[Technical Field]
[0001] The invention relates to a carrier for storing at least one electrical energy storage device in a frame of a commercial vehicle according to the preamble of claim 1. [Background technology]
[0002] No. 5,629,999 discloses a holding frame assembly for a vehicle battery.Furthermore, it can be seen that a frame for an energy storage device is known from US Pat. No. 5,629,999. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] China Utility Model No. 211195826 U [Patent Document 2] China Utility Model No. 216153582 U Summary of the Invention [Problem to be solved by the invention]
[0004] The object of the present invention is to provide a carrier for storing at least one electrical energy storage device in the frame of a commercial vehicle in such a way that particularly advantageous crash behavior can be achieved. [Means for solving the problem]
[0005] This problem is solved by a carrier having the features of claim 1. Advantageous embodiments with objective developments of the invention are presented in the further claims.
[0006] The present invention relates to a carrier, also referred to as a loading device, for storing, and therefore loading, at least one electrical energy storage device on a frame, particularly configured as a lead frame, of a commercial vehicle, particularly a lorry. This means that the commercial vehicle, in its fully manufactured state, has an electrical energy storage device, a frame, and a carrier. The electrical energy storage device is or can be stored in the frame via the carrier, particularly such that the electrical energy storage device is held in the carrier and the carrier is held in the frame. The electrical energy storage device can be used to store electrical energy, particularly electrochemically. In particular, the electrical energy storage device is a high-voltage component, and the voltage, particularly the operating voltage or nominal voltage, of the high-voltage component is preferably greater than 50 volts, particularly greater than 60 volts, and more preferably greater than 100 volts. A commercial vehicle configured as a motor vehicle, also simply referred to as a vehicle, 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. A commercial vehicle, also known as a motor vehicle, has at least one electric machine in its fully manufactured state, which can be used to drive the commercial vehicle, particularly purely electrically. In this case, the electric machine can be supplied with electrical energy that is stored or can be stored in an electrical energy storage device, so that the electric machine can be operated in motor mode, and thus as an electric motor, which can be used to drive the motor vehicle, in particular purely electrically.
[0007] The carrier has a storage area. In particular, the storage area is particularly directly defined by the carrier. The electric energy storage device can be fastened or is fastened to the carrier. In addition, the electric energy storage device can be accommodated or is accommodated in the storage area. This means that in the fully manufactured state of the commercial vehicle, the electric energy storage device is accommodated in the storage area, and the electric energy storage device is fastened to the carrier. In particular, it is considered that the electric energy storage device can be fastened or is fastened to the carrier in the storage area. Therefore, the electric energy storage device can be fastened or fastened to the frame via the carrier, and therefore can be stored or is stored in the frame.
[0008] In order to be able to achieve particularly favorable accident behavior and thus a particularly high level of safety, the carrier according to the invention has a base frame that can be mounted on the frame and is therefore configured separately from the frame, and that can be fastened or is provided so as to be fastened to the frame of the commercial vehicle, also referred to as the vehicle frame. In addition, the base frame defines a storage area, particularly directly downward in the vehicle height direction of the commercial vehicle, in the installation position of the carrier. In this case, the carrier assumes its installation position in the fully manufactured state of the commercial vehicle equipped with the carrier. This means that in the installation position of the carrier, and therefore in the fully manufactured state of the commercial vehicle, the carrier is fastened to the frame, particularly the base frame is particularly directly mounted on and fastened to the frame.
