  4 and 5 are views of a foldable mobile phone, which is an example of a conventional battery storage device, as viewed from the back. FIG. 4 shows a state in which a recess is opened by removing a battery lid provided on the back of the foldable mobile phone. FIG. 5 is a perspective view showing a state where the battery lid is attached and the recess is closed. 4 and 5, the folding cellular phone includes a first casing 1 having a substantially flat back surface A, and a second casing that is rotatably connected to one end of the first casing 1 by a connecting portion 3 (hinge). 2. Although not shown, an operation portion (operation key) and a transmission portion are provided on the facing surface of the first housing 1 when the first housing 1 and the second housing 2 are folded. Is provided with a receiver and a display. When the foldable mobile phone is not used, it is placed on the installation surface so that the back surface A of the first housing 1 faces downward with the housings 1 and 2 folded as shown in FIG. It has become.

  By the way, as shown in FIG. 4, a rectangular battery housing recess 5 for housing the battery 4 is formed on the back surface A of the first housing 1, and the battery 4 (mobile phone) is formed in the battery housing recess 5. In general, a secondary battery) is stored. The first casing 1 is provided with a battery lid 6 that can be attached to and detached from the battery housing recess 5 by a slide. The battery housing recess 5 and the battery lid 6 constitute a battery housing device. Yes.

  An example of a configuration for detaching the battery cover 6 from the battery housing recess 5 by sliding is shown in FIG. That is, the front end portion 5a of the battery accommodating recess 5 on the connecting portion 3 side is formed with a locking opening 8 and two lifting prevention holes 9 in the width direction, and the rear end of the battery accommodating recess 5 Lifting prevention holes 10 are formed at two places in the width direction near the portion 5b. A hook 11 is formed at the front end of the battery lid 6 so as to be deformed when the battery lid 6 is pushed forward and fitted into the locking opening 8 to be locked in the locking opening 8. At the same time when the hook 11 is locked in the locking opening 8, there are provided four tongues 12 that fit into the front and rear lifting prevention holes 9, 10.

  As shown in FIG. 5, the battery cover 6 has a substantially U-shaped cross section that extends from the back surface A of the first housing 1 to a part of the side surface. The boundary line 13 between the first casing 1 and the battery lid 6 appeared.

  However, the mobile phone shown in FIGS. 4 and 5 has a shape in which the battery cover 6 wraps around from the back surface A of the first housing 1 to a part of the side surface, and the first housing 1 is provided on the side surface of the first housing 1. 1 and the battery lid 6 appeared, the boundary line 13 was conspicuous and the design aesthetics were impaired. Therefore, the conventional mobile phone is required to make the clearance at the boundary line 13 as small as possible. However, reducing the clearance at the boundary line 13 has a problem that it is necessary to increase the precision of the production unnecessarily and the production becomes difficult. Furthermore, if the clearance is small, there is a problem that the mating portion is rubbed when the battery cover 6 is slid and detached, and the first casing 1 is damaged and the paint is peeled off or the battery cover 6 is scraped off. It was.

  In recent years, mobile phones with various designs have been proposed, and the battery lid 6 may have to be tapered depending on the design. However, even when the battery lid 6 is tapered like this, if the clearance at the boundary line 13 appearing on the side surface of the first casing 1 is reduced, the battery lid 6 is caught by the first casing 1 when the battery lid 6 is detached. The problem that the first casing 1 is damaged due to the rubbing of the part and the paint peels off or the battery cover 6 is scraped similarly occurs.

  On the other hand, in the above-mentioned Patent Document 1, since the battery lid is attached to and removed from the battery storage chamber in the vertical direction by providing a stopper that can be moved in and out by a spring instead of sliding and removing the battery lid. The problem of rubbing the casing and the battery lid sometimes can be reduced.

  However, in recent years, there has been a demand for downsizing and thinning of electronic devices such as mobile phones. As described above, a stopper that protrudes and retracts toward the battery storage chamber by a spring is provided inside the housing of such a thin mobile phone. Is difficult.

  The present invention has been made in view of the above circumstances, and can prevent damage due to rubbing between the casing and the battery lid when the battery lid is attached and detached, and the boundary line between the casing and the battery lid is disposed on the rear surface of the casing. It is an object of the present invention to provide a battery storage device with enhanced design aesthetics.

The invention according to claim 1 is a housing in which a tapered recess having a smaller width on the other end side than the width on the one end side is formed on the back surface ;
And a plate-shaped battery lid of detachably tapered shape configured in the recess of the housing by a slide,
A notch is formed at the boundary between the inner surface and the side surface of the battery lid ,
A battery storage device, wherein when the battery cover is removed from the recess by sliding from one end side of the housing toward the other end side, the cutout portion rises up a side surface of the recess ; It is related to.

According to a second aspect of the present invention, in the battery storage device according to the first aspect, the notch portion is formed by being inclined and notched from the inner surface to the side surface of the battery lid. It is concerned.

