Technical Field
Relate to vehicle technical field, especially relate to the vehicle that the rear of a vehicle can be outstanding backward.
Background
The energy consumption of the vehicle is used to overcome the resistance, the greatest of which in high-speed driving comes from the air resistance, i.e. the wind resistance. The function consumption caused by wind resistance is more than 60% of the total energy consumption when the vehicle speed is 80 km/h, and the higher the vehicle speed is, the larger the wind resistance consumption is. The external wind resistance accounts for about 60% of all wind resistances, and a negative pressure region at the tail of the vehicle body is an important source of the wind resistance; in particular, in 2-box cars, MPV/SUV models, buses, trucks, container vehicles, van vehicles, and the like, in order to ensure a sufficient vehicle space, the vehicle body rear portion is generally in a vertical shape or a shape close to the vertical shape, so that the wind resistance caused by the negative pressure generated from the vehicle body rear portion during high-speed traveling is considerably large. The wind resistance coefficient of a common three-compartment car is between 0.2 and 0.3, the wind resistance coefficient of an MPV/SUV car is about 0.3 to 0.5, and the large difference of the wind resistance coefficients is mainly caused by the modeling difference of the car tail. The wind resistance has a great influence on the endurance of the electric automobile, and particularly the electric automobile needs to reduce the wind resistance, so that the electric automobile is influenced by the wind resistance, and few manufacturers release pure electric multi-voltage vehicle (MPV) at present because the endurance cannot meet the requirement of a user. The existing wind resistance reducing technology is used for improving the appearance of the vehicle head and the vehicle tail or increasing some turbulence measures, so that the wind resistance of the vehicle type cannot be greatly reduced.
