Description

The present invention relates to a wind deflector for an openable roof of a vehicle and to a manufacturing method for producing such a wind deflector. In a further aspect, the invention relates to a sliding or rolling roof unit equipped with such a wind deflector.

STATE OF THE ART

Such wind deflectors are known from the prior art and serve to reduce noise at a roof opening of a vehicle. At provided for motor vehicles roof opening systems, such. As sunroofs and sliding-Aufstelldächern etc., usually Bügelwindabweiser for flow optimization and prevention of vibrations and resonances on a roof opening (overflowed cavity) are used. As a bow wind deflector, a wind deflector is considered, which is in the form of extending over an entire width of a roof opening of a roof opening system of a vehicle bracket, wherein two opposite longitudinal ends of the Bügelwindabweiser two pivot bearing sections are provided, each pivotally in two near the roof opening on a body the vehicle provided bearing mounts are to be mounted.

A wind deflector as described herein should in its basic function cause an airflow caused by the wind during driving with a vehicle over the roof opening or disturb the air flow in such a way that the best possible acoustics are achieved while avoiding oscillations and pitches in the vehicle.

In addition, induced bending vibrations as well as natural oscillations of the wind deflector triggers for further air and structural vibrations on the vehicle, resulting in noise, such. B. a roar (eg., A roof skin), can lead.

Such a wind deflector is already in the DE 10 2010 015 732 A1 described. Further wind deflectors for noise reduction at a roof opening of a vehicle are, for example, in DE 196 26 937 A1 . US 4,662,671 A and DE 196 43 234 C1 described.

In the DE 10 2005 063 099 A1 is a wind deflector disclosed in which the upper net strip in the longitudinal direction has a groove and is formed for example as aluminum or plastic profile. In the groove projections or depressions are at least partially formed. Thus, the net can be hooked or clamped in the groove by means of a connecting element.

The DE 10 2013 002 755 A1 discloses a wind deflector in which the upper and / or upper net strip are formed from a molded part as a fixing element, which is enclosed by a two-part shell. The casing consists of two injection molded components. The net is embedded between the injection molding components. This is implemented by a cohesive connection with the two injection molding components. The interface may have a projection or a recess for fixing the network.

The known wind deflectors have in common that they have an upper and lower net strip, which is attached to the front edge of the roof opening of the vehicle roof, in particular latched, clipped, screwed or otherwise secured. At the lower power strip is a wind net made of a textile, which is in particular permeable to air, for example, formed feinlöchrig plastic net connected. The wind net is stabilized in the open state by an upper net strip, which is pivotable relative to the lower net strip, and so spans the fabric when opening the roof and fixed. When closing the roof, the upper power strip pivots in the direction of the lower power strip and thus folds the wind net together in a rest position. In the open state, the upper net strip projects beyond the roof surface and may be shaped in the form of a closure lip, for example in the form of a microspoiler, which extends across the width of the roof opening. The upper power strip has a visible surface in the direction of travel, which determines the aesthetic overall impression of the vehicle when the roof hatch is open. The power strip has further visible surfaces, for example, the rear strip surface and in the direction of the vehicle interior facing surfaces and edges, which also determine the overall impression of the vehicle.

The known production methods for forming the upper net strip on the basis of a plastic injection-molded fasten the net in a first injection molding process by a so-called preform, ie with a plastic attachment structure, with the fixing, for example, a metal tube, in particular an aluminum tube, a plastic injection molding, a carbon profile, individual wires may be plastic, metal or a similar fixing element. For this purpose, recesses are provided in the aluminum tube, can penetrate through the plastic material to connect the network with the pipe by the viscous in the injection molding plastic. In a further injection molding process, the outer surface of the upper net strip is formed, wherein the pre-molded part Has spacing elements, in particular distance spins, to define a defined orientation of the semi-finished part in the injection mold for the finished part. The finished injection molding forms the visible edge of the upper power strip, which is obvious when the roof is open.

Due to this two-stage process of producing a preform in the interior of the net strip for attaching the network with the fixing and the Gesamtumspritzung the bar to form the strip surface, there is the problem that the mentioned spacer elements injection process to the surface of the visible edge rich. The visible edge thus has no homogeneous surface, since spacer elements of the pre-molded part are visible in the visible surface. In order to produce an eye-catching visible edge surface of the power strip, a further coating of the visible edge is necessary; alternatively, a manufacturing-related unsightly surface structuring remains due to outstanding spacer elements of the pre-molded part on visible surfaces of the wind deflector.

