Description of Related Art

With frequent commercial activities and the rapid expansion of transportation logistics, people are more dependent on the mobile vehicle such as car or motorcycle. At the same time, drivers are paying more and more attention to the protection of their lives and property when driving, and therefore, in addition to the performance and the comfort of the mobile vehicle, it is also considered whether the mobile vehicle to be purchased provides sufficient safety guards or auxiliary devices. Under this trend, in order to increase the safety of vehicles, automobile manufacturers or vehicle equipment design manufacturers have developed various driving safety protection devices or auxiliary devices, such as rearview mirrors, driving recorders, a panoramic image instant displaying of blind vision areas, a global positioning system that records the driving path at any time, and etc.

In addition, with the rapid development of digital cameras and computer visions in daily life, the digital cameras have been applied to driving assistance systems, hoping to reduce the accident rate of traffic accidents through the application of artificial intelligence.

Take a conventional rearview mirror as an example, when a driver changes lanes or turns, most of the conventional rearview mirror is used to observe and determine the presence or absence of objects outside of the vehicle. However, most of the rearview mirrors have limitations and disadvantages in use under certain driving conditions. For example, when driving at night, the driver's pupil is in an enlarged state in the dark environment just like the shutter of the camera for providing more optical signals to the optic nerve. In such a state, the driver's eyes are extremely sensitive to sudden light. Usually, the rearview mirror reflects the front light from the overtaking or subsequent vehicles, which causes the driver to have a visual dizziness, so that the driver's visual ability will be rapidly reduced in an instant, increasing the driver's reaction time that front obstacles become visible.

Therefore, how to effectively control the light reflectivity and penetration rate of the rearview mirror to reduce the light entering the driver's eyes so as to improve the driver's visual dizziness and to improve driving safety is one of the important problems to be solved.

BRIEF SUMMARY OF THE INVENTION

The present invention provides a movable carrier auxiliary system which is a vehicle electronic rear-view mirror as an example and includes a first transparent assembly, a second transparent assembly, an electro-optic medium layer, at least one transparent electrode, at least one reflective layer, and at least one transparent conductive layer. The electro-optic medium layer is disposed between the first transparent assembly and the second transparent assembly. The transparent electrode could be disposed between the first transparent assembly and the electro-optic medium layer. The electro-optic medium layer could be disposed between the first transparent assembly and the reflective layer. The transparent electrode could be disposed between the electro-optic medium layer and the reflective layer. In this way, when the electro-optic medium layer is enabled by applying an external voltage or current, the optical properties of the electro-optic medium layer in the visible wavelength range (e.g. light transmittance, light reflectivity, or absorbance) could produce stable reversible change, thereby enabling color and transparency changes.

When an intensity of the external light is too strong to affect the driver's eyes, the external light is absorbed by the electro-optic medium layer to be in a matt state after the light beam reaches the electro-optic medium layer, so that the vehicle electronic rearview mirror is switched to an anti-glare mode. On the other hand, when the electro-optic medium layer is disenabled, the electro-optic medium layer is transparent. At this time, the external light passes through the electro-optic medium layer to be reflected by the reflective layer, so that the vehicle electronic rear-view mirror is switched to a mirror mode.

The length of the contour curve of the maximum effective radius of the side of the second lens object is represented by ARS21, the thickness of the second lens on the optical axis is TP2, the ratio between the two is ARS21/TP2, and the contour of the maximum effective radius of the side of the second lens image The length of the curve is represented by ARS22, and the ratio between it and TP2 is ARS22/TP2.

For any surface of any lens, the profile curve length within a half of the entrance pupil diameter (HEP) affects the ability of the surface to correct aberration and differences between optical paths of light in different fields of view. With longer profile curve length, the ability to correct aberration is better. However, the difficulty of manufacturing increases as well. Therefore, the profile curve length within a half of the entrance pupil diameter (HEP) of any surface of any lens has to be controlled. The ratio between the profile curve length (ARE) within a half of the entrance pupil diameter (HEP) of one surface and the thickness (TP) of the lens, which the surface belonged to, on the optical axis (i.e., ARE/TP) has to be particularly controlled.

