[0015] A method for using a control device for an automotive hybrid system according to any one of claims 1-9, comprising the following steps: First step: Install the integrated control box body to ensure the normal use of the integrated control box body. A connecting plate is arranged on the outer wall of the top of the integrated control box body, a docking groove is formed in the connecting plate, docking plates are arranged on the left and right sides of the box cover, and a clamping block is arranged on the lower surface of the docking plate. The size of the clamping block matches the size of the docking groove. Therefore, the box cover and the integrated control box body can be disassembled and assembled through the mutual clamping of the clamping block and the docking groove, so as to facilitate the maintenance of the parts inside the integrated control box body. A vehicle controller, an engine, an engine controller, a clutch, a permanent magnet synchronous motor, a motor controller, a battery management system, a battery pack, and a transmission are arranged inside the integrated control box body. The engine is electrically connected to the engine controller, the permanent magnet synchronous motor is electrically connected to the motor controller, the battery pack supplies power to the battery management system, the battery management system is electrically connected to the motor controller, and the clutch and the transmission are both controlled by the vehicle controller. Therefore, the normal use of the hybrid system can be ensured. The coordinated use of the vehicle controller, the engine controller, and the motor controller can realize the adjustment of the driving mode of the vehicle. When the remaining power of the battery pack is higher than the set value, the engine operates and the clutch is disengaged. At this time, the permanent magnet synchronous motor operates and transmits power to the transmission. The power is transmitted to the end shaft through the transmission, and the vehicle travels in pure electric mode. When the remaining power of the battery is lower than the set value, the motor controller controls the permanent magnet synchronous motor not to operate and engages the clutch. At this time, the engine is used as a starting motor, and the power of the engine is transmitted through the clutch and the transmission, enabling the transmission to obtain power. Then, the power is transmitted to the end shaft through the transmission to drive the vehicle to travel, and the vehicle travels in engine direct drive mode; Step 2: Cool the inside of the integrated control box Since metal collars are installed on the outer walls of both the engine and the permanent magnet synchronous motor, when the engine and the permanent magnet synchronous motor are in use, the heat on the engine and the permanent magnet synchronous motor will be transferred to the collars. The collars are connected to the metal plate through heat conducting rods, so the heat on the collars can be transferred to the metal plate through the heat conducting rods. The metal plate is installed on the sealed box body, so the heat will enter the sealed box body, causing the air inside the sealed box body to expand due to heat. As a result, the fixed plate moves upward. When the fixed plate rises, it will squeeze the first spring. Under the action of the guide rod, the fixed plate will move more smoothly when moving. As the fixed plate rises, the air will be pushed into the exhaust pipe. There is a baffle inside the exhaust pipe, and through holes are opened on the baffle. Therefore, the gas will flow through the through holes, which will push the connecting block, causing the connecting block to drive the positioning rod to move together. When the positioning rod moves, it will drive the limiting block to move and squeeze the second spring; After the connecting block is pushed, it will separate from the exhaust pipe and then contact the micro switch to turn on the micro switch. After the micro switch is turned on, the fan will start to operate. The inlet end of the fan is connected to the air inlet pipe, and a first shunt pipe is installed on the air inlet pipe. The first shunt pipe is provided with air inlets, so the hot gas inside the integrated control box can be adsorbed through the air inlets and then discharged outward through the exhaust pipe. This can accelerate the flow rate of the gas inside the integrated control box, thereby achieving the purpose of cooling the inside of the integrated control box; Step 3: Cool the inside of the integrated control box again On the outer wall bearing of the integrated control box body, a rotating rod is connected. And on the outer wall of the rotating rod, connecting blades are installed. And the connecting blades and the outlet end of the exhaust pipe are on the same horizontal line. So when the exhaust pipe discharges gas, it will drive the connecting blades to rotate, thereby driving the rotating rod to rotate. On the outer wall of the rotating rod, a cam is also installed. So the cam will rotate. When the cam rotates and squeezes the airbag, the gas inside the airbag will be transported through the conveying pipe to the second shunt pipe. The second shunt pipe is located inside the integrated control box body. Therefore, it can blow air inside the integrated control box body to achieve the purpose of cooling again. Among them, one-way valves are installed at the inlet of the airbag and on the second shunt pipe. So when the airbag resets and inhales, the second shunt pipe will not inhale, ensuring the normal progress of the re-cooling work.

