Description

The present invention is directed to a door handle unit for operating a lock of a movable part of a motor vehicle, in particular a door, flap or the like according to the preamble of claim 1.

In this case, the door handle unit has a door handle which is movably mounted on a carrier element for the mechanical opening of the movable part by a user, the door handle being able to assume at least one rest position and one working position. Furthermore, the door handle unit is provided with a mechanical coupling element which is movably mounted on the carrier element and by means of which a movement of the door handle from the rest position to the working position can be transferred to the lock, the door handle and the coupling element interacting mechanically and forming a movable actuating mechanism. Furthermore, the door handle unit has at least one locking unit, which in the normal case allows a movement of the actuating mechanism to operate the lock and only in a locked case a movement of the Actuating mechanism for actuating the lock blocked. Furthermore, the present invention is also directed to a method for securing a door handle unit according to the preamble of claim 14.

Door handle units of the generic type are known from the prior art which are provided with a crash lock or a crash latch. In this context z. B. the Offenlegungsschrift DE 199 29 022 A1 to be mentioned, which discloses a crash lock for a generic door handle unit. The special feature of this crash barrier is that it is provided with a low mass, so that it can be moved faster than heavier moving parts of the door handle unit due to the lower mass inertia. If accelerations now act on the door handle unit as a result of a crash, these cause the nimble crash barrier to block the other, heavier, moving parts of the door handle unit with a positive fit. It can thus be avoided that the door handle unit can be triggered incorrectly in the event of an accident and the resulting accelerations.

However, it has been found in numerous accident investigations that such crash barriers can also flutter, so that the door handle unit can still be unintentionally triggered, but this must be avoided in any case. In the case of the aforementioned crash lock for the door handle unit, it does not matter whether the movable door handle itself is actually set in motion or not, since the crash lock is actuated exclusively due to the forces from the crash accelerations that act directly on the crash lock.

The object of the present invention is therefore to provide a door handle unit and a method for securing a door handle unit which has improved safety, in particular in the event of a crash or in the event of an accident. In particular, it is the object of the present invention to directly block the movement of the actuation mechanism comprising the door handle and the coupling element if these should move unintentionally in the event of a crash.

The present object is achieved by a door handle unit for operating a lock of a movable part of a motor vehicle, in particular a door flap or the like with the features of claim 1, in particular from the characterizing part, solved. A method for securing such a door handle unit with the features of claim 14, in particular from the characterizing part, is also proposed to achieve the object. Preferred developments of the invention are listed in the dependent device and method claims. Features that are disclosed for the door handle unit according to the invention also apply to the security method according to the invention and vice versa. In addition, the method according to the invention from claim 14 can be implemented with the door handle unit according to the invention. Advantageous configurations of the door handle unit according to the invention and the method according to the invention are listed in the dependent claims.

In the case of the door handle unit according to the invention, it is provided that the locking unit can be activated by an unusual movement of the actuating mechanism for a locking event. Thus, the locking unit is not activated by the crash itself, but only in the case when the actuating mechanism performs an unusual movement. The locking unit is thus activated by the movement of the actuating mechanism and not by the accelerations acting on the door handle unit that are present in the event of a crash. An extraordinary movement of the actuating mechanism is understood within the scope of the invention to mean that it is jerky and / or fast. Consequently, extraordinary movement does not rely on normal movement of the door handle to open the moving part such as the door or flap. However, the locking unit is also activated, that is, without an accident when a user z. B. is torn or pulled jerkily on the door handle. In such a case, the crash barrier, as described in the publication DE 199 29 022 A1 do not lead to a blocking of the movement mechanism, since no direct accelerations act on the crash barrier. It is thus clear that the present locking unit is not activated causally by the crash acceleration that acts on a vehicle in the event of a crash, but rather by the actual relative movement of the actuating mechanism to the carrier element or movable part. The extraordinary movement is thus based exclusively on a movement of the actuating mechanism relative to the carrier element or moving part. A normal movement of the door handle by its user, however, does not lead to an activation of the locking unit, so that the entire door handle unit is fully usable and functional. The case described above is the normal case when the door handle unit is operated.

In the case of the door handle unit according to the invention, it is thus provided that the locking unit has at least one movable pawl which blocks the actuating mechanism in a form-fitting manner when it is locked. Here, the resulting form fit can be implemented in particular between the pawl and the carrier element or the movable part, in particular a shoulder or a projection thereof. Thus, the door handle unit according to the invention is securely blocked by the resulting form fit in the activated state of the locking unit. This also rules out any further movement of the actuation mechanism, so that false triggering cannot occur.

