Technical Field

[0001] The present invention relates to the field of motor cooling, and in particular to a motor cooling device for a new energy recreational vehicle. Background Art

[0002] Traditional cooling methods for new energy vehicle motors are mostly air cooling or water cooling. Since the range of new energy RVs depends on limited battery capacity, higher cooling energy consumption will result in a shorter range, so a more efficient heat dissipation cooling system is needed. Moreover, since RVs are mostly used outdoors, they often encounter scenes with a lot of dust and flying insects. In these scenes, the motors are very likely to overheat, resulting in energy waste.

[0003] However, the existing device is not uniform and comprehensive enough when cooling the motor, and in outdoor environments, it is not convenient to efficiently remove impurities such as flying insects and dust that affect the cooling of the motor, thereby reducing the cooling efficiency of the motor.

[0006] In one embodiment, the air guide mechanism includes a fan, which is fixedly connected to the closed frame, and a side of the fan away from the closed frame is fixedly connected to an air guide cover, and a side of the air guide cover away from the fan is fixedly connected to six air guide pipes, and each of the air guide pipes is fixedly connected to an air outlet pipe on the side away from the air guide cover, and a plurality of air outlet ports are opened on one side of the air outlet pipe, and the air outlet pipe is internally connected to the air guide pipe and the air guide cover.

[0008] In one embodiment, a cleaning mechanism is further included, the cleaning mechanism being arranged on the closed frame and being used to clean the filter screen on the front frame, the cleaning mechanism comprising two guide rails, the two guide rails being fixedly connected to both sides of the closed frame respectively, the two guide rails being slidably connected to a sliding cross bar, a scraper being slidably connected between the two sliding cross bars, a plurality of scraping strips being provided on the scraper, round rods being fixedly connected to both sides of the scraper, guide racks being fixedly connected to both sides of the closed frame, parallelogram holes being opened on the guide racks, and the round rods being positioned In the parallelogram hole on the guide frame, and in contact with the inner wall of the guide frame, each of the round rods is rotatably connected to a rotating magnetic ring, each of the guide frames is fixedly connected to an iron plate, the rotating magnetic ring is magnetically attracted to the iron plate, the closed frame is fixedly connected to a support frame, and the support frame is rotatably connected to a driven gear, the driven gear is meshed with the toothed disc, and a curved rod is fixedly connected to one side of the driven gear, one of the sliding cross bars is fixedly connected to a limiting plate on a side close to the driven gear, a straight groove is opened on the limiting plate, and one side of the curved rod is located in the straight groove of the limiting plate.

[0009] In one embodiment, a dust removal mechanism is further included, which is arranged on the guide tube and is used to clean dust on the surface of the motor. The dust removal mechanism includes a connecting bracket, which is fixedly connected between the six guide tubes. One side of the connecting bracket is rotatably connected to a rotating ring, and the rotating ring has two inclined grooves. One side of the rotating ring is fixedly connected to a brush rod rack, wherein two of the movable racks are fixedly connected to a connecting rod, and a movable ring is fixedly connected between the two connecting rods.

The swinging rotating elbow can make the air blow to a larger area, making the cooling effect of the automobile motor better and more uniform.

[0011] 2. When the scraper moves downward, the rotating magnetic ring will magnetically attract the iron plate, so that the scraper bar of the scraper sticks to the filter screen of the front frame and scrapes downward. Then the scraper continues to move downward. Under the guidance of the parallelogram hole on the guide frame, the round rod is squeezed and drives the scraper to move horizontally a distance away from the sliding cross bar, so that the scraper bar on the scraper is out of contact with the filter screen on the front frame, and the rotating magnetic ring is also out of contact with the iron plate.

The moving magnetic ring is also magnetically attracted to the iron plate again, and it moves back and forth. As the car is running at high speed, air continuously passes through the filter on the front frame into the front frame and the closed frame. If the impurities such as the dead flying insects adhering to the filter of the front frame are not completely scraped off, they will be pressed on the filter of the front frame due to the high-speed airflow. The scraping bars on the scraper move back and forth, combined with the guidance of the parallelogram holes on the guide frame, the scraper can scrape the impurities on the filter of the front frame downwards through reciprocating scraping, and finally scrape the impurities off the filter of the front frame, so that the impurities are removed more thoroughly and the cooling efficiency is not easily reduced due to blockage of the air intake.

