Description

TECHNICAL FIELD

[0001] The present application relates to a housing device for a motor vehicle for accommodating at least one rechargeable storage module for electrical energy. The present application furthermore relates to a storage module for accommodation in a housing device according to the present application, a housing system comprising a housing device and at least one storage module. The present application also relates to a motor vehicle having a housing device or having a housing system and to a method for accommodating a storage module in a housing device and / or for removing a storage module from a housing device. BACKGROUND

[0002] The aim of current HV battery pack housing developments is to construct the volume for the battery cells as large as possible and the housing as small as possible, wherein all mechanical load situations must be withstood without fire and without short circuit. In order to achieve the maximum power and energy density, the structural components must be designed in a space-saving and as non-redundant as possible manner. At the same time it is advantageous to provide sufficient structural space for electrical lines and control devices in the housing in addition to the structural space for the batteries. HV battery pack systems have been shown up to now essentially in a manner focusing on the safety integration of different battery pack capacities. Although replacement storage modules are known as a possibility, the replacement storage modules are always replaced with increased outlay, for example with the use of trained professionals, i.e. not automatically. In future mobility concepts, the quick, automatic replacement of battery pack modules and / or battery pack cells becomes increasingly important. Here, the limits of the existing possibilities, which are mostly manual, are reached or exceeded.

[0003] Replacement of these battery pack systems and / or parts thereof is generally not provided or only carried out at the time of repair. Battery pack modules which carry a load provide the possibility of scheduled replacement, for example for effective range adaptation. However, common to all systems is that the replacement is carried out at least partially manually and with high time outlay due to the construction design of the battery pack modules and / or the housing device or their coupling. Replacement devices are known, but the replacement or connection is generally carried out with screws.

[0004] Large battery pack housings are in particular heavy and not light. It is therefore not possible to remove a battery pack module, for example for the purpose of customer service or for customer-side effective range adaptation; the entire battery pack housing is always disassembled and reassembled with high outlay. At the same time, more outlay and therefore more expensive logistics and production are required.

[0005] The replacement in the current system situation can only be realized with additional personnel effort, i.e. with a significantly high cost, and / or the required hardware components are complex and space-intensive, since they are not designed with a uniform functional integration and / or for very large ungrouped battery pack systems. Thereby, additionally, high operating and maintenance costs and a prolonged replacement duration arise, which is not suitable for use in modern traffic and vehicle concepts.

[0006] The currently known automatic replacement systems mostly use screws for connecting the HV battery pack to the vehicle. This prolongs the replacement in time and requires a replacement station with a high effort of screws. Furthermore, the screws are susceptible to wear - especially when the screw hole is not hit precisely and accurately parallel, which is often to be expected (e.g. due to tolerances). For example, a battery pack replacement device is known from WO 2012 / 116916 A2, which requires a special additional frame, which establishes the connection of the battery pack system to the vehicle or contains / accommodates the connection elements. SUMMARY

[0007] It is therefore the task of the present invention to at least partially eliminate the above-mentioned disadvantages of the prior art. In particular, it is the task of the present invention to provide a housing device for a motor vehicle for accommodating at least one rechargeable storage module for electrical energy, with which it is possible to particularly easily, in particular automatically or semi-automatically, remove at least one storage module from at least one accommodation compartment of the housing device and / or to accommodate at least one storage module into at least one accommodation compartment of the housing device. Furthermore, it is the task of the present invention, in particular, to provide a storage module for accommodation in a housing device according to the invention, a housing system comprising a housing device and at least one storage module, a motor vehicle having a housing device or having a housing system and a method for removing a storage module from a housing device and / or for accommodating a storage module in a housing device.

