[0027] like Figure 1 , Figure 2 and Figure 4As shown, this application provides a car wheel hub protection ring, which includes a wheel hub edge protection part 100 and an anti-detachment insert part 200. The wheel hub edge protection part 100 and the anti-detachment insert part 200 are integrally formed, and the wheel hub edge protection part 100 and the anti-detachment insert part 200 are in a closed ring shape. The anti-detachment insert part 200 is used to be embedded between the car tire 1 and the car wheel hub 2. The wheel hub edge protection part 100 is used to be snapped onto the car wheel hub 2. On the side of the anti-detachment insert part 200 near the car tire 1, there are a plurality of friction pins 210 and a plurality of friction ridges 220 protruding from the surface of the anti-detachment insert part 200.
[0028] In one specific embodiment, the hub edge protection portion is used to protect the edge of the car wheel hub 2. It is installed on the car wheel hub 2 by snap-fitting, which can prevent foreign objects from directly impacting and abrading the edge of the wheel hub. The anti-detachment insert 200 is installed between the car tire 1 and the car wheel hub 2, and its function is to prevent the car wheel hub protection ring from falling off between the tire and the wheel hub. Both are integrally formed and form a closed ring. This structural design allows the car wheel hub protection ring to be tightly installed on the wheel hub and the tire. The friction studs 210 and friction ridges 220 provided on the side of the anti-detachment insert 200 near the car tire 1 are to increase the friction between the insert and the tire, further preventing the car wheel hub protection ring from falling off. The friction studs 210 and friction ridges 220 protrude from the surface of the anti-detachment insert 200 and contact the tire surface, which can effectively increase the contact area and friction.
[0029] like Figure 1 As shown, several friction pins 210 are evenly distributed around the anti-loosening insert 200 to form several rings of different diameters.
[0030] In one specific embodiment, a plurality of friction studs 210 are evenly arranged around the anti-detachment insert 200, forming two rings of different diameters. This distribution allows the friction studs 210 to make more uniform contact with the tire surface, thereby providing stable friction at different positions on the tire. The ring design with different diameters can adapt to the force conditions at different positions on the tire surface, and more rationally distribute the friction force requirements of different parts of the tire during rotation.
[0031] like Figure 2 As shown, the friction nail 210 is in the shape of a four-sided pyramid.
[0032] In one specific embodiment, the friction stud 210 is in the shape of a four-sided pyramid. This shape has unique structural characteristics. The four-sided pyramidal friction stud 210 has a sharp top and a gradually widening bottom. The sharp top can more easily embed into the tiny gaps on the tire surface, increasing the contact depth with the tire and thus improving friction. The gradually widening bottom provides better support, making the friction stud 210 more stable when in contact with the tire and less prone to tilting or breaking. In addition, the four-sided pyramidal shape also has certain advantages in manufacturing, as it can be easily formed through processes such as injection molding.
[0033] like Figure 3 As shown, the thickness of the anti-detachment insert 200 decreases from the side closer to the wheel hub edge protection part 100 to the side farther away from the wheel hub edge protection part 100, so as to prevent the car tire 1 from leaking air.
[0034] In one specific embodiment, the anti-detachment insert 200 is thicker on the side near the wheel hub edge protection portion 100, and gradually thins towards the side away from the wheel hub edge protection portion 100. This thickness variation design is to better adapt to its installation position and functional requirements. During installation, the anti-detachment insert 200 is embedded between the car tire 1 and the car wheel hub 2. The thicker side near the wheel hub edge protection portion 100 provides sufficient support and stability, while the gradually thinning side can better fit the inner surface of the tire, reducing air leakage problems caused by excessive gaps. This gradual thickness design can be optimized according to the actual space and stress conditions between the tire and the wheel hub, allowing the car wheel hub protection ring to better perform its function of preventing tire leakage.
[0035] like Figure 4 As shown, the inner side of the anti-detachment mounting part 200 near the car wheel hub 2 is a concave arc surface, so that the anti-detachment mounting part 200 can fit tightly with the car wheel hub 2.
[0036] In one specific embodiment, the inner side of the anti-detachment insert 200 near the vehicle wheel hub 2 is designed with a concave arc surface. This shape is designed according to the outer surface shape of the vehicle wheel hub 2. The outer surface of the vehicle wheel hub 2 usually has a certain curvature, and the concave arc surface design can better match the outer surface of the wheel hub, allowing the anti-detachment insert 200 to fit tightly onto the wheel hub. This tight fit not only improves the installation stability of the vehicle wheel hub protection ring, but also reduces tire leakage caused by gaps. At the same time, the concave arc surface design also helps the anti-detachment insert 200 to evenly distribute pressure when under stress, improving its overall load-bearing capacity.
[0037] like Figure 5 As shown, a raised strip 300 is provided at the connection between the anti-detachment mounting part 200 and the wheel hub edge protection part 100, and the raised strip 300 is close to the lip of the car wheel hub 2.
