[0001] MODULAR ASSEMBLY FOR A CARGO COMPARTMENT OF A MOTOR VEHICLE AND METHOD FOR ASSEMBLY

[0002] Description

[0003] The proposed solution relates to a modular assembly for a loading space, in particular a frunk, of a motor vehicle.

[0004] Such a module assembly has at least one base body which is designed to provide storage space.

[0005] While conventional motor vehicles typically have a cargo space in the rear of the vehicle where cargo can be stowed, modern vehicle concepts, especially electrically powered vehicles (so-called electric vehicles), can also accommodate free space in the front of the vehicle (because no space is required for an internal combustion engine there), thus creating additional cargo space at the front of the vehicle. A cargo space located at the front of a motor vehicle is also referred to as a frunk (combined from the English terms "front" and "trunk").

[0006] It may be desirable to line the cargo area of ​​the motor vehicle with at least one base body to provide protection against moisture and a well-defined storage space for neatly storing items to be transported in the cargo area. Typically, the at least one base body is inserted into the cargo area and secured there.

[0007] Against this background, there is a need to also accommodate functional assemblies in the cargo space.

[0008] The objective of the proposed solution is to provide a modular assembly for a cargo space of a motor vehicle that is easy to assemble.

[0009] According to a first aspect of the proposed solution, this object is achieved by an article having the features of claim 1.

[0010] Accordingly, the at least one base body has at least one mounting section on which at least one functional module is mounted. The at least one functional module can be mounted on one, two or more mounting sections. Likewise, one, two or more functional assemblies can be mounted on one mounting section. In principle, any number of functional assemblies can be mounted on the base body via respectively assigned mounting sections. Because the at least one functional module is mounted on the base body, the at least one functional module can be mounted together (as a whole) with the base body in the cargo space of the motor vehicle (so-called "one-piece" assembly). This can significantly simplify assembly and fewer individual parts need to be moved for assembly.

[0011] The module assembly can be fed to a manufacturing process of the motor vehicle in a pre-assembly state in which the at least one functional assembly is arranged on the at least one base body. For example, in the pre-assembly state, the at least one functional assembly can be arranged loosely and / or with a non-final fastening force on the base body. After the module assembly has been arranged in the cargo space, final assembly of the at least one functional assembly on the base body can be carried out, via which final assembly state the at least one functional assembly is transferred to a final assembly state. The final assembly can, for example, comprise a play-free fastening of the at least one functional assembly and / or the establishment of a final fastening force on the base body. This allows final assembly to take place more quickly, which, for example, speeds up line assembly during the manufacturing process of the motor vehicle.The at least one assembly section can, for example, be designed and provided to provide the pre-assembly state (for a loose and / or non-final arrangement of the at least one functional assembly on the at least one base body) and the final assembly state (for a more secure and / or play-free arrangement of the at least one functional assembly on the at least one base body). In the final assembly state, the at least one functional assembly can have a fastening to the at least one base body that can withstand stronger tensile forces than a fastening in the pre-assembly state. Tensile forces can act to separate the at least one functional assembly from the at least one base body. Thus, tensile forces load a fastening of the at least one functional assembly to the at least one base body.If a fastening force of the at least one functional assembly on the at least one base body is exceeded, the at least one functional assembly tears off from the base body.

[0012] For example, it is conceivable and possible to exploit the pre-assembly state during the manufacture of the motor vehicle in such a way that tolerances between the module assembly and the loading space can be compensated (because the fastening is less strong) before at least one functional assembly is transferred to the final assembly state.

[0013] In one embodiment, the at least one assembly section has a first fastening section for pre-assembly of the at least one functional module and a second fastening section for final assembly of the at least one functional module. In principle, the at least one functional module can be mounted on the at least one assembly section on a single fastening section for pre-assembly and optionally transferred from this pre-assembly state to the final assembly state at a later point in time. For example, corresponding assembly with a screw connection that is loosely screwed in the pre-assembly state and tightened in the final assembly state is conceivable and possible. The provision of two (or more) fastening sections can enable a different design of the fastening sections, tailored to the respective requirements of the pre-assembly and final assembly states.

[0014] In one embodiment, the first fastening section provides a different type of fastening than the second fastening section. Alternatively or additionally, a lower fastening force can be transmitted via the first fastening section than via the second fastening section. For example, the first fastening section can be designed such that a quick and precise fastening of the at least one functional assembly to the mounting section is possible, but can withstand less great tensile forces (because this is not absolutely necessary during pre-assembly). The second fastening section can be designed such that it offers a fastening option that can withstand higher tensile forces.

[0015] Such a design of the fastening sections can be achieved by providing different types of fastening. The fastening types can also be used to design the fastening sections for different fastening forces. The fastening force that can be transmitted via the fastening sections can counteract the tensile force that can cause the separation of the at least one functional assembly from the at least one base body. The fastening force can therefore define the strength of the fastening. In principle, the transmission of different fastening forces via the fastening sections can also be achieved with the same types of fastening.

[0016] In one embodiment, the mounting section provides at least one positive and / or non-positive fastening. Such fastening options can enable fast, precise, and secure assembly. For example, the at least one functional module can be latched or clipped to the mounting section for assembly.

