Description

TECHNICAL FIELD

[0001] The present application relates to a fixing arrangement of a supply rail on a motor vehicle body and to a method for producing a fixing arrangement of a motor vehicle body. BACKGROUND

[0002] DE 10 2017 203 862 B3 discloses a heat source which can be an electrical or electronic device, an electric motor or a power electronics of an electric or hybrid vehicle. The heat source has a heat-emitting body which in turn has a spherical cap-shaped recess in which a ball is arranged completely or at least partially. The spherical cap-shaped recess abuts against the ball, thereby ensuring a good thermal conduction between the heat-emitting body and the ball. The ball is connected thermally to a heat-dissipating component which can be a metal sheet of the vehicle body. SUMMARY

[0003] It is an object of the present application to provide a fixing arrangement and a method for producing a fixing arrangement which enable a particularly reliable holding of a supply rail on a motor vehicle body.

[0004] According to the application, the object is solved by a fixing arrangement of a supply rail in a connection region and by a method for producing a fixing arrangement of a supply rail in a connection region.

[0005] The first aspect relates to a fixing arrangement of a supply rail in a connection region in which two body components of a motor vehicle are connected to one another. The connection region thus comprises connection sites at which the motor vehicle components contact one another. In the fixing arrangement, the supply rail is arranged resting on a first body component and is held on the first body component via a holding element. In particular, the supply rail, the first body component and the second body component are arranged one above the other in the connection region in a fixing direction. Furthermore, the first body component is held on the second body component by means of the holding element. This means that the supply rail is fixed not only on the first body component but also the first body component is connected to the second body component by means of the holding element. Thus, it is possible to connect the body components to one another and to fix the supply rail on the first body component in one work step by fixing the holding element on the second body component. As a result, the supply rail can be fixed particularly quickly on the first body component and the body components can be connected to one another particularly quickly.

[0006] It has proven advantageous in a further refinement of the application that a cover element is held on the holding element, which, together with the first body component, circumferentially surrounds the supply rail. This means that the cover element is fixed on the holding element, wherein the cover element at least partially covers the supply rail outwardly. In particular, the cover element covers the supply rail on the side of the supply rail which faces away from the first body component. Thus, the supply rail is circumferentially at least substantially completely surrounded by means of the cover element and the first body component, whereby the cover element and the first body component provide a housing for the supply rail. By means of the cover element and the first body component, the supply rail can be surrounded, for example, water-tightly, with respect to the surroundings. Furthermore, by means of the cover element, it is possible to prevent the supply rail from slipping or coming loose from the first body component. Thus, the supply rail can be held particularly reliably on the first body component. Furthermore, it is possible to protect the supply rail from contamination and damage by means of the cover element and the first body component, so that a particularly long service life of the supply rail can be achieved.

[0007] It has proven advantageous in a further configuration of the application that the holding element is held on the second body component via at least one screw connection or via at least one ball-shaped fixing element and / or the cover element is held on the holding element via at least one screw connection or via at least one ball-shaped fixing element. This means that the holding element can be screwed on the second body component and / or the cover element can be screwed on the holding element for a particularly reliable connection. Alternatively or additionally, the holding element can be snapped with the second body component and / or the cover element can be snapped with the holding element via the at least one ball-shaped fixing element. In particular, a connection can be established via the ball-shaped fixing element via a side recess in such a way that the ball-shaped fixing element is snapped. For example, the second body component can have the at least one ball-shaped fixing element and the holding element can have at least one receptacle which is matched to the respective ball-shaped fixing element, in which the ball-shaped fixing element can be snapped, whereby the holding element is snapped onto the ball-shaped fixing element on the second body component. Alternatively or additionally, the holding element can have at least one ball-shaped fixing element, which can be snapped into a respective receptacle of the cover element or the second body component, which is matched to the ball-shaped fixing element. A particularly reliable connection can be established particularly quickly between the holding element and the cover element and / or the second body component by means of the at least one ball-shaped fixing element. In particular, a plurality of ball-shaped fixing elements can be provided, via which the respective connections are established.

