Description

  The present invention relates to a charging system, a charger, a charging target device, and a charging method.

  In recent years, highly functional electronic devices have been used as portable terminals. These electronic devices include a secondary battery. In order to charge the secondary battery, a charging system for charging the secondary battery is used by contact between a power receiving terminal provided in the electronic device to be charged (device to be charged) and a charging terminal provided in the charger. .

  In the charger described in Patent Document 1, the power receiving terminal of the electronic device is mounted facing the opening of the charger so that the user pushes the protruding portion of the actuator provided in the charger. With this attachment, the charging terminal of the charger protrudes. The protruding charging terminal contacts the power receiving terminal of the electronic device.

  The charging device described in Patent Literature 2 includes an attachment detection unit that detects that a portable device is attached. The two rotating pieces constituting the mounting detection unit are independently supported. The power feeding terminal protrudes from the charging device by the rotation of the rotating piece. Due to the protrusion of the power feeding terminal, the power feeding terminal comes into contact with the power receiving terminal of the mounted portable device. Patent Document 2 describes a technique in which a power supply voltage is applied to a power feeding terminal of a charging device and a power receiving terminal of a portable device as the rotating piece rotates.

  In the charger described in Patent Document 1, the charging terminal of the charger protrudes when the protruding portion of the actuator is pushed. Therefore, even if the device to be charged is attached to the charger in the wrong direction, the charging operation to the portable device continues. The charging target device being attached to the charger in the wrong direction means that the power receiving terminal of the charging target device and the charging terminal of the charger are not attached to each other. That is, the charger described in Patent Document 1 cannot prevent a short circuit at the charging terminal when the charging target device is attached to the charger in the wrong direction.

  The charging device described in Patent Literature 2 can prevent a short circuit in a state where the charging target device is not attached. However, the charging operation continues even if the device to be charged is attached to the charger in the wrong direction. That is, the charging device described in Patent Document 2 cannot prevent a short circuit at the charging terminal when the charging target device is attached to the charger in the wrong direction. Moreover, the technique in which a power supply voltage is applied with rotation of a rotating piece presupposes that a charge object apparatus is mounted | worn with a charger in the right direction. That is, it is not considered that the charging target device is attached to the charger in the wrong direction. That the device to be charged is attached to the charger in the correct direction means that the device to be charged is attached in a direction in which the power receiving terminal of the device to be charged and the charging terminal of the charger are in contact.

  The present invention has been made in view of the above, and provides a charging system, a charger, a charging target device, and a charging method capable of preventing a short circuit of the charger even when the charging target device is attached to the charger in a wrong direction.

(Embodiment 1)
Embodiment 1 of the present invention will be described with reference to the drawings. As shown in FIG. 1, the charging system 1 includes a charging target device 2 and a charger 3. The charging target device 2 includes power receiving terminals 21 and 22 that are arranged so as to be exposed to the inside of the device from the outer wall surface of the housing. Here, the outer wall surface of the housing provided with the power receiving terminals 21 and 22 is the outer wall surface 23, and the other outer wall surface is the outer wall surface 24. Further, the power receiving terminals 21 and 22 are in contact with end portions 35 and 36 of charging terminals 33 and 34 which will be described later. The device 2 to be charged is charged by this contact.

  The charger 3 includes a mounting portion 31 for mounting the charging target device 2 on the upper surface, a side wall 32 protruding in the upper surface direction, and charging terminals 33 and 34. The side wall 32 accommodates the charging terminals 33 and 34. Further, the end portions 35 and 36 of the charging terminals 33 and 34 protrude from a slit 37 provided on the side wall 32. The end portions 35 and 36 of the charging terminals 33 and 34 are in contact with the power receiving terminals 21 and 22 of the charging target device 2. The device 2 to be charged is charged by this contact. Further, the charger 3 includes a charging circuit 38 connected to the charging terminals 33 and 34 and a stop unit 39 for stopping the power supply of the charging circuit 38 (FIG. 2).

