from sliding when the hub is in use.

[0045] The present invention provides a novel multi-hole wheel hub. Specific examples have been used to illustrate the principle and implementation of the invention. The descriptions of these embodiments are merely for the purpose of helping to understand the invention and its core concepts. It should be noted that those skilled in the art can make various improvements and modifications to the invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
