[0001] The present invention relates to an electronic device in which a battery is accommodated in a housing. Background Art

[0002] Electronic devices such as notebook PCs and tablet PCs generally include a housing formed into a flat box shape by overlapping and connecting two housing members, and a battery housed in the housing (see, for example, Patent Document 1).

[0003] Patent Document 1: Japanese Patent No. 6212322

[0004] Currently, the above-mentioned batteries use lithium-ion batteries that can achieve both thinness and large capacity, and lithium polymer batteries that can achieve further thinness by wrapping the battery cells with film packaging. Although rare, these batteries sometimes expand to 400-500% or more in volume during use due to poor manufacturing. Such defective batteries need to be replaced, but there is a concern that the frame parts will be plastically deformed or cracked during expansion. Therefore, not only the battery needs to be replaced, but also the frame needs to be replaced, which increases the cost and effort of maintenance. Summary of the invention

[0005] The present invention has been made in consideration of the above-mentioned problems of the prior art, and an object of the present invention is to provide an electronic device capable of suppressing damage to a housing member even when a battery failure occurs.

The battery is arranged in the frame at a position closer to the second edge portion side than the first edge portion side, and the end face of the first engaging piece and the end face of the first engaging portion respectively have a first inclined surface that gradually inclines from the first edge portion side to the second edge portion side as they tend from the end side of the one party toward the end side of the other party, and the end face of the second engaging piece and the end face of the second receiving portion respectively have a second inclined surface that gradually inclines from the second edge portion side to the first edge portion side as they tend from the end side of the one party toward the end side of the other party.

[0007] According to the above aspect of the present invention, even when a battery failure occurs, damage to the frame member can be suppressed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] Hereinafter, the electronic device according to the present invention will be described in detail with reference to the drawings by listing preferred embodiments.

[0022] Figure 1 FIG. 1 is a top view of an electronic device 10 according to an embodiment. In this embodiment, the electronic device 10 is illustrated as a notebook PC, but the electronic device to which the present invention can be applied may be a tablet PC, a smartphone, or a portable game console, in addition to a notebook PC. Figure 1 As shown, the electronic device 10 has a structure in which a housing 12 and a cover 14 are connected by a hinge 16 so as to be relatively rotatable. Figure 1 The state (usage mode) in which the cover body 14 is opened from the frame body 12 is shown.

[0023] The cover 14 is formed in a flat box shape. A display 18 is mounted on the front of the cover 14. The display 18 is, for example, an organic EL or a liquid crystal. The cover 14 is connected to the rear edge of the frame 12 by a hinge 16. Figure 1In the embodiment of the present invention, the cover 14 is connected to the frame 12 by a pair of left and right hinges 16. The hinge 16 may be a long structure extending in the X direction, such as a so-called single-bar hinge.

[0024] Next, for the frame 12, Figure 1 In the usage mode shown, in the direction viewed from the user who is viewing the display 18 and operating the keyboard 20, the left and right width directions are referred to as X1 and X2 directions, the front and rear depth directions are referred to as Y1 and Y2 directions, and the top and bottom thickness directions are referred to as Z1 and Z2 directions. The X1 and X2 directions are sometimes collectively referred to as the X direction, and the Y1 and Y2 directions, and the Z1 and Z2 directions are sometimes referred to as the Y direction and the Z direction.

[0025] The frame 12 is a structure formed by connecting a first frame member 22 and a second frame member 23. The frame 12 is formed in a flat box shape. The keyboard 20 is fixed to the second frame member 23 and faces the surface 12a of the frame 12. On the surface 12a of the frame 12, a touch pad 24 is provided in front of the keyboard 20. Inside the frame 12, in addition to accommodating electronic components such as a motherboard 26 on which a CPU and a memory are mounted, a cooling module 27 for cooling the CPU is also accommodated.