The profile curve length of a half of the entrance pupil diameter (HEP) of the object-side surface of the second lens is denoted by ARE21, the thickness of the second lens on the optical axis is TP2, and the ratio between these two parameters is ARE21/TP2; the profile curve length of a half of the entrance pupil diameter (HEP) of the image-side surface of the second lens is denoted by ARE22, and the ratio between ARE22 and TP2 is ARE22/TP2. For any surface of other lenses in the optical image capturing system, the ratio between the profile curve length of a half of the entrance pupil diameter (HEP) thereof and the thickness of the lens which the surface belonged to is denoted in the same manner.

A movable carrier auxiliary system of the present invention includes a structural design and an optical design, wherein structural embodiments will be described first.

A movable carrier auxiliary system which is a vehicle electronic rear-view mirror0100as an example according to a first structural embodiment of the present invention is illustrated inFIG. 1A.FIG. 1Bis a simplified sectional view ofFIG. 1Aseen from a right shorter lateral side. The vehicle electronic rear-view mirror0100could be disposed on a transport which is a vehicle as an example to assist in the driving of the vehicle or to provide information about driving. More specifically, the vehicle electronic rear-view mirror0100could be an inner rear-view mirror disposed inside of the vehicle or could be an outer rear-view mirror disposed outside of the vehicle, which are used to assist the driver in understanding the location of other vehicles. However, this is not a limitation of the present invention. In addition, the transport is not limited to be a vehicle, but could be other types of vehicles, such as land, water, air transport, and etc.

The vehicle electronic rear-view mirror0100is assembled in a casing0110, wherein the casing0110has an opening (not shown). More specifically, the opening of the casing0110overlaps with a reflective layer0190of the vehicle electronic rear-view mirror0100(shown inFIG. 1B). In this way, an external light could be transmitted to the reflective layer0190located inside of the casing0110through the opening, so that the vehicle electronic rear-view mirror0100functions as a mirror. When the driver drives the vehicle and faces the opening, for example, the driver could see the external light reflected by the vehicle electronic rear-view mirror0100, thereby knowing the position of the rear vehicle.

Referring toFIG. 1B, the vehicle electronic rear-view mirror0100includes a first transparent assembly0120and a second transparent assembly0130, wherein the first transparent assembly0120faces the driver, and the second transparent assembly0130is disposed on a side away from the driver. More specifically, the first transparent assembly0120and the second transparent assembly0130are translucent substrates, wherein a material of the translucent substrates could be glass for example. However, the material of the translucent substrates is not a limitation of the present invention. In other embodiments, the material of the translucent substrates could be plastic, quartz, PET substrate, or other applicable materials, wherein the PET substrate has the advantages of low cost, easy manufacture, and extremely thinness, in addition to packaging and protection effects.

In the current structural embodiment, the first transparent assembly0120includes a first incidence surface0122and a first exit surface0124, wherein an incoming light image from the rear of the driver enters the first transparent assembly0120via the first incidence surface0122, and is emitted via the first exit surface0124. The second transparent assembly0130includes a second incidence surface0132and a second exit surface0134, wherein the second incidence surface0132faces the first exit surface0124, and a gap is formed between the second incidence surface0132and the first exit surface0124by an adhesive0114. After the incoming light image being emitted via the first exit surface0124, the incoming light image enters the second transparent assembly0130via the second incidence surface0132, and is emitted via the second exit surface0134.

