Abstract

The aim of the invention is to provide a simplified production and operation of a charge socket (5) for a motor vehicle (1), comprising a first current connection (15), a second current connection (20), and a contact protection means (25) which selectively covers the first current connection (15) or the second current connection (20) in a cover position or does not cover either current connection in an open position. This is achieved in that the contact protection means (25) is completely removed from the charge socket (5) when transitioning from the cover position to the open position or vice versa.

Description

Charging socket for a motor vehicle and motor vehicle equipped therewith

The present invention relates to a charging socket for a motor vehicle according to claim 1 and a motor vehicle equipped therewith according to claim 11.

DE 102017222503 A1 discloses a charging socket for an electrically drivable motor vehicle, in which a first power connection and a second power connection are provided on a charging socket holder. When the charging socket is in a non-use position, the first power connection and the second power connection are covered by a contact protection means. In a position of use, the contact protection means is manually removed from the two power connections and held in a receptacle located in a charging flap. Consequently, both power connections are exposed in the position of use, which is not always desirable.

DE 10 2011 014 462 A1 and DE 10 2021 000 307 A1, on the other hand, each disclose a contact protection means by means of which one of the two power connections is covered while the other power connection is exposed. For this purpose, the contact protection means is designed to be movable in a displacement direction by means of a mechanism via the two power connections. Such a mechanism has the disadvantage, however, that it has a comparatively complex design and is associated with high costs.

It is the object of the present invention to overcome the disadvantages mentioned above.

This problem is solved by a charging socket according to patent claim 1 . Specifically, the above object is achieved by a charging socket for a motor vehicle that has a first Power connection and a second power connection, as well as a contact protection means, which optionally covers the first power connection or the second power connection in a covered position or does not cover it in an open position, and is characterized in that the contact protection means during the transition from the covered position to the open position or vice versa, ie from the covering position to the open position, is completely removed from the charging socket. In other words, the charging socket according to the invention is set up in such a way that the contact protection means covers one of the power connections in a covering position, while the other power connection is in the open position, ie is not covered by the contact protection means. If, on the other hand, it is desired that the latter power connection is covered by the contact protection means, ie should be in a covering position, the contact protection means is completely removed from the former power connection and moved to the power connection to be covered and fastened. The movement itself is done manually. In this respect, one could also speak of a system consisting of a charging socket, which is provided with at least two power connections, and a contact protection device. This advantageously creates a charging socket that can be easily manufactured and operated, in particular covered.

According to a preferred embodiment, the charging socket according to the invention is characterized in that the contact protection means is fastened in its covering position in a non-positive and/or positive and/or frictional manner with at least one fastening means located on the charging socket and/or the first power connection and/or the second power connection . This creates a particularly simple structure for the charging socket, in which the contact protection means can be conveniently and reliably attached in the covering position.

This applies all the more if the fastening means has at least one first receiving means located around the first power connection and at least one second receiving means located around the second power connection, in which the contact protection means is received in its covering position.

According to a further preferred embodiment, the charging socket according to the invention is characterized in that the first receiving means and the second receiving means are formed in one piece. This advantageously facilitates in particular the assembly of the receiving means, so that the production of the charging socket is simplified overall.

According to an additional preferred embodiment, it is provided that the contact protection means is at least partially made of an elastic material and/or metastable material. This not only makes it easy to manufacture the contact protection means, but also allows the same to be held in the covering position in a particularly reliable manner.

A particularly convenient operation of the charging socket according to the invention is advantageously achieved in that the contact protection means has a handle. The handle can be designed in particular as a step, projection, recess, handle, eyelet and the like on the top or an edge area of the contact protection means, so that it can be easily reached and gripped by a user.

Provision is advantageously made for the contact protection means to have a protruding projection which is set up to be accommodated in the covering position in the charging socket and/or the first power connection and/or the second power connection. This creates a reliable attachment of the contact protection means with a simple technical means.

Alternatively or cumulatively, according to a preferred embodiment, it can be provided that the contact protection means has at least one movable section which is set up to interact in the covering position with at least part of the covered power connection in a non-positive, positive and/or frictional manner.

A particularly reliable mounting with convenient operation of the charging socket according to the invention is achieved in an advantageous manner if the fastening means at least partially has a collar section spaced apart from the charging socket, in which an edge section of the contact protection means is accommodated in its covering position. Alternatively or cumulatively, it can be provided that at least part of the contact protection means is designed as a magnet and/or magnetic component or as a magnetizable part, and the part of the charging sockets that corresponds to this in the covering position and/or part of the fastening means is designed as a magnet or as a magnet magnetic component or, if the contact protection means is designed as a magnetizable part, as a magnet and/or magnetic component. This advantageously creates a device that can be produced inexpensively and functions reliably, and that can also be operated easily and intuitively.

