Description

  The present invention relates to a holding structure and an electronic apparatus having the holding structure.

  In an electronic device such as a portable terminal that holds a battery therein, there is often a gap between the battery and the main body in order to ensure the detachability of the battery or due to the influence of dimensional variation that occurs during manufacturing. In this case, when an impact is applied to the electronic device from the outside, the battery is loose in the electronic device. As a result, the contact between the battery electrode and the battery terminal of the electronic device main body is cut off, causing a problem that the power is cut off or restarted.

  As a countermeasure for this problem, a method of fixing the battery by providing a cushion in the electronic device can be considered. However, when a cushion is added, there is a problem that not only the number of parts is increased, but also the backlash of the battery cannot be sufficiently prevented.

  Furthermore, a method of fixing the battery by providing a spring or a leaf spring in the electronic device is also conceivable. However, when such a member is added, the structure for holding the battery becomes complicated, the number of parts increases, and the electronic apparatus becomes large.

  For example, Patent Document 1 discloses a technique for attaching a battery cover to an electronic device main body in which a battery is stored.

  The electronic device described in Patent Literature 1 includes a main body that holds a battery and a battery cover that is attached to the main body. The main body and the battery cover are each formed with a claw portion, and the claw portion on the battery cover side is supported by a claw support that is elastically deformed. And when attaching a battery cover to a main body, a battery cover is fixed because each nail | claw part fits.

Japanese Patent Laid-Open No. 11-016553

  However, in the electronic device described in Patent Document 1, although the battery cover is fixed to the electronic device main body, the battery itself is only held by being fitted into the battery receiving portion on the main body side. For this reason, it is impossible to sufficiently prevent the backlash of the battery in the electronic device. Further, in the electronic device described in Patent Document 1, in order to attach and detach the battery cover and the electronic device main body, an elastically deformed claw support must be formed on the battery cover.

  In view of such a problem, the present invention can prevent rattling of a held member with a small number of parts, and can easily attach and detach the held member, and an electronic device including the holding structure The purpose is to provide equipment.

  A holding structure of the present invention includes a held member having a claw portion, a groove portion and a claw receiving portion formed inside the groove portion, and a holding member that stores and holds the held member in the groove portion. A predetermined gap is formed between the claw receiving portion and the inner surface of the groove portion, and the fitting surface between the claw portion and the claw receiving portion is perpendicular to the direction in which the member to be held is inserted into the groove portion. Is inclined.

  The electronic device of the present invention has the holding structure.

  As described above, in the holding structure 10 according to the present embodiment, the holding member 12 is held by the fitting of the claw portion 13 of the held member 11 and the claw receiving portion 14 formed inside the groove portion of the holding member 12. The member 11 is held. Therefore, it is possible to prevent the held member 11 from rattling in the groove of the holding member 12. Further, the fitting surface between the claw portion 13 and the claw receiving portion 14 is inclined with respect to the vertical direction of the insertion direction with respect to the groove portion of the held member 11. Therefore, it is possible to easily attach and detach the holding member 12 without newly adding parts such as an elastic body.

  Further, since the claw receiving portion 14 is formed inside the groove portion of the holding member 12, the held member 11 can be accommodated in the holding member 12 without increasing the size of the holding member 12.

  In addition, although the holding structure 10 of this embodiment was set as the structure provided with the nail | claw part 13 and the nail | claw receiving part 14, respectively, it is not restricted to this. That is, a plurality of claw portions may be formed on the held member 11, and a plurality of claw receiving portions may be formed on the holding member 12, each of which is fitted with any one of the claw portions.

[Second Embodiment]
The holding structure in the second embodiment of the present invention will be described. A cross-sectional view of the structure of the holding structure 20 in this embodiment is shown in FIG.

  The holding structure 20 in this embodiment includes a battery 21 that is a member to be held, a holding member 22 that holds the battery 21, and a holding cover 23.

  The battery 21 includes a claw portion 24, a tab 25, and an electrode 26. The tab 25 has flexibility and protrudes in a direction in which the battery 21 is detached from the holding member 22 from the surface of the battery 21 where the claw portion 24 is formed.

  The holding member 22 is formed with a groove portion for accommodating the battery 21, and has a claw receiving portion 27 and a battery terminal 28 inside the groove portion. Further, the claw receiving portion 27 and the inner side surface (surface A) of the groove portion are separated by a predetermined distance. That is, in a state where the insertion portion 29 described later is not inserted, a gap is generated between the claw receiving portion 27 and the inner side surface of the groove portion.