  The device 2 to be charged is attached to the charger 3 by the user. When the charging target device 2 is attached to the charger 3 in an incorrect direction (hereinafter referred to as a direction in contact with the outer wall surface 24), the end portions 35 and 36 of the charging terminals 33 and 34 are outside the charging target device 2. It is pressed by the contact of the wall surface 24. By this pressing, the end portions 35 and 36 of the charging terminals 33 and 34 are retracted to the inside of the side wall 32. When the end portions 35 and 36 of the charging terminals 33 and 34 are retracted to the inside of the side wall 32, the stopping means 39 is operated by the movement of the charging terminals 33 and 34. The stop means 39 stops the power supply of the charging circuit 38. By stopping the power supply, the charging system 1 of the present embodiment can prevent a short circuit of the charger 3 (FIG. 3).

  Further, even when the casing of the charging target device 2 is decorated with a conductive seal or the like, the end portions 35 and 36 of the charging terminals 33 and 34 recede to the inside of the side wall 32. The charging system 1 can prevent a short circuit of the charger 3.

  On the other hand, when the charging target device 2 is attached to the charger 3 in the correct direction, the power receiving terminals 21 and 22 of the charging target device 2 come into contact with the end portions 35 and 36 of the charging terminals 33 and 34. Since the power receiving terminals 21 and 22 are disposed closer to the inside of the device than the outer wall surface 23 of the charging target device 2, the pressing due to this contact is smaller than when the outer wall surface 24 of the charging target device 2 is in contact. Therefore, the end portions 35 and 36 of the charging terminals 33 and 34 do not retract to the inside of the side wall 32. In this case, the stopping means 39 does not operate due to the movement of the charging terminals 33 and 34. Therefore, the charge object apparatus 2 is charged (FIG. 3).

  Specific configurations of the charging target device 2 and the charger 3 will be described.

  The power receiving terminals 21 and 22 of the charging target device 2 are disposed so as to be exposed to the inside of the device from the outer wall surface 23 of the casing of the charging target device 2 (FIG. 4). That is, the power receiving terminals 21 and 22 are located on the device inner side of the charging target device 2 from the outer wall surfaces 23 and 24 of the charging target device 2. The power receiving terminals 21 and 22 are connected to a power receiving circuit (not shown). The power receiving terminals 21 and 22 are in contact with the end portions 35 and 36 of the charging terminals 33 and 34 when the device 2 to be charged is attached to the charger 3 in the correct direction.

  As shown in FIG. 5, the charging terminals 33 and 34 of the charger 3 have a “U” shape. End portions 35 and 36 of the charging terminals 33 and 34 protrude from a slit 37 provided on the side wall 32 of the charger 3. The end portions 35 and 36 of the charging terminals 33 and 34 bent in a V shape come into contact with the power receiving terminals 21 and 22 of the charging target device 2 at the V-shaped tip portions. The other end of the charging terminals 33 and 34 forms a torsion spring. Further, the other ends of the charging terminals 33 and 34 are connected to the charging circuit 38. The coil portion of the torsion spring is supported by the support member 41. Therefore, when the end portions 35 and 36 of the charging terminals 33 and 34 are pressed toward the side wall 32, the charging terminals 33 and 34 bend inside the side wall 32.

  When the charging target device 2 is attached to the charger 3 in the wrong direction, the end portions 35 and 36 of the charging terminals 33 and 34 are pressed by the contact of the outer wall surface 24 of the charging target device 2. And the outer wall surface 24 of the charge object apparatus 2 will be in the state which block | closes the slit 37 of the side wall 32 of the charger 3. FIG. As a result, the end portions 35 and 36 of the charging terminals 33 and 34 are retracted to the inside of the side wall 32. Since the other ends of the charging terminals 33 and 34 form a torsion spring, the charging terminals 33 and 34 bend. Due to this bending, part of the charging terminals 33 and 34 (for example, bent portions of the charging terminals 33 and 34) 42 and 43 retreat inside the side wall 32 (FIG. 6A).

