TECHNICAL FIELD
[0001] The utility model belongs to waterproof plug technical field, concretely is a kind of electric vehicle charging plug with waterproof function. BACKGROUND
[0002] The charging plug on the charger of most battery cars (i.e. electric bicycles) usually has three pin holes, which are matched with the charging interface pins of the electric vehicle for charging. If the charging head is exposed for a long time, the waterproof material may age or be damaged, and the waterproof performance may decrease. Especially in a humid or rainy environment, moisture may penetrate into the charging head, damaging the circuit or causing a short circuit. The charger of the electric vehicle is usually placed in the trunk by most people, and raincoats and other items are usually placed in the trunk as well. Especially on rainy days, the used raincoat may carry rainwater, which may easily enter the pin holes of the charging plug, causing damage to the pin holes.
[0003] According to the authorized publication No. CN208508109U, a waterproof plug for electric bicycles is disclosed, which is provided with a waterproof shell and a rotating plate to improve the sealing of the plug, prevent water or water vapor from the outside from entering the plug, damage the plug, and reduce the service life of the plug. The plug pin has an insulation and anti-electric shock function, effectively preventing people from being electrocuted by touching the plug pin, and has high safety performance. At the same time, the compression spring allows the insulation sleeve to freely expand and contract, providing great convenience to people. The plug is fixedly connected to the socket through the cooperation of the protrusion and the cavity, preventing the plug from being loosely connected to the socket and causing a leakage.
[0004] According to the authorized publication No. CN220209416U, a charging plug structure with waterproof function is disclosed, which comprises a protective cover, a clamping mechanism, a connecting side plate, a spring, a fixed block, a sliding rod, a hinge rod, a clamping rod and a pressing block. The protective cover can be easily installed at the front end of the plug shell to cover the pin holes, preventing rainwater carried in the raincoat from entering the pin holes and causing damage to the charging plug body. At the same time, the protective cover can be easily removed from the front end of the plug shell.
[0005] The above-mentioned patent achieves a certain waterproof effect, but the waterproof effect required parts are exposed, which may be damaged. If the charging head is exposed for a long time, the waterproof material may age or be damaged, and the waterproof performance may decrease. Especially in a humid or rainy environment, moisture may penetrate into the charging head, damaging the circuit or causing a short circuit. Therefore, we propose a charging plug for electric vehicles with waterproof function. UTILITY MODEL CONTENTS
