door handle device

technical field

The utility model relates to a door handle device of an automobile, especially a car.

Background technique

A vehicle door handle arrangement is known, for example, from DE 10 2005 049 144 A1. The vehicle door handle arrangement comprises a bearing hook which, in the mounted state, is arranged on the inside of the outer surface of the vehicle door. In addition, there is a manually actuatable handle, which is rotatably arranged on the bearing hook, and which passes through the outer surface of the vehicle door in the installed state and is arranged on the outside of the outer surface of the vehicle door. By means of an unlocking device, the hand handle can be connected with the door lock in the installed state, which means that the operation of the hand handle can manipulate the unlocking of the door lock.

The known door handle device has a first inertia locking mechanism (Massensperre), which is balanced by means of a spring and is coupled to the unlocking device in such a way that the outwardly directed acceleration force acting on the door handle device in the mounted state Under certain circumstances, the inertial locking mechanism can hinder or prevent the unlocking operation of the door lock. By means of such an inertial locking mechanism, it is possible to prevent the door from opening in an undesired manner, for example in the event of a collision, when the door is accelerated inwards and deformed so that the inertial force produces an outwardly directed acceleration force as a reaction, which reaction Push the handle outward. In known door handle arrangements for vehicles, the inertial locking mechanism is directly coupled to the handle and generates an inwardly directed holding force on the handle with an outwardly directed acceleration force. In this case, the mass of the first inertial locking mechanism is selected in such a way that it introduces a closing moment (Schliess moment) onto the handle which is greater than the opening moment produced by the acceleration force on the handle .

In addition, the known door handle device is equipped with a second inertia locking mechanism, which is likewise coupled to the unlocking device in such a way that it also blocks or prevents all Describe the unlocking operation of the door lock. In this case, the second inertial locking mechanism interacts directly with a soft-sleeve cable of the unlocking device and limits the force transmission via the soft-sleeve cable. The second inertial locking mechanism has a significantly lower mass than the first inertial locking mechanism, as a result of which a significantly faster response can be achieved than the first inertial locking mechanism. As a result, the responsiveness of the safety of the motor vehicle door in the locked state by means of the inertial locking mechanism can be improved. This fast-response second inertial locking mechanism is advantageous, for example, in the event of a collision, especially on the side of the vehicle avoiding the collision, when the vehicle body experiences shock waves or pressure waves that push the hand Pulling the handle outwards, while at the same time the first inertial locking mechanism may not respond due to its inertia.

Fig. 2 is like the view of Fig. 1, but in the case of a collision.

Detailed ways

According to FIGS. 1 and 2 , the door handle arrangement 1 comprises a bearing hook 2 and a manually actuatable handle 3 . The vehicle door handle device 1 is suitable for use in automobiles, especially in passenger cars. In the installed state, the door handle arrangement 1 is generally located on a vehicle door 4 , which is only partially shown here. The door handle arrangement serves to actuate a door lock, not shown here, which holds the door in the locked position.

In the mounted state shown, the bearing hook 2 is arranged on the inner side of the door outer surface 5 which is clearly shown in FIGS. 1 and 2 . The handle 3 is rotatably placed on the bearing hook 2 . In the mounted state, the handle 3 passes through the outer door surface 5 so that it is arranged on the outer side of the door outer surface 5 . Furthermore, the door handle arrangement 1 also includes an unlocking device 6 , which is shown in simplified form here. In the mounted state, the unlocking device 6 couples the handle 3 to the aforementioned door lock of the door 4 . Therefore, this connection can realize the unlocking of the door lock through the operation of the handle 3 . For example, the unlocking device 6 has for this purpose a soft-sleeve cable 7 which usually has a pressure-resistant hose 8 and a pulling cable 9 extending therein.

Furthermore, the door handle arrangement 1 has a locking element 10 . In the mounted state, the locking element 10 can be switched to an active position by an inward deformation 11 as indicated by the arrow in FIG. 2 . In the active position shown in FIG. 2 , the locking part 10 is engaged with the unlocking device 6 or the locking part 10 is engaged in the unlocking device 6 . The engagement thus makes it possible for the locking element 10 to obstruct or prevent the unlocking operation of the door lock. In principle, the locking element 10 can also interact with the handle 3 in such a way that in the active position of the locking element 10 the unlocking operation of the door lock is hindered or prevented. The switchover of the locking element 10 from the passive position shown in FIG. 1 to the active position shown in FIG. 2 can be effected by the component 12 of the vehicle door 4 . In the event of a crash, preferably a side impact, this component 12 moves as a result of a deformation 11 relative to other components of the vehicle door 4 , for example relative to a bearing hook. The closure part 10 is coupled to such a component part 12 which moves in the event of a crash, so that the movement of the component part 12 can guide the movement of the closure part 10 in a desired manner.

In the preferred exemplary embodiment shown, the locking part 10 is mounted on the bearing hook 2 so as to be rotatable about an axis of rotation 13 . The rotational movement of the locking part 10 is indicated by the rotational arrow 14 in FIG. 2 . In the preferred embodiment shown here, the axis of rotation 13 extends substantially parallel to the vehicle longitudinal direction 18 in the installed state.

Preferably, the locking component 10 is placed on the bearing hook 2 . The corresponding journal thus defines the axis of rotation 13 . This journal is marked with 15 in FIGS. 1 and 2 .