[0008] The above task is solved by the present application. In particular, the task is solved by a housing device for a motor vehicle for accommodating at least one rechargeable storage module for electrical energy having the features according to the present application. Furthermore, the task is solved by a storage module having the features according to the present application, by a housing system having the features according to the present application, by a motor vehicle having the features according to the present application and by a method having the features according to the present application. Further advantages and details of the present application result from the dependent claims, the description and the drawings. Here, the features described in connection with the housing device according to the present application apply of course also in connection with the storage module according to the present application, the housing system according to the present application, the motor vehicle according to the present application, the method according to the present application, and vice versa, respectively, so that the disclosure with respect to the individual inventive aspects is or can be mutually referred to.

[0009] According to a first aspect of the present application, the task is solved by a housing device for a motor vehicle for accommodating at least one rechargeable storage module for electrical energy. The housing device comprises at least one accommodation compartment, wherein each accommodation compartment is configured for accommodating at least one storage module, wherein the housing device has at least one mechanical interface for form-fitting locking of at least one corresponding interface of the storage module in a releasable manner, wherein the housing device has at least one electrical connection for electrically contacting at least one corresponding electrical connection of the storage module. Furthermore, the mechanical interface comprises at least one guide device and at least one locking element, wherein the at least one guide device is designed for guiding at least one corresponding guide device of the storage module and is arranged in a non-movable manner with respect to the accommodation compartment, wherein the at least one guide device is designed to block movement of the at least one corresponding guide device along at least one spatial axis in an installed position of the storage module in the accommodation compartment, respectively, wherein the at least one locking element is laged in a movable manner between an unlocked position and a locked position, wherein the at least one locking element enables the removal of the at least one storage module from the at least one accommodation compartment or the accommodation of the at least one storage module into the at least one accommodation compartment in the unlocked position, and wherein the storage module can be form-fittingly locked in the locked position by the locking element in the installed position of the storage module in a releasable manner.

[0010] The accommodation compartment can be designed, in particular, by the motor vehicle, at least on one side. The accommodation device and the accommodation compartment are preferably arranged in a bottom section of the motor vehicle. The application is described exemplarily by means of a design of the accommodation device in which the storage module is inserted from below into an installation position of the storage module in the accommodation compartment of the accommodation device. The installation position is to be understood as the position of the storage module in the accommodation device in which the storage module is positively locked, i.e. fixed in its position, and in which the electrical connection terminals of the storage module are electrically connected, i.e. the energy supply function of the storage module can be implemented, with the accommodation device. The storage module is mechanically locked at the accommodation device by means of a mechanical interface of the accommodation device. For this purpose, the mechanical interface has at least one guide device and at least one locking element. In the exemplary design by means of which the application is described, the at least one guide device is screwed and / or welded and / or otherwise structurally configured at the vehicle body of the motor vehicle. The at least one guide device is described exemplarily as a guide slot and / or a slide groove guide. At least one corresponding guide device of the storage module is described exemplarily as a bolt and / or other structural element which protrudes from the storage module for guidance in the at least one guide device. Of course, the design of the guide device and the corresponding guide device can also be designed in reverse, so that the storage module comprises at least one guide slot and the accommodation device comprises at least one guide element, such as a bolt, for guidance in the guide slot. As shown in detail in the following paragraphs, the accommodation device advantageously has at least one guide device, in particular a plurality of guide devices, at one side of the accommodation compartment, in particular at a plurality of sides of the accommodation compartment. The guide device according to the application is particularly advantageous because the at least one guide device is designed to block the movement of the at least one corresponding guide device along at least one spatial axis in the installation position of the storage module in the accommodation compartment, respectively. The guide device of the accommodation device is thus designed to limit the movement of the storage module in at least two degrees of freedom, respectively.

[0011] Within the scope of the application, the spatial axes are to be defined by way of example with a motor vehicle according to the application, wherein the accommodation system and the at least one storage module are arranged along a bottom region of the motor vehicle. The X-axis corresponds to the driving direction of the motor vehicle, the Y-axis corresponds to the lateral direction of the motor vehicle and the Z-axis corresponds to the upward and downward direction with respect to the exemplary design of the motor vehicle.

