Description

Technical Field

[0001] The utility model belongs to the technical field of automobile manufacturing, and more specifically relates to an automobile wheel air deflector and an automobile. Background Art

[0002] Reducing a car's wind resistance can reduce its driving resistance and energy consumption, thereby increasing its range. When a car is traveling at high speed, airflow impacts the rapidly rotating tires, causing turbulence around the tires and increasing the vehicle's wind resistance. Prior art uses air deflectors in front of the wheels to guide airflow away from the rotating tires, reducing airflow entering the wheel cavity, thereby reducing vortices around the tires and reducing overall vehicle wind resistance. However, current air deflectors on the market are typically straight, resulting in poor airflow guidance and ineffective reduction of overall vehicle wind resistance. Utility Model Content

[0009] Furthermore, the energy absorbing notch is arranged perpendicular to the forward direction of the vehicle.

[0010] Furthermore, the energy absorbing notch is arranged at the rear end of the guide portion.

[0034] The following describes preferred embodiments of the present invention in greater detail. Although preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0035] Example 1

[0036] The utility model provides a car wheel wind deflector, such as Figure 1-4 As shown, including:

[0037] The guide portion 1 has a guide surface 11, which is a streamlined curved surface and is inclined downward from the front end to the rear end; the front end is one end in the direction of the vehicle's forward movement, and the rear end is the other end opposite to the front end;

[0038] The mounting portion 2 is fixedly connected to the upper end of the air guide portion 1 and is used to mount the air guide portion 1 in front of the wheel 31 .

[0039] Specifically, considering the aerodynamic performance of the entire vehicle, the guide part 1 is designed to be ship-shaped and arranged in front of the wheel 31. It can guide the airflow, prevent the airflow from directly impacting the rotating tire, reduce the airflow entering the wheel cavity, and thus reduce the vortex generated around the tire. It can effectively reduce the vehicle's drag coefficient by 0.01, thereby reducing the car's driving resistance and energy consumption, enhancing the car's power economy, and increasing the cruising range by 6-8km.

[0040] In this embodiment, the guide portion 1 further includes a side wall connected to the outer periphery of the guide surface 11, so that the guide portion 1 forms a boat shape.

[0041] Optionally, the guide portion 1 is provided with an energy-absorbing notch 12 to improve the deformation capability of the guide portion 1 .

[0042] Specifically, when the vehicle comes into contact with the road surface or obstacles while traveling on a poor road condition, the energy-absorbing notch 12 can weaken the local strength of the guide portion 1 , thereby improving the deformation capability of the guide portion 1 and avoiding damage.

[0043] Optionally, the energy absorbing notch 12 is in the shape of an elongated strip.

[0044] Specifically, the energy-absorbing notch 12 is configured as a long strip, which can further improve the deformation capability of the air guide portion 1 .

[0045] Optionally, the energy absorbing notch 12 is arranged perpendicular to the forward direction of the vehicle.

[0046] Specifically, the long energy-absorbing notch 12 is arranged perpendicular to the forward direction of the vehicle, and can further improve the deformation capacity of the guide portion 1 when the vehicle encounters a front or rear collision.

[0047] Optionally, the energy absorbing notch 12 is provided at the rear end of the air guide portion 1 .

[0048] Specifically, since the rear end size of the air guide portion 1 is larger than the front end size, arranging the energy absorbing notch 12 at the rear end of the air guide portion 1 can increase the size of the energy absorbing notch 12 and improve the energy absorbing effect.

[0049] In this embodiment, the energy absorbing notch 12 is provided on the guide surface 11 at the rear end of the guide portion 1 and at least a portion of the side wall.

[0050] Alternatively, as Figure 5 As shown, when the automobile wheel deflector is installed in front of the front wheel 31, the mounting portion 2 includes:

[0051] The mounting plate 22 is an annular structure, arranged around the mounting portion 2 and extending horizontally toward the outside of the mounting portion 2;

[0052] The first positioning mounting hole 23 is provided at the front end of the mounting plate 22 and is used to connect with the front bumper lower guard plate 32 of the vehicle body;

[0053] The second positioning mounting hole 24 is provided at the rear end of the mounting plate 22 and is used to connect with the wheel cover liner 33 of the vehicle body;

[0054] The door-shaped buckle 25 is provided in the middle of the mounting plate 22 and is used to connect with the front bumper lower guard plate 32 of the vehicle body.

[0055] In this embodiment, the first positioning mounting hole 23 mounts the mounting plate 22 on the front bumper lower guard plate 32 through self-tapping screws, and the second positioning mounting hole 24 mounts the mounting plate 22 on the wheel cover gasket 33 through self-tapping screws. The door-shaped buckle 25 is fixed to the front bumper lower guard plate 32 by a snap-fit method. Through the mounting part 2 structure, the deflector 1 can be installed in front of the front wheel 31, effectively reducing the vehicle's wind resistance.

[0056] Optionally, the first positioning and mounting holes 23 are a pair, the second positioning and mounting holes 24 are three pairs, and the door-shaped buckles 25 are a pair.

[0057] Specifically, the first positioning and mounting holes 23 , the second positioning and mounting holes 24 and the door-shaped buckles 25 are all arranged in pairs, making the installation more secure.

[0058] Optionally, the guide part 1 is made of elastic material.

[0059] Optionally, the mounting portion 2 is made of a hard material.

[0060] In this embodiment, the guide portion 1 is made of soft rubber and the mounting portion 2 is made of hard rubber, and they are integrally formed through a two-color injection molding process. The elastic material used for the guide portion 1 improves its energy absorption and deformation capacity, preventing damage; the hard material used for the mounting portion 2 ensures a more secure installation.

[0061] Example 2

[0062] This embodiment provides a car, such as Figure 4-5 As shown, including:

[0063] Car body;

[0064] The automobile wheel air deflector in the first embodiment is installed in front of the wheel 31 of the automobile body.

[0065] Specifically, the car's wheel wind deflector can guide the airflow, prevent the airflow from directly impacting the rotating tire, reduce the airflow entering the wheel cavity, and thereby reduce the generation of vortices around the tire, which can effectively reduce the vehicle's wind resistance.

[0066] While various embodiments of the present invention have been described above, the above description is intended to be illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
