[0002] In electric vehicles, efficient heat dissipation from the motor directly impacts its performance and lifespan. Because electric vehicle motors typically feature high power density and miniaturization, they generate significant heat during operation.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1-8 The figure shows a spiral duct heat dissipation motor, including a motor housing 1, a support frame 5 is fixedly installed inside the motor housing 1, and a spiral air duct is formed between the support frame 5 and the motor housing 1, and a stator 3 is fixedly installed on the inner wall of the support frame 5. A rotating shaft 2 is rotatably installed inside the motor housing 1, and the rotating shaft 2 is horizontally arranged. A rotor 4 is fixedly installed on the outer surface of the rotating shaft 2. An air outlet is opened on one side of the motor housing 1, and a cylinder 7 is fixedly installed on the end of the motor housing 1 away from the air outlet. The cylinder 7 and the support frame 5 are fixedly connected. An air inlet mechanism is provided inside the cylinder 7, and a partition 8 is fixedly installed on the end of the cylinder 7 away from the support frame 5. An air inlet 9 is opened on the upper part of the partition 8. An opening and closing plate 10 is hinged on the side of the partition 8 close to the support frame 5. The area of ​​the opening and closing plate 10 is larger than the area of ​​the air inlet 9. A through hole 11 is opened at the end of the motor housing 1 away from the air outlet, and a filter element 13 is detachably installed on the inside of the motor housing 1 on the side close to the through hole 11, and a squeezing mechanism is provided on the outside of the filter element 13.

[0022] Specifically, with the cooperation of the stator 3 and the rotor 4, when the motor is running, the rotating shaft 2 can rotate inside the motor housing 1, and the air intake mechanism draws the air outside the motor housing 1 into the interior of the cylinder 7 through the through hole 11. During this process, the wind passes through the filter element 13. The filter element 13 is a sponge in this embodiment and can absorb moisture in the air. The squeezing mechanism can squeeze out the water inside the filter element 13 and keep the filter element 13 dry, thereby ensuring the use effect of the filter element 13 and reducing the moisture in the air entering the motor housing 1. Under the action of the partition 8, the air can be transported to the interior of the spiral air duct through the air inlet 9. At this time, the baffle 12 is in an open state. The air can cool the inside of the motor housing 1 when passing through the spiral air duct, and the air is discharged through the air outlet, thereby taking away the heat inside the motor housing 1.

[0023] The air intake mechanism includes a piston plate 6, which is slidably installed inside the cylinder 7. A moving component is provided on the side of the piston plate 6 close to the rotating shaft 2, and a baffle 12 is provided on the side of the piston plate 6 close to the through hole 11. The baffle 12 is slidably connected to the motor housing 1 through a sliding structure. The area of ​​the baffle 12 is larger than the area of ​​the through hole 11, and the baffle 12 is connected to the piston plate 6 through an adjusting component.

[0024] In the initial state, the piston plate 6 is at one end near the through hole 11 inside the cylinder 7, and the baffle 12 blocks the through hole 11. With the cooperation of the moving assembly, the moving assembly drives the piston plate 6 to move back and forth inside the cylinder 7 along the length direction of the rotating shaft 2. When the piston plate 6 moves away from the through hole 11, the air outside the motor housing 1 can be drawn into the interior of the motor housing 1 through the through hole 11. At the same time, under the action of the adjusting assembly, the adjusting assembly drives the two sets of baffles 12 away from each other, so that the baffle 12 no longer blocks the through hole 11, facilitating the passage of air through the through hole 11. When the piston plate 6 moves toward the through hole 11, the baffle 12 blocks the through hole 11, so that the air inside the motor housing 1 cannot be discharged through the through hole 11, and the piston plate 6 transports the air inside the cylinder 7 to the interior of the spiral air duct through the air inlet 9.

[0025] The moving assembly includes two groups of cross bars 32. The two groups of cross bars 32 are fixedly mounted on the side of the support frame 5 close to the piston plate 6. The outer surfaces of the two groups of cross bars 32 are slidingly sleeved with an adjustment plate 33. The side of the adjustment plate 33 close to the piston plate 6 is rotatably mounted with a push plate 35. The end of the push plate 35 away from the adjustment plate 33 is rotatably connected to the piston plate 6. A power structure is provided on the outside of the adjustment plate 33.

