Description

  The present invention relates to a battery mounting mechanism of an electronic device.

  There exists patent document 1 as a prior art document regarding the battery mounting mechanism of an electronic device. The battery mounting mechanism described in Patent Literature 1 includes a battery housing recess and a lid that opens and closes the battery housing recess with a hinge portion as a fulcrum in a housing of an electronic device. Is positioned at the mounting position of the battery housing recess.

  In the battery mounting mechanism described in Patent Document 1, when the lid is closed, a part of the lid presses the battery in conjunction with this operation to position the battery at the mounting position of the battery housing recess, and the battery electrode. Can be electrically connected to the electrode terminal of the battery housing recess.

  However, backlash due to the opening / closing mechanism inevitably occurs in the lid. This looseness makes the connection between the electrode of the battery and the electrode terminal of the electronic device unstable when the electronic device vibrates. Therefore, an electronic device having a lock claw that positions the battery independently of the lid is known.

  An example of an electronic device provided with a lock claw will be described. FIG. 4 is a perspective view showing a state where the digital camera 400 is placed upside down. The lid 401 is open. The battery 410 is housed in the battery housing recess 403 while sliding the lock claw 402 in the direction indicated by the arrow F. Since the lock claw 402 is biased in the direction opposite to the direction indicated by the arrow F, when the battery 410 is completely received in the battery receiving recess 403, the lock claw 402 slides in the direction opposite to the direction indicated by the arrow F. Then, the battery 410 is positioned.

  A biasing member (not shown) that biases the battery 410 in the direction of pushing out is provided on the bottom surface of the battery housing recess 403. Since the direction in which the locking claw 402 slides and the direction in which the battery 410 is accommodated indicated by the arrow G are orthogonal, the locking claw 402 can stably position the battery 410. The urging member facilitates removal of the battery 410 and prevents the battery 410 from vibrating by pressing the battery 410 against the lock pawl 402.

JP-A-7-67007

  In order to accommodate the battery in the battery accommodating recess of the electronic device provided with the lock claw, 1) open the lid, 2) slide the lock claw, 4) accommodate the battery, and 4) close the lid. , Four operations are required, which is troublesome. Further, if the lid is closed without confirming that the lock claw has positioned the battery, the connection between the battery electrode and the electrode terminal of the electronic device becomes unstable during the operation of the electronic device.

  Here, when a mechanism for forcibly pushing the battery to the positioning position by the lock claw is adopted by applying the battery mounting mechanism described in Patent Document 1 to an electronic device having a lock claw, a part of the lid is locked. It must be a mechanism that pushes the battery beyond the battery positioning position by the claw.

  Then, the battery positioning position by the lock claw is set to a position where the biasing force of the biasing member provided on the bottom surface of the battery housing recess and the connection stability between the battery electrode and the electrode terminal of the electronic device are balanced. In spite of this, the battery is pushed beyond this, so that an excessive load is applied to the urging member, and the aging of the urging member is a concern.

  In addition, in a state where the lid portion is closed, a state where a part of the lid portion presses the battery is maintained, so that the backlash caused by the opening / closing mechanism is directly transmitted to the battery, and the lock claw is provided separately and independently. Significance is halved.

  An object of the present invention is to solve the above-described problems and to provide a battery mounting mechanism that facilitates battery storage even in an electronic device having a lock claw and that reliably positions the battery with the lock claw. .

  In order to solve the above problems, a battery mounting mechanism according to the present invention includes a battery housing recess that houses a battery, and a lid that is pivotally supported adjacent to the battery housing recess and opens or closes the battery housing recess. The battery accommodating recess includes a lock claw biased to a position for positioning the battery in the vicinity of the opening, and the lid includes a battery receiving portion that comes into contact with a corner of the battery.

  With this configuration, the battery receiving portion provided in the lid portion obliquely presses the battery against one side wall of the battery housing recess in accordance with the closing operation of the lid portion, and this pressing force is applied to the battery and the battery housing recess. When the static frictional force with one of the side walls is exceeded, the battery is pushed toward the bottom surface of the battery housing recess, so that the battery is reliably positioned by the lock claw biased to the position for positioning the battery. .

