Abstract
In one aspect of this invention, an actuator includes a motor having an output worm shaft, a transmission mechanism operatively coupled to the output worm shaft of the motor for converting a rotating motion of the motor into a linear reciprocating motion, a housing and mounting means for mounting the motor in the housing, where the transmission mechanism is devoid of a coil spring, and the mounting means is devoid of a foam plastic block.
Claims10
An actuator for converting a rotating motion into a linear reciprocating motion, comprising:
- (a) a motor having a front end and an output worm shaft extending from the front end;
- (b) a transmission mechanism operatively coupled to the output worm shaft of the motor for converting a rotating motion of the motor into a linear reciprocating motion, wherein the transmission mechanism is devoid of a coil spring;
- and
- (c) a housing and mounting means for mounting the motor in the housing, wherein the mounting means is devoid of a foam plastic block,
- wherein the transmission mechanism comprises:
- a bracket mounted onto the front end of the motor, having a base, and a fixing pin extending from the base along a direction perpendicularly to the worm shaft of the motor;
- a worm wheel having a first side, an opposite, second side, and a polygon-shaped recess defined in the second side, the worm wheel attached onto the base through the fixing pin on the first side, and meshing with the worm shaft of the motor;
- a connector having a first end portion and a second end portion extending oppositely from the first end portion, the first end portion formed in a polygon shape substantially complemental to that of the polygon-shaped recess such that the first end portion is tightly received in the polygon-shaped recess;
- and
- a cushion member placed between walls of the polygon-shaped recess of the worm wheel and the first end portion of the connector.
