Detailed Description
In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
It will be understood that when an element is referred to as being "mounted" or "disposed" on another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
It should be noted that terms of left, right, up, down, etc. in the following embodiments are merely relative concepts or references to normal use states of the product, and should not be construed as limiting.
As shown in fig. 1 to 4, the head-up display device 100 provided in the embodiment of the invention is used with an image display unit, and includes an image generating unit 200 and an image projection unit disposed between the image generating unit 200 and the image display unit, wherein the image generating unit 200 can generate at least a first light beam 211 representing a first image and a second light beam 221 representing a second image; the image projection unit at least comprises a first optical module and a second optical module, the first optical module reflects and expands the first light beam 211 to form a first emergent light beam 213, the second optical module reflects and expands the second light beam 221 to form a second emergent light beam 223, and the first optical module and the second optical module are configured to enable the first emergent light beam 213 and the second emergent light beam 223 to deviate from each other at an included angle, so that the corresponding first virtual image frame 510 and the second virtual image frame 520 which are distributed in a non-overlapping mode on the image display unit can be imaged and projected to a visual field of a user.
According to the head-up display device 100 of the embodiment of the invention, the first optical module and the second optical module are adopted to reflect and expand the first light beam 211 of the first image and the second light beam 221 of the second image respectively, so that the size of an optical element is reduced, the installation is more flexible and convenient, the head-up display device can better adapt to a narrow installation space, compared with a light splitting unit, in actual use, the relative positions between the first optical module and the second optical module are only required to be correspondingly adjusted, the first light beam 211 and the second light beam 221 can be conveniently made to form a first emergent light beam 213 and a second emergent light beam 223 which deviate from each other and form a proper included angle according to the light path indicated by a solid arrow, the first emergent light beam 211 and the second emergent light beam 223 are simultaneously displayed and imaged respectively in different areas of an image display unit, the first virtual image picture 510 and the second virtual image picture 520 which are not overlapped and distributed can be greatly increased, the interaction effect is better, the head-up display device is more convenient to install and use, and the head-up display device is more practical.
The image display unit is a conventional structure or component, for example, when the head-up display device 100 is applied in a vehicle, the image display unit may be a transparent plate disposed behind the windshield 400 and having a relevant functional film layer; in order to further simplify the structure and enhance the driving feeling of the driver, it is more preferable to directly use the windshield 400 of the vehicle as the image display unit.
Further, in an embodiment of the present invention, the first optical module and the second optical module each include a sub-reflection part and a main reflection part to reflect and expand the respective first light beam 211 and second light beam 221 twice. The structure can enable the first light beam 211 and the second light beam 221 to be reflected and expanded to be displayed in a larger area in the image display unit, and can obtain a larger virtual image picture under the condition of adopting the smaller image generation unit 200, thereby being beneficial to achieving better augmented reality effect, not needing to increase the volume of the whole head-up display device 100, being more suitable for being used in a narrow installation space, and further solving the problem that the volume is small and the imaging is difficult to be compatible.
Further, in the embodiment of the present invention, the sub-reflecting portion of the first optical module is provided by the first sub-mirror 311, the sub-reflecting portion of the second optical module is provided by the second sub-mirror 321, and the main reflecting portion of the first optical module and the main reflecting portion of the second optical module are provided by the same main mirror 330.
The first light beam 211 is reflected by the first sub-mirror 311 to generate a first incident light beam 212 projected towards the main mirror 330, and then reflected by the main mirror 330 and expanded to be projected to the windshield 400 as a first emergent light beam 213; the second light beam 221 is reflected by the second secondary mirror 321 to generate a second incident light beam 222 projected towards the main mirror 330, and then reflected by the main mirror 330 and expanded to be projected to the windshield 400 as a second emergent light beam 223; finally, the first outgoing beam 213 and the second outgoing beam 223 are reflected by the windshield 400 to the eyes of the user, and the user can perceive a first virtual image 510 conjugated with the first image and a second virtual image 520 conjugated with the second image in front of the windshield 400 according to the optical principle. The first sub-mirror 311 and the second sub-mirror 321 disposed respectively are more beneficial to keeping and adjusting the first incident light beam 212 and the second incident light beam 222 and the first emergent light beam 213 and the second emergent light beam 223 to project according to different light paths, thereby being more convenient to realize a first virtual image picture 510 and a second virtual image picture 520 which are not overlapped. The head-up display device 100 shares the same main mirror 330 for reflection and beam expansion, can greatly reduce the width of the lens of the main mirror 330, and is beneficial to miniaturizing the whole structure of the head-up display device 100 while realizing double-picture display with a large viewing angle so as to be more convenient for installation and arrangement in a limited space.
