Description

Technical Field

[0001] The invention relates to a functional unit for a vehicle, a vehicle and a method for producing a functional unit. Background Art

[0002] A sensor unit for a vehicle may have a housing for protecting components, such as electronic components. For data communication with the electronic components in the housing and / or for supplying power to the electronic components in the housing, the sensor unit may have an interface component, such as a plug connector. Fluids, such as water, can disadvantageously enter the electronic components through the sealing surface formed by the outer side of the plug connector and the housing, thereby compromising the functionality of the sensor unit.

[0003] In addition, in the automotive field, attention is paid to how to keep the structural space of components, such as sensor units, small while maintaining the sealing of, for example, plug connectors and housings. This can also disadvantageously lead to a reduction in the connection strength of the plug connector and the housing.

[0004] Furthermore, in the automotive sector, there is an interest in being able to produce components, such as sensor units, particularly cost-effectively. Summary of the Invention

[0005] The object of the present invention is to at least partially eliminate the aforementioned disadvantages. In particular, the object of the present invention is to provide a functional unit for a vehicle and / or a vehicle having a functional unit according to the present invention, wherein the functional unit has particularly advantageous fluid-tightness, in particular at the sealing surface formed by the outer side of the interface component of the functional unit and the housing of the functional unit, and / or the functional unit is particularly simple to manufacture and / or particularly saves installation space and / or is particularly cost-effective. Furthermore, in particular, the object of the present invention is to provide a method by which the functional unit according to the present invention can be manufactured in a particularly simple and / or cost-effective manner.

[0006] The above-mentioned object is achieved by a functional unit having the features of claim 1, a vehicle having the features of claim 12, and a method having the features of claim 13. Further features and details of the invention are derived from the dependent claims, the description, and the drawings. Features and details described in conjunction with the functional unit according to the invention naturally also apply in conjunction with the vehicle and / or method according to the invention, and vice versa, so that reference is always made to each other or can be made to each other with respect to the disclosure of the individual inventive aspects.

[0007] According to a first aspect, the present invention provides a functional unit for a vehicle. The functional unit comprises a housing for protecting at least one electronic component, the housing having at least one interface section for accommodating an interface component. Furthermore, the functional unit comprises the at least one electronic component for the function of the functional unit, the at least one electronic component being arranged in the housing. Furthermore, the functional unit comprises the at least one interface component having at least one first component end and at least one second component end, at least one groove being formed in the first component end along at least the longitudinal axis of the first component end and extending at least partially radially around the longitudinal axis of the first component end, and the second component end of the interface component protruding beyond the housing, in particular beyond the housing wall, into the surroundings of the functional unit, particularly in the region of the interface section of the housing. Furthermore, in the functional unit, the first component end of the at least one interface component having the at least one groove is arranged, in particular sealingly arranged, on at least one edge of the interface section of the housing that is configured correspondingly to the at least one groove, so as to form at least a positively locking connection, in particular an at least positively locking, sealed connection.

[0008] The functional unit may be a sensor unit and / or an electronics unit and / or a control unit for a vehicle. For example, the sensor unit may be a motor position sensor for detecting the rotational speed and / or position of a motor shaft of a motor, particularly an electric motor, of a vehicle (functioning as a motor position sensor). The motor position sensor may include a printed circuit board having at least one transmitting coil, at least one receiving coil, and evaluation electronics, and a rotor that can be attached to the motor shaft. In particular, the printed circuit board having the at least one transmitting coil, the at least one receiving coil, and the evaluation electronics is protected by a housing of the functional unit, preferably an injection-molded housing, and the printed circuit board having the at least one transmitting coil, the at least one receiving coil, and the evaluation electronics is injection-molded overmolded.

[0009] The housing can be an injection-molded housing, in particular, the housing can be injection-molded or injection-molded such that at least the at least one electronic component, for example, an electronic computing unit (e.g., a microcontroller), is at least partially injection-molded or injection-molded. The expression "injection-molded" or "is injection-molded" should mean that the housing is directly applied to the at least one electronic component by means of an injection molding process. As a result, the at least one electronic component can be particularly advantageously protected by the housing and / or the functional unit can be designed to save particularly large structural space. For example, the housing can be a thermosetting (injection-molded) housing, in particular, an injection-molded thermosetting housing that is dimensionally stable or substantially dimensionally stable. Advantageously, the thermosetting housing can also be particularly chemically and thermally stable and have a particularly high strength and / or hardness.

[0010] The at least one electronic component can be, for example, a computing unit (such as a microcontroller) and / or an electrically conductive conductor track and / or a printed circuit board. A plurality or a plurality of electronic components can also be arranged in the housing.

