[0004] However, during the use of the above-mentioned technical solutions, since the battery compartment is usually equipped with several battery packs and there are certain gaps between the battery packs, it is difficult for the fire extinguishing agent to be sprayed from a single location to reach the gaps between the battery packs, which can easily lead to insufficient fire extinguishing. In addition, the battery packs are connected by wires, and the ignited wires can spread the flames to other locations, thus causing the fire to spread.

[0005] In other words, existing technologies have the following technical problems: ordinary battery compartment fire suppression structures have difficulty delivering fire extinguishing agents to the gaps in the battery pack, and ignited wires can cause the fire to spread.

[0046] Please see Figure 1 and Figure 2As shown, a car battery compartment with fire and collision alarm functions includes:

[0047] Battery compartment 2, in which battery block 1 is fixedly disposed, and in which partition plate 6 is fixedly disposed, the battery compartment 2 is divided;

[0048] Buffer section 3, which is fixed to the outer wall of battery compartment 2;

[0049] The connecting component 5 is fixedly installed on the side wall of the partition plate 6. The connecting component 5 is used to connect the battery blocks 1 to each other. The connecting component 5 has an automatic cutting function and can automatically cut off under high flame conditions.

[0050] The compartment cover 4 has a fire extinguishing component 9 fixedly connected to its inner side. The fire extinguishing component 9 can automatically release fire extinguishing agent under high temperature flames.

[0051] The above technical solution effectively protects against overheating and fire in some battery blocks 1 under unexpected circumstances. The connecting component 5 connects each battery block 1 and has an automatic disconnect function. In the event of overheating and fire, the connecting wires between battery blocks 1 are automatically disconnected, and the burning wire is automatically extinguished. This effectively prevents the flames from spreading to other battery blocks 1 through the wires, providing good protection. Furthermore, after a fire, the fire extinguishing component 9 automatically releases extinguishing agent inside the battery compartment 2, generating a strong airflow to ensure the extinguishing agent is fully sprayed into the gaps between the battery blocks 1, achieving a more thorough fire extinguishing effect. Simultaneously, an alarm sound is triggered promptly after a fire, effectively alerting personnel.

[0052] For further technical solutions, please refer to Figure 3 , Figure 4 and Figure 5As shown, the connecting component 5 includes a fixed plate frame A501, a fixed plate frame B502, a connector 503, a moving rod 504, a connector base 505, a first connecting wire 508, a second connecting wire 509, a circular shell 510, and a compression spring 511. The fixed plate frame A501 is fixedly installed on the side wall of the partition plate 6, the fixed plate frame B502 is fixedly installed on the side wall of the partition plate 6, and the circular shell 510 is fixedly installed on the side wall of the partition plate 6. The moving rod 504 is slidably connected to the inner cavity of the circular shell 510. A compression spring 511 is fixedly connected between the 4 and the circular shell 510. A power connector 505 is fixedly connected to one end of the moving rod 504. A power connector 503 is fixedly connected to the fixed plate frame B502. The power connector 505 and the power connector 503 are plugged into each other. The power connector 505 is fixedly connected to the moving rod 504. A first connecting wire 508 is connected to the power connector 503. A second connecting wire 509 is connected to the power connector 505. Both the second connecting wire 509 and the first connecting wire 508 are connected to the battery block 1.

[0053] The fixed plate A501 and the connecting plate 506 are fixedly connected by hot melt adhesive 507. Both the fixed plate A501 and the connecting plate 506 are made of metal. The compression spring 511 is in a compressed state. When the battery accidentally catches fire due to high temperature, the high temperature of the flame can be quickly transferred to the fixed plate A501 and the connecting plate 506, causing them to heat up rapidly. This allows the hot melt adhesive 507 between them to melt. After the hot melt adhesive 507 melts, the connecting plate 506... Without the fixation of the hot melt adhesive 507, the compression spring 511 quickly rebounds. The rebounding compression spring 511 drives the moving rod 504 to move, thereby moving the electrical connector 505. This causes the electrical connector 505 to separate from the electrical connector 503, which in turn allows the first connecting wire 508 and the second connecting wire 509 to be cut off. This achieves the function of cutting off the wires, thereby preventing the flame from spreading along the wires to other battery blocks 1, and also disconnecting the current, thus blocking the flame transmission and reducing the spread of the fire.

