Abstract: A housing device includes a first housing body. The first housing body includes a first housing seat and a first combination structure. The first housing seat has a first bottom surface, a first wall and an extension wall. The first wall and the extension wall are respectively extended from the first bottom surface in a direction away from the first bottom surface, and the extension wall is located at an inner side of the first wall and higher than the first wall. The first combination structure includes a hook, a base and a first bump provided as an energy director. The hook is disposed at a side of the extension wall facing the first wall. The base is protruded from the first wall and located below the hook correspondingly, and the first bump is disposed on the base.

Abstract: A butting structure includes a first connecting portion disposed on the inner surface of a first object and a second connecting portion disposed on the inner surface of a second object. A leading angle is provided at the junction of a top surface and a first side of the first connecting portion. An accommodation space is defined between the top surface and the inner surface of the first object. The second connecting portion includes a bump and a horn structure. The bump is connected to the second object and is disposed corresponding to the accommodation space. The horn structure is connected to the second object and is disposed corresponding to the first connecting portion. A first gap is provided between the bump and the horn structure. An assembling method of the butting structure is also provided.

Abstract: A connecting structure includes a first connecting portion and a second connecting portion. The first connecting portion includes a first board and a second board. The first board includes a first body, an extension board and a main rib. The first body extends toward a second object. The extension board is disposed on the first body. The main rib is connected to a first object and disposed along the first body and the extension board. The second board connects to the first object, the first body, and the extension board. The second connecting portion includes a base connecting to the second object and a non-closed columnar body connecting to the base. The non-closed columnar body includes a blocking wall extending toward the first object and a bottom board disposed on the blocking wall. The blocking wall and the bottom board form an accommodating space corresponding to the extension board.