[0026] In addition, a battery 28 serving as a power source for the electronic device 10 is housed inside the frame 12. The battery 28 is, for example, a lithium-ion battery or a lithium polymer battery. In the present embodiment, a lithium polymer battery is used. The battery 28 has, for example, a generally rectangular plate shape that is longer in the X direction and shorter in the Y direction. The battery 28 is arranged in the frame 12 at a position from the center in the Y direction to a position close to the Y1 side. Therefore, the battery 28 extends in the X direction at a position close to the edge portion 22d and the vertical wall 23d of the frame 12. The motherboard 26 is arranged to be arranged on the Y2 side of the battery 28 and to extend in the X direction.

[0027] Next, a specific configuration example of the frame body 12 will be described.

[0028] Figure 2 It is a bottom view of the frame 12 . Figure 3A It is along Figure 2 Schematic cross-sectional view along line III-III. Figure 3B Yes means Figure 3A The cross-sectional view of the battery 28 in the expanded state is shown. Figure 1 to Figure 3A As shown, the first frame member 22 is formed into a substantially rectangular plate shape. The second frame member 23 is formed into a substantially rectangular bathtub shape. The frame members 22 and 23 can be formed of metal materials such as magnesium or aluminum, resin materials such as ABS resin or glass fiber reinforced plastic, or carbon materials such as carbon fiber reinforced plastic.

[0029] The first frame body part 22 forms the bottom surface 12b of the frame body 12. The first frame body part 22 has a pair of edge portions 22a, 22b extending along the Y direction and substantially parallel to each other, and a pair of edge portions 22c, 22d extending along the X direction and substantially parallel to each other. The second frame body part 23 has vertical walls 23a to 23d forming the four sides of the frame body 12 on the four sides, and the bottom surface 12b side is open. The vertical walls 23a to 23d are in close contact with the edge portions 22a to 22d, respectively. The first frame body part 22 becomes a cover part that closes the opening on the bottom surface 12b side of the second frame body part 23. The vertical wall 23c forming the side surface on the Y2 side of the frame body 12 has a concave portion 16a near the left and right ends. The concave portion 16a is a setting space for the hinge 16.

[0030] In addition, the edge portions 22a, 22b and the edge portions 22c, 22d are roughly parallel, which means that each edge portion 22a~22d is formed by a complete straight line and is completely parallel to each other, and of course, each edge portion 22a~22d has a slightly curved, concave and convex and is not completely parallel. Therefore, the outer shape of the first frame member 22 formed around by such edge portions 22a~22d is called a roughly rectangular shape as a concept including a square and a slightly deformed square.

[0031] Figure 2 Reference numeral 30 in the figure denotes a rubber leg fixed to an appropriate position of the bottom surface 12b. Figure 2 Reference numeral 27a in the figure denotes an air intake port for the cooling module 27, and is formed of, for example, a plurality of slits opened in the bottom surface 12b.

[0032] like Figure 2 As shown, the first frame member 22 is detachably connected to the second frame member 23 using a fastening portion 32 , a first engaging portion 34 , a second engaging portion 35 , a third engaging portion 36 , a suction portion 38 , and an auxiliary engaging portion 40 .

[0033] like Figure 2 and Figure 3A As shown, the fastening portion 32 is composed of a screw 42 and a threaded hole 43 for the screw 42 to be screwed. The fastening portion 32 is provided at, for example, three locations along the length direction (X direction) of the edge portion 22c of the first frame body member 22. The fastening portion 32 fastens one end (X1 side), the other end (X2 side) and the middle portion of the two ends relative to the second frame body member 23 in the length direction of the edge portion 22c. The configuration and the number of fastening portions 32 can be appropriately changed.

[0034] The screw 42 is inserted, for example, toward the Z1 direction into the protrusion 42a protruding toward the Z1 direction from the inner surface 22e of the first frame body part 22. The threaded hole 43 is, for example, formed on the inner peripheral surface of the protrusion 43a protruding toward the Z2 direction from the inner surface 23e of the second frame body part 23. Thus, the fastening part 32 can firmly fix the edge 22c of the first frame body part 22 to the second frame body part 23.

