Servo driven door lock for vehicle

The invention relates to a lock, in particular a lock for Motor vehicle doors which is electrically actuated and having an emergency opening, according to the features of the preamble of claim 1.

Such a lock is known from European Patent Application 0,589,158 A1 known which like one with a locking bolt or having cooperating rotary latch, which in a locking position of a pawl is locked. A handle is an electric line connected to a motorized actuator which upon actuation of the handle with a movable actuator to the ratchet interacting the Pawl displaced into its open position when in the electric line arranged switch by a corresponding shift command a Receiving device or in related equipment is actively provided. Normally is in active individually or jointly set Microswitches an electromechanical unlocking the pawl provided. An additional mechanical release is only at occurring incidents is used and in these cases the Receiving device, the central of the body electronics or a Switch effectively set. One embodiment provides an additional mechanical actuation mechanism prior to a pivot lever, which in a securing position in which the pivot lever not to the pawl can cooperate. By cooperation of the pivoting lever with the Actuator, the swing lever of the actuator into its active position are pivoted, wherein the actuator from a normal position into a Operating position arrives. For this purpose, the actuator of the to drive corresponding receiver. The pivot lever is on arranged a supporting member which by actuation of the handle of a Resting position can be adjusted linearly in an operating position. located the pivot lever in its active position, thus causing the mechanical Displacement of the supporting part an entrainment of the leg on the locking pawl, thereby releasing these into their unlocking the catch swings. Alternatively, it is provided, the entire actuator to move or twist.

These arrangements have the disadvantage that electrical event of a failure or electronic components (for example, the switch) or the Power supply is to ensure that the load-free actuator in relocated its active position and by example in this active position Self-locking locks, ie, that the movable actuator by means of electrical power in case of failure must be moved into a defined position, by over by actuation of the handle (inside door handle or the outside door handle) one opposite the electrical unlocking a larger adjustment to effect mechanical opening of the doors. If, however, no electrical Energy (z. B. in case of failure of the battery due to cold or after an accident or the battery is in the repair shop or during transportation of Motor vehicle disconnected) available, there is no guarantee that the Actuator assume its defined position or long enough can adhere.

The invention is therefore based on the object, a lock with a additional mechanical transmission device for unlocking provide that in an accident, in particular without electric power , Is effectively operable or failure of the electricity supply.

This object is in the characterizing part of claim 1 dissolved specified characteristics.

First, it should be noted that "electric under the term is unlocking understand "that the unlocking of a electrical pulse is triggered. The pulse may, for example, by the Closing of a switch or by touching a sensitive generates sensor or in any other way (eg., via a remote control) will. This pulse is then, where appropriate, other parameters such. as the child lock switched, in operation commands implemented, wherein the control commands control a positioning device, which is is a hydraulic, pneumatic, electromagnetic or electromotive adjusting device acts. These actuators act directly or stocky (for example by means of a transmission) and optionally with the interposition of a clutch to avoid Overload on the pawl to release the catch or equivalent Configurations.

The concept of the invention now provides that the pawl independently from the position of the actuator in case of failure of the Transmission means is operable. This has the advantage, that in a Accident the lock can be effectively operated, that is, a mechanical attachment is suggested that the failure of is electric unlocking effectively operable. This has the advantage that the This device may occupy any position in an accident, the is not predictable, and the lock can still be operated. In order to then especially without electrical power or failure of the electric power supply, which in an accident of a vehicle may be reliably opened from inside or outside the door.

In development of the invention, the transmission device in the region the pawl a projection having a pivoting lever (Internal lever), which at one arm of the ratchet actuator of the Handle in operative connection can be brought. This is a constructive Embodiment of the transfer means given, which has the advantage that it requires fewer components, occupies little space and for Case that the projection of the lever to the arm of the locking pawl in Active compound is brought, is easy to operate, the pawl of their Locking position in which the catch rests on it, into the open position to twist.

