Description

An actuating device and method for actuating a locking device of a vehicle

description

The invention relates to an actuating device for actuating a locking device of a vehicle according to the preamble of claim 1 and to a method for actuating a locking device of a vehicle. Such an actuating device realized, for example, by an outside door handle of a vehicle door, has an adjustable handle part and an actuating element coupled to the handle part. The actuating element is movable by adjusting the grip part for actuating the closing device, for example a door lock of a vehicle door, such that by adjusting the grip part via the actuating element, an actuating force is transmitted to the locking device via a suitable transmission means, for example in the form of a Bowden cable or linkage, and the locking device thus can be operated.

In the case of door lock arrangements in vehicle doors, there is the fundamental requirement that no unlocking of the vehicle door is allowed in the event of a crash, because opening a vehicle door, for example in the case of a car overturning, could lead to a vehicle occupant being thrown out and thus contribute to a considerable increase in the risk of injury.

BESTÄTIGUMGSKOPIE One possible reason for opening a vehicle door as a result of an undesired lock actuation may be that, in the event of a crash, the door handle is unintentionally moved and the door lock arrangement is unlocked. There is therefore the fundamental need to minimize the risk of accidental operation of a door handle as far as possible in the event of a crash.

In a crash - especially in a side impact on a vehicle side door - inertia forces act on the door handle, which may also act in an opening direction, in which the door handle is to adjust the operation of the door lock. In order to avoid an inertial actuation of the door handle in such a crash, conventionally balancing mass elements are provided which compensate for acting in the direction of an opening direction of the door handle inertial forces and thus prevent the door handle can be actuated due to acting in the opening direction inertial forces.

If a single balancing mass element is provided, this counteracts in particular those inertial forces which are directed exactly along the opening direction of the door handle, along which the door handle is to be moved in order to actuate the door lock. Such a balancing mass element thus has a particularly reliable effect in the event of a crash in which a vehicle is struck from the side of the impact.

In order to additionally be able to intercept inertia forces that occur at a shock that does not take place exactly laterally, it is also possible to use a plurality of balancing mass elements which are arranged at an angle to one another and can thus compensate for inertial forces in different directions. However, such arrangements have the disadvantage that they require an increased space requirement and also increase the weight of the actuator. In any case, balancing mass elements require fine tuning in order to be able to ensure sufficient crash safety.

Based on this, there is a need for security devices that can prevent any kind of crashes in a safe and reliable manner actuation of a handle portion of an actuator to prevent in a crash, for example, opening a vehicle door due to the acting crash forces. The object of the present invention is to provide an actuating device and a method for actuating a locking device, which can reliably prevent an unwanted operation in the event of a crash. This object is achieved by an article having the features of claim 1.

Accordingly, in an actuating device operatively connected to the actuating element securing device is provided which has a mass element and a locking device, wherein the mass element is arranged on a connected to the actuating element, in an adjustment of the handle part together with the actuating element moving transfer means is arranged and

- In a normal operating state with a movement of the actuating element, the mass element and the locking device along an adjustment direction are movable relative to each other and

- In an exceptionally loaded state in which the mass element and the locking device are displaced in a direction transverse to the adjustment relative to each other, a relative movement of the mass member and the locking device along the adjustment direction is locked so that the actuating element is not movable for actuating the locking device.

The present invention is based on the idea to use in an actuator, an additional safety device having a mass element and a locking device, which are movable relative to each other by the action of crash forces. The mass element and the locking device must work together in such a manner that in a normal operation state under normal ^'use of the actuator relative movement of the mass member and the lock device is possible in a direction of adjustment easily. In a crash, however, the mass element and the locking device are shifted due to acting crash or inertial forces transversely to the adjustment against each other, so that the mass element and the locking device can not (more) in the adjustment to each other can be adjusted and the locking device can not be operated unintentionally.

