Description

U-turn indicating device of automobile

The present invention relates to a U-turn indicating device for a vehicle capable of informing a driver of a subsequent U-turn, and more specifically, a left stop light and a left turn signal of an U-turn vehicle alternately. By blinking as it goes, the U-turn will be communicated to subsequent vehicles without affecting the existing traffic signal system to prevent collisions, collisions and traffic jams.

Conventionally, when a vehicle is to be rotated or u-turned, the left turn vehicle or the U-turn vehicle turns left or u-turn while the left turn indicator flashes in the same way, so the signal of the vehicle is difficult to distinguish. -It is not easy to determine whether to turn or turn left, so there is a problem that a collision accident (contact accident), a collision accident and traffic congestion factors occur.

In general, left turn and u-turn are mostly performed together in the first lane next to the center line, so vehicles that want to turn left or u-turn are driven in one lane. When driving in one lane, a stop signal comes to the traffic light at the intersection. Once stopped, a left turn or u-turn is made when a left turn signal is received. However, when a left turn signal is received while driving, a left turn vehicle turns on the left turn light and continues to sprint while the left turn signal is the same. After turning on and suddenly decelerating and making a U-turn, contact accidents frequently occur between the preceding vehicle and the subsequent vehicle turning left, and some vehicles are running faster than usual before the left turn signal changes, thereby increasing the possibility of a traffic accident.

That is, when the vehicle receives a left turn signal while driving, the rotating vehicle rotates about 90 ° from the turning point to drive on the left side of the road, and the U-turn vehicle rotates about 180 ° to drive in the opposite direction, so it turns left during the U-turn. The motor decelerates more rapidly than when rotating.

In addition, when there is a vehicle that turns right on the left roadway, the left turn vehicle rotates without being concerned about it, but the U-turn vehicle rotates rapidly after decelerating because it may collide with the right turn vehicle.

Therefore, if the preceding vehicle suddenly decelerates while turning on the left turn indicator while making a U-turn, the subsequent vehicle is embarrassed by the sudden deceleration of the preceding vehicle, so that it does not take proper measures and suddenly collides with the preceding vehicle or avoids it. If you turn right and turn to the next two lanes, you will not be able to avoid collisions with vehicles that run in two lanes. This accident is more likely to occur when a large number of vehicles are continuously running on a heavy road. There is a problem that is caused.

In addition, although a plurality of U-turn indicating circuits have been invented in the past, the configuration is complicated and difficult to install in existing vehicles, and it is difficult to practically use because it does not help the safe driving by affecting the existing traffic signal system. .

Accordingly, the present invention is to make the left stop light and the left turn signal of the U-turn vehicle alternately flashing to inform the subsequent vehicle of the U-turn driving intention without affecting the existing traffic signal system, thereby causing a crash or crash accident. And to prevent traffic congestion.

In addition, when the handle is released after the u-turn is finished, the u-turn indicator is automatically turned off by a one way off switch, and the emergency light must be activated in priority to all signals. When the u-turn indicator of the present invention is turned off (OFF).

C contact C4), the contact C6 of the relay Ry6 for temporarily shutting off the tail light power supply to the tail light terminal of the left stop light SL, and the b contact of the relay Ry4 The contact C5 of the relay Ry5 is connected in series.

Reference numeral (2) is a tangy piece, (4) is an interference piece to prevent excessive bending.

According to the present invention configured as described above, when the driver wants to make a U-turn while driving, the driver is a kind of push button having a locking structure, and when the driver presses the U-turn switch (US) installed near the driver's seat panel or the relay, the relay The battery power supply B + is supplied to the coil of Ry1, and the self-hold contact C1 of the relay Ry1 is turned ON. Therefore, the battery power supply B + becomes the magnetism of the relay Ry1. It is supplied to the U-turn indicator light (UL) installed in or near the driver's seat through the holding contact point (C1), and is turned on.The U-turn indicator light (UL) is turned on by the self-holding contact point (C1) of the relay Ry1. Is continuously lit, the driver of the vehicle can confirm that the U-turn is being instructed.

