Description

Prior ArtThe invention relates to an arrangement having a cooling module and a fastening device for fastening a cooling module of a motor vehicle serving for a battery, and to such a fastening device. The invention relates in particular to the field of passenger cars (cars) and trucks (trucks).A battery for a motor vehicle is known from DE 10 2011 000 572 A1, wherein a cooling module is provided for cooling the battery cells. In this case, the battery comprises a plurality of battery modules. The battery modules and the cooling module are joined together to form a battery box with the aid of plug connections.For fastening a cooling device, it is furthermore conceivable for the cooling module to be connected to a body of the motor vehicle by screw connections.In a conventional embodiment, units such as pumps, valves and surge tanks mounted in the engine compartment of a combustion vehicle can be supplied to an automobile manufacturer as self-operating units. The latter can then install these supply parts in its vehicle, hose them, i.e. connect them to the cooling circuit, and connect them to the electrical interfaces provided for this purpose. This process entails a considerable amount of handling at the automobile manufacturer. On the other hand, depending on the number of units which are hosed, numerous hoses which are laid through and transversely in the engine compartment can be required. Depending on the application of the vehicle, it may often happen that the construction spaces in the vehicle are so narrow and difficult to reach, in particular angled, that the mounting of these assemblies and their hose connection is a significant challenge.With the introduction of the electric vehicles and thus the elimination of the combustion engine, there is generally now more installation space in the engine compartment of an electric vehicle which is sufficiently large to install a central unit (FTU, which stands for "flexible thermal unit" (flexible thermal unit)). The FTU can consist of pumps, valves, sensors, in particular temperature and fill level sensors, compensation containers and wiring board. This central unit can be provided ready by an automobile supplier, for example, so that the automobile manufacturer can mount and fix it in his vehicle.Disclosure of the InventionThe fastening device according to the invention having the features of the main claim and the arrangement having the features of claim 11 have the advantage that an improved configuration and mode of operation are made possible.

In particular, the arrangement according to the invention with the cooling module and the fastening device can also be produced and distributed independently of a battery, in particular a drive battery of a motor vehicle.The body connecting element and the cooling module connecting element can be based on a connecting element which can be used both as a body connecting element and as a cooling module connecting element. Furthermore, the first fastening recess and the second fastening recess can optionally be fixed with respect to the respective application. For example, the locking body can be designed symmetrically such that, depending on the installation position, one of its fastening recesses can serve as a first fastening recess for the vehicle body connection element and its other fastening recesses can serve as a second fastening recess. Furthermore, a locking body can optionally also have more than two fastening recesses.

A partial or complete counterbore of the hook in its mounting position under the outer surface of the locking body can be made possible.It is advantageous that the second fastening recess has at least one counterbore on an outer surface of the locking body, into which counterbore the through-opening of the second fastening recess opens and which surrounds the through-opening of the second fastening recess at least partially circumferentially, and that the cooling module connection element has at least one hook, with which the cooling module connection element engages behind the locking body on the counterbore of the second fastening recess. Corresponding advantages can be achieved in the case of the cooling module connection element, as in the case of the vehicle body connection element. If a plurality of hooks are provided, then one or more depressions can, however, also be provided in a targeted manner for one or more hooks in order to achieve adaptations to the respective application.It is advantageous that a cross section of the counterbore of the first fastening recess is at least approximately circular and / or that the counterbore of the first fastening recess is arranged offset relative to the through opening of the first fastening recess such that a support surface for the hook of the vehicle body connecting element is formed. In this way, a grasp behind can be improved. In particular, the counterbore can be adapted to the geometry of the hook. As a result, in particular the support surface formed by the counterbore can be adapted to the hook. The counterbore can be formed so large that the hook is at least substantially countersunk.It is advantageous that a cross section of the counterbore of the second fastening recess is at least approximately circular and / or that the counterbore of the second fastening recess is arranged offset relative to the through opening of the first fastening recess such that a support surface for the hook of the cooling module connection element is formed. Corresponding advantages as in the case of the vehicle body connection element can thus be realized.It is advantageous that the body connecting element has at least one clamp based on a U-shaped basic shape, which clamp has a first rod-shaped leg and a second rod-shaped leg, that the first rod-shaped leg of the body connecting element extends at least partially through the through-opening of the first fastening recess in the assembled state, that