Abstract: A transmission structure of a climbing machine for an operator to operate in a standing position is disclosed. The transmission structure of the climbing machine includes a base, a support frame, a first slide rail, a second slide rail, a first transmission unit, a second transmission unit, a first handle slider, a first pedal slider, a second handle slider, a second pedal slider, and a resistance unit. The climbing machine is used to train the synchronized and coordinated movements of hands and feet for simulating rock climbing and mountaineering. The support frame, the first slide rail, the second slide rail, the first transmission unit and the second transmission unit are all located at the center line position of the upright trunk of the operator. The volume of the climbing machine can be reduced greatly to save the space occupied.

Abstract: A slide structure of an exercise machine comprises a slide seat, configured to be movable along an axial direction relative to a slide rail; a roller, rotatably coupled to the slide seat; a dry-running limit slider, having a bushing seat and a dry-running bushing, the dry-running bushing embracing the slide rail on a vertical plane perpendicular to the axial direction. The slide seat moves on the slide rail along the axial direction through the roller to roll along the axial direction, the dry-running limit slider to slide along the axial direction, and the dry-running limit slider to limit the displacement of the slide seat on the vertical plane.

Abstract: An electric magnetic resistance control structure for an exercise machine includes a base; a flywheel, pivotally connected to the base through a rotating shaft, the rotating shaft defining an axial direction, the flywheel, a non-magnetically sensitive layer being coupled to a circumference of the flywheel; a power unit, fixed to the base; a magnetic resistance unit, including a coupling portion corresponding to an arc of the non-magnetically sensitive layer, at least one magnetic member being provided on the coupling portion and kept at a distance from the non-magnetically sensitive layer to generate a magnetic resistance effect; a control unit, configured to control a current applied to the power unit to drive the magnetic resistance unit to move along the axial direction, thereby changing an overlapping area of the magnetic member and the non-magnetically sensitive layer in the axial direction, so as to adjust a magnetic resistance of the flywheel.
