Description

The present invention relates to a door handle according to the closer defined in the preamble of the independent device claim type. Furthermore, the invention relates to a door handle system according to the preamble of the independent system claim and a method according to the preamble of the independent method claim.

It is known in the art that such door handles are used in vehicles to provide mechanical manipulations for operating a door or hatch, as well as communication functions and / or switching functions.

The publication EP 2 607 581 A2 discloses z. B. a vehicle door handle having an electronics unit, thus the comfort of the vehicle in the access to increase. It is known that the electrical and electronic components are provided within the door handle with a potting compound to protect them from external weather conditions, such as moisture and mechanical influences. A disadvantage of this known solution that the potting compound has a high viscosity, so that they can run in all the cracks and gaps of the electronic unit to envelop or seal them without air pockets. Due to the high viscosity of the potting compound, this unfortunately tends to drag along cables or protruding objects or to creep along other parts, which on the one hand complicates the production and on the other hand, a large part of the potting compound can be lost.

It is therefore an object of the present invention to at least partially overcome the disadvantages described above. In particular, it is an object of the present invention to provide a solid and easy to manufacture door handle. In particular, the door handle should be ready to be automated without any problems.

The above object is achieved by a door handle having the features of the independent apparatus claim, a door handle system having the features of the independent system claim and by a method having the features of the independent method claim. Further features and details of the invention will become apparent from the respective dependent claims, the description and the drawings. In this case, features and details that are described in connection with the door handle according to the invention apply, of course, also in connection with the door handle system according to the invention and the method according to the invention, and in each case vice versa, so that with respect to the disclosure of individual aspects of the invention is always reciprocal reference or can be.

The object is achieved in particular by a door handle for a vehicle having a base part, which has a recess with at least one side wall, wherein an electronic unit can be arranged in the recess, and wherein the electronic unit has a printed circuit board, which can be equipped with electronic components, and wherein a contacting of the circuit board is carried out by at least one line, and is connectable by this line with the vehicle-side electrical system. In this case, it is provided in particular that the conduit protrudes from the recess in a transition region, and in particular projects beyond at least one side wall of the recess.

An essence of the invention is that the conduit in the transition area is not passed through a side wall of the recess of the base part, so that this opening, which is necessary for it, must be sealed. Especially this seal is a special problem, because the potting compound, because of its high viscosity, quickly overcome this seal. Especially in this case runs more or less then a large part of the potting compound out of the recess of the base part, which ultimately leads to the previously made door handle is completely unusable and must ultimately be disposed of. In order to precisely prevent this problem reliably, it is provided that the line projects beyond at least one side wall of this recess in a transition region. In order for the potting compound would eventually run up the line, which is known to be difficult to achieve in order to leak from the recess can. Due to the

Optionally, it may be provided that the line forms a bridge in the transition region from the recess, in order to project beyond at least one side wall. Due to the existing bridge, it is possible that the line protrudes from the recess and projects beyond a side wall. Subsequently, the line can be guided below the uppermost edge of the side wall, without the potting compound can flow along this line. This ensures that the potting compound, which is filled into the recess, remains therein and does not run along the (riser) line.

Furthermore, it can be provided within the scope of the invention that the electronic unit arranged in the recess is at least partially covered with potting compound, which can preferably be filled into the recess. Here, the line may protrude in the transition region of the potting compound, and preferably have a cutting angle between the line and a surface of the potting compound of greater than 25 °, preferably 35 °, more preferably 60 °, ideally greater 80 °. By the selected intersection angle between the line and the surface of the potting compound, which forms a plane substantially, it can be ensured that the potting compound with its high adhesive force, not the line runs up. Particularly recommended is when the line is perpendicular from the Surface of the potting compound, ie with a cutting angle α of about 90 °, is led out. In this case, it is particularly ensured that the potting compound remains in the recess. Subsequently, an angle or bend can follow in the line (after leaving the potting mass or the transition area) in order to guide the pipe horizontally over the side wall of the recess (see for orientation) Fig. 3b ). At this horizontal leg may adjoin another angle to lead down the line again. Overall, a quasi V- or U-shaped inverted bridge is formed, with the up and down legs of the bridge ideally running almost parallel to the side wall of the recess. This configuration of the lines with the bridge can be dispensed with further sealing measures of the lead-out lines from the recess in the filled potting compound.

