A large viewing angle automobile instrument panel floating display device

Abstract

This invention discloses a wide-viewing-angle floating display device for automotive dashboards, comprising: an image source, a first reflector, and a second reflector. The first reflector is positioned on the side from which the light from the image source is emitted, and the second reflector is positioned on the side from which the light from the first reflector is emitted. A raw light beam emitted from the image source travels forward to the first reflector, where it is reflected again. The reflected beam then travels forward to the second reflector, where it is reflected once more, ultimately forming a real image visible to the human eye in the air. This invention utilizes a non-coaxial optical path design with dual reflectors and a freeform surface compensation technique. While maintaining system compactness, it overcomes the inherent contradiction between field of view and image quality in traditional reflective optical systems, enabling both the driver and passenger to see the same real image simultaneously, significantly expanding the field of view and enhancing the user experience.

Description

Technical Field

[0001] This utility model relates to the technical field of vehicle-mounted floating display devices, and in particular to a large-view floating display device for automotive dashboards. Background Technology

[0002] In recent years, private cars have gradually become an essential asset for every family, resulting in a huge market. To enhance their competitiveness and gain more market share, automakers are focusing on intelligent driving, using technology to simplify user operations and improve the user experience.

[0003] In automotive intelligent driving systems, incorporating VPA can greatly enhance the sense of technology and improve the user experience.

[0004] Compared to conventional VPA, the floating display device on the car dashboard uses negative refraction glass for a simple refraction light path. The wide-view car dashboard floating display device uses a non-coaxial light path design with dual reflectors and freeform surface compensation technology to make the real image float clearly in the air. This allows both the driver and passenger to see the same image at the same time, greatly improving the human-computer interaction and user experience.

[0005] However, current VPA systems generally use negative refractive glass for imaging, which has a simple optical path design but is costly and has a small field of view. Utility Model Content

[0006] The main purpose of this invention is to propose a floating display device for automotive dashboards with a specific viewing angle, aiming to enable the driver and passenger to view the same image simultaneously while ensuring image quality, thereby improving the user experience.

[0007] To achieve the above objectives, this utility model proposes a wide-view floating display device for automotive dashboards, comprising: an image source, a first reflector, and a second reflector.

[0008] The first reflector is positioned on the side from which the light from the image source is emitted, and the second reflector is positioned on the side from which the light from the first reflector is emitted. The original light beam emitted from the image source is transmitted forward to the first reflector, and after reaching the first reflection, it is reflected at the first reflector. The reflected light beam is then transmitted forward to the second reflector. After reaching the second reflector, the light beam is reflected again at the second reflector, and finally, a real image that can be observed by the human eye is formed in the air.

[0009] A further technical solution of this utility model is that the image source system is any one of a TFT system, a DLP system, or an LCOS system.

[0010] A further technical solution of this utility model is that the first reflector and the second reflector are one of a spherical reflector, an aspherical reflector, or a freeform surface reflector.

[0011] A further technical solution of this utility model is that the original light beam emitted from the image source, the light beam reflected from the first reflector, and the light beam reflected from the second reflector form a Z-shape.

[0012] The beneficial effects of this large-viewpoint floating display device for automotive dashboards are:

[0013] Through the above-mentioned technical solution, this utility model adopts the synergistic effect of the non-coaxial optical path design of dual reflectors and freeform surface compensation technology. While maintaining the system's compactness, it breaks through the inherent contradiction between field of view and image quality in traditional reflective optical systems, enabling the driver and passenger to see the same real image simultaneously, greatly expanding the field of view and improving the user experience.

[0023] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Considering that current VPA systems generally use negative refractive glass for imaging, the optical path design is simple, but the cost is high and the field of view is small, this utility model proposes a solution.

[0026] Specifically, this invention proposes a large-view floating display device for automotive dashboards. Compared to the small field of view of traditional VPAs, which can only guarantee viewing from a single position, this device can be placed in the center of the 1P dashboard, so that the image is projected above the center of the 1P dashboard. Through the synergistic effect of the non-coaxial optical path design of the dual reflective mirrors and the freeform surface compensation technology, while maintaining the compactness of the large-view floating display device for automotive dashboards, it overcomes the inherent contradiction between the field of view and image quality in traditional reflective optical systems. This allows the driver and passenger to see the same real image simultaneously, greatly expanding the field of view and significantly improving the customer experience.

[0027] like Figure 1 and Figure 2 As shown, a preferred embodiment of the large-view automotive dashboard floating display device of this utility model includes an image source 1, a first reflector 2, and a second reflector 3.

[0028] The first reflector 2 is disposed on the side from which the light source 1 is emitted, and the second reflector 3 is disposed on the side from which the light source 2 is emitted.

[0029] The original light beam emitted from the image source 1 is transmitted forward to the first reflector 2. After reaching the first reflector, it is reflected at the first reflector 2. The reflected light beam is transmitted forward to the second reflector 3. After reaching the second reflector 3, it is reflected again at the second reflector 3. Finally, a real image 4 that can be observed by the human eye 5 is formed in the air.

[0030] It should be noted that in this embodiment, the terms "first reflector 2" and "second reflector 3" are used for ease of description only and do not mean that only two mirrors and their corresponding order are used. More mirrors can be added as needed, and the reflected light path will still be valid.

[0031] Furthermore, in this embodiment, the image source 1 system is any one of a TFT system, a DLP system, or an LCOS system.

[0032] In this embodiment, the first reflector 2 and the second reflector 3 can be selected from one of a spherical reflector, an aspherical reflector, or a freeform surface reflector.

[0033] In this embodiment, the original light beam emitted from the image source 1, the light beam reflected from the first reflector 2, and the light beam reflected from the second reflector 3 form a Z-shape.

[0034] The beneficial effects of this large-viewpoint floating display device for automotive dashboards are:

[0035] Through the above-mentioned technical solution, this utility model adopts the synergistic effect of the non-coaxial optical path design of dual reflectors and freeform surface compensation technology. While maintaining the system's compactness, it breaks through the inherent contradiction between field of view and image quality in traditional reflective optical systems, enabling the driver and passenger to see the same real image simultaneously, greatly expanding the field of view and improving the user experience.

[0036] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
