Description

[0001] The invention relates to a plug for a component, in particular of a vehicle, according to the preamble of patent claim 1. Furthermore, the invention relates to a holding arrangement of such a plug on a component.

[0002] A plug for closing an opening formed in a component is already known from the generic DE 10 2012 103 291 A1, DE 31 00 498 A1, and DE 20 2010 005 749 U1. These plugs each have a flange area with spring elements.

[0003] A plug for closing an opening formed in a component, in particular a vehicle, as well as a holding arrangement for such a plug on a component are also already known from DE 10 2009 032 243 A1. The plug is also referred to as a sealing plug or paint plug and has a base body made of a plastic, which is at least partially provided with an adhesive different from the plastic. In other words, the plastic and the adhesive are different materials. The plug further has a first wall formed by the base body, which can be at least partially inserted into the opening and which penetrates the opening, for example, when the plug is held on the component and closes the opening. In addition, the plug has a second wall formed by the base body for closing the opening.Furthermore, the plug has a first flange region that can be arranged on a first side of the opening and protrudes from the first wall. Furthermore, the plug has a second flange region that is opposite the first flange region and can be arranged on a second side of the opening opposite the first side and protrudes from the first wall.

[0004] Furthermore, WO 2004 / 085231 A1 discloses a plug for sealing holes in a vehicle body, comprising a central closure portion and an engagement portion arranged at the edge for receiving areas of the vehicle body. The closure portion and the engagement portion are formed from a plastic material. The plastic material of the engagement portion is softer than the plastic material of the closure portion. Finally, EP 1 375 308 A1 discloses a plug for sealing openings, in particular vehicle parts.

[0005] The object of the present invention is to further develop a plug and a holding arrangement of the type mentioned at the outset in such a way that the plug can be mounted particularly advantageously.

[0006] This object is achieved according to the invention by a plug having the features of patent claim 1 and by a holding arrangement having the features of patent claim 9. Advantageous further developments of the invention can be found in the remaining claims.

[0007] The plug mentioned above is characterized in that at least the first flange region has first spring elements of a first color formed by the base body, spaced apart from one another in the circumferential direction of the plug, and a sealing device of a second color different from the first color, formed by the adhesive, arranged in the circumferential direction of the plug between the respective first spring elements and surrounding respective free ends of the first spring elements. This means, for example, that at least one respective part of the sealing device and thus of the adhesive is arranged in pairs in the circumferential direction of the plug between each two of the first spring elements, so that at least one respective part of the sealing device and the adhesive is arranged between each two of the first spring elements directly following one another in the circumferential direction of the plug.Since the sealing device, and thus the respective part of the sealing device arranged between the respective first spring elements, has the second color and the respective first spring element has the first color different from the second color, and since the colors are visually perceptible to the human eye or to a person viewing the plug from the outside, the plug has a zebra-like external appearance, since, for example, the colors form respective, successive stripes. This external appearance of the plug allows the plug according to the invention to be particularly advantageously distinguished from other plugs, for example those designed as standard plugs and made of rubber, TPE (thermoplastic elastomer), or PVC (polyvinyl chloride), so that the probability of incorrect assembly can be easily kept particularly low.

[0008] The plug is mounted on the component during assembly, for example, and is inserted into the opening or at least partially pushed through the opening. This installation of the plug is performed manually, for example, by a person grasping the plug and inserting it into the opening. Due to the described external appearance of the plug, the person can easily distinguish the plug according to the invention from other, conventional plugs, thus preventing incorrect assembly.However, the external appearance is also advantageous, for example, in an automated assembly of the plug, since, for example, based on the external appearance, the plug according to the invention can be clearly detected and identified by an optical sensor, so that, for example, the plug according to the invention and not a different plug can then be assembled automatically, in particular by means of a robot.

[0009] The arrangement and design of the first spring elements and the sealing device also have a positive influence on the assembly itself, since, for example, the forces required to assemble the plug, which must be exerted on the plug, can be kept particularly low. This makes the plug particularly easy to install and thus time- and cost-effective. Furthermore, the fact that the sealing device surrounds the respective free ends of the first spring elements allows a particularly advantageous sealing function of the plug to be realized, so that the opening, designed, for example, as a through-opening, can be particularly well closed and sealed by means of the plug, designed, for example, as a lacquer plug.Thus, compared to conventional plugs, both a qualitative improvement in the sealing of the opening, for example, formed as a bore, and easier assembly can be achieved. Furthermore, the plug according to the invention can be manufactured particularly cost-effectively. Furthermore, compared to the use of conventional plugs, for example, a cost reduction can be achieved with regard to subsequent PVC application, since such subsequent PVC application for sealing can be avoided or kept to a minimum due to the advantageous sealing function of the plug according to the invention.