[0017] In the case of an assembly section with fastening sections, the first fastening section can provide at least one positive fastening. Alternatively or additionally, the second fastening section can provide at least one force-locking fastening. The positive fastening and the force-locking fastening are examples of different types of fastening. The at least one positive fastening can be used to quickly, precisely, and securely fix the at least one functional assembly to the base body. The at least one force-locking fastening can optionally be combined with a positive fastening. With the at least one force-locking fastening, a high fastening force can be transmitted via the second fastening section.The first fastening section can provide at least one clip, latch, and / or bayonet connection (positive fastening). Alternatively or additionally, the second fastening section can provide at least one screw connection (a combination of force-locking and positive fastening).

[0018] In one embodiment, the at least one base body has at least one additional recess in which the at least one functional module is arranged. The at least one additional recess (e.g. in the form of a drawer for the at least one functional module) can be provided in addition to the storage space on the at least one base body. For example, the storage space can have an opening in an opening plane that is arranged parallel to another opening plane of the at least one additional recess. Objects can be introduced into the storage space through the opening. The at least one additional recess can alternatively or additionally be arranged on an edging element by means of which the interior of the storage space is separated from an exterior of the storage space. For this purpose, the edging element can, for example, protrude into the storage space.

[0019] The surround element can protrude from a floor element of the base body. For example, the at least one additional recess can be arranged in a section of the surround element that is located rearward in the direction of travel during the intended use of the module assembly on a motor vehicle. The surround element can partially protrude into the storage space at this section. This can, for example, create additional installation space for a heating, ventilation, and / or air conditioning unit of the motor vehicle, which can be provided in a dashboard of the interior of the motor vehicle.

[0020] In a further variant, the at least one additional recess can be formed on a base element of the at least one base body, which delimits the storage space on a side of the base body opposite the opening of the storage space. The opening and the base element can generally be spaced apart by the edging element.

[0021] In one embodiment, the at least one additional recess is designed such that the at least one functional assembly can be received therein in a watertight manner. In particular, the watertight design can prevent liquids from the at least one functional assembly from penetrating the storage space or liquids that could damage the at least one functional assembly from penetrating the at least one additional recess. For example, the at least one additional recess can have a recess opening that is delimited by a sealing edge.

[0022] In one embodiment, the at least one base body has at least a first and at least one second mounting section, on each of which a functional assembly is arranged, wherein the at least two functional assemblies are coupled to one another via at least one flexible transmission means. The at least one flexible transmission means can, for example, comprise a Bowden cable, a data cable and / or an electrical power cable. In this way, the at least one flexible transmission means can be tested for proper function before the module assembly is mounted on the motor vehicle, in particular in the pre-assembly state. This can also save time, in particular, during the manufacture of a motor vehicle with the module assembly.

[0023] The at least one flexible transmission means can, for example, be guided at least in sections along an edge element that protrudes from the enclosure element of the base body (in particular transversely thereto and / or outwardly relative to the storage space). The at least one flexible transmission means can be arranged on the enclosure element on the side of the base element (i.e., below) the edge element. This arrangement can conceal it from a user of the module assembly who is looking at the storage space from the opening side (from above).

[0024] In one embodiment, at least one holding element is provided on the at least one base body, on which holding element the at least one flexible transmission means is held for guidance on the at least one base body. The at least one flexible transmission means then does not need to be attached to the at least one base body during manufacture of the motor vehicle. Rather, the module assembly with the at least one base body, the at least two functional units and the at least one flexible transmission means can be made available before assembly on the motor vehicle, in particular in a pre-assembly state, in which the module assembly only needs to be arranged on the motor vehicle as a whole and, if necessary, brought into the final assembly state. In principle, any number of holding elements can be provided, on which the at least one flexible transmission means is held on the at least one base body.Preferably, the at least one holding element can be arranged on the edging element of the at least one base body adjacent to an edge element of the at least one base body which is formed transversely to the edging element.

[0025] In one embodiment, the at least one functional assembly comprises a control device, a liquid container device, an adjustment assembly, a locking assembly, a closing aid, a collar for the at least one base body (in particular also for more than one base body), an emergency release lever, an emergency call device, and / or at least one loudspeaker. Alternatively or additionally, the at least one functional assembly can comprise a contact plug, a drain plug, a membrane, a seal, a component of an air conditioning device such as an air guide element, an electronic access module with which access to the storage space can be controlled, and / or an HMI (human-machine interface) system.

[0026] Accordingly, the at least one functional module can generally be configured and provided to provide at least one function for the use of the motor vehicle. In particular, this can be a function related to the frunk. A user can trigger the at least one function, for example, via an actuating element of the at least one functional module. The at least one functional module can comprise at least one electronic component.

[0027] The control device may, for example, comprise an electronic control unit (e.g., an ECU). In particular, this may be configured and provided to control other functional components of the module assembly.

[0028] The liquid container device can, for example, be provided for holding a liquid for cleaning a motor vehicle window.

[0029] The adjustment assembly can be configured and provided for adjusting a hood element relative to the module assembly. The hood element can, for example, serve to cover an opening in the cargo space in which the module group is arranged in the motor vehicle. The adjustment assembly can have a mounting base, via which the adjustment assembly can be arranged on the base body, and a hood holder that can be pivoted relative to the mounting base of the adjustment assembly. The mounting base can also have a locking element with which the pivoting of the hood holder relative to the mounting base can be blocked. Additionally or alternatively, the adjustment assembly can be provided for adjusting an adjustment element. The adjustment element can be provided for closing an access opening to the cargo space, through which an object can be introduced into the cargo space for storage on the floor element.In particular, the adjustment element can be provided in addition to the hood element. When the module assembly is arranged as intended on the motor vehicle, the adjustment element can be arranged on a front section of the motor vehicle (in front of the hood element in the direction of travel). The adjustment assembly can have an adjustment component such as an adjustment drive and / or a tension element that is arranged on the base body and acts on the adjustment element (e.g. via an adjustment arm that is arranged on the adjustment element). The adjustment drive can, for example, have a spindle drive and a spindle element that is adjustable with the spindle drive. The adjustment drive can be used to adjust the adjustment element relative to the base body.

