Description

The invention relates to an actuation unit of a movable part of a motor vehicle, in particular a tailgate, with an actuation part which is attached to a housing part, at least two conductor elements which are arranged on the housing part, an elastically deformable contact element which interacts with the conductor elements and one on the actuation part arranged plunger for deforming the contact element.

From the DE 10 2005 034 763 B3 discloses an operating unit with a movable operating part which is attached to a non-movable housing part. When the actuating part is activated manually, a contact element arranged within the actuating unit, the Is part of an electric switch, contacted or deformed, whereby the conductor elements are short-circuited via the contact of the deformed contact element with the conductor elements. In this way, for example, a signal can be generated which leaves the actuation unit in order, for example, to activate an electric drive which is provided, for example, on a closing device of the tailgate. In order to protect the electrical components from moisture and thus from corrosion, they are usually enclosed with a potting compound. The moisture enters the interior space, for example, via a ventilation hole provided in the actuation unit. These ventilation bores are usually arranged on the housing part and connect the outer area of the actuating unit with the interior of the actuating unit, which is delimited by the actuating part and the housing part, in order to allow a volume displaced by the actuating part to escape.

DE 10 2006 024 292 A1 discloses the preamble of claim 1.

It is the object of the present invention to create an actuation unit for a movable part of the vehicle which is designed in such a way that a significantly faster and more cost-effective production with good functional properties can be achieved.

To solve this problem, an actuating unit with the features of claim 1 is proposed. Preferred developments are set out in the dependent claims.

For this purpose, it is provided according to the invention that the actuating part and the housing part delimit an interior space that is completely encapsulated from the environment, and the actuating part is pivotably mounted about an axis that is axially symmetrical to the interior space. The essence of the invention is the construction of the electrical components to simplify within the actuation unit. During manual actuation, the actuating part moves axially symmetrically to the interior of the actuating unit, so that pressure equalization of the interior is not necessary. Since the actuating part is mounted so that it can pivot about the axis symmetrically to the interior space, air does not have to be displaced from the interior of the actuating unit in any position of the actuating part. For this reason, the arrangement is more complex Ventilation holes not necessary. Thus, the actuating part and the housing part can be completely encapsulated, in particular shielded, from the environment, so that, for example, dirt or moisture cannot penetrate into the interior. The electronics in the interior of the actuation unit are thus protected, which means that the service life of the device according to the invention and its functional properties can be increased significantly. Consequently, in the present invention, it is possible to dispense with encasing the conductor elements and / or the elastically deformable contact element in a complex and water-tight manner with potting compound, resin or the like, since the actuation unit according to the invention, in particular its interior, is completely encapsulated from the environment.

According to the invention, a holding element is fastened to the housing part in such a way that at the same time the contact element is reliably held in its position. Thus, the contact element can be reliably held in its position on the housing part via a retaining element that is structurally less complex.

The conductor elements advantageously run through the wall of the housing part and are connected to an electrical connector. This can be a sealing plug, as a result of which the interior is completely closed off from the exterior. Furthermore, it is conceivable that the conductor elements are provided with a potting material or adhesive at least in some areas, in particular where the conductor elements leave the interior of the actuating unit. Reliable encapsulation of the interior is also possible as a result.

In one possible embodiment of the invention, the actuating part and the housing part are materially connected to one another at their peripheral edge regions. It is conceivable here for the edge regions of the actuating part and the housing part to be laser-welded to one another. Other material connections, such as the adhesive connection, are also conceivable.

The axis about which the actuating part can be pivoted axially symmetrically to the interior space expediently runs inside the interior space. For this purpose, for example, corresponding bearings can be provided in the interior of the actuation unit, on which the actuation part moves when activated manually and thus triggers a corresponding signal via the activation of the contact element. The construction of the actuation unit can also be designed in such a way that the pivot axis about which the actuation part rotates axially symmetrically to the interior space extends outside the interior space. For this purpose, corresponding bearing points can be provided, which ensure an axially symmetrical movement to the interior during the activation of the actuating part.

According to the invention, the housing part comprises a contoured body to which the holding element or the contact element is attached. The contoured body can extend out of the housing part in the direction of the actuating part, for example as a kind of pedestal. In order to facilitate the assembly of the contact element, the holding element or the contact element is attached to the contoured body in a form-fitting and / or force-fitting manner. For example, a latching or clip connection can be provided here that reliably holds the contact element between the holding element and the conductor elements. It is advantageously provided that the contoured body is designed with at least one fixing element to which the holding element or the contact element is attached.

