[Embodiments for Carrying Out the Invention]

[0015] [First Embodiment] Hereinafter, embodiments of the electronic device 1 will be described in detail with reference to the accompanying drawings. The configurations of the embodiments described below, as well as the operations and results (effects) brought about by these configurations, are merely examples and are not limited to the following description. In this specification, ordinal numbers are used only for distinguishing parts and members and do not indicate order or priority.

[0016] First, the outline and structure of the electronic device 1 according to the first embodiment will be described with reference to Figures 1 and 2. Figure 1 is a perspective view showing the electronic device 1 according to the first embodiment. Figure 2 is a bottom view showing the bottom cover 122 of the electronic device 1 according to the first embodiment.

[0017] As shown in Figures 1 and 2, the electronic device 1 comprises a main body 12 having a top cover 121 and a bottom cover 122. Four screws 18 secure the top cover 121 and the bottom cover 122. The top cover 121 is an example of a first component. The bottom cover 122 is an example of a second component.

[0018] In the following figures, for convenience, three mutually orthogonal directions are defined. The width direction of the electronic device 1 is defined as the X-axis direction, the depth direction of the electronic device 1 is defined as the Y-axis direction, and the thickness direction of the electronic device 1 is defined as the Z-axis direction. The X-axis direction may also be referred to as the left-right direction. The Y-axis direction may also be referred to as the front-back direction. The Z-axis direction may also be referred to as the up-down direction. Note that the expressions indicating directions such as front-back, left-right, up-down in this embodiment are for convenience only and do not limit the position, orientation, or manner of use of the electronic device 1.

[0019] Electronic device 1 is, for example, a widely used portable personal computer (a so-called notebook computer). Electronic device 1 may also be, for example, a desktop personal computer or a tablet. The top cover 121 and the bottom cover 122 are fitted together and fixed in the Z-axis direction to form a roughly rectangular box shape.

[0020] The top cover 121 and bottom cover 122 are made of metal, for example. Generally, a metal housing is more rigid than a resin housing, provided they have the same shape and thickness. Due to the above structure, the electronic device 1 can be made thinner than an electronic device in which the top cover 121 and bottom cover 122 are made of resin.

[0021] Next, the internal structure of the top cover 121 will be described with reference to Figures 3 to 6. Figure 3 is a bottom view of the top cover 121 as seen from the bottom side of the electronic device 1 according to the first embodiment. Figure 4 is an enlarged perspective view of part F4 in Figure 3 in the electronic device 1 according to the first embodiment. Figure 5 is an enlarged perspective view of part F5 in Figure 3 in the electronic device 1 according to the first embodiment. Figure 6 is an enlarged perspective view of part F6 in Figure 3, with the fourth part 1212b omitted.

[0022] As shown in Figure 3, mating positions C1, C2, C3, and C4 are provided on the back side of the top cover 121. As shown in Figure 4, a wire member 14, a receiving part 1211, and a fixing part 1212 are arranged at part F4 (matting position C2) of the top cover 121. The mating positions C1, C3, and C4 have a similar configuration.

[0023] The wire member 14 is disposed inside the top cover 121. As shown in Figures 4, 5, and 6, the wire member 14 is formed in a substantially cylindrical shape. The wire member 14 is formed in a U-shape. The wire member 14 may also be formed in an L-shape, for example. The wire member 14 has a first portion 141, a second portion 142, and a curved portion 143.

[0024] The first part 141 extends in the Y-axis direction. The second part 142 is integrally molded with the first part 141. The second part 142 extends in the Y-axis direction. The second part 142 is positioned closer to the end of the top cover 121 than the first part 141. The curved portion 143 connects the first part 141 and the second part 142. The curved portion 143 is formed in a substantially arc shape. The first part 141 and the second part 142 form a U-shape or L-shape.

[0025] The receiving portion 1211 is formed inside the upper cover 121. The receiving portion 1211 is formed in a substantially rectangular parallelepiped shape. The receiving portion 1211 extends in the Y-axis direction. The receiving portion 1211 protrudes in the -Z direction from the surface 1213 of the upper cover 121. The receiving portion 1211 is an integrated structure with the upper cover 121. The first portion 141 is in contact with the receiving portion 1211 in the X-axis direction. The receiving portion 1211 is an example of a first protrusion.

