Problems solved by technology

This kind of aerodynamic structure design does not recognize the essential characteristics of electric vehicles, resulting in little improvement in the shape resistance, internal circulation resistance, and airflow conditions of the wake area at the rear of the electric vehicle. Range gains are limited, and battery pack cooling is flawed

Embodiment 1

[0036] see figure 1 , in the figure (the direction of the arrow in the figure indicates the flow direction of the gas), the electric vehicle with reduced resistance and increased range of the present invention includes an aerodynamic structure with reduced resistance and increased range. Cabin air flow path section, rear air flow path section.

[0037] The air intake section of the front box of the electric vehicle includes the air intake box 1. The air intake box 1 is an air intake structure improved by the front cabin or the front trunk of the electric vehicle, and is mainly used to enter the gas, including the panels of the front cabin or the front trunk. Each panel and firewall of the air intake box, and air intake holes are opened on the front bumper panel and the front beam to facilitate the air to enter and reduce the windward area. There is a sealing partition 2 inside the box 1, and the sealing partition 2 divides the air intake box 1 into upper and lower boxes, and ...

Embodiment 2

[0048] Present embodiment figure is not drawn. This embodiment is similar in structure to Embodiment 1, and the same structure will not be repeated here. The difference is that the cockpit air flow passage section of this embodiment includes left and right front pillars, left and right upper side beams, left and right rear pillars, and left and right rear wings. The left and right flow passages set inside the plate replace the left and right air ducts I8 along the left and right front pillars, left and right upper beams, left and right rear pillars and left and right air ducts in Embodiment 1; It communicates with the rear pillar 7, the rear pillar 7 and the flow channel in the rear fender, and the flow channel in the rear fender 7 communicates with the flow channel in the bumper.

[0049] The aerodynamic route of the whole car is as follows:

[0050] Air → Radiator → Firewall of the lower box → Left and right front pillars with internal flow channels → Left and right upper s...

Embodiment 3

[0053] Present embodiment figure is not drawn. This embodiment is similar in structure to Embodiment 1, and the same parts of the structure will not be repeated here. The difference is that no sealing partition is provided in the air intake box of this embodiment, and the air intake box 1 is not divided into upper and lower two boxes. The air inner air passage section is two left and right air ducts I8 laid along the left and right front pillars, left and right upper side beams, left and right rear pillars and left and right rear fenders. The mixed hot and cold air in the air intake box 1 is guided from the upper body together. flow.

[0054] The aerodynamic route of the whole car is as follows:

[0055] Air→radiator→firewall of the air intake section→two air ducts Ⅰ8 (laid along the left and right front pillars, left and right upper side beams, left and right rear pillars, and left and right rear fenders respectively)→the internal flow channel of the rear bumper, facing the ...

Abstract

The invention belongs to the technical field of electrical automobiles and particularly relates to an electrical automobile with resistance reduction and distance increasing functions. The electrical automobile comprises an aerodynamic structure with the resistance reduction and distance increasing functions. The aerodynamic structure comprises a front box air inlet section, a cab air passage section and an automobile tail air passage section which are connected in sequence. The front box air inlet section of the electrical automobile comprises an air inlet box. The air inlet box is an air inlet structure composed of all components of a forecabin of an automobile body and a firewall. The firewall is provided with air ventilation holes and / or an air guiding groove. The cab air passage section comprises an internal passage arranged along a left front column, a right front column, a left upper edge beam, a right upper edge beam, a left rear column, a right rear column, a left rear wheel fender and a right rear wheel fender, and / or a hollow air flowing-in channel formed by surfaces of battery packs and partition plates corresponding to the surfaces of the battery packs. The automobile tail air passage tail exhaust section comprises a rear bumper with a passage, and air exhaust holes are formed in the rear bumper surface facing the automobile tail air wake zone. By the adoption of the electrical automobile, the air resistance can be reduced, and the traveling distance can be increased.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, in particular to an electric vehicle with reduced resistance and increased range. Background technique [0002] The air resistance of electric vehicles consumes a lot of energy, but at present, the understanding of the aerodynamic characteristics of electric vehicles is limited at home and abroad, and the design ideas are still very backward. At present, electric vehicles at home and abroad still use air intake to cool the radiator and other systems. Or blown, and then the air is directly discharged from the front box in the aerodynamic structure design of the car body. Even a considerable part of the space in the front box of an electric vehicle is used as a luggage compartment. This kind of aerodynamic structure design does not recognize the essential characteristics of electric vehicles, resulting in little improvement in the shape resistance, internal circulation resistance, and ai...