It goes without saying that any suitable material or any suitable combination of materials can be selected with regard to a magnetically locked connection. The magnet provided or the magnetic material provided is made of a soft magnetic material, in particular an alloy based on iron, nickel and cobalt or as soft ferrite (NiZn, MnZn), or a hard magnetic material, in particular NdFeB or an AlNiCo alloy , educated.

In particular, the following conditions can exist:

If the charging sockets are made of a magnetizable material, in particular a metal or a metal alloy, completely or at discrete points or has such a material at discrete points, the contact protection means can be provided or formed with a magnetic material completely or at discrete points to achieve the desired magnetic closure in the masking position.

If the charging socket is made of a magnetic material completely or at discrete points or has a magnetic material at discrete points, the contact protection means can be provided or formed with a magnetizable material completely or at discrete points in order to achieve the desired magnetic closure in the covered position .

If the charging socket is made of a magnetic material completely or at discrete points or has a magnetic material at discrete points, then the contact protection means can be provided or formed with a magnetic material completely or at discrete points in order to achieve the desired magnetic closure in the covering position. It should be noted here that the respective magnetic points or poles that are adjacent in the covering position are designed in such a way that they attract one another.

The stated object is also achieved by a motor vehicle that has at least one charging socket of the type disclosed above. The advantages presented apply adequately.

A detailed, non-prejudicing, in particular limiting, description of exemplary embodiments of the present invention is given below with reference to the attached figures, which are not to scale:

7A and 7B show an alternative charging socket with a contact protection means located in different positions.

FIG. 1 shows part of a motor vehicle 1 according to the invention, shown symbolically, in which a charging socket 5 is installed. The charging socket 5 can be located at any suitable location, for example in the side area, the front area or the rear area of the motor vehicle 1 . A charging socket holder 10 is provided on the charging socket 5, which has a first power connection 15 and a second power connection 20 located above it, each with different plug faces, as is symbolically represented by the different symbols for the two power connections 15, 20. It should be noted that the charging socket 5, like the charging socket holder 10, can be designed in one piece or in several pieces.

The second power connection 20 is covered by means of a contact protection means 25, which is symbolized by the dashed line of the power connection 20. The contact protection means 25 is thus in a covering position. Since the contact protection means 25 is in an open position in relation to the first power connection 15 , a charging plug (not shown here) can be connected to the first power connection 15 alone. Consequently, the contact protection means 25 is in an open position in relation to the first power connection 15 . The contact protection means 25 has a covering body 30 which bears against the charging socket holder 10 with its surface facing the charging socket 5 and covers the surface area formed by the second power connection 20 within a virtual plane spanned by the charging socket holder 10 . A handle 35 designed as a handle extends further from the plane of the paper in Figure 1A in the direction of the viewer. Finally, the contact protection means 25, in particular the covering body 30, comprises a peripheral side edge 40 and the charging socket 5 each has an edge 45 complementary thereto in the vicinity of the first Power connection 15 or second power connection 20.

Using the handle 35, the contact protection means 25 can be removed manually from the second power connection 20 in a simple manner, as is symbolized by the arrow I. In this case, both the first power connection 15 and the second power connection 20 are in an open position, as can be seen in FIG. 1B. The contact protection means 25 is thus completely removed from the charging socket 5.

The contact protection means 25 can then be fitted over the first power connection 15, as indicated by the arrow II in FIG.

For the purpose of a simple and reliable attachment or removal of the contact protection means 25, there are a number of force-fitting and/or form-fitting and/or friction-fitting means.

As can be seen from FIG. 2, which shows a charging socket 5 in a simplified sectional view from the side, the contact protection means 25 can be wedge-shaped on the outside. If, as symbolized by the arrow IV, it is to assume its covering position, it is moved in the direction of the charging socket 5 and comes to rest completely against a complementary edge 45 of the charging socket 5 with its peripheral side edge 40 . The geometric relationships of the contact protection means 25 and the edge 40 are selected such that there is a press fit, so that the contact protection means 25 located above the first power connection 15 or second power connection 20 together with the edge 45 seals completely. It goes without saying that the side edge 40 and the edge 45 complementary thereto can also have a different geometric shape. It is thus possible, in particular, for the latter not to be inclined in relation to a virtual plane spanned by the covering body 30, but instead to be straight.

