Description

Technical Field

[0001] The present application relates to the technical field of vehicle mirrors, and in particular to a vehicle mirror with a wider field of view and a vehicle. Background Art

[0002] With the continuous development of my country's economy, vehicles have become people's basic means of transportation, which has led to a continuous increase in the number of vehicles year by year. With the substantial increase in the number of vehicles, problems such as road congestion and frequent traffic accidents have emerged.

[0003] Conventional rearview mirrors are important tools that enable drivers to easily observe the vehicle's surroundings, and their visual range is directly related to the driver's perception and judgment of the surrounding road conditions. However, the visual range of current vehicle rearview mirrors is limited, and it is not possible to observe the road conditions more comprehensively.

[0004] Specifically, traditional rearview mirrors are mainly used to observe the road conditions behind, so they can only provide a limited field of view. Especially when the vehicle is driving, the visible range of the rearview mirror is affected by many factors, such as the shape of the vehicle, the height of the driver and the seat position. The limited visible range of the rearview mirror makes it difficult for the driver to fully and accurately grasp the situation around the vehicle during driving, thereby increasing the risk of traffic accidents. Especially in the case of road congestion, the distance between vehicles becomes smaller and the driving speed becomes slower. The driver needs to observe and judge the dynamics of the surrounding vehicles more frequently to avoid collisions. If the visible range of the rearview mirror is limited, it is difficult for the driver to detect and respond to potential dangers in time, which can easily cause traffic accidents.

[0014] In other embodiments, the beam angle adjustment unit is at least two plane mirrors.

[0045] The following will be combined Figures 1 to 12 The vehicle mirror provided in the embodiments of the present application is introduced.

[0046] According to an embodiment of the present application, a vehicle mirror is provided, which is used to be connected to a vehicle body, specifically, connected to a vehicle body portion, and can be used as a left side mirror of the vehicle or a right side mirror of the vehicle. According to the vehicle mirror of the embodiment of the present application, the side view can be expanded, thereby reducing the probability of traffic accidents to a certain extent and ensuring driving safety.

[0047] In the description of the structure and principle shown in the accompanying drawings, the vehicle mirror is described as the left side mirror of the vehicle. It should be noted that the right side mirror of the vehicle is assumed to be symmetrical with the left side mirror of the vehicle by default, so the description is also applicable to the right side mirror of the vehicle. For the sake of brevity, the example of the right side mirror of the vehicle will not be described repeatedly.

[0048] like Figure 1 and Figure 2 As shown, the vehicle mirror comprises a mirror housing 10, a rearview mirror body 20 and a sideview mirror assembly 30. The mirror housing 10 is used to be connected to the body of the vehicle, the mirror housing 10 has a mounting slot 13 opening toward the rear, the rearview mirror body 20 is arranged at the notch of the mounting slot 13, and is used to reflect the scene behind the vehicle mirror to provide the driver with a rear view, and the sideview mirror assembly 30 is used to detect objects located at the side and behind the side of the vehicle mirror.

[0049] According to the first aspect of the present application, Figure 3 As shown, the side-view mirror assembly 30 includes a wide-angle incident lens 31 and an optical reflective element 32. The wide-angle incident lens 31 is arranged on the first side portion 11 of the mirror housing 10, and the wide-angle incident lens 31 serves as the light beam entrance of the side-view mirror assembly 30. The optical reflective element 32 is arranged in the mounting groove 13, wherein the light beam outside the first side portion 11 is incident through the wide-angle incident lens 31 and is reflected by the optical reflective element 32 and then emitted from the second side portion 12, so that the driver can observe the scene on the side and rear of the vehicle, wherein the first side portion 11 and the second side portion 12 are opposite, and the second side portion 12 is located at one end of the mirror housing 10 facing the vehicle body.

[0050] According to the vehicle mirror provided by the embodiment of the present application, when in use, the rearview mirror body 20 can reflect objects located behind the vehicle's driving direction, providing the driver with a rear view. The side mirror assembly 30 can provide the driver with information about objects located on the side and behind the side of the vehicle mirror, providing the driver with a side and behind side view. In this way, the driver's observable field of view during driving can be expanded, and blind spots can be reduced, thereby reducing the probability of traffic accidents to a certain extent and ensuring driving safety.

[0051] In the embodiment of the present application, the mirror housing 10 forms the main structure of the vehicle mirror, which is used to be connected to the body of the vehicle. It can be a shell structure made of plastic, and the interior (the inner wall of the mounting groove 13) is set to black to avoid interfering with various optical elements (for example, the side mirror assembly 30).

[0052] Reference Figure 1 ,exist Figure 1, the general structure of the mirror housing 10 according to the present application is shown in the figure. The notch of the mounting groove 13 of the mirror housing 10 faces the rear side of the vehicle's driving direction. The first notch is located at the first side portion 11 (left side) of the mirror housing 10, located at the end of the mirror housing 10 away from the vehicle body, so as to serve as the light beam entrance of the side-view mirror assembly 30, and can also serve as the installation position of the wide-angle incident lens 31. The second notch is located at the second side portion 12 (right side) of the mirror housing 10, opposite to the first side portion 11, located at the end of the mirror housing 10 facing the vehicle body, and serves as the light beam exit of the side-view mirror assembly 30.

