Description

Technical Field

[0001] The utility model relates to the technical field of charging pile screen protection, and in particular to a protection device for a charging pile screen. Background Art

[0002] With the continuous development of new energy, electric vehicles are gradually becoming popular in society. As electric vehicles become increasingly popular, charging piles for charging electric vehicles have also come into people's view. The popularity of charging piles has facilitated the owners of electric vehicles, so that electric vehicles are no longer troubled by insufficient power. The billing method of charging piles mainly adopts the method of time-based, electricity-based and amount-based charging to charge electric vehicles. Regardless of the billing method, it is necessary to cooperate with the display screen on the charging pile to display the relevant values, so that the electric car owner can understand the charging status through the display screen and then smoothly pay the amount spent on charging. Therefore, the protection of the charging pile screen is also inevitably important.

[0003] The protective devices of existing charging pile screens are mostly driven to open and close by motors or other power mechanisms at the same time. Even if there are a few manually driven protective structures, manual operation is required for opening and closing. Not only is the operation troublesome, but when the personnel forget to close it, the protective device loses its original protective function.

[0004] Therefore, it is necessary to provide a protective device for a charging pile screen to solve the above technical problems. Utility Model Content
