Title:
AUTOMATIC FOCUSING LENS ASSEMBLY AND AUTOMATIC FOCUSING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/243859
Kind Code:
A1
Abstract:
An automatic focusing lens assembly (100) and an automatic focusing method thereof. The automatic focusing lens assembly (100) comprises a lens (11), a first base (12), a second base (13), a pair of elastic components (14, 15), and a pair of memory alloy wires (16, 17). The second base (13) comprises a first base body (133) and a second base body (134) that are arranged at intervals along the direction of an optical axis (S); the lens (11) is slidably mounted on the second base body (134) along with the first base body (12); the first base body (12) comprises an extension arm (12a) extending between the first base body (133) and the second base body (134); the two ends of each elastic component (14, 15) are respectively connected with the first base (12) and the first base body (133); the two memory alloy wires (16, 17) are respectively provided at the two sides of the lens (11); each memory alloy wire (16, 17) comprises a fixed portion (161, 171) fixed to the second base body (134), a first connection portion (162, 172) extending from the first fixed portion (161, 171) towards the extension arm (12a), a second fixed portion (163, 173) fixed to the extension arm (12a), a second connection portion (164, 174) extending from the second fixed portion (163, 173) towards the second base body (134), and a third fixed portion (165, 175) connected with the second connection portion (164, 174) and fixed to the second base body (134). The automatic focusing lens assembly (100) has the advantage of being capable of realizing miniaturization design.
