AI Technical Summary

Technical Problem

The existing electric vehicle battery interface lacks a locking function, which makes it easy to come loose unintentionally, affecting the charging effect and potentially causing safety accidents.

Method used

A quick-change interface for electric vehicle batteries designed to prevent mis-insertion uses a structure of insert blocks, locking blocks, elastic elements, and magnets. The locking function is achieved through the cooperation of the insert blocks and locking blocks, and a detector and an alarm are provided to detect abnormalities and issue an alarm.

Benefits of technology

It effectively prevents the interface from becoming loose or falling off, ensuring the safety and stability of the charging process, while also increasing applicability and reminding users to take measures to avoid accidents in abnormal situations.

Abstract

The utility model relates to the technical field of interfaces, in particular to an anti-misplug electric vehicle battery quick-change interface, which comprises a first interface, a protective cover, a second interface, a connecting wire, an insertion block, a mounting seat, a guide rod and a protective shell, the first connector is provided with an insertion block, the second connector is provided with a protection shell and an installation base, and the installation base is fixedly connected with two guide rods. The second interface is pushed into the first interface, the insertion block immediately extrudes the clamping block to move, the clamping block drives the two sliding plates and the connecting plate to move downwards to extrude the elastic piece, and when the clamping block is aligned with an opening in the insertion block, the elastic piece rebounds to drive the clamping block to move upwards to be clamped into the insertion block, so that the first interface and the second interface are locked. The interface is prevented from loosening or falling off due to accidental touch or other external forces, and the safety and stability of the charging process are guaranteed.
