Compared with the prior art, thereby it realizes the unblock through the physical mode to the round pin axle operation, its simple structure, and the effect is obvious, and can not influence the circuit of rifle that charges at the unblock in-process, can not cause destruction to the rifle that charges.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic locking diagram of the electronic lock of the present invention;
fig. 3 is the unlocking schematic diagram of the electronic lock of the present invention.
Wherein, the gun comprises a gun head 1, a gun body shell 2, a mechanical lock catch 3, an electronic lock 4, a pin shaft 4-1, a microswitch 5, an unlocking bracket 6 and an unlocking pin 7.
Detailed Description
The invention is described in further detail below with reference to the drawings in the specification:
the utility model relates to an electric automobile's battery charging outfit, specific theory is a rifle that charges that can separate battery charging outfit and vehicle after having the outage. With traditional rifle that charges the same, it has also included rifle head 1, body of a gun shell 2, sets up locking device and locking at body of a gun shell 2 and rifle head 1, the difference is, the utility model discloses set up manual emergent unlocking device in locking device department and be used for carrying out the unblock to locking device.
Specifically, the manual emergency unlocking device comprises an unlocking support 6 and an unlocking pin 7, wherein the unlocking support 7 is arranged on the gun body shell 2, the unlocking support 6 is of a hollow structure, one end of the unlocking support 6 is arranged on the surface of the gun body shell 2, and the other end of the unlocking support extends inwards and is in contact with the locking device;
furthermore, the unlocking pin 7 is hung on the gun body shell 2, and the shape of the unlocking pin 7 is consistent with that of the unlocking support 6.
The utility model discloses in, locking device include electronic lock 4, mechanical hasp 3 mechanical hasp axle 3 is connected on rifle head 1, and the one end of mechanical hasp 3 sets up down the splenium, and the other end sets up joint portion, joint portion and 2 joints of body of a gun shell set up the extension at joint portion downside, extension downwardly extending and 4 contacts of electronic lock.
