[0025] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1-Figure 2As shown, the utility model provides a vehicle body side panel assembly 1, including a side panel body 12 and an air guide plate 14. The side panel body 12 is provided with a wheel mounting opening 13 for mounting the rear wheel 3 of the vehicle; the air guide plate 14 is connected to the side panel body 12 and is located in front of the rear wheel mounting opening 13 of the vehicle. An air duct 2 is formed between the air guide plate 14 and the side panel body 12. The air duct 2 is used to guide at least part of the airflow outside the side panel body 12 to the rear wheel mounting opening 13. The air guide plate 14 can introduce the airflow of the side panel body 12 into the air duct 2, and flow out from the front side of the rear wheel 3 to dissipate heat for the rear wheel 3. In the embodiment of the present application, the air guide plate 14 is used to surround the air outlet duct 2. The shape of the air guide plate 14 is approximately long and strip-shaped. The air duct 2 is a contraction-type channel along the length direction of the vehicle. The material and size of the air guide plate 14 are not limited. The air guide plate 14 can be made of any solid material, for example, carbon fiber, reinforced plastic or aluminum alloy commonly used in vehicles.

[0027] In some optional embodiments, the air duct 2 includes an air inlet 22 located outside the side panel body 12, and the air inlet 22 is triangular or square. The air inlet 22 is triangular in shape because an approximately triangular air inlet is formed between the side panel body 12 and the air guide plate 14. It can be understood that the air inlet 22 is triangular in shape, which can provide a larger ventilation volume while meeting the vehicle body shape and the internal passenger compartment space.

[0028] In some optional embodiments, the air duct 2 includes an air outlet 24, and the air outlet 24 is strip-shaped. The air outlet 24 is formed inwardly of the side plate body 12 and the air guide plate 14 to form a strip-shaped air outlet 24. The air outlet 24 is arranged in a strip shape to increase the flushing area of ​​the airflow to the rear wheel 3, and the airflow will not form a vortex when flushing, thereby improving the airflow flushing and heat dissipation effect on the rear wheel 3.

[0029] In some preferred embodiments, the air outlet 24 of the air duct 2 is smaller than the air inlet 22 of the air duct 2. It is understandable that the air duct 2 is formed between the air inlet 22 and the air outlet 24 for air flow to pass through, and the speed of air flow passing through the air duct 2 is closely related to the size of the air outlet. Normally, the air inlet should be larger than the air outlet, which can reduce the wind pressure in the air duct, thereby making the ventilation and heat dissipation more stable. If the air inlet in the ventilation duct is smaller than the air outlet, the wind pressure will increase, making the ventilation effect unstable. In order to ensure the ventilation and heat dissipation effect of the ventilation duct, the air inlet of the ventilation duct should be larger than the air outlet to reduce the wind pressure, and the ventilation duct must be backward along the direction of air flow. In summary, the relationship between the size of the air inlet and the air outlet of the ventilation duct has a great influence on the size of the wind pressure, and the size relationship between the air inlet and the air outlet can be reasonably designed and adjusted according to the actual heat dissipation requirements.

[0030] In some preferred embodiments, the cross-sectional area of ​​the air duct 2 gradually decreases from the air inlet 22 to the air outlet 24. In the present application, the size of the air duct 2 shows a shrinking trend from one end of the air inlet 22 to the other end of the air outlet 24. According to the principle of conservation of mass, the airflow will be further accelerated in the air duct 2 to form a high-speed airflow, and finally flow out from the outlet. The airflow gradually decreases through the air inlet 22 of the air duct 2 connected to the front cavity of the rear wheel 3. The gradual reduction in the diameter of the air duct 2 can increase the flow rate of the airflow when the airflow passes through the air duct 2, and can maintain a fast and stable heat dissipation effect on the rear wheel 3.

[0031] In some optional embodiments, the air guide plate 14 includes a connected air inlet section 21 and an air outlet section 23, the air inlet section 21 is arranged near the air inlet 22 of the air duct 2, and the air outlet section 23 is arranged near the air outlet 24 of the air duct 2. The air outlet section 23 is inclined toward the outer side of the side panel body 12 along the forward direction of the vehicle at the air outlet 24 of the air duct 2 to guide the airflow flowing through the air duct 2 to flow out toward the outer side of the wheel.

[0032] In the present application, the air guide plate 14 and the vehicle body side panel body 12 form an air duct 2, the air inlet section 21 of the air duct 2 is connected to the outside air through the air inlet 22, and the air outlet 24 at the other end of the air duct 2 is connected to the front cavity of the rear tire.

[0033] In the present application, the air outlet section 23 of the air duct 2 is bent outward near the air outlet 24, and the air duct 2 is directed obliquely to the rear of the rear wheel 3. The high-speed airflow directed obliquely to the rear passes through the outside of the rear wheel, and the low-pressure area formed by the high-speed airflow outside the rear wheel 3 sucks out the airflow inside the rim, greatly increasing the airflow flow through the rear rim, greatly reducing the temperature inside the wheel, and improving the heat dissipation capacity of the brake system. At the same time, the high-speed airflow outside the rear wheel 3 is conducive to combing the turbulence outside the rear wheel 3, achieving the effect of drag reduction. It can be understood that the air outlet 24 is connected to the side panel body 12 and is located in front of the rear wheel 3. The air outlet 24 at the side door panel of the vehicle body flushes the fast-flowing airflow from the outside of the rear wheel of the vehicle, and uses the negative pressure of the high-speed airflow to suck out the turbulence in the rear wheel cavity of the vehicle, reducing wind resistance and improving heat dissipation efficiency.