Furthermore, it is provided within the scope of the door handle unit according to the invention that at least one locking pawl can be transferred from its release position into its locking position by a release force. The locking unit is normally in the release position, so that the door handle unit according to the invention can be operated normally in order to be able to open the lock on the movable part. The locking unit is in the locked position in an emergency (the so-called locking case), so that the locking pawl blocks the actuating mechanism in a form-fitting manner. Normal actuation of the actuating mechanism is thus excluded, so that the lock on the moving part cannot be opened. The aforementioned release force results from the extraordinary movement of the actuating mechanism, which leads to a pivoting and / or rotating movement of the locking unit. As a result of this pivoting and / or rotating movement of the locking unit, a centrifugal force acts, in particular on the locking pawls, so that the centrifugal force represents the triggering force for the pawls. Due to the action of the release force, the pawls are transferred from their release positions to their locked positions by turning. In the locking position, a mechanical stop is provided for each locking pawl so that it is not overturned and remains in the locking position at least during the action of the release force.

It is also conceivable within the scope of the invention that at least one locking pawl is supported by the locking unit in the release position, loaded by a spring element. By this spring element pushes the pawl into the release position. In the case of locking, the release force acts on the locking pawl in such a way that it counteracts the spring force of the spring element and transfers the locking pawl from the release position into the locking position. The corresponding spring element can be designed as a leaf or torsion spring and in particular around a pivot point of the pawl.

According to the invention, at least one pawl of the locking unit is locked in the locking position by a latching connection when changing from the release position to the locking position. The locking unit thus permanently blocks actuation of the actuating mechanism by means of the positive fit produced, so that inadvertent triggering of the lock to open the movable part is prevented in a secure manner. In this embodiment, however, after a single triggering or activation of the locking unit, the door handle unit can no longer be actuated by the door handle in order to be able to open the lock for the movable part. However, this embodiment has the advantage that fluttering of the locking unit according to the invention is reliably prevented, since the locking pawl is irrevocably positively blocked by the existing latching connection.

According to the invention, one or more locking units can be provided for the door handle unit. A locking unit can have one or more locking pawls. A locking unit can also have a modular structure, so that it can e.g. B. can be clipped to the operating mechanism. It is also conceivable that the locking unit is let into a receptacle in the actuating mechanism, whereby the full function of the handle unit according to the invention can be produced.

Furthermore, the door handle unit according to the invention can also additionally have at least one crash barrier, as in the prior art DE 199 29 022 A2 described, have. In addition, it is expedient if the door handle unit according to the invention also has a mass balancing weight, which ideally is mechanically connected or even integrated with the coupling element.

In the case of the door handle unit according to the invention, it can be provided that the locking unit is attached directly to or with the actuating mechanism. Thus, no additional transmission element is necessary to move the locking unit, since it is directly connected to the actuating mechanism and thus the movement of the actuating mechanism also acts directly on the locking unit.

It is also conceivable that the locking unit is indirectly connected to the actuating mechanism and interacts mechanically via a transmission element. If the locking unit is indirectly connected to the actuating mechanism, it can have a separate housing in which a movable rocker is arranged around a pivot point or an axis of rotation. Ideally, the housing is arranged in a stationary manner on the door handle unit or the movable part. The previously described "T" -shaped rocker is then rotatably mounted on or in the housing within the housing. Furthermore, at least one shoulder is provided in the housing, with which the pawl interacts in a form-fitting manner when it is locked or in its locked position. At least one pawl, preferably two pawls, is then arranged on the rocker, which in the locked position enter into the desired form fit, in particular with a shoulder in the housing. The movement of the actuation mechanism can be transmitted to the rocker of the locking unit via a transmission element, the transmission element preferably being designed as a Bowden cable or chain or the like. The advantage of the indirectly attached locking unit is that it can be arranged at any point on the door handle unit or even from the movable part.

In the case of the indirect arrangement of the locking unit with the actuating mechanism, it is also conceivable that the actuation mechanism is not only moved to the locking unit via the transmission element, but that a transmission unit, in particular in the form of a gear, is also provided. This can the gear ratio can be optimized to e.g. B. to achieve rapid activation of the locking unit based on a minimal movement of the actuating mechanism. The aforementioned transmission can be designed as a lever mechanism, gear mechanism or the like, in order to change the transmission ratio of the movement from the actuating mechanism to the locking unit.

