以下、本開示の実施形態について、図面を参照して説明する。 Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.
図１および図２を参照して、本開示の一実施形態に係る電子機器１０について説明する。 An electronic apparatus 10 according to an embodiment of the present disclosure will be described with reference to FIGS. 1 and 2.
電子機器１０は、例えば防水性能を有する折り畳み可能な携帯電話であるが、他の任意の機器であってよい。概略として、電子機器１０は、例えば上部筐体１１と、下部筐体１２と、を備える。上部筐体１１および下部筐体１２は、ヒンジ部１３を介して開閉可能に連結される。上部筐体１１には、例えばディスプレイおよびレシーバ等が備えられてよい。下部筐体１２には、例えば物理キーおよびマイク等が備えられてよい。 The electronic device 10 is, for example, a foldable mobile phone having waterproof performance, but may be any other device. As an outline, the electronic device 10 includes, for example, an upper housing 11 and a lower housing 12. The upper housing 11 and the lower housing 12 are connected to each other via a hinge portion 13 so as to be opened and closed. The upper housing 11 may be provided with a display and a receiver, for example. The lower housing 12 may be provided with, for example, a physical key and a microphone.
ヒンジ部１３は、例えば図３に示すように、上部筐体１１の下部筐体１２側の端部に設けられた第１ヒンジ保持部１４と、下部筐体１２の上部筐体１１側の端部に設けられた第２ヒンジ保持部１５と、第１ヒンジ保持部１４および第２ヒンジ保持部１５によって保持されたチルトヒンジ１６と、を含んでよい。上部筐体１１および下部筐体１２は、チルトヒンジ１６の回転軸Ｘを中心に回動可能である。 For example, as shown in FIG. 3, the hinge portion 13 includes a first hinge holding portion 14 provided at an end portion of the upper housing 11 on the lower housing 12 side, and an end of the lower housing 12 on the upper housing 11 side. And a tilt hinge 16 held by the first hinge holding part 14 and the second hinge holding part 15. The upper housing 11 and the lower housing 12 are rotatable about the rotation axis X of the tilt hinge 16.
図１に示すように、上部筐体１１および下部筐体１２が折り畳まれた状態を、閉状態ともいう。閉状態において、上部筐体１１と下部筐体１２とが成す角度は、例えば略０°である。図２に示すように、上部筐体１１および下部筐体１２が開いた状態を、開状態ともいう。開状態において、上部筐体１１と下部筐体１２とが成す角度は、例えば１８０°未満である。上部筐体１１および下部筐体１２の、閉状態における内側をフロント側ともいう。上部筐体１１および下部筐体１２の、閉状態における外側をリア側ともいう。上部筐体１１および下部筐体１２それぞれの概略形状は、フロント側の面と、リア側の面と、４つの側面と、を有する６面体であってよい。 As shown in FIG. 1, the state in which the upper housing 11 and the lower housing 12 are folded is also referred to as a closed state. In the closed state, the angle formed by the upper housing 11 and the lower housing 12 is, for example, approximately 0 °. As shown in FIG. 2, the state in which the upper housing 11 and the lower housing 12 are opened is also referred to as an open state. In the open state, the angle formed by the upper housing 11 and the lower housing 12 is, for example, less than 180 °. The inside of the upper housing 11 and the lower housing 12 in the closed state is also referred to as a front side. The outside of the upper housing 11 and the lower housing 12 in the closed state is also referred to as the rear side. The schematic shape of each of the upper housing 11 and the lower housing 12 may be a hexahedron having a front side surface, a rear side surface, and four side surfaces.
図３に示すように、電子機器１０は、防水部材１７と、配線１８と、を更に備える。防水部材１７の概略形状は、筒形状である。防水部材１７は、可撓性を有する。防水部材１７の詳細については後述する。配線１８は、防水部材１７に挿通される。配線１８が挿通された防水部材１７は、上部筐体１１と下部筐体１２とを連結する。 As shown in FIG. 3, the electronic device 10 further includes a waterproof member 17 and a wiring 18. The schematic shape of the waterproof member 17 is a cylindrical shape. The waterproof member 17 has flexibility. Details of the waterproof member 17 will be described later. The wiring 18 is inserted through the waterproof member 17. The waterproof member 17 through which the wiring 18 is inserted connects the upper housing 11 and the lower housing 12.
