Embodiment Construction
[0055] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0056] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
[0057] In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity of indic...

The invention discloses a hydraulic driving system, a hydraulic driving method and an exoskeleton, and relates to the technical field of human motion auxiliary equipment. The flexibility is improved and the energy consumption is reduced. The hydraulic driving system comprises a liquid supply unit, a first hydraulic cylinder, a first control valve unit, a second hydraulic cylinder and a second control valve unit. The liquid supply unit is used for outputting hydraulic oil to drive the first hydraulic cylinder and the second hydraulic cylinder. The first control valve unit is used for controlling the flow of the hydraulic oil supplied to the first hydraulic cylinder by the liquid supply unit. When the wearer stands, the first control valve unit controls the first hydraulic cylinder to be in an extending state. When the wearer walks, the first control valve unit controls the first hydraulic cylinder to be in a stretching / bending circulation state. The second control valve unit is used for controlling the flow of the hydraulic oil supplied to the second hydraulic cylinder by the liquid supply unit. When the wearer stands, the second control valve unit controls the second hydraulic cylinder to be in the extending state. When the wearer walks, the second control valve unit controls the second hydraulic cylinder to be in the stretching / bending circulation state.
Description
technical field [0001] The invention relates to the technical field of human body motion auxiliary equipment, in particular to a hydraulic drive system, a hydraulic drive method and an exoskeleton. Background technique [0002] Exoskeleton is a new type of wearable human-machine integration device, which is mainly used in military operations and rehabilitation medical fields. When the exoskeleton is used in the field of military combat, it can improve the combat capability of individual soldiers while improving the strength, speed and endurance of soldiers. [0003] At present, the drive system of exoskeleton robots mainly includes hydraulic drive system, motor drive system and pneumatic drive system. Among them, the hydraulic drive system is widely used in heavy-duty exoskeletons because it can output a large torque. [0004] However, the hydraulic drive system applied to the heavy-duty exoskeleton has problems of poor flexibility and high energy consumption when the wear...