[0030] The base body can have at least one support element to reinforce an area where the adjustment component engages the base body. The at least one support element can, for example, comprise a reinforcing rib. The area where the adjustment component engages the base body can be arranged close to an edge element of the base body. The base body can be mounted to the motor vehicle via the edge element. For example, the edge element can have screwing points via which the base body can be screwed to the motor vehicle. The edge element can be formed parallel to a floor element of the base body. It can protrude outwards from an edge element of the base body. An arrangement of the area where the adjustment component engages the base body close to the edge element can, for example, comprise an arrangement within a distance of 10 cm, 5 cm, or 2 cm.The at least one support element can be adjacent to the edge element. In particular, the at least one support element can be arranged on a border element of the base body that protrudes from the base element.

[0031] The locking assembly can be designed and provided for locking a cover element to the floor element or for locking the module assembly to the loading space.

[0032] The closing aid can be designed and provided to pull the hood element toward the module assembly to close the opening of the cargo space, thus allowing a user to more conveniently close the opening of the storage space. For this purpose, the closing aid can be arranged on an outer side of the base body, outside the storage space.

[0033] The emergency release lever can be located on the base body inside the storage compartment. The emergency release lever can be used to open the hood element from inside the storage compartment to release the opening of the storage compartment.

[0034] The emergency call device can be arranged inside the storage compartment on the at least one base body. The emergency call device can be used to generate an emergency call signal from inside the storage compartment, for example, by pressing a button, as described in German patent application 10 2023 121 784.

[0035] The at least one loudspeaker can, for example, comprise a vehicle warning sound generator (e.g., in the form of an Acoustic Vehicle Alerting System (AVAS) or a Horn Acoustic Vehicle Alerting System (HAVAS)) and / or at least one piezo actuator. The at least one loudspeaker can be arranged in a recess or on a flat section of the base body (e.g., on a section of the surround element), wherein the flat section is optionally used by the at least one loudspeaker to generate sound.

[0036] The HMI system can comprise at least one HMI module with a lighting device and / or a sensor device. The lighting device can, for example, comprise at least one LED. The sensor device can, for example, comprise at least one capacitive sensor and / or a radar sensor. The lighting device can, for example, display a status of the module assembly to the user of the module assembly. For example, the lighting device can have a first lighting mode that represents the successful triggering of an opening process of the hood element (for example, by a gesture and / or by a key device such as a car key), and a second lighting mode that represents that the hood element is in the open position.

[0037] The sensor device can trigger access to the storage space. For example, the sensor device can trigger the opening of the hood element. For this purpose, the sensor device can be configured and provided, for example, to detect a gesture by the user of the module assembly. In particular, the sensor device can be configured and provided to detect an upward hand movement as a signal to release the storage space (for example, by lifting the hood element).

[0038] The HMI system can, for example, have three HMI modules, with one HMI module being arranged on a side of the module assembly that is at the front in the direction of travel, and two further HMI modules being arranged on the two sides of the module assembly that are arranged laterally in the direction of travel (left and right of the motor vehicle when the module assembly is properly installed). A user of the module assembly can thus use the HMI system from the front of the motor vehicle and from the side of the motor vehicle. In particular, if the front of the motor vehicle is inaccessible, for example due to tight parking spaces, the presence of at least one laterally arranged HMI module can be advantageous.

[0039] In principle, a plurality of functional assemblies can be provided, with one or more functional assemblies each being provided in the form of the control device, the liquid container device, the adjustment assembly, the locking assembly, the closing aid, the contact plug, the drain plug, the membrane, the seal, the at least one component of the air conditioning device, the electronic access module, the HMI system, the emergency release lever, and / or the emergency call device. For example, it is conceivable and possible to provide two adjustment assemblies at spaced-apart mounting sections.

[0040] In one embodiment, the at least one base body is made of plastic. Alternatively or additionally, the at least one base body is designed such that it can be inserted into a similarly constructed base body for stacking and is at least partially retractable.

[0041] In principle, the at least one base body can be made of more than 90% plastic. Constructing the at least one base body from plastic can enable simple assembly because the at least one base body is then easy to handle and inexpensive to manufacture. The at least one base body can, for example, be tub-shaped. A tub-shaped design can be realized, for example, using a base element and a surround element of the base body, with the surround element protruding from the base element and thus at least partially enclosing the storage space.

[0042] The floor element can have a smaller area than a cross-section through the enclosure arranged parallel to the floor element. This means that the at least one base body can be conical, for example. This design can enable the at least one base body to be at least partially recessed into a base body of the same construction. Such a design of the at least one base body can save transport volume when transporting more than one module assembly.

[0043] The functional assembly can have at least one wall element. The storage space can be divided into two sub-spaces using the at least one wall element. At least one mounting section for the at least one wall element can be provided on the edging element, via which mounting section the at least one wall element is mounted in its intended position. The at least one mounting section for the at least one wall element can be designed, for example, as a guide track. The guide track can extend from the opening through which the storage space is accessible to the floor element. The guide track can be designed such that the at least one wall element can be inserted into the guide track. This can be achieved, for example, by a groove-like guide track.

