[0023] The present invention will be further described in detail below through specific embodiments. The following embodiments are merely descriptive and not restrictive, and the protection scope of the present invention cannot be limited by them.

[0024] A guide display device for large vehicles, the innovation of which is: comprising a mounting frame, the mounting frame comprising a back plate, a top plate 4, a bottom plate 8, and side plates 5, the top plate and the bottom plate are arranged parallel to each other in an upper and lower direction, a back plate is arranged between the rear parts of the top plate and the bottom plate, and side plates are arranged on the left and right sides of the back plate;

[0025] A main grating display screen 6 is arranged on the upper half of the back plate, and a main grating 10 with a straight structure with uniform vertical spacing is displayed on the main grating display screen. A folded line indicator grating 9 with uniform spacing is buckled at the front end of the main grating display screen, and the obtuse angle of the indicator grating is arranged opposite to the main grating display screen, and each of the indicator gratings and the main grating is arranged staggered. Figure 2 As shown, the indicator grating is a broken line structure, that is, a flat vertical line grating plate is bent along the middle of the horizontal direction to form a buckle plate structure.

[0026] The side plate is a right-angled trapezoidal structure with a wide top and a narrow bottom. The wider top part is used to block the light transmission from the sides of the indicator grating and the main grating to ensure that the device effectively guides the driver. At the same time, the structure of wide top and narrow bottom makes the device look more light and beautiful as a whole.

[0027] The guiding display principle of the utility model is realized based on moiré fringes, that is, after the main grating of the vertical straight line structure is superimposed with the broken line indicator grating, under the influence of the deviation angle, the front and rear gratings undergo optical interference to form an indicator arrow for the vehicle. The driver can adjust the vehicle according to the indicator arrow he sees, which is simple and convenient.

[0028] In order to meet the diversified usage needs of the airport, the utility model also designs a real-time information display mechanism, which includes a real-time information display screen 7 and a camera 1. In the attached figure, the real-time information display screen displays a "STOP" sign. A mounting block 3 is provided at the lower part of the top plate of the mounting frame, and mounting grooves 2 are symmetrically provided at both ends of the mounting block. Cameras are respectively installed in the mounting grooves. A real-time information display screen is provided at the lower part of the main grating display screen on the lower half of the back plate of the mounting frame. The camera is electrically connected to the real-time information display screen, and the camera displays the real-time captured picture on the real-time information display screen. The display screen can also display information such as flights and expected landing time of the airport as needed, so as to facilitate information acquisition.

[0029] A wireless receiver is provided on the real-time information display screen for receiving information from related systems as required.

[0030] The guiding principle of the utility model is:

[0031] like Figure 3As shown, when the vehicle driver observes the guidance display device, if the moiré fringes show rightward indicating fringes, it means that the vehicle is deviating to the left relative to the device, and the vehicle needs to be adjusted to the right until the moiré fringes seen by the driver are vertical fringes; Figure 4 As shown, if the moiré fringes show leftward indicating fringes, it means that the vehicle is deviating to the right relative to the device, and the vehicle needs to be adjusted to the left until the moiré fringes seen by the driver are vertical fringes;

[0032] like Figure 1 As shown, when the moiré fringes seen by the driver are vertical fringes, it means that the vehicle is facing the device and the vehicle has been adjusted to the correct position.

[0033] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will appreciate that various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
