Abstract
A self-aligning lens holder includes elements that register against an image sensor chip to align the holder and lens with the chip. The elements may deflect or deform. A corresponding method aligns the lens holder and a fisheye lens to the image sensor.
Claims21
A self-aligning camera assembly comprising:
- a circuit board;
- a solid state image sensor mounted to a circuit board;
- a lens holder including a base and a shaft, the lens holder base including registration elements that are adapted to register the lens holder relative to the image sensor upon engaging the lens holder with the image sensor, thereby aligning the lens holder with the image sensor;
- each one of the registration elements engages a corresponding surface of the image sensor and is adapted for deflecting relative to the shaft of the lens holder upon engagement with the surface of the image sensor;
- screws coupling the base of the lens holder to the circuit board;
- and
- a lens coupled to the lens holder.

The camera assembly of 4 wherein the bevel surface is an undercut.
A method of assembling a camera to a circuit board, comprising the steps of:
- (a) mounting a solid state image sensor to a circuit board;
- and
- (b) engaging the image sensor with a lens holder, including contacting the image sensor with registration elements of the lens holder to align the lens holder
- with the image sensor, the engaging step including deflecting of the registration elements relative to a shaft of the lens holder upon contacting the image sensor with the registration elements.
1 more element
A camera assembly comprising:
- a circuit board having at least a pair of through holes;
- a solid state image sensor mounted to a circuit board between the through-holes;
- a lens holder including a base, a shaft extending upwardly from the base, and shoulders proximate the shaft;
- the lens holder base including registration elements that register the lens holder relative to the image sensor upon engaging the lens holder with the image sensor, thereby aligning the lens holder with the image sensor;
- a lens mounted in a bore of the shaft of the lens holder;
- and
- a spring bracket including:
- a pair of opposing, resilient legs located in the through-holes in the circuit board;
- v-spring portions extending inwardly from the legs and engaged with the shoulders of the lens holder;
- and
- a top plate extending from the v-spring portions and adapted for transmitting an upward force from the v-spring portions to the lens.
