Description

Technical Field

[0001] The present invention relates to a protective plate arrangement structure in the bottom region of an electrically driven special protective vehicle (Sonderschutzkraftwagen) according to claim 1. Background Technology

[0002] Protective plates for special protective vehicles are well known in general existing technology. Here, the electrical accumulators arranged in the bottom area of ​​the special protective vehicle can be protected from blast shocks, bombardments and / or similar events by means of the protective plate. Summary of the Invention

[0003] The objective of this invention is to provide an arrangement structure for a protective plate in the bottom region of an electrically driven special protective vehicle, thereby significantly improving the safety of the electric energy storage device from damage and deformation and keeping the manufacturing cost of the special protective vehicle particularly low.

[0004] According to the invention, the task is accomplished by an arrangement of protective plates in the underside region of an electrically driven special protective vehicle, having the features of claim 1. Advantageous embodiments of the invention are the subject of the dependent claims and the description.

[0005] This invention relates to an arrangement structure of a protective plate in the underside region of an electrically driven special protective vehicle. The special protective vehicle is, for example, a passenger car.

[0006] Special-protection motor vehicles can be understood in particular as a type of special-protection vehicle. Special-protection motor vehicles preferably have at least one integrated armor plating to protect the occupants or cargo carried by the vehicle from external attacks. Therefore, special-protection vehicles can also be referred to as security vehicles. Preferably, the protective plating has, in particular, integrated armor. Thus, the integrated armor of a special-protection motor vehicle is, for example, at least partially constituted by the protective plating. Special-protection motor vehicles may have additional protective elements, in particular armor elements, constructed separately from the protective plating. Therefore, special-protection motor vehicles can also be referred to as armored motor vehicles.

[0007] Special protective vehicles are electrically driven, which can be understood in particular as special protective vehicles having at least one motor, by means of which the special protective vehicle can be electrically, for example, purely electrically driven. Therefore, special protective vehicles are, for example, battery electric vehicles or hybrid vehicles. In other words, special protective vehicles are constructed, for example, as battery electric vehicles or hybrid vehicles. In particular, when a special protective vehicle is constructed as a battery electric vehicle, it can be particularly understood as a purely electric vehicle.

[0008] The bottom region of a special protective vehicle can be specifically referred to as the underfloor region. Regarding the vehicle height direction of the special protective vehicle, the bottom region can be specifically understood as the lower region of the special protective vehicle, especially the lower sub-region. The bottom region, or sub-region, is arranged, for example, below the floor elements of the vehicle body, such as the main floor, in the vehicle height direction. The vehicle body is preferably constructed as a self-supporting body. Preferably, the vehicle body at least partially, especially mainly or completely, for example, at least indirectly or directly defines the interior space of the special protective vehicle. The interior space, especially what can be referred to as the vehicle interior space, can be specifically understood as the passenger space or passenger compartment.

[0009] At least one electric accumulator, located in the bottom region and particularly at least indirectly or directly attached to the body of a specially protected motor vehicle, especially to body components, is at least protected or can be protected from blast impact by a protective plate. This electric accumulator is at least partially, particularly mainly, or completely, for example, at least indirectly or directly covered by the protective plate downwards in the vehicle height direction. In other words, the electric accumulator is at least indirectly or directly fixed to the vehicle body, especially to body components, wherein the protective plate is at least partially, particularly mainly, or completely arranged below the electric accumulator in the vehicle height direction. This means that the protective plate extends at least partially, particularly mainly, or completely below the electric accumulator in the vehicle height direction. Preferably, the electric accumulator is arranged below the floor plate element in the vehicle height direction. In other words, the electric accumulator is configured as an underfloor accumulator, especially an underfloor battery. For example, an electric energy storage device, especially at least one energy storage device housing and / or at least one supporting structure of the electric energy storage device, has at least one connection area, through which the electric energy storage device is held or fixed at least indirectly, especially directly, to the vehicle body, especially the body component, particularly in the bottom area.

[0010] The accumulator is protected from explosive shocks by means of a protective plate, which can be understood in particular as a protective plate constructed or arranged to protect the accumulator located behind it, especially above it in the vehicle's height direction. An explosive shock can be understood in particular as an explosion or blast caused by explosives, such as a grenade. Therefore, the underside of a specially protected vehicle, especially the accumulator, can be protected by a protective plate from grenades detonating in the area of ​​the specially protected vehicle, especially below it in the vehicle's height direction.