As an alternative to the journal 15, the locking part 10 can also be fastened to the bearing hook 2 via a fastening point. This fixing point is marked with 16 in FIGS. 1 and 2 . In this case, the illustration of the fastening point 16 corresponds to the illustration of the journal 15 . Through the deformation 11 , a deformation is induced in the region of the fastening point 16 . In this case, for example, deformation of the fastening point 16 itself can take place. Additionally or alternatively, the locking part 10 and/or the bearing hook 2 are deformed in the region of the fastening point 16 . The deformation that takes place in the region of the fastening point 16 advantageously takes place in such a way that a rotational movement about the axis of rotation 13 is enabled.

Alternatively, the locking part 10 is also fastened to the bearing hook 2 via a cleavage groove 17 , which is shown in FIGS. 1 and 2 with the same symbols as the fastening point 16 and the journal 15 . The cleavage groove 17 is designed in such a way that it is broken by the deformation 11 , so that the locking part 10 can be rotated about the axis of rotation 13 and brought into its active position.

In the illustrations of FIGS. 1 and 2 , the locking element 10 is configured in the form of a rod. The bearing axis 13 extends through the closure part 10 , that is to say between its longitudinal ends, so that the closure part 10 behaves in the manner of a balancing lever with respect to its degree of freedom.

In order to switch to the active position, the component part 12—with which the locking part 10 cooperates in the case of deformation 11 of the door 4—in the embodiment shown is a lever 19, which is mounted on a On the side impact bearing 20, or molded on the side impact bearing. In this case, said side impact bearing 20 is arranged inside the vehicle door 4 . Alternatively, the component part 12 can also be formed by the outer surface 5 or by a lever arranged on the outer surface 5 . Furthermore, a linear movement is also conceivable instead of a rotation of the locking part 10 , whereby the corresponding locking part 10 can also basically be arranged directly on the outer surface 5 or directly on the side impact bearing 20 .

On the entry side, the unlocking device 6 has a rotatably mounted actuating lever 21 . The joystick 21 is connected with the hand handle 3 by, for example, a driving lever 22 on the one hand, and on the other hand, especially through a cable that is installed in the soft sleeve steel cable 7 and is firmly connected with the drag cable 9, not shown here. The connecting part is connected with a soft casing wire rope 7. Actuation of the handle 3 via the lever 22 causes a rotation of the joystick 21 , on which the joystick actuates the soft sheath cable 7 , whereby the door lock is finally unlocked by actuating the handle 3 . According to a particularly advantageous embodiment, the actuation lever 21 is designed as an inertial locking mechanism. In the event of an outwardly directed acceleration force, for example indicated by an outwardly directed arrow 23 in FIG. 1 , the inertial locking mechanism 21 blocks an opening or unlocking operation of the door lock. For example, the handle 3 introduces a torque into the inertial locking mechanism 21 through the lever 22 based on the outward acceleration force 23 . However, the inertia locking mechanism 21 generates a counter torque in the opposite direction based on the outward force 23 , and the counter torque acts on the handle 3 through the lever 22 . By advantageously adjusting the masses and lever forces of the handle 3 and the inertial locking mechanism 21 , it is possible for the handle 3 to be held in its locked position by the inertial locking mechanism 21 in the event of outwardly directed acceleration forces. This prevents the door lock from being actuated.

Now, according to a preferred embodiment, the locking part 10 engages in the travel of a part of the unlocking device 6 during a crash, ie in its active position, whereby the displaceability of the corresponding part is prevented. In this case, one part that is moved at the time of unlocking operation of the door lock is employed. In this embodiment, a joystick 21 or an inertial locking mechanism 21 is used. The operating part 10 rotated to its active position stops the operating lever 21 or the inertial locking mechanism 21 in its rest position, and thereby hinders the rotational movement of the operating lever 21. The operating lever must have a soft casing wire rope 7 to pass through, so as to A soft casing wire rope 7 can be manipulated. Alternatively, the locking part 10 can also be arranged or arranged in such a way that it engages in the unlocking device 6 in another position. Likewise, the locking element 10 can also be arranged or arranged in such a way that, for example, it blocks or limits the rotational movement of the handle 3 .

According to a particularly advantageous embodiment, the closure part 10 can be provided for its part with a cleavage groove 24 , which is also identified in FIGS. Shows. This cleavage groove 24 of the locking part 10 is necessary when the locking part 10 is displaced and held in its active position due to a collision, thereby permanently restricting the unlocking operation of the door lock. On the one hand, the cleavage groove 24 is dimensioned in such a way that it absolutely withstands the door opening force applied to the handle 3 during a collision, so that despite the presence of the cleavage groove 24 , the locking element 10 can still perform a locking function. On the other hand, however, the cleavage groove 24 of the locking part 10 is designed in such a way that a stronger, especially sufficiently large force of the manual actuation handle 3 that acts in an emergency can be transmitted to the locking part 10, which force The closure element 10 is destroyed at the cleavage groove 24 . This destruction of the locking component 10 on the cracking groove 24 eliminates the restriction on the unlocking device 6 , so that it is feasible to open the door lock again by pulling the handle 3 . This is especially important when the vehicle occupants may no longer be able to open the doors themselves from the inside as a result of a crash.
