[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a portable electronic device including a main body and a display unit that can be opened and closed with respect to the main body, and a battery for the electronic device.
[0002]
[Prior art]
In recent years, many portable electronic devices have been released, and advanced electronic devices equipped with a CPU (Central Processing Unit) have appeared. A large amount of power is consumed to drive such an electronic device.
Of portable electronic devices, for example, a portable computer includes a main body and a display unit thereof, and the display unit can be opened and closed with respect to the main body via a hinge. A typical example of such a portable computer is a computer called a notebook personal computer.
[0003]
In order to drive the main body and the display unit of this type of portable computer, a battery is mounted. In order to drive the main body and the display unit of such a battery, the battery pack is set outside the main body, for example, and the capacity of the battery pack is large to small. When increasing the capacity of the battery pack, a large number of battery cells (single batteries) are mounted, so the outer shape is large and heavy. In addition, a battery with a small capacity has a relatively small external shape because it has a small number of battery cells.
In a battery pack with a large capacity, since the number of battery cells to be mounted is large, the battery cells are generally arranged in a plurality of rows.
A portable computer having this type of battery pack is disclosed in Japanese Patent Laid-Open No. 8-76898. The disclosed battery pack 2004 is electrically connected to a computer main body 2000 as shown in FIGS.
[0004]
[Problems to be solved by the invention]
However, the battery pack 2004 is integrally formed and attached so that the entire battery pack 2004 rotates with respect to the main body 2004 of the computer. When the entire battery pack 2004 is rotated in the arrow direction Y with respect to the main body 2000 to support the rear end portion of the main body upward such as a desk, and the main body 2000 is inclined by this, a heavy battery pack is used. There is a problem that the entire 2004 has to be rotated with respect to the main body 2000 and the operability is poor.
In the portable computer shown in FIGS. 27 and 28, a battery pack 2004 is attached to the rear end portion of the main body 2000. The battery pack 2004 is located at the rear end of the main body 2000 and the display unit 2003. The entire battery pack 2004 can rotate 90 ° in the arrow direction Y with respect to the main body 2000 and the display unit 2003 as shown in FIG. By rotating in this way, the rear end portion of the main body 2000 can be lifted from the support surface and tilted.
[0005]
However, if such a structure is employed, the entire battery pack 2004 must be electrically and mechanically connected to the rear end side of the main body 2000 and can rotate as shown in FIG. Therefore, the battery pack 2004 must include the rotating electrode 2005 and the rotating connector 2006 on the main body 2000 side. As described above, the structure in which the battery pack 2004 is rotatably and detachably attached to the main body 2000, the special concentric rotating electrode 2005 and the rotating connector 2006 must be provided, and the structure becomes very complicated. In addition, when the battery pack 2004 is repeatedly rotated, there is a possibility that poor electrical connection between the rotating electrode 2005 and the rotating connector 2006 may occur.
Thus, in the conventional structure, a special annular contact structure that supports the battery pack 2004 in a rotatable manner and maintains electrical contact in a rotatable manner is indispensable, the structure is complicated, the number of parts is increased, and the manufacturing is performed. There have been problems such as an increase in cost, occurrence of poor contact due to secular change, and deterioration of durability due to stress concentration when supporting the battery pack 2004 having a relatively large mass.
Therefore, the present invention solves the above problems, and can easily perform an operation of rotating a part of the battery and tilting the main body by supporting the rear end of the main body of the electronic device upward.

The embodiment described below is a preferred specific example of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these forms.
FIG. 1 shows an example of an electronic device having a battery of the present invention, and the electronic device of FIG. 1 is a portable computer 100. The portable computer 100 includes a main body 2, a display unit 3, a keyboard 4, hinges 1 </ b> A and 1 </ b> B surrounded by A and B areas, a battery pack (battery) 200, and the like.
[0027]
The main body 2 has the keyboard 4 and other pointing devices 5 described above, and the display unit 3 can employ, for example, a liquid crystal display (LCD). The display unit 3 is attached to the main body 2 so as to be opened and closed (folded) in the direction of arrow R using hinges 1A and 1B (first opening and closing mechanism and second opening and closing mechanism). Although not shown in FIG. 1, for the main body 2, an external device such as a mouse that is an external pointing means can be set. The main body 2 has a power lamp PL, a battery lamp BL, and a message lamp ML. The battery lamp BL indicates the degree of remaining battery capacity of the battery pack 200.
