Title:
ROTARY JOINT AND ANTI-COLLISION METHOD OF ROTARY JOINT
Document Type and Number:
WIPO Patent Application WO/2020/252858
Kind Code:
A1
Abstract:
A rotary joint, comprising: a first joint structure (1) provided with a first limiting structure (11); a second joint structure (2) rotatably connected to the first joint structure (1) and provided with a second limiting structure (21) that cooperates with the first limiting structure (11) so as to limit the maximum rotation angle of the second joint structure (2) relative to the first joint structure (1); a driving unit (3) connected to the second joint structure (2) and used for driving the second joint structure (2) to rotate relative to the first joint structure (1); and a damping adjustment unit that controls the driving unit (3) to output a first torque that is opposite to the rotation direction of the second joint structure (2) when the second joint structure (2) rotates to a predetermined position relative to the first joint structure (1). Also disclosed is an anti-collision method of the rotary joint, so as to avoid rigid collision from occurring between the first limiting structure and the second limiting structure.
