Connected to.

Returning to FIG. 1, the description will be continued. The controller 12 has a lifting control circuit 12a, and has connectors CN1 and C
The N3 is connected to the power supply line L ₁ ~L _5, the connector CN2 is connected to the corner pole body 13, its configuration is the same as the conventional.

The connection of the connector CN1 is the same as the conventional connection, the port P ₅ is connected to the battery line L ₃ , the port P ₆ is connected to the ignition line L ₂ , and the port P is connected.
₇ is connected to the back line L ₁ and the port P ₈ is grounded.

Ports P _{1 to} P ₅ of the connector CN1 are a battery terminal, an ignition terminal, and a battery terminal of the lift control circuit 12a.
Connected to the back terminal and ground terminal, respectively. Elevation control circuit 12a according to the voltage level of the line L ₁ ~L ₃ Figure
The motor drive signals M + and M- are generated as described above.

The motor drive signal M + is supplied to the port P _{3 of the} connector CN2, and the motor drive signal M- is supplied to the connector C.
It is supplied to the port P4 of N2.

The port P _{4 of the} connector CN3 connects the back line L ₁ and the port P _{1 of the} connector CN2, and the port P _{10 of the} connector CN3 is the lamp lighting line L.
₄ and the port P _{2 of the} connector CN2 are connected.

Next, the operation will be described. When the back gear is put in the state where the surroundings are bright and the clearance lamp and the license lamp are not lit, the motor 13b is driven by the motor drive signals M + and M- from the lift control circuit 12a, and the pole portion 13a is extended. This improves the visibility of the rear end of the automobile. At this time, the clearance lamp,
Since the license lamp is not lit, the lamp lighting line L ₄ is at low level and the back line L ₁ is at high level. Therefore, the port P _{1 of the} connector CN2 is at a high level, the port P ₂ is at a low level, the diode D2 forming the illumination control circuit 13c is turned on, and the current supplied from the back line L ₁ is the resistance R1,
Flows to the lamp lighting line L ₄ via the diode D2,
Therefore, no current is supplied to the light emitting diode LP1, and the light emitting diode LP1 does not emit light.

Further, when the back gear is put in the state where the surroundings are dark and the clearance lamp and the license lamp are lit, the motor 13 is driven by the lifting control circuit 12a.
b is driven, and the pole portion 13a extends.

At this time, the back line L ₁ is at a high level, and the lamp lighting line L ₄ is at a high level because the clearance lamp and the license lamp are lit.

Therefore, the port P _{1 of the} connector CN2,
Both P ₂ are at high level, and the diode D2 is off. At this time, the motor drive signal M + for driving the motor 13b, the port P ₃ which M- is supplied, P ₄ port P ₃ is a high level for extending pole portion 13a is rotated forward the motor 13b, the port P ₄ becomes low level. Therefore, the cathode side of the diode D1 becomes low level, the anode side of the light emitting diode LP1 becomes high level because the diode D2 is turned off, and a current flows through the light emitting diode LP1, so that the light emitting diode LP1 emits light. Therefore, the visibility can be obtained even when the tip of the pole portion 13a is lit and it is dark.

When the back gear is released, the back line L ₁ becomes low level and the light emitting diode LP 1
Since no current is supplied to, the light emission is stopped. At this time, the drive signals M + and M- of the lift control circuit 12a are inverted and the signal M- becomes high level.
1 and the diode D1 are connected in opposite directions, and no current flows through the light emitting diode LP1. If the light emitting diode LP1 is used as the illumination, the diode D1 is not necessary, but by using the diode D1, the light emitting diode LP1 can be protected and an ordinary light bulb or the like can be used, so that versatility can be improved.

Next, considering the lighting conditions, it can be raised that the back gear is engaged (BACK = Hi), the M- terminal is in a low level output state, and the ILL + terminal is at a high level.

Therefore, in order to turn on the illumination of the corner pole, the vehicle clearance lamp,
The illumination such as the license lamp must be on and the back gear must be on.
The illumination of the corner pole is turned on only when the vehicle is moved backward in a state where vehicle illumination is required, that is, in a dark environment.

Therefore, the pole does not light up while the illumination is not required to light up and the pole is not lit up, so that the illumination life can be extended and light leakage can be prevented when the pole is housed.

FIG. 3 shows a block diagram of the second embodiment of the present invention. In the figure, those parts which are the same as those corresponding parts in FIG. 1 are designated by the same reference numerals, and a description thereof will be omitted.

