Description

Electronic devices containing composite tapes

[0001] Embodiments of the present disclosure relate to electronic devices including composite tapes.

[0002] An electronic device may include a side frame (e.g., a side member) and at least one cover that forms a housing (e.g., a housing structure) by being coupled with the side frame. The electronic device may include a plurality of electrical components in an interior space of the housing and may have a sealing structure for protection from external moisture and / or foreign substances. This sealing structure may be achieved by a tape member that couples at least one cover member (e.g., a cover) to the side frame. The electronic device may require a separation structure that allows at least one cover to be easily separated from the side frame during maintenance.

[0003] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above is applicable as prior art related to the present disclosure.

[0004] An electronic device may include a housing (e.g., a housing structure) provided by a side frame (e.g., a side member or a side bezel structure) and at least a cover member (e.g., a cover) that is connected to the side frame using a tape member (e.g., an adhesive tape, a waterproof tape, a double-sided tape, or an adhesive member). The electronic device may include a plurality of electrical components (e.g., a circuit board, a battery, or various hardware components) arranged in an internal space of the housing. These plurality of electrical components may be protected from external moisture and / or foreign substances by being arranged in a sealed space of the housing formed by the side frame connected by the tape member and the at least one cover member. The tape member connects the side frame and the at least one cover member by an adhesive (e.g., an adhesive material), and may have a strong adhesive force that prevents the at least one cover member from being arbitrarily separated from the side frame under normal circumstances.

[0005] Electronic devices may require maintenance to replace malfunctioning internal electrical components or to separate at least one cover member from the side frame due to damage caused by external impact.

[0006] However, the strong adhesive strength of the tape element can make it difficult to separate at least one cover element from the side frame. Furthermore, the separation process is complex and maintenance costs can increase because special equipment that generates high temperatures is required to reduce the strong adhesive strength of the tape element.

[0007] Various embodiments of the present disclosure can provide an electronic device comprising a composite tape that allows at least one cover member to be easily separated from a side frame.

[0008] Various embodiments may provide an electronic device including a composite tape that allows at least one cover member to be easily separated from a side frame by a simple operation of a user without separate separation equipment.

[0009] Various embodiments may provide an electronic device comprising a composite tape that allows the cover member to be easily separated from the side frame with a relatively simple process and low cost.

[0010] However, the problem to be solved in this disclosure is not limited to the problem mentioned above, and may be expanded in various ways without departing from the spirit and scope of this disclosure.

[0011] According to various embodiments, an electronic device includes a side frame, a first cover member coupled to the side frame, and a composite tape attaching the first cover member to the side frame, wherein the composite tape includes at least one first tape member formed of a first material and a second tape member laminated to the at least one first tape member and formed of a second material that is extensible, and wherein at least a portion of the composite tape can be exposed through at least one opening formed in the first cover member while the first cover member is attached to the side frame via the composite tape.

[0012] According to various embodiments, an electronic device includes a front cover, a rear cover spaced apart from the front cover, a side frame arranged to surround a space between the front cover and the rear cover, a display arranged in the space and visible from the outside through at least a portion of the front cover, and a composite tape attaching the rear cover to the side frame, wherein the composite tape includes at least one first tape member formed of a first material, and a second tape member laminated to the at least one first tape member and formed of a second material that is extensible, and wherein at least a portion of the composite tape may be arranged to be exposed through at least one opening formed in the rear cover in a state in which the rear cover is attached to the side frame through the composite tape.

[0013] An electronic device according to exemplary embodiments of the present disclosure includes a first tape member and a second tape member laminated to the first tape member and formed of an extensible (e.g., stretchable) material, and includes a composite tape, at least a portion of which is externally operable to be exposed through at least one opening formed through a cover member, such that the adhesive force of the composite tape can be weakened by simply pulling and stretching the exposed portion of the composite tape, thereby inducing easy separation of the cover member. In addition, since the cover member can be easily separated from the side frame with just a simple operation by a user, the disassembly process for the cover member is simplified, and since no separate separate cover member disassembly equipment is required, it can help reduce maintenance costs.

[0014] In addition, various effects may be provided, either directly or indirectly, through this document.

