Description

Technical Field

[0001] This invention relates to the field of synchronous motor technology, and more specifically to a clutch-type permanent magnet synchronous motor. Background Technology

[0002] Permanent magnet synchronous motors have advantages such as simple structure, small size, high efficiency, and high power factor, and are widely used in various industries. Permanent magnet excitation replaces excitation winding excitation, making the motor structure simpler, reducing processing and assembly costs, and eliminating the slip rings and brushes that are prone to problems, thus improving the reliability of motor operation. However, existing permanent magnet synchronous motors still have some disadvantages. Existing permanent magnet synchronous motors have the following two main shortcomings in use; When a permanent magnet synchronous motor is in use, it generates heat. In traditional motors, especially in humid areas, moisture and dust from the air can enter the motor during heat dissipation, causing corrosion of internal components and affecting the motor's lifespan. Motors generate vibrations of a certain amplitude during use, which produce noise and can affect the hearing of those around them. In addition, vibrations can cause wear on the motor surface, and prolonged vibrations can damage the casing, thus affecting the normal use of the motor. Summary of the Invention

[0024] Reference Figures 1-7 As shown, the present invention provides a clutch-type permanent magnet synchronous motor, including a motor body 1, a heat conduction component 2 is provided on one side of the motor body 1, a protective shell 3 is fixedly sleeved on the surface of the motor body 1 where the heat conduction component 2 is provided, a heat dissipation component 7 is fixedly connected inside the protective shell 3 and away from the inner wall of the motor body 1, a dustproof net 6 is provided on the inner side of the protective shell 3 away from the motor body 1, and support frames 4 are fixedly connected to both sides of the bottom of the motor body 1, and a shock-absorbing base 5 is movably connected to the bottom of the support frame 4.

[0025] In this embodiment, by providing a heat-conducting component 2, a dustproof net 6, and a one-way exhaust pipe 10, it is beneficial to exchange and transfer the heat inside the motor body 1 through the heat-conducting component 2, thereby avoiding direct contact between the inside of the motor body 1 and the outside. At the same time, the dustproof net 6 blocks dust in the outside air, and the one-way exhaust pipe 10 prevents outside air and impurities from entering, thereby preventing the motor body 1 from being affected by moisture and dust and enhancing its service life.

[0027] The heat-conducting component 2 includes a guide body 201, on the surface of which are regularly arranged temperature-conducting fins 202. The temperature-conducting fins 202 are fixedly sleeved inside the motor body 1 on the side away from the guide body 201. The guide body 201 has a conical structure.

[0028] The protective shell 3 has a protective inner cavity 302 inside, and an air inlet hole 301 is provided at the position where the dustproof net 6 is fixedly connected. The protective shell 3 has a neatly arranged one-way exhaust pipe 10 fixedly fitted around the surface of the protective shell 3.

[0029] The one-way exhaust pipe 10 includes a pipe body 1001, a pipe cavity 1002 is opened inside the pipe body 1001, a baffle 1003 is fixedly connected inside the pipe cavity 1002, and a one-way valve core 1004 is movably connected inside the pipe cavity 1002 and at the bottom of the baffle 1003. The baffle 1003 is semi-circular.

[0030] The heat dissipation component 7 includes a mounting bracket 701, a heat dissipation fan 702 is provided inside the mounting bracket 701, and a drive shaft 703 is fixedly connected to the center of the side of the heat dissipation fan 702 near the dustproof net 6.

[0031] A cleaning rod 704 is fixedly connected to the surface of the drive shaft 703 near the dustproof net 6, and a neatly arranged cleaning brush head 705 is provided on the surface of the cleaning rod 704 near the dustproof net 6.

[0032] Among them, the cleaning brush head 705 is made of soft boar bristles. The boar bristles are soft and elastic, can penetrate deep into the mesh for cleaning, and are not prone to generating static electricity.

[0033] Among them, the bottom two sides of the support frame 4 are fixedly connected with connecting rods 401, and the connecting rods 401 are movably sleeved inside the shock-absorbing base 5.

[0034] Among them, an airtight pipe 11 is fixedly connected inside the shock-absorbing base 5 and at the position of the connecting rod 401. An exhaust groove 501 is opened at the bottom of the shock-absorbing base 5 and at the position of the fixed airtight pipe 11. A circular through hole 1101 is opened on the surface of the airtight pipe 11 at the position of the exhaust groove 501. A spring 12 is movably sleeved inside the airtight pipe 11 and at the bottom position of the connecting rod 401. A rubber pad 13 is fixedly connected at the top of the shock-absorbing base 5 and at the position adjacent to the connecting rod 401.

[0035] The working principle of this invention is as follows: First, when the motor body 1 is running and generating heat, the heat dissipation component 7 inside the protective shell 3 is energized. At this time, the cooling fan 702 inside the fixing frame 701 rotates, and the rotation of the cooling fan 702 drives external air into the protective inner cavity 302. Then, the heat-conducting component 2 on one side of the motor body 1 exchanges the heat inside the motor body 1 to the temperature-conducting plate 202. Then, the air entering the protective inner cavity 302 passes through the dustproof net 6 to block dust, and the air force is dispersed to the surroundings through the air guide 201. At this time, the air force blows evenly on the surface of the temperature-conducting plate 202, and then cools the heat on the surface of the temperature-conducting plate 202. Then, the cooling of the temperature-conducting plate 202 causes the heat inside the motor body 1 to be exchanged again. The air heated by the heat-conducting plate 202 inside the protective inner cavity 302 reaches the airtight pipe 11 on the surface of the protective outer shell 3. Then, the one-way valve core 1004 is blown by the wind and flipped to the other side of the baffle 1003. At this time, the protective inner cavity 302 is connected to the outside through the pipe cavity 1002. Then, the heated air is discharged through the pipe cavity 1002. During this process, the water vapor in the air adheres to the surface of the heat-conducting plate 202 through the air guide 201 and the wind, thereby enhancing the overall cooling effect of the motor body 1. At the same time, the heat-conducting component 2 blocks the water vapor from entering the interior of the motor body 1. Meanwhile, the rotation of the cooling fan 702 drives the cleaning rod 704 and the cleaning brush head 705 to clean the surface of the dustproof net 6, thereby ensuring the ventilation of the dustproof net 6 and further enhancing the cooling effect of the motor body 1. Then, when the motor body 1 vibrates during operation, the smaller vibrations are absorbed by the flexibility of the rubber pad 13 itself, and the noise generated by the vibration is reduced under the support of the rubber pad 13. When the vibration of the motor body 1 is larger, the vibration of the motor body 1 is transmitted to the support frame 4, and then the connecting rod 401 is absorbed again by the spring 12 inside the airtight tube 11 and the air. When the spring 12 pushes the connecting rod 401 to reset, the circular through hole 1101 opened in the airtight tube 11 further restricts the air from entering, so that the connecting rod 401 cannot be quickly reset under the push of the spring 12, thereby reducing the vibration force generated by the operation of the motor body 1, thus completing the protection of the motor body 1 and preventing the motor body 1 from being damaged by vibration and affecting its normal use.

[0036] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
