METALLIC HOUSING OF ELECTRONIC DEVICE AND MANUFACTURING METHOD THEREOF

摘要

A metallic housing of an electronic device includes a metallic outer case and an inner structural member embedded in the inner side of the outer case by die-casting. The outer case includes a bottom plate and a peripheral sidewall. The bottom plate is equipped with a number of latching hooks. The latching hooks are spaced from each other. The peripheral sidewall defines a receiving groove at an inner side along the peripheral sidewall. The inner structural member is made of metal alloy, and includes a base plate and a frame sidewall surrounding a periphery of the base plate, a protruding flange protruding from the frame sidewall, and a plurality of combining grooves on the base plate. The protruding flange is received in the receiving grooves, and the number of latching hooks is respectively received in the number of combining grooves.
