[0035] Example 1
[0036] This embodiment provides a specific implementation of an embedded real-image instrument, including a HUD imaging system and a lifting mechanism. The image source device and the reflector assembly are both mounted on the drive end of the lifting mechanism. The lifting mechanism drives the image source device and the reflector assembly to move up and down to adjust the height of the instrument's real image, adapting to different drivers' viewing angles, accommodating more scenarios, and improving the driver's driving experience. Figure 1 and Figure 2 As shown, the HUD imaging system includes an image source device 1, a reflector assembly, and a lifting mechanism 8. The image source device 1 emits a light beam carrying vehicle instrument image information. The reflector assembly folds the light beam emitted by the image source device 1 and forms a real image of the instrument on the opposite side of the eye box 5. The real image of the instrument is located inside the vehicle dashboard 6. The real image of the instrument can enter the eye box 5 through the reflector assembly for easy viewing by the driver. At the same time, only the image source device 1 and the reflector assembly are installed inside the dashboard 6. The system has fewer parts, a smaller size, and occupies less space. In the event of an accident, it can, to a certain extent, prevent the dashboard from causing secondary injury to the driver.
[0037] Furthermore, the instrument image is located inside the vehicle dashboard, and the downward viewing angle of the instrument image is higher than that of existing instruments. That is, the imaging position height of the instrument image formed by the embedded real image instrument provided in this application is higher than the height of the traditional dashboard display image, making it easier for the driver to observe.
[0038] In this embodiment, the reflector assembly includes a first reflector element 2 and a second reflector element 3. The image source device 1 emits a light beam carrying vehicle instrument information, which is reflected by the first reflector element 2 onto the second reflector element 3, and then reflected again by the second reflector element 3 to the position of the eye box 5. The light beam carrying vehicle instrument information emitted by the image source device 1 is reflected twice by the first reflector element 2 and the second reflector element 3, resulting in optical path folding and forming a real image of the instrument for the driver to view.
[0039] Furthermore, in this embodiment, the lifting mechanism 8 includes a first lifting mechanism 81 and a second lifting mechanism 82. The first lifting mechanism 81 is used to drive the image source device to move up and down, and the second lifting mechanism 82 is used to drive the reflector assembly to move up and down. By adjusting the height between the image source device and the reflector assembly through the first lifting mechanism 81 and the second lifting mechanism 82, the height position of the instrument's real image can be adjusted. At the same time, the first lifting mechanism 81 and the second lifting mechanism 82 can also adjust the height of the image source device and the reflector assembly independently, so that the image light emitted by the image source device can be better matched with the reflector assembly to adapt to more usage scenarios. Specifically, the first lifting mechanism 81 and the second lifting mechanism 82 can both be structures such as cylinders, hydraulic cylinders, and lead screw and nut assemblies, as long as they can realize the lifting and lowering of the image source device and the reflector assembly.
[0040] In some other embodiments, the second lifting mechanism 82 includes a first reflector element lifting mechanism and a second reflector element lifting mechanism. The first reflector element lifting mechanism drives the first reflector element to move up and down, and the second reflector element lifting mechanism drives the second reflector element to move up and down, thereby adjusting the height difference between the first and second reflector elements. This ensures that the image light emitted by the image source device passes through the path between the first and second reflector elements. The height difference between the first and second reflector elements can be adjusted as needed. Specifically, both the first and second reflector element lifting mechanisms can be structures such as cylinders, hydraulic cylinders, or lead screw and nut assemblies, as long as they can adjust the height of the first and second reflector elements independently.
[0041] In some embodiments, the second lifting mechanism 82 can be a specific structure capable of simultaneously lifting and lowering the first and second reflector elements in the reflector assembly. In other embodiments, the second lifting mechanism 82 may also include a first reflector element lifting mechanism and a second reflector element lifting mechanism for separately adjusting the lifting and lowering of the first and second reflector elements. There are no specific limitations on this, and different lifting mechanisms can be selected according to the actual scenario.