[0015] The effects that can be obtained from the present disclosure are not limited to the effects mentioned above, and other effects that are not mentioned can be clearly understood by a person having ordinary skill in the art to which the present disclosure belongs from the description below.

In one embodiment, the display (101) may be attached to a first side (118a) of the extension member (1181) via a waterproof tape (150). In some embodiments, the waterproof tape (150) may be disposed between the front cover (102) and the first side (118a) of the extension member (1181). In one embodiment, the electronic device (100) may include a rear cover (111) disposed on a second side (118b) of the extension member (1181). In one embodiment, the rear cover (111) may be attached to the second side (118b) of the extension member (1181) via a composite tape (130).

[0071] According to various embodiments, the composite tape (130) may be exposed to be visible from the outside through an opening (111c) formed by a notch (111a) disposed on at least a portion of the edge of the rear cover (111). In one embodiment, the opening (111c) may be covered with a finishing member (120) (e.g., a decorative member) after assembly is completed so that the composite tape (130) is not visible from the outside, thereby providing an attractive appearance to the electronic device (100).

[0072] According to various embodiments, the composite tape (130) may include a first tape member (131) and an extensible second tape member (132) laminated to the first tape member (131). In one embodiment, the first tape member (131) may be positioned to face the second side (118b) of the extension member (1181). In one embodiment, the second tape member (132) may be positioned between the first tape member (131) and the rear cover (111) to face the rear cover (111). Thus, when the composite tape (130) is positioned, the second tape member (132) may be exposed through the opening (111c). In some embodiments, the composite tape (130) may be positioned such that the first tape member (131) is exposed through the opening (111c).

[0073] FIG. 5a is a diagram illustrating a state in which a side frame and a rear cover are attached through a composite tape according to various embodiments of the present disclosure. FIG. 5b is a diagram illustrating a state in which a composite tape according to various embodiments of the present disclosure is stretched.

[0074] Referring to FIGS. 5A and 5B, the composite tape (130) may include a first tape member (131) facing the side frame (118) and a second tape member (132) laminated on the first tape member (131) and facing the rear cover (111). In one embodiment, the first tape member (131) may include a cushioning layer (e.g., foam). In one embodiment, the second tape member (132) may be formed of an elastic material such as rubber, silicone, or urethane. In one embodiment, the first tape member (131) and the second tape member (132) may be attached to each other via an adhesive (P) (e.g., PSA). In one embodiment, the composite tape (130) may be attached to the rear cover (111) and the side frame (118) via an adhesive (P) (e.g., PSA).

[0075] According to various embodiments, when the composite tape (130) is pulled outwardly (e.g., in the direction of the arrow) through the opening (e.g., the opening (111c) of FIG. 4B) while the rear cover (111) and the side frame (118) are attached, the first tape member (131) may also be pulled together through the elongation (stretching) of the second tape member (132). Through the elongation of the composite tape (130), the bonding area between the composite tape (130) and the rear cover (111) and the bonding area between the composite tape and the side frame may be reduced, thereby helping to easily separate the rear cover (111) from the side frame (118). For example, when the composite tape is pulled, the bonding area may be reduced in a direction perpendicular to the pulling direction.

[0076] In some embodiments, the adhesive force (e.g., bonding force) between the first tape member (131) and the second tape member (132) of the composite tape (130) may be set to be greater than the adhesive force between the first tape member (131) and the side frame (118) and / or the adhesive force between the second tape member (132) and the rear cover (111), thereby helping to facilitate the separation of the rear cover (111).

[0077] FIG. 6a is a diagram illustrating a state in which a side frame and a rear cover are attached through a composite tape according to various embodiments of the present disclosure. FIG. 6b is a diagram illustrating a state in which a composite tape according to various embodiments of the present disclosure is stretched.