  On the other hand, when the charging target device 2 is attached to the charger 3 in the correct direction, the end portions 35 and 36 of the charging terminals 33 and 34 come into contact with the power receiving terminals 21 and 22 of the charging target device 2. Since the power receiving terminals 21 and 22 are located on the device inner side of the charging target device 2 from the outer wall surface 23 of the charging target device 2, the power receiving terminals 21 and 22 are in a state of closing the slit 37 on the side wall 32 of the charger 3. Don't be. As a result, the end portions 35 and 36 of the charging terminals 33 and 34 do not retreat to the inside of the side wall 32. That is, as illustrated in FIG. 6B, the portions 42 and 43 of the charging terminals 33 and 34 are not retracted as much as in the case of pressing by the outer wall surface 24 of the charging target device 2.

  The operation of the stopping means 39 is selected based on the difference in position where the portions 42 and 43 of the charging terminals 33 and 34 are retracted.

  The stopping means 39 of the charger 3 includes a semiconductor laser transmitter 44 and a light receiving sensor 46 corresponding to the laser beam 45 transmitted by the semiconductor laser transmitter 44. The light receiving sensor 46 receives the laser beam 45 when the charger 2 is not attached to the charger 3 (FIG. 7A). The light receiving sensor 46 transmits a signal to the charging circuit 38 when the laser light 45 is not received.

  The semiconductor laser transmitter 44 and the light receiving sensor 46 are arranged so that a part 42 of the retracted charging terminal 33 shields the laser beam 45 when the end portion 35 of the charging terminal 33 is retracted to the inside of the side wall 32. Is done. Hereinafter, when the end portions 35 and 36 of the charging terminals 33 and 34 are retracted to the inside of the side wall 32, a position where the parts 42 and 43 of the retracted charging terminals 33 and 34 reach is a predetermined position 100. . That is, the semiconductor laser transmitter 44 and the light receiving sensor 46 are arranged so that the light receiving sensor 46 does not receive the laser light 45 when the part 42 of the charging terminal 33 reaches the predetermined position 100 (FIG. 7B). )).

  As described above, when the end portions 35 and 36 of the charging terminals 33 and 34 are pressed by the contact of the outer wall surface 24 of the charging target device 2, the end portions 35 and 36 of the charging terminals 33 and 34 are located inside the side wall 32. Retreat until. Thereby, the part 42 of the charging terminal 33 reaches the predetermined position 100, and the part 42 of the charging terminal 33 shields the laser beam 45. The light receiving sensor 46 that has detected that the laser light 45 is shielded transmits a signal to the charging circuit 38. Upon receiving the signal from the light receiving sensor 46, the charging circuit 38 stops the power supply.

  On the other hand, when the end portions 35 and 36 of the charging terminals 33 and 34 are pressed against the power receiving terminals 21 and 22 of the charging target device 2, the pressing is smaller than when the outer wall surface 24 of the charging target device 2 is in contact. Therefore, the part 42 of the charging terminal 33 does not reach the predetermined position 100. Therefore, the part 42 of the charging terminal 33 does not shield the laser beam 45. Therefore, the charge object apparatus 2 is charged.

  According to the above configuration, when the charging target device 2 is attached to the charger 3 in the wrong direction, a short circuit of the charger 3 can be prevented.

  In the present embodiment, a mobile phone is illustrated as the charging target device 2, but the present invention is not limited to this. The present invention can be applied to all types of devices that require charging, such as notebook personal computers, tablet personal computers, PDAs (Personal Data Assistants), game machines, and electronic dictionaries. Moreover, the stop means 39 may be arrange | positioned in any of the charge terminals 33 and 34. FIG. The stop means 39 can be disposed on both the charging terminals 33 and 34. The same applies to the following embodiments.

(Embodiment 2)
A second embodiment of the present invention will be described with reference to the drawings. Here, the stop means 39 of the charger 3 will be described. Other configurations are the same as those in the first embodiment.

  The charger 3 includes a stop means 39 between the charging terminal 33 and the charging circuit 38. Specifically, the stop means 39 is a normally-on button type switch 49 (FIG. 8). The button type switch 49 is electrically turned on when the button portion 50 is not depressed, and is electrically turned off when the button portion 50 is depressed. The button part 50 of the button type switch 49 is arranged at a predetermined position 100 in the charging terminal 33.

