Description

Technical Field

[0001] The present disclosure relates generally to an interior system for a motor vehicle, and more particularly to flexibly configuring functional components of a vehicle interior of a motor vehicle. Background Art

[0002] Modern motor vehicles, such as cars and trucks, typically feature a variety of functional components within their interiors. These components, for example, provide air conditioning, multimedia functionality, mobile device connectivity, or serve as storage. These components are often integrated into and embedded within interior systems (e.g., the instrument panel, trim, center console, etc.). Consequently, a specific configuration of components is specified for a given vehicle. Customization or adaptation to technological developments, such as changes in connector types, media types, and screen specifications, can be desirable. The location of specific connectivity, memory, or multimedia functions is also often geographically fixed within the vehicle. Furthermore, the electrical architecture is typically unique to each vehicle model, adapting to a defined connectivity strategy before production begins.

Wherever possible, the same reference numerals will be used throughout the drawings to refer to the same or like parts. In the drawings, the depicted structural elements are not to scale and certain parts are enlarged relative to other parts for the purpose of emphasis and understanding.

[0013] As required, specific embodiments of the present disclosure are disclosed herein; however, it should be understood that the disclosed embodiments are merely examples of the present disclosure that can be embodied in various alternative forms. The drawings are not necessarily to detailed design; some diagrams may be exaggerated or minimized to provide an overview of the functionality. Therefore, the specific structural and functional details disclosed herein are not to be construed as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present disclosure.

However, it should be understood that the concepts may adopt different alternative orientations unless expressly specified otherwise. It should also be understood that the specific devices and processes illustrated in the drawings and described in the following specification are merely exemplary embodiments of the inventive concepts defined in the appended claims. Therefore, specific dimensions and other physical characteristics related to the embodiments disclosed herein should not be considered limiting unless the claims expressly provide otherwise.

[0015] The illustrative embodiments presented reside primarily in combinations of method steps and device components related to internal systems for motor vehicles. Accordingly, where appropriate, device components and method steps have been represented by conventional symbols in the drawings, with only those specific details relevant to understanding the embodiments of the present disclosure being shown so that the details, which would be apparent to one of ordinary skill in the art having the benefit of the description herein, do not obscure the present disclosure. Furthermore, like reference numerals in the specification and drawings represent like elements.

[0016] As used herein, the term "and / or" when used in conjunction with a list of two or more items means that any one of the listed items may be used alone, or any combination of two or more of the listed items may be used. For example, if a composition is described as comprising components A, B, and / or C, the composition may comprise only A; only B; only C; a combination of A and B; a combination of A and C; a combination of B and C; or a combination of A, B, and C.

[0017] In this document, relational terms such as first and second, top and bottom, etc., are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. The term "comprises," or any other variation thereof, is intended to cover a non-exclusive inclusion such that a process, method, article, or apparatus that includes a list of elements may include not only those elements but also other elements not expressly listed or inherent to such process, method, article, or apparatus. An element preceded by "comprises..." does not, without more constraints, preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the elements.

[0018] This application may refer to quantities and numbers. Unless expressly provided otherwise, such quantities and numbers should not be considered as limitations, but rather as examples of possible quantities or numbers in the context of this application. In this context, this application may also use the phrase "a plurality of" to refer to a quantity or number. In this context, the phrase "a plurality of" should be any number greater than one, such as two, three, four, five, etc. The terms "approximately," "approximately," "close to," etc., mean ±5% of a specified value.

[0019] As used herein, the terms "substantially," "substantially," and variations thereof are intended to indicate that a described feature is equal to or approximately equal to a value or description. For example, a "substantially flat" surface is intended to indicate that the surface is flat or approximately flat. Additionally, "substantially" is intended to indicate that two values ​​are equal or approximately equal. In some embodiments, "substantially" can mean values ​​that are within 10% of each other, such as within 5% of each other, or within 2% of each other.

