[0039] Embodiment 2

[0040] Please refer to Figures 1 to 16 , on the basis of Embodiment 1, in order to ensure the heat dissipation effect on both sides of the motor assembly 3, this embodiment proposes that the inner surfaces of the motor upper cover 12 and the motor lower cover 13 are respectively provided with installation grooves adapted to the integrated stator frame 31. The integrated stator frame 31 is snap-fitted and installed between the motor upper cover 12 and the motor lower cover 13. The middle part of the integrated stator frame 31 is a hollow structure. A hollow heat dissipation ring pipe 311 is sleeved and installed inside the integrated stator frame 31. Plastic sealing caps 312 are respectively snap-fitted and installed at both ends of the integrated stator frame 31. Both ends of the hollow heat dissipation ring pipe 311 respectively penetrate the side walls of the plastic sealing caps 312 and are snap-fitted with the outer surface of the plastic sealing caps 312. A driver chip 33 is fixedly installed on the outer surface of a group of plastic sealing caps 312. The input end of the driver chip 33 is electrically connected to the output end of the controller 21, and the output end of the driver chip 33 is electrically connected to the wire end of the double-strand copper winding group 35. The side walls of the two bearing caps 32 are fixedly connected to the side walls of the motor upper cover 12 and the motor lower cover 13 respectively through bolts. Heat dissipation grooves 321 are provided on the side walls of the two bearing caps 32. Bearings 322 adapted to the rotating shaft 37 are fixedly installed in the middle of the two bearing caps 32. The outer surfaces on both sides of the rotating shaft 37 are respectively rotatably connected to the inner surfaces of the bearings 322. A washer 323 is provided inside the bearing cap 32;

[0041] In this embodiment, the upper motor cover 12 and the lower motor cover 13 are internally provided with installation grooves adapted to the integrated stator frame 31 to cooperate with each other to install and fix the integrated stator frame 31, making the assembly of the air-conditioning motor unit more convenient. The integrated stator frame 31 is internally provided with fixing grooves evenly arranged in cooperation with the stator core 34, and empty grooves are arranged inside the fixing grooves, so that the heat generated by the stator core 34 and the double-strand copper winding group 35 can be evenly dissipated. The plastic sealing cover 312 seals both ends of the integrated stator frame 31, so that the integrated stator frame 31, the stator core 34, and the double-strand copper winding group 35 form a stator assembly, with a more stable structure. At the same time, a groove is provided in cooperation with the hollow heat dissipation ring pipe 311, and the hollow heat dissipation ring pipe 311 is inserted into the empty groove of the integrated stator frame 31 to form a left and right through heat dissipation channel to export the heat dissipated inside the integrated stator frame 31. The bearing cover 32 seals both ends of the integrated stator frame 31, and the bearing cover 32 is provided with heat dissipation grooves 321 that cooperate with the heat dissipation ports 121 to facilitate the heat dissipation of the hollow heat dissipation ring pipe 311 and improve the heat dissipation effect inside the integrated stator frame 31. The driver chip 33 receives the control of the controller 21 to change the current in the double-strand copper winding group 35, thereby generating a magnetic field to drive the plastic magnetic rotor 36 to drive the rotating shaft 37 to rotate. The bearing 322 plays a role in installing the rotating shaft 37. The washer 323 fills the gap inside the bearing cover 32 to make the rotation of the rotating shaft 37 more stable. The rotation of the rotating shaft 37 drives the fan blade 42 to rotate, which is used as a wind power component of the automotive air conditioner, further solving the problem of high energy consumption and fast power consumption of the existing motor. The battery life of the motor can be extended by increasing the resistance to enhance heat dissipation and reducing the current, making it more energy-efficient.

[0042] Embodiment Three

[0043] Please refer to Figures 12 to 13 , on the basis of Embodiment Two, in order to ensure that the washer 323 fills the gap of the bearing cover 32 to increase stability without blocking the heat dissipation effect of the heat dissipation grooves 321, a hexagonal grid plate is added inside the washer 323 in this embodiment. The hexagonal grid plates are engaged with each other. An arc-shaped stabilizing piece is arranged inside the hexagonal grid plate. A spring sleeve is fixedly installed between the arc-shaped stabilizing piece and the hexagonal grid plate, and two sets of nested elastic balls are arranged inside the spring sleeve;

[0044] In this embodiment, the hexagonal grid plates are engaged with each other inside the washer 323, which not only increases stability, but also the hollow structure does not block the heat dissipation effect of the hollow heat dissipation ring tube 311. The arc-shaped stabilizing piece is on the outside of the bearing 322 and plays a role in damping the bearing cover 32 when the rotating shaft 37 rotates. The elastic ball keeps the spring in a taut state between the hexagonal grid plate and the arc-shaped stabilizing piece, plays a role in buffering vibrations, eliminates the vibrations of the bearing cover 32 and reduces noise. Furthermore, it solves the problem that the existing motor has high energy consumption and fast power consumption. The battery life of the motor can be extended by increasing the resistance to enhance heat dissipation and reducing the current, which is more energy-efficient.

