Among the figure: 1, electromagnet; 2, rubber; 3, locking bar; 4, padlock bar back-moving spring; 5, padlock bar; 6, lock shell; 7, locking bar back-moving spring; 8, axletree; 9, locking bar pushes away handle; 10, locking bar cover; 11, fulcrum; 12, electric motor car switch keyhole; 13, power supply.

The specific embodiment

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.

As Fig. 1, Fig. 2, shown in Figure 3, the side of the utility model in lock shell 6 vertically is equipped with electromagnet 1, the little curved end of horizontal positioned " L " shape padlock bar 5 down is equipped with in electromagnet 1 top, one end in " L " shape padlock bar 5 long-armed outsides is connected with padlock bar back-moving spring 4, " L " shape padlock bar 5 long-armed other end and fulcrums 11 are rotationally connected, in the locking bar cover 10 of the opposite side in the lock shell 6 locking bar 3 that can be in axial sliding is housed, locking bar 3 sides are equipped with locking bar and are pushed away handle 9, one end of locking bar 3 is equipped with locking bar back-moving spring 7, the other end of locking bar 3 is equipped with semicircular rubber 2, semicircular rubber 2 can closely cooperate with the rubber 2 of electric bicycle wheel shaft 8 cylindrical annulars, projection above the locking bar 3 is positioned at the medial surface in " L " shape padlock bar 5 little knees, can closely cooperate with " L " shape padlock bar, electromagnet 1 passes through resistance R, electric motor car keyhole 12 and electric vehicle power sources 13 are linked to be path.

As shown in Figure 3, described electric motor car keyhole 12 be divided into close shelves 12.1, start shelves 12.2, unblank shelves 12.3 third gear.

As Fig. 1, shown in Figure 2, when the projection above the locking bar 3 is positioned at the lateral surface in " L " shape padlock bar 5 little knees, need locking, locking bar pushes away handle 9 and is exposed at trivial shell 6 outsides, by the manpower effect turn right the pushing locking bar push away handle 9, locking bar pushes away handle 9 and can slide in lock shell 6 chutes, padlock bar 5 small end faces clockwise rotated around fulcrum 11 along the inclined-plane of locking bar 3 projections when the pushing locking bar of turning right pushed away handle 9, when the pushing distance of turning right is enough big, when the projection above the locking bar 3 is positioned at the medial surface in " L " shape padlock bar 5 little knees, padlock bar 5 rotates counterclockwise around fulcrum 11 under the effect of padlock bar back-moving spring 4 and fastens locking bar 3, the rubber on these hour locking lever 3 tops closely contacts with axletree 8 outer rubbers 2, has promptly reached blocking.As shown in Figure 3, when unblanking electric motor car is started key and insert electric motor car keyhole 12, key is screwed to the shelves 12.3 of unblanking, solenoid circuit conducting this moment, the pushing locking bar of turning right pushes away handle 9, the projection above the locking bar 3 and the medial surface in " L " shape padlock bar 5 little knees are not contacted, when padlock bar 5 clockwise rotates " L " shape padlock bar 5 under the effect of electromagnetic force small end face is positioned at above locking bar 3 projections, unclamp locking bar and push away handle 9, make locking bar 3 under the effect of locking bar back-moving spring 7, get back to initial position, it is the lateral surface that locking bar 3 top projections are positioned at " L " shape padlock bar 5 little knees, the rubber on these hour locking lever 3 tops and axletree 8 outer rubbers 2 unclamp, and are release.Again the electric motor car key is screwed to and starts shelves 12.2, can normally drive a vehicle.Electromagnet power supply 13 is provided by electric vehicle power sources.This lock can be contained in axletree one side or axletree both sides.

The above-mentioned specific embodiment is used for the utility model of explaining; rather than the utility model limited; in the protection domain of spirit of the present utility model and claim, any modification and change to the utility model is made all fall into protection domain of the present utility model.