[0012] The mechanical interface furthermore comprises at least one locking element which is arranged in a movable manner between an unlocked position and a locked position. The device according to the application preferably provides means for form-fittingly locking the storage module in a releasable manner on the basis of the interaction of the elements of the mechanical interface, the at least one guiding device and the at least one locking element. The locking element is preferably designed to prevent movement of the storage module in the accommodation compartment, in particular in the installed position of the storage module, along the X spatial axis. The locking element can be loaded by means of a tension force, in particular in the direction of the locked position. This tension force can be achieved by means of spring devices, pneumatic devices, hydraulic devices and / or the accommodation device and / or other tension devices of the motor vehicle. Preferably, the storage module according to the application is guided into the accommodation device by means of the at least one guiding device for guiding the at least one corresponding guiding device of the storage module. The storage module is then form-fittingly locked in a releasable manner by moving the locking element between the unlocked position and the locked position. The fixing element thus enables a second form-fitting coupling with the storage module, in particular with the outer geometry of the storage module, and thus, in combination with the guiding device, enables a form-fitting and releasable locking of the storage module with the accommodation device. As described in more detail later for the method according to the application, it can be advantageous to determine the sequence of these form-fitting couplings. Thus, for example, it is advantageous to first initiate the coupling of the storage module with the guiding device and then, or at least in sections, to produce the coupling with the locking element in time parallel. In order to remove the storage module from the locking compartment, it is advantageous to first release the coupling of the locking element in the reverse sequence and then, or at least in sections, to release the coupling of the locking pin with the storage module in time parallel. Thus, the storage module for electrical energy, which is described in more detail later, is held in the installed position of the storage module after being accommodated in the accommodation device by means of the position- fixed guiding device and the movable locking element. The accommodation device according to the application can preferably comprise at least two or multiple guiding devices in order to be able to achieve a reliable, form-fitting and releasable locking of the storage module with the accommodation device, for example over a larger area and / or via multiple force introduction points. Thus, the accommodation device according to the application advantageously enables, by means of the combination of the at least one guiding device and the at least one locking element, simple, fast and in particular tool-free accommodation or removal of the storage module for electrical energy in the accommodation device. Thus, by means of the accommodation device according to the application, it is advantageously possible to remove and / or accommodate at least one storage module from / to at least one accommodation compartment of the accommodation device by means of a change device with a change platform, in particular automatically or semi-automatically.

[0013] According to a preferred development of the application, in the case of a receiving device it can be provided that the at least one first guide device of the mechanical interface is arranged at a first longitudinal side of the receiving compartment and the at least one second guide device is arranged at a second longitudinal side of the receiving compartment, in particular wherein the first longitudinal side and the second longitudinal side are arranged parallel or substantially parallel to one another. In the context of the present application, the expression "X or substantially X" is to be understood as a possible small deviation, for example due to manufacturing tolerances and / or material properties, without changing the intended function of the underlying feature. In order to advantageously make optimum use of the installation space, the receiving compartment is preferably dimensioned or substantially dimensioned to the at least one storage module. The storage module and the receiving compartment are generally designed as rectangular cuboids. Additionally or alternatively, the first guide device and the second guide device are arranged in one plane or in a plurality of parallel planes, in particular along the X-axis and / or parallel to the Y-axis. Instead of an extension of the guide devices from the longitudinal sides of the receiving compartment and / or the exemplary arrangement, the guide devices likewise exemplarily can additionally or alternatively have an extension in the Z-axis with respect to the motor vehicle, so that the guide devices in the respective storage module engage from above into the corresponding interface and / or the corresponding guide device arranged at the storage module in order to enable the form-fit coupling according to the application. A receiving device thus designed advantageously enables guiding of the corresponding guide device of the storage module by the guide devices of the receiving device. The guide devices are preferably designed such that the guide devices are undercut at least in sections by the corresponding guide device. A receiving device thus designed enables, for example by the first guide device and by the second guide device, the prevention of a movement of the at least one corresponding guide device, in particular in the installed position of the storage module in the receiving compartment, along the Z spatial axis. Additionally, a receiving device thus designed can enable, for example by laterally limiting the first guide device and the second guide device, the prevention of a movement of the at least one corresponding guide device, in particular in the installed position of the storage module in the receiving compartment, along the Y spatial axis.

