Description

Releasable connection for a space-saving fastening element by means of a latching element
Technical Field
The invention relates to a detent element (detent) for producing a detachable detent connection between a first component and a second component.
Background
A system for connecting structures on thin-walled plastic shells, covers and panels is known from the publication https: 12/16/2002// www.kunststoffe.de/produkte/uebersicht/beitrace/snap-mini-loesbare-verbindngen-578275. html. The system can be used in any position involving the installation of a fixing element (BefestigungSement) that can be reopened at any time in a relatively small space. These include, for example, computer housings, cell phone half shells, panel fixtures, base stations, wireless telephones, panels, and covers, as well as in the automotive (Kfz) field. The connection of the fastening element to the thin-walled component is of great importance here. The connecting element is thus joined in a friction welding or ultrasonic welding manner to the centering aid material of the component. This method presupposes that the fastening element and the component are composed of the same or different weldable thermoplastics.
EP 1160071 a2 describes a friction welding method for rod-shaped threaded elements. A rod-shaped threaded element is first fixed in a friction-welded sleeve by its outer thread. The friction welding sleeve is then rotated over the rod-shaped threaded element and fixed in the bore by friction welding. The hole is provided in the stationary stem as an opening in the component or as a recess in the component. Since, according to patent document EP 1160071 a2, the torque for friction welding is transmitted from the rod-shaped threaded element to the friction-welded sleeve, this mechanical load weakens the connection between the rod-shaped threaded element and the friction-welded sleeve. This has a negative effect on the connection to be produced ultimately between the rod-shaped threaded element and the component.
WO 2014/124841 a1 discloses an improved friction welding element which can be fixed in a bore of a housing by means of friction welding. The friction welding element has a connecting sleeve with a radially inner side and a friction welding jacket formed on the radially outer side of the connecting sleeve. The friction-welded housing comprises a radially outer friction-welded contour for a joint-like connection to the housing material, which comprises at least one conically shaped step in the axial direction and a flange arranged on the outer circumference, which is arranged axially adjacent to the end of the connecting sleeve and has at least one drive means or coupling means for rotating the friction-welded element on the upper side of the flange facing away from the friction-welded contour.

Detailed Description
For purposes of this description, an "-x" of an x-axis (reference axis) in the horizontal line shall denote a customary direction of travel of the vehicle forward, and a "+ x" of the x-axis in the horizontal line shall denote a rearward direction opposite the customary direction of travel of the vehicle. In the following description, the x-axis is transferred analogously to a component on the vehicle, for example a lighting element arranged on the vehicle.
The y-direction and z-direction are defined as follows based on the reference axis:
"y" represents a direction transverse to the x-direction in the horizontal line. "+ y" represents a horizontal lateral direction from zero on the x-axis to the right, and "-y" represents a horizontal lateral direction from the reference axis to the left.
"z" represents the direction in the vertical line transverse to the x-direction. "+ z" represents a vertical cross direction from zero on the x-axis upward, and "-z" represents a vertical cross direction from the x-axis downward.
Fig. 1 shows a section a-a in the x/y plane through a component 20 which is detachably fastened to the holder 10 and which is detachably engaged in the holder 10 by means of a conventional detent element 30 which is equipped on one side as a detent section 31 with a ball arranged on the end side of the detent element 30 and which is screwed on the other side from the outside into a receiving opening 22.21 of the housing structure 22 of the component 20 by means of a form-fitting connection of the end of a fastening element of the detent element, which is opposite the detent section 31 and is designed in the form of a screw external thread 32.
The latching element 30 with the spherical latching section 31 arranged on the generally cylindrical pin, together with the transition element 33, is referred to as a ball stud (Kugelzapfen)31, in the sense that in the present invention a detachable connection by means of the latching element 30 with the ball stud 31, 33 for the space-saving fastening of the component is meant.
The balls or ball head pins 31, 33 with the balls on the end sides thus form a coupling structure known as a simple principle of plug connection. This plug connection forms a vibration decoupling at the same time as an optimum fit. For this purpose, a ball seat, which is referred to below as a sleeve cushion or cushion ring 40 (see all the figures), in which the locking section 31 can be locked, is provided in the holder 10 in the coupling structure. The plug-in sleeve insert 40 is mounted in the opening 11 provided for this purpose on the underside of the respective holder 10 and is held therein in a form-fitting manner. The ball pins 31, 33 and thus the latching elements 30 can be screwed, glued or clipped to the respective component 20 to be fastened, depending on the embodiment. The component 20 to be fastened is assembled by simply inserting the balls 31 (detent segments) of the ball pins 31, 33 (detent elements) and is disassembled by pulling out the ball pins 31, 33.
According to section a-a, the observer views in top view an x/y plane which, in a vehicle which is not shown in detail, is parallel to the lane plane.
