Abstract
Description
Technical Field
[0001] This disclosure relates to the field of anti-glare technology, and more particularly to an optical device, an anti-glare mirror reflector, and a vehicle. Background Technology
[0002] In related technologies, the optical components on the rearview mirrors of vehicles cannot effectively converge light, which can lead to errors or delays in the adjustment of the anti-glare function of the rearview mirrors, affecting their use. Utility Model Content
[0003] The purpose of this disclosure is to provide an optical device, an anti-glare mirror reflection device, and a vehicle to solve the problems in the aforementioned related technologies.
[0004] To achieve the above objectives, one aspect of this disclosure provides an optical device comprising:
[0005] A light guide component, wherein the light guide component is transparent, and the light guide component is provided with a light-inlet surface and a light-outlet surface, wherein the light-outlet surface is directed toward the photosensitive sensor;
[0006] The first protrusion mechanism is provided at least partially on the light-inlet surface and / or the light-outlet surface;
[0007] The first protrusion mechanism is configured as a mesh pattern protruding from the light-inlet surface or the light-outlet surface, so that the first protrusion mechanism can cause light to converge toward the photosensitive sensor.
[0008] The aforementioned technical solution utilizes a mesh pattern to refract light. This means that light entering the light guide from the light-inlet surface is refracted by the mesh pattern, directing it towards the photosensor. Similarly, light exiting the light guide from the light-outlet surface is refracted by the mesh pattern, also directing it towards the photosensor. This improves the photosensor's accuracy in detecting light. Furthermore, the mesh pattern expands the light acquisition range. Light from different angles or directions is refracted by the mesh pattern upon reaching the light-inlet or light-outlet surface, causing it to converge towards the photosensor. This allows the photosensor to detect more light, further enhancing its accuracy. Ultimately, this improves the accuracy of anti-glare adjustment in mirror-reflective devices such as rearview mirrors, ensuring optimal performance.
[0009] In some possible implementations, the first protrusion mechanism includes a plurality of first protrusions, which are spaced apart along the transverse and longitudinal directions, respectively.

[0020] In some possible implementations, the light guide is provided with an axis perpendicular to the light-inlet surface or the light-outlet surface, and the area of the first protrusion in the direction perpendicular to the axis gradually decreases in the direction away from the light guide.
[0021] This setup facilitates light convergence, allowing for the refraction of light from different angles or directions to achieve the desired convergence.
[0022] In some possible implementations, the end of the first protrusion facing away from the light guide is configured as a curved surface.
[0023] This setup facilitates the refraction of light, allowing for the refraction of light from different angles or directions, and enabling the convergence of light rays.
[0024] In some possible implementations, the light guide is provided with an axis perpendicular to the light-inlet surface or the light-outlet surface, and in the direction perpendicular to the axis, the area of the first protrusion mechanism is larger than the photosensitive area of the photosensitive sensor.
[0025] By setting it up in this way, light from different directions or angles can be refracted and illuminated onto the photosensor as much as possible.
[0026] In some possible implementations, the optical device further includes a second protrusion mechanism;
[0027] The first protrusion mechanism is provided at least a portion of one of the light-inlet surface and the light-outlet surface, and the second protrusion mechanism is provided at least a portion of the other surface;
[0028] The second protrusion mechanism is configured as a straight groove pattern along the lateral or longitudinal direction, and the second protrusion mechanism can cause the light to converge toward the photosensitive sensor.
[0029] This setup expands the range of directions and angles from which light can be captured, allowing for the acquisition of more light.
[0030] In some possible implementations, the second protrusion mechanism includes a plurality of second protrusions, the second protrusions being configured as strips;
[0031] Multiple second protrusions are spaced apart along the lateral or longitudinal direction.
[0032] In some possible implementations, the light guide is provided with an axis perpendicular to the light emitting surface or the light receiving surface, and the area of the cross section of the second protrusion gradually decreases in the direction perpendicular to the axis along a direction away from the light guide.
[0033] This design facilitates the formation of straight groove patterns.
[0034] In some possible implementations, the end of the second protrusion facing away from the light guide is configured as a pointed cone shape.
