Description

The present invention relates to a receiving device for a motor vehicle for receiving at least one rechargeable storage module for electrical energy. The invention also relates to a storage module for receiving in a receiving device according to the invention, a receiving system comprising a receiving device and at least one storage module. The invention also relates to a motor vehicle with a receiving device or with a receiving system and a method for receiving and / or removing a memory module in / from a receiving device.

The aim of the current HV battery housing development is to design the volume for the battery cells as large as possible and the housing as small as possible, whereby all mechanical load cases have to be endured without fire and without short circuit. In order to achieve the maximum power and energy density, structural components must be designed to save space and, if possible, without redundancies. At the same time, it is advantageous if, in addition to the installation space for the cells, sufficient installation space is kept within the housing for the electrical lines and control devices. Up to now, HV battery systems have essentially focused on the safe integration of different battery capacities. An exchange of memory modules is already known as a possibility, but always with increased effort, for example with the use of trained specialist personnel, that is, not automated. In the course of future mobility concepts, a quick, automated change of battery modules and / or battery units is becoming more and more important. Here the limits of the existing - mostly manual - possibilities are reached or exceeded.

The replacement of these battery systems and / or parts thereof is generally not intended or only takes place during repairs. Load-bearing battery modules offer the option of scheduled replacement - for example to adjust the range. What all systems have in common, however, is that the change takes place at least partially manually and with a high expenditure of time due to the structural design of the battery modules and / or the receiving devices or their coupling. Changing devices are known, but changing or connecting is generally done with screws.

Large battery cases, in particular, are heavy and unwieldy. A single removal of battery modules, e.g. B. for purposes of customer service or for customer-side range adjustments, is not possible; the entire battery housing is always dismantled and reassembled with great effort. At the same time, more complex and therefore more expensive logistics and production are required.

The change in the current systems is only possible with additional personnel, i. H. Significantly high costs, possible and / or the required hardware components are complex and space-intensive, since they do not pursue a consequent functional integration and / or are designed for very large, non-structured battery systems. This also results in high operating and maintenance costs as well as a longer replacement time, which is unsuitable for use in modern traffic and vehicle concepts.

The currently publicly known automatic changing systems mostly use screws to connect the HV battery to the vehicle. This lengthens the change in time and requires a complex changing station with a large number of screws. In addition, the screws are prone to wear - especially if the screw holes are not hit exactly and precisely in parallel, which is generally to be expected - for example due to tolerances. For example, a battery changing device is known from US Pat WO 2012/116916 A2 , which requires a special additional frame that establishes the connection of the battery system to the vehicle or contains / accommodates the connecting elements.

It is therefore the object of the present invention to at least partially remedy the above-described disadvantages in the prior art. In particular, the object of the invention is to provide a receiving device for a motor vehicle for receiving at least one rechargeable storage module for electrical energy, with which the at least one storage module can be removed from the at least one receiving compartment of the receiving device and / or the at least one storage module can be received in the at least one receiving compartment of the receiving device, in particular automated or partially automated, is made possible in a particularly simple manner. In particular, it is also the object of the invention to provide a storage module for receiving in a receiving device according to the invention, a receiving system comprising a receiving device and at least one storage module and a motor vehicle with a receiving device or with a receiving system and a method for receiving and / or removing a memory module in / from to provide a recording device.

In particular, the The object is achieved by a receiving device for a motor vehicle for receiving at least one rechargeable storage module for electrical energy with the features of independent claim 1. Furthermore, the object is achieved by a storage module with the features of independent claim 8, by a receiving system with the features of independent claim 12, by a motor vehicle having the features of independent claim 13 and by a method having the features of independent claim 14. Further advantages and details of the invention emerge from the subclaims, the description and the drawings. Features that are described in connection with the recording device according to the invention naturally also apply in connection with the memory module according to the invention, the recording system according to the invention, the motor vehicle according to the invention, the method according to the invention and vice versa, so that reference is always made to the individual aspects of the invention with respect to the disclosure will or can be.

