Transmission components for the vertical movement of the gimbal

Abstract

The invention discloses a transmission assembly of which a cradle head moves in the vertical direction. The transmission assembly comprises motors, a motor mounting rack, a transmission shaft, a cradle head seat and a fixed base, wherein the motors are fixedly mounted on the motor mounting rack; the motor mounting rack is connected with the cradle head seat; the transmission shaft is movably connected with the motor mounting rack; a first transmission component is arranged between motor shafts and the transmission shaft; a second transmission component is arranged between the transmission shaft and the fixed base; and the first transmission component comprises the motor shafts and the transmission shaft which are connected through cooperation of a worm gear and a worm. In the transmission assembly, the motors can drive the cradle head to rotate with relatively low power, so that the requirement on the motors is reduced, and the overall power consumption is reduced; under the outage condition, the worm gear and the worm which cooperate with each other have relatively large self-locking torque, and the cradle head seat is prevented from freely falling; and besides, a return part can counteract torque generated by gravity of all parts on the cradle head seat, so that the motors with relatively low power can be adopted to drive the cradle head seat to rotate in the vertical direction.

Description

technical field [0001] The invention relates to the technical field of video surveillance equipment, in particular to a transmission assembly for the vertical movement of a pan-tilt. Background technique [0002] The pan / tilt is a supporting device for installing and fixing the camera, and it is divided into two types: fixed and electric pan / tilt. The fixed pan / tilt is suitable for the situation where the monitoring range is not large. After installing the camera on the fixed pan / tilt, you can adjust the horizontal and pitch angles of the camera. After reaching the best working posture, you only need to lock the adjustment mechanism; the electric pan / tilt is suitable For scanning and monitoring a large area, it can expand the monitoring range of the camera. The positioning drive of the electric pan / tilt is realized by the motor. The motor receives the signal from the controller to run and position accurately, and automatically adjusts the camera's position in the horizontal ...

Problems solved by technology

But, because in the cloud platform of prior art, structures such as camera 7, lamp board and wiper are all installed in the front end of platform base, cause the center of gravity of cloud platform to be forward, produce bigger moment with respect to transmission shaft, motor needs to have bigger power Only then can the torque generated by gravity be able to offset the rotation of the camera, which increases the power consumption of the whole machine and increases the heat generated by the device. When the motor is powered off, the motor cannot continue to provide upward holding torque, which will cause the gimbal base to drive the camera freely. sagging
