Detailed ways

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail as follows:

As shown in accompanying drawings 1 and 2, the light-controlled headlight dimmer of an automobile is characterized in that it is composed of a light sensor G, a dimmer control module B, a relay J, and a fuse F connected sequentially through the main circuit A of the dimmer , the dimmer main circuit A is connected to the vehicle power supply E, the light sensor G is internally provided with a device capable of sensing light intensity, the dimmer control module B is internally provided with a signal transmitting device and a receiving device, and the dimmer main circuit On and off control device, the inside of the relay is provided with an electromagnet D connected to the main circuit A of the dimmer, and two electromagnetic switches respectively controlling the high beam and the low beam of the vehicle (that is, K1 and K3 in the figure The high beam electromagnetic switch composed of K2 and K4 constitutes the low beam electromagnetic switch, wherein K1 and K3, K2 and K4 respectively represent different on or off connection points), one end of the electromagnetic switch D is connected to the vehicle power supply E, and the other end The high beam L1 and the low beam L2 of the vehicle are respectively connected, the electromagnetic switch of the high beam is also connected with the low beam through the auxiliary circuit A3, and the electromagnet D is located between the two electromagnetic switches to control the opening and closing of the two electromagnetic switches , The fuse uses a 20 amp fuse. The high beam and high beam electromagnetic switches are connected to the vehicle power supply through the high beam circuit A1, and the low beam and low beam electromagnetic switches are connected to the vehicle power supply through the low beam circuit A2.

During installation, the dimmer is installed on the left front windshield of the vehicle and its circuit is connected with the vehicle power supply.

When driving in the daytime or at night but not in a non-working state, such as when there is no oncoming vehicle, the main circuit of the dimmer is in the disconnected state without power, at this time, the electromagnet in the relay does not work, and the electromagnetic switch of the high beam headlight is in K1 on state. state, the high beam is normally directly connected to the vehicle power supply through the high beam circuit, the low beam electromagnetic switch is in the K2 on state, the low beam is directly connected to the vehicle power supply through the low beam circuit, and the driver of the vehicle can control the high beam lights and dipped beams for normal operation. The circuit connection at this time is shown in Figure 1.

When cars A and B meet each other at night, the light sensor of the light dimmer installed on car A is irradiated by the lights of car B, and the light sensor senses the intensity of the light of car B and transmits the light intensity signal to Dimming control module, when the light intensity reaches a certain pre-set dazzling intensity, the dimmer control module on car A sends out a remote control signal, and the dimmer control module on car B receives the signal from car A. After the signal is received, the control device in the dimming control module that controls the opening and closing of the main circuit of the dimmer immediately connects the main circuit of the dimmer, and the main circuit of the dimmer is energized. After the electromagnet in the relay is energized, an electromagnetic field is generated, and the electromagnetic field will be The electromagnetic switches controlling the high beam and low beam are respectively adsorbed to the positions of K3 and K4, K1 and K2 are disconnected, the high beam is turned off, at the same moment, K3 is turned on, and the vehicle power supply forms a closed loop with the low beam through the auxiliary circuit. The low beams come on. At the same time, the dimming control module of the first car itself will also receive the signal from its own dimming device to automatically turn the high beam into the low beam. The circuit connection at this time is as shown in Figure 2. When the high beam lights become low beam lights, the lights of the other side will not dazzle the driver when the two vehicles are meeting each other, so that the driver can see the road ahead clearly, effectively avoiding traffic accidents due to illegal use of high beam lights when driving at night. resulting in traffic accidents. When the two cars meet and no longer shine on each other, the light sensor of both sides perceives the light intensity to decrease, and the dimming control module disconnects the main circuit of the dimming device, the electromagnet loses power, no longer generates an electromagnetic field, and each electromagnetic switch Return to the original state shown in Figure 1 under elastic action.

When the utility model is actually used, because the light changer can accept the signal sent by the other party as well as the signal sent by itself, so one party equipped with the light changer can automatically switch from the high beam mode when being irradiated by the strong light of the other party In the low beam mode, as long as the vehicle equipped with this dimmer can automatically change from the high beam mode to the low beam mode under strong light, the light change starts from oneself. In addition, under normal circumstances, the low beam cannot shine on the other party's front windshield, so it will not cause glare, but only the high beam can shine on the other party's eyes and cause dazzling.
