Detailed Implementation

[0020] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0021] like Figures 1-6 As shown, a waveguide display component for a marine HUD device mainly comprises a mounting component, a control module 400, an input module 500, an optomechanical system 600, and at least one waveguide display screen 100. The waveguide display screen 100, control module 400, and input module 500 are all mounted on the mounting component, while the optomechanical system 600 is housed within the mounting component. Both the input module 500 and the optomechanical system 600 are electrically connected to the control module 400.

[0022] The input module 500 receives information from the ship's display and control console and transmits the received information to the control module 400. The control module 400 processes the information received by the input module and, based on the number of waveguide displays, allocates display information to each waveguide display and transmits its content to the corresponding optomechanism. The optomechanism converts electrical signals into images on the waveguide displays, enabling the information to be displayed. The control module 400 uses a CPU with existing information receiving, transmitting, and processing functions, while the input module uses a CPU with existing information receiving, transmitting, and simple processing functions.

[0023] The number of optical waveguide displays can be set as needed. Preferably, the optical waveguide display 100 has three sides, and the left and right sides are at a certain angle to the front optical waveguide display. Each optical waveguide display 100 is fixed to the bottom shell 200 by a corresponding light shield 300, so that the operator can easily view different information.

[0024] Specifically, each optical waveguide display screen is configured as a rectangle composed of four small optical waveguide display screens spliced ​​together. Each small optical waveguide display screen is equipped with a corresponding optical engine, and the output light of the optical engine can illuminate the corresponding small optical waveguide display screen.

[0025] The optical waveguide display screen includes an optical waveguide sheet 110 and an organic glass layer 111 disposed on the front and rear sides of the optical waveguide sheet 110, which can effectively protect the surface of the optical waveguide sheet and prevent glass from breaking and injuring people in extreme cases. At the same time, the glass also has a light filtering effect, further ensuring the clarity of the display.

[0026] The mounting components include a base shell 200 and a light-shielding plate 300 arranged opposite each other. An input module 500 and a control module 400 are located on the upper and lower sides of the base shell 200, and an optical engine 600 is located inside the base shell 200. Preferably, both the base shell and the light-shielding plate are made of aluminum alloy.

[0027] The base shell 200 includes two bottom beams 210 arranged vertically opposite each other. Mounting boxes 220 for mounting the optical engine 600 are provided on the bottom beams 210 on both the left and right sides of each optical waveguide display screen 100. The front of the mounting box 220 is open, and a light-shielding plate can cover the mounting box. The upper and lower ends of the mounting box 220 are mounted to the corresponding bottom beams 210. At least two mounting blocks 230 are provided inside the mounting box 220 for mounting the light-shielding plate 300. A through hole is provided on the mounting block corresponding to the optical engine to allow the output light from the optical engine to illuminate the optical waveguide display screen. The overall structure is simple and lightweight, and the mounting boxes can effectively block the gap between the rear sides of adjacent optical waveguide display screens.

[0028] When an optical waveguide display screen 100 is provided, the mounting box 220 includes a main box body 221 and a cover plate 222 disposed on the side of the main box body 221, and the cover plates 222 of the two mounting boxes 220 are located on the inner side. Correspondingly, the optical engine 600 and the mounting block 230 are both mounted on the cover plate 222.

[0029] When two or more optical waveguide displays 100 are installed, the structure of the mounting boxes 220 located on both sides is the same as the structure of the mounting box 220 when one optical waveguide display 100 is installed. The mounting box 220 located in the middle includes a back plate 223 arranged in a U-shape and side cover plates 224 arranged on the left and right sides of the back plate. Correspondingly, the optical engine 600 and the mounting block 230 are both installed on the side cover plates 224.

[0030] Each bottom beam 210 has a right-angle bend 211 at its front end to limit the optical waveguide display screen from the rear, and a receiving groove for accommodating the optical waveguide display screen is provided at the rear end of the light shield.

[0031] To enable interaction between the operator and the optical waveguide display screen, a visual recognition module 700 is installed on the base shell 200. Simultaneously, an interactive information processing module 800, electrically connected to the visual recognition module, is installed inside the base shell 200 and is also electrically connected to the control module. The visual recognition module uses cameras, preferably two cameras, to reduce blind spots. The interactive information processing module processes the motion information captured by the visual recognition module, combines it with signals provided by the input module to form a new input image generation unit, and then transmits it to the control module for processing. The interactive information processing module employs existing technologies with information processing, information receiving, and information transmission functions.

[0032] To facilitate the installation of the entire equipment within the ship's bridge, a mounting bracket 900 is also provided, such as... Figure 6 As shown. Specifically, the mounting bracket includes a vertical frame 910 connected to the bottom shell and a horizontal frame 920 connected to the top or ground of the bridge. A reinforcing rib 930 is provided between the vertical and horizontal frames. To facilitate adjustment of the HUD device's installation height, multiple mounting holes 901 are spaced vertically on the horizontal frame. To ensure support strength, both the horizontal and vertical frames have two vertical frames spaced apart on the left and right sides, with a connecting frame located at the rear of the bottom shell between the two vertical frames. Additionally, a mounting block can be provided at the rear of the bottom shell to facilitate connection between the vertical frames and the bottom shell. The mounting bracket can also employ other structures to integrate it into the display console or operating panel of the ship's bridge.
