Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, and specifically provides a color-changing device, a rearview mirror and a vehicle. Background Art

[0002] The vehicle's rearview mirror with color-changing function can automatically darken when strong light is detected from behind, thereby reducing the intensity of light entering the driver's eyes and achieving an anti-glare effect. This design can effectively prevent the driver's vision from being affected by the headlights or other strong light sources of the rear vehicle during driving, ensuring driving safety at night or in bad weather conditions.

[0003] However, rearview mirrors with color-changing functions usually use electrochromic technology, which requires that when using electrochromic EC gel color or LC liquid crystal material color change, good sealing must be ensured to prevent rainwater or sewage or other liquids from entering the lens of the rearview mirror during car washing and damaging the electrochromic layer of the lens. In the prior art, the color-changing device generally includes two substrates and an electrochromic layer arranged between the two substrates, and a conductive copper foil is connected to the electrochromic layer. When the conductive copper foil is energized, the electrochromic layer changes color. In the prior art, the angle of the color-changing device in the rearview mirror is usually adjustable to meet the needs of different drivers, so that different drivers can adjust the rear view range that the rearview mirror can see according to their own needs, which requires a gap to be formed between the rearview mirror housing and the color-changing device (such as Figure 6 For the rearview mirror water inlet clearance C) shown in Figure 6 The rearview mirror water inlet clearance C is only used to describe the problems existing in the prior art and does not indicate that Figure 6 The structures shown are all prior arts. The rearview mirror gap C makes the color-changing device easy to adjust, but it will cause the problem of easy water ingress. The method of directly connecting the conductive copper foil to the color-changing layer, after water enters the water inlet gap C of the rearview mirror, it is easy for water to enter the gap between the conductive copper foil and the substrate and finally enter the color-changing layer to damage the color-changing layer.

[0042] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0043] It should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0044] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0045] In order to solve the problems mentioned in the background technology, that in the prior art there is a rearview mirror water inlet gap C between the vehicle rearview mirror housing 10 and the photochromic device, water easily enters the rearview mirror water inlet gap C, and the photochromic device has poor sealing performance, which allows water to enter the interior of the photochromic device and damage the photochromic device, the utility model provides a new photochromic device to solve the above problems.

[0046] See also Figures 1 to 3 The color-changing device of the utility model includes a first substrate 1 and a second substrate 2 which are stacked; a color-changing layer 3, the color-changing layer 3 is located between the first substrate 1 and the second substrate 2; a first conductive sealing layer 4, the first conductive sealing layer 4 is located between the first substrate 1 and the color-changing layer 3, and the first conductive sealing layer 4 is sealed and connected to the first substrate 1; a first conductive component 5, the first end 52 of the first conductive component 5 is electrically connected to the color-changing layer 3 through the first conductive sealing layer 4, and the first end 52 of the first conductive component 5 and the color-changing layer 3 are both located on the side of the first conductive sealing layer 4 away from the first substrate 1; a first sealant 6, the first sealant 6 surrounds the circumference of the color-changing layer 3 and is filled between the first substrate 1 and the second substrate 2, and is filled into the gap between the first conductive component 5 and the color-changing layer 3, so as to block the direct contact between the first conductive component 5 and the color-changing layer 3.

