[0002] A magnetic control wheel is a device that works using the principle of magnetic fields. It features non-contact power transmission, precise control, high efficiency, and safety and reliability. Magnetic control wheels are used in many fields such as fitness equipment, transportation vehicles, and industrial equipment. When using a magnetic control wheel, it needs to be paired with a braking device to assist in braking the magnetic control wheel.

The required buffer distance and time for braking are poor. At the same time, the brake pads are fixed in position, which generates a large friction force when braking, causing serious wear on the brake pads and magnetic control wheel, and affecting the service life of the brake pads and magnetic control wheel.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figure 2 and Figure 3As shown in this embodiment, a magnetically controlled wheel braking device includes a magnetically controlled wheel body 1, a fixed disk 2, a braking assembly 3, and a driving assembly 4. The fixed disk 2 is disposed on one side of the magnetically controlled wheel body 1, the braking assembly 3 is mounted on one side of the fixed disk 2, and the driving assembly 4 is mounted on one side of the magnetically controlled wheel body 1.

The transmission column 5 is rotatably mounted on the side wall of the fixed disk 2, and the fixing frame 6 is mounted on... Mounted on the side wall of the fixed plate 2, the first lead screw 7 is rotatably mounted on the side wall of the fixed frame 6. Two sets of transmission wheels 8 are respectively sleeved and mounted on the outside of the transmission column 5 and the first lead screw 7. The transmission belt 9 is sleeved and mounted on the outside of the transmission wheels 8. Two sets of first lead screw nuts 10 are symmetrically sleeved and mounted on the outside of the first lead screw 7. The first brake pad 11 is mounted on the bottom of the first lead screw nut 10. Multiple sets of sliding grooves 12 are formed on the surface of the fixed plate 2. The damper 13 is set in the sliding groove 12. Multiple sets of connecting columns 14 are slidably set in the sliding groove 12. The fixed frame 6 has an L-shaped cross-section. The surface of the first lead screw 7 is formed with... There are two sets of external threads, which are arranged in opposite directions. The first lead screw nut 10 is slidably disposed with the fixed frame 6. The first brake pad 11 is symmetrically disposed on the side wall of the magnetic control wheel body 1. Multiple sets of sliding grooves 12 have an arc-shaped structure and are concentrically disposed with the transmission column 5. The connecting column 14 is connected to the damper 13. When the magnetic control wheel body 1 is initially braked, the inertial force of the magnetic control wheel body 1 causes the stabilizing frame 15 to rotate. The rotation of the stabilizing frame 15 drives the transmission column 5 and the connecting column 14 to rotate. With the arrangement of the sliding grooves 12 and the damper 13, the connecting column 14 slides within the sliding grooves 12 and... The speed is relatively slow. The rotation of the transmission column 5 drives the transmission wheel 8 to rotate. Under the transmission of the transmission belt 9, the rotation of the transmission wheel 8 drives another set of transmission wheels 8 to rotate. The rotation of the other set of transmission wheels 8 drives the first lead screw 7 to rotate forward. The rotation of the first lead screw 7 drives the two sets of first lead screw nuts 10 to move closer to each other. The movement of the first lead screw nuts 10 drives the first brake pad 11 to move and fit against the side wall of the magnetic control wheel body 1, thus completing the braking of the magnetic control wheel body 1 and achieving a good braking effect. At the same time, it reduces the friction between the first brake pad 11 and the second brake pad 19 and extends the service life of the first brake pad 11 and the second brake pad 19.

The stabilizing frame 15 is installed at one end of the transmission column 5. The drive motor 16 is bolted to the side wall of the stabilizing frame 15. The second lead screw 17 is installed at the output end of the drive motor 16. The two sets of second lead screw nuts 18 are symmetrically sleeved on the outside of the second lead screw 17. The second brake pad 19 is installed on the side wall of the second lead screw nut 18. The stabilizing frame 15 has a U-shaped cross-section. The surface of the second lead screw 17 has two sets of external threads, which are arranged in opposite directions. The second lead screw nuts 18 are slidably disposed with the stabilizing frame 15. The drive motor 16 drives the second lead screw 17 to rotate forward. The rotation of the second lead screw 17 causes the two sets of second lead screw nuts 18 to move closer to each other. The movement of the second lead screw nuts 18 causes the second brake pad 19 to move and fit against the outer wall of the magnetic control wheel body 1, thus completing the initial braking of the magnetic control wheel body 1.

[0022] This utility model provides a magnetically controlled wheel braking device, the specific working principle of which is as follows:

[0023] When using this magnetically controlled wheel braking device, the fixed disk 2 is fixedly connected to the existing structure near the magnetically controlled wheel body 1. With the drive assembly 4, when braking the magnetically controlled wheel body 1 is required, the drive motor 16 is started. The drive motor 16 drives the second lead screw 17 to rotate forward. The rotation of the second lead screw 17 causes the two sets of second lead screw nuts 18 to move closer together. The movement of the second lead screw nuts 18 causes the second brake pad 19 to move and come into contact with the outer wall of the magnetically controlled wheel body 1, completing the initial braking of the magnetically controlled wheel body 1. With the braking assembly 3, during the initial braking of the magnetically controlled wheel body 1, the inertial force of the magnetically controlled wheel body 1 causes the stabilizing frame 15 to rotate. The rotation of the stabilizing frame 15 drives the transmission column 5 and the connecting column 14 to rotate. With the sliding groove 12 and damper 13 in place, the connecting column 14 slides slowly within the sliding groove 12. The rotation of the transmission column 5 drives the transmission wheel 8 to rotate. Under the transmission of the transmission belt 9, the rotation of the transmission wheel 8 drives another set of transmission wheels 8 to rotate. The rotation of the other set of transmission wheels 8 drives the first lead screw 7 to rotate forward. The rotation of the first lead screw 7 drives the two sets of first lead screw nuts 10 to move closer to each other. The movement of the first lead screw nuts 10 drives the first brake pad 11 to move and fit against the side wall of the magnetic control wheel body 1, thus completing the braking of the magnetic control wheel body 1 and achieving a good braking effect. At the same time, it reduces the friction between the first brake pad 11 and the second brake pad 19, extending the service life of the first brake pad 11 and the second brake pad 19.
