Description
Technical Field
The invention relates to an operating module for a motor vehicle, comprising a control unit, which comprises an input layer and a touch-sensitive input device, preferably in the form of a touch pad or a touch screen; a carrier element for providing a touch-sensitive input device; and a housing for movably arranging the carrying element and the operating unit.
Background
Operating modules for motor vehicles are known in the prior art, which have an operating unit that is arranged in a housing that is arranged in a center console or on a steering wheel. The manipulation unit has a touch-sensitive input device and an input layer. When the input layer is actuated, a haptic feedback is generated by the actuation module, after the user exerts a force on the input layer, for example by means of his finger. The touch-sensitive input device can be designed as a touch screen or as a touch pad. The operating unit can therefore comprise a multi-layer construction, i.e. a display pane designed as an input layer, an adhesive layer, a touch screen or touch pad, a frame for the arrangement of the touch screen and touch pad, and a carrier element. The force measurement is carried out directly at the carrier element, for example by inductive, optical or capacitive sensors. The use of a multi-layer design of the actuating unit for force measurement, such as a series connection of individual spring elements, is conceivable. The force generated by the user acts here when the spring elements are connected in series via all the spring elements in the composite part having the same value. Each spring element is therefore correspondingly elongated, so that the overall extension when the spring elements are connected in series is greater as a result of the connection as compared to each individual spring element, or a parallel connection of identical spring elements. Thus, in total, a softer overall spring element is obtained. Since the spring stiffness in the series connection of the spring elements is reduced overall, the length extension becomes greater when a force is applied. The length extension should trigger a haptic feedback if the user applies a force on the input layer. The haptic feedback is only performed when a force limit value, in particular a force threshold value, is reached. Accordingly, an accurate, in particular high local resolution, measurement of the respective forces is required. The requirement for the force measurement is that a force threshold of 1N to 5N should be achieved and this is the case for a maximum adjustment travel of 0.2mm to 0.8 mm. The predetermined value cannot be achieved by the known multilayer construction of the actuating unit.
Disclosure of Invention
It is an object of the invention to provide an operating module which reliably detects manipulations by a user in a compact configuration in order to generate haptic feedback for the user.
This object is achieved by claim 1, in particular by the characterizing features of claim 1. It is proposed that the carrier element is arranged in a supported manner on the input layer and that at least the touch-sensitive input device is at least partially, preferably completely, surrounded by the carrier element, wherein the carrier element and the housing are connected to one another by means of at least one restoring element, and the operating module has a sensor unit which detects a force acting between the carrier element and the housing and/or a distance between the carrier element and the housing.
According to the invention, the operating unit comprises a touch-sensitive input device. The term "touch-sensitive input device" is to be understood broadly. In this case, the components are generally associated with an input layer facing the user, on which the contact by the input means or the finger of the operator is detected with high local resolution by the sensor device. Preferably, the touch-sensitive input device comprises a touch panel, that is to say a display-less input device, which has a high-resolution detection of a contact on an input layer belonging to the input device, wherein in the latter case an electronic display, in particular an electronic pixel array display, is associated with the input layer.
If the user applies a force to the input layer of the operating module according to the invention, for example by means of his finger, this force can be reliably detected, since the entire carrier element is set in motion during operation. Direct application and transmission of force to the touch-sensitive input device, in particular to the touch pad or touch screen, is advantageously precluded. In the solution according to the invention, a direct introduction of force from the input layer into the carrier element is achieved, so that the carrier element is set in motion. In this way, it is advantageously ensured that a switching signal, which, for example, causes a haptic feedback, for example a vibration, of the touch-sensitive input device and/or of the input layer, can be triggered even when the adjustment travel of the actuating unit, in particular of the carrier element, is short (for example 0.2mm to 0.8mm) and the force exerted on the input layer is small (for example 1N to 5N). Thus, for example, a high local resolution detection of a contact with a tolerance of 5% to 10% can be provided by means of the operating module according to the invention. At least one reset element is used to move the carrier element back into the rest position after a user has operated the actuating unit.
The core idea of the solution according to the invention is therefore to conduct the force exerted by the user on the input layer on a direct path to the sensing unit via the carrying element.