[0008] In another configuration of the application it is provided that the holding element is fixed to the second body component and is configured separately from the first body component. It is furthermore provided that the holding element partially surrounds the first body component, whereby the first body component is held on the second body component. This means that the holding element is not only configured separately from the first body component but also separately from the second body component. In order to connect the first body component to the second body component, the holding element is fixed to the second body component. It is furthermore provided that the holding element surrounds the first body component, for example in such a way that the holding element at least partially rests on the side of the first body component which faces away from the second body component. This means that the first body component rests on the second body component with a first side and on the holding element with a second side which is opposite the first side. By surrounding the first body component by means of the holding element, the first body component can be held particularly reliably on the second body component. Furthermore, the first body component can be particularly simply provided on the second body component via the holding element, whereby a connection between the first body component and the second body component can be established particularly simply.

[0009] In a further improvement of the application it is provided that the first body component has a cutout on its second side which faces away from the second body component, into which cutout the holding element is fitted. The holding element can be fixed relative to the first body component via the cutout, so that the first body component is held particularly reliably and positionally fixed on the second body component by means of the holding element. A sliding of the first body component relative to the second body component can thus be prevented in an advantageous manner. The relative position between the holding element and the first body component can be predefined via the cutout, whereby a particularly reliable positioning of the body components relative to one another can be achieved. In the case of the surrounding of the first body component by means of the holding element, the holding element is fitted into the cutout, whereby the holding element is oriented relative to the first body component. The cutout can thus achieve a particularly simple centring of the first body component relative to the holding element and thus relative to the second body component on which the holding element is held.

[0010] In another configuration of the application it is provided that the first body component has at least one guide element by means of which the holding element can be guided relative to the first body component. In particular, the first body component has a plurality of guide elements by means of which the holding element can be guided for centering of the first body component relative to the holding element and thus relative to the second body component on which the holding element is held, in order to center the first body component relative to the second body component. By means of the at least one guide element it can be ensured in the production of the fixing arrangement that the first body component is connected with the second body component in a predefined fixed position relative to the second body component. The at least one guide element extends, for example, parallel to a fixing direction which extends from a first side of the first body component to a second side of the body component. The fixing direction corresponds to the direction of action of a force of the holding element onto the second side of the first body component with which the first body component is pressed onto the second body component by means of the holding element.

[0011] In another configuration of the application it has proven advantageous that the first body component has an extending flange which laterally covers the supply rail resting on the first body component and by means of which the first body component is held on the second body component by means of the holding element. The extending flange has a second side of the first body component on which the holding element rests on the first body component. On the second side and thus on the flange the covering element can be fixed and / or the cutout can be provided. Alternatively or additionally, the flange can have the at least one guide element. In the fixing arrangement the flange can in particular be oriented perpendicular to an extension plane of the second body component which has the extension plane in the connection region, so that the flange encloses an angle of approximately 90° with the extension plane of the second body component. The holding element bridges over a free edge of the flange in order to hold the supply rail on the first body component. By means of the flange which laterally covers the supply rail and which is surrounded by the holding element in the fixing arrangement the supply rail can be protected laterally from damage or contamination on the one hand and can be positioned laterally on the other hand.

[0012] In another configuration of the application it has proven advantageous that the holding element is bonded with the first body component. This means that the holding element is held on the second body component via the threaded connection and / or the at least one spherical fixing element, which surrounds the first body component and is bonded with the first body component. Thus, the holding element is connected with the first body component via an adhesive, whereby a particularly reliable connection of the holding element with the first body component can be achieved.

[0013] In an alternative configuration of the application, the holding element is configured in one piece with the first body component. This means that the holding element is integrally formed on the first body component. Via the at least one threaded connection or the at least one ball-shaped fixing element, the holding element can be fixed on the second body component and thus the first body component can be fixed on the second body component via the holding element. The holding element is provided for holding the supply rail on the first body component, for example in such a way that it at least partially surrounds the supply rail. The one-piece configuration of the holding element with the first body component enables the fixed arrangement to be produced from particularly few components, whereby the fixed arrangement can be provided particularly quickly.

[0014] The application also relates to a method for producing a fixed arrangement of a supply rail in a connection region, in which two body components are connected to one another. In the method, it is provided that the supply rail is arranged on a first body component. Furthermore, it is provided that the first body component is arranged on a second body component. Furthermore, in the method, a holding element is fixed on the second body component, the supply rail is held on the first body component by means of the holding element and the first body component is held on the second body component by means of the holding element. By means of the holding element, the supply rail can be fixed on the first body component and the first body component can be fixed on the second body component simultaneously in one step, whereby the fixed arrangement can be provided particularly quickly and thus with a particularly short cycle time.

