Description

Technical Field

[0001] The invention relates to the technical field of photographic technology, and in particular to a swing arm lever load-bearing support balancing device. Background Art

[0002] Driven by modern technology, cameras have made significant progress, and the camera's rotation function plays a vital role in many scenarios. From industrial visual inspection to panoramic shooting in the consumer electronics field, from security monitoring to film and television production, the demand for multi-angle rotation shooting of cameras is growing.

[0003] In the early camera rotation technology, the motor drive mechanism was mainly used to realize the camera's rotation shooting function, and the motor power device was connected to the rotating target through a bearing to achieve rotational motion. This technical solution has a relatively simple structure and low cost. It meets the basic rotation requirements of the camera to a certain extent and has been widely used in some scenes that do not require high rotation accuracy and stability.

[0004] However, with the continuous expansion of camera application scenarios and the gradual improvement of shooting quality requirements, the limitations of existing camera rotation shooting have become increasingly obvious. For some heavy camera equipment, the solution of using a single bearing connection has serious problems. Due to the influence of the lever effect, the heavier the camera and the larger the rotating arm, the larger the force arm, which will cause most of the force to be concentrated on the bearing. During the rotation of the camera, this unbalanced force situation can easily lead to unsmooth rotation movement or even jamming.

[0005] This unsmooth rotation will not only affect the stability of the camera's images, causing them to shake and blur, reducing the quality of the images, but will also seriously affect the stability and life of the camera's rotation system. Frequent freezes and jams will accelerate the wear of bearings and other components, increase the maintenance cost and replacement frequency of the equipment, and bring a greater financial burden to users. In addition, in application scenarios that require high shooting angle accuracy, such as industrial visual inspection and high-precision panoramic photography, existing technologies cannot guarantee the accuracy of the camera's rotation angle, which affects the accuracy of the inspection results and the integrity of the panoramic photos.

[0006] Therefore, a swing arm lever load-bearing support balancing device is provided to address the deficiencies in the prior art. Summary of the invention