Upon normal operation of the operating device in the normal operating state, the mass member and the locking means are moved along the displacement direction (which is preferably different from the opening direction of the grip part of the operating device) when the operating member is displaced due to operation of the grip part. In the exceptionally loaded condition, ie in a crash, however, there is a deflection and possibly oscillation of the Mass element relative to the locking device transverse to this adjustment, so that due to this shift, the relative movement of the mass element and the locking device is locked. The use of such a mass element in conjunction with a locking device has the advantage that in a crash, a deflection of the mass element relative to the locking device in all directions transverse to the adjustment, along which in the normal operating state, the mass element is moved relative to the locking device can take place , By deflection in any direction transverse to the adjustment direction thus acting in a crash crash and inertial forces are absorbed, with each deflection of the mass element due to a crash or inertial force that does not act exactly along the adjustment, blocking the relative movement of mass element to blocking element causes and thus an actuation of the actuating element is blocked.

It should be noted at this point that a deflection in a crash occurs regularly dynamically and the mass element and / or the securing device can also be set in vibration due to a pulse-like crash load, which lead to a deflection and consequently to a locking of the securing device.

The adjustment direction, along which the mass element and the locking device can be moved to each other when the actuating element is adjusted, is preferably different from the opening direction in which the handle part is moved during normal operation. The adjustment direction may, for example, be directed along the force flow direction, in which actuation forces are transmitted from the actuation element of the actuation device to a closure device.

The actuating device advantageously has a bearing bracket on which the grip part and the actuating element are arranged and by means of which a compact modular unit to be installed is created. The securing device can likewise be arranged on the bearing bracket or also on the locking device or on another component in the power transmission line between the actuating device and the locking device, for example in a force-transmitting Bowden system. The mass element is arranged on a transmission means connected to the actuating element, for example a traction means transmitting exclusively tensile forces in the form of a cable or a rigid coupling linkage. The fact that the mass element is arranged on a directly connected to the actuating element transmission means which is moved when adjusting the handle part together with the actuating element, it is ensured that a movement of the actuating element is locked before it enters. Characterized in that the transmission means is operatively connected directly to the actuating element, a movement of the actuating element is accompanied by a movement of the mass element, which is blocked in a crash.

The transmission means may in this case for example be between the actuating element and a fixed portion on which the actuating element is movably arranged, and be resiliently held on the fixed portion. Alternatively, it is also possible to arrange the mass member on a transmission means used for transmitting the operating force from the operating member to the shutter and extending between the operating member and the shutter. In the first case, an additional transmission means is used, which is stretched between the actuating element and the fixed section, for example the bearing bracket, and supports the mass element. In the second case, the already existing transmission means, which extends between the actuating element and the closing device for transmitting actuating forces, is used, so that no additional cable or the like has to be inserted.

Characterized in that the mass element is arranged at a between the actuating element and the fixed portion or between the actuating element and the closing device extending transmission means, the mass element transversely to the extension direction of the transmission means corresponding to the adjustment of the mass member relative to the locking device during normal operation of the actuator to be deflected. In a normal operating state, the mass element and the locking device are not deflected in this case and can thus be moved relative to one another during actuation of the actuating element, for example by pulling on the transmission means in the adjustment direction. If crash forces act in the event of a crash, the mass element, on the other hand, becomes transverse to the adjustment direction, that is to say transversely to the direction in which the transmission medium extends, deflected relative to the locking device, so that a relative movement between the mass element and the locking device is locked in the adjustment.

In particular, the barrier device may form an opening which in the normal operating state is arranged relative to the mass element in such a way that the mass element can be moved through the opening in order to displace the mass element and the barrier device relative to each other along the adjustment direction. In the exceptionally loaded state, in which the mass element is deflected relative to the locking device transversely to the adjustment direction, the mass element, however, can not be moved through the opening, so that a relative movement between the mass element and the locking device is locked and accordingly the actuating element not Actuation of the locking device can be adjusted. The opening of the locking device may be formed in a first specific embodiment of a vibrating body of the locking device, wherein the vibrating body, for example in a plane transverse to the adjustment pivoted e.g. can be arranged on the bearing bracket via an axle. In the event of a crash, on the one hand, the mass element and, on the other hand, the oscillating body can be moved due to the inertia and crash forces acting, the deflection of the mass element on the one hand and the oscillating body on the other being different and thus, in the deflected state of the mass element and / or the oscillating body, the mass element can not be adjusted along the adjustment relative to the vibrating body and thus a relative movement of mass element and vibrating body is blocked along the adjustment.