In accordance with a preferred embodiment of the operating module, it can therefore be provided that a force exerted by the user on the input layer during operation can be introduced directly from the input layer into the carrier element without using a touch-sensitive input device, wherein the sensor unit detects the force acting between the carrier element and the housing and/or the distance between the carrier element and the housing. In the sense of the present invention, the transmission of the forces generated during operation from the input unit into the carrier element without the use of a touch-sensitive input device means that either no forces are introduced into the touch-sensitive input device at all or the forces introduced into the touch-sensitive input device during operation are so small that they have a small influence on the sensor unit. This is achieved, for example, in that the connection between the input layer and the carrier element is stiffer under the action of a vertical pressure than the connection between the input layer and the touch-sensitive input device. It is illustrated that the total stiffness of the system of input layer, carrier and touch-sensitive input device can be understood in this case as a parallel connection of the spring elements, which is ideally dominated by the stiffness of the connection between the input layer and the carrier element.
If the sensor unit has at least one first sensor section and one second sensor section, the first sensor section being arranged on the carrier element, in particular on the rear wall of the carrier element, and the second sensor section being arranged on the housing, the sensor unit can be arranged very space-effectively and compactly in the operating module. Thus, a sensor unit can be advantageously used, which can detect a movement of the carrier element relative to the housing.
If the carrier element, in particular the rear wall, is designed as a first sensor section, the operating module can have a simple and compact design. This measure reduces the number of components, since additional sensor sections for the carrier element can be dispensed with. The carrier element thus has two functions. In one aspect, the carrier element is at least used to set and mount a touch-sensitive input device. On the other hand, the carrier element, in particular the rear wall thereof, serves as part of the sensor unit. In this case, it may be expedient for the support element to be made of metal, preferably of a metal injection-molded part, which contains Mg and Zn. In particular in electromechanical sensors, which are also described in more detail below, a low-cost construction of the sensor unit can be provided. Furthermore, the carrier element, which is preferably designed as a metal injection molding, serves for: reliable electromagnetic compatibility shielding and electrostatic protection shielding of the manipulation unit can be ensured. Furthermore, the carrier element protects the touch-sensitive input device against contamination and/or moisture, which is preferably completely surrounded by the carrier element.
According to a further preferred embodiment of the operating module, it can be provided that the carrier element is connected to the actuating unit, in particular to the input layer, in a material-fit and/or force-fit and/or form-fit manner. In this case, it may be suitable to bond, clamp, lock or screw the carrier element and the input layer together, for example. However, it should always be ensured that the carrier element is supported relative to the input layer in order to introduce forces exerted on the input layer into the carrier element when the actuating unit is actuated without using a touch-sensitive input device. The operating module according to the invention has a compact structural design, since the carrier element is simply connected in a secure and sealed manner to the glass input layer material of the actuating unit in a form-fitting and/or force-fitting and/or form-fitting manner.
Furthermore, the carrier element, in particular the rear wall of the carrier element, is designed for providing at least one restoring element, which is preferably designed as a spring element. At least one reset element is used to move the carrier element back into the rest position after a user has actuated the actuating unit. The construction of the operating module can therefore be very simple and cost-effective when the at least one restoring element is designed as a spring element.
The input layer can be connected to the touch-sensitive input device, for example, by means of an adhesive. If the touch-sensitive input device is designed as a so-called touch screen, the touch screen can be connected to the input layer, in particular, by means of an optically transparent adhesive (so-called optical bonding). It is to be noted here that the adhesive connection between the input layer and the touch-sensitive input device is softer than the connection between the input layer and the touch-sensitive input device. For example, the shore hardness 00 (according to DIN ISO53505 after 72 hours room temperature) of the adhesive connection between the input layer and the touch-sensitive input device is less than 90, preferably less than 70 and more preferably less than 50. For example, adhesives for adhesive bonding are based on acrylate and harden under the action of light and/or moisture and/or heat.
Very reliably, the touch-sensitive input device can be arranged in the operating module when the touch-sensitive input device is mounted in a frame element which is connected to the carrier element and/or the actuating unit. The frame element is preferably made of plastic, so that the frame element can be used as a plastic frame for receiving a touch-sensitive input device.
In order to protect the touch-sensitive input device arranged in the carrier element against dust and dirt, it can be provided that the touch-sensitive input device is surrounded by a protective element which is connected to the carrier element and/or the frame element. Another function of the protective element, which is preferably made of aluminum, is that the protective element isolates light from the outside. The touch-sensitive input device is preferably arranged at a distance from the protective element.
