Description

Technical Field

[0001] The invention relates to a battery holder according to the features of the preamble of claim 1 . Background Art

[0002] In order to fix the battery elements for providing electrical energy in electrically driven vehicles, a battery tray is used, which is arranged between the axles of the vehicle. An important safety requirement for the battery tray includes good crash performance. In order to meet this, the battery tray is protected by an external reinforcement structure.

[0003] DE 10 2018 126 068 A1 discloses a battery carrier for an electric vehicle. The battery carrier has a battery tray which is embedded in an outer frame and is closed by a cover. The frame is made of at least two mutually engaged profile components in cross section, at least one of which is made as a sheet metal profile.

[0004] EP 3 468 821 B1 discloses a battery box for a motor vehicle, which has a structural frame, which serves as a reinforcement structure. The structural frame can be connected to the motor vehicle body via fixing means, which are designed as sleeves. These sleeves extend between the upper side and the lower side of the fixing section in the profile section of the structural frame and are essentially positively secured to prevent lateral movement.

[0005] The battery tray must be mechanically stable and fixed to the body or chassis of the vehicle. The battery tray should be integrated into the vehicle body to a large extent, which creates challenges in terms of design and installation technology.

[0006] The outer reinforcement structure in front of the side wall of the battery tray consists of several components as well as built-in elements and accessories. These components are welded to each other and to the battery tray. The large number of individual components and the large number of welded connections can lead to deformations in the welded structure. The large number of individual components also leads to increased tolerances or tolerance chains. These and welding deformations must be compensated to ensure that the battery tray is suitable for mass connection in motor vehicles. The battery tray itself is fixed to the body or chassis of the vehicle by means of fixing devices, usually screw connection devices. The battery tray is especially fixed to the side sills and, if necessary, to the floor cross member in the motor vehicle. The tightening points here constitute the interface for the vehicle body, so that very high requirements are placed on their positioning accuracy. Summary of the invention

[0007] Starting from this prior art, the object of the invention is to provide a battery bracket which is improved in terms of function and installation technology and has flexible adjustment possibilities and a high position accuracy of the mounting points.

[0008] This object is achieved by a battery holder according to claim 1 .

[0009] Advantageous embodiments and developments of the battery carrier according to the invention are the subject of the dependent claims.

[0010] A battery bracket for holding a battery element for providing electrical energy in an electric vehicle comprises a battery tray having a reinforcement structure, which is arranged on the outside in front of at least one side wall of the battery tray. The reinforcement structure extends in the longitudinal direction of the side wall and comprises a hollow profile, which is preferably formed by an inner profile and a closing plate. The inner profile and the closing plate form a box-shaped hollow profile at least over most of the length of the reinforcement structure. The inner profile is configured in a U-shape in cross section and has a rear tab and an upper first leg and a lower second leg. An opening is provided in each leg. The tab is oriented parallel to the side wall of the battery tray. The upper leg and the lower leg of the inner profile are oriented away from the battery tray, so that the open side of the inner profile is located on the outside. The open side of the inner profile is closed by a closing plate at least over a partial length section.

[0011] The closing plate can be designed in the form of a shell or can be profiled in the manner of a shell and have an outer wall and webs, in particular joining webs, which protrude in the direction of the inner profile.

[0012] The hollow profile of the reinforcing structure can also be a single-chamber profile or a multi-chamber profile. The sleeve is then preferably pushed from below through the opening in the leg and guided through the passage in the counter washer.

[0013] A plurality of sleeves are provided in the reinforcement structure, which are fixing or mounting sleeves, which are in particular designed to be cylindrical or rectangular. Typically, a plurality of sleeves spaced apart from one another are provided in the longitudinal direction of the reinforcement structure. The sleeves extend over the entire height of the hollow profile between the legs of the hollow profile. The sleeves connect the openings in the legs, wherein sleeve sections, in particular the sleeve sections at the upper ends of the sleeves, protrude from the openings in the upper first leg. The sleeves are used to pass through fixing means, by means of which the battery bracket is fixed in the vehicle body or chassis. In particular, the battery bracket is fixed to the side sill and, if necessary, the floor bracket in the motor vehicle by means of sleeves and suitable fixing means.

[0014] The opening in the leg can be closed per se and have a circumferential edge. The opening can be designed to be circular, for example.

