Vehicle with projection device and projection method thereof

technical field

The invention relates to the field of vehicles, in particular to a vehicle with a projection device and a projection method thereof.

Background technique

In recent years, the number of cars has been increasing day by day, and the use of cars to advertise has become one of the important propaganda methods for major businesses. A common way of publicity is to paste advertising posters on the body of the car to obtain a larger publicity area to attract the attention of the surrounding people. However, the cost of making advertising posters that match the model is high. Secondly, it takes a lot of time and labor costs to evenly paste the advertising posters on the car body. Moreover, the advertising posters covering the surface of the car seriously affect the overall beauty of the car, and indirectly affect the image of the city. In addition, in the process of tearing off the poster, it is necessary to avoid damage to the surface of the car, which requires high professional ability and proficiency of the operator.

Some advertising posters are pasted on the rear window glass of the car, which can be more clearly noticed by pedestrians and vehicles around the car to increase the propaganda of the advertisement. However, the advertisement poster covering the rear window glass not only affects the overall appearance of the car, but also the advertisement poster always blocks the rear window glass, blocking the driver's sight, and it is difficult for the driver to directly observe the vehicle behind the vehicle through the rear window glass. The environment seriously affects the driving safety.

In addition, the content of the advertising posters pasted on the body of the car or the rear window glass is fixed and single, and different contents can be promoted only by replacing different advertising posters, which increases the cost of advertising. Moreover, the replacement time of advertising posters is usually faster, and the advertising posters are frequently replaced, which is complicated in operation and high in cost. In addition, most of the existing advertising posters are made of plastic, and the replaced advertising posters can only be discarded, resulting in waste of resources and not conducive to environmental protection.