例えば、防水部材１７は、第１ヒンジ保持部１４および第２ヒンジ保持部１５に挿通される。防水部材１７は、第１ヒンジ保持部１４および第２ヒンジ保持部１５に亘って設けられた貫通孔に挿入された円筒形状のシリンダ部材に挿通されてよい。シリンダ部材の中心軸は、第１ヒンジ保持部１４および第２ヒンジ保持部１５の貫通孔に挿入された状態で、チルトヒンジ１６の回転軸と略一致する。電子機器１０が開閉する際、シリンダ部材の外周面と、第１ヒンジ保持部１４および第２ヒンジ保持部１５に亘って設けられた貫通孔の内周面とが摺動する。防水部材１７の一方の端部が、上部筐体１１に接続される。防水部材１７の他方の端部が、下部筐体１２に接続される。防水部材１７を介して、上部筐体１１の内部の防水空間と、下部筐体１２の内部の防水空間とが連通する。図３に示すように、防水部材１７は、例えば１つ以上の箇所で折り曲げられて、上部筐体１１および下部筐体１２に接続されてよい。 For example, the waterproof member 17 is inserted through the first hinge holding part 14 and the second hinge holding part 15. The waterproof member 17 may be inserted through a cylindrical cylinder member that is inserted into a through hole provided across the first hinge holding part 14 and the second hinge holding part 15. The central axis of the cylinder member substantially coincides with the rotational axis of the tilt hinge 16 in a state where the cylinder member is inserted into the through holes of the first hinge holding portion 14 and the second hinge holding portion 15. When the electronic device 10 opens and closes, the outer peripheral surface of the cylinder member slides with the inner peripheral surface of the through hole provided across the first hinge holding portion 14 and the second hinge holding portion 15. One end of the waterproof member 17 is connected to the upper housing 11. The other end of the waterproof member 17 is connected to the lower housing 12. The waterproof space inside the upper housing 11 and the waterproof space inside the lower housing 12 communicate with each other through the waterproof member 17. As shown in FIG. 3, the waterproof member 17 may be bent at one or more locations, for example, and connected to the upper housing 11 and the lower housing 12.
配線１８は、上部筐体１１の内部に配置された電子部品と、下部筐体１２の内部に配置された電子部品とを、電気的に接続する。 The wiring 18 electrically connects an electronic component arranged inside the upper housing 11 and an electronic component arranged inside the lower housing 12.
図４および図５を参照して、防水部材１７について詳細に説明する。図４に示すように、防水部材１７は、筒部１９と、第１開口部２０と、第２開口部２１と、を有する。筒部１９、第１開口部２０、および第２開口部２１は、可撓性を有する任意の材質で一体的に形成される。当該材質は、例えばシリコンを含有する材質を含んでよい。 The waterproof member 17 will be described in detail with reference to FIGS. 4 and 5. As shown in FIG. 4, the waterproof member 17 includes a cylinder portion 19, a first opening portion 20, and a second opening portion 21. The cylinder part 19, the 1st opening part 20, and the 2nd opening part 21 are integrally formed with the arbitrary materials which have flexibility. The material may include, for example, a material containing silicon.
第１開口部２０は、筒部１９の一端に形成される。第１開口部２０は、筒部１９の中心軸に垂直な断面において長手方向および短手方向を有する任意の形状であってよい。長手方向および短手方向を有する形状は、例えばトラック形状および楕円形状等を含んでよい。 The first opening 20 is formed at one end of the cylindrical portion 19. The first opening 20 may have any shape having a longitudinal direction and a lateral direction in a cross section perpendicular to the central axis of the cylindrical portion 19. The shape having the longitudinal direction and the short direction may include, for example, a track shape and an elliptical shape.
第１開口部２０は、例えば図５に示すように、外周面から突出し全周に亘って延設された突出部２２を有する。第１開口部２０は、第１開口部２０の内部または内側にインサート成型された保持部材２３を有する。図５においては説明のため、保持部材２３を第１開口部２０から分離して示している。 For example, as shown in FIG. 5, the first opening 20 has a protrusion 22 that protrudes from the outer peripheral surface and extends over the entire periphery. The first opening 20 has a holding member 23 that is insert-molded inside or inside the first opening 20. In FIG. 5, the holding member 23 is shown separated from the first opening 20 for explanation.
