Description

Car rearview mirror and vehicle Technical Field

[0001] The present application relates to the field of vehicle manufacturing, and in particular to a vehicle-mounted rearview mirror and a vehicle using the vehicle-mounted rearview mirror. Background Art

[0002] The rearview mirror installed in the car cabin is an important tool for the driver to observe the road conditions behind him while driving. However, the strong light emitted by the headlights of the following vehicles can also be reflected by the rearview mirror, which can seriously disturb the driver. Therefore, the anti-glare function of the rearview mirror is particularly important.

[0003] Furthermore, as cars (especially those with autonomous driving capabilities) become increasingly popular, the requirements for their safety and intelligence are also increasing. Accordingly, automakers and automotive parts manufacturers have begun embedding monitoring systems within the vehicle's cabin to detect the driver's driving status and whether children or pets have been left behind. Existing in-cabin monitoring systems generally have multiple independent modules, such as driver monitoring and passenger monitoring. The installation locations of these monitoring modules are relatively arbitrary (various manufacturers have different standards). The need to install both rearview mirrors and multiple independent monitoring modules within the vehicle cabin results in a cluttered interior layout.

When the light intensity obtained by the second optical sensor is greater than the light intensity obtained by the third optical sensor, the transmittance of the anti-glare layer decreases.

[0016] In some embodiments of the present application, the first optical sensor is a camera; the second optical sensor and the third optical sensor are photosensors.

The anti-glare layer in the glass component has an anti-glare mode and a non-anti-glare mode, and can change the transmittance according to the brightness of the image collected by the first optical sensor. In the anti-glare mode, the light transmittance of the anti-glare layer is low (the light absorption rate is high), so that the reflectivity of the entire vehicle-mounted rearview mirror is low, which can eliminate the interference of glare on the driver. In the non-anti-glare mode, the light transmittance of the anti-glare layer is high (the light absorption rate is low), so that the reflectivity of the entire vehicle-mounted rearview mirror is high, which is convenient for the driver to observe the road conditions behind the car. After changing the structure of the glass component of the vehicle-mounted rearview mirror and combining it with the first optical sensor, it is possible to keep the overall thickness of the vehicle-mounted rearview mirror thin while realizing multiple functions such as anti-glare and monitoring, and at the same time reduce the changes to the existing car cabin layout to a minimum, solving the problem of messy car cabin layout in a relatively economical way.

[0029] Figure 2 is a schematic diagram of the structure of the glass assembly in Figure 1:

[0030] FIG3 is a schematic diagram of the vehicle rearview mirror shown in FIG1 being installed in a vehicle cabin. DETAILED DESCRIPTION

[0031] To make the purpose, technical solutions, and advantages of the invention more clear, the invention is further described in detail below with reference to the accompanying drawings and specific embodiments. Although the accompanying drawings show exemplary embodiments of the present application, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. Instead, these embodiments are provided to facilitate a more thorough understanding of the present application and to fully convey the concepts of the present application to those skilled in the art.

[0032] As shown in Figures 1 and 2, this embodiment provides a vehicle rearview mirror, comprising a housing 10, a glass assembly 20 with an anti-glare layer 22, and a first optical sensor 30. The glass assembly 20 is disposed on the housing 10 and has at least one light-through hole 21 formed therein. The first optical sensor 30 is disposed within the housing 10. The anti-glare layer 22 of the glass assembly 20 is capable of varying its transmittance according to the brightness of the image captured by the first optical sensor 30. The first optical sensor 30 is located on the rear side of the glass assembly 20 (on the right side as shown in Figure 1) and adjacent to the light-through hole 21; alternatively, at least a portion of the first optical sensor 30 is embedded within the light-through hole 21 and does not protrude from the front side of the glass assembly 20 (on the left side as shown in Figure 1).

[0033] In this embodiment, the anti-glare layer 22 can employ a physical anti-glare method. For example, the anti-glare layer 22 includes a polarizer, a glass substrate, an electrode layer, a liquid crystal layer, etc. The liquid crystal layer can be in TN (Twisted Nematic) mode or ADS (Advanced Super Dimension Switch) mode. By applying a voltage to the liquid crystal layer, the transmittance of the anti-glare layer 22 is changed. The anti-glare layer 22 can also employ a chemical anti-glare method. For example, the anti-glare layer 22 includes a light-transmitting layer, an electrode layer, an electrochromic layer, etc. The electrochromic layer is made of a chemical substance. By adjusting the chemical properties of the chemical substance in a desired direction, the transmittance of the anti-glare layer 22 is changed. The above-mentioned anti-glare layer 22 structure is well documented in the prior art and will not be repeated here.