The present object of the invention is also achieved by a method for securing a door handle unit according to the preamble of claim 14. It is provided according to the invention that the locking unit is activated in the event of a locking event by an extraordinary movement of the actuating mechanism. The method according to the invention can be carried out with the door handle unit according to the invention according to claims 1 to 13.

Further measures and advantages of the present invention emerge from the claims, the following description and the drawings. The disclosed features from the door handle unit according to the invention also apply to the method according to the invention and vice versa. In the drawings, the invention is shown in different embodiments.

In the figures, the same reference symbols are used for the same technical features also for different exemplary embodiments.

In the Figures 1a to c the functioning of the door handle unit 10 according to the invention is shown schematically. It shows Figure 1a a coupling element 13 of the actuating mechanism 15, which is rotatably mounted about an axis of rotation 13.1. In addition, a receptacle 13.4 is provided on the coupling element 13, whereby a triggering means 21, which in Figure 2 is shown as a Bowden cable and serves as a transmission means for the lock 101, can be mechanically coupled for mechanical actuation of the lock 101. By rotating the coupling element 13 around the pivot point 13.1, the release means 21 is actuated, whereby the lock 101 is mechanically actuated, whereby a movable part 100, which is designed as a door flap or the like on the motor vehicle 100, can be opened. The coupling element 13 can be provided with a mass balance weight 14, as in FIG Figure 2 is shown. It is also conceivable, however, that the coupling element 13 is a represents a separate component for the coupling element 13. The mass balance weight 14 serves to balance and at least partially compensate for the mass inertia forces acting on the door handle unit 10, in particular the movable door handle 11 in the event of a crash, in order to prevent the door handle 11 from being accidentally removed from the vehicle in the event of a crash Rest position is moved into its working position by the forces of acceleration of the crash.

In the Figures 1a and 1b is the normal case la with a normal, proper actuation of the door handle 11 and thus the generated movement of the actuating mechanism 15 with the coupling element 13 and possibly the balancing weight 14 is shown. In this normal case la, a locking unit 16 according to the invention is also in its release position IIa, in which the locking unit 16 is virtually inoperative and enables the actuating mechanism 15 to move unhindered to actuate the lock 101. Based on the Figure 1a , in which the rotatably mounted coupling element 13 is in a rest position of the door handle 11, this coupling element 13 rotates by actuation of the door handle 11 between the rest position into the working position, around the pivot point 13.1, whereby the coupling element 13 this rotary movement to operate the lock 101 uses. With this rotation of the coupling element 13 in the normal case, the locking unit 16 remains virtually inoperative, ie it is not activated. In contrast to the two Figures 1a and 1b is in Figure 1c a comparable illustration of the coupling element 13 is shown, in which the rotational movement is blocked by the two existing locking units 16 in a form-fitting manner 18. This means that further rotation of the coupling element 13 about the pivot point 13.1 is no longer possible, since the two locking units 16 that are present block this further rotation through the positive fit 18 produced.

As in the Figures 1a to c It can also be seen that in the present case of the door handle unit 10 according to the invention, a total of two locking units 16 are arranged at a distance from the pivot point 13.1 of the coupling element 13. In the present case, these two locking units 16 are approximately the same distance from the pivot point 13.1 and are arranged on different sides of the coupling element 13. A locking unit 16 itself has a rotatable or pivotable locking pawl 16.1, which is mounted directly to the coupling element 13 via a rotation axis 16.4. In the Figure 1a and 1b the respective pawls 16.1 of the locking units 16 are shown in their release positions IIa. In addition, the Figure 1a a spring element 16.2 is shown for the respective pawl 16.1. This spring element 16.2 exerts a spring force on the pawl 16.1 in order to press it into the release position IIa. How with the Figure 1a can be seen, the spring element 16.2 is designed as a spiral spring, which interacts mechanically with corresponding stops on the coupling element 13 and the respective pawl 16.1. In addition, the Figures 1a to 1c Optional latching connections 17 between the respective pawl 16.1 and the coupling element 13 are also shown. This latching connection 17 is realized by way of example by a latch 17.1 on the pawl 16.1, which interacts mechanically or positively with an opening 17.2 in the coupling element 13 or the actuating mechanism 15. By rotating the pawl 16.1, the catch 17.1 slides along the edge of the opening 17.2 until it locks in a form-fitting manner behind the edge of the opening 17.2. It is therefore no longer possible for the pawl 16.1 to be moved back from the rotated blocking position IIb into the release position IIa. The additionally provided spring element 16.2 is also unable to move the pawl 16.1 from this blocking position IIb into the release position IIa by the corresponding spring force. However, the additional spring element 16.2 ensures that the pawl 16.1 does not unintentionally change from the release position IIa to the blocking position IIb.

