Description

The lock that is used for motor vehicle

Technical field

The present invention relates to be used for this field of lock of motor vehicle.

Background technology

Such lock makes the outlet (vent) of a motor vehicle can remain on its fastening position; This lock also allows to discharge described outlet by activating inside or external opening control.Described inside or the outside control system of opening are connected with described lock also and can be activated by a user.A kind of like this lock in the outlet that is installed in vehicle usually.This lock comprises a door bolt, and the function of this door bolt is to fix a finger that is installed on the described vehicle with respect to described lock, and is perhaps opposite, discharges this finger.The action of release pin is called opens lock, and this action allows to discharge described outlet; On the contrary, the action that finger is remained in the lock calls the pass locking, and this action prevents to discharge described outlet.When described port closing, finger is pushed door bolt to its fastening position, and pallet prevents that described door bolt from returning its open position and this lock is maintained in its closed position locking under the situation that does not have external pressure.

In context, described lock connects that part of outside or the inner all-or-nothing piece of being called of external opening control or inner opening control.Prevent that the operation that this lock is opened owing to the outside all-or-nothing piece of actuating is called " forbidding (disablement) "; " enabling (enablement) " is reverse operating, and it allows to open once more this lock when the operation external opening control.For the door of a motor vehicle, carry out these operations by means of a lock handle hand or a motor machine actuator usually.For vehicle back case or Qianmen, also can utilize a door bolt to carry out and forbid or enable operation.

Prevent to be called " super forbidding (super-disablement) " by activating the lock that described inner opening control opens a forbidding.Particularly, super forbidding utilizes inner opening control to open this car door after preventing to stave the window of described car door." remove super forbidding (Un-super-disablement) " is reverse operating, and this allows to open described lock once more when operating in the inner opening control of operation.For a motor vehicle door, these operations are carried out by a special motor machine actuator usually.For example, 406 board cars of the moneys in 2000 that beautiful (Peugeot) company sells, perhaps the A4 board car of Audi (Audi) company money in 2000 uses this lock.

So-called " children's safety (child-safety) " function is meant no matter whether this lock is forbidden, all prevents to utilize inner opening control that lock is opened; This function prevents that car door from unexpectedly being opened in car, prevent that particularly children from opening.It is applied to the back door of motor vehicle usually.For the back door of a motor vehicle, these operations are carried out by means of a control button or a motor machine actuator usually.Golf (Golf) the board car of the money in 2000 that popular (VW) company sells, perhaps La Guna (Laguna) the II board car of money in 2000 of Reynolds (Renault) company adopts this kind technical scheme.

So-called " surmounting (override) " function is meant the function that allows to open described lock when enabling lock, perhaps allows by activating the function that an inner opening control is enabled this lock when being provided with children's safety device.When having an accident, this function allows to enable described lock and allow to open from the outside car door the passenger at the car rear portion place that is provided with the children's safety device that has activated.

So-called " dual surmounting (double override) " function is meant by the described opening control of dual activation used for two steps enabled and opened the function of described lock.

So-called " manually non-(hands free) " function is meant by activating that described external opening control triggers an identifying so that described lock forbidding and---if desired---open the function of this lock automatically.

Now the mechanical lock of a lot of models and electromechanical lock adopt in these functions one or more.Mechanical lock is meant that its opening device for example spurs the lock that cable activates by a mechanical attachment; Electronic lock is meant the lock of its opening device by the transmission device actuating of electro-motor manipulation.

In order to adopt above-mentioned various functions, must setting can provide the sensor of described lock status indication information.A lock function (lock-function) electronic processing system utilizes described lock status information to control the activation or the inefficacy of this function or the sort of function." lock state (Lock state) " is meant all residing kinestates in formation unit of this lock.Be this purpose, state " is opened ", " closing ", " enabling ", " forbidding ", " super forbidding " differ from one another.For example under " opening " state, the kinestate of the door bolt of described lock different with under " closing " state.Equally, under initiate mode, a joint element allows described door bolt to be handled by described outside all-or-nothing piece, and under " forbidding " state, this identical joint unit is in the kinestate that prevents this operation.