[0053] According to the present application, the first side portion 11 and the second side portion 12 of the mirror housing 10 are respectively formed with gaps at corresponding positions. Furthermore, a light-transmitting plate can be installed at the gap, and the gap can be any suitable shape, such as circular, elliptical or irregular. The light-transmitting plate is a transparent material, such as glass or plastic, which allows the light beam to penetrate while forming a sealed structure inside the mirror housing 10 to prevent dust from entering. The first side portion 11 and the second side portion 12 are connected to each other through the mounting groove 13.

[0054] According to the present application, the optical reflective element 32 is capable of receiving the light beam emitted from the wide-angle incident lens 31. The external light beam is incident on the wide-angle incident lens 31, and after passing through the wide-angle incident lens 31, it is incident on the optical reflective element 32, and then is reflected by the optical reflective element 32 and emitted from the second side portion 12 to enter the driver's eyes. Figure 3 , the light path A of the light beam incident along the optical axis h1 of the wide-angle incident lens 31 is shown, and the light beam incident on the wide-angle incident lens 31 at other angles can also be adjusted by the optical reflective element 32 and then transmitted to the driver's eyes through the second side portion 12. Therefore, the vehicle driver can observe the image of the scene whose light beam can be incident on the wide-angle incident lens 31 through the outgoing light beam of the second side portion 12.

[0055] According to the present application, the rearview mirror body 20 and the side mirror assembly 30 are arranged in one mirror housing 10, which can reduce the number of mirror housings and ensure the compactness and aesthetics of the vehicle mirror. The rearview mirror body 20 can be arranged as a reflector, for example, a convex reflector. As an example, the optical path of the side mirror assembly 30 is located behind the rearview mirror body 20 and has a certain interval, so that the installation and optical effects of the rearview mirror body 20 and the side mirror assembly 30 do not interfere with each other.

[0056] According to the present application, the side mirror assembly 30 is a wide-angle side mirror assembly, including a wide-angle incident lens 31 and an optical reflective element 32. The wide-angle incident lens 31 is arranged in the first notch, has a wide field of view, and is used to capture the light beams of the side and the objects behind the side of the vehicle. After the light beams of the side and the objects behind the side of the vehicle mirror are incident on the wide-angle incident lens 31, the parallel light beams in the outgoing light beams are incident on the optical reflective element 32. The optical reflective element 32 is arranged in the mounting groove 13 and is located in front of the rearview mirror body 20 along the driving direction of the vehicle. It can receive the parallel outgoing light beams transmitted by the wide-angle incident lens 31 and further process and image them. The processing may include additional refraction, reflection or correction to ensure that the driver can see a clear image. The processed light beam will be emitted from the second notch and directly enter the driver's field of view. Through the combination of the wide-angle incident lens 31 and the optical reflective element 32, the driver's side and side rear field of view can be expanded, the blind spot can be reduced, and the driving safety can be improved.

[0057] In these embodiments, the wide-angle incident lens 31 can receive light beams from a wider area at the corresponding position of the side or rear of the vehicle, so that the vehicle mirror can cover a wider field of view, which helps the driver to more comprehensively understand the environment around the vehicle and improve driving safety. In addition, by converting the light beams from the side and rear of the vehicle into parallel outgoing light beams, the wide-angle incident lens 31 can reduce the distortion and distortion of the light beams during transmission, thereby improving the clarity and contrast of the imaging.

[0058] According to the present application, the wide-angle incident lens 31 is a concave lens. In some embodiments, a concave lens, such as a double concave lens, a plano-concave lens, and a concave-convex lens, can obtain an expanded field of view in the corresponding direction by controlling the installation direction of the corresponding lens, thereby improving driving safety and convenience.

[0059] In some embodiments, the wide-angle incident lens 31 is a meniscus concave lens, such as Figure 6As shown, the meniscus concave lens includes a first surface 311 (convex surface) and a second surface 312 (concave surface) opposite to each other in the thickness direction. The first surface 311 is arranged to face away from the mounting groove 13, that is, to face away from the inside of the mirror housing or to face the outside of the vehicle, and the second surface 312 is arranged to face the mounting groove 13, that is, to face the inside of the mirror housing. And the curvature of the first surface 311 is less than the curvature of the second surface 312. It can be understood that the curvature of the second surface 312 is greater, while the first surface 311 is relatively flat. According to the present application, the meniscus concave lens can be a spherical surface, a cylindrical surface or a curved surface (non-standard spherical surface). The curved meniscus lens is similar to the spherical meniscus lens in appearance, except that its curved surface is not a part of a standard circle. Specifically, when the light beams of the objects located at the side and the back of the side of the vehicle mirror enter the meniscus concave lens, they will be refracted by the meniscus concave lens and a wide-angle image will be obtained. The light beam refracted by the meniscus concave lens will enter the optical reflective element 32 installed in the mounting groove 13. Through the combination of the meniscus lens and the optical reflective element 32 , the driver can see the side, the rear side and a wider field of view of the rear of the vehicle, thereby improving driving safety.

[0060] In some other embodiments, the wide-angle incident lens 31 is a wide-angle lens group, which includes a plurality of lenses, and the optical axes of the lenses are coaxially arranged. Figure 7 As shown, the wide-angle incident lens 31 is a lens group including a meniscus concave lens and a lens of another type, and the optical axes of the two lenses are coaxially arranged.