It is also conceivable within the scope of the invention for the recess in the base part to have a longitudinal extension, wherein the recess in the base part has an upwardly directed opening in particular for a horizontal alignment of the longitudinal extent (see for orientation) Fig. 3a, 3b ). It is conceivable that the surface of the potting compound is aligned substantially parallel to the longitudinal extent. It is also conceivable that the potting compound at least partially or completely closes the existing opening. Conveniently, only the line (as part of the electronics unit) projects out of the potting compound and the remainder is arranged in the potting compound. This ensures optimum protection for the electronics unit and its contact points.

For example. it can be provided that a support element is present, which supports the line in the transition region. In order to improve the stability of the line, especially in the region of the bridge, the additional support element may be provided. This carrier element can also serve simultaneously for the electrical insulation of the individual conductors. In addition, it is conceivable that the support element supports at least the electronic unit partially or completely (mechanically). The carrier element may have a 1K or more K-injection molded part, wherein in particular the plug and a first part and a second part of the carrier element may consist of different plastics. The carrier element can also not only partially but also completely support the line between the printed circuit board and a plug part. It is also according to the invention possible that the carrier element supports the electronic unit, in particular the printed circuit board. Thus, the said support member can receive several functions at the same time, so that it forms a multi-functional component.

It should also be mentioned at this point that the support element does not necessarily have to include the plug part. Thus, it is also conceivable that the plug part is a separate component to the carrier element, which is e.g. connects to the support element to accommodate one end of the line can. This plug part can thus be flanged or fastened in a separate step on the line with the carrier element. However, it is also conceivable that also the carrier element (as an injection molded part) comprises the plug part, so that the carrier element forms a monolithic, cohesive and possibly material-integral component with the plug part.

Furthermore, it is optionally possible in the context of the invention that the line has at least one electrical conductor as a current path, preferably at least two conductors. Conveniently, the individual conductors of the line are electrically isolated from each other, so as to form different current and / or data paths. Advantageously, the line has at least two ends, wherein at least the ends of the line are galvanically finished. This refinement serves to improve the contact and / or the corrosion protection and can be carried out by a coating comprising at least chromium, tin, zinc, copper, silver, gold. Just gold is particularly beneficial as it does not corrode. Silver, however, is less expensive than gold and easier to coat. Since copper and tin are quite inexpensive compared to silver, the whole line can be coated with it. Ideally, the line may be formed three-dimensionally, in particular partially to a bridge. Thus, even the basic shape of the line allows the bridging of a side wall of the recess of the base part, as already described.

Another advantage can be achieved within the scope of the invention, when the line is designed as a stamped grid of a metal sheet with at least one conductor. This stamped grid can be produced in a punching step and can be deformed simultaneously or in a further step to the desired shape. For a simple and inexpensive production is possible. Furthermore, by the thickness of the metal sheet also directly the mechanical stability are influenced, so that possibly less plastic can be saved for a possible carrier element. Also, with sufficient mechanical stability of the stamped grid, the carrier element can be used only for isolation purposes. In an extreme case, an insulating varnish is sufficient to achieve insulation between the conductors of the line.

Furthermore, provision can be made for at least one conductor of the line to have an electrically conductive wire, with optionally a wire of a conductor being configured multi-core. Also, the thickness (cross-section) of the wire, the mechanical stability can be influenced. Such wires are already inexpensive to obtain even with insulation in a variety of configurations. In this case, the carrier element can also be used only in sections to support the line, which is conceivable even with a stamped grid. However, if less stable (or rigid) wires or wires are used with flexible conductors, it is advisable to provide the support member completely between the ends of the conduit for support.

A further advantage may be provided that the line is at least partially encapsulated in plastic and this injection molded part forms the support element. Thus, this support element fulfills at least two functions simultaneously. It is also conceivable that the carrier element is present at least between the ends of the line, completely, partially or in sections. As a result, plastic can be saved, which is heavier than the line itself recyclable. It is likewise possible for the carrier element to have holding elements which serve to support and / or receive the electronic unit, in particular the printed circuit board, in the recess of the base part. Thus, such a carrier element fulfills at least 3 functions simultaneously.

In the production of the carrier element in an injection molding process, the positional relationships between connectors and contacts for the circuit board are held by encapsulating the electrical conductors (plastic) on the one hand, the lines against each other and isolated from the environment and realized reproducible positional relationships between the contacts and the circuit board.

Both a plastic for the support element and the potting compound may advantageously have a dielectric strength of greater than 8 KV / mm for electrical insulation purposes. Ideally, this also creepage currents between the conductors can be safely avoided.

