Brake safety protection device for emergency braking of vehicle

Abstract

The invention discloses a vehicle emergency braking safety protection device which comprises a speed reduction device installed at the tail of a vehicle and a control console arranged in a vehicle cab, and a control module is arranged in the control console and used for controlling the speed reduction device and the control console under the vehicle emergency braking condition. And the speed reducing device is automatically triggered or manually started and controlled to decelerate the vehicle. By the adoption of the structure, the defect that traffic accidents are prone to being caused due to the fact that the braking distance of an existing vehicle is too long during emergency braking is overcome, the speed reduction device which is automatically started or manually triggered is additionally arranged at the tail of the vehicle, the speed reduction device is unfolded during emergency braking, and the resistance of the vehicle is greatly increased; and the sliding distance generated by inertia and power is prevented, so that the braking distance is reduced, the tire burst condition under the emergency braking condition is reduced, vehicle rear-end collision and other traffic accidents are effectively prevented, and the occurrence probability of the traffic accidents is reduced.

Description

technical field [0001] The invention belongs to the technical field of vehicle safety accessories, and in particular relates to a vehicle emergency braking safety protection device. Background technique [0002] At present, the emergency braking of most vehicles forces the vehicle to stop after dragging for a certain distance through the friction force generated on the limited contact area between the wheels and the ground. There is a time difference between when the brake pedal is pressed and the wheels stop completely (for example, Jiefang brand trucks, the time difference is about 1.6 seconds). In this way, the result of the above two reasons is that the braking response is slow and the braking distance is long. Sometimes due to problems such as road conditions or brake adjustment, there will be "deviation" phenomenon, which often leads to accidents. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a vehicle e...
