Device for detecting illumination intensity of automobile headlamp

Abstract

The invention discloses a device for detecting the illumination intensity of an automobile headlamp. The device comprises a base. A driving cavity is formed in the inner bottom end of the base. Transmission cavities are formed in the left side and the right side of the driving cavity. A detection mechanism is arranged at the top end of the transmission cavity. A feeding mechanism is arranged between the detection mechanisms. Screw rods are arranged on the left and right end walls in the transmission cavity. The tooth form on the screw rod is transversely arranged. A detection groove is formedin the rear end surface of the transmission cavity. A rack mounting block is slidably mounted in the detection groove, a rack is fixedly mounted on the front end surface of the rack mounting block, the rack is engaged with the screw rod, a detection strip is mounted on the upper end surface of the rack mounting block, and a disc is fixedly mounted at one end, far away from the end wall of the transmission cavity, of the screw rod. The device is simple in mechanism and easy and convenient to use, the procedure of headlamp feeding detection is achieved through cooperation of the threaded screw,light intensity detection of the headlamp is achieved through resistance difference shown by different light intensities of the photoresistor, and meanwhile different control over the headlamp measured at the same time is achieved through the clutch mechanism.

Description

technical field [0001] The invention relates to the technical field of automobile lighting, in particular to a device for detecting the illumination intensity of automobile headlights. Background technique [0002] In today's life, the car has become an indispensable means of transportation for people to travel. The appearance of the car brings people less convenience in life. Whether it is going to work during the day or leaving get off work at night, it shortens the distance between home and work. However, some car owners nowadays replace their car headlights with extremely dazzling lights in order to highlight their individuality. At the same time, there have been scientific studies showing that when the headlight intensity of a certain car is greater than the threshold in the dark, cars driving in the opposite direction cannot see clearly whether it is behind them or not.

[0002] In today's life, the car has become an indispensable means of transportation for people to travel. The appearance of the car brings people less convenience in life. Whether it is going to work during the day or leaving get off work at night, it shortens the distance between home and work. However, some car owners nowadays replace their car headlights with extremely dazzling lights in order to highlight their individuality. At the same time, there have been scientific studies showing that when the headlight intensity of a certain car is greater than the threshold in the dark, cars driving in the opposite direction cannot see clearly whether it is behind them or not. There are obstacles, which cause a lot of hidden dangers to road traffic safety and even endanger personal safety. It is also urgent to detect the light intensity of automobile headlights. A device for detecting the light intensity of automobile headlights set forth in the present invention can solve this problem. question
