Summary of the invention

[0006] The object of the present invention is to provide a positioning device, a vehicle articulation structure and a method which are reliable, safe and cost-effective.

[0007] According to the invention, this object is achieved by a positioning device having the features of claim 1 and correspondingly by a vehicle articulation arrangement having the features of claim 9 and by a method having the features of claim 12 .

[0008] According to one aspect of the invention, a positioning device is created for temporary connection to an articulated structure having an axis of rotation. The positioning device comprises a retainer assigned to an articulated part of the articulated structure, the positioning device comprising a curved strip hole and an eyelet concentric with the axis of rotation, wherein the eyelet has a periphery for receiving a bolt defining the axis of rotation, wherein the retainer is configured to be removable from the articulated structure and has an integral part facing a first side of the articulated part. The positioning device is characterized in that at least one protrusion extends from the first side, the at least one protrusion being arranged directly adjacent to the periphery of the eyelet. Advantageously, the at least one protrusion increases the friction between the articulated part and the retainer, so that the retainer is at least frictionally arranged on the articulated part, wherein the retainer advantageously comprises an integrated anti-twist protection structure.

[0009] At least one projection expediently has a wall which at least partially prolongs the periphery of the eyelet in axial direction. Advantageously, the contact surface between a bolt which can be inserted into the eyelet and the periphery of the eyelet is increased, thereby making displacement of the retainer about the horizontal axis more difficult.

[0010] Advantageously, the holder has more than two projections, wherein the projections are arranged along a circle, wherein the projections are evenly spaced apart from one another, wherein the projections and the first side are arranged perpendicular to one another and wherein the height of each projection parallel to the axis of rotation is 0.1 mm to 1.0 mm, preferably 0.2 mm to 0.6 mm, particularly preferably 0.5 mm. Advantageously, all projections have the same height so that the holder lies flat on the hinge or counterpart. Furthermore, due to the presence of a plurality of projections, the friction forces are advantageously increased so that the holder cannot perform any unwanted displacements.

[0011] The first side with at least one protrusion is preferably at least partially configured as a stamp for deforming the at least mostly closed annular surface of the counter material part. Advantageously, the protrusions are suitable as an embossing tool for pressing impressions into a mating part having a softer material than the retainer so that the retainer is locked in the mating part in a frictional and form-fitting manner.

[0012] The strip-shaped hole has at least one cross-sectional constriction, wherein at least one holding position is defined in the strip-shaped hole and at least one perforation is arranged between the strip-shaped hole and the eyelet. Advantageously, at least one stop position is defined by the constriction in order to hold the door in an open stop position during the painting process. Furthermore, the constriction is advantageously designed to be elastic by the perforation, so that above a certain force the constriction is widened and the stop pin can be moved further in the strip-shaped hole, so that the door can be closed and opened again.

[0013] According to a preferred embodiment, the holder is configured as a flat body having a second side opposite to the first side, the second side facing away from the hinge, wherein the first side and the second side are arranged parallel to each other, and the first side and the second side are at least partially connected to each other via a peripheral lateral area. The holder is flat and compact, with a height of about 2 mm to 6 mm, the holder is lightweight, and the holder is stackable.

[0014] The retainer is preferably configured as a stamped part made of sheet metal, in particular heat-treated steel. In order to obtain a certain hardness and durability of the retainer, the retainer is preferably made of heat-treated steel, such as C45E or 58CrV4, wherein the hardness of the retainer is between 56 and 62 HRC. In addition, the retainer can be easily and economically manufactured using a stamping process, thereby saving time and cost.

[0015] A positioning device is preferably provided to fix the door of the vehicle in at least one preferred opening position during the painting process. Advantageously, the retainer is used during the painting process of the body-in-white of the vehicle to hold the flap in the desired opening position so that the body-in-white can be completely painted. Furthermore, the retainer can advantageously be reused for further painting processes of other vehicle bodies, thereby saving costs.

[0016] According to one aspect of the present invention, a vehicle articulation structure is created. The vehicle articulation structure comprises a first articulation that can be attached to one of the vehicle body and the door, and a second articulation that can be attached to the other of the vehicle body and the door, and a bolt that is connected to one of the first articulation and the second articulation in a non-rotatable manner, wherein the other of the first articulation and the second articulation can pivot relative to the one of the first articulation and the second articulation about the rotation axis of the bolt, wherein the other of the first articulation and the second articulation comprises at least one cantilever arranged with an opening, wherein a stop pin is arranged on the surface of the cantilever. The vehicle articulation structure is characterized in that it comprises a positioning device according to one of the above characteristics, the at least one protrusion is connected to one of the first articulation and the second articulation in a non-rotatable manner, and the stop pin is movably accommodated in the strip hole. Advantageously, by this arrangement, the retainer is always kept in a defined position, so that the pin moves in the strip hole only when the door of the vehicle is opened or closed. In this way, the pin and retainer can be used to provide a defined opening position for the door of the vehicle, which is necessary for the painting process.

