Description

[0023] FIG. 1 shows a system comprising a cover for covering a charging socket of an electric car according to the invention, with the cover in a closed position;

[0024] FIG. 2 shows the system from FIG. 1, with the cover in an intermediate position; and

[0025] FIG. 3 shows the system from FIGS. 1 and 2, with the cover in an open position.

[0026] The drawings are schematic and partially simplified illustrations to provide an understanding of and to describe the invention.

[0027] The system 1 according to the invention shown in the drawings comprises a cover 2, which can be pivoted back and forth about a first pivot axis 3 between a closed position, which is shown in FIG. 1, and an open position, which is shown in FIG. 3. FIG. 2 shows an intermediate position of the cover 2 between the closed position and the open position.

[0028] In the closed position, the cover 2 is located in a charging opening 4 of a body part 5, such as a fender of a motor vehicle, which is not shown further, closes the charging opening 4, and covers a charging socket 6, which is recessed in the charging opening 4 or located behind the charging opening 4. The charging socket 6 is used for charging a driving battery, which is a rechargeable battery, of a motor vehicle, which is an electric car.

[0029] When closed, the cover 2 is flush with the body part 5, which is to say an outer side 7 of the cover 2 is flush with an outer side 8 of the body part 5 in a region of the body part 5 surrounding the charging opening 4 (FIG. 1).

[0030] When open, the cover 2 projects, for example perpendicularly in the exemplary embodiment, from the body part 5 on the outer side 8 of the body part 5 (FIG. 3).

[0031] The cover 2 comprises a hinge arm 9, which projects rigidly from an inner side 12 of the cover 2 near an edge of the cover 2. In the exemplary embodiment, the hinge arm 9 is integral with the cover 2. The first pivot axis 3, about which the cover 2 can be pivoted, extends parallel to the outer side 7 of the cover 2 and the outer side 8 of the body part 5, wherein the first pivot axis 3 is situated on an inner side 11 of the body part 5, laterally next to the charging opening 4. An end of the hinge arm 9 lying furthest from the cover 2 is mounted so as to be pivotable about the first pivot axis 3, whereby the cover 2 can also be pivoted about the first pivot axis 3. During pivoting, the cover 2 carries out a movement on a circular path about the first pivot axis 3.

[0032] The hinge arm 9 is curved and, as viewed parallel to the first pivot axis 3, has an approximately V shape having approximately circular arc-shaped legs and an apex rounded in an arc shape. When the cover 2 is open, one of the legs of the “V” of the hinge arm 9 is located on the inner side 11 of the body part 5, and the apex of the “V” embraces the edge of the charging opening 4 in one location.

[0033] For opening and closing the cover 2, the system 1 according to the invention comprises an actuator 10, which in the exemplary embodiment is an electromechanical actuator 10 and comprises a gear motor. The drawings show the actuator 10 as a graphical symbol in a simplified illustration. The actuator 10 pivots the hinge arm 9 about the first pivot axis 3, wherein the actuator 10 also pivots or moves the cover 2 about the first pivot axis 3 on a circular arc. The cover 2 can be pivoted about the pivot axis 3, back and forth between the closed position and the open position, by way of the actuator 10.

[0034] “Opening” shall be understood to mean moving or pivoting the cover 2 from the closed position into the open position, and “closing” shall be understood to mean moving or pivoting the cover 2 from the open position into the closed position.

[0035] According to the invention, the actuator 10 is activated for opening the cover 2 in that the cover 2 is moved from the closed position inwardly, which is to say a short distance in a closing direction beyond the closed position. The closing direction is a movement of the cover 2 from the direction of the open position in the direction of the closed position, and possibly beyond the closed position, inwardly to the inner side 11 of the body part 5.

[0036] A multiplication member 13, which in the exemplary embodiment comprises a transfer body 14, which in the exemplary embodiment is a pivoting lever, is disposed on the inner side 12 of the cover 2 for activating the actuator 10. The transfer body 14 can be pivoted about a second pivot axis 15.