[0011] Preferably, the motor can be supplied with electrical energy, particularly stored or chemically bonded in the energy storage device, via an electric energy storage device, so as to electrically, especially purely electrically, drive the special-protection vehicle. In other words, the energy storage device is preferably configured as an electric traction storage device, especially a traction battery. The energy storage device is, for example, configured as a battery or accumulator.

[0012] For example, an electric energy storage device has at least one receiving space, which is at least partially, especially mainly or completely, e.g., directly defined by or constituted by the energy storage device's housing. Preferably, multiple (especially electrical) energy storage elements are arranged or received inside the energy storage device housing or in the receiving space. In other words, the receiving space is configured to receive energy storage elements. The energy storage elements are preferably configured as individual energy storage units. Preferably, the electric energy storage device has multiple modules, especially individual unit modules, each module having multiple energy storage elements, especially individual energy storage units. The individual unit modules are preferably arranged in the receiving space or inside the energy storage device housing.

[0013] To achieve exceptionally high electrical power for use in electrically powered, especially purely electrically powered, special-purpose protective vehicles, the energy storage device can have a voltage preferably greater than 50 volts, especially exceeding 60 volts, and preferably several hundred volts, particularly the electrical operating voltage or rated voltage. Accordingly, the energy storage device is preferably constructed as a high-voltage component. In other words, the energy storage device is constructed as a high-voltage memory, especially a high-voltage battery.

[0014] To significantly improve the safety of the electric accumulator from damage and deformation and to keep the manufacturing cost of specially protected vehicles particularly low, it is stipulated that the protective plate is held, at least indirectly or directly, on the vehicle body, especially on the body components, preferably in the bottom region, relative to the vehicle body (especially body components) and the electric accumulator (especially the accumulator housing and / or load-bearing structure). This means that the protective plate is not held or fixed to the electric accumulator, especially the accumulator housing and / or load-bearing structure, and especially not held or fixed to the vehicle body via the electric accumulator, especially via the accumulator housing and / or load-bearing structure. In other words, the protective plate is decoupled from the accumulator housing fixing structure, and the electric accumulator, especially the accumulator housing and / or load-bearing structure, is held in the bottom region, especially on the vehicle body, especially at least indirectly or directly, via the accumulator housing fixing structure. In yet another word, the protective plate is held or fixed to the vehicle body independently of the electric accumulator.

[0015] For example, the protective plate has at least one fixing region, through which it is held or fixed to the vehicle body, particularly the body components, at least indirectly or directly, especially relative to the electric accumulator and the vehicle body. In particular, the protective plate is held to the vehicle body, particularly the body components, in a bottom region via the fixing region in a manner decoupled from the accumulator housing fixing structure. Therefore, the fixing structure of the electric accumulator, particularly via the connecting region, on the vehicle body is decoupled from the fixing structure of the protective plate, particularly via the fixing region, on the vehicle body. This means that the fixing structure of the protective plate, particularly via the fixing region, on the vehicle body, particularly on the body components, extends around the electric accumulator, particularly around the accumulator housing and / or the load-bearing structure.

[0016] This invention is based, in particular, on the understanding and consideration that, in order to achieve the desired protective effect for electric accumulators, the protective plate, especially the so-called bottom protective plate, typically has a particularly high thickness, which is accompanied by a high weight. This weight can be considered an additional weight that should be placed in a special protective vehicle. In principle, it is conceivable that the protective plate is directly fixed to the electric accumulator, especially to the accumulator housing and / or the load-bearing structure, via a fixing area. Due to the particularly high weight of the protective plate, the connection structure of the accumulator housing and / or the load-bearing structure and / or the electric accumulator on the vehicle body, for example by means of a threaded connection, may therefore have to be sized particularly large or particularly strong. This results in the inability to use mass-produced electric accumulators, especially the accumulator housing and / or the load-bearing structure and / or the connection structure of mass-produced electric accumulators, in special protective vehicles. Therefore, compared to unarmored vehicles, i.e., other vehicles not constructed as special-protection vehicles, the electric accumulators and / or the connection structures of the electric accumulators on the body of special-protection vehicles must be individually adjusted to accommodate these components. In other words, the added weight of the protective plate may be too high, making it impossible to connect the plate directly to the electric accumulator itself, especially if adjustments to the design of mass-produced connection structures, particularly mass-produced threaded connections, are not necessary. This will adversely affect the manufacturing costs of special-protection vehicles.

