Integrated fastening structure and electronic device including the same

An electronic device comprising:

• a first structure comprising a first fastening structure;
• a second structure disposed on an upper portion of the first structure and comprising a second fastening structure;
• a third structure disposed on an upper portion of the second structure and comprising a third fastening structure;
• and
• an integrated fastening structure comprising a first engagement portion and a second engagement portion, the integrated fastening structure being configured to directly connect the first structure, the second structure, and the third structure,
• wherein each of the first engagement portion and the second engagement portion is configured to engage a different fastening structure among the first fastening structure, the second fastening structure, and the third fastening structure,
• wherein the integrated fastening structure further comprises a shaft extending between (i) a lower end of the shaft positioned on a lower portion of the first structure that is opposite to the upper portion of the first structure and (ii) an upper end of the shaft positioned on an upper portion of the third structure,
• wherein the first engagement portion is disposed proximal to the lower end of the shaft, and the second engagement portion is disposed at a predetermined position between the upper end of the shaft and the lower end of the shaft, and
• wherein the integrated fastening structure further comprises:
• a stopper portion disposed proximal to the upper end of the shaft;
• and
• at least one elastic member disposed to surround the shaft in at least one of a space between the first engagement portion and the second engagement portion or a space between the second engagement portion and the stopper portion.

An integrated fastening structure configured to directly connect a plurality of structures of an electronic device, the integrated fastening structure comprising:

• a shaft extending between an upper end of the shaft and a lower end of the shaft;
• a first engagement portion provided at the lower end of the shaft, the first engagement portion comprising a pair of first engagement protrusions extending in a first direction toward the upper end or the lower end of the shaft from two opposite sides and inclined away from the shaft, the pair of first engagement protrusions configured to be elastically deformable in a direction towards the shaft in response to an external force applied in a direction perpendicular to an axis of the shaft;
• and
• a second engagement portion provided at the upper end of the shaft or at a predetermined position between the upper end of the shaft and the lower end of the shaft, the second engagement portion comprising a pair of second engagement protrusions extending in a second direction toward the upper end or the lower end of the shaft from two opposite sides and inclined away from the shaft, the pair of second engagement protrusions configured to be elastically deformable in the direction towards the shaft in response to the external force applied in the direction perpendicular to the axis of the shaft,
• wherein at least one of the first engagement portion or the second engagement portion comprises:
• a pair of enforcement protrusions extending toward an end of the shaft opposite to the first direction or the second direction, respectively, from two opposite sides and inclined away from the shaft, the pair of enforcement protrusions being configured to connect to a pair of engagement protrusions of the at least one of the first engagement portion or the second engagement portion.
