An electronic device is provided. The electronic device includes a housing having an insertion slot, a connecting interface, and an adaptor card. The connecting interface is disposed in the housing for connecting with a first electronic module or a second electronic module separately and has a first connecting part and a second connecting part. The adaptor card is detachably disposed in the housing and includes a flow guide. When the electronic device is in a first mode, the first electronic module is connected to the first connecting part, and the adaptor card is disposed between the insertion slot and the connecting interface. The flow guide directs an airflow toward the first electronic module. When the electronic device is in a second mode, the adaptor card is removed from the housing, and the second electronic module is connected to the first connecting part and the second connecting part.

A clamping member and a battery accommodating device are provided. The battery accommodating device includes a body and a clamping member pivotally connected to the body. The clamping member has two arm parts, two protruding parts respectively extending from one side of the two arm parts, and an elastic structure connected to the two arm parts at two ends. When the battery is placed in an accommodating slot of the body, the elastic structure is pressed by the battery, and one end of the battery is clamped between the two protruding parts and the elastic structure. When the two protruding parts are pushed by an external force, the clamping member rotates relative to the body, and the elastic structure pushes up the battery, so as to release the clamped end of the battery.
