Description

Technical Field

[0001] The present invention relates to a component for wiring connection between the interior space of a vehicle and the motor compartment of the vehicle, a vehicle, and a method for establishing the wiring connection. Background Technology

[0002] In modern vehicles, it is often necessary to interconnect various (electronic) components. Since these components are often not located in a single location, but rather distributed in different locations throughout the vehicle, this results in a large number of wires being distributed throughout the vehicle.

[0003] To connect individual components to each other, the wiring must be guided laterally through the carrier. Here, the various areas within the carrier are partially separated from each other by frame components. In order to still enable the individual components to be connected to each other, appropriate openings need to be provided in the frame components or other separating structural elements through which the wiring can be guided.

[0004] Here, when assembling the carrier, the cost of threading the wires through the openings is considerable. Furthermore, the manual introduction of each wire prevents the carrier assembly from being automated further, as this step cannot be performed using a robot. Additionally, it is generally necessary to ensure that workers do not remain in the same area where robots are simultaneously operating.

[0005] The different configurations of the vehicle, especially whether it is a right-hand drive or left-hand drive vehicle, further complicate the assembly process. Typically, openings in the walls that separate vehicle components must also be adapted accordingly to allow wiring to be routed to individual components. This is particularly true for walls separating the vehicle's interior space from the motor bay. This results in increased costs in the design and manufacture of the walls used for these separations. Furthermore, the assembly of the vehicle is further complicated. Summary of the Invention

[0006] The objective of this invention is to at least partially eliminate the aforementioned disadvantages known from the prior art. In particular, the objective of this invention is to provide a component for wiring connections between the interior space of a vehicle and the motor compartment of the vehicle, a vehicle, and a method for establishing wiring connections, wherein assembly is simplified, costs are reduced, and the safety of assembly personnel is improved.

[0007] The aforementioned tasks are accomplished by components according to the invention, a vehicle according to the invention, and a method according to the invention. Further features and details of the invention are derived from the corresponding dependent claims, description, and drawings. Herein, the features and details described in conjunction with components according to the invention also apply to vehicles according to the invention and / or methods according to the invention, and vice versa, so that the disclosure of various aspects of the invention can always be cross-referenced.

[0008] According to a first aspect of the invention, an assembly is provided for wiring connections between the interior space of a vehicle and the motor compartment of the vehicle. This assembly has an intermediate wall disposed between the interior space of the vehicle and the motor compartment. Furthermore, the assembly has a wiring harness configured to electrically connect multiple onboard electrical system components of the vehicle to each other. The assembly also has a buttonhole connected to the wiring harness, wherein the intermediate wall has a central opening in the transverse direction of the vehicle, and the buttonhole is disposed in the opening.

[0009] In the context of this invention, a component should be understood as a collection of mechanically interconnected parts that can be extended by additional components.

[0010] A line connection is a connection, especially an electrical connection, that is achieved by at least one line, especially a cable.

[0011] In the context of this invention, the interior space of a vehicle should be understood as the passenger area or cargo area of ​​the vehicle. It may be configured such that a cockpit is located within the interior space of the vehicle, configured to control the vehicle and monitor its current state. Whether the interior space of the vehicle is substantially enclosed (e.g., in a passenger car) or open (e.g., in an open-top boat and convertible) is not critical. Similarly, it is not critical in the motor compartment whether it is open or tightly sealed relative to the environment. Therefore, in the context of this invention, the motor compartment is an area in which at least one motor of the vehicle can be arranged.

[0012] The vehicle can be any land vehicle, water vehicle, or air vehicle, but especially a motor vehicle, such as a passenger car.

[0013] An intermediate wall is a geometric shape that spatially separates two regions from each other. This separation can be partial, allowing openings to remain between the regions. Therefore, it is not necessary for the regions to be tightly separated by an intermediate wall. A single pillar, such as the A-pillar of a vehicle, can also be understood as an intermediate wall. For example, the A-pillar of a vehicle separates the interior space of the vehicle from its surrounding environment.

[0014] In the context of this invention, a wire harness should be understood as at least one line, but is generally understood as multiple lines connected in a bundle. Each line, especially a cable, may be configured to have multiple strands, which may also be individually sheathed. Similarly, the wire harness may be configured to have a sheath and / or cable ties. This achieves the advantages of protecting the wire harness from environmental influences and / or further simplifying the handling of the wire harness during assembly.

