Abstract
A camera module includes a body having recesses in a first datum surface. A filleted edge may join the recesses to the first datum surface. An image sensor is coupled to the body at a known distance from the first datum surface. A movable lens mechanism includes a fixed portion and a movable portion. The fixed portion is coupled to the body. The movable portion includes a lens assembly and protrusions arranged to fit within the recesses in the first datum surface and to define a second datum surface. A resilient stop plate covers the recesses in the first datum surface with an elastic sheet material. A spring may hold the protrusions in contact with the resilient stop plate when the movable lens mechanism is unpowered. The resilient stop plate may include a rigid support plate coupled to the body by heat staking. The elastic sheet material may be viscoelastic.
