Description

  This case relates to an electronic device.

  Conventionally, for example, a notebook personal computer (hereinafter abbreviated as “notebook PC”) has two housings, and the two housings are configured to be openable and closable by hinge parts, and can be folded in two. Electronic devices are known. In the case of such an electronic device that can be folded, the cap is placed so that the hinge part does not appear directly on the appearance. The cap is usually fixed to the housing by screwing. In that case, the head of the screw is covered with a patch so that the screw of the screw does not appear on the appearance. In the case of this structure, in addition to the cap itself covering the hinge parts, screws and patches are required, and an additional man-hour for assembling them is required.

  Here, there are known examples in which the cap is slid from the side and placed on the end of the hinge part, and the hinge cover is inserted from the side and stopped by the latch.

  However, when the cap is slid from the side, there is a problem in appearance because the structure of the slide appears outside the device. Further, here, it is not disclosed that the cap is fixed, and if it is fixed by screwing, a problem similar to the conventional case may occur. In addition, an example in which the hinge cover is inserted from the side and stopped by a latch is a configuration of the hinge itself, and does not fit a cap of a hinge component having a structure in which two casings are configured to be openable and closable like a notebook PC.

  The subject of the electronic device of this indication is providing the structure which fixes the cap component which covers a hinge component without an extra component in what is called a two-fold electronic device.

  The electronic device according to the present disclosure includes a first housing, a second housing, a pair of hinge parts, and a pair of cap parts. The pair of hinge parts is a pair of left and right hinge parts that form a rotating shaft extending in the left-right direction and connect the first housing and the second housing so as to be openable and closable. Here, the left end of the left hinge part and the right end of the right hinge part are fixed to the first casing, and the right end of the left hinge part and the left end of the right hinge part are fixed to the second casing. The pair of cap parts are parts that respectively cover the left end of the left hinge part and the right end of the right hinge part.

  Here, each of the pair of cap parts is attached to the first housing by a first operation and a second operation following the first operation. This first operation is an operation in which the cap part is abutted against the first casing from the direction in which the fixing surface of the first casing to which the pair of hinge parts are fixed faces. The second operation is an operation of sliding the cap component along the first housing.

  Here, each of the pair of cap parts further includes a locking claw protruding in the direction along the fixed surface and a locking protrusion protruding toward the fixed surface.

  Further, the first housing has a latch receiving portion and a latch opening provided corresponding to each of the pair of cap components. The locking receiving portion receives the locking claw in the first operation and locks the locking claw so as to prevent the cap component from floating from the first housing in the second operation. The locking opening has a first receiving portion, a second receiving portion, and a narrow width. The first receiving portion is a portion of the locking opening that receives the locking protrusion in the first operation. The second receiving portion is a portion of the locking opening that receives the locking projection by the second operation. Further, the narrow width portion is a portion of the locking opening that is provided between the first receiving portion and the second receiving portion and is narrower than the first receiving portion and the second receiving portion. The narrow width portion acts as a barrier that the locking protrusion can elastically overcome in the second operation.

  According to the electronic device of the present disclosure, the cap part that covers the hinge part is fixed to the first housing without being screwed or the like.

The connector 253 faces the SSD receiving part 252 and has a structure in which a flexible substrate (FPC) 41 (see FIG. 10A) is inserted from the SSD receiving part 262 side. Further, a boss 264 having a screw hole is erected at a corner of the SSD receiving portion 262.

  FIG. 12 is a perspective view showing the SSD and the flexible substrate. FIG. 13 is a perspective view showing the flexible substrate as seen from another angle.

  The SSD 28 has a plate shape as a whole, and a connector 281 is formed on one side surface thereof. The SSD 28 is an information storage device having a large storage capacity similar to a hard disk drive that has been frequently used in the past.

  Further, the flexible substrate 41 has a connector 411 that is combined with the connector 281 of the SSD 28 fixed at one end, and a connector (terminal row) 412 that is combined with the connector 253 on the substrate 25 is formed at the other end. The flexible substrate 411 is an example of a cable component, and the flexible substrate 411 is formed with a large number of wires for connecting the connector 411 at one end and the connector (terminal row) 412 at the other end.

  A reinforcing plate 413 is fixed at a position adjacent to the connector 411 on the flexible substrate 41. A fixing hole 414 is provided in a portion of the reinforcing plate 413 that protrudes to the side. The fixing hole 414 overlaps with the screw hole of the boss 264 provided at the corner of the SSD receiving portion 262 in a state where the SSD 28 assembled with the connector 411 of the flexible substrate 41 is accommodated in the SSD receiving portion 262. Screwed.

