Specific Embodiments

[0035] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0036] Embodiment 1: As Figures 1 to 5 shown, a new energy energy storage battery pack with high safety described in an embodiment of the present invention includes:

[0037] a box body, the box body is composed of an upper box body 1 and a lower box body 2; a group of batteries 3 are evenly distributed inside the box body;

[0038] a protection plate 4, the protection plate 4 is fixedly connected to the lower side of the lower box body 2; the protection plate 4 is provided with a hollow structure, and the inside of the protection plate 4 is filled with buffer liquid;

[0039] a hydraulic sensor 5, the hydraulic sensor 5 is fixedly connected to the surface of the protection plate 4, and the detection end of the hydraulic sensor 5 is located inside the protection plate 4;

[0040] a sealing gasket, the sealing gasket is arranged between the hydraulic sensor 5 and the protection plate 4;

[0041] A controller 7, the controller 7 is fixedly connected to the surface of the protection plate 4, and the hydraulic sensor 5 is electrically connected to the controller 7; the controller 7 can be connected to the car machine of the vehicle;

[0042] A group of cooling pipes 8 are fixedly connected inside the box body, and the cooling pipes 8 are located between adjacent batteries 3; both ends of the cooling pipes 8 extend into the protection plate 4; a circulation pump 9 is fixedly connected inside the protection plate 4, and one end of the cooling pipes 8 is communicated with the circulation pump 9; the circulation pump 9 is a small water pump;

[0043] During the long-term use of the new energy energy storage battery pack, there is an easy problem of excessive surface heat. If heat dissipation is not carried out efficiently in time, there is an easy problem of heat concentration or local thermal runaway on the battery surface, thus affecting the normal working temperature and stability of the battery pack, resulting in potential safety hazards during the long-term use of the battery pack; in the present invention, the buffer liquid inside the protection plate 4 is input into the cooling pipes 8 through the circulation pump 9, and then the buffer liquid flows inside the cooling pipes 8 and takes away the heat generated when the battery 3 works, and then flows back into the protection plate 4 again, forming a liquid path circulation, fully dissipating heat from the battery 3, ensuring a good working state of the battery 3, and improving the safety of the new energy energy storage battery pack;

[0044] At the same time, since the new energy energy storage battery pack is usually installed on the chassis, when the vehicle encounters an uneven road surface or an obstacle during driving, it is easy to cause the bottom of the battery pack to be knocked, damaging the battery 3 inside it, and subsequent spontaneous combustion is likely to occur. Especially for some novice drivers, this knocking process is often difficult to detect, resulting in potential safety hazards during the subsequent use of the battery pack; at this time, in the present invention, by setting the protection plate 4 at the bottom of the box body, the battery pack can be protected, improving the anti-impact ability of the battery pack, and when the protection plate 4 is knocked and causes the protection plate 4 to deform, the pressure of the buffer liquid inside it rises under pressure, and the pressure change is detected by the hydraulic sensor 5, and then the controller 7 sends an alarm signal to the user's car machine, reminding the user to check and repair the battery pack in time, further improving the safety of the battery pack and ensuring the user's life safety.

[0045] The cooling pipes 8 are provided with a plurality of bending parts; by setting the bending parts, the heat exchange area between the cooling pipes 8 and the battery 3 can be increased, the heat exchange path can be extended, and the heat dissipation effect on the battery 3 can be improved.

[0046] A set of heat absorption plates 10 are fixedly connected inside the box body, and the heat absorption plates 10 are located between adjacent batteries 3; the heat absorption plates 10 are made of heat-conducting materials (such as heat-conducting silica gel, heat-conducting silicone grease, etc.); the heat absorption plates 10 correspond to the cooling pipes 8 one by one, and the cooling pipes 8 are inserted inside the heat absorption plates 10; by setting the heat absorption plates 10 to be in direct contact with the batteries 3, the heat absorption plates 10 can quickly absorb heat from the surface of the batteries 3, improve the heat exchange efficiency, and then the buffer liquid in the cooling pipes 8 can fully take away the heat inside them when passing through the heat absorption plates 10, which can further accelerate the heat dissipation speed of the batteries 3.

[0047] A set of rotating rods 11 are rotatably connected inside the cooling pipes 8 through brackets; spiral blades 12 are fixedly connected to the surfaces of the rotating rods 11; by setting the rotating rods 11 and the spiral blades 12, the buffer liquid can push the spiral blades 12 and the rotating rods 11 to rotate when flowing inside the cooling pipes 8, and then the spiral blades 12 prompt the buffer liquid to form a spiral liquid flow, disrupt the motion state of the liquid flow, form a turbulent flow effect, and can improve the heat exchange efficiency between the buffer liquid and the heat absorption plates 10.

