Definitions
- the invention relates to a sound generator, in particular for parking assistance systems for vehicles, with a housing which has a base part and a cover part, the base part comprising a receiving space which can be covered by the cover part, for receiving a membrane, and a method for producing and assembling a sound generator.
- Such tone generators are used to facilitate the parking of vehicles.
- obstacles in the vicinity of the vehicle are detected by suitable sensors. If the vehicle approaches a detected obstacle beyond a limit distance, the driver of the vehicle is informed via visual or acoustic displays that the limit distance has been undershot.
- the parking aid systems are preferably designed in such a way that the display intensity increases when the vehicle falls below a first limit distance, when the vehicle approaches the detected obstacle further. This can be done, for example, by means of variable-size display elements and / or by changing a signal tone frequency.
- the optical and / or acoustic display elements are positioned in the vehicle such that there is a spatial relationship between the sensors surrounding the vehicle and the respective display elements.
- the display is made by an element which is arranged in the rear right area of the passenger compartment.
- a large number of display elements for example sound generators
- the previously known tone generators for parking assistance systems consist of a large number of individual parts which have to be joined together in a complex manner.
- a sound-generating element for example a membrane
- the housing has a separate cover, which can be separated from a lower housing part when external forces are applied, as a result of which the membrane can be unintentionally exposed.
- the object of the present invention is to provide a tone generator which is distinguished by a particularly simple and inexpensive producibility and by a high level of functional reliability.
- the object is achieved according to the invention in a tone generator of the type described at the outset in that the base part is formed in one piece with the cover part via a connecting section, the base part and the cover part being movable relative to one another and being jointable by means of jointing means.
- the one-piece housing design makes it possible to produce a tone generator by joining two components, that is, the housing and the membrane.
- the housing has the task of a sound generating element, such as a membrane to both position and protect against external influences.
- both the positioning and the protective function can be implemented simultaneously by positioning the membrane in the base part and covering the membrane by the cover part of the one-piece housing.
- the housing has a connecting section between the base part and the cover part, through which the base part and the Cover part are movable relative to each other.
- the connecting section is advantageously designed as a film hinge. This has the advantage that the housing with base part, cover part and film hinge can be molded as an injection molded part in one production process. Appropriate dimensioning of the film hinge ensures that, on the one hand, a sufficiently strong material cohesion is created between the base part and the cover part and, on the other hand, the connection section is sufficiently flexible to enable the base part and cover part to be joined without plastic deformation or destruction of the connection section. In such a joining process, the film hinge is brought from an undeformed position in which two sections of the film hinge lie in one plane to a deformed position in which the sections connected to the cover part and the base part lie one above the other.
- the joining means with which the base part and the cover part can be joined together are designed as locking means.
- Such latching means can be designed, for example, as snap connections and can be integrally formed in the housing of the tone generator in one manufacturing process.
- Such joint connections have the significant advantage that neither additional connecting elements nor special tools are required to produce a reliable joint.
- suitable elements can be formed without undercuts, which simplifies the construction of the injection molding tool.
- connection section and the jointing means are arranged on opposite sides of the base part. With this arrangement, base part and cover part are joined together in the state held as far apart from each other as possible.
- the connecting section as part of the housing holds base part and cover part together on a first side of the housing; the jointing means, in particular the latching means, hold the base part and cover part together on a second, opposite side of the housing. Opening forces acting from the outside can be absorbed particularly well by the proposed arrangement from the housing without the cover part being separated from the base part.
- the membrane which is inserted into the housing of the tone generator, is formed in one piece with electrical contact means.
- the electrical contact means are designed, for example, as metal tongues which are soldered to the membrane or are otherwise connected to the membrane.
- the membrane can be joined to the housing by the electrical contact means without subsequent electrical contact points having to be created by soldering processes, as is known from the prior art.
- the receiving space in the base part of the housing advantageously has a membrane insertion area and a contact means insertion area.
- an area can be provided in which the membrane can be inserted so as to be able to float, and on the other hand an area can be created in which the electrical contact means are arranged in a fixed position and in a defined position in order to form part of an electrical plug connection for an externally feedable plug.
- the membrane laying area is delimited by a bottom surface and a wall surface arranged circumferentially and perpendicular to the bottom surface and has an opening for inserting the membrane parallel to the bottom surface.
- the contour of the receiving space corresponds to the contour of the membrane or the contour of the membrane with the electrical contact means, so that the membrane can be inserted in the vertical direction parallel to the bottom surface of the membrane insertion area.
- the proposed arrangement ensures that on the one hand the membrane in the housing is fixed in a plane parallel to the membrane and on the other hand the membrane can be inserted into the base part of the housing by a particularly simple joining process.