[0034] In this embodiment, the housing 10 includes a front housing 11 , a middle housing 12 , and a rear housing 13 that are fixedly connected in sequence (forming a stacked structure). The glass assembly 20 is disposed on the outer surface of the front housing 11 .

[0035] In this embodiment, the first optical sensor 30 is a camera, which primarily comprises a mainboard 31 with an image acquisition chip, a lens base 32, and a lens 33. The mainboard 31 is fixed to the central housing 12. The lens base 32 is fixed to the mainboard 31 (with a dustproof seal disposed therebetween). The lens 33 is bonded to the lens base 32. The lens 33 passes through a clearance cutout in the front housing 11 and then fits into the light aperture 21 of the glass assembly 20.

[0036] Those skilled in the art should be able to understand that the first optical sensor 30 can adopt an existing camera, which is hidden behind the light hole 21 of the glass component 20 or embedded in the light hole 21 of the glass component 20, which is not easy to be discovered and can also have a good field of view. The anti-glare layer 22 in the glass component 20 has an anti-glare mode and a non-anti-glare mode, and can change the transmittance according to the brightness of the image captured by the first optical sensor 30. In the anti-glare mode, the light transmittance of the anti-glare layer 22 is low (the light absorption rate is high), so that the reflectivity of the entire vehicle rearview mirror is low, which can eliminate the interference of glare to the driver. In the non-anti-glare mode, the light transmittance of the anti-glare layer 22 is high (the light absorption rate is low), so that the reflectivity of the entire vehicle rearview mirror is high, which makes it easier for the driver to observe the road conditions behind the vehicle. By changing the structure of the glass component 20 of the vehicle rearview mirror and combining it with the first optical sensor 30, the overall thickness of the vehicle rearview mirror can be kept relatively thin while achieving multiple functions such as anti-glare and monitoring. At the same time, the changes to the existing layout of the car cabin are reduced to a minimum, solving the problem of a messy layout in the car cabin in a relatively economical way.

[0037] Furthermore, the light hole 21 is a non-through hole so that the front side of the glass component 20 can remain flat, and at least a portion of the first optical sensor 30 is embedded into the light hole 21 from the rear side of the glass component 20 .

[0038] Optionally, the light-through hole 21 is a blind hole formed on the rear side of the glass component 20 and cannot be observed from the front side of the glass component 20 .

[0039] Those skilled in the art should be able to understand that the front side of the glass assembly 20 is light-transmissive. After the first optical sensor 30 is embedded in the light-through hole 21, it does not hinder its image collection, and can also use the front side of the glass assembly 20 to conceal it, thereby keeping the front side of the entire vehicle rearview mirror flat and beautiful in appearance.

[0040] 1 and 2 , the vehicle rearview mirror provided in this embodiment includes a near-infrared light source 40 disposed on a housing 10. A first optical sensor 30 is capable of collecting light of a corresponding wavelength band emitted by the near-infrared light source 40 and generating image information. The near-infrared light source 40 is located behind the glass assembly 20 and adjacent to the light aperture 21; alternatively, at least a portion of the near-infrared light source 40 is embedded in the light aperture 21 and does not protrude from the front side of the glass assembly 20.

[0041] In this embodiment, the near-infrared light source 40 is a lamp board with a near-infrared light source. The near-infrared light source 40 is fixedly connected to the middle shell 12 by screws. The near-infrared light source passes through the avoidance hollow on the front shell 11 and is then embedded in the light hole 21 of the glass assembly 20.

[0042] Those skilled in the art will appreciate that the near-infrared light source 40 can actively emit near-infrared light (e.g., 850nm or 940nm infrared light) to reduce interference from ambient light, allowing the first optical sensor 30 to more accurately capture images within the vehicle. The near-infrared light source 40 can also be concealed behind or embedded within the light aperture 21 of the glass assembly 20, thereby reducing reddening and alleviating driver discomfort. Furthermore, the near-infrared light source 40 does not affect the overall exterior shape of the vehicle rearview mirror, minimizing changes to the existing interior layout of the vehicle, economically resolving the problem of cluttered interior layout.

