Description

Technical Field

[0001] This invention relates to an insulating element for insulating structural components in a motor vehicle. Furthermore, the invention relates to a system having a plurality of such insulating elements, and a method for mounting such insulating elements onto structural components. Background Technology

[0002] In many cases, components (such as the body and / or frame of vehicles, especially water, land, or air vehicles) have cavities to achieve lightweight construction. However, these cavities cause various problems. Depending on the type of cavity, it must be sealed to prevent the ingress of moisture and contaminants that can lead to corrosion of the component. It is also often desirable to significantly reinforce the cavity and therefore the component while maintaining a low weight. It is also often necessary to stabilize the cavity and therefore the component to reduce noise that would otherwise be transmitted along or through the cavity. Many of these cavities have irregular shapes or narrow dimensions, making them difficult to properly seal, reinforce, and dampen.

[0003] Therefore, baffles are used, especially in automobile manufacturing and aircraft and shipbuilding, to seal and / or acoustically isolate cavities, or reinforcers are used to strengthen cavities.

[0004] exist Figure 1 The diagram schematically illustrates the body of a car. The body 10 here has various structures with cavities, such as pillars 14 and beams or struts 12. These structural elements 12, 14 with cavities are typically sealed or reinforced with sealing and / or reinforcing elements 16.

[0005] The disadvantages of the sealing and / or reinforcing elements known to date are that they often cannot efficiently package such components. Furthermore, the transport of such components repeatedly leads to confusion and damage of individual parts. Summary of the Invention

[0006] Therefore, the object of the present invention is to provide an improved insulating element for insulating structural components in motor vehicles, which avoids the disadvantages of the prior art. This insulating element should, in particular, be able to be packaged and transported more economically.

[0007] This objective is achieved by an insulating element for insulating structural components in a motor vehicle, the insulating element comprising a carrier and an expandable material disposed on the carrier; wherein the insulating element has an upper side and a lower side, the upper and lower sides being oriented substantially in a plane of the cross section to be insulated in the service state, wherein the insulating element has at least three contact points on the upper side and on the lower side respectively, these contact points being designed such that, when multiple identical insulating elements are stacked, adjacent insulating elements are abutted vertically via these contact points and are thus arranged parallel to each other.

[0008] The primary advantage of this solution is that it provides a stackable insulating element. Therefore, these insulating elements can be stacked for packaging and transport. This results in transportation cost savings because the insulating elements can be packaged more space-efficiently, allowing more insulating elements to be transported within a given volume compared to conventional methods. Furthermore, this stacking of insulating elements makes it easier to identify confusion between different insulating elements. For example, if a first insulating element is packaged in a container with multiple second insulating elements, this immediately draws attention, as first insulating elements generally cannot be stacked with second insulating elements. This significantly reduces the likelihood of confusion.

[0009] The stackable insulating elements proposed herein also have the advantage of reducing the risk of damage to individual insulating elements through stacking arrangements for transport and storage. If individual insulating elements are transported loosely in a container as has been the case so far, this results in numerous contacts between the insulating elements, sometimes leading to damage. However, transporting insulating elements in a stacked manner significantly reduces the number of mechanical contacts between them. Furthermore, the insulating elements can be configured such that the contact portions are designed to be robust or resistant to damage, and / or that vulnerable portions of the insulating element are located in protected positions, such as those covered by adjacent insulating elements in the stack.

[0010] Furthermore, the stackable insulating elements presented herein have the advantage of facilitating the automated installation of insulating elements onto structural components in motor vehicles. Thus, for example, an entire stack of such insulating elements can be loaded into a robot, which then removes the individual insulating elements from the stack and installs them accordingly onto the structural components. Such automated installation of insulating elements is much more difficult when they are loosely arranged in a container.

[0011] The term "insulating element" in this invention includes elements used for isolating and / or sealing and / or enclosing and / or reinforcing and / or insulating structural elements. These different characteristics of such insulating elements may appear individually or in combination.

[0012] In this invention, the terms "upper side" and "lower side" respectively refer to the two main surfaces or the two largest sides of the insulating element. Since the insulating element is designed to enclose the cross-section in a structural element, this means that the upper and lower sides are substantially located in the plane of the cross-section to be insulated in the application. Here, the upper or lower side can also have a stepped feature; that is, the upper or lower side is not necessarily designed to be completely flat.

