In the configuration provided with such a waterproof packing, in order to ensure the waterproof property, it is necessary that the entire circumference of the waterproof packing is in close contact with the casing and the lid.
　しかし、特許文献１、２に示したような構成においては、蓋体は、互いに対向する２辺でのみ筺体に固定される。この構成のため、蓋体の長手方向の中間部においては、蓋体が撓んで蓋体が筺体から浮いてしまう可能性がある。すると、この部分において防水パッキンの密着性が損なわれ、防水性が低下してしまう。 However, in the configuration as shown in Patent Documents 1 and 2, the lid is fixed to the casing only on two sides facing each other. Due to this configuration, there is a possibility that the lid body bends and the lid body floats from the housing in the middle part in the longitudinal direction of the lid body. Then, in this part, the adhesiveness of waterproof packing is impaired, and waterproofness will fall.
　また、近年、電子機器の高性能化により、電池パックの大型化が予想される。すると、電池パックの重量も増大するため、電子機器を落下させた場合等において、その衝撃により電池パックが飛び出そうとする力が強力になると考えられる。これにより蓋体が撓んで筺体から浮いたり、蓋体が脱落してしまう可能性が高まる。
　本発明の目的の一例は、蓋体を強固に固定して蓋体の脱落を防ぐとともに、防水性の低下を防ぐことのできる電子機器を提供することである。 In recent years, battery packs are expected to increase in size due to higher performance of electronic devices. Then, since the weight of the battery pack also increases, it is considered that when the electronic device is dropped, the force for the battery pack to pop out by the impact becomes strong. This increases the possibility that the lid body is bent and floats from the housing, or the lid body falls off.
An example of an object of the present invention is to provide an electronic device that can firmly fix a lid body to prevent the lid body from falling off and prevent deterioration in waterproofness.
　本発明の実施態様に係る電子機器は、電子機器の外殻をなし、電池を収容する収容凹部を備えた筺体と、前記収容凹部を塞ぐよう、前記筺体に着脱可能に装着され、第１端部、第２端部、および前記第１端部と前記第２端部の間に位置する中間部を有する蓋体と、前記収容凹部の内部に設けられ、スライド方向である一方向に沿って、前記蓋体の第１端部および前記蓋体の第２端部のいずれかに向かってスライドするロックフレームとを備える。前記ロックフレームは、前記スライド方向に直交する方向に延びるベースフレーム部と、前記ベースフレーム部から前記スライド方向に延びるサイドフレーム部と、前記ベースフレーム部に設けられ、前記蓋体の第１端部に向かって前記ロックフレームをスライドさせることで前記蓋体の第１端部に係合し、前記蓋体の第２端部に向かって前記ロックフレームをスライドさせることで前記蓋体の第１端部との係合が解除される第一の係合部と、前記サイドフレーム部に設けられ、前記蓋体の第１端部に向かってに前記ロックフレームをスライドさせることで前記蓋体の中間部に係合し、前記蓋体の第２端部に向かって前記ロックフレームをスライドさせることで前記蓋体の中間部との係合が解除される第二の係合部と、前記筺体の外部から前記ロックフレームをスライドさせる操作部とを備える。 An electronic device according to an embodiment of the present invention is an outer shell of an electronic device, a housing provided with a housing recess for housing a battery, and a detachably mounted to the housing so as to close the housing recess. A lid body having a portion, a second end portion, and an intermediate portion positioned between the first end portion and the second end portion, and provided in the housing recess, along one direction which is a sliding direction And a lock frame that slides toward either the first end of the lid or the second end of the lid. The lock frame is provided on a base frame portion extending in a direction perpendicular to the sliding direction, a side frame portion extending in the sliding direction from the base frame portion, and a first end portion of the lid body. The lock frame is slid toward the first end of the lid, and the lock frame is slid toward the second end of the lid. A first engagement part that is disengaged from the part and an intermediate part of the lid body by sliding the lock frame toward the first end of the lid body, provided on the side frame part A second engagement portion that is engaged with the portion and is disengaged from the intermediate portion of the lid body by sliding the lock frame toward the second end portion of the lid body, Before from outside And an operation section for sliding the lock frame.