[0044] The floor element can be covered by at least one cover element. The at least one cover element can be held in position (positively) by the at least one wall element. For example, the at least one wall element can rest on the at least one cover element.

[0045] The at least one cover element can be provided to form a gap between itself and the base element. At least one functional assembly can be arranged in the gap. The at least one functional assembly can be mounted on the base element.

[0046] The at least one base body can have a connecting section that protrudes from the floor element on a side of the floor element facing away from the edging element. The connecting section can protrude from the floor element parallel to the edging element. In particular, the connecting section can form a uniform surface with the edging element, at least partially outwardly. The connecting section can be designed and provided to connect at least one component of an air conditioning device to another component of the air conditioning device. For example, the connecting section can be designed and provided to connect at least one fan to at least one cooling component. Air can be exchanged between the at least two air conditioning components via the connection provided by the connecting section.In particular, the connecting section can thus provide an air duct. The air conditioning device can comprise a heating component in addition to or as an alternative to the cooling component. The heating component can optionally be supplied with air via the connecting section by the at least one fan, in addition to the at least one cooling component.

[0047] In one embodiment, the at least one functional assembly has a mounting base, via which the at least one functional assembly is coupled via at least one coupling element to at least one counter-element arranged on the mounting section. The at least one coupling element can serve to couple the at least one functional assembly to the at least one base body. For this purpose, the at least one functional assembly can have the mounting base and the at least one base body can have the at least one counter-element. The mounting base and the at least one counter-element can be designed to make assembly as precise and fast as possible and to enable secure coupling. The at least one coupling element can be configured and provided in such a way that it dampens the transmission of vibrations between the at least one functional assembly and the mounting section.For example, the at least one coupling element can be made of an elastic material (e.g., plastic or rubber). This can generally improve the shock resistance of the module assembly.

[0048] In principle, the coupling between the at least one coupling element and the mounting base and / or between the at least one coupling element and the at least one counter element can be established via a force-locking and / or form-locking connection.

[0049] In one embodiment, the at least one coupling element is coupled to the mounting base and / or the at least one counter-element is coupled to the mounting section via at least one fastening means. The at least one fastening means can be a screw, for example. By coupling the at least one counter-element to the mounting section via the at least one fastening means, the coupling can be loosely established in the pre-assembly state and reinforced for the final assembly state. Likewise, the mounting base can initially be loosely coupled to the at least one coupling element in the pre-assembly state, and the coupling can be reinforced to a desired degree in the final assembly state.

[0050] According to a second aspect of the proposed solution, the problem is solved by a method for assembling a modular assembly for a cargo space of a motor vehicle. The method comprises the following steps:

[0051] - Providing at least one base body with at least one assembly section,

[0052] - Pre-assembly of at least one functional assembly on the at least one assembly section to form the module assembly, and

[0053] - Arranging the module assembly on the motor vehicle.

[0054] Optionally, the next step can include final assembly of the functional assembly to the at least one assembly section. However, this is not mandatory, as the at least one functional assembly can potentially be secured to the at least one assembly section with sufficient strength during pre-assembly.

[0055] The pre-assembly and the final assembly can each include a fastening step with which the at least one functional assembly is fastened to the at least one assembly section. In particular, the method can be designed to include the following steps:

[0056] - Providing at least one base body with at least one

[0057] assembly section,

[0058] - Pre-assembly of at least one functional module on a first

[0059] Fastening section of at least one mounting section for forming the module assembly,

[0060] - Arranging the module assembly on the motor vehicle, and

[0061] - Final assembly of the at least one functional assembly on a second fastening section of the at least one mounting section. Features and advantages described in connection with the first aspect of the proposed solution can also apply to the method according to the second aspect.

[0062] The proposed solution also relates to a motor vehicle comprising a modular assembly according to the first aspect.

[0063] The idea underlying the proposed solution will be explained in more detail below using the exemplary embodiments shown in the figures. They show:

[0084] basic body.

[0085] Figure 1 shows a schematic view of a motor vehicle 1 having a frunk arranged in a front region of the motor vehicle 1, which can be closed by a hood element 12 and is divided into two storage compartments 11 and 11a. The storage compartments 11, 11a are each formed by a trough-shaped base body 2, 2a of a module assembly. The module assembly also has a collar 8 with a loading sill protection, on which, for example, heavy objects can be placed without damaging the motor vehicle 1 and / or the module assembly.

[0086] Figure 2A shows an exploded view of the module assembly with two trough-shaped base bodies 2, 2a, and Figure 2B shows another view of the same module assembly. A first trough-shaped base body 2 has a base element 20, from which a border element 22 protrudes to form, together with the base element 20, a first storage space 11. The base element 20 can be covered with a cover element 21 to protect the base element 20. A second trough-shaped base body 2a forms a second storage space 11a. The second base body 2a can be covered with a closure element 13 in addition to the hood element 12. The module assembly also has several further base bodies 2b, which in the present example are provided for accommodating functional assemblies (e.g., liquid container devices 4).

[0087] A collar 8 is arranged at an access opening to the storage compartments 11, 11a, 11b. The collar 8 has a loading sill protection element 81 to stabilize the collar 8 against heavy objects that can be placed thereon when the frunk is in use. Recesses are also provided on the collar 8 to allow access to the liquid container devices 4. The collar 8 can, in principle, provide a flat component that provides one or more recesses for access to at least one storage compartment 11, 11a, 11b and / or at least one functional assembly 4.

