Launch device for pedestrian protection head module crash test

Abstract

The invention discloses a launch device for pedestrian protection head module crash test. The launch device comprises a supporting mechanism, an angle adjusting mechanism and a launch device body. Two sides of the rear end of the launch device body are movably hinged to the supporting mechanism, and the supporting mechanism comprises a supporting box, a guide mechanism, a connection release mechanism, an energy accumulation mechanism, an uncoupling mechanism and a traction mechanism, wherein the guide mechanism is fixed in the supporting box, and the connection release mechanism, the energy accumulation mechanism, the uncoupling mechanism and the traction mechanism are connectedly arranged on the supporting box sequentially from front to back and in slide fit with the guide mechanism. The angle adjusting mechanism is movably hinged to the supporting mechanism and the launch device body and used for adjusting a launch angle of the launch device body. The launch device has advantages that head module launch angle adjustment in -20-90 degrees can be realized by a low cost, and a maximum launch speed of 11.5m / s is realized; the launch device can be used for crash force analysis of the pedestrian head module and an automobile front windshield and windshield damage mechanism research; compactness in design, structural simplicity, low cost and convenience in manufacturing and maintenance are realized.

Description

technical field [0001] The invention relates to a launcher for a collision test of a head module for pedestrian protection, in particular to a launcher for a collision test of a head module for pedestrian protection that can meet the test requirements of automobile pedestrian protection regulations. Background technique [0002] According to statistics, the number of road traffic deaths in my country in 2015 was about 42,000, of which about 60% were pedestrians and other vulnerable road users. Legislative work. Studies have shown that the head is the most vulnerable part of pedestrians to fatal injuries, and it is a major cause of casualties in traffic accidents. [0003] At present, the test devices used for pedestrian protection research in countries around the world are basically monopolized by foreign manufacturers. Most of their products use closed-loop controlled pneumatic or hydraulic launch systems, and most of them are general-purpose equipment that can be applied t...

Problems solved by technology

[0003] At present, the test devices used for pedestrian protection research in countries around the world are basically monopolized by foreign manufacturers. Most of their products use closed-loop controlled pneumatic or hydraulic launch systems, and most of them are general-purpose equipment that can be applied to all subsystems in pedestrian protection regulations. Experiments, this type of equipment is bulky, complex and expensive, and the cost of researching pedestrian head protection collisions is too high
