113,114, tongue piece 115, tongue piece nut 116 are grounded.
The locking closure 13 snaps onto pivoted housing 12, forms a pivoted housing inner cavity between locking closure 13 and pivoted housing 12, snaps onto one
The pivoted housing 12 risen is rotatably nested in lock housing 11 together with locking closure 13, and the outer end of pivoted housing 12 is set there are two conductive hole 121；Institute
The cam 19 stated is fixedly attached on the output shaft of motor 18, and the fixation of motor 18 is nested in pivoted housing inner cavity, and two are locked contact 113
Activity is nested in two conductive holes 121 of pivoted housing 12, and the outer end for locking contact 113 is opposite with the keyhole in lock housing 11, lock
The inner end of upper contact 113 is electrically connected with motor 18, is resetted 17 activity of pushing block and is nested in pivoted housing inner cavity and can move back and forth along longitudinal direction,
The outer end face for resetting pushing block 17 is opposite with the keyhole in lock housing 11, resets inner end and 19 pivot bush unit of cam of pushing block 17, multiple
The position setting of spring 14 is resetting between pushing block 17 and pivoted housing internal chamber wall, and transversely activity is nested in locking closure 13 on the top of pin 16
On, the lower end of pin 16 and cam 19 are against spring pin 15 is socketed on pin 16 and the both ends of spring pin 15 are pushed up respectively
It leans against on locking closure 13 and cam 19；112 activity of steel ball is nested in pivoted housing inner cavity and steel ball 112 is located at 12 keyhole of pivoted housing
Side wall on, lock body PCB110 and ground connection 114 are all mounted on pivoted housing inner cavity, and lock body PCB110 and motor 18 lock 113 electricity of contact
Connection, ground connection 114 are collided with pushing block 17 is resetted.The fixinig plate 111 is nested in pivoted housing inner cavity, 111 pivot bush unit of fixinig plate
In the outer end of pin 16；The fixed inner end that pivoted housing 12 is socketed in by tongue piece nut 116 of tongue piece 115.
It should be understood that the ground connection 114 can there are many mode, as long as allow key 2 insert can and lock body
PCB110 constitutes circuit, for example changes wiring board into and is wired in lock housing 11, and lock housing 11 is also with the contact of key 2 can be with
, or reset gradient in 17 structure of pushing block, this is also possible contacting with ground connection 114 when only key 2 inserts,
Not necessarily to contact always.
As shown in figure 8, the cam 19 has cam body 191, cam fixture block 192, cam limit block 193, cam
Inclined-plane 194, cam cylindrical surface 195, cam arc groove 196.The outer end cam with outward extension of the cam body 191
Limited block 193, the outer wall of cam body 191 are equipped with cam arc groove 196, and the side wall of cam body 191 is equipped with to extension
The inner end of the cam fixture block 192 stretched, cam body 191 is cam ramp 194, and inside projection one is convex in the cam ramp 194
Take turns cylindrical surface 195.
As shown in fig. 7, the reset pushing block 17 is l-shaped member, it is equipped on 171 inner sidewall of vertical section of l-shaped member
Circular arc set 172, it is inclined-plane 173 which, which covers end face 172, and circular arc set end face 172 and the cam cylindrical surface 195 of cam 19 are matched
It closes, forms the two states of socket with disengaging.
As shown in figure 9, the key 2 includes key shell 21, key bit 22, guide pin 23, thimble 24, ground spring
25, battery 26, grounding elastic slice 27, electrode elastic slice 28, key PCB29.The key bit 22 is fixed on the front end of key shell 21,
The front end of key bit 22, which is equipped with, can allow the steel bead groove 221 that steel ball 112 is caught in lock body 1, and 23 activity of guide pin is nested in key bit
In 22,24 activity of thimble is set in the pilot hole of key bit 22, and ground spring 25 is socketed on thimble 24 and ground spring 25
Both ends acted against on the flange 241 and key shell 21 of thimble 24 respectively, form the spring force of an outside ejection thimble 24, it is electric
Pond 26 is mounted in key shell 21, and grounding elastic slice 27 and electrode elastic slice 28 are all mounted on 21 internal chamber wall of key shell, grounding elastic slice
27 and electrode elastic slice 28 contacted respectively with two electrodes of battery 26 and pass through conducting wire and be electrically connected with key PCB29, two thimbles 24
It connects.
The key shell 21 is made of key top cover 211, key bottom cover 212 and lid main body 213；The key top cover
211 and key bottom cover 212 be separately fixed at the top and bottom of lid main body 213.
The working principle of the invention:
After key 2 is inserted into lock body 1, key bit 22, which pushes, resets pushing block 17, is completed at the same time the connection of ground terminal, ground connection 114 with
It resets pushing block 17 to remain and collides, the thimble 24 and lock body contact while resetting pushing block 17 and being pulled to, on key 2
113 crash, and while resetting pushing block 17 in place, reset the circular arc set end face 172 on pushing block 17 to the cam ramp on cam 19
194 separation is so that limitation failure, key 2 is powered lock body 1 and signal is transmitted rear driving motor 18,18 band of motor
After moving cam 19 rotates 90 degree, cam limit block 193 is limited by the confined planes 123 on pivoted housing 12 and makes 19 overhead cam of cam circle
Arc slot 196 is to upper pin 16, so that the limit of pin 10 is failed, rotates key 2 at this time and drives pivoted housing 12, pin 16 is because of cam 19
Limit fails and has free displacement amount to axle center, and when pivoted housing 12 rotates, 16 head of pin is opposite with the arc groove of 11 inner wall of lock housing
Sliding makes pin 16 to axe movement, to lose the rotary spacing inside lock, realizes and unlocks；When key 2 is inserted into, steel ball 112
The steel bead groove 221 on key bit 22 is slid into, after key 2 rotates, steel ball 112 is limited extremely in steel bead groove 221, makes key 2 can not
It extracts；Key 2 goes back to initial position, and pin 16 bounces reset by spring pin 15, while the limitation failure of steel ball 112, key 2 pull out
Out, 2 withdrawal process of key reset pushing block 17 be reset spring 14 reset, reset pushing block 17 on 173 structure of inclined-plane cooperate cam
194 structure of cam ramp on 19 resets cam 19, and cam 19 comes into force to the limit of pin 16 after resetting, in lockset completion
Lock；Circular arc set 172 on pushing block 17 is resetted to guarantee to reset 17 inclined-plane of pushing block, 173 center with 19 overhead cam cylindrical surface of cam, 195 fitting
It is overlapped with 19 axle center of cam；19 inner face of cam is overlapped with the vertical section 171 for resetting pushing block 17 guarantees that cam 19 will not be because resetting
The elastic force of spring 14 is tilted with 173 matching relationship of inclined-plane；Cam fixture block 192 and 12 confined planes 123 of pivoted housing cooperate, and prevent motor
18 turn to error and lead to not unlock；Pivoted housing face 122 and 4 periphery of motor cooperate, and prevent when violence twists pivoted housing 12, pin
Son 16 withstands cam 19, and cam 19 is displaced and leads to false lock.
The above is only the preferred embodiment of the present invention, therefore cannot be limited the scope of implementation of the present invention with this, i.e., according to
Equivalent changes and modifications made by scope of the present invention patent and description should still belong to the model that the invention patent covers
In enclosing.
