Abstract

PROBLEM TO BE SOLVED: To provide a mechanism capable of achieving smooth insertion of a battery into a battery storage unit while achieving downscaling of the electronic device and an improved degree of freedom for designing.SOLUTION: An electronic device includes: a battery storage unit 3 into which a battery 4 is stored so that the battery 4 can be inserted/unloaded into/from the battery storage unit 3; a lock member 5 supported rotatably between a locking position at which the lock member 5 locks an end portion opposite to an insertion direction of the battery 4 stored in the battery storage unit 3 and an unlocking position at which the lock member 5 unlocks the end portion; and an urging member 15 urging the lock member 5 toward the locking position. A rotary shaft 13 of the lock member 5 is supported to be movable in a direction away from the battery 4 stored in the battery storage unit 3.

Description

  The present invention relates to an electronic apparatus such as a digital camera having a battery storage unit.

  Some electronic devices such as digital cameras have a lock mechanism that prevents a battery stored in a battery storage unit from being detachable from moving in a direction opposite to the insertion direction.

  For example, as shown in FIG. 14, the rotation is performed between a locking position for locking the end opposite to the insertion direction of the battery 102 stored in the battery storage section 101 and a release position for releasing the locking. One having a lock member 103 that is movably supported has been proposed (Patent Document 1).

  In this proposal, the lock member 103 is rotatable about the rotation shaft 104 by a cam action with the drive member 106, and is directed toward the locking position via the drive member 106 by the biasing member 105. It is energized. Therefore, when the battery 102 is inserted from the battery insertion / extraction port 101a of the battery housing 101, the lock member 103 is rotated in the direction of the release position against the urging force of the urging member 105 as shown in FIG. And is retracted from the battery insertion / extraction port 101a of the battery storage unit 101.

JP 2010-186633 A

  However, in Patent Document 1, when the battery 102 is inserted into the battery housing portion 101, the lock member 103 needs to be rotated in the direction of the release position against the urging force of the urging member 105. The operation of inserting the battery 102 is troublesome.

  Further, since the battery 102 is thinned with the recent miniaturization of electronic devices, and the label 102a is directly wound around the battery cell, the battery 102 is placed between the label 102a and the bottom 102b of the battery 102 as shown in FIG. The groove 102c is generated in the groove. For this reason, when the battery 102 is inserted into the battery housing portion 101, the end of the lock member 103 is caught in the groove portion 102c, and the user needs to rotate the lock member 103 again in the direction of the release position. This will prevent smooth insertion.

  Furthermore, since there is a possibility that the battery 102 is erroneously inserted into the battery housing portion 101 when the lock member 103 is in the locking position (position in FIG. 14), in order to prevent deformation of the lock member 103, etc. It is necessary to make the wall thickness T of the distal end portion 103a of the lock member 103 relatively thick. This hinders downsizing of the device, and also reduces the degree of freedom in designing the battery cover that covers the battery insertion / extraction opening 101a of the battery storage unit 101 so that it can be opened and closed.

  Accordingly, an object of the present invention is to provide a mechanism for reducing the size of an electronic device and improving the degree of design freedom while allowing a battery to be smoothly inserted into a battery housing.

  In order to achieve the above object, an electronic device according to the present invention locks a battery storage part in which a battery is detachably stored and an end opposite to the insertion direction of the battery stored in the battery storage part. A locking member that is rotatably supported between a locking position to be released and a release position to release the locking; and a biasing member that biases the locking member toward the locking position. The rotation shaft of the lock member is supported so as to be movable away from the battery stored in the battery storage unit.

The The battery lid 2 is provided with a shaft 2 a, and the shaft 2 a is engaged with the hole 3 b of the battery housing 3.

  FIG. 3 is an exploded perspective view showing the relationship between the battery storage unit 3 and the lock member 5. FIG. 4 is a view showing a state in which the lock member 5 is incorporated in the battery storage unit 3. As shown in FIG. 3, guide portions 3 c and 3 d that guide the drive member 14 so as to be movable in the insertion and removal direction of the battery 4 are formed in the battery housing portion 3. The drive member 14 is formed of a high-sliding polymer material (for example, POM), and as shown in FIG. 3, at the end opposite to the insertion direction of the battery 4, An engaging cam portion 14c is provided. The drive member 14 is provided with a pair of shafts 14a and 14b that are guided along the guide portions 3c and 3d so as to be movable in the insertion / extraction direction of the battery 4.

