Description

[Technical Field]

[0001] The present invention relates to an electronic device including an antenna element and a coaxial cable connected to the antenna element, and to an antenna unit. [Background technology]

[0002] Electronic devices such as notebook PCs (notebook personal computers) are equipped with antennas for various wireless communications such as WWAN (Wireless Wide Area Network) and WLAN (Wireless Local Area Network). Providing the antenna element on the side of the housing is preferable because it allows for no barrier to transmitting and receiving signals from the outside. In the electronic device described in Patent Document 1, the antenna element is provided on the side of the housing, and a shielding film is provided between the antenna element and a motherboard on which electronic components are mounted, providing electromagnetic shielding.

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings. However, the present invention is not limited to the embodiments.

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

[0012] The cover 11 is a thin, flat, box-shaped housing. The cover 11 is equipped with 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. A keyboard device 18 and a touchpad 19 face the top surface 12a of the housing 12. Hereinafter, the housing 12 and each of the components mounted thereon will be described based on the operator's posture when operating the keyboard device 18. The width direction (left and right) of the housing 12 will be referred to as the X1 and X2 directions, the depth direction (front and back) of the housing 12 as the Y1 and Y2 directions, and the thickness direction (up and down) of the housing 12 as the Z1 and Z2 directions. The X1 and X2 directions will sometimes be collectively referred to as the X direction, and the Y1, Y2 directions and the Z1, Z2 directions will sometimes be similarly referred to as the Y direction and the Z direction. These directions are defined for convenience of explanation and may naturally change depending on the usage state or installation posture of the electronic device 10. In this application, the left component of a pair of left and right components will sometimes be marked with "L" and "R," respectively.

[0014] The housing 12 may be composed of a plate-shaped member 20 forming the top surface 12a, a cover member 21 forming the bottom surface 12b, and upright wall members 22 forming the four peripheral side surfaces 12c. The rear portion of the side surface 12c is designated as a rear side surface 12ca. The plate-shaped member 20 has a large rectangular opening 20a in which the keyboard device 18 is disposed. The side surface 12c of the housing 12 is mostly occupied by the upright wall member 22, but also partially occupied by a wall portion 39c (see FIG. 5 ), which will be described later. The plate-shaped member 20 and the cover member 21 are formed by press molding of a metal material, giving them a high-quality texture. Almost the entire plate-shaped member 20 and the cover member 21 are metal. The upright wall member 22 is made of a resin material, but may also be made of a metal material integral 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 permeable, but the wall portion 39c is radio wave permeable.

[0015] The hinge 14 is installed in a concave hinge placement groove 12d formed in the rear side surface 12ca of the housing 12, and connects the housing 12 and the cover 11. The hinge 14 has a structure in which, for example, hinge shafts serving as rotation axes are supported at both longitudinal ends of the hinge housing 14a. The hinge 14 of this 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 rotates integrally with the cover 11 while descending diagonally rearward. The hinge 14 has a structure that increases the rotation angle of the cover 11 in this way, a so-called drop-down structure. The hinge 14 may have a structure other than that described above.

[0016] FIG. 2 is a bottom view of the interior of the housing 12 with the cover member 21 removed. As shown in FIG. 2, the rear half of the interior of the housing 12 is occupied by a motherboard 25, and the front half is occupied by a battery 26. Components such as a CPU 27, an antenna module 28, and a memory module 29 are mounted on the motherboard 25. Two fans 30L and 30R are provided near the rear of the motherboard 25, spaced far apart on the left and right. The fans 30L and 30R are located on either side of a main exhaust port 45 and sub-exhaust ports 46L and 46R (described later). The fans 30L and 30R are each located in a notch in the motherboard 25, with air outlets 30a formed on the edges facing each other. The fans 30L and 30R blow air toward each other, allowing them to blow air to both the top and bottom of the motherboard 25. The fans 30L and 30R draw air through air intakes (not shown) formed in the cover member 21.

[0017] The CPU 27 is mounted on the motherboard 25 at a position approximately midway between the two fans 30L and 30R. A heat diffusion member 31 extends between the fans 30L and 30R with almost no gap between them, and is pressed against the CPU 27 by a rear leaf spring 32 and a front leaf spring 33. The heat diffusion member 31 absorbs and diffuses heat from the CPU 27.

