Description

The present invention relates to a vehicle with a rechargeable by means of a charging cable and an external power supply storage device for electrical energy. The invention further relates to a cable receiving device with a charging cable for a vehicle.

For external charging of batteries of electrically driven vehicles, the vehicle is usually connected by means of a charging cable to a stationary power supply device (charging station). Wired charging of plug-in hybrid vehicles (PHEVs) and electric vehicles requires a charging socket on the vehicle side. This is conventionally accessible analogously to the tank filler neck hidden behind a fuel filler flap by a loading flap provided in the body. This charging socket forms an electrical connection element located behind the loading hatch. In addition, space in the vehicle for an entrained charging cable provided.

In the case of plug-in hybrid vehicles, an additional charging flap for the charging plug has thus far been required in addition to the fuel filler flap. Since hybrid vehicles and also pure electric vehicles are usually derived from conventional vehicles, this means that additional variants of the body must be provided. In cases in which own body styles must be generated, the costs are extremely high in individual cases, since for each basic body (right / left-hand drive, convertible, station wagon, etc.) a separate body variant must be created. The provision of such a tailgate in the body, possibly in addition to a fuel filler flap, is therefore not only expensive, since not only a special body version for electric vehicles must be provided in a vehicle family, but also a flap mechanism must be developed, manufactured and installed, whereby the Cost of an electric vehicle can be increased. Partly, the space for a tailgate is not available. In particular, when the charging cable is firmly installed in the vehicle and should be extendable from an opening behind a tailgate, it is difficult to find a location for a tailgate, behind which is sufficient space for the charging cable and a retractor available. The current position of a loading flap on the vehicle side wall is excluded in any case.

In addition, it is often undesirable for design reasons to provide such additional body flaps. It would therefore be advantageous if existing body openings could be used to carry out a charging cable.

From the DE 10 2011 051 052 A1 a charging station for electric vehicles with a cable reeling system is known in which the conventional charging cable is wound on a winding drum. This winding drum can be driven by a motor.

Also the WO 2009/091745 A2 shows a charging station with a rollable on a winding drum charging cable, the charging cable consists of two interconnected and juxtaposed circular lines. Guiding devices in front of the winding drum ensure that the cable does not twist during winding.

From the DE 10 2009 046 327 A1 is an electric vehicle with a built-in conventional charging cable is known, which is wound on a winding drum and unwound from this, wherein it is for this purpose from a laterally provided on the vehicle opening pulled out.

An intended in the vehicle reeling or winding mechanism for the charging cable is prone to error, since the provision of sliding contacts for winding the cable is required in previous concepts. Such sliding contact connections are expensive and prone to failure. In particular, make sure that the protective conductor is always connected. Furthermore, reeling mechanisms are always problematic because they become hot in the unrolled state due to ohmic losses in the cable and poor heat dissipation.

The DE 10 2011 121 303 A1 shows a vehicle with a withdrawable from a side opening charging cable, the charging cable is accommodated in a cable storage in the vehicle, which is located behind a separate body flap. The cable storage is provided with a spring acted upon by a deflection roller over which the cable is guided and which is displaced translationally against the force of the spring in the cable storage when pulling out of the charging cable from the cable storage.

A similar provided in a motor vehicle cable storage, but which is provided with a plurality of individual, each loaded by a spring and displaceable against the spring force pulleys, is from the DE 10 2009 057 659 A1 known.

However, these known, pulleys for the cable having cable storage take up a large space in the vehicle, which is generally not available for such purposes. In addition, there is a risk that the cable twisted during its useful life about its longitudinal axis and slides out of the pulleys or blocks.

The object of the invention is to provide a vehicle with a rechargeable by means of a charging cable and an external power storage device for electrical energy, which is provided with a reliable and reliable stored charging cable. Another object is to provide a charging cable storage for such a vehicle.

The vehicle-directed part of the object is achieved by a vehicle having the features of claim 1.

