The specific embodiment

With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of electronic signal of the present utility model drives the motorcycle lock, comprise lock 1 and the movable latch 2 that interts on lock 1, the meaning that latch 2 activities are interspersed in lock 1 be meant latch 2 relatively lock 1 make displacement movement, latch 2 also cannot rotate relative to lock 1, in order to reach this purpose, latch 2 can adopt the post bar with irregular shape of cross section, and the perforation shape of lock 1 is corresponding with it, perhaps on the latch 2 one or more limited block is set, offer corresponding with it bar-shaped trough on the perforated wall of lock 1, or the like, these structures can make latch 2 not rotate, but the utility model preferably adopts the spacing form of vertical bar part, describe to some extent among this embodiment hereinafter.

In order to make head lock to drive in the mode of electronics, this motorcycle lock also comprises double-screw bolt 3 and drive motors 4, the threaded portion 31 of double-screw bolt 3 is plugged in the inner chamber 21 of latch 2 ends, be provided with the latch 6 that matches with the threaded portion in the inner chamber 21, latch 2 is meshing on threaded portion 31 by latch 6, the drive division 32 of double-screw bolt 3 is connected with the rotating shaft 41 of drive motors 4, and the main body 42 of drive motors 4 is fixed on the lock 1.In some embodiments, in order to strengthen the driving force that motor 4 rotates, can be provided with fixed head 5 between the drive division 32 of double-screw bolt 3 and the rotating shaft 41 of drive motors 4.

During practical application, in a single day drive motors 4 receives the driving signal of sending from motorcycle control centre, the rotating shaft 41 of drive motors 4 is rotated, thereby drive double-screw bolt 3 rotations, because latch 2 is meshing on threaded portion 31 by latch 6, and latch 2 is limited can not rotations, therefore double-screw bolt 3 revolutions moving enclose, latch 6 all can on the threaded portion, slide one the circle, promptly can produce between double-screw bolt 3 and the latch 2 and the two adjacent fillets of screw between equidistant displacement, further according to drive motors 4, connected mode between double-screw bolt 3 and the lock 1 as can be seen, drive motors 4 can not produce displacement by relative lock 1 with double-screw bolt 3, and therefore the action that can produce when drive motors 4 rotates will be that latch 2 moves relative to lock 1, wherein, when latch 2 during to the opposite directions motion of double-screw bolt 3, latch 2 stretches out to lock 1 outside, and head lock is locked, when latch 2 when double-screw bolt 3 directions are moved, latch 2 is retracted in the lock 1, the head lock release.

In the present embodiment, be connected in the following ways between the drive division 32 of double-screw bolt 3 and the rotating shaft 41 of drive motors: the terminal fixed cover of drive division 32 is connected to first gear 7, fixed cover is connected to second gear 8 in the rotating shaft 41 of drive motors, and drive division 32 and rotating shaft 41 are by first gear 7 and 8 meshing connections of second gear.By regulating the diameter ratio of first gear 7 and second gear 8, can regulate the rotary speed and the rotation dynamics of double-screw bolt 3, utilize this structure can select the only driving force of unblanking speed and unblanking.Certainly, as another preferred embodiment, the utility model can also adopt the rotating shaft 41 with drive motors directly fixedly to be plugged in the interior form of drive division 32 of double-screw bolt, as shown in Figure 4, this structure makes double-screw bolt 3 have rotating speed faster, guarantees that head lock has the block action of unblanking rapidly, in addition, employed structure is simpler among the relative first kind of embodiment of this structure, gear wherein can be omitted, thereby reduces cost of manufacture and increase reliability.

As preferred embodiment, described latch 6 is for being located at some vertical bars near inner chamber 21 exit positions, and described straight strap clamp places between the two adjacent fillets of screw of threaded portion, and the two ends of vertical bar are plugged on the outer wall of inner chamber 21.Further preferably, adopt parallel mode to place between the vertical bar.The simple structure of this latch 6 both can satisfy the meshing requirement in latch 2 and threaded portion 31, has good self-locking effect, meshing tension in the time of also can avoiding adopting other latch structures causes latch 2 movable inflexible problems, guarantees that latch 2 can have the fastest reaction speed.

Further preferred, 21 outer wall passes described vertical bar along identical direction from inner chamber, and the adjacent position that lock 1 is positioned at latch 2 is provided with fluting 9, and the vertical bar that passes from the outer wall of inner chamber 21 partly is connected on the sidewall of fluting 9.This structure can solve the meshing problem of latch 2 and double-screw bolt 3 on the one hand, can guarantee also that on the other hand latch 2 problem in relative rotation can not occur, and the spacing form of vertical bar part that this promptly is above to be mentioned can be brought dual excellent results.

With reference to Fig. 3, in the present embodiment, the quantity of this vertical bar is two, vertical bar screw thread distribution according to threaded portion 31 when being provided with is placed, vertical bar is set as the plane from passing of inner chamber 21 outer walls, distance separately between the vertical bar equates substantially with distance between fluting 9 the two side, makes two vertical bars can be connected to respectively on the both sides sidewall of fluting 9.Certainly, in actual product, two vertical bars can adopt single vertical bar to replace, and promptly the two ends of single vertical bar are inserted into respectively in the inner chamber 21, and vertical bar is exposed at the part of latch 2 outward as the stop portion between latch 2 and the double-screw bolt 3.

In order to make the structure of head lock obtain excellent protection, this motorcycle lock also comprises an insulation crust 10, and described insulation crust 10 is connected to form a chamber with lock 1, and described drive motors 4 is positioned in the chamber.This makes most of structure of head lock can both obtain the protection of insulation crust 10, guarantees that it is not fragile.

In order to make head lock have good security reliability, described drive motors 4 is preferably stepper motor.Different with general direct current generator is, stepper motor utilizes pulse signal to drive, rather than the used reversal type of drive of common DC motor, and its type of drive is difficult for cracking, and is safe in utilization.Wherein a kind of signal drive circuit schematic diagram of this stepper motor is with reference to Fig. 5.

Above-mentionedly just preferred embodiments more of the present utility model are illustrated and describe; but structure of the present utility model is not restricted to the described embodiments; as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