In order to ensure that in the normal operating state, the opening of the oscillating body is aligned with the mass element and thus in the normal operating state, the mass element can be moved through the opening of the oscillating body, for example, a spring element may be provided which biases the vibrating body in a rest position, so that in the normal operating state of the vibrating body is held in the rest position. As a result of a load of the vibrating body can then be deflected from the rest position and pivots in this case in a pivoting direction transverse to the adjustment, along which the mass element and the locking device can be adjusted to each other in the normal operating condition. If the blocking device has a vibrating body, then this is advantageously designed and mounted in comparison to the mass element such that in the exceptionally loaded state the vibrating body and the mass element are deflected differently, so that a relative movement of the mass element and the vibrating body along the displacement direction is blocked , The deflection and vibration movement of the mass element and the oscillating body in a crash are thus different, so that it is precluded that the opening on the vibrating body and the mass element are aligned in a crash, and thus ensures that the locking device locks in the event of a crash.

For example, the oscillating body and the mass element may have different masses, wherein additionally or alternatively it is also conceivable to set a (spring) preload in the bearing of the oscillating body and the mass element so that a different deflection is ensured in the event of a crash.

In an advantageous embodiment, the blocking device may have a housing, on which the oscillating body forming the opening is held. In this case, the opening is thus not formed by the housing itself, but by a vibration body held on the housing, which is arranged on the housing, that the oscillating body can be deflected in a plane transverse to the adjustment. This can be achieved in that the oscillating body is held on the housing via at least one spring element, preferably via at least three spring elements, and thus is elastically supported on the housing in a plane transverse to the adjustment direction.

As an alternative to using spring elements for holding the oscillating body to the housing, it is also possible to use one or more molded parts which hold the oscillating body in a rigid manner in a plane transverse to the adjustment direction on the housing.

These moldings can be formed on the walls of the housing and connect the oscillating body with the housing, wherein the mold parts can each have a predetermined breaking point, which is designed such that by breaking the moldings - for example due to acting crash forces - the vibrating body is released from the housing is radially (at least slightly) movable and is then held axially via suitable axial securing elements. The use of such moldings allows the manufacture of the housing and the oscillating body in one-piece construction in a single operation and tool, for example by means of plastic injection molding. As an alternative to the one-piece design, the molded parts can also be fastened to the walls of the housing via detachable clip connections, wherein the force required to release each clip connection can be set such that unintentional release is not possible during operation and, in particular, crash forces can be absorbed in the event of a crash However, by applying a sufficiently large, a threshold exceeding force of the vibrating body but can be released from the housing.

In all variants in which a vibrating body is held rigidly or elastically in a plane transverse to the adjustment direction on the housing, one or more axial securing elements can additionally be arranged on the housing, which also support the vibrating body in relation to a displacement along the displacement direction relative to the housing and thus fix the oscillating body axially to the housing. This Axialsicherungselemente may be formed, for example, as projections which rest axially on the oscillating body and thus support the oscillating body axially.

In another embodiment, the locking device may also have a housing on which the opening is formed directly. The opening may in this case be formed, for example, by one or more mold parts which are arranged on walls of the housing, wherein the mold parts delimit the opening and are arranged rigidly on the housing.

By using a housing, the locking device can be configured as largely modular unit, which can be attached to the bearing bracket or other component, for example, by being clipped to the bearing bracket or the other component.

The actuating element can be pivoted, for example, about a pivot axis and coupled via a coupling rod with the handle part such that upon an adjustment of the handle part, the actuating element is pivoted about its pivot axis. In this case, advantageously, in addition a balancing mass element is connected to the actuating element, wherein the balancing mass element is formed and provided to counteract an inertial force induced adjustment in a crash. The balancing mass element is advantageously adjusted so that inertial forces which act on the grip part along the adjustment direction are intercepted. An inertial force-related actuation of the handle portion in a crash is thus further complicated because as backup systems on the one hand the balancing mass element and on the other hand, the safety device using the mass element and the locking device and thus provide a redundant backup against accidental actuation of the locking device in a crash.

