When encountering an uneven road section, the vehicle body will vibrate, causing the shell to move downward, and the shell drives multiple fixed blocks to move downward. The multiple fixed blocks drive multiple rotating blocks to move downward through positioning pins, and the multiple rotating blocks drive multiple connecting rods to move downward. Because the multiple slip rings on the multiple connecting rods are movably mounted with the two fixed rods on the multiple fixed columns, the multiple connecting rods will push the multiple slip rings to move on the two fixed rods, and the springs in the middle of the multiple slip rings will release elastic potential energy to reduce the moving distance of the multiple slip rings on the two fixed rods, thereby reducing the downward moving distance of the multiple connecting rods and the multiple rotating blocks, and also reducing the downward moving distance of the multiple fixed blocks and the shell.

When the incomplete gear does not mesh with the tooth plate, spring two releases the elastic potential energy, pulling a cleaning plate to move in the opposite direction. One cleaning plate drives multiple cleaning plates to move in the opposite direction through the tooth plate and the limit plate, thereby realizing the reciprocating motion of the cleaning plate. When the cleaning plate reciprocates, the air vents can be cleaned, so that the air vents can be cleaned while dissipating heat, thereby avoiding the increase of the internal temperature of the power control device and ensuring the stable operation of the power control device.

[0024] like Figure 1-4As shown, two rotating shafts 10 are fixedly installed on the top inner surface of the shell 1, and a plurality of fan blades 11 are fixedly connected to the side of the two rotating shafts 10 close to the bottom, and a toothed wheel 12 is fixedly installed on the side of the two rotating shafts 10 close to the top, and the outer surfaces of the two toothed wheels 12 are meshingly connected with a toothed wheel 2 13, and the inner surfaces of the two toothed wheels 2 13 are fixedly installed with a rotating shaft 2 14, and an incomplete gear 18 is fixedly installed on the outer surface of one of the rotating shafts 2 14, and a tooth plate 19 is meshingly connected to the outer surface of the incomplete gear 18, and a plurality of cleaning plates 20 are fixedly connected to the side of the tooth plate 19 away from the incomplete gear 18, so that the air vents 16 can be cleaned while dissipating heat, thereby avoiding the increase of the internal temperature of the power control device and ensuring the stable operation of the power control device.
[0025] like Figure 1-4 As shown, a plurality of connecting rods 4 are fixedly connected to the outer surfaces of a plurality of rotating blocks 3 , and the connecting rods 4 can transfer the kinetic energy of the rotating blocks 3 moving downward to the slip rings 5 , so that the slip rings 5 move on the fixed rods 6 .
[0026] like Figure 1-4 As shown, two rotating shafts 14 are fixedly installed on the top inner surface of the shell 1, and the outer surfaces of the two rotating shafts 14 near the bottom are fixedly connected with multiple fan blades 15. The rotating shaft 14 can transfer the kinetic energy of the fan blades 15 to the incomplete gear 18 and the toothed wheel 13, so that the incomplete gear 18 and the toothed wheel 13 rotate.
[0027] like Figure 1-4 As shown, a plurality of air holes 16 are provided at the center of the bottom outer surface of the housing 1. The air holes 16 can lead out the heat inside the power control device to protect the stable operation of the internal equipment of the power control device.
[0028] like Figure 1-4 As shown, multiple cleaning plates 20 are fixedly connected to a limiting plate 21 on one side away from the tooth plate 19, and the limiting plate 21 and the top outer surface of the tooth plate 19 are fixedly connected to a sliding rod 22. The cleaning plates 20 can drive the bristles to clean the air holes 16 to avoid blockage of the air holes 16.
[0029] like Figure 1-4 As shown, a spring 23 is fixedly connected to the outer surface of one of the cleaning plates 20, and a fixing block 24 is fixedly connected to the end of the spring 23 away from one of the cleaning plates 20. The fixing block 24 is fixedly connected to the bottom outer surface of the shell 1. The spring 23 can provide power for the reverse movement of one of the cleaning plates 20 when the incomplete gear 18 is not engaged with the tooth plate 19, so that one of the cleaning plates 20 moves.
