Description

[0001] This invention relates to the automotive industry, and more particularly to a warning device that can be used to warn vehicles of making U-turns at intersections and on roads.

[0002] Currently, all vehicles are equipped with turn signals in their headlights, but the left turn signal cannot completely guarantee the safety of the driver when making a U-turn, because it requires a slightly larger distance to enter the middle space to complete the U-turn operation.

[0003] Because of the space created, vehicles behind simultaneously attempted to turn left, obstructing drivers of vehicles making U-turns, causing traffic congestion and creating an emergency at the intersection.

[0004] A vehicle control device for steering on a road is known, which is a rectangular panel consisting of two transparent acrylic panels secured with a metal strip. The outer glass panel has holes of the same size as LED light strips, forming a shape for securing the bulbs. Power is supplied via a toggle switch and a relay circuit breaker, with the wiring routed within a trim strip in the driver's cab (KZ 1374U, published December 15, 2015).

[0005] The drawbacks of this simulator include the inability to install it inside the vehicle's taillights and the lack of a factory-supplied vehicle reversing warning option.

[0006] The closest analogue to this invention in technical substance is a device for manipulating a vehicle to make a U-turn on a road, which is made as a standalone option in an electronic wireless version and includes: a U-turn sign made of an LED light strip, affixed to the lower left corner of the vehicle's rearview window with 3M brand colorless double-sided tape; a receiver unit with electronic components, which is fixed to the underside of the interior panel near the turn sign with ordinary double-sided tape and powered by a 12V power supply; and a remote control with electronic components, fixed to the turn stalk on the vehicle dashboard with ordinary double-sided tape (KZ 2990U, published on July 23, 2018).

[0007] The drawbacks of this simulator include the inability to install it inside the vehicle's taillights and the lack of a factory-supplied vehicle reversing warning option.

[0008] The purpose of this invention is to create a novel and improved design for a vehicle turn warning device that is installed in the rear headlight of a vehicle.

[0009] The technological achievement is the reliability and durability of the internal components of the vehicle turn signal taillight, and the possibility for manufacturers to install the warning device during vehicle assembly.

[0010] According to the present invention, a vehicle turn signal device (including a turn sign made of an LED light bar) comprises a circuit board consisting of at least one electrical component assembly, including resistors, diodes, transistors, LEDs and capacitors, and connected as shown in the circuit of FIG1, wherein the turn sign made of an LED light bar is mounted in the rear headlight of the vehicle.

[0011] An electronic component includes two resistors, one diode, one transistor, and two yellow LEDs.

[0012] Figure 1 shows a basic circuit diagram of the electrical component connections for a vehicle turn signal warning system. The following locations are marked in the diagram: Q - Transistor; D - Diode; R - Resistor; C - DC Capacitor; HL - Yellow LED.

[0013] To assemble this invention, the following electronic components are required: Transistor BC847 (marked with the letter Q in the diagram); Diode 1N4148 (KD522) (represented by the letter D in the diagram); Resistors with 100 ohms, 470 ohms, and 1 kiloohms (marked with the letter R in the diagram); A 35V, 470μF DC capacitor (marked as C in the diagram); Yellow LED 2-5V (marked with the letters HL in the picture).

[0014] The number of components depends on the length of the LED strip, or in other words, the length of the turn sign. One circuit contains 20 components (each component includes: one 470-ohm resistor, one 1000-ohm resistor, one diode, one transistor, and two LEDs). To expand this circuit, a 35-volt, 470-microfarad DC capacitor needs to be added.

[0015] The implementation method of this invention is as follows. Example

[0016] To make this invention effective, an additional turn signal switch stage needs to be added to the left side of the vehicle. This way, when the second stage of the left turn signal is activated, the U-turn light will also illuminate.

[0017] To achieve the above steps, according to the circuit diagram shown in Figure 1, a positive voltage of +12V is supplied to the circuit board from the ignition switch. This voltage is applied to the positive terminal of the LED through a 470-ohm resistor. Power from the turn signal is applied to the P-terminal of the diode through a 100-ohm resistor. The N-terminal voltage of the diode is applied to a 1kΩ resistor. The voltage then reaches the base of the NPN transistor through this resistor. A negative voltage from the vehicle body is applied to the emitter of the transistor. This turns the transistor on, and the collector of the transistor supplies a negative voltage to the LED. A diode must be installed in the circuit of each component.
