Drag plate assembly for vehicle deceleration

Abstract

The invention relates to the technical field of car auxiliary brake and provides a resistance plate assembly for car deceleration. The resistance plate assembly for car deceleration comprises a guard board, bearing pedestals, a resistance plate, a deceleration driving device and a control unit. The guard board is provided with two opposite mounting holes. The guard board is fixedly connected with a base plate of a car body of a car. The bearing pedestals are fixedly arranged in the two mounting holes. The resistance plate comprises a plate body and two mounting bases. The plate body is located below the guard board. The two mounting bases are fixedly arranged at the two ends of the edge of the plate body. The mounting bases are movably connected with bearing holes of the bearing pedestals. The deceleration driving device is arranged between the two mounting holes. The deceleration driving device comprises a supporting frame, a servo motor, a driving output rod and a speed reduction mechanism. A brake information input end and a driving signal output end of the control unit are connected with a brake information sensor and the servo motor respectively. The resistance plate assembly for car deceleration is simple in structure, convenient to use, safe, reliable, capable of increasing wind resistance in the braking process and enhancing the brake effect and little in influence on rigidity performance and strength performance of the car body.

Description

technical field [0001] The invention relates to the technical field of automobile auxiliary braking, in particular to a resistance plate assembly used for automobile deceleration. Background technique [0002] Wind resistance is an important factor affecting the speed of a car. People have always regarded wind resistance as an unfavorable factor, and the research on automobile structure focuses on how to reduce the adverse influence of wind resistance in the process of driving, so as to increase the driving speed of the automobile and reduce the overall energy consumption of the automobile. However, when the car needs to perform emergency braking during high-speed driving, the wind resistance is used to perform auxiliary braking to reduce the speed of the car and shorten the braking distance of the car to the greatest extent. [0003] At present, a groove is generally arranged on the automobile door panel, and a movable deceleration resistance plate is provided in the groov...

AI Technical Summary

Problems solved by technology

On crowded roads, this structure may rub against vehicles driving side by side, and even cause traffic accidents, which poses a certain safety hazard

Moreover, installing the deceleration resistance plate on the door panel of the vehicle body also destroys the structure of the door panel of the car, reducing the rigidity and strength performance of the door panel of the vehicle body
