[0002] Motor vehicle technical operating device

[0003] The invention relates to a motor vehicle actuating device, in particular a motor vehicle door handle sensor unit, with at least one printed circuit board for receiving electrical / electronic components, and with a housing for receiving the printed circuit board equipped with the components.

[0004] Such automotive actuating devices are used, for example, in conjunction with motor vehicle door handle sensor units or as such. For this purpose, the motor vehicle door handle or motor vehicle exterior door handle in question is equipped with one or more sensors inside. These can be proximity sensors, force sensors, or the like, as described, for example, in DE 10 2012 100 428 A1. This concerns a door handle for a motor vehicle that interacts with a locking mechanism of a motor vehicle door. Several electronic components are integrated into a housing and connected to on-board electronics. Some of the electronic components are encapsulated in a shell. The electronic components comprise a circuit board, an antenna, a first sensor, and a second sensor. The first sensor is activated when the motor vehicle is locked.

[0005] With the help of the sensor unit implemented, the invention can, for example, detect the approach of an operator seeking access to the relevant vehicle door. Capacitive sensors can be used for this purpose. In principle, contactless operation is also possible at this point, with wireless communication taking place between the vehicle door handle sensor unit and an operator-side element, such as a transponder. All of these approaches aim to at least unlock the vehicle door equipped with a vehicle lock and, if necessary, also open or prop it up. This has proven particularly advantageous for convenience reasons.

[0006] For example, DE 601 25 538 T2 discloses a sensor system for keyless access. This system uses an element to generate an incident beam using electromagnetic radiation. A detection element is also provided. This allows a user to be identified and access to the device to be guaranteed.

[0007] DE 101 34 958 A1 describes a printed circuit board for accommodating electronic components. A film hinge is arranged on at least one side edge of a printed circuit board element, via which the printed circuit board element is integrally connected to another printed circuit board element. Conductor tracks are attached to the film hinge.

[0008] The prior art, which forms the generic and represents the starting point, according to DE 10 2012 109 031 A1, concerns an electronic sensor unit for a motor vehicle. This unit is equipped with a housing and a control and evaluation device arranged in the housing. The control and evaluation device is, in turn, coupled to a control device of the motor vehicle. At least one capacitive sensor electrode is also provided. In this way, changes in the capacitive sensor electrode's capacitance can be detected by the control and evaluation device.

[0009] The housing, the control and evaluation device, and the at least one capacitive sensor electrode, in conjunction with a lighting device, form an integral assembly. For this purpose, the housing can be equipped with at least one joint area that divides the housing into several housing sections and movably connects them. At least one portion of the housing is coated with an adhesive to simplify attachment to a body component.

[0010] The state of the art has generally proven itself, but still offers room for improvement. While it is generally known to encapsulate printed circuit boards for accommodating electrical / electronic components with a potting compound, thus protecting them from environmental influences, moisture, dust, etc., this procedure requires an upstream manufacturing step before the thus potted circuit board, populated with components, can be placed in the housing. The housing then typically has to be attached to or in a body component. The body component is not limited to a motor vehicle door handle or a component thereof. This results in considerable costs because various coordinated assembly steps must be completed. The invention aims to remedy this situation.

[0011] The invention is based on the technical problem of further developing such a motor vehicle actuating device in such a way that the manufacturing and assembly costs are reduced compared to previous procedures.

[0012] To solve this technical problem, the invention proposes, starting from a motor vehicle actuating device of the structure described at the outset, that the housing, including the printed circuit board located therein, together with the components arranged thereon, has an encapsulation as a whole.

[0013] According to the invention, and in contrast to the generic prior art, in particular according to DE 10 2012 109 031 A1, the procedure is such that, for example, the circuit board populated with the electrical / electronic components is not coated with a potting compound. Rather, protection against any environmental influences, such as moisture, dust, or dirt, is achieved by encapsulating the housing as described. This hermetically seals the housing. As a result, the components located inside are also hermetically sealed and, in particular, protected against environmental influences such as moisture, dust, or dirt. These components located inside the housing are specifically the at least one circuit board located therein, together with the electrical / electronic components arranged thereon.

[0014] This means that the circuit board with its components is not directly encased in, for example, a potting compound, but rather the circuit board in question and the components are enclosed in a housing. This allows for assembly improvements and thus cost savings right from the start. This is because the housing, with the circuit board inside and populated with components, can be prefabricated and standardized. Furthermore, according to preferred embodiments, the housing can be used as a transport case for the circuit board including the components.

