CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is a U.S. National Stage application under 35 U.S.C. § 371 of an International application number PCT/KR2018/013527, filed on Nov. 8, 2018, which is based on and claimed priority of a Korean patent application number 10-2017-0150578, filed on Nov. 13, 2017, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.

TECHNICAL FIELD

Various embodiments of the present disclosure relate to an electronic device having a waterproof structure.

BACKGROUND ART

With the development of digital technologies, electronic devices are provided in various forms, such as a smart phone, a tablet Personal Computer (PC), a Personal Digital Assistant (PDA), or the like. The electronic device is also developed such that it is worn by a user to improve portability and user accessibility.

An exterior of the electronic device may be constructed due to bonding of a metallic outer member and a non-metallic member. The electronic device including the metallic outer member may provide a metal-specific luxurious design. Since a metallic material included in the metallic outer member also has effect on durability, the electronic device to which the metallic outer member is applied is becoming more popular.

DISCLOSURE OF INVENTION

Technical Problem

The metallic outer member may be constructed of a metallic material having a property capable of being stably joined to a non-metallic member such as resin. When the metallic outer member and the non-metallic member are stably joined, an interface between the metallic outer member and the non-metallic member may not be separated by an impact caused by a drop or the like but be capable of withstanding it. However, when the metallic outer member is constructed of a metallic material having a corrosion resistance property and an aesthetic property in design, it may be difficult to secure stable joining force (or bonding force) between the metallic outer member and the non-metallic member due to a material property thereof. When the interface between the metallic outer member and the non-metallic member is separated, a foreign matter such as water or the like may be introduced into the electronic device through a gap between the metallic outer member and the non-metallic member.

Various embodiments of the present disclosure may provide an electronic device having a waterproof structure for ensuring waterproof performance when it is difficult to stably join a metallic outer member and a non-metallic member.

Solution to Problem

According to an embodiment of the present disclosure, an electronic device may include a front plate, a back plate facing a direction opposite to the front plate, a side member surrounding a space between the front plate and the back plate, constructed integrally with respect to the back plate, or bonded to the back plate, wherein the side member includes an outer structure constructed of a first metallic material and including at least one first surface constructing an outer surface of the side member and at least one second surface facing the space, an inner structure constructed of a second metallic material different from the first metallic material and including at least one third surface at least partially in contact with the second surface and at least one fourth surface facing the space, a touch screen display exposed through the front plate, an internal structure disposed to the space so as to be adjacent to the side member, constructed of a first polymer material, and including at least one fifth surface at least partially in contact with the second surface, a wireless communication circuit electrically coupled with a portion of the inner structure, and a sealant disposed between the fourth surface and at least one sixth surface of the internal structure.

According to an embodiment of the present disclosure, an electronic device may include a front plate, a back plate facing a direction opposite to the front plate, an outer structure surrounding a space between the front plate and the back plate, and including a plurality of first gaps and a plurality of portions physically separated by the first gaps, an inner structure disposed to the space according to the outer structure, and including second gaps aligned with the first gaps and a plurality of portions physically separated by the second gaps, a non-metallic internal structure bonded with the inner structure in the space, and including the first gaps and a portion disposed to the second gaps to constitute an outer surface of the electronic device, an organic adhesive layer disposed between the inner structure and the internal structure, and a display disposed to the space and exposed through the front plate. The outer structure and the inner structure may be constructed of different metallic materials.

Advantageous Effects of Invention

According to various embodiments of the present disclosure, a metallic outer member is allowed to include an outer structure of a first metallic material and an inner structure of a second metallic material different from the first metallic material, and is designed to have bonding force between the inner structure and an internal structure of a non-metal material, thereby ensuring waterproof performance.
