Abstract: Provided is a wireless earphone case. The wireless earphone case includes a casing, a top cover, and a lock mechanism. An earphone slot is disposed in the casing. The top cover is slidably mounted on the opening end of the casing. The top cover has a closed position and an open position. The wireless earphone case is in the open state when the top cover is in the open position and in the closed state when the top cover is in the closed position. The lock mechanism includes a lock assembly disposed in the casing and a flick block movably disposed on the top cover. The lock assembly is configured to lock the top cover in the closed position. The flick block is configured to move the lock assembly relative to the casing to make the lock assembly release lock of the top cover.

Abstract: A hinge assembly comprises a first connecting member, a second connecting member, a first shaft, a second shaft, and a clockwork spring. The first connecting member includes a first pivot portion. The second connecting member includes a second pivot portion. The first shaft is pivotally connected to the first pivotal portion of the first connecting member and the second pivotal portion of the second connecting member. The second shaft is configured on the first connecting member and spaced from the first shaft. The clockwork spring includes a first end and a second end away from the first end; the first end fixed to the second shaft rod, the second end fixed to the second connecting member. When the second connecting member pivots with respect to the first connecting member, the arrangement of the clockwork spring can provide a more stable pivoting force for the second connecting member.
