Abstract: A driving module configured for driving a teleconverter lens assembly to move up and down with precision includes a mounting base, a driving assembly connected with the mounting base, and an optical grating sensor. The driving assembly includes a linear motor adapted to be fixedly connected with the teleconverter lens assembly and configured to drive the teleconverter lens assembly to move, and an air cylinder configured to support the teleconverter lens assembly. The optical grating sensor is electrically connected with the linear motor and configured to detect and feedback a position of the teleconverter lens assembly driven by the linear motor in real time. A focusing mechanism including the driving module is also disclosed.
