Description

Technical Field

[0001] This utility model relates to the field of reluctance motor technology, and in particular to a reluctance energy storage motor with a noise reduction mechanism. Background Technology

[0002] A magnetic reluctance energy storage motor is a type of motor that uses the magnetic reluctance effect to store and release energy. This type of motor usually combines the functions of an energy storage device and a motor, and can store energy without using traditional batteries or other energy storage media. It plays an important role in fields such as flywheel energy storage systems. During operation, due to its structural characteristics, it is prone to generating large vibrations and noise. In order to reduce these adverse factors, a noise reduction mechanism is usually installed on the outside of the motor to reduce noise.

[0003] A search revealed Chinese Patent Publication No. CN212969274U, which discloses a noise-reducing switched reluctance motor. This motor features a noise-reducing and heat-dissipating housing mechanism that facilitates better motor operation, providing heat dissipation, noise reduction, insulation, and waterproofing, thus increasing the motor's lifespan. During use, the housing provides overall support and protection. The sound-absorbing pad is made of sound-absorbing cotton, offering excellent noise reduction and ease of use. The heat sink is made of graphene, providing superior heat dissipation performance.

[0004] In actual use, when the aforementioned reluctance motor is covered with a sound-absorbing pad to reduce noise, the porous structure and fiber arrangement of the sound-absorbing cotton cause heat to undergo more friction and vibration as it passes through, thus reducing heat transfer efficiency and consequently reducing the motor's heat dissipation effect and affecting its service life. Therefore, a reluctance energy storage motor with a noise reduction mechanism is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a reluctance energy storage motor with a noise reduction mechanism, which aims to improve the problem that the heat dissipation effect of the motor is affected when the sound-absorbing cotton is directly wrapped around the outside of the reluctance motor for noise reduction in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a magnetic reluctance energy storage motor with a noise reduction mechanism, comprising a motor body, a rotating shaft at the front end of the motor body, an inner heat-conducting cylinder fixedly connected to the outer side of the motor body, a heat-conducting strip fixedly connected to the outer side of the inner heat-conducting cylinder, an outer heat-conducting cylinder fixedly connected to the outer side of the heat-conducting strip, a sound-absorbing cotton strip fixedly connected to the outer surface of the inner heat-conducting cylinder, and a heat dissipation fin fixedly connected to the outer side of the outer heat-conducting cylinder.

[0007] As a further description of the above technical solution:

[0008] An installation cylinder is sleeved on the left side of the outer heat-conducting cylinder, and a filter strip is fixedly connected to the right end of the installation cylinder. Bolts are provided on both the front and rear sides of the installation cylinder.

[0011] As a further description of the above technical solution:

[0012] The sound-absorbing cotton strip has an S-shaped groove inside, which runs through the sound-absorbing cotton strip.

[0013] As a further description of the above technical solution:

[0014] The number of heat-conducting strips is several, and the several heat-conducting strips are arranged in a ring array on the outside of the inner heat-conducting cylinder.

[0015] As a further description of the above technical solution:

[0016] The number and position of the heat dissipation fins fixedly connected to the outside of the outer heat-conducting cylinder are adapted to the position and number of the heat-conducting strips.

[0017] As a further description of the above technical solution:

[0018] The outer heat-conducting cylinder is sleeved on the outside of the inner heat-conducting cylinder.

[0019] As a further description of the above technical solution:

[0020] The inner wall of the filter strip is in contact with the outer wall of the outer heat-conducting cylinder.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by combining the inner heat-conducting cylinder, heat-conducting strip, outer heat-conducting cylinder, sound-absorbing cotton strip, heat dissipation fins, heat dissipation holes and S-shaped through grooves, it is possible to absorb and reduce the noise generated by the reluctance motor while quickly transferring the heat generated by the motor during operation to the outside, thereby achieving rapid heat dissipation and avoiding the situation where covering the outside of the reluctance motor with sound-absorbing cotton for noise reduction would reduce the heat dissipation effect of the reluctance motor.

[0023] 2. In this utility model, the air entering the heat dissipation hole can be filtered by the combination of the installation cylinder, filter strip and bolt, so as to prevent dust and impurities from entering the heat dissipation hole and S-shaped groove and affecting the noise reduction effect of the sound-absorbing cotton strip. At the same time, the installation cylinder and filter strip can be quickly disassembled for easy cleaning and simple operation. Attached Figure Description

[0031] 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.

[0032] Reference Figures 1-2 The present invention provides an embodiment of a reluctance energy storage motor with a noise reduction mechanism, comprising a motor body 1, a rotating shaft 2 at the front end of the motor body 1, and an inner heat-conducting cylinder 3 fixedly connected to the outer side of the motor body 1. The heat generated by the reluctance motor during operation can be transferred to the inner heat-conducting cylinder 3 through its outer shell. A number of heat-conducting strips 4 are fixedly connected to the outer side of the inner heat-conducting cylinder 3. The heat-conducting strips 4 are arranged in a ring array on the outer side of the inner heat-conducting cylinder 3. The heat transferred to the inner heat-conducting cylinder 3 can be further transferred and dissipated to the outside through the heat-conducting strips 4.