[0011] Since the interface component of the functional unit has a first component end arranged on the interface section of the functional unit and a second component end protruding beyond the housing, the interface component can be arranged, in particular fixed, to the interface section (by means of the first component end), or the second component end can perform at least one further function. For example, the second component end can serve as a fixing section for fixing the functional unit to a matching fixing section of the vehicle and / or for arranging a plug (e.g., for data communication with the at least one electronic component in the housing and / or for supplying power to the at least one electronic component in the housing).

[0012] In particular, the first component end of the at least one interface component and the interface section of the housing are arranged close to each other so that they (at least in sections) contact each other. Furthermore, the first component end of the at least one interface component, preferably the outer side of the first component end, and the interface section of the housing that contacts the first component end, in particular the mating surface of the at least one interface section that contacts the outer side of the first component end, can form a seal having a sealing surface. The at least one groove extending at least partially radially around the longitudinal axis of the first component end in the first component end can advantageously make the sealing surface formed by the first component end of the at least one interface component and the interface section of the housing that contacts the first component end particularly large, at least in sections. Furthermore, this makes the connection between the housing and the at least one interface component particularly stable. Furthermore, the sealing length (of the seal) can be particularly long, at least in sections, and in particular, the overlap between the first component end of the interface component and the interface section of the housing can be kept particularly small or short. As a result, on the one hand, the path of the fluid from the surroundings of the functional unit to the risk location (such as the at least one electronic component) can be particularly long, at least in sections, and on the other hand, the functional unit can be designed to save particularly large amounts of structural space. Furthermore, the at least one groove can create detours or curves that make it particularly difficult for fluid (such as water) to pass from the surroundings of the functional unit to the at least one electronic component. In other words, the at least one groove on the first component end of the at least one interface component and the at least one edge of the interface section of the housing, which is designed to correspond to the at least one groove, can form a labyrinth seal.

[0013] In particular, at least the first component end of the at least one interface component having the at least one groove is arranged on the at least one edge of the interface section of the housing configured to correspond to the at least one groove, or on the interface section of the housing having the at least one edge configured to correspond to the at least one groove, such that the at least positive connection is gap-free or substantially gap-free, in particular to achieve an at least positively sealed connection. Consequently, the at least one interface section of the housing and the at least one interface component or the first component end of the interface component can serve as a seal, and the flow of fluid (e.g., water) from the surroundings of the functional unit to the at least one electronic component can be particularly advantageously kept low. For example, the at least one interface section of the housing can be injection-molded onto the first component end of the at least one interface component (having the at least one groove) to form, in particular, the at least one edge configured to correspond to the groove. By injection molding the at least one interface section, it is particularly advantageous to ensure that the at least positive connection is gap-free or substantially gap-free, since, for example, thermosetting plastic materials have a particularly low viscosity before the crosslinking reaction, so that the at least one recess on the first part end of the at least one interface part can be particularly advantageously filled during the injection molding process. This makes it possible to provide the functional unit with particularly advantageous fluid-tightness.

[0014] Advantageously, in the functional unit according to the present invention, a plurality of grooves are formed in the first component end of the at least one interface component along the longitudinal axis of at least the first component end, each extending at least partially radially around the longitudinal axis of the first component end. In particular, the plurality of grooves are formed one after the other along the longitudinal axis of at least the first component end, and the first component end of the at least one interface component having the plurality of grooves is each disposed on at least one edge of the interface section of the housing configured to correspond to a corresponding groove of the plurality of grooves, so as to form at least a positive connection, in particular a positively sealing connection. As a result, the sealing surface formed by the first component end of the at least one interface component and the interface section of the housing in contact with the first component end can be particularly large, at least in sections, and the sealing length can be particularly long, at least in sections. Furthermore, the plurality of grooves can create a plurality of deflections or curves, making it particularly difficult for fluids (such as water) to pass from the environment of the functional unit to the at least one electronic component. Alternatively or in addition to the embodiment in which the plurality of grooves are formed one after the other along the longitudinal axis of at least the first component end, it is also conceivable that the plurality of grooves are formed nested within one another. In other words, a groove can be formed within a groove and can form a T-shape or an approximately T-shape. Thus, the sealing length can be particularly long, while at the same time, the overlap between the first component end of the interface component and the interface section of the housing can be kept particularly small or short. Furthermore, it can be advantageous if, in the functional unit according to the present invention, the multiple grooves (formed in the first component end of the at least one interface component) have different dimensions, in particular, different depths and / or different widths and / or different lengths. Thus, for example, during the injection molding process for molding the at least one interface section of the housing to form the corresponding edges, it can be particularly advantageous to ensure that each of the multiple grooves is completely filled with injection molding material. Alternatively, however, it is also conceivable for the multiple grooves to have the same or substantially the same dimensions. Thus, the first component end having multiple grooves of the interface component can be manufactured particularly simply, for example, using a (separate) injection molding process. The dimensions of the grooves may be understood to include length, width, and depth. In particular, the length of the groove is the extension of the groove in the circumferential direction around the longitudinal axis of the first component end of the at least one interface component, and / or the depth of the groove is the extension of the groove in the radial direction relative to the longitudinal axis of the first component end of the at least one interface component, and / or the width of the groove is the extension of the groove in the direction of the longitudinal axis of the first component end of the at least one interface component.

