AI Technical Summary
The existing multi-functional fitness all-in-one machine uses a separate motor as the power source. When increasing strength, a larger torque motor or reducer must be selected. The lack of a small power motor solves the problem of increasing strength.
A series-connected structure of the low-power motor torque is adopted, and a combination of the motor fixing frame, pulley, belt and pull rope is formed to form a plurality of parallel motor structures. A pulley is provided on each motor housing, and the pulleys of adjacent motors are connected by belts to form a series-connected structure to achieve the high-power effect of the small-power motor.
Through the series structure, the torque concentrated on the end of the draw rope is equal to the sum of the torques of multiple motors, which realizes the function of a small-power motor to achieve a high-power effect, and solves the problem of increasing strength.
