Problems solved by technology

[0007] The above-mentioned safety protection equipment has the following disadvantages: 1, the use of straps will affect the test results because the straps have a certain binding force on the vehicle; 2, the distance between the protective bracket and the tested vehicle is not easy to control, and when the vehicle rolls over, There is an impact with the bracket, which leads to scratches and damage to the prototype vehicle; 3. The test vehicles have different upper structures, and it is difficult to find a suitable support point for the protective bracket to meet the test requirements of all vehicles; 4. The adjustment of the equipment is cumbersome and cannot be followed in time. Safety protection

Abstract

The invention provides an anti-rollover device of an automobile rollover test bench. The anti-rollover device comprises a hydraulic system, an electric control system, a supporting base assembly and asupporting frame assembly, and is characterized in that the hydraulic system provides power for the whole supporting device, and an inclination angle of the supporting frame assembly can be changed by means of a power device in the hydraulic system; the electric control system forms a closed-loop control system and controls the hydraulic system according to parameters acquired by means of a signal acquisition device, so as to ensure that the supporting frame assembly is kept at a preset angle; the supporting base assembly is used for guaranteeing movement of the supporting frame assembly; andthe supporting frame assembly is used for supporting an overturned sample vehicle to ensure the safety of the sample vehicle in the test process. The anti-rollover device is adopted, so that the testrisk is reduced, the test safety is ensured, and the precision of the test result can be ensured.

Description

technical field [0001] The invention relates to the field of detection equipment for automobiles and components thereof, in particular to an anti-rollover device of a rollover test bench for automobiles and a method for using the rollover test bench. Background technique [0002] The roll stability angle of a vehicle is an important indicator for evaluating the safety of vehicle operation. The standards GB 7258-2017 and GB / T14172-2009 have clear requirements for the roll stability angle and test methods of various types of vehicles. This test is mainly realized by driving the vehicle under test to turn over together through the rollover test bench. In order to test the safety of the vehicle, during the test, safety protection equipment is required to protect the tested vehicle and prevent the vehicle from rolling over without affecting the test results. [0003] For example, in the prior art, the invention patent with the publication number of CN103278333A discloses a rolli...