[0017] One of the first hinge and the second hinge expediently comprises an axial bearing with a tapered outer surface, wherein the opening is configured as a tapered opening which matches the tapered outer surface and is connected to the tapered outer surface in an articulated manner. The first hinge and the second hinge are advantageously connected to each other in an articulated manner. Here, both hinges have tapered connecting elements which match each other, which advantageously simplifies the assembly of the door of the vehicle with the body.

[0018] The axial bearing with a conical outer surface preferably comprises a bore having at least partially an internal thread, into which a bolt having an external thread is screwed in such a way that the shaft of the bolt passes through the eyelet of the retainer, and the area assigned to the head of the bolt, which extends radially outside the eyelet, couples the axial bearing and the retainer in a non-rotatable manner. In this case, the retainer is connected to the bearing by means of the bolt in a force-locking manner by means of surface pressure. On the other hand, the projection of the retainer is pressed into the bearing, so that the bearing is at least partially plastically deformed by the projection to form a recess, in which the projection is arranged, so that a form-fitting connection is produced between the retainer and the bearing. Advantageously, the retainer is clamped in a sandwich-like manner between the head of the bolt or the washer and the hinge, wherein the connection is advantageously a threaded connection that can be easily loosened to remove the retainer after the painting process.

[0019] According to one aspect of the invention, a method for temporarily connecting a positioning device to a vehicle articulated structure is created. The method comprises the following steps: arranging the eyelet of the retainer of the positioning device concentrically with the borehole of the support portion of the hinge of the vehicle articulated structure; passing the bolt through the eyelet and the borehole and connecting the bolt to the support portion in a detachable manner; and applying a pre-adjustable force to the bolt to temporarily couple the retainer to the support portion in a non-rotatable manner. Advantageously, the retainer can be simply attached to the articulated structure when the door of the vehicle is already mounted on the body. In addition, the retainer can be advantageously removed by means of a threaded connection without the need to remove the door of the vehicle from the body, thereby saving time and costs.

[0020] The bore of the support part advantageously has an internal thread, wherein the bolt has an external thread that matches the internal thread of the bore of the support part and the bolt can be connected to the support part of the hinge by applying a torque between 10Nm and 40Nm, preferably between 15Nm and 35Nm, particularly preferably 30Nm. Advantageously, the bolt can be simply screwed in using a torque wrench with a specified tightening torque.

[0021] The retainer suitably comprises at least one projection which penetrates into at least one material portion of the support of the hinge, and the at least one material portion of the support is plastically deformed by the at least one projection of the retainer. Under a certain tightening torque, the retainer is pressed together with the relative hinge so that the projection is pressed into the soft material, thereby forming a connection with friction and form fit between the retainer and the hinge. In this case, the retainer is connected to the support in a force-locking manner by means of bolts by means of surface pressure. On the other hand, the projection of the retainer is pressed into the support, so that the support is at least partially plastically deformed by the projection to form a recess, in which the projection is arranged, thereby producing a form-fit connection between the retainer and the support.

[0022] The method preferably comprises configuring the retainer of the positioning device and / or the vehicle articulation structure according to one of the above features. Preferably, the method is applied with the aid of the positioning device of the invention and the vehicle articulation structure of the invention.

The vehicle articulated structure 10 comprises a first articulated part 20 attachable to a vehicle body K and a second articulated part 30 attachable to a door T of the vehicle, wherein the vehicle body K and the door T are both indicated by dotted lines.

[0033] The first hinge 20 includes a fastening portion 21 having a first plane 21a, in which a mounting hole 22 is arranged, for connecting the first hinge 20 to the vehicle body K, for example, by riveting and / or screwing. In addition, the first hinge 20 includes a cantilever 23 having a second plane 23a, wherein the first plane 21a of the fastening portion 21 is perpendicular to the second plane 23a of the cantilever 23. The first hinge 20 also includes an axial support portion 24 having a tapered outer surface 25, wherein the support portion 24 is configured as a truncated cone, wherein the support portion 24 is arranged on the cantilever 23 of the first hinge 20, wherein the support portion 24 extends from the cantilever 23 of the first hinge 20 in a direction away from the fastening portion 21 of the first hinge 21. The support portion 24 includes a material portion 27 having an annular surface 27a, which faces away from the cantilever 23 of the first hinge 20. Further, the annular surface 27a is arranged parallel to the second plane 23a. The support 24 further comprises a cylindrical bore 26 with an internal thread 26a along the axial axis for receiving a bolt 50 with a cylindrical shaft 51 having a cooperating external thread 51a. Furthermore, the bolt has a tool attachment 54 configured as a hexagonal head.

