Definitions
- the invention relates to an electric motor, in particular a small electric motor, with a mounting adapter.
- Rear wiper motors are often attached to rear doors or tailgates.
- the attachment is usually such that the engine is located inside the vehicle. At such an attachment functional requirements are made.
- the attachment must guarantee a sufficiently accurate positioning of the rear wiper motor to allow an effective and reproducible operation of the wiper system. The accuracy of the positioning should depend as little as possible on typical operating loads. Therefore, the attachment is sufficiently stable to run to install the rear wiper against rotation and shock resistant.
- the described technical problems can generally be transferred to systems in which small electric motors have to be connected to differently shaped flat components, the connection having to absorb the torques applied by the motor.
- the object of the invention is to provide a way to specify a mounting option that allows fast and safe installation of an electric motor in particular as a wiper drive, the attachment has to be made against rotation, shock and noise decoupled.
- the invention is based on connecting an electric motor to a fastening adapter, wherein the connection region between the electric motor and fastening adapter ter can be configured independently of the later installation of the complete assembly.
- This allows a uniform execution of the electric motors, since an adaptation to requirements of the installation space is carried out exclusively by varying the mounting adapter.
- This variation of the mounting adapter is made outside the connection area between the electric motor and the mounting adapter.
- the connection between the electric motor and the mounting adapter is noise-decoupled by mounting mounting-friendly steaming elements made of rubber or similar materials on both sides of the mounting adapter, which prevent metallic contact between the mounting adapter and the electric motor.
- the invention is thus realized by an electric motor with a fastening adapter, wherein the fastening adapter comprises a central flat area which is embedded between two flat damping elements, wherein through the damping elements and the central region of the fastening adapter lead a plurality of openings through which fastening means, which at least partially bring about an elastic compression of the damping elements by pressing the arrangement of the flat damping elements and the fastening adapter against a flat region of a support structure firmly connected to the electric motor.
- a change of the mounting adapter is easily possible if the fastening means, which at least partially cause e- elastic compression of the damping elements by pressing the arrangement of the flat Dampfungs instituten and the mounting adapter to a flat portion of a fixedly connected to the electric motor support structure comprise releasable screws , Acting as an abutment of the fastener firmly connected to the electric motor Stutz structure can be easily by a corresponding design of the motor housing, which is usually carried out quite massively anyway provide.
- the support structure fixedly connected to the electric motor is a housing area surrounding the drive shaft of the wiper arrangement with a flat bearing surface.
- threaded holes can be introduced, in which engage the screws for fixing the mounting adapter.
- the fastening adapter is provided outside the central region, which is provided for the connection to the electric motor, with fastening means with the aid of which an attachment of the overall arrangement to a carrier-acting part can take place.
- This acting as a carrier part can be formed for example by the body of a vehicle.
- This can be realized in a particularly simple manner if the fastening adapter is provided outside the central region with fastening means with the aid of which a fastening of the overall arrangement to a part acting as a carrier can be effected with a perforated, engageable surface by click connection.
- a perforated, graspable catch can be provided, for example, in the area of the tailgate of a vehicle.
- the fastening adapter is a steel component which is formed by deep drawing.
- 1 is an exploded view of an inventive arrangement with a rear wiper motor and mounting adapter
- 2 shows a side view of a click connector as a fastening means for fixing the fastening adapter to a perforated body panel
- Fig. 3 is a plan view of an identical click connector.
- FIG. 1 shows an exploded view of an inventive arrangement with a rear wiper motor in a housing 1 and a mounting adapter 2. Visible is a drive shaft 3, which is surrounded by a fixed to the housing 1, and thus also connected to the electric motor support structure 4.
- This support structure 4 is designed as a housing area surrounding the drive shaft 3 of the wiper arrangement in the form of a cylindrical surface with a flat bearing surface 5.
- threaded holes 6 are introduced, in which screws 7 can engage the attachment of the mounting adapter 2 on the housing 1 of the rear wiper motor.
- the mounting adapter 2 itself is designed as a steel component, which is formed by deep drawing. In the present example, the mounting adapter is designed largely in the form of a flat surface.
