Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted head-up displays, and more specifically, to a vehicle-mounted imaging VPA head-up display device. Background Art

[0002] Existing in-vehicle VPAs mainly include reflective VPAs, transmissive VPAs and augmented reality VPAs. Reflective VPAs are the most common form, which reflect information onto the front windshield through a projection system so that the driver can see the displayed information when looking forward. Transmissive VPAs use transparent displays to display information directly in front of the driver's line of sight. This method is usually equipped with advanced optical components to ensure that the information is clearly visible.

[0003] Existing vehicle-mounted transmissive VPAs generally project light onto a transparent display screen located on the inside of the windshield, but this method often results in a smaller projected image and poor environmental adaptability. When the front of the vehicle suddenly faces sunlight or car lights and other background light conditions change drastically, the image clarity and contrast of the VPA will be greatly reduced, seriously affecting the driver's viewing experience. Therefore, it needs to be improved. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a vehicle-mounted imaging VPA head-up display device, which has the advantage of high environmental adaptability.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vehicle-mounted imaging VPA head-up display device, comprising a transparent dust cover, a windshield is arranged above the transparent dust cover, a focusing area located at the upper left of the transparent dust cover is arranged on the left side of the windshield, an eye box is arranged on the left side of the focusing area, an upper shell is fixedly connected to the rear surface of the transparent dust cover, a bottom shell is fixedly installed on the rear surface of the upper shell, an LCD display is fixedly connected to the top of the right side of the outer surface of the bottom shell, a PGU is fixedly connected to the right surface of the LCD display, a No. 2 support frame is fixedly installed on the left side of the inner surface of the bottom shell, a large curved reflector is fixedly connected to the right surface of the No. 2 support frame, and a hinge block is fixedly connected to the front and rear sides of the right side of the inner cavity of the bottom shell, and a small curved reflector is movably sleeved on the inner surface of the hinge block.

[0009] As a preferred technical solution of the utility model, the outer surface of the driving shaft is fixedly sleeved with a driving gear located inside the mounting shell, and the outer surface of the driving gear is meshingly connected with a driven gear.

[0010] As a preferred technical solution of the utility model, the upper surface of the driven gear is fixedly connected with a threaded rod, the inner surfaces of the driven gear and the threaded rod are fixedly sleeved with a connecting shaft, and the connecting shaft is movably mounted on the inner surface of the mounting shell.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model is provided with a transparent dust cover, a small curved reflector, a large curved reflector, an LCD display screen and a windshield. The LCD display screen is a light source. After being reflected by the small curved reflector and the large curved reflector, the light is projected onto the windshield. The windshield reflects the light and forms a real image at a focus area position and is observed by the driver at the eye box position. This imaging method is not affected by changes in background light, greatly improving the environmental adaptability of imaging. Moreover, since the windshield is used for imaging, the problem that most images are small in previous imaging technologies is solved.

At the same time, the outer surface of the threaded rod is meshed with the outer surface of the No. 1 support frame. Therefore, the rotation of the threaded rod will drive the No. 1 support frame, so that the No. 1 support frame and the small curved reflector start to rotate together along the inner surface of the hinge block, thereby avoiding the problem of sunlight backflow damaging the LCD display screen.

[0026] The light from the LCD display screen 15 will be projected onto the reflective surface of the small curved reflector 4 and reflected by the small curved reflector 4. The reflected light will then be projected onto the reflective surface of the large curved reflector 9 and reflected by the large curved reflector 9. At this time, the light will pass through the shading plate 17 and be projected onto the outer surface of the windshield 16 and be reflected by the windshield 16. Finally, these light rays will form a real image with a size of 4.5 inches and a resolution of 720*1280 at the focusing area 14, and this real image will be observed at the eye box 13. The output end of PGU11 is electrically connected to the input end of the LCD display screen 15.

[0027] A shading plate 17 is disposed above the right side of the transparent dust cover 1 , and the shading plate 17 is rectangular in shape.

