Abstract

Bow hinge (1) for connecting a tailgate to a vehicle body, characterized in that the bow hinge (1) is a U-profile (2) with a groove (5).

Description

Technical field

The invention relates to a hinge according to the preamble of claim 1 and a means according to claim 9.

State of the art

Such hinge hinges are already known and common in a variety of shapes and configurations. For example, in the DE 10 2008 045 900 A1 a tube used as a hinge.

Next is also a plastic hinge from the DE 10 2014 217 484 A1 known. However, the production of the hinge shown there is very expensive, not least because of the many undercuts in the component and the expensive tool.

In the same way is also in the EP 1 672 160 A2 a tubular element used as a bracket.

By using a tube or a tube element as a hinge, additional work is required afterwards. For example, the cables, which must be routed through the only continuous connection point between the body and the tailgate, must run through the hinge to supply the lighting or any other pantograph. In the past, the cables were attached to the surface of the pipes by means of cable ties, for example. Another solution was that the surface of the pipes had to be drilled out in order to fix cable holding clips in the holes.

The cables were not laid in the pipe, since this procedure is very labor-intensive and, in the event of a necessary exchange, being costly for the end customer.

Object of the invention

The object of the present invention is to overcome the disadvantages of the prior art. In particular, a bow hinge is to be made available in which the cable routing is simpler, cheaper and also more attractive. In addition, a weight saving with the hinge should be achieved here.

Solution of the task

The features according to claims 1 and 9 lead to the achievement of the object.

Advantageous refinements are described in the subclaims.

A bow hinge according to the invention is used to connect a tailgate to a vehicle body. Thanks to its curved shape, the bow hinge is intended to ensure sufficient mobility, particularly in the hatchback limousines.

According to the invention, the bow hinge is a U-profile. The U-profile naturally has a gutter. Corresponding cables can then be guided in this channel.

The weight saving is achieved, among other things, by designing the hinge as a stamped part. This also leads to a cost saving as a follow-on composite part or a part made by transfer tools.

In another exemplary embodiment according to the invention, the bow hinge for connecting the tailgate to the vehicle body is designed as a double-T profile with two channels.

A metal material is considered here due to the acting forces. In the prior art and also in the invention, this is steel or at least a metal material. However, the hinge according to the invention offers the possibility of a larger choice of materials, since less material is used overall and therefore a higher quality material can also be used. Overall, weight reduction is achieved here.

The hinge has a body attachment at one end. The body attachment consists of a component that enables the hinge to be connected to a parcel shelf. For this purpose, the usual bores or the like are provided in the body attachment.

At the other end, the bow hinge has a tailgate attachment. The tailgate attachment consists of a component that enables the hinge to be connected to a tailgate. For this purpose, the usual bores or the like are provided in the body attachment.

It is also provided that a U-profile plastic insert is present in the groove of the U-profile. This U-profile plastic insert has essentially the same bend as the U-profile and due to its dimensions, it can be placed in the channel with a clamp or clip.

In addition, the U-profile plastic insert can have a cable routing element. This cable routing element can be designed, for example, in the form of cable clamps, a cable duct, a cable spiral, etc.

A plastic cover element or a cover rubber strip can be provided to cover the channel. These parts form an appealing end to the U-profile and serve to provide additional protection for the installed cables.

• Ein flaches Blech wird heraus gestanzt, anschliessend wird das Blech in ein Gesenk gezogen und dadurch die U-Form erreicht. Anschließend kann ggf. ein Locharbeitsgang vorgesehen werden. Zur Verstärkung können beispielsweise Stempel oder Rippen im Gesenk vorgesehen werden, die später dann zu verstärkenden Sicken beim fertigen U-Profil führen. Dies ist gerade dort von Vorteil, wo hohe Spannungsspitzen an den Bauteilen festgestellt werden.

Protection is also claimed separately for a method for producing a U-profile with the following steps:

• A flat sheet is punched out, then the sheet is pulled into a die and the U-shape is achieved. If necessary, a punching operation can then be provided. For reinforcement, for example, stamps or ribs can be provided in the die, which later lead to reinforcing beads in the finished U-profile. This is particularly advantageous where high voltage peaks are found on the components.

embodiment

In 1 is a hinge 1 shown. The hinge 1 has a typical curved shape.

The typical curved shape of limousines and other vehicles allows a swinging tailgate to move freely.

The hinge 1 consists of the U-profile 2 that between a body mount 3 and a tailgate attachment 4 is arranged.

In addition, the U profile 2 a gutter 5 on. In the gutter 5 is a cable 14 arranged. In the prior art, instead of the U-profile 2 a bent tube is used.

This pipe then had to be drilled extensively in order to provide cable holding clips in the holes. With the cable holding clips, the cables were routed along the outside of the pipe.

This gutter 5 can, for example, serve to ensure that cables which in the prior art have been routed along the outside of the pipe now like the cable 14 in the gutter 5 can be performed.

In addition, it can also be provided that the dimensions of the channel 5 adapted a U-profile plastic insert is available, which is not shown here. This U-profile plastic insert can, for example, in turn have a cable routing element, which has the internally routed cable 10 additionally protects against wear due to abrasion. In addition, a plastic cover element can also be present.

This plastic cover can cover the gutter 5 after inserting the cable 14 seal, for example by inserting it into the U-profile plastic insert or directly into the channel 5 can be clipped on. Alternatively, a rubber cover strip can also be present, but this is also not shown here.

The 3 and 4 show simplified the process for producing a U-profile 2 ,

First, a strip of material 6 cut from another metal strip, punched out or finely cut and in a further step into a U-shaped die 10 pressed. This is done by placing a stamp 7 on a middle part 9 of the strip of material 6 ,

Then the stamp 7 in the direction of the arrow 15 pressed so that the material strip 6 shaping into the U-shaped die 10 is pressed.

Further in the die 10 , like in the 3 shown a rib 11 be provided.

In another exemplary embodiment, it can also be provided that the stamp 7 is static and the die 10 towards the stamp 7 is pressed.

In the 3 an intermediate layer is shown on another cross section. There is no rib there 11 to recognize. Here is the strip of material 6 into the die 12 been pressed so that the U-profile 2 was pressed into the channel shape and the middle part 9 in the die 10 comes to rest.

In the 4 is the U-profile 2 without die 10 shown. One is through the rib 11 a bead 12 shown. In the 4 you can see the finished U-profile 2 which is from the original strip of material 6 was formed. It consists of the middle part 9 , a first margin 7 and a second margin 8th ,

The second margin 8th protrudes at an angle of substantially 90 ° from the central part 9 of the strip of material 6 from. The first edge side protrudes in the same way 7 at an angle from substantially 90 °, with the first edge side 7 in the cross section shown, first into the bead 12 passes and then into the notification part 9 continues. This creates the gutter 5 ,

In a further step, additional work such as drilling holes can be carried out.
