Title:
BEAM SCANNING DEVICE FOR ROTATING MIRROR ARRAY
Document Type and Number:
WIPO Patent Application WO/2019/109901
Kind Code:
A2
Abstract:
Disclosed in the present application is a beam scanning device for a rotating mirror array, comprising a motor (1), a screw rod (2), worm gears (3), a mounting frame (4), and rotating mirrors (5). The screw rod (2) and worm gears (3) are arranged upon the mounting frame (4) and are meshedly engaged with each other by means of gear rings (11) so as to move in concert. The rotating mirrors (5) are positioned inside the mounting frame (4) and are coaxially connected to the worm gears (3). The motor (1) is used for driving the screw rod (2), so as further to drive coaxial rotation of the worm gears (3) and the rotating mirrors (5). Rotating mirrors (5) having different structural and optical parameters may be utilized so as to adjust the performance and output of the beam scanning device, thus enhancing extensibility and reducing and resolving problems of bulkiness, high rotational inertia, and high power consumption in traditional beam scanning devices, while also significantly improving system space utilization rates and stability, and being adapted to utilization in LIDAR applications of driverless vehicles and intelligent robots.
