In addition, WO2012 / 159603A1 discloses a side sill for a vehicle body. Summary of the invention

[0003] The object of the present invention is to provide a side sill for a body of a passenger car, a body for a passenger car, a passenger car and a method, which allow the side sill to be produced in a particularly advantageous manner.

[0004] This object is achieved according to the invention by a side sill having the features of claim 1, a body having the features of claim 7, a passenger car having the features of claim 8 and a method having the features of claim 9. Advantageous embodiments of the invention are the subject matter of the dependent claims.

[0005] A first aspect of the invention relates to a side sill for a body of a passenger car (also called a passenger car body). Preferably, the body is a self-supporting body. The side sill has a longitudinal extension direction, wherein the side sill extends at least substantially longitudinally along its longitudinal extension direction. In the fully manufactured state of the passenger car, the longitudinal extension direction or longitudinal extension of the side sill extends in the longitudinal direction of the vehicle (also called the x-direction).

[0006] The side sill has a support element made of steel. In addition, the side sill includes at least one insert, which is made of light metal, in particular aluminum. This means in particular that the insert (also referred to as insert for short) is composed of, i.e., made of, for example, a light metal alloy, in particular an aluminum alloy. The insert is directly bonded to the support element to form at least one bonding seam. The bonding seam is formed by an adhesive, by means of which the insert is directly bonded to the support element. This should be understood in particular to mean that the bonding seam or adhesive is arranged between the insert and the support element, and the insert is in direct contact with the support element accordingly. For example, the bonding seam is also referred to as an adhesive tape, or the bonding seam is configured as an adhesive tape. The insert is partially surrounded by the support element on the peripheral side (in particular only or only), whereby the support element has an open area in the fully manufactured state of the side sill, in particular in the fully manufactured state of the body, and very particularly in the fully manufactured state of the passenger car. Therefore, the open area is an opening, or the open area is also referred to as an opening of the support element. In this open area, the insert is arranged without overlapping relative to the carrier element, that is, the insert is not overlapped or covered by the carrier element in this open area, in particular when viewed from the outside, in other words, it is provided that the insert is avoided from being overlapped or covered by the carrier element in this open area. Furthermore, in the side sill according to the invention, it is provided that, in particular in the fully manufactured state of the side sill, in particular in the fully manufactured state of the vehicle body and very particularly in the fully manufactured state of the passenger car, the adhesive seam directly adjoins the open area in a circumferential direction of the side sill and therefore of the carrier element and the insert extending around the longitudinal extension direction of the side sill. As a result, the adhesive seam is accessible, in particular through this open area, to heat or air, from which heat can be transferred to the adhesive seam, i.e. to the adhesive, so that, for example, the adhesive seam, i.e. the adhesive, can be cured particularly advantageously and in particular completely in the method for producing the side sill. In the method, for example, the side sill is arranged in an oven, in which hot air or heated air is supplied, in particular in the form of circulating air. Since the carrier element now has an open area and the adhesive seam directly adjoins it, the hot or heated air can flow particularly well and in particular directly onto at least a portion of the adhesive seam, so that heat can be transferred particularly advantageously from the air to the adhesive seam. As a result, the adhesive seam or the adhesive can cure particularly well and in particular completely, so that the adhesive seam has a structural function or supporting effect in the fully manufactured state of the side sill, in particular the carrier element and the insert are fixedly connected to each other by means of the adhesive seam, i.e. by means of the adhesive forming the adhesive seam.The side sill according to the invention thus allows the adhesive seam to be cured advantageously and completely, so that, for example, the adhesive seam or adhesive can be taken into account when analyzing, in particular numerically analyzing, the accident properties of the side sill or the deformation of the side sill caused by the accident, in particular the adhesive seam can, for example, absorb and / or transfer the loads caused by the accident and / or at least temporarily ensure that the side sill is structurally held. Due to the fixed connection between the insert and the support element by the adhesive seam, the insert is a reinforcing element that is supported together, in particular fixed to the body-in-white. In other words, the insert is a reinforcing element, by which the side sill is advantageously reinforced. As a result, the side sill can achieve particularly advantageous accident performance. In this case, the insert has a particularly high energy absorption capacity, so that, for example, by the support element, i.e., by the deformation of the support element caused by the accident, the accident energy can be advantageously reduced in the event of an accident, in particular in the following way: the accident energy can be converted into deformation energy. In addition, the invention can avoid costly joining technologies, for example when joining the outer panels or side frames of the side sill or when joining with the side sill.