  FIG. 14 is a perspective view showing a state in which the SSD is stored in the SSD receiving portion.

  The SSD 28 is placed on the SSD receiving unit 262 by connecting the connector 281 (see FIG. 12) and the connector 411 of the flexible substrate 41. When placing the SSD 28 in the SSD receiving portion 262, the SSD 28 is in a posture in which the connector 281 of the SSD 28 faces the side wall 21a of the main body side housing 21, that is, when the connector 281 side is the front, the connector 253 on the board 25 is provided. It is placed on the SSD receiving part 262 in a posture with its back facing.

  The flexible substrate 41 is bent upward in FIG. 14 (on the bottom side of the notebook PC 10) at one end where the connector 411 and the reinforcing plate 413 are disposed, and via the path overlapping the SSD 28, the connector (terminal row) 412 at the other end. Reaches the connector 253 on the substrate 25.

  FIG. 15 is a perspective view showing a state in which the flexible substrate is connected to the connector on the substrate. FIG. 16 is a perspective view showing a state in which the flexible substrate is connected to the connector on the substrate.

  When connecting the connector (terminal row) 412 of the flexible substrate 41 and the connector 253 of the substrate 25, the lid 253a of the connector 253 is opened as shown in FIG. 15, and the connector (terminal row) 412 of the flexible substrate 41 is inserted. Thereafter, the cover 253a of the connector 253 is closed, and thereby the circuit on the board 25 and the SSD 28 are electrically connected.

  Here, as described above, the battery pack 24 (see FIGS. 6 and 10) is placed thereon. At that time, the flexible substrate 41 is pushed toward the SSD 28 by the battery pack 24. When the flexible substrate 41 is pushed by the battery pack 24, the SSD 28 is prevented from being lifted from the SSD receiving portion 262, and the SSD 28 is stably held in the SSD receiving portion 262. The outer surface of the battery pack 24 forms the bottom surface of the main body device 20. When the notebook PC 10 is placed on a desk, the bottom surface may be subjected to various impacts. Here, since the flexible substrate 41 is interposed between the SSD 28 and the SSD 28, the flexible substrate 41 serves as a cushion. For this reason, even if an impact is applied to the bottom surface, the impact is not easily transmitted to the SSD 28, and the SSD 28 is protected. Further, the SSD 28 is accommodated in an area adjacent to the side wall 21a of the main body side casing 21 with the connector 281 facing the lateral wall 21a, and is coupled to the connector 411 of the flexible substrate 41 in the narrow area. . With such an arrangement, the flexible board 41 is pushed by the battery pack 24, so that the connectors 281 and 411 are prevented from being disconnected. For this reason, the SSD 28 is fixed to the SSD receiving portion 262 only by fixing a portion of the flexible board 41 adjacent to the portion connected to the connector 281 of the SSD 28 (the hole 414 of the reinforcing plate 413 shown in FIG. 12). It is stably held within.

  Here, the SSD 28 is exemplified, but even electronic components other than SSD such as a compact flash (registered trademark of SanDisk Corporation) can be stably held by the above structure.

(Cooling structure)
FIG. 17 is a perspective view of the battery pack as viewed from the first surface side. In FIG. 17, the internal structure is shown when the cover on the first surface side is seen through.

  In the battery pack 24, two battery cells 243 arranged side by side are arranged in a cover member 240 that covers the entire battery pack 24, and no battery cell 243 is arranged in the center between the two battery cells 243. An area exists. FIG. 17 is a perspective view of a portion on the first surface side facing the inside of the main body device 20 in the cover member 240 covering the whole. The battery cell 243 has a charge / discharge terminal on one side surface. These two battery cells 243 are arranged in such a posture that the side surfaces on which the terminals are formed are oriented in the direction of each other. Between the gaps between the two battery cells 243, wiring (here, the flexible substrate 244) for charging and discharging the battery cells 243 is disposed. The battery pack 24 is also provided with a control board 245 on which a control circuit for controlling charging / discharging of the battery cells is mounted. The flexible board 244 includes the terminals of the two battery cells 243 and the control board. H.245 is connected. Further, the control board 245 and the connector 242 are connected by another flexible board 246, and are responsible for power transfer and control signal transfer with the outside.

