Description

Technical Field

[0001] This invention relates to the field of new energy vehicle battery management technology, and in particular to a power management system for new energy vehicles. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as a power source and integrate advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include four main types: hybrid electric vehicles, pure electric vehicles, fuel cell electric vehicles, and other new energy vehicles.

[0003] A search revealed a patent with application number 201810952438.8: a power supply dust cleaning device for new energy vehicles. This device uses the rotation of a brush, combined with the airflow generated by a fan blade, to clean dust from the vehicle's power supply unit. However, it also has some shortcomings.

[0004] The process of cleaning dust from a car power supply only cleans the end where dust has already accumulated. Dust entering through the ventilation system will still fall onto the power supply, potentially causing poor contact. Furthermore, brushing the power supply leaves a lot of dust adhering to the brush, which is not cleaned in time and poses a threat of secondary pollution. In addition, the car power supply may generate abnormally high temperatures during prolonged use, requiring cooling. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art and to propose a power management system for new energy vehicles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A power management system for new energy vehicles includes a housing and a new energy battery. The new energy battery is installed inside the housing. A rectangular tube is fixedly connected through the inner wall of the housing. A box is fixedly connected through the side wall of the rectangular tube. A rotating shaft is rotatably connected to the inner wall of the box. Multiple straight plates are evenly fixedly connected to the side wall of the rotating shaft. An electron transmitter is fixedly connected to the side wall of each straight plate away from the rotating shaft. A through hole is opened in the inner wall of the straight plate. A positive grid plate is fixedly connected to the inner wall of the through hole. An insulating layer is provided on the positive grid plate. A film is electroplated on the insulating layer. A thermoelectric generator is fixedly connected to the end of the straight plate away from the rotating shaft. An electromagnet is embedded in the end of the straight plate away from the rotating shaft. Each electromagnet is electrically connected to a thermoelectric generator clockwise adjacent to it. A heat-conducting seat is fixedly connected to the inner wall of the box. A magnet is fixedly connected to the side wall of the heat-conducting seat. Heat-conducting plates are symmetrically fixedly connected to the inner wall of the box. The heat-conducting plates are connected to the heat-conducting seat through heat-conducting wires. A heat sink is fixedly connected to the inner wall of the box.

[0008] Furthermore, the heat-conducting sheet is respectively attached to the side wall opposite to the new energy battery, a memory spring is fixedly connected to the side wall of the heat-conducting sheet, a push rod is fixedly connected to the end of the memory spring away from the heat-conducting sheet, and a dust removal box is fixedly connected to the inner wall of the box.

[0009] Furthermore, a sliding plate is slidably connected inside the dust collector box, and one end of the push rod passes through the inner wall of the dust collector box and is fixedly connected to the side wall of the sliding plate. An air inlet pipe and an air outlet pipe are symmetrically connected through the inner wall of the dust collector box, and a first connecting pipe and a second connecting pipe are fixedly connected through the inner wall of the end of the dust collector box away from the air inlet pipe.

[0010] Furthermore, a rectangular groove is formed on the inner wall of the box, and a telescopic airbag is fixedly connected to the inner wall of the rectangular groove. A magnetic scraper is fixedly connected to one end of the telescopic airbag. A sliding cavity is symmetrically formed on the inner wall of the rectangular groove. One of the sliding cavities is filled with coolant. A magnetic block is slidably connected to the sliding cavity. A plurality of dust suction holes are formed on the inner wall of the rectangular groove.

[0011] Furthermore, the air inlet pipe and the dust suction hole are fixedly connected, the air outlet pipe is fixedly connected to the external environmental dust removal bag, the first connecting pipe is fixedly connected to the telescopic airbag, and a pressure relief pipe is fixedly connected through the inner wall of the telescopic airbag, and a control valve is provided inside the pressure relief pipe.