In development of the invention the pawl is in the range a a Projection having Direction linearly movable lever (external lever) arranged of in an arm of the pawl upon actuation of a lock cylinder Can be operatively connected. This is an embodiment available the pawl means of the actuation of a lock cylinder with a Key from the locking twist into the open position. Also so is the castle effectively operable during an incident.

In a further embodiment of the transmission device (in particular a lever or a plant part of the lever) a further actuating device associated directly or with the interposition of Obertragungselementen. This has the advantage that in case of failure of the power supply (for example, an accident) for the coupling of the transfer means for displaying the mechanical redundancy, no additional power supply systems, such. as are emergency batteries or capacitors required, and thus related problems, such as adequate and timely availability of needed energy, can not occur. In the normal case, that is, adequate power supply, the transmission device is of the further actuating device held disengaged to the pawl and in Incident brought in operative connection to the locking pawl, so that these appropriate handling and can be operated in case of failure the door is mechanically open. The further actuating device is designed such that the transfer device, in particular the inner lever, in the active (Ie, in the case where a power supply is available) state except To engagement of the pawl holds and if no sufficient Power is available more, the transmitting device (the Interior lever) directly or with the interposition of transmission elements, for example by turning, tilting, pushing, pulling or Combination thereof, brings to the pawl operatively connected.

In the invention, the further actuating device is a electromotive, electromagnetic (eg electromagnet or hinge type relay) or a pneumatic actuator. This means that given different constructive ways to further to realize adjusting device and in particular the existing space adapt or desired direction of movement and movement form.

In development of the invention, the lever and the lever Pan direction and / or direction of actuation spring loaded. This has the Advantage that the lever or the levers are normally ineffective and only in Incident in the pivoting direction and / or direction of actuation in a range be brought, in which the lever or the lever by operating the Handle or of the locking cylinder in operative connection with the lever arm of the Pawl can be brought.

In a further embodiment, the at least one lever on a Bowden cable with the handle (inside door handle or outside door handle or the Lock cylinder) and independent of each other these operable. This construction has the advantage that the lock of each anywhere (from inside the vehicle, from the outside or by means of a key) the lock can be operated effectively in an accident.

In a further embodiment, the lever has a guide, in this guide a service associated with the Bowden cables slide in a Scenery is plain bearing. Next Made the slider is divided into two parts, with each one Part is connected to a Bowden cable. This provides a structure for Available, which allows a leverage factor of two different locations independently actuated.

In <b>Fig.</b> 6 is a further embodiment is shown in which a further electric motor <b>1:25</b>) Is provided on its output shaft a pinion <b>1:26</b> wearing. The electric motor<b>1:25</b> is at the control device <b>10</b> connected and is actuated by this. Around the pivot point<b>1:14</b> is another pivoting lever <b>1:27</b> with a toothed segment <b>1:28</b> arranged the arm a <b>1:29</b> having. The toothed segment <b>1:28</b> meshes with the pinion <b>1:26</b>, To limit the Movement of the arm <b>1:29</b> are attacks <b>1:30</b> and <b>1:31</b> provided. <b>Fig.</b> 6a shows the position that the inner lever <b>3</b> of the arm <b>1:29</b> disengaged is brought to the lever arm <b>1:22</b>What again a Anti-theft position corresponds. In<b>Fig.</b> 6b has been the electric motor <b>1:25</b> activated such that the inner lever <b>3</b> with the lever arm <b>1:22</b> in Can be operatively connected but is not yet placed. <b>Fig.</b> 6c shows yet even in a different view, the anti-theft position, while in <b>Fig.</b> 6D, that the locking pawl <b>1.3</b> by the electric motor <b>1.7</b> in their Opening position has been moved. The inner lever<b>3</b> is back on the souls connected to the inside door handle or the outside door handle, wherein also here again the backdrop <b>3:13</b> is used. An emergency release by Operation of the internal lever <b>3</b>That by operation of the inside door handle or the outside door handle has been triggered, is in the <b>Fig.</b> 6e and f shown. Here, again each of the inner lever <b>3</b> moved down the nose <b>3.1</b> in contact with the lever arm <b>1:22</b> brought and as the pawl <b>1.3</b> in its open position moves.