[0028] The shading plate 17 and the transparent dust cover 1 can be used to eliminate the influence of stray light on the VPA system.

[0029] Among them, a stray light protection cover 5 is fixedly installed on the upper side of the inner cavity of the bottom shell 8, a support column 6 is fixedly installed in the middle of the upper surface of the bottom shell 8, a mainboard 7 is fixedly connected to the upper surface of the support column 6, a radiator 12 is fixedly installed on the right side of the upper surface of the bottom shell 8, and PGU11 is fixedly installed inside the radiator 12.

[0030] The heat sink 12 can help the PGU 11 to dissipate heat.

[0031] Among them, a mounting plate 19 is fixedly installed on the right side of the bottom end of the inner cavity of the bottom shell 8, a mounting shell 20 is fixedly installed on the inner surface of the mounting plate 19, a driving motor 21 is fixedly installed on the lower surface of the mounting shell 20, and a driving shaft 22 is fixedly sleeved on the other end of the output shaft of the driving motor 21, and the top end of the driving shaft 22 passes through the mounting shell 20 and extends to the interior of the mounting shell 20.

[0032] When the driving motor 21 is running, the driving shaft 22 starts to rotate.

[0033] The outer surface of the driving shaft 22 is fixedly sleeved with a driving gear 23 located inside the mounting shell 20 , and the outer surface of the driving gear 23 is meshedly connected with a driven gear 24 .

[0034] When the driving gear 23 starts to rotate, the driven gear 24 starts to rotate under the meshing drive of the driving gear 23 .

[0035] The upper surface of the driven gear 24 is fixedly connected with a threaded rod 26 , and the inner surfaces of the driven gear 24 and the threaded rod 26 are fixedly sleeved with a connecting shaft 25 , which is movably mounted on the inner surface of the mounting shell 20 .

[0036] When the driven gear 24 starts to rotate, the connecting shaft 25 and the threaded rod 26 start to rotate along the inner surface of the mounting shell 20 .

[0037] The outer surface of the threaded rod 26 is meshedly connected with the first support frame 3 , and the right side of the upper surface of the first support frame 3 is fixedly mounted on the lower surface of the small curved reflector 4 .

[0038] When the threaded rod 26 starts to rotate, the first support frame 3 and the small curved reflector 4 will start to rotate along the inner surface of the hinge block 18 driven by the threaded rod 26 .

[0039] The working principle and use process of this utility model:

[0040] First, the driver installs the transparent dust cover 1 as a whole into the car. When the driver is ready to start driving, the driver first starts PGU11. The operation of PGU11 will cause the LCD display screen 15 to start lighting. When the light is projected onto the small curved reflector 4, the light will be reflected by the reflective surface of the small curved reflector 4 and projected onto the reflective surface of the large curved reflector 9. Similarly, the light will be reflected by the large curved reflector 9 and projected onto the windshield 16. At this time, the windshield 16 will also reflect these light rays. After being reflected by the windshield 16, these light rays will form a real image at the focus area 14 and be observed by the eye box 13, thereby improving the environmental adaptability of imaging.

[0041] When the sunlight backflow phenomenon occurs, the driver starts the drive motor 21. As the drive motor 21 runs, the drive shaft 22 and the driving gear 23 begin to rotate, and the rotation of the driving gear 23 drives the driven gear 24, so that the driven gear 24, the connecting shaft 25 and the threaded rod 26 all begin to rotate along the inner surface of the mounting shell 20. At the same time, the rotation of the threaded rod 26 drives the No. 1 support frame 3, so that the No. 1 support frame 3 and the small curved reflector 4 begin to rotate along the inner surface of the hinge block 18. At this time, the backflowing sunlight will not directly shine on the LCD display screen 15 after being reflected by the large curved reflector 9 and the small curved reflector 4, thereby avoiding the situation where the LCD display screen 15 is damaged by the backflow of sunlight.
