Abstract

The invention relates to the technical field of new energy automobile charging piles, in particular to an anti-creeping charging pile based on a new energy automobile and an anti-creeping method thereof. The anti-creeping charging pile comprises a charging pile body and a winding box, the charging pile body is provided with a power supply set, the winding box is fixed to the bottom of the charging pile body, a wire outlet is formed in one side of the winding box, a charging cable is arranged in the winding box, one end of the charging cable is electrically connected with the power supply set, a winding mechanism used for winding the charging cable is arranged in the middle of the charging cable, a blocking mechanism is arranged at the position, close to the cable outlet, of the charging cable, and when the charging cable moves to the external side of the cable outlet, the blocking mechanism is used for blocking the bulge of the charging cable; and according to the scheme, the gun head of a charging gun is shielded and protected through a protection mechanism, and the cable bulge is blocked through the blocking mechanism, so that the charging cable is prevented from being directly pulled out, and the situation that the charging cable is damaged and leaks electricity during use is prevented, and the safety of a user is protected.

Description

technical field [0001] The invention relates to the field of new energy vehicle charging piles, in particular to a new energy vehicle-based leakage-proof charging pile and a leakage-proof method thereof. Background technique [0002] The function of the charging pile is similar to that of the fuel dispenser in the gas station. It can be fixed on the ground or on the wall, and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential area parking lots or charging stations. Charge all models of electric vehicles. [0003] Some invention patents related to new energy vehicle charging piles are disclosed in the prior art. The Chinese patent application number is 201811308330.1, which discloses a charging pile for new energy vehicles that prevents leakage and has the function of washing the wheels, and relates to the field of new energy vehicle charging technology. , specifically a base and a bottom plate, a housing is fixed abov...

Problems solved by technology

[0006] In order to achieve the above purpose, the technical solution adopted by the present invention is: a leakage-proof charging pile based on new energy vehicles, including a charging pile body and a winding box, the charging pile body has a power supply group, and the winding box is fixed on At the bottom of the charging pile body, a charging cable is arranged inside the winding box, one end of the charging cable is circularly rotated and energized with the surface of the cylindrical battery core, and an outlet is opened on one side of the winding box, and the charging cable One end of the cable is electrically connected to the power supply group. The middle part of the charging cable is provided with a winding mechanism for winding the charging cable. The charging cable is provided with a blocking mechanism near the outlet. When the charging cable When the cable moves to the outside of the outlet, the blocking mechanism is used to block the bulge of the charging cable; the other end of the charging cable penetrates the outlet and is extended to fix the charging gun. The side wall of the charging pile body There is an installation slot on the top, and the charging gun is provided with a clamping mechanism, which is used to clamp the charging gun inside the installation slot. When inside the installation groove, the protection mechanism is used to seal the opening of the installation groove. When the charging gun is separated from the installation groove, the protection mechanism is used to shield and protect the tip of the charging gun. A smoke sensor and a miniature fire extinguisher are fixed inside the box, and the smoke sensor is electrically connected to the miniature fire extinguisher; when working, the connection between the charging gun and the charging pile in the prior art is only simply snapped and fixed. In the process of taking it, the charging gun is easily wetted by rain, causing leakage accidents; and most of the existing charging cables are simply rolled up inside the charging pile. After the cable is used for a long time, the surface of the cable is prone to appear Bulge, if there is a bulge on the surface of the cable, after long-term drag and friction, if the bulge is not maintained in time, it will be easily damaged and cause more serious leakage accidents. This technical solution can solve the above problems. The specific working method As follows, when using in rainy days, first manually cancel the positioning of the charging gun by the clamping mechanism, and then take out the charging gun. At this time, the protective mechanism automatically shields and protects the tip of the charging gun to prevent rainwater from splashing on the tip of the charging gun. If there is a bulge on the charging cable, it will block the bulge of the cable through the blocking mechanism. Use When the operator finds that the charging cable cannot be pulled out, he can know in time that the charging cable cannot be used, which is convenient for the maintenance personnel to come and repair in time, preventing the charging cable from being pulled out directly, causing damage and leakage during use, and further protecting the user. For the safety of the operator, after use, insert the charging gun into the installation slot, clamp and fix the charging gun through the clamping mechanism, and seal the opening of the installation slot through the protection mechanism to prevent rainwater from entering the installation slot, which is beneficial Keep the inside of the installation slot dry, protect the tip of the charging gun, and automatically rewind the charging cable through the rewinding mechanism to avoid manual direct contact with the charging cable, which may cause leakage. The charging cable inside the rewinding box When a fire occurs due to an electric leakage, the smoke sense The responder can sense the smoke inside the winding box in time and drive the miniature fire extinguisher to extinguish the fire inside the winding box