[0015] Alternatively, the wiring harness may be configured to have at least one longitudinal water seal that prevents moisture from being guided into the vehicle's interior space via the cable through a capillary effect.

[0016] The wiring harness can be configured to interconnect all onboard electrical system components within the vehicle's interior space and / or all onboard electrical system components in the motor bay. This achieves the advantage that only a single wiring harness is required to interconnect the onboard electrical system components, and therefore only one harness needs to be guided through the opening in the intermediate wall. This further simplifies assembly.

[0017] The harness can be configured as a single-piece harness. Here, "single-piece" means that all components are connected to a single bundle without interruption, much like in the human nervous system. In other words, a single-piece harness does not have connecting elements to link the individual bundle parts together. This achieves the advantage of further simplifying assembly, as there is no need to establish additional connections, which could each constitute a source of failure.

[0018] A buttonhole should be understood as a component configured to receive a wire harness. For this purpose, the buttonhole has an opening, particularly a circular opening, through which the wire harness extends.

[0019] The lateral direction of a vehicle should represent a direction, plane, or axis extending laterally to the vehicle's usual direction of travel. For example, in a passenger car, this corresponds to an axis that can be considered to extend between the two exterior rearview mirrors. In a right-handed coordinate system, the vehicle's height is located on the Z-axis, so the lateral direction corresponds to the Y-axis.

[0020] The central arrangement of the opening or buttonhole within the opening achieves the following advantages: the wiring harness can be centrally guided through the intermediate wall, thus allowing for the use of a single variant of the assembly, for example, for right-hand drive and left-hand drive vehicles. Those skilled in the art recognize that "central" does not necessarily mean precisely positioned in the center of the intermediate wall to the millimeter, but rather constructed sufficiently centrally so that if the design is changed from right-hand drive to left-hand drive or vice versa, no changes to the assembly are necessary when designing the remaining components, especially the cockpit. However, it can also be arranged such that "central" precisely indicates the central arrangement of the opening within the intermediate wall. This yields the advantage that symmetry can be particularly easily utilized for simplified arrangements in both right-hand drive and left-hand drive variants. The opening can have a diameter in the range of approximately 100 to 200 mm, preferably 120 to 140 mm, thereby allowing the wiring harness to be particularly easy to thread, especially if the harness is packaged in a pouch for assembly.

[0021] Within the scope of this invention, it is also conceivable that the intermediate wall has a sheet transverse support, wherein an opening is centrally arranged in the sheet transverse support in the transverse direction of the carrier. In other words, the sheet transverse support may include a notch as part of the intermediate wall, the notch being configured to receive a buttonhole.

[0022] In this context, the sheet transverse support member should be understood as a geometric shape implemented as a sheet supporting a carrier, particularly a windbreak sheet. To connect the sheet transverse support member to the sheet, a connecting surface can be provided, to which the sheet can be bonded.

[0023] The arrangement of eyelets in the sheet transverse support or sheet transverse support provides the following advantages: even when the motor is at least partially installed, the wiring harness can be passed through the opening and connected to the corresponding part in the motor compartment with particular ease.

[0024] The sheet material can be configured such that the opening in the transverse support is upward-facing. In other words, the sheet material can be configured such that the transverse support (especially in the bonding surface used to bond the sheets) has a notch. This achieves the following advantages: not only can the diameter of the actual opening be used for threading, but also a free space is created between the sheet material and, if possible, the motor cover, through which the wiring harness can be guided. This further simplifies assembly.

[0025] Furthermore, in the component according to the invention, the buttonhole can advantageously be configured such that the wire harness is guided in the guide section, and / or the buttonhole has a fixing section configured to secure the buttonhole to the intermediate wall. In other words, the component can have at least two regions that, on the one hand, are used to position the wire harness, and on the other hand, to position the buttonhole itself relative to the intermediate wall.

[0026] The fixing section and the guide section can be made of different materials. For example, the fixing section can be made of plastic or metal, which has higher strength than the guide section. This achieves the advantage that the buttonhole can be secured particularly reliably to the intermediate wall. Similarly, the guide section can be made of an elastic material, especially rubber, thereby achieving the advantage that the wire harness can be received particularly easily into the buttonhole.

[0027] The guide section and the fixing section can be configured to be manufactured together in a two-component injection molding process. This achieves the following advantages: simplified buttonhole manufacturing, and therefore, simplified component manufacturing overall.