According to a first aspect of the invention, the object is achieved by a receiving device for a motor vehicle for receiving at least one rechargeable storage module for electrical energy. The receiving device comprises at least one receiving compartment, each receiving compartment being designed to receive at least one memory module, the receiving device having at least one mechanical interface for positive, releasable locking with at least one counter-interface of the memory module, the receiving device having at least one electrical connection for electrically contacting at least one having electrical mating connection of the memory 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 to guide at least one counter-guide device of the storage module and is arranged immovably relative to the receiving compartment, the at least one guide device in each case for blocking a movement of the at least one counter-guide device in an installation position of the storage module in the receiving compartment is configured along at least one spatial axis, the at least one locking element being movably mounted between an unlocking position and a locking position, the at least one locking element in the unlocking position allowing removal of the at least one storage module from the at least one receiving compartment or a The at least one storage module can be accommodated in the at least one storage compartment, and the storage module in the The installation position of the memory module can be locked in a form-fitting, releasable manner by the locking element in the locking position.

The receiving compartment can be configured to be limited on at least one side, in particular by the motor vehicle. The receiving device and the receiving compartment are preferably arranged in an underbody section of the motor vehicle. The invention is described by way of example using an embodiment of the receiving device in which the storage module is inserted from below into the receiving compartment of the receiving device in the installation position of the storage module. The installation position is to be understood as the position of the storage module in the receiving device in which the storage module is positively locked with the receiving device, i.e. secured in its position, and the storage module is electrically conductively connected to the electrical connection of the receiving device, so its energy supply function is enabled. The storage module is mechanically locked on the receiving device by means of the mechanical interface of the receiving device. For this purpose, the mechanical interface has at least one guide device and at least one locking element. In the exemplary embodiment in which the invention is described, the at least one guide device is screwed and / or welded to the body of the motor vehicle and / or constructed in some other way. The at least one guide device is described by way of example as a guide groove and / or link guide. The at least one counter-guide device of the storage module is described by way of example as a bolt and / or other structural elements protruding from the storage module for guidance in the at least one guide device. Of course, the configuration of the guide device and the counter-guide device can also be configured the other way round, so that the storage module comprises at least one guide groove and the receiving device comprises the at least one guide element, such as a bolt, for guiding in the guide groove. As shown in detail in the following sections, the receiving device advantageously has at least one guide device, in particular a plurality of guide devices, on one side of the receiving compartment, in particular on several sides of the receiving compartment. The guide devices according to the invention are particularly advantageous since the at least one guide device is designed to block a movement of the at least one counter-guide device in an installation position of the storage module in the receiving compartment along at least one spatial axis. Thus, a guide device of the receiving device is designed in each case to the Restrict movement of the memory module in at least two degrees of freedom.

The spatial axes are to be defined within the scope of the invention using the example of the motor vehicle according to the invention, the recording system and at least one storage module being arranged along a floor area of the motor vehicle. The X-axis corresponds to the directions of travel of the motor vehicle, the Y-axis corresponds to the lateral directions of the motor vehicle and the Z-axis corresponds to the upward and downward directions in relation to the exemplary embodiment of the motor vehicle.

The mechanical interface further comprises at least one locking element which is movably mounted between an unlocking position and a locking position. The device according to the invention preferably provides a device for the form-fitting, releasable locking of a memory module from the interaction of the elements of the mechanical interface, the at least one guide device and the at least one locking element. The locking element is preferably designed to block a movement of the storage module in the receiving compartment, in particular in the installation 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 locking position. The clamping force can be made possible by a spring device, a pneumatic device, a hydraulic device and / or another clamping device of the receiving device and / or of the motor vehicle. A storage module according to the invention is preferably guided into the receiving device via the at least one guide device for guiding at least one counter-guide device of the storage module. The memory module is then locked in a form-fitting, releasable manner by moving the locking element between the unlocking position and the locking position. The fastening element thus enables a second form-fitting coupling with the storage module, in particular with the external geometry of the storage module, and thus, in combination with the guide device, a form-fitting and releasable locking of the storage module with the receiving device. As will be described in detail later on the method according to the invention, it can be advantageous to define the sequence of the form-fitting couplings. For example, it is advantageous first of all to initiate the coupling of the storage module to the guide device and then or at least in sections to generate the coupling to the locking element in parallel. To remove the storage module from the locking compartment, first the coupling of the locking element and then, or at least in sections at the same time, the coupling of the locking bolt to the storage module is advantageously released in reverse order. The storage module for electrical energy, which will be described in more detail later, is thus held in the installation position of the storage module by means of the stationary guide device and the movable locking element after it has been received in the receiving device. The receiving device according to the invention can preferably comprise at least two or more guide devices in order to enable a secure, form-fitting and releasable locking of the storage module with the receiving device, for example distributed over a larger area and / or over several force introduction points. Thus, the receiving device according to the invention advantageously enables simple, fast and in particular tool-free receiving or removal of a storage module for electrical energy in the receiving device through the combination of the at least one guide device and the at least one locking element. Thus, the receiving device according to the invention advantageously enables the at least one storage module to be removed from the at least one receiving compartment of the receiving device and / or receiving the at least one storage module in the at least one receiving compartment of the receiving device, in particular in an automated or semi-automated manner using a changing device with an interchangeable platform.

