Description

Field of the technology

[0001] The present disclosure relates to a motor vehicle having a battery disposed adjacent to an exhaust muffler on a rear floor. Background art

[0002] A motor vehicle may have a combustion machine which, among other things, includes an internal combustion engine and an exhaust system that discharges exhaust from the internal combustion engine. To reduce the sound emission from the internal combustion engine, the exhaust system generally includes at least one exhaust muffler which is disposed at the rear of a motor vehicle rear axle under the rear floor of the motor vehicle.

[0003] In known vehicle structures, among other things, a battery formed of a plurality of electrochemical cells is at least partially disposed in a battery receptacle, and is at least partially disposed between the rear axle and the exhaust muffler, and is disposed on the rear floor and formed as a tray, wherein the battery receptacle may be formed on a bottom plate of a spare wheel receptacle formed on the rear floor.

[0004] In a rear-end collision of such a motor vehicle with an object, the rear components of the motor vehicle (particularly body components or the rear floor) may undergo plastic deformation. During the collision, the physical contact between the plastically deformed component and the exhaust muffler may cause the exhaust muffler to shift forward in the direction of the battery receptacle and physically contact the battery receptacle, whereby the battery receptacle may also plastically deform. In particular, it may occur that the battery receptacle shifts forward and becomes trapped between the rear axle and the exhaust muffler, and thus plastically deform.

[0005] Due to the plastic deformation of the battery receptacle, the battery may be trapped and damaged, which must be absolutely avoided for safety reasons. Moreover, in the case of a rear-end collision, a spare wheel disposed above the battery may, for example, press the battery from above due to the displacement of the spare wheel and damage the battery. In addition, due to the high axial load on the rear axle, the rear axle may be disposed closer to the vehicle floor, which further adversely affects the component situation in the rear region and may cause the above-mentioned battery receptacle to be trapped between the rear axle and the exhaust muffler. In addition, due to the displacement of components relative to each other, contact may occur between the hot components of the exhaust system and the battery (such as a lithium-ion battery) or other highly flammable components or materials. These processes mean that the desired and / or specified safety objectives cannot be achieved. Summary of the invention

[0006] The object of the present invention is to provide a motor vehicle having a rear structure with improved safety.

[0007] According to the present disclosure, the object is achieved by a motor vehicle comprising at least one deflection element arranged between a battery receptacle and a vehicle component and configured such that a vehicle component coming into contact with the deflection element due to a lateral and / or forward displacement of the vehicle component is pressed downward in the direction of the ground by the element during a further lateral or forward displacement.

[0008] It should be noted that the features and measures listed separately in the following description can be combined with one another in any technically reasonable way, and other embodiments of the present disclosure are disclosed. This description further characterizes and specifies the present disclosure in particular in conjunction with the drawings.

[0009] A rear-end collision in the sense of the present disclosure means any impact on the rear (also including a lateral component). A forward displacement in the sense of the present disclosure means a displacement in the direction of the front of the vehicle along the longitudinal axis of the vehicle, wherein the movement stroke can also have a component oriented transversely to the longitudinal axis.

[0010] The vehicle component can be an exhaust component, in particular an exhaust muffler, and the present disclosure is not limited to an exhaust muffler. The exhaust component can also be merely a pipe portion of an exhaust component or another component, such as an exhaust aftertreatment system or another component arranged in an exhaust pipe. Optionally, the vehicle component can be a spare wheel mounted under the floor. The vehicle component can be offset partially or completely to the side and / or rear relative to the battery receptacle.

[0011] If a rear-end collision with an object (e.g., a vehicle impact from the rear) occurs in a motor vehicle according to the present disclosure, an exhaust muffler arranged at the rear relative to the battery receptacle or, correspondingly, a spare wheel can move forward in the direction of the battery receptacle. Beyond a specific displacement stroke, physical contact occurs between the forward-displaced exhaust muffler or spare wheel and the deflection element, which is arranged between the exhaust muffler or spare wheel on one side and the battery receptacle on the other side. When the exhaust muffler or spare wheel moves further forward in the longitudinal direction of the vehicle, the exhaust muffler or spare wheel is pressed downward in the direction of the ground or the road surface by the deflection element, and thus deflected from the movement path in the direction of the battery receptacle. Thus, it is reliably prevented that the exhaust muffler or spare wheel physically contacts the battery receptacle during a rear-end collision (whereby the battery receptacle may plastically deform and the battery may be damaged). Thus, it is also prevented that the battery receptacle, which may have moved forward during the collision and thus physically contacts the rear axle, becomes trapped between the rear axle and the exhaust muffler or spare wheel, thereby preventing further plastic deformation. Moreover, due to the deflection of the exhaust muffler or spare wheel during a collision event, additional vehicle parts are exposed by the deformation of the vehicle component to absorb impact energy, thereby improving the accident characteristics of the motor vehicle. Thus, a motor vehicle according to the present disclosure has a rear structure that is improved with respect to safety.

