In the technical scheme of this application, the core includes casing 200 and camera, and the camera is the camera function part of camera, and casing 200 is equipped with first inner chamber 210 and second inner chamber 220 and connecting hole 310, and first inner chamber 210 and second inner chamber 220 of connecting hole 310 intercommunication, and casing 200 rotationally sets up on the support, and the camera setting is in first inner chamber 210.

Specifically, the first lumen 210 and the second lumen 220 may be disposed adjacent to each other or may be spaced apart from each other by a distance. In the case that the first inner cavity 210 and the second inner cavity 220 are adjacently disposed, an opening may be directly disposed on the cavity wall of the first inner cavity 210 and the second inner cavity 220, so as to form the connection hole 310; in the case that the first inner chamber 210 and the second inner chamber 220 are spaced apart by a certain distance, a connector may be provided between the first inner chamber 210 and the second inner chamber 220, and a connection hole 310 may be opened on the connector, so that the connection hole 310 is connected to the first inner chamber 210 and the second inner chamber 220.

The driving device 400 includes a driving motor 410, the driving motor 410 is disposed in the second inner cavity 220, and the driving motor 410 is connected to the bracket. That is, the housing of the driving motor 410 is fixed in the second inner chamber 220, and the power output shaft of the driving motor 410 is connected to the bracket. Therefore, when the driving motor 410 works, the power output shaft rotates relative to the casing, and since the bracket is connected with the power output shaft, the bracket is fixed, and the power output shaft cannot rotate, the casing rotates relative to the power output shaft, and the casing drives the movement to rotate relative to the bracket.

Optionally, the housing of the driving motor 410 may be fixed in the second inner cavity 220 by welding, bonding, or the like, or the cavity wall of the second inner cavity 220 may be configured to be completely matched with the outer surface of the housing, and the cavity wall of the second inner cavity 220 is matched with the outer surface of the housing, so as to limit the driving motor 410 from moving relative to the second inner cavity 220.

Specifically, the first sealing portion may be a sealant or a sealing ring. In this way, the first inner cavity 210 and the second inner cavity 220 can be sealed without affecting the operation of the driving motor 410.

With such an arrangement, since the driving motor 410 is disposed inside the housing 200, the requirement for miniaturization of the body is satisfied; in addition, utilize first sealing part to seal up between first inner chamber 210 and the second inner chamber 220 and keep apart, adopt the static seal mode, even lubricating oil gets into in the second inner chamber 220, because first sealing part seals up first inner chamber 210 and second inner chamber 220 and keeps apart, lubricating oil can not further flow into first inner chamber 210 yet, also can not contact with the camera, and the sealing stability of camera improves.

In this embodiment, the electrical connector is a conductive wire, and the first sealing portion is a sealant. After the wire is connected with the driving motor 410 and the circuit board, the connecting hole 310 is sealed by a dispensing method.
