Abstract

The invention belongs to the technical field of mechanical equipment and particularly relates to a hydrocylinder used for a human-assisted walking mechanism. The hydrocylinder comprises a piston rod assembly and further comprises a rear end cover, a cylinder body, a front end cover, a front guide sleeve, a baffle ring, a rear guide sleeve and an end cover which are adjacent to the piston rod assembly and are matched with one another. The piston rod assembly is provided a reciprocating piston. The rear end cover and the front end cover are each provided with an oil port. The hydrocylinder is structurally free of internal and external leakage, small in minimum start-up pressure, high in withstand pressure, long in stroke and high in operational reliability. Meanwhile, the hydrocylinder is simple and compact in structure and convenient to assemble, and the processing technology, tools and the like are high in operability; the applied sealing structure can be applied and popularized to miniature oil cylinders of different cylinder diameters, so mass production and serialized popularization are easy. The hydrocylinder can be used for a human-assisted walking robot and can be also used for an assisted robot which is used for the old and the disabled.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a hydraulic oil cylinder for a human body assisting walking mechanism. Background technique [0002] The human-assisted walking robot is a kind of equipment that can effectively improve the movement and load capacity of soldiers and reduce the oxygen consumption of the human body. Human-assisted walking robots mainly use micro-cylinders as actuators to provide power to carry loads. However, the required micro-cylinders are not produced and sold in China, and cannot be purchased from market channels. The cylinder body of the miniature oil cylinder belongs to the ultra-long thin hole and deep hole, and there are certain difficulties in processing technology, tooling, materials and tests, etc., so it is urgent to design a miniature oil cylinder for the human body power-assisted walking mechanism. The miniature oil cylinder can be used not only in the milita...