[0012] Furthermore, a serpentine tube is fixedly connected to the inner wall of the box, one end of the serpentine tube is fixedly connected to the inner wall of one of the sliding cavities, and the other end of the serpentine tube is fixedly connected to the inner wall of another sliding cavity.

[0013] Furthermore, a cooling element is fixedly connected inside the sliding cavity, and the cooling element and the thermoelectric generator are electrically connected. An elastic rod is fixedly connected to the inner wall of the box, and a ground plate is fixedly connected to one end of the elastic rod. The ground plate is connected to the ground through a wire.

[0014] Furthermore, both the air inlet pipe and the air outlet pipe are equipped with one-way valves, and both the first connecting pipe and the second connecting pipe are equipped with one-way valves.

[0015] The present invention has the following advantages:

[0016] 1. Utilizing the heat dissipated during the operation of the new energy battery, through structures such as heat-conducting plates, heat-conducting bases, and thermoelectric generators, multiple straight plates rotate counterclockwise around the pivot, causing the positive grid plate to partially block the gas entering the box, slowing down the airflow speed, and allowing negatively charged dust in the air to come into full contact with the positive grid plate, where the negatively charged dust is adsorbed onto the surface of the positive grid plate.

[0017] 2. When each positive grid plate rotates into the box, it will come into contact with the grounding plate and squeeze the elastic rod to deform it, thereby conducting the negative charge on the positive grid plate into the ground. The negatively charged dust gradually loses its negative charge and falls into the rectangular groove under the action of gravity.

[0018] 3. When the heat emitted by the new energy battery causes the temperature of the memory spring to rise, the memory spring contracts and drives the slide plate to slide in the dust removal box through the push rod. The dust around the suction hole is sucked into the left side of the dust removal box through the air inlet pipe, and the gas squeezed in the right side of the dust removal box is put into the telescopic airbag. Then the telescopic airbag is inflated and stretches in a straight line, pushing the magnetic scraper in the rectangular groove to push the dust into the vicinity of the suction hole and be removed.

[0019] 4. As the magnetic scraper slides within the rectangular groove, it pushes the dust in the groove into the suction hole, improving the efficiency of dust collection. Furthermore, the magnetic scraper drives two magnetic blocks to move synchronously, squeezing the coolant cooled by the cooling plate into the serpentine tube to cool and dissipate heat from the new energy battery.

[0025] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Reference Figure 1-4 A power management system for new energy vehicles includes a housing 1 and a new energy battery 14. The new energy battery 14 is installed inside the housing 1. A rectangular tube 2 is fixedly connected through the inner wall of the housing 1. A box 13 is fixedly connected through the side wall of the rectangular tube 2. A rotating shaft 3 is rotatably connected to the inner wall of the box 13. Multiple straight plates 4 are evenly distributed and fixedly connected to the side wall of the rotating shaft 3. Through holes 5 are opened in the inner wall of the straight plates 4. A positive grid plate 6 is fixedly connected to the inner wall of the through holes 5. An insulating layer is provided on the positive grid plate 6. A coating is electroplated on the positive grid plate 6. A thermoelectric generator 9 is fixedly connected to the end of the straight plate 4 away from the rotating shaft 3. An electromagnet 8 is provided, and each electromagnet 8 is electrically connected to a clockwise adjacent thermoelectric generator 9. A heat-conducting seat 10 is fixedly connected to the inner wall of the box 13, and a magnet 11 is fixedly connected to the side wall of the heat-conducting seat 10. Heat-conducting plates 15 are symmetrically fixedly connected to the inner wall of the box 1, and the heat-conducting plates 15 are connected to the heat-conducting seat 10 through heat-conducting wires 16. A heat sink 12 is fixedly connected to the inner wall of the box 13. An electron emitter 7 is fixedly connected to the side wall of the straight plate 4 away from the rotating shaft 3. The heat sink 12 is located below the heat-conducting seat 10. The straight plate 4 is made of non-ferromagnetic material and will not interfere with the interaction between the magnet 11 and the electromagnet 8.

