Description

Technical Field

[0001] The utility model relates to an angle adjustment mechanism for a mounting plate of a battery pack bottom scraping test vehicle, belonging to the technical field of automobile testing equipment. Background Art

[0002] Vehicle underbody scraping is primarily caused by the front wheel suddenly dropping (over a bump or into a pothole) while driving, causing the vehicle body to sink into contact with the ground. The battery pack, mounted on the underbody of a new energy vehicle, is a critical area requiring significant protection. Whether the battery pack's underbody protection is protected from crushing, deformation, or shattering when subjected to a sudden impact is a key component in determining whether the pack's underbody protection meets the required standards.

[0003] In order to test the anti-scratch performance of the underbody of new energy battery vehicles, existing motor vehicle inspections mainly conduct anti-scratch experiments on battery packs by simulating the road conditions under which the car is running. However, it is difficult to accurately set the required road conditions for various situations and it is difficult to obtain the required various test data. In addition, complex road condition settings require long distances and high costs. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figure 1 、 2 As shown, a mounting plate angle adjustment mechanism for a battery pack scraping test vehicle includes a hinge shaft 1 disposed between the front end of the mounting plate 5 and the frame 4, and a telescopic cylinder 2 mounted at the rear of the frame 4. The telescopic rod 201 of the telescopic cylinder 2 is connected to the rear of the mounting plate 5. The telescopic cylinder 2 is extended and retracted to cause the mounting plate 5 to rotate about the hinge shaft 1. In this way, testers can conveniently adjust the angle of the mounting plate of the battery pack scraping test vehicle by controlling the extension and retraction of the telescopic rod 201, allowing the bottom surface of the battery pack 6 mounted on the mounting plate 5 to be scraped and impacted by ground obstacles at various angles, thereby accurately obtaining various test data.

[0022] There are two telescopic cylinders 2, which are respectively installed on the left and right sides of the rear part of the frame 4.
