Abstract: The present invention relates to a structure for a device cover which is manufactured by forming a decoration layer on a plastic film, injecting the same in a mold, and injecting plastic resin. The structure for a cover improves a molding property by using PC, PVC, or ABS films with relatively low thermal deformation temperature and weak restoring force instead of a PET film with strong restoring force after forming, and improves a film peeling problem due to the restoring force of the film after the molding. In addition, the device cover is manufactured by a molding method due to film insert injection. Technically, a decoration layer, especially a metal deposition layer or a translucent printing layer is arranged on a film which is not directly exposed to injection resin to be not directly exposed to thermal and pressure atmospheres or environments due to the injection resin. Therefore, the present invention reduces a lot of printing for decoration protection to greatly reduce costs. In a PET/PC/PET composite sheet 3D heat-forming method which is another cover structure of the present invention, by adding an UV blocking function, the present invention can improve a yellowing problem caused by ultraviolet rays of the PC forming a composite sheet.

Preferably, almost all parking spaces are designed to have or have in the future the charging adapters (5015). For example, the number of electric vehicles that can be charged at the same time is 60 units, but parking spaces with the charging adapters (5015) can be 500 units. In this case, the parking spaces allow internal combustion engine vehicles and electric vehicles to be arbitrarily parked without the distinction therebetween. Even in the case of an electric vehicle, even if the same is fully charged, the same is not required to be removed from the parking spaces. In addition, designated parking spaces can be set, and even if drivers use internal combustion engine vehicles, or change the same to electric vehicle in the future, the drivers can use the same parking space without any inconvenience.
