The specific embodiment is as follows:

example 1: auxiliary platform device

The structure of the speed measuring mechanism comprises: a leg-type test tachymeter 20 and a head-type test tachymeter 24.

As shown in fig. 1 to 4, the head-type test velocimeter 24 is mounted on the head-type test-side image-taking adjustment pan/tilt 15, and the head-type test-side image-taking adjustment pan/tilt 15 is fixed to the top end of the external speed-measuring height adjustment lever 52 by a stud on the pan/tilt fixing and connecting mechanism 54. In order to measure the head type impact tests of different heights, the height of the external speed measuring height adjusting lever 52 is adjusted by the external speed measuring height adjusting lever fixing and adjusting knob 55. When the pedestrian protects the leg type experiment, the leg type impacter is lower apart from ground, in order to guarantee the measurement of the experimental speed of leg type, the experimental tachymeter 20 of using of leg type is installed on the experimental tachymeter adjustment cloud platform 53 of leg type impact test, the experimental tachymeter adjustment cloud platform 53 of leg type impact test passes through the screw rod on cloud platform fixed connection 54 to be fixed on the experimental tachymeter of leg type impact test puts base 19, the experimental tachymeter of leg type impact test puts base 19 of leg type impact test and puts the base through the experimental tachymeter of leg type impact test and fastener connecting bolt 58 and fastener 56 are fixed together, fastener 56 adjusts the height of the experimental tachymeter 20 of using of leg type through the elasticity of fastener bolt 57. Outside height regulating pole 52 (bottom) tests the speed through the welding with it fix outside height regulating pole that tests the speed move with the slider connection fixed plate 60 on, in order to make outside height regulating pole 52 that tests the speed fixed firm, outside height regulating pole 52 (bottom) tests the speed through the welding with outside height regulating pole strengthening rib 59 that tests the speed with outside 52 (bottom) and outside height regulating pole that tests the speed move with slider connection fixed plate 60 together, because its triangular structure, can make outside height regulating pole 52 that tests the speed fixed more stable. Since the position of the head type test point is from the front engine cover of the vehicle to the windshield, in order to enable the head type test velocimeter 24 to move along the vehicle X-axis direction and to enable the outer speed-measuring height-adjusting rod 52 to be fixed more stably, the outer speed-measuring height-adjusting rod moving slider-connecting-fixing plate 60 connects the two outer speed-measuring height-adjusting rod moving sliders 62 together, the outer speed-measuring moving linear guide 28 is fixed on the main frame lower longitudinal beam 26 by bolts, and the outer speed-measuring height-adjusting rod moving slider 62 is installed on the outer speed-measuring moving linear guide 28, so that the head type test velocimeter 24 can move along the vehicle X-axis direction.

In order to ensure that the test angle of the velocimeter 20 for leg type test can meet the requirement of leg type test speed measurement: keeping 0 degree in the X direction and the leg type impact direction, and ensuring that the light beam emitted by the velocimeter 20 for leg type test is horizontally emitted and 0 degree in the Y direction. Therefore, the angle requirement of the leg type test tachymeter 20 can be ensured by adjusting the leg type impact test tachymeter adjusting pan head 53 fixed to the leg type test tachymeter 20 and confirming the angle measuring instrument. The requirements of the head impact test on the velocimeter 24 for the head test: when the head shape of the child is impacted, the included angle between the head shape and the ground along the X-axis impact direction of the vehicle is 50 degrees, and when the head shape of the child is impacted, the included angle between the head shape and the ground along the X-axis impact direction of the vehicle is 60 degrees and 65 degrees.
