Description

Technical Field

[0001] The utility model belongs to the technical field of automobile collision test, and more specifically, particularly relates to a detection device for automobile safety performance engineering anti-collision test. Background Art

[0002] At present, automobile driving technology is moving towards the intelligent era. Among them, the active braking system, as a key link in the verification of automobile intelligent safety performance, has attracted much attention. In the collision avoidance test of the active braking system, collision dummies play an indispensable role. These dummies are designed to be very similar to real bodies in size and appearance. They can be effectively identified as pedestrians by the radar, camera and other sensors equipped in the car, thereby triggering the vehicle's active braking mechanism for collision avoidance tests. Existing collision dummies are generally composed of a torso and a mounting plate. When necessary, the mounting plate can be connected to a rail trolley to conduct collision avoidance tests on moving humans.

[0003] Existing application number: CN202020806497.7. The utility model provides an anti-collision movable dummy for autonomous driving tests, which is used in automobile collision tests and includes a dummy body, a fixed seat, a drive motor, a driving wheel, a track and an automobile detection mechanism. The automobile detection mechanism includes an infrared transmitting tube, an infrared receiving tube and a controller. When the car passes between the infrared transmitting tube and the infrared receiving tube, the propagation of infrared light is cut off. The controller controls the drive motor to drive the fixed seat and the dummy body to move along the track. When the car moves to the track, it can collide with the dummy body and separate the dummy body from the fixed seat, thereby simulating the real situation of a pedestrian being hit by a car, and providing more appropriate and practical test data for automobile tests.

[0004] Based on the above, since the dummy's feet have limited area, in order to ensure that it stands firmly on the ground, the soles of the dummy's feet are often equipped with mounting plates that expand the contact area. However, when conducting mobility dummy tests, this design becomes inconvenient when it needs to be connected to a rail car. Additional tools such as bolts are needed to fix the mounting plate and the rail car, which not only increases the complexity of the operation, but also reduces the operating efficiency.
