[0072] Optionally, on the basis of the cover 10, a protective cover structure is further arranged, the movement of the protective cover is realized through the driving member, thereby opening when the camera 20 is working and closing when the camera 20 is turned off, and the protection effect is further improved.

[0073] The above only describes the preferred embodiments of the present application, and does not limit the patent range of the present application. Any equivalent structural transformation or direct / indirect application in other related technical fields under the concept of the present application and according to the content of the present application is included in the patent protection range of the present application.
