AI Technical Summary

Technical Problem

In existing technologies, the strength testing equipment for new energy vehicle chassis lacks precision when fixing battery pack chassis of different sizes and shapes, making it difficult to simulate real-world environments and resulting in inaccurate test results.

Method used

A structure including a top suspension, a main stroke frame, a secondary stroke frame, and a drive frame was designed. Combined with an electromagnet assembly and a changeover plate, it can quickly fix chassis of different sizes. Different force conditions are simulated by rectangular hammers, wedge hammers, and pressure hammers. With the help of servo motors and lead screws, precise movement and fixation are achieved.

Benefits of technology

It enables rapid fixing and precise testing of battery pack enclosures of different sizes and shapes, and can simulate stress conditions such as rolling, impact, and extrusion, thus improving the accuracy and adaptability of the test.

Abstract

The application relates to the technical field of battery pack case strength test, in particular to a new energy automobile case shell structure strength test structure, which comprises a top suspension, a main stroke frame is slidably connected to the outer side of the top suspension, and a vice stroke frame is slidably connected to the left side of the main stroke frame. The application provides a new energy automobile case shell structure strength test structure, which has the advantages that the output assembly can be moved to the position directly above the required detection position, then the driving frame vertically falls along the vice stroke, the downslide track also falls, and first contacts the top of the test case; as the driving frame continuously falls, the electromagnet assembly connected to the driving frame also falls, at this time, the tension spring is stressed and elongated, the electromagnet assembly can continuously keep the electrified state when falling, the shape part on the inner side is adsorbed when passing the group changing disc, and the shape part is vertically pressed, and directly acts on the surface of the test part to compress the stress.
