DETAILED DESCRIPTION

[0023] like Figure 1-Figure 3As shown, the utility model provides a technical solution: a heat-insulating and flame-retardant battery box, including a box body 1, the box body 1 is hinged with a box door 2, the inner wall of the box body 1 is provided with a flame-retardant component, and the flame-retardant component includes a partition 3, an elastic member 4, a limit frame 5, an arc-shaped spring piece 6, a splint 7, a fire extinguisher 8, a pressure handle 9, an elastic ring 10, a safety pin 11, an elastic rope 12, a pull rope 13, a nozzle 14, a fire baffle 15, and a one-way valve 16.

[0024] In one embodiment of the utility model, the inner wall of the box body 1 is fixedly connected with a partition 3, the inner wall of the box body 1 is fixedly connected with an elastic member 4, the end of the elastic member 4 away from the inner wall of the box body 1 is fixedly connected with a limit frame 5, and the number of limit frames 5 is provided in two groups, one of which is fixedly connected to the elastic member 4, and the other is fixedly connected to the side wall of the partition 3. The limit frame 5 is sleeved with the fire baffle 15, and the inner wall of the limit frame 5 is fixedly connected with an arc spring piece 6, which is fixedly connected to the splint 7. The top end surface of the partition 3 is fixedly connected with a fire extinguisher 8, and the fire extinguisher 8 is connected to the spray The nozzle 14 is fixedly connected, and the end of the nozzle 14 away from the fire extinguisher 8 passes through the bottom end surface of the partition 3. The end surface of the fire extinguisher 8 is provided with a pressure handle 9, and the side wall of the pressure handle 9 is sleeved with an elastic ring 10, which abuts against the lifting handle. The elastic ring 10 pulls the pressure handle 9 toward the lifting handle, thereby triggering the fire extinguisher 8. The fire extinguisher 8 is plugged into the safety pin 11, and the safety pin 11 abuts against the elastic rope 12. The other end of the safety pin 11 is fixedly connected to the pull rope 13, and the other end of the pull rope 13 is fixedly connected to the inner wall of the box body 1. The inner wall of the box door 2 is fixedly connected with a one-way valve 16, and the air is discharged through the one-way valve 16.

[0025] The battery panel is inserted between the two groups of limit frames 5. Under the elastic action of the elastic member 4 and the arc-shaped spring sheet 6, the battery panel is limited, so that the battery box can adapt to battery panels of different sizes. At the same time, the gaps between the battery panels are convenient for heat dissipation of the battery panels, so as to prevent the heat inside the battery panels from being unable to dissipate, resulting in an increase in battery temperature, and then causing thermal runaway. When the battery burns, the pull rope 13 will melt, and then the elastic rope 12 can pull the safety pin 11 to pull out the safety pin 11. Under the elastic action of the elastic ring 10, the pressure handle 9 is pulled toward the lifting handle, thereby triggering the fire extinguisher 8. The carbon dioxide inside the fire extinguisher 8 is sprayed into the box body 1 through the nozzle 14. Due to the heavy weight of the carbon dioxide, the lighter air is discharged from the box body 1 through the one-way valve 16. The carbon dioxide cuts off the oxygen required for battery combustion, thereby extinguishing the flame and improving the safety of the battery box.

[0026] In addition, the limit frame 5 is connected with the fire baffle 15. When the two sets of limit frames 5 move relative to each other, the fire baffle 15 always isolates the batteries to prevent the battery fire from causing fire in surrounding batteries, reduce the spread of the fire, and improve safety.

[0027] In the utility model, when in use, the limit frame 5 and the clamping plate 7 fix the battery under the elastic push of the elastic member 4 and the arc-shaped spring piece 6, so that the battery box can adapt to batteries of different sizes. At the same time, gaps are left between the batteries to avoid heat accumulation inside the battery panel and thermal runaway. When the battery burns, the fire extinguisher 8 is triggered, and the carbon dioxide inside the fire extinguisher 8 is sprayed into the box body 1 through the nozzle 14. The lighter air is discharged through the one-way valve 16, so that only carbon dioxide exists in the box body 1, thereby cutting off the oxygen required for battery combustion and extinguishing the flame. Furthermore, when the two sets of limit frames 5 move relative to each other, the fire baffle 15 always isolates the battery to prevent the battery fire from causing the surrounding batteries to catch fire, thereby reducing the spread of the fire.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
