[0002] With the advancement of technology, automobiles, as an important means of transportation, have also experienced rapid growth. To improve driving safety, rearview mirrors are installed on both sides of the car's exterior. However, in actual use, these exterior rearview mirrors have blind spots, meaning that when the driver looks through the exterior rearview mirror, they are unable to observe traffic conditions directly behind the car. Therefore, to improve comprehensive observation, a rearview mirror is installed inside the car. Through this mirror, the driver can observe the vehicle conditions directly behind the car and the person in the rear driver's seat.
[0003] The streaming media interior rearview mirror has two modes: streaming media mode and mirror mode. The streaming media mode uses an LCD screen to display the field of view captured by the camera. The streaming media interior rearview mirror can adjust the brightness of the display screen on the rearview mirror according to the brightness of the driving environment through calculations of the front and rear light sensors and the ECU (Electronic Control Unit) on the main board, allowing drivers and passengers to use the rearview mirror to obtain images more comfortably. The mirror mode uses the reflective layer of the surface glass to reflect the image at the rear.
[0004] In the related art, when the streaming media rearview mirror is in mirror mode, there is obvious color difference in different reflective areas of the reflector, which affects the user experience. Utility Model Content

[0022] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0023] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0024] In the related art, a display screen is provided on the back of the streaming media rearview mirror, and the area of the display screen is smaller than the area of the streaming media rearview mirror. No other equipment or coatings are provided on the streaming media rearview mirror except for the display screen. As a result, when the user is in the field of view mode, the reflectivity of the display screen area of the streaming media rearview mirror is significantly different from that of other areas. At the same time, the color of the display screen area is different from that of other areas, which affects the user experience.
[0025] In view of this, if Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a surface glass of a rearview mirror, comprising a surface glass body 1, a semi-transparent and semi-reflective film 2 being provided on the back side of the surface glass body 1, the surface glass body 1 comprising a display area 9 and a frame area 10, the frame area 10 being provided around the display area 9, and a light absorbing layer 3 being provided on the back side of the frame area 10.
[0026] In the above embodiment, the side of the assembled watch glass body 1 facing away from the driver is referred to as the back side, and the other side is referred to as the front side. Regarding the translucent semi-reflective film 2, when light strikes the translucent semi-reflective film 2, part of the light is reflected by the film 2, which can be referred to as reflected light, while the other part is transmitted by the film 2, which can be referred to as transmitted light. The light-absorbing layer 3 can be a light-shielding ink and can be applied to the side of the translucent semi-reflective film 2 facing away from the watch glass body 1. Of course, the light-absorbing layer 3 can also be formed of other light-shielding materials. A semi-transparent and semi-reflective film 2 can be connected to the back side of the surface glass body 1 by pasting. In the streaming mode, the semi-transparent and semi-reflective film 2 can transmit light, and the semi-transparent and semi-reflective film 2 on the back side of the surface glass body 1 can be penetrated by part of the light on the back side of the surface glass body 1. The formed transmitted light is irradiated onto the surface glass body 1 and irradiated into the user's eyes through the surface glass body 1. In the use of the mirror mode, the semi-transparent and semi-reflective film 2 can reflect light, and part of the light irradiated onto the surface glass body 1 through the front side of the surface glass body 1 can be reflected by the semi-transparent and semi-reflective film 2 on the back side of the surface glass body 1 to form reflected light. The reflected light enters the user's eyeball after passing through the surface glass body 1. The surface glass body 1 can also be used to protect the semi-transparent and semi-reflective film 2 to avoid scratches on the semi-transparent and semi-reflective film 2. The semi-transparent and semi-reflective film 2 is completely covered on the back side of the surface glass body 1.
[0027] In the above embodiment, the surface glass body 1 is divided into a display area 9 and a frame area 10. The display area 9 can be imaged on the surface glass body 1 through the internal liquid crystal display screen 8. The frame area 10 is annular and surrounds the display area 9. A light absorbing layer 3 is provided on the side of the semi-transparent and semi-reflective film 2 away from the surface glass body 1. The light absorbing layer 3 is arranged in the frame area 10. The light absorbing layer 3 can be covered on the semi-transparent and semi-reflective film 2 by spraying or printing, and the number of spraying or printing can be set to multiple times.