[0026] The fixing portion 1212 is formed inside the top cover 121. The fixing portion 1212 protrudes in the -Z direction from the surface 1213 of the top cover 121. The wire member 14 is fitted to the fixing portion 1212 in a bent state. The fixing portion 1212 is an example of a fitting portion.

[0027] The fixed portion 1212 has a third portion 1212a and a fourth portion 1212b. The third portion 1212a is integrally molded with the top cover 121. The third portion 1212a extends from the surface 1213 of the top cover 121 in the -Z direction. The third portion 1212a is formed to fill the gap between the first portion 141 and the second portion 142.

[0028] The wire member 14 is fixed to the fixing part 1212 by being inserted in the -Y direction relative to the third part 1212a such that the third part 1212a fits into the space between the first part 141 and the second part 142.

[0029] At this time, there is a small gap (clearance) between the third portion 1212a and the wire member 14 on the XY plane. This gap allows for a displacement of the wire member 14 relative to the fixing portion 1212, improving the degree of freedom of the wire member 14's position relative to the fixing portion 1212. If there is no such gap, the wire member 14 will be more firmly attached to the fixing portion 1212, and will be more securely fixed to the fixing portion 1212. The third portion 1212a can also be formed to increase the gap between it and the wire member 14, thereby intentionally creating a structure that causes some looseness in the fixing portion 1212 relative to the wire member 14.

[0030] The fourth portion 1212b is integrally molded with the third portion 1212a and covers at least a portion of the first portion 141 and the second portion 142. The fourth portion 1212b extends in the Y-axis direction. The fourth portion 1212b can also be formed to increase the gap between it and the wire member 14, thereby intentionally creating a structure that causes rattle of the fixing portion 1212 relative to the wire member 14.

[0031] The wire member 14, the receiving portion 1211, and the fixing portion 1212 are arranged in the same configuration at each of the mating positions C1, C2, C3, and C4. Note that the fourth portion 1212b is omitted in Figure 6.

[0032] The wire member 14 is an elastic body that elastically deforms and generates an elastic force when an external force is applied to the first portion 141 or the second portion 142. The wire member 14 uses its own elastic force to press the first portion 141 against the receiving portion 1211 and the second portion 142 against the claw portion 1221, thereby fixing the top cover 121 and the bottom cover 122 (see Figures 4 and 10).

[0033] Next, the internal structure of the bottom cover 122 will be described with reference to Figures 7 to 9. Figure 7 is a top view showing the bottom cover 122 as seen from the top side of the electronic device 1 according to the first embodiment.

[0034] As shown in Figure 7, the inside of the bottom cover 122 is provided with mating positions D1, D3, D4, and D2, respectively, from the -X direction side.

[0035] Figure 8 is a perspective view showing an enlarged view of section F8 in Figure 7 of the electronic device 1 according to the first embodiment. The bottom cover 122 is a cover that is paired with the top cover 121. As shown in Figure 8, a claw portion 1221 is provided at section F8 (fitting position D2) of the bottom cover 122. The same configuration is used for the fitting position D1.

[0036] The claw portion 1221 is a member that engages with a bent wire member 14 positioned at a corresponding location. By engaging with the wire member 14 positioned at a corresponding location, the claw portion 1221 fixes the bottom cover 122 to the top cover 121. The claw portion 1221 is an example of a second protrusion.

[0037] Furthermore, the claw portion 1221 has a second flat portion 1221a. The second flat portion 1221a has a surface that is formed flat in the XY plane. The second flat portion 1221a engages with the second portion 142 of the wire member 14.

[0038] The claw portion 1221 protrudes in the -X direction from the contact portion 1224 of the bottom cover 122 as it moves toward the direction of engagement with the top cover 121. Here, the direction in which the claw portion 1221 and the top cover 121 engage is the direction in which the top cover 121 engages with the bottom cover 122, which is the -Z direction. Also, at the engagement position D1, the direction in which the claw portion 1221 protrudes is the +X direction.

[0039] Figure 9 is a perspective view showing an enlarged view of part F9 in Figure 7 of the electronic device 1 according to the first embodiment. As shown in Figure 9, a claw portion 1221 is provided at part F9 (fitting position D4) of the bottom cover 122. The same configuration is used for fitting position D3. The claw portion 1221 at fitting positions D3 and D4 protrudes in the -Y direction.

[0040] Next, the engagement of the wire member 14 and the claw portion 1221 will be described with reference to Figure 10. Figure 10 is a perspective view showing the wire member 14 and the claw portion 1221 in the electronic device 1 according to the first embodiment.