[0010] The respective first spring element or sealing device, for example, has the respective color on a respective, so-called visible side, which—as previously described—is visually perceptible to a person visually observing the plug from the outside, so that the person can visually perceive the respective color. This means that the respective visible side and thus the respective color are visually perceptible in the fully manufactured state of the plug and are not covered to such an extent that they can no longer be visually perceived.

[0011] The second flange region also has second spring elements formed by the base body, spaced apart from one another in the circumferential direction of the plug, and a second sealing device formed by the adhesive, arranged between the respective second spring elements in the circumferential direction of the plug and surrounding respective second free ends of the second spring elements. This allows for particularly simple assembly of the plug, while simultaneously providing an advantageous sealing function.

[0012] In order to be able to realize a particularly advantageous assembly and a particularly good sealing function of the plug, it is provided in a further embodiment of the invention that the first wall is provided on its outer side at least partially, in particular at least predominantly or completely, with the adhesive.

[0013] The adhesive can be activated, for example, by the application of heat, i.e., by warming or heating the adhesive. Such heating or heating of the adhesive occurs, for example, during a drying process in which at least one coating of the component, for example in the form of a lacquer layer, is dried, in particular by means of an oven. For this purpose, the coating is heated by means of the oven, which also heats the plug already held on the component and thus its adhesive. By activating the adhesive, the adhesive is cured, for example, and / or by activating the adhesive, it develops its adhesive effect, for example to bond the plug to the component.By bonding the plug to the component via the adhesive, a particularly advantageous sealing function can also be realized, since, for example, the adhesive is partially melted or partially melted during its activation or heating. In particular, as a result of its activation, the adhesive can, for example, conform or adhere particularly advantageously to the component, in particular to certain surface areas of the component, thereby creating a particularly advantageous, particularly cohesive, connection between the plug and the component, as well as a particularly advantageous sealing function.

[0014] A further advantageous embodiment of the invention provides that the respective spring element is completely surrounded by the adhesive in the circumferential direction of the respective spring element, except for a respective partial area via which the respective spring element is connected to the first wall. This allows for particularly simple and thus advantageous assembly, particularly compared to conventional plugs. The simpler assembly compared to conventional plugs is characterized in particular by lower insertion forces, so that the plug according to the invention can be installed particularly ergonomically, particularly manually. Furthermore, a particularly advantageous sealing function can be realized.The flange areas enable, for example, a sealing of the opening on both sides as well as a particularly advantageous tolerance compensation, in particular with regard to unevenness and / or diameter deviations of the opening, which is formed in the component, for example as a sheet metal or as a sheet metal component.

[0015] In a further embodiment of the invention, the adhesive is activatable from a temperature of 120 degrees Celsius. Upon activation, the adhesive reacts, for example, or chemical reactions are triggered within the adhesive, so that, for example, the adhesive develops its adhesive effect and / or cures during its activation. In other words, it is preferably provided that a chemical reaction of the adhesive occurs from as low as 120 degrees Celsius, or such a reaction of the adhesive occurs from as low as 120 degrees Celsius, so that a particularly advantageous seal can be achieved.

[0016] The plastic from which the base body is formed preferably has a higher hardness than the adhesive, so that the base body acts as a reinforcement for the plug and ensures sufficient rigidity against stone chips and / or other mechanical stresses on the plug. This allows the opening to be securely sealed even under high loads acting on the plug, such as those encountered during operation of the vehicle, which is particularly designed as a motor vehicle.

[0017] In a further embodiment of the invention, the first flange region has a larger outer circumference than the second flange region, thereby achieving a particularly advantageous seal for the opening. Furthermore, this allows the plug to be installed particularly easily, since, for example, only the second flange region, but not the larger first flange region, needs to be pushed through the opening to install the plug.

[0018] In a further advantageous embodiment of the invention, it is provided that the plug is produced by injection molding as a two-component component (2K component), which has the plastic as the first injection-molded component, in particular a plastic component, and the adhesive as the second injection-molded component, in particular a plastic component. The components are produced, for example, in the same mold of an injection molding tool by means of which a two-component injection molding process is carried out to produce the plug. In this case, the components are produced simultaneously, for example by injecting the components simultaneously into the mold. Furthermore, it is conceivable to first inject one of the components into the mold and, during this and / or after this, to inject the other component onto the one component.Thus, the adhesive, also known as glue, and the plastic forming the base body acting as a strength carrier are manufactured as a 2K component that adheres firmly to one another.

