It should also be noted that the aforementioned Y-axis representation is intended solely for the purpose of facilitating and simplifying the description of the present invention, and does not indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, it should not be construed as limiting the present invention.

[0028] like Figure 1-Figure 2 As shown, a wheel decorative cover according to an embodiment of the present invention includes a cover plate 1 and a heat-insulating retaining ring 2. The cover plate 1 includes a cover plate body 11 and a connecting column 12. One end face of the cover plate body 11 is provided with the connecting column 12 extending along its thickness direction. The heat-insulating retaining ring 2 is sleeved on the outside of the connecting column 12, and the connecting column 12 is used to be clamped with the inner wall of the rim 3 through the heat-insulating retaining ring 2.

[0029] Specifically, the rim 3 is a cylindrical structure with open ends. The axis of the rim 3 is arranged along the left-right direction of the vehicle, that is, the Y direction of the vehicle. The cross-sectional dimensions of the rim 3 vary at different points along its axis. Specifically, the cross-sectional dimensions are smaller in the middle and larger at the ends, forming a structure that is thin in the middle and thick at the ends. One axial end of the rim 3, or more precisely, the end facing the outside of the vehicle, is equipped with a wheel cover. The interior of the rim 3 is connected to the wheel hub via spokes 4, as shown in FIG. Figure 5 As shown, the outer portion of the rim 3 is covered with a tire.

[0030] The cover plate body 11 is generally circular, matching the shape of the corresponding open end face of the rim 3 and covering the internal structure of the rim 3. The thickness of the cover plate body 11 is oriented in the vehicle's left-right direction, or the vehicle's Y-direction. A connecting post 12 is provided on the end face of the cover plate body 11 facing the vehicle's interior. The connecting post 12 can be integrally formed with the cover plate body 11 and extends along the Y-direction. The thermal insulation retainer 2 can be annular and aligns with the thickness of the cover plate 1, both extending along the Y-direction.

[0031] In this embodiment, the connecting column 12 of the cover plate 1 is clamped with the inner wall of the rim 3 through the heat-insulating retaining ring 2, thereby realizing the connection between the cover plate 1 and the rim 3, realizing the function of the ordinary wheel decorative cover to decorate the wheel and protect the hub and spokes; at the same time, the cover plate 1 does not directly contact the rim 3, but contacts the rim 3 through the heat-insulating retaining ring 2, and the heat-insulating retaining ring 2 has heat-resistant performance and can insulate, thereby preventing the heat on the rim 3 from being transferred to the cover plate 1 and causing it to deform and melt, thereby extending the service life of the wheel decorative cover and enhancing the applicability of the wheel decorative cover at different temperatures; moreover, compared with the entire wheel decorative cover being made of a higher-cost heat-resistant material, the utility model, by configuring the wheel decorative cover to include two parts, the cover plate 1 and the heat-insulating retaining ring 2, only the heat-insulating retaining ring 2 needs to be made of a higher-cost heat-resistant material, and the cover plate 1 can still be made of a lower-cost material, thereby reducing the overall production cost.

[0032] It should be noted that, during assembly, the heat insulating retaining ring 2 may be first clamped to the inner wall of the rim 3 , and then the connecting column 12 of the cover plate 1 may be inserted into the central hole 22 of the heat insulating retaining ring 2 .

[0033] Optionally, the heat-insulating retaining ring 2 is made of an elastic material and can undergo elastic deformation, thereby reducing abnormal noise during assembly between the heat-insulating retaining ring 2, the cover plate 1, and the rim 3, as well as vibration and abnormal noise during vehicle driving, thereby improving the driving experience.

[0034] Optionally, the heat-insulating retaining ring 2 is made of heat-resistant polypropylene; and / or the cover plate 1 is made of polycarbonate and acrylonitrile-butadiene-styrene.

[0035] In this embodiment, the heat-insulating retaining ring 2 is made of heat-resistant polypropylene, also known as heat-resistant PP material, which has excellent heat resistance, tensile strength, and toughness, and is lightweight. The cover plate 1 is made of polycarbonate (PC) and acrylonitrile-butadiene-styrene (ABS), which are easy to injection mold and relatively low in cost.