[0045] Embodiment Four

[0046] Please refer to Figures 14 to 15 , on the basis of Embodiment Three, in order to increase the protection of the driver chip 33 between the driver chip 33 and the plastic sealing cover 312, a protective cover is added outside the hollow heat dissipation ring tube 311 where the driver chip 33 is installed in this embodiment. The side wall of the protective cover is provided with fan-shaped heat dissipation slots for heat dissipation, and the upper side wall of the protective cover is also provided with a circuit wiring slot. At the same time, cylindrical cross-shaped clamping posts are added on the outer side wall of the hollow heat dissipation ring tube 311, and circular cross-shaped clamping grooves for cooperating with the cylindrical cross-shaped clamping posts are provided on the inner side wall of the protective cover;

[0047] In this embodiment, the protective cover can be installed outside the hollow heat dissipation ring tube 311 by engaging the circular cross-shaped clamping groove of the protective cover with the cylindrical cross-shaped clamping post, which plays a role in protecting the driver chip 33 welded on the outer surface of the hollow heat dissipation ring tube 311, avoiding the loosening of the welding wire due to the buffering effect of the driver chip 33 during the use of the motor. At the same time, the fan-shaped heat dissipation slots on the side wall of the protective cover facilitate the heat dissipation of the driver chip 33. Furthermore, it solves the problem that the existing motor has high energy consumption and fast power consumption. The battery life of the motor can be extended by increasing the resistance to enhance heat dissipation and reducing the current, which is more energy-efficient.

[0048] Embodiment Five

[0049] Please refer to Figures 1 to 16On the basis of the fourth embodiment, in order to realize the generation of wind force in the automobile air-conditioning duct, the present embodiment proposes that the hood cover 11 and the side walls of the motor integrated duct 1 are respectively provided with arc-shaped mounting grooves adapted to the hood 4, and the inner walls on both sides of the hood 4 are respectively fixedly installed with an air inlet hood net 41 by bolts, and the interior of the hood 4 is provided with fan blades 42, and two groups of fan blades 42 are respectively fixedly installed on the outer surfaces of both ends of the rotating shaft 37, and the outer walls on both sides of the air inlet hood net 41 are respectively clamped and installed with dust boxes 411, and the outer walls of the dust boxes 411 are inclined serrated, and a central rotating ring 412 is rotatably installed in the middle of the air inlet hood net 41, and the inner wall of the central rotating ring 412 is provided with a clamping groove adapted to the rotating shaft 37, and dust cleaning brushes 413 are respectively fixedly installed on the outer surfaces on both sides of the central rotating ring 412, and the brush side of the dust cleaning brush 413 is in contact with the side surface of the air inlet hood net 41;

[0050] The fan 42 is then driven by the shaft 37 to generate wind and the air inlet hood net 41 is then filtered to prevent dust from entering the fan 42. When the dust box 411 is engaged with the shaft 37, the shaft 37 can drive the dust box 411 to rotate, so that the dust brush 413 can clean the dust net of the air inlet hood net 41. At the same time, the dust box 411 is obliquely engaged and installed on the side wall of the air inlet hood net 41. When the dust brush 413 rotates and passes by, the inclined serrations on its outer wall will comb the dust brush 413 so that dust is collected by the dust box 411, which is convenient for later disassembly of the dust box 411 for cleaning, thereby ensuring the rotation effect of the fan blades 42 and the ventilation effect of the air inlet hood net 41, further solving the problem of high energy consumption and fast power consumption of the existing motor, and can extend the motor's battery life by increasing resistance to enhance heat dissipation and reduce current, which is more energy-efficient.

[0051] Embodiment 6

[0052] See also Figures 1 to 16 Based on the fifth embodiment, this embodiment proposes a method for using a vehicle air conditioner energy-saving motor assembly, comprising the following steps:

[0053] Step 1: The battery 2 supplies power to the whole motor, and the driver chip 33 receives control from the controller 21 to change the current in the double-strand copper winding group 35, thereby generating a magnetic field to make the plastic magnetic rotor 36 drive the shaft 37 to rotate, and the shaft 37 drives the fan blades 42 to generate wind force;

[0054] Step 2: The hollow heat dissipation ring tube 311 is inserted into the empty slot of the integrated stator frame 31 to form a heat dissipation channel that runs through the left rear to guide the heat dissipated from the inside of the integrated stator frame 31. The bearing cover 32 is provided with a heat dissipation groove 321 that cooperates with the heat dissipation port 121 to facilitate the heat dissipation of the hollow heat dissipation ring tube 311.

[0055] Step 3: The upper motor cover 12, the lower motor cover 13, and the air duct cover 11 are fixedly installed with the integrated motor air duct 1 through bolts, which is convenient for disassembly, integrating the motor housing with the automotive air-conditioning air duct. The temperature sensor 22 detects the temperature at the front end of the heat dissipation port 121. After exceeding the highest threshold, the controller 21 controls the telescopic rod 23 to descend through the telescopic rod driver 231, causing the arc-shaped baffle 15 to descend. Under the influence of the descent of the arc-shaped baffle 15 and the limiting cooperation of the limiting rod 17, the air deflector 16 rotates, changing from the downward diversion state to the lateral diversion state, allowing the air flow to enter through the upper part of the arc-shaped baffle 15 and increasing the heat dissipation effect by flowing upward through the rapid heat dissipation groove 131.
