Summary of the invention
According to the one side of present disclosure, a kind of twin-lock typing door lock device of vehicle comprises: latching device, its door that is assembled in vehicle go up and be configured to keep door relatively a body be under the closed condition; Inboard all-or-nothing piece, it rotatably links with door and is driven under the operation that is arranged on the inside door handle on the door of vehicle interior side; Open connecting rod, it rotatably links with door, be arranged between the lifting arm of inboard all-or-nothing piece and latching device, and can between unlocked position and latched position, switch under the opening door operation of inside door handle, the opening door operation of inboard all-or-nothing piece transfers to lifting arm in described unlocked position, and opening door operation does not transfer to lifting arm in described latched position; Locking mechanism, it switches the unlatching connecting rod between unlocked position and latched position; And twin-lock decides mechanism, and it can decide set condition and twin-lock does not switch between the set condition surely at twin-lock, decides at described twin-lock that the operation of locking mechanism is limited in the set condition, described twin-lock surely not in the set condition operation of locking mechanism be allowed to.Locking mechanism comprises: driving lever, it rotatably links with door and is maintained in unlocked position and the latched position any, and with the opening door operation of inboard all-or-nothing piece or be arranged under the situation that the locking releasing operation of the hook knob on the door of vehicle interior side is associated and move to unlocked position from latched position; Emergency rod, it is assembled on the driving lever and can rotates with respect to driving lever with scheduled volume, and opens connecting rod and links, and make and open connecting rod and switch between unlocked position and latched position; Stop part, it is arranged on the driving lever place and limits the rotation of emergency rod along unlocking direction at the place, permanent position; And actuation component, it actuates emergency rod along unlocking direction towards the permanent position.Move to latched position and when unlocked position switch to latched position, emergency rod with driving lever one operate by driving lever from unlocked position when opening connecting rod.Move to unlocked position and when latched position switch to unlocked position, emergency rod set by actuation component and driving lever interlocking by driving lever from latched position when opening connecting rod.Twin-lock is decided mechanism and comprised: two securing rods, itself and door rotatably link and can be corresponding to the twin-lock not desired locations of set condition and decide corresponding to twin-lock to switch between the desired location of set condition not surely.When emergency rod with open connecting rod and be positioned at latched position and two securing rod when being positioned at not desired location, allow emergency rod and open connecting rod to move to unlocked position and allow driving lever to move to unlocked position from latched position from latched position.When emergency rod with open connecting rod and be positioned at latched position and two securing rod when being positioned at desired location, emergency rod and all-or-nothing piece mobile being limited, and mobile be allowed to of driving lever from latched position to unlocked position from latched position to unlocked position.
It should be noted that decide mechanism when twin-lock and be in twin-lock set condition following time (when door lock assembly is in the lock state) not surely, driving lever can engage from the inboard all-or-nothing piece that latched position moves to unlocked position with the opening door operation by inboard all-or-nothing piece.In the case, when door lock assembly was in the lock state, door lock assembly can be set for and make and to carry out a so-called motor performance or twice pull operation by the opening door operation of inside door handle.
If when opening that connecting rod is positioned at unlocked position by locking mechanism, locking mechanism is under the released state and twin-lock is decided mechanism and is in the opening door operation that twin-lock is decided state following time (in release time) execution inside door handle, then the opening door operation of inboard all-or-nothing piece transfers to the lifting arm of latching device by the unlatching connecting rod of opening door operation through being positioned at unlocked position in above-mentioned twin-lock typing door lock device of vehicle.Therefore, carry out the open operation of latching device and can opening the door by the opening door operation of inside door handle.
Simultaneously, the common vehicle door lock assembly also is included in driven outside all-or-nothing piece under the operation of outside door handle on the door that is arranged on vehicle outside.Opening connecting rod sets not only the opening door operation of the outside all-or-nothing piece of the opening door operation of inboard all-or-nothing piece of the opening door operation by following inside door handle but also the opening door operation by following outside door handle for and is driven.Thus, if (when release) carries out the opening door operation of outside door handle in the case, then the unlatching connecting rod of opening door operation through being positioned at unlocked position of outside all-or-nothing piece transfers to the lifting arm of latching device, carries out the open operation of opening door operation and latching device.Even can open the door therefore, by the opening door operation of outside door handle.