[0015] This means that the enclosure and the circuit board with the components mounted on it can be used for transport to the installation site. The enclosure acts as a transport case for the circuit board populated with the components. At the installation site, all that remains is to equip the entire transport case with the encapsulation that completely encloses the housing. Electrical contacting of the components may be necessary beforehand. The enclosure is now ready for immediate installation or mounting.

[0016] It should be emphasized that the automotive actuating device is expressly not limited to motor vehicle door handles. Rather, the automotive actuating device according to the invention can also be one that generally actuates electrical actuators, for example, a window lifter drive, an electric seat adjustment, or a lid lock such as a fuel tank lock or charging socket lock. Likewise, the described automotive actuating device can be used, for example, to open a motor vehicle hood or tailgate.In this context, it becomes clear that the term "motor vehicle door handle" and, consequently, "motor vehicle door" is not limited to, for example, pivoting motor vehicle side doors, but rather encompasses any motor vehicle flap on or in a motor vehicle for closing an opening. Furthermore, it is not just about the operation of flaps; the described motor vehicle actuation device can also be used to actuate other actuators, such as the aforementioned window lift drive, seat adjustment, mirror adjustment, etc.

[0017] In addition to the described simplified assembly and the associated cost savings, a further advantage is that the invention deliberately dispenses with, or can dispense with, the additional coating of the circuit board populated with components with a potting compound. This, in principle, avoids any problems associated with such an overmolding process from the outset. In fact, such an overmolding process is known to work with hot plastic compound. This fundamentally prevents any negative temperature influences on the electronic components and also those resulting from the flow rates associated with the injection molding process. This is because the encapsulation is carried out by the housing, and the populated circuit board located inside is generally not affected.

[0018] In principle, it is of course also possible, if necessary, to overmold the circuit board populated with components with a potting compound. The interior of the housing can also be filled with the potting compound if necessary. This provides additional protection, which is generally not necessary due to the complete encapsulation of the housing. A soft material is usually selected as the potting compound inside the housing to ensure the functionality of sensors arranged on the circuit board, such as strain gauges, metal-encapsulated sensors, etc.

[0019] The housing can be encapsulated in any conceivable way. For example, it is possible for the encapsulation to be in the form of a plastic film surrounding the housing, which is shrunk onto the housing. Generally, however, the encapsulation is implemented as an overmolding, for example, made of plastic. It has proven particularly advantageous if the housing is connected to at least one body component and, for example, reinforced or generally plugged into a connector. In this case, the body component can also be equipped with the encapsulation, at least in the connection area with the housing.

[0020] This means that in this case, the housing is first connected to at least one body component. This can be done, for example and without limitation, by rusting or clipping. The housing is then equipped with the encapsulation. In addition, the encapsulation covers at least the connection area between the housing and the body component. This allows a relatively "loose" coupling to be used in the connection area between the housing and the body component, which offers assembly and cost advantages. This "loose" coupling is acceptable in that not only is the housing subsequently completely overmolded or equipped with the encapsulation, but the connection area between the housing and the body component is also equipped with the relevant encapsulation.This is because the additional encapsulation reinforces and stiffens the connection area, making further connection measures unnecessary. In principle, it is even conceivable in this context for the housing to be connected to at least one body component by mutual contact without locking, provided the continuous encapsulation is subsequently applied and additionally ensures the mechanical coupling of the housing to the body component, at least in the connection area.

[0021] The housing itself can be constructed in several parts, for example, with a base and a cover. Depending on the desired shape at the installation location, it is conceivable to design the housing with an L-shaped cross-section. This allows the housing to be adapted to the typically L-shaped shape of the vehicle door handle or exterior vehicle door handle. Of course, this is only an example.

[0022] In the case of a multi-part housing with a base and lid, the base and lid are generally designed separately. Conventional joining techniques can be used to connect the base and lid. For example, the base and lid can be connected in a snap-in manner, thus enhancing the housing's additional functionality as a transport case. Such a snap-in connection can usually be opened again.

[0023] However, it is also possible for the base and cover to be formed as a single piece. In this case, the base and cover are connected to one another in an articulated manner, for example via a film hinge. The invention is based on the knowledge that the housing as a whole is made from a plastic, preferably a thermoplastic. In this case, an injection molding process is usually used to produce the housing. The articulated connection between the base and cover makes it easy to implement the previously mentioned L-shaped design in cross-section. In this case, there is even the further possibility of the circuit board populated with the components being constructed as a whole in several parts. The individual circuit board components can be coupled to one another in a similar way via a film hinge.

[0024] In this way, for example, one L-shaped leg of the L-shaped housing serves to accommodate a circuit board, while the other circuit board, connected via a film hinge, is housed in the second L-shaped leg of the housing. This simplifies assembly and attachment to the body component. Furthermore, the standardizations described above can be implemented particularly cost-effectively.

