Description

[0001] The invention relates to a method for mounting a door hinge of a motor vehicle.

[0002] Motor vehicles typically have doors that are mounted on hinges, allowing them to pivot. These hinges are attached to a body panel and are painted along with the body during dip coating (e-coating) and other paint finishes, such as clear coating. During these painting processes, the door hangs from the hinge and is painted along with the body, resulting in a very high-quality appearance.

[0003] In contrast, modern vehicle assembly processes aim to produce the vehicle from pre-assembled large modules. This means that the door hinge cannot yet be permanently attached to the body, but only to a thin-walled side panel, which will later be attached to a larger module. However, the side panel is not structurally strong enough to withstand the door hinge and the attached door through dip coating and a subsequent painting process.

[0004] DE 10 2015 106 413 B4 discloses a door hinge for a motor vehicle which is screwed to a load-bearing body part of a motor vehicle body in a known manner, whereby the resulting problem in vehicle manufacturing using large modules is not taken into account in any way.

[0005] DE 28 54 530 A1 discloses a hinge for doors or flaps on motor vehicles, consisting of two hinge main parts pivotably connected to each other via a joint, one of which is designed as a base plate that can be fixed to the vehicle body and the other as a pivoting part to be attached to the movable door or flap, wherein an auxiliary plate is provided below the base plate which is coupled to it via a connecting joint, with which the hinge can be fixed to the vehicle body without fixing the base plate.

[0006] DE 43 21 752 C1 discloses a hinge part-wall composite with a hinge receptacle, a hinge part connected thereto, wherein the hinge receptacle has a web which engages in an opening.

[0007] The task is to specify a method for assembling a door hinge of a motor vehicle, which can also be used in vehicle assembly using large modules.

[0008] It is also advantageous if the large modules still have a closed outer side panel, which is designed as a classic outer side panel, for example with an A-pillar, a sill, a rear wheel arch and / or a roof frame strip.

[0009] The problem of the method is solved by the features of claim 1.

[0010] One embodiment of the invention relates to a method for mounting a door hinge of a motor vehicle, comprising the steps of: - Providing a side panel, hereinafter also referred to as "outer side panel", of a motor vehicle, - Providing a first door hinge part, to be mounted on the body side, together with a second door hinge part, to be mounted on the door side, - Positioning the first door hinge part on the outer side panel and pre-fixing the first door hinge part to the outer side panel, - Providing an auxiliary bracket for the stable connection of the first door hinge part to the outer side panel, - Connecting the auxiliary bracket to the first door hinge part on the outer side panel, - Connecting the door to the first door hinge part using the second door hinge part, - Painting the exterior side panel and the door in one painting process, - Removal of the door and the second door hinge part, - Removing the auxiliary bracket, - Providing a structural module, in particular the body structure or a large module, - Connecting the painted outer side panel to the first door hinge part with the structural module, - Hitting the door with the second door hinge part against the first door hinge part.

[0011] The auxiliary support can preferably also be a part, preferably a part of the device, that stabilizes the outer side panel through the subsequent cathodic dip coating.

[0012] It is also preferred if, after removing the auxiliary bracket, the hinge is securely fixed to the outside of the side panel.

[0013] This allows a door hinge to be attached to a structurally weaker exterior side panel and painted along with the door without any expected visual drawbacks. The exterior side panel can then be attached to a larger module or similar structure at a later date.

[0014] In one embodiment, it is advantageous if the coating is applied by cathodic dip coating and / or by another type of coating, such as clear lacquer. This allows for the application of a high-quality coating even to larger components or to several components simultaneously.

[0015] It is particularly advantageous if the pre-fixing is done using screw elements, such as screws, countersunk screws, grub screws, etc. This allows for secure pre-fixing, which also permits a certain degree of adjustment of the components.

[0016] It is also advisable to connect the auxiliary bracket to the first door hinge component on the outer side panel using fastening bolts, such as threaded bolts or clamping bolts. This ensures a secure connection that can also be safely removed.

[0017] It is also advantageous if the first door hinge component has threaded holes for screwing in the mounting bolts or threaded bolts of the auxiliary bracket. This ensures a secure connection that can also be safely removed.

[0018] It is also advantageous if the outer side panel is positioned between the first door hinge component and the auxiliary bracket. This ensures secure integration of the outer side panel.

[0019] It is also advantageous if the structural module is connected to the first door hinge part and the outer side panel using screw elements, such as screws. This ensures a secure connection.

[0020] It is also advisable to position the outer side panel between the first door hinge component and the structural module. This ensures secure attachment to the outer side panel.

[0021] It is also advantageous to pass the screw elements through the holes in the first door hinge component and screw them into threaded holes in the structural module. This achieves a design that utilizes the threaded holes multiple times, saving installation space and costs.

[0022] The invention will now be explained in detail using an exemplary embodiment and with reference to the drawings. The drawings show: Fig. 1 a schematic view of an embodiment of a door hinge to illustrate the method according to the invention, Fig. 2 a further schematic view of an embodiment of a door hinge to illustrate the method according to the invention, Fig. 3 a further schematic view of an embodiment of a door hinge to illustrate the method according to the invention, Fig. 4 a further schematic view of an embodiment of a door hinge to illustrate the method according to the invention, Fig. 5 a further schematic view of an embodiment of a door hinge to illustrate the method according to the invention, and Fig. 6 a further schematic view of an embodiment of a door hinge to illustrate the method according to the invention.
