Description

Technical Field

[0001] The utility model relates to a plugging piece, which is used for sealingly closing an opening in at least one component of a motor vehicle. In addition, the utility model also relates to an arrangement structure of the plugging piece at the component of the motor vehicle. Background Art

[0002] Many possibilities are known for sealing openings in components, for example vehicle body components.

[0003] The first possible solution is to close the opening by means of a plastic plug. Such a plug is known, for example, from DE 10 2015 211 543 B4. The known plug is made of elastic plastic and has a tubular base body with an axial opening, at one end of which a bottom is arranged, and at the other end of which a flange is arranged, by means of which the plug can be supported at the edge region of the opening of the component with the opening. The disadvantage of such a plug is that, due to the tolerances at the openings, it is difficult to ensure that all openings are reliably closed. In addition, such a plug is problematic in terms of process reliability and proof of tightness.

[0004] Another possibility is to close such an opening with an adhesive pad. However, this requires extensive preparation work, such as degreasing the adhesive bond, and must also be applied manually. Furthermore, proof of the closure of the opening is only possible under certain conditions. Utility Model Content

[0005] The object of the invention is to provide a plug for closing an opening in at least one component of a motor vehicle, which plug can be assembled particularly reliably and whose correct assembly and sealing properties can be demonstrated particularly advantageously and are therefore reproducible.

[0006] According to the utility model, a plugging piece for sealingly closing an opening in at least one component of a motor vehicle is made of elastic plastic and has a tubular base body, which has an axial central opening, a bottom is arranged at one end of the base body, and a flange is arranged at the other end of the base body, by means of which the plugging piece can be supported at the edge area of ​​the opening of the component having the opening.

[0007] In order to provide a plugging piece that can be particularly reliably assembled and whose assembly and sealing performance that conforms to regulations are particularly advantageously proved and can therefore be reviewed, according to the utility model, the plugging piece is passed through a clamping element extending in a central opening, the clamping element is supported on the outside of the bottom and the flange with corresponding supporting parts, and the plugging piece can be loaded with an axial clamping force by means of the clamping element. By loading the plugging piece with an axial clamping force, the plugging piece deforms accordingly due to its elasticity and abuts against the edge area of ​​the opening in an advantageous manner, thereby sealing the opening. By applying an appropriate clamping force, the sealing of the opening can therefore be reliably ensured by means of the clamping element. Since the sealing of the opening is carried out by means of the clamping element and is therefore accompanied by the tightening / clamping of the clamping element, the measurement of this tightening / clamping can be used to finally prove the sealing. Therefore, for example, a threaded connection element or a rivet element can be used as a clamping element, and the force required for tightening the threaded element or for producing a riveting can be measured, from which it can be inferred whether the plugging piece has undergone sufficient deformation and therefore the opening is sealed in accordance with regulations.

[0008] In an advantageous design of the utility model, by loading the axial clamping force, the plugging piece is at least partially radially widened and / or axially shortened. Thus, the plugging piece is optimized to abut against the edge region of the component forming the opening, thereby realizing the desired reliable sealing of the opening.

[0009] In an advantageous embodiment of the invention, the clamping element comprises a screw connection element. As a result, a corresponding force can be generated in a simple, process-reliable and well-proven manner in order to deform the plug in the desired manner.

[0010] Alternatively to the screw connection element, the clamping element can also comprise a rivet element. With the aid of such a rivet element, the corresponding forces can also be generated in a simple, process-reliable and well-proven manner in order to deform the plug in a desired manner.

[0011] In addition, it is advantageous that the support portion on the side of the bottom of the plug is at least substantially adapted to the cross section of the opening. Thus, the clamping force can be input into the bottom of the plug particularly in a large format and uniformly, thereby realizing the axial shortening of the plug and the radial widening of the tubular matrix.

[0012] It is also advantageous if the clamping element is made of a metallic material, thereby making it possible to generate a sufficiently large clamping force applied to the plugging piece particularly reliably.

[0013] The advantages mentioned above in connection with the blocking element also apply to the arrangement according to the invention. This arrangement provides that openings are arranged in the body component and in the accumulator housing of the energy accumulator, wherein the blocking element passes through two openings. The openings serve here as so-called delimiting holes, by means of which the accumulator housing is arranged in a defined relative position on a workpiece carrier, by means of which the accumulator housing can be moved to the floor structure of the body of the motor vehicle for fastening within the scope of the final assembly of the vehicle.