[0048] Embodiment 2: As Figures 6 to 9 shown, compared with Embodiment 1, another implementation manner of the present invention is: the buffer liquid stored inside the guard plate 4 is water; an air tank 13 is fixedly connected to the surface of the box body, and compressed gas is stored inside the air tank 13; a set of grooves 14 are opened at the position of the top of the heat absorption plate 10 close to the cooling pipe 8; a connecting ring 15 is arranged between the grooves 14 and the cooling pipe 8; a safety film 16 is fixedly connected inside the connecting ring 15; a support seat 17 is fixedly connected inside the grooves 14; a driving pipe 18 is fixedly connected to the surface of the support seat 17; the driving pipe 18 is communicated with the air tank 13 through a conduit 19 and a solenoid valve 20; a telescopic rod 21 is slidably and sealingly connected inside the driving pipe 18, and a spring 22 is fixedly connected between the telescopic rod 21 and the support seat 17; a thimble 23 is fixedly connected to one end of the telescopic rod 21 close to the safety film 16; a temperature sensor is arranged inside the box body; the temperature sensor and the solenoid valve 20 are both electrically connected to the controller 7; if the battery 3 has a thermal runaway phenomenon and catches fire, the temperature inside the box body rises sharply, the temperature change is detected through the temperature sensor, and then the controller 7 sends an alarm signal to the user's vehicle-mounted computer, and the controller 7 opens the solenoid valve 20, and the compressed gas inside the air tank 13 enters the driving pipe 18 through the conduit 19, pushing the telescopic rod 21 to slide outwards, and then the thimble 23 pierces the safety film 16, and under the pressure generated by the circulation pump 9, the water flow inside the cooling pipe 8 sprays outwards through the connecting ring 15 and the grooves 14 to extinguish the fire on the battery 3, further improving the safety of the battery pack; it is worth noting that most current vehicle-mounted power battery packs use lithium batteries 3, and it is feasible and efficient to extinguish the fire with water.

[0049] A support plate 24 is fixedly connected inside the connecting ring 15, and the support plate 24 is located on the side of the safety film 16 close to the groove 14; a group of through holes 25 are evenly distributed on the surface of the support plate 24, and one of the through holes 25 is aligned with the ejector pin 23 for the ejector pin 23 to pass through and pierce the safety film 16; by arranging the support plate 24 to fit on the surface of the safety film 16, the safety film 16 is supported and protected. When the guard plate 4 is knocked, the water pressure inside the guard plate 4 increases and acts on the surface of the safety film 16 through the cooling pipe 8. At this time, the support plate 24 can provide a supporting force for the safety film 16 to prevent the safety film 16 from being squeezed and broken by the water pressure, so that the water flow will not be ejected in advance.

[0050] A pair of mounting blocks 26 are fixedly connected to the surface of the first driving pipe 18; a connecting rod 27 is fixedly connected to the surface of the mounting block 26; an arc-shaped piece 28 is fixedly connected to one end of the connecting rod 27 close to the first telescopic rod 21; a hook-shaped piece 29 is fixedly connected to the surface of the first telescopic rod 21, and the hook-shaped piece 29 and the arc-shaped piece 28 are buckled with each other; both the hook-shaped piece 29 and the arc-shaped piece 28 are made of elastic materials (such as rubber, elastic metal, etc.); when compressed gas is filled into the first driving pipe 18, since the hook-shaped piece 29 and the arc-shaped piece 28 are buckled with each other, the first telescopic rod 21 will not move immediately, and the gas gradually accumulates pressure inside the first driving pipe 18, and the hook-shaped piece 29 and the arc-shaped piece 28 gradually generate deformation. When the gas pressure is greater than the buckling force between the hook-shaped piece 29 and the arc-shaped piece 28, the hook-shaped piece 29 and the arc-shaped piece 28 are separated from each other. At this time, the first telescopic rod 21 slides out quickly in a short time, which can improve the movement speed and force of the first telescopic rod 21, thereby improving the puncture efficiency of the ejector pin 23 on the safety film 16 and ensuring that the water flow can be ejected smoothly.

[0051] A second driving pipe 30 is fixedly connected to the position inside the guard plate 4 close to the end of the cooling pipe 8; the second driving pipe 30 is communicated with the gas tank 13 through a second conduit 31 and a solenoid valve 20; a second telescopic rod 32 is slidably and sealingly connected inside the second driving pipe 30, and a second spring 33 is fixedly connected between the second telescopic rod 32 and the guard plate 4; a pressing block 34 is fixedly connected to one end of the second telescopic rod 32 close to the cooling pipe 8; when the controller 7 opens the solenoid valve 20, the compressed gas inside the gas tank 13 simultaneously enters the second driving pipe 30 through the second conduit 31, pushing the second telescopic rod 32 to slide outwards, so that the pressing block 34 fits on the end of the cooling pipe 8 and blocks it. Furthermore, the water flow conveyed by the circulation pump 9 into the cooling pipe 8 is sprayed into the box body through the connecting ring 15 and will not flow back to the inside of the guard plate 4 through the other end of the cooling pipe 8, thereby increasing the water supply volume for the fire and further improving the fire extinguishing efficiency.

