Description

A self-cleaning servo motor for ventilation openings Technical Field

[0001] This utility model belongs to the field of motor technology, specifically relating to a self-cleaning servo motor for ventilation openings. Background Technology

[0002] A servo motor is an engine used in servo systems to control the operation of mechanical components. Servo motors enable highly accurate control of speed and position, converting voltage signals into torque and speed to drive the controlled object. The rotor speed of a servo motor is controlled by the input signal and can respond quickly. In automatic control systems, it is used as an actuator and possesses characteristics such as a small electromechanical time constant, high linearity, and low starting voltage. It can convert received electrical signals into angular displacement or angular velocity output on the motor shaft. Servo motors are broadly classified into DC and AC servo motors. Their main characteristic is that they do not rotate when the signal voltage is zero, and their speed decreases uniformly as the torque increases.

[0003] The motor fan cover is an indispensable part of the motor, playing a crucial role in ventilation and heat dissipation during operation. The quality of ventilation directly affects the motor's operating condition. Currently, motor fan covers are relatively simple in design, making it easy for debris such as catkins, insects, and leaves to accumulate at the air inlet during motor operation. In winter, frost can also easily form at the air inlet. Prolonged operation can cause blockage of the fan inlet, reducing the airflow to the motor. Reduced airflow can lead to motor overheating, and in severe cases, motor burnout. Summary of the Invention

[0004] The purpose of this utility model is to provide a self-cleaning servo motor for air inlets. Through the cooperation of the main body, cover, fixed seat, rotating sleeve, transmission gear, brush plate, contact seat, first rack, connecting seat, second rack and pull ring, the pull ring is used to drive the contact seat to move towards the center platform. Then, the friction between the contact seat and the center platform drives the brush plate to rotate through the rotating sleeve, thus completing the self-cleaning of the air inlet of the cover. It is convenient to use.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A self-cleaning servo motor for ventilation openings includes:

[0007] The main body includes a rotating shaft, and a fan is mounted on one end of the rotating shaft on the outside of the main body. The fan includes a central platform and fan blades.

[0008] The cover is installed on the main body and forms a cover over the end of the main body where a fan is installed. The inner wall of the cover has several air inlets evenly distributed at the end away from the main body. A gap is left between the inner wall of the cover and the outer wall of the main body.

[0009] The fixing seat is fixedly installed on the cover;

[0010] A rotating sleeve is rotatably mounted in a fixed base. The central axis of the rotating sleeve coincides with the central axis of the rotating shaft. The rotating sleeve has a hollow structure, and a transmission gear is rotatably mounted inside the rotating sleeve.

[0011] A brush plate is fixedly mounted on a rotating sleeve and located on the outside of the cover. The brush plate has bristles on the side near the air inlet.

[0012] The rotating sleeve has a first rack and a second rack slidably installed inside. The first rack and the second rack are located on both sides of the transmission gear and are both meshed with the transmission gear. The length direction of the first rack and the second rack is parallel to the central axis of the rotating shaft.

[0013] The first rack is fixedly provided with a contact seat at one end near the center platform;

[0014] A connecting seat is fixedly provided at the end of the second rack away from the center platform, and a pull ring is rotatably installed at the end of the connecting seat away from the second rack.

[0015] Furthermore, the contact seat is equipped with a magnet for attracting the second rack.

[0016] This structural design, through the attraction of the second rack with a magnet, temporarily fixes the contact seat before the pull ring is pulled, preventing the contact seat from accidentally contacting the center platform due to motor vibration, making it highly practical.

[0017] Furthermore, a compression spring is installed on the end of the rotating sleeve away from the second rack at the connecting seat;

[0018] A limit ring is installed inside the rotating sleeve;

[0019] The free end of the compression spring rests against the end of the limiting ring near the connecting seat.

[0020] This structural design, through the compression spring pushing the connecting seat, temporarily fixes the contact seat before the pull ring is pulled, preventing the contact seat from accidentally contacting the center platform due to motor vibration, making it highly practical.

[0021] Further specifying, the pull ring includes a connecting rod, and the compression spring is sleeved on the connecting rod;

[0022] The connecting rod is rotatably connected to the connecting seat.

[0023] This structural design uses a connecting rod to achieve a rotating connection between the pull ring and the connecting seat. It is simple in structure, easy to install, and highly practical.

[0024] Furthermore, a bearing is installed between the connecting rod and the connecting seat.

[0025] This structural design, which uses bearings to complete the rotational installation between the connecting rod and the connecting seat, reduces the friction between the connecting rod and the connecting seat, making the rotation of the connecting seat smoother and more practical.

[0026] Furthermore, the transmission gears are two in number, and the plane containing the central axes of the two transmission gears coincides with the central axis of the rotating shaft.

[0027] This structural design, where two transmission gears mesh simultaneously with the first and second racks, reduces the pressure on the transmission gears and is highly practical.

[0028] The utility model adopting the above technical solution has the following advantages:

[0029] Through the cooperation of the main body, cover, fixed seat, rotating sleeve, transmission gear, brush plate, contact seat, first rack, connecting seat, second rack and pull ring, the pull ring is used to drive the contact seat to move towards the center platform. Then, the friction between the contact seat and the center platform drives the brush plate to rotate through the rotating sleeve, thus completing the self-cleaning of the air inlet of the cover. It is easy to use. Attached Figure Description

[0045] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. Furthermore, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0046] As shown in Figures 1 to 5, the present invention provides a self-cleaning servo motor for ventilation openings, comprising:

[0047] The main body 1 includes a rotating shaft 11, and a fan is mounted on one end of the rotating shaft 11 on the outside of the main body 1. The fan includes a central platform 12 and fan blades 120.

