Description

  The present invention relates to a charging base for a mobile device for charging a battery provided in a mobile device such as a mobile communication device or a PDA (Personal Digital Assistant).

  In general, mobile devices such as mobile phones such as mobile phones and PHS, cordless cordless handsets attached to PDAs or wired phones have built-in batteries for obtaining power necessary for transmission and reception, and charging bases. It is necessary to charge regularly.

  Conventionally, as a charging stand for such a portable device, for example, those shown in FIGS. 4 and 5 exist. This is because a desktop holder 3 in which an accommodation space 2 in which a mobile phone 1 as a portable device 1 can be mounted is formed on the upper surface, a substrate 4 disposed in the desktop holder 3, and the accommodation space 2 of the desktop holder 3. The power supply terminal 6 attached to the substrate 4 with solder or the like so that the charging terminal 5 of the mobile phone 1 can come into contact with the power supply connection plug 7 is connected to the substrate 4 with solder or the like. And a claw portion 10 that protrudes into the accommodation space 2 and engages with the engagement groove 9 of the mobile phone 1 provided on the opposite side of the desktop holder 3 from the power supply terminal 6. It has the composition which becomes.

  The desktop holder 3 is formed by integrally assembling an upper case 3a and a lower case 3b, and the claw portion 10 is pivotally supported so as to be rotatable around the pin 11 in the upper case 3a. The lock arm 12 is integrally formed at the distal end of the arm 12, and the lock arm 12 is urged in a counterclockwise direction around the pin 11 in FIG. The claw portion 10 protrudes from the small hole 14 of the upper case 3a by a required amount.

  On the other hand, the connection plug 7 has an AC metal terminal 15 connected to a power outlet (not shown), and an adapter cord 17 for an AC adapter 16 that converts an alternating current into a direct current of a predetermined voltage value. And is detachably connected to the connector 8 from an insertion hole 18 formed in the upper case 3a of the desktop holder 3.

  In addition, foot pieces 19 made of an elastic member such as rubber are attached to the four corners of the bottom surface of the lower case 3b of the desktop holder 3 with a double-sided tape or an adhesive. 3 is designed to stabilize itself and to prevent the surface of a desk or table from being damaged.

  4 and 5, reference numeral 20 denotes a rib projecting on the inner surface side of the accommodation space 2 in the upper case 3 a of the desktop holder 3, and when the cellular phone 1 is mounted in the accommodation space 2, The rib 20 is engaged with the groove portion 21.

  When charging the cellular phone 1, the connection plug 7 of the adapter cord 17 is connected to the connector 8 through the insertion hole 18 formed in the upper case 3 a of the desktop holder 3 and the AC metal terminal 15 of the AC adapter 16 is connected. When the mobile phone 1 is fitted in the accommodation space 2 of the upper case 3a of the desktop holder 3 in a state where it is connected to the power supply outlet, the charging terminal 5 of the mobile phone 1 contacts the power supply terminal 6, and The rib 20 is engaged with the groove portion 21 of the mobile phone 1 and the claw portion 10 protruding from the small hole 14 of the upper case 3 a by a required amount is once pushed into the small hole 14 against the urging force of the spring 13. Thus, the insertion of the mobile phone 1 into the accommodation space 2 is allowed, and when the mobile phone 1 is inserted to a predetermined position, the claw portion 10 is moved by the urging force of the spring 13 to the upper case 3. The small hole 14 again protrudes by a required amount and engages with the engaging groove 9 of the mobile phone 1 so that the mobile phone 1 cannot be easily removed from the accommodating space 2. In this state, the mobile phone 1 is built in the mobile phone 1. The battery is charged.

  After the charging is completed, when the mobile phone 1 is lifted with a slight force from the desktop holder 3, the claw portion 10 engaged with the engaging groove 9 of the mobile phone 1 resists the urging force of the spring 13. The cellular phone 1 is once pushed into the small hole 14, thereby allowing the cellular phone 1 to be detached from the accommodation space 2, and the cellular phone 1 is removed from the desktop holder 3.

  However, the conventional charging stand for portable devices as described above requires components such as the lock arm 12 and the spring 13 as a locking mechanism for fixing the cellular phone 1 when the cellular phone 1 is mounted on the desktop holder 3. As a result, the number of parts and assembly man-hours increased, leading to an increase in cost. Further, the area of the substrate 4 to which the power supply terminal 6 and the connector 8 are attached is increased, and when the connection plug 7 is connected to the connector 8, the connection plug 7 protrudes to the outside of the desktop holder 3. As a result, a large installation space is required, leaving room for improvement.

