Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
Fig. 1 is a schematic view of a structure of a windshield for a vehicle in cooperation with an a-pillar 30 according to one embodiment of the present invention. Fig. 2 is a schematic structural view of a windshield for a vehicle according to one embodiment of the present invention. In fig. 1, a indicates a front windshield inner edge line, B indicates a field of view line, and the direction of the vertical upward arrow indicates the front of the vehicle. As shown in fig. 1, and also referring to fig. 2, the present invention provides a windshield for a vehicle, generally comprising a body 10 and a color changing clear glass 20. The main body 10 is made of transparent glass. The color-changing light-transmitting glass 20 is connected to an edge of the body 10 at one side and an edge of an a-pillar 30 or a back door trim of a vehicle at the other side, and transparency of the color-changing light-transmitting glass 20 is controllably changed.
The windshield provided by the embodiment comprises a main body 10 and a color-changing light-transmitting glass 20, wherein the main body 10 is generally transparent, the color-changing light-transmitting glass 20 is connected between the main body 10 and an A column 30 or between the main body 10 and a door trim, and the transparency of the color-changing light-transmitting glass 20 can be controllably changed, for example, when a driver needs to increase the visual field range and reduce the obstacle angle during driving, the transparency of the color-changing light-transmitting glass 20 can be controlled to be increased. The transparency of the color-changing transparent glass 20 can be controlled in various ways, such as manual control by setting a manual switch or automatic control after sensing information by a sensor. Therefore, the windshield provided by the application can reduce the barrier angle of a driver in the driving process and improve the driving safety.
In a specific embodiment, the transparency of the color changing translucent glass 20 is changed to increase the transparency when the driving speed of the vehicle exceeds a preset speed value. When the driving speed of the vehicle exceeds the preset speed value, the driver needs a wider visual field range for driving safety, so that the transparency of the color-changing transparent glass 20 is controlled to change when the driving speed exceeds the preset speed value, and the transparency is continuously increased to 100% along with the acceleration of the driving speed of the vehicle. Preferably, when the running speed of the vehicle is less than or equal to the preset speed value, the transparency of the color-changing transparent glass 20 is less than the preset value, and the preset value is 20%, so that the edge of the interior trim panel 31 can be shielded, and the appearance attractiveness of the vehicle is improved. Therefore, the windshield combines the color-changing transparent glass 20 with the running speed of the vehicle, can reduce the barrier angle in the running process, can more easily meet the requirement of the barrier angle of the A column 30, and reduces the process requirement on the interior trim and the vehicle body; the appearance quality requirement (shielding the edge of the interior part) can be ensured in the parking stage, so that the obstacle angle can be reduced and the appearance of the vehicle can be considered.
In a specific embodiment, the color-changing light-transmitting glass 20 includes a light-transmitting glass 21 and a color-changing layer 22 disposed on the light-transmitting glass 21. In the present embodiment, the photochromic layer 22 of the photochromic light-transmitting glass 20 is attached to the outer surface of the light-transmitting glass 21.
Fig. 3 is a block diagram of a color-changing light-transmitting glass for a windshield of a vehicle according to one embodiment of the present invention. In one particular embodiment, as shown in fig. 3, the tinted transparent glass 20 includes a plurality of stacked transparent glasses 21 and at least one tinted layer 22. In this embodiment, the discoloring layer 22 may be disposed between two layers of transparent glass 21, and may also be attached to the outer surface of the transparent glass 21, preferably, the discoloring layer 22 is disposed between two layers of transparent glass 21, so that the service life of the discoloring layer 22 may be prolonged.
In a specific embodiment, the discoloration layer 22 includes a polymer dispersed liquid crystal film, the polymer dispersed liquid crystal film is connected to a vehicle controller of the vehicle, the vehicle controller collects a driving speed of the vehicle, and when the driving speed exceeds a preset speed value, the vehicle controller controls the transparency of the discoloration layer 22 to increase with the increase of the driving speed until the transparency is consistent with the transparency of the main body 10. In a preferred embodiment, the vehicle controller controls the transparency of the color changing layer 22 to change by outputting a first control signal when the driving speed of the vehicle exceeds a preset speed value, the vehicle powers on the color changing layer 22 according to the first control signal, and outputs a second control signal when the driving speed of the vehicle is less than or equal to the preset speed value, and the vehicle powers off the color changing layer 22 according to the second control signal. The principle of the change in transparency of the color-changing layer 22 is that a polymer-dispersed liquid crystal film is formed by dispersing liquid crystals in a collection of organic solid polymers in small droplets of micron order, and since the optical axis of the small droplets composed of liquid crystal molecules is in a free direction, the refractive index thereof does not match the refractive index of the matrix, and when light passes through the matrix, the light is strongly scattered by the droplets to assume an opaque milky-white or translucent state. Application of an electric field can adjust the optical axis orientation of the liquid crystal droplets, which when index matched, appear transparent. When the electric field is removed, the liquid crystal droplets restore the original state of astigmatism.
With continued reference to fig. 3, in one particular embodiment, a polyvinyl butyral film 23 is also disposed between the coloration layer 22 and the transparent glass.
In one embodiment, the color-changing transparent glass 20 is in the shape of a vertical bar and is disposed at both sides of the body 10. In a preferred embodiment, the color-changing transparent glass 20 is disposed around the body 10.
In a specific embodiment, the width of the color-changing transparent glass 20 is 1-10mm, and preferably, the width of the color-changing transparent glass 20 is 6 mm. With reference to fig. 1, by taking the front windshield as an example, when the transparency of the color-changing translucent glass 20 is small, for example, less than 20%, the edge line of the front view of the driver is the edge of the main body 10, and when the transparency of the color-changing translucent glass 20 is increased, for example, 80%, the edge line of the front view of the driver becomes the outer edge of the color-changing translucent glass 20, thereby reducing the obstacle angle, improving the driver's visible area, and increasing the driving safety.
In a specific embodiment, the preset speed value is 20-60km/h, preferably 40 km/h.
Fig. 4 is a block flow diagram of a control method for a windshield of a vehicle according to one embodiment of the invention. As shown in fig. 4, the present invention also provides a control method for a windshield provided in any one of the above embodiments, which generally includes:
step S10: collecting the running speed of a vehicle;
step S20: judging whether the running speed exceeds a preset speed value or not;
step S30: if so, controlling the transparency change of the color-changing transparent glass.
The present embodiment provides a control method for the windshield, specifically, the driving speed of the vehicle is firstly collected, and when the driving speed exceeds a preset speed value, the transparency change of the color-changing transparent glass 20 is controlled. Preferably, when the driving speed of the vehicle is less than or equal to the preset speed value, the driver may overcome the obstacle angle by turning the head, and thus the transparency of the color-changing translucent glass 20 may be set to be less than the preset value, preferably 20%. More preferably, when the driving speed of the vehicle is less than or equal to the preset speed value, the transparency of the color-changing light-transmitting glass 20 is zero, so that the interior trim boundary can be covered. When the driving speed exceeds the preset speed value, the reaction time left to the driver is shortened, so that the transparency of the color-changing light-transmitting glass 20 is controlled to be changed, preferably, the transparency is increased along with the increase of the driving speed until the transparency reaches 100 percent, namely, the transparency is completely realized, thereby reducing the driving obstacle angle of the driver.
The invention also provides a vehicle which generally comprises the windshield provided by any one of the embodiments, wherein the transparency of the edge of the windshield of the vehicle can be changed along with the vehicle speed, so that the driving vision of a driver and the vehicle aesthetic measure can be considered.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
