Problems solved by technology

[0002] Hinge is a very common connection method in the mechanical field. It is mainly used for the movable connection between two parts, so that the two parts can freely rotate relative to each other, so as to realize the unfolding or folding action between the two parts, and the two parts When two or more parts are hinged, a related hinge structure is required. The conventional hinge structure can directly hinge two parts through a rotating shaft, or realize the hinge of two parts through a hinge. It is widely used in folding platforms, The hinge of door leaf, notebook folding connector and other components, but the existing hinge structure is only used for the hinge connection of two components, and it cannot be fixed after unfolding at a certain angle according to the requirements. The two components are easily affected by external forces and cause overlap. Therefore, people have invented the use of top blocks for fixing. The top block fixation makes the overall volume of the hinged structure larger, and the positioning stability is poor. Most of the unfolding or folding actions are manual operations, and the unfolding or folding actions cannot be completed automatically, and the manual control of the unfolding angle control accuracy is low, which cannot meet the existing high hinge connection requirements such as folding platforms for shooting, smart car doors, etc. fine object articulation

Abstract

The invention discloses a movable hinge structure. The movable hinge structure comprises two or more connecting plates and one or more hinge structures, each hinge structure comprises a rotating shaft, a driving assembly, an ejection assembly, a monitoring assembly and a plurality of sleeves, and each sleeve is provided with a first gear structure and a second inner gear ring structure. The invention further discloses an unfolding and folding method. A coil and an annular magnet are arranged to form the driving assembly to control the rotating shaft to rotate and drive a first sleeve to rotate to drive the connecting plate to be unfolded or folded, automatic action is achieved, monitoring of the rotating angle is achieved in cooperation with the monitoring assembly formed by a first magnet and a first Hall sensor, the angle unfolding precision is improved, the first gear structure and a second gear structure are arranged to form a double locking structure, the first gear structure and the second gear structure are optimized and improved to improve fitting precision, press-in interference can be formed to offset fit clearance, deviation is reduced, and stability and supporting performance are improved.
