Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision of charging piles, and in particular to a protective device for a charging pile. Background Art

[0002] A car charging pile is a charging device that provides power for electric vehicles. Its function is similar to that of a gas pump in a gas station. The core parts of the charging pile include the pile body, charging module, display screen, connecting cables, account management module and safety protection device. Its working principle is to combine the power supply, converter and output device to change the voltage from low to high, and finally realize charging of electric vehicles.

[0003] A sponge board is generally provided at the height of the vehicle body on the outside of the charging pile body. The sponge board can reduce the damage caused by the collision between the charging pile body and the vehicle body. The existing sponge board is generally glued to the outside of the charging pile body with glue. When hit, the sponge board will be damaged by collision and needs to be replaced in time. However, the glue bonding and fixing form requires the installer to clean the residual sponge debris on the surface of the charging pile, so as to avoid the debris affecting the stability of the connection of the newly replaced sponge board. However, the process of removing glue and debris consumes the time of sponge board installation. In order to achieve rapid installation of the sponge board, a new type of charging pile protection device is needed. Utility Model Content
