DETAILED DESCRIPTION

(22) A first embodiment of a cover apparatus 1 for a motor vehicle body 2 of a motor vehicle 3 is illustrated in FIG. 1. The cover apparatus 1 has a movable covering element 4 and a movement device 5, with the aid of which the covering element 4 can be moved relative to the motor vehicle body 2.

(23) The covering element 4 is provided for covering a filling connector 7 of an energy supply element (not shown in greater detail). In this embodiment, the filling connector 7 is arranged on a receptacle element 35 of shell-like configuration that is configured so as to lie opposite the covering element 4. The receptacle element 35 is arranged in a vehicle body opening 40 of the motor vehicle body 2 and, in the installed state, is fixed with respect to the motor vehicle body 2.

(24) The receptacle element 35 has a receptacle opening 6 that is configured for receiving the energy supply element and can be closed completely or partially by way of the covering element 4. Furthermore, the receptacle element 35 has a shell-like configuration that is configured as a carrier of a filling gauge 32.

(25) In the illustrated embodiment, the energy supply element is a filling connector 7 in the form of a plug that is configured as a plug-in apparatus. The filling connector 7 is connected to a drive unit of the motor vehicle 3 in the form of a battery. However, the filling connector also could be a fuel nozzle, the drive unit could be an internal combustion engine and a tank could be provided to receive liquid fuel.

(26) The movement device 5 comprises a first guide rail 8 and a second guide rail 9 that are spaced apart and parallel to one another. The two guide rails 8, 9 extend predominantly in the direction of a vehicle body longitudinal axis x, and are offset with respect to one another in the direction of a vehicle body transverse axis y and a vehicle body vertical axis z. The guide rails 8, 9 overlap over their guide length l. Thus, each of the two guide rails 8, 9 has the guide length l, and it is not necessary for a value of the guide length l of the guide rails 8, 9 to be identical. As a result, the guide rails 8, 9 overlap over a region that is smaller than or equal to their guide length l.

(27) The movement device 5 further comprises a third guide rail 10 and a fourth guide rail 11 that are transverse to the first guide rail 8 and the second guide rail 9. Therefore, the covering element 4 can be moved in the direction of the vehicle body longitudinal axis x with the aid of the first guide rail 8 and the second guide rail 9, and can be moved in the direction of the vehicle body transverse axis y with the aid of the third guide rail 10 and the fourth guide rail 11.

(28) The third guide rail 10 and the fourth guide rail 11 can be moved relative to the first guide rail 8 and the second guide rail 9, which are arranged rigidly on the motor vehicle body 2. Furthermore, the third guide rail 10 and the fourth guide rail 11 are connected rigidly to one another with the aid of an adjusting element 12. In this way, the third and fourth guide rails 10 and 11 carry out a common movement.

(29) The adjusting element 12 is coupled to an actuating element 13 that is configured to be displaced linearly in the direction of the vehicle body longitudinal axis x with the aid of a linear rail 14. Thus, a displacement of the actuating element 13 causes a corresponding translational movement of the adjusting element 12.

(30) The covering element 4 is of plate-shaped configuration and is arranged in a manner that faces the movement device 5. The covering element 4 has a first holding arm 15 and a second holding arm 16 that extend into and connect to the movement device 5. The holding arms 15, 16 are attached to an inner face 25 of the covering element 4, and the inner face 25 faces the receptacle opening 6.

(31) First and second guide elements 18, 19 are arranged respectively at the ends 17 of the holding arms 15, 16 that face away from the covering element 4 and serve for positive guidance of the covering element 4 in the guide rails 8, 9, 10, 11.

(32) The first guide element 18 is on the first holding arm 15 and engages into both the first guide rail 8 and the third guide rail 10. The third guide rail 10 is above the first guide rail 8 in the direction of the vehicle body vertical axis z. In this way, the first guide element 18 can be moved in the first guide rail 8 along the vehicle body longitudinal axis x, and in the third guide rail 10, which extends transverse to the first guide rail 8 predominantly in the direction of the vehicle body transverse axis y. The third guide rail 10 also is set in the direction of the vehicle body vertical axis z.

