The housing 100 has an opening 111 and an inner cavity 120. The inner cavity 120 is in communication with the opening 111. As described later, the driven device 500 can extend from the inner cavity 120 to the outside of the housing 100 through the opening 111. Of course, the driven device 500 can also be retracted into the inner cavity 120 from the outside of the housing 100 through the opening 111, thereby achieving concealment.

Generally, the housing 100 includes a frame 110, which may be a middle frame of the housing 100, and the frame 110 is used to enclose the inner cavity 120 of the housing 100 with other components of the housing 100 (such as a battery cover). The frame 110 can be provided with an opening 111. Of course, the opening 111 can also be opened in other parts of the casing 100, such as a battery cover. Some embodiments of the present disclosure do not limit the specific position of the opening 111 on the casing 100.

The driving mechanism 400 and the driving connecting member 300 are both arranged in the inner cavity 120, and the driving connecting member 300 is usually installed in the inner cavity 120 in a fixed manner. Specifically, the driving connector 300 may be fixedly connected to the housing 100. For example, the drive connector 300 can be fixedly connected to the housing 100 by means of clamping, bonding, screwing, or the like.