[0020] As used herein, the terms "the," "a," or "an" mean "at least one" and should not be limited to "only one" unless otherwise indicated. Thus, for example, reference to "a component" includes embodiments having two or more such components unless the context clearly indicates otherwise.

[0021] Identical components are denoted by identical reference numerals in the figures and are therefore generally described only once.

[0022] Reference Figure 1 , shows a schematic top view of a motor vehicle 1 which is configured as a passenger car in one example. For better orientation, a longitudinal axis X pointing to the rear of the vehicle, a transverse axis Y and an upwardly pointing vertical axis Z are drawn in. The motor vehicle 1 has a driver's seat 2, a passenger seat 3 and a rear seat 4. Also shown are a driver's instrument panel 5, a passenger instrument panel 6, a front center tunnel section 7 and a rear center tunnel section 8. The elements mentioned partly (at least partly) belong to an interior structure 16 of an interior system 15 according to the present disclosure. The interior structure 16 at least partly delimits an interior space 9 of the motor vehicle 1, which interior structure 16 can be formed at least partly by elements of an interior trim (without reference numerals). The interior system 15 also has a plurality of module bases 20. In Figure 1 In the figure, one module base 20 is provided on the driver's instrument panel 5, two module bases 20 are provided on the passenger instrument panel 6, one module base 20 is provided on the front center tunnel section 7, one module base 20 is provided on the rear center tunnel section 8, and one module base 20 is provided on each of the seat backs of the driver's seat 2 and the passenger seat 3. The arrangement of the module bases 20 shown should be understood as an example, and it should be understood that other suitable locations may be selected. For example, a functional module 40 is shown connected to the module base 20 of the front center tunnel section 7.

[0023] Figure 2 The module base 20 and the functional module 40 are shown in a perspective view in a separated state. Figure 3 Shown is a side view. Module base 20 has a base trim 21, which can be made of plastic or a composite material, for example. Module base 20 has multiple base contact surfaces 22 extending parallel to contact plane A. A retaining portion 23 can also be seen, which includes a guide structure in the form of a base guide surface 24. This guide structure is oriented parallel to a guide axis F and defines a recess 25, the function of which will be explained below. Furthermore, a base connection structure 26, located in the area of ​​recess 25, connects to a terminal block 35. Terminal block 35 includes a power socket 36 and a data socket 37, to which a power plug 71 and a data plug 72 can be connected. The aforementioned power plug 71 and data plug 72 are connected to a power cable 73 and a data cable 74, respectively, and together form part of a transmission system 70. Instead of a single transmission system 70, we can also speak of a data transmission system on the one hand and an energy transmission system on the other. Using transmission system 70, base connection structure 26 is connected to vehicle battery 10 on the one hand and to vehicle control system 11 on the other. Furthermore, the base connection structure 26 may be connected to the base connection structure 26 of other module bases 20 for data transfer.

[0024] Functional module 40 comprises a module housing 41 , which can be made of, for example, a plastic or composite material, ideally with a coating or cover corresponding to base trim 21 . Various electronic components (not shown here) can be located within module housing 41 . Two external interfaces 55 (e.g., USB interfaces) are located on the exterior of module housing 41 . Furthermore, a wireless communication interface 56 , such as a Bluetooth interface, is located within module housing 41 , more specifically, within the main portion 42 of module housing 41 . A module contact surface 43 is formed on the main portion of module housing 41 . This module contact surface 43 corresponds to the base contact surface 22 and is also oriented parallel to contact plane A. Furthermore, a base portion 44 projects from main portion 42 . Base portion 44 accordingly has a connecting portion 45 directly adjacent to main portion 42 and adjacent flange portions 46 projecting from connecting portion 45 on either side. Guide structures in the form of modular guide surfaces 47 are formed on flange portion 46 . These guide structures also extend parallel to guide axis F and match the shape and geometry of base guide surface 24 . The flange portion 46 also has a modular connection structure 48. Figure 3 As can be seen in the figure, the contact plane A and the guide axis F extend at an angle to each other, in this example, approximately 20°. To connect the functional module 40 to the module base 20, the functional module 40 is aligned parallel to the guide axis, with the aforementioned guide surfaces 24 and 47 interacting to define the guide axis F. The base portion 44 is inserted into the aforementioned recess 25. Finally, the functional module 20 reaches a connected position, in which the base connection structure 26 and the module connection structure 48 are connected in a transmission manner. In this case, the base connection structure 26 and the module connection structure 48 are connected in an electrically conductive manner. The connected position can be defined by the fact that the retaining portion 23 forms a stop for the base portion 44 in the direction of the guide axis F. Furthermore, the connected position is defined by the retaining mechanism 53, which is formed by a resiliently deflectable locking element 54 on the base portion 44 and a corresponding locking recess 31 in the region of the base connection structure 26.

