Problems solved by technology

However, doing so is time consuming and still results in substantial debris formation
Camera modules are often discarded due to contamination
Therefore, camera modules with threaded focusing have a relatively high production loss

Abstract

The invention discloses a camera module with threadless lens barrel engagement design, possessing a lens barrel, a lens and a lens carrier that slidably receives the lens barrel. Each of the exterior surface of the lens barrel and the interior surface of the lens carrier include a seating surface formed thereon. One of the exterior surface of the lens barrel and the interior surface of the lens carrier include a plurality of protrusions for controlling the relative position of the lens barrel and the lens carrier. The other of the exterior surface of the lens barrel and the interior surface of the lens carrier include a plurality of channels that are sized and arranged so as to slidably receive the protrusions to allow for the lens barrel to be slid into the lens carrier. The channels also each include a transverse section to allow the lens barrel to be pivoted about an optical axis of the lens barrel.

Description

technical field [0001] The present disclosure relates generally to electronic devices, and more particularly to digital camera modules. More particularly, it relates to a digital camera module design to prevent or minimize contamination of a sensor array of an image capture device by debris and particulate matter generated by the focusing process. Background technique [0002] Currently, digital camera modules are incorporated into various electronic devices. Such hosts containing camera modules include, but are not limited to: cell phones, personal data assistants (PDAs), and computers. As the ability to add camera modules to the mainframe has expanded, so has the demand for digital camera modules. Therefore, one design goal of digital camera modules is to make them as small as possible so that they can be embedded in electronic devices without significantly increasing the size of the overall device. Of course, the method to achieve this goal must guarantee the quality o...
