Definitions
- the invention relates to a charging connection device for a motor vehicle with a charging recess which is fixed to the vehicle in the operational state and which has at least two different charging connections and can be closed or opened by a movable recess cover, wherein at least one charging connection can be closed by a cover which is mounted so as to be pivotable about a pivot axis relative to the charging connection between a closed position closing the charging connection and a charging position opening the charging connection.
- Such a charging connection device is known from DE 10 2021 109 283 A1.
- An electric vehicle has a charging recess in the area of an outer body shell, in which several charging connections are provided in order to supply a drive system of the vehicle with power.
- One of the two charging connections is assigned a cover which is pivotally mounted about a pivot axis arranged adjacent to the charging connection between a closed position closing the charging connection and an open position releasing the charging connection.
- a pivot bearing of the cover is provided with a mechanical control which causes the cover to latch in the open position after an opening process and which releases the latching again when it is pivoted further in the opening direction.
- the mechanical control has a slotted guide according to the ballpoint pen principle.
- CN 114865382 A another charging connection device in which two charging connections can be closed or opened synchronously with one another by means of a pivotably mounted double cover.
- the double cover is pivotably mounted and has a mechanical cam control that forms a stop for the open position and a stop for the closed position of the double cover.
- the pivot bearing of the double cover is assigned a return spring arrangement that permanently applies torque to the double cover in one direction of rotation.
- the object of the invention is to provide a charging connection device of the type mentioned above, which enables an operator to have convenient and safe access to a charging connection.
- This task is solved by assigning a linear actuator to the cover, which is located on the front side and at a radial distance from the pivot axis of the cover on the cover is supported and is mounted in such a linearly movable manner that a linear displacement of the linear actuator inevitably causes a pivoting movement of the lid from the closed position into the charging position.
- the frontal support of the linear actuator on the lid ensures a particularly compact and easily detachable coupling between the linear actuator and the lid, so that a corresponding lid can be replaced with little effort in the event of damage without having to dismantle the linear actuator.
- the linear actuator is preferably provided with a mechanical, pneumatic or electric drive.
- the solution according to the invention can be used in a particularly advantageous manner for charging connection devices in passenger cars that are equipped with an electric drive system.
- Two charging connections are advantageously provided, one of which is intended for charging with alternating current and the other for charging with direct current.
- the cover is advantageously assigned to at least the charging connection, which enables charging with direct current. In its closed position, the cover serves as protection against weather conditions and also as a safety device to protect operators from electric shocks if the operator's limbs come close to the charging connection.
- the linear actuator can only rest on the cover at the front or can also be mechanically coupled to the cover.
- an electrically driven control device which is assigned to the linear actuator in order to drive the linear actuator in at least one direction of movement.
- the electrically driven control device enables extremely convenient and automated opening of the lid, preferably depending on corresponding specifications which are assigned to the control device.
- the linear actuator can also be operated to open the lid if charging is to take place with a type of current which requires the connection of a charging plug of a stationary charging station to the charging connection closed by the lid.
- the electrically driven control device is used at least in the direction of movement which causes the lid to be transferred from the closed position to the charging position.
- the electrically driven control device can also cause the lid to be returned from the charging position to the closed position.
- the lid can be returned from the charging position to the closed position by a return spring arrangement described in more detail below, so that the electrically driven driven control device only has to move the linear actuator in the direction of the opening position against the return force of the return spring arrangement.
- the linear actuator is designed as a thrust piston which is mounted in a housing of the loading trough and which is permanently in contact with the inside of the cover.
- the thrust piston advantageously protrudes through a passage in the housing of the loading trough from an inside to an outside of the loading trough in order to actuate the cover arranged on the outside.
- a corresponding linear guide for the thrust piston is therefore provided in a fixed position on the housing of the loading trough.
- control device has a rotary drive which is coupled to the thrust piston by means of a gear.
- the gear preferably has a linearly movable transmission element which mechanically interacts with the thrust piston.
