    [0001] Description Electronic module comprising an integrated electronic sensor element, in particular for a gearbox control device.
    [0002] FIELD OF THE INVENTION The present invention relates to an electronic module such that it can in particular be implemented for a set of sensor-sensors, which can be used in the production of a gearbox control device in a vehicle. automobile.
    [0003] State of the art Electronic modules are generally used to make electrical control circuits. The electrical control circuits can in this case, for example be part of a control device. Particularly in the field of automotive construction, electronic modules are used to produce control devices of the vehicle. In an electronic module are typically provided, on a printed circuit board element, also referred to as platinum or printed circuit board, a plurality of electronic components, which are electrically connected or interconnected with each other by means of conductive tracks. . In particular for gearbox control devices in a motor vehicle, it may be advantageous to arrange an appropriate electronic module in an area in which it is exposed to aggressive fluids and agents. An electronic module of a gearbox control device can for example be arranged inside a gearbox of a motor vehicle, or chemically aggressive gearbox oil, dirt or chips. In particular, they may come into contact with the electronic module. As at least parts of the components, conductive tracks, etc., provided on the electronic module are sensitive to such aggressive agents or fluids or particles, it may be necessary to protect them with a hermetically sealed housing. Electronic modules are often also used to measure, with the aid of detector elements, variable physical quantities. In this case, a detector element can be arranged separately, ie outside the electronic module, and be electrically connected to it. Alternatively, a sensor element may be integrated inside the electronic module. In the case of a sensor element arranged outside, an additional implementation may be necessary to ensure the electrical interconnection thereof with electronic components of the electronic module. In the case of a detector element integrated in the electronic module, it may be difficult to configure or even arrange the detector element so as to reliably measure variable quantities outside the hermetically sealed electronic module. . DESCRIPTION AND ADVANTAGES OF THE INVENTION According to embodiments of the present invention, there is provided an electronic module, a set of sensor-sensors comprising such an electronic module, and a gearbox control apparatus comprising such an electronic module. , in which, on the one hand, a detector element can advantageously be protected against an influence, for example of aggressive agents, and the detector element can, on the other hand, be designed and arranged in such a way as to ability to accurately and reliably measure variable quantities to the extreme. According to a first aspect of the invention, there is provided an electronic module, which comprises a printed circuit board element with at least one electronic sensor element, and a cover element. The printed circuit board element and the cover element together enclose a receiving housing in which at least one electronic sensor element is arranged. The electronic module is characterized in that the cover element has at least one protrusion for locally enlarging the receiving housing, and the detector element is housed at least partly in the protrusion. According to a second aspect of the invention, there is provided a set of detector-sensors, which comprises an embodiment of the electronic module according to the first aspect of the invention, as well as a sensor element for producing a sensor signal. detector when the sensor element is moved in front of the sensor element. The sensor-sensor assembly is here designed so that the sensor element is brought, during the operation of a unit to be monitored, to be moved in the immediate vicinity of the protrusion of the lid member of the electronic module. Furthermore, there is provided a gearbox control apparatus comprising an electronic module according to said first aspect, and a gearbox control respectively comprising a set of sensor detectors according to said second aspect. Ideas relating to the aforementioned aspects of the invention may, among other things, be considered as being based on the findings and principles described below. As has been described in the introduction, electronic modules, for example for gearbox control devices, are often made as sealed modules, in particular encapsulated modules, in which electronic components are housed in the hermetically sealed interior of the transmission. module. An implantation space within such an electronic module is typically narrow, so that the detector elements must heretofore either be housed integrally in the narrow implantation space by not being thus possibly not oriented optimally, or be arranged separately and then be wired with electronic components provided inside the module. At present, it is proposed, in an electronic module having at least one printed circuit board element and a cover element, which together enclose a receiving housing and, where appropriate in common with other elements, make the receiving housing hermetically sealed against an environment, to configure the cover member in a special manner, thereby to allow an advantageous arrangement of detector elements. For this purpose, protrusions are provided on the lid element.
    [0004] An outgrowth may here designate a geometric configuration of the cover member, with the aid of which the receiving housing may be partially enlarged or enlarged locally. In the region of an outgrowth, the cover member can thus be convexly curved locally outwardly. In the enlarged receiving housing in the region of the protrusion, a sensor element can then be suitably arranged. A protrusion here can be suitably configured, so that the sensor element to be arranged therein on the one hand finds sufficient space and can be arranged in a desired position and / or orientation, and on the other hand The sensor element can be appropriately maintained in the region of the protuberance. The protrusion and the detector element to be arranged thereon can advantageously be configured so that the detector element can be arranged in such a way that it can measure in a simple manner and with sufficient precision, magnitudes physical measuring devices, such as those that can for example be produced in a variable manner by a movable sensor element outside the electronic module.
