In addition, the conventional treadmill is used in conjunction with the cushioning auxiliary structure. A resistance device that applies resistance to the rotation of the running belt of the machine.

However, although the resistance device of the conventional treadmill can manually select the resistance according to personal conditions and the type of exercise performed, the resistance is mostly generated by controlling the motor, and the resistance is in a fixed mode (until the resistance is changed manually or End exercise), the resistance cannot be automatically adjusted dynamically during exercise, so not only the motor consumes a large amount of power, it causes energy waste, and the motor is easily overheated and damaged, resulting in a shortened motor life.

In view of the above-mentioned shortcomings of the resistance device of the conventional treadmill, the creator of this creation is based on the idea of thinking and creation. After many discussions and trial samples, as well as many modifications and improvements, he launched this creation.

This creation provides a dynamic resistance compensation system for a motion mechanism, including: a motor, the motor includes a motor body and a rotating shaft, the motor body is provided with a transmission end and a sensing end opposite to the transmission end, the rotation shaft is arranged on One end of the center of the motor body penetrates the transmission end of the motor body; a sensing device is installed on the sensing end of the motor body to sense the rotation angle and speed of the motor shaft through magnetic force; And a control device, electrically connected to the sensing device and the motor, for receiving the sensing information of the sensing device in real time, and the control device performs dynamic power compensation on the motor, thereby generating the corresponding motion mechanism Dynamic resistance.

The main purpose of the dynamic resistance compensation system of the creative motion mechanism is that when the motion mechanism is for the user to exercise, the motor resistance can be dynamically adjusted automatically, so that not only the power consumption of the motor is small, but energy is saved, and the motor is not damaged. Damaged by overheating, the motor has a long service life.

The motor 20 includes a motor body 21 and a rotating shaft 22. The motor body 21 is provided with a transmission end 211 and a sensing end 212 opposite to the transmission end 211. The rotation shaft 22 is arranged at the center of the motor body 21 and one end passes through The transmission end 211 of the motor body 21 is linked with the front wheel set 12 of the treadmill 10 through a transmission device 23.

The sensing device 30 is mounted on the sensing end 212 of the motor body 21 and fixed to sense the rotation angle and rotation speed information of the rotating shaft 22 of the motor 20 through the magnetic force.

The control device 40 is electrically connected to the sensing device 30 and the motor 20, and is installed on the frame 11 of the treadmill 10 to receive the sensing information of the sensing device 30 in real time, and the control device 40 performs dynamic power compensation on the motor 20 to generate dynamic resistance corresponding to the motion mechanism. .

When in use, when an exerciser is running on the running belt 13 of the treadmill 10, the force applying element 141 can be used for the user's hand to hold to maintain running stability. The force applying element 141 can conform to the user's forward abutment Pushing displacement, and as the force-applying element 141 pushes forward and generates relative resistance, it reaches the position that restricts the user from running on the treadmill 10. At the same time, it can perform hand movement and simulate the weight training of pushing the weight forward. The effect of training the core muscles.