[0015] The features and / or details and / or advantages mentioned with respect to the at least one groove formed in the first component end of the at least one interface component can also be transferred to the other groove formed in the first component end of the at least one interface component, and vice versa. In addition, the features and / or details and / or advantages mentioned with respect to the at least one edge formed corresponding to the at least one groove can also be transferred to the other (corresponding) edge of the interface section of the housing, and vice versa.

[0016] Advantageously, in the functional unit according to the present invention, the at least one groove in the first component end of the at least one interface component has a width of between 0.5 mm and 4.0 mm, preferably between 1.0 mm and 2.0 mm, and / or the at least one groove has a depth of between 0.5 mm and 4.0 mm, preferably between 1.0 mm and 2.0 mm. Consequently, the at least one groove can have particularly small dimensions, in particular a particularly small width, and the overlap between the first component end of the interface component and the interface section of the housing can be kept particularly small or short. Consequently, the functional unit can also be designed to save particularly large amounts of space.

[0017] Advantageously, in the functional unit according to the present invention, the at least one recess in the first component end of the at least one interface component is formed on the outer side of the first component end of the interface component. Thus, for example, at least the first component end of the at least one interface component can be manufactured particularly easily, in particular by means of an injection molding process, from a plastic material, in particular a thermoplastic plastic material. The outer side of the first component end may be understood to mean, in particular, the outer circumference of the first component end.

[0018] It can be advantageous if, in the functional unit according to the present invention, the at least one groove in the first component end of the at least one interface component is designed to completely circumscribe radially around the longitudinal axis of the first component end. This allows the sealing surface formed by the first component end of the at least one interface component and the interface section of the housing, and thus the fluid-tightness of the housing, to be particularly large. Furthermore, this allows the (positive-locking) connection between at least the housing and the at least one interface component to be particularly stable. Furthermore, the (corresponding) sealing length (of the seal) radially around the longitudinal axis of the first component end can be particularly long. This allows the fluid-tightness of the functional unit, in particular the housing of the functional unit, to be particularly advantageous.

[0019] It can be advantageous if, in the functional unit according to the invention, the first component end of the interface component and the interface section of the housing overlap along the longitudinal axis of at least the first component end of the at least one interface component by less than 10 mm, in particular less than 6 mm, preferably less than 4 mm. Consequently, the overlap of the first component end of the interface component and the interface section of the housing can be kept particularly small or short, and the functional unit can be designed to save particularly large installation space, since, for example, the overall length of the interface component can be kept particularly short.

[0020] It can be advantageous if, in the functional unit according to the invention, the first component end of the at least one interface component is at least partially injection-molded from a (first) plastic material, in particular a thermoplastic plastic material and / or a thermosetting plastic material, so that the at least one groove is formed in the injection-molded portion of the first component end of the interface component. Consequently, the at least one groove in the first component end of the interface component can be manufactured particularly easily. Advantageously, the thermoplastic first component end of the at least one interface component can be manufactured particularly easily in large quantities and with high precision. Thus, particularly "thin" grooves can also be manufactured, for example with a width of between 0.5 mm and 4.0 mm, preferably between 1.0 mm and 2.0 mm, and / or a depth of between 0.5 mm and 4.0 mm, preferably between 1.0 mm and 2.0 mm.

[0021] Advantageously, in the functional unit according to the present invention, the at least one interface section of the housing is injected, in particular overmolded, onto the first component end of the at least one interface component having the at least one recess by means of an injection molding process, thereby forming at least a positive connection. This provides the housing of the functional unit with particularly advantageous fluid tightness. For example, a thermosetting plastic material can be introduced during the injection molding process to inject the at least one interface section of the housing having the at least one edge configured corresponding to the at least one recess, thereby forming at least a positive connection, in particular a non-positive and positive connection, preferably a non-positive, positive, and materially bonded connection. The thermosetting plastic material can be, for example, an epoxy resin and / or a wet polyester.