[0028] The surface glass of the rearview mirror provided in this embodiment has a semi-transparent and semi-reflective film 2 disposed on the back side of the surface glass body 1, and a light-absorbing layer 3 disposed on the back side of the semi-transparent and semi-reflective film 2 corresponding to the frame area 10 of the surface glass body 1. This allows light entering the frame area 10 and passing through the semi-transparent and semi-reflective film 2 to be absorbed by the light-absorbing layer 3 to at least a certain extent, thereby reducing the intensity of light reflected forward from the back side of the semi-transparent and semi-reflective film 2 in this area, thereby making the frame area 10 and the display area 9 have the same or a closer "black state" effect. The better reflective color performance of the semi-transparent and semi-reflective film provides users with a better user experience.
[0029] In some embodiments, the light absorbing layer 3 may have a first set distance from the edge of the surface glass body 1, that is, a gap is provided between the light absorbing layer 3 and the edge of the surface glass body 1. The width of the gap may be set to 0.1 to 0.5 mm. For example, the width of the gap may be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, and 0.5 mm. The gap may be arranged to extend along the circumference of the surface glass body 1. The inner edge of the light absorbing layer 3 may also be on the boundary between the display area 9 and the frame area 10, or may be set close to the edge of the surface glass body 1 at a distance of 0.5 mm from the boundary between the display area 9 and the frame area 10. This can prevent the light absorbing layer 3 from being sprayed to other locations due to errors in the spraying range during the spraying process. At the same time, because the internal light source is an inclined light source, the small gap between the light absorbing layer 3 and the display area 9 is not easily visible, making the front side of the surface glass body 1 smoother as a whole, the imaging more continuous, the imaging clearer in the field of view mode, and the imaging range larger.
[0030] In some embodiments, the thickness of the light absorbing layer 3 is 8 μm to 25 μm. The light absorbing layer 3 at this thickness can form a "black state" effect closer to the liquid crystal glass, making the reflective effects of the display area 9 and the frame area 10 closer.
[0031] In some optional embodiments, the semi-transparent and semi-reflective film 2 can also be set to a second set distance from the edge of the surface glass body 1, and the range of the second set distance is 0.1 to 0.5 mm. For example, the second set distance can specifically be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm and 0.5 mm.
[0032] The second set spacing can be arranged along the circumferential extension of the surface glass body 1 to prevent the cut semi-transparent and semi-reflective film 2 from having insufficient dimensional accuracy resulting in poor fitting consistency, and at the same time, the edge of the semi-transparent and semi-reflective film 2 can be prevented from being warped and separated relative to the edge of the surface glass body 1.
[0033] In the above embodiment, the first set distance and the second set distance can be set separately or in combination.
[0034] In some embodiments, a rounded corner is provided at the edge of the watch glass body 1. The rounded corner is provided on the front side of the watch glass body 1 and can be extended circumferentially along its edge. The diameter R of the rounded corner can be specifically 3 mm, and the curvature of the rounded corner cross section can be less than 90 degrees.
[0035] In this embodiment, since the rounded corner is set at the edge of the front side of the surface glass body 1, the gaps of the first set spacing and the second set spacing are both set at the edge of the back side of the surface glass body 1, so the gaps of the first set spacing and the second set spacing are both set corresponding to the rounded corner, that is, in the projection of the plane where the surface glass body 1 is located, the rounded corner can at least partially cover the gaps of the first set spacing and the second set spacing.
[0036] When the first set spacing and the second set spacing are the same in size, when a user on the front side of the assembled surface glass body 1 looks at the surface glass body 1, the light passing through the first set spacing and the second set spacing can be refracted by the rounded corners and away from the user's eyeballs, thereby preventing the user from viewing the rear shell or light source through the first set spacing and the second set spacing. Instead, the light irradiated to the front side of the surface glass body 1 is reflected by the semi-transparent and semi-reflective film 2 and the light-absorbing layer 3 and refracted by the rounded corners to illuminate the user's eyeballs, thereby achieving the effect of removing the frame, avoiding affecting the integrity of the imaging, and making the imaging more beautiful.
