[0002] The automobile air conditioning system includes a compressor, a drying bottle, an evaporator, high and low pressure pipes, and an expansion valve. Usually, there are four processes in the air conditioning cycle: compression process, condensation process, expansion process and evaporation process. After these processes, ordinary air becomes low-temperature and low-pressure gas, and the role of the blower is to blow these gases out through the air outlet of the air conditioner. The blower is generally composed of a blower motor, an impeller, a shell and other structures.

[0033] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0034] A car air conditioner blower motor, such as Figure 1 As shown, it includes a motor body 1, a casing 2 and a cooling pipe 6. The output end of the motor body 1 is fixedly connected to the driving shaft 3. The outer surface of the motor body 1 is installed with a casing 4, and a cavity 5 is formed between the casing 4 and the motor body 1. The cooling pipe 6 is located inside the cavity 5 and is wound around the outer surface of the motor body 1. The motor body 1 includes a stator and a rotor, and the rotor is fixedly connected to the driving shaft 3. The cooling pipe 6 is wound around the outer surface of the motor body 1 in an S shape, so that after cold water is passed into the interior of the cooling pipe 6, the motor body 1 can be water-cooled and dissipated.

[0035] like Figure 1 , Figure 2 and Fig. 9As shown, the interior of the housing 2 is fixedly connected to a water tank 9, and a plurality of equidistantly arranged heat dissipating fins 7 are fixedly installed inside the water tank 9, and the end of each heat dissipating fin 7 away from the motor body 1 penetrates the water tank 9 and extends to the outside of the water tank 9, the heat dissipating fin 7 is stepped and a water leakage hole 8 for water supply is opened at its lower end, and the water guide mechanism includes a water pump 46 installed on one side of the water tank 9, the water pumping end of the water pump 46 is fixedly connected to one end of the cooling pipe 6, and the other end of the cooling pipe 6 is fixedly connected to the bottom of the water tank 9, and the drainage end of the water pump 46 is fixedly connected to a drainage pipe 44, and the other end of the drainage pipe 44 is plugged into the interior of the water tank 9, and The drain pipe 44 is located above the multiple heat dissipation fins 7. When the water pump 46 is started, the water pump 46 can suck out the cooling water inside the cooling pipe 6 and discharge it into the water tank 9 through the drain pipe 44. After the cold water flows through the multiple heat dissipation fins 7, it will fall to the bottom of the water tank 9. The heat dissipation fins 7 can conduct the heat in the cooling water to the outside of the water tank 9, thereby accelerating the cooling of the cooling water. The water that falls to the bottom of the water tank 9 will soak the cooling pipe 6 inside the water tank 9, so that the cooled water will flow back again, thereby forming a water cycle. A flow rate valve is installed on the drain pipe 44 to ensure that the water can slowly flow down from the multiple heat dissipation fins 7 in sequence.

[0041] like Figure 5 , Figure 6 and Figure 7As shown, a reciprocating screw 27 is rotatably installed between the first support plate 26 and the outer shell 2, and the reciprocating screw 27 is fixedly connected to the end of the fourth rotating shaft 23 that is close to each other, and a threaded block 28 is threadedly connected to the outer surface of the reciprocating screw 27, and the threaded block 28 is slidably connected to the inner wall of the outer shell 2, and two fifth rotating shafts 29 are rotatably installed inside the threaded block 28, and a second support plate 32 is rotatably installed on the outer surface of the fifth rotating shaft 29, and the second support plate 32 is slidably connected to the inner wall of the outer shell 2, and a side of the second support plate 32 away from the fifth rotating shaft 29 is fixedly connected to one of the fan shells 41, and the rotation of the fourth rotating shaft 23 can drive the reciprocating screw 27 to rotate, and the rotation of the reciprocating screw 27 can drive the threaded block 28 to reciprocate along the reciprocating screw 27, and the movement of the threaded block 28 can drive the fifth rotating shaft 29, the second support plate 32, the fan shell 41, the second fan blade 45 and the arc-shaped suction cylinder 35 to move accordingly.

[0042] like Figure 6 As shown, the outer surfaces of the two fifth rotating shafts 29 are fixedly connected with the third gear 30, and the interior of the housing 2 is fixedly connected with two toothed plates 31, and the toothed plates 31 are meshed with the third gear 30. The reciprocating movement of the threaded block 28 can drive the third gear 30 to reciprocate along the toothed plates 31. The third gear 30 will rotate itself during the reciprocating movement along the toothed plates 31, and the rotation of the third gear 30 can drive the fifth rotating shaft 29 to rotate accordingly.