The illustrated holder 10 is designed as a vehicle-side body part and comprises a holder region with an opening 11 that is not visible from the outside. A sleeve insert 40, which has an inner contour corresponding to the outer contour of the locking section 31 with the ball, engages in the opening 11.
The member 20 which can be reversibly put into an assembled state with the holder 10 is a lighting element.
In the partial view of the lighting element 20 shown in fig. 1, a portion of the translucent cover glass 21 and a portion of the housing-like structure of the lighting element 20 are shown, wherein in the upper region the connection point V between the housing structure 22 and the cover glass 21 is shown.
The housing structure 22 comprises a first structural region 22.1, by means of which a connection between the housing structure 22 and the cover glass 21 is produced (see connection point V).
The housing structure 22 comprises a second structural region 22.2, which is designed in such a way that the latching elements 30; 30.1can be connected to the second structural region 22.2.
The housing structure 22 comprises a third structural region 22.3, which is connected to the second structural region 22.2 and forms the other part of the housing of the lighting element 20.
The housing structure 22 comprises a fourth structural region 22.4, which is arranged as a covering or design covering in the installation space of the lighting element 20.
In addition to the locking section 31, the locking element 30 also comprises a transition element 33, which is designed, for example, as a cylindrical pin and has a fastening element 32 as a screw thread 32, wherein the transition element 33 has an external polygonal structure 33.1, on which a tool acts, by means of which the worker screws the locking element 30 into the prepared receiving opening 22.21, in particular the blind hole of the second structure region 22.2, by means of the screw thread 32.
In the exemplary embodiment, the detent element 30 and the housing structure 22 are made of plastic, so that the connection between the detent element 30 and the housing structure 22 is a plastic-plastic connection. In this case, it is provided that, in order to establish the assembled state between the locking element 30 and the housing structure 22, a worker acts on the outer polygonal structure 33.1 from the outside by means of a corresponding tool, in particular a nut wrench or a screw socket, in order to establish the connection.
The problem that arises is that the installation space of the outer polygonal structure 33.1, which extends laterally in the +/-y direction, must be made free as an assembly space in order to be able to produce the desired assembly state. This assembly space inside the housing structure 22 is thereby disadvantageously not available for further components of the lighting element 20.
In addition, the already mentioned first structure region 22.1, which forms the corresponding connection point V to the cover glass 21 close to the holder region, can be designed on the outer polygonal structure 33.1 side, viewed in the-y direction, next to the assembly space.
In addition, the prior art solution has the disadvantage that, due to the use of the external screw thread 32 as a fastening element, the detent element 30 needs to have a relatively long blind hole 22.21 with a length value X2 in the longitudinal direction (see longitudinal axis X) in order to produce a corresponding stability between the second component region 22.2 and the detent element 30, the length value X2 being located between the second component region 22.2, in particular the end face of the blind hole 22.21, and the bottom of the blind hole 22.21. Furthermore, the connecting rod, which is designed as a transition element 33 and comprises the external polygonal structure 33.1 necessary for assembly, has a relatively large length also in the longitudinal direction (see longitudinal axis X), the length value X1 being formed between the holder region and the end face of the second structure region 22.2, in particular the end face of the blind hole 22.21.
In other words, in the conventional solution, the transition region Bx1 of the latching element 30, which is located outside the housing structure 22 (between the holder region and the second structure region 22.2) and has the length value x1, and the fastening region Bx2, which is located inside the housing 22 (between the end face and the bottom of the blind hole 22.21), are relatively long (x1+ x2), so that a relatively large installation space volume is required, viewed in the +/-x direction, in order to establish the desired connection between the lighting element 20 and the holder 10 by means of the conventional connection of the components 10, 20, 30, 40.
Fig. 1 also shows that, as a result of the arrangement described, a structural space B, indicated in fig. 1 by a dashed oval, is not available inside the lighting element 20, since it is occupied by the first and second structural regions 22.1, 22.2 of the housing structure 22.
It is, however, desirable that, in particular, the fourth structure region 22.4, i.e. the cover or the design cover, can be guided further in the-x direction and/or in the + y direction with respect to the illustration in fig. 1, wherein the position of the opening 11 in the holder region should remain unchanged.
Therefore, a solution is sought in accordance with the proposed technical problem in order to form such a structural space B, which is referred to below as "new" structural space BN(see fig. 2 and subsequent figures).
In a first principle step, the invention consists in modifying the second structural region 22.2 of the housing 22 in such a way that the space requirement for the position of the transition region Bx1 and/or the fastening region Bx2 is reduced, so that the second structural region 22 is retracted further in the direction-x.
In a second principal step, the invention consists in modifying the second structural region 22.2 of the housing 22 in such a way that a movement of the second structural region 22.2 of the housing 22 in the + y direction is also achieved by adapting the space requirement of the position of the transition region Bx1 and/or the fastening region Bx 2.