- Drive rotations of the rotary drive are therefore converted into a linear movement of the thrust piston, either by the gear engaging the thrust piston directly or by the gear engaging a linearly movable transmission element which in turn mechanically interacts with the thrust piston.
- a threaded spindle or a rack is provided as the transmission element.
- a threaded spindle a linear movement in the form of a feed is generated by rotating the threaded spindle, either for the threaded spindle itself or, in the case of a stationary rotary bearing of the threaded spindle, by linear displacement of a worm arranged on the threaded spindle, which is coupled to the thrust piston.
- a rack With a rack, a pinion of the transmission engages the rack, which in turn is guided so as to be linearly movable.
- the transmission member is movably mounted orthogonally to the direction of movement of the thrust piston, and a mechanical deflection arrangement is provided which deflects a linear movement force of the transmission member to the thrust piston.
- the mechanical deflection arrangement advantageously has contact surfaces on the transmission member on the one hand and on the thrust piston on the other hand, which are aligned at an angle to the directions of movement of the transmission member and the thrust piston and which complement each other and are in sliding contact with each other.
- This embodiment uses the principle of the inclined plane to achieve the corresponding movement transfer of the linear movement of the transmission member to the orthogonal linear movement of the thrust piston.
- the contact surfaces are also referred to as guide surfaces.
- a return spring arrangement which acts on the lid in order to exert a permanent torque on the lid in the direction of the closed position.
- At least one torsion spring is preferably provided as the return spring arrangement, which is arranged coaxially to the pivot axis of the lid.
- the electrically driven control device is advantageously used only to actuate the linear actuator from the closed position towards the loading position. In the opposite direction, the control device is designed such that the linear actuator is pushed back into its starting position by the lid solely by the restoring force of the return spring arrangement. In this embodiment, the electrically driven control device can be in an idle position in the direction of movement from the loading position towards the closed position.

- Fig. 3 schematically shows a portion of the charging connection device according to Figs. 1 and 2, seen from an inner side and omitting a charging recess with the lid closed and
- Fig. 4 shows the functional arrangement according to Fig. 3 in a different perspective and with the lid pivoted into the loading position.
- a charging connection device 1 according to Fig. 1 to 4 has a charging trough 2, which is mounted in a manner not shown in the area of the outer body shell of a motor vehicle in a ready-to-use state.
- the charging trough 2 forms a dimensionally stable housing, advantageously made of plastic, which is connected to corresponding vehicle body parts of the vehicle body.
- the charging trough 2 can be covered on the outside by a trough cover 3, which is only shown schematically, wherein the trough cover 3 is in a In the closed position, the loading trough 2 is completely covered on the outside and is aligned flush with the outer skin of the adjacent vehicle body sections.
- the trough cover 3 is movably mounted on the vehicle side between the open position shown in Fig. 1 and a closed position covering the loading trough 2.
- the loading trough is movably mounted on the vehicle side between the open position shown in Fig. 1 and a closed position covering the loading trough 2.
- a first charging port 4 is a socket for alternating current and the charging port 5 below it in the vertical direction of the vehicle is provided with a direct current socket.
- Both charging ports 4, 5 are electrically connected to a battery system of an electric drive system of the motor vehicle.
- a charging plug from a stationary charging station is plugged into the respective charging port 4, 5 and thereby electrically contacted for charging.
- the corresponding charging plug is plugged into one charging port 4 or the other charging port 5.
- the charging connection 5, which is provided with a direct current socket and forms the lower charging connection in the illustration according to Fig. 2, is additionally assigned a cover 6, which closes the charging connection 5 when not in use according to Fig. 1.
- the cover 6 is pivotally mounted about a pivot axis S in the area of the
- the pivot axis S is positioned in the vertical direction of the vehicle below the charging connection 5 and is at least largely aligned in the longitudinal direction of the vehicle, assuming that the loading trough 2 is aligned in a plane essentially spanned by the vertical direction of the vehicle and the longitudinal direction of the vehicle.
