The present invention relates to a device that automatically detects a headlight and turns the light on and off while the vehicle stops and runs, and in particular, it is possible to simply install a sensor without a deformation of the vehicle. The present invention relates to an automatic lighting control device designed to be able to eliminate unnecessary lighting of a drying lamp due to misoperation of a user during the day.

There are quite a few known forms of this prior art.

For example, Korea Utility Model Publication No. 357 (Notification No. 77-675), No. 447 (Notification No. 80-2103), No. 596 (Notification No. 83-637), No. 767 (Notification No. 756), 776 (notice 86-1266), and 872 (notice 87-2790) can be cited.

In this case, the headlight is automatically turned on by a combination of various sensors and switching circuits. Especially, the sensor is mounted on a rotating shaft, radiator, speed scale, etc. to detect its own operating state. It was used as a light sensor, a magnet sensor, and various other sensors.

However, in these cases, it was difficult to attach the vehicle's own means of detecting its own movement, and in the case of using a magnet or an optical sensor, when the car enters the muddy water or the mud, or when it rains, And moisture or the like is penetrated or deposited to be unable to exert its original function was to cause disadvantageous problems caused by this.

In addition, since the means for attaching such a sensor is complicated, this causes a practical deterioration of value, and the frequency of mechanical failure is likely to be frequent, and there are many disadvantageous problems in the management, handling, and maintenance.

On the other hand, the above-described techniques do not provide a separate safety condition for causing a reduction in the life of the lamp due to unnecessary flashing of the headlight when the user switches the headlight switch during the daytime operation. There was also an uncomfortable problem.

An object of the present invention is to improve the conventional problem as described above.

In particular, the present invention is a sensor that is easily mounted on a rotating shaft of a vehicle in the above-described device, and performs the automatic control of the headlamps and the related configuration with a circuit such that the lighting operation of the headlamps is unconditionally suppressed during the daytime. It is characterized by the automatic lighting control device of the headlamp.

This will be described in more detail below.

1 shows a circuit block diagram of the device according to the present invention.

Here, the soccer motion sensor 1 arranged on the horizontal axis of the wheel of the vehicle is connected to one input side of the gate output unit 3 through the signal detection rectifier 2 for signal differential and rectification.

In addition, the gate output section 3 is such that the photosensitive output section 7 generating a predetermined signal output from the photosensitive sensor 6 is connected to another input side thereof, and the output of the gate output section 3 is delayed. Through the circuit part 4 and the headlight driving part 5, it is the structure which automatically controls the headlight of a vehicle.

On the other hand, an embodiment of the apparatus according to the circuit block diagram is shown in FIG.

Here, the signal detecting rectifier 2 of the differential and rectifying circuits is connected to one end of the end gate 3a of the gate output unit 3 from the soccer copper sensor 1, which is a shaftless core core unit, and the other end of the optical sensor 6 The photosensitive output portion 7 of the transistor Q 'circuit is connected to the base input.

The output of the AND gate 3a, which is the gate output section 3, is passed to the headlight driving section 5 of the relay RY driving circuit through the delay circuit section 4 by the resistors R₁ and R₂ and the capacitor C. It is connected.

In addition, the soccer motion sensor 1 has an encoder film unit 13 which is directly condensed with a rotating shaft in a pair of semi-cylindrical sealed case members 11 as shown in FIGS. 3 and 4.

The film unit 13 has a recess portion 13b on the side of the bushing portion 13a which is condensed from the shaft member, and the centrifugal end portion 11a of the case member 11 is a bushing portion 13a on the recess portion 13b. An optical coupler unit 12 interposed between the main body 13b and the case member 11 through the encoder film unit 13 is installed on the upper side of the drawing. The thickened portion 11b is formed.

In addition, the encoder film unit 13 is condensed with the rotating shaft in the case member 11 so that the rotation is maintained with the rotation of the rotating shaft, and the case member 11 is the bushing part 13a of the film unit 13 side. Due to the lower weight portion (11b) is in place fixed to the surface contact in place.

In addition, the relative holding position of the case member 11 against the rotation of the encoder film unit 13 is a portion where the centrifugal end portion 11a and the bushing portion 13a side recess 13a from the case member 11 meet. In order to reduce the surface friction and to maintain the airtight from the outside can be configured through the oil-packing portion 15 or friction reducing means such as bearings.