A secure and secure connection of the carrier element to the actuating unit can be ensured if the carrier element and the actuating unit, in particular the input layer, are connected to one another by means of at least one first adhesive element.
Likewise, if the frame element is connected with the touch-sensitive input device by means of the at least one second adhesive element, a secure and secure connection between the frame element and the touch-sensitive input device can be provided.
The production of the actuating unit can be greatly simplified if the first adhesive element and/or the second adhesive element is designed as a tape, preferably as a double-sided tape or as a liquid adhesive which hardens after a predetermined time. The production costs can be further reduced, in particular by means of the double-sided adhesive tape, since this can be easily installed by the worker.
According to a further preferred embodiment of the operating module, in particular of the actuating unit, it can be provided that a black printing layer is arranged between the actuating unit, in particular the input layer, and the adhesive element. A circumferential decorative frame can be produced on the input layer of the actuating unit by means of a black-printed layer. The use of a black printing layer is likewise very advantageous, since the connection between the carrier element and the actuating unit maintains its reliable adhesive action. The black printing layer is applied thinly on the input layer or is designed such that it has no influence on the transmission of force from the input layer to the carrier element, so that even in the case of the use of a black printing layer arranged between the input layer and the carrier element, forces are introduced directly from the input layer into the carrier element during operation.
According to a further preferred embodiment of the operating module, it can be provided that the sensor unit is designed as a capacitive sensor, wherein the first sensor section and the second sensor section are each made of metal. The capacitive sensor can be embodied, for example, as a plate capacitor. In this case, the rear wall of the carrier element, which is made of metal, can form a first plate and the second sensor section, which is made of a metal film, for example, forms a second plate, wherein the second sensor section is preferably arranged on the housing. If, for example, the rear wall of the support element, which is made of metal, approaches the metal film when the actuating unit is actuated by a user, the change in capacitance of the plate capacitor is detected by measuring the change in voltage.
Alternatively or additionally, it can be provided in the operating module according to the invention that the sensor unit is designed as an inductive sensor, wherein the first or second sensor section comprises a coil and the first or second sensor section is made of metal, wherein a voltage is induced when the first sensor section is in emergency with the second sensor section. For example, eddy currents are induced in the rear wall of the carrier element and the inductive coupling is measured by means of the sensor unit. It can also be provided that at least one, in particular cylindrical, chamber is provided on the carrier element, preferably on the rear wall of the carrier element, in which chamber an inductive coupling is generated and/or measured. For example, it can be provided that the coil is arranged on the housing. If a force is applied to the input layer when the actuating unit is actuated by a user, the rear wall made of metal moves toward the coil, so that the distance between the coil and the rear wall changes. The inductive coupling thereby changes and the force exerted when the actuating unit is actuated by the user can be inferred.
Alternatively or additionally, it can be provided in the operating module according to the invention that the sensor unit is designed as a light sensor, wherein the first sensor section or the second sensor section comprises at least one light source which generates a light beam, wherein the light beam is reflected by the carrier element, in particular the first sensor section or the housing, in particular the second sensor section. In the case of the optical sensor unit, it can be provided, for example, that the light source emits a light beam, in particular a laser beam, at the housing and that the light beam is reflected by the rear wall of the carrier element. In this case, the intensity and/or the operating time of the light beam can be measured. If the carrier element, in particular the rear wall of the carrier element, approaches the light source when the operating unit is operated by the user, the intensity and/or the operating time of the light beam can then be deduced from the force exerted when the operating unit is operated by the user. It is of course also conceivable for the light source to be arranged on the carrier element, in particular on a rear wall of the carrier element.
If the input layer consists of glass, in particular of chemically pre-hardened glass from the group of alumino-silicate glasses, the forces exerted on the input layer can be reliably introduced into the carrier element.
The invention also relates to the use of an operating module in one of the previously described embodiments in a motor vehicle. In this case, it can be provided that the housing is a component of a console or of a steering wheel. It is also conceivable for the housing to be designed as a separate component which can be inserted into a receiving section of the motor vehicle, which is provided, for example, in the center console or at the steering wheel.
Drawings
The invention and the technical environment are explained in detail below with reference to the drawings. It is to be noted that the figures show particularly preferred embodiment variants of the invention, to which the invention is not restricted. The figures show:
fig. 1 shows a schematic cross-sectional view of an operating module according to the invention; and
fig. 2 shows an isometric view of the handling unit and the carrier element of the operating module according to the invention from above.