[0017] In contrast, the protective plate can be fixed to the vehicle body in a manner decoupled from the energy storage device, without being fixed to or via the energy storage device, thanks to the arrangement structure of the present invention. Therefore, for example, a direct connection between the protective plate and the vehicle body, especially with body components, can be achieved, wherein the connection structure does not extend via the energy storage device, especially not via the load-bearing structure and / or the energy storage device housing. Thus, the energy storage device, especially the load-bearing structure and / or the energy storage device housing and / or the connection structure between the energy storage device and the vehicle body, particularly across structural variations, can be applied across structural variations in both specially protected vehicles and unarmored vehicles. This means that the number of common components in specially protected vehicles and other vehicles can be significantly increased. Consequently, the manufacturing cost, especially the manufacturing expense, of specially protected vehicles can be kept particularly low. Overall, it can be seen that it is possible to integrate underbody armor, in the form of a protective plate for the energy storage device, into the vehicle body and connect it to the vehicle body in a manner decoupled from the energy storage device.

[0018] In another design, the protective plate is specified to be held, in particular, via a fixed area, at least indirectly or directly, on at least one side sill of the special-protection vehicle. In other words, the protective plate is held only on the side sill, and particularly via the side sill, relative to the at least one side sill and the electric accumulator. Thus, the protective plate can be secured to the vehicle body with particularly low cost and / or particularly reliable, and particularly strong mechanical load-bearing capacity. The side sill can be part of the vehicle body, or it can be constructed separately from the vehicle body. Therefore, a body component, for example, is the side sill.

[0019] For example, the energy storage device is held on the at least one side sill, particularly via a connection area, at least indirectly or directly. The connection area is, for example, part of the energy storage device housing and / or the supporting structure.

[0020] Another design scheme specifies that the protective plate and the side sill are spaced apart from each other in the vehicle height direction of the special protective vehicle. This means that a gap extending in the vehicle height direction is provided between the protective plate and the side sill, specifically preventing direct contact between the protective plate and the side sill.

[0021] Preferably, the protective plate is held on the side sill by means of at least one intermediate element arranged between the side sill and the protective plate in the vehicle height direction, particularly at least indirectly or directly. In other words, the protective plate is held or fixed to the side sill via the intermediate element, wherein the intermediate element extends at least partially, particularly mainly or completely, between the protective plate and the side sill. This means that the intermediate element is arranged below the side sill and above the protective plate in the vehicle height direction. The gap between the protective plate and the side sill can be bridged by the intermediate element, particularly avoiding, for example, direct coupling between the protective plate and the electric accumulator. Thus, the protective plate can be fixed to the vehicle body, particularly to the side sill, with particularly low cost and / or particularly reliable connection in relation to the electric accumulator. In particular, the protective plate is supported upward in the vehicle height direction via the intermediate element or can be supported on the side sill.

[0022] For example, it is specified that the intermediate element is constructed as a spacer sleeve. In other words, the intermediate element is constructed in a sleeve shape. The intermediate element being constructed in a sleeve shape, that is, constructed as a sleeve, can be understood in particular as the intermediate element being constructed as a hollow cylinder. As a result, the protection plate can be fixed to the vehicle body with particularly low cost, and especially independently of the electric accumulator.

[0023] In another design, at least one receiving element is specified, in particular, directly arranged on the side sill. In other words, at least one receiving element is provided or constructed on the side sill. The receiving element and the side sill can be constructed separately from each other, and in particular, directly connected to each other. Alternatively, the side sill and the receiving element can be constructed as a single piece. The receiving element is constructed, for example, as a threaded sleeve. Therefore, the receiving element, for example, has at least one internal thread.

[0024] Preferably, at least one threaded element, particularly directly disposed on the protective plate and guided through the intermediate element, is screwed directly onto the receiving element in order to hold the protective plate, at least indirectly or directly, on the side sill by means of at least one threaded connection structure. In other words, the protective plate and the side sill are screwed together by means of the receiving element and, particularly, by means of the intermediate element. Thus, the protective plate can be disposed on the side sill with particularly low cost and / or particularly reliable. In particular, the protective plate is held on the side sill by means of a threaded connection structure.

