Description

An automobile door handle

The invention relates to a motor vehicle door handle for Türschloss- and / or door operation of a motor vehicle, with a handle housing and arranged in the handle housing pull handle, wherein the pull handle is flush in a closed position with the handle housing and / or rests in the handle housing and is displaced into an operating position in which the pull handle protrudes from the handle housing to the outside and is engaged behind, wherein the manual lock on the pull handle in the operating position, the door lock and / or the door opens.

Such door handles, which have a pull handle, which is flush in its rest or closed position with the body of the motor vehicle or the handle housing, are known for example from DE 100 15 887 C1 and DE 10 2004 036 663 A1.

From these documents door handles for a motor vehicle with a handle housing and a pivotally mounted in the handle housing pull handle is known, which is flush in a closed and rest position with the body of a motor vehicle or a handle housing, the pull handle in a swung out, protruding from the body Operating position can be moved, in which the pull handle is engaged behind and which opens the door lock and / or the door when pulling on the pull handle.

CONFIRMATION COPY A disadvantage of the known motor vehicle door handles is that they have very complex constructions to make it possible to move the pull handle from its rest and closed position to its operating position. The invention is therefore the object of developing a generic motor vehicle door handle for Türschloss- and / or door operation of a motor vehicle such that it is displaceable by means of a simplified mechanically stable mechanism from its closed position to its operating position.

This object is achieved by a motor vehicle door handle according to claim 1. Advantageous developments of the invention are specified in the subclaims. Particularly advantageous in the motor vehicle door handle for Türschloss- and / or door operation of a motor vehicle, with a handle housing and arranged in the handle housing pull handle, wherein the pull handle is flush in a closed position with the handle housing and / or rests in the handle housing and is displaced into an operating position in which the pull handle protrudes from the handle housing to the outside and is engageable behind, wherein when pulling manually on the pull handle in the operating position, the door lock and / or the door opens, it is that the pull handle spaced from each other has two pivot points, wherein the pull handle the first articulation point articulated at one end of a first rotary lever and spaced therefrom is articulated to the second articulation point at one end of a second rotary lever, wherein the two rotary levers rotate about axes of rotation to move the pull handle from the closed position to the operative position.

Characterized in that the pull handle is arranged via two spaced-apart pivot points on two rotary levers, which rotate around again spaced apart rotational axes, a robust and simple kinematics is provided, which is the displacement of the pull handle from the closed position, in which the pull handle flush with the handle housing terminates or springs back into the handle housing, realized in the operating position, in which the pull handle is shifted outwards and can be engaged behind. The invention thus advantageously makes it possible to shift the pull handle from a closed and inoperative position to its operating position. In this case, the axes of rotation about which rotate the rotary lever during displacement of the pull handle, at a distance from each other to run parallel or skewed to each other or intersect at a point outside of the handle housing. The terms rest position and closed position are used interchangeably in the context of the invention and describe the position in which the pull handle is flush with the handle housing or recessed in the handle housing springs back preferably are the pivot points in the extension of the pull handle behind the other. With the extension direction while the direction from the handle housing is meant to the outside, ie the direction corresponding to the main movement direction of the pull handle from the closed position to the operating position. Preferably, the axes of rotation about which rotate the rotary lever when moving the pull handle, also in the extension direction of the pull handle behind the other.

The distance between the two articulation points of the pull handle and the distance between the axes of rotation of the two rotary levers can be the same, so that the articulation points and the axes of rotation of the two rotary levers form corner points of a parallelogram. This means that in the pivoting of the rotary lever, the two connecting lines between articulation point and pivot point of the first rotary lever with the connecting line of the second pivot point with the axis of rotation of the second rotary lever are parallel and thus span a parallelogram. However, this is not necessarily the case. Alternatively, the distance between the articulation points can deviate from the distance between the axes of rotation of the rotary levers, so that a trapezoid is clamped. Advantageously, however, each resulting kinematics which results in that the pull handle from its closed position within the handle housing is displaced into its operating position, wherein the fact that the pull handle via two spaced pivot points on two rotary levers, which in turn are pivotable about spaced axes of rotation is articulated, is moved out on an arcuate path from the handle housing, without the inclination of the pull handle relative to the handle housing changed significantly, because it is undesirable, in particular for aesthetic reasons that the pull handle is swung out on a circular path from the handle housing in its operating position and thereby significantly changes its inclination relative to the handle housing.