The invention discloses further embodiments which follow the principle of the inventive concept and which are explained below.
The first embodiment:
fig. 2 in accordance with the first embodiment likewise shows a section a-a in the same x/y plane as fig. 1.
According to a first step according to the invention, the component 20, which is detachably fastened to the holder 10, is equipped with a detent element 30, which is a detent segment 31 on one side, with a ball arranged on the end face of the detent element 10; 30.2, in a manner similar to fig. 1, are detachably engaged in the holder 10 and the end of the base part 34 of the latching element opposite the latching section 31, which is designed in a stepped manner in the exemplary embodiment of the first embodiment, is inserted into an injection mold and is encapsulated, so that the base part 34 is injection-molded in a form-fitting manner into the stepped receiving opening, in particular the stepped blind hole opening 22.22, of the second structure region 22.2 of the housing 22.
In this way, during a preparatory phase of the assembly of the lighting element 20, the base part 34 is mounted by injection molding (in-mold molding), during which the housing structure 22 is formed at the same time, so that a housing and the latching element 30 are provided, which are integrated in the housing structure 22, in particular in the second structural region 22.2, in a form-fitting and material-bonded manner; 30.2 (for attaching to a holder on the vehicle body side).
Fig. 2 shows that no separate tool is required for the pre-production, as a result of which a transition region Bx12 with a length value of x12 is formed, which transition region Bx12 is shorter than the transition region Bx1 with a length value of x1 in the prior art (Bx12 < Bx 1).
Furthermore, the locking element 30 is fixed in the second structural region 22.2 by means of injection molding; 30.2, a stable composite structure can be created between the base part 34 and the blind opening 22.22, which requires a smaller structural depth than the solution shown in fig. 1, whereby a fixing zone Bx22 with a length value x22 is also formed, said fixing zone Bx22 being shorter than the fixing zone Bx2 with a length value x2 of the prior art (Bx22 < Bx 2).
The result is that the space requirement of the transition region Bx12 and the fastening region Bx22 is thereby reduced, so that the second structural region 22.2 of the housing 22 is moved overall in the x direction, thereby forming a new structural space B in the x directionN。
In addition, unlike the prior art according to fig. 1, no assembly space has to be made available for the tool, viewed laterally in the-y direction, since this solution does not require any tools. In a second step, the first structure regions 22.1 can thus be formed in such a way that, starting from the connection points V, the webs 22.11 can be designed essentially in the y direction, which webs are formed longer in the + y direction than in the prior art. This longer web 22.11 thus extends into the region which was occupied in the prior art by the provision of assembly space, whereby (see fig. 1) the structure of the second structure region 22.2 on its side facing the cover glass 21 (to the left of the longitudinal axis X) is substantially no longer required, so that the desired new structure space B is created for the design of the covering 22.4N。
The design screen 22.4 is shown in fig. 2 by cross-hatched lines in relation to possible extensions of the prior art, wherein it is clear that only the webs 22.11 form the boundary of the extension of the design screen 22.4 in the x direction, viewed in the x direction.
The first step according to the invention thus provides the premise that the desired structural space B is formed by stepwise lengthening of the structural component in the-x direction and in the + y directionN。
The second embodiment:
fig. 3 according to the second embodiment likewise shows the section a-a in the same x/y plane, as in the previous figures.
According to a first step according to the invention, the component 20, which is detachably fastened to the holder 10, is equipped with a detent element 30, which is a detent segment 31 on one side, with a ball arranged on the end face of the detent element 10; in a manner similar to fig. 1, the locking element 30.3 is detachably engaged in the holder 10 and has an end opposite the locking section 31, which in the second embodiment is designed as a fastening element 32 with a screw head drive 35 arranged on the end side, in particular a screw external thread of a mitre-slot drive (Torx-antitrieb), so that the screw external thread 32 as a fastening element can be screwed in a form-fitting manner (as a plastic-plastic connection) in the receiving opening, in particular in the through opening 22.23, of the second structure region 22.2 of the housing structure 22 from the inside into the second structure region 22.2 by means of the drive 35. Between the driver 35 and the second structural region 22.2 of the housing structure 22, preferably on the housing side, a pressing rib is arranged for sealing the interior of the lighting element 20.
Here, the assembly is not carried out in a preparation phase for the assembly of the lighting element 20, but rather can be carried out before the assembly of the lighting element 20 at the holder 10, wherein, during the assembly of the latching elements 30; 30.3 and the housing structure 22 before the mounting of the cover glass 21.
As is clear from fig. 3, since the fastening means no longer require a separate tool acting from the outside of the lighting element 20, a transition region Bx13 with a length value x13 is formed, which transition region Bx13 is shorter than the transition region Bx1 of the prior art with a length value x1 (Bx13 < Bx 1).
