Description

electronic equipment

[0001] The present invention relates to electronic devices.

[0002] In a conventional electronic device in which a battery and a circuit board are housed in a housing, the battery and the circuit board are arranged side by side in the width direction of the electronic device (for example, Japanese Patent Application Laid-Open No. 2016-5188). In such a configuration, if the area required for the battery and the circuit board is secured, the size of the electronic device in the width direction becomes large.

[0003] On the other hand, Japanese Patent Application Laid-Open No. 2014-36328 describes accommodating a battery and a board in a housing so that the battery and the board face each other in the thickness direction of the mobile phone.

[0004] However, in the latter configuration, a thermal diffusion sheet is provided between the board and the battery, and heat is transferred between the board and the battery. Therefore, there is a risk that heat will be transferred from the board, which generates a lot of heat, to the battery, and that heat will concentrate in the battery. Therefore, even if the electronic device can be made smaller, there is still room for improvement in the heat dissipation performance of the electronic device.

[0005] In view of the above problems, an object of the present invention is to achieve both miniaturization and heat dissipation performance in an electronic device that includes a battery and a substrate.

[0006] The gist of the present disclosure is as follows.

[0008] (2) The electronic device according to (1), wherein the metal frame has a first wall portion that protrudes from the first surface so as to surround the battery.

[0009] (3) The electronic device described in (1) or (2) above, further comprising a fan arranged on the second surface at a position different from the substrate and housed in the housing, the fan facing the battery via the metal frame.

[0010] (4) The electronic device according to (3), wherein the metal frame has a second wall portion protruding from the second surface so as to surround the fan.

[0011] (5) The electronic device described in (3) or (4) above, wherein the housing has an air intake port and an exhaust port, and the air intake port and the exhaust port are each positioned closer to the fan than the battery in a direction perpendicular to the board.

[0012] (6) The electronic device according to any one of (1) to (5), wherein the metal frame is electrically connected to the ground pattern of the substrate.

[0018] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, like components are designated by like reference numerals.

[0019] First Embodiment First, a first embodiment of the present invention will be described with reference to Figures 1 to 6. Figure 1 is a front perspective view of an electronic device 1 according to a first embodiment of the present invention. In this embodiment, the electronic device 1 is a portable electronic device, such as a portable game console, a tablet terminal, a smartphone, a mobile monitor, or an e-book reader. The electronic device 1 has a substantially rectangular parallelepiped shape and is held by a user when in use.

[0020] In this specification, the configuration of the electronic device 1 will be described using an XYZ Cartesian coordinate system set for the electronic device 1. The XYZ Cartesian coordinate system defines the orientation of the electronic device 1 when the electronic device 1 is held by a user and faces the user. Specifically, when the electronic device 1 is held by a user and faces the user, the X-axis direction corresponds to the left-right direction of the electronic device 1, the Y-axis direction corresponds to the up-down direction of the electronic device 1, and the Z-axis direction corresponds to the depth direction (thickness direction) of the electronic device 1. The left and right sides of the electronic device 1 are spaced apart in the X-axis direction, the top and bottom surfaces of the electronic device 1 are spaced apart in the Y-axis direction, and the front and back surfaces of the electronic device 1 are spaced apart in the Z-axis direction.

[0021] 1 , the electronic device 1 includes a housing 2 and a display 3. The housing 2, together with the display 3, forms the outer surface of the electronic device 1. In this embodiment, the length of the electronic device 1 and the housing 2 in the X-axis direction is longer than the length of the electronic device 1 and the housing 2 in the Y-axis direction. Therefore, the X-axis direction corresponds to the longitudinal direction of the electronic device 1 and the housing 2, and the Y-axis direction corresponds to the lateral direction of the electronic device 1 and the housing 2. Furthermore, the left side, right side, top, bottom, front, and back of the housing 2 correspond to the left side, right side, top, bottom, front, and back of the electronic device 1, respectively.

[0022] In this embodiment, the housing 2 includes a first housing 21 and a second housing 22, and is formed by combining the first housing 21 and the second housing 22. When the first housing 21 and the second housing 22 are combined, the first housing 21 and the second housing 22 define an internal space of the housing 2. For example, the first housing 21 and the second housing 22 are each made of resin and are molded by injection molding or the like.