It is also advantageous if at least one end of the line, a plug part is present to allow a contact with a mating connector - in particular for the vehicle-mounted electrical system - without further connection points. Also, in this case, the end of the line protrude into the plug part or the ends can be shot into the plug part, whereby further connection points are reliably avoided. In order to obtain a reliable plug coupling even with vibrations in the vehicle, the plug part can have at least one latching means in order to be able to engage positively in particular with a mating connector on the vehicle side. Additionally or optionally, it is conceivable that the plug part has a sealing means in order to be able to be coupled, in particular with moisture protection, to a mating connector on the vehicle side. It is also conceivable that the base part forms at least partially or completely the plug part or at least partially surrounds or receives the plug part. Conveniently, in this case, the ends of the line are injected into the plug such part. Ideally, the plug part is arranged on a bearing end of the door handle, in particular of the base part. As a result, the assembly of the door handle on the vehicle can be facilitated with a handle support.

It may optionally be possible that an optical display element (with at least one light source) is present, wherein preferably the display element (also) is electrically connected to the line. By this display element, for example, an apron lighting can be realized. Also, the user of the vehicle, for example, by a green signal, the free entrance to the vehicle are displayed, whereas, for example, a red signal indicating the locking state. To facilitate the manufacture of the door handle in principle, the display element structurally separate to the electronics unit, in particular the circuit board, be configured. It is thus also possible to position the display element freely on the door handle - independently of the electronic unit. Thus, the display element can be arranged on the base part itself outside the recess or on the cover element.

It is also conceivable according to the invention that the display element has at least one LED or OLED as the light source, which emits visible light in preferably different, controllable colors. The possible uses of the door handle, as described above, can be significantly increased. It is also expedient if in particular the display element may have an at least partially translucent housing. Thus, it is not necessary for the base part or the cover part to have a light-permeable area for the display element. This also simplifies the production of the two components.

Advantageously, it may be possible in the invention that at least one conductor of the line as an electrical contact, in particular as a conductive spring contact and / or latching contact, protrudes from the carrier element to electrically contact a cover part for the base part. In this case, this electrical contact may preferably be welded, soldered, pressed and / or crimped to the conductor of the line. It is also conceivable that the electrical contact is made more stable by flanging or doubling the conductor.

It is also conceivable that a conductor of the lines from the circuit board is not guided to the plug part, but is coupled in a section between the plug part and circuit board with the electrical contact, in particular as a conductive spring contact and / or snap-in contact. This electrical contact may be guided on an upper side of the carrier element to the outside and there may contact an inner side of the cover part when it is placed for closing the door handle. Thus, the inside of the cover part, which may in particular have a chrome plating or metal facing, with the circuit board in a simple manner electrically coupled through the line.

According to an advantageous development of the invention it can be provided that the electronic unit has at least one proximity sensor, in particular a capacitive sensor, an antenna, a Hall sensor, an acceleration sensor, a temperature sensor or a control unit, wherein preferably the electronic unit has at least two proximity sensors, in particular capacitive sensors having a proximity sensor for a door handle inside and a proximity sensor for a door handle outside. By using the aforementioned sensors, the ease of use of the entire vehicle and the locking system can be significantly increased. Thus, for example, a timely approach of a user to the vehicle or the corresponding door handle can be detected metrologically by the proximity sensors to start an authentication process with an (external) ID tanner, which serves in particular as a key for the locking system. By another proximity sensor can be differentiated metrologically between an approach of a door handle outside and a door handle inside. Preferably, the proximity sensors are designed as capacitive sensors, which are particularly robust and maintenance-free. By using a Hall sensor, the position of the door handle to a door handle carrier can be reliably determined. Ideally, the Hall sensor is arranged at a working end of the door handle, as this passes through the largest adjustment when actuated.

In the context of the invention, it can preferably be provided that at least one proximity sensor is designed as a capacitive sensor with an electrode surface, wherein in particular the electrode surface is formed by the printed circuit board. Thus, this proximity sensor can be made particularly simple and inexpensive.

It is also advantageous if the electronics unit is equipped with SMD components, in particular on both sides. As a result, a particularly (geometrically) compact and automatically manufactured electronic unit can be produced. This electronic unit can also be used for small door handles or door handles with a small recess.

Likewise subject of the invention is a door handle system with a door handle according to one of the preceding claims. In this case, it is provided that a handle support is provided, which can be arranged on an inner side of a movable part, such as. A door or a flap, from the vehicle, to attach the door handle operable on the vehicle. Thus, the door handle system according to the invention brings the same advantages as have been disclosed in detail with respect to the door handle according to the invention described above.

In addition, the door handle system may be suitable to open a door, flap or Moto hood (as a moving part) particularly easy. In this case, a simple pulling movement on the door handle to open the movable part are sufficient. Ideally, the door handle is thus designed as a pull handle, in particular vehicle pull handle.

