Technical Field
[0001] Various embodiments of the present disclosure relate to an electronic device including a waterproof structure. Background Art
[0002] As the functional gap between electronic devices of different manufacturers has significantly narrowed, electronic devices are gradually becoming thinner to meet the purchase needs of consumers. At the same time, the rigidity of electronic devices is increasing, and their design aspects are being strengthened, while improvements are being made to distinguish their functional elements. Electronic devices may have a deformable structure that allows for convenient portability and the ability to use a large screen display when in use. For example, an electronic device may include a foldable electronic device rotatably coupled to each other through a hinge device. The foldable electronic device needs to be designed to ensure an effective layout of internal electronic components and to ensure operational reliability in response to a folding operation. Summary of the Invention
[0003] Technical Problem An electronic device may include a foldable electronic device including a first housing and a second housing foldably connected to the first housing through a hinge device (e.g., a hinge module, a hinge structure, or a hinge assembly). The first housing and the second housing are rotatably coupled to each other through the hinge device to ensure operational reliability in a folded state and / or an unfolded state. By rotating the first housing relative to the second housing within a range of 0 degrees to 360 degrees using the hinge device, the foldable electronic device may be operated in an in-folded manner and / or an out-folded manner. The foldable electronic device may include a flexible display disposed to be supported by the first housing and the second housing in a state opened at 180 degrees.
[0004] The foldable electronic device may include a flexible printed circuit board (FPCB) electrically connecting the first housing and the second housing. The flexible printed circuit board may be disposed in an internal space of a hinge housing accommodating the hinge device and include a bent portion formed in a bent shape (e.g., a shape bent at least once), the bent portion being at least partially elastic (e.g., having resilience) to accommodate a length deformed according to a folding operation of the foldable electronic device. The flexible printed circuit board may be disposed such that one end passes through at least a part of the first housing and is then electrically connected to a first printed circuit board (e.g., a main printed circuit board), and the other end passes through at least a part of the second housing and is then electrically connected to a second printed circuit board (e.g., a sub printed circuit board).
[0005] The foldable electronic device may include a fixing structure formed in a portion where the first housing and the second housing are introduced from a bending portion. For example, the fixing structure may be configured such that a reinforcing member provided on a flexible printed circuit board is attached to at least a part of the first housing or the second housing. The foldable electronic device may include a waterproof structure for preventing or reducing the entry of external moisture or foreign substances, and the waterproof structure is provided by a flexible printed circuit board disposed to penetrate each housing. Such a waterproof structure may be configured such that the sealing structure seals a through-hole through which the flexible printed circuit board passes through the first housing and the second housing.
[0006] However, as the foldable electronic device becomes thinner or the folding method of the flexible display becomes diversified (e.g., folded into a droplet shape), the space for accommodating the bent portion of the flexible printed circuit board from the fixing structure to the inner space of the hinge housing (e.g., the space required for elastic deformation of the bending region) may become narrower. For example, as the space in the folding region of the flexible display increases, the space required for the bent portion of the flexible printed circuit board also increases, which may make it difficult for the electronic device to be thinner.
[0007] According to various embodiments of the present disclosure, an electronic device may be provided that includes a waterproof structure capable of helping to make the electronic device thinner.

In an embodiment, the waterproof structure 200 may include a third waterproof member 240 that is applied to the recess 1131d along the periphery of the through-hole 1131c before the reinforcement 161 and the first waterproof member 210 are disposed in the recess 1131d.

[0059] According to various embodiments, the first waterproof member 210 may include a body 211 and a pair of coupling protrusions 212 and 213 formed at opposite ends of the body 211. In an embodiment, for example, the first waterproof member 210 may have a partially open annular shape. In an embodiment, the first waterproof member 210 may be formed as Shape.

In an embodiment, the body 211 may be formed of metal or polycarbonate (PC). In an embodiment, the pair of coupling protrusions 212 and 213 may be formed of an elastic material such as silicone resin, rubber, or polyurethane.