[0025] Of particular importance is the fact that the housing is equipped with at least one coupling area for coupling, for example, a sensor on the circuit board to the body component. This coupling area can have a very different design compared to the rest of the housing, depending on which sensor is to be coupled to the body component. The invention is based on the knowledge that the sensor located on the circuit board must not be impaired in terms of its desired functionality by the housing which accommodates the populated circuit board or by the encapsulation which completely encloses the housing. If, for example, the sensor is a strain gauge, it must therefore be ensured that the voltage measured using the sensor orIn this example, the strain or compression of the body component measured by the strain gauge can be perfectly transferred to the strain gauge located on the circuit board inside the housing by interposing the housing in conjunction with the encapsulation. For this purpose, the wall thickness of the housing can be modified in the area of ​​the strain or compression to be measured.

[0026] For this purpose, the wall thickness can be designed, for example, to be thicker or thinner than in other areas outside the coupling area. Furthermore, any behavior of the housing under load, such as deflection, can be specifically modified in the coupling area relative to the other areas of the housing. This can be achieved, for example, by deliberately inserting ribs and stiffeners that, for example, stiffen the housing outside the coupling area, but allow deformation inside the coupling area, which is then perfectly detected by the sensor or strain gauge in the example case.

[0027] Another option for designing the coupling area is simply to equip the housing with a window. In the simplest case, this allows a switch arranged as a sensor on the circuit board to be activated. In this context, it is understood that the window is not equipped with the encapsulation surrounding the housing. Instead, a potting compound is (additionally) used inside the housing, which is only left out in the area of ​​the switch.

[0028] In principle, other modifications to the housing in the coupling area are also conceivable. For example, the plastic used to manufacture the housing can be modified not only in terms of its thickness, but also by introducing other materials into the coupling area, such as a metal film that interacts or can interact with a capacitive sensor on the circuit board. Deformations of the coupling area can thus be used particularly effectively to apply pressure to the capacitive sensor.

[0029] Finally, the coupling area can be made completely or partially transparent. This can be achieved by making the plastic in the coupling area particularly thin or by using a transparent plastic in the coupling area. In this way, light signals can be transmitted from the body component to a sensor sensitive to the light signals on or at the circuit board. Of course, combinations of the previously described possibilities are also conceivable and are encompassed by the invention.

[0030] Furthermore, a further advantageous variant of the invention consists in the housing having at least one support area for external components attached therein or thereto, such as a light guide. In this case, the housing is used as a storage area for the external components in question. The external components are components that are not accommodated inside the housing on or at the circuit board. A light guide represents a typical external component for attachment to the housing. The invention is based on the finding that motor vehicle door handle sensor units in particular are generally equipped with a light source that can emit an optical signal.The light source can be a component of a lighting device to guide an operator to the motor vehicle door handle in question, particularly at night or in poor lighting conditions. Furthermore, the lighting device generally ensures that a target area is marked on a surface. This target area informs the user or operator in which area contactless operation of the motor vehicle door or hatch equipped with the motor vehicle door handle is actually possible.

[0031] In any case, according to the invention, the housing with its support area functions as a holder or bearing for such foreign components, for example the light guide, with the aid of which light emanating from a light source, for example an LED, is guided through the light guide in such a way that, in the example case, the desired illumination of the target area is achieved.

[0032] The result is an automotive actuation device that is both cost-effective and easy to assemble. Furthermore, any functional impairments of the electrical / electronic components arranged on the circuit board are inherently avoided. This is achieved by equipping the housing, which houses the populated circuit board, with a completely encapsulated enclosure. The enclosure can also be used to stiffen a connection area between the housing and a body component. This represents the key advantages.

[0033] The invention is explained in more detail below with reference to a drawing which merely represents an exemplary embodiment; in the drawings:

[0034] Fig. 1 A to 1 F the manufacture of the housing with the printed circuit board inserted therein, which is equipped with electrical / electronic components and

[0035] Fig. 2A to 2C the attachment of the housing produced in this way to a body component of the motor vehicle equipped therewith.

[0036] The figures depict a motor vehicle actuating device. In the example, and not by way of limitation, the motor vehicle actuating device is a motor vehicle door handle sensor unit. This means that the exemplary embodiment involves a sensor unit S, which is shown in its completed state in Fig. 1F and is attached to a motor vehicle door handle, and in particular to a motor vehicle exterior door handle T, which is schematically illustrated in Fig. 2C. In principle, other locations and possible uses are also conceivable, as explained in the introduction to the description.

