Description

DOOR MODULE SUPPORT WITH A BASE BODY, METALLIC, FOR THE CLOSURE OF AN OPENING IN A DOOR OF AN ENGINE VEHICLE DESCRIPTION The invention relates to a door module support with a metallic base body for closing an opening in a door of a vehicle according to the preamble of claim 1. A door module support is a part component that is usually made of a virgin metallic piece, laminated in which the function elements of the vehicle door are fixed, such as the motor of the window lift and the rails, guiding elements or loudspeakers Door fitted in this way is assembled as a complete structural unit on the inner panel of the door, where it then closes an opening that has been worked into the inner door panel. In this way, the function elements are easily mounted on the door module support and the opening that has been worked on the inner door panel can be closed, sealing against moisture.

In order to produce this opening, generally during the processing of the inner door panel, a metal, laminated, large surface part is cut or perforated from a virgin, metal, laminated, closed part. Usually, the material that has been cut is collected and passed to a separate manufacturing process, or recycled. In DE 41 37 481 C2 a method is described for recovering the cut sections that have accumulated during the processing of the interior door panels so that during the formation of the interior door panel a so-called secondary part is formed when cutting or perforating several small areas of the inner door panel, whereby the secondary part at the beginning remains connected to the inner door panel through the connecting frames. After the additional processing steps, the secondary door is separated from the inner door panel and reused according to its configuration in an area of use outside the vehicle door. The object of the present invention is to improve the processing of a door module support with respect to the amount of material used and manufacturing costs. According to the invention, this is achieved through a door module support with a metallic base body having the features of claim 1. Through the design of the support of the door module according to the invention with a body metallic base, it is also possible to use laminated metal parts to make the door module supports whose external control does not completely cover the edge of the opening. By edge of the opening is meant an area of the inner door panel which is directly connected to the opening and which forms a contact location surface for the metallic base body, which runs in this manner substantially parallel to the extension of the surface flat of the base body. In a further advantageous development of the invention, the outline of the metallic base body substantially corresponds to the contour of the opening, so that sections of the cut material that arise when the opening is made in a door of a vehicle, can be additionally used. to manufacture a door module support.

Additionally, the support covers, the sealing elements or the fastening parts can also be integrated into the base body in a simple manner, whereby manufacturing costs are reduced. The weight of the complete support of the door module is also reduced. Advantageously, the formed plastic sections are formed with an enlarging contour so that the section of cut material that was cut or punched from the inner door panel to produce the opening can be mounted to the inner door panel after the union of the plastic sections. The outer contour of the complete door module support, in this way the metallic base body with the molded plastic sections projects in this way over the contour of the opening. As an alternative, the plastic section is arranged circumferentially so that the connection between the door module support and the inner door panel is completely produced through the overlapping plastics. This occurs preferentially when injecting or molding the plastic in the metallic base body, more particularly using Outsert technology. In order to ensure a uniform fixing of the door module support on an inner door panel, one or more fixing points are provided on the molded plastic sections. These fastening points can be formed as either positive or force fastening connecting points, such as for example molded staples or press fittings, or as through guides for fastening means such as screws, rivets or other retention bolts. You can mark threads or reinforcements in the guides. In order to ensure separation between the wet and dry cell and to increase the degree of integration in a further embodiment of the invention, at least one area of the plastic sections is formed as a separate seal or seal is mounted in the plastic. In this way, it is possible that the part of the metallic base body which is not provided with a molded plastic section, protrudes over the contour of the cut-out door section so that the base, metallic body overlaps directly with the inner panel of door.

