Description
Technical field
The invention belongs to automotive safety testing apparatus technical field, relate to a kind of line-plotting device of automotive interior protrusion.
Background technology
Along with the high speed development of automobile industry, traffic safety is the common issue that countries in the world face, and strengthens the research of automotive safety, reduces the Road Traffic Injury of China, is that the whole society jointly pays close attention to and makes great efforts one of important social concern solved.In lucky safety technique impact test, all can carry out the demonstration test of each parts in the test of car crass and car every day.In daily traffic accident, the injury of car to passenger inside the vehicle can not be ignored.When getting into an accident, passenger because inertia, can have the trend of motion forward.The head of people is caused to contact with plaques such as the instrument panels of Che Nei.Cause passenger to come to harm, more very then cause death.How dividing the collision area of passenger, is a maximum difficult problem for test.
During inner tabs test before, major part is all that applicant determines Head-Impact area, and applicant adopts at least 48.3Km/h impact velocity, head-on crash condition relative to fixing rigidity barrier walls ± 30 ° scope, determines the mobile order of occupant.Usually the test carrying out 0 ° ,+30 ° and-30 ° can be satisfied the demand.Replace occupant with the 5th hundredths women, the 50th hundredths male sex and the 95th hundredths male sex dummy that grows up, evaluate the Head-Impact area dynamically determined.Because the head-on crash point of dummy has deviation, so the collision area of inner tabs will be controversial, and the collision area that before often can occur to do two places is different, causes the data of test different, to last also neither one basis for estimation qualitatively.
Also there are some line drawing devices in the same industry, as patent (CN203101059U) discloses a kind of pedestrian protection test line-drawing instrument, comprise the base with wheel; Vertically be fixed on the index dial on base; The setting-out bar hinged with index dial; Be positioned at the mark part for setting-out on setting-out bar.The mark that this device does in the marginality position of test vehicle is accurately clear.But the equipment of this patent cannot solve the clear collision area dividing automobile cab inner tabs.
Summary of the invention
