Description

Technical Field

[0001] The utility model relates to the technical field of motor vehicle safety performance detection, and specifically relates to a motor vehicle safety performance detection device. Background Art

[0002] With the development of social economy, the number of motor vehicles continues to increase, and the number of road traffic accidents is also increasing. In order to protect the safety of people's lives and property, the state pays more and more attention to the safety performance testing of motor vehicles. Motor vehicle safety performance testing is one of the important means to prevent and reduce traffic accidents, and it is also an important system for the implementation of safety management of motor vehicles. Anti-collision performance is an important part of motor vehicle safety performance, which is directly related to the safety of the vehicle in an accident. Anti-collision detection can timely discover safety hazards of vehicles, improve vehicle safety, and reduce the occurrence of traffic accidents.

[0003] When conducting anti-collision tests on motor vehicle safety performance, multiple aspects are tested, including body structure testing. Among them, suspension testing is particularly important. The suspension system is the bridge between the car and the road. It needs to effectively absorb the impact from the road while maintaining the stability and controllability of the vehicle. Poor anti-collision effect of the suspension system may cause excessive vibration and noise during driving, affecting the driving experience and ride comfort. However, if the bumper has poor anti-collision effect, other parts of the body may be severely damaged in the event of a collision, and even cause the vehicle to be scrapped.

[0004] In addition, the anti-collision test of the suspension system can also evaluate the safety of the vehicle structure, such as whether it is sturdy after installation and whether the whole is stable. Therefore, we propose a motor vehicle safety performance testing device to ensure the safety of the vehicle. Utility Model Content

[0010] Preferably, the frame is concave in shape, and an opening is provided at the top.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: when the safety performance of the suspension beam is impacted, the impact structure and the column structure are set for detection, an electromagnet is set to adsorb the suspension beam, the other end of the electromagnet is pulled by the hydraulic cylinder, and the compression spring on one side of the suspension beam is compressed. When the electromagnet is released, the suspension beam is ejected outward by the strong torsion of the compression spring and hits the pre-set column. During the impact process, the contact surface between the suspension beam and the column can produce a certain plastic deformation, and the safety performance is detected through multiple impacts. At the same time, the column structure has an adjustment function and can hit different points of the suspension beam, which makes the anti-collision test of the suspension beam more flexible and accurate. Different impact points can be selected according to different test requirements to ensure the accuracy and reliability of the test results. Through the coordinated work of the electromagnet, the hydraulic cylinder and the compression spring, the impact operation of the suspension beam becomes simple and easy, without complicated operating steps and skill requirements. Through the setting of the compression spring and the column, it can be ensured that the impact point is consistent with the test target, thereby improving the accuracy and reliability of the test results, which is helpful to evaluate the safety performance of the suspension beam and provide a basis for maintenance or replacement.