[0018] A sponge 34 seals the gap between the front ends of the air outlets 30a of the fans 30L and 30R. The sponge 34 has a flattened U-shape that protrudes slightly forward so as to surround the heat diffusion member 31 and the leaf spring 33. A pair of short sponges 35 extend toward each other from the rear ends of the air outlets 30a of the fans 30L and 30R. The sponges 35 seal approximately half of the gap between the fans 30L and 30R and the leaf spring 32. The sponges 34 and 35 are fixed to the motherboard 25. A sponge 36 is provided on the fans 30L and 30R, extending from the air outlets 30a to the rear. The sponges 34, 35, and 36 seal the gap between the cover member 21 and the fans, allowing the air blown by the fans 30L and 30R to be exhausted through the main exhaust port 45 located in the center of the rear side and the sub-exhaust ports 46L and 46R on either side of it, thereby efficiently cooling the CPU 27.

[0019] The antenna module 28 and antenna elements 39L, 39R, which will be described in the next paragraph, are compatible with WWAN, WLAN, and the like. The antenna module 28 is adjacent to and immediately in front of the fan 30R. Two terminals 28aa, 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, 38R are connected to the board connectors 37L, 37R, and extend to the cover 11, respectively.

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

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

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

[0023] FIG. 3 is a schematic diagram of the rear side surface 12ca of the housing 12. As described above, most of the side surface 12c, including the rear side surface 12ca, is formed with the standing wall member 22. The standing wall member 22 of the rear side surface 12ca has a main exhaust port 45 and two sub-exhaust ports 47L and 47R formed therein. The main exhaust port 45 is formed in the center of the cover member 21 with a plurality of (four in this case) relatively large exhaust windows 45a lined up. The sub-exhaust ports 47L and 47R are formed on the left and right sides of the main exhaust port 45 and are formed with a plurality of (three in this case) relatively small exhaust windows 47a. A mesh 48 is provided in the exhaust windows 45a and 47a. The mesh 48 is coarse enough not to obstruct exhaust, and the interior of the housing 12 can be somewhat seen through the mesh 48 from the outside.

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

[0025] The following describes the antenna unit 50. As described above, the antenna unit 50 is composed of the antenna element 39L, the coaxial cable 41L, and the bracket 44, and is pre-assembled into a unit form. Since it can be handled as a single component in the assembly process of the electronic device 10, it is easy to work with.

[0026] FIG. 4 is a perspective view of the antenna unit 50. The arrows indicating the direction in FIGS. 4, 5, and 7 are based on the orientation of the bracket 44. The bracket 44 is composed of a linear center bracket 52 and side brackets 53L and 53R. The center bracket 52 and the side brackets 53L and 53R are provided in portions that cross the main exhaust port 45 and the sub-exhaust ports 47L and 47R, respectively, in the longitudinal X direction. The center bracket 52 and the side brackets 53L and 53R are connected by joint portions 54L and 54R. The bracket 44, including the joint portions 54L and 54R, is formed by bending a single metal plate, providing a shielding effect. The bracket 44 may be subjected to a surface treatment such as nickel plating. The bracket 44 does not have an insulating coating, and its surface is conductive at least during the conductivity treatment described below.

[0027] 5A and 5B are diagrams showing the side bracket 53L and antenna element 39L of the antenna unit 50, with (a) being a plan view, (b) being a rear view, and (c) being a bottom view. The bracket 44 in FIG. 5C and FIG. 6C (described later) is oriented in the same direction as in FIG. 2 when assembled to the housing. In FIG. 5, the antenna element 39L is shown shifted by 90 degrees from FIG. 2.

[0028] The antenna element 39L has an element body 39a, fixing pieces 39b provided on the left and right sides thereof, and a wall portion 39c erected at the rear. The element body 39a is connected to the coaxial cable 41L. The fixing piece 39b is provided with a screw hole 39ba and a positioning hole 39bb. The wall portion 39c forms a part of the erect wall member 22. The wall portion 39c is made of a 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 side bracket 53L has a fixed piece 53a formed at its left end near the antenna element 39L. The connecting portion of the joint 54L with the side bracket 53L forms a fixed piece 53b. The fixed pieces 53a and 53b are arranged horizontally. The plate piece 40L (see Figure 2) is arranged between the fixed piece 53a and the fixed piece 53b.