[0012] If a rear-side collision with an object (e.g., a vehicle impact from the side) occurs in a motor vehicle according to the present disclosure, the exhaust pipe can be arranged on the side (on the impact side) relative to the battery receptacle, or the exhaust muffler arranged on the side of the battery receptacle is laterally displaced in the direction of the battery receptacle. Outside a specific displacement stroke, physical contact occurs between the laterally displaced exhaust pipe or exhaust muffler and a deflection element arranged between the exhaust pipe or exhaust muffler and the battery receptacle. When the exhaust pipe or exhaust muffler moves further laterally in the vehicle transverse direction, the exhaust pipe or exhaust muffler is pressed downward by the deflection element in the direction of the ground or road surface, thereby deflecting from the movement path along the direction of the battery receptacle. Thus, physical contact between the exhaust pipe or exhaust muffler and the battery receptacle during a rear-side collision (whereby the battery receptacle may plastically deform and the battery may be damaged) can be reliably prevented. Moreover, due to the deflection of the exhaust pipe or exhaust muffler during a collision event, additional vehicle parts are exposed through the deformation of vehicle components to absorb impact energy, thereby improving the accident characteristics of the motor vehicle. Thus, the motor vehicle according to the present disclosure has a rear structure that is improved with respect to safety.

[0013] The deflection element can be made of plastic, composite material (especially fiber composite material), metal or metal alloy (especially steel). The deflection element can be made into a sheet metal part using a stamping process or a 3D printing process. In addition, the deflection element can also be integrated in a battery tray or a rear floor (made of plastic or SMC (sheet molding compound)). The deflection element can have at least one linear or curved contact surface along which vehicle components can be guided during a collision event. Preferably, the closer a part of this contact surface is arranged to the battery receptacle, the farther this part of the contact surface is from the rear floor of the motor vehicle. At the floor, the deflection element can be fixed to the rear floor of the motor vehicle. Optionally or additionally, the deflection element can be fixed to the battery receptacle on the side or at the rear. Optionally, the deflection element can be arranged at a distance from the battery receptacle on the side or at the rear. The deflection element can include angled parts and / or flanges to increase the inherent stability of the deflection element using the least amount of material. The deflection element preferably extends to the lower end of the battery receptacle on the floor side. The motor vehicle can have two, three, four or more corresponding deflection elements, which are preferably arranged at intervals from each other in the vehicle longitudinal direction or the vehicle transverse direction. On the other hand, such a deflection element can also be arranged on vehicle components, and / or vehicle components can have a special form that facilitates sliding along the deflection element, such as an integral chamfer or a circular (e.g., oval) shape added at the rear.

[0014] The motor vehicle can be, for example, a passenger car or a truck. In particular, the motor vehicle can have a conventional drive formed solely by an internal combustion engine, or a hybrid-electric drive or an all-electric drive. The rear axle of the motor vehicle can be configured, for example, as a multi-link axle. The exhaust muffler arranged at the rear relative to the battery receptacle can extend in the vehicle transverse direction. The battery can be used to supply electrical power to the vehicle electrical equipment. Optionally or additionally, the battery can be used as a traction battery. The battery preferably comprises a plurality of electrochemical cells, especially lithium-ion cells, electrically connected together.