How out Figure 1b It can also be seen that proper actuation of the door handle 11 does not cause the locking unit 16 to be activated. In this normal case 1 a, only an ordinary movement of the actuation mechanism 15 takes place. In this case, the locking unit 16 remains inactive and remains in its release position IIa. How with the Figure 1b can be seen, thus move the beveled ends of the L-shaped pawls 16.1 along the shoulders 12.1 provided for this purpose and do not touch them. The paragraphs 12.1 are themselves arranged in a stationary manner on the carrier element 12 or the movable part 100 and in the blocking position IIb cooperate with the respective pawl 16.1 in a form-fitting manner. However, as already said, the two L-shaped pawls remain in the Figure 1b in their release position IIa and thus do not touch the provided paragraphs 12.1, so that overall the locking units 16 remain inactive.

In the Figure 1c the coupling element 13, which forms part of the movable movement mechanism 15, is shown in the event of an extraordinary movement of the actuation mechanism 15. During this extraordinary movement, the actuating mechanism 15 rotates at a certain speed, so that a corresponding resulting release force 110 from the centrifugal force present acts on the rotatably mounted pawls 16.1. By the release force 110, the respective pawl 16.1 is rotated about its pivot point 16.3 or the axis of rotation 16.4 provided for this up to its locking position IIb. In this blocking position IIb, the pawl is held in a form-fitting manner by a stop element, so that further rotation of the pawl 16.1 beyond its blocking position IIb is not possible. Due to the low mass of the respective pawls 16.1, they immediately rotate about their axis of rotation 16.3 as soon as there is an unusual movement of the actuating mechanism 15.

How now with the Figure 1c It can also be seen that the rotated pawls 16.1 in their locking positions IIb correspond positively to the respective paragraphs 12.1 provided on the carrier element 12. A form fit 18 is formed between the locking pawls 16.1 in the locking positions IIb and paragraphs 12.1. The actuation mechanism 15 cannot be rotated any further due to the positive locking 18, which means that actuation of the mechanical lock 101 is no longer possible, since the previous movement of the actuation mechanism 15 is insufficient to be able to actuate the lock 101. In this way it is ensured that an unintentional opening of the lock 101 is reliably prevented by the locking unit 16 present. Due to the locking connection 17 provided, it can be achieved according to the invention that the pawls 16.1 can no longer be transferred from their locking position IIb into the release position IIa. The previously described mode of operation of the locking unit 16 according to the invention with the locking pawl 16.1 when interacting with the paragraph 12.1 is the same in each of the exemplary embodiments, so that it is not described again in the following.

In the Figure 2 the door handle unit 10 according to the invention is shown purely schematically with its essential elements and components. The movable door handle 11 is designed as a pull handle in the direction of arrow 120. However, this can be the case movable door handle 11 can also be an actuating shell or a rotary pull handle or the like. The movement of the door handle 11 is transmitted via a shoulder 11.1 on the door handle 11 to a driver 13.3 of the coupling element 13. This produces a rotary movement of the coupling element 13 about the axis of rotation 13.1 or the pivot point 13.1. This pivot point can also represent a center point between the two pivot points 16.3 of the two locking units 16. In the present case, the locking unit 16 has a modular design and is arranged in a recess in the coupling element 13. The two pawls 16.1 protrude laterally out of recesses in the coupling element 13 in order to be able to produce the desired form fit 18 with the two shoulders 12.1 of the carrier element 12 in the blocking case Ib. The entire door handle unit 10 is fastened to the movable part 100, in particular the inside 100.1, via the carrier element 12. Thus, the two paragraphs 12.1 of the carrier element 12 are also provided in a stationary manner, in particular independently of the actuating mechanism 15 or the coupling element 13 on the door handle unit 10. The corresponding axis of rotation 16.4 for the pawls 16.1 of the locking unit 16 can simultaneously serve as holding elements 16.5 for the modular locking unit 16. For example, screws can serve as holding elements 16.5 and axes of rotation 16.4 here. The mode of operation of the corresponding locking unit 16 has been described in detail above. As further in Figure 2 As can be seen, a pulling movement on the door handle 11 in the direction of the arrow 120 results in a clockwise rotation of the coupling element 13 about the pivot point 13.1. As a result, the release means 21 for the lock 101 is pulled through the corresponding receptacle 13.4 on the carrier element 12 in the direction of the arrow 120. Thus, in the normal case 1 a, the mechanical lock 101 can be opened from its rest position into the working position by actuating the door handle 11.