[0030] Screw holes 53aa and 53ba are formed in the approximate centers of the fixing pieces 53a and 53b. When the housing is assembled, the screw holes 53aa and 39ba are aligned and fastened together with a single screw to a predetermined stud on a bezel member 61 (see FIG. 10 ), which will be described later. The 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 are aligned and positioned by a predetermined pin on the bezel member 61 when the housing is assembled. A positioning hole 53bb is formed in the fixing piece 53b at a position slightly toward 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 secure the coaxial cable 41L. The fixing pieces 53a and 53b are provided with thin, short visors 53ad and 53bd that fit along the coaxial cable 41L.

[0031] 6 is a cross-sectional view taken along line VI-VI in FIG. 5. The side bracket 53L has a rear wall 53d, a lower wall 53e, and a visor portion 53f, and covers the rear and lower sides of the coaxial cable 41L while being open on the front and upper sides. The rear wall 53d and the lower wall 53e are in substantial contact with the coaxial cable 41L. The visor portion 53f protrudes horizontally from the end of the rear wall 53d. The visor portion 53f is provided between the visor portions 53ad and 53bd (see FIG. 5(a)). The visor portions 53f, 53ad, and 53bd abut against a top surface 61aa (see FIG. 10), which will be described later, thereby stabilizing the side bracket 53L.

[0032] A portion of the sheath of the coaxial cable 41L is cut away to expose the shield, and the exposed electrical continuity processing portion 56 is electrically connected to the side bracket 53L of the bracket 44 by solder 57. As shown in Fig. 5, the electrical continuity processing portion 56 is provided in the approximate center of the side bracket 53L, where the eaves portion 53f is located. The electrical continuity processing portions 58 of the coaxial cable 41L at locations on the left and right where there are no eaves portions are also similarly electrically connected by solder 57. The electrical continuity processing may be performed using a crimping tool or the like.

[0033] The joint portion 54L has a shape with small steps in the front-to-back and up-to-down directions. Therefore, the side 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 side bracket 53L is positioned slightly behind and slightly below the central bracket 52, so as to satisfy the layout requirements with other components inside the housing 12. Up to this point, we have explained the side bracket 53L and the joint portion 54L, but the side bracket 53R and the joint portion 54R are symmetrical to the side bracket 53L and the joint portion 54L and have approximately the same configuration.

[0034] 7A, 7B, and 7C are diagrams showing the central bracket 52 of the antenna unit 50, with (a) being a plan view, (b) being a rear view, and (c) being a bottom view. Fig. 8 is a cross-sectional view taken along line VIII-VIII in Fig. 7.

[0035] The central bracket 52 has a front wall 52a, a rear inclined wall 52b, a lower wall 52c, and an upper wall 52d, and is shaped to substantially cover the front, rear, top, and bottom of the coaxial cable 41L. The inclined wall 52b and the lower wall 52c correspond to the rear wall 53d and the lower wall 53e of the side bracket 53L. The upper wall 52d protrudes horizontally rearward from the upper end of the front wall 52a. The upper wall 52d protrudes further rearward than the end of the inclined wall 52b, and this portion corresponds to the rear end of the eaves portion 53f of the side bracket 53L. There is almost no gap between the upper wall 52d and the end of the inclined wall 52b.

[0036] 9 is a cross-sectional view taken along line IX-IX in FIG. 7. As shown in FIG. 9 and FIG. 7(a), two notched openings 59 are formed in the central bracket 52, extending from the front wall 52a to the top wall 52d. The notched openings 59 have slightly deep cutouts 59a at both ends and a slightly deep cutout 59b in the center of the top wall 52d. Cutout 59a is narrow, while cutout 59b is slightly wide. The two notched openings 59 are formed relatively long in the X direction, and in this embodiment, the combined length of the two cutouts accounts for approximately two-thirds of the overall length of the central bracket 52.