[0023] 1 , in the Z-axis direction, the first housing 21 is disposed on the front side of the electronic device 1, and the second housing 22 is disposed on the rear side of the electronic device 1. The front sides of the electronic device 1 and the housing 2 face the user when the electronic device 1 is used by the user. Note that the front side of the electronic device 1 refers to an area closer to the front side of the electronic device 1 than the rear side of the electronic device 1, and the rear side of the electronic device 1 refers to an area closer to the rear side of the electronic device 1 than the front side of the electronic device 1.

[0024] The display 3 displays visual information (text, images, etc.) to the user. For this reason, the display 3 is provided in the housing 2 so that its display surface is visible to the user. That is, the display 3 is disposed on the front side of the electronic device 1 and is provided in the first housing 21. In this embodiment, the display 3 is disposed in a central region of the electronic device 1 in the X-axis direction and the Y-axis direction. The display 3 is, for example, a liquid crystal display (LCD), an organic EL display, etc. Note that the display 3 may be a touch panel display.

[0025] 2 is a bottom view of the electronic device 1 according to the first embodiment of the present invention. As shown in FIGS. 1 and 2, the housing 2 has an air intake port 23 and an air exhaust port 24. The air intake port 23 is formed on the bottom surface of the housing 2, and the air exhaust port 24 is formed on the top surface of the housing 2. In this embodiment, the air intake port 23 and the air exhaust port 24 are each located on the rear side of the electronic device 1 in the Z-axis direction and are formed in the second housing 22.

[0026] In this embodiment, the air intake 23 includes a first air intake 23a and a second air intake 23b. The first air intake 23a and the second air intake 23b have the same shape and are positioned symmetrically with respect to the left-right center line CL of the electronic device 1. In the X-axis direction, the first air intake 23a is positioned on the right side of the electronic device 1, and the second air intake 23b is positioned on the left side of the electronic device 1. As shown in FIG. 1 , the left-right center line CL of the electronic device 1 refers to a line that bisects the electronic device 1 in the X-axis direction (the left-right direction of the electronic device 1). The right side of the electronic device 1 refers to an area closer to the right side of the electronic device 1 than the left side of the electronic device 1, and the left side of the electronic device 1 refers to an area closer to the left side of the electronic device 1 than the right side of the electronic device 1.

[0027] The exhaust port 24 is disposed on the right side of the electronic device 1 in the X-axis direction and faces the first intake port 23a in the Y-axis direction. That is, the first intake port 23a and the exhaust port 24 are disposed in positions that overlap each other when viewed in the Y-axis direction. The first intake port 23a, the second intake port 23b, and the exhaust port 24 each communicate the internal space of the housing 2 with the outside of the housing 2. In this embodiment, the first intake port 23a, the second intake port 23b, and the exhaust port 24 are each formed as a single slit-shaped hole extending in the X-axis direction.

[0028] The configurations (shape, arrangement, etc.) of the first intake port 23a, the second intake port 23b, and the exhaust port 24 are merely examples, and the first intake port 23a, the second intake port 23b, and the exhaust port 24 may each have other configurations. For example, at least one of the first intake port 23a, the second intake port 23b, and the exhaust port 24 may be formed as multiple holes spaced apart in the X-axis direction. Furthermore, the first intake port 23a and the second intake port 23b may be formed as a single hole.

[0029] Furthermore, exhaust port 24 may be disposed in a central region of electronic device 1 in the X-axis direction. Either first intake port 23a or second intake port 23b may be omitted. In this case, intake port 23 may be disposed in a central region of electronic device 1 in the X-axis direction. Furthermore, at least one of intake port 23 and exhaust port 24 may be formed in first housing 21.

[0030] Alternatively, the intake port 23 may be formed on the top surface of the housing 2, and the exhaust port 24 may be formed on the bottom surface of the housing 2. Alternatively, one of the intake port 23 and the exhaust port 24 may be formed on the right side surface of the housing 2, and the other of the intake port 23 and the exhaust port 24 may be formed on the left side surface of the housing 2.

[0031] Fig. 3 is an exploded perspective view of the electronic device 1 according to the first embodiment of the present invention. Fig. 3 shows the internal components of the electronic device 1, and the housing 2 and display 3 of the electronic device 1 are omitted. As shown in Fig. 3, the electronic device 1 includes a battery 4, a circuit board 5, a fan 6, and a metal frame 7 as internal components accommodated in the housing 2. That is, the battery 4, the circuit board 5, the fan 6, and the metal frame 7 are disposed in the internal space of the housing 2.

[0032] The battery 4 has a substantially rectangular parallelepiped shape and stores power. The electronic device 1 is driven by the power stored in the battery 4. The battery 4 is a secondary battery that can be charged by an external power source, such as a lithium-ion battery or a nickel-metal hydride battery. The battery 4 supplies power to the driving components of the electronic device 1, such as the display 3 and the fan 6, via the board 5.

