[0001] This application is a divisional application of patent application No. 2023800819265, filed on November 2, 2023, entitled "Electronic Device Including Waterproof Structure," and claims priority thereto. The contents of the aforementioned patent application are incorporated herein by reference. Technical Field

[0002] Various embodiments of this disclosure relate to an electronic device including a waterproof structure. Background Technology

[0003] As the functional differences between electronic devices from different manufacturers significantly narrow, devices are becoming increasingly thinner to meet consumer demand. Simultaneously, the rigidity of electronic devices is increasing, and their design aspects are being strengthened, while improvements are being made to differentiate their functional components. Electronic devices can have deformable structures that allow for convenient portability and the use of large-screen displays when in use. For example, electronic devices can include foldable devices that are rotatably coupled to each other via hinge mechanisms. Foldable electronic devices need to be designed to ensure efficient layout of internal electronic components and reliable operation in response to folding operations. Summary of the Invention

[0004] Technical issues The electronic device may include a foldable electronic device comprising a first housing and a second housing foldably connected to the first housing via a hinge mechanism (e.g., a hinge module, hinge structure, or hinge assembly). The first and second housings are rotatably coupled to each other via the hinge mechanism, thereby ensuring operational reliability in a folded and / or unfolded state. By utilizing the hinge mechanism to rotate the first housing relative to the second housing within a range of 0 to 360 degrees, the foldable electronic device can operate in an inward-folding and / or outward-folding manner. The foldable electronic device may include a flexible display configured to be supported by the first and second housings in a 180-degree open state.

[0005] Foldable electronic devices may include flexible printed circuit boards (FPCBs) electrically connecting a first housing and a second housing. The flexible printed circuit board may be disposed within the internal space of a hinge housing housing housing a hinge mechanism and includes a curved portion formed in a bent shape (e.g., a shape that bends at least once), the curved portion being at least partially elastic (e.g., resilient) to accommodate length deformation according to a folding operation of the foldable electronic device. The flexible printed circuit board may be configured such that one end passes through at least a portion 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 portion of the second housing and is then electrically connected to a second printed circuit board (e.g., a sub-printed circuit board).

[0006] The foldable electronic device may include a fixing structure formed in portions of the device that extend from the curved portion into the first and second housings. For example, the fixing structure may be configured such that a reinforcement disposed on a flexible printed circuit board is attached to at least a portion of the first or second housing. The foldable electronic device may include a waterproof structure for preventing or reducing the ingress of external moisture or foreign matter, provided by a flexible printed circuit board disposed through each housing. This waterproof structure may be configured such that a sealing structure seals through-holes through which the flexible printed circuit board passes through the first and second housings.

[0007] However, as foldable electronics become thinner or the folding methods of flexible displays diversify (e.g., folding into a teardrop shape), the space for accommodating the bent portion of the flexible printed circuit board, from the fixed structure to the internal 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 of the folding region of a flexible display increases, the space required for the bent portion of the flexible printed circuit board also increases, which may make it difficult to make the electronics thinner.

[0008] According to various embodiments of this disclosure, an electronic device may be provided that includes a waterproof structure capable of helping to make the electronic device thinner.

[0009] According to various embodiments, an electronic device with a waterproof structure can be provided, the waterproof structure including a waterproof structure that helps to make the electronic device thinner, while guiding the smooth operation of the electronic device by ensuring space for the elastic deformation of the flexible printed circuit board.

[0010] According to various embodiments, an electronic device may be provided that includes a waterproof structure that can help improve assembly.

[0013] According to various embodiments, the electronic device may include a first housing including at least one first electronic component; a second housing including at least one second electronic component; a hinge mechanism rotatably connecting the first and second housings to each other; a flexible printed circuit board (PCB) passing through through-holes formed in the first and second housings and electrically connecting at least one first electronic component and at least one second electronic component; and waterproof structures, each disposed in one of the through-holes, wherein the waterproof structures may include: a first waterproof member coupled to a reinforcement disposed on the PCB substrate to form an open ring structure; a second waterproof member disposed on the reinforcement and the first waterproof member to cover the opening; a third waterproof member disposed between the first housing and / or the second housing and the reinforcement and the first waterproof member; and a fixing bracket configured to overlap with at least a portion of the second waterproof member and be fixed to the first housing and / or the second housing, wherein the reinforcement and the first waterproof member may be disposed on the first and second housings in such a way that the ring structure surrounds the outer periphery of the through-hole.

In an embodiment, the two ends of the reinforcement 161 may include a pair of coupling grooves 1611 and 1612 recessed from the outer periphery.

