The power unit according to the present invention is a unit for driving a windshield wiper linkage and / or direct drive of a windshield wiper arm. The power unit preferably comprises at least one electric motor and / or a transmission.
    [0002] The support unit according to the invention is a unit made to be coupled to the drive unit and the vehicle component. The fast coupling unit according to the invention is a unit for connecting the support unit and the power unit without tools by force and / or form connection and / or to couple them. Preferably, the fast coupling unit is without screws. A "tool-less" assembly according to the invention consists in using no tools. Finally, the term "intended for" when used, refers to a means specially designed and / or equipped to provide a certain function. Thus, the fact that an object is provided for a certain function means in particular that this object realizes and / or performs this function in at least one state of application and / or operation. According to another development of the invention, the fast coupling unit comprises at least one guide means for guiding the drive unit in a linear movement relative to the support unit in the mounting position. This allows a particularly simple mounting of the power unit on the support unit. Preferably, the guide means is provided on the support unit. In addition or alternatively, the guide means provides rotational guidance of the drive unit relative to the support unit for the mounting position. According to another characteristic, the drive unit comprises a drive shaft of the wiper arm and at least one guide means for guiding the drive unit to the mounting position, perpendicular to the axis. rotation of the drive shaft, which allows to connect the power unit to the support unit in a particularly secure manner. According to another characteristic, the fast coupling unit comprises at least one hook-shaped guiding means for picking up the motor unit at least in zones, from below. This ensures the coupling of the power unit to the support unit while allowing a compact implementation of the fast coupling unit. Advantageously, the guiding means forms a support hook. According to another feature, the rapid coupling unit has an oblong hole-shaped recess for receiving the drive unit in the mounted state, which makes it possible to reduce in a simple manner the clearance between the drive unit and the drive unit. support unit in the mounted state. Playback between the support unit and the drive unit is minimized if the rapid coupling unit has at least one friction element to block the drive unit by a frictional connection. Preferably, the friction element is on the support hook. According to another characteristic, the rapid coupling unit comprises at least one attachment means for effecting a locking by a connection by the shape of the driving unit, which advantageously avoids that the power unit runs the risk of accidentally detach from the support unit. According to another characteristic, the windscreen wiper drive device comprises at least one blocking means for blocking the fast coupling unit to prevent it from coming off. This provides a particularly strong operating safety. Preferably, the locking means is a rivet, a stud, ankle and / or a screw, which is a particularly advantageous solution.
    [0003] The invention also relates to a vehicle device equipped with a wiper drive device. The invention also relates to a method for mounting a windscreen wiper drive device according to which the power unit is fixed without tools to the support unit, thus enabling a particularly rapid mounting and simple from the power unit to the support unit. According to another feature, when mounted on the support unit, the drive unit is slid substantially perpendicular to the axis of rotation of the driving shaft of the drive unit relative to the support unit, which corresponds to a particularly fast and simple mounting of the power unit to the support unit. The wiper drive device according to the invention is not limited to the application and embodiment described above, but can be modified in number of components, elements or units relative to one another. to what has been described. Drawings The present invention will be described in more detail below with the help of a wiper drive shown in the accompanying drawings in which: FIG. 1 is a top view of a wiper drive device; wiper drive with a power unit and a support unit, Fig. 2 is a bottom view of the support unit of Fig. 1, and Fig. 3 is a perspective view of the drive device. of the wiper of Figure 1 before assembly.
    [0004] DESCRIPTION OF AN EMBODIMENT FIG. 1 shows a wiper drive device having a power unit 10 and a support unit 12. The wiper drive device is part of a wiper drive device. wiper not detailed. The support unit 12 serves to secure the drive unit 10 to a component 38 of the vehicle. In the mounted state, the support unit 12 is screwed to the component 38 of the vehicle. The support unit 12 is made of plastic. The component 38 of the vehicle is a part of the bodywork. The power unit 10 serves to drive a wiper linkage not shown. The power unit 10 comprises an electric motor 40 and a gearbox 42. The gearbox 42 connects the shaft of the electric motor 40 to the drive shaft 24 of the power unit 10. The drive shaft 24 is integrally rotatably coupled to a wiper arm 26.