[0061] In these embodiments, the wide-angle incident lens 31 is a lens group, and the optical axes of the multiple lenses are coaxially arranged, which can ensure that the light beam maintains a consistent propagation path when passing through the lens group, thereby avoiding light beam deviation or distortion, and improving imaging quality and clarity. When the wide-angle incident lens 31 is a combination of a meniscus concave lens and other lenses, a synergistic effect can be generated, image distortion can be reduced, imaging quality and clarity can be further improved, and the optical performance of the wide-angle incident lens 31 can be enhanced.

[0062] According to the present application, the orientation of the wide-angle incident lens 31 will affect the imaging effect of the side-view mirror assembly 30. By adjusting the orientation of the wide-angle incident lens 31, a wide-angle field of view in the corresponding direction can be obtained. In some embodiments, the wide-angle incident lens 31 is adjustably arranged in the first side portion 11, and the first side portion 11 is provided with a notch, and the wide-angle incident lens 31 can be installed in the notch, or a light-transmitting plate is arranged in the notch, and the wide-angle incident lens 31 is installed on the inner side of the light-transmitting plate.

[0063] As an example, the wide-angle incident lens 31 can be adjustably arranged at the first side portion 11 through a rotating body, wherein the rotating body is arranged on the side wall of the notch or the light-transmitting plate. The wide-angle incident lens 31 is mounted on the rotating body, so that the orientation angle of the wide-angle incident lens 31 is adjustable to meet the actual needs of different drivers and improve driving safety and comfort. Specifically, the orientation angle of the wide-angle incident lens 31 can be adjusted within the range of 3°-15°, and the rotating body can be a ball joint and a locking portion, wherein one end of the ball joint is fixed on the side wall of the second notch, and the other end is connected to the fixed mounting bracket of the wide-angle incident lens 31. The ball joint allows the wide-angle incident lens 31 to rotate freely in multiple directions to adapt to different orientation angles, and the locking portion can fix the lens at a desired angle, which can ensure that the lens maintains a stable orientation during vehicle driving and will not be offset due to vibration or other factors. It should be noted that, in this embodiment, when the wide-angle incident lens 31 rotates at a certain fixed angle, the optical reflective element 32 can move along the optical axis h1 of the wide-angle incident lens 31 .

[0064] In these embodiments, based on the different heights, sitting postures and vision requirements of different drivers, a vision setting suitable for the corresponding driver can be found by adjusting the orientation angle of the wide-angle incident lens 31. In addition, if the use environment of the vehicle changes, for example, switching from a city road to a highway, the driver can also adjust the orientation of the wide-angle incident lens 31 at any time to adapt to different driving requirements.

[0065] According to the present application, the optical reflective element 32 is a reflector to achieve a specific imaging effect and field of view. For example, the reflector is a plane reflector or a total reflection prism, which is used to reflect the light beam entering the mounting groove 13 through the wide-angle incident lens 31 to the second notch at a predetermined angle and emit from the second notch.

[0066] The total reflection prism can realize the angle deflection of the outgoing light beam of the wide-angle incident lens 31 by 90°, and then guide them to the second notch so that the driver can observe. The plane reflector can realize the angle deflection of the outgoing light beam of the wide-angle incident lens 31 by more than 0 and less than 180 degrees, and then guide them to the second notch so that the driver can observe. In addition, as other examples of the present application, the optical reflection element 32 can be a semi-pentagonal prism, and the angle between the incident light beam and the outgoing light beam of the semi-pentagonal prism is 45°, which can realize the angle deflection of the outgoing light beam of the wide-angle incident lens 31 by 45°, and then guide them to the second notch so that the driver can observe. It should be noted that according to the semi-pentagonal prism and the total reflection prism of the present application, only the fixed angle can be changed because it is necessary to ensure that the incident light beam and the outgoing light beam are perpendicular to the surface on the corresponding optical element to avoid refraction on the surface so that the imaging becomes blurred or distorted.

[0067] In the wide-angle side mirror assembly, by using a half-pentagonal prism, the propagation path of the light beam can be further adjusted and optimized to meet the driver's field of vision while ensuring the size of the vehicle mirror. It should be noted that whether the optical reflective element 32 uses a total reflection prism or a half-pentagonal prism is mainly selected based on the lateral distance between the vehicle mirror and the driver. If the end of the vehicle mirror close to the vehicle body is relatively close to the lateral distance of the driver (for example, 8cm-15cm), the deflection angle of the incident light beam of the optical reflective element 32 is required to be approximately 90°. In this case, a total reflection prism can be selected as the optical reflective element 32. If the end of the vehicle's viewfinder close to the vehicle body is relatively far away from the driver's lateral distance (for example, 15cm-25cm), in this case, the deflection angle of the incident light beam of the optical reflective element 32 is required to be approximately 45°. At this time, the total reflection prism cannot meet the requirement, and a semi-pentagonal prism is required to replace the total reflection prism to achieve a light path change of approximately 45°; the optical reflective element 32 uses a plane mirror, and the deflectable angle of the incident light beam of the optical reflective element 32 is in a range, which is generally set to 40° to 90° here.

[0068] Hereinafter, a side view mirror assembly 30 according to the first embodiment of the present application will be described by taking a total reflection prism as an example.

