[0002] The glass windows of existing high-speed transportation vehicles such as airplanes and trains are all sealed and fixed, and are usually only used for lighting. They are often covered by curtains to achieve two conditions: light-transmitting and light-proof. This method has technical defects and cannot adjust the light transmittance as needed, and cannot meet the comfort of passengers when riding. In special circumstances, such as when the aircraft is preparing to take off and landing and the curtains are required to be opened, passengers in some seats often refuse to cooperate, which also poses potential risks to the safety of the vehicle during driving.

[0003] Patent CN202022776395.8 discloses a dimming glass window and a vehicle, the dimming glass window includes a glass unit, including an inner glass component and an outer glass component arranged relatively, a storage space is formed between the inner glass component and the outer glass component; a touch function layer and a dimming function layer are arranged between the inner glass component and the outer glass component, the touch function layer is located on the inner side of the dimming function layer; a control unit is located in the storage space and connected to the touch function layer and the dimming function layer; a dimming controller is arranged outside the glass unit, the dimming controller is connected to the control unit through a wire, so as to cooperate with the control unit, the touch function layer and the dimming function layer to realize the light transmittance adjustment of the dimming glass window. The dimming glass window and the vehicle improve the problem that the FPC connecting the existing dimming window function layer and the control module is very easy to be damaged by the outside during the window installation and subsequent maintenance. However, the shortcomings of this patent are that the production principle is relatively complicated, and the light-blocking materials that can be used between glass layers are often expensive, resulting in high production costs. Although the PDLC (polymer dispersed liquid crystal) with a mature industrial chain has a lower cost, its performance is average and cannot be continuously adjusted. Utility Model Content

[0004] In order to overcome the shortcomings of the above-mentioned prior art, the utility model provides an electrically controlled glass window device with adjustable light transmittance that can finely and continuously adjust the light transmittance of the glass window, can adjust the light transmittance of the glass window individually or uniformly, improves the riding environment comfort, is clean and environmentally friendly, saves electricity, and can improve the safety of the driving process.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0006] An electrically controlled glass window device with adjustable transmittance comprises an adjustment component, an adjustable polarizer and a fixed polarizer, wherein the adjustment component comprises a motor, an adjustment knob, a driving shaft, a meshing driving gear and a driven gear frame, wherein the fixed polarizer is attached to one side of the glass window, and the driven gear frame is rotatably mounted on the other side of the glass window, and the adjustable polarizer is fixed in the driven gear frame and is parallel to the fixed polarizer; one end of the driving shaft is threadedly connected to the driving gear, and the other end is connected to the output port of the motor, and the motor is provided with an adjustment knob, and the adjustment knob is mounted on the inner side of the vehicle.

[0007] In the utility model, when installing the adjustment component, it is preferred to adopt an installation method in which the gear teeth of the driven gear frame, the driving gear, the driving shaft and the motor are hidden inside the vehicle shell; in order to achieve the effect of finely and continuously adjusting the light transmittance of the glass window, the radius of the driving gear should be smaller than the radius of the driven gear frame; the adjustable polarizer and the fixed polarizer are preferably circular polarizers, and the matrix is ​​preferably PMMA and polymer film.

[0008] As a further technical improvement, the adjustment assembly further includes a plurality of master control switches disposed inside the vehicle, the master control switches being electrically connected to the motor. The master control switches should be located in a position that is easy for crew members to operate, so that crew members can uniformly control the light transmittance of all glass window devices in the vehicle under special circumstances such as take-off and landing.

[0009] As a further technical improvement, a layer of radiation-proof film is installed between the adjustable polarizer and the glass window. The radiation-proof film contains a pressure-sensitive adhesive layer, an anti-ultraviolet isolation layer, a metal heat-insulating film layer and an explosion-proof layer, etc., which can play the role of radiation protection, UV protection and heat insulation.

[0010] As a further technical improvement, a plurality of small solar panels are fixedly mounted on one side of the driven gear frame located outside the vehicle, and a battery is also provided inside the motor, and the small solar panels are connected to the battery inside the motor. The small solar panels can provide backup power for the glass window device, and in the event of a power outage in the vehicle due to an emergency, the glass window device can be prevented from being at a light transmittance that is not conducive to driving safety; solar charging is clean and environmentally friendly, and can also save power loss in the vehicle.

[0011] The working principle of this utility model:

[0012] From the polarization characteristics of light and Malus's law, it can be known that natural light with an intensity of I0 will be converted into linearly polarized light after passing through a polarizer (polarizer). At this time, the light intensity I1 is half of I0; the outgoing light intensity I2 obtained after passing through the second polarizer (analyzer) is related to the angle α between the polarization directions of the two polarizers, which can be expressed by the formula:

[0013]

[0014] It can be seen that the range of the outgoing light intensity I2 after passing through the two polarizers is between 0 and The change of the output light intensity I2 depends on the angle α between the polarization directions of the two polarizers. When in use, by adjusting the knob or the master switch, the smaller active gear can be driven to drive the larger driven gear frame to perform fine angle adjustment, thereby changing the relative polarization directions of the adjustable polarizer and the fixed polarizer to achieve the effect of adjusting the light transmittance of the glass window, wherein the adjusting knob can adjust the glass window device on the seat individually, and the master switch can uniformly adjust all the glass window devices on the vehicle. If the vehicle is an airplane or train that is exposed to sunlight for a long time during driving, the small solar panel can store electricity for the motor of the adjustment device to save power consumption, and can also avoid the risk of strong light exposure or insufficient light and inability to adjust the light transmittance due to power outage of the vehicle in an emergency.

[0015] Compared with the prior art, the advantages and beneficial effects of the utility model are as follows:

[0016] 1. The utility model can finely and continuously adjust the light transmittance of the glass window, and the light entering effect is uniform and eye-protecting.

[0017] 2. The utility model allows the crew to uniformly control the light transmittance of the glass windows through the master control switch, thereby preventing passengers from failing to cooperate with the adjustment when necessary, thereby improving safety during driving.

[0018] 3. The utility model contains a layer of radiation protection film, which can block most of the radiation and ultraviolet rays, make the ambient temperature in the cabin or compartment suitable, and improve the explosion-proof performance.

[0019] 4. The utility model is also provided with a small solar panel, which can store electricity for the motor of the adjustment device to save power consumption, and can also avoid the risk of strong light exposure or insufficient light and inability to adjust the transmittance due to power failure of the vehicle in an emergency.
