Description

[0001] The present invention relates to a clip connection system for attaching a component to the body structure of a motor vehicle. The invention further relates to a motor vehicle with such a clip connection system. The invention also relates to a method for producing a clip connection using such a clip connection system.

[0002] A large number of connection systems for attaching a component, such as a modular power supply or control unit, a hydraulic-pneumatic hose, an electrical cable or the like, to a body structure, in particular a supporting structure, of a motor vehicle are already known from the prior art.

[0003] Depending on the weight and size of the component, several connection systems are used for attachment to the body structure, with assembly usually carried out by screwing to ensure a sufficiently strong and stable connection.

[0004] Such a mounting method using screws has significant disadvantages.

[0005] Firstly, screwing together a large number of screws requires an additional tool to turn them. During this process, individual screws can unintentionally fall from the installer's hand and be lost.

[0006] Furthermore, assembly often takes place in very confined spaces, making access extremely difficult or even impossible due to the additional tools required. This leads to further complex assembly steps and consequently increased assembly cycle times, which in turn results in high assembly costs.

[0007] Starting from this problem, the object of the present invention is to at least partially overcome the disadvantages described above. In particular, the object of the present invention is to create a cost-effective and reliable connection system for tool-free fastening of a component to the body structure of a motor vehicle. Furthermore, the object of the present invention is to create a cost-effective and improved motor vehicle and a simple method for producing a connection.

[0008] The foregoing problem is solved by a clip connection system having the features of claim 1, by a motor vehicle having the features of claim 12, and by a method having the features of claim 13.

[0009] Further features and details of the invention will become apparent from the dependent claims, the description, and the drawings. Features and details described in connection with the clip connection system naturally also apply in connection with the motor vehicle and the method according to the invention, and vice versa, so that the disclosure regarding the individual aspects of the invention always refers, or can refer, to each other.

[0010] According to the first aspect of the invention, the problem is solved by a clip connection system.

[0011] The clip connection system includes: - a clip element with a mounting surface and a locking and releasing mechanism, - a counter-clip element with a contact surface, - wherein the clip element and the counter-clip element can be clipped together along a connecting axis of the clip connection system, - a clipping locking element to ensure a permanent position of the clip element on the counter-clip element during clipping, - wherein the clipping locking element has a pressure stop surface and an installation verification surface, - wherein the clipping locking element within the clip element can be positioned in a pre-locking position by applying a minimum force to the pressure stop surface and in a final locking position by applying a closing force to the pressure stop surface, wherein the minimum force is greater than the closing force, - wherein the locking and release mechanism of the clip element blocks a displacement of the clipping locking element from the pre-lock position to the end-lock position when the clip element and the counter-clip element are not clipped together, in particular the contact surface of the clip element and the bearing surface of the counter-clip element from each other are spaced apart, and - wherein the locking and release mechanism of the clip element releases a displacement of the clipping locking element from the pre-lock position to the end-lock position when the clip element and the counter-clip element are clipped together, in particular when the contact surface of the clip element and the bearing surface of the counter-clip element are directly touching each other.

[0012] The core idea of ​​the present invention is therefore to do without an additional tool during assembly, in order to make assembly possible even in very confined spaces.

[0013] This can reduce assembly effort, in particular shorten assembly cycle times, which in turn can significantly reduce assembly costs.

[0014] The assembly is therefore not carried out by screwing, as required for process-reliable assembly according to the state of the art, but by a plug connection, in particular a clip connection. The clip element and the mating clip element can be clipped together along a plug axis of the clip connection system.

[0015] In other words, the clip connection system according to the invention enables simple, and in particular tool-free, assembly in very confined spaces.

[0016] According to the invention, it is particularly provided that the clip connection system includes a clipping locking element to ensure a permanent position of the clip element on the counter-clip element during clipping.

[0017] The fundamental aim of the invention is that the clip connection system fulfills all required holding forces even without the presence and activation of the clip locking element, in order to ensure a permanent fastening, in particular a clipping connection. However, the clip locking element according to the invention additionally prevents the clip element from unintentionally detaching from the mating clip element when clipped. Therefore, the clip locking element according to the invention should be understood solely as an employee / process aid, in particular to ensure that the clip element has been correctly installed.