[0036] like Figure 2 As shown, optionally, a plurality of ventilation holes 21 are provided at intervals in the circumferential direction of the thermal insulation retaining ring 2 , and the ventilation holes 21 are provided through the thermal insulation retaining ring 2 in the thickness direction.

[0037] In this embodiment, the thermal insulation ring 2 is provided with ventilation holes 21 at evenly spaced intervals around its circumference. This improves the heat dissipation efficiency of the thermal insulation ring 2 and prevents heat accumulation within the ring 2. Furthermore, it enhances the ring's deformability, reducing noise during wheel cover assembly and vibration during vehicle operation. The ventilation holes 21 can be circular holes extending through the thickness of the thermal insulation ring 2. Multiple ventilation holes 21 can be evenly spaced around the circumference of the ring 2 to achieve uniform heat dissipation.

[0038] like Figure 2-Figure 4 As shown, optionally, the thermal insulation retaining ring 2 has a center hole 22, and the end of the connecting column 12 away from the cover body 11 is provided with a clamping block 121, and the clamping block 121 is arranged toward the outside of the connecting column 12, and one end of the connecting column 12 passes through the center hole 22 so that the clamping block 121 abuts against the end face of the thermal insulation retaining ring 2.

[0039] Specifically, the center hole 22 is a circular hole that matches the shape of the connecting column 12. The end of the connecting column 12 away from the cover body 11, that is, the end facing the interior of the vehicle, is provided with a snap-in block 121. The snap-in block 121 is arranged toward the outside of the connecting column 12, that is, away from the axis of the connecting column 12.

[0040] In this embodiment, the connecting column 12 and / or the thermal insulation retaining ring 2 can be deformed, and the end of the connecting column 12 with the clamping block 121 can pass through the center hole 22 under the action of external force until the clamping block 121 abuts against the end face of the thermal insulation retaining ring 2 away from the cover body 11, so as to achieve the clamping of the thermal insulation retaining ring 2 and the cover plate 1 along the Y direction, and prevent the cover plate 1 from separating from the thermal insulation retaining ring 2 or the rim 3 along the Y direction.

[0041] like Figure 4 As shown, optionally, the circumferential edge of the heat-insulating retaining ring 2 is provided with an arc-shaped protrusion 23 protruding radially outward, and the inner wall of the rim 3 is provided with an arc-shaped groove 31 , and the arc-shaped protrusion 23 matches the arc-shaped groove 31 .

[0042] In this embodiment, the arc-shaped protrusion 23 protruding from the circumferential edge of the heat-insulating retaining ring 2 cooperates with the arc-shaped groove 31 on the rim 3 to achieve snap-fit ​​assembly between the heat-insulating retaining ring 2 and the rim 3. Furthermore, compared to providing a rectangular groove on the sidewall of the rim 3, providing the arc-shaped groove 31 on the sidewall of the rim 3 allows for a smooth transition between the arc-shaped groove 31 and the rest of the rim 3, thus avoiding local stress concentration and protecting the rim 3 from damage.

[0043] like Figure 3 As shown, the interior of the connecting column 12 is optionally hollow. This reduces material usage and costs, and enhances the elastic deformation capability of the connecting column 12, so that the connecting column 12 can be squeezed and deformed when inserted into the center hole 22 of the thermal insulation retaining ring 2 under external force, and recover after the external force is removed.

[0044] Optionally, the connecting column 12 is provided with a plurality of deformation notches (not shown) at intervals along its circumference. The deformation notches can separate the connecting column 12 into a plurality of connecting segments spaced apart along its circumference. Providing deformation notches on the connecting column 12 enhances its deformation capability, allowing the connecting column 12 of the cover plate 1 to be more smoothly engaged with the thermal insulation retaining ring 2.

[0045] Another embodiment of the present invention provides a wheel assembly comprising a rim 3, a tire, and the aforementioned wheel cover. The tire is mounted on the exterior of the rim 3, and the wheel cover is mounted on the side of the rim 3 facing the vehicle exterior. Spokes 4 are disposed within the rim 3 and can be secured to the wheel hub. The advantages of this wheel assembly over existing technologies are the same as those of the aforementioned wheel cover and will not be repeated here.

[0046] Another embodiment of the present invention provides a vehicle including the aforementioned wheel assembly. The advantages of the vehicle compared to the prior art are the same as those of the aforementioned wheel assembly, and thus will not be described again.

[0047] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
