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

[0004] However, antenna elements and antenna modules are sometimes connected via coaxial cables. Although coaxial cables have electromagnetic shielding properties, their performance may not be fully adequate when the coaxial cable is lengthened to facilitate layout or placed near components that generate electromagnetic noise.

Detailed Implementation

[0021] Hereinafter, embodiments of the invention described under the given name will be described in detail with reference to the accompanying drawings. However, the invention is not limited to these embodiments.

[0022] Figure 1 This is a schematic top view obtained from above, showing an electronic device 10 according to one embodiment. For example... Figure 1 As shown, the electronic device 10 in this embodiment is a flip-type laptop PC. The electronic device 10 has a structure in which the cover 11 and the housing 12 are connected by a hinge 14 to allow relative rotation. In this embodiment, a laptop PC electronic device 10 is exemplified, but in addition to a laptop PC, the electronic device may also be a tablet PC, a smartphone, or a portable game console.

[0023] 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.

[0024] The housing 12 is a thin, flat box. The keyboard device 18 and the touchpad 19 face the upper surface 12a of the housing 12. Hereinafter, regarding the housing 12 and the various components mounted on the housing 12, based on the posture of the operator operating the keyboard device 18, the width direction (left and right) of the housing 12 will be referred to as X1 and X2 directions, the depth direction (front and back) of the housing 12 will be referred to as Y1 and Y2 directions, and the thickness direction (up and down) of the housing 12 will be referred to as Z1 and Z2 directions. Sometimes, the X1 and X2 directions are collectively referred to as the X direction, and the Y1 and Y2 directions and the Z1 and Z2 directions are also sometimes referred to as the Y direction and the Z direction. The above directions are determined for ease of explanation, and of course, they can vary depending on the usage state or setting posture of the electronic device 10. In this application, for a pair of left and right components, the reference numeral for the left component is sometimes marked "L", and the reference numeral for the right component is marked "R".

[0025] The housing 12 can be constructed from a plate-like member 20 forming an upper surface 12a, a cover member 21 forming a bottom surface 12b, and a vertical wall member 22 forming side surfaces 12c around the perimeter. The rear portion of the side surfaces 12c is designated as the rear side surface 12ca. The plate-like member 20 has a large rectangular opening 20a for mounting the keyboard device 18. The vertical wall member 22 occupies the majority of the side surfaces 12c of the housing 12, but the wall portion 39c described later (see reference)... Figure 5) also occupies a part. The plate-like member 20 and the cover member 21 are formed by stamping a metal material, so that a high texture can be obtained. Almost all of the plate-like member 20 and the cover member 21 are metal parts. The vertical wall member 22 is made of a resin material, but it can also be a metal material integrated with the plate-like member 20 or the cover member 21. The plate-like member 20 and the cover member 21 do not have radio wave permeability, but the wall portion 39c has radio wave permeability.

[0026] The hinge 14 is provided in a concave hinge arrangement groove 12d formed in the rear side surface 12ca of the housing 12 to connect the housing 12 and the lid 11. The hinge 14 is, for example, a structure in which hinge shafts that will become rotation shafts are respectively supported at both ends in the length direction of the hinge housing 14a. The hinge 14 of the present embodiment is configured in a so-called single rod shape (Japanese original text: ワンバー形状) in which the hinge housing 14a extends along the length direction of the hinge arrangement groove 12d. In the hinge 14, the hinge housing 14a rotates integrally with the lid 11 and descends obliquely backward. The hinge 14 is a structure that obtains the rotation angle of the lid 11 in this way, that is, a so-called drop-down structure (Japanese original text: ドロップダウン構造). The structure of the hinge 14 can also be a structure other than the above.

[0027] Figure 2 is a view obtained by removing the cover member 21 and observing the inside of the housing 12 from the lower surface side. As Figure 2 shown, for the inside of the housing 12, the motherboard 25 occupies almost the rear half, and the battery 26 occupies almost 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 in the rear and sufficiently separated left and right on the motherboard 25. The fans 30L and 30R are provided at left and right positions separated by a main exhaust port 45 and sub-exhaust ports 46L and 46R described later. The fans 30L and 30R are respectively arranged in the cutout portions of the motherboard 25, and air supply ports 30a are formed at the edges on the opposite sides, and can supply air to the opposite side and supply air to the upper and lower surfaces of the motherboard 25. The fans 30L and 30R suck air from an air intake port (not shown) formed in the cover member 21, etc.