In particular, in practical applications, since the smaller image generating unit 200 is preferably adopted, the first sub-mirror 311 and the second sub-mirror 321 corresponding to the image generating unit 200 are relatively smaller in size, and the main mirror 330 has a larger size than the first sub-mirror 311 and the second sub-mirror 321, so as to facilitate improving the overall compactness and reducing the volume. Of course, the main mirror 330 may be reduced in size as much as possible on the premise that the first virtual image screen 510 and the second virtual image screen 520, which do not overlap, are obtained by adjusting the relative positions of the first sub mirror 311, the second sub mirror 321, and the main mirror 330.
Further, in the embodiment of the present invention, the first sub-mirror 311 and the second sub-mirror 321 are spatially distributed from top to bottom with respect to the main mirror 330, and the exit angle of the second exit beam 223 formed by sequentially reflecting and expanding the beam by the second sub-mirror 321 and the main mirror 330 is larger than the exit angle of the first exit beam 213 formed by sequentially reflecting and expanding the beam by the first sub-mirror 311 and the main mirror 330. As shown in fig. 1 and fig. 2, the first virtual image 510 is located in an upper region of the image display unit, and the second virtual image 520 is located in a lower region of the image display unit, so that the first virtual image 510 and the second virtual image 520 that are vertically distributed are better prevented from overlapping. The virtual images distributed up and down provide a larger angle of view for the user, and are more convenient for the user to watch.
Taking an application in a vehicle as an example, the image generated by the image generating unit 200 includes any two or three of a running information image, an instrument display image, and a navigation information image. Since the first virtual image 510 corresponding to the driving information image and the navigation information image generally requires a large area and a large viewing angle for display, and the display area of the meter display image is relatively small, the first image represented by the first light beam 211 reflected by the first sub-mirror 311 can be used to present the augmented reality information of road conditions, such as lane departure, pedestrian identification, road barrier identification, etc., i.e., the first image corresponds to the driving information image and the navigation information image, and the second image represented by the second light beam 221 reflected by the second sub-mirror 321 is used to present the relevant parameter information of the vehicle, such as vehicle speed, fuel consumption, temperature, warning, etc., i.e., the second image corresponds to the meter display image, thereby providing better driving experience for the driver. On this basis, the size of the first auxiliary mirror 311 is preferably larger than that of the second auxiliary mirror 321, so that the first virtual image 510 can be displayed in a large area and a large viewing angle, and other complex optical components such as lenses for amplifying images are not required to be additionally arranged, thereby achieving the purpose of further simplifying the overall structure.
By further simply adjusting the corresponding angles of the first sub-mirror 311, the second sub-mirror 321 and the main mirror 330, the first light beam 211 and the second light beam 221 can be reflected twice and expanded to form a first virtual image 510 and a second virtual image 520 which are spliced up and down on the windshield 400 as shown in fig. 2, so that the overall display field angle can be further enlarged, and a better visual effect can be achieved.
Further, in the embodiment of the present invention, in order to reduce the display size of the overall head-up display device 100, the two areas of the image generating unit 200 where the first image and the second image are generated are usually close to each other or spliced, so that in order to ensure that the first sub-mirror 311 and the second sub-mirror 321 can simultaneously and better correspondingly receive the first light beam 211 representing the first image and the second light beam 221 representing the second image, and the structure is more compact, the first sub-mirror 311 and the second sub-mirror 321 are preferably disposed adjacent to each other. Since the image display unit (the windshield 400 in the present embodiment) is generally irregularly inclined, in a vehicle driving right, the right portion of the windshield 400 is relatively forward and the left portion is relatively backward, i.e. the left portion is inclined to the left, in view of the driver, so that the first virtual image 510 and the second virtual image 520 are imaged in front of the driver, and according to the related optical principle and multiple installation tests, the first sub-mirror 311 and the second sub-mirror 321 are asymmetrically distributed with respect to the main mirror 330 in practical application.
Specifically, as shown in fig. 5, in the side view direction with reference to the user, the main mirror 330 is substantially vertically arranged with respect to the windshield 400 in the side view direction of the windshield 400, the first sub mirror 311 and the second sub mirror 321 are corresponding to the main mirror 330 with a certain distance, the first sub mirror 311 and the second sub mirror 321 are disposed at a substantially constant obtuse angle therebetween, the image generating unit 200 is disposed below the first sub mirror 311 and the second sub mirror 321, and the image generating unit 200 is disposed at a substantially constant acute angle with respect to the first sub mirror 311 and the second sub mirror 321. In the front view direction based on the user, as shown in fig. 6, the first sub-mirror 311 and the second sub-mirror 321 are located in the right direction of the main mirror 330, the first sub-mirror 311 and the second sub-mirror 321 are asymmetrically distributed in the left-right direction and the up-down direction with respect to the main mirror 330, and the first sub-mirror 311 and the second sub-mirror 321 are staggered at an acute angle.