[0015] According to an advantageous embodiment, the deflection element comprises triangular ribs which extend parallel or transverse to the vehicle longitudinal direction and taper in the direction of the ground. Here, a rib is a component which is thinner relative to the longitudinal extension of the component. Such a deflection element can be produced easily and economically due to its low physical complexity. Due to the straight or curved tapering of the ribs, an inclined contact surface is provided such that the vehicle component can slide along this inclined contact surface in the direction of the ground during a rear-end collision to deflect the vehicle component. Preferably, the ribs are formed as right-angled triangles. Here, the deflection element can be arranged such that the longest edge face of the deflection element serves as the contact surface for contacting the vehicle component. The contact surface of the rib for contacting the vehicle component can be arranged at an angle, which is optimized relative to the corresponding shape of the vehicle component and the deflection characteristics of the deflection element. The ribs can also have other forms. For example, the contact surface of a rib formed as a right-angled triangle can also be formed concave or convex and individually adapted to the geometry of the vehicle component with which it comes into contact. The ribs can also be formed as trapezoidal quadrilaterals, where the lower abdominal plate in the longitudinal direction of the rib is chosen to be significantly shorter than the upper abdominal plate to ensure the deflection function of the rib. In this way, if necessary, a greater distance from the vehicle component on the vehicle longitudinal axis can be bridged.

[0016] Another advantageous embodiment provides that a part of the deflection element in contact with the vehicle component is formed as a plane. In this way, a sharp or abrupt linear contact between the deflection element and the vehicle component is avoided, which, for example, prevents the exhaust muffler from being cut by the deflection element during a collision event and hinders the sliding of the exhaust muffler due to increased friction or catching. The planar structure of the part of the deflection element in contact with the vehicle component in a collision situation can be achieved by tilting the deflection element, thickening the deflection element or the like.

[0017] According to another advantageous embodiment, at least one surface of the vehicle component intended to come into contact with the deflection element is formed as circular or chamfered. In this way, the deflection behavior of the vehicle component is improved so as to ensure that the vehicle component can slide down along the deflection element in the direction of the ground without the use of large forces and without getting stuck in the deflection element in any way. In the case of the chamfered contact surface of the vehicle component, the chamfered contact surface can be configured, for example, to be complementary to the contact surface of the deflection element with which it comes into contact.

[0018] According to another advantageous embodiment, the deflection element is arranged spaced apart from the side or rear of the battery receptacle or in contact with the battery receptacle. The arrangement of the deflection element spaced apart from the side and / or rear of the battery receptacle serves to prevent, as far as possible, the transfer of loads from the deflection element to the battery receptacle and thus ultimately also to the battery. By the contact between the deflection element and the battery receptacle, the deflection element can be supported on the side or front of the battery receptacle, thereby resulting in a more robust assembly. Moreover, the deflection element in contact with the battery receptacle can be fixed to the battery receptacle to further increase the robustness of the resulting assembly.

[0019] Another advantageous embodiment provides that a motor vehicle comprises at least one holding unit which holds the battery at least partly in the battery receptacle and comprises two H-shaped holding clamps which are arranged on the sides of the battery with respect to the transverse direction of the vehicle, and the holding unit is attached to the rear floor by means of the two H-shaped holding clamps. The holding unit can completely or partly surround the battery. The holding unit can be formed from individual holding elements connected together to form a lightweight holding structure. The holding unit together with the battery can form a substantially non-deformable assembly. The holding unit can be partly or wholly made of metal, metal alloy, composite material or plastic. By means of the holding unit, the battery is held firmly in the correct position in the battery receptacle during normal operation of the motor vehicle. By selecting a specific material (such as metal, metal alloy or plastic) for the holding clamps, the deformation characteristics of the holding unit can be adapted to the respective requirements. The holding unit can also be mounted 90° rotated under the vehicle and, together with the holding clamps, is arranged on one side of the battery with respect to the longitudinal direction of the vehicle.

[0020] Each H-shaped holding clamp of the holding structure comprises two vertical elements and a horizontal web, the two vertical elements being fixed at least indirectly to the rear floor at the upper ends of the vertical elements by fixing tabs arranged at an angle thereto, the horizontal web extending transversely to the elements and connecting the elements together at the centre, and the battery can be attached to the horizontal web.