[0016] Compared with the prior art, the beneficial effects of the present invention are: For this automotive hybrid system control device and its usage method, through the heat dissipation structure, the inside of the integrated control box body during use is cooled and dissipated, effectively preventing the phenomenon of excessive internal temperature and reducing the damage probability of parts, as shown in the following content: (1) The heat dissipation structure includes collars installed on the outer walls of the engine and the permanent magnet synchronous motor. One end of the collar is connected to one end of the heat conducting rod, and the other end of the heat conducting rod is connected to the metal plate. And the metal plate is installed on the sealed box body. At the same time, the collar is made of metal. In this way, the heat generated when the engine and the permanent magnet synchronous motor work can be transferred through the heat conducting rod and the metal plate, and the heat enters the sealed box body; Further, a fixing plate is arranged inside the sealed box body. And a first spring is installed between the upper surface of the fixing plate and the top of the sealed box body. And a guiding rod penetrates through the inner wall of the fixing plate. In this way, under the action of the guiding rod, the fixing plate can move more smoothly, preventing the phenomenon of shaking; Further, an exhaust pipe is installed on the sealed box body. And a baffle is arranged inside the exhaust pipe. And a positioning rod penetrates through the baffle. One end of the positioning rod is connected to the limiting block, and the other end of the positioning rod is connected to the connecting block. And a second spring is installed between the limiting block and the baffle. At the same time, through holes are opened on the baffle. In this way, the gas inside the sealed box body can be pushed into the exhaust pipe, thereby pushing the connecting block to move; Even further, after the connecting block moves a certain distance, it will contact the microswitch, and then turn on the microswitch, causing the microswitch to start the fan. The inlet end of the fan is connected to the air inlet pipe. A first shunt pipe is installed on the air inlet pipe. And an air inlet is arranged on the lower surface of the first shunt pipe. Thus, the heat inside the integrated control box body can be adsorbed, and then discharged out through the exhaust pipe, accelerating the circulation of the hot gas inside the integrated control box body; (2) A rotating rod is installed on the outer wall of the integrated control box body, and a connecting blade is installed on the rotating rod. The connecting blade and the outlet end of the exhaust pipe are on the same horizontal line. When the exhaust pipe discharges air, it will drive the connecting blade to rotate, and then drive the rotating rod to rotate together. The rotating rod will drive the cam to rotate, squeeze the airbag, and convey the gas into the integrated control box body through the second shunt pipe on the conveying pipe, so as to achieve the purpose of cooling the integrated control box body again.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0020] In this embodiment, the normal use of the integrated control box 1 is disclosed, and different driving modes can be switched, specifically as Figures 1 - 4 shown below: A docking groove 3 is formed on the connecting plate 2. The upper surface of the integrated control box 1 is attached with a box cover 4. Docking plates 5 are installed on both the left and right sides of the box cover 4. A clamping block 6 is arranged on the lower surface of the docking plate 5. Inside the integrated control box 1, there are a vehicle controller 7, an engine 8, an engine controller 9, a clutch 10, a permanent magnet synchronous motor 11, a motor controller 12, a battery management system 13, a battery pack 14, and a transmission 15. A terminal shaft is installed at the output end of the transmission 15. The clamping block 6 and the docking plate 5 are of an integral structure, and the size of the clamping block 6 matches the size of the docking groove 3. The connecting plate 2 and the integrated control box 1 are connected by welding. A connecting plate 2 is arranged on the outer wall of the top of the integrated control box 1. A docking groove 3 is formed on the connecting plate 2. Docking plates 5 are arranged on both the left and right sides of the box cover 4. A clamping block 6 is arranged on the lower surface of the docking plate 5. The size of the clamping block 6 matches the size of the docking groove 3. Therefore, the box cover 4 and the integrated control box 1 can be disassembled and assembled through the mutual clamping of the clamping block 6 and the docking groove 3, so as to facilitate the maintenance of the parts inside the integrated control box 1. Inside the integrated control box 1, there are a vehicle controller 7, an engine 8, an engine controller 9, a clutch 10, a permanent magnet synchronous motor 11, a motor controller 12, a battery management system 13, a battery pack 14, and a transmission 15. The engine 8 and the engine controller 9 are electrically connected. The permanent magnet synchronous motor 11 and the motor controller 12 are electrically connected. The battery pack 14 supplies power to the battery management system 13. The battery management system 13 and the motor controller 12 are electrically connected. The clutch 10 and the transmission 15 are both controlled by