Description

Technical Field

[0001] The invention relates to a holder / carrier for mounting at least one electric energy storage device on a frame of a commercial vehicle according to the preamble of claim 1 . Background Art

[0002] CN 211195826 U discloses a fixing bracket device for a vehicle battery. In addition, CN 216153582 U discloses a frame for an accumulator. Summary of the invention

[0003] The object of the present invention is to provide a mount for mounting at least one electric energy storage device on a frame of a commercial vehicle in order to achieve particularly advantageous accident response characteristics.

[0004] This object is achieved by a support having the features of claim 1. Advantageous embodiments of the invention with suitable refinements are indicated in the remaining claims.

[0005] The present invention relates to a support (also referred to as a supporting device) for placing and thus carrying at least one accumulator on a frame, especially designed as a ladder frame, of a commercial vehicle, especially a truck. This means that the commercial vehicle has an accumulator, a frame and a support in its finished state. The accumulator has been or will be placed on the frame by the support, especially in the following way, that is, the accumulator is held on the support and the support is held on the frame. With the help of the accumulator, electrical energy can be stored in an electrochemical manner. In particular, the accumulator is a high-voltage component, and its voltage, in particular, the operating voltage or the rated voltage is preferably greater than 50 volts, in particular greater than 60 volts, and more preferably several hundred volts. The commercial vehicle is designed as a motor vehicle and is also referred to as a vehicle for short, and can be an electric vehicle or a hybrid vehicle. In particular, the commercial vehicle can be a battery electric vehicle or a fuel cell vehicle. The commercial vehicle, also referred to as a motor vehicle, has at least one motor that can drive the commercial vehicle in particular purely electrically in its finished state. Here, the motor can be supplied with electrical energy that has been or will be stored in the accumulator, so that the motor can be operated in motor mode and therefore as an electric motor. With the help of the electric motor, the motor vehicle can be driven in particular purely electrically.

[0006] The support has a receiving area. In particular, the receiving area is particularly directly delimited by the support. The battery can be or is already fixed to the support. Furthermore, the battery can be or is already accommodated in the receiving area. This means that the battery is already accommodated in the receiving area in the finished state of the commercial vehicle, wherein the battery is already fixed to the support. In particular, it is conceivable that the battery can be or is already fixed to the support in the receiving area. Thus, the battery can be or is already fixed to the vehicle frame by means of the support and thus will be or is already placed on the vehicle frame.

[0007] In order to achieve particularly advantageous accident response characteristics and thus particularly high safety, the invention now provides that the support has an underframe which can be mounted on the vehicle frame and is therefore designed to be separate from the vehicle frame, which can be or is already fastened to the vehicle frame of the commercial vehicle, also referred to as the vehicle frame. Furthermore, in the mounted state of the support, the underframe delimits the accommodation area downwards, in particular directly, in the vehicle height direction of the commercial vehicle. Here, the support is in its mounted state in the finished state of the commercial vehicle equipped with the support. This means that in the mounted state of the support and therefore in the finished state of the commercial vehicle, the support is already fastened to the vehicle frame, wherein in particular the underframe is mounted and fastened to the vehicle frame in particular directly.

[0008] The support further comprises a support box which is designed to be separate from the underframe and thus also from the vehicle frame (vehicle frame), which is arranged on the underframe, in particular when viewed in the vehicle height direction of the commercial vehicle, and which in the mounted state of the support delimits the accommodation area in the vehicle transverse direction, in particular directly and in particular on both sides. In the mounted state of the support, the support box is supported rearwardly on the underframe in the longitudinal direction of the vehicle by a bracket (konsole). In addition, the support box is fixed to the underframe by the bracket. For this purpose, the bracket is designed to tilt / fold backward in the longitudinal direction of the vehicle and thereby allow an accident-induced movement of the support box rearward in the longitudinal direction of the vehicle in the event of an accident-induced force acting rearwardly (i.e. from front to rear) in the longitudinal direction of the vehicle, thus enabling an accident-induced rearward displacement of the support box. In other words, if an accident causes an application of forces acting on the commercial vehicle and therefore in particular on the support from the front to the rear in the longitudinal direction of the vehicle and caused, for example, by a frontal collision of the commercial vehicle, the support is tilted rearwards in particular relative to the underframe in the longitudinal direction of the vehicle and thereby allows a movement of the support box rearwards in the longitudinal direction of the vehicle and relative to the underframe and preferably also relative to the vehicle frame.