[0019] A further embodiment is characterized in that the second spring elements have the first color and the second sealing device has the second color, whereby the probability of incorrect assembly can be kept particularly low.

[0020] In order to be able to mount the plug particularly easily and at the same time to realize a particularly advantageous sealing function, a further embodiment of the invention provides that the second spring elements are arranged offset from the first spring elements in the circumferential direction of the plug.

[0021] In the holding arrangement according to the invention, the plug according to the invention is held on the component, wherein the plug is arranged, in particular at least partially, in the opening. The first wall penetrates the opening, wherein the first flange region is arranged on the first side and the second flange region is arranged on the second side opposite the first side. Advantages and advantageous embodiments of the plug according to the invention are to be regarded as advantages and advantageous embodiments of the holding arrangement according to the invention, and vice versa.

[0022] Details of the invention will become apparent from the description of the figures and the drawings. Herein: Fig. 1 a schematic and perspective top view of a plug according to the invention for closing an opening formed on the component; Fig. 2 a schematic sectional view of the plug along a Fig. 1 shown section line AA; and Fig. 3 a schematic sectional view of the plug along a Fig. 1 shown section line BB.

[0023] Fig. 1 shows a schematic and perspective top view of a plug, designated overall by 1, for closing an opening formed in a component. The component is, for example, a component of a vehicle, which is designed, for example, as a motor vehicle and in particular as a motor vehicle, such as a passenger car. The component is made, for example, of a metallic material and in particular as a sheet metal component. In particular, the component can be designed as a body component and thus be part of the body of the vehicle.

[0024] The opening is designed, for example, as a through-opening and is used, for example, as a drainage opening, in particular as a paint drainage opening. During vehicle manufacture, the component is at least partially provided with a coating, in particular with a paint coating, by applying the coating, in particular by spraying it, to the component in an initially liquid state, for example. It is also conceivable for the component to be provided with the coating by cathodic dip painting (CDP). In this case, the opening is used so that excess coating material can run off or drip off the component via the opening.

[0025] When the vehicle is fully manufactured, the opening opens into a cavity in the vehicle, for example. It is usually desirable to prevent dirt and moisture from penetrating the cavity through the opening during operation of the finished vehicle. The plug 1 is therefore used to close and seal the opening. When the vehicle is fully manufactured, the openings and thus the plug 1 can be arranged in an area of ​​the vehicle, in particular the body, which area is heavily exposed to dirt particles and / or moisture, for example while the vehicle is driving. It is desirable to be able to adequately seal the opening by means of the plug 1 despite such a high load acting on the plug 1.Such an area exposed to intensive water and dirt is typically located in the area of ​​the underbody of the vehicle body. Such an area and the plug 1 are typically constantly exposed to moisture and stone chips while the vehicle is in motion, whereby a secure sealing of the opening is desirable in order to ensure adequate overall vehicle quality.

[0026] How particularly good in conjunction with Fig. 2 and Fig. 3, the plug 1 has a base body 2 which is made of a plastic. As will be explained in more detail below, the base body 2 is at least partially, in particular at least predominantly, provided with an adhesive 3 that is different from the plastic. This means that the adhesive 3 and the plastic are different materials from one another, in particular different plastics from one another, wherein in particular the plastic or the base body 2 has a higher hardness than the adhesive 3. As a result, the base body 2 acts as a strength carrier of the plug 1, wherein by means of the strength carrier, sufficient rigidity and thus robustness against stone chips and / or other, in particular mechanical, loads acting on the plug can be realized.

[0027] The plug 1 has a wall 4 formed by the base body 2 and insertable into the opening, which, viewed in isolation, has the shape of an at least substantially round circular cylinder, for example, on both the outer and inner circumferences. Furthermore, the plug 1 has a second wall 5 formed by the base body 2 and thus integral with the wall 4, which wall 5 forms, for example, a base or a cover surface of the aforementioned straight circular cylinder. Thus, for example, the first wall 4 forms a shell, and the second wall 5 forms a cover or an end face of the aforementioned straight circular cylinder.

[0028] In Fig. 2 and Fig. 3 shows an axis 6, in particular a virtual or imaginary axis, which is, for example, a longitudinal axis, in particular the longitudinal central axis, of the right circular cylinder. For example, the wall 5 is arranged in a plane that runs at least substantially perpendicular to the longitudinal central axis, with the second wall 5 being used to at least partially, in particular to at least predominantly or completely, close the opening.

