Its primary function is to generate driving torque, serving as a power source for electrical appliances and various machines. A generator is represented in circuits by the letter G. Its primary function is to convert electrical energy into mechanical energy.

[0003] Existing motors generate a lot of noise when running, making the interior of the machine room noisy and causing ear discomfort to users when operating. The noise also causes sound pollution to the surrounding environment, affecting the normal life of residents and reducing people's work efficiency. Existing noise reduction methods usually place the motor in a cover to isolate the noise, but the noise reduction effect is not good; or by placing sound insulation boards around the motor to separate it from the external environment. The sound is reflected and absorbed on the sound insulation boards, thereby preventing the spread of noise. However, this method is not conducive to the heat dissipation of the motor and reduces the working efficiency of the motor to a certain extent. Utility Model Content

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0023] Reference Figures 1 to 4In a preferred embodiment, a motor with heat dissipation and noise reduction function includes a protective shell 10, a first end cover 11 is fixedly provided at one end of the protective shell 10, and a second end cover 12 is fixedly provided at the other end of the inner cavity of the protective shell 10, and ventilation holes are opened at equal intervals on the surface of the second end cover 12, and the ventilation holes are distributed in an arc shape; the opening of the ventilation holes will not cause the second end cover 12 to affect the heat flow in the protective shell 10 to the heat dissipation cover 20, the end of the protective shell 10 close to the second end cover 12 is sleeved with the heat dissipation cover 20, and a cooler 30 is fixed to the outside of the protective shell 10, A sound absorbing layer 13 is fixedly connected to the inner wall of the shell 10, an output shaft 14 is rotatably connected between the first end cover 11 and the second end cover 12, and a heat sink 21 is installed on the side of the second end cover 12 close to the heat dissipation cover 20. Preferably, the heat sink 21 can be made of copper or aluminum alloy, which is more conducive to dissipating the heat in the protective shell 10 from the heat dissipation port 22. In some embodiments, a heat conducting plate is fixed between the second end cover 12 and the heat sink 21, and the material of the heat conducting plate is silicone material; the heat conducting plate can more quickly concentrate the heat in the protective shell 10 to the position of the heat sink 21. The middle section of the output shaft 14 is connected to the rotor 15, and the end of the output shaft 14 located in the heat dissipation cover 20 is fixedly connected to the fan shell 31. Specifically, Figure 3 As shown, a drive motor 32 is installed on the fan housing 31, and a fan blade 33 is fixedly connected to the drive motor 32. A rubber frame 34 is bonded to the fan housing 31, and the rubber frame 34 is fixedly connected to the inner wall of the heat dissipation cover 20. A sound-absorbing sponge 35 is bonded to the inside of the fan housing 31, and a stator 16 is fixed to the inner wall of the protective shell 10 at the position corresponding to the rotor 15; a heat dissipation port 22 is provided at one end of the heat dissipation cover 20, and a placement groove is provided on the side walls around the heat dissipation port 22, and a noise reduction plate 41 is slidably connected in the placement groove, and an adjustment mechanism for adjusting the noise reduction plate 41 is provided at the upper end of the heat dissipation cover 20. During use, the driving motor 32 drives the fan blades 33 to rotate. During the rotation, the fan blades 33 generate suction to suck the hot air from the heat sink 21 out to the heat dissipation port 22. When the fan blades 33 rotate, the airflow is stirred to produce a sound of breaking wind, which can be absorbed by the sound-absorbing sponge 35. During the rotation of the fan blades 33, the fan housing 31 can be driven to vibrate. However, during the vibration of the fan housing 31, the rubber frame 34 can be squeezed to avoid noise caused by hard impact, thereby achieving the purpose of noise reduction.