[0028] On the motherboard 25, the CPU 27 is mounted at a substantially middle position between the two fans 30L and 30R. The heat dissipation member 31 extends almost without a gap between the fans 30L and 30R, and is pressed by a rear leaf spring 32 and a front leaf spring 33 to contact the CPU 27. The heat dissipation member 31 absorbs and diffuses the heat of the CPU 27.

[0029] The front ends of the air outlets 30a of fans 30L and 30R are blocked by sponges 34. The sponges 34 are flat U-shaped with a slight forward protrusion to surround the heat dissipation component 31 and the leaf spring 33. A pair of short sponges 35 extend from near the rear ends of the air outlets 30a of fans 30L and 30R toward each other. The sponges 35 block approximately half of the space between fans 30L and 30R and the leaf spring 32. The sponges 34 and 35 are fixed to the mother plate 25. On fans 30L and 30R, sponges 36 are provided from the air outlets 30a to the rear side. The sponges 34, 35, and 36 block the space between themselves and the cover component 21. The air from fans 30L and 30R is discharged from the main exhaust port 45 located in the center of the rear side and the auxiliary exhaust ports 46L and 46R on both sides, which can efficiently cool the CPU 27.

[0030] Antenna module 28 and antenna elements 39L and 39R, described in the next paragraph, correspond to WWAN, WLAN, etc. Antenna module 28 is adjacent to the front side of fan 30R. Two terminals 28aa and 28ab are provided at the right end of antenna module 28. Memory module 29 is located slightly in front of fan 30L. Board connector 37R is provided between fan 30R and leaf spring 32, and board connector 37L is provided between fan 30L and leaf spring 32. Flat cables 38L and 38R are connected to board connectors 37L and 37R, respectively, and extend towards cover 11.

[0031] Two antenna elements 39L and 39R are disposed at the rear end of housing 12. Antenna element 39R is adjacent to the rear side of fan 30R, and antenna element 39L is adjacent to the rear side of fan 30L. Plate 40L is arranged side-by-side to the right of antenna element 39L, and plate 40R is arranged side-by-side to the left of antenna element 39R. Plates 40L and 40R are used to appropriately adjust the path length of flat cables 38L and 38R.

[0032] Antenna element 39L is connected to terminal 28aa of antenna module 28 via coaxial cable 41L. Antenna element 39R is connected to terminal 28ab of antenna module 28 via coaxial cable 41R. Coaxial cable 41R extends slightly to the right from terminal 28ab and then rearwards, passing through the right side of fan 30L to reach antenna element 39R. Coaxial cable 41L extends slightly to the right from terminal 28aa and then rearwards almost parallel to coaxial cable 41R, further extending to the left along the rear surface 12ca, which is the rear edge of housing 12, to reach antenna element 39L.

[0033] Therefore, coaxial cable 41L is longer than coaxial cable 41R. Except for length, coaxial cables 41L and 41R are identical cables, having a conductor, insulator, shield, and sheath arranged concentrically radially from the center. The ends 41La and 41Ra are connected to terminals 28aa and 28ab. The shield is grounded. Coaxial cables 41L and 41R have a moderate length allowance on the left side of fan 30L and are secured by two clips 42. Coaxial cables 41L and 41R pass through a relatively narrow section between fan 30L and element 43. The portion of coaxial cable 41L along the rear surface 12ca of housing 12 is almost entirely covered by bracket 44. Antenna element 39L, coaxial cable 41L, and bracket 44 constitute antenna unit 50 (see reference). Figure 4 ).