The invention also relates to a vehicle, in particular a motor vehicle, with at least one door handle according to the invention and / or door handle system.

2. b) Vergießen der Ausnehmung mit der eingelegten Elektronikeinheit durch Vergussmasse
3. c) Befestigen eines Deckelteiles auf dem Basisteil. Damit bringt das erfindungsgemäße

The invention likewise relates to a method for producing a door handle, in particular according to one of the corresponding claims, for a vehicle having a base part, which has a recess with at least one side wall, wherein an electronic unit can be arranged in the recess, wherein the electronic unit has a printed circuit board , which can be equipped with electronic components, and wherein a contacting of the circuit board is carried out by at least one line, and is connectable by this line with the vehicle-side electrical system. It is provided that at least the following steps are performed:

1. a) inserting the electronics unit in the recess of the base part
2. b) potting the recess with the inserted electronic unit by potting compound
3. c) attaching a cover part on the base part. This brings the invention

Expediently, the steps a) to c) take place in chronological order with or without overlaps. It is also provided in the context of the invention that the individual steps are carried out automatically in order to realize short production times and low costs. In addition, the method involves the same advantages as described in detail with respect to the door handle and / or the door handle system.

A further advantage within the scope of the invention can be achieved if the following step is provided after step a):
a1) gripping an optical display element and bending the associated conductor until the display element reaches its defined position outside the recess of the base part.

This step can also preferably be carried out automatically. The step a1) expediently takes place after step a) and before step b).

It has been found to be particularly advantageous if the associated conductor of the display element in the recess of the base part below the surface of the potting compound contacts the electronic part and / or bent, since then this contact point is also securely housed protected.

Procedure of the method according to the invention.

In the following figures, the identical reference numerals are used for the same technical features of different embodiments.

In the Figures 1 and 2 the door handle 10 according to the invention is shown in a three-dimensional view with a base part 11 and cover part 12. In this case, this door handle 10 has a longitudinal extent L (in FIG. 4 is shown) and has a working end 10.1 and a bearing end 10.2, which project through a (door) plate on a door or flap movable part 101 of the vehicle 100 to mechanically together with a handle support 91 of the door handle system 90 according to the invention Act. The door handle support 90 ensures a recording and attachment of the door handle 10 of the invention (s. FIG. 13 . in which the handle support 91 is shown in dashed lines, since it is located on the inside of the door 101).

Since the door handle 10 according to the invention not only assumes the functions on the vehicle 100 purely mechanically, but also enables keyless vehicle access, an electronic unit 14 is provided in the interior of the door handle 10, in particular in the base part 11. This electronic unit 14 is contactable via at least one plug part 25 with the vehicle-side electrical system 102 17th

In the FIGS. 3a and 4 the cover part 12 has been removed from the door handle 10 so as to release a view into the interior. Here is in the FIG. 3a Good to see that the base part 11 has a recess 13, in which the electronic unit 14 is at least partially or completely usable. The recess 13 in the base part 11 has side walls 13.1, so as to form a (down) closed container for the later to be filled Vergussmasse 23. Like in the FIG. 3a can be clearly seen, the potting compound 23 has a flat surface 23.1, wherein in a transition region 21, a line 18 for contacting 17 for electrical connection of the electronics unit 14 with the vehicle-side electrical system 102 protrudes from the potting compound 23 and forms a bridge 22 in this area , By this bridge 22 prevents a side wall 13.1 of the recess 13 is interrupted in the base part 11 in order to lead out the line 18 at this point. Thus, can be dispensed with a seal this point.

In the FIG. 3b is the transition region 21 shown schematically, in which the line 18 emerges from the surface 23.1 of the potting compound 23 and a side wall 13.1 of the recess 13 in the base part 11 projects beyond. It is also good to see the intersection angle α between the surface 23.1 and the potting compound 23 and the line 18. This is in the present case preferably 90 °.

In the FIG. 4 is the comparable door handle 10 off FIG. 3a However, without potting compound 23 shown. It can be clearly seen that in the recess 13, the electronic unit 14 is used, which is later filled with potting compound 23. The electronic unit 14 is fixed via a carrier element 24 in the recess 13 and is connected via the line 18th electrically connected in particular with the vehicle-side electrical system 102. The electronic unit 14 is inserted through the opening 13.2 of the recess 13 in the cover 12.

