Pedestrian protection system in the front lower part of muck truck

Abstract

The invention provides a muck truck front underrun pedestrian protective system which comprises a collision sensor, an electronic control system, a gas generator, a pneumatic actuator and a movement mechanism, wherein the crash sensor is used for detecting collision, generating a collision signal, and sending the collision signal to the electronic control system; the electronic control system is used for analyzing the collision signal, judging whether a frontal car-pedestrian collision accident occurs or not, and sending an activating signal to the gas generator if the fact that the accident occurs is judged; an explosive material is arranged in the gas generator, and the gas generator is used for triggering the explosive material to explode to generate gases according to the activating signal; the pneumatic actuator is used for actuating the movement mechanism to open through the gases, so as to enable an FUPD (front underrun protective device) beam of the movement mechanism to move to the front underrun part of the slag car. According to the muck truck front underrun pedestrian protective system, a collided non-motor vehicle driver or pedestrians can be protected during the frontal car-pedestrian collision accident, and the structure form of the movement mechanism can meet the performance requirements during collision.

Description

technical field [0001] The invention relates to an automobile passive safety system, in particular to a pedestrian protection system at the front and lower part of a muck truck. Background technique [0002] In recent years, accidents of muck trucks colliding with people have occurred frequently in domestic urban areas, causing serious casualties and bringing extremely bad social impact. A main type of muck truck collision accident is: the front of the muck truck collides with a non-motor vehicle or a pedestrian, causing the driver of a non-motor vehicle or pedestrian to enter the front lower part of the front of the car after being knocked down, and then run over by the front wheels. Most of the accidents are caused by the speeding of the muck truck or a party running a red light. [0003] There are three main reasons for the frequent occurrence of muck truck collision accidents: [0004] 1. The traffic environment in domestic urban areas is mixed with commercial vehicles...

Problems solved by technology

[0005] 2. The traffic safety awareness of muck truck drivers is generally weak, and they often overload and overspeed in order to save time and cost of muck transportation, which is the direct cause of such accidents;

[0006] 3. Because the muck truck needs to enter and exit the construction site frequently, in order to ensure its passing ability on uneven roads, its chassis is very high from the ground, which is the main reason for the entanglement and rolling

In addition, after searching the patents in related fields, it was found that there are many designs on movable bumpers, but there is no patent design for muck trucks or for preventing people from being run over by wheels.

Therefore, at present, there is no mature passive safety system at home and abroad, which can protect the people who are hit when a frontal collision accident occurs between a muck truck and a non-motor vehicle or a pedestrian.
