Tailgate for a motor vehicle, and method for producing such a tailgate

Abstract

A tailgate, for a motor vehicle, has a main body made from an injection-molded fiber-reinforced plastics material, and at least one fiber-reinforced plastics material tape that is disposed on the main body. In order for a tailgate having improved load transmission and load distribution properties to be provided, the tailgate has at least one additional component which is at least partially embedded in the main body and which has at least one connection portion around which a loop of the fiber-reinforced plastics material tape is guided.

Claims

1. A method for producing a main body of a tailgate for a motor vehicle, wherein the method comprises steps of: attaching at least one additional component within an opened injection mold, said at least one additional component having at least one connection portion; attaching at least one fiber-reinforced plastics material tape within the opened injection mold, wherein a loop of the fiber-reinforced plastics material tape is guided around the at least one connection portion of the additional component; closing the injection mold; configuring the main body by injecting a fiber-reinforced plastics material into the closed injection mold, the at least one additional component and the fiber-reinforced plastics material tape being at least partially embedded in said main body; and incorporating at least one tailgate seal in the opened injection mold prior to the injection mold being closed.

2. The method as claimed in claim 1, wherein said injecting of the fiber-reinforced plastics material into the closed injection mold is performed using a bi-component injection molding method, wherein the fiber-reinforced plastics material is a first component of said method, and an elastomeric material for configuring a tailgate seal is a second component of the method.

3. The method as claimed in claim 2, further including incorporating at least one insulation component in the opened injection mold prior to the injection mold being closed, said at least one insulation component being at least partially embedded in the main body by injecting the fiber-reinforced plastics material into the closed injection mold.

4. The method as claimed in claim 1, further including incorporating at least one insulation component in the opened injection mold prior to the injection mold being closed, said at least one insulation component being at least partially embedded in the main body by injecting the fiber-reinforced plastics material into the closed injection mold.

5. A method for producing a main body of a tailgate for a motor vehicle, wherein the method comprises steps of: attaching at least one additional component within an opened injection mold, said at least one additional component having at least one connection portion; attaching at least one fiber-reinforced plastics material tape within the opened injection mold, wherein a loop of the fiber-reinforced plastics material tape is guided around the at least one connection portion of the additional component; closing the injection mold; configuring the main body by injecting a fiber-reinforced plastics material into the closed injection mold, the at least one additional component and the fiber-reinforced plastics material tape being at least partially embedded in said main body; and incorporating at least one insulation component in the opened injection mold prior to the injection mold being closed, said at least one insulation component being at least partially embedded in the main body by injecting the fiber-reinforced plastics material into the closed injection mold.

6. The method as claimed in claim 5, wherein said injecting of the fiber-reinforced plastics material into the closed injection mold is performed using a bi-component injection molding method, wherein the fiber-reinforced plastics material is a first component of said method, and an elastomeric material for configuring a tailgate seal is a second component of the method.

Description

BRIEF DESCRIPTION OF THE DRAWING FIGURES

(1) Further advantageous design embodiments are disclosed in the dependent claims and in the following description of the figures. In the figures:

(2) FIG. 1 shows a schematic illustration of an exemplary embodiment of a tailgate;

(3) FIG. 2 shows a schematic illustration of a further exemplary embodiment of a tailgate;

(4) FIG. 3 shows a schematic illustration of a further exemplary embodiment of a tailgate; and

(5) FIG. 4 shows a schematic illustration of a further exemplary embodiment of a tailgate.

BRIEF DESCRIPTION OF THE DRAWING FIGURES

(6) In the different figures, identical parts are always provided with the same reference signs, and so said parts are generally also described only once.

(7) FIG. 1 shows a schematic illustration of an exemplary embodiment of a tailgate 1 for a motor vehicle (not shown).

(8) The tailgate 1 has a main body 2 made from an injection-molded fiber-reinforced material. A window opening 3 for receiving a rear window (not shown) is configured on the main body 2.

(9) The tailgate 1 moreover has a fiber-reinforced plastics material tape 4 that is disposed on and/or in the main body 2. The fiber-reinforced plastics material tape 4 is disposed so as to encircle the window opening 3 and to be in an encircling peripheral region of the main body 2.

(10) The tailgate 1 furthermore has an additional component 5 which is at least in part embedded in the main body 2 and which serves for fastening a tailgate lock (not shown) to the tailgate 1, and which has two laterally disposed connection portions 6 and 7 around which in each case a loop of the fiber-reinforced plastics material tape 4 is guided. To this end, two rectangular openings or breakouts 8 and 9 through which the fiber-reinforced plastics material tape 4 is guided are configured on the additional component 5. The additional component 5 is thus a fastening component to which the tailgate lock can be fastened. The additional component 5 is partially or completely produced from a metal, a metal alloy, or a fiber-composite plastics material.

(11) FIG. 2 shows a schematic illustration of a further exemplary embodiment of a tailgate 10. The tailgate 10 differs from the exemplary embodiment shown in FIG. 1 in that three additional fiber-reinforced plastics material tapes 11, 12 and 13 are present. The two tapes 11 and 12 run in an inclined manner, intersect one another, and at the end side are connected to the plastic materials tape 4. The plastics material tape 13 runs in a horizontal manner and at the end side is connected to the plastics material tape 4. To avoid repetitions, reference is made in other respects to the above description of FIG. 1.

(12) FIG. 3 shows a schematic illustration of a further exemplary embodiment of a tailgate 14. The tailgate 14 differs from the exemplary embodiment shown in FIG. 1 in that a tailgate seal 15 is additionally disposed on the main body 2. The tailgate seal 15 can be produced conjointly with the main body in the production of the latter while using a bi-component injection molding method, or be prefabricated and be partially insert-molded with the fiber-reinforced plastics material of the main body. To avoid repetitions, reference is made in other respects to the above description of FIG. 1.

(13) FIG. 4 shows a schematic illustration of a further exemplary embodiment of a tailgate 16. The tailgate 16 differs from the exemplary embodiment shown in FIG. 3 in that an insulation component 17 for thermal and/or acoustic insulation is additionally disposed on the tailgate 16. The insulation component is at least partially embedded in the main body 2. To avoid repetitions, reference is made in other respects to the above descriptions of FIGS. 1-3.