[0025] In particular, Figure 4 and Figure 6As can be seen in FIG, the module connection structure 48 has a power connection unit 49 on one hand and a data connection unit 51 on the other hand. The power connection unit 49 has a power contact 50, and the data connection unit 51 has a data contact 52. Correspondingly, the base connection structure 26 has a power connection unit 27 and a data connection unit 29. The power connection unit 27 has a power contact 28, and the data connection unit 29 has a data contact 30. The power contact 28 is connected to the power socket 36, while the data contact 30 is connected to the data socket 37. The contacts 50 and 52 of the module connection structure 48 protrude relative to the base portion 46 but are resiliently deflectable so that they can be embedded in the module housing 41. Meanwhile, the contacts 28 and 30 of the base connection structure 26 are recessed. When the functional module 40 has reached the connection position, the contacts 50 and 52 of the module connection structure 48 can engage with the contacts 28 and 30 of the base connection structure 26.

[0026] Although Figure 6 Show from Figure 2 and Figure 3 The bottom portion 44 of the functional module 40, but Figure 7 A corresponding illustration shows an alternative embodiment of the functional module 40 that does not require a data connection. Therefore, the data connection unit 51 is omitted and only the power connection unit 49 is shown. Figure 8 It is an illustration of a bottom portion 44 of a completely passive functional module 40 which also does not require a power supply, and therefore the entire module connection structure 48 is omitted.

[0027] Figure 9 A perspective view of the front center tunnel section 7 is shown, into the surface of which the base trim 21 of the module base 20 is integrated. Figure 10-15 Display according to Figure 9 , wherein the corresponding functional module 40 is connected to the module base 20 in the connected position. The base trim 21 is completely or partially covered by the module housing 41 relative to the interior space 9. In particular, the two connecting structures 26, 48 are completely hidden. Figure 10 Show referenced Figure 2 and Figure 3 The functional module 40 is described. Figure 11 A functional module 40 with a reading function for a data carrier (in this example, a music tape (not shown)) is shown. A cover 58 is attached to the module housing 41, shown here in the closed position. Furthermore, a plurality of control elements 57 are provided on the module housing 41, forming an input interface for the user. Analog data read from the music tape can be converted to digital data in the functional module 41 and subsequently transmitted via the data connection units 29 and 51. Figure 12An example of a purely passive functional module 40 in the form of a cover module is shown. This completely covers the base trim 21. The purely passive functional module 40 has a flat contour that protrudes as little as possible from the adjacent area of ​​the front center tunnel part 7. Figure 13 A functional module is shown which, in addition to two external interfaces 55, also has a plurality of control elements 57 as input interfaces for a user. By using these control elements 57 (shown here as buttons and a rotary controller), functions of an infotainment system, for example, can be controlled. Figure 14 The functional module 40 is shown in the form of a storage module, which delimits a storage space 59. Various objects can be stored in this storage space 59. Generally, a design as a passive functional module 40 is sufficient, but the integration of active functional components such as a wireless communication interface 52 is also conceivable.

