Description

Device for actuating a movable part of a

motor vehicle

The invention relates to a device for actuating a movable part of a motor vehicle, in particular a door or tailgate or the like, with a carrier which is fastened to the inside of the movable part, a pivotable about a first axis rocker element, a handle member having a first and a second handle end, wherein the second handle end is connected to the swing member, whereby the handle member is pivotally movable together with the swing member to the carrier, and a support provided on the second axis, on which the first handle end is rotatably mounted.

DE 102 17 488 B4 describes a device with a carrier which can be fastened in the area of the door outer panel from the inside of the door of the motor vehicle. The carrier has a bearing pin for a bearing support on, which is located in a swing element. Further, a grip element is provided, which is coupled with its first and second handle end with the pivotable about an axis rocker element. Here, the swinging element is designed as a over the entire length of the handle member extending component. It has been shown that in some applications of such a device, a slight tilting mobility of the handle element can adjust, which can be perceived haptically by the user adversely.

It is an object of the present invention to provide a device of the type mentioned, in which the disadvantages mentioned are avoided, in particular a device is provided in which the tilting mobility of the handle can be reduced.

To solve this problem, a device having the features of claim 1 is proposed. In the dependent claims preferred developments are carried out.

For this purpose, the invention provides that the rocker element is designed with a space spaced from the first axis receiving area having a third axis at which the second end of the handle is rotatably coupled to the rocker element, whereby a tilting mobility of the handle element is prevented.

According to the invention, a device is provided in which the grip element is arranged without play on the movable part of the motor vehicle. This is achieved, inter alia, that two axes are provided on the rocker element. Appropriately, in this case, the first axis is positioned on the carrier. On the other hand, the third axis serves to ensure rotational mobility of the second handle end during actuation of the handle element by the user. At the same time, it has been found that the tilting mobility of the grip element can be almost prevented by this inventive articulated construction on the swing element. By a wide receiving area for the third axis, a high rigidity of the handle element can be additionally achieved. Advantageously, the handle element is pivotable with the swinging element from a first position to a second position and vice versa, wherein the handle element is mounted on the second and the third axis such that the handle element from the first position to the second position performs a sine-shaped movement wherein at the same time the first handle end rotates about the second axis. The first position is the rest position of the handle element. In the second position, in which the grip element is pivoted out of the movable part, an activation of a closure for opening the movable part is triggered. In the case of the sinusoidal movement, a wave-like movement of the grip element is to be understood here. As the handle member moves from the first position to the second position, the handle member moves both out of the moving part toward the user and almost parallel to the moving part. In a preferred embodiment of the invention, the gripping element is designed with a first contacting region facing the first gripping end and a second contacting region spaced from the first contacting region and facing the second gripping end. At the same time, the first and the second contacting region in the first position of the grip element are each in contact with a seal. This sinusoidal movement is advantageous, inter alia, for the reason that during the movement of the grip element from the first to the second position, the first and the second contacting region simultaneously disengage from the seals, whereby the susceptibility of the seal to wear can be considerably reduced.

In one possible embodiment of the invention, the second end of the handle is rotatably mounted directly on the receiving area. Advantageously, the second end of the handle is connected via a rotatable fixed bearing on the receiving area with the rocker element.

In a further alternative embodiment, a coupling element is provided, which is arranged rotatably in the receiving region on the third axis, wherein the coupling element is designed with a receiving means, which serves for fastening of the second handle end. During the movement of the handle element, the coupling element pivots about the third axis, wherein at the same time the second end of the handle is rigidly connected to the coupling element.

It is particularly advantageous that the first end of the handle is open on one side as an elongated hole, wherein the first end of the handle comprises the second axis at least partially. About the slot receives the first end of the handle - in addition to its pivoting movement about the second axis - another degree of freedom for movement of the handle element almost parallel to the movable part to ensure a wave-like movement of the handle element.

According to the invention, the first and the second axis can be connected via a notional orientation line, wherein the third axis is arranged at a distance from the orientation line. In a preferred embodiment of the invention, in the first position of the handle element, the third axis is positioned on a first side at a distance from the orientation line. Here, the third axis approaches the orientation line, while the handle member moves from the first to the second position. In an intermediate position, the grip element reaches the orientation line, wherein in the further movement of the grip element, the third axis reaches a second side, on which the second position of the grip element is achieved. The second page is separated from the first page by the orientation line. During the movement of the third axis on the first side to the orientation line, the first handle end performs a first lifting movement. In addition to a rotation of the grip element about the second axis, the first handle end or the grip element executes the first stroke, which takes place almost parallel to the movable part. This means that the lifting movement takes place along the extension of the grip element. During the movement of the third axis on the second side from the orientation line to the second position of the grip element, the first grip end or the grip element executes a second stroke movement, which is directed counter to the first stroke movement.