[0028] Furthermore, in the assembly according to the invention, the buttonhole can advantageously be configured such that it has at least one ear with an opening for receiving a fastening device and is configured to abut against the intermediate wall. In other words, at least one connecting tab with a notch through which the fastening device can be guided, allowing the connecting tab to connect with the intermediate wall. This provides the advantage that the buttonhole can be secured particularly reliably to the intermediate wall. Furthermore, if a seal is provided at the buttonhole, this securing method ensures a particularly reliable fit within the seal.

[0029] In particular, it can be configured to have two (especially opposite) ears, thereby achieving a particularly secure fit of the buttonhole.

[0030] For example, threaded parts, rivets, or similar connecting devices can be used as fixing devices.

[0031] Within the scope of this invention, it is also conceivable that the buttonhole has a seal configured to seal the buttonhole relative to the intermediate wall. This achieves the advantage that moisture cannot seep from the motor compartment through the buttonhole into the interior space of the vehicle.

[0032] The seal can be configured as a sealing ring, which can be arranged, in particular, around the fixed section of the buttonhole. This achieves the following advantages: a particularly simple and reliable seal for the buttonhole. In particular, if the fixed section has an ear that connects to the intermediate wall, the seal or sealing ring can be pressed against the intermediate wall particularly effectively, thereby ensuring a particularly reliable seal.

[0033] Furthermore, the buttonhole can be configured to have a tab that abuts against the intermediate wall. In other words, the buttonhole can be configured to have a section that abuts against the intermediate wall. This provides the advantage that the buttonhole can be positioned at the intermediate wall in such a simplified manner. In particular, the tab and the fixed section of the buttonhole can be configured at approximately 90°. Furthermore, when the buttonhole is connected to the intermediate wall or a sheet transverse support, the tab engages into an upwardly open notch in the sheet transverse support. The tab can also include a groove into which the connecting surface of the sheet transverse support, particularly the sheet transverse support itself, engages when the buttonhole is connected to the intermediate wall. This achieves the advantage that the buttonhole can be positioned more easily at the intermediate wall and that the connection remains reliable.

[0034] Furthermore, in the assembly according to the invention, the tab can advantageously be configured such that it has a material insert made of the same material as the portion of the intermediate wall surrounding the tab. In particular, the tab can be configured such that it has a material insert made of the same material as the material of the connecting surface of the sheet lateral support. This provides the advantage that a single adhesive can be used when bonding the sheet to the sheet lateral support or the connecting surface of the sheet lateral support, eliminating the need for, for example, different adhesives for the sheet lateral support and the buttonhole, which may be composed of different materials. This further simplifies the assembly of the assembly.

[0035] In the components according to the invention, it is also conceivable that the buttonhole has at least one locking element configured to lock with the intermediate wall. This achieves a reliable fit of the buttonhole at the intermediate wall. The buttonhole can be configured to have multiple locking elements, particularly four locking elements. This further improves the fit of the buttonhole at the intermediate wall. The locking elements can be arranged at the crown, which is part of the fixing section of the buttonhole.

[0036] In particular, the combination with the tab at the buttonhole (which is arranged to rest against the intermediate wall) provides the following advantage: this buttonhole can be beak-type inserted into the intermediate wall. Here, the tab is first hooked into the intermediate wall, especially into the transverse support of the sheet, and then the buttonhole is pressed against the intermediate wall, followed by locking elements locking with the intermediate wall. This constitutes a particularly simple assembly method.

[0037] According to another aspect of the invention, a vehicle is provided having components according to the invention. The vehicle can be any land vehicle, water vehicle, or air vehicle, but is particularly a motor vehicle, such as a passenger car.

[0038] Therefore, the vehicle according to the invention has the same advantages as the components already described in detail according to the invention.

[0039] According to another aspect of the present invention, a method is provided for establishing a wiring connection between the interior space of a vehicle and the motor compartment of the vehicle. This method includes at least the following steps: - Position the component according to the invention in the cockpit. - Thread the wire harness through the opening in the middle wall. - Secure the buttonhole to the middle wall.

[0040] Therefore, the method according to the invention has the same advantages as those already described in detail with respect to the components and / or the vehicle according to the invention.

[0041] The cockpit is a structural unit used to control or monitor the vehicle's status. Passing through refers to inserting or threading a wiring harness through an opening in the intermediate wall.

[0042] Within the scope of this invention, it is further conceivable that at least one of the following steps is also provided: - Pack the vehicle's onboard electrical grid components in packaging bags. - Especially the use of robots to move the cockpit through the vehicle's door openings. - Especially the use of robots to secure the cockpit to the vehicle frame. - Connect the buttonhole piece to the middle wall. - Lock at least one locking element to the intermediate wall.

