[0007] The storage battery is installed in a fixed frame, and the cover plate presses on the top of the storage battery. The storage battery is fixedly installed in the fixed frame through a locking pull rod. The safety buffer airbag in the fixed frame can, on the one hand, play a good buffering role for the storage battery, avoiding collision between the storage battery and the fixed frame and damaging the storage battery. On the other hand, the carbon dioxide gas filled in the safety buffer airbag is released after the storage battery catches fire, playing a good flame retardant role.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0021] As Figures 1-3 shown, an automotive battery support assembly includes a tray 100, a cover plate 200, a fixed frame 300 and a locking pull rod 400. The fixed frame 300 is arranged on the tray 100, the cover plate 200 is located above the fixed frame 300, and both ends of the locking pull rod 400 are respectively connected to the tray 100 and the cover plate 200; A safety buffer airbag 301 is arranged in the fixed frame 300. The safety buffer airbag 301 is filled with carbon dioxide gas. An airbag box 201 is arranged on the top of the cover plate 200, and an airbag that can cover the fixed frame 300 after inflation is arranged in the airbag box 201.
[0022] In this embodiment, the safety airbag 301 is preferably filled with carbon dioxide gas, which has low cost and good flame retardant effect. Of course, other flame retardant gases such as nitrogen and argon can also be selected. When the storage battery catches fire, first, the airbag in the airbag box 200 is ejected to cover the storage battery to isolate air and prevent surrounding substances from being ignited. Then, the gas in the safety airbag 301 is released to reduce the internal oxygen concentration and achieve the effect of flame retardant and fire extinguishing.
[0023] Among them, the safety airbag 301 is disposed close to the inner wall of the fixed frame 300, and a plurality of electromagnetic ejector pins 302 are provided in the side plate of the fixed frame 300. After detecting that the storage battery catches fire, the electromagnetic ejector pins 302 are controlled to eject the ejector pins at their ends to pierce the safety airbag 301 and release the flame retardant gas therein.
[0024] Particularly, the airbag in the airbag box 201 is connected to an airbag gas generator. A buckle plate 202 is provided at the top of the airbag box 201. One side of the buckle plate 202 is rotatably connected to the airbag box 201, and the other side is connected to the airbag box 201 through a snap fastener.
[0025] Preferably, locking lug ears 101 are provided on both sides of the tray 100. One end of the locking pull rod 400 is provided with an external thread, and the other end is provided with a hook 401. The hook 401 is connected to the locking lug ear 101. Through holes are provided at both ends of the cover plate 200. The end of the locking pull rod 400 with the external thread passes through the through hole and is connected to the cover plate 200 through a bolt. The cover plate 200 is a bent part, and a fixed angle iron 203 is provided at its bent part.
[0026] A temperature sensor 303 and an ionic flame sensor 304 are provided on the inner wall of the fixed frame 300. The number of the temperature sensor 303 and the ionic flame sensor 304 is multiple and they are distributed in an array on the fixed frame 300.
[0027] In this embodiment, the temperature of the storage battery is monitored by the temperature sensor 303. When there is a flame, the gas molecules in the flame will be excited into ions, and a small current will be introduced into two electrodes of the ionic flame sensor 304. The ions generated by the flame will increase the current. By monitoring the change of the current, it can be judged whether there is a flame and corresponding control actions can be triggered. In addition, an ultraviolet flame sensor, a composite flame sensor, etc. can also be selected to achieve this.
[0028] Both the safety airbag 301 and the outer part of the airbag in the airbag box 201 are provided with ceramic fiber cloth. Ceramic fiber cloth: The continuous use temperature can reach 1000 °C, the short-term use temperature can reach 1260 °C, and it can even withstand high temperatures up to 1500 °C. It can remain stable at high temperatures of 1000 - 1300 °C, is not easy to conduct heat, has extremely strong heat resistance, has an extremely high melting point, can effectively play a flame retardant role, and at the same time it also has excellent properties such as being non-toxic, harmless, odorless, and having no adverse effects on the environment.
[0029] A cooling pipeline 305 is provided in the fixed frame 300. The cooling pipeline 305 is connected to a spray head 306, and the spray head 306 is arranged on the inner wall of the fixed frame 300.
[0030] The cooling medium in the cooling pipeline 305 includes hydrocarbon surfactants, fluorocarbon surfactants, flame retardants, and additives. The molecule of the hydrocarbon surfactant consists of two parts: hydrophilic and lipophilic, which helps the fire extinguishing agent form an isolation between the fire source and the air, quickly containing the fire; the fluorocarbon surfactant enhances the cooling effect of the fire extinguishing agent. Through its special physical properties, it can reduce the temperature of the fire source in a short time, creating conditions for fire extinguishing. The flame retardant reduces the burning speed of combustible substances through chemical reactions, ensuring that the fire source is effectively controlled. The existence of the additive is to assist the above components to better play their functions, thereby enhancing the overall fire extinguishing effect.
[0031] The working principle of an automotive battery support assembly provided by the present invention is as follows: The battery is installed in the fixed frame 300 and is fixedly installed through the cover plate 200. The temperature of the battery is monitored by the temperature sensor 303. When the battery is abnormally hot, the temperature sensor 303 sends information to the vehicle control system. The vehicle alarms and pumps the cooling medium through the cooling pipeline 305 and the spray head 306 to the battery to cool it down to avoid catching fire. When the battery catches fire, the temperature sensor 303 detects the abnormally high temperature and the flame monitored by the ionic flame sensor 304, and sends information to the vehicle control system. The control system of the vehicle sends an instruction to make the airbag gas generator inflate the airbag in the airbag box 201, so that the airbag ejects and covers the battery in an extremely short time, isolating the air and controlling the fire. At the same time, it avoids igniting surrounding substances and intensifying the fire. Then the electromagnetic ejector pin 302 pierces the safety airbag 301 to release carbon dioxide gas, and the cooling pipeline 305 sprays the cooling medium on the battery. The combination of these three means can effectively deal with small fires and can also provide enough time for personnel to escape when the battery burns violently.
[0032] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements can be made, and these improvements should also be regarded as the protection scope of the present invention.