In such a vehicle according to the invention with a body which has at least one closable by a body flap body opening, wherein a charging cable, which is electrically conductively connected to the memory device is received on a provided inside the body cable receiving device in the idle state and for the use of the Body opening is pulled out, the invention provides that the charging cable is formed at least in the area as a flexible ribbon cable, which is receivable by the cable receiving device, and that the ribbon cable between an edge of the body opening and the body flap can be passed.

The use of a ribbon cable, ie a cable with a flat cross-section, as a charging cable has the advantage that the cable can be easily supported in the cable receiving device, so that a cable twist can be effectively prevented, whereby the reliability of the cable winder mechanism 'is increased. The ribbon cable can also take in the direction of the small cross section a very small bending radius. This can be done by existing column with closed vehicle openings (eg luggage compartment door), since the cable can adapt to the contour in the body opening and the existing seal in the body opening usually has an elasticity that allows the pass through small cable cross-section.

Further advantageous embodiments of the vehicle are specified by the dependent on claim 1 dependent claims.

Although the conductors in the ribbon cable can in principle have any desired cross-section (eg also round or oval), the ribbon cable in a preferred embodiment has juxtaposed flat current-carrying conductors and preferably a signal conductor surrounded by an electrically insulating sheath.

Preferably, viewed in cross section above and below the flat current-carrying conductors, the flat-ribbon cable has in each case an upper and a lower flat protective conductor which is likewise surrounded in each case by the electrically insulating sheath.

The flat current-carrying conductors and also the protective conductors can be formed, for example, by a thin metal band, several metal bands lying on top of one another and movable relative to one another, or a band-like mesh of thin electrically conductive wires. This inventive design of the charging cable, which is particularly suitable for use in the vehicle according to the invention, has the advantage that in case of damage to the ribbon cable section, for example, due to improper handling, the protective conductor is always located between the current-carrying conductors and the body or the body flap, so that the likelihood that in a damaged ribbon cable section, a live conductor in contact with the body ground, is significantly reduced.

The cable receiving device may comprise a winding mechanism, on which the ribbon cable is wound up. In this case, it is advantageous if a temperature sensor is provided in the region of a winding drum winding up the ribbon cable, which causes a shutdown of the charging process or a reduction in power in order to prevent inadmissible heating of the charging cable.

Particularly preferred is an embodiment in which the cable receiving device comprises a pulley-like pull-in mechanism, in which the ribbon cable is guided over at least one of an elastic member with a tensile force applied pulley.

An advantageous development of such a retracting mechanism is that the deflecting roller acted upon by an elastic element with a pulling force is part of a movable deflecting roller arrangement of a plurality of deflecting rollers acted upon jointly by the elastic element with the pulling force, wherein the flat cable extends over each of the deflecting rollers of the movable deflecting roller arrangement is guided, and that the ribbon cable in addition to the at least one of the elastic element acted upon by the tensile deflection roller is also guided over at least one fixed deflection roller.

It when the fixed guide pulley is part of a stationary deflection roller assembly of a plurality of fixed pulleys, wherein the ribbon cable over each of the fixed deflection rollers of the stationary deflection roller assembly is guided.

This feeder mechanism follows the principle of a pulley. Due to the small bending radius of the ribbon cable this "pulley" can be realized very flat with small wheels. Since the individual recorded in this feed mechanism cable sections do not abut each other, but determine spaces between each other, is a heat dissipation, for. B. possible by air convection. Thus, regardless of the degree with which the cable is pulled out, the maximum current flow is possible.

The pulleys allow a clear guidance of the ribbon cable from the point where the cable is passed through the gap between the body opening and the body flap to the outside, to the feed mechanism.

The feeder mechanism can be arranged for example at a suitable location in the luggage compartment. The defined cable routing also allows an enclosure of the cable in a cable duct to protect the charging cable. For this purpose, the vehicle can advantageously be provided in the region of the inner edge of the body opening with a cable guide device, through which the ribbon cable from the cable receiving device to the edge of the body opening can be guided.