[0009] For example, the commercial vehicle in its manufactured state has a body structure which adjoins the support forward in the longitudinal direction of the vehicle and is in particular designed as a driver's cab and is designed to be separate from the vehicle frame and separate from the support and in particular mounted on the vehicle frame. In particular, when the body structure is the driver's cab, a person (for example, a commercial vehicle driver) can, for example, stay in the driver's cab (the body structure) in particular during the travel of the commercial vehicle. In the event of the above-mentioned accident-induced forces acting backward in the longitudinal direction of the vehicle, the bracket allows the support box, which is designed as a tower structure or forms a tower structure, to move backward in the longitudinal direction of the vehicle away from the body structure, since the bracket tilts away backward in the longitudinal direction of the vehicle and thus allows the accident-induced backward movement of the support box. In this way, for example, unnecessary excessive interactions between the support box and the body structure can be avoided in the event of accident-induced forces. In particular, excessive deformations of the driver's cab or the body structure due to the accident can be avoided, so that a very high level of safety can be achieved. The invention thus allows the geometry to be deliberately utilized to produce kinematic effects, which in particular include that when the above-mentioned accident-induced forces occur, the bracket flips backwards in the longitudinal direction of the vehicle, in particular flips away, thereby allowing the support box to move, in particular flip, backwards in the longitudinal direction of the vehicle and in particular away from the body structure. In other words, for example, when the above-mentioned accident-induced forces occur, which act from front to rear in the longitudinal direction of the vehicle, the support box can also flip backwards in the longitudinal direction of the vehicle due to the tilting of the bracket in the longitudinal direction of the vehicle. The bracket thus forms an economical and space-saving crash structure, by means of which favorable accident response characteristics can be achieved.

[0010] In an advantageous embodiment of the invention, the support box is supported in the mounted state of the bracket in the longitudinal direction of the commercial vehicle on a front stop rail arranged on the underframe. Unintentional movements of the support box can thereby be avoided. In particular, in the event of an accident-induced application of forces, it can thereby be ensured that the support box moves in a particularly advantageous manner, in particular from the front to the rear in the longitudinal direction of the vehicle, so that a particularly high level of safety can be achieved.

[0011] Another embodiment is characterized in that the support box is arranged between the front limiting rail and the rear bracket, especially when viewed in the longitudinal direction of the vehicle, so that a particularly advantageous movement of the support box, in particular a rearward displacement, can be achieved in the event of accident-induced forces, thereby achieving a particularly high level of safety.

[0012] A second aspect is also disclosed which is independent but can be combined with the support according to the invention or an embodiment thereof. In the second aspect, the underframe has a longitudinal extension direction which, in the mounted state of the support, extends in the vehicle transverse direction of the commercial vehicle. This means in particular that the underframe has a first extension extending in the vehicle transverse direction, a second extension extending in the vehicle longitudinal direction and a third extension extending in the vehicle height direction, wherein the first extension is greater than the second extension and greater than the third extension, so that the first extension is the longitudinal extension of the underframe, which extends in the vehicle transverse direction and therefore in the longitudinal extension direction. In this case, for example, the support box has side parts which are spaced apart from each other in the longitudinal extension direction of the underframe and which, in the mounted state of the support, delimit the accommodation area in the vehicle transverse direction.

[0013] One embodiment of the second aspect is characterized in that the bearing box has at least one support rod which delimits the accommodation area in the longitudinal direction of the vehicle to the front or rear in the mounted state of the support, and the support rod is designed to be separate from the side parts and connected to the side parts. This makes it possible to achieve a high rigidity of the support, for example, as described above, which forms a tower structure, in a particularly light manner.

[0014] A further embodiment of the second aspect provides that the support rod, in the installed state of the bracket, extends obliquely to the vehicle transverse direction and obliquely to the vehicle height direction in a plane defined by the vehicle transverse direction and the vehicle height direction.

[0015] A further embodiment of the second aspect is characterized in that each side part has intersecting support elements which delimit a triangular through-opening of the corresponding side part.

[0016] A third aspect, which is particularly independent, relates to a modular system for a plurality of structural variants of a support according to the second aspect. The modular system according to the third aspect has an undercarriage in the form of an undercarriage common to the various structural variants and a plurality of support frames, which can be connected to one another or to the undercarriage and can be stacked in the vehicle height direction in the mounted state of the support and define respective accommodation areas for the respective energy storage devices. The above and below descriptions of the support box of the support according to the invention and the support box of the support according to the second aspect can also be directly applied to the corresponding support frames of the modular system according to the third aspect, and vice versa.