FIG. 3A shows a further embodiment of a motor vehicle 1 according to the invention with an alternative charging socket 5 according to the invention, which is constructed in principle like the charging socket shown in FIG. 1B. However, according to the embodiment shown in Fig. 3A, the charging socket 5 also has two spaced-apart first receptacles 50 or second receptacles 55 adjacent to the first power connection 15 or the second power connection 20, in which suitable projections 60 protruding from the contact protection means 25 positively and/or non-positively and/or frictionally engaged in order to hold the contact protection means 25 securely on the charging socket 5 in the covering position. If, for example, the contact protection means 25 designed in this way is fastened over the second power connection 20, as is symbolized by the arrow V, the two protruding projections 60 engage in the respective second receptacles 55 and are mounted there firmly, but detachably. The same also applies to the side edge 40 or the edge 45, as has already been shown with reference to the previous figures.

For the purpose of further improved sealing, the peripheral edge 40 is provided with collar-shaped sealing means 65 extending in the direction of the protruding projections 60 . This can be seen particularly well in FIG. 3B, which shows a side view of the contact protection means 25 shown in FIG. 3A. As can be seen, the ends of the protruding projections 60 facing away from the covering body 30 are wedge-shaped, so that in the covering position they engage behind the surface of the covering body 30 facing the first electrical connection 15 or the second electrical connection 20 .

It should be noted that the number of the first shots 50, the second shots 55 and the protruding projections 60 taking into account the relevant technical and commercial boundary conditions, such as the simplicity and reliability of the attachment or detachment of the contact protection means 25 on or from the charging socket 5 and the cost of manufacturing the same, can be chosen freely. It is thus possible to provide only a single protruding projection 60, as can be seen in FIG. 3C. This is positioned essentially in the center of the cover body 30 and has a receiving space 70 open on one side at its end opposite the handle.

The contact protection means 25 shown in FIG. 3C can be used in the charging socket 5 shown in FIG. 3D. This is known per se and includes a first power connection 15 for direct current, which has a first plug receptacle 75 with a first ground conductor 80 . Furthermore, the charging socket 5 includes a second power connection 20 for alternating current, which has a second plug receptacle 85 with a second earth conductor 90 . The contact protection means 25 of FIG. 3C assumes the covering position with respect to the first power terminal 15 by inserting the protruding projection 60 into the first connector receptacle 75 with the first ground conductor 80 being received in the receptacle space 70 . When changing position, the contact protection means 25 of FIG. 3C assumes the covering position with respect to the second power connection 20 by inserting the protruding projection 60 into the second connector receptacle 85 , with the second earth conductor 90 being received in the receptacle space 70 .

4A to 4G show a further alternative embodiment of a charging socket 5 in a simplified side view in section. A collar section 95 is attached to the charging socket 5 around the first power connection 15 . The contact protection means 25 includes a cover body 30 with a handle 35 and is made of a metastable material. For the purpose of covering the first power connection 15, the contact protection means 25, which is essentially bell-shaped when viewed from the side, is placed over the first power connection and between the surface area formed by the collar section 95, as symbolized by the arrow VI in FIG. 4A. A pressure is then exerted on the handle 35 in the direction of the first power connection 15, as is symbolized by the arrow VII in FIG. 4B. The outer sections of the covering body 30 extend into the collar section 95. By continuing to exert pressure (see arrow VIII), the covering body 30 is finally overstretched and in the collar section 95 positively, non-positively and/or fixed by friction, as can be seen in FIG. 4C. By pulling on the handle 35 in the opposite direction of the arrows VI to VIII shown in FIGS. 4A to 4C, the contact protection means 25 can be removed from the first power connection 15 again.

The relationships presented above also apply, even if this is not shown in FIGS.