Reference numeral 16 is an external connection wire, 17a, 17b is a case member 11, a coupling screw and nut 18a, 18b is a coupling screw and nut on the encoder film unit 13 and the bushing portion (13a) side, 19 is a rotating shaft.

The present invention of this configuration is as follows.

That is, in the automatic lighting control device of the headlamp of the present invention, the encoder film unit 13 is laid on the horizontal rotating shaft 1a of the vehicle using the coupling screw 18a and the nut 18b on the side of the bushing portion 13a. The pair of case members 11 are fixed to each other, and the semicircular flat portions are joined to each other to be assembled and fastened with a coupling screw 17a and a nut 17b.

At this time, the weight portion (11b) of the soccer motion sensor (1) is always sag downwards, the case member 11 according to this, the centrifugal bending end (11a) side of the film unit 13 to the free end It is in surface contact with the recessed part 13a of the side bushing part 13a, and is maintained in a fixed position on the said side.

In addition, the circumferential outer end of the film unit 13 is present between the optical sensor of the optical coupler unit 12.

When the vehicle is running in this state, the case member 11 of the soccer motion sensor 1 is fixedly maintained in a state where only the film unit 13 installed therein is rotated by the shaft 13 coupled to the bushing part 13a thereof. It is rotated together with the rotation axis of).

Therefore, in this case, the optical unit is light-blocked and conducts in a certain period by the film unit 13, so that a constant pulse is generated here.

The pulses generated in this way are differentiated into sharp trigger pulses in the signal detection rectifier 2 so that a plurality of trigger pulses according to the rotation become predetermined rectified waveforms as rectifiers, which are provided as one input logic of the gate output unit 3. It becomes.

At this time, another input side of the gate output unit 3 maintains logic 1 from the photosensitive output unit 7 operated by the solar sensor 6, so that a constant logic output is maintained at the gate output unit 3. It is done.

Here, the photosensitive output unit 7 maintains the conduction of the transistor Q 'in the state where the sunlight is maintained at a predetermined brightness, and the opposite operation is maintained when the sunlight is below the predetermined range. will be.

On the other hand, in the gate output section 3, a constant logic output is continuously maintained when the vehicle is traveling, whereby a constant charge is charged in the capacitor C on the delay circuit section 4 side, while the headlight driving section 5 side is charged. The inputs are provided to the bases of the transistors Q ₂ and Q ₃ which operate the relay RY, and are brought into a conducting state so that the power of the left and right headlamp circuits is connected.

As a result, the headlights are automatically turned on in addition to the artificial operating conditions at night when the vehicle is driven, thereby ensuring convenience.

In addition, when the vehicle needs to stop at the crosswalk, the horizontal axis of rotation of the vehicle is decelerated and stopped, so the output of the soccer movement sensor 1 does not have a pulse output, so that the output of the signal detection rectifier 2 or any logical output is not present. Does not exist.

Therefore, the gate output unit 3 does not have its pulse logic output, so the transistor of the headlight driving unit 5 side is turned off, and its relay RY is also kept off.

However, the off time of the transistors Q 2 and Q 3 may be delayed until a certain point at which the capacitor C of the delay circuit unit 4 is discharged through the resistor R 2.

On the other hand, during the day when the sunlight is kept above the predetermined range, the output logic of the light sensing output unit 7 on the side of the light sensing sensor 6 is maintained at 0, so that the headlight driving unit 5 The power of the headlight circuit is cut off because it is not in operation.

Therefore, even if the driver turns on the headlight by a misoperation by the manual operation switch, it is not turned on, thereby providing convenience.

In addition, the soccer motion sensor (1) is semi-cylindrical can be easily assembled to the rotating shaft does not cause any shape deformation for the vehicle itself, and to prevent the flow of the case member (11) circumferential surface and the upper side of the vehicle body A fixed position fixing means using a spring or the like may be provided between the fixing member and the fixing member.

In addition, since the sensor 1 and the circuit means can be given in a simple and simple form, it is possible to reduce the price of such an article, thereby ensuring the ease of maintenance and handling of the article and the convenience of handling.

The present invention is a device for automatically controlling the headlights of the vehicle, a sensor for detecting the driving state of the vehicle can be easily attached to the rotating shaft in relation to the running and stopping of the vehicle and the airtightness can be maintained well It is a drive shaft detection sensor of a shaftless encoder, and on the one hand, it is possible to automatically control the headlamps in relation to the solar detection means, which has the beneficial feature of improving the possibility of such an article and enhancing its practical value.
