Rotary module with digital camera module
View Patent ↗A rotary module comprises: a digital camera module (DCM) electrically connected to a main body of an electronic product; a hinge assembly connected to a holding device (HD) and the main body, so as to allow relative rotation between the main body and the flip cover; a flexible printed circuit board (FPCB); and the HD to hold the DCM, and provide a wiring space for winding the FPCB and a hollow sleeve for receiving the hinge assembly. One end of the FPCB is connected to the DCM, and the rest extends along the flat surface of the HD, then winds around the wiring space, and finally connects to a PCB of either the main body or the flip cover. The rotary module could be disposed in an axial sleeve of flip-type cellular phone. When the flip cover is rotated, the HD and the DCM simultaneously rotate with the flip cover.
