Title:
LENS MODULE
Document Type and Number:
WIPO Patent Application WO/2021/000160
Kind Code:
A1
Abstract:
A lens module (100), comprising: a base (1); a lens base (2) provided with a lens and fixed in the base (1); a circuit board (3) for providing an electrical signal; a support component (4) for supporting the lens base (2); and a shape-memory alloy wire (5) for driving the lens base (2) to move in a direction perpendicular to the optical axis of the lens. The lens base (2) is suspended in the base (1) by means of the support component (4). The shape-memory alloy wire (5) comprises a tail end (51) and a drive end (52). The drive end (52) is connected to the lens base (2). The lens module (100) further comprises a conductive element (6). The conductive element (6) comprises a fixed portion (61) fixed onto the base (1), a connection portion (62) located at a side of the fixed portion (61) and connected to the tail end (51) of the shape-memory alloy wire (5), a terminal (63) located at another side of the fixed portion (61) and electrically connected to the circuit board (3), and several bending portions (64) connected between the fixed portion (61) and the terminal (63). An included angle α is formed between the terminal (63) and the fixed portion (61), and is greater than 90 degrees. The configuration ensures that the conductive element (6) is stably welded to the circuit board (3), reduces the height of the conductive element (6) in the direction of the optical axis, and reduces the height of the lens module (100).
