Background technique

The Formula Student Contest was originally a formula car competition for college students initiated by the Society of Automotive Engineers, which stipulates that a racing car with good acceleration, braking, handling and durability should be manufactured within one year. The engine compartment in a racing car is used to house the engine and is responsible for transmitting forces, moments and vibrations between the engine and the wheels.

There are some deficiencies in the existing engine compartment, which are specifically manifested in: ①The engine compartment cannot be well installed with the engine, and when the engine is running, the whole racing car vibrates very strongly and the noise is also very loud, which cannot play a good role. The attenuation comes from the effect of the engine's alternating excitation; ②The engine compartment is easily deformed during the collision process, which affects the normal operation of the engine; ③The engine compartment is relatively heavy, and the lightweight design is insufficient. In order to improve the comprehensive performance of the Formula Student racing car during the competition, it is very important to design a new type of engine compartment.

Support leg 1 and support leg 2 are welded to the anti-collision bar on the side of the engine compartment and support leg 3 is welded to the anti-collision bar on the side of the engine compartment for fixing. The upper fixing bar of the engine is welded by three sections of steel pipes. The fixed rod and the lower fixed rod of the engine are all fixed by welding on the support rod at the back of the engine compartment; The rear anti-collision bar is composed of the anti-collision bar on the side of the engine compartment and the lower anti-collision bar on the side of the engine compartment are welded by two sections of steel pipes. The anti-collision bar behind the engine compartment is welded by three sections of steel pipes, and the anti-collision bar behind the engine compartment is fixed by welding on the fixing bar under the engine; The supporting part of the engine compartment is composed of the side support bars of the engine compartment, the inclined support bars of the engine compartment and the support bars behind the engine compartment. The crash bar and the lower anti-collision bar on the side of the engine compartment are fixed. The inclined support bar on the side of the engine compartment is welded by two sections of inclined steel pipes. The inclined support bar on the side of the engine compartment is welded to the anti-collision bar on the side of the engine compartment and the engine It is fixed on the lower anti-collision bar on the side of the cabin.

The entire engine compartment is welded by steel pipes with different or the same diameter and wall thickness, and the structures on the left and right sides are mutually symmetrical.

The utility model has the following characteristics:

(1) The utility model can realize multi-point fixed links of the engine, and the installation of the engine is more stable.

(2) The pipe diameter and wall thickness of each steel pipe of the utility model have been lightweight designed, and the engine compartment is lighter.

(3) Many anti-collision structures are designed in the engine compartment of the utility model, which has high rigidity, is not easy to deform, and is safer.

(4) The structure of the engine compartment of the utility model is more compact, saving space, reducing weight, and making the racing car more portable and flexible.