[0069] like Figure 3 , Figure 8 and Fig. 9 As shown, the light beam emitted from the optical axis h1 of the wide-angle incident lens 31 (i.e., the central axis of the wide-angle incident lens 31) is perpendicular to a right-angle surface AB of the total reflection prism and passes through the geometric center of a right-angle surface AB. The light beam emitted from the optical axis h1 passes through the total reflection prism, and the output light beam h2 coincides with the line connecting the hypotenuse surface AC and the geometric center of another right-angle surface BC.

[0070] Specifically, the total reflection prism is installed inside the mirror housing 10, and the optical axis h1 of the wide-angle incident lens 31 is perpendicular to the right-angled surface AB of the total reflection prism and passes through the geometric center of the right-angled surface AB. The angle between the right-angled surface BC and the right-angled surface AB is 90°. At this time, the normal angle between the optical axis h1 of the wide-angle incident lens 31 and the geometric center of the hypotenuse surface AC of the total reflection prism is 45°. The line connecting the geometric center of the hypotenuse surface AC of the total reflection prism and the geometric center of the right-angled surface BC coincides with the outgoing light beam h2 after the light beam emitted from the optical axis h1 passes through the total reflection prism. In a preferred embodiment, the outgoing light beam h2 after the light beam emitted from the optical axis h1 passes through the total reflection prism passes through the geometric center of the second notch. In this case, it can be ensured that the light beam emitted from the total reflection prism can enter the driver's field of vision as much as possible. Figure 3 As shown, optical path A shows a partial optical path of the side view mirror assembly 30 .

[0071] As an example, the lengths of the sides of the bottom surface of the total reflection prism are d1=d2=d4=4cm-6cm, d3 can be 7cm-8cm, and Specifically, d1=d2=d4=5cm,

[0072] In these embodiments, the optical reflection element 32 is located on the optical axis h1 of the wide-angle incident lens 31, and a right-angled surface of the total reflection prism is perpendicular to the optical axis h1, and h1 passes through the geometric center of the right-angled surface. When the light beam emitted from the optical axis h1 of the wide-angle incident lens 31 is incident perpendicular to the right-angled surface AB of the total reflection prism, the light beam is reflected by the hypotenuse surface AC of the total reflection prism and emitted from the other right-angled surface BC of the total reflection prism. The path of the outgoing light beam h2 from the right-angled surface BC coincides with the line connecting the hypotenuse surface AC of the total reflection prism and the geometric center of the other right-angled surface BC, and the outgoing light beam h2 will eventually be emitted from the second notch. By observing these light beams, the driver can see the traffic conditions on the side and rear of the vehicle, thereby enhancing driving safety.

[0073] In some embodiments, the distance L3 between the center point of the wide-angle incident lens 31 and the center point of the optical reflective element 32 (reference Figure 3 ) is 2cm-15cm.

[0074] According to the vehicle mirror of the present application, taking the vehicle mirror as the left mirror of the vehicle as an example, when the distance L3 between the center point of the wide-angle incident lens 31 and the center point of the optical reflective element 32 is 2 cm, the human eye can see the 90°-170° viewing angle range on the left side of the wide-angle incident lens 31 through the outgoing light beam of the optical reflective element 32. When the distance L3 between the center point of the wide-angle incident lens 31 and the center point of the optical reflective element 32 is 15 cm, as the distance between the two increases, the viewing angle range that can be seen will become smaller. At this time, the human eye can see through the optical reflective element 32 that the viewing angle range on the left side of the wide-angle incident lens 31 will be reduced. As an example, the reduced viewing angle is 90°-150°. It can be seen that the distance L3 between the center point of the wide-angle incident lens 31 and the center point of the optical reflective element 32 can affect the overall visual range of the side mirror assembly to a certain extent.

[0075] In some embodiments, the wide-angle incident lens 31 is a meniscus concave lens, and the focal length of the wide-angle incident lens 31 is negative 25 mm-35 mm, and the diameter is 4 cm-8 cm.

[0076] In these embodiments, the wide-angle incident lens 31 has a preset focal length and diameter. Such a wide-angle incident lens 31 has a certain luminous flux and resolution for light, can expand the driver's visual field, and can ensure the clarity of objects seen by the driver, thereby ensuring the imaging quality.

[0077] exist Figure 3 In the example shown, the plane where the incident light beam coinciding with the optical axis h1 of the wide-angle incident lens 31 and the outgoing light beam h2 processed by the optical reflective element 32 is located is defined as the reference plane M1, and the mounting reference plane of the rearview mirror body 20 is defined as the reference plane M2, and it is assumed that the reference plane M1 is perpendicular or approximately perpendicular to the reference plane M2, and the reference plane M2 is perpendicular to the bottom surface T1 of the total reflection prism (i.e., the optical reflective element 32). In this case, the angle between the projection of the optical axis h1 of the wide-angle incident lens 31 in the reference plane M2 and the optical axis h1 is β, and the distance between the optical reflective element 32 and the reference plane M2 is L1.

