Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of automobile parts, and particularly relates to an active air intake grille, an air deflector and a vehicle. BACKGROUND

[0002] With the improvement of economic level, the automobile has become the main tool for people to travel. In order to ensure the normal work of the automobile engine, an active air intake grille (AGS) is usually arranged at the front end of the automobile to enable air to enter the engine compartment and timely take away the heat generated in the engine compartment. The active air intake grille is a mechanism for reducing wind resistance by reducing or even completely closing the grille opening under certain working conditions. Through the integrated active air intake grille control module, the active air intake grille is closed at high vehicle speed and low cooling demand to reduce wind resistance and improve fuel economy or electric vehicle range; the active air intake grille is opened when the cooling demand is large to meet the cooling demand of the automobile cooling module.

[0003] With the development of the automobile industry, especially the rapid development of the electric vehicle industry, the market share of electric vehicles is rapidly increasing, and the range of electric vehicles has become the focus of consumers. However, in the market environment where the battery cost accounts for nearly 40% of the total vehicle cost, blindly increasing the battery capacity to improve the range is neither economical nor practical, so the technical solution of reducing the wind resistance of the automobile to improve the range is pursued by the vehicle manufacturers, and the technical solution of reducing the size of the front grille opening contributes greatly to the reduction of wind resistance.

[0004] In actual application, although reducing the size of the active air intake grille opening has good ability to reduce wind resistance, the air flow entering the cooling module of the automobile will be reduced due to the shielding of the device and the change in size, which will bring great heat dissipation pressure to the cooling module, resulting in poor heat dissipation effect, therefore, it is necessary to solve the contradiction between the wind resistance reduction of the active air intake grille and the heat dissipation of the cooling module. SUMMARY

[0005] The application aims to provide an active air intake grille, an air deflector and a vehicle, which can maximize the front end air intake under the condition of reducing the wind resistance of the automobile, increase the heat exchange efficiency, improve the heat exchange performance of the cooling module, and ensure the safety of the automobile driving.

[0006] To achieve the above technical purpose, the technical solution adopted by the application is as follows:

[0007] The application discloses an active grille, which comprises a plurality of active grille blades arranged in parallel, wherein each active grille blade comprises two symmetrically arranged mounting supports and a blade body arranged between the two mounting supports, a plurality of ribs are arranged on the blade body, and the lower bottom surface of the blade body is streamlined.

[0008] The active grille of the application can destroy the laminar flow state of the airflow passing through the active grille by arranging ribs on the blade body, thereby improving the turbulence of the radiator airflow entering the cooling module of the vehicle and effectively increasing the heat dissipation efficiency.

[0009] Further, the blade body is arranged in an inclined manner.

[0010] Further, mounting holes are arranged on the mounting supports, which facilitates the mounting operation of the active grille.

[0011] In addition, the application further discloses a wind deflector, which comprises an air inlet cavity and a cover body surrounding the air inlet cavity, one end of the cover body is fixedly connected with a front end flow guide structure, the other end is fixedly connected with a rear end cover, the front end flow guide structure is sealingly connected between the front end flow guide structure and the front bumper of the vehicle, the cover body and the rear end cover are sealingly connected with the cooling module of the vehicle, the active grille is fixedly arranged in the air inlet cavity, a rotating connecting piece is arranged in the air inlet cavity, and the blade body is rotatably connected to the rotating connecting piece.

[0012] The wind deflector of the application realizes the opening and closing of the active grille by rotating the blade body through the rotating connecting piece, when cooling is required, the rotating connecting piece drives the active grille to rotate by a corresponding angle, air is introduced into the air inlet cavity from the front end flow guide structure, and then the air is guided into the cooling module of the vehicle through the rear end cover after the laminar flow state of the air is destroyed by the active grille, so that the performance of the radiator can be fully utilized and the heat dissipation efficiency is improved.

[0013] Further, the length of the front end flow guide structure gradually increases in a direction away from the cover body, and the front end flow guide structure has a horn-shaped structure. The arrangement of the front end flow guide structure can effectively increase the air inlet area, thereby improving the air inlet amount.

[0014] Further, the rear end cover has an arc-shaped structure. The arc-shaped structure of the wind deflector ensures the smoothness of the air inlet, can effectively reduce the air inlet resistance, and is further conducive to improving the air inlet amount.

[0015] Further, first mounting flanges are arranged on the two symmetrically arranged sides of the rear end cover, second mounting flanges are arranged on the cover body at the positions connected with the cooling module, and fixing bolts are arranged on the first mounting flanges and the second mounting flanges.

[0016] Furthermore, sealing foam is fixedly installed on the front airflow guide structure at the position corresponding to the front bumper, and sealing foam is also fixedly installed on the cover and rear cover at the position corresponding to the cooling module. The installation of sealing foam ensures the sealing performance between the airflow guide and the front bumper, and between the airflow guide and the cooling module, and can ensure to a certain extent that the incoming airflow can reach the cooling module as much as possible.

[0017] The present invention also discloses a vehicle comprising the aforementioned active grille shutter.

[0018] The present invention also discloses a vehicle that includes the aforementioned air deflector.

[0019] The invention employing the above technical solution has the following advantages:

[0020] 1. An active air intake grille of the present invention, by setting ribs on the blade body to disrupt the laminar flow state of the airflow passing through the active air intake grille, and by setting the structure of the blade body, reduces the intake resistance and improves the heat dissipation efficiency.

[0021] 2. The air guide cover of the present invention has a relatively simple structure. Through the synergistic effect of the front air guide structure, the rear cover and the active air intake grille, the front air intake volume is maximized while reducing the wind resistance of the vehicle, thereby increasing the heat exchange efficiency, improving the heat exchange performance of the cooling module and ensuring the safety of the vehicle.
