A kind of protective plate structure of automobile rear protection

Abstract

The invention provides a lower protection plate structure of an automotive rear bumper, and the lower protection plate structure is applied to the technical field of automotive body components and parts. A lower protection plate body (1) of the lower protection plate structure is connected with an automobile bottom (3) through an adjusting component (2). A motor (5) is mounted in a motor box (4) of the adjusting component (2). A rotating shaft of the motor (5) is connected with one end of a linkage rod (6) fixedly. The other end of the linkage rod (6) is hinged with the lower protection platebody (1). The motor (5) is connected with a control component capable of controlling start and stop as well as rotation direction of the motor (5). A body front end (8) of the lower protection plate body (1) is arranged at a lower end position close to the automotive rear bumper (9). The lower protection plate structure has the advantages that the structure is simple; through the movable lower protection plate of the rear bumper, air flows at the bottom of an automobile can be guided to positions away from an automobile body, so that the distance between tailing vortexes and the back of the automobile body is increased, pressure on the back of the automobile is also increased, and air resistance of the automobile is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile body parts, and more specifically relates to an automobile rear protection lower protection plate structure. Background technique [0002] With the development of the automobile industry, the governments of various countries and major automobile manufacturers are paying more and more attention to the energy and pollution problems brought by automobiles. In addition to developing new energy sources to replace traditional energy sources, various technologies and devices to reduce the wind resistance of automobiles at high speeds are constantly being developed. to develop. When the car is running at high speed, the high-speed airflow passes through the front of the car, to the bonnet, the front fender, to the front windshield, the roof, the doors on both sides, the bottom of the car body, and finally to the rear area of ​​the car body. Due to structural requirements, the incoming flow flowing thr...

AI Technical Summary

Problems solved by technology

According to relevant data, for a car with Cd*A=0.8㎡, when the speed reaches 65 kilometers per hour, 55% of the energy output by its power system is used to overcome air resistance, and when the speed reaches 120 kilometers per hour, this A proportion has reached more than 75%, which seriously affects the performance of the vehicle