[0028] Figure 15 A perspective view of the rear center tunnel section 8 is shown, into the surface of which the base trim 21 of the module base 20 is integrated. Figure 16-20 Each display is based on Figure 15 , in which the functional module 40 is connected to the module base 20 in the connected position, wherein the base trim 21 is at least partially covered by the module housing 41 relative to the interior 9 . Figure 16 Show referenced Figure 2 and Figure 3 The functional modules 40 are described. Figure 17 The functional module 40 is shown with two external interfaces 55 and a touch screen 60 , which represents both an input interface and an output interface. Figure 18 Display ratio Figure 17 A simplified, smaller and cheaper version, Figure 18 There are only two input elements 57 in the form of a rotary controller and a button. Figure 19 A functional module 40 is shown which, in addition to an external interface 55, also has a holder 61 for a smartphone. The smartphone can be connected to the infotainment system and also charged via the external interface 55. A wireless communication interface 56 can also be integrated into the functional module. Figure 20 The functional module 40 is shown again in a passive form, which serves only to cover the base trim 21 .

[0029] The present disclosure provides an interior system for a motor vehicle. The term "motor vehicle" herein, in a narrow sense, may refer to a road vehicle, i.e., a vehicle suitable for and registered for road traffic. Specifically, a motor vehicle may be a car, truck, or bus. The propulsion of the motor vehicle is not limited; for example, the motor vehicle may be powered by an internal combustion engine using gasoline, diesel, liquefied petroleum gas, hydrogen, or another gas as a fuel. Alternatively or in addition, an electric motor may be provided, for example, powered by a battery cell and / or fuel cell. Preferably, the motor vehicle has at least two axles, each with two wheels, but deviations from this are also contemplated. The term "interior system" refers to a system having at least two components intended for use in and associated with the interior of a motor vehicle. The interior may also be referred to as the passenger compartment and is the area intended to be occupied by occupants of the motor vehicle. With respect to the interior system, this may also include the front and / or rear areas of the motor vehicle, including the trunk and / or the trunk. The term "trunk" is composed of the terms "front" and "trunk." So the trunk refers to the luggage compartment under the hood, and in many electric vehicles there is space under the hood for an additional trunk.

[0030] The interior system comprises an interior structure which is at least partially adjacent to the vehicle interior. When assembled, the interior structure is part of the vehicle body and can in particular form a sprung mass. The interior structure (which can also be referred to as an interior component) can in particular be associated with the body of the motor vehicle. The interior structure is at least partially adjacent to the vehicle interior; it can also be said that the interior structure at least partially delimits the vehicle interior. In particular, the interior structure can include trim on the dashboard, center console, vehicle walls or doors, and can, for example, include parts of vehicle seats, such as armrests at the front and rear. In a broader sense, the interior structure can also be referred to as an interior trim structure, although the interior structure can have elements which, at least in the strict sense, are not part of the interior trim of the motor vehicle.

[0031] The interior structure comprises at least one module base, which includes a base trim, to which a base connection structure is connected. The base trim is associated with the vehicle's transmission system. The module base forms the base for the functional modules described below. The module base is part of the interior structure and, therefore, is preferably part of the vehicle body (particularly the bodywork). Unless deformed in shape, the module base is generally intended to remain permanently installed in a fixed position throughout the vehicle's service life. The base trim can be considered part of the vehicle's interior trim. The base trim may be directly adjacent to the vehicle interior, in whole or in part. Therefore, the base trim may have usable surfaces, at least in some areas, particularly those visible and tactile, by the vehicle's occupants. Typical materials for the base trim are, for example, plastic or composite materials. At least in some areas, the base trim may have a coating or covering to create a favorable appearance and / or feel. The base connection structure associated with the vehicle's transmission system is disposed on the base trim. At least in some embodiments, the transmission system may also be described as a distribution system. Thus, a transmission system may include conductors or wires for transmission and may be connected to the base connection structure for transmission. As will be explained below, the transmission system is primarily used for power and / or signal transmission. The base connection structure allows connection to the transmission system. At least some of the aforementioned conductors or wires can be considered part of the internal structure. Depending on your perspective, the base connection structure can also be said to belong to the transmission system, that is, to be part of the transmission system.

