Specifically, the multifunctional projection display vehicle-mounted system 20 comprises a projection module 21, an imaging film 22 for projection imaging, a mounting component 23 for mounting the projection module, a control unit 24 and a voice module 25. The projection module 21 and the voice module 25 are respectively connected to the control unit 24. Preferably, the projection module 21 is a projector with a projection lens, and the voice module 25 is a sound box.
It should be understood that the control unit 24 is configured to send the played video information to the projection module 21, and also send the voice information corresponding to the video information to the voice module 25, so that the projection module 21 and the voice module 25 can synchronously project video and broadcast voice, respectively.
Alternatively, the control unit 24 may be an electronic device with video and audio storage, such as a mobile phone, a tablet computer, a usb disk, or an optical drive.
The imaging film 22 may be obtained by printing a commercially available transparent holographic film as a base film, but the invention is not limited thereto. Further, the imaging film 22 is attached to the inner surfaces of the side door windows and the rear windshield.
In this embodiment, the projection lens of the projection module 21 can project in multiple directions, and the imaging film 22 is attached to the window of each projection direction of the projection lens; the projection module 21 projects light to the imaging film 22 to realize projection imaging.
The mounting assembly 23 includes: the sliding mechanism comprises a sliding rail 231 mounted on the inner wall of the roof, a sliding block 232 arranged on the sliding rail 231 in a sliding manner, and a connecting rotating shaft component 233 driven by the sliding block 232. Furthermore, the connecting shaft assembly 23 connects the projection module 21 and the slider 232. In the present embodiment, the slide rail 231 extends in the width direction of the vehicle, i.e., perpendicular to the advancing direction of the vehicle.
As for the connecting rotary shaft assembly 233, the connecting rotary shaft assembly 233 includes a vertical rotary shaft 234 and a horizontal rotary shaft 235 hinged to each other. The vertical shaft 234 is horizontally disposed and can vertically rotate with respect to the slider 231, and the horizontal shaft 235 is horizontally disposed and can horizontally rotate around the vertical shaft 234.