[0018] This ensures a consistent installation of multiple connection systems and thus a consistent fastening path of the component as a whole to the body structure of the vehicle.

[0019] The clipping locking element according to the invention has a pressure stop surface and an installation verification surface and can be positioned within the clip element in a pre-locking position by applying a minimum force to the pressure stop surface and in a final locking position by applying a closing force to the pressure stop surface. The minimum force is greater than the closing force.

[0020] According to the invention, the locking and release mechanism of the clip element blocks a displacement of the clipping locking element from the pre-lock position to the end-lock position when the clip element and the counter-clip element are not clipped together, in particular when the contact surface of the clip element and the bearing surface of the counter-clip element are spaced apart from each other, wherein the locking and release mechanism of the clip element releases a displacement of the clipping locking element from the pre-lock position to the end-lock position when the clip element and the counter-clip element are clipped together, in particular when the contact surface of the clip element and the bearing surface of the counter-clip element are in direct contact with each other.

[0021] The blocking and release mechanism according to the invention provides the fitter, in contrast to the prior art, with certainty as to whether the assembly has been carried out correctly, in particular whether the clip element and the counter-clip element have been completely and correctly clipped together or not.

[0022] Preferably, the locking and release mechanism of the clip element comprises at least one locking element and / or one release element. Preferably, the locking and release mechanism of the clip element comprises multiple locking elements and / or release elements.

[0023] Preferably, the locking element is designed as a detent element and the release element as a spring element. The detent element can, in principle, have completely different shapes and, for example, be designed as a detent lug or a detent hook.

[0024] Preferably, when the clip locking element is positioned in the pre-locking position and / or the final locking position, haptic and / or acoustic and / or visual feedback can be provided by the clip locking element. This gives the installer additional assurance as to whether the assembly has been carried out correctly, in particular whether the clip element and the mating clip element have been correctly clipped together or not. This additional redundant safeguard is particularly advantageous when assembly takes place in very confined spaces and in dark environments, where the clip connection system is not easily accessible and / or visible to the installer.

[0025] Preferably, the installation verification surface of the clipping locking element has a machine-readable identification feature. This allows assembly to be carried out not only manually by the installer, but also semi-automatically or fully automatically by a machine, in particular an assembly robot. This further reduces assembly effort, especially shortens assembly cycle times, and consequently further reduces assembly costs.

[0026] Preferably, the identification feature is readable by a machine reader only when the clip element is clipped to the mating clip element. This provides the assembler or assembly robot with additional assurance as to whether the assembly was carried out correctly, in particular whether the clip element and the mating clip element have been correctly clipped together or not.

[0027] Preferably, the machine-readable identifier is a barcode, a data matrix code, or a QR code. This allows, for example, the assembly progress to be monitored and / or controlled in software.

[0028] Preferably, a holding device for receiving and / or guiding the component is provided on the clip element. It is also conceivable that the holding device for receiving and / or guiding the component is provided on the mating clip element. The holding device can, for example, have a plurality of U-shaped tabs and / or L-shaped hooks. The holding device can be integrated into the clip element or detachably attached to it. The holding device can be designed to be lockable and latched.

[0029] Preferably, the holding device has a rotating element that allows it to be rotated relative to the clip element. The rotatable design of the holding device relative to the clip element makes it easier, particularly in hard-to-reach installation spaces, to pick up the component within the holding device, to guide it through the device, or to flexibly align it in different directions.

[0030] Preferably, the clip connection system is designed as a bolt-clip connection system.

[0031] Preferably, in a further embodiment, the clip connection system is designed as a hole-clip connection system.

[0032] According to a second aspect of the present invention, a motor vehicle with a clip connection system according to the invention is proposed. The motor vehicle according to the second aspect of the invention offers all the advantages already described for the clip connection system according to the first aspect of the invention.

[0033] According to the third aspect of the present invention, a method for producing a clip connection using a clip connection system according to the invention is proposed. The method according to the third aspect of the invention offers all the advantages already described for the clip connection system according to the first aspect of the invention.

