Embodiment
[0038] Such as figure 2 and image 3 , the main parts that affect pedestrian leg collision are the engine cover assembly 100, the front beam assembly and its energy-absorbing structure 200, and the lower support energy-absorbing structure 300. This patent uses a pedestrian protection leg collision test bench device to The above three main components are connected together, and then the pedestrian protection leg impact test is carried out. This method solves the preliminary judgment of the leg collision performance of the key components of pedestrian protection without fully developing the vehicle, and provides a design basis for the subsequent development of pedestrian protection performance.
[0039] Also see figure 1 , a pedestrian protection leg impact test device of the present invention, comprising a square test bench base 1, the test bench base 1 is fixed on the level ground, at a position close to the front end of the test bench base 1 A leg collision module launch...

The invention discloses a collision test device for protecting legs of pedestrian and use method thereof, and provides a collision test device for protecting legs of pedestrian and use method thereof, wherein the collision test device for protecting legs of pedestrian is simple in structure, the simulation collision test is implemented on the automobiles in different types, the simulation collision test of the related part of the automobile is directly implemented on the test device, so that the accuracy of the test data is improved, the technical problems that the simulation collision test in the prior art is only implemented on the real automobile, the test period is long and the test cost is high and the like are solved. In the collision test device for protecting legs of pedestrian, a lower support energy absorption structure of the automobile, a front beam assembly and energy absorption structure and an engine hood assembly are fixed on several columns of the base to regulate the position among the columns, so that three parts are maintained on the relative position while the automobile is in the half loading state; a leg collision module is transmitted via a leg collision module transmission device to implement the simulation collision, and then the safety of the automobile for protecting the legs of pedestrian is judged according to the breakage of the leg collision module.
Description
[0001] technical field [0002] The invention relates to a test device for auto parts and a method for using the test device, in particular to a pedestrian protection leg impact test device and a method for using the same. Background technique [0003] With the development of society, automobiles, as a means of transportation, have begun to enter thousands of households, and the safety performance of automobiles as a means of transportation has also attracted people's attention day by day. It is required that once a car collides with a pedestrian, it can effectively protect the safety of pedestrians. For this reason, my country has officially implemented GB / T24550-2009 on July 1, 2010, which is the national standard for collision protection between cars and pedestrians. Statistical results show that leg injuries of pedestrians in collisions are relatively common. The light ones are skin and flesh abrasions on pedestrians' legs, and the severe ones directly cause pedestrians' ...
