The camera device 200 includes a lens 50 and a mounting assembly 100, the lens 50 being disposed within the mounting assembly 100, the mounting assembly 100 being configured to support and shield the lens 50.

The mounting assembly 100 generally includes a base 10, a position-limiting cover 20, a chassis 30 and an outer cover 40, wherein the position-limiting cover 20 is connected with the base 10 to form a space for accommodating the lens 50, the chassis 30 is disposed on a side of the base 10 away from the position-limiting cover 20, and the outer cover 40 is connected with the chassis 30 to cover the base 10 and the position-limiting cover 20, so as to provide physical protection for the lens 50 therein.

As shown in fig. 3, the base 10 is provided with a hollow portion 12 and a plurality of elastic arms 14 circumferentially arranged along the circumferential side of the hollow portion 12, the elastic arms 14 extend toward the center of the hollow portion 12, the hollow portion 12 can be penetrated by the lens 50, and the plurality of elastic arms 14 are used for supporting the lens 50 together to provide uniform elastic support for the lens 50.

When the lens 50 is forced to move towards the inner side of the hollow part 12, the plurality of elastic arms 14 elastically deform towards the inner side of the hollow part 12 to provide buffering protection for the lens 50, so as to protect the lens 50 from being damaged by external force; the lens 50 is further capable of passing through the hollow portion 12 when the lens 50 is subjected to a force exceeding a preset threshold, thereby providing a higher limit of cushioning protection to the lens 50. The lens 50 referred to herein passes through the hollow portion 12 at the maximum dimension of the lens 50 passing through the hollow portion 12. After the lens 50 passes through the hollow portion 12 at its maximum size, the lens 50 can be significantly pulled away from the object to which the force is applied, so as to be effectively protected and protected from damage.

In other words, when the lens 50 is supported by the plurality of elastic arms 14, three states can exist, specifically: in the first state, the external force applied to the lens 50 is substantially negligible, and the plurality of elastic arms 14 have almost no significant elastic deformation; in the second state, the external force applied to the lens 50 does not exceed the preset threshold, the elastic arms 14 are obviously elastically deformed, but the lens 50 does not pass through the hollow portion 12; in the third state, the external force applied to the lens 50 exceeds the predetermined threshold, the elastic arms 14 are significantly elastically deformed, and the lens 50 passes through the hollow portion 12.

In the present application, the plurality of elastic arms 14 are used to jointly support the lens 50, so that the lens 50 cannot directly pass through the space surrounded by the plurality of elastic arms 14 without elastically deforming the elastic arms 14; the hollow portion 12 is capable of passing the lens 50 therethrough, in other words, the lens 50 presses the plurality of elastic arms 14 to be elastically deformed to a certain extent and then may pass through the hollow portion 12.

Therefore, compared with the scheme that the lens 50 cannot penetrate through the hollow part 12, the lens 50 can penetrate through the hollow part 12, and the plurality of elastic arms 14 which support the lens 50 together are arranged around the periphery of the hollow part 12, so that when the elastic arms 14 support the lens 50, the lens 50 can penetrate through the space surrounded by the plurality of elastic arms 14 and further penetrate through the hollow part 12, and the elastic arms 14 have a larger elastic adjusting space relatively, the range of the lens 50 subjected to external force can be larger, and the protection capability of the lens 50 is remarkably improved.

The hollow portion 12 may be a through hole or a blind hole, and the hollow portion 12 may also be a circular hole or an elliptical hole, etc., which is not limited in the present application.

For example, if the lens 50 is a ball lens, the hollow portion 12 may be a circular hole having a diameter larger than that of the ball lens. Alternatively, if the lens 50 is an ellipsoidal lens, the hollow portion 12 may be an elliptical hole through which the ellipsoidal lens passes.

In this embodiment, the elastic arm 14 includes a profiling portion 142 and an extending portion 144, the profiling portion 142 is provided with a profiling supporting surface 1420, the profiling supporting surface 1420 is used to fit with the outer wall of the lens 50, so as to provide a good support for the lens 50; the extension 144 is connected between a side of the contour 142 facing away from the lens 50 and an edge of the hollow 12, the extension 144 extending toward a center of the hollow 12.

When the lens 50 is forced to move into the hollow portion 12, the plurality of extending portions 144 are elastically deformed into the hollow portion 12, and the profile supporting surface 1420 is in contact with the outer wall of the lens 50.

When the elastic arms 14 are not elastically deformed, the corresponding extending portions 144 are arranged in a coplanar manner. In other embodiments, the extensions 144 may be disposed non-coplanar when the resilient arms 14 are not resiliently deformed.

As shown in fig. 4, the profile part 142 includes a profile sub-part 1421 and a supporting sub-part 1423, the profile sub-part 1421 is provided with the profile supporting surface 1420, one end of the supporting sub-part 1423 is connected to one end of the profile sub-part 1421 and is disposed at an acute angle to each other, and the other end of the supporting sub-part 1423 is vertically connected to the extending part 144.

Therefore, the supporting sub-portion 1423 and the profiling sub-portion 1421, which are disposed at an acute angle, deform when being pressed by the lens 50, and the acute angle between the supporting sub-portion 1423 and the profiling sub-portion 1421 is changed, so that the profiling supporting surface 1420 always fits to the outer wall of the lens 50, and the profiling sub-portion 1421 also plays a role of providing a buffering protection for the lens 50.

In other embodiments, the contoured portion 142 may also be block-shaped with a contoured support surface 1420 on one side and an opposite side connected to the extension 144; alternatively, the contoured portion 142 may be in the form of a shell, which is not limited in this application.