[0035] like Figure 2 and Figure 3A As shown, the first engaging portion 34 is composed of an engaging piece (first engaging piece) 44 and a receiving portion (first receiving portion) 45. The first engaging portion 34 is a hook-shaped latch-type engaging portion that connects the edge portion 22d of the first frame body component 22 to the second frame body component 23. The first engaging portion 34 is arranged on the inner surface 22e of one (X1 side) end 22d1 in the length direction of the edge portion 22d. That is, the first engaging portion 34 is located near the corner of the X1 side end and the Y1 side end of the first frame body component 22.

[0036] Figure 4 It is a perspective view in which the engaging piece 44 and its surroundings are enlarged. Figure 5 It is a perspective view in which the receiving portion 45 and its surrounding portion are enlarged. Fig. 6A It is a bottom view schematically showing a state immediately before the engaging piece 44 and the receiving portion 45 are engaged with each other. Figure 6B It means to make Fig. 6A The illustrated bottom view is a state in which the engaging piece 44 and the receiving portion 45 are engaged. Figure 7 It is an explanatory diagram schematically showing the engaged state of the first to third engaging portions 34 to 36 . Figure 7 It is a schematic diagram of the frame body 12 viewed from the bottom surface 12 b side in a state where the first frame body member 22 other than the engaging pieces 44 , 46 , 48 is omitted from illustration.

[0037] like Figure 4 , Fig. 6A as well as Figure 7 As shown, the engagement piece 44 is a hook-shaped portion provided on the inner surface 22e of one (X1 side) end 22d1 of the edge portion 22d and protruding toward the outside (Y1 side) of the edge portion 22d. The engagement piece 44 has a protruding piece 44a, a claw portion 44b, and an inclined surface 44c.

[0038] The protruding piece 44a is a plate piece that protrudes in the Z1 direction from the inner surface 22e of the first frame member 22. The claw portion 44b is bent from the front end of the protruding piece 44a and protrudes in the Y1 direction.

[0039] like Figure 4As indicated by the dot pattern in the figure, the inclined surface 44c has a structure obtained by cutting off a part of the front end surface (Y1 side end surface) of the claw portion 44b. The inclined surface 44c is a vertical plane along the Z direction, and gradually tilts from the Y2 side to the Y1 side as it tends to the X2 direction. That is, when the frame 12 is viewed from above, the inclined surface 44c gradually tilts from the edge portion 22c side to the edge portion 22d side as it tends to the X2 direction (first direction) from the side of one end 22d1 of the edge portion 22d toward the side of the other end 22d2. The claw portion 44b has such an inclined surface 44c at the front end. As a result, when the engaging piece 44 moves horizontally along the inclined direction (X2·Y2 direction) located in the middle of the X2 direction and the Y2 direction, the engaging state with the receiving portion 45 is easily released.

[0040] like Figure 5 , Fig. 6A as well as Figure 7 As shown, the receiving portion 45 is formed on the inner wall surface of the standing wall 23d of the second frame member 23 corresponding to the edge portion 22d, and is a portion for the hook-shaped engaging piece 44 to engage and disengage. The receiving portion 45 has a receiving surface 45a and an inclined surface 45b.

[0041] The vertical wall 23d forms a plate piece 45c protruding from the inner wall surface toward the Y2 direction. The receiving surface 45a is the Z1 side surface of the plate piece 45c. The receiving surface 45a functions as a stopper surface of the Z2 side surface of the claw portion 44b that stops the engaging piece 44 in the Z direction. The receiving portion 45 of this embodiment forms a recessed portion 45d that is recessed toward the Y1 side on the inner wall surface of the vertical wall 23d, thereby making the plate piece 45c and the receiving surface 45a protrude from the inner wall surface. The receiving portion 45 may also be formed by making the plate piece 45c protrude from the inner wall surface of the vertical wall 23d without providing the recessed portion 45d.

