[0003] At present, the traditional new energy vehicle battery anti-spontaneous combustion system usually includes a complex coolant circulation system, which continuously extracts coolant by driving the extraction component and transports it to the cooling pipes around the battery module.

Specifically, although the coolant can absorb and take away some heat during the circulation process, over time, the internal temperature of the coolant will gradually increase, resulting in a decrease in the temperature difference between it and the battery, which not only increases the risk of battery spontaneous combustion, but also reduces the cooling efficiency.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] like Figures 1 to 9As shown, the present application provides a new energy vehicle battery self-ignition prevention system, including a box body 1, a battery assembly 2 is arranged at the bottom end of the box body 1, a sealing cover 3 is arranged at the top end of the box body 1, a heat absorbing plate 4 is fixedly installed inside the sealing cover 3, a cooling box 5 is fixedly installed at the right end inside the sealing cover 3, an extraction assembly 6 is fixedly installed at the left end of the cooling box 5, a cooling pipe 7 is fixedly installed at the water outlet end of the extraction assembly 6, a fixing shell 8 is fixedly installed at the top end of the heat absorbing plate 4, a connecting pipe 9 is fixedly installed at the bottom end of the right side of the fixing shell 8, the other end of the cooling pipe 7 is fixedly connected to the left side of the connecting pipe 9, and the other end of the connecting pipe 9 is fixedly connected to the left side of the cooling box 5;

[0031] The heat dissipation mechanism is arranged inside the fixed shell 8, and includes an impeller 10, which is rotatably connected to the inside of the fixed shell 8, and a transmission wheel 11 located on the outer surface of the fixed shell 8 is fixedly installed at the front end of the impeller 10, and a heat dissipation pipe 12 is fixedly installed on the top of the cooling box 5, and a filter plate 22 located at the rear end of the heat dissipation pipe 12 is fixedly installed at the rear end of the box body 1, and the other end of the heat dissipation pipe 12 is fixedly connected to the rear end of the sealing cover 3, and a support block 13 is fixedly installed inside the heat dissipation pipe 12, and a rotating rod 14 is rotatably connected inside the support block 13, and a fan blade 15 is fixedly installed at the rear end of the rotating rod 14, and a transmission wheel 2 16 is fixedly installed at the front end of the rotating rod 14, and a synchronous belt 17 is connected to the surface of the transmission wheel 11 and the transmission wheel 2 16.

[0032] The operator starts the vehicle, and then the battery assembly 2 can supply power to the entire vehicle. When the battery assembly 2 is working, it will emit heat, and then the heat absorbing plate 4 will absorb the emitted heat, and then the extraction component 6 can be driven to make the cooling pipe 7 extract the coolant inside the cooling box 5, and then the coolant will flow inside the cooling pipe 7. During the flow process, through the principle of cold and heat interaction, the coolant inside the cooling pipe 7 will exchange the heat on the surface of the heat absorbing plate 4, and then the heat absorbing plate 4 and the battery assembly 2 will be cooled, and then the extracted coolant will enter the interior of the fixed shell 8, and then the flowing coolant will drive the impeller 10 to rotate, and then the impeller 10 will drive the transmission wheel 11 to rotate. The second wheel 16 is connected to the transmission with a synchronous belt 17, and when the transmission wheel 11 rotates, the synchronous belt 17 and the second transmission wheel 16 are driven to rotate, and then the second transmission wheel 16 drives the rotating rod 14 and the fan blades 15 to rotate, and then the coolant inside the fixed shell 8 will enter the inside of the connecting pipe 9, so that the coolant will flow back to the inside of the cooling box 5, and then in the rotation process of the fan blades 15, suction will be generated, and then the heat inside the cooling box 5 will be absorbed, and then the absorbed heat will be discharged to the outside of the box body 1, and finally the cooling box 5 is driven to rotate to generate suction, so that the heat in the coolant flowing back to the inside of the cooling box 5 can be effectively absorbed and dissipated into the air, so that the coolant is quickly cooled, thereby ensuring the cooling effect of the coolant.

