[0002] The rearview mirror is one of the important accessories of a car. Through the rearview mirror, the driver can understand the road conditions around the car in real time. To ensure that the car owner can clearly observe the road conditions, most of the existing rearview mirrors are display devices with display screens to display the road conditions around the car in real time. However, there are many circuits around the display screen. The existing rearview mirror can see components such as wiring harnesses and cables through the cover plate. To solve the problem of being able to see the wiring harnesses and cables, the existing rearview mirror will set a black silk screen on the edge of the cover plate to avoid leakage of the wiring harnesses and cables. However, the setting of the black silk screen will cause the edge of the rearview mirror to have an obvious black edge, affecting the car owner's user experience.

[0003] Therefore, a rearview mirror is needed urgently to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of the utility model is to provide a rearview mirror, which can not only shield the wiring harness and wiring around the display screen, but also has no obvious black edges on the edges of the rearview mirror, thereby providing the car owner with a good user experience.

[0005] To achieve this purpose, the utility model adopts the following technical solutions:

[0006] A rearview mirror, comprising:

[0007] case;

[0009] The display assembly is located in the shell, and includes a display screen and a backlight module arranged in sequence. The display screen is connected to the connection layer. The display screen is used to display information, and the backlight module is used to provide backlight for the display screen.

[0010] As a preferred technical solution for the rearview mirror, the thickness of the cover plate is 1.8 mm-2.0 mm; and / or the thickness of the reflective polarizing film is 0.073 mm-0.080 mm.

[0011] As a preferred technical solution for the rearview mirror, the backlight module includes a light source, a light guide plate, an optical film and a plastic frame, and the light source is distributed around the display screen.

[0012] As a preferred technical solution for the rearview mirror, the cover assembly and the display assembly are bonded together using a full bonding process.

[0013] As a preferred technical solution for the rearview mirror, the width of the ink layer is 3mm-8mm.

[0014] As a preferred technical solution of the rearview mirror, the connecting layer is a transparent adhesive layer.

[0015] As a preferred technical solution for the rearview mirror, the transparent adhesive layer is optical adhesive.

[0016] As a preferred technical solution of the rearview mirror, the rearview mirror also includes a photosensitive element, and the photosensitive element is used to adjust the brightness of the rearview mirror.

[0017] As a preferred technical solution for the rearview mirror, the photosensitive element is connected in series to the power supply circuit of the backlight module, and the resistance value of the photosensitive element can change with the light intensity.

[0018] As a preferred technical solution of the rearview mirror, the rearview mirror further includes a touch sensing module, and the touch sensing module is located between the connecting layer and the display screen.

[0019] The beneficial effects of the utility model are:

[0020] The rearview mirror of the utility model arranges a reflective polarizing film between the cover plate and the ink layer. Since the reflective polarizing film can reflect light, the cover plate will have a certain reflection intensity after being attached to the reflective polarizing film, and the light emitted by the ink layer will also be reflected, thereby visually weakening the existence of the ink layer. By adjusting the reflectivity of the reflective polarizing film, the existence of the black edge can be visually invisible. The reflective polarizing film uses an RPM film. Since the reflectivity of the RPM film to light is greater than 45%, which is higher than other types of reflective polarizing films, the visual weakening effect of the black edge is more obvious, so that the ink layer is basically invisible visually.

[0029] like Figure 1As shown in , this embodiment provides a rearview mirror, including a housing (not shown in the figure), a cover assembly 1 and a display assembly 2. The cover assembly 1 and the display assembly 2 are placed in the housing from top to bottom, wherein the cover assembly 1 includes a cover 11, a reflective polarizing film 12, an ink layer 13 and a connecting layer 14 which are bonded in sequence. The ink layer 13 is arranged around the inner edge of the reflective polarizing film 12 to shield the circuits and wirings leaking out of the display assembly 2. The reflective polarizing film 12 is arranged between the cover 11 and the ink layer 13. Since the reflective polarizing film 12 can reflect light, the cover 11 will have a certain reflection intensity after being bonded with the reflective polarizing film 12, and the light emitted by the ink layer 13 will also be reflected, thereby visually weakening the existence of the ink layer 13. As the reflectivity of the reflective polarizing film 12 is adjusted, the existence of the black edge can be visually invisible. In this embodiment, the reflective polarizing film 12 is RPM film, because the reflectivity of RPM film to light is greater than 45%, and the transmittance is greater than 90%, which is higher than other types of reflective polarizing films 12, and the visual weakening effect of black edges is more obvious. At the same time, the reflective polarizing film 12 is sandwiched between the cover plate 11 and the ink layer 13 to avoid direct contact between the reflective polarizing film 12 and the external environment, which can prevent it from being oxidized by air.

[0030] The display assembly 2 includes a display screen 21 and a backlight module 22. The display screen 21 is connected to the connection layer 14 and is used to display information, namely, to display the road conditions around the car. The backlight module 22 is located behind the display screen 21 and is used to provide backlight for the display screen 21 to ensure the display of the displayed information. Regarding the backlight module 22, it is a conventional technical means in the display field and does not fall within the key protection scope of the present utility model.