[0015] An advantageous embodiment provides that at least one opening, in particular the first opening in the upper first leg, is open on the edge. The opening is preferably designed as a slot in the first leg. This is an elongated opening in the first leg, which starts from the free end of the leg. This slot-like or elongated hole-like opening is oriented in the first leg transversely to the longitudinal axis of the hollow profile.

[0016] According to the invention, a counter washer is provided with a through-hole for the sleeve, through which the sleeve passes with a sleeve section, and the counter washer at least partially, in particular completely, covers the first opening in the first leg or the second opening in the second leg.

[0017] "Covering" means that the gasket surrounds the sleeve with the passage and closes the remaining space between the edge of the opening and the sleeve. In this case, the gasket can rest on the leg or on the underside. In particular, the gasket overlaps the opening in the first leg or the opening in the second leg at the top or at the bottom. In particular, the gasket rests on the outside on the first leg. The gasket then rests with the overlap on the edge that delimits the opening in the first leg.

[0018] The shims are provided and determined for compensating tolerances in the assembly of the reinforcement structure and / or for adjusting the position of the sleeve in the hollow profile during assembly or after assembly and before the sleeve is engaged. The shims serve to compensate for tolerances and distances between the components of the reinforcement structure and serve as positioning elements for the sleeve in the reinforcement structure and thus for adjusting the mounting point and its position.

[0019] The mating gasket overlaps the edge surrounding or adjacent to the opening in the first leg or in the second leg at the top. When the mating gasket is arranged below the opening, the mating gasket overlaps the opening at the edge side at the bottom. The upper overlap or the lower overlap is so large that the mating gasket and the sleeve passing through the through-portion can be positioned and oriented and the opening is covered by the mating gasket.

[0020] The counter-waster can be positioned in a receptacle in the leg. The receptacle is formed in particular by a recess in one of the legs, in particular in the first leg.

[0021] A particularly advantageous design provides that the passage has a flange, in particular a peripheral flange that is closed in itself, with which the passage surrounds the outer circumference of the sleeve. This is advantageous in terms of function and also in terms of assembly technology.

[0022] The flange is oriented in particular outwardly away from the hollow profile. However, the flange can also be oriented inwardly into the hollow profile. In particular, the flange is oriented inwardly into the interior of the hollow profile when the counter washer is arranged on the inner side of the hollow profile and rests on the legs on the inner side of the hollow profile and covers the corresponding opening.

[0023] A particularly advantageous embodiment for practical purposes provides that the hollow profile comprises an inner profile and a closing plate, wherein the inner profile is U-shaped in cross section and has a rear tab and the first leg and the second leg. The two legs of the inner profile are oriented away from the battery tray, i.e., point outwardly when viewed from the battery tray. The inner profile is closed at least over a partial length section by the closing plate.

[0024] This design is advantageous functionally and in terms of crash behavior. The stiffness properties of the reinforcement structure are load-optimized. The inner profile is easily accessible via the open side. This improves functionality, in particular the accessibility and installation of the inner profile itself and of the built-in components to be installed in the inner profile. The inner profile and the closing plate complement each other synergistically to form a hollow profile of the reinforcement structure. The hollow profile is characterized by advantageous static and dynamic load properties. In particular, the stiffness of the reinforcement structure relative to the battery tray is high. In this case, the legs of the inner profile or hollow profile can be deformed in the event of a side impact and energy dissipation, wherein the closing plate acts as a tie rod and holds the legs in position to a certain extent.

[0025] Another advantageous embodiment provides that the sleeve or sleeves are guided with an upper sleeve section through a first opening in the first leg and protrude relative to the outer side of the first leg. It is also possible that the sleeve or sleeves are guided with a lower sleeve section through a second opening in the second leg and protrude relative to the outer side of the second leg. The protruding or protruding section of the sleeve is used in particular as a connecting surface for a material-locking connection with a counter washer, in particular in the form of an at least partially circumferential weld seam or a positive and / or non-positive joint connection such as a crimp or crimp.

[0026] Another advantageous embodiment provides that the sleeve has an upper and / or lower collar. The sleeve has a sleeve body. An especially circumferential collar is arranged at one or both ends of the sleeve body. The collar is oriented outward from the sleeve body. In particular, the collar material is a uniform component of the sleeve or the sleeve body.