  The flexible substrate 244 that extends between the two battery cells 243 is thinner than the thickness of the battery cells 243. Therefore, by using this region, a recess 241 (see FIGS. 6 and 10) is formed in the cover member that covers the first surface (the surface on the inside of the main body device), so that the air in the main body device can flow well. It contributes.

  That is, the first surface of the battery pack 24 has a slight gap between the first surface of the battery pack 24 and the chassis 26 so as to face the chassis 26 (see, for example, FIGS. 6 and 10) that supports the substrate 25. Is placed. A recess 241 is formed so as to partially widen the gap, and the recess 241 extends to a position where a part on the back side overlaps the fan 27 (see, for example, FIGS. 6 and 10). A good air flow is secured by the recess 241. However, in this embodiment, since the flexible substrate 246 connecting the control substrate 245 and the connector 242 crosses the gap between the two battery cells 243, the recess 241 on the first surface of the battery pack 24 is also It is divided on the way. Even if it is divided in this way, the air flow becomes good due to the presence of the recess 241 and the heat radiation efficiency is improved.

  As described above, the second surface (the back surface in FIG. 17) of the battery pack 24 forms the bottom surface of the main body device.

  FIG. 18 is a perspective view of a modified battery pack as viewed from the first surface side.

  In FIG. 18, the same elements as those of the battery pack of FIG. 17 are denoted by the same reference numerals as those shown in FIG. 17, and only differences will be described.

  In the battery pack 24A of FIG. 18, the flexible board 246A connects the control board 245 and the connector 242 through a path that does not straddle the gap between the two battery cells 243. For this reason, the hollow part extended in one without being parted can be formed in the 1st surface of this battery pack 24A. In this case, the flow of air inside the main unit is further improved, and higher cooling efficiency is expected.

  FIG. 19 is a perspective view of the back end surface of the main body of the notebook PC when viewed from the inside in the open state (the side on which the front surface of the display device appears).

  The display device 30 is pivotally supported with respect to the main body device 20 so as to be freely opened and closed. An exhaust port 235 (see FIGS. 4 and 5) is formed at the center upper portion of the end surface on the back side of the main unit 20.

  In the closed state in which the display device 30 is closed on the main body device 20, the display device 30 opens the exhaust port 235 rearward as shown in FIG. On the other hand, in the display device 30, when the display device 30 is opened from the main body device 20, the lower front portion of the housing 31 of the LCD unit 30 is separated from the exhaust port 235 and faces the exhaust port 235.

  20 and 21 are cross-sectional views in the depth direction of the notebook PC in the closed state and the open state, respectively, and are diagrams schematically showing the air flow in the main body device.

  When the notebook PC 10 is in the closed state, as indicated by an arrow in FIG. 20, the air in the main unit 20 flows between the chassis 26 and the battery pack 24 and is sucked into the fan 27 and exhausted from the exhaust port 235. The Here, the flow of air in the region sandwiched between the chassis 26 and the battery pack 24 is shown, but the air between the chassis 26 and the substrate 25 and other regions also has various airflows between components. The air flows into the fan 27 from the gap and is exhausted from the exhaust port 235 by the fan 27.

  The notebook PC 10 can also be used as a music player. When the notebook PC 10 is used as a music player or when a screen display is not required, the notebook PC 10 can be processed in a closed state. Even in the processing in such a closed state, the fan 27 operates and an air flow as shown in FIG. 20 is generated.

  Further, as indicated by an arrow in FIG. 21, when the notebook PC 10 is in the open state, the air flow inside the main unit 20 is the same as in the closed state, but the air exhausted from the exhaust port 235. Flows along the front surface of the display device 30. When the notebook PC 10 is a small notebook PC, it can be used with one hand or both hands without being placed on a desk. At that time, if the exhaust air blown out from the exhaust port 235 is blown to another person nearby, there is a risk of inconvenience. Here, in the open state, which is the main usage mode of the notebook PC 10, the configuration is such that the air exhausted from the exhaust port 235 travels along the front surface of the display device 30, thereby greatly reducing inconvenience to others. .

  On the other hand, in the closed state, the air exhausted from the exhaust port 235 proceeds in the depth direction of the main unit 20 as shown in FIG. However, when the notebook PC 10 is used in a closed state, the notebook PC 10 must be used in a posture in which the exhausted air is not blown to others, for example, when the notebook PC is used in a standing state or on a desk. Many problems do not arise. This notebook PC 10 is used even in the closed state, but in the case of a notebook PC that is used exclusively in the opened state, the orientation of the exhaust port 235 in the closed state is not a problem at all.
