[Effects of the Invention]
[0007] According to the above embodiment of the present invention, the adhesive tape will not interfere with the cables of electronic devices when it is peeled off by pulling. [Brief explanation of the drawing]
[0008] [Figure 1] Figure 1 is a schematic plan view of an electronic device according to one embodiment, viewed from above. [Figure 2] Figure 2 is a plan view showing the rear side of the first enclosure. [Figure 3] Figure 3 is a schematic front view of the first housing with the bezel and display panel removed. [Figure 4] Figure 4 is an enlarged view of the area around the intersection of the first and third edges in Figure 3. [Figure 5]Figure 5 shows the procedure for removing adhesive tape, where (a) shows the first step, (b) shows the second step, (c) shows the third step, and (d) shows the final step. [Modes for carrying out the invention]
[0009] Embodiments of the electronic device according to the present invention will be described in detail below with reference to the drawings. However, the present invention is not limited to these embodiments.
[0010] 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 of this embodiment is a clamshell-type notebook PC, and is configured such that a first housing 12 and a second housing 14 are connected by a hinge 16 so as to be rotatable relative to each other. The first housing 12 is equipped with a display panel 18. The second housing 14 is equipped with a keyboard 20, a touchpad 21, etc., facing the top surface 14a, and is equipped with a motherboard, etc., inside. The electronic device according to the present invention may be other than a notebook PC, for example, a standalone display device, a tablet PC, a mobile phone, a smartphone, or a portable game console.
[0011] Hereinafter, with respect to the electronic device 10, we will use the state in which the first housing 12 is opened from the second housing 14 and the planes of the two are perpendicular to each other (with the angle between housings 12 and 14 set to 90 degrees) as a reference, and from the perspective of a user viewing the display panel 18, the left and right directions will be referred to as the X1 and X2 directions, the up and down directions as the Y1 and Y2 directions, and the depth directions as the Z1 and Z2 directions. The X1 and X2 directions may also be collectively referred to as the X direction, and the Y1 and Y2 directions and the Z1 and Z2 directions may also be referred to similarly.
[0012] The first housing 12 is a flat box-shaped body that is thinner than the second housing 14. The display panel 18 has a display surface 18a facing the Z1 side surface (front 12a) of the first housing 12. The first housing 12 has a housing cover 24 that forms the Z2 side surface (rear 12b) and a bezel member 26 that forms the peripheral edge of the front 12a. The top, bottom, left, and right sides 12c of the first housing 12 are formed by vertical walls 27 that rise from the four peripheral edges of the housing cover 24. The hinge 16 connects the Y2 side edge of the first housing 12 to the Z2 side edge of the second housing 14.
[0013] The display panel 18 is composed of, for example, a liquid crystal display or an organic EL display. The display panel 18 has a structure in which, for example, glass, a liquid crystal layer, and a light guide plate are laminated and the outer edges of each layer are fixed together with double-sided tape or adhesive. The display panel 18 may also be a touch panel type.
[0014] The housing cover 24 is a rectangle in which the Y-direction dimension is smaller than the X-direction dimension when viewed from the front, and the display panel 18 is a rectangle slightly smaller than the housing cover 24. In this application, the edge on the Y1 side is called the first edge 28a, the edge on the Y2 side is called the second edge 28b, the edge on the right side when viewed from the front is called the third edge 28c, and the edge on the left side is called the fourth edge 28d. In other words, the housing cover 24 is a rectangular member having the first edge 28a, the second edge 28b opposite the first edge 28a, and the third edge 28c and fourth edge 28d perpendicular to the first edge 28a and the second edge 28b, and covers the back side of the display panel 18.
[0015] Multiple electronic devices 30 are provided in the central part of the bezel member 26 along the first edge 28a, facing forward. The electronic devices 30 include, for example, a camera, a microphone, and an infrared port. The left and right ends of the bezel member 26 along the second edge 28b are cut out and covered by a cover 31.
[0016] Figure 2 is a plan view showing the rear side of the first housing 12. Near the corner where the first edge 28a and the third edge 28c of the housing cover 24 intersect, there is a small lamp (electronic device) 32 that indicates the power status, etc. The lamp 32 is provided on the inner surface of the housing cover 24, and the light-emitting part 32a is exposed on the outer surface. Because the lamp 32 is in a corner, it is not easily obscured by other objects. The lamp 32 is easily visible from the rear because it is positioned above the first housing 12 when it is open relative to the second housing 14. The distance from the lamp 32 to the first edge 28a and the distance to the third edge 28c are approximately equal, resulting in good design balance. Thus, it is preferable to place the lamp 32 in a corner of the housing cover 24. The lamp 32 is, for example, an LED.
[0017] Figure 3 is a schematic front view of the first housing 12 with the bezel member 26 and display panel 18 removed. Figure 4 is an enlarged view of the area around the intersection of the first edge 28a and the third edge 28c in Figure 3.
