Description

The utility model relates to the electrical equipment of vehicles, mainly vehicles, and can be used to temporarily automatically turn on and off the side lights of a car when changing external background illumination without the participation of the driver.

A known electronic device for automatically turning on the vehicle side lights, comprising a sensing element for background illumination, a delay element, a threshold device, a key device, an actuating element connected in series [1].

The closest in technical essence is an electronic device for automatically turning on / off the side lights of a vehicle when it is illuminated by the headlights of a passing vehicle, containing a sensitive element to background illumination, a delay element, a threshold device, a key device, an actuating element connected in series, while feedback circuit, the threshold device is adjustable with a controlled input of the threshold level, and one of the outputs the th element is made by the control, which is connected by a feedback circuit to the controlled input of the threshold device, and the threshold device is configured to abruptly decrease the threshold level with an increase in background illumination above a given level and with the possibility of an abrupt increase in the threshold level with a decrease in background illumination below a predetermined level [2] .

The disadvantage of such devices are low performance. This is due to the use of photoresistors as a sensitive element, which eventually change their resistance and render the device inoperative, as a result of which periodically there is a need for testing and tuning.

The objective of the utility model is to reduce the accident rate on the roads due to poor visibility in the dark.

The technical result of the utility model is to increase the security of a parked vehicle and the safety of passing vehicles.

The technical result is achieved by the fact that the device for automatically turning the vehicle side lights on and off at night when it is illuminated by the headlights of a passing vehicle includes an external light sensor and an ambient light sensor in the cabin in the form of photocells installed in such a way that the outputs the ambient light sensor 2 in the cabin is connected to the enable unit for the inclusion of the sidelights 4 and the first input of the prohibition unit 3, the second input of which is connected with the ignition key, and the output is connected to the first input of the dimensions enable unit 6, while the output of the ambient lighting sensor 5 is connected to the second input of the dimensions enable unit 6, the output of which is connected to the power enable unit 7.

In this case, the ambient light sensors contain two or more photocells.

In FIG. 1 shows a functional diagram of the inventive device, FIG. 2 shows a circuit diagram of this device.

The device for automatically turning on and off the side lights of a vehicle at night in the event of its illumination by the headlights of a passing vehicle includes an ambient light sensor in the passenger compartment 2 connected to an enable switch

the sidelights (headlights for turning) 4 and the prohibition block 3, connected to the ignition key 1 and the power switch 6, connected to the ambient light sensor 5 and the power switch 7.

The device allows you to automatically turn on the vehicle’s side lights (without the driver’s participation) when it illuminates the headlights of a passing vehicle, thereby indicating the dimensions and location of a standing vehicle, and automatically turn off the side lights 4-6 seconds after the lighting ceases, providing additional energy savings for the battery car due to periodic operation of the circuit. The device does not discharge the car’s battery, even if the driver appears only after 3 days.

The device provides for the inclusion of marker lights in conjunction with emergency lights.

The operation of the device is based on recording the average background illumination of the vehicle, converting this level into an electrical signal and issuing a command depending on the set threshold level for turning on and off the side lights. It turns on only in the dark and in an unlit place. The device contains a light sensor 2, made in the form of a main photocell installed in the cabin, the purpose of which is to give permission to the automation in the evening and night. The ambient light sensors 5 are also presented in the form of two or more photocells mounted under the glass of reflectors mounted in the rear view mirror housing. When illuminated by the light of a passing car, they give an electrical signal to the power-on block of dimensions 6, and the machine turns on the side lights (power-on block of dimensions 7). After the illumination of the ambient light sensors 5 (the car drove past), the device turns off the side lights in about 4-6 seconds, thereby preventing the battery from discharging. If the car is parked under a streetlight, then external light enters the light sensor in the passenger compartment 2, which through the prohibition block 3 will prohibit the inclusion of marker lights, as the car is already so clearly visible. The device also includes a unit for switching on additional sidelights (headlights for turning) 4, which is located in front of the bumper at an angle of 40 degrees with respect to the main axis of the car. The installation of these sidelights allows you to highlight the exit onto the side road at night, due to the fact that only the headlights exit the congress is poorly visible. When the turn signal is turned on, the sidelight will also turn on, providing better visibility when exiting the main road. In daylight, the sidelights do not turn on. Block prohibition 3 will not allow the machine to work, because The interior light sensor 2 will be lit by sunlight.

The inventive device operates in the temperature range from -30 to + 50 ° C. The margin of safety of parts allows the device to work in a wider temperature range.

This device increases the security of the parked car and reduces the accident rate on the roads, showing passing vehicles their location. The device can be recommended for use in road service vehicles (rollers, special equipment), as well as truckers who often spend the night on the highway.