In order to determine a state that lock is all, this lock has several sensors usually.The lock state sensor can be one its switch about the binary message of the kinematics position of a point element of this lock is provided.For example, can referenced patent file EP-A-0 059 658, it has described the mode selector of the lock that is used to have the integrated electric forbidding.

For provide described lock be in open mode still be closed condition be that described car door is the information that is in the state of opening or closing, be provided with one and be called as open door sensor (Open Door Sensor, one first switch ODS).This ODS is usually by put to determine that the door bolt of opening and closing state activates according to the displacement degree.Usually, at door closure state, this ODS does not bear mechanical force.

For forbidding and the excited state of judging described lock, use a disabled switch, this switch is for example activated by a bar that is connected with described lock forbidding control system.

For super forbidding and the super disabled status of releasing of judging described lock, use a super disabled switch, this switch is for example activated by a bar that is connected with the super forbidding of described lock control system.

After described car has been parked a period of time, for the non-manually opened process of initialization, utilize a switch that is used to trigger described power driven system, this switch is connected with described external opening control usually.

Therefore, need four switches to guarantee above-mentioned all functions being activated and inefficacy.Above-mentioned example relates more particularly to a Qianmen that is equipped with non-manual function.This function is not set on the back door usually, but may be provided with the children's safety function.Similarly, in order to diagnose the children's safety state of described lock, will use an inner disabled switch, this switch is for example activated by a forbidding control member that is connected to the inside opening control of this lock.

To increase number of switches in the lock be expensive and kinematic design that make this lock is complicated.In fact, position that must each sensor is set to it and activated when making the control system running of described function activation (or inefficacy) described, for described function provides a state indication.

Therefore, need a kind of lock that reduces mode selector that has, and this lock allows to carry out above-mentioned various functions: forbid, enable, surpass forbidding, remove super forbidding, activation/inefficacy children's safety device, surmount, trigger described power driven system.

The specific embodiment

The present invention proposes a kind of electromechanical lock system of because motor vehicle, and this system comprises at least two locks on two doors that are separately positioned on described car.Each lockset has one first switch, and this switch can switch to one second state from one first state by activating a forbidding bar.After this this switch is called disabled switch.

An electronic control unit of described system can receive the signal of the state of the switch of representing each lock.Therefore this control module can provide the signal of state of the lock of a described motor vehicle of representative from the signal of the state of representing described two switches.Therefore, the only switch according in each lock just can be in the disabled status that identical disabled status is determined described lock by the lock of supposing two doors.

Each lock of described system can also have a door bolt, an all-or-nothing piece and a second switch, and this second switch can switch by activating described door bolt and activating described all-or-nothing piece.After this, this second switch will be called multifunction switch, because it can be activated by two different elements of described lock.

Therefore, described electronic control unit can receive a signal from described multifunction switch, and can provide a signal of represent this to originate to the actuating of the described multifunction switch of lock based on the state of described lock with from the switching signal of a disabled switch of giving lock.

Give in the lock at one, therefore the number of switch has reduced to only two, and an interpretation logic unit switches the switching of determining described multifunction switch according to the state of lock with based on described disabled switch the time and originates.

In the following description, term vertically, the position of level, the lock when left and right, upper and lower in reference to the accompanying drawings uses.This position is schematically and can not be considered as restriction to position in this latching operation process.

Fig. 1 is the schematic diagram according to a lock of the system of one embodiment of the invention, and this lock is in the closed position.Lockset among Fig. 1 has the motor machine disable function.

Lockset among Fig. 1 has 1, an outside all-or-nothing piece 2 and inside all-or-nothing piece 7 that is connected to an inner opening control (not shown) that is connected to an external opening control (not shown) of a door bolt.

