An electronic device is provided, including a first module, a second module movable relative to the first module, and an elastic component. The second module has a slot and a convex surface on opposite sides thereof, wherein a sliding portion of the first module is movably received in the slot. When the second module moves relative to the first module to a closed or open position, the sliding portion abuts a first or second end surface of the slot. The elastic component is disposed in the first module and has a retractable end portion contacting the convex surface. When the second module moves with respect to the first module, the end portion slides along the convex surface and exerts an elastic force on the second module.