[0027] The heat-conducting sheet 15 is attached to the side wall opposite to the new energy battery 14. A memory spring 20 is fixedly connected to the side wall of the heat-conducting sheet 15. A push rod 19 is fixedly connected to the end of the memory spring 20 away from the heat-conducting sheet 15. A dust removal box 17 is fixedly connected to the inner wall of the box 1. The memory spring 20 is a CuZnAl memory alloy spring. When the heat emitted by the new energy battery 14 causes the temperature of the memory spring 20 to rise, the memory spring 20 changes from an extended state to a contracted state.

[0028] The dust collector 17 is sealed and slidably connected to a sliding plate 18. One end of the push rod 19 passes through the inner wall of the dust collector 17 and is fixedly connected to the side wall of the sliding plate 18. The inner wall of the dust collector 17 is symmetrically connected to an air inlet pipe 28 and an air outlet pipe 29. The inner wall of the end of the dust collector 17 away from the air inlet pipe 28 is connected to a first connecting pipe 30 and a second connecting pipe. After the memory spring 20 contracts, it drives the sliding plate 18 to slide in a sealed manner inside the dust collector 17 through the push rod 19.

[0029] The inner wall of the box 13 has a rectangular groove 27. A telescopic airbag 25 is fixedly connected to the inner wall of the rectangular groove 27. A magnetic scraper 26 is fixedly connected to one end of the telescopic airbag 25. A sliding cavity 32 is symmetrically opened on the inner wall of the rectangular groove 27. One of the sliding cavities 32 is filled with coolant. A magnetic block 33 is slidably connected to the sliding cavity 32. A plurality of dust suction holes 23 are opened on the inner wall of the rectangular groove 27. When the telescopic airbag 25 is extended, it drives the magnetic scraper 26 to slide a certain distance in the rectangular groove 27.

[0030] The air inlet pipe 28 and the dust suction hole 23 are fixedly connected, the air outlet pipe 29 is fixedly connected to the external environmental dust removal bag, the first connecting pipe 30 is fixedly connected to the telescopic airbag 25, and a pressure relief pipe is fixedly connected through the inner wall of the telescopic airbag 25. A control valve is installed in the pressure relief pipe. The air inlet pipe 28 removes the dust in the rectangular groove 27 through the dust suction hole 23.

[0031] A serpentine tube 31 is fixedly connected to the inner wall of the housing 1. One end of the serpentine tube 31 is fixedly connected to the upper inner wall of one of the sliding cavities 32, and the other end of the serpentine tube 31 is fixedly connected to the lower inner wall of another sliding cavity 32. The serpentine tube 31 and the new energy battery 14 are fitted together.

[0032] A cooling plate is fixedly connected inside the sliding cavity 32. The cooling plate and the thermoelectric generator 9 are electrically connected. The thermoelectric generator 9 supplies power to the cooling plate, which cools the coolant. An elastic flexible rod 21 is fixedly connected to the inner wall of the box 13. One end of the elastic flexible rod 21 is fixedly connected to a ground plate 22. The ground plate 22 is connected to the ground through a wire. The cooling plate cools the coolant inside the sliding cavity 32.

[0033] Both the inlet pipe 28 and the outlet pipe 29 are equipped with one-way valves. The first connecting pipe 30 and the second connecting pipe are also equipped with one-way valves. The one-way valve in the inlet pipe 28 only allows dust and gas in the suction hole 23 to be drawn into the left side of the dust collector 17, while the one-way valve in the outlet pipe 29 only allows dust and gas in the dust collector 17 to be squeezed into the environmentally friendly dust collector bag. The one-way valve in the first connecting pipe 30 only allows gas in the right side of the dust collector 17 to be squeezed into the telescopic air bag 25. The one-way valve in the second connecting pipe only allows gas in the box 1 to be drawn into the right side of the dust collector 17.