[0014] It is also advantageous here that the tubular base body of the closing piece is adapted in cross section to the opening in the housing upper part of the reservoir housing, wherein the corresponding openings in the housing lower part and the body part are designed to be larger than the tubular base body of the closing piece. This makes it possible to particularly reliably prevent water from entering the reservoir housing from the outside on the one hand and the vehicle interior on the other hand.

[0015] Other features of the present invention are apparent from the drawings and the description of the drawings. The features and feature combinations mentioned above in the description and the features and feature combinations mentioned below in the description and / or shown individually in the drawings can be used not only in the respectively given combination, but also in other combinations or alone.

DETAILED DESCRIPTION

[0020] Figure 1 On the left side, a detailed bottom view of the rear part of the floor structure 1 of the body of a passenger vehicle is shown, from which in particular corresponding side sills 2 extending on the outside of the vehicle can be seen, which are connected to one another via a plurality of cross members, of which in particular a rear cross member 3 can be seen. In the region of this rear cross member 3, the floor structure 1 transitions into a rear vehicle structure 4, which has lateral rear longitudinal members, between which a rear floor 5 extends on the inside and on which corresponding rear wheel arches 6 are arranged on the outside.

[0021] The rear part of a reservoir housing 7 of an energy accumulator / high-voltage accumulator of an electric drive of a motor vehicle is arranged on the underside of the floor structure 1. In order to arrange the reservoir housing 7 in a defined relative position with respect to a workpiece carrier, by means of which the reservoir housing can be moved to the floor structure 1 of the body of the motor vehicle during the final assembly of the motor vehicle and can be fastened to the floor structure, a plurality of delimiting holes 8 are provided, in which the reservoir housing 7 is located. Figure 1 One of these openings 8 is shown in an enlarged detail view on the right in the figure, which is located in the connection region of the rear flange connection 9 of the reservoir housing 7 to the body component (rear cross member 3 ) arranged above.

[0022] The connection area is based on Figure 2a and Figure 2b or Figure 3a and Figure 3b In the other figures of the drawings, they are each shown in a schematic sectional view.

[0023] Here, from Figure 2a and Figure 2b In the drawing, firstly the rear flange connection 9 of the reservoir housing 7 can be seen, which has a flange of a housing lower part 10 and a flange of a housing upper part 11, which rest against one another in the region of the flange connection 9. In the present exemplary embodiment, the two flanges of the housing lower part 10 and the housing upper part 11 are connected to one another via a sealed adhesive connection.

[0024] Furthermore, a section through a body component in the form of a rear cross member 3 is shown, to which the reservoir housing 7 is fastened, in particular screwed, with a flange of the housing upper part 11. A seal 26, in the present case a butyl seal, is arranged forward or rearward between the housing upper part 11 and the cross member 3.

[0025] Combination Figure 1 The opening 8 described above passes through both the reservoir housing 7 with the housing lower part 10 and the housing upper part 11 and through the crossbar 3. In the region of the housing upper part 11 arranged between the upper crossbar 3 and the housing lower part 10, the opening 8 has a smaller, here approximately circular, cross section than in the region of the crossbar 3 and the housing lower part 10. In the region of the crossbar 3 and the housing lower part 10, the opening 8 has, for example, the same larger diameter, wherein the two diameters do not necessarily have to be of the same size.

[0026] The plug 12 is inserted into the opening 8 from below or from the outside for sealingly closing the opening 9 and is made of an elastic plastic / rubber material and has a tubular base body 13 with an axial central opening 14. The outer diameter of the base body 13 corresponds essentially to the diameter of the opening 8 in the region of the housing upper part 11, but can also be smaller.

[0027] A bottom 15 is arranged at the upper or inner end of the tubular base body 13, by which the opening 14 is cup-shapedly closed in the base body 13. Therefore, the bottom 15 is now designed to be disk-shaped and approximately flat. At the other, here lower or outer end, the base body 13 has an annularly surrounding flange 16, by means of which the plug 12 is supported at the edge region 17 of the opening 8 in the region of the component with the opening 8, in the present case in the region of the housing lower part 10. Therefore, the plug 12 is now inserted into the opening 8 from below or from the outside with the bottom 15 in front until the flange 16 rests on the outer side at the housing lower part 10.

[0028] In the present case, the closing element 12 is designed with a circular cross section at least substantially rotationally symmetrical about its central axis M. However, polygonal shapes of the closing element 1 or shapes (in particular of the base body 13 ) adapted to the elongated hole 8 are also conceivable.

[0029] The plug 12 comprises a clamping element 18 which extends in the central opening 14 and passes through the plug 12 over its axial length. Thus, a through opening 19 for the clamping element 18 is provided in the bottom 15 of the plug 12, which is currently smaller in diameter than the central opening 14.

