Summary of the invention
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, opening door operation at inner side all-or-nothing piece described in described unlocked position transfers to described lifting arm, states opening door operation do not transfer to described lifting arm in described latched position place; 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, and it rotatably links and is maintained at any in unlocked position and latched position with door; Secondary bar, 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; The first stop part, it is arranged on driving lever place and the rotation along unlocking direction at the secondary bar of the first place, permanent position restriction; Control lever, it comprises for actuate the first actuation component of secondary bar along unlocking direction towards the first permanent position, with respect to driving lever and the rotation of secondary bar, can engage with separated with driving lever, and can along unlocking direction, from the second permanent position, rotate by the opening door operation of inner side all-or-nothing piece; The second stop part, it is arranged on driving lever place and the rotation along locking direction at the second place, permanent position restriction control lever; And second actuation component, it actuates control lever along locking direction towards the second 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, secondary bar 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, secondary bar is set for by the first actuation component and driving lever and interlocked.Double-locking mechanism comprises: twin-lock fixed pole, and 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; And link, it is assembled on control lever and can radially with respect to control lever, moves and be integral along its direction of rotation and control lever along it, can be along the moving radially of control lever, and can engage with separated with driving lever by the rotation of twin-lock fixed pole.When twin-lock fixed pole is positioned at not desired location, driving lever and control lever can be connected to each other so that one is rotated each other by the second stop part and link with respect to the rotation of twin-lock fixed pole simultaneously.When driving lever is positioned at latched position and twin-lock fixed pole and is positioned at desired location, driving lever to the movement of unlocked position is limited by twin-lock fixed pole, and link is separated with driving lever, thereby the motivator that allows control lever to overcome the second actuation component moves from the second permanent position.
It should be noted in the discussion above that common double-lock type vehicle door lock also comprises driven outside all-or-nothing piece by being arranged on the operation of the outside door handle on the door that vehicle outside establishes.Therefore, open connecting rod set for can be by outside all-or-nothing piece the opening door operation under the opening door operation of outside door handle and driven, similar to the opening door operation of inner side all-or-nothing piece under the opening door operation of above-mentioned inside door handle.But door lock assembly is set for and made a motor performance (or twice pull operation) is not that opening door operation by outside door handle obtains.
According to above structure, if in double-lock type vehicle door lock when open that connecting rod is positioned at unlocked position, locking mechanism under released state by locking mechanism and double-locking mechanism in double-locking not during set condition (in release time) carry 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.Therefore, carry out the open operation of latching device and can open the door by the opening door operation of inside door handle.Simultaneously, 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, and in company with opening door operation, carries out the open operation of 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 making by inside door handle for and is obtained so-called twice pull operation, 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 by inside door handle (for the first time pull operation and at inside door handle return the pull operation for the second time after once) execution latching device.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 control lever, driving lever, secondary bar 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, control lever, driving lever, secondary bar 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, control lever, driving lever, secondary bar 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.
Meanwhile, under above-mentioned emergency rating, control lever and driving lever are switched to unlocked position and are held.But, owing to overcoming the motivator of the first actuation component, with respect to driving lever, rotate predetermined angular, so secondary bar is not switched to unlocked position.Thus, if secondary bar is simultaneously opened connecting rod along unlocking direction with respect to driving lever rotation by the motivator of the first actuation component and is moved to return position when inside door handle return one time, above-mentioned emergency rating discharges, thereby secondary bar and unlatching connecting rod are switched to unlocked position.
Therefore, because control lever when the pull operation for the second time of inside door handle, driving lever, secondary bar etc. are switched to unlocked position and open connecting rod, move to unlocked position, so the opening door operation of inner side all-or-nothing piece is in company with inside door handle, the opening door operation when the release 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.