The housing part is advantageously designed with channels that are open on one side and in each of which a conductor element extends. The open channels are guideways in order to reliably insert the conductor element into the housing part during assembly. Here, the channels advantageously run parallel to one another. The open channels extend in the direction of a sleeve element formed on the housing part into which the conductor elements open. The sleeve element has the function of an electrical plug that can be connected to electrical components provided outside the actuation unit.

The conductor elements can be designed at least in some areas with a surface which is designed like a toothing and which acts on the housing part, whereby a reliable fixation of the conductor element within the interior of the actuating unit can be achieved. The conductor element can have one or more toothings that penetrate the material of the housing part at least on its surface during assembly and thus ensure reliable fixation of the conductor element within the open channel. This prevents the conductor element from being inadvertently released from the channel due to any vibrations on the actuating unit during the overall assembly of the actuating unit.

The conductor element expediently has at least one projection-like stop means that prevents the conductor element from being unintentionally pulled out of the interior. It is conceivable here that the conductor element can be unintentionally pulled out of the actuation unit via a corresponding tensile force at the free end of the conductor element within the sleeve element. The stop means, which is arranged, for example, transversely to the extension of the rod-shaped conductor element, offer sufficient resistance to the material of the housing part.

According to the invention, the holding element has an opening so that the contact element can be contacted by the plunger. The contact element can be, for example, a curved hard metal plate, snap disk. As a result of a predetermined compressive force of the plunger exerted on the concavely curved surface, the contact element bulges and strikes the contact surfaces of the conductor elements with its previously convexly curved surface. The electrical contact between the conductor elements is thus established. A restoring force advantageously acts on the actuating part, which always tries to move the actuating part back into its starting position in which there is no electrical contact between the conductor elements. For example, the restoring force can originate, among other things or solely, from the contact element, which strives to suddenly return to its arched starting position when the actuating force on the actuating part decreases. It is also conceivable that the restoring force is generated via a spring element which supports the restoring process of the actuating part. Around To protect the contact element from force overload, the actuation unit can have limiting means which restrict a deflection movement of the actuation part.

In a preferred embodiment of the invention, the actuating part is designed as a multi-component injection-molded part made of plastic. Here, the actuation part can consist of a hard component and a soft component, the edge area of the actuation part, which is fastened to the housing part, and the plunger consisting of the soft component. The central area of the actuating part, on the other hand, consists of a hard component on which latching means are provided which are connected to one another with corresponding counter-latching means on the housing part. Here, a first latching means can be designed like a shell and the second latching means, which is designed as a corresponding counter-latching means, can be held by the first latching means. The second latching means advantageously has a bearing body which is positively held on the first latching means, the second latching means being rotatably mounted on the first latching means so that the actuating part can be pivoted reliably when activated by the user. In this case, the pivot axis of the actuating part advantageously runs through the first and the second latching means. The first latching means can, for example, be arranged on the housing part and the second latching means, on the other hand, can be arranged on the actuating part. In order to ensure reliable mounting of the actuating part on the housing part, the latching means of the actuating part and of the housing part consist of the hard component.

The design of the plunger with the soft component creates a feel that is appealing to the user when the actuating part is activated. Furthermore, the soft component has the effect that, even with a somewhat greater force on the actuating part, a corresponding stroke compensation can be achieved via a deformation of the plunger, whereby the risk of damage to the contact element can be reduced. The mechanical resistance of the soft component is advantageously between 30 Shore A and 70 Shore A.

The fastening section is advantageously designed in the area of the opening with a wing element which engages the fixing element, in particular is oriented obliquely to the fixing element, whereby a reliable fastening of the contact element on the housing part is ensured.

The Figure 1 and Figure 2 show an actuation unit of a movable part 1 of a motor vehicle, which in the present case is a tailgate 1. The tailgate 1 is in Figures 1 and 2 shown purely schematically. The actuation unit has an actuation part 10 which is fastened to a housing part 20 in the assembled state of the actuation unit. On the housing part 20, two conductor elements 21 are arranged, on which an elastically deformable contact element 22 made of metal is located. The contact element 22 is in Figure 2 only indicated in dot-dash lines. A plunger 11 is provided on the actuating part 10 which, when the actuating part 10 is manually actuated, depresses the contact element 22, as a result of which an electrical connection between the conductor elements 21 made of metal is achieved. This enables a signal to be triggered, as a result of which, for example, a drive, not shown, of a closing device of the tailgate 1 can be activated so that the user can open the tailgate 1 of the motor vehicle.