  The lock member 5 is formed with a hole 5a through which the rotation shaft 13 passes, and both ends of the rotation shaft 13 passing through the hole 5a are respectively supported by elongated holes 3g and 3h formed in the battery housing portion 3. . As a result, the lock member 5 is engaged with the battery storage unit 3 at an engagement position (see FIG. 5) that engages an end of the battery storage unit 3 opposite to the insertion direction of the battery 4. It is supported so as to be rotatable between a release position (see FIG. 6) for releasing the locking.

  The long holes 3g and 3h formed in the battery housing part 3 are arranged with the longitudinal direction thereof obliquely intersecting the insertion direction of the battery 4. Further, in the present embodiment, the urging member 15 is constituted by a compression coil spring, and is externally attached to the drive member 14 to urge the lock member 5 toward the locking position via the drive member 14. .

  FIG. 5 is a cross-sectional view of the main part showing a state in which the battery 4 stored in the battery storage unit 3 is locked by the lock member 5. FIG. 6 is a main part sectional view showing a state in which the battery 4 is taken out from the battery housing part 3, and FIG. 7 is a main part sectional view showing a state after the battery 4 is taken out from the battery housing part 3.

  In the state of FIG. 5, the lock member 5 is rotated in the direction of the arrow in the figure (clockwise direction) by the urging force of the urging member 15, and the battery 4 with the tip 5 c stored in the battery storage 3 is inserted. Lock the end opposite to the direction. At this time, the rotation shaft 13 of the lock member 5 is in contact with one end portion in the longitudinal direction of the long holes 3g, 3h formed in the battery housing portion 3, specifically, the end portion in the direction close to the battery 4. Touch.

  When the lock member 5 is rotated in the arrow direction (counterclockwise direction) in the figure against the urging force of the urging member 15 with a finger or the like as shown in FIG. The battery 4 is unlocked by the tip 5c. Further, the cam portion 14c of the drive member 14 is pushed in by the cam surface 5b of the lock member 5, and the drive member 14 moves in the insertion direction of the battery 4 along the guide portions 3c and 3d. When the locking of the battery 4 by the distal end portion 5c of the lock member 5 is released, the battery 4 is moved in the direction opposite to the insertion direction of the battery 4 by the biasing force of the biasing spring 6, and It protrudes from the insertion / extraction opening 3a and can be taken out from the battery storage unit 3.

  After removing the battery from the battery housing 3 and releasing the finger or the like from the lock member 5, the lock member 5 is rotated in the same direction as FIG. 5 by the biasing force of the biasing member 15, as shown in FIG. To return to the original position. At this time, the protrusion 5d provided at the base end portion of the lock member 5 abuts on the engaging portion 3j of the battery housing portion 3, and further rotation of the lock member 5 is restricted.

  FIG. 8 is a cross-sectional view of the main part showing a state when the battery 4 is inserted into the battery housing part 3. As shown in FIG. 8, the lock member 5 is disposed at the position of the two-dot chain line in the figure after the battery 4 is taken out from the battery housing 3. When the battery 4 is inserted into the battery housing part 3 from the insertion / extraction opening 3a, the tip of the battery 4 comes into contact with the inclined surface 5e formed on the tip 5c of the lock member 5, and the inclined surface 5e is biased. Push against 15 biasing forces. At this time, the lock member 5 is moved to the other end of the long holes 3h, 3g along the long holes 3h, 3g, and the lock member 5 is located at the position indicated by the solid line in FIG. Placed in. As a result, the battery 4 can be smoothly inserted into the battery housing 3.

  Here, in this embodiment, the angle α formed by the insertion direction of the battery 4 and the longitudinal direction of the long holes 3h, 3g is approximately 45 °. The angle α is an angle at which the lock member 5 can be retracted to a position where the tip 5c of the lock member 5 does not prevent the battery 4 from being inserted when the battery 4 is inserted into the battery housing 3a.