[0047] Specifically, if Figure 3As shown, the color-changing layer 3 is located below the first substrate 1 and above the second substrate 2. The cross-sectional areas of the first substrate 1 and the second substrate 2 in the horizontal direction are larger than the cross-sectional area of ​​the color-changing layer 3. In order to cover the color-changing layer 3, a gap is formed below the first substrate 1 and above the second substrate 2 around the color-changing layer 3. The gap needs to be sealed. If the first conductive component 5 is directly connected to the color-changing layer 3, and then the gap on the lower surface of the first conductive component 5 is filled with sealant, although the sealant can seal the gap on the lower surface of the first conductive component 5, it can prevent water or other liquids from entering the first conductive component 5. However, water may enter the color-changing layer 3 from between the upper surface of the first conductive component 5 and the first substrate 1, and the first conductive sealing layer 4 is provided in the utility model, and the first end 52 of the first conductive component 5 is connected to the bottom of the first conductive sealing layer 4, and the first conductive sealing layer 4 is located above the color-changing layer 3 and below the first substrate 1, that is, the first end 52 of the first conductive component 5 and the color-changing layer 3 are located on the lower side of the first conductive sealing layer 4, and the left and right lateral gaps between the first conductive component 5 and the color-changing layer 3 are the first gaps A, and the first gaps A are located below the first conductive sealing layer 4. Figure 1 and 3 As shown, the first sealant 6 is filled to the first gap A to block the direct contact between the first conductive component 5 and the color-changing layer 3. When water flows into the upper surface of the first conductive component 5 and then flows to the left, it will be blocked by the first sealant 6; and the first conductive sealing layer 4 and the first substrate 1 are electroplated and connected, and water will not enter the color-changing layer 3 from between the first conductive sealing layer 4 and the first substrate 1.

[0048] To summarize, the first conductive sealing layer 4 is used to seal the gap between the first conductive component 5 and the first substrate 1, and the first sealant 6 is used to block the lateral gap between the first conductive component 5 and the color-changing layer 3 to prevent water from entering the color-changing layer 3 through the first conductive component 5. The first conductive sealing layer 4 and the first sealant 6 work together to block water, improve the sealing performance, and prevent the color-changing layer 3 from being damaged by the infiltrated water.

[0049] Continue reading Figure 1 and 3 ,like Figure 1 and 3 As shown, the color-changing device also includes a second conductive sealing layer 7, which is located between the color-changing layer 3 and the second substrate 2 and is sealed to the second substrate 2. The first end 82 of the second conductive component 8 is electrically connected to the color-changing layer 3 through the second conductive sealing layer 7. The first end 82 of the second conductive component 8 and the color-changing layer 3 are both located on the side of the first conductive sealing layer 7 away from the second substrate 2. The first sealant 6 is filled into the gap between the second conductive component 8 and the color-changing layer 3 to prevent the second conductive component 8 and the color-changing layer 3 from directly contacting each other.

[0050] Specifically, the second conductive sealing layer 7 is located below the color-changing layer 3 and above the second substrate 2, and the first end 82 of the second conductive component 8 is connected to the top of the second conductive sealing layer 7. That is to say, the first end 82 of the second conductive component 8 and the color-changing layer 3 are both located above the second conductive sealing layer 7. The second conductive sealing layer 7 is electroplated and connected to the second substrate 2, and has good sealing properties, so that water will not enter the color-changing layer 3 from the gap between the second conductive component 8 and the second substrate 2. The first sealant 6 is also filled into the second gap B between the second conductive component 8 and the color-changing layer 3, blocking the cross-sectional gap between the second conductive component 8 and the color-changing layer 3 to prevent water from entering.

[0051] Continue reading Figure 1 The color-changing layer 3 includes a first conductive film 31 and a second conductive film 32 which are stacked, a liquid crystal layer 33 is arranged between the first conductive film 31 and the second conductive film 32, a first conductive sealing layer 4 is connected to the first conductive film 31, and a second conductive sealing layer 7 is connected to the second conductive film 32. Based on this, when the first conductive member 5 and the second conductive member 8 are powered on, the liquid crystal layer 33 will change color to prevent glare.

[0052] Although, in the preferred embodiment, the color-changing layer is a liquid crystal LC color-changing material for example, and the liquid crystal changes color when electricity is turned on to achieve an anti-glare effect, this is not restrictive. The color-changing layer can also be made of EC gel material, and the EC gel material changes color when electricity is turned on. EC gel usually refers to ethyl cellulose (EC) gel, and technical personnel in this field can set it according to actual conditions.

