Description

The invention relates to a motor vehicle door, in particular a handleless motor vehicle side door, with a door leaf, furthermore with a locking member articulated to a motor vehicle body for fixing the door leaf in predetermined angular positions compared to the motor vehicle body, and with at least one actuator working on the door leaf , which causes at least a gap opening of the door leaf relative to the motor vehicle body.

Motor vehicle doors are consistently equipped with locking members for fixing the door leaf in predetermined angular positions in comparison with the motor vehicle body. For this purpose, the locking member is articulated to the motor vehicle body, usually in such a way that its pivot point lies outside the pivot axis of the door leaf, which is predetermined by the hinge axes. The locking member generally protrudes into the interior of the door leaf via an opening on a side edge. Due to its articulation on the motor vehicle body, which is eccentric with respect to the hinge axes, the locking member carries out extension and retraction movements relative to the door leaf when the door leaf is moved.

Such locking members usually have a locking arm or locking arm with several locking recesses. Locking elements attached to the door leaf can dip into the locking recesses. In this way, the predetermined angular positions of the door leaf can be realized in comparison to the motor vehicle body. Such a procedure is well known, for which purpose only refer to the DE 41 30 782 A1 referenced.

In particular in the case of handleless motor vehicle side doors, in order to open the motor vehicle side door in question, it is necessary to open this or the associated door leaf at least in gaps. This generally means opening gaps in the range from 100 mm to 200 mm compared to the motor vehicle body. This allows an operator to reach into the gap behind the door leaf and open it completely. The at least one actuator working on the door leaf ensures that the door leaf is opened at least in a gap with respect to the motor vehicle body.

In the generic prior art according to DE 10 2013 202 801 A1 a device for actuating a motor vehicle door with a locking function is described. The device has an actuator which can be fastened to the motor vehicle door and a pivot lever which can be pivoted about an actuator axis by the actuator. In addition, an actuating arm or a locking member is provided for fixing the motor vehicle door in predetermined angular positions compared to the motor vehicle body. In the known teaching, the procedure is such that the actuating arm or the locking member is rotatably coupled to the pivot lever that can be acted upon by the actuator. From the US 2009/0051192 A1 a motor vehicle door is known and an actuator which is connected to a fixing element articulated to the vehicle body for fixing the door leaf and which drives it.

This is intended to open up the possibility of optionally retrofitting conventional devices or the devices described with as little effort as possible. As a consequence of this, a kinematically relatively complex design is realized because the actuator works on the swivel lever which is pivotable about the actuator axis and which in turn is rotatably coupled to the actuating arm or locking member. This is where the invention comes in.

The invention is based on the technical problem of further developing a motor vehicle door in such a way that, in a structurally simple manner, the door leaf is opened at least in a gap with respect to the motor vehicle body.

To solve this technical problem, a generic motor vehicle door and, in particular, a handleless motor vehicle side door. Within the scope of the invention, a door leaf, furthermore a locking member hinged to a motor vehicle body for fixing the door leaf in predetermined angular positions compared to the motor vehicle body, and one on the Door leaf working actuator, which causes at least one column-wise opening of the door leaf with respect to the motor vehicle body, the actuator working on the door leaf is connected to the fixed part member and drives this directly to adjust the door leaf, the fixing member having a counterstop acting on a door leaf-side stop and has a latching arm for interaction with locking elements on the door leaf, and a drive for the door leaf is provided in addition to the actuator, the drive being connected to the counter flange via the stop on the door leaf g is working on the locking member.

In the context of the invention, the actuator works to open the door leaf at least in a gap, ie directly or directly on the locking member. That helps, some intermediate elements, as they are the generic prior art according to the DE 10 2013 202 801 A1 In the form of the swivel lever, mandatory calls are avoided. This initially reduces the design effort. In addition, the invention is based on the knowledge that the actuator connected to the locking member drives it directly and to the extent that it is able to adjust the door leaf so that at least the opening of the door leaf is achieved. That helps, the adjusting movements of the Feststellgiledes effected with the help of the actuator are consistently sufficient to open the door leaf at least in gaps, so that a bedlener can reach into the gap and reach behind the door leaf to open it completely.