[0015] The advantages and advantageous further refinements of the fixed arrangement according to the application are to be regarded as the advantages and advantageous further refinements of the method according to the application and vice versa. For this reason, the further advantages and advantageous further refinements of the method according to the application are not described in more detail here.

[0024] Identical elements have identical reference numerals in the figures.

[0025] In Figure 1 and Figure 2 ​​​Fig. 1 shows a sectional view of a corresponding fixing arrangement 1 of a supply rail 2 in different embodiments on a motor vehicle body, in particular a motor vehicle body of a motor vehicle. Electrical energy and / or data can be transmitted or supplied to motor vehicle components of the motor vehicle by means of the supply rail 2. In particular, the supply rail 2 serves for transmitting electrical energy and / or data between two motor vehicle components. In order to be able to fix the supply rail in the motor vehicle particularly reliably, it is provided in the fixing arrangement 1 that the supply rail 2 is held on a first motor vehicle component 4 in a connection region 3. The connection region 3 comprises a contact point between the first motor vehicle component 4 and a second motor vehicle component 5. The first motor vehicle component 4 and the second motor vehicle component are thus in contact with or connected to each other in the connection region 3. The first motor vehicle component 4 and the second motor vehicle component 5 are each a motor vehicle component of the motor vehicle body.

[0026] In order to connect the motor vehicle components 4, 5 to each other and also to hold the supply rail 2 on the first motor vehicle component 4, a holding element 6 is provided. The holding element 6 is currently snapped onto a plurality of first fixing elements 7 which are integrally formed on the second motor vehicle component 5 and are configured at least substantially spherical. The holding element 6 has an arm 8 by means of which the first motor vehicle component 4 can be surrounded. The first motor vehicle component 4 can be fixed on the second motor vehicle component 5 by means of the arm 8. In order to fix the first motor vehicle component 4 on the second motor vehicle component 5, the first motor vehicle component 4 is placed onto the second motor vehicle component 5 with a first side 9. Subsequently, the arm 8 of the holding element 7 is applied to a second side 10 of the first motor vehicle component 4 which is opposite the first side 9. Thus, a pressure can be exerted onto the second side 10 of the first motor vehicle component 4 by means of the arm 8 in order to press the first motor vehicle component 4 with its second side 9 onto the second motor vehicle component 5. Thereby, the first motor vehicle component 4 is subjected to a fixing direction 11 which extends from the second side up to the first side 9. In order to hold the supply rail 2 on the first motor vehicle component 4 in the connection region 3, it is provided that the supply rail 2 is placed onto the first motor vehicle component 4 and that a force is exerted onto the supply rail by means of the arm 8 of the holding element 6 in order to press the supply rail 2 onto the first motor vehicle component 4 along the fixing direction 11 and thereby to fix the supply rail.

[0027] A cover element 12 is currently provided and fixed on the holding element 6. By means of the cover element 12, the supply rail 2 is covered on a side of the supply rail which is not covered with respect to the first motor vehicle component 4. This means that the cover element 12 together with the first motor vehicle component 4 at least circumferentially surrounds the supply rail 2. Via the cover element 12 and the first motor vehicle component 4, the supply rail 2 can be surrounded water-tightly with respect to the surroundings of the fixing arrangement 1. The cover element can be connected via a screw connection 13 as shown in Figure 1 or as shown in Figure 2The holding element 6 is connected or clipped to the holding element 6 via at least one second ball-shaped fixing element 14, as shown in. It can be provided here that the holding element 6 has the at least one second ball-shaped fixing element 14, which can be plugged into a receptacle of the cover element 12, or that the cover element 12 has the at least one second ball-shaped fixing element 14, which can be clipped into a corresponding receptacle of the holding element 6 in order to establish a connection between the cover element 12 and the holding element 6. Alternatively, the cover element 12 and the holding element 6 can be configured in one piece.