[0028]
FIG. 2 is a view of the display unit 3 of the electronic device of FIG. 1 folded from the main body 2 around the central axis CLC and viewed from the arrow SD. In FIG. 2, a power switch 40 and other switches 41 and 42 are disposed on the side surface 2S of the main body 2. The side surface 2S is provided with a slot 43 for inserting an electronic card (PC card).
[0029]
A battery pack (battery) 200 is disposed between the hinges 1A and 1B in FIG. As shown in FIGS. 2, 3 to 6, the battery pack 200 includes a substantially cylindrical long battery portion (corresponding to a second battery portion) 220 and a substantially cylindrical short battery portion (corresponding to a first battery portion). 210). The short battery portion 210 is fixed to the rear end portion 2F of the main body 2 so as to be mechanically detachable between the hinges 1A and 1B and electrically detachable.
[0030]
As shown in FIG. 2, the thickness of the case (housing) of the main body 2 and the case (housing) of the display unit 3 are as follows. The thickness t1 is 1.2 mm, the thickness t2 is 1.0 mm, the thickness t3 is 1.0 mm, and the thickness t4 is 1.2 mm.
The total thickness M of the main body 2 and the display unit 3 is substantially the same as the diameter K of the long battery unit 220 and the short battery unit 210.
The short battery unit 210 is detachably set between the hinges 1A and 1B, and the diameters of the hinges 1A and 1B and the short battery unit 210 can be made substantially the same. It can be as large as possible within the range of M.
[0031]
As shown in FIG. 3, the long battery row 220 is rotatably supported using a hinge mechanism 240 with respect to the short battery row 210. That is, the protrusion 221 of the long battery unit 220 is fitted into the recess 211 of the short battery unit 210, and for example, the protrusion 221 is rotatably connected to the recess 211 by the pin 222.
A plurality of secondary batteries are arranged in the long battery unit 210, and similarly, a plurality of secondary batteries are arranged in the short battery unit 220. As the secondary battery, for example, a lithium ion secondary battery can be used. Although the short battery unit 210 is disposed between the hinges 1 </ b> A and 1 </ b> B, the length of the long battery unit 220 can be substantially the same as the width W of the main body 2 and the display unit 3. Moreover, the diameter of the short battery row 210 and the diameter of the long battery row 220 can be made substantially the same. This makes it possible to increase the battery capacity as much as possible.
[0032]
Next, the mechanism part which the short battery row | line | column 210 can detachably fix to hinge 1A, 1B is demonstrated with reference to FIGS. As shown in FIGS. 4 and 5, the short battery row 210 is fixed with its center axis CLC aligned with the center axis corresponding to the rotation center of the hinges 1A and 1B. The fixing mechanism is as shown in FIG. The other battery row 210 of the battery pack 200 has a case 213 made of plastic, for example, and grooves 203 are formed at both ends of the case 213. An abutting surface 209 is provided on the end surface of the case 213 along the axial direction, and two attaching portions 202 and 202 and an electric connection terminal 204 are provided on the abutting surface 209 so as to protrude.
[0033]
On the other hand, the rear end portion 2F of the main body 2 is provided with concave portions 302, 302 and a concave electrical connection terminal 304. The attachment portion 202 can be fitted in correspondence with the concave portion 302, and the electrical connection terminal 204 can be fitted into and electrically connected to the concave electrical connection terminal 304. Moreover, the grooves 203 and 203 can be fitted into the protrusions 303 and 303 provided on the hinges 1A and 1B. In this way, the other battery row 210 can be reliably fixed to the rear end portion 2F of the main body 2. Thus, the battery row 220 and the other battery row 210 of the battery pack 200 are securely and electrically attached to and detached from the main body 2 side using the grooves 203 and 203, the mounting portions 202 and 202, and the electrical connection terminals 204. Can be fixed as possible. With the battery pack 200 attached to the main body in this way, drive power is supplied from the battery pack 200 to the main body 2 via the electrical connection terminal 204.