[0013] In relation to the arrangement of insulating elements in a stack of multiple identical insulating elements, the term "parallel" in this invention means that the same faces and / or edges of the same insulating elements are arranged substantially parallel to each other.

[0014] In one exemplary embodiment, the insulating element has exactly three contact points on its upper side and on its lower side, which are positioned vertically when adjacent insulating elements are stacked.

[0015] In one alternative development, the insulating element has exactly four or at least four such contact points on the upper and lower sides.

[0016] In another alternative embodiment, the insulating element has exactly five or at least five such contact points on the upper side and the lower side.

[0017] In one exemplary embodiment, at least one contact point on the upper side and a corresponding contact point on the lower side are configured such that adjacent insulating elements are prevented from moving horizontally when stacked in the vertical direction.

[0018] In one exemplary development, at least one contact point on the upper side and a corresponding contact point on the lower side are configured such that a mechanical stop is formed between the respective contact points during stacking.

[0019] In one exemplary embodiment, a contact point on the upper side is designed as a first coupling element, and a corresponding contact point on the lower side is designed as a second coupling element, wherein the first and second coupling elements are interlocked when stacked, thereby forming a temporary fixation of adjacent insulating elements.

[0020] In one exemplary embodiment, at least one contact point is located in a region of a fixed element.

[0021] In this invention, "the area of ​​the fixing element" refers to the fixing element itself, the base of the fixing element, and the expandable material on the base of the fixing element, which is used to seal the opening in the structural element into which the fixing element is inserted.

[0022] In one exemplary embodiment, the fixing element is designed as a clip.

[0023] In one exemplary embodiment, the height of the fixing element along the stacking direction is less than 8 mm, preferably less than 7 mm, and particularly preferably less than 6 mm.

[0024] In one exemplary embodiment, the height along the stacking direction of the base of the fixing element includes both the base of the fixing element and the expandable material on the base of the fixing element, which is used to seal the opening in the structural element into which the fixing element is inserted, and the height is at most 130%, at most 120%, or at most 110% of the height of the fixing element along the stacking direction.

[0025] This relatively tall design has advantages: it allows for more space-efficient packaging of insulating components.

[0026] In one exemplary embodiment, at least one contact point is designed as a spacer element, wherein the spacer element is used to support and / or position the insulating element on the structural element when the insulating element is used in the structural element.

[0027] In one exemplary development, the spacer elements are configured to be stackable, wherein two spacer elements stacked together have a total height along the stacking direction that is at most 170%, 160%, 150%, 140%, or 130% of the height of a single spacer element.

[0028] In one exemplary embodiment, the carrier steps form an angle of at least 35°, at least 40°, at least 45°, at least 50°, or at least 55° relative to the stacking direction.

[0029] The advantage of this stepped configuration is that insulating elements with flatter steps can be stacked better than those with steeper steps. In cases with steeper steps, there is a particular problem that adjacent insulating elements cannot be vertically aligned without horizontal offset.

[0030] In one exemplary embodiment, at least one contact point is designed as a support element that protrudes from the overall surface of the upper or lower side of the insulating element along the stacking direction.

[0031] In one exemplary embodiment, all or individual contact points are formed by a carrier.

[0032] In an alternative implementation, all or individual contact points are made of an expandable material.

[0033] In another embodiment, at least one contact point is formed by a carrier, and at least one contact point is formed by an expandable material.

[0034] Since carriers can typically be manufactured with smaller tolerances than expandable materials, it is advantageous to form contact points through carriers whenever possible.

[0035] In one exemplary embodiment, the insulating element has at least one safety element designed such that, in the case of stacked insulating elements, one insulating element is prevented from moving laterally in the stacking direction and / or from rotating about the stacking direction by the safety element of the adjacent insulating element.

[0036] In one exemplary embodiment, the safety element is designed such that, in the case of stacked insulating elements, the safety elements of two adjacent insulating elements overlap along the stacking direction.

[0037] In one exemplary development, the fuse elements overlap by at least 3 mm, at least 5 mm, or at least 7 mm along the stacking direction.

[0038] In one exemplary embodiment, the safety element has at least one guide surface designed such that, during stacking, the guide surface guides an insulating element to be stacked, thereby substantially overlapping the newly stacked insulating element on the insulating element along the stacking direction.

