[0007] Furthermore, a control assembly is arranged on the outer side of the upper shell, and the control assembly includes a second motor fixedly mounted on the front end surface of the upper shell and an eccentric wheel fixedly connected to the output end of the second motor.

[0008] Furthermore, the four first dustproof nets are in a group of two, and each group of first dustproof nets is in a symmetrical structure and is embedded in the lower shell.

[0009] Furthermore, the output end of the temperature detector passes through the upper shell and extends into the interior thereof, and one end of the second limiting rod is vertically fixedly connected to the inner wall surface of the lower shell.

[0017] 2. The servo drive housing with efficient heat dissipation can monitor the heat energy conditions in the lower housing and the upper housing in real time through a temperature detector. When the heat energy is higher than the value set in the temperature detector, the second motor is started to rotate the eccentric wheel to separate it from the lower side of the movable plate, and then the movable plate is separated from the lower surface of the second dustproof net, so that a large amount of gas entering can quickly combine and disperse the heat energy generated by the component, thereby improving the heat dissipation efficiency. When the heat energy is lower than the value set in the temperature detector, the end of the eccentric wheel will contact the lower side of the movable plate and fit with the lower surface of the second dustproof net, thereby controlling the fluidity of the gas, solving the problem that there is no dustproof net structure between the base and the top cover, the installation slot position will be expanded during movement, causing a large amount of dust in the air to enter and adhere to the surface of the component, and there is no detection structure for the temperature inside the base and the top cover, and it is impossible to judge whether the internal temperature requires the base and the top cover to be separated to improve the heat dissipation effect.

[0022] Among them, a control component is arranged on the outside of the upper shell 3, and the control component includes a second motor 16 fixedly mounted on the front end surface of the upper shell 3 and an eccentric wheel 11 fixedly connected to the output end of the second motor 16.

[0023] It should be noted that the temperature detector 15 is a PT100 resistance temperature sensor, which has high accuracy, good stability and strong anti-interference ability.

[0024] When this embodiment is used: Component 6 is installed on the upper side of the mounting base 5, and the upper shell 3 is clamped on the upper side of the lower shell 2. The first motor 14 is started to drive the first gear 23. The belt 17 drives the first gear 9 on the outer side of the first rotating shaft 8 to synchronously mesh with the first gear 23 on the outer side of the second rotating shaft 22 to rotate, and the turntable 25 will drive the first connecting rod 28 and the connecting rope 27 to move synchronously. The first connecting rod 28 drives the first sleeve 30 and the heat dissipation fan 32 to move laterally on the outer side of the second limiting rod 31 through the second connecting rod 29. The connecting rope 27 moves to one side of the fixed box 21 due to the rotation of the turntable 25, and the cleaning brush 37 moves on one side of the surface of the second dustproof net 7 to clean part of the dust. The spring 34 extends its own length. When the first motor 14 rotates to the other side, the turntable 25 loosens the connecting rope 27 and cooperates with the spring 34 to rebound to move the second sleeve 35 to the other side of the second dustproof net 7 to clean the remaining dust. The first connecting rod 28 cooperates with the second connecting rod 29 to drive the second connecting rod 29 to move the second sleeve 35 to the other side of the second dustproof net 7. A sleeve 30 slides toward the other end of the second limiting rod 31 to expand the heat dissipation range of the component 6. External air enters from the second dustproof net 7, and then after filtering out dust, it combines with the heat dissipation fan 32 from the exhaust hole 19, and is then discharged to the surface of the component 6 by the heat dissipation fan 32. After combining with the heat energy, it is discharged and blown away from the first dustproof net 4, thereby reducing the heat around the component 6 to achieve heat dissipation. The temperature detector 15 will monitor the temperature inside the upper shell 3 and the lower shell 2 in real time. When the heat energy is higher than the value set in the temperature detector 15, the second motor 16 is started to rotate the eccentric wheel 11 to separate from the lower side of the movable plate 18, and then the movable plate 18 is separated from the lower surface of the second dustproof net 7, so that a large amount of gas entering can quickly combine and disperse the heat energy generated by the component 6, thereby improving the heat dissipation efficiency. When the heat energy is lower than the value set in the temperature detector 15, the end of the eccentric wheel 11 will contact the lower side of the movable plate 18 and fit with the lower surface of the second dustproof net 7, thereby controlling the fluidity of the gas. The beneficial effects of the above embodiments are: The servo drive housing with efficient heat dissipation drives the heat dissipation fan 32 to move back and forth laterally at the upper end of the component 6 through the first connecting rod 28 and the second connecting rod 29, so as to quickly dissipate the heat energy on the surface of the component 6. The reciprocating rotation of the turntable 25 can also drive the second sleeve 35 connected to the connecting rope 27 to move back and forth on the surface of the second dustproof net 7, and can automatically clean up the dust filtered on the upper side of the second dustproof net 7.

[0025] The servo drive housing with efficient heat dissipation can monitor the heat energy conditions in the lower housing 2 and the upper housing 3 in real time through the temperature detector 15. When the heat energy is higher than the value set in the temperature detector 15, the second motor 16 is started to rotate the eccentric wheel 11 to separate it from the lower side of the movable plate 18, and then the movable plate 18 is separated from the lower surface of the second dustproof net 7, so that a large amount of gas entering the component 6 can be quickly combined and dispersed to improve the heat dissipation efficiency. When the heat energy is lower than the value set in the temperature detector 15, the end of the eccentric wheel 11 will contact the lower side of the movable plate 18 and fit with the lower surface of the second dustproof net 7, so as to control the fluidity of the gas, and solve the problem that there is no dustproof net structure between the base and the top cover, the installation slot position will be expanded during movement, causing a large amount of dust in the air to enter and adhere to the surface of the component, and there is no detection structure for the temperature inside the base and the top cover, and it is impossible to judge whether the internal temperature requires the base and the top cover to be separated to improve the heat dissipation effect.
