Automobile anti-collision air cushion device

Abstract

The invention relates to an automobile anti-collision air cushion device. The automobile anti-collision air cushion device comprises an AT89S51 control module, a laser distance measuring module, an alarm module, a display module, an air cushion module and a power module, wherein the output end of the AT89S51 control module is connected with the input ends of the alarm module, the air cushion module and the display module; the output end of the laser distance measuring module is connected with the input end of the AT89S51 control module; the power module supplies power to the AT89S51 control module, the laser distance measuring module, the alarm module and the display module. The laser distance measuring module is arranged at the foremost position of the head of an automobile; when the laser distance measuring module transmits a detected signal to the AT89S51 control module, the AT89S51 control module processes the signal, and the display module displays current information about the distance between the automobile and an automobile in front of the automobile in real time; when the laser distance measuring module detects that the distance between the automobile and the automobile in front of the automobile is smaller than a preset maximum safety distance, the AT89S51 control module sends an instruction to the alarm module, and the alarm module gives a sound-light alarm in cooperation with the display module.

Description

technical field [0001] The invention relates to an anti-collision air cushion device for automobiles, in particular to an air cushion device capable of effectively preventing rear-end collision accidents of automobiles on expressways. Background technique [0002] With the development of society, the number of cars is increasing year by year, and the popularity of cars has changed people's production, life and way of thinking. While promoting the material and spiritual civilization of the society, it also bears the burden of traffic accidents. pain of. All over the world, on highways, car rear-end collision accidents often occur, and even serial rear-end collisions occur, ranging from a few dozen vehicles to as many as dozens of vehicles colliding together, which is terrible. In the whole road traffic accidents, automobile rear-end collision accidents account for more than 70%. Some large fatal traffic accidents may be caused by a small rear-end collision at the beginning. ...

AI Technical Summary

Problems solved by technology

[0006] The present invention mainly solves the problem that the anti-collision device in the prior art does not have the pre-alarm reminder function, or the alarm function is limited by many factors due to high speed, and provides an automobile anti-collision air cushion device, which can turn the vehicle The distance between the vehicle in front or the obstacle is displayed in real time. When the distance is less than the preset maximum safety distance, the driver will be notified in time to avoid danger. When the driver fails to avoid danger in time and a rear-end collision occurs, the strip air cushion Buffer function, to a certain extent, protect the personal and property safety of users