[0042] like Figure 5 As indicated by the dot pattern in the figure, the inclined surface 45b has a structure obtained by cutting off a part of the front end surface (Y2 side end surface) of the receiving portion 45 (plate 45c). The inclined surface 45b is a vertical plane along the Z direction, and gradually tilts from the Y2 side to the Y1 side as it tends to the X2 direction. That is, when the frame 12 is viewed from above, the inclined surface 45b gradually tilts from the edge portion 22c side to the edge portion 22d side as it tends to the X2 direction (first direction) from one end 22d1 side of the edge portion 22d toward the other end 22d2 side. The receiving portion 45 has such an inclined surface 45b at the front end. As a result, when the engaging piece 44 moves horizontally along the X2·Y2 direction, the engaging state of the receiving surface 45a with the claw portion 44b is easily released.

[0043] like Figure 2 and Figure 3AAs shown, the second engaging portion 35 is composed of an engaging piece (second engaging piece) 46 and a receiving portion (second receiving portion) 47. The second engaging portion 35 is a hook-shaped latch-type engaging portion that connects the edge portion 22d of the first frame body component 22 to the second frame body component 23. The second engaging portion 35 is arranged on the inner surface 22e of the other (X2 side) end 22d2 in the length direction of the edge portion 22d. That is, the second engaging portion 35 is located near the corner of the X2 side end and the Y1 side end of the first frame body component 22.

[0044] The second engagement portion 35 of the present embodiment has a shape that is symmetrical with respect to a plane (YZ plane) that is orthogonal to the longitudinal direction of the edge portion 22d (see Figure 2 and Figure 7 Therefore, the same reference numerals as those of the respective components of the engaging piece 44 and the receiving portion 45 constituting the first engaging portion 34 are used for the respective components of the engaging piece 46 and the receiving portion 47, and detailed description thereof is omitted.

[0045] That is, the engaging piece 46 also has a protruding piece 44a, a claw portion 44b and an inclined surface 44c. The inclined surface 44c of the engaging piece 46 is a vertical plane along the Z direction, and gradually tilts from the Y2 side to the Y1 side as it tends to the X1 direction. That is, when the frame 12 is viewed from above, the inclined surface 44c of the engaging piece 46 gradually tilts from the edge portion 22d side to the edge portion 22c side as it tends to the X2 direction (first direction) from one end 22d1 side of the edge portion 22d toward the other end 22d2 side. Similarly, the receiving portion 47 also has a receiving surface 45a and an inclined surface 45b. The inclined surface 45b of the receiving portion 47 is a vertical plane along the Z direction, and gradually tilts from the Y2 side to the Y1 side as it tends to the X1 direction. That is, when observing the frame 12 from above, with the directions of the various parts in the first frame member 22 as a reference, the inclined surface 45b of the receiving portion 47 gradually inclines from the edge portion 22d side toward the edge portion 22c side as it moves in the X2 direction (first direction) from the side of one end 22d1 of the edge portion 22d toward the side of the other end 22d2.

[0046] Thus, the second engaging portion 35 also has inclined surfaces 44c and 45b at the front ends of the engaging piece 46 and the receiving portion 47. Thus, when the engaging piece 46 of the second engaging portion 35 moves horizontally in the inclined direction (X1·Y2 direction) located in the middle of the X1 direction and the Y2 direction in a plan view, the engaging state with the receiving portion 47 is easily released.

[0047] like Figure 2 and Figure 3AAs shown, the third engaging portion 36 is composed of an engaging piece (third engaging piece) 48 and a receiving portion (third receiving portion) 49. The third engaging portion 36 is a hook-shaped latch-type engaging portion that connects the edge portion 22d of the first frame body component 22 relative to the second frame body component 23. The third engaging portion 36 is arranged on the inner surface 22e between the upper end portions 22d1 and 22d2 in the length direction of the edge portion 22d. The third engaging portion 36 of the present embodiment is arranged in a pair along the edge portion 22d. The third engaging portion 36 can also be provided with one or more than three.

[0048] The engaging piece 48 is Figure 4 The illustrated engaging piece 44 does not have a structure with an inclined surface 44c. That is, the engaging piece 48 has the same protruding piece 44a and claw portion 44b as the engaging piece 44. However, the front end surface of the claw portion 44b of the engaging piece 48 is not cut off. Therefore, a plane 48a (see FIG. 1 ) is provided on the Y1 side end surface of the engaging piece 48 along the vertical plane in the Z direction and along the length direction (X direction) of the edge portion 22d. Figure 7 ).