Based on the above-mentioned prior art, the object of the invention is to reduce the disadvantages of the known arrangements and methods. In particular, it is an object of the invention to provide a homogeneous and aesthetically sophisticated visible edge of the wind deflector.

The above-mentioned disadvantages are solved by an apparatus and a manufacturing method according to the independent claims. Advantageous developments of the invention are the subject of the dependent claims.

DISCLOSURE OF THE INVENTION

In a first aspect, a wind deflector for noise reduction at a roof opening of a vehicle, comprising a fan-foldable wind deflector textile net is proposed, wherein the textile net is bounded at its upper longitudinal edge by an upper net strip with a visible surface. The upper net strip has a fixing element, in particular a fixing tube, preferably an aluminum tube, which fixes and fixes the upper longitudinal edge of the net at least in sections with the upper strip. Such a rigid fixing element can, as it were, serve to stiffen the upper power strip, keep it dimensionally stable and reliably clamp the net even in extreme wind loads. The fixing element may nevertheless be an injection-molded plastic profile which merely fixes the net, the stiffening effect being provided by the plastic extrusion of the finished injection-molded part. For example, the fixing element may be one or more wires, in particular metal wires, or the fixing element may be formed as a carbon strip. Even injection-molded profile structures, in particular strip-like profile structures can be used as a fixing element.

It is proposed that a lower plastic half-shell molding attaches the net with the at least partially encapsulated in a first injection molding fixing by the first injection process, and thus establishes a connection between the network and fixing, wherein the visible surface of the upper net strip by one, in a second Injection molded upper half-shell molding is provided, and wherein a longitudinal cross-sectional area between the lower half-shell molding and upper half-shell molding of the upper net strip is formed. The visible surface mainly comprises the forward facing surface of the upper net strip in the vehicle direction, but also the rear-facing strip profile surface, as well as the upper end lip and downward in the direction of the vehicle interior facing areas that are visible to the vehicle occupants as well as passers-by with the roof open are.

Thus, a functional separation of the lower half-shell molding and the upper half-shell molding is achieved. The lower half-shell molding establishes the connection between the net and the fixing element, in particular metal or aluminum tube, and produces an outer surface of the lower region of the upper net strip. The upper half-shell spritzling serves the aesthetic decoration and defines a finishing lip with visible surface, which can be designed arbitrarily. This may be formed homogeneously, or may have a structuring or surface decorations, lettering or the like. The surface can be post-processed, for example, coated and obtained, for example, a metallic surface finish. Due to the surface homogeneity, thin surface layers can be applied, without any visible surface damage being visible.

The invention aims at a wind deflector for an openable vehicle roof. However, the inventive idea is not limited to this purpose and can for example be transferred to deployable network structures of solar or wind protection systems. Thus, deployable mesh or cloth solar panels or windscreen elements can be designed accordingly.

In an advantageous embodiment, the connection surface may be formed substantially in a longitudinal cross-sectional plane of the reinforcing element. Thus, the lower one embeds Halbschalenspritzling the fixing a, without the fixing is completely enclosed. Both half-shell elements each comprise subregions of the outer surface of the fixing element and are thereby reinforced. The fixing element may comprise recesses, for example bores, indentations or the like, so that plastic mass can pass through and form a positive connection.

In an advantageous embodiment of the lower half-shell molding a lower outer surface of the upper net strip and the upper half-shell molding an upper outer surface, in particular forms the visible surface of the upper net strip. The surface of the upper net strip is defined by the surface of both half-shell molded parts and can be designed individually, in particular homogeneously.

Basically, an actuator connection structure for connection to the opening mechanism of the openable roof is to be provided on the wind deflector, so that when opening the roof as it automatically ensures an extension of the wind deflector. Such Aktuatoranschlussstruktur may be formed on the lower half-shell molding in a first injection molding process, which makes the connection between the network and fixing in an advantageous embodiment, the upper half-shell molding actuator connection structures for fan-like opening and closing of the wind deflector comprise. The upper half-shell moldings, for example, terminal lugs, lever elements or the like form for connection with a Auffalt-lowering mechanism to open when opening the sunroof the wind deflector and fold when folding the wind deflector.

In an advantageous embodiment, the upper half-shell molding can form the visible surface as the leading edge surface of a form-elastic closing lip of the upper net strip. The final lip can be designed to be flexible in terms of shape, so that, on the one hand, there is a pleasant feel and a reduced risk of injury since the lip protrudes from the vehicle roof in its intended use. On the other hand, the final lip can be aerodynamically designed such that the wind resistance is reduced and wind noise is minimized.

