Description

[0001] For design purposes, there is a trend toward making a vehicle's human-machine interfaces, such as switches, invisible at first glance by integrating them into interior trim panels. Such interior trim panels are typically formed by providing a support structure supporting a decorative layer, which is often laminated to the support structure during the manufacturing process.

[0002] When operating such human-machine interfaces, especially while driving the vehicle, so that operating the interface should not require diverting attention from the road to the interface, it is highly desirable to provide haptic feedback even in cases where activating the switch does not require mechanical movement, e.g., when controlled by capacitive sensing.

[0003] This can be achieved relatively easily by providing the carrier with a hole whose shape is adapted to complement the external shape of the electronic module. The carrier is then placed in a suitable laminating tool or provided with a mock-up of the electronic module to provide a flat surface onto which the decorative surface is laminated. After the lamination step, the carrier with the laminated decorative surface is removed from the laminating tool, the mock-up, if present, is removed, and the electronic module and / or its activation element are inserted into the hole and fixed in place such that haptic feedback, preferably through a slight movement of the electronic module and / or its activation element, is provided during the switching process.

[0004] Unfortunately, however, it turns out that this approach tends to cause markings that make the human-machine interfaces visible and are therefore undesirable.

[0005] Therefore, attempts have been made to achieve truly seamless integration by placing the electronics module behind a continuous substrate without any holes, i.e., on the opposite side of the substrate to that on which the decorated surface layer is located. While this approach works well to create truly invisible human-machine interfaces, particularly for human-machine interfaces that rely on sensing a capacitive effect from a user's finger to receive user commands, haptic feedback, if possible at all, is relatively weak. Detecting a fingerprint input in human-machine interfaces is quite difficult, and it turns out that under unfortunate circumstances, pressure exerted on the substrate surface above a first switch can also activate a second switch.

[0006] The problem addressed by the present invention is therefore to provide a method for manufacturing an interior trim part with a substantially invisible integrated human-machine interface that provides improved haptic feedback, and to provide such an interior trim part and a vehicle equipped with such a trim part. This problem is solved by a method having the features of claim 1, by an interior trim part having the features of claim 8, and by a vehicle having the features of claim 13. Advantageous embodiments of the invention are defined in the respective dependent claims.

[0007] The result of the method of the invention is an interior trim part with an integrated human-machine interface, wherein the interior trim part comprises a carrier, a decorative surface layer attached to the carrier (directly or indirectly via a connecting layer), and at least one electronic module that can be actuated by touching an activation area on the interior trim part.

[0008] The method is characterized in that it comprises a step of creating an at least partially decoupled portion of the carrier, which is located in the activation region of the carrier and is at least partially decoupled from the remaining part of the carrier, and wherein the at least partially decoupled portion of the carrier is and remains attached to the decorative layer. It should be noted that this step of creating the at least partially decoupled portion of the carrier can be performed as part of the manufacture / production of the carrier or after this manufacture / production at a later time.

[0009] Through this continued attachment between the at least partially decoupled portion of the carrier and the part of the decorative layer located in the activation region, this part of the decorative layer is supported throughout the entire manufacturing process. If the decorative layer is attached after the at least partially decoupled portion has been created, this part thereof is supported by the at least partially decoupled portion the entire time. If the decorative layer is attached before the at least partial decoupling is performed, the carrier body provides the support before this process, and the at least partially decoupled portion provides the support afterward.

[0010] The inventors have come to the surprising discovery that it is not the decoupling itself that leads to visible markings when using prior art methods for manufacturing interior trim parts with an integrated human-machine interface. Instead, decoupled areas of the substrate can be used in a process flow that ensures that the part of the decorative surface layer covering this at least partially decoupled section, i.e., the part located in the activation region, is continuously supported from the moment it is attached to the substrate.

[0011] In particular, a portion of the substrate is considered to be at least partially decoupled if a given force acting on it in the direction from the front of the substrate, i.e., the side facing the decorative layer, results in a greater displacement of this at least partially decoupled portion than the application of the same force in the same direction to another, untreated portion of the substrate. The inventors have discovered numerous ways of achieving this, which prove advantageous under various circumstances.

[0012] According to a preferred embodiment of the method, the step of creating an at least partially decoupled portion of the carrier, which is located in the activation region of the carrier and is at least partially decoupled from the remaining part of the carrier, is performed before the step of attaching the decorative surface layer to the carrier. This reduces the risk of damaging the decorative surface layer during the decoupling of the part of the carrier.

[0013] According to a further preferable embodiment, the method further comprises a step of completely decoupling the activation region from the remaining parts of the carrier, wherein the step of completely decoupling is carried out after the decorative surface layer has been attached to the carrier.