保持部材２３は、剛性が比較的高い任意の材質で形成されてよい。例えば、保持部材２３は、金属または樹脂等の材質で形成される。保持部材２３は、筒部１９の中心軸に垂直な断面において、長手方向および短手方向を有し第１開口部２０に対応する形状である。 The holding member 23 may be formed of an arbitrary material having relatively high rigidity. For example, the holding member 23 is formed of a material such as metal or resin. The holding member 23 has a shape corresponding to the first opening portion 20 in the cross section perpendicular to the central axis of the cylindrical portion 19 and having a longitudinal direction and a short direction.
第１開口部２０は、上部筐体１１に接続される。例えば、上部筐体１１のヒンジ部１３側の端部における側面に孔部２４が設けられる。孔部２４は、長手方向および短手方向を有し第１開口部２０に対応する形状である。孔部２４の短手方向が、上部筐体１１の厚み方向と略一致してよい。 The first opening 20 is connected to the upper housing 11. For example, the hole 24 is provided on the side surface at the end of the upper housing 11 on the hinge 13 side. The hole 24 has a longitudinal direction and a short direction, and has a shape corresponding to the first opening 20. The short direction of the hole 24 may substantially coincide with the thickness direction of the upper housing 11.
第１開口部２０は、上部筐体１１の孔部２４に嵌入される。第１開口部２０が孔部２４に嵌入された状態で、突出部２２は、保持部材２３の外周面と孔部２４の内周面との間で押し潰される。突出部２２が押し潰されることによって、第１開口部２０の外周面と孔部２４の内周面との間が封止される。 The first opening 20 is fitted into the hole 24 of the upper housing 11. In a state where the first opening 20 is fitted in the hole 24, the protrusion 22 is crushed between the outer peripheral surface of the holding member 23 and the inner peripheral surface of the hole 24. When the protrusion 22 is crushed, the space between the outer peripheral surface of the first opening 20 and the inner peripheral surface of the hole 24 is sealed.
第２開口部２１は、筒部１９の他端に形成される。第２開口部２１は、下部筐体１２に接続される。第２開口部２１は、第１開口部２０と同様に構成されてよい。 The second opening 21 is formed at the other end of the cylindrical portion 19. The second opening 21 is connected to the lower housing 12. The second opening 21 may be configured in the same manner as the first opening 20.
筒部１９について詳細に説明する。筒部１９の少なくとも一部には、蛇腹形状２５が形成される。 The cylinder portion 19 will be described in detail. A bellows shape 25 is formed on at least a part of the cylindrical portion 19.
例えば、蛇腹形状２５は、筒部１９の中心軸方向における少なくとも一部の領域に形成されてよい。具体的には、蛇腹形状２５は、筒部１９において第１開口部２０の付け根近傍に形成される。蛇腹形状２５は、筒部１９と第１開口部２０との境界の位置または当該境界から離れた位置から、第２開口部２１側に延びてよい。 For example, the bellows shape 25 may be formed in at least a part of the region of the cylindrical portion 19 in the central axis direction. Specifically, the bellows shape 25 is formed near the base of the first opening 20 in the cylindrical portion 19. The bellows shape 25 may extend toward the second opening 21 from the position of the boundary between the cylindrical portion 19 and the first opening 20 or a position away from the boundary.
例えば、蛇腹形状２５は、筒部１９において第１開口部２０の長手方向に対応する位置に形成されてよい。具体的には、蛇腹形状２５は、筒部１９の周方向における一部の領域に形成される。当該一部の領域は、例えば図６に示すように、筒部１９の中心軸に垂直な断面において、中心軸から第１開口部２０の長手方向に位置する。 For example, the bellows shape 25 may be formed at a position corresponding to the longitudinal direction of the first opening 20 in the cylindrical portion 19. Specifically, the bellows shape 25 is formed in a partial region in the circumferential direction of the cylindrical portion 19. For example, as shown in FIG. 6, the partial region is located in the longitudinal direction of the first opening 20 from the central axis in a cross section perpendicular to the central axis of the cylindrical portion 19.
