Air baffle and calculation method of deformational stress thereof

摘要

An air baffle has elasticity and is disposed in an electronic device. The air baffle may be elastically deformed under a pressure exerted by an article. The air baffle includes a fixed section and at least one deformable section extending from a lateral side of the fixed section. The deformable section is arc-shaped and has a second-order deformation. A deformational stress of the deformable section is calculated using; $$ \sigma =\frac{\mathrm{FR}\left(\sin \theta \right)t}{2I},$$ ;and an allowable radius of curvature of the deformable section is determined, so as to keeping the deformational stress of the deformable section not exceeding a material yield stress of the air baffle.
