[ anti-glare Structure ]
In connection with fig. 1, the first aspect of the present application proposes an anti-glare structure comprising a front window 10, a light source positioning member 20, a photosensitive member 30, and a controller, wherein the front window 10 is configured to include a plurality of visible regions, each of which can independently change its light transmittance.
The front window 10 includes an electrochromic layer configured to change its light transmittance upon application of different voltages, and a glass protective layer on either side of the electrochromic layer. Specifically, the electrochromic layer comprises a first electrode, a liquid crystal layer and a second electrode, the liquid crystal layer is arranged between the first electrode and the second electrode, and the controller is used for controlling the voltage between the first electrode and the second electrode so as to change the light transmittance of the liquid crystal layer.
Therefore, the light transmittance of each visual area can be changed locally, and the interference of strong light on the visual field of a driver is reduced.
As shown in fig. 1, the light source positioning member 20 is disposed on the inner side of the front window 10, and is used for positioning the direction of the light source directed to the front window 10, preferably disposed directly above the driver, so that the light source positioning member 20 is located at the same position as the driver, and the light sources with different angles on the left and right sides detected by the light source positioning member 20 are almost the same angle in the field of view of the driver, which is beneficial to matching the photosensitive area of the photosensitive member 30 with the visible area of the front window 10.
It should be understood that, in the case that the angle of the driver is similar to the angle of the light source positioning member 20, and thus, the angle of the light source detected by the light source positioning member 20 is almost similar to the angle actually observed by the driver, when the difference occurs, the visual area and the photosensitive area are re-matched by the controller, for example, the visual area where the transmittance of light is changed, which is observed by the driver, deviates from the position where the light source actually exists by one layer in height downwards, and then the visual area is controlled to be matched with the photosensitive area above the original photosensitive area, that is, the whole is shifted upwards by one layer, so that the corresponding relationship between the photosensitive area and the visual area can be changed again.
The photosensitive member 30 is provided inside the light source positioning member 20 for detecting light passing through the light source positioning member 20, and the controller is electrically connected to the front window 10 and the photosensitive member 30.
As shown in fig. 2, the light source positioning member 20 includes a hemispherical structure 21, the hemispherical structure 21 having a photosensitive area 22, a plurality of micro-hole channels 23 being provided in the photosensitive area 22, a first end of each micro-hole channel 23 being directed to the same focal point on a concave side of the hemispherical structure 21, and a second end being directed to the front of the front window 10.
Thus, the plurality of micro-hole channels 23 can detect the light rays emitted from the left and right directions and the up and down directions of the driver, the plurality of micro-hole channels 23 are arranged in a central symmetry and tightness manner, and the inner wall of each micro-hole channel 22 is provided with a light absorption coating, so that the light rays have the maximum light intensity when passing through the second end along the axis of the first end of the micro-hole channel 22.
Only when the line connecting the light source and the focal point coincides with the micro-porous channel, the light source passes through to the micro-porous channel 23, or a large part of the light is directed to the photosensitive member 30 through the micro-porous channel 22.
Further, the photosensitive member 30 is configured to include a plurality of light sensing regions, each of which corresponds to at least one light sensing region, and the controller 30 is configured to adjust the light transmittance of each of the light sensing regions according to the illumination intensity of the light sensing region.
As described in connection with fig. 3, the photosensitive member 30 includes a plurality of photosensitive sensors attached to the ends of the micro-porous channels 23, each of which can independently transmit an electric signal to the controller, so that when light passes through the micro-porous channels 23, the photosensitive sensors transmit current signals of different intensities to the controller according to the intensity of illumination.
As shown in connection with fig. 4, a plurality of micro-porous channels 23 are arranged in an array around a focal center, optionally, the included angle between the uppermost micro-porous channel 23 and the lowermost micro-porous channel is 120 °. As shown in fig. 1 and 5, the width direction of the front window 10 is defined as a first direction, the height direction is defined as a second direction, the plurality of visible regions are arranged in a matrix along the first direction and the second direction, and the light-sensing regions are also arranged in a matrix along the first direction and the second direction.
Referring to fig. 6, the front windshield is divided into four regions including a visible region a1, a visible region a2, a visible region a3, and a visible region a4, wherein when the light source a is lit, its corresponding angle changes the light transmittance of the visible region a1, when the light source B is lit, its corresponding angle changes the light transmittance of the visible region a2, when the light source C is lit, its corresponding angle changes the light transmittance of the visible region a3, and when the light source D is lit, its corresponding angle changes the light transmittance of the visible region a 4.
As shown in fig. 7, the front windshield is divided into four areas including a visible area b1, a visible area b2, a visible area b3, and a visible area b4, the light source a, the light source b, the light source c, and the light source d are respectively located at different heights corresponding to different angles with respect to the light source positioning member 20 in the height direction, when the light source a is lit, the light transmittance of the visible area b1 is changed, when the light source b is lit, the light transmittance of the visible area b2 is changed, when the light source c is lit, the light transmittance of the visible area b3 is changed, and when the light source d is lit, the light transmittance of the visible area b4 is changed.
It will be appreciated that the smaller the volume of the photosensor, the larger the area of the micro-porous channels 23, the higher the positioning resolution of the light angle, for one or more of the plurality of micro-porous channels 23 corresponds to a light sensing region. Preferably, the micro-hole channels 23 and the light sensing areas are in one-to-one correspondence, for example, when the leftmost light sensing area transmits a current signal to the controller, it indicates that light is incident in the leftmost micro-hole channel 23 of the plurality of micro-hole channels 23.