The object is further achieved by a method for actuating a locking device of a vehicle using an actuating device of the type described above. In such a method it is provided that the mass element is arranged on a connected to the actuating element, in an adjustment of the handle part together with the actuating element moved transmission means and

- In a normal operating state during a movement of the actuating element, a mass element and a locking device of an operatively connected to the actuating element securing device along an adjustment direction are moved relative to each other and

- In an exceptionally loaded state in which the mass element and the locking device are displaced in a direction transverse to the adjustment relative to each other, a relative movement of the mass member and the locking device along the adjustment is locked so that the actuating element is not movable for actuating the spit device. For advantages and advantageous embodiments of such a method, reference should be made to the above.

The idea underlying the invention will be explained in more detail with reference to the embodiments illustrated in the figures. Show it:

1 shows a schematic view of a vehicle door 1 which, in a manner known per se, has a door handle 2 with an adjustable handle part 20 which can be actuated to open the vehicle door 1.

As shown schematically in FIG. 2, a handle part 20 of this kind can be arranged, for example, pivotably about a pivot axis 200 on the vehicle door 1 and be coupled via a coupling point 22 connected to the handle portion 20 coupling rod 22 via a pivot point 221 with a lever member 23. The lever member 23 is pivotally mounted about a pivot axis 230 on a bearing bracket 21 and is fixedly connected to an actuating element 25, which on a traction means 300 of a Bowden 30 acts for connection to a closing device 3 in the form of a door lock of the vehicle door 1.

The lever element 23 is arranged pivotably about the pivot axis 230 on the bearing bracket 21 and can be moved by adjusting the door handle 20 such that the actuating element 25 exerts an actuating force on the traction means 300 and thereby actuates the locking device 3 for opening the vehicle door 1. If the handle part 20 is adjusted accordingly in an opening direction V1, then the lever element 23 is pivoted together with the actuating element 25 into an adjusting device V2, thereby pulling the traction element 300 an adjustment direction V3, so that an actuating force is transmitted to the closing device 3 via the traction means 300 and the Closing device 3 is actuated.

A basic requirement in a door handle 2 of the kind shown schematically in FIGS. 1 and 2 is that in a crash there may not be an accidental operation of the door handle 2, which could lead to unlocking of the locking device 3 and the opening of the vehicle door 1 , For this purpose, it should be provided in particular that due to inertial forces acting on a lateral collision, the grip part 20 can not be automatically and unintentionally moved in the opening direction V1 because otherwise this could result in an actuation of the actuation element 25 and an unlocking of the closure device 3.

In order to counteract such inertial forces, a balancing mass element 24 is provided as the first safety measure in the arrangement shown schematically in Fig. 2, which is arranged at one of the articulation point 221 opposite end of the lever member 23, so that the articulation point 221 and the balancing mass element 24 - related on the pivot axis 230 of the lever member 23 - are arranged at different ends of the lever member 23. The balancing mass element 24 serves to counteract inertial forces acting on the lever element 23 in the event of a side crash and causing a torque in the direction of an opening of the grip part 20, by generating an opposing torque which compensates or even overcompensates a torque occurring due to inertia, so that the handle 20 is not automatically adjusted. In an illustrated in Fig. 3, a specific embodiment of a door handle 3, analogous to the embodiment shown schematically in Fig. 2, on a bearing bracket 21, a lever member 23 about a pivot axis 230 pivotally mounted, wherein the lever member 23 integrally with an actuating element 25 for coupling with a Pulling means 300 is formed. The lever member 23 is connected via a pivot point 221 at one end to a handle portion 20 (not shown in Fig. 3) and carries at its other end a mass balance element 24 which - relative to the pivot axis 230 - the pivot point 221 opposite.

The operation of the arrangement according to FIG. 3 is described in the same way as above with reference to FIG. 2. If the lever element 23 is pivoted about the pivot axis 230 in an opening direction V1 via a grip part, the actuating element 25 moves in the adjustment direction V2 about the pivot axis 230 and pulls the traction means 300 in the adjustment direction V3, so that a locking device coupled to the traction means 300 is pressed.