Detailed Description
Fig. 1 schematically shows an operating module 1 according to the invention for a motor vehicle. The operating module 1 has a control unit 2, which is shown in fig. 2. Furthermore, the operating module 1 comprises a sensor unit having at least one first sensor section 3 and a second sensor section 4. Furthermore, the operating module 1 has a housing 5 for the displaceable arrangement of the carrier element 9. It can be provided here that the housing 5 is, for example, a component of a dashboard or of a steering wheel of a motor vehicle. It is also conceivable for the housing 5 to be designed as a separate component which can be inserted into a receiving section of the motor vehicle, for example in the center console or at the steering wheel.
The actuating unit 2 comprises at least one input layer 7 and a touch-sensitive input device 8, wherein the touch-sensitive input device 8 is arranged completely within a carrier element 9 made of metal, in particular a metal die cast part comprising Mg or Zn, which has a rear wall 10. The input layer 7 is preferably made of glass, in particular chemically pre-hardened glass from the group of alumino-silicate glasses.
The touch-sensitive input device 8 can be designed as a touch screen or touch pad, to which the input layer 7 is associated. The input layer 7 can be connected to a touch-sensitive input device 8, for example, by means of an adhesive. If the touch-sensitive input device 8 can be designed as a so-called touch screen, it is connected to the input layer 7, in particular by means of an optically transparent adhesive (so-called optical bonding). The adhesive layer 35 is formed by an optically transparent adhesive, which connects the touch-sensitive input device 8 and the input layer 7 to one another. It is to be noted here that the adhesive layer 35 between the input layer 7 and the touch-sensitive input device 8 is softer than the connection 12 between the input layer 7 and the carrier frame 9. For example, the adhesive connection between the input layer 7 and the touch-sensitive input device 8, in particular the shore hardness 00 of the adhesive layer 35 (according to DIN ISO53505 after 72 hours at room temperature), is less than 90, preferably less than 70 and more preferably less than 50. For example, the adhesive of the adhesive connection, in particular of the adhesive layer 35, is based on acrylate and hardens under the action of light and/or moisture and/or heat.
Furthermore, the carrier element 9, which is preferably formed by a metal injection molding, serves to ensure a reliable electromagnetic compatibility shielding and electrostatic protection shielding of the operating module 1, in particular of the actuating unit 2.
The touch-sensitive input device 8 is connected to a connection cable 11, which is designed, for example, for transmitting data and/or for supplying energy.
A carrier element 9 is supported on the input layer 7, wherein a force applied to the input layer 7 when actuated by a user can be introduced directly from the input layer 7 into the carrier element 9 without using a touch-sensitive input device 8. The sensor unit detects the force acting between the carrier element 9 and the housing 5 and/or the distance between the carrier element 9 and the housing 5. Therefore, the distance between the first sensor section 3 and the second sensor section 4 is preferably changed and the switching signal is triggered.
The support element 9 is to be connected to the actuating unit 2, in particular to the input layer 7, in a material-and/or force-and/or form-fitting manner. In this case, it may be suitable to bond, clamp, lock or screw the carrier element 9 to the input layer 7, for example, or to plug them into one another. However, it should always be ensured that the carrier element 9 is supported relative to the input layer 7 in order to introduce forces exerted on the input layer 7 when the touch-sensitive input device 8 is operated directly into the carrier element 9 without using the touch-sensitive input device 8. Thus, during the operation of the actuating unit 2, substantially no force transmission takes place from the touch-sensitive input device 8 to the sensor unit, in particular to the carrier element 9, which could affect the mode of operation of the sensor unit.
The carrier element 9 can comprise the first sensor section 3, wherein in the present case the rear wall 10 preferably forms the first sensor section 3. Alternatively, the first sensor section 3 can also be formed as a separate component, for example as a metal film, which is arranged on the carrier element 9. The housing 5 comprises a second sensing section 4. The carrier element 9 and the actuating unit 2, in particular the input layer 7, are connected to one another by means of at least one first adhesive element 12. The first adhesive element 12 is designed as a tape, preferably as a double-sided tape. Alternatively, a liquid adhesive that hardens after a certain time can also be used as the first bonding element 12. A black printing layer 30 is arranged between the actuating unit 2, in particular the input layer 7 and the first adhesive element 12, which black printing layer is visible to the user on the input layer 7, for example as a circumferential decorative frame. The adhesive element 12 has a shore hardness 00 (according to DIN ISO868) of more than 50, preferably more than 70 and more preferably more than 90.