[0037] A portion of the sheath of the coaxial cable 41L is cut away to expose the shield, and the exposed electrical continuity processing portions 60 are electrically connected to the central bracket 52 of the bracket 44 by solder 57. The two electrical continuity processing portions 60 are provided in the notches 59b in the cutout opening 59. The X-direction length of the electrical continuity processing portions 56, 58, 60 is, for example, approximately 3 mm. The solder 57 of the electrical continuity processing portions 56, 58, 60 is formed so as not to protrude from the side bracket 53L or the central bracket 52 in cross section. The electrical continuity processing portions 56, 58, 60 are arranged at an appropriate distance from each other in a balanced manner.

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

[0039] An inclined surface 20b is formed around the opening 20a in the plate-shaped member 20, and the key top 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 used to fix the keyboard bracket 18a and the bracket 44, is made of metal, 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 to be the electrical connection processing part 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 in the underside of the inclined surface 20b from approximately the middle to the rear. The keyboard bracket 18a is fixed forward of the rectangular notch 61a, and the bracket 44 is fixed so that the upper wall 52d contacts the top surface 61aa of the rectangular notch 61a. The rear ends of the bezel member 61 and the bracket 44 are substantially flush with each other. There is a small gap between the 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.

[0041] The member 62 attached to the keyboard bracket 18a is a black tape that hides the metal portion, and its rear end 62a is bent to form an L-shape and fits into the rectangular cutout 61a. The member 62 is made up of two pieces. There is a small gap 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. The bottom wall 52c of the bracket 44 is located slightly higher than the keyboard bracket 18a. The top wall 52d of the bracket 44 is located slightly above the keyboard bracket 18a, but not so as to narrow the exhaust window 45a.

[0042] Bracket 44 is aligned along upper edge 45aa and is located within housing 12 at a position that includes the range of opening width W in the Y direction of the short side of the exhaust port due to a layout requirement to make housing 12 thin. Inclined wall 52b of bracket 44 forms an inclined surface that slopes upward toward the rear so as to generally face upper edge 45aa, and therefore does not obstruct the air flow indicated by the arrows, improving cooling efficiency.

[0043] The inclined wall 52b is disposed so as to face the exhaust window 45a at an angle, and covers the coaxial cable 41L so that it is almost invisible through the exhaust window 45a, which is preferable from a design perspective. The notched opening 59 is formed from the front wall 52a to the top wall 52d, so it is not visible from outside the exhaust window 45a. The same applies to the electrical continuity processing part 60 and the solder 57. The coaxial cable 41L is supported by the bracket 44, so it does not sag or accidentally shift. Because the coaxial cable 41L is covered by the bracket 44, it is not exposed to the air flow and does not vibrate.

[0044] In the electronic device 10 according to this embodiment, the coaxial cable 41L is arranged relatively long along the longitudinal direction of the main exhaust port 45, and this portion is covered on the surface with a bracket 44 that has conductivity and electromagnetic shielding properties. Moreover, the shielded portion of the coaxial cable 41L is made conductive to the bracket 44 and is further made conductive to the metal portion of the housing 12 via the bracket 44, thereby improving the electromagnetic shielding performance of the coaxial cable 41L.

[0045] The two fans 30L, 30R are located on either side of the main exhaust port 45 inside the housing 12, and the CPU 27 is located between the two fans 30L, 30R. The CPU 27 is prone to generating electromagnetic noise, and the main exhaust port 45 is located in a position that is susceptible to this influence, but the coaxial cable 41L that has been treated as described above has improved electromagnetic shielding performance and is therefore applicable.

[0046] Bracket 44 is preferably made of a metal plate, which is conductive, has sufficient strength even when relatively thin, and is easy to process. However, depending on the design conditions, bracket 44 may be made of a resin material. In this case, it is recommended to make the surface conductive by metal plating using techniques such as LDS (Laser Direct Structuring), and then connect the plated part to the shield part.

[0047] The present invention is not limited to the above-described embodiment, and can of course be freely modified within the scope of the gist of the present invention. [Explanation of symbols]