[0025] The threaded connection structure can be understood in particular as a threaded connection structure consisting of a protective plate, a threaded element, a receiving element, and a side sill, and especially an intermediate element. The threaded element preferably has at least one external thread, via which it is screwed onto the internal thread of the receiving element. The threaded element is guided through the intermediate element, which can be understood as the intermediate element having at least one through opening, in which the threaded element is partially disposed. The through opening can be understood in particular as a cavity of the intermediate element. In particular, the threaded element extends partially within the through opening or inside the cavity. This means that the threaded element is inserted through the intermediate element, especially the through opening.

[0026] In another design, the electric accumulator, particularly the accumulator housing and / or supporting structure, has at least one profile, particularly an extruded profile, via which the electric accumulator is held, at least indirectly or directly, to the vehicle body, particularly to the side sill. In other words, the electric accumulator is fixed to the vehicle body, particularly to the side sill, via the profile. This allows the electric accumulator to be fixed to the vehicle body with particularly low cost and / or particularly reliable stability. Furthermore, in the event of an accident involving a special-protection vehicle, particularly a side collision, the extruded profile can act as a deformable element to reduce collision energy. This, in particular, can significantly improve the passive safety of the special-protection vehicle in a particularly weight-advantageous and / or particularly low-cost manner. Specifically, the connection area of ​​the electric accumulator is at least partially, particularly mainly or entirely, formed by the profile. This means that the extruded profile can have a connection area. Preferably, the profile extends at least partially below the side sill in the vehicle height direction. This means that the profile is at least partially arranged below the side sill in the vehicle height direction. The extruded profile is preferably constructed as an aluminum extruded profile.

[0027] In another design, the profile is specified to have at least one through-opening through which an intermediate element is guided, and in particular inserted, through the through-opening. In other words, the intermediate element is at least partially arranged inside the through-opening. Thus, the intermediate element can be guided through the profile decoupled from it, so that the protective plate can be connected to the side sill via the intermediate element in a manner decoupled from the electric accumulator, and in particular from the profile. Therefore, the manufacturing cost of the special protective vehicle can be kept particularly low. Thus, a direct connection between the protective plate and the vehicle body can be achieved by means of a spacer sleeve inserted through the electric accumulator, specifically the accumulator housing known as the high-voltage accumulator housing.

[0028] A through opening can be understood in particular as a gap or void in the profile. A void can be understood in particular as a material void. Preferably, the intermediate element is entirely defined by the profile or surrounded by the wall forming the through opening in its circumferential direction.

[0029] In other design schemes, it is specified that at least one coupling element, specifically constructed separately from the receiving element, is arranged directly on the side sill. In other words, at least one coupling element is provided or constructed on the side sill. The side sill and the coupling element can be constructed separately from each other, and in particular, are connected to each other. Alternatively, the side sill and the coupling element can be constructed together as a single piece. The coupling element is constructed, for example, as a threaded sleeve. Preferably, the coupling element has at least one internal thread.

[0030] Preferably, the threaded elements, particularly those directly disposed on the profile, are tightened with coupling elements to hold the energy storage device, at least indirectly or directly, on the side sill via the profile using at least one threaded connection structure. This threaded connection structure may be referred to as a second threaded connection structure. In other words, the extruded profile and the side sill are tightened together via coupling elements, i.e., connected to each other by means of the at least one second threaded connection structure. Thus, the energy storage device can be connected to the side sill with particularly low cost and / or particularly reliable connection. In particular, the energy storage device is held on the side sill via the profile using the second threaded connection structure.

[0031] The second threaded connection structure can be understood in particular as a threaded connection structure consisting of a profile, a coupling element, and a side sill. The threaded element preferably has at least one external thread, which is tightened with the internal thread of the coupling element.

[0032] To particularly enhance the safety of the electric accumulator from damage and deformation, it is stipulated that at least all accumulator elements, especially the receiving space, are at least indirectly or directly covered or can be covered by a protective plate in the vehicle height direction, specifically to protect the electric accumulator, preferably individual accumulator units or the receiving space, from explosive impact. In other words, the protective plate arranged below the electric accumulator in the vehicle height direction extends below all accumulator elements, especially below the receiving space, in both the vehicle longitudinal and transverse directions.