[0021] For example, if the rear vertical element of the corresponding H-shaped retaining fixture is mechanically loaded in the case of a rear-end collision and / or relevant plastic deformation of the battery receptacle, the rear element can be elastically deformed in particular and move partially forward away from the rear element fixing point on the rear floor. Accordingly, the rear element simultaneously pushes the front element forward and deforms the front element, especially elastically, through the web. Thus, the battery can be moved forward and simultaneously lifted by the H-shaped retaining fixture or the retaining structure so as to be deflected at least partially forward and upward, thereby avoiding the rear-end mechanical load on the battery due to physical contact with the rear part of the battery receptacle and thus preventing damage to the battery. It is suitable that the battery is inseparably connected to the retaining unit (i.e., the corresponding retaining fixture (swing)) so that the battery is not unsecured at any time. Thus, relative displacement towards the retaining fixture is avoided to prevent loading on the battery and / or the battery getting stuck on surrounding components. The retaining fixture achieves this task as a durable battery receptacle: because it still does not fail despite deformation. The battery is not lifted out of the battery receptacle but only out of the floor tray. Depending on the surrounding components, slight movement of the battery relative to the retaining fixture can obviously be allowed, which can be specified individually. However, in an ideal configuration, the connection of the battery to the retaining fixture should be considered inseparable. By deflecting the battery, additional vehicle parts are exposed to absorb impact energy, which further improves the accident characteristics of the motor vehicle.

[0022] Particularly in the case of a rear-end collision where a vehicle component contacts the lower part of the battery receptacle, the forward displacement and lifting of the described battery are advantageous because in this way the battery receptacle plastically (especially in the floor area) deforms, and thus force is exerted on the lower free end of the rear element of each retaining fixture. Due to the strong lever effect, the retaining fixture deforms optimally as described above.

[0023] If the rear-end mechanical load on the retaining fixture is removed again (e.g., by disassembling vehicle components and dealing with the battery receptacle), the vertical elements of the retaining fixture (if they are fully elastically deformed during the collision) can automatically (due to the internal restoring force of the retaining fixture) return to the undeformed state of the retaining fixture. Thus, the battery is mounted on the rear floor by the retaining unit so as to oscillate to a certain extent in the longitudinal direction of the vehicle. The retaining unit can be configured and set such that the battery (especially under a high rear-end mechanical load) can pivot to a position where the battery is completely above the rear axle. In this way, further rear-end mechanical load on the retaining unit and the battery can be reduced or prevented. Moreover, in this way, additional parts can be exposed to absorb impact energy to further improve the accident characteristics of the motor vehicle.

[0024] According to another advantageous embodiment, the retaining fixture is attached to the rear floor via a fixing point that can vary in the longitudinal direction of the vehicle and / or the lateral direction of the vehicle. In this way, during a rear-end collision, the retaining fixture or the retaining unit can additionally move forward or laterally by a certain degree to prevent high mechanical loads on the battery. In this way, additional portions can also be exposed to absorb impact energy in order to further improve the accident characteristics of the motor vehicle. It can be provided that, during a rear-end collision, the retaining unit first moves forward or laterally, and if necessary, after this displacement, pivots forward or laterally and simultaneously upward via the above-mentioned retaining fixture.

[0025] According to another advantageous embodiment, the motor vehicle includes at least one support element that is disposed between the battery and a spare wheel disposed on or above the rear floor, and the retaining unit is attached to the at least one support element. In this way, during a collision event, direct physical contact between the battery and the spare wheel that shifts relative to the battery during the collision can be reliably avoided. Instead, mechanical loads are only transferred from the spare wheel to the battery via the support element. The support element can be configured such that the support element does not impede the above-mentioned displacement or pivoting of the battery via the retaining fixture in the case of a collision. The support element can be made of metal, metal alloy, plastic, or composite material. The support element can be formed as a metal strip, where angled portions extend in opposite directions at the ends. The support element can be produced from the corresponding material by a 3D printing process. Optionally, the support element can be formed from individual components that are connected together (e.g., glued together). The motor vehicle can also have two or more corresponding support elements.

[0026] In another advantageous embodiment, the support element is formed in a Z shape. The Z-shaped support element can have two legs that face each other, and each leg projects at a right angle from a central portion. The leg facing the battery can be attached to the rear retaining unit. Description of the Drawings

[0036] As needed, detailed embodiments of the present disclosure are disclosed herein; however, it should be understood that the disclosed embodiments are merely examples of the present disclosure, which may be implemented in various and alternative forms. The drawings are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Thus, the specific structural and functional details disclosed herein should not be construed as limiting, but merely as a representative basis for teaching those skilled in the art to use the present disclosure in various ways.