[0030] In accordance with Figure 2a and Figure 2bIn the embodiment of the present invention, the clamping element 18 comprises a threaded connection element 20 in the form of a screw with a flat support part / head 21, which is flatly constructed and abuts against the equally flat bottom 15 of the plug 12 from above or from the outside. The shank 22 of the threaded connection element 20 is currently adapted to the through-opening 19 in terms of diameter or abuts tightly against the through-opening so that no water can enter through the through-opening. In addition, the threaded element 20 is currently vulcanized into the plug 12. The head / support part 21 is at least substantially adapted to the cross section of the opening 8 in the region of the housing upper part 11 or the bottom 15. The central opening 14 has a larger diameter than the shank 22 of the threaded connection element 20.

[0031] On the underside or outer side opposite the head 21, an outer thread is arranged on the shank 22, onto which a support part in the form of a threaded nut 23 is screwed. Between the nut 23 and the flange 16 of the plug 12, a washer 24 is arranged, which in the present case corresponds approximately in diameter to the diameter of the flange 16. Figure 2a An anti-rotation structure 25 can be provided between the washer 24 and the flange 16, which is shown again on the underside of the plug 14, for example, and is formed by an opening in which the material of the flange 16 is received. However, such an anti-rotation structure 25 is only optional and is usually not required to prevent a relative rotation of the nut 23 relative to the washer 24. The washer 24 can also be vulcanized into the plug 14.

[0032] In the present case, the clamping element 18 together with the closing piece 12 forms, in particular, a prefabricable structural unit which can be inserted into the opening 8 .

[0033] exist Figure 2a 1 and 2. The plugging member 12 with the clamping element 18 in the unclamped state is shown, that is to say, at most a light axial clamping force is applied to the plugging member 12 by means of the clamping element 18, so that the plugging member is at least substantially non-deformed. In this state, the plugging member 12 is also inserted into the opening 8 together with the clamping element 18.

[0034] and Figure 2a different, Figure 2b The plug 12 is shown when the clamping element 18 applies a correspondingly high axial clamping force by correspondingly tightening the threaded connection element 20 with the help of two supporting parts (head 21 and threaded connection nut 23) arranged on the outside of the plug 12, and this clamping force is introduced into the plug 12 via the bottom 15 or the flange 16.

[0035] Here, from Figure 2bIt can be seen that the plugging piece 12 is radially widened, especially in the region of the tubular base body 13, by being loaded with an axial clamping force by the clamping element 18, so that the plugging piece is tightly in contact with the edge region of the opening 8 in the region of the upper housing part 11, and is axially shortened in the region of the bottom 15 and the flange 16, so that the bottom 15 and the flange 16 are radially widened and axially pressed and are tightly in contact with the outer side of the upper housing part 11 or the lower housing part 10, respectively.

[0036] The ingress of water from the outside, indicated by arrow 28, is here particularly prevented by the flange 16, which bears against the housing lower part 10 in a pressed or tight manner. Furthermore, water cannot penetrate into the interior of the vehicle between the housing upper part 11 and the cross member 3, indicated by arrow 29, by the radially widened tubular base body 13, and finally water cannot pass into the cross member 3 according to arrow 30, by the bottom 15, which bears against the cross member 3 in a pressed or tight manner. Overall, multiple protection is now provided against the ingress of water from the outside.

[0037] The plug 12 can thus be clamped and deformed in a very reliable manner by the clamping element 18, so that water cannot enter. In addition, the plug 12 is thus held particularly reliably. Another advantage is that the torque, with which the nut 23 can be tightened to apply a corresponding clamping force, can be measured and documented very well to ensure a proper installation of the plug 12.

[0038] exist Figure 3a and Figure 3b Also shown in the unclamped state ( Figure 3a ) and clamped state ( Figure 3b ) has substantially the same function as the blocking member 12, so that only the blocking member 12 according to Figure 2a and Figure 2b The differences in the embodiments and in other respects the features and advantages should be regarded as being the same.

[0039] according to Figure 3a and Figure 3b The main difference of the embodiment of the present invention is that a rivet element 27 is provided as a clamping element 18, by means of which an axial clamping force is generated for loading and deforming the plug 12. At present, the rivet element 27 is for example Figure 3a A watertight blind rivet with a tip can be seen, with a support part / head 21 arranged on one side and a support part / rivet head 23 arranged on the other side, which can be shortened in length using a corresponding tool and can thus be clamped.