[0033] Fig. 4 is a rear view of the electronic device 1 according to the first embodiment of the present invention. Fig. 4 shows internal components of the electronic device 1, and illustrates the electronic device 1 with the second housing 22 removed. The substrate 5 is, for example, a thin multilayer substrate, and multiple electronic components (for example, a system on a chip (SoC) 51, etc.) are mounted on the substrate 5.

[0034] 3, the substrate 5 also has a ground pattern 52 electrically connected to the ground potential of the electronic device 1. The ground pattern 52 is made of a conductor such as copper or silver, and is formed by a general processing method (e.g., etching) for providing a wiring pattern on a printed circuit board. In this embodiment, the ground pattern 52 is disposed on one of the multiple layers of the substrate 5.

[0035] The fan 6 is driven by power stored in the battery 4 and generates a flow of air from the air intakes 23 (first air intake 23a and second air intake 23b) to the air exhaust 24. When the fan 6 is driven, air is drawn into the fan 6 from outside the housing 2 through the air intake 23, and the air is blown out from the fan 6. The air blown out from the fan 6 is exhausted to the outside of the housing 2 through the air exhaust 24. Therefore, the air intake 23 functions as an inlet for air drawn into the fan 6, and the air exhaust 24 functions as an outlet for air blown out from the fan 6. The fan 6 cools the battery 4, the circuit board 5, and the metal frame 7 by blowing air.

[0036] 5A is a front perspective view of the metal frame 7, and Fig. 5B is a rear perspective view of the metal frame 7. The metal frame 7 is made of a metal (e.g., magnesium (Mg), aluminum (Al), etc.) and holds the battery 4, the circuit board 5, and the fan 6. The metal frame 7 is formed by die casting, press molding, etc., and is attached to the housing 2 with fasteners such as screws.

[0037] The metal frame 7 has a first surface 71 and a second surface 72 located on opposite sides. As shown in Figures 3 and 4, the first surface 71 is located on the front side of the electronic device 1, and the second surface 72 is located on the rear side of the electronic device 1. The battery 4 is located on the first surface 71 of the metal frame 7. The battery 4 is attached to the first surface 71 by an adhesive member such as double-sided tape or adhesive.

[0038] 3 and 5A , the metal frame 7 has a first wall portion 73 that protrudes from the first surface 71 toward the front side of the electronic device 1. The first wall portion 73 protrudes from the first surface 71 so as to surround the battery 4. This allows the first wall portion 73 to protect the battery 4 and reduce the impact on the battery 4 when the electronic device 1 is dropped, for example. Furthermore, heat from the battery 4 can be transferred to the metal frame 7 not only from the bottom surface of the battery 4 placed on the first surface 71 but also from the side surface of the battery 4 facing the first wall portion 73, thereby improving the heat dissipation performance of the battery 4. In this specification, "a wall portion surrounding a member" means that a wall portion is provided around at least a portion of the periphery of the member.

[0039] In this embodiment, the height of the first wall portion 73 is equal to the thickness of the battery 4, and the battery 4 is housed in the metal frame 7. Therefore, the battery 4 can be firmly protected by the metal frame 7, and heat can be efficiently transferred from the battery 4 to the metal frame 7. Note that "the height of the first wall portion 73 is equal to the thickness of the battery 4" means that the two values ​​are in a range that is substantially equal, and there is substantially no step between the first wall portion 73 and the battery 4.

[0040] 4 , the substrate 5 and the fan 6 are disposed on the second surface 72 of the metal frame 7. The fan 6 is disposed on the second surface 72 at a position different from that of the substrate 5. In this embodiment, the fan 6 is disposed in an area to the left of the substrate 5 in the X-axis direction, and is disposed between the first air intake port 23a and the exhaust port 24 in the Y-axis direction, facing the first air intake port 23a and the exhaust port 24. In other words, the fan 6 is disposed at a position overlapping the first air intake port 23a and the exhaust port 24 when viewed from the Y-axis direction. This allows for smooth airflow from the first air intake port 23a to the fan 6 and from the fan 6 to the exhaust port 24, thereby enhancing the cooling effect of the fan 6.