[0038] In one specific embodiment, a raised strip 300 is provided at the connection between the anti-detachment insert 200 and the wheel hub edge protection part 100, and this raised strip 300 is close to the lip of the car wheel hub 2. The raised strip 300 is provided to further strengthen the connection between the anti-detachment insert 200 and the wheel hub edge protection part 100. The design of the raised strip 300's position close to the car wheel hub 2 allows it to mate with a specific part of the wheel hub when installing the car wheel hub protection ring, improving the accuracy and stability of the installation. In addition, the presence of the raised strip 300 can also increase the fit between the car wheel hub protection ring and the wheel hub to a certain extent, enhancing the anti-friction effect of the car wheel hub protection ring.
[0039] like Figure 3 As shown, several friction ridges 220 are concentrically arranged and have different diameters.
[0040] In one specific embodiment, several friction ridges 220 are concentrically arranged, meaning they have the same center but different diameters. This concentric arrangement with varying diameters allows the friction ridges 220 to form a multi-layered friction distribution structure on the anti-detachment insert 200. Friction ridges 220 of different diameters can contact different locations on the tire surface, providing corresponding friction based on the force and movement characteristics of different parts of the tire during rotation. For example, the positions near the tire center and near the tire edge have different forces and movement trajectories; using concentric friction ridges 220 of different diameters can better meet the friction requirements of these two locations.
[0041] like Figure 5 As shown, several friction ridges 220 are inclined toward the wheel hub edge protection portion 100, and the angle of inclination of each friction ridge 220 is the same or different.
[0042] In one specific embodiment, several friction ridges 220 are inclined towards the wheel hub edge protection portion 100, and the inclination angle of each friction ridge 220 may be the same or different. This inclination angle design is to better adapt to the movement state and force direction of the tire during rotation. The friction ridges 220 inclined towards the wheel hub edge protection portion 100 can better contact the tire surface and generate friction when the tire rotates, reducing the impact force on the vehicle wheel hub protection ring caused by tire rotation. In this embodiment, the inclination angle of each friction ridge 220 is different. This different inclination angle allows the friction ridges to be optimized according to the force characteristics of different parts of the tire, so that each friction ridge 220 can play its best role. In this embodiment, there are four friction ridges 220, namely the first friction ridge 221, the second friction ridge 222, the third friction ridge 223, and the fourth friction ridge 224. The angle formed between the first friction ridge 221 and the surface of the anti-detachment insert 200 is the first included angle 225, the angle formed between the second friction ridge 222 and the surface of the anti-detachment insert 200 is the second included angle 226, the angle formed between the third friction ridge 223 and the surface of the anti-detachment insert 200 is the third included angle 227, and the angle formed between the fourth friction ridge 224 and the surface of the anti-detachment insert 200 is the fourth included angle 228. The value range of the first included angle 225 is 110 degrees to 120 degrees, the value range of the second included angle 226 is 70 degrees to 80 degrees, the value range of the third included angle 227 is 70 degrees to 80 degrees, and the value range of the fourth included angle 228 is 40 degrees to 50 degrees.
[0043] like Figure 5 As shown, the apex angles of the cross sections of several friction edges 220 are not the same.
[0044] In one specific embodiment, the cross-section of the friction ridge 220 is approximately triangular, and the angle of the apex of each friction ridge 220 is different, resulting in different shapes and areas when each friction ridge 220 contacts the tire surface. This design is to further optimize the friction and contact effect between the friction ridge 220 and the tire, thereby improving the anti-detachment performance of the wheel hub protector and ensuring that the wheel hub protector can be stably installed on the tire and wheel hub under various road conditions and usage conditions. In this embodiment, the apex angle of the cross-section of the first friction ridge 221 is the first apex angle 229, the apex angle of the cross-section of the second friction ridge 222 is the second apex angle 230, the apex angle of the cross-section of the third friction ridge 223 is the third apex angle 231, and the apex angle of the cross-section of the fourth friction ridge 224 is the fourth apex angle 232. The first vertex 229 has a value range of 80 to 90 degrees, the second vertex 230 has a value range of 80 to 90 degrees, the third vertex 231 has a value range of 80 to 90 degrees, and the fourth vertex 232 has a value range of 70 to 80 degrees.
[0045] Car wheel hub protectors are made of polypropylene and / or polyamide.
[0046] In one specific embodiment, the automotive wheel hub protector can be made of polypropylene, polyamide, or a combination of both. Polypropylene is a common thermoplastic with good chemical resistance, impact resistance, and wear resistance, enabling it to withstand various environmental factors during vehicle operation. Polyamide, on the other hand, possesses high strength, high wear resistance, and good self-lubricating properties, which can improve the mechanical properties and service life of the automotive wheel hub protector. Choosing these two materials or a combination thereof to manufacture the automotive wheel hub protector is to fully utilize their respective advantages and meet the various performance requirements of automotive wheel hub protectors in practical use.
