[0002] With the development of modern technology, many devices are moving towards miniaturization and micro-miniaturization, such as small robots, drones, handheld electronic devices, and wearable devices.
[0003] The adjustable miniature geared motor consists of a motor body, a gearbox, and an adjustment device. When the motor is energized, power is transmitted via the shaft to the gearbox, where multiple gear sets reduce speed. During adjustment, the speed controller changes the PWM duty cycle to adjust the speed, and the torque adjustment mechanism changes the transmission method or adjusts the torque through friction. Ultimately, the power is delivered to the output shaft to drive the equipment.
[0004] In existing technologies, the reliability of some motors is significantly reduced due to the lack of sealing, as components are easily damaged by factors such as dust, moisture, and corrosion. This increases the frequency of motor failures, affects the normal operation of the equipment, leads to equipment downtime for maintenance, and increases maintenance and time costs. Therefore, an adjustable micro geared motor is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an adjustable micro geared motor, which aims to improve the problems in the prior art where the motor is not sealed, and the components are easily damaged by dust, moisture and corrosion, resulting in increased failure frequency, affected equipment operation, increased downtime for maintenance and increased maintenance and time costs.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An adjustable miniature geared motor includes a base plate, a protective shell fixedly connected to the top of the base plate, a motor fixedly connected inside the protective shell, a connecting cover slidably connected to the front side of the motor, a plurality of sliding columns slidably connected inside the connecting cover, a spring fixedly connected inside each of the connecting cover, a triangular block fixedly connected to the adjacent side of each sliding column, a baffle fixedly connected to the distant side of each sliding column, a sealing ring fixedly connected to the right side of the connecting cover, and a noise reduction component for buffering fixedly connected to the top of the base plate.
[0008] As a further description of the above technical solution:

A sliding ring is slidably connected to the outside of each fixing column. A spring is fixedly connected to an adjacent side of each sliding ring, and a connecting rod is rotatably connected to an adjacent side of each sliding ring.
[0010] As a further description of the above technical solution:
[0011] The proximal side of one of the multiple baffles contacts the distal side of the connecting cover, and the interior of the connecting cover is provided with multiple slots.
[0012] As a further description of the above technical solution:
[0013] The external parts of the plurality of triangular blocks are slidably connected to the inside of the protective shell, and the external parts of the plurality of sliding columns are sleeved inside the plurality of springs.

[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, the protective shell is fixed on the base plate and protects the internal motor. The sliding column can slide under the action of the spring. The sliding of the sliding column causes the triangular block to have an interlocking or positioning effect inside the protective shell. The sealing ring on the connecting cover ensures the internal sealing of the motor, ensuring stable operation of the motor and extending its service life. The seal can isolate the inside of the motor from the external environment, preventing dust and debris from entering. The seal can also prevent moisture from entering the inside of the motor, thereby extending the service life of these components.
[0024] 2. In this utility model, the internal baffle two can slide inside and cooperate with the support column. When the motor vibrates, the support column buffers the vibration under the elastic deformation of the spring two. The connecting plate and the connecting rod reduce the noise generated by the vibration. The sliding ring on the fixed column slides under the elastic force of the spring three, thereby reducing the noise of the motor. Long-term exposure to high noise environment will damage people's hearing. This is especially true for workers who operate adjustable micro geared motor equipment for a long time.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0033] Reference Figures 1 to 3 This utility model provides an embodiment of an adjustable micro geared motor, including a base plate 1. A protective shell 2 is fixedly connected to the top of the base plate 1. The base plate 1 is the basic support component of the entire motor 10 structure. The motor 10 is fixedly connected inside the protective shell 2, which wraps around the motor 10 and plays a major protective role. A connecting cover 3 is slidably connected to the front side of the motor 10. The connecting cover 3 is an important component on the front side of the motor 10, playing a connecting and protective role. Multiple sliding posts 4 are slidably connected inside the connecting cover 3. The sliding posts 4 slide inside the connecting cover 3 and are a key part of the sealing and connection structure. Springs 6 are fixedly connected inside the connecting cover 3. The springs 6 are installed inside the connecting cover 3. Triangular blocks 7 are fixedly connected to the outer side of the sliding column 4 and the adjacent side of the sliding column 4. The triangular blocks 7 can slide inside the protective shell 2 under the drive of the sliding column 4. Utilizing their triangular shape, some mechanical interlocking or positioning effects may be generated during the sliding process. Baffles 5 are fixedly connected to the opposite side of the sliding column 4. The adjacent side of the baffles 5 is in contact with the opposite side of the connecting cover 3. A sealing ring 9 is fixedly connected to the right side of the connecting cover 3. The small gap between the connecting cover 3 and the protective shell 2 forms a sealing barrier to prevent leakage or seepage, ensure the sealing of the internal environment of the motor 10, and extend the service life of the motor 10. A noise reduction component for buffering is fixedly connected to the top of the base plate 1.
