Traditional brush materials include carbon and metal alloys, but in recent years, some new materials have emerged, such as carbon nanotubes, which have better conductivity and wear resistance. The structural design of the brushes needs to take into account the contact with the rotor of the axial motor and a stable mounting structure. This includes the design of the brush shape, size, angle, etc. to ensure good contact with the rotor and to withstand the vibration and pressure of the motor during operation.

[0003] According to a DC motor brush structure (publication number: CN213125701U), it includes a motor end cover, a motor armature is arranged on the motor end cover, a plurality of brush holders are installed on the motor armature, a brush box is arranged on the brush holder, a compression spring is arranged inside the brush box, the bottom of the compression spring is connected to a conductive plate, the bottom of the conductive plate is connected to a carbon brush, a copper sheet is arranged on the carbon brush, a carbon brush braid a and a carbon brush braid b are arranged on the carbon brush, and the bottoms of the carbon brush braid a and the carbon brush braid b are connected to wiring terminals. However, when the brush is damaged in the above design, it is not easy for the staff to replace and install it, and improvement is needed. Utility Model Content

The design of the fixed block 59 is convenient for the staff to pull the fixed plate 63 to drive the sliding block 57 to slide when disassembling the brush 8, thereby moving the support plate 58. At the same time, the fixed block 59 contacts the extrusion block 510, so that the contact block 56 contacts the side inclined surface of the fixed block 59, which is convenient for the staff to disassemble easily.

[0028] The fixed block 59 is located on the movement track of the contact block 56, and the brush 8 is slidably connected to the inner wall of the hollow block 52. The side section of the contact block 56 is trapezoidal. The side section of the contact block 56 is set to be trapezoidal, which is beneficial to drive the spring telescopic rod 54 to extend and retract when the side section of the contact block 56 is squeezed.

[0029] A pulling device 6 is provided on the top of the support plate 58, and the pulling device 6 includes a rectangular block 61, which is fixedly connected to the top of the support plate 58. The top of the rectangular block 61 is rotatably connected to a rotating shaft 62, and the circumferential surface of the rotating shaft 62 is fixedly connected to a fixed plate 63.

When the fixed block 59 contacts the extrusion block 510, the contact block 56 is no longer subjected to the extrusion force, and the spring telescopic rod 54 is reset, thereby driving the contact block 56 to reset. Finally, the staff pulls the fixed plate 63 to drive the support plate 58 to move backward, so that the contact block 56 contacts the other side inclined surface of the fixed block 59. As the staff continues to pull the fixed plate 63, the contact block 56 is squeezed by the other side inclined surface of the fixed block 59 and moves upward to the top of the extrusion block 510. As the contact block 56 is no longer in contact with the top of the extrusion block 510, the staff pulls out the brush 8 sliding on the inner wall of the hollow block 52 to achieve disassembly.
