Document Type and Number:
WIPO Patent Application WO/2021/047605
Kind Code:
A1
Abstract:
Disclosed is a lens module, comprising an auto-focus assembly (10), an optical anti-shake assembly (20), an elastic supporting assembly (30) connecting the auto-focus assembly (10) and the optical anti-shake assembly (20), and a driving device (40) for driving the motion of the optical anti-shake assembly (20), wherein the auto-focus assembly (10) is provided with two first side walls (13), which are arranged opposite each other, and two second side walls (14) connected between the two first side walls (13); the driving device (40) comprises two bond clips (42) provided on outer sides of the first side walls (13) and outer sides of the second side walls (14), and a shape memory alloy wire (41) provided between the two bond clips (42); each of the bond clips (42) comprises a first conductive plate (421) arranged on the optical anti-shake assembly (20), and a second conductive plate (422) bending and extending from the first conductive plate (421); the shape memory alloy wire (41) comprises terminal ends (411) respectively connected to the second conductive plates (422) of the two adjacent bond clips (42), and a driving end (412) located between the two terminal ends (411); and the driving end (412) is fitted and connected to the junction of the adjacent first side wall (13) and second side wall (14). The second conductive plates (422) are arranged in a manner of bending at the first conductive plates (421), which can reduce the size of the lens module in the horizontal direction.