In an alternative of the invention, it is also conceivable that during the movement of the handle element from the first to the second position, the third axis moves relative to the orientation line, without reaching the orientation line, in particular to cut, whereby the first end of the handle performs only one stroke in one direction. Again, there is a sinusoidal movement of the handle member, wherein the sinusoidal movement is shortened in contrast to the aforementioned embodiment.

It is also possible that in the first position of the handle element, the third axis is located on the orientation line. During the movement of the grip element in the direction of the second position, the third axis of the orientation line, whereby likewise the first grip end only performs a stroke movement in one direction, moves away.

Preferably, the angle of rotation which the third axis moves during the movement of the grip element from the first to the second position to the first axis is less than 90 °, preferably less than 45 ° and particularly preferably less than 30 °. As a result, a particularly compact construction of the swing element is achieved within the carrier.

Furthermore, it can be provided that the device according to the invention is monitored by control electronics. For safety reasons, it may be advantageous if in addition to the detection of the position of the rocker element and the positions of the handle element or the coupling element are detected. This can be done, for example, via sensors, in particular magnetic field sensors, which detect the magnetic field of a permanent magnet attached to the coupling element, to the rocking element or to the grip element.

Further advantages, features and details of the invention will become apparent from the following description in which, with reference to the drawings, an embodiment of the invention is described in detail. The features mentioned in the claims and in the description may each be essential to the invention individually or in any desired combination.

In the following description, a possible embodiment of the device 10 according to the invention for actuating or opening a door 12 of a motor vehicle is shown. In this case, the device 10 has a carrier 11, which is fastened to the inside of the door 12. Further, a swing member 20 is disposed on the carrier 1 1 about a first axis 13. In the outer area, which is accessible to the user, a handle member 40 is provided, which from a first position (rest position), which is illustrated in Figure 1 a, via an intermediate position, which is shown in Figure 1 b, in a second position according to Figure 1 c is movable.

The grip element 40 according to the present invention has a first 41 and a second grip end 42. The first handle end 41 is on a second axis 14, which the carrier 1 1 is formed, rotatably mounted. The second handle end 42 is connected via a rotatable fixed bearing with the rocker element 20 in operative connection. While the handle member 40 is pivoted to the second position, simultaneously moves the swing member 20 about the first axis 13 with. In the present embodiment, the second handle end 42 via a coupling element 16, which is illustrated in an enlarged view in Figure 2b and 3, indirectly connected. The swinging element 20 is in this case designed with a spaced-apart from the first axis 13 receiving area 21 in which the third axis 15 extends. The coupling element 16 has at its two end regions in each case a cylindrical bearing element 16b which is rotatably mounted in the respective two receiving regions 21 of the rocking element 20 about the third axis 15.

The coupling element 16 is formed with an opening 16a, in which the second handle end 42 is held reliably, which is particularly illustrated in FIG. During assembly of the device 10 according to the invention, the carrier 1 1 is fastened to the inner side of the unit comprising the swinging element 20 and the coupling element 16. Subsequently, the handle member 40 is fixed from the outside, wherein the second handle end 42 is pushed through the slot-shaped opening 16a. As FIG. 2 b illustrates, the coupling element 16 has a first bore 19. The second handle end 42, which is adapted in its contour to the geometry of the opening 16a, also has a second bore (not shown here), wherein in the mounted state of the handle member 40, a screw 22 through the first bore 19 and through the second bore of second handle end 42 extends and at the same time extends through the opening 16a. Thus, a reliable attachment of the second handle end 42 is achieved on the coupling element 16.

Furthermore, the device 10 according to the invention has a spring element 23, which is in operative connection with the swinging element 20. The spring element 23 exerts in the second position of the grip element 40 such a restoring force that the swing element 20 moves independently in the position shown in Figure 1 a. In the present embodiment, the swing member 20 has two pins 24 which are spaced from each other, wherein the spring element 23 on the pin 24th is plugged. The pins 24 are located on the first axis 13. The spring element 23, which is designed as a spiral spring, in this case bears against a contact surface formed on the rocker element 20.