[0088] The module assembly has an HMI system 98 comprising two HMI modules 98a, 98b. The HMI modules 98a, 98b each have a lighting device with which a status of the module assembly can be displayed to a user. In addition, the HMI modules 98a, 98b each have a sensor device via which the user can operate the module assembly, for example, using gestures detectable by the sensor device. A first HMI module 98a is arranged on a side of the module assembly that is located at the front in the direction of travel. For example, the user can operate the first HMI module 98a when standing in front of the motor vehicle. For example, the first HMI module 98a can be configured and provided to trigger an opening of the hood element 12 by an upward movement of a hand by the user. A second HMI module 98b is arranged on a side of the module assembly that is arranged on the side of the motor vehicle 1.The user can operate the second HMI module 98b when standing to the side of the motor vehicle 1. For example, the second HMI module 98b can be configured and designed to trigger an opening of the hood element 12 through a swiping movement of the user's hand. In principle, the HMI system 98 can have any number of HMI modules 98a, 98b arranged on the sides or on a front section of the module assembly. The HMI system 98 can be configured and designed to trigger a function of the module assembly, such as opening the hood element, in response to any hand movement of the user, in particular an upward movement or a swipe.

[0089] Figure 3 shows a view of a module assembly for arrangement on a motor vehicle. The module assembly has a base body 2, which is designed to provide a plurality of storage spaces 11, 11a, 11b (e.g., for accommodating objects such as luggage). For this purpose, the base body 2 is trough-shaped. Specifically, the base body 2 has a base element 20, from which an enclosing element 22 protrudes, by means of which the storage spaces 11, 11a, 11b are enclosed. A circumferential edge element 23 is provided on an upper edge of the enclosing element 22. The edge element 23 extends in a ring-shaped manner on the enclosing element 22. The edge element 23 can have a seal in order to seal the storage spaces 11, 11a, 11b (together with the hood element 12) against moisture penetrating from the outside. In addition, a collar 8 can be arranged on the edge element 23.

[0090] The edge element 23 has holes 231, via which the module assembly can be attached to a motor vehicle (e.g., to a ring-shaped support structure provided in the cargo area, which is fixed to the body). In principle, the module assembly can be secured to the motor vehicle in any desired manner. With mounting points such as holes 231 on the edge element 23, attachment is possible in a simple manner because the edge element 23 is easily accessible even after the module assembly has been inserted into the motor vehicle, so that installation can be carried out quickly and easily. Any number of holes 231 can be provided on the edge element 23.

[0091] The storage spaces 11, 11a, 11b are separated from one another by three wall elements 24. It is conceivable and possible to provide a large storage space by removing the wall elements 24. The four storage spaces differ in their size, particularly in their depth. A first and a second storage space 11, 11a have the same depth; two further storage spaces 11b are shallower. The arrangement and number of wall elements 24 is fundamentally arbitrary. For one of the wall elements 24 (the middle wall element 24), two guide elements 221 are provided on a border element 22, by which the storage space is bordered (these can, for example, be injection-molded onto the border element 22), each forming a guide track on a storage space-side side of the border element 22.The guide elements 221 are arranged on opposite sides of the enclosure element 22, so that the wall element 24 can be supported thereon (for example, by inserting it into the guide tracks). In principle, alternative designs of the guide elements 221 are also conceivable and possible.

[0092] The base body 2 has a plurality of mounting sections 25, to each of which a functional assembly is mounted. A first functional assembly has a control device 3. This is arranged on an outer side of the enclosure element 22, which faces away from the storage spaces 11, 11a, 11b. Two second functional assemblies each have a liquid container device 4. The liquid container devices 4 penetrate the enclosure element 22 from the exterior space into the storage space. They are designed such that they completely close an opening provided in the enclosure element 22 for the penetration. Two third functional assemblies each have an adjustment assembly 5, on which the hood element 12 can be arranged.

[0093] The control device 3 is coupled to the remaining functional assemblies 4, 5 via flexible transmission means 6. The flexible transmission means 6 are guided on holding elements 26 arranged on the base body 2. This allows a function of the module assembly, such as an adjustment of the adjustment assembly 5, to be tested in a pre-assembled state before the module assembly is arranged on the motor vehicle 1 (for example, without the hood element 12 being arranged on the adjustment assembly 5). In principle, the flexible transmission means 6 can be arranged on the base body 6 in any desired manner. A section of the flexible transmission means 6 is guided on the edge element 23 (at an angle of less than 180°, in particular less than 120°, which the enclosure element 22 and the edge element 23 form to one another).

[0094] Figure 4A shows at least one functional assembly in the form of a control device 3. This is contacted, for example, via a transmission medium 6 for transmitting power and / or data. The control device 3 has a mounting base 31, via which the control device 3 can be attached to a mounting section 25. Three coupling elements 311 are provided for attaching the control device 3. In principle, any number of coupling elements 311 is possible. However, a number of three coupling elements 311 can enable stable attachment with as few components as possible.

[0095] Counter elements 2511 in the form of (injected) undercuts are provided on the mounting section 25, with which the coupling elements 311 can be locked, as shown in Figure 4B. For this purpose, the coupling elements 311 are each inserted into the counter elements 2511 along an insertion direction E. The insertion takes place along a plane of the mounting section 25. In addition, the mounting section 25 forms a recess 28 on the base body 2, so that the control device 3 can be securely received on the base body 2.