the second rod-shaped leg of the body connecting element extends through a further through-opening of the first fastening recess in the assembled state, and that the clamp of the body connecting element engages around a web of the locking body provided between the through-opening and the further through-opening of the first fastening recess in the assembled state, preferably at least partially resting, in particular resting at least partially free of play. This can improve the stability of the connection. An advantageous damping of oscillations can be improved.It is advantageous that the cooling module connection element has at least one clamp based on a U-shaped basic shape, which clamp has a first rod-shaped leg and a second rod-shaped leg, that the first rod-shaped leg of the cooling module connection element extends at least partially through the through-opening of the second fastening recess in the assembled state, that the second rod-shaped leg of the cooling module connection element extends through a further through-opening of the second fastening recess in the assembled state, and that the clamp of the cooling module connection element engages around a web of the locking body provided between the through-opening and the further through-opening of the second fastening recess in the assembled state, preferably at least partially resting, in particular resting at least partially without play. Corresponding advantages as in the case of the vehicle body connection element can thus be achieved.It is advantageous that the body connecting element and the web of the locking body provided in the first fastening recess are configured to be adapted to one another such that, in the mounted state, the web of the locking body provided in the first fastening recess limits insertion of the body connecting element. As a result, a defined insertion position can be defined. Thus, an advantageous mode of operation after assembly is reliably ensured. Assembly can be simplified.It is advantageous that the cooling module connecting element and the web of the locking body provided in the second fastening recess are configured to be adapted to one another such that, in the mounted state, the web of the locking body provided in the second fastening recess limits insertion of the cooling module connecting element. Corresponding advantages as in the case of the vehicle body connection element can thus be achieved.It is advantageous that a hook is provided at one end of the first rod-shaped leg of the vehicle body connection element and / or that a hook is provided at one end of the second rod-shaped leg of the vehicle body connection element. Thus, the hook can be positioned advantageously. By surrounding the legs of the body connecting element and the interaction between the web and the U-shaped clamp, a connection which is restricted with respect to the three degrees of translational freedom can also be created. The U-shaped bracket limits the remaining rotational freedom. This allows reliable fastening, which can also be implemented in a damped manner.It is advantageous that a hook is formed at an end of the first rod-shaped leg of the cooling module connection element and / or that a hook is formed at an end of the second rod-shaped leg of the cooling module connection element. Corresponding advantages as in the case of the vehicle body connection element can thus be achieved.It is advantageous that the first rod-shaped leg of the body connecting element has a cross section which comprises a partial ring profile and / or a U profile, and / or that the second rod-shaped leg of the body connecting element has a cross section which comprises a partial ring profile and / or a U profile. As a result, a connection can be further optimized. In particular, the leg can support rotational forces over its preferably entire length on the locking body in this way.It is advantageous that the first rod-shaped leg of the cooling module connection element has a cross section which comprises a partial ring profile and / or a U profile, and / or that the second rod-shaped leg of the cooling module connection element has a cross section which comprises a partial ring profile and / or a U profile. Corresponding advantages as in the case of the vehicle body connection element can thus be achieved.It is advantageous that the body connecting element has a connecting part which connects the first rod-shaped leg of the body connecting element to the second rod-shaped leg of the body connecting element, and that the partial ring profile or the U profile of the cross section of the first rod-shaped leg of the body connecting element or the partial ring profile or the U profile of the cross section of the second rod-shaped leg of the body connecting element continues via the connecting part in the direction of the extension of the first rod-shaped leg of the body connecting element or of the second rod-shaped leg of the body connecting element. As a result, a certain form fit can be created between the respective leg and the locking body over preferably at least substantially the entire leg and preferably at least substantially the connecting part. Thus, a connection can be further optimized.It is advantageous that the cooling module connection element has a connecting part which connects the first rod-shaped leg of the cooling module connection element to the second rod-shaped leg of the cooling module connection element, and that the partial ring profile or the U profile of the cross section of the first rod-shaped leg of the cooling module connection element or the partial ring profile or the U profile of the cross section of the second rod-shaped leg of the cooling module connection element continues via the connecting part in the direction of the extension of the first rod-shaped leg of the cooling module connection element or of the second rod-shaped leg of the cooling module connection element. Corresponding