The present invention relates to a battery charger.

  A portable electronic device such as a cellular phone needs to be charged by a charging device. A conventional charging device that charges a conventional electronic device by placing it sideways with its side facing downward is not a structure in which the power terminal protrudes from the surface of the device installation recess on the upper surface of the charging stand, but the device installation recess The power supply terminal protrudes and is fixed in a protruding state, and a presser is protruded so as to be able to move up and down at a position adjacent to the surface of the device installation recess, and the electronic device that is turned sideways in the device installation recess It was the structure in which the hook mechanism which temporarily latches was provided (for example, refer patent document 1).

  In such a horizontal charging device, when an electronic device is placed in the device installation recess with the one side facing downward and is temporarily locked by the hook mechanism, the electronic device is pressed by the installation of the electronic device. When the child is pushed down, the built-in switch is operated to electrically connect the charging circuit and the power terminal, and charging is performed from the power terminal through the charging terminal of the electronic device.

Moreover, although it is not a horizontal charging apparatus, the flat charging apparatus which charges by installing an electronic device in the apparatus installation recessed part of the upper surface of a charging stand with the wide back surface facing downward is also proposed. In this conventional flat-type charging device, a power supply terminal recess / exit hole is provided in the device installation recess on the upper surface of the charging stand, and the power supply terminal provided corresponding to the power supply terminal extension / removal hole is normally hidden in the charging stand. When the electronic device is installed in the device installation recess, the power supply terminal recess is projected onto the device installation recess. The pusher retracting hole is normally provided with a pusher that protrudes above the device installation recess and descends when the electronic device is installed in the device installation recess. The presser has an electronic device in the device installation recess. When installed and lowered, the cam rotates in the charging stand and the horizontal rotating shaft rotates, and the cam causes the power terminal to protrude from the power terminal retracting hole onto the device installation recess, and this protruding power terminal is the electronic device. Charging by touching the charging terminal It has a structure to do.

Both ends of the bearing are rotatably supported by recesses at the upper end of the bearing bracket 11 erected from the bottom plate 2. The hook arm 9 is biased by a spring 12 wound around the shaft 10 so that the hook 8 falls in the protruding direction and temporarily holds the electronic device 4.

  On one side in the longitudinal direction of the bottom surface of the device installation recess 3, a presser retracting hole 14 is provided that allows the presser 13 that is pushed down by the installation of the electronic device 4 and protrudes outward by the removal of the electronic device 4 to protrude and retract. Yes. Further, the other side of the bottom surface of the device installation recess 3 in the longitudinal direction is usually immersed in the charging base 1 and placed on the surface of the device installation recess 3 by horizontally placing the electronic device 4 in the device installation recess 3. A pair of power terminal protruding and retracting holes 16 are provided for projecting and projecting a pair of power terminals 15 that protrude and contact a pair of charging terminals (not shown) of the electronic device 4. The power terminal 15 is formed by folding a conductive elastic wire into a projecting shape.

  On the bottom plate 2 of the charging stand 1, a seesaw arm 17 made of an insulating resin whose opposite ends move in the vertical direction is arranged in a state in which the charging stand 1 faces in the longitudinal direction. The seesaw arm 17 has a length corresponding to the pusher 13 at one end side 17 a and a length corresponding to the power supply terminal 15 at the other end side 17 b, and is arranged in a state in which the charging stand 1 is directed in the longitudinal direction. The seesaw arm 17 has a shaft 18 projecting horizontally in the middle of its longitudinal direction. Both ends of these shafts 18 are rotatably supported so that a seesaw motion can be performed in a recess at the upper end of a bearing bracket 19 erected from the bottom plate 2.

In the standby state, even if the pressing element 13 is pushed by hand and the power terminal 15 protrudes onto the device installation recess 3 of the charging stand 1, the pressing element 13 and the power terminal 15 are separated from each other. The power supply terminal 15 is not contacted, and low temperature burns can be avoided in this respect. In particular, since the operation is performed by the seesaw arm 17 even when the presser 13 and the power supply terminal 15 are separated from each other, the operation of the presser 13 and the power supply terminal 15 is easily performed by setting the length of the seesaw arm 17. be able to. Further, according to the seesaw arm 17, the structure is simpler than that provided with cams at both ends of the rotating shaft, and the structure can be implemented at low cost.
