Leg and foot elastic device of a legged robot

Abstract

The invention discloses a leg and foot elastic device of a legged robot, comprising a first foot plate and a second foot plate, the center of the top of the first foot plate is fixedly connected with the lower end of a connecting rod, and the first foot plate There is an inner cavity inside, and a movable plate is placed inside the inner cavity, a through groove is reserved at the bottom of the inner cavity, and a connecting plate runs through the inside of the through groove, and the top of the connecting plate is fixedly connected to the bottom of the movable plate. At the center, the bottom of the connecting plate is fixedly connected with a second foot plate, and the bottom of the second foot plate is provided with a rubber anti-skid block; the present invention is provided with a first spring, shock absorbing rubber, a second spring and a third spring , to ensure that the robot has a four-fold buffer effect when walking, thus playing a good role in protecting the precision parts inside the robot and prolonging the service life of the robot.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a leg and foot elastic device of a legged robot. Background technique [0002] Robot is a common name for automatic control machines. Automatic control machines include all machinery that simulates human behavior or thinking and simulates other creatures, such as robot dogs, robot cats, etc., and the legs and feet at the bottom of the robot are used for support and walking. [0003] For example, a kind of intelligent rehabilitation robot disclosed by the invention whose publication number is CN206910495U, although it can help to record the patient's walking situation and has the advantage of being convenient to use, the foot plate at the bottom of the robot is not provided with an elastic device, which causes the robot to walk. , cannot play the role of cushioning, which will easily cause damage to the precision parts inside the robot and reduce the service life of the...
