According to the one side of present disclosure, a kind of double-lock type vehicle door lock, comprising: latching device, and its door that is assembled in vehicle goes up and is configured to keep the relative body of door under closed condition; Inner side 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 inner side all-or-nothing piece and the lifting arm of latching device, and can between unlocked position and latched position, switch under the opening door operation of inside door handle, in described unlocked position, the opening door operation of inner side all-or-nothing piece transfers to lifting arm, and in described latched position, opening door operation does not transfer to lifting arm; Locking mechanism, it makes to open connecting rod and switches between unlocked position and latched position; And double-locking mechanism, it can not switch between set condition at double-locking set condition and double-locking, in described double-locking set condition, the operation of locking mechanism is limited, described double-locking not in set condition the operation of locking mechanism be allowed to.Locking mechanism comprises: driving lever, it rotatably links and is maintained at any in unlocked position and latched position with door, and in the situation that be associated and move to unlocked position from latched position with the opening door operation of inner side all-or-nothing piece or the locking releasing operation that is arranged on the hook knob on the door of vehicle interior side; Emergency rod, it is assembled on driving lever and can with respect to driving lever, rotates with scheduled volume, and opens connecting rod and links, and make to open connecting rod and switch between unlocked position and latched position; Stop part, it is arranged on driving lever place and the rotation along unlocking direction at place, permanent position restriction emergency rod; And actuation component, it actuates emergency rod along unlocking direction towards permanent position.When opening connecting rod, by driving lever, from unlocked position, move to latched position and while being switched to latched position from unlocked position, emergency rod operates with driving lever one.When opening connecting rod, by driving lever, from latched position, move to unlocked position and while being switched to unlocked position from latched position, emergency rod is set for by actuation component and driving lever and interlocked.Double-locking mechanism comprises: twin-lock fixed pole, itself and door rotatably link and can between the not desired location of set condition and the desired location corresponding to double-locking set condition, not switch corresponding to double-locking.When emergency rod with when opening connecting rod and being positioned at latched position and twin-lock fixed pole and 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 when opening connecting rod and being positioned at latched position and twin-lock fixed pole and being positioned at desired location, the movement from latched position to unlocked position of emergency rod and all-or-nothing piece is limited, and the movement of driving lever from latched position to unlocked position is allowed to.
It should be noted, when double-locking mechanism is in double-locking set condition lower time (when door lock assembly is in the lock state) not, the inner side all-or-nothing piece that driving lever can move to unlocked position from latched position with the opening door operation by inner side all-or-nothing piece engages.In the case, when door lock assembly is in the lock state, door lock assembly can be set for and make 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, locking mechanism under released state by locking mechanism and double-locking mechanism under double-locking state time (in release time) carries out the opening door operation of inside door handle, the opening door operation of inner side all-or-nothing piece transfers to the lifting arm of latching device through being positioned at the unlatching connecting rod of unlocked position by opening door operation in above-mentioned double-lock type vehicle door lock.Therefore, carry out the open operation of latching device and can open the door by the opening door operation of inside door handle.
Meanwhile, common vehicle door lock assembly is also 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 for not only by following the opening door operation of inner side all-or-nothing piece of opening door operation of inside door handle but also driven by following the opening door operation of outside all-or-nothing piece of opening door operation of outside door handle.Thus, if (when release) carries out the opening door operation of outside door handle in the case, the opening door operation of outside all-or-nothing piece transfers to the lifting arm of latching device through being positioned at the unlatching connecting rod of unlocked position, carries out the open operation of opening door operation and latching device.Therefore, even can open the door by the opening door operation of outside door handle.
In addition, if this door lock assembly is set the opening door operation that so-called twice pull operation set for by inside door handle for and is obtained, when open connecting rod by locking mechanism be positioned at latched position, locking mechanism is in the lock state down and double-locking mechanism in double-locking not during set condition (in locking time), the open operation of twice pull operation (pull operation and the pull operation for the second time after the temporary transient return of inside door handle for the first time) 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 for the first time (pull operation for the first time) of inside door handle, the unlatching connecting rod that driving lever, emergency rod etc. are not switched to unlocked position and are positioned at latched position from latched position is the opening door operation under the opening door operation of inside door handle and driven by inner side all-or-nothing piece.In addition,, in the follow-up phase of pull operation for the first time, driving lever, emergency rod etc. are switched to unlocked position and open connecting rod and continue by the opening door operation of inner side all-or-nothing piece driven from latched position.
Thus, in early and middle portion stage of pull operation for the first time, lifting arm and latching device that the movement of opening connecting rod does not transfer to latching device maintain closed condition (snap close state), thereby can not open the door.In addition, driving lever, emergency rod etc. are switched to unlocked position in the follow-up phase of pull operation for the first time from latched position, make to open connecting rod and are switched to unlocked position from latched position.But, in the case, open the driven preset distance of connecting rod and under 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 is switched to unlocked position and is held.But, because emergency rod overcomes the motivator of actuation component, with respect to driving lever, rotate scheduled volume, so emergency rod is not switched to unlocked position.Thus, if emergency rod is simultaneously opened connecting rod along unlocking direction with respect to driving lever rotation by the motivator of actuation component and is moved to return position when the temporary transient return of inside door handle, above-mentioned emergency rating discharges, thereby emergency rod and unlatching connecting rod are switched to unlocked position.
Therefore, because being switched to unlocked position and opening connecting rod, driving lever when the pull operation for the second time of inside door handle, emergency rod etc. move to unlocked position, so under the opening door operation in inside door handle etc. during in release, the opening door operation of inner side all-or-nothing piece transfers to the lifting arm of latching device through being positioned at the unlatching connecting rod of unlocked position.Therefore, carry out the open operation of latching device, thereby can open the door by the 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 double-locking mechanism during in double-locking set condition (at double-locking time), emergency rod and unlatching connecting rod are positioned at latched position, twin-lock fixed pole is positioned at desired location, emergency rod and unlatching connecting rod to the movement of unlocked position is limited by twin-lock fixed pole, and the motivator that allows driving lever to overcome actuation component moves (along unlocking direction, moving) from permanent position.
Thus, no matter (when double-locking) 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 towards unlocked position, do not rotate.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.
Meanwhile, no matter carry out any opening door operation of outside door handle when above-mentioned locking and double-locking, driving lever, emergency rod etc. are not switched to unlocked position and open connecting rod from latched position and maintain latched position.Thus, if carry out the opening door operation of outside door handle when above-mentioned locking and double-locking, 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 from being positioned at the unlatching connecting rod of latched position, does not transfer to the lifting arm of latching device.Therefore, do not carry out in the case the open operation of latching device, thereby can not open the door by the opening door operation of outside door handle.