The invention thus provides a simple and robust mechanism which allows the desired movement of the pull handle from its closed position to its operative position and back.

The motor vehicle door handle preferably has an actuating lever which acts on at least one of the two rotary levers and pivots it about its axis of rotation, thereby causing the pulling handle to be shifted from the closed position into the operating position.

Particularly preferably, the motor vehicle door handle has an electromotive drive which engages directly or indirectly on at least one of the two rotary levers and pivots this about its axis of rotation and thereby causes the displacement of the pull handle from the closed position into the operating position.

Particularly preferably, this electromotive drive is triggered by the fact that an access code is exchanged on the part of a locking device of the motor vehicle via a radio link with an external identification transmitter and automatically actuated upon detection of access authorization of the electric motor drive to extend the pull handle from its closed position to the operating position. Preferably, the motor vehicle door handle has a locking element, which is directly or kinematically coupled to the pull handle and in the closed position of the pull handle engages and locks the pull handle, wherein the locking element is displaced by means of an actuating lever in a release position before the operating lever on at least one the two rotary lever attacks and this pivots about its axis of rotation.

The actuating lever, which acts on at least one of the two rotary levers, can accordingly be developed in such a way that the actuating lever in its pivoting movement before it acts on at least one of the two rotary levers, first displaces a locking element located in the closed position of the pull handle into a release position, so that the pull handle is in turn unlocked and is displaceable in its operating position.

This locking element, which is engaged and the pull handle locked in its closed position, serves as accident protection to avoid that the pull handle is displaced due to the inertia in the event of an impact of the motor vehicle due to the inertia from the closed position into the operating position to ensure that in the event of an accident, the vehicle door does not open, so that the protection for the vehicle occupants is maintained.

The blocking element can be formed by a cam, which is arranged at a front end of a coupling lever coupled to the actuating lever and which is movable in a link on the handle housing from a detent position to a release position.

This cam forming the blocking element is kinematically coupled to the pull handle and thus locks the pull handle in its pivotal position when the cam is in its rest position within the gate on the handle housing. After moving out of the cam from the detent position turn the pull handle can be moved from its closed position to the operating position, since the locking member forming cam in the slide guide of the handle housing is movable. As a result, a relative movement of the pull handle relative to the handle housing is made possible.

In a preferred embodiment, the motor vehicle door handle has at least one spring element which exerts a spring force acting in the direction of the closed position on at least one of the two rotary levers.

Accordingly, this spring element causes when switching off or removing a drive in the direction of the operating position, an automatic displacement of the pull handle back into the closed position in the handle housing. The spring element can be a helical spring, a plate spring, a torsion bar spring, a spiral spring or the like. The spring action in the closing direction can thus be generated by exerting on one of the rotary levers a force with a point of application at a distance from the axis of rotation which has a component in the opposite direction to the direction of extension. Alternatively or cumulatively, a torque at the axis of rotation may also be applied to at least one of the rotary levers in the closing direction, i. be applied against the extension direction.

Preferably, the motor vehicle door handle has an actuating element which acts indirectly or directly on at least one of the two rotary levers and pivots this on a manual actuation of the actuating element about its axis of rotation and moves the pull handle into the operating position. By such a manually operable actuator, it is possible to move the pull handle from its closed position within the handle housing in its operating position outside of the handle housing, even at a failure of an electric motor drive or the like at least manually operable swinging the pull handle from his To allow closed position in the operating position and thereby allow the operation of the door lock and the vehicle door.

