Description

The present invention relates to an electronic device including a display.

In an electronic device such as a notebook PC, for example, as shown in Patent Document 1, a first housing on which a display is mounted and a second housing on which a motherboard is mounted are connected by a hinge. In the electronic device described in Patent Document 1, the wiring member connecting the first housing and the second housing is in the shape of a thin wire, and is arranged along the rotation axis of the hinge.

Japanese Patent No. 6698144

By the way, in the configuration of Patent Document 1, the substrate for controlling the display (display substrate) is housed inside the bezel member of the first housing. Therefore, the bezel member becomes wider by the amount of the display board, and the appearance quality deteriorates. Therefore, it is conceivable to store the display board in the second housing and connect the display and the display board with a flexible board extending from the first housing to the second housing.

Since the flexible substrate has a certain width and it is difficult to arrange the flexible substrate along the rotation axis of the hinge as in Patent Document 1, the flexible substrate is arranged so as to cross between the first housing and the second housing. In this case, it is desirable to provide a cover between the first housing and the second housing so that the flexible substrate is not visible to the user. The cover is fixed to, for example, the first housing.

However, in such a cover, when the first housing and the second housing rotate relatively, a part of the cover may come into contact with the flexible substrate and apply pressure while bending, and the number of rotations may be applied. There is a concern that the life of the flexible substrate may be shortened due to repeated stress.

The present invention has been made in view of the above problems, and provides an electronic device in which a flexible substrate extending from a first housing to a second housing is difficult to be visually recognized by a user and the life is not shortened. The purpose is.

In order to solve the above-mentioned problems and achieve the object, the electronic device according to the aspect of the present invention is an electronic device, which is the first housing, the second housing, and the first housing. A hinge for relatively rotatably connecting the second housing, a display provided in the first housing, a printed circuit board provided in the second housing, and the display and the printed circuit board. The first housing includes a flexible substrate to be connected, and the first housing rotates coaxially with the hinge by a rotational operation with respect to the second housing, and the rotating body includes a rotating body through which the flexible board is inserted. The present invention comprises a first opening for guiding the flexible substrate to the display, a second opening for guiding the flexible substrate to the printed circuit board, and a substrate hole through which the flexible substrate passes. In the passing region, the flexible substrate is provided with a protective sheet that imparts bending elastic urging force in a direction of returning to a flat surface in the region passing through the second opening.

The flexible substrate in the above electronic device passes through the substrate hole of the rotating body and is difficult for the user to see. Further, since the flexible substrate is provided with a protective sheet, it is possible to prevent a part of the rotating body from coming into direct contact with the flexible substrate. Further, since the protective sheet applies a bending elastic urging force to the printed circuit board in the direction of returning to a flat surface, it is possible to prevent excessive bending and reduce stress. In this way, the flexible substrate can be appropriately protected and the life can be prevented from being shortened.

When the flexible substrate abuts on both edges of the second opening and bends due to the rotational operation of the first housing and the second housing, the flexible substrate is bent at a steeper angle. The protective sheet may be provided on the facing surface. This makes it possible to more appropriately protect the flexible substrate.

In a storage form in which the first housing and the second housing are laminated to each other with one side facing each other, the substrate hole extends in the stacking direction of the first housing and the second housing. The rotating body has a first half body on the side facing the second housing and a second half body on the opposite side across the substrate hole, and the protective sheet has a protective sheet. It may be provided on the surface of the flexible substrate facing the first half body. As a result, the flexible substrate is covered with the first half body until the first housing rotates from the 0 degree position of the storage form to the predetermined angle of the usage form, and the end portion of the first half body is protected. The flexible substrate can be protected from coming into contact with the sheet.

In the second housing, the flexible substrate has first and second folded portions that are arranged in order and curved in opposite directions to each other, and the flexible substrate is located on the outer peripheral side in the first folded portion. The second folded portion has a connection portion to the printed circuit board on the surface located on the inner peripheral side, the second housing has a keyboard on the upper surface, and the first housing is on the rear side surface. The flexible substrate is connected via the hinge, and the flexible substrate is inserted forward into the second housing from a housing opening formed on the rear side surface of the second housing. The first folded portion is formed by folding back in an arc shape downward and backward, and the second folded portion is formed by folding back in an arc shape further downward and forward. The printed circuit board is relatively fixed to the upper cover material forming the upper surface of the second housing, and the connected portion to which the connecting portion of the flexible substrate is connected is provided downward. The flexible substrate may be provided with the connection portion facing upward.