[0017] The fourth aspect, which is particularly independent, provides that the support box, which is formed separately from the chassis, is arranged on the chassis and defines a storage area in the transverse direction of the vehicle when the bracket is installed, is supported forward in the longitudinal direction of the vehicle on a front limiting rail provided on the chassis, especially in the installed state of the bracket, and is thereby positioned relative to the chassis, and is fixed to the chassis via a bracket provided at the rear of the chassis and via the limiting rail. Here, the above and below descriptions of the bracket of the bracket according to the present invention can also be directly applied to the bracket of the fourth aspect, and vice versa, and the above and below descriptions of the limiting rail of the front part of the bracket according to the present invention can also be directly applied to the limiting rail of the fourth aspect, and vice versa.

[0018] An embodiment of the fourth aspect is characterized in that, in particular when viewed in the longitudinal direction of the commercial vehicle, the support box is arranged between a front limiting rail and a rear bracket.

[0019] In another embodiment of the fourth aspect, the support has a second support frame, which defines a second receiving area for the second battery. The second support frame of the fourth aspect is designed to be separate from the base frame and separate from the first support box of the fourth aspect, and is arranged, in particular inserted, on the first support frame of the fourth aspect, in particular stacked and inserted into each other in the manner of two beverage boxes.

[0020] It has proven to be particularly advantageous here if the first bearing box and the second bearing box of the fourth aspect are designed to be structurally identical to one another.

[0021] The second and third aspects allow the placement of force transmission paths and accumulators in the outer region of a commercial vehicle, also referred to as a vehicle, and the introduction of forces into the vehicle frame via the underframe, also referred to as the underframe. This allows a particularly high support stiffness to be achieved, in principle, by means of an optimized triangular structure, which can be achieved in particular by means of supporting elements. As a result, the support structure space requirement can be kept particularly low, in particular in the longitudinal direction of the vehicle, so that a particularly short wheelbase of a commercial vehicle can be achieved. In addition, a modular construction of the support can be achieved, so that a highly variable structure, i.e. different structural variants of the support, can be achieved in a particularly economical manner. Thus, for example, at least or exactly one accumulator, in particular one to three accumulators, can be positioned, i.e. placed on the vehicle frame, with a particularly low structural space requirement and material consumption.

[0022] The energy storage device is preferably a battery, in particular a high-voltage battery.

[0023] In a fourth aspect, the front stop rail is a front stop, wherein the rear bracket can be, for example, a tension bracket. The chassis, also referred to as the bottom bracket, equipped with the front stop and the rear bracket allows at least almost load-free and easy installation and positioning, especially when tolerance compensation is carried out at the same time. In addition, the storage battery, which is designed as a high-voltage battery, can be easily positioned, for example, by the plug-in principle, in particular in the manner described, that is, the support boxes are stacked on top of each other and simultaneously engage with each other or plug into each other. For example, the support boxes stacked on top of each other and plugged into each other can be installed, especially on a production line, especially via externally accessible threaded areas, so that at least almost any number of storage batteries can be installed modularly, especially in a manner independent of the production process. Therefore, the fourth aspect allows easy and economical positioning and installation of at least one or more storage batteries, especially in the vehicle height direction, located above the vehicle frame, which is especially designed as a ladder frame.

[0035] Figure 1 The schematic front perspective view shows a support 10 of a commercial vehicle, which is also referred to as a vehicle for short, and which is also referred to as a support device or is designed as a support device. This means that the commercial vehicle has the support 10 in its finished state. In addition, the commercial vehicle has Figure 1 The frame 12 shown partially in the figure is designed as a ladder frame and is also referred to as a vehicle frame. The frame 12 (vehicle frame) has two longitudinal beams 14 and 16 which are spaced apart from each other in the vehicle transverse direction of the commercial vehicle and whose respective longitudinal extension direction extends in the vehicle longitudinal direction of the commercial vehicle. Figure 1 As shown by the double arrow 18, the vehicle longitudinal direction of the commercial vehicle is Figure 1 The bracket 10 is at least indirectly, in particular directly, fixed to the vehicle frame 12, in particular in such a way that the bracket 10 is at least indirectly, in particular directly, fixed to the longitudinal beams 14 and 16. For example, the vehicle frame 12 has at least one Figure 1 A crossbeam (not shown) is provided in the drawing, by which the longitudinal beams 14 and 16 are connected to one another, in particular in such a way that the crossbeam is fastened to the longitudinal beams 14 and 16 , in particular at both ends.

