Alternating current and direct current dual-purpose self-service charging system

Abstract

The invention discloses an alternating current and direct current dual-purpose self-service charging system which comprises a base, a box body is fixedly installed on the upper surface of the base, an alternating current and direct current dual-purpose power supply box is arranged in an inner cavity of the box body, a linear motor is further arranged in the inner cavity of the box body, a sliding rail is fixedly installed on the bottom face of the inner cavity of the box body, and a sliding block is installed on the sliding rail. The sliding block can slide in the length direction of the sliding rail, the end face of one end of the sliding block is fixedly connected with a telescopic rod of the linear motor, the end face of the other end of the sliding block corresponds to a pressing type spring switch on the left side face of the inner cavity of the box body, a rotating shaft is installed in the inner cavity of the box body, and a take-up roller is fixedly installed on the rotating shaft. A gear is further fixedly installed on the rotating shaft, two charging plug installation bases are fixedly installed on the right side face of the box body, and charging plugs are installed on the two charging plug installation bases. The system has the advantage that the self-service charging function can be achieved.

Description

Technical field [0001] The present invention relates to AC-DC charging technology, and more particularly a DC self-charging system cross. Background technique [0002] With green living, low carbon travel concept gaining in popularity, green energy-efficient new energy vehicles gradually into people's lives. At this stage, new energy electric vehicles has been widely used. In order to keep smooth travel, must be provided with a respective electric vehicle charging system, the existing system can be divided into a charging DC charging mode, an alternating AC and DC charging mode and the charging mode. The charging system bears tasks supplemental power electric vehicles, and control the charging process of the charging abnormal protection. [0003] AC current charging system to the charging system mostly, but less than normal DC charging system, AC-DC charging system less. With the improvement of people's living standards, the electric car models are more and more integrated AC and...

Problems solved by technology

However, there are still problems in the safety performance of the existing AC and DC self-service charging systems;

[0005] First of all, the existing AC-DC dual-purpose self-service charging system is also exposed to the outside of the charging line when it is not in use. Even if the charging line is built into some systems, it is easy to be pulled out, and there is a big safety hazard;

[0006] Secondly, the existing AC and DC dual-purpose self-service charging system will still be powered on when not in use, which not only has the risk of leakage, but also accelerates the aging of the internal electronic components of the charging system after being powered on for a long time, thereby affecting its use. life