[0018] As described above, an electronic device 30 is provided along the first edge 28a of the housing cover 24. Multiple electronic devices 30 are grouped together and mounted as a module 33. The first housing 12 and the second housing 14 are electrically connected by a flat cable 34. The flat cable 34 is, for example, an FPC, but other cables may also be used. The flat cable 34 connects to the second housing 14 at a point slightly to the right of the first housing 12, then slopes towards the center, extends again in the Y1 direction, reaches the vicinity of the first edge 28a, and connects to the module 33.
[0019] In this embodiment, the flat cable 34 branches into a first branch cable 36, a second branch cable 38, and a third branch cable 40. Among these, the first branch cable 36 and the second branch cable 38 reach near the first edge 28a in parallel. The second branch cable 38 is adjacent to the right of the first branch cable 36 and is thinner than the first branch cable 36. The third branch cable 40 further branches from near the tip of the second branch cable 38 and is connected to the lamp 32. The third branch cable 40 is also simply called the cable 40. The cable 40 will be further described later.
[0020] The housing cover 24 and the display panel 18 are fixed by a first adhesive tape 42, a second adhesive tape 44, a third adhesive tape 46, and a fourth adhesive tape 48. These adhesive tapes are double-sided tapes and have the property of being stretchable and peelable, and are called stretch release tapes, stretch double-sided tapes, or stretchable tapes. Such components have the property that they have a high adhesive force in the non-stretched state, but the adhesive force decreases when stretched. Each adhesive tape is basically separate.
[0021] The first adhesive tape 42 includes a first adhesive portion 42a and a first tab 42b. The second adhesive tape 44 includes a second adhesive portion 44a and a second tab 44b. The third adhesive tape 46 includes a third adhesive portion 46a and a third tab 46b. The fourth adhesive tape 48 includes a fourth adhesive portion 48a and a fourth tab 48b. Each adhesive portion is the part with the adhesive effect. Each tab is the part for tensile operation and has no adhesive effect. Each adhesive portion is shown as a dot pattern.
[0022] The second adhesive tape 44 is linear. The second adhesive portion 44a is provided almost along the entire length near the third edge 28c. The second tab 44b extends short from the Y2-side end of the second adhesive portion 44a toward the second edge 28b. The second adhesive portion 44a is between the first adhesive tape 42 and the third edge 28c.
[0023] The first adhesive portion 42a extends from the right vicinity of the module 33 toward the right along the first edge 28a. The first tab 42b comprises a transverse extension portion 42ba that extends a short distance from the end of the first adhesive portion 42a toward the third edge 28c, a longitudinal extension portion 42bb that extends along the third edge 28c to the second edge 28b, and a bent portion 42bc that curves away from the first edge 28a and the third edge 28c between the transverse extension portion 42ba and the longitudinal extension portion 42bb. In other words, the transverse extension portion 42ba and the longitudinal extension portion 42bb are indirectly connected via the bent portion 42bc. As will be described later, a ramp 32 is provided in the inner circumference region of the curve formed by the bent portion 42bc. In other words, the bent portion 42bc follows a path that avoids the ramp 32. However, depending on the arrangement of the ramp 32, the bent portion 42bc may be omitted, and the lateral extension portion 42ba and the longitudinal extension portion 42bb may be directly connected.
[0024] The third adhesive tape 46 is a form of the first adhesive tape 42 in which the bent portion 42bc is omitted, and is provided symmetrically with respect to the first adhesive tape 42. The fourth adhesive tape 48 has the same shape as the second adhesive tape 44, and is provided symmetrically with respect to the fourth adhesive tape 48.
[0025] The tips 42c, 44c, 46c, and 48c of each tab 42b, 44b, 46b, and 48b extend to a position on the second edge 28b that does not overlap with the display panel 18. The tips 42c, 44c, 46c, and 48c are normally covered by the cover 31, but by removing the cover 31, they are exposed and can be pulled. For space saving purposes, the tips 42c and 44c, and the tips 46c and 48c may overlap.
[0026] As described above, the ramp 32 is located within the range avoided by the bent portion 42bc, specifically, part or all of it is within the extended width of the lateral extension portion 42ba and within the extended width of the vertical extension portion 42bb. This allows the ramp 32 to be properly positioned in the corner of the housing cover 24.