[0034] Figure 3 This is a schematic diagram of the rear surface 12ca of the housing 12. As described above, the majority of the side surface 12c, including the rear surface 12ca, is formed by the vertical wall member 22. A main exhaust port 45 and two secondary exhaust ports 47L and 47R are formed on the vertical wall member 22 of the rear surface 12ca. The main exhaust port 45 is configured as a plurality of (in this case, four) relatively large exhaust windows 45a arranged side-by-side in the center of the cover member 21. The secondary exhaust ports 47L and 47R are formed to the left and right of the main exhaust port 45, and are composed of a plurality of (in this case, three) relatively small exhaust windows 47a. Mesh 48 is provided in the exhaust windows 45a and 47a. The mesh 48 is large enough not to obstruct exhaust, and allows some visibility of the interior of the housing 12 from the outside through the mesh 48.

[0035] Small pieces 64L and 64R covering the hinge 14 are provided at both ends of the cover component 21. Antenna elements 39L and 39R are arranged in the recesses 49L and 49R between the small pieces 64L and 64R and the secondary exhaust port 47. The secondary exhaust ports 47L and 47R are due to the sponge 35 (refer to...) Figure 2 The board connectors 37L and 37R are located nearby and have relatively low ventilation. Most of the air supplied from fans 30L and 30R is exhausted through the main exhaust port 45. The main exhaust port 45 is roughly positioned opposite the leaf spring 32. (Refer to...) Figure 2 It is located between board connectors 37L and 37R and secondary exhaust ports 47L and 47R.

[0036] Antenna unit 50 will be described below. As described above, antenna unit 50 consists of antenna element 39L, coaxial cable 41L and bracket 44, and is pre-assembled into a unit form, which can be handled as a component in the assembly process of electronic device 10, and has good workability.

[0037] Figure 4 This is a 3D view of antenna element 50. Figure 4 , Figure 5 , Figure 7 The arrows indicating orientation are based on the orientation of bracket 44. Bracket 44 is composed of a straight central bracket 52 and side brackets 53L and 53R. The central bracket 52, side brackets 53L and 53R are sequentially arranged in the longitudinal X direction, intersecting the main exhaust port 45 and the auxiliary exhaust port 47L and 47R. The central bracket 52 and the side brackets 53L and 53R are connected by joints 54L and 54R. Bracket 44, including the joints 54L and 54R, is integrally constructed by bending a single metal plate and provides a shielding effect. Bracket 44 may also undergo surface treatments such as nickel plating. Bracket 44 does not have an insulating coating, but it is conductive on the surface, at least during the conductive treatment described later.

[0038] Figure 5 This diagram shows the side bracket 53L and antenna element 39L in antenna unit 50, wherein... Figure 5 (a) is a top view. Figure 5 (b) is the rear view. Figure 5 (c) is a bottom view. Regarding bracket 44, Figure 5 (c) and the following Figure 6 (c) refers to the assembly with the housing. Figure 2 Same orientation. In Figure 5 In the middle, the antenna element 39L is combined with Figure 2 The state is shown when it is offset by 90 degrees.

[0039] Antenna element 39L includes: an element body 39a, fixing plates 39b disposed on its left and right sides, and a wall portion 39c erected at the rear. The element body 39a is connected to a coaxial cable 41L. The fixing plates 39b are provided with threaded holes 39ba and positioning holes 39bb. The wall portion 39c forms part of the upright wall component 22. The wall portion 39c is made of resin material and has radio wave permeability. Furthermore, antenna element 39R is symmetrical to antenna element 39L and has almost the same shape.

[0040] A fixing piece 53a is formed at the left end of the side bracket 53L near the antenna element 39L. A fixing piece 53b is formed in the connection part of the connector 54L with the side bracket 53L. The fixing pieces 53a and 53b are arranged horizontally. A plate 40L (see reference) is arranged between the fixing pieces 53a and 53b. Figure 2 ).

[0041] Threaded holes 53aa and 53ba are formed approximately in the center of the fixing plates 53a and 53b. Threaded holes 53aa and 53ba overlap during housing assembly and are fastened together by a single screw to the frame component 61 (described later). Figure 10The specified stud is fixed to the specified stud of the frame member 61 via a threaded hole 53ba. A positioning notch 53ab is formed on the fixing plate 53a. The positioning notch 53ab overlaps with the positioning hole 39bb during housing assembly and is positioned by a specified pin of the frame member 61. A positioning hole 53bb is formed on the fixing plate 53b slightly towards X1 and is positioned by a specified pin of the frame member 61. Hooks 53ac and 53bc are wound into a sleeve shape from the fixing plates 53a and 53b to fix the coaxial cable 41L. Thin and short eaves 53ad and 53bd are provided on the fixing plates 53a and 53b along the coaxial cable 41L.

