Electronic sun shield and electronic sun shield system applied to vehicle, and vehicle

Abstract

The invention discloses an electronic sun shield applied to a vehicle. The electronic sun shield comprises a polymer dispersed liquid crystal dimming film, wherein the polymer dispersed liquid crystaldimming film is provided with a current input end and regulates the light transmittance of the polymer dispersed liquid crystal dimming film on the basis of the change of a current input by the current input end, and the polymer dispersed liquid crystal dimming film is at least arranged on the front windshield of the vehicle. In addition, the invention also discloses an electronic sun shield system which is applied to the vehicle. The electronic sun shield system comprises the above electronic sun shield, a direct current power supply, a control module and an inversion control module independently connected with the direct current power supply, the control module and the current input end of the polymer dispersed liquid crystal dimming film, wherein the inversion control module converts adirect current output from the direct current power supply into an alternating current, and outputs alternating currents of different magnitudes on the basis of a control signal transmitted by the control module to regulate the light transmittance of the polymer dispersed liquid crystal dimming film. In addition, the invention also discloses a vehicle with the above electronic sun shield system.

Description

technical field [0001] The invention relates to an electronic sunshade device, a system and a vehicle with the system, in particular to an electronic sunshade device, a system for adjusting light transmittance through a polymer, and a vehicle with the system. Background technique [0002] At present, the inside of the front windshield of the vehicle is respectively provided with a sun visor at the driver's place and the co-pilot's place, and the sun visor can rotate around an axis. When the main and co-pilots feel that the light outside is strong, they can turn over the sun visor to block the sun. Generally, the two sun visors are plastic pieces covered with fabric. [0003] This kind of sun visor is composed of plastic, cloth and other materials, and the main and co-drivers need to manually flip it over to realize the sun visor function. When the driver manually flips the sun visor while the vehicle is running, it will distract the driver's attention and pose a safety haza...

AI Technical Summary

Problems solved by technology

combine figure 1 and figure 2 It can be seen that the sun visor in the prior art needs to be manually operated to realize the sun shading function. On the one hand, the operation is not convenient, and on the other hand, it increases safety risks. For example, the driver manually flips the sun visor while the vehicle is running, which will distract the driving staff attention, there are potential safety hazards
