[0012] (III) Beneficial Effects

[0013] This utility model provides a modular, easily detachable automotive wheel hub decorative cover. It has the following advantages:

[0014] (i) The modular and easily detachable car wheel hub decorative cover, by setting a main wheel disc, the air cutting blades of the annular array on the outer wall of the main wheel disc and the air guide grooves in the wall form a heat dissipation channel, which can guide the airflow evenly through the wheel hub area, reduce driving wind resistance and improve the heat dissipation efficiency of the wheel hub, and reduce the risk of overheating of the braking system.

[0022] 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.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a modular, easily detachable car wheel hub decorative cover, including a main wheel assembly 1 and an installation assembly 2. The installation assembly 2 includes a secondary wheel disc 21. A rubber pad 23 is fixedly connected to the outer wall of the secondary wheel disc 21. The elasticity of the rubber pad 23 can compensate for minor errors during installation. Anti-slip pads 24 are arranged in a circular array along the central axis of the rubber pad 23, increasing the friction at the contact point with the wheel hub and preventing the decorative cover from loosening during driving. The anti-slip pads 24 are fixedly connected to the outer wall of the rubber pad 23 and are arranged in a circular array along the central axis of the rubber pad 23. A through hole 22 is opened in the wall of the secondary wheel disc 21 and is arranged in a circular array along the central axis of the secondary wheel disc 21.

[0024] The main wheel assembly 1 includes a main wheel disk 11. A cutter blade 12 is fixedly connected to the outer wall of the main wheel disk 11, and the cutter blade 12 is arranged in a circular array along the central axis of the main wheel disk 11. A buckle 15 is fixedly connected to the outer wall of the main wheel disk 11, and the buckle 15 is arranged in a circular array along the central axis of the main wheel disk 11. An air guide groove 14 is provided in the wall of the main wheel disk 11, and the air guide groove 14 is arranged in a circular array along the central axis of the main wheel disk 11. An arc groove 16 is provided in the wall of the main wheel disk 11. By rotating the secondary wheel disk 21 to squeeze the hub, the axial thrust of the secondary wheel disk 21 is transmitted through the central axis of the main wheel disk 11, causing the arc groove 16 at the edge of the main wheel disk 11 to contract and deform, causing the end of the buckle 15 to move slightly towards the center, forming a wedge tightening effect. The wall of the main wheel disk 11 is threadedly connected to the outer wall of the secondary wheel disk 21 through a threaded groove 13, and the threaded groove 13 is provided in the wall of the main wheel disk 11.

[0025] This modular, easily detachable automotive wheel hub cover achieves both decorative and functional purposes through the structural cooperation between the main wheel assembly 1 and the mounting assembly 2. The outer wall of the main wheel disc 11 in the main wheel assembly 1 is equipped with air-cutting blades 12. When the car is moving, airflow flows along the air-cutting blades 12. The circular array of air-cutting blades 12 along the central axis of the main wheel disc 11 guides the airflow evenly, reducing air resistance and providing some heat dissipation for the wheel hub. The air guide slots 14 opened in the wall of the main wheel disc 11 further optimize the airflow path and enhance the heat dissipation effect.

[0026] During installation, the threaded groove 13 in the wall of the main wheel 11 is connected to the threaded connection on the outer wall of the secondary wheel 21 to fix the secondary wheel 21 to the main wheel 11. The rubber pad 23 and anti-slip pad 24 on the outer wall of the secondary wheel 21 play a buffering and anti-slip role. The elasticity of the rubber pad 23 can compensate for minor errors during installation. The anti-slip pad 24 is arranged in a ring array along the central axis of the rubber pad 23, which increases the friction at the contact point with the wheel hub and prevents the decorative cover from loosening during driving. The through hole 22 in the wall of the secondary wheel 21 can reduce the overall weight of the decorative cover without affecting its structural strength.

[0027] The buckles 15 on the outer wall of the main wheel 11 are arranged in a circular array along the central axis. When installed on the hub, the buckles 15 engage with the edge of the hub to achieve quick positioning and initial fixation. An arc groove 16 is provided on the main wheel 11, which allows the main wheel 11 to have elastic movement space. Thus, after the buckles 15 on the main wheel 11 engage with the edge of the hub, the hub can be squeezed by rotating the secondary wheel 21. The axial thrust of the secondary wheel 21 is transmitted through the central axis of the main wheel 11, causing the arc groove 16 on the edge of the main wheel 11 to contract and deform, which drives the end of the buckle 15 to move slightly towards the center, forming a wedge effect. When disassembly is required, the secondary wheel 21 is rotated in the opposite direction. After the pressure of the secondary wheel 21 on the hub decreases, the driving force on the main wheel 11 is stopped. Then the main wheel 11 can be removed from the hub. Due to the modular design, the disassembly process is convenient and quick and will not damage the hub.
