Description

[0001] Actuating device for a moving part of a vehicle

[0002] The invention relates to an actuating device for a movable part of a vehicle.

[0003] Actuating devices in the form of door handles or wing-shaped handles on a handleless door for access devices in vehicles are generally known. Known actuating devices often have sensor devices or the electronic unit within the door handle, which are used to automatically operate moving parts, for example a door or a tailgate, in vehicles. Known sensor devices usually have sensors that can monitor and record the vehicle's surroundings in order to recognize a user. In order to arrange the sensor devices or the electronic unit, an interior space of a certain size is required in the actuating device. However, outward-projecting actuating devices with an unfavorable internal electronic unit disadvantageously lead to a deterioration in aerodynamics and air resistance, as well as to wind noise due to the disruptive geometry.i Starting from the prior art, the object of the invention is to overcome the disadvantages of the prior art and to provide a slim actuating device.

[0004] The invention is based on the features of the independent claims. Advantageous developments and refinements are the subject of the dependent claims.

[0005] The object is achieved by an actuating device for a movable part of a vehicle, which comprises a housing, a sensor for detecting an actuating action of a user, in particular in the form of an approach and / or a touch, an evaluation electronics, and an electrically conductive sensor carrier, which is arranged separately from the evaluation electronics.

[0006] The actuating device designed in this way enables a compact construction. Due to the efficient spatial distribution for the evaluation electronics and the sensor carrier, the actuating device can be reduced to the absolutely necessary size with regard to design freedom. The shape of the housing can itself represent a design feature. Preferably, the housing is designed in a shell construction from two or more shells. The invention provides an actuating device for a vehicle, preferably for an access system of the vehicle, for (preferably automatic) actuation (at least comprising

[0007] Locking and / or opening) of a, in particular handleless, movable part of the vehicle. The movable part is preferably in the form of a door, e.g. a side door, a sliding door, or a flap, e.g. a tailgate, fuel tank or loading flap, or a hood, of the vehicle. Usually, several movable parts are provided on the vehicle, in particular in order to be able to lock the interior of the vehicle.

[0008] The electrically conductive sensor carrier serves to position the sensor. The sensor can be designed as a separate component that is arranged on the sensor carrier. Alternatively, the sensor can be formed as a single piece in the sensor carrier. The actuating device according to the invention has the advantage that the housing of the actuating device can be designed to be as compact and flat as possible in the region of the sensor carrier, while the evaluation electronics are located in a safe and spacious location in the interior, where possible damage to the sensitive evaluation electronics due to the actuating forces is avoided.

[0009] Preferably, a bending-resistant insert is provided in the housing. The insert can be made of metal or plastic. The insert can be solid or designed with at least one recess as a ladder or grid structure. The recess is suitable for at least partially accommodating the sensor carrier or the sensor, thereby further optimizing the interior space. Thanks to the insert, sufficient rigidity is ensured and high actuating forces from the inside and outside can be absorbed in a more load-appropriate manner. This ensures a robust actuating device that is as free from false triggering as possible.

[0010] In an expedient embodiment, the housing has at least two sections, wherein a change in the spatial extent in the vehicle Y direction is provided between the sections. This has the advantage that the design freedom for arranging various components in the housing is increased. The interior of the housing can be designed such that a section of the housing which extends spatially in the vehicle Y direction is larger than the rest in the vehicle Z direction and / or in the vehicle X direction. Preferably, the housing has a section, wherein the section is located in the lower region in the vehicle X direction and / or on one side in the vehicle X direction and whose spatial extent in the vehicle Y direction is larger than the rest.

[0011] According to the above-mentioned embodiment, it is conceivable that the sensor carrier is arranged in the section with a reduced spatial extent in the vehicle's Y-direction. This makes the actuating section of the actuating device slimmer and more aerodynamic.

[0012] According to the above-mentioned design, it is also conceivable for the evaluation electronics to be arranged in the section with increased spatial extension in the vehicle's Y-direction. This design of the actuating device ensures that the protective function for the important and pressure-sensitive evaluation electronics is perfectly maintained by the housing.

