Hydraulic actuating mechanism and method for recycling energy

The invention discloses a hydraulic actuating mechanism and method for recycling energy. The actuating mechanism comprises an electric power storage device, a motor controller, a motor, an element, a first hydraulic control one-way valve, a second hydraulic control one-way valve, a hydraulic cylinder and a hydraulic oil tank. The hydraulic actuating mechanism and method for recycling energy can be used for converting the electric energy stored in the electric power storage device to the kinetic energy of the hydraulic piston rod and also converting the kinetic energy of the hydraulic piston rod to the electric energy stored in the electric power storage device so as to achieve the purposes of recycling energy and saving resources. The hydraulic actuating mechanism and method for recycling energy have a favorable application prospect on engineering machinery in the technical field of engineering.
