Problems solved by technology

[0003] However, the two-degree-of-freedom joint structure of the robot in the prior art has inherent defects, such as large structure, high manufacturing cost, low structural integration, low strength, inaccurate positioning, difficult control, and low load capacity. Both limit the development of bionic robots, and are not convenient for the popularization and use of two-degree-of-freedom joint structures

Abstract

The invention relates to the technical field of multi-freedom-degree joints, in particular to a two-freedom-degree joint structure. The two-freedom-degree joint structure comprises a U-shaped fixed plate, a U-shaped connecting plate, a first-freedom-degree mechanism and a second-freedom-degree mechanism arranged on the U-shaped connecting plate, wherein the U-shaped fixed plate and the U-shaped connecting plate can rotate oppositely. A bottom plate of the U-shaped fixed plate and a bottom plate of the U-shaped connecting plate are arranged oppositely. A first side plate of the U-shaped connecting plate is connected to the inner side of a first side plate of the U-shaped fixed plate through the first-freedom-degree mechanism. A second side plate of the U-shaped connecting plate is rotationally connected to the inner side of a second side plate of the U-shaped fixed plate. The two-freedom-degree joint structure is simple in structure, reasonable in design, convenient to mount, use and control, high in universality and practicability, long in service life and convenient to use and popularize.

Description

technical field [0001] The invention relates to the technical field of multi-degree-of-freedom joints, in particular to a two-degree-of-freedom joint structure. Background technique [0002] With the development of robot technology, the types of robots are increasing, and the requirements for the flexibility, compactness, intelligence and controllability of robot joints are getting higher and higher. A two-degree-of-freedom joint refers to a joint with two degrees of freedom perpendicular to each other. Prototypes of such joints are ubiquitous in humans and animals, such as neck joints, wrist joints, ankle joints, and finger joints of humans and other walking animals. , waist joints, leg joints of crabs and other reptiles, etc. Therefore, for various bionic robots, making joints with two degrees of freedom is one of the problems to be solved. [0003] However, the two-degree-of-freedom joint structure of the robot in the prior art has inherent defects, such as large struct...