[0033] For example, it is specified that the receiving space, especially the electric energy storage unit, is covered or can be covered downwards, particularly directly, in the vehicle height direction along its entire length extending in the longitudinal direction of the vehicle and along its entire width extending in the lateral direction of the vehicle. In other words, the protective plate extends at least along the entire bottom surface of the receiving space, especially the electric energy storage unit, such as the energy storage unit housing, in both the longitudinal and lateral directions of the vehicle, wherein the protective plate is arranged below the electric energy storage unit in the vehicle height direction. This means that the protective plate extends at least along the entire length of the receiving space, especially the electric energy storage unit, extending in the longitudinal direction of the vehicle, and at least along the entire width of the receiving space, especially the electric energy storage unit, extending in the lateral direction of the vehicle, below the electric energy storage unit in the vehicle height direction. Therefore, the length of the protective plate extending in the longitudinal direction of the vehicle is at least as long as the length of the receiving space, especially the electric energy storage unit, extending in the longitudinal direction of the vehicle, and the width of the protective plate extending in the lateral direction of the vehicle is at least as wide as the width of the receiving space, especially the electric energy storage unit, extending in the lateral direction of the vehicle. Because the electric storage device is positioned downwards in the vehicle height direction, and is especially completely covered by or with the aid of a protective plate, it can be fully protected from explosive impacts in the bottom area (especially high-voltage memory protection).

[0034] The length of the receiving space or electric energy storage unit extending longitudinally in the vehicle can be understood as the total length of the receiving space or electric energy storage unit. The width of the receiving space or electric energy storage unit extending laterally in the vehicle can be understood as the total width of the receiving space or electric energy storage unit.

[0035] For example, an electric accumulator is protected or can be protected from bombardment by a protective plate. This means that the electric accumulator is protected or can be protected from explosive shocks and bombardment and / or similar situations by a protective plate. In particular, bombardment can be understood as bombardment of a specially protected vehicle, especially its undercarriage area, by a gun or projectile.

[0036] In other design schemes, it is specified that the protective plate is made entirely of aluminum, particularly aluminum alloy. This means that the material of the protective plate, specifically referred to as the material, is aluminum or an aluminum alloy. In other words, the protective plate is constructed as an aluminum plate. This allows for a particularly advantageous increase in the mechanical load-bearing capacity of the protective plate in a weight-saving manner. Therefore, it is possible to significantly improve the safety of the energy storage device from damage and deformation, while simultaneously keeping the weight of the protective plate, especially for special protective vehicles, particularly low. The use of an aluminum protective plate allows for control of dynamic bulging and / or plastic deformation of the protective plate due to or during an explosive impact, preventing damage to the energy storage device, especially the charged energy storage cells. The protective plate can, particularly as required, be made of other materials and / or composite materials. Alternatively or additionally, the protective plate can be constructed in a sandwich structure.

[0037] In another design, the protective plate is spaced apart from the accumulator, and especially from the accumulator housing, in the vehicle height direction. This avoids, with particularly low cost, undesirable contact between the protective plate and the accumulator, and especially the accumulator housing, allowing the accumulator housing to be used across structural variations for both specially protected vehicles and unarmored vehicles. Furthermore, it prevents the protective plate from exerting loads on the accumulator in the event of deformation, thereby significantly improving the accumulator's safety from damage and deformation.

[0038] For example, it is stipulated that the width of the electric accumulator, especially the accumulator housing, particularly extending in the lateral direction of the vehicle, is at least 50%, especially at least 60%, 70%, 80%, 90%, or 95% of the total width of the special-protection vehicle extending in the lateral direction of the vehicle. In other words, at least 50%, especially 60%, 70%, 80%, 90%, or 95% of the bottom area, especially the bottom, is covered downwards by or can be covered by a protective plate in the vehicle height direction. This allows the use of particularly large electric accumulators, thereby significantly increasing the electric, especially purely electric, range of the special-protection vehicle. At the same time, the electric accumulator can be particularly well protected from blast impacts. For example, the width of the electric accumulator corresponds to the total width of the special-protection vehicle. In other words, the protective plate extends in the lateral direction of the vehicle, particularly the bottom area, in the total width extending in the lateral direction of the vehicle.

[0039] In another design, the protective panel is specified as a single piece. This means that the protective panel consists of one piece, such as a single block. Therefore, the protective panel does not have components that are constructed separately and, in particular, subsequently connected to each other after the respective manufacturing process. In other words, the protective panel is not a composite panel, meaning that it does not have a layered structure with multiple layers. As a result, the manufacturing cost of the protective panel can be kept particularly low.

[0040] Other features of the invention are derived from the claims, the drawings, and the description of the drawings. The features and combinations of features mentioned in the description above, and the features and combinations of features mentioned and / or shown only in the drawings below, can be used not only in the corresponding combinations given, but also in other combinations or independently.

