Description

Light and thin electronic anti-dazzle lens and vehicle rearview mirror
Technical Field
The invention relates to the technical field of vehicle accessories, in particular to a light and thin electronic anti-dazzle lens and a vehicle rearview mirror with the light and thin electronic anti-dazzle lens.
Background
In response to the market demand increase and technical innovation, more and more types of products need to use an electronic anti-dazzle function, such as an inside rearview mirror, an outside rearview mirror and the like. Meanwhile, in order to improve the impression, the interior rearview mirror is gradually developed and used for providing the impression experience of a clearer and larger scene for a vehicle owner through an electronic display screen image. This requires that the interior mirror should integrate a physical reflection function, an electronic anti-glare function, and a display screen function. Therefore, the interior mirror needs to be equipped with an electronic antiglare lens.
The conventional electronic anti-glare lens generally includes at least a first substrate, an electrochromic material layer, a reflective layer, and a second substrate. The electrochromic material layer usually comprises an upper conducting layer and a lower conducting layer, the electrochromic material layer is made of liquid electrochromic materials, semi-liquid materials or gel-state small molecular materials, a glue filling opening is formed in the side face of the electrochromic material layer to fill the electrochromic materials, after the electrochromic materials are filled, the electrochromic material layer needs to be sealed through a special glue sealing process to avoid material leakage, and the production process is complex. Meanwhile, there are special requirements for the materials of the upper and lower conductive layers, and the thicknesses of the first substrate and the second substrate are also required to be made thicker (usually not less than 0.8mm) to ensure the structural reliability of the electronic anti-glare lens, so the overall thickness of the conventional electronic anti-glare lens is usually thicker.
In addition, the reflecting layer is only used for realizing a physical reflecting function, and the reflectivity of the whole electronic anti-dazzle lens is changed by changing the transmittance of the electrochromic material layer through electrification, so that the anti-dazzle purpose is achieved. Although the traditional electronic anti-dazzle lens realizes the automatic anti-dazzle function, the total of the reflectivity of the electronic anti-dazzle lens to surface layer light and the transmittance to the display screen light is always less than 100 percent due to the loss of the composition structure of the electronic anti-dazzle lens to the display screen light. For the vehicle-mounted rearview mirror, the reflectivity of the vehicle-mounted rearview mirror is required to be not lower than 40% by regulation, and the transmittance of the vehicle-mounted rearview mirror to the light of the display screen is usually not higher than 50% due to the loss of the composition structure of the traditional electronic anti-dazzle lens to the light of the display screen, so that the final display brightness of the light of the display screen after passing through the electronic anti-dazzle lens is not half of the surface brightness of the display screen. If the requirement of the appearance is met, the brightness of the display screen is required to be extremely high, and the extremely high brightness means that the light source of the display screen has higher heat accumulation, so that the requirement on the heat dissipation of the rearview mirror in the automobile is higher.

Detailed Description
The following detailed description is given with reference to the accompanying drawings for illustrating the contents, structural features, and objects and effects of the present invention.
In the description of the present invention, it should be understood that the terms "upper", "lower", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, and thus, should not be construed as limiting the scope of the present invention.
The invention discloses a vehicle rearview mirror which is arranged on a vehicle body and used for displaying the surrounding environment of the vehicle body so as to improve the comfort and safety of driving. The vehicle rearview mirror comprises a light and thin electronic anti-dazzle lens 100 and a display screen 200, wherein the light and thin electronic anti-dazzle lens 100 is arranged on the light emergent side of the display screen 200. The light and thin electronic anti-dazzle lens 100 comprises a first substrate 1, a second substrate 2, an electrochromic material layer 3 and a reflecting layer 4, wherein the first substrate 1, the second substrate 2, the electrochromic material layer 3 and the reflecting layer 4 are arranged in a stacked mode, a sealing structure 5 is arranged on the periphery of the electrochromic material layer 3, and the upper end and the lower end of the sealing structure 5 are fixed with the first substrate 1 and the second substrate 2 respectively. In use, the first substrate 1 faces a user, and the second substrate 2 is mounted on the light-emitting side of the display 200. The electrochromic material layer 3 is a solid material, and the electrochromic material layer 3 is arranged between the first substrate 1 and the second substrate 2. The reflective layer 4 is provided on the side of the layer of electrochromic material 3 facing away from the first substrate 1. The "second substrate 2 is mounted on the light-emitting side of the display 200" does not limit that the second substrate 2 is in direct contact with the display 200, and the second substrate 2 may be directly mounted on the display 200 or separated from the display 200 by another structure.