[0035] By setting it up in this way, light can be converged by refracting light from different angles or directions.
[0036] In some possible implementations, the light guide includes a plate and mounting feet, with two opposite sides of the plate respectively serving as the light-inlet surface and the light-outlet surface, and one end of the mounting feet connected to the plate.
[0037] This design facilitates the assembly and fixation of the light guide components.

[0074] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0075] In this disclosure, unless otherwise stated, directional terms such as first direction, second direction, lateral direction, and longitudinal direction, as shown in the figures, do not specifically refer to vertical or horizontal directions, and "inner" and "outer" refer to the inner and outer parts of the relevant components. Furthermore, the terms "first," "second," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance.
[0076] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can be a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.
[0077] Rearview mirrors are used by drivers to visually observe the situation behind or to the sides of the vehicle. At night, when there is strong light shining from behind, it will create a strong reflection on the rearview mirror, interfering with the driver's vision and affecting their ability to observe road conditions. For example, when a vehicle behind turns on its high beams, it will create a strong reflection on the rearview mirror.
[0078] In related technologies, the optics on vehicle rearview mirrors cannot effectively converge light, leading to errors or delays in the adjustment of the anti-glare function, affecting usability. The anti-glare function of a rearview mirror works by using two light sensors: one to monitor ambient light and the other to monitor glare from the driver's side. The anti-glare function is adjusted based on the detection results, essentially adjusting the intensity of the anti-glare color. If there are errors or delays in the adjustment, the anti-glare function may be activated during the day, affecting the driver's ability to see behind, while it may fail to activate effectively at dusk, interfering with the driver's vision.
[0079] Therefore, such as Figures 1-20 As shown, one aspect of this disclosure provides an optical device, including a light guide 1 and a first protrusion mechanism 2.
[0080] The light guide 1 is transparent and has a light-inlet surface 11 and a light-outlet surface 12. The light-outlet surface 12 is directed toward the photosensitive sensor 4.
[0081] The light guide 1 is able to transmit light, so that the optical light from the external environment or the glare from the cockpit can enter the light guide 1 through the light inlet surface 11 and then be emitted from the light outlet surface 12 to the photosensitive sensor 4 for detection.
[0082] The light-inlet surface 11 and / or the light-outlet surface 12 are provided with a first protrusion mechanism 2 at least in some positions. It is understood that the first protrusion mechanism 2 can be provided on the light-inlet surface 11, or on the light-outlet surface 12, or simultaneously on both the light-inlet surface 11 and the light-outlet surface 12, depending on the design requirements.
[0083] The first protrusion mechanism 2 is configured as a mesh pattern protruding from the light-inlet surface 11 or the light-outlet surface 12, so that the first protrusion mechanism 2 can make the light converge toward the photosensitive sensor 4.
[0084] In the above technical solution, the mesh pattern can refract light. That is, light entering the light guide 1 from the light-inlet surface 11 can be refracted by the mesh pattern, causing it to illuminate the photosensitive sensor 4. Similarly, light illuminating the light guide 1 and exiting from the light-outlet surface 12 can be refracted by the mesh pattern, illuminating the photosensitive sensor 4. This improves the light detection accuracy of the photosensitive sensor 4. Furthermore, the mesh pattern design expands the light acquisition range. Light from different angles or directions illuminating the light-inlet surface 11 or the light-outlet surface 12 can be refracted by the mesh pattern, causing light from different angles or directions to converge towards the photosensitive sensor 4. This allows the photosensitive sensor 4 to detect more light, further improving its light detection accuracy. This, in turn, improves the accuracy of adjusting the anti-glare function of mirror-reflective devices such as rearview mirrors, ensuring optimal performance.
[0085] Optionally, in one embodiment of this disclosure, the first protrusion mechanism 2 includes a plurality of first protrusions 21, which are spaced apart along the transverse and longitudinal directions, respectively.
