FIG. 1 illustrates a vehicle to which a height-adjustable vehicle display device according to the present invention is applied.

As described above, a vehicle display device 100 (hereinafter, referred to as 'vehicle display device') capable of height adjustment according to the present invention is for recognizing a specific sign on the vehicle 1, In the embodiment, a directional marker that induces a lane change of the vehicle by using a halogen lamp or an LED lamp is used as the vehicle display device 100. [ In this case, the height of the display panel 500 of the vehicle display device 100 according to the present invention can be adjusted so that the visibility can be secured to a relatively long distance. In FIG. 2, the height of the vehicle display device 100 increases Is shown. The specific structure related to the height adjustment will be described below.

First, the appearance and skeleton of the display device 100 for a vehicle according to the present invention are formed by a plurality of posts 300. The plurality of posts 300 may overlap each other, and the plurality of posts 300 may extend in a direction in which the posts 300 are extended or may be overlapped with each other in a folding direction to control the overall height of the vehicle display device 100 .

The plurality of posts 300 are installed stably by seating a large area of the base plate 200 fixed through welding with the first posts 310 on the bottom of the vehicle. Fastened or welded using fastening means such as bolts, or simply seated.

The first post 310 can be firmly fixed to the vehicle frame 10 by the mounting assembly 700. 4, the mounting assembly 700 includes a vertical frame 710 and a horizontal frame 720, and a mounting bracket 730 bent in a 'C' shape is formed in the horizontal frame 720 The mounting bracket 730 is coupled to the horizontal frame 720 with the vehicle frame 10 wrapped around it so that the mounting assembly 700 engages the first post 310 with the vehicle.

The display device 100 for a vehicle according to the present invention may include two or more than three posts 300 that can be overlapped with each other. In this embodiment, the display device 100 includes three posts in total. The first post 310, which is the outermost post among the plurality of posts 300, is fixedly installed, which means that the post remains fixed to the vehicle without lifting the post.

The winch assembly 320 is installed on the outermost first post 310 fixedly installed. The winch assembly 320 provides a driving force for adjusting the height of the vehicle display device 100 by winding or unwinding the driving means W1 and W2 by using a rotational force by a manual or motor.

More specifically, as shown in FIG. 5, the winch assembly 320 includes a housing 320 'that forms a skeleton thereof, a first gear 322 and a second gear 322 interlocked with each other inside the housing 320' And a gear 325. The first gear 322 is connected to the handle 321 and can be rotated through the rotation of the handle 321. Of course, the first gear 322 may be automatically rotated by using a driving source such as a motor instead of the knob 321. [

The second gear 325 is connected to a winder 324 which rotates in conjunction with the first gear 322 and winds the first driving means W1 to be described later. When the first gear 322 is rotated clockwise or counterclockwise, the second gear 325 is rotated to rotate the winder 324 so that the first driving unit W1 rotates the winder 324, And is released from the winder 324. [

When the first gear 322 stops rotating at an arbitrary position, the first gear 322 and the second gear 325 associated therewith are prevented from being arbitrarily rotated by the brake mechanism 329, The height of the vehicle display device 100 is maintained.

In this embodiment, the first gear 322 and the second gear 325 are configured as spur gears. The internal operating structure of the winch assembly 320 is not limited to the example shown in FIG. For example, three or more gears may be provided inside the winch assembly 320, or the winder 324 may be directly connected to the handle 321 without a separate gear.

8, the first gear 322 may be a worm 323, and the second gear 325 may be a worm gear. That is, the first gear 322 and the second gear 325 have rotation axes extending in directions orthogonal to each other. Thus, even if there is no separate stopper or brake mechanism 329, 1 gear 322 can be prevented from being arbitrarily rotated in the reverse direction.

Meanwhile, in this embodiment, the plurality of posts 300 are composed of first to third posts 310, 330 and 350. The first post 310 is fixedly installed, the first inner space is formed along the longitudinal direction, and the winch assembly 320 is provided on the outside. The second post 330 is accommodated in the first inner space so as to be able to move in and out of the first inner space and relatively movable with respect to the first post 310. A second inner space is formed along the longitudinal direction of the second post 330, 350 are accommodated in the second inner space so as to be able to move in and out of the second inner space and are movable relative to the second post 330 and a display panel 500 to be described later is coupled to the outside.

The first post 310, the second post 330, and the third post 350 are overlapped with each other. In the first post 310 having the widest width, the second post 330 is inserted into the first post 310, And the third post 350 is accommodated in the second post 330.

The third post 350 is provided with a fastening bracket 390. The fastening bracket 390 is for coupling with the display panel 500 and may be provided on both sides as shown in FIG.

The plurality of posts 300 are provided with driving means W1 and W2 so that the plurality of posts 300 move relative to each other according to the operation of the winch assembly 320. [ One end of the driving means W1 and W2 is connected to the winch assembly 320 and the other end is connected to a post relatively moving with the fixed first post 310 to be wound on the winch assembly 320 So that the post that is relatively moved is raised and lowered.