[0054] A wire fire extinguishing component 7 is provided at the circular shell 510. A piston 512 is slidably connected to the inner cavity of the circular shell 510. The piston 512 is fixedly connected to the moving rod 504. The wire fire extinguishing component 7 includes a bent tube 701, a sponge plug 703, and a nozzle 702. The bent tube 701 is fixed to both sides of the circular shell 510 and communicates with the inner cavity of the circular shell 510. A nozzle 702 is fixedly connected to one end of the bent tube 701. A sponge plug 703 is provided in the inner cavity of the bent tube 701. Dry powder fire extinguishing agent is placed in the inner cavity of the bent tube 701. When part of the battery block 1 catches fire, causing the connected wires to catch fire, the wires can be automatically cut off by triggering the connecting component 5. When the cutting operation is triggered, the moving rod 504 moves rapidly due to the elasticity of the compression spring 511, which pushes the piston 512 to move. The piston 512 moves in the inner cavity of the circular shell 510, which can compress the gas in the inner cavity of the circular shell 510 into the inner cavity of the bent tube 701. The gas then pushes open the sponge plug 703, and the gas carries the dry powder extinguishing agent in the inner cavity of the bent tube 701 and sprays it out from the nozzle 702. The sprayed dry powder extinguishing agent can be released to the second connecting wire 509 and the first connecting wire 508, so as to provide targeted fire extinguishing treatment for the cut wires, thereby extinguishing the fire on the already burning wires and further preventing the spread of flames.

[0055] For a preferred technical solution, please refer to Figure 6 , Figure 7 and Figure 8 As shown, the fire extinguishing component 9 includes a fixed shell 901, a plastic wrapping film 903, and a dry powder extinguishing agent 904. The fixed shell 901 is fixedly installed on the inner wall of the cover 4. Several outlet ports 902 are provided on the outer surface of the fire extinguishing component 9. The plastic wrapping film 903 is provided in the inner cavity of the fixed shell 901, and the inner cavity of the plastic wrapping film 903 is filled with dry powder extinguishing agent 904.

[0056] A rectangular shell 905 is fixedly connected to the bottom surface of the fixed shell 901. A guide slider 906 is slidably connected to the inner cavity of the rectangular shell 905. A rubber cylinder 907 is fixedly installed in the inner cavity of the rectangular shell 905. One end of the rubber cylinder 907 is fixedly connected to the guide slider 906, and the other end of the rubber cylinder 907 is fixedly connected to the inner wall of the rectangular shell 905. A contact slider 908 is slidably connected to the bottom surface of the rectangular shell 905. The contact slider 908 is fixedly connected to the guide slider 906. The rectangular shell 905... A fixed side plate 910 is fixedly connected to one end of the rubber cylinder 907. A return spring 909 is fixedly connected to one end of the side wall of the fixed side plate 910. The other end of the return spring 909 is fixedly connected to the side wall of the contact slider 908. An output pipe 911 is fixedly connected to one end of the inner cavity of the rubber cylinder 907. The other end of the output pipe 911 extends into the inner cavity of the plastic wrapping film 903. An input pipe 912 is fixedly connected to the inner cavity of the rubber cylinder 907. One-way valves are installed on both the output pipe 911 and the input pipe 912. When a fire occurs, the contact slider 908 can be moved by the triggering component 8, which in turn moves the guide slider 906. The movement of the guide slider 906 compresses the rubber cylinder 907, so that the gas in the inner cavity of the rubber cylinder 907 is delivered to the inner cavity of the plastic wrapping film 903 through the output pipe 911.

