Title
(EN) MULTIPLE LAYER FLEXURE FOR SUPPORTING A MOVING IMAGE SENSOR
(FR) FLEXION MULTICOUCHE POUR SUPPORTER UN CAPTEUR D'IMAGE MOBILE
Abstract
(EN)
Some embodiments may include a multi-layer flexure that may be used in an optical image stabilization voice coil motor (OIS VCM) actuator of a camera. The multi-layer flexure module may include a dynamic platform and a static platform along with multiple layers of flexure arms that mechanically connect the dynamic platform to the static platform. In some examples, the multi-layer flexure may include electrical traces configured to convey signals from the dynamic platform to the static platform. The electrical traces may be routed from the dynamic platform to the static platform via the flexure arms. In some embodiments, a multi-layer flexure may have a greater stiffness in a Z-direction aligning with an optical axis of a camera and may have a lower stiffness in X and Y directions corresponding to optical image stabilization directions of an OIS VCM actuator.

L'invention concerne selon certains modes de réalisation une flexion multicouche qui peut être utilisée dans un actionneur d'un moteur à bobine mobile pour stabilisation optique d'image (OIS VCM) d'une caméra. Le module de flexion multicouche peut comprendre une plateforme dynamique et une plateforme statique conjointement à de multiples couches de bras de flexion qui relient mécaniquement la plateforme dynamique à la plateforme statique. Dans certains exemples, la flexion multicouche peut comprendre des tracés électriques conçues pour transporter des signaux de la plate-forme dynamique à la plate-forme statique. Les tracés électriques peuvent être acheminées de la plate-forme dynamique à la plate-forme statique par l'intermédiaire des bras de flexion. Dans certains modes de réalisation, une flexion multicouche peut avoir une rigidité supérieure dans une direction Z alignée avec un axe optique d'une caméra et peut avoir une rigidité inférieure dans les directions X et Y correspondant à des directions de stabilisation d'image optique d'un actionneur OIS VCM.
