[0022] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this utility model to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and with various changes and modifications based on the following embodiments.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] See Figure 1-6 In this embodiment of the present invention, a servo motor for easy heat dissipation includes a motor body 1. The bottom two ends of the motor body 1 are connected to a mounting frame 3 via mounting bases 2. The top front and rear ends of the mounting frame 3 are stably clamped to the top of the motor body 1 by a number of clamping components. A first heat dissipation groove 7 is provided on the side wall of the front and rear ends of the motor body 1. A moving pushing mechanism for heat diffusion is installed on the inner wall of the mounting frame 3. A motor shaft 12 is rotatably mounted at the center of the side wall of the motor body 1. A second heat dissipation groove 22 is provided on the motor body 1 outside the motor shaft 12. A protective cover 13 is provided on the motor body 1 outside the second heat dissipation groove 22. A sliding groove 16 is provided on the inner wall of the protective cover 13. Rotating components 15 are provided at both ends of the motor shaft 12 inside the protective cover 13. The rotating components 15 are slidably disposed inside the sliding groove 16. A number of heat dissipation holes 17 are provided at equal intervals on the protective cover 13 outside the sliding groove 16. A sealing component for sealing the heat dissipation holes 17 is installed on the heat dissipation holes 17.

[0026] This invention provides protection for the servo motor by setting a mounting frame 3 on the motor body 1. During operation, the motor body 1 is cooled by the first heat dissipation groove 7. The moving and pushing mechanism allows the cooled air to exit from the mounting frame 3, thus achieving rapid heat dissipation for the servo motor. The second heat dissipation groove 22 is protected by a protective cover 13, which stores the cooled air inside the protective cover 13. During operation, the motor shaft 12 drives the rotating component 15 to rotate. The rotating component 15 rotates inside the sliding groove 16, pushing the sealing assembly to open the heat dissipation hole 17, thereby cooling the air inside the protective cover 13.

[0027] See Figure 3 In one embodiment of this utility model, the clamping assembly includes a clamping screw 4 threadedly connected to the top of the mounting frame 3. A rotating disk 5 is provided at the top of the clamping screw 4, and a clamping block 6 is provided at the bottom of the clamping screw 4. By manually rotating the rotating disk 5, the rotating disk 5 drives the clamping screw 4 to rotate and move downward. The clamping screw 4 drives the clamping block 6 to clamp the top of the motor body 1, thus achieving a stable connection between the motor body 1 and the mounting frame 3.

[0028] See Figure 2 In one embodiment of this utility model, the moving pushing mechanism includes fixed blocks 8 fixedly installed at the four corners of the mounting frame 3. The fixed blocks 8 are connected to the moving plate 11 through a moving drive assembly. The moving drive assembly drives the moving plate 11 to move, and the moving plate 11 pushes out the air dissipated inside the first heat dissipation groove 7 by reciprocating movement, thereby facilitating the rapid heat dissipation of the servo motor.

[0029] See Figure 2 In one embodiment of this utility model, the moving drive assembly includes a drive part 9 fixedly connected to the fixed block 8. A one-way screw 10 is mounted on the output shaft of the drive part 9. The end of the one-way screw 10 is rotatably connected to the fixed block 8. The one-way screw 10 is threadedly connected to the moving plate 11. The drive part 9 drives the one-way screw 10 to rotate. The one-way screw 10 drives the threaded moving plate 11 to perform reciprocating motion, thereby facilitating rapid heat dissipation of the first heat dissipation groove 7.

[0030] See Figure 2 In one embodiment of this utility model, a sealing sleeve 14 is provided at the connection between the motor shaft 12 and the protective cover 13. The sealing sleeve 14 can realize the sealed rotation between the motor shaft 12 and the protective cover 13, thereby facilitating the sealing and protection of the servo motor.

[0031] See Figure 4 In one embodiment of this utility model, the sealing assembly includes an external sealing block 18 disposed outside the heat dissipation hole 17. The external sealing block 18 is connected to a spherical sealing member 20 via a connecting rod 19. The inner end of the spherical sealing member 20 is inserted into the sliding groove 16, and the spherical sealing member 20 seals the opening of the inner end of the heat dissipation hole 17. The heat dissipation hole 17 is connected to the external sealing block 18 via a return spring 21. During the rotation of the rotating member 15, the rotating member 15 pushes the spherical sealing member 20 to move outward. The spherical sealing member 20 opens the opening of the external sealing block 18 and the heat dissipation hole 17 via the return spring 21, allowing the air inside the protective cover 13 to be discharged. This facilitates the discharge of heat from inside the protective cover 13. The return spring 21 is compressed to generate elastic force, which can reset the external sealing block 18 and the spherical sealing member 20, thereby facilitating the heat dissipation of the servo motor.

[0032] Working Principle: The bottom ends of the motor body 1 of this utility model are connected to the mounting frame 3 via mounting base 2. The mounting frame 3 provides safety protection for the servo motor. During the operation of the servo motor, the first heat dissipation groove 7 dissipates the heat generated inside the motor body 1. The dissipated air diffuses to the front ends of the mounting frame 3 and is driven by the drive unit 9. The drive unit 9 drives the one-way screw 10 to rotate. The one-way screw 10 drives the threaded moving plate 11 to reciprocate. The moving plate 11 dissipates the hot air through the openings at both ends of the mounting frame 3, thus achieving rapid heat dissipation in the first heat dissipation groove 7. During the operation of the motor body 1, the motor body 1 drives the motor shaft 12 to rotate. The motor shaft 12 drives the rotating part 15 to rotate inside the sliding groove 16. The rotating part 15 pushes the spherical sealing part 20 to move outward, opening the heat dissipation hole 17 and the sliding groove 16. The hot air inside the protective cover 13 is discharged to the outside of the protective cover 13, thus achieving rapid heat dissipation for the servo motor.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