[0032] Furthermore, the internal system has at least one functional module, which has a module housing on which a module connection structure is arranged. The functional modules can have different functions, some of which will be discussed below. Preferably, the module housing closes the functional module from the outside and provides the functional module with mechanical stability. However, the term "housing" should not be interpreted as meaning that the module housing has to be closed. The module housing can protect the internal elements of the functional module from dust, deformation, moisture and / or other influences. The module connection structure is located on the module housing, wherein preferably, the position of the module connection structure or the position of individual components of the module connection structure on the module housing is fixed, possibly with limited mobility with a certain degree of freedom.

[0033] The corresponding functional module can be mechanically connected to the module base in a connected position such that the connecting structure is transmissively connected and the base trim is at least partially covered relative to the vehicle interior by the module housing, with the retaining mechanism in the locked position preventing the functional module from being separated from the module base. The connected position refers to the position of the functional module relative to the module base. In this position, a mechanical connection exists between the functional module and the module base. This preferably involves a positive fit between the functional module and the module base, which can be achieved directly or, if necessary, indirectly via an intermediate element. The aforementioned positive fit is ideally designed so that the functional module and the module base can be separated from each other non-destructively. The mechanical connection may also include a press fit. Due to the mechanical connection, the functional module is preferably fixed relative to the module base, with negligible displacement, and the mechanical connection also determines the connected position. In any case, in the connected position, the base connecting structure and the module connecting structure are transmissively connected, such that they are connected in a manner that allows transfer from one connecting structure to the other. This can involve transfer from the base connecting structure to the module connecting structure, and vice versa. In any case, the functional modules are connected to the transmission system. They are therefore connected to the relevant infrastructure of the motor vehicle. This enables the functional modules to perform their intended function, which may also be a combination of functions.

[0034] In the connected position, the base trim is at least partially covered by the module housing relative to the vehicle interior. This means that at least a portion of the base trim is no longer freely accessible from the vehicle interior. Preferably, at least a portion of the base trim is no longer visible. A gap between the module housing and the base trim is possible, but preferably, the width of the gap does not exceed 5 mm, 2 mm, or 1 mm. This means that the covered area of ​​the base trim cannot be touched by occupants. Preferably, the module housing rests on the base trim at least in sections. Obviously, the base connection structure is preferably located in the covered portion of the base trim. As a result, the two connection structures are somewhat isolated from the vehicle interior. Thus, the connection structures are at least partially protected from mechanical deformation, dirt accumulation, and other influences. Furthermore, the connection structures are invisible to occupants. Since the module housing covers at least a portion of the base trim in the manner described, it accordingly forms part of the interior of the motor vehicle. In particular, since the connection structures are invisible to occupants, the functional module is ideally perceived by them as an integral part of the motor vehicle.

[0035] In the locked position, the retaining mechanism prevents the functional module from being separated from the module base. This means that when the retaining mechanism is in the locked position, the retaining mechanism prevents the functional module from being separated from the module base. The retaining mechanism can be fully or partially integrated into the module base and / or into the functional module. However, the retaining mechanism can also be formed at least partially by another element. In particular, the retaining mechanism can directly form a form fit between the functional module and the module base, but if necessary, a force connection, or indirectly form a form fit between the functional module and the module base, but if necessary, a force connection, for example, via at least one intermediate element. At least in the case of a form fit, the retaining mechanism will also prevent the functional module from being brought into the connection position when in the locked position. Therefore, the retaining mechanism is preferably adjustable between a locked position and an unlocked position. When the retaining mechanism is in the unlocked position, the functional module can be separated from the module base. Of course, this refers to non-destructive separation, in particular tool-free separation.

[0036] The interior system according to the present disclosure enables a flexible design in which functional modules can be optionally integrated. In the connected state, for example in the connected position, the functional module can be regarded as an integral part of the motor vehicle, wherein the module housing forms part of the interior at least as seen by the occupants. In the connected position, the functional module is mechanically connected to the module base and is protected against unintentional or possibly unauthorized movement of the functional module by a retaining mechanism. Since the functional module with the module housing at least partially covers the base trim, a part of the module housing and at least a part of the base cover are protected from mechanical and dust influences at least to a certain extent. As already mentioned above, this area is where the connecting structure is preferably located, which helps to maintain the functionality.