[0041] In this embodiment, the substrate 5 is attached to the second surface 72 with fastening screws 20a to 20d, and the fan 6 is attached to the second surface 72 with fastening screws 20e to 20g. The fastening screws 20a to 20g are inserted into female threaded portions 75a to 75g provided on the second surface 72, respectively. As shown in FIG. 5B , the metal frame 7 has female threaded portions 75a to 75g, which protrude from the second surface 72 toward the rear surface of the electronic device 1. Note that the female threaded portions 75a to 75g may be nuts or the like attached to the second surface 72.

[0042] In this embodiment, the metal frame 7 is electrically connected to the ground pattern 52 of the board 5 via the fastening screws 20a to 20d. This stabilizes the ground of the board 5. Alternatively, the ground pattern of the board 5 may be provided on the outer surface of the board 5, and the metal frame 7 may be electrically connected to the ground pattern of the board 5 by directly contacting the ground pattern of the board 5 with the metal frame 7.

[0043] The number and arrangement of the fastening screws 20a to 20g and the female screw portions 75a to 75g may be different from those described above. The fastening screws 20a to 20d that secure the substrate 5 may be different from the fastening screws 20e to 20g that secure the fan 6. At least one of the substrate 5 and the fan 6 may be attached to the second surface 72 with an adhesive member such as double-sided tape or adhesive.

[0044] 5B , the metal frame 7 has a second wall portion 74 that protrudes from the second surface 72 toward the rear side of the electronic device 1. The second wall portion 74 protrudes from the second surface 72 so as to surround the fan 6. Therefore, the second wall portion 74 can protect the fan 6 and reduce the impact applied to the fan 6 when the electronic device 1 is dropped, for example.

[0045] 6 is a cross-sectional view of the electronic device 1 taken along line A-A in FIG. 4. As shown in FIG. 6, the metal frame 7 is disposed between the battery 4 and the board 5 in the Z-axis direction, and the board 5 faces the battery 4 in the Z-axis direction via the metal frame 7. That is, the board 5 is disposed in a position that overlaps with the battery 4 when viewed from the Z-axis direction, and is spaced apart from the battery 4 in the Z-axis direction. Therefore, the battery 4 and the board 5 are disposed on different XY planes (planes perpendicular to the Z-axis) within the housing 2. This allows the electronic device 1 to be miniaturized while ensuring sufficient area for the battery 4 and the board 5.

[0046] Furthermore, heat from the battery 4 is transferred from one side of the metal frame 7 to the metal frame 7, and heat from the board 5 is transferred from the other side of the metal frame 7 to the metal frame 7. Therefore, the battery 4 and the board 5 can be thermally separated by the metal frame 7, and the heat dissipation performance of the electronic device 1 can be improved. Therefore, according to this embodiment, in the electronic device 1 including the battery 4 and the board 5, it is possible to achieve both miniaturization and heat dissipation performance of the electronic device 1. Furthermore, in this embodiment, the metal frame 7 can be cooled by air blown by the fan 6, and therefore the heat dissipation performance of the electronic device 1 can be further improved.

[0047] 6 , the metal frame 7 is disposed between the battery 4 and the fan 6 in the Z-axis direction, and the fan 6 faces the battery 4 via the metal frame 7 in the Z-axis direction. That is, the fan 6 is disposed in a position overlapping the battery 4 when viewed in the Z-axis direction and is separated from the battery 4 in the Z-axis direction. Therefore, the battery 4 and the fan 6 are disposed on different XY planes within the housing 2. On the other hand, the fan 6 is disposed adjacent to the board 5 in the X-axis direction, and the board 5 and the fan 6 are disposed on the same XY plane within the housing 2. This allows the area of ​​the battery 4 to be larger than the area of ​​the board 5, thereby ensuring the capacity of the battery 4. Furthermore, since the fan 6 is disposed adjacent to the board 5, which generates more heat than the battery 4, more air can be guided to the board 5 than to the battery 4, thereby improving the heat dissipation effect of the electronic device 1.

[0048] Furthermore, as described above, the intake port 23 and the exhaust port 24 are formed in the second housing 22 and disposed on the rear side of the electronic device 1. For this reason, in this embodiment, the intake port 23 and the exhaust port 24 are disposed at positions closer to the fan 6 and the board 5 than the battery 4 in the Z-axis direction, i.e., the direction perpendicular to the board 5. This allows the air to flow smoothly from the intake port 23 to the fan 6 and from the fan 6 to the exhaust port 24, thereby enhancing the cooling effect of the fan 6.

[0049] Second Embodiment An electronic device according to a second embodiment is basically the same as the electronic device according to the first embodiment, except for the points described below. Therefore, the second embodiment of the present invention will be described below, focusing on the differences from the first embodiment.