[0048] Figure 7 A schematic top view of the arrangement structure according to the present invention is shown. Detailed Implementation

[0049] In the accompanying drawings, the same or functionally identical elements are given the same reference numerals.

[0050] Figure 1 The arrangement structure 1 of the protective plate 2 in the bottom region 3 of the electrically driven special protective vehicle 4 is shown obliquely from below in a schematic perspective view. In particular, in Figure 1 The diagram shows a schematic, perspective partial view of the special protective vehicle 4. Figure 2 The arrangement structure 1, especially the special protective vehicle 4, is shown in a schematic and perspective partial sectional view.

[0051] The special protective vehicle 4 has, in particular, a self-supporting body 5, which preferably at least partially, in particular mainly, or completely defines or constitutes the interior space 6 of the special protective vehicle 4. In the embodiment, the body 5 has at least one floor element 7, which is configured, for example, as the main floor of the body 5. The floor element 7 at least partially, in particular mainly, or completely defines the interior space 6 downward in the vehicle height direction 8 of the special protective vehicle 4. The body 5 preferably has two side walls 9. This means that the body 5 has a first side wall 9 and a second side wall spaced apart from the first side wall 9 in the vehicle lateral direction 10. The corresponding side wall can in particular be referred to as a corresponding side frame. Preferably, the corresponding side wall 9 at least partially, in particular mainly, or completely defines the interior space 6 in the vehicle lateral direction 10.

[0052] In the embodiment described, the vehicle body 5 has two side sills 11. This means that the vehicle body 5 has a first side sill 11 and a second side sill spaced apart from the first side sill 11 in the vehicle lateral direction 10. For example, the respective side sill 11 is connected downwards at least indirectly, and in particular directly, to the respective side wall 9 in the vehicle height direction 8, and in particular to the respective outer component 12 of the respective side wall 9. The respective side sill 11 may be part of the respective side wall 9 or the respective side sill 11 may be constructed separately from the respective side wall 9.

[0053] For example, the corresponding sidewall 9 has at least one internal component 13, constructed separately from the corresponding external component 12, by means of which the special protective vehicle 4, especially the interior space 6, is preferably protected from explosive impacts, bombardments, and / or similar situations. Therefore, the internal component 13 is, for example, made of armor steel.

[0054] Figure 3 The arrangement structure 1 is shown in a schematic partial cross-sectional view. The special protective vehicle 4 has at least one electric accumulator 14, which is arranged in the bottom region 3, particularly below the floor element 7 in the vehicle height direction 8. The electric accumulator 14 has at least one accumulator housing 15. The electric accumulator 14, and especially the accumulator housing 15, is held on the vehicle body 5, for example, via at least one connection region 16 (particularly at least indirectly or directly). The connection region 16 can be understood in particular as the fixing region of the electric accumulator 14, and especially the accumulator housing 15. In the embodiment, the electric accumulator 14, and especially the accumulator housing 15, is screwed to the vehicle body 5, for example, via the connection region 16.

[0055] The electric accumulator 14 is at least partially, especially mainly or completely, covered downwards by the protective plate 2 in the vehicle height direction 8. Thus, the electric accumulator 14 is at least protected or can be protected from the impact of an explosion by means of the protective plate 2.

[0056] For example, the protective plate 2 is held on the vehicle body 5 at least indirectly, and especially directly, via at least one fixed area 17 of the protective plate 2.

[0057] To particularly enhance the safety of the electric accumulator 14 from damage and deformation, and to keep the manufacturing cost of the special-protection vehicle 4 particularly low, it is stipulated that the protective plate 2 is held on the vehicle body 5 (especially the corresponding side sill 11) and the electric accumulator 14 (e.g., via the fixing area 17). This means that the protective plate 2 and the electric accumulator 14 are fixed to the vehicle body 5 independently of each other via the connection area 16 and the fixing area 17, respectively. Thus, for example, only the electric accumulator 14 is held on the vehicle body 5 with respect to the electric accumulator 14 and the protective plate 2 via the connection area 16, and the protective plate 2 is held on the vehicle body 5 with respect to the protective plate 2 and the electric accumulator 14 via the fixing area 17. Therefore, the connection structure or fixing structure of the protective plate 2 on the vehicle body 5 can be decoupled from the electric accumulator 14. Thus, at least one connection structure of the electric accumulator 14 can be used across structural variations for special-protection vehicles and for other unarmored vehicles.

