Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a mobile display device, particularly a vehicle-mounted display device.

It is known that information is provided by displaying characters and images on a display screen formed by arranging a large number of light emitting elements in a matrix, but the present invention particularly provides a method for mounting such a display screen on a vehicle. This invention relates to the improvement of a vehicle-mounted display device that is carried to a place where many people gather and is mounted on a vehicle to provide video information to the crowd.

[Conventional technology]

In this type of vehicle-mounted display device, two display boards each consisting of a large number of light emitting elements are placed side by side on a vehicle chassis, and when transported to a destination, one display board (upper display board) is moved to the other on the vehicle chassis. It is used as a two-tiered large screen by standing it upside down on top of the display board (lower display board). The upper display board and the lower display board are connected by a hinge, and the upper display board is designed to be rotated upside down on top of the lower display board by a lifting mechanism including a hydraulic cylinder. When the vehicle is running, the two display boards are placed side by side on the vehicle chassis, and a cover is placed to surround these two display boards, and when in use, the surrounding cover is removed and the upper display board is stacked on top of the lower display board.

[Problem that the invention seeks to solve]

Putting a cover on the display board or removing the cover from the display board is a difficult task because the cover is large and weighs a lot, and even after the cover is removed, there is a problem in storing it. .

[Means and effects for solving the problems] An object of the present invention is to solve the above problems, to easily attach and detach the cover with a simple structure, and to use the removed cover as a surrounding side wall of the vehicle chassis during use. It is an object of the present invention to provide an on-vehicle display device equipped with a cover device that allows the display device to be mounted on a vehicle.

According to the present invention, a bendable flat plate whose lower edge is rotatably attached to the side edge of the vehicle chassis and covers the entire surface of the display board in an extended state, and this flat plate is rotated and extended to cover each display board;
The cover device consists of a flat plate control mechanism that controls the movement of the flat plate so that it rotates and bends to cover the undercarriage. The above object can be achieved by constructing the flat plate from a first flat plate part whose width is equal to the height of the vehicle chassis, and a second flat plate part which is attached to this flat plate part by a hinge and whose width corresponds to the height of the vehicle chassis. achieved.

゛.

When the display board is not in use or when the display board is running, the first flat plate part and the second
The first flat plate part is extended to stand upright from the side edge of the chassis to cover the side of the display board, and when in use, the first flat plate part is extended horizontally from the side edge of the chassis, and then the first flat plate part is The second flat plate portion is extended vertically downward so that the edge of the second flat plate portion hangs down or contacts the ground to cover the chassis and outriggers.

〔Example〕

FIG. 1 is a schematic diagram of the vehicle-mounted display device of the present invention viewed from the rear. FIG. 2 is a perspective view of a cover device for a vehicle-mounted display device according to the present invention.

As shown in Figure 1, when not in use or when driving, two display boards 1 and 2 are placed side by side on the chassis 3, and when in use, the other display board is placed on the lower display board (lower display board) 1. (Upper display board) 2 is rotated upside down around hinge 4 by a display board lifting mechanism (not shown) to form two stacks (see broken lines)
.

The cover device is attached so that its lower edge A can be rotated to the side edge of the vehicle chassis, and includes a flat plate that can be bent to cover the entire surface of each display panel 1 and 2 in an extended state, and a flat plate l that can be rotated around the lower edge A. It moves and extends to cover each of the display boards 1 and 2 (see broken lines), and then rotates around the lower edge A and bends at the hinge B to cover the chassis 3, especially the outrigger 6 that fixes the vehicle stationary. It includes a flat plate control mechanism (not shown) that uses a hydraulic device or the like to control the movement of the flat plate.

The flat plate 1 is rotatably attached to the side edge A of the undercarriage 3, and is attached to a first flat plate part 51 having a width equal to the height H of the display board minus the height h of the undercarriage, and to this flat plate part by a hinge. ,
and a second flat plate portion 52 having a width corresponding to the height h of the vehicle chassis. Furthermore, a buffer member 53 is provided along the free edge of the second flat plate portion 52, and a l-i rotor mechanism is provided on the hinge connecting the first and second flat plate portions.

When not in use or when driving, the flat plate 1 is applied to the entire surface of the display plates 1 and 2 to cover it, and when in use, the flat plate is applied to the side edge A of the chassis.
, and tilt the first flat plate portion 51 to a position approximately perpendicular to the display panels 1 and 2. Further, the second flat plate part 52 is tilted down about the hinge B to a position substantially perpendicular to the first flat plate part 51, so as to cover the side surface of the vehicle body. This operation is performed using hydraulic cylinders or the like provided at both ends of the flat plate.

When covering the display plates 1' and 2, first cover the second flat plate part 5.
2 is lifted up until it is aligned with the first flat plate portion 51 and locked by a locking mechanism so that this state can be maintained. Next, lift the entire flat plate using a hydraulic cylinder, etc. A buffer member 55 at the free end of the flat plate is fixed to the upper end of the display plate 1°2.

〔effect〕

The entire display surface is covered when not in use or when the vehicle is running, and this surface can also be used as an advertising bulletin board.

There is no need to store the cover during use, and the outriggers or the side surfaces of the chassis are covered, resulting in a favorable appearance.