    [0005] The support unit 12 comprises a quick coupling unit 14. This quick coupling unit 14 is fixed without tools to the drive unit 10. The quick coupling unit 14 connects the support unit 12 and the drive unit 10 in the mounted state by a connection by force and / or shape. The assembly is done without tools. The fast coupling unit 14 is made without screws. The rapid coupling unit 14 comprises four guide means 16, 18, 20, 22. The guide means 16, 18, 20, 22 are on the base body 48 of the support unit 12. The guide means 16, 18, 20, 22 are folded each close to its free end at an angle of 90 °. The guide means 16, 18, 20, 22 are taken by zone under the drive unit 10. The guide means 16, 18, 20, 22 each form a support hook. The guide means 16, 18, 20, 22 serve for the linear guidance of the drive unit 10 relative to the support unit 12 in the mounting position. The guiding means 16, 18, 20, 22 thus underlie a reception zone in the form of a semicircle. Two guide means 16, 22 among the guide means 16, 18, 20, 22 face each other. The two guide means 16, 22 each have a guide surface 44, 46. The guide surfaces 44, 46 are parallel. In this context, it is particularly possible to switch the driving unit 10 to the mounting on the support unit 12 around a tilting axis to arrive in the final mounting position. Fig. 2 shows in more detail the support unit 12. The quick coupling unit 14 has an oblong hole-shaped recess 30. The oblong hole-shaped recess 30 is in the base body 48 of the support unit 12. The oblong hole-shaped recess 30 receives the drive unit 10 in the mounted state. The drive unit 10 is applied against the wall delimiting the slot-shaped recess 30 in the mounted state. More specifically, the power unit 10 in the mounted state is applied against the envelope surface delimiting the slot-shaped recess 30 over a 180 ° zone. Figure 3 shows the power unit 10 and the support unit 12 before mounting. The drive shaft 24 has an axis of rotation 28 around which the drive shaft 24 rotates during wiping. The guide means 16, 18, 20, 22 guide the drive unit 10 perpendicular to the axis of rotation 28 of the drive shaft 24 in the mounting position. The guiding means 16, 18, 20, 22 each form a friction element 32 for blocking by a friction connection of the drive unit 10. For this purpose, the guiding means 16, 18, 20, 22 delimit each a receiving zone which is slightly smaller than the size of the portion of the power unit 10 to be received. In the assembled state, the power unit 10 is clamped in the guide means 16, 18, 20, 22. The support unit 12 has three fixing domes 50, 52, 54. The fixing domes 50, 52 , 54 serve to abut against three bearing chimneys 56, 58, 60 of the power unit 10. The fixing domes 50, 52, 54 each form an elongate guide for the chimneys 56, 58, 60. The chimneys 56, 58, 60 have a substantially truncated cone shape. With the guiding elements 16, 18, 20, 22, the fixing domes 50, 52, 54 also constitute a guiding means for the power unit 10. In this context, it is possible in principle also to realize the unit of support 12 without the fixing domes 50, 52, 54. The rapid coupling unit 14 comprises a hooking means 34. The hooking means 34 locks the drive unit 10 by a connection by the form. The attachment means 34 comprises a non-detailed hook which, in the mounted state, engages in a hooking recess of the drive unit 10. The wiper drive device further comprises a means for blocking 36. The locking means 36 blocks the quick coupling unit 14 to prevent it from becoming loose. The locking means 36 forms a screw. In the embodiment shown, the fast coupling unit 14 comprises precisely a hooking means 34. But in this context it is also possible to envisage that the quick coupling unit 14 comprises several hooking means. In principle, it is also possible to consider holding the drive unit 10 without attachment means 34 to the support unit 12 by a simple frictional connection between the guide means 16, 18, 20, 22 and the drive unit 10. For assembly, the support unit 12 is first brought closer to the drive unit 10 parallel to the axis of rotation 28. For this, the drive shaft 24 is guided in the recess in the form of an oblong hole 30. After the support unit 12 and the drive unit 10 come into abutment, the drive unit 10 is slid with respect to the support unit 12 perpendicularly to the axis of rotation 28. At this time, the guide means 16, 18, 20, 22 partially surround the power unit 10. The guide means 16, 18, 20, 22 strongly tighten the power unit 10. The attachment means 34 is deviated from his rest position. When arriving in the final position of assembly between the power unit 10 and the support unit 12, the attachment means 34 comes into the attachment recess of the power unit 10 by an elastic return. in the rest position. The drive unit 10 is applied flat against a portion of the envelope surface delimiting the slot-shaped recess 30. The attachment means 34 prevents the support unit 12 from becoming loose from the drive unit 10 Thus, the drive unit 10 is attached to the support unit 12 without the need for a tool. For the additional blocking, the locking means 36 are screwed into a non-detailed threaded recess of the drive unit 10. In the example presented, the windscreen wiper drive device comprises precisely a locking means 36. in this context, it can also be envisaged that the wiper drive device comprises several locking means. In principle, it is also possible to envisage a wiper drive device without blocking means. 5 8 NOMENCLATURE OF THE MAIN ELEMENTS 10 Driving unit 12 Support unit 14 Quick coupling unit 16, 18, 20, 22 Guide means 24 Drive shaft 26 Wiper arm 28 Rotor shaft 30 Oblong hole-shaped recess 32 Friction element 34 Clamping medium 36 Locking mechanism 38 Vehicle component 40 Electric motor 42 Gear unit 48 Base housing support unit 50, 52, 54 Fixing dome 56, 58, 60 Chimney 25
