Embodiment
As Fig. 1, the utility model level electronic has a housing 21, its main parts size such as: unlock plectrum switch 5, locking plectrum switch 10, motor 1, screw mandrel 4, screw mandrel supporting base 29, lock pin 8, shift fork 14 and touching part 9 and be placed in this housing 21.Screw mandrel supporting base 29 and motor 1 are arranged on the basic position of center line of the length direction in housing 21, unblock plectrum switch 5 and locking plectrum switch 10 are placed in the side of screw mandrel supporting base 29, and be substantially on a linear position, touching part 9 is arranged on screw mandrel supporting base 29, and can touch one by one with above-mentioned two switches 5,10, produce the signal of telecommunication by touching and be transferred to by the cable 3 be connected with two switches the controller be placed in outside housing 21, by controller the signal of telecommunication processed and produce corresponding control command.Screw mandrel 4 one end is connected with motor shaft, and one end is bearing on screw mandrel supporting base 29, and lock pin 8 is connected to one end of screw mandrel supporting base 29, and front portion is stretched out outside housing 21, to carry out sealed with corresponding snap close, shift fork 14 is slidably connected at the other end of screw mandrel supporting base 29.
As Fig. 2, screw mandrel supporting base 29 is provided with support holes (not shown) in the basic center of length direction, and the L-shaped bending to side in one end of length direction, the end face of a rectangle is formed at bending end, and a dovetail groove 47 is set on this end face, the center line of dovetail groove passes through the diameter of support holes horizontal direction.Lock pin 8 is connected to the non-bending end of screw mandrel supporting base 29 length direction, and with support holes coaxial line position.
Shift fork 14 is provided with the engaging hole 41 being greater than screw mandrel diameter, and the engaging hole 41 of the present embodiment is mounting hole (also can be arranged to the circular hole that diameter is greater than screw mandrel).The internal thread that comprise about three teeth suitable with screw mandrel is provided with at a place in the horizontal diameter direction of this engaging hole 41.The internal thread of this local can be made an inserts being suppressed to be formed by mould in addition, rabbet in the inner hole surface of engaging hole 41.Two asymmetrical thickness sides of above-mentioned its length direction of shift fork 14 are inclined-plane, and make this side of shift fork length direction become swallowtail shape, shift fork 14 is plugged in the dovetail groove 47 on screw mandrel supporting base 29 1 end face by lozenges, and can slide along dovetail groove 47.Shift fork 14 is also provided with unlock hole 24, and the screw mandrel supporting base 29 of its correspondence position is provided with breach 292.
Screw mandrel 4 is through engaging hole 41, and rotatably support, in above-mentioned support holes, makes the internal thread in engaging hole 41 engage with screw mandrel 4 or not engage by shift fork along the movement of dovetail groove 47 simultaneously.When screw mandrel 4 engages with the internal thread in engaging hole 41, screw mandrel 4 is in the rotation driven by motor 1, the screw mandrel supporting base 29 driven by shift fork 14 is done axial movement, lock pin 8 does axial stretching motion thereupon, relative snap close does sealed or unlocking motion, doing sealed or unlocking motion while, by touching part 9 synchronously to the shake-up unlocking plectrum switch 5 or locking plectrum switch 10, information that is sealed or unlocking motion is transformed into electric signal transmission in controller 23, to control the charging process of charger.
In order to ensure screw mandrel 4 and the internal thread good engagement in engaging hole 41, make shift fork and the screw mandrel position of engagement reliable, the utility model is also provided with Flexible element, in order to flexibly to fit on the external screw thread of screw mandrel by the internal thread on shift fork 14, carries out good engagement reliably.The Flexible element of the present embodiment is elastic spring 12, and one end of this elastic spring 12 is connected on screw mandrel supporting base 29, one end compacting shift fork 14.In the present embodiment, owing to being also provided with a unlock hole 24, more preferred mode on shift fork 14, be that the compacting end of elastic spring 12 is placed on the medial surface of unlock hole 24.
As Fig. 3-5, horizontal electronic lock of the present utility model is also provided with hand-operating unlocking mechanism, can unlock when breaking down or have a power failure.This release mechanism has slide block 15, spring 16 and pull bar 17.Pull bar 17 is axially movably connected in housing 21, and one end is stretched out outside housing 21, and the other end is connected with one end of slide block 15.Spring is placed on pull bar 17, and one end is connected with pull bar 17, conflicts on housing 21 in one end.The other end of slide block 15 takes the shape of the letter U bending, and curved end is provided with inclined-plane 26, forms tapered end, and this tapered end is inserted in the breach 292 on screw mandrel supporting base 29, and facing to unlock hole 24 position.The unlock hole of the present embodiment has the medial surface 241 suitable with the inclined-plane 26 of slide block 15 tapered end.Pull pull bar 17, tapered end will stretch into unlock hole 24, and its ramp 26 will the corresponding medial surface 241 of pushing and pressing unlock hole 24, and overcomes elastic spring 12 elasticity press power shift fork 14 is moved laterally, internal thread disengagement in engaging hole 41 is engaged with screw mandrel, realizes manual unlocking merit.Now elastic spring 12 flexural deformation, can produce resilience force.As removed pulling pull bar 17, under the resilience force effect of spring 16 and elastic spring 12, the tapered end of slide block 15 is deviate from from unlock hole 24, and shift fork 14 moves to the inside, and described internal thread engages again with screw mandrel 4.
In order to pull pull bar 17 better, the present embodiment stretches out the outer one end of housing at pull bar 17 and connects stay cord 20.This stay cord 20 one end is through on pull bar 17, and fixed by aluminium pressure pipe 19, the other end forms draw ring by aluminium pressure pipe 19.
As Fig. 6-9, the utility model makes drive motors damage in order to prevent key rotation to be obstructed, be provided with blocking rotation mechanism.This mechanism primarily of U-shaped reed 30, settle the slot 43 of this U-shaped reed and for the active transmission plane of transmitting rotational torque and passive transmission plane composition.In the present embodiment, two active transmission plane symmetry are arranged on motor shaft 11, this just forms the driving section on motor shaft, and slot 43 is set in the end of one end that screw mandrel 4 is connected with motor, and this end is also provided with the hole slot 44 axially arranged, U-shaped reed 30 is plugged in slot 43, the medial surface 441 of hole slot 44 forms with two relative parallel planes 31 inside U-shaped reed 30 space holding motor shaft upper driving portion, on U-shaped reed two relative parallel planes 31 fit in active transmission plane corresponding on motor shaft 11 respectively, with by the torque transfer of motor to leading screw 4, make it rotate.Therefore on U-shaped reed 30 two relative parallel planes 31 constitute passive transmission plane.Under the improper rotary state that screw mandrel 4 rotates blocking, the torque that motor shaft 11 exports is not enough to be rotated by the elastic force turn-screw 4 of U-shaped reed 30, and motor shaft 11 rotates relative to U-shaped reed, and now active and passive transmission is moved plane and mutually do not fitted.
Fix for the ease of U-shaped reed, prevent it from falling along slot 43, by the rectangular bending 301 to side of the both ends of U-shaped reed 30 opening side, and this right-angle bending is articulated on the periphery corresponding to slot 43 side.