According to a preferred further development of the invention, it can be provided in a receiving device that at least one first guide device of the mechanical interface is arranged on a first longitudinal side of the receiving compartment and at least one second guide device is disposed on a second longitudinal side of the receiving compartment, in particular the first longitudinal side and the second longitudinal side are arranged parallel or substantially parallel to one another. The phrase “X or essentially X” should be understood within the scope of the invention as a possible, slight deviation, for example due to manufacturing tolerances and / or material properties, without changing the underlying, intended function of the feature. The receiving compartment preferably corresponds to the dimensions of the at least one storage module or essentially to the dimensions of the at least one storage module for an advantageous use of installation space. The storage module and the receiving compartment are usually designed as rectangular cuboids. Additionally or alternatively, the first guide device and the second guide device are arranged in one plane or in parallel planes, in particular along the X-axis and / or parallel to the Y-axis. Alternative to an exemplary Arrangement and / or extension of the guide devices from the longitudinal sides of the receiving compartment, the guide devices can, also by way of example, additionally or alternatively have an extension in the Z-axis in relation to a motor vehicle, so that the guide devices can be inserted into a corresponding storage module from above into a the counter-interface and / or counter-guide device arranged on the memory module intervene in order to enable a form-fitting coupling according to the invention. A receiving device configured in this way advantageously enables the counter-guide devices of a storage module to be guided through the guide devices of the receiving device. The guide device is preferably designed in such a way that the guide devices are undercut at least in sections by the counter-guide devices. A receiving device configured in this way enables, for example, the first guide device and the second guide device to block a movement of the at least one counter-guide device, in particular in an installation position of the storage module in the receiving compartment, along the Z spatial axis. In addition, a receiving device configured in this way can, for example, by a lateral delimitation of the first guide device and the second guide device, block a movement of the at least one counter-guide device, in particular in an installation position of the storage module in the receiving compartment, along the Y spatial axis.

According to a preferred further development of the invention, it can be provided for a receiving device that at least one third guide device of the mechanical interface is arranged on an end face of the receiving compartment, the end face being aligned in particular orthogonally or essentially orthogonally to the first long side and to the second long side. In addition or as an alternative to the first guide device and / or the second first guide device, the third guide device is arranged in a common plane or in a parallel plane, 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 allow an undercut with the counter-guide devices of the at least one storage module, the third guide device according to the invention supplements, for example, penetration of a corresponding counter-guide device, in particular along the X-axis. A receiving device configured in this way enables, for example, the third guide device to block a movement of the at least one counter-guide device, in particular in an installation position of the storage module in the receiving compartment, along the Y-axis and / or the Z-axis.

