Description

Technical Field

[0001] Various embodiments of the present disclosure are directed to an electronic device including a flexible printed circuit board. Background Art

[0002] As the functional gap between different manufacturers has been significantly reduced, electronic devices are becoming increasingly slimmer to meet consumer demands, and improvements are being made to increase rigidity, enhance design aspects, and differentiate functional elements. These electronic devices are evolving from a uniform rectangular shape to a variety of shapes. For example, an electronic device may have a deformable structure that is easy to carry and provide access to a large screen display when in use. As part of these electronic devices, foldable type electronic devices may be included. As foldable electronic devices become thinner, it may be necessary to design an efficient layout of internal electronic components and ensure their operational reliability. Summary of the invention

[0003] Technical issues

[0004] The electronic device may include a foldable electronic device, which includes a first shell, a second shell foldably connected to the first shell by a hinge device (e.g., a hinge module, a hinge or a hinge assembly). The first shell and the second shell are structurally connected to the hinge device, so that the operational reliability of the folded and / or unfolded state can be ensured. The foldable electronic device can be operated in an inner folding manner and / or an outer folding manner by rotating the first shell relative to the second shell in a range of 0 to 360 degrees by the hinge device. When the foldable electronic device is opened to 180 degrees, the foldable electronic device may include a flexible display arranged across the first shell and the second shell.

[0005] In order to meet the trend of increasingly slim foldable electronic devices, it may be necessary to improve the layout design of electronic components disposed in the internal space of the foldable electronic device. The foldable electronic device may include a flexible printed circuit board (FPCB) that electrically connects a first housing and a second housing to each other. The flexible printed circuit board may be formed into an at least partially elastic (e.g., resilient) curved shape (e.g., bendable to bend more than once) to accommodate the deformation length of the flexible printed circuit board according to the folding movement in the internal space of the hinge housing that accommodates the hinge device.

[0006] However, as electronic devices become slimmer (eg, thinner), the space available to accommodate the bent portion of the flexible printed circuit board becomes smaller, resulting in a smaller curvature, and stress concentration from frequent folding motions may cause fractures.

[0007] The electronic device may further include a waterproof structure for the flexible printed circuit board, which connects the two housings across the hinge device. The aforementioned waterproof structure may be deformed or misaligned because the flexible printed circuit board moves with frequent folding movements, thereby reducing the waterproof function.

[0008] Various embodiments of the present disclosure may provide an electronic device including a layout design of electronic components for slimming.

[0009] Various embodiments may provide an electronic device including a sliding structure for a flexible printed circuit board, which may contribute to operational reliability when the electronic device is slimmed down.

[0010] Various embodiments may provide an electronic device including a flexible printed circuit board, which provides a reliable waterproof function even in the case of frequent folding movements.

The rear surface may be exposed to the internal area of ​​the electronic device 100, such as to the first space 1101. In one embodiment, when the first rear cover 114 is viewed from above (for example, in a plan view or a view along the thickness direction), the second display 131 may overlap with a portion of the second battery B2.

[0120] Figure 7a is a diagram showing various embodiments according to the present disclosure. Figure 1b A partial cross-sectional view of the electronic device viewed along line 7a-7a in FIG. Figure 7b is a perspective view schematically illustrating a connection relationship between a second printed circuit board and a flexible printed circuit board according to various embodiments of the present disclosure. Figure 7c and Figure 7d 2 is a view schematically illustrating the position of a flexible printed circuit board in an unfolded state and a folded state of an electronic device according to various embodiments of the present disclosure.