[0013] It is also conceivable that the change in the spatial extension on the housing is designed as a guide for the user's finger. This guides the user's finger to the correct actuation point on the actuation device, where the sensor is located, thereby further enhancing operator ergonomics.

[0014] In one embodiment of the invention, the sensor carrier can be a printed circuit board. This can be a single-layer or multi-layer circuit board. The use of a printed circuit board offers the advantage of enabling a finer structure for the sensor.

[0015] As a second option, the sensor carrier could be a cable. The sensor could, for example, be formed directly from the wound cable.

[0016] In a particular embodiment of the invention, the sensor carrier is a stamped grid or a conductive foil or a conductive layer. This offers the advantage that the stamped grid or the conductive foil or the conductive layer is designed to be as thin as possible and can therefore be easily preformed according to the contour of the housing or the insert. The insert can be optimized by allowing greater design freedom for the sensor carrier. This allows high actuating forces from the inside and outside to be absorbed in a more load-appropriate manner.

[0017] According to the above-mentioned design, the sensor carrier made of the punched grid or the conductive foil or the conductive layer can be overmolded or potted to form a plastic body in order to prevent contact with liquids or dirt.

[0018] The plastic body can be arranged on the inner housing wall or on the insert, in particular in a form-fitting and / or force-fitting and / or material-fitting manner, e.g. by gluing and / or screwing and / or clipping, and / or via a foam pad, so that no moisture can penetrate between the sensor and the inner housing wall or the insert, in order to eliminate the negative influence on the sensor.

[0019] Alternatively, it is conceivable that the sensor carrier is arranged directly on the inner housing wall or on the insert during assembly, in particular in a form-fitting and / or force-fitting and / or material-fitting manner, e.g. by gluing and / or screwing and / or clipping, and / or via a foam pad, so that no moisture can penetrate between the sensor and the inner housing wall or the insert, in order to eliminate the influence of moisture on the sensor, wherein the sensor carrier is sealed with plastic to prevent contact with liquid or dirt. For example, the sensor carrier can be subsequently encapsulated or covered by a cover configured for the sensor carrier.

[0020] In a special embodiment of the invention, the plastic body is designed as an element with a U-shaped cross section, or the sensor carrier is arranged on an element with a U-shaped cross section, whereby the U-shaped element can enclose the insert in a U-shape. This offers the advantage, if more than one sensor is present and the sensors are arranged both facing towards and away from the vehicle, that the sensors can be fastened together on a U-shaped element. This enables simple and intuitive installation, for example by sliding the sensor carrier around the insert from below and fastening it there.

[0021] If the actuating device has at least one sensor only on one of the sides facing away from or towards the vehicle, it is also conceivable, in order to save material, that the plastic body is designed as an element with an L-shaped cross section or that the sensor carrier is arranged on an element with an L-shaped cross section, whereby the L-shaped element can enclose the insert in an L-shape.

[0022] Within the scope of the invention, the sensor can be a proximity sensor which detects the user's actuation, in particular in the form of an approach, whereby the user's actuation triggers an opening signal and / or a locking signal for the door. According to one embodiment, the sensor can be designed as a capacitive sensor. An approach of the user to the actuation device is detected due to the change in the electric field in the environment in front of the sensor electrode. In addition to the sensor electrode, an edge shielding element can be arranged or integrated on or in the sensor carrier, which serves to adapt to environmental influences, for example liquids such as rain.

[0023] Within the scope of the invention, the sensor can also be a deformation recording sensor which detects the user's actuation action, in particular in the form of a touch, whereby the user's actuation action triggers an opening signal and / or a locking signal of the door.

[0024] One option for the strain sensor is a metal-over-cap (MoC) sensor. This sensor measures the change in distance based on a change in capacitance between the sensor and a metallic actuating element. The sensor acts as a measuring electrode, and the actuating element as a reference electrode. Thus, the user's force load is converted into a change in capacitance.