A guide plate may be provided that projects to the inner peripheral side of the first folded portion through the outer peripheral side of the second folded portion. The flexible substrate is appropriately guided by such a guide plate. Further, even if the flexible substrate is bent by the guide plate and the rotating body, the protective sheet prevents excessive bending.

If the protective sheet is made of stainless steel, it is suitable because it is thin and has an appropriate elasticity.

According to the above aspect of the present invention, the flexible substrate extending from the first housing to the second housing is difficult to be visually recognized by the user, and the life is not shortened.

In FIG. 3, the second housing 14 is shown upside down, and the first housing 12 is not shown.

As shown in FIGS. 2 to 4C, the electronic device 10 accommodates the display board 30 and the touch panel board 31 as a printed circuit board (PCB) for controlling the display 18 in the second housing 14. There is.

The display board 30 is a sub-board for controlling the image display on the display unit 18a. The display board 30 is connected to the motherboard 26, and other subboards described later are also connected to the motherboard 26. The display board 30 is electrically connected to the display unit 18a via the flexible board 32 extending between the housings 12 and 14. The flexible substrate 32 is used, for example, in a set of two arranged side by side.

The touch panel board 31 is a sub-board for controlling the touch panel unit 18b. The touch panel board 31 converts an analog signal based on the touch operation detected by the touch panel unit 18b into a predetermined digital signal and transmits the analog signal to the motherboard 26. The touch panel substrate 31 is electrically connected to the touch panel portion 18b via a flexible substrate 33 extending between the housings 12 and 14. The flexible substrate 33 is used, for example, in a set of two arranged side by side.

The boards 30 and 31 are fixed to the inner surface of the upper cover material 20 at the rear portion of the second housing 14 via a predetermined bracket or the like, and are horizontally installed at a position close to the inner surface of the lower cover material 21 (. See FIG. 4A). The flexible substrates 32 and 33 are flexible printed circuits (FPCs) formed thinly and flexibly by using, for example, a flexible insulating film.

As shown in FIGS. 4A to 4C, a hinge mounting portion 34 is provided on the lower side surface (rear side surface) 12c of the first housing 12. The hinge mounting portion 34 is a portion that projects vertically from the front surface 12a. The hinge mounting portion 34 is a rotating body that rotates coaxially with the hinge 16 when the first housing 12 rotates with respect to the second housing 14. The hinge mounting portion 34 has a jaw shape consisting of a second half body 42, which is a portion forming the lower side surface 12c of the back cover material 28, and a first half body 44, which is a portion protruding from the lower edge portion of the frame wall 29. It is formed and extends in the left-right direction. The frame wall 29 is a member having a small width that protrudes from the end of the first housing 12 in a direction orthogonal to the display 18. The tip side of the hinge mounting portion 34 is arranged in the concave portion 14d of the second housing 14, and is rotatable in the concave portion 14d. The flexible boards 32 and 33 are pulled out of the first housing 12 through the slit-shaped board hole 34a penetrating the hinge mounting portion 34, and then pulled into the second housing 14 through the concave portion 14d. There is. The first half body 44 and the second half body 42 also serve as a cover for covering the flexible substrate 32 (33).

In the second housing 14, the flexible substrate 32 (33) first extends forward from the vicinity of the inner surface of the lower cover material 21 to the vicinity of the inner surface of the upper cover material 20 while extending diagonally upward. Subsequently, the flexible substrate 32 (33) is folded back twice from the top to the bottom to draw an S-shaped portion 36, and then extends forward again along the inner surface of the lower cover material 21.

