Embodiment Construction

[0018] The vehicle high beam automatic switching device is composed of a low-light sensor, a wind speed sensor, a steering wheel angle sensor and a control circuit.

[0019] The low-light sensor is installed at the front windshield of the interior rearview mirror of the car, and is composed of a plastic rectangular housing 2, a light collecting cover 4, a photoresistor 5, a fixing plate 6, a side reflective lens 3, and a transparent dimming lens 1. The light collecting cover 4 is composed of two intersecting light cups, fixed on the rear part of the rectangular housing 2 through the fixing plate 6, and two photoresistors 5 are installed in the center of the light cups, and the photoresistors 5 are connected in the control circuit. A side reflective lens 3 is installed inside the housing 2 both sides, and the transparent dimming lens 1 is installed at the front opening of the rectangular housing 2 .

[0020] The two concentrating cups collect weak light and concentrate it at th...

Abstract

The invention discloses a vehicular high-beam headlight auto-switching device which automatically controls on and off of high-beam headlights by detecting brightness of incoming light, vehicle speed and vehicle turning angle. The vehicular high-beam headlight auto-switching device comprises a low light sensor, a wind speed sensor, a steering wheel angle sensor and a control circuit; the low lightsensor measures intensity of the incoming light; the wind speed sensor measures speed of a vehicle; the steering wheel angle sensor provides two switch nodes; the three measured values are converted into electrical signals input to the control circuit; the control circuit switches to the high-beam headlights if the three values all meet the conditions, and switches to low-beam headlights otherwise. The vehicular high-beam headlight auto-switching device is simple in structure, easy to implement, low in manufacture cost, applicable to any vehicle type and suitable for popularization to common vehicle types, is highly applicable and suitable for use in any environment, provides good intelligence of high-beam headlights and causes less harm due to untimely switching of the high-beam headlights.

Description

technical field [0001] The invention belongs to the technical field of vehicle lights, and in particular relates to technologies and devices for automatically switching lights of various vehicles. Background technique [0002] When the vehicle is driving at night and in dark places, the lighting of the car lights is essential. According to the purpose of the car lights, it can be divided into low beam and high beam. According to traffic rules and driving needs, far and low beams should be switched according to certain rules. When vehicles meet at night, they must switch to low beams, otherwise the high beams will be dazzled and cause accidents. In addition to the impact on oncoming vehicles, the high beam will also appear as a large area of ​​halo in the rearview mirror of the vehicle in front, and the halo will reduce the visibility of the road ahead. If you want to merge or It is also completely impossible to turn and observe the situation behind from the rearview mirro...
