Description

Technical Field

[0001] The utility model relates to the technical field of coaxial motors, in particular to a motor rotor with a noise reduction function. Background Art

[0002] Coaxial motor technology is a motor design method in which the rotor of the motor is aligned with the stator shaft so that the rotor and stator shaft share the same axis. This design can reduce the size of the motor, simplify the structure, improve efficiency, and reduce mechanical noise. Coaxial motors are commonly found in home appliances, automobiles, aerospace and other fields, such as the coaxial motor generator assembly of automobile engines. This technology plays an important role in reducing size, increasing power density and improving overall system efficiency.

The utility model prevents the resonance of the two motors when working by reducing the rotational inertia of the rotor, making the motor more stable when working.

[0004] The beneficial effects in the above patent specification mention that "by staggering the magnetic poles of the first rotor and the second rotor, the first rotor and the second rotor are subjected to more uniform force when subjected to the stator repulsion, thereby reducing the rotational inertia of the rotor, thereby preventing the two motors from resonating during operation and making the motors more stable during operation."

For this reason, a motor rotor with noise reduction function is proposed to solve the above problems. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Reference Figure 1 The utility model provides an embodiment: a motor rotor with a noise reduction function, comprising a base plate 1, the top of the base plate 1 is fixedly connected with a fixing assembly, the fixing assembly comprises two outer plates 2, the base plate 1 here plays a supporting and fixing role for the two outer plates 2, the bottom ends of the two outer plates 2 are fixedly connected to the top of the base plate 1, and the adjacent sides of the two outer plates 2 are fixedly connected with two rubber balls 3, and the outer plates 2 here play a supporting and fixing role for the rubber balls 3.

[0021] Reference Figure 1-Figure 2 , and at the same time provide it with a reaction force when it is hit. The top of the bottom plate 1 is fixedly connected to two inner plates 4, the inner wall of the fixed component is slidably connected to two outer columns 5, and the outer wall of the outer column 5 is fixedly connected to a rubber block 6. The rubber block 6 here will hit the surface of the rubber ball 3 when subjected to force. Because they are all made of rubber, they can offset the noise generated by the motor during operation to the maximum extent. The inner wall of the outer column 5 is covered with a spring 7.

[0022] Reference Figure 2-Figure 3 The inner wall of the outer column 5 is fixedly connected with a rubber block 2 8, and the spring 7 here can further offset the impact force. One end of the spring 7 is fixedly connected to one side of the rubber block 2 8, and the other end of the spring 7 is fixedly connected to one side of the rubber ring 9. The rubber block 2 8 and the rubber ring 9 here provide a stable support for the spring 7 to support its expansion and contraction. The inner wall of the fixed component is fixedly connected with two rubber rings 9, and the outer part of the outer column 5 is slidably connected to the inner wall of the rubber ring 9. The top of the bottom plate 1 is slidably connected with a shell 10, and the bottom plate 1 here plays a supporting and fixing role for the shell 10;

[0023] Reference Figure 2-Figure 3The top of the shell 10 is fixedly connected with a heat dissipation component, and the inner wall of the heat dissipation component is fixedly connected with a body 12. The heat dissipation component here can dissipate the heat generated by the motor during operation, thereby ensuring the high-performance rotation of the motor. The bottom end of the body 12 is slidably connected to the top of the bottom plate 1. The heat dissipation component includes two filters 11. The four sides of the two filters 11 are fixedly connected to the inner wall of the top of the shell 10. The shell 10 here plays a supporting and fixing role for the filter 11. The outer wall of the rubber block 6 is in contact with the inner wall of the rubber ball 3.

[0024] Working principle: When the machine body 12 here runs on the top of the bottom plate 1, the machine body 12 will vibrate left and right. When the machine body 12 vibrates, its left and right vibration force will be transmitted to the rubber block 2 8, and then the rubber block 2 8 will transmit the force to the outer column 5, which will prompt the outer column 5 to slide inside the inner plate 4 and drive the spring 7 to contract. At this time, part of the force will be reduced. As the outer column 5 continues to slide, the rubber block 1 6 will hit the rubber ball 3 on the inner wall of the outer plate 2.

[0025] At this time, because the rubber ball 3 and the rubber block 6 are made of rubber, the rubber block 6 will offset the remaining force when it hits the rubber ball 3 and minimize the noise emitted by the motor. Two filters 11 are fixedly connected to the shell 10 here, which can further enhance the heat dissipation capacity of the motor during rotation and enhance the operating performance.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