[0037] In any case, the motor vehicle actuating device or the motor vehicle door handle sensor unit and thus the sensor unit S, as shown in Fig. 1F, initially has a printed circuit board 1, 2, 3 which serves to accommodate electrical / electronic components 4, 5. According to the illustrations and not by way of limitation, the electrical components 4, 5 are a control unit 4 which, via an indicated plug strip with connected conductor cables, is in electrical contact with a further, motor vehicle-side central control unit, which is not shown. The further component 5, according to the exemplary embodiment, is designed as a sensor 5 and in particular a force sensor, with the aid of which an actuating force F exerted by an operator on the outside door handle T can be detected.

[0038] The actuating force F, as shown in Fig. 2C, ensures that the outside door handle or motor vehicle outside door handle T undergoes a certain deformation, which can be detected using sensor 5. For this purpose, sensor 5 according to the exemplary embodiment is, and is not limited to, a strain gauge sensor. Signals from the strain gauge sensor or sensor 5 are recorded and evaluated by control unit 4 and transmitted to the motor vehicle control unit (not shown). As a result, the recorded force signals are interpreted as an operating request from a user wishing to gain access and, for example, after additional user identification, a motor vehicle door equipped with the motor vehicle door handle or motor vehicle outside door handle T is unlocked and, if necessary, subsequently opened.

[0039] In addition to the already mentioned circuit board 1, 2, 3 for accommodating the electrical / electronic components 4, 5, the basic structure of the sensor unit S includes a housing 6, 7. According to the exemplary embodiment, the housing 6, 7 is designed in several parts with a base 6 and a cover 7. It can also be seen that the housing 6, 7 is L-shaped in cross section and in the side view according to Fig. 1A. The same applies to the circuit board 1, 2, 3 accommodated inside the housing 6, 7. In fact, the circuit board 1, 2, 3 is composed of a first circuit board section 1 and a second circuit board section 2, which are coupled to one another via a film hinge 3. According to the exemplary embodiment and according to the sequence in Figures 1 D and 1 E, the first circuit board section 1 of the circuit board 1, 2, 3 is received in a predominantly horizontal L-leg of the base 6 of the housing 6, 7.In contrast, the second circuit board section 2 is accommodated in the largely vertical L-shaped leg of the base 6. After the circuit board 1, 2, 3 has been placed in the base 6, the base 6 can be closed using the cover 7, as can be seen in the transition from Fig. 1 E to Fig. 1 F. The closure between the base 6 and the cover 7 can be supported by an additionally provided snap-in connection 8, which is indicated in the figures.

[0040] Before and before the circuit board 1, 2, 3 is inserted, a foreign component 9 has been introduced into the housing 6, 7. According to the exemplary embodiment, this is a light guide 9 which, in conjunction with an additionally provided and not shown LED or generally a light source, serves, in the installed state, according to the illustration in Fig. 2C, to optically mark the target area described in the introduction to the description on a background. This target area may belong to a handle recess (not shown) of the motor vehicle door (likewise not shown), which is equipped with the motor vehicle door handle or motor vehicle exterior door handle T. With the help of the target area, an operator or user is informed about how the motor vehicle door handle orMotor vehicle exterior door handle T and where it is best applied, for example in order to be able to apply the actuating force F indicated in Figure 2C with precision in order to document an opening request on the part of the user.

[0041] For this purpose, the external component or light guide 9 is introduced into a support area 10 of the housing 6, 7 or fixed to this support area 10. In the exemplary embodiment, the support area 10 of the housing 6, 7 is a web projecting downwards from the vertical L-leg of the base 6, to which the external component or light guide 9 is or can be connected. For this purpose, the light guide 9, according to the exemplary embodiment, is guided in a receiving trough which is inserted into the relevant web or the support area 10 of the housing 6, 7 and, for example, snapped into place. Other designs of the support area 10 on the housing 6, 7 are of course also possible.

[0042] After the housing 6, 7 in the sequence of figures 1A to 1C has first been equipped with the foreign component or light guide 9 and the printed circuit board 1, 2, 3 equipped with the components 4, 5 has been mounted inside the housing 6, 7, the housing 6, 7 is closed. This is done via the latching or latching connection 8. Not shown is the further possibility of previously, i.e. before the housing 6, 7 is closed, the printed circuit board 1, 2, 3 equipped with the components 4, 5 is equipped with a potting compound sealing the printed circuit board 1, 2, 3. Such an additional seal is conceivable, but is not implemented in the exemplary embodiment.

[0043] According to the invention, the housing 6, 7, including the circuit board 1, 2, 3 located therein, together with the components 4, 5 arranged thereon, comprises an encapsulation 11 as a whole. This encapsulation 11 can be seen in particular in Fig. 2C.