[0078] When the size and position of the rearview mirror body 20 are determined, the size of the vehicle mirror mainly depends on the thickness of the vehicle mirror in the front-to-back direction, and the thickness in the front-to-back direction depends on the position of the optical reflective element 32 relative to the rearview mirror body 20. The closer the optical reflective element 32 is to the rearview mirror body 20, the thinner the vehicle mirror can be. In other words, Figure 3 As shown, the smaller the distance L1 between the optical reflective element 32 and the reference surface M2 is, the more conducive it is to reduce the thickness of the vehicle mirror. In other words, when the distance L3 between the wide-angle incident lens 31 and the optical reflective element 32 is roughly determined, the smaller the angle β is, the smaller L1 is.

[0079] In order to further reduce the thickness of the vehicle mirror, the present application provides a vehicle mirror according to a second embodiment. Figure 4 As shown, the side mirror assembly 30 further includes a beam angle adjustment portion 33, which is disposed between the wide-angle incident lens 31 and the optical reflective element 32 and is used to adjust the angle of the light beam incident on the optical reflective element 32, thereby adjusting the position of the optical reflective element 32. By minimizing the thickness of the vehicle mirror in the direction of vehicle travel, the rearview mirror can be made thinner and lighter.

[0080] Hereinafter, the second embodiment according to the present application will be specifically described. The difference from the first embodiment of the present application is that, in the second embodiment, a beam angle adjustment unit 33 is further provided between the wide-angle incident lens 31 and the optical reflective element 32. It should be noted that in these embodiments, the differences from the aforementioned embodiments (for example, the beam angle adjustment unit 33) will be mainly described, and the parts that are the same as those in the first embodiment, such as the rearview mirror body 20 and the optical reflective element 32, will not be described in detail here.

[0081] According to other embodiments of the present application, the vehicle mirror includes a beam angle adjustment portion 33, which may be an optical angle adjuster or a beam redirector, for changing the propagation direction of the light beam, thereby adjusting the incident angle of the light entering the subsequent optical reflective element 32. Specifically, the beam angle adjustment portion 33 can make the light beam emitted from the wide-angle incident lens 31 offset toward the rearview mirror body 20 relative to the optical axis h1 of the wide-angle incident lens 31 after passing through the beam angle adjustment portion 33, so that the optical reflective element 32 is disposed between the optical axis h1 and the rearview mirror body 20, so as to reduce the size of the vehicle mirror.

[0082] In these embodiments, by providing a beam angle adjustment portion 33 between the wide-angle incident lens 31 and the optical reflective element 32, it is possible to reduce the thickness of the vehicle mirror in the direction of vehicle travel without sacrificing the field of view as much as possible, reduce the wind resistance and aerodynamic noise of the vehicle mirror, improve the field of view and improve driving safety, thereby enhancing the driving experience.

[0083] As an example, the beam angle adjustment unit 33 is a half pentagonal prism. The half pentagonal prism is set between the wide-angle incident lens 31 and the optical reflective element 32 as the beam angle adjustment unit 33, which can change the propagation direction of the light beam and adjust the beam angle, thereby changing the relative position of the wide-angle incident lens 31 and the optical reflective element 32 in the vehicle's driving direction, effectively controlling the incident angle of light entering the subsequent optical reflective element 32, and minimizing the size of the vehicle's mirror while ensuring that the light path in the side-view mirror assembly 30 is carried out in a specific direction. In addition, according to the optical characteristics of the half pentagonal prism, the loss of the light beam during the propagation process can be effectively reduced, and the utilization rate of the light beam can be improved, so that the rearview mirror can maintain a clear and bright field of view at night or in low light environments.

[0084] According to the present application, the lateral dimension of the mirror housing may be 10 cm-18 cm, the height dimension may be 8 cm-10 cm, and the thickness dimension along the vehicle travel direction may be 5 cm-8 cm.

[0085] According to the present application, the beam angle adjustment unit 33 has multiple optional installation positions, so that the designer can specifically define its position according to actual requirements. In some embodiments, the beam angle adjustment unit 33 is a semi-pentagonal prism, which can be as follows Figure 4 As shown, it is set at a position corresponding to the optical axis h1 of the wide-angle incident lens 31, or as shown Figure 5 As shown, it is arranged at a position above the optical axis h1 of the wide-angle incident lens 31.

[0086] If you need to get more side vision, you can Figure 4As shown in FIG. 1 , the half-pentagonal prism is arranged near the optical axis to obtain more light beams in the central area of ​​the optical reflective element 32. If it is desired to further expand the field of view of the side lower part, it can be as follows Figure 5 As shown, the semi-pentagonal prism is arranged above the optical axis of the wide-angle incident lens 31, so that more light beams at the lower side can enter the optical reflective element 32. By adjusting the position of the beam angle adjustment part 33, the field of view can be controlled while reducing the thickness of the rearview mirror. This not only helps to improve driving safety, but also enhances the driving experience of the driver.

[0087] Hereinafter, the side view mirror assembly 30 according to the second embodiment of the present application will be specifically described by taking a total reflection prism (isosceles right-angle prism) as the optical reflection element 32 and a half-pentagonal prism as the beam angle adjustment part 33 as an example.

[0088] According to the present application, the side-view mirror assembly 30 is composed of a wide-angle incident lens 31, a semi-pentagonal prism and a total reflection prism. Through the coordinated work of the wide-angle incident lens 31, the semi-pentagonal prism and the total reflection prism, the side-view mirror assembly 30 can expand the driver's field of view, enabling him to observe a wider traffic environment, thereby improving the driver's safety and comfort during driving.