Here, the driving means W1 and W2 may be configured in the form of a wire, a chain, or a rope, or may be constructed by combining them. That is, the driving means W1 and W2 may extend in one direction and be formed into various flexible shapes, and may be made of various materials such as a metal or an alloy material, a reinforcing fiber, or the like.

5, in this embodiment, the driving means W1 and W2 include a first driving means W1 and a second driving means W2. First, the first driving means W1 has its both ends And is fixed to a lower portion of the winch assembly 320 and the second post 330 and is turned at an exit edge of the first inner space of the first post 310 to extend to a lower portion of the second post 330.

That is, the first driving unit W1 extends upward from one end connected to the winch assembly 320, extends downward at an exit of the first inner space of the first post 310, And is fixed to the lower portion of the second post 330. Reference numeral 338 denotes a first fixed end to which the first driving means W1 is fixed to the second post 330. [ Accordingly, when the winch assembly 320 is operated in the winding direction, the entire length of the first driving means W1 is gradually reduced, so that the second post 330 is moved along the first driving means W1 As shown in FIG. At this time, since the first post 310 is in a fixed state, the height formed by the first post 310 and the second post 330 increases.

The second driving means W2 is fixed to one side of the first post 310 and the lower side of the third post 350 while the opposite ends of the second driving means W2 are fixed to the outlet of the second inner space of the second post 330 And extends to the lower portion of the third post 350 while changing its direction at the edge. That is, the second driving means W2 is connected to the first post 310 fixed at one end 380 and the other end is connected to the first post 310 and the second post 330, 3 post 350. Reference numeral 358 denotes a second fixed end to which the second driving means W2 is fixed to the third post 350. [

Accordingly, when the winch assembly 320 is wound and the second post 330 is relatively moved upward relative to the first post 310, the second post 330 can move the second driving unit W2 Drag and rise together. This is because the middle portion of the second driving means W2 extends downward at the exit edge of the second inner space of the second post 330 so that the second driving means W2 can move in the second post 330, And one end 380 of the second driving means W2 is fixed to the first post 310 so that the other end of the second driving means W2 is raised together with the second post 330 will be.

Accordingly, when the winch assembly 320 is operated in the winding direction to raise the second post 330, the second driving means W2 rises together with the second post 330, The third post 350 to which the other end of the means W2 is connected is moved upward with reference to the drawing. The third post 350 moves in a direction further projecting from the second post 330 and consequently the height formed by the first post 310, the second post 330 and the third post 350 .

At this time, a first pulley P1 is provided at the exit edge of the first inner space so that the first driving means W1 extends in the direction of the first pulley P1, A second pulley P2 is provided at the exit edge of the second pulley P2 so that the second driving means W2 is changed in direction with respect to the second pulley P2. Since the first pulley P1 and the second pulley P2 are rotatable, the first and second pulleys P1 and P2 do not generate a large frictional force in the process of pulling the first and second pulleys W1 and W2, .

On the other hand, gap maintaining / adjusting means (R1 to R3) are provided between the plurality of posts (300). The gap maintaining / adjusting means (R1 to R3) maintains a predetermined gap between the plurality of posts (300), thereby reducing the contact area during the relative movement of the plurality of posts (300) While preventing the post from rising smoothly due to the inclination of one of the plurality of posts 300 at the same time.

5 to 7, the interval maintaining / adjusting means R1 to R3 include a first interval maintaining / adjusting means R1 provided in the first post 310 and a second interval maintaining / adjusting means R1 provided in the second post 330 A third space maintaining / adjusting means R3 provided in the third post 350, and a third space maintaining / adjusting means R3 provided in the third post 350. [ In other words, each of the posts may be provided with spacing maintaining means R1 to R3. The first spacing and adjusting means R1 may protrude from the first post 310 toward the second post 330, And the second gap maintaining and adjusting means R2 may protrude from the second post 330 toward the first post 310 or from the second post 330 to the third post 330 350) (see FIG. 7). And the third space maintaining / adjusting means R3 protrude from the third post 350 toward the second post 330. [

7 and 9, the gap maintaining / adjusting means R1 to R3 may be formed of a roller module so that the plurality of posts 300 can be brought into rolling contact with each other during the relative movement. The roller module is constituted by a plurality of fastening means such as wheels and bolts and comes into rolling contact with the outer or inner surface of the post.

Alternatively, as shown in FIG. 10, the interval maintaining / adjusting means R1 to R3 may be configured as a block module. The block module includes a block spacer R1a provided between a plurality of posts 300 and a fastener R1b for adjusting the degree of protrusion of the block spacer R1a. That is, the block module is not a rolling contact structure but is made of a material having self-lubricating properties such as NYLON, polyacetal (POM), and polyethylene (PE) to maintain and adjust the gap between the posts Avoid direct friction between the posts.

