    High beam auto off of headlamps
    BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a head lamp of a vehicle lighting device, and more particularly, to a high beam auto-off device of a head lamp.
    In general, headlamps are also referred to as headlights as the main function of lighting the road ahead at night and require brightness to identify traffic obstacles at a distance of 100m ahead at night, but performance may vary by country. The criteria are different. The headlamp is provided with a headlamp aming device for adjusting the beam in the up, down, left, and right directions. In the above description, when the headlamp is adjusted upward, the high beam is referred to as a low beam.
    In general, look at the structure of the headlamp as follows.
    The headlamp includes a lens 1 and a reflector. The lens 1 is provided with a lamp 3 inside the reflector integrally fixed to the reflector, and a shield is provided by the rivet in front of the lamp 3. It is fixed to the inner surface of the reflector.
    A rim is attached to the outer surface of the lens 1, the rim is fixed to the housing bracket by a screw, another bracket is attached to the outer surface of the housing bracket, the other bracket is bent. A mounting plate is fixed to a portion of the body spaced apart from the bent portion, and a retainer is fitted into a hole formed in the mounting plate. The bent portion of the bracket and the mounting plate are coupled to each other by an aiming bolt extending through the retainer, and a spring is provided on an outer circumferential surface of the aiming bolt between the bracket and the mounting plate. The bracket and the mounting plate are pressurized in a direction away from each other.
    In addition, the headlamp wiring is usually divided into three wirings, which are divided into a high beam wiring 5, a low beam wiring 6, and a ground wiring 7.
    However, in the prior art, the driver may accidentally turn on the high beam and drive the vehicle. In this case, the driver may adversely affect the clock of the traveling vehicle and the front vehicle, causing an accident.
    Accordingly, an object of the present invention is to provide a high beam auto-off device for a headlamp that attaches a heat deformation switch to a wire for operating the high beam of the headlamp and automatically turns it off when the high beam is turned on for a predetermined time. It is.
    1 is a cross-sectional view of a headlamp according to the prior art.
    2 is a cross-sectional view of a high beam automatic off device for a headlamp according to the present invention.
    Explanation of symbols on the main parts of the drawings
    3: lamp 5: high beam wiring
    10 wax container 12 corrugated pipe
    14 elastic piece 16: bracket
    18: power pole plate 20: lamp pole plate
    30: thermal strain switch
    The present invention for achieving the above object is a high beam auto-off device of the headlamp has two pole plates separated by cutting a predetermined portion of the high beam wiring of the headlamp wiring, the end is located in the headlamp while the head A container encapsulating a volatilizable material according to the heat of the lamp, a corrugated pipe that can be stretched and contracted by the volatilized material, and the other end penetrates between the lamp electrode plate and the power electrode plate, and both ends are curved inwardly. A thermal deformation switch installed with an elastic piece for switching; Characterized in that is provided.
    By the above configuration, when the volatile material is expanded due to the heat generation of the lamp, the corrugated tube is extended to separate the elastic piece from the lamp electrode plate and the power electrode plate so that the high beam is turned off by disconnecting the electric current conducted to the high beam.
    Hereinafter, with reference to the accompanying Figure 2 will be described a preferred embodiment of a high beam auto-off of the headlamp according to the present invention.
    Figure 2 shows a preferred embodiment according to the present invention, Figure 1 is a cross-sectional view of the high beam automatic off device of the headlamp according to the invention, Figure 2 is a main part of the high beam automatic off device of the headlamp according to the present invention It is a cross section.
    As shown in FIG. 2, the high beam auto-off device for a headlamp according to the present invention includes a power pole plate 18 connected to a main power source of a high beam, and a lamp pole plate 20 connected to a lamp 3 located in the headlamp. ), A heat deformation switch 30 installed in the headlamp fixing case 2, and an elastic piece 16 for switching the heat deformation switch 30 and the positive electrode plates 18 and 20. have.
    The lamp electrode plate 20 is connected to the lamp 3 located in the head lamp in the high beam wiring 5 among the head lamp wires.
    The power plate 18 is connected to a power source in the high beam line 5 of the head lamp wires. In addition, the lamp electrode plate 20 and the power electrode plate 18 are installed at a slight interval, and the lamp electrode plate 20 and the power electrode plate 18 extend upward from the connector 4 of the headlamp. It is installed at 16.
    The heat deformation switch 30 has a wax container portion 10 formed therein so as to contain wax while being installed in the head lamp fixing case 2, and a central portion protruding outward of the head lamp fixing case 2. The corrugated pipe 12 is formed so that the portion of the corrugated pipe 12 when wax is expanded.
    The elastic piece 16 is installed on the other end of the thermal deformation switch 30 and serves to block the lamp electrode plate 20 and the power electrode plate 18 due to the expansion and contraction of the corrugated pipe 12. Both ends are bent toward the corrugated pipe 12 so that the switch can be turned on for a predetermined time to expand the wax.
    Referring to the operation of the high beam auto off device of the headlamp according to the embodiment of the present invention as described above are as follows.
    Since the wax is usually in a solid state, the portion of the corrugated pipe 12 is reduced so that the elastic piece 16 is in contact with the lamp electrode plate 20 and the power electrode plate 18. At this time, when the high beam is turned on due to a mistake of the driver's operation, the electric current is conducted in the order of the power source-power plate 18, the elastic piece 16, the lamp pole plate 20, and the lamp 3 to turn on the high beam. When the high beam is turned on, the lamp 3 becomes considerably heated in the lamp case due to the heat of the lamp 3. Due to the heat generation, the wax container part 10 inside the lamp case absorbs heat, and the corrugated pipe 12 extends as the wax in the wax container becomes a liquid. Due to the operation, although the corrugated pipe 12 is initially stretched, current is conducted due to the elasticity of the elastic piece 16. However, after a predetermined time, the elastic piece 16 is connected to the power electrode plate 18 and the lamp electrode plate. In this case, the high beam is turned off by breaking the current.
    As described above, the high beam auto-off device for the headlamp according to the present invention is automatically turned off after a certain time when the high beam is automatically turned off due to a driver's mistake of operation. It is off, so there is no need for a separate operation and the effect of not adversely affecting the watch of the crossing vehicle.