[0096] The coupling elements 311 have a first coupling section, via which they can be coupled to a fastening receptacle 312 on the mounting base 31. Furthermore, the coupling elements 311 have a second coupling section, via which they can be coupled to the counter-elements 2511. The first coupling section has a smaller diameter than the second coupling section, so that the coupling elements 311 are conical. The first and second coupling sections are provided on the coupling elements 311 along a coupling axis, along which the coupling elements 311 couple the control device 3 to the base body 2.

[0097] The counter elements 2511 each have a release opening 2512, via which the coupling elements 311 can be disengaged from the counter elements 2511. Disengagement can be achieved, for example, by inserting a tool into the release opening 2512. The tool can be pressed against the coupling element 311 through the release opening 2512, so that the respective coupling element 311 moves out of the undercut of the respective counter element 2511, counter to the insertion direction E.

[0098] Figure 5 shows an alternative control device 3 as a further example of a functional assembly. The control device 3 has a mounting base 31, via which the control device 3 is mounted on four counter-elements 2511 of a mounting section of the base body 2. An electronic control unit 32 is arranged on the mounting base 31, which provides functions such as the control of other functional assemblies 4, 5 (for example, adjusting the adjustment assembly 5). For coupling to a further device (e.g., for data transmission or for supplying electrical power), the electronic control unit 32 has two connector receptacles 321.

[0099] The mounting base 31 has four coupling elements 311 in the form of elastic locking rings and four fastening receptacles 312. In the pre-assembled state, the coupling elements 311 are each fastened to the respective counter-element 2511 (exemplarily designed as a screw dome) via a first fastening section (not shown). Specifically, the first fastening section (e.g. in the form of an undercut) is arranged in the non-visible interior of the counter-elements 2511. The mounting base 31 can be screwed to the counter-elements 2511 via the four fastening receptacles 312 using fastening means 253 in the form of screws. This occurs during final assembly. The shown state of the control device 3 is a pre-assembly state in which the control device 3 is not fixed to the mounting section 25 with the final fastening force. The number of counter-elements 2511, coupling elements 311 and fastening receptacles 312 is shown here as an example.In principle, this number can be any desired. In principle, the coupling elements 311 can be designed such that the fastening force in the pre-assembled state is sufficient, so that no further step is necessary for final assembly. The following options are conceivable and possible in this case. The control device 3 can be locked to the mounting section 25 via plug-in areas provided on the mounting section 25 (such as the undercuts described above in Figs. 4A and 4B) and coupling elements 311 made of rubber. Screwing is not absolutely necessary in this case. Coupling elements 311 made of rubber can generally have the advantage that vibrations arising during operation of the functional assembly, in particular of the control device 3, are dampened (coupling element 311 as an absorber).In one variant (partial screw connection), at least one counter element 2511 can be provided on the mounting section 25, which is screwed to the mounting section 25. The counter element 2511 can be designed as a screw dome (as shown in Fig. 5). In a further variant (fully screwed connection), the at least one counter element 2511 can be screwed to the mounting section 25, as just described, and the coupling element 311 can additionally be screwed to the mounting section 31.

[0100] Figures 6A and 6B show views of two different embodiments of a liquid container device 4. The liquid container devices 4 each have a liquid container 42, which in turn has a base container 421 and a container extension 422 connected to the base container 421 to form a receiving space for the liquid. A filling opening 40 is provided on the container extension 422, through which liquid can be filled into the receiving space.

[0101] When properly arranged on the base body 2, as shown in Figure 2, the container extension 422 penetrates the enclosure element 22, so that the container extension 422 is arranged inside the storage space and the base container 421 is arranged outside the storage space. The base container 421, with one side on which the container extension 422 is arranged, closes the opening in the storage space at which the respective liquid container device 4 penetrates the enclosure element 22.

[0102] The filling opening 40 is separated from the storage space by a container rim 423 that protrudes above the filling opening 40. This prevents liquid from accidentally splashing into the storage space when filling. In this respect, the container rim 423 can form a seal between the filling opening 40 and the storage space.

[0103] The liquid container devices 4 each have a pair of mounting bases 41, via which the liquid container devices 4 can be arranged on the base body 2. The mounting bases 41 are each arranged on a recess 424 on the base container 421, which recess protrudes into the receiving space for the liquid. The recesses 424 are designed such that a mounting direction along which the liquid container devices 4 can be mounted on the base body 2 is parallel to the side of the base container 421 with which the base container closes the opening in the storage space, at which the liquid container devices 4 each penetrate the enclosure element 22. As a result, the recess 424 remains hidden from the storage space 11b, and the visual appearance of the liquid container device 4 can be improved. In principle, the arrangement and number of mounting bases 41 on the liquid container devices 4 is arbitrary.

[0104] The mounting bases 41 of the liquid container device 4 each have two locking receptacles 411 and two fastening receptacles 412. The liquid container devices 4 can be fastened to the base body 2 in a pre-assembled state via the locking receptacles 411. Specifically, the liquid container devices 4 can be locked to the base body 2 via the locking receptacles 411. For this purpose, the first fastening section 251 can have counter elements 2511 (not shown) that are designed to be positively connected to the locking receptacles 411. The liquid container devices 4 can be fastened to the base body 2 in the final assembly state via the fastening receptacles 412. This can be done, for example, by screwing the fastening receptacles 412 to the second fastening section 252 of the respectively assigned mounting section 25.The number of locking receptacles 411 and fastening receptacles 312 is given here as two as an example, but in principle the number is arbitrary.