- a pivot bearing which can be clearly seen in Figs. 3 and 4, is provided for mounting the cover 6 about the pivot axis S.
- the cover 6 is permanently subjected to torque in the direction of its closed position by a return spring arrangement 8, which is formed by two torsion springs.
- a linear actuator 7 in the form of a thrust piston is provided, which engages at a distance above the pivot axis S on an inner side of the lid 6 facing the loading connection 5 and is mounted orthogonally to the pivot axis S in a linearly movable manner in the housing formed by the loading trough 2.
- the housing of the loading trough 2 has for this purpose a linear guide (not shown in detail) for the linear actuator 7, which is fixed to the housing and which opens outwards in the transverse direction of the vehicle into a passage 9, the edge contour of which is matched to a cross section of the linear actuator 7.
- the linear actuator 7 is therefore arranged in the transverse direction of the vehicle between a the passage 9 of the loading trough 2, a rest position (Fig. 3) recessed into it and a functional position (Fig. 4) moved outwards in the transverse direction of the vehicle.
- the inside of the cover 6 has a stop cam 16, which is preferably formed in one piece and is in permanent contact with an end face of the linear actuator 7.
- the stop cam 16 forms a support for the cover 6 relative to the linear actuator 7.
- the stop cam 16 gradually slides downwards on the end face of the linear actuator 7 during a travel movement of the linear actuator 7 from the rest position to the functional position.
- the end face of the linear actuator 7, which is designed as a thrust piston, is provided with a run-on slope, as can be seen in Fig. 4.
- the stop cam 16 In the outwardly moved functional position, the stop cam 16 is positioned below an underside of the linear actuator 7, so that the linear actuator 7 has slightly overrun the stop cam 16 and thus forms a secure support for the stop cam 16 on the underside of the linear actuator 7.
- an electrically driven control device is provided, which is described in more detail below.
- the guide bevel 10 is part of a deflection arrangement that transmits a rotary force of an electric drive motor 15 of the control device to the linear actuator 7 by means of a gear.
- the gear has a rack and pinion drive with a rack 12 mounted in a linearly movable manner parallel to the pivot axis S, which forms a transmission element of the gear.
- the rack 12 has on its front side facing the guide bevel 10 a complementary along a parallel inclined plane, which rests against the guide bevel 10 of the linear actuator 7 and slides along the guide bevel 10 during a longitudinal displacement movement of the rack 12.
- the rack 12 is mounted in a linearly movable manner parallel to the pivot axis S by means of guide sections not shown in detail.
- the rack 12 has a laterally arranged toothing 13 which meshes with a spur toothing of a pinion 14 which is rotationally driven by the electric drive motor 15.
- the guide surfaces 10 and 11 form contact surfaces in the sense of the invention. All functional parts described are parts of the control device mentioned above.
- a threaded spindle is provided as a transmission element between the electric drive motor 15 and the linear actuator 7, which is driven by a drive pinion designed as a worm pinion, which can be positioned analogously to the pinion 14.
- the threaded spindle can also be driven via a differently designed gear in such a way that a feed for the threaded spindle is created, which exerts the thrust movement offset by 90° on the linear actuator 7 via a suitable deflection arrangement.
- the threaded spindle can be mounted in a stationary, rotatable manner and can linearly displace a worm mounted on the threaded spindle in a screw-movable manner, which has an inclined guide surface analogous to the deflection arrangement described above.
- the electrically driven control device and also the guide for the linear actuator 7 are designed in such a way that no self-locking occurs when the electric drive motor is switched off. It is therefore sufficient that the electric drive motor 15 is activated when the linear actuator 7 is moved from the rest position towards the functional position. The electric drive motor 15 remains activated as long as a corresponding charging plug is docked to the charging port 5. As soon as a charging process is completed and the charging plug is removed from the charging port 5, the electric drive motor 15 is deactivated, causing the gear with the pinion 14 and the rack 12 to idle, so that the restoring force of the restoring spring arrangement 8 can return the closing cover 6 to the closed position.