  The holding cover 23 covers the battery 21 housed in the groove portion of the holding member 22 and is fixed to the holding member 22. The holding cover 23 includes an insertion part 29. When the holding cover 23 is fixed to the holding member 22, the insertion portion 29 is inserted into the gap between the claw receiving portion 27 and the surface A and comes into contact with the claw receiving portion 27.

  As described above, in the holding structure 20 in the present embodiment, the insertion portion 29 of the holding cover 23 is inserted between the claw receiving portion 27 and the inner surface of the groove portion. Therefore, even when a force in the direction of arrow B is applied to the claw receiving portion 27 by applying some impact to the holding structure 20 in a state where the battery 21, the holding member 22, and the holding cover 23 are assembled, the nail It is possible to prevent the receiving portion 27 from being inclined in the direction of the arrow B. Thereby, since the battery 21 can be prevented from rattling inside the holding structure 20, the connection between the electrode 26 and the battery terminal 28 is hardly cut off.

  That is, the holding structure 20 in the present embodiment can prevent the connection between the electrode 26 of the battery 21 and the battery terminal 28 of the holding member 22 from being disconnected when an impact is applied from the outside.

  On the other hand, when the holding cover 23 is removed, a gap is generated between the claw receiving portion 27 and the inner surface (surface A) of the groove portion of the holding member 22. Further, the tab 25 is exposed on the surface. Furthermore, the fitting surface (surface B) between the claw portion 24 and the claw receiving portion 27 is inclined. Therefore, by pulling the tab 25 in the direction of arrow C with the holding cover 23 removed, the fitting of the claw portion 24 and the claw receiving portion 27 can be removed. Thereby, the battery 21 can be easily taken out.

  In FIG. 4, the electrode 26 and the battery terminal 28 are formed at positions facing the claw portion 24 and the claw receiving portion 27, but this is not restrictive. That is, the electrode 26 and the battery terminal 28 may be in a position where they can be connected to each other.

  Furthermore, when the nail | claw part 24 and the nail | claw receiving part 27 in this embodiment are fitted, when removing a fitting, the nail | claw receiving part 27 should just incline in the direction of arrow B. Therefore, unlike Patent Document 1, it is not necessary to use a material that is elastically deformed as a part of the structure. That is, the claw part 24, the claw receiving part 27, the holding member 22, and the holding cover 23 in the present embodiment can all be formed using the same material, for example, engineering plastic. Therefore, it becomes possible to manufacture by a simple manufacturing method.

  In addition, although the to-be-held member in the holding structure 20 of this embodiment is a battery, it is not limited to this. That is, the structure of this embodiment can be applied as long as the structure is held by the holding member in the groove portion of the held member. Further, in the case where the held member is configured to be electrically or optically connected to the holding member by being housed in the groove portion of the holding member, the holding member and the held member are applied by applying the holding structure in the present embodiment. It is possible to prevent the electrical or optical connection with the sensor from being broken by an external impact.

[Third Embodiment]
Next, an electronic apparatus according to the third embodiment of the present invention will be described. The structure and operation of the mobile terminal 100, which is an electronic device in the present embodiment, will be described with reference to FIGS. Note that the mobile terminal 100 includes the holding structure 20 in the second embodiment.

  5 and 6 are views of the state before assembling the holding member 22, the battery 21, and the holding cover 23 of the mobile terminal 100 from different angles. FIG. 7 shows the structure of the back surface of the holding cover 23. 8 to 10 show a state in the middle of storing the battery 21 in the holding member 22. FIG. 11 is a cross-sectional view of the mobile terminal 100 in a state where the battery 21 is housed in the holding member 22.

  As shown in FIGS. 5 and 6, the holding member 22 of the mobile terminal 100 includes a front case 35 and a rear case 36, and a groove is formed by the rear case 36. In addition to the claw receiving portion 27 and the battery terminal 28, the groove portion includes a concave portion 30, a reverse insertion preventing rib 31, and a holding cover fixing portion 32. In addition to the claw portion 24, the tab 25, and the electrode 26, the battery 21 includes a convex portion 33 and a reverse insertion preventing concave portion 34. The convex portion 33 engages with the concave portion 30 when the battery 21 is accommodated in the groove portion of the holding member 22. The reverse insertion prevention rib 31 engages with the reverse insertion prevention recess 34.