Preferably, the ribbon cable is guided in front of the cable receiving device by a cable cleaning device. The resulting self-cleaning of the charging cable when pulling into the cable receiving device ensures that the part of the charging cable located in the vehicle remains clean. It is also advantageous that only as much has to be removed from the charging cable, as is actually required. So there will always be little or no part of the charging cable outside the vehicle on the ground. Since the cleaning mechanism can also wipe off water, freezing of the charging cable accommodated in the cable receiving device is prevented.

With the solution according to the invention a very comfortable implementation of the on and Absteckvorgangs the charging cable while protected housing the charging cable in the luggage compartment is possible. The cable does not have to be rolled up by hand and placed in a separate place in the vehicle from the tailgate.

The part of the object directed to the cable receiving device is achieved by the cable receiving device with the features of claim 13. The advantages of this cable receiving device correspond to the already described advantages of the built in the vehicle cable receiving device. Further advantageous embodiments of this cable receiving device are specified in the dependent claims.

1 shows a vehicle according to the invention 1 , in which as a ribbon cable 20 equipped charging cable 2 by a luggage compartment opening forming body opening 10 passed through. The charging cable 2 is in a inside of the body, for example in the luggage compartment, arranged cable receiving device 4 ( 6 ) intended. In the passage area between the luggage compartment opening 10 and a luggage compartment door forming the body flap 12 is the flat charging cable 2 when the boot lid is closed 12 in the body gap 18 between the upper edge of the luggage compartment opening 10 and the lower edge of the boot lid 12 positioned without the charging cable 2 is squeezed, as based on the 2A and 2 B will be explained. The charging cable 2 is only clamped in the context of sealing elasticity.

The ribbon cable 20 has a flat top 20 ' and a flat bottom 20 '' on and is at least partially provided with a soft, elastic surface to leave no contact with the body surface scratches.

2A and 2 B show a vertical section through the vehicle body in the luggage compartment door 12 , The as a ribbon cable 20 trained charging cable 2 gets over the body-fixed lower edge section 14 the luggage compartment opening 10 and the seal attached to it 16 laid as in 2A is shown. The luggage compartment flap 12 is then closed ( 2 B ), where the ribbon cable 20 between the lower edge of the boot lid 12 and the seal 16 due to the elasticity of the seal 16 gently pinched. The thickness of the as a ribbon cable 20 trained charging cable 2 is less than the height of the body gap 18 between the bottom edge 13 the luggage compartment lid 12 and the adjacent upper edge 15 of the body-fixed edge section 14 the luggage compartment opening 10 , Due to this very flat design of the ribbon cable 20 and its associated high bending flexibility, the ribbon cable can 20 the contours of the lower edge of the boot lid 12 and the lower edge section 14 the luggage compartment opening 10 to adjust. The ribbon cable 20 this way through the existing body cleft 18 between the bottom edge 13 the luggage compartment lid 12 and the adjacent upper edge 15 of the body-fixed edge section 14 the luggage compartment opening 10 be passed without causing the ribbon cable 20 crushed or kinked beyond a permitted bending radius addition. The elasticity of the seal 16 allows the damage-free implementation of the ribbon cable 20 through the gap 18 between the body opening 10 and the boot lid 12 ,

3 shows a cross section through the ribbon cable 20 , The electrical conductors in the ribbon cable 20 are designed as flat, band-shaped conductors. For example, they can be formed by a wire mesh. A first live conductor 21 and a second live conductor 23 are arranged side by side in a middle level. In addition to the live conductors 21 . 23 is a signal conductor in the middle level 25 arranged, which is also designed as a flat, band-shaped conductor. Above the middle level and thus above the live conductor 21 . 23 and the signal conductor 25 is an upper, flat protective conductor 27A provided, which laterally over the arranged in the middle plane current-carrying conductor 21 . 23 as well as the signal conductor 25 also available. Below the middle level and thus below the live conductor 21 . 23 and the signal conductor 25 is a lower, lower protective conductor 27B provided, which also laterally over the arranged in the middle plane current-carrying conductor 21 . 23 as well as the signal conductor 25 also available.

