Description

The invention relates to a fastening arrangement for a charging socket on the body of a motor vehicle according to the preamble of claim 1. Furthermore, the invention relates to a motor vehicle, in particular a car, with such a fastening arrangement.

The EP 2 904 667 B1 Disclosing a modular system for forming a charging socket of a charging device for charging an electrical storage device of a vehicle. From the WO 2016/020512 A1 A vehicle is known to have a storage device for electrical energy that can be recharged by means of a charging cable and an external power supply. DE 10 2019 122 427 A1 It reveals a body shell for an electric vehicle. DE 10 2022 101 394 A1 A motor vehicle with a charging connection unit for electrical coupling to an external energy source is known. Furthermore, the CN 117401041 A a loading, refueling or service hatch for covering a loading, refueling or service recess that is attached to or can be attached to a housing.

The object of the present invention is to provide a fastening arrangement and a motor vehicle with such a fastening arrangement, so that a charging socket for electrically charging an electrical energy storage device of a motor vehicle can be particularly advantageously attached to a body of the motor vehicle.

This problem is solved according to the invention by a fastening arrangement having the features of claim 1 and by a vehicle having the features of claim 10. Advantageous embodiments of the invention are the subject of the dependent claims.

A first aspect of the invention relates to a mounting arrangement for a charging socket on the body of a motor vehicle, preferably designed as a self-supporting body, which is also referred to simply as a vehicle. The interior of this vehicle, also referred to as the passenger compartment, passenger cell, or cabin, is formed by the body. This means that the motor vehicle, in its fully manufactured state, comprises the mounting arrangement and thus the charging socket and the body. Preferably, the motor vehicle is designed as a motor vehicle, in particular as a passenger car. The motor vehicle is, for example, designed as a hybrid vehicle or as an electric vehicle, in particular as a battery electric vehicle (BEV). In its fully manufactured state, the motor vehicle has an electrical energy storage device in or by means of which electrical energy, in particular electrochemically, is to be stored. Preferably, the electrical energy storage device is a high-voltage component whose electrical voltage, in particular its operating or nominal voltage, is preferably greater than 50 volts, in particular greater than 60 volts, and most preferably several hundred volts. Furthermore, for example, in its fully manufactured state, the motor vehicle has at least one electric machine by means of which the motor vehicle can be driven, in particular purely, electrically. Preferably, the electric machine is designed as a high-voltage component whose electrical voltage, in particular its operating or nominal voltage, is preferably greater than 50 volts, particularly greater than 60 volts, and most preferably several hundred volts. The electric machine can be supplied with the electrical energy to be stored or stored in the energy storage device, thereby enabling the electric machine to be operated as a motor. The motor vehicle can be driven, in particular purely, electrically by means of the electric motor. The electrical energy storage device can be supplied and charged via the charging socket with electrical energy, which can be provided, for example, by an energy source external to the motor vehicle and thus located outside the vehicle, such as a charging station, since the electrical energy with which the electrical energy storage device can be supplied or is supplied via the charging station can be stored in the electrical energy storage device.

The charging socket is designed to be connected to a charging plug in a non-destructive and therefore reversible manner, such that the charging socket and the charging plug are at least electrically and preferably also mechanically connected. As a result of the electrical connection between the charging plug and the charging socket, the electrical energy that can be provided or is provided by the energy source via the charging plug can be transferred from the charging plug to the charging socket. From the charging socket, the electrical energy can be transferred to the electrical energy storage device and subsequently stored in the electrical energy storage device, thereby charging the electrical energy storage device. For example, the charging socket and the charging plug can be connected at least electrically and preferably also mechanically by means of a plug connection. For example, the charging socket has at least one electrical contact element that can be electrically contacted and thus connected to a corresponding electrical contact element of the charging plug, in particular by means of an electrical connection. Connecting the charging plug to the charging socket. For example, the charging socket is connected to the electrical energy storage device via a cable, through which the electrical energy that can be transferred or is transferred from the charging plug to the charging socket is to be carried from the charging socket to the electrical energy storage device, so that the electrical energy storage device can be supplied via the cable with the electrical energy transferred from the charging plug to the charging socket.

