Description

  The present invention relates to a terminal including a power receiving electrode having a shutter on a side surface of a casing included in the terminal, and particularly to a technique for preventing induction of electric power in the power receiving electrode.

  Japanese Patent Application Laid-Open No. 2004-133826 includes a placement terminal that includes a power feeding unit that converts power and a battery unit that stores power, and a mobile phone that is placed on the placement terminal and receives power. When a mobile phone is placed on a placement terminal, there is a terminal that disconnects the battery unit from the power supply unit and locks it to the mobile phone, and supplies power from the battery unit to the mobile phone.

JP 2011-155608 A

  However, this terminal can receive power from the battery unit only when the mobile phone and the battery unit are locked at one place when the mobile phone receives power from the battery unit. For this reason, when power is supplied from an AC power source, the position of the mobile phone is fixed, and power cannot be supplied from the AC power source by changing the placement position. In addition, it has been difficult to use a mobile phone in a vertical or horizontal position.

  Accordingly, an object of the present invention is to receive power at a plurality of placement positions without fixing the placement position of the power receiving terminal with respect to the charging stand at one place. An object of the present invention is to provide a power receiving terminal that can prevent this.

In order to solve the above-described problems, the present invention has a structure of a power receiving terminal that receives power from a charging stand on which the self power receiving terminal is placed and charges a secondary battery included in the operation of the self power receiving terminal or the self power receiving terminal. There,
A plurality of power receiving electrodes formed on a surface of a casing of the self-power receiving terminal facing a surface on which the power feeding electrode of the charging stand is formed; a plurality of shutters covering each surface of the power receiving electrode; A rotating shaft that holds each of the power receiving electrodes rotatably, and a plurality of closing springs that act in a direction to close the power receiving electrode with the shutter, the shutter supporting the rotating shaft and a cover portion that covers the power receiving electrode. And a lever portion that opens and closes the shutter, and the lever portion pushes the lever portion formed at a predetermined portion of the charging base when the self-power receiving terminal is placed on the charging base. It is formed in the position which contacts the projection part for this.

  According to the present invention, when mounting on a charging base on which a plurality of power feeding electrodes or rail-shaped power feeding electrodes are formed, only the shutter of the portion facing the protrusion formed on the charging base is opened. Since the shutter remains closed, there is an advantage that there is less risk of a short circuit caused by a receiving electrode other than the receiving electrode that is receiving power.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing a configuration of an embodiment according to the present invention, and is a perspective view of a state where a power receiving terminal is placed on a charging stand.

  Reference numeral 1 denotes a charging stand, and 11 denotes a power receiving terminal. When the power receiving terminal 11 is placed on the charging stand 1 and the power receiving terminal 11 receives power from the charging stand 1, the operation of the power receiving terminal 11 or the secondary battery of the power receiving terminal 11 is charged. Details will be described below.

  FIG. 2 is a diagram showing a configuration of an embodiment according to the present invention, and is a perspective view of the power receiving terminal 11 as seen from the power receiving electrode side. Reference numeral 12 denotes a bottom surface of the power receiving terminal 11.

  The bottom surface 12 of the power receiving terminal 11 has a shutter 21 on the bottom surface and a ground lane 22 on the bottom surface.

  A plurality of the shutters 21 on the bottom surface are provided on the bottom surface 12, and a power receiving electrode 41 (described later) for receiving power from the charging stand 1 is incorporated therein. The shutter 21 on the bottom surface protects the power receiving electrode 41 and the power receiving electrode 41 is exposed only when the shutter 21 on the bottom surface is opened. In addition, the shutter 21 on the bottom surface has a strength that does not deform due to bending due to its own weight.

  The ground lane 22 is provided as one electrode on the bottom surface 12 of the power receiving terminal 11 and is exposed without protecting the shutter or the like in this embodiment. In addition, a shutter may be provided for the purpose of protection from dust or the like, and may be selected according to the installation location or application.

  Like the shutter 21 on the bottom surface 12 and the ground lane 22 on the bottom surface 12, the right side surface 13 of the power receiving terminal 11 has a right side shutter 23 and a right side ground lane 24. Further, the left side surface 14 has the same structure as the right side surface 13 (not shown).

  FIG. 3 is a perspective view showing the structure of the charging stand 1 according to an embodiment of the present invention. Reference numeral 2 denotes a placement unit for placing the power receiving terminal 11 on the charging stand 1. 3 is a power transmission electrode of the charging stand 1, 4 is a ground electrode, and 5 is a shutter release protrusion.

  FIG. 4A is a diagram illustrating a configuration of an embodiment according to the present invention, and a state immediately before the power receiving terminal 11 is placed on the charging base 1 with the bottom surface 12 facing the mounting portion 2 side of the charging base 1. FIG. FIG. 4B shows a cross section AA in FIG. FIG. 4C shows a detailed view of B in FIG. Reference numeral 31 denotes a bottom closing spring that applies a load in a direction in which the bottom shutter 21 closes, 32 denotes a rotating shaft of the bottom shutter 21, and 33 denotes a lever portion of the bottom shutter.

