Description
BACKGROUND OF THE
Generally, a display device such as a sign board is used to prohibit the entry of the surrounding vehicle in the event of an emergency such as construction of a road or an accident, or to display the progress of changing course. In this case, the signboard may be an LED or a halogen light emitting device for enhancing the visibility, or may be installed directly in the vehicle.
Although the signboard for vehicles has the advantage of being able to use the signboard for quick transportation to the accident or construction site, the signboard is usually used as a folding type supported by the gas spring, so the height is low, There is a problem that it is difficult to identify the signboard of the rear vehicle when the vehicle exists.
In view of such a problem, the sign board may be mounted on the front part of the vehicle luggage compartment or on the roof of the vehicle. However, when a cargo having a predetermined height or more is loaded in the loading space of the vehicle, the signboard of the sign board is covered, Respectively.
A technique of adjusting the height by vertically moving the sign board is also known (Registration Practical Utility Model No. 0411092). However, the sign board itself is constituted of a two-tiered structure which is lifted and lowered by the lifting cylinder, There is a limit to increase.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a vehicle display device capable of adjusting the height of three or more stages.
Another object of the present invention is to improve the working speed when adjusting the height of a display device for a vehicle, and to quickly perform work in an urgent field such as an accident scene or a construction site.
Another object of the present invention is to secure the reliability of the height adjusting operation while smoothly raising and lowering the post in the process of height adjustment in three or more stages.
According to an aspect of the present invention, there is provided a winch assembly including a plurality of posts that can be overlapped with each other, a winch assembly provided on a post fixedly installed in the plurality of posts, And the other end is connected to a post relatively moving with the fixed post, and is moved relative to the winch assembly while being wound or unwound on the winch assembly And driving means for raising and lowering the post.
A first post fixed to the plurality of posts and having a first inner space formed along a longitudinal direction thereof and having a winch assembly on the outside thereof and a second post accommodated in the first inner space so as to be able to move in and out, A second post accommodated in the second inner space so as to be able to move in and out of the second inner space and relatively movable with respect to the second post, .
Wherein the driving means is constituted by a first driving means and a second driving means and both ends of the first driving means are fixed to a lower portion of the winch assembly and the second post, And the second driving means is fixed at one end of the first post and at a lower portion of the third post, and both ends of the second driving means are fixed to the second inner space outlet edge of the second post, And extends to the lower portion of the third post.
Wherein a first pulley is provided at an exit edge of the first inner space so that the first driving means extends in a direction changing with respect to the first pulley and a second pulley is provided at an exit edge of the second inner space, And the second driving means is changed in direction with respect to the second pulley.
A gap maintaining / adjusting means is provided between the plurality of posts to maintain a constant gap between the plurality of posts.
The gap maintaining / adjusting means is constituted by a roller module, and is in rolling contact with the plurality of posts during relative movement.
The space maintaining / adjusting means is constituted by a block module, and the block module includes a block spacer provided between a plurality of posts and a fastener for adjusting the degree of protrusion of the block spacer.
The winch assembly includes a first gear to which a handle or a driving source is connected, and a second gear that is rotated in association with the first gear and is connected to a winder to which the first driving means is wound.
The first gear and the second gear are composed of a worm and a worm gear.
The following effects can be expected in the vehicle height display device according to the present invention as described above.
In the present invention, the plurality of posts overlapped with each other are unidirectionally expanded to increase the overall length thereof, so that the height of the display panel is sufficiently increased to three or more stages. Therefore, the contents of the display panel can be transmitted to a distance from the vehicle, thereby improving the identification performance of the vehicle display device.
According to the present invention, since the plurality of posts are connected to each other by the wire serving as the driving means and are extended at the same time, the entire length of the vehicle display device is extended, so that the operation speed for adjusting the height of the vehicle display device is improved, There is an effect to be improved.
Further, in the present invention, a gap maintaining / adjusting means is provided between a plurality of posts, so that a plurality of posts are spaced apart from each other at a predetermined interval, and are moved relative to each other. Accordingly, any one of the posts is inclined, It is possible to prevent a phenomenon that is not performed smoothly, and as a result, the operation reliability of the vehicle display device is improved.