[0043] By packaging the airborne electrical grid components in a bag, the following advantages can be achieved: further simplification of assembly. During assembly, the bag is threaded through an opening provided for the wiring harness or buttonholes. In particular, it is advantageous that the buttonholes are not positioned at the opening, thus making the opening larger than the buttonholes themselves, especially when the opening is upward-facing, such as in the case of sheet-like transverse support members.

[0044] With the components according to the invention, cockpit relocation can be performed fully automatically, particularly by a robot. This achieves the advantages of further simplifying manufacturing and saving costs. By securing the cockpit to the vehicle frame, onboard electrical components or packaging bags can be easily removed from the cockpit and threaded through openings in the intermediate wall without the risk of the cockpit shifting.

[0045] When connecting the connector to the intermediate wall or the sheet transverse support, the connector can be configured such that it has a corresponding groove into which the connecting surface of the sheet transverse support, especially the sheet transverse support, engages. This ensures particularly simple assembly.

[0046] To allow the locking element of the buttonhole to engage with the intermediate wall, the buttonhole is pressed against the intermediate wall, and then the locking element engages with the intermediate wall. This constitutes a particularly simple assembly method.

[0047] In particular, the engagement between the intermediate wall and the slot of the connecting piece, and the engagement between the locking element and the locking of the intermediate wall, can be achieved through a beak-type access, which constitutes a particularly simple assembly method.

[0048] Other advantages, features, and details of the invention will become apparent from the following description, in which embodiments of the invention are described in detail with reference to the accompanying drawings. Hereinafter, features mentioned in the claims and in the specification may be important to the invention individually or in any combination. Indicatively: Figure 1 The diagram shows a view from the interior space of the vehicle toward the motor compartment, which includes a central wall.

Figure 6b The cockpit is shown being secured and screwed into the vehicle frame.

[0049] In the following description of some embodiments of the invention, the same reference numerals are used for the same technical features even in different embodiments. Detailed Implementation

[0050] Figure 1 Component 1 is shown for the wiring connection between the interior space 11 of the vehicle and the motor compartment 12 of the vehicle 10. (See from...) Figure 1 As can be seen from the diagram, component 1 has an intermediate wall 100 disposed between the interior space 11 of the vehicle and the motor compartment 12. Furthermore, component 1 has a wiring harness 200 disposed to electrically connect multiple onboard electrical network components of the vehicle 10 (shown only partially here) to each other. Also visible is that component 1 has a buttonhole 300 connected to the wiring harness 200, wherein the intermediate wall 100 has a first opening 130 at its center in the lateral direction 17 of the vehicle 10, and the buttonhole 300 is disposed in this opening.

[0051] exist Figure 1 In the middle, the intermediate wall 100 is constructed as a sheet transverse support member 110, wherein the first opening 130 is arranged in the center of the sheet transverse support member 110 along the transverse direction 17 of the carrier 10.

[0052] Here, the sheet transverse support 110 has a reinforcing element 120, which is implemented to improve the mechanical stability of the sheet transverse support 110. In particular, the reinforcing element 120 compensates for the weak points in the mechanical stability of the sheet transverse support 110 caused by the first opening 130. For example, the reinforcing element 120 may be configured to increase the material thickness in the sheet transverse support 110, configured to provide areas with special additives (such as glass fiber reinforcement or carbon fiber reinforcement), or as described here... Figure 1 It is constructed as shown in the diagram of the protrusion.

[0053] refer to Figure 2 (It also shows component 1), where the wiring harness 200 in its installed state can be seen. Here, it is clear that the wiring harness 200, in addition to the wiring 210, may also have a functional component 220. (As shown in...) Figure 1 As already shown in, in Figure 2 As can also be seen, the intermediate wall 100 is constructed as a sheet transverse support member 110, and has a first opening 130 at the center of the transverse direction 17 (indicated by the arrow) of the sheet transverse support member 110. Buttonholes 300 are arranged and fixed in the first opening 130. The wiring harness 200 is guided from the vehicle interior space 11 to the motor compartment 12.