[0121] refer to Figures 7a to 7d The electronic device 100 may include a first housing 110, a hinge device (eg, Figure 1b The electronic device 100 may include a second housing 120 foldably connected to the first housing 110 and a first display 130 supported by the first housing 110 and the second housing 120. Figure 3 The first space (eg, Figure 3 A first printed circuit board (eg, Figure 31101) and a second printed circuit board 152 disposed in the second space 1201 of the second housing 120. In an embodiment, the electronic device 100 may include a flexible printed circuit board 160, such that one end (e.g., the first end or the distal end) of the flexible printed circuit board 160 is electrically connected to the first printed circuit board 151 in the first space 1101, and the other end (e.g., the second end opposite to the first end) of the flexible printed circuit board 160 is electrically connected to the second printed circuit board 152 in the second space 1201 across the hinge device 140. That is, the flexible printed circuit board 160 is electrically connected to the corresponding circuit board at the corresponding end of the flexible printed circuit board 160.

[0122] In an embodiment, the flexible printed circuit board 160 may be configured to have a shape that is bent at least once in the internal space of the hinge housing 141 for accommodating the hinge device 140, so that the flexible printed circuit board 160 may have a movable and / or bendable free length to accommodate a length change in response to a folding motion of the electronic device 100. For example, the flexible printed circuit board 160 may include a first bending portion R1 bent in one direction (e.g., -y-axis direction) and a second bending portion R2 bent in a direction opposite to the first bending portion R1 (e.g., in the y-axis direction), with an inflection point between the first bending portion R1 and the second bending portion R2. The flexible printed circuit board 160 may be elastically bent to be in a curved shape, and is resilient to accommodate a length change caused by the folding motion of the electronic device 100. That is, the length of the flexible printed circuit board 160 along the y-axis direction may increase or decrease.

[0124] According to various embodiments of the present disclosure, by being accommodated in a space that shrinks or decreases in volume as the electronic device 100 is slimmed down in the thickness direction (e.g., a space that reduces the thickness of the electronic device 100), the first curved portion R1 and / or the second curved portion R2 of the flexible printed circuit board 160 may have a small curvature and be subjected to stress concentration and eventual fracture due to frequent folding movements. In order to solve these problems, one or more embodiments include the flexible printed circuit board 160, which is provided with a sliding structure (e.g., Figure 8aThe sliding structure 200 in the electronic device 100 is slidably disposed in the inner space 1201 of the second housing 120 with the terminal portion 161 in the longitudinal direction of the electronic device 100 (for example, in the ±y-axis direction as the sliding direction). In one embodiment, the terminal portion 161 of the flexible printed circuit board 160 is slidably disposed in the inner space 1201 of the second housing 120 through a sliding bracket (for example, Figure 8a The sliding bracket 210 in the figure holds the connector 1521 connected to the second printed circuit board 152 and is slidable in the longitudinal direction of the electronic device 100 (for example, in the ±y-axis direction), thereby flexibly changing the curvature of the first curved portion R1 and / or the second curved portion R2, thereby reducing the occurrence of breakage.

[0125] refer to Figure 7a For example, the terminal portion 161 of the flexible printed circuit board 160 may be movable so as to be movable in a first direction (in the ① direction) (for example, in the direction of the hinge device) along the sliding direction to provide the electronic device 100 in a folded state while maintaining an electrical connection with the connector 1521 of the second printed circuit board 152. That is, the folded electronic device 100 may include the flexible printed circuit board 160 electrically connected to the second printed circuit board 152 moving toward the first printed circuit board 151 along the sliding direction. Reference Figure 7b , the terminal portion 161 of the flexible printed circuit board 160 may be movable so as to move in a second direction (② direction) opposite to the first direction (e.g., in a direction away from the hinge device) to provide the electronic device 100 in an unfolded state. That is, the unfolded electronic device 100 may include the flexible printed circuit board 160 electrically connected to the second printed circuit board 152 moving in a direction away from the first printed circuit board 151 along the sliding direction.

