The oriented ratchet release lever 114 of dynamic transiting rod 116 is close and forms the trend of cooperation, and insurance connecting rod 120 is arranged on backboard 118
On one hole, it can rotate about, its one end and transiting rod 116 form possible contact and cooperation.
Reference picture 1, transiting rod 116 can be connected with interior unlocking link 212, and interior unlocking link 212 can promote transition
Bar, realize the inner side unblock of door lock.Insurance connecting rod 120 can be connected with the first worm gear 209, and first worm gear 209 can band
Dynamic insurance connecting rod 120, which is realized to insure, conciliates insurance function, and control door outside opens drive connection.
Reference picture 2 and Fig. 3, the actuator internal mechanism 200 also include the first motor 206, the first worm screw 205 and the 3rd
Torsion spring 210, reference picture 1, the 3rd torsion spring 210 are set on the 6th cylinder, and one end of the 3rd torsion spring 210 and the first worm gear
209 coordinate, and the other end and the inwall of actuator housing 201 or the inwall of actuator lid 202 coordinate, and the 3rd torsion spring 210 can limit the
The rotational angle of one worm gear 209.
The first worm screw of output axis connection 205 of first motor 206, the first worm screw 205 are meshed with the first worm gear 209.
When performing electronic solution safe operation, Fig. 8 is seen, the first motor 206 drives the first worm screw 205 to rotate, the first worm screw
205 the first worm gears 209 of drive rotate counterclockwise along diagram, and the first worm gear 209 drives insurance connecting rod 120 along diagram dextrorotation
Turn, the rotate counterclockwise under the twisting force of the 5th torsion spring 117 of transiting rod 116, and the formation of ratchet release lever 114 in the process
Coordinate, and coordinate with the interior also formation for driving release lever 207, when forming state shown in Fig. 7, door lock enters solution safety position.
In this case, if interior unlocking link 212 stirs transiting rod 116, the latter rotates with pawl release lever 114 and ratchet 106,
Door lock unlocks.If pulling external-open connecting rod 112 it is turned clockwise, the latter promotes unlatching connecting rod 113 to overcome external-open spring 111
Torsion rotate counterclockwise, and drive unlatching connecting rod 113 to move to the left.The latter is revolved with pawl release lever 114 and ratchet 106
Turn, door lock unblock.
When perform it is electronic insure operation when, see Fig. 7, the first motor 206 drives the first worm screw 205 to rotate backward, first
Worm screw 205 drives the first worm gear 209 to be rotated clockwise along diagram, and the first worm gear 209 drives insurance connecting rod 120 along the diagram inverse time
Pin rotates, and the latter drives transiting rod 116 to rotate clockwise, and disengages the cooperation of unlatching connecting rod 113 and ratchet release lever 114,
And also disengaged with the interior cooperation for driving release lever 207, when forming state shown in Fig. 8, door lock enters state of insuring.In this feelings
Under condition, interior unlocking link 212 can not stir transiting rod 116, and door lock can not unlock.If pulling external-open connecting rod 112, make its up time
Pin rotates, and the latter drives unlatching connecting rod 113 to overcome the torsion rotate counterclockwise of external-open spring 111, and drives transiting rod 116 to the left
It is mobile.But because the cooperation for opening connecting rod 113 and ratchet release lever 114 disengages, the latter can not be also driven to rotate unblock door lock.
The actuator internal mechanism 200 also includes insurance microswitch 204b, has on the first worm gear 209 micro- with insurance
The cam surface that dynamic switch 204b coordinates.The on off operating mode whether being depressed by the contact insured on microswitch 204b, it is car
Body provides outer guard signal.
Embodiment described above is merely to illustrate technological thought of the present utility model and feature, and its object is to make ability