[0037] When the first set spacing is smaller than the second set spacing, when the user on the front side of the assembled surface glass body 1 views the surface glass body 1, the light passing through the first set spacing is directly irradiated to the rounded corner position, which can prevent the light from irradiating the edge of the semi-transparent and semi-reflective film 2, and the light irradiated through the first set spacing can be refracted through the rounded corner and away from the user's eyeball, preventing the user from viewing the shell or light source behind it through the first set spacing. Instead, the light irradiated to the front side of the surface glass body 1 is reflected by the semi-transparent and semi-reflective film 2 and the light-absorbing layer 3 and refracted through the rounded corner to illuminate the user's eyeball position, thereby achieving the effect of removing the frame, avoiding affecting the integrity of the imaging, and making the imaging more beautiful.
[0038] When the first set spacing is greater than the second set spacing, when the user on the front side of the assembled surface glass body 1 looks at the surface glass body 1, a part of the light after passing through the first set spacing is irradiated by the semi-transparent and semi-reflective film 2, and then the semi-transparent and semi-reflective film 2 reflects and transmits the light after passing through the first set spacing, and the reflected light returns to the original path, and the transmitted light and another part of the light are irradiated to the rounded corner position, and are refracted away from the user's eyeballs after being refracted by the rounded corner, so as to prevent the user from viewing the shell or light source behind the first set spacing and the second set spacing at the rounded corner. Instead, the light irradiated to the front side of the surface glass body 1 is reflected by the semi-transparent and semi-reflective film 2 and the light-absorbing layer 3, and is refracted by the rounded corner to illuminate the user's eyeball position, thereby achieving the effect of removing the frame, avoiding affecting the integrity of the imaging, and making the imaging more beautiful.
[0039] At the same time, the rounded corners on the front side of the watch glass body 1 can prevent the driver from being bumped during use, and can also prevent the driver from being injured in an emergency.
[0040] The present invention also provides a vehicle streaming media rearview mirror, comprising a housing 4, a polarizer 5, an optically transparent adhesive 6, and a double-sided adhesive 7. A polarizer 5 is attached to a display area 9 on the back side of a surface glass body 1. The polarizer 5, whose full name is polarizer, is an important component of liquid crystal display imaging. The polarizer 5 is attached to a semi-transparent and semi-reflective film 2 via an optically transparent adhesive 6. The optically transparent adhesive 6 can be an epoxy adhesive with the characteristics of light color, high transparency, good bonding properties, and excellent high and low temperature performance. It can also be an OCA (Optically Clear Adhesive), a special adhesive used to bond transparent optical components (such as lenses, etc.). OCA is required to be colorless and transparent, have a light transmittance of more than 95%, good bonding strength, be curable at room temperature or medium temperature, and have small curing shrinkage. The size of the polarizer 5 can be slightly larger than the display area 9, that is, the length and width of the polarizer 5 can exceed the boundary of the display area 9. When the rear liquid crystal display screen 8 is projected, light will not be irradiated to a position beyond the display area 9, and the part of the polarizer 5 that exceeds the display area 9 is blocked by the light absorbing layer 3.
[0041] In the above embodiment, when the user on the front side of the surface glass body 1 uses reflection to view the rear view, the light-absorbing layer 3 imitates the reflectivity and color of the polarizer 5. After cooperating with the semi-transparent and semi-reflective film 2, the front side of the surface glass body 1 can appear more complete. The △E (total color difference) of the color of the semi-transparent and semi-reflective film 2 combined with the light-absorbing layer 3 and the color of the semi-transparent and semi-reflective film 2 combined with the polarizer 5 is less than 1. Among them, the smaller the value of △E, the closer the two colors are. Under the premise of minimizing the color difference, the same reflection effect can also be achieved.
[0042] In some optional embodiments, the edge of the surface glass body 1 can be arranged flush with the edge of the shell 4, that is, in the projection on the plane where the surface glass body 1 is located, the projection of the surface glass body 1 coincides with the projection of the shell 4, so that when the user views the surface glass body 1, the shell 4 on the back side will not protrude beyond the range of the surface glass body 1, so that the driver can only see the surface glass body 1, making the surface more neat and beautiful.