[0052] One side of the pressing block 34 close to the cooling pipe 8 is fixedly connected with an elastic block 35; by arranging the elastic block 35, the fitting effect between the pressing block 34 and the cooling pipe 8 can be improved, so as to improve the plugging efficiency of the cooling pipe 8 and prevent water leakage.

[0053] Working principle: During normal use, the buffer liquid inside the guard plate 4 is input into the cooling pipe 8 through the circulation pump 9. Then, the buffer liquid flows inside the cooling pipe 8 and takes away the heat generated when the battery 3 works, and then flows back into the guard plate 4 again to form a liquid circuit circulation, so as to fully dissipate the heat of the battery 3 and ensure the good working state of the battery 3.

[0054] At the same time, by arranging the guard plate 4 at the bottom of the box body, the battery pack can be protected and the impact resistance of the battery pack can be improved. And when the guard plate 4 is bumped and deformed, the pressure of the buffer liquid inside it increases after being pressed. The hydraulic sensor 5 detects the pressure change, and then the controller 7 sends an alarm signal to the user's vehicle computer to remind the user to check and repair the battery pack in time, so as to improve the safety of the battery pack and ensure the life safety of the user.

[0055] By arranging the heat absorption plate 10 in direct contact with the battery 3, the heat absorption plate 10 can quickly absorb heat from the surface of the battery 3 to improve the heat exchange efficiency. Then, the buffer liquid in the cooling pipe 8 can fully take away the heat inside it when passing through the heat absorption plate 10, which can further accelerate the heat dissipation speed of the battery 3. By arranging the rotating rod 11 and the spiral blade 12, the buffer liquid can drive the spiral blade 12 and the rotating rod 11 to rotate when flowing inside the cooling pipe 8. Then, the spiral blade 12 promotes the buffer liquid to form a spiral liquid flow, disturbing the movement state of the liquid flow to form a turbulent flow effect, which can improve the heat exchange efficiency between the buffer liquid and the heat absorption plate 10.

[0056] When the battery 3 undergoes a thermal runaway and catches fire, the temperature inside the box rises sharply. The temperature change is detected by the temperature sensor, and then the controller 7 sends an alarm signal to the user's vehicle computer. Meanwhile, the controller 7 opens the solenoid valve 20, and the compressed gas inside the gas tank 13 enters the inside of the driving pipe 18 through the first conduit 19, pushing the first telescopic rod 21 to slide outwards. Then, the ejector pin 23 pierces the safety film 16. Under the pressure generated by the circulation pump 9, the water flow inside the cooling pipe 8 sprays outwards through the connecting ring 15 and the groove 14 to extinguish the fire of the battery 3, further improving the safety of the battery pack. When the compressed gas is filled into the inside of the driving pipe 18, since the hook piece 29 and the arc piece 28 are engaged with each other, the first telescopic rod 21 will not move immediately. The gas gradually accumulates pressure inside the driving pipe 18, causing the hook piece 29 and the arc piece 28 to gradually deform. When the gas pressure is greater than the engagement force between the hook piece 29 and the arc piece 28, the hook piece 29 and the arc piece 28 are separated from each other. At this time, the first telescopic rod 21 slides outwards rapidly in a short time, which can improve the movement speed and force of the first telescopic rod 21, thereby improving the puncture efficiency of the ejector pin 23 on the safety film 16 and ensuring that the water flow can spray out smoothly.

[0057] When the controller 7 opens the solenoid valve 20, the compressed gas inside the gas tank 13 simultaneously enters the inside of the second driving pipe 30 through the second conduit 31, pushing the second telescopic rod 32 to slide outwards, so that the pressing block 34 fits against the end of the cooling pipe 8 and seals it. Then, the water flow transported by the circulation pump 9 into the inside of the cooling pipe 8 all sprays into the box through the connecting ring 15, rather than flowing back into the inside of the guard plate 4 through the other end of the cooling pipe 8, thereby increasing the water supply for the fire and further improving the fire extinguishing efficiency. By setting the elastic block 35, the fitting effect between the pressing block 34 and the cooling pipe 8 can be improved, thereby improving the sealing efficiency of the cooling pipe 8 and preventing water leakage.
