Definitions

  • the present invention relates to a handle part for a motor vehicle door comprising a base body having at least one cavity into which opens at least one electrical conductor, and at least one electronic unit which can be arranged in the at least one cavity and connectable to the at least one electrical conductor.
  • Such gripping parts are particularly suitable for accommodating processors, sensors, drives, antennas and similar electrical components and thus for example also providing the possibility to position touch sensors outside the motor vehicle.
  • non-contact sensors for realizing the so-called "keyless entry" can be used.
  • a door handle is known in which, for example, the sensor electronics and the antenna are inserted in a hollow of the handle and cast there. It is proposed in particular that the electronic components are designed as a module so that they withstand the pressure and temperature stresses occurring during encapsulation with plastic.
  • the electronic components of the sensor system and optionally the probe are mounted on a printed circuit board and are connected, for example by a soldering process, to the conductor tracks of the printed circuit board.
  • a ribbon cable can form the electrical connection to an electronics arranged outside the handle.
  • the electronic components together with the printed circuit board can then be inserted, possibly still the antenna is attached. Subsequently, a soft plastic material added that this unit of sensor electronics, probe and antenna sheathed.
  • a door handle is to be specified, which can also be flexibly manufactured and used in terms of automated production in mass production.
  • the ease of maintenance and / or the ease of assembly should be improved.
  • a secure and permanent Konekttechnik the internal electronics unit is to ensure just under extreme driving conditions of the motor vehicle.
  • the motor vehicle door handle comprises a base body having at least one cavity into which at least one electrical conductor terminates, and at least one electronics unit connectable in the at least one cavity and connectable to the at least one electrical conductor, wherein cooperating means for positioning the Electronic unit are provided with respect to the at least one conductor in the cavity and on the electronic unit.
  • such a grip part can be produced from a multiplicity of different parts, wherein the at least one cavity is surrounded or at least delimited by a so-called base body. Regularly, such a base body only have a cavity, but this is not absolutely necessary. Also, the number of electrical conductors that open into this cavity need not be limited to an electrical conductor, but may be provided for controlling or operating the at least one electronic unit and a plurality of electrical conductors. Normally, such a grip part will be executed only with a single electronic unit, however, it may, for example due to the shape of the base body or the handle part u. U. be required to divide the electronics unit into two modules and to arrange separately from each other in a common or each in a cavity.
  • means be provided for positioning the electronic unit with respect to the at least one conductor, wherein these means are formed both with the cavity and with the electronic unit and these means therefore cooperate for positioning.
  • the means in the cavity and on the electronic unit correspond to each other.
  • on the surfaces in the region of the cavity or created in the electronic unit outer geometries that can be brought to bear against each other, so that, for example, forms a kind of positive connection between the cavity and the electronic unit.
  • the cooperating positioning means comprise a plug-in connection formed in the cavity. Consequently, in particular a negative form of a plug is formed with the cavity, while a part of the electronic unit forms a positive shape of a plug.
  • the cooperating means for positioning comprise a cantilevered mounting for the electronics unit. This means in particular that at least during assembly or during a subsequent processing step, a fixation or alignment of the electronics unit in the cavity is accomplished alone on these cooperating means in the manner of a cantilevered bracket. Consequently, these holding means, in particular the corresponding plug connections, ensure that other components of the electronic unit extend freely into the cavity without further contact with the base body.
  • a gripping member is also considered advantageous, in which the cooperating means for positioning form a repeatable detachable contact between the at least one electrical conductor and the electronics unit.
  • the cooperating means for positioning are designed to include a plug-in connection as a cantilevered bracket that removably removes electrical contact to the conductor.
  • the cooperating means for positioning also comprise means for sealing the electrical conductor with respect to the cavity.
  • sealing means are provided which optionally even subdivide the cavity, namely into a contact region and a receiving region for the electronic unit.
  • the contact area refers to the part of the cavity from which the electrical conductors protrude or are connected to a corresponding plug connection.
  • the seal has the particular task of protecting this contact area from moisture or even from the plastic compound, which is optionally supplied later in the encapsulation of the electronics unit.
  • the electronic unit may have at least one base for contacting the grip part and at least one component carrier for at least one electronic component.
  • the base is shaped in particular in the manner of a positive plug part, so in particular has receptacles for an electrical conductor.
  • the component carrier is designed as a rigid plate-like component on which the electronic components are fastened and optionally electrically conductively connected to one another.
  • Electronic components may in particular be capacitors, resistors, sensors, antennas, Be button and the like.
  • the base is made relatively large, so that the largest possible contact surface is ensured with the base body.
  • the base has a cross-sectional area which makes up at least one third of the cross-sectional area of the component carrier, in particular even at least half as large as the component carrier.
  • an electronic unit is positioned, wherein a plastic mass fills the cavity otherwise.
  • This particularly relates to the region of the cavity, which extends from the sealing means to the opening of the cavity relative to the environment.
  • the at least one cavity can be closed by means of a flap.
  • the flap may be integrally connected to the base body, but this may also be a separately applicable component.
  • the flap is used, for example, to protect the electronics unit and / or the overmolded plastic compound. This flap can be securely fastened to the base body with a clip connection and / or with additional connecting means.
  • This door handle finds particular application in motor vehicles.
  • Fig. 1 shows a partial perspective view of a handle part 1, which is formed with a base body 3 made of plastic.
  • a cavity 4 is formed, as can be seen from the partial section.
  • an electrical conductor 5 which connects the cavity 4 with the terminal 15 to a motor vehicle door.
  • the terminal 15 (or plug) on the mounting portion 16 (or the illustrated bracket 19) is arranged.
  • the electrical conductor 5 is guided to the connection 15, in particular if the connection 15 is assigned to the fastening region 16.
  • the cavity 4 is designed so that means for positioning the electronic unit 6, here in the manner of a holder 8, are formed.
  • the electronics unit 6 extends into the cavity 4, but does not protrude beyond this.
  • Such a grip part 1 can be fastened with the fastening areas 16 indicated here, for example, to a motor vehicle door (not shown).
  • the electronics unit 6 has a substantially two-part construction and, in addition to a base 9, comprises a plate-like component carrier 10 on which a plurality of electronic components 11 (in particular on both sides) are provided or fastened.
  • a sensor surface 18 may be provided, which detects, for example, a touching contact on the handle part 1.
  • the relatively large base 9 is designed in the manner of a positive plug, wherein outside in the circumferential direction of the base 9, a sealing lip or a plurality of sealing lips 14 are provided, which are in contact with the boundary surface of the cavity 4 can be brought.
  • a subdivision of the cavity 4 in a contact region and a position range for the electronic unit can be effected.
  • at least one guide aid 17 is formed perpendicularly to these sealing lips 14 and interacts, for example, with correspondingly shaped wall regions of the cavity 4 or of the base body 3 when the electronics unit 6 is pushed into the cavity 4.
  • FIG. 3 and 4 now show a further embodiment of the handle part 1 for a motor vehicle door 2.
  • the Fig. 3 illustrates essentially the assembly process in which the electronic unit 6 is inserted into the cavity 4 of the base body 3, for example, the base. 9 the electronic unit 6 is securely positioned on the ends of the electrical conductors 5. 4, this joined state is shown.
  • the cavity 4 was provided with a suitable plastic compound 12 filled before the flap 13 ultimately covers the access to the cavity 4.
  • the terminal 15 (or plug) on the attachment portion 16 (or the bracket 19 shown) may be arranged, wherein the electrical conductor 5 is preferably guided to the terminal 15.
  • the invention finds particular use in motor vehicles, so that motor vehicles comprising at least one of the handle parts proposed here are covered by the invention.