[0034] The second hinge 30 includes a fastening portion 31 having a first plane 31a, in which two mounting holes 32 are arranged, for connecting the second hinge 30 to the door T, for example, by riveting and / or screwing. In addition, the second hinge 30 includes a cantilever 33 having a second plane 33a, wherein the first plane 31a of the fastening portion 31 is perpendicular to the second plane 33a of the cantilever 33 of the second hinge 30. In addition, the cantilever 33 of the second hinge 30 includes an opening 34, which is configured as a tapered opening 34a, in which a tapered bushing 35 is arranged. The second hinge 30 also includes an axial cylindrical stop pin 60, which is arranged on the cantilever 33 of the second hinge 30, and the stop pin 60 extends from the cantilever 33 of the second hinge 30 in a direction away from the second plane 33a of the cantilever 33 of the second hinge 30.

[0035] Furthermore, a holder 40 defining the positioning device 1 is shown, which has a lower first side 43 facing the hinge structure 10 and an opposite upper second side 44. The holder 40 is manufactured as a flat piece from sheet metal, wherein the holder 40 is produced by a stamping process and the material of the holder 40 is a hardened and tempered steel with increased hardness. The first side 43 and the second side 44 are formed flat and parallel, wherein the first side 43 and the opposite second side 44 are connected together by an outer peripheral lateral area 48, and the lower first side 43 of the holder 40 faces the cantilever 33 of the hinge 30. The holder 40 also includes a cylindrical eyelet 42 with an inner peripheral edge 42a, wherein the eyelet is surrounded by a flat material ring 49. Furthermore, the holder 40 includes a curved strip hole 41, which has a constriction 41a that can be locked by a stop pin 60, and the stop pin 60 can be slidably displaced in the strip hole 41 after the constriction. A through hole 47 is arranged between the strip hole 41 and the eyelet 42 so that the contraction portion 41 a can be elastically deformed. In addition, the inner diameter of the eyelet 42 is slightly larger than the outer diameter of the shaft 51 of the bolt 50 .

[0036] Figure 2 Shown from the bottom Figure 1 , wherein the lower first side 43 of the holder 40 is visible, the three protrusions 45 being arranged offset from one another and adjacent to the eyelet 42 of the holder 40. Furthermore, the fixing portion 60a of the stop pin 60 can be seen, wherein the stop pin 60 is riveted to the cantilever 33 of the second hinge 30. Furthermore, the fixing portion 24a of the support 24 can be seen, wherein the support 24 is riveted to the cantilever 23 of the first hinge 20.

[0037] Figure 3A bottom view of the lower first side 43 of the retainer 40 is shown, wherein the arrangement of three protrusions 45 is shown. The three protrusions 45 are arranged adjacent to the inner periphery 42a of the eyelet 42, wherein a wall 45a of each protrusion 45 is configured to be flush with the periphery 42a and partially extend the periphery 42a. In addition, the protrusions 45 are arranged along concentric circles 46 relative to the eyelet 42, and adjacent protrusions 45 surround a common angle of about 120°. Here, the concentric circles 46 are shown as dotted lines. The protrusions 45 have a substantially rectangular cross-sectional shape, wherein only the wall 45a of the periphery 42a corresponding to the circle 46 of each protrusion 45 is curved, and the edges of the protrusions 45 are all sharp. In the present embodiment example, the height of the protrusions 45 is correspondingly 0.5mm, wherein the height of the protrusions 45 is defined as the length extending outward from the lower first side 43. Therefore, the lower first side 43 corresponds to the base surface of each protrusion 45.

[0038] Figure 4 A perspective view of an assembled vehicle articulation structure 10 is shown, wherein a retainer 40 is attached to a first articulation 20. Here, the first articulation 20 is rigidly connected to the vehicle body K, the retainer 40 being pressed onto the first articulation 20 by means of a bolt 50 or its region 52, so that the retainer 40 and the first articulation 20 are connected to each other in a non-rotatable manner. When the door T to which the second articulation 30 is attached is opened, the stop pin 60 in the strip hole 41 of the retainer 40 is displaced so that the maximum door opening is predetermined by the strip hole 41 of the retainer 40. Furthermore, the door T is held in the open position as long as the pin 60 has passed through the constriction 41a of the strip hole 41 of the retainer 40. Thus, the second articulation 30 is pivotably connected to the first articulation 20 and pivotably arranged relative to the retainer 40, wherein the strip hole 41 of the retainer 40 provides a defined opening angle of the door T via the stop pin 60.