The invention according to claim 3 relates to the battery storage device according to claim 1, wherein a space is formed between the battery lid and the recess by the notch. is there.
According to a fourth aspect of the present invention, there is provided a battery according to any one of the first to third aspects, wherein a gap is provided between a side surface of the battery lid and a side surface of the concave portion of the housing. This relates to a storage device.

  In the invention according to claim 1, since the taper-shaped plate-shaped battery lid is detachably provided in the recess of the housing, and the notch is provided at the boundary between the inner surface and the side surface of the battery lid. In addition, by acting so that the notch rises to the side surface of the concave portion, it is possible to reduce damage to the casing due to rubbing between the concave portion and the battery lid. In particular, even when at least the width of the battery lid has a tapered shape toward the tip, when the battery lid is removed from the recess, the side surface of the battery lid acts so as to rise up to the side surface of the recess and scratches are caused by rubbing each other. Can be effectively reduced.

  In the invention which concerns on Claim 2, since the battery cover was arrange | positioned in the back surface of a housing, the boundary line of a battery cover and a housing does not appear outside at the time of normal use, and design aesthetics are improved.

  Also, when removing the tapered battery lid from the housing, the gap between the side surfaces of the recesses is tapered, and the housing and the battery lid are likely to rub, but the boundary between the inner surface and the side surface of the battery lid Since the notch is provided on the side, the notch can act so as to rise up to the side surface of the recess, thereby reducing damage caused by rubbing between the recess and the battery lid.

  In the invention according to claim 3, since the gap is provided between the side surface of the battery lid and the side surface of the concave portion of the casing, the battery lid can be attached and detached more smoothly by the gap, thereby further reducing the problem due to rubbing. In addition, it is easy to manufacture because the boundary line does not require high precision.

  At this time, because the boundary line between the side surface of the battery lid and the side surface of the concave portion of the housing is located in the back surface of the battery storage device, the boundary line located on the back surface of the battery storage device does not appear outside during normal use, Even if a relatively large gap is provided, the aesthetic appearance of the design is not impaired, so that the boundary line is not required to have high accuracy and can be manufactured easily.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  1 to 3 show a foldable mobile phone which is an example of a battery storage device of the present invention. FIG. 1 shows a case where a battery cover provided on the back of the foldable mobile phone is removed to open a recess for storing a battery. 2 is a perspective view showing a state in which the battery lid of FIG. 1 is attached and the recess is closed, and FIG. 3 is a view taken in the direction of arrows III-III in FIG. , Those given the same reference numerals as in FIG. 5 represent the same constituent members.

  The mobile phone shown in FIG. 1 and FIG. 2 has a first casing 1 having a battery cover 6 on the back surface A and a second pivotally connected by a connecting portion 3 (hinge) provided at one end of the first casing 1. An opposing surface of the first casing 1 that has a casing 2 and faces the first casing 1 and the second casing 2 when the first casing 1 and the second casing 2 are folded with each other includes an operation unit such as a numeric keypad and a cursor key, and a transmitter. Moreover, a display unit such as a liquid crystal display device or an organic EL (not shown) and a receiver unit are provided on the opposing surface of the second casing 2.

  Each of the first casing 1 and the second casing 2 has a tapered shape in which the width dimension on the other end side is smaller than the width dimension on the one end section on the connecting portion 3 side. The battery lid 6 provided on the back surface 1 (the opposite surface to the opposite surface) A also has a width W2 on the rear end side that is smaller than a width W1 on the front end side corresponding to the connecting portion 3 side. It has a tapered shape toward the side.

  On the back surface A side of the first casing 1 having a tapered shape, a first recess 51 in which the battery cover 6 is accommodated, and a width dimension smaller than the width dimension of the first recess 51 and the first A second battery housing recess 5 for housing a battery formed so as to open in the recess 51 is formed, and the battery lid 6 having a tapered shape is formed in the first recess 51 opened in the back surface A. Is detachably attached by slide. The planar shape of the first recess 51 is formed in a tapered shape that is substantially the same as the planar shape of the battery lid 6. Then, by sliding the battery lid 6, the two tongue portions 12 protruding from the front end of the battery lid 6 are respectively inserted into the lifting prevention holes 9 formed in the front end portion 51 a of the first recess 51, and the battery lid The two tongue portions 12 projecting inward from the rear end of the battery 6 are inserted into the lifting prevention holes 10 formed in the rear end of the first recess 51, and the hook 11 projects from the front end of the battery cover 6. The battery lid 6 is fixed and accommodated in the first recess 51 by being fitted into the locking opening 8 formed in the front end portion 51 a of the first recess 51 and being locked.

