[0022] like Figure 1-2 As shown, a projection device for a bus stop display screen includes an information box 1, with symmetrically distributed transparent panels 2 on the front side of the information box 1, and also includes a projection component and an energy conversion component. The projection component is located inside the information box 1, and the energy conversion component is located on the information box 1.

[0023] like Figure 1-4 As shown, to enhance the information viewing experience for passengers, the projection assembly includes a projection panel 3 fixedly installed on the inner wall of the information box 1. An inner panel 4 is fixedly connected between the inner walls of the information box 1. Symmetrically distributed ultra-short-throw projectors 5 are fixedly connected to the top of the inner panel 4. An optimized viewing mechanism for adjusting visibility is provided on the front side of the projection panel 3. The optimized viewing mechanism includes L-shaped guide rods 9 fixedly installed on the inner wall of the information box 1, arranged symmetrically in pairs. A slider 10 slides horizontally on the guide rods 9. Electrochromic glass 11 is fixedly connected to the outer wall of the slider 10. Two sets of electrochromic glass 11 are provided. A top plate 12 is fixedly installed on the top wall inside the information box 1. A servo motor 13 is fixedly installed on the outer wall of the top plate 12. A gear 14 is fixedly connected to the output end of the servo motor 13. A rack 15 that meshes with the gear 14 is fixedly connected to the outer wall of the electrochromic glass 11. There are two sets of racks 15, which are distributed on the upper and lower sides of the gear 14. By rotating the gear 14, the two racks 15 can drive the two sets of electrochromic glass 11 to drive the slider 10 to slide on the guide rod 9. The two electrochromic glass 11 move closer to each other, which can reduce the impact of sunlight on the visibility of the projection panel.

[0024] like Figure 1-4 As shown, in order to solve the problem of not being able to view information during power outages, the energy conversion components include a photovoltaic panel 6 located on top of the information box 1, an inverter 7 fixedly installed inside the information box 1 and electrically connected to the photovoltaic panel 6, a battery 8 fixedly installed on the inner wall of the information box 1 and electrically connected to the inverter 7, a turntable 16 rotatably connected to the top wall of the information box 1, the photovoltaic panel 6 being fixedly installed on the top wall of the turntable 16, mounting holes 17 on both sides of the turntable 16, and a ring of positioning grooves 18 on the top wall of the information box 1, which correspond to the mounting holes 17. The photovoltaic panel 6 can be adjusted at the corresponding angle according to the direction of the platform, and the light energy can be converted into electrical energy to supply power to the corresponding equipment, thus avoiding the equipment from not displaying information due to power outages.

[0025] Among them, the ultra-short throw projector 5, the electrochromic glass 11, and the servo motor 13 are electrically connected to the battery 8.

[0026] In practical use, the ultra-short-throw projector 5 projects the corresponding information onto the projection panel 3 for passengers to find information. The angle of the photovoltaic panel 6 on the top of the information box 1 is adjusted according to the direction of the platform to make it easier to align with the sunlight. Then, it is screwed into the mounting hole 17 and the corresponding positioning groove 18 by bolts. The inverter 7 converts the DC power generated by the photovoltaic panel 6 into AC power and stores it through the battery 8 to supply power to the corresponding equipment, avoiding the equipment from not displaying information due to power outages. If the sunlight intensity is too high, the servo motor 13 is turned on. The rotation of the gear 14 causes the two racks 15 to drive the two sets of electrochromic glass 11 to drive the slider 10 to slide on the guide rod 9. The two electrochromic glass 11 move closer to each other and open, which reduces the impact of sunlight on the visibility of the projection panel and makes it easier for passengers to observe the corresponding travel information.