[0126] In some embodiments, depending on the shapes of the first curved portion R1 and the second curved portion R2, the terminal portion 161 of the flexible printed circuit board can be implemented to move in the second direction (in the ② direction) when the electronic device is in a folded state, and to move in the first direction (in the ① direction) when the electronic device is in an unfolded state. For example, the terminal portion 161 of the flexible printed circuit board 160 slides in response to the folding movement of the electronic device 100, thereby minimizing the curvature change of the first curved portion R1 and / or the second curved portion R2 and reducing excessive stress concentration. In some embodiments, the second terminal portion of the flexible printed circuit board 160 (where the flexible printed circuit board 160 is connected to the first printed circuit board 151) may also have a configuration substantially the same as that of the above-described terminal portion 161.

[0127] refer to Figure 7cThe unfolded electronic device 100 has a bent portion of the flexible printed circuit board 160 adjacent to the connector 1521 at a first side of the connector 1521 (at Figure 7c 152), and the length of the terminal portion 161 at the second side of the connector 1521. The folding of the electronic device 100 (e.g., from Figure 7c to Figure 7d The configuration includes sliding the flexible printed circuit board 160 in the ① direction to unfold the bent portion and setting the portion of the flexible printed circuit board 160 adjacent to the connector 1521 at the first side of the connector 1521 to be flat (at Figure 7d 1521), and an increased length of the terminal portion 161 at the second side of the connector 1521. The terminal portion 161 extends further than the connector 1521 at the second side of the connector 1521 to define an extended portion of the terminal portion 161.

[0128] refer to Figure 7a and Figure 8a , the terminal portion 161 may be a pad or protrusion of the flexible printed circuit board 160 protruding from its body, which may be connected to other components or layers within the body of the flexible printed circuit board 160, at which the flexible printed circuit board 160 is electrically connected to a connected or corresponding circuit board. The terminal portion 161 may also refer to the length of the flexible printed circuit board 160 including the pad or protrusion.

In some embodiments, any one of the two sliding structures 200 and 200-1 may be omitted.

[0132] refer to Figures 8a to 8d The electronic device 100 may include a first housing 110, a hinge device (eg, Figure 1b The electronic device 100 may include a second housing 120 foldably connected to the first housing 110 and a first display 130 supported by the first housing 110 and the second housing 120.

In one embodiment, the electronic device 100 may include a flexible printed circuit board 160, such that one end of the flexible printed circuit board 160 is electrically connected to the first printed circuit board 151 in the first space 1101, and the other end of the flexible printed circuit board 160 is electrically connected to the second printed circuit board 152 in the second space 1201 across the hinge device 140.

[0133] According to various embodiments, the electronic device 100 may include a sliding structure 200 to slidably guide the terminal portion 161 of the flexible printed circuit board 160 in the second space 1201. In one embodiment, the sliding structure 200 may include a sliding bracket 210 slidably coupled by a second supporting member 1231 in the second space 1201 of the second housing 120. In one embodiment, the sliding bracket 210 may include a printed circuit board fixing portion 211, to which the terminal portion 161 of the flexible printed circuit board 160 is attached by an adhesive member T1 (e.g., a double-sided tape), and a first extension portion 212 and a second extension portion 213, which extend to define both ends of the printed circuit board fixing portion 211 and include long holes 2121 and 2131, respectively.

[0134] In one embodiment, the first extension portion 212 and the second extension portion 213 may be coupled to the boss 1232 through the washer members W1 and W2, respectively, and the boss 1232 protrudes into the second space 1201 through the second support member 1231. In one embodiment, the sliding bracket 210 may be slidably disposed in the first direction (① direction) or the second direction (② direction) by being coupled to the second housing 120 in such a manner that the screw S passes through the washer members W1 and W2 and the long holes 2121 and 2131 of the first extension portion 212 and the second extension portion 213 and is then fastened to the boss 1232. The long holes 2121 and 2131 may be extended to have a larger size along the sliding direction (e.g., ① direction or ② direction).

