[0004] In the above solution, the bushing is arranged in the magnetic ring hole of the magnetic ring, but there is no fixed structure between the bushing and the magnetic ring, which leads to the bushing and the magnetic ring being easily loose, thereby affecting the use effect of the motor. Therefore, a magnetic ring assembly of an AMT motor is proposed. Utility Model Content

[0005] In view of the above problems existing in the magnetic ring assembly of the existing AMT motor, the present utility model is proposed.

[0006] Therefore, the purpose of the utility model is to provide a magnetic ring assembly for an AMT motor, which solves the problems raised by the background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A magnetic ring assembly of an AMT motor includes a magnetic ring and a bushing, wherein the bushing is located inside the magnetic ring, a sliding opening is provided on the side wall of the bushing, a slider is provided inside the sliding opening, a spring is fixedly provided on one side of the slider, and an end of the spring away from the slider is fixedly connected to the side wall of the sliding opening, a fixed plug rod is fixedly provided on the side of the slider away from the spring, and a fixed slot matching the fixed plug rod is provided on the inner side wall of the magnetic ring.

[0009] Preferably, finger grooves are provided on both sides of the slider.

[0010] Preferably, there are two sliding openings, and the two sliding openings are symmetrically distributed up and down.

[0011] Preferably, positioning blocks are fixedly provided on both sides of the bushing, and the side walls of the magnetic ring are provided with positioning slots matched with the positioning blocks.

[0012] Furthermore, the bushing adopts a PVC sleeve.

[0013] Preferably, the positioning plug and the bushing are integrally formed.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] The utility model has a slider, a spring and a fixed insertion rod arranged on the bushing. The spring exerts elastic force on the slider due to the elastic force, so that the slider drives the end of the fixed insertion rod to extend and insert into the fixed slot on the inner wall of the magnetic ring. At this time, the bushing and the magnetic ring can be clamped and fixed.

[0016] The utility model provides a positioning block and a positioning slot between the bushing and the magnetic ring. When the bushing is installed inside the magnetic ring, it is necessary to align the position of the fixed plug rod with the fixed slot. At this time, the positioning block cooperates with the positioning slot, so that the fixed plug rod can be automatically aligned with the fixed slot, which is convenient for plugging and fixing.