In an advantageous embodiment, the lower half-shell molding of a mechanically dimensionally stable and resilient plastic and the upper half-shell molding of a form-elastic and soft plastic may be formed. In this further development, it is proposed that the lower half shell molding, which assumes a connecting and stabilizing function, mechanically stiffened and durable, and form the visible and protruding upper half-shell molding of a soft, haptic pleasant plastic. Thus, the different functions of both half-shell syringes can be accommodated by a suitable choice of material.

• – Einlegen des Netzes und eines Fixierelementes, insbesondere eines Fixierrohres in ein Spritzgusswerkzeug zur Ausbildung des unteren Halbschalenspritzlings;
• – Einspritzen eines Kunststoffs in einem ersten Spritzgussvorgang zur Ausbildung des unteren Halbschalenspritzlings, der das Netz und das Fixierelement verbindet;
• – Überführen des Vorspritzteils in eine zweite Spritzgussform zur Ausbildung des Fertigspritzlings, wobei der untere Halbschalenspritzling eine definierte Lagerung des Halbspritzlings in der zweiten Spritzgussform bereitstellt;
• – Einspritzen des oberen Halbschalenspritzlings in einem zweiten Spritzgussvorgang zur Fertigstellung des Fertigspritzlings und Ausbildung der Sichtfläche;

In a secondary aspect, the invention relates to a method for producing a wind deflector according to one of the preceding claims, comprising the steps:

• - Inserting the network and a fixing element, in particular a fixing tube in an injection mold for forming the lower half-shell molding;
• - Injecting a plastic in a first injection molding operation to form the lower half-shell molding, which connects the network and the fixing element;
• Transferring the preshaped part into a second injection mold to form the finished injection molding, wherein the lower half-shell injection molding provides a defined mounting of the half-injection mold in the second injection mold;
• - Injecting the upper half-shell molding in a second injection molding process for completing the Fertigspritzlings and forming the visible surface;

The manufacturing process is thus a two-stage process, wherein in the first stage, a semi-molded part is created by encapsulation of a lower half-shell around the fixing element and the network, which connects the network with the fixing element and provides a lower half shell of the power strip. The first half-shell defines in a second injection mold, the position of the pre-molded part and is sprayed in the second injection molding process with the upper half-shell, which forms the visible edge and the end lip of the upper edge of the network. The injection molding operations of both half-shells can be carried out effectively in succession in an injection molding machine in two part injection processes. Thus, the preform and the Fertigspritzling can be injected into immediately successive stations. Here, at the same time the lower net bar can be molded with. The preform does not need to be converted into another injection mold, but a part of the injection mold can be transferred with it remaining half-spatter in the station for the second injection molding process, wherein a Spritzgusshalbform to define the upper half-shell of the finished injection molding, which defines the visible surface and the end lip over slipped the lower part of the injection mold and the upper half-shell is sprayed onto the lower half-shell with fixing. Thus, the preshaped part can be converted into the second injection mold, wherein the preshaped in the lower injection half-shell of the first injection molding process can remain.

The connection between the first and second half-shell is usually formed by adhesion, i. a melting of the hot plastic masses during injection molding of the second, upper half-shell on the first, lower half-shell. It is also conceivable to provide connecting elements, for example metal or plastic hoops or projections on the partially encapsulated fixing means, or to provide in the pre-molded part, which are cast by the injection molding of the second half-shell, in order to increase the bonding strength between the upper and lower half-shells beyond the material bond to reach.

In an advantageous development of the manufacturing method, in the second injection mold at least one fixing element can be injection-molded onto the net, in particular TPE ribs, by opening a further cavity. The fixing fix in particular in the manufacturing process, the network with the top bar and can strengthen the mechanical stability of the network in the upper last region and thus provide in the folding and unfolding process for a defined network behavior.

In an advantageous development of the manufacturing process, in the first injection molding process for forming the lower half-shell molding, the fixing element can be partially encapsulated, in particular embedded up to a longitudinal cross-sectional area, so that the fixing element is completely encapsulated in the second injection molding process for forming the upper half-shell injection molding. Thus, the fixing is as it were enclosed by two half-shells, so that mechanical stresses can be derived symmetrically to the fixing, and arise both contact surfaces between the half-shell elements and between each half-shell element and the fixing.

In an advantageous development of the manufacturing method, the second injection molding process may include injection molding of actuator connection structures.