[0009] In addition, the carrier is configured separately from the base frame, and therefore also separately from the frame (vehicle frame), and has a carrier box arranged on the base frame when viewed in the vehicle height direction, particularly of a commercial vehicle, with the carrier box defining the storage area, particularly directly in the transverse direction of the vehicle at the installation position of the carrier, particularly on both sides. The carrier box is supported on the base frame via a console toward the rear in the longitudinal direction of the vehicle at the installation position of the carrier. In addition, the carrier box is fixed to the base frame via the console. The console is configured to fold backward in the longitudinal direction of the vehicle when an accident-related force is applied backward in the longitudinal direction of the vehicle, i.e., from front to rear, thereby facilitating accident-related movement of the carrier box backward in the longitudinal direction of the vehicle, and thus enabling accident-related rearward displacement of the carrier box. In other words, forces acting on the commercial vehicle from front to rear in the longitudinal direction of the vehicle, and therefore in particular on the carrier, which are relevant to an accident resulting, for example, from a frontal collision of the commercial vehicle, are applied, so that the console is folded backward in the longitudinal direction of the vehicle, in particular relative to the base frame, thereby facilitating the movement of the carrier box backward in the longitudinal direction of the vehicle relative to the base frame, preferably relative to the vehicle frame.
[0010] In its fully assembled state, the commercial vehicle has a structure, particularly configured as a cab, adjacent to the carrier, for example, toward the front in the longitudinal direction of the vehicle. The structure is configured separately from the vehicle frame and the carrier, and is particularly stored (supported) by the vehicle frame. In particular, if the structure is the cab, personnel such as the commercial vehicle driver can reside in the cab (structure), especially while the commercial vehicle is traveling. In the event of the above-mentioned accident-related forces acting rearward in the longitudinal direction of the vehicle, the console folds away from the carrier box toward the rear in the longitudinal direction of the vehicle, thereby facilitating accident-related rearward displacement of the carrier box. The console, for example, allows the carrier box, configured as or forming a tower, to move away from the structure toward the rear in the longitudinal direction of the vehicle. This makes it possible to avoid excessive and undesirable interactions between the carrier box and the structure, for example, when accident-related forces are applied. In particular, this makes it possible to avoid excessive accident-related deformations, especially of the cab or the structure, and as a result, particularly high safety can be achieved. The invention therefore makes it possible to deliberately use geometric shapes to generate kinematics which in particular allow the console to fold backward in the longitudinal direction of the vehicle, in particular to fold away, in the event of the application of the above-mentioned accident-related forces, followed by a movement, in particular folding, of the carrier box in the longitudinal direction of the vehicle backward, in particular away from the structure. In other words, for example, in the event of the application of the above-mentioned accident-related forces acting from front to rear in the longitudinal direction of the vehicle, the console will fold forward to rear in the longitudinal direction of the vehicle, which may also cause the carrier box to fold backward in the longitudinal direction of the vehicle. The console therefore forms a cost-effective and space-saving crash structure which is able to achieve advantageous accident behaviour.
[0011] In an advantageous embodiment of the invention, the carrier box is supported in the installation position of the carrier towards the front in the longitudinal direction of the commercial vehicle on a front stop rail provided on the base frame, thereby preventing undesired movements of the carrier box, and in particular ensuring particularly advantageous movements of the carrier box from front to rear in the longitudinal direction of the vehicle, especially when accident-related forces are applied, as a result of which particularly high safety can be achieved.
[0012] A further embodiment is characterized in that the carrier box is arranged between the front stop rail and the rear console, in particular when viewed in the longitudinal direction of the vehicle, so that in the event of an accident-related force a particularly advantageous movement of the carrier box, in particular a rearward displacement, can be achieved, as a result of which a particularly high level of safety can be achieved.
[0013] A second independent aspect is also disclosed, which can be combined with the carrier according to the present invention or with the carrier embodiments. In the second aspect, the base carrier has a longitudinal extension extending in the transverse direction of the commercial vehicle when the carrier is installed. This should be understood to mean, in particular, that the base frame has a first extension extending in the transverse direction, a second extension extending in the longitudinal direction, and a third extension extending in the height direction of the vehicle, the first extension being larger than the second extension and larger than the third extension, such that the first extension is a longitudinal extension of the base frame, which extends in the transverse direction and thus along the longitudinal extension. In this case, the carrier box has, for example, side elements arranged at a distance from each other in the longitudinal direction of the base frame and which define a storage area in the transverse direction when the carrier is installed.
