JPH0664426B2 - Assembly method for in-vehicle large display device - Google Patents

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention stores a large-sized display device as a medium for transmitting a large amount of information on a vehicle and moves it to quickly form a large-sized screen at a place where an image is displayed. The present invention relates to a method of assembling an in-vehicle large-sized display device that can be performed.

2. Description of the Related Art Conventionally, a method described in Japanese Patent Application No. 58-1412 shown in FIGS. 5 and 6 is used as a configuration that can be downsized to a shape that meets safety standards when moving onboard and can realize a sufficiently large integrated screen when broadcasting. is there. In order to assemble the upper display section 6 and the lower display section 7 mounted side by side on the floor of the vehicle 1 in the figure, the outriggers 2 are lowered and fixed in order to keep the vehicle stable after the vehicle is moved. Next, after the cover 3 is unfolded, the tilt plate 4 is lowered, the vertical display cylinder 5 using a hydraulic device raises the upper display portion 6 to a predetermined position, and the push cylinder 7 pushes the lower display portion 8 to the upper display portion 6. The upper and lower display portions 6 and 8 are fitted together by pushing down to the lower surface and lowering the vertical cylinder 5 to form an integrated screen.

Problems to be Solved by the Invention However, in the above-described conventional configuration, it is possible that the vehicle is easily located in a place where the height of the center of gravity during traveling is high, and therefore it may be considered a problem from the viewpoint of rollover prevention.

It is an object of the present invention to provide a method for assembling a large-sized on-vehicle display device which eliminates the above-mentioned drawbacks of the prior art and allows easy multi-stage loading with a simple structure.

Means for Solving the Problems In order to achieve the above object, the present invention divides a large display screen into two parts and installs them on a floor surface on a car (bellows type) and installs them on the upper screen. The corresponding display device is pulled up and the next display device is raised under the corresponding display device to form an integrated display screen connected to each other.

Effect Since the present invention is configured as described above, the height of the center of gravity is lower than in the conventional example, safe driving can be obtained, and the operation is simple, and it is also effective when the screen is divided into two or more parts and assembled. Have.

Embodiments Embodiments of the present invention will be described below with reference to FIGS. 1 to 4. In these figures, 9 is the floor of the vehicle, 10 is the vehicle,
1 is an outrigger for stably installing the vehicle, 2 is an upper display device, 3 is a main first hydraulic cylinder, 4 is a sub second hydraulic cylinder, and 5a and 5b are auxiliary third and fourth hydraulic cylinders.
, 6 is a lower display device, 7 is a bearing for connecting the upper and lower display devices, and 8 is a roller for facilitating the movement of the floor surface 9 by the lower display device 6.

Next, the assembling operation will be described in the above embodiment. First, the outrigger 1 is lowered and fixed to the ground in order to keep the vehicle 10 stable, and then the pressures of the first to fourth hydraulic cylinders 3, 4, 5a, 5b are raised in order to raise the upper and lower display devices 2, 6. Is set in advance and driven, the upper display device 2 and the lower display device 6 start up as shown in FIG. At that time, as shown in FIG. 4, the roller 8 provided on the lower surface of the lower display device 6 is placed on the floor 9
The stepped corners can be easily moved, and finally, the upper and lower divided upper and lower display devices 2 and 6 can be assembled into an integrated structure and aired, which is completed.

When returning to the original state, the above assembly operation may be performed in reverse.

EFFECTS OF THE INVENTION According to the present invention as described in the above embodiments, the upper and lower display devices are stable because the upper and lower display devices are folded down with each other in the transportation state, and the upper and lower display devices are simply hydraulically driven with the bearing as the center. Since the cylinder may be extended and assembled, it has an advantage that the structure is simple.
