One end of release push rod 230 is articulated on pedestal 100 by a pivot shaft 231, one end of release push rod 230 offers a chute 232, the other end of release push rod 230 then offers a guide channel 233 of corresponding guiding block 221, and this end is convexly equipped with abuts block 234 with one of the opposing configuration of guide channel 233, pivot shaft 231 to penetrate within chute 232 and can vertically moving along chute 232 in chute 232, guiding block 221 is positioned at guide channel 233 and can guide channel 233 vertically moving along guide channel 233, release push rod 230 is made to vertically move whereby.In guide channel 233, be vertically arranged with a back-moving spring 235 along it, two ends of back-moving spring 235 abut internal face and the guiding block 221 of guide channel 233 one end respectively, and after making release push rod 230 be passed release more whereby, energy travelling backwards is to home position.
Locking actuator lever 300 be a metal curved bar, locking actuator lever 300 stage casing be hubbed on pedestal 100, and locking actuator lever 300 can pivotable between a latched position and an actuated position.Wherein one end of locking actuator lever 300 is provided with an actuator shaft bar 310, and the other end of locking actuator lever 300 then offers an actuation aperture 320.
Cage knob connecting rod 400 is a metal curved bar, and the stage casing of cage knob connecting rod 400 is articulated in pedestal 100, and one end of cage knob connecting rod 400 penetrates interlock locking actuator lever 300 in actuation aperture 320, and the other end of cage knob connecting rod 400 is then connected to the cage knob on car door.
Outer door knob connecting rod 600 is a metal curved bar, and the stage casing of outer door knob connecting rod 600 is hubbed on pedestal 100, and outer door knob connecting rod 600 is provided with back-moving spring, and after making it be passed release again, energy travelling backwards is to home position.
Interior door knob connecting rod 500 is a metal curved bar, and the stage casing of interior door knob connecting rod 500 is hubbed on pedestal 100, and wherein one end of interior door knob connecting rod 500 is connected to door knob in one on car door.
Release actuator lever 700 is a metal curved bar, wherein one end of release actuator lever 700 offers a chute 710, the other end of the other end of the release actuator lever 700 then outer door knob connecting rod 600 of pivot joint, this end of outer door knob connecting rod 600 is connected to the outer door knob on car door, and the stage casing of release actuator lever 700 is protruding with a push arm 720.Actuating axostylus axostyle 310 in locking actuator lever 300 is located in chute 710 and makes release actuator lever 700 and locking actuator lever 300 phase interlock, and release actuator lever 700 can be locked actuator lever 300 and drives and be switched to pushing and pressing release push rod 230 relative to outer door knob connecting rod 600 and can be driven by outer door knob connecting rod 600 and promote release push rod 230 pivotable.
When locking actuator lever 300 and being positioned at latched position, release actuator lever 700 misalignment release push rod 230, when locking actuator lever 300 and being positioned at actuated position, the align initial position that abuts block 234 and release actuator lever 700 of release actuator lever 700 can push against when moving and abut block 234 to promote release push rod 230.
Unlocking link 800 is a plastic curved bar, and the other end of door knob connecting rod 500 in one end pivot joint of unlocking link 800 and a part for this end of interior door knob connecting rod 500 are connected to one end relative with release actuator lever 700 on outer door knob connecting rod 600.Therefore, rotating interior door knob connecting rod 500 can drive unlocking link 800 and the outer door knob connecting rod 600 of promotion to rotate simultaneously; But rotating outer door knob connecting rod 600 can make interior door knob connecting rod 500 be separated with it and be failure to actuate.The other end of unlocking link 800 abuts a part for cage knob connecting rod 400 so as to interlock locking actuator lever 300.
Consult shown in Fig. 3 and Fig. 4, it is closed the door and locking state for car door.Buckle 210 is relative with jam plate 220 to be rotated to the closed position of catching groove 211, and locking actuator lever 300 is switched to latched position.Release actuator lever 700 is locked actuator lever 300 and drives and rotate relative to outer door knob connecting rod 600, makes push arm 720 misalignment abut block 234 whereby.When pulling outer door knob, outer door knob connecting rod 600 is driven to rotate and release actuator lever 700 is passed towards release push rod 230, because push arm 720 misalignment abuts block 234, therefore discharge actuator lever 700 and cannot promote release push rod 230 and make latching device 200 discharge lock hook.
Fig. 5 to Fig. 7 is the release mechanism action schematic diagram of automobile door lock when pulling door knob once under aforesaid state.Consult Fig. 5, interior door knob connecting rod 500 is by interior door knob driven rotary, it drives outer door knob connecting rod 600 to rotate and release actuator lever 700 is passed towards release push rod 230, and because push arm 720 misalignment abuts block 234, therefore push arm 720 does not promote to discharge push rod 230 by abutting the side of block 234.
Consult Fig. 6, interior door knob connecting rod 500 pull simultaneously unlocking link 800 make unlocking link 800 push against cage knob connecting rod 400 rotate so that drive locking actuator lever 300 rotate to actuated position.Therefore, discharge actuator lever 700 be locked actuator lever 300 drive and relative to outer door knob connecting rod 600 pivotable make its push arm 720 lateral margin abut abut block 234.
Consult Fig. 7, locking actuator lever 300 turns to actuated position and drives release actuator lever 700 to continue relative to outer door knob connecting rod 600 pivotable, the lateral margin of its push arm 720 is made to promote to abut block 234 vertically moving along release push rod 230, whereby to make abutting block 234 make a concession space for push arm 720 pivotal action.
Consult Fig. 8, door knob in release, outer door knob connecting rod 600 spinning reduction, drive release actuator lever 700 to leave release push rod 230 simultaneously.When push arm 720 leaves abutting block 234, namely release push rod 230 is return and is resetted and abutting block 234 and push arm 720 are aligned.
Consult Fig. 9 and Figure 10, again pull interior door knob to rotate to make interior door knob connecting rod 500, it promotes outer door knob connecting rod 600 simultaneously and rotates and release actuator lever 700 pushed to discharge push rod 230.Due to previous pull interior door knob after make to abut block 234 and align with push arm 720, therefore this time pulling during inside door to make push arm 720 push against abutting block 234 and release push rod 230 is rotated, and interlock jam plate 220 rotates release buckle 210 spinning reduction and discharges lock hook whereby.
When car door close the door and locking state time, the release mechanism of automobile door lock of the present invention can pull door knob connecting rod 500 once and drive unlocking link 800 and locking actuator lever 300, release actuator lever 700 is unlocked whereby.When again pulling interior door knob connecting rod 500, release actuator lever 700 namely can be driven to promote release push rod 230 and discharge lock hook.Passenger pulls door knob once to open car door, therefore can prevent from opening by mistake car door in driving; If forget during passenger getting off car, unblock pulls interior door knob, though cannot open car door immediately, removes vehicle door lock, therefore pulls door knob once namely can open car door again according to its natural reaction.
The foregoing is only preferred embodiment of the present invention, be not used to limit the scope of the claims of the present invention, other use the equivalence of patent spirit of the present invention to change, and all should all belong to the scope of the claims of the present invention.