An electro-optic medium layer0140is disposed in the gap between the first exit surface0124of the first transparent assembly0120and the second incidence surface0132of the second transparent assembly0130. At least one transparent electrode0150is disposed between the first transparent assembly0120and the electro-optic medium layer0140. The electro-optic medium layer0140is disposed between the first transparent assembly0120and at least one reflective layer0190. A transparent conductive layer0160is disposed between the first transparent assembly0120and the electro-optic medium layer0140. Another transparent conductive layer0160is disposed between the second transparent assembly0130and the electro-optic medium layer0140. An electrical connector0170is electrically connected to the transparent conductive layer0160, and another electrical connector0170is electrically connected to the transparent electrode0150, thereby to transmit electrical energy to the electro-optic medium layer0140to change a transparency of the electro-optic medium layer0140. When a brightness of the incoming light image exceeds a certain brightness (e.g. a strong headlight from the rear of the vehicle), an image sensing device which is a glare sensor0112as an example electrically connected to a control member0180receives the light energy and convert it into a signal, and the control member0180determines whether the brightness of the incoming light image exceeds a predetermined brightness, and if a glare is generated, the electrical energy is provided to the electro-optic medium layer0140by the electrical connector0170to generate an anti-glare performance. If the external light image is too strong, it will cause glare effect and affect the driver's eyes, thus endangering driving safety. More specifically, when an environment brightness inside of the movable carrier sensed by the image sensing device decreases, a brightness of the incoming light image decreases, while when the environment brightness rises, the brightness of the incoming light image rises. In an embodiment, the electrical connector could include at least one of a flexible circuit board, a copper foil, and an electric wire.

In addition, the transparent electrode0150and the reflective layer0190could respectively cover entire surface of the first transparent assembly0120and entire surface of the second transparent assembly0130. However, this is not a limitation of the present invention. In the current structural embodiment, a material of the transparent electrode0150could be selected from metal oxides such as indium tin oxide, indium zinc oxide, aluminum tin oxide, aluminum zinc oxide, indium antimony zinc oxide, other suitable oxides, or a stacked layer of at least two of the foregoing oxides. Moreover, a material of the reflective layer0190could be selected from a material containing cerium oxide, or could be a material which is conductive selected from a group consisting of at least one of silver (Ag), copper (Cu), aluminum (Al), titanium (Ti), chromium (Cr), molybdenum (Mo) or its alloy, or could be a transparent conductive material. However, the material of the transparent electrode0150and the material of the reflective layer0190are not a limitation of the present invention. In other embodiments, the material of the transparent electrode0150and the material of the reflective layer0190could be other types of materials.

The electro-optic medium layer0140could be made of an organic material or an inorganic material. However, this is not a limitation of the present invention. In the current structural embodiment, the electro-optic medium layer0140could be an electrochromic material. The electro-optic medium layer0140is disposed between the first transparent assembly0120and the second transparent assembly0130and is disposed between the first transparent assembly0120and the reflective layer0190. More specifically, the transparent electrode0150is disposed between the first transparent assembly0120and the electro-optic medium layer0140(i.e., electrochromic material layer). In a structural embodiment, the reflective layer0190could be disposed between the second transparent assembly0130and the electro-optic medium layer0140. In other embodiments, the electro-optic medium layer could be a polymer dispersed liquid crystal (PDLC) layer or a suspended particle device (SPD) layer. In addition, in the current structural embodiment, the vehicle electronic rear-view mirror0100further includes an adhesive0114located between the first transparent assembly0120and the second transparent assembly0130and surrounding the electro-optic medium layer0140. The electro-optic medium layer0140is co-packaged by the adhesive0114, the first transparent assembly0120, and the second transparent assembly0130.

In the current structural embodiment, the transparent conductive layer0160is disposed between the electro-optic medium layer0140and the reflective layer0190. More specifically, the transparent conductive layer0160could be used as an anti-oxidation layer of reflective layer0190, so that the electro-optic medium layer0140could be prevented from being in contact with the reflective layer0190, thereby preventing the reflective layer0190being corroded by organic materials, providing the vehicle electronic rear-view mirror0100of the current structural embodiment a longer service life. In addition, the electro-optic medium layer0140is co-packaged by the adhesive0114, the transparent electrode0150, and the transparent conductive layer0160. In the current structural embodiment, the transparent conductive layer0160contains at least one material selected from a group consisting of indium tin oxide (ITO), indium zinc oxide (IZO), Al-doped ZnO (AZO), or Fluorine-doped tin oxide.

In the current structural embodiment, the vehicle electronic rear-view mirror0100could optionally provide with the electrical connector0170. For instance, in an structural embodiment, a conducting wire or a conducting structural is electrically connected to the transparent electrode0150and the reflective layer0190, so that the transparent electrode0150and the reflective layer0190could be electrically connected to the at least one control member0180, which provides a driving signal, via the conducting wire or the conducting structural, thereby to drive the electro-optic medium layer0140.