  When the device 2 to be charged is attached to the charger 3 in the wrong direction, the end portions 35 and 36 of the charging terminals 33 and 34 are retracted to the inside of the side wall 32 as in the first embodiment. Then, the portions 42 and 43 of the charging terminals 33 and 34 reach a predetermined position 100. The part 42 of the charging terminal 33 that has reached the predetermined position 100 presses the button part 50 of the button-type switch 49 (FIG. 9A). The button type switch 49 is turned off electrically. Thereby, since the electric power supply from the charging circuit 38 stops, the charging system 1 of this embodiment can prevent the short circuit of the charger 3.

  When the charging target device 2 is attached to the charger 3 in the correct direction, the end portions 35 and 36 of the charging terminals 33 and 34 come into contact with the power receiving terminals 21 and 22 of the charging target device 2. Since the power receiving terminals 21 and 22 are located on the device inner side of the charging target device 2 from the outer wall surface 23 of the charging target device 2, the end portions 35 and 36 of the charging terminals 33 and 34 recede to the inside of the side wall 32. do not do. Therefore, a part 42 of the charging terminal 33 does not reach the predetermined position 100 (FIG. 9B). Therefore, the button portion 50 of the button type switch 49 is not pressed. Therefore, the charge object apparatus 2 is charged.

  Further, the charging terminal 33 may constitute a part of the stopping means 39. For example, the charging terminal 33 includes an insulator in a part 42 thereof. A contact is provided between the charging circuit 38 and the charging terminal 33. This contact is disposed at a predetermined position 100. The charging terminal 33 is bent by the outer wall surface 24 of the charging target device 2 pressing the end portion 35 of the charging terminal 33. When the charging terminal 33 is bent, the insulator attached to the part 42 of the charging terminal 33 reaches the predetermined position 100. Then, the insulator attached to the part 42 of the charging terminal 33 cuts off the contact. Thereby, the power supply from the charging circuit 38 is stopped. According to this configuration, the number of parts of the charger 3 can be reduced.

(Embodiment 3)
Embodiment 3 of the present invention will be described with reference to the drawings. In the present embodiment, the charger 3 includes a detection unit 60 (not shown) and a protruding mechanism 61 (not shown). The detection unit 60 detects that the charging target device 2 is attached to the charger 3. Further, the protrusion mechanism 61 causes the end portions 35 and 36 of the charging terminals 33 and 34 to protrude from the slit 37 when the detection unit 60 detects the attachment of the charging target device 2. Here, these points will be described. Other configurations are the same as those in the second embodiment.

  The charger 3 includes a mounting portion 31 for mounting the charging target device 2 on the upper surface, and a side wall 32 protruding in the upper surface direction. A slit 37 is provided in the side wall 32. The side wall 32 accommodates the charging terminals 33 and 34. The end portions 35 and 36 of the charging terminals 33 and 34 that have been housed protrude from the slit 37. Furthermore, as shown in FIG. 10, the button hole 62 is provided on the opposite side of the side wall 32 of the mounting portion 31. A part of a button 63 of the detection unit 60 described later protrudes from the button hole 62.

  FIG. 11 shows an outline of a BB cross section in FIG. The mounting portion 31 includes a protrusion 64 that extends toward the lower surface of the charger 3 on the lower surface. Moreover, the protrusion part 64 is provided with the penetration part 67 (not shown) through which the connection part 74 mentioned later passes.

  The detection unit 60 includes a button 63 and a button rib 69. A part of the button 63 protrudes from the button hole 62 to the mounting portion 31. A part of the button 63 protruding from the mounting portion 31 is pressed by mounting the charging target device 2. The button rib 69 is integrally provided on the surface (the lower surface of the button 63) that faces the surface of the button 63 that is pressed by the charging target device 2. Therefore, when the button 63 is pressed down due to the mounting of the charging target device 2, the button rib 69 integrated with the button 63 is also pressed down. In addition, the button rib 69 includes an inclined surface 70 that is inclined in the pressing direction. The inclined surface 70 is in contact with a concave inner wall surface of a button-side holder 72 described later.