In this mounting arrangement, the charging socket, which is separate from the vehicle body, is attached to the vehicle body, in particular in such a way that relative movement between the charging socket and the body is prevented. The charging socket has, for example, a housing, also referred to as a socket housing or charging socket housing, which is connected, for example, separately from the electrical contact element of the charging socket and is connected at least indirectly, in particular directly, to the electrical contact element of the charging socket. For example, the housing has a recess in which the electrical contact element of the charging socket is received, at least partially, in particular at least predominantly and thus at least more than halfway or completely.

The vehicle body has a side wall that at least partially defines the interior of the vehicle in the transverse direction. The vehicle body is also referred to as the body shell, and since the side wall is a component of the vehicle body, it is part of the aforementioned body shell. The side wall comprises an inner section and an outer section, which is formed separately from the inner section and connected to it at least indirectly, and in particular directly, by which the inner section is at least partially covered and thus clad, especially in the transverse direction. Therefore, the outer section is also referred to, for example, as a paneling element or outer paneling element. The outer section forms part of the vehicle's outer skin, the outer skin of which, in the fully manufactured state of the vehicle, can be perceived visually and haptically by a person in the vicinity of the vehicle; that is, seen and directly touched.

To enable the charging socket to be attached to the vehicle body in a particularly advantageous manner, the invention provides that a support element, designed separately from the vehicle body and thus separately from the inner part, the outer part, and the charging socket itself, is connected to the inner part, preferably directly. It is preferably provided that the support element, also simply referred to as the carrier or support element, is attached to the inner part, particularly completely, i.e., entirely, bypassing the outer part. The feature that a first element, such as the support element, is attached to a third element, such as the inner part, bypassing a second element, such as the outer part, means that the first element is not attached, or not only attached, via the second element. The characteristic that the first element is completely, that is, entirely, attached to the third element bypassing the second element, means that the first element is not attached to the third element at all via the second element, so that any attachment of the first element to the third element via the second element is entirely, that is, completely, absent. The characteristic that the first element is connected to the third element, in particular completely and thus entirely, bypassing the second element, is synonymous with the characteristic that the first element is attached to the third element, in particular completely and thus entirely, bypassing the second element. Thus, the characteristic that the first element is connected to the third element bypassing the second element means that the first element is not connected to the third element, or not only connected via the second element. Accordingly, the characteristic that the first element is completely and thus entirely connected to the third element, bypassing the second element, means that the first element is not, that is, not at all, connected to the third element via the second element, so that a connection of the first element to the third element via the second element is completely, that is, entirely omitted.

Since the support element is preferably connected to the inner part, and thus completely and entirely, bypassing the outer part, and is thereby attached to the inner part, particularly in such a way that relative movements between the support element and the inner part are prevented, it can be avoided, for example, that loads acting on the support element are excessively transferred from the support element to the outer part. This prevents, for example, damage and excessive deformation of the outer part.

The invention also provides that the charging socket is attached to the carrier part, bypassing the inner and outer parts. In other words, the charging socket is attached, in particular entirely and thus completely, to the carrier part, bypassing the inner and outer parts. The charging socket is attached to a separate support bracket. This prevents excessive loads from the charging socket from being transferred to the outer part. Loads acting on the charging socket can, for example, be transferred from the charging socket to the support bracket and from the support bracket to the inner part, thus preventing excessive stress on the outer part.

The mounting arrangement also includes a flap unit, designed separately from the charging socket, the vehicle body, and thus separately from the inner and outer parts, as well as separately from the support part. This flap unit features a charging flap, also referred to simply as a flap. Furthermore, the invention provides that the outer part has a through-opening which is arranged in at least partial overlap with the charging socket. Thus, for example, the charging socket is at least partially, and in particular at least predominantly, and therefore at least more than halfway or completely, overlapped by the through-opening of the outer part in the transverse direction of the vehicle. The flap unit is connected, in particular directly, to the charging socket and thereby attached to the support part and the inner part via the charging socket. The charging flap of the flap unit is movable relative to the vehicle body, the charging socket, and the support part between a closed position and at least one open position, and in particular pivotable about a pivot axis. In the closed position, the charging flap closes at least a portion of the through-opening. In the open position, the charging flap exposes at least a portion of the opening, allowing the charging plug (also simply called a connector) to be inserted through it, particularly in the transverse direction of the vehicle, thus electrically connecting it to the charging socket. In the closed position, the charging flap at least partially, and in particular at least predominantly or completely, closes the opening, specifically such that the flap assembly completely seals the opening. This prevents objects such as dirt and water from the vehicle's surroundings from passing through the opening when the charging flap is closed.