When the electro-optic medium layer0140is enabled, the electro-optic medium layer0140would undergo an electrochemical redox reaction and change its energy level to be in a diming state. When an external light passes through the opening of the casing0110and reaches the electro-optic medium layer0140, the external light would be absorbed by the electro-optic medium layer0140which is in the diming state, so that the vehicle electronic rear-view mirror0100is switched to an anti-glare mode. On the other hand, when the electro-optic medium layer0140is disenabled, the electro-optic medium layer0140is transparent. At this time, the external light passing through the opening of the casing0110passes through the electro-optic medium layer0140to be reflected by the reflective layer0190, so that the vehicle electronic rear-view mirror0100is switched to a mirror mode.

More specifically, the first transparent assembly0120has the first incidence surface0122which is away from the second transparent assembly0130. For instance, an external light from the rear vehicles enters the vehicle electronic rear-view mirror0100via the first incidence surface0122, and the vehicle electronic rear-view mirror0100reflects the external light, so that the external light leaves the vehicle electronic rear-view mirror0100via the first incidence surface0122. In addition, eyes of the vehicle driver could receive the external light reflected by the vehicle electronic rear-view mirror0100to know the position of other vehicles behind. Moreover, the reflective layer0190could have the optical properties of partial penetration and partial reflection by selecting a suitable material and design a proper film thickness.

A movable carrier auxiliary system which is a vehicle electronic rear-view mirror0100as an example according to a second structural embodiment of the present invention is illustrated inFIG. 1C.FIG. 1Dis a simplified sectional view ofFIG. 1Cseen from a right shorter lateral side. The difference between the first structural embodiment and the second structural embodiment is that the vehicle electronic rear-view mirror0100according to the second structural embodiment could optionally include an auxiliary reflective layer0192disposed between the reflective layer0190and the first transparent assembly0120. In an embodiment, the auxiliary reflective layer0192could be disposed between the transparent conductive layer0160and the second transparent assembly0130. More specifically, the auxiliary reflective layer0192is disposed between the reflective layer0190and the second transparent assembly0130, and is adapted to assist in adjusting an optical penetration reflection property of the entire vehicle electronic rear-view mirror0100. For example, an external light enters the vehicle electronic rear-view mirror0100via the first incidence surface0122, and the vehicle electronic rear-view mirror0100reflects the external light, so that the external light leaves the vehicle electronic rear-view mirror0100via the first incidence surface0122. In the current structural embodiment, in order to provide the driver an image light with sufficient brightness, a reflectance of the vehicle electronic rear-view mirror0100for reflecting the external light could be more than 35%, and a penetration rate of the vehicle electronic rear-view mirror0100for the image light could be, for example, greater than 15%. In addition, the auxiliary reflective layer0192could also be used as an adhesive layer between the reflective layer0190and the second transparent assembly0130, which could facilitate the reflective layer0190to be attached to the second transparent assembly0130. In the current structural embodiment, the auxiliary reflective layer0192includes at least one material selected from a group consisting of chromium (Cr), titanium (Ti), and molybdenum (Mo), or an alloy thereof, or could also include other types of materials, thereby to adjust the optical penetration reflection property of the entire vehicle electronic rear-view mirror0100. For instance, the material of the auxiliary reflective layer0192could be selected from a group consisting of at least one of chromium, titanium, aluminum, molybdenum, and silver, or an alloy thereof, or could include cerium oxide or a transparent conductive material. Moreover, the material of the auxiliary reflective layer0192could be indium tin oxide or other metal oxides. However, the material of the auxiliary reflective layer is not limited by the materials as exemplified above.

