Abstract

The invention discloses a motor locking device comprising a housing, and a tooth bar, a gear wheel, a push rod and a drive mechanism arranged in the housing; the tooth bar and the gear wheel are mutually engaged; the tooth bar is fixed on the push rod; the drive mechanism is connected with the gear wheel and used for driving the gear wheel to rotate; the housing is provided with an opening that allows two ends of the push rod to freely extend in and out. The invention also discloses an electric vehicle DC charging connector comprising a connector casing, a lock bar arranged in the connector casing, a microswitch and the motor locking device; the lock bar is movably connected with the inner wall of the connector casing, and can rotate with respect to a movable joint. An electromagnet has insufficient sucking force under a vibration state, thus causing damages on human body by accidently loosening; a stepping motor with a low power (1-2W) is employed, and the power thereof only equals to10% of that of the electromagnet, thus greatly reducing the charging pile energy consumption.

Description

technical field [0001] The invention relates to a DC charging connector for an electric vehicle, in particular to a motor locking device and a DC charging connector for an electric vehicle with the motor locking device. Background technique [0002] In the 2015 national standard for electric vehicle charging methods, for the DC charging interface, the standard clearly stipulates that "an electronic locking device should be installed on the vehicle plug to prevent the vehicle interface from being disconnected under load." However, most of the electronic locking devices currently on the market adopt the electromagnet attraction method: that is, the electromagnet pushes the ejector rod, and the ejector rod resists the button buckle, thereby realizing the locking function. Generally, in order to respond quickly and obtain greater locking force, the power of the general electromagnet is relatively large, about 23-24W. In actual use, the high-power electromagnet needs to be power...