Of course, it is also within the scope of the invention if the actuator connected to the locking member starts this directly to adjust the door leaf and not only ensures that the door leaf is opened by a gap, but also in principle completely opens the door leaf and can close if necessary. The locking element itself may transfer this adjusting movement caused by the actuator to the door leaf via the locking elements mentioned above. In fact, the movement of the locking member initiated with the aid of the actuator corresponds to the fact that it is "lengthened", as it were, or the distance between one end of the fixed member and the joint for connecting the locking member to the motor vehicle diamond is increased at the other end. As a result, the door leaf is issued for the opening at least in a gap. The general procedure here is that the actuator ensures that the door leaf is opened in a gap with respect to the motor vehicle body. In contrast, the drive then effects a complete opening / closing of the door leaf with respect to the motor vehicle body, that is, the drive works basically independently of the actuator, so the drive can open the door leaf completely or close the door leaf completely. Likewise, both complete openings and closings of the door leaf with respect to the motor vehicle body are possible with the aid of the drive and are included according to the invention.

According to the invention, the locking member has a counterstop acting on a door-leaf-side stop and a latching arm for interacting with locking members on the door leaf. In addition, the locking member advantageously has an adjusting rod.

In fact, the actuator is mostly designed as a linear control element. The procedure here is that the control rod of the locking element is acted upon by an adjusting nut connected to the actuator for linear adjustment. The actuator ensures that the adjusting nut rotates. As a result, the adjusting rod immersed in the adjusting nut performs corresponding linear movements, the same applies to the locking member in the Whole. These linear movements of the fixed actuator are transferred to the door leaf to open it via the door-winged stop.

According to the invention, the drive works via the stop on the door leaf on the locking member. In fact, the procedure here is that the drive interacts with the counter-stop on the locking member via the stop on the door leaf. For this purpose, the stop on the door leaf is advantageously designed to be adjustable.

In fact, the stop in question can be two drive disks which can be moved relative to one another. The two drive pulleys may also be coupled to one another via springs.

A drive pulley is usually designed as a first drive pulley interacting with the locking member. In contrast, the other drive pulley is a second drive pulley connected to the drive. Since the two drive disks are coupled to one another by spring force and, moreover, are designed to be movable relative to one another, there is also a decoupling of the actuator on the one hand and the drive on the other hand. Because due to the relative mobility of the two drive disks to one another and consequently the adjustable or flexible design of the stop on the door leaf, the actuator and the drive do not rigidly attack the stop, but rather are decoupled from one another and movable to one another.

In this way, any play when moving the drive can be compensated for, as can play when the actuator is operated. As a result, the drive and the actuator can be operated independently of one another and used according to the invention for the desired movement of the door leaf. All of this succeeds in a structurally strikingly simple manner and accordingly inexpensive and functionally reliable. In addition, the locking element is equipped with a further functionality because it moves with the help of the actuator and is used to adjust the door leaf. This is where the main advantages can be seen.

a detail from the Fig. 4 shown in perspective.

The figures show a motor vehicle door, the door leaf 1 of which is pivoted to a motor vehicle body 2 via one or more hinges 3. The hinges 3 or their hinge axes define a pivot axis of the door leaf 1. The motor vehicle door shown is not restrictively a motor vehicle side door. In addition, the motor vehicle side door is designed without a handle, so it does not have a door handle or a comparable handle for opening or closing. For this reason, the motor vehicle door in question must be opened at least in a gap with respect to the motor vehicle body 2 so that an operator can reach behind the door leaf 1 in the gap and open it completely.

In addition to the door leaf 1 already described, the motor vehicle door also has a locking member 4, 5, 6, with the aid of which the door leaf 1 can be fixed in predetermined angular positions in comparison to the motor vehicle body 2. In the exemplary embodiment, the locking member 4, 5, 6 is provided with an adjusting rod 4 and a latching arm 5 connected to it equipped. The locking arm 5 merges into a counter-stop 6 at the end, as shown in detail in FIG Fig. 3 is shown.

The locking member 4, 5, 6 is evidenced by the Fig. 1 and 2nd rotatably and pivotably connected to the motor vehicle body 2 via a swivel joint 7. The pivot joint 7 defines a pivot point at a distance from the pivot axis of the door leaf 1, which is predetermined by the hinge axes 3.

As a result, the locking member 4, 5, 6, due to the described eccentric linkage to the motor vehicle body 2, when the door leaf 1 is moved, performs extension and retraction movements relative to the door leaf 1 in question. For this purpose, the locking member 4, 5, 6 protrudes into an opening 8 one side edge of the door leaf 1 into this (cf. Fig. 1 and 2nd ).