　本発明によれば、収容凹部を塞ぐように蓋体をセットした状態で、操作部によりロックフレームをスライド移動させることで、第一の係合部により蓋体の一端部が係合され、第二の係合部により蓋体の中間部が係合される。これにより、蓋体を強固に固定して蓋体の脱落を防ぐ。さらに、蓋体の一端部だけでなく中間部でも係合することによって蓋体の撓みを抑え、防水性の低下を防ぐことができる。 According to the present invention, in a state in which the lid is set so as to close the housing recess, the lock frame is slid by the operation portion, whereby the first engagement portion engages one end of the lid, The middle part of the lid is engaged by the second engaging part. Thereby, the lid is firmly fixed to prevent the lid from falling off. Furthermore, by engaging not only at one end portion of the lid but also at the intermediate portion, it is possible to suppress the deflection of the lid and prevent deterioration of waterproofness.

　まず、電池パック２０を斜めにして電池パック収容凹部１６に挿入し、電池パック２０の凹部２２をリア筐体１１Ｂの凸部１９に嵌合させる。次いで、電池パック２０の突起２１が形成されている側を電池パック収容凹部１６側に収める。
　このとき、図１１Ａ、１１Ｂに示すように、電池ロック部材５０は一側（図１１Ａ、１１Ｂの右側）にスライドした状態である。即ち、電池ロック部材５０はフリー状態である。これにより、突起２１は、溝部５２の突起通過部５５に挿入される。
　次いで、電池ロック部材２０を他側にスライドさせる。これにより、図１２Ａ、１２Ｂに示すように、突起２１は溝部５２の突起収容部５４に入り込み、電池パック２０の脱落が規制される。 In such a configuration, the battery pack 20 is housed in the battery pack housing recess 16 with the lid 30 removed from the opening 15.
First, the battery pack 20 is inserted obliquely into the battery pack housing recess 16, and the recess 22 of the battery pack 20 is fitted to the protrusion 19 of the rear housing 11B. Next, the side on which the protrusion 21 of the battery pack 20 is formed is housed in the battery pack housing recess 16 side.
At this time, as shown in FIGS. 11A and 11B, the battery lock member 50 is slid to one side (the right side of FIGS. 11A and 11B). That is, the battery lock member 50 is in a free state. Thereby, the projection 21 is inserted into the projection passage portion 55 of the groove portion 52.
Next, the battery lock member 20 is slid to the other side. Thereby, as shown in FIGS. 12A and 12B, the protrusion 21 enters the protrusion accommodating portion 54 of the groove portion 52, and the battery pack 20 is prevented from falling off.
　そして、図１３Ａ～１３Ｉに示すように、蓋体３０を、開口部１５に嵌め込む。このとき、蓋体３０の筒状壁部３２を内周壁部１７の内側に挿入し、シールリング３３を内周壁部１７に突き当てた状態とする。図１５に示すように、蓋体３０を取り付けることによって、蓋体３０の裏面３１ａに形成されている規制突起３７が電池ロック部材５０の一側（フリー状態）へのスライドを規制するように、スライドツマミ部５３と略当接する位置に挿入される。
　この状態で、操作突起４４はリア筺体１１Ｂと蓋体３０に形成された凹部６０、６１から、筺体１１の外部に露出する。 Then, the lid 30 is fitted into the opening 15 as shown in FIGS. 13A to 13I. At this time, the cylindrical wall portion 32 of the lid body 30 is inserted inside the inner peripheral wall portion 17 and the seal ring 33 is brought into contact with the inner peripheral wall portion 17. As shown in FIG. 15, by attaching the lid body 30, the regulation protrusion 37 formed on the back surface 31 a of the lid body 30 regulates the slide to one side (free state) of the battery lock member 50. It is inserted at a position that substantially contacts the slide knob portion 53.
In this state, the operation projection 44 is exposed to the outside of the casing 11 from the recesses 60 and 61 formed in the rear casing 11B and the lid 30.
