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
Technical field
The present invention relates to the method for application of test unit and this test unit of auto parts and components, relate in particular to a kind of pedestrian protecting shank collision test device and method of application thereof.
Background technology
Development along with society; Automobile begins to come into huge numbers of families as a kind of walking-replacing tool; And automobile is also paid close attention to for people as its security performance of a kind of vehicles day by day, and its security not only is confined to protect passenger's safety, can effectively protect pedestrian's safety but also require automobile in a single day to bump with the pedestrian; China formally implements GB/T24550-2009 in beginning on July 1st, 2010 for this reason, and promptly automobile is to pedestrian's crash protection national standard.Statistical result showed, pedestrian's leg injury is more common during collision, and the lighter is pedestrian's shank skin and flesh scratch, and weight person directly causes the pedestrian lower leg fracture, so the pedestrian protecting leg function during car crass is the important indicator of evaluation vehicle safety.And existing automobile pedestrian protection test normally carries out on car load; Because the structure of vehicle front is the key that influences the pedestrian lower leg security performance, generally be through the front end emission shank crash module of shank crash module emitter when therefore testing to vehicle, there is degree of impairment to judge the pedestrian protecting shank security performance of vehicle according to the shank crash module then; Because test is carried out on the entity vehicle; Therefore a vehicle car load that often need destroy several even tens could be accomplished this safety feature test, will reprocess the destruction vehicle after the test, and the test period is long; Cost is high; And this kind test method needs after car load is succeeded in developing and assembled, to carry out, and in the car load performance history, can't detect the security performance of related components, causes the automobile development cycle long for this reason; Often revise mould even die sinking again when parts need improve, R&D costs are high.
Summary of the invention
The present invention has mainly provided a kind of simple in structure; Can carry out simulated collision test to many moneys vehicle; And the related components on the vehicle directly carried out simulated collision test on test unit, thus improve the pedestrian protecting shank collision test device and the method for application thereof of the accuracy of test figure, having solved the simulated collision test that exists in the prior art can only carry out on the entity vehicle; Cause the test period long, the technical matters that experimentation cost is high.
Above-mentioned technical matters of the present invention mainly is able to solve through following technical proposals: a kind of pedestrian protecting shank collision test device; Comprise pedestal and be located at the shank crash module emitter on the pedestal; On pedestal, be connected with a pair of the support down column, a pair of front beam installation column and a pair of hood hinge installation column are installed corresponding to shank crash module emitter front side; Three columns are arranged in order from inside to outside and relative respectively shank crash module emitter is symmetrical distribution; Between the pedestal that supports corresponding to twice between installation column and the two front beams installation column, be provided with a hood lock catch column is installed, the top that column and hood lock catch installation column are installed at said hood hinge installation column, front beam is respectively equipped with height regulating rod.Through the column that several are used for fixing following support endergonic structure, front beam assembly and the endergonic structure and the engine casing assembly of vehicle is set on pedestal,, make three's height consistent during semi-load apart from floor level with vehicle to be measured through the height of three parts of height regulating rod up-down adjustment on the column; Again through regulating the front and back position of column; Make on triangular front and back position and the vehicle to be measured triangular physical location consistent, promptly the fixed form of three parts and position relation is consistent with the actual conditions of vehicle, can satisfy testing requirements thereby process of the test need not the entity vehicle; Experimentation cost is low; The accuracy of test figure is high, and is easy to install, shortens the test period; And again can be through regulating the testing requirements that height regulating rod on column and the column satisfy different automobile types, versatility is good.