In the present exemplary embodiment, the fastening region Bx23 with the length value x23 is not significantly shorter than the value x2 of the conventional fastening region Bx2 according to fig. 1, since the plastic-plastic thread connection 32 as a fastening connection requires a certain length x2, x23 in the fastening regions Bx2, Bx 23.
In contrast to the prior art according to fig. 1, however, no mounting space for the tool acting from the outside, as viewed in the direction-y, has to be made available, since in this solution too no tool acting from the outside is required. In this way, the first structure region 22.1 can be designed in the second step in such a way that, starting from the connection point V, the web 22.11 can be designed essentially in the y direction, which is longer in the + y direction than in the prior art. This longer web 22.11 thus extends into the region which was occupied in the prior art by the installation space of the preparation tool, whereby (see fig. 1) the structure of the second structure region 22.2 on its side facing the cover glass 21 (to the left of the longitudinal axis X) is substantially no longer required, so that the desired new installation space B is created for the design screen 22.4N. The design screen 22.4 is again shown in fig. 3 by cross-hatched lines in relation to possible extensions of the prior art, wherein it is clear that only the webs 22.11 also form the boundary of the extension of the design screen 22.4 in the x direction, viewed in the x direction.
The first step according to the invention also provides in this second embodiment that the desired installation space B is formed by stepwise lengthening of the structural component in the-x direction and in the + y directionN。
The third embodiment:
fig. 4 according to a third embodiment likewise shows a section a-a in the same x/y plane, as in the previous figures.
According to a first step according to the invention, the component 20, which is detachably fastened to the holder 10, is equipped with a detent element 30, which is a detent segment 31 on one side, with a ball arranged on the end face of the detent element; 30.4 are detachably engaged in the holder 10 in a manner similar to fig. 1 and have, opposite the latching section 31, an end which is designed in the embodiment of the third embodiment as a cylindrical pin 37, so that the cylindrical pin 37, which is in turn designed as a base part, can be screwed into the second housing region 22.2 in a form-fitting manner in a receiving opening, in particular a blind hole 22.24, of the second housing region 22.2 of the housing structure 22 by means of a separate fastening part 36 from the inside, the fastening part 36 having a drive 36.1, in particular a slot drive.
The second structure region 22.2 and the cylindrical pin 37 provided as the fastening element 32 have openings into which the fastening part 36 can be screwed as a plastic-plastic screw connection, wherein the surface of the drive element 36.1 facing the second structure region 22.2 serves to seal the interior of the lighting element 20 from the surroundings of the lighting element 20.
Here again, the assembly is not carried out in a preparation phase for the assembly of the lighting element 20, but rather can be carried out at the holder 10 before the assembly of the lighting element 20, wherein, during the assembly of the latching elements 30; 30.4 and the housing structure 22 before the mounting of the cover glass 21.
As is clear from fig. 4, since the fastening means no longer require a separate tool acting from the outside of the lighting element 20, a transition region Bx14 with a length value x14 is formed, which transition region Bx14 is shorter than the transition region Bx1 of the prior art with a length value x1 (Bx14 < Bx 1).
In the present exemplary embodiment, the fastening region Bx24 with the length value x24 is not significantly shorter than the value x2 of the conventional fastening region Bx2 according to fig. 1, since the plastic-plastic thread connection 36, 36.1 (see fig. 4) by means of the fastening element 36 likewise requires a certain length x2, x24 in the fastening region Bx2, Bx 24.
In contrast to the prior art according to fig. 1, however, no mounting space for a tool acting from the outside, viewed in the-y direction, has to be left, since this solution also does not require such a tool acting from the outside. This again makes it possible to design the first structure region 22.1 in a second step according to the invention in such a way thatStarting from the connection point V, the web 22.11 can be designed essentially in the y direction, which is longer in the + y direction than in the prior art. This longer web 22.11 thus extends into the region which was occupied in the prior art by the installation space reserved for tools, whereby (see fig. 1) the structure of the second structure region 22.2 on its side facing the cover glass 21 (to the left of the longitudinal axis X) is substantially no longer required, so that a new desired structure space B is created for the design screen 22.4N. A possible extension of the design mask 22.4 relative to the prior art is again shown in fig. 4 by cross-hatching, wherein it is clear that only the webs 22.11 form the boundary of the extension of the design mask 22.4 in the x direction, viewed in the x direction.
