Counterweight assembly, and counterweight mechanism and holder employing same

Abstract

The invention relates to a counterweight assembly, and a counterweight mechanism and a holder employing the same. The holder comprises a support main body (210) and a supporting table (246) connected to the support main body (210), the holder also comprises an installation rod (244) connected to the support main body (210) and the counterweight assembly (50) arranged on the installation rod in an adjustable manner, the supporting table (246) is connected to the installation rod (244), the counterweight assembly (50) comprises a connecting seat (51) connected to the supporting table (246), guiding members (52) arranged on the connecting seat (51), counterweights (58) connected to the guiding member (52), and connecting pieces (59) arranged on the counterweights (58), fixing portions (513) are formed on the connecting seat (51), the guiding members (52) are arranged on the fixing portions (513), the counterweights (58) are connected to the guiding members (52) via the connecting pieces (59), and the counterweights (58) can move along the guiding members (52) to adjust the center of gravity of the holder and the counterweight assembly.

Description

technical field [0001] The invention relates to a counterweight assembly, a counterweight mechanism using the counterweight assembly and a cloud platform. Background technique [0002] In the process of using electronic devices such as video cameras and cameras to shoot with electric pan / tilts, according to different shooting requirements, it is often necessary to use electronic devices equipped with telephoto lenses for shooting. Due to the heavy weight of the telephoto lens itself, when it is mounted on a light electronic device, the center of gravity of the electronic device will be unstable, and it is easy to shake on the gimbal, affecting the shooting quality. In order to solve the above problems, the existing cloud platform has a bearing platform for installing the electronic device and a mounting platform connected to the bearing platform. The bearing platform can be adjusted to move relative to the mounting platform, so that the photographer can The relative positio...

AI Technical Summary

Problems solved by technology

However, the above-mentioned adjustable pan / tilt relies on the photographer to manually adjust the center of gravity of the electronic device, and it is difficult to accurately adjust the relative position of the carrier platform and the installation platform

When the overall weight of the electronic device is heavy and the weight distribution is uneven, due to the limited range of relative position change between the bearing platform and the installation platform, the limitation of the adjustment stroke makes it difficult for the electronic device to maintain a balanced state within the adjustable range. The center of gravity of the device is offset, and its gravity will cause the torque to be applied between the rotating shafts of the gimbal, which will affect the service life of the gimbal

In addition, because the carrying platform is used to carry the electronic device, it carries a relatively heavy weight, so that when the photographer adjusts the position of the carrying platform relative to the installation platform, the operation is laborious and inconvenient.