[0026] The power structure includes a turntable 30, which is fixedly mounted on one end of the rotating shaft 2 close to the piston plate 6. A protrusion 31 is fixedly mounted on the edge of the turntable 30 close to the piston plate 6. A movable groove 34 is opened inside the adjustment plate 33, and the movable groove 34 and the protrusion 31 are slidably connected.

[0027] Specifically, the rotating shaft 2 drives the turntable 30 to rotate, and the turntable 30 drives the protrusion 31 to move synchronously when rotating. Since the protrusion 31 is slidably connected to the movable groove 34, the protrusion 31 can drive the adjustment plate 33 to move on the outer surface of the cross bar 32 along the length direction of the cross bar 32, thereby driving the push plate 35 and the end connected to the adjustment plate 33 to move, thereby driving the piston plate 6 to move inside the cylinder 7 through the push plate 35.

[0028] The sliding structure includes a slide groove 14 and a slider 15 . The slide groove 14 is provided on the inner wall of the motor housing 1 near one end of the through hole 11 . The slider 15 is slidably installed inside the slide groove 14 . The slider 15 is fixedly connected to the baffle 12 .

[0029] The adjusting assembly includes a push rod 18 and a mounting seat 19. The mounting seat 19 is connected to one end of the piston plate 6 near the through hole 11 through an elastic structure. One end of the push rod 18 is rotatably connected to the mounting seat 19, and the other end of the push rod 18 is rotatably connected to the baffle 12.

[0030] The elastic structure includes a guide groove 20, which is opened inside the end of the piston plate 6 close to the through hole 11. A slide rod 21 is fixedly installed inside the guide groove 20, and the slide rod 21 is slidably connected to the mounting seat 19. A spring No. 1 movably sleeve is provided on the outer surface of the slide rod 21, and the spring No. 1 22 is fixedly connected to the mounting seat 19. A limiting structure is set between the mounting seat 19 and the piston plate 6.

[0031] The limiting structure includes a groove 25, which is opened inside the end of the mounting seat 19 away from the push rod 18. A No. 2 spring 26 is movably installed inside the groove 25, and a limiting block 23 is fixedly installed on the end of the No. 2 spring 26 away from the groove 25. A limiting hole 24 is opened inside the piston plate 6, and the limiting block 23 slides through the limiting hole 24.

[0032] Specifically, when the piston plate 6 moves away from the through hole 11, the piston plate 6 drives the push rod 18 to rotate under the action of the elastic structure, and the push rod 18 pulls the two sets of baffles 12 away from each other. At this time, the baffle 12 drives the slider 15 to slide inside the slide groove 14. When the slider 15 cannot move inside the slide groove 14, the piston plate 6 continues to move. Under the action of the push rod 18, the mounting seat 19 slides on the outer surface of the slide rod 21, and the No. 1 spring 22 is deformed by the force. When the piston plate 6 stops moving, the limit block 23 moves to the position of the limit hole 24. Under the cooperation of the groove 25 and the No. 2 spring 26 , the limit block 23 passes through the limit hole 24, at this time the mounting seat 19 and the piston plate 6 are fixed together, when the piston plate 6 moves toward the direction close to the through hole 11, the piston plate 6 drives the two groups of baffles 12 to approach each other through the push rod 18. It should be noted that the elastic coefficient of the No. 2 spring 26 is greater than the elastic coefficient of the No. 1 spring 22. When the two groups of baffles 12 stop moving, the piston plate 6 continues to move, thereby pushing the limit block 23 to the inside of the groove 25, and the No. 2 spring 26 is deformed under the force. At this time, the mounting seat 19 and the piston plate 6 are separated, and the No. 1 spring 22 can push the mounting seat 19 to move inside the guide groove 20.

[0033] The extrusion mechanism includes a fixed plate 16, which is fixedly installed inside the motor housing 1 near one end of the through hole 11. There are two groups of filters 13, and the fixed plate 16 is located between the two groups of filters 13. The lower end surface of the fixed plate 16 is inclined. A clamping plate 17 is fixedly installed at one end of the baffle 12 near the filter 13, and the clamping plate 17 is in contact with the filter 13.

[0034] A rod 28 is rotatably mounted below the clamping plate 17 , and a roller 27 is rotatably mounted on one end of the rod 28 away from the clamping plate 17 . The roller 27 contacts and cooperates with the inner wall of the motor housing 1 , and a groove 29 is provided on the lower inner wall of the motor housing 1 .