[0029] In this case, Fig. 2 Indentation areas B of the plug 1 can be seen. During assembly of the plug 1, the plug 1 is mounted on the component and held on the component by the plug 1 being inserted into the opening or at least partially through the opening. In particular, the first wall 4 is inserted into the opening in a plug-in direction coinciding with the longitudinal axis, so that the wall 4 penetrates the opening in a state in which the plug 1 is held on the component and inserted into the opening or arranged in the opening. In this case, at least a predominant portion of the opening is covered by the second wall 5 and thus closed. In particular, the entire opening is closed by means of the walls 4 and 5.With respect to the axis 6, the walls 4 and 5 are, for example, rotationally symmetrical, whereby, for example, the plug 1 is mirror-symmetrical with respect to a plane in which the axis 6 runs.

[0030] Out of Fig. 1 and Fig. 2 it can be seen that the plug 1 further comprises a first flange region 7 which can be arranged on a first side of the opening and protrudes from the first wall, which also protrudes from the second wall 5. In addition, the plug 1 comprises a second flange region 8 which is opposite the first flange region 7 and which can be arranged on a second side of the opening opposite the first side and protrudes from the first wall 4 and the second wall 5, which is particularly well-known from Fig. 2 and Fig. 3 can be seen. In the aforementioned state, in which the plug 1 is held on the component and arranged in the opening, the first flange region 7, the second wall 5 and optionally a first part of the wall 4 are arranged on the first side, while the second flange region 8 and at least a second part of the wall 4 are arranged on the second side.

[0031] In order to be able to realize a particularly advantageous and simple assembly of the plug 1, the first flange region 7 has first spring elements 9 formed by the base body 2 and spaced apart from one another in the circumferential direction 25 of the plug 1, having a first color, and a sealing device 11 formed by the adhesive 3, arranged in the circumferential direction 25 of the plug 1 at least between the respective first spring elements 9 and surrounding or enclosing respective free ends 10 of the respective spring elements 9, having a second color different from the first color. The first color is, for example, blue, and the second color is, for example, red. Fig. 1 shows that in the circumferential direction 25 of the plug 1, respective parts 12 of the sealing device 11 are arranged between each two spring elements 9 which are immediately adjacent to one another in the circumferential direction 25 of the plug 1, wherein the parts 12 are formed integrally with one another. Respective further parts 13 of the sealing device 11, which adjoin the parts 12 and are formed integrally with the parts 12, surround or enclose the respective free ends 10, so that, for example, the sealing device 11 forms a particularly well-defined Fig. 2 and arranged on the first side. In Fig. 1, the circumferential direction 25 of the plug 1 is illustrated by an arrow, wherein the circumferential direction 25 rotates around the axis 6.

[0032] The spring elements 9 form, for example, first stripes with the first color, with the parts 12, for example, forming second stripes of the second color. The stripes are arranged consecutively or alternately in the circumferential direction 25 of the plug 1, such that the plug 1 has an advantageous external appearance. As a result, the plug 1 can be particularly easily distinguished from conventional plugs, for example by a person installing the plug 1, so that the probability of incorrect assembly can be kept particularly low. This external appearance of the plug 1 offers advantageous visual differentiation from other, conventional plug variants, which are usually designed exclusively in black.

[0033] Out of Fig. 2 and Fig. 3 that the walls 4 and 5 form a hollow cross-section, in particular an open hollow cross-section 15, of the plug 1. The wall 4 is at least partially, in particular at least predominantly or completely, provided with the adhesive 3 on its outer side 16 facing away from the hollow cross-section 15 and facing the flange regions 7 and 8. As a result, the plug 1, in its previously mentioned state, is supported on the component via the adhesive 3 applied to the outer side 16, in particular on an edge region of the component that delimits the opening, completely circumferentially in the circumferential direction of the opening, whereby a particularly advantageous sealing of the opening can be achieved. Alternatively or additionally, the second wall 5 is at least partially, in particular at least predominantly or completely, provided with the adhesive 3 on its outer side 17 facing away from the hollow cross-section 15.

[0034] When fitting the plug 1, pressure forces are exerted on the pressing areas B, in particular by the person, in order to press or insert the plug 1 into the opening. By means of the described and particularly well-known Fig. The design and arrangement of the spring elements 9 and the sealing device 11, as can be seen in Figures 1 to 3, enables particularly simple and thus time- and cost-effective assembly of the plug 1, since the plug 1 can be mounted on the component with only low forces, in particular pressing forces. Furthermore, compared to conventional plugs, centering ribs for tolerance compensation can be omitted, since the plug 1 can compensate for tolerances particularly advantageously without the use of such centering ribs. The wall 5 is a central plug wall, which is arranged in the upper pressing areas B. This enables particularly simple assembly.

