The battery not only directly determines the vehicle's range, but also has a decisive impact on the vehicle's power performance and safety performance. However, with the rapid growth of new energy vehicles, battery safety issues have become increasingly prominent, and serious accidents such as battery thermal runaway, fire, and explosion occur from time to time. These accidents not only pose a huge threat to the safety of users' lives and property, but also have a negative impact on the healthy development of the new energy vehicle industry.

The device, through the coordinated use of the vacuum component, the sealing door and the detection chamber, after a fire occurs, the vacuum pump is started to extract the gas in the detection chamber, and the generated toxic gas is extracted and transported to the air purification box for adsorption, purification and filtration treatment, so as to reduce or even remove the toxic gas in the detection chamber. At the same time, through the coordinated use of the puncture component and the positioning groove, the device can adjust the relative position of the puncture needle on the pressure plate as needed to realize puncture tests at different points and improve the accuracy of the test results.

[0004] However, when the device is performing puncture detection on the battery, if the battery short-circuits and causes a malfunction, the puncture component cannot be detached from the inside of the battery in time, which can easily cause damage to the device itself, thereby affecting subsequent battery safety detection. Therefore, a new energy vehicle battery safety detection device is proposed to solve the above-mentioned problems. Summary of the invention

The telescopic pole 6 moves downward to contact the positive and negative electrodes of the battery pack 7, thereby simulating the short circuit of the positive and negative electrodes of the battery pack 7, detecting the current and temperature changes of the battery pack 7 during the short circuit, and avoiding the battery pack 7 from being unable to cut off the circuit in time or overheating during the short circuit. At the same time, during the detection process, if the resistance of the battery pack 7 is too large, resulting in too high a battery temperature, and then a fire occurs, the detection module 18 will detect the smoke mixed in the air, and then send a signal to start the motor 9.

At the same time, when the conveyor table 3 moves to transport the battery pack 7, the battery pack 7 will move forward and deviate, thereby affecting the inspection of the battery. When the battery is inspected, the I-beam 5 moves downward to drive the L-shaped rod 109 to move, and the movement of the L-shaped rod 109 drives the inclined bar 1010 to move. When moving downward, the inclined bar 1010 will contact the battery pack 7 and push the battery pack 7 to move through the extrusion force generated by the inclined surface of the inclined bar 1010, thereby being able to more accurately ensure the position of the battery pack 7, so that the accuracy of the inspection can be further improved.