[0089] Reference Fig.10 and Fig.11 , define the various faces and partial angles of the half pentagonal prism, where H1 is the large end face of the half pentagonal prism, H2 is the oblique short waist face of the half pentagonal prism, H3 is the top face of the half pentagonal prism, H4 is the small end face of the half pentagonal prism, H5 is the oblique long waist face of the half pentagonal prism, θ1 is 22.5°, and θ2 is 45°.

[0090] Fig.11 Figure 2 shows the path of a light beam in a half-penta prism. Fig.11 The incident light beam is vertically incident from the large end face H1 of the semi-pentagonal prism, and after the first reflection from the oblique waist face H5, it is incident on the oblique short waist face H2. After the second reflection from the oblique short waist face H2, it is emitted from the oblique long waist face H5 of the semi-pentagonal prism. It should be noted that in the embodiment of the present application, the outer surface of the oblique short waist face H2 is coated with a reflective coating to better reflect the light beam. The outer surface of the oblique long waist face H5 does not need to be coated with a reflective coating to achieve almost 100% reflection of the light beam. This characteristic is related to the critical angle of the optical element. As long as the light beam is emitted from the optically dense medium (i.e., glass) to the optically sparse medium (i.e., air), when the angle between the incident light beam and the normal of the reflecting surface is greater than a certain angle, the maximum angle for glass is 42°, and the incident angle of the outgoing light beam of the wide-angle incident lens 31 to the oblique long waist face H5 is greater than 42°, forming total reflection. Therefore, although the oblique long waist face H5 does not have a reflective coating, the light beam is also geometrically 100% reflected.

[0091] like Figure 4and Fig.10 As shown, the optical axis h1 of the wide-angle incident lens 31 is perpendicular to the large end surface H1 of the semi-pentagonal prism and passes through the geometric center of the large end surface H1. The outgoing light beam coinciding with the optical axis h1 of the wide-angle incident lens 31, after being reflected twice by the semi-pentagonal prism, is incident perpendicularly to the right-angled surface AB of the total reflection prism, passes through the geometric center of the right-angled surface AB of the total reflection prism, and then is emitted through the right-angled surface BC of the total reflection prism, and finally is emitted through the geometric center of the second notch of the mirror housing 10, wherein the bottom surface T1 of the total reflection prism is approximately perpendicular to the reference surface M2. After adjusting the angle of the mirror housing 10, the outgoing light beam of the wide-angle incident lens 31 is reflected by the semi-pentagonal prism and the total reflection prism, and then enters the driver's eyes at a suitable angle, so that the vehicle driver can observe the scenery on the side of the vehicle's driving direction. Figure 4 2 shows a traveling optical path B of a light beam incident along the optical axis h1 of the wide-angle incident lens 31 .

[0092] like Figure 4 As shown, the semi-pentagonal prism receives the outgoing light beam from the wide-angle incident lens 31 and changes its optical path so that the optical path is deflected by an angle α relative to the optical axis h1 toward the reference plane M2. Accordingly, in order to receive the incident light beam, the total reflection prism needs to be offset toward the rearview mirror body 20, closer to the reference plane M2. Figure 3 In the case where the semi-pentagonal prism is not provided, this arrangement can shorten the vertical distance L1 between the total reflection prism and the reference surface M2 to L2, thereby reducing the space required for installing the total reflection prism and reducing the volume of the vehicle mirror. As an example, L1 can be 5cm-6cm, and L2 can be 2cm-4cm.

[0093] It should be noted that in Figure 4 In the installation mode of the side view mirror assembly 30 shown, the half-penta prism is easy to receive the light beam near the optical axis of the wide-angle incident lens 31. Figure 5 In the example shown, the half-penta prism is disposed above the optical axis h1 of the wide-angle incident lens 31 so as to receive the light beam incident from the lower left of the vehicle. Figure 5 As shown, the travel route of the light beam incident from the lower left of the vehicle is represented by light path C. In this case, the light beam at the lower left of the vehicle enters the driver's field of vision more.

[0094] According to an embodiment of the present application, the setting position (e.g., height, angle) of the beam angle adjustment unit 33 is adjustable, so that the user can select according to the actual situation to obtain the situation of the scenery in the area of ​​interest. In a preferred embodiment, the semi-pentagonal prism is adjustably arranged in the mounting groove 13, so that the user can adjust the relative position of the semi-pentagonal prism according to the actual situation.

[0095] like Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, the light beam emitted from the optical axis h1 of the wide-angle incident lens 31 (i.e., the central axis of the wide-angle incident lens 31) is perpendicular to a right-angle surface AB of the total reflection prism after being adjusted by a semi-pentagonal prism, and passes through the geometric center of a right-angle surface AB. The light beam emitted from the optical axis h1 passes through the total reflection prism, and the output light beam h2 coincides with the line connecting the geometric centers of the hypotenuse surface AC and the other right-angle surface BC.