To fix the door leaf 1 in the predetermined angular positions compared to the motor vehicle body 2, the locking arm 5 equipped with recesses interacts with only in the Fig. 1 and 2nd indicated and opposing locking members 9 inside the door leaf. The locking members 9 can be spring-loaded sliding or rolling bodies which press against the locking arm 5 with the force of their springs. As soon as the locking members 9 dip into a locking recess of the locking arm 5 of the locking member 4, 5, 6, the door leaf 1 is fixed in the associated angular position and unintentional movements of the door leaf 1 are prevented.

In its basic structure, the motor vehicle door also has at least one actuator 10, 11 operating on the door leaf 1, which is in particular in the Fig. 4 can be seen. In the exemplary embodiment, the actuator 10, 11 in question is arranged in the area of the swivel joint 7, which of course is not mandatory and only applies as an example. The actuator 10, 11 in turn consists of an electric motor 11 and one connected to the electric motor 11 Adjusting nut 10 together, which interacts with the adjusting rod 4 of the locking member 4, 5, 6.

Actually, the actuator 10, 11 is connected to the locking member 4, 5, 6 and drives the locking member 4, 5, 6 directly to adjust the door leaf 1, namely linearly. This is accomplished within the scope of the exemplary embodiment in such a way that the electric motor 11, as part of the actuator 10, 11, sets the adjusting nut 10 in rotation. The adjusting rod 4 of the locking member 4, 5, 6 is immersed in the adjusting nut 10. The adjusting nut 10 and the adjusting rod 4 are equipped with mutually corresponding threads. In this way, rotations of the adjusting nut 10 lead to the adjusting rod 4 being moved back and forth linearly. The same then also applies to the locking member 4, 5, 6 as a whole.

In the Fig. 3 an opening movement of the door leaf 1 with the aid of the locking member 4, 5, 6 is shown schematically. The dot-dash position of the locking member 4, 5, 6 corresponds to the starting position, whereas the solid representation marks the end of the adjustment path X of the locking member 4, 5, 6. That is, for the opening movement of the door leaf 1, the locking member 4, 5, 6 in the illustration according to Fig. 3 moved to the left, as indicated by a corresponding arrow. Of course, the locking member 4, 5, 6 can also perform a countermovement to retract, which, however, in the Fig. 3 is not shown.

As a result of the issuing movement after the Fig. 3 causes the actuator 10, 11, which drives the locking member 4, 5, 6 directly, that is without interposed transmission elements or the like, at least a gap opening of the door leaf 1. This gap-wise opening of the door leaf 1 typically corresponds to a gap in the order of 100 mm to 200 mm compared to the motor vehicle body 2, so that an operator can reach behind the door leaf 1 in this gap and open it completely.

The actuator 10, 11 designed as a linear control element thus ensures that, with the aid of the locking element 4, 5, 6 and its front counter-stop 6, a corresponding stop 12, 13 on the door leaf 1 is shown in the illustration Fig. 3 is also moved to the left. Since the stop 12, 13 is connected to the door leaf 1, the displacement of the locking member 4, 5, 6 described leads to the fact that the counter-stop 6 in the Fig. 3 Adjustment path x shown and moves away from the swivel joint 7 by this amount. This has the immediate consequence that the door leaf 1 is opened at least in a gap with respect to the motor vehicle body 2.

As already explained, for this purpose the locking member 4, 5, 6 has the adjusting rod 4 at the end, which interacts with the adjusting nut 10 of the actuator 10, 11. That is, the adjusting rod 4 is acted upon by the adjusting nut 10 of the actuator 10, 11 for linear adjustment of the locking element 4, 5, 6. During this process, the locking member 4, 5, 6 and with it the counter-stop 6 by the amount of travel x or the adjustment in the example shown after Fig. 3 shifted to the left. Since the counter-stop 6 interacts with the door-leaf-side stop 12, 13 and this is also shown in the illustration Fig. 3 Adjusted to the left, the door leaf 1 is at least partially opened as a result or experiences the described gap-wise opening.

In the exemplary embodiment and according to the preferred embodiment, a drive 14, 15, 16, 17 is implemented in addition to the actuator 10, 11 already described. The drive 14, 15, 16, 17 can in principle also be dispensed with because the actuator 10, 11 can in principle also drive the locking element 4, 5, 6 so directly that the locking element 4, 5, 6 completely opens the door leaf 1 if necessary and possibly closes.