  As described above, according to the present invention, since the battery is reliably positioned by the closing operation of the lid, the battery can be easily housed even in the electronic device having the lock claw, and the battery is positioned by the lock claw. Thus, it is possible to provide a battery mounting mechanism that reliably performs the operation.

(Embodiment)
Hereinafter, embodiments in which the battery mounting mechanism of the present invention is adopted in a digital camera will be described in detail with reference to the drawings. A digital camera is an example of an electronic device.
(1. Configuration)
(1-1. Appearance)
FIG. 1 is a three-view diagram of a digital camera 100 that employs the battery mounting mechanism of the present invention. FIG. 1A is a front view, FIG. 1B is a rear view, and FIG. 1C is a bottom view. In the bottom view shown in FIG. 1C, the upper stage is a state in which the lid part 105 is closed, and the lower stage is a state in which the lid part 105 is opened. The lid 105 rotates 90 degrees or more to the front side of the drawing from the closed state shown in the upper part of FIG. 1C to the open state shown in the lower part of FIG.

  When the lens barrier 101 is slid in the direction indicated by the arrow A, the optical system is exposed and the digital camera 100 is turned on. Since the subject is displayed on the liquid crystal monitor 102, the image data of the subject can be obtained by determining the composition and pressing the shutter button 103. By operating the operation button group 104 in accordance with the menu screen displayed on the liquid crystal monitor 102, detailed settings relating to shooting and reproduction can be performed.

  A battery housing recess 109 for housing the battery 112 and the memory card 113 is provided on the bottom surface of the digital camera 100. In the closed state of the lid portion 105 shown in FIG. 1C, the lid portion 105 can be locked so as not to be opened by sliding the slide knob 106 to the LOCK side. On the other hand, in order to open the lid 105, the slide knob 106 may be slid to the OPEN side.

  As shown in the lower part of FIG. 1C, a battery receiving portion 107 that abuts against a corner portion of the battery 112 by a closing operation is provided on the back surface of the lid portion 105. The lid 105 is pivotally supported by a hinge 108 adjacent to the battery housing recess 109 so as to be rotatable.

In the open state of the lid 105 shown in the lower part of FIG. 1C, the battery 112 is positioned at the positioning position by the lock claw 110. In this state, the pressing portion 111 of the lock claw 110 is in contact with a part of the battery 112. When the locking claw 110 is slid in the direction shown by the arrow B, the holding portion 111 does not contact a part of the battery 112, so that the battery 112 is moved to the front side of the drawing by the urging member provided on the bottom surface of the battery housing recess 109 Extruded. Since the lock claw 110 is biased in the direction opposite to the direction indicated by the arrow B, the positioning of the battery 112 is not inadvertently released.
(2. Operation)
FIG. 2 is a cross-sectional view of a digital camera 100 employing the battery mounting mechanism of the present invention. A cross section including the battery 112 is shown in a state where the digital camera 100 is viewed from the front. Since the lens barrier 101 is excluded, the optical system 114 is visually recognized.

  The digital camera 100 is upside down. When the battery 112 or the memory card 113 is accommodated in the battery accommodating recess 109, the digital camera 100 is usually held upside down.

  2A to 2E show a state from the state in which the lid 105 is opened and the battery 112 is temporarily housed in the battery housing recess 109 to the state in which the lid 105 is closed and the digital camera 100 can be used. Shown in time series.

  FIG. 2A shows a state where the lid 105 is opened and the battery 112 is temporarily accommodated in the battery accommodating recess 109. The bottom surface of the battery 112 is in contact with the urging member 115 provided on the bottom surface of the battery housing recess 109, but no other force acts on the battery 112. The pressing portion 111 of the lock claw 110 is in contact with the side surface of the battery 112. Therefore, the lock claw 110 slides in the direction indicated by the arrow C against the urging force.