[0041] As shown in Figure 10, when the wire member 14 and the claw portion 1221 are engaged, the second portion 142 of the wire member 14 is in contact with the contact portion 1224 of the claw portion 1221. Here, the wire member 14, with its own elastic force, presses the first portion 141 against the receiving portion 1211 and the second portion 142 against the contact portion 1224 of the claw portion 1221, thereby fixing the top cover 121 and the bottom cover 122. Note that the receiving portion 1211 is not shown in Figure 10.

[0042] The wire member 14 presses its first portion 141 against the receiving portion 1211 with elastic force, and the resulting reaction generates an elastic force that presses its second portion 142 against the contact portion 1224 of the claw portion 1221. As a result, the contact portion 1224 (bottom cover 122) is fixed in place by the wire member 14 pressing against the second portion 142.

[0043] Specifically, the receiving portion 1211 (top cover 121) is fixed by the wire member 14 pressing its first portion 141 in the +X direction, and the contact portion 1224 (bottom cover 122) is fixed by the wire member 14 pressing its second portion 142 in the -X direction.

[0044] In other words, the receiving portion 1211 and the contact portion 1224 are pressed against each other in opposite directions by the wire member 14 in the X-axis direction. In this way, the top cover 121 and the bottom cover 122 are fitted together and fixed in place.

[0045] The wire member 14 is, for example, a metal elastic body. Also, as described above, in this embodiment, the top cover 121 and the bottom cover 122 are made of metal. Therefore, the top cover 121, the bottom cover 122 and the wire member 14 are electrically conductive. Furthermore, the top cover 121 and the bottom cover 122 are fitted together via the wire member 14. This structure allows the electronic device 1 to ensure electrical conductivity between the covers.

[0046] Next, with reference to Figure 11, the process by which the wire member 14 engages with the claw portion 1221 will be described. Figure 11 is a diagram showing the wire member 14, fixing portion 1212, and claw portion 1221 in the electronic device 1 according to the first embodiment along the line F11-F11 in Figure 1, and is a diagram illustrating the process by which the wire member 14 engages with the claw portion 1221.

[0047] In Figures 11(a) and (b), first, the top cover 121 is positioned relative to the bottom cover 122 and moved in the -Z direction. Then, in Figure 11(c), the second portion 142 of the wire member 14 is inserted into the bottom cover 122 in the -X and -Z directions, following the shape of the claw portion 1221. At this time, the second portion 142 of the wire member 14 is bent in the -X direction, and an elastic force is generated in the +X direction.

[0048] Then, in Figure 11(d), as the second portion 142 of the wire member 14 is moved in the -Z direction, it moves in the +X direction due to elastic force. Subsequently, in Figure 11(e), the wire member 14 presses the second portion 142 against the contact portion 1224 of the bottom cover 122 in the +X direction due to elastic force. At this time, the second portion 142 of the wire member 14 is in contact with the protruding portion of the claw portion 1221 in the Y-axis direction. As a result, the claw portion 1221 generates a mating force with the wire member 14. This mating force becomes stronger as the contact area between the second portion 142 and the protruding portion of the claw portion 1221 increases. Through the above procedure, the wire member 14 mates with the claw portion 1221.

[0049] Figure 12 is a perspective view showing a battery unit 16 housed in the electronic device 1 according to the first embodiment. As shown in Figure 12, the top cover 121 of the electronic device 1 can be removed by releasing the engagement between the wire member 14 and the claw portion 1221. This allows the user to access the battery unit 16, which is located inside the main body 12, more easily than in conventional designs.

[0050] The electronic device 1 of the above embodiment comprises a top cover 121, a bottom cover 122, and a wire member 14. The top cover 121 has a receiving portion 1211 and a fixing portion 1212. The bottom cover 122 has a claw portion 1221 and is paired with the top cover 121. The wire member 14, when bent, fits into the fixing portion 1212 and has a first portion 141 and a second portion 142. The first portion 141 abuts against the receiving portion 1211. The second portion 142 abuts against the claw portion 1221. The wire member 14, by its own elastic force, presses the first portion 141 against the receiving portion 1211 and the second portion 142 against the claw portion 1221, thereby fixing the top cover 121 and the bottom cover 122.

