Functional component and test device for performance test of automobile anti-collision material

Abstract

The invention discloses a functional component for performance testing of an anti-collision material, which comprises a shell, a driving column, a collision column, a winding reel wound with an electromagnetic coil and a suction block, and is characterized in that the center of the shell is provided with a central cavity along the axial direction, and the driving column is mounted at the upper part of the central cavity and can axially move in the central cavity; the upper portion of the driving column is sleeved with a driving spring, and the lower end of the driving column is connected with the collision column. The driving column is also provided with a locking pin which is inserted from the outside of the shell for locking; a winding reel externally wound with an electromagnetic coil is mounted at the lower part of the central cavity, and the electromagnetic coil is connected with an external circuit; the lower end of the winding reel is tightly pressed with the pull-in block, and the pull-in block is connected with the shell; the collision column penetrates through the winding reel and can stretch out of the suction block. The device has the advantages that the whole device is small in size, high in operability, capable of being used in small test places such as laboratories and high in safety coefficient.

Description

technical field [0001] The invention relates to a testing technology, in particular to a functional component and a testing device for performance testing of automobile anti-collision materials. Background technique [0002] With the improvement of people's living standards, the per capita ownership of cars is increasing. The popularity of automobiles has brought many conveniences to people's lives, but it has also increased the rate of traffic accidents. In order to improve the safety of automobiles and reduce the harm caused by traffic accidents, anti-collision devices are generally installed on automobiles. Set up the anti-collision device, when the car collides and is impacted by external force, the anti-collision device will collapse and absorb the external force, avoiding the rigid impact force from causing damage to drivers, passengers or pedestrians, thereby reducing the loss caused by collision accidents . [0003] At present, many countries have testing requirem...

Problems solved by technology

However, due to the great danger of field testing, it is difficult to achieve, and with the increase of speed, very few devices can reach the speed of car collision in a short time

Moreover, the existing conventional material testing devices are relatively large in size, and are usually tested together with the entire vehicle for collision destructive tests. The cost of the test is relatively high, and there is a certain risk, so it cannot be used in the laboratory.

The Chinese patent application with application number 202110474372.8 discloses a large-load impact test device for short-distance acceleration and short-distance braking. System and other components, the system is complex and bulky, and is mainly used for the safety assessment of special equipment in the environment of high-speed collision accidents during the transportation process of helicopters, transport planes, high-speed rail and other means of transportation, and is not suitable for use in the laboratory at all.
