at least one of the first region, the second region, the third region and the fourth region is a light-transmitting region, and at least one region is a projection region.
4. An energy efficient in-vehicle projection system as claimed in claim 3, wherein: the color of the light-transmitting area is colorless and transparent, and the color of the projection area is black and opaque.
5. The energy efficient in-vehicle projection system of claim 1, wherein:
the color-changing glass is liquid crystal glass;
the liquid crystal glass changes the transparency of different areas based on electric signals to form a light transmitting area and a projection area.
6. The energy efficient in-vehicle projection system of claim 1, wherein: the projector (2) is positioned on a table plate (4) arranged on the rear row of the vehicle, and the projector (2) is rotatably connected with the table plate (4) through a rotating table (5) with a rotating angle recording function.
7. The energy efficient in-vehicle projection system of claim 6, wherein:
also comprises a position sensor (3);
the position sensor (3) is positioned on a side window glass (1) of a passenger area at the rear row of the vehicle;
the position sensor (3) is used for determining a projection area of the projector (2) based on the position of the projector (2) on the table plate (4) and the rotation angle of the rotating table (5);
the controller adjusts the transparency of the color-changing glass to determine the position of the projection area based on the projection area of the projector (2), and adjusts the transparency of the color-changing glass to determine the position of the light-transmitting area based on the position of the projector (2) on the table (4).
8. The energy efficient in-vehicle projection system of claim 7, wherein: the position sensor (3) determines the position of the projector (2) on the table (4) based on the plane coordinate system on the table (4).
9. The energy efficient in-vehicle projection system of claim 6, wherein:
the table board (4) is also provided with a laser projection keyboard (6), the keyboard projected by the laser projection keyboard (6) is positioned on the table board (4), and the laser projection keyboard (6) is provided with a solar component;
the controller is also used for adjusting the transparency of the color-changing glass, so that the area, facing the laser projection keyboard (6), of the side window glass (1) is a non-light-transmitting area, and the area, facing the laser projection keyboard (6), of the side window glass is a light-transmitting area.
10. The energy efficient in-vehicle projection system of claim 9, wherein:
the laser projection keyboard (6) generates a control signal based on the clicking operation of the keyboard projected on the desk board (4), and transmits the control signal to the intelligent mobile device;
the intelligent mobile equipment receives the control signal sent by the laser projection keyboard (6) and responds to the operation action corresponding to the control signal.