[0042] Figure 6 yes Figure 5 The cross-sectional view along lines VI-VI. The side bracket 53L has a rear wall 53d, a lower wall 53e, and an eaves 53f, and is shaped to cover the rear and lower sides of the coaxial cable 41L, with openings on the front and upper sides. The rear wall 53d and the lower wall 53e are in almost contact with the coaxial cable 41L. The eaves 53f protrudes horizontally from the end of the rear wall 53d. The eaves 53f is provided between the eaves 53ad and 53bd (see reference). Figure 5 (a)). The eaves 53f, 53ad, and 53bd abut against the top surface 61aa (see below). Figure 10 Thus, the 53L side bracket is stable.

[0043] A portion of the sheath of the coaxial cable 41L is cut away to expose the shielding portion, and the exposed conductive portion 56 is made conductive with the side bracket 53L of the bracket 44 via solder 57. Figure 5 As shown, the continuity processing section 56 is located approximately in the center of the side bracket 53L at the portion with the eaves 53f. In the coaxial cable 41L, the continuity processing section 58, which is separated on the left and right sides and lacks an eaves, is also similarly made continuous by solder 57. Continuity processing can also be performed using a crimping device or the like.

[0044] The connector 54L has a shape with small step differences in front-to-back and top-to-bottom. Therefore, the side bracket 53L and the central bracket 52 are located at slightly offset positions in front-to-back and top-to-bottom. Specifically, the side bracket 53L is located slightly behind and slightly below the central bracket 52, and satisfies the layout requirements with other components within the housing 12. The side bracket 53L and connector 54L have now been described. The side bracket 53R and connector 54R have a structure that is symmetrical and almost identical to the side bracket 53L and connector 54L.

[0045] Figure 7 This is a diagram showing the central bracket 52 in antenna element 50, wherein, Figure 7 (a) is a top view. Figure 7 (b) is the rear view. Figure 7 (c) is a bottom view. Figure 8 yes Figure 7 The sectional view along lines VIII to VIII.

[0046] The central bracket 52 has a front wall 52a, a rear inclined wall 52b, a lower wall 52c, and an upper wall 52d, forming a shape that almost completely covers the front and rear, and 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 in 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 53f in the side bracket 53L. There is almost no gap between the ends of the upper wall 52d and the inclined wall 52b.

[0047] Figure 9 yes Figure 7 A sectional view along lines IX to IX in the diagram. (Example) Figure 9 and Figure 7 As shown in (a), two cutouts 59 are formed in the central bracket 52 from the front wall 52a to the upper wall 52d. Each cutout 59 has a slightly deeper cutout 59a at both ends and a slightly deeper cutout 59b in the central upper wall 52d. The cutout 59a is narrower, and the cutout 59b is slightly wider. The two cutouts 59 are relatively long in the X direction; in this embodiment, the combined length of the two cutouts accounts for approximately 2 / 3 of the total length of the central bracket 52.

[0048] A portion of the sheath of the coaxial cable 41L is removed to expose the shielding. Two exposed conductive sections 60 are connected to the central bracket 52 of the bracket 44 via solder 57. The two conductive sections 60 are located in the cut-in portion 59b within the cut-out opening 59. The X-direction length of the conductive sections 56, 58, and 60 is, for example, approximately 3 mm. Furthermore, the solder 57 of the conductive sections 56, 58, and 60 is formed so that it does not extend beyond the side bracket 53L or the central bracket 52 in cross-section. The conductive sections 56, 58, and 60 are appropriately separated from each other and are arranged in a balanced manner.

