Description

Technical Field

[0001] The utility model relates to the technical field of rear enclosures, in particular to a rear enclosure for an automobile with a diffusion structure. Background Art

[0002] The rear bumper installed at the rear of the car not only has a decorative function, but more importantly, it is a safety device that absorbs and mitigates external impact, protects the car body and the safety of the passengers. From a safety perspective, it can play a buffering role in the event of a low-speed collision, protecting the rear of the car body; it can also play a certain role in protecting pedestrians in the event of an accident with pedestrians. From an appearance perspective, it is decorative and has become an important component for decorating the appearance of a car; at the same time, the rear bumper of a car also has a certain aerodynamic effect.

[0003] In order to further improve the aerodynamic performance of the rear apron of the car, the existing rear apron of the car is usually provided with a rear diffuser. The rear diffuser is to add a deflector to the rear of the car to comb the airflow at the bottom of the car so that the airflow can pass through the bottom of the car quickly. The air flow rate of the upper part of the vehicle is made smaller than that of the lower part, thereby achieving the purpose of increasing the downforce of the car and improving stability. Moreover, compared with the rear wing, the rear diffuser does not generate additional resistance. However, the existing rear apron of the car with a rear diffuser only guides the airflow at the rear of the car through the deflector, which has a high limitation on the speed-up effect of the airflow under the car, and has limited effect on helping the car to generate downforce.

Specifically, the diffusion structure 2 comprises a plurality of guide plates 21, the plurality of guide plates 21 are arranged along the length extension direction of the surround body 1, and the plurality of guide plates 21 are parallel to each other, so that an airflow channel is formed between the two guide plates 21. In practical applications, the rear surround of an automobile with a diffusion structure 2 is installed to the rear of an automobile, when the vehicle is driving, the airflow at the bottom of the vehicle is guided by the plurality of guide plates 21, so as to guide the airflow at the bottom of the vehicle to flow out quickly at the rear of the vehicle, and then effectively improve the gas flow rate at the bottom of the rear of the vehicle, so that the gas flow rate at the top of the rear of the vehicle is less than the gas flow rate at the bottom, thereby increasing the downforce at the rear of the automobile, so as to improve the tire grip and driving stability during the driving process of the vehicle.

When the bottom and side of the rear enclosure come into contact with a larger contact surface, the protrusion 123 can preferentially come into contact with the contact surface. By strengthening the structural strength of the protrusion 123, such as adding reinforcing ribs 120 on the surface of the protrusion 123, the bottom and lateral collision resistance of the second enclosure unit 12 can be effectively improved.