[0014] Complete decoupling means that a force applied to the completely decoupled section has no direct effect on the remaining section of the substrate. This is typically achieved when the edge of the completely decoupled section is formed by a cut extending through the entire depth of the substrate material, so that the completely decoupled section is essentially held in place by the decorative layer.

[0015] In other words, in a first step, a partial decoupling is performed, which still leaves some connections to the remaining part of the carrier, and then these connections are separated during the complete decoupling step.

[0016] This approach can be particularly useful in cases where precise positioning of the decoupled section is important and / or high demands are placed on the substrate material during the attachment of the decorative layer, e.g., high pressures.

[0017] According to a further embodiment of the method of the invention, the step of creating an at least partially decoupled portion includes the use of 2K injection molding during the manufacture of the carrier. Several approaches fall under this embodiment. First, using this technique, it is possible for the entire at least partially decoupled portion of the carrier to be formed from a different material than the rest of the carrier, which is preferably more elastic and therefore reacts in a haptically recognizable manner to a force exerted on it.

[0018] Alternatively, it is also possible to form only one boundary line that surrounds the at least partially decoupled section of the carrier and completely separates it from the surrounding parts of the carrier by a second, more elastic material. Accordingly, in this variant, a force exerted on the at least partially decoupled section of the carrier leads to a movement of this section and a deformation of the boundary line formed by the second material, which then provides an elastic restoring force and thus haptic feedback. The haptic feedback of the sensation of actual displacement can be enhanced by an active haptic feedback system that creates the sensation of pressing a mechanical button.

[0019] According to a further advantageous embodiment of the invention, the step of producing an at least partially decoupled portion of the carrier comprises a local cutting through the carrier, preferably in the direction from its front side, which faces the decorative layer, to its rear side, ie the side opposite the front side.

[0020] If the cutting is performed along the entire boundary line of the at least partially decoupled section to be formed, this can obviously lead to a complete decoupling, as described above, which provides the most direct tactile feedback but also exerts a certain tension on the decorative layer and is therefore not suitable for all types of decorative layers.

[0021] However, it is also possible to leave one or more local connections to the surrounding parts of the beam. In this configuration, it is also possible to create spring-like connections to the surrounding parts of the beam by appropriately designing cuts or slots that extend into the surrounding parts of the beam.

[0022] According to yet another advantageous embodiment of the method, the step of creating an at least partially decoupled section of the carrier includes a local reduction in the thickness of the carrier, in particular along the boundary line of the at least partially decoupled section. Particularly if the carrier material is not too rigid, this can open up the possibility of moving the at least partially decoupled section of the carrier relative to the remaining parts of the carrier.

[0023] Furthermore, it can also be advantageous if the step of creating an at least partially decoupled section of the carrier comprises providing a first section of the carrier having a hole in the region of the activation region, providing a second section of the carrier with a shape that complements the hole as a separate part, and coupling the first section of the carrier and the second section of the carrier. This can also be done in various variants. In a first variant of this procedure, a cover made of a different, preferably more elastic material than the first section of the carrier can be provided, wherein the cover covers the hole. Preferably, the cover is held in place by the decorative layer.

[0024] In a second variant of this approach, a portion of the electronic module's housing forms the second part of the carrier, which is arranged within the hole of the first part of the carrier. Unlike prior art methods that involve the use of a dummy while the decorative layer is attached to the carrier, this portion of the housing remains in place, and only the electronic module is installed at a later time.

[0025] The interior trim part with integrated human-machine interface according to this invention comprises a carrier, a decorative surface layer attached directly or indirectly, e.g., by lamination, to the carrier, and at least one electronic module that can be actuated by touching an activation area on the interior trim part, more specifically, on an outer surface of the interior trim part. According to the invention, the interior trim part with integrated human-machine interface comprises an at least partially decoupled portion of the carrier that, when the interior trim part is oriented with the activation area facing upwards, is located below the activation area, wherein the at least partially decoupled portion of the carrier is at least partially decoupled from the remaining part of the carrier.

[0026] This at least partial decoupling enables haptic feedback when the human-machine interface is activated, e.g. by pressing a finger on the activation area.

[0027] According to a preferred embodiment of the interior trim part, the at least partially decoupled section of the support consists of a different material than the parts of the support that surround the at least partially decoupled section of the support. This can be achieved, for example, by producing the support using 2K injection molding processes, but also by providing a two-part support. Preferably, the different material used is a material that is more elastic than the material of the surrounding parts of the support.

[0028] According to a further preferred embodiment of the interior trim part, the at least partially decoupled section of the carrier is separated from the parts of the carrier surrounding the at least partially decoupled section of the carrier by a layer of another, preferably elastic material. This can also be achieved by using 2K injection molding techniques.