[0031] The cover plate 11 may be made of a transparent glass plate to improve the clarity of the rearview mirror and provide a good display effect. The thickness of the cover plate 11 may be selected between 1.0 mm and 2.0 mm, preferably 1.8 mm. Of course, depending on the different equipment on which the cover plate 11 is mounted, the thickness may be selected according to the type of equipment, and no specific restrictions are made here. The cover plate 11 may also be made of organic resin glass to ensure clarity and extend the service life of the cover plate 11.

[0032] Among them, the reflective polarizing film 12 is connected to the cover plate 11 in a full-fitting manner. Compared with the existing electroplating method, the full-fitting process is simpler, the degree of fit between the two is higher, and the cover plate assembly 1 can have better aesthetics. The thickness of the reflective polarizing film 12 is preferably between 0.073mm-0.080mm to ensure the overall thickness of the rearview mirror, and at the same time, the production cost of the reflective polarizing film 12 can be reduced. At the same time, in this embodiment, the reflective polarizing film 12 is preferably made of non-conductive material, so that it will not interfere with the circuit signal transmission in the display component 2, and the signal is more stable during the operation of the rearview mirror. Regarding the non-conductive material, metal oxides including titanium dioxide, chlorine trioxide and niobium pentoxide can be selected, which can not only ensure the use quality of the reflective polarizing film 12, but also meet the reflective polarizing film 12 The state is non-conductive.

[0033] Preferably, the backlight module 22 includes a light source, a light guide plate, an optical film and a plastic frame. The light source is preferably placed around the display screen 21, so that the overall thickness of the rearview mirror can be thinner and more ornamental.

[0034] Preferably, the cover plate assembly 1 and the display assembly 2 are also bonded by a full bonding process. Specifically, the display screen 21 is bonded to the back of the ink layer 13 by a full bonding method. The full bonding process is to assemble the cover plate assembly 1 and the display assembly 2 together by a colloid bonding method. Therefore, the connection layer 14 in the cover plate assembly 1 is a colloid layer. At the same time, in order to further ensure the display effect of the rearview mirror, optical glue is selected in this embodiment. Preferably, the optical glue is a silicone with UV resistance, and its refractive index is similar to that of the cover plate 11. While ensuring that the cover plate assembly 1 and the display assembly 2 have a good bonding effect, it can further ensure the service life of the rearview mirror.

[0035] Preferably, the width of the ink layer 13 is between 3mm and 8mm, which can ensure the display area of ​​the rearview mirror while shielding the circuits and wiring, and ensure that the function of the rearview mirror is not affected. Exemplarily, the width of the upper and lower sides of the ink layer 13 can be set to 3mm-5mm, and the width of the left and right sides can be set to 5mm-8mm, and no specific restrictions are made here. Among them, the ink layer 13 can be printed on the back of the reflective polarizing film 12 by means of a silk screen printing process. Specifically, the ink layer 13 can use black ink, apply black ink on the silk screen printing plate, print the silk screen printing plate on the reflective polarizing film 12, and then bake it to solidify the black ink on the reflective polarizing film 12. After the above steps, the ink layer 13 is formed. Of course, other processes can also be used for the production of the ink layer 13, and there is no restriction here.

[0036] In this embodiment, the rearview mirror also includes a photosensitive member, which is used to adjust the brightness of the rearview mirror, so as to realize adaptive adjustment of the brightness of the rearview mirror according to the lighting conditions, and ensure that the owner can clearly observe the road conditions. For example, when the light intensity is high, the brightness of the rearview mirror becomes low, and when the light intensity is low, the rearview will become brighter. Regarding the connection of the photosensitive member, the photosensitive member can be connected in series in the power supply circuit of the backlight module 22, wherein the resistance of the photosensitive member can change with the light intensity. For example, the photosensitive member can be selected as an optical coupler that increases with the increase of the light intensity, so that when the light intensity increases, the resistance value of the optical coupler increases, the voltage of the backlight module 22 decreases, the luminous brightness of the backlight module 22 decreases, and the brightness of the rearview mirror decreases. On the contrary, when the light intensity decreases, that is, when the sky becomes dark, the resistance value of the optical coupler decreases, the voltage of the backlight module 22 increases, the luminous brightness of the backlight module 22 increases, and the brightness of the rearview mirror increases. Of course, other photosensitive electronic components may be selected as the photosensitive element, and as long as the light brightness of the backlight module 22 can be adjusted, the specific components are not limited.

[0037] In this embodiment, the rearview mirror also includes a touch sensing module (not shown in the figure), wherein the touch sensing module is assembled between the cover plate assembly 1 and the display assembly 2, specifically between the connecting layer 14 and the display screen 21. The addition of the touch sensing module enables the rearview mirror to be operated by touch screen, thereby improving the convenience and experience of the car owner. The application of the touch sensing module in the field of electronic equipment belongs to conventional technical means and does not belong to the key protection scope of the present utility model. In order to ensure the quality and thickness of the rearview mirror, the touch sensing module can be integrated with the cover plate assembly 1. Specifically, the reflective polarizing film 12 is firstly bonded to the back of the cover plate 11 so that the two are fully bonded. Secondly, the ink layer 13 is screen-printed on the side of the reflective polarizing film 12 that is not bonded to the cover plate 11. The touch sensing module uses a finished module, and then the optical glue is bonded to the back of the ink layer 13. Finally, the touch sensing module is bonded to the back of the optical glue in a fully bonded manner.

[0038] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