The live conductors 21 . 23 , the signal conductor 25 as well as the upper protective conductor 27A and the lower protective conductor 27B are from an electrically insulating sheath 29 surround. The electrically insulating shell 29 can, as in 3 is shown schematically, the ladder 21 . 23 . 25 . 27A and 27B envelop each immediately; but it can also be any of the leaders 21 . 23 . 25 . 27A . 27B first surrounded by its own insulation and then in the insulating shell 29 be embedded.

The flat design of the ribbon cable 20 allows good flexibility in one direction and gives high rigidity in the orthogonal direction. Due to a protective conductor monitoring and a shutdown in the event of a fault, the insulation requirement for a simple insulation by means of the electrically insulating sheath 29 be reduced. This is a major contribution to the flat, flexible and easily bendable design of the cable. This construction is possible by the provision of an existing in the charging cable or in a charging station RCD, which breaks the flow of current in a cable break or cable damage when one of the protective conductor is exposed and with the vehicle body or with a live conductor in contact.

In "vertical direction" of the ribbon cable 20 , that is, in the direction of the shorter cross-sectional dimension, arise due to an unnecessary double insulation very small Dimensions. The conductor cross sections are designed so that typical charging power is possible for PHEV vehicles. To further increase the flexibility, the conductors can be layered. Instead of a metal layer with 0.1 mm or 0.05 mm thickness several layers with z. B. 0.01 mm thickness can be used.

Another part of the invention consists of a in the cable receiving device 4 provided cable entry mechanism 40 , Here also the flat cable cross-section or the small bending radius is utilized.

4 shows that such a cable pulling mechanism 40 underlying principle of a pulley. The cable entry mechanism 40 has a movable pulley arrangement 42 and a stationary pulley arrangement 44 on. The stationary pulley arrangement 44 is directly or indirectly connected to the vehicle body. The movable pulley arrangement 42 is about an elastic element 46 forming tension spring also indirectly connected to the vehicle body, but linearly movable. In this way, the movable pulley arrangement 42 relative to the stationary pulley arrangement 44 under the force of the elastic element 46 along a movement line G translationally movable. The movable pulley arrangement 42 For this purpose, it is translatorily guided in a manner known to those skilled in the art.

The movable pulley arrangement 42 has, for example, three pulleys 42 ' . 42 '' . 42 ''' on whose axes of rotation lie on the translational line G and which are larger in diameter from the inside out. Also the stationary pulley arrangement 44 has several pulleys 44 ' . 44 '' on whose axis of rotation is also on the translational straight line G and whose diameter is also larger from the inside out. The ribbon cable is in the area of the stationary deflection roller arrangement 44 fixed and comes with a connection section 20A that with a fastener 20B is provided laterally from the cable retraction mechanism 40 led out. The ribbon cable 20 is, starting with the innermost smallest role 42 ' the movable pulley arrangement 42 as in a pulley to the respective roles of the stationary pulley arrangement 44 and the movable pulley assembly 42 guided and runs from the largest pulley 42 ''' the movable pulley arrangement 42 in the direction of the cable outlet opening of the vehicle, ie in the example shown the 1 to the rear body opening 10 , Here are the individual on the cable entry mechanism 40 lying sections of the flat cable 20 spaced apart, so that an air space is formed therebetween, through which heat can be removed from the cable.

The charging cable can thus in the direction of the arrow Z with a against the spring force F of the elastic element 46 acting tensile force from the cable entry mechanism 40 be pulled out. In the opposite direction, the spring force F pulls the charging cable when the traction decreases 2 back in the feeder mechanism 40 into it. This is through the two double arrows in 4 symbolically represented.