[0037] The advantages of the interior system's modular design can be enhanced through additional combination options. According to one embodiment, the interior system includes a plurality of different functional modules that can be optionally connected to a module base. This means that the different functional modules and the module base are matched to each other in such a way that a functional module can be selected and connected to the module base. In this way, different functional modules, and therefore different functions, can be optionally provided at the same location in the motor vehicle. Functional modules can be interchanged not only for variants but also to implement different (especially more modern) technical standards, for example, to provide different functions or similar functions. It goes without saying that different functions can also be provided for the initial equipment of the motor vehicle according to customer requirements.

[0038] Another embodiment, particularly useful in combination with the aforementioned embodiment, provides an interior structure having multiple module bases, wherein at least one functional module can be selectively connected to different module bases. For example, one module base could be located on the dashboard in the passenger area, another on the center console, a third at the rear end of the center tunnel, and a fourth on the seatback of the driver's seat, passenger seat, or the like. This means that the module base can be selected for the same functional module. Thus, it is possible to selectively determine where a certain function should be accessible.

[0039] According to one embodiment, at least one connection structure has a data connection unit for data transmission. The transmission system is therefore also configured for data transmission. The data transmission unit can have one or more electrical contacts which, in the connected position, can be in conductive contact with corresponding contacts of the data connection unit of the other connection structure. Although conductive contact is preferred, electrical signals can also be transmitted contactlessly (e.g. inductively and / or capacitively). However, in addition to electrical data transmission, another transmission principle can also be used. For example, optical transmission is conceivable, using which light pulses from the transmission system are connected to the functional module via the base connection structure and the module connection structure. Of course, the reverse transmission path is also possible. Preferably, the term "data transmission" here and below refers to digital data transmission, but also covers the transmission of analog signals.

[0040] As an alternative to or in addition to the data connection unit, at least one connection structure can advantageously include a power connection unit for power transmission. Preferably, such a power connection unit has at least two electrical contacts, which can be described as "phase" and "ground," for example. Contacts at ground potential or reference potential can be associated with the power connection unit and with the additional data connection unit. However, power transmission can also be contactless, for example, inductive and / or capacitive. In this case, the power connection unit is configured for corresponding contactless transmission.

[0041] In one embodiment, it is particularly preferred that at least one base connection structure has a data connection unit and a power connection unit. The module connection structure of the connected functional module may also have a data connection unit and a power connection unit. However, it is also conceivable that the functional module is not configured for any data transmission and therefore only has a power connection unit. Thus, although there is no data connection unit connected to the module base, the two power connection units will be connected in a transmission manner.