[0014] According to a preferred development of the application, in the case of the accommodation device it can be provided that at least one third guide device of the mechanical interface is arranged at an end face of the accommodation compartment, wherein the end face is oriented in particular orthogonally or substantially orthogonally to the first longitudinal side and the second longitudinal side. Additionally or alternatively, the third guide device is arranged in a common plane or in parallel planes with respect to the first guide device and / or the second first guide device, in particular along the X axis and / or parallel to the Y axis. In particular in combination with the first guide device and the second guide device which preferably enable undercutting with the corresponding guide device of the at least one storage module, the third guide device according to the application supplements: for example, in particular an eindringen of the respective corresponding guide device along the X axis. An accommodation device of this design enables, for example, the prevention of a movement of the at least one corresponding guide device along the Y axis and / or the Z axis, in particular in the installed position of the storage module in the accommodation compartment, by means of the third guide device.

[0015] According to a preferred development of the application, in the case of the accommodation device it can be provided that at least one locking element is designed in such a way that the storage module, in the installed position of the storage module, can be locked by the locking element in the locked position along at least one spatial axis, in particular along two spatial axes, by the at least one locking element in a form-fitting and releasable manner. The device according to the application preferably provides, on the basis of the interaction of the elements of the mechanical interface, of the at least one guide device and of the at least one locking element, a device for form-fitting and releasable locking of the storage module. The locking element is preferably designed for preventing a movement of the storage module in the accommodation compartment, in particular in the installed position of the storage module, along the X spatial axis. However, the locking element can additionally or alternatively enable, for example, a prevention of a movement of the storage module in the accommodation compartment, in particular in the installed position of the storage module, along the Y spatial axis, for example by engaging a protrusion, a pin and / or other structural components into the storage module, in particular in the installed position of the storage module. Exemplarily, the storage module according to the application is guided into the accommodation device via the at least one guide device for guiding the at least one corresponding guide device of the storage module. Also exemplarily, subsequently, simultaneously or at least sectionally simultaneously, the storage module is form-fittingly and releasably locked by moving the locking element between the unlocked position and the locked position. An accommodation device of this design is particularly advantageous because it is particularly simple to implement: in particular automated or semi-automated accommodation of at least one storage module into at least one accommodation compartment of the accommodation device and form-fitting and releasable locking by means of a changing device with a changing platform.

[0016] According to a preferred development of the application, in the case of a receiving device it can be provided that the at least one guide device has a first guide section and a second guide section, wherein the first guide section enables the introduction of the at least one corresponding guide device into the guide device and the second guide section enables the undercutting of the guide device by the at least one corresponding guide device. The introduction of the corresponding guide device into the guide device is advantageously enabled by the first guide section. For example, the corresponding guide device of a storage module is introduced from below into the at least one guide device of the receiving device, in particular in the direction of the Z axis. By moving the corresponding guide device along the second guide section, in particular in the direction of the X axis, the undercutting of the guide device by the at least one corresponding guide device is enabled. The first guide section and the second guide section are designed together and / or transition into one another. These guide sections are preferably arranged at an angle to one another, in particular 90° or substantially 90°. The first guide section preferably has a conical design at least in sections, so that the introduction of the corresponding guide device into the at least one guide device is facilitated. The second guide section preferably has a closed end in order to limit and / or define the installation position of the corresponding guide device of a storage module. Preferably, the first guide section and the second guide section represent sections of a single guide slot and / or guide slide. A receiving device of this design enables, for example, the automated or semi-automated insertion of storage modules by means of a replacement device having a replacement platform, and thus in particular advantageously fulfils the task according to the application.