[0033] Reference Figures 2-4An outer heat-conducting cylinder 5 is fixedly connected to the outside of the heat-conducting strip 4. The heat transferred to the inner heat-conducting cylinder 3 will be transferred to the outer heat-conducting cylinder 5 through the heat-conducting strip 4, and finally transferred to the outside through the outer heat-conducting cylinder 5 for rapid heat dissipation. The outer heat-conducting cylinder 5 is sleeved on the outside of the inner heat-conducting cylinder 3. A sound-absorbing cotton strip 6 is fixedly connected to the outer surface of the inner heat-conducting cylinder 3. An S-shaped through groove 9 is opened inside the sound-absorbing cotton strip 6. The S-shaped through groove 9 passes through the sound-absorbing cotton strip 6.

[0034] By setting the S-shaped structure of the S-shaped through groove 9, noise can be prevented from being directly transmitted through the through groove. At the same time, the heat on the surface of the inner heat-conducting cylinder 3 can be dissipated to the outside through the S-shaped through groove 9, so that the heat of the inner heat-conducting cylinder 3 can be further dissipated quickly, reducing the impact on the effect of the sound-absorbing cotton strip 6. The sound-absorbing cotton strip 6 fills the space formed between the inner heat-conducting cylinder 3, the heat-conducting strip 4 and the outer heat-conducting cylinder 5. The sound-absorbing cotton strip 6 can absorb the sound waves generated by the motor body 1 during operation, reduce noise and echo, and improve the external acoustic environment when the reluctance motor is working.

[0035] Heat dissipation fins 7 are fixedly connected to the outer side of the outer heat conduction cylinder 5. The number and position of the heat dissipation fins 7 fixedly connected to the outer side of the outer heat conduction cylinder 5 are adapted to the position and number of heat conduction strips 4. The heat dissipation fins 7 can increase the heat dissipation surface area of ​​the outer heat conduction cylinder 5 to effectively dissipate heat. At the same time, the heat transferred to the outer heat conduction cylinder 5 through the heat conduction strips 4 can be quickly transferred to the heat dissipation fins 7, further improving the heat dissipation efficiency. Heat dissipation holes 8 are opened on the outer surface of the outer heat conduction cylinder 5. The heat dissipation holes 8 can increase the heat dissipation area of ​​the outer heat conduction cylinder 5, further improving the heat dissipation effect. At the same time, the heat generated when the sound-absorbing cotton strips 6 absorb noise can also be directly discharged through the heat dissipation holes 8, which can improve the noise absorption efficiency of the sound-absorbing cotton strips 6.

[0036] Reference Figure 1 and Figure 5 An installation cylinder 10 is sleeved on the left side of the outer heat-conducting cylinder 5, and a filter strip 11 is fixedly connected to the right side of the installation cylinder 10. The inner wall of the filter strip 11 fits against the outer wall of the outer heat-conducting cylinder 5. The filter strip 11 can filter the inside of the heat dissipation hole 8 to prevent dust and impurities from entering the heat dissipation hole 8 and the S-shaped groove 9, which would affect the performance of the sound-absorbing cotton strip 6. Bolts 12 are provided on both the front and rear sides of the installation cylinder 10. The installation cylinder 10 is fixedly connected to the outside of the outer heat-conducting cylinder 5 by the bolts 12. When it is necessary to disassemble and clean the installation cylinder 10 and the filter strip 11, the fixing of the installation cylinder 10 can be released by simply unscrewing the bolts 12. The operation is simple.

[0037] Working principle: The sound-absorbing cotton strip 6 set on the outside of the motor body 1 can absorb and reduce the noise generated by the reluctance motor during operation, thereby reducing noise. The heat generated by the reluctance motor during operation can be quickly transferred to the outer heat-conducting cylinder 5 through the inner heat-conducting cylinder 3 and the heat-conducting strip 4, and then transferred to the outside through the outer heat-conducting cylinder 5 and the heat dissipation fins 7, thereby achieving rapid heat dissipation. At the same time, the heat in the sound-absorbing cotton strip 6 and the inner heat-conducting cylinder 3 can also be quickly dissipated to the outside air through the heat dissipation holes 8 and the S-shaped groove 9, improving the heat dissipation efficiency and the effect of the sound-absorbing cotton strip 6. During use, the filter strip 11 will filter the air entering the heat dissipation hole 8, preventing dust and impurities from entering the heat dissipation hole 8 and the S-shaped groove 9. When a large amount of dust and impurities adhere to the surface of the filter strip 11 and cleaning is required, simply unscrew the bolt 12 to release the limit on the mounting cylinder 10, and then the mounting cylinder 10 and the filter strip 11 can be directly removed for cleaning, which is simple to operate.

[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.
