Multi-stage protection and reminding device for new energy vehicle charging pile

Abstract

The invention relates to the technical field of new energy, and discloses a multi-stage protection and reminding device for a new energy vehicle charging pile. The device comprises a charging column,an adjusting apparatus comprises: arc-shaped metal sheets, arc-shaped tables, a metal sheet-free area, elastic balls and insulating areas, a metal hemisphere is arranged at the upper end of a swing rod, a first spring is arranged between the swing rod and a rotary disc, the left end at the upper part of a half I-shaped rod is connected to a piston, and the lower part of the piston is connected toa heat-absorbing plate. Expanded gas pushes the piston to move backwards, the piston drives the rotary disc to move backwards through the half I-shaped rod, the rotating disc drives the swing rod to rotate in the adjusting apparatus, the swing rod is divided into four grades in the adjusting apparatus along with the difference of temperature in the charging device, and the effects of cooling, current limiting, warning and circuit breaking are achieved at a time through the structure respectively, therefore the problem that the existing new energy vehicle charging pile does not have the multi-stage protection function is solved.

Description

technical field [0001] The invention relates to the field of new energy technology, in particular to a multi-level protection and reminder device for charging piles of new energy vehicles. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as the power source, the comprehensive vehicle power control and advanced technology in driving, and the formation of advanced technical principles, new technologies, and new structures. Today, human beings have once again come to traffic. At the crossroads of energy and power system transformation, the third transformation will replace petroleum and internal combustion engines with electricity and power batteries, bringing mankind into the era of clean energy. We boldly predict that the third transformation of transportation energy and power systems will drive the Asian economy The rapid rise of China has enabled Asia to replace the United States as the engine of the world economy.
