When the belt 400 is loosened after a period of use, the tension wheel 342 receives a reduced pressure, and the tension spring 343 pulls the lever assembly 341 to tilt, so as to drive the tension wheel 342 to move upwards, so that the tension wheel 342 can provide pressure to ensure that the belt 400 is tensioned.

Further, as shown in fig. 2 and 4, an energizing coil 500 is provided at the middle of the first beam 110 of the bracket 100 and is provided corresponding to the edge of the second transmission assembly 300 to provide a magnetic field cut by the second transmission assembly 300 when the second transmission assembly 300 rotates and provide a rotational resistance to the second transmission assembly 300 using a magnetic interaction.

Specifically, as shown in fig. 4, the energizing coil 500 is disposed corresponding to an edge of the third wheel 330, and the opening of the energizing coil 500 is disposed corresponding to a radial direction of the third wheel 330. Thus, when the energizing coil 500 is energized and the third wheel 330 rotates during riding, the third wheel 330 cuts the magnetic field lines generated by the energizing coil 500 to generate an induced magnetic field, and the magnetic force between the induced magnetic field of the third wheel 330 and the magnetic field generated by the energizing coil 500 provides further resistance adjustment for riding. By changing the current of the energizing coil 500, so as to change the magnetic field strength generated by the energizing coil 500, the magnetic force between the third wheel 330 and the energizing coil 500 changes correspondingly, thus completing the adjustment of riding resistance.

Further, as shown in fig. 4 and 8, a torsion sensor 600 is fixedly provided below the energizing coil 500, and the torsion sensor 600 is abutted against the energizing coil 500 through a bearing 610. Since the torsion sensor 600 is fixed to the bracket 100, the torsion sensor 600 does not move relatively to the bracket 100. In the riding process, since the power-on coil 500 can freely rotate around the second shaft 310, the third wheel 330 rotates to cut the reaction force of the magnetic force received by the power-on coil 500 to the power-on coil 500, which can cause the power-on coil 500 to rotate relative to the second shaft 310, then the torsion sensor 600 can monitor the current torsion data of the user in real time by detecting the force magnitude between the torsion sensor and the power-on coil 500, thereby confirming the resistance received by the current riding, providing reference data for adjusting the resistance magnitude, and being more convenient for the user to confirm the current exercise effect.

By using the speed measuring module 700 and the torsion sensor 600, the real-time riding power of the user can be accurately reflected by the rotating speed of the third wheel 330 and the current torsion data of the user, so that the user can be helped to confirm the physical data better, and the resistance can be adjusted timely as required, thereby achieving a better exercise effect.

Further, as shown in fig. 7 and 9, a control circuit board 800 is disposed on the other side of the connection piece 510 opposite to the power-on coil 500, and the control circuit board 800 is electrically connected to the power-on coil 500, the torsion sensor 600 and the speed measuring module 700, respectively, so as to control the power-on coil 500, the torsion sensor 600 and the speed measuring module 700 to perform corresponding functions and respond corresponding real-time data to the user.

The following specifically describes the operation mode of the direct-drive riding platform of the present utility model:

The flywheel 230 drives the first wheel 220 to rotate through the first shaft 210, and at this time, the diameter difference between the first wheel 220 and the flywheel 230 is utilized to complete the further adjustment of the riding resistance. The first wheel 220 is connected to the second wheel 320 of the second transmission assembly 300 by a belt 400, and drives the second wheel 320 to rotate synchronously. A further level of adjustment of the riding resistance is accomplished by the difference in diameter between the first wheel 220 and the second wheel 320, wherein the tensioning wheel 342 in the tensioning structure 340 ensures that the belt 400 remains tensioned, avoiding slipping.

The second wheel 320 drives the third wheel 330 to rotate through the second shaft 310, and the further stage of adjustment of the riding resistance is completed through the diameter difference between the second wheel 320 and the third wheel 330. The edge of the third wheel 330 is arranged corresponding to the opening of the energizing coil 500, and the magnetic field lines generated after the energizing coil 500 is energized are cut in the rotation process of the third wheel 330, so that an induced magnetic field is generated and forms magnetic interaction with the energizing coil 500, the magnetic interaction between the energizing coil 500 and the third wheel 330 forms resistance to the third wheel 330, and the riding resistance is regulated in a further stage by regulating the magnitude of current in the energizing coil 500. The direct-drive riding platform can realize multistage adjustment on riding resistance through corresponding structural arrangement, greatly expands the resistance adjustment range and is suitable for the needs of different crowds.

Meanwhile, during riding, the torsion sensor 600 is used for monitoring the magnitude of the reaction force received by the power-on coil 500, so that the current torsion is detected in real time; the rotational speed of the third wheel 330 is monitored by the speed measurement module 700 so that the current riding speed is detected in real time.