[0034] In this invention, the rectangular tube 2 is connected to the outside for ventilation and heat dissipation. The new energy battery 14 is installed inside the housing 1. When the new energy battery 14 generates high temperature during use, the heat dissipated causes the temperature of the heat-conducting plate 15 to rise, which in turn causes the temperature of the heat-conducting base 10 to rise through the heat-conducting wire 16. After the temperature of the heat-conducting base 10 rises, the temperature of the thermoelectric generator 9 at one end of a straight plate 4 near it rises. By collecting heat, the thermoelectric generator generates electricity, which causes the adjacent electromagnet 8 to be energized clockwise and generate magnetism. The electromagnet 8 and the magnet 11 have opposite polarities and attract each other magnetically. This causes the energized electromagnet 8 to drive the corresponding straight plate 4 to rotate a certain angle toward the heat-conducting base 10. The corresponding thermoelectric generator 9 moves to the heat sink 12 for heat dissipation, and the corresponding electromagnet 8 is de-energized. The above process is then repeated continuously, causing multiple straight plates 4 to rotate counterclockwise around the pivot 3.

[0035] When the straight plate 4 moves the corresponding electron emitter 7 into the rectangular tube 2, the electron emitter 7 is turned on. The negative electrons emitted from the electron emitter 7 cause the dust contained in the gas entering from the rectangular tube 2 to carry a negative charge.

[0036] Then, the negatively charged dust comes into contact with the positive grid plate 6. The inside of the positive grid plate 6 is positively charged, and the outer coating of the positive grid plate 6 is a metal coating, which is also positively charged. This allows the negatively charged dust to be adsorbed. Furthermore, the positive grid plate 6 rotates counterclockwise with the corresponding straight plate 4, which in turn compresses the gas and dust entering from inside the rectangular tube 2, allowing the negatively charged dust to fully contact and be adsorbed by the positive grid plate 6, thus improving the dust removal effect on the gas.

[0037] When the positive grid plate 6 rotates into the box 13, it will contact the grounding plate 22 and compress the elastic rod 21 to cause deformation, thereby conducting the negative charge on the positive grid plate 6 into the ground. The negatively charged dust gradually loses its negative charge and falls into the rectangular groove 27 under the action of gravity. After the elastic rod 21 bends and deforms to a certain extent, the grounding plate 22 and the corresponding positive grid plate 6 will disengage, and the elastic rod 21 will return to its initial state, causing the grounding plate 22 to contact the other adjacent positive grid plate 6.

[0038] Meanwhile, when the heat emitted by the new energy battery 14 causes the temperature of the memory spring 20 to rise, the memory spring 20 changes from an extended state to a contracted state. After the memory spring 20 contracts, it drives the slide plate 18 to slide in the dust collection box 17 through the push rod 19. After the slide plate 18 slides to the right in the dust collection box 17 for a certain distance, the dust around the suction hole 23 is sucked into the left side of the dust collection box 17 through the air inlet pipe 28, and the gas that squeezes the right side of the dust collection box 17 is put into the telescopic airbag 25. Then the telescopic airbag 25 is inflated and stretches linearly, pushing the magnetic scraper 26 to slide in the rectangular groove 27.

[0039] As the magnetic scraper 26 slides within the rectangular groove 27, it pushes the dust within the groove 27 into the suction hole 23, improving suction efficiency. Furthermore, the magnetic scraper 26 and the two magnetic blocks 33, with opposite polarities, exert a magnetic attraction on each other, causing the two magnetic blocks 33 to move synchronously. One of the magnetic blocks 33 slides upward in a sealed manner within its corresponding sliding cavity 32, thereby squeezing the coolant cooled by the cooling plate into the serpentine tube 31 to cool and dissipate heat from the new energy battery 14. Simultaneously, as the other magnetic block 33 slides upward in a sealed manner, it draws in the coolant originally in the serpentine tube 31, thus maintaining a good cooling effect for the coolant in the serpentine tube 31.

[0040] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
