[0002] With the widespread application of automated equipment and precision control systems, servo motors, as core actuators, are widely used in various fields such as machinery manufacturing, automation control, medical devices, and aerospace. Especially when used outdoors or in humid environments, the protective performance of servo motors is crucial to the stable operation of the entire system. Therefore, developing servo motor structures with excellent protective performance has become an important research direction.
[0003] Existing servo motors typically employ traditional sealed housings for protection, primarily relying on sealing rings, end cap structures, and external coatings to achieve waterproofing, dustproofing, and corrosion resistance. Additionally, to reduce damage to the motor body from external impacts or vibrations, a buffer layer or elastic damping structure is generally installed around the motor housing. However, in existing technologies, the overall sealing and damping effects are insufficient, leading to malfunctions due to moisture infiltration during use. Furthermore, the buffer structure's response to vibration and impact is often slow, failing to effectively mitigate the impact and causing damage to the motor body. Therefore, a waterproof servo motor structure is proposed to address these issues. Utility Model Content

[0008] Furthermore, the adjustment assembly includes a lead screw and a return spring.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figures 1-5This utility model provides an embodiment of a waterproof servo motor structure, including a base plate 1. A sealing cover 3 is provided on one side of the upper surface of the base plate 1 to cover and protect the motor body 6. The motor body 6 is provided on the upper surface of the base plate 1. The motor body 6 is a servo control execution component. A sealing assembly is provided between the base plate 1 and the sealing cover 3 to achieve a sealing and protective function between the bottom and the cover, preventing water vapor from seeping in. A shock-absorbing assembly is installed inside the sealing cover 3 to absorb external impacts and vibrations, protecting the stable operation of the motor body 6. The shock-absorbing assembly includes a hinge block 7, a limit rod 8, and a slider 10. The hinge block 7, along with the spring damping rod 11, is fixedly connected to the inner wall of the sealing cover 3 on one side of its outer wall, serving as a fixed base for the shock absorption assembly. One end of the limiting rod 8 is fixedly connected to the outer wall of the hinge block 7, providing a sliding track for the slider 10. The inner wall of the slider 10 is slidably connected to the outer wall of the limiting rod 8, achieving a buffering action through sliding. A spring damping rod 11 is fixedly connected between the hinge block 7 and the slider 10, providing damping and rebound force to effectively absorb external vibration energy. A rotating plate 12 is rotatably connected to one side of the inner wall of the slider 10, converting the linear sliding motion of the slider 10 into... Angle displacement further absorbs impact energy; a hinge seat 14 is rotatably connected to the outer wall of the rotating plate 12, and a buffer plate 15 is fixedly connected to one side of the outer wall of the hinge seat 14. One side of the outer wall of the buffer plate 15 abuts against the outer wall of the motor body 6, playing a buffering and shock-absorbing role and preventing the motor body 6 from being directly subjected to force; a return spring 9 is sleeved on the outer wall of the limit rod 8, which is used to automatically reset the slider 10 after the buffering action; an adjustment component is installed on one side of the outer wall of the hinge seat 14, which is used to finely adjust the buffering force and the limit range as needed; the sealing component includes a sealing plate 12 and a sealing plate 2. 4. The lower surface of sealing plate 2 is fixedly connected to one side of the upper surface of the base plate 1, serving as a bottom sealing support structure; the upper surface of sealing plate 4 is fixedly connected to the top of the inner wall of the sealing cover 3, serving as an upper sealing support structure; a sealing block 5 is fixedly connected to one side of the outer wall of sealing plate 4, and the outer wall of sealing block 5 is provided with a structure that can slide and cooperate with the inner wall of sealing plate 2. By slidingly connecting the outer walls of sealing plate 4 and sealing block 5 inside sealing plate 2, a sliding sealing structure with upper and lower cooperation is formed, which further improves the overall sealing performance, effectively prevents water vapor from entering the motor, and improves the overall protection level.
[0026] Specifically, by setting a sealing component between the base plate 1 and the sealing cover 3, overall sealing and waterproof protection is achieved, preventing rainwater and moisture from entering the motor cavity and ensuring stable operation of the servo motor in complex environments. The buffer plate 15, by contacting the motor body 6 and cooperating with the slider 10, spring damping rod 11, and rotating plate 12, can effectively disperse and absorb the impact force when the motor is subjected to external impact. At the same time, the slider 10 drives the return spring 9 to deform and release the buffer energy, thereby reducing the direct impact on the motor body 6, significantly improving the impact resistance and service life of the motor body, and enhancing the practicality and reliability of the whole machine.
