[0106] The module component 100 is configured for actuating, i.e., unlocking, opening, locking, and/or closing, the movable part 201. A movable part 201 may be, for example, a door or a flap of the vehicle 200. The vehicle 200 as a whole is not shown in the figures merely for simplicity. The vehicle 200 or the movable part 201 of the vehicle 200 is only indicated in
[0107] The module component 100 is configured as an individually manageable, coherent module component which, after assembly as a whole, can be mounted at an intended location on the vehicle 200. The module component 100 preferably serves as an electronic device of modular configuration with sensor devices 31, 32 integrated in terms of function as well as circuitry and a lighting device 33, which can also be referred to as an illumination device, as well as a support housing 10 for direct fastening of the module component as a whole. Within the scope of the invention, it is conceivable that the module component 100 can be fastened to a fixed handle, a grip recess 201M and/or an outer skin of the movable part and/or to a component of the vehicle 200 adjacent to the movable part 201.
[0108] In one aspect, the module component 100 includes: [0109] a support housing 10 shown in
[0110] The support housing 10 may also be referred to as an assembly support. The support housing 10 is configured for fastening the module component 100 to the movable part 201 of the vehicle 200. In addition, the support housing 10 is configured for movably supporting a key device 20 (cf.
[0111] The module component 100 includes, in another aspect: [0112] a key device 20 for actuating the movable part 201 of the vehicle 200, which is shown in a stand-alone position in
[0113] The key device 20 is further shown in
[0114] The key device 20 comprises a key cap 21, in particular fixed or dimensionally stable and transparent (for light in the visible spectrum or at least for light in the light spectrum of at least one lighting device 33), which is configured to be wholly or partially movable relative to the support housing 10. The key cap 21 may be fastened to the support housing 10 by a sealing element 22. The sealing element 22 may further be compressible and/or serve as a resilient bearing element. The key cap 21 serves to be able to mechanically receive an activation action of a user, for example in the form of touching and/or applying force, such as pressing, to the key cap 21. The key cap 21 may be configured to be deformable as a whole or in part for receiving the activation action. Advantageously, the key cap 21 may comprise at least one deformation region. An actuation movement of approx. 0.01 mm to 0.02 mm can be sufficient to receive the activation action.
[0115] As shown in
[0116] The module component 100 further comprises: [0117] An electronic device 30 for providing lighting functions as well as sensor functions when the movable part 201 of the vehicle 200 is actuated.
[0118] As indicated by
[0119] Furthermore, as can be seen in
[0120] The lighting device 33 serves to provide a lighting function on the module component 100, which facilitates the actuation of the movable part 201.
[0121] In the scope of the invention, the lighting device 33, together with the sensor device 31, 32 for a presence detection and/or an activation action detection, is functionally as well as circuitry integrated within the electronic device 30. The module component 100, in the sense of the invention, comprises a compact structure and performs not only the sensor functions but also the lighting functions when the movable part 201 is actuated.
[0122] The electronic device 30 can, for example, first detect a presence and/or an approach and/or a certain movement pattern of a user. For this purpose, a capacitive sensor device 32 of the electronic device 30 may serve, which is schematically indicated in
[0123] Thereafter, the electronic device 30 can initiate an identification check in the sense of the invention (for example, with the aid of an on-board communication device 202, which is schematically indicated in
[0124] With the lighting device 33 turned on, the user can easily locate the key cap 21 to actuate the key cap 21 and eventually the movable part 201.
[0125] For actuating the movable part 201, such as for unlocking and possibly automatically opening the movable part 201, the electronic device 30 in the sense of the invention can transmit corresponding control commands to an on-board control apparatus 203, which is schematically indicated in
[0126] As indicated in
[0127] As already mentioned above and as can be seen in
[0128] The activation element 24 can, for example, have a material thickness of approximately 0.1 mm to 0.5 mm, for example 0.2 mm.
[0129] The activation element 24 can be fastened to an inner side 211 of the key cap 21, for example, through a support plate 23. The support plate 23 can have a material thickness of approximately 0.2 to 2 mm, in particular 0.3 to 1.5 mm.
[0130] In addition, it is conceivable that activation element 24 can be formed, for example, in the form of an electrically conductive coating, for example, on a support plate 23 or directly on an inner side 211 of the key cap 21.
[0131] The activation element 24 can serve as a movable metallic element for an inductance measurement in an inductive sensor device 31, for example in the form of an LDC sensor, for an activation action detection.
[0132] Further, the activation element 24 may serve as a capacitive sensing electrode for presence detection in a capacitive sensor device 32 and/or capacitive evaluation electronics 32.