[0007] In order to achieve a particularly strong connection between the insert and the carrier element without having to use expensive joining techniques, one embodiment of the invention provides that the insert is riveted directly to the carrier element. For example, the insert is riveted directly to the carrier element by means of at least one rivet. It is conceivable that the rivet penetrates the adhesive seam.

[0008] Alternatively or additionally, it is conceivable that the insert is directly screwed to the support element, in particular by means of at least one or exactly one screw, which can be designed as a flow screw (FLS), for example. Alternatively or additionally, for example, the insert can be mechanically connected to the support element of at least one or exactly one additional element.

[0009] Another embodiment is characterized in that the insert is designed as an extruded profile. As a result, the costs of the side sill can be kept particularly low, so that the side sill can be manufactured particularly cost-effectively. In addition, a particularly high energy absorption capacity of the insert can be achieved cost-effectively.

[0010] In order to be able to produce the side sill particularly cost-effectively, it is provided in a further embodiment of the invention that the carrier element has a plurality of bearing parts made of steel, which are designed separately from one another and are connected to one another.

[0011] Here, it has been shown to be particularly advantageous if the support parts are directly welded to one another, in particular by spot welding. Thus, the support parts can be particularly cost-effectively and fixedly connected to one another, so that the side sill can be manufactured particularly cost-effectively.

[0012] Finally, it has proven to be particularly advantageous if the open area extends in a circumferential direction of the side sill extending around the longitudinal extension direction of the side sill over an angular range of at least 30°, in particular at least 45° and very particularly more than 45°, in particular at least and very particularly more than 60°. As a result, the adhesive seam is particularly well accessible to the aforementioned heat or air, whereby the adhesive seam can cure particularly well and completely. The side sill can thus be manufactured particularly cost-effectively.

[0013] The second aspect of the invention relates to a body for a passenger car, which is preferably designed as a self-supporting body and is also referred to as a passenger car body, wherein the body according to the second aspect of the invention has at least one side sill, in particular according to the first aspect of the invention. The side sill has a support element made of steel and at least one insert made of light metal, which is directly bonded to the support element to form at least one bonding seam and is (in particular only) partially surrounded by the support element on the outer circumference. As a result, the support element in the fully manufactured state of the body, in particular the fully manufactured state of the passenger car, has an open area in which the insert is arranged without overlap relative to the support element, and the bonding seam directly adjoins the open area in the circumferential direction of the side sill extending around the longitudinal extension direction of the side sill. As already described for the first aspect of the invention, the bonding seam is thus particularly well accessible to heat or heated air, so that the bonding seam can be cured simply and completely. The advantages and advantageous configurations of the first aspect of the invention can be regarded as advantages and advantageous configurations of the second aspect of the invention, and vice versa.

[0014] A third aspect of the invention relates to a passenger car, also referred to as a vehicle, having a body, in particular, according to the second aspect of the invention. In the third aspect of the invention, the body has at least one side sill, which has a support element made of steel and at least one insert made of light metal. The insert is directly bonded to the support element to form at least one bonding seam and is (in particular only) partially surrounded by the support element on the outer circumference, whereby the support element in the fully manufactured state of the passenger car has an open area in which the insert is arranged without overlapping relative to the support element. In this case, the bonding seam directly adjoins the open area in a circumferential direction of the side sill extending around the longitudinal extension direction of the side sill. The advantages and advantageous configurations of the first and second aspects of the invention can be regarded as advantages and advantageous configurations of the third aspect of the invention, and vice versa.

[0015] A fourth aspect of the invention relates to a method for producing a side sill for a body of a passenger car, the body being in particular designed as a self-supporting body. The body is therefore also referred to as a passenger car body. In the method, a structural unit is provided, which has a first support part of a support element of the side sill made of steel and an insert made of light metal, the insert being directly bonded to the first support part to form at least one bond seam and being (in particular only) partially surrounded by the first support part on the circumferential side.

