The output end of the resistance output component 40 is connected to the bottom end of the bed board 20 through the force transmission component 50, and the intelligent control component 60 is control-connected to the resistance output component 40. The output resistance of the resistance output component 40 can be adjusted by the intelligent control component 60. Compared with the resistance provided by the spring, the adjustment is more convenient and can be adjusted without polarization. Combined with the rolling connection between the bed board 20 and the bed frame 10, the friction coefficient is reduced, so that the bed board 20 moves more smoothly, the noise is low, and the service life is increased. Specifically, the lifting assembly 30 includes a fixed pulley, a pull rope and a soft ring, which is a prior art and will not be described in detail here; the resistance output assembly 40 is a motor, which can be an AC servo motor, a DC servo motor or a DC brushless motor.

[0039] Example 2

[0040] The difference between this embodiment and embodiment 1 lies in the resistance output component 40 and the intelligent control component 60.

An unstable DC voltage can be obtained at both ends of the capacitor C1. The voltage is adjusted to a working voltage that meets the working conditions of the intelligent adjustment module ICS through the voltage adjustment module U1. After the intelligent adjustment module ICS is powered on and started, the fitness user configures parameters through the intelligent adjustment module ICS according to personal needs. The intelligent adjustment module ICS converts the parameters configured by the fitness user into a PWM signal output, and modulates the PWM signal through the photoelectric converter U2 and outputs it to the switch tube Q1. The switch tube Q1 changes the conduction angle according to the electrical signal output by the photoelectric converter U2, and then adjusts the resulting current at both ends of the resistor R4 in real time, thereby achieving the resistance required for exercise.
