[0002] Magnetic plastics are a new type of polymer functional material developed in the 1970s and are one of the important basic materials in the field of modern science and technology. Magnetic plastics can be divided into two types based on their composition: structural and composite. Structural magnetic plastics refer to magnets whose polymers themselves possess strong magnetism; composite magnetic plastics refer to magnets made by mixing plastic or rubber as an adhesive with magnetic powder. However, existing plastic magnetic rotor manufacturing has shortcomings, such as:

[0003] Publication No. CN220254229U discloses a plastic magnetic rotor. The device described in the utility model comprises a plastic magnetic body; the plastic magnetic body is provided with multiple sets of impeller blades, each set of impeller blades including two first impeller blades and one second impeller blade; the first impeller blades and the second impeller blades are both configured to have a gradually varying width from wider at the base to narrower at the top; the first impeller blades are longer than the second impeller blades, and the first impeller blades and the second impeller blades form a narrow gap region near the center and a wide gap region away from the center; the wide gap region is provided with a first hole of a special shape arranged according to the width variation of the wide gap region, and the narrow gap region is provided with a second hole of a regular shape. Since the device is provided with multiple sets of impeller blades on the plastic magnetic body, placing the blades at the tail and adding a gap will indirectly reduce its structural strength. Since the rotor is a rotating component, once a structural problem occurs, the device will stop operating, thereby causing a series of other problems. Utility Model Content

Since the rotor is a rotating component, once a structural problem occurs, the equipment will stop operating, thereby causing a series of other problems.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a plastic magnetic rotor with an anti-collision structure, comprising a support frame, a fixing plate, fixing holes, a cooling fan and a fixing rod;

[0006] The support frame is provided with a rotor pole, a fixing rod is provided in the rotor pole, a fixing disk is provided on the left side of the fixing rod, a cooling fan is provided on the fixing disk, and fixing holes are provided in the fixing disk.

[0007] As a preferred technical solution of the present invention, the support frame is formed into a circular ring shape as a whole. The support frame adopts a triangular hollow design. The thickness of the outer ring of the support frame is the same as that of the middle hollow part, but the thickness of the inner ring of the support frame is twice that of the outer ring. The support frame is provided with solid structures at intervals of three centimeters.

[0012] By adopting the above technical solution, the device can closely fit the rotor poles to the support frame through the fixing rod, which can improve the utilization rate of the internal space. Since air is a poor conductor of heat, the heat dissipation efficiency can be improved and the supporting function of the support frame can be guaranteed by reducing the gap.

[0013] As an optimal technical solution of the present invention, a fixed plate is fixedly connected to the left side of the fixed rod, a cooling fan is fixedly connected to the outer ring of the fixed plate, the length of the cooling fan blades is the same as the length of the support frame, the diameter of the fixed plate is the same as the inner ring of the cooling fan, and the fixing hole position opened on the fixed plate is the same as that of the fixing rod.

[0014] By adopting the above technical solution, the device can quickly bear the force of the wind in the supporting frame by forming an air duct through the fixed disk having the same diameter as the inner ring of the cooling fan and the outer ring of the fixed disk fixedly connected to the cooling fan, thereby achieving the purpose of rapid heat dissipation.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The device sets the support frame as a triangular hollow support frame, which can make the support frame have the stability characteristics of a triangle. Combined with the circular ring-shaped enclosed design, it can play a good supporting and buffering effect. The hollow part can increase the heat dissipation area. The fixing rod fits the rotor poles tightly with the support frame, which can improve the internal space utilization.

[0017] 2. The diameter of the fixed disk of the device is the same as the inner ring of the cooling fan. The outer ring of the fixed disk is fixedly connected to the cooling fan, which can quickly force the wind in the support frame and achieve the purpose of rapid heat dissipation by forming an air duct. The rotor poles and the support frame are set to a separated structure, which can not affect the rotor poles and the internal rotating mechanism when the support frame is stressed, thereby ensuring the smooth operation.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-6The technical solution of the utility model is as follows: a plastic magnetic rotor with an anti-collision structure includes a support frame 1; a fixing plate 2; a fixing hole 3; a cooling fan 4; a rotor pole 5 and a fixing rod 6;

[0027] The rotor pole 5 is installed in the support frame 1, and the support frame 1 is formed into a circular ring shape as a whole. The support frame 1 adopts a triangular hollow design. The thickness of the outer ring of the support frame 1 is the same as the middle hollow part, but the thickness of the inner ring of the support frame 1 is twice that of the outer ring. The support frame 1 is provided with a solid structure at a distance of three centimeters. By setting the support frame 1 as a triangular hollow support frame, the device can make the support frame 1 have the stability characteristics of a triangle, and with the circular ring surrounding design, it can play a good supporting and buffering effect. The hollow part can further increase the heat dissipation area. A fixing rod 6 is installed in the rotor pole 5. Three groups of rotor poles 5 are fixedly connected to the inner ring of the support frame 1. The rotor poles 5 are filled with injection molding material. The support frame 1 is rotatably connected to the rotor pole 5. The device can ensure the smooth operation of the support frame 1 by setting the rotor pole 5 and the support frame 1 as a separated structure without affecting the rotor pole 5 and the internal rotating mechanism when the support frame 1 is subjected to force. A fixing disk 2 is provided on the left side of the fixing rod 6;

[0028] The inner ring of the rotor pole 5 is fixedly connected to a fixing rod 6, and the fixing rod 6 tightly fits the rotor pole 5 to the support frame 1. A fixing hole 3 is opened inside the fixing rod 6, and the fixing hole 3 runs through the entire fixing rod 6. The device tightly fits the rotor pole 5 to the support frame 1 through the fixing rod 6, which can improve the internal space utilization rate. Since air is a poor conductor of heat, the heat dissipation efficiency can be improved by reducing the gap and ensuring the supporting function of the support frame 1. A cooling fan 4 is installed on the fixed disk 2, and a fixing hole 3 is opened in the fixed disk 2. The left side of the fixing rod 6 is fixedly connected to the fixing disk 2, and the outer ring of the fixed disk 2 is fixedly connected to the cooling fan 4. The fan blade length of the cooling fan 4 is the same as that of the support frame 1, the diameter of the fixing disk 2 is the same as that of the inner ring of the cooling fan 4, and the fixing hole 3 opened on the fixing disk 2 is the same as the fixing rod 6. The device can quickly force the wind in the support frame 1 by forming an air duct through the same diameter of the fixing disk 2 as the inner ring of the cooling fan 4, and achieve the purpose of rapid heat dissipation.

[0029] Working principle: When using this plastic magnetic rotor with an anti-collision structure, the rotating rod passes through the fixing hole 3 of the fixing rod 6 and starts to rotate under the drive of the internal rotor pole 5. At the same time, the cooling fan 4 on the fixed disk 2 will rotate together, and the heat will be dissipated through the fixed support frame 1. When subjected to external force impact, since the support frame 1 is in a rotational connection with the fixed disk 2 and the rotor pole 5, the force it bears will be offset by the support frame 1. The inner ring thickness of the support frame 1 is twice that of the outer ring, which can ensure sufficient rigidity to ensure stable operation of the rotor pole 5.

[0030] Thereby completing a series of tasks, the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