[0016] In this method, the structural unit is connected to the second support made of steel of the support element only after the adhesive seam has completely hardened, thereby, for example, assembling the supports and thereby, for example, forming a particularly closed hollow cross section, for example, in which the adhesive seam is arranged or arranged. The method according to the invention makes it possible, for example, for the structural unit to be manufactured by a supplier, so that, for example, the adhesive seam can be hardened, in particular completely hardened, at the supplier, that is, in a method for manufacturing the structural unit performed by the supplier. The supplier, for example, provides the manufactured structural unit to a manufacturer, who is also referred to as the original equipment manufacturer, original manufacturer or OEM (original equipment manufacturer) and who is, for example, a different manufacturer or a different enterprise from the supplier. The manufacturer (OEM) can then, for example, provide the structural unit and connect it to the second support only after the adhesive seam has completely hardened. It can therefore be seen that the manufacturing of the structural unit can be carried out by the supplier, while the connection of the structural unit to the second support element can be carried out by the manufacturer (OEM), whereby the side sill can be manufactured advantageously, particularly in a time-saving and cost-effective manner. Furthermore, the side sill can be manufactured particularly time-saving and cost-effectively by the manufacturer (OEM), in particular, since the adhesive seam has already hardened and no curing of the adhesive seam has to be (anymore) performed at the manufacturer (OEM). Due to the (already) complete hardening of the adhesive seam, the insert is particularly firmly connected to the first support element, whereby the support element is advantageously reinforced by the insert. Advantages and advantageous embodiments of the first, second and third aspects of the invention can be regarded as advantages and advantageous embodiments of the fourth aspect of the invention, and vice versa.

[0017] It is conceivable that by assembling the support parts so that the support parts form a back cross section, at least one longitudinal region of the insert is completely surrounded by the support element in a circumferential direction of the side sill extending around the longitudinal extension direction of the side sill, so that in particular the adhesive seam is in particular completely overlapped or covered by the support element, in particular when viewed from the outside.

[0018] Furthermore, it is preferably provided that, by virtue of the fact that the insert is only partially surrounded by the first support on the circumferential side, the structural unit has, before its connection to the second support, one or the aforementioned open area, in which the insert is arranged without overlap relative to the support element, wherein the adhesive seam directly adjoins the open area of ​​the structural unit in a circumferential direction of the side sill of the structural unit extending around the longitudinal extension direction of the side sill. As a result, in particular before the structural unit is connected to the second support element, the adhesive seam can be particularly advantageously hardened, in particular at the supplier and / or in the manner described above with respect to the side sill according to the invention. In order to be able to manufacture the side sill particularly advantageously and particularly cost-effectively, it is provided in one embodiment of the invention that the structural unit is connected to the second support by riveting the insert directly to the second support. Alternatively or additionally, the structural unit is connected to the second support, for example, by welding the first support directly to the second support, in particular by spot welding. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following describes further details of the present invention by means of preferred embodiments with the aid of the accompanying drawings. In this regard, in the accompanying drawings:

[0020] Figure 1 A schematic cross-sectional view showing a first embodiment of a side sill of a self-supporting body of a passenger car;

[0021] Figure 2 a schematic cross-sectional view showing a second embodiment of a side sill; and

[0022] Figure 3 A schematic cross-sectional view of a third embodiment of a side sill is shown. DETAILED DESCRIPTION

[0023] In the figures, identical or functionally identical elements are provided with the same reference symbols.

