Description

  The present invention relates to an electronic device, and more particularly to an electronic device using a detachable battery as a power source.

  Conventionally, many handheld terminals, digital cameras, digital video cameras, notebook personal computers, PDAs, and other portable electronic devices use batteries such as dry batteries and rechargeable batteries as the power source, and the battery pack is detachably held. Most can be done.

  The battery pack is held in such a device by storing the battery pack in the battery storage part of the electronic device, and then pressing the battery pack directly with a battery cover that is rotatably held by a hinge. There is a battery that holds a battery by locking a lock member provided on a cover to an electronic device main body.

  In addition, the battery housing portion of the electronic device is provided with a battery internal lock member. After holding the battery pack with the internal lock member, the battery cover is covered with a rotatable battery cover, and the lock member provided on the battery cover is electronically connected. A structure is also known that is held by being locked to the device body. Or, further, in Japanese Patent No. 3088349, a fixing rib for the battery internal lock member is provided on the battery cover to suppress the return of the battery internal lock member (see, for example, Patent Document 1).

  As a lock mechanism for the lock member provided in such a battery cover, a mechanism for rotating or sliding the lock member using an opening / closing knob having a hook portion to lock the electronic device main body inside or outside thereof is known. ing.

In addition, in a drip-proof electronic device, a packing is attached to the battery cover, and when the cover is closed, the cover presses the packing in the direction in which the battery is pressed and deforms by preventing the ingress of water. In order to enhance the droplet performance, a seal structure is known in which the packing is sandwiched between the electronic device body and the cover so that the direction in which the packing is pressed is perpendicular to the direction in which the cover presses the battery. ing.

  Next, the structure of the battery housing will be described in detail with reference to FIG.

  FIG. 2 is a partial cross-sectional view of the battery housing portion in FIG. 1 and shows a case where the battery cover is opened.

  In FIG. 2, a battery guide portion 14 for guiding four side surfaces of the battery pack 13 is formed in the battery storage portion 12 of the handy terminal body 1. The battery guide portion 14 is formed in a shape substantially corresponding to the outer shape of the battery pack 13.

  A battery presser spring 15 such as a trapezoidal coil spring is held as an elastic member at the bottom (left side in FIG. 2) of the battery storage unit 12 with one end sandwiched between ribs 16 provided on the battery guide unit 14. It is attached with. The spring 15 serves to fix the battery pack 13 in cooperation with the battery cover 4 when the battery cover 4 is closed, and to pop up the battery pack 13 when the battery cover 4 is opened. It should be noted that terminals 17 and 18 for deriving an electromotive force are provided on the upper surface (or other appropriate position) of the battery pack 13, and the main body when the battery pack 13 is accommodated at a fixed position of the battery accommodating portion 12. Electrically coupled to the terminal on the side.

  Further, the battery storage unit 12 is provided with a battery internal lock member 23 for holding the battery pack 13 when the battery pack 13 is stored. The battery internal lock member 23 is made of a resin elastic material such as polyacetal, and is held on the side wall (battery guide portion 14) side of the battery storage portion 12 so as to be sandwiched between ribs 24 inside the handy terminal main body case. The battery internal lock member 23 is interlocked with the accommodating operation of the battery cover 4 and the battery pack 13 as described later.

  As shown in FIG. 3, an engagement portion 26 is provided at the tip portion 25 of the battery internal lock member 23, and this engagement portion 26 is engaged with the lock claw 20 as described later, for example, It has a slit shape.

  The battery internal lock member 23 may be formed from a metal steel strip for a spring or the like, or may be integrally formed as a part of the battery guide portion 14.

  FIG. 4 is a diagram showing a schematic structure of the battery cover in FIG.

  In FIG. 4, the battery cover operating knob 5 is fixed to the battery cover 4 with a hook-like lock claw 20 so as to sandwich a plate 21 for giving a click feeling with a screw 19. Accordingly, the lock claw 20 can also be rotated in conjunction with the rotation operation of the battery cover operation knob 5. Further, the battery cover 4 is provided with a rib 22 for operating the battery pack 13 to be pushed into the battery housing portion 12 when the battery cover 4 is closed to the handy terminal body 1 (FIG. 6).

  Next, the opening / closing operation of the battery cover 4 will be described.