The S-shaped portion 36 is on a trajectory in which the flexible substrate 32 (33) extends from the display 18 toward the substrate 30 (31), that is, from the display 18 side to the substrate 30 (31) side of the flexible substrate 32 (33). It is formed by two folded portions 36a and 36b which are provided side by side in order and curved in opposite directions. The folded-back portion (first folded-back portion) 36a on the side closer to the display 18 is folded back in a substantially semicircle from the forward direction to the downward and backward directions. The folded-back portion (second folded-back portion) 36b on the side close to the substrate 30 (31) is folded back in a substantially semicircle from the rearward direction to the downward and forwardward direction at the exit of the folded-back portion 36a.

In the second housing 14, the front wall forming the concave portion 14d is formed of a corrugated plate (guide plate) 14e. The corrugated plate 14e is a corrugated plate portion extending diagonally upward from the inner surface of the lower cover material 21 to the vicinity of the inner surface of the upper cover material 20 and extending forward. That is, the corrugated plate 14e has a shape that passes through the outer peripheral side of the folded-back portion 36b and projects to the inner peripheral side of the folded-back portion 36a, and guides the flexible substrate 32 (33). The corrugated plate 14e forms a gap through which the flexible substrate 32 (33) passes between the upper end thereof and the inner surface of the upper cover material 20. The corrugated plate 14e has a cross-sectional shape that follows the shape of the S-shaped portion 36, and can maintain the shape of the S-shaped portion 36 without hindering the movement of the flexible substrate 32 (33).

The flexible substrate 32 (33) has a connection portion 32a (33a) to the substrate 30 (31) on the surface 38 located on the outer peripheral side of the arc in the folded portion 36a and located on the inner peripheral side of the arc in the folded portion 36b. .. That is, the surface 38 is the upper surface in the portion where the connecting portion 32a (33a) is provided. The connecting portion 32a (33a) is a connector terminal connected to the connected portion 30a (31a) provided on the lower surface of the substrate 30 (31). The connecting portion 32a (33a) is installed facing upward from the surface 38. Reference numeral 32b (33b) in FIGS. 2 and 3 is a support plate for fixing the connection portion 32a (33a) to the flexible substrate 32 (33).

The hinge mounting portion 34, the substrate hole 34a, and the peripheral portion thereof will be further described.

When the 0-degree posture shown in FIG. 4A is used as a reference, the hinge mounting portion 34 has the first half body 44 on the side facing the second housing 14 across the substrate hole 34a, and the second half body 42 on the opposite side. It has become. The electronic devices 10 in the 0-degree posture are in a storage form in which the front surface 12a of the first housing 12 faces the upper surface 14a of the second housing 14 and is laminated with each other. In this storage mode, the substrate hole 34a extends in the stacking direction of the first housing 12 and the second housing 14, and one end thereof is a first opening 34aa communicating with the inside of the first housing 12. The other end is the second opening 34ab. The second opening 34b faces the rear side surface 14c of the second housing 14 in response to the rotational operation of the first housing 12.

The cross section of the first half body 44 has an arc shape whose side facing the second housing 14 is convex. The cross section of the second half body 42 has a convex arc shape on the side opposite to the side facing the first half body 44. The first half body 44 and the second half body 42 are arranged so that the extension lines of the respective arc edges are continuous so as to sandwich the first opening 34aa. The second half body 42 has an arc shape larger than that of the first half body 44, and rotates in the concave portion 14d as the first housing 12 rotates (see FIGS. 4B and 4C).

The surface of the first half body 44 facing the substrate hole 34a forms an inclined surface 44a, and the second opening 34ab has a shape that expands in the opening direction. A convex portion 42a is formed in the vicinity of the second opening 34ab in the second half body 42 to support the flexible substrates 32 and 33 in an appropriate direction (see FIG. 4C).

The flexible substrate 32 (33) is provided with a protective sheet 46 on a surface facing the end portion 44b of the first half body 44 in a region passing through the second opening portion 34ab. The protective sheet 46 is a sheet that becomes flat when no load is applied, and is an elastic material that imparts bending elastic urging force in a direction of returning to a flat surface in a bent state. The protective sheet 46 is preferably made of a metal foil such as stainless steel because it is thin and has an appropriate elasticity. The protective sheet 46 is provided so as to fit the entire width of the flexible substrate 32 (33) (see FIG. 3). Although the protective sheet 46 can be formed to be considerably thin, it is shown in each figure to be appropriately thick so that it can be easily identified.

