Description

The invention relates to a charging interface of an electrically driven or drivable motor vehicle, in which a DC plug-in face is protected by a cover from reaching in or becoming dirty, the cover being able to be moved from a covering position to a rest position and back by means of an actuator on a movement path, which at least partially includes a rotation of the cover. The invention also relates to a method for controlling such a charging interface and a vehicle with this.

Electric vehicles have a charging interface through which electrical energy can be supplied to the vehicle. This charging interface often has a connection for so-called AC charging, in which the vehicle battery is charged with an alternating current (AC) and a connection for so-called direct current charging or DC charging, in which the vehicle battery is charged with a direct current (English: Direct current, DC) is charged. The connections can be designed, for example, as a CCS socket (Combined Charging System, CCS) with a Combo 1 or Combo 2 socket, but other charging systems such as Chademo 2 or Chademo 3 or ChaoJi can each be equipped with an AC -Connection can be combined.

The standard requires that the DC connection is covered so that a user cannot reach into it and that the contacts are protected from ingress of dirt and/or moisture and the resulting corrosion. Such a cover usually requires manual removal by the user before charging begins, so such a charging interface is not suitable for automatic charging or a charging process carried out by a robot.

Individual solutions are disclosed in the prior art, such as how a cover flap of a DC connection can be opened using a spring mechanism ( DE 10 2017 222 397 A1 ). The movement of the cover flap is linked there to the movement of the loading flap. In addition, from the DE 10 2017 222 397 A1 a charging connection device is known in which a DC cover is opened by means of various lever elements when a charging plug is inserted into the charging socket.

These solutions always require a mechanical coupling of the DC connection cover with the opening mechanism of the charging flap. This requires adjustments to this opening mechanism and integration of the mechanics for opening the DC cover.

It would therefore be desirable to find a solution for opening the DC cover that can be designed independently, i.e. without interfering with the opening mechanism of the loading flap, and is robust and suitable for everyday use. It should be technically simple and cost-effective to implement. The object of the invention is therefore to find and propose such a solution.

The object of the invention is achieved with a charging interface according to claim 1, a method for controlling a charging interface according to claim 7 and a vehicle according to claim 10. Further preferred embodiments of the invention result from the remaining features mentioned in the subclaims.

According to the invention, a charging interface of an electrically driven or drivable motor vehicle is provided, which is formed with a charging socket with an AC plug face and a DC plug face, a charging flap that can be pivoted by an electric motor and a cover for the DC charging face, the cover for the DC charging face is to be moved by means of an actuator between a covering position and a rest position and the cover for the DC charging face is mounted and held in such a way that the movement path between the covering position and the rest position has, at least in sections, a rotation of this cover.

A charging interface is therefore provided for an electrically driven or drivable vehicle. This can be a purely electrically powered or propellable vehicle, but also a so-called hybrid vehicle, in which an electric drive is combined with another type of drive. The charging interface is formed with a charging socket that has an AC connector face and a DC connector face. There is therefore one connection each for AC charging and DC charging. The connections can be in the form of a CCS socket (Combined Charging System), but also in the form of a combination of a Chademo socket with an AC connection or a ChaoJi connection in combination with an AC connection.

The charging interface is closed to the environment with a charging flap that can be opened and closed by an electric motor. For this purpose, for example, an actuator can be designed and arranged in such a way that it opens the loading flap for loading and then closes it. Furthermore, the charging interface can, as in the stand known in the art, and according to the invention is further developed into an electrically driven cover for the DC charging face.

The electrically driven cover for the DC charging face can be designed in various ways, as long as it covers, seals and protects the DC charging face safely and reliably in accordance with the normative specifications. Preferably, the cover can be designed as a plug that can be moved as explained below. But a design in the form of a plate or disk or the like is also within the scope of the invention.

To move the cover, the charging interface has an actuator that can move the cover from a covering position to a rest position and back. This is preferably an electric motor actuator. The cover position is the position where the DC charging face is covered and protected from environmental influences. The rest position is the position where the cover is removed from the DC charging face so that it can be used for charging. The cover is moved away from the covering position so that it does not hinder the insertion of the charging plug into the charging socket.

According to the invention, the cover is mounted and held in such a way that it can be moved from the covering position to the rest position and back by means of the actuator. The movement of the cover should have a rotation at least in sections during the change of position. As soon as the actuator begins a change of position of the cover, it moves along a movement path that describes the course of the movement of the cover during the change of position. This movement path should run in such a way that the cover is rotated at least in certain areas and is thus guided on the way to the rest position in such a way that it does not hinder the charging process and can be held securely at the same time. Other directions of movement along the movement path, for example translational movement sections, can also be provided and implemented.