The support element is made of a metallic material, particularly a sheet metal part, so that, for example, the support element is designed as a support sheet. Since the support element is formed separately from the inner part and connected to it, the support element is joined to the inner part. There is no mechanical connection between the support element and the outer part, and thus between the support element and the outer skin, so that no direct force transmission exists or occurs between the support element and the outer part. This advantageously prevents deformation and damage to the outer part.

The support element has, for example, at least one or more bolts. The charging socket is connected to the support element by means of the bolt, in particular by screwing. For example, the bolt engages in a corresponding receptacle of the charging socket, in particular of the housing. The receptacle of the charging socket is, for example, designed as a further through-opening, which is, for example, penetrated by the bolt. A screw element is provided, for example, separately from the charging socket and separately from the bolt, and designed, for example, as a nut, which is, for example, screwed, in particular, directly, to the bolt, in particular screwed onto the bolt. The charging socket is connected to the support element by means of the bolt and by means of the screw element.

In an advantageous embodiment of the invention, the flap unit is directly connected to the charging socket. This prevents, for example, excessive force transmission from the flap unit to the outer part. Instead, loads can be transferred from the flap unit to the charging socket and from there to the support part and the inner part, thus avoiding excessive stress on the outer part.

In order to prevent excessive ingress of particles and liquids from the environment of the motor vehicle into the charging socket, a further embodiment of the invention provides that the flap unit is sealed, in particular directly, against the outer part.

It has proven particularly advantageous if, with the exception of sealing the flap unit against the outer part, no connection exists between the flap unit and the outer part. In other words, for example, by sealing the flap unit against the outer part, the flap unit is supported by the outer part, but no connection between the flap unit and the outer part beyond this support is provided. This means it is avoided and prevented. This prevents excessive loads from being transferred from the flap unit to the outer part, thus advantageously avoiding excessive stress on the outer part.

Furthermore, it is possible that the flap unit is mechanically connected to the outer part, particularly directly, for example by the flap unit being locked, i.e. clipped, to the outer part, particularly in the area of the sealing of the flap unit against the outer part.

It has proven particularly advantageous to avoid a direct mechanical connection between the outer part and the charging socket. This means that the charging socket is not directly mechanically connected to the outer part. Preferably, the charging socket is connected to the support part, and thus completely, bypassing the outer part, and is thereby attached to the support part, particularly in such a way that relative movement between the support part and the charging socket is prevented. This prevents, for example, excessive transfer of loads acting on the support part and/or the charging socket to the outer part. This, in turn, prevents damage and excessive deformation of the outer part.

Another embodiment is characterized in that the flap unit has a frame connected to the charging socket, particularly directly, and sealed against the outer part. Furthermore, the flap unit includes the charging flap, which is movably held on the frame between the closed and open positions relative to the frame, the vehicle body, the support part, and the charging socket, and is pivotable about the pivot axis. Preferably, the charging flap is designed separately from the frame and is movably, and in particular pivotably, held on the frame. Thus, the flap can be moved between the closed and open positions relative to the frame, the vehicle body, the support part, and the charging socket, while, for example, relative movement between the frame and the outer part is prevented, and the frame remains sealed against the outer part. This advantageously avoids excessive stress and thus damage and excessive deformation of the outer part.

In order to achieve a particularly advantageous connection of the charging socket to the bodywork, it is further provided in the invention that the support part is welded to the inner part, in particular directly.

In a further embodiment of the invention, the support part has a cup-shaped cross-section, whereby, for example, the support part projects outwards in the transverse direction of the vehicle from the inner part, which is directly adjacent to the support part. This allows for an advantageous offset in the transverse direction of the vehicle, also referred to as a y-offset, which makes it particularly advantageous to connect the charging socket to the vehicle body.

In a further embodiment of the invention, the support part has a first wall thickness and the inner part has a second wall thickness that is smaller than the first. This allows loads to be advantageously transferred from the charging socket to the support part, while simultaneously keeping the weight of the car body to a particularly low level.

In a further embodiment of the invention, it is provided that the charging socket, in particular the housing of the charging socket, at least partially delimits a recess, also referred to as a receiving area. It is conceivable that the recess is partially delimited by the charging socket, in particular the housing of the charging socket, and partially by the flap unit, in particular the frame, and in particular directly delimited. When the charging flap is open, that is, when the charging flap is in the open position, water from the surroundings of the vehicle can, for example, flow through the opening, i.e., through the exposed portion of the opening, and enter the recess.

