取像镜头后焦调整结构
摘要：
本发明提供一种取像镜头后焦调整结构，其包括一个镜头模块、一个前盖、一个调焦装置以及一个驱动装置。所述镜头模块具有一个镜头以及一个影像传感器，所述镜头设置于所述前盖的前端，所述前盖内以导杆支撑设置所述调焦装置，所述调焦装置具有一个基座，所述影像传感器设置于所述基座上并与所述镜头相对，所述驱动装置具有一个马达以及一个导螺杆，所述马达驱动所述导螺杆，所述导螺杆驱使所述基座位移调整所述影像传感器的位置。本发明通过以导螺杆的连接驱动，使所述影像传感器后焦调整位移稳定，可以提高取像的质量。
摘要（英）：

The invention provides an image capture lens rear focus adjusting structure. The structure comprises a lens module, a front cover, a focusing apparatus and a driving apparatus. The lens module possesses a lens and an image sensor. The lens is arranged on a front end of the front cover. In the front cover, a guide rod is used to support and set the focusing apparatus. The focusing apparatus possesses a pedestal. The image sensor is arranged on the pedestal and is opposite to a lens. The driving apparatus possesses a motor and a driving screw. The motor drives the driving screw. The driving screw impels the pedestal to carry out displacement adjustment on a position of the image sensor. According to the structure of the invention, through connection driving of the driving screw, a rear focus adjusting displacement of the image sensor is stable and image capture quality can be increased.
