[0022] In order to facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0023] See also Figure 1 and Figure 2As shown, a vehicle-mounted display screen structure 10 includes: a housing 100 and an optical display module 200. The housing 100 is provided with a mounting cavity. The optical display module 200 is disposed within the mounting cavity and includes a display screen 210, a plane mirror 220, a secondary reflector 230, and a tertiary reflector 240. The plane mirror 220 and the secondary reflector 230 are disposed opposite each other, and the tertiary reflector 240 is located above the plane mirror 220. The plane mirror 220 and the secondary reflector 230 adjust the optical path of the display screen 210 so that the light of the display screen 210 is reflected to the tertiary reflector 240. The tertiary reflector 240 is configured to reflect the light of the display screen 210 toward the eye position and form a virtual image. Specifically, the vehicle-mounted display screen structure can be installed in the passenger seat of a vehicle or behind the front seats for viewing by the passenger or rear passengers. By using the plane mirror 220, the secondary reflector 230 and the tertiary reflector 240 in the optical display module 200 of the present invention, a virtual large screen and long-distance imaging effect can be achieved, thereby improving the visual experience of passengers.

[0024] It should be noted that, specifically, please participate Figure 1 and Figure 2As shown, the display screen 210 and the secondary reflector 230 are respectively located at opposite ends of the plane mirror 220, and the tertiary reflector 240 is located between the display screen 210 and the secondary reflector 230. Furthermore, the display screen 210 and the plane mirror 220 are tilted relative to each other to form a first predetermined angle, and the secondary reflector 230 and the plane mirror 220 are tilted relative to each other to form a second predetermined angle. In this embodiment, the plane mirror 220 and the tertiary reflector 240 are all tilted. That is, the display screen 210, the plane mirror 220, the secondary reflector 230, and the tertiary reflector 240 are positioned such that light from the display screen 210 ultimately passes through the viewing window of the housing 100 and is ultimately reflected toward the eye, allowing the passenger to see a virtual magnified image. Specifically, the plane mirror 220 is tilted, and the display screen 210 located at one end of the plane mirror 220 is tilted relative to the plane mirror 220 to form a first preset angle. The secondary reflector 230 located at the other end of the plane mirror 220 is tilted relative to the plane mirror 220 to form a second preset angle. The tertiary reflector 240 located above the plane mirror 220 is also tilted. At the same time, in this embodiment, the tertiary reflector 240 is positioned near the viewing window. Furthermore, light emitted by the display screen 210 to display the image is first projected onto the plane mirror 220, reflected by the plane mirror 220 to the secondary reflector 230, and simultaneously the secondary reflector 230 performs secondary reflection on the light to the plane mirror 220, thereby changing the emission path of the light through the plane mirror 220 and the secondary reflector 230, so that the light is reflected again by the plane mirror 220 to the tertiary reflector 240, and then reflected by the tertiary reflector 240 to the eye position to form a virtual image. For example, the secondary reflector 230 is a free-form surface mirror. For example, the plane mirror 220 is tilted at an angle of 39° relative to the horizontal plane, the display screen 210 is at a first preset angle of 64° relative to the plane mirror 220, the secondary reflector 230 is at a second preset angle of 45° relative to the plane mirror 220, and the tertiary reflector 240 is tilted at an angle of 39° relative to the horizontal plane. This allows light to pass through the viewing window of the housing 100 and be reflected to the eye position. Furthermore, the structure of the present invention can make the overall structure of the vehicle-mounted display screen structure more compact. In the present invention, the overall volume of the vehicle-mounted display screen 210 structure is between 10L and 20L. Through the present invention, a long-distance large-screen image with an image distance of 3m and a virtual image magnification of 6 times can be achieved.

[0025] Preferably, the housing 100 is a black housing 100 to prevent light from passing through the housing 100 .

[0026] Preferably, the display screen 210 is a TFT (Thin Film Transistor) display screen 210 .

[0027] Preferably, a viewing window is provided on one side of the housing 100 , and a glass lens is installed on the viewing window.

[0028] In one embodiment, AR (Anti-Reflection Glass) layers are provided on both sides of the glass lens. The AR layer reduces light reflection and enhances light transmittance, thereby ensuring the display effect and improving the viewing experience. For example, the AR layer can be an AR coating layer, that is, the AR coating material is directly deposited on the glass lens using vapor deposition technology, so that the glass lens has an anti-reflection effect; preferably, the thickness of the AR coating layer is 100nm-200nm, for example. The thickness of the AR coating layer is 120nm. In another embodiment, the AR layer can also be an AR plastic film layer, that is, a plastic film is used as a substrate, and an anti-reflection material is provided on the plastic film so that the plastic film has an anti-reflection effect, and then the plastic film is adhered to the glass lens through an adhesive. In this way, when the AR layer is worn, the AR plastic film layer can be directly replaced without replacing the glass lens.

[0029] In one embodiment, an anti-fouling and anti-fingerprint layer is provided on the side of the glass lens away from the optical display module 200. The anti-fouling and anti-fingerprint layer is an anti-fouling and anti-fingerprint coating layer, which makes the glass lens anti-fouling and anti-fingerprint, and prevents dirt on the glass lens from affecting the display effect.

[0030] See also Figure 3 As shown, in one embodiment, a mounting bracket 300 is provided at the bottom of the housing 100. The mounting bracket 300 includes a first mounting portion, a connecting portion, and a second mounting portion. The first mounting portion is connected to the bottom of the housing 100. For example, the first mounting portion can be fixed to the housing 100 using screws or other threaded fasteners. The ends of the connecting portion are respectively connected to the first mounting portion and the second mounting portion, so that the second mounting portion is suspended relative to the first mounting portion, facilitating the installation and fixing of the second mounting portion to the vehicle interior. For example, the second mounting portion can be installed and fixed to the vehicle interior using screws or other threaded fasteners. In this embodiment, the mounting bracket 300 is an integrally formed structure, for example, processed using a bending process, thereby ensuring the strength of the mounting bracket 300.

[0031] In one embodiment, a heat dissipation hole 110 is opened on the side wall of the housing 100 , and the heat dissipation effect of the vehicle-mounted display screen structure is improved through the heat dissipation hole 110 .
