Back covers of electronic devices, and electronic devices

Abstract

The invention proposes a backplate for electronic devices and electronic equipment. The backplate of the electronic device consists of: a first structural layer comprising a first region and a second region, in which the thickness of the first region is greater than the thickness of the second region, the second region creates an orthogonal projection of the second region along the thickness direction of the electronic device, the battery of the electronic device creates an orthogonal projection of the battery along the thickness direction of the electronic device, and the orthogonal projection of the second region includes the orthogonal projection of the battery. The back cover is compatible with the middle frame of electronic devices with a glass back cover.