[0049] The receiving portion 49 is Figure 5 The receiving portion 45 shown in the figure does not have a structure with an inclined surface 45b. That is, the receiving portion 49 has the same receiving surface 45a and plate 45c as the receiving portion 45. However, the front end surface of the plate 45c of the receiving portion 49 is not cut. Therefore, a plane 49a (see FIG. 1 ) is provided on the Y2 side end surface of the receiving portion 49 along the vertical plane of the Z direction and along the longitudinal direction (X direction) of the edge portion 22d and the vertical wall 23d. Figure 7 ).

[0050] like Figure 2 and Figure 3A As shown, the adsorption part 38 is composed of a first adsorption body 38a and a second adsorption body 38b that can be adsorbed to each other. The adsorption part 38 uses magnetic force to fix the left and right edge parts 22a and 22b of the first frame part 22 to the second frame part 23 respectively. For the adsorption bodies 38a and 38b, one side can be composed of a magnet, and the other side can be composed of a magnet or a magnetic body such as steel that can be adsorbed to the magnet on one side. The adsorption bodies 38a and 38b of this embodiment are both magnets.

[0051] The first adsorbent 38a is fixed to the inner surface 22e of the middle portion in the length direction (Y direction) of the left and right edge portions 22a, 22b of the first frame body part 22. The second adsorbent 38b is fixed to the inner surface 23e of the second frame body part 23 at a position overlapping with the first adsorbent 38a in the Z direction. The adsorbent portion 38 is disposed in the middle portion of the edge portions 22a, 22b where the fastening portion 32 and the engaging portions 34 to 36 are not disposed, that is, near the center in the Y direction, to suppress shaking and the generation of gaps between the frame body parts 22, 23. For example, in a case where the first frame body part 22 has sufficient rigidity, the adsorbent portion 38 may be omitted.

[0052] like Figure 2 and Figure 3A As shown, the auxiliary engaging portion 40 is composed of an elastic engaging piece 50 and a receiving portion 51. The auxiliary engaging portion 40 is a hook-shaped latch-type engaging portion that connects the left and right edge portions 22a, 22b of the first frame body member 22 to the second frame body member 23. The auxiliary engaging portion 40 is provided on the inner surface 22e of the middle portion in the length direction (Y direction) of the edge portions 22a, 22b, and is adjacent to the adsorption portion 38.

[0053] The elastic snap-fitting piece 50 has a claw protruding from the front end of the protruding piece protruding from the inner surface 22e toward the Z1 direction toward the outer side of the edge portion 22a, 22b. The claw of the elastic snap-fitting piece 50 of the edge portion 22a protrudes toward the X1 direction. The claw of the elastic snap-fitting piece 50 of the edge portion 22b protrudes toward the X2 direction. The receiving portion 51 is formed on the inner wall surface of the vertical wall 23a, 23b of the second frame body component 23 corresponding to the edge portion 22a, 22b, and is a part for the claw of the elastic snap-fitting piece 50 to engage and disengage. The elastic snap-fitting piece 50 is a hook-shaped portion that is relatively small than the above-mentioned snap-fitting pieces 44, 46, 48. The protruding piece of the elastic snap-fitting piece 50 can be elastically deformed relative to the X direction. Therefore, the elastic snap-fitting piece 50 can be easily engaged and disengaged along the Z direction relative to the receiving portion 51.

[0054] The auxiliary engagement portion 40 is provided in the middle of the edge portions 22a and 22b similarly to the adsorption portion 38 to suppress the occurrence of play and gap between the frame members 22 and 23. For example, the auxiliary engagement portion 40 may be omitted when the first frame member 22 has sufficient rigidity.