An embodiment of the invention is illustrated in the figures and will be explained in more detail below. Show it:

Figures 1 - 5 a side view of a motor vehicle door handle with different positions of the pull handle relative to the handle housing;

Figures 6 - 10 is a rear view of the motor vehicle door handle according to the

Figures 1-5 in different positions of the pull handle relative to the handle housing analogous to Figures 1-5. In Figures 1-10 identical components are provided with identical reference numerals. Figures 1 - 5 show side views of a motor vehicle door handle in different positions of the pull handle 2 and the pull handle 2 from the closed position of Figure 1 in the operating position according to Figure 5 kinematics displacing. The continuous movement of the pull handle 2 relative to the handle housing 1 show the figures in a corresponding order of their ascending numbering.

Figures 6 - 10 show the rear views of the motor vehicle door handle in different positions of the pull handle 2 and the pull handle 2 from the closed position of Figure 6 in the operating position of Figure 10 relocating kinematics, the individual positions shown in Figures 6-10 the various positions according to Figures 1-5 correspond and thus show the displacement of the pull handle 2 from the closed position to the operating position.

Within the handle housing 1 of the pull handle 2 of the motor vehicle door handle is arranged, wherein the pull handle 2 in the closed position shown in Figure 1 and Figure 6 is flush with the handle housing 1. The pull handle 2 is coupled via a first pivot point 21 to the upper end of the first rotary lever 10. The first rotary lever 10 is pivotally mounted about its axis of rotation 1. The axis of rotation 1 is stationary relative to the housing 1.

Further, the pull handle 2 via the second pivot point 22 to the upper end of the second rotary lever 20 is pivotally connected. The second rotary lever 20 is pivotally mounted about the axis of rotation 12. The axis of rotation 12 is also stationary relative to the housing 1.

The arrow 3 according to FIG. 1 characterizes the extension direction of the pull handle 2 with respect to the handle housing 1.

The two pivot points 21, 22, by means of which the pull handle 2 is hinged to the two rotary levers 10, 20, are spaced apart in the extension direction 3 from each other. The two axes of rotation 11, 12 of the two rotary levers 10, 20 are also in the extension direction 3 in a row.

In the image plane according to Figures 1 to 5 in front of the second rotary lever 20 is disposed an actuating lever 30 which is also rotatably mounted on the second axis of rotation 12.

In the illustrations according to FIGS. 6 to 10, this actuating lever 30 is located to the left of the second rotary lever 20 and, like the second rotary lever 20, is rotatably mounted on the second axis of rotation 12.

To displace the pull handle 2 from the closed position shown in Figure 1 and Figure 6 within the handle housing 1 in the operating position shown in Figure 5 and Figure 0, in which the pull handle 2 is pushed out of the handle housing 1, engages over a projection 32 at the actuating lever 30, an electric motor drive with a force component in the direction of the arrow 4, which runs parallel to the extension direction 3 of the pull handle 2 at. The displacement of the pull handle 2 via the actuating lever will be apparent from the figures 1 to 5 or analogously with reference to the figures 6 to 10.

At the upper end of the actuating lever 30, a pivot lever 40 is coupled via an eye 31 to the actuating lever. The actuating lever 40 has a slot 41, by means of which the actuating lever slides over the axis passing through the second pivot point 22 axis away, so that a relative movement of the upper end of the pivot lever 40 relative to the pivot point 22 is possible. At the upper end of the pivot lever 40 acting as a locking element cam 42 is arranged, which is in the closed position shown in Figure 1 and Figure 6 in its locking position. The detent position of the cam 42 is characterized in that the cam prevents relative movement of the pull handle 2 relative to the housing 1 in this position. This is achieved in that the cam 42 is retracted within the arranged on the housing 1 slotted guide 13 in the locking position 14, wherein this locking position 14 by the flanks right and left of the slide guide 13 hold the cam and prevent movement of the pull handle 2 in the extension 3 , This locking position is formed by a pocket-shaped receptacle 14 of the slotted guide 13, in which the cam goes. Due to the right and left flanks of the pocket-shaped receptacle 14, a relative movement of the pull handle 2 with respect to the handle housing 1 is not possible, as long as the cam 42 is within the detent position 14.