[0033] like Figure 8 and Fig. 9 As shown, it also includes: a fixing mechanism, which is arranged at the right end of the box body 1, the fixing mechanism includes a socket 25, the socket 25 is arranged at the right end of the box body 1, and a square shell 26 located at the bottom of the socket 25 is fixedly installed on the right end of the box body 1. The bottom end of the inside of the square shell 26 is rotatably connected with a gear 1 27 and a gear 2 28. The front and rear ends of the inside of the square shell 26 are fixedly installed with a limit rod 29, and the surface of the limit rod 29 is slidably connected with a slider 30. The top of the square shell 26 is provided with a square hole 31, and the top of the slider 30 is fixedly installed with a connecting block 1 32 located inside the square hole 31. A clamping plate 33 is fixedly installed on the top of the connecting block 1 32, and a contact block 34 is fixedly installed inside the clamping plate 33. A sliding plate 35 is fixedly installed on the bottom end of the slider 30. The tops of gear 1 27 and gear 2 28 are fixedly installed with sliding blocks 42 located inside the sliding plate 35. An electric push rod 36 is fixedly installed on the left side inside the square shell 26, and a square plate 37 is fixedly installed on the output shaft of the electric push rod 36. Connecting blocks 2 38 are fixedly installed at the front and rear ends of the square plate 37, and a rack 39 meshing with gear 1 27 and gear 2 28 is fixedly installed on the left end of the connecting block 2 38.

[0034] The above scheme is adopted: through the design of the fixing mechanism, after the device is installed inside the car, the plug for powering the car can be inserted into the socket 25, and then the battery assembly 2 can power the entire car. After the plug is inserted, the electric push rod 36 can be driven, and then the output shaft of the electric push rod 36 will push the square plate 37 to move, and then the square plate 37 will drive the connecting block 2 38 and the rack 39 to move. Since the rack 39 rotates with the gear 1 27 and the gear 2 28, when the rack 39 moves, it will drive the gear 1 27 and the gear 2 28 to rotate, and then the gear 1 27 and the gear 2 28 will drive the sliding block 42 to move inside the sliding plate 35. , then the sliding block 42 will push the sliding plate 35 to move relative to each other, and then the sliding plate 35 will drive the slider 30 to move relative to the surface of the limit rod 29, and then the slider 30 will drive the connecting block 32 and the clamping plate 33 to move relative to each other, and then the surface of the contact block 34 will contact the surface of the plug, so that the plug can be fixed to prevent the plug from slipping out of the inside of the socket 25 when the battery assembly 2 is supplying power, thereby causing power interruption or more serious problems, and finally by driving the clamping plate 33 and the contact block 34 to move relative to each other, the risk of the plug slipping out of the inside of the socket 25 when the battery assembly 2 supplies power to the car is effectively reduced, thereby ensuring the stable operation and safety of the car's power system.

[0035] like Figure 5 and Figure 6As shown, a limiting ring 18 located inside the support block 13 is fixedly installed on the surface of the rotating rod 14, and the surface of the limiting ring 18 is in full contact with the inner wall of the support block 13. A barrier cylinder 19 located at the top of the cooling box 5 is fixedly installed at the bottom end of the heat exhaust pipe 12, and the top of the barrier cylinder 19 is of conical design.

[0036] The above scheme is adopted: through the design of the limiting ring 18, when the rotating rod 14 rotates, the rotating rod 14 will drive the limiting ring 18 to rotate inside the support block 13. Since the surface of the limiting ring 18 fits with the inner wall of the support block 13, the rotating rod 14 can be limited to prevent the position of the rotating rod 14 from shifting when it rotates. Through the design of the blocking tube 19, since the blocking tube 19 is provided at the bottom end of the heat exhaust pipe 12, and the blocking tube 19 is conical in design, the coolant inside the cooling box 5 can be blocked from entering the interior of the heat exhaust pipe 12, thereby preventing the coolant from being discharged from the interior of the heat exhaust pipe 12.

[0037] like Figure 2 and Figure 6 As shown, a limiting plate 20 is fixedly installed at the bottom end of the cooling box 5, and a limiting plate 21 is fixedly installed at the top end of the cooling box 5. A gap is provided between the top end of the limiting plate 20 and the top end of the cooling box 5, and a gap is provided between the bottom end of the limiting plate 21 and the bottom end of the cooling box 5. A liquid inlet pipe 23 located inside the sealing cover 3 is fixedly installed at the top end of the cooling box 5, and a sealing plug 24 is provided inside the liquid inlet pipe 23.

