[0034] It should also be understood that although the present invention has been described with reference to some specific examples, those skilled in the art will be able to realize many other equivalent forms of the present invention that have the features described in the claims and are therefore within the scope of protection defined thereby.

[0035] The above and other aspects, features and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0036] Specific embodiments of the present invention are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present invention, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present invention. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use the present invention in a variety of ways with substantially any suitable detailed structure.

[0037] The first embodiment of the utility model provides a wheel cover structure, such as Figure 1-Figure 3 As shown, the wheel cover structure includes a splash pad 1 and a baffle 2, the baffle 2 is arranged between the rear end of the splash pad 1 and the body side 100 along the length direction of the vehicle body, a first gap is provided between the front end of the baffle 2 and the splash pad 1 to form a first sound absorbing channel 3, a second gap is provided between the rear end of the baffle 2 and the body side 100 to form a second sound absorbing channel 4, a first sound absorbing member 5 is provided in the first sound absorbing channel 3, and a second sound absorbing member 6 is provided in the second sound absorbing channel 4.

[0038] The splash pad 1 is arranged above the wheel to block the splash and flying stones generated when the wheel is running. For the vehicle model whose wheel well protrudes from the body side 100 in the Y direction, a large cavity structure is formed between the body side 100 near the front door 300 and the rear area of ​​the splash pad 1, and a baffle 2 is arranged in the cavity. Specifically, the baffle 2 is arranged between the rear end of the splash pad 1 and the body side 100, so that a first sound absorption channel 3 is formed between the front end of the baffle 2 and the splash pad 1, and a second sound absorption channel 4 is formed between the rear end of the baffle 2 and the body side 100. A first sound absorption member 5 is arranged in the first sound absorption channel 3, and a second sound absorption member 6 is arranged in the second sound absorption channel 4. After the high-speed airflow reaches the rear of the splash pad 1, it enters the first sound-absorbing channel 3. Compared with the external area, the first sound-absorbing channel 3 is a long and narrow channel. The airflow velocity is reduced when passing through the long and narrow channel. The noise is absorbed by the first sound-absorbing member 5 to achieve the purpose of attenuating wind noise. At the same time, after passing through the splash pad 1, the tire noise is also absorbed by the first sound-absorbing member 5 to achieve the purpose of attenuating tire noise. The high-speed airflow passes through the baffle 2 from the first sound-absorbing channel 3 and then enters the second sound-absorbing channel 4. Compared with the external area, the second sound-absorbing channel 4 is also a long and narrow channel. The airflow velocity is further reduced, and the wind noise is attenuated again and the tire noise is isolated. The first sound-absorbing channel 3, the second sound-absorbing channel 4, the first sound-absorbing member 5 and the second sound-absorbing member 6 effectively reduce wind noise and tire noise, improving the quietness performance of the vehicle.

[0039] At the same time, the baffle 2 and the body side 100 form a double-layer panel structure. Compared with the single-layer sheet metal structure, the sound insulation level of the double-layer panel structure is significantly improved. Specifically, the sound insulation level of the double-layer panel is improved by at least 6dB, thereby further improving the absorption level of tire noise and wind noise.

[0040] In some embodiments, Figure 2 and Figure 4 As shown, the baffle 2 includes a first connection portion 21 that matches the shape of the rear end of the splash pad 1. Specifically, the first connection portion 21 is arranged in an arc shape to match the shape of the rear end of the splash pad 1, so as to enable the high-speed airflow to smoothly enter the first sound absorption channel 3 from the rear end of the splash pad 1, and the first connection portion 21 plays a shielding role on the splash pad 1. The first gap between the first connection portion 21 and the splash pad 1 increases from top to bottom, so that after the first sound absorbing member 5 is installed between the first connection portion 21 and the splash pad 1, the first sound absorption channel 3 is not filled with the first sound absorbing member 5, and the first gap still retains a narrow and long sound absorption channel that can reduce wind noise, ensuring the sound absorption effect on noise.