[0012] 3. The brushing movement of the brush rod holder cooperates with the high-speed airflow continuously ejected from the swinging rotating elbow, which can prevent dust from adhering to the surface of the car motor during driving, and thus not easily affect the heat dissipation efficiency of the car motor. When the car is parked for a long time, some dust and impurities may adhere to the car motor. After the car is started, the brushing action of the brush rod holder can also make these already adhered dust and impurities easier to remove. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] Example 1 A motor cooling device for a new energy RV, such as Figure 1-11As shown, it includes a front frame 1, a filter is provided on one side of the front frame 1, a closed frame 2 is fixedly connected to one side of the front frame 1, two mounting plates 3 are fixedly connected to the closed frame 2, a drive motor 41 is fixedly connected to one side of the front frame 1, a plurality of swing baffles 42 are rotatably connected to the front frame 1, a linkage assembly 43 is connected between the rotating shafts of the plurality of swing baffles 42, an output shaft of the drive motor 41 is connected to the rotating shaft of one of the swing baffles 42, an air guide mechanism is provided on one side of the closed frame 2, the air guide mechanism is used to divert and guide the airflow, and a swing mechanism is provided on the air guide mechanism, the swing mechanism is used to change the flow direction of the airflow.

[0027] The air guide mechanism includes a fan 51, which is fixedly connected to the closed frame 2. The fan 51 is fixedly connected to a guide cover 52 on the side away from the closed frame 2. The guide cover 52 is fixedly connected to six guide pipes 53 on the side away from the fan 51. Each of the guide pipes 53 is fixedly connected to an air outlet pipe 54 on the side away from the guide cover 52. A plurality of air outlets are opened on one side of the air outlet pipe 54. The air outlet pipe 54 is internally connected to the guide pipe 53 and the guide cover 52.

[0028] The swing mechanism includes a gear rod 61, which is rotatably connected to the air guide cover 52. A transmission assembly 62 is connected between the gear rod 61 and the central axis of the fan 51. A limit frame 63 is fixedly connected to the air guide cover 52. A toothed disc 64 is rotatably connected to the limit frame 63. The toothed disc 64 is meshed with the gear rod 61. Six push rods 65 are fixedly connected to the side of the toothed disc 64. Each of the air guide tubes 53 is fixedly connected to a straight plate 66. Each of the straight plates 66 has a sliding It is connected to a movable frame 67, on which several racks are provided, and adjacent racks are staggered. A return spring 68 is connected between the movable frame 67 and the straight plate 66. Each of the movable frames 67 is fixedly connected to a bevel block 69 on one side close to the toothed disc 64. The air outlet of each of the air outlet pipes 54 is rotatably connected to a rotating elbow 610, and each of the rotating elbows 610 is fixedly connected to a swing gear 611, which engages with the rack on the movable frame 67.

[0029] In actual work, the device is first installed on the front of the vehicle through two mounting plates 3, and the side of the front frame 1 with the filter is facing the direction of the RV's movement, and the six air outlet pipes 54 are located around the vehicle motor. Initially, the swing baffle 42 makes the front frame 1 in a closed state. Then, when the RV starts, the drive motor 41 and the fan 51 are started at the same time. The drive motor 41 will drive the swing baffle 42 to rotate 90°, so that the front frame 1 becomes conductive. After the fan 51 is started, the outside air will be sucked in through the front frame 1 and blown into the air deflector 52. When the car starts to move forward, more air will be blown into the air deflector 52 due to the relative movement, and the filter on the front frame 1 will block out insects and other impurities encountered by the RV in the outdoor environment, so that clean air enters the air deflector 52. The air passing through the air deflector 52 will be compressed, and then ejected at high speed from each air outlet of the air outlet pipe 54 through the air deflector 53 and the air outlet pipe 54, and the ejected air will be blown to the car The outer surface of the vehicle motor is cooled. When the fan 51 is started, the fan 51 drives the gear rod 61 to rotate through the transmission assembly 62. The rotation of the gear rod 61 drives the gear plate 64 to rotate together. The rotation of the gear plate 64 drives the six push rods 65 to rotate together. When the push rod 65 rotates, it intermittently squeezes the inclined block 69 to move horizontally in the direction away from the gear plate 64. The horizontal movement of the inclined block 69 drives the moving frame 67 to move horizontally together. The return spring 68 is compressed, and the horizontal movement of the moving frame 67 drives the swing gear 611 and the rotating elbow 610 to swing a certain angle through the rack above. Since the adjacent racks on the moving frame 67 are staggered, the adjacent two swing gears 611 rotate in opposite directions, that is, the adjacent two rotating elbows 610 swing in opposite directions. The air blown out from the outlet of the outlet pipe 54 will be sprayed to the outer surface of the vehicle motor through the rotating elbow 610. The swinging rotating elbow 610 can make the air blown to a larger area, so that the cooling effect of the vehicle motor is better and more uniform.