In the present exemplary embodiment, the actuating part 10 and the housing part 20 are materially connected to one another at their peripheral edge regions 10a, 20a, that is to say, laser-welded in the present exemplary embodiment. As a result, the interior 2, which is delimited by the actuating part 10 and the housing part 20, completely encapsulated from the environment 3. This prevents any environmental influences from interfering with the functionality of the electronics provided within the interior 2. In the present exemplary embodiment, the actuating part 10 is designed as a type of rocker which is mounted pivotably about an axis 4. In the present exemplary embodiment, the axis 4 runs axially symmetrically to the interior space 2, which means that the volume of the interior space 2 is almost constant regardless of the pivot position of the actuating part 10. As in Figure 1 is indicated, the axis 4 runs inside the interior 2. It is also conceivable that the axis 4 extends outside the interior 2 in a further embodiment variant, not shown.

The rotary mounting of the actuating part 10 on the housing part 20 takes place via latching means 16, 26 that correspond to one another and are located in the interior space 2 and are connected to one another. The first latching means 26 of the housing part 20 is designed like a shell, in which the second latching means 16 of the actuating part 10 is rotatably received. The second latching means 16 is designed as a type of bearing body which is positively held on the first latching means 26, with the second latching means 16 being rotatably mounted on the first latching means 26 when the actuating unit is installed, so that the actuating part 10 is reliably pivoted about the axis 4 can.

The housing part 20 according to Figure 2 is formed with a contoured body 24 on which the conductor elements 21 and the contact element 22 are arranged at least in some areas. For reliable fastening of the contact element 22, a holding element 23 is provided, which according to FIG Figure 6 is attached to the contoured body 24. The contoured body 24 here has cylinder-like fixing elements 27 to which the holding element 23 is attached. The holding element 23 is designed with an opening 29, so that the contact element 22 can be reliably contacted by the plunger 11. As especially in Figure 6 and Figure 8 As is illustrated, the holding element 23 has two fastening areas 33, each with an opening 35 through which the cylinder-like fixing element 27 of the housing part 20 protrudes. Furthermore, the fastening area 33 is designed in the area of the opening 35 with a wing element 34 which engages the fixing element 27. The wing element 34 is here aligned obliquely to the fixing element 27, which effectively prevents the holding element 23 from becoming detached from the contoured body 24 or from the housing part 20 by any forces that may arise from the contact element 22.

As in Figure 2 as in Figure 4 to Figure 6 As can be seen, the housing part 20 has channels 25 which are open on one side and in each of which a conductor element 21 is located. When assembling the actuating unit, the conductor elements 21 are first inserted into the open channels 25 and the conductor elements 21 extend in the direction of a sleeve element 31 of the housing part 20, which is also shown in FIG Figure 7 is shown. Here, the free ends 21a of the conductor elements 21 end according to FIG Figure 3 in the sleeve element 31, which serves as a plug. The actuation unit can be electrically connected to other electrical components on the motor vehicle via the plug. So that the conductor element 21 cannot be unintentionally pulled out of the interior 2 from the actuation unit by a tensile force on the sleeve element 31, the conductor element 21 is provided with a projection-like stop means 28 according to FIG Figure 3 executed. This stop means 28 is wedge-shaped in the present exemplary embodiment and, with its end face, which is directed towards the free end 21a of the conductor element 21, forms an effective stop face which is attached to the housing part material according to FIG Figure 4 is applied. As in Figure 3 is explicitly shown, the conductor element 21 is at least partially formed with a toothing 30, which according to FIG Figure 4 acts on the housing part material in such a way that a reliable fixation of the conductor element 21 within the interior space 2 can be achieved. The teeth 30 are directed in the direction of the contact element 22, so that the conductor element 21 cannot fall out in the opposite direction to the sleeve element 31 during the assembly of the actuating unit.

After the conductor elements 21 have been inserted into the channels 25, which serve as guide tracks, in a first assembly step, the contact element 22 is placed on the contoured body 24 and on the conductor elements 21, which is shown in FIG Figure 5 is explicitly shown. The contact element 22 here has four bearing points 22a. The two left bearing points 22a according to FIG Figure 5 contact the left conductor element 21 here. The right bearing points 22a rest on the contoured body 24 of the housing part 20. The Right conductor element 21 runs below the contact element 22 and does not touch the contact element 22 when the actuating part 10 is not actuated. Only when via the plunger 11 according to FIG Figure 1 the contact element 22 is deformed in the direction of the conductor elements 21, a contact is made between the contact element 22 and the right conductor element 21, so that an electrical connection is established between the adjacent conductor elements 21.