Meanwhile, when locking, driving lever and control lever can be connected to each other so that one is rotated each other by the second stop part and link with respect to the rotation of twin-lock fixed pole simultaneously.Therefore,, when control lever is when by inner side all-or-nothing piece, the opening door operation under the opening door operation in inside door handle rotates along unlocking direction, driving lever is along unlocking direction and the rotation of control lever one.Therefore the commitment that, the delay of the opening door operation of inside door handle moves to unlocked position at driving lever from latched position does not occur.As a result, can improve the operation sense when the opening door operation of inside door handle.Meanwhile, even set for while making that the opening door operation by inside door handle obtains a so-called motor performance in when locking when door lock assembly, these advantages have been obtained equally.
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), driving lever is positioned at latched position, twin-lock fixed pole is positioned at desired location, driving lever to the movement of unlocked position is limited by twin-lock fixed pole, and allows the motivator that control lever overcomes the second actuation component to move (along unlocking direction, moving) from the second permanent position by link is separated with driving lever.
Thus, no matter (when double-locking) carries out any opening door operation of inside door handle in the case, control lever all in the follow-up phase of opening door operation the opening door operation by inner side all-or-nothing piece along unlocking direction rotation but stagger with driving lever, thereby the driving lever that is positioned at latched position does not rotate towards unlocked position.Therefore, 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, control lever, driving lever, secondary bar 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 by 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.
In above-mentioned double-lock type vehicle door lock, single parts can be used as for actuating the first actuation component of secondary bar along unlocking direction towards the first permanent position and for actuate the second actuation component of control lever along locking direction towards the second permanent position.Compare and can make door lock assembly simple and cheap in the case, with when the first actuation component is formed by independent parts with the second actuation component.
In above-mentioned double-lock type vehicle door lock, door lock assembly can comprise rotatably link with door and be connected with driving lever in case with the securing rod of driving lever interlocking, and this securing rod can link to interlock with hook knob with the hook knob being arranged on the door of vehicle interior side.In the case, when double-locking, limited by twin-lock fixed pole with the movement to unlocked position of the driving lever of securing rod interlocking and driving lever is maintained at latched position.Therefore,, even hook knob operation, hook knob and securing rod are also motionless, thereby securing rod can not be moved to unlocked position from latched position.Therefore, can improve the safety of door lock assembly.
In above-mentioned double-lock type vehicle door lock, link can comprise the pin portion that coordinates slidably and pass long arc-shaped holes with the long arc-shaped holes of twin-lock fixed pole, and sliding part, this sliding part is assembled on the arm of control lever and can radially with respect to arm, moves and be integral along its direction of rotation and arm along it, and by the rotation of twin-lock fixed pole, link can moving radially and can engage with separated by the taper of pin portion and the arm of driving lever along control lever.
Above-mentioned double-lock type vehicle door lock can further comprise the housing that holds inner side all-or-nothing piece, unlatching connecting rod, locking mechanism and double-locking mechanism, and housing can be risen and be assembled on door with latching device one.

In addition, in the present embodiment, when locking mechanism A3 is in the lock state the Xia Qie double-locking A4 of mechanism as shown in Figure 6 in double-locking not during set condition (in locking time), the joint timing that the joint protuberance 44b of the excrescence 32a4 of the first inner side all-or-nothing piece 32A and control lever 44 is engaged with each other (driving that wherein control lever 44 starts to be driven by inner side all-or-nothing piece 32 starts timing) is made as with the timing (wherein open the driving that connecting rod 33 starts to be driven by inner side all-or-nothing piece 32 and start timing) that urges of wherein opening that connecting rod 33 urged by the taper of the second inner side all-or-nothing piece 32B and compares delay scheduled time (being made as the delay timing that the unlatching connecting rod 33 that is wherein positioned at latched position moves to unlocked position), make to obtain so-called twice pull operation by the opening door operation of inside door handle.
In thering is the present embodiment of said structure, if when open as shown in Figure 3 connecting rod 33 by locking mechanism A3 be positioned at unlocked position, locking mechanism A3 in released state and the A4 of double-locking mechanism in double-locking not during set condition (in release time) carry out the opening door operation of inside door handle, the opening door operation of inner side all-or-nothing piece 32 transfers to the lifting arm 23 of latching device A1 through being positioned at the unlatching connecting rod 33 of unlocked position, and in company with opening door operation, carries out together the open operation of latching device A1.Therefore, can open the door by the opening door operation of inside door handle.
