Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the explanatory text.

[0042] Such as Figure 1-13As shown, the present invention provides a DC charging pile with automatic tripping protection of the charging interface, including: a charging pile body 100 and a charging gun head 200 . The input terminal of the charging pile body 100 is connected to the three-phase power supply, the charging gun head 200 is connected to the output terminal of the charging pile body 100, and a cylindrical plug-in terminal 210 is telescopically set on the end of the charging gun head 200, normally state, the plug end 210 is in a protruding position, and the plug end 210 is plugged into the car charging pin interface to charge the battery pack. When a fault occurs or the battery pack is in the floating charge state for a long time, the control plug end 210 is ...

Abstract

The invention discloses a DC charging column having a charging interface with automatic tripping protection, being characterized in that a plug end is axially telescopically arranged on the end of thecharging gun head; a through hole is axially pierced through the center of the plug end cylinder; a first channel is arranged on the periphery of the through hole; a pair of half cross-sectional bodies are arranged in the through hole; a second channel is arranged on the periphery of the half cross-sectional bodies, and the first channel is butted with the second channel to form an electrically conductive plug hole; a half-conical cavity is axially formed in the cross section of the half-section body, and a conical cylinder is telescopically arranged in the semi-conical cavity on the left andright sides; a pair of cavity channels are axially symmetrically arranged on the inner side end of the plug end; a limiting cavity is arranged on the outer side end of the cavity channel; the inner side end of the conical cylinder is connected with the telescopic end of a telescopic mechanism; a pair of branch linkage bars are symmetrically arranged on both sides of the telescopic end; and the ends of the branch linkage bars are protruded and provided with linkage heads, and the linkage heads restrict movement in the limiting cavity. The DC charging column having a charging interface with automatic tripping protection solves the technical problem that the DC charging column does not have a mechanical overcurrent protection mechanism.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a DC charging pile for automatic trip protection of a charging interface. Background technique [0002] The function of the charging pile is similar to the refueling machine in the gas station. It can be fixed on the ground or 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. The input end of the charging pile is directly connected to the AC grid, and the output end is equipped with a charging plug for charging the electric vehicle. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding charging methods, charging time, and cost...