In one embodiment, the reflective layer 4 only has a reflective material, and optionally the reflective material has a reflectivity of not less than 30% for natural light, preferably the reflective material has a reflectivity of not less than 40% for natural light, and more preferably the reflective material has a reflectivity of not less than 50% for natural light. The material of the reflective layer 4 can be selected to be a conductive material or an insulating material, and when the conductive material is selected for the reflective layer, the reflective layer can simultaneously serve as a single-sided conductive layer (such as a lower conductive layer) of the electrochromic material layer.
The reflective layer may have a certain polarization characteristic in addition to the reflection characteristic, so that it may exhibit a corresponding transmittance and reflectance according to a polarization direction of incident light. Preferably, in one embodiment, the reflective layer 4 has both a reflective material and a polarizing material. That is, the reflective layer 4 has both reflection characteristics and transmission characteristics, and can selectively transmit or reflect light depending on the polarization direction of the light of the display panel. For the vehicle rearview mirror, the reflectivity of the reflective layer 4 to natural light should meet the requirement of the reflectivity of the vehicle rearview mirror by the law (common knowledge), the transmittance of the reflective layer 4 to the light of the display screen 200 may be different according to the polarization characteristics of the light of the display screen 200, and of course, the polarization direction of the reflective layer 4 is preferably consistent with the polarization direction of the light of the display screen 200, so that the light of the display screen 200 can be basically transmitted.
The working process of the present invention is explained below: when the display screen 200 is closed, the reflection of the surrounding environment is satisfied through the physical reflection characteristics of the reflection layer 4, so that the driver can watch the reflection, and the reflectivity of the whole light and thin electronic anti-glare lens 100 can be selected to be higher than 40%, higher than 50% or higher so as to enhance the reflection of the external natural light, so that the driver can clearly see the situation of the rear side of the vehicle body through the light and thin electronic anti-glare lens 100. When the reflectivity of the lens needs to be changed, the voltage of the conducting layer of the electrochromic material layer 3 is adjusted to enable the electrochromic material to change the transmittance of the electrochromic material, so that the reflectivity is adjusted, and the automatic anti-dazzle function is realized. When the display screen 200 is opened, the light emitted by the display screen 200 reaches the human eyes after passing through the thin and light electronic anti-glare lens 100, and at this time, the transmittance of the electrochromic material layer 3 is adjusted to be in a high transmittance state, so that the luminance transmittance of the display screen 200 reaches a high level state, and meanwhile, since the reflection layer 4 has polarization characteristics and allows the light of the display screen 200 to be substantially transmitted, the total of the reflectance of the thin and light electronic anti-glare lens 100 to the surface natural light and the transmittance (not less than 60%) of the light of the display screen 200 can finally reach 100%, even more than 100%. That is, the reflection performance as a mirror when the display panel 200 is closed and the high transmittance of the light to the display panel 200 when the display panel 200 is opened are both considered.
Hereinafter, the vehicle mirror according to the present invention will be described in further detail with reference to fig. 1 to 3.
In some embodiments, the reflective layer 4 is an insulating structure. Because the reflection layer 4 itself has a very high transmittance to the light of the display screen 200, it is not necessary to share the reflection layer (the material is usually silver) with the lower conductive layer of the electrochromic material layer in the conventional technology to save a layer of structure to reduce the loss to the light of the display screen, and therefore, the position of the reflection layer 4 can be flexibly set, and is not limited to be set between the electrochromic material layer 3 and the second substrate 2.
The thickness of the electrochromic material layer 3 is 0.1mm-2mm, the electrochromic material layer comprises an upper conducting layer and a lower conducting layer which are arranged in a stacked mode, the upper conducting layer and the lower conducting layer are sequentially arranged on the lower side of the first substrate 1, conducting contact positions used for being connected with external driving voltage are arranged on the upper conducting layer and the lower conducting layer, and the electrochromic material can show different transmittances by adjusting the electrifying condition of the upper conducting layer and the lower conducting layer. Incidentally, the electrochromic material layer may be a solid electrochromic material as in the prior art.