[0034] The method according to the invention comprises the following process steps: - Providing the clip element with the clipping locking element in a pre-assembled state, wherein the clipping locking element is secured by applying a minimum force F Min at the pressure stop surface 41 within the clip element 20 is positioned in a pre-locking position, wherein the clipping locking element in the pre-locking position is blocked from further displacement within the clip element by the blocking and release mechanism of the clip element, wherein when positioning the clipping locking element in the pre-locking position, haptic and / or acoustic and / or optical feedback is provided by the clipping locking element, - Clipping the clip element and the counter-clip element together along a plug-in axis, wherein in the clipped state the contact surface of the clip element and the bearing surface of the counter-clip element directly touch, wherein in the clipped state the locking and release mechanism of the clip element causes a displacement of the clipping locking element within the clip element from the pre-lock position to the end-lock position will be released - Applying a closing force to the pressure stop surface so that the locking element within the clip element is positioned from the pre-lock position to the final lock position, wherein the minimum force is greater than the closing force, wherein when positioning the locking element in the final lock position, the position of the clip element on the counter-clip element is permanently ensured by the locking element, wherein when positioning the locking element in the final lock position, haptic and / or acoustic and / or optical feedback is provided by the locking element, and - Reading a machine-readable identification feature on the installation verification surface of the clipping locking element using a machine reading device.

[0035] A clip connection system according to the invention is explained in more detail below with reference to the drawings. The drawings schematically show: Fig. 1 a clip connection system according to a first embodiment of the present invention, Fig. 2 a clip connection system according to a second embodiment of the present invention, Fig. 3 a motor vehicle with multiple clip connection systems according to an embodiment of the present invention and Fig. 4 A block diagram illustrating the process steps for producing a clip connection using a clip connection system according to an embodiment of the present invention.

[0036] Fig. Figure 1 shows a clip connection system 10 according to a first embodiment of the present invention.

[0037] As in the Fig. As can be clearly seen in Figure 1, the clip connection system 10 is designed as a bolt-clip connection system.

[0038] The clip connection system 10 essentially comprises a clip element 20, a counter-clip element 30 and a clipping locking element 40.

[0039] The clip element 20 has a contact surface 21 and a locking and releasing mechanism 25. The counter-clip element 30 has a bearing surface 31 and a bolt 35. The bolt 35 can preferably be designed as a threaded bolt.

[0040] The clip element 20 and the counter-clip element 30 can be concealed together along a plug-in axis S of the clip connection system 10, in particular clipped together.

[0041] The clip connection system 10 fulfills all required holding forces without the presence and actuation of the clipping locking element 40 in order to ensure a permanent fastening, in particular clipping.

[0042] However, the clipping locking element 40 according to the invention can additionally prevent the clip element 20 from unintentionally detaching from the counter-clip element 30 in the clipped state, so that the clipping locking element 40 according to the invention is to be understood merely as a pure employee / process support, in particular to ensure that the clip element 20 has been correctly mounted.

[0043] In the context of this application, "permanent securing of the position of the clip element 20 on the counter-clip element 30" means securing against unintentional loosening due to an operational disturbance such as vibration, thermal expansion, aging effect or other mechanical influence or similar.

[0044] The clipping locking element 40 has a pressure stop surface 41 and an installation verification surface 45.

[0045] The clipping locking element 40 is secured within the clip element 20 by applying a minimum force F Min at the pressure stop surface 41 into a pre-lock position V and by applying a closing force F Schließ can be positioned at the pressure stop surface 41 in an end detent position E, whereby the minimum force F Min is greater than the closing force F Schließ .

[0046] The clipping locking element 40 can be positioned within the clip element 20, in particular orthogonally to the plug axis S, from the pre-locking position V to the final locking position E.

[0047] The locking and release mechanism 25 of the clip element 20 blocks a displacement of the clipping locking element 40 from the pre-lock position V to the end-lock position E when the clip element 20 and the counter-clip element 30 are not clipped together.

[0048] The locking and release mechanism 25 of the clip element 20 releases a displacement of the clipping locking element 40 from the pre-lock position V to the final lock position E when the clip element 20 and the counter-clip element 30 are clipped together.