[0051] In the above configuration, the wire member 14 has a first portion 141 that fits into the fixing portion 1212 in a bent state and contacts the receiving portion 1211, and a second portion 142 that contacts the claw portion 1221. Furthermore, the wire member 14 uses its own elastic force to press the first portion 141 against the receiving portion 1211 and the second portion 142 against the claw portion 1221 (contact portion 1224), thereby fixing the top cover 121 and the bottom cover 122.

[0052] With this configuration, the electronic device 1 can fix the top cover 121 and the bottom cover 122 by the elastic force of the wire member 14, resulting in a cover with high aesthetic appeal, ease of assembly, and ease of disassembly.

[0053] Furthermore, in this embodiment, the first portion 141 and the second portion 142 form a U-shaped or L-shaped part.

[0054] According to the above configuration, the wire member 14 is bent such that the first portion 141 and the second portion 142 form a U-shape or L-shape. As a result, the first portion 141 and the second portion 142 can generate elastic force when an external force is applied. Consequently, the electronic device 1 can fix the top cover 121 and the bottom cover 122 by the elastic force of the wire member 14.

[0055] Furthermore, in this embodiment, the bottom cover 122 has a claw portion 1221 that protrudes in the direction toward engaging with the top cover 121 and engages with the bent wire member 14.

[0056] According to the above configuration, the bottom cover 122 has a claw portion 1221 that engages with the bent wire member 14. The claw portion 1221 protrudes in the direction toward which the top cover 121 and the bottom cover 122 engage.

[0057] Here, when the wire member 14 and the claw portion 1221 are engaged, first, the top cover 121 is pushed in the direction that engages with the bottom cover 122, causing the wire member 14 to be gradually bent by the protruding claw portion 1221, and the elastic force generated when it is bent pushes back against the claw portion 1221. At this point, a force is generated on the wire member 14 that presses down on the claw portion 1221 (contact portion 1224).

[0058] Then, as the top cover 121 is continuously pushed in the direction that it engages with the bottom cover 122, and the wire member 14 exceeds the protrusion of the claw portion 1221, the claw portion 1221 engages with the wire member 14, with the protrusion acting as a catch. At this time, the wire member 14 is bent, generating an elastic force that presses against the claw portion 1221 (contact portion 1224).

[0059] In other words, the wire member 14 engages with the claw portion 1221 (contact portion 1224) while generating a force (elastic force) that presses against the claw portion 1221. As a result, the wire member 14 can suppress rattling relative to the bottom cover 122. Consequently, the electronic device 1 can suppress rattling when the top cover 121 and the bottom cover 122 are fixed together.

[0060] Furthermore, in this embodiment, the top cover 121 has a fixing portion 1212 which includes a third portion 1212a formed to fill the gap between the first portion 141 and the second portion 142, and a fourth portion 1212b integrally molded with the third portion 1212a and covering at least a portion of the first portion 141 and the second portion 142.

[0061] According to the above configuration, the third portion 1212a and the fourth portion 1212b of the fixing portion 1212 are formed to fill the gap between the first portion 141 and the second portion 142, thereby reducing the gap between the first portion 141 and the second portion 142 and suppressing rattling of the fixing portion 1212 relative to the wire member 14.

[0062] Furthermore, by forming the third portion 1212a and the fourth portion 1212b in such a way that a gap is created between them and the first portion 141 and the second portion 142, it is possible to intentionally cause rattling of the fixing portion 1212 to the wire member 14.

[0063] Furthermore, in this embodiment, the top cover 121, the bottom cover 122, and the wire member 14 are made of metal.

[0064] According to the above configuration, the top cover 121, the bottom cover 122, and the wire member 14 are electrically conductive. Furthermore, the top cover 121 and the bottom cover 122 are interlocked via the wire member 14. This structure allows the electronic device 1 to ensure electrical conductivity between the top cover 121 and the bottom cover 122.

[0065] Furthermore, in this embodiment, the third portion 1212a and the fourth portion 1212b are arranged to have clearance with respect to the first portion 141 and the second portion 142.

[0066] According to the above configuration, the third portion 1212a and the fourth portion 1212b are formed to have a clearance with respect to the first portion 141 and the second portion 142, thereby intentionally causing rattling of the fixing portion 1212 to the wire member 14, i.e., rattling of the upper cover 121.

[0067] [Example 1] Next, with reference to Figure 13, a modified example 1 of the electronic device 1 according to the first embodiment will be described. Figure 13 is a perspective view showing the wire member 14A and the claw portion 1221 in a modified example 1 of the electronic device 1 according to the first embodiment. In the following description, components similar to those in the first embodiment are denoted by the same reference numerals, and their descriptions are omitted.

