[0002] With the rapid development of new energy technology, new energy batteries as the core components in the field of new energy, their safety problems are increasingly concerned. New energy batteries may be affected by various external forces and extreme working conditions during use, such as extrusion, collision, high temperature, etc. These factors may cause battery failure, even cause explosion, combustion and other serious safety accidents. Therefore, safety detection of new energy batteries is an important means to ensure their quality and safety.
[0003] However, the existing new energy battery safety detection device has some shortcomings. On the one hand, the existing safety detection device has defects in explosion-proof performance, which cannot effectively deal with the explosion of the battery during testing, cannot release pressure in time, and may cause greater safety hazards. On the other hand, the existing detection device is not perfect in buffer protection, which cannot fully absorb and disperse the energy generated when the battery explodes or is impacted by external force, and is easy to cause great damage to the equipment and the surrounding environment. In addition, the existing detection device also has some shortcomings in the flexibility of simulating different working conditions, which is difficult to accurately simulate various complex external force conditions that the battery may encounter in actual use, resulting in certain influence on the accuracy and reliability of the detection results.
[0004] Therefore, the present application provides a new energy battery safety detection device to solve the above problems. UTILITY MODEL CONTENT

Its application value in new energy battery safety testing is remarkable, and it provides strong technical support for the research and development, production and safe use of batteries.
