Summary of the invention
The purpose of the utility model provides a kind of simple in structure, stops warm swap fully, safe and reliable electric automobile DC charging plug self-locking device.
The purpose of the utility model realizes through following technical scheme.
A kind of electric automobile DC charging plug self-locking device; It is characterized in that: said electric automobile DC charging plug self-locking device comprises be fastened and connected the button buckle of DC charging plug and charging socket and the electromagnet of control button buckle self-locking, and button buckle and electromagnet are installed on the shell of DC charging plug.
On the said electromagnet push rod is installed; On electromagnet, also be connected with the control circuit of control electromagnet action, button buckle electric automobile DC charging plug self-locking device is drawn together a buckling body and a rotating shaft, and buckling body is installed on the shell of DC charging plug through rotating shaft; One end of buckling body is the clasp of DC charging plug and socket of being fastened and connected; The other end is the buckle press-side, and rotating shaft is installed between clasp and the buckle press-side, between rotating shaft and buckle press-side, button spring is installed; Electromagnet is installed in the below of button buckle, and the push rod on the electromagnet is between the shell that can reach buckle press-side and DC charging plug under the driving of electromagnet.
Said electromagnet is installed in the below in zone between rotating shaft and the buckle press-side of button buckle.
The shell of said DC charging plug is provided with the unlocking apparatus of enforced opening electromagnet action.
The shell of said DC charging plug is provided with the open keyhole of enforced opening electromagnet action, and open keyhole faces push rod, and unlocking apparatus is the shank of unblanking, and on open keyhole, is provided with seal plug.
The utility model compared with prior art has the following advantages:
The utility model is through increasing an electromagnet on the DC charging plug; Prevent user's warm swap through the operating state of control electromagnet; In the charging process, the push rod of electromagnet ejects, and the user can't press the button buckle; Be fastened and connected even the button buckle engages DC charging plug and socket with Socket casing, reach the purpose of self-locking.Because the fail safe and the useful life of electromagnet are higher,, have stopped the phenomenon of user's warm swap fully, and improved security of products and reliability greatly through the mode that this machinery combines with electronics.In order to prevent that the electromagnet push rod from can't return (anomaly), the utility model has been reserved an open keyhole, can promote the electromagnet push rod through the thimble of unblanking and reset.