[0086] The multiple first protrusions 21 are spaced apart along the transverse and longitudinal directions to form an interlaced structure, thereby creating a mesh-like pattern that enables the refraction of light from different angles or directions. It should be noted that the transverse and longitudinal directions here refer to the transverse or longitudinal directions relative to the light-inlet surface 11 or the light-outlet surface 12 of the light guide 1, and do not specifically refer to horizontal or vertical directions.
[0087] The number of first protrusions 21 can be set according to different design needs. In addition, the spacing between the first protrusions 21 can also be set according to different design needs. Multiple first protrusions 21 can be set at equal intervals or at unequal intervals.
[0088] Optionally, in one embodiment of this disclosure, the plurality of first protrusions 21 include a plurality of first protrusions 211, the first protrusions 211 extending along a first direction, and the plurality of first protrusions 211 being spaced apart along a transverse direction.
[0089] The first protrusion 211 is elongated and extends along the first direction, while multiple first protrusions 211 are spaced apart along the transverse direction. It can be understood that the first direction and the transverse direction are two directions.
[0090] Optionally, in some examples, the plurality of first protrusions 21 further include a plurality of second protrusions 213, the second protrusions 213 extending along a second direction, the plurality of second protrusions 213 being spaced apart along a longitudinal direction, and the first direction being angled to the second direction.
[0091] The second protrusion 213 is elongated and extends along the second direction, while multiple second protrusions 213 are spaced apart along the longitudinal direction. It can be understood that the second direction and the longitudinal direction are two separate directions.
[0092] It is understandable that among the multiple first protrusions 21, one part is a first protrusion 211 and the other part is a second protrusion 213. The first protrusion 211 and the second protrusion 213 extend in different directions and are spaced in different directions. The first protrusion 211 and the second protrusion 213 are arranged in a cross pattern, thereby forming a mesh pattern.
[0093] In other examples, the plurality of first protrusions 21 include a plurality of second protrusions 214, which are spaced apart along a second direction and also spaced apart along a longitudinal direction, with the first direction and the second direction forming an angle. The second protrusions 214 are block-shaped structures, and are relatively independent and spaced apart, allowing them to be spaced apart along both the second and longitudinal directions. It is understood that the second direction and the longitudinal direction are two separate directions.
[0094] It is understandable that among the multiple first protrusions 21, one part is a first protrusion 211 and the other part is a second protrusion 214. The first protrusion 211 can be spaced apart from the second protrusion 214, and the first protrusion 211 can be interlaced between two adjacent second protrusions 214 to form a mesh pattern.
[0095] In other examples, the plurality of first protrusions 21 may include a plurality of second protrusions 213 and a plurality of second protrusions 214. That is, the second protrusions 213 and the second protrusions 214 can be provided simultaneously, and can be set as needed, without further restrictions here.
[0096] Alternatively, in another embodiment of this disclosure, the plurality of first protrusions 21 include a plurality of first protrusions 212, the plurality of first protrusions 212 being spaced apart along a first direction and spaced apart along a transverse direction.
[0097] The first protrusion 212 is a block structure. Multiple first protrusions 212 are relatively independent and spaced apart, allowing them to be spaced apart along a first direction and also along a transverse direction. It can be understood that the first direction and the transverse direction are two directions.
[0098] Optionally, in some examples, the plurality of first protrusions 21 further include a plurality of second protrusions 213, the second protrusions 213 extending along a second direction, the plurality of second protrusions 213 being spaced apart along a longitudinal direction, and the first direction being angled to the second direction.
[0099] The second protrusion 213 is elongated and extends along the second direction, while multiple second protrusions 213 are spaced apart along the longitudinal direction. It can be understood that the second direction and the longitudinal direction are two separate directions.
[0100] It is understandable that among the multiple first protrusions 21, one part is a first protrusion 212 and the other part is a second protrusion 213. The first protrusion 212 can be spaced apart from the second protrusion 213, and the first protrusion 212 can be interspersed between two adjacent second protrusions 213 to form a mesh pattern.
