Set up the joint skeleton in the rectangle cavity, joint framework two ends respectively with upper end cover, bottom end cover fixed connection, set up the gasbag in the tubulose cavity, the gasbag both ends are connected with upper cover, low head respectively, are equipped with the fluid entry on the low head. The utility model discloses an articular drive arrangement and the integrative structure of the compound formation of joint body are equivalent to that two pneumatic artificial muscle are parallelly connected, have 1 degree of freedom, can realize the initiative bending of single orientation in the bionical joint.
Description
Technical field
The present invention relates to mechanical hand and bio-robot limbs flexible joint, particularly to a kind of Dual Drive Pneumatic unidirectional bending flexible joint.
Background technology
Current robotics is widely used in fields such as industry, military, medical treatment and services, it has also become one of grand strategy support technology of countries in the world.As key technology and the core component of robot, the diarthrodial structure of all kinds of masters, driving, exercise performance and control method, the integral level of robot will be determined.In terrestrial, aquatic and anthropomorphic robot field, limbs flexible joint has important function in solving the adaptability of compliant motion and crawl object.Therefore, conducting in-depth research and achieve gratifying results to flexible joint both at home and abroad for many years, the main contents of research have the realization of articulated driving equipment, driving material and flexibility of joint structure.Wherein joint drive structure and control mode are research emphasis, and driving material is Research Challenges.
The flexible joint researched and developed both at home and abroad mainly has several forms such as driven by servomotor, hydraulic-driven, air cylinder driven, conducting polymer, electroluminescent driving and artificial-muscle driving.Wherein applying the flexible joint of driven by servomotor, hydraulic pressure and cylinder type of drive, its technology is mature on the whole, and is widely used, but volume is relatively big, and flexibility of joint degree is restricted；And conducting polymer and electroluminescent driving stroke are less, it is mainly used in amphiarthrosis；Pneumatic artificial muscle drives to be had preferably comprehensive flexible, is developed rapidly in recent years, but has stronger non-linear.Several driving devices will be big with the use of, volume with frame for movement in application process above, and miniaturization difficult, the movement locus in joint is determined by frame for movement, and compliance is poor.
Therefore, current existing artificial joint still can not fully meet the special requirement in the fields such as bionical in the bigger carrying of industrial goods of variation, water and specialized robot, it is necessary to continual exploitation has the joint of highly flexible.
Summary of the invention
It is an object of the invention to overcome the deficiency of prior art, it is provided that a kind of robot limb Dual Drive Pneumatic unidirectional bends flexible joint.
A kind of Dual Drive Pneumatic unidirectional bending flexible joint of the present invention, including confinement element, joint skeleton, air bag, upper end cover, bottom end cover, upper cover, low head, fluid intake, several confinement elements it are provided with between upper end cover and bottom end cover, several confinement elements described coaxially connect solid matter formed column structure?Column structure is internally formed 1 rectangular enclosure and the parallel tubular cavity of 2 axis.Arranging joint skeleton in rectangular enclosure, joint skeleton two ends are fixed with upper end cover, bottom end cover respectively and are connected；Arranging air bag in tubular cavity, balloon ends is connected with upper cover, low head respectively, constitutes and seals cavity；Upper cover, low head and upper end cover, bottom end cover are fixedly connected into one, are provided with fluid intake on low head.
Described joint adopts two air bags to be driven.
Described low head is provided with fluid intake, with charged pressure fluid, increase when being filled with fluid pressure, annular seal space volume expansion promotes confinement element to move and makes joint active deformation increasing, reduce when being filled with fluid pressure, rubber pneumatic bag recovers, and joint deformity reduces, and deformation is relevant with described bound form and logical pressure condition；When skeleton is flexible member, and 2 air bag venting pressures are identical, there is one direction actively bending in joint, flexural deformation degree is determined by fluid medium pressure, described in be filled with fluid, it is possible to be medium corrosion-free, avirulent, as compressed sky gas and water etc..
It is an advantage of the invention that arthritic volume is little and motion is flexible, the driving device in joint and joint body are complex as a whole, and are equivalent to two Pneumatic artificial muscle parallel connections, have 1 degree of freedom, it may be achieved the active bending in the single direction of bionic joint；This joint belongs to the flexible joint of fluid drives deformation, and a proportioning valve and two reversal valves can be adopted to carry out action control, and method is simply easily achieved；As action executing element, owing to its structure is mainly composite elastic body, when contacting difformity and different hardness objects, adaptability meeting is better and has certain buffering effect, can be used on the joints such as bionic mechanical hand finger, it is particularly suited for capturing or carrying rapid wear, frangible and erose object, there is good using value and market prospect.