The cover can be held and stored in a variety of ways, some exemplary embodiments of which are described in detail below. When the cover is returned to the covering position, the rotation is (also) returned so that the covering position can be reached.

By designing the charging interface with a cover that is at least partially rotated from the covering position to the rest position by means of an actuator, a simple and cost-effective cover for the DC connection can be realized, which also takes up very little installation space. It can be implemented independently of the opening of the loading flap, so that the opening mechanism provided does not necessarily have to be changed. In addition, the normative requirements are also met.

The proposed solution is robust and suitable for everyday use. In this way, the charging process can be made more convenient for a user because he no longer has to manually remove or attach the cover. The main advantage, however, is that the automatic removal and attachment of the DC cover makes an automatic or robot-carried charging process possible, because in this way the charging interface is opened for the charging process and the DC plug face is exposed for the charging process without user intervention.

According to a first embodiment of the charging interface according to the invention, the cover for the DC charging face is held on two opposite sides on the DC charging face and / or near the DC charging face by at least one rotating arm, with a rotating arm on one side and a rotating arm on the on the other side have a common axis of rotation and the rotating arms are to be rotated about the common axis of rotation by means of the actuator.

Accordingly, the cover for the DC charging face should be held and moved using corresponding rotating arms. A rotating arm should be understood as a component that is rotatably mounted at one end in the area of the charging interface, namely on the DC charging face and/or in its vicinity. The exact position and size of such a rotating arm results from the size of the cover, the size of the DC connector face and the available installation space, i.e. from the geometric conditions on the vehicle in the area of the charging interface. The arrangement can take place on the DC charging connection, on the frame of the charging interface, in the charging trough in which the connections are arranged or the like, provided that the movement of the cover by means of the rotating arms can reach a rest position that is free of obstacles for the charging process. The cover is held at the free end of the rotating arm.

As already mentioned, at least one rotating arm should be provided on two opposite sides of the DC charging face, with two opposing rotating arms corresponding to each other and having a common axis of rotation. The corresponding rotating arms rotate around the same axis of rotation and hold the cover. The sides of the DC charging face mean the side areas along the circumference of the DC charging face or the DC connection. Depending on the specific design and orientation of the charging ports, this can include the left and right sides, but also the top and bottom.

The movement of the cover is now achieved by the actuator rotating the at least two rotating arms, i.e. the at least one rotating arm on each side of the plug-in face, and thus moving the cover from the rest position to the covering position and vice versa. If only one pair of rotating arms is provided, the resulting movement path corresponds to a circular path. The cover for the DC plug face is therefore rotated from the covering position to the rest position and the return to the covering position also follows a rotational movement.

Several pairs of rotating arms can also be provided, each of which has a common pivot point, whose axes of rotation are therefore identical. This allows the cover to hold better.

Preferably, the cover for the DC charging face is held on two opposite sides on the DC charging face and/or near the DC charging face by two rotating arms, with a rotating arm on one side and a rotating arm on the other side each having a common axis of rotation, so that there are two axes of rotation, these axes of rotation being aligned essentially parallel to one another and the rotation of the rotating arms by means of the actuator causes a movement path of the cover that corresponds to a curved path and in which the cover is in the rest position about an axis parallel to the two axes of rotation is rotated.

Two rotating arms are therefore provided on each side of the DC charging face, two of which lie opposite one another and form a common axis of rotation, the resulting two axes of rotation being essentially parallel to one another. The axes of rotation are therefore spaced apart from one another. The exact position can be determined depending on the available installation space, the size of the individual elements and other geometric boundary conditions. The actuator of the charging interface now has a rotating effect on the two pairs of rotating arms and the fixation of the two pairs of rotating arms and their coupling with the cover results in a curved path which is composed, among other things, of circular path sections and along which the cover moves from the covering position to the rest position can be moved in reverse.

When the cover reaches its rest position, it has experienced, as a result or in its final orientation, a rotation about an axis of rotation that runs parallel to that of the rotating arms.