Simultaneously, 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 31 transfers to the lifting arm 23 of latching device A1 through being positioned at the unlatching connecting rod 33 of unlocked position, and in company with opening door operation, carries out together the open operation of latching device A1.Therefore, even can open the door by the opening door operation of outside door handle.
In addition, when open as shown in Figure 6 connecting rod 33 by locking mechanism A3 be positioned at latched position, locking mechanism A3 is in the lock state down and the A4 of double-locking mechanism in double-locking not during set condition (in locking time), opening door operation by inside door handle obtains so-called twice pull operation, and the open operation of twice pull operation by inside door handle (for the first time pull operation and at inside door handle return the pull operation for the second time after once) execution latching device A1.Therefore, can open the door by the opening door operation of inside door handle.
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, control lever 44, driving lever 41, secondary bar 43 etc. are not switched to unlocked position and are positioned at the unlatching connecting rod 33 of latched position that the opening door operation under the opening door operation of inside door handle drives (by upwards urging) by inner side all-or-nothing piece 32 from latched position.In addition,, in the follow-up phase of pull operation for the first time, control lever 44, driving lever 41, secondary bar 43 etc. are switched to unlocked position and open connecting rod 33 and continue by the opening door operation of inner side all-or-nothing piece 32 driven (by upwards urging) from latched position.
Thus, in early and middle portion stage of pull operation for the first time, lifting arm 23 and latching device A1 that the movement of opening connecting rod 33 does not transfer to latching device A1 maintain closed condition (snap close state), thereby can not open the door.In addition, control lever 44, driving lever 41, secondary bar 43 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 33 and are switched to unlocked position from latched position.But, in the case, open driven (by the upwards urging) preset distance of connecting rod 33 and in so-called emergency rating (wherein opening the side of the 33c of the portion that urges of connecting rod 33 and the state that the sidepiece of lifting arm 23 engages).Therefore, because driving force (rotation) does not transfer to the lifting arm 23 of latching device A1 from opening connecting rod 33, thus not carrying out the open operation of latching device A1, thus can not open the door.
Meanwhile, under above-mentioned emergency rating, control lever 44 and driving lever 41 are switched to unlocked position and are kept by spring S4.But the motivator that overcomes torque spring 45 due to secondary bar 43 is rotated predetermined angulars with respect to driving lever 41, so secondary bar 43 is not switched to unlocked position.Thus, if secondary bar 43 is simultaneously opened connecting rod 33 along unlocking direction with respect to driving lever 41 rotations by the motivator of torque spring 45 and is moved to return position when inside door handle return one time, above-mentioned emergency rating discharges, thereby secondary bar 43 and unlatching connecting rod 33 are switched to unlocked position.
Therefore, because being switched to unlocked position and opening connecting rod 33, control lever 44 when the pull operation for the second time of inside door handle, driving lever 41, secondary bar 43 etc. are moved to unlocked position, so the opening door operation of inner side all-or-nothing piece 32 transfers to the lifting arm 23 of latching device A1 in inside door handle etc. under the opening door operation during in above-mentioned release through being positioned at the unlatching connecting rod 33 of unlocked position.Therefore, carry out the open operation of latching device A1, thereby can open the door by the opening door operation for the second time of inside door handle.
Meanwhile, when locking, driving lever 41 and control lever 44 can be connected to each other so that one is rotated each other by the second stop part 41c and link 52 with respect to 51 rotations of twin-lock fixed pole simultaneously.Therefore,, when control lever 44 is when by inner side all-or-nothing piece 32, the opening door operation under the opening door operation in inside door handle rotates along unlocking direction, driving lever 41 is along unlocking direction and control lever 44 one rotations.Therefore the commitment that, the delay of the opening door operation of inside door handle moves to unlocked position at driving lever 41 from latched position does not occur.As a result, can improve the operation sense when the opening door operation of inside door handle.