  As shown in FIGS. 7A and 7B, the holding cover 23 of the mobile terminal 100 includes an insertion portion 29 and a locking portion 37 on the back surface, that is, the surface facing the battery 21. The locking portion 37 engages with the holding cover fixing portion 32 when the holding cover 23 is fixed to the holding member 22. FIG. 7C is an enlarged view of the shape of the insertion portion 29 in the range drawn by the dotted line in FIG. In FIG. 7C, for the sake of convenience, the insertion portion 29 is indicated by hatching, but this does not mean that only the hatched portion is manufactured by a different material or process. That is, the insertion portion 29 may be integrally formed with other portions of the holding cover 23.

  In the holding structure 20 in the present embodiment, at least the front case 35, the rear case 36, the claw portion 24, the claw receiving portion 27, and the holding cover 23 are made of engineering plastic.

  The tab 25 is made of a flexible material such as paper or a thin plastic sheet. For example, the tab 25 may be an extension of a label wound around the battery 21.

  Next, an operation when the battery 21 is stored in the holding member 22 of the mobile terminal 100 will be described.

  When the battery 21 is housed in the groove portion of the holding member 22, as shown in FIG. 8, first, the surface of the battery 21 on which the claw portion 24 is not formed is inserted into the groove portion. FIG. 9A shows the state of FIG. 8 viewed from directly above the mobile terminal 100. FIG. FIGS. 9B and 9C are cross-sectional views taken along lines AA ′ and BB ′ in FIG. 9A, respectively. As shown in FIGS. 9B and 9C, in the state of FIG. 8, the convex portion 33 of the battery 21 is engaged with the concave portion 30 of the holding member 22. Further, the electrode 26 of the battery 21 is in contact with the battery terminal 28 of the holding member 22.

  In the state shown in FIG. 9C, when the battery 21 is pushed in the direction of arrow A, the claw portion 24 of the battery 21 is fitted into the claw receiving portion 27 of the holding member 22. FIG. 10 shows an enlarged view of a state immediately before the claw portion 24 and the claw receiving portion 27 are fitted.

  As shown in FIG. 10, when the battery 21 is pushed in the direction of arrow A, the claw receiving portion 27 is pushed in the direction of arrow B by the claw portion 24. Thereby, the claw receiving portion 27 is inclined toward the inner side surface (surface A) of the groove portion of the holding member 22. When the battery 21 is further pushed in the direction of arrow A from this state, the claw portion 24 and the claw receiving portion 27 are fitted. The battery 21 is accommodated in the holding member 22 as described above.

  Then, the holding cover 23 is fixed to the holding member 22 from the direction of the arrow A in a state where the battery 21 is stored in the holding member 22. At this time, the locking portion 37 engages with the holding cover fixing portion 32 of the holding member 22. Further, the insertion portion 29 is inserted into the gap between the claw receiving portion 27 and the inner side surface (surface A) of the groove portion in the groove portion of the holding member 22. FIG. 11 shows a cross-sectional view taken along line AA ′ after the holding cover 23 is fixed to the holding member 22.

  As described above, the assembly of the battery 21, the holding member 22, and the holding cover 23 is completed.

  As shown in FIG. 11, an insertion portion 29 of the holding cover 23 is inserted between the inner side surface (surface A) of the groove portion of the holding member 22 and the claw receiving portion 27 in the mobile terminal 100. Therefore, when the holding cover 23 is attached, the fitting between the claw portion 24 and the claw receiving portion 27 cannot be removed. Thereby, even when an impact is applied to the mobile terminal 100, the battery 21 can be prevented from rattling inside the holding member 22. Therefore, it can be prevented that the connection between the electrode 26 and the battery terminal 28 is disconnected due to the drop of the mobile terminal 100 and the power of the mobile terminal 100 is cut off.

  On the other hand, when the holding cover 23 is removed from the holding member 22, a gap is generated between the claw receiving portion 27 and the inner side surface (surface A) of the groove portion of the holding member 22, and the tab 25 is exposed. Moreover, since the fitting surface (surface B) of the claw part 24 and the claw receiving part 27 is inclined, when the battery 21 is pulled in the direction of the arrow C, the fitting is released. Therefore, the battery 21 can be taken out from the holding member 22 by pulling the tab 25 in the direction of arrow C.