[0039] In one exemplary embodiment, at least one spacer element is configured as a safety element.

[0040] In one exemplary development, the spacer element is configured to be substantially Y-shaped. For example, the faces of the extension arms of the Y-shaped spacer element can be configured as guide surfaces.

[0041] In one alternative development, the spacer element is essentially U-shaped or V-shaped. Here, the faces of the extension arms of the U-shaped or V-shaped spacer element can also be configured as guide surfaces.

[0042] In one exemplary embodiment, at least one step is configured as a safety element.

[0043] In one exemplary embodiment, at least one region of the fixing element is configured as a safety element.

[0044] In one exemplary development, a base of the fixing element is configured as a safety element. Here, this base can be designed, for example, to be substantially U-shaped. Furthermore, the faces of the extension arms of the U-shaped base of the fixing element can also be configured as guide surfaces.

[0045] In one exemplary implementation, all or individual fuse elements are constructed via a carrier.

[0046] In an alternative implementation, all or individual safety elements are made of an expandable material.

[0047] In another embodiment, at least one safety element is constituted by a carrier, and at least one safety element is constituted by an expandable material.

[0048] Since carriers can typically be manufactured with smaller tolerances than expandable materials, it is advantageous to construct safety elements using carriers whenever possible.

[0049] In principle, any material suitable for foaming can also be used as an expandable material. This material may or may not have reinforcing properties. Typically, expandable materials expand due to heat, humidity, or electromagnetic radiation.

[0050] Such expandable materials typically include chemical or physical blowing agents. Chemical blowing agents are organic or inorganic compounds that decompose under the influence of temperature, humidity, or electromagnetic radiation, with at least one decomposition product being a gas. Physical blowing agents, for example, are compounds that become gaseous aggregates when the temperature rises. Thus, both chemical and physical blowing agents can create foam structures within polymers.

[0051] The preferred expandable material is thermally foamed, using a chemical blowing agent. Suitable chemical blowing agents include, for example, azodicarbonamide, sulfonyl hydrazine, bicarbonate, or carbonate. Suitable blowing agents are also available, for example, from AkzoNobel (Netherlands) under the trade name... Or from Chemitura, a US company, under the brand name Commercial purchase.

[0052] The heat required for foaming can be introduced by an external or internal heat source, such as an exothermic chemical reaction. Foamable materials are preferably foamable at temperatures ≤250°C, especially 100°C to 250°C, preferably 120°C to 240°C, and most preferably 130°C to 230°C.

[0053] Suitable expandable materials are, for example, single-component epoxy resin systems that do not flow at room temperature, particularly those with increased impact toughness and containing thixotropic agents such as vaporized silica or nanoclay. Such epoxy resin systems, for example, contain 20 to 50 wt% liquid epoxy resin, 0 to 30 wt% solid epoxy resin, 5 to 30 wt% toughening modifier, 1 to 5 wt% physical or chemical foaming agent, 10 to 40 wt% filler, 1 to 10 wt% thixotropic agent, and 2 to 10 wt% heat-activated curing agent. Suitable toughening modifiers are reactive liquid rubbers based on nitrile rubber or polyether polyurethane derivatives, core-shell polymers, and similar systems known to those skilled in the art.

[0054] Equally suitable expandable materials are one-component polyurethane compositions containing a foaming agent, which are composed of a crystalline polyester containing OH groups, a polyol, preferably a polyether polyol, and a polyisocyanate with end-capped isocyanate groups. The melting point of the crystalline polyester should be ≥50°C. The isocyanate groups of the polyisocyanate can be end-capped, for example, with nucleophiles such as caprolactam, phenol, or benzoxone. Furthermore, end-capped polyisocyanates, such as those used in powder coating technology and commercially available from Degussa GmbH in Germany under the trade names Vestagon BF 1350 and BF 1540, are also suitable. So-called encapsulated or surface-deactivated polyisocyanates, known to those skilled in the art and described, for example, in EP 0 204 970, are also used as isocyanates.

[0055] In addition, two-component epoxy / polyurethane compositions containing a foaming agent, such as those described in WO 2005 / 080524 A1, are also suitable as expandable materials.

[0056] In addition, ethylene vinyl acetate mixtures containing foaming agents are also suitable as expandable materials.

