Problems to be Solved by the Invention

[0004] By the way, the antenna element and the antenna module may be connected by a coaxial cable.

[0010] The embodiments of the present invention will be described in detail below with reference to the drawings. However, the present invention is not limited to these embodiments.

[0011] Figure 1 is a schematic plan view of an electronic device 10 according to one embodiment, viewed from above. As shown in Figure 1, the electronic device 10 in this embodiment is a clamshell-type notebook PC. The electronic device 10 has a configuration in which a lid 11 and a housing 12 are connected by a hinge 14 so that they can rotate relative to each other. In this embodiment, a notebook PC electronic device 10 is used as an example, but the electronic device may be something other than a notebook PC, such as a tablet PC, smartphone, or portable game console.

[0012] The lid 11 is a thin, flat, box-shaped enclosure. The lid 11 houses a display 16. The display 16 is, for example, an organic EL display or a liquid crystal display.

[0013] The housing 12 is a thin, flat box. The keyboard device 18 and touchpad 19 face the top surface 12a of the housing 12. Hereinafter, the housing 12 and each component mounted thereon will be described using the operator's posture when operating the keyboard device 18 as the reference point, with the width direction (left and right) of the housing 12 being referred to as the X1 and X2 directions, the depth direction (front and back) of the housing 12 being referred to as the Y1 and Y2 directions, and the thickness direction (up and down) of the housing 12 being referred to as the Z1 and Z2 directions. The X1 and X2 directions may also be collectively referred to as the X direction, and similarly, the Y1 and Y2 directions and the Z1 and Z2 directions may be referred to as the Y direction and Z direction. These directions are defined for the convenience of explanation and may naturally change depending on the usage state or installation posture of the electronic device 10. In this application, left and right pairs of components may be denoted with "L" and right with "R".

[0014] The housing 12 can be composed of a plate-shaped member 20 that forms the top surface 12a, a cover member 21 that forms the bottom surface 12b, and vertical wall members 22 that form the four sides 12c. The rear portion of the side 12c is called the rear side 12ca. The plate-shaped member 20 has a large rectangular opening 20a in which the keyboard device 18 is placed. The side 12c of the housing 12 is mostly occupied by the vertical wall members 22, but the wall portion 39c (see Figure 5), which will be described later, also occupies a portion. The plate-shaped member 20 and the cover member 21 are formed by press molding of metal material, resulting in a high-quality finish. The plate-shaped member 20 and the cover member 21 are almost entirely metal. The vertical wall member 22 is made of resin material, but it may also be made of metal material integrated with the plate-shaped member 20 or the cover member 21. The plate-shaped member 20 and the cover member 21 are not radio wave transparent, but the wall portion 39c is radio wave transparent.

[0015] The hinge 14 is installed in a concave hinge placement groove 12d formed on the rear side surface 12ca of the housing 12, and connects the housing 12 and the lid 11. The hinge 14 has a structure in which, for example, hinge shafts serving as rotation axes are respectively supported at both longitudinal ends of a hinge housing 14a. The hinge 14 of the present embodiment is configured in a so-called one-bar shape in which the hinge housing 14a extends along the longitudinal direction of the hinge placement groove 12d. The hinge 14 descends obliquely rearward while the hinge housing 14a rotates integrally with the lid 11. The hinge 14 has a structure that gains the rotation angle of the lid 11 in this way, a so-called drop-down structure. The structure of the hinge 14 may be other than the above.

[0016] Figure 2 is a view of the inside of the housing 12 as seen from the lower surface side with the cover member 21 removed. As shown in Figure 2, the inside of the housing 12 is almost occupied by the motherboard 25 in the rear half, and almost occupied by the battery 26 in the front half. A CPU 27, an antenna module 28, a memory module 29, etc. are mounted on the motherboard 25. Two fans 30L and 30R are provided at positions far enough apart left and right near the rear of the motherboard 25. The fans 30L and 30R are provided at left and right positions sandwiching the main exhaust port 45 and the sub-exhaust ports 46L and 46R described later. The fans 30L and 30R are respectively arranged in cutouts of the motherboard 25, and air outlets 30a are formed on the facing side edges, and they blow air toward each other and can blow air on the upper and lower surfaces of the motherboard 25. The fans 30L and 30R are configured to intake air from an intake port (not shown) formed in the cover member 21, etc.