[0055] However, in the electronic device 10 of the present embodiment, although it is rare, the battery 28 composed of, for example, a lithium polymer battery may sometimes swell to 400 to 500% or more in volume during use due to manufacturing defects or the like (see Figure 3B ).exist Figure 2 and Figure 7, the expansion portion 28a of the battery 28 is schematically illustrated in a manner surrounded by a dot-dash line. Such a defective battery 28 needs to be replaced. However, when the battery 28 expands, the first frame member 22 is pressed from the inside, so the damage of the first frame member 22 becomes a problem. Therefore, the electronic device 10 is particularly equipped with the above-mentioned engaging portions 34 and 35, thereby suppressing the damage of the first frame member 22 when the battery 28 expands, and smoothly removing and replacing the battery 28 from the second frame member 23.

[0056] Next, the operation and effects of the housing 12 when the battery 28 expands will be described.

[0057] like Figure 2 and Figure 3A As shown, the frame 12 is in a state where the frame parts 22 and 23 are connected, the screw 42 is fastened to the threaded hole 43 at the fastening part 32, the adsorbents 38a and 38b are adsorbed and fixed at the adsorption part 38, and the elastic engagement piece 50 is engaged with the receiving part 51 at the auxiliary engagement part 40. Figure 2 , Figure 3A , Figure 6B as well as Figure 7 As shown in the engaging pieces 44, 46, 48 shown in the figure, the engaging pieces 44, 46, 48 of the engaging parts 34 to 36 are respectively engaged with the receiving parts 45, 47, 49. As a result, the first frame member 22 is firmly connected to the second frame member 23 without loosening.

[0058] In this state, if the battery 28 swells due to a defect or the like, Figure 3B As shown, the expansion portion 28a pushes the inner surface 22e of the first frame member 22 upward in the Z2 direction (see Figure 3B The battery 28 is located in the housing 12 near the Y1 side (see also Figure 2 ). Therefore, the expansion portion 28a pushes up the inner surface 22e at a position near the center of the first frame member 22 in the X direction and closer to the edge portion 22d on the Y1 side than the edge portion 22c on the Y2 side. Figure 7 As shown by the four arrows in the figure, the first frame member 22 is elastically deformed in a manner that the portion overlapping with the expansion portion 28a in the Z direction is expanded in a dome-like or tent-like manner as the top of the roof. As a result, the edge portion 22c of the first frame member 22 moves in the Y2 direction, and the end portion 22d1 and its surroundings also move toward the X2 side, and the end portion 22d2 and its surroundings also move toward the X1 side.

[0059] Therefore, in the first engagement portion 34 near the end 22d1, the engagement piece 44 moves in the oblique direction (X2·Y2 direction). In the second engagement portion 35 near the end 22d2, the engagement piece 46 moves in the oblique direction (X1·Y2 direction). On the other hand, in the third engagement portion 36 located between the end portions 22d1 and 22d2, the engagement piece 48 moves in the substantially straight direction (Y2 direction).

[0060] Moreover, for example, when the expansion rate of the battery 28 exceeds a set value, for example, exceeds 100% to 150%, Figure 3B and Figure 7 As shown in the engaging pieces 44, 46, 48 drawn in the figure, the engaging state of each engaging portion 34 to 36 is released. That is, the engaging state of the engaging pieces 44, 46, 48 and the receiving portions 45, 47, 49 is released, and the edge portion 22d becomes free (refer to Figure 3B As a result, the edge portion 22d of the first frame member 22 separates from the second frame member 23 and is lifted toward the Z2 side (see arrow B in FIG. 1 ). Figure 3B At this time, the fixation of the adsorbents 38a and 38b fixed only by magnetic force is also released. In addition, in the auxiliary engaging portion 40, the elastic engaging piece 50 is also pulled toward the central side of the first frame member 22 by the expansion portion 28a in the X direction and the engaging state with the receiving portion 51 is released.

[0061] On the other hand, since the fastening portion 32 is fixed by the screw 42, the edge portion 22c remains connected to the second frame body member 23. As a result, the first frame body member 22 is in an open state in which the edge portion 22d close to the battery 28 and a portion of the Y1 side of the left and right edge portions 22a and 22b are separated from the second frame body member 23 and lifted to the Z2 side.

