Detailed Description

When an element (or a unit or a module, etc.) is "disposed," "connected" or "coupled" to another element, it can mean that the element is directly disposed, connected or coupled to the other element, or that the element is indirectly disposed, connected or coupled to the other element, i.e., that there are other elements between the element and the other element. When an element is explicitly described as being "directly disposed," "directly connected" or "directly coupled" to another element, it is not intended that another element be interposed between the element and the other element.

The terms first, second, third, etc. are used for describing different elements only, and the elements themselves are not limited, so the first element can be also called the second element. And the combination of elements/units/circuits herein is not a commonly known, conventional or existing combination in this field, and cannot be easily determined by a person skilled in the art whether the combination is easily accomplished by the person skilled in the art based on whether the elements/units/circuits are existing.

electromagnet elements

132, 133 are energized to generate a magnetic field. When the moving component 120 is driven and moves the magnetic resistor 131, the magnetic resistor 131 is influenced by the magnetic fields of the

electromagnet elements

132, 133 to generate resistance to the moving component 120. The electromagnetic damping group 130 formed by the

The tension adjusting member 150 is movably in contact with a surface of the torque transmission belt 134 and is used to adjust the tension of the torque transmission belt 134. Specifically, the tension adjusting element 150 may be a tension adjusting idler pulley or other element that can be used to adjust the tension, but the invention is not limited thereto. Accordingly, the torque output transmitted through the torque transmission belt 134 can be further adjusted.

Further, the electromagnet element 132 may be disposed inside the magnetoresistor 131. Specifically, the number of the electromagnet elements 132 is two, and the electromagnet elements 132 are fixed in two opposite sides of the magnetic resistor 131, when the electromagnet elements 132 are energized, a magnetic field is generated, and when the user operates the handle 121 and drives the output shaft of the magnetic resistor 131 to rotate through the torque transmission belt 134 to drive the magnetic resistor 131 to rotate, the magnetic field attracts the magnetic resistor 131, thereby providing a reverse resistance to the load effect required by the user during the exercise.

electromagnetic elements

243 and 244, and a torque transmission belt 242. The magnetoresistor 241 has an output shaft. The

electromagnet elements

electromagnet elements

243 and 244 are used to generate a magnetic field when being energized. The torque transmission belt 242 connects the reel 220 and the output shaft. When the torque transmission belt 242 is driven and connects the output shaft of the magnetic resistor 241, the magnetic resistor 241 is influenced by the magnetic fields of the

electromagnet elements

243 and 244 to generate resistance to the torque transmission belt 242. The tension adjusting element 260 is movably in contact with a surface of the torque transmission belt 242 and is used to adjust the tension of the torque transmission belt 242.

Specifically, the

electromagnet elements

243, 244 may be adjacently disposed to the magnetoresistor 241. As shown in fig. 2, the electromagnet element 243 includes two electromagnet coils and a bracket, and is disposed in the magnetic resistor 241, and the output shaft of the magnetic resistor 241 penetrates through the bracket of the electromagnet element 243, and the bracket of the electromagnet element 243 fixes the two electromagnet coils at two ends of the magnetic resistor 241, but the present invention is not limited thereto. In other embodiments, the bracket may respectively fix four electromagnet coils at four corners of the magnetoresistor, and the present invention is not limited to the number of the electromagnet coils. Thus, the torque output of the magnetoresistor 241 may be adjusted.

Furthermore, the electromagnet element 244 is disposed outside the magnetoresistor 241. The electromagnet element 244 may be a solenoid electromagnet, and the magnetic force line of the solenoid of the electromagnet element 244 is directed to the center of the magnetic resistor 241, but the present invention is not limited thereto. The electromagnet 244 disposed outside the magnetic resistor 241 can further provide a larger torque output, thereby enhancing the torque output of the magnetic resistor 241.

Furthermore, the exercise apparatus 200 may further comprise a spiral spring 250 connected to the reel 220. Thus, when the user pulls the motion cable 230, the wrap spring 250 is forced to stretch, and when the user pushes back the motion cable 230, the wrap spring 250 helps the user push back the motion cable 230 and pulls the cable 232 back into the winder 220, thereby increasing the smoothness of the user pushing back the motion cable 230.