  In the present embodiment, the angle α formed between the insertion direction of the battery 4 and the longitudinal direction of the long holes 3h, 3g is not particularly limited as long as the lock member 5 can be retracted to a position that does not hinder the insertion of the battery 4. Alternatively, instead of the long hole, an arc-shaped hole may be used.

  The inclined surface 5e formed at the tip 5c of the lock member 5 is shaped to guide the battery 4 to the inside of the battery housing 3 when the battery 4 is inserted, and the lock member extends in a direction substantially normal to the inclined surface 5e. The angle of the long holes 3h and 3g with respect to the insertion direction of the battery 4 is set so that 5 is retracted. That is, in the present embodiment, the normal direction of the inclined surface 5e and the longitudinal direction of the long holes 3h, 3g are substantially the same direction. Thereby, the force received by the inclined surface 5e of the lock member 5 from the battery 4 can be changed to the force for retracting the lock member 5, and the battery 4 can be inserted more smoothly.

  Further, in order to make the insertion of the battery 4 even smoother, the battery 4 is inserted into the opening edge of the insertion / extraction port 3a of the battery storage part 3 facing the tip part 5c of the lock member 5 with the battery 4 interposed therebetween. You may provide the guide groove 3k guided to the inside. As a result, when the battery 4 is inserted, the position where the battery 4 abuts against the inclined surface 5e of the lock member 5 is brought closer to the distal end portion 5c side (left side in the figure) of the lock member 5 and necessary for the insertion of the battery 4. The retraction amount of the lock member 5 can be reduced, and as a result, the battery 4 can be inserted more easily.

  FIG. 9 is a cross-sectional view of a main part for explaining a rotation restricting portion of the lock member 5 in a state where the lock member 5 is retracted. In the state in which the lock member 5 is retracted, the contact between the protrusion 5d of the lock member 5 and the engaging portion 3j of the battery housing portion 3 is released, and the lock member 5 is rotated clockwise by the biasing force of the biasing member 15. Rotation restriction is eliminated. For this reason, in the present embodiment, with the lock member 5 retracted, the inclined surface 5f formed at the base end portion of the lock member 5 is brought into contact with the locking surface 3p formed at the battery housing portion 3, thereby attaching The rotation of the lock member 5 in the clockwise direction by the urging force of the urging member 15 is restricted.

  FIG. 10 is a cross-sectional view of the main part showing a state in the middle of inserting the battery 4 into the battery housing part 3. As shown in FIG. 10, in the middle of inserting the battery 4 into the battery housing portion 3, the front end portion 5 c of the lock member 5 is caught in the groove portion 4 c between the label 4 a and the bottom portion 4 b of the battery 4. Here, in the present embodiment, the lock member 5 is retracted in the direction away from the battery 4 along the long holes 3h and 3g by further pushing the battery 4 in the insertion direction (the upper side in the figure) in the state of FIG. Thus, the distal end portion 5c of the lock member 5 is easily detached from the groove portion 4c.

  FIG. 11 is a cross-sectional view of the main part in a state where the battery 4 is stored in the battery storage unit 3 built in the digital camera 1. In the present embodiment, when the battery 4 is inserted into the battery housing 3, the lock member 5 is separated from the battery 4 even if the battery 4 comes into contact with the tip 5 c of the lock member 5 and receives external force from the battery 4. Move in the direction. For this reason, the possibility of deformation or breakage of the distal end portion 5c of the lock member 5 is reduced, unnecessary strength becomes unnecessary, and the thickness of the distal end portion 5c can be made relatively thin. As a result, the digital camera 1 can be miniaturized, and the battery lid 2 that covers the insertion / extraction opening 3a of the battery storage unit 3 so as to be openable / closable, and thus the design freedom of the digital camera 1 is improved.

  As described above, in the present embodiment, the digital camera 1 can be downsized and the degree of design freedom can be improved while allowing the battery 4 to be smoothly inserted into the battery housing 3.