　この後、操作突起４４を、開口部１５の短辺１５ｄ側に向けてスライドさせることにより、ロックフレーム４０を、溝１８内で、短辺１５ｄ側にスライド移動させる。すると、図１４Ａ～１４Ｉに示すように、ロックフレーム４０の係合突起４５が蓋体３０の溝３６に噛み合う（図１４Ｈ参照）。それとともに、ロックフレーム４０の係合段部４６が、短辺１５ａにおいて内周壁部１７の外周面に形成された係合爪６４に係合する（図１４Ｉ参照）。
　係合突起４５の突出寸法Ｓ１は、係合段部４６の突出寸法Ｓ２よりも小さい。このため、係合段部４６と係合爪６４との係合を先行させ、ロックフレーム４０をリア筺体１１Ｂに係合させた後に、係合突起４５と溝３６を係合させてロックフレーム４０で蓋体３０を係合させることができる。
　これと同時に、図１４Ｆ、１４Ｇに示すように、ロックフレーム４０の係合フック４３が、蓋体３０の裏面３１ａに形成された係合爪３５に係合する。具体的には、係合フック４３の係合溝４３ｃに係合爪３５の平行壁部３５ｂが挿入されることで、係合フック４３の平行壁部４３ｂと係合爪３５の平行壁部３５ｂとが対向した状態となる。これによって、蓋体３０のフェイスプレート３１がリア筺体１１Ｂの表面１１ｒから離間した方向に変位するのが拘束される。 Thereafter, the operation projection 44 is slid toward the short side 15d of the opening 15 to slide the lock frame 40 toward the short side 15d in the groove 18. Then, as shown in FIGS. 14A to 14I, the engagement protrusion 45 of the lock frame 40 meshes with the groove 36 of the lid 30 (see FIG. 14H). At the same time, the engaging step portion 46 of the lock frame 40 engages with an engaging claw 64 formed on the outer peripheral surface of the inner peripheral wall portion 17 at the short side 15a (see FIG. 14I).
The protrusion dimension S1 of the engagement protrusion 45 is smaller than the protrusion dimension S2 of the engagement step portion 46. For this reason, after the engagement of the engagement step portion 46 and the engagement claw 64 is preceded and the lock frame 40 is engaged with the rear housing 11B, the engagement protrusion 45 and the groove 36 are engaged, and the lock frame 40 is engaged. The lid 30 can be engaged.
At the same time, as shown in FIGS. 14F and 14G, the engagement hook 43 of the lock frame 40 engages with the engagement claw 35 formed on the back surface 31 a of the lid 30. Specifically, the parallel wall portion 35 b of the engagement hook 43 and the parallel wall portion 35 b of the engagement claw 35 are inserted by inserting the parallel wall portion 35 b of the engagement claw 35 into the engagement groove 43 c of the engagement hook 43. Are in a state of facing each other. This restrains the face plate 31 of the lid 30 from being displaced in a direction away from the surface 11r of the rear housing 11B.
　これによって、蓋体３０が、開口部１５の短辺１５ａに位置する係合突起４５と、長辺１５ｂ、１５ｃに位置する係合フック４３とにより、その三辺においてロックフレーム４０を介してリア筺体１１Ｂに固定され、開口部１５から外れない状態となる。これにより、蓋体３０が強固に固定され、フェイスプレート３１が撓むのを防ぐことができる。したがって、蓋体３０の脱落を確実に防止し、シールリング３３による防水性を確実に発揮することができる。
　また、ロックフレーム４０をスライドさせるという１つの動作で蓋体３０を確実に固定できる。
　さらに、一つのロックフレーム４０により蓋体３０を三辺で固定できるため、低コストで上記効果が得られる。
　また、携帯電話端末１０の外観面から視認できるロックフレーム４０は、操作突起４４のみである。操作突起４４の形状は従来からの蓋体のロック構造と変りないので、デザインの自由度が損なわれることもない。 As a result, the lid 30 is provided with the engagement protrusion 45 located on the short side 15a of the opening 15 and the engagement hook 43 located on the long sides 15b and 15c, and the rear side of the lid 30 via the lock frame 40. It will be in the state which is fixed to the housing 11B and cannot be removed from the opening part 15. FIG. Thereby, the lid 30 is firmly fixed, and the face plate 31 can be prevented from being bent. Accordingly, it is possible to reliably prevent the lid 30 from falling off and to reliably exhibit the waterproof property by the seal ring 33.
Further, the lid 30 can be reliably fixed by one operation of sliding the lock frame 40.
Furthermore, since the lid 30 can be fixed on three sides by one lock frame 40, the above-described effects can be obtained at low cost.
Further, the lock frame 40 that can be visually recognized from the appearance of the mobile phone terminal 10 is only the operation protrusion 44. Since the shape of the operation projection 44 is not different from the conventional lid lock structure, the degree of freedom in design is not impaired.