This figure shows that door bolt 1 is mounted to around 11 rotations of an axis; Door bolt 1 allows described door to open around axis 11 anticlockwise rotations.This door bolt pulls to its open position in the counterclockwise direction by a spring (not shown); And remain on its fastening position by a pallet.Concrete shape and its motion of door bolt are known, are not described in further detail here.In addition, these parts can be modified and not influence according to the present invention the operation of lock.In a kind of known mode, inner all-or-nothing piece and outside all-or-nothing piece can activate the pallet that door bolt is remained on the fastening position of lock.The relative pallet (not shown) with one of this pallet can and be connected to each other together around the rotation of axis, and both cooperate mutually rising described pallet and release bar, thereby allow the door bolt rotation and door is opened.

Fig. 1 has also shown a forbidding bar 3 that can switch a disabled switch 6.In Fig. 1, disabled switch 6 is by finger 31 Mechanical Driven of forbidding bar 3, and this finger is pushed switching push button 61.Described disabled switch is then issued signal of described electronic control unit, and this signal is corresponding to first binary condition, for example " 1 ".So that finger 31 during from switching push button 61 withdrawals, switch 6 is sent out a signal to electronic control unit then when activating forbidding bar 3, and this signal is corresponding to one second binary condition, for example " 0 ".This switch 6 is called disabled switch, because it is switched by a bar 3 that is connected to described lock forbidding control system.

Described forbidding bar 3 can be activated by for example electro-motor, and this motor is by an electronic control unit controls, and the multiple disabled status of described lock is stored and controlled to this electronic control unit.This forbidding bar 3 also can be forbidden, enable and remove super forbidding bar by an outside by a key-actuated and activate.

Operation and explanation to the status signal that sent by disabled switch 6 will be described hereinafter.

Fig. 1 also shows a cam 4, and it can activate by door bolt 1 with by an all-or-nothing piece.In the embodiment in figure 1, cam 4 can be activated by outside all-or-nothing piece 2.By being elaborated cam 4 by fastening 1 mode of handling with a bolt or latch with reference to figure 2a and 2b; The mode of handling by all-or-nothing piece 2 by the cam 4 that is elaborated with reference to figure 3a and 3b.

Fig. 1 has also shown a so-called multifunction switch 5.This switch can be switched by cam 4.In Fig. 1, multifunction switch is not subjected to mechanism.Therefore, this multifunction switch sends out a signal for an electronic control unit (not shown), and this signal is corresponding to first binary condition, for example " 0 ".When cam 4 mechanically acted on switch 5, for example by the inclined-plane 41 that can push switching push button 51, switch 5 sent out a signal then for described electronic control unit, and this signal is corresponding to one second binary condition, for example " 1 ".This second switch 5 is called multifunction switch, because it can be switched by cam 4, and this cam can be activated by two different elements of described lock.

Operation and explanation to the switching signal of described multifunction switch 5 will be described hereinafter.Particularly, the status signal of disabled switch 6 will be used to release the meaning of bright switching signal from multifunction switch 5, be to have been activated or activated by all-or-nothing piece 2 by door bolt 1 to determine multifunction switch 5.

Fig. 2 a and 2b show how cam 4 is handled to switch described multifunction switch 5 by door bolt 1.Fig. 2 a and 2b are the partial views of Fig. 1.

In Fig. 2 a, door bolt 1 is in the lock fastening position.Cam 4 does not apply effect to the button 51 of multifunction switch 5.Cam 4 has a backstop 42 that activates on the protuberance 12 that inclined-plane 41 and is supported on door bolt 1.The position of the lock that in Fig. 2 a, shows, cam 4 is positioned at the equilbrium position with respect to its rotation 44, and its backstop 42 just is being supported on the protuberance 12 of door bolt 1.Therefore, inclined-plane 41 is positioned at the left side of switching push button 51.

Shown in Fig. 2 b, can activate door bolt 1 and make it to reach a lock open position with a kind of known way.In order to reach its open position, door bolt 1 is rotated counterclockwise around its axis 11.In rotary course, the protuberance 12 of door bolt acts on cam 4 by being supported on the backstop 42.Therefore cam 4 rotates counterclockwise around its axis 44 with door bolt 1.This rotation of cam is dragged on the switching push button 51 of multifunction switch 5 activating inclined-plane 41.

Therefore, door bolt 1 rotates to a lock open position from a lock fastening position and causes multifunction switch 5 to switch.Therefore, can obtain the information of similar " door is opened " from the state of multifunctional lock 5.

