Embodiments of this application provide a middle frame, a battery cover, and an electronic device. The electronic device may include a mobile or fixed terminal with an edge frame or a housing, such as a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, a walkie-talkie, a netbook, a POS machine, a personal digital assistant (PDA), an event data recorder, a wearable device, a virtual reality device, a wireless USB flash drive, a Bluetooth speaker/headset, or a vehicle-mounted device. Two types of materials: ceramics and plastic, are used to form a middle frame and a battery cover, thereby reducing a weight of the electronic device. This resolves a problem that is of a relatively large weight of an existing electronic device and that is caused when a pure ceramic middle frame and a pure ceramic battery cover are used in the electronic device.

A computing device is disclosed. The computing device has a frame including a recessed battery compartment, the recessed battery compartment having a rigid back surface. The computing device further has a closure member having a rigid portion and a flexible portion, wherein a periphery of the closure member is coupled to a peripheral edge of the recessed battery compartment, the flexible portion to permit the rigid portion to move relative to the frame. The computing device further has a battery coupled to one or more of the battery compartment and the closure member, the battery oriented between and substantially adjacent to the rigid back surface of the battery compartment and the closure member.

Power supply device includes: battery stack in which a plurality of battery cells each including, on a top surface thereof, gas discharge valve that opens when an internal pressure of outer covering can increases are stacked; first cover provided on a top surface of battery stack and defining first gas duct communicating with gas discharge valve; and second cover provided on a top surface of first cover and defining second gas duct on a top surface of first gas duct. A plurality of communication holes through which first gas duct and second gas duct communicate with each other are formed on the top surface of first cover.