[0101] In other examples, the plurality of first protrusions 21 include a plurality of second protrusions 214, which are spaced apart along a second direction and also spaced apart along a longitudinal direction, with the first direction and the second direction forming an angle. The second protrusions 214 are block-shaped structures, and are relatively independent and spaced apart, allowing them to be spaced apart along both the second and longitudinal directions. It is understood that the second direction and the longitudinal direction are two separate directions.
[0102] It is understandable that among the multiple first protrusions 21, one part is a first protrusion 212 and the other part is a second protrusion 214. The first protrusion 212 and the second protrusion 214 can be spaced apart, and the first protrusion 212 and the second protrusion 214 are also spaced apart from each other to form a mesh pattern.
[0103] In other examples, the plurality of first protrusions 21 may include a plurality of second protrusions 213 and a plurality of second protrusions 214. That is, the second protrusions 213 and the second protrusions 214 can be provided simultaneously, and can be set as needed, without further restrictions here.
[0104] Optionally, in another embodiment of this disclosure, the plurality of first protrusions 21 include a plurality of first protrusions 211 and a plurality of first protrusions 212, the first protrusions 211 extending along a first direction, the plurality of first protrusions 211 being spaced apart along a transverse direction, the plurality of first protrusions 212 being spaced apart along the first direction, and the plurality of first protrusions 212 being spaced apart along a transverse direction.
[0105] The first protrusion 211 is elongated and extends along a first direction. Multiple first protrusions 211 are spaced apart along a transverse direction. The first protrusion 212 is a block-like structure, with multiple first protrusions 212 being relatively opposed and spaced apart. Thus, multiple first protrusions 212 can be spaced apart along both the first and transverse directions. It is understood that the first protrusion 21 can consist partly of the first protrusion 211 and partly of the first protrusion 212, which can be configured as needed. The first protrusions 211 and first protrusions 212 can be independently located in a single area or spaced apart from each other; no further restrictions are imposed here. The first direction and the transverse direction are two directions.
[0106] Optionally, in some examples, the plurality of first protrusions 21 further include a plurality of second protrusions 213, the second protrusions 213 extending along a second direction, the plurality of second protrusions 213 being spaced apart along a longitudinal direction, and the first direction being angled to the second direction.
[0107] The second protrusion 213 is elongated and extends along the second direction, while multiple second protrusions 213 are spaced apart along the longitudinal direction. It can be understood that the second direction and the longitudinal direction are two separate directions.
[0108] It is understandable that a portion of the multiple first protrusions 21 are first protrusions 212 and first protrusions 211, and another portion are second protrusions 213, forming a mesh pattern.
[0109] In other examples, the plurality of first protrusions 21 include a plurality of second protrusions 214, which are spaced apart along a second direction and also spaced apart along a longitudinal direction, with the first direction and the second direction at an angle. The second protrusions 214 are block-shaped structures, and are relatively opposed and spaced apart, allowing them to be spaced apart along both the second and longitudinal directions. It is understood that the second direction and the longitudinal direction are two separate directions.
[0110] It is understandable that a portion of the multiple first protrusions 21 are first protrusions 212 and first protrusions 211, and another portion is second protrusions 214. The first protrusions 212 and first protrusions 211 can be spaced apart from the second protrusions 214 to form a mesh pattern.
[0111] In other examples, the plurality of first protrusions 21 may include a plurality of second protrusions 213 and a plurality of second protrusions 214. That is, the second protrusions 213 and the second protrusions 214 can be provided simultaneously, and can be set as needed, without further restrictions here.
[0112] Optionally, in one embodiment of this disclosure, the first direction is parallel to the longitudinal direction. When the first direction is parallel to the longitudinal direction, the extension direction of the first protrusion 211 is also along the longitudinal direction, and when the first protrusions 212 are spaced apart along the first direction, they are also spaced apart along the longitudinal direction.
[0113] Alternatively, in another embodiment of this disclosure, the second direction is parallel to the transverse direction. When the second direction is parallel to the transverse direction, the extension direction of the second protrusion 213 is also along the transverse direction, and when the second protrusions 214 are spaced apart along the second direction, they are also spaced apart along the transverse direction.
[0114] Alternatively, in another embodiment of this disclosure, the first direction is parallel to the longitudinal direction, while the second direction is parallel to the transverse direction.