In order to obtain the highest possible proportion of direct connections between the door module plate and the inner door panel, in order to thereby achieve a greater overlap between the metallic base body and the inner door panel, the contour of the opening and the contour of the metal base body are formed in a labyrinth shape or a regular wave pattern so that by compensation of the metallic base body by the dimension of a labyrinth or wave curve, each of the two areas Laminated metal sheets can overlap each other. Preferably, the contours in the form of a labyrinth are located on opposite lateral surfaces, while the lateral surfaces crossing the proposed direction of travel do not need to have this contour. Tabs may be provided on the outer contour of the metallic base body, for example by reinforcement. The tabs are preferably arranged uniformly and integrally mounted on the door module plate. The formation of the tongues is preferably carried out when the base, metallic body is cut. If depressions are provided in the inner door panel then it is advantageous to form the tabs of the metal base body corresponding to these depressions so that the depressions are covered by the tabs. If the plate of the door module has not been made of rolled metal from the opening to be closed, then the tabs can also be added later, for example by welding or in a common process of reforming the module plate of door. In order to ensure separation between the wet cell and the dry cell, the areas between the tabs are filled with a sealant wherein the sealant consists of for example plastic or other sealing material. In order to mold the plastic sections on the outer contour of the metallic base body, expression points are provided on the tabs of the metal base body, arranged in a corresponding manner to the fixing points on the inner door panel. These fixing points can be formed as through marked guides or reinforcements or threads or as fixing bolts, threaded rods, plastic, molded as well as staples or snap fittings.

In a further advantageous development of the invention, it is proposed that the function elements be arranged or molded in the door module support, where it is appropriate to form them from plastic for reasons of economic production. The function elements can be formed as connection joints for a door latch, such as fastening bolts or as fastening clips, mounting elements for cable shafts, bearings or gear parts, hollow bodies, for example for holding loudspeakers and other insertion parts, as well as guide elements for cable window elevators. In order to reduce the weight of the door module support, the areas of the metal base body can be cut and closed by means of a plastic, metal or foam insert. In this way, light weight materials can be easily used, particularly in those places where it is subjected to less mechanical stress. Now the idea on which the invention is based will be explained, in further detail with reference to the modalities illustrated in the drawings, in which: Figures 1 and 2 show side views of a vehicle door with a section cut from the inner door panel and closed by a door module holder; Figure 3 shows a detailed view of a section cut from the door and a base body, metal; Figure 4 shows a metal base body with molded function elements and plastic sections, and Figures 5 and 6 show complete views of the door module supports.