[0035] Specifically, when the baffle 12 moves, it can drive the splint 17 to move synchronously. When the two sets of splints 17 approach each other, under the action of the fixed plate 16, the filter element 13 can be squeezed to squeeze out the water inside the filter element 13. Since the lower end surface of the fixed plate 16 is inclined, the water can flow along the lower end surface of the fixed plate 16 along the inner wall of the motor housing 1 to the bottom of the inside of the motor housing 1.

[0036] When the splint 17 moves, the roller 27 is driven to move by the rod 28. The roller 27 can move along the inner wall of the motor housing 1, so that the water at the bottom of the motor housing 1 can be smeared to the inner wall of the motor housing 1. Under the action of the groove body 29, the water can be dispersed on the inner wall of the groove body 29, which is conducive to accelerating the evaporation of water and can further cool the interior of the motor housing 1. Moreover, under the action of the partition 8, the water will not contact the stator 3 and the rotor 4, which can reduce the impact of water on the internal parts of the motor and help extend the service life of the motor.

[0037] Working principle: With the cooperation of the stator 3 and the rotor 4, when the motor is running, the rotating shaft 2 can rotate inside the motor housing 1, and the rotating shaft 2 drives the turntable 30 to rotate. When the turntable 30 rotates, it drives the protrusion 31 to move synchronously. Since the protrusion 31 and the movable groove 34 are slidingly connected, the protrusion 31 can drive the adjustment plate 33 to move on the outer surface of the cross bar 32 along the length direction of the cross bar 32, thereby driving the push plate 35 and the end connected to the adjustment plate 33 to move, so that the piston plate 6 can be driven to move inside the cylinder 7 through the push plate 35.

[0038] In the initial state, the piston plate 6 is at one end near the through hole 11 inside the cylinder 7, and the baffle 12 blocks the through hole 11. When the piston plate 6 moves away from the through hole 11, under the action of the elastic structure, the piston plate 6 drives the push rod 18 to rotate, and the push rod 18 pulls the two sets of baffles 12 away from each other, so that the air outside the motor housing 1 can be drawn into the interior of the motor housing 1 through the through hole 11. At this time, the baffle 12 drives the slider 15 to slide inside the slide groove 14. When the slider 15 cannot move inside the slide groove 14, the piston plate 6 continues to move. Under the action of the push rod 18, the mounting seat 19 slides on the outer surface of the slide rod 21, and the No. 1 spring 22 is deformed under the force. When the piston plate 6 stops moving, the limit block 23 moves to the position of the limit hole 24. Under the mutual cooperation of the groove 25 and the No. 2 spring 26 , the limit block 23 passes through the limit hole 24, at this time the mounting seat 19 and the piston plate 6 are fixed together, when the piston plate 6 moves toward the direction close to the through hole 11, the piston plate 6 drives the two sets of baffles 12 to approach each other through the push rod 18, and the baffle 12 blocks the through hole 11, so that the air inside the motor housing 1 cannot be discharged through the through hole 11, and the piston plate 6 delivers the air inside the cylinder 7 to the inside of the spiral air duct through the air inlet 9. It should be noted that the elastic coefficient of the No. 2 spring 26 is greater than the elastic coefficient of the No. 1 spring 22. When the two sets of baffles 12 stop moving, the piston plate 6 continues to move, so that the limit block 23 can be pushed to the inside of the groove 25, and the No. 2 spring 26 is deformed under the force. At this time, the mounting seat 19 and the piston plate 6 are separated, and the No. 1 spring 22 can push the mounting seat 19 to move inside the guide groove 20.

[0039] When the baffle 12 moves, it can drive the splint 17 to move synchronously. When the two sets of splints 17 approach each other, under the action of the fixed plate 16, the filter element 13 can be squeezed to squeeze out the water inside the filter element 13. Since the lower end surface of the fixed plate 16 is inclined, the water can flow along the lower end surface of the fixed plate 16 along the inner wall of the motor housing 1 to the bottom of the inside of the motor housing 1.

[0040] When the splint 17 moves, the roller 27 is driven to move by the rod 28. The roller 27 can move along the inner wall of the motor housing 1, so that the water at the bottom of the motor housing 1 can be smeared to the inner wall of the motor housing 1. Under the action of the groove body 29, the water can be dispersed on the inner wall of the groove body 29, which is conducive to accelerating the evaporation of water and can further cool the interior of the motor housing 1. Moreover, under the action of the partition 8, the water will not come into contact with the stator 3 and the rotor 4.