In an alternative embodiment, the front window 10 is divided into a first area in front of the driver and a second area in front of the co-driver, wherein the area of the viewable area in the first area is smaller than the area of the viewable area in the second area.
Specifically, the area of the visible area in the first area is one fourth of the area of the visible area in the second area, so that the number of the visible areas in the first area is large, the resolution is high, the light source can be effectively shielded, and the remaining areas of the other areas can keep good light transmittance.
[ anti-glare method ]
The second aspect of the present application proposes a technical solution, an anti-glare method, using the above anti-glare structure, characterized by comprising the steps of:
step S1, comparing the illumination intensities of all light sensing areas at the current moment ta, and grading the illumination intensity of each light sensing area;
step S2, setting the corresponding visible area as light transmittance of different levels according to the illumination intensity level of each light sensing area at the current moment ta;
wherein, in all light sensing areas, the illumination intensity with the largest occurrence number is defined as basic illumination intensity, and the illumination intensity which is larger than the basic illumination intensity is divided into 1-n grades (n > 3), wherein the light transmittance of the visible area corresponding to the 1-grade illumination intensity is 100%.
In the view in front of the vehicle, the illumination intensity of most of the areas can represent the brightness of the current environment, and therefore, the illumination intensity defined as the base illumination intensity which occurs most in all the light sensing areas, wherein the area higher than the base illumination intensity is regarded as the area with the light source, and the area with the light source is classified according to the illumination intensity.
Alternatively, the brightest luminance received in the light-sensing region is taken as the highest level, e.g. the illumination of the sun at a certain moment, divided into ten levels between the highest illumination intensity and the base illumination intensity, wherein the light transmittance is increased or decreased by 10% every crossing one level.
In a preferred embodiment, a plurality of light sensing areas with illumination intensities close to and at adjacent positions are defined as light source areas, and a light sensing area at the center of the plurality of light sensing areas is defined as the light source center;
wherein the visible area corresponding to the center of the light source is a shielding area;
the illumination intensity change and the position change of the light source center at the previous time ta-1 and the current time ta are obtained, and the visible area of the shielding area in the moving direction of the light source center is defined as an extension area according to the position change direction and the speed, wherein the light transmittance of the extension area is smaller than 100%.
Since there is more than one light sensing area illuminated by one light source, a plurality of light sensing areas affected by one light source, that is, light sensing areas with adjacent positions and similar illumination intensities are defined as one light source area, and a light sensing area at a central position is defined as the center of the light source, which is beneficial to reducing the calculation amount and accurately tracking the movement and brightness variation of the light source.
The visible area corresponding to the center of the light source is a shielding area, the light transmittance of the shielding area is smaller than that of other areas, and the strong light is weakened by shielding the illumination of the light source by reducing the light transmittance.
Further, in order to give the driver a better visual experience, the light source is smoothly transited and shifted in the visual field, and an extension area is arranged in the moving direction of the center of the light source, and the light transmittance of the extension area is less than 100%.
In a specific embodiment, the position of the center of the light source at any moment and the change of the illumination intensity are recorded, the visible area of the shielding area in the moving direction of the center of the light source is defined as an extension area according to the position change direction and the speed, the light source A moves along a straight line and approaches the front window 10 continuously in the process of t1-t4, the angle of the light source A gradually changes in the process of moving from t1 to t4 as shown in fig. 9, and therefore, the light sensing area is gradually shifted, alternatively, the light source A moves in the transverse direction and also moves in the height direction at t3 and t4, and the light intensity received by the light sensing area becomes larger due to the decrease of the distance, the light transmittance gradually decreases and the light transmittance changing range gradually increases at t1 to the right side as shown in fig. 10.
In a preferred embodiment, the extended area comprises at least three visible areas distributed in the direction of movement of the centre of the light source, the three visible areas being arranged to progressively increase in light transmittance in a sequence away from the centre of the light source.
In a specific embodiment, in the process of moving the light source a from the time t1 to the time t4, at the time t1, as shown in fig. 10, the region corresponding to t1 is a shielding region, and the regions corresponding to t2, t3, and t4 are extension regions. In a specific embodiment, when the light transmittance of the t1 region is 70%, the light transmittance of t2, t3, and t4 is 75%, 80%, 85%, respectively.
Further, the extending direction is divided into a first direction and a second direction, and the extending region includes a visible region extending in the first direction and a visible region extending in the second direction, wherein the number of visible regions extending in each direction, the light transmittance, and the component of the light source center position change vector in the first direction and the second direction are correlated.
Since the light source generates a component in the second direction, a visual area of varying perspective extends longitudinally downwards in the area t3, t3 comprising two visual areas.
Optionally, the ratio of the light transmittance of the extension area to the light transmittance of the shielding area is a, the position change speed of the center of the light source is x, wherein a=bx, and b is a constant.
It will be appreciated that the ratio of the light transmittance of the extended region to the light transmittance of the blocked region is positively correlated with the rate of change of the light source center, and that the greater the rate of movement of the light source center, the closer the light transmittance of the extended region and the blocked region.
In combination with the above embodiment, the windshield in front of the driver is set as a plurality of visible areas, the light transmittance of each visible area is variable, the light source which is directed to the driver is positioned by the light source positioning component, so that the corresponding relation between each perspective area of the front windshield and the light source is established, when the light source is directed to the driver from the corresponding angle, the light transmittance of the corresponding visible area changes, strong light is not so dazzling in the visual field of the driver through reducing the light inlet quantity, and the other parts except the strong light still keep good light transmittance, so that the driver can observe objects in the other areas, and the visual field of the driver is clear and bright on the basis of ensuring that the driver is not dazzled.