[0049] Figure 10 This is a schematic cross-sectional view of the rear portion of the housing 12. Figure 10 The cover 11 is omitted. Figure 10 In the figure, reference numeral 18a is the keyboard tray of the keyboard device 18, and reference numeral 18b is the key top. Figure 10 The three hollow arrows in the diagram illustrate the airflow from fans 30L and 30R to exhaust vent 45a. One arrow indicates airflow through the narrow gap between motherboard 25 and keyboard tray 18a, where the flow rate is relatively small. The other two arrows indicate airflow through the gap between motherboard 25 and bottom surface 12b, where the flow rate is relatively large.

[0050] 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 frame member 61 is fixed to the inner surface of the plate-shaped member 20 around the opening 20a. The frame member 61, made of metal, is used to fix the keyboard tray 18a and the tray 44, and is in communication with the plate-shaped member 20. Furthermore, as described above, the tray 44 is fixed to the studs of the frame member 61, and is in communication with the housing 12 via the frame member 61. That is, the frame member 61 and its studs can be considered as the communication processing part of the tray 44.

[0051] The frame member 61 is disposed along the front and rear of the inclined surface 20b, and a rectangular cutout 61a is formed on the lower surface from approximately the middle of the inclined surface 20b to the rear. The keyboard tray 18a is fixed at a position forward of the rectangular cutout 61a, and the tray 44 is fixed such that its upper wall 52d contacts the top surface 61aa of the rectangular cutout 61a. The rear ends of the frame member 61 and the tray 44 are almost flush. The gap between the rear ends of the frame member 61 and the tray 44 and the upper edge 45aa, which serves as one edge of the vent 45a, is small.

[0052] The component 62, mounted on the keyboard tray 18a, is a black adhesive tape concealing the metal part. Its rear end 62a bends into an L-shape and enters the rectangular cutout 61a. Component 62 consists of two sheets of adhesive tape. 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 tray 44, are small. The lower wall 52c of the tray 44 is positioned slightly higher than the keyboard tray 18a. The upper wall 52d of the tray 44 is positioned slightly upwards without narrowing the vent 45a.

[0053] The bracket 44, along its upper edge 45aa, is positioned within the housing 12 within the range of the opening width W in the Y direction, including the short side of the exhaust port, due to the layout requirement of thinning the housing 12. The inclined wall 52b of the bracket 44 is formed with an upward inclined surface towards the rear side, generally toward the upper edge 45aa, thus not obstructing the airflow indicated by the arrow and improving cooling efficiency.

[0054] The inclined wall 52b is configured to be angled relative to the vent 45a, covering the coaxial cable 41L in a way that makes it virtually invisible through the vent 45a, which is preferable in terms of appearance design. The cutout opening 59 extends from the front wall 52a to the upper wall 52d, and is therefore not visible from outside the vent 45a. The same applies to the conductive treatment section 60 and the solder 57. The coaxial cable 41L is supported by the bracket 44, thus preventing it from drooping or unintentionally shifting. The coaxial cable 41L is covered by the bracket 44, thus preventing contact with airflow and vibration.

[0055] In the electronic device 10 of this embodiment, the coaxial cable 41L is provided to be relatively long along the length direction of the main exhaust port 45, but this part is covered by a bracket 44 with conductive and electromagnetic shielding properties on its surface. Moreover, the shielding part of the coaxial cable 41L is conductively connected to the bracket 44, and is conductively connected to the metal part of the housing 12 via the bracket 44, thereby improving the electromagnetic shielding performance of the coaxial cable 41L.

[0056] Two fans, 30L and 30R, are positioned inside the housing 12, separated from the main exhaust port 45. 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 a location susceptible to this. However, the electromagnetic shielding performance of the coaxial cable 41L, which has undergone the aforementioned treatment, is improved, thus making it suitable for use.

[0057] The bracket 44 is made of a metal plate, which is conductive, has sufficient strength even when relatively thin, and is easy to process, making it preferred. However, the bracket 44 can also be made of resin material depending on the design requirements. In this case, the surface can be made conductive by metal plating such as LDS (Laser Direct Structuring), and the plated part and the shielding part can be made conductive.

[0058] This invention is not limited to the above-described embodiments, and can of course be freely modified without departing from the spirit of this invention.
