Embodiment Construction

[0029] like figure 2 and image 3 As seen in , the electric motor 34 includes an output shaft 36 that drives a worm 38 mounted to the outer end of the shaft. The device comprises a worm wheel 40 meshing with the worm, a helical spring 42, and a camshaft 44 on which the output cam 28 is mounted. As described in detail below, these components are arranged such that the spring biases the worm gear, which in turn causes the output cam to rotate in a counterclockwise direction (from Figure 1 and image 3 center view) biased toward the closed position. The motor runs, and the worm wheel is driven to rotate clockwise through the worm, that is, to rotate toward the open position shown in FIG. 1b.

[0030] The electric motor 34 is a high output torque, low backlash torque 200 series motor with integrated thermal protection, EMC protection and a knurled shaft. Such motors are commercially available, for example, from Mabuchi Motor Co., Ltd or Johnson Electric North American, Inc. ...

Abstract

A power actuator for automotive door latches. The actuator includes an electric motor mounted in a housing. A worm is operatively coupled to the motor for driving rotation of the worm about an axis in a first rotational direction. A worm gear, which meshes with the worm, is mounted in the housing for rotation about an axis substantially orthogonal to the worm axis. A camshaft is mounted on the worm gear and has a rotation axis coincident with the gear axis. An output arm is affixed to the distal end of the camshaft for engaging the lever of a latch. The power actuator uses a reduced number ofcomponents.

Description

technical field [0001] The present invention generally relates to a device for releasing a latch, that is to say a powered actuator for a car latch, such as a powered actuator for releasing a trunk Powered actuator for movement between locked and unlocked positions. Background technique [0002] Cost is an important factor in the manufacture of automotive accessories such as electric latch releases. The number of components making up the powered actuator has an impact on product cost. Thus, known powered actuators for automotive closing latches have more components and therefore have a higher cost than the present invention. Contents of the invention [0003] A powered actuator for a latch of an automotive closure according to a preferred embodiment of the present invention has a lower number of parts than similar devices currently on the market. [0004] According to one embodiment of the present invention, there is provided a powered actuator comprising: a housing;...
