Description

Technical Field

[0001] The utility model relates to an electronic map device, in particular to a waterproof and anti-aging basic public service facility electronic map device. Background Art

[0002] Electronic maps, or digital maps, are maps that are stored and accessed digitally using computer technology. Electronic maps can output geographic locations at any scale and in any range. They are very easy to modify, which shortens the time it takes to draw a map. They can be easily combined with other information sources such as satellite images and aerial photos to generate new types of maps. The information recorded in digital maps can be used to derive new data. For example, the contour lines on the map represent landforms, but it is difficult for non-professionals to understand them. The contour lines and elevation points on the electronic map can be used to generate digital elevation models, which can express the surface undulations in digital form and can intuitively and three-dimensionally express the landforms.

[0003] When electronic maps are used outdoors, such as in public transportation or public places, they are easily eroded by rain and sunlight from the external environment, which accelerates aging and damage, affecting their service life. Although existing electronic maps are protected by a shell when used outdoors, the shell has a simple structure and does not provide good protection for electronic maps. Under the impact of heavy rain and strong sunlight, rain can still enter the electronic map through the gaps in the shell, and ultraviolet rays can also penetrate the shell and irradiate the electronic map, causing the internal components to age or be damaged, shortening their service life.
