Abstract: The invention discloses an energy storage device, comprising a mounting seat, a first spring energy storage component, a second spring energy storage component, a one-way limiter, a transmission component, and a generator; the first spring energy storage component comprises a first rotating shaft, a first spring, and a first spring barrel; the second spring energy storage component comprises a second rotating shaft, a second spring, and a second spring barrel. The device uses two spring energy storage components to collect the gravitational potential energy of different dispersion points at the same time, and store it in the corresponding spring, then through the action of the one-way limiter, the energy of the spring with larger energy storage can be released and converted into electrical energy.

Abstract: The invention discloses a tension force stepless adjustment counterweight power generating mechanism and a fitness equipment with the same, comprising a pulling rope, a winding drum, a mounting seat, a central shaft, a spring, a generator, and a regulator; one end of the pulling rope is connected to the winding drum; a part of the pulling rope is wound on the outer peripheral wall of the winding drum; the winding drum is rotatably connected to the mounting seat; the outer end of the spring is connected to the winding drum, and the inner end thereof is connected to the mounting seat; the central shaft is rotatably arranged on the mounting seat. The mechanism organically combines the pulling force process with the power generation process, and uses a regulator to adjust the rotation damping of the generator motor shaft to adjust the pulling force in a disguised manner.