- the mounting adapter 2 is adapted in a central region to the geometry of the support structure 4, here in the form of a flat surface.
- Disc-shaped elastic damping elements 8, 8 'of rubber are arranged on both sides of the central region of the fastening adapter 2.
- the arrangement of damping elements 8, 8 'and mounting adapter 2 is pressed in the assembled state by the screws 7 against the support surface 5, wherein the damping elements 8, 8' are at least partially elastically compressed.
- the arrangement additionally comprises a clamping plate 9 which, for a more uniform application of force into the stack arrangement of the Dampfungs instituten 8, 8 'and the mounting adapter 2 provides.
- Steaming elements 8, 8 ', mounting adapter 2 and clamping plate 9 are each provided with a central opening through which the drive shaft 3 of the wiper arrangement passes, which is required for internal mounting of the wiper drive.
- the bearing surface 5 is provided with bolt-shaped centering aids 10 which ensure an exact positioning of the damping element 8 by engaging in corresponding openings 11 in the damping element 8.
- the mounting adapter 2 is also provided in its central region with raised longitudinal centering 12, which can be brought into engagement with corresponding elongated holes in both Dampfungs instituten. In this way, a defined arrangement of the damping elements 8, 8 'and of the mounting adapter 2 with respect to the bearing surface 5, which is subsequently fixed by the screws 7, already results during assembly.
- the geometric adaptation to different installation space is carried out exclusively by varying the Befest Trentsadap- ter 2.
- This variation of the mounting adapter is made outside the connection region between the electric motor, so the support surface 5, and the mounting adapter 2.
- the central region of the mounting adapter however, always carried out in the same way.
- the clamping plate 9 and the Befest Trentsadap- ters 2 can be a very stable preassembled assembly of a wiper drive realize in the impermissible relative movements between the individual components can be largely excluded.
- the attachment of the preassembled module to the vehicle body is effected by fastening elements 14, which are arranged on the edge region of the fastening adapter. Sufficient extension of the fastening adapter makes it possible to ensure that even relatively weak fastening elements 14 are sufficient to absorb torques occurring, since the fastening elements are arranged at a sufficient distance from the axis of rotation.
- resilient detents are used in the present case, which make it possible to produce a click connection to body surfaces with corresponding bores.
- This system allows a very simple final assembly, which includes a mounting of the preassembled module by simply pressing against a provided with the appropriate holes body surface.
- the connection is reversible if a possibility for unlocking is provided, which represents a further advantage in the event of a necessary conversion.
- the use of resilient detents as fasteners also has the advantage that can be absorbed by shock acting shear forces elastic, without causing a permanent mispositioning of the wiper drive.
- FIG. 2 is a side view of a sectional view, wherein FIG. 3 shows the profile AA 'of the sectional plane.
- the resilient locking comprises several splayed and thereby elastically deflectable metal strips.
- the body panel 15 is provided in the region of the click connection with an opening 16.
- the resilient detent 14 is inserted from the motor side.
- locking metal strip 17 is initially elastically deflected by the edge of the opening 16 until a locking surface 18 is guided through the opening.
- this locking surface 18 is placed in the final position of the lock 14 in front of the outside of the body panel 15, whereby the form gleichige lock is produced.
- further metal strips 19 are in contact with the inside of the body panel 15 on the motor side. These metal strips 19 form an end stop when the lock is arranged in the opening 16.
- a play-free attachment results when the metal strips 19 reach the end position already subject to an elastic deflection.
- the restoring forces acting in the locked state can be so dimensioned that forces to be absorbed do not lead to a loosening of the connection or to a rattling.
- An extending through the opening 16 extension 20 allows easy unlocking of the connection when a removal of the wiper drive should be required.
- the inventive system results in a significantly reduced effort for adjustments and construction, if different mounting points are required for a wiper system, the motor side is operated with a uniform interface. This results in lower tooling costs and the possibility of faster implementation of new specifications into mountable assemblies. Low noise levels in the passenger compartment and low wiper angle tolerances are further advantages of the exemplary arrangement.