Figure 1 shows a vehicle door 10 having an opening 11 partially closed by a metal base body 1. The metallic base body 1 corresponds in its external contour to the contour of the opening 11 and is formed in the illustrated embodiment as being predominantly rectangular. On a long side and on a narrow side, plastic sections 2 are molded into the base metal body 1 and the outer contour of the metal base body 1 is enlarged so that the edge 12 of the opening 11 is completely covered. From the combination of the metal base body 1 and the molded plastic section 2, a door module support 100 is formed which completely closes the opening 11 in the interior door panel 5. When fixed to the support 100 of the door module in the interior door panel 5, the metal base body 1 is set compensated to join the interior door panel 5, as indicated by the arrow A. The area of the opening 11 which not covered by the body 1 metal base is thus closed by the plastic section 2, molded so that a flat surface contact support is produced by the metal base body 1 and the plastic section 2 against the panel 5 door interior. The edge 12 is thus completely covered parallel to the flat surface extension of the metal base body 1 and the inner door panel 5 so that a separation occurs between the wet and dry cells, thus a moisture tight seal. of the opening 11. Figure 2 shows a vehicle door 10 which is similar in construction to that of Figure 1, but the opening 11 is larger on all sides than the metal base body 1, and for fixing the support 100 of the door module in the interior door panel 5, a section 2 of plastic, circumferential in the metallic base body 1, is injected. The fixing of the support 100 of the door module on the inner door panel 5 is only through the plastic section 2 and a direct covering on the edge 12 of the opening 11 is not provided by the metal base body 1. In this embodiment, the edge 12 of the opening 11 is covered by the plastic section 2. A direct super imposition of the metallic base body 1 on the inner door panel is not provided. Figure 5 shows a detailed view of the edge area of the metallic base body 1 and the inner door panel 5. The external contour of the metallic base body 1 is thus formed of a regular labyrinth shape and has tabs 6 on which the fixing points 3 are mounted. Between the tabs 6 are seals 20 each consisting of plastic or other sealing material and injected or molded into the metallic base body 1. The outline of the inner door panel 5 is also of a mandrel shape and corresponds to its dimensions to the contour of the metallic base body 1. If the metallic base body 1 has been made from the inner door panel 5 by means of a separation process, the outline of the metallic base body 1 and the contour of the inner door panel 5 form a shape positive and negative one with respect to the other. In the inner door panel 5, fixing points 13 are also arranged which are at the same intervals as the fixing points 3 of the metal base body 1. By sliding the metal base body 1 in the vertical and horizontal directions, as is indicated by the arrow A; the fixing points 3 and the fixing points 13 are aligned with each other so that a direct connection between the metallic base body 1 and the inner door panel 5 can be produced by means of these fixing points 3, 13. openings that arise when the fixing points 3, 13 overlap each other are closed by the seals 20 that are arranged between the tongue 6. The seals 20 can be connected together through a circumferential seal, for example, through a sealing cap joining the tabs 6 so that a continuous seal is formed. Depending on the type of mounting proposed, the fixing points 3, 13 consist of depressions, such as holes or perforations, or of threads. After the fixing points 3, 13 have been aligned with each other, the metallic base body 1 and the inner door panel 5 can be connected together by means of screws, rivets or other means of f igating. A further possibility for designing the fixing points 3, 13 consists of molding clamps or press fit elements in the metallic base body 1 and in the formation of depressions in the inner door panel 5 so that the fixing points 3 of the metallic base body 1 after alignment with the fixing points 13 of the inner panel 5 of the door have only to be pressed in or on each one. Obviously, the depressions and staples or press fit elements can also be arranged in reverse or in plastic sections 2. Figure 4 shows a complete support 100 of the door module consisting of a metallic base body 1, as well as a plastic section 2, circumferentially joined. Different function elements are formed in the support 100 of the door module, for example, guide elements 33 for a cable window elevator, staple elements 34 for stopping component parts such as electronic control products or interior trim as well as a fixing bolt 36 on which the components can also be arranged or mounted inside the vehicle door. The cutting sections from the metallic base body 1 are likewise filled with inserts 32 in order to achieve a reduction in weight. These insert pieces 32 may consist of plastic or metal foam. These cut sections are preferably provided in other places that are subjected to less mechanical stress. Additionally, a hollow plastic body 31 is molded onto which a loudspeaker can be inserted. The hollow body 31 thus serves as a loudspeaker cover in the direction of the wet cell and can be formed, as a result of the great degree of freedom when molded and formed into the plastic component parts, in an optimum manner to produce better acoustics. A door latch joint 35 for retaining the door latch is likewise molded in the plastic section 2. Figure 5 shows a complete view of a support 100 of the door module with a molded plastic section 2 where the fixing points 3 for fixing the inner door panel 5 (not shown here) are arranged circumferentially in the metallic base body 1 and in section 2 of plastic. The plastic section 2 thus also serves to close the area not covered by the metallic base body 1. Figure 6 shows a complete view of a support 100 of the door module having a plastic section 2 molded on one side narrow body 1 metallic base. Also here the fixing points 3 for mounting the door module support 1 on the inner door panel 5 (not shown) are provided in the plastic section 2 and the metallic base body 1. The long degrees of the metallic base body 1 are formed in a labyrinth and have tongues 6 in which fixing points 3 have been worked or in which the fixing points 3 have been joined. The interspaces between the tabs 6 are closed with seals 20 which are preferably joined to the metal base body 1 at the same time as the plastic section 2.

As an alternative to the labyrinth-shaped configuration of the long sides, regular curves or wavy lines may also be provided as contour lines where the sections between the curves are filled when required with a seal or filler material.