[0096] Specifically, the total reflection prism is installed inside the mirror housing 10. The optical axis h1 of the wide-angle incident lens 31 is perpendicular to the right-angled surface AB of the total reflection prism after being transformed by the semi-pentagonal prism and passes through the geometric center of the right-angled surface AB. The angle between the right-angled surface BC and the right-angled surface AB is 90 degrees. The bottom surface T1 of the total reflection prism is perpendicular to the reference surface M2. At this time, the normal angle between the optical axis h1 of the wide-angle incident lens 31 and the geometric center of the hypotenuse surface AC of the total reflection prism is 45°. The line connecting the geometric center of the hypotenuse surface AC of the total reflection prism and the geometric center of the right-angled surface BC coincides with the outgoing light beam h2 emitted from the optical axis h1 after passing through the total reflection prism. h1 and h2 form the reference surface M1. In a preferred embodiment, the second notch is a symmetrical pattern. The outgoing light beam h2 emitted from the optical axis h1 after passing through the total reflection prism passes through the geometric center of the second notch. In this case, it can be ensured that all light beams emitted from the total reflection prism can enter the driver's field of vision. Figure 4 and Figure 5 As shown, the optical path diagram B and the optical path diagram C roughly show the partial optical path of the side view mirror assembly 30.

[0097] As an example, the lengths of the sides of the bottom surface of the total reflection prism are d1=d2=d4=4cm-6cm, d3 is 7cm-8cm, and Specifically, d1=d2=d4=5cm,

[0098] In these embodiments, when the light beam emitted from the optical axis h1 of the wide-angle incident lens 31 is adjusted by the semi-pentagonal prism and incident perpendicularly to the right-angled surface of the total reflection prism, the light beam will not be refracted on the right-angled surface AB, but will maintain its original direction to enter the interior of the total reflection prism. Subsequently, the light beam is incident on the hypotenuse surface AC of the total reflection prism, and after being reflected by the hypotenuse surface AC, it is emitted from the other right-angled surface BC of the total reflection prism. The path of the outgoing light beam h2 from the right-angled surface BC coincides with the line connecting the geometric centers of the hypotenuse surface AC of the total reflection prism and the other right-angled surface BC, and the outgoing light beam h2 will eventually enter the driver's eyes from the second notch. By observing these light beams, the driver can see the traffic conditions on the side and rear of the side of the vehicle, thereby enhancing driving safety.

[0099] According to the vehicle mirror of the third embodiment of the present application, at least two plane mirrors are arranged between the wide-angle incident lens 31 and the optical reflective element 32. The plane mirrors are used to adjust the travel path of the light beam so that the optical reflective element 32 is deflected toward the rearview mirror body 20 relative to the optical axis h1, thereby reducing the thickness dimension of the vehicle mirror. Here, the thickness dimension is the dimension along the driving direction of the vehicle.

[0100] Fig.12 is a schematic diagram of the structure of a vehicle mirror according to the third embodiment of the present application. Fig.12 As shown, two plane reflectors are arranged between the wide-angle incident lens 31 and the optical reflective element 32. The reflective surfaces of the two plane mirrors are opposite to each other, and there is a predetermined interval between them. The external light beam is incident through the wide-angle incident lens 31 and reflected by one plane mirror, then enters another plane reflector to adjust the angle and enters the optical reflective element 32. Fig.12 2 shows a traveling optical path D of a light beam incident along the optical axis h1 of the wide-angle incident lens 31 .

[0101] In these embodiments, two plane reflectors are used to adjust the path of the light beam, which is more flexible than other methods. In addition, the wide-angle incident lens 31, the optical reflective element 32 and the plane reflector are combined to form a side mirror assembly, which can expand the driver's field of view and ensure the driver's driving safety while reducing the thickness of the vehicle mirror.

[0102] In some embodiments, the distance L3 between the center point of the wide-angle incident lens 31 and the center point of the optical reflective element 32 (reference Figure 3 ) is 2cm-15cm.

[0103] According to the vehicle mirror of the present application, taking the vehicle mirror as the left mirror of the vehicle as an example, when the distance L3 between the center point of the wide-angle incident lens 31 and the center point of the optical reflective element 32 is 2 cm, the human eye can see the 90°-170° viewing angle range on the left side of the wide-angle incident lens 31 through the outgoing light beam of the optical reflective element 32. When the distance L3 between the center point of the wide-angle incident lens 31 and the center point of the optical reflective element 32 is 15 cm, as the distance between the two increases, the viewing angle range that can be seen will become smaller. At this time, the human eye can see through the optical reflective element 32 that the viewing angle range on the left side of the wide-angle incident lens 31 will be reduced. As an example, the reduced viewing angle is 70°-150°. It can be seen that the distance L3 between the center point of the wide-angle incident lens 31 and the center point of the optical reflective element 32 can determine the overall visual range of the side mirror assembly to a certain extent. In addition, the appropriate distance L3 helps to maintain the clarity and resolution of the imaging.

[0104] In some embodiments, the wide-angle incident lens 31 is a meniscus concave lens, and the focal length of the wide-angle incident lens 31 is negative 25 mm-35 mm, and the diameter is 4 cm-8 cm.

[0105] In these embodiments, the wide-angle incident lens 31 has a preset focal length and diameter. Such a wide-angle incident lens 31 has a certain luminous flux and resolution for light, can expand the driver's visual field, and can ensure the clarity of objects seen by the driver, thereby ensuring the imaging quality.

