Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle equipped with display (projection) means.

[0002]

2. Description of the Related Art Conventionally, an automobile having an electrically lit display (advertising board) disposed on a side surface of a vehicle body for the purpose of outdoor events, sports broadcasting, advertising, or providing various information. Is used.

[0003]

Since these automobiles employ a light emitting mechanism such as a light emitting diode system as a display means, the power consumption is large, and the device becomes large with the light emitting mechanism. There were the following problems such as weight, durability, and vibration resistance, and no significant spread was observed. (1) The weight of the entire light emitting (projection) device is heavy. (2) Due to the heavy weight of the display, it was not possible to install the vehicle in a high position of a vehicle with a large advertising effect due to the limitation of the overturning angle in terms of vehicle design. (3) Since it is vulnerable to vibration, it lacks durability and requires high maintenance and management costs. (4) Power consumption is large and power supply equipment is required. (5) Production costs are high. (6) Due to the structure of the vehicle body, large panels could not be mounted in terms of strength.

Further, a conventional projection panel uses a panel made of acrylic resin or polycarbonate resin and has a small hole formed by a laser processing machine. These materials have low rigidity and are used as structural members. Could not be used. For this reason, when applied to a large vehicle such as a bus, the projection panel portion becomes a notch in the structure, and the strength and rigidity of the entire vehicle body is impaired, so that a large panel cannot be arranged. Furthermore, the projection equipment is bulky, and it has been difficult to achieve both the purpose of cargo and passenger transportation and the purpose of advertising. The problem to be solved by the present invention is to reduce the size of the light-emitting (projection) device by using a light-weight and highly durable light-emitting (projection) device, to use the same as a component member of the vehicle body, and to carry cargo / passenger transport, various events / advertisements, etc. The purpose of the present invention is to provide a vehicle compatible with providing information.

[0005]

Therefore, in order to solve the problem, the present invention provides a vehicle having a projection device for projecting an image on a part of a vehicle body, comprising: a projection device; and a light receiving portion for receiving light from the projection device. And an optical fiber having a light emitting section for emitting the received light, and a projection means comprising a projection panel, wherein the light emitting section of the optical fiber of the projection means is supported by the projection panel, and the projection panel is a component member of a vehicle body. Is provided. The projection panel is composed of a plastic honeycomb plate and a metal round plate, and the light emitting portion of the optical fiber is guided by the honeycomb core and is supported by the round hole of the round plate, or moves with respect to the vehicle body. It has a freely configured configuration.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment in which a projection device is mounted on a vehicle, for example, a truck. Vehicle 10
The side wall 17 of the carrier 15 is constituted by the projection panel 20. The projection panel 20 is vertically movable by being guided by the groove of the frame 19 of the side wall 17. The frame panel 19 is provided with a stopper (not shown) so that the projection panel 20 can be stopped at an appropriate position. 2 and 3 show a projection device and a projection panel mounted on the vehicle 10, FIG. 2 is a conceptual diagram of the projection device, and FIG. 3 is a perspective view of the projection panel. The projection device 200 is a liquid crystal projector-21.
The image from the projector such as 0 is received by the light receiving unit 220 and projected on the projection panel 20. The light receiving section 220 and the projection panel 20 are connected by an optical fiber 230. The light receiving unit 220 is formed by bundling the optical fibers 230 with one end surfaces thereof aligned, and the other end surface of the optical fibers 230 is supported by the projection panel 20. As shown in FIG. 3, the projection panel 20 includes a honeycomb plate 23 and a round plate 25 covering the surface of the honeycomb plate 23.

The honeycomb plate 23 is a plate made of an acrylic plate having a thickness H of 20 to 50 mm and having a honeycomb core 233 connected thereto. The round punched plate 25 is a metal plate having small holes 250 perforated at intervals of the honeycomb core 233 and having a thickness h of 0.5 mm. For example, the interval between the small holes 250 is set according to the enlargement ratio of the spherical portion 20 of the optical fiber 230. The optical fiber 230 is provided with the honeycomb core 233 of the projection panel 20 configured as described above as a guide groove. Then, the optical fiber 230 is arranged with the light emitting tip portion inserted into the small hole 250. At this time, one optical fiber 230 is connected to the light receiving section 220 and the projection panel 20.
Are arranged so as to connect the same phase with.

[0008] The projection apparatus 200 having the above-described configuration allows the image light projected by the liquid crystal projector 210 to receive the image light 220
Is transmitted through the optical fiber 230 to reach the tip and emit light. In the projection panel 20 configured as described above, a lightweight projection panel (video display) 20 can be configured by the honeycomb plate 23 made of an acrylic plate, and the surface is covered with a round punched plate 25 made of a metal plate. Therefore, it has strength and rigidity as a vehicle body and can also serve as a structural member of the vehicle body. Therefore, the vehicle 10 has the projection panel 2
0 is used as a structural member as a side wall of the loading platform 15, and a lifting mechanism for sliding the lightweight projection panel 20 up and down can be executed with a simple configuration. And
Normally, the projection panel 20 is provided as a side wall of the loading platform 15, and becomes a display (projection panel) 20 for projecting an image by appropriately operating the projection device 200. Also, if necessary, slide the projection panel 20 to
If it is arranged at a high position, the saliency is high and the advertising effect and information transmission effect increase.

In the embodiment shown in FIG. 4, the projection panel 30 is disposed on the side wall of the bus 300. This bus 3
In the reference numeral 00, the projection panel 30 is provided as a wall structural member, and an image is displayed on the projection panel 30 by operating the projection device as necessary. Even in this case,
Since the projection panel 30 is composed of a honeycomb plate and a round metal plate, it is a rigid and lightweight panel which is easy to handle and is installed as a structural member of a bus body to transport and report passengers. A bus can be provided that is compatible with providing information such as advertisements.

[0010]

Since the vehicle of the present invention has a large and lightweight projection panel, it has a high advertising effect and a high information transmission effect. Further, the projection panel included in this vehicle is a lightweight and highly durable panel, which can bear strength on the vehicle structure, so that it becomes a constituent member of a vehicle body, for example, a wall member, and the structural design of the vehicle becomes easy. Thus, the applicable range can be expanded. Furthermore, by making the projection device compact, it is possible to provide a vehicle that achieves both cargo / passenger transportation and the purpose of advertising.
