PERISCOPIC OPTICAL ZOOM MODULE AND ASSEMBLY METHOD THEREFOR, AND CORRESPONDING ADJUSTABLE OPTICAL ASSEMBLY

Provided is an adjustable optical assembly (900), including a bearing base (921), a driving mechanism (910), a zoom optical assembly (200), and a compensating optical assembly (300). The driving mechanism (910) includes: a bracket (911) having a bottom end connected to the bearing base (921) and a top end having a top groove (911a) open upwards; guide rods (912, 913) supported on the top groove (911a), the guide rods (912, 913) coinciding with the direction of optical axes of the zoom optical assembly (200) and the compensating optical assembly (300); a zoom bearer (914); a compensating bearer (915); a zoom driving assembly; and a compensating driving assembly. The zoom bearer (914) and the compensating bearer (915) are both mounted on the guide rods (912, 913) and slidable along the guide rods (912, 913). Also provided are a corresponding periscopic optical zoom module and an assembly method therefor. According to the adjustable optical assembly (900), the bracket (911) and the guide rods (912, 913) are disposed on the bearing base (921), thereby effectively ensuring that the moving directions of a zoom group and a compensating group do not deviate from a main optical axis. Moreover, the adjustable optical assembly (900) is compact in structure and convenient to assemble, and facilitates large-scale mass production.
