Electronic rearview mirrors capture images behind the vehicle through cameras and transmit the images to the display screen of the electronic rearview mirror for the driver to observe.

[0003] However, the traditional electronic rearview mirror can only display images, but cannot reflect the driving conditions behind the vehicle.

[0021] Figure 2 It is a schematic diagram of the stacking structure of the rearview mirror cover structure in another embodiment of the utility model;

[0022] Figure 3 It is a structural schematic diagram of the white ink layer of the rearview mirror cover structure in one embodiment of the utility model. DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0024] See also Figure 1 , Figure 2 and Figure 3As shown, a rearview mirror cover structure 10 includes: a cover body 100, a semi-transparent and semi-reflective film layer 200 and a white ink layer 300, the cover body 100 has a first side surface and a second side surface; the semi-transparent and semi-reflective film layer 200 is entirely disposed on the first side surface or the second side surface; the white ink layer 300 is disposed on the second side surface, the white ink layer 300 is provided with a reflective area 310 and a transmissive area 320, and a plurality of first transmission holes 321 are formed on the transmissive area 320.

[0025] It should be noted that by providing a semi-transmissive and semi-reflective film layer 200 on the first side or the second side of the cover body 100, the cover body 100 can achieve a semi-transmissive and semi-reflective effect. At the same time, a layer of white ink is silk-screened to further increase the reflectivity of the cover body 100, so as to further improve the clarity of the reflected image in the reflection area. In this way, the rearview mirror can simultaneously realize the reflection effect and the transmission display image effect.

[0026] It should also be noted that the white ink layer 300 is also provided on the transmission area 320. The reason is that if the white ink layer is not provided on the transmission area 320 at the same time, then when the display screen of the rearview mirror is in the off-screen state, the transmission area 320 will be black as a whole, reducing the reflection effect. At this time, the reflection effect of the transmission area 320 in the off-screen state is very poor, and the appearance of the transmission area 320 forms a sharp contrast with the appearance of the reflection area 310, which affects the uniformity and aesthetics of the appearance of the rearview mirror. Therefore, a white ink layer is also provided on the transmission area 320. Ink layer 300, so that when the display screen is off, the transmission area 320 can also achieve a better reflection effect; specifically, a plurality of first transmission holes 321 are formed on the transmission area 320 to ensure the transmission display image, and the first transmission holes 321 can be formed by an exposure process, and because the first transmission holes 321 are at the micrometer level, they cannot be perceived by the human eye; in order to ensure the uniformity of light passing through the transmission area 320, the first transmission holes 321 are distributed in a rectangular array, and the spacing distance between the first transmission holes 321 is the same.

[0027] Preferably, the first through hole 321 is a circular structure. In this embodiment, the diameter of the first through hole 321 is 10-20 μm. Preferably, the diameter of the first through hole 321 is 15 μm. At the same time, it should be noted that the spacing distance between each two first through holes 321 is preferably 15 μm, and the spacing distance between each two first through holes 321 can be matched to increase or decrease according to the required light transmittance.

[0028] In one embodiment, in order to prevent the white ink layer 300 from being transparent and further increase the reflectivity, the rearview mirror cover structure 10 further includes a black ink layer 400, which covers the side surface of the white ink layer 300 away from the cover body 100, and the black ink layer 400 is also provided with a reflection area and a transmission area, that is, the structure of the black ink layer 400 is the same as that of the white ink layer, and a plurality of second transmission holes are formed on the transmission area of ​​the black ink layer 400, and the center of the first transmission hole 321 is aligned with the center of the second transmission hole. Further, in order to avoid the deviation of the silk screen printing, which causes the offset black ink layer 400 to cover the first transmission hole 321 and affect the transmission effect, in this embodiment, the edge of the second transmission hole is expanded by 1-2 μm relative to the edge of the first transmission hole 32, that is, the diameter of the second transmission hole is larger than the diameter of the first transmission hole 321.

[0029] Preferably, the thickness of the semi-transmissive and semi-reflective membrane layer 200 is 0.3 μm.

[0030] Preferably, the thickness of the white ink layer 300 is 6-8 μm. For example, the thickness of the white ink layer 300 is 7 μm.

[0031] Preferably, the thickness of the black ink layer 400 is 6-8 μm. For example, the thickness of the black ink layer 400 is 7 μm.

[0032] Preferably, the rearview mirror cover structure 10 also includes a silicon dioxide protective layer 500, and the silicon dioxide protective layer 500 is covered on the black ink layer 400. When the black ink layer 400 is not used, the silicon dioxide protective layer 500 is covered on the white ink layer 300. Specifically, the silicon dioxide protective layer 500 is a composite film formed by alternating stacking of silicon nitride and silicon dioxide, which has high density and high hardness, so it can ensure that each ink layer is not scratched by foreign objects. In addition, when the semi-transparent and semi-reflective film 200 is arranged on the first side of the cover body 100, a layer of silicon dioxide protective layer 500 can also be covered on the semi-transparent and semi-reflective film 200 to prevent the semi-transparent and semi-reflective film 200 from being scratched by foreign objects.

[0033] For further information, see Figure 1As shown, in one embodiment, when the semi-transparent and semi-reflective film 200 is disposed on the first side of the cover body 100, the stacking order of the rearview mirror cover structure is: semi-transparent and semi-reflective film 200, cover body 100, white ink layer 300, black ink layer 400 and silicon dioxide protective layer 500. The semi-transparent and semi-reflective film 200 adopts a semi-transparent and semi-reflective AR (Anti-reflection) film, and the semi-transparent and semi-reflective AR film is plated on the first side of the cover body 100 by coating. The coating method can reduce the use of adhesive; then the white ink layer 300 and the black ink layer 400 are respectively screen-printed on the second side, and then the first through hole and the second through hole are formed by an exposure process; finally, a layer of silicon dioxide protective layer 500 is plated.

[0034] For further information, see Figure 2 As shown, in one embodiment, when the semi-transparent and semi-reflective film 200 is disposed on the second side of the cover body 100, the stacking order of the rearview mirror cover structure is: the cover body 100, the semi-transparent and semi-reflective film 200, the white ink layer 300, the black ink layer 400 and the silica protective layer 500.

[0035] A rearview mirror comprises the above-mentioned rearview mirror cover plate structure and also comprises a display screen.