The difference between the first structural embodiment and the third structural embodiment is that the movable carrier auxiliary system100according to the third structural embodiment includes at least one monitor0200disposed on a side of the second transparent assembly0130away from the first transparent assembly0120. For instance, in a structural embodiment, the at least one monitor0200is disposed on the second exit surface0134of the second transparent assembly0130away from the first transparent assembly0120. In addition, the monitor0200is adapted to emit an image light, wherein the image light passes through the vehicle electronic rear-view mirror0100and leaves the vehicle electronic rear-view mirror0100via the first incidence surface0122. Since the reflective layer0190has the optical properties of partial penetration and partial reflection, an image light emitted by the monitor0200could pass through the reflective layer0190, allowing the user to see an internal image displayed by the monitor0200. In the current structural embodiment, a size and an outer contour of the monitor0200are approximately the same as the first transparent assembly0120(i.e., a full screen). In addition, the monitor0200could be a streaming media for providing a driving information or a road condition information to the driver, that is, all visible areas of the vehicle electronic rear-view mirror0100according to the current structural embodiment could simultaneously provide the external light from other vehicles behind and the image light from the monitor0200to the driver, thereby to achieve a good driving assistance performance. Moreover, the size and the outer contour of the monitor0200could be designed to be smaller than the first transparent assembly0120to meet specific requirements, so that only a specific visible area on first transparent assembly0120could observe the image light from the monitor0200. In the current structural embodiment, the monitor0200could be a liquid crystal display (LCD) for example, or could be other types of monitor such as organic light-emitting diode (OLED) monitor. However, the monitor is not a limitation of the present invention.

The difference between the third structural embodiment and the fourth structural embodiment is that the movable carrier auxiliary system100according to the fourth structural embodiment includes at least one video module disposed on a side of the second transparent assembly0130away from the first transparent assembly0120and facing a forward direction of the movable carrier for example, and being electrically coupled to the monitor0200. When an external image of the movable carrier needs to be captured, at least one control member0180could be electrically connected to the video module0300through a first signal transmission line0310and activated, and then an external image signal of the movable carrier captured by the video module0300could be transmitted to the monitor0200via a second signal transmission line0320, thereby to provide an instant driving information or a real-time traffic information to the driver.

In the current structural embodiment, the monitor0200could be a screen with a high dynamic range (HDR), which could show brightness with more obvious light and shade color transition, closer to a real situation seen by the human eye. In order to achieve a condition with a sufficient light compared with the external environment of the movable carrier, the monitor0200could be a screen with a brightness exceeding 1000 nits (most preferable), or with a brightness exceeding 4000 nits (nts)(second preferable), thereby the driver could clearly observe the driving information or the road condition information presented by the monitor0200within the movable carrier.

In the current structural embodiment, there is further a signal input device (not shown) electrically coupled to the displaying device, wherein the signal input device is adapted to send a heterogeneous signal that is not from the optical image capturing system to the display device for numerical or graphical presentation. The signal input device could be a tire pressure detector (TPMS) for example, so that an internal tire pressure of the movable carrier could be detected and instantly converted into a digital signal, wherein the digital signal is transmitted to the display device to be displayed in a numerical or graphical manner, thereby to help the driver to grasp the movable carrier and achieve a warning effect.

In a structural embodiment, the movable carrier auxiliary system includes a plurality of video modules0300(not shown), wherein each of the video modules0300is disposed on different positions of the movable carrier auxiliary system. For instance, if the movable carrier is a vehicle, the video modules0300could be respectively disposed on the left/right rear-view mirrors, on the front/rear bumpers, or between the front windshield and the rear windshield inside of the vehicle, wherein the external image signal captured by each of the video modules0300could be transmitted to the monitor0200, and could be instantly and simultaneously presented to the driver for different viewing directions in a non-overlapping manner or in an image butting manner.

In a structural embodiment, the movable carrier auxiliary system further includes at least one movable detector (not shown) and a plurality of video modules (not shown), wherein each of the video modules is disposed on different positions of the movable carrier auxiliary system (not shown). For instance, if the movable carrier is a vehicle, the video modules could be respectively disposed on the left/right rear-view mirrors, on the front/rear bumpers, or between the front windshield and the rear windshield inside of the vehicle. When the movable carrier is in a state of shutting down the power system and stopping driving, the movable detector starts to continuously detect whether the movable carrier is collided or vibrated. If the movable carrier is bumped or vibrated, the movable detector starts the video modules to instantly record, thereby to help the driver record collision events for on-site restoration and gathers the evidence.

