Manipulating center console components utilizing active material actuation
A center console comprising a manipulable structural component, such as a pivotal lid, sliding armrest, tambour door, or pivotal cup holder, and at least one active material actuator including an active material element operable to undergo a reversible change, drivenly coupled to the component, and configured to autonomously cause and/or enable the component to be manipulated as a result of the change.
1. A manipulable center console adapted for use in a vehicle, said console comprising:
a manipulable structural center console component;
a one-way shape memory alloy (SMA) wire actuator operable to undergo a reversible change in fundamental property when exposed to or occluded from an activation signal, so as to be activated and deactivated respectively, and operatively coupled to the component;
a spring-biased pawl intermediately coupled to the component and the one-way SMA wire actuator; and
a catch defined in a compartment coupled to the component, the catch to lockingly engage the spring-biased pawl when the component is in a closed condition;
wherein when the one-way SMA wire actuator is activated, the one-way SMA wire actuator disengages the spring-biased pawl from the catch to manipulate the component into an open condition.
2. The console as claimed in claim 1 , wherein the manipulable component is selected from the group consisting of a translatable top cover, a rollable top cover, a sliding armrest, a pivotal cup holder, a translatable cupholder, a sliding tambour door, a pivotal console lid, a reconfigurable interior compartment panel, and a translatable center console in the entirety.
3. The console as claimed in claim 1 , wherein the component is drivenly coupled to a stored energy element, the stored energy element is retained in a stored state when the spring-biased pawl is lockingly engaged, and the stored energy element is enabled to manipulate the component as a result of disengaging the spring-biased pawl.
4. The console as claimed in claim 3 , wherein the stored energy element is a spring drivenly coupled to the component.
5. The console as claimed in claim 4 , wherein the component is a pivotal lid, the lid defines a pivot axis, and the stored energy element is a torsion spring coaxially aligned with the axis and is in the stored state when the lid is closed.
6. The console as claimed in claim 1 , further comprising:
an input device communicatively coupled to the one-way SMA wire actuator, and operable to receive an input, wherein the input device and the one-way SMA wire actuator are cooperatively configured to manipulate the component only when the input is received.
7. The console as claimed as claim 6 , wherein the input device is selected from the group consisting of a push button, sliding gauge, wheel, touch screen, and microphone.
