Technical Field
[0001] This utility model relates to the field of wheel hub technology, specifically a protective wheel hub. Background Technology
[0002] A wheel rim is a cylindrical metal component, centered on an axle, that supports the tire. 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. Wheel rims are commonly used in photovoltaic applications in the automotive and motorcycle industries.
[0003] Existing wheel hubs typically consist of an inner hub, reinforcing ribs, and spoke seats. Since the surface of the wheel hub lacks a protective structure, when a car or motorcycle drives on a road with stones, stones fly up and penetrate the wheel hub, damaging the axle and reducing the wheel hub's protective effect. At the same time, when a car is reversing, it is easy to scrape against the curb, causing damage to the wheel hub and reducing its service life.
[0004] According to announcement number CN221497511U, a wheel hub includes a rim, an axle located at the center of the inner side of the rim, a main spoke fixedly mounted on the upper side of the axle, and secondary spokes mounted on the front and rear sides of the axle. Multiple auxiliary components are arranged between the two secondary spokes and the front and rear of the main spokes. The main spoke includes a support ring located on the outer side of the center of the axle, with multiple main spokes evenly arranged around its outer side. Multiple arc-shaped support plates are evenly arranged on the inner side of the rim, with the inner side of each arc-shaped support plate connected to the other end of the main spokes. The main spoke is integrally formed with the rim and axle. The secondary spokes include a mounting plate detachably mounted on the axle, with a spoke plate fixedly mounted on the outer side of the mounting plate. Multiple sets of brackets are evenly arranged on the outer side of the spoke plate, and each set of brackets is connected to the rim. This design improves the overall integrity of the wheel hub, extends its lifespan, and makes it safer and more reliable to use.
[0005] As described above, when a car drives on a road with stones, the stones fly up and can damage the axle by passing through the wheel hub, reducing the wheel hub's protective effect. At the same time, when reversing, the wheel hub is prone to scraping against the curb, causing damage and reducing its service life. Therefore, we need to propose a protective wheel hub.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-5This utility model provides a technical solution: a protective wheel hub, including an inner wheel hub 1, a reinforcing structure 2 for strengthening the stability of the wheel hub provided on the outer surface of the inner wheel hub 1, a carbon fiber wheel hub cover 3 for protecting the wheel hub provided on the top of the inner wheel hub 1, a disassembly and assembly structure 4 for easy disassembly and assembly provided at the bottom of the carbon fiber wheel hub cover 3, a spoke seat 5 provided in the inner cavity of the inner wheel hub 1, a reinforcing rib 6 welded on the outer surface of the spoke seat 5, the other end of the reinforcing rib 6 being welded and fixed to the inner side wall of the inner wheel hub 1, several sets of reinforcing ribs 6 being provided, a metal protective mesh 7 for preventing stones from splashing into the wheel hub between every two sets of reinforcing ribs 6, bolt holes 8 being opened on the upper surface of the spoke seat 5, and a sealing structure 9 for sealing the bolt holes 8 being provided on the top of the spoke seat 5.
[0024] This invention strengthens the wheel hub by reinforcing the structure 2, seals the bolts connecting the wheel hub and axle with the sealing structure 9 to prevent corrosion from rainwater, and protects the inner wheel hub 1 by providing a carbon fiber wheel hub cover 3. When parked, the carbon fiber wheel hub cover 3 contacts the curb first, preventing the inner wheel hub 1 from directly contacting the curb, thus protecting the inner wheel hub 1. The metal protective mesh 7, in conjunction with several sets of reinforcing ribs 6, blocks flying stones, preventing them from penetrating the wheel hub and damaging the axle. This improves the wheel hub's protection of the axle, extends its service life, and protects the wheel hub.