[0017] According to a preferred development of the application, in the case of a receiving device it can be provided that the at least one guide device has a first guide section and a second guide section, wherein the first guide section enables the introduction of the at least one corresponding guide device into the guide device and the second guide section enables the undercutting of the guide device by the at least one corresponding guide device. The introduction of the corresponding guide device into the guide device is advantageously enabled by the first guide section. For example, the corresponding guide device of a storage module is introduced from below into the at least one guide device of the receiving device, in particular in the direction of the Z axis. By moving the corresponding guide device along the second guide section, in particular in the direction of the X axis, the undercutting of the guide device by the at least one corresponding guide device is enabled. The first guide section and the second guide section are designed together and / or transition into one another. These guide sections are preferably arranged at an angle to one another, in particular 90° or substantially 90°.

A receiving device of this design enables, for example, the automated or semi-automated insertion of storage modules by means of a replacement device having a replacement platform, and thus in particular advantageously fulfils the task according to the application.

[0018] According to a preferred development of the application, in the case of the housing device it can be provided that the housing device has a sensor device and a control device, wherein the sensor device is designed to detect the position of the storage module in the at least one housing compartment, wherein the control device is designed to control the movement of the locking element between the unlocked position and the locked position, in particular on the basis of the position of the storage module detected by the sensor device. Instead of or in addition to the tensioning device described above, the movement of the locking element can be controlled by the control device. Advantageously, the movement of the locking element is controlled by the control device on the basis of the position of the storage module detected by the sensor device, such that the locking element is moved into the locked position by the control device when it has been identified that the storage module is in the installation position of the storage module and thus enables a form-fitting locking of the storage module with the housing device, in particular automatically.

[0019] According to a second aspect of the application, the task is solved by a storage module for housing in a housing device according to the first aspect. The storage module has at least one corresponding interface for force-fittingly fixing the storage module in an installation position of the storage module in a housing compartment of the housing device and at least one electric corresponding connection end for electric contact with an electric connection end of the housing device, wherein the at least one corresponding interface has at least one corresponding guide device for guided contact with the at least one guide device of the housing device.

As described above, the locking element is preferably designed to prevent movement of the storage module in the housing compartment, in particular in the installation position of the storage module, along the X spatial axis. For the guidance, the locking element can be in locking contact with the corresponding locking element. Additionally or alternatively, movement of the storage module in the housing compartment, in particular in the installation position of the storage module, along the Z spatial axis can be prevented, for example by engaging a protrusion, a pin and / or other structural components of the locking element into the storage module, in particular into the corresponding locking element of the storage module. The corresponding locking element can preferably be designed conically in order to simplify the introduction of the locking element.

[0021] According to a preferred development of the application, in the case of a storage module it can be provided that at least one first corresponding guide device of the corresponding interface is arranged at a first longitudinal side of the storage module and at least one second corresponding guide device is arranged at a second longitudinal side of the storage module, wherein the first longitudinal side and the second longitudinal side are arranged parallel or substantially parallel to one another.

The housing device of the housing system is designed according to the first aspect of the application and the storage module of the housing system is designed according to the second aspect of the application. All advantages already described for the storage module according to the second aspect of the application and for the housing device according to the first aspect of the application apply in the case of the described housing system.

[0024] According to a fourth aspect of the application, the task is solved by a motor vehicle having a housing device or a housing system, wherein the housing device is designed according to the first aspect or the housing system is designed according to the third aspect of the application. All advantages already described for the housing system according to the third aspect of the application and for the housing device according to the first aspect of the application apply in the case of the described motor vehicle.

[0035] The at least one guiding device and / or the at least one locking element are advantageous design and embodiment solutions of the mechanical interface. The accommodation device thus designed enables, for example, by means of the first guiding device and by means of the second guiding device, the at least one corresponding guiding device to be blocked from moving along the Z spatial axis, in particular in the installed position of the storage module in the accommodation compartment. Additionally, the accommodation device thus designed can enable, for example, by laterally limiting the first guiding device and the second guiding device, the at least one corresponding guiding device to be blocked from moving along the Y spatial axis, in particular in the installed position of the storage module in the accommodation compartment. When the storage module is pushed into the installed position, the at least one locking element is moved into the locking position, for example, by means of spring devices and / or by means of gravity, and thus enables the storage module to be particularly advantageously positively locked in the accommodation device in a releasable manner.

