Embodiment Construction

[0021] refer to figure 1 , a car 14 is shown including a door 10 movable between open and closed positions. The vehicle door 10 is locked in a closed position by an electro-mechanical locking mechanism 15 . The electro-mechanical locking mechanism 15 may include a user-actuated switch assembly 22, a controller 20 (such as a computer); a solenoid 18 (or, alternatively, an electric motor), and a mechanical lock 16 (which may act with the solenoid 18 as a as a whole or not as a whole).

[0022] In order to open the vehicle door 10, the locking mechanism 15 locking the vehicle door 10 must first be released. Release of the latch mechanism 15 is triggered by manual actuation of the switch assembly 22 by the user. Switch assembly 22 provides low current switching to ground. The controller 20 monitors the switch assembly 22 for state changes. When the controller 20 receives the ground signal input by the switch assembly 22 , the controller 20 operates the solenoid 18 to disengag...

Abstract

A switching apparatus and electro-mechanical latching system includes an elastomeric button with independently movable electrically conducting spring plates mounted to the button. The button includes a plurality of elastomeric posts extending from an inboard surface thereof for retaining the spring plate to the button. A leadframe is disposed in the base and includes electrical tracks for communicating with a vehicle computer. Each spring plate includes a plurality of cantilever springs. When the button is depressed, the cantilever springs of the spring plates come in contact with electrical tracks to complete a circuit. The completion of the circuit causes a signal to be sent to a vehicle computer, which signals a motor to release the automotive vehicle door latch.

Description

technical field [0001] The present invention relates generally to door locks for automotive and other vehicle applications, and more particularly to a switch assembly for an electro-mechanical door lock mechanism. Background technique [0002] Traditionally, mechanical devices have been used to lock and unlock similar closures such as doors, trunks, hoods, liftgates and hatches in automobiles and other vehicles. As a means of alleviating the force required to operate such closures, electro-mechanical door locking mechanisms are known. For example, a user actuated switch may be employed to trigger the release of the mechanical lock. In this regard, when an electric switch is actuated, it can be used to provide input to the controller to operate the mechanical lock. In addition, the physical structure of the switch can be specified as required by modern style and ergonomics. For example, a switch may need to include an aesthetically pleasing user-actuated portion (e.g., an ...
