Problems solved by technology

However, in the actual experimental process, once the volume of the product is large and the surface area in contact with the air is large, the differential pressure method appears to be poor in stability and repeatability.
Although we can use the same product as a comparison part, due to the large variety of battery pack products, the general customer will not choose to install the test method of the comparison part

Abstract

The invention discloses a helium detector for an automobile storage battery box. The detector comprises a table frame, a working part is arranged on the table frame, the working part comprises a mounting plate, the mounting plate is fixedly mounted on the table frame, and a front-back transplanting device, a vacuum box and a leakage detection device are arranged at the top of the mounting plate. The front-back transplanting device is used for installing and moving a storage battery box, the vacuum box is used for fixing and blocking the storage battery box, and the leakage detection device isused for detecting whether the storage battery box leaks air or not. Through arrangement of the front-back transplanting devices, the vacuum box and the leakage detection device, movement, sealing, vacuumizing, helium filling, helium leakage detection and the like of the storage battery box can be realized, so that the airtightness detection of the battery box is realized; meanwhile, helium is used as detection gas, so that the detection is more sensitive and accurate.

Description

technical field [0001] The invention relates to the technical field of a battery box helium detector, in particular to an automobile battery box helium detector. Background technique [0002] With the development of electric vehicles, power battery Pack, as the core component of pure electric vehicles, directly affects the safety of the whole vehicle. The development of the battery pack needs to fully consider various factors, learn and absorb advanced technology experience at home and abroad, and repeatedly verify and optimize the design scheme. Therefore, the design requirements for the strength, stiffness, 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. The use of air-tight leak detectors has strong regularity and data traceability can be achieved. Once a product has a problem, it can be traced back to the product status or data when it was first shipped. The subjectivity...