[0030] like Figure 1-4As shown, two slide grooves 17 are provided on the bottom outer surface of the shell 1, and two slide bars 22 are movably embedded in the inner surfaces of the slide grooves 17. The slide grooves 17 can limit the movement trajectory of the slide bars 22 to avoid derailment of the slide bars 22 and affect the use of the equipment.
[0031] Working principle: the power control device of the new energy vehicle is installed inside the shell 1. When encountering an uneven road section, the car body will vibrate, causing the shell 1 to move downward, and the shell 1 drives the multiple fixed blocks 2 to move downward. The multiple fixed blocks 2 drive the multiple rotating blocks 3 to move downward through the positioning pins, and the multiple rotating blocks 3 drive the multiple connecting rods 4 to move downward. Because the multiple slip rings 5 on the multiple connecting rods 4 are movably mounted with the two fixed rods 6 on the multiple fixed columns 7, the multiple connecting rods 4 will push the multiple slip rings 5 to move on the two fixed rods 6, and the springs 9 in the middle of the multiple slip rings 5 will release elastic potential energy to reduce the moving distance of the multiple slip rings 5 on the two fixed rods 6, thereby reducing the downward moving distance of the multiple connecting rods 4 and the multiple rotating blocks 3, which also reduces The multiple fixing blocks 2 and the distance for the shell 1 to move downward are reduced, and the car bottom plate 8 can support the fixing column 7, providing a good working environment for the fixing column 7. In this way, even if the car is traveling on an uneven road, it can also play a certain buffering role on the power control device, avoiding damage to the device and degradation of performance, and improving the service life of the device. Because the power control device is installed in an exposed position at the bottom of the vehicle, when the car is traveling at high speed, the wind at the bottom of the vehicle will exert a force and pressure on the multiple fan blades 2 15, causing the multiple fan blades 2 15 to rotate, and the multiple fan blades 2 15 will transfer this kinetic energy and pressure to the two rotating shafts 2 14, causing the two rotating shafts 2 14 to rotate, and the two rotating shafts 2 14 drive the two toothed wheels 13 through the two toothed wheels 13. 12 rotates, the two toothed wheels 12 drive the multiple fan blades 11 to rotate through the two rotating shafts 10, and the hot air inside the power control device is blown out through the multiple air holes 16, thereby reducing the temperature inside the power control device and protecting the normal operation of the power control device. At the same time, one of the rotating shafts 14 will drive the incomplete gear 18 to rotate, and the incomplete gear 18 drives the tooth plate 19 to move. The tooth plate 19 drives the limit plate 21 to move through the multiple cleaning plates 20. At the same time, the movement of one of the cleaning plates 20 will pull the spring 23, and the other end of the spring 23 is fixed on the fixed block 24, so the spring 23 will obtain elastic potential energy due to the movement of one of the cleaning plates 20, and the two slide bars on the limit plate 21 and the tooth plate 19 22 will move on the inner surfaces of the two slide grooves 17, providing a good working environment for the limit plate 21 and the tooth plate 19, and improving the service life of the limit plate 21 and the tooth plate 19. When the incomplete gear 18 is not engaged with the tooth plate 19, the spring 23 releases the elastic potential energy, pulling a cleaning plate 20 to move in the opposite direction. One cleaning plate 20 drives multiple cleaning plates 20 to move in the opposite direction through the tooth plate 19 and the limit plate 21, realizing the reciprocating motion of the cleaning plate 20. Because the bristles on the cleaning plate 20 fit with the air hole 16, the air hole 16 can be cleaned when the cleaning plate 20 reciprocates. In this way, the air hole 16 can be cleaned while dissipating heat, thereby avoiding the increase of the internal temperature of the power control device and ensuring the stable operation of the power control device.