[0053] In addition, although in the present preferred embodiment, the first conductive component 5 is connected to the first conductive film 31 through the first conductive sealing layer 4, and the second conductive component 8 is connected to the second conductive film 32 through the second conductive sealing layer 7, this is not restrictive; in other embodiments, the second conductive component 8 and the second conductive sealing layer 7 are not provided, and two first conductive components 5 are included, and the two first conductive components 5 are provided as described above, but are located at different positions, for example, respectively located on opposite left and right sides, and the first conductive sealing layer 4 is divided into two parts, the two parts are not connected to each other, and are both sealed and connected to the first substrate 1, one first conductive component 5 directly transmits electricity to the first conductive film 31 through a part of the first conductive sealing layer 4, and a conductive part (not shown in the figure) is provided under the other part of the first conductive sealing layer 4, and the conductive part is connected to the second conductive film 32, and the other first conductive component 5 transmits electricity to the second conductive film 32 through the first conductive sealing layer 4 and the conductive part, and the liquid crystal layer 33 can still be discolored, and the conductive part is located within the sealing range of the first sealant 6, that is, the inner side of the first sealant 6.

[0054] In this preferred embodiment, the first conductive sealing layer 4 and the first substrate 1 are connected by electroplating to achieve sealing, and the second conductive sealing layer 4 and the second substrate 2 are connected by electroplating to achieve sealing, but this is not restrictive, and other sealing methods can also be used, such as sealing by sealant connection, laser welding, etc., and technical personnel in this field can set it according to actual conditions.

[0055] Further, see Figure 1 and 3 A second sealant 34 is provided in the gap between the liquid crystal layer 33 and the first conductive film 31 and the second conductive film 32. The second sealant 34 surrounds the liquid crystal layer 33 and is sealed upward to the lower surface of the first conductive film 31 and downward to the upper surface of the second conductive film 32. The second sealant 34 can further prevent water from entering the liquid crystal layer 33 and damaging the liquid crystal layer 33.

[0056] In this preferred embodiment, the first conductive film 31 and the second conductive film 32 are both ITO (Indium Tin Oxide, indium oxide doped with tin) conductive films. Of course, this is not restrictive. It can also be FTO (Fluorine-doped Tin Oxide, fluorine-doped tin dioxide) conductive film, or it can be a layer film structure made of other conductive materials for specific transmission and conductive functions. Those skilled in the art can set it according to actual conditions.

[0057] Continue reading Figure 1 ,like Figure 1 As shown, the first end 52 of the first conductive member 5 is connected to the first conductive sealing layer 4, the first end 82 of the second conductive member 8 is connected to the second conductive sealing layer 7, and the second end 53 of the first conductive member 5 and the second end 83 of the second conductive member 8 are both connected to the side of the second substrate 2 away from the first substrate 1. Specifically, the upper end of the first conductive component 5 is connected to the lower surface of the first conductive sealing layer 4, and the first conductive component 5 is bent downward so that the lower end of the first conductive component 5 is bonded and connected to the lower surface of the second substrate 2, and the first conductive component 5 is hidden in the first substrate 1 and is completely shielded by the first substrate 1. The upper end of the second conductive component 8 is connected to the upper surface of the second conductive sealing layer 7, and the second conductive component 8 is bent downward. The lower end of the second conductive component 8 is bonded and connected to the lower surface of the second substrate 2, and the second conductive component 8 is hidden in the first substrate 1 and is completely shielded by the first substrate 1. The first conductive component 5 and the second conductive component 8 are completely hidden in the first substrate 1, and the lower ends are both bonded to the lower surface of the second substrate 2, which can not only improve the aesthetics, but also facilitate the connection of the circuits or conductive parts in the vehicle with the first conductive component 5 and the second conductive component 8 in the rearview mirror housing 10 when the color-changing device is assembled to the rearview mirror.

[0058] Preferably, the first conductive sealing layer 4 is configured to be able to shield the first sealant 6, the second sealant 34, the first conductive component 5 and the second conductive component 8. Specifically, the first conductive sealing layer 4 is a conductive metal ring, the outer circumference of the annular structure is the same as the outer circumference of the first substrate 1, and the inner circumference of the annular structure is located within the outer circumference of the color-changing layer 3 and within the inner circumference of the second sealant 34, so as to completely cover the first sealant 6, the second sealant 34, the first conductive component 5 and the second conductive component 8, so that the first sealant 6, the second sealant 34, the first conductive component 5 and the second conductive component 8 cannot be seen from top to bottom, thereby improving the aesthetics.

