[0002] In many areas of modern industry and daily life, motors play an extremely critical role. They are widely used in machinery manufacturing, household appliances, transportation and other industries. With the continuous advancement of science and technology and people's increasing requirements for equipment performance, motors are facing higher challenges.

[0003] On the one hand, the motor will generate a lot of heat during operation. If the heat cannot be dissipated in time and effectively, the temperature rise of the motor will be too high, which will accelerate the aging of the motor insulation material, reduce its insulation performance, greatly shorten the service life of the motor, and even cause motor failure in severe cases, affecting the normal operation of the entire system;

[0004] On the other hand, the noise generated by the motor during operation has also become a problem that cannot be ignored. In some places with high requirements for environmental noise, such as hospitals, schools, office areas, and equipment rooms in residential areas, the motor noise will cause serious interference to the surrounding environment;

[0005] There are many deficiencies in the heat dissipation and sound insulation of traditional motors. In terms of heat dissipation, traditional motors often use natural heat dissipation, which is inefficient. In terms of sound insulation, traditional motors rely solely on casing sound insulation, which is difficult to meet high sound insulation standards and cannot adapt to the stringent requirements of motor heat dissipation and quietness in modern diversified scenarios. Therefore, it is of great practical significance to develop a motor that can quickly dissipate heat and effectively reduce noise. Summary of the invention

[0020] The present invention provides a silent motor capable of rapid heat dissipation, which has the following beneficial effects:

[0021] 1. This silent motor that can quickly dissipate heat has a heat dissipation resonance component, a heat sink and an arc-shaped spiral blade. When the motor is running, the heat sink increases the surface area of ​​the casing and dissipates heat to the surrounding environment. The arc-shaped spiral blade rotates with the drive shaft to stir the surrounding air and promote rapid heat transfer. The arc-shaped blades and their tooth-like protrusions in the heat dissipation resonance component further disturb the air, accelerate the air flow, and carry away the heat faster. The fan covers at both ends of the sleeve are in a trumpet shape and have spiral guide strips inside to guide the airflow to flow out smoothly, greatly improving the heat dissipation efficiency, effectively reducing the risk of motor failure due to overheating, and extending the service life of the motor.

[0022] Second, the silent motor that can quickly dissipate heat has components such as the sound insulation sponge of the first end shell component, the first ventilation plate and the second ventilation plate, and the wind shield of the second end shell component. When the noise generated by the motor is transmitted to the end shell, the sound insulation sponge absorbs part of the noise, the first ventilation plate and the second ventilation plate are separated and have different air holes to block the sound propagation, and the wind shield of the second end shell component is staggered to effectively reflect and block the noise from being transmitted. At the same time, the resonance member in the heat dissipation resonance component absorbs and converts the vibration energy through the vibration block and the spring, reducing the noise generated by the vibration, so that the noise is greatly reduced when the motor is running, meeting the use requirements of places with high requirements for environmental noise.

[0023] 3. The silent motor that can quickly dissipate heat has a docking assembly, and the first fixing block and the second fixing block are respectively located on the casing and the end casing. The annular clip strip and the annular clip groove are adapted to facilitate installation and disassembly of the first end casing assembly and the second end casing assembly with the casing. The annular sealing groove and the sealing strip prevent impurities from entering and provide sound insulation. The first mounting groove, the second mounting groove and the bolt reinforced connection ensure the stability of the overall structure of the motor, while facilitating maintenance personnel to inspect and replace parts inside the motor, thereby reducing maintenance costs and time.

[0024] 4. The silent motor that can quickly dissipate heat relies on components such as a docking assembly, a first bearing, and a second bearing. The docking assembly tightly connects the end shell to the casing to ensure the integrity and stability of the overall structure of the motor. The first bearing and the second bearing provide stable support for the transmission shaft, so that components such as the rotor assembly and arc-shaped spiral blades can rotate smoothly, reducing friction and shaking between components, improving the smoothness of the motor's operation, reducing failures caused by structural instability, and improving the reliability of the motor's operation.

[0025] 5. This silent motor that can quickly dissipate heat relies on the coordination of the spiral grooves of the rotor core and the spiral guide strips of the fan cover. When the rotor assembly rotates, the spiral grooves on the outer surface of the rotor core guide the air to flow along the grooves, and cooperate with the arc-shaped spiral blades and the heat dissipation resonance assembly to form an orderly airflow channel inside the motor. The spiral guide strips in the fan cover further standardize the airflow direction, improve the circulation efficiency of the air inside the motor, enhance the heat dissipation effect, and reduce the noise and energy loss caused by the turbulent airflow.

[0048] The second embodiment is based on the first embodiment. Figures 1 to 10 As shown, the transmission shaft 2 is arranged in the middle of the housing 1, and the transmission shaft 2 is fixedly connected to the inner side of the first bearing 10 and the second bearing 11. The outer surface of the transmission shaft 2 is sequentially installed with arc-shaped spiral blades 5, a rotor assembly 6 and a heat dissipation resonance assembly 7. The arc-shaped spiral blades 5 and the rotor assembly 6 are fixedly installed on the outer surface of the transmission shaft 2. The number of the arc-shaped spiral blades 5 is two. When the current passes through the stator assembly 8 to generate a magnetic field, the rotor assembly 6 rotates under the action of the magnetic field, driving the transmission shaft 2 to rotate. The heat dissipation resonance assembly 7 is used to enhance heat dissipation and reduce noise.

[0049] The heat dissipation resonance component 7 includes a sleeve 71 and a fan cover 72. The sleeve 71 is fixedly mounted on the outer surface of the transmission shaft 2. An arc-shaped blade 76 is fixedly mounted on the outer surface of the sleeve 71. A tooth-shaped protrusion is arranged at the edge of the arc-shaped blade 76.

The current generates a magnetic field through the stator assembly 8. The stator assembly 8 is fixed to the inner wall of the casing 1 and is located outside the rotor assembly 6. At this time, the rotor assembly 6 starts to rotate under the action of the magnetic field, driving the transmission shaft 2 fixedly connected thereto to rotate. The transmission shaft 2 is stably supported and rotated by the first bearing 10 and the second bearing 11. The spiral grooves 62 on the outer surface of the rotor core 61 guide the air flow to accelerate the heat dissipation. At the same time, the arc-shaped spiral blades 5 on the transmission shaft 2 also rotate with the transmission shaft 2, disturbing the surrounding air to help heat dissipation.

[0053] The first ventilation plate 34 and the second ventilation plate 35 allow outside air to enter the motor, and the sound insulation sponge 36 in the middle absorbs and blocks the noise generated by the operation of the motor. At the same time, the wind shield 44 in the ventilation hole 42 of the second end shell assembly 4 blocks the sound transmission;