[0027] The cable 40 consists of a short first portion 40a connected in a crank shape to the second branch cable 38, a long second portion 40b extending laterally, and an inverted U-shaped third portion 40c connected to the lamp 32. The second portion 40b connects the first portion 40a and the third portion 40c. The cable 40 is not adhered to the housing cover 24, at least with respect to the third portion 40c and its vicinity. The second portion 40b extends in region A1 (see Figure 4) on the Y2 side (the side of the second edge 28b) from the first adhesive portion 42a and the laterally extending portion 42ba, and on the X1 side (the side of the fourth edge 28d) from the vertically extending portion 42bb. In this embodiment, the second portion 40b is on the Y2 side (the side of the second edge 28b) from the first adhesive portion 42a and is adjacent to and parallel to the first adhesive portion 42a. Region A1 corresponds to the lower left side of the intersection point C of the extension line L1 of the transversely extending portion 42ba and L2 of the longitudinally extending portion 42bb in Figure 4. In this embodiment, due to the fact that the third cable 40 branches off from the second cable 38 and its positional relationship with the module 33, the second portion 40b is routed in region A1 rather than region A2 (see Figure 4). Region A2 is on the Y1 side (closer to the first edge 28a) of the first adhesive portion 42a and the transversely extending portion 42ba, and corresponds to the upper left side of the intersection point C in Figure 4.
[0028] The third section 40c is a bypass section that bypasses the lateral extension 42ba and the bent section 42bc of the first tab 42b to area A2 and connects to the ramp 32. The stacking configuration in this section is in the order of housing cover 24, first tab 42b, third section 40c, and display panel 18. In other words, in the assembly process of the electronic device 10, the adhesive tapes 42, 44, 46, and 48 are already attached to the housing cover 24, the flat cable 34 including the cable 40 is placed on top of this, and then the display panel 18 is attached. The third section 40c of the cable 40 does not need to be passed under the first tab 42b, and can be placed directly over the first tab 42b, thus reducing the working time.
[0029] In this embodiment, the third portion 40c extends not only to the transversely extending portion 42ba but also to a portion of the bent portion 42bc, but basically crosses the first tab 42b in the portion including the transversely extending portion 42ba. The cable 40 is routed so as not to touch the first adhesive portion 42a and the second adhesive portion 44a.
[0030] Figure 5 shows the procedure for removing the adhesive tapes 42 and 44, where (a) shows the first stage, (b) shows the second stage, (c) shows the third stage, and (d) shows the final stage. When removing the adhesive tapes 42 and 44, remove the cover 31 to expose the tips 42c and 44c.
[0031] As shown in Figure 5(a), first pull the tip 44c towards you to remove the second adhesive tape 44. As shown in Figure 5(b), grasp the tip 42c and pull it up to the upper right. The longitudinally extended portion 42bb of the first tab 42b is pulled out from the gap between the housing cover 24 and the display panel 18.
[0032] As shown in Figure 5(c), the longitudinally extending portion 42bb is oriented along the X direction, and the first adhesive tape 42 has a slightly wavy shape from the transversely extending portion 42ba to the bent portion 42bc, but the first adhesive portion 42a and the first tab 42b are almost straight along the X direction. In this case, the first adhesive tape 42 mainly has the bent portion 42bc inside the U shape formed by the third portion 40c, so that no undue force is applied to the third portion 40c and the ramp 32.
[0033] When the first tab 42b is pulled towards X2, the adhesive force of the first adhesive portion 42a decreases, and the first adhesive portion 42a and the laterally extended portion 42ba are pulled out through the inside of the U-shape formed by the third portion 40c. Even at this time, no excessive force is applied to the third portion 40c and the lamp 32. As shown in Figure 5(d), the cable 40 and the lamp 32 are correctly maintained in their original positions even with the first tab 42b pulled out. The removal of the fourth adhesive tape 48 is the same as that of the second adhesive tape 44, and the removal of the third adhesive tape 46 is the same as that of the first adhesive tape 42. Once each of the adhesive tapes 42, 44, 46, and 48 is removed, the display panel 18 can be removed from the housing cover 24.
[0034] Thus, in the electronic device 10 according to this embodiment, the cable 40 bypasses the first tab 42b from region A1 to region A2, including the lateral extension portion 42ba, and is connected to the lamp 32. As shown in Figures 5(b) to (d), the cable 40 does not interfere with the first adhesive tape 42 when it is pulled off. When the display panel 18 is reinstalled, the lamp 32 is maintained in the correct position and does not need to be reattached or replaced. In addition, the first adhesive portion 42a of the first adhesive tape 42 can be positioned in a predetermined location by passing it under the second portion 40b of the cable 40.
[0035] As described above, the lamp 32 is located within the extended width of the extended portion 42aa and within the extended width of the vertically extended portion 42bb. However, even if it is located in region A3 on the extension line L1 of the horizontally extended portion 42ba or Y1 side of said extension line L1, and on the extension line L2 of the vertically extended portion 42bb or X2 side (right side in Figure 4) of said extension line L2, interference with the first adhesive tape 42 can be avoided by the third portion 40c of the cable 40 bypassing the first tab 42b from region A1 to region A2, including the horizontally extended portion 42ba. As shown by the dashed line in Figure 4, if the lamp 32 is in region A1 or region A2, the bypass route by the third portion 40c is unnecessary. The destination of the cable 40 is not limited to the lamp 32; it may also be an electronic device such as a microphone, sensor, or display.
[0036] 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]
