Problems solved by technology

The bionic joint structure of the existing foreign dummies is complex, and it is difficult to adjust the friction force between the moving parts in the joint. The elbow joint of the American Type III dummy uses a slider to tighten the friction plate to adjust the tightness of the friction plate, so that it is easy to adjust the friction force. The force is eccentric, and the data of the bionic joint structure of foreign dummies is kept confidential

Embodiment 1

[0022] The bionic joint structure of the mannequin includes an upper arm 1, a lower arm 7 and two rotating parts, and has two rotational degrees of freedom, that is, the rotation of the upper arm around the horizontal axis and the rotation of the lower arm relative to the upper arm. The upper arm and the lower arm are flexibly connected, and the upper arm 1 rotates relative to the lower arm 7 around the horizontal axis. The adjusting screw 4 is jointly controlled. When the adjusting screw 4 is twisted clockwise, the friction sliding blocks 2 and 3 press the upper arm inward, and the friction force increases. When the adjusting screw 4 is twisted counterclockwise, the friction sliding block moves outward. Then the friction force is reduced. The connecting screw 9 connects the upper part and the lower part of the lower arm, and the lower part 8 of the lower arm 7 rotates around the axis of the lower arm 7. A friction pad 10 is installed under the connecting screw 9 to adjust the...

Abstract

A bionic joint structure of human body model consists of top arm, bottom arm and two rotation parts. It is featured as actively connecting top arm to bottom arm, rotating top arm around axis line of bottom arm, limiting rotary position by spacing screw and positioning notch, regulation frictional force with sliding block and regulation screw, using connection screw to connect down part with up part of bottom arm to let down part rotate relatively to axis line of bottom arm and using pad and anchoring screw to regulate frictional force and rotation.

Description

1. Technical field [0001] The invention relates to a bionic joint structure of a human body model, belonging to the field of bionic structures of a human body model. 2. Background technology [0002] The research of bionic joint structure is different from the research of robot hand joint. The robot hand designs the kinematic joints mainly from the degree of freedom of motion and the realizability of the motion trajectory, while the design of the bionic joint structure includes the simulation of the range of motion of the human body, the simulation of the range of motion and the limit, and the simulation of friction damping. The technology has not been reported yet (the content in this respect has been searched when applying for the innovation fund of the Ministry of Science and Technology of the People's Republic of China, the 2002 Innovation Fund of the Ministry of Science and Technology of the People's Republic of China, code: 02C26225120242). Foreign human body models s...
