Abstract
A motor assembly that is useful for operating various devices on a vehicle includes a unique arrangement for securing a detector arrangement within the motor assembly. The detector arrangement includes a first portion that is supported on a shaft associated with the rotor portion of the assembly. A second portion of the detector arrangement is supported by a flange, which is associated with the stator of the assembly. The second portion of the detector assembly includes a printed circuit board that is received within a recessed housing formed on the flange. The recessed housing includes at least one surface that abuts the circuit board into a position where cooperating locking features operate to secure the printed circuit board in a desired position on the flange.
Claims15
An actuating motor including a stator in which a rotor is arranged, the stator including at each of its ends, a flange for (guiding the corresponding end of a shaft linked to the rotor, each guide flange including a guide bearing configured to support a corresponding end portion of the shaft when the flange is assembled onto the stator, and means for detecting the rotation of the shaft comprising a first portion carried by the shaft and a second portion carried by a corresponding flange, the second portion of the detection means arranged on a printed circuit board that is engaged by at least one surface in a corresponding recessed housing formed as part of the flange, the flange and the circuit board include means for complementary locking in assembled position by elastic clipping, the surface in the recessed housing abutting the circuit board into a position where the complementary locking means operates to secure the board in a desired position, said complementary locking means including a tab on one of said board and said recessed housing, and an opening in the other, said tab extending into said opening to secure said board as recited.
An actuating motor assembly, comprising:
- a stator having two ends with a flange at each of the ends;
- a rotor supported within the stator;
- a shaft linked to the rotor, the shaft being guided by the flanges, each flange including a guide bearing that supports a corresponding end portion of the shaft when the flange is assembled onto the stator;
- a detector arrangement that detects rotation of the shaft and includes a first portion supported on the shaft and a second portion supported on one of the flanges, the second portion of the detector arrangement being supported on a printed circuit board;
- the one flange including a recessed housing that receives the printed circuit board and includes at least one surface that abuts the printed circuit board;
- and
- a locking tab on one of the circuit board or the recessed housing on the flange for locking the circuit board within the recessed housing, the one surface in the recessed housing abutting the circuit board into a position where the locking tab operates to secure the circuit board in a desired position, said locking tab moving into a recess in the other of said circuit board and said recess housing to achieve said securement of said circuit board in a desired position.
