Description

Technical Field

[0001] The invention relates to the technical field of battery storage, and in particular to a novel explosion-proof lithium battery storage box. Background Art

[0002] Lithium batteries have been widely used in electric vehicles, energy storage systems, electronic products, aerospace and other fields due to their high energy density, long life and environmental protection. However, lithium batteries also have certain safety risks during use, such as overcharging, over-discharging, short circuit, etc., which may cause the battery to catch fire or explode. Therefore, higher requirements are placed on the safety performance of lithium batteries, and new explosion-proof lithium battery storage boxes have emerged. For example, in the patent with application number: CN202320501832.6, it specifically involves a fireproof and explosion-proof storage box for power lithium batteries. The box body is the storage part of the lithium battery, and a controller is installed on one side of its surface, an automatic dry powder fire extinguisher, which is installed on one side of the surface of the box body and extends to the inside of the box body, a thermostat, which is installed on the inner wall of the box body and is electrically connected to the controller, and a temperature sensor, which is installed on the inner wall of the box body, and the temperature sensor and the controller are connected by a signal line. The utility model overcomes the shortcomings of the prior art. By setting a controller, a thermostat and a temperature sensor, after a person puts a lithium battery into a storage box, he can adjust the required temperature of the lithium battery storage box through the display screen on the controller. When the temperature inside the lithium battery storage box is too high, the temperature sensor will sense it and then transmit the signal to the controller. After receiving the signal, the controller starts the thermostat, thereby preventing the lithium battery temperature from being too high.

[0003] The current structure of lithium battery storage boxes is relatively simple and lacks an all-round buffer structure. In the event of a collision, the lithium battery is easily damaged and burned. Summary of the invention

[0006] Furthermore, a square opening is provided in the middle of the inner partition plate and the inner clamping plate, and the square opening is opposite to the explosion-proof net. Square openings are also provided in the middle of the three groups of bottom support plates.

[0007] Furthermore, both ends of the first inserted connecting rod are respectively provided with a threaded structure, one end is screwed into the threaded hole of the explosion-proof box, and the other end is screwed with a retaining nut. The second inserted connecting rod is slidably inserted on the inner partition, and both ends are also provided with a threaded structure, and are screwed with a retaining nut.

[0008] Furthermore, two groups of side clamps are respectively provided at the two ends of the inner side of the side baffle, and the two groups of side clamps are respectively slidably installed on the third interpenetrating connecting rod through the external connecting plates B on both sides thereof. The two ends of the third interpenetrating connecting rod are respectively provided with threaded structures, one end is screwed into the threaded hole of the side baffle, and the other end is screwed with a locking nut.

[0009] Furthermore, the width of the side clamping plate is smaller than the width of the side baffle plate, and a side clamping spring is provided between the side clamping plate and the side baffle plate.

[0010] Furthermore, the front and rear sides of the three groups of lithium battery storage cavities are respectively provided with inner baffles, and the inner baffles are placed on the outside of the top end of the groove and do not contact the bottom supporting plate.

[0016] In addition, convenient power connection solution: In order to facilitate the power connection of the lithium battery, a metal plug is designed on the top plate. After the top plate is flipped over, the plug can be easily inserted into the connecting column of the lithium battery to achieve fast and reliable power connection.