In another embodiment of the invention, the cover for the DC charging face is designed with a rod-shaped rotating element, which is arranged or formed perpendicular to a plane of the cover surface and connects it to the actuator, the rod-shaped rotating element and thus also the cover by means of the actuator is to be moved along the longitudinal axis of the rod-shaped rotating element in a direction perpendicular to the DC charging face and is to be rotated about the longitudinal axis of the rotating element

The cover is further developed in such a way that it additionally has a rod-shaped rotating element. This extends in its longitudinal axis perpendicular to the cover surface of the cover and thus also perpendicular to the plane of the plug-in face of the DC cover. The rod-shaped rotation element can be hollow on the inside, i.e. a hollow body or designed as a solid body. It can be arranged on the cover, i.e. attached or formed on it. What is important is that it connects the actual cover to the actuator.

During its operation, the actuator acts on the rod-shaped rotating element in such a way that it, and thus also the cover as such, is moved in a direction perpendicular to the DC charging face, by which is meant away from it or towards it, and also is rotated about the longitudinal axis of the rotation element. Both movements, i.e. rotating around the longitudinal axis of the rotating element and the movement in the direction of the longitudinal axis of the rotating element, can take place simultaneously or one after the other. In order to open the DC cover, for example, the cover could first be moved outwards from the covering position, i.e. away from the DC plug-in face, and then rotated clockwise or counterclockwise around the longitudinal axis of the rotation element into the rest position until it does not protrudes more into the area of the charging plug to be inserted. To cover the DC plug face again, rotate backwards and then move towards the DC plug face. As already indicated, the respective types of movement can also take place at the same time or at least partially at the same time with a time offset.

How far the rotation element and thus the entire cover has to be moved in the longitudinal axis of the rotation element depends largely on how deep inside the loading trough the DC plug-in face is arranged and whether there is enough space within the charging trough to rotate the cover there or whether it first has to be moved to an area outside the charging trough, i.e. outwards, in order to then rotate there. This also results in a possibly necessary temporal staggering of the types of movement, so that when approaching the rest position, for example, the cover is first moved outwards until it can be rotated safely and without damage, i.e. does not collide with other components, and then the rotation begins , while the outward movement can continue until it reaches its final position. When approaching the cover position, a rotation can therefore first take place, which can then be combined with a movement of the cover towards the DC plug face and then takes place without rotation.

The movement of the rotation element can be achieved, for example, by a set screw starting from the actuator engaging in the rotation element or otherwise interacting with it, so that the movement of the actuator can be transmitted to the rotation element and thus the cover.

In order to limit both the rotation of the rotation element and the movement along its longitudinal axis, a stop or several stops on the rotation element prove to be useful, which prevent over-rotation or excessive movement in the longitudinal axis of the rotation element in any direction.

It is preferably provided that the cover rotates in a direction in which the rest position is arranged in the area of the loading trough and the loading trough has a niche in the area of this rest position. For this purpose, the loading trough must be designed in such a way that there is an area of free installation space within the loading trough, i.e. a niche whose size corresponds to the size of the cover when it is moved into the rest position. For example, if the rod-shaped rotating element is arranged with a pivot point to the left below the DC plug-in face, according to this embodiment, the rotation of the rotating element with the cover would run counterclockwise in the direction of a niche that would be provided to the left of the DC plug-in face. This would have the advantage that a smaller stroke, i.e. a shorter movement of the cover on the rotating element in the direction of its longitudinal axis, would have to take place and the risk of scratching the paint of the vehicle would also be avoided if the cover were pivoted outwards.

In the cold season it can happen that moisture penetrates into the area of the charging trough and the cover freezes on the DC connector face. Then the cover of the DC connector face could not be loosened and moved away from it. In fact, it can even cause damage. Therefore, in a further embodiment it is provided that the cover is designed with a [heating device] _[SW1], regardless of the movement principle. In this way, energy can be supplied through or along the components that hold and store the cover, which supplies the heating device in the cover. If the charging interface is to be opened, the cover is heated, the ice is melted and the cover can be opened without damage.

With the charging interface explained above, a compact and everyday solution is proposed as to how a cover for a DC connection can be realized with a small space requirement and technically simple means. Such a charging interface for an electrically driven or drivable motor vehicle can preferably be controlled using a method that has at least the following steps:

• • Selecting or triggering a charging process,
• • Opening the electric motor-driven loading flap,
• • Opening the cover of the DC charging face,
• • after charging, close the cover of the DC charging face, and
• • Closing the electric motor-driven loading flap.