[0044] First, however, the sensor unit S manufactured in Fig. 1F is connected to at least one body component 12 in the further step according to Fig. 2A. In the exemplary embodiment, the body component 12 is, and not limited to, a metal carrier 12 which, for example, can be attached to or is present on the motor vehicle door (not shown) or a door leaf belonging thereto. Of course, the metal carrier 12 can also be a component of the door leaf in question. In either case, the metal carrier 12 serves not only to accommodate and hold the sensor unit S, but also the motor vehicle door handle or motor vehicle exterior door handle T equipped with the sensor unit S, as can be seen from Fig. 2C, which shows the final production state.

[0045] The housing 6, 7 is now first connected to the body component 12 at the transition from Fig. 2A to Fig. 2B, according to the exemplary embodiment, either reinforced with it or forming a plug connection with the body component 12. This defines a connection area 13 between the body component 12 and the housing 6, 7.

[0046] Finally, the housing 6, 7, including the connection area 13 with the body component 12, is equipped with the previously mentioned encapsulation 11. In the exemplary embodiment, the encapsulation 11 is, and is not limited to, an overmolding made of plastic. It is understood that the plastic used as an optional potting compound for the circuit board 1, 2, 3 or the interior of the housing 6, 7, as well as the plastic used to create the encapsulation 11, is each electrically insulating. Furthermore, the plastic is designed to prevent any damage to the electrical / electronic components 4, 5. In any case, the continuous attachment of the encapsulation 11 orThe overmolding with the plastic ensures that, on the one hand, the housing 6, 7 is hermetically sealed, and, on the other hand, the connection area 13 between the housing 6, 7 and the body component 12 is additionally stiffened by the potting compound 11. As a result, the connection area 13 of the housing 6, 7 with the body component 12 can also be designed as a plug-in connection and be relatively "weak" because the necessary connection is ultimately established via the encapsulation 11.

[0047] The cover 7 is generally attached to the base 6 of the housing 6, 7 using a film hinge. This is because the housing 6, 7 is made of a thermoplastic. This provides the additional option of standardizing the housing 6, 7. This means that regardless of the intended use and installation location, the housing 6, 7 can be designed the same. This also applies to the printed circuit board 1, 2, 3. This results in a further advantage in that the housing functions and can function as a transport case for the printed circuit board 1, 2, 3 including the components 4, 5. This means that the printed circuit board 1, 2, 3 can be populated with the components 4, 5 and then placed inside the housing 6, 7. This can be realized and implemented spatially and functionally separately from the attachment of the housing 6, 7 to the body component 12.This is because the housing 6, 7 is also intended and designed as a transport housing for the circuit board 1, 2, 3 equipped with the components 4, 5.

[0048] As already explained above, the sensor 5 according to the exemplary embodiment is a strain gauge sensor, with the aid of which the actuating force F exerted on the motor vehicle door handle or motor vehicle exterior door handle T in Figure 2C can be detected. To ensure that a smooth force transmission can take place at this point from the motor vehicle door handle T via the interposed housing 6, 7 to the sensor 5 in question, and to ensure that the sensor 5 or the strain gauge actually measures and can measure the deformation, the housing 6, 7 is equipped with at least one coupling region 14. This coupling region 14 is located in the illustrated example at the base 6 of the housing 6, 7. Furthermore, the coupling region 14 is arranged in the immediate vicinity of the sensor 5 and its size is adapted to the extent of the sensor 5.

[0049] In order that in this context the actuating force F on the motor vehicle door handle T can ultimately be transmitted via the coupling region 14 in the base 6 of the housing 6, 7 to the sensor 5 attached to the circuit board 1, 2, 3 or the second circuit board section 2, the coupling region 14 is, for example, equipped with a reduced wall thickness compared to the other regions of the housing 6, 7 or the base 6. This reduced wall thickness in the coupling region 14 ensures that the deformations induced by the actuating force F in the motor vehicle door handle T are also transmitted to the directly adjacent housing 6, 7 or the base 6 and specifically to the coupling region 14. As a result, the coupling region 14 is also deformed and its deformations can be recorded using the sensor 5 or the strain gauge, which is, for example, directly adjacent to the coupling region 14.The signal emitted by the strain gauge is interpreted by control unit 4 as corresponding to an opening request from the operator. This opening request is transmitted from control unit 4 to the vehicle-side control unit, where it is interpreted as meaning that the motor vehicle (not shown) is opened.

[0050] The lock of the corresponding vehicle door is unlocked. In principle, a subsequent opening movement of the door leaf of the vehicle door in question is also conceivable.