[0049] The clip element 20 and the counter-clip element 30 are not clipped together as long as the contact surface 21 of the clip element 20 and the bearing surface 31 of the counter-clip element 30 are spaced apart from each other.

[0050] In other words, the clip element 20 and the counter-clip element 30 are clipped together when the contact surface 21 of the clip element 20 and the bearing surface 31 of the counter-clip element 30 are in direct contact with each other.

[0051] The basic idea of ​​the invention is that, through the blocking and release mechanism 25 according to the invention, the assembler receives certainty as to whether the assembly has been carried out correctly, in particular whether the clip element 20 and the counter-clip element 30 have been correctly clipped together or not.

[0052] For this purpose, the locking and release mechanism 25 of the clip element 20 has several locking elements and release elements (not shown). The locking elements are designed as latching elements and the release elements as spring elements.

[0053] The locking elements and the spring elements are engaged in particular for blocking or releasing interaction and coupling with the clipping locking element 40.

[0054] It is conceivable that the detent elements and the spring elements additionally engage with the counter-clip element 30 itself or the bolt 35 of the counter-clip element 30 for blocking or releasing interaction and coupling. It is also conceivable that the detent elements and the release elements are not designed as separate elements, but as a single element with an elastically reversible property, in particular as a detent locking spring.

[0055] When the clipping locking element 40 is positioned in the pre-lock position V and / or in the final lock position E, haptic and / or acoustic and / or optical feedback can be provided by the clipping locking element 40.

[0056] In other words, feedback can only be output in the pre-lock position V or in the final lock position E or in both positions V, E by the clipping locking element 40.

[0057] The installation verification surface 45 of the clipping safety element 40 has a machine-readable identifier. The machine-readable identifier can be a barcode, a data matrix code, or a QR code.

[0058] Fig. Figure 2 shows a clip connection system 10 according to a second embodiment of the present invention.

[0059] As in the Fig. As can be clearly seen in Figure 2, the clip connection system 10 is designed as a hole-clip connection system.

[0060] The clip connection system 10 comprises, as in the first embodiment, a clip element 20, a counter-clip element 30 and a clipping locking element 40.

[0061] The clip element 20 has a contact surface 21 and a locking and releasing mechanism 25. The counter-clip element 30 has a bearing surface 31 and a through-opening 36, so that the clip element 20 and the counter-clip element 30 can be connected to each other along a plug-in axis S of the clip connection system 10, in particular by clipping them together.

[0062] The clipping locking element 40 is again within the clip element 20 by applying a minimum force F Min at the pressure stop surface 41 into a pre-lock position V and by applying a closing force F Schließ can be positioned at the pressure stop surface 41 in an end detent position E, whereby the minimum force F Min is greater than the closing force F Schließ .

[0063] According to the second embodiment, however, the clipping locking element 40 within the clip element 20 cannot be positioned orthogonally to the plug axis S from the pre-locking position V to the end-locking position E, but rather along the plug axis S.

[0064] The locking and release mechanism 25 of the clip element 20 also blocks the movement of the locking element 40 from the pre-lock position V to the end-lock position E when the clip element 20 and the counter-clip element 30 are not clipped together. Conversely, the locking and release mechanism 25 of the clip element 20 releases the movement of the locking element 40 from the pre-lock position V to the end-lock position E when the clip element 20 and the counter-clip element 30 are clipped together.

[0065] The clip element 20 and the counter-clip element 30 are not clipped together as long as the contact surface 21 of the clip element 20 and the bearing surface 31 of the counter-clip element 30 are spaced apart from each other. In other words, the clip element 20 and the counter-clip element 30 are clipped together when the contact surface 21 of the clip element 20 and the bearing surface 31 of the counter-clip element 30 are in direct contact with each other.

[0066] The locking and release mechanism 25 of the clip element 20 also has several locking and release elements (not shown), which are designed as detent elements and spring elements, respectively. The detent elements and spring elements also engage with the clipping locking element 40 for locking and releasing interaction and coupling.

[0067] According to the second embodiment, when the clipping locking element 40 is positioned in the pre-locking position V and / or in the final locking position E, haptic and / or acoustic and / or optical feedback can be provided by the clipping locking element 40.