[0024] Figure 1 A schematic cross-sectional view of a first embodiment of a side sill 1 of a self-supporting body 2 of a passenger car (also referred to as a vehicle) is shown. The self-supporting body 2 (also referred to as a body in white) comprises two side sills spaced apart from one another in the transverse direction of the vehicle, namely the side sill 1 as a first of the side sills and a second side sill not visible in the drawing. Furthermore, the body 2 comprises a main floor panel 3 (also referred to as floor panel for short), by which the interior of the body (also referred to as cabin or passenger compartment) and therefore the interior of the passenger car is defined in the vehicle height direction downwards. The floor panel extends in the vehicle transverse direction between the side sills. In the vehicle transverse direction the floor panel extends in the vehicle transverse direction between the side sills. Figure 1 The longitudinal direction of the vehicle is indicated by a double arrow 4, while the longitudinal direction of the vehicle is indicated by a double arrow 5 and is perpendicular to Figure 1 Furthermore, the vehicle height direction is indicated by a double arrow 6.

[0025] The side sill 1 has a longitudinal extension direction which extends in the longitudinal direction of the vehicle, i.e. parallel to the longitudinal direction of the vehicle. The side sill 1 extends at least substantially longitudinally along the longitudinal extension direction. The side sill 1 comprises a carrier element 7 made of steel. This means that the carrier element 7 can be made of exactly one, i.e. a single, steel, or the carrier element 7 can be made of a plurality of steels that are different from one another. Furthermore, the side sill 1 comprises an insert 8 (also referred to as insert for short), which is made of light metal, i.e. a light metal alloy. Figure 1 In the first embodiment shown in FIG. 1 , the insert 8 is made of aluminum, ie, an aluminum alloy. Furthermore, the insert 8 is designed as an extruded profile. Figure 1 It can be seen that the insert 8, in particular in its interior, has a plurality of cavities 23 which are separated from one another by intermediate walls 10 of the insert 8. Furthermore, the insert 8 is of one-piece construction, i.e. it is composed of a single workpiece. In contrast, the support element 7, as will be described in more detail below, is of multi-piece construction, i.e. it is formed, in particular, by a plurality of components which are constructed separately from one another and are connected to one another. The insert 8, which is currently constructed as an aluminum extruded profile, is directly bonded to the support element 7, which is constructed as a steel component, to form at least two or exactly two bonding seams 9 which are spaced apart from one another. This means that the bonding seams 9 are formed by means of an adhesive, in particular by the same adhesive, wherein the insert 8 is directly bonded to the support element 7 by means of the adhesive and thus by means of corresponding bonding seams 9. Furthermore, by Figure 1 It can be seen that the insert part 8 is only partially surrounded by the carrier element 7 on the outer circumference, so that the carrier element 7 now extends only partially around the insert part 8 in the circumferential direction of the side sill 1 and thus in the circumferential direction of the carrier element 7 and the insert part 8 extending around the longitudinal extension direction of the side sill 1. Figure 1 Indicated by the double arrow 11. Since the insert 8 is only partially surrounded by the carrier element 7 in the circumferential direction of the side sill 1 extending around the longitudinal extension direction of the side sill 1, the carrier element 7 is located between the side sill 1, the body 2 and the passenger car. Figure 1 In the fully manufactured state shown in , there is generally an open area 12 in which the insert part 8 is generally not overlapped by the carrier element 7 in the direction outwards, i.e. in the direction towards the surroundings 25 of the vehicle body 2. This means that in the open area 12, the insert part 8 is arranged without overlap relative to the carrier element 7. Here, the corresponding adhesive seam 9 directly adjoins the open area 12 in a circumferential direction of the side sill 1 extending around the longitudinal extension direction of the side sill 1. As a result, heat can be transferred particularly well from the air surrounding the side sill 1 to the corresponding adhesive seam 9, i.e. to the corresponding adhesive forming the corresponding adhesive seam 9, so that, for example, in the method for producing the side sill 1, an initially liquid adhesive can advantageously and in particular completely harden. As from Figure 1 As can be seen in the figure, the aforementioned components of the carrier element 7 are the supports 13, 14 and 15, which are designed separately from one another and are connected to one another. For example, the supports 14 and 15 are welded to one another, in particular directly welded, in particular by spot welding, so that, for example, the supports 14 and 15 are welded to one another, in particular directly, and are thus connected to one another to form at least one spot weld seam 16. In addition, in the first embodiment, it is provided that the insert part 8 is directly riveted to the support part 14 by means of at least one rivet 17, wherein, for example, the rivet 17 penetrates one of the adhesive seams 9. In addition, in the first embodiment, it is provided that the insert part 8 is directly riveted to the support part 13 by means of at least one rivet 18, wherein, for example, the rivet 18 penetrates another adhesive seam 9. A further structural element 19 is also provided, which is designed separately from the insert part 8 and separately from the supports 13, 14 and 15, and which can be designed, for example, as a paneling element and / or as an outer part of a side frame, in particular of the vehicle body 2. The component 19 can be a component of the carrier element 7, wherein, for example, the component 19 can be in particular directly joined to the support part 13. Furthermore, it is conceivable that the structural element 19 does not belong to the carrier element 7 and is joined, i.e. connected, to the carrier element 7, wherein the component 19 can, for example, be connected directly to the support 13. In this case, the insert 8 is also not overlapped by the structural element 19 in the open area 12, so that heat can be transferred from the aforementioned air to the adhesive in a particularly advantageous manner to cure the adhesive.