[0014] An embodiment of the second aspect is characterized in that the carrier box has at least one strut that defines a storage area towards the front or rear in the longitudinal direction of the vehicle in the installation position of the carrier, and that this strut is formed separately from the side elements and connected to them, so that a particularly high stiffness of the carrier, for example forming the above-mentioned tower, can be achieved in a particularly weight-efficient manner.
[0015] In a further embodiment of the second aspect, it is provided that the strut extends at the installation position of the carrier obliquely to the vehicle transverse direction and obliquely to the vehicle height direction in a plane extending in the vehicle transverse direction and the vehicle height direction.
[0016] A further embodiment of the second aspect is characterized in that each side element has crisscrossing strut elements that define a triangular through opening in each side element.
[0017] A third, particularly independent, aspect relates to a kit system for multiple structural variants of the carrier according to the second aspect. The kit system according to the third aspect comprises a base frame as a cross-structural base frame common in the structural variants and multiple carrier frames, which are optionally connectable to one another and to the base frame, can be arranged one above the other in the vehicle height direction at the installation position of the carrier, and each define a respective storage area for a respective electrical energy storage device. In this case, the above and below descriptions regarding the carrier box of the carrier according to the invention and the carrier box of the carrier according to the second aspect can easily be transferred to the respective carrier frames of the kit system according to the third aspect, and vice versa.
[0018] In a particularly independent fourth embodiment, a carrier box formed separately from the base frame, arranged on the base frame, and defining a storage area in the transverse direction of the vehicle in the installation position of the carrier, is supported forward in the longitudinal direction of the vehicle in the installation position of the carrier by a front stop rail provided on the base frame, in particular, so that the carrier box is positioned relative to the base frame and is fixed to the base frame via a rear console provided on the base frame and via the stop rail. The above and below descriptions regarding the console of the carrier according to the present invention can be easily transferred to the console of the fourth embodiment, and vice versa, and the above and below descriptions regarding the front stop rail of the carrier according to the present invention can be easily transferred to the stop rail of the fourth embodiment, and vice versa.
[0019] An embodiment of the fourth aspect is characterized in that, in particular when viewed in the longitudinal direction of the commercial vehicle, the carrier box is arranged between the front stop rail and the rear console.
[0020] In a further embodiment of the fourth aspect, the carrier comprises a second carrier frame defining a second accommodation area for a second electrical energy storage device. The second carrier frame of the fourth aspect is configured separately from the base frame and separately from the first carrier box of the fourth aspect and is resting on, in particular interleaved with, the first carrier frame of the fourth aspect, in particular such that two beverage crates are stacked on top of each other and fit relative to each other.
[0021] In that case, it has proven to be particularly advantageous if the first carrier box and the second carrier box of the fourth aspect are constructed of the same structure.
[0022] The second and third aspects of the present invention allow for the provision of a force absorption path and an electric energy storage device in the outer region of a commercial vehicle, also referred to simply as the vehicle, and for the forces to be guided to the vehicle frame via a base frame, also referred to as the base carrier. This allows for particularly high rigidity of the carrier, primarily through an intelligent triangular structure, which can be realized in particular by strut elements. This allows for particularly low installation space requirements for the carrier, especially in the longitudinal direction of the vehicle, and thus allows for particularly short wheelbases of commercial vehicles. In addition, a modular configuration of the carrier allows for a highly variable design, i.e., for various structural variations of the carrier, to be achieved in a particularly cost-effective manner. Thus, for example, at least one or exactly one electric energy storage device, especially one to three energy storage devices, can be accommodated in the vehicle frame with particularly low space and material consumption.
[0023] Preferably, the electrical energy storage device is a battery, in particular a high voltage battery.
