Technical Field

[0001] The utility model relates to the technical field of automobile testing, and particularly relates to a supporting device for automobile testing. Background Technique

[0002] During the use of an automobile, as the service time prolongs or the driving mileage increases, its parts gradually wear, corrode, deform, age, and the lubricating oil deteriorates, etc., resulting in an increase in the clearance of the mating pairs, causing looseness in movement, vibration, rattling, air leakage, water leakage, oil leakage, etc., and causing a decline in the technical performance of the automobile. Automobile testing is to check the technical condition or working ability of the automobile. When troubleshooting vehicle faults or testing vehicle performance, the automobile will be supported to troubleshoot the faults of the chassis parts of the automobile or conduct corresponding tests;

[0003] The Chinese publicly authorized invention: CN220322717U discloses a supporting device for automobile testing, including a base, a support rod, a support and limiting mechanism, a lifting mechanism, a fixing mechanism, and a lifting mechanism driving mechanism; four support rods are evenly distributed on the base, a lifting groove is opened on one side of the support rod, a lifting mechanism is arranged inside the lifting groove, the four ends of the support and limiting mechanism respectively extend into the four lifting grooves and are fixedly connected with the corresponding lifting mechanisms, a part of the lifting mechanism driving mechanism is arranged inside the base, the working end of the lifting mechanism driving mechanism is connected with the lifting mechanism, sliding grooves are provided on the other side of the support rod, the protrusions beside the four ends of the support and limiting mechanism respectively extend into the four sliding grooves, a plurality of slots extending to the sliding grooves are opened on one side of the support rod opposite to the lifting groove, and the fixing mechanism is inserted into the plurality of slots; this device prevents the lifting machine from falling off due to a malfunction during testing by limiting the automobile wheels and fixing the testing height of the automobile.