In addition, since the power supply B + supplied through the self-holding contact C1 of the relay Ry1 is supplied to the coil of the relay Ry2, the flasher to the left direction indicator light LL through the contact C2 of the relay Ry2. The flashing power of the unit FU is supplied, so the left turn indicator LL flashes.

In addition, since the power supply B + supplied through the magnetic holding contact C1 of the relay Ry1 is supplied to the coil of the relay Ry4, the b contact point and the c contact point of the relay Ry4 are connected (ON) to the left stop lamp. Since the braking signal input to the power supply is temporarily cut off during the u-turn period, the left stop light is temporarily turned off, and the flashing power of the flasher unit FU is supplied to the coil of the relay Ry5 and the contact point of the relay Ry5 ( Since C5) is repeatedly turned on / off (ON / 0FF), the power B + supplied through the self-holding contact C1 of the relay Ry1 is converted into a flashing signal and supplied to the left stop light SL. Therefore, the stop light SL blinks.

Since the contact point of the relay Ry5 is configured as the B contact point, the left stop light SL is turned off when the left turn indicator light LL is turned on, and the left stop light SL is turned off when the left turn signal LL turns off. Since the left turn indicator (LL) and the left stop light (SL) flashes alternately, it is possible to communicate a u-turn to a driver of a subsequent vehicle.

In addition, since the power supply B + supplied through the self holding contact point C1 of the relay Ry1 is supplied to the coil of the relay Ry6 and the contact point of the relay Ry6 is turned off, the taillight is turned off even when a tail light signal is input. When lit, the left tail light is temporarily turned off during the u-turn period to avoid confusion with the u-turn signal.

On the other hand, when the right turn indicator RL or the emergency light is operated, the flashing power of the flasher unit FU is supplied to the coil of the relay Ry3, so that the relay Ry3 contact C3 is turned on / off. Is repeated, but the self-hold of the relay Ry1 is released in the period in which the contact point C3 of the relay Ry3 is initially turned off, so that the battery power B + supplied to the relay Ry1 is cut off and U- The turn indicator (UL) goes out, so the U-turn is released and the U-turn indicator (UL) goes out.

In the above state, even when the U-turn switch US is turned ON in the state in which the right turn indicator RL is operated, the contact C3 of the relay Ry3 is repeatedly turned off so that the self-holding circuit is self-holding. Since the circuit) is released continuously, the U-turn display device of the present invention does not operate. Therefore, the emergency light operates in priority to all signals, and the right turn signal operates in a lane.

In the present invention, the one-way off switch (switch OFF in one direction: 0S) mounted to the multifunction switch is rotated to the left by a protrusion piece (d) fixed to the steering wheel as shown in FIG. 4. b) remains ON, but when the steering wheel rotates to the right, the contacting part (a) and (b) as shown in FIG. Since the power (B +) supplied to the coil of the relay (Ry1) is turned off (OFF) and the self-holding contact is turned off, the U-turn indicating device of the present invention is automatically turned off (off) to facilitate operation convenience. .

In the present invention, when the steering wheel is installed on the right side of the vehicle, the right stop light may be connected instead of the left stop light SL, and the right turn light RL may be connected instead of the left turn light LL.

As described above, the present invention flashes the left stop light and the left turn signal of the U-turn vehicle alternately, so that the subsequent vehicle can be informed of the U-turn intention without affecting the existing traffic signal system, thereby causing a collision or crash accident. And traffic congestion factors are eliminated.

In addition, when the U-turn is completed by the one-touch operation, the U-turn indicating device is automatically turned off (OFF), which is convenient for operation, which helps in safe driving.

In addition, if the driver gives up the U-turn, only the direction indicator lever needs to be lifted up slightly, so the one-way off switch is turned off and the self-holding of the relay (Ry1) is released, so it is much more used than pressing a separate u-turn release switch. This is convenient, even if you give up the U-turn and move to the right lane, you can simply drive the right turn signal to facilitate the driving.

In addition, since the U-turn indicator of the present invention is turned off when the emergency light or the right turn indicator RL operates, the emergency light and the turn indicator operate in preference to the u-turn signal, so that traffic safety can be promoted. There is.