To drain water quickly, precisely, and in a controlled manner from the recess, a further embodiment of the invention provides that the mounting arrangement includes a conduit element, which is designed separately from the charging socket, the vehicle body, the support part, and the charging flap. This conduit element is fluidically connected to the recess, particularly by the fact that it opens directly into the recess. Water collecting in the recess can be introduced into the conduit element, allowing water from the recess to flow through it. This drainage process also refers to the removal of water from the recess.

The conductor element runs, for example, at least partially, in particular at least over The inner part is located on a rear side facing away from the outer part and, for example, inwards in the transverse direction of the vehicle. A so-called drying chamber is arranged on the rear side of the inner part, through which the drainage element runs. This allows the water from the recess to be conveyed through the drying chamber by means of the drainage element, without the water from the recess entering the drying chamber. This enables effective drainage. The drainage element, which opens into the recess at one end, opens, for example, at the other end into an underfloor area of the vehicle body, the underfloor area of which is located, for example, in the vertical direction of the vehicle below a floor of the vehicle body. For example, the interior space of the vehicle is at least partially, and in particular at least predominantly, and thus at least more than halfway or completely, bounded downwards by the floor of the vehicle body. The water flowing through the pipe element can escape from the pipe element in the underfloor area and thus enter the underfloor area, advantageously preventing water from entering the aforementioned drying compartment and any other drying compartment of the vehicle. This provides effective drainage of the trough.

A second aspect of the invention relates to a motor vehicle, also referred to simply as a vehicle, and preferably designed as a motor car, in particular as a passenger car, which has a fastening arrangement according to the first aspect of the invention. Advantages and advantageous embodiments of the first aspect of the invention are to be regarded as advantages and advantageous embodiments of the second aspect of the invention and vice versa.

1 Figure 1 shows a partial schematic sectional view of a body 1 of a motor vehicle, also referred to simply as a vehicle, designed as a self-supporting body and also called the body shell. The interior of the vehicle, also referred to as the passenger cell, passenger compartment, or cabin, is formed by the body 1. During a journey, persons such as the driver of the motor vehicle may be present in the interior. The motor vehicle is designed as a passenger car and thus as a motor vehicle. Based on 1 to 4 The following describes a mounting arrangement 2 for a charging socket 3 on the vehicle body 1. The charging socket 3 is, for example, a multi-part assembly and can be detached without damage and thus reversibly connected, at least electrically, to a charging plug not belonging to the vehicle. An energy source, for example, external to the vehicle and thus located outside the vehicle, i.e., in an environment 4 of the vehicle and thus the vehicle body 1, can provide electrical energy via the charging plug. By electrically connecting the charging plug to the charging socket 3, the electrical energy can be transferred from the charging plug to the charging socket 3. The vehicle has an electrical energy storage device, which is also referred to as a battery and is preferably designed as a high-voltage battery (HV battery). For example, via a cable, in particular a high-voltage cable, the electrical energy can be transferred from the charging socket to the energy storage device and stored in the energy storage device, thereby charging the energy storage device with the electrical energy. As will be explained in more detail below, in this mounting arrangement the charging socket is attached to the body 1 and thus connected to the body 1.

The body 1 has a side wall 5, also referred to as a side frame, which at least partially delimits the interior space in the transverse direction of the vehicle. It can be seen that the side wall 5 has two lateral door openings, successive in the longitudinal direction of the vehicle, namely a first door opening 6 and a second door opening 7. Each door opening 6, 7 is a respective passageway opening of the sides. The side wall 5 is formed. In the fully assembled state of the motor vehicle, each door opening 6, 7 is assigned a respective side door, which is held on the body 1 so that it can be moved, in particular pivoted, between a respective door closed position and at least one respective door open position relative to the body 1. In the respective door closed position, the respective side door closes at least a respective portion of the respective door opening 6, 7 that is assigned to the respective side door. In the respective door open position, the respective side door releases the respective portion of the respective door opening 6, 7, so that, for example, a person initially located in the vicinity 4 can enter the interior through the released portion of the respective door opening 6, 7. Extending longitudinally to the rear of the vehicle, a lateral window opening 8, also referred to as a window opening, adjoins the door opening 6 and the door opening 7. This window opening serves as a further passageway opening. In the fully manufactured state of the motor vehicle, the window opening 8 is covered and thereby closed by a corresponding, translucent side window, wherein the side window, which is formed separately from the body 1, is connected to the body 1 and thus attached to the body 1, in particular in such a way that relative movements between the side window and the body 1 are prevented. 1 Also visible is a lateral, rear wheel arch 9 of the side wall 5. From a combination of 1 and 2 It can be seen that the charging socket 3 extends upwards in the vehicle's vertical direction to the wheel arch 9 and at least partially to the rear in the vehicle's longitudinal direction, with the charging socket 3 being positioned higher than the wheel arch 9 and lower than the window opening 8 in the vehicle's vertical direction. Furthermore, the charging socket 3 extends rearwards in the vehicle's longitudinal direction to the door openings 6 and 7, as well as at least partially to the window opening 8.