  As described above, in the present embodiment, since the claw portion 24 and the claw receiving portion 27 of the battery 21 are fitted, it is possible to prevent the battery 21 from rattling in a state where it is stored in the groove portion of the holding member 22. Can do. Further, since the fitting surface between the claw portion 24 and the claw receiving portion 27 is inclined, the battery 21 can be easily attached to and detached from the holding member 22.

  Further, in the present embodiment, an insertion portion 29 is formed in the holding cover 23 that is fixed to the holding member 22. The insertion portion 29 is inserted between the inner surface of the groove portion of the holding member 22 and the claw receiving portion 27, thereby preventing the claw receiving portion 27 from being inclined. Therefore, it is possible to further prevent the battery 21 from rattling when the holding cover 23 is attached.

  In addition, since the holding portion 23 is formed with the insertion portion 29 that prevents the claw receiving portion 27 from being inclined, if the holding cover 23 is removed, the claw portion 24 and the claw receiving portion 27 are fitted to each other. It is also possible to remove.

  In the present embodiment, a tab 25 is formed so as to protrude in a direction in which the battery 21 is detached from the holding member 22 from the surface of the battery 21 where the claw portion 24 is formed. Therefore, the battery 21 can be easily removed from the holding member 22 by pulling the tab 25.

  In the present embodiment, the rear case 36 and the claw receiving portion 27 are both formed of engineering plastic. Therefore, since both can be integrally molded, the portable terminal 100 can be downsized and the manufacturing process can be simplified.

  In addition, although the front case 35, the rear case 36, the claw part 24, the claw receiving part 27, and the holding cover 23 in the present embodiment are all formed of engineering plastic, the present invention is not limited thereto. For example, the claw receiving portion 27 may be formed of a sheet metal such as a stainless sheet metal. In this case, the claw receiving portion 27 is formed integrally with the rear case 36 formed from engineering plastic, for example, by insert molding.

  When sheet metal is used for the claw receiving portion 27, the claw receiving portion 27 can be formed thinner than when engineering plastic is used. That is, the thickness d of the claw receiving portion 27 in FIG. 11 can be further reduced. Thereby, it becomes possible to further reduce the size of the holding member 22 as a whole. Further, by forming the claw receiving portion 27 with a metal plate having a spring property such as a stainless steel plate, the claw portion 24 is more firmly held by the claw receiving portion 27 and the fitting is not easily released. Further, even when the battery 21 and the holding member 22 are repeatedly attached and detached, the fitting property between the claw portion 24 and the claw receiving portion 27 is unlikely to deteriorate.

  Further, the claw receiving portion 27 may be formed of a resin having rubber elasticity such as an elastomer. In this case, the claw receiving portion 27 is formed integrally with the rear case 36 formed from engineering plastic, for example, by two-color molding. By using a resin having rubber elasticity for the claw receiving portion 27, the claw receiving portion 27 is more easily bent, and therefore the detachability between the battery 21 and the holding member 22 is further improved. Further, even when only the claw receiving portion 27 is formed of an elastomer or the like, it is formed integrally with the rear case by two-color molding, so that the whole is molded in the same size as that formed by engineering plastic. It becomes possible.

  In the present embodiment, when the holding cover 23 is fixed to the holding member 22, the insertion portion 29 is in contact with the claw receiving portion 27. However, the present invention is not limited to this. For example, the claw receiving part 27 may be inclined and may be separated by a distance that is narrower than a gap necessary for disengaging the fitting between the claw receiving part 27 and the claw part 24. That is, when the claw receiving portion 27 is inclined due to some kind of impact, the insertion portion 29 and the claw receiving portion 27 come into contact with each other, so that the nail receiving portion 27 is inclined to the extent that the fitting between the claw receiving portion 27 and the claw portion 24 is released. It only has to be prevented. However, even if the fitting between the claw receiving portion 27 and the claw portion 24 is not released, it is considered that the ratchet portion 27 is inclined to cause some backlash in the battery 21. Therefore, it is preferable that the insertion portion 29 has a structure in contact with the claw receiving portion 27.

  Moreover, it is good also as the portable terminal 100 with a waterproof function by forming the waterproof packing 38 in the portable terminal 100 in this embodiment. For example, as shown in FIG. 11, the waterproof packing 38 may be formed outside the insertion portion 29 of the holding cover 23.

  Moreover, although the electronic device in this embodiment was a portable terminal, it is not restricted to this. That is, the holding structure in the first embodiment and the second embodiment can be applied not only to a portable terminal but also to various electronic devices that are driven by a battery, such as a camera or an electronic dictionary.