A charging process can be selected by a user in the vehicle, for example via the center display and the user interface provided with it. As an alternative to the selection in the vehicle via a user interface, a switching element, such as a button in or on the vehicle, can also be provided, with which a charging process can be initiated. Finally, a charging process can be triggered automatically by registering a specified trigger. This can, for example, be done depending on the location: based on current position data such as GPS data and available navigation and map data, it can be recorded whether the vehicle is at a charging station and the charging process can then be started or whether it is positioned near the home charging facility, for example. Alternatively, such a trigger can be a Car2X communication (English for communication between vehicle and its surroundings), which occurs, for example, between a charging column or charging station and a vehicle when it is parked next to it. This kind of Car2X communication is particularly suitable also good if automated charging or robot charging is to take place.

Once the charging process has been triggered or selected, the charging flap, which can be swiveled by an electric motor, is opened and then the cover of the DC charging face. The opening takes place according to the structural conditions and specific design of the cover and its holder or storage.

The charging plug can now be inserted into the charging interface and the vehicle batteries can be charged in a known and usual manner. As already indicated, this can be done manually or automatically and in particular using a charging robot. After charging is complete, the charging plug is removed manually or automatically. The DC cover is then closed, followed by the charging flap, which can be swiveled by an electric motor.

In order to implement the method, the various selection devices and/or detection devices must interact with a control device which, from the transmitted information, provides the necessary control signals for controlling the actuator of the loading flap and that of the cover, so that they activate the loading flap or the DC cover move in the desired way.

The method for controlling the charging interface can be further developed in such a way that an occupancy state of the DC connector face is detected and, if it is not occupied, the DC cover is closed during the charging process. So if the charging interface and the DC connection are open and the DC connection is not used because only alternating current is being charged, this negative occupancy state automatically triggers the closing of the DC cover in order to protect the contacts from contamination before a user intervenes , moisture and the like. The detection of the occupancy state is known per se and will therefore not be discussed further here.

In individual embodiments of the charging interface, the situation may arise where the charging plug prevents the DC cover from closing during pure AC charging. In such cases, automatic closing cannot occur. At this point, two solutions can be suggested: opening the DC cover could be triggered manually in such configurations, rather than automatically, as stated above in the method for controlling the charging interface. Alternatively, the DC cover is not closed during AC charging.

Finally, a vehicle is claimed which has a charging interface according to the invention and is in particular controlled using a method as disclosed above.

The charging interface according to the invention is easy to implement, compact and suitable for everyday use. Since it opens automatically, it is also suitable for automatic loading, especially using robots. When charging manually, it increases the convenience for the user because he does not have to operate the charging flap and the DC cover manually, which means he only has to carry out a few steps to charge the vehicle and, in the worst case scenario, he no longer has to dirty his hands. By designing the charging interface with an actuator that moves the cover for the DC connector face, accidental or intentional manual closing of the DC cover or charging flap can be prevented, since this design blocks unauthorized movement of the elements and thus effectively prevents them .

The various embodiments of the invention mentioned in this application can be advantageously combined with one another, unless stated otherwise in individual cases.

The invention is explained below in exemplary embodiments using the associated drawings. Show it:

• 2 a cut through the charging interface 1 ,
• 3 the movement of the cover 1 ,
• 4 an alternative embodiment of the charging interface according to the invention,

1 shows a first exemplary embodiment of the charging interface 10 according to the invention 1a the cover 20 for the DC connection 16 with DC plug face closed, i.e. in the cover position 22, while 1b and 1c shows the cover 20 in the rest position 24 from different angles.

The charging interface 10 is formed with a charging flap 12, which is moved by an electric motor, a charging trough 11 and a charging socket 13, which in turn is formed with an AC connection 14 with an AC plug face and a DC connection 16 with a DC plug face. The DC connector face 16 is in 1a covered by the cover 20 in its covering position 22, so that the normative requirements are met. In 1a a section AA is also marked, which is shown below 2 is shown.

The cover 20 for the DC charging face 16 is designed according to 1 held on both sides by two corresponding pairs of rotating arms 30, each of which has a common axis of rotation 32, these axes of rotation 32 being spaced apart from one another and aligned parallel to one another. By means of an actuator 26 (for the sake of clarity only in 1b shown), the two rotating arms 30 are rotated so that they remove the cover 20 from the plug face of the DC connection 16 and move it into the rest position 24. The actuator 26 does not have to drive both rotary arms 30, provided that the non-driven one is rotatably mounted and is moved via the cover 20 by the mechanical coupling. This creates a so-called cam mechanism with which the cover 20 can be moved.

