DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0027] Reference Figure 1-Figure 4 A head-up display for a truck with an anti-blocking function includes a head-up display body 1, a free-form surface mirror 2 is provided on one side of the head-up display body 1, the head-up display body 1 and the free-form surface mirror 2 are packaged under the IP platform of the truck, a plane mirror 3 is provided obliquely above the free-form surface mirror 2, a windshield 4 is provided on one side of the plane mirror 3, and an observation point 5 is provided on one end of the windshield 4 close to the plane mirror 3.

[0028] Reference Figure 1-Figure 2 A virtual image surface 6 is provided on the front side of the windshield 4 , and an observation point 5 is located on one side of the virtual image surface 6 . The observation point 5 is used to observe and feel the virtual image surface 6 located in front of the windshield 4 .

[0029] First, the head-up display body 1 and the free-form mirror 2 are installed under the IP platform of the truck. Then, when in use, the light emitted by the head-up display body 1 is reflected for the first time by the free-form mirror 2. The light reflected by the free-form mirror 2 installed under the IP platform of the truck reaches the plane mirror 3, and the plane mirror 3 reflects the light for the second time; the light reflected by the plane mirror 3 reaches the windshield 4, and the windshield 4 reflects the light for the third time; the light after three reflections enters the observation point 5 (human eye), and the human eye perceives the virtual image located on the virtual image surface 6 in front of the windshield 4.

[0030] The plane mirror 3 is only used to fold the optical path and adjust the direction of the light after being reflected by the windshield 4. The light after being reflected by the plane mirror 3 reaches the free-form surface mirror 2. The free-form surface mirror 2 is used to balance the aberration of the windshield 4 to achieve better imaging quality.

[0031] The head-up display body 1 and the free-form mirror 2 can be packaged and sunk under the IP platform, while the plane mirror 3 can be located on the IP platform and not participate in the integration, which effectively reduces the problem of excessive volume, does not block the driver's field of vision, and maintains a good driving experience and safety.

[0032] Reference Figure 3 Figure 4 A connecting block 15 is fixedly connected to the bottom of the head-up display body 1, and a rotating rod 10 is fixedly connected inside the connecting block 15. Both ends of the rotating rod 10 are provided with fixing plates 9, and the two fixing plates 9 are rotatably connected to the two ends of the rotating rod 10 respectively. The bottoms of the two fixing plates 9 are fixedly connected to mounting plates 7, and mounting holes 8 are opened inside the two mounting plates 7.

[0033] The mounting plate 7 and the mounting hole 8 are used to mount the head-up display body 1 to prevent the head-up display body 1 from shaking or loosening when the vehicle is driving.

[0034] Reference Figure 3 Figure 4 One end of a fixed plate 9 is fixedly connected to a placement box 11, a motor 12 is arranged inside the placement box 11, a rod body is rotatably connected inside the placement box 11, the rod body is fixedly connected to the output end of the motor 12, a small gear 13 is fixedly connected to the outer wall of the rod body, one end of the rotating rod 10 extends through the interior of the placement box 11 and is fixedly connected to a large gear 14, and the small gear 13 is meshed with the large gear 14.

[0035] Drivers of different heights will have different sight heights, so when the position of the virtual image plane 6 on the windshield 4 needs to be changed, the motor 12 drives the small gear 13 to rotate, and the rotation of the small gear 13 drives the rotating rod 10 inside the large gear 14 to rotate. The rotation of the rotating rod 10 will drive the head-up display body 1 to rotate, so that the position of the virtual image plane 6 can be adapted to the sight range of different drivers to meet the needs of different drivers.

[0036] Reference Figure 1-Figure 4 The surfaces of the free-form mirror 2 and the plane mirror 3 are coated with a reflective coating and a protective coating.

[0037] Both the free-form mirror 2 and the plane mirror 3 need to reflect the display content, so a material with high reflectivity needs to be coated on their surfaces. Silver or aluminum is a commonly used high reflectivity material, which can effectively reflect light and produce a clear and bright projection image.

[0038] The protective coating can protect the reflective coating from scratches, contamination or oxidation.

[0039] Working principle: When in use, the light emitted by the head-up display body 1 is reflected for the first time by the free-form mirror 2, and the light reflected by the free-form mirror 2 installed under the IP platform of the truck reaches the plane mirror 3, and the plane mirror 3 reflects the light for the second time; the light reflected by the plane mirror 3 reaches the windshield 4, and the windshield 4 reflects the light for the third time; the light after three reflections enters the observation point 5 (human eye), and the human eye perceives the virtual image located on the virtual image plane 6 in front of the windshield 4. The head-up display body 1 and the free-form mirror 2 can be packaged and sunk under the IP platform, while the plane mirror 3 can be located on the IP platform and does not participate in the integration, which effectively reduces the problem of excessive size and does not block the driver's field of view, maintaining a good driving experience and safety.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