The first step according to the invention is therefore also provided in this third embodiment that the desired structural space B is formed by stepwise lengthening of the structural component in the-x direction and in the + y directionN。
The latching element 30 preferably comprises a flange-like stop 33.2 (stop flange) in the region of the bridge-like (stepartig) transition element 33 embodied as a cylindrical pin, which stop serves for positioning the latching element 30 relative to the second structure region 22.2 when the fastening element 36 is screwed in. During assembly, pressure is exerted on the latching element 30 from the outside in the direction of the housing structure 22 in the direction of the arrow according to arrow P4, so that the support region of the flange-like stop 33.2 facing the second structure region 22.2 is supported in a positively positioned manner on the end face of the blind hole 22.24 of the second structure region 22.2. A corresponding exact and positive support of the fastening element 36 is ensured by the flange-like stop 33.2. It goes without saying that the bottom side of the locking element 30, and therefore of the cylindrical pin 37, can generally also serve as a stop for the position of the locking element 30 relative to the second design region 22.2, so that the flange-like stop 33.2 can also be omitted if necessary.
The following embodiment is based essentially on the basic concept according to the first embodiment, wherein, however, the method of assembling the locking element 30 is modified as described below.
The fourth embodiment:
fig. 5 according to the fourth embodiment likewise shows the section a-a in the same x/y plane, as in the previous figures.
According to a first step according to the invention, the component 20, which is detachably fastened to the holder 10, is equipped with a detent element 30, which is a detent segment 31 on one side, with a ball arranged on the end face of the detent element; 30.5 are detachably engaged in the holder 10 in a manner similar to fig. 1 and have an end opposite the detent section 31, which in the embodiment of the fourth embodiment is designed as a cylindrical pin 36, so that the cylindrical pin is fixed in a form-fitting manner and, as explained below, in a material-locking manner in a receiving opening, in particular a blind hole 22.25, of the second structure region 22.2 of the housing structure 22.
In the fourth embodiment, the assembly takes place in a preparatory phase to the assembly of the lighting element 20 by producing a friction-welded connection between the cylindrical pin (see fig. 5), which is again designed as a base part 37.1, and the housing structure 22, wherein the cylindrical pin 37.1 is integrated in the second structural region 22.2 of the housing structure 22, in particular in a form-fitting and material-engaging manner, so that the housing structure 22 of the lighting element 20 has the form-fitting and material-engaging integrated latching element 30; 30.5, the locking element is used for being additionally arranged on a holding piece on the vehicle body side.
The form fit is ensured by a corresponding contour between the cylindrical pin (outer contour) designed as the base part 37.1 and the cylindrical blind hole 22.25 (inner contour).
According to the invention, the material connection is achieved by producing a friction-welded connection.
In other words, the latching elements 30; 30.5 are designed as friction welding elements as follows.
A latch element 30; 30.5 are preferably constructed entirely of plastic and include at least one friction welding attachment element.
A latch element 30; the main body (Korpus) of 30.5 is alternatively made of metal and is designed as a friction-welded housing or as a friction-welded housing with friction-welded attachment elements arranged thereon, at least in the region of the receiving opening, in particular the blind hole 22.25, of the second design region 22.2 of the housing design 22.
Completely or partially enclosing the latching element 30; the friction-welded housing of the body of 30.5 or the friction-welded housing with the friction-welded attachment elements arranged therein is likewise made of plastic.
A latch element 30 having a friction weld attachment element; 30.5 or friction welded housing and friction welded element are made of rigid and stable plastic, such as thermoplastic with or without reinforcing fibers, such as polypropylene (PPF), Polyamide (PA) and PA 6.6GF 30; polycarbonates and polymer blends, for example PC/ABS, PC + ABS/PC, ABS + ABS/PC.
The housing structure 22 and the latching element 30, which is completely made of plastic; 30.5 the material of either the friction-welded housing or the friction-welded attachment element is expediently formed from a similarly stable or identical plastic material. It is also possible for the housing structure 22 to be produced from a thermosetting plastic, while the latching elements 30; 30.5 either the friction welded housing 30 or the friction welded attachment element is constructed from a thermoplastic material.
During the friction welding process, the friction welding attachment element or the friction welding housing and the friction welding attachment element preferably form a polymer closure (Polymerverkrallung) with the housing structure 22, so that a reliable material-bonded connection is achieved in addition to a form-fitting connection.
A latching element 30, which is designed as a friction welding element in one of the variant embodiments described above; 30.5 are moved by means of a drive device, not shown in detail, by relative displacement, preferably by rotation of the friction welding element about its longitudinal axis X and axial displacement of the rotating friction welding element, into the receiving bore 22.25 of the housing, so that the latching element 30, which is a friction welding element; 30.5 and the housing structure 22, in particular the second structural region 22.2 of the housing structure 22, form a material-bonded friction-welded connection.
The housing structure 22 and the latch element 30; 30.5, in addition to the rotation of the friction welding element, the relative movement can also be achieved by torsional vibrations, i.e. a reciprocating movement of the friction welding element in the receiving bore 22.25 of the housing structure 22 over a limited angle of rotation, or only by axial vibrations, i.e. along the latching element 30 in the receiving bore 22.25 of the housing 22; 30.5 of the longitudinal axis X.
