Description

The invention relates to a motor closure arrangement for an access opening of a motor vehicle body.

In motor vehicles, closure arrangements are known as manually operated tank lids or, in the case of electrically powered motor vehicles, as charging plug lids. From the DE 10 2016 110 869 A1 Such a closure arrangement with an electromotively movable cover is known, which closes in its closed position an access opening to an interior in which an electrical charging plug is arranged, and which is housed in its opening position within the interior and adjacent to the access opening. The movement of the cover between the closed position and the open position is determined by a guide mimic which, in one embodiment, has guide rails which have a bend between a lift region and a push region.

The object of the invention is in contrast to provide a compact and simple motorized closure assembly.

This object is achieved by a motorized closure assembly with the features of claim 1.

The motor-driven closure arrangement according to the invention has a motor-driven cover with which an access opening of the motor vehicle body is opened or closed as required. In the interior, for example, a charging plug for charging a traction battery of the relevant motor vehicle can be accommodated. The charging plug is mechanically protected and shielded when the cover is closed and is accessible when the cover is open for inserting a mating connector.

It is provided in the interior arranged Führungsmimik provided by the lid during the process between its open position within the interior and adjacent to the access opening and its closed position in which the lid closes the access opening, can be moved. The leadership mimic has at least one jump-free extending longitudinal guide rail, which is arranged in the interior. In the present case, a jump-free course is understood to mean a shape in the longitudinal direction of the longitudinal guide rail, which is not necessarily rectilinear, but does not have any curvature jumps. In particular, the longitudinal guide rail has no lifting area, but follows, for example, substantially the contour of the motor vehicle body in the interior. Particularly preferably, the longitudinal guide rail is formed absolutely straight and is formed by an extruded profile rail body, which is inexpensive and can be produced with high precision.

The management mimic has a Mitnehmerkulisse with at least one longitudinal guide rail longitudinally inclined Mitnehmerkulissen-Hubschlitz, in which a corresponding guide pin is guided. The Hubschlitz the Mitnehmerkulisse defines the lifting movement of the lid at the beginning of the opening movement or at the end of the closing movement of the lid. In principle, the Mitnehmerkulisse can be fixed directly to the cover, and the corresponding guide pin can be slidably mounted in the longitudinal guide rail. Particularly preferably, however, it is provided that the Mitnehmerkulisse is guided directly in the guide rail, and that the guide pin is fixed to the cover.

The guide pin is guided in the Hubschlitz the Mitnehmerkulisse such that in a process of Mitnehmerkulisse in the guide rail or the guide pin in the longitudinal guide rail at the beginning of the opening movement of the lid of the lid following the Hubschlitz performs a lifting movement into the interior, and then a sideways directed Performs longitudinal movement along the longitudinal guide rail.

As a result, a simple management facial expression is realized, which consists essentially of a simply shaped and therefore inexpensive to produce longitudinal guide rail, for example, consisting of a sheet metal body and also easy and inexpensive to produce entrainment gate and a simple bolt.

The guide mimic preferably has exactly two longitudinal guide rails, which are arranged parallel to one another in the interior, and in each of which a driving cam is guided. One of the two Mitnehmerkulissen has two Hubschlitze, the other Mitnehmerkulisse has a single Hubschlitz. In the total of three Hubschlitzen a total of three guide pins are guided, which are fixed, for example, on the lid. The lid is thus stored at three points which define a triangle that is as simultaneous as possible.

According to a particularly preferred embodiment, a tensioning means is provided, for example a tension spring, by which the cover is pretensioned in relation to the entrainment gate in the open lifting position of the cover. As a result, the lid is held in its retracted opening position, as long as he does not have to perform the lifting movement along the Hubschlitze forcibly.

The guide mimic preferably has a mechanical stop which delimits the closing movement of the cover along the longitudinal guide rail in such a way that upon further movement of the entrainment gate in the longitudinal guide rail, the cover can forcibly perform only one lifting movement along the inclined lifting slots.

According to a preferred embodiment, the actuation of the Mitnehmerkulisse in the guide rail or the guide pin in the guide rail is effected by a train-pressure cable, which in turn is driven, for example, an electric motor. Due to the rigid tension-compression cable, both a pulling movement and a pressure movement can be reliably transmitted to the parts guided in the guide rail.

Preferably, the longitudinal guide rail has a Drahtführungsnut for guiding the train-pressure-rope. The wire guide groove is preferably undercut in cross-section such that the tension-compression cable can not escape from the wire guide groove.

As an alternative to the actuation of the entrainment gate by an electromotive-driven train-pressure cable, the longitudinal movement of the Mitnehmerkulisse in the guide rail can also be done directly by an electric linear drive. As a result, a very compact leadership facial expression is provided.

