Technical Field

The invention relates to a fastening device for fastening a first component to a second component, in particular for fastening two body shell modules in the manufacture of motor vehicles. The invention also relates to a component assembly comprising a first component and a second component and such a fastening device.

Background

In the case of conventional vehicle bodies, fixed body shell connection techniques, such as welding or gluing and riveting, are used to connect the main modules of the vehicle body, such as the front, cabin and rear modules, to one another. For example, a screw solution, such as may be used for fastening a front end module, may be implemented using a complex, component-specific bracket as an auxiliary device.

Thus, it is time-consuming and expensive to construct a sufficiently secure connection in the body shell. Heretofore, the use of joints has been limited to the formation of specific regions of the vehicle body or certain joints.

For example, DE 10329017 a1 discloses a support structure, in particular a vehicle superstructure for a vehicle, made of interconnected profile parts, with substantially rectangular hollow profiles which are connected by a non-thermal joining connection at least one joint, wherein the joining connection is a flat adhesive connection, and wherein the profile parts lie directly against one another and are shaped to form a flat adhesive surface and correspond to one another at least at the joint, by means of which the profile parts can be adhered to one another directly or indirectly, so that a cross-sectional mechanical torque support is produced between the profile parts connected by adhesive bonding at the joint.

Disclosure of Invention

The problem addressed by the present invention is to provide a fastening device for fastening a first component to a second component, which fastening device facilitates a sufficiently secure fastening, for example for fastening two body shell modules in the manufacture of motor vehicles, but can be produced in a particularly cost-effective manner. The problem addressed by the present invention is also to provide a component assembly comprising a first component and a second component and such a cost-effective and efficient fastening device for fastening the first component to the second component.

This problem is solved by a fastening device for fastening a first component to a second component, in particular for fastening two body shell modules in the manufacture of motor vehicles, comprising a first connecting piece and a second connecting piece, wherein the first connecting piece and the second connecting piece each comprise: the component fastening surface, the connector fastening surface perpendicular to the component fastening surface, and at least one, and preferably two, lateral reinforcing surfaces, each connecting a lateral end edge of the component fastening surface to a lateral end edge of the connector fastening surface, wherein the component fastening surface of the first connector is fastened to the first component, wherein the component fastening surface of the second connector is fastened to the second component, wherein the connector fastening surface of the first connector is fastened to the connector fastening surface of the second connector.

According to the invention, two adapter holders are provided, namely a first and a second connecting piece, which have a very simple design and interact with each other in order to fasten the components to each other. The connecting element can be used in different positions in the vehicle, in particular for the longitudinal connection of two profile parts or profile ends of a module. Due to its simple design, the connecting piece can be produced as a universal component in a cost-effective manner.

The invention means that during the manufacture of a motor vehicle, smaller prefabricated modules can be assembled later in the assembly process, without having to go through the entire process chain; for example, only after the spray process.

This can be easily and economically achieved for modules connected by the fastening device according to the invention if the individual modules have to be replaced after the manufacture of the vehicle, either because of the need for maintenance or at the request of the customer.

The attachment can be used in such a way that it is first screwed in the X-direction of the vehicle with the attachment fastening surface, tolerance compensation being possible in the Y-and Z-direction of the vehicle.

The component fastening surface of the first connection member is preferably screwed and/or riveted and/or welded and/or glued to the first component, and/or the component fastening surface of the second connection member is screwed and/or riveted and/or welded and/or glued to the second component. These surfaces may also be mechanically, thermally or chemically connected in other ways known in the art. However, it is particularly preferred that the surface is screwed down and can therefore also be subsequently disassembled. In another embodiment, the surface is glued and tightened, for example by flow drill threading (FDS), in other words by means of flow drill screws.

The connector fastening surface of the first connector is preferably screwed and/or riveted and/or welded and/or glued to the connector fastening surface of the second connector. As previously described for the component fastening surfaces, the connector fastening surfaces may also be mechanically, thermally or chemically connected in other ways known in the art. However, it is particularly preferred that the surface is screwed or glued and screwed, for example flow drill threads (FDS), in other words by means of flow drill screws.

The connector fastening surface of the first connector is preferably threaded to the connector fastening surface of the second connector such that the head of the screw is adjacent the connector fastening surface of the first connector and the end surface of the nut is adjacent the connector fastening surface of the second connector. In this case, the screw is screwed into the nut such that the two connector fastening surfaces are sandwiched between the head of the screw and the nut. Alternatively or additionally, flow drill screws, which typically do not have nuts, may also be used.

The reinforcing surface is preferably triangular. The end edge of the reinforcement surface may extend from an end of the end edge of the component fastening surface to an end of the end edge of the connector fastening surface.

The reinforcement surfaces are preferably perpendicular to the component fastening surface and the connector fastening surface, respectively.

The first and second connectors preferably each have an extension surface, wherein the extension surface substantially forms an extension of the fastener fastening surface that extends beyond the component fastening surface of the connector such that the extension surface is located between the first component and the second component when the connector is in use.

The first and second connectors preferably take the shape of a common component.