In the case of torsional and/or axial vibrations, friction welding elements which are not rotationally symmetrical themselves and/or are arranged in receiving openings which are not rotationally symmetrical can also be fastened, precisely when very small amplitudes are used.
Another alternative consists in the combination of the above-mentioned relative movements or in the selection of said relative movements, so that there is a relative Orbital oscillation (Orbital-Schwingung). This measure is already specified in WO 2014/124841, but the locking element 30 according to the invention; 30.5 are designed in other ways and the way of use of the method differs from the known way of use as will also be explained by the following description.
The inventors have used only the known basic concept consisting in using a friction welding method in which the heat to melt the material is generated by friction in the surface areas lying against each other by means of the relative movement of the two components to be fixed to each other.
Fig. 5 shows that the production of the above-described prefabricated, i.e. friction-welded connection between the cylindrical pin, which is again designed as a base part 37.1 (see fig. 5), and the housing structure 22, in particular the second structural region 22.2 of the housing structure 22, eliminates the need for separate tools, and thus produces a transition region Bx15 with a length value x15, which transition region Bx15 is shorter than the transition region Bx1 of the prior art with a length value x1 (Bx15 < Bx 1).
Furthermore, the latching elements 30 are connected by friction welding; 30.5 in the second structure region 22.2, a stable composite structure can be formed between the stud pins 37.1 and the blind holes 22.25, which composite structure requires a smaller constructional depth than the solution shown in fig. 1, whereby a fixing region Bx25 with a length value x25 is also formed, which fixing region Bx25 is shorter than the fixing region Bx2 with a length value x2 in the prior art (Bx25 < Bx 2).
The result is that the space requirement for the transition region Bx1 and the fastening region Bx2 is thereby reduced, so that the second structural region 22.2 of the housing 22 is displaced in its entirety in the x direction, thereby forming a new structural space B in the x directionN。
In contrast to the prior art according to fig. 1, the tool does not have to be freed from fitting space when viewed laterally in the-y direction, since this solution does not require any tools. In a second step, the first structure regions 22.1 can thus be formed in such a way that, starting from the connection points V, the webs 22.11 can be designed essentially in the y direction, which webs are formed longer in the + y direction than in the prior art. This longer web 22.11 thus extends into the region which is occupied in the prior art by the provision of assembly space, whereby (see fig. 1) the structure of the second structure region 22.2 on its side facing the cover glass 21 (to the left of the longitudinal axis X) is substantially no longer required, so that a desired new structure space B is created for the design of the covering 22.4N. A possible extension of the design mask 22.4 relative to the prior art is shown in fig. 5 by cross-hatching, wherein it is clear that only the webs 22.11 also form a boundary, viewed in the x direction, for the extension of the design mask 22.4 in the x direction.
The first step according to the invention thus again provides that the desired structural space B is formed by stepwise lengthening of the structural component in the-x direction and in the + y directionN。
The friction-welded connection specifically designed in the fifth embodiment can be designed in different variants, wherein the first variant is shown in fig. 5.
A latch element 30; 30.5 is made entirely of plastic and comprises a friction-welded additional element in the form of a rib, which is arranged on the underside of a stop 33.2 (stop flange) in the form of a flange in the region of a transition element 33, which is designed in the form of a bridge as a cylindrical pin.
The bottom side of the cylindrical pin designed as a base 37.1 and thus the latching element 30; the bottom side of 30.5 constitutes a depth limit stop in the blind hole 22.25, determining the position of the cylindrical pin 37.1 within the housing structure 22.
In the friction welding, heat is generated by the relative movement at least between the friction welding attachment element and the housing structure 22 and thus the inner wall of the blind hole 22.25, wherein the latching element 30; the movement of 30.5 is preferably realized as an axial oscillation, i.e. along the latching element 30; the longitudinal axis X of 30.5 reciprocates axially in the receiving bore 22.25 of the housing 22 in the direction of directional arrow P5. Thus, at least at the latching elements 30; a positive and secure material-bonded connection is achieved between the stop flange 33.2 of 30.5 and the housing structure 22.2.
In a second variant embodiment of the fifth embodiment, which is not shown, the detent element 30; 30.5 are likewise composed entirely of plastic and comprise friction-welding additional elements, preferably in the form of ribs, which are arranged on the underside of the cylindrical pin designed as a base part 37.1.
