Electronic lock for charging socket, charging socket and electric vehicle

Abstract

The invention relates to an electronic lock for a charging socket, a charging socket and an electric vehicle. The electric vehicle comprises a vehicle body and a charging socket mounted on the vehiclebody, the charging socket comprises a socket body and an electronic lock mounted and fixed on the socket body, the electronic lock comprises a housing, the locking pin and the pulling rope capable ofretracting the locking pin when pulled, the outer side of the housing is provided with a reversing wheel set for the pulling rope to bypass to change the pulling direction of the pulling rope, By setting the reversing wheel set, A pull rope is reversed by a reversing wheel set, The invention avoids the problem of large frictional force caused by the friction of the side wall of the pulling rope when the pulling rope tilts and pulls the pulling rope, so that the user can easily pull the pulling rope in any direction, and the design of the pulling rope in any direction can greatly facilitate the use of the user when the electronic lock is installed in a narrow and inconvenient environment.

Description

technical field [0001] The invention relates to an electronic lock for a charging socket, a charging socket and an electric vehicle. Background technique [0002] When charging an electric vehicle, it is necessary to insert the charging gun with the cable into the charging socket installed on the electric vehicle, and then turn on the power supply after it is plugged in place to realize charging. After charging, pull out the charging gun from the charging socket That's it. In order to prevent safety accidents caused by the charging gun being pulled out by mistake during the charging process, a locking device needs to be provided between the charging socket and the charging gun. At present, an electronic lock is generally installed on the charging socket, and the lock pin of the electronic lock is electrically controlled to be inserted into and disengaged from the keyhole on the charging gun to realize the locking and unlocking of the charging gun and the charging socket.

Problems solved by technology

[0003] At present, the common manual unlocking mechanism on the market uses a pull cord to pull the lock pin to unlock. The pull cord is generally drawn directly from the tail of the electronic lock. When manual unlocking is required, the pull cord must be pulled backward along the moving direction of the electronic lock pin. The space where the electronic lock is installed on the charging socket is narrow, and it is very inconvenient to pull the wire backwards. If the operator pulls the wire from the insertion direction of the vertical lock pin, there will be another problem, that is, the direction of the wire and the wire are inside the housing. A section of the pull cord forms a bend. Since there is generally a sealing structure between the pull cord and the housing, the friction force is relatively large. The friction between them is greater, it is very difficult to pull the wire, and it may even cause the wire to be broken, which is very inconvenient