[0059] According to various embodiments, the electronic device 100 may include a waterproof structure 200 (e.g., Figure 4The first waterproof structure 200 is provided through a through hole 1131c in the recess 1131d to seal the through hole 1131c through which the flexible printed circuit board 160 passes. In an embodiment, the waterproof structure 200 may include: a first waterproof member 210, which is at least partially coupled to the reinforcement 161; a second waterproof member 220, which is coupled to the first waterproof member 210 and the reinforcement 161; and a fixing bracket 230, which is disposed above the second waterproof member 220 to fix the first waterproof member 210, the second waterproof member 220 and the reinforcement 160 in the recess 1131d. In one embodiment, the fixing bracket 230 may include: a plate portion 231 configured to at least partially overlap the second waterproof member 220; and a pair of extensions 232 and 233 extending from both ends of the plate portion 231 and designed to be fastened with screws S into screw holes 1135 formed in the recess 1131d. In another embodiment, the waterproof structure 200 may include a third waterproof member 240 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.

[0060] 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 both ends of the body 211. In embodiments, for example, the first waterproof member 210 may have a partially open annular shape. In embodiments, the first waterproof member 210 may be formed as... Shape. In embodiments, the body 211 may be formed of a rigid material, and the paired coupling protrusions 212 and 213 coupled to the body 211 may be formed of a flexible soft material. In embodiments, the body 211 may be formed of metal or polycarbonate (PC). In embodiments, the paired coupling protrusions 212 and 213 may be formed of a flexible material such as silicone, rubber, or polyurethane. In embodiments, the body 211 and the paired coupling protrusions 212 and 213 may be coupled by injection molding. In embodiments, the body 211 and the paired coupling protrusions 212 and 213 may be coupled by an attachment method such as adhesive or tape. In embodiments, the body 211 and the paired coupling protrusions 212 and 213 may be coupled by structural shape. In embodiments, the reinforcement 161 may include the paired coupling protrusions 212 and 213. For example, the paired coupling protrusions 212 and 213 coupled to the reinforcement 161 may be formed of a flexible soft material. For example, the reinforcement 161 and the paired coupling protrusions 212 and 213 can be coupled by an attachment method such as adhesive or tape. In some embodiments, the reinforcement 161 and the paired coupling protrusions 212 and 213 can be coupled by structural shape. In some embodiments, the coupling protrusions 212 and 213 can be formed on the reinforcement. In this case, coupling grooves 1611 and 1612 coupled to the coupling protrusions 212 and 213 can be formed on the first waterproof member 210. For example, the coupling groove coupled to the body 211 can also be formed of an elastic material.

[0061] The assembly sequence of the waterproof structure 200 is as follows.

[0062] Reference 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 can be coupled firstly. In an embodiment, the first waterproof member 210 can be coupled by inserting (e.g., press-fitting) pairs of coupling protrusions 212 and 213 into pairs of coupling grooves 1611 and 1612 of the reinforcement 161. In an embodiment, the pairs of coupling protrusions 212 and 213 are formed of a flexible soft material and are therefore tightly coupled in an overlapping manner with the pairs of coupling grooves 1611 and 1612, which helps to maintain the waterproof function. In an embodiment, the open annular shape of the first waterproof member 210 can be transformed into a closed-loop shape by coupling with the reinforcement 161, thereby forming an opening 214. Thus, the flexible printed circuit board 160 can pass through the through-hole 1131c below the opening 214.

[0063] Then, as Figure 6cAs shown, a third waterproofing member 240 can be disposed in the recess 1131d to surround the outer periphery of the through hole 1131c. In an embodiment, the third waterproofing member 240 may include waterproof tape (e.g., double-sided tape) attached to the recess 1131d. In an embodiment, the third waterproofing 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 waterproofing member 240 may be omitted.

[0064] In the second operation 503, such as Figure 6d As shown, the reinforcing member 161 and the first waterproof member 210 coupled to the reinforcing member 161 can be disposed in the recess 1131d. In this case, the reinforcing member 161 and the first waterproof member 210 coupled to the reinforcing member 161 can be disposed on the third waterproof member 240. In an embodiment, the closed ring structure formed by the reinforcing member 161 and the first waterproof member 210 can be configured 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 can overlap with the through hole 1131c. In an embodiment, the opening 214 can be smaller than the through hole 1131c. In some embodiments, the opening 214 can be formed to be substantially the same size as the through hole 1131c. In some embodiments, the opening 214 can be formed to be larger than the through hole 1131c. In one embodiment, once the reinforcement 161 and the first waterproof member 210 coupled to the reinforcement 161 are placed in the recess 1131d, the flexible printed circuit board 160 can pass through the through hole 1131c.

[0065] In the third operation 505, such as Figure 6e As shown, the second waterproof component 220 can be disposed above the reinforcement 161 and the first waterproof component 210 in a manner that covers the opening 214. In one embodiment, the second waterproof component 220 may include waterproof tape. In another embodiment, the second waterproof component 220 may include double-sided tape.

[0066] In the fourth operation 507, such 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 extensions 232 and 233 at both ends are securely 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 configured to overlap with the opening 214. Therefore, the opening 214 of the through hole 1131c can be sealed and covered by the second waterproof member 220 and the third waterproof member 240. Furthermore, the first waterproof member 210, the second waterproof member 220, the third waterproof member 240, and the reinforcing member 161 can be securely 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 may be configured to align with the second surface 1131b of the first support member 1131, or to be set to be lower than the second surface 1131b within the recess 1131d.