    [0005] The cover member may have in a zone of an outgrowth, a lower thickness than in neighboring areas. This allows, among other things, the detector element arranged in the protrusion, to be better able to detect through the cover element.
    [0006] By way of example, a variable magnetic field, which is for example produced by a sensor element moving outside the electronic module, can pass more intensely through the thinned zone of the lid element, close to the protrusion, and then be detected by the detector element housed in the protrusion. The cover member can be made as a plastic part. Such a plastics piece can, on the one hand, serve, in common with the printed circuit board element, to enclose the receiving housing in a hermetically sealed manner. A cover element made of plastic material can here be manufactured simply and economically. It may for example be in the form of a piece of plastic injection molded. On the other hand, the cover element made in the form of a plastic part generally makes it possible to detect, for example, a measurement quantity to be measured, such as a variable magnetic field. In particular, the material of the cover element may be chosen so that, for example, a field to be measured is intensely transmitted, that is to say, it is not absorbed or reflected.
    [0007] Alternatively, the cover member may be formed as a part of a non-magnetic metallic material. A detector element housed therein can detect through the non-magnetic metallic material, for example magnetic fields, which vary outside the electronic module. The metal cover member may for example be integral, and may be obtained from a sheet, by folding, drawing, stamping, cutting or the like. The cover member and the printed circuit board member can be configured and interconnected such that they alone already enclose and seal the receiving housing against external influences. Alternatively, additional elements, such as a frame member or other plate member, may be provided to completely enclose, in a hermetically sealed manner, the receiving housing, together with the cover member and the housing element. printed circuit board. The sensor element can be fixed in the associated protrusion. In other words, the sensor element can not only be accommodated in the protrusion, but can also be fixed by appropriate measures. For example, it is possible that dimensions of the sensor element and the protrusion are mutually adapted so that the sensor element is held in the protrusion by a force fit. The sensor element can also be held tight or otherwise by a suitable configuration of the protuberance or clamping elements provided therein.
    [0008] According to a special configuration, the sensor element may be attached to a separate printed circuit board sub-element, and the printed circuit board sub-element may protrude transversely from the printed circuit board element. In other words, the detector element can itself be arranged on an additional printed circuit board partial element, generally smaller than the printed circuit board element itself, and this partial element of The printed circuit board may be arranged inside the electronic module in a different orientation than the printed circuit board element. In this way, the sensor element can be arranged in a position and an orientation adapted to its measuring function, independently of the position and orientation of the printed circuit board element. In this case, the partial element of printed circuit board can be flexibly attached to the printed circuit board element. For this purpose, the printed circuit board partial element can be fixed to the printed circuit board element, for example by means of a flexible partial area, which can in particular be folded. The flexible partial area may here for example be a thinned area of a printed circuit board partial element where the printed circuit board partial element can be simply bent. With such a flexible attachment, it is possible on the one hand to obtain reliable mechanical and / or electrical attachment of the printed circuit board partial element to the printed circuit board element, and on the other hand the detector element arranged on the printed circuit board partial element may be arranged in a suitable position / orientation with respect to the printed circuit board element. It should be noted that the possible characteristics and advantages of configurations of the invention are here described with reference in part to an electronic module and in part to a set of sensor-sensors, a gearbox control device or a gearbox. gearbox control. Those skilled in the art are able to see that it is possible to combine or exchange the evoked features appropriately to achieve other embodiments of the invention. Drawings In the following, embodiments of the invention will be described with reference to the accompanying drawings, neither the description nor the drawings are to be considered as limiting the invention. - Figure 1 shows a sectional view of an electronic module of a gearbox control apparatus. - Figure 2 shows a sectional view of an electronic module according to the invention. - Figure 3 shows a sectional view of an alternative configuration of an electronic module according to the invention. The figures are only schematic and do not respect the scales. Identical references designate identical characteristics or identical action in the different figures. DESCRIPTION OF EMBODIMENTS OF THE INVENTION FIG. 1 shows a traditional electronic module 1, such that it can be implemented for the implementation of gearbox control devices for motor vehicles. A printed circuit board member 3, a cover member 5, and a frame member 7 arranged therebetween, enclose a receiving housing 9 for components. The printed circuit board element 3 is connected to the frame element 7 along a ring-shaped peripheral zone 11, the connection being fixed in a mechanically fixed and hermetically sealed manner. For this purpose, in the printed circuit board element 3, most often made of a thermosetting material, is formed a micro-structuring 13 for which, in the peripheral zone 11 of the printed circuit board element 3, micro-cavities have been produced, for example using laser machining. The frame element 7, which is typically made of a thermoplastic material, may, for its connection with the printed circuit board element 3, be temporarily heated in a boundary zone and thus be liquefied or plasticized, so that the material thermoplastic element of the frame member 7 can engage in the microcavities of micro-structuring 13 and attach in a mechanically resistant manner and hermetically sealed after cooling. The cover member 5 may be peripherally attached to the frame member 7 in a hermetically sealed manner, for example by laser welding or gluing. The receiving housing 9 can thus be made hermetically sealed in its entirety, against an environment that may possibly contain fluids or aggressive agents.
