[0013] The beneficial effects of the present invention are: 1. The present invention provides a heat dissipation mechanism. When the driver is subjected to heat dissipation treatment, the air cooler is started, and the air cooler performs heat dissipation treatment on the inside of the driver. The cold air blown by the air cooler acts on the blades, and the blades drive the rotating rod to rotate when rotating. At this time, the second top block rotates with the rotation of the rotating rod. Therefore, through the cooperation between the first top block and the second top block, the second top block pushes the first top block upward when rotating, and the first top block drives the top plate to move synchronously when moving upward, and the top plate squeezes the airbag when moving. At this time, the gas inside the airbag will be ejected upward through the air jet after being squeezed. At this time, the hot air inside the driver will flow upward quickly under the jet action of the airflow, so as to be discharged through the heat dissipation holes. During the process, when the rotating rod rotates, the cooperation between the two pulleys and the belt causes the rotating shaft to drive the shaft rod to rotate, thereby the meshing between the two gears causes the support rod to drive the impeller to rotate, thereby blowing the cold air upward through the impeller, and then the cold air is used to dissipate heat inside the driver, and the compression component accelerates the discharge of hot air, and the cold air is quickly blown to the inside of the driver through the exhaust component. The cooperation between the compression component and the exhaust component can effectively dissipate heat inside the driver, so as to improve the heat dissipation effect of the driver, and prevent the delivered cold air from merging with the heat inside the driver due to the fact that the heat inside the driver is not effectively discharged, thereby increasing the temperature of the cold air, and then affecting the heat dissipation effect of the driver; 2. The present invention provides a heat dissipation mechanism and a swinging mechanism. When the heat dissipation mechanism is used to dissipate heat inside the driver, the protrusion will rotate synchronously with the rotation of the shaft. Since the protrusion is L-shaped, the protrusion will rotate with the center of the shaft as the center. At this time, the push rod will push one end of the swing plate to reciprocate under the action of the protrusion and the sleeve. Since the two swing plates are distributed in an eight-shaped shape, cold air will flow upward through the two swing plates. When the swing plates are reciprocating, the swing plates will accelerate the flow rate of cold air to improve the heat dissipation effect of the cold air on the driver, and prevent the temperature of the cold air from being lost due to the slow flow rate of the cold air, thereby affecting the heat dissipation effect of the driver.

[0022] Example 2, reference Figure 1-7 , a heat dissipation device for an intelligent servo drive system. Compared with Example 1, on the basis of Example 1, two swing mechanisms 21 are arranged inside the cabinet 1, and the swing mechanism 21 is matched with the heat dissipation mechanism, and the two swing mechanisms 21 are distributed on both sides of the cabinet 1.

[0023] On the basis of the above, the swing mechanism 21 includes a protrusion 34, a swing plate 37, a push rod 36 and a sleeve 35, and one end of the protrusion 34 is welded to the shaft rod 33, the shape of the protrusion 34 is L-shaped, and the sleeve 35 is rotatably sleeved on the outer wall of the protrusion 34, one side of the swing plate 37 is connected to the inner wall of one side of the cabinet 1 by a hinge, and the two ends of the push rod 36 are respectively connected to the swing plate 37 and the sleeve 35 by hinges, and the two swing plates 37 are distributed in an eight-shaped shape. When the swing plate 37 is reciprocatingly deflected, the swing plate 37 will accelerate the flow rate of cold air, so as to improve the heat dissipation effect of cold air on the driver, and prevent the temperature of cold air from being lost due to the slow flow rate of cold air, thereby affecting the heat dissipation effect of the driver.

[0024] In summary, with the aid of the above technical solution of the present invention: when the driver is subjected to heat dissipation treatment, the air cooler 9 is started, the air cooler 9 will perform heat dissipation treatment on the inside of the driver, and the cold air blown by the air cooler 9 will act on the blades 26, and the blades 26 will drive the rotating rod 24 to rotate when rotating. At this time, the second top block 23 will rotate with the rotation of the rotating rod 24. Therefore, through the cooperation between the first top block 22 and the second top block 23, the second top block 23 will push the first top block 22 upward when rotating, and the first top block 22 will drive the top plate 17 to move synchronously when moving upward, and the top plate 17 When moving, the airbag 20 will be squeezed. At this time, the gas inside the airbag 20 will be ejected upward through the jet port 16 after being squeezed. At this time, the hot air inside the driver will flow upward quickly under the jet of the airflow, and then be discharged through the heat dissipation hole 4. During this period, when the rotating rod 24 rotates, the rotating shaft 27 drives the shaft rod 33 to rotate through the cooperation between the two pulleys 30 and the belt 31, so that the support rod 29 drives the impeller 32 to rotate through the meshing between the two gears 28, so that the cold air is blown upward through the impeller 32, and then the inside of the driver is cooled by the cold air. The compression component 13 accelerates the discharge of hot air, and the exhaust component 11 quickly blows cold air to the interior of the driver. The cooperation between the compression component 13 and the exhaust component 11 can effectively dissipate heat inside the driver, so as to improve the heat dissipation effect of the driver and prevent the heat inside the driver from being effectively discharged, resulting in the cold air being transported and the heat inside the driver merging, thereby increasing the temperature of the cold air and affecting the heat dissipation effect of the driver. When the heat dissipation mechanism is used to dissipate heat inside the driver, the protrusion 34 will rotate synchronously with the rotation of the shaft 33. Since the shape of the protrusion 34 is L-shaped, the protrusion 34 will rotate with the center of the shaft 33 as the center. At this time, the push rod 36 will push one end of the swing plate 37 to reciprocate under the action of the protrusion 34 and the sleeve 35. Since the two swing plates 37 are distributed in an eight-shaped shape, the cold air will flow upward through the two swing plates 37. When the swing plates 37 reciprocate, the swing plates 37 will accelerate the flow speed of the cold air to improve the heat dissipation effect of the cold air on the driver, and prevent the temperature of the cold air from being lost due to the slow flow rate of the cold air, thereby affecting the heat dissipation effect of the driver.
