In particular, in international metropolitan areas, the problem of air pollution due to fuel-powered vehicles is more pronounced. In order to protect the environment, the atmospheric pollution is reduced. Various countries are dedicated to developing electric vehicles because electric vehicles directly use electric energy without discharging any pollutants.
Electric vehicles need to be charged frequently, and in order to facilitate charging of electric vehicles, electric vehicles are currently generally charged through a charging pile having a charging plug (or called a charging gun). When charging, the charging plug is directly inserted into the charging socket of the electric automobile, so that the electric automobile can be charged, and the charging is very convenient.
According to national standard requirements, in order to ensure charging safety when charging an electric vehicle, a charging plug must be reliably locked to a charging socket of the electric vehicle during charging, and cannot be pulled out from the charging socket of the electric vehicle. In the prior art, a mechanical locking device and an electronic safety device (or referred to as an electronic lock) are generally mounted on the charging plug. When charging, the mechanical locking device on the charging plug is locked with the charging socket on the electric automobile, and the electronic safety device keeps the mechanical locking device in a locking state so as to prevent the mechanical locking device from being unlocked accidentally.
In the prior art, an electronic safety device on a charging plug generally adopts an electromagnet, and reliable locking of a mechanical locking device is realized by utilizing linear motion of the electromagnet.