The touch-sensitive input device 8 is mounted on a frame element 13, which is connected to the carrier element 9 and/or the actuating unit 2, preferably in a material-fit and/or force-fit and/or form-fit manner. The connection between the touch-sensitive input device 8 and the frame element 13 is realized here by means of a second adhesive element 14. The second adhesive element 14 is designed as an adhesive tape, preferably as a double-sided adhesive tape. Alternatively, the second adhesive element 14 may comprise a liquid adhesive which hardens after a predetermined time.
Furthermore, the touch-sensitive input device 8 is surrounded by a protective element 15, which is made of aluminum and is connected to the carrier element 9 and/or the frame element 13. The protective element 15 is connected to the carrier element 9 by means of a force-fitting and/or form-fitting connection, wherein in the present case the protective element 15 and the carrier element 9 are connected to one another by means of a screw 16. The touch-sensitive input device 8 is preferably arranged at a distance from the protective element 15.
Furthermore, the housing 5 and the carrier element 9 are connected to at least two restoring elements 17, 18, which serve to return the actuating unit 2 to its initial position, in particular to a rest position, after the actuating unit 2 has been actuated.
As can be clearly recognized in fig. 1, different sensing units are shown. Preferably, only one type of sensing unit is used. It goes without saying that it is also possible to use different types of sensor units, for example in order to obtain a redundant sensor system. Therefore, in the case where the sensor unit stops operating, the operation of the manipulation unit 2 can be reliably detected.
For cost reasons, the operating module 1 should have only one sensor unit.
In fig. 1, a capacitive sensor is shown, which is formed by a first sensing section 3 and a second sensing section 4. The rear wall 10 of the carrier element 9, which is made of metal, can form a first plate and the second sensor section 4, which is made of a metal film 19, for example, forms a second plate, which is arranged on the housing 5. If the rear wall 10 of the support element 9, which is made of metal, for example, approaches the metal film 19 when the actuating unit 2 is actuated by a user, the change in capacitance of the plate capacitor is detected by measuring the voltage change, and the force exerted when the actuating unit 2 is actuated by the user can be inferred on the basis of the detection of the voltage change.
Fig. 1 shows a further sensor unit, wherein the sensor unit is designed as an inductive sensor, wherein the second sensor section comprises two coils 20, 21 spaced apart from one another, and the first sensor section 3, in particular the rear wall 10 of the carrier element 9, is made of metal, wherein the distance between the first sensor section 3 and the second sensor section 4 changes when they approach one another and a voltage is induced in the latter. For example, eddy currents are induced in the rear wall 10 of the carrier element 9 and the inductive coupling is measured by means of a capacitive sensor unit. Furthermore, it can be provided that two, in particular cylindrical chambers 22, 23 are preferably provided on the carrier element 9, preferably on the rear wall 10 of the carrier element 9, in which chambers an inductive coupling is generated and/or measured in each case. Thus, the coils 20, 21 are provided on the housing 5. If a force is exerted on the input layer 7 when the actuating unit 2 is actuated by a user, the rear wall 10 made of metal is moved toward the coils 20 and 21, so that the spacing between the coils 20, 21 and the rear wall 10 changes. The inductive coupling thereby changes and the force exerted when the actuating unit 2 is actuated by the user can be inferred.
The operating module 1 according to the invention furthermore has an optical sensor unit in the form of a light sensor, wherein the second sensor section 4 comprises at least one light source 25 which generates a light beam 24, wherein the light beam 24 is reflected by the carrier element 9, in particular the first sensor section 3. In the case of an optical sensor unit, for example, it can be provided that a light source 25 arranged on the housing 5 emits a light beam 24, in particular a laser beam, and that said light beam is reflected by the rear wall 10 of the carrier element 9. Here, the intensity and/or the running time of the beam 24 may be measured. If the carrier element 9, in particular the rear wall 10 of the carrier element 9, approaches the light source 25 when the operating element 2 is operated by the user, the intensity and/or the operating time of the light beam 24 changes and thus the force exerted when the operating element 2 is operated by the user can be inferred. It is of course also conceivable for the light source 25 to be arranged on the carrier element 9, in particular on the rear wall 10 of the carrier element 9.
