DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1

[0024] Please refer to Figures 1 - 3 , this embodiment provides a lithium battery charge and discharge test warning system, a protection system and a test box, including a box body 1. A protection mechanism 2 is provided on the box body 1. By using the protection mechanism 2, the protection performance of the device is enhanced to prevent the box body 1 from being damaged and causing danger. A heat dissipation mechanism 3 is provided on the top of the box body 1. By using the heat dissipation mechanism 3, the heat dissipation performance of the device is increased to prevent the temperature inside the box body 1 from being too high and generating danger. A limiting mechanism 4 is arranged in the middle of the inner cavity of the box body 1 to facilitate the limiting and fixing of the lithium battery. A clamping mechanism 5 is arranged inside the limiting mechanism 4 to facilitate the clamping and fixing of the wiring terminals of the lithium battery and facilitate the wiring of the lithium battery. A fire prevention mechanism 6 is arranged on the top of the limiting mechanism 4 in the inner cavity of the box body 1 to increase the fire prevention performance of the device. An alarm 7 is arranged at the bottom of the limiting mechanism 4 in the inner cavity of the box body 1 to facilitate high-temperature alarm;

[0025] In the existing equipment, there is a lack of a protection structure. When the quality of the lithium battery is unqualified, during the charge and discharge process, it is prone to the danger of combustion and explosion. At this time, the door of the test box is likely to open due to the impact, and even the door of the box is damaged, resulting in danger.

[0026] In this embodiment, in order to enhance the protection performance of the device, prevent the box body 1 from being damaged, and prevent the protection door from opening due to the impact, the protection mechanism 2 includes a protection layer 21 and a protection door 24. The protection layer 21 is arranged in the inner wall sandwich of the box body 1. Support blocks 22 are evenly and fixedly connected inside the protection layer 21 to enhance the protection performance of the outer wall of the box body 1, increase its impact resistance, and prevent it from opening after being impacted. Two electric push rods 23 are installed at the top and bottom of the protection layer 21 respectively. The output end of the electric push rod 23 is inserted into the inner wall of the protection door 24. A reinforcing plate 25 is fixedly connected to the inner wall of the fire prevention door 24. A slot adapted to the output end of the electric push rod 23 is opened on the inner wall of the protection door 24. The protection door 24 is hinged to one end of the outer wall of the box body 1. A handle is fixedly connected to the outer wall of the protection door 24 through bolts. By using the electric push rod 23 to drive the output end to be inserted into the top slot of the protection door 24, the protection door 24 can be tightly closed.

[0027] When this structure is in use, the protective door 24 is switched by the handle. When the protective door 24 is closed, the output end of the electric push rod 23 is inserted into the protective door 24 to prevent the protective door 24 from being opened by impact, which affects the use. When the protective door 24 needs to be opened, first open the electric push rod 23 to drive the output end to fall off the protective door 24, and then open it to facilitate the use of the device.

[0030] In order to increase the heat dissipation performance of the device and prevent danger caused by excessive temperature, by using the heat dissipation mechanism 3 including a heat dissipation fan 31 and a ventilation fan 35, the heat dissipation fan 31 is fixedly connected to the top of the box body 1. There are two air inlets on the top of the heat dissipation fan 31, and air inlet filters 32 are clamped on the air inlets to facilitate the input of external air while preventing the entry of impurities. The two ends of the heat dissipation fan 31 are both passed through by a conveying pipeline 33. One end of the conveying pipeline 33 away from the heat dissipation fan 31 passes through the outer wall of the box body 1, and one end of the conveying pipeline 33 passing through the protective layer 21 is fixedly connected to a gas spray head 34. The ventilation fan 35 is fixedly connected to the bottom of the inner cavity of the box body 1. The number of ventilation fans 35 is two, and the two ventilation fans 35 are fixedly connected inside the protective layer 21. A dust-proof net is clamped at the bottom of the ventilation fan 35, and the internal air is discharged by using the ventilation fan 35.

[0031] When this embodiment is in use, first, the heat dissipation fan 31 is turned on to drive the outside air to enter the box body 1 through the conveying pipeline 33, and the ventilation fan 35 is used to drive the internal air to be discharged, which facilitates the continuous flow of air and increases the heat dissipation performance of the device.

The four fire extinguishing agent spray nozzles 62 are respectively fixedly connected to the top of the inner cavity of the support groove 41. When the temperature sensor detects that the temperature is too high, the fire extinguisher inside the fire prevention box 61 is opened to spray the fire extinguishing agent, which is convenient for use during fire extinguishing. An activity cover plate 63 is hinged on the fire prevention box 61, which is convenient for replacing the fire extinguisher.
