Technical field

The utility model relates to a kind of advertisement, propaganda car that possesses large scale, high definition video, especially a kind of back projection type loudspeaker van.

Background technology

Existing media generally has two class technology: the first kind adopts spraying technology, a kind of be painted on car surface, another kind is to be sprayed on the lamp house cloth to be installed in then on the automobile facade.Its shortcoming is: picture still, replacing difficulty, poor in timeliness.The second series advertisements car adopts video technique, televisor or LED display device are installed on the automobile, shortcoming is: 1, the size of televisor is limited, present stage televisor size limitations below 50 inches, and but the installation dimension on the automobile is generally all greater than 80 inches, and the televisor more than 50 inches is owing to reasons such as technology, technology, output, and price is very high; If 2 adopt many televisor splicings, it is attractive in appearance then can to exist tangible piece to influence picture; Although 3, light-emitting diode display can large scale, the point of LED apart from very big, so differentiate rate variance, can't closely watch, let alone high definition.Because these shortcomings clearly, to such an extent as to the loudspeaker van of this class visual form is seldom seen in reality.

In addition, the media that has has been adorned projector and video screen at roof, though size is big and picture is clear.But the projection and play apparatus of this media is placed on outside the car, not only damages easily, the cost height, and is subjected to the restriction of traffic law, can not use in a lot of occasions.In addition, descend at inclement weathers such as rainy day, snow skies, this media also can't use.So present this media is not widely used.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of rear projection screen is arranged on back projection type loudspeaker van on the compartment wall, and not only size is big, picture is clear, and cost is low, result of use is good, be widely used.

The utility model solves the technical scheme that its technical matters adopts:

This back projection type loudspeaker van comprises bearing automobile, has display window on the compartment wall of bearing automobile, and the inboard of this display window is provided with rear projection screen, is provided with projector in the compartment.The utility model is arranged on wall inboard, compartment with rear projection screen, and projector is placed in the car, and projection and play apparatus is effectively protected, and is not easy to damage, and can both uses under various weather.

Further, rear projection screen is the thick screen of hard rear-projection, is fixed on the compartment wall by securing member, is positioned at the display window inboard.

But above-mentioned rear projection screen can be the rear-projection of scissor type formula and paste film, is pasted on the inboard of display window, also can be positioned at the inboard of display window, and be tightened on the metal framework for can drawing flexible rear-projection film.

For fully advertisement demonstration, the and arranged on left and right sides in compartment and rear portion all have display window.

The beneficial effects of the utility model: the utility model is owing to adopt large scale rear projection screen technology, maximally utilise self space of automobile, the display technique and the automobile of high definition are organically combined, and not only size is big, picture is clear, and cost is low, result of use is good.In addition, the utility model is arranged on wall inboard, compartment with rear projection screen, and projector is placed in the car, and projection and play apparatus is effectively protected, and is not easy to damage, and can both uses under various weather, helps promoting.