[0028] In Figure 3 , Figure 4 and Figure 5 the holding element 6 is shown in different views, wherein the cover element 12 or the connection options for connecting the holding element 6 with the cover element 12 are not shown in the views. Figures 3 to 5 The holding element 6 shown in can be free of connection means via which the holding element 6 can be connected with the cover element 12, or the holding element can have connection means not shown in, by means of which the holding element 6 can be connected with the cover element 12 via at least one screw connection 13 and / or at least one second ball-shaped fixing element 14. Figures 3 to 5

[0029] In Figures 3 to 6 the flange 15 of the first body component 4 is shown, which can be at least partially surrounded by the arm 8 of the holding element 6. The flange 15 projects at least substantially in the fixing direction 11 from the second body component 5 in the fixing arrangement 1. Here, the flange 15 can project in the fixing direction 11 beyond the lying surface 16 on which the supply rail 2 rests on the first body component 4. Figure 3 In the top view shown in, it can be seen that the arm 8 of the holding element 6 bridges the flange 15. It can further be seen that the arm 8 has a trapezoidal profile, which widens towards the side of the flange 15 on which the supply rail 2 is located. It can further be seen from Figure 2 that on the flange 15 two guide elements 17 are currently provided, which extend with their left-side extending direction parallel to the fixing direction 11. The first body component 4 can be centered with respect to the holding element 6 by means of the guide elements 17 in order to enable a particularly precise positioning of the first body component 4 with respect to the holding element 6. The guide elements 17 currently project obliquely from the flange 15 of the first body component 4 and match the obliquity of the side edges of the trapezoidal basic shape of the arm 8 with their oblique orientation.

[0030] In Figure 4 ​In the diagram, flange 15 is shown on the side of the flange facing the supply rail 2. It can be seen that flange 15 has a cutout 18 into which the arm 8 engages when it abuts against flange 15. Cutout 18 extends longitudinally from the side of flange 15 facing the supply rail 2 to the opposite side of flange 15 away from the supply rail 2. By means of the cutout 18, which tapers along a fixed direction 11, the first body component 4 and the retaining element 6 can be positioned relative to each other.

[0031] exist Figure 5 In the diagram, flange 15 is shown on the side opposite to supply rail 2. Retaining element 6 is shown in section here. In the cross-sectional view of retaining element 6, a first spherical retaining element 7 can be seen, via which retaining element 6 is connected to the second body component 5. To connect retaining element 6 to the second body component 5, retaining element 6 is snapped onto the first spherical retaining element 7. For this purpose, retaining element 6 has a corresponding receiving portion that matches the first spherical retaining element 7 and corresponds to the outer contour of the retaining element 7, within which the first spherical retaining element 7 can be accommodated when a connection is established between retaining element 6 and the second body component 5. Figure 5 It can also be seen how the retaining element 6 can be guided by the guiding element 17 to position the first body component 4 relative to the second body component 5. For a particularly secure connection between the first body component 4 and the retaining element 6, the first body component 4 can be bonded to the retaining element 6.

[0032] exist Figure 6 In the image, flange 15 is shown on the side of the flange facing away from supply rail 2. Cutout 18 and guide element 17 can be seen together here. The relative position to be adjusted between the first body member 4 and the retaining element 6 fixed on the second body member 5 can be pre-defined with particular precision by means of centering not only through cutout 18 but also through guide element 17.

[0033] To create the fixed arrangement structure 1, the first body component 4 and the second body component 5 are brought abutted against each other in the connection area 3. The supply rail 2 is then placed onto the placement area 16 of the first body component. The retaining element 6 is then fixed onto the second body component 5, wherein the arm 8 of the retaining element 6 spans the flange 15 of the first body component 4 and presses the supply rail 2 against the placement area 16 to hold the supply rail 2 on the first body component 4.

[0034] In an embodiment not shown in the figures, the holding element 6 can be configured in one piece with the first body component 4. For the production of the fixing arrangement 1, the supply rail 2 is thus placed onto the placement area 16 of the first body component 4, wherein the arms 8 of the holding element 6 press the supply rail 2 against the placement area 16 of the first body component 4. Furthermore, the holding element 6 is connected with the second body component 5 in order to fix the second body component 6 on the first body component 4 and thus to provide the fixing arrangement 1. Here, the second body component 5 can be screwed with the holding element 6 and / or be snapped with the holding element 6 via the at least one first spherical fixing element 7. By means of the holding element 6, the supply rail 2, which can be used for supplying energy and supplying data in a motor vehicle, can be integrated in the connection area 3 of the body components 4, 5.

[0035] The fixing arrangement 1 allows a cost-advantageous machine pre-production and / or robot pre-production of the integration of the supply rail 2 at the transition of the two body components 4, 5. In general, the present application shows how an integration of a supply rail 2 onto a body structure can be provided.
