Abstract

The utility model provides a pedestrian protects thigh collision test angle measuring device can better satisfy E -NCAP8.0 rules standard, comprises slide rail, first slider, second slider, first pole, second pole, places pole 1 and pole 2 on IBRL and WAD 930mm respectively, and pole 1 equals with 2 length on the pole that just all perpendicular with the fluting slide rail, pole 2 can slide at the inslot to realize that the different position places of vehicle front end need the fixed of measuring point. Fluting slide rail surface angle beta can be accurately recorded by the protractor, alpha = 90 - beta can be known through how much knowledge conversions. It is perpendicular to assault in orientation and the bumper line according to line and WAD 930mm to E -NCAP8.0 regulation thigh, and it can't direct measurement to have marking tool now, this difficult problem has been solved to this device as to this, has improved measurement accuracy, and has advantages such as easy installation, easy realization.

Description

A kind of pedestrian protecting thigh impulse test angle measurement unit

Technical field

The utility model relates to a kind of pedestrian protecting thigh impulse test angle measurement unit.

Background technology

In pedestrian protecting thigh impact test, the accuracy that pilot region divides directly affects the quality of pedestrian protection test result, affects the exploitation of pedestrian protecting performance simultaneously.Before E-NCAP8.0, in version, thigh angle of attack calculates according to bumper leading edge line of reference height and bumper helical pitch, without the need to measuring.E-NCAP8.0 specifies that thigh impact direction is vertical with the line of WAD930mm with bumper internal reference line, because the line of IBRL (bumper internal reference line) and WAD (envelope) 930mm is inner at vehicle front, existing scoring tool cannot directly be measured, therefore needs to design a kind of device and carry out conversion to it and measure.

Summary of the invention

The utility model is for an existing above-mentioned difficult problem, a kind of pedestrian protecting thigh impulse test angle measurement unit is provided, respectively bar 1 and bar 2 are placed on IBRL (bumper internal reference line) and WAD (envelope) 930mm, rod end point is designed to sharp-pointed round end, improve measuring accuracy on the one hand, be convenient to fix on the other hand; Bar 1 is equal with bar 2 length, and all vertical with slotted track, and bar 2 can slide in groove, thus realize vehicle front diverse location place need the fixing of measurement point, accurately can record slotted track surface angle β by protractor, be transformed by geometric knowledge known, α=90 °-β.

The utility model is realized by following technical measures:

A kind of pedestrian protecting thigh impulse test angle measurement unit, be made up of slide rail, the first slide block, the second slide block, the first bar, the second bar, the first slide block, the second slide block are fixedly mounted in slide rail, and the first slide block, the second slide block can move in slide rail; First bar, the second bar are arranged in the first slide block, the second slide block respectively, along with slide block is fixed in vehicle front diverse location measurement point, the first bar, the second bar are placed on IBRL (bumper internal reference line) and WAD (envelope) 930mm respectively.And then accurately can record slotted track surface angle β by protractor, transformed known by geometric knowledge, α=90 °-β.

The first above-mentioned slide block, the second slide block are T-shaped block, can slide in slide rail, also can be fixed in slide rail.

Porose on the first above-mentioned slide block, the second slide block, the first bar, the second bar can be fixed in hole.

The rod end point of the first above-mentioned bar, the second bar is designed to sharp-pointed round end.

The utility model has very strong practicality, mainly contains following advantage:

1, in the utility model, along vehicle-width direction catch bar 1 and bar 2 simultaneously, realize bar 1 and bar 2 respectively in bumper internal reference line and the enterprising line slip of WAD930mm, by the length of bar, bumper internal reference line and WAD930mm line are converted into the upper surface of parallel lines and slide rail;

2, in the utility model, the rod end point of bar 1 and bar 2 is designed to sharp-pointed round end, improves measuring accuracy on the one hand, is convenient to fix on the other hand;

3, in the utility model, by measuring slide rail surface angle β, accurately can record thigh emission angle α=90 °-β, solving the difficult problem that thigh emission angle cannot be measured;

4, this device also has easy for installation, easily realize etc. advantage.