Next, the rotation operation and the action effect between the housings 12 and 14 in the electronic device 10 of the present embodiment will be described.

In the 0-degree posture shown in FIG. 4A, the electronic devices 10 are stacked with each other in a state where the front surface 12a of the first housing 12 faces the upper surface 14a of the second housing 14. In this state, the flexible substrate 32 (33) is pulled backward by the second opening 34ab of the hinge mounting portion 34 arranged downward, and the S-shaped portion 36 is arranged along the corrugated plate 14e. Reference numeral C in FIGS. 4A to 4C indicates a center of rotation between the housings 12 and 14 by the hinge 16. Further, reference numeral 43 in FIGS. 4A to 4C is a rubber leg attached to the lower surface 14b of the second housing 14.

In the 0 degree posture, the flexible substrate 32 (33) is not visible because the rear side surface is covered with the second half body 42. Further, the second opening 34ab of the substrate hole 34a faces downward and is hardly visible to the user.

In the 0 degree posture, the substrate hole 34a extends in the vertical direction, and the end portion 44b of the first half body 44 may come into contact with the flexible substrate 32 (33). Since the flexible substrate 32 (33) is guided upward from the second opening 34ab to the folded-back portion 36a by the corrugated plate 14e, the flexible substrate 32 (33) is the end portion 44b of the first half body 44. It can be pressed so as to be convex downward. In particular, since the first half body 44 has a function as a cover for covering the flexible substrate 32 (33), it has a certain downward length, and depending on the length, the end portion 44b makes the flexible substrate 32 (33) slightly stronger. It can also be pressed.

However, since the flexible substrate 32 (33) in the electronic device 10 is provided with the protective sheet 46 on the side facing the first half body 44 in the region passing through the second opening 34ab, the end portion 44b The flexible substrate 32 (33) is protected without being in direct contact with the flexible substrate 32 (33).

If the protective sheet 46 is not provided, the flexible substrate 32 (33) is pressed against the end portion 44b, so that the degree of bending becomes considerably steep and large as shown by the virtual line in FIG. 4A. Get stressed. However, since the flexible substrate 32 (33) is provided with the bending elastic urging force in the direction of returning to a flat surface by the protective sheet 46, the degree of bending becomes an appropriate loose angle, and stress can be reduced. Therefore, even if the rotation of the first housing 12 and the second housing 14 is repeated, the life of the flexible substrate 32 (33) is not shortened.

When using the electronic device 10, the first housing 12 is opened and set to an angular posture between, for example, 90 degrees and 130 degrees. When the first housing 12 is opened from the 0-degree posture shown in FIG. 4A, the front-rear position of the second opening 34ab of the board hole 34a of the hinge mounting portion 34 gradually changes from the 0-degree posture shown in FIG. 4A to the 65-degree posture shown in FIG. 4B, for example. It moves forward and the flexible substrate 32 (33) is pushed forward. Therefore, in the flexible substrate 32 (33), the folded-back portion 36a moves forward while the S-shaped portion 36 is deformed in the second housing 14 (see FIG. 4B). As a result, the flexible substrate 32 (33) can flexibly follow the change even when the relative distance between the display 18 and the substrate 30 (31) changes during the rotational operation between the housings 12 and 14. It is possible to prevent problems such as disconnection from occurring.

Further, in the 65-degree posture, the substrate hole 34a is oriented close to horizontal, and the second opening 34ab is a substantially forward opening and is covered with the second housing 14 and is not visible. Further, the lower surface of the flexible substrate 32 (33) is sufficiently covered with the second half body 42 and is not visible. Since the first half body 44 has an appropriate length, the upper surface of the flexible substrate 32 (33) is almost covered and is not visible.

Further, by the time the posture is changed from 0 degree to 65 degree, the end portion 44b of the first half body 44 may be slightly in contact with the flexible substrate 32 (33), but since the protective sheet 46 is provided, the end portion 44b is provided. The portion 44b does not directly slide and wear the flexible substrate 32 (33), and does not reduce the life of the flexible substrate 32 (33).

