Embodiment Construction

[0028] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0029] Such as figure 1 The shown mechanism for compensating the gravitational moment generated by the vertically rotating parts includes: a crankshaft 1 , a booster part 2 , a static support shaft 3 and a main shaft 4 . The crankshaft 1 includes a first crank arm 101 and a connecting rod journal 102 , the end of the first crank arm 101 away from the connecting rod journal 102 is vertically connected to one end of the main shaft 4 in an L shape. Such as figure 1 with image 3 As shown, the first crank arm 101 and the connecting rod journal 102 are vertically connected in an L shape. One end of the booster component 2 is hinged to the connecting rod journal 102, and the other end is hinged to the static support shaft.

[0030] Such as image 3 As shown, the crankshaft 1 further includes a second...

Abstract

The invention discloses a mechanism for compensating the gravitational moment generated by a vertically rotating part, which relates to the technical field of video terminal equipment and is composed of a main shaft, a crankshaft and a booster component. One end of the crankshaft is vertically connected to one end of the main shaft, and the other end is connected to the booster The parts are hinged, the invention can produce a variable elastic force, and the elastic moment produced by this elastic force on the output shaft of the motor can balance the weight on the motor shaft caused by the vertically rotating parts because the direction of gravity and the direction of the motor shaft are not on the same straight line. Torque, the change range of this elastic moment is relatively large, which can effectively solve the problems of reduced service life of the motor caused by gravity moment and complicated drive control circuit of video terminal equipment.

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 ...
