Electronic parking lock actuator for automatic transmission of vehicle
First Claim
1. An electronic parking lock actuator, comprising a driving motor and a gearbox coupled to the driving motor, the gearbox comprising:
- a casing comprising a base and a cover mounted on the base, the base comprising a bottom plate, and a plurality of peripheral walls extending upward from edges of the bottom plate, the bottom plate defining at least one cavity;
a gear rotatably received in the casing and connected to the driving motor for outputting a driving force generated by the driving motor; and
a controller fixed in the casing, and comprising a printed circuit board and a plurality of electronic components disposed on a side of the printed circuit board facing the bottom plate, the electronic components being received in the at least one cavity to cause the electronic components and the gear to overlap at least a portion of in an axial direction of the gear;
wherein the bottom plate of the casing further defines a receiving space receiving the gear, the receiving space is not in communication with the at least one cavity;