Out of 2 It is evident that the side wall 5 of the body 1 has an inner part 10 and an outer part 11, which is formed separately from the inner part 10 and is connected to the inner part 10 at least indirectly, and in particular directly, in such a way that relative movements between the inner part 10 and the outer part 11 are prevented. The inner part 10 is at least partially, and in particular at least predominantly, covered and thus at least more than halfway or completely, by the outer part 11 in the transverse direction of the vehicle, and thus enclosed, with the outer part 11 adjoining the inner part 10 in the transverse direction of the vehicle. The outer part 11 forms part of an outer skin 12 of the vehicle, the outer skin 12 of which, in the fully manufactured state of the vehicle, is visually and haptically perceptible to persons in the vicinity 4, i.e., it can be seen and directly touched.

In order to connect the charging socket 3 to the body 1 particularly advantageously, and thus to attach it to the body 1 particularly advantageously, a support part 13, which is formed separately from the inner part 10 and separately from the outer part 11 and which in this case has a cup-shaped cross-section, is connected to the inner part 10 of the body 1, in particular directly, for example, by welding the support part 13 directly to the inner part 10. In the embodiment shown in the figures, the support part 13 is connected to the inner part 10 directly, in particular by welding, bypassing the outer part 11. The charging socket 3, which is formed separately from the inner part 10, separately from the outer part 11, and separately from the support part 13, is attached to the support part 13 directly, in particular bypassing the inner part 10 and the outer part 11. The characteristic that the charging socket 3 is attached to the carrier part 13 completely bypassing the inner part 10 and completely bypassing the outer part 11, i.e., is connected to the carrier part 13, means that a connection of the charging socket 3 to the carrier part 13 via the outer part 11 and a connection of the charging socket 3 to the carrier part 13 via the inner part 10 is completely omitted, i.e., not provided for.

In the mounting arrangement 2, a flap unit 14 is also provided, which is designed separately from the charging socket 3, separately from the body 1, and separately from the support part 13. Furthermore, the outer part 11 has a through-opening 15, which is arranged in at least partial overlap with the charging socket 3. As a result, the charging socket 3 is at least partially overlapped outwards by the through-opening 15 in the transverse direction of the vehicle. For example, the flap unit 14 is arranged at least partially in the through-opening. The flap unit 14 is connected, in particular directly, to the charging socket 3 and associated with the through-opening. The flap unit 14 has a charging flap 16, also simply referred to as a flap, which, for example, forms another part of the outer skin 12. The charging flap 16 is located relative to the body 1, relative to the charging socket 3, and relative to the support part 13 between a 1 and 2 The closed position S shown and at least one open position can be pivoted about a pivot axis and thus moved. 1 Is the charging port 16 displayed transparently, so that in 1 The charging socket 3, located behind the charging flap 16 in the transverse direction of the vehicle, is visible in the closed position S. In the closed position S, at least a portion of the passage opening 15 is closed by the charging flap 16, in particular such that the passage opening 15 is completely closed by the flap unit 14 in the closed position S. In the open position, the charging flap 16 releases at least that portion of the passage opening 15. In particular, in the closed position S, at least a portion of the charging socket 3 is overlapped outwards by the charging flap 16 in the transverse direction of the vehicle. In the open position, the charging flap 16 is arranged without overlap with at least that portion of the charging socket 3.

In the embodiment shown in the figures, the flap unit 14 is directly connected to the charging socket 3, in particular to a housing of the charging socket 3.