[0037] Spaced apart from the second pivot axis 15, the transfer body 14 has a protrusion 16, which projects in the direction of the cover 2 and against which an elevation 17 at the inner side 12 of the cover 2 strikes when the cover 2 is moved from the closed position inwardly. The elevation 17 at the inner side 12 of the cover 2 is referred to as an actuating element here and, in the exemplary embodiment, has the shape of a pin. When moved from the closed position inwardly, the cover 2 pivots the transfer body 14 in an actuating direction by way of the actuating element thereof.

[0038] At one end, the transfer body 14 has an angled section 18, which strikes against a push button 19 and actuates the push button 19 when the transfer body 14 is pivoted from the closed position inwardly in the actuating direction as a result of the movement of the cover 2. Upon actuation, the push button 19, which, generally speaking, can also be interpreted as an electrical switching unit, activates the actuator 10 so that the actuator 10 opens the cover 2, which is to say pivots it about the first pivot axis 3 in the circular arc into the open position.

[0039] Instead of activating the actuator 10, or in addition to activating the actuator 10, it is also possible for a different function to be triggered by way of the electrical switching unit 20.

[0040] A distance between the angled section 18 of the transfer body 14 and the second pivot axis 15 is greater than the distance between the protrusion 16 and the second pivot axis 15, whereby, upon the actuation of the electrical switching unit 20, a path from the cover 2 to the electrical switching unit 20 is multiplied by way of the transfer body 14 of the multiplication member 13. “Path multiplication” shah be understood to mean that the path of the angled section 18 is longer than the path of the cover 2 from the closed position inwardly. As a result, a short path of the cover 2 from the closed position inwardly suffices for actuating the electrical switching unit 20 and activating the actuator 10.

[0041] The angled section 18 of the transfer body 14 allows components on the inner side 11 of the body part 5 to be circumvented. In the exemplary embodiment, the angled section 18 protrudes through an opening 21 of a charging bay body 22.

[0042] The distance between the protrusion 16 of the transfer body 14, in which the elevation 17 of the cover 2 strikes against the transfer body 14, and the second pivot axis 15 can also be interpreted as a first lever arm 23, and the distance between the angled section 18, by way of which the transfer body 14 actuates the push button 19 or the electrical switching unit 20, and the second pivot axis 15 can also be interpreted as a second lever arm 24. For multiplying the path from the cover 2 to the push button 19 or to the electrical switching unit 20, the second lever arm 24 is longer than the first lever arm 23.

[0043] In the exemplary embodiment, the two lever arms 23, 24 project from the second pivot axis 15 in the same direction. However, designs in which the two lever arms 23, 24 project from the second pivot axis 15 in opposite directions or in differing directions are also possible (not shown).

[0044] At an end located opposite the angled section 18, the transfer body 14 comprises a pin, serving as a stop 25, which rests against an abutment 26 when the cover 2 has not been moved from the closed position inwardly. The stop 25 and the abutment 26 form a pivot angle limiter 27, which limits a pivot angle of the transfer body 14 counter to the actuating direction.

[0045] In the exemplary embodiment of the invention, the first pivot axis 3, about which the cover 2 can be pivoted by way of the hinge arm 9 thereof, and the second pivot axis 15, about which the transfer body 14 can be pivoted, are disposed parallel to one another and parallel to a tangential plane with respect to the outer side 8 of the body part 5 on the inner side 11 of the body part 5.

[0046] The charging bay body 22 is fixedly disposed at the inner side 11 of the body part 5 and has an opening, which is congruent with the charging opening 4 in the body part 5. In the charging bay body 22, the two pivot axes 3, 15 are stationary, the hinge arm 9 of the cover 2 can be pivoted about the first pivot axis 3, and the transfer body 14 of the multiplication member 13 can be pivoted about the second pivot axis 15, and the actuator 10, the electrical switching unit 20, and the charging socket 6 are stationary. When the cover 2 is open, the charging socket 6 is freely accessible through the charging opening 4 in the body part 5 for plugging in a charging cable for a driving battery of the motor vehicle or electric car.

[0047] In contrast to the schematic illustrations in the drawings, the transfer body 14 does not conceal the charging socket 6, but the transfer body 14 is disposed in the charging bay body 22 next to, above, or beneath the charging socket 6 so as not to impede the plugging-in of the charging cable.
