Title:
PERISCOPIC PHOTOGRAPHING MODULE AND VARIABLE-FOCUS PHOTOGRAPHING MODULE
Document Type and Number:
WIPO Patent Application WO/2022/214084
Kind Code:
A1
Abstract:
A periscopic photographing module and a variable-focus photographing module. For some drive mechanisms (742, 743, 842, 843, 942, 943) in the periscopic photographing module and the variable-focus photographing module, piezoelectric actuators (7100, 8100, 9100) are used as drivers to provide sufficient driving force and a better driving performance. The piezoelectric actuator (7100) comprises a piezoelectric active portion (7110), a driven shaft (7120) connected to the piezoelectric active portion (7110) in a transmission manner, and a drive portion (7130) movably arranged on the driven shaft. Alternatively, the piezoelectric actuator (8100) comprises a piezoelectric active portion (8110), and a friction drive portion (8120) connected to the piezoelectric active portion (8110) in a transmission manner. Alternatively, the piezoelectric actuator (9100) comprises an actuating system (9110) and a drive circuit system (9120), wherein the actuating system comprises a piezoelectric plate structure (9111) and a friction drive portion (9112) fixed to the piezoelectric plate structure (9111), and the actuating system (9110) is controlled by the drive circuit system (9120) to move in a preset direction, along a two-dimensional trajectory, in the manner of flexural vibration in two directions.
