Problems solved by technology

[0002] Before the present invention was made, in the prior art, for bending joints: generally, various types of motors or hydraulic pressure were used as power, and combinations of various mechanical structures, hydraulic cylinders, motors, etc. were used as actuators; the above methods were Rigid structure, high precision control requirements, complex structure, large volume, high manufacturing cost
In particular, the joints of existing manipulators and robots do not have the characteristics of multi-directional bending, and cannot reflect the characteristics of animal joint flexibility, flexibility and multi-joint coordination

Embodiment Construction

[0035] Below the present invention will further describe the implementation of various modes in conjunction with accompanying drawing:

[0036] (1) Artificial muscle components

[0037] as attached Figure 1~2 As shown, the elastic bellows 3 is clamped on the bayonet of the headstock 1 and the tailstock 4 by the ferrule 2, and the elastic bellows 3, the headstock 1 and the tailstock 4 form a closed cavity; the fluid passes through the hose 7 and the The right-angle joint 6 enters the joint cavity, and there is a sealing ring 5 between the right-angle joint 6 and the tailstock 4; Guide grooves 8 with the same size; an independent fluid-driven artificial muscle assembly is formed by the above-mentioned parts.

[0038] The elastic bellows 3 is a rubber bellows, and the longitudinal section shape of the single-section elastic bellows can be in the shape of "V", "U", "Ω" and so on; wherein the elastic bellows 3 with a "V" cross-section are as attached Figures 17-18 As shown, al...

Abstract

The present invention relates to a combinatory muscle type flexible joint capable of bending toward several directions. It can be used as various joints of robot and artificial limb. Said flexible joint adopts the axial expasion of elastic corrugated pipe after which is forced by fluid pressure as muscle power, several artificial muscle components are formed into said flexible joint. It adopts plate spring or plate hinge as flexible joint skeleton capable of bending toward two directions, and adopts bar spring and ball universal joint or cross universal joint as flexible joint sekelton capable of bending toward several directions.

Description

Technical field: [0001] The invention relates to a flexible joint with multi-directional bending of combined muscles, which can be used as various joints of robots, manipulators and prosthetics for the disabled, especially robot joints that need to be bent in multiple directions like the arm joints of the human body , as an actuator of automation equipment, belongs to the technical field of robot and manipulator application. Background technique: [0002] Before the present invention was made, in the prior art, for bending joints: generally, various types of motors or hydraulic pressure were used as power, and combinations of various mechanical structures, hydraulic cylinders, motors, etc. were used as actuators; the above methods were The rigid structure requires high control precision, and the structure is complicated, the volume is large, and the manufacturing cost is high. Especially the joints of existing manipulators and robots do not have the characteristics of multi...
