In an embodiment, a damping structure 25 is disposed between the adjusting portion 21 and the housing 10, and the locking member 30 presses against the adjusting portion 21 in the locking state, so that the damping structure 25 presses against the housing 10 to lock the rotation angle of the rotating member 50.

The damping structure 25 can increase a frictional force of relative rotation between the adjusting part 21 and the housing 10 to prevent the adjusting piece 20 from rotating relative to the housing 10 in a locked state, thereby improving stability of the rotational angle locking of the rotating piece 50. In addition, when the acting force between the adjusting part 20 and the casing 10 is smaller than the locking pressure and the two are not completely separated, the damping structure 25 can improve the feeling when the adjusting part 20 rotates the rotation angle of the adjusting rotation part 50.

In an alternative embodiment, the damping structure 25 is disposed at least on a surface of the adjusting portion 21 facing the casing 10. In an alternative embodiment, the damping structure 25 includes a friction surface provided on at least one of the adjusting portion 21 and the casing 10. The friction surface has a large friction coefficient, and when the adjustment portion 21 rotates relative to the housing 10, the friction surface can increase the resistance force applied when the adjustment portion 21 rotates, thereby improving the stability of the locking member 30. For example, the adjustment portion 21 is provided with a friction surface having a large friction coefficient such as a friction pattern or a wavy pattern, which is located on the surface of the arm 22 on the side from which the arm projects. Or the surface of the casing 10 is provided with a friction surface with large friction coefficient, such as a grinding pattern, an undulating pattern and the like, and the arc-shaped hole 11 is positioned in the friction surface range. In some embodiments, the damping structure 25 is disposed on a surface of the adjusting portion 21 facing the housing 10, and is integrated with the adjusting portion 21. The damping structure 25 may be a friction surface formed on a surface of the adjustment portion 21 facing the casing 10. Therefore, the adjusting and locking part structure is integrated, the structure is simple, the number of parts is small, and the assembly is simplified.

In another optional embodiment, the damping structure 25 includes a damping member disposed between the adjusting portion 21 and the casing 10, and the damping member is elastically abutted between the casing 10 and the adjusting portion 21. The damper is located at a portion where the adjusting portion 21 and the casing 10 relatively rotate to increase a rotational resistance between the casing 10 and the adjusting portion 21. For example, the damping member is a rubber ring sleeved on the supporting arm 22, and the rubber ring is elastically deformed under the pressing force of the casing 10 and the adjusting portion 21.

In one embodiment, the camera device comprises a lens assembly 60 and a lens mounting device as disclosed in the above embodiments, wherein the lens assembly 60 is mounted on the rotation member 50.

The lens assembly 60 is mounted to the rotation member 50 and rotates together with the rotation member 50. The adjusting member 20 passes through the housing 10 and is movably connected with the rotating member 50, and the locking member 30 is connected with the locking adjusting member 20 to limit the shooting angle of the lens assembly 60, so that the lens assembly 60 is prevented from being interfered by external force, and the angle adjusting precision is high. The adjusting ends of the locking member 30 and the adjusting member 20 are both located outside the casing 10, and the adjustment is convenient.

In an alternative embodiment, the camera device is provided with two or more lens assemblies 60, the lens assemblies 60 correspond to different sides of the casing 10, and each lens assembly 60 is independently adjusted through the corresponding locking member 30 and the corresponding adjusting member 20, so that the adjustment is convenient.

The present invention is not intended to be limited to the particular embodiments shown and described, but is to be accorded the widest scope consistent with the principles and novel features herein disclosed.