the vehicle controller 7. Therefore, the normal use of the hybrid power system can be ensured. The coordinated use of the vehicle controller 7, the engine controller 9, and the motor controller 12 can realize the adjustment of the vehicle driving mode. When the remaining power of the battery pack 14 is higher than the set value, the engine 8 operates and the clutch 10 is disengaged. At this time, the permanent magnet synchronous motor 11 operates and transmits power to the transmission 15. After passing through the transmission 15, the power is transmitted to the end shaft. At this time, the vehicle travels in pure electric mode. When the remaining power of the battery is lower than the set value, the motor controller 12 controls the permanent magnet synchronous motor 11 not to operate and engages the clutch 10. At this time, the engine 8 is used as a starting motor, and the power of the engine 8 is transmitted through the clutch 10 and the transmission 15, so that the transmission 15 can obtain power. Then the power is transmitted through the transmission 15 to the end shaft to drive the vehicle to travel. At this time, the vehicle travels in the engine 8 direct drive mode. Embodiment 2

[0021] In this embodiment, a heat dissipation structure is disclosed. When the integrated control box 1 is in use, it can cool and dissipate heat inside it, effectively preventing the phenomenon of overheating. Specifically, as Figures 6 - 8 and Figure 10 shown: A heat dissipation structure that can accelerate the heat dissipation process is provided outside the engine 8 and the permanent magnet synchronous motor 11. The heat dissipation structure includes a collar 16 installed on the outer walls of the engine 8 and the permanent magnet synchronous motor 11. One end of the outer wall of the collar 16 is connected to one end of a heat conducting rod 17, and the other end of the heat conducting rod 17 is connected to a metal plate 18. The metal plate 18 is installed on the sealed box body 19. At the same time, the collar 16 is made of metal. A fixing plate 20 is provided inside the sealed box body 19, and a first spring 21 is installed between the upper surface of the fixing plate 20 and the top of the sealed box body 19. A guiding rod 22 penetrates through the inner wall of the fixing plate 20; A sealing ring for sealing is provided at the outer edge of the fixing plate 20, and the fixing plate 20 is slidably connected to the guiding rod 22. An exhaust pipe 23 is installed on the sealed box body 19. A baffle 24 is provided inside the exhaust pipe 23. A positioning rod 25 penetrates through the baffle 24. One end of the positioning rod 25 is connected to a limiting block 26, and the other end of the positioning rod 25 is connected to a connecting block 28. A second spring 27 is installed between the limiting block 26 and the baffle 24. At the same time, through holes 29 are provided on the baffle 24; The baffle 24 is welded to the inner wall of the exhaust pipe 23. The through holes 29 on the baffle 24 are equally angularly distributed, and the baffle 24 is slidably connected to the positioning rod 25. A micro switch 30 is provided on the side of the exhaust pipe 23 away from the sealed box body 19. The micro switch 30 is installed on the lower surface of the top plate 31, and the top plate 31 is fixed to the inner wall of the integrated control box 1 through a mounting rod 43; Since collar rings 16 made of metal are installed on the outer walls of both the engine 8 and the permanent magnet synchronous motor 11, when the engine 8 and the permanent magnet synchronous motor 11 are in use, the heat on the engine 8 and the permanent magnet synchronous motor 11 will be transferred to the collar rings 16. The collar rings 16 are connected to the metal plate 18 through heat conduction rods 17. Therefore, the heat on the collar rings 16 can be transferred to the metal plate 18 through the heat conduction rods 17. The metal plate 18 is installed on the sealed box body 19. So, the heat will enter the sealed box body 19, causing the air inside the sealed box body 19 to expand due to heat. As a result, the fixed plate 20 moves upward. When the fixed plate 20 rises, it will squeeze the first spring 21. Under the action of the guide rod 22, the fixed plate 20 will move more smoothly when moving. As the fixed plate 20 rises, the air will be pushed into the exhaust pipe 23. A baffle 24 is provided inside the exhaust pipe 23, and through holes 29 are provided on the baffle 24. Therefore, the gas will flow through the through holes 29, which will then push the connecting block 28, causing the connecting block 28 to drive the positioning rod 25 to move together. When the positioning rod 25 moves, it will drive the limiting block 26 to move and squeeze the second spring 27; After the connecting block 28 is pushed, it will separate from the exhaust pipe 23 and then contact the micro switch 30, turning on the micro switch 30. After the micro switch 30 is turned on, the fan 32 will start working. The inlet end of the fan 32 is connected to the air inlet pipe 33, and a first shunt pipe 34 is installed on the air inlet pipe 33. An air inlet 35 is provided on the first shunt pipe 34. Therefore, the hot gas inside the integrated control box body 1 can be adsorbed through the air inlet 35 and then discharged outward through the exhaust pipe 36. This can accelerate the flow rate of the gas inside the integrated control box body 1, thereby achieving the purpose of dissipating heat inside the integrated control box body 1.