  As shown in the figure, when the power receiving terminal 11 is not placed on the charging stand 1, the shutter lever 33 on the bottom surface is in a closed state because a load is applied from the closing spring 31 on the bottom surface. The electrode 41 is covered with the shutter 21 and cannot be touched from the outside of the terminal. In the drawing in this embodiment, the closing spring 31 on the bottom surface is a torsion spring. However, if the lever portion 33 of the shutter 21 on the bottom surface is loaded and has flexibility, it is not necessary to be concerned with the shape of this drawing. Alternatively, for example, a load may be applied to the lever portion 33 of the shutter 21 on the bottom surface with a foam material having a reaction force such as a leaf spring or a sponge. Here, it is only necessary to apply a load so that the shutter 21 on the bottom surface is closed when the power receiving terminal 11 is not placed on the charging stand 1.

  Although the ground lane 22 is flush with or protrudes from the surface of the bottom surface 12 of the charging base 11, the ground lane 22 is in a state immediately before the power receiving terminal 11 is placed on the charging base 1, so that it contacts the ground electrode 4 of the charging base 1. Not done.

  FIG. 5A is a diagram illustrating a configuration of an embodiment according to the present invention, and the power receiving terminal 11 is placed on the charging base 1 in a direction facing the mounting portion 2 of the charging base 1. It is a perspective view which shows a state. FIG.5 (b) shows the cross section CC in FIG.5 (a). FIG. 5 (c) shows a detailed view of D in FIG. 5 (b).

  When the power receiving terminal 11 is placed on the placing portion 2 of the charging stand 1, the shutter release protrusion 5 of the charging stand 1 pushes up the lever portion 33 of the bottom shutter of the power receiving terminal 11, and the bottom shutter 21 rotates. The power receiving electrode 41 is exposed by rotating and opening with the shaft 32 as a fulcrum.

  At this time, since the power transmitting electrode 3 of the charging base 1 and the power receiving electrode 41 of the power receiving terminal 11 are in contact, and the ground electrode 4 of the charging base 1 and the ground lane 22 on the bottom surface of the power receiving terminal 11 are in contact, the power receiving terminal 11 is charged. Electric power can be received from the stand 1.

  At this time, the power receiving electrode provided on the right side and the power receiving electrode (not shown) provided on the left side are charged with power similarly to the power receiving electrode 41 on the bottom side, but the right side shutter 23 and the left side shutter (see FIG. (Not shown) covers the powered receiving electrode.

  When the operator removes the power receiving terminal 11 from the charging stand 1, there is a very high possibility that the operator will suddenly touch the right side surface 13 or the left side surface 14 of the power receiving terminal 11, but even in that case, it can be protected from the risk of electric shock. .

  FIG. 6 is a diagram illustrating a configuration of an embodiment according to the present invention, and is a diagram in which the center of the power receiving terminal 11 and the center of the charging stand 1 are not aligned and are placed in a laterally shifted state. That is, as shown in FIG. 2, by having a plurality of shutters 21 on the bottom surface 12 of the power receiving terminal 11 and a built-in power receiving electrode 41, the power receiving terminal 11 is not placed without matching the center position of the charging stand 1. However, since the power receiving electrode 41 on the bottom surface 12 and the ground lane 22 on the bottom surface 12 are in contact with the power transmitting electrode 3 and the ground electrode 4, the mounting position of the power receiving terminal 11 is not fixed at one place, and the degree of freedom of the mounting position. Becomes larger. Therefore, mounting can be performed easily.

  FIG. 7A is a diagram showing a configuration of an embodiment according to the present invention, and shows a state in which the right side surface 13 of the power receiving terminal 11 is placed toward the placement unit 2 side of the charging stand 1.

  That is, as shown in FIG. 2, the right side shutter 23, the right side ground lane 24, and the built-in power receiving electrode are also provided on the right side 13 so that the power receiving terminal 11 can be placed in such a direction. The power receiving state is entered. Similarly, even when the left side surface 14 of the power receiving terminal 11 is placed facing the charging base 1 as shown in FIG. 7B, the power receiving state can be set.

  Accordingly, when the direction in which the bottom surface 12 is placed toward the placement unit 2 side of the charging base 1 as shown in FIG. 2 is referred to as vertical placement, FIGS. 7A and 7B are horizontal placement. A power transmission / reception terminal that can be placed and placed horizontally can be realized.

  In the present embodiment, it is assumed that the bottom surface 12 is open in a lattice shape and the shutters 21 on the bottom surface are individually arranged, but this is not a limitation. You may make it provide the shutter by making the opening | mouth opened in the grid | lattice form of the bottom face 12 into one continuous opening | mouth. By doing so, when the power receiving terminal 11 is placed on the charging stand 1, power can be received at any position of one continuous mouth, and usability is improved.

  The bottom shutter 21 is provided with a function of locking the shutter when there is no projection. When the shutter release projection 5 and the bottom shutter 21 are not in contact with each other, the bottom shutter 21 is locked to thereby inadvertently release the shutter. May not be opened.