[0041] In other embodiments, the distance between the first connecting portion 21 and the splash pad 1 along the length direction of the vehicle body is 30 mm (i.e., the distance between the first sound absorbing channel 3 along the length direction of the vehicle body is a fixed value), and the thickness of the first sound absorbing member 5 is set to 10-20 mm. This setting ensures that the first sound absorbing channel 3 is not filled with the first sound absorbing member 5, and a narrow sound absorbing channel that can reduce wind noise is still retained in the first gap, thereby ensuring the sound absorbing effect of noise. The first sound absorbing member 5 is bonded to the baffle 2 or the first sound absorbing member 5 is bonded to the splash pad 1, thereby improving the installation stability of the first sound absorbing member 5.

[0042] In some embodiments, the first sound absorbing member 5 is sound absorbing cotton, which has high sound absorption rate, good sound insulation performance and good heat insulation.

[0043] In some embodiments, Figure 2 , Figure 3 and Figure 6 As shown, at least part of the splash pad 1 is arranged on the lateral outer side of the vehicle body side 100, and a first flange 22 is provided on the lateral outer side of the first connecting portion 21 to shield the splash pad 1 along the width direction of the vehicle body. The first flange 22 includes a shielding portion 221 for shielding the splash pad 1 and a mounting portion 222 for connecting with the splash pad 1, wherein the shielding portion 221 is formed by extending outward laterally along the first connecting portion 21, and the mounting portion 222 is arranged at the edge of the first connecting portion 21 and is bent outward laterally along the shielding portion 221. The shielding portion 221 is provided in the portion of the baffle 2 that is laterally beyond the vehicle body side 100 to shield the rear of the wheel housing, so as to prevent the splash pad 1 and the front wheel well from being exposed to the outside, thereby improving the aesthetics of the vehicle. The baffle 2 is also provided with a mounting portion 222 to achieve stability in the connection between the splash pad 1 and the baffle 2.

[0044] In some embodiments, Figure 3 and Figure 4 As shown, the baffle 2 includes a second connection portion 23 opposite to the side panel body of the vehicle body side panel 100, and the second sound absorbing member 6 seals and connects the second connection portion 23 and the side panel body. There is a second gap between the second connection portion 23 and the splash pad 1 to form a second sound absorbing channel 4, and the second sound absorbing member 6 connects the second connection portion 23 and the side panel body, so that the second sound absorbing channel 4 forms a closed cavity structure. After the high-speed airflow passes through the baffle 2, it enters the second sound absorbing channel 4, and the tire noise is isolated in the sealed cavity. The wind noise is reduced again in the second sound absorbing channel 4 and further absorbed by the second sound absorbing member 6, which greatly reduces the wind noise.

[0045] In some embodiments, the second sound absorbing member 6 is an annular sealing cotton or an annular sealing glue. The second sealing member is set in an annular shape, which is conducive to forming a closed cavity between the side panel body and the second connecting portion 23. Improve the sealing performance of the baffle 2 and the vehicle body side panel 100. Since the distance between the side panel body and the baffle 2 is not fixed, the distance between each position is different. The second sound absorbing member 6 is set to an elastic material, such as elastic sealing cotton or elastic sealing glue. The second sound absorbing member 6 achieves a close fit between the baffle 2 and the second connecting portion 23 under the elastic action, thereby improving the level of absorbing tire noise and wind noise.

[0046] Exemplarily, the distance between the second connecting portion 23 and the splash pad 1 along the length direction of the vehicle body is not less than 30 mm, and the thickness of the second sound absorbing member 6 is 15-60 mm.

[0047] In some embodiments, Figure 5 and Figure 7 As shown, the baffle plate 2 is provided with a first mounting hole 7 connected to the vehicle body side 100, and the splash pad 1 is provided with a second mounting hole 8 connected to the baffle plate 2. A first fixing member (such as a bolt) passes through the first mounting hole 7 to connect the baffle plate 2 and the vehicle body side 100, and a second fixing member passes through the second mounting hole 8 to connect the splash pad 1 and the baffle plate 2, thereby improving the safety performance of the connection between the baffle plate 2 and the vehicle body side 100, and between the splash pad 1 and the baffle plate 2.