In the following an embodiment of the invention will be explained in more detail with reference to the drawings. Show it:

• 1 a bottom view of a motorized shutter assembly,
• 2 a longitudinal section of the motor closure assembly of 1 in the closed position of the lid,
• 3 the closure arrangement of 2 in the opening position of the lid, and
• 4 a cross section of a section of the closure assembly of 1-3 ,

The figures show various views and sections of an electromotive shutter assembly 10 for an access opening 13 in a motor vehicle body 12 , Through the access opening 13 is an interior from the outside 14 accessible, in which a charging plug 16 for charging a traction battery of the motor vehicle is arranged. Under the interior 14 in the present case, the entire space within the body 12 understood by the body 12 on the one hand and an interior wall 18 is limited or defined.

The access opening 13 is by a movable cover 20 closed in its closed position, as in the 1 and 2 shown. In its open position is the lid 20 in the interior 18 adjacent to the access opening 13 placed so that it is open as in the 3 shown.

The closure arrangement 10 has a leadership facial expressions through which the lid 20 is constrained between its closed position and its open position. The lid 20 is from a lid body 22 formed and has in its edge regions a circumferential sealing lip 24 on, through which a largely hermetic seal of the interior 14 opposite the outside with the lid closed 20 is ensured.

The management mimic consists essentially of three parts, namely two longitudinal guide rails arranged in the same plane relative to one another 30 . 70 , in each case a driving scenery 40 . 72 in the longitudinal guide rails 30 . 70 and three guide pins 43 . 45 . 74 , like in the 1 shown. The two longitudinal guide rails 30,70 are in the present case of a slightly and constantly bent extruded profile rail body 30 ' formed, however, the guide rail or the extruded profile rail body 30 ' alternatively be formed completely straight.

As in particular in the 4 is reproduced, the rail body 30 ' in the longitudinal direction an undercut Mitnehmerut 32 and in the bottom wall 33 the driver groove 32 an undercut Drahtführungsnut 34 on. In the carrier groove 32 is that of a sheet metal body 40 ' formed driving scenery 40 slidably and captively guided in the longitudinal direction.

The one driving set 40 has two mutually parallel Hubschlitze 421 . 422 on, the groove longitudinal direction in, for example, 20-70 ° is inclined to the longitudinal direction of the longitudinal guide rail 30 , The other driving scenery 72 in the second longitudinal guide rail 70 slidably mounted, has a single Hubschlitz.

The lid 20 has three guide pins 43 . 45 . 74 on, each in one of the Hubschlitze 421 . 422 are slidably mounted in the longitudinal direction of the slot. The three guide bolts 43 . 45 . 74 are each made of bolt arms 42 . 44 complains about the actual lid body 22 held. In this way, the two guide rails 30 . 70 directly on the interior wall 18 be fixed.

For preloading the lid body 22 in the retracted stroke position, as in the 3 is shown, is a tensioning means 46 provided, which is presently designed as a tension spring, and by the the lid 20 opposite the Mitnehmerkulisse 40 in the open lifting position of the lid 20 is biased. This will make the lid 20 held in its retracted or open opening position, as long as he does not have to perform the lifting movement forcibly.

At the body 12 is an end stop 48 provided that the closing movement of the lid 20 along the longitudinal guide rail 30 so limited that the lid 20 with further movement of the driving scenery 40 in the longitudinal guide rail 30 forcibly only one stroke along the inclined Hubschlitze 421 . 422 can perform.

The actuation of the two driving scenes 40 . 72 done by a pull-pressure rope 52 in the area of the longitudinal guide rail 30 in the wire guide groove 34 is guided. The train-pressure rope 52 is outside the two longitudinal guide rails 30 . 70 in a Bowden cable jacket 54 . 56 guided, which has two sections between which an electric rope drive motor 50 is arranged, the rope 52 drives. The Bowden cable jacket 54 . 56 between the two longitudinal guide rails 30 . 70 is laid in such a way that during a push opening movement in the first guide rail 30 a train opening movement in the second guide rail 70 is generated.

The opening of the closed lid 20 as he is in the 1 and 2 is shown, takes place in that the drive motor 50 is activated so that both Mitnehmerkulissen 40 . 72 be moved in the opening direction. The tensioning element 46 pulls the lid 20 Here, first from its closing stroke position in the open position in the interior 14 , Once the guide bolts 43 . 45 . 74 at the respective longitudinal end of the corresponding Hubschlitze 421 . 22 arrived, the longitudinal movement of the lid begins 20 in the longitudinal direction of the longitudinal guide rails 30 . 70 until the full lid opening position is reached as shown in the 3 is shown.

The closure of the opened lid 20 as he is in the 3 is shown, takes place in that the drive motor is activated such that both Mitnehmerkulissen 40 . 72 to be moved in the closing direction until the lid 20 to the end stop 48 strikes and by the continuing longitudinal movement of the Mitnehmerkulisse 40 . 72 the guide bolts 43 . 45 . 74 in the corresponding Hubschlitzen 421 . 422 the lifting movement of the lid 20 force it out of its open position into its closed position until the lid opens 20 in his in the 1 and 2 has arrived closed position shown.