[0043] like Figure 5 and Figure 6As shown, the outer surfaces of the two fifth rotating shafts 29 are fixedly connected with the fifth synchronous wheel 33 and the sixth synchronous wheel 34, wherein the outer surfaces of the two sixth rotating shafts 36 are installed with the first one-way bearings 37, the seventh synchronous wheel 38 is installed on the first one-way bearings 37, and the seventh synchronous wheel 38 is connected to the fifth synchronous wheel 33 through the third synchronous belt transmission, and the outer surfaces of the other two sixth rotating shafts 36 are installed with the second one-way bearings 39, the eighth synchronous wheel 40 is installed on the second one-way bearings 39, and the eighth synchronous wheel 40 is connected to the sixth synchronous wheel 34 through the fourth synchronous belt transmission, the first one-way bearings 37 and the second one-way bearings 39 rotate in opposite directions, when the threaded block 28 moves horizontally along the reciprocating screw 27 in the direction away from the second gear 25, it can drive the third gear 30, the fifth rotating shaft 29, the fifth synchronous wheel 33 and the sixth synchronous wheel 34 to rotate forwardly, The positive rotation of the fifth synchronous wheel 33 can drive the seventh synchronous wheel 38, the sixth rotating shaft 36 below and the second fan blade 45 to rotate positively. The positive rotation of the sixth synchronous wheel 34 will only drive the eighth synchronous wheel 40 to rotate idly, and the sixth rotating shaft 36 and the second fan blade 45 above will not rotate. Similarly, when the threaded block 28 moves horizontally along the reciprocating screw rod 27 toward the direction of the second gear 25, it can drive the third gear 30, the fifth rotating shaft 29, the fifth synchronous wheel 33 and the sixth synchronous wheel 34 to rotate in the opposite direction. The reverse rotation of the fifth synchronous wheel 33 will only drive the seventh synchronous wheel 38 to rotate idly, and the sixth rotating shaft 36 and the second fan blade 45 above will not rotate. The reverse rotation of the sixth synchronous wheel 34 can drive the eighth synchronous wheel 40, the sixth rotating shaft 36 and the second fan blade 45 to rotate positively, so that during the reciprocating movement of the threaded block 28, a second fan blade 45 can always be kept in positive rotation.

[0044] like Figure 4 and Figure 8 As shown, an air collecting shell 42 is provided inside the outer shell 2, and the air collecting shell 42 is fixedly mounted on the side of the two fan shells 41 away from the motor body 1.

The positive rotation of the second fan blade 45 can suck the hot air generated during the working process of the motor body 1 into the interior of the air collecting shell 42, and then discharge it to the designated position through the exhaust hose 43.

[0045] Working principle: When the motor body 1 is working, the water pump 46 is started. The water pump 46 can suck out the cooling water inside the cooling pipe 6 and discharge it into the water tank 9 through the drain pipe 44. After the cold water flows through multiple heat dissipation fins 7, it will fall to the bottom of the water tank 9. The heat dissipation fins 7 can conduct the heat in the cooling water to the outside of the water tank 9, thereby accelerating the cooling of the cooling water. The water falling to the bottom of the water tank 9 will soak the cooling pipe 6 inside the water tank 9, so that the cooled water will flow back again, thereby forming a water cycle. At the same time, the operation of the motor body 1 will drive the drive shaft 3 to rotate. The rotation of the drive shaft 3 can drive the first synchronous wheel 12, the second synchronous wheel 13, the first rotating shaft 11 and the first fan blade 16 to rotate. The rotation of the first fan blade 16 can absorb the heat on the heat dissipation fin 7 and discharge it from the inside of the shell 2 through the exhaust hole 17, and then the hot air will be discharged to the designated position through the exhaust hard pipe 19, thereby realizing rapid cooling of the cooling water.

The rotation of the third rotating shaft 20 can drive the first gear 24, the second gear 25 and the fourth rotating shaft 23 to rotate synchronously. The rotation of the fourth rotating shaft 23 can drive the reciprocating screw rod 27 to rotate. The rotation of the reciprocating screw rod 27 can drive the threaded block 28 to reciprocate along the reciprocating screw rod 27. The movement of the threaded block 28 can drive the fifth rotating shaft 29, the second supporting plate 32, the fan shell 41, the second fan blade 45 and the arc-shaped suction tube 35 to move accordingly. When the threaded block 28 moves horizontally along the reciprocating screw rod 27 in the direction away from the second gear 25, it can drive the third gear 30, the fifth rotating shaft 29, the fifth synchronous wheel 33 and the sixth synchronous wheel 34 to rotate forwardly. The forward rotation of the fifth synchronous wheel 33 can drive the seventh synchronous wheel 38, the sixth rotating shaft 36 below and the second fan blade 45 to rotate forwardly. The forward rotation of the sixth synchronous wheel 34 will only The eighth synchronous wheel 40 is driven to rotate idly, and the sixth rotating shaft 36 and the second fan blade 45 above will not rotate. Similarly, when the threaded block 28 moves horizontally along the reciprocating screw 27 toward the direction of the second gear 25, the third gear 30, the fifth rotating shaft 29, the fifth synchronous wheel 33 and the sixth synchronous wheel 34 can be driven to rotate in the opposite direction. The reverse rotation of the fifth synchronous wheel 33 will only drive the seventh synchronous wheel 38 to rotate idly, and the sixth rotating shaft 36 and the second fan blade 45 above will not rotate. The reverse rotation of the sixth synchronous wheel 34 can drive the eighth synchronous wheel 40, the sixth rotating shaft 36 and the second fan blade 45 to rotate forwardly, so that during the reciprocating movement of the threaded block 28, the second fan blade 45 can always be kept rotating forwardly. The forward rotation of the second fan blade 45 can suck the hot air generated during the working process of the motor body 1 into the interior of the wind collecting shell 42, and then discharge it to the designated position through the exhaust hose 43, thereby realizing comprehensive heat dissipation of the motor body 1.