[0027] Reference Figures 1-5The adjustment assembly includes a lead screw 16 and a return spring 17. The lead screw 16 is used to adjust the position of the positioning block 13 to control the buffer strength. One end of the return spring 17 is fixedly connected to one side of the outer wall of the hinge seat 14, and the other end is fixedly connected to the positioning block 13 to provide a rebound force after the force is released. The outer wall of the hinge seat 14 is threadedly connected to the inside of the sealing cover 3 to realize the adjustable and fixed position of the hinge seat 14. One end of the lead screw 16 is rotatably connected to one side of the outer wall of the positioning block 13, which makes it easy to adjust the height and position of the positioning block 13 by rotating the lead screw 16, thereby improving the flexibility of structural adjustment. Multiple fixing blocks 18 are fixedly connected to one side of the outer wall of the sealing cover 3 as supporting components for positioning connection. Multiple mounting seats 25 corresponding to the fixing blocks 18 are fixedly connected to the upper surface of the base plate 1 for installing and cooperating with the structure of the fixing blocks 18 to achieve quick installation and positioning of the whole. Each of the multiple fixing blocks 18 has a positioning component fixedly connected inside. The positioning component is used to achieve a detachable connection between the sealing cover 3 and the base plate 1. The positioning component includes a rod 19, a second hinge seat 21, a second rotating plate 22, and a locking block 23. One side of the outer wall of the rod 19 is fixedly connected inside the fixing block 18 for sliding positioning in the mounting base 25. The second hinge seat 21 is located inside the rod 19 and provides a rotation fulcrum for the second rotating plate 22. One side of the outer wall of the second rotating plate 22 is rotatably connected to the inner wall of the second hinge seat 21 for driving the locking block 23 to rotate to open or lock. One side of the inner wall of the locking block 23 is rotatably connected to the other side of the outer wall of the second rotating plate 22. The outer wall of the locking block 23 passes through the rod 19 and is slidably connected inside the mounting base 25. When the locking block 23 is rotated and positioned, it can quickly lock or release the rod 19, thereby facilitating the disassembly and reassembly of the sealing cover 3. Installation: A return spring 20 is fixedly connected to the lower surface of the hinge seat 21. The lower end of the return spring 20 abuts against the bottom of the inner wall of the insert rod 19. It is used to automatically return the rotating plate 22 and the locking block 23 to the initial position after the locking block 23 is released, improving the convenience of repeated use. A lead screw 24 is threaded inside the insert rod 19. The lower surface of the lead screw 24 abuts against the upper surface of the hinge seat 21. By rotating the lead screw 24, the height of the hinge seat 21 can be finely adjusted, thereby accurately adjusting the fit between the locking block 23 and the mounting seat 25, improving the assembly accuracy and stability. The two ends of the return spring 9 abut against one side of the outer wall of the two sliders 10 respectively. By connecting the two sliders 10, it provides a rebound force when the sliders 10 are subjected to pressure and slides, while also assisting in achieving a buffer reset effect, further improving the reliability of the entire shockproof protection structure.
[0028] Specifically, by adjusting the lead screw 16 and the return spring 17 in the adjustment assembly, the position of the hinge seat 14 can be flexibly adjusted according to different usage requirements, thereby adjusting the damping effect and improving the adaptability of the servo motor in different application environments. The positioning assembly design formed by the fixing block 18, the insertion rod 19 and the mounting base 25 allows the sealing cover 3 to be quickly installed and removed, facilitating equipment maintenance and repair. The cooperation design between the return spring 20 and the lead screw 24 ensures the stable positioning and automatic reset of the locking block 23 during use, improving positioning reliability and ease of operation, thereby further enhancing the overall practicality and engineering reliability of the waterproof servo motor structure.
[0029] Working principle: When this waterproof servo motor structure is required, first place the motor body 6 on top of the base plate 1. Then, cover the motor body 6 with the sealing cover 3. Insert the sealing block 5 on the outside of the sealing plate 2 into the sealing plate 1, thus achieving a further sealing effect. Then, insert the rod 19 inside the fixing block 18 into the mounting base 25. Then, rotate the screw 24, which abuts against the hinge seat 21 and presses it towards the return spring 3 20. The movement of the hinge seat 21 then drives the locking block 23 on the outside of the rotating plate 22 to insert into the mounting base 25 for fixation. When the sealing cover 3 encounters a collision, the buffer plate 15 receives the pressure and drives the hinge seat 1 The internal rotating plate 12 rotates, which in turn drives the slider 10 to compress the spring damping rod 11 and reduce pressure. The slider 10 then slides on the outer wall of the limiting rod 8, which stretches the reset spring 9, further reducing pressure. The screw 16 rotates, which in turn drives the reset spring 17 to extend and retract, while simultaneously adjusting the buffer plate 15 on one side of the hinge seat 14. When disassembling the sealing cover 3, the screw 24 is turned to remove the insert rod 19. The reaction force of the reset spring 20 facilitates the lifting of the hinge seat 21. The hinge seat 21 then drives the locking block 23 on one side of the rotating plate 22, thus achieving the effect of quickly disassembling the sealing cover 3.