[0062] Therefore, the user can quickly recognize that the first frame member 22 is detached due to the expansion of the battery 28. Therefore, the maintenance operator can completely remove the first frame member 22 from the second frame member 23 by only removing the screw 42 of the fastening portion 32, and can easily replace the battery 28. In this way, when the battery 28 expands, the edge portion 22d of the first frame member 22 and its surrounding portion of the electronic device 10 are smoothly detached from the second frame member 23, so that the first frame member 22 can be prevented from being plastically deformed or damaged by excessive force from the expansion portion 28a.

[0063] Here, refer to Figure 8 and Fig. 9 The operation and effect of the first engaging portion 34 (embodiment) having the inclined surfaces 44c and 45b are described in more detail by comparing them with the engaging portion 52 (comparative example) having a conventional general structure. The operation and effect of the second engaging portion 35 are also substantially the same as those of the first engaging portion 34.

[0064] Figure 8 It is an explanatory diagram showing a change in the engagement state with the receiving portion 45 when the engagement piece 44 of the first engagement portion 34 moves in the oblique direction (X2·Y2 direction). Fig. 9 Yes means Figure 8 1 and 2 , which are explanatory diagrams showing changes in the engagement state of the engagement piece 44 of the engagement portion 52 according to the comparative example of the first engagement portion 34 shown in FIG. 3 with the receiving portion 45 when the engagement piece 44 of the engagement portion 52 moves in the oblique direction (X2·Y2 direction).

[0065] Fig. 9 The engaging portion 52 of the comparative example shown is Figure 8 The illustrated embodiment has a structure in which the inclined surfaces 44 c and 45 b of the first engagement portion 34 are replaced with the same flat surfaces 48 a and 49 a as those of the third engagement portion 36 .

[0066] exist Figure 8 In the first engaging portion 34 shown, when the engaging piece 44 moves in the inclined direction (X2·Y2 direction) as the battery 28 expands, the engaging state between the claw portion 44b and the receiving surface 45a is easily released. This is because, due to the inclined surfaces 44c and 45b, the action amount (locking distance) of the claw portion 44b and the receiving surface 45a in the direction along the relative movement direction of the engaging piece 44 and the receiving portion 45 (X2·Y2 direction) is small. Therefore, in the first engaging portion 34, compared with the third engaging portion 36 located near the center of the edge portion 22d, the moving distance of the engaging piece 44 in the Y2 direction is smaller, but due to the shortest distance in design, the claw portion 44b is easily disengaged from the receiving surface 45a. In addition, the second engaging portion 35 also smoothly disengages the engaging piece 46 from the receiving portion 47 when the battery 28 expands through the same action (see also). Figure 7 ).

[0067] On the other hand, Fig. 9 In the engaging portion 52 of the comparative example shown in FIG. 1 , even if the engaging piece 44 moves in the oblique direction, Figure 8 Even when the distance is the same as the situation shown, the claw portion 44b cannot easily disengage from the receiving surface 45a. This is because the claw portion 44b having the planes 48a and 49a and the receiving surface 45a have a large action amount (stopping distance) in the direction along the relative movement direction of the engaging piece 44 and the receiving portion 45 (X2·Y2 direction). Therefore, in the engaging portion 52, the claw portion 44b of the engaging piece 44 with a smaller moving distance in the Y2 direction cannot easily disengage from the receiving surface 45a compared to the third engaging portion 36 located near the center of the edge portion 22d. In this way, Figure 8 The first engaging portion 34 of the embodiment shown is Fig. 9Compared with the engaging portion 52 of the comparative example shown, when the engaging piece 44 is pulled in the inclined direction when the battery 28 expands, it can be more smoothly separated from the receiving portion 45.