As in 4 is shown, very space-saving feed concepts can be realized because very small bending radii are possible. No sliding contacts are needed as the cable does not torsionally move. According to 4 a spring is used to generate the pull-in force. Alternatively, an electric actuator may be provided as a traction drive. When using a spring is a (not shown) lock for the charging cable 2 intended. This will be a permanent tension of the charging cable 2 avoided.

The winding mechanism forming a winding mechanism 40 ' is with an outer winding drum 41 provided on the extendable cable supply is rolled up. This outer winding drum 41 determines the rotating part of the cable reeling mechanism 40 ' , An inner, fixed, designed as a hollow tube drum axis 43 is by means of a coil spring with the outer drum 41 connected, causing the outer drum 41 relative to the inner drum axis 43 against the force of the (not shown) clock spring is rotatable. The spring force F 'of the coil spring is indicated by the curved arrow in FIG 5 symbolically represented. The extendable cable supply 200 as a flat cable 20 trained charging cable 2 is on the outer drum 41 rolled up. Inside the outer drum 41 is a cable reserve 210 of the ribbon cable 20 provided on the inner drum axis 43 rolled up and with her free end in the on the outer drum 41 wound part 200 of the ribbon cable 20 passes. When pulling out the ribbon cable from the cable reeling mechanism 40 ' in the direction of the arrow Z 'against the spring force F' is the charging cable 2 from the outer drum 41 unwound and simultaneously on the inner, fixed drum axis 43 rolled up. Through the cavity 43 ' the fixed drum axis 43 is the local free end of the charging cable 2 led out and is connected via a corresponding connection means to a provided in the vehicle wiring harness.

The cable retraction mechanism can, in particular in the case of clock spring ( 5 ), be provided with a temperature sensor which causes a shutdown of the charging or a power reduction, to further heating the charging cable 2 to prevent.

6 and 7 show the cable entry mechanism 40 of the 4 as part of an underbody in the luggage compartment of the vehicle 1 built-in cable receiving device 4 , The elastic element 46 is here as a tension spring 46 ' formed, which are parallel to each other from the movable pulley arrangement 42 to the stationary pulley arrangement 44 extending part of the ribbon cable 20 is arranged. The tension spring 46 ' is about a cable 46 '' , which has two pulleys 47 . 47 ' is guided, with the movable pulley arrangement 42 and connected to the other end of the body.

The as a ribbon cable 20 trained charging cable 2 is in the direction of the vehicle rear of the cable receiving device 4 under the luggage compartment floor 17 guided and occurs there up through the luggage compartment floor 17 through in a cable guide device 5 one. The cable management device 5 has one the flat cable 20 surrounding shaft 50 in which a lower pulley 52 and an upper pulley 54 for the flat cable 20 are provided to the the flat cable 20 is lying around. The cable management device 5 extends into the in 6 illustrated standby position from the luggage compartment floor 17 to the top 11 the luggage compartment opening 10 , Just above the upper edge 11 the luggage compartment opening 10 enters the ribbon cable 20 from the cable guide device 5 out and will, as in 2 B is shown between the luggage compartment opening 10 and the closed boot lid 12 through the body gap 18 led to the outside.

Is the charging process complete and the charging cable 2 again in the cable receiving device 4 recorded, so is the cable guide device 5 around the axis of the lower pulley 52 pivoted inwards (forward in the direction of travel) by 90 ° and comes on the luggage compartment floor 17 to lie. Of course, it is also possible, the cable guide device 5 to design them in their (in 7 shown) rest position under the luggage compartment floor 17 to come to rest. The with a connection device, such as a power plug 20C , provided free end of the charging cable 2 can do this in a holding device 20D for the connection device 20C be fixed.

For clean guidance of the charging cable 2 at the point of passage through the body opening 10 is with the cable management device 5 proposed a guide mechanism, which is an oblique bending of the charging cable 2 when closing the body flap 12 prevented. This cable guide device can be hinged to a buckling of the charging cable in both cases, with the door closed with and without outward led charging cable (cable is completely in the luggage compartment) 2 to prevent
