Abstract
Description
Technical Field
[0001] The invention relates to the field of tail support mechanisms, and in particular to an electric tail support mechanism for a large-torque self-locking robot. Background Art
[0002] Due to the development of modern intelligence, unmanned automated tracked robots have been widely recognized in the military and civilian fields. Tracked robots are machines with extremely strong obstacle-crossing capabilities and are suitable for operations in various complex terrains. When tracked robots are climbing slopes or stairs, the angle is too large, or the robotic arm is operating and it is easy to overturn. At this time, the tail support can add effective support to the rear of the robot, allowing the robot to complete the task more efficiently.
[0003] At present, there are three forms of mainstream robot arms: swing leg arm form, mechanical arm auxiliary form and fixed tail support form. The three existing forms have obvious advantages and disadvantages. The swing leg arm form is the main form of tracked or wheeled robots. The swing leg arm is installed at the front end or rear end of the tracked robot, or at both the front and rear ends. This form is relatively mature and suitable for various complex terrains. It has outstanding obstacle crossing capabilities. When crossing obstacles, the swing leg arm is unfolded to provide rear support for the robot without taking up extra space. However, it is currently used for small robots. The mechanical arm form mainly assists the robot in crossing obstacles on a flat road. When it is necessary to cross obstacles, the mechanical arm is controlled to support the ground to assist the robot. The fixed tail support form is to add a fixed tail support to the tail of the robot, which plays a role of rear support when the robot climbs slopes and stairs. This type of robot is large in size and difficult to transport. When climbing slopes or stairs, it will limit the climbing angle, thus having certain defects. Summary of the invention
