Lens module with a pressure-proof part with at least one notch penetrating a top wall and communicating with a receiving space
The present disclosure relates to the technical field of optical lenses and discloses a lens module. The lens module includes: a lens; a lens barrel receiving the lens; a lens seat receiving the lens barrel; and a pressure-proof part having a receiving space. The lens barrel is installed into the lens seat from an object side of the lens seat to form an imaging body. The pressure-proof part includes a top wall forming a through hole and disposed at an object side of the lens barrel and a side wall extending from an edge of the top wall facing away from an optical axis while being bent towards an image side, the top wall and the side wall forming the receiving space. The receiving space receives at least a portion of the imaging body.
1. A lens module, comprising:
a lens;
a lens barrel receiving the lens;
a lens seat receiving the lens barrel; and
a pressure-proof part having a receiving space,
wherein the lens barrel is installed into the lens seat from an object side of the lens seat to form an imaging body; the pressure-proof part comprises a top wall forming a through hole and disposed at an object side of the lens barrel and a side wall extending from an edge of the top wall facing away from an optical axis while being bent towards an image side, the top wall and the side wall forming the receiving space; and the receiving space receives at least a portion of the imaging body, and the pressure-proof part is provided with at least one notch penetrating the top wall and communicating with the receiving space.
2. The lens module as described in claim 1 , wherein the side wall and the lens seat are provided with threads, and the lens seat is fixed to the side wall by fitting the threads.
3. The lens module as described in claim 1 , wherein the at least one notch is spaced from an outer edge of the top wall.
4. The lens module as described in claim 1 , wherein the at least one notch reaches an outer edge of the top wall, and the at least one notch penetrates the side wall.
5. The lens module as described in claim 3 , wherein the at least one notch comprises at east two notches.
6. The lens module as described in claim 4 , wherein the at least one notch comprises at least two notches.
7. The lens module as described in claim 5 , wherein the at least two notches are equally spaced around the optical axis.
8. The lens module as described in claim 6 , wherein the at least two notches are equally spaced around the optical axis.
9. The lens module as described in claim 7 , wherein each of the at least two notches has an arc shape about the optical axis of the lens barrel, and the arc shape corresponds to a central angle that is larger than 0° and smaller than 90°.
10. The lens module as described in claim 8 , wherein each of the at least two notches has an arc shape about the optical axis of the lens barrel, and the arc shape corresponds to a central angle that is larger than 0° and smaller than 90°.
11. The lens module as described in claim 1 , wherein the lens seat and the lens barrel are formed into one piece.
