Description

Technical Field

[0001] This utility model relates to the field of wheel hub cover technology, and in particular to a corrosion-resistant automotive wheel hub cover. Background Technology

[0002] Car wheel hubcaps are automotive components that combine functionality and aesthetics. From a functional perspective, their main purpose is to connect and protect the drive shaft inside the wheel hub. They are secured to the inside of the wheel hub with large screws to ensure a stable connection with the drive shaft. In addition, to prevent the screws from loosening or moving, some models also have clips on the screws to increase stability.

[0003] Most car wheel covers on the market are made of a single plastic material (such as ABS or PP). Traditional plastic wheel covers are not corrosion resistant enough. When in contact with rainwater, de-icing agents, oil stains and other media, the surface is prone to chemical corrosion, resulting in fading, cracking and other phenomena. This not only affects the appearance, but also accelerates the corrosion of the wheel hub.

[0004] Secondly, existing hubcaps have limited strength and impact resistance. When they are hit or scratched by road gravel, they are prone to dents, cracks, or even falling off, failing to effectively protect the hubcaps.

[0005] Therefore, a corrosion-resistant automotive hubcap is proposed. Utility Model Content

[0024] 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A corrosion-resistant automotive wheel hub cover includes a hub cover body 1, the hub cover body 1 includes a main body layer 2, a reinforcing support layer 3 is disposed on the surface of the main body layer 2, a buffer energy-absorbing layer 4 is disposed on the surface of the reinforcing support layer 3, and an anti-corrosion intermediate layer 5 is disposed on the surface of the buffer energy-absorbing layer 4, and a wear-resistant outer layer 6 is disposed on the outer side of the anti-corrosion intermediate layer 5.

[0027] In this embodiment: the wear-resistant outer layer 6 resists scratches and abrasions, the anti-corrosion intermediate layer 5 blocks corrosive media, the buffer energy-absorbing layer 4 dissipates impact forces, and the reinforced support layer 3 provides a rigid skeleton. Each layer works together to comprehensively improve the weather resistance and damage resistance of the hubcap body 1. From surface wear resistance to deep corrosion protection, from impact buffering to structural reinforcement, the hubcap body 1 is suitable for various harsh environments such as coastal high-salt, industrial pollution, and complex road conditions, taking into account both functionality and aesthetics. The reinforcing ribs 7 of the reinforced support layer 3 form a stable structure with the main body layer 2, and the annular sealing groove 8 and elastic snap fasteners ensure a firm installation, preventing loosening or falling off due to external forces or corrosion.

[0028] Specifically, such as Figure 2 As shown, the wear-resistant outer layer 6 is composed of a polyetheretherketone coating, and the thickness of the polyetheretherketone coating is 0.5-0.8 mm.

[0029] Specifically, such as Figure 2 As shown, the anti-corrosion intermediate layer 5 is composed of a fluororubber layer, and the thickness of the fluororubber layer is 1-1.5mm.

[0030] Specifically, such as Figure 2 As shown, the buffer energy-absorbing layer 4 is composed of an ethylene-vinyl acetate copolymer layer.

[0031] In this embodiment: the wear-resistant outer layer 6 is composed of a polyetheretherketone (PEEK) coating. The high hardness and low coefficient of friction of the PEEK coating effectively resist the impact of road gravel and the scratches from car wash tools, keeping the surface smooth and preventing the internal materials from being exposed and corroded due to coating damage. Furthermore, the PEEK coating has strong resistance to chemicals such as acids, alkalis, and oils, forming a double chemical protective barrier in conjunction with the anti-corrosion intermediate layer 5. The anti-corrosion intermediate layer 5 is composed of a fluororubber layer. The molecular structure of fluororubber gives it excellent barrier properties against corrosive media such as water, salt solutions, and automobile exhaust, preventing corrosive media from penetrating into the internal structure. In addition, fluororubber has anti-ultraviolet and anti-aging properties, preventing the hub cover body 1 from fading and cracking due to long-term exposure to sunlight and rain, maintaining the integrity of its appearance. The buffer energy-absorbing layer 4 is composed of an ethylene-vinyl acetate copolymer layer. The elastic deformation capability of the ethylene-vinyl acetate copolymer layer allows the hub cover body 1 to absorb and disperse the impact force through its own deformation when encountering road bumps and gravel impacts, reducing damage to the reinforcing support layer 3 and the main body layer 2.

[0032] Specifically, such as Figure 2 As shown, the reinforcing support layer 3 is composed of a carbon fiber reinforced polycarbonate layer.

[0033] Specifically, such as Figure 3 As shown, several reinforcing ribs 7 are evenly distributed along the circumference on the inner side of the reinforcing support layer 3, and the cross-section of the reinforcing ribs 7 is trapezoidal.

[0034] In this embodiment: by strengthening the support layer 3, the tensile and bending strength of the hub cover body 1 can be significantly improved, resisting deformation and cracking caused by external forces. Furthermore, the trapezoidal reinforcing rib 7 and the strengthening support layer 3 work together to improve the ability of the hub cover body 1 to resist radial pressure, preventing dents or deformation.

[0035] Specifically, such as Figure 4 As shown, the edge of the hub cover body 1 is provided with an annular sealing groove 8, and a silicone rubber sealing ring 9 is installed inside the sealing groove 8.

[0036] Specifically, such as Figure 5 As shown, the inner side of the hub cover body 1 is provided with several elastic buckle connectors in a ring shape.

[0037] In this embodiment: a silicone rubber sealing ring 9 is embedded in the annular sealing groove 8 on the edge of the hub cover body 1. The silicone rubber sealing ring 9 is deformed by compression during installation, tightly filling the gap between the hub cover body 1 and the center of the hub, preventing rainwater, mud, and corrosive liquids from seeping in, and protecting the center of the hub from corrosion; elastic buckles are distributed in annularly on the inner side of the hub cover body 1. The elastic buckles quickly engage with the center of the hub through their own elastic deformation, making the installation process simple and generating a continuous fastening force to ensure a reliable connection between the hub cover body 1 and the center of the hub.

[0038] Working principle: During installation, the hubcap body 1 is connected to the center of the car wheel hub via elastic buckle. A silicone rubber sealing ring 9 seals the connection between the two, reducing the intrusion of moisture and dust. When the hubcap body 1 is in use, the anti-corrosion intermediate layer 5 effectively resists the erosion of rainwater, de-icing agents, oil, and other media, while the wear-resistant outer layer 6 further prevents the penetration of corrosive substances. This allows the hubcap body 1 to maintain good performance and extend its service life even under harsh environments. The wear-resistant outer layer 6 has extremely high hardness and wear resistance, resisting the impact of road debris and daily scratches. Simultaneously, the buffer energy-absorbing layer 4 absorbs energy upon impact, reducing damage to the hubcap body 1. Combined with the reinforcing support layer 3, it provides high-strength support, giving the hubcap body 1 excellent impact and deformation resistance, effectively protecting the wheel axle at the center of the wheel hub.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
