Shock damping of optical lens components
First Claim
Patent Images
1. An optical lens assembly for an electronic equipment comprising:
- a shock absorbing mount within a housing of the electronic equipment; and
an optical lens group supported by the shock absorbing mount;
wherein the shock absorbing mount permits relative movement between the optical lens group and the electronic equipment to absorb shock energy; and
wherein the shock absorbing mount includes a sleeve member mounted to the electronic equipment in which an optical lens package is supported for sliding axial movement relative to the sleeve member, the optical lens package supporting the optical lens group, and wherein the sleeve member is generally sealed but includes at least one passageway for permitting fluid to flow into and out of the sleeve in response to movement of the optical lens package within the sleeve member.

Abstract
A shock and/or vibration damped optical lens assembly for electronic equipment. The optical lens assembly of the present invention is particularly useful for electronic equipment such as mobile phones, PDA'"'"'s, etc. incorporating cameras. By providing a shock and/or vibration damped optical lens assembly allows such devices to more reliably implement auto-focusing and/or zoom lens packages. Accordingly, the present invention facilitates the use of more advanced lens packages in hand-held electronic equipment such as cell phones, PDA'"'"'s etc.

17. An optical lens assembly for an electronic equipment comprising:
-
a shock absorbing mount within a housing of the electronic equipment; and an optical lens group supported by the shock absorbing mount; wherein the shock absorbing mount permits relative movement between the optical lens group and the electronic equipment to absorb shock energy; and
wherein the shock absorbing mount includes a sleeve member mountable to the electronic equipment in which an optical lens package including the optical lens group is supported for sliding axial movement relative to the sleeve member, wherein the optical lens package forms a seal with the sleeve member thereby dividing the sleeve member into two separate chambers, and wherein at least one passageway connects the separate chambers for permitting fluid to flow between the chambers in response to movement of the optical lens package within the sleeve member. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