[0043] In the drawings: Figures 1 to 6 Elements having the same function and mode of action are each provided with the same reference signs. DETAILED DESCRIPTION

[0044] In the drawings: Figure 1In Fig. 3, the mechanical interface 12 and the electrical connection 18 of the housing device 1 and the storage module 30 with the corresponding interface 32 and the electrical corresponding connection 36 are shown schematically in perspective view. The mechanical interface 12 is designed as two parallel guide devices 14 in the form of a parallel sliding groove guide with a first guide section 15 and a second guide section 16. The corresponding guide device 34 of the storage module is designed as a cylinder and penetrates into the guide devices 14 along a penetration axis EA. The first guide section 15 is designed conically in order to simplify the penetration. By moving the storage module 30 along an undercut axis HA, the guide devices 14 are undercut by the corresponding guide device 34 and the end face corresponding guide device 34 at the first end face 44 of the storage module penetrates into the end face guide devices 14 of the housing device 1. Here, the electrical connection 18 of the housing device 1 comes into contact with the electrical corresponding connection 38 and enables the provision of the stored electrical energy from the storage module 30 to the housing device 1 and / or to a superior system, for example a motor vehicle 60 (not shown). The guide devices 14 according to the application are particularly advantageous because the at least one guide device 14 is designed to prevent the movement of the at least one corresponding guide device 34 along at least one spatial axis X, Y, Z in the installed position EBP (not shown) of the storage module 30 in the housing compartment 10. Thus, each of the guide devices 14 of the housing device 1 is designed to limit the movement of the storage module 30 in at least two degrees of freedom, respectively, and the housing device 1 is designed by means of the mechanical interface 12 to house at least one storage module 30 and to lock the at least one storage module 30 form-fittingly and releasably.

[0045] In Figure 2In the middle, a housing system 50 with a housing device 1 and a storage module 30 is shown schematically in a side view. The storage module 30 is shown below the housing device 1. Furthermore, the storage module 30 in the installation position EBP within the housing compartment 10 of the housing device 1 is shown by a dotted line. For the accommodation of the storage module 30, the locking element 17 is linearly moved by the storage module 30 to be accommodated from the locking position VP to the unlocking position EP. Here, the mechanical counter-interface 32 of the storage module 30 penetrates along the penetration axis EA into the mechanical interface 12, in particular into the guide device 14. By linearly moving the storage module 30 along the undercut axis HA, on the one hand the counter-interface 32 of the storage module 30 is undercut by the mechanical interface 12, and on the other hand the locking element 17 is released and thus moved into the locking position VP. Thus, the storage module 30 is coupled and positionally fixedly arranged in a form-fit manner at least at two points. By linearly moving the storage module 30 along the undercut axis HA, a contact between the electrical connection end 18 of the housing device 1 and the electrical counter-connection end 38 is also exemplarily implemented, and thus the possibility of powering the motor vehicle 60 (not shown) by the storage module 30 is enabled. The housing device 1 additionally comprises an end-face guide device 14, into which an end face of the storage module 30 penetrates by moving the storage module 30 along the undercut axis HA. The housing device 1 furthermore has an optional sensor device 47 and an optional control device 48, which are in operative connection with the locking element 17. Instead of or in addition to the tensioning device, the movement of the locking element 17 can be controlled by the control device 48. Advantageously, the movement of the locking element 17 is controlled by the control device 48 on the basis of the position of the storage module 30 detected by the sensor device 47, such that the locking element 17 is moved into the locking position VP by the control device 48 when the storage module 30 is accommodated and when it has been identified that the storage module 30 is in the installation position EBP of the storage module 30, and thus the storage module 30 is locked in a form-fit manner, in particular automatically, with the housing device 1. Conversely, the control device 48 is preferably designed to move the locking element 17 into the unlocking position EP if necessary when the storage module 30 is removed.