[0068] The installation verification surface 45 of the clipping safety element 40 also has a machine-readable identifier. The machine-readable identifier can be a barcode, a data matrix code, or a QR code.

[0069] Fig. Figure 3 shows a motor vehicle 100 with several clip connection systems 10 according to the invention.

[0070] As in the Fig. As can be clearly seen in Figure 3, a component 110, in particular an electrical wiring harness, is attached to a body structure 120 of the motor vehicle 100 by several clip connection systems 10. The component 110 is specifically held by the respective retaining devices 15 of the clip elements 20, so that the multitude of clip connection systems 10 forms a kind of cable duct.

[0071] As in the Fig. As can be clearly seen in Figure 3, the installation position of the individual clip connection systems 10 does not vary from one another and therefore neither does the overall height of the component 110, so that a clear, in particular constant, fastening path of the component 110 to the body structure 120 of the motor vehicle 100 is ensured.

[0072] Fig. Figure 4 shows a block diagram to illustrate the process steps according to the invention.

[0073] According to the inventive method 200, in a first step S1 the clip element 20 with the clipping locking element 40 is provided in a pre-assembled state, wherein the clipping locking element 40 is secured by applying a minimum force F Min at the pressure stop surface 41 within the clip element 20 is positioned in a pre-locking position V.

[0074] The provision in a pre-assembled state preferably takes place before vehicle assembly, for example at the manufacturer of the clip element 20 or at the manufacturer of the wiring harness.

[0075] In other words, the clip element 20 is provided pre-assembled with the locking element 40, so that when assembly begins at the factory, the locking element 40 is already in the pre-locking position V. Therefore, the clip element 20 simply needs to be placed onto the mating clip element 30 and the locking element 40 actuated to confirm the insertion process, and in particular, the successful locking.

[0076] In this process, the clipping locking element 40 in the pre-lock position V is blocked by the blocking and release mechanism 25 of the clip element 20 from further displacement within the clip element 20.

[0077] When the clipping locking element 40 is positioned in the pre-lock position V, haptic and / or acoustic and / or optical feedback is provided by the clipping locking element 40.

[0078] In a second step S2, the clip element 20 and the counter-clip element 30 are clipped together along a connecting axis S.

[0079] In the clipped state, the contact surface 21 of the clip element 20 and the bearing surface 31 of the counter-clip element 30 are in direct contact.

[0080] In the clipped state, the blocking and release mechanism 25 of the clip element 20 releases a displacement of the clipping locking element 40 within the clip element 20 from the pre-lock position V to the final lock position E.

[0081] In a third step S3, a closing force F is applied. Schließ applied to the pressure stop surface 41, so that the clipping locking element 40 is positioned within the clip element 20 from the pre-lock position V to the final lock position E.

[0082] The minimum force F Min is greater than the closing force F Schließ .

[0083] When the locking element 40 is positioned in the end detent position E, the position of the clip element 20 on the counter-clip element 30 is permanently secured by the locking element 40, whereby when the locking element 40 is positioned in the end detent position E, haptic and / or acoustic and / or optical feedback is again provided by the locking element 40.

[0084] In a final fourth step S4, a machine-readable identification feature on the installation verification surface 45 of the clipping locking element 40 is read by a machine reader.

[0085] In principle, the simple and tool-free clipping of the clip element 20 to the counter-clip element 30 according to the invention, as well as the rotatable and releasable holding device 15, makes it possible that an assembly sequence is no longer necessarily determined by a given installation space, which in turn enables simplified assembly and fastening of the component 110 to the body structure 120 of the motor vehicle 100.

[0086] For example, the component 110 can first be picked up and fixed on the holding device 15 of the clip element 20, so that the component 110 is thereby indirectly attached to a body structure 120 of the motor vehicle 100.

[0087] Once the clip connection system 10, in particular the counter clip element 30, is attached to the body structure 120 of the motor vehicle 100, it is possible, due to the rotatable and detachable design of the retaining device 15, to align and fix it in a desired manner by rotating the retaining device 15 relative to the clip element 20 in a final assembly position only after the component 110 has been picked up on the body structure 120 of the motor vehicle 100.
