The rotating member 41 rotates relative to the middle plate 10 through the first rotating shaft 50 and the second rotating shaft 60, and drives the image pickup device 42 and the receiver device 43 to open or close relative to the middle frame 100, so that the image pickup device 42 and the receiver device 43 can present two different use states.

Further, referring to fig. 15, the electronic device 200 includes a display screen 220, and the periphery of the display screen 220 is fixedly connected to the frame 20. One surface of the display screen 220 facing the middle plate 10 abuts against the front surface 11 and the first supporting surface 31, and the camera device 42 and the receiver device 43 rotate along with the rotating component 41 and are unfolded or stacked with the display screen 220. The display screen 220 is also supported against the second supporting surface 71. The middle plate 10, the first cover plate 30 and the second cover plate 70 support the display screen 220 together. The camera device 42 and the receiver device 43 rotate along with the rotating component 41 to the position where the camera device 42 and the receiver device 43 are overlapped with the display screen 220, the camera device 42 and the receiver device 43 are closed with the middle frame 100, and the camera device 42 and the receiver device 43 are covered by the display screen 220, so that the electronic device 200 is convenient for a user to carry. The camera device 42 and the receiver device 43 rotate along with the rotating part 41 to the position where the camera device 42 and the receiver device 43 are unfolded relative to the display screen 220, and the camera device 42 and the receiver device 43 are exposed from one side of the display screen 220, so that the corresponding functions can be realized conveniently. The Display screen 220 may be a Liquid Crystal Display (LCD) or an Organic Light-Emitting Display (OLED). The camera device 42 can shoot towards the side away from the display screen 220, and the camera device 42 achieves the function of a rear camera module. The receiver 43 can transmit the call sound to the user through the middle frame 100. When the rotating member 41 rotates relative to the middle frame 100 to the state where the display screen 220 is unfolded, the image pickup device 42 may photograph in the same direction as the display screen 220, and the image pickup device 42 implements a front camera function.