[0034] Reference Figure 4 , Figure 5The noise reduction component includes two parts 11. Part 11 is the basic structure of the noise reduction component. Two baffles 12 are slidably connected inside each part 11. When subjected to external vibration or vibration generated by the motor 10 itself, the baffles 12 can move within part 11, cooperating with other parts to buffer and block the propagation of vibration. Support columns 13 are fixedly connected to adjacent sides of each baffle 12. The support columns 13 are fixed to the adjacent side of each baffle 12, and their exteriors are fitted inside springs 15. Springs 15 are fixedly connected to adjacent sides of each part 11. When the motor 10 vibrates during operation, springs 15 will undergo elastic deformation. Connecting plates 14 are fixedly connected to adjacent sides of each support column 13. Connecting plates 14 connect the support columns 13, and their opposite sides are rotatably connected to connecting rods 17. One side is in contact with the outside of the protective shell 2. A fixed column 16 is fixedly connected inside the 11. The fixed column 16 ensures that the sliding ring 18 can slide stably on a certain track, providing positioning and support for the subsequent linkage of the connecting rod 17 and the spring 19. The sliding ring 18 is slidably connected to the outside of the fixed column 16. The sliding ring 18 can slide on the fixed column 16, driving the connecting rod 17 to move. Through the coordinated work with the spring 19, the adjacent sides of the sliding ring 18 are fixedly connected to the spring 19. The spring 19 provides elastic force, so that the sliding ring 18 can perform elastic movement when subjected to the force of the connecting rod 17. The adjacent sides of the sliding ring 18 are rotatably connected to the connecting rod 17. The connecting rod 17 can transmit the movement of the sliding ring 18 to the connecting plate 14, linking the different parts of the components together to effectively reduce shock.
[0035] Reference Figures 3 to 5Multiple baffles 5 are in contact with the opposite side of the connecting cover 3. Multiple slots 8 are provided inside the connecting cover 3. The connecting cover 3 is slidably connected to the motor 10, which helps to enclose part of the motor 10's structure and provides a mounting base for subsequent sealing and noise reduction components. Multiple triangular blocks 7 are externally slidably connected inside the protective shell 2. The triangular blocks 7 ensure a more secure and stable connection between the connecting cover 3 and the protective shell 2, and also provide auxiliary sealing. Multiple sliding pillars 4 are externally fitted inside multiple springs 6. The extension and retraction of the springs 6 can adjust the position of the sliding pillars 4, ensuring structural flexibility and adaptability to different working conditions, and helping to maintain tight contact between the connecting cover 3 and other components. The right side of the sealing ring 9 is in contact with the left side of the protective shell 2. Multiple support pillars 13 are externally fitted inside multiple springs 15. The support pillars 13 ensure the stable movement of the baffle 12. Through the elastic action of the springs 15, the baffle 12 can elastically adjust its position when subjected to vibration. To absorb and disperse vibration energy and reduce vibration amplitude, the two connecting plates 14 are rotatably connected to the adjacent side of the connecting rod 17 on opposite sides. The connecting rod 17 can transmit the movement of the sliding ring 18 to the connecting plate 14, linking different parts together. The outer sides of the two fixed columns 16 are fitted inside the two springs 19. Two slots 20 are opened on the temporal part of the two 11. The slots 20 are opened inside the component 11 and provide limiting and positioning functions for the movement of certain components. The adjacent side of the two connecting plates 14 is in contact with the outer side of the protective shell 2. The bottom of the two connecting plates 14 is slidably connected to the top of the base plate 1. At the same time, a part of the vibration is transmitted to the entire motor 10 structure through contact with the protective shell 2. The elasticity and buffering of the structure are used to reduce noise. The opposite side of the two connecting plates 14 is in contact with the adjacent side of multiple springs 15. When the motor 10 vibrates during operation, the springs 15 will undergo elastic deformation, buffering the vibration energy through extension and contraction, and reducing the intensity of vibration transmitted to the external structure of the motor 10.
[0036] Working principle: The protective shell 2 is fixed on the base plate and protects the internal motor 10. There is a sliding column 4 in the connecting cover 3 on the front side of the motor 10. The sliding column 4 can slide under the action of spring 6. The triangular block 7 on the near side and the baffle 5 on the far side move accordingly. The sliding of the sliding column 4 makes the triangular block 7 interlock or position within the protective shell 2. The sealing ring 9 on the connecting cover 3 ensures the internal sealing of the motor, ensuring the stable operation of the motor 10 and extending its service life. The seal can isolate the inside of the motor 10 from the external environment, preventing dust and debris from entering and preventing them from entering key parts such as the windings, iron core and bearings of the motor 10, thereby extending the service life of these components. The seal can also prevent moisture from entering the inside of the motor 10.
[0037] As a basic structure, component 11 has an internal baffle 12 that can slide inside and cooperate with the support column 13. When the motor 10 vibrates, the baffle 12 moves, and the support column 13 buffers the vibration under the elastic deformation of the spring 15. The connecting plate 14 connects to the support column 13 and is rotatably connected to the connecting rod 17. The sliding ring 18 on the fixed column 16 slides under the elastic force of the spring 19, driving the connecting rod 17 to move, thereby reducing the noise of the motor 10. Long-term exposure to high noise environments can damage a person's hearing. For workers who operate the adjustable micro geared motor 10 for a long time, such as factory workers, the noise reduction of the motor 10 can reduce the noise intensity and protect their hearing health.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