In the embodiment shown in the figures, the flap unit 14 comprises the charging flap 16 and a frame 17 on which the charging flap 16 is pivotably mounted about the pivot axis between the closed position S and the open position, bypassing the inner part 10 and the outer part 11. In particular, the frame 17 is directly connected to the charging socket 3. Furthermore, it is preferably provided that the frame 17 and the flap unit 14 as a whole are connected to the charging socket 3, in particular directly, bypassing the support part 13 and the inner part 10. The frame 17, and thus the flap unit 14, is sealed against the outer part 11, whereby, with the exception of this seal of the flap unit 14 against the outer part 11, a connection between the flap unit 14 and the outer part 11 is omitted, i.e., not provided.

Frame 17 is in 4 shown in a schematic sectional view. It can be seen that the frame 17 has a rigid base body 18, for example made of plastic, which is provided with a first sealing element 19 and a second sealing element 20. The frame 17, which is separate from the charging socket 3, is sealed against the charging socket 3 by means of the sealing element 19. The frame 17, and thus the entire flap unit 14, is sealed against the outer part 11 by means of the sealing element 20.

For example, the charging socket 3 is positioned in the transverse direction of the vehicle from the inside out relative to the support part 13, and thus attached to the support part 13, so that, for example, the charging socket 3 is attached to the support part 13 from the inside. In particular, after the charging socket 3 has been attached to the support part 13, the flap unit 14 is moved in the transverse direction of the vehicle from the outside in relative to the body 1, the support part 13, and the charging socket 3, in particular such that the flap unit 14, in particular the frame 17, is moved through the passage opening 15, in particular inserted through it. This connects the frame 17 to the charging socket 3, in particular directly, and seals it against the charging socket 3, in particular via the sealing element 19, and also seals it against the outer part 11, in particular by means of the sealing element 20.

In 3 A parapet is designated by 21. A luggage compartment floor of the body 1 is designated by 22, wherein the luggage compartment floor 22 at least partially, in particular at least predominantly or completely, limits a storage area of the motor vehicle, particularly at the rear, also referred to as a trunk or luggage compartment, in the vertical direction of the motor vehicle. A rear wheel arch of the body 1 forming the rear wheel arch 9 is designated by 23. Furthermore, in 3 Screw connections 24 are used to screw the charging socket 3 to the support part 13, thereby attaching it to the support part 13 and connecting it to the support part 13. Each screw connection 24 comprises, for example, a bolt of the support part 13. A screw element of the screw connection 24, for example designed as a nut, is associated with each bolt, and the bolt is screwed directly to the associated screw element. This secures the charging socket 3 to the support part 13.

Drying compartments of the motor vehicle, in particular those arranged in the transverse direction of the vehicle between the inner part 10 and the outer part 11, are in 2 labelled 25 and 26.

Another drying compartment of the motor vehicle is designated 27. It can be seen that the drying compartment 27 is located on a rear side RS of the inner part 10 facing away from the outer part 11, the rear side RS of which, for example, points inwards in the transverse direction of the vehicle.

Out of 2 It is also apparent that a receiving area 28, also referred to as a trough and designed as such, is partially bounded by the charging socket 3 and partially by the frame 17, in particular directly in each case. In the closed position S, the charging flap 16 prevents dirt and other particles as well as water from escaping from the surrounding area. In the open position, water from the surrounding environment 4 can penetrate through the opening 15 and enter the receiving area 28. However, when the charging flap 16 is open, water from the surrounding environment 4 can penetrate through the opening 15 and thus enter the receiving area 28. To quickly, precisely, and in a controlled manner drain the water that has entered the receiving area 28, a conduit element 29, also referred to as a hose or water drain hose, is provided. The conduit element 29 is separate from the body 1, the support part 13, the flap unit 14, and the charging socket 3, and is fluidically connected to the receiving area 28. The conduit element 29 extends from the charging socket 3 on the rear side RS and passes through the drying chamber 27, thus terminating, for example, at its end opposite the receiving area 28, in an underfloor area of the body 1. This underfloor area is located, for example, in the vehicle's vertical direction, below the luggage compartment floor 22 and/or another floor of the body 1. This additional floor, for example, at least partially limits the interior space in the vehicle's vertical direction. It can be seen that the conduit element 29 allows water to be drained from the receiving area 28 and carried through the drying chamber 27 without passing water over sheet metal components. This prevents excessive corrosion.

Preferably, the support part 13, which is formed, for example, as a sheet metal component or from a metallic material, is used for a ground connection. For example, the support part 13 is also used to guide the conductor element 29.