In <b>Fig.</b> 7 in addition to the operation already shown and described the pawl <b>1.3</b> through the outer lever <b>2</b> or the inner lever <b>3</b> additional shown that the pawl <b>1.3</b> (Or the toothed segment <b>1.9</b>) In approximately Extension to the lever arm <b>1:22</b> an extension <b>1:32</b> having, on the via pivoted fasteners <b>1:33</b> (For example, a Rod) an internal safety button <b>1:34</b> is movably disposed. In that in<b>Fig.</b> 7a antitheft position shown is this Interior safety button <b>1:34</b> completely immersed in the inner lining of the door, while in the neutral position, he (<b>Fig.</b> 7b), that is, that the door electric motor or on one of the levers can be opened, to approximately Half is extended from the inner lining. In addition to the electromotive opening the door or opening on the outer lever <b>2</b> or the inner lever <b>3</b> , the pawl <b>1.3</b> of the inner locking button <b>1:34</b> are actuated (by pulling) and thus the door can be opened.

<b>Fig.</b> 8 shows, in addition or as an alternative to the previously described and embodiments shown actuators <b>1:35</b> and <b>1:36</b>That alone or may be present together, independently actuated are and preferably in the vicinity of the castle <b>1</b> . are These actuators <b>1:35</b> and <b>1:36</b> serve the emergency opening and are preferably around the pivot point <b>1:14</b> rotatably mounted and act on a bump <b>1:37</b>That on the inner lever <b>3</b> is arranged at a pivoting <b>1:38</b> around the pivot point <b>1:14</b> around (<b>Fig.</b> 8d). The inner lever<b>3</b> is first of the arm <b>1:29</b> the toothed segment <b>1.9</b> on distance kept. This is in the antitheft position (<b>Fig.</b> 8a) of the case. in order to neutral (<b>Fig.</b> 8b to arrive), carried out an electromotive Pivoting of the sector gear <b>1.9</b>, So that the internal lever <b>3</b> in his Operative position is pivoted. This allows the nose<b>3.1</b> with the lever arm <b>1:22</b> the pawl <b>1.3</b> be brought into operative connection (<b>Fig.</b> 8c). Normally, an electromotive rotation of the pawl takes place<b>1.3</b> in its opening position (<b>Fig.</b> 8c), so that for the normal case a movement of the actuators <b>1:35</b> and <b>1:36</b> is not required.

In contrast to is in <b>Fig.</b> 8d a fault, in which the switch <b>1:46</b> in the Locking position of the pawl <b>1.3</b> the region of the recess <b>1:45</b> left or it can be assumed that the switch <b>1:46</b> malfunction is. Since, in this case, the controller<b>10</b> none at all or wrong Signal on the position of the toothed segment <b>1.9</b> receives, is a correct Controlling the electric motor <b>1.7</b> no longer possible so that then by means of the pivoting <b>1:38</b> one of the two actuating elements <b>1:35</b> or <b>1:36</b> on is open in an emergency possible. With pivoting of the actuating element<b>1:36</b> becomes a nose this actuator in operative connection with the bump <b>1:37</b> brought, in turn, the nose <b>3.1</b> of the inner lever <b>3</b> With extension <b>1:22</b> the pawl <b>1.3</b> is brought into operative connection and Thus, the rotary latch <b>1.1</b> releases. The same movement process takes place at a Pivoting of the actuating element <b>1:35</b>, The extension of a <b>1:40</b> which the then with the bump <b>1:37</b> is brought into operative connection (<b>Fig.</b> 8e and f). The actuating elements<b>1:35</b> and <b>1:36</b> preferably only to reach the interior of the vehicle and to operate at a unauthorized operation to prevent from the outside.

