Description

Headlamp multi-aming device

The present invention relates to a headlamp aiming device, in particular, so that the headlamp focus can be automatically adjusted in the left, right, up and down directions, especially when the vehicle turns left or right or drives uphill or downhill at night. Therefore, the present invention relates to a head lamp multi-aiming device that facilitates securing a night vision and prevents the occurrence of a traffic accident.

The headlamps are also referred to as headlights as the luminaires that function the main way at night. The focus of the headlamps is regulated by the laws of each country so that a certain distance can be projected at a certain height, width, and brightness, and the focus of the headlamps mounted on the front of the body is satisfied to satisfy these regulations. Ming will be done. As for the head lamp's amming method, the direction of the head lamp as a whole may be changed by manually turning the amming screw attached to the head lamp itself or the direction of the reflector provided inside the head lamp housing. Used.

The method of controlling the reflector among the aiming headlamps is somewhat complicated in structure and has some problems in flow and durability, but in order to satisfy legislation established in a specific country and due to the aiming Since there is no step or gap between the vehicle body, it is a situation that is favored in recent years. In the method of controlling the reflector and aiming the focus, the reflector is mounted on the support pin and the adjusting screw provided on the headlamp housing, and the transparent glass cover is integrally mounted on the housing in front of the reflector. The bulb is fixed to the reflector in a detachable manner. Arbitrary lines are drawn in the vertical direction and the left and right diagonal direction around the bulb, and the adjusting screw is mounted at two places where these four lines meet, and the supporting pins are installed at the other two places. Rotation of either the adjusting screw provided downward or the adjusting screw provided laterally causes the reflector itself to move forward or backward while twisting in a diagonal direction, thereby moving the focal direction of the bulb to the left and right or up and down The focus can be aimed in the direction.

However, in the headlamp amming device according to the prior art structured as described above, since the amming work is performed while the vehicle is stopped and in a horizontal plane, the focal point is unstable in accordance with the change in attitude of the vehicle which appears during the driving of the vehicle. It may be irradiated in the direction. In other words, when the vehicle turns left or right, the faster the vehicle is, the narrower the field of view for the driver to recognize the situation in the dark. In addition, the situation of the part that has already rotated is not important, but the visibility of the coming situation becomes more important. The focus of the headlamp is always kept in a fixed position, and unfortunately, the driver or pedestrian cannot be seen. Or it acts as a threat to the safety of all the vehicles running on the other side. In addition, when the vehicle is going uphill, the focal length is far from the light, and when the road is going downhill, the focus is narrowed to the contrary, and the headlamp generated when driving on such a slope changes according to the change of focus. The problem that occurs may be the same problem as the risk that occurs during rotation as described above.

In recent years, most passenger cars in Europe are equipped with a headlamp leveling device that manually adjusts the height of the headlamps.This device focuses on the headlamps manually in two to three stages as the vehicle moves up and down hillsides. As a device for dimming, it is used as a means for passively solving the problem of driving on a slope among the problems inherent in the above-mentioned headlamp. The device is equipped with an appropriate gear to the aming screw behind the headlamp and an electric motor shaft fixed gear that meshes with the gear.The motor is operated by a switch to rotate the gear by a certain amount to adjust the focus of the aiming screw. Use a way to change the However, in this manner, there was an inconvenience of manually operating the switch whenever necessary.

The present invention was created to solve the problems inherent in the headlamp amming device according to the prior art as described above, the object of the present invention is to make a vehicle turn left or right turn or drive uphill or downhill at night In this case, the focus of the headlamp can be automatically adjusted in left, right, up and down directions, or in a forward and backward direction, thereby making it easy to secure a night vision and preventing the occurrence of a traffic accident.