[0029] According to yet another preferred embodiment of the interior trim part, the carrier comprises two parts, and the at least partially decoupled portion of the carrier is formed by a second part of the carrier, preferably a cover or an outer housing of the electronic module, the shape of which is adapted to complement a hole in a first part of the carrier. The cover is preferably made of a more elastic material than the first part of the carrier; the outer housing of the electronic module can be connected to the first part of the carrier by pins in a manner that allows it to slide on the pins in a direction perpendicular to the surface of the outer housing of the electronic module, together with elastic elements or springs that provide a restoring force that counteracts the pressure exerted upon touching the activation area of ​​the interior trim part, thus providing haptic feedback.

[0030] However, as previously mentioned, in any of the embodiments, an active haptic feedback system that creates the feeling of pressing a mechanical button may be used to achieve, or at least approximate, haptic feedback of the feeling of actual displacement.

[0031] Yet another advantageous embodiment of the interior trim part has an at least partially decoupled portion which is at least partially separated from the parts of the carrier surrounding the at least partially decoupled portion of the carrier by cuts or slits extending through the carrier material.

[0032] The motor vehicle according to the present invention is characterized by an interior trim part according to one of the embodiments described above.

[0033] Next, the invention will be explained in more detail with reference to figures that show specific embodiments by way of example. The figures show: Fig. 1a-f: Process steps of a first prior art process for producing an interior trim part with an integrated human-machine interface, Fig. 2: an interior trim part with an integrated human-machine interface, which is the result of carrying out a second prior art method for producing such an interior trim part, Fig. 3a-d: Processing steps of a first embodiment of the method of the invention, Fig. 4a: a first intermediate product obtained from a second embodiment of the process of the invention, Fig. 4b: a second intermediate product obtained from the second embodiment of the process of the invention, Fig. 5: an intermediate product obtained from a third embodiment of the process of the invention, Fig. 6: an intermediate product obtained from a fourth embodiment of the process of the invention, Fig. 7: an intermediate product obtained from a fifth embodiment of the process of the invention, Fig. 8a: a first variant of an intermediate product obtained from a sixth embodiment of the process of the invention, and Fig. 8b: a second variant of an intermediate product obtained from a sixth embodiment of the process of the invention.

[0034] As in Fig. 1a), according to the prior art, a support 10 is provided with a hole 11 whose shape is adapted to complement the external shape of the electronic module 12. This adaptation means that the top of the electronic module 12 can be inserted into the hole 11 to such an extent that the external surfaces of the support 10 and the electronic module 12 lie in the same plane and that, in this position, only a small gap exists between these parts.

[0035] As in Fig. 1b), the carrier 10 can then be placed in a suitable laminating tool 13 to create a flat surface on which the decorative surface layer 14 is attached by lamination, resulting in the Fig. 1d) shown intermediate state. Alternatively, according to a Fig. 1c), a dummy 12a of the electronic module 12 can be arranged in the hole 11 of the carrier 10 in order to provide a flat surface on which the decorative surface layer 14 is attached by lamination.

[0036] After the lamination step, the carrier 10 with the decorative surface layer 14 attached thereto is removed from the lamination tool 13 and / or the dummy 12a of the electronic module 12, if present, is removed. The corresponding arrangement of carrier 10 and decorative surface layer 14 is shown in Fig. 1e).

[0037] Finally, in order to obtain the interior trim part 1 with an integrated human-machine interface, the electronic module 12 and / or its activation element are inserted into the hole 11 and fixed in such a way that a haptic feedback, preferably by a slight movement of the electronic module 12 and / or its activation element, is provided during the switching process, as shown in Fig. 1f). In the Fig. In the example shown in Figure 1f), this is achieved by attaching the electronic module 12 with pins 15 in a manner that allows it to slide on the pins in a direction perpendicular to the laminated surface of the electronic module 12, along with elastic elements or springs 16 that provide a restoring force that counteracts the pressure exerted upon touching the activation area 1a of the interior trim part 1, thus providing haptic feedback. Unfortunately, the human-machine interface obtained in this way is not invisible, since there are markings on the A-side that can be recognized upon close inspection of the decorative surface layer 14.

[0038] Fig. Figure 2 shows an interior trim part 2 with a truly seamlessly integrated human-machine interface, which is the result of performing a second prior art method for manufacturing such an interior trim part. According to this second method, a carrier 20 is provided which has no hole and thus offers a flat front surface to which a decorative surface layer 24 can be attached, e.g., by gluing or laminating. After the gluing or lamination has been performed, the electronic module 22 can be attached using pins 25 and elastic elements or springs 26 in a similar manner as described above in connection with Fig. 1f described.

