Automatic switching device for high-beam lamps and low-beam lamps of automobile

Abstract

The invention discloses an automatic switching device for high-beam lamps and low-beam lamps of an automobile. The device comprises an illumination intensity detector, a controller, a timer, a headlamp control switch, the low-beam lamps and the high-beam lamps. The illumination intensity detector is installed on the edge of a headlamp on the left side and used for detecting the illumination intensity of lamplight of headlamps of an automobile running oppositely and transmitting illumination intensity information to the controller. The controller receives the real-time illumination intensity information and judges whether a given condition is met or not and if the given condition is met, the headlamp control switch is triggered, so that the high-beam lamps of the automobile are turned off. After the meeting of the two automobiles, an automobile driver can manually turn on the high-beam lamps according to actual requirements. By the adoption of the automatic switching device, the influences on normal automobile running due to the dazzle are avoided, and the automobile running safety in the automobile meeting process at night is greatly improved; the switching device is simple in structure, convenient to operate, economical and reliable; and the party affected by the high-beam lamps has the active control power, the high-beam lamps and the low-beam lamps are switched more accurately in time, and the requirements of the actual condition are met.

Description

technical field [0001] The invention relates to the technical field of automobile auxiliary safety electronic devices, in particular to a device for automatically switching high and low beams of automobiles. Background technique [0002] Driving at night often requires the use of high beams to maintain normal driving due to insufficient ambient illumination, especially when driving on low-grade roads such as suburban roads and country roads without street lights. Although the use of high beams provides safety for driving at night, when two vehicles meet, the work of switching from high beams to low beams needs to be done manually by the driver, and due to various reasons, most drivers cannot follow the requirements. Normal switching of high and low beams will cause discomfort to the vision of oncoming vehicle drivers, non-motor vehicle drivers, pedestrians, etc., and cause glare, so that drivers and pedestrians affected by high beams cannot see the road ahead clearly , Seri...

Although the use of high beams provides safety for driving at night, when two vehicles meet, the work of switching from high beams to low beams needs to be done manually by the driver, and due to various reasons, most drivers cannot follow the requirements. Normal switching of high and low beams will cause discomfort to the vision of oncoming vehicle drivers, non-motor vehicle drivers, pedestrians, etc., and cause glare, so that drivers and pedestrians affected by high beams cannot see the road ahead clearly , seriously affecting normal driving safety

In this regard, relevant personnel have done some discussions, but most of them are passive to deal with the glare caused by the high beam lights of oncoming vehicles, such as anti-glare glasses, front windshield photosensitive glass, and lifting devices for translucent baffles. Although this type of device can reduce the impact of glare on the driver to a certain extent, it also brings some inconvenience to the driver and affects normal driving. For example, wearing anti-glare glasses for a long time will make the driver feel uncomfortable; Although the use of photosensitive glass and translucent baffles can reduce the light intensity of the other vehicle's lights, it will also affect the driver's recognition of other objects. Therefore, it is necessary to change the traditional way of thinking and design a car that can actively deal with the glare of the car lights. device