[0036] The support 10 has receiving areas 22 and 24, which are respectively delimited in particular directly by the support 10. A corresponding energy storage device 26, 28 is arranged in each receiving area 22, 24 and is therefore accommodated. The energy storage device 26, 28 is in particular directly fixed to the support 10, so that the energy storage device 26, 28 is placed and thus held on the vehicle frame 12 by the support 10, in particular by means of the support 10. The energy storage device 26, 28 is preferably designed as a high-voltage component. In particular, the energy storage device 26, 28 is preferably designed as a battery, in particular a high-voltage battery.

[0037] Combination Figures 2 to 4It can be seen that the support 10, which is designed separately from the vehicle frame 12, has a base frame 30, which is arranged on the vehicle frame (frame 12), is fixed to the vehicle frame 12 (especially the longitudinal beams 14 and 16) and delimits the receiving area 24 in the vehicle height direction of the commercial vehicle, especially directly downward, which is also called the base support. In addition, the support 10 has at least or exactly two supporting boxes 32 and 34, which are independent of each other and are each designed separately from the base frame 30, wherein each supporting box 32, 34 is also called a supporting frame or is designed as a supporting frame. It can be seen that the receiving area 24 is delimited downward, especially directly, by the base frame 30 in the vehicle height direction of the commercial vehicle in the installed state of the support 10. The support 10 is in its installed state in the finished state of the commercial vehicle equipped with the support 10, wherein the figure shows the installed state of the support 10. The double arrow 36 shows the vehicle height direction of the commercial vehicle.

[0038] In particular, in the mounted state of the bracket 10, the support box 34 is placed, in particular directly, on the underframe 30 from top to bottom in the vehicle height direction, and is thus arranged on the underframe 30. The support box 34 delimits the accommodation area 24 on both sides (i.e., to the left and to the right) in the vehicle transverse direction. In addition, the support box 34 delimits the accommodation area 24 on both sides (i.e., to the front and to the rear) in the vehicle longitudinal direction. It can be seen that the support box 32 is placed on the support box 34 in the vehicle height direction and is therefore arranged on the support box 34, so that the support box 34 is arranged between the support box 32 and the underframe 30 in the vehicle height direction.

[0039] from Figure 2 , Figure 3 and Figure 4 It can be clearly seen that the support box 34 is supported rearwardly on the underframe 30 in the longitudinal direction of the vehicle (double arrow 20) via brackets 38, wherein the brackets 38 are spaced apart from one another in the transverse direction of the vehicle and thus in the longitudinal extension direction of the underframe 30 and the respective support box 32, 34. Furthermore, the support box 34 is fastened to the underframe 30 via the brackets 38, in particular in such a way that the support box 34 is fastened to the underframe 30, in particular directly, via the brackets 38 and / or the brackets 38 are fastened to the underframe, in particular directly.

[0040] from Figure 3 and Figure 4 It can be clearly seen that the bracket 38 is designed to: when an accident causes a force acting from front to rear in the longitudinal direction of the vehicle and Figure 3 When the force is applied as indicated by arrow 40, the support box 34 is tilted backward in the longitudinal direction of the vehicle, thereby allowing and thus achieving the support box 34 in Figure 4 The movement in the longitudinal direction of the vehicle, which is indicated by arrow 42 and is designed in particular as a rotational movement, is rearward.

[0041] Figure 3An obstacle is shown at 44. For example, in the event of a head-on collision, the commercial vehicle hits the obstacle 44 head-on, resulting in the application of forces caused by the accident as shown by arrow 40. Figure 3 It can also be seen that the commercial vehicle, for example, in its finished state, has a body structure in the form of a cab 46, which is designed to be separate from the support 10 and the frame 12 and is mounted on the frame 12. The cab 46 is also referred to as a driver's cabin. For example, due to a frontal collision, i.e., due to the accident-induced forces caused by the frontal collision, the cab 46 is displaced rearward in the longitudinal direction of the vehicle, in particular relative to the frame 12, wherein the accident-induced rearward movement of the cab 46 is Figure 3 In the figure, it is indicated by arrow 48. In addition, Figure 3 It can also be seen that the support 10 adjoins the driver's cab 46 in the longitudinal direction of the vehicle (double arrow 20). In order to avoid an excessively strong collision between the driver's cab 46 and the support 10 and thus to avoid excessive loading of the driver's cab 46 and thus excessive deformation of the driver's cab 46, for example, in the event of an accident-induced force, the support 38 is tilted away in the longitudinal direction of the vehicle, in particular relative to the vehicle frame 12, in the event of an accident-induced force. Thus, the support box 34, in particular the tower structure 50 consisting of the support box 34 and the support box 32 arranged thereon, tilts away in the longitudinal direction of the vehicle in the event of an accident-induced force, and / or the support box 34 or the tower structure 50 moves backward in the longitudinal direction of the vehicle in the event of an accident-induced force. In other words, the movement of the support box 34 or the tower structure 50 can be carried out in the longitudinal direction of the vehicle, away from the driver's cab 46, so that a particularly high level of safety can be achieved.

