[0002] With the improvement of people's living standards, electric vehicles are used more and more frequently in people's daily life. Since electric vehicles convert electrical energy into kinetic energy, people need to charge electric vehicles frequently. Electric vehicle chargers are a charging device specially configured for electric vehicle batteries.

[0003] The existing charger is generally from both ends of the air inlet and outlet, without any waterproof measures, so that rainwater can easily enter the charger shell from the side of the charger when charging in rainy weather. Although the side door of the charger has a certain rainproof effect, there is still a probability of rainwater entering from the side. In order to reduce the possibility of rainwater entering the charger shell, and to avoid foreign matter entering the air vent and causing the air vent to be blocked, affecting the ventilation and heat dissipation effect, the present application aims to provide a rainproof charger shell for electric vehicles.

The slot b inner cavity is provided with a grid b inserted and matched with the grid a. The both ends of the grid b inner cavity are slidably installed with a sealing element. When the bottom shell and the top shell are snap-fit, the sealing element moves to the ventilation port to block and close the ventilation port, preventing water overflow from the bottom into the shell when the water depth is too deep. The sealing element can clean the foreign matter in the grid a and the grid b during movement, preventing the grid a or the grid b from being blocked and affecting the ventilation and cooling of the charger.

[0011] As a further improvement of the technical solution, the sealing piece divides the space of the ventilation cavity, so that the ventilation cavity becomes a long and narrow airflow channel, the airflow velocity is enhanced, and the ventilation and cooling effect of the charger is enhanced, and in order to further guarantee the air inlet and outlet effect of the ventilation opening, support feet are arranged at the four corners of the lower surface of the bottom shell.
