Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The invention is described in detail in the following on the basis of an example embodiment with reference to the drawings. The drawings show:

[0020] FIG. 1 a schematic cross-sectional diagram of an example embodiment of a charging connection of a motor vehicle when in an opened state, and

[0021] FIG. 2 is a schematic cross-sectional diagram of the charging connection of the motor vehicle in the transition between the opened state and a closed state.

DETAILED DESCRIPTION OF THE INVENTION

[0022] FIG. 1 shows a partial illustration of a motor vehicle 1 with a charging connection 2 for connecting a charging cable 3 with a charging cable plug 4, for example for charging a vehicle battery via a charging network.

[0023] FIGS. 1 and 2 show a schematic cross-sectional diagram of the charging connection 2 of the motor vehicle 1, respectively. FIG. 1 shows the charging connection 2 in the opened state and FIG. 2 shows the charging connection 2 of the motor vehicle 1 in the transition from the opened state to the closed state.

[0024] The charging connection 2 is configured with a charging socket 5 and with a charging socket cover 6. The charging connection 2 is arranged in the motor vehicle 1 such that the charging socket cover 6 covers and closes an opening 7 in the vehicle body 8 in a first operating position and the charging socket 5 is arranged in the first operating position shielded behind the charging socket cover 6. In this first operating position, the charging socket 5 is not available for connection to the charging cable plug 4; the charging connection 2 is in a closed state.

[0025] In a second operating position, the charging socket cover 6 releases the opening 7 and is arranged behind the opening 7 in a free space 9 of the body 8, for example adjacent to the charging socket 5, as shown in FIG. 1. In the second operating position, the charging socket 5 is arranged adjacent to the opening 7 in order to be available for a charging cable plug 4 to be connected. For this purpose, the charging socket 5 is displaced forward towards the opening 7.

[0026] To achieve this, the charging socket 5 and the charging socket cover 6 are displaceably arranged or mounted between the first operating position and the second operating position.

[0027] As can be seen in FIGS. 1 and 2, the charging socket 5 is electrically connected by means of at least a first lever transmission 10. For example, such a first lever transmission 10 is arranged on one side of the charging socket 5, or alternatively, such a first lever transmission 10 can also be arranged on both sides of the charging socket 5. The first lever transmission 10 is used to electrically connect the charging socket 5 to the vehicle battery to be able to power and charge it from a charging network.

[0028] It is not shown in FIGS. 1 and 2 that the charging socket 5 is displaceably mounted by means of at least one driving mechanism and/or by means of at least a second lever transmission or another transmission and/or actuator.

[0029] It is also not shown that the charging socket 6 is displaceably mounted by means of at least one driving mechanism and/or by means of at least a third lever transmission or another transmission and/or actuator. This allows the charging socket cover 6 to be arranged in the first operating position in front of the charging socket 5 and the charging socket cover 6 to be arranged to the side of the charging socket 6 in the second operating position.

[0030] In the example embodiment shown, the at least one first lever transmission 10 is a two-stroke device 11 comprising two levers 12 that are coupled to each other as a hinge in a v-shaped manner.

[0031] The at least one first lever transmission 10 has a fixed bearing 13 and a displaceable bearing 14, wherein the fixed bearing 13 is arranged fixed to the body and the displaceable bearing 14 is guided by means of a guide 15, for example. The guide 15 is configured as a linear guide, for example, or as a curved guide 15. The guide 15 is preferably also arranged so that it is fixed to the body. Alternatively, the guide 15 can also be dispensed with. The displaceable bearing 14 is fixedly connected to the charging socket 5, wherein the electrical connection between the charging socket 5 and the displaceable bearing 14 is made via the connection 20, which is configured as a bracket, for example.

[0032] The two-stroke device 11 with its two levers 12 is configured such that the levers 12 that are coupled to each other as a hinge in a v-shaped manner are hinged to the bearings 13, 14, wherein there is a hinged connection between the two levers 12. A first lever 12 of the two levers 12 is hinged at a first of end 16 of its ends 16, 17 at the fixed bearing 13 and the second lever 12 of the two levers 12 is hinged at a first end 16 of its ends 16, 17 at the displaceable bearing 14, wherein the levers 12 are hinged together at their respective second end 17.

[0033] Furthermore, it can be seen in FIGS. 1 and 2 that the at least one fixed bearing 13 of the at least one lever transmission 10 or at least one fixed bearing 13 of a lever transmission 10 is electrically connected to a voltage source 19 via an electrical connection 18. Thus, the electrical supply and mechanical displaceability of the charging socket 5 can be achieved by means of the lever transmission 10.

[0034] It is advantageous if the electrical connection 18 is a rigid, fixed, in particular rod-shaped, line. The line cross-section can be about 150 mm.sup.2 to 200 mm.sup.2 or more. Thus, high current levels can be used to perform a charging operation.