In addition, if this door lock assembly is set the opening door operation that makes so-called twice pull operation set for by inside door handle for and is obtained, then when open connecting rod by locking mechanism be positioned at latched position, locking mechanism is in the lock state down and twin-lock decide mechanism and is in twin-lock surely not during set condition (in locking time), the open operation of twice pull operation (first time pull operation and the pull operation second time after the temporary transient return of inside door handle) the execution latching device by inside door handle.Therefore, can open the door.
(when locking) in the case, in the early and middle portion stage of the opening door operation first time of inside door handle (for the first time pull operation), driving lever, emergency rod etc. are not driven by the opening door operation of inboard all-or-nothing piece under the opening door operation of inside door handle from the unlatching connecting rod that latched position switches to unlocked position and is positioned at latched position.In addition, in the follow-up phase of the pull operation first time, driving lever, emergency rod etc. switch to unlocked position and open connecting rod and continue to be driven by the opening door operation of inboard all-or-nothing piece from latched position.
Thus, in the early and middle portion stage of the pull operation first time, the move lifting arm and the latching device that do not transfer to latching device of opening connecting rod maintain closed condition (snap close state), thereby can not open the door.In addition, driving lever, emergency rod etc. switch to unlocked position in the follow-up phase of the pull operation first time from latched position, make that opening connecting rod switches to unlocked position from latched position.But in the case, the unlatching connecting rod is driven preset distance and is under the so-called emergency rating.Therefore, because driving force does not transfer to the lifting arm of latching device from opening connecting rod, thus not carrying out the open operation of latching device, thus can not open the door.
Under above-mentioned emergency rating, driving lever switches to unlocked position and is held.But, owing to emergency rod overcomes the motivator of actuation component and rotates scheduled volume with respect to driving lever, so emergency rod does not switch to unlocked position.Thus, if emergency rod is simultaneously opened connecting rod along unlocking direction with respect to the driving lever rotation by the motivator of actuation component and is moved to the return position when the temporary transient return of inside door handle, then above-mentioned emergency rating discharges, thereby emergency rod and unlatching connecting rod switch to unlocked position.
Therefore, since the second time of inside door handle during pull operation driving lever, emergency rod etc. switch to unlocked position and open connecting rod and move to unlocked position, so under the opening door operation during in release such as inside door handle, the unlatching connecting rod of the opening door operation of inboard all-or-nothing piece through being positioned at unlocked position transfers to the lifting arm of latching device.Therefore, carry out the open operation of latching device, thereby can open the door by second opening door operation of inside door handle.
In addition, when open connecting rod by locking mechanism be positioned at latched position, locking mechanism is in the lock state down and twin-lock when deciding mechanism and being in twin-lock and deciding set condition (in the twin-lock timing), emergency rod and unlatching connecting rod are positioned at latched position, two securing rods are positioned at desired location, emergency rod and unlatching connecting rod are to the two securing rods restrictions of the mobile quilt of unlocked position, and the motivator that allows driving lever to overcome actuation component moves (moving along unlocking direction) from the permanent position.
Thus, no matter (at twin-lock regularly) carries out any opening door operation of inside door handle in the case, driving lever is all at stagger emergency rod and open connecting rod of the follow-up phase of opening door operation, thereby is positioned at the emergency rod of latched position and opens connecting rod and do not rotate towards unlocked position.Therefore, the emergency rod of locking mechanism maintains lock-out state in the case, thereby can not open the door by the opening door operation of inside door handle.
Simultaneously, no matter regularly carry out any opening door operation of outside door handle at above-mentioned locking and twin-lock, driving lever, emergency rod etc. do not switch to unlocked position and open connecting rod from latched position and maintain latched position.Thus, if regularly carry out the opening door operation of outside door handle at above-mentioned locking and twin-lock, then the opening door operation of outside all-or-nothing piece transfers to the unlatching connecting rod that is positioned at latched position in company with opening door operation, but does not transfer to the lifting arm of latching device from the unlatching connecting rod that is positioned at latched position.Therefore, do not carry out the open operation of latching device in the case, thereby can not open the door by the opening door operation of outside door handle.