[0037] In the various figures, the same components are always provided with the same reference numerals, and thus these components are generally only described once.

[0038] Figure 1 A schematic cross-sectional view showing an exemplary embodiment of a motor vehicle 1 according to the present invention, wherein Figure 1 only the lower rear part in the area of the trunk 2 of the motor vehicle 1 is shown in a longitudinal section.

[0039] The motor vehicle 1 has a sprung mass 3, which is elastic relative to the rear axle 4 of the motor vehicle 1 in the shown rear part. In addition, the motor vehicle 1 has a vehicle component 5 provided at the rear of the rear axle 4, and the vehicle component 5 is in the form of an exhaust component (especially an exhaust muffler). In addition, the motor vehicle 1 has a battery receptacle 7 in the form of a tray, and the battery receptacle 7 is partially provided on the rear floor 6 of the motor vehicle 1, between the rear axle 4 and the vehicle component 5. In addition, the motor vehicle 1 has a battery 8 partially provided in the battery receptacle 7. A spare wheel receptacle 9 is formed on the rear floor 6 defining the floor of the trunk 2, and a spare wheel 10 can be partially provided and fixed in the spare wheel receptacle 9 by a fixing device 11.

[0040] In addition, the motor vehicle 1 includes three deflection elements 12 which are spaced apart from each other in the vehicle transverse direction and are arranged between the battery receptacle 7 and the vehicle component 5, and Figure 1 only one deflection element 1 is shown; the deflection elements are each configured such that the respective deflection element 12 presses against the vehicle component 5 which contacts the respective deflection element 12 upon forward displacement of the vehicle component 5 and moves downward in the ground direction when continuing to move forward. For this purpose, each deflection element 12 includes a triangular rib 13 which extends parallel to the vehicle longitudinal direction and tapers in the ground direction. Such deflection elements 12 are Figure 2 and Figure 3 shown in various perspectives, where Figure 2 and Figure 3 in particular, a part of the deflection element 12 which contacts the vehicle component 5 is shown as being planar. Figure 1 It is also shown that the surface of the vehicle component 5 intended to contact the respective deflection element 12 (i.e., Figure 1 the surface of the vehicle component 5 shown on the left side in

[0041] is formed as circular. Optionally, this surface can be chamfered in a manner complementary to the chamfer shown for the respective deflection element 12. Each deflection element 12 is arranged to contact the rear floor 6 and the battery receptacle 7 and can be fixed to the rear floor 6 and the battery receptacle 7. Optionally, each deflection element 12 can be arranged to be spaced apart from the rear of the battery receptacle 7. Figures 4 to 6 The motor vehicle 1 also includes a holding unit 14 which holds the battery 8 partially in the battery receptacle 7 and includes two H-shaped holding clamps, as Figure 1 shown, the two H-shaped holding clamps are arranged on one side of the battery 8 with respect to the vehicle transverse direction extending perpendicular to the drawing plane, and the holding unit 14 is attached to the rear floor 6 by means of the two H-shaped holding clamps.

[0042] In addition, the motor vehicle 1 has a support element, as Figure 4 and 8 shown, the support element is arranged between the battery 8 and the spare wheel 10 arranged on or above the rear floor 6 and is attached to the holding unit. As Figure 4 and 8 shown, the support element is configured as Z-shaped.

[0043] Figure 2 shows Figure 1Schematic perspective view of the deflection element 12 shown in []. The deflection element 12 includes ribs 13 formed as right-angled triangles. The angled portions 16 and 17 are adjacent to the ribs 13 on their two short sides and extend at right angles to the ribs 13 to provide surfaces for fixing the deflection element to Figure 1 the rear floor 6 shown in []. and / or for fixing to Figure 1 the adjacent or fixing surfaces of the battery receptacle 7 shown in []. A single recess 18 is provided in the transition region from the rib 13 to the angled portion 16, and two additional recesses 18 are provided spaced apart from each other in the transition region from the rib 13 to the angled portion 17 to increase the inherent stability of the deflection element 12. An angled portion 19 is provided on the longest side of the rib 13, whereby a part of the deflection element 12 that contacts the Figure 1 vehicle component 5 shown in []. during a rear-end collision forms a plane. The angled portion 19 can be integrally formed with the rib 13. Alternatively, the angled portion 19 can be produced separately and connected to the rib 13 by a material bond.