The actuating element 25 is formed in the embodiment according to FIG. 3 by coupling elements 250, 251, which are formed integrally with the lever element 23 and are thus pivotable together with the lever element 23 about the pivot axis 230. With one coupling element 250 while the traction means 300 is connected, while on the other coupling element 251 an additional securing device 4 attacks, which provides an additional safeguard against unwanted adjustment of the actuating element 25 in the event of a crash.

The additional securing device 4 includes - in the embodiment shown in FIG. 3 - as essential components a mass element 41 on a transmission means 40 in the form of a pull rope and a locking device 42 in the form of a vibrating body 423 which is pivotally mounted on the bearing bracket 21.

The transmission means 40 in the form of the tension cable is in this case attached with its one end 400, which is formed as a hook, via a spring element 402 to a mounting portion 210 of the bearing bracket 21 and engages via its other end 401 on the coupling element 251 of the actuating element 25 so the transmission means 40 is clamped between the fastening section 210 of the bearing bracket 21 and the coupling element 251 of the actuating element 25.

The vibrating body 423 is, as the enlarged views of FIGS. 4 and 5 can be seen, pivotally mounted with an axle 422 in locking elements 212 on the bearing bracket 21 and is arranged between support portions 21 1 in the form of projections on the bearing bracket 21 such that the oscillating body 423 can be pivoted about the axle element 422 in a pivoting direction S1. The oscillating body 423 has a U-shaped and downwardly open opening 420, which is penetrated by the transmission means 40 and has a light width which is (slightly) larger than the diameter of the mass element 41. The securing device 4 serves to block an actuation of the actuating element 25 in the event of a crash, without, however, impairing the actuation of the actuating element 25 in a normal operating state in which no crash forces act. The operation of the securing device 4 is as follows.

In a normal operating state, the transmission means 40 extends through the opening 420 of the oscillating body 423 such that when the actuating element 25 is actuated to open the closing device 3 (as a result of which the coupling element 251 pivots in the adjusting direction V2 according to FIG ), the transmission means 40 in an adjustment direction V4 approximately rectilinearly adjusted and the mass element 41 is moved through the opening 420. The oscillating body 423 is held in the normal operating state in a rest position, caused by a arranged on the axle 422 spring element 421, which biases the vibrating body 423 elastically relative to the bearing bracket 21.

In a normal operating state, the actuating element 25 can thus be readily moved without this being prevented by the securing device 4.

In the event of a crash, on the other hand, as a result of the forces acting in the event of a crash, the mass element 41 and / or the oscillating body 423 deflects. The mass element 41 can move in all spatial directions transversely to the adjustment direction V4 (corresponding to the directions of movement S2 according to FIG. 5). while the oscillating body 423 can perform a movement along the direction of movement S1 about the axle 422 transversely to the adjustment direction V4. If, in the event of a crash, there is a shock and, correspondingly, the occurrence of inertial forces on the mass element 41 and the oscillating body 423, the mass element 41 and / or the oscillating body 423 deflect (at least whenever the inertial forces are not exactly along the mass) Adjusting direction V4 act), so that the oscillating body 423 and the mass element 41 move relative to each other and upon actuation of the actuating element 25, the mass element 41 is not (anymore) the opening 420 can be guided because the mass element 41 abuts against the oscillating body 423.

In order to prevent the mass element 41 and the oscillating body 423 from being deflected in exactly the same way, the masses of the mass element 41 and the oscillating body 423 as well as the spring preload of the spring element 402 (for prestressing the transmission means 40) and the spring element 421 (for prestressing of the oscillating body 423) can be suitably adjusted in such a way that the deflection takes place in a different way in the event of a crash.

As can be seen from FIG. 3, the transmission means 40 extends approximately in the same direction as the traction means 300 extended by the coupling element 250 and perpendicular to the opening direction V1, into which the gripping part 20 for actuating the door lock 3 is to be moved. The securing device 4 thus blocks in particular in the event of a side crash (with a thrust direction along the opening direction V1), but also in other thrust directions which are directed at least with one direction component transversely to the adjustment direction V4 of the traction mechanism 40 and thus lead to an inertia-related deflection of the mass element 41 and / or the vibrating body 423 lead.