[0058] In the embodiment, the protective plate 2 extends at least in the lateral direction 10 of the vehicle to the side sill 11 of the special protective vehicle 4.

[0059] In another design, the protective plate 2 is specified to be held on at least one of the side sills 11. In this embodiment, the protective plate 2 is held on each side sill 11, that is, fixed to each side sill 11 on both sides with respect to the lateral direction of the vehicle. This means that the protective plate is held on the vehicle body 5 only via the respective side sill 11 relative to the corresponding side sill 11 and the electric accumulator 14.

[0060] In the embodiment described, the electric accumulator 14 is held on the side sill 11, particularly via its accumulator housing 15. This means that the electric accumulator 14 is held on the vehicle body 5 via the side sill 11.

[0061] In another design, the protective plate 2 and the corresponding side sill 11 are spaced apart from each other in the vehicle height direction 8, and the protective plate 2 is held on the corresponding side sill 11 by means of at least one intermediate element 18 arranged in the vehicle height direction 8 between the corresponding side sill 11 and the protective plate 2.

[0062] Figure 4 The arrangement structure 1 is shown in a schematic and perspective partial sectional view. Here, in Figure 4 As can be seen, a plurality of intermediate elements 18 are provided, particularly those associated with the corresponding side sills 11, and the protective plate 2 is held on the corresponding side sills 11 by means of the intermediate elements. The intermediate elements 18 are arranged between the corresponding side sills 11 and the protective plate 2 in the vehicle height direction 8. Preferably, the corresponding intermediate elements 18 are constructed as corresponding spacer sleeves 19.

[0063] In another design, at least one receiving element 20 is arranged, and in particular held, on the respective side sill 11. For example, the respective receiving element 20 is arranged at least partially, and in particular mainly or completely, above the sill base plate 11a of the respective side sill 11 in the vehicle height direction 8. In this embodiment, multiple receiving elements 20, for example configured as threaded sleeves, are arranged, and in particular held, on the respective side sill 11. Threaded elements 21 arranged on the protective plate 2 and guided through the respective intermediate elements 18 are screwed onto the respective receiving elements 20 to hold the protective plate 2 on the side sill 11, in particular on the respective sill member 24 of the respective side sill 11 and / or on the sill base plate 11a, by means of a respective threaded connection structure 22. For example, the respective receiving element 20 is arranged (in particular directly) on, and in particular held on, the respective sill member 24 of the respective side sill 11 and / or on the respective sill base plate 11a. The respective sill member 24 is, for example, arranged inside the respective side sill 11. This means that the corresponding side sill 11 has, for example, at least one cavity in which the corresponding sill components 24 are respectively arranged.

[0064] Therefore, it can be stipulated that the protective plate 2 is not (especially directly) connected to the electric accumulator 14, especially to its accumulator housing 15, but is separately connected to the corresponding side sill 11 via a sleeve, especially a corresponding spacer sleeve and a corresponding threaded sleeve. In particular, the corresponding protective plate 2 is arranged in the vehicle height direction 8 between the corresponding screw head of the corresponding threaded element 21 and the corresponding intermediate element 18. The corresponding threaded element 21 is constructed, for example, as a corresponding screw. Figure 5 A schematic and perspective partial sectional view shows the arrangement structure 1 in the first section, in which the corresponding threaded connection structure 22 is shown. For example, the sill member 24 is directly connected to the inner member 13. Figure 3 and Figure 5 As exemplarily shown, the corresponding screw head of the corresponding threaded element 21 is, for example, at least partially, especially mainly or completely (preferably in the protective plate 2) sunk.

[0065] In another design, the energy storage device 14, and in particular the energy storage device housing 15, has at least one profile, which in this embodiment is constructed as an extruded profile 25, particularly an aluminum extruded profile. The energy storage device 14 is held on the vehicle body 5, particularly on the corresponding side sill 11, for example, on the corresponding sill member 24 of the corresponding side sill 11, via the extruded profile 25.

[0066] As in Figure 4 and Figure 5As exemplarily shown, in the embodiment specified, the extruded profile 25 has at least one through opening 26, and in particular, multiple through openings 26. Corresponding intermediate elements of the intermediate elements 18 are guided through the respective through openings 26.

