Abstract: A battery cover includes an inner assembly and an outer assembly. The inner assembly includes an upper board defining an L-shaped groove, a bottom board screwed connected with the upper board; and a metal dome fixed between the upper board and the bottom board to pass throughout the bottom board for contacting the battery compartment. The outer assembly includes a front cover defining a first opening thereon, a slide button receiving in the first opening and the L-shaped groove of the upper board to slidably move along the L-shaped groove.

Abstract: A battery cover for connecting to a portable electronic device pivotably via a pivot, includes a front cover, a bottom board connected to the front cover and a metal dome fixed between the front cover and the bottom board. The front cover includes a main body, a slide board, a resilient member and a fixing mat. The main body defines a front end adjacent to the pivot and a rear end opposite to the front end. An opening is disposed on the rear end and a first positioning groove is disposed between the front end and the opening. The slide board includes an operation button exposed out of the opening and is operable for slidably engaging with or disengaging from the portable electronic device. The resilient member is received in the first positioning groove and connecting to the slide board. The fixing mat is configured for fixing the slide board and resilient member on the main body.
