The invention relates to a test zone dividing device for automobile and pedestrian protection tests, comprising a trolley base, four castors and a stand column foundation bed arranged on the trolley base, wherein the lower end of a stand column is connected with the stand column foundation bed, a lifting screw rod is in matching connection with an upper support and a lower support which are arranged at the upper and lower end parts of one side of the stand column; one end of a cross arm is in matching connection with a cross arm fixed foundation bed, and the cross arm fixed foundation bed is in matching connection with a sliding rail at the other side of the stand column and is matched with the lifting screw rod; the upper part of a short sliding arm is connected with the other end of the cross arm by a hinge structure; and one end of a line drawing rope is connected with a support lug on one end of the short sliding arm, and the other end of the line drawing rope is connected with a tensioning component on one end of the short sliding arm. As the lifting stroke of the cross arm, and the moving stroke and the rotating angle of the short sliding arm can be adjusted, the operation is simple and convenient, and the test zones of the automobile and pedestrian protection tests can be rapidly and accurately divided, so as to improve the efficiency of the automobile and pedestrian protection tests and the line drawing accuracy.
Description
technical field [0001] The invention relates to an automobile pedestrian protection test, in particular to a test area dividing device for the automobile pedestrian protection test. Background technique [0002] In order to strengthen the protection of pedestrians, non-motor vehicle drivers and other vulnerable road users in traffic accidents, and reduce the number of serious injuries or deaths caused by traffic accidents, my country has formulated GB / T 24550-2009 Automobiles to Pedestrians Collision Protection Regulations. According to the regulations, when conducting a car-to-pedestrian collision test, it is necessary to divide the test area at the front of the car. At present, there is no dedicated domain division device in China that can quickly and accurately divide the test area of the car-pedestrian protection test, causing car pedestrians The efficiency of the protection test is low and the accuracy is poor. Contents of the invention [0003] The purpose of the ...
