The electromagnet 14 includes an iron core and a magnetic induction coil, and the magnetic induction coil is wound outside the iron core.
The photovoltaic solar panel is provided with the bidirectional mirror 3, so that external light is bright in daytime, part of the external light penetrates through the bidirectional mirror 3 and irradiates the photovoltaic panel 4 to generate electricity, and a storage battery (not shown in the figure) is arranged on the back surface of the photovoltaic panel 4 to store the electricity generated by the photovoltaic panel 4 and supply electricity to the electromagnet 14 and other parts when needed;
in daytime, the inside of the shell 1 has obvious light, so that the resistance value of the photoresistor 5 is small, the conductive blocks 16 in the wall grooves 15 are not in contact with the two electric connecting posts 17, only the telescopic springs 13 are in an electrified state, the current in the circuit is large, the equidirectional magnetic field generated by each circle of metal of the telescopic springs 13 is large, and the telescopic springs 13 contract; on the contrary, at night, ambient light is weak, light rays emitted to the photoresistor 5 are weak, at the moment, the resistance value of the photoresistor 5 is large, the current flowing through the telescopic spring 13 is small, and therefore the equidirectional magnetic field generated by each circle of metal is small, the telescopic spring 13 can extend under the elastic action of the telescopic spring and push the outer ring 6 to slide in the shell 1, the permanent magnets 12 move synchronously with the outer ring 6 to drive the conductive blocks 16 to slide in the wall grooves 15 until the conductive blocks 16 move to be in contact with the two electric connecting posts 17, the corresponding electromagnets 14 are electrified to generate a magnetic field and generate magnetic repulsion to the permanent magnets 12, so that the outer ring 6 is pushed to continuously slide in the shell 1 until the permanent magnets 12 move to the electromagnets 14 closest to the protective film 2; the inner 8 and outer 9 polarizers are now covered on the outside of the two-way mirror 3. When external light irradiates the device, the external light firstly passes through the two polarizing films to be reflected by the two-way mirror 3, and finally passes through the polarizing films to finish the whole reflection process, and under the state, the vibration detection directions of the two polarizing films are the same, namely, more incident light can pass through the polarizing films and irradiate on the two-way mirror 3.
Day and night change in real life is a slow change process, namely the resistance value of the photosensitive resistor 5 in the process cannot change suddenly, namely the voltage at two ends of the photosensitive resistor cannot change suddenly, and the current on the rotating spring 11 connected with the photosensitive resistor in series is extremely small.
When the automobile runs nearby and the high beam lamp is not turned off, the high beam lamp irradiates the two-way mirror 3, part of light rays directly pass through the two-way mirror 3 and irradiate the photoresistor 5, at the moment, the resistance value of the photoresistor 5 is suddenly reduced to enable the voltages at the two ends to suddenly change, as the capacitor has the effect of a passing alternating point, the voltage sudden change at the two ends of the capacitor is similar to the effect of alternating current to enable the rotating spring 11 to be electrified for a short time, the rotating spring 11 generates the similar effect of the telescopic spring 13 when electrified and is shortened, so that the inner ring 7 and the outer ring 6 are driven to relatively rotate, the two polaroids are relatively rotated, after the polaroids are relatively rotated, the light detection angles of the two polaroids are different, at the moment, less light rays irradiated on the two-way mirror 3 can be irradiated on the polaroids, and the light rays reflected again are far smaller than the light rays emitted, the light intensity reflected to another road is reduced, so that the dazzling danger of other drivers caused by the reflection of the automobile high beam by the reflector is avoided, and the dangers such as traffic accidents caused by the high beam at the turning of the road at night are effectively avoided.

The resistance value of the photosensitive resistor 5 is low in the daytime state, the current in the telescopic spring 13 is large and is in a contraction state, the sliding block 19 is disconnected from the fixed block 20, each electromagnet 14 is in a power-off state, on the contrary, the resistance value of the photosensitive resistor 5 is large in the night state, the current in the telescopic spring 13 is small and is in an extension state, and each electromagnet 14 is electrified when the sliding block 19 is in contact with the fixed block 20;
when the night is changed to daytime, the expansion spring 13 gradually contracts to enable the electromagnet 14 to be powered off, the outer ring 6 and other structures slide in the shell 1 under the action of the counterweight ball 18 until the counterweight ball 18 moves to the lowest point (the dotted line in fig. 1 is a circle where the track of the counterweight ball 18 is located when the shell 1 moves), and therefore the whole device is restored to the initial state.
When the automobile high beam lamp irradiates on the device at night, the current on the telescopic spring 13 can generate sudden change, but because the sliding block 19 and the fixed block 20 are in damping sliding connection, the relative movement speed of the sliding block 19 and the fixed block is slow, and the irradiation time of the high beam lamp is short, the circuit connection relation of the sliding block 19 and the fixed block 20 cannot be changed due to the influence of lamplight.