[0039] Figure 5 Shows Figure 4 FIG. 1 is a top view of the assembled vehicle articulated structure 10 , with a first section line VI-VI and a second section line VII-VII.

[0040] Figure 6 Shows Figure 5, which shows the threaded connection between the bolt 50 and the support part 24 of the first articulated structural component 20 with the tapered outer surface 25. It can also be seen that one protrusion 45 of the retainer 40 is pressed into the front side of the material part 27 of the annular surface 27a of the support part 24, providing a frictional and form-fitting connection between the retainer 40 and the first hinge 20. As a result, all protrusions 45 are uniformly pressed into the softer material part 27 of the support part 24 of the first articulated structural component 20 by the contact force of the area 52 of the bolt 50, so that the support part 24 is plastically deformed.

[0041] A bushing 35 is arranged between the support 24 and the opening 34a of the second hinge 30 to facilitate the pivotal displacement of the second hinge 30, wherein the bushing 35 is mutually compatible with the tapered outer surface 25 of the support 24 of the first hinge 20 and the tapered opening 34a of the second hinge 30. Furthermore, the rotation axis A is clearly identifiable, about which the second hinge 30 can be rotationally displaced.

[0042] Furthermore, it can be clearly recognized that the retainer 40 is arranged with its first side 43 spaced apart from the second hinge 30, so that when the second hinge 30 moves, no undesirable grinding and / or braking effect of the retainer 40 and the cantilever 33 of the second hinge 30 occurs, wherein the gap dimension 36 is approximately equal to the thickness of the bushing 35. Furthermore, the first hinge 20 is also spaced apart from the second hinge 30, with a gap dimension 36 approximately equal to the thickness of the bushing 35, so that no undesirable braking effect occurs during the pivoting of the second hinge 30.

[0043] Figure 7 Shown from Figure 5 VII-VII of the second sectional view, wherein the locking pin 60 can be seen as being riveted with its fixing portion 60a to the cantilever 33 of the second hinge part 30, wherein the cantilever 33 has a bore 33b in which the locking pin 60 is arranged. In addition, the locking pin 60 has a collar 60b which adjoins the second plane 33a of the cantilever 33 of the second hinge part 30.

[0044] The working principle of the present invention is as follows:

[0045] First, the eyelet 42 of the retainer 40 is arranged concentrically with respect to the bore 26 of the support portion 24 of the first hinge structure member 20, and the protrusion 45 of the first side 43 of the retainer 40 faces the support portion 24, more specifically, the annular surface 27a of the support portion 24. Then, the retainer 40 is set on the support portion using the protrusion 45, and the stop pin 60 will be received in the strip-shaped hole 41.

[0046] Then, a bolt 50 with an external thread 51a is inserted into the eyelet 42 and screwed into the bore 26 of the support 24. The screw connection is preferably carried out using a torque wrench with a tightening torque of 30 Nm. Thus, there is a releasable screw connection between the retainer 40 and the support 24, the bolt 50 pressing on the retainer 40, so that the protrusion 45 of the retainer 40 is pressed into the softer support 24. In this case, the retainer 40 is connected to the support 24 in a force-locking manner by means of the surface pressure via the bolt 50. On the other hand, the protrusion 45 of the retainer 40 is pressed into the supporting portion 24 like an embossing mold, so that the supporting portion 24 is at least partially plastically deformed by the protrusion 45, and the protrusion 45 produces a recess in the supporting portion 24, and the protrusion 45 of the retainer 40 is arranged in the recess, thereby producing a shape-fitting connection between the retainer 40 and the supporting portion 24 of the first hinge 20, so that the retainer 40 is attached to the supporting portion 24 of the first hinge 20 in a non-rotatable manner with anti-slip traction.

[0047] In order to remove the retainer 40 after a successful painting operation, the bolt 50 is screwed in the opposite direction, for example by means of an open-end wrench, and removed from the bore 26 of the first articulated part and the eyelet 42 of the retainer 40. Thus, the retainer 40 can be immediately removed from the vehicle articulated structure 10, the bolt 50 can be inserted again into the bore 26 of the first articulated part 20 and screwed onto the first articulated part 20 and the second articulated part 30, thereby obtaining a complete vehicle articulated structure 10, wherein the retainer 40 can be reused for further work processes, thus saving material and costs.