According to a preferred further development of the invention, it can be provided in a receiving device that the at least one locking element is designed in such a way that the storage module in the installation position of the storage module by the locking element in the locking position along at least one spatial axis, in particular along two spatial axes, through the at least one Locking element is positively, releasably lockable. The device according to the invention preferably provides a device for the form-fitting, releasable locking of a memory module from the interaction of the elements of the mechanical interface, the at least one guide device and the at least one locking element. The locking element is preferably designed to block a movement of the storage module in the receiving compartment, in particular in the installation position of the storage module, along the X spatial axis. The locking element can, however, additionally or alternatively, for example by engaging lugs, bolts and / or other structural components in the storage module, in particular in the installation position of the storage module, a blocking of a movement of the storage module in the receiving compartment, in particular in the installation position of the storage module, enable along the Y-spatial axis. By way of example, a storage module according to the invention is guided into the receiving device via the at least one guide device for guiding at least one counter-guide device of the storage module. Likewise, for example, the storage module is then, at the same time or at least in sections at the same time, positively and releasably locked by a movement of the locking element between the unlocking position and the locking position. The receiving device designed in this way is particularly advantageous since it is particularly easy to accommodate the at least one storage module in the at least one receiving compartment of the receiving device and a form-fitting, releasable locking, in particular automated or partially automated by a changing device with a changing platform.

According to a preferred further development of the invention, in a receiving device it can be provided that the at least one guide device has a first guide section and a second guide section, the first guide section introducing the at least one counter-guide device into the guide device and the second guide section providing an undercut of the guide device through the at least one Counter guide device allows. The first guide section advantageously enables the counter-guide device to be introduced into the guide device. For example, the counter-guide devices of a storage module are introduced from below into the at least one guide device of the receiving device, in particular in the direction of the Z-axis. A movement of the counter-guide devices along the second guide section, in particular in the direction of the X-axis, enables the guide device to be undercut by the at least one counter-guide device. The first guide section and the second guide section are designed together and / or merge into one another. The guide sections are preferably arranged at an angle, in particular 90 ° or essentially 90 °, to one another. The first guide section preferably has a conical configuration, at least in sections, so that introduction of the counter-guide devices 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 counter guide devices of the storage module. Preferably, the first guide section and the second guide section represent sections of a single guide groove and / or a guide slot. For example, a receiving device configured in this way enables an automated or partially automated insertion of a storage module by, for example, a changing device with a changing platform and thus fulfills the task according to the invention particularly advantageously.

According to a preferred further development of the invention, it can be provided in a receiving device that the at least one locking element is mounted so as to be linearly movable between an unlocking position and a locking position along a locking axis and / or rotatable about a locking axis. The locking element can be linearly movable and / or rotatably mounted about a locking axis in order to enable the form-fitting, releasable locking of the storage module in the installation position in the receiving device. Both in the case of a linear movement and in the case of a rotary movement, the locking element can enable locking on the outside of the memory module or at least partially engage in the memory module and / or in a recess in the memory module. A locking element configured in this way is particularly advantageous since it enables secure, form-fitting and releasable locking of the storage module in the receiving device with simple means.

According to a preferred further development of the invention, it can be provided in a receiving device that the receiving device has a sensor device and a control device, the sensor device being designed to detect a position of the memory module in the at least one receiving compartment, the control device for controlling the movement of the locking element between the unlocking position and the locking position, in particular on the basis of the detected position of the memory module by the sensor device. As an alternative or in addition to the clamping device described above, the movement of the locking element can be controlled by a control device. The movement of the locking element is advantageously controlled by a control device on the basis of the detected position of the memory module by the sensor device, so that when a memory module is detected in the installation position of the memory module, the locking element is moved into the locking position by the control device and thus a positive locking of the memory module with the recording device, in particular automated, allows.

According to a second aspect of the invention, the object is achieved by a memory module for receiving in a receiving device according to the first aspect.

The mechanical interface 12th is as two parallel guide devices 14th in the form of parallel link guides with a first guide section 15th and a second guide section 16 designed. The counter guiding devices 34 of the storage module are designed as cylinders and penetrate along the penetration axis EA into the guiding devices 14th one. The first guide section 15th is conical in order to simplify the penetration. By moving the memory module 30th along the undercut axis HA become the guiding devices 14th of the Counterguide devices 34 undercut and the frontal counter guide devices 34 on the first face 44 of the storage module penetrate the front guide devices 14th the receiving device 1 one. The electrical connection makes contact 18th the receiving device 1 with the electrical mating connection 38 and enables the stored electrical energy to be provided from the storage module 30th to the receiving device 1 and / or to a higher-level system such as a motor vehicle 60 (Not shown).