A further alternative embodiment of the charging socket 5 according to the invention is shown in FIG. 5A in a simplified side view in section. Specifically, the first power connection 15 is shown with the first plug receptacle 75 already shown, with the first ground conductor 80 not being shown for reasons of clarity. The contact protection means 25 has a multi-part structure, the side wall 100 of which rests on the charging socket 5 and surrounds the first power connection 15 . On the side of the contact protection means 25 facing away from the charging socket 5 there is a flexible, cover-like closing element 105 which can be moved or pushed in whole or in part in the direction of the charging socket 5 by means of a handle 35, as symbolized by the arrow IX. Between the closing element 105 and the charging socket 5 there is a stiffening means 110 which is aligned parallel to the closing element 105 and to which an expansion body 115 is attached at one end. While a shoulder section 120 spaced apart from the expansion body 115 rests against the top of the charging socket 5, the expansion body 115 extends at the other end into the plug receptacle 75 and rests against it. A central opening 125 extends the entire length of the stiffener 110 and is aligned with an opening 130 of the stiffener 110 . The expanding means 140 is attached at one end to the closing element 105 or is formed in one piece with it. At its opposite end, the expansion means 140 comprises a substantially wedge-shaped expansion section 145 which, according to the illustration in FIG. 5A, is in a state in which the contact protection means 25 is not attached to the charging socket 25. Rather, for the purpose of attachment, it is necessary to move the handle 35 in the direction of arrow IX. Here, the expanding means 140 moves in the same direction and the wedge-shaped end section 135 of the expanding means 140 presses the section of the expansion body 115 located in the first plug receptacle 75 against the inner wall 150 thereof, as a result of which a non-positive, positive or frictional connection is generated between them, by means of which the contact protection means 25 is attached to the charging socket 5. In order to release the contact protection means 25 again, it is only necessary to move the expanding means 140 in the opposite direction of the arrow IX.

FIG. 5B shows an embodiment of a charging socket 5 with contact protection means 25 which is an alternative to the embodiment shown in FIG. 5A. The charging socket 5 is designed in accordance with the exemplary embodiment shown in FIG. 5A. To avoid repetition, reference is made to the figure mentioned.

The contact protection means 25 in FIG. 5B has a multi-part structure, the side wall 100 of which surrounds the first power connection 15 and rests on the charging socket 5 . On the side of the contact protection means 25 facing away from the charging socket 5 there is a flexible, cover-like closing element 105 which can be moved or pushed in whole or in part in the direction of the charging socket 5 by means of a handle 35, as symbolized by the arrow X. Between the terminating element 105 and the charging socket 5 there is a stiffening means 110 which is aligned parallel to the terminating element 105 and to which a substantially bowl-shaped contraction body 155 made of an elastic material is attached by means of webs 160 at one end. The contraction body 155 overlaps the end of the first plug receptacle 75 facing the stiffening means 110 and rests against a part of its outer surface 165 . A compression means 170 bears against part of the outer surface of the contraction body 155, which is mechanically operatively connected to the handle 35 or the closing element 105 by means of a rod 175 and is translationally movable relative to the webs 160 due to openings in the compression means 170, which are not shown here. The rod 175 can be moved in translation through an opening 130 located in the stiffening means 110 . The compression means 170 is stiffer than the contraction body 155 and is made of hard plastic or metal, for example.

As shown in FIG. 5B , the compression means 170 is in a state in which the contact protection means 25 is not attached to the charging socket 25 . Rather, for the purpose of attachment, it is necessary to move the handle 35 in the direction of the arrow to move X. Here, the compression means 170 moves over the contraction body 155 and presses it against the outer surface 165 of the first plug receptacle 75, creating a non-positive, positive or frictional connection between them, by means of which the contact protection means 25 is attached to the charging socket 5. In order to release the contact protection means 25 again, it is only necessary to move the compression means 170 in the opposite direction of the arrow X.

A further embodiment of the invention is shown in FIGS. 6A to 6C, wherein the contact protection means 25, which now no longer has an essentially rectangular but an essentially elliptical cover body 30, is in a different position relative to the charging socket 5 in each case. Thus the contact protection means 25 in FIG. 6A has been completely removed from the charging socket 5 . The first power connection 15 is surrounded by a first collar portion 180 which is essentially elliptical and frames the former with the exception of a part adjacent to the second power connection 20 at a distance. The second power connection 20 is surrounded by a second collar portion 185 which is essentially elliptical and frames the former with the exception of a part adjacent to the first power connection 15 at a distance. Viewed from the side, the two collar sections 180, 185 have a shape corresponding to that of the collar section 95 shown in FIGS. 4A to 4G. A further description of the two collar sections 180, 185 is therefore omitted to avoid repetition.