[0027] The collar can also be formed by a separate collar body, in particular a ring. The collar therefore constitutes an annular step on the outer surface of a roughly cylindrical sleeve body. But within the scope of the present invention, one or more sleeves can also have a polygonal basic shape.

[0028] Preferably, the sleeve has a lower collar. By means of the lower collar at the lower end of the sleeve body, the sleeve stands on the inside on the second lower leg. The lower collar in particular increases and functionally improves the contact surface for engagement with the second leg.

[0029] Instead of the collar, a second mating washer can also be provided which has the same function as the collar of the sleeve.

[0030] It is also possible for the sleeve to pass with the sleeve body through the second opening in the lower second leg and for the lower collar to rest on the outer side against the second leg.

[0031] The collar absorbs the friction and pressure generated when tightening the installation element such as the screw connection element guided through the sleeve or sleeve body. The surface of the component in the screw connection area can be protected from damage and the surface pressure can be reduced.

[0032] The legs of the hollow profile or the legs of the inner profile and / or the closing plate can have engaging tongues. Preferably, a plurality of engaging tongues spaced apart from each other are arranged in the longitudinal direction of the inner profile along the longitudinal edge section of the leg. The engaging tongues protrude outwardly in a directed manner. Preferably, alternating rows of engaging tongues are arranged along its longitudinal edge section on each leg. These engaging tongues are spaced apart from each other in the longitudinal direction of the leg so that there is free space between the engaging tongues respectively. The closing plate is supported on the free end or the longitudinal edge section of the leg and / or on the engaging tongues of the leg. The engaging tongues can be arranged at an angle relative to the leg, the engaging tongues being particularly directed outwardly away from the free end of the leg. This improves accessibility, in particular accessibility when producing spot welding connections.

[0033] The closing plate can also have a joint tongue or a joint tab, which is supported on the legs of the inner profile. In particular, the closing plate is partially against the joint tongue with the joint tab.

[0034] The closing plate is connected to the inner profile in a material-locking manner. This is achieved by a material-locking connection between the joining tongues of the inner profile and the joining tabs of the closing plate. In particular, the material-locking connection between the joining tongues and the joining tabs is achieved by a spot welding connection or spot welding adhesive bonding. These joining techniques ensure that less heat is input into the component during the material-locking connection. In principle, roller seam welding (Rollnahtschweissen) or laser welding is also possible.

[0035] Another advantageous embodiment provides that built-in elements are provided in the reinforcement structure. The built-in elements can be load guides, partitions and similar internally located reinforcement and / or functional components. The built-in elements are arranged in particular adjacent to internal struts arranged in the battery tray. The built-in components are located in the reinforcement structure laterally in front of the internal struts, which extend in the battery tray between the opposite side walls of the battery tray.

[0036] The built-in element is preferably designed as an open or closed profile sheet metal and extends between the first leg and the second leg of the hollow profile and / or as a continuous load path from the closing plate to the inner profile. The internal reinforcement member can also be designed as a patch or local material doubling.

[0037] Furthermore, at least one support beam and / or protective plate can be provided below the battery tray and / or below the reinforcement structure. The support beam and / or protective plate can have different functions. In particular, they contribute to the maintenance of the battery weight, i.e., to the bearing weight and / or load, or serve as additional protection, in particular against penetration or tearing from below and as side impact protection.

[0038] The reinforcement structure is connected to the battery tray. For this purpose, the internal profile is engaged with the battery tray. In particular, the internal profile is engaged with its rear tabs against the side wall of the battery tray. The open internal profile is advantageously accessible from the side. The sleeve and other built-in components can be placed and installed in the open internal profile. The orientation and adjustment of the sleeve are achieved with the help of a matching gasket during installation. Before the sleeve is engaged, the tolerance is compensated and the mounting point is set precisely in position by adjusting the position of the sleeve in the hollow profile. The sleeve or its sleeve body can move in the opening in a limited manner in the longitudinal direction and transverse direction of the hollow profile or the reinforcement structure. In addition, the inclination of the longitudinal axis of the sleeve relative to the vertical line can be adjusted to a limited extent. The opening is covered by a matching gasket and the position of the sleeve and therefore the position of the mounting point is determined. For this purpose, the matching gasket is engaged with the leg in a material-locked manner. The matching gasket is against the adjacent leg. In particular, the matching gasket is against the first leg, i.e. the upper leg of the internal profile, on the outside. The material-locked connection between the matching gasket and the leg is achieved in particular by welding.

