[CN 201910600142.4] Hydraulic mechanism for recovering energy of load-bearing reciprocating motion of human back
[CN 201910600142.4] Title of a hydraulic mechanism for recovering energy of reciprocating motion with weight on the back of human body: Application number of a hydraulic mechanism for recovering energy of reciprocating motion with weight on the back of human body: CN 201910600142.4 Applicant: Xi 'an Jiaotong University Application Date: 2019-7-4 Patent Type: Application for the Invention The present invention discloses a hydraulic mechanism for recovering energy of reciprocating motion with weight on the back of human body. The mechanical energy generated by heavy objects in the backpack during human walking is directly converted into hydraulic energy through a hydraulic cylinder, and the hydraulic energy is stored through an accumulator. The high-pressure hydraulic oil stored in the accumulator directly acts on the actuator of the hydraulic lower limb exoskeleton through a two-position three-way valve. The invention also designs a valve block mechanism that can be directly used to convert mechanical energy generated by reciprocating motion to hydraulic energy, including a valve body and a main valve core with a three-position reversing function, the main valve core pressure regulating spring, the cone valve with dual functions of conduction and locking, and the cone valve pressure regulating spring. The mechanism is all controlled by hydraulic oil, which simplifies the energy exchange electronic control system and the connection of the oil pipe. It is especially suitable for reciprocating movement. The working condition requirements for the conversion of mechanical energy from the characteristic mechanism to hydraulic energy.
