Simplified rotating module

Abstract

The invention relates to a simplified rotating module, and the module is characterized by comprising a housing, a bearing seat used for bearing the light path adjusting assembly, a base used for containing and supporting the bearing seat, a supporting assembly arranged between the bearing seat and the base and meeting and limiting the bearing seat to rotate around the first rotating shaft and the second rotating shaft respectively, a clamping assembly arranged between the bearing seat and the base and providing a clamping force to enable the bearing seat, the base and the supporting assembly to keep stable contact, a driving assembly used for generating driving force to enable the bearing seat to rotate around the first rotating shaft or the second rotating shaft, and a sensing assembly adopting an electromagnetic sensing assembly or an optical sensing assembly and used for measuring the rotating angles of the bearing seat on the first rotating shaft and the second rotating shaft. According to the invention, the rotating fulcrum and the arc-shaped track are matched with the clamping force, so that the two-axis rotation of one bearing seat can be realized without the assistance of additional suites, the requirement on the angle adjustment of the light path is further met, and the closed-loop control of the light path adjustment is realized by matching with the driving assembly and the sensing assembly.

Description

technical field [0001] The invention relates to a simplified rotating module, which is suitable for mounting an optical refraction module, and can also be extended to mount an optical lens or other optical components. Background technique [0002] Generally speaking, most of the voice coil motors on the market move in a straight line. Whether it is the focus motor (AF) or the anti-shake system motor (OIS), most of them are used to carry optical components for translation to achieve the required optical effect. Limited by the volume and height requirements of digital products on the market, linear optical path products need to be turned to reduce the size of the original equipment or components, that is, the turning of the optical axis is realized through the principle of refraction, thereby reducing the size of the initial equipment or components . In this case, the translational movement of the optical component may not be able to meet the optical path adjustment or applic...

Problems solved by technology

However, the use of two sets of kits has the following problems: 1. The kits take up a large volume, which leads to difficulties in stack design; 2. It is difficult to import electrical signals into multiple kits, and the sensing of the inner kit is easily interfered by the rotation of the outer kit, resulting in signal crosstalk. ; 3. There are many parts in multiple kits and the cost is high, and the assembly process is complicated
