Imaging camera
The present application discloses an imaging camera, including: a lens holder with an accommodation space; a lens unit group received in the accommodation space; and a supporting frame. The supporting frame includes a top wall having a first surface facing an object side of the imaging camera, a second surface opposite to the first surface, and a third surface connecting the first surface to the second surface. The imaging camera further includes an aperture formed in the third surface; a glue-in opening formed in the first surface; and a glue-out opening formed in the third surface and communicated with the glue-in opening. By virtue of the invention, the pressing ring can be affixed to the lens holder by the glue flowing from the glue-in opening to the glue-out opening via the first and second channels.
1. An imaging camera, including:
a lens holder with an accommodation space;
a lens unit group received in the accommodation space;
a supporting frame locating at an image side end of the lens holder including
a top wall comprising a first surface facing an object side of the imaging camera, a second surface opposite to the first surface, and a third surface connecting the first surface to the second surface;
an aperture formed in the third surface;
a glue-in opening formed in the first surface and spaced apart from the aperture;
a projection of the lens holder on the first surface spaced apart from the glue-in opening; the lens holder locating on the side of the glue-in opening near an optical axis;
a glue-out opening formed in the third surface and communicated with the glue-in opening for forming a flowing channel.
2. The imaging camera as described in claim 1 , wherein the supporting frame is integral with the lens holder.
3. The imaging camera as described in claim 1 , wherein the supporting frame includes a first channel perpendicularly extending downwardly from the glue-in opening and a second channel communicating with the glue-out opening; the first channel and the second channel form a flow channel connecting the glue-in opening and the glue-out opening.
4. The imaging camera as described in claim 3 , wherein the third surface includes a first part, a second part extending obliquely from the first part toward the object side of the imaging camera, and a third part extending perpendicularly from the second part toward the object side; the glue-out opening is formed in the second part.
5. The imaging camera as described in claim 4 , wherein the lens unit group includes a pressing ring abutting against the lens holder.
6. The imaging camera as described in claim 4 , wherein the lens unit group includes, in an order from an object side of the imaging camera to an image side, a first lens unit, a first shielding, a second lens unit, a second shielding, a third lens unit, a third shielding, a blocking board, a fourth shielding, a fourth lens unit, and a pressing ring.
7. The imaging camera as described in claim 5 , wherein the glue-out opening is corresponding to the pressing ring.
8. The imaging camera as described in claim 6 , wherein the glue-out opening is located adjacent to a joint of the fourth lens unit and the pressing ring.