In order to cope with this problem, there is one in which the structure of the desktop holder is simplified and the cost is reduced by reducing the number of parts and the number of assembling steps (for example, see Patent Document 1).
JP 2003-51875 A

  However, the charging stand shown in FIG. 4 and FIG. 5 and the charging stand shown in Patent Document 1 have a structure in which the power feeding terminal 6 is always exposed in the accommodating space 2 when neither is used. When the user touches the exposed power supply terminal 6, there is a risk of electric shock, and when a metal member contacts the exposed power supply terminal 6, a short circuit may occur.

  4 and FIG. 5 and the charging stand shown in Patent Document 1 are both configured to hold the entire length of the mobile phone 1 with the desktop holder 3 for charging. The desktop holder 3 has a longer length than the mobile phone 1 and has a problem of being unsuitable for carrying because of its large shape.

  In view of such circumstances, the present invention can prevent electric shock and short circuit by accommodating the power feeding terminal in the holder when the mobile device is not charged, and can reduce the overall length of the holder to facilitate carrying. An object of the present invention is to provide a charging stand for portable devices that can improve convenience.

The present invention provides a charging stand for a portable device having a power feeding terminal that can be electrically connected to a charging terminal of the portable device in a holder to which the portable device can be mounted.
The holder is composed of two members that are slidably engaged with each other, and can be expanded and contracted, and an elastic body is provided in the holder to urge the two members close to each other in a direction that causes the entire length of the holder to contract. In a state where the two members slide toward each other due to the biasing force of the elastic body and the holder contracts, the power supply terminal is accommodated in one member, and the two members resist the biasing force of the elastic body. In a state where the members are slid in the direction of separating from each other and the holder is extended, the power feeding terminal protrudes from one member and is configured to be electrically connected to the charging terminal of the portable device attached to the holder. It is applied to the charging stand for portable devices which is a feature.

  In the portable device charging stand, the two members constituting the holder are provided with convex portions or concave portions that engage with concave portions or convex portions provided on the charging terminal side and the charging terminal side of the portable device, respectively. It is preferable to have the portable device in order to securely attach the portable device to the holder.

  According to the charging stand for portable devices of the present invention, when the portable device is not charged, it is possible to prevent an electric shock or a short circuit by accommodating the power feeding terminal in the holder, and to shorten the overall length of the holder so that it can be easily carried. In addition, an excellent effect of improving convenience can be achieved.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  1 to 3 show an example of an embodiment of the present invention. In the drawings, the parts denoted by the same reference numerals as those in FIGS. 4 and 5 represent the same thing, and the holders 30 are slidably engaged with each other. The first holder member 30a and the second holder member 30b, which are two members to be combined, can be expanded and contracted, and the first holder member 30a and the second holder member are disposed in the first holder member 30a of the holder 30. An elastic body 31 such as a tension spring that urges 30b close to each other and urges the entire length of the holder 30 in a contraction direction is provided, and the first holder member 30a and the second holder member 30b are urged by the urging force of the elastic body 31. When the holder 30 is contracted by sliding toward each other, the power supply terminal 6 is accommodated in the second holder member 30b, and the first holder member 30a and the second holder 30a are resisted against the urging force of the elastic body 31. When the holder 30 is extended by sliding the member 30b away from each other, the power feeding terminal 6 protrudes from the second holder member 30b and is electrically connected to the charging terminal 5 of the mobile phone 1 attached to the holder 30. It is comprised so that it may be connected to.

  The first holder member 30a is constituted by a hollow member having one end opened, and is slidable so that a part of the second holder member 30b enters therein. The first holder member 30a An elastic body 31 such as a tension spring is provided inside and is biased toward the side where the second holder member 30b is drawn.

  Further, a substrate 4 is disposed inside the second holder member 30b, and the substrate 4 projects outward from a terminal opening 32 formed in the second holder member 30b to charge the mobile phone 1. The power supply terminal 6 that can be brought into contact with the terminal 5 and the connector 8 for inserting and connecting the power supply connection plug 7 through the insertion hole 33 are attached with solder or the like, while the second of the first holder member 30a is attached. At the end on the holder member 30b side, a pressing protrusion 35 is formed which can be inserted into a pressing hole 34 drilled at a position below the terminal opening 32 of the second holder member 30b. When the 30 is contracted, the pressing protrusion 35 of the first holder member 30a enters the pressing hole 34 of the second holder member 30b and presses the power feeding terminal 6, so that the power feeding terminal 6 Terminal opening of the two holder member 30b It is to be accommodated in the 2.