[0059] In other embodiments, the first conductive sealing layer 4 is configured to only shield the first sealant 6 and the second sealant 34 .

[0060] In other embodiments, the first conductive sealing layer 4 is configured to shield the first sealant 6 .

[0061] In addition, the color-changing device further includes a transparent conductive layer 9, which is connected to and arranged in the same layer as the first conductive sealing layer 4, and the transparent conductive layer 9 and the first conductive sealing layer 4 are arranged to cover the entire area of ​​the color-changing layer 3 together. Specifically, the entire inner region of the ring of the first conductive sealing layer 4 is the transparent conductive layer 9, and the first conductive sealing layer 4 is connected to and covers a portion of the upper surface of the color-changing layer 3. The area not covered by the first conductive sealing layer 4 is covered by the transparent conductive layer 9 to the top of the color-changing layer 3. The arrangement of the transparent conductive layer 9, due to its transparent conductive property, does not affect the effect of preventing glare from the color-changing layer 3, and can also play a role in transmitting electricity well to the first conductive film 31 of the color-changing layer 3.

[0062] The first conductive sealing layer 4 can be a chrome ring, a copper ring, an aluminum ring, or can be made of other conductive materials. The first conductive sealing layer 4 can be a ring structure or a layered structure that completely covers the color-changing layer 3. For example, the entire transparent conductive layer 9 is connected to the lower surface of the first substrate 1 by electroplating. Technical personnel in this field can set it according to actual conditions.

[0063] The transparent conductive layer 9 is preferably a transparent and conductive layer structure made of chromium. Of course, it can also be a transparent and conductive layer structure made of other materials, and those skilled in the art can set it according to actual conditions.

[0064] The second conductive sealing layer 7 is a reflective conductive layer, which completely covers the color-changing layer 3 from the bottom of the color-changing layer 3. The reflective conductive layer can be made of metal grid, nano silver wire, graphene and other materials. Of course, this is not a limitation. The second conductive sealing layer 7 can be a conductive metal ring. The outer ring line of the metal ring is located outside the outer circumference of the color-changing layer 3, and the inner ring line of the metal ring is located within the outer circumference of the color-changing layer 3. A reflective conductive layer is arranged inside the ring, and the reflective conductive layer is connected to the metal ring. The reflective conductive layer is connected to the lower surface of the color-changing layer 3, which can still play a reflective and good conductivity.

[0065] like Figure 1 As shown, in this preferred embodiment, the outer circumference of the first conductive sealing layer 4 is located outside the outer circumference of the color-changing layer 3, and the outer circumference of the second conductive sealing layer 7 is also located outside the outer circumference of the color-changing layer 3. The first sealant 6 is filled below the first conductive sealing layer 4 and above the second conductive sealing layer 7 outside the outer circumference of the color-changing layer 3.

[0066] In another embodiment, the first conductive sealing layer 4 is not a ring-shaped structure but a short strip structure, which only plays the role of sealing and transmitting electricity. The first sealant 6 is sealed upward to the bottom of the first conductive sealing layer 4, and also seals to the area outside the outer periphery of the color-changing layer 3 where the first conductive sealing layer 4 is not set on the lower surface of the first substrate 1.

[0067] In another embodiment, the second conductive sealing layer 7 is also a short strip structure, which only plays the role of sealing and transmitting electricity. The first sealant 6 seals downward to the top of the second conductive sealing layer, and also seals to the area outside the outer periphery of the color-changing layer 3 where the second conductive sealing layer 7 is not set on the upper surface of the second substrate 2.

[0068] In addition, the first sealant 6 is located within the outer periphery of the first substrate 1 and covers the side of the second substrate 2. Figure 1 As shown, the outer periphery of the first sealant 6 does not exceed the outer periphery of the first substrate 1, and is filled downward to the outer side surface of the second substrate 2, covering the outer side surface of the second substrate 2 and the second conductive member 8. The first sealant 6 adopts ultraviolet curing glue, and the ultraviolet lamp is arranged obliquely below the outer periphery of the first sealant 6. Based on the above arrangement, the area of ​​the glue that can be irradiated by the ultraviolet lamp is increased, the ultraviolet curing rate in the process is accelerated, the curing time is shortened, and the probability of poor glue sealing due to insufficient ultraviolet curing is reduced.

