Abstract

The invention discloses a torque protection device of an electric guide plate. The torque protection device comprises a rotating sleeve, an inner backing plate, an outer backing plate, a pressing plate, a bull gear, friction plates and spring parts. The rotating sleeve is connected with a transmission shaft, and is used for transmission; the inner backing plate and the pressing plate are connected to the rotating sleeve, and rotate with the rotating sleeve; the outer backing plate is connected to the bull gear, and rotates with the bull gear; the friction plates are arranged among all the fitting surfaces of the rotating sleeve, the inner backing plate, the outer backing plate, the pressing plate and the bull gear, so that torque transmission is performed among the fitting surfaces by frictional force. The spring pats are used for pressing the bull gear, the inner backing plate, the pressing plate, and the outer backing plate against the rotating sleeve firmly, and the spring parts are locked on the rotating sleeve. When the torque protection device of the electric guide plate is subjected to external impact force, and the impact force exceeds a friction torque threshold of the friction plates, the fitting surfaces will slide relatively to release the impact force. An internal friction fitting position is employed to release overloaded impact force, so that a problem of conventional electric guide is solved, wherein the problem is that parts are damaged because of hard transmission performed directly through a gear mechanism.
