Abstract

A lens limiting assembly includes an elastic element including an annular elastic body and an elastic arm extending from an inner side of the elastic body inward and downward along an axial direction, and a locking ring including a flange configured to abut against the elastic arm.

First claim

What is claimed is:

1. A lens limiting assembly comprising:
an elastic element including an annular elastic body and an elastic arm extending from an inner side of the elastic body inward and downward along an axial direction; and
a locking ring including a flange configured to abut against the elastic arm.

2. The lens limiting assembly of claim 1 , wherein the elastic arm includes a first end connected to the elastic body and a second end extending away from the elastic body, the second end being spaced apart from the elastic body along the axial direction.

3. The lens limiting assembly of claim 2 , wherein the flange is configured to be accommodated in a gap formed between the elastic arm and the elastic body.

4. The lens limiting assembly of claim 1 , further comprising:
a lens assembly ring arranged on the elastic element.

5. The lens limiting assembly of claim 4 , wherein the locking ring is arranged outside the lens assembly ring.

6. The lens limiting assembly of claim 4 , wherein the flange is configured to press the elastic arm when the locking ring rotates in one direction.

7. The lens limiting assembly of claim 4 , wherein the flange is configured to be positioned between the lens assembly ring and the elastic arm.

8. The lens limiting assembly of claim 4 , wherein the lens assembly ring includes a limiting part, such that when a lens is rotatably assembled into the lens assembly ring, a snapping body of the lens is held below the limiting part and the elastic element.

9. The lens limiting assembly of claim 4 , wherein:
the lens assembly ring includes a receiving groove; and
the locking ring includes:
a body; and
a hook protruding inwardly from the body and accommodated in the receiving groove, the hook including:
a connecting part connected to an inner wall of the body; and
a bent part, one end of the bent part being connected to the connecting part, another end of the bent part extending straightly, and the flange being formed at a tail end of the bent part and extending toward the elastic arm.

10. A camera body comprising:
a fixing frame having a contact base mounting position; and
a lens limiting assembly mounted on the contact base mounting position and including:
an elastic element including an annular elastic body and an elastic arm extending from an inner side of the elastic body inward and downward along an axial direction; and
a locking ring including a flange configured to abut against the elastic arm.

11. The camera body of claim 10 , wherein the lens limiting assembly further includes a lens assembly ring arranged on the elastic element.

12. A camera comprising:
a lens;
a camera body configured to receive the lens; and
a lens limiting assembly arranged on the camera body and including:
an elastic element including an annular elastic body and an elastic arm extending from an inner side of the elastic body inward and downward along an axial direction; and
a locking ring including a flange configured to abut against the elastic arm.

13. The camera of claim 12 , wherein the elastic arm includes a first end connected to the elastic body and a second end extending away from the elastic body, the second end being spaced apart from the elastic body along the axial direction.

14. The camera of claim 13 , wherein the flange is configured to be accommodated in a gap formed between the elastic arm and the elastic body.

15. The camera of claim 12 , wherein the lens limiting assembly further includes a lens assembly ring arranged on the elastic element.

16. The camera of claim 15 , wherein the locking ring is arranged outside the lens assembly ring.

17. The camera of claim 15 , wherein the flange is configured to press the elastic arm when the locking ring rotates in one direction.

18. The camera of claim 15 , wherein the flange is configured to be positioned between the lens assembly ring and the elastic arm.

19. The camera of claim 15 , wherein:
the lens includes a snapping body provided on an outer side of the lens; and
the lens assembly ring includes a limiting part, such that when the lens is rotatably assembled into the lens assembly ring, the snapping body of the lens is held below the limiting part and the elastic element.

20. The camera of claim 15 , wherein:
the lens assembly ring includes a receiving groove; and
the locking ring includes:
a body; and
a hook protruding inwardly from the body and accommodated in the receiving groove, the hook including:
a connecting part connected to an inner wall of the body; and
a bent part, one end of the bent part being connected to the connecting part, another end of the bent part extending straightly, and the flange being formed at a tail end of the bent part and extending toward the elastic arm.