[0105] Figure 7 shows a view of an adjustment assembly 5. The adjustment assembly 5 has a hood holder 52, which is pivotably mounted relative to a mounting base 51 of the adjustment assembly. The mounting base 51 is fastened to the base body 2. When properly mounted on a motor vehicle 1, a hood element 12 can be arranged on the hood holder 52, so that pivoting the hood element 12 relative to the base body 2 allows the hood holder 52 to pivot.

[0106] The mounting base 51 can, for example, have a drive device for driving a pivoting movement of the hood holder 52 and / or a locking element for locking the hood holder 52. The hood holder 52 cannot be pivoted in the locked state; pivoting is possible in the unlocked state. The mounting base 51 is fastened to a mounting section 25 of the base body 2, which comprises a first and a second fastening section 251, 252. The first fastening section 251 has two counter elements 2511 in the form of locking clamps, which are positively mounted in locking receptacles 511 on the mounting base 51 of the adjustment assembly 5. The adjustment assembly 5 is thereby fixed to the mounting section 25.

[0107] Under certain circumstances, however, the fastening force may not be sufficient to hold the hood element 12 on the hood holder 52 relative to the base body 2. For example, the two counter-elements 2511 may be torn off from the base body 2 under the weight of the hood element 12 due to a tearing force that exceeds a fastening force imparted by the counter-elements 2511. This means that the adjustment assembly 5, in the pre-assembled state, is not arranged on the base body 2 with a final fastening force. The second fastening section 252 cooperates for this purpose with two fastening receptacles 512 on the mounting base 51 in order to fasten the adjustment assembly 5 to the base body 2 with a final fastening force. This can be done, for example, using a fastening means such as a screw, via which the fastening receptacles 512 are screwed to the base body 2.The number of fastening receptacles 512 and counter elements 2511 can be any.

[0108] Figure 8 shows views of several base bodies 2 of identical construction. The base bodies 2 are inserted into one another and at least partially recessed into one another, allowing them to be stacked to save space. The trough-shaped design of the base bodies 2 is advantageous because it can accommodate the base body 2 above it. The three base bodies 2 can have a base area of ​​1400 x 850 mm. 2 and a volume of 1400 x 850 x 1000 mm 3take up space. The length of a single module assembly is thus greater than the height of two or more (here: three) module assemblies stacked on top of one another. Figure 9 shows a view of a module assembly with functional assemblies 7 in the form of locking assemblies 7. The locking assemblies 7 are arranged on a base element 20 of a base body 2 of the module assembly (via mounting sections 25 not shown). Between the locking assemblies 7, a plurality of support elements 27 are arranged, which are provided for supporting a cover element. The support elements 27 are hexagonal in cross-section parallel to the base element 20, although other designs of the support elements 27 are also conceivable and possible. The cover element 21 can be locked to the base element 20 for final assembly using the locking assemblies 7. For this purpose, the locking assemblies 7 engage in latching receptacles 212 on the cover element, as shown in Figure 10.In addition, the locking assemblies 7 each provide an interface for power transmission (e.g. for charging an eScooter).

[0109] Two guide elements 221 for a wall element 24 are provided on the edging element 22 of the base body 2. The guide elements 221 are provided on opposite sections of the edging element 22. They are groove-shaped. The cover element 21 can be fixed relative to the base element 20 with the wall element 24 in a pre-assembled state. Furthermore, the cover element 21 has two engagement elements 211, with which the cover element 21 engages in the guide elements 221 and via which it is positively mounted on the guide elements 221. In this respect, the guide elements 221 form a first fastening section 251 for the cover element 21. The locking assemblies 7 form a second fastening section 252 for the cover element 21.

[0110] Figure 11 shows a locking assembly 7, which has a locking element 71 adjustable via a drive motor 72, which is designed to engage the locking receptacles 212 on the cover element 21 in order to secure it relative to the base element 20. Furthermore, the locking element 71 provides the interface for power transmission.

[0111] Figure 12 shows a base body 2 with a base element 20, from which a border element 22 protrudes. A cover element 21 is arranged on the base element 20, forming a gap with the base element 20. A locking assembly 7 is arranged in the gap. Further functional assemblies arranged on the base body 2 by way of example are a control device 3, a liquid container device 4, an adjustment assembly 5, a locking assembly 7, a closing aid 91, a contact plug 92, a drain screw 93, a membrane 94, a seal 95, a component of an air conditioning device such as an air guide element 96, an electronic access module 97, with which the access to the storage space 11 can be controlled (e.g. by controlling an adjustment of a hood element 12 or a closure element 13), an HMI system 98, with which e.g.a status of the motor vehicle 1 can be checked, an emergency release lever 991, an emergency call device 992, and a loudspeaker 993. The HMI system is arranged, for example, in a recess 28 of the base body 2, wherein one or more functional modules can be arranged in the recess. The recess 28 has the shape of a drawer. The HMI system 98 can be accommodated therein in a watertight manner so that liquids from the storage space 11 cannot damage the HMI system.

[0112] Figure 13 shows a perspective view of a module assembly. The module assembly has a main opening for storing objects in the storage space 11 provided by the base body 2. A plane through the main opening is parallel to a floor on which the objects in the storage space 11 can be stored. In this case, the floor is formed by a floor element 20. In principle, the objects can alternatively be stored on a cover element 21 that covers the floor element 20. The main opening can be closed by a hood element 12. The hood element 12 is pivotally mounted on two adjustment assemblies 5 on the base body 2. The base body 2 thus forms an assembly unit with the hood element 12, which can facilitate the installation of the module assembly on a motor vehicle 1.