In this embodiment, the number of connecting wires is reduced by turning on the light emitting diode LP1 arranged at the tip of the corner pole portion 13a when the vehicle is backed.

The controller 21 is composed of an elevating control circuit 12a and connectors CN1 and CN2 which have the same construction as the conventional one. Connector CN11 has a port _{P 11, P 12, P 13} , connects the controller 21 and the power supply line L _1, L _3. The port P ₁₁ connects the battery line L ₃ to the battery terminal and the ignition terminal of the lift control circuit 12a, and the port P ₁₂ connects the back line L ₁ and the lift control circuit 1 to each other.
2a is connected to the back terminal, and the port P ₁₃ is grounded.

The connector CN12 has ports P ₁₄ and P
₁₅ and P ₁₆ are provided to connect the controller 21 and the corner port body 22. The port P ₁₄ of the connector CN12 connects the port P _{12 of the} connector CN11 to the illumination control circuit 22a, and the port P ₁₅ of the lifting control circuit 12a.
Drive signal M + of the motor 13b is connected to the drive signal M + of the motor 13b, and the port P ₁₆ is connected to the drive signal M- of the lifting control circuit 12a and the motor 1
Connect to one end of 3b.

The corner pole body 22 is different from the corner pole body 13 in the structure of the illumination control circuit 12b. The illumination control circuit 22b of this embodiment comprises a diode D ₁₁ and a resistor R ₁₁ .

The anode of the diode D ₁₁ is connected to the port P ₁₄ , and the cathode is connected to the anode of the light emitting diode LP1. One end of the resistor R ₁₁ has a light emitting diode LP1.
1 is connected to the cathode and the other end is connected to the port P ₁₆ .

Next, the operation of this embodiment will be described. Power is turned on that is, if the line L ₃ was placed back gear in the high level state, the port P ₁₁ of the connector CN11,
Both P ₁₂ become high level.

When both the connectors P ₁₁ and P ₁₂ are at high level, the lifting control device 12a causes the battery terminal, the ignition terminal, and the back terminal to be at high level, so that the output signal M + is at high level and M- is at low level for a predetermined time. Set the level, rotate the motor 13b forward, and rotate the corner pole 13a.
Is extended. At this time, port P of connector CN11
_{Since 12} is connected to the port P ₁₄ of the connector CN12, the port P ₁₄ also becomes high level. When the port P ₁₄ is at the high level, the port P ₁₆ is at the low level, so that the die auto D ₁₁ and the light emitting diode LP1 are both connected in the forward direction, so that a current flows through the light emitting diode LP1 and the light emitting diode LP1 is turned on. It emits light and improves the visibility of the corner pole.

When the back gear is released, the lift control circuit 12a outputs the output signal M + for a predetermined time after the elapse of a certain time.
To a low level and the output signal M- to a high level to reverse the motor 13b and shorten the corner pole. At this time, the port P ₁₄ becomes a low level since the reverse gear is released, the port P ₁₆ is for a high level since reversing the motor 13b, connected between the port P ₁₄ and port P ₁₆ A voltage is applied to the diode P ₁₁ and the light emitting diode LP1 in opposite directions,
The light emitting diode LP1 is turned off.

As described above, the illumination of the pole can be controlled by turning on / off the back gear, not in synchronization with the illumination state of the vehicle.

As described above, according to this embodiment, it is possible to reduce the number of wires penetrating around the controller and from the passenger compartment to the rear bumper, so that the cost of connectors and wires can be reduced.

Further, since the number of fitting parts of the connector is reduced, the workability is improved and the number of mounting steps is reduced, so that the cost can be reduced.

Further, the lighting time of the back gear interlocking is much shorter than that of the general pole illumination interlocking with the vehicle illumination, so that the life of the illumination light emitter can be extended.

Further, since the back gear is naturally turned off when the pole is stored, the illumination of the pole interlocking with the back gear is turned off, so that light leakage during storage can be prevented.

[0064]

As described above, according to claim 1 of the present invention, since the illumination of the illumination can be controlled in accordance with the state control signal for instructing the state of the corner pole, the state in which the corner pole is stored. It does not cause the illumination to be turned on, and the illumination can be turned on only when necessary, the illumination can have a long life, and the merchandise can be improved.

According to the second aspect of the present invention, since the lighting of the illumination can be controlled according to not only the state control signal but also the lighting control signal for controlling the lighting of the illumination, the lighting of the illumination is instructed and the corner pole is extended. Illumination can be turned on in a lit state, illumination can be turned on only when it is really needed, and the life can be further extended and the marketability can be further improved.