Out of 2 The movement path 18 can be seen, which corresponds to a curved path 34 in this embodiment. Shows for illustrative purposes 2 the cover 20 in a simplified representation in the covering position 22 and in the rest position 24, as well as the position of the rotating arms 30 before the movement (designated as 30.1) and after the movement (designated as 30.2). The direction of movement of the rotating arms 30.1, 30.2 about their axes of rotation 32 is indicated by the arrows 31.

The individual intermediate stages in the movement path 18, 34 are in the movement sequence of 3 shown. This is how the movement begins 3a in the covering position 22 of the cover 20 on the charging face of the DC connection 16. The actuator (not shown here) engages the lower rotating arm 30 and rotates it. The upper rotating arm 30 rotates about its axis of rotation 32. The cover 20 is now moved away from the DC connection 16 and downwards ( 3b until 3e) , whereby it is also rotated due to the holder by means of the rotating arms 30. In 3f It can be seen that the cover has undergone a rotation of over 90 ° and is now rotated in its final position about an axis of rotation that is parallel to the axes of rotation 32 of the rotating arms 30.

After reaching the rest position 24 in 3e the charging plug can be 50 as in 3f shown, introduced and the vehicle loaded. If only alternating current is charged, this is recognized based on the occupancy status of the DC connection 16 and the DC cover 20 is closed during AC charging.

After charging has been completed and the charging plug 50 has been removed, the actuator 26 rotates the rotary arms 30 back and thus moves the cover 20 back into its covering position 22. The loading flap 12 is then closed. Since the cover 20 is opened and closed on the DC charging face by means of the actuator 26 and no manual intervention is necessary, this charging interface 10 is also suitable for automatic charging processes, in particular with the help of robots.

4 shows an alternative embodiment of the charging interface 10 according to the invention, in which the cover 20 is designed with a rod-shaped rotating element 40. The remaining design of the charging interface 10 remains the same.

4a shows the cover 20 in the covering position 22 and 4b in the rest position 24. A detailed representation in the area of the rod-shaped rotation element 40 as well as a sequence of movements is in 5 shown. This becomes from the 5a and 5b clear that the rod-shaped rotation element 40 is aligned and designed essentially perpendicular to the actual covering surface of the cover 20. It has a longitudinal axis 42 and a stop 46. By means of the actuator 26, the rotation element 40 is now moved outwards along its longitudinal axis 42 in relation to the installation situation ( 5c ), this movement being caused by the stop 46, as in 5d shown, is limited. The actuator 26 can transmit its movement by means of a threaded rod to the rod-shaped rotating element 40, which is designed here as a hollow body.

If the cover 20 is moved far enough out of the loading trough 11 that it does not collide with the body of the vehicle during rotation, the rotational movement 28 of the cover 20 begins about the longitudinal axis 42 of the rod-shaped rotating element 42 ( 5e and 5f) until the rest position 24 is reached, in which a charging plug is no longer hindered when inserted into the charging interface 10.

In order to cover the DC connection 16 again, the cover 20 first rotates back again and is then moved in the direction of the DC plug face. The one already related to 5d The stop 46 mentioned ensures that the reverse rotation does not lead to overwinding. If the cover 20 reaches the covering position 22, the loading flap 12 can also be closed.

In order to solve or prevent the DC cover from freezing in winter, the cover is ckung 20 is formed with a heating device (not shown), the electrical supply lines of which can lead along the rod-shaped rotating element 40 or through it.

6 in turn shows an alternative rest position 24 for a cover according to 4 . Here the loading trough 11 is formed with a niche 44. In this case, the cover 20 is rotated counterclockwise and can assume its rest position 24 in the area of the niche 44. Optionally, in the end position it can also be moved slightly towards the loading trough 11 so that it does not protrude. The advantage of this embodiment is that the movement in the direction of the longitudinal axis 42 of the rotation element 40 can be shorter than in the embodiment 4 and the rest position 24 can therefore be reached more quickly. In addition, scratching of the paint of the vehicle can be avoided by the cover 20 protruding above it.

Regardless of how the cover 20 is designed and how it moves between the cover position 22 and the rest position 24, its movement, like that of the loading flap 12, is controlled by a control device (not shown). For this purpose, the opening of the charging interface 10 can be initiated manually by a vehicle user using a button on the vehicle, in particular near or on the charging interface 10 or the like, but alternatively also via a suitable interface in the vehicle, such as the center display. The opening of the charging interface 10 can also take place when the vehicle reaches a known charging location, which is defined using GPS coordinates, or it can be initiated by communication between the vehicle and a charging infrastructure.
