Description
This invention is an automobile door lock.
After driver starts door lock, leave vehicle, and stay in vehicle by its key, be provided with a function avoiding key to close in car driver or passenger side, this function is located on the instrument board of vehicle front usually.
Traditionally, this function is not quite similar in Europe and Asia.
In general, in Europe, lock does not have electric-mechanic locking and unlocking function, therefore can only electronicly lock.This lock is commonly referred to as " self-locking " formula.
This kind of lock has the manual overvide that one is called as " more control " usually, and this device when an inner bat-handle switch is braked, can pin car door.When car door is closed from outside, this kind of lock can not by manual locking therefore car door maintenance released state, and key can not be locked in car.
Some this type of lock also has emergency lock function sometimes, and this function is braked by the mechanical interface of key, only can use when car door is opening, the safety of vehicle during to guarantee fault.Therefore this function can lock car door in power free situation.This kind of car door, locks in the on state, because be all in the lock state before and after the entrance door of pass.But now car key is arranged in car owner's hand, therefore can not be locked.
And work as closing of the door, locking with key is also the same situation.This is the typical case of driver side car door.Car door is by key lock.
In Europe, the vehicle of some model is provided with the mechanical caging panel that can use in without key situation.In this case, at least one lock in vehicle is equipped with this mechanical function, can prevent this lock from not locked in the on-state.This function is commonly called " forbidding that door capable of being opened is locked ".
In the vehicle being furnished with " self-locking " function, if when vehicle doorn is closed, we can lock vehicle by electronic lock certainly, or by dashboard operation, or by remote manipulator key.In a first scenario, we are in car, and therefore key is not stranded.In the latter case, at us on hand, therefore it is not trapped in car key yet.
If vehicle has one or more door to be in opening, onboard system computer forbids locking the instruction of this or whole car doors usually, leaves vehicle close entrance door and by the risk of key forgetting in car to eliminate.This is control circui function of " forbidding that door capable of being opened is locked ".
An another kind of solution often run into allows locking to move, and once unblock is braked immediately.This is that control circui " cancels door capable of being opened to lock " function.
In the ordinary course of things, in Asia, ideally car door can be locked always or can lock at once once being opened during opening the door in inside.Therefore, lock at some, when closed door, consider and cancel this mechanical function of lock and implemented.This first function is commonly referred to " cancellation ".
When car door opening, the behavior of locking can be braked, and second comfortable function is also suggested, and it allows the car door opened after being closed, still keep locking.Second function is commonly referred to " key-free lock ".It can automatically lock vehicle when not needing insertion or braking car key.It is installed in front door usually, when handle keeps braking outside, is finally closed startup once car door.
This is locked in patent GB2 360 325 and is described.
" cancellation " function is the unlocking motion by central securing rod, by a rotating drive link, closing motion is passed to a part for the lock ratchet of so-called pseudo-ratchet.Accomplish this point, pseudo-ratchet has one and pushes the flange transmitting lever edge and rotate clockwise, and a tenon of this transmission lever moves in a groove of central securing rod, to make this tenon rotate in the counterclockwise direction, turns to released state from lock-out state.
The function of " key-free lock " is the drive link of throwing off by, what realize when the outer all-or-nothing piece being connected to outer handle keeps central securing rod in its latched position.The flange of pseudo-ratchet makes transmission lever arm along rotating clockwise, and therefore the tenon of this bar is free to slide in the groove of central securing rod.
Drive link therefore as a reversing of motion device, and needs an additional shaft and interface element, i.e. flange and tenon, and central locking lever and pseudo-ratchet.It must be formed from steel, to bear and to transmit energy during closed door.
The object of this invention is to provide a kind of car door lock with " cancellation " function, its mechanism is easier, weight is lighter, cheaper, and do not need to transmit lever, therefore part is less.