[0042] Within the context of this disclosure, there are essentially no restrictions regarding the functional modules that can be provided for a function. Specifically, at least one functional module may include an input interface and / or an output interface for a user, a read function for a mobile data carrier, an external interface, a charging socket, and / or a wireless communication interface. The input interface may include at least one switch, button, or controller, and at least one sensor, which may be in the form of a capacitive sensor, such as an optical sensor unit such as a camera, or an acoustic sensor such as a microphone. On the one hand, the functions of the functional module can be controlled via the input interface, and on the other hand, signals can be transmitted to other components of the motor vehicle via a data connection unit, thereby enabling signal control using the functional module. For example, the output interface may be designed for light output and may include at least one LED, a seven-segment display, or a screen. The screen may be in the form of a touchscreen and thus simultaneously serve as an input interface. The output interface may also be configured for sound output, for example, as a loudspeaker. Tactile output interfaces, such as Braille displays, are also conceivable. The output interface may also be used to output information related solely to the functional module itself or information transmitted from other vehicle components via a transmission system and a corresponding data connection unit. Of course, multiple input and / or output interfaces may be combined within a functional module. The function for reading removable data media can be used with a variety of data media, such as USB flash drives, memory cards, CDs (Compact Discs), and music cassettes. This means that both digital and analog data can be read. The read data can be output by the function module itself or transmitted via a data connection unit and transmission system to other vehicle components, such as the multimedia system, where it can then be output. It is also conceivable that the data is not output but used within the vehicle. The function module may also have an external interface and / or a charging socket for connecting external devices, including a battery charger. For example, the external interface may be a USB port or a headphone output, or it may be a connection for speakers, where the vehicle's multimedia system can be connected to one or more sound output devices. The charging socket is used to connect external devices, either via a charging cable or directly. The charging socket can provide DC voltage, but it can also provide AC voltage. If necessary, a rectifier, inverter, or other components for voltage regulation can be integrated into the function module. It is understood that the functions of the charging socket and the external interface can be integrated into a single interface, such as a USB port. Wireless interfaces may be provided for different types of communication, such as Bluetooth, WLAN (Wireless Local Area Network), NFC (Near Field Communication) or infrared.While ideally, each functional module would be connectable to any module dock, it makes sense for such functional modules to be used in the trunk and / or the rear trunk within the context of the present disclosure, where the desired functionality is enabled. It is advantageous to use the vehicle data readout module for service purposes or to provide a connection option for external consumers and / or audio reproduction devices, such as those connected to the vehicle's multimedia system and / or energy storage system. External multimedia systems can also be connected to the vehicle via corresponding functional modules.

[0043] As explained above, the connection structures of the module base and the functional module do not have to match. For example, the base connection structure may have both a power connection unit and a data connection unit, while the connected functional module only has a power connection unit. If the module base does not require "active" functions, the functional module can be omitted. However, the base connection structure will be accessible and visible from the vehicle interior. Therefore, it is advantageous to design at least one functional module passively as a cover module to at least partially cover the base trim. Preferably, the cover module can be connected to the active functional module in a similar manner and secured by the retaining mechanism described above. The cover module differs from the active functional module in that it does not have a module connection structure. The module housing of the cover module can be very simple, as it only serves to fully or partially cover the base trim and may create a visually and / or tactilely attractive surface in certain areas. The functional module can also take the form of a storage module with a partially enclosed storage space. The storage module can form a box or bowl, with an optional cover. In a broader sense, a holder for an external device such as a smartphone or tablet is also considered a storage module in this context. The storage module can also be a passive form factor without module connection structures. However, it is also possible to integrate active functions. For example, an external interface and / or a charging socket can be integrated. The device contained in the storage module can be connected to the external interface and / or charging socket.

[0044] A design provides that at least one module base and at least one functional module have interacting guide structures, by which the functional module can be moved along a guide axis on the module base into a connection position. For example, the guide structure can be in the form of a guide surface, a guide rod, a guide rail or a guide groove. On the one hand, the guide structure of the module base and on the other hand, the shape and size of the functional module are matched to each other in such a way that they form a partial form fit, but the partial form fit allows displacement along the guide axis. Appropriate guidance makes it easier to connect the functional modules, which helps to ensure that even users with insufficient technical experience can do so. Advantageously, the module base and the functional module may also have interacting limiter structures, which define the connection position. By using a form fit, the limiter structure prevents the functional module from being pushed out of the connection position. However, to some extent, if the retaining mechanism automatically defines the connection position, such a limiter structure may be dispensable in some cases.

[0045] According to one design, for example, the module connection structure can be arranged at the end or front side relative to the guide axis. In this case, a portion of the module housing is pushed into a connection position in front of the module connection structure, where it encounters the base connection structure opposite it along the guide axis. Another advantageous design provides that at least one connection structure is located on a surface extending parallel to the guide axis. This means that the connection structure is positioned laterally with respect to the direction of movement predetermined by the guide axis. It is possible that at least parts of the corresponding connection structure can be elastically deflected transversely to the guide axis. This means that they can be deflected against an elastic restoring force and, in particular, at least partially embed into the surrounding module housing or into the surrounding base trim. For example, corresponding parts of other connection structures can define a groove extending transversely to the guide axis, into which the elastically deflectable part can engage when the connection position is reached. Due to the elastic deflection, the contact between the connection structures can generally be secured or strengthened by the elastic restoring force. The surface on which the connection structure is located can be in the form of a guide surface, thereby forming the aforementioned guide structure.