[0042] In this embodiment, an angle adjustment mechanism 9 is provided at the drive end of the lifting mechanism 8. The angle adjustment mechanism 9 includes a reflector angle adjustment mechanism 92 and an image source device angle adjustment mechanism 91. The reflector angle adjustment mechanism 92 is respectively located at the connection position between the first reflector element lifting mechanism and the first reflector element, and at the connection position between the second reflector element lifting mechanism and the second reflector element. The angle of the first reflector element and the second reflector element can be adjusted by the reflector angle adjustment mechanism 92 so that the image light emitted by the image source device 1 can reach the eye box position better through the first reflector element and the second reflector element, making it easier for the driver to view.
[0043] Furthermore, the reflector angle adjustment mechanism 92 can be a gear transmission mechanism. By installing the gear transmission mechanism between the first reflector element lifting mechanism and the first reflector element, and between the second reflector element lifting mechanism and the second reflector element, and then providing a motor for driving the gear transmission mechanism to rotate, the angle adjustment of the first and second reflector elements can be achieved. In other embodiments, the reflector angle adjustment mechanism 92 can also be a worm gear transmission rotation mechanism, an electrode drive rotation mechanism, etc., as long as it can achieve the adjustment of the rotation angle of the first and second reflector elements.
[0044] In this embodiment, the image source device angle adjustment mechanism 91 is located at the connection position between the first lifting mechanism 81 and the image source device. The angle of the image source device can be adjusted by the image source device angle adjustment mechanism 91 so that the image source device can better emit image light toward the reflector assembly and adapt to more viewing angles and scenes.
[0045] Furthermore, the image source device angle adjustment mechanism 91 can be a gear transmission mechanism, which is located at the connection position between the first lifting mechanism 81 and the image source device. By rotating the gear transmission mechanism, the angle of the image source device 1 can be adjusted. In other embodiments, the image source device angle adjustment mechanism 91 can also be a worm gear transmission rotation mechanism, an electrode drive rotation mechanism, etc., as long as it can achieve the adjustment of the rotation angle of the image source device.
[0046] In some other embodiments, the lifting mechanism can simultaneously move the image source device and the reflector assembly up and down. The lifting mechanism 8 includes a lifting cylinder and a bracket. The bracket is installed at the drive end of the lifting cylinder. The image source device and the reflector assembly are installed inside the bracket. When the lifting cylinder drives the bracket to move up and down, the image source device and the reflector assembly installed inside the bracket move up and down together, thereby adjusting the height of the instrument image through the lifting mechanism.
[0047] Meanwhile, the embedded real-image instrument panel of this application can replace the existing instrument panel in the vehicle, reducing the cost of the vehicle instrument panel, saving interior space, and providing diverse display effects that can be adjusted according to actual needs. Furthermore, since the instrument panel 6 only houses two key components—the image source device 1 and the reflector assembly—the overall structure is simple and clear, the number of parts is significantly reduced, and the size is effectively controlled. This compact design not only saves valuable interior space but also provides a buffer zone for the driver in the event of a potential accident, reducing the risk of secondary injury to the driver from the instrument panel.
[0048] In this embodiment, the field of view formed by the reflector assembly is 5°*3°. This field of view allows the driver to better view the instrument panel images, improving the driving experience. It ensures that the driver can easily capture vehicle instrument information displayed on the HUD system, such as speed, fuel level, and navigation instructions, while maintaining a normal driving posture, without frequently looking down at the instrument panel. This reduces the time the driver's eyes are off the road, improving driving safety. The 5°*3° field of view is designed to provide the driver with the optimal viewing experience. This angle is neither too narrow, resulting in incomplete information display, nor too wide, distracting the driver's attention. It ensures the clarity and readability of the information, allowing the driver to easily obtain the necessary information. Different driving scenarios and driving habits have different requirements for the field of view of the HUD system; the 5°*3° field of view serves as a balanced choice, satisfying the viewing needs of most drivers while maintaining good adaptability in different driving environments.