[0069] Furthermore, the material of the first substrate 1 is transparent glass, and the second substrate 2 can be transparent glass or non-transparent glass. After the color-changing device is installed on the rearview mirror, the first substrate 1 is located on the outside and the second substrate 2 is located on the inside. Based on this, it can be seen that the second conductive component 8 is closer to the inside than the first conductive component 5, so it is less likely for water to enter the second conductive component 8. Therefore, the second conductive sealing layer 7 may not be provided, and the second conductive component 8 is directly contacted and connected with the color-changing layer 3. Of course, it is preferred to provide a second conductive sealing layer 7 and fill the first sealant into the gap between the second conductive component 8 and the color-changing layer 3. Those skilled in the art can set it according to actual conditions.

[0070] Furthermore, in the left and right horizontal directions, the cross-sectional area of ​​the first substrate 1 is larger than the cross-sectional area of ​​the second substrate 2. Since the first substrate 1 is located on the outside and the second substrate 2 is located on the inside, reducing the second substrate 2 can effectively reduce costs and is more suitable for installing the color-changing device on the rearview mirror. Of course, this is not restrictive, and the cross-sectional areas of the first substrate 1 and the second substrate 2 can also be the same.

[0071] See next Figure 4 ,like Figure 4 As shown, the lateral distance of the gap between the first conductive component 5 and the color-changing layer 3 is greater than the first preset value; specifically, the gap between the first conductive component 5 and the first conductive film 31 of the color-changing layer 3 is the first gap A, and the lateral distance of the first gap A is a1, which is greater than 1 mm.

[0072] Furthermore, the first conductive member 5 is connected to the lower surface of the first conductive sealing layer 4 through the first conductive adhesive 51 .

[0073] Next, see Figure 5 ,like Figure 5 As shown, the lateral distance of the gap between the second conductive member 8 and the color-changing layer 3 is greater than the second preset value. Specifically, the gap between the second conductive member 8 and the second conductive film 32 of the color-changing layer 3 is a second gap B, and the lateral distance of the second gap B is b1, which is greater than 1 mm.

[0074] Furthermore, the second conductive member 8 is connected to the upper surface of the second conductive sealing layer 7 through the second conductive adhesive 81 .

[0075] It should be noted that the present invention does not impose any restrictions on the specific values ​​of the first preset value and the second preset value. The two may be the same or different, and may be 1mm, 1.1mm, 1.2mm, or other values. Those skilled in the art may set them according to actual conditions.

[0076] The first conductive component 5 and the second conductive component 8 of the present invention are preferably conductive copper foil. Of course, this is not restrictive. They can also be conductive aluminum foil, other types of conductive metal foil, or conductive materials. Those skilled in the art can set them according to actual conditions.

[0077] In a second aspect, the utility model further provides a rearview mirror, the rearview mirror comprising any one of the color-changing devices in the above embodiments. The rearview mirror can be an exterior rearview mirror located outside the vehicle, or an interior rearview mirror located inside the vehicle's cab.

[0078] Specific reference Figure 6 ,like Figure 6 As shown, the rearview mirror of the utility model has a rearview mirror gap C formed between the housing 10 of the rearview mirror and the color-changing device described in the above embodiment. After water enters the rearview mirror gap C, since the color-changing device described in the above embodiment is used, the water will be blocked outside and will not enter the color-changing layer 3, thereby preventing the color-changing layer 3, the core component of the color-changing device, from being damaged.

[0079] In a third aspect, the utility model further provides a vehicle, the vehicle comprising any one of the rearview mirrors in the above embodiments. The vehicle may be an electric vehicle, a fuel vehicle, a hybrid vehicle, a plug-in hybrid vehicle, a small passenger car, a large passenger car or a truck, and a person skilled in the art may set the type of vehicle according to actual conditions.

[0080] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
