Definitions
- Drive units for automotive applications are used for a variety of adjusting movements in or on the motor vehicle. These include, for example, a window lifter drive, electric seat adjustment, mirror adjustment, unlocking and locking for tailgates, front hoods, etc., unlocking and locking for tank flaps, loading flaps on electric or hybrid vehicles, etc. to name just a few examples.
- locking system drive units that is to say drive units that are used in connection with locking systems, that is to say, for example, are designed as part of a closing drive. Very particularly before given it is about drive units inside or on motor vehicle locksmiths and in particular motor vehicle door locks.
- the invention is based on the technical problem of developing such a drive unit for automotive applications and in particular a locking system drive unit so that movements of the electric motor inside the housing are reduced to a minimum and consequently the functional reliability and service life can be significantly increased.
- the cover and the housing can also be coupled to one another via a circumferential tongue and groove connection.
- the tongue-and-groove connection can adapt to the cage, which as it were enclosing the electric motor, made up of the usually four fixing anchors
- the tongue and groove connection is usually designed in two parts with a labyrinth surface and a web engaging in it.
- the labyrinth surface is generally realized on the edge of the cover, while the web is on the edge of the housing. In principle, it is also possible to proceed in reverse. In this case, the labyrinth surface is provided on the edge of the housing, while the web is arranged on the edge of the cover.
- the invention recommends that the cover and / or the housing have one or more raised bearing surfaces in the central area.
- these support surfaces can each be placed between the respective fixing anchor and the recess on both sides of the recess, so that in the central area in question a cuboid reinforcing cage described by the four fixing anchors is provided and implemented, which overall ensures that the housing closing lid is practically not deformed in this area, even if restoring torques act on the electric motor in the course of its actuation.
- FIGS. 1 and 2 The comparative consideration of FIGS. 1 and 2 makes it clear that in each case two fixing anchors 7, 8 are arranged on both sides of the associated recess 5, 6 directly adjacent thereto. In fact, the two fixing anchors 7, 8 are found on both sides and opposite to a plane of symmetry S, on which the electric motor 3 is also arranged and is received by the two recesses 5, 6.
- the four fixing anchors 7, 8 in the example and according to the embodiment shown define a central area 9 of the housing 1, 2.
- This central area 9 of the housing 1 as well like the cover 2 is designed to be particularly stiff.
- the predominantly flat character of the housing 1 as well as of the cover 2 in this central area 9 also contribute.
- the cage formed in this way in the central area 9 ensures that the electric motor 3 with the help of the fixing anchor 7, 8 and the recesses 5, 6 receiving it is properly and permanently fixed, as already described in the introduction.
- the housing 1 and the cover 2 are additionally coupled to one another via a circumferential tongue and groove connection 12, 13.
- the tongue and groove connection 12, 13 is equipped in two parts with a labyrinth surface 12 and a web 13 engaging therein.
- the labyrinth surface 12 is located on the edge of the cover 2.
- the web 13 is provided on the edge of the housing 1.
- the labyrinth surface 12 is connected via an elastically yielding area 14 to the relatively rigid central area 9 of the cover 2 or the cover 2 and the housing 1.
- This elastically yielding area 14 is defined in the exemplary embodiment in that indentations 15 are implemented and provided in this area in the cover 2 on both sides of the rigid central area 9.
- the elastically yielding area 14 can alternatively or additionally be realized and implemented by resorting to a different plastic during the manufacture of the cover 2.
- the cover 2 like the housing 1, is typically made of a thermoplastic.
- the elastically yielding area 14 there is also the possibility of using an elastomer at this point.
- the two indentations 15 shown in FIG. 1 as components of the elastically yielding area 14 are sufficient to provide the necessary elasticity for the elastic area 14.
- the cover 2 or the housing 1 in the example in the central area 9 are additionally equipped with raised contact surfaces 16. These raised bearing surfaces 16 are each located between the respective fixing anchors 7, 8 and the recess 5, 6.
- the raised bearing surfaces 16 provided at this point also ensure that the electric motor 3 is in the area of the cage defined by the fixing anchors 7, 8, respectively in the central area 9 experiences a particularly rigid and permanent fixation and is subject to a press fit, as it were.
