Description

Headlamp multi-aming device

The present invention relates to a headlamp multi-aming device, especially when the vehicle turns left or right at night or when driving uphill or downhill, the focus of the headlamp can be automatically adjusted in the left and right or up and down directions. 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 becomes far from the light, and when the road is going downhill, the focus is narrowed and close to the contrary to the above. 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 the left and right directions or the up and down directions, thereby making it easy to secure a night vision and providing a headlamp multi-aming device that prevents the occurrence of a traffic accident.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention, the same reference numerals will be used for the same parts throughout the drawings.

1, there is shown a circuit diagram showing the overall circuit configuration of a headlamp multi-aming apparatus according to the present invention; Figure 2 shows a cross-sectional view showing a support structure and the aid structure of the headlamp multi-aming device according to the present invention.

The headlamp multi-aming device 100 according to the present invention is a tilt detection switch 108, a left turn detection switch 110, a right turn detection switch 112, a tilt detection conversion controller 114, a rotation detection conversion controller ( 116), a vertical adjustment bidirectional step motor 118, and a left and right adjustment bidirectional step motor 120.

The inclination detection switch 108 is fixed to the vehicle body in a horizontal manner with the ground, and includes a rectangular housing 150. Electrical input and output contacts 152 are attached to the inner surfaces of the front wall and the rear wall of the housing 150, and the central weight 148 having a suitable size and weight is movable on the inner surface of the upper wall of the housing 150. Is fixed. One end of the spring 154 is fixed to the lower end of the central weight 148, and the other end of the spring 154 is fixed to the lower wall of the housing 150. The spring 154 has an appropriate length and elasticity. When the vehicle is inclined backward or forward when the vehicle is going up or down a hill, the housing 150 fixed to the vehicle body is also inclined at the same angle as the vehicle body.

At this time, the center weight 148 inside the inclination detecting switch 108 is, of course, regardless of the inclination angle of the housing 150, depending on the support force of the spring 154 fixed to the lower end thereof. Tilting may be acceptable, but will generally remain perpendicular to the ground. Accordingly, the sidewalls of the inclined housing 150 and the central weight 148 vertically come into contact with each other. Therefore, as the center weight 148 made of a conductor contacts the electrical contact 152, a power source is connected to form a circuit. Since the electrical contacts 152 attached to the front wall and the rear wall inner surface of the housing 150 of the inclination detection switch 108 are attached with a cushion spring having some elasticity between the housing 150, the center weight In contact with 148, the vehicle maintains continuous contact even with the shaking of the vehicle. The spring 154 at the lower end of the center weight 148 prevents the operation of the center weight 148 under driving conditions such as when the vehicle is traveling on a flat road or a slope below a predetermined value, or when the vehicle is swung, suddenly started, or suddenly braked. Or the center weight 148 to function.

The left turn detection switch 110 or the right turn detection switch 112 is mounted at two front and rear directions of the knuckle 142 on the front axle 140, respectively. Each switch 110, 112 includes a cylinder 156 having a suitable circular shape, and a plurality of electrical input and output electrical contacts 144 and insulators 158 are alternately arranged on the inner surface of the cylinder 156. . All of these electrical contacts 144 are sequentially connected to a resistance of a certain intensity. A piston 162 is disposed on the inner surface of the cylinder 156 so as to reciprocate, and one end of the piston rod 164 is fixed to the piston 162 and the other end of the piston rod 164 passes through the cylinder 156. To protrude to the outside. The roller 146 is rotatably fixed to the other end of the piston rod 164 projecting outward. The return spring 160 having an appropriate length and elasticity is provided inside the cylinder 156 to pull the piston 162 in one direction.

When the steering wheel of the vehicle is rotated to the left or the right, the front knuckle 142 that is linked to the steering wheel is rotated together, the portion of the knuckle 142 presses the roller 146 portion of the rotation detection switch (110, 112). When the vehicle is rotated at a rotation angle of a predetermined value or more, the piston rod 164 is pushed and the electric movable contact is in contact with the fixed contacts 144 in the cylinder 156 to form an electric circuit. Initially, the resistance is the largest, and as the rotation angle increases, the resistance becomes smaller and the electric power is energized more and more, and while the rotation on one side is activated, that is, while the switch on the one side is in operation, the switch on the other side does nothing. In addition, the operation of the switch is stopped even if the vehicle is going straight or the rotation angle is below a certain value.

Each inclination detection switch 108 and rotation detection switches 110 and 112 are connected to the inclination detection conversion controller 114 and the rotation detection conversion controller 116, respectively, each inclination detection conversion controller 114 and rotation The up and down adjustment bidirectional step motor 118 and the left and right adjustment bidirectional step motor 120 are connected to the sensing controller 116, respectively. The inclination detection conversion controller 114, when the power is input from the front or rear of the inclination detection switch 108 over a predetermined time, respectively, the internal contact is in contact with the vertical adjustment bidirectional step motor 118 When the power connected directly to the second ignition key 104 is energized, the rotation sensing conversion controller 116 receives power when the power indicating that rotation is generated left or right from the rotation sensing switches 110 and 112 is input. The direct power of the ignition key 2 stage 104 is energized to the left and right bidirectional step motor 120 according to the direction and the intensity of. One of the other important functions of the conversion controllers 118 and 120 is that when the power input from the respective switches 108, 110 and 112 is cut off, the contact points of the internal contacts are reversed so that the power of the ignition key 2 stage 104 is turned off. Inputted to the opposite wiring, the amount of power initially supplied to the bidirectional step motors 118 and 120 is supplied to the opposite wiring, and the step motors 118 and 120 are rotated in the opposite directions to return to their original positions.

The bidirectional step motors 118 and 120 remain fixedly mounted to the headlamp housing 134. After the headlamp switch 106 is turned on, the vehicle is rotated or tilted so that the power of the battery 102 is supplied to the bidirectional step motors 118 and 120 and the bidirectional step motors 118 and 120 are rotated in the right direction according to the direction of the input power. When driven or driven in the left turn direction, the sleeve 122 is also rotated at the same time, and the aming rod 124 coupled to the thread inside the sleeve 122 does not rotate together but is linearly moved forward and backward along the thread. . Accordingly, one side of the reflector 136 connected to the other end of the aiming rod 124 via the ball joint 126 is pushed or pulled to change the focusing direction by changing the irradiation direction of the headlamp bulb 138. .

Above and below the headlamp housing 134, a cylinder 166 is provided to pivot the retainer 136 to the headlamp housing 134, and a piston 168 reciprocates inside the cylinder 166. It is movably excreted. One end of the support rod 130 is fixed to the piston 168, and the other end of the support rod 130 protrudes outward toward the reflector 136 through the cylinder 166.