[0039] After the sleeve and, if necessary, the built-in element are installed in the inner profile, the open side of the inner profile is closed by one or more closing plates. This is achieved in a material-locked manner, preferably with welding technology.

[0040] In addition to the built-in elements in the reinforcement structure, reinforcement or stiffening elements can also be integrated in the battery tray. Such reinforcement or stiffening elements can be formed by longitudinal and / or transverse profiles or struts extending on the tray bottom.

[0041] Furthermore, the cover can form the upper closure of the battery tray. It is particularly advantageous if the battery tray is designed and intended for integration into the body or chassis of the vehicle. The battery tray forms a load-bearing component of the body (battery to body). The floor of the vehicle can form the battery cover.

[0042] The battery tray is in particular a deep-drawn part which is constructed in one piece and of uniform material. The inner profile and / or the closing plate can also be made by die-casting or deep-drawing technology. Due to its U-shaped cross-section, the inner profile has a channel-like extension, in which a plurality of sleeves are arranged at intervals from one another in the longitudinal direction. The at least one closing plate closes the inner profile over at least a portion of its length. In this way, the inner profile and the closing plate form a hollow profile. A plurality of closing plates can be arranged in the longitudinal direction of the reinforcement structure. The one closing plate or the plurality of closing plates form the outer wall of the reinforcement structure.

[0043] The battery tray can also be formed into a battery tray from a sheet metal blank by folding technology. For this purpose, a sheet metal blank is provided, the geometry of which corresponds to the unfolded shape of the battery tray. The cooling plate can optionally be directly joined to the sheet metal blank, which is then formed into a battery tray by folding technology. The battery tray is constructed as a folding component. The folded corners of the battery tray are joined and sealed.

[0044] The battery tray as well as the reinforcement structure and the components forming the reinforcement structure, in particular the inner profile and / or the closing plate, can be produced by die quenching the steel sheet. Die quenching is also called press quenching. During die quenching, the metal sheet made of manganese-boron steel is heated to a temperature above the specific austenitizing temperature of the material, placed in a forming mold and hot-formed into a molded part, which cools during the forming process. When clamped in the forming mold, the molded part is quenched by cooling.

[0045] Coated hardenable steel sheets can also be used here. In particular, these are manganese-boron steel sheets provided with an aluminum / silicon coating with a zinc alloy coating. The components of the reinforcement structure and the battery tray have a tensile strength of 1000 MPa and above.

[0046] The battery tray and the inner and / or outer profiles of the reinforcement structure can also be made of extremely high and ultra-high strength cold-formed steel. At least the outer profile has a tensile strength greater than 980 MPa. In particular, the inner profile has a tensile strength greater than or equal to 1180 MPa.

[0047] The battery tray and the components of the reinforcing structure, in particular the inner profiles and / or the outer profiles, can be made of customized sheets (Tailored Blanks). Tailored blanks with different metal sheet thicknesses and / or material grades can be used here. Components with customized strength properties can also be used. Not only the battery tray but also the inner profiles and / or the outer profiles can have local soft areas (Soft Zones). These measures are used to increase the lateral rigidity and improve the crash performance in a targeted manner and, for example, to prevent cracks during welding or to adjust local weakened areas that have improved deformation capacity to absorb energy.

[0059] exist Figures 1 to 14In the description, the same reference numerals are used for components or component parts that are identical or correspond functionally to one another, even if a repeated description is omitted for reasons of simplicity.

[0060] Figures 1 to 3 as well as Fig.13 and Fig.14 A battery tray 1 and its components according to the present invention are shown.

[0061] The battery support 1 has a battery tray 2 deep-drawn from a steel sheet. The battery tray 2 is rectangular in cross section and has a tray bottom 3 and side walls, namely two longitudinal walls 4, 5 and two end walls 6, 7, which complement each other to form a surrounding tray wall 8. At the upper tray edge 9, an outwardly directed flange section 10 extends along the longitudinal walls 4, 5 and the end walls 6, 7, which also complement each other in a surrounding closed manner to form an upper flange 11. The tray wall 8 defines a tray interior space 12 of the battery tray 2.

[0062] Optionally and as in Figure 2 and Fig.13 and Fig.14 As schematically shown in FIG. 1 , a plurality of internal struts 13 are arranged in the tray interior 12 . The internal struts 13 extend transversely on the tray bottom 3 between the longitudinal walls 4 , 5 and are fixed in the battery tray 2 in a material-locking manner.