That is, the attachment portions 202 and 202 are mechanically fitted in the recess 302 of the main body 2, and the electrical connection terminal 204 is electrically connected to the electrical connection terminal 304 of the main body 2.
Moreover, since the battery pack 200 can be guided by the grooves 203 and 203 and the projecting portions 303 and 303, the electrical connection terminals 204 and 304 of the battery pack 200 can be guided to the electrical connection terminals 304 due to stress when the electrical connection terminals 204 are attached to or removed from the electrical connection terminals 304. Damage can be prevented.
[0034]
Since the battery pack 200 is detachably provided between the hinges 1 </ b> A and 1 </ b> B, which are a plurality of opening / closing mechanisms, the display unit 3 can be opened by 180 ° or more with respect to the main body 2. For example, when the main body 2 is placed on the user's lap and the display unit 3 is opened 180 degrees or more in the R direction of FIG. For example, as shown in FIG. Accordingly, the user can operate the keyboard of the main body 2 while viewing the display unit 3 in a state where the display unit 3 is opened in the R direction by 180 degrees or more with respect to the main body 21, and the operability can be improved.
Even if the display unit 3 is rotated 180 degrees or more in the R direction with respect to the main body 2, the display unit 3 does not contact the long battery unit 220, and the display unit 3, the battery pack 200, and the main body 2 can be prevented from being damaged, the battery itself and the display unit can be prevented from being damaged.
[0035]
FIG. 8 shows the shape of the battery pack 200 of FIG. 7 in more detail. The short battery unit 210 includes, for example, two battery bodies 210A, and the long battery unit 220 includes, for example, three battery bodies although not shown.
FIG. 13 shows a protrusion 221 and the like in the vicinity of the battery body 210A. The protrusions 221 connect the battery units 210 and 220, and a circuit board 299 is disposed in the case of the battery unit 210.
[0036]
As shown in FIGS. 9 and 10, the long battery unit 220 includes anti-slip 235 and 235. The slip stoppers 235 and 235 are made of, for example, rubber having a high frictional resistance. The reason why the slip stoppers 235 and 235 are provided in this manner is to reliably exhibit the tilt support function of the main body as shown in FIGS. 14, 15, and 16.
[0037]
14 and 16A, for example, when the display unit 3 is folded and stored in the main body 2 or carried, the long battery unit 220 and the short battery unit 210 are connected to the main unit 2 and the display unit 3. Are arranged in the direction of arrow N along the front-rear direction.
On the other hand, as shown in FIGS. 15 and 16B, when the computer 100 is actually placed on a desk or the like and used, the display unit 3 is opened from the main body 2 in the direction of arrow R, and The user uses the long battery unit 220 by rotating it by about 90 degrees with respect to the short battery unit 210.
Thereby, only the long battery part 220 moves below the rear end part 2F of the main body 2, and therefore the rear end part 2F of the main body 2 is lifted above the support surface SP by a height corresponding to the predetermined height K. Can do. In this way, the operability of the keyboard 4 of the main body 2 is improved and the user can easily use the computer 100. At this time, since the anti-slip 235 is in contact with the support surface SP, the computer 100 itself does not move easily. In this case, it is only necessary to rotate the short battery unit 220, and it is not necessary to rotate the entire battery pack 200 with respect to the main body 2, so that the operation is easy.
[0038]
FIG. 17 shows one connecting portion of the battery units 210 and 220 and the rotation prevention mechanism 450. In the vicinity of the protrusion 221 of the battery unit 220, an unlock slider 400 is disposed in the recess 401 of the case of the battery unit 210. The unlock slider 400 can forcibly move the stopper member 402 in the direction of arrow F.
The stopper member 402 is pushed in a direction opposite to the arrow F direction by a biasing means 404 such as a spring against the fixed portion 210R of the battery unit 210.
Thus, the stopper member 402 protrudes from the case hole 405 of the battery row 201 to the protrusion 221 side. The stopper member 402, the unlock slider 400, the urging means 404, and the like constitute a rotation prevention mechanism 450 that prevents the long battery unit 220 from rotating in the S direction with respect to the short battery unit 210.
