[0002] The motor rotor assembly is one of the core components of the motor. It plays a very important role in converting electrical energy into mechanical energy. The magnetic field generated by the current in the rotor winding interacts with the stator magnetic field to generate a rotational torque, drive the rotor to rotate, and realize energy conversion.

[0003] After searching, the Chinese patent document announcement number: CN204967451U discloses a rotor assembly for a motor that can cool the heat generated by the rotor. The motor rotor assembly includes: a rotor core, which is a hollow cylindrical shape with a through hole formed in the center; a rotating shaft, which passes through the through hole and is combined with the rotor core; a first end ring, one side of which contacts one side of the rotor core; and a second end ring, which is spaced from the first end ring and arranged to be parallel to each other and one side contacts the other side of the rotor core, wherein the other side of the first end ring protrudes with a first guide pin, and the other side of the second end ring protrudes with a second guide pin, and the first guide pin and the second guide pin are wound into a spiral shape and protrude with the rotating shaft as the center. The motor rotor assembly of the utility model can reduce wind noise by reducing the air resistance of the rotor, and is easy to cool the rotor.

[0004] Regarding the above-mentioned related technologies, the inventor believes that the above patent mentioned in the specific implementation mode: "The rotor core is a hollow cylindrical shape with a through hole formed in the center; a rotating shaft, which passes through the through hole and is combined with the rotor core; a first end ring, one side of which contacts one side of the rotor core; and a second end ring, which is spaced apart from the first end ring and arranged to be parallel to each other and one side contacts the other side of the rotor core, wherein a first guide pin protrudes from the other side of the first end ring, and a second guide pin protrudes from the other side of the second end ring, and the first guide pin and the second guide pin are wound into a spiral shape with the rotating shaft as the center and protrude". Although the above patent is installed by multiple guide pins, it is impossible to avoid the device rotating during installation during the specific operation process, resulting in reduced installation efficiency. Therefore, in view of the above shortcomings, a motor rotor assembly is proposed. 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 - Figure 2 The utility model provides an embodiment: a motor rotor assembly, including a rotor shaft 1, a rotor column 2 is fixedly connected to the left end of the rotor shaft 1, and is used to provide support for the fixed block 3. The rotor column 2 is fixedly connected to the outside with multiple fixed blocks 3 for winding copper wires. The right end of the rotor shaft 1 is fixedly connected to the outside with a connecting tube 4, and is used to fix a connecting plate 5 separately. The connecting tube 4 is fixedly connected to the outside with multiple connecting plates 5, and is used to provide additional support for the magnetic pole plate 6. The far sides of the multiple connecting plates 5 are fixedly connected with the magnetic pole plate 6. The winding is performed simultaneously through the cooperation of the connecting plate 5, the pole plate 6 and the fixed block 3. The left side of the rotor shaft 1 is fixedly connected with a connecting sleeve 7 for connecting the rotating shaft 8, the limit plate 9 and the rotor shaft 1 for movement. The left side of the connecting sleeve 7 is fixedly connected with the rotating shaft 8. The outside of the connecting plate 5 is slidably connected with a rotor sleeve 10 for protecting and installing the internal structure. The upper and lower sides of the rotor sleeve 10 are provided with special-shaped openings 11 so that the limit plate 9 can have room for movement. Reset components are provided on the bottom sides of the left and right ends of the rotor sleeve 10.

[0021] Reference Figure 2 - Figure 4, the two reset assemblies each include two strong springs 12, the front and rear ends of the left portion of the rotor shaft 1 are respectively fixedly connected to the far side of the multiple strong springs 12, and the near side of the multiple strong springs 12 is fixedly connected to two arc plates 13. By fixing the two sides of the strong springs 12, the strong springs 12 can be uniformly stressed, the outer portions of the two arc plates 13 are respectively slidably connected to the inner walls of the front and rear ends of the left portion of the rotor shaft 1, and the outer portions of the two arc plates 13 are respectively slidably connected to the left ends of the two special-shaped openings 11. The arc plates 13 are restricted by the rotor shaft 1 and the special-shaped openings 11, so that the arc plates 13 can slide stably, the right sides of the two arc plates 13 are respectively slidably connected to the left sides of the two limit plates 9, and the limit plates 9 push the arc plates 13 to slide, the right side of the reset assembly is slidably connected to the limit plate 9, and the outer portions of the two limit plates 9 are respectively slidably connected to the inner walls of the front and rear ends of the rotor shaft 1, and two square openings 14 are provided at the front and rear ends of the left portion of the rotor shaft 1 for engaging the limit plates 9.

[0022] Working principle: We wrap the copper wire around the outside of the connecting plate 5 and block it with the pole plate 6, then bypass the fixed block 3 and put it into the inside of the rotor sleeve 10, and align the two limit plates 9 with the inside of the opened special-shaped opening 11 and slide it inside. After contacting the arc plate 13, the arc plate 13 will compress the strong spring 12, so that the strong spring 12 can store elastic potential energy, thereby giving the arc plate 13 a reverse force. At this time, by rotating the rotor shaft 1, both forward and reverse rotations are possible. After rotating to the point where it cannot rotate, release the pressure applied to the rotor shaft 1, and the strong spring 12 will push the arc plate 13 to slide inside the rotor sleeve 10, and further push the limit plate 9 to engage inside the opened square opening 14. At this time, the rotor shaft 1 cannot move, so it is convenient for subsequent installation.

[0023] 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.