[0025] Alternatively, it is conceivable that the deformation recording sensor is an inductive sensor, whereby an actuation by the user generates an opening signal and / or a locking signal for the door. The change in position of an activating means relative to the sensor element leads to a change in inductance. For example, an oscillating circuit is evaluated with regard to the frequency in order to record the change in inductance. The force exerted by the user is converted into a change in inductance. Therefore, according to the two embodiments mentioned above, it is desirable for an electrically conductive activating means to be arranged on or in the housing, or to be motion-coupled to the housing in order to be moved relative to the sensor depending on the actuation by the user.For example, the sensor carrier, which is designed as a circuit board or a U-shaped element or has a plastic body and has a sensor (a MoC sensor or an inductive sensor), can have a distance (for example via an air gap or a spacer, e.g. in the form of a foam pad) from the activating means, wherein a conductive element is attached to the inner wall of the housing as a conductive layer or is designed to be movement-coupled to the housing. When the user acts, the distance decreases. It can be particularly advantageous for the sensor carrier to be supported against the insert so that the sensor carrier or the sensor remains stable and immobile under the force load. It is also conceivable for the sensor carrier to be a multi-layer circuit board, wherein both the sensor and the activating means are fastened in and / or on the circuit board.

[0026] It is also possible for the deformation sensor to be designed as a force sensor, in particular made of strain gauges, whereby the user's actuation triggers an opening signal and / or a locking signal for the door. In particular, the force sensor is arranged directly on the inner wall of the housing, thus enabling the user to exert a direct force on the actuating device.

[0027] Preferably, an NFC antenna carrier with an NFC antenna is also provided. An NFC antenna can either be formed as a single piece from the NFC antenna carrier or positioned separately on or in the NFC antenna carrier. The NFC antenna can be arranged next to the sensor in the vehicle's Z-direction.

[0028] Similar to the sensor carrier, the NFC antenna carrier can be a lead frame or a conductive foil. The sensor carrier, consisting of the lead frame, conductive foil, or conductive layer, can be overmolded or potted to form a plastic body to prevent contact with liquids or dirt.

[0029] It is also conceivable that the plastic body is arranged on the inner wall of the housing in a form-fitting and / or force-fitting and / or material-fitting manner, e.g. by gluing and / or screwing and / or clipping.

[0030] Alternatively, it is conceivable that the NFC antenna carrier is arranged directly, in particular with a form-fitting and / or force-fitting and / or material-fitting connection, on the inner wall of the housing during assembly, e.g., by gluing, screwing, or clipping, with the sensor carrier sealed by the plastic to prevent contact with liquids or dirt. For example, the NFC antenna carrier can be subsequently encapsulated or covered by a cover configured for the NFC antenna carrier.

[0031] In the actuating device according to the invention, it is preferably provided that an NFC antenna carrier is overmolded or cast in the plastic body of the sensor carrier, or that the NFC antenna carrier and the sensor carrier are one-piece. The sensor and the NFC antenna are combined in one component, which facilitates assembly and saves space in the housing. It is particularly advantageous in this embodiment that the NFC antenna and the sensor have a common shielding element, in particular in the form of a ferrite foil, which is arranged behind the NFC antenna and the sensor in the vehicle Y-direction, whereby the electromagnetic field or the detection direction of the sensor and / or the NFC antenna is directed. Alternatively, it is also sufficient if the shielding element, in particular in the form of a ferrite foil, is arranged only behind the NFC antenna.

[0032] Within the scope of the invention, the evaluation electronics can be designed as a printed circuit board, with the evaluation electronics being arranged vertically, horizontally, or diagonally in the housing. The optimal arrangement of the evaluation elements can be selected depending on the required shape of the actuating element and the corresponding available internal space.

[0033] Particularly stable positioning of the evaluation electronics is achieved when the evaluation electronics are arranged on the inner wall of the housing or on the insert, provided that the alignment of the evaluation electronics corresponds to the contour of the housing or the insert. Alternatively, a support element is conceivable which is arranged on the housing or on the insert, which is formed from the housing or from the insert, with the evaluation electronics being arranged on the support element. An additional support element offers greater flexibility for arranging the evaluation electronics.