The thickness of the first and second substrates 1, 2 is 0.3mm-3.5mm, and the material of the second substrate 2 is optionally transparent glass, and comprises a first surface 21 facing the electrochromic material layer 3 and a second surface 22 located opposite to the first surface 21. Likewise, the material of the first substrate 1 may also be transparent glass, which includes a first surface 11 facing the user and a second surface 12 located at the opposite side of the first surface 11. An explosion-proof film (not shown) is attached to the first surface 11 of the first substrate 1 to protect the first substrate 1. Optionally, other additional structural protection members may be disposed above the first surface 11 of the first substrate 1 to protect the first substrate 1. Further, a silk-screen layer (not shown) is disposed on the periphery of the second surface 12 of the first substrate 1, and the silk-screen layer is used for shielding circuits, adhesives and the like inside the vehicle rearview mirror, so that the vehicle rearview mirror is more attractive as a whole. Wherein, the silk-screen layer can have a reflectivity of not less than 30%. In addition, the first substrate 1 may have a structure in which two thin glass layers are stacked, and at this time, a screen printing layer may be formed on a periphery of the outer thin glass layer. In this embodiment, the edge of the first substrate 1 is designed to be rounded, but it should not be limited thereto.
Fig. 1 shows a first embodiment of the invention, in which the reflective layer 4 is fixed to the second surface 22 of the second substrate 2, as shown in fig. 1. Alternatively, the reflective layer 4 and the second surface 22 of the second substrate 2 may be directly adhered together through an OCA adhesive cloth layer, and other structures may be disposed between the reflective layer 4 and the second surface 22 of the second substrate 2.
Fig. 2 shows a second embodiment of the present invention, as shown in fig. 2, different from the first embodiment, in this embodiment, the reflective layer 4 is fixed on the light-emitting surface of the display panel 200, at this time, the display panel 200 may not be provided with a polarizer, and polarized light is emitted by using the polarization characteristic of the reflective layer 4, so that the overall structure is simpler, and the cost can be saved. Optionally, the reflective layer 4 and the light-emitting surface of the display screen 200 may be directly adhered together through an OCA adhesive cloth layer, and other structures may also be arranged between the reflective layer 4 and the light-emitting surface of the display screen 200.
Fig. 3 shows a third embodiment of the present invention, and as shown in fig. 3, unlike the first and second embodiments, in this embodiment, a reflective layer 4 is provided between an electrochromic material layer 3 and a second substrate 2. The upper surface of the reflection layer 4 is fixed with the electrochromic material layer 3, optionally, the reflection layer 4 and the electrochromic material layer 3 can be directly adhered together through an OCA cloth-adhering layer, and other structures can be arranged between the reflection layer 4 and the electrochromic material layer 3. The lower surface of the reflective layer 4 is fixed to the second substrate 2, and similarly, the reflective layer 4 and the second substrate 2 may be directly bonded together by an OCA adhesive layer, and another spacer structure may be provided between the reflective layer 4 and the second substrate 2.
In summary, the electrochromic material layer 3 of the present invention is made of solid material, no additional glue filling opening is required to be arranged for material injection in the production process, the requirement of the glue sealing process is reduced, the production process is simplified, no special requirement is required for the material selection of the upper and lower conductive layers of the electrochromic material layer 3, the sealing structure 5 around the electrochromic material layer 3 can also be made of a sealing material commonly used in the market, the thicknesses of the first substrate 1 and the second substrate 2 can also be made thinner, and the overall thickness and weight of the electronic anti-glare lens 100 can be made smaller. In addition, the reflecting layer 4 has both a reflecting material and a polarizing material, and can selectively transmit or reflect light according to the polarization direction of the light of the display screen, so that more light of the display screen 200 can be allowed to transmit, the brightness utilization rate of the display screen 200 is greatly improved, and the requirement on the brightness of the display screen 200 is reduced while the appearance of a display picture is ensured. Therefore, the heat dissipation requirement of the display screen 200 is lower, which is beneficial to simplifying the structure of the whole vehicle rearview mirror, so that the whole thickness and weight of the whole vehicle rearview mirror can be further reduced, and the reliability of the whole vehicle rearview mirror can be improved.
