Problems solved by technology

[0003] The purpose of the present invention is to propose a kind of external frame structure for the detection of shoulder motion in view of the disadvantages of the existing human arm joint motion detection device, such as complex system, bloated structure, large detection error, and difficult maintenance. The link has a brand-new design, using a unique connection method and ingenious joint measurement point layout, which greatly simplifies the complex control system of the human arm joint motion detection device, so that the operator can maintain the maximum flexibility of the arm when using the device , and the motion state of the shoulder joint can be accurately detected, so that the controlled slave hand joint can act in unison with the corresponding arm joint of the operator, enhancing the sense of presence in virtual reality or teleoperation

specific Embodiment approach 1

[0013] Specific implementation mode one: as figure 1 As shown, the human upper arm abduction and adduction motion detection device includes an upper arm fixing device 102 , connecting rods 2 - 1 , 2 - 2 , a shoulder detection device 101 , and a shoulder base 1 . The upper arm fixing device 102 is fixed on the operator's upper arm, the shoulder detection device 101 is composed of two sets of joint detection components 105-1 and 105-2, and the shoulder detection device 101 is fixed on the shoulder base 1 , the shoulder base 1 is fixed on the operator's shoulder, the shoulder detection device 101 and the upper arm fixing device 102 are hinged through two-stage connecting rods 2-1, 2-2, and the abduction and adduction motion detection device of the upper arm of the human hand is connected to the operator's arm. The detection of shoulder joint motion is carried out by joint detection parts 105-1 and 105-2.

specific Embodiment approach 2

[0014] Specific implementation mode two: as figure 1 , figure 2 , image 3 and Figure 4 As shown, the joint detection components 105 - 1 and 105 - 2 include housings 9 , 10 , 11 , a transmission shaft 12 and an angle sensor 13 . The transmission shaft 12 is linked with the angle sensor 13 through gear meshing. Action implementation process: when the transmission shaft 12 rotates, the transmission shaft 12 drives the angle sensor 13 to rotate through the gear.

specific Embodiment approach 3

[0015] Specific implementation mode three: as figure 1 , figure 2 , image 3 and Figure 4 As shown, the upper arm fixing device 102 includes an upper arm fixing ring upper part 4 , an upper arm fixing ring lower part 6 , and a rotating connector 8 . Both ends of the upper arm fixing ring upper part 4 and the upper arm fixing ring lower part 6 are fixedly connected by screws to form a complete ring. The rotating connector 8 and the upper arm fixing ring upper part 4 are hinged to the hole E of the upper arm fixing ring upper part 4 through screws, and the axis of the hinged rotation connecting part 8 and the upper arm fixing ring upper part 4 is perpendicular to the circular ring of the upper arm fixing ring upper part 4 axis. The shoulder detection device 101 includes joint detection components 105-1, 105-2. The base of the joint detection component 105-1 is affixed to the shoulder base 1, the base of the joint detection component 105-2 is fixed to the transmission shaf...

Abstract

The invention relates to a device for detecting human hand shoulder joint movement, in particular to a human hand upper arm abduction and adduction movement detection device, and aims to solve the problem that an existing detection device is complex in system, complicated in structure, large in detection error and difficult to maintain. A link for detecting a human hand shoulder is designed in a brand-new manner, and a unique connecting mode and ingenious joint measuring layout are adopted, so that when an operator uses the device, flexibility of the arm of the operator can be maintained to greatest extent, movement state of shoulder joints can be detected accurately, and joints of a controlled slave hand and corresponding arm joints of the operator can act coordinately to enhance sense of immediacy of virtual reality or remote operation.

Description

technical field [0001] The invention relates to a detection device for detecting the abduction and adduction movement of the human upper arm. Background technique [0002] Due to the development of science and technology, robots are gradually being used in an increasing range. As a reliable and mature robot, teleoperation robots are widely used in various dangerous, complex and inaccessible environments. It uses a very reliable control method, which is directly controlled by the operator's instructions. As the tasks performed by teleoperated robots become more and more complex, people are pursuing reliability and at the same time put forward higher requirements for their flexibility. It is necessary to implement teleoperation on complex manipulators and control multiple joints of the manipulator together. Coordinate movement to achieve specific functions, which requires the use of a human arm joint motion detection device. The human arm joint motion detection device uses th...
