FIG. 1 illustrates a vehicle to which an angle adjustable vehicle light emitting device according to the present invention is applied.

As described above, the angle-adjustable vehicular light projecting device (hereinafter referred to as 'light projecting device') according to the present invention illuminates light in a state where it is installed on the vehicle 1 to illuminate a certain range of places. In this embodiment, And is used as a vehicular light emitting device for illuminating a work / work site where nighttime or light quantity is insufficient by using illumination units 510. At this time, since the height of the light projecting means 500 of the vehicle light projecting apparatus according to the present invention can be adjusted, light can be irradiated to a relatively long distance. FIG. 2 shows an increased height of the light projecting apparatus for a vehicle . The specific structure related to the height adjustment will be described below.

First, the appearance and skeleton of the vehicular light emitting device 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 light emitting device.

The plurality of posts 300, the winch assembly 320 and the driving means W1 and W2 to be described below constitute height adjusting means (not designated) to vary the overall height of the vehicle light emitting device .

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. Although not shown precisely, the mounting assembly 700 is comprised of a vertical frame and a horizontal frame, through which the mounting assembly 700 can engage the first post 310 with the vehicle.

In the vehicle light emitting device according to the present invention, the plurality of posts 300 that can be overlapped with each other may be composed of two or three or more, in this embodiment, 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. Hereinafter, the first post 310 fixedly installed and the second post 330 and the third post 350 moved relative to each other will be referred to as a relative movement post.

The winch assembly 320 is installed on the outermost first post 310 fixedly installed. The winch assembly 320 winds or unwinds the driving means W1 and W2 using a rotational force by a manual or motor to provide driving force for adjusting the height of the vehicle light emitting device.

More specifically, as shown in FIG. 4, 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 vehicular light emitting device is maintained as it is.

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.

7, 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 relatively movable with respect to the second post 330, and a light emitting unit 500 described later is coupled to the outer portion.

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 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.

4 and 5, in this embodiment, the driving means W1 and W2 include a first driving means W1 and a second driving means W2, And both ends thereof are fixed to the lower portions of the winch assembly 320 and the second posts 330 and are turned at the exit edges of the first inner spaces of the first posts 310 to extend to the lower portion of the second posts 330 do.

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) adjusts a predetermined gap between the plurality of posts (300) and is maintained in a regulated state. In the process of relatively moving the plurality of posts (300) Thereby reducing the frictional force by reducing the contact area, and at the same time, preventing any phenomenon that one of the plurality of posts 300 is tilted at the same time, thereby preventing the post from being smoothly moved up and down.

Further, the operator can appropriately adjust the interval between the plurality of posts 300 by operating the interval maintaining / controlling means (R1 to R3), and accordingly, the weight of the relatively large light emitting means (500) It is possible to correct that the interval between the post 500 and the post 500 differs from the initial setting.

8 and 9, the gap maintaining / adjusting means R1 to R3 include a first gap maintaining / adjusting means R1 provided in the first post 310 and a second gap 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 / regulating means R2 may protrude from the second post 330 toward the first post 310 (see the lower portion of FIG. 4) or may extend from the second post 330 to the third post 350) (see FIG. 6). And the third space maintaining / adjusting means R3 protrude from the third post 350 toward the second post 330. [

Meanwhile, as shown in FIG. 6, the gap maintaining / adjusting means R1 to R3 are 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 FIGS. 8 and 9, the interval maintaining / adjusting means R1 to R3 may be formed of 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 light projector, To compensate for some extent, and also to compensate for the widening or breaking of the post during use.

9A shows a state in which the degree of protrusion of the block spacer R1a is adjusted through the fastener RIb. In FIG. 9A, the block spacers R1a and R2a are formed in the second post 330 and the third And 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, among the plurality of posts 300, the third post 350 includes the light emitting means 500 among the relative movement posts 330 and 350 that are moved relative to the fixing post 310 having the winch assembly 320 . The light projecting unit 500 irradiates light through the illuminating unit 510. In this embodiment, a total of four illuminating units 510 are provided. The illumination units 510 are connected to each other by a connection frame 515 and are installed symmetrically with respect to the angle adjusting unit 600 to be described below. More specifically, the illumination unit 510 includes two light sources having different heights on the left side of the angle adjusting unit 600, and two light sources having different heights on the right side. A commercial power source or a generator may be connected to the illumination unit 510 to supply power.