[0113] The modular assembly also has a secondary opening for storing items in the storage space 11. The secondary opening can be closed by an adjusting element 14. One plane of the secondary opening is arranged at an angle to the plane of the main opening. In principle, the modular assembly can only have one of the main opening and the secondary opening. Providing both openings allows users to access the storage space 11 more conveniently from different directions.

[0114] The adjustment element 14 is connected to the base body 2 via two adjustment assemblies 5. One of the adjustment assemblies 5 has an adjustment drive 53. This allows the adjustment of the adjustment element 14 to be performed. For example, a user of the module assembly can actuate the adjustment drive 53 to release the secondary opening. The adjustment drive 53 has a spindle drive and a spindle element that engages the adjustment element 14. Specifically, the adjustment of the adjustment element 14 is performed via an adjustment arm 141 of the adjustment element 14, to which the spindle element engages.

[0115] A further adjustment assembly 5, via which the adjustment element 14 is connected to the base body 2, has a tension element 54. The tension element 54 can, for example, comprise a wire or a cable. The tension element 54 is fixed at one end to the base body 2. The other end of the tension element 54 is fixed to the adjustment element 14 (alternatively, the other end can be fixed to one of the adjustment arms 141). In the open position of the adjustment element 14, in which it releases the secondary opening, the tension element 54 is tensioned so that it limits an adjustment path of the adjustment element 14 from a closed position, in which the adjustment element 14 closes the secondary opening, to the open position. For example, the adjustment element 14 can thus be subjected to a load in the open position, wherein the load is absorbed by the tension element 54.

[0116] The adjustment assemblies 5 are each secured to the base body 2 in an area having support elements 27 in the form of three ribs. The number and shape of the ribs are shown here merely as examples. In principle, any number and shape of ribs can be provided. The support elements 27 reinforce the respective section to which the adjustment assemblies 5 are secured. Furthermore, the area is arranged near an edge element 23 of the base body 2, which protrudes outward from the enclosure element 22 (away from the storage space 11). The module assembly is connected to the motor vehicle 1 via the enclosure element 22 (via bores 231). The proximity of the arrangement of the adjustment assemblies 5 for the adjustment element 14 to the edge element 23 can improve the stability of the securing.For example, a fixing point of the respective adjustment assembly 5 on the base body 2 can correspond to a distance of less than 20% of a height of the edging element 22 above the floor element 20. For example, the fixing point can thus be at a height of more than 80% of a height of the edging element 22 above the floor element 20.

[0117] The two illustrated adjustment assemblies 5 are provided merely as examples. The adjustment element 14 can generally be manually adjustable and / or only one of the two illustrated adjustment assemblies 5 can be provided. Alternatively, one of the illustrated adjustment assemblies 5 can be provided on both sides. By way of example, the adjustment element 14 is mounted relative to the base body 2 so as to be pivotable about a pivot axis (e.g., via the hinges shown). This mounting can be provided alternatively or in addition to the mounting on at least one adjustment assembly 5 (e.g., on the two illustrated adjustment assemblies 5).

[0118] The module assembly further comprises two loudspeakers 993, which are shown as examples for any number of one or more loudspeakers. A first loudspeaker 993 is provided in a recess 28 on the surround element 22. The recess 28 is provided on a step of the surround element 22, which forms a section that is parallel to the base element 20. The recess

[0119] 28 can be covered by a cover element. A second loudspeaker 993 is provided on a flat section of the surround element 22. The second loudspeaker 993 comprises a piezo actuator with which the flat section can be excited to generate sound. The loudspeakers 993 can be used, for example, to generate vehicle sounds. This can be used to alert pedestrians to the presence of the motor vehicle 1 when it is moving slowly (e.g., below 30 km / h).

[0120] A flexible transmission means 6 is arranged on the edging element 22, via which, for example, the adjustment drive 53 and one of the loudspeakers 993 are coupled to each other. The flexible transmission means 6 is guided on a side of the edge element 23 facing away from the main opening, so that it is not visible from the outside when the module assembly is properly assembled. A first flexible transmission means 6 extends to each of the adjustment drive 53 and the loudspeaker 993.

[0121] The module assembly further comprises a connecting section 29, which extends on a side of the floor element 20 facing away from the edging element 22. The edging element 22 and the connecting section 29 are integrally connected to one another. The connecting section 29 has a wedge-shaped structure in cross-section transverse to the floor element 20, the tip of which is arranged on a rear side of the module assembly in the direction of travel. A component of an air conditioning device in the form of a fan 96a is arranged on the connecting section 29.

[0122] Figure 14 shows a side view of the connecting section 29. The connecting section

[0123] 29 provides an air duct extending along the direction of travel. A fan-side end of the connecting portion 29 is formed obliquely to a cooler-side end of the connecting portion 29, which is opposite the other end along the direction of travel. A fan 96a is provided at the fan-side end of the connecting portion 29. The fan 96a is connected to the connecting portion 29 via a funnel. A cooling component 96b is provided at the cooler-side end of the connecting portion 29. For example, air from outside the motor vehicle 1 can be cooled with the cooling component 96b and supplied to an interior of the motor vehicle 1 via the fan 96a.