[0030] Example 2 On the basis of Example 1, Figure 8-9As shown, a cleaning mechanism is also included, which is provided on the closed frame 2 and is used to clean the filter on the front frame 1. The cleaning mechanism includes two guide rails 71, and the two guide rails 71 are respectively fixedly connected to both sides of the closed frame 2. A sliding cross bar 72 is slidably connected to the two guide rails 71, and a scraper 73 is slidably connected between the two sliding cross bars 72. A plurality of scraping strips are provided on the scraper 73, and round rods 74 are fixedly connected on both sides of the scraper 73. Guide frames 75 are fixedly connected on both sides of the closed frame 2, and parallelogram holes are opened on the guide frames 75. The round rods 74 are located on the parallelogram holes on the guide frames 75. The cam 76 is fixedly connected to the guide frame 75, and the rotating magnetic ring 76 is magnetically attracted to the iron plate 77. The closed frame 2 is fixedly connected to a support frame 78, and the support frame 78 is rotatably connected to a driven gear 79. The driven gear 79 is meshed with the toothed disc 64, and a curved rod 710 is fixedly connected to one side of the driven gear 79. One of the sliding cross bars 72 is fixedly connected to a limiting plate 711 on one side close to the driven gear 79. A straight groove is provided on the limiting plate 711, and one side of the curved rod 710 is located in the straight groove of the limiting plate 711.

[0031] The rotation of the gear wheel 64 drives the driven gear 79 to rotate together, and the rotation of the driven gear 79 drives the crankshaft 710 to rotate. The rotation of the crankshaft 710 drives the limit plate 711 and the sliding cross bar 72 to move up and down. The up and down reciprocating movement of the sliding cross bar 72 drives the scraper 73 and the round rod 74 to move up and down together. When the scraper 73 moves downward, the rotating magnetic ring 76 will magnetically attract the iron plate 77, thereby causing the scraping bar of the scraper 73 to scrape downward along the filter of the front frame 1. Then the scraper 73 continues to move downward, and under the guidance of the parallelogram hole on the guide frame 75, the round rod 74 is squeezed and drives the scraper 73 to move horizontally a distance away from the sliding cross bar 72, so that the scraping bar on the scraper 73 is out of contact with the filter on the front frame 1, and the rotating magnetic ring 76 is also attracted to the iron plate 77. When the iron plate 77 is out of contact, the scraper 73 moves upward and moves a distance upward. Then the round rod 74 is guided by the guide frame 75 to move horizontally in the direction close to the sliding cross bar 72, so that the scraping strips on the scraper 73 come into contact with the filter screen on the front frame 1 again, and the rotating magnetic ring 76 is magnetically attracted to the iron plate 77 again, and this reciprocating motion is repeated. As the car is running at high speed, air continuously passes through the filter screen on the front frame 1 and enters the front frame 1 and the closed frame 2. If impurities such as the dead flies adhering to the filter screen of the front frame 1 are not completely scraped off, they will be pressed on the filter screen of the front frame 1 due to the high-speed airflow. The scraping strips on the scraper 73 move back and forth, combined with the guidance of the parallelogram holes on the guide frame 75, the scraper 73 can scrape the impurities on the filter screen of the front frame 1 continuously downward through the reciprocating scraping, and finally the impurities are scraped off the filter screen of the front frame 1, so that the impurities are removed more thoroughly and the cooling efficiency is not easily reduced due to clogging of the air intake.

[0032] Example 3 On the basis of Example 2, Figure 10-11 As shown, it also includes a dust removal mechanism, which is arranged on the guide tube 53 and is used to clean the dust on the surface of the motor. The dust removal mechanism includes a connecting bracket 81, which is fixedly connected between the six guide tubes 53. One side of the connecting bracket 81 is rotatably connected to a rotating ring 82, and the rotating ring 82 has two inclined grooves. One side of the rotating ring 82 is fixedly connected to a brush rod bracket 83, wherein two of the movable frames 67 are fixedly connected to a connecting rod 84, and a movable ring 85 is fixedly connected between the two connecting rods 84. The inner wall of the movable ring 85 is fixedly connected to two protrusions 86, and the two protrusions 86 are respectively located in the two inclined grooves on the rotating ring 82.

[0033] When the brush rod 83 is rotated by the rotating ring 82, the brush rod 83 can be rotated together with the rotating ring 82.