- the joining process in a direction perpendicular to the bottom surface of the membrane insertion area can be automated in a particularly simple manner and can be described and implemented using a single joining direction.
- the contact means insertion area is advantageously delimited by a bottom surface and two side walls arranged on the bottom surface, which preferably merge into the wall surface of the membrane insertion area.
- the proposed arrangement ensures that the membrane and the electrical contact means are seamless from
- Housing components are surrounded and thus protected from external influences. Furthermore, only a particularly small space is required.
- the joining means and in particular the latching means are advantageously arranged on the two side walls, which delimit the contact means insertion area.
- This arrangement ensures that the base part and cover part of the housing can be joined without additional joint elements having to be provided. It is also particularly simple to design the latching means in this area without undercuts, which simplifies the construction of an injection molding tool to the extent that no lateral slide elements have to be provided in the tool.
- the contact means insertion area also advantageously has a web which is arranged at a distance from the bottom surface between two areas of the side walls. The web, the two side walls, and the bottom surface form an all-round opening for an externally feedable plug, which is inserted through the opening and received by the contact means insertion area. The web can absorb any forces acting on the connector and guide them into the housing without the cover part being able to be pried open from the base part. Furthermore, a precisely defined and interference-resistant routing of the external connector is guaranteed.
- means for defining the installation position of the membrane are provided in the base part of the housing. These means ensure that the membrane can only be placed in the membrane insertion area in a single installation position. This ensures that the electrical connection of the membrane is carried out correctly by connecting the electrical contact means to an externally supplied plug.
- the means for defining the installation position can be formed, for example, in a transition area which is formed between the wall surface delimiting the membrane insertion area and the contact means insertion area.
- the transition area is delimited by two opposite wall surfaces, the distance between which increases in a direction parallel to the bottom surface of the membrane insertion region from the bottom surface to the opening, lateral guide surfaces being provided on the membrane and / or on the electrical contact means, which guide surfaces are located opposite the opposite Wall surfaces are complementary.
- the membrane and / or the electrical contact means can thus be guided to the wall surfaces delimiting the transition area, with complete insertion the membrane in the membrane insertion area is only possible if the membrane is in the correct installation position.
- the cover part of the housing of the sound generator advantageously has at least one sound outlet opening and at least one fastening means for fastening the sound generator on an external carrier.
- the fastening means can be formed integrally with the cover part and can thus be produced together with the housing in one manufacturing process, for example by injection molding.
- the arrangement of the fastening means on the cover part of the tone generator ensures that after the cover part and base part have been joined and the tone generator has been fastened to an external carrier, the base part is caught by the cover part. A blasting off or prying open of the cover part from the base part is therefore only possible if the fastening means are previously detached from the external carrier.
- the cover part encompasses the base part and its membrane insertion area and contact means insertion area, which are thus protected from external influences.
- the fastening means can be adapted to the respective mounting location of the sound generator as tabs, as locking or as clamping means.
- additional connecting elements such as Screws are passed through and turned into an external carrier material, for example in sheet steel.
- the external carrier is also made of plastic material, it may be advantageous for the tone generator to be joined to the external carrier by means of locking or clamping means.
- the external carrier and the tone generator can carry suitable locking or clamping means.
- the surfaces of the fastening means facing the external carrier can be arranged parallel to the plane of the base surface of the base part or slightly to the base surface of the Basically be spaced. This ensures that the base part with its bottom surface comes to rest on a support surface of the external carrier and is therefore not movable relative to the external carrier.
- the fixing of the base part to the external support can be supported in that the surfaces of the fastening means facing the external support are slightly spaced apart from the base surface of the base part.
- the base part advantageously has at least one spacer, by means of which the membrane arranged in the membrane insertion area is spaced apart from the bottom surface of the membrane insertion area. This ensures that the membrane can vibrate freely within the membrane insertion area and thus can also set the air surrounding the membrane in vibration.
- the cover part advantageously has at least one fixing means which fixes the membrane between the fixing means and the bottom surface of the membrane insertion area or the at least one spacer when the cover part and base part are joined together. The proposed arrangement prevents the membrane from being movable relative to the housing and, for example, causing annoying rattling noises. In addition, the mechanical stress caused by shocks and vibrations is significantly reduced.
- the spacers and / or the fixing means can be designed as projections or lugs in the base part or in the cover part of the housing and can be produced together with the housing without an undercut in one manufacturing process.
- the housing is advantageously made of plastic and is manufactured by injection molding.
- the casting tool provided for this purpose advantageously consists of a basic shape and interchangeable inserts, the shape and / or at least one of the dimensions of the at least one fastening means and / or the contact means insertion area being alternatively formed by the interchangeable areas in the casting tool.
- the interfaces of the sound generator to external elements can be adapted to the particular application conditions.