[0022] Embodiment 3: In this embodiment, a reheat dissipation structure is disclosed to further accelerate the air flow rate inside the integrated control box body 1. For details, please refer to Figure 5 and Figure 9 : A fan 32 is also installed inside the integrated control box body 1. The inlet end of the fan 32 is installed with an air inlet pipe 33, and a first shunt pipe 34 is provided on the air inlet pipe 33. At the same time, an air inlet 35 is provided at the bottom of the first shunt pipe 34. The outlet end of the fan 32 is installed with an exhaust pipe 36; A rotating rod 37 is installed on the outer wall of the integrated control box body 1, and a connecting blade 38 is installed on the rotating rod 37. The connecting blade 38 and the outlet end of the exhaust pipe 36 are on the same horizontal line. A cam 39 is also installed on the rotating rod 37, and the cam 39 is located in front of the connecting blade 38. An airbag 40 is provided on the left side of the cam 39. The outlet end of the airbag 40 is installed with a delivery pipe 41, and a second shunt pipe 42 is provided on the delivery pipe 41. Check valves are installed at both the air inlet of the airbag 40 and the second shunt pipe 42.

[0023] On the outer wall bearing of the integrated control box body 1, a rotating rod 37 is connected. And on the outer wall of the rotating rod 37, a connecting blade 38 is installed. And the connecting blade 38 and the outlet end of the exhaust duct 36 are on the same horizontal line. So when the exhaust duct 36 discharges gas, it will drive the connecting blade 38 to rotate, thereby driving the rotating rod 37 to rotate. On the outer wall of the rotating rod 37, a cam 39 is also installed. So the cam 39 will rotate. When the cam 39 rotates and squeezes the airbag 40, the gas inside the airbag 40 will be transported through the delivery pipe 41 to the second shunt pipe 42. The second shunt pipe 42 is located inside the integrated control box body 1. Therefore, the inside of the integrated control box body 1 can be blown with air to achieve the purpose of cooling again. Wherein, one-way valves are installed at the inlet of the airbag 40 and on the second shunt pipe 42. So when the airbag 40 resets and inhales, the second shunt pipe 42 will not inhale, ensuring the normal progress of the re-cooling work.