The Aktuatoranschlussstrukturen cause a leverage effect for folding and unfolding the wind deflector and can be connected to the opening mechanism of the sunroof. In order to provide a homogeneous appearance, it is advisable that the upper, visible half-shell injection molding also has the actuator connection structure, which has a mechanically relieving effect on the lower half-shell injection molding. The lower half shell fastens the net with fixing element and the upper half shell transmits the opening, closing and holding forces of the deployment mechanism to the wind deflector.

In an advantageous development of the manufacturing process, the first injection molding process can be carried out with a mechanically resistant and dimensionally stable plastic and the second injection molding process with a form-elastic and soft plastic. Hereby, as described above, the different functions of the two half shells are taken into account by different material properties.

In a further subsidiary aspect of the invention, a sliding or rolling roof unit for a vehicle is proposed, which comprises a wind deflector arranged on a front edge of the roof opening, which corresponds to an embodiment shown above. The sliding or rolling roof unit thereby enjoys the aforementioned advantages.

EMBODIMENTS OF THE INVENTION

In the figures, the same or similar components are numbered with the same reference numerals.

1 shows a perspective view of a partial section of a vehicle roof, a car 200 with a sunroof unit 202 that opens towards the rear of the vehicle. As a rule, such a sunroof 202 motor-driven. When opening the sliding roof 202 automatically becomes a wind deflector 10 extending along the leading edge of the vehicle 204 the roof opening unfolds, unfolds. The wind deflector 10 directs a wind flow over the roof opening, so that wind noise, in particular unpleasant wind resonance noises that occur at certain speeds, are suppressed. When closing the sliding roof 202 folds the deflector 10 , which includes a textile Windleitnetz, automatically in the leading edge 204 the roof opening, and remains visually unobtrusive. In the unfolded condition of the wind deflector 10 the upper net strip is a salient feature of the vehicle silhouette, with a high value on a visually flawless and freely configurable visible edge of the wind deflector especially for higher-priced vehicles 10 Value is placed.

In the 2 is a wind deflector 10 of the prior art. The wind deflector 10 includes a lower power bar 14 and an upper power bar 12 , The lower power bar 14 comprises a lower stiffening and fastening structure, in particular, a metal tube or the like may be enclosed in a plastic injection molded part for increasing stability. Basically, construction and manufacturing process of the lower, but not visible power strip 14 the construction and manufacturing process of the upper power strip 12 correspond. The lower power bar 14 has various stiffening and attachment structures 22 on, with which the bottom bar 14 fastened in a front edge of the sunroof, in particular in a sunroof frame, in particular snapped, clipped or screwed.

The lower power bar 14 is with a textile wind net 16 connected and spans this along the roof edge 204 on. A folding and folding takes place fan-like, wherein on curved flanks of the network stiffening ribs 24 for better lateral stability and defined folding movement of the network mounted on this, in particular can be sprayed. The stiffening ribs may be made of TPE, ie a thermoplastic polymer, in particular a rubber or rubber-like material and designed to be flexible.

The upper net bar 12 includes an inner fixation element 18 , in particular an aluminum tube or metal profile, in order to ensure a taut unfolding in the wind-exposed position and vibration of the wind deflector 10 to prevent. The power bar 12 will when opening the sunroof 202 issued over feathers and pulls the net 16 and tensions it against the wind. The upper net bar 12 has a visible surface 28 in the unfolded state protrudes above the roof surface and shapes the aesthetic shape of the vehicle silhouette. At the two bow-shaped curved longitudinal ends of the net bar 10 are actuator connection structures 26 for connection to a travel mechanism for folding and folding the wind deflector 10 , In particular iron or lever-like structures that interact functionally with the opening and closing mechanism of the sliding or folding roof. Due to manufacturing reasons, the visible surface 28 regularly arranged penetration points 40 a preform of the plastic injection part on which the net 16 with the internal fixing element 18 combines. These penetration points 40 form an unsightly surface of the visible surface 28 out, and are disturbing.

In the 3 to 6 is the perspective of the production of the wind deflector 10 illustrated in the prior art. This show the 5 and 6 enlarged partial representations of 3 respectively. 4 , The upper fixing element 18 the upper power bar 12 is with a preform 30 splashed over the net 16 with the fixing element designed as an aluminum tube 18 combines. Because the preform 30 only for connection of network 16 with fixing element 18 serves, he is in a subsequent injection of an in 4 Completely sprayed finished finished molding, which covers the outer surface of the power strip 12 provides. This is done in that in a first operation, the network 16 and the fixing element 18 placed in an injection mold and a plastic to form the pre-molded part 30 and the bottom power bar 14 is injected. In a second injection molding process, the pre-molded part 30 placed in a second injection mold and the envelope of the finished injection 36 the upper power bar 12 sprayed on, leaving a decorative surface of the visible surface 28 is created. In addition, by opening Another cavity, the stiffening ribs 24 For example, be sprayed as TPE ribs.