[0035] In the Fig. 3, the second flange region 8 also has second spring elements 18 ( Fig. 3) and one formed by the adhesive 3, arranged in the circumferential direction 25 of the plug 1 between the respective second spring elements 18 and respective second free ends 19 ( Fig. 3) the second spring elements 18 surrounding a second sealing device 20, so that in the second flange area 8 a second sealing lip 21 is also formed by the sealing device 20. The sealing lips 14 and 20 are formed to extend completely around the circumference 25 of the plug 1, so that the plug 1, in its aforementioned state, is particularly advantageously supported on the component via the sealing lips 14 and 21. This allows the opening to be sealed particularly well. Preferably, the second spring elements 18 have the first color and the second sealing device 20 has the second color. In other words, the spring elements 9 are enclosed by the adhesive 3, also referred to as glue, in order to obtain a uniform adhesive connection. The spring elements 18 functioning as lower springs are also enclosed by the adhesive 3 in order to obtain a uniform adhesive connection.

[0036] The base body 2 ensures, for example, sufficient dimensional stability of the plug 1, whereby, for example, the sealing lips 14 and 21 are held particularly well in support contact with the component. This allows the opening to be sealed particularly well. To achieve a particularly advantageous sealing function, it is provided, for example, that the second spring elements 18 are arranged offset from the first spring elements 9 in the circumferential direction 25 of the plug 1.

[0037] The respective sealing lip 14 or 21 also functions, for example, as a retaining lip, since the plug 1 is bonded or is bonded to the component via the adhesive 3, particularly in the area of ​​the respective sealing lip 14 or 21. Fig. 2 it is particularly clearly visible that the sealing device 20, in particular the sealing lip 21, forms an undercut and / or overpressure area with a particularly large adhesive surface 22, via which the plug 1 can be or will be adhesively bonded to the component. It is preferably provided that the adhesive 3 can be activated as of 120 degrees Celsius, so that, for example, an adhesive reaction begins as early as 120 degrees Celsius. The particularly large adhesive surface 22 enables the realization of secure adhesion to the component, which is designed, for example, as a body panel. Furthermore, tolerance compensation is thus possible, so that, for example, tolerance-related, different diameters of the openings can be compensated for.

[0038] The component is, for example, first provided with the coating while the plug 1 is not yet mounted on the component. If, for example, excess coating material has run off the component through the released opening and dripped off, the plug 1 is mounted on the component. The coating is then dried, for example, by heating the coating. In doing so, the coating and thus the component are heated together with the plug 1 and thus in a state in which the plug 1 is held on the component. As a result, the plug 1 and in particular the adhesive 3 are also heated, in particular by means of the aforementioned oven, wherein the adhesive 3 is heated, for example, to at least 120 degrees. As a result, the adhesive 3 is, for example, activated so that the adhesive 3 develops its adhesive function and / or is cured.As a result, the plug 1 is bonded to the component by means of the adhesive 3, particularly in the area of ​​the sealing lips 14 and 21, so that after the plug 1 has been bonded to the component, the plug 1 is held particularly firmly to the component.

[0039] To ensure particularly simple assembly and a particularly advantageous sealing function, the first flange region 7 has a larger outer circumference or outer diameter than the second flange region 8. Furthermore, to enable particularly cost-effective production of the plug 1, the plug 1 is manufactured by injection molding as a two-component component, comprising the plastic as the first injection-molded component and the adhesive 3 as the second injection-molded component. The plug 1 also offers the possibility of easily increasing the diameter of the lower sealing lip 21 via the geometry, particularly with regard to the thickness, length, and width of the hard spring elements 9 of the upper sealing lip 14.

[0040] In particular, the spring elements 9, which function as upper springs, serve to set a sufficient contact pressure so that the sealing lip 14 is pressed sufficiently strongly against the component. Furthermore, the upper springs (spring elements 9), for example, are used to expand the lower sealing lip 21. The spring elements 18, which function as lower springs, are used in particular to exert sufficient pressure on the adhesive 3 so that the adhesive 3, in particular the sealing lip 21, can be held particularly well in support of the component.

[0041] Overall, Fig.1 to 3 that the respective spring element 9 or 18 has a respective free end 10 or 19. This respective free end 10 or 19 is surrounded or enclosed by the adhesive 3, in particular with the formation of the respective sealing lip 14 or 21, in order to realize a uniform adhesive connection and sufficient sealing. In this case, the respective spring element 9 or 18 is completely surrounded by the adhesive 3 in the circumferential direction of the respective spring element 9 or 18, except for a respective partial region 23 or 24, via which the respective spring element 9 or 18 is connected to the wall 4 or held on the wall 4, in order to be able to realize a particularly advantageous sealing effect.
