PRESSING RING AND CAMERA LENS MODULE
The present disclosure provides a pressing ring. The pressing ring includes: an annular body forming a light through hole; and a shearing edge formed on the annular body. The body includes an inner side wall around an optical axis and forming the light through hole, an abutting wall extending from an edge of the inner side wall close to an object side in a direction facing away from the optical axis, and an outer side wall extending from an edge of the abutting wall facing away from the inner side wall along a direction of the optical axis and provided opposite to the inner side wall. The abutting wall includes an abutting surface surrounding the inner side wall and connected to the inner side wall, and a glue-dispensing groove surrounding the abutting surface and connected to the abutting surface; the shearing edge being located in the glue-dispensing groove.
1 . A pressing ring, comprising:
an annular body forming a light through hole; and
a shearing edge formed on the annular body,
wherein the body comprises an inner side wall around an optical axis and forming the light through hole, an abutting wall extending from an edge of the inner side wall close to an object side in a direction facing away from the optical axis, and an outer side wall extending from an edge of the abutting wall facing away from the inner side wall along a direction of the optical axis and provided opposite to the inner side wall,
the abutting wall comprises an abutting surface surrounding the inner side wall and connected to the inner side wall, and a glue-dispensing groove surrounding the abutting surface and connected to the abutting surface; the shearing edge being located in the glue-dispensing groove.
2 . The pressing ring as described in claim 1 , wherein the glue-dispensing groove comprises a first side surface extending from an edge of the abutting wall facing away from the optical axis along a direction of the optical axis, and a second side surface extending from an edge of the first side surface facing away from the abutting wall in a direction facing away from the optical axis; the shearing edge being located at the second side surface.
3 . The pressing ring as described in claim 2 , wherein the outer side wall comprises a first side wall extending from an edge of the second side surface facing away from the optical axis in a direction facing towards an image side and facing away from the optical axis, a second side wall extending from an edge of the first side wall facing away from the second side surface in a direction facing away from the optical axis, and a third side wall extending from an edge of the second side wall facing away from the first side wall towards the image side along the direction of the optical axis.
4 . The pressing ring as described in claim 1 , wherein the inner side wall comprises a first surface extending from an edge of the abutting surface close to the optical axis in a direction facing away from the object side and facing towards the optical axis, and a second surface extending from an edge of the first surface facing away from the abutting surface in a direction facing towards the image side and facing away from the optical axis.
5 . A camera lens module, comprising the pressing ring as described in claim 1 .
6 . A camera lens module, comprising the pressing ring as described in claim 2 .
7 . The camera lens module as described in claim 5 , wherein the inner side wall comprises a first surface extending from an edge of the abutting surface close to the optical axis in a direction facing away from the object side and facing towards the optical axis, and a second surface extending from an edge of the first surface facing away from the abutting surface in a direction facing towards the image side and facing away from the optical axis.
8 . The camera lens module as described in claim 6 , wherein the outer side wall comprises a first side wall extending from an edge of the second side surface facing away from the optical axis in a direction facing towards an image side and facing away from the optical axis, a second side wall extending from an edge of the first side wall facing away from the second side surface in a direction facing away from the optical axis, and a third side wall extending from an edge of the second side wall facing away from the first side wall towards the image side along the direction of the optical axis.
