Problems solved by technology

Due to the influence of the front grille, pipeline and surrounding components of the vehicle, the fresh air entering from the front of the vehicle is easy to leak, resulting in insufficient air intake for the cooling module; at the same time, the hot air after the temperature rise in the engine room is easy to flow back to the cooling system. module entry
Especially for pure electric vehicles, most of the front-end models adopt the closed design concept of the upper grille, which will greatly reduce the air intake of the front-end cooling module. In addition, due to the deviation of the position of the lower grille and the relative position of the cooling module, the airflow transmission is not good. Smooth, heat exchange efficiency is greatly compromised

Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention according to specific situations.

[0040]In the present in...

Embodiment 1

[0043] Such as figure 1 As shown, a new type of wind deflector structure for pure electric vehicles, including wind deflector main body 1, side wind deflector 2, front bumper attachment 3 and bottom wind deflector 4; the external air in front of the car flows through the middle and lower compartments Behind the grille, after being retracted by the side air deflector 2, it is diverted through the front bumper attachment 3, a part of the gas flows backward along the bottom air deflector 4, and enters the cooling module; the other part of the gas flows upward along the main body of the air deflector 1 , and then into the cooling module;

[0044] The upper end of the air deflector main body 1 is screwed to the upper beam of the front frame, the lower end is screwed to the front frame bracket, the ends of the two side air deflectors 2 are respectively screwed to both sides of the front frame bracket, and the bottom is connected to the bottom air deflector 4 connection; the front e...

Embodiment 2

[0050] Such as figure 1 As shown, this embodiment provides a pure electric vehicle wind deflector structure, including a wind deflector main body 1, two side wind deflectors 2, a front bumper attachment 3 and a bottom wind deflector 4; the wind deflector main body 1 The upper end of the upper end is screwed to the upper beam of the front frame, the lower end is screwed to the front frame bracket, the ends of the two side wind deflectors 2 are respectively screwed to both sides of the front frame bracket, and the bottom is connected to the bottom wind deflector 4; the bottom wind deflector The front end of the air deflector 4 is closely overlapped with the lower edge of the front bumper, and the rear end is screwed to the bottom of the front frame; the front bumper attachment 3 is located between the main body of the air deflector 1 and the bottom air deflector 4, and the front bumper The rear end surface of the attachment 3 is connected with the front frame support, the upper ...

Abstract

The invention discloses an air deflector structure of a pure electric vehicle, which belongs to the technical field of automobile structures and comprises an air deflector main body, two side air deflectors, a front bumper accessory and a bottom air deflector. The air deflector body guides fresh air flowing from the middle grating and the lower grating to flow upwards through the arc face of the air deflector body and enters the cooling module. The side air guide plates gather air from incoming flows on the two sides of the grating, and the air inlet amount is increased. The bottom air guide plate can guide air flowing from the lower grating into the cooling module and can prevent heat from flowing back from the bottom of the cabin. Due to the cambered surface and inclined arrangement of the air deflector main body, the problem that the air inlet amount of a cooling module is low due to the fact that a grid on a pure electric vehicle is closed can be effectively solved; the bottom air guide plate combines the requirements of heat management and pedestrian protection, has the functions of air guide and shank protection, not only prevents idling heat backflow, reduces the air inlet temperature of the condenser, reduces high-speed leakage, reduces wind resistance in a cabin, but also has the function of protecting pedestrian safety.

Description

technical field [0001] The invention belongs to the technical field of automobile structures, and in particular relates to a wind deflector structure of a pure electric vehicle. Background technique [0002] With the increase in cooling requirements for motors and batteries of new energy vehicles, the performance requirements for cooling systems are also getting higher and higher. Due to the influence of the front grille, pipeline and surrounding components of the vehicle, the fresh air entering from the front of the vehicle is easy to leak, resulting in insufficient air intake for the cooling module; at the same time, the hot air after the temperature rise in the engine room is easy to flow back to the cooling system. module entry. Especially for pure electric vehicles, most of the front-end models adopt the closed design concept of the upper grille, which will greatly reduce the air intake of the front-end cooling module. In addition, due to the deviation of the position ...
