A control method and device for automatically turning off automobile headlights

Abstract

The invention discloses a control device for automatically turning off an automobile headlamp. The control device includes a fixing plate, a first sleeve frame and a second sleeve frame are clamped tothe top of the fixing plate. The second sleeve frame is located on the side edge of the first sleeve frame, a ballast, a photosensitive switch and a power socket are sequentially arranged on the inner side of the first sleeve frame, a temperature controller and a relay are arranged on the inner side of the second sleeve frame, and a plurality of sets of elastic fixing supporting feet are installed at the bottom of the fixing plate. The elastic fixing supporting feet are arranged at the bottom of the fixing plate; the whole fixing device is fixed through the fixing pieces on the elastic fixingsupporting feet; spring rods are arranged on the inner sides of the elastic fixing supporting feet, extrusion resistance can be achieved, the extrusion resistance of the whole control device is improved, electronic devices can be conveniently installed and fixed through the first sleeve frame and the second sleeve frame, and the heat dissipation performance of the whole device is effectively improved by clamping heat dissipation clamping plates into the inner sides of the first sleeve frame and the second sleeve frame.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a control method and device for automatically turning off a headlight of an automobile. Background technique [0002] With the advancement and development of science and technology, the function of automatic switch is gradually realized in the headlights of cars. The headlights of cars use photosensitive sensors to sense the light intensity, and cooperate with the photosensitive switch to control the on and off of the power supply. The photosensitive sensor controls the photosensitive switch to close when the light is strong. , so that the headlights are turned off, and the photosensitive sensor controls the opening of the photosensitive switch when the light is weak, so that the car headlights are turned on, so as to realize the automatic switch of the headlights, eliminating the trouble of manual switches, so that the car headlights can be switched on and off. It is more timely when c...

Problems solved by technology

[0004] The purpose of the present invention is to provide a control method and device for automatically turning off the headlights of a car, which can effectively solve the problem that the existing control device for automatically turning off the headlights of a car has a general anti-extrusion effect after being installed on the frame of the car. When being squeezed for a long time, it is easy to cause the overall damage of the control device; the existing automatic headlight control device is installed scattered among the various electronic devices, which is not convenient enough for maintenance, and it is not convenient enough for disassembly; the existing automatic The overall heat dissipation performance of the control device for turning off the headlights of the car is average, so the service life of the control device for automatically turning off the headlights of the car is generally not long, and it needs to be replaced frequently. By setting elastic fixing feet at the bottom of the fixing plate, through elastic The fixing piece on the fixing foot fixes the whole fixing device, and the spring rod is set on the inner side of the elastic fixing foot, which can resist extrusion and improve the extrusion resistance of the whole control device. By setting the first set frame and the second set frame, it is convenient for each The electronic components are installed, fixed and disassembled, and the heat dissipation card board is snapped into the inside of the first set frame and the second set frame, which effectively improves the heat dissipation performance of the whole device