So that the contact element 22 can be reliably placed on the housing part 20 during assembly, the housing part 20, in particular the contoured body 24, has holding areas 32 at various points which are both in Figure 4 as well as in Figure 5 are shown. These holding areas 32 are adapted in some areas to the contour of the contact element 22 and, among other things, also serve as a stop element for better adjustment of the contact element 22 on the housing part 20. How Figure 4 clearly shows, the channels 25 run up to the contoured body 24.

The inner workings of the actuation unit are preferably mounted using a mechanical assembly device, which means that both the conductor elements 21, the contact element 22 and the holding element 23 are automatically mounted on the actuation unit. As in Figure 4 is indicated, the channels 25 are also designed with a groove-shaped clearance 36 for the assembly device. The actuation part 10 is a two-component injection-molded part made of plastic. Here, the actuation part 10 is off Figure 1 and Figure 2 executed with a hard component, which is shown in gray. The edge region 10a and a connecting web 10b of the actuating arrow 10 according to FIG Figure 1 are made from a soft component, the plunger 11 also being made from said soft component. The locking means 16, however, are made from the hard component. The areas of the conductor elements 21 which are located below the contact element 22 are refined in the present exemplary embodiment, in particular have a gold coating. This prevents corrosion from occurring in these areas of the conductor elements 21.

In Figure 9 and Figure 10 is a further variant of the in the Figures 1 to 8 actuating unit shown. In contrast to the exemplary embodiments according to Figure 1 to Figure 8 , in which a holding element 23 is provided for reliably fixing the contact element 22, the contact element 22 is shown in FIG Figure 9 and Figure 10 designed in such a way that a holding element 23 can be dispensed with. Here, the contact element 22 is shown with a fastening section 43 according to FIG Figure 9 executed, which is formed with an opening 49 through which the fixing element 27 of the contoured body 24 or of the housing part 20 according to the exemplary embodiments Figure 1 to Figure 8 protrudes.

The fastening section 43 in the area of the opening 45 is designed with two wing elements 44 which each engage the fixing element 27. The wing elements 44 are aligned obliquely to the fixing element 27, whereby a reliable fastening of the contact element 22 on the housing part 20 is ensured. When the operating part 10 is activated by the user, the plunger 11 acts according to Figure 1 in the direction of the contact element 22 according to Figure 9 , which is deformed in the direction of the conductor elements 21, so that an electrical connection between the adjacent conductor elements 21 is established. As in Figure 9 as shown, the conductor members 21 are as in FIG Figure 3 executed with a toothing 30, a stop means 28 and a free end 21a. The assembly of the conductor elements 21 takes place as in the exemplary embodiments according to Figure 1 to Figure 8 which are already described above.

Figure 10 has a further variant of the contact element 22, which as in Figure 9 is attached directly to the housing part 20 without a holding element. The contact element 22 is according to Figure 10 configured with two fastening sections 43, each fastening section 43 according to the fastening section 43 of the exemplary embodiment Figure 9 corresponds to. This means that the fastening portion 43 from Figure 10 is fastened via its wing elements 44 to the fixing element 27 of the housing part 20 on both of its sides. Between the two fastening sections 43 is the surface section on which the plunger 11 from the Figure 1 works. If the actuating part is actuated by the user, the plunger 11 is deformed Figure 1 the contact element 22 so strong that an electrical connection between the adjacent conductor elements 21 is established. In the present exemplary embodiment, the conductor elements 21 are cylindrical, that is, they are circular in cross section. The free End 21a of each conductor element 21 is rectangular in the present embodiment. Of course, the conductor elements 21 according to Figure 10 by the conductor elements according to Figure 3 or. Figure 9 be exchanged and vice versa.

The contact element 22 according to Figure 9 furthermore has two support elements 46 which rest on the contoured body 24 of the housing part 20. The advantage of the embodiment according to Figure 9 and Figure 10 is that the contact element 22 is made of the same material, in one piece with its fastening section 43, whereby a reliable fastening of the contact element above the conductor elements 21 can be achieved in a simple constructive manner.