以上述べたように、本開示の一実施形態に係る電子機器１０において、防水部材１７の筒部１９の少なくとも一部に蛇腹形状２５が形成されている。かかる構成によれば、以下に説明するように、電子機器１０の防水構造の耐久性が向上する。 As described above, in the electronic device 10 according to the embodiment of the present disclosure, the bellows shape 25 is formed on at least a part of the cylindrical portion 19 of the waterproof member 17. According to this configuration, as described below, the durability of the waterproof structure of the electronic device 10 is improved.
防水部材１７は、例えば図３に示すように、１つ以上の箇所において折り曲げられた状態でヒンジ部１３内に配される。筒部１９における第１開口部２０の付け根において防水部材１７が折り曲げられると、応力集中によって当該付け根に切れまたは破れが発生し得る。これに対して、例えば筒部１９における第１開口部２０の付け根近傍に蛇腹形状２５が形成された構成によれば、当該付け根に切れまたは破れが発生する蓋然性が低減される。したがって、防水部材１７の耐久性が向上し、電子機器１０の防水構造の耐久性が向上する。 For example, as shown in FIG. 3, the waterproof member 17 is disposed in the hinge portion 13 in a state of being bent at one or more locations. When the waterproof member 17 is bent at the root of the first opening 20 in the tube portion 19, the root may be cut or torn due to stress concentration. On the other hand, for example, according to the configuration in which the bellows shape 25 is formed near the base of the first opening 20 in the cylindrical portion 19, the probability that the base will be cut or torn is reduced. Therefore, the durability of the waterproof member 17 is improved, and the durability of the waterproof structure of the electronic device 10 is improved.
上述したように、防水部材１７の第１開口部２０は、上部筐体１１のヒンジ部１３側の側面に設けられた孔部２４に嵌入される。防水部材１７の筒部１９は、第１開口部２０の付け根近傍において第１開口部２０の長手方向に折り曲げられて、第１ヒンジ保持部１４および第２ヒンジ保持部１５に亘って形成された貫通孔に挿通される。かかる場合、筒部１９における第１開口部２０の付け根であって、第１開口部２０の長手方向に対応する位置に応力集中が発生する。これに対して、筒部１９において第１開口部２０の長手方向に対応する位置に蛇腹形状２５が形成された構成によれば、筒部１９における第１開口部２０の付け根であって、第１開口部２０の長手方向に対応する位置における応力集中が軽減される。したがって、防水部材１７の耐久性が向上し、電子機器１０の防水構造の耐久性が向上する。 As described above, the first opening 20 of the waterproof member 17 is fitted into the hole 24 provided on the side surface of the upper housing 11 on the hinge 13 side. The cylindrical portion 19 of the waterproof member 17 is formed in the longitudinal direction of the first opening 20 in the vicinity of the base of the first opening 20 and extends over the first hinge holding portion 14 and the second hinge holding portion 15. It is inserted through the through hole. In such a case, stress concentration occurs at a position corresponding to the longitudinal direction of the first opening 20 at the root of the first opening 20 in the cylindrical portion 19. On the other hand, according to the configuration in which the bellows shape 25 is formed at a position corresponding to the longitudinal direction of the first opening 20 in the cylindrical portion 19, the root of the first opening 20 in the cylindrical portion 19, The stress concentration at the position corresponding to the longitudinal direction of the one opening 20 is reduced. Therefore, the durability of the waterproof member 17 is improved, and the durability of the waterproof structure of the electronic device 10 is improved.
本開示の一実施形態に係る電子機器１０において、第１開口部２０および孔部２４それぞれが、長手方向および短手方向を有する形状である。かかる構成によれば、以下に説明するように、電子機器１０の防水構造の耐久性が向上する。 In the electronic device 10 according to an embodiment of the present disclosure, each of the first opening 20 and the hole 24 has a shape having a longitudinal direction and a short direction. According to this configuration, as described below, the durability of the waterproof structure of the electronic device 10 is improved.