[0050] 7 is an exploded perspective view of an electronic device 1' according to a second embodiment of the present invention, showing some components of the electronic device 1', with the housing 2, board 5, and fan 6 of the electronic device 1' omitted.

[0051] As in the first embodiment, in the electronic device 1′, the display 3 is provided in the housing 2 such that the battery 4 is located between the display 3 and the metal frame 7. That is, the display 3 and the battery 4 are arranged closer to the front than the metal frame 7. However, unlike the first embodiment, the electronic device 1′ further includes a battery cover 8, a first cushioning material 9, and a second cushioning material 10. The battery cover 8, the first cushioning material 9, and the second cushioning material 10 are arranged between the display 3 and the battery 4 and are accommodated in the housing 2.

[0052] The battery cover 8 has a thin plate shape and covers the battery 4. The battery cover 8 is made of, for example, stainless steel (SUS). The battery cover 8 prevents direct contact between the battery 4 and the display 3, thereby reducing the impact applied to the battery 4 and the display 3 when the electronic device 1' is dropped. Therefore, the battery cover 8 increases the strength of the battery 4 and the display 3. Furthermore, even if the battery cover 8 makes it difficult for the battery 4 to dissipate heat, the electronic device 1' can still ensure the heat dissipation performance of the battery 4 by dissipating heat from the battery 4 to the metal frame 7.

[0053] The first cushioning material 9 is provided between the battery cover 8 and the battery 4 and has a lower modulus of elasticity than the battery cover 8. The first cushioning material 9 is made of a cushioning material (e.g., urethane foam). The first cushioning material 9 has a square shape and covers the periphery of the battery 4. The first cushioning material 9 fills the gap between the battery cover 8 and the battery 4, preventing dust and other particles from entering the gap. The first cushioning material 9 also absorbs impact between the battery cover 8 and the battery 4, further reducing the impact applied to the battery 4 when the electronic device 1' is dropped, for example. Furthermore, a rectangular cavity is formed in the center of the first cushioning material 9.

[0054] The second cushioning material 10 is provided between the battery cover 8 and the display 3 and has a lower modulus of elasticity than the battery cover 8. The second cushioning material 10 is made of a cushioning material (e.g., urethane foam). The second cushioning material 10 is composed of a pair of members extending in the X-axis direction and covers the upper and lower edges of the display 3. The second cushioning material 10 fills the gap between the battery cover 8 and the display 3, preventing dust and other particles from entering the gap. The second cushioning material 10 also absorbs impacts between the battery cover 8 and the display 3, reducing the impact on the display 3 when the electronic device 1' is dropped, for example.

[0055] The first cushioning material 9 may cover a portion of the periphery of the battery 4. For example, the first cushioning material 9 may be made up of a pair of members extending in the X-axis direction, similar to the second cushioning material 10. The second cushioning material 10 may cover the entire periphery of the display 3. For example, the second cushioning material 10 may have a square shape, similar to the first cushioning material 9. At least one of the first cushioning material 9 and the second cushioning material 10 may be omitted.

[0056] Other Embodiments While preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications and variations can be made within the scope of the claims. For example, the housing 2 may be formed from three or more members (e.g., a front member, a rear member, and a side member). Furthermore, in addition to the display 3, a power button, operation buttons, speaker holes, USB ports, etc. may be provided on the exterior of the housing 2.

[0057] Alternatively, the first surface 71 of the metal frame 7 may be disposed on the rear side of the electronic device 1, and the second surface 72 of the metal frame 7 may be disposed on the front side of the electronic device 1. In this case, the circuit board 5 and the fan 6 are disposed on the front side of the electronic device 1, and the battery 4 is disposed on the rear side of the electronic device 1. That is, the display 3 is provided in the housing 2 such that the circuit board 5 and the fan 6 are located between the display 3 and the metal frame 7. This arrangement makes it easy to access the battery 4 from the rear side of the electronic device 1, thereby facilitating replacement or repair of the battery 4. Note that in this arrangement in which the fan 6 is disposed on the front side of the electronic device 1, the intake port 23 and the exhaust port 24 may be formed in the first housing 21 and disposed on the front side of the electronic device 1.

[0058] The display 3 may also be omitted from the electronic device 1. The fan 6 may also be omitted from the electronic device 1, 1′. In this case, too, the heat from the battery 4 and the board 5 can be collected in the metal frame 7, thereby improving the heat dissipation performance of the electronic device 1, 1′.