[0135] According to various embodiments, the electronic device 100 may include a guide pin 220 and a spring 230, the guide pin 220 being fixed in a pin fixing groove 1233 formed in a side wall 1233a provided by changing the shape of the second support member 1231 of the second housing 120, and the spring 230 being coupled to the guide pin 220 in a manner that the guide pin 220 passes therethrough. In one embodiment, the spring 230 is provided so that one end thereof is supported by the side wall 1233a, and the other end thereof is supported by spring support portions 2122 and 2132 extending from the first extension portion 212 and the second extension portion 213, respectively, thereby allowing the sliding bracket 210 to always remain pressurized or biased in the second direction (② direction). Therefore, the sliding bracket 210 together with the terminal portion 161 of the flexible printed circuit board 160 fixed to the printed circuit board fixing portion 211 can move together in the second direction (② direction) while being pressurized or biased by the spring 230, or can move together in the first direction (① direction) while compressing the spring. In some embodiments, the pressing structure of the sliding bracket 210 by the spring 230 may be omitted. In one embodiment, at least a portion of the guide pin 220 is received in the pin fixing groove 1233 in a manner of penetrating through holes 2122a, 2123a formed at the spring supporting portions 2122 and 2132.

[0136] Figure 9a and Figure 9b 1 is a view showing the position of the flexible printed circuit board when the electronic device is in a folded state according to various embodiments of the present disclosure. The terminal portion 161 of the flexible printed circuit board 160 may be attached to the printed circuit board fixing portion 211 of the sliding bracket 210 by an adhesive member T1 (eg, double-sided tape).

[0137] refer to Figure 9a and Figure 9b, when the electronic device 100 is in the folded state, the terminal portion 161 of the flexible printed circuit board 160 may have moved in the first direction together with (or together with) the sliding bracket 210. In this case, the spring 230 is compressed and pressurizes the sliding bracket 210 in the second direction (② direction). In one embodiment, the curved portions R1 and R2 of the flexible printed circuit board 160 may be formed so that when the electronic device 100 is in the folded state, the curvature of the curved portions R1 and R2 is determined or limited. Therefore, in the folded state of the electronic device 100, the curved portions R1 and R2 can be maintained in a state where they are not overly stressed.

[0138] Fig.10a and Fig.10b is a view illustrating a position of a flexible printed circuit board when an electronic device is in an unfolded state according to various embodiments of the present disclosure.

[0139] refer to Fig.10a and Fig.10b , in the electronic device 100 from ( Figure 9a and Figure 9b In the case where the folded state is transformed to the unfolded state, the bent portions R1 and R2 of the flexible printed circuit board 160 may experience a phenomenon in which the curvature gradually becomes smaller, and stress is concentrated in a limited accommodation space.

[0140] In this case, according to an embodiment of the present disclosure, the terminal portion 161 of the flexible printed circuit board 160 can be moved in the second direction (② direction) by utilizing the restoring force or bias of the spring 230 in the ② direction in combination with the movement of the sliding bracket 210, and the curvature change of the curved portions R1 and R2 can be reduced, thereby reducing stress concentration. Therefore, even when the flexible printed circuit board 160 is in the unfolded state of the electronic device 100, the sliding structure 200 can help reduce the possibility of the flexible printed circuit board 160 breaking by reducing the stress concentration at the curved portions R1 and R2. In some embodiments, when the spring support structure is omitted, the terminal portion 1610 of the flexible printed circuit board 160 can move in the second direction (② direction) together with the sliding bracket 210 by the elastic force and / or restoring force of the curved portions R1 and R2.

In one embodiment, the waterproof member 270 may include at least one of silicone, polyurethane, rubber, or a cured in place gasket (CIPG) having elasticity capable of being tightly fitted into the through hole 1135.