As shown in FIG. 3, the connection frame 515 is composed of a connection shaft 520 and a vertical frame 530. The connection shaft 520 extends in the left-right direction with reference to the drawing and is connected to the tilt shaft 525 to be described below and rotates together. The upper and lower frames 530 are coupled to the connecting shaft 520 in the vertical direction with reference to the drawing, and the lighting unit 510 is substantially installed.

At this time, the connection shaft 520 is installed to cross the right and left sides of the angle adjusting means 600 and is rotated together with the tilt shaft 525 to tilt the lighting unit 510. The connection shaft 520 may be part of the tilt shaft 525 or may be coupled to the tilt shaft 525 as a separate member from the tilt shaft 525.

An angle adjusting means 600 is connected to the light projecting means 500. The angle adjusting means 600 enables rotation of the light emitting means 500. In the present invention, the light emitting means 500 is rotated in the left-right direction (arrows (1) in FIG. 3) with respect to the fixed first post 310 (Hereinafter referred to as " tilt ") and up-and-down rotation (hereinafter referred to as " swivel " The angle adjusting means 600 is detachably coupled to the third post 350 among the plurality of posts 300.

As shown in FIG. 11, the angle adjusting means 600 forms the skeleton of the housing 612. A first installation space S1 is formed outside the housing 612 and a first driving source M1 and a second driving source M2 are provided and a circuit board for controlling the operation of the two driving sources M1, (Not shown). The circuit board controls the two driving sources M1 and M2 so that the power supply line for supplying the power to the lighting unit 510 is not twisted in the course of the rotation of the lighting unit 510, And performs swivel and tilt functions within the range.

The first driving source M1 and the second driving source M2 are for tilting and swiveling the light emitting means 500. In this embodiment, the first driving source M1 and the second driving source M2 are driven by an electric motor . Of course, the first driving source M1 and the second driving source M2 are not limited to the electric motor, and may be operated by hydraulic pressure or air pressure.

Although not shown, a cable for power supply is connected to the first driving source M1 and the second driving source M2, and the first driving source M1 and the second driving source M2 are connected to each other via a separately installed switch or a remote controller. Power can be selectively applied. At this time, the direction of the rotational force provided by the first driving source (M1) and the second driving source (M2) can be changed through the operation of the switch or the remote controller, so that the light emitting device can be swiveled and tilted in both directions.

At this time, the first driving source (M1) and the second driving source (M2) are installed in a direction parallel to the direction in which the light emitting means (500) emits light. That is, the first driving source M 1 and the second driving source M 2 are installed in a direction orthogonal to the direction in which the posts 300 extend, and at the same time, installed in a direction orthogonal to the direction in which the tilt shaft 525 extends do. This prevents the overall height of the vehicle light emitting device from being increased by the first driving source M1 and the second driving source M2 and also reduces the area occupied by the angle adjusting means 600 when viewed from the front where the light is irradiated .

In this embodiment, the first driving source M 1 and the second driving source M 2 are installed at different heights in the outer cover 610. More precisely, the first driving source M1 and the second driving source M2 are installed at different heights and spaced apart from each other in the left-right direction when viewed from the front. This is to prevent the gears installed in the second installation space S2 of the housing 612, which will be described later, from interfering with each other.

A tilt shaft 525 is extended across the outer cover 610 in the left and right direction and both ends of the tilt shaft 525 are connected to the connection shaft 520. As described above, the tilt axis 525 may be integral with the connection shaft 520 or may be a separate water assembly.

The second installation space S2 of the housing 612 is provided with tilt gear portions 631 and 635 which are operated by the first driving source M1 to tilt the light projecting means 500, And swivel gear portions 651 and 655 for swiveling the light projecting means 500 are provided. The outer cover 610 functions to protect the two driving sources M1 and M2 and the circuit board installed in the housing 612 from the outside through a waterproof and dustproof function and to make the appearance of the outer cover 610 beautiful.

The tilt gear portions 631 and 635 include a first driving gear 631 connected to the first driving source M1 and a first driven gear 635 coupled to the first driving gear 631. The first driving gear 631 is directly connected to the first driving source M1 and is rotated while one end of the rotating shaft 630 is rotated in a state of being supported by the housing 612.

The first driven gear 635 rotates in a direction perpendicular to the first drive gear 631 with the tilt axis 525 as a rotation axis, and as a result, the tilt axis 525 is rotated by the rotation axis of the first drive gear 631 And is rotated around a rotation axis orthogonal to the rotation axis 630. The first driving gear 631 and the first driven gear 635 are composed of a worm and a worm gear.

