Description
Technical Field
The invention relates to a double-layer spoiler.
Background
Because the vehicle body is an irregular streamline body, the vehicle separates air, the air flows around the vehicle, and after the air flows through the roof, the air starts to flow downwards, and the flow speed of the air flow is determined according to the shape of the vehicle tail, for example, the vehicle tail is more attractive, so that the shape of many vehicle tails is steeper, the air flow speed is faster, the effect like a wing is formed, the upward lift force is obtained, and the spoiler acts to reduce the lift force born by the vehicle in running on the premise of not increasing the weight of the vehicle body. The specific reason is that: the side view of an automobile is similar to a wing, and its side view is asymmetric up and down, with a flatter bottom and a curved top. It also separates the flow of air from the front of the vehicle during high speed movement, one part flowing over the vehicle body and the other part flowing under it, which also makes it in the same situation as a wing, resulting in different speeds of air flow over and under the vehicle body, i.e. a higher flow rate over than under, resulting in a higher pressure upwards than downwards. The pressure difference between the two can form a lifting force, so that the automobile is stressed like a wing when moving at a high speed and is stressed upwards, and the lifting force is larger as the automobile speed is larger according to a Bernoulli equation, so that the ground grabbing force (namely the pressure of the automobile to the ground) of the automobile is reduced. In extreme cases, such as where the speed is extremely high, it is entirely possible to have the lift greater than the weight of the vehicle body, which can lead to the vehicle body being lifted off the ground, resulting in the engine idling, wasting fuel, and sometimes even presenting a hazard, especially at cornering. If this happens, the situation that the automobile does centrifugal motion can occur, and the accident of turning over the automobile can be caused. To avoid this, it is thought why an "anti-wing" cannot be mounted on the vehicle, so that a downward force F is created that opposes the wing lift. The inverted wing is characterized in that the top part is flat, the bottom part is bent, the upper air flow speed is lower than the lower air flow speed in high-speed air flow, the upper air pressure is higher than the lower air pressure, and downward pressure is formed, so that the lifting force generated by the movement of the car body can be offset, and the inverted wing is the aerodynamic principle of a tail fin (spoiler).
On the one hand, the spoiler increases the dynamic sense of the appearance of the car; on the other hand, the air resistance generated by the vehicle during high-speed running is effectively reduced, so that the fuel is saved, and meanwhile, the running stability of the vehicle is improved.
At present, two types of conventional blow molding guide plates are on the right: one is that only the deflector is sprayed with the car body in the same color, and no decorative parts are arranged. The other is that the baffle plates are sprayed on the same color of the car body and then are provided with a highlight black decorative plate.