[0078] Referring to FIGS. 6A and 6B, the composite tape (130) may include a first tape member (131) facing the side frame (118) and a second tape member (132) laminated on the first tape member (131) and facing the rear cover (111). In one embodiment, the first tape member (131) may include a buffer layer (1311) (e.g., foam) as a base layer. In one embodiment, the composite tape (130) may include a substrate layer (1312) (e.g., PET or PU) laminated on the buffer layer (1311) as an additional layer. In one embodiment, the buffer layer (1311) may perform a buffering function for the composite tape (130). In one embodiment, the substrate layer (1312) may be used for self-support of the first tape member (131). In one embodiment, the substrate layer (1312) may help improve productivity by providing rigidity to the first tape member (131) and / or the composite tape (130) (by making them relatively less susceptible to bending). In one embodiment, the first tape member (131) and the second tape member (132) may be attached to each other via an adhesive (P) (e.g., a pressure sensitive adhesive, PSA). In one embodiment, the composite tape (130) may be attached to the rear cover (111) and the side frame (118) via an adhesive (P) (e.g., PSA).

[0079] According to various embodiments, when the composite tape (130) is pulled outwardly (e.g., in the direction of the arrow) through the opening (e.g., the opening (111c) of FIG. 4B) while the rear cover (111) and the side frame (118) are attached, the base layer (1312) of the first tape member (131) may also be pulled together through the elongation (stretching) of the second tape member (132). In this case, the buffer layer (1311) may be left on the side frame (118). In some embodiments, when the composite tape (130) is pulled, the buffer layer (1311) may also be pulled together while being attached to the rear cover (111). In one embodiment, the stretching of the composite tape (130) may help facilitate separation of the rear cover (111) from the side frame (118) by reducing the bonding area between the composite tape (130) and the rear cover (111) and the bonding area between the composite tape (130) and the side frame (118). For example, when the composite tape (130) is pulled, the bonding area may be reduced in a direction perpendicular to the pulling direction.

[0080] In some embodiments, the adhesive force (e.g., bonding force) between the first tape member (131) and the second tape member (132) of the composite tape (130) may be set to be greater than the adhesive force between the first tape member (131) and the side frame (118) and / or the adhesive force between the second tape member (132) and the rear cover (111), thereby helping to facilitate the separation of the rear cover (111).

[0081] FIGS. 7A and 7B are diagrams illustrating a process for separating a composite tape from an electronic device according to various embodiments of the present disclosure.

[0082] In describing the electronic device (100) of FIG. 7A and FIG. 7B, the same reference numerals are given to components that are substantially the same as those of the electronic device (100) of FIG. 4B, and a detailed description thereof may be omitted.

[0083] Referring to FIGS. 7A and 7B , the electronic device (100) may include a side frame (118), a display (101) disposed on a first side (118a) of the side frame (118), and a rear cover (111) disposed on a second side (118b). In one embodiment, the rear cover (111) may be attached to the side frame (118) via a composite tape (130) disposed between the display and the second side (118b) along an edge. In one embodiment, the composite tape (130) may be disposed so as to be at least partially exposed through an opening (111c) formed through a notch (111a) of the rear cover (111). In one embodiment, the exposed composite tape (130) may be disposed so as to be invisible from the outside by at least partially filling the opening (111c) through a finishing member (120) (e.g., a decorative member). In one embodiment, the closing member (120) is formed of a rigid material (e.g., PC or metal) or an elastic material (e.g., rubber, silicone or urethane) and is accommodated in the opening (111c) in a manner such as by force-fitting or taping, so that it cannot be arbitrarily detached.

[0084] According to various embodiments, when maintenance is required, such as when replacement of electrical components arranged in the interior space of the housing (110) is required or replacement of the rear cover (111) is required, the closing member (120) can be removed from the opening (111c). For example, the closing member (120) can be easily removed using a simple tool with a sharp end (e.g., a needle or pin, etc.), or can be simply removed by a user's fingernail, etc. In one embodiment, at least a portion of the composite tape (130) can be exposed so as to be visible from the outside through the opening (111c) from which the closing member (120) has been removed. In one embodiment, at least a portion of the composite tape (130) exposed through the opening (111c) can be pulled outward by a user (worker) (e.g., pulled), and the composite tape (130) including the extensible tape member (132) can be elongated to reduce the bonding area with the rear cover (111) and the side frame (118), thereby inducing easy separation of the rear cover (111) from the side frame (118).

[0085] FIG. 8A is an exploded perspective view of a composite tape according to various embodiments of the present disclosure. FIG. 8B is a cross-sectional view of a portion of an electronic device to which the composite tape of FIG. 8A is applied according to various embodiments of the present disclosure.

