[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 A brake device that is easy to maintain includes a rotating disk 10;

[0029] The rotating disk 10 is rotatably connected to the front and rear ends of the limiting disk 11; the opposing sidewalls of the limiting disk 11 are connected to a plurality of driving components 2 arranged in a uniform circular array, the driving components 2 being used to drive the rotating disk 10 to rotate; the inner wall of the rotating disk 10 is fixedly connected to a plurality of brake rollers 13 arranged in a uniform circular array; the opposing sidewalls of the limiting disk 11 are connected to a plurality of floating brake components 3 arranged in a uniform circular array, the inner side of the floating brake components 3 being connected to a rotating roller 34 for braking the outer rotor 12 of the motor.

[0030] In this invention, the drive assembly 2 drives the rotating disk 10 to rotate the brake roller 13. The brake roller 13 drives the rotating roller 34 to move towards the inner side of the outer rotor 12 through the floating brake assembly 3. The rotating roller 34 abuts against the outer wall of the outer rotor 12 to brake the outer rotor 12. The outer rotor 12 drives the rotating roller 34 to rotate, reducing the wear between the rotating roller 34 and the outer rotor 12, extending the service life, and facilitating maintenance.

[0031] The drive assembly 2 includes a mounting block 21, an electromagnet 22, and a magnetic block 23. The opposing sidewalls of the limiting disk 11 are fixedly connected to the front and rear ends of the mounting block 21, respectively. An electromagnet 22 is fixedly connected to the sidewall of the mounting block 21, and the electromagnet 22 is electrically connected to the motor controller. The electromagnet 22 is a de-energized magnet. A magnetic block 23 is fixedly connected to the inner sidewall of the limiting disk 11.

[0032] The floating braking assembly 3 includes a limiting block 32 and a spring 33. The opposing sidewalls of the limiting disc 11 are provided with limiting grooves 31. The top of each limiting groove 31 is fixedly connected to a spring 33, and the lower end of the spring 33 is fixedly connected to a limiting block 32. The limiting block 32 and the limiting groove 31 are slidably connected. The opposing sidewalls of the two limiting blocks 32 are rotatably connected to both ends of the rotating roller 34. The mounting block 21, electromagnet 22, magnetic block 23, brake roller 13 and rotating roller 34 are arranged in a clockwise direction. The distance from the innermost end of the brake roller 13 to the outer wall of the outer rotor 12 is less than the distance from the outermost end of the rotating roller 34 to the outer wall of the outer rotor 12. The distance from the innermost end of the brake roller 13 to the outer wall of the outer rotor 12 is less than the diameter of the rotating roller 34.

[0033] In this invention, when braking the outer rotor 12 of the motor is required, the controller is de-energized, causing the electromagnet 22 to lose power and acquire magnetism. The electromagnet 22 drives the magnetic block 23 to rotate the rotating disk 10 clockwise. Since the distance from the innermost end of the brake roller 13 to the outer wall of the outer rotor 12 is less than the distance from the outermost end of the rotating roller 34 to the outer wall of the outer rotor 12, the side wall of the brake roller 13 abuts against the side wall of the rotating roller 34. Thus, the brake roller 13 drives the rotating roller 34 to move the limiting block 32 inward along the side wall of the limiting groove 31. When the spring 33 is stretched and the side wall of the rotating roller 34 abuts against the outer wall of the outer rotor 12, the outer rotor 12 drives the rotating roller 34 to rotate. The brake roller 13 abuts against the rotating roller 34 and reduces the speed of the rotating roller 34 through friction. Thus, the rotating roller 34 reduces the speed of the outer rotor 12 through friction, thereby braking the outer rotor 12. The outer rotor 12 drives the rotating roller 34 to rotate, preventing... The single-point disengagement of the rotating roller 34 prevents wear between the outer rotor 12 and the rotating roller 34, facilitating later maintenance. Furthermore, the distance from the innermost end of the brake roller 13 to the outer wall of the outer rotor 12 is less than the diameter of the rotating roller 34, ensuring that the brake roller 13 is always located counter-clockwise from the rotating roller 34, preventing the brake roller 13 from moving past the dead point and causing device failure. After the controller is powered on again, the electromagnet 22 loses its magnetic force on the magnetic block 23. Since the distance from the innermost end of the brake roller 13 to the outer wall of the outer rotor 12 is less than the diameter of the rotating roller 34, the brake roller 13 and the rotating roller 34 are not at the dead point. At this time, the spring 33 drives the rotating roller 34 to move upwards to reset, and the rotating roller 34 drives the limit block 32 to move upwards to reset. The rotating roller 34, through the brake roller 13, drives the rotating disk 10 to rotate and reset, releasing the brake on the outer rotor 12 and achieving automatic reset of the rotating disk 10.

[0034] In this invention, when the controller is powered off, the electromagnet 22 becomes magnetic. The electromagnet 22 drives the magnetic block 23 to rotate the rotating disk 10 clockwise. This, in turn, drives the rotating roller 34 to move inward via the brake roller 13, thus braking the outer rotor 12 and preventing safety accidents caused by the equipment continuing to move due to inertia. The distance from the innermost end of the brake roller 13 to the outer wall of the outer rotor 12 is less than the distance from the outermost end of the rotating roller 34 to the outer wall of the outer rotor 12, ensuring that the clockwise rotation of the brake roller 13 can drive the rotating roller 34 inward. The movement of the outer rotor 12 achieves braking of the outer rotor 12; the two ends of the rotating roller 34 are rotatably connected to the limit block 32, so that the outer rotor 12 drives the rotating roller 34 to rotate, avoiding the wear of the outer rotor 12 and the rotating roller 34 caused by the rotating roller 34 always being disengaged from the rotating roller 34 at a single point, extending the service life and facilitating later maintenance; the distance from the innermost end of the brake roller 13 to the outer wall of the outer rotor 12 is less than the diameter of the rotating roller 34, preventing the brake roller 13 from passing the dead point when rotating clockwise, and ensuring that the brake roller 13 automatically resets after the controller is powered off.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