  Further, the support receiving portion 36 for the cellular phone 1 protruding from the upper surface of the end portion of the first holder member 30a is engaged as a recess provided on the opposite side to the charging terminal 5 of the cellular phone 1. A claw portion 37 that engages with the groove 9 is projected, and the support receiving portion 38 for the cellular phone 1 that is projected on both upper surfaces of the end portion of the second holder member 30b is connected to the charging terminal 5 of the cellular phone 1. A rib 39 is provided so as to be engaged with the groove portion 21 as a concave portion provided on the side.

  As shown in FIG. 2, the end of the first holder member 30a abuts against the end of the second holder member 30b when the holder 30 is contracted to restrict further movement toward the contraction side. The stopper 40 is formed.

  Next, the operation of the illustrated example will be described.

  When the mobile phone 1 is not charged, as shown in FIGS. 1A and 2A, the first holder member 30a and the second holder member 30b are moved closer to each other by the urging force of the elastic body 31. The holder 30 is slid and held in a contracted state, and the pressing protrusion 35 enters the pressing hole 34 and presses the power supply terminal 6, so that the power supply terminal 6 is a terminal opening 32 of the second holder member 30 b. It is housed inside and is not exposed to the outside.

  As a result, at the time of non-charging, it is possible to surely prevent a problem that the user touches the power supply terminal 6 to get an electric shock, or a metal member contacts the power supply terminal 6 to cause a short circuit.

  Further, when not charging, the holder 30 is shorter than the length of the mobile phone 1 and is miniaturized, so that it is easy to carry.

  On the other hand, when charging the mobile phone 1, the connection plug 7 of the adapter cord 17 is connected to the connector 8 through the insertion hole 33 formed in the second holder member 30 b of the holder 30 and the AC metal terminal 15 of the AC adapter 16 is connected. Are connected to a power supply outlet (not shown), as shown in FIGS. 1B and 2B, the first holder member 30a and the second holder are resisted against the biasing force of the elastic body 31. When the holder 30 is extended so as to be slightly longer than the entire length of the mobile phone 1 by sliding the member 30b away from each other, the pressing protrusion 35 is pulled out from the pressing hole 34, and power is supplied by the pressing protrusion 35. Since the pressing state of the terminal 6 is released and the power supply terminal 6 protrudes from the terminal opening 32 of the second holder member 30b by its own spring force, the first holder member 30 is in this state. When the mobile phone 1 is set between the second holder member 30b and the hand is released, the power supply terminal 6 contacts and is electrically connected to the charging terminal 5 of the mobile phone 1, and the mobile phone 1 is charged. Is done.

  At this time, the rib 39 of the second holder member 30 b is engaged with the groove portion 21 of the mobile phone 1, and the claw portion 37 of the first holder member 30 a is engaged with the engagement groove 9 of the mobile phone 1. In addition, since the first holder member 30 a and the second holder member 30 b sandwich the mobile phone 1 by the urging force of the elastic body 31, the mobile phone 1 is securely attached to the holder 30. Will be held.

  Further, in the illustrated example, the claw portion 37 is formed integrally with the first holder member 30a because the holder 30 is extended to be slightly longer than the entire length of the mobile phone 1 and the mobile phone 1 is set. In this case, as a locking mechanism for fixing the cellular phone 1 when the cellular phone 1 is mounted on the desktop holder 3, like the claw portion 10 of the conventional charging stand shown in FIGS. There is no need to provide parts such as the lock arm 12 and the spring 13, and it is not necessary to form elastically deformable parts like the claw portion (not shown) of the conventional charging base shown in Patent Document 1, and the number of parts In addition to being able to reduce and reduce the number of assembly steps, it is possible to reduce costs by simplifying the structure. Note that the claw portion 37 may have a lock mechanism as shown in FIGS.

  In the illustrated example, the first holder member 30a and the second holder member 30b constituting the holder 30 are respectively provided with claw portions 37 and ribs 39 as convex portions, and are carried in correspondence with these. An engaging groove 9 as a recess is formed on the side opposite to the charging terminal 5 of the telephone 1 and a groove 21 as a recess is formed on the charging terminal 5 side of the mobile telephone 1. It is also possible to form a concave portion on the side and a convex portion on the mobile phone 1 side.

  Thus, when the mobile phone 1 is not charged, housing the power supply terminal 6 in the holder 30 can prevent electric shock and short circuit, and the overall length of the holder 30 can be shortened to facilitate carrying and improve convenience. Can do.

  In addition, the charging stand for portable devices of the present invention is not limited to the above illustrated example, and can be used as a charging stand for various portable devices other than the mobile phone, and the shape of the holder can be variously changed. It goes without saying that various changes can be made without departing from the scope of the present invention.
