Description

Technical Field

[0001] The utility model relates to the technical field of display screens, and in particular to a folding display screen for ETC. Background Art

[0002] With the rapid development of intelligent transportation systems, the Electronic Toll Collection (ETC) system has become one of the main ways of highway toll collection, greatly improving road traffic efficiency and reducing traffic congestion.

[0003] In the current context of the widespread application of electronic toll collection systems on highways, traditional fixed ETC displays have gradually revealed some limitations and shortcomings due to their non-foldable nature. Although these displays have played an important role in simplifying the toll collection process and accelerating vehicle traffic, their design and functions can no longer fully meet the growing needs of modern intelligent transportation systems.

[0004] First, fixed display screens tend to take up a lot of space due to their large size and fixed shape, which is a big challenge for toll station design, especially in areas with limited space or compact layout. They not only affect the overall aesthetics of the toll station, but may also limit the layout and optimization of other facilities.

[0005] Secondly, the non-folding structure limits the flexibility of information display. In practical applications, in addition to displaying basic information such as toll amount and account balance, the ETC system should also be able to display more dynamic information as needed, such as real-time road conditions and weather warnings. The fixed screen size is fixed, making it difficult to effectively integrate multiple information on the same interface, reducing the efficiency and richness of information transmission.

[0006] Furthermore, fixed display screens are prone to poor viewing angles when faced with differences in vehicle models and window heights, making it difficult for drivers to read, and even requiring them to stop the car to adjust the angle for viewing. This, to a certain extent, goes against the original intention of the ETC system for fast passage.

[0007] In order to solve the above technical problems, the utility model designs a folding display screen for ETC. Utility Model Content

[0008] The utility model provides a folding display screen for ETC, aiming to solve the problem that the existing ETC screen is fixed and occupies a large space and cannot adjust the angle. The technical solution is as follows:

[0009] A folding display screen for ETC comprises: an upper side frame, a lower side frame, a middle upper frame, a middle lower frame, an upper support rod, a lower support rod and a display module; the upper side frame and the lower side frame are rotatably connected, the middle upper frame and the middle lower frame are rotatably connected, the upper support rod is mounted on the upper side frame and the middle upper frame, the lower support rod is mounted on the lower side frame and the middle lower frame, the upper side frame, the lower side frame, the middle upper frame and the middle lower frame are all equipped with a power supply control module, and the display module is detachably mounted on the upper side frame and the lower side frame.

[0010] Based on the above technical solution, a bracket is installed on the intermediate mounting frame, and screw holes are provided on the bracket.

[0011] Based on the above technical solution, the display assembly block includes a display light board and end covers, and the end covers are installed at both ends of the display light board.