[0042] from Figure 1 and Figure 4 It can be seen that, preferably, the support box 34 is supported forward in the longitudinal direction of the vehicle, especially in the installed state of the bracket 10, on a front limiting rail 52 arranged on, especially fixed to the chassis 30, wherein, for example, the support box 34 is arranged in the longitudinal direction of the vehicle between the front limiting rail 52 and the rear bracket 38.

[0043] In the embodiment shown in the drawings, the above-mentioned longitudinal extension direction of the underframe 30 and the respective support boxes 32, 34 extends in the vehicle transverse direction. Here, the respective support boxes 32, 34 have side parts 54 and 56, which are spaced apart from each other in the longitudinal extension direction of the respective support boxes 32, 34 and therefore in the vehicle transverse direction, and which side parts delimit the respective accommodation areas 22, 24 on both sides in the vehicle transverse direction, in particular directly respectively. In addition, the respective support boxes 32, 34 have a respective front support rod 58, which delimits the respective accommodation areas 22, 24 forward in the vehicle longitudinal direction, in particular directly respectively. In addition, the respective support boxes 32, 34 have a respective rear support rod 60, which delimits the respective accommodation areas 22, 24 rearward in the vehicle longitudinal direction, in particular directly. Here, the respective support rods 58, 60 extend in a plane defined by the vehicle transverse direction and the vehicle height direction, obliquely relative to the vehicle transverse direction and obliquely relative to the vehicle height direction. A high rigidity of the respective bearing box 32, 34 can thereby be achieved in a very light manner. Furthermore, the respective side parts 54, 56 have intersecting support elements 62 which extend in particular in an X-shape and thus form an X-shape. Thus, a plurality of triangular through-holes 64 of the respective side parts 54, 56 of the respective bearing box 32, 34 are delimited by the respective support elements 62 of the respective side parts 54, 56.

[0044] In particular, the undercarriage 30 and the support boxes 32 and 34 form a modular system, by means of which different structural variants of the support 10 or the tower structure 50 can be manufactured in a very simple and economical manner. In this case, the undercarriage 30 is a common undercarriage for the various structural variants and can be used, for example, for both a first structural variant and a second structural variant of the structural variants. The support boxes 32 and 34 are support frames which can be connected to each other and to the undercarriage 30 and can be stacked in the height direction of the vehicle, in particular in the manner of water bottle boxes. In the first structural variant, for example, the undercarriage 30 and the support box 34 are used, but the support box 32 is not used, so that, for example, exactly one accumulator in the form of an accumulator 28 can be placed on the vehicle frame 12. In the second structural variant, for example, the undercarriage 30 and the support boxes 32 and 34 (such as Figure 1 and Figure 2 ), so that in particular exactly two accumulators 26 and 28 can be placed on the vehicle frame 12. Here, the support box 32 is plugged onto the support box 34, so that the support boxes 32 and 34 can be stacked on top of each other and plugged into each other like beverage boxes. In this way, the support boxes 32 and 34 can be easily stacked on top of each other and thus positioned relative to each other. For example, the support boxes 32 and 34 are connected to each other in a non-destructive way, in particular by a screw connection.

[0045] Preferably, the support box 34 is particularly directly supported on the front stop rail 52 provided on the chassis 30 and is thereby positioned relative to the chassis 30. In addition, the support box 34 is fixed to the chassis 30 via the rear bracket 38 provided on the chassis 30. In addition, the support box 34 is fixed to the chassis 30, for example, via the stop rail 52. In particular, the support boxes 32 and 34 are designed to be structurally identical to each other.

[0046] from Figure 5 It can be seen very clearly that the support rods 58 , 60 allow a particularly advantageous force transmission path to be realized in a very space-saving manner.

[0047] Figure 6 The base frame 30 is shown in a perspective schematic view. Figure 7 The support box 32 is shown in a schematic perspective view. Figure 8 The perspective view shows the support 10 with a base frame 30 and a support box 32, which is now arranged, in particular directly on the base frame 30, in particular instead of the support box 34. Finally, Fig. 9 The support boxes 32 and 34 are shown stacked directly on top of each other and plugged into each other in the manner of beverage boxes. Figure 1 and Fig. 9 As shown, the support box 32 can be placed and in particular plugged onto the support box 34 , or the support box 34 can be placed and in particular plugged onto the support box 32 , in order to produce or assemble the support 10 in a modular manner.
