Description

[0001] VEHICLE U-TURN WARNING DEVICE

[0002] The invention relates to the automotive industry, in particular to warning means, and can be used to warn of vehicle U-turns at intersections and roads.

[0003] Currently, vehicles are equipped with direction indicators in the headlights, but the left turn signal does not fully ensure safe actions for the driver making a U-turn, since a slightly larger distance is required to complete the U-turn maneuver in order to fit into the intermediate space to complete the maneuver.

[0004] The vehicles following him, due to the space created, simultaneously perform a left turn maneuver, thereby creating an obstacle for the driver of the vehicle making a U-turn, thus creating a traffic jam and an emergency situation at the intersection.

[0005] A device for maneuvering a vehicle to turn around on roads is known, made in the form of a rectangular panel consisting of two plates of transparent organic glass secured with tin strips, on the surface of the outer plate there are holes to form a shape for fixing the bulbs according to the size of the LED strip, the power supply is supplied through a toggle switch and a relay interrupter, while the wires are laid in the cabin inside the trim / KZ 1374 U, published 12 / 15 / 2015 / .

[0006] The disadvantages of this analogue include the impossibility of installing the device inside the rear light of a vehicle and the lack of a factory option for warning of vehicle reversal.

[0007] The closest analogue in technical essence to the claimed invention is a device for maneuvering a vehicle U-turn on the road, made as a separate option in an electronic wireless version, consisting of a U-turn sign made with an LED strip, glued with the help of colorless double-sided tape of the ЗМ brand into the lower left corner of the rear viewing glass of the vehicle; a receiving unit with electronic content, which is attached with simple double-sided tape under the interior trim near the U-turn sign and a 12v power supply; a remote control with electronic content fixed with simple double-sided tape next to the turn lever on the panel of the vehicle / KZ 2990 U, published 23.07.2018 / .

[0008] The disadvantages of this analogue include the impossibility of installing the device inside the rear light of a vehicle and the lack of a factory option for warning of vehicle reversal.

[0009] The objective of the invention is to create a new improved design of a vehicle turn warning device built into the rear headlight of a vehicle.

[0010] The technical result is the reliability and durability of the elements of the vehicle turn warning device inside the rear light, the possibility of installing the warning device by the manufacturer during vehicle assembly.

[0011] This is achieved in that the means for warning a vehicle of a U-turn, including a U-turn sign made of an LED strip, according to the invention, contains an electrical board consisting of at least one assembly of electrical elements - resistors, diodes, transistors, LEDs and a capacitor, connected according to the electrical circuit indicated in Figure 1, wherein the U-turn sign made of an LED strip is installed inside the rear headlight of the vehicle.

[0012] One assembly of electrical components includes two resistors, a diode, a transistor and two yellow LEDs.

[0013] Figure 1 shows a basic electrical circuit diagram of the connection of electrical elements of the vehicle turn signal warning system, on which the following positions are indicated: Q - transistor; D - diode; R - resistor; C - DC capacitor; HL - yellow LEDs.

[0014] To assemble the claimed invention, the following electronic components are required: BC847 transistors (marked with the letter Q on the diagram); 1N4148 (KD522) diodes (marked with the letter D on the diagram); 100 Ohm, 470 Ohm, 1 kOhm resistors (marked with the letter R on the diagram); 35 V, 470 μF DC capacitor (marked with the letter C on the diagram); 2-5 V yellow LEDs (marked with the letter HL on the diagram).

[0015] The number of elements depends on the length of the LED strip. That is, on the length of the U-turn sign. One circuit consists of 20 assemblies (one assembly includes: 1 resistor of 470 Ohm, 1 resistor of 1 kOhm, 1 diode, 1 transistor and 2 LEDs). To extend this circuit, you need to add a 35 volt, 470 μF DC capacitor.

[0016] The invention is carried out as follows.

[0017] Example.

[0018] For the claimed invention to work, it is necessary to add an additional stage of the turn signal switch to the left side of the vehicle. Thus, when the second stage of the turn signal to the left is turned on, the turn signal lights up.

[0019] To implement the above actions, a positive voltage of +12 V from the ignition switch is supplied to the electrical board according to the diagram in figure 1. The voltage is supplied to the positive contact of the LED through a 470 Ohm resistor. Power from the turn signal is supplied to the P contact of the diode through a 100 Ohm resistor, and voltage from the N contact of the diode goes to a 1 kOhm resistor. Then, through this resistor, the voltage goes to the base of the NPN transistor. Negative voltage from the vehicle body is supplied to the emitter of the transistor. Thus, the transistor opens and negative voltage is supplied to the LED from the collector of the transistor. Diodes must be installed in the sequence of each assembly.
