[0002] New energy lithium batteries are a common type of battery in modern society. They are generally used as driving energy for automobiles. Usually, several lithium batteries are neatly arranged and fixed in a pre-prepared casing, and then the fixed lithium batteries are connected in series and packaged. They have the advantages of stable discharge voltage and long storage time.

[0003] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. Due to the highly active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream; lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and are rechargeable.

[0004] When conducting tests, existing new energy lithium battery testing devices often perform simulated tests in high and low temperature environments to ensure that they are in line with actual conditions. When switching between high and low temperature environments, most of them require heat dissipation or rewarming inside the testing chamber, which results in heat loss or rewarming of the low temperature environment, increasing energy consumption.

The lithium battery is in contact with the battery, and the screw rod 507 rotates to enable the movable member 506, the connecting rod 504 and the clamping member 502 to assist in clamping the lithium battery, so as to fix the lithium battery. After the fixation is completed, the adjusting rod 509 is moved to separate the gear 1 5012 from the gear 2 5015. At the same time, the adjusting rod 509 is fixed by the limiting member 5011 and the telescopic spring member 5010.

[0042] Working principle: When switching the lithium battery test environment, the electric telescopic rod 309 is started, and the test chamber 305 is driven to rise and fall by the electric telescopic rod 309. At this time, the closing plate 308 can contact the outer wall of the mounting frame 401, so that the pressure spring 3010 is deformed, and then the mounting frame 401 pushes the closing plate 308 down, so that the inside of the flip chamber 402 is connected with the inside of the test chamber 305.

When the test chamber 305 is switched, the driving motor 405 is started, and the driving motor 405 can drive the driving gear 404 to rotate. Since the driving gear 404 is meshed with one of the gear rings 403, the driving gear 404 can drive the gear ring 403 to rotate, and then drive the flip chamber 402 to rotate, so that the flip chamber 402 can be connected with the inside of the test chamber 305 after switching; before the test, the lithium battery is placed on the placement plate 6, and the vibration motor 501 is started at this time, and the vibration motor 501 drives the gear 2 5 015 rotates, and drives the connecting rod and the vibrating member 5014 to move, so that the vibrating member 5014 impacts and vibrates the lithium battery. At the same time, during the vibration, since the gear 1 5012 is meshed with the gear 2 5015, the gear 1 5012 and the adjusting rod 509 can rotate, and then the connecting wire 5013 is wound through the adjusting rod 509. At this time, the connecting wire 5013 can pull the fastening frame 503 and the screw rod 507 to rotate, so that the fastening frame 503 fastens the lithium battery, and the test protrusion contacts the lithium battery. At the same time, the rotation of the screw rod 507 can make the movable part 506, the connecting rod 504 and the clamping Component 502 assists in clamping the lithium battery, thereby fixing the lithium battery. After the fixation is completed, the adjusting rod 509 is moved to separate the gear one 5012 from the gear two 5015. At the same time, the adjusting rod 509 is fixed by the limiter 5011 and the telescopic spring component 5010. When the lithium battery short-circuit catches fire, the delivery pump 703 is started. The delivery pump 703 can deliver the fire-fighting carbon dioxide inside the storage bin 701 to the delivery pipe 704, and deliver it to the inside of the connecting bin 705 through the delivery pipe 704, so that the connecting bin 705 sprays the carbon dioxide through the fire spray hole 706, thereby extinguishing the lithium battery.
