The housing includes a main body and a fire extinguishing chamber, which can be located in any of the top, side, or bottom walls of the main body. The chamber has a filling hole with a sealing plug. The fire extinguishing chamber is used to hold a fire extinguishing agent. The strength of the side wall of the fire extinguishing chamber closest to the inner cavity of the main body is lower than the strength of the side wall away from the inner cavity. When a battery spontaneously combusts, the fire extinguishing agent in the fire extinguishing chamber expands due to heat, extinguishing the fire in the battery, or the flames extinguish the fire in the fire extinguishing chamber. The side wall of the battery is burned through, and the extinguishing agent overflows to extinguish the fire. The invention provides a box with automatic fire extinguishing function.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 3 , Figure 4 and Figure 5This utility model provides an embodiment of a vehicle chassis fire extinguishing device, comprising a fixed shell 1, a storage compartment 3 on the top of the fixed shell 1, a partition 4 fixedly connected to the inner side of the storage compartment 3 for fixing the partition 4, a plurality of circular holes 5 equidistantly opened on the bottom of the fixed shell 1, each of the circular holes 5 having a fire extinguishing chamber 6 at its upper end for housing the fire extinguishing chamber 6, a top plate 7 slidably connected to the upper middle part of the fixed shell 1, and fixing buckles 8 slidably connected to the left ends of the front and rear sides of the top plate 7, with springs 9 fixedly connected to adjacent sides of two fixing buckles 8. Spring 9 pushes out the fixing buckle 8 to fix the top plate 7. Multiple round holes 5 are equipped with convenient adjustment mechanisms 2 on their inner sides. Multiple convenient adjustment mechanisms 2 are used to fix fire extinguishing chambers 6 of different sizes. The front and rear ends of the right side of the top plate 7 are fixedly connected to fixing rings 10. Pull rings 11 are rotatably connected to the inner sides of the two fixing rings 10. The fixing rings 10 are used to fix the pull rings 11. The outer walls of the two pull rings 11 are fixedly connected to protective sleeves 12. Multiple annular grooves 13 are equidistantly opened on the outer walls of the two protective sleeves 12. The annular grooves 13 are used to increase the friction of the protective sleeves 12.

[0033] Specifically, the partition 4 is fixed into the storage compartment 3. Then, according to the partition on the partition 4, a corresponding number of round holes 5 are made. After multiple round holes 5 are made, the corresponding size fire extinguishing chamber 6 is placed on each round hole 5. Then, the top plate 7 is slid. When the top plate 7 slides to the designated position, two springs 9 will push out the corresponding fixing buckles 8, so that the two fixing buckles 8 are inserted into the corresponding grooves in the storage compartment 3 for fixing. The pull ring 11, which is fixed by the fixing ring 10, makes it easy to pull the top plate 7. The protective sleeve 12 fixed outside the pull ring 11 increases its friction through the ring groove 13 opened on its outside.

[0034] Reference Figure 6 The convenient adjustment mechanism 2 includes a housing 201. The outer walls of multiple housings 201 are fixedly connected to the inner wall of the circular hole 5. Multiple limit buckles 202 are equidistantly slidably connected to the upper inner side of multiple housings 201. The housings 201 are used to install multiple limit buckles 202. Turntables 203 are rotatably connected to the lower inner side of multiple housings 201. Guide grooves 204 are equidistantly opened on the outer walls of multiple turntables 203. The turntables 203 drive the limit buckles 202 to slide through the guide grooves 204. Multiple connecting rods 205 are equidistantly fixedly connected to the bottom of multiple turntables 203. Adjusting rings 206 are fixedly connected to the bottom of multiple connecting rods 205. The adjusting rings 206 drive the turntables 203 to rotate through the connecting rods 205. Rubber sleeves 14 are fixedly connected to the outer walls of multiple adjusting rings 206. Anti-slip textures 15 are opened on the outer walls of multiple rubber sleeves 14. The anti-slip textures 15 are used to improve the anti-slip properties of rubber sleeves 14.

[0035] Specifically, rotating the adjusting ring 206 drives multiple connecting rods 205 to rotate along a trajectory. The rotation of the multiple connecting rods 205 drives the turntable 203 to rotate inside the outer shell 201. While the turntable 203 is rotating, it drives the corresponding limit buckles 202 to slide outward or inward inside the outer shell 201 through multiple guide grooves 204. The rubber sleeve 14 fixed outside the adjusting ring 206 improves its anti-slip properties through the anti-slip texture 15.

[0036] Reference Figure 1 and Figure 2 Fixing plates 16 are fixedly connected to the front, rear, left and right ends of the fixed shell 1. Screws 17 are threaded to the middle of the outer wall of the multiple fixing plates 16. Screws 17 are used to install the fixing plates 16. A display board 18 is installed on the front side of the fixed shell 1. Screws 29 are threaded to the four corners of the front side of the display board 18. Screws 29 are used to fix the display board 18. The outer wall of the fixed shell 1 is provided with rounded corners 20. The rounded corners 20 on the outside of the fixed shell 1 can prevent the vehicle chassis fire extinguishing device from scratching other items.

[0037] Specifically, the mounting shell 1 is fixed by the cooperation of the fixing plate 16 and the screw 17, and the display plate 18 is fixed by the screw 19. The detailed information of the vehicle chassis fire extinguishing device is fixed by the screw 19. The rounded corners 20 on all four sides of the mounting shell 1 reduce friction and prevent scratches.

[0038] Working principle: When manufacturing the vehicle chassis fire extinguishing device, firstly, a storage slot 3 is opened on the fixed shell 1, and then the partition 4 is fixed into the storage slot 3. Then, according to the partition on the partition 4, a corresponding number of round holes 5 are opened. After opening multiple round holes 5, the corresponding size fire extinguishing chamber 6 is placed on each round hole 5. Then, the top plate 7 is slid. When the top plate 7 slides to the designated position, two springs 9 will push out the corresponding fixing buckles 8, so that the two fixing buckles 8 are inserted into the corresponding grooves in the storage slot 3 for fixing. This achieves the effect of dividing the fire extinguishing agent, thereby avoiding the problem of fire extinguishing agent waste.

[0039] When installing fire extinguishing chambers 6 of different sizes on the vehicle chassis fire extinguishing device, firstly, rotate the adjusting ring 206 to drive multiple connecting rods 205 to rotate along the track. The rotation of the multiple connecting rods 205 drives the turntable 203 to rotate inside the outer shell 201. While the turntable 203 is rotating, it will drive the corresponding limit buckles 202 to slide outward or inward inside the outer shell 201 through multiple guide grooves 204 opened on it, thereby achieving the effect of fixing fire extinguishing chambers 6 of different sizes.