FIGS. 6 and 7A-7C show a further embodiment of a securing device 4, in which a securing device 4 with a modified blocking device 42 'is provided. The locking device 42 'has a housing which is formed with six interconnected by film hinges walls 42 A'-42 F 'and on the insides of the four longitudinally extending walls 42 A'-42 D 'moldings 420' carries, which together form an opening 421 ' , In a normal operating state of the actuating device 2, upon actuation of the actuating element 25, the mass element 41 can be moved along the adjusting device V4 through the opening 421 ', so that an actuation of the actuating element 25 is not impaired or even blocked. However, if, as described above, the mass element 41 is deflected in a spatial direction transverse to the adjustment direction V4 relative to the opening 421 'in a crash, the mass element 41 strikes at attempted actuation of the actuating element 25 on one or more of the mold parts 420' , so that a movement of the mass element 41 and, associated therewith, the transmission means 40 in the Adjustment direction V4 prevents and thus actuation of the actuating element 25 is locked.

At the housing formed by the walls 42A'-42F 'are frontally a passage opening 424' for attaching the transmission means 40 by means of the spring member 402 to the mounting portion 210 of the bearing bracket 21 (wall 42E ') and a slot 423' and an opening 422 'to Insertion of the transmission means 40 arranged (wall 42 F '). By providing the box-shaped housing, a modular unit can be created, which can be attached in a modular manner to the bearing bracket 21 and clipped example, with the bearing bracket 21.

In the embodiments according to FIGS. 3-5 and FIGS. 6, 7A-7C, an additional transmission means 40 is provided, which is connected separately from the transmission means 300 to the actuating element 25 and clamped between the actuating element 25 and the bearing bracket 21.

In an embodiment shown in Figs. 8 and 9, a securing device 4 is arranged on the transmission means 300 for connecting the actuating element 25 to the closure device 3 having a housing formed by walls 42A-42F integral with the longitudinally extending walls 42A "-42B" formed spring elements 420 "a vibrating body 425" carries, which surrounds the transmission means 300 circumferentially.

The mode of action of the securing device 4 according to the exemplary embodiment according to FIGS. 8 and 9 is analogous to that described above. In a normal operating state, a mass element 41 arranged on the transmission means 300 can be moved through an opening 427 "of the oscillating body 425" in the adjustment direction V3, along which the transmission means 300 is moved rectilinearly upon actuation of the actuating element 25, so that an actuation of the Actuator 25 is not affected. If, however, the mass element 41 and / or the oscillating body 425 "are deflected transversely to the adjustment direction V3 in the event of a crash, movement of the mass element 41 through the opening 427" of the oscillating body 425 "is not possible, so that the safety device 4 moves the traction means 300 blocks and accordingly prevents actuation of the actuating element 25. The mass element 41 arranged on the transmission means 300 acts directly in the direction of the force flow of the traction means 300 and thus directly blocks the force flow for actuating the closing device 3. Analogously to the above described embodiment with reference to FIGS. 3-5, the spring elements 420 " to tune the voltage of the transmission means 300 and the masses of the mass element 41 and the oscillating body 425 "so that the deflection of the mass element 41 and the oscillating body 425" in a crash does not take place similarly and thus in a crash to a relative movement between the mass element 41st and the oscillating body 425 "transversely to the adjustment direction V3 comes.

As can be seen from FIG. 9, axial securing elements 424 "are additionally provided on the longitudinally extended walls 42A" -42D "on both sides of the oscillating body 425", axially axially aligning the vibrating body 425 "along the adjusting direction V3 on the housing formed by the walls 42A" -42F " set so that the vibrating body 425 "can move only in a plane transverse to the adjustment direction V3 in the housing. As can also be seen from FIG. 9, slits 422 ", 423" are provided on the front-side walls 42E ", 42F", through which the transmission means 300 can grip and enable the housing to be attached to the transmission means 300.
