Description

The utility model relates to the field of ensuring the functioning of lighting devices using halogen lamps powered by a direct current source and can be used to control halogen high beam lamps in the daytime running light of any vehicle.

The well-known control module of car lighting equipment (Patent for the invention of the Russian Federation No. 2339523, IPC B60Q 1/00, H01H 3/02, publ. 11/27/2008). The module includes a housing of dielectric material with latches for mounting on the dashboard and front panel. The case contains the first printed circuit board on which there is a five-position rotary switch for outdoor lighting, a second and third printed circuit board, a frame for the wheels of the dimmer for controls and instruments and a headlight leveling switch, a rack for attaching the second and third printed circuit boards, a pin block for connection to power circuits and external devices and fixed rotary switch contacts. The switch has the initial “off” position, as well as the positions corresponding to the side-beam and dipped-beam modes, the “parking” mode with the navigation lights on when the dashboard is unlit and the number plate and the “AUTO” mode with the low-beam on when driving in the daytime time. On the first printed circuit board, in addition, there are mounted elements of the lighting regulator for controls and devices, electronic components of the front fog lamp control unit and the rear fog lamp control unit, and the aforementioned pin block is also located. On the second printed circuit board, a variable resistor and an illumination element of the lighting regulator of controls and devices are mounted, and on the third printed circuit board, resistors of the module electric circuit and a backlight element of the headlight beam corrector are mounted. The second and third printed circuit boards together with the rack form a structural unit in the form of a console, on the different sides of which are placed the wheels of the dimmer for controls and devices and the headlight leveling switch. This technical solution is intended for switching automobile electrical control circuits for head lighting, front fog lights, rear fog lights, license plate light, tilt angle of the light beam of car headlights and to control the level of illumination of controls and devices. Its disadvantage is the complexity of the electronic circuit and the inability to use the device to control the brightness of halogen lamps powered by direct current.

A device for controlling the brightness of halogen incandescent lamps (Patent of Ukraine No. 45433, IPC H05B 39/00, G05F 1/66, publ. 10.11.2009, Bull. No. 21, 2009), which contains the first resistor connected via a switch lighting with a positive pole of the power source and the first output of a halogen lamp, the second output of which is connected to the negative pole of the power source, the second resistor connected to the light switch and one of the terminals of the relay winding, the second output of which is connected to the negative pole of the power source, and normal open relay contact connected to the positive pole of the power source and the first terminal of the halogen lamp, wherein the first resistor is configured with a negative temperature coefficient of resistance, and the parallel winding of the relay switched capacitor forming a second resistor integrator whose time constant determines the duration of heating and off the halogen lamp. This device has a limited scope of use, that is, it is used only to switch on / off the high and low beam headlights when driving oncoming traffic. Moreover, such actions are carried out not automatically, but by the driver.

From the prior art, the closest device of the same purpose as the claimed device was not found.

The utility model is based on the task of creating a high-beam lamp control device in daytime running lamp mode, which makes it possible to control the high-beam lamps automatically, providing fuel and resource saving for vehicle lighting devices.

The problem is solved by creating a driving lamp control unit in the daytime running lamp mode, comprising a housing and a printed circuit board with a terminal block in which, according to a utility model, the printed circuit board contains a blocking input monitoring unit connected to the terminal block and a width generating unit -pulse signal connected to the terminal block and the adjustment unit connected to it, designed to change the duty cycle of the pulses of the generated signal, and all blocks are connected us with the common bus of the vehicle, which is connected to a separate terminal of the terminal block.

In addition, voltage is supplied to the pulse-width-signal generation block and to the adjustment block through a relay controlled by the blocking input control block, said relay being installed outside the housing.

The proposed device for driving high beams in daytime running lights has its own name "AVIOR-91".

The proposed device is designed to control the brightness of the high-beam lamps in daytime running lights without driver intervention (automatically), which, in contrast to the use of low beam or fog lamps in daytime running lights, provides significant advantages in saving fuel and the resource of lighting devices of the vehicle (high beam) thanks to its following functions:

a) the supply of low voltage to the high-beam lamps (significantly lower than the on-board battery supply +12 V), which, firstly, can significantly reduce their power consumption and reduce energy consumption, and secondly, increase their service life by ensuring operation not at full capacity;

b) the absence of the need to turn on the side lighting, backlight plate, illumination of the instrument panel and center console;

c) the smooth inclusion of high-beam lamps with a gradual heating of the filament.

