Claims (15)

  1. An electronic device (200) comprising: a first housing (220, 520); a decoration part (210, 510) disposed to be at least partially spaced apart from the first housing; a second housing (250, 540); a housing bonding member (240, 530) extending along a periphery of the second housing and having one surface on which the first housing and the decoration part are disposed, and the other surface on which the second housing is disposed; a plate (410) disposed on at least a portion of the first housing and the decoration part, the plate comprising a flat surface area (412) and a protruding area (411) protruding from the flat surface area to be disposed in a space between the first housing and the decoration part; and a waterproof member (430) disposed along the protruding area and configured to seal at least a part of the space.
  2. The electronic device of claim 1, wherein the plate extends in a longitudinal direction of the electronic device, is bent at least partially, and then extends in a width direction of the electronic device.
  3. The electronic device of claim 2, wherein the flat surface area of the plate comprises a flat surface bent area (4121) that extends in the longitudinal direction of the electronic device, is bent at least partially, and extends in the width direction of the electronic device, and wherein at least a part of the flat surface bent area is formed as a curved surface.
  4. The electronic device of claim 1, further comprising a bonding member (420, 420-1, 420-2) disposed in at least a part of the flat surface area and configured to bond at least a part of the plate to the decoration part and the first housing.
  5. The electronic device of claim 1, further comprising two bonding members, one bonding member of the two bonding members being disposed along the flat surface area extending to one side of the protruding area, and the remaining bonding member being disposed along the flat surface area extending to the other side of the protruding area.
  6. The electronic device of claim 4, wherein a thickness of the bonding member is smaller than a thickness of the housing bonding member.
  7. The electronic device of claim 1, wherein at least a portion of the first housing comprises an installation area (221) in which the decoration part is disposed, and the plate extends to correspond to a periphery of the installation area of the first housing.
  8. The electronic device of claim 1, wherein a thickness of the flat surface area of the plate is 0.05 mm to 0.3 mm.
  9. The electronic device of claim 1, wherein the protruding area of the plate is formed as at least a part of the plate is bent in a height direction of the electronic device.
  10. The electronic device of claim 1, wherein the decoration part comprises a decoration part extension area (512) formed as at least a part of the decoration part extends in one direction of the decoration part, and wherein the decoration part extension area is positioned to be spaced apart from the protruding area of the plate and at least a part of the first housing in a height direction of the electronic device.
  11. The electronic device of claim 10, wherein the waterproof member is in contact with the decoration part at one side and is in contact with the first housing at the other side.
  12. The electronic device of claim 1, wherein the protruding area of the plate comprises a protruding extension area (4112) further extending in a longitudinal direction of the plate than a distal end of the flat surface area of the plate.
  13. The electronic device of claim 12, wherein the waterproof member comprises a waterproof extension area (432) disposed along the protruding extension area.
  14. The electronic device of claim 13, wherein the waterproof member is disposed to overlap at least a part of the housing bonding member in one area of the waterproof member that further extends in the longitudinal direction of the plate than the flat surface area.
  15. The electronic device of claim 1, wherein at least a part of the waterproof member is disposed to surround the protruding area and cover at least a part of the flat surface area.

Description

[Technical Field] The present disclosure relates to a waterproof structure and an electronic device including the same. [Background Art] An electronic device may include a back glass and a decoration part (cam deco). At least a part of the back glass and at least a part of the decoration part may be formed in shapes corresponding to each other and disposed to be spaced apart from each other at a predetermined interval. The electronic device may include a waterproof tape having one surface on which the back glass and the decoration part are at least partially disposed. The waterproof tape may serve to ensure waterproof performance of the electronic device. The back glass and the decoration part may be at least partially disposed on one surface of the waterproof tape, and a stainless steel (STS) plate may be disposed on the other surface of the waterproof tape. The stainless steel plate may be a reinforcement structure for stably bonding the waterproof tape. KR 20220043665 discloses a mobile terminal having a waterproof function. The terminal comprises a first housing, a second housing and a decoration part spaced apart from the first housing. [Disclosure of Invention] [Technical Problem] A waterproof structure of an electronic device, which uses a waterproof tape and a stainless plate, may require an arrangement space larger than a predetermined reference arrangement space. For example, an arrangement space of about 0.6 mm may be required in a direction from one surface of a decoration part and one surface of a back glass toward the inside of the electronic device. In addition, the waterproof structure of the electronic device, which uses the waterproof tape and the stainless plate, includes the stainless plate having a predetermined thickness, which may increase a weight and material costs of the electronic device. An electronic device according to an embodiment of the present disclosure may provide a waterproof structure of the electronic device capable of ensuring an arrangement space and reducing a weight and material costs. [Solution to Problem] The invention is defined in the appended claims. [Advantageous Effects of Invention] The electronic device including the waterproof structure according to the embodiment of the present disclosure may increase the arrangement space for the electronic device by reducing the thickness of the bonding member. The electronic device including the waterproof structure according to the embodiment of the present disclosure may reduce the weight and material costs of the waterproof structure by reducing the thickness and volume of the stainless plate.