The flange-like stop 33.2 (stop flange) arranged in the region of the bridge-like transition element 33 designed as a cylindrical pin then serves only as a positioning for the detent element 30.5, so that it has no friction-welded additional elements. In this variant embodiment, the housing structure 22 and the latching element 30; between 30.5, a locking element 30 is defined; as a relative movement, a reciprocating movement of 30.5 is effected in the receiving bore 22.25 of the housing 22 along the longitudinal axis X in the direction of the directional arrow P5 over a limited angle of rotation. A positive and reliable material-bonded connection is thus achieved at least between the base of the cylindrical pin designed as the base part 37.1 and the base of the blind hole 22.25 of the housing structure 22.
It goes without saying that the arrangement of the flange-like stop 33.2 is optional.
In a third variant embodiment, which is likewise not shown, only the bottom side of the cylindrical pin 37.1 of the base part 37.1 and thus the locking element 30; the underside of 30.5 is designed as a depth-limiting stop in blind hole 22.25, so that the position of cylindrical pin 37.1 in housing structure 22 is determined by the material melted by the friction-welded connection. The friction-welded additional element is then preferably also arranged in the form of a rib on the underside of the cylindrical bolt 37.1 and melts during the formation of the friction-welded connection, so that the latching element 30; 30.5 finally reach its desired position at least between the bottom of the cylindrical pin 37.1 and the bottom of the blind hole 22.25 of the housing structure 22 as a form-fitting and reliable material-bonded connection. In this third variant embodiment, the stop plane and the friction welding plane are identical on the bottom of the cylindrical pin 37.1 and on the bottom of the blind hole 22.25 of the housing structure 22.
Unlike the third modified embodiment, in the first and second modified embodiments, the stopper plane and the friction welding plane are separated from each other.
Fifth embodiment:
fig. 6 according to a fifth embodiment likewise shows the section a-a in the same x/y plane, as in the previous figures.
The above explanations for the fourth embodiment apply analogously to the fifth embodiment, wherein the same reference numerals are used for the same components.
The difference is that the form fit is ensured by the corresponding contour in the fifth embodiment (see fig. 6) between the cylindrical pin (outer contour), which is now conically designed as the base part 37.2, and the blind hole 22.26 (inner contour), which is now conically shaped. Differently designed latching elements 30 in the base part; 30.6 can thus be introduced into the blind hole 22.26 when forming a friction-welded connection, wherein in a preferred variant of this embodiment at least one friction-welded additional element is preferably arranged on the radial outer circumference of the cylindrical pin 37.2 relative to the longitudinal axis X, as shown in fig. 6.
In this variant embodiment, it is also proposed that the housing structure 22 and the latching element 30; 30.6, the latching elements 30; 30.6 reciprocate in the receiving bore 22.25 of the housing 22 along the longitudinal axis X in the direction of the directional arrow P6 over a limited angle of rotation. At least in the case of the conical circumferential surface of the pin, which is designed conically as the base part 37.2, and the conical blind hole 22.26 of the housing structure 22, the locking element 30 is thus oriented; 30.6, a form-fitting and reliable material-bonded conical circumferential welded connection is achieved. In this variant embodiment, the stop plane and the friction welding plane, which may be so-called v-shaped, are separated from each other.
Sixth embodiment:
fig. 7 according to a sixth embodiment likewise shows a section a-a in the same x/y plane, as in the previous figures.
Fig. 7 shows a further embodiment of a further solution, which essentially corresponds to fig. 5 (fourth embodiment) and the associated description, but with the following differences, namely the locking element 30; 30.7 has a flange-like stop 33.2 (stop flange) on the end face of the cylindrical pin 37.1 designed as a base part 37.1 opposite the ball 31, which serves to position the detent element 30 relative to the second component region 22.2; 30.7.
the transition element 33, which is designed as a bridge-shaped cylindrical pin, and the base part, which is designed as a cylindrical pin 37.1 in the fastening region Bx27, are thereby steplessly transitionally connected to one another in a cylindrical manner. Furthermore, through-holes 22.27 are formed in the housing structure 22 instead of the blind holes 22.25 (see fig. 5).
During assembly, the latching elements 30 are engaged in the direction of the housing structure 22 according to the directional arrow P7; 30.7, a pressure is exerted so that the bearing region of the flange-like stop 33.2 facing the second component region 22.2 rests in a position-matched manner on the underside of the housing component 22 against the passage opening 22.27 of the second component region 22.2 of the housing component 22.
A latch element 30; in this embodiment, 30.7 is made of, for example, plastic and includes a friction-welded attachment element in the form of a rib, which in this embodiment is now arranged on the upper side of the flange-like stop 33.2 (stop flange).
In the sixth embodiment, the locking element 30 is formed by a flange-like stop 33.2 arranged on the end face of the cylindrical pin 37.1; 30.7 limit the stop with respect to the depth of the housing structure 22. The position of the cylindrical bolt 37.1 in the housing structure 22 is also determined by the material melted by the friction welding connection, since at least one friction welding additional element in the form of a rib is now arranged on the upper side of the flange-like stop 33.2 (stop flange).
