[0042] Embodiment!

[0043] As shown in FIGS. 2 to 8, the present disclosure provides a foldable sofa armrest, including an armrest frame and armrest skin 12. The armrest skin 12 covers an outer surface of the armrest frame. The armrest frame includes first frame 1, second frame 2, and a folding part. The folding part includes first folding member 3, second folding member 4, and a connecting component. The first folding member 3 is provided on the first frame 1, and the second folding member 4 is provided on the second frame 2. The armrest frame presents a first state and a second state and can be switched between said first state and second state. In the first state, the connecting component securely connects the first folding member 3 to the second folding member 4. In the second state, the first folding member 3 and the second folding member 4 are rotatable relative to each other.

[0044] In the first state, the connecting component securely connects the first folding member 3 to the second folding member 4, and the folding part unfolds the first frame 1 and the second frame 2, such that the sofa armrest is in an unfolded state. In the second state, the first folding member 3 and the second folding member 4 are rotatable relative to each other, and the relative positions of the first frame 1 and the second frame 2 are not fixed, making the sofa armrest in a foldable state. In the present disclosure, during use, the sofa armrest can be in an unfolded state and can be used normally. Besides, the sofa armrest is in a foldable state during transportation or storage, reducing space occupation, facilitating transportation and storage, and reducing transportation and storage costs.

[0045] Specifically, as shown in FIGS. 3 and 4, the connecting component includes a rotating connector and a fastener. In the first state, the rotating connector connects the first folding member 3 to the second folding member 4, and the fastener fixes the first folding member 3 to the second folding member 4. In the second state, the rotating connector rotatably connects the first folding member 3 to the second folding member 4. In the first state, the first foldable member 3 and the second foldable member 4 are connected through a rotating shaft, forming a connection point between the first foldable member 3 and the second foldable member 4. The first folding member 3 and the second folding member 4 are fixed through the fastener, forming another connection point between the first folding member 3 and the second folding member 4. The two connection points and the fastener work together to support the first frame 1 and the second frame 2, causing the sofa armrest to be in an unfolded state. In the second state, the first folding member 3 and the second folding member 4 are connected through the rotating shaft. There is only one connection point between the first folding member 3 and the second folding member 4.