[0049] Setting the field of view to 5°*3° improves information acquisition efficiency. Within this field of view, the driver can quickly and accurately capture the vehicle instrument information displayed on the HUD system without excessive visual searching or adjusting their gaze, thus improving information acquisition efficiency. It also increases driving focus. Since the driver doesn't need to frequently look down at the instrument panel, they can focus more on the road and traffic conditions ahead, reducing potential safety hazards caused by shifting their gaze. This high level of driving focus contributes to improved overall driving safety and stability. Furthermore, it enhances driving comfort; an appropriate field of view design helps reduce driver visual fatigue. When viewing information within this angle range, the driver's eyes can maintain a comfortable viewing distance and angle, avoiding eye discomfort caused by prolonged focus on close-up objects.
[0050] In this embodiment, the first reflecting mirror 2 is a first curved mirror, and the second reflecting mirror 3 is a second curved mirror. In other embodiments, both the first reflecting mirror 2 and the second reflecting mirror 3 are concave mirrors. The radius of curvature of the concave mirror can be selected according to the actual imaging distance and imaging size, and is not specifically limited here. In this embodiment, the first and second curved mirrors are preferably freeform mirrors, that is, the curvature of each point on the mirror surface is different, which optimizes image quality and provides a better viewing experience for the driver.
[0051] Furthermore, the first curved mirror is smaller in width than the second curved mirror. In this embodiment, the first curved mirror is a small curved mirror, and the second curved mirror is a large curved mirror. The large curved mirror has the function of diverging the light beam. The light beam emitted by the image source device 1 is reflected by the small curved mirror to the large curved mirror, which increases the width of the light beam, allowing the image to be magnified and further making the image clearer. The smaller first curved mirror makes the entire optical path system more compact. In the case of limited space inside the vehicle, a compact design helps save space and avoids interference with the layout of other components in the cockpit. Although the size of the reflector directly affects its reflective area, a larger size does not necessarily mean better image quality. In the HUD system, the main function of the first curved mirror is to change the direction of the light beam so that it can smoothly enter the reflection area of the second curved mirror. Therefore, under the premise of ensuring unobstructed optical path, appropriately reducing the size of the first curved mirror can reduce unnecessary reflection and scattering, which helps to improve the clarity and contrast of the image. The manufacturing cost of optical components is usually proportional to their size and complexity. Therefore, while meeting imaging requirements, appropriately reducing the size of the first curved mirror can lower manufacturing costs and improve the product's cost-effectiveness. Curved mirrors may produce some distortion when reflecting light. For HUD systems, reducing the size of the first curved mirror may help reduce the degree of distortion, because a smaller reflective area means less bending of light on the mirror surface. A smaller first curved mirror may also have better adaptability, making it easier to integrate with other components and reducing installation difficulty and complexity.
[0052] In this embodiment, the dimensions of the first curved mirror are 200mm*100mm, and the dimensions of the second curved mirror are 160mm*120mm. The first curved mirror is narrow and long, while the second curved mirror is wide and short. The second curved mirror is wider, so that the width of the first curved mirror is smaller than that of the second curved mirror.
[0053] In this embodiment, the image source device 1 includes a backlight and an optical film. After the backlight emits a light beam, it passes through the optical film and transmits the vehicle instrument information carried on the screen to the position of the first curved mirror. The angle between the light beam emitted by the backlight and the screen is 82° with an error range of ±0.5′. The angle between the first curved mirror and the light beam emitted by the backlight is 70°±0.5′. The angle between the second curved mirror and the light beam reflected by the first curved mirror is 74°±0.5′. This ensures that the light beam carrying the vehicle instrument information emitted by the image source device 1 can be clearly reflected to the eye box 5.