(33) To achieve a flush arrangement of the covering element 4 with the motor vehicle body 2 in the closed position where the covering element 4 closes the receptacle opening 6 completely, an end 30 of the first guide rail 8 has an eye 31 that extends in the direction of the covering element 4 at its end 30 to limit the closing movement. More particularly, the first guide rail 8 has a curvature at its end 30, and the curvature is configured in the direction of the covering element 4 so that that the outer face 26 of the covering element 4 can be arranged flush with the outer skin 24 in the closed position. The eye 31 is oriented in the direction of the surroundings or in the direction of the covering element 4 and is necessary, since, in the open position, the covering element 4 is arranged behind an outer skin 24 of the motor vehicle body 2 as viewed from the outside.

(34) The second guide element 19 is arranged on the second holding arm 16 in a functionally identical manner. More particularly, the second guide element 19 is arranged to engage both into the second guide rail 9 and into the fourth guide rail 11. To this end, the fourth guide rail 11 is above the second guide rail 9 in the direction of the vehicle body vertical axis z. In this way, the second guide element 19 can be moved in the second guide rail 9 along the vehicle body longitudinal axis x, and in the fourth guide rail 11, which extends transverse to the second guide rail, predominantly in the direction of the vehicle body transverse axis y. In the case of the fourth guide rail 11 also is set in the direction of the vehicle body vertical axis z.

(35) For secured guidance, the covering element 4 has an element bar 21 on its element face 20 that faces away from the holding elements 18, 19. The element bar 21 is arranged to engage into a supporting rail 22 that delimits the receptacle opening 6 and is formed with the aid of the receptacle element 35.

(36) With the aid of the guide rails 8, 9, 10, 11, the covering element 4 can be positioned, starting from its closed position, along the vehicle body transverse axis y in the direction of a vehicle body interior space 23, and therefore below the motor vehicle body 2. Thus, the covering element 4 can be displaced below the outer skin 24 of the motor vehicle body 2 to open the receptacle opening 6. If the receptacle opening 6 is covered, an outer face 26 of the covering element 4 is arranged flush with the outer skin 24.

(37) FIGS. 1 to 8 should not be understood such that the movement apparatus 5 is arranged in front of the outer skin 24, and is therefore visible. Rather the movement apparatus 5 is behind the outer skin 24 so as to face the vehicle body interior space 23 in the direction of the vehicle body transverse axis y. The illustrations have been selected for reasons of improved explanation.

(38) The movement device 5 is arranged above the plug-in apparatus 7 in the direction of the motor vehicle vertical axis z and is configured so as not to be visible from the outside even in the case of an open receptacle opening 6.

(39) In the first embodiment illustrated in FIGS. 1 and 3 to 5, the cover apparatus 1 can be actuated mechanically. To open the receptacle opening 6, the covering element 4 is to be pressed in the direction of the vehicle body transverse axis y, and is to be pushed manually in the direction of the vehicle body longitudinal axis x, until a latching element 27 is reached by way of latching into it. Force is to be exerted counter to a prestressing element 28 in the form of a gas pressure spring. To close the receptacle opening 6, the covering element 4 is to be pressed again against the latching element 27 in its opening direction, indicated with the aid of the arrow 41 in FIG. 17, so that the latching element 27 can be released and the covering element 4 and can move again with the aid of the prestressing element into its position, in which it closes the receptacle opening 6 completely. The latching element 27 preferably is configured in the form of what is known as a push-push element.

(40) Instead of the prestressing element 28 and the latching element 27 configured in the form of a push-push element, a second embodiment of the cover apparatus 1 is illustrated in FIGS. 2, 6 to 8 and 10 and uses an electric drive 29 which, by way of example, comprises a stepping motor as drive element. The movements of the covering element 4 are identical in the two exemplary embodiments, since the movement device 5 is also identical with the exception of the drive.

(41) FIGS. 9 and 10 serve for improved explanation. FIG. 9 illustrates the motor vehicle body 2 with the closed receptacle opening 6, and FIG. 10 shows a transparent illustration of the motor vehicle body 2 to make the arrangement of the cover apparatus 1 visible in the case of a closed receptacle opening 6 using the example of the second embodiment. It can thus be shown that the movement device 5 and at least the holding arms 15, 16 are always positioned completely below the outer skin 24, and thus between the outer skin 24 and the vehicle body interior space 23, both in the case of a closed receptacle opening 6 and even in the case of a merely partially open or completely open receptacle opening 6. Accordingly, the cover apparatus 1 can be arranged completely on an inner face of the motor vehicle body 2 and hence facing away from the outer skin 24.

