Electrically-activated hood latch and release mechanism |
摘要 |
A latch assembly includes a latch movable between released and restrained positions and a latch spring biasing toward the released position. A first lever is movable between open and closed positions, corresponding to the released and restrained positions, respectively. A first lever spring biases toward the closed position. A second lever is movable between unlocked and locked positions, corresponding to the first lever open and closed positions, respectively. A second lever spring biases toward the locked position. An active material based actuator selectively moves the second lever from the locked to unlocked position in response to an activation signal. A primary activation mechanism selectively produces the activation signal without a mechanical connection to the passenger compartment. An auxiliary activation mechanism does not rely on the vehicle power system. A key or portable energy storage device may cause the activation signal from the primary or auxiliary activation mechanism.
