The side inner wall of the battery compartment mechanism 1 is movably connected to the side inner wall of the battery pack 6, the side of the fixing mechanism 2 is fixedly connected to the side inner wall of the battery compartment mechanism 1, the side of the inflating mechanism 4 is fixedly connected to the side of the battery compartment mechanism 1, the side of the cooling mechanism 5 is fixedly connected to the side of the battery compartment mechanism 1, the side of the conductive mechanism 3 is movably connected to the side inner wall of the battery compartment mechanism 1, and the battery compartment mechanism 1 includes a battery compartment body 101, and the battery compartment body 101 A placement groove 103 is provided at the top of the battery compartment body 101, and the side of the placement groove 103 is movably connected to the side of the battery pack 6. The top of the battery compartment body 101 is fixedly connected to the top cover 102 by bolts. The conductive mechanism 3 is located between the top of the battery pack 6 and the bottom of the top cover 102. The fixing mechanism 2 includes an airbag 203. A mounting groove 105 is provided on the side of the placement groove 103. The side of the mounting groove 105 is fixedly connected to the side of the airbag 203. The inner wall of the side of the airbag 203 is fixedly connected with a clamping plate 201 corresponding to the position of the battery pack 6. The side of the airbag 203 is fixedly connected with a connecting pipe 205. The side of the connecting pipe 205 is connected to the charging mechanism 4. A high-pressure gas cylinder is connected, and a plurality of independent placement grooves 103 are arranged inside the battery compartment body 101. When assembling the battery, the battery pack 6 is placed inside the placement groove 103 to avoid mutual influence of the battery packs 6. The fixing mechanism 2 is located in the middle of the placement groove 103. The fixing mechanism 2 is connected to the high-pressure gas cylinder through the inflation mechanism 4. The high-pressure gas cylinder adopts a 4L specification and is filled with high-pressure carbon dioxide gas. The carbon dioxide gas inside the high-pressure gas cylinder is sent into the airbag 203 through the inflation mechanism 4 and the connecting pipe 205 to expand the airbag 203, thereby pushing the clamping plate 201 to be close to the side of the battery pack 6 to fix the battery pack 6. Then the conductor is The conductive mechanism 3 is installed on the top of the battery pack 6, so that the battery pack 6 is connected in series and connected to the wiring port on the side of the battery compartment body 101. The top cover 102 is fixed to the top of the battery compartment body 101 by bolts, and the conductive mechanism 3 is pressed on the top of the battery pack 6 to further fix the battery pack 6, thereby preventing the battery pack 6 from shaking drastically. At the same time, a certain range of movement is ensured to prevent the battery pack 6 from being damaged by collision due to large vibrations of the car when driving, and the battery compartment mechanism 1 from being damaged by collision. When the airbag 203 is damaged, the carbon dioxide gas inside the airbag 203 leaks, isolating the oxygen around the battery pack 6 to avoid fire.

[0029] Among them, a storage groove 204 is opened on the inner wall of the side of the airbag 203, and the bottom end of the storage groove 204 is fixedly connected to an exhaust column 202, and the top inner wall of the exhaust column 202 is fixedly connected to a pressure spring 206, and the bottom end of the pressure spring 206 is fixedly connected to a sealing piston 207. An air outlet 208 is opened on the side of the exhaust column 202. When the sealing piston 207 moves to above the air outlet 208, the downward pressure exerted by the deformation of the pressure spring 206 on the sealing piston 207 is less than the pressure that the carbon dioxide gas in the high-pressure gas cylinder can exert on the sealing piston 207. When a fire occurs, the internal temperature of the battery compartment main body 101 rises, thereby causing the carbon dioxide gas inside the airbag 203 to expand, increasing the pressure on the sealing piston 207, and the sealing piston 207 moves upward, causing the carbon dioxide gas in the high-pressure gas cylinder to be ejected from the air outlet 208 to isolate the oxygen around the battery pack 6 for extinguishing the fire, thereby avoiding increased losses.

The electronic control valve of the electric control valve 404 adopts the KLD20S miniature reduced-diameter internal and external thread direct-through electric ball valve. When the battery pack 6 needs to be fixed, open the electronic control valve on the electric control valve 404 to allow the high-pressure gas cylinder to enter the airbag 203, and determine the internal pressure value of the airbag 203 through the pressure gauge 405, and then close the electric control valve 404. When in use, the maximum air pressure value and the minimum air pressure value of the pressure gauge 405 are set through the single-chip microcomputer. When the airbag 203 is damaged and leaks, the internal pressure of the airbag 203 is reduced to the minimum value, or when a fire occurs, the internal gas expansion pressure of the airbag 203 increases to the maximum value, and the electronic control valve 404 is controlled to open to allow the carbon dioxide gas of the high-pressure gas cylinder to be ejected.

