New energy automobile charging device with high security protection performance

Abstract

The invention discloses a new energy automobile charging device with high security protection performance. The charging device comprises a charging pile formed by a propulsion part and a power supply part, and a charging gun. The propulsion part is fixedly arranged in an upper position of the left side of the power supply device. A propulsion sliding groove is arranged in the end face of the bottom end of the propulsion part. A first threaded rod which left-right extends is arranged in the propulsion sliding groove. The left side end of the first threaded rod is connected with a first motor. The right side end of the first threaded rod is in rotatable matched connection with the inner wall of the right side of the propulsion sliding groove. A clamping propulsion block which is in threaded matched connection with the first threaded rod is arranged on the first threaded rod. A push-press rod which extends towards the right side is arranged on the right side end face of the clamping propulsion block under the first threaded rod. A slope push-press head is arranged at the tail end of the right side of the push-press rod. A first sliding cavity which longitudinally extends is arranged in the power supply part. A sink groove is arranged in the inner base wall of the first sliding cavity. The charging device is simple in structure, capable of achieving automatic charging and insertion connection, and capable of automatically controlling exposure and hidden work of a power supply insertion needle, so working efficiency and safety are improved.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle charging, in particular to a new energy vehicle charging device with strong safety protection performance. Background technique [0002] With the emergence of electric vehicles, the use of charging piles for electric vehicles has increased. When users use existing electric vehicle charging piles to charge electric vehicles, they directly insert the charging plug into the socket for charging. Electric vehicle charging piles can provide convenient and fast charging functions for car owners in parking lots, residential areas, highway rest areas, etc., provide strong support for the long-lasting battery life of electric vehicles, and completely solve the problem of insufficient battery life of electric vehicles. However, in the existing technology, ordinary car charging plugs are prone to arcing due to the influence of voltage during the plugging and unplugging process. The generation of ar...

Problems solved by technology

However, in the existing technology, ordinary car charging plugs are prone to arcing due to the influence of voltage during the plugging and unplugging process, and the generation of arcs is likely to cause electric shock to users, which has certain potential dangers to users, and has poor plugging stability. , easy to loosen, resulting in poor contact, and because there is a large current flowing through the socket, the charging plug is easily damaged