  FIG. 2B shows a state where the lid 105 is rotated clockwise around the hinge 108 provided at one end of the lid 105 and the battery receiving portion 107 is in contact with the corner of the battery 112. Even in this state, no force acts on the battery 112. The battery receiving portion 107 has a shape that receives the corner portion of the battery 112, but in order to smoothly rotate the lid portion 105 thereafter, the battery receiving portion 107 has a shape that is in close contact with the corner portion of the battery 112. Not. Further, the battery receiving portion 107 is increased in strength by making a part thereof a rib structure 116.

  Note that the battery receiving portion 107 may have a rib structure 116 as shown in FIG. 2 or may simply have a shape that abuts and holds the corner portion of the battery 112. Further, a concave portion may be provided in the lid portion 105 to hold the corner portion of the battery 112 in contact.

  FIG. 2C shows a state in which the lid 105 is further rotated clockwise from the state shown in FIG. The battery receiver 107 presses the battery 112 obliquely against the side wall 117 of the battery housing recess 109. An arrow D indicates this pressing force. In this state, the battery 112 and the battery housing recess 109 are slightly moved toward the bottom surface of the battery housing recess 109 against the biasing force of the biasing member 115 by the pressing force of the battery receiving portion 107. Since the static frictional force with the side wall 117 exceeds the pressing force by the battery receiving portion 107, the battery 112 is stationary.

  FIG. 2D shows a state in which the lid 105 is further rotated clockwise from the state shown in FIG. When the lid 105 is further rotated clockwise, the pressing force indicated by the arrow D is also rotated clockwise. Then, the component force D1 that presses the battery 112 against the side wall 117 of the battery housing recess 109 is relatively small, while the component force D2 that presses the battery 112 toward the bottom surface of the battery housing recess 109 is relatively large.

  Therefore, the component force D2 that presses the battery 112 toward the bottom surface of the battery housing recess 109 is generated by the component force D1 that presses the battery 112 against the side wall 117 of the battery housing recess 109, and the side wall 117 of the battery housing recess 109. When the static frictional force is exceeded, the battery 112 is pushed toward the bottom surface of the battery housing recess 109 against the urging force of the urging member 115. At the same time, the battery 112 is reliably positioned at the positioning position by the lock claw 110 biased in the direction indicated by the arrow E.

  At this time, if the lid portion 105 is made of an elastic material, the restoring force of the elastically deformed lid portion 105 acts as a force for pushing the battery 112 toward the bottom surface of the battery housing recess 109, It is effective. Further, the side wall 117 of the battery housing recess 109 has a component force D2 that presses the battery 112 toward the bottom surface of the battery housing recess 109, and a battery that is generated by a component force D1 that presses the battery 112 against the side wall 117 of the battery housing recess 109. A material that takes into consideration the balance point between the static frictional force between the battery 112 and the side wall 117 of the battery housing recess 109 may be used. For example, even if the battery housing recess 109 is molded of resin, it is conceivable that a sheet having a static friction coefficient different from that of the resin used for the battery housing recess 109 is attached to the side wall 117.

  FIG. 2E shows a state in which the battery housing recess 109 is closed by the lid 105. From this state, if the slide knob 106 of the lid 105 is slid to the LOCK side, the digital camera 100 can be used.

  In FIG. 2, since the operation of the lock claw 110 seems to be slightly difficult to understand, an enlarged view is shown. FIG. 3 is a diagram for explaining the operation of the lock claw 110. 3A is the same state as FIG. 2A, and FIG. 3B is the same state as FIG.

In FIG. 3A, the pressing portion 111 of the lock claw 110 is in contact with the side surface of the battery 112, and the lock claw 110 slides to the right side in the drawing against the urging force. On the other hand, in FIG. 3B, the lock claw 110 is slid to the left side of the drawing by the urging force to position the battery 112 at the positioning position.
(Other embodiments)
As described above, the embodiment in which the battery mounting mechanism of the present invention is adopted in the digital camera has been described. However, it goes without saying that the battery mounting mechanism of the present invention can be employed in various electronic devices using batteries. Further, the battery mounting mechanism of the present invention can be adopted not only for a rectangular battery but also for a cylindrical battery.

  According to the present invention, since the battery is reliably positioned by the closing operation of the lid, it can be employed in various electronic devices using a battery, such as a digital camera, a digital video camera, and a PDA.