[0086] In describing the composite tape (130-1) and electronic device (100) of FIGS. 8a and 8b, the same symbols are given to components that are substantially the same as those of the composite tape (130) and electronic device (100) of FIG. 4b, and a detailed description thereof may be omitted.

[0087] Referring to FIGS. 8A and 8B , the composite tape (130-1) may include a first tape member (131) and a second tape member (132) laminated to the first tape member (131). In one embodiment, the second tape member (132) may be formed of an extensible material as described above. In one embodiment, the first tape member (131) may include a first sub-tape (1313) and a second sub-tape (1314). In one embodiment, the composite tape (130-1) may be configured such that the second tape member (132) is disposed between the first sub-tape (1313) and the second sub-tape (1314). In some embodiments, the second tape member (132) may be disposed between the first sub-tape (1313) and the side frame (118) or between the second sub-tape (1314) and the rear cover (111). In this case, the first sub-tape (1313) and the second sub-tape (1314) may be directly laminated. In one embodiment, each of the first sub-tape (1313) and the second sub-tape (1314) may have a self-laminating structure that is substantially the same as the first tape member (131) of FIG. 5A or the first tape member (131) of FIG. 6A described above.

[0088] According to various embodiments, when the rear cover (111) is attached to the side frame (118) via the composite tape (130-1), the second tape member (132) may be arranged so as to be at least partially exposed through an opening (111c) formed through the rear cover (111). In one embodiment, the opening (111c) may be covered so as not to be visible from the outside via the closing member (130). In this case, the closing member (130) may be arranged so as to be attached through an additional tape (133) (e.g., double-sided tape) laminated to the second tape member (132) exposed through the opening (111c).

[0089] FIG. 9a is an exploded perspective view of a composite tape according to various embodiments of the present disclosure. FIG. 9b is a configuration diagram of a rear cover on which the composite tape of FIG. 9a is arranged according to various embodiments of the present disclosure.

[0090] In describing the composite tape (130-2) of FIGS. 9a and 9b, the same symbols are given to components that are substantially the same as the composite tape (130) of FIG. 4b, and a detailed description thereof may be omitted.

[0091] Referring to FIGS. 9A and 9B, the composite tape (130-2) may include a first tape member (131) and a second tape member (132') laminated on the first tape member (131). In one embodiment, the first tape member (131) may have a self-laminating structure that is substantially the same as the first tape member (131) of FIG. 5A or the first tape member (131) of FIG. 6A described above. In one embodiment, the second tape member (132') may have a size corresponding to the entire area of ​​the rear cover (111). For example, the second tape member (132') may be formed to have a relatively large area, thereby helping to reduce the phenomenon of fracture during withdrawal, since fracture may occur when a portion exposed through the opening (111c) is pulled. In this case. The composite tape (130-2) may include a single-sided tape (134) disposed between the first tape member (131) and the second tape member (132'). In one embodiment, the single-sided tape (134) has an adhesive layer formed only in the direction of the rear cover (111) (e.g., the -z axis direction), thereby eliminating unnecessary adhesive layers between electrical components and / or structures disposed in the internal space of the electronic device (100).

[0092] FIG. 10A is an exploded perspective view of a composite tape according to various embodiments of the present disclosure. FIG. 10B is a cross-sectional view of a portion of an electronic device to which the composite tape of FIG. 10A is applied according to various embodiments of the present disclosure.

[0093] In describing the composite tape (130-3) and the electronic device (100) of FIGS. 10a and 10b, the same symbols are given to components that are substantially the same as those of the composite tape (130-1) and the electronic device (100) of FIGS. 8a and 8b, and a detailed description thereof may be omitted.