例えば、第１開口部２０および孔部２４それぞれが円形状である場合、組立作業者が防水部材１７を上部筐体１１および下部筐体１２に接続する際に、防水部材１７に捻れが発生する蓋然性が高い。防水部材１７に捻れが発生すると、防水部材１７に切れまたは破れが発生しやすくなる。防水部材１７に切れまたは破れが発生すると、電子機器１０の防水性能が低下する。これに対して、第１開口部２０および孔部２４それぞれが、長手方向および短手方向を有する形状である構成によれば、防水部材１７に捻れが発生する蓋然性が低減される。したがって、防水部材１７の耐久性が向上し、電子機器１０の防水構造の耐久性が向上する。 For example, when each of the first opening 20 and the hole 24 is circular, the waterproof member 17 is twisted when the assembly operator connects the waterproof member 17 to the upper housing 11 and the lower housing 12. The probability is high. When the waterproof member 17 is twisted, the waterproof member 17 is likely to be cut or torn. When the waterproof member 17 is cut or broken, the waterproof performance of the electronic device 10 is deteriorated. On the other hand, according to the configuration in which each of the first opening 20 and the hole 24 has a shape having a longitudinal direction and a lateral direction, the probability that the waterproof member 17 is twisted is reduced. Therefore, the durability of the waterproof member 17 is improved, and the durability of the waterproof structure of the electronic device 10 is improved.
本開示の一実施形態に係る電子機器１０において、防水部材１７の筒部１９における第１開口部２０の長手方向に対応する位置に蛇腹形状２５が形成されている。かかる構成によれば、以下に説明するように、例えば筒部１９の全周に亘って蛇腹形状２５が形成される構成と比較して、電子機器１０の厚みの増大を軽減可能である。 In the electronic device 10 according to an embodiment of the present disclosure, a bellows shape 25 is formed at a position corresponding to the longitudinal direction of the first opening 20 in the cylindrical portion 19 of the waterproof member 17. According to this configuration, as described below, for example, an increase in the thickness of the electronic device 10 can be reduced as compared with a configuration in which the bellows shape 25 is formed over the entire circumference of the cylindrical portion 19.
例えば、筒部１９の全周に亘って蛇腹形状２５を形成するためには、成型される筒部１９の内側に配される柱状の入れ子の全周面に、入れ子の中心軸方向に沿って凹凸形状を形成する。かかる場合、インサートされる保持部材２３が、例えば短手方向においてアンダーカットとなり得る。したがって、例えば入れ子に凹凸形状を形成しない場合と比較して、保持部材２３の短手方向の寸法を大きくする必要がある。上述したように、保持部材２３の短手方向は、上部筐体１１の厚み方向と略一致している。保持部材２３の短手方向の寸法の増大は、上部筐体１１の厚みの増大を引き起こし得る。これに対して、筒部１９における第１開口部２０の長手方向に対応する位置に蛇腹形状２５が形成された構成によれば、保持部材２３の短手方向の寸法の増大が軽減され、電子機器１０の厚みの増大が軽減される。 For example, in order to form the bellows shape 25 over the entire circumference of the cylindrical portion 19, along the central axis direction of the nesting, on the entire peripheral surface of the columnar nesting arranged inside the molded cylindrical portion 19. An uneven shape is formed. In such a case, the holding member 23 to be inserted can be undercut in the lateral direction, for example. Therefore, for example, it is necessary to increase the dimension of the holding member 23 in the short direction as compared with the case where the concavo-convex shape is not formed in the nest. As described above, the short direction of the holding member 23 is substantially the same as the thickness direction of the upper housing 11. An increase in the short dimension of the holding member 23 may cause an increase in the thickness of the upper housing 11. On the other hand, according to the configuration in which the bellows shape 25 is formed at a position corresponding to the longitudinal direction of the first opening 20 in the cylindrical portion 19, an increase in the dimension in the short direction of the holding member 23 is reduced. The increase in the thickness of the device 10 is reduced.
本発明を諸図面や実施形態に基づき説明してきたが、当業者であれば本開示に基づき種々の変形や修正を行うことが容易であることに注意されたい。したがって、これらの変形や修正は本発明の範囲に含まれることに留意されたい。例えば、各手段、各ステップ等に含まれる機能等は論理的に矛盾しないように再配置可能であり、複数の手段やステップ等を１つに組み合わせたり、あるいは分割したりすることが可能である。 Although the present invention has been described based on the drawings and embodiments, it should be noted that those skilled in the art can easily make various changes and modifications based on the present disclosure. Therefore, it should be noted that these variations and modifications are included in the scope of the present invention. For example, functions and the like included in each means and each step can be rearranged so as not to be logically contradictory, and a plurality of means and steps can be combined into one or divided. .
