[0002] In order to make the new energy vehicle motor work stably, the heat generated during the operation of the new energy vehicle motor needs to be dissipated in time to make the motor run more stably. At the same time, the heating temperature of the motor needs to be monitored and controlled to ensure the normal and safe operation of the new energy vehicle motor and extend its service life.

[0003] At present, the heating temperature of new energy vehicle motors changes dynamically with different usage conditions and environments, which requires good monitoring of the heating temperature of the vehicle motors.

The eddy current disk 53 is sleeved on the outside of the electromagnet 52. A movable cavity is opened on the side of the movable sleeve 54 close to the limit tube 58. An inner tooth block 540 is fixedly connected to the inner wall of the movable cavity. An outer tooth block 541 is fixedly connected to the outer wall of the movable sleeve 54. The third gear 56 is rotatably installed on the monitoring box 50, and the third gear 56 is arranged below the movable sleeve 54. When the driving block 24 and the inner tooth block 540 are against each other, the outer tooth block 541 is meshed with the teeth on the outer surface of the third gear 56. When the driving block 24 and the inner tooth block 540 are separated from each other, the outer tooth block 541 and the third gear 56 are also separated synchronously. A magnet seat is also fixedly installed on the limit seat 51. The movable sleeve 54 is a metal sleeve, specifically an iron plate, and the metal plate is an iron plate. When the driving block 24 and the inner tooth block 540 are against each other, the outer tooth block 541 and the third gear 56 are also separated synchronously. When the inner gear block 540 is against each other, the movable sleeve 54 is in contact with the magnet seat. It should be noted that the magnetic force of the magnet seat is much smaller than the magnetic force of the electromagnet. Therefore, when the electromagnet is energized, the movable sleeve will be adsorbed by the electromagnet and the movable sleeve will be separated from the magnet seat. A through hole 57 is provided at the bottom of the monitoring box 50. The bottom of the third gear 56 is provided on the outside of the monitoring box 50. A controller, a first relay and a second relay are provided inside the control unit 59. The first relay and the electromagnet 52 are located in the same control circuit. The first relay is used to control the power on and off of the electromagnet 52. The second relay and the eddy current disk 53 are located in the same control circuit. The second relay is used to control the power on and off of the eddy current disk 53. During use, the cooling fan 44 remains energized.The automobile motor 2 is well cooled. When the temperature monitored by the temperature sensor 43 is within a reasonable range, the control unit 59 uses the first relay to control the electromagnet 52 to be energized, and the second relay controls the eddy current disk 53 to be deenergized. At this time, the electromagnet 52 has strong magnetism and can adsorb the metal plate 55, so that the metal plate 55 fits with the surface of the electromagnet 52, thereby driving the movable sleeve 54 to move right, so that the drive block 24 and the inner gear block 540 are separated from each other. At this time, the outer gear block 541 and the third gear 56 are also separated synchronously, so as to avoid the motor shaft 21 of the automobile motor 2 from driving the drive shaft 23 and the movable sleeve 54 to rotate when the motor shaft 21 of the automobile motor 2 is working and rotating, thereby avoiding the second gear 33 of the linkage mechanism 3 from rotating. At this time, the heat dissipation ring 41 will not rotate. When the temperature monitored by one of the temperature sensors 43 exceeds its preset temperature value, it means that the motor temperature in this area is too high, and the normally operating heat dissipation fan 44 cannot dissipate heat well for it. Therefore, when the control unit 59 receives the telecommunication signal that its temperature is too high, the heat dissipation fan 44 cannot dissipate heat well for it. When the signal is on, the first relay controls the electromagnet 52 to be powered off, and the second relay controls the eddy current disk 53 to be powered on. An eddy current repulsion coil is arranged in the eddy current disk 53, which discharges instantaneously to the eddy current repulsion coil, and generates a repulsive force by the principle of electromagnetic induction, so that the metal plate 55 moves to the left. When the metal plate 55 drives the movable sleeve 54 to move to the position of the limit seat 51, the limit seat 51 limits its position. At this time, the inner gear block 540 on the movable sleeve 54 is just in the same plane with the driving block 24, and at this time, the outer gear block 541 is also in the same plane with the teeth of the third gear 56. When the drive shaft 23 rotates, it drives the driving block 24 to move, thereby driving the inner gear block 540 to move in a circle, thereby driving the movable sleeve 54 to rotate. The rotating movable sleeve 54 uses the outer gear block 541 to intermittently drive the third gear 56 to rotate, so as to realize the rotation drive of the heat dissipation ring 41 of the heat dissipation unit 4, thereby realizing the displacement of the heat dissipation fan, realizing the heat dissipation treatment of different areas of the automobile motor by the heat dissipation fan, and improving the heat dissipation effect. ,
