Abstract: An unlocking apparatus which includes a circuit board, a snap-on structure, and a shape memory alloy strip. The circuit board is configured to supply power to the shape memory alloy strip, the snap-on structure is fixedly connected to the shape memory alloy strip, and after being powered on, the shape memory alloy strip deforms, so that the snap-on structure is driven to move and to be unbuckled from a card slot of a locked component. In the foregoing structure, components for driving unlocking are merely the shape memory alloy strip and the circuit board supplying power to the shape memory alloy strip, greatly simplifying the entire unlocking structure.

Abstract: An electrical connection structure includes a body-end connection apparatus and a band-end connection apparatus. A first metal connection terminal included in the body-end connection apparatus is disposed on a first frame; a first sealing apparatus is configured to perform sealing between the first frame and the wearable device; a second frame included in the band-end connection apparatus is configured to connect to a band of the wearable device; and a second metal connection terminal is disposed on a frame and electrically connected to the band of the wearable device. When the band of the wearable device is connected to a body, the first metal connection terminal is electrically connected to the second metal connection terminal, the first frame clutches the second frame, and the second sealing apparatus is configured to perform sealing between the first frame and the second frame.