[0057] For specific technical solutions, please refer to Figure 9 , Figure 10 and Figure 11 As shown, a triggering component 8 is fixedly connected to the inner side of the compartment cover 4. The triggering component 8 includes a circular base 801, a rotating rod 802, a disc 804, a rotating arm 805, a burn-off section 806, and a striking hammer section 807. The circular base 801 is fixedly disposed on the inner side of the compartment cover 4. The rotating rod 802 is rotatably connected to the inner cavity of the circular base 801. One end of the rotating rod 802 extends to the outside of the wall of the circular base 801. The disc 804 is fixedly connected to one end of the rotating rod 802. Rotating arms 805 are fixedly connected to both sides of the disc 804. A striking hammer section 807 is fixedly connected to both rotating arms 805. One end of the burn-off section 806 is fixedly connected to one end of the disc 804. The other end of the burn-off section 806 is fixedly connected to the compartment cover 4. A rotating energy storage section 803 is fixedly connected between the circular base 801 and the rotating rod 802.

[0058] The rotating energy storage part 803 is a spring-loaded spring, and the rotating energy storage part 803 is in a wound state. The burn-off part 806 is a nylon rope.

[0059] When a battery catches fire, the high temperature of the flame will quickly extinguish the flame-cutting part 806. Without the limiting effect of the flame-cutting part 806, and with the rotating energy storage part 803 in a loaded energy storage state, the rotating rod 802 can rotate rapidly, which in turn drives the disc 804 to rotate, and consequently the two rotating arms 805 to rotate. The rotation of the rotating arms 805 causes the front hammer part 807 to continuously collide with the contact slider 908. Upon collision with the contact slider 908, the guide slider 906 is pushed to move, causing the rubber air cylinder 907 to compress, thus allowing gas to enter the inner cavity of the plastic wrapping film 903. Due to the continuous rotation of the rotating arms 805... This causes the hammer 807 to continuously strike and push the contact slider 908 to move, thereby continuously inflating the inside of the plastic wrapping film 903. As the plastic wrapping film 903 is continuously inflated, the internal pressure increases. When it reaches its limit, the plastic wrapping film 903 breaks, and the gas is released instantly, generating a strong airflow that carries the internal dry powder extinguishing agent 904 out rapidly. The strong airflow allows the dry powder extinguishing agent 904 to be fully sprayed at various positions and gaps of the battery block 1, achieving a more effective fire extinguishing effect. The strong airflow also allows the extinguishing agent to be sprayed into the gaps, avoiding the problem of reduced fire extinguishing efficiency caused by the difficulty in releasing the extinguishing agent in the gaps.

[0060] The hammer part 807 includes a connecting post 8071, a hammer head 8072, a round head 8073, a spring 8074, and a metal rattle plate 8075. The connecting post 8071 is fixedly disposed at one end of the rotating arm 805. The hammer head 8072 is provided with an inner cavity. The connecting post 8071 and the inner cavity of the hammer head 8072 are slidably fitted. The spring 8074 is fixedly connected between the connecting post 8071 and the hammer head 8072. The round head 8073 is fixedly connected to one end of the connecting post 8071. The metal rattle plate 8075 is fixedly connected to the inner cavity of the hammer head 8072.

[0061] When the triggering component 8 is triggered by the flame, the rotating arm 805 can rotate continuously for a period of time. Due to the rotation of the rotating arm 805, the hammer part 807 can continuously contact and collide with the contact slider 908. When the hammer head 8072 contacts the contact slider 908, due to the pressing action, the connecting column 8071 moves and drives the round head 8073 to strike the metal rattle plate 8075, thereby making the metal rattle plate 8075 produce a sound. Through the above process, after the flame is triggered, an audible alarm can be continuously generated for a period of time, which plays an automatic alarm function and can play an automatic warning effect, reminding the staff to deal with it in time.

[0062] The buffer part 3 is a rubber strip. By setting the buffer part 3, it can play a role in buffering and protecting the object after an impact.

[0063] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