上述した一実施形態において、防水部材１７の筒部１９における第１開口部２０の付け根近傍に蛇腹形状２５を形成する構成について説明した。他の実施形態において、筒部１９における第２開口部２１の付け根近傍に蛇腹形状２５を形成してよい。例えば、筒部１９の第２開口部２１の付け根近傍において第２開口部２１の短手方向に対応する位置に、蛇腹形状２５が形成される。具体的には、蛇腹形状２５は、筒部１９の周方向における一部領域に形成される。当該一部の領域は、例えば図７に示すように、筒部１９の中心軸に垂直な断面において、中心軸から第２開口部２１の短手方向に位置する。かかる構成によれば、以下に説明するように、電子機器１０の防水構造の耐久性が向上する。 In the above-described embodiment, the configuration in which the bellows shape 25 is formed near the base of the first opening 20 in the cylindrical portion 19 of the waterproof member 17 has been described. In another embodiment, the bellows shape 25 may be formed near the base of the second opening 21 in the cylindrical portion 19. For example, the bellows shape 25 is formed at a position corresponding to the short direction of the second opening 21 in the vicinity of the root of the second opening 21 of the cylindrical portion 19. Specifically, the bellows shape 25 is formed in a partial region in the circumferential direction of the cylindrical portion 19. For example, as shown in FIG. 7, the partial region is located in the short direction of the second opening 21 from the central axis in a cross section perpendicular to the central axis of the cylindrical portion 19. According to this configuration, as described below, the durability of the waterproof structure of the electronic device 10 is improved.
例えば図３に示すように、防水部材１７の筒部１９は、第２開口部２１の付け根近傍において第２開口部２１の短手方向に折り曲げられて、下部筐体１２に接続される。かかる場合、筒部１９における第２開口部２１の付け根であって、第２開口部２１の短手方向に対応する位置に応力集中が発生する。これに対して、筒部１９において第２開口部２１の短手方向に対応する位置に蛇腹形状２５が形成された構成によれば、筒部１９における第２開口部２１の付け根であって、第２開口部２１の短手方向に対応する位置における応力集中が軽減される。したがって、防水部材１７の耐久性が向上し、電子機器１０の防水構造の耐久性が向上する。 For example, as shown in FIG. 3, the cylindrical portion 19 of the waterproof member 17 is bent in the short direction of the second opening 21 near the base of the second opening 21 and connected to the lower housing 12. In such a case, stress concentration occurs at the base of the second opening 21 in the cylindrical portion 19 and at a position corresponding to the short direction of the second opening 21. On the other hand, according to the configuration in which the bellows shape 25 is formed at a position corresponding to the short direction of the second opening 21 in the cylindrical portion 19, the root of the second opening 21 in the cylindrical portion 19, Stress concentration at the position corresponding to the short direction of the second opening 21 is reduced. Therefore, the durability of the waterproof member 17 is improved, and the durability of the waterproof structure of the electronic device 10 is improved.
上述した一実施形態において、筒部１９の少なくとも一部に蛇腹形状２５が形成される構成について説明した。筒部１９において蛇腹形状２５が形成される位置は、防水部材１７の形状およびヒンジ部１３の構造等に応じて任意に定められてよい。例えば、蛇腹形状２５は、防水部材１７がヒンジ部１３内に配された状態で筒部１９において応力集中が発生する箇所に形成されてよい。筒部１９において応力集中が発生する箇所は、例えば実験またはシミュレーションによって決定可能であってよい。 In the above-described embodiment, the configuration in which the bellows shape 25 is formed on at least a part of the cylindrical portion 19 has been described. The position at which the bellows shape 25 is formed in the cylindrical portion 19 may be arbitrarily determined according to the shape of the waterproof member 17 and the structure of the hinge portion 13. For example, the bellows shape 25 may be formed at a location where stress concentration occurs in the cylindrical portion 19 in a state where the waterproof member 17 is disposed in the hinge portion 13. The location where the stress concentration occurs in the cylindrical portion 19 may be determined by experiment or simulation, for example.