[0017] The CPU 27 is mounted on the motherboard 25 at a substantially intermediate position between the two fans 30L and 30R. A heat dissipation member 3 that extends almost without a gap between the fans 30L and 30R is pressed against the CPU 27 by a rear leaf spring 32 and a front leaf spring 33. The heat dissipation member 31 absorbs and diffuses the heat of the CPU 27.

[0018] The front ends of the air outlets 30a of the fans 30L and 30R are blocked by a sponge 34. The sponge 34 has a flat U-shaped configuration that bulges slightly forward so as to surround the heat dissipation member 31 and the leaf spring 33. A pair of short sponges 35 extend from near the rear ends of the air outlets 30a of the fans 30L and 30R in directions approaching each other. The sponges 35 block approximately half of the space between the fans 30L and 30R and the leaf spring 32. The sponges 34 and 35 are fixed to the motherboard 25. The fans 30L and 30R are provided with a sponge 36 extending from the air outlets 30a to the rear side. The sponges 34, 35, and 36 block the space between them and the cover member 21, and the air blown by the fans 30L and 30R is exhausted from the main exhaust port 45 at the center of the rear side and the sub-exhaust ports 46L and 46R on both sides thereof, so that the CPU 27 can be efficiently cooled.

[0019] The antenna module 28 and the antenna elements 39L and 39R described in the following paragraph are compatible with WWAN, WLAN, etc. The antenna module 28 is adjacent to the front side of the fan 30R. Two terminals 28aa and 28ab are provided at the right end of the antenna module 28. The memory module 29 is provided slightly in front of the fan 30L. A board connector 37R is provided between the fan 30R and the leaf spring 32, and a board connector 37L is provided between the fan 30L and the leaf spring 32. Flat cables 38L and 38R are connected to the board connectors 37L and 37R, respectively, and extend to the lid 11.

[0020] Two antenna elements 39L and 39R are provided at the rear end of the housing 12. The antenna element 39R is adjacent to the rear side of the fan 30R, and the antenna element 39L is adjacent to the rear side of the fan 30L. Plate pieces 40L are arranged side by side immediately to the right of the antenna element 39L, and plate pieces 40R are arranged side by side immediately to the left of the antenna element 39R. The plate pieces 40L and 40R are for appropriately adjusting the path lengths of the flat cables 38L and 38R.

[0021] Antenna element 39L and terminal 28aa of antenna module 28 are connected by coaxial cable 41L. Antenna element 39R and terminal 28ab of antenna module 28 are connected by coaxial cable 41R. Coaxial cable 41R extends slightly to the right from terminal 28ab, then turns rearward, passing to the right of fan 30L to reach antenna element 39R. Coaxial cable 41L extends slightly to the right from terminal 28aa, then turns rearward almost parallel to coaxial cable 41R, and further extends to the left along the rear side surface 12ca, which is the rear edge of housing 12, to reach antenna element 39L.

[0022] Therefore, coaxial cable 41L is longer than coaxial cable 41R. Coaxial cables 41L and 41R are identical except for their length, and have a conductor, insulator, shield, and sheath arranged concentrically radially from the center, with ends 41La and 41Ra connected to terminals 28aa and 28ab. The shield is grounded. Coaxial cables 41L and 41R have a reasonable amount of slack on the left side of fan 30L and are each secured by two clips 42. Coaxial cables 41L and 41R pass through a relatively narrow space between fan 30L and element 43. The portion of coaxial cable 41L that follows the rear side 12ca of housing 12 is almost completely covered by bracket 44. The antenna element 39L, coaxial cable 41L, and bracket 44 constitute the antenna unit 50 (see Figure 4).

[0023] Figure 3 is a schematic diagram of the rear side 12ca of the housing 12. As described above, most of the side 12c, including the rear side 12ca, is made up of vertical wall members 22. The vertical wall member 22 of the rear side 12ca has a main exhaust port 45 and two sub-exhaust ports 47L and 47R. The main exhaust port 45 is made up of several (in this case, four) relatively large exhaust windows 45a arranged in the center of the cover member 21. The sub-exhaust ports 47L and 47R are formed to the left and right of the main exhaust port 45 and consist of several (in this case, three) relatively small exhaust windows 47a. Mesh 48 is provided in the exhaust windows 45a and 47a. The mesh 48 is coarse enough not to obstruct exhaust, and the inside can be seen to some extent from the outside of the housing 12 through the mesh 48.

