Abstract
The invention discloses an automatic focusing module at least comprising an installation pedestal, an electronically controlled zooming member, and at least one power transmission member. The installation pedestal at least is accommodated with a lens as well as the electronically controlled zooming member is assembled at one end of the installation pedestal. The electronically controlled zooming member and the lens are on a same optical axis. The power transmission member is buried in the installation pedestal as well as is respectively conducted with the electronically controlled zooming member and an external power supply. The electronically controlled zooming member obtains power supply by the power transmission member; and the curved surface of the electronically controlled zooming member is modulated by changing the power supply, so that an objective of automatic focusing is achieved. According to the automatic focusing module in the embodiment of the invention, the module part number is reduced so as to reduce costs; and because injection molding is realized after the power transmission part is buried in the focusing installation pedestal, the manufacturing technology of the module is easy. And moreover, not the whole power transmission member is exposed, so that it can be avoided that the power transmission member is contacted and conducted with other parts.
