The present invention relates to a speed indicator lamp installed in a large truck, and more particularly, to a speed indicator lamp having a mounting structure that can be integrated into the lamp base more easily integrated.

Typically, a large truck such as a truck having a load of about 4.5 tons is provided with a speed indicator lamp that lights up according to the speed of the vehicle in the center of the driver's roof as shown in FIGS. 1 and 2. That is, the speed indicator lamp is composed of three lamps, the green light 50 on the left and right sides indicating the speed of the vehicle, respectively, and the red light 41 on the center. When the vehicle reaches a certain speed, one green light 50 is turned on, and when the speed is higher, the left and right green lights are turned on at the same time. Call attention to the vehicle.

Referring to FIG. 3, a flat cross-sectional view of a conventional speed indicator lamp with one side omitted is shown, while the central red light and the other green light are somewhat different from the green light on the side due to differences in shape. It may have a different configuration, but since the difference is almost the same in structure, the description thereof is omitted in the present specification for clarity. As shown in FIG. 3, the conventional speed indicator lamp is composed of three lenses and three reflectors, respectively. The reflector 11 of one green light is fitted with a light bulb 12 at a central portion thereof, and a multifocal region is formed around the light bulb 12.

One side lamp, that is, the edge of the reflector 11 of green light is formed in the lens coupling groove 15, the lens 13 is inserted into the lens coupling groove 15 of the reflector 11 along the edge. 13a is formed, and the insertion portion 13a is fitted into the coupling groove 15 so as to be coupled to the reflecting mirror 11 and fixed. In addition, the reflector 11 has a mounting bracket 19 on the outside of one lens coupling groove 15, and is fixed to the lamp base 1 by bolts 14.

4 is a cross-sectional view taken along the line IV-IV of FIG. 3, wherein the lens coupling groove 15 of the reflector 11 of the rust lamp is adjacent to the mounting bracket 16a of the central reflector 11 of the red light. Instead, a protruding force is formed to contact the base 1 and the base 1 ', and the mounting bracket 16a of the central red light is fixed to the base 1 by bolts 20.

FIG. 5 is a cross-sectional view taken along the line IV-IV of FIG. 3 and schematically shows in cross section a portion where the green light bulb 12 is fitted. As shown in FIG. 5, the lower part of the base 1 is fixed to the roof of the vehicle through a protective device 3 provided on the roof of the vehicle, and inserted into lens coupling grooves formed at upper and lower edges of the reflector 11. The insert is shown.

However, since the mounting structure of the conventional speed indicator lamp has a separate reflector and a lens for each lamp, the assembly process requires assembling work as much as the number of parts. As can be seen, since the base is connected to the roof of the vehicle at both sides of the lamp, and the center part of the lamp is separated from the roof of the vehicle, the base tremble when driving the vehicle, resulting in noise from bumping into the roof. And not only noise due to the resistance of the air can be generated, but also has the disadvantage that the durability of itself is lowered.

In addition, the conventional speed indicator lamp as described above has the drawback that the installation of the speed indicator lamp on the base is complicated because fastening means such as bolts are used to fix each reflector to the base.

Accordingly, an object of the present invention is to provide a speed indicator lamp having a lens structure integrated with an integrated reflector, more securely fixed to a base, and a mounting structure that is simply installed on the base.

In order to achieve this object, the speed indicator lamp mounting structure according to the present invention, in the speed indicator lamp of a large truck, a plurality of mounting brackets each having a through hole attached to the inside and a plurality of bolt through A base having a ball; A reflecting mirror installed inside the rear portion and having a plurality of pivot pins penetrating the holes of the bracket, a plurality of lens fixing portions formed opposite the pivot pins, and holes corresponding to the bolt through holes at both sides; And a lens assembly having a plurality of inserting portions inserted into the lens fixing portion of the reflecting mirror and a through hole coinciding with the bolt through hole of the base and the reflecting hole of the reflecting mirror.

Meanwhile, the lower edge of the base may be fixed to the roof of the vehicle through the protector.

In the speed indicator lamp of the present invention having the above structure, the pivot pin and the hole of the reflector are matched to the bolt through hole and the hole of the mounting bracket of the base, and the insertion part and the through hole of the lens assembly are the lens fixing part of the reflector assembly and Matched to the holes, they are assembled together by fastening and fixing the pivot pins and holes with a grommet made of elastic, high-friction material such as rubber, and the lower edge of the base contacts the roof of the vehicle, making the lamp more It is securely fixed to the roof of the vehicle.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Of the components of the present invention to be described later, the same reference numerals are used for the same portions as those of the prior art.

6 is a cross-sectional view of the speed indicator lamp according to the present invention. The base 1 is provided with a plurality of brackets 33 on the inner central portion, which fixes a plurality of pivot pins 31 (only one is shown for the sake of clarity) of the reflector 21 on the inner side, and on both sides thereof. A plurality of bolt through holes 35 are formed. When the pivot pin 31 of the reflector 21 projects through the bracket, the grommet 32 is fitted to the end of the pivot pin so that the pivot pin 31 is fixed to the bracket of the base so that the reflector 21 It is fixed to (1). In addition, the rectangular reflector 21 has three concave reflecting portions formed integrally to reflect all three lamps when three lamps, i.e., the left and right green lights and the central red light are turned on.

In addition, a lens coupling groove 24 is formed along the edge of the reflector 21 on the front surface of the reflector 21 opposite the pivot pin 31, and bolts of the bracket 34 connected to the base 1 are formed at both ends. It has a hole coinciding with the through hole 35 and is fixed to the bracket 34 of the base 1 by the bolt 40.

On the other hand, the rectangular lens assembly 23 of the same size as the reflector 21 has a convex shape forward, a plurality of inserts 37 is fixed to the lens coupling groove 24 of the reflector 21 on the back side. Is formed, and both sides have a concave groove portion 38 in which a plurality of holes are formed to coincide with the holes of the reflector 21. Insertion portion 37 is accommodated in the lens coupling groove 24 and is elastically gripped by the lens coupling groove 24, thereby preventing movement to the left and right.

7 and 8 are cross-sectional views taken along the lines VII-VII and VIII-VIII of FIG. 6, wherein the reflector 21 is supported by the grommet 32 through the pivot pin 31 and the bracket 34 by the base. The state fixed to (1) is shown more reliably. In this figure, the upper and lower protruding edges 23a and 23b of the lens assembly 23 fit into the lens engaging groove 24 of the reflector 21. The lower edge of the base 1 is firmly fixed to the roof 2 of the vehicle along the guard 30.

As can be seen from the above description, the pivot pin 31 connected to the reflector 21 protrudes through the bracket 33 and the grommet 32 is fitted at the end thereof so that the reflector 21 is When the lens assembly 23 is assembled onto the reflector 21 and then fixed to the base 1, the bracket 40 fixed through the bolt 40 penetrates the hole formed at both ends of the base, the reflector and the lens assembly. By being fixed to 34, the speed indicator lamp according to the present invention is fixed to the vehicle as a completed assembly.

Although the method of coupling the reflector to the base in the embodiment described above consists of pivot pin and grommet coupling, it is obvious that the two components can be combined in other ways as well.

Since the speed indicator lamp according to the present invention has the structure as described above, three lamps can be assembled at the same time, thereby reducing the manufacturing cost of the lamp and reducing the manufacturing cost, and by assembling the pivot pin and grommet. It is easy to remove the gap between the base and the roof of the vehicle can be prevented from the generation of noise due to the gap and the degradation of durability due to air resistance.