[0054] In this embodiment, the distance between the imaging position and the eye box 5 is 550mm. This distance is crucial to ensuring that the driver can comfortably and clearly see the real image on the instrument panel. The 550mm setting is usually based on the eye distance and visual habits of most drivers, so that the real image can naturally fall within the driver's field of vision, reducing visual fatigue and discomfort. The distance between the imaging position and the large curved mirror is 450mm. This distance determines the path length of the light beam after reflection from the large curved mirror to the imaging position. The 450mm setting is precisely calculated to ensure that the light beam maintains sufficient brightness and clarity during transmission, while avoiding unnecessary aberrations or distortions. The distance between the large curved mirror and the small curved mirror is 250mm. This distance is one of the key aspects of optical path folding. By adjusting the distance between the large curved mirror and the small curved mirror, precise control of the beam propagation direction can be achieved, ensuring that the beam reaches the imaging position along a predetermined path. The setting of 250mm is based on the results of optical simulation and experimental verification to achieve optimal optical performance. The distance between the small curved mirror and the image source device 1 is 270mm. This distance determines the distance the beam emitted by the image source device 1 needs to travel before reaching the small curved mirror. The setting of 270mm takes into account the beam divergence angle, the small curved mirror's receiving angle, and the compactness requirements of the entire system. An appropriate distance ensures that the beam is fully reflected on the small curved mirror and continues to propagate along the predetermined optical path; where the distance is the optical path length of the beam emitted by the image source device 1.
[0055] In this embodiment, both the first and second curved mirrors are freeform mirrors. The extended polynomials of both mirrors have 20 terms, and each term in the extended polynomial has a different curvature. The extended polynomial is a mathematical model used to describe the surface shape of a curved mirror and is an important tool in freeform surface design. Setting different curvatures for each term in the extended polynomials of the first and second mirrors can create complex imaging effects. The curvature of the mirror determines its reflection and focusing characteristics. When the curvature changes complexly, i.e., the extended polynomial contains multiple different curvature terms, the mirror can produce more complex and refined imaging effects. This design can be used to manufacture optical elements with special imaging characteristics, reducing aberrations and improving image quality. Different curvature distributions can also achieve precise control over the beam shape. For example, by designing curved mirrors with specific curvature distributions, parallel beams can be converted into beams with specific shapes (such as ellipses, rectangles, etc.), or divergent beams can be focused into smaller spots, increasing the diversity of automotive virtual instruments. Complex curvature designs can also achieve some special optical functions, such as optical scanning, optical path folding, and optical filtering. Curved mirrors can be used for optical path folding to reduce the size and weight of optical systems. Traditional spherical mirrors produce aberrations such as spherical aberration during imaging, affecting image quality, while freeform mirrors, by precisely controlling the curvature distribution, can significantly reduce or eliminate these aberrations, thereby improving the clarity and resolution of the image.
[0056] In this embodiment, the radius of curvature of the first curved mirror is 556.6 mm, and the radius of curvature of the second curved mirror is 227 mm. The first curved mirror has a larger radius of curvature and a relatively flat surface. A larger radius of curvature helps to achieve a larger field of view because the light beam will not be overly focused during reflection, thus covering a wider range of viewing angles. The main function of the first curved mirror is to perform preliminary direction adjustment on the light beam emitted by the image source device 1, allowing it to smoothly enter the reflection area of the second curved mirror. The second curved mirror has a smaller radius of curvature and a more curved surface. A smaller radius of curvature helps to enhance the focusing effect of the light beam, allowing the light beam to be more concentratedly projected onto the imaging position after reflection, forming a clear and realistic instrument image.
[0057] In this embodiment, as Figure 1 As shown, after the image source device 1 emits a beam of light carrying vehicle instrument information, it is reflected by the first reflector 2 to the second reflector 3. The second reflector 3 reflects the beam of light to the dashboard 6. When the driver looks at the beam of light reflected by the second reflector 3 through the dashboard 6 from the position of the eye box 5, what he sees is actually the real image of the instrument on the back of the second reflector 3, thus forming a HUD imaging system so that the driver can see the real image of the instrument carrying vehicle instrument information emitted by the image source device 1.