[0039]
The rotation prevention mechanism 450 further has a hole 451 as shown in FIGS. The hole 451 is formed in the protrusion 221. The stopper member 402 is fitted into the hole 451 at a position where the long battery portion 220 is rotated 90 degrees in the S direction with respect to the short battery portion 210 (see FIG. 15). With the stopper member 402 thus fitted in the hole 451, the user can move the unlocking slider 400 in the F direction so that the stopper member 402 can be escaped from the hole 451.
[0040]
Next, an operation example of the rotation prevention mechanism 450 will be described with reference to FIGS.
As shown in FIG. 14 described above, when the long battery unit 220 is parallel to the short battery unit 210, the main body 2 and the battery units 210 and 220 are placed side by side with respect to the support surface SP. . As shown in FIGS. 14 and 15, when the rear end portion of the main body 2 is lifted and supported from the support surface SP, the long battery portion 220 rotates 90 degrees with respect to the short battery portion 210 as described above. .
[0041]
19 and 17 show the positional relationship between the battery units 210 and 220 shown in FIG. In this case, the stopper member 402 is in contact with the front surface of the protrusion 221 provided on the short battery unit 220.
When the user wants to lift and support the rear end 2F of the main body 2 as shown in FIGS. 14 to 15, the user slightly lifts the long battery part 220 in the S direction as shown in FIGS. It rotates one by one. At this time, since the protrusion 221 forcibly pushes the stopper member 402 of the rotation prevention mechanism 450 in the F direction, the stopper member 402 is retracted from the protrusion 221 and immersed in the hole 405.
[0042]
Here, since the stopper member 402 is formed in a triangular shape as shown in FIG. 17, when the long battery unit 220 is rotated, the stopper member 402 is pushed in the F direction by the protrusion 221.
When the stopper member 402 is pushed into the hole 405 and the long battery unit 220 rotates in the S direction with respect to the short battery unit 210, the long battery unit 220 is replaced with the short battery unit 210 as shown in FIG. It will be in the state rotated about 90 degree | times with respect to this. This situation is shown in FIGS.
In such a state of being rotated approximately 90 degrees, the stopper member 402 is fitted into the hole 451 of the protrusion 221 provided in the long battery unit 220 by the force of the biasing means 404. As a result, when the long battery unit 220 shown in FIG. 15 is erected, the lock function automatically works so as not to return to the original direction due to the action of the stopper member 402 of FIGS. 21 and 22. Accordingly, the rear end portion 2F of the main body 2 can be reliably tilted and held with respect to the support surface SP, and the battery row 220 returns to the original state during operation of the computer, and the rear end portion 2F suddenly drops. To avoid trouble.
[0043]
When the user returns the main body 2 from the state shown in FIG. 15 to the state shown in FIG. 14 again, the user slides the unlock slider 400 shown in FIGS. 402 is forced out of the hole 451. Thereby, the user can return to the state of FIG. 14 if the long battery part 220 is rotated about 90 degrees in the direction opposite to the S direction with respect to the short battery part 210.
[0044]
Next, FIGS. 4, 5 and 23 show a central processing unit (CPU) 35 as a heat generation source in the electronic apparatus of the present invention, a case (housing) 2B of the main body 2, one hinge 1B and the display unit 3. The case (housing) 3A is shown. In FIG. 4, heat generated by driving the central processing unit 35, which is a heat generation source, is transferred from the substrate 36 on which the central processing unit 35 is mounted to the case 3A side of the display unit 3 via the hinge 1B and the like. An example of the process of heat dissipation or dispersion is shown.
Specifically, a substrate 36 is disposed in the case 2B of FIG. 23, and a central processing unit 35 is mounted on the substrate 36. On the other hand, the case (housing) 3A and the case (housing) 2B are mechanically connected to each other by hinges 1A and 1B (the hinge 1A is not shown) so as to be openable and closable. Thermal conduction is intended from the 2B and substrate 36 side to the case 3A side.
[0045]
In the example of FIGS. 4 and 5, since the central processing unit 35 is disposed substantially at the center of the substrate 36, there is a space between the hinge 1 </ b> B. Therefore, on the central processing unit 35 side, a heat receiving plate 37 that receives heat from the central processing unit 35, a heat pipe 38, and a connector 39 are arranged between the hinge 1B and the central processing unit 35. The heat receiving plate 37 is disposed above the central processing unit 35 with a predetermined interval, for example. The heat receiving plate 37 and the connector 39 are connected by a heat pipe 38. The heat pipe 38 and the heat receiving plate 37 can be made of a metal having good thermal conductivity, such as copper. The size of the heat receiving plate 37 is set larger than the size of the central processing unit 35.