This cam 42, which is engaged in the closed position of the pull handle 2 and the pull handle 2 locked in its closed position, serves as accident protection to avoid that the pull handle 2 due to a pulse in the event of an impact of the motor vehicle due to the inertia of the Closed position is shifted out into the operating position. This ensures that even in the case of a strong pulse due to an accident, the vehicle door does not open, so that the protection for the vehicle occupants is maintained.

Upon actuation of the pivot lever 30 via the electric motor drive in the direction of arrow 4, the pivot lever 30 about the axis of rotation 12 around the image plane according to Figures 1 to 5 pivoted to the left and causes via the coupling with the pivot lever 40 via the eye 31, a displacement of the upper end of the pivot lever along the slot 41, whereby the cam 42 from the detent position 14 within the slide guide 13 out is shifted above, as shown in Figure 2 and correspondingly in Figure 7. After the cam 42 has been displaced out of the detent position 14 within the slotted guide 13, it is possible to displace the pull handle 2 with respect to the housing 1 in the extension direction, since the slotted guide 3 is part of the stationary housing 1. This release position, in which the cam 42 has left the locking position 14, is shown in Figure 2 and Figure 7.

Furthermore, the actuating lever 30 has a cam 33 which extends within a slot 25 in the second rotary lever 20. In this case, the slot 25 is dimensioned within the second rotary lever 20 such that the actuating lever 30 against the second rotary lever 20 is free to pivot as far as the effective locking element cam 42 from the locking position 14 of Figure 1 and Figure 6 in the release position shown in FIG 2 and Figure 7 is extended. In the torque shown in FIG. 2 or FIG. 7, the cam 33 of the actuating lever 30 comes to rest within the oblong hole 25 of the second rotary lever 20, so that further pivoting of the actuating lever 30 about the second axis of rotation 12 to the left in the image plane according to FIGS 1-5 thereafter causing the second rotary lever 20 to rotate about the second pivot 12 counterclockwise as well.

Due to the kinematic coupling of the second rotary lever 20 via the second articulation point 22 with the pull handle 2, as a result of a further actuation of the actuating lever 30, the pull handle 2 in the extension direction 3 out of the closed position within the housing 1 out in the image plane according to the figures. 1 shifted to the left to 5, as shown in Figures 3 and 4. In this case, the cam acting as a blocking element 42 slides along the slotted guide 13 and allows a displacement of the pull handle 2 in the extension direction 3 to its in Figure 5 or Figure 10 illustrated operating position in which the cam 42 comes to the end of the slide guide 13 to the stop and the pull handle 2 is displaced in its operating position outside of the housing 1. In the operating position of the pull handle 2 according to Figure 5 or Figure 10, the pull handle is engaged behind, so that unlocked by a manual pull on the pull handle the door lock and the door of the motor vehicle can be opened.

A return movement of the pull handle 2 from the operating position according to FIG. 5 or FIG. 10 back to the closed position or closed position within the housing 1 according to FIG. 1 or FIG. 6 again takes place exactly the other way round and can be reproduced in descending order of their numbering.

In this case, the cam 42 slides along the slotted guide 13 in the image plane according to the figures 1 to 5 to the right, while the rotary levers 10, 20 rotate about their respective axis of rotation 11, 12 in the clockwise direction.

After the pull handle 2 has reached its closed position according to FIG. 2 or FIG. 7, the actuating lever 30 is further rotated in the clockwise direction in order to reach the position according to FIG. 1 or FIG. 6 and to retract the cam 42 into the latching position 14. If the position of the arrangement according to FIG. 1 or FIG. 6 is reached again, the pull handle 2 is engaged by the engagement of the cam

42 locked in the pocket-shaped receptacle 14.
