Electromotive drive for motor vehicle applications
An electromotive drive for motor vehicle applications. In particular, the electromotive drive is part of a locking device of an electric connection device for electric or hybrid motor vehicles. For this purpose, an electric motor and a multistage transmission which is arranged downstream of the electric motor are provided as drive elements for acting on an actuating element, and a drive housing which houses drive elements is also provided. The actuating element is a locking element of the locking device for example. The drive housing is equipped with inner and/or edge-side protrusions. The protrusions have direct bearing points for individual drive elements or all of the drive elements.
1. An electromotive drive for automotive applications, the electromotive drive being a component of a locking device of an electric connection device for electric or hybrid vehicles, the electromotive drive comprising:
an electric motor,
a multistage transmission arranged downstream the electric motor and including drive elements for acting upon a locking element of the locking device, and
a drive housing which houses the drive elements, wherein the drive housing is equipped with inner and/or edge-side protrusions which have direct bearing points for at least one of the drive elements,
wherein the locking element includes a stepped projection, wherein the projection comprises a first contact surface and a second contact surface spaced apart from the first contact surface, wherein the stepped projection engages a corresponding recess formed when a charging plug engages a charging plug socket in a locked state.
2. The electromotive drive according to claim 1 , wherein the drive elements include stationary drive elements, and wherein the inner and/or edge-side protrusions are equipped with the direct bearing points for the stationary drive elements.
3. The electromotive drive according to claim 1 , wherein the drive elements include movable drive elements, and wherein the inner and/or edge-side protrusions are equipped with the direct bearing points for the movable drive elements.
4. The electromotive drive according to claim 1 , wherein the inner and/or edge-side protrusions are formed integrally on the drive housing.
5. The electromotive drive according to claim 4 , wherein the inner and/or edge-side protrusions and the drive housing are formed as a one-piece plastic molding.
6. The electromotive drive according to claim 1 , wherein the inner and/or edge-side protrusions are configured as housing ribs on the drive housing.
7. The electromotive drive according to claim 6 , wherein the housing ribs have an extent in a transverse direction by comparison with an axial direction of an associated one of the drive elements.
8. The electromotive drive according to claim 1 , wherein the direct bearing points are configured for axially and/or radially securing the drive elements.
9. The electromotive drive according to claim 1 , wherein the bearing points are each opened in an installation direction of the drive elements.
10. The electromotive drive according to claim 1 , wherein the drive housing includes a lower shell including the inner and/or edge-side protrusions, and an upper shell which closes the lower shell as a closure for the lower shell.
11. The electromotive drive according to claim 1 , wherein the bearing points are configured for reinforcement and/or stabilization of the drive housing.
12. The electromotive drive according to claim 1 , wherein the drive elements include stationary drive elements and movable drive elements, and wherein the direct bearing points of the inner and/or edge-side protrusions are configured to accommodate the stationary drive elements and the movable drive elements.
13. The electromotive drive according to claim 12 , wherein the movable drive elements include shafts of the multistage transmission, each of the shafts defining a stage of the multistage transmission.
14. The electromotive drive according to claim 13 , wherein the shafts extend parallel to each other and the inner and/or edge-side protrusions extend transversely relative to the shafts.
15. The electromotive drive according to claim 12 , wherein the movable drive elements and the inner and/or edge-side protrusions are both formed of plastic.
16. The electromotive drive according to claim 12 , wherein the stationary drive elements include the electric motor.
17. The electromotive drive according to claim 1 , wherein the direct bearing points have a U-shaped cross section.
18. The electromotive drive according to claim 7 , wherein the housing ribs are spaced relative to each other.
19. The electromotive drive according to claim 18 , wherein all of the housing ribs extend in the transverse direction.