[0067] Figure 6 The arrangement structure 1 in the second section is shown in a schematic and perspective partial sectional view, which is located, for example, in the longitudinal direction 27 of the vehicle, in front of or behind the first section. In another design, at least one corresponding coupling element 28 is arranged, and in particular held, on the respective side sills 11. In the embodiment described, a plurality of coupling elements 28, for example configured as corresponding threaded sleeves, are arranged, and in particular held, on the side sills 11, particularly on the respective sill members 24 of the respective side sills 11. Second threaded elements 29, arranged (in particular directly) on the extruded profile 25, are respectively screwed directly to the corresponding coupling elements 28, so that the electric accumulator 14 is held (in particular at least indirectly or directly) on the respective side sills 11, particularly on the respective sill members 24, via the extruded profile 25 by means of at least one second threaded connection structure 30. The threaded elements 21, 29 are constructed separately from each other. The threaded connection structures 22, 30 are different from each other, and in particular constructed separately from each other.

[0068] In the embodiment, the corresponding coupling element 28 is arranged at least partially, especially mainly or completely, in the vehicle height direction 8 above the sill base plate 11a of the corresponding side sill 11.

[0069] In the described embodiment, the electric energy storage device 14 is held on the corresponding side sill 11, particularly on the corresponding sill base plate 11a or the corresponding sill member 24, via the extruded profile 25 by means of at least one second intermediate element 31, or in particular multiple second intermediate elements 31. The corresponding second intermediate element 31 is, for example, annular, that is, constructed as a corresponding intermediate ring or a corresponding intermediate disc. In the described embodiment, corresponding threaded elements 29 are respectively guided through the corresponding second intermediate elements 31. Current isolation between the extruded profile 25 and the corresponding side sill 11 can be achieved, for example, by means of the corresponding second intermediate elements 31.

[0070] As in Figure 4As shown, for example, it is specified that at least one or more second threaded connection structures of the second threaded connection structures 30 are respectively arranged between two corresponding first threaded connection structures in the first threaded connection structure 22 in the longitudinal direction 27 of the vehicle. This means that at least one or more corresponding coupling elements of the coupling elements 28 are respectively arranged between two corresponding receiving elements in the receiving element 20 in the longitudinal direction 27 of the vehicle. Therefore, the threaded connection structures 22, 30 are arranged staggered from each other, for example, in the longitudinal direction 27 of the vehicle.

[0071] In the embodiment described above, the protective plate 2 is made of aluminum 32.

[0072] As in Figure 5 and Figure 6 As shown, for example, it is specified that: the accumulator housing 15 has an extruded profile 25 as a first housing component 33, and has at least one second housing component 34 constructed, particularly separately from the first housing component 33, the second housing component being constructed, for example, as a cover. The housing components 33, 34 are, for example, screwed together. For example, the receiving space 14a for receiving the accumulator element 14b of the electric accumulator 14 is defined or formed by the first housing component 33 at least in the vehicle transverse direction 10. Alternatively or additionally, the receiving space 14a is defined or formed, for example, by the second housing component 34 in the vehicle height direction 8, particularly upward and / or in the vehicle transverse direction 10, particularly outward.

[0073] For example, a plurality of lateral elements 35, particularly constructed as beams, are provided, extending between side sills 11 in the vehicle's lateral direction 10, wherein the side sills 11 are supported to each other in the vehicle's lateral direction 10, for example, via the lateral elements 35 (particularly at least indirectly or directly). In the embodiment described, the lateral elements 35 are spaced apart from each other. For example, the energy storage unit 14 has a plurality of modules, wherein at least one corresponding module is arranged between the lateral elements 35. Thus, the modules are separated from each other, for example, by means of the lateral elements 35. The corresponding modules can be understood, in particular, as corresponding individual modules. For example, each corresponding module has a plurality of energy storage elements 14b of the energy storage unit 14.

[0074] Figure 7A schematic top view illustrates an arrangement 1 according to another embodiment, particularly the protective plate 2 and the electric accumulator 14. Preferably, all accumulator elements 14b of the electric accumulator 14 are covered downwards by the protective plate 2 in the vehicle height direction 8. In particular, it is stipulated that at least the receiving space 14a, that is, at least the accumulator elements, are covered downwards by the protective plate 2 in the vehicle height direction 8 along the entire length 36 of the receiving space 14a extending in the vehicle longitudinal direction 27 and along the entire width 37 of the receiving space 14a extending in the vehicle lateral direction 10.
