Locking device for charging interface

Abstract

The invention discloses a locking device for a charging interface, which can fundamentally prevent the charging interface from being plugged and unplugged by mistake. The locking device comprises a locking pin and a shell, wherein, two sides of a bottom plate of the shell extend outwards, and a fixed hole is respectively arranged on each of the extension parts at two sides of the bottom plate; the bottom plate is equipped with a locking pin through hole which is communicated with an inner cavity of the shell and is matched with the locking pin; the locking pin is movably inserted into the locking pin through hole; a vertically inclined pushing block protruding outwards is arranged at an inner end of the locking pin; a return spring is sheathed on the locking pin and is constrained betweenthe bottom plate and the vertically inclined pushing block; an electromagnet is arranged in the shell, and a horizontally inclined pushing block is arranged at the top of an iron core of the electromagnet and is matched with the vertically inclined pushing; and pushing oblique planes matched with each other are respectively arranged on adjacent end faces of the vertically inclined pushing block and the horizontally inclined pushing block, the lower edge of the pushing oblique plane of the vertically inclined pushing block protrudes, and the upper edge of the pushing oblique plane of the horizontally inclined pushing block protrudes. The locking device has the advantages of fundamentally eliminating potential safety hazards and being very convenient to use.

Description

technical field [0001] The present invention relates to a charging interface, in particular to a locking device for the charging interface. Background technique [0002] At present, the locking devices used for the charging interface are usually manual, which can only prevent negligent misoperation, but cannot prevent intentional misoperation, so that it cannot fundamentally prevent the wrong plugging and unplugging of the charging interface, and eliminate potential safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a locking device for a charging interface that can fundamentally prevent the charging interface from being plugged and pulled out by mistake. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a locking device for a charging interface, including: a lock pin and a housing, the two sides of the bottom plate of the h...