Now, Fig. 3 a and 3b show the running that cam 4 switches multifunction switch 5 by outside all-or-nothing piece 2.Fig. 3 a and 3b are the partial views of Fig. 1.

In Fig. 3 a and 3b, door bolt 1 is in the lock fastening position.In Fig. 3 a, the actuating inclined-plane 41 of cam 4 does not act on the button 51 of multifunction switch 5.Cam 4 is hinged around 44 rotations of identical axis with outside all-or-nothing piece 2.Cam 4 has a lug boss 43, and outside all-or-nothing piece 2 have one can be against the finger 21 of cam 4 lug bosses 43.In the position of the lock shown in Fig. 3 a, cam 4 is positioned at the equilbrium position with respect to its rotation 44, and inclined-plane 41 is positioned at the left side of switching push button 51 and the right of the finger 21 that lug boss 43 is positioned at bar 2.

When all-or-nothing piece 2 was activated by an external opening control, all-or-nothing piece 2 was around its axis 44 rotation counterclockwise.In rotary course, the finger 21 of described bar contacts on the backstop 43 of cam 4, rotates with bar 2 with pulling cam 4.Then this cam counterclockwise rotates with bar 2 around its axis 44.This rotation of this cam is dragged on the switching push button 51 of multifunction switch 5 activating inclined-plane 41.

Therefore, the rotation of the bar 2 that is activated by external opening control also causes a switching of multifunction switch 5.Therefore, can obtain the information of " external door request of opening " and so on from the state of multifunction switch 5.

Below how two information that provided by identical multifunction switch 5 are provided in explanation.

Particularly, the handover information that is provided by multifunction switch 5 in a given lock depends on the disabled status and the switching signal that depends on from a while in the described lock of disabled switch 6 of described lock.

The disabled status of described lock is provided by two disabled switches 6,6 ', and these switches can provide the information of the disabled status of relevant this lock, just distinguishes " enabling ", " forbidding " and " super forbidding " state.But a switch can only provide two independent status informations.Therefore, need two disabled switches that above-mentioned three required information are provided.

Therefore, the present invention proposes a kind of lock system.The state of described lock is to all of described vehicle or normally identical concerning two Qianmens of a car at least.Therefore, can adopt two locks that respectively have a symmetry of a disabled switch 6 to define nearly four kinds the different conditions of described lock.

Fig. 4 a to 5c shows according to a kind of like this system of the present invention.What series of drawing 4a to 4c showed is the partial view that is arranged on a lock in the left front door according to the present invention, and series of drawing 5a to 5c demonstration is the partial view that is arranged on a lock in the right front door according to the present invention.As seen, the direction of rotation of door bolt and cam is opposite between on the left side lock and the right lock, and to the not at all influence of operation as the lock of description among Fig. 1 to 3.

Fig. 4 a and 5a show first state of the forbidding of described vehicle, are defined as " enabling " state.This first state is determined according to the signal that sends from two disabled switches 6,6 ' that are separately positioned on left front door (L) and right front door (R) by an electronic control unit (not shown).In a kind of usual way, signal LR=' 01 ' represents the lock initiate mode on the left side and the right.

Fig. 4 b and 5b show second state of the forbidding of described vehicle, are defined as " forbidding " state.This second state is defined as by an electronic control unit: in a kind of usual way, described electronic control unit specification signal LR=' 10 ' represents the lock disabled status on the left side and the right.

Fig. 4 c and 5c show the third state of the forbidding of described vehicle, are defined as " super forbidding " state.This third state is defined as by described electronic control unit: in a kind of usual way, described electronic control unit specification signal LR=' 00 ' represents the super disabled status of lock on the left side and the right.

State such as following table corresponding to the disabled switch of Fig. 4 a to 5c show.

SW 1L	SW 1R	The state of described lock
			0	1	Enable
1	0	Forbidding
			0	0	Super forbidding

SW 1L refers to be arranged on the disabled switch of offside door internal lock;

SW 1R refers to be arranged on the disabled switch of offside door internal lock.