advantages as in the case of the vehicle body connection element can thus be achieved.It is advantageous that the locking body in the mounted state encloses the body connection element on its lateral surface at least substantially without play and / or that the locking body in the mounted state encloses the cooling module connection element at least substantially resting on its lateral surface, in particular resting without play. A large-area contact can thus be realized, so that, for example, an advantageous damping is possible.It is advantageous that the locking body is based on a cuboidal, in particular cubic, basic shape. A compact configuration is thereby possible.It is advantageous that the locking body is designed such that the body connection element can be introduced from a side surface of the locking body during assembly and that the cooling module connection element can be introduced into the locking body with a different orientation and / or from a different orientation of a further side surface of the locking body, in particular from a further side surface facing away from the side surface of the locking body. This allows an advantageous orientation of the locking body and of the cooling module with respect to the body.In another advantageous embodiment, it is advantageous that the locking body is designed such that the body connection element and the cooling module connection element can be inserted during assembly with at least approximately the same orientation and / or from the same side surface of the locking body. This allows adaptation to specific application cases.Especially in an arrangement with at least one cooling module, which serves for cooling at least one battery of a motor vehicle, in particular a drive battery, it is advantageous that a decoupled screw connection is provided, via which the cooling module can be connected to the body for restricting at least one linear degree of freedom, and / or that at least one decoupled screw connection is provided, via which the cooling module can be connected to the body for restricting at least one rotational degree of freedom. Depending on the configuration, this can be used to realize, for example, the advantage that a reduction of the fixing elements takes place around a screw connection.Depending on the configuration, one or more of the following features and advantages can be realized.A fastening concept can be realized in which the number of parts can be reduced. For example, in a conventional FTU, at least three screws are required on a decoupling element. The functions of a rubber buffer and of a sheet metal bushing on the module / distributor can be put together.An improved degree of freedom or tolerance adjustment can be effected if, for example, one of the three screw fixations is replaced by a proposed fastening device with a locking body, in particular a locking rubber.A locking body can be formed at least substantially from a synthetic rubber. Specifically, the locking body may be formed at least substantially of a synthetic rubber having a saturated main chain. In particular, the locking body can be formed at least substantially from an ethylene-propylene-diene rubber (EPDM). This allows an advantageous configuration that can absorb vibrations. In particular, damping of such vibrations is possible.However, the locking body can also be based only on the materials mentioned and can optionally be formed from further materials, in particular a material combination. Furthermore, a configuration of other materials, in particular those comparable to EPDM, is also possible.An interface on the side assigned to the module can be an opening in the locking body, wherein the module can have the countergeometry in the form of the connection element. However, the connection element can also be an independent component which is connected to the cooling module.The locking body can be inserted onto a collar of the connection element. On a side of the locking body assigned to the connection to the vehicle body, which side may or may not be different from the side assigned to the cooling module, the same interface geometry may be located in an advantageous embodiment, so that, for example, a plugging on to a vehicle geometry, which has the connection element in this respect, is possible. The connection element to the vehicle geometry can, however, also be an independent component which is connected to the vehicle geometry.At least one of the interfaces on the locking body contains small pockets in order to ensure a locking with the module or a body part. In this case, a hook geometry is preferably used.The assembly process during the construction of the FTU in the vehicle takes place, for example, with the following steps: in a first step, the locking body can be inserted onto the connection element on the vehicle body until it abuts. In this case, a latching geometry can penetrate through the locking body.In a second step, a fastening from a standard decoupling element can be effected by a screw in order to lock the system. In a third step, a fastening of a further and last standard decoupling system can be effected by a screw in order to eliminate a possible rotation and thus the last degrees of freedom.Depending on the configuration, one or more of the following advantages can be realized: the assembly effort of the FTU at the end customer can be lower. A reduction of the fixing elements, in particular around a screw and a steel bushing, is possible. Assembly of the FTU can be performed more quickly. Costs can be saved. Due to the geometry of the locking body, the vibrations and / or movements on the system can be significantly reduced.Brief Description of the DrawingsPreferred exemplary embodiments of the invention are explained in more detail in the following description with reference to the attached drawings, in which corresponding elements are provided with corresponding reference numerals.
