Description

Technical Field

[0001] The utility model belongs to the field of automobiles, and in particular relates to a noise-proof and scratch-proof wheel decorative cover and a wheel. Background Art

[0002] The main material of automobile wheel trim covers in related technologies is mostly ABS+PC (engineering plastic alloy) material. When ABS+PC plastic parts are squeezed and rubbed, they are prone to stick-slip phenomenon, thereby generating abnormal friction noise.

[0003] When designing a wheel cap, a circle of supporting ribs is usually added to the outer edge of the cap for axial support, which contacts the wheel. When the cap or wheel is deformed or the driving environment changes, the ribs here will move relative to the wheel, resulting in abnormal noise. At the same time, due to the small contact area of ​​the ribs, the wheels are easily scratched.

[0004] Therefore, how to reduce the abnormal noise generated between the wheel and the trim cover is a technical problem that needs to be solved urgently.

[0005] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

Therefore, a particular feature, structure, or characteristic may be included in more than one embodiment of the present disclosure, so that these phrases do not necessarily refer to the same embodiment. As used herein, the terms "example," "exemplary," and the like are used to "serve as an example, instance, or illustration." Any implementation, aspect, or design described herein as "example" or "exemplary" is not necessarily to be construed as preferred or superior to other implementations, aspects, or designs. On the contrary, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0034] Research has found that when designing wheel covers, a circle of supporting ribs is usually added to the outer edge of the cover for axial support, which contacts the wheel. When the cover or wheel is deformed or the vehicle environment changes during driving, the ribs here will move relative to the wheel, resulting in abnormal noise. At the same time, due to the small contact area of ​​the ribs, the ribs are also easy to scratch the wheel.

[0035] Based on the above research, the disclosed embodiment provides a noise-proof and scratch-resistant wheel cover and wheel. By clamping a support plate on the cover body, the original point contact of the ribs is changed to a surface contact through the support plate, thereby isolating the cover body and the wheel hub from direct contact, effectively solving the potential sticking problem and the abnormal noise problem.

[0036] The defects existing in the above solutions are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article for the above problems should be the contributions made by the inventor to the present invention during the disclosure process.

[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0038] In conjunction with the accompanying drawings, some embodiments of the present utility model are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0039] See also Figure 1 , Figure 1 A schematic diagram of a part of the structure after the noise-proof and scratch-proof wheel cover and the wheel hub 300 are installed is shown. At least one embodiment provides a noise-proof and scratch-proof wheel cover, which is clamped on the wheel hub 300 of the wheel, and includes: a cover body 100 and at least one support plate 200 arranged along the circumference of the cover body 100; the support plate 200 is clamped on the opposite surface of the cover body 100 and the wheel. By clamping the support plate 200 on the cover body 100, the original point contact mode of the ribs is changed to the surface contact mode through the support plate 200, thereby isolating the cover body 100 from direct contact with the wheel hub 300, effectively solving the potential sticking problem and the problem of abnormal noise.

[0040] See also Figure 2 In some embodiments, a clamping member 210 is provided on the support plate 200 ; the support plate 200 is clamped with the decorative cover body 100 via the clamping member 210 .

[0041] Specifically, the clamping member 210 includes a clamping port 211 and a clamping hook 212; the clamping port 211 is provided on the support plate 200; and the clamping hook 212 is provided on the decorative cover body 100. During installation, the clamping port 211 of the support plate 200 is aligned with the clamping hook 212 of the decorative cover body 100, and the support plate 200 is installed by pressing manually or automatically by tooling equipment, thereby completing the fixing of the support plate 200.

[0042] Please continue reading Figure 2 In order to improve the installation strength of the support plate 200, in some embodiments, the number of the clamping members 210 is N, where N is greater than or equal to 2. The number of the clamping members 210 is set according to actual needs.

[0043] Please continue reading Figure 2 In some embodiments, the edge of the decorative cover body 100 extends outwardly in the axial direction to form an annular limiting portion 110; the top surface of the support plate 200 abuts against the annular limiting portion 110. The support plate 200 is limited by the abutment of the annular limiting portion 110, thereby preventing the support plate 200 from shaking in the radial direction when the wheel hub 300 rotates.

[0044] In a preferred embodiment, the annular limiting portion 110 is composed of a plurality of arc-shaped protrusions 111. The multi-stage arc-shaped protrusions 111 are used to limit the support plate 200, thereby reducing the material used for the decorative cover and reducing the overall cost of the decorative cover.

[0045] Please continue reading Figure 1 In a preferred embodiment, the protrusion height of the annular limiting portion 110 is less than the thickness of the support plate 200, so that there is a gap between the annular limiting portion 110 and the wheel hub 300. Since there is a gap between the annular limiting portion 110 and the wheel hub 300, direct contact between the decorative cover body 100 and the wheel hub 300 is avoided.

[0046] In a preferred embodiment, a lubricating layer is provided on the contact surface between the support plate 200 and the hub 300. Specifically, the support plate 200 is made of POM (polyoxymethylene resin) material. Since the POM material has excellent self-lubricating properties, a lubricating layer is formed on the support plate 200, thereby solving the potential sticking problem and the abnormal noise problem.

[0047] In a preferred embodiment, there are multiple support plates 200 , and the multiple support plates 200 are evenly distributed along the circumference of the decorative cover body 100 .

[0048] See also Figure 3At least one embodiment further provides a wheel, including a wheel hub 300 and the above-mentioned noise-proof and scratch-proof wheel cover; the noise-proof and scratch-proof wheel cover is clamped on the wheel hub 300. By clamping the support plate 200 on the cover body 100, the original point contact of the ribs is changed to a surface contact through the support plate 200, thereby isolating the cover body 100 from direct contact with the wheel hub 300, effectively solving the potential sticking problem and the problem of abnormal noise.