[0038] The above scheme is adopted: through the design of the limiting plate 1 20 and the limiting plate 2 21, when the coolant flows back to the interior of the cooling box 5, the limiting plate 1 20 and the limiting plate 2 21 can block the coolant, thereby increasing the flow distance of the coolant, so that the heat inside the coolant can evaporate quickly. Through the design of the liquid inlet pipe 23 and the sealing plug 24, the coolant can be poured into the interior of the liquid inlet pipe 23, and then the coolant will pass through the liquid inlet pipe 23 into the interior of the cooling box 5. After the coolant is added, the sealing plug 24 can be inserted into the interior of the liquid inlet pipe 23, thereby preventing the coolant from flowing out from the interior of the liquid inlet pipe 23.

[0039] like Figure 7 and Figure 8 As shown, support grooves 40 are opened on both sides of the inside of the square hole 31, and a support block 2 41 is slidably connected inside the support groove 40. The support groove 40 is designed to be laterally symmetrical about the center of the connecting block 1 32, and the opposite sides are fixedly connected to the surface of the connecting block 1 32. A connecting shell 43 is fixedly installed on the right side of the square shell 26, and the rack 39 can enter the interior of the connecting shell 43.

[0040] The above scheme is adopted: through the design of the support groove 40 and the support block 2 41, when the connecting block 1 32 moves, the connecting block 1 32 will drive the support block 2 41 to move inside the support groove 40. Since the size of the support block 2 41 is adapted to the size of the support groove 40, the connecting block 1 32 can be supported to ensure the stable movement of the connecting block 1 32. Through the design of the connecting shell 43, when the rack 39 moves, the rack 39 will enter the interior of the connecting shell 43, and the connecting shell 43 can protect the rack 39.

[0041] like Figure 8 As shown, there are multiple contact blocks 34, and an array is distributed inside the clamping plate 33. The contact blocks 34 are made of rubber material, and the surface of the contact blocks 34 is rough. The sliding block 42 is cylindrical, and the surface of the sliding block 42 fits the inner wall of the sliding plate 35.

[0042] The above scheme is adopted: through the design of the contact block 34, since the contact block 34 is made of rubber material and has a rough design, when the contact block 34 contacts the surface of the plug, the friction between the contact block 34 and the plug can be increased, and the contact block 34 is an array design, which can increase the fixing effect of the plug. Through the design of the sliding block 42, since the sliding block 42 is a cylindrical design and fits with the inner wall of the sliding plate 35, it is convenient for the sliding block 42 to move inside the sliding plate 35, thereby increasing the stability of the movement of the sliding plate 35 and the slider 30.

[0043] Working principle and usage process of this application:

[0044] First, the operator can insert the plug used for powering the car into the socket 25, and then the battery assembly 2 can power the entire car. After the plug is inserted into the socket 25, the electric push rod 36 can be driven to make its output shaft push the square plate 37 to move, and then the square plate 37 will drive the connecting block 2 38 and the rack 39 to move, and then the moving rack 39 will drive the gear 1 27 and the gear 2 28 to rotate, and then the gear 1 27 and the gear 2 28 will drive the sliding block 42 to move inside the sliding plate 35, and then the sliding block 42 will push the sliding plate 35 and the slider 30 to move, and then the slider 30 will drive the connecting block 1 32 and the clamping plate 33 to move relative to each other, and then the surface of the contact block 34 will contact the surface of the plug, so that the plug can be fixed to prevent the plug from slipping out of the socket 25;

[0045] In the process of the battery assembly 2 supplying power to the entire vehicle, the surface of the battery assembly 2 will emit heat, and then the heat absorbing plate 4 can absorb the heat emitted by the battery assembly 2, and then the extraction assembly 6 can be driven to make the cooling tube 7 extract the coolant inside the cooling box 5, and then the coolant will flow inside the cooling tube 7, and then through the principle of cold and heat interaction, the coolant inside the cooling tube 7 will exchange the heat on the surface of the heat absorbing plate 4, and then the coolant will enter the interior of the fixed shell 8, and then the flowing coolant will drive the impeller 10 to rotate, and then the impeller 10 will drive the transmission wheel 11 to rotate, and then the transmission wheel 11 will drive the synchronous belt 17 and the transmission wheel 2 16 to rotate, and then the transmission wheel 2 16 will drive the rotating rod 14 and the fan blade 15 to rotate, and then the coolant inside the fixed shell 8 will flow back to the interior of the cooling box 5, and then during the rotation of the fan blade 15, suction will be generated, and then the heat inside the cooling box 5 will be absorbed, and then the absorbed heat will be discharged from the outside of the box body 1, effectively reducing the risk of battery spontaneous combustion, improving the safety performance of new energy vehicles, and finally completing the operation process.
