An air baffle component includes an air baffle rotationally connected to a housing of a device chassis having a module insertion port. The air baffle component also includes a level-1 elastic component. The air baffle component further includes a level-2 elastic component. The air baffle component additionally includes a connecting rod. The connecting rod includes a force-bearing rod rotationally connected to the housing of the device chassis between the air baffle and the module insertion port. The connecting rod also includes a pull rod connected to the force-bearing rode. The connecting rod further includes a baffle column on the pull rod. The level-1 elastic component provides a first elastic force for the force-bearing rod, so that the baffle column is caused to abut against a surface of the air baffle opposite to the module insertion port. The level-2 elastic component provides a second elastic force for the air baffle.
