Moisture-proof charger for electric vehicle

Abstract

The invention discloses an electric vehicle moistureproof charger, and belongs to the technical field of chargers. The charger comprises a charger shell, and two side plates of the charger shell are provided with a plurality of heat dissipation holes; a moistureproof mechanism is installed at the position, close to the heat dissipation holes, in the charger shell, and the moistureproof mechanism comprises two sliding frames. Baffles are installed on the sliding frames, the baffles and the heat dissipation holes are arranged in a staggered mode and matched in size, and when moisture preventionis needed, the baffles cover the heat dissipation holes by moving the sliding frames. The movable moisture-proof mechanism is installed in the charger shell, and the moisture-proof mechanism seals theheat dissipation holes to prevent moisture and water; during normal use, the holes of the heat dissipation holes are in a communicated state to dissipate heat, and when moisture prevention is needed,the moisture-proof mechanism covers the heat dissipation holes through sliding to prevent moisture; through the moisture-proof mechanism, normal heat dissipation of the charger is not affected, and amoisture-proof effect can be achieved as required.

Description

technical field [0001] The invention relates to the technical field of chargers, in particular to a moisture-proof charger for electric vehicles. Background technique [0002] The electric vehicle charger is a charging device specially configured for the battery of the electric bicycle! Classification of chargers: with and without power frequency (50 Hz) transformers, they can be divided into two categories. Freight three-wheel chargers generally use chargers with power frequency transformers, which are large in size, heavy in weight, and consume electricity, but they are reliable and cheap; electric bicycles and electric motorcycles use so-called switching power supply chargers, which save electricity and have high efficiency. The current switching power supply charger is divided into two categories: half bridge type and single excitation type, and the single excitation type is divided into two types: forward type and flyback type. The half-bridge type has high cost and g...