For example, the pair of coupling protrusions 212 and 213 coupled to the reinforcement 161 may be formed of an elastic soft material. For example, the reinforcement 161 and the pair of coupling protrusions 212 and 213 may be coupled by an attachment method such as adhesion or tape sticking. In some embodiments, the reinforcement 161 and the pair of coupling protrusions 212 and 213 may be coupled by a structural shape. In some embodiments, the coupling protrusions 212 and 213 may be formed on the reinforcement. In this case, the coupling grooves 1611 and 1612 coupled to the coupling protrusions 212 and 213 may be formed on the first waterproof member 210. For example, the coupling grooves coupled to the body 211 may also be formed of an elastic material.
[0060] Hereinafter, the assembly sequence of the waterproof structure 200 is as follows.
[0061] Refer to Figures 5b to 6g , in the first operation 501, before applying the waterproof structure 200 to the electronic device 100, the reinforcement 161 of the flexible printed circuit board 160 and the first waterproof member 210 may be first coupled. In an embodiment, the first waterproof member 210 may be coupled in such a way that the pair of coupling protrusions 212 and 213 are inserted (e.g., press-fitted) into the pair of coupling grooves 1611 and 1612 of the reinforcement 161. In an embodiment, the pair of coupling protrusions 212 and 213 are formed of an elastic soft material, and thus are tightly coupled in an overlapping manner with the pair of coupling grooves 1611 and 1612, which helps to maintain the waterproof function. In an embodiment, the open ring shape of the first waterproof member 210 may be transformed into a closed-loop shape by coupling with the reinforcement 161, thereby forming an opening 214. Accordingly, the flexible printed circuit board 160 may pass through the through hole 1131c below the opening 214.
[0062] Then, as Figure 6cAs shown, the third waterproof member 240 may be disposed in the recess 1131d to surround the outer periphery of the through hole 1131c. In an embodiment, the third waterproof member 240 may include a waterproof tape (e.g., double-sided tape) attached to the recess 1131d. In an embodiment, the third waterproof member 240 may be attached to the entire area of the recess 1131d except for the through hole 1131c and the screw fastening hole 1135. In some embodiments, the third waterproof member 240 may be omitted.
[0063] In the second operation 503, as Figure 6d shown, the reinforcement member 161 and the first waterproof member 210 coupled to the reinforcement member 161 may be disposed in the recess 1131d. In this case, the reinforcement member 161 and the first waterproof member 210 coupled to the reinforcement member 161 may be disposed above the third waterproof member 240. In an embodiment, the closed ring structure formed by the reinforcement member 161 and the first waterproof member 210 may be set to contact along the outer periphery of the through hole 1131c. For example, when the first waterproof member 210 is viewed from above, or when the second surface 1131b is viewed from above, the opening 214 may overlap with the through hole 1131c. In an embodiment, the opening 214 may be smaller than the through hole 1131c. In some embodiments, the opening 214 may be formed to have substantially the same size as the through hole 1131c. In some embodiments, the opening 214 may be formed to be larger than the through hole 1131c. In an embodiment, once the reinforcement member 161 and the first waterproof member 210 coupled to the reinforcement member 161 are disposed in the recess 1131d, the flexible printed circuit board 160 may pass through the through hole 1131c.
[0064] In the third operation 505, as Figure 6e shown, the second waterproof member 220 may be disposed above the reinforcement member 161 and the first waterproof member 210 so as to cover the opening 214. In an embodiment, the second waterproof member 220 may include a waterproof tape. In an embodiment, the second waterproof member 220 may include a double-sided tape.
[0065] In the fourth operation 507, as Figure 6f and 6gAs shown, the fixing bracket 230 can be fixed in the following manner: the plate portion 231 is disposed above the second waterproof member 220, and the extending portions 232 and 233 at both ends are firmly fastened to the screw fastening holes 1135 formed in the recess 1131d using screws S. In an embodiment, the plate portion 231 of the fixing bracket 230 can be formed to at least cover the opening 214 when the first waterproof member 210 is viewed from above, and can be arranged to overlap with the opening 214. Thus, the opening 214 covering the through hole 1131c can be sealed by the second waterproof member 220 and the third waterproof member 240. In addition, the first waterproof member 210, the second waterproof member 220, the third waterproof member 240, and the reinforcing member 161 can be firmly fixed in the recess 1131d of the first housing 110 by the fixing bracket 230. In an embodiment, after the waterproof structure 200 is fully assembled, the plate portion 231 of the fixing bracket 230 can be configured to align with the second surface 1131b of the first support member 1131, or can be arranged to be lower than the second surface 1131b within the recess 1131d.