Accomplish this point, the present invention proposes a kind of car door lock, include the bolt of ratchet, central authorities' securing rod, the outer all-or-nothing piece be connected with outer handle, with interior lock control to be connected in securing rod, and described central securing rod, one is connected to the pseudo-ratchet on ratchet, a lock with " cancellation " function, transmitted by the closing motion of described pseudo-ratchet and unlock the running of central securing rod, its feature is the described embedded element that described device contains described central securing rod, be positioned on described pseudo-pawl track when closed door, described center lock fixed pole is moved by one direction, unlocked position is slid into from latched position.
By means of the present invention, " cancellation " function is realized by the direct cooperation transmission of central securing rod and pseudo-ratchet, and in this sense, all reversion gearshifts, expansion instrument and many contact devices are all removed.
According to the first embodiment, described transmitting device is spring.
Optimal cases is described spring is torsionspring, and described spring element one section of opening one section bends.
Favourable part is, described torsionspring central axis is in the glide direction of described central securing rod.
In order to ensure " key-free lock " function, the flange of described central securing rod and described outer all-or-nothing piece has a shared contact, and the action of this outside all-or-nothing piece makes described flange block described contact and makes described central securing rod be stuck in latched position.
According to the second embodiment, described transmitting device is a tenon be connected with described central securing rod.
Optimal cases is the glide direction of described tenon perpendicular to described central securing rod.
To be described pseudo-ratchet be connected by a public rotation with ratchet optimal cases.
Optimal cases is, the glide direction of described central securing rod is perpendicular to the described common axis of rotation of described ratchet and described pseudo-ratchet.
Optimal cases is, this lock comprises bistable spring, and its stable resting position corresponds to locked, and described bistable spring is advantageously connected to described interior securing rod.
Describe in further detail the present invention hereafter by illustration, these diagrams only represent optimum case study on implementation of the present invention.
Fig. 1 to Fig. 6 is the lock fragmentary, perspective view when " cancellation " MODE of operation set up according to the present invention's first embodiment.
Fig. 7 to Figure 12 is the lock fragmentary, perspective view when " key-free lock " MODE of operation set up according to the present invention's first embodiment.
Figure 13 is the lock fragmentary, perspective view set up according to the present invention's second embodiment.
In the following description, in order to the object simplified, the direction as " upwards " or " downwards " is only considered to the direction in finger figure, and various element may be positioned different directions in lock.
Generally include a bolt 5 according to door lock for vehicle of the present invention and be connected to the outer all-or-nothing piece 4 (this Internal handle is connected to internal lock and controls) of inner handle and a pseudo-ratchet 3 be connected with ratchet 6 with the central securing rod of 6, one, ratchet 1.
Middle all-or-nothing piece 7, by mobile locking of having thrown off outside all-or-nothing piece 4, is connected to central securing rod 1 in a known way.
This lock provides " cancellation " function by pseudo-ratchet 3 to the closed moving transmission device of the unlocking movement of central securing rod 1.
According to the present invention, this device contains the embedded element of central securing rod 1, and be positioned at when closed door on pseudo-ratchet 3 track, center lock fixed pole 1 is moved by one direction, slides into unlocked position from latched position.
Pseudo-ratchet 3 and ratchet 6 to be connected 3A by a public rotation.
The described glide direction of central authorities' securing rod 1 is perpendicular to the common axis of rotation of ratchet 6 and pseudo-ratchet 3.
According to Fig. 1 to 12, first the first embodiment describes " cancellation " function and " key-free lock " function in detail.
In FIG, lock is in and opens and unlocked position.Electronic or mechanical braking makes central securing rod 1 be moved downward to latched position, as shown in Figure 2.
When a vehicle door is closed, in this latched position, the bolt 5 locked rotates and the rotation of pseudo-ratchet 3 making ratchet 6 and be connected with ratchet 6.Therefore ratchet 6 contacts the free bend end 2A of the torsionspring 2 being embedded in central securing rod 1, and it is upwards pushed away.Correspondingly, spring upwardly central securing rod 1 until the maximum rotation of bolt, as shown in Figure 3.In this position, the stroke of center lock fixed pole 1 is 2/3 of its total travel.