[0039] To enable at least some haptic feedback, the carrier 20 is thinner in the area of ​​the activation region 2a than outside the activation region. However, the haptic feedback that can be provided in this way is limited, and in situations where multiple human-machine interfaces are located in close proximity to one another, pressure applied to the carrier 20 in one activation region may inadvertently activate another human-machine interface.

[0040] Next, an embodiment of the method according to this invention, which is shown in the Fig. 3a to 3d. In the first step of the method, a carrier 100 having a hole 101, which is substantially identical to the carrier 10 of Fig. 1a is identical. In a subsequent step, the result of which is Fig. 3b, however, a completely (and thus also at least partially) decoupled section 110 is added in the activation region 3a, this section 110 being formed by an outer housing, into which the electronic module 140 is to be installed at a later stage of the process. The outer housing is movably fastened to a screw boss by screws 115 with an optional decoupling element and is therefore connected to the carrier 100 so that it can move against the force of elastic elements or springs 116 in the direction away from the upper surface of the carrier 100, i.e., the surface on which the decorative surface layer 130 is applied. This is already the final assembly of the outer housing, in contrast to the dummy 12a of Fig. 1c).

[0041] In a further processing step, the result of which is Fig. 3c), the decorative surface layer 130 is attached to the surface of the carrier 100, which contains the at least partially decoupled section 110, before the electronic module 140 is installed, resulting in the interior trim part 3 with integrated human-machine interface, which in Fig. 3d).

[0042] The Fig. 4a and Fig. 4b show a first and a second intermediate product produced in a second embodiment of the process of the invention. Fig. The first intermediate product shown in Figure 4a is the carrier 200 with an at least partially decoupled section 210, seen from below. Fig. 4a, the at least partially decoupled section 210 is separated and thus decoupled by a cut 250 through the carrier 200, which was made before the application of the decorative surface layer 230, starting from the front side of the carrier. As shown in the cross-sectional view of Fig. 4b, however, the back of the carrier has projections 251, and the depth of the cut is not so deep that it passes through the projections 251. This has the consequence that the decorative surface layer 230 is attached to the surface of the carrier 200 containing the at least partially decoupled portion 210, but the latter is still held in place by the projections 251. As shown in Fig. 4b, however, these projections 251 are then removed, resulting in a complete decoupling of the at least partially decoupled portion 210, which is now essentially held in place by the decorative surface layer 230 and can provide haptic feedback upon activation. In this example, the decoupled part is manufactured in the same process and with the same tool as the carrier 200. This avoids different behavior that would result in visible markings.

[0043] Fig. Figure 5 shows an intermediate product obtained from a second embodiment of the process of the invention. Fig. The first intermediate product shown in Figure 5 is the carrier 300 with an at least partially decoupled section 310, seen from below. As shown in Fig. 4a, the at least partially decoupled section 310 is separated by a cut 350 through the carrier 300 and thus decoupled. Also as in Fig. 4a, the decoupling is not complete, since the at least partially decoupled section 310 is connected to the surrounding part of the carrier 300 by meandering material strips 351, whereby a haptic feedback is possible, during which the at least partially decoupled section 310 remains in place. As in the embodiment of the Fig. 4a and Fig. 4b, the decoupled part is manufactured in the same process and tool as the carrier 300, thus avoiding different behavior that would result in visible markings.

[0044] Fig. Figure 6 shows an intermediate product obtained from a fourth embodiment of the method of the invention, namely a carrier 400 with an at least partially decoupled section 410 to which the decorative surface layer 430 has already been attached. The decoupling is achieved here by grooves 450 that extend from the back into the carrier 400 but do not penetrate it.

[0045] In the Fig. The intermediate product shown in Figure 7 is also a carrier 500 with an at least partially decoupled portion 510 to which the decorative surface layer 530 has already been attached. In this case, the carrier 500 has a hole 501, which is covered by a separate cover made of a more elastic material and is held in place by the decorative surface layer 530, forming the at least partially decoupled portion 510. It should be noted that the separate cover does not necessarily have to be made of a more elastic material, but can also be formed from a material with the same characteristics as the carrier, but with a groove similar to that shown in Fig. 6, which helps to create decoupling.

[0046] The Fig. 8a and Fig.8b shows carriers 600, 700 that can be produced using a 2K injection molding process. The carriers 600, 700 each have an at least partially decoupled section 610, 710 to which the respective decorative surface layer 630, 730 has already been attached. In the case of the carrier 600, the at least partially decoupled section 610 is created by a boundary layer 650 made of an elastic material, such as a soft elastomer. In the case of the carrier 700, the at least partially decoupled section 710 is formed by an elastic material, e.g., a soft elastomer.
