[0073] A vehicle body assembly comprises the low wind resistance front bumper assembly.

[0074] specific:

[0075] The present invention discloses a low wind resistance front guard assembly, which is characterized in that it comprises a front guard body 1, wherein the front guard body 1 comprises an upper guard body 11 and a lower guard body 12 connected to the upper guard body 11; the upper guard body 11 and the lower guard body 12 adopt a split design; and the front guard body 1 is provided with a guide structure for reducing wind resistance.

[0076] The air guide structure disclosed in the present invention can reduce the wind resistance of the front fender assembly, so that the vehicle using the front fender assembly has lower running wind resistance.

[0077] In addition, the front bumper assembly disclosed in the present invention can reduce wind resistance and thus reduce the energy consumption of the entire vehicle; it is particularly suitable for use in electric vehicles.

[0078] In the present invention, an air duct mechanism 2 is respectively arranged on the opposite sides of the upper guard body 11 in the front guard body 1, and the air duct mechanism 2 includes an air duct opening 224 arranged on the front guard body 1, and the air duct opening 224 is connected to an air duct air curtain; the air duct air curtain includes an air curtain body 221, and the air curtain body 221 is provided with an air flow channel; a sealing strip is arranged at the connection between the air curtain inner plate 222 and the air curtain outer plate 223 to ensure the sealing of the connection between the air curtain inner plate 222 and the air curtain outer plate 223.

[0079] In the present invention, the air duct air curtain comprises an air curtain body 221; the air curtain body 221 comprises an air curtain inner plate 222 and an air curtain outer plate 223, the air curtain inner plate 222 and the air curtain outer plate 223 are arranged opposite to each other, and in the present invention, the air curtain inner plate 222 and the air curtain outer plate 223 are both in a U-shaped structure, such a configuration provides a notch on the air curtain body, and the notch can be used to avoid structures such as radars;

[0080] At the same time, the air curtain body 221 is composed of open air ducts at both ends. The air curtain is essentially composed of two inner and outer plates. After assembly, it is a tubular structure. Due to the need to avoid radar and other structures, the front end of this tubular structure is an air inlet and the rear end is divided into two air outlets. This air duct runs through the front and back, and the front airflow enters from the air inlet and blows out from the two air outlets at the rear, indirectly reducing the overall windward area of ​​the front bumper.

[0081] In addition, in the present invention, an air-permeable grille 13 is provided on the lower protective body 12. The air-permeable grille 13 is essentially an open structure. While it is necessary to dissipate heat for the internal structure, it is also necessary to consider reducing the airflow entering the front cabin. Therefore, a set of active air intake grille components is used at the rear of this opening structure. This air-permeable grille 13 cooperates with the control logic according to the operating conditions of the vehicle. When heat dissipation is required, the blades in the active air intake grille component are partially or fully opened to play a heat dissipation role. When heat dissipation is not required, the blades in the active air intake grille component are closed, which greatly reduces the airflow entering the front cabin, reduces the turbulent state of the airflow in the front cabin, and can reduce wind resistance.

[0082] In addition, the guide structure in the present invention also includes a spoiler component, which includes two spoiler mechanisms 3 spaced apart on both sides of the front guard body 1; each of the spoiler mechanisms 3 includes a spoiler plate; spoiler plates are used on both sides of the lower part of the front guard body 1. When there are no spoiler plates, the airflow separates when passing through the two sides of the lower part of the spoiler plate, causing a turbulent state and increasing wind resistance.

[0083] The spoiler component disclosed in the present invention mainly includes an inner spoiler plate 32 and an outer spoiler plate 31. The inner spoiler plate 32 is embedded in the outer spoiler plate 31. In addition, the spoiler component is connected to the lower edge of the front guard body 1 through the outer spoiler plate 31. In addition, in the present invention, the tail of the spoiler component is in an upright state, and the tail of the spoiler component and the outer side surface of the front guard body 1 are arranged in parallel, so that a U-shaped cavity is formed between the spoiler component and the front guard body 1, and the airflow can pass through the U-shaped cavity. After the airflow passes through, the separation phenomenon is reduced, which can improve the turbulent state of the airflow on both sides of the front guard body 1.

[0084] A lower guard plate 5 is provided at the lower end of the front guard body 1, and air choke boxes 4 are added on both sides of the lower guard plate 5. The air choke box 4 is triangular and is in an inverted slope state after installation. When the airflow passes through the air choke box 4, it is first guided by the slope to the lower part of the air choke box 4, and then passes through the lower part to blow onto the tire, which can effectively improve the turbulent state of the airflow passing through the tire.

[0085] The front bumper assembly disclosed in the present invention can reduce the wind resistance of the whole vehicle by optimizing the parts structure, thereby reducing the energy consumption of the whole vehicle and increasing the cruising range of the whole vehicle.

[0086] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