[0024] In a fourth embodiment, the front stop rail is a front stop, and the rear console may be, for example, a towing console. The base frame, also referred to as a base carrier, with the front stop and rear console allows for easy assembly and positioning, at least substantially without load, and in particular allows for simultaneous tolerance compensation. For example, additional energy storage devices configured as high-voltage batteries can be easily positioned, for example, using the plug-in principle, in particular by placing carrier boxes one on top of another as described, and then snapping them together or nesting them together. For example, the stacked and nested carrier boxes can be attached, in particular via externally accessible screw holes, in particular on a final assembly line, thereby enabling modular installation of at least virtually any number of energy storage devices, in particular independently of a production line. Thus, the fourth embodiment allows for simple and cost-effective positioning and assembly of at least one or more energy storage devices, in particular in the vehicle height direction, above a vehicle frame configured as a lead frame (ladder frame).
[0025] Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and on the basis of the drawings. The features and combinations of features mentioned in the above description and those mentioned below in the description of the drawings and / or shown only in the drawings can also be used in other combinations or alone, as well as in the combinations presented in each case, without departing from the scope of the invention. [Brief explanation of the drawings]

[Figure 6] 1 is a schematic perspective view of the base frame of the carrier, also called the base carrier; [Figure 7] 1 is a schematic perspective view of a carrier box of a carrier configured as a carrier frame; [Figure 8] FIG. [Figure 9] FIG. 1 is a schematic partial perspective view of two carrier boxes stacked on top of each other and nested relative to each other like beverage crates. DETAILED DESCRIPTION OF THE INVENTION
[0027] In the drawings, the same elements or elements with the same functions are provided with the same reference numerals.
[0028] FIG. 1 shows a schematic perspective front view of a carrier 10, also called a loading device or configured as a loading device, for a commercial vehicle, also called simply a vehicle. This means that the commercial vehicle has the carrier 10 in a fully manufactured state. In addition, the commercial vehicle has a frame 12, also called a vehicle frame, configured as a lead frame, which is partially visible in FIG. 1. The frame 12 (vehicle frame) has two longitudinal carriers 14, 16 that are spaced apart in the transverse direction of the commercial vehicle and whose respective longitudinal extensions extend in the longitudinal direction of the commercial vehicle. The transverse direction of the commercial vehicle is specifically indicated by a double arrow 18 in FIG. 1, and the longitudinal direction of the commercial vehicle is specifically indicated by a double arrow 20 in FIG. 1. The carrier 10 is at least indirectly, in particular directly, fastened to the frame 12, in particular by the carrier 10 being at least indirectly, in particular directly, fastened to the longitudinal carriers 14 and 16. For example, the frame 12 has at least one transverse carrier, not shown in FIG. 1, through which the longitudinal carriers 14 and 16 are connected to each other such that the transverse carrier is connected to the longitudinal carriers 14 and 16, particularly at both ends.
[0029] The carrier 10 has accommodation areas 22 and 24, each of which is particularly directly defined by the carrier 10. A respective electrical energy storage device 26, 28 is arranged in, and thus accommodated in, the respective accommodation areas 22, 24. The respective energy storage devices 26, 28 are particularly directly fixed to the carrier 10, so that the energy storage devices 26, 28 are stored (supported) and therefore held by, the frame 12 using, and particularly via, the carrier 10. The respective electrical energy storage devices 26, 28 are preferably configured as high-voltage components. In particular, the respective energy storage devices 26, 28 are preferably configured as batteries, in particular as high-voltage batteries.
[0030] 2 to 4, it can be seen that the carrier 10, which is configured separately from the frame 12, has a base frame 30, also called a base carrier, which is arranged on the vehicle frame (frame 12) and fixed to the frame 12, in particular to the longitudinal carriers 14 and 16, and which defines a storage area 24 in the vehicle height direction of the commercial vehicle, in particular directly below. Furthermore, the carrier 10 has at least two or exactly two carrier boxes 32 and 34, which are configured separately from each other and each separately from the base frame 30, each carrier box 32, 34 also called or configured as a carrier frame. It can be seen that the storage area 24 is defined by the base frame 30 in the vehicle height direction of the commercial vehicle, in particular directly below, in the installation position of the carrier 10. The carrier 10 takes its installation position in the fully manufactured state of the commercial vehicle equipped with the carrier 10, and the installation position of the carrier 10 is shown in the drawings. The vehicle height direction of the commercial vehicle is specifically indicated by a double arrow 36.