[0068] In the electronic device 1 of modified example 1, the second portion 142A of the wire member 14A has a first flat portion 1421. The first flat portion 1421 has a surface that is formed flat in the XY plane. The first flat portion 1421 engages with the claw portion 1221.

[0069] When the second portion 142A of the wire member 14A and the claw portion 1221 are engaged, the flat surface of the first flat portion 1421 abuts against the second flat portion 1221a. That is, the second portion 142A of the wire member 14A and the claw portion 1221 abut each other on their flat surfaces.

[0070] With this configuration, the second portion 142A of the wire member 14A and the claw portion 1221 can generate a stronger mating force than the wire member 14 and claw portion 1221 in the first embodiment. In other words, the electronic device 1 in the modified example 1 can more tightly mat the top cover 121 and the bottom cover 122.

[0071] In the electronic device 1 of the above embodiment, the wire member 14A has a first flat portion 1421 that engages with the claw portion 1221, and the claw portion 1221 has a second flat portion 1221a that engages with the first flat portion 1421.

[0072] According to the above configuration, the wire member 14A and the claw portion 1221 are locked together and fixed by the first flat portion 1421 and the second flat portion 1221a coming into contact with each other. Here, the locking force between the wire member 14A and the claw portion 1221 can be adjusted by changing the angle of the first flat portion 1421 and the second flat portion 1221a with respect to the direction in which the wire member 14A is pushed against the claw portion 1221.

[0073] [Differentiation 2] Next, a modified example 2 of the electronic device 1 according to the first embodiment will be described with reference to Figures 14 to 16. Figure 14 is a cross-sectional view showing the wire member 14 and fixing part 1212 of the electronic device 1 according to the first embodiment along the line F14-F14 in Figure 4. Figure 15 is a perspective view showing the wire member 14 and fixing part 1212A in the modified example 2 of the electronic device 1 according to the first embodiment. Figure 16 is a cross-sectional view showing the wire member 14 and fixing part 1212A in the modified example 2 of the electronic device 1 according to the first embodiment along the line F16-F16 in Figure 15. In the following description, components similar to those in the first embodiment will be denoted by the same reference numerals, and their descriptions will be omitted.

[0074] Figure 14 is a cross-sectional view showing the wire member 14 and fixing portion 1212 of the first embodiment described above. As shown in Figure 14, the cross-section of the wire member 14 is circular, and the cross-section of the fixing portion 1212 around the wire member 14 is substantially rectangular.

[0075] In contrast, in the modified example 2, as shown in Figures 15 and 16, the cross-section of the wire member 14 is circular, while the cross-section of the fixing portion 1212A around the wire member 14 is substantially elliptical. Furthermore, the third portion 1212a2 and the fourth portion 1212b2 of the fixing portion 1212A cover the first portion 141 and the second portion 142 of the wire member 14 on the XZ plane.

[0076] This structure allows the fixing portion 1212A to have a smaller gap with respect to the wire member 14 than the fixing portion 1212 of the first embodiment. As a result, the movement of the wire member 14 in the Z-axis direction is suppressed. Consequently, the electronic device 1 can suppress the movement of the top cover 121 in the Z-axis direction.

[0077] [Second Embodiment] Next, with reference to Figures 17 to 24, a battery unit 16a having a wire member 14 and a claw portion 1221 in the second embodiment will be described.

As shown in Figure 23, the contact portion 1222a protrudes in the +Y direction from the end face of the battery housing portion 1222 as it moves in the +Z direction. The other three contact portions 1222a have a similar configuration.

[0085] In the battery housing 1222, the wire member 14a and the contact portion 1222a are fitted together in the same manner as described in Figure 10. When the wire member 14a and the contact portion 1222a are fitted together, the second portion 142a of the wire member 14a comes into contact with the contact portion 1222a.

[0086] Here, the wire member 14a presses its second portion 142a against the contact portion 1222a by elastic force. As the wire member 14a and the contact portion 1222a come into contact, the battery unit 16a is fitted and fixed to the bottom cover 122 at the end of the battery housing portion 1222 in the -Y direction.

[0087] Figure 24 is a perspective view showing the battery housing 1222 of the electronic device 2 according to the second embodiment, viewed from a different angle. As shown in Figure 24, four recesses 1223 are provided at the end of the battery housing 1222 in the +Y direction.