In the context of the exemplary embodiment, however, the design is such that the actuator 10, 11 ensures that the door leaf 1 is opened in a gap with respect to the motor vehicle body 2. In contrast, the drive 14, 15, 16 effects a complete opening / closing of the door leaf 1 with respect to the motor vehicle body 2. That is, with the aid of the drive 14, 15, 16, 17 the door leaf 1, which is initially opened in a gap, can be fully opened. Complete closure of the door leaf 1 or both is also possible and is included in the invention.

For this purpose, the drive 14, 15, 16, 17 works via the stop 12, 13 on the door leaf 1 on the locking member 4, 5, 6. In fact, the drive 14, 15, 16 interacts with the counter stop 6 via the stop 12, 13 on locking member 4, 5, 6 (cf. Fig. 3 ).

It can be seen that the stop 12, 13 on the door leaf 1 is adjustable. This is based on a comparative consideration of the specific design according to the Fig. 4 and 5 clear. In fact, the stop 12, 13 has two drive disks 12, 13 that can be moved relative to one another. The first drive pulley 12 interacts with the locking member 4, 5, 6, as will be explained in more detail below. The other second drive pulley 13 is designed as a second drive pulley 13 connected to the drive 14, 15, 16, 17.

In fact, the drive 14, 15, 16, 17 is initially composed of an electric motor 14 and a Bowden cable 15, 16 connected to the electric motor 14 or another transmission element 15, 16. With the help of the electric motor 14, a core 16 of the Bowden cable 15, 16 can be moved linearly back and forth with respect to the associated sheath 15, as indicated by a double arrow in FIG Fig. 4 and 5 indicates. As a result of this, the second drive pulley 13 connected to the core 16 via a connection piece 17 at the end is pivoted, specifically in comparison to an axis 18. In fact, the axis 18 is formed by a pivot which is connected to a connection plate 19. The connection plate 19 is for its part fixed on the door leaf 1. The two drive disks 12, 13 are now designed to be rotatable in comparison with the axis 18 opposite the connection plate 19. As a result, the stop 12, 13 on the door leaf 1, which is formed together by the two drive disks 12, 13, is designed to be adjustable. In addition, the two drive disks 12, 13 are also elastically coupled to one another via springs 20, 21 and can consequently be moved relative to one another.

The way it works is as follows. In order to open the handleless door leaf 1 of the motor vehicle side door described in the exemplary embodiment with respect to the motor vehicle body 2, at least in gaps, the actuator 10, 11 is first acted upon. The actuator 10, 11 ensures that the locking member 4, 5, 6 in the representation according to Fig. 3 is moved to the left. As a result of this, the stop 12, 13 also moves by the amount x of the associated adjustment path shown there.

Transferred to the specific embodiment according to Fig. 4 and 5 this means that the counter-stop 6 of the locking member 4, 5, 6 moves against the first drive pulley 12 and pivots it in a clockwise direction compared to the axis 18. During this process, the first drive pulley 12 takes the second drive pulley 13 with it via the spring 21, so that the stop 12, 13 as a whole completes the adjustment path x as described. Since the drive 14, 15, 16, 17 is virtually rigid at this point in time, the displacement of the stop 12, 13 on the door leaf 1 with the aid of the linearly moved locking member 4, 5, 6 ensures that the door leaf 1 opens at least the described gap performs. During this process, the actuator 10, 11 acts on the first drive pulley 12 until it moves against a stop 22. At the same time, this actuates a sensor or switch 23 which switches off the actuator 10, 11.

The signal from the sensor 23 or switch 23 can now also be used to start the drive 14, 15, 16, 17. This process ensures that the core 16 of the Bowden cable 15 in the representation according to the Fig. 5 is drawn in or moved there to the left. As a result, the drive pulley 13 connected to the drive 14, 15, 16, 17 performs a counterclockwise movement compared to the axis 18. Since the first drive pulley 12 rests against the stop 22 of the second drive pulley 13, this counterclockwise movement of the second drive pulley 13 is directed to the first drive pulley 12 transmitted.

Since the first drive pulley 12 rests against the counter-stop 6 of the locking member 4, 5, 6, this process corresponds to the fact that the drive 14, 15, 16, 17 or the drive movement initiated by it is supported or against the locking member 4, 5, 6 . on the locking member 4, 5, 6 works.

The door leaf 1 is completely opened by the common counterclockwise movement of the two drive disks 12, 13 about the axis 18 compared to the connection plate 19. This process ends as soon as the second drive pulley 13 with a nose 24 reaches a further sensor or switch 25. When it is applied, this ensures that the drive 14, 15, 16 is switched off.