[0031] The carrier box 34 is mounted, in particular directly, on the base frame 30 from top to bottom in the vehicle height direction, in particular at the installation position of the carrier 10, and is therefore arranged on the base frame 30. The carrier box 34 defines the storage area 24 on both sides in the vehicle transverse direction, i.e., on both the left and right sides. In addition, the carrier box 34 defines the storage area 24 on both sides in the vehicle longitudinal direction, i.e., on both the front and rear sides. It can be seen that the carrier box 32 is mounted on the carrier box 34 in the vehicle height direction, and is therefore arranged on the carrier box 34, so that the carrier box 34 is arranged between the carrier box 32 and the base frame 30 in the vehicle height direction.
[0032] 2, 3 and 4 it can be seen particularly well that the carrier box 34 is supported on the base frame 30 at the rear in the vehicle longitudinal direction (double arrow 20) via a plurality (two) of consoles 38, the consoles 38 being spaced apart from one another in the vehicle transverse direction, i.e. in the longitudinal extension direction of the base frame 30 and the respective carrier boxes 32, 34. In addition, the carrier box 34 is fixed to the base frame 30 via the consoles 38, in particular such that the carrier box 34 is fixed, in particular directly, to the base frame 30 with one and / or more consoles 38.
[0033] 3 and 4, it can be seen particularly well that the console 38 is configured to be folded backward in the longitudinal direction of the vehicle when subjected to an accident-related force acting from front to rear in the longitudinal direction of the vehicle and specifically indicated by arrow 40 in FIG. 3, thereby facilitating and thus enabling a movement of the carrier box 34 backward in the longitudinal direction of the vehicle, particularly configured as a pivoting movement, specifically indicated by arrow 42 in FIG. 4.
[0034] In FIG. 3 , the obstacle is designated by the reference numeral 44. For example, in the event of a head-on collision, the commercial vehicle collides head-on with the obstacle 44, resulting in the application of an accident-related force, specifically indicated by the arrow 40. From FIG. 3 , it can also be seen that the commercial vehicle, for example, in its fully manufactured state, has a structure in the form of a cab 46, which is constructed separately from the carrier 10 and from the frame 12 and is housed (supported) by the frame 12. The cab 46 is also referred to as a cabin. Due to a head-on collision, i.e., due to the application of an accident-related force resulting from a head-on collision, for example, the cab 46 is displaced rearward in the longitudinal direction of the vehicle, particularly relative to the frame 12; this accident-related rearward displacement of the cab 46 is specifically indicated in FIG. 3 by the arrow 48. In addition, from FIG. 3 , it can be seen that the carrier 10 is adjacent to the cab 46 rearward in the longitudinal direction of the vehicle (double arrow 20). Here, for example, in order to avoid an excessively strong collision between the cab 46 and the carrier 10, and therefore excessive load on the cab 46 and thus excessive deformation of the cab 46 when an accident-related force is applied, the console 38 is folded, particularly so as to move away rearward in the longitudinal direction of the vehicle relative to the frame 12, when an accident-related force is applied. As a result, when an accident-related force is applied, the carrier box 34, particularly the tower 50 formed by the carrier box 34 and the carrier box 32 arranged on the carrier box 34, is folded, particularly so as to move away rearward in the longitudinal direction of the vehicle, and / or the carrier box 34 or the tower 50 is displaced rearward in the longitudinal direction of the vehicle when an accident-related force is applied. In other words, the movement of the carrier box 34 or the tower 50 may occur rearward and away from the cab 46 in the longitudinal direction of the vehicle, thereby achieving a particularly high level of safety.
[0035] 1 and 4, it can be seen that the carrier box 34 is preferably supported on a fixed front stop rail 52, which is provided on the base frame 30 in the longitudinal direction of the vehicle, in particular forward in the installation position of the carrier 10, for example the carrier box 34 being arranged between the front stop rail 52 and the rear console 38 in the longitudinal direction of the vehicle.
