Detailed Description

The invention will be further described with reference to the accompanying figures 1-4.

Example 1

As shown in figures 1-3, the bus-mounted projection device with multi-directional projection is characterized in that a guide rail (5) is arranged on the roof of the middle of a bus (7), a projector (2) is connected with the guide rail (5) through a connecting part (4), a projector lens light path (3) is opposite to a projection display surface (1), the connecting part (4) consists of a connecting head (4-1), a connecting rod (4-2) and a first disc (4-3) which are sequentially connected from top to bottom, the connecting head (4-1) can slide on the guide rail (5), the first disc (4-3) can be rotatably connected with the projector (2), and the projection display surface (1) is arranged on the front of the bus and/or the side of the bus. Guide rail holes (5-1) are symmetrically formed in the side portions of the guide rail (5), the lock columns (6) can penetrate through the guide rail holes (5-1), and the positions of the joint heads (4-1) in the guide rail can be fixed by the two lock columns (6) as shown in fig. 2. The projector is a laser projector and is provided with a vehicle-scale DLP projection chip (the model of the product can be sold in the existing market). The projection display surface is electrically controlled liquid crystal glass or glass with an imaging film inside.

The liquid crystal interlayer is arranged in the electric control liquid crystal glass, when the power is off, the electric control liquid crystal glass is in an opaque state, and a projector can be used for directly projecting and imaging on the surface of the glass to play a role of a display screen; when the vehicle is electrified, the structure of the liquid crystal molecules inside the vehicle is changed, the electric control liquid crystal glass is changed into a transparent state, the light transmission effect can be achieved, and the lighting environment in the vehicle is more transparent. The inside has formation of image film glass, is transparent glass when normal, when the projector is opened, can directly be at the formation of image of glass surface, plays the effect of display screen. According to different interlayer films, the single-sided imaging and the double-sided imaging can be realized. The electric control liquid crystal glass and the glass with the imaging film inside can be selected from commercially available products.

Furthermore, 4 clamping blocks (4-31) are arranged on the first disc (4-3), the adjacent clamping blocks (4-31) are 90 degrees, the 4 clamping blocks are 2 first-direction clamping blocks and 2 second-direction clamping blocks, 4 clamping seats are arranged at the top of the projector (2), the adjacent clamping seats are 90 degrees, and the clamping blocks and the clamping seats can be detachably matched; the 4 clamping seats are 2 longitudinal clamping seats (2-1) and 2 transverse clamping seats (2-2). The working process is as follows: as shown in fig. 2, when the front portion projects, the first direction block is engaged with the longitudinal clamping seat, and the second direction block is engaged with the transverse clamping seat; when the front projection is required to be turned to the side projection, the clamping block and the clamping seat are detached, the first disc is rotated by 90 degrees, so that the first direction clamping block is matched with the transverse clamping seat, and the second direction clamping block is matched with the longitudinal clamping seat.