[0034] In a further embodiment of the invention, it is conceivable that an inductive sensor is arranged on the evaluation electronics, which detects an actuation of the user, in particular in the form of a touch, whereby the actuation of the user triggers the opening signal and / or the locking signal of the door, wherein an electrically conductive activation means is arranged on or in the housing or is motion-coupled to the housing in order to be moved relative to the sensor depending on the actuation of the user. An alternative or additional possibility here is that the inductive sensor is arranged not on the sensor carrier, but directly on the evaluation electronics.Within the scope of the invention, the inductive sensor can also be replaced by a metal-over-cap (MoC) sensor which detects an actuation action of the user, in particular in the form of a touch, whereby the actuation action of the user triggers the opening signal and / or the locking signal of the door, wherein an electrically conductive activation means is arranged on or in the housing or is motion-coupled to the housing in order to be moved relative to the sensor depending on the actuation action of the user.

[0035] Further advantages, features, and details will become apparent from the following description, in which exemplary embodiments are described in detail, where appropriate with reference to the drawings. Identical, similar, and / or functionally equivalent parts are provided with the same reference symbols.

[0041] Fig. 1 shows a motor vehicle 1 with an actuating device 2 according to the invention on a handleless door 3, in which the present invention is implemented. An actuation by a user on the actuating device 2 triggers an opening signal and / or a locking signal for the door.

[0042] Fig. 2 shows a plan view of an actuating device 2 according to the invention in the vehicle Z direction. It can be seen that the housing 4 of the actuating device has three sections 5, 6 and V which have different spatial extensions in the vehicle Y direction. Between sections 5 and 6 and between sections 6 and 7 there are changes 8 in the spatial extension in the vehicle Y direction. Sections 5 and 7 with an increased spatial extension in the vehicle Y direction are designed for arranging the evaluation electronics units 9 (not visible in Fig. 2), while the sensor carrier 10 (not visible in Fig. 2) is placed in the middle section 6 with a reduced spatial extension in the vehicle Y direction. Fig. 3 provides a side view of the cross section of the actuating device 2 from Fig. 2 in the vehicle X direction to the outside of the motor vehicle 1 .The design concept described above can be seen in Fig. 3.

[0043] Fig. 3 shows a bending-resistant insert 11, which is made, for example, of steel and arranged in the housing 4. The insert 11 ensures sufficient rigidity so that the actuating device 2 can absorb high actuating forces from the inside and outside in a more load-appropriate manner. The insert 11 is provided as a conductor structure with a recess 12. The sensor carrier 10 is at least partially arranged in the recess 12 so that the actuating section of the actuating device 2 can be designed even flatter in the vehicle Y-direction.

[0044] Fig. 4 shows a plan view of a further actuating device 2 according to the invention in the vehicle Z direction. It can be seen that the housing 4 of the actuating device has two sections 13 and 14 which have different spatial extensions in both the vehicle Y direction and the vehicle Z direction. Between the sections 13 and 14 there is a change 8 in the spatial extension in the vehicle Y direction. The section 14 with an increased spatial extension in the vehicle Y direction is designed for arranging the evaluation electronics units 9 (not visible in Fig. 4), while the sensor carrier 10 (not visible in Fig. 4) is placed in the section 13 with a reduced spatial extension in the vehicle Y direction and which has an increased spatial extension in the vehicle Z direction. Fig.Fig. 5 provides a side view of the cross-section of the actuating device 2 from Fig. 4 in the vehicle Y direction towards the outside of the motor vehicle 1. In Fig. 5, the design concept described above can be seen.

[0045] Fig. 5 also shows a bending-resistant insert 11, which, compared to the insert 11 in Fig. 3, is constructed more solidly and is arranged in the housing 4. The insert 11 ensures sufficient rigidity so that the actuating device 2 can absorb high actuating forces from the inside and outside in a more load-appropriate manner. The sensor carrier 10 is arranged next to the insert in the vehicle's Y direction.