[0026] It is very preferably provided that in the fully manufactured state of the passenger car, the insert part 8 as a whole is not overlapped by any component of the body 2 or any component of the passenger car as a whole, in particular towards the outside and thus towards the surroundings 25. This allows the side sill 1 to be manufactured particularly simply and cost-effectively, since the adhesive and thus the corresponding adhesive seam 9 can be cured completely in a time-saving manner. This ensures a particularly strong connection between the insert part 8 and the carrier element 7. Figure 1 It can be seen that the support 13 of the support element 7, in particular the support element 7, is at least partially overlapped by the structural element 19 toward the outside, that is, toward the surroundings 25, and is thus covered. Thus, for example, the component 19 forms at least a part of the outer skin of the vehicle body 2 or the passenger car, which can be visually and tactilely perceived by people who are in the surroundings 25.

[0027] In order to be able to cure the adhesive and thus the adhesive seam 9 advantageously and completely, it is provided, for example, that the open area 12 extends over an angular range of at least 30°, in particular at least 45°, in the circumferential direction of the side sill 1. In a first embodiment, the angular range is at least or exactly 90°.

[0028] Figure 2A schematic cross-sectional view of a second embodiment of a side sill 1 is shown. In the second embodiment, the support element 7 comprises bearings 13, 14 and 15 and additional bearings 20 and 21, wherein the bearings 13, 14, 15, 20 and 21 of the support element 7 are designed separately from one another and are in particular directly connected to one another. In the second embodiment, a component 19 is provided, which can be a component of the support element 7 and is therefore a further bearing of the support element 7, or the component 19 is not a component of the support element 7. The component 19 can, for example, be directly connected to the bearing 13. It is also conceivable that the component 19 is a component of the side sill 1, or that the component 19 is not a component of the side sill 1 and is in particular directly engaged, i.e. connected, to the side sill 1, in particular to the bearing 13 and very particularly to the support element 7. With the aid of Figure 2 A method for producing a side sill 1 is described. In the method, a structural unit 22 is provided, which has support parts 13 and 21 of a support element 7 of the side sill 1, which are made of steel, and an insert part 8. The insert part 8 is directly bonded to the support element 7 to form a bonding seam 9, in this case in such a way that the support part is directly bonded to the support part 21 to form a first of the bonding seams 9 and directly bonded to the support part 13 to form a second bonding seam 9. Furthermore, the support parts 13 and 21 are directly welded to one another, in particular by spot welding, so that, for example, at least one spot weld seam 24 is formed.

[0029] The supports 13 and 21, each directly bonded to the insert part 8, form a support unit, by which the insert part 8 is only partially surrounded in the circumferential direction of the side sill 1 and thus in the circumferential direction of the insert part 8 and the structural unit 22 extending around the longitudinal extension direction of the side sill 1. As a result, the structural unit 22 itself (i.e. considered alone) has an open area 12, in which the insert part 8 is arranged without overlap relative to the support unit, i.e. viewed outwardly and thus towards the surroundings 25, it is not overlapped by the support unit. As a result, for example at the supplier where the structural unit 22 is manufactured, heat can be transferred particularly well from the air surrounding the structural unit 22 (e.g. in an oven for curing the adhesive bond seam 9), whereby the adhesive bond seam 9 can be cured advantageously and in particular completely.