Also, the use of this device is fully consistent with international requirements for daytime running lights of vehicles, namely: "... the fire directed forward and used to provide better visibility of the vehicle when driving in the daytime", "... daytime running lights must be on automatically when the engine start / stop control is set to the “on” position. It must be possible to activate and deactivate the automatic activation of daytime running lights without the aid of a tool. Daytime running lights shall be switched off automatically when the headlights are switched on, except when the headlights are turned on for a short period of time to signal traffic participants ... ” That is, this device provides improved traffic safety on roads, prevents the risk of accidents between road users during their movement during daylight hours.

When installing this device, another very important requirement for all vehicles without exception is not violated - the prohibition of making changes to the design of the vehicle (for example, the installation of additional headlights, light devices, etc. is prohibited if such equipment is not approved (provided) manufacturer). At the same time, the ban on making changes to the wiring of the car is not reflected anywhere. That is, when installing this device, the design does not change, all standard wiring and external lighting devices remain unchanged.

The essence of the technical solution of the proposed utility model is illustrated by the structural-functional diagram presented in FIG.

The high-beam lamp control device in daytime running lamp mode comprises a housing (not shown) and a printed circuit board 1 with a terminal block 2, which has eight contacts 3, 4, 5, 6, 7, 8, 9, 10. Printed the board 1 contains a blocking input control unit 11, which is connected to the terminal block 2, a pulse-width signal generation unit 12, which is connected to the terminal block 2 and the adjustment unit 13 connected to it, is designed to change the duty cycle of the pulses of the generated signal, all of which are mentioned conn inen with the common bus of the vehicle, which is connected to terminal 3 of terminal block 2. The voltage to the pulse-width-signal generation unit 12 and to the adjustment unit 13 is supplied through a relay 14, which is controlled by the control unit for the blocking inputs 11, and this relay 14 is located outside the housing .

The body of the device is made airtight, for example, from plastic.

The device operates as follows.

When the vehicle engine is started, when the ignition key 20 is switched to the “ignition” (“ON”) position, the device is powered by an electric circuit through terminal 8 of terminal block 2, and the blocking inputs control unit 11 closes (via pin 7) relay contacts 14 and the voltage from the vehicle’s power source is supplied to the pulse-width-pulse signal generation unit 12 and to the adjustment unit 13, which causes the device to turn on. To enable the device to work on pin 6, a command must be issued to enable the daytime running lights in the form of a lack of minus (mass), which occurs only when the engine is running (power supply of the warning lamp "Oil pressure" 17). The use of this command in the device’s operation algorithm can significantly reduce the load on the battery 18 when starting the engine, which is especially necessary in the winter.

The main blocking commands are sent to the terminals 4, 5 and / or 6 through the wires to the control unit for the blocking inputs 11 of the circuit board 1 of the device in the form of a voltage of +12 V (or 0 V). As the main working (blocking) command, the voltage of the dipped-beam switching circuit 15 (to terminal 4) is used. Thus, when the vehicle’s engine is running, the dipped-beam headlights 15 are off and the “Hand brake” 16 is lowered, daytime running lights are automatically turned on (the device feeds the high-beam headlamps 19 with its voltage), and when the dipped-beam headlights 15 are turned on or the “Manual brake” is applied »16 the operation of daytime running lights is prohibited, that is, the device automatically turns off.

The device operation indication in the daytime running light mode is initiated by the illumination of the standard high beam warning lamp on the dashboard of the vehicle, while the level of the control lamp in the daytime running mode is much lower than the level of the control lamp in normal mode (high beam).

The high-beam lamp control device in the daytime running mode “AVIOR-91” is installed on any vehicles in order to expand the capabilities of the vehicle's high-beam headlights to give them the additional function of daytime running lights in energy-saving and resource-saving modes.
