Description

Structure of head lamp being made up of 4-lamp for automobile}

The present invention relates to a structure of a quadruple headlamp for automobiles, and more particularly, to secure a means for accommodating an uplamp assembly in an integrated base holder of a downlamp assembly, thereby integrating the downlamp assembly and the uplamp assembly. By combining them, it is possible to reduce the number of parts and the number of assembly parts compared to the method of assembling the upper lamp assembly and the lower lamp assembly by using a separate base plate, thereby improving assembly performance and reducing costs. On the other hand, in terms of materials, by changing the existing plastic material to aluminum die-casting, relates to a four-lamp headlamp structure for automobiles that can increase the durability of the component due to the increased rigidity of the component.

In general, the headlamps for automobiles can adjust the irradiation angle of light up and down so as not to obstruct the view of the opposite driver, and recently, these adjustments are performed by using an upward lamp and a downward lamp.

Such headlamps are adapted to adjust the irradiation angle of the light up, down, left and right according to the state of the vehicle. This adjustment is called aming, and is usually provided with an aming means.

The adjustment method of the aiming means includes the initial aiming adjustment, i.e. after the headlamp is mounted on the vehicle body, and before use or during inspection, and the leveling adjustment, i. Each time there is an adjustment to correct it.

This initial aiming adjustment is usually done by an aming means by manual operation, and the leveling adjustment is made by a drive mechanism driven in part by remote operation.

For this reason, the adjustment mechanism is provided at two spaced apart points, and the drive mechanism for the leveling adjustment is installed at the adjustment point common to the adjustment point for initial initial adjustment of the irradiation angle in the up and down direction, and thus these manual adjustments. In many cases, the action adjusting mechanism and the leveling driving mechanism are integrated.

As shown in FIG. 2, a general structure of an automotive headlamp is shown. Here, reference numeral 1 denotes an amming apparatus, reference numeral 2 denotes a cylindrical movable body that is movably supported, and reference numeral 3 denotes a movable body. The vertical aiming rod, which is rotated in place in the hole of, denotes the reflector freely supported on the lamp housing, respectively.

When the rear end of the vertical aiming rod 3 is rotated, the nut 5 is driven by the vertical aiming rod 3 because the vertical aiming rod 3 is threaded into or out of the nut 5. The reflector 4 is rotated in the vertical direction because the movable body 2 is fixed, although it moves relatively in the front-rear direction.

This is the initial aiming adjustment in the vertical direction.

In addition, the left and right rotation is rotated while the horizontal aiming rod 6 is coupled to the nut portion 7 formed in the reflector 4 so that the horizontal aiming rod 6 is fixed to the housing. Rather, the left and right angles of the reflector 4 can be adjusted by pulling or pushing the nut part 7.

On the other hand, the head lamp is attached to each of the two lamps and one lamp is mounted on each of the left and right sides of the front part, so that the inner lamp functions as an upper lamp, the outer lamp functions as a downward lamp. There is a four-lamp lamp configured.

Figure 3 is an embodiment of the structure of a conventional four-lamp headlamps for automobiles.

Two lamps are mounted to the shroud panel 100 by respective pivot points 600, and the lamp shown on the right side of the drawing is an uplamp assembly 200 that emits light over a wide range of the front part at night driving of the vehicle. Since the driver widens the driver's field of view, the lamp shown on the left side is installed as the downward lamp assembly 300 so that the irradiation angle of the lamp is biased downward so as not to obstruct the vision of the oncoming vehicle driver from the front.

However, in the conventional dimming structure of the quadruple headlamps, each amming means 500 must be provided for each amming operation of the two lamps, resulting in an increase in the number of parts and causing a cost increase. In addition, there is a problem in that the number of work is increased because each of the two aiming work.

On the other hand, Figure 3 is an embodiment of the structure of a conventional four-lamp headlamps for automobiles.

The up ramp assembly 200 and the down ramp assembly 300 are assembled in a structure that is accommodated and mounted in the long hole 410 of the separate base plate 400, respectively, and adjusts the down ramp assembly 300 side. The upward lamp assembly 200 is also automatically adjusted to be adjusted.

In the above structure, it is possible to reduce costs by reducing the number of parts (aming means) for adjusting the irradiation angle, and to adjust the irradiation angle more quickly and easily, but additional base plates are additionally added. Since manufacturing and assembling together, the weight increases, and each lamp assembly needs to be assembled with the base plate, thereby increasing the probability of assembly scattering, thereby causing quality problems.

Accordingly, the present invention has been made in view of the above problems, and includes an integrated base holder in the down lamp assembly, and mounts the up lamp assembly on the base holder. By constructing the structure for dimming, the separate base plate can be deleted to reduce the number of assembly work, and the one-piece base holder can prevent the deformation of parts caused by the separate configuration, while the heat resistance of the material of the base holder The purpose of the present invention is to provide a structure of a four-lamp headlamp for automobiles that can improve the durability of parts by improving aluminum die casting.