More particularly, the central axis of torsionspring 2 is in the glide direction of central securing rod 1.
D/d middle all-or-nothing piece 7 turns back to unlocked position, and namely lock is positioned at released state.
Bolt 5 reaches semi-closed position afterwards, and as shown in Figure 4, ratchet 6 turns back to its resting position.In other words, central authorities' securing rod 1 exceedes 2/3 of its total kilometres, wherein bistable spring 8 only comes across in Fig. 1 and 2, illustrate two corresponding settling position, the unblock that difference is corresponding locks and latched position, bistable spring is located at the end position of its stroke, and the state of lock then remains unlocked state.Bistable spring 8, such as hunting trumpet type bistable spring, optimal cases is connected with inside lock lever 9, and this inside lock lever is bidirectionally coupled to central securing rod 1, thus also guarantees its bistability.
Then, as illustrated in Figures 5 and 6, bolt is rotated further to complete make position, and spring 2 does not have further action, thus does not change the state of lock.
Also being completed by the lock be consistent according to the present invention of " key-free lock " function.
If we consider Fig. 1 again, lock is in be opened and unlocked position.Electric or mechanical braking makes central securing rod 1 be moved down into latched position, as shown in Fig. 2 or 9.Therefore outside all-or-nothing piece 4 is positioned at as shown in Figure 7 on position, is in non-on-position.
Car door is therefore in locking and open mode, and hand is being braked and maintaining, until closing of the door.Outside all-or-nothing piece 4 in rotating clockwise, as shown in Figure 8, and by the tenon contact 1A of its flange 4A towards central securing rod 1 correspondence, also as shown in Figure 9.
When a vehicle door is closed, bolt 5 rotates as shown in Figure 10, and ratchet 6 and pseudo-ratchet 3 are rotated.The latter immediately contacts with monolithic spring 2 and pushes it against top.But central securing rod 1 does not move up, because it is locked jointly by flange 4A and tenon 1A, handlebar keeps on-position.Therefore spring 2 is out of shape and bends.
Therefore maximum rotation produces, and middle all-or-nothing piece 7 remains on latched position, and bolt 5 arrives the semi-closed position shown in Figure 11 afterwards, and after this, ratchet 6 turns back to its resting position.Spring 2 is tightened in the release afterwards of pseudo-ratchet 3 makes it get back to original state, and do not change the state of central securing rod 1, it remains in latched position.
Then bolt 5 continues to rotate until move completely as shown in Figure 12, does not change its lock-out state, tightens all after date retracting springs 2 at another.
This kinematics making its easier compatible Europe class lock simultaneously according to layout of the present invention, and the function of Asian type lock, and its assembly cost is lower.
In other respects, the foundation of " more control " function may be summarized to be a direct inside opening, no matter the synchronism of unlocking motion, and the proposition of " cancellation " function, by increasing a simple little spring, after ensure that breakdown action, the very first time unlocks and locks.
" more control " type lock is compatible with " cancellation " function of adding, and as mentioned above, does not produce kinematics interference.
By adding 4A interface at outside all-or-nothing piece simply, " key-free lock " function can provide " emergency cut-off " function, adds assembly or interface without the need to being added on key interface.
Figure 13 describes the second embodiment of the present invention.
According to this modification, previous embedded spring 2 is replaced by the tenon 2' be connected with central securing rod 1, such as, made thereon by molded, and perpendicular to the glide direction of central securing rod 1.
" cancellation " function is identical with foregoing description, has lacked an assembly, but " key-free lock " function can not realize again.
Relative to " more control " function, we find and above-mentioned identical compatible advantage, but we lose the possibility without specific interface emergency lock.
