Abstract

The invention discloses a mechanism for compensating gravitational torque generated by a vertical rotary component and relates to the technical field of video terminal equipment. The mechanism is composed of a main shaft, a crankshaft and a power-assisted part. One end of the crankshaft is vertically connected with one end of the main shaft, and the other end of the crankshaft is hinged to the power-assisted part. The mechanism can generate varying elastic force. Elastic torque for the output shaft of a motor is generated by the elastic force and can balance gravitational torque for the main shaft of the motor, wherein the gravitational torque is generated because the direction where the vertical rotary component bears gravity is not on the same straight line with the direction of the main shaft of the motor, and the varying range of the elastic torque is large, so that problems that the service life of the motor is reduced due to gravitational torque, and the drive control circuit of video terminal equipment is complicated are effectively solved.

Description

technical field [0001] The present invention relates to the technical field of video terminal equipment, in particular to a mechanism for compensating the gravitational moment generated by a vertically rotating component applied to the video terminal equipment. Background technique [0002] In the surveillance industry, video terminal equipment is the main equipment for collecting visual signals. Video terminal equipment mainly includes dome cameras (dome cameras), bullet cameras (gun cameras), dome cameras, and PTZ cameras. Since it is difficult to balance the center of gravity of the vertically rotating parts in the video terminal equipment, the moment of gravity changes during the vertical rotation of the vertically rotating parts, and even has a large difference, so the torque of the motor and the drive control circuit of the device Make higher demands. At present, methods such as increasing the torque of the motor and adding counterweights are used in the equipment in ...