[0169] According to various embodiments, due to the movement of the flexible printed circuit board 160 in the through hole 1135 caused by the frequent folding movement of the electronic device 100, the waterproof member 270 may not be able to maintain a close fit with the through hole 1135, and the waterproof function may be deteriorated. In order to solve these problems, the electronic device 100 may include a support structure to support the close fit of the waterproof member 270. In an embodiment, the electronic device 100 may include a magnet support 280 as a support structure, and the magnet support 280 includes a first magnet M1 disposed near the waterproof member 270 for the flexible printed circuit board 160 by an adhesive member T2 (e.g., a double-sided tape) and a second magnet M2 protruding onto the flexible printed circuit board 160 through an opening 1136 formed from the first space 1101 to the through hole 1135 and responding to a magnetic force (e.g., an attraction) from the first magnet M1. The first magnet M1 and the second magnet M2 may be coplanar with each other and magnetically attracted to each other along the y-axis direction. In one embodiment, the opening 1136 may be formed using the side wall 1131c provided by structural modification of the first support member 1131, and the magnet holder 280 may be fixed to the side wall 1131c so as to partially protrude into the through hole in a manner that the opening 1136 is sealed by an adhesive member T3 (e.g., double-sided tape). In one embodiment, at least a portion of the magnet holder 280 protruding into the through hole 1135 may be continuously contacted with the flexible printed circuit board 160 by attraction of the first magnet M1 and the second magnet M2.

[0170] According to various embodiments, the magnet holder 280 may include an insertion portion 281 inserted or extended into the opening 1136 and including a magnet receiving portion 2811 receiving the second magnet M2, and a flange 282 formed along an edge of the insertion portion 281 and fixed to the first support member 1131. In one embodiment, the second magnet M2 may be fixed to the magnet receiving portion 2811 by an adhesive member T4. Although not shown, the other end of the flexible printed circuit board may be fixed in the second space 1201 of the second housing 120 in substantially the same manner by the above-mentioned waterproof member 270 and a supporting structure (e.g., a supporting structure of the flexible printed circuit board 160 by the magnetic force of the first magnet M1 and the second magnet M2).

[0171] Fig.17a is a partial perspective view of an electronic device illustrating a state in which a flexible printed circuit board penetrates a first housing and a second housing according to various embodiments of the present disclosure. Fig.17b and Fig.17c 2 is a view illustrating an assembly process of a flexible printed circuit board according to various embodiments of the present disclosure. Fig.17d and Fig.17e is a view illustrating a state in which a magnet holder is assembled to a housing according to various embodiments of the present disclosure.

[0172] Although these drawings illustrate and describe the arrangement of the terminal portion 162 of the flexible circuit board 160 accommodated in the first housing 110 , the arrangement of the terminal portion 161 of the flexible circuit board 160 accommodated in the second housing 120 may have substantially the same configuration.

[0173] refer to Figures 17a to 17e The flexible printed circuit board 160 may be disposed in a manner such that one end of the flexible printed circuit board 160 penetrates or extends through a through hole 1135 formed from the first surface 1131a to the second surface 1131b of the first supporting member 1131 (eg, Fig.17b ). In this case, the waterproof member 270 provided on the flexible printed circuit board 160 may seal the through hole 1135 having the flexible printed circuit board 160 extending therethrough, and the first magnet M1 may be positioned near the waterproof member 270 on the flexible printed circuit board 160. Thereafter, the magnet holder 280 may be partially inserted into the opening 1136 formed in the side wall 1131c of the first support member 1131, thereby sealing the opening 1136 (e.g., Fig.17c ). In this case, the first magnet M1 can respond to the magnetic force (e.g., attraction) of the second magnet M2 by the proximity of the magnet holder 280, thereby keeping the flexible printed circuit board 160 in contact with the magnet holder 280. Therefore, even in the case of frequent folding movements of the electronic device 100, a portion of the flexible printed circuit board 160 can be kept in contact with the magnet holder by the magnetic force of the first magnet M1 and the second magnet M2, and have reduced movement along the through hole 1135, which can help reduce the poor waterproof phenomenon in which the waterproof member 270 disposed on the periphery is lifted or misaligned from the through hole 1135.