  The protrusion mechanism 61 includes a button side holder 72 and a terminal side holder 73 coupled to the button side holder 72. The button side holder 72 is formed in a concave shape. The button side holder 72 is disposed such that the concave inner wall surface is in contact with the inclined surface 70 of the button rib. Since the button side holder 72 is in contact with the inclined surface 70 of the button rib at its concave inner wall surface, the button side holder 72 moves in the direction of the button 63 along the inclined surface 70 of the button rib when the button rib 69 is pushed down. Moving. Further, the terminal side holder 73 coupled to the button side holder 72 also moves in the direction of the button 63. The terminal side holder 73 is coupled to the button side holder via the connecting portion 74. The connecting portion 74 passes through the through portion 67 of the projecting portion 64 and connects the button side holder 72 and the terminal side holder 73. The terminal side holder 73 includes charging terminals 33 and 34, a support member 41, and a button type switch 49. Further, the terminal side holder 73 is arranged so that the end portions 35 and 36 of the charging terminals 33 and 34 do not protrude from the slit 37 when the charging target device 2 is not mounted on the side wall 32 side opposite to the button 63. Be placed.

  When the charging target device 2 is attached to the charger 3, the button 63 is pressed. Thereby, the button rib 69 integrated with the button 63 is also pushed down. Since the inclined surface 70 of the button rib is in contact with the inner wall surface of the button side holder 72, the button side holder 72 and the terminal side holder 73 move in the direction of the button 63 when the button rib 69 is pushed down. As a result, the end portions 35 and 36 of the charging terminals 33 and 34 provided in the terminal-side holder 73 protrude from the slit 37 of the side wall 32 (FIG. 11B).

  A coil spring 75 may be provided between the protruding portion 64 of the mounting portion 31 and the terminal side holder 73. The coil spring 75 has a connecting portion 74 passing through the diameter thereof, one end being a projecting portion 64 of the mounting portion 31, and the other end being fixed to the terminal side holder 73 (FIG. 11B). When the terminal-side holder 73 moves due to the attachment of the charging target device 2, the coil spring 75 contracts. When the user removes the charging target device 2 from the charger 3, the button-side holder 72, the terminal-side holder 73, and the detection unit 60 are restored to the state before the charging target device 2 is mounted by the elasticity of the coil spring 75. To do.

  When the charging target device 2 is attached to the charger 3 in the wrong direction by the user, the protruding mechanism 61 operates. However, since the outer wall surface 24 of the charging target device 2 closes the slit 37, the end portions 35 and 36 of the charging terminals 33 and 34 cannot contact the outer wall surface 24 and protrude from the slit 37. As a result, the charging terminals 33 and 34 are bent in the inner direction of the side wall 32. As a result, as shown in FIG. 12, a part 42 of the charging terminal 33 reaches a predetermined position 100. The part 42 of the charging terminal 33 presses the button part 50 of the button type switch. Since the button type switch 49 is electrically turned off, the power supply by the charging circuit 38 is stopped. Therefore, the charging system 1 of the present embodiment can prevent a short circuit of the charger 3.

  When the device 2 to be charged is attached to the charger 3 in the correct direction, the protruding mechanism 61 operates. Since the power receiving terminals 21 and 22 are located on the device inner side of the charging target device 2 from the outer wall surface 23 of the charging target device 2, the end portions 35 and 36 of the charging terminals 33 and 34 protrude from the slit 37 of the side wall 32. . Then, the end portions 35 and 36 of the charging terminals 33 and 34 are in contact with the power receiving terminals 21 and 22 of the charging target device 2. Since the press by this contact is small compared with the case where the outer wall surface 24 of the charge object apparatus 2 contacts, the bending of the charge terminals 33 and 34 is also small. Therefore, the part 42 of the charging terminal 33 does not reach the predetermined position 100. Since the button type switch 49 remains electrically on, the charging target device 2 is charged.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and applications are possible.

  A part or all of the above embodiment can be described as in the following supplementary notes, but is not limited to the following.