[0133] Since the activation element 24 is fastened to the key cap 21, it can be moved with the key cap 21 as a whole and/or with a deformation region on the key cap 21. Movement of the activation element 24 relative to the sensor device 31, 32 causes a measurable change in inductance in the sensor device 31, 32.
[0134] As shown in
[0135] The air chamber K is closed off and in particular sealed by the attachment of the key cap 21 on the one hand and the electronic device 30 on the other hand to the support housing 10. The sealing element 22 can be used for sealing from the outside (cf.
[0136] In the air chamber K, the light L from the at least one lighting device 33 can propagate before it enters the key cap 21, is guided through it, possibly shaped and/or scattered and/or aligned, and exits the key cap 21 to the outside with respect to the air chamber K. In this way, a protected mounting of the at least one lighting device can be made possible. Also, lighting functions with improved, individually adjustable properties can thereby be provided.
[0137] From
[0138] Advantageously, a plurality of activation elements 24, for example two activation elements 24, may be arranged on the key cap 21 to be able to detect the activation action of the user. In this way, the activation elements 24 can be configured without through holes 24A for the lighting devices 33.
[0139] It is further apparent from
[0140] As can be seen in
[0141] In
[0142] After fastening the key cap 21 and the electronic device 30 to the support housing 10, the activation element 24 comes to rest resiliently on the free-standing contact element 34, for example in the form of a leaf spring contact, of the electronic device 30 and thus contacts the electronic device 20, in particular a capacitive evaluation device 32 of the electronic device 20. The contacting of the activation element 24 with the capacitive evaluation device 32 can preferably serve for presence detection.
[0143] In
[0144] As indicated by
[0145] Furthermore,
[0146] The rough structure 21R can be produced, for example, by roughening the outer side 21A of the key cap 21.
[0147] The rough structure 21R may not only scatter the light L from the at least one lighting device 33, but also provide a haptic tactile sensation for better haptic location of the key cap 21, especially when, felt in a grip recess.
[0148] Further,
[0149] In addition,
[0150] The area of the circumferential gap S can preferably be filled by a sealing element 22, in particular by a folding region 22f of the sealing element 20 (cf.
[0151] In principle, it is conceivable within the scope of the invention that the sensor device 31, 32 can comprise at least one or more inductive sensor devices 31, e.g. in the form of LDC sensors, arranged symmetrically to one another (cf.
[0152] In addition, the sensor device 31, 32 can comprise a capacitive sensor device 32 and/or a capacitive evaluation device 32 for presence detection at the activation element 24. With the help of capacitive sensor devices, a presence detection in the range of several meters up to several hundred meters can be detected.
[0153] The electronic device 30 comprises a control device 35 (cf.
[0154] The control device 35 may, for example, after a positive presence detection and/or a positive identification check of the user at the activation element 24, turn on an illumination of the key cap 21 to facilitate locating the key cap 21.
[0155] As indicated by
[0156] As indicated by
[0157] As shown in
[0158] As mentioned above, the electronic device 30 may be arranged from an inner side 101 of the support housing 10 on the support housing 10, in particular at an opening 11 in the support housing 10, preferably behind the key cap 21, and/or may be potted with a potting compound to fasten and/or seal the electronic device 30.
[0159] As mentioned above, a sealing element 22 may be arranged on the key cap 21 to seal an opening 11 in the support housing 10 and, in particular, to protect the electronic device 30 from the effects of the weather.
[0160] The sealing element 22 may also be configured to fix the key cap 21 to the support housing 10, preferably to an opening 11 in the support housing 10, in particular by a laser welding process, and/or to fasten and/or support it in a movable manner, in particular by compressibility of the sealing element 22, so that it can be pressed in at least slightly.
[0161] According to a particular advantage, the sealing element 22 may be configured to allow a volume compensation, in particular in an air chamber K, between the key cap 21 and the electronic device 30.
[0162] As indicated by
[0163] Furthermore,
[0164] Furthermore, as can be seen in
[0165] The key cap 21 and the sealing element 22 can be configured as a 2-component injection-molded component. In this case, the key cap 21 and the sealing element 22 or the seal element 22, preferably at a fastening region 22b, can be fastened to the support housing 10 by material bonding, in particular by laser welding, in order to fasten the key device 20 to the support housing 10.
[0166] As shown in
[0167] A method according to the invention for manufacturing a module component 100 for a movable part 201 of a vehicle 200 comprises the following steps/stages: [0168] Providing a support housing 10 for fastening the module component 100 to the movable part 201 of the vehicle 200, and in particular for movably supporting a key device 20 and preferably for fastening an electronic device 30 (cf.