[0048] Furthermore, mounting grooves 9 are provided at positions corresponding to the first mounting hole 7 and the second mounting hole 8 on the baffle plate 2 and the splash pad 1, respectively. The mounting groove 9 corresponding to the first mounting hole 7 is provided on the baffle plate 2 and protrudes toward the baffle plate 2, and the mounting groove 9 corresponding to the second mounting hole 8 is provided on the splash pad 1 and protrudes toward the vehicle body side 100. The mounting groove 9 is used to accommodate the first fixing member or the second fixing member, hide the first fixing member and the second fixing member, and improve the aesthetics. At the same time, the mounting groove 9 is provided near the first sound absorbing member 5 and the second sound absorbing member 6, which plays a certain role in limiting and fixing the first sound absorbing member 5 and the second sound absorbing member 6.

[0049] In some embodiments, Figure 2 and Figure 5 As shown, the wheel cover structure further includes a fender 200, and a third gap is provided between the fender 200 and the upper portion of the baffle 2 to form a third sound absorbing channel 10. A third sound absorbing member 11 is provided in the third sound absorbing channel 10, and the third sound absorbing member 11 seals and connects the fender 200 and the upper portion of the baffle 2. The third sound absorbing channel 10 prevents the high-speed airflow of the cabin from impacting the cavity between the door 300 and the body side 100, and the third sound absorbing member 11 is a sealing cotton or a sealing adhesive, which plays a role in sound absorption.

[0050] Specifically, the upper part of the baffle 2 includes a vertical plate portion 24 and a second flange 25 arranged on the edge of the vertical plate portion 24, and the third sound absorbing member 11 is installed in the third sound absorbing channel 10 between the second flange 25 and the fender 200. The second flange 25 is provided with an installation hole 251 connected to the fender 200. The vertical plate portion 24 is formed by extending upward from the top of the first connecting portion 21, and a second flange 25 bent toward the fender 200 is provided at the top of the vertical plate portion 24. The edge profile of the vertical plate portion 24 matches the rear end profile of the fender 200 to close the rear end of the fender 200. The second flange 25 located at the edge of the vertical plate portion 24 is arranged relative to the edge of the fender 6 and has a third gap. The second flange 25 serves as a sealing surface of the fender 200, which facilitates the installation of the third sound absorbing member 11 in the third sound absorbing channel 10 between the second flange 25 and the fender 200, seals the edge of the fender 200 and the baffle 2, and improves the sealing effect of the baffle 2 and the fender 200 while absorbing sound. At the same time, an installation through hole 251 is opened on the second flange 25. The installation through hole 251 is the installation point of the baffle 2, which facilitates the reliable fixed connection of the baffle 2 and the fender 200 by bolts and other fixing members. A certain cavity can be formed between the vertical plate portion 24, the fender 200 and the splash pad 1. After the third sound absorbing member 11 seals the edge of the fender 200 and the baffle 2, it cooperates with the vertical plate portion 24 to block the cavity between the upper part of the splash pad 1 and the fender 200, thereby preventing the high-speed airflow of the cabin from passing through the cavity to impact the door and reducing wind noise. For example, the width of the second flange 25 is 10-20 mm.

[0051] like Figure 1 and Figure 8 As shown, the rear end of the baffle 2 is also connected to the vehicle door 300, which is located on the lateral outer side of the vehicle body side 100. The first flange 22 is provided with a sealing surface connected to the vehicle door 300, and a sealing strip 12 is installed between the sealing surface and the vehicle door 300. The lower part of the first flange 22 is designed as a plane flush with the sheet metal of the vehicle door 300, which can be used as a sealing plane of the sealing strip 12. When the vehicle door 300 is closed, interference sealing can be achieved with the sealing strip 12 of the vehicle door 300.