The friction-welded additional element, preferably in the form of a rib, of the cylindrical pin 37.1 melts during the formation of the friction-welded connection, so that the latching element 30; 30.7 finally reach the desired position at least on the underside of the housing structure 22 as a form-fitting and reliable material-bonded connection. In this sixth embodiment, the stop plane and the friction welding plane are identical on the bottom side of the housing structure 22 in a plane between the housing structure 22 and the upper side of the flange-like stop 33.2 (stop flange).
The seventh embodiment:
fig. 8 shows a section a-a in the same x/y plane as in the previous figures.
Fig. 8 shows a further embodiment of a solution which essentially corresponds to fig. 6 (fifth embodiment) and the associated description, but with the following differences, namely the locking element 30; 30.8, on the end face of the cylindrical pin 37.1 opposite the ball 31, a flange-like stop 33.2 (stop flange) is provided, which serves to position the locking element 30 relative to the second structural region 22.2 of the housing structure 22; 30.8.
the transition element 33, which is designed as a cylindrical pin, and the base part 37.2, which is designed as a conical pin in the fastening region Bx28, are thereby steplessly transitionally connected to one another, wherein the transition element 33 is cylindrically configured and the base part 37.2 is conically configured. Furthermore, instead of the conical blind hole 22.26, a conical through-hole 22.28 is formed in the housing structure 22 (see fig. 6).
During assembly, the latching elements 30 are engaged in the direction of the housing structure 22 according to the directional arrow P8; 30.8, a pressure is exerted so that the bearing region of the flange-like stop 33.2 facing the second component region 22.2 rests in a position-matched manner on the underside of the housing component 22 against the passage opening 22.28 of the second component region 22.2 of the housing component 22.
In this seventh embodiment, the form fit is ensured, similarly to the fifth embodiment, by a corresponding contour between the pin (outer contour) which is designed conically as the base part 37.2 and the now conical through-opening 22.28 (inner contour). Differently designed latching elements 30 in the base part 37.2; 30.8 can thus be introduced into the through-opening 22.28 with the formation of a friction-welded connection, wherein in a preferred variant of this embodiment, at least one friction-welded additional element is preferably arranged opposite the latching element 30; the longitudinal axis X of 30.8 is arranged on a radial circumferential surface as shown in fig. 8 in a manner similar to fig. 6.
In this variant embodiment, it is also proposed that the housing structure 22 and the latching element 30; 30.8, the latching elements 30; 30.8 reciprocate in the receiving bore 22.28 of the housing 22 along the longitudinal axis X in the direction of the directional arrow P8 over a limited angle of rotation. At least on the circumferential surface of the conical base part 37.2 and the through-opening 22.28 of the housing structure 22 facing the latching element 30; 30.8, a form-fitting and reliable material-bonded conical circumferential welded connection is achieved.
In this variant embodiment of the seventh embodiment, the stop plane and the friction welding plane, which can be said to be v-shaped, are separated from one another.
At the latch element 30; in the embodiments of fig. 5 to 8 according to fig. 5 to 8 in which the fastening regions Bx25, Bx26, Bx27, Bx28 are connected by friction welding, the respective transition regions Bx15, Bx16, Bx17, Bx18 are formed with a length x15, x16, x17, x18, which is shorter than the length x1 of the transition region Bx1 of the prior art (Bx15, Bx16, Bx17, Bx18 < Bx 1).
Furthermore, the latching elements 30 are connected by friction welding; 30.5, 30.6, 30.7, 30.8 are fixed in the second structural region 22.2 of the housing structure 22, a stable composite structure can be formed between the cylindrical or conical pins 37.1, 37.2 and the blind holes 22.25, 22.6 or the through-holes 22.27, 22.28, which requires a smaller construction depth than the solution shown in fig. 1, as a result of which also fixing regions Bx25, Bx26, Bx27, Bx28 are formed with length values x25, x26, x27, x28 which are shorter than the length value x2 of the fixing region Bx2 of the prior art (Bx25, Bx26, Bx27, Bx28 < Bx 2).
In this embodiment, too, the possibility of constructing the connecting plate 22.11 longer than the connecting plate 22.11 from the prior art arises, said connecting plate 22.11 thereby extending into the region which was occupied in the prior art by the installation space which was reserved for the tool. As a result (see fig. 1), the structure of the second structure region 22.2 on its side facing the cover glass 21 (to the left of the longitudinal axis X) is substantially no longer required, so that in all embodiments, a desired new installation space B is created for the design screen 22.4N. The design screen 22.4 is also shown in fig. 5, 6, 7 and 8 by cross-hatched lines in relation to possible extensions of the prior art, wherein it is clear that only the webs 22.11 form the boundary of the extension of the design screen 22.4 in the x direction, viewed in the x direction.