[0054] exist Figure 3 The image shows a buttonhole 300 having a guide section 340 in which the wire harness 200 (not shown) is guided. The guide section 340 may have a resilient section 341. For example, this resilient section may be widened to allow the wire harness to pass through, thereby allowing the wire harness 200 to be easily connected to the buttonhole. When the resilient section 341 contracts, the individual lines 210 of the wire harness 200 are so strongly compressed against each other that a water-sealing section is no longer necessary at the wire harness 200.

[0055] In addition, Figure 3 A fixing section 320 can be seen at the buttonhole 300, which is configured to fix the buttonhole 300 to the intermediate wall 100. For example, the fixing can be achieved by shape fit, force fit and / or material fit.

[0056] exist Figure 3 As can be seen in the embodiment of the buttonhole 300 shown, the buttonhole 300 has at least one ear 360, which has a second opening 361 for receiving a fastening device and is configured to rest against the intermediate wall 100. Figure 3 In the middle section, two ears 360 are provided, each having a second opening 361 for receiving a fastening device. Furthermore, the two ears 360 are arranged opposite each other at the fastening section 320. This allows for particularly reliable fastening of the buttonhole 300 at the intermediate wall 100. Furthermore, in... Figure 3 As can be seen, the buttonhole 300 has a seal 350 configured to seal the buttonhole 300 relative to the intermediate wall 100. The seal 350 is configured here as a sealing ring that circumferentially surrounds the fixed section 320 or the flange 330 of the fixed section.

[0057] from Figure 3 As can also be seen, the buttonhole 300 has at least one locking element 331 configured to lock with the intermediate wall 100. In the illustrated embodiment, these locking elements are arranged on a flange 330, which is part of the fixing section 320.

[0058] exist Figure 4 The image shows a rear view from the interior space of the vehicle. The fixed section 320 and the resilient guide section 340 are also visible here. Similarly, the buttonhole 300 is shown to have a tab 310 configured to abut against the intermediate wall 100. The interaction between the tab 310 and the intermediate wall 100 can be seen below. Figure 5a and Figure 5b This is explained in the text.

[0059] exist Figure 5a The image shows a rear view (viewed from the interior space of the vehicle) of a buttonhole 300 installed in the intermediate wall 100, and... Figure 5b The image shows a front view (from the motor compartment) of a buttonhole 300 installed in the intermediate wall 100. As can be seen, particularly in the view on the right, the tab 310 of the buttonhole 300 engages with an edge 312 in the intermediate wall 100 or in the edge 111 of the sheet transverse support member of the intermediate wall. The edge 111 of the sheet transverse support member serves as a connecting surface for connecting the sheet transverse support member 110 to a sheet (not shown here). In other words, the tab 310 has a groove into which the connecting surface engages. Figure 5a and Figure 5b As can also be seen, the connecting surface has a notch at the location where the buttonhole 300 is installed into the intermediate wall 100. A material insert 311, composed of the same material as the portion of the intermediate wall 100 surrounding the insert 310, can be provided precisely at this notch on the connecting surface. This achieves the advantage that only one adhesive can be used when bonding the sheets, since only two different materials are being connected to each other.

[0060] Finally, Figure 6a and Figure 6b The image shows a portion of the vehicle 10, particularly the vehicle frame 13, which includes component 1.

[0061] The diagram illustrates a method according to the present invention for establishing a wiring connection between the interior space 11 of a vehicle and the motor compartment 12 of the vehicle 10. The method according to the present invention comprises the following steps: - Position component 1 in the cockpit 14, specifically in the packaging area 16 designated for this purpose. - Thread the wire harness 200 through the first opening 130 of the intermediate wall 100. - Secure buttonhole 300 to the middle wall 100.

[0062] Here, you can also set the following steps: - Pack the airborne electrical grid components of vehicle 10 in a packaging bag. - Move the cockpit 14 into the vehicle 10 through the door opening 15. - Secure the cockpit 14 to the vehicle frame 13. - Connect the tab 310 of the buttonhole 300 to the intermediate wall 100. - Lock at least one locking element 331 to the intermediate wall 100.

[0063] Here, the packaging bag can be secured in the packaging area 16 provided for this purpose on the cockpit of the vehicle 10. Due to the independence of the steering mechanism and the guidance of the wiring harness through the central opening in the intermediate wall, the movement of the cockpit 14 through the door opening 15 of the vehicle 10 can be fully automated, especially by a robot. This further simplifies assembly and reduces costs.

[0064] The foregoing description of the embodiments is merely an example to illustrate the invention. Of course, the various features of the embodiments can be freely combined with each other as long as it is technically reasonable and without departing from the scope of the invention.