- small series for specific collection traps can be represented more cheaply.
- a replacement insert for a specific fastening means or a replacement insert for a newly designed contact means insertion area has to be designed and manufactured without the basic tool having to be changed in its structure.
- the invention also relates to a method for mounting a tone generator, the tone generator being produced by the following method steps:
- a one-piece housing with base part and cover part is provided, then a membrane with electrical contact means is inserted in the receiving space of the base part of the housing and finally the cover part and the base part are joined together.
- the method steps shown can be easily automated, especially if the membrane vertical direction is inserted parallel to the floor area in the recording room.
- FIG. 1 shows a perspective view of a housing of a tone generator according to the invention
- Fig. 3 a tone generator according to the invention in the fully assembled state.
- Fig. 1 shows a housing 2 of a tone generator according to the invention, which is made of plastic and has a base part 4 and a cover part 6.
- the base part 4 has a membrane placement area 8 and a contact means placement area 10.
- the membrane laying area 8 has a bottom surface 12, a wall surface 14 arranged circumferentially and perpendicular to the bottom surface 12, and an opening 16 for inserting a membrane 38 shown in FIG. 2.
- a transition area 18 to the contact means insertion area 10 is formed in the wall surface 14.
- the contact means insertion area 10 is formed from a bottom surface 20, two rare walls 22, 22 and a web 24.
- the web 24 is formed at a distance from the bottom surface 20 between the rare walls 22, 22 '.
- the Contact means insertion area 10 is designed such that electrical contact means 40 shown in FIG. 2, which are connected to the membrane 38 to be inserted into the membrane insertion area 8, can be inserted and can establish an electrical connection with the externally feedable plug.
- Latching means 26 are formed on the rare walls 22, 22 'of the contact means insertion area 10.
- the locking means 26 of the base part 4 can cooperate with locking means 26 'of the cover part 6.
- the projections of the latching means 26 are in the engaged position with the projections of the latching means 26 '.
- the locking means 26 ' are designed such that they can be produced without an undercut.
- Corresponding openings 27 are provided in the cover part 6 for this purpose.
- the cover part 6 is connected to the base part 4 via a film hinge 28, so that when the base part 4 and cover part 6 are joined by pivoting about a pivot axis 29, a connection is made on the one hand via the film hinge 28 and on the other hand via the latching means 26, 26 '.
- the cover part 6 has fastening means 30 with which the cover part 6 with the base part 4 trapped therein can be fastened to an external carrier (not shown).
- the fastening means 30 are designed as tabs for receiving fastening screws.
- the base part 4 and the cover part 6 have further elements with which the structural position of a membrane is determined.
- the functional surfaces 32, 32 ' which delimit the wall surface 14 and form the transition region 18 are provided, the functional surface 32 extending obliquely to a direction perpendicular to the bottom surface 12 of the membrane insertion region 8.
- the functional surface 32 acts with a complementarily shaped surface 42 shown in FIG membrane 38 to be inserted together.
- Spacers 34 are also provided in the base part 4, which space the membrane 38 to be inserted from the bottom surface 12.
- Fixing means 36 are provided in the cover part 6, with which a membrane 38 placed on the spacers 34 is held when the cover part 6 and the base part 4 are joined together.

- the supply of the electrical contact means 40 to the membrane 38 is designed such that a functional surface 42 is provided which can interact with the functional surface 32 in the base part 4 of the housing 2.
- the functional surface 42 extends obliquely to a direction perpendicular to the membrane 38 and is complementary to the functional surface 32. Due to the interaction of the functional surfaces 32 and 34, the membrane 38 can only be inserted in one assembly position in the membrane insertion area 8 formed in the base part 4, as a result of which the electrical contact means 40 m connected to the membrane 38 and inserted in the contact agent insertion area 10 have a confusion-protected, defined position relative to Housing 2 of the sound generator are brought, whereby an electrical connection to an externally feedable connector is made correctly.
- the membrane 38 shown in FIG. 2 with the electrical contact means 40 can be inserted into the base part 4, so that the membrane 38 is inserted in the membrane insertion area 8 and the electrical contact means 40 in the contact means insertion area 10.

- the fastening means 30 ' are designed as latching means which have openings 31 into which latching means, not shown, which are connected to an external carrier or are formed on the carrier, can engage. Because the fastening means 30 ′ are formed on the cover part 6, the base part 4 is caught by the cover part 6 when the sound generator is mounted on an external carrier. It is only possible to detach the cover part 6 from the base part 4 if the tone generator is previously removed from the external carrier by loosening the fastening means 30 '.
- the electrical connection of the membrane 38 is carried out by introducing a plug, not shown, in the direction of arrow 44.