(42) In a further refinement of the cover apparatus 1, a translucent charging tray can be provided to shine through in the direction of the outer skin 24.

(43) FIGS. 11 and 12 illustrate the cover apparatus 1 according to the invention in accordance with a third embodiment. As is the case with the cover apparatus 1 of the first embodiment, the cover apparatus 1 can be actuated mechanically. The receptacle element 35 has an element carrier 36 that extends in the direction of the vehicle body interior space 23. It is arranged more or less perpendicularly on the receptacle element 35, and is in one piece with the receptacle element 35.

(44) The element carrier 36 has the first guide rail 8 and the second guide rail 9 in an integrated manner. More particularly, the guide rails 8, 9 are configured in one piece with the element carrier 36. However, the guide rails 8, 9 can be produced independently of the element carrier 36, and then received on the element carrier 36.

(45) In this embodiment, the second guide rail 9 is inclined slightly with respect to the first guide rail 8, as a result of which a movement in the direction of the vehicle body transverse axis y is ensured in a simple way.

(46) The covering element 4 of the third embodiment has a single holding arm 15 for guidance purposes. The first guide element 18 is at its arm end 17 to be spaced away from the second guide element 19 at least in the direction of the motor vehicle longitudinal axis x. However, the covering element 4 of the third embodiment can have two holding arms 15, 16 for receiving the guide elements 18, 19. The holding arms 15, 16 of the first and the second embodiments might be configured as a single holding arm 15. For the exact guidance of the covering element 4 along the guide rails 8, 9, the configuration of at least two guide elements 18, 19 on the holding arm 15, which can be one piece or two pieces is preferred so that movement of the covering element 4 can be realized without jamming in the direction of the vehicle body longitudinal axis x and in the direction of the vehicle body transverse axis y.

(47) The prestressing element 28 (configured in the form of a spiral spring) of the third embodiment is supported on a guide rod 34 that extends in the direction of the vehicle body longitudinal axis x, as can be gathered from FIG. 12.

(48) Above the filling gauge 32 in the direction of the motor vehicle vertical axis z, the receptacle element 35 has an illumination element 33 in the form of an LED light strip for improved visibility of the filling gauge 32. The illumination element 33 is actuated with the aid of a control element 42 in the form of a switch that is actuated when the closed position of the covering element 4 is reached or left.

(49) The element bar 21 of the covering element 4 of the third embodiment further has a third guide element 43 in the form of a cylindrical pin that is configured to engage into the supporting rail 22.

(50) FIGS. 13 and 14 illustrate the cover apparatus 1 according to a fourth embodiment where an electric drive 29 is provided in contrast to the cover apparatus 1 of the third embodiment. The electric drive 29 has a drive element 44 in the form of the stepping motor. The electric drive 29 also has a drive spindle 38 and a connecting element 39 in the form of a nut that connects the actuating element 13 to the drive spindle 38 and can be moved on and along the drive spindle 38.

(51) FIGS. 15 to 17 and FIGS. 18 to 20 are perspective illustrations of the closed position, the intermediate position and the open position of the cover apparatus of the third embodiment and the fourth embodiment.

(52) A cover apparatus 1 of a fifth embodiment is shown in FIG. 21 and is substantially in accordance with the third and fourth embodiments. The movement apparatus 5 of the fifth embodiment has the actuating element 13 which, in the case of the electric drive, is driven directly (i.e. immediately) via the drive spindle 38, and therefore without the connecting element 39, or can slide along on the guide rod 34 in the case of the mechanical drive.

(53) The last three embodiments are suitable for simplified assembly of the cover apparatus 1 on account of the guide rails 8, 9 being received on the receptacle element 35 and/or in the case of the configuration of the guide rails 8, 9 in the receptacle element 35 with the aid of the element carrier 36, since the entire cover apparatus 1 in the form of a finished kit that can be assembled is suitable for assembly on the motor vehicle body 2 with the aid of the holder 37. In this way, inexpensive assembly can be achieved, in particular in the case of these embodiments.
