Function expansion assembly and electronic device having the function expansion assembly

An electronic device, comprising:

• a host, comprising an opening, a fixing portion corresponding to the opening, and a corner defined by two adjacent sides, wherein the opening crosses the two adjacent sides at the corner;
• and
• a function expansion assembly, comprising:
• a functional module, comprising an expansion circuit board and an expansion connector disposed on the expansion circuit board, the expansion circuit board being detachably fixed at the fixing portion so that the functional module is replaceable through the opening;
• and
• an anti-collision module, comprising a covering and a lid, the covering being detachably fixed at the host and covering the opening, the covering having an insertion slot, the lid corresponding to a position of the insertion slot and being connected in a liftable and covering manner to the covering, and the lid blocking the expansion connector by covering the insertion slot,
• wherein when the covering of the anti-collision module covers the opening, the insertion slot is positioned to align with the expansion connector, allowing an external electronic connector to connect threrethrough.

An electronic device, comprising:

• a host, comprising an opening and a fixing portion corresponding to the opening, wherein the host includes an observe side and a reverse side opposite to each other and a plurality of lateral sides adjacent to the observe side and the reverse side, and wherein the opening crosses the reverse side and one of the lateral sides;
• and
• a function expansion assembly, comprising:
• a functional module, comprising an expansion circuit board and an expansion connector disposed on the expansion circuit board, the expansion circuit board being detachably fixed at the fixing portion so that the functional module is replaceable through the opening;
• and
• an anti-collision module, comprising a covering and a lid, the covering being detachably fixed at the host and covering the opening, the covering having an insertion slot, the lid corresponding to a position of the insertion slot and being connected in a liftable and covering manner to the covering, and the lid blocking the expansion connector by covering the insertion slot, allowing an external electronic connector to connect threrethrough.