[0048] Cover 2 is installed on the main body 1 and forms a cover over the end of the main body 1 where a fan is installed. Several air inlets 21 are evenly opened on the inner wall of the cover 2 away from the main body 1. A gap is left between the inner wall of the cover 2 and the outer wall of the main body 1.

[0049] Fixing seat 3 is fixedly installed on cover 2;

[0050] Rotating sleeve 4 is rotatably installed in fixed base 3. The central axis of rotating sleeve 4 coincides with the central axis of rotating shaft 11. Rotating sleeve 4 has a hollow structure and a transmission gear 40 is rotatably installed inside rotating sleeve 4.

[0051] Brush plate 5 is fixedly installed on rotating sleeve 4 and located on the outside of cover 2. Brush plate 5 has bristles 50 on the side near air inlet 21.

[0052] A first rack 61 and a second rack 71 are slidably installed inside the rotating sleeve 4. The first rack 61 and the second rack 71 are located on both sides of the transmission gear 40 and are both meshed with the transmission gear 40. The length direction of the first rack 61 and the second rack 71 is parallel to the central axis of the rotating shaft 11.

[0053] A contact seat 6 is fixedly provided at one end of the first rack 61 near the center platform 12;

[0054] A connecting seat 7 is fixedly provided at the end of the second rack 71 away from the center platform 12, and a pull ring 8 is rotatably installed at the end of the connecting seat 7 away from the second rack 71.

[0055] A magnet for attracting the second rack 71 is installed on the contact seat 6.

[0056] By using a magnet to attract the second rack 71, the contact seat 6 is temporarily fixed before the pull ring 8 is pulled, thus preventing the contact seat 6 from accidentally contacting the center platform 12 due to motor vibration. This method is highly practical.

[0057] A compression spring 42 is installed on the end of the rotating sleeve 4 away from the second rack 71 of the connecting seat 7;

[0058] A limit ring 41 is installed inside the rotating sleeve 4;

[0059] The free end of the compression spring 42 rests against the end of the limiting ring 41 near the connecting seat 7.

[0060] By pushing the connecting seat 7 with the compression spring 42, the contact seat 6 is temporarily fixed before the pull ring 8 is pulled, so as to avoid the contact seat 6 accidentally contacting the center platform 12 due to motor vibration, which is highly practical.

[0061] The pull ring 8 includes a connecting rod 80, and a compression spring 42 is sleeved on the connecting rod 80;

[0062] The connecting rod 80 is rotatably connected to the connecting seat 7.

[0063] In practice, depending on the actual situation, an annular boss located inside the compression spring 42 can be provided on the connecting seat 7. The annular boss is rotated to connect with the pull ring 8, thus completing the rotational connection between the pull ring 8 and the connecting seat 7. In this embodiment, the rotational connection between the pull ring 8 and the connecting seat 7 is completed through the connecting rod 80. The structure is simple, easy to install, and highly practical.

[0064] A bearing 70 is installed between the connecting rod 80 and the connecting seat 7.

[0065] In practice, depending on the actual situation, a through hole can be directly made on the connecting seat 7 so that the connecting rod 80 passes through the connecting seat 7 and is then axially limited to achieve the rotational installation between the connecting rod 80 and the connecting seat 7. In this embodiment, the rotational installation between the connecting rod 80 and the connecting seat 7 is completed by the bearing 70, which can reduce the friction between the connecting rod 80 and the connecting seat 7, making the rotation of the connecting seat 7 smoother and more practical.

[0066] There are two transmission gears 40, and the plane containing the central axis of the two transmission gears 40 coincides with the central axis of the rotating shaft 11.

[0067] In practice, depending on the actual situation, only one transmission gear 40 can be set, or three or four transmission gears 40 can be set. In this embodiment, by having two transmission gears 40 mesh with the first rack 61 and the second rack 71 at the same time, the pressure on the transmission gears 40 can be reduced, which is more practical.

[0068] In this embodiment, during the use of the motor, the rotating shaft 11 drives the fan to rotate to dissipate heat from the main body 1. At this time, the contact seat 6 is not in contact with the center platform 12 (as shown in Figures 1-3).

[0069] When it is necessary to clean the air inlet 21 of the motor housing 2, grasp the pull ring 8 and pull it away from the main body 1. The second rack 71 will move away from the main body 1 in sequence through the connecting rod 80, bearing 70 and connecting seat 7. By using the method that the second rack 71 and the first rack 61 are both engaged with the transmission gear 40, the first rack 61 will move closer to the main body 1, which will in turn move the contact seat 6 closer to the center platform 12 until the contact seat 6 abuts against the center platform 12 (as shown in Figures 4 and 5).

[0070] At this time, the contact seat 6 rotates under the drive of the central platform 12, which in turn drives the rotating sleeve 4 and the brush plate 5 to rotate via the first rack 61, thereby cleaning the dust in the air inlet 21 of the cover 2.

[0071] The above provides a detailed description of a self-cleaning servo motor for ventilation openings provided by this utility model. The specific embodiments are described only to aid in understanding the method and core concept of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