The in <b>Fig.</b> 9 and 10 embodiments shown are based also on the structural design, which in the <b>Fig.</b> 1 and partially in the another previous figures is shown.

In <b>Fig.</b> 9a is a decoupled position (an anti-theft position) shown, in this embodiment, a hinged armature relay <b>1:46</b> with a pivot member <b>1:47</b> the castle <b>1</b> added. The inner lever<b>3</b> oR iTS conditioning part <b>3:14</b> is replaced with an arm <b>1:49</b> associated with that of the pivot member <b>1:47</b> for driving the hinge type relay <b>1:46</b> actuated is. In the anti-theft position shown, is coupled out of the internal lever <b>3</b> by the arm <b>1:29</b> the toothed segment <b>1.9</b>, In this position, is the hinge type relay <b>1:46</b> purpose of saving electricity is not driven. It However, it is conceivable also in the in <b>Fig.</b> 9a position shown the Hinged armature relay <b>1:46</b> site for extra redundancy to drive. In<b>Fig.</b> 9b it is shown that the electric motor <b>1.7</b> actuated was and the toothed segment <b>1.9</b> is pivoted so far that the inner lever <b>3</b> operatively connected to the arm <b>1:22</b> the pawl <b>1.3</b> is taken, but the catch <b>1.1</b> of the pawl <b>1.3</b> has not yet been released. In<b>Fig.</b> 9c it is shown that the toothed segment <b>1.9</b> by the electric motor <b>1.7</b> continue has been pivoted so that the locking pawl <b>1.3</b> the catch <b>1.1</b> open has and the door can be opened. When in<b>Fig.</b> 9d position shown, when it comes to a locked and / or child-resistant position is the inner lever <b>3</b> of the driven hinge type relay <b>1:46</b> about the pivot member <b>1:47</b> and the swing arm <b>1:49</b> coupled. Thus, an Opening of the door only over actuation of the electric motor <b>1.7</b>, possibly considering an inlaid child safety, possible. For the Case that the power supply is no longer available, is due the then no longer actuated hinged armature relay <b>1:46</b> the inner lever <b>3</b> pivoted, so that in accordance with the <b>Fig.</b> 9e and 9f by means of actuators <b>1:35</b> and <b>1:36</b> an emergency opening (mechanical opening) is the door possible.

In the <b>Fig.</b> 10a to 10f are the same positions as shown in the <b>Fig.</b> 9a-9f, with the difference that the hinged armature relay <b>1:46</b> outside the direction of movement of the inner lever <b>3</b> is arranged and Movement of the hinged armature relay <b>1:46</b> via a pivot arm <b>1:50</b> on internal lever <b>3</b> Gets transferred. In contrast, the in<b>Fig.</b> 9 shown Embodiment has the advantage that a the same hinged armature relays Size larger Ausschwenkmoment on the inner lever <b>3</b> can be transferred. In the embodiment of <b>Fig.</b> 10 is the pivot arm <b>1:50</b> firmly with the plant part <b>3:14</b> connected, wherein the inner lever <b>3</b> relative to the conditioning part <b>3:14</b> substantially linearly movable. Again, the kinematic reversal possible, so that the hinged armature relay <b>1:46</b> in the energized state the inner lever <b>3</b> so attracting that he disengaged is brought to the arm <b>1:22</b>, And in the currentless state of the spring-loaded inner lever <b>3</b> or the plant part <b>3:14</b> (Where, for example, about the fulcrum of the system part <b>3:14</b> arranged around a torsion spring may be) is pushed away.

Alternatively, or in addition to the more useful in the <b>Fig.</b> 9 and 10 Operation of the internal lever shown <b>3</b> by means of the actuating elements <b>1:35</b> as <b>1:36</b> can the operation of the Bowden cable, the Bowden cables, the lock cylinder, the over linkage or via Interior safety button are provided.