While the handle member 40 is moved according to Figures 1 a to 1 c, the handle member 40 performs a sine-shaped movement. This means that from the first position to the intermediate position, the grip element 40 first executes a movement obliquely right downwards according to FIG. 1 a, which is indicated by the arrow illustration shown schematically. First, the first handle end 41 rotates clockwise about the second axis 14. At the same time performs the first handle end 41 and the handle member 40 is a lifting movement to the right. The lifting movement is substantially parallel to the door 12 or opposite to the direction of travel of the motor vehicle. The gap between the grip element 40 and the bearing shell 18 adjacent thereto, which is fixedly arranged on the door 12, becomes smaller starting from FIG. 1 a to FIG. 1 b. In order to realize the said lifting movement in the present invention, the first handle end 41 is open on one side as an elongated hole, wherein the slot comprises the second axis 14 at least partially. The distance x between the second axis 14 and the first grip end 41 increases during the movement of the grip element 40 from the first position to the intermediate position. During the movement of the grip element 40 from the intermediate position according to FIG. 1 b to the second position according to FIG. 1 c, the grip element 40 moves obliquely left downwards. This means that the grip element 40, on the one hand, continues to rotate about the second axis 14, furthermore a lifting movement of the grip element 40 takes place to the left parallel to the door 12 or in the vehicle direction. The distance x in the region of the first handle end 41, starting from FIG. 1 b, becomes smaller up to the state in FIG. 1 c.

The sinusoidal or wave-like reciprocating movement of the grip element 40 according to FIGS. 1 a to 1 c is achieved via the articulated construction on the swinging element 20 as well as by the inventive mounting of the first 41 and the second grip end 42. In the first position of the grip element 40 (FIG. 1 a), the third axis 15 is positioned on a first side 31 at a distance from a notional orientation line 17 connecting the first 13 and the second axis 14. During the movement The handle element 40 from the first position to the second position according to FIG. 1 c initially approaches the third axis 15 of the orientation line 17. In the intermediate position according to FIG. 1 b, the third axis 15 lies on the orientation line 17. During the movement of the third axis 15 on the first side 31 to the orientation line 17 performs the first end of the handle 41 - in addition to the rotation about the second axis 14 - the first lifting movement to the right. In a further movement of the grip element 40 in the direction of the second position according to Figure 1 c, the third axis 15 of the orientation line 17 moves away, so that the second lifting movement is initiated, which is directed against the first stroke. One of the advantages of this sine-shaped movement of the handle member 40 is that the seal 27 against which the handle member 40 abuts in its first position with its first and second contacting portions 26a, 26b becomes less worn. It has advantageously been found that, during the movement of the grip element 40, the first 26a and the second contacting region 26b disengage from the seal 27 simultaneously with their entire surface, starting from the first position.

In a further, not dargstellten embodiment alternative, it is of course possible that the handle member 40 performs a lifting movement only in one direction, starting from the first position to the second position. This can be realized inter alia, that during the movement of the handle member 40 from the first to the second position, the third axis 15 moves relative to the orientation line 17 without the orientation line 17 to reach or cut.

Another advantage of this embodiment is that the tilting mobility of the handle member 40 due to the special storage on the third axis 15 of the first axis 13 rotatably mounted rocker element 20 is realized. The rigidity of the grip element 40 is additionally achieved by the wide mounting of the bearing elements 16b in the receiving regions 21 of the swing element 20. This storage has a width that exceeds the width B of the handle 40, which is indicated in Figure 4. Furthermore, the carrier 11 has an aperture 30 in which a lock cylinder (not shown) is inserted into the carrier 11 and there can be attached. The rocker element 20 is relatively small and compact rotatably mounted within the carrier 1 1 and is connected only at two areas with components of the device 10, namely on the first axis 13 and on the third axis 15. At the third axis 15th opposite side, the rocker element 20 has at least one mass balance weight 25 which moves during the movement of the rocker element 20 about the first axis 13. This mass balance weight 25 serves to ensure that the swing element 20 is not unintentionally pivoted in the event of a side impact due to the centrifugal forces that occur, as a result of which an undesired opening operation of the door 12 would be triggered. In this case, the mass balance weight 25 counteracts the acting centrifugal forces, so that a movement of the swing element 20 about the first axis 13 is excluded.

The present device 10 is in operative connection with a closure, not explicitly shown, of the motor vehicle door 12. Upon movement of the handle member 40 from its first position to its second position, the shutter is actuated via an outlet, not shown. The outlet may be, for example, a Bowden cable which may be attached to the swinging element 20 or to the grip element 40, in particular to the second grip end 42.