[0024] Small pieces 64L and 64R are provided at both the left and right ends of the cover member 21 to cover the hinge 14. Antenna elements 39L and 39R are positioned in recesses 49L and 49R between the small pieces 64L and 64R and the sub-exhaust port 47. The airflow through the sub-exhaust ports 47L and 47R is relatively low because of the proximity of the sponge 35 (see Figure 2) and board connectors 37L and 37R, and most of the air blown from the fans 30L and 30R is exhausted through the main exhaust port 45. The main exhaust port 45 is located in an area generally opposite the leaf spring 32. The plate pieces 40L and 40R (see Figure 2) are located between the board connectors 37L and 37R and the sub-exhaust ports 47L and 47R.

[0025] Let me describe the antenna unit 50. As described above, the antenna unit 50 consists of an antenna element 39L, a coaxial cable 41L, and a bracket 44. It is pre-assembled into a unit, and can be treated as a single component during the assembly process of the electronic equipment 10, resulting in good workability.

[0026] Figure 4 is a perspective view of the antenna unit 50. The arrows indicating orientation in Figures 4, 5, and 7 are based on the orientation of the bracket 44. The bracket 44 consists of a linear central bracket 52 and lateral brackets 53L and 53R. The central bracket 52 and lateral brackets 53L and 53R are provided in the portions that traverse the main exhaust port 45 and sub-exhaust ports 47L and 47R in the longitudinal X direction, respectively. The central bracket 52 and the lateral brackets 53L and 53R are connected by joint portions 54L and 54R. The entire bracket 44, including the joint portions 54L and 54R, is constructed by bending a single metal plate and has a shielding effect. The bracket 44 may be surface-treated with nickel plating or the like. The bracket 44 does not have an insulating coating, and at least the surface is conductive at the stage of the conductivity treatment described later.

[0027] Figure 5 shows the side bracket 53L and antenna element 39L of the antenna unit 50, where (a) is a top view, (b) is a rear view, and (c) is a bottom view. Regarding the bracket 44, Figure 5(c) and Figure 6(c) described later are in the same orientation as in Figure 2 when assembled to the housing. In Figure 5, the antenna element 39L is shown rotated 90 degrees compared to Figure 2.

[0028] The antenna element 39L has an element body 39a, fixing pieces 39b provided on its left and right sides, and a wall portion 39c that stands upright at the rear. The element body 39a is connected to the coaxial cable 41L. The fixing pieces 39b are provided with screw holes 39ba and positioning holes 39bb. The wall portion 39c forms part of the vertical wall member 22. The wall portion 39c is made of resin material and is radio wave transparent. The antenna element 39R is symmetrical to the antenna element 39L and has almost the same shape.

[0029] The lateral bracket 53L has a fixing piece 53a formed at its left end, close to the antenna element 39L. The connection portion of the joint 54L with the lateral bracket 53L forms a fixing piece 53b. The fixing pieces 53a and 53b are arranged horizontally. A plate piece 40L (see Figure 2) is positioned between the fixing pieces 53a and 53b.

[0030] The fixing pieces 53a and 53b have screw holes 53aa and 53ba formed approximately in the center. Screw holes 53aa and 39ba overlap when the housing is assembled and are fastened together with a single screw to a predetermined stud on the bezel member 61 (see Figure 10), which will be described later. Screw hole 53ba is fixed to a predetermined stud on the bezel member 61. A positioning notch 53ab is formed in the fixing piece 53a. The positioning notch 53ab and the positioning hole 39bb overlap when the housing is assembled and are positioned by a predetermined pin on the bezel member 61. A fixing hole 53bb is formed in the fixing piece 53b slightly closer to X1 and is positioned by a predetermined pin on the bezel member 61. Hooks 53ac and 53bc are wound around the fixing pieces 53a and 53b in a sleeve-like manner to fix the coaxial cable 41L. The fixing pieces 53a and 53b are provided with thin, short overhangs 53ad and 53bd that follow the coaxial cable 41L.

