Abstract

The invention discloses an electric rotating locating device used for a camera polarized lens. The electric rotating locating device used for the camera polarized lens comprises a polarized lens, a polarized lens gear, a driving mechanism, a control mechanism of the polarized lens gear, a supporting mechanism of the polarized lens gear and a substrate. The driving mechanism, the control mechanism of the polarized lens gear, and the supporting mechanism of the polarized lens gear are arranged on the substrate. The polarized lens gear is a hollow ring gear. The polarized lens is embedded in the polarized lens gear which is driven by the driving mechanism to rotate. The supporting mechanism of the polarized lens is meshed with the polarized lens gear and used for supporting the polarized lens gear in a suspension mode. The control mechanism of the polarized lens gear is capable of detecting and sensing a rotating location and a rotating angle of the polarized lens gear, issuing pulse command to the driving mechanism, and controlling movement of the driving mechanism. Therefore, the polarized lens gear is driven to rotate to a set rotation angle. The electric rotating locating device used for the camera polarized lens is capable of controlling rotation remotely and locating accurately the polarized lens.

Description

technical field [0001] The invention relates to a camera component, in particular to an electronically controlled rotary positioning device for a camera polarized lens. Background technique [0002] At present, surveillance cameras select and filter light from a certain direction by manually rotating the polarizing lens on the lens. When the surveillance camera is installed in a waterproof box or installed in a high place or far away, manual rotation becomes difficult. . At the same time, we also have problems describing the rotation angle of the polarizer. For example, we often say that if you rotate it 30 degrees to the right, the result will be: 30 degrees vertically to the right, 30 degrees upward horizontally, and 30 degrees downward horizontally, etc. Multiple understandings. How to control the rotation of the polarized lens and precisely position the polarized lens has become a difficult technical problem in camera components. Contents of the invention [0003] T...