[0057] Similarly suitable expandable materials, such as those marketed under the trade name, are also suitable. 240. 250 or 255 is sold by Sika, Inc. of the United States and described in US 5,266,133 and US 5,373,027. This expandable material is particularly preferred for the present invention.

[0058] Preferred expandable materials with reinforcing properties, such as those from Sika Corporation of the United States under the trade name... The material sold under 941. This material is described in US 6,387,470.

[0059] In one exemplary embodiment, the expandable material has an expansion rate of 800% to 5000%, preferably 1000% to 4000%, and particularly preferably 1500% to 3000%. The advantage of an expandable material with such an expansion rate is that it allows for reliable sealing or insulation of structural elements from liquids and sound.

[0060] In one exemplary embodiment, the expandable material is configured as a temperature-inducing material.

[0061] This has the following advantages: a furnace can be used to bake the impregnation liquid, causing the expandable material to expand and thereby insulate the cavity. Therefore, no additional working steps are required.

[0062] The carrier can be made of any material. Preferred materials are plastics, especially polyurethane, polyamide, polyester, and polyolefin; preferably high-temperature resistant polymers such as polyphenylene ether, polysulfone, or polyethersulfone, which are also foamed; metals, especially aluminum and steel; or grown organic materials, especially wood or other (pressed) fibrous materials or glassy or ceramic materials; especially such foamed materials; or any combination of these materials. Polyamides, especially polyamide 6, polyamide 6,6, polyamide 11, polyamide 12, or mixtures thereof, are particularly preferred.

[0063] Furthermore, the carrier can be solid, hollow, foamed, or have a mesh-like structure. The surface of the carrier can typically be smooth, rough, or structured.

[0064] In the case of an insulating element where the expandable material is located on a carrier, the manufacturing process differs depending on whether the carrier is made of a material that can be injection molded. If so, a two-component injection molding method is typically used. First, the first component, in this case, the carrier, is injected. After the first component has cured, the cavity in the mold is enlarged or adjusted, or the die-cast part is placed in a new mold, and then the second component, in this case, the expandable material, is injected onto the first component using a second injection unit.

[0065] If the carrier is made of a material that cannot be produced by injection molding, such as metal, the carrier is placed in a suitable mold and the expandable material is injected onto the carrier. Alternatively, the expandable material can be fixed to the carrier using special fixing devices or methods.

[0066] In addition, the carrier can also be manufactured by other methods, such as extrusion.

[0067] The insulating element has a stacking height that corresponds to the additional height of a stack with the insulating element along the stacking direction, which is increased when another insulating element is stacked on top of the stack.

[0068] In one exemplary embodiment, the stacking height of the insulating elements is at most 80% of the total height of a single insulating element along the stacking direction, preferably at most 70%, preferably at most 60%, preferably at most 50%, preferably at most 40%, and preferably at most 30%.

[0069] This has the following advantages: it allows for more space-efficient placement of insulating elements within a single stack. Furthermore, the increased stability of the entire stack is achieved through stronger vertical nesting of adjacent insulating elements within the stack.

[0070] Furthermore, the objective stated at the beginning is achieved through a system with multiple such insulating elements, which are stacked one on top of the other.

[0071] In one exemplary embodiment, the system includes at least 10, or at least 15, or at least 20, or at least 25, or at least 30 stacked insulating elements.

[0072] In another exemplary embodiment, the system includes up to 150, or up to 120, or up to 100, or up to 80, or up to 60 stacked insulating elements.

[0073] In one exemplary embodiment, the insulating element at the bottom of the stack rests flat on a base element.

[0074] Setting up such a base element has advantages: it allows stacks of insulating elements to be placed on a single surface. Furthermore, such a base element can be used in automated process flows.

[0075] In one exemplary embodiment, an additional insulating element increases the stack by a maximum of 20 mm, particularly preferably a maximum of 18 mm, particularly preferably a maximum of 16 mm, particularly preferably a maximum of 14 mm, particularly preferably a maximum of 12 mm, and particularly preferably a maximum of 10 mm.

[0076] Stacking insulating elements tightly has the advantage of allowing for more efficient packaging of the insulating elements.

[0077] In one exemplary embodiment, the stacking height of a single insulating element is at most 80% of the total height of the single insulating element along the stacking direction, preferably at most 70%, preferably at most 60%, preferably at most 50%, preferably at most 40%, and preferably at most 30%.

