Description
Technical field
The present invention relates to electric automobile, particularly relate to a kind of electric automobile with preferably sealing effectiveness and sealing member thereof.
Background technology
Electric automobile refers to vehicle power for power, travels with motor-driven vehicle, meets the vehicle of road traffic, security legislation requirements. Owing to electric automobile uses electric energy little relative to the orthodox car environmental pollution using Fuel Petroleum, thus the prospect of electric automobile is extensively had an optimistic view of. But the manufacturing technology of electric automobile currently on the market is ripe not enough, the problem still suffering from each side in the manufacture process of electric automobile.
Electric automobile is typically provided with underbody, is installed below battery at underbody and provides the energy for electric automobile. Battery has a collecting shell, houses shell and defines a host cavity, and multiple battery modules are contained in host cavity. When battery-powered operation, battery modules temperature can raise and need cooling device to cool down battery modules to guarantee battery normal operation at a normal temperature. Existing cooling device has the air conditioner cooling system and fan that are arranged on interior of body, underbody offers through hole, battery is arranged on the lower section of underbody through hole, cooling system refrigeration reduces after air themperature, and the air of cooling can be blowed to by the through hole of underbody and be assembled in battery container intracavity below underbody to cool down its interior battery modules by fan.
Refer to Fig. 1 and show the part-structure of existing a kind of electric automobile. This electric automobile includes a underbody 10, is arranged at the cooling device 20 above underbody 10 and is arranged at the battery 30 below underbody 10. Described underbody 10 is formed a through hole 11, for cooling device 20 cold wind or cold air is inputted in the host cavity of battery 30, thus battery 30 is carried out cooling process, in case battery 30 use for a long time overheated and damaged. When set of cells is contained on vehicle body, a small?gap suture 50 between described underbody 10 and battery 30, would generally be had because of mechanical engagement, thus cooling device 20 is input to the cold wind in battery 30 and can part run away from gap 50. For preventing the loss of cold wind or cold air, described electric automobile also includes a sealing member 40 being arranged at this gap 50 place.Generally this kind of sealing member 40 is clamped between underbody 10 and battery 30 to prevent cold wind to run off in annular. This kind of sealing member 40 has the main part 41 being vertically arranged between underbody 10 and battery 30. At cooling device 20 in the process of transporting cold wind in battery 30 or cold air, the inwall of the main part 41 of sealing member 40 can be produced certain pressure by air-flow or cold wind, when pressure is excessive or sealing member after a long time use, sealing member 40 can loosen and depart from underbody 10 or battery 30, so that sealing effectiveness is deteriorated, in turn result in the loss of cold wind or cold air.
Therefore, it is necessary to provide the electric automobile of a kind of improvement and sealing member thereof to solve the problems referred to above.