[0046] In Figure 3The receiving device 1 with the third guide device 14 and the storage module 30 are shown in an end view. The third guide device 14 is arranged in a common plane or in parallel planes, in particular along the X axis and / or parallel to the Y axis, in addition to or instead of the first guide device 14 and / or the second first guide device 14. In particular in combination with the first guide device 14 and the second guide device 14, which preferably enable undercutting with a corresponding guide device 34 of the at least one storage module 30, the third guide device 14 according to the application, for example, supplements: the respective corresponding guide device 34 here penetrates into the drawing plane, in particular along the X axis. The receiving device 1 thus designed enables, for example, by means of the third guide device 14, to prevent a movement of the at least one corresponding guide device 34, in particular along the Y axis and / or the Z axis, in the installation position EBP (not shown) of the storage module 30 in the receiving compartment 10.

[0047] In Figure 4 The form-fitting active connection between the storage module 30 and the locking element 17 of the receiving device 1 is shown in a perspective view. The locking element 17 can be accommodated in a linearly movable manner and / or in a rotatable manner about a locking axis VA in order to enable a form-fitting releasable locking of the storage module 30 in the installation position EBP in the receiving device 1 (not shown). The locking element 17 can realize a locking at the outside of the storage module 30 or can engage at least section-wise into the storage module 30 and / or recesses, in particular corresponding locking elements 36, of the storage module 30, not only in the case of a linear movement but also in the case of an additional or alternative rotational movement. The locking element 17 thus designed is particularly advantageous, since it enables a secure form-fitting and releasable locking of the storage module 30 in the receiving device 1 with simple means.

[0048] In Figure 5In the perspective view, the locking element 17 of the accommodation device 1 and the storage module 30 are shown, which has two corresponding locking elements 36 at the second end face 46 of the storage module 30. In addition to at least one guide device 14 (not shown), the mechanical interface 12 comprises at least one locking element 17, which is arranged in a movable manner between an unlocked position EP and a locked position VP (not shown). The accommodation device 1 according to the application provides, preferably based on the interaction of the elements of the mechanical interface 12, at least one guide device 14 (not shown) and at least one locking element 17, an accommodation device 1 for positively locking the storage module 30 in the accommodation compartment 10 in a releasable manner. The locking element 17 is preferably designed to prevent movement of the storage module 30 in the accommodation compartment 10, in particular in the installed position EPB (not shown) of the storage module 30, along the X spatial axis. The locking element 17 can be loaded by means of a tension, in particular in the direction of the locked position VP (not shown). This tension can be achieved by means of spring devices, pneumatic devices, hydraulic devices and / or other tension devices of the accommodation device 1 and / or the motor vehicle 60 (not shown). In the design shown, the storage module has two corresponding locking elements 36, which are designed to come into locking contact with one locking element 17 in the locked position VP (not shown). By means of the engagement of the protrusions, pins and / or other structural designs of the locking element 17, it is possible to prevent additional movement of the storage module 30 in the accommodation compartment 10, in particular in the installed position EBP (not shown) of the storage module 30, along the Z spatial axis. The corresponding locking elements 36 can preferably be designed conically in order to simplify the introduction of the locking element 17.

[0049] In Figure 6 The motor vehicle 60 with the accommodation system 50 is shown schematically in a side view. This design of the motor vehicle 60 with the accommodation system 50 according to the application or the accommodation device 1 according to the application is particularly advantageous, since a reliable, cost-effective and simple coupling, in particular a positively locking coupling, between the storage module 30 and the accommodation device 1 can be achieved by undercutting the corresponding interface 32 at least regionally by the head 18 of the mechanical interface 12, in particular the locking pin 14. By means of the accommodation device 1 according to the application, it is advantageously possible to remove and / or accommodate the at least one storage module 30 from and / or in the at least one accommodation compartment 10 of the accommodation device 1 of the motor vehicle 60, in particular automatically or semi-automatically, by means of a change device with a change platform.
