Title:
ZOOM LENS, CAMERA MODULE, ELECTRONIC DEVICE AND FOCUSING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/180033
Kind Code:
A1
Abstract:
A zoom lens (30), comprising a housing (32), a first motor (36), a first lens (381) and a self-locking assembly (40). The first motor (36) is mounted on the inner side of the housing (32). The first lens (381) is mounted to the first motor (36). The first motor (36) is used to drive the first lens (381) to move along the optical axis direction of the zoom lens (30). The self-locking assembly (40) comprises a limiting member (41), a connecting member (44) and a force-applying member (42). The limiting member (41) is located between the first motor (36) and the housing (32). One end of the connecting member (44) is fixed to the housing (32), and the other end thereof is fixed to the limiting member (41), and the force-applying member (42) is connected to the limiting member (41). When the force-applying member (42) does not apply an acting force to the limiting member (41), the limiting member (41) is in contact with the first motor (36), so that a static friction force is formed between the limiting member (41) and the first motor (36). When the force-applying member (42) applies an acting force to the limiting member (41), the limiting member (41) is separated from the first motor (36). During photographing, the zoom lens (30) is not easily affected by external movement or jittering. When the zoom lens (30) is applied to a camera module (100) and an electronic device (1), the photographing performance of the electronic device (1) is good.
