However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] The active cooling mechanism 3 includes a water tank 301, which can provide a liquid storage space. The top of the water tank 301 is fixedly connected to the bottom of the housing 2. Two mounting rings 302 are fixedly connected to the inner side of the water tank 301. The mounting rings 302 can provide a mounting position. An air-cooling cooling fan 303 is arranged on the inner side of the mounting ring 302. The air-cooling cooling fan 303 can generate wind force, and then can achieve air-cooling heat dissipation. A stable mounting shell 304 is fixedly connected to the inside of one of the mounting rings 302. The stable mounting shell 304 is fixedly connected to the inner side of the mounting ring 302. 04 can provide a stable installation position, the interior of the stable installation shell 304 is fixedly connected with a liquid pump head 305, the input shaft of the liquid pump head 305 is fixedly connected to the bottom of the air-cooled cooling fan 303, the input end of the liquid pump head 305 is fixedly connected with a water inlet pipe 306, the water inlet pipe 306 can provide conditions for liquid flow, the output end of the liquid pump head 305 is fixedly connected with a cooling heat dissipation pipe 307, the cooling heat dissipation pipe 307 can make the liquid flow heat conduction, and then can achieve the effect of heat dissipation, the interior of the shell 2 A heat-conducting fitting ring 308 is fixedly connected, a dust-proof plate 309 is fixedly connected to the inner bottom of the mounting ring 302, a cooling heat dissipation pipe 307 is arranged on the outside of the heat-conducting fitting ring 308, and an anti-skid pad is arranged on the inner side of the heat-conducting fitting ring 308. The end of the water inlet pipe 306 away from the liquid pump head 305 passes through the inner wall of the mounting ring 302, and the cooling heat dissipation pipe 307 passes through the bottom of the housing 2. The air-cooling cooling fan 303 is started. After the air-cooling cooling fan 303 rotates, the wind force generated can be used for air cooling and heat dissipation of the motion control device 1. When one of the air-cooling fans 303 rotates, it can drive the input shaft of the liquid pump head 305 to rotate, and then the liquid pump head 305 can have the function of pumping water.

The driving rotating rod 402 and the driven rotating rod 403 are fixedly connected with stirring heat dissipation blades 404 on their exteriors. After the stirring heat dissipation blades 404 rotate, the liquid inside the water tank 301 can be stirred, thereby accelerating the heat dissipation of the liquid inside the water tank 301. The stirring heat dissipation blades 404 are arranged inside the water tank 301. The bottom of the water tank 301 is fixedly connected with a protective shell 405. The protective shell 405 has a protective function to prevent the belt 2 from The rotation of the water tank 301 can prevent the user from being injured, and at the same time, it can protect the structure inside the shell 405.

When rotating, it can drive the active rotating rod 401 to rotate. The active rotating rod 401 rotates and drives the rotating rod 402 to rotate through the belt 2. After the rotating rod 402 rotates, it drives the driven rotating rod 403 to rotate through the belt 1, and then it can drive the two stirring heat dissipation blades 404 to rotate, and then accelerate the heat dissipation of the liquid in the water tank 301 by stirring the liquid in the water tank 301. At the same time, it can accelerate the heat dissipation of the water tank 301 again through the heat conductive sheet 407, and then have a better heat dissipation effect.