In a structural embodiment, the movable carrier auxiliary system further includes a switch controller and two video modules0300(not shown), wherein one of the video modules0300is disposed on a front position of the movable carrier, and another one thereof is disposed on a rear position of the movable carrier. When the movable carrier is on a reverse mode, the monitor0020could display a rear image of the movable carrier and instantly record the video, thereby assisting the driver to avoid the rear collision event of the movable carrier.

In a structural embodiment, the movable carrier auxiliary system further includes an information communication device (not shown), wherein the information communication device is adapted to communicate with a default contact person or organization, so that when the driver encounters a specific event such as a traffic accident, the driver could notify somebody and seek an assistance through the information communication device to avoid an expansion of personal property damage.

In a structural embodiment, the movable carrier auxiliary system further includes a driving setter and a biological identification device (not shown), wherein the driving setter is electrically connected to the biological identification device. When a specific driver enters the movable carrier and faces the biological identification device, an identification could be performed and the driving setter is started. The driving setter controls the movable carrier according to parameters preset by an individual driver, thereby assisting the driver to quickly complete the corresponding setting of the movable carrier usage habit and effectively control the movable carrier.

Moreover, a maximum diameter of an image-side surface of a lens of the lens group closest to the image plane is denoted by PhiB, and a maximum effective diameter of the image-side surface of the lens of the lens group L closest to the image plane (i.e., the image space) could be also called optical exit pupil, and is denoted by PhiA.

In an embodiment, the lenses of high Abbe number and the lenses of low Abbe number are arranged in an interlaced arrangement that could be helpful for correction of aberration of the optical image capturing module.

An equation of aspheric surface is
z=ch2/[1+[1(k+1)c2h2]0.5]+A4h4+A6h6+A8h8+A10h10+A12h12+A14h14+A16h16+A18h18+A20h20+  (1)

where z is a depression of the aspheric surface; k is conic constant; c is reciprocal of the radius of curvature; and A4, A6, A8, A10, A12, A14, A16, A18, and A20 are high-order aspheric coefficients.

In the optical image capturing module, the lenses could be made of plastic or glass. The plastic lenses may reduce the weight and lower the cost of the optical image capturing module, and the glass lenses may control the thermal effect and enlarge the space for arrangement of the refractive power of the optical image capturing module. In addition, the opposite surfaces (object-side surface and image-side surface) of the first to the seventh lenses could be aspheric that could obtain more control parameters to reduce aberration. The number of aspheric glass lenses could be less than the conventional spherical glass lenses, which is helpful for reduction of the height of the optical image capturing module.

When the lens has a convex surface, which means that the surface is convex around a position, through which the optical axis passes, and when the lens has a concave surface, which means that the surface is concave around a position, through which the optical axis passes.

The optical image capturing module of the present invention could be applied in a dynamic focusing optical image capturing module. It is superior in the correction of aberration and high imaging quality so that it could be allied in lots of fields.

The optical image capturing module of the present invention could further include a driving module to meet different demands, wherein the driving module could be coupled with the lenses to move the lenses. The driving module could be a voice coil motor (VCM), which is used to move the lens for focusing, or could be an optical image stabilization (OIS) component, which is used to lower the possibility of having the problem of image blurring which is caused by subtle movements of the lens while shooting.

To meet different requirements, at least one lens among the first lens to the seventh lens of the optical image capturing module of the present invention could be a light filter, which filters out light of wavelength shorter than 500 nm. Such effect could be achieved by coating on at least one surface of the lens, or by using materials capable of filtering out short waves to make the lens.

To meet different requirements, the image plane of the optical image capturing module in the present invention could be either flat or curved. If the image plane is curved (e.g., a sphere with a radius of curvature), the incidence angle required for focusing light on the image plane could be decreased, which is not only helpful to shorten the length of the optical image capturing module (TTL), but also helpful to increase the relative illuminance.

We provide several optical embodiments in conjunction with the accompanying drawings for the best understanding. In practice, the optical embodiments of the present invention could be applied to other structural embodiments.
