In addition, after the connection portion 150 is connected to the lens, the light hole 110 corresponds to an imaging direction of the lens.

In addition, in the present embodiment, the lens cover 400 and the mounting base 300 can also be damped to rotate, and after the lens cover 400 is opened, the lens cover 400 is in a stable state, so as to avoid that the lens cover 400 shakes to influence shooting or projection of a user in the process of using the lens, and ensure the use experience of the user.

In an embodiment, referring to fig. 1 to 4, the lens cover assembly further includes a damping member 200, where the damping member 200 is sandwiched between the first mounting portion 120 and the second mounting portion 310. In this way, in the process of rotating the mount 300 by the user, the damping member 200 can provide damping force, so that the user rotates the mount 300 more smoothly, and accidental impact or vibration is reduced.

Specifically, the damping members 200 may be disposed at intervals or annularly and continuously between the first and second mounting portions 120 and 310, and in this embodiment, please continue to refer to fig. 1 to 3, the damping members 200 are disposed annularly, and it is understood that the damping members 200 abut against opposite sides of the first and second mounting portions 120 and 310 in the circumferential direction between the first and second mounting portions 120 and 310, so that the damping members 300 can provide an even damping force distribution during the user's rotation of the mounting base 300, so that the entire rotation process is smoother.

And, the first receiving groove 130 and the second receiving groove 320 are concavely formed at diametrically opposite sides of the first mounting portion 120 and the second mounting portion 310, respectively, and the damper 200 is interference-fitted between the first receiving groove 130 and the second receiving groove 320.
