A Self-adjusting Ultrasonic Detector for Anti-Side Collision of Automobiles

Abstract

The invention discloses a self-adjusting type automobile side collision prevention ultrasonic detector. The self-adjusting type automobile side collision prevention ultrasonic detector comprises an automobile, an air pressure mechanism is arranged on the right side of the automobile, the air pressure mechanism comprises a storage box, an air pressure cavity with an upward opening is formed in thestorage box, an air pressure plate is arranged in the air pressure cavity in a sliding manner, the air pressure plate can slide up and down according to external atmospheric pressure, and a transmission mechanism is arranged on the front side of the automobile. According to the detector, the speed of the automobile is determined by turbulent flow generated at the rear part of the automobile in theautomobile driving process to determine whether an ultrasonic ranging part device on the side of the automobile needs to be started or not, utilize useless turbulent flow and save energy; and moreover, along with increase of the turbulent flow on the rear portion of the automobile, the ultrasonic ranging alarm part can start alarm prompt at a far position, a good side collision prevention effectis achieved, and under the condition that the automobile speed is higher, the alarm distance is longer, and the situation that a driver cannot respond well due to the fact that the automobile speed istoo high is avoided.

Description

technical field [0001] The invention relates to the related field of ultrasonic equipment, in particular to a self-adjusting ultrasonic detector for side collision prevention of automobiles. Background technique [0002] Due to the strong directivity of ultrasonic waves, slow energy consumption, and long distances in the medium, ultrasonic waves are often used to measure distances. In automobiles, multiple ultrasonic instruments are usually used to form a car’s reversing reminder to prevent collisions at the rear of the car. , Ultrasonic instruments are also used for collisions on the side of the car, and the existing ultrasonic instruments on the side of the car are only for simple distance measurement. When the fixed distance is reached, an alarm will be issued. When the speed is slow, the driver can better control the distance between the car and the side objects, and there is no need to use an ultrasonic prompting device. Unable to make timely adjustments.