The swivel gear units 651 and 655 include a second driving gear 651 connected to the second driving source M2 and a second driven gear 655 interlocked with the second driving gear 651 . The second driving gear 635 is directly connected to the second driving source M2 and rotated, and one end of the rotating shaft 650 is rotated while being supported by the housing 612. [

The second driven gear 655 is relatively rotated with the second drive gear 651 about the swivel shaft 540. The second driven gear 655 and the swivel shaft 540 rotate relative to the post 300 As shown in Fig. The second driven gear 655 is not rotated substantially and the entire housing 612 and the outer cover 610 provided with the second drive gear 651 and the second drive gear 651 interlocked therewith rotate Swivel operation.

The swivel shaft 540 is provided in a direction perpendicular to the rotation axis of the second drive gear 651, that is, in a direction in which the post 300 extends, and the second drive gear 651 and the second driven gear 655) consists of a worm and a worm gear.

At this time, the first driven gear 635 and the second driven gear 655 have rotation axes orthogonal to each other, thereby preventing the first driven gear 635 and the second driven gear 655 from interfering with each other in the second installation space S2 of the housing 612 as much as possible, .

Hereinafter, a process of installing / using an angle-adjustable vehicular light emitting device according to the present invention will be described in detail with reference to the drawings.

First, the vehicle light emitting device can be fixed to the vehicle. A large area of the base plate 200 welded to the first post 310 is stably mounted on the floor of the vehicle, and at the same time, As shown in Fig.

In this state, the worker mounts the light projecting means 500 on the third post 350 of the above-mentioned vehicle light projecting device. Of course, the vehicle light emitting device may be installed in the vehicle with the light projecting means 500 first installed in the vehicle light projecting device. Such a state is shown in Fig.

After the vehicle light emitting device is installed, the work of increasing the light projecting means 500 to an appropriate height continues. In order to raise the height of the light projecting means 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. 10A, the first drive means W1 is pulled (in the direction of arrow 2) 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 and moves upward (arrow ③ direction). Such a state is shown in Fig. 10 (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 is shown in Fig. 10 (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 light emitting device is increased at a high speed.

When the overall height of the light emitting device is increased as described above, the height of the light emitting means 500 provided in the third post 350 increases together with the result that the light is irradiated by the illumination portion 510 of the light emitting means 500 The range and distance are increased.

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 any one of the plurality of posts 300 is tilted to prevent the post from being raised or lowered smoothly. Further, since the frictional force is reduced, the operator can adjust the height of the vehicle light emitting device with less force It is possible.

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, Or an error occurring in the design / manufacturing process or a gap generated during use can be reduced.

Next, a process of rotating the vehicular light emitting device according to the present invention will be described.

The operator can rotate the light emitting means 500 when it is desired to change the irradiation direction of the light irradiated by the illumination portion 510 of the vehicle light emitting device installed in the vehicle. When the operator operates the switch, power is applied to the first driving source M1 or the second driving source M2, and the first driving source M1 or the second driving source M2 operates.

When the first driving source M1 is operated, the tilt gear portions 631 and 635 are operated by the first driving source M1 to tilt the light emitting means 500. More precisely, the first driving gear 631 and the first driven gear 635 of the tilt gear portions 631 and 635 are interlocked with each other and the tilt shaft 525, which is the rotation axis of the first driven gear 635, Are rotated together to perform a tilting operation. Figs. 12 (a) and 12 (b) each show a tilted state in different directions.

On the other hand, when the second driving source M2 operates, the swivel gear units 651 and 655 operate by the second driving source M2. More precisely, when the second drive gear 651 of the swivel gear units 651 and 655 is rotated, the second driven gear 655 connected thereto is relatively rotated. At this time, since the second driven gear 655 is fixed to the third post 350 together with the swivel shaft 540, the second driving gear 651 is substantially rotated and the entire angle adjusting means 600 is rotated And swivel operation is performed. 13 (a) and 13 (b) show a state in which they are tilted in different directions.

As described above, even if the vehicle light emitting device is fixedly installed when the light emitting means 500 is tilted / swiveled, light can be irradiated to various positions by the illuminating portion 510 of the light emitting means 500, Or moving the vehicle. In addition, when the angle adjusting means 600 is operated together with the height adjusting means described above, both the direction and the distance in which the light is irradiated can be adjusted, thereby improving the operability.