[0106] In these embodiments, a beam angle adjustment portion is provided between the wide-angle incident lens 31 and the optical reflective element 32, so that the optical reflective element 32 is provided closer to the rearview mirror body 20, thereby reducing the overall size of the mirror assembly along the direction of vehicle travel, thereby ensuring the aesthetics and compactness of the vehicle mirror.

[0107] In some embodiments, the vertical distance between the lower edge of the wide-angle incident lens 31 and the reference plane M2 is 1 cm-3 cm. In this way, the outgoing light beam of the wide-angle incident lens 31 is not blocked by the rearview mirror body 20 and its mounting components, which can ensure that the side-view mirror assembly 30 has good optical properties. At the same time, it also meets the installation requirements in the vehicle mirror, thereby improving the overall quality and reliability of the vehicle mirror.

[0108] It should be noted that the optical effects of the rearview mirror body 20 and the side mirror assembly 30 do not interfere with each other. The beam angle adjustment unit 33 can adjust the angle of the light beam from the wide-angle incident lens 31, and the optical reflective element 32 can receive the light beam adjusted by the beam angle adjustment unit 33, so that the vehicle driver can observe the image formed by the outgoing light beam of the wide-angle incident lens 31 through the outgoing light beam of the optical reflective element 32.

[0109] In some embodiments, the viewing angle of the wide-angle incident lens 31 is in the range of 90°-170°. The driver of the vehicle with the vehicle mirror of the wide-angle incident lens 31 can observe a wider area, including traffic conditions on the side and rear of the side, thereby improving driving safety.

[0110] According to the embodiment of the present application, the side-view mirror assembly 30 can be set as a module, and the installation position and angle of the entire module relative to the mirror housing 10 are adjustable, allowing the driver to adjust according to his actual situation and the area of ​​scenery he wants to see. As some examples, the various components of the side-view mirror assembly 30 (wide-angle incident lens 31, optical reflective element 32) are jointly arranged on an adjustable plate, and the side-view mirror assembly 30 can be tilted toward the rearview mirror body 20 as a whole, so that the visual range of the side-view mirror assembly 30 is deflected toward the rearview mirror body 20 as a whole by a preset angle, so that the visual range of the side-view mirror assembly 30 is close to the visual range of the rearview mirror body 20, reducing the blind spot, or even eliminating the blind spot.

[0111] In addition, the rearview mirror body 20 can also be set as an adjustable structure. For example, the rearview mirror body 20 is rotatably connected to the mirror housing 10. As an example, Figure 3 As shown, a rotating part 40 is provided in the mounting groove 13 of the mirror housing 10, and the rearview mirror body 20 is mounted on the rotating part 40 and can rotate relative to the mirror housing 10. As an example, a mounting frame is provided at a position close to the notch of the mounting groove 13, and the rotating part 40 is provided on the mounting frame. Among them, the mounting frame has a predetermined distance from the notch of the mounting groove 13, as an example, the predetermined distance can be 0.5cm-1.5cm, the rotating part 40 is a ball head rotating part, and the length of the ball head rotating part is less than the predetermined distance, as an example, the length of the ball head rotating part is 0.3cm-1.0cm, and by mounting the rearview mirror body 20 on the rotating part 40, the rearview mirror body 20 can be allowed to adjust the angle in the up, down, left and right directions. As an example, the adjustable angle is 3°-15°.

[0112] In these embodiments, when in use, the driver can adjust the angle of the rearview mirror body 20 to change the reflection direction of the rearview mirror body 20 to adapt to different observation needs or viewing angles of the driver.

[0113] According to a second aspect of the present application, a vehicle is provided, wherein the vehicle comprises a vehicle body and a vehicle mirror provided according to each of the above embodiments, wherein the vehicle mirror and the vehicle body are rotatably connected.

[0114] In some embodiments, the vehicle further includes a vehicle mirror bracket 100 connected between the vehicle mirror and the vehicle body, and the vehicle mirror and the vehicle body are rotatably connected through the vehicle mirror bracket 100 .

[0115] In these embodiments, the vehicle mirror and the vehicle body are rotatably connected via the vehicle mirror bracket, and the structure is simple.

[0116] In some embodiments, the vehicle further includes a control system connected to the vehicle mirror bracket for adjusting a deflection angle of the vehicle mirror.

[0117] As an example, the control system is connected to the mirror bracket by electronic or mechanical means. In some embodiments, the control system drives the bracket to rotate by sending instructions, thereby adjusting the mirror angle. Specifically, the control system first obtains the driver's input information through a sensor. After receiving the sensor input, the control system will perform corresponding processing and analysis, and make a decision based on a preset algorithm or logic. For example, when the driver turns the knob, the control system will calculate the mirror angle that needs to be adjusted. The control system converts the decision instruction into a control signal through an output interface circuit, driving an actuator (e.g., a motor) to drive the mirror bracket to rotate.

[0118] In these embodiments, by connecting the control system to the vehicle mirror bracket to adjust the deflection angle of the vehicle mirror, the driver can easily adjust the angle of the vehicle mirror to obtain the best field of view and driving experience. At the same time, the control system can also automatically adjust according to the driving state of the vehicle to improve driving safety and convenience.

[0119] Although the embodiments of the present application have been described in detail above, those skilled in the art may make various modifications and variations to the embodiments of the present application without departing from the spirit and scope of the present application. However, it should be understood that, in the opinion of those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present application defined by the claims.