[0115] In this configuration, when the first direction is parallel to the longitudinal direction, the first protrusion 211 extends in the longitudinal direction, and the first protrusions 212, when spaced apart along the first direction, are also spaced apart along the longitudinal direction. Similarly, when the second direction is parallel to the transverse direction, the second protrusion 213 extends in the transverse direction, and the second protrusions 214, when spaced apart along the second direction, are also spaced apart along the transverse direction. In some examples, the transverse direction and the longitudinal direction can be perpendicular, meaning the first direction and the second direction are perpendicular. This results in a more regular mesh pattern.
[0116] Optionally, in one embodiment of this disclosure, the light guide 1 is provided with an axis perpendicular to the light-inlet surface 11 or the light-outlet surface 12, and the area of the cross-section of the first protrusion 21 in the direction perpendicular to the axis gradually decreases along the direction away from the light guide 1. This arrangement facilitates light convergence, enabling light to be refracted at different angles or in different directions, thus achieving light convergence.
[0117] When the first protrusion 21 is provided on the light-inlet surface 11, the light guide 1 has an axis perpendicular to the light-inlet surface 11, and the cross-sectional area of the first protrusion 21 in the direction perpendicular to the axis of the light-inlet surface 11 gradually decreases. When the first protrusion 21 is provided on the light-outlet surface 12, the light guide 1 has an axis perpendicular to the light-outlet surface 12, and the cross-sectional area of the first protrusion 21 in the direction perpendicular to the axis of the light-inlet surface 11 gradually decreases.
[0118] Optionally, in one embodiment of this disclosure, the end of the first protrusion 21 facing away from the light guide 1 is configured as a curved surface. This configuration facilitates the refraction of light, enabling light to converge by refracting light from different angles or directions.
[0119] Optionally, in one embodiment of this disclosure, the light guide 1 is provided with an axis perpendicular to the light-inlet surface 11 or the light-outlet surface 12. In the direction perpendicular to the axis, the area of the first protrusion mechanism 2 is larger than the photosensitive area of the photosensitive sensor 4. This arrangement ensures that the first protrusion mechanism 2 can refract light from different directions or angles and illuminate the photosensitive sensor 4 as much as possible, avoiding situations where the area of the first protrusion mechanism 2 is too small, causing the refracted light to shine outside the photosensitive sensor 4 and affecting the detection effect.
[0120] Alternatively, in one embodiment of this disclosure, the optical device further includes a second protrusion mechanism 3.
[0121] At least a portion of one of the light-inlet surface 11 and the light-outlet surface 12 is provided with a first protrusion mechanism 2, and at least a portion of the other is provided with a second protrusion mechanism 3.
[0122] The second protrusion mechanism 3 is configured with straight grooves along the transverse or longitudinal direction, and the second protrusion mechanism 3 can cause light to converge toward the photosensitive sensor 4.
[0123] The second protrusion mechanism 3 can also refract light, causing the light to converge toward the photosensitive sensor 4. Thus, with the combined action of the first protrusion mechanism 2 and the second protrusion mechanism 3, the range of the direction and angle of light acquisition is expanded, more light can be acquired, and the light can be converged to the photosensitive sensor 4 to increase the amount of light.
[0124] In some examples, the light-inlet surface 11 is provided with a first protrusion mechanism 2, and the light-outlet surface 12 is provided with a second protrusion mechanism 3. In other examples, the light-inlet surface 11 is provided with a second protrusion mechanism 3, and the light-outlet surface 12 is provided with a first protrusion mechanism 2.
[0125] Optionally, in one embodiment of this disclosure, the second protrusion mechanism 3 includes a plurality of second protrusions 31, which are configured as strips. The plurality of second protrusions 31 are respectively arranged at intervals along the transverse direction or the longitudinal direction.