By the above-mentioned three kinds of states according to disabled switch 6,6 ' definition of the present invention are the states that define in a kind of atemporal mode by the state decoding of being released two bright switches by an electronic control unit.Should be noted that strict these states are not to provide the disabled switch 6 of the state of described lock, 6 ' binary condition with a kind of absolute mode in fact, but by described electronic control unit according to the decoding of the state of disabled switch to the state of this lock.

When described electronic control unit is handled the state change of described lock, for example this unit allows when a super disabled status changes to an initiate mode after identification machinery or non-manual electronic are unblanked, or when this unit triggers when vehicle begins to travel when an initiate mode changes to a disabled status, described electronic control unit can also be handled forbidding bar 3,3 ' actuating.

Now the described electronic control unit of explanation is how based on a state of giving lock with based on the source of the actuating of the multifunction switch of determining this lock from a switching signal of the interior disabled switch of this lock.

Refer among the 5c that at Fig. 4 a the door bolt of described lock is in the lock fastening position, and multifunction switch 5,5 ' is not mechanically applied effect.

In the structure shown in Fig. 4 a and the 5a, if multifunction switch 5,5 ' switches respectively, described lock " is activated ", and this is because the door on the left side or the right is opened by this or that all-or-nothing piece respectively.Therefore, door bolt 1 has acted on the cam 4 that has switched multifunction switch 5.

In the structure shown in Fig. 4 c and the 5c, if multifunction switch 5 or 5 ' switches respectively, described lock " is surpassed forbidding ", this is that this is because because super forbidding causes any actuating of inside or external opening control that door is opened because cam 4 is activated to begin one " non-manual procedure " by described outside all-or-nothing piece.

In the structure shown in Fig. 4 b and the 5b, if multifunction switch 5 or 5 ' switches respectively, described lock is " forbidding ", has both possibilities.A kind of may be that multifunction switch 5 is switched by activating door bolt by cam, and then surmounting of causing of the actuating of door by inner opening control opens; Another kind may be that multifunction switch 5 can begin one " non-manual procedure " by cam by activating outside all-or-nothing piece switching and control electronic installation.

Fig. 6 a and 6b show two kinds of explanations how distinguishing from the signal of multifunction switch 5.State shown in Fig. 6 a is corresponding to the state shown in Fig. 4 b, and just, forbidding bar 3 mechanically acts on disabled switch 6 and cam 4 does not mechanically act on multifunction switch 5.

If multifunction switch 5 switches, this is because door bolt 1 or described outside all-or-nothing piece (Fig. 6 does not show) act on cam 4, and the control electronic installation knows that the lock shown in Fig. 6 a and 4b is in " forbidding " state.If door bolt causes the switching of multifunction switch 5, this means that this door bolt is in open mode and lock has become the state corresponding to Fig. 4 a defined " enabling ", just, disabled switch 6 also switches certainly.In fact, when when being in " forbidding " state, door can only be by the inner opening control of actuating " surmounting " open.

Shown in Fig. 6 b, inner all-or-nothing piece 7 can activate forbidding bar 3 by mechanical attachment parts that are connected to the coupling components that makes the forbidding inactivation.Surmount system and generally include mechanical attachment parts, particularly accident occurs and control by motor not necessarily reliably under the situation at vehicle because surmounting system must be effectively always.For this reason, an inner all-or-nothing piece 7 can act on one and surmounts bar 8.Surmount bar 8 and pivot, and have a leg 81, this leg 81 can promote to forbid the finger 31 of bar 3 and make finger 31 rotations to switch disabled switch 6 around a for example axis identical with the axis of cam 4.

When door was opened, described electronic control unit can be controlled the actuating of forbidding bar 3, thereby disabled switch 6 ' is placed a state corresponding to initiate mode, and described lock is symmetrical in and is not surmounted the door of opening.