[0031] Figure 6 is a cross-sectional view taken along lines VI to VI in Figure 5. The lateral bracket 53L has a rear wall 53d, a lower wall 53e, and a canopy portion 53f, covering the rear and lower sides of the coaxial cable 41L, with the front and upper sides open. The rear wall 53d and the lower wall 53e are in close contact with the coaxial cable 41L. The canopy portion 53f protrudes horizontally from the end of the rear wall 53d. The canopy portion 53f is located between the canopy portions 53ad and 53bd (see Figure 5(a)). The lateral bracket 53L is stabilized by the canopy portions 53f, 53ad, and 53bd contacting the top surface 61aa (see Figure 10), which will be described later.

[0032] A portion of the sheath of the coaxial cable 41L is cut away to expose the shield, and the exposed conductive section 56 is connected to the side bracket 53L of the bracket 44 by solder 57. As shown in Figure 5, the conductive section 56 is located approximately in the center of the side bracket 53L where the overhang 53f is located. The conductive sections 58 of the coaxial cable 41L at locations on the left and right that are separated from the overhang are similarly connected by solder 57. The conductive connections may also be made using a crimping tool.

[0033] The joint portion 54L has a shape with small steps in the front-to-back and up-to-down directions. Therefore, the lateral bracket 53L and the central bracket 52 are slightly offset from each other in the front-to-back and up-to-down directions. Specifically, the lateral bracket 53L is positioned slightly rearward and slightly downward relative to the central bracket 52, so as to satisfy the layout requirements with other components within the housing 12. The lateral bracket 53L and the joint portion 54L have been described so far, but the lateral bracket 53R and the joint portion 54R have a symmetrical and almost identical configuration to the lateral bracket 53L and the joint portion 54L.

[0034] Figure 7 shows the central bracket 52 in the antenna unit 50, where (a) is a top view, (b) is a rear view, and (c) is a bottom view. Figure 8 is a cross-sectional view taken along lines VIII to VIII in Figure 7.

[0035] The central bracket 52 has a front wall 52a, a rear inclined wall 52b, a bottom wall 52c, and an upper wall 52d, and is shaped to almost completely cover the coaxial cable 41L both front-to-back and above-and-below. The inclined wall 52b and the bottom wall 52c correspond to the rear wall 53d and the bottom wall 53e of the lateral bracket 53L. The upper wall 52d protrudes horizontally towards the rear from the upper end of the front wall 52a. The upper wall 52d protrudes even further behind the end of the inclined wall 52b, and this portion corresponds to the rear end of the canopy portion 53f of the lateral bracket 53L. There is almost no gap between the upper wall 52d and the end of the inclined wall 52b.

[0036] Figure 9 is a cross-sectional view taken along the line IX to IX in Figure 7. As shown in Figure 9 and Figure 7(a), the central bracket 52 has two notched openings 59 extending from the front wall 52a to the upper wall 52d. The notched openings 59 have slightly deeper notches 59a at both ends and a slightly deeper notch 59b in the center on the upper wall 52d. The notches 59a are narrow, and the notches 59b are slightly wider. The two notched openings 59 are formed to be relatively long in the X direction, and in this embodiment, the combined length of the two occupies approximately 2 / 3 of the total length of the central bracket 52.

[0037] The coaxial cable 41L has a portion of its sheath cut away to expose the shield, and two exposed conductive sections 60 are connected to the central bracket 52 of the bracket 44 by solder 57. The two conductive sections 60 are located in the notches 59b of the notched opening 59. The length of the conductive sections 56, 58, and 60 in the X direction is, for example, about 3 mm. In addition, the solder 57 of the conductive sections 56, 58, and 60 is formed so that it does not protrude from the lateral bracket 53L or the central bracket 52 in cross-section. The conductive sections 56, 58, and 60 are arranged in a balanced manner with an appropriate distance between them.

[0038] Figure 10 is a schematic cross-sectional view of the rear portion of the enclosure 12. The cover 11 is omitted in Figure 10. In Figure 10, reference numeral 18a denotes the keyboard bracket of the keyboard device 18, and reference numeral 18b denotes the keytop. The three white arrows in Figure 10 indicate the airflow from fans 30L and 30R to the exhaust window 45a. One of these flows through the narrow gap between the motherboard 25 and the keyboard bracket 18a, and the airflow is relatively small. The other two flow through the gap between the motherboard 25 and the bottom surface 12b, and the airflow is relatively large.

