An accommodating slot 35 is defined in the body 30 for receiving the camera module 20 , the gravity structure 40 and the locking structure 50 . In the embodiment, the accommodating groove 35 is opened on the first end 31 of the body 30. The accommodating groove 35 includes two opposite side walls 351. Each of the side walls 351 defines a mounting hole 353. Each of the mounting holes 353 is configured to rotatably receive the end of one of the rotating shafts 211. Thus, the camera module 20 can be rotated by the rotating shaft 211 and the mounting hole 353. The body 30 is rotatably mounted. In the embodiment, the sidewall 351 extends along the longitudinal direction of the portable electronic device 100 , that is, the extending direction of the sidewall 351 is the same as the connection between the first end 31 and the second end 33 of the body 30 . In addition, the connection direction of the two mounting holes 353 is perpendicular to the longitudinal direction of the portable electronic device 100, that is, the lateral direction of the portable electronic device 100. Thus, the camera module 20 can be in the longitudinal direction of the portable electronic device 100. The direction is rotated to adjust the shooting angle of the camera module 20 along the longitudinal direction of the portable electronic device 100, and further adjust the framing and shooting range of the camera module 20.

The gravity structure 40 is configured to provide a driving force to drive the rotation of the camera module 20 . The gravity structure 40 is fixedly connected to the camera module 20 and disposed on a side of the camera module 20 facing the second end 33 . In the present embodiment, the gravity structure 40 is fixed to the base 21 of the camera module 20 . The gravity structure 40 includes a link 41 and a starting member 43. One end of the connecting rod 41 is fixed to the base 21, and the other end is connected to the starting member 43. In the present embodiment, a receiving slot 213 is defined in each of the rotating shafts 211. One end of the connecting rod 41 is fixedly received in the receiving slot 213. The starting member 43 is disposed at an opposite end of the connecting rod 41 connected to the rotating shaft 211. It can be understood that the connecting rod 41 and the starting member 43 can be integrated.

It can be understood that the extending direction of the connecting rod 41 is parallel to the connecting direction of the first end 31 and the second end 33.

The actuating member 43 may be made of metal, plastic or the like, and may have a diameter slightly smaller than the diameter of the connecting rod 41. The starting member 43 has a certain weight. Thus, the starting member 43 can drive the camera module 20 to rotate under the action of gravity. Specifically, when the portable electronic device 100 is normally held in a vertical screen and the portable electronic device 100 is operated in a vertical screen, the portable electronic device 100 is in use. The electronic device 100 is at an acute angle to the horizontal direction, and the starting member 43 moves away from the end of the accommodating slot 35 of the portable electronic device 100 under the action of gravity, and the camera module 20 is close to the gravity structure 40. The one end of the camera module 20 is moved toward the accommodating slot 35, so that the camera module 20 has an upward tilt angle, so that the camera module 20 has an upward tilt angle. The camera module 20 has a farther viewing angle range, so that the camera module 20 can capture a scene farther away from the user, such as road condition information, so that the user can know the road condition information in advance to avoid accidents. The upward angle is an angle between a central axis of the camera module 20 and a plane perpendicular to the longitudinal direction of the portable electronic device 100.

Referring to FIG. 4 and FIG. 5 , the locking structure 50 is connected to the camera module 20 for controlling the camera module 20 to be in a rotatable state or a locked state (ie, a non-rotatable state). The locking structure 50 includes a driving member 51 for providing a driving force, and the matching member 53 controls the camera module 20 to be in a rotatable state or a locked state. The driving member 51 can be a motor or a solenoid valve. The engaging member 53 is movably disposed in the receiving groove 35 of the body 30 under the driving of the driving member 51, and the moving direction of the engaging member 53 is perpendicular to the longitudinal direction of the portable electronic device 100.

In this embodiment, the driving member 51 is a stepping motor, and the fitting member 53 is a jack. Specifically, when the driving member 51 drives the engaging member 53 to move toward the end of the camera module 20, the engaging member 53 is driven by the driving member 51 to abut the base 21 of the camera module 20, and the base 21 is The driving force of the engaging member 53 is moved toward the cover body 60 until the central axis of the camera module 20 is perpendicular to the longitudinal direction of the portable electronic device 100, due to the abutment of the engaging member 53.