[0025] The mounting mechanism 5 includes an installation card compartment 501, which provides conditions for card installation. The top of the installation card compartment 501 is fixedly connected to the bottom of the motion control device 1. The side of the installation card compartment 501 away from the housing 2 is fixedly connected with a fixed installation box 502, which provides a sliding and installation space. The interior of the fixed installation box 502 is slidably connected with a sliding limit plate 503, which has a limiting function. The side of the sliding limit plate 503 close to the housing 2 is fixedly connected with a stop block 5. 04, a pressing sliding plate 505 is fixedly connected to the side of the sliding limit plate 503 away from the shell 2, and a locking elastic sheet 506 is fixedly connected to both sides of the outside of the shell 2. The abutting block 504 can press the locking elastic sheet 506 to force the locking elastic sheet 506 to deform, so that the locking elastic sheet 506 can be pulled out from the inside of the mounting locking bin 501. The pressing sliding plate 505 penetrates the side of the fixed mounting box 502 away from the shell 2, and the abutting block 504 penetrates the side of the mounting locking bin 501 close to the shell 2. The housing 2 is provided with a protective pad. When installing the housing 2, first align the snap-fit ​​elastic sheet 506 with the bottom of the mounting snap-fit ​​compartment 501 and push it in. When the snap-fit ​​elastic sheet 506 contacts the inner wall of the bottom of the mounting snap-fit ​​compartment 501, since the snap-fit ​​elastic sheet 506 is an inclined surface, it is deformed toward the housing 2 under the pressure of the bottom of the mounting snap-fit ​​compartment 501. When the bottom of the snap-fit ​​elastic sheet 506 enters the interior of the mounting snap-fit ​​compartment 501, it is reset under the elastic action of the snap-fit ​​elastic sheet 506, and then the snap-fit ​​elastic sheet 506 can be used. The bottom of 6 is engaged with the bottom of the installation engaging bin 501 to complete the installation of the shell 2. When the shell 2 needs to be removed, the sliding plate 505 is pressed to drive the sliding limit plate 503 and the abutting block 504 to move in the direction of the shell 2, and then the abutting block 504 can be used to squeeze the engaging elastic sheet 506, forcing the engaging elastic sheet 506 to deform, and the shell 2 can be pulled out at this time. At this time, the engaging elastic sheet 506 can also leave the interior of the installation engaging bin 501, and then the shell 2 can be removed.

[0026] Working principle: When the motion controller actively dissipates heat, the air-cooling fan 303 is started. After the air-cooling fan 303 rotates, the wind force generated can be used to cool the motion control device 1. At the same time, after one of the air-cooling fans 303 rotates, it can drive the input shaft of the liquid pump head 305 to rotate, so that the liquid pump head 305 can have the function of pumping water. The liquid enters the interior of the liquid pump head 305 through the water inlet pipe 306, and enters the interior of the cooling pipe 307 through the output end of the liquid pump head 305, and dissipates the heat for the thermal conductive bonding ring 308. At the same time, the heat conduction of the thermal conductive bonding ring 308 allows the internal heat of the motion control device 1 to be dissipated, thereby combining liquid cooling and air cooling. When the other air-cooling fan 303 rotates, it can drive the active rotating rod 401 to rotate. The active rotating rod 401 rotates and drives the rotating rod 402 to rotate through the second belt. After the rotating rod 402 rotates, the driven rotating rod 403 is driven to rotate through the first belt, and then the two stirring heat dissipation blades 404 are driven to rotate, and then the heat dissipation of the liquid in the water tank 301 is accelerated by stirring the liquid in the water tank 301. At the same time, the heat dissipation of the water tank 301 can be accelerated again through the heat conducting sheet 407, and then a better heat dissipation effect can be achieved. When installing the housing 2, first align the engaging elastic sheet 506 with the bottom of the mounting engaging compartment 501 and push it in. When the engaging elastic sheet 506 contacts the inner wall of the bottom of the mounting engaging compartment 501, since the engaging elastic sheet 506 is an inclined surface, it is deformed toward the housing 2 under the pressure of the bottom end of the mounting engaging compartment 501. When the bottom of the engaging elastic sheet 506 enters the interior of the mounting engaging compartment 501, it is reset under the elastic action of the engaging elastic sheet 506, and then the bottom engaging sheet 506 can be used to engage the housing 2. The bottom of the mounting snap-fitting compartment 501 is engaged to complete the installation of the shell 2. When the shell 2 needs to be removed, the sliding plate 505 is pressed, and the sliding plate 505 drives the sliding limit plate 503 and the abutting block 504 to move in the direction of the shell 2, and then the abutting block 504 can be used to squeeze the engaging elastic sheet 506, forcing the engaging elastic sheet 506 to deform, and the shell 2 can be pulled out at this time. At this time, the engaging elastic sheet 506 can also leave the interior of the mounting snap-fitting compartment 501, and then the shell 2 can be removed.