[0063] On the top, the battery tray 2 is closed by a cover 14 which rests on the flange 11 at the edge with the interposition of a circumferential seal (not shown here). In the illustrated embodiment, the cover 14 is detachably connected to the battery tray 2 by means of screw connections 15.

[0064] The battery tray 1 has a reinforcement structure 16. The reinforcement structure 16 extends outside the battery tray 2 in front of the longitudinal walls 4, 5 respectively.

[0065] As especially Figure 1 as well as Figure 4 and Figure 5 and Figures 6 to 10 As shown, the reinforcement structure 16 has an inner profile 17 and a closing plate 18. The inner profile 17 is U-shaped in cross section and has a rear tab 19 as well as an upper first leg 20 and a lower second leg 21 and an open side 22. The legs 20, 21 of the inner profile 17 are oriented away from the battery tray 2. The tab 19 extends parallel to the side walls or respectively parallel to the longitudinal walls 4, 5. The open side 22 of the inner profile 17 is closed by the closing plate 18 at least over a partial length section.

[0066] Both the inner profile 17 and the closing plate 18 are sheet metal profiles formed from sheet steel. These can be die-hardened sheet steel components or cold-formed profiles made of, in particular, ultra-high-strength (UHSS) cold-formed steels.

[0067] The reinforcement structure 16 extends in the longitudinal direction LR of the longitudinal walls 4, 5. The inner profile 17 and the closing plate 18 form a hollow profile 23 at least over a large part of the length L of the reinforcement structure 16.

[0068] A plurality of sleeves 24 are arranged in the hollow profile 23 of the reinforcement structure 16. These sleeves extend vertically between the first leg 20 and the second leg 21 of the inner profile 17. A first opening 25 is arranged in the upper first leg 20 and a second opening 26 is arranged in the lower second leg 21. The openings 25, 26 are connected by sleeves (see also Figures 6 to 10 ). The sleeve 24 has a sleeve body 27 and projects beyond the first upper opening 25 with a sleeve section 28. On the upper side, the first opening 25 is covered by a gasket 29, 30. The gaskets 29, 30 have a through-hole 31. The sleeve 24 projects through the through-hole 31 with the sleeve section 28 and projects at the upper side relative to the first leg 20 of the inner profile 17.

[0069] exist Fig.11 and Fig.12 Two embodiments of the mating gaskets 29 and 30 are shown in FIG. Fig.11 The illustrated mating gasket 29 comprises a flat gasket body 31 having a through-portion 32. Fig.12 The illustrated gasket 30 also has a flat gasket body 31, wherein the through-hole 32 has a self-closed circumferential flange 33. The circumferential flange 33 in the gasket 30 is pulled out of the gasket body 31 in a unified, one-piece manner in the form of a bead. The semi-finished product for producing the gasket 30 can be as follows: Fig.11 The gasket body 31 shown in FIG.

[0070] The first opening 25 in the first leg 20 can be closed per se, ie, circumferentially defined by an edge. Such an opening 25 is, for example, circular. The circular first opening 25 is preferably Figure 1 , Figure 5 as well as Figures 7 to 10 and Fig.13 The embodiment shown is shown.

[0071] The first opening 25 in the upper first leg 20 can also be open at the edge side to the front toward the free end of the leg 20 and the outer profile 18. Figure 6 In this embodiment, the opening 25 is designed in the form of a slot or an elongated hole and is open at the free end of the leg 20 .

[0072] At the lower end, the sleeve 24 has a lower collar 34. The collar 34 can be formed by a sheet-like element 35. However, the collar 34 can also be formed by a deflection at the lower end of the sleeve body 27 of the sleeve 24. The sleeve 24 stands on the inner side on the lower second leg 21 by means of the lower collar 34.

[0073] The washers 29, 30 are provided and defined for compensating tolerances and adjusting the position of the sleeve 24 in the hollow profile 23 before the sleeve 24 is joined and thus defining the final position of the mounting point provided or realized by the sleeve 24. For this purpose, the sleeve 24 can be moved relative to the first opening 25 in the first leg 20 and relative to the second opening 26 in the second leg 21. In addition, the inclination of the sleeve longitudinal axis HL relative to the vertical can be set in terms of angle. For this purpose, the washers 29, 30 can be moved on the upper first leg 20 in the longitudinal direction and in the transverse direction of the reinforcement structure 16. After the correct position is adjusted, the sleeve 24 is fixed. For this purpose, the washers 29, 30 are joined to the first leg 20 and the sleeve 24 in a material-locking manner, in particular welded.