Further, when the second virtual image frame 520 is used for presenting the instrument display information as described above, the image area is relatively small, so that in order to enable the human eye to correctly or completely see the second virtual image frame 520 and have a good visual effect, that is, have sufficient upper and lower eye-box sizes, in the embodiment of the present invention, the central ray of the second incident light beam 222 reflected by the second sub-mirror 321 corresponds to the central position of the main mirror 330 or corresponds to the position adjacent to the center of the main mirror 330. Of course, the central light of the first incident beam 212 reflected by the first sub-mirror 311 also preferably corresponds to the central position of the main mirror 330 or corresponds to the position adjacent to the center of the main mirror 330, so that the driver can obtain a better view. In addition, such a structure is also advantageous in further reducing the size of the main mirror 330.
Further, in the embodiment of the present invention, the main mirror 330 is a concave mirror, and the first sub-mirror 311 and the second sub-mirror 321 are any one of a planar mirror, a concave mirror and a convex mirror, respectively. The first secondary mirror 311 and the second secondary mirror 321 may be selected according to the actual optimization design requirement, and in conjunction with fig. 1 to fig. 4, in this embodiment, the first secondary mirror 311 and the second secondary mirror 321 are convex mirrors.
In the embodiment of the invention, the main mirror 330, the first auxiliary mirror 311 and the second auxiliary mirror 321 all use the optical principle of amplifying the virtual image vertically to generate the virtual image, and image the virtual image in a large area manner in front of the windshield 400, so that a larger field angle is provided, which is beneficial to achieving a better augmented reality effect.
In particular, in this embodiment, the primary mirror 330 is preferably an off-axis concave aspherical mirror of the prior art. Therefore, the distortion of the windshield 400 caused by imaging can be corrected by utilizing the structure of the main mirror 330 without additionally arranging an optical film layer on the windshield 400 or specially designing the windshield 400, which is beneficial to further simplifying the whole structure and improving the compactness of the structure.
In particular, since the surface of the windshield 400 is generally aspherical and curvatures in different regions are different, the surface patterns of the first sub-mirror 311 and the second sub-mirror 321 are also preferably aspherical, and the first sub-mirror 311 and the second sub-mirror 321 further preferably have different surface patterns, that is, both have different curvatures. This allows for better correction of image distortion problems when imaging on the windshield 400 by optimizing the surface reflection profile of the mirror, thereby providing the user with two high quality low distortion images.
Further, as shown in fig. 5 and fig. 6, in the embodiment of the present invention, the effective reflection surface areas of the first auxiliary mirror 311, the second auxiliary mirror 321 and the main mirror 330 are all irregular quadrilaterals, and multiple experiments show that such a structure can better correct the distortion of the image on the windshield glass, and ensure the imaging definition.
Further, in the embodiment of the present invention, the image generating unit 200 includes two imaging sources, and the first image and the second image are respectively generated by the two imaging sources (the first imaging source 210 and the second imaging source 220) in a one-to-one correspondence. The arrangement of the first imaging source 210 and the second imaging source 220 and the first sub-mirror 311 and the second sub-mirror 321 can be more flexible, for example, in practical application, the first imaging source 210 and the second imaging source 220 and the first sub-mirror 311 and the second sub-mirror 321 may be distributed in a staggered manner as shown in fig. 1 and 2, or may be distributed in a parallel manner as shown in fig. 3.
In connection with fig. 4, it is more preferable that the image generating unit 200 includes an imaging source, and the first image and the second image are generated by different regions of the same imaging source, so as to further simplify the complexity of the image generating unit 200 and reduce the related production cost.
In addition, if the purpose of multi-area display is required, an imaging source or an imaging area of the imaging source and a secondary mirror can be correspondingly additionally arranged.
In embodiments of the invention, the imaging source is an existing liquid crystal display, paper display, or an image projected onto the imaging film by a digital projector or Lcos micro projector.
As shown in fig. 7, the embodiment of the invention further provides a vehicle, which includes a vehicle body 600, a console 700 and a windshield 400 disposed in the vehicle body 600, and the head-up display device 100, wherein the head-up display device 100 is disposed below the console 700, and the windshield 400 is used as an image display unit that is used in cooperation with the head-up display device 100.
According to the vehicle provided by the embodiment of the invention, by arranging the head-up display device 100, a larger visual angle can be provided for a driver, the comfort and safety of the driver for checking related information in the driving process are improved, a better actual interaction effect can be achieved between the driver and the information displayed by the head-up display device 100, and driving safety accidents can be better avoided.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