[0043] Furthermore, the light-through hole 21 is a non-through hole so that the front side of the glass component 20 can remain flat, and at least a portion of the near-infrared light source 40 is embedded into the light-through hole 21 from the rear side of the glass component 20. The light-through hole 21 adjacent to or embedded in the near-infrared light source 40 and the first optical sensor 30 is the same or different.

[0044] Optionally, the light hole 21 is a blind hole formed on the rear side of the glass assembly 20 and cannot be observed from the front side of the glass assembly 20. In addition, the light holes 21 in which the near-infrared light source 40 and the first optical sensor 30 are embedded are different, that is, another light hole 21 is formed on the glass assembly 20 for the near-infrared light source 40.

[0045] Those skilled in the art should be able to understand that the front side of the glass assembly 20 is light-transmissive. After the near-infrared light source 40 is embedded in the light-through hole 21, the front side of the glass assembly 20 can be used to conceal it, reduce the red exposure phenomenon, and reduce the driver's discomfort, while keeping the front side of the entire vehicle rearview mirror flat and beautiful in appearance.

[0046] 1 and 2 , the vehicle rearview mirror provided in this embodiment further includes a second optical sensor 50 disposed on the housing 10. The anti-glare layer 22 is capable of varying its transmittance according to the light intensity detected by the second optical sensor 50. The second optical sensor 50 is located on the rear side of the glass assembly 20 and adjacent to the light aperture 21. Alternatively, at least a portion of the second optical sensor 50 is embedded in the light aperture 21 and does not protrude from the front side of the glass assembly 20.

[0047] In this embodiment, the second optical sensor 50 is a photosensor, which primarily comprises a front light guide 51 and a front light sensor board 52 with a photosensor. The front light sensor board 52 is fixedly connected to the middle housing 12 via screws. The front light guide 51 is mounted on the front light sensor board 52, passes through a cutout in the front housing 11, and then is embedded in the light hole 21 of the glass assembly 20.

[0048] Those skilled in the art will appreciate that the anti-glare layer 22 can be independently controlled to change its transmittance based on changes in light intensity detected by the second optical sensor 50, or can be collaboratively controlled by the first and second optical sensors 30, 50. The second optical sensor 50 can also be concealed behind or embedded within the light aperture 21 of the glass assembly 20, thereby maintaining the overall appearance of the vehicle rearview mirror and minimizing changes to the existing vehicle interior layout, thereby economically resolving the issue of cluttered interior layout.

[0049] Furthermore, the light-through hole 21 is a non-through hole so that the front side of the glass component 20 can remain flat, and at least a portion of the second optical sensor 50 is embedded in the light-through hole 21 from the rear side of the glass component 20. The light-through holes 21 adjacent to or embedded in the second optical sensor 50 and the first optical sensor 30 are the same or different.

[0050] Optionally, the light through hole 21 is a blind hole formed on the rear side of the glass assembly 20 and cannot be observed from the front side of the glass assembly 20. Furthermore, the light through holes 21 in which the second optical sensor 50 and the first optical sensor 30 are embedded are different, and the light through holes 21 in which the second optical sensor 50 and the near-infrared light source 40 are embedded are also different. That is, another light through hole 21 is formed on the glass assembly 20 solely for the second optical sensor 50.

[0051] Similarly, those skilled in the art should be able to understand that the front side of the glass assembly 20 is light-transmissive. After the second optical sensor 50 is embedded in the light-through hole 21, it can use the front side of the glass assembly 20 to conceal it, keeping the front side of the entire vehicle rearview mirror flat and beautiful in appearance.

[0052] 1 and 2 , further, the housing 10 has a first side and a second side different from the first side, a second optical sensor 50 is disposed on the first side, and another third optical sensor 60 is disposed on the second side. When the light intensity obtained by the second optical sensor 50 is greater than the light intensity obtained by the third optical sensor 60, the transmittance of the anti-glare layer 22 decreases.

