Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cornering lamp device for use in a vehicle, and more particularly to a cornering lamp device that enables illumination when the vehicle is stopped.

[Conventional technology]

Cornering lamp devices generally turn on the headlights at the same time as the blinkers flash, thereby providing insufficient illumination in the left and right directions when turning left and right, and have been used relatively frequently.

[Problem that the invention attempts to solve]

However, in such conventional examples, the lights are not turned on unless the car is in progress, so the lights are not turned on at night, when the car is stopped, when the car is preparing to run, when loading or unloading luggage, etc. This created the inconvenience of having to prepare separate means.

[Purpose of invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a cornering lamp lighting device that can improve the disadvantages of the conventional example and effectively illuminate both sides of the vehicle, especially at night when the vehicle is stopped.

[Means for solving problems]

In this invention, the cornering lamps installed at the left and right corners of the car are activated by the turn signal lighting current that flows when the turn signals installed in the car are activated, and the left and right corners of the corresponding cornering lamps are activated. In a cornering lamp lighting device that includes a cornering relay that selects and controls lighting of one of the cornering lamps, a handbrake switch that detects the operating state of the vehicle's handbrake is attached to the cornering relay, and the cornering relay The system is equipped with a cornering lamp simultaneous lighting control function that activates when a signal from the brake switch and a lighting signal for the car's headlights are input, selecting and controlling the lighting of the left and right cornering lamps at the same time. . This aims to achieve the above-mentioned purpose.

[Example of idea]

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

The embodiment shown in FIG.
A cornering relay 6 that is activated by the turn signal lighting current that flows when the turn signals A and 3B are activated, and selects and controls lighting of either the left or right cornering lamp 1A or 1B among the corresponding cornering lamps 1A and 1B. It is equipped with This cornering relay 6 is also provided with a handbrake switch 12 that detects the operating state of the vehicle's handbrake. And cornering relay 6
is configured as shown in Fig. 2, and is activated when a signal from the handbrake switch and a lighting signal for the vehicle's headlights are input, and it simultaneously selects the left and right cornering lamps 1A and 1B mentioned above and controls the lighting. Equipped with a cornering lamp simultaneous lighting control function. Reference numeral 5 indicates a power supply section for the lamp.

To explain this in more detail, cornering lamp 1
A, 1B and blinker lamps 2A, 2B, 3
Each of A and 3B is a cornering lamp relay 6
Depending on the selection operation, all of the lamps are turned on at the same time or one of them is turned on. Of these, cornering lamps 1A and 1B
For example, when the steering wheel is in the neutral position, both of them are illuminated at the same time as necessary, as will be described later.

The cornering lamp relay 6 in this case is activated by the ON operation of the lighting switch circuit 10. The lighting switch circuit 10 is comprised of a handbrake switch 12 and a manual switch 13, as shown in FIG.
When either one of these switches 12, 13 is off (OFF), the lighting switch circuit 10 is set to the off state. Further, numeral 12A indicates a handbrake warning light, numeral 16 indicates a flasher circuit, and numeral 1
7 indicates a headlight relay.

Next, the lighting operation of each lamp will be explained.

First, when the headlight switch 11 is turned on, the headlight relay 17 is activated and the power source 5 is applied to the headlamp 4, thereby lighting the headlamp 4. In this case, as shown in FIG. 1, the output of the power supply section 5 is also applied to the cornering lamp relay 6. On the other hand, headlight switch 1
When the headlight relay 17 is turned off, the headlight relay 17 does not operate, and therefore the headlamp 4 does not light up.

In addition, the flasher 16 and each turn signal lamp 2
When the turn signal relay 16A, which is a changeover switch installed between the flasher lamps A, 2B, 3A, and 3B, is energized by a turn signal switch (not shown) and selects one of the lamps (for example, the turn signal lamps 2A and 2B), the flasher 16 The selected one blinker lamp is controlled to turn on.

In this case, the blinker lamp 2 whose lighting is controlled
As shown in FIG.
It functions as a control signal to turn on the light (R side in the figure). Specifically, transistors Tr ₃ , Tr ₄ and
TrR ₁ is made conductive in sequence, thereby activating the corner lamp relay 6R. Due to the action of this corner lamp relay 6R, cornering lamp 1
The relay switch SWR that conducts to A is set to ON, and the cornering lamp 1A is turned on.

Similarly, when the blinker lamps 3A and 3B are controlled to turn on, a portion of the lighting current is diverted to the cornering lamp 1B as shown in FIG.
(L side in FIG. 2) functions as a control signal for lighting. Specifically, the transistor Tr ₁ ,
Tr ₂ and TrL ₁ are made conductive in sequence, thereby activating the corner lamp relay 6L. Due to the action of the corner lamp relay 6L, a relay switch SWL for energizing the cornering lamp 1B is set to ON, and the cornering lamp 1B is turned on.

Next, a case will be described in which the handbrake 12 is further activated while the output of the power supply unit 5 is applied to the cornering relay 6, that is, the headlamp 4 is turned on. In this case, it is assumed that the manual switch 13 is also turned on.

In this case, the turn signal relay 16A is in the neutral position (see FIG. 1). Therefore, no current for turning on the turn signal lamp is input to the cornering relay 6. On the other hand, when the handbrake switch 12 (and manual switch 13) is turned on under such a condition, the cornering lamp relays 6R and 6 are turned on as shown in FIG.
L are conducted at the same time, cornering lamps 1A,
The on/off switches SWR and SWL for 1B are turned on at the same time, thereby turning on the cornering lamps 1A and 1B at the same time. When the hand brake switch 12 or the manual switch 13 is released, the cornering lamps 1A and 1B are turned off at the same time.

[Effect of idea]

Since the present invention is configured and functions as described above,
According to this, by setting the handbrake switch to the on state, both sides of the vehicle can be illuminated with appropriate brightness at night, making it easier and more efficient to lift and lower cargo in dark places. In addition, if such auxiliary lighting is not required, the cornering lamps can be turned off by opening the handbrake switch or its circuit, and turning on the cornering lamps requires turning on the handbrake switch. from,
It is possible to provide an unprecedented and practical cornering lamp lighting device that can completely prevent the inconvenience of accidentally turning on the lamp while the vehicle is traveling straight ahead.
