Problems solved by technology

[0003] When the charging cabinet is charging the electric vehicle, the operator needs to insert the charging gun into the charging interface of the electric vehicle. If the operator inserts the charging gun into the charging interface, there will be an unstable connection, which will lead to other external factors. The phenomenon that the charging gun is separated from the charging device will cause the charging device to not be fully charged in time, which will cause the user to be unable to use it later.
[0004] The contact resistance between the pin in the charging gun and the conductive sleeve in the charging interface will increase, which will increase the heat output from the charging gun and the charging interface. This operation for a long time will easily burn out the charging gun and the charging interface. , it is also easy to cause damage to the battery of the electric vehicle

Abstract

The invention provides a connecting device for a charging gun and a charging interface, and belongs to the technical field of electric vehicle charging. The connecting device for the charging gun andthe charging interface comprises a guide head arranged on the charging gun and a clamping assembly arranged on the charging interface, the charging gun and the guide head are connected through a flexible joint, the guide head comprises a horn clamping block, a charging base, a turntable, a pin shaft I, a pin shaft II, a connecting rod I, a connecting rod II, a motor I and a guide block, and the clamping assembly comprises a notch gear ring, a gear and a motor II. The connecting device has the advantage that the charging gun and the charging interface can be connected more firmly.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle charging, and relates to a charging gun and a charging interface, in particular to a connection device between the charging gun and the charging interface. Background technique [0002] Electric vehicles are powered by on-board power supplies. Existing electric vehicles etc. use the charging gun on the charging cabinet (charging pile) to charge, and the charging gun is inserted into the charging interface on the electric vehicle, and the charging cabinet just can charge the electric vehicle. [0003] When the charging cabinet is charging the electric vehicle, the operator needs to insert the charging gun into the charging interface of the electric vehicle. If the operator inserts the charging gun into the charging interface, there will be an unstable connection, which will lead to other external factors. It causes the phenomenon that the charging gun is separated from the charging equipm...