[0126] The plurality of second protrusions 31 are spaced apart in the transverse or longitudinal direction, and grooves can be formed between adjacent second protrusions 31, thereby forming a straight groove pattern that can refract light and cause the light to converge toward the photosensor 4. It can be understood that when the plurality of second protrusions 31 are spaced apart in the transverse direction, the plurality of second protrusions 31 can extend in the longitudinal direction. When the plurality of second protrusions 31 are spaced apart in the longitudinal direction, the plurality of second protrusions 31 can extend in the transverse direction.
[0127] Optionally, in one embodiment of this disclosure, the light guide 1 is provided with an axis perpendicular to the light emitting surface 12 or the light entering surface 11, and the area of the cross-section of the second protrusion 31 gradually decreases in the direction perpendicular to the axis along the direction away from the light guide 1. This arrangement facilitates light convergence, enabling light to be refracted at different angles or in different directions.
[0128] When the second protrusion 31 is provided on the light-inlet surface 11, the light guide 1 has an axis perpendicular to the light-inlet surface 11, and the cross-sectional area of the second protrusion 31 in the direction perpendicular to the axis of the light-inlet surface 11 gradually decreases. When the second protrusion 31 is provided on the light-outlet surface 12, the light guide 1 has an axis perpendicular to the light-outlet surface 12, and the cross-sectional area of the second protrusion 31 in the direction perpendicular to the axis of the light-inlet surface 11 gradually decreases.
[0129] Optionally, in one embodiment of this disclosure, the end of the second protrusion 31 facing away from the light guide 1 is configured as a pointed cone. This configuration facilitates the refraction of light, enabling the refraction of light from different angles or directions, thereby converging the light.
[0130] Optionally, in one embodiment of this disclosure, the light guide 1 is provided with an axis perpendicular to the light-inlet surface 11 or the light-outlet surface 12. In the direction perpendicular to the axis, the area of the second protrusion mechanism 3 is larger than the photosensitive area of the photosensitive sensor 4. This arrangement ensures that the second protrusion mechanism 3 can refract light from different directions or angles and illuminate the photosensitive sensor 4 as much as possible, avoiding situations where the area of the second protrusion mechanism 3 is too small, causing the refracted light to shine outside the photosensitive sensor 4 and affecting the detection effect.
[0131] Optionally, in one embodiment of this disclosure, the light guide 1 includes a plate 14 and a mounting leg 15. The two opposite sides of the plate 14 are respectively configured as a light-inlet surface 11 and a light-outlet surface 12, and one end of the mounting leg 15 is connected to the plate 14.
[0132] The mounting feet 15 are used to mount and fix the plate 14, which can be fixed in front of the photosensor 4, so that the light-emitting surface 12 faces the photosensor 4. In some examples, there are two mounting feet 15, which are equally arranged and are equipped with hooks to achieve a snap-fit fixation. In addition, both the plate 14 and the mounting feet 15 can transmit light.
[0133] Optionally, in one embodiment of this disclosure, the light guide 1 is provided with an axis perpendicular to the light emitting surface 12, the photosensitive sensor 4 is provided in a direction perpendicular to the axis of the light emitting surface 12, and the first protrusion mechanism 2 can cause the light to converge in a direction perpendicular to the axis of the light emitting surface 12.
[0134] A second aspect of this disclosure also provides an anti-glare mirror reflection device, including a housing 5, a photosensor 4, and the aforementioned optical components.
[0135] Both the optical components and the photosensor 4 are housed within the housing 5, with the light-emitting surface 12 of the optical components facing the photosensor 4. The optical components refract and converge light rays from different directions or angles onto the photosensor 4, increasing the amount of light detected by the photosensor 4 and thus improving detection accuracy.
[0136] Optionally, the anti-glare mirror reflection device also includes a reflector assembly 6, which is connected to the housing 5 and located in front of the optics. The color depth of the reflector assembly 6 can be adjusted to achieve the anti-glare function. It also includes structures such as a circuit board for control and adjustment.
[0137] Optionally, in one embodiment of this disclosure, the anti-glare mirror reflection device is a rearview mirror. It can be an exterior rearview mirror or an interior rearview mirror.
[0138] A third aspect of this disclosure also provides a vehicle that includes the aforementioned optical device or the aforementioned anti-glare mirror reflection device.
[0139] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments.