[0074] The gasket 29, 30 covers the first opening 25 in the upper first leg 20 with a lap 45. The gasket 29, 30 surrounds the sleeve 24 or the sleeve section 28 and projects outwards in such a way that it projects beyond the edge 46 of the opening 25 and thus covers the opening 25. In the region of the lap 45, the gasket 29, 30 is then at least partially engaged with the first leg 20.

[0075] In accordance with Figure 7 and Fig. 9 In the embodiment of the inner profile 17 shown, the first leg 20 and the lower leg 21 can have engaging tongues 36. The engaging tongues 36 extend outwards on the longitudinal edge sections of the legs 20, 21. A plurality of engaging tongues 36 are arranged alternately along the length of the inner profile 17. There are free spaces 37 between the individual engaging tongues 36.

[0076] The closing plate 18 has engaging tabs 38. These extend along the outer longitudinal edges of the closing plate 18. The closing plate 18 rests on the inner profile 17 in the region of the engaging tongues 36 by means of the engaging tabs 38. In the region of the free space 37, the closing plate 18 rests on the legs 20, 21 of the inner profile 17 by means of the outer engaging tabs 38 at the longitudinal edges of the inner profile.

[0077] The closing plate has an outer wall 39. The outer wall 39 extends vertically in cross section, essentially parallel to the rear tab 19 of the inner profile 17. A joining tab 38 is provided at the upper and lower longitudinal edges of the closing plate 18. The joining tabs are oriented transversely to the outer wall 39.

[0078] In accordance with Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Fig.13 In the embodiment of the closing plate 18 shown, the joining webs 38 are turned inwardly in the direction of the inner profile 17 .

[0079] In accordance with Figure 7 and Fig. 9 In the embodiment of the closure plate 18 shown, the joining web 38 is oriented outwardly away from the end of the first leg 20 and / or the second leg 21 .

[0080] The insertion of the sleeve 24 and the installation and fixing of the internal elements are carried out from the outside with the inner profile 17 open, and then the inner profile is closed at least over a part of the length section by the closing plate 18. For this purpose, the closing plate 18 is joined to the inner profile 17 in a materially bonded manner, in particular by spot welding. This is carried out in particular between the joining tongues 36 and the joining tabs 38.

[0081] according to Fig.13 and Fig.14 The embodiment of the battery tray 2 shown in corresponds to the above-described basic structure. An internal element 40 is shown in simplified form, which is built into the hollow profile 23 or the inner profile 17 of the reinforcement structure 16. Such an internal element 40 can be, for example, a load guide or a partition. They are joined to the inner profile 17, in particular in a material-locking manner. Figure 3 in the view and in Fig.14 In FIG. 4 , an integrated element 40 is shown in a technically simplified manner, which is designed in the shape of a hat and has different heights.

[0082] A support beam 41 may be provided below the battery tray 2 and the reinforcement structure 16. Figure 1 In the embodiment shown, the support beam 41 has a hole 42, which is connected to the lower leg 21 and the lower opening 26 in the sleeve 24. The support beam 41 can be configured in a plate-like or profiled manner.

[0083] In addition, Figure 1The left half of the figure also implicitly shows the side sill 43 of the motor vehicle and the connection of the battery bracket 1 to the motor vehicle. A screwing point AP in the form of a threaded sleeve 44 is provided in the motor vehicle or the side sill 43. The sleeve 24 provides mounting points MP, via which the battery bracket 1 is fixed to the motor vehicle by means of threaded connection devices. The final setting of the mounting points MP and therefore the adjustment between the screwing points AP and the mounting points MP is achieved by adjusting and orienting the position of the sleeve 24 in the reinforcement structure 16 via matching washers 29, 30. In order to mount the battery bracket 1, the threaded connection device is guided through the sleeve 24 and is detachably coupled to the threaded sleeve 44.

[0084] Instead of a side sill, the battery bracket 1 can also be fastened to other floor structural elements of the motor vehicle, for example to a longitudinal beam located further inward or to a guide frame longitudinal beam.