[0046]
The connector 39 is also made of a material having good thermal conductivity, for example, copper, and can be fixed to the case 2B side of the main body 2 by using screws 31 to the fixing piece 11 side of the hinge 1B.
On the other hand, the movable piece 17 side of the hinge 1B is fixed to the inside of the case 3A by a screw 32.
As will be described later, the hinge 1B has a function of efficiently conducting heat from the fixed piece 11 side to the movable piece 17 side.
[0047]
Here, with reference to FIG. 23, it will be described how the heat generated by the central processing unit 35 is transmitted to the case 3A side.
When the central processing unit 35 is driven to generate heat, the heat receiving plate 37 receives the heat of the central processing unit 35 along the arrow AL1. The heat receiving plate 37 transmits the received heat along the arrows AL2, AL3 and AL4 to the fixed piece 11 side of the hinge 1B via the heat pipe 38 and the connector 39.
As a result, heat is transferred along the AL5 from the fixed piece 11 side of the hinge 1B to the movable piece 17 side, and then this heat is transferred to the case 3A side as indicated by an arrow AL6. As a result, the transmitted heat is radiated or diffused to the case 3A along the arrow AL7.
[0048]
As described above, heat is transferred from the main body 2 side having a relatively large heat generation rate to the display unit 3 side having a relatively small heat generation amount, so that heat buildup in the main body 2 in the computer 100 which is the electronic device 1 can be prevented. Therefore, it is possible to easily diffuse or disperse heat to the display unit 3 side. In this way, heat can be easily dispersed by using a hinge without providing a special heat sink or conductive fan.
[0049]
In the example of FIG. 23, heat conduction is performed using one hinge 1B, but it is needless to say that heat conduction may be performed using both hinges 1A and 1B.

The strength holding portion 17a is a portion that holds mechanical strength, and the heat conducting portion 13 is a portion that conducts heat. In order to maintain the strength when the display unit is opened and closed and the strength of the strength holding unit 17a, it is preferable to employ a mechanically strong material, for example, stainless steel (SUS) which is an iron-based material.
The heat conduction part 13 can employ a material having good heat conduction, such as copper or aluminum. The strength holding portion 17a is formed in a substantially L shape, but the heat conducting portion 13 is also formed in a substantially L shape. However, the portion 13a of the heat conducting portion 13 is in close contact with the strength holding portion 17a, and the rising portion 13b of the heat conducting portion 13 is separated from the rising portion 17b of the strength holding portion 17a. Used.
[0054]
In FIG. 26, the strength holding part 17a and the heat conducting part 13 of the movable piece 17 are shown three-dimensionally. Circular holes 17c and 13c are formed in the rising part 17b of the strength holding part 17a and the rising part 13b of the heat conducting part 13, respectively. However, the diameter of the hole 17c is set smaller than the diameter of the hole 13c.

The shaft 15 is made of, for example, iron in order to maintain mechanical strength, and has a protruding portion 15b opposite to the protruding portion 15a with respect to the main body 15c of the shaft 15. The protruding portion 15a passes through the hole 14a of the spring washer 14, passes through the hole 13c of the heat conducting portion 13, the hole 12c of the heat conducting portion 12, and the hole 11c of the strength holding portion 11a. The shape of the projecting portion 15a has end faces 15e and 15e that are securely fitted into the hole 12c of the heat conducting portion 12 and the hole 11c of the strength holding portion 11a so as not to move. Therefore, the protruding portion 15a of the shaft 15 can be securely fixed so as not to be detached by fitting into the hole 12c of the heat conducting portion 12a and the hole 11c of the strength holding portion 11a.
[0057]
The spring washer 14 is a spring member for firmly adhering the heat conducting part 12 of the fixed piece 11 and the heat conducting part 13 of the movable piece 17 and is made of a metal such as iron, for example.