From the 65-degree posture shown in FIG. 4B to the 130-degree posture shown in FIG. 4C, the flexible substrate 32 (33) is pulled out rearward according to the position change of the second opening 34ab of the substrate hole 34a of the hinge mounting portion 34. This is almost the same as the shape in the 0 degree posture.

Further, in the 130-degree posture, the substrate hole 34a is inclined downward toward the rear, and the second opening 34ab is an obliquely forward-facing opening, but since the first half body 44 has an appropriate length, it is almost the same. Not visible. Further, the end portion 44b of the first half body 44 may be provided with eaves so that the flexible substrate 32 (33) cannot be visually recognized. Furthermore, the lower surface of the flexible substrate 32 (33) is not visible because it is sufficiently covered with the second half body 42. Since the first half body 44 has an appropriate length, the upper surface of the flexible substrate 32 (33) is almost covered and is not visible.

As shown in FIG. 4C, in the 130-degree posture, the convex portion 42a of the second half body 42 directly abuts and bends the flexible substrate 32 (33). However, in this 130-degree posture, the bending angle of the flexible substrate 32 (33) is gentle, and the bending elastic urging force in the direction of returning the protective sheet 46 to a flat surface acts to make the bending angle even gentler. The stress on (33) can be reduced. In the present embodiment, the flexible substrate 32 (33) is formed on the end portions 44b and the convex portions 42a, which are both edges of the second opening portion 34ab, as the first housing 12 and the second housing 14 rotate. Although the protective sheet 46 is abutted and bent, the protective sheet 46 is provided on the surface facing the end portion 44b which is bent at a steeper angle, and can more appropriately protect the flexible substrate 32 (33).

If the flexible substrate 32 (33) bends at a steeper angle in the 130-degree posture than in the 0-degree posture depending on the design conditions, the protective sheet 46 is the second opening 34ab in the flexible substrate 32 (33). It may be provided on the side facing the end portion (that is, the convex portion 42a) of the second half body 42 in the region passing through.

As described above, the flexible substrate 32 (33) in the electronic device 10 is difficult for the user to see because it passes through the substrate hole 34a of the hinge mounting portion 34. In particular, the first half body 44 forming one surface of the substrate hole 34a has an appropriate length and covers the flexible substrate 32 (33) from the 0 degree position to the 130 degree position to be difficult to see. is doing.

The first half body 44 has an appropriate length in order to make the flexible substrate 32 (33) difficult to see, and the end portion 44b thereof may come into contact with the flexible substrate 32 (33) depending on the rotation angle. , It is properly protected by the protective sheet 46 and does not reduce the life. Since the protective sheet 46 applies a bending elastic urging force in the direction of returning to a flat surface, it is possible to prevent the flexible substrate 32 (33) from being excessively bent and reduce stress.

If the protective sheet 46 is provided on the side of the flexible substrate 32 (33) facing the first half body 44, direct contact with the end portion 44b can be avoided, which is preferable. Even when it is provided in the above, the bending elasticity for returning to a flat surface has an effect of preventing excessive bending, and a corresponding effect for stress reduction can be obtained.

Further, in the electronic device 10, the connected portion 30a (31a) of the substrate 30 (31) is provided downward, and the connecting portion 32a (33a) of the flexible substrate 32 (33) is provided upward. As a result, in the second housing 14, the substrate 30 (31) and the like are fixed to the upper cover material 20 side together with the motherboard 26 and the like. Therefore, the internal maintenance of the second housing 14 can be easily performed by removing the lower cover material 21. At this time, in the second housing 14, since the connecting portion 32a (33a) faces upward, the connecting portion 32a (33a) can be pulled from the connected portion 30a (31a) simply by removing the lower cover material 21 and pulling it. Can be easily removed. Therefore, in the electronic device 10, the display 18 can be easily replaced even though the substrate 30 (31) is mounted on the second housing 14.

The present invention is not limited to the above-described embodiment, and it is needless to say that the present invention can be freely changed without departing from the gist of the present invention.