[0068] As described above, for the electronic device 10 of the present embodiment, the battery 28 is arranged in the frame 12 at a position closer to the edge portion 22d side than the edge portion 22c side. The end faces of the engaging piece 44 provided at one end 22d1 of the edge portion (second edge portion) 22d of the first frame body member 22 and the receiving portion 45 that is disengaged therefrom are provided with inclined surfaces (first inclined surfaces) 44c and 45b that gradually tilt from the edge portion 22c side to the edge portion 22d side as they approach the other end 22d2 side. Similarly, the end faces of the engaging piece 46 provided at the other end 22d2 of the edge portion 22d of the first frame body member 22 and the receiving portion 47 that is disengaged therefrom are provided with inclined surfaces (second inclined surfaces) 44c and 45b that gradually tilt from the edge portion 22d side to the edge portion 22c side as they approach the end 22d2 side from the end 22d1 side.

[0069] Therefore, even when the battery 28 expands due to a defect and presses the first frame body part 22, the electronic device 10 smoothly releases the engagement state of the edge 22d located near the battery 28 to the engagement pieces 44, 46 and the receiving parts 45, 47 of the second frame body part 23. In other words, when the frame 12 expands to an expansion rate above the specified value, the connection state between the frame body parts 22 and 23 is released, and the edge 22d side opens the mouth. As a result, it is possible to suppress the first frame body part 22 from being damaged by excessive force from the expanded battery 28, such as cracks, and it is possible to suppress the cost and effort of maintenance. At this time, the edge 22c is fixed by the fastening part 32 of the screw 42. Thus, the fastening part 32 supports the first frame body part 22 even after the above-mentioned opening, so that the first frame body part 22 can be prevented from falling accidentally, and the handling property is improved.

[0070] In the present embodiment, the engaging piece 44 is disposed at a position protruding from the end (side) of the battery 28 on the X1 side based on the longitudinal direction of the edge portion 22d and at a position not overlapping the battery 28 with respect to the Y direction (see Figure 2 and Figure 7 ). Similarly, the engaging piece 46 is arranged at a position exposed from the end (side) of the X2 side of the battery 28 based on the longitudinal direction of the edge portion 22d, and is located at a position that does not overlap with the battery 28 with respect to the Y direction. Therefore, when the engaging pieces 44 and 46 are pulled closer by the first frame member 22 that is lifted when the battery 28 expands, there is a tendency that the amount of movement in the X direction is greater than the amount of movement in the Y2 direction. Therefore, for example, Fig. 9In the illustrated engaging portion 52, when the amount of movement in the X direction is large, the engaging state is difficult to be further released. In this regard, the engaging portions 34 and 35 of the present embodiment are provided with inclined surfaces 44c and 45b, so that the engaging state is smoothly released even when the amount of movement in the X direction is large.

[0071] In addition, the claws 44b and the receiving surface 45a of each engaging portion 34, 35 have inclined surfaces 44c, 45b, so that the engaging state of each other is easily released when moving in the above-mentioned inclined direction, and in the usual connection state of the frame parts 22, 23, there is a sufficient amount of action (stop distance) in the Y direction. Therefore, the engaging portions 34, 35 can suppress the engaging state from accidentally disengaging when the frame 12 is subjected to an impact such as falling, for example.

[0072] On the other hand, the third engaging portion 36 located between the ends 22d1 and 22d2 of the edge portion 22d is arranged at a position that does not protrude from the ends (side faces) on the X1 and X2 sides of the battery 28 based on the longitudinal direction of the edge portion 22d, and is located at a position overlapping with the battery 28 with respect to the Y direction (see Figure 2 and Figure 7 ). Therefore, when the engaging piece 48 of the third engaging portion 36 is pulled closer by the first frame member 22 lifted when the battery 28 expands, it hardly moves in the X direction, but mainly moves in the Y2 direction. Therefore, the third engaging portion 36 is configured to have planes 48a and 49a along the XZ direction instead of the inclined surfaces 44c and 45b, so that the engaging state is smoothly released when the battery 28 expands. Of course, since such a third engaging portion 36 also has a sufficient amount of action (stop distance) in the Y direction, it is possible to prevent the engaging state from accidentally disengaging when the frame 12 is subjected to an impact such as falling.

[0073] In addition, the present invention is not limited to the above-mentioned embodiment, and it is of course possible to freely change it within the scope not departing from the gist of the present invention.