The washer 16 is a washer disposed between the shaft 15 and the strength holding portion 17 a of the movable piece 17. The hole 16c of the washer 16 is a rectangular hole into which the protruding portion 15b of the shaft 15 is fitted. The protruding portion 15b of the shaft 15 also has flat end surfaces 15f and 15f. The protruding portion 15b passes through the hole 17c of the strength holding portion 17a, and the protruding portion 15b passes through the hole 18c of the washer 18 and the hole 19c of the spring washer 19 and securely fits into the hole 20c of the stopper 20. ing. That is, in the hole 20c of the stopper 20, it can fix reliably so that the protrusion part 15b of the shaft 15 may not remove | deviate.
[0058]
In this way, the fixed piece 11 and the movable piece 17 use the meshing connection of the protruding portion 15a of the shaft 15 and the hole 11c of the strength holding portion 11a, and the meshing connection of the protruding portion 15b of the shaft 15 and the hole 20c of the stopper 20. The movable piece 17 can be rotated in the R direction of FIG. 16 with respect to the fixed piece 11 by using this shaft 15.
[0059]
The shaft 15, washers 16, 18, spring washers 14, 19, stopper 20, and the like can be made of a mechanically strong material, for example, an iron-based material. The heat conducting portion 12 of the fixed piece 11 is positioned on the attachment surface side (the side in contact with the main body) of the main body 2 of the computer 100 in FIG. 1 and is fixed using screws 32 as shown in FIGS. Can do. On the other hand, the heat conducting portion 13a of the movable piece 17 is located on the attachment surface side (attachment surface to the display portion) of the display unit 3 of the computer 100 in FIG.
[0060]
As shown in FIGS. 24 and 25, when the hinge 1A or 1B is assembled, the rising portion 12b of the heat conducting portion 12 of the fixed piece 11 and the rising portion 13b of the heat conducting portion 13 of the movable piece 17 are in close contact with each other. In addition, since the spring washer 14 brings these rising portions 12b and 13b into close contact with each other by a spring pressing force, the thermal resistance of the contact portions at the rising portions 12b and 13b of these heat conducting portions 12 and 13 can be achieved. As small as possible.
[0061]
Such a hinge 1A or 1B maintains mechanical strength and has a heat conduction and heat dissipation function. For example, in the main body 2 and the display unit 3 of the computer 100, the heat conduction that goes to and from each other is improved and the amount of heat is improved. The heat can be easily transferred from the side having a large amount of heat, for example, from the main body 2 side to the side having a small amount of heat, for example, the display unit 3.
By improving the thermal conductivity as described above, it is possible to improve the conduction of heat from the main body 2 that generates a large amount of heat to the display unit 3 that generates a small amount of heat, and a place for heat dissipation can be secured. This heat dissipating means can be newly provided for the heat conducting section 12 and the heat conducting section 13, and the heat dissipating efficiency can be increased.
[0062]
For example, if the case 2A and 3A of the main body 2 and the display unit 3 in FIG. 23 are made of a light metal such as magnesium, the exterior can be used as a heat sink as it is. The cases 2A and 3A used as the heat sink are By thermally connecting to the conduction part 12 and the heat conduction part 13, the heat dissipation effect can be further improved.
In general, a material having good thermal conductivity has a physical characteristic that electric resistance is low. Therefore, the fixed piece 11 and the movable piece 17 side of the hinges 1A and 1B are connected to the lower pieces of electricity through the hinges 1A and 1B. It can couple | bond through a resistance part.
[0063]
For example, if the entire case 3A of FIG. 23 is made of a metal having good thermal conductivity, the heat can be radiated to the outside by the entire case 3A. As a material for forming the case 3A in this case, a magnesium alloy can be preferably used. As the magnesium alloy, a magnesium metal material such as AZ91D can be used. The thermal conductivity of this magnesium is 157 W / mK. For example, 1.2 mm can be adopted as the plate thickness of the case 3A. The length / width / thickness dimension of the case 3A can be set to, for example, 259 mm × 208.6 mm × 23.9 mm. As the central processing unit to be mounted, for example, a product such as a Pentium processor 133 MHz manufactured by Intel Corporation can be adopted. In this case, the heat generation amount per unit time is about 6 W.
