The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described:

By Fig. 1, Fig. 2 (a) Fig. 2 (b) Fig. 2 (c) the locations of structures function of the part parts of anti-theft device is described:

Attaching plug 8 among Fig. 1 is leads of drawing from battery of electric vehicle; it directly inserts in the supply hub 7; give whole anti-theft device power supply; by anti-theft device self is protected simultaneously; lead 12 is in the middle of the lock rope 11; two respectively with tapered end 9 on contact 13 be connected with contactor 3 among Fig. 5, the keyhole 18 of common lock 21 and the switching button 16 of changeover switch 5 are that the objects of cryptopart 17 special protections are in the same protective trough, are protected by locking closure 10.

Be provided with hard contact 14 in the lockhole 19, it joins by lead and spring multichannel contact-making switch 4, the contact 15 of spring multichannel contact-making switch 4 also is located in the lockhole 19, when tapered end 9 inserts in the lockhole 19, lockhole contact 14 can contact with tapered end contact 13, spring contact 15 can since tapered end 9 be extruded lockhole 19, the inner contact of spring multichannel contact-making switch 4 is contacted, after tapered end 9 is withdrawed from lockhole 19, spring contact 15 can rebound in the lockhole 19 automatically, and the inner contact of spring multichannel contact-making switch 4 is separated voluntarily.

By the safe handling aspect circuit diagram is described in conjunction with the accompanying drawings;

Attaching plug 8 among Fig. 1 inserts in the supply hubs 7, and tapered end 9 inserts in the lockholes 19, the switching button 16 of changeover switch 5 is pressed down (that is: the C among Fig. 5 ₁With C ₂, D ₃With D ₄, B ₁With B ₅, E ₃With E ₄These several groups of contacts link to each other) locking closure 10 that closes then put down rain-proof cover 20 at this moment whole system be in normal operating condition, (that is: the magnet contact A of contactor among Fig. 52 and contactor 3 ₁, a ₃, b ₃, S receive power supply for the acting running status, the contact b of contactor 2 and contactor 3 under magnet acting state ₁With E ₁, B ₁With D ₁, b ₄With S ₅, S ₃With S ₂, these several groups is separated position.) spring contact 15 and the tapered end 9 of spring multichannel contact-making switch 4 collide, and makes spring contact 15 withdraw from lockhole 19, makes it inner contact (that is: the A among Fig. 5 that contacts ₃With A ₂, B ₂With B ₃, C ₃With C ₄These several groups contact) tapered end contact 13 contacts with lockhole contact 14, and the battery of electric vehicle electric current among Fig. 5 is kept the whole system operation simultaneously by spring multichannel contact-making switch 4, the 1 automatic charging of changeover switch 5 accumulators.

If open anti-theft device, a promptly glad rain-proof cover 20 is opened locking closure 10 by cryptopart 17 and key is inserted again and open lock in the keyhole 18 and withdraw from tapered end 19 (that is: the A among Fig. 5 ₃With A ₂, B ₂With B ₃, C ₃With C ₄The contact is a separated position) whole system is in the state of quitting work.

Anti-theft device continues operation if take battery of electric vehicle away, only needs the button 16 of changeover switch 5 is decontroled (that is: the D among Fig. 5 ₂With C ₅, b ₂With E ₂Two groups of contacts link to each other, and all the other contacts separate, and whole system can be kept operation, that is: the magnet contact A of contactor 2 by battery 1 power supply ₁With a ₃Dead electricity in the acting operation, does not make contact b ₁With E ₁, B ₁With D ₁Link to each other, the electric current of battery 1 arrives contactor 3 by contactor 2 changeover switches 5, makes magnet contact b ₃, S obtains electric current and continues operation)

Circuit diagram is being described by antitheft analysis below in conjunction with accompanying drawing:

Suppose under normal operation anti-theft state lock rope 11 to be cut off, that is: lead 12 disconnects, (that is: the S among Fig. 5 to the contact of tapered end 9 separately, i.e. the magnet contact S dead electricity of contactor 3, magnet doing work, does not make b ₄With S ₁, S ₃With S ₂The contact links to each other, and makes electric current directly arrive alarm sound 6) start immediately and report to the police.

Suppose under normal operation anti-theft state, to take battery of electric vehicle away, pull up attaching plug 8 (that is: the magnet contact A of the contactor among Fig. 52 and contactor 3 ₁, a ₃, b ₃, the S dead electricity is not in operation.That is: b ₁With E ₁, B ₁With D ₁The contact links to each other, and the electric current that makes battery 1 is by contactor 2 changeover switches 5 arrival alarm sounds 6) opened warning immediately.

According to above technical scheme those skilled in the art, can be according to the needs of actual conditions, the anti-theft device of design respective shapes, size.(the corresponding electronic original part that do not draw among the figure can add the respective electronic original paper according to actual needs, prevents the electric current adverse current).