[0022] Advantageously, in the functional unit according to the present invention, the functional unit is a sensor unit and / or an electronics unit and / or a control unit, and in particular, the at least one interface component is a plug connector. For example, the sensor unit may be a motor position sensor for detecting the number of revolutions and / or position of a motor shaft of a motor, in particular an electric motor, of a vehicle (functioning as a motor position sensor). The plug connector may have at least one electrical contact element or multiple electrical contact elements for data communication with the at least one electronic component in the housing and / or for supplying power to the at least one electronic component in the housing. A plug connector may also be understood as a plug socket.

[0023] It can be advantageous for at least the interface section of the housing in the functional unit according to the present invention to be formed from a (second) plastic material, in particular a thermosetting plastic material and / or a thermoplastic plastic material, in particular by injection molding. Advantageously, the thermosetting interface section of the housing can be particularly chemically and thermally stable and have particularly high strength and / or hardness. Advantageously, thermosetting plastic materials, such as epoxy resins, can also have a particularly low viscosity prior to the crosslinking reaction, making it particularly easy and reliable to inject or overmold the at least one electronic component and / or at least the first component end of the at least one interface component, in particular the at least one recess in the first component end. Preferably, in the functional unit according to the present invention, at least 50%, preferably at least 80%, and more preferably at least 90% of the housing with the interface section is manufactured from a plastic material, in particular a thermosetting plastic material and / or a thermoplastic plastic material, by means of an injection molding process.

[0024] Furthermore, it is conceivable that the first component end of the at least one interface component is formed at least partially from a first plastic material and the interface section of the housing is formed from a second plastic material; in particular, the first plastic material and the second plastic material can be identical or different.

[0025] According to a second aspect, the invention relates to a vehicle having at least one functional unit according to one of the preceding claims.

[0026] In particular, the vehicle is a motor vehicle. The motor vehicle may be a car, a truck, or a motorcycle. In particular, the motor vehicle may have at least one electric motor for driving the motor vehicle. For example, the at least one functional unit of the vehicle may be a motor position sensor for detecting the rotational speed and / or position of a motor shaft of the at least one electric motor of the motor vehicle.

[0027] The vehicle according to the second aspect of the invention thus has the same advantages as have been described with respect to the functional units according to the first aspect of the invention.

[0028] According to a third aspect, the present invention provides a method for producing a functional unit, wherein the functional unit is constructed according to the present invention, in particular according to the first aspect of the present invention. As a step, the method comprises placing at least one electronic component in an injection mold. Furthermore, as a step, the method comprises placing at least one interface component in the injection mold, wherein at least one groove extending at least partially radially around the longitudinal axis of at least one first component end of the interface component is formed in the first component end along the longitudinal axis of the first component end. Furthermore, as a step, the method comprises introducing an injection molding material, in particular a thermosetting injection molding material, into the injection mold in order to form a housing together with at least one edge of the interface section of the housing, which is constructed corresponding to the at least one groove, for at least a form-fitting connection, in particular for a force-fitting and form-fitting connection, preferably for a force-fitting, form-fitting and material-fitting connection, in particular by forming a seal by means of the connection.

[0029] The injection mold can have at least one first injection mold part and one second injection mold part. The at least one electronic component can be arranged, in particular, inserted, into the first injection mold part. To produce a motor position sensor (as a functional unit), for example, a printed circuit board having at least one transmitting coil, at least one receiving coil, and evaluation electronics can be placed into the first injection mold part. Furthermore, the at least one interface component, such as a plug connector, can be arranged, in particular, inserted, into the first injection mold part or the second injection mold part. At least the first and second injection mold parts can then be joined to form a fillable cavity. Subsequently, an injection molding material, in particular a thermosetting injection molding material, can be introduced into the formed fillable cavity of the injection mold to form the housing of the functional unit, including at least one edge of its interface section configured to correspond to the at least one recess (formed in the first component end of the interface component), for at least a positive-locking connection.

[0030] The method according to the third aspect of the invention thus has the same advantages as have already been described with respect to the functional unit according to the first aspect of the invention or the vehicle according to the second aspect of the invention.

[0031] As far as technically appropriate, the method steps described above and below can be carried out individually, jointly, once, several times, in parallel in time and / or successively in any order.

[0032] Further measures for improving the present invention are apparent from the following description of some exemplary embodiments of the present invention, which are schematically illustrated in the accompanying drawings. All features and / or advantages arising from the claims, the description, or the drawings (including structural details, spatial arrangements, and method steps) may be essential to the present invention both individually and in various combinations.