[0053] In this embodiment, as described above, the housing 10 includes a front housing 11, a middle housing 12, and a rear housing 13 that are fixedly connected in sequence (forming a stacked structure). The first side is the side of the front housing 11 (the side facing the rear of the vehicle), and the second side is the side of the rear housing 13 (the side facing the front of the vehicle). In other words, the first side and the second side are opposite sides. Of course, the second side can also refer to the side facing the side of the vehicle body.

[0054] Optionally, the third optical sensor 60 is a photosensor, which mainly includes a rear light guide column 61 and a rear photosensitive light board 62 with a photosensor. The rear photosensitive light board 62 is fixedly connected to the inner side of the rear housing 13 by screws, and the rear housing 13 is formed with a hollow to avoid the rear light guide column 61.

[0055] Those skilled in the art will appreciate that by comparing the light intensities captured by the second optical sensor 50 and the third optical sensor 60, it is possible to determine whether strong light is illuminating the rearview mirror from behind the vehicle. If there is strong light illuminating the rearview mirror, the light intensity captured by the second optical sensor 50 will be significantly higher than that captured by the third optical sensor 60, indicating that the anti-glare mode is engaged. Conversely, the mirror is in non-anti-glare mode. Compared to using only the second optical sensor 50, adding the third optical sensor 60 allows the rearview mirror to switch between anti-glare and non-anti-glare modes more accurately.

[0056] 1 and 2 , the glass assembly 20 further includes an anti-glare layer 22, an inner glass sheet 23, and an outer glass sheet 24. The inner glass sheet 23 is coated on the housing 10 and is used to reflect light, the anti-glare layer 22 is coated on the inner glass sheet 23 and is used to change the light transmittance, and the outer glass sheet 24 is coated on the anti-glare layer 22 and is used to transmit light.

[0057] The anti-glare layer 22 is formed with a first sub-aperture 22a, and the inner glass sheet 23 is formed with a second sub-aperture 23a, so that the first sub-aperture 22a and the second sub-aperture 23a can overlap to form the light-through hole 21. The surface of the outer glass sheet 24 is flat. A control switch 22b (control circuit) is provided on the anti-glare layer 22, and this control circuit is electrically connected to the mainboard 31 of the first optical sensor 30. Optionally, avoidance holes are formed in the front housing 11 and the middle housing 12, respectively, so that the control switch 22b (control circuit) can be connected to the mainboard 31 through these avoidance holes. The mainboard 31 can change the light transmittance of the anti-glare layer 22 (switching the anti-glare layer 22 between anti-glare mode and non-anti-glare mode) by controlling the switch 22b according to the brightness of the image captured by the lens 33. The glass assembly 30 is adhered to the housing 10 (front housing 11) using adhesive 25. The adhesive 25 defines a clearance hole 25a, which corresponds to the positions of the first sub-light hole 22a and the second sub-light hole 23a described above, thereby not interfering with the formation of the light-through hole 21. The diameter (or area) of the clearance hole 25a can be larger than the light-through hole 21. Alternatively, the glass assembly 30 can be fixedly attached to the housing 10 (front housing 11) using one or more of the following methods: adhesive bonding, screw fastening, or gland fixing.

[0058] Optionally, the outer glass sheet 24 can be ordinary glass that is transparent to light and coated with an antireflection coating. The inner glass sheet 23 can be mirror glass coated with a reflective coating (to achieve specular reflection), with the reflective coating forming a shield at the second sub-aperture 23a. The antireflection coating and reflective coating can control the transmittance and reflectivity of the glass assembly 30 for light of corresponding wavelengths, thereby meeting the different needs of various scenarios.

[0059] Those skilled in the art should be able to understand that the first sub-light hole 22a and the second sub-light hole 23a of the anti-glare layer 22 and the inner glass sheet 24 are used to accommodate the first optical sensor 20 and / or the second optical sensor 50 and / or the third optical sensor 60, and the outer glass sheet 24 can be manufactured into a flat surface without openings, so as to achieve the above-mentioned effect of not hindering the operation of the sensor but also concealing the sensor, thereby ensuring the beautiful appearance of the entire vehicle rearview mirror.