[0030] Only after the adhesive seam 9 between the respective support part 13, 21 and the insert part 8 has completely hardened, the structural unit 22 is connected to the support parts 14 and 20, in particular directly, by virtue of the support part 21 being directly welded to the support part 20 and the support part 14 being directly welded to the support part 15. In this case, the support part 14 is directly welded to the support part 15, in particular by spot welding to form a spot weld seam 16, and the support part 21 is directly welded to the support part 20, in particular by spot welding to form a spot weld seam 26. Furthermore, the support part 14 is directly welded to the support part 20, in particular by spot welding to form a spot weld seam 27. Furthermore, in the second embodiment, it is provided that the insert part 8 is directly riveted to the support part 14, in particular by means of at least one rivet 17. Alternatively or additionally, it is possible that the insert part 8 is screwed directly to the support part 14, in particular by means of at least one screw, for example a flow drill screw. Furthermore, it is possible for the insert part 8 to be mechanically connected directly to the carrier part 14 , namely by means of at least one additional element, which may be, for example, a rivet 17 or the aforementioned screw.

[0031] For example, the component 19 is in particular directly connected, in particular welded, to the support 14. Alternatively or additionally, the component 19 can in particular be directly connected, in particular welded, to the support 13. Furthermore, in the second embodiment, it is provided that, for example, the insert 8 is directly riveted to the support 21 by means of a rivet 28, wherein, for example, the rivet 28 penetrates a first of the adhesive seams 9 and / or the rivet 18 penetrates a second of the adhesive seams 9.

[0032] at last, Figure 3 A schematic cross-sectional view of a third embodiment of a side sill 1 is shown. The third embodiment of the side sill 1 is produced, for example, by the method according to the second embodiment. In the third embodiment, the support part 21 is riveted directly to the insert part 8 by means of rivets 28. The structural unit 22 comprises the insert part 8 and the support parts 13 and 21, wherein, for example, Figure 3 The adhesive seam 9 on the middle right directly adjoins the open area 12 of the structural unit 22 in the circumferential direction of the side sill 1. As a result, heat can be transferred particularly well from the air to the Figure 3 The adhesive seam 9 on the right side of the middle Figure 3 The adhesive seam 9 on the middle right can be cured advantageously and completely. Figure 3After the adhesive seam 9 on the center right has hardened, the structural unit 22 is connected to the support part 14, in particular directly, for example by riveting the insert part 8 directly to the support part 14 by means of the rivet 17. In addition, for example, the support part 15 is welded directly to the support part 15, in particular by spot welding, and the spot weld seam 16 is formed in this process. It is also conceivable that the support part 21 is directly bonded or bonded to the support part 21 by means of the adhesive seam 29, that is, by forming the adhesive seam 29. In this case, the adhesive seam 29 is formed by the above-mentioned adhesive, by means of which the support part 21 is directly bonded to the insert part 8. In this case, the rivet 28 penetrates the adhesive seam 29, for example.

[0033] In a second embodiment, the structural unit 22 is connected to the support 20, in particular directly, for example, by the support 21, in particular directly connected to the support 20, in particular welded, the support 21 and 20 form or define, for example, a closed or open hollow cross section 30, in which the hollow cross section is arranged or arranged. Figure 2 In addition, since, for example, a structural element 19 belonging to the side sill 1, in particular to the support element 7, is connected to the support element 14 and / or to the support element 14, the structural element 19 and the support element 14 define, for example, a second, in particular open or closed, hollow cross section 31 in which the adhesive seam 9 is arranged or arranged. Figure 2 In the third embodiment, the structural element 19 is directly connected, in particular welded, to the support 13 and / or the support 14, for example the structural element 19 and the support 14 define a hollow cross section 30 in which the adhesive seam 9 is arranged or arranged in the hollow cross section. Figure 3 Adhesive seam 9 on the middle right. Adhesive seam 29 can be cured advantageously, for example, because it is very accessible to heat or the aforementioned air and thus to heat transfer from the air to adhesive seam 29 .