[0046] Advantageously, the retaining mechanism includes an elastically deflectable locking element that engages in a positively locking recess in the locked position. The locking element can be provided on the functional module or on the module base. Accordingly, the locking recess is provided on the module base or on the functional module. Preferably, in one example, the locking element is elastically deflectable transversely to the guide axis. According to one embodiment, the locking element is provided in the region of the connecting structure. The corresponding locking element can be used to precisely define the connection position. On the one hand, this ensures a transmissive connection between the connecting structures, and on the other hand, the user receives a tactile signal and, if appropriate, an acoustic signal, which allows the user to recognize that the connection position has been reached. To adjust the retaining mechanism from the locked position to the unlocked position, and vice versa, in one embodiment, an actuator is provided on the functional module and / or on the module base. This actuator can be mechanical and / or electrical, such as a lever or button that acts on the retaining mechanism (e.g., the elastically deflectable locking element) to lock or release it. In particular, if the locking element is engaged with the locking recess, it is necessary to move the locking element out of the locking recess, which is achieved by means of an actuator. This actuator can also act on the elastically deflectable parts of the connecting structure in such a way that they are also moved out of the corresponding recess when the retaining mechanism is adjusted to the release position.

[0047] One design provides a module housing comprising a main portion and a bottom portion protruding from the main portion at an angle relative to a guide axis. A module connection structure is located on the bottom portion, and a base trim has a retaining portion that forms a positive fit with the bottom portion transverse to the guide axis. The main portion is typically larger than the bottom portion, although these designations should not be construed restrictively. Most of the functional components of the functional module can be located in the main portion, while the bottom portion is used entirely or primarily to establish the connection with the base module. The base trim itself has a retaining portion shaped so that it forms a positive fit with the bottom portion, at least in the connected position. In particular, the aforementioned guide structure can be formed at least partially on the bottom portion and on the retaining portion, particularly as a guide surface. To achieve this positive fit, the bottom portion can, for example, have an L-shaped or T-shaped cross-section, with a connecting portion adjacent to the main portion and a flange portion extending from one or both sides of the connecting portion. The module connection structure can be located on the flange portion. For example, to interact with the T-shaped cross-section, the retaining portion can have a C-shaped cross-section, at least in sections. The bottom portion and the holding portion may also have a stopper structure, and the connection position is defined by the stopper structure.

[0048] Preferably, the module housing and the base trim have contact surfaces that are adjacent to each other in the connected position. This means that the aforementioned contact surfaces are adjacent to each other and therefore contact each other when the functional module is in the connected position. Due to this contact, the module housing and the base trim are connected to each other without gaps, at least in this area, which, for example, improves the protection of the connection structure. Furthermore, forces or moments acting on the functional module can be transmitted to the module base via the contact surfaces, which improves the stability of the connection. As mentioned above, if a guide axis is defined, it is conceivable, for example, that the contact surfaces are oriented perpendicular to or parallel to the guide axis. According to a preferred design, the contact surfaces extend at least partially parallel to a contact plane, which extends at an angle to the guide axis. According to an example, the angle between the contact plane and the guide axis can preferably be between 5° and 61°, more preferably between 10° and 40°. Due to the tilted structure, when the functional module is moved into the connected position, the contact surfaces are directed toward each other at an angle to their contact planes relative to the guide axis.

[0049] It will be understood that changes and modifications can be made to the above-described structures without departing from the spirit of the present disclosure, and it will be further understood that such spirits are intended to be covered by the following claims unless such claims expressly dictate otherwise in their language.