Since the block module can adjust the degree of protrusion of the block spacer R1a through the fastener Rlb, it is possible to more finely adjust the operator in the actual installation process of the vehicle display device 100, The generated error can be compensated to some extent.

11A shows a state in which the degree of protrusion of the block spacer R1a is adjusted through the fastener RIb. In FIG. 11A, the block spacers R1a and R2a are disposed on the second post 330 and the third The block spacers R1a and R2a are in close contact with the outer surfaces of the second and third posts 330 and 350, respectively, Is shown.

Meanwhile, a display panel 500 is provided on the posts that are relatively moved with the posts having the winch assembly 320 among the plurality of posts 300. The display panel 500 is a part that substantially displays a directional marker or the like. In this embodiment, the display panel 500 is separated from the fastening bracket 390 of the third post 350 among the plurality of posts 300 .

Hereinafter, the installation / use process of the height-adjustable vehicle display device according to the present invention will be described in detail with reference to the drawings.

First, the vehicle display device 100 may be fixed to the vehicle. To do so, the operator sets the vehicle display device 100 behind the loading space of the vehicle 1, and then uses the fixing bracket of the first post 310 Thereby fixing the vehicle display device 100 to the rear of the vehicle 1 in a loop. At the same time, the vehicle display device 100 is supported on the floor of the vehicle by the base plate 200 under the display device 100 for a vehicle. That is, as described above, the plurality of posts 300 are stably mounted on the floor of the vehicle while a large area of the base plate 200 fixed through welding with the first posts 310 is stably mounted on the mounting assembly 700, The vehicle can be fixed firmly to the vehicle.

In this state, the worker uses the fastening bracket 390 to install the display panel 500 on the display device 100 for a vehicle. Of course, the display device 100 for a vehicle may be mounted on the vehicle while the display panel 500 is installed on the display device 100 for a vehicle. This state is shown in Fig. 12 (a). For convenience of reference, in FIG. 12, the display panel 500 and the mounting assembly 700 are omitted.

After the vehicle display apparatus 100 is installed, the display panel 500 is raised to a proper height. In order to heighten the height of the display panel 500, the operator rotates the handle 321 of the winch assembly 320 .

More precisely, when the operator rotates the handle 321 clockwise (in the direction of arrow 1) as shown in Fig. 12 (a), the first driving means W1 is pulled Since the first driving means W1 is wound and the other end of the first driving means W1 is fixed to the first fixed end 338 of the second post 330, And protrudes from the post 310 to move upward (arrow ③ direction). Such a state is shown in Fig. 12 (b).

At the same time, the third post 350 protrudes from the second post 330, which is connected to the second fixed end 358, which is the other end of the third post 350, at the other end of the second driving means W2 This is because the second posts 330 are pulled together in the ascending process.

More precisely, when the winch assembly 320 is wound and the second post 330 is relatively moved upward relative to the first post 310, the second post 330 is moved to the second driving means W2, And then rise together. This is because the middle portion of the second driving means W2 extends downward with respect to the second pulley P2 of the second post 330 so that the second driving means W2 can move in the second post 330, As shown in FIG.

One end 380 of the second driving means W2 is fixed to the first post 310 and the other end of the second driving means W2 is fixed to the second fixing end 370 of the third post 350. [ The third post 350 is lifted along the second driving means W and protrudes from the second post 330 because the third post 350 is fixed to the second post 358. This state is shown in Fig. 12 (c).

When the winch assembly 320 is operated in the winding direction and the second post 330 is lifted up, the second driving means W2 rises together with the second post 330 (in the direction of arrow 4) The third post 350 connected to the other end of the second driving means W2 moves upward with reference to the drawing. The third post 350 moves in a direction further projecting from the second post 330 and consequently the height formed by the first post 310, the second post 330 and the third post 350 .

That is, when the operator rotates the handle 321 of the winch assembly 320, the second post 330 and the third post 350 simultaneously protrude at the same time, so that the overall height of the vehicle display device 100 increases at a high speed do.

Meanwhile, in the present invention, since the space maintaining / adjusting means R1 to R3 are provided between the plurality of posts 300, the posts are spaced apart from each other by a predetermined distance in the course of relative movement of the plurality of posts 300 So that it is possible to prevent the post from being smoothly raised or lowered by tilting any one of the plurality of posts 300. In addition, since the frictional force is reduced, The height can be adjusted.

In particular, the operator can finely adjust the degree of protrusion of the block spacer (R1a) of the block module, which is the interval maintaining / controlling means (R1 to R3), and thereby, depending on the weight or shape of the display panel (500) Or the errors generated during the design / manufacturing process can be reduced.

By increasing the height of the vehicle display device 100 as described above, the operator can secure visibility for a desired distance. After use, the winch assembly 320 can be wound in the opposite direction to store the display device 100 for a vehicle.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. That is, within the scope of the present invention, all of the components may be selectively coupled to one or more of them.