  In FIG. 1, when the operation knob 5 is rotated in the direction of the arrow 27 until the end 28 of the operation knob 5 comes into contact with the stopper 29 of the battery cover 4, as shown in FIG. 4, the operation knob 5 is fixed to the operation knob 5 with a screw 19. The lock claw 20 thus rotated simultaneously rotates, and the engagement portion 26 with the battery internal lock member 23 is released, whereby the lock of the battery internal lock member 23 with respect to the handy terminal body 1 is released.

  The battery cover 4 is rotatably supported by the handy terminal body 1 by a hinge 30. By rotating the battery cover 4 in the direction of an arrow 31 about the hinge 30, the battery cover 4 is shown in FIG. 4 opens.

  Next, the operation of mounting the battery pack 13 on the handy terminal body 1 will be described with reference to FIGS.

  As shown in FIG. 5, when the battery pack 13 is inserted in the direction of the arrow 32 as shown in FIG. When the front end portion 25 of the member 23 is pushed by the battery pack 13, the battery internal lock member 23 is deformed so as to be retracted by its own elasticity, and a movement space of the battery pack 13 is secured (state of FIG. 6). In this state, the battery pack 13 is not completely stored in a fixed position in the battery storage portion 12, and the battery internal lock member 23 is not locked to the end portion of the battery pack 13.

  When the battery pack 13 is further pushed into the handy terminal main body 1 in the direction of the arrow 32 from the state of FIG. 6, the battery pack 13 completely gets over the battery internal lock member 23. Then, the battery internal lock member 23 returns to the initial position (the state shown in FIG. 3) by its own elasticity and is hooked on the battery pack 13.

  As described above, the battery pack 13 is held at a fixed position in the battery storage portion 12 of the handy terminal body 1 by the elastic force of the spring 15.

  Next, as shown in FIG. 7, the battery cover 4 is rotated and closed in the direction of the arrow 31 a around the hinge 30, and the operation knob 5 provided on the battery cover 4 is rotated counterclockwise (counterclockwise with respect to the arrow 27). ), The lock claw 20 interlocked with the operation knob 5 also rotates in the direction of the arrow 33 at the same time and engages with the engaging portion 26 of the battery internal lock 23 (FIG. 8). As a result, the battery pack 13 is completely held on the handy terminal body 1.

  Even if the operation is properly performed, the battery 22 is locked by the rib 22 being pushed into the battery housing 12 by the closing operation of the battery cover 4 and the lock claw 20 is rotated. Since the member 23 is locked to the battery pack 13 and the battery pack 13 is locked and held in a fixed position, the lock member 23 is stored in an unreasonable position and deformed by forgetting to operate the battery internal lock member 23. It can be easily noticed by mistaken operation of the locking claw 20 without being damaged.

  In this embodiment, the rotary mechanism is shown as the lock mechanism. However, if the lock claw is configured to engage a part of the battery internal lock member so as to suppress the deformation of the battery internal lock member. For example, a configuration in which a part of the lock member and the lock claw are engaged so as to suppress deformation of the battery internal lock member 23 by another lock mechanism may be used.

  In the present embodiment, the shape of the engaging portion of the battery lock member may be other than the slit shape as long as it is a shape that engages with the locking means of the battery cover.

  Next, the drip-proof structure of the battery cover of the present invention will be described.

  As shown in FIG. 4, an O-ring 34 is fitted and sealed between the screw 19 and the battery cover 4 in order to prevent entry of water droplets and the like from the outside. As a result, the lock mechanism can also easily prevent intrusion of water droplets or the like. Further, as a sealing means for the outer periphery of the cover, as shown in FIG. 5, for example, a cover packing 35, which is an O-ring, is fitted around the battery cover 4. Then, when the battery cover 4 is closed, the electronic device main body and the cover packing 35 are nipped and pressed. As a result, the direction in which the cover packing 35 is pressed can be made to be a direction (radial direction) orthogonal to the direction in which the battery cover 4 presses the battery pack 13, and the battery cover 4 floats due to vibration, dropping, etc. Can be prevented.

  In addition, if the lock mechanism of the rotating battery cover is used, the internal mechanism such as the lock claw can be configured within the range of the rib height for fitting the cover packing 35, and the lock that locks outside the housing of the handy terminal. Compared with the mechanism, the protrusion amount of the battery cover can be prevented, and the battery housing portion 12 can be downsized while improving the sealing performance.

  In this embodiment, the case of a handy terminal is exemplified as an electronic device. However, the present invention is a digital camera, a digital video camera, a notebook personal computer, a PDA, a mobile printer, or any other type using a detachable battery as a power source. Needless to say, it can be applied to electronic devices.