In the Figure 3 a further embodiment of the door handle unit 10 according to the invention is shown. In this case, the locking unit 16 is indirectly connected via a transmission element 19 to the actuating mechanism 15, with which it interacts mechanically. In this case, the locking unit 16 can be fastened to the carrier element 12 or the movable part 100. The locking unit 16 is preferably accommodated in a housing 16.7 in which a respective shoulder 16.10 is provided for the locking pawls 16.1. This shoulder 16.10 can represent a part of the housing 16.7 or of the carrier element 12 or of the movable part 100. The special thing about this one Lock unit 16 from the Figure 3 can be seen in the fact that this can be coupled as a separate component to an existing door handle unit 10 via the transmission element 19. In addition, the receptacle 13.4 for the release means 21 can also extend from the rocker-like 16.8 locking unit 16 in order to be able to block the mechanical transmission for the lock 101. The transmission element 19 is in the Figure 3 shown as an example as a Bowden cable. In this embodiment, it is also conceivable that a transmission is interposed between the actuating mechanism 15 and the separate locking unit 16 in order to achieve a specific transmission ratio. As mentioned above, this gear mechanism can be designed as a lever mechanism or as a wheel or gear mechanism or the like in order to generate the desired transmission ratio. In the case of the separate locking unit 16, a rotatable rocker 16.8 is used, which is ideally mounted so as to be rotatable about its center of mass 16.9 as a pivot point. Furthermore, two pawls 16.1 are arranged at the same distance from the pivot point 16.3 or center of mass 16.9, if possible. The two pawls 16.1 are also rotatably arranged on the "T" -shaped rocker 16.8 in order to be able to achieve the desired form fit 18 with the aforementioned paragraphs 16.10 in the blocking case Ib.

In the further Figures 4a and 4b a specific embodiment of the door handle unit 10 according to the invention is shown with essential details. The door handle unit 10 has a carrier element 12 which is used to fasten the entire door handle unit 10 to the movable part 100. As with the two Figures 4a and 4b As can be seen, the carrier element 12 is arranged on an inner side 100.1 of the movable part 100 and the movable door handle 11 protrudes through an opening in the movable part 100 on the outer side 100.2. A rotatable coupling element 13 is mounted on the fixedly arranged carrier element 12 via the pivot point 13.1. At the same time, this coupling element 13 also has a mass balance weight 14, so that the two components represent an integrated element. The entire shape of the integrated coupling element 13 is designed in the manner of a lever or rocker, the upper area, which lies above the pivot point 13.1, serving as a driver 13.3 for the movable door handle 11. For this purpose, a recess is provided on the driver 13.3, which interacts positively with a shoulder 11.1 on the door handle 11. In the lower area of the coupling element 13, which is below the pivot point 13.1, is a Locking unit 16 according to the invention is provided with exactly one locking pawl 16.1 which can interact positively with a shoulder 12.1 of the carrier element 12 in the locking case Ib. In the Figure 4a The locking unit 16 according to the invention can also be provided from the different sides of the coupling element 13 in order to improve the stability and security of the door handle unit 10 according to the invention. In the Figure 4a the respective directions of movement 120 for the movable door handle 11 or the rotational movement of the coupling element 13 resulting therefrom are also shown.

In the further Figure 4b FIG. 10 is a three-dimensional view of the door handle assembly 10 of FIG Figure 4a but shown without the movable door handle 11. For better clarification, the locking unit 16 according to the invention is also indicated by dashed lines on the left side of the coupling element 13. A comparable blocking unit 16 can also be arranged on the right-hand side of the coupling element 13, but which is optically hidden by the carrier element 12. Also in the Figure 4b the receptacle 13.4 for the release means 21 is also shown.

In the Figures 4a and 4b the operating mechanism 15 with the door handle 11 is in its rest position. The locking unit 16 according to the invention is also shown in the release position IIa in the normal case la.

In the Figure 5 a vehicle is shown as a motor vehicle 105 in a side view. The two side doors, which each represent a movable part 100, can be clearly seen. The locks 101 provided for this purpose are also shown below the door handle unit 10 according to the invention on the side doors. The door handle unit 10 according to the invention reliably blocks a movement of the actuating mechanism 15 for actuating the lock 100 in the event of a lock.