    [0009] In the receiving housing 9 different electronic components 15, 17 may be arranged, such as, for example, electrical resistors, diodes, transistors, integrated circuits, etc., as well as at least one electronic sensor element 19, and electrically interconnected or interconnected or with an environment, for example via conductive tracks of the printed circuit board element 3. In the case of the electronic module 1 shown in FIG. 1, the detector element 19 must detect , for example through the cover member 5, measurement variables to be measured outside the electronic module 1. For some measuring purposes and for some applications, the sensor element 19 may not be arranged optimally, or a field to be measured may for example not penetrate sufficiently inside the electronic module to the detector element r that is there.
    [0010] Figure 2 shows an electronic module 1 according to an embodiment of the present invention. Here, a cover member 5 has protrusions 21, 23 with which the receiving housing 9 is enlarged locally and in each of which a detector element 25, 27 is housed respectively. A printed circuit board element 3, 1 cover member 5 and a frame member 7 here hermetically sealed, the receiving housing 9, similarly to the example of Figure 1. However, in the embodiment shown in Figure 2 not only electronic components 15, 17 are provided on the printed circuit board element 3, but in addition there is provided another printed circuit board element 29 inside the receiving housing 9, in the immediate vicinity of the cover member 5, and on this other printed circuit board element are arranged, directly or via partial elements of the printed circuit board 35. flexibly, other electronic components 31, 33 as well as the detector elements 25, 27. The detector elements 25, 27 engage here at least partially in one of the projections 21, 23. The elements Detectors 25, 27 are here arranged and oriented within the respective protuberance 25, 27, so as to be able to detect approximately optimally, a measurement variable varying outside the electronic module 1.
    [0011] Such a measurement quantity may for example be a magnetic or electric field, which is produced by a sensor element 37, 39 moving relative to the electronic module 1, and which, due to the scanning of the zone of the respective detector elements respectively by the sensor element 37 in the area of the associated sensor element 25, 27 varies over time. The electronic module 1 can produce a gearbox control device with which, in common with the sensor elements 37, 39, it is possible to develop a set of sensor sensors 41 of a control box gear, so that it is for example possible to perform reliably and accurately, a position determination or determination of rotational speed of components inside a gearbox of a motor vehicle. The sensor elements 37, 39 can here be arranged for example on rotating components of a gearbox, so that it is possible to determine with the aid of the sensor elements 25, 27, information relating to current positions of gearbox components. In the embodiment shown in Figure 2, the cover member 5 is for example an injection molded plastic part. It can be connected or assembled hermetically sealed with the frame member 7, for example by welding, gluing, matting or otherwise. The additional printed circuit board member 29 may for example be clamped between the frame member 7 and the cover member 5 attached thereto, or may be mechanically bonded to one of these elements. In the embodiment shown, the additional printed circuit board element 29 is connected to the printed circuit board element 3 via a partial area 43 bent vertically, as well as electrically conductive via a chip 45 provided on the printed circuit board member 3. Furthermore, between the printed circuit board member 3 and the cover member 5, a support member 47 is provided. , for example to prevent vibration and / or bending of the lid member 5 due to pressure differences. FIG. 3 shows a partial zone of another embodiment of an electronic module 1 according to the invention. Detector elements 25, 27 are again arranged in protuberances 21, 23, which are formed as partial valleys in a cover member 5 for locally enlarging the receiving housing 9. The detector elements 25, 27 are here respectively arranged on printed circuit board partial elements 49, 51, which are mechanically and / or electrically connected to either the printed circuit board element 3, or for example to other components inside the 9 to 9, (not shown), via a flexible zone 53, 55. In order to be able to mechanically fix a sensor element 27 inside a protrusion 23, these two components can be mutually adapted as to their dimensions. , so that the sensor element 27 can be tightly inserted into the protrusion 23. Alternatively, within the protrusion 23, an element of Inwardly projecting projection 57 may be used for fixing the sensor element 27. The clamping element 57 may have, for example because of its geometrical configuration and / or of a material used, an elasticity. adapted to produce a clamping effect. In order to be able to better detect a variable variable outside the electronic module 1 and produced by a sensor element 37, 39, the cover element 5 may have, in the zone of an outgrowth 21, 23, locally in a partial area 59, 61 or also along the entire outgrowth 21, 23, a lesser thickness relative to directly adjacent areas. By way of example, the thickness in the partial area 59, 61 may be less than 80% or less than 50% of the thickness in areas directly adjacent to the cover element 5. In such a partial area 59 With reduced thickness of material, fields produced for example by a sensor element 37, 39 can penetrate more easily inside the electronic module 1, and be picked up by one of the detector elements 25, 27. 25