10. A method for using a vehicle hybrid power system control device according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: Install the integrated control box (1) to ensure the normal use of the integrated control box (1). A connecting plate (2) is provided on the top outer wall of the integrated control box (1), and a docking groove (3) is provided on the connecting plate (2). A docking plate (5) is provided on both the left and right sides of the box cover (4), and a clamping block (6) is provided on the lower surface of the docking plate (5). The size of the clamping block (6) matches the size of the docking groove (3). Therefore, the box cover (4) and the integrated control box (1) can be disassembled and assembled by mutually engaging the clamping block (6) and the docking groove (3), thereby facilitating the inspection and repair of the parts inside the integrated control box (1). A vehicle controller (7), an engine (8), an engine controller (9), a clutch (10), and a permanent magnet synchronous motor (11) are provided inside the integrated control box (1). , a motor controller (12), a battery management system (13), a battery pack (14) and a transmission (15), and the engine (8) and the engine controller (9) are electrically connected by signals, the permanent magnet synchronous motor (11) and the motor controller (12) are electrically connected by signals, and the battery pack (14) supplies power to the battery management system (13), the battery management system (13) and the motor controller (12) are electrically connected by signals, and the clutch (10) and the transmission (15) are both controlled by the vehicle controller (7), so that the normal use of the hybrid power system can be guaranteed, and the coordinated use of the vehicle controller (7), the engine controller (9) and the motor controller (12) can realize the adjustment of the vehicle driving mode; When the remaining power of the battery pack (14) is higher than the set value, the engine (8) operates and the clutch (10) is disconnected. At this time, the permanent magnet synchronous motor (11) operates and transmits power to the transmission (15), and the power is transmitted to the end shaft through the transmission (15). At this time, the vehicle travels in a pure electric mode. When the remaining power of the battery is lower than the set value, the motor controller (12) controls the permanent magnet synchronous motor (11) not to operate and causes the clutch (10) to engage. At this time, the engine (8) is used as a starter motor. The power of the engine (8) is transmitted through the clutch (10) and the transmission (15), so that the transmission (15) can obtain power. Then, the power is transmitted to the end shaft through the transmission (15) to drive the vehicle to travel. At this time, the vehicle travels in a direct drive mode of the engine (8); Step 2: Cooling the interior of the integrated control box (1) Since the outer walls of the engine (8) and the permanent magnet synchronous motor (11) are both installed with a metal collar (16), when the engine (8) and the permanent magnet synchronous motor (11) are in use, the heat on the engine (8) and the permanent magnet synchronous motor (11) is transferred to the collar (16). The collar (16) is connected to the metal plate (18) via a heat conducting rod (17), so the heat on the collar (16) can be transferred to the metal plate (18) via the heat conducting rod (17). The metal plate (18) is installed on the sealing box body (19), so the heat can enter the sealing box body (19), causing the air in the sealing box body (19) to expand due to the heat, thereby causing the fixing plate (2 0) moves upward. When the fixing plate (20) rises, it will squeeze the first spring (21). Under the action of the guide rod (22), the fixing plate (20) will move more smoothly. As the fixing plate (20) rises, air will be pushed into the exhaust pipe (23). A baffle (24) is provided on the inner side of the exhaust pipe (23), and a through hole (29) is opened on the baffle (24). Therefore, gas will flow through the through hole (29), thereby pushing the connecting block (28), so that the connecting block (28) drives the positioning rod (25) to move together. When the positioning rod (25) moves, it drives the limit block (26) to move and squeezes the second spring (27); When the connection block (28) is pushed, it is separated from the exhaust pipe (23) and thus contacts the micro switch (30), turning on the micro switch (30). When the micro switch (30) is turned on, the fan (32) starts to work. The inlet end of the fan (32) is connected to the air inlet pipe (33), and a first shunt pipe (34) is installed on the air inlet pipe (33). The first shunt pipe (34) is provided with an air inlet (35). Therefore, hot gas inside the integrated control box (1) can be adsorbed through the air inlet (35) and then discharged to the outside through the exhaust pipe (36). In this way, the circulation speed of the gas inside the integrated control box (1) can be accelerated, thereby achieving the purpose of heat dissipation inside the integrated control box (1); Step 3: Cool down the integrated control box (1) again A rotating rod (37) is connected to a bearing on the outer wall of the integrated control box (1), and a connecting blade (38) is installed on the outer wall of the rotating rod (37). The connecting blade (38) and the outlet end of the exhaust pipe (36) are located on the same horizontal line. Therefore, when the exhaust pipe (36) discharges gas, the connecting blade (38) is driven to rotate, thereby driving the rotating rod (37) to rotate. A cam (39) is also installed on the outer wall of the rotating rod (37). Therefore, the cam (39) is rotated. When the cam (39) rotates, the rotating rod (37) rotates. When the airbag (40) is squeezed, the gas inside the airbag (40) is transported to the second shunt pipe (42) through the delivery pipe (41). The second shunt pipe (42) is located in the integrated control box (1), so that the inside of the integrated control box (1) can be blown to achieve the purpose of cooling again. The inlet of the airbag (40) and the second shunt pipe (42) are both equipped with a one-way valve. Therefore, when the airbag (40) is reset to inhale, the second shunt pipe (42) will not inhale, thereby ensuring the normal operation of the second heat dissipation work.