[0024] like Figure 2As shown, in some embodiments, a plurality of noise reduction baffles 42 are staggered and arranged on the two opposite side walls of the heat dissipation cover 20 near the noise reduction plate 41. In some embodiments, through holes 401 are provided on the surface of the noise reduction plate 41 and the noise reduction baffle 42. The through holes 401 are distributed in a ring shape. A noise reduction layer 402 is fixed in the through holes 401. The opening of the through holes 401 allows the installation of the noise reduction layer 402. The material of the noise reduction layer 402 can be glass wool material. There are a large number of tiny gaps inside the glass wool material, which has a good absorption effect on noise; a heat dissipation hole is provided in the middle of the noise reduction layer 402. The opening of the heat dissipation hole is more conducive to dissipating the heat in the protective shell 10 out of the heat dissipation port 22. Furthermore, a plurality of noise reduction baffles 42 are staggered and arranged at intervals. Such an arrangement can form a staggered barrier path, which slows down the noise generated by the motor during operation so that it can circulate in the barrier path, thereby reducing the noise. At the same time, the staggered noise reduction baffles 42 can provide more air flow space between the heat sink 21 and the heat dissipation port 22, thereby facilitating better heat dissipation of the motor.

[0025] Specifically, the sound-absorbing layer 13 may be cylindrical in some embodiments. The sound-absorbing layer 13 includes sound-absorbing cotton 131, an interlayer 132 and an air gap 133. The interior of the protective shell 10 is fixedly connected with the sound-absorbing cotton 131. The sound-absorbing cotton 131 can absorb the noise generated when the motor is working, so that the sound of the motor rotation is reduced. It can be understood that in some other embodiments, the sound-absorbing cotton 131 can be set to be greater than one, and the distance between each two sound-absorbing cottons 131 is one centimeter. The gap between the sound-absorbing cottons 131 forms a vacuum state to further reduce noise. The interior of the sound-absorbing cotton 131 is fixedly connected with the interlayer 132, and the interior of the interlayer 132 is hollow. The interlayer 132 is The heat dissipation material, the interlayer 132 is used for noise reduction. The interlayer 132 with a hollow interior allows the noise generated by the motor during operation to circulate inside, thereby reducing the noise. The interlayer 132 can effectively transfer the heat generated by the motor to the inside. The interior of the interlayer 132 is fixedly connected with an air gap 133, and the interior of the air gap 133 is fixedly connected to the stator 16. The width of the air gap 133 is five millimeters. When the air gap 133 is increased, the amplitude of the harmonic magnetic field can be reduced, the unevenness of the air gap 133 can be reduced, and the amplitude of the radial force wave can be reduced, which can reduce the noise accordingly. Increasing the size of the air gap 133 reduces friction when the rotor 15 is in operation.

[0026] In some embodiments, a cooling pipe 50 is sleeved on the surface of the rotor 15. A water inlet pipe 60 is connected between the liquid inlet end of the cooling pipe 50 and the refrigerator 30, and a return pipe 70 is connected between the liquid outlet end of the cooling pipe 50 and the refrigerator 30. During the operation of this motor, to prevent excessive heat, the refrigerator 30 can be started. The refrigerator 30 transports coolant into the cooling pipe 50 through the water inlet pipe 60. The coolant in the cooling pipe 50 quickly cools the inside of the protective shell 10. The coolant in the cooling pipe 50 can then flow back to the refrigerator 30 through the return pipe 70. The motor electromagnetic circuit adopts a constant temperature design.

[0027] like Figure 4 As shown, in some embodiments, the adjustment mechanism includes a damping adjustment shaft 431, an adjustment block 432, a spring and a knob 434. The upper end of the heat dissipation cover 20 is rotatably connected to the damping adjustment shaft 431, and the damping adjustment shaft 431 extends into the placement groove. The end of the damping adjustment shaft 431 is fixedly connected to the adjustment block 432. The adjustment block 432 is located above the noise reduction plate 41. The lower end of the adjustment block 432 is provided with an inclined surface 435 that matches the noise reduction plate 41. A spring is elastically connected between the noise reduction plate 41 and the bottom of the placement groove. The upper end of the heat dissipation cover 20 is rotatably connected to the knob 434, and the knob 434 is fixedly connected to the damping adjustment shaft 431. When in use, the damping adjustment shaft 431 is rotated by the knob 434, and with the cooperation of the adjustment block 432 and the spring 433, the noise reduction plate 41 is placed in different vertical positions, thereby changing the relative position of the through hole 401 between the noise reduction plate 41 and the noise reduction baffle 42. The actual situation of internal and external air circulation can be changed according to the actual working conditions of the motor to ensure that the motor can dissipate heat better.