[0046] Fig. 6 shows the schematic sketch of the cross-sectional view in the vehicle X direction of a further actuating device 2 according to the invention. Similar to the actuating device 2 from Figs. 4 and 5, the housing 4 is divided into two sections 18 and 19 with different spatial extents in the vehicle Y direction. A bending-resistant insert 11 is also fastened in the housing 4. In the section with reduced spatial extent in the vehicle Y direction 18, a first sensor carrier 15 is arranged, in which a capacitive proximity sensor is formed as a single piece. The first sensor carrier 15 is formed from a punched grid. Other options such as a conductive foil or conductive layer are also conceivable. The sensor carrier is embedded in the plastic material to form a plastic body 20. The plastic body 20 is in turn glued and / or screwed and / or clipped to the inner wall of the housing.In addition to the sensor, an NFC antenna is also provided. The NFC antenna carrier 16 can be formed separately from the same stamped grid or together from the same stamped grid. The NFC antenna can be formed directly from the stamped grid. In Fig. 6, the NFC antenna carrier 16 is embedded in the same plastic body 20. The capacitive sensor and the NFC antenna are both directed towards the outside of the motor vehicle 1 facing away from the vehicle and share a common shielding element (not visible in Fig. 6). When the capacitive sensor detects approach, a door opening signal is triggered. On the other side to the insert 11, a second sensor carrier 17 is provided which has an inductive sensor. The inductive sensor can be attached to the sensor carrier 17 or can be formed as a single piece from the sensor carrier 17 (e.g. lasered if the sensor carrier 17 is a conductive foil).The sensor carrier 17 is embedded in the plastic material to form a second plastic body 21. The plastic body 21 is, for example, adhesively bonded and / or screwed and / or clipped to the insert 11 or to a mounting location 22 of the insert 11. An activation means 23 is arranged on the inner wall of the housing at a distance from the inductive sensor. When the user touches the corresponding location on the housing wall, the distance between the inductive sensor and the activation means 23 is reduced, thereby triggering a door locking signal. In the section with an enlarged spatial extent 19, an evaluation electronics unit 9 is arranged on the insert 11.

[0047] Fig. 7 shows the schematic sketch of the cross-sectional view in the vehicle X-direction of a further actuating device 2 according to the invention, which is constructed similarly to the actuating device from Fig. 6. The difference is that instead of an inductive sensor, the actuating device has a force sensor 24 in the form of strain gauges, which are arranged directly on the inner wall of the housing. The force load during the actuation by the user on the housing wall is converted directly by the strain gauges to a change in the electrical resistance and, after evaluation, a locking signal or an opening signal for the door is triggered.

[0048] Fig. 8 and Fig. 9 show two further examples of the actuating device 2 according to the invention with different arrangements of the evaluation electronics 9. In Fig. 8, the evaluation electronics 9 are fastened obliquely to the insert 11 in the housing. In Fig. 9, a support element 25 is formed from the insert 11, which supports the evaluation electronics 9. Fig. 9 also shows that an inductive sensor 26 is arranged directly on the evaluation electronics 9. An activation element 23 is arranged on the housing inner wall at a distance from the inductive sensor 26.

[0049] Fig. 10 shows a schematic sketch of the cross-sectional view in the vehicle X-direction of another actuating device 2 according to the invention. In Fig. 10, a U-shaped element for supporting the sensor carriers 15, 16, and 17, each on both legs of the U, is provided in the housing 4. The insert 11 is enclosed in a U-shape by the U-shaped element 27. Evaluation electronics 9 in the form of a printed circuit board is arranged in the lower region of the U-shaped element 27. This allows for simple and intuitive assembly, for example, by sliding the U-shaped element 27 around the insert from below and securing it there.

[0050] Fig. 11 shows a schematic diagram of the cross-sectional view in the vehicle X-direction of another actuating device 2 according to the invention. Unlike in Fig. 10, an L-shaped element 28 is used here instead of a U-shaped element 27, because it is only provided with sensors on the side of the housing facing away from the vehicle, which sensors are directed away from the vehicle. The above explanations of the embodiments describe the present invention exclusively within the framework of examples. Of course, individual features of the

[0051] Embodiments may be freely combined with one another, provided that this is technically feasible, without departing from the scope of the present invention.

[0052] It is understood that the features mentioned above and those yet to be explained below can be used not only in the combination specified, but also in other combinations or alone, without departing from the scope of the present invention. The scope of the invention is defined only by the claims.