[0060] Another embodiment of the present application provides a vehicle, comprising any one of the vehicle-mounted rearview mirrors described in the above embodiments. Further, the vehicle-mounted rearview mirror is installed on the upper side of the front windshield of the vehicle.

[0061] Continuing with Figures 1 and 2, and in conjunction with Figure 3, the vehicle rearview mirror is further movably connected to the vehicle via a rotating connector 70. The rotating connector 70 is used to provide support force, allowing the vehicle rearview mirror to be fixed in any orientation within the vehicle cabin. For example, it can be oriented only toward the main driver's seat; or it can be oriented toward both the main driver's seat and the rear middle seat. The vehicle includes a processor configured to identify the status information of the seat's occupant based on the image captured by the vehicle rearview mirror's first optical sensor 30.

[0062] Optionally, the first optical sensor 20 can collect information about the driver's facial expressions, eyes, and body movements, and the processor can recognize the information based on a pre-calibrated neural network. The recognition results can be used to determine whether the driver is driving fatigued.

[0063] In this embodiment, the rotating connector 70 includes a ball bracket 71, a ball bracket base 72, and a spring 73. The rear housing 13 has a hollow formed therein for the ball head of the ball bracket 71 to pass through. The ball bracket base 72 is fixedly connected to the rear housing 13 by screws. The spring 73 is mounted on a coupling portion 72a of the ball bracket base 72. The ball head 71a of the ball bracket 71 passes through the hollowed-out portion of the rear housing 13 to form a rotating connection with the ball bracket base 72. The mounting portion 71b of the ball bracket 71 is fixed inside the vehicle cabin (e.g., on the front windshield).

[0064] Furthermore, the processor is configured to generate motion control instructions based on the state information for instructing the vehicle to change its motion state. For example, it may enter an autonomous driving mode or a manual driving mode. Another example is to maintain a preset distance from the vehicle ahead, perform emergency braking, or maintain lane.

[0065] Furthermore, the processor is configured to identify image information within a preset seat area based on the image captured by the first optical sensor 30 of the vehicle rearview mirror, compare the identified image information with pre-stored image information in the processor, and determine whether an object has been left on the seat.

[0066] In this embodiment, the vehicle's processor pre-stores image information (including at least image features of the seat surface and possibly also the outer contour features of the seat back) of a seat in an idle state (no one sitting or carrying any objects) within a preset seating area. When the image information acquired by the first optical sensor 30 is inconsistent with the pre-stored image information in the processor (e.g., determined through a comprehensive similarity estimation), the recognition result can be used to determine whether an object (e.g., a child, pet, or package) has been left in the idle seat. Based on this determination, the processor can generate a safety control instruction instructing the vehicle to issue a warning sound (e.g., a horn or a vibration of the vehicle key) to prompt the driver to check the seat.

[0067] In other embodiments, the system can also determine whether an object has been left on a seat by comparing the recognized image information with pre-stored image information in the processor after the vehicle is turned off and / or the key has moved a preset distance away from the vehicle. This "pre-set distance" can be determined using UMB ultra-wideband positioning or Bluetooth positioning technology.

[0068] Furthermore, the processor is also configured to: identify image information of living things (such as people and pets) on the vehicle based on the images periodically collected by the first optical sensor of the vehicle-mounted rearview mirror; and judge the safety index and / or health index of the living things based at least on the image information.

[0069] Furthermore, judging the safety index and / or health index of the living being at least based on the image information includes: judging the safety index of the living being based on the image information of the living being on the vehicle, by comparing it with pre-stored image information representing dangerous actions; and / or judging the health index of the living being based on the image information of the living being on the vehicle, by comparing it with pre-stored image information representing dangerous states.

[0070] Specifically, if a life form is judged to be performing a dangerous action, such as standing or leaning out of a car window, a low life form safety index or safety risk warning will be output. If a life form is judged to be in a dangerous state, such as pain, coma, or bleeding, a low life form health index or safety risk warning will be output.

[0071] In some embodiments, if the vehicle has data permission to access the smart wearable device worn by the living being, the health index of the living being can also be jointly determined based on the image information and the physiological parameters collected from the smart wearable device worn by the living being.

[0072] Furthermore, the processor is configured to generate a safety control instruction for instructing the vehicle to emit a warning sound based on the judgment result.
