Motor Assembly for Automotive Air Vent Actuator

A motor assembly of an automotive air vent actuator, comprising:

• a stator assembly, the stator assembly including a stator housing having a first end and a second end;
• and
• a rotor assembly detachably connected to the stator assembly, the rotor assembly having a rotor shaft arranged along a first axis and detachably connected to the stator housing;
• a bearing;
• and
• an elastic member positioned near the second end of the stator housing and configured to support the rotor shaft,
• wherein the elastic member is configured to cooperate with the bearing and the second end of the stator housing to continuously apply an elastic force along the first axis to the rotor shaft through the bearing.

An automotive air vent actuator, comprising:

• an upper housing;
• a lower housing, the upper housing and the lower housing defining an installation cavity between them;
• a motor assembly disposed in the installation cavity, the motor assembly comprising:
• a stator assembly, the stator assembly including a stator housing having a first end and a second end;
• and
• a rotor assembly detachably connected to the stator assembly, the rotor assembly having a rotor shaft arranged along a first axis and detachably connected to the stator housing;
• a bearing;
• and
• an elastic member positioned near the second end of the stator housing and configured to support the rotor shaft, the elastic member defining a central bearing engagement hole surrounded by a plurality of evenly spaced limiting strips, and a peripheral portion including an annular positioning portion.
• wherein the elastic member is configured to cooperate with the bearing and the second end of the stator housing to continuously apply an elastic force along the first axis to the rotor shaft through the bearing.