[0043] Optionally, the size of the shell 4 can be smaller than the size of the surface glass body 1, that is, the length and width of the shell 4 can be smaller than the length and width of the surface glass body 1, respectively, so that the shell 4 is hidden on the back side of the surface glass body 1, so that the shell 4 on the back side cannot be seen when viewing from the front side of the surface glass body 1, making the overall front side of the surface proportion more neat and beautiful.
[0044] In some optional embodiments, the shell 4 is connected to the side of the light absorbing layer 3 facing away from the surface glass body 1, wherein the side of the light absorbing layer 3 facing the shell 4 can be sprayed with glue, and the light absorbing layer 3 can be bonded to the end face of the shell 4 by glue. A shock-absorbing layer can also be provided between the light absorbing layer 3 and the shell 4. The shock-absorbing layer can be made of foam material, and glue can be applied to the shock-absorbing layer. The shell 4 is bonded to the light absorbing layer 3 through the shock-absorbing layer to connect the surface glass body to the shell 4. At the same time, the shock-absorbing layer absorbs energy to prevent the surface glass body 1 or the light absorbing layer 3 from separating from the shell 4 due to the bumps of the vehicle during use, thereby preventing damage to the rearview mirror.
[0045] In some optional embodiments, when the surface glass body 1 is bonded to the shell 4, the semi-transparent and semi-reflective film 2 on the back side of the surface glass body 1 can be bonded to the polarizer 5 with an optically transparent adhesive 6, and then the polarizer 5 is bonded to the parts on the shell 4, such as the liquid crystal display 8 bonded to the shell 4. The liquid crystal display 8 fixed in the shell 4 is used to fix the surface glass body 1, so there is no need to fix it on the shell 4 in a conventional way, thereby reducing the amount of adhesive material used.
[0046] The gap between the shell 4 and the surface glass body 1 can be sealed with double-sided tape 7, that is, at the edge of the back side of the surface glass body 1, a ring-shaped double-sided tape 7 is arranged along the plane of the surface glass body 1, and the double-sided tape 7 is bonded to the light-absorbing layer 3, and the other is bonded to the end face of the shell 4. Since the double-sided tape 7 is not responsible for the load-bearing capacity of the surface glass body 1, it is allowed to select a double-sided tape 7 with a smaller cross-sectional area.
[0047] Double-sided tape 7 prevents dust from entering through the gap between the surface glass body 1 and the housing 4. It also prevents light from entering through the gap between the surface glass body 1 and the housing 4, causing light leakage and affecting the imaging effect. Furthermore, since double-sided tape 7 no longer provides the primary adhesive force for securing the surface glass body 1, the width of double-sided tape 7 can be reduced to just enough to block the gap between the surface glass body 1 and the housing 4. This reduces the amount of double-sided tape 7 used, resulting in a lower overall weight and higher economic efficiency.
[0048] Furthermore, since the surface glass body 1 is bonded to the liquid crystal display screen 8 through the semi-transparent and semi-reflective film 2, the partial light-absorbing layer 3, the optically transparent adhesive 6, and the polarizer 5, there is no air layer in the middle, which reduces the thickness of the rearview mirror. At the same time, the EC glass is removed, which reduces the overall weight of the rearview mirror and further reduces the thickness of the rearview mirror, making the overall appearance more beautiful, occupying less space, and reducing the manufacturing cost.
[0049] An embodiment of the present utility model also provides a vehicle, including a vehicle streaming media rearview mirror, wherein the vehicle streaming media rearview mirror is arranged in the vehicle's cab and at the upper end of the front windshield, the vehicle streaming media rearview mirror can be connected to the windshield through a suction cup, and can also be connected to the roof through a connecting arm, and the power cord through the roof can supply power to the vehicle streaming media rearview mirror through the connecting arm. At the same time, in the streaming media mode of the vehicle streaming media rearview mirror, the camera at the front or rear end of the vehicle can be connected to the vehicle streaming media rearview mirror through an electrical signal, so that the image of the front or rear end of the vehicle is transmitted to the vehicle streaming media rearview mirror, and when the streaming media mode is canceled, the rear view can be seen through the reflection of the mirror, thereby realizing the use of the field of view mode.
[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