This in <b>Fig.</b> 11 embodiment shown is also based on the structural design, which in the <b>Fig.</b> 1 is shown. In<b>Fig.</b> 11a is a decoupled position (an antitheft position) shown in which the internal lever <b>3</b> out of engagement with the lever arm <b>1:22</b> stands. Thus, the pawl <b>1.3</b> either by a movement of the inner lever <b>3</b> nor by an electromotive motion carried. The castle<b>1</b> also has a pneumatic actuator <b>4</b> on which a housing <b>4.1</b> is, in which a volume <b>4.2</b> with a membrane <b>4.3</b> relative to the surrounding Atmosphere is sealed. At the membrane<b>4.3</b> is a stamp <b>4.4</b> disposed of through a system part <b>3:14</b> of the inner lever <b>3</b> this at a distance to the lever arm <b>1:22</b> holds. Furthermore, the pneumatic actuator<b>4</b> a pressure port <b>4.5</b> , which with a pressure connection <b>4.6</b> provided (<b>Fig.</b> 11b), which extends into a region in which the explosion pressure of the air bag or the belt tensioner is effectively detected.

In <b>Fig.</b> 11b is the opening position of the lock <b>1</b> shown that in itself Normally, on the electromotive movement of the electric motor <b>1.7</b> can cause.

In <b>Fig.</b> 11c is for the castle <b>1</b> the fault is shown in which by the Explosion pressure of the airbag or the belt tensioner, the volume <b>4.2</b> was compressed, so that the membrane <b>4.3</b> is folded and the stamp <b>4.4</b> has moved such that the projection of the internal lever <b>3</b> in Operatively connected to the lever arm <b>1:22</b> is brought. can for this incident the pawl <b>1:22</b> by pulling the inside door handle (and thus shifting the backdrop <b>3:13</b> through the soul <b>3.6</b>) From its locked position in the Open position be placed so that it is possible to open the door. same for for the case that a Bowden cable <b>3:10</b> is present, also a spring <b>3:11</b> and a soul <b>3:12</b> , wherein the soul <b>3:12</b> with the outside door handle communicates.

Thus, in <b>Fig.</b> 11d show that the door can open when the outside door handle is operated and in <b>Fig.</b> 11e shown that the door can be opened when the Inside door handle is operated.

In describing the operation of the embodiment according to <b>Fig.</b> 11 it was assumed that the movement of the pneumatic actuator <b>4</b> of a pressure (pressure wave of deployed airbags for example) is triggered. This has the advantage that these pneumatic Actuator without electrical power manages. Alternatively, it is For example, in the embodiment according to the <b>Fig.</b> 11 conceivable that pneumatic actuator <b>4</b> z. B. the pressure port <b>4.6</b> a electrically operable valve increased air pressure available to provide, by means of which then - in the reverse arrangement and operation of the membrane <b>4.3</b> - The internal lever <b>3</b> out of engagement with the lever arm <b>1:22</b> of the pawl <b>1.3</b> is brought or maintained. This is in Anti-theft and / or child safety position of the case (analog Application of the pneumatic actuator <b>4</b> according to <b>Fig.</b> 11 at a Embodiment example, according <b>Fig.</b> 9). In case of failure of the power supply (For example in case of empty or the battery is disconnected or after a Crash) closes the valve, so that the spring-loaded inner lever <b>3</b> engaged comes with the lever arm <b>1:22</b> the pawl <b>1.3</b>, So that a mechanical Opening the door with the handle on one of the Bowden cables <b>3.4</b> or <b>3:10</b> is possible.

The <b>Fig.</b> 12 shows a cross section of the castle <b>1</b> along in <b>Fig.</b> 1a dashed line shown.

It should be noted that the described lock general at doors, tailgates, glove compartments, tank flaps and like in vehicles, especially passenger cars are running, leaves. The controller may be coupled with an immobilizer so that the anti-theft position is set in active immobilizer or vice versa. In this state, simultaneously or with a Quotes delayed a theft alarm system can be activated.