[0033] The first connecting column 401 has an annular groove 4011 on its side, and the inner wall of the side of the first connecting head 402 has a movable groove 4023 on its side corresponding to the position of the annular groove 4011.

The limiting ball 4021 can move up and down inside the movable groove 4023 and be exposed. When the first connecting head 402 and the first connecting column 401 are assembled, the limiting ring 4022 is pushed along the first connecting head. The surface of 402 slides, so that the limiting ring 4022 moves away from the position of the limiting ball 4021, and the first connecting column 401 is inserted into the first connecting head 402, so that the limiting ball 4021 moves to the outside of the movable groove 4023. When the first connecting column 401 is completely inserted into the first connecting head 402, the limiting ring 4022 is released, and the reset spring 4025 pushes the limiting ring 4022 to move the limiting ring 4022 to the top of the limiting ball 4021. The side inner wall of the limiting ring 4022 contacts the limiting ball 4021, pushing the limiting ball 4021 to be stuck in the annular groove 4011, thereby fixing the first connecting column 401 and the first connecting head 402.

During use, the heat exchange tube inside the battery compartment main body 101 is connected to the automobile cooling device through the cooling mechanism 5, so that the cooling water flows inside the heat exchange tube, and the battery compartment main body 101 is cooled down to prevent the battery pack 6 from being overheated.

[0036] Among them, the clamping plate 201 is made of thermally conductive resin, and the side of the clamping plate 201 contacts the side of the installation groove 105. The heat of the battery pack 6 is transferred to the placement groove 103 through the clamping plate 201 and then transferred to the heat exchange tube for cooling. The pressing plate 301 is made of insulating rubber and has a certain elasticity. The battery pack 6 is pressed into the placement groove 103. The conductive plate 302 is made of conductive copper, which has good conductivity.

[0037] Working principle of the present invention:

[0038] S1. When assembling the battery compartment mechanism 1, place the battery pack 6 into the placement slot 103, insert the conductive plate 302 extending from the side of the pressure plate 301 into the card slot 104 and fix it by connecting it to the internal wiring board, connect the conductive plug 303 to the wiring hole on the top of the battery pack 6 to connect multiple battery packs 6 in series, and connect the battery pack 6 to the wiring port on the side of the battery compartment body 101 through the wiring board, so that the battery pack 6 is connected to other electrical equipment in the car through the wiring port, fix the top cover 102 to the top of the battery compartment body 101 with bolts, press the conductive mechanism 3 on the top of the battery pack 6, and further fix the battery pack 6;

Install the battery compartment mechanism 1 at a specific position on the new energy vehicle, push the limiting ring 4022 to slide along the surface of the first connector 402, so that the limiting ring 4022 moves away from the position of the limiting ball 4021, insert the first connecting column 401 into the first connecting head 402, and move the limiting ball 4021 to the outside of the movable groove 4023. When the first connecting column 401 is fully inserted into the first connecting head 402, loosen the limiting ring 4022, and the reset spring 4025 pushes The limiting collar 4022 moves the limiting collar 4022 to the top of the limiting ball 4021, and the inner wall of the side of the limiting collar 4022 contacts the limiting ball 4021, pushing the limiting ball 4021 to snap into the inside of the annular groove 4011, thereby fixing the first connecting column 401 and the first connecting head 402, so that the fixing mechanism 2 is connected to the high-pressure gas cylinder. Similarly, the heat exchange pipe inside the battery compartment body 101 is connected to the automobile cooling device through the cooling mechanism 5, so that the cooling water flows inside the heat exchange pipe;

[0040] S3. When in use, the maximum and minimum pressure values ​​of the pressure gauge 405 are set by the single chip microcomputer, the electronic control valve on the electronic control valve 404 is opened, and the carbon dioxide gas in the high-pressure gas cylinder is sent into the airbag 203 through the inflation mechanism 4 and the connecting pipe 205, so that the airbag 203 expands, thereby pushing the clamping plate 201 to cling to the side of the battery pack 6 to fix the battery pack 6, until the pressure displayed on the pressure gauge 405 reaches a suitable value, and then the electronic control valve is closed;

[0041] S4. During use, cooling water is allowed to flow inside the heat exchange tube to cool down the battery compartment body 101 to prevent the battery pack 6 from overheating. At the same time, when the airbag 203 is damaged and leaks, the internal pressure of the airbag 203 is reduced to the minimum value, or when a fire occurs, the internal gas expansion pressure of the airbag 203 increases to the maximum value, and the electronic control valve 404 is controlled to open to allow the carbon dioxide gas in the high-pressure gas cylinder to be ejected, thereby increasing the pressure on the sealing piston 207 and moving the sealing piston 207 upward, causing the carbon dioxide gas in the high-pressure gas cylinder to be ejected from the outlet 208, isolating the oxygen around the battery pack 6 to extinguish the fire and avoid increased losses.