[0094] Referring to FIGS. 10A and 10B , the composite tape (130-3) may include a first sub-tape (1313), a second sub-tape (1314), and a second tape member (132) disposed between the first sub-tape (1313) and the second sub-tape (1314). In one embodiment, each of the first sub-tape (1313) and the second sub-tape (1314) may have a self-laminating structure substantially the same as the first tape member (131) of FIG. 5A or the first tape member (131) of FIG. 6A described above. In one embodiment, the second tape member (132) may be formed of an extensible material. In one embodiment, the composite tape (130-3) may include a string member (1315) (e.g., a wire member) disposed between the second tape member (132) and the first sub-tape (1313). In one embodiment, the string member (1315) may be positioned so as not to be exposed externally between the second tape member (132) and the first sub-tape (1313). In one embodiment, the adhesive force between the second tape member (132) and the first sub-tape (1313) may be set relatively weakly through the string member (1315), thereby helping to facilitate separation of the rear cover (111) when the composite tape (130-3) is pulled out through the opening (111c). In one embodiment, the string member (1315) may be formed of a metal wire, polymer, or fiber material. In some embodiments, the string member (1315) may be positioned between the second tape member (132) and the second sub-tape (1314).

[0095] FIG. 11 is a cross-sectional view of a portion of an electronic device to which a composite tape according to various embodiments of the present disclosure is applied.

[0096] In explaining the arrangement structure of the composite tape (130) of FIG. 11, the same symbols are given to components that are substantially the same as the arrangement structure of the composite tape (130) of FIG. 4b, and a detailed description thereof may be omitted.

[0097] Referring to FIG. 11, the composite tape (130) may include a first tape member (131) and an extensible second tape member (132) laminated on the first tape member (131). In one embodiment, the first tape member (131) may be positioned to face the second side (118b) of the extension member (1181). In one embodiment, the second tape member (132) may be positioned between the first tape member (131) and the rear cover (111) to face the rear cover (111). Therefore, when the composite tape (130) is positioned, the second tape member (132) may be exposed through the opening (111c).

[0098] According to various embodiments, the composite tape (130) may be exposed through the opening (111c) and may include a folded area (132a) (e.g., a bending area) formed through the second tape member (132). In one embodiment, the folded area (132a) may be an area arranged so that the ends of the second tape member (132) overlap each other when folded 180 degrees. In one embodiment, the folded area (132a) of the second tape member (132) may be configured to be separable through a peeling member (135) (e.g., a single-sided tape). Therefore, when the second tape member (132) is pulled out through the opening (111c), a relatively long pull-out length is secured, thereby helping to facilitate the pull-out of the composite member (130).

[0099] FIG. 12a is a diagram illustrating a rear view of an electronic device according to various embodiments of the present disclosure. FIG. 12b is a partial perspective view of an electronic device showing a state in which a composite tape is separated according to various embodiments of the present disclosure.

[0100] According to various embodiments, even if the electronic device (100) has a configuration in which an opening (111c) formed through a portion of the rear cover (111) is covered by a closing member (120) so that the composite tape (130) is not visible, the closing member (120) may damage the aesthetic appearance of the electronic device.

[0101] Referring to FIGS. 12a and 12b, the opening (111d) for withdrawing the composite tape (130) may be arranged to be covered by a decorative member (112a) (e.g., a finishing member) arranged to at least surround the periphery of the camera module (112). For example, when the electronic device (100) is assembled, the opening (111d) is covered by the decorative member (112a) for the camera module (112), thereby making the separate finishing member (120) described above unnecessary and helping to form an attractive appearance of the electronic device (100). In this case, at least a portion of the composite tape (130) may include an extension portion (130a) that extends to a position overlapping the opening (111d) when the rear cover (111) is viewed from above.

[0102] According to various embodiments, when the electronic device (100) requires maintenance, such as replacement of electrical components arranged in the interior space of the housing (110) or replacement of the rear cover (111), the decorative member (112a) may be removed from the opening (111c) arranged to surround the camera module (112). In one embodiment, at least a portion of the composite tape (130) may be exposed to be visible from the outside through the opening (111d) from which the closing member (120) has been removed. In one embodiment, at least a portion of the composite tape (130) exposed through the opening (111d) can be pulled outward by a user (worker) (e.g., pulled), and the composite tape (130) including the extensible tape member (e.g., the second tape member (132) of FIG. 3b) can be stretched to weaken the adhesive force through a decrease in the adhesive area, thereby inducing easy separation of the rear cover (111) from the side frame (118).

[0103] FIG. 13A is a schematic diagram of a rear cover to which a composite tape is applied according to various embodiments of the present disclosure. FIG. 13B is a cross-sectional view of a portion of the composite tape taken along line 13B-13B of FIG. 13A according to various embodiments of the present disclosure.
