Below with reference to attached drawing, the technical scheme in the utility model embodiment is clearly and completely described, shows
So, the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.It is new based on this practicality
Embodiment in type, ordinary skill are left the every other implementation obtained without creative efforts
Example, shall fall within the protection scope of the present invention.
For convenience of understanding the utility model content, can be applied to below using one kind electric used in numerous occasions
Sub- lock core is described；And in being described below, by daily habits, " the rotating clockwise " of electronic lock cylinder is set as unlocking action,
And " rotating counterclockwise " can not then unlock；It is appreciated that only need to slightly adjust corresponding mechanical structure, electronic lock can also be transformed into
" rotating counterclockwise " of core is as unlocking action, and substantial variation does not occur for practical control mode.This should not be made
For the limitation to the utility model, and it should all belong to the scope of protection of the utility model.
Embodiment one：A kind of electronic lock cylinder with lost motion functionality.
As shown in Figure 1, for a kind of structure diagram of the electronic lock cylinder with lost motion functionality；Fig. 2, Fig. 3 are the electronic lock
The detonation configuration of core with different view；It can be seen that include limiting envelope, electronics core, mechanical core, lock in the electronic lock cylinder
Core circuit board and by hollow coil rack, around the electromagnetic coil on coil rack, containing in coil rack cavity
The electromagnet that magnetic bearing, the irony terminal positioned at skeleton rear end collectively form；Wherein lock core circuit board and electromagnet peace
Loaded in the first cavity in electronics core.
Limiting envelope front end is the tapered end through-hole of circular ring type construction, and tapered end through-hole lower end is the outrigger shaft to extend back, extension
It is useful for playing the fixed screw holes being fixed on electronic lock cylinder in the electronic lock lockhole to match on axis.
Electronic lock cylinder is three-stage cylindrical structure structure, is equipped in the centre bore of the cylindric structure of first segment hollow
Hexagon electronic contact, center electron contact are sleeved in lock core insulation sleeve and are installed in hexagon electronic contact；Electronic lock cylinder
First segment cylindrical structure and hexagon electronic contact be located in tapered end through-hole.
Have on the contact plane of the second segment cylindrical structure of tapered end through hole back-end and electronics core and several reset is installed
The return blind hole of pellet and marble spring has several corresponding resets on the contact plane of electronics core second segment cylindrical structure
Blind hole, the depth for resetting blind hole are less than or equal to the radius for resetting pellet, and resetting pellet can partly fall in reset blind hole；Such as Fig. 4
It is shown, you can to see that resetting pellet falls in reset blind hole.
The first cavity in electronics core can be by the upper plenum to install lock core circuit board and to install electromagnet
Lower cavity collectively forms；Wherein upper plenum is the semicircle axially opened up along it from electronics core third section cylindrical structure rear end
Blind hole, lower cavity are the blind round hole opened up in an axial direction from electronics core third section cylindrical structure rear end.
Lock core circuit board is connected with each other with electromagnetic coil by conducting wire and electronic contact；It is located at electronics containing magnetic bearing
Position except the center of circle of core rear end, it is attracting with irony terminal during original state and keep retracted mode；When electromagnetic coil is powered
Generate the magnetic field with repelling each other containing magnetic bearing, you can destroy containing magnetic bearing and the attracting state of irony terminal, make

Groove is sticked into when firmly salient point or bearing are rotated with electronics core or is blocked tongue or is fallen in shrinkage pool, goes back or block salient point,
So as to mechanical core be driven to rotate synchronously by bearing when making unlocking direction rotation electronics core clockwise or counterclockwise, it is located at
The driving lever or striking gear of mechanical core rear end move therewith, and electronic lock cylinder is opened.
2. there is the electronic lock cylinder of lost motion functionality as described in claim 1, which is characterized in that also include in the electromagnet
For when electromagnetic coil is powered off with attracting chime in of bearing and make bearing keep retract in the irony terminal of electronics core state.
3. there is the electronic lock cylinder of lost motion functionality as described in claim 1, which is characterized in that also include in the electromagnet
Carriage spring, the carriage spring are used to that bearing to be made to switch to stretch out shape in electronics core state from retracting when the solenoid is activated
State or be make when electromagnetic coil powers off bearing from stretch out in electronics core state switch to retract in electronics core state.
4. there is the electronic lock cylinder of lost motion functionality as described in claim 1, which is characterized in that first in the electronics core
Lock core circuit board and electromagnetic coil in cavity are installed, refer to that the first cavity in the electronic lock cylinder is divided into installation lock core electricity
The upper plenum of road plate and the lower cavity of installation electromagnet, the upper plenum and lower cavity are respectively the axial direction perpendicular to electronics core
Opening slot or from electronics core rear end along the opening slot of electronics core axial direction.
5. there is the electronic lock cylinder of lost motion functionality as described in claim 1, which is characterized in that the front end of the machinery core is
The mating circular structure with electronics core rear end, the front end for also referring to the mechanical core include the second of cylindrical structure
Cavity, the back end cylindrical columnar structure in the cylindrical structure of electronics core or multistage cylindrical structure are inserted in second cavity
And it can axially rotate.
6. there is the electronic lock cylinder of lost motion functionality as described in claim 1, which is characterized in that the front end of the machinery core is
The mating circular structure with electronics core rear end, the position except the bottom center of circle of the circular structure is equipped with to be matched with bearing
Groove or tongue or shrinkage pool, also or salient point, also refer to include on one side for inclined-plane, while be the groove faced directly or convex
Slot or shrinkage pool, also or salient point.
7. there is the electronic lock cylinder of lost motion functionality as described in claim 1, which is characterized in that also include positioned at electronic lock cylinder
Front end is used to limit the limiting envelope that electronics core moves axially forward.
8. there is the electronic lock cylinder of lost motion functionality as claimed in claim 7, which is characterized in that the electronic lock cylinder also includes
The resetting spring for being used to carry out electronics core inverse unlocking direction rotation between limiting envelope and electronic lock cylinder；Either institute
Limiting envelope is stated also to include several return blind holes in the plane that limiting envelope is in contact with the electronics core and be installed on
Resetting pellet and having on the marble spring for resetting pellet tail end, the electronics core in return blind hole is returned with what limiting was sealed
The position corresponding reset blind hole of blind hole, reset pellet can be by pushing electricity under the action of marble spring to the effect for resetting blind hole
Sub- core, which is turned round and fallen within against unlocking direction, to be resetted in blind hole.