In the FIG. 6 the line 18 with the individual conductors 18.1 and the shaped bridge 22 is shown. In this case, the individual conductors 18.1 have been produced from a stamped grid 19 and reshaped. In addition, the line 18 has a contact 27, which may be configured as a conductive spring contact and / or latching contact, in particular to be able to contact a cover part 12 in an electrically conductive manner. Since the cover part 12 can also have a chromium layer or a chrome element, the contacting 17 between the electronics unit 14 and the cover part 12 can thus be produced in a particularly simple manner.

In the FIG. 7 the line 18 was out FIG. 6 wrapped with a support member 24 to give the three-dimensional shape of the conduit 18, in particular the molded bridge 22, more stability. In this case, the carrier element 24 was sprayed around the line 18 and the individual conductors 18.1 and forms an injection molded part made of plastic, whereby the individual conductors 18.1 are simultaneously electrically insulated. In addition, holding means 24.1 may be provided on the carrier element 24 in order to be able to at least partially receive and secure the electronic unit 14.

In the FIGS. 7 and 8 the plug part 25 is also arranged at one end 18.2 of the line 18, which can be produced simultaneously with the carrier element 24 as an injection-molded part (1K injection-molded part). It is also conceivable that this plug part 25 is connected separately to the carrier element 24 with the line 18. At another end 18.3 of the conduit 18 (the two ends 18.2, 18.3 are in FIG. 6 good to see) can take place a contact 17 with a circuit board 15 of the electronic unit 14. For this purpose, the individual conductors 18.1 at the end 18.3 through (conductive) holes in the circuit board 15 protrude to be soldered. Also, the ends 18.3 can be contacted with surface solder pads on the printed circuit board 15 17 and soldered so that they do not have to protrude through the circuit board 15 itself.

It is also conceivable that the carrier element 24 is formed in two or more parts, wherein a first part 24.2 between the circuit board 15 and the plug part 25 is provided, and a second part 24.3 supports more or less the circuit board 15 and in the recess 13th fixed in the base part 11. It is also conceivable that the carrier element 24 is configured in one piece, and thus supports not only the lines 18, but also the electronic unit 14 at the same time.

In the Figures 9-11 only the line 18, the support member 24 and the electronics unit 14 without the door handle 10 is shown in order to better represent these components.

In the FIG. 9 the assembly of plug part 25, line 18 and support member 24 and electronic unit 14 is shown, which is used as such in the recess 13 in the base part 11. This assembly is pre-assembled and is inserted from above (machine) through the opening 13.2 in the recess 13 in the base part 11. Subsequently, if a display element 26 is provided, this can be inserted over a bend of the associated conductor 18.1 up to a defined position outside the recess 13 of the base part 11. Thereafter, this assembly can be filled by the mentioned potting compound 23 within the recess 13. Since the recess 13 forms a self-contained container with the peripheral side walls 13.1, no potting compound 23 can leak in this manufacturing step. This ensures that the (process) step can also be automated, and in any case the electronics unit 14 is enveloped in the recess 13 with sufficient potting compound 23.

In the FIG. 10 is the assembly off FIG. 9 without the corresponding electronics unit 14 shown. It can be clearly seen that in the first part 24.2 of the support member 24 and the lines 18 are arranged, which protrude with their ends 18.3 for contacting 17 of the electronic unit 14 and the circuit board 15 from the support member 24. At least on the second part 24.3 of the support member 24 holding means 24.1 are provided, which serve for receiving and fixing the electronic unit 14 and at the same time make a fixation in the recess 13 of the base part 11. In the FIG. 10 is also good to recognize the bridge 22 in the first part 24.2 of the support member 24.

In the FIG. 11 is then a quasi-exploded view of the unit FIGS. 9 and 10 shown. Here, the line 20 with the individual conductors 18.1, in the form of a wire 20, is shown.

The electronic unit 14 has the printed circuit board 15, which is provided with a kink at least at one point, preferably provided with two kinks in order to be able to ideally adapt it to the recess 13 of the base part 11. Furthermore, the printed circuit board 15 in the present case is equipped on both sides with so-called SMD components, whereby a simple production and space-saving design is possible. The contact 17 for the end 18.3 of the line 18 is in the FIG. 11 clearly visible. In addition, at least one Hall sensor 28.2 (shown in dashed lines, since it is located on the other side of the printed circuit board 15) provided at the end of the circuit board 15, whereby the position of the door handle 10 in relation to the handle support 91 is technically detectable. In addition, the electronic unit 14 has a proximity sensor 28, preferably two or three, which are provided as capacitive electrode surfaces 28.1. For this purpose, corresponding electrode surfaces 28.1 may be formed on the printed circuit board 15, as in FIG FIG. 11 shown.

In the FIG. 12 is a side view of the support member 24 with its first and second part 24.2, 24.3, shown.