The component assembly according to the invention may comprise a first component and a second component, in particular a first and a second body shell module of a motor vehicle, and at least one fastening device as described above, wherein the component fastening surface of the first attachment is fastened to the first component, wherein the component fastening face of the second attachment is fastened to the second component, wherein the attachment fastening surface of the first attachment is fastened to the attachment fastening surface of the second attachment. In this manner, the first and second components are ultimately fastened or connected to one another.

If desired, the extension surface is preferably located between the first and second components. In particular, the extension surface may be sandwiched between an end face of the first component and an end face of the second component. By means of the extension surfaces, the two parts can be positioned axially to each other.

Preferably, at least two fastening means are arranged opposite each other such that the fastening surfaces of opposite connectors face each other, wherein the first and second parts are arranged between the fastening surfaces of the connectors located opposite each other.

Preferably, at least two or more fastening means are arranged side by side, in particular such that the lateral reinforcement surfaces of two connectors are each adjacent to each other. A plurality of connecting elements, in particular those designed as universal parts, can thus be used in combination with one another, arranged alongside one another, in order to form a particularly secure connection.

Detailed Description

In fig. 1-7 a component assembly according to the invention is shown, which comprises three fastening means side by side on each of two opposite sides of the component assembly, in other words a total of six fastening means.

The component assembly comprises a first component 1, i.e. a rectangular profile of a motor vehicle body shell, and a second component 2, i.e. a rectangular profile of the same design of another body shell component. According to the invention, the two parts 1,2 are fastened to each other indirectly by means of a triangular connection 3, 4. For this purpose, in each case two connecting elements, namely the first connecting element 3 and the second connecting element 4, are first fastened to the respective component and then to one another. Such two connectors 3,4 together form a fastening means for fastening the first component 1 to the second component 2.

The first and second connecting members 3,4 each comprise: a component fastening surface 5, a connector fastening surface 6 perpendicular to the component fastening surface 5, and two lateral reinforcement surfaces 7, each lateral reinforcement surface 7 connecting a lateral end edge of the component fastening surface 5 to a lateral end edge 9 of the connector fastening surface 6 (see in particular fig. 1).

The reinforcing surfaces 7 are each triangular in shape and are each perpendicular to the component fastening surface 5 and the connector fastening surface 6. Thus, the connecting members 3,4 have a substantially triangular shape, seen from the side.

The component fastening surface 5 of the first connecting piece 3 is fastened to the first component 1; the component fastening surface 5 of the second connector 4 is fastened to the second component 2.

The connector fastening surface 6 of the first connector 3 is fastened to the connector fastening surface 6 of the second connector 4.

In particular, the component fastening surface 5 is screwed onto the respective component 1,2, preferably by means of a flow drill screw. These fastening surfaces are preferably additionally glued.

The connector fastening surfaces 6 are each screwed to each other-see in particular fig. 5 and 7. The connector fastening surface 6 of the first connector 3 is screwed to the connector fastening surface 6 of the second connector 4, wherein the head 10 of the screw 11 is adjacent to the connector fastening surface 6 of the first connector 3 and the end face of the nut 12 is adjacent to the connector fastening surface 6 of the second connector 4. In particular, a press-in screw can be used as the screw 11 in order to represent, together with the nut 12, a detachable connection of the connector fastening surface 6.

As can be clearly seen in all the figures, for example in fig. 6 and 7, the first and second connectors 3,4 each have an extension surface 13 in addition to their triangular shape, wherein the extension surfaces 13 substantially form an extension of the connector fastening surface 6, which extends beyond the component fastening surface 5 of the connectors 3, 4. The extension surfaces 13 of the connectors 3,4 are arranged between the first and second parts 1,2, respectively, so that an end abutment for the profiles or parts 1,2 is formed by the extension 13. In each case, the extension surface 13 is sandwiched between an end face of the first component 1 and an end face of the second component 2. Thus, the extension surface 13 also creates a fixed distance between the parts 1 and 2.

As can be clearly seen in fig. 1, for example, three fastening devices are first arranged side by side so that the lateral reinforcing surfaces 7 of the two connecting pieces 3,4 are placed side by side with each other. In the embodiment according to fig. 1, the connecting elements 3,4 thus cover the entire height of the parts 1, 2.

Furthermore, the two fastening devices are arranged opposite each other in each case (see, for example, fig. 1 and 2) such that the fastening surfaces 5 of the opposite connecting pieces 3,4 face each other, wherein the first and second components 1,2 are arranged between the fastening surfaces 5 of the connecting pieces 3,4 located opposite each other. Over the entire height of the profiles or parts 1,2, the fastening means are in each case arranged opposite one another, or in each case therefore the first connecting piece 3 is arranged opposite the first connecting piece 3 and the second connecting piece 4 is arranged opposite the second connecting piece 4, so that the profiles 1,2 are fastened, in particular screwed, flow-drilled screwed and/or glued in each case between the fastening surfaces 5 of the first or second connecting pieces.

All first and second connecting elements 3,4 used are designed as common parts 14 (see fig. 2), and can therefore be produced particularly efficiently and economically.