[0034] In some optional embodiments, the air deflector 14 is located at the lower side of the rear fender 4 of the vehicle, and the air deflector 14 is installed on the outer side of the body side panel main body 12. The body side panel main body 12 is connected to the rear fender 4. This position is suitable for arranging the air deflector 14 and the rear wheel 3 at the same height, which is beneficial for the high-speed flowing gas to flow quickly to the rear wheel 3 after being discharged from the air outlet. The height at which the air deflector 14 is set relative to the rear wheel 3 is related to the heat dissipation effect. If the air deflector 14 is set too high or too low relative to the rear wheel 3, it is not conducive to the heat dissipation of the rear wheel 3.

[0035] In some optional embodiments, the surface of the air guide plate 14 is provided with guide ribs 15, which are located in the air duct 2 and are used to guide the airflow inside the air duct 2 to the air outlet 24 of the air duct 2. The guide ribs 15 help to guide the airflow inside the air duct 2 along the direction of the vehicle body, prevent the formation of vortices in the air duct 2 that can be guided, and at the same time, the guide ribs 15 help to improve the structural strength of the air guide plate 14.

[0036] Optionally, the guide ribs 15 provided on the air guide plate 14 can be lengthened to form guide fins 16 for further increasing downforce and enhancing the stability of the car; the guide winglet is arranged in the air duct 2 and connected to the air guide plate 14, the guide winglet 16 has a pressure surface and a suction surface, the pressure surface is arranged close to the top wall of the air duct 2, and the suction surface is arranged away from the top wall of the air duct 2, so as to separate at least part of the air duct 2 into a first flow channel and a second flow channel distributed up and down along the height direction of the vehicle; the guide winglet also has a leading edge and a trailing edge, the leading edge is arranged close to the air inlet 22, and the trailing edge is arranged close to the air outlet 24, which not only reduces the aerodynamic noise of the vehicle, but also improves the stability of the vehicle during driving, and also accelerates the heat dissipation of the vehicle's braking structure.

[0037] It can be understood that the air duct 2 in the present application includes an air inlet section 21 and an air outlet section 23 that are interconnected. The air inlet section 21 is connected to the side body plate main body 2, and the air outlet section 23 is located at the front end of the rear wheel 3. The guide vane 16 is arranged in the air inlet section 21 to separate the air inlet section 21 into a first flow channel and a second flow channel distributed up and down along the height direction of the vehicle. Based on the above embodiment, the air inlet section 21 is located in front of the air outlet section 23 along the length direction of the vehicle, and the guide vane 16 separates the air inlet section 21 and the air outlet section 23 into a first flow channel and a second flow channel. Therefore, the guide vane 16 will generate a suction surface in the air outlet section 23 and the air inlet section 21, which helps to improve the downward stability of the vehicle. The guide vane 16 can arbitrarily adjust the angle between the chord of any airfoil of the guide vane 16 and the length direction of the vehicle according to the balance stability and heat dissipation requirements in actual implementation, so as to achieve the best balance stability and heat dissipation effect.

[0038] In the present application, the air inlet 22 is arranged along the length direction of the air inlet section 21, and the air outlet 24 is arranged along the length direction of the air outlet section 23. The above arrangement allows the air inlet 22 arranged on the air inlet section 21 and the air outlet 24 arranged on the air outlet section 23 to have a larger layout space in the width direction of the car, thereby making the area of ​​the air inlet larger and making the air guiding and heat dissipation effect of the vehicle body side panel assembly 1 better.

[0039] The utility model also provides a vehicle body, including a vehicle body side panel assembly 1, on which a rear wheel 3 can be installed. In this embodiment, the vehicle body is applied to the vehicle and can also effectively reduce excessive energy consumption of the vehicle during high-speed driving, reduce wind resistance during high-speed driving, and dissipate heat from the rear wheel caused by extreme emergency braking.

[0040] The utility model also provides a vehicle, including a vehicle body side panel assembly 1 or including the above-mentioned vehicle body, and the vehicle also includes a rear wheel 3, and the rear wheel 3 is arranged at a wheel mounting opening 13. Specifically, in this embodiment, since the wind deflector 14 arranged on the vehicle body of the above-mentioned structure has the advantage of good flow diversion effect, the vehicle adopts the vehicle body of the above-mentioned structure, which can effectively reduce the excessive energy consumed by the vehicle during high-speed driving and the wind resistance of the rear end, and dissipate heat to the rear wheel during emergency braking. Therefore, the vehicle provided by this embodiment has the advantages of low energy consumption, small wind resistance, and good heat dissipation of the braking system.

For ordinary technicians in the relevant field, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the utility model.