As in the 5 and 6 can be seen, comprises the pre-molded part 30 Definition of distance rings 32 as spacers, by several distance spins 34 per distance definition ring 32 are formed. These pins 34 define when inserting the preform in the second injection mold, the thickness of the outer wall of the Fertigspritzlings 36 , Naturally, the pins penetrate 34 the visible edge surface 28 at penetration points 40 , as in 4 , a partial section of the 6 represented. The penetration points 40 arise because material areas of the preform 30 to the outer surface of the Fertigspritzlings 36 rich, because in the second injection process, the entire outer surface of the upper power strip 12 is formed and spacers 38 of the preform 30 must be provided in the injection mold.

The trained as a tube fixing 18 will, as in 5 shown, with distance pins 34 to be sprayed over rings 32 are connected. The pins 34 hold the tube in the second pass 18 at a distance to the mold wall and prevent the pipe 18 from the top power bar 12 showing. The disadvantage of this is, as in 6 shown that the distance spins 34 outwards at penetration points 40 are visible, which is generally distracting. Furthermore, the pipe needs 18 usually be bored before the pins are sprayed on, which makes the manufacturing process more expensive.

The 7 shows in perspective an embodiment 100 a wind deflector according to the invention. This differs only slightly from a wind deflector at first glance 10 from the prior art, for example, in 2 is shown and has basically the same features. However, it becomes clear that due to the modified construction of the upper power strip 12 from two half-shells no penetration points 40 of spacers 38 in the visible area 28 are recognizable. In this way, a homogeneous surface can be achieved, further it is possible to manufacture the lower half shell of a hard, dimensionally stable and the upper half shell of a soft, rubbery plastic.

In the 8th and 9 are a lower half-shell shoot (preform) 102 and a Fertigspritzling with lower half shell 102 and upper half shell 104 an upper net bar 12 shown. In a first injection molding process, the lower half shell 102 as a preform to a fixing 18 , in this case molded aluminum tube, so that the net 16 attached to the aluminum tube, as shown in FIG 8th is shown. In this injection process are the network 16 and the fixing element 18 , In this case, an aluminum tube used in the injection mold and the plastic for the lower half-shell 102 and the bottom power bar 14 injected. Thus, the lower, in the installed position invisible lower power bar 14 be sprayed with in the first injection process. In the subsequent second injection process, in which, for example, above the lower half-shell injection cavity of the first injection process of the preform, an upper half-shell injection cavity can be applied within the same injection molding machine, the upper half-shell injection molding becomes 104 molded to the upper power strip 12 finish. As part of this operation, the rubber-like stiffening ribs 24 be injected to the network. Thus, the wind deflector 100 be sprayed on an invented injection molding machine in a combined, two-stage injection process. Such a special injection molding machine can be the top netlist 12 in a combined injection molding process, wherein the known from the prior art preform 30 to 3 not manually converted into another cavity and by means of distance definition rings 32 must be aligned. In the previous production of the pre-molded part 30 the first operation, a separate part, which stored temporarily and later with the Fertigspritzling 36 could be splashed. The geometry of the preform 30 made the conversion from a separate tool to a second tool absolutely necessary.

The preform 102 can be injected at a first station inside the injection molding machine in a preform cavity, after which further rotation of the injection mold, ie the cavity, in particular the cavity half shell and subsequent placement of a corresponding cavity half shell for the finished spray 104 the visible surfaces can be produced. In this case, a decorative visible surface can be formed. Simultaneously or subsequently, the stiffening ribs can be opened by opening a further cavity 24 be injection molded from TPE.

In the 10 and 11 are cross sections AA the 4 of the prior art or BB the 9 an embodiment of the invention shown. It is clear in 10 a spacer element 38 with penetration points 40a to 40d recognizable. The distance definition ring 32 penetrates with various distance spins 34 the visible surfaces of the Fertigspritzlings 36 at the penetration points 40 and forms unsightly surface structures. In contrast, shows 11 an upper net bar 12 an embodiment 100 invention, consisting of two half-shells 102 and 104 is composed, between which the fixing element 18 , in this case a pipe profile is included. The two half shells 102 . 104 are cohesively along a connection surface 106 connected, which is formed by melting the plastics. The plastic masses of the lower and upper half shell 102 . 104 can consist of the same or different plastics, which have different mechanical and haptic properties and can be colored individually.
