The invention is suitable for the technical field of detection devices, and provides a new energy automobile battery box shell airtightness detection device, which comprises a reservoir filled with water, an eccentric driving assembly, a lifting assembly, a guide limiting assembly, an adjusting assembly, a bearing plate movably connected to the adjusting assembly and on which a to-be-detected battery box is placed, and a detection assembly movably connected to the bearing plate and on which the to-be-detected battery box is placed. A to-be-detected battery box is placed on the bearing plate, after the first motor is connected with an external power source, the output end of the first motor drives the eccentric driving assembly to eccentrically rotate, and the lifting assembly connected with the eccentric driving assembly drives the lifting plate at the bottom to do lifting reciprocating motion; the adjusting assembly connected with the lifting plate is controlled by the lifting motion of the lifting plate to move towards the water liquid in the water storage tank, the compressed air is filled into the battery box by the air source, and when the battery box is immersed in the water liquid, if the battery box is well sealed, the compressed air in the battery box cannot leak, and bubbles cannot appear on the surface of the water liquid.
Description
technical field [0001] The invention belongs to the technical field of detection devices, and in particular relates to a device for detecting the air tightness of a new energy vehicle battery case shell. Background technique [0002] With the development of electric vehicles, power battery packs are the core components of pure electric vehicles, and the safety of battery packs has gradually become prominent, which directly affects the safety of the entire vehicle. The development of battery packs needs to fully consider various factors and needs to learn Absorb advanced technical experience at home and abroad, and repeatedly verify and optimize the design scheme. Therefore, the design requirements for the strength, rigidity, heat dissipation, waterproof, and insulation of the battery box are very high, so the design and sealing test of the battery box are very important. For small pure electric vehicles, the sealing test of the battery box and core is especially important. ...