  As described above, since the first recess 51 in which the battery lid 6 is accommodated is provided on the back surface A of the first casing 1, the first casing 1 and the battery lid 6 are arranged as shown in FIG. 2. The boundary line 14 does not appear on the side surface of the first housing 1 and can be positioned on the back surface A side. Therefore, the outer shapes of the casings 1 and 2 can be various shapes, for example, a battery lid that can be attached to the casing 1 without being restricted by the design even when it is tapered like the present embodiment. 6 can be provided, and the boundary between the casing main body and the battery lid formed on the side face of the casing 1 that has been difficult in the prior art can be eliminated. Note that the structure for attaching and detaching the battery cover 6 by the slide is not limited to that shown in the present embodiment.

  Further, as shown in FIG. 3, a chamfering is provided at the boundary between the inner surface 6a and the side surface 6b of the battery cover 6 to provide a cutout portion 15 having a tapered surface of about 45 °, for example. In FIG. 3, the notch 15 is a tapered surface, but it may be a curved surface.

  Further, in the conventional mobile phone, it is required to make the clearance at the boundary line 13 between the first casing 1 and the battery lid 6 as small as possible. However, in the present invention, the side surface 6b of the battery lid 6 and the first recess 51 are provided. A required gap S is provided between the side surface 51c of the first and second side surfaces 51c. That is, as shown in FIG. 2, the boundary line 14 between the side surface 6b of the battery cover 6 and the side surface 51c of the first recess 51 is disposed in the back surface A of the mobile phone, so that it is positioned on the back surface A of the mobile phone. The boundary line 14 does not impair the aesthetic appearance, and therefore, the boundary line 14 can be provided with a relatively large gap S of about 0.2 to 1.0 mm, for example. However, when the gap S is less than 0.2 mm, high dimensional accuracy is required for the battery lid 6 and the first recess 51, and when the gap S exceeds 1.0 mm, the gap becomes too large, and the design is great. Is also not preferred. Therefore, the gap S is preferably 0.2 to 1.0 mm, and preferably 0.2 to 0.5 mm.

  The operation of the above embodiment will be described below.

  When the battery cover 6 in the closed state in FIG. 2 is removed from the first housing 1 and the battery housing recess 5 is opened, the vicinity of the front end of the upper surface of the battery cover 6 is pressed with a finger toward the rear of the first housing 1. Then slide the battery cover 6. Then, the hook 11 is deformed and unlocked from the locking opening 8 and pulled out from the locking opening 8. At the same time, the tongues 12 are pulled out from the lifting prevention holes 9 and 10, respectively. Thus, the battery cover 6 is removed from the first recess 51.

  At this time, since the notch 15 is provided at the boundary between the inner surface 6 a and the side surface 6 b of the battery lid 6, especially when the battery lid 6 is removed from the first recess 51, the notch 15 is the first. Since it rises smoothly along the side surface 51c of the recess 51, even if the planar shape of the first recess 51 is tapered, the problem that the battery cover 6 is caught on the first housing 1 is prevented. Therefore, it is possible to reduce the problem that the first casing 1 is scratched and the battery lid 6 is scraped off.

  As shown in FIG. 3, the configuration in which the notch 15 is provided at the boundary between the inner surface 6a and the side surface 6b of the battery lid 6 has the boundary line 14 formed on the rear surface A as shown in FIG. In addition to the method described above, the present invention can also be applied to the case where the boundary line 13 is provided on the side surface of the first housing 1 as in the conventional configuration shown in FIGS. .

  In addition, when the battery cover 6 is attached to the first recess 51 from the state shown in FIG. 1, the battery cover 6 is placed behind the closed position above the first recess 51, and then the upper front end of the battery cover 6. While pressing the vicinity of the part with a finger, slide toward the front of the first housing 1. Then, the hook 11 is deformed and inserted into the locking opening 8, and the tongues 12 are inserted into the lifting prevention holes 9, 10. The battery cover 6 is fixed to the first casing 1 by being locked in the locking opening 8, and the battery cover 6 is restrained in the front-rear direction, the left-right direction, and the upper-lower direction.

  Further, in the conventional mobile phone, it is required to make the clearance at the boundary line 13 between the first casing 1 and the battery lid 6 as small as possible. However, in the present invention, the side surface 6b of the battery lid 6 and the first recess 51 A required gap S was provided between the side surface 51c. That is, as shown in FIG. 2, the boundary line 14 between the side surface 6b of the battery cover 6 and the side surface 51c of the first recess 51 is located within the back surface A of the mobile phone, Therefore, there is no problem even if the gap S in the boundary line 14 is relatively large, for example, about 0.2 to 1.0 mm.

  When the gap S is provided in the boundary line 14 in this manner, the battery lid 6 is easy to move in the first recess 51 particularly when the planar shape has a tapered battery lid 6 and the first recess 51. The battery cover 6 can be attached and detached more smoothly, so that the problem due to rubbing can be further reduced and the boundary line 14 does not require high accuracy, and the manufacture is facilitated.

  In the above embodiment, the cellular phone is exemplified. However, the present invention can be applied to a battery storage device including various electronic devices such as a PDA other than the cellular phone, a remote controller, a cordless telephone cordless handset, and a notebook personal computer. Of course, various changes can be made without departing from the scope of the present invention.