If the second power connection 20 is to be covered by the contact protection means 25, the latter is first placed on the surface of the second power connection 20 through the second collar section 185, as can be seen in FIG. 6B. Consequently, the first power connection 15 is in an open position, while the second power connection 20 is in a covering position. For the purpose of locking the contact protection means 25 in the second collar section 185, this then only has to be rotated counterclockwise, as symbolized by the arrow XII, or clockwise (not shown), so that part of the side edge 40 faces the second collar section 185 located edge 45 and is covered by it, as can be seen in Fig. 6C. As a result, the contact protection means 25 is fastened to the charging socket 5 in a positive or non-positive manner. By moving the contact protection means 25 in the opposite direction, this operative connection can be canceled again. An additional embodiment of a charging socket 5 according to the invention together with contact protection means 25 is shown in FIGS. 7A and 7B. The charging socket 5 in turn has a charging socket holder 10 in which the first power connection 15 and the second power connection 20 located above it are provided. The second power connection 20 is covered by means of the contact protection means 25, which is therefore in a covering position. Since the contact protection means 25 is in an open position in relation to the first power connection 15 , a charging plug (not shown here) can be connected to the first power connection 15 alone. Consequently, the contact protection means 25 is in an open position in relation to the first power connection 15 .

The contact protection means 25 has a covering body 30 which bears against the charging socket holder 10 with its surface facing the charging socket 5 and covers the surface area formed by the second power connection 20 within a virtual plane spanned by the charging socket holder 10 . A handle 35 designed as a gripping element extends further out of the plane of the paper in FIGS. 7A and 7B in the direction of the observer and is fastened to the covering body 30 by means of two webs 190 and 195 lying opposite one another. Due to the construction selected in this way, it is possible for a user (not shown here) to reach at least partially into the space located between the grip element 35 and the covering body 30 in order to remove the contact protection means 25 after overcoming the magnetic force present between the contact protection means 25 and the charging socket holder 10 to remove the second power connector 20.

In Figure 7A, to the left and right of the covering body 30, a first contact protection means section 200 and second contact protection means section 210 protrude, which likewise have their respective surfaces facing the charging socket 5 against the charging socket holder 10, specifically against a first charging socket holder section 220 or . second charging socket holder section 225. A corresponding first charging socket holder section 220 or second charging socket holder section 225 is also located in the area of the first power connection 15, as can be seen in FIGS. 7A and 7B. In each of the charging socket holder sections 220 there is a first permanent magnet 230, which is directly visible in the area of the first power connection 15 due to the position of the contact protection means 25 selected in Fig. 7A and in the area of the second power connection 20 due to its covering by the webs 190, 195 is indicated by a dotted line. In addition, a second permanent magnet 235 is adequately located in each of the second charging socket holder sections 225.

According to the exemplary embodiment shown here, all the components of the contact protection means 25, with the exception of the first contact protection means section 200 and the second contact protection means section 210, are made of plastic. The latter, on the other hand, are made of a magnetizable metal, so that the first contact protection means section 200 and the second contact protection means section 210 rest against the first charging socket holder section 220 and the second charging socket holder section 225 over their entire surface due to the magnetic circuit. Overall, this creates a magnetic connection between the contact protection means 25 and the charging socket 10 . It should be noted that alternatively or in addition to the magnetizable metal of the first contact protection means section 200 or second contact protection means section 210, a magnet (not shown here) can be provided, which has the opposite polarity to the first permanent magnet 230 or second permanent magnet 235 . In this case, the entire contact protection means 25 can be made of a plastic.

FIG. 7B now shows a different fastening of the contact protection means 25 compared to FIG. 7A. Here the contact protection means 25 covers the first power connection 15, while the second power connection 20 is exposed to accommodate a charging plug, not shown here. Here, too, the first contact protection means section 200 and the second contact protection means section 210 are held in position in the first charging socket holder section 220 or second charging socket holder section 225 by the first permanent magnet 230 or second permanent magnet 235 by means of magnetic closure. To this extent, to avoid repetition, reference is made to the description of FIG. 7A. The two power connections 15, 20 described in the previously illustrated exemplary embodiments were each arranged one above the other. It should be noted, however, that although not depicted in the figures, these may be side by side.

It should be noted that the means shown above, in particular the contact protection means 25 in connection with the side edge 40 and the edge 45, the contact protection means 25 in connection with the projecting projection 60 or the projecting projections 60 and the optional receiving space 70, the contact protection means 25 in connection with the collar section 95, the contact protection means 25 in connection with the expansion body 115 and the widening means 140, the contact protection means 25 in connection with the contraction body 155 and the compression means 170, the contact protection means 25 in connection with the first collar section 180 and the second collar section 185 and finally the contact protection means 25 in connection with the first permanent magnet 230, the first contact protection means section 200, the second permanent magnet 235 and the second contact protection means section 210 alone or in combination form a fastening means in whole or in part.

Finally, it should be noted that the contact protection means 25 is fastened, depending on the design of the fastening means, with a force fit, a form fit, a friction fit or a combination of at least two of the corresponding types of force fit.
