Title:
ZOOM ASSEMBLY, LENS MODULE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/164406
Kind Code:
A1
Abstract:
A zoom assembly (30), comprising a first refractive element (31) and a first lens device (33). The first refractive element (31) is used to change the transmission path of light, and the first refractive element (31) comprises a first surface (311), a second surface (312), a third surface (313) and a first reflective structure (317). The three surfaces of the first refractive element (31) are all transmission surfaces, and the optical axis of the first lens device (33) is perpendicular to the second surface (312) of the first refractive element (31). The first reflective structure (317) is attached to the third surface (313) and used for receiving light transmitted by one of the transmission surfaces and reflecting the light to another transmission surface. The first refractive element (31) satisfies one or more of the following conditions: the first surface (311) is attached to a focusing lens (L1), the second surface (312) is attached to a focusing lens (L5), and the first reflective structure (317) comprises a focusing lens (M1) and a reflective layer (3173) attached to one side of the focusing lens (M1) away from the third surface (313), which is beneficial to the compact structure of the zoom assembly (30), and effectively reduces the space occupied by the zoom assembly (30). Also provided are a lens module (101) and an electronic device (100).
