In addition, the linkage mechanism 3 is driven by the third gear 56 of the heat monitoring unit 5, which can drive the heat dissipation unit 4 to rotate outside the automobile motor 2, thereby further improving the heat dissipation control of various areas of the automobile motor by the cooling fan 44.

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 limiting tube 58. The inner wall of the movable cavity is fixedly connected to the inner gear block 540. The outer wall of the movable sleeve 54 is fixedly connected to the outer gear block 541. The third gear 56 is rotatably mounted 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 gear block 540 are against each other, the outer gear block 541 is meshed with the teeth on the outer surface of the third gear 56. When the driving block 24 and the inner gear block 540 are disengaged from each other, the outer gear block 541 and the third gear 56 are also disengaged synchronously. A magnet seat is also fixedly mounted on the limiting seat 51. The movable sleeve 54 is a metal sleeve, specifically an iron plate. The metal plate is an iron plate. When the driving block 24 and the inner gear block 540 are disengaged, the outer gear block 541 and the third gear 56 are also disengaged synchronously. When the inner gear blocks 540 are 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 attracted 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 heat dissipation around the automobile motor 2 is good. 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 to control the eddy current disk 53 to be de-energized. At this time, the electromagnet 52 has strong magnetism and can adsorb the metal plate 55, so that the metal plate 55 fits 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, thereby preventing the motor shaft 21 of the automobile motor 2 from driving the drive shaft 23 and the movable sleeve 54 to rotate when working, thereby preventing 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 cooling fan 44 cannot dissipate heat well. Therefore, when the control unit 59 receives the electrical signal that its temperature is too high, the motor 20 is turned off. When the signal is received, the first relay controls the electromagnet 52 to be de-energized, and the second relay controls the eddy current disk 53 to be energized. An eddy current repulsion coil is provided in the eddy current disk 53, which discharges instantaneously to the eddy current repulsion coil. The repulsive force is generated by the principle of electromagnetic induction, causing the metal plate 55 to move 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 exactly in the same plane as the drive block 24, and the outer gear block 541 is also in the same plane as the teeth of the third gear 56. When the drive shaft 23 rotates, it drives the drive block 24 to move, thereby driving the inner gear block 540 to move in a circular motion, 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, which can realize the rotational drive of the heat dissipation ring 41 of the heat dissipation unit 4, thereby realizing the displacement of the cooling fan, and realizing the cooling fan to dissipate heat in different areas of the automobile motor, thereby improving the cooling effect. ,