But disabled switch 6 does not switch if multifunction switch 5 switches, and this means that multifunction switch 5 has been passed through outside all-or-nothing piece but not passed through door bolt by cam 4 to switch.Therefore, if car is at a stop, electronic control unit can be interpreted as asking one " non-manual procedure " to the switching of this multifunction switch; If lock forbidding and car are under steam, this control module can be interpreted as it to attempt to make a forcible entry in the car outside car.Under all these situations, this lock can not changed into open mode by activating described outside all-or-nothing piece---enable till control operation finishes up to described non-manual identification process and an electronics thereafter.

Equally, if consider the structure of the lock as shown in Fig. 5 b, it is symmetrical in the lock of the door of the offside shown in Fig. 4 b, if described multifunction switch 5 ' switches, described electronic control unit will consider that whether described disabled switch 6 ' also surmounts of bar by one and may activate and switch, and the wherein said bar that surmounts promotes to surmount the finger of bar 3 ' to push down the switching push button of switch 6 '.

Following table provides the explanation of giving the actuating source of the multifunction switch 5 in the lock to.

SW1 is meant described lock disabled switch;

SW2 is meant the multifunction switch of described lock;

Activate the actuating source of source: SW2, just door bolt or outside all-or-nothing piece (EOL);

Effect: activate the effect that the SW2 on the described door causes.

The state of described lock	SW1	SW2	Activate the source	Effect
					Enable	-	Switch	Door bolt	Door is opened
Forbidding	Switch	Switch	Door bolt	Door is opened by surmounting
					Forbidding	Do not switch	Switch	Outside all-or-nothing piece EOL	Non-manual procedure request, or attempt to make a forcible entry in the car
Super forbidding	-	Switch	EOL	Ask non-manual procedure

Therefore, described electronic control unit can explain the implication of a switching of this multifunction switch of giving lock 5 for a while switching signal of the disabled switch 6 the lock from the state and of described lock.

Described electronic control unit can have a for example erasable internal memory that removes the read-only storage type, and this internal memory is local or by the data/address bus of described vehicle it is visited that this data/address bus allows the final state of vehicle lock to be stored in the internal memory.In the interpretation process of the binary signal that switch 5 and 6 is sent to described electronic control unit, the information of original state is used as the input data.Losing under the situation of power supply supply, when restarting, described electronic control unit can read the final state of described lock again and control described lock based on reading again specifically.Need relatively be stored under the particular case of the erasable kinematics time of day that removes information in the read-only storage and described lock at described electronic control unit, can use the diagnostic device of standard when maintenance or when repairing this car.

Described electronic control unit can comprise a microcontroller, and described microcontroller is installed in each lock of system according to the present invention, just is installed in each door of described vehicle.Therefore, if described forbidding control system is electronic, each lock or the microcontroller of each can be controlled the motor that activates described forbidding control system, and therefore activate described forbidding bar.Each lock or the microcontroller of each must can be for example by connecting mutual communication with the electrical connection or the light of network with car institute.Interpretation logic unit further in each lock receives switching signal and switching signal that the state of represent disabled switch 6 changes that a state of represent multifunction switch 5 changes, and this interpretation logic unit can be based on the state of described lock with from one of the described disabled switch switching signal signal that provides an actuating of representing described multifunction switch to originate simultaneously.

One single Electronic Control part also it is contemplated that and is used for whole vehicle, for example in passenger carriage.Therefore, this lock electronic control unit can be for example by all motors and the sensor communication of a special-purpose electrical connection with whole vehicle.

Certainly, the present invention is not limited to by example and the embodiment that is described with reference to the drawings; Especially, special this lock can have different structures in the lock at a back door, and wherein, cam 4 can activate rather than be activated by outside all-or-nothing piece 2 by door bolt 1 with by inner all-or-nothing piece 7.Therefore, described external crossbar 2 can directly activate a specific switch, and this switch does not show in the diagram but is equivalent to described lock disabled switch.When inner all-or-nothing piece 7 is in the child lock disabled status in logic, the interpretation logic of this particular switch is represented an external electric opening request, and the interpretation logic that switch 5 is activated by inner all-or-nothing piece 7 in this case represents that request allows outside open system to surmount.A kind of like this lock is particularly suitable for being equipped with the vehicle back door that child safety lock surmounts software.