[0036] In the illustrated embodiment, the aforementioned longitudinal extension direction of the base frame 30 and each carrier box 32, 34 extends in the transverse direction of the vehicle. In this case, each carrier box 32, 34 has side elements 54, 56 spaced apart from each other in the longitudinal direction of the respective carrier box 32, 34, and therefore in the transverse direction of the vehicle, by which the respective storage areas 22, 24 are defined, in particular directly, on both sides in the transverse direction of the vehicle. Furthermore, each carrier box 32, 34 has a respective front strut 58, by which the respective storage areas 22, 24 are defined, in particular directly, toward the front in the longitudinal direction of the vehicle. Furthermore, each carrier box 32, 34 has a respective rear strut 60, by which the respective storage areas 22, 24 are defined, in particular directly, toward the rear in the longitudinal direction of the vehicle. In this case, each strut 58, 60 extends obliquely to the transverse direction and obliquely to the vehicle height direction, and also extends in a plane extending in the transverse and height directions. This makes it possible to achieve a particularly high stiffness of each carrier box 32, 34 in a particularly weight-efficient manner. Furthermore, each side element 54, 56 has crisscrossing strut elements 62 that extend in an X-shape, thus forming an X-shape. This allows each strut element 62 of each side element 54, 56 to define a plurality of triangular through-openings 64 in each side element 54, 56 of each carrier box 32, 34.
[0037] In particular, the base frame 30 and the carrier boxes 32 and 34 form a kit system, by means of which various structural variants of the carrier 10 or tower 50 can be produced in a particularly simple and cost-effective manner. The base frame 30 is a base frame that can be used for the structural variants, for example, not only for the first structural variant but also for the second structural variant. The carrier boxes 32 and 34 are carrier frames that can be optionally connected to one another and to the base frame 30 and that can be arranged one on top of the other in the vehicle height direction, in particular like drinking water crates. In the first structural variant, for example, by using the base frame 30 and the carrier box 34 instead of the carrier box 32, for example, exactly one electrical energy storage device is stored in the frame 12 in the form of the electrical energy storage device 28. In the second structural variant, for example, by using the base frame 30 and the carrier boxes 32 and 34 as shown in Figures 1 and 2, for example, exactly two electrical energy storage devices 26 and 28 are stored in the frame 12. In that case, carrier box 32 is inserted onto carrier box 34, so that carrier boxes 32 and 34 are stacked on top of each other like beverage crates and can fit relative to each other. This allows carrier boxes 32 and 34 to be easily placed on top of each other and thereby positioned relative to each other. For example, carrier boxes 32 and 34 are removably connected together in a non-destructive manner, in particular by a threaded connection.
[0038] Preferably, the carrier box 34 is directly supported, in particular, by a front stop rail 52 provided on the base frame 30, and is thereby positioned relative to the base frame 30. Furthermore, the carrier box 34 is fixed to the base frame 30 via a rear console 38 provided on the base frame 30. In addition to that, for example, the carrier box 34 is fixed to the base frame 30 via the stop rail 52. In particular, the carrier boxes 32 and 34 are configured to have the same structure.
[0039] It can be seen particularly well from FIG. 5 that the struts 58, 60 allow for the realization of particularly advantageous force paths in a particularly space-saving manner.
[0040] FIG. 6 shows a schematic perspective view of the base frame 30. FIG. 7 shows a schematic perspective view of the carrier box 32. FIG. 8 shows a schematic perspective view of the carrier 10 with the base frame 30 and the carrier box 32, where the carrier box 32 is mounted on the base frame 30, in particular directly, instead of the carrier box 34. Finally, FIG. 9 shows the carrier boxes 32 and 34 stacked directly on top of each other and fitted into each other, like beverage crates or cases. As can be seen from FIGS. 1 and 9, in order to modularly manufacture or build the carrier 10, the carrier box 32 can optionally be mounted on the carrier box 34 or the carrier box 34 can be mounted on the carrier box 32, in particular interleaved.