[0039] An inclined surface 20b is formed around the opening 20a of the plate-shaped member 20, and the keytop 18b is positioned at a slightly lower position. A bezel member 61 is fixed to the inner surface of the plate-shaped member 20 around the opening 20a. The bezel member 61 is made of metal and is used to fix the keyboard bracket 18a and bracket 44, and is electrically connected to the plate-shaped member 20. As described above, the bracket 44 is fixed to the studs of the bezel member 61, and is electrically connected to the housing 12 via the bezel member 61. In other words, the bezel member 61 and its studs can be considered as the electrical connection section of the bracket 44.

[0040] The bezel member 61 is provided across the front and rear of the inclined surface 20b, and a rectangular notch 61a is formed on the lower surface of the inclined surface 20b from approximately the middle to the rear. The keyboard bracket 18a is fixed in front of the rectangular notch 61a, and the bracket 44 is fixed so that its upper wall 52d is in contact with the top surface 61aa of the rectangular notch 61a. The rear ends of the bezel member 61 and the bracket 44 are almost coincidental. The gap between the respective rear ends of the bezel member 61 and the bracket 44 and the upper edge 45aa, which is one edge of the exhaust window 45a, is small.

[0041] The component 62 attached to the keyboard bracket 18a is a black tape that conceals the metal part, and its rear end 62a is bent to form an L-shape so that it fits into the rectangular cutout 61a. The component 62 is made up of two pieces. The gaps between the front surface 61ab of the rectangular cutout 61a and the rear end 62a, and between the rear end 62a and the bracket 44 are small. The lower wall 52c of the bracket 44 is slightly higher than the keyboard bracket 18a. The upper wall 52d of the bracket 44 is positioned slightly upward so as not to narrow the exhaust window 45a.

[0042] The bracket 44 is positioned along the upper edge 45aa and, due to the layout requirement of making the housing 12 thin, is located within the housing 12, including the range of the short Y-direction opening width W of the exhaust port. The inclined wall 52b of the bracket 44 forms an upward-sloping surface toward the rear, substantially toward the upper edge 45aa, so as not to obstruct the airflow indicated by the arrow, the cooling efficiency is improved.

[0043] The inclined wall 52b is positioned to face the exhaust window 45a at an angle, covering most of the coaxial cable 41L so that it is not visible through the exhaust window 45a, which is aesthetically pleasing. The notched opening 59 is formed from the front wall 52a to the upper wall 52d, so it is not visible from outside the exhaust window 45a. The same applies to the conductive processing section 60 and the solder 57. The coaxial cable 41L is supported by the bracket 44, so it does not sag or shift unintentionally. Since the coaxial cable 41L is covered by the bracket 44, it is not exposed to airflow and does not vibrate.

[0044] In the electronic device 10 according to this embodiment, the coaxial cable 41L is provided relatively long along the longitudinal direction of the main exhaust port 45. This portion is covered with a bracket 44 that has conductive and electromagnetic shielding properties on its surface. Furthermore, the shield portion of the coaxial cable 41L is electrically connected to the bracket 44, and is electrically connected to the metal part of the housing 12 via the bracket 44. Thus, the electromagnetic shielding performance of the coaxial cable 41L can be improved.

[0045] The two fans 30L and 30R are located within the chassis 12, flanking the main exhaust port 45, and the CPU 27 is located between the two fans 30L and 30R. The CPU 27 is prone to generating electromagnetic noise, and the main exhaust port 45 is in a position that is susceptible to this noise. However, the coaxial cable 41L, which has been treated as described above, has improved electromagnetic shielding performance and is therefore applicable.

[0046] The bracket 44 is made of a metal plate, which is conductive, has sufficient strength even if it is relatively thin, and is easy to process, making it preferable. However, depending on the design conditions, the bracket 44 may be made of resin material. In this case, it is preferable to make the surface conductive by metal plating such as LDS (Laser Direct Structuring), and to perform a conductive treatment between the plated part and the shield part.

[0047] The present invention is not limited to the embodiments described above, and can be freely modified without departing from the spirit of the invention. [Explanation of Symbols]