[0025] Furthermore, the reinforcing structure 2 includes an aluminum alloy outer rim 21, with an aluminum alloy inner rim 22 welded to its inner cavity. The inner wall of the aluminum alloy inner rim 22 is welded and fixed to the outer surface of the inner hub 1. This design reinforces and protects the outer surface of the inner hub 1 by wrapping it with the aluminum alloy inner rim 22, and strengthens the inner rim 22 by the aluminum alloy outer rim 21, thus increasing the protective effect of the inner rim 22 on the hub.
[0026] Furthermore, a buffer groove 10 is formed on the outer surface of the aluminum alloy inner rim 22. Several sets of buffer grooves 10 are distributed around the center on the outer surface of the aluminum alloy inner rim 22. With this design, when the aluminum alloy outer rim 21 is compressed, the compressive force is dispersed through the buffer grooves 10 and then transmitted to the aluminum alloy inner rim 22. The force is then evenly transmitted to the inner hub 1 through the inner rim 22, reducing the compressive force on the inner hub 1 and protecting it.
[0027] Furthermore, the disassembly and assembly structure 4 includes a connecting plate 41 and a connecting seat 42. The connecting plate 41 is fixedly connected to the bottom end of the carbon fiber wheel hub cover 3, and the connecting seat 42 is welded to the inner sidewall of the inner wheel hub 1. A connecting groove 43 is formed on the surface of the connecting seat 42, and the surface of the connecting plate 41 mates with the inner cavity of the connecting groove 43. Threaded holes are formed on the surfaces of both the connecting plate 41 and the connecting seat 42. With this design, when the carbon fiber wheel hub cover 3 is installed, the connecting plate 41 is inserted into the inner cavity of the connecting groove 43, and then the threaded holes on the connecting plate 41 and the connecting seat 42 are aligned. The connecting plate 41 is then fixed to the inner cavity of the connecting groove 43 by tightening screws, thus facilitating disassembly and assembly and improving the stability of the carbon fiber wheel hub cover 3 on the inner wheel hub 1.
[0028] Furthermore, the sealing structure 9 includes a spoke cover 91, with a sealing gasket 92 at its top. The outer surface of the sealing gasket 92 is in contact with the inner wall of the spoke seat 5. A locking block 93 is fixedly connected to the lower surface of the spoke cover 91, and a retaining ring 94 is provided in the inner cavity of the spoke seat 5. The surface of the locking block 93 engages with the inner cavity of the retaining ring 94. With this design, when the spoke cover 91 is closed, the locking block 93 is inserted into the inner cavity of the retaining groove. Rotating the spoke cover 91 causes the locking block 93 to engage with the retaining groove, thus fixing the spoke cover 91. Simultaneously, the sealing gasket 92 seals the inner cavity of the spoke seat 5, fixing the mounting holes on the spoke seat 5.
[0029] Furthermore, the outer surface of the carbon fiber wheel cover 3 is coated with a self-healing coating, the thickness of which is set to 0.1-0.5mm. With this design, the self-healing coating ensures that when the carbon fiber wheel cover 3 rubs against a curb, the scratches will disappear after a short period of time, increasing wheel protection and improving aesthetics.
[0030] Furthermore, the upper surface of the carbon fiber hubcap 3 is provided with heat dissipation holes 11, which are elliptical in shape and arranged in several groups. This design, through the placement of the heat dissipation holes 11, allows the inner hubcap 1 to dissipate heat normally while protecting it, reducing the impact on the inner hubcap 1. When using it on a motorcycle, the carbon fiber hubcap 3 needs to be removed before it can be installed and used on the motorcycle.
[0031] In practical use: When the car is moving, stones are squeezed and splashed. After passing through the carbon fiber hubcap 3, the stones are blocked by the metal protective mesh 7, isolating them outside the hub and preventing them from colliding with the axle. When a scratch occurs, the carbon fiber hubcap 3 first contacts the curb, preventing the inner hub 1 from directly contacting the curb, thus protecting the inner hub 1. After a scratch, the self-healing coating on the carbon fiber hubcap 3 makes the scratch marks on its surface disappear, thus protecting the hub and improving its protection of the axle, extending the service life of the hub.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