[0078] Stacking insulating elements tightly also has the advantage of allowing for more efficient packaging of the insulating elements.

[0079] Furthermore, the objective stated at the beginning is also achieved by a method for mounting insulating elements onto structural elements in a motor vehicle, the method comprising the steps of: providing a system as described above, having stacked insulating elements; loading the system into an application robot; removing a single insulating element from the system; transferring the single insulating element via a robotic arm; and mounting the insulating element onto a structural element of the motor vehicle.

[0080] In one exemplary implementation, multiple systems are simultaneously mounted on the application robot.

[0081] In one exemplary implementation, a single insulating element is removed by a robotic arm. Attached Figure Description

[0087] exist Figure 2a The diagram first shows a single insulating element 16. This insulating element 16 has a carrier 11 and an expandable material 13 disposed on this carrier 11. The insulating element 16 is designed to be substantially flat so as to effectively insulate the cross-section of a structural element in use. However, the insulating element 16 is not designed to be completely flat, but has several different ridges and stepped steps, particularly a steep step 5.

[0088] The insulating element 16 here has an upper side 17 and a lower side 18. In addition, in this embodiment, the insulating element 16 has two fixing elements 3 respectively designed as clips, and two spacer elements 4 respectively positioned on different sides.

[0089] In addition, the insulating element 16 has a support element 6, which in this embodiment is disposed on the upper side 17 of the insulating element 16.

[0090] In this embodiment, the insulating element 16 has three contact points disposed on the upper side 17 and three corresponding mating contact points disposed on the lower side 18. Here, two contact points are disposed in the region of the fixing element 3, and the other contact point is designed as a support element 6 or a support point on the lower side 18 of the insulating element 16.

[0091] exist Figure 2b In the middle, a structure with multiple Figure 2a The system 1 shown is an insulating element 16. The insulating elements 16 are stacked along the stacking direction 19. Here, the stacked insulating elements 16 are arranged parallel to each other and overlap each other at the contact points on their upper and lower sides, respectively.

[0092] exist Figure 2c The image shows a stack or system 1 with stacked insulating elements 16, wherein in this embodiment the insulating element 16 at the bottom of the stack is fixed to a base element 2.

[0093] exist Figure 3 The diagram schematically illustrates an exemplary mechanical stop 7 between two adjacent insulating elements. Here, a first coupling element 8 of the lower insulating element is embedded in a second coupling element 9 of the upper insulating element. In this way, stacked insulating elements can be secured, for example, to prevent horizontal movement and also partially to prevent movement in other directions.

[0094] exist Figure 4 The diagram illustrates another exemplary system 1 with stacked insulating elements 16. As can be seen in this diagram, each additional insulating element 16 increases the stack height by a stack height 15 of the insulating element 16.

[0095] exist Figure 5 The image shows a partial view of two stacked exemplary insulating elements. In this embodiment, a region of the fixing element 3 (i.e., the expandable material 13 disposed around the base of the fixing element 3) constitutes a contact point. The upper and lower fixing elements 3 do not contact each other here. Furthermore, this partial view shows two spacer elements 4 for each insulating element 16. The spacer elements 4 are designed as safety elements in this embodiment, preventing lateral movement of the insulating elements in the stacking direction and rotation of the insulating elements about the stacking direction. The spacer elements 4 have a generally Y-shaped form, with the extension arms forming guide surfaces as positioning aids during stacking. Additionally, the spacer elements 4 of adjacent insulating elements overlap along the stacking direction.

[0096] Finally, Figure 6A portion of an exemplary insulating element 16 is shown. Here, in particular, a region of the fixing element 3 can be seen. This region of the fixing element 3 includes both the fixing element 3 itself, designed as a clip, and the base of the fixing element 3 and an expandable material 13 disposed on the base of the fixing element 3 and used to seal an opening in the structural element into which the fixing element 3 can be inserted.

[0097] In this embodiment, the height 21 on the base of the fixing element 3 is indicated. This height 21 on the base includes both the base of the fixing element and the expandable material on the base of the fixing element, which is used to seal the opening in the structural element into which the fixing element can be inserted.

[0098] In addition, the height 20 of the fixing element 3 itself is also marked.