[0044] Figure 3 Shows Figure 1 another schematic perspective view of the deflection element 12 shown in []. In this perspective view, the angled portion 16 is shown inclined from above, while the viewing direction is parallel to the longitudinal extension of the angled portion 19. To avoid repetition, reference is additionally made to the above description of Figure 2 [].

[0045] Figure 4 Shows Figure 1 a schematic perspective view of the holding unit 14 and the battery 8 held by the holding unit 14 shown in []. Figure 4 Also shown are three deflection elements 12 spaced apart from each other in the vehicle transverse direction, the description of which refers to the above description of Figures 1 to 3 [].

[0046] Shows the H-shaped holding clamp 20 of the holding unit 14, the H-shaped holding clamp 20 being provided on the side of the battery 8 with respect to the vehicle transverse direction. Each holding clamp 20 includes two vertical holding elements 21 extending parallel to each other, where a web 22 connects the two holding elements 21 together substantially at the center. At the upper end of each holding element 21 is a tab-shaped angled portion 23, and the respective holding clamp 20 is fixed to the Figure 1 rear floor 6 shown in [].

[0047] In addition, the holding unit 14 has a reinforcing longitudinal element 24 provided on the long side of the battery 8, and reinforcing connecting elements 25 and 26 provided substantially at the center of the battery 8, and the longitudinal element 24 is connected together by the reinforcing connecting elements 25 and 26. In this way, the assembly formed by the holding unit 14 and the battery 8 is substantially non-deformable.

[0048] The Z-shaped support element 27 is fixed to the longitudinal element 24 and / or the connecting element 25, and in a collision event, mechanical loads can be transmitted through this element 27 from Figure 1 the spare wheel 10 shown in Figure 4 to the retaining element 14. The support element 27 includes a vertical central portion 28 or web, which connects two mutually opposed portions 29 and 30 of the support element 27 together, and each portion is at a right angle to the central portion 28. The portion 30 is fixed to the retaining element 14 and is shown in dashed lines in Figure 8 the view of

[0049] Figure 5 The retaining clamp 20 (shown on the left side in Figure 4 the retaining unit 14 shown in Figure 4 ) of the normal state of a motor vehicle (not shown) is shown in an undeformed state. The retaining element 21 of the retaining clamp 20 does not deform.

[0050] Figure 6 A schematic view of the retaining clamp 20 of the retaining unit 14 shown in Figure 4 in a deformed state is shown. The force acting on the lower part of the retaining clamp 20 from the right side in Figure 6 causes the retaining element 21 to deform, as shown on the right side in Figure 6 , and therefore the retaining element 21 shown on the left side must also be deformed via the web 22. In this way, the battery 8 connected to the retaining clamp 20 (as shown in Figure 6 and Figure 1 and 4 ) moves forward and upward.

[0051] Figure 7 A schematic cross-sectional view of the motor vehicle 1 shown in Figure 1 is shown in four different deformed states. Obviously, in a rear-end collision, the vehicle component 5 in the form of an exhaust muffler is deflected downward in the direction of the ground by a deflection element (not shown) and also rotates. It is also obvious that the battery 8 is displaced or pivoted forward and upward during the collision.

[0052] Figure 8 A schematic side view of the support element 27 shown in Figure 4 in a deformed state (shown by dashed lines) and in an undeformed state (shown by solid lines) is shown. It can be seen that in the undeformed state of the support element 27, the portions 29 and 30 are disposed at a right angle to the central portion 28. In the event of a collision, a vertical mechanical load can act on the support element 27, whereby the support element 27 can deform (as shown) without limitationFigure 1 , 4 and the above-described pivotability of the battery shown in 7.

[0053] Although the above describes exemplary embodiments, it does not mean that these embodiments describe all possible forms of the present disclosure. On the contrary, the words used in the specification are descriptive rather than restrictive, and it should be understood that various changes can be made without departing from the spirit and scope of the present disclosure. Additionally, the features of various implementation embodiments can be combined to form other embodiments of the present disclosure.
