Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings. Among the constituent elements having the same function, the same reference numerals are given to the elements having the same function, and the description thereof is omitted.

Fig. 1 is a diagram showing an example of a toy system according to an embodiment of the present invention. The toy system of the present invention comprises: device control apparatus 10,

dollies

20a, 20b, controller 17, and cartridge 18.

The

carriages

20a and 20b are one type of battery-driven devices, and are mobile devices that can travel automatically. These all have the same function. Hereinafter, one of these

carriages

20a, 20b will be referred to as a carriage 20 unless otherwise specified. The cart 20 includes: a storage battery, a camera for detecting the position under the image and wheels. The carriage 20 moves by the rotation of the wheels according to the position detected by the camera. The device control apparatus 10 controls the trolley 20 by radio. The controller 17 is an input device for acquiring an operation by a user, and is connected to the device control apparatus 10 via a cable.

The device control apparatus 10 has two recesses 32 for placing the dolly 20 for charging. The two recesses 32 are configured to be fitted into the carriage 20. Further, the device control apparatus 10 is connected to a power supply cable 19. The power cable 19 is connected to an AC adapter not shown. In addition, the device control apparatus 10 has a configuration for inserting and extracting a cartridge 18 in which software and the like are accommodated.

Fig. 2 is an exploded perspective view of the appliance control device 10. The device control apparatus 10 includes a housing constituted by an upper housing member 51, a lower housing member 52, and a foot 53. The upper case member 51, the lower case member 52, and the leg portion 53 are fixed to each other by fixing pins 54. The appliance control device 10 further includes: the card box connector 34, the display 36, the main board 56, the power connector 55, the carriage receiving portion 57, the power supply terminal 58, the metal plate 61, and the conductive pin 62. They are disposed within the housing. The cartridge connector 34 has the structure of the pluggable cartridge 18. The upper housing member 51 has two rounded rectangular openings 86.

Main board 56 is fixed in the housing, and power connector 55 is connected to the wiring on main board 56. Power cable 19 is connected to power connector 55, and power cable 19 is connected to an AC adapter not shown. The AC adapter supplies a power supply potential and a ground potential to the main board 56 via the power connector 55. The main board 56 is provided with the cartridge connector 34, the display 36, the power supply terminal 58, a processor and a memory, which are not shown.

The carriage receiving portion 57 has a concave portion corresponding to the shape of the lower portion of the carriage 20, and the concave portion has an inner peripheral surface and a bottom surface connected to the inner peripheral surface. A through hole is provided in the bottom surface, and the power supply terminal 58 protrudes from the bottom surface of the carriage receiving portion 57 through the through hole. The metal plate 61 and the upper case member 51 are disposed on the carriage receiving portion 57. The opening 86 of the upper case member 51 and the recessed portion of the carriage receiving portion 57 are disposed so as to overlap in plan view. The metal plate 61 is sandwiched between the carriage receiving portion 57 and the upper case member 51.

The metal plate 61 has a substantially rectangular opening 65. The opening 65 is disposed so as to overlap the opening 86 of the upper case member 51 and the recessed portion of the carriage receiving portion 57 in plan view. One end of the metal plate 61 is connected to the conductive pin 62, and the conductive pin 62 is connected to the wiring on the main substrate 56. The metal plate 61 is connected to the power connector 55 via its wiring and grounded. The metal plate 61 functions as a lightning rod.

The recess 32 is formed by an opening 86 provided in the upper case member 51, the inner peripheral surface and the bottom surface of the carriage receiving portion 57, and the power supply terminal 58. The carriage receiving portion 57 and the power supply terminal 58 provided in any one of the concave portions 32 have the same shape. Further, the metal plate 61 is disposed so as to surround the recess 32.

The configuration of the device control apparatus 10 will be further described. Fig. 3 is a plan view of the equipment control device 10 and the carriage 20, fig. 4 is a sectional view of the equipment control device 10 and the carriage 20 shown in fig. 3 taken along the IV-IV cut line, and fig. 5 is a sectional view of the equipment control device 10 and the carriage 20 shown in fig. 3 taken along the V-V cut line. The carriage 20 is fitted into the left recess 32 in fig. 3. Accordingly, fig. 5 shows a cross section of the carriage 20.

Fig. 4 and 5 show not only the cross section but also the surface of a member located opposite the cross section when viewed from the viewpoint, that is, a member located between the viewpoint and the surface where no shield is provided. Therefore, fig. 4 shows a shape of the upper portion of the carriage 20 as viewed from the side. For convenience of explanation, parts are not shown in fig. 4 and 5.

As shown in fig. 5, the cart 20 includes: a circuit board 72, a power receiving terminal 71 connected to the circuit board 72, a gear 73, a battery 74, a first cover member 76, a second cover member 77, and a third cover member 78. The cart 20 includes a tire, a motor, and a microcontroller, which are not shown. The first cover member 76, the second cover member 77, and the third cover member 78 constitute the exterior of the cart 20. When the cart 20 is fitted, the power receiving terminal 71 included in the cart 20 is inserted into the power supply terminal 58. In this case, a current is supplied to the battery 74 via the power receiving terminal 71, and the battery 74 is charged with the current. The gear 73 constitutes a transmission mechanism for transmitting the output of the motor to the tire.

In fig. 4 and 5, the carriage receiving portion 57, the power supply terminal 58, and the metal plate 61 have the same shape. As shown in fig. 5, when the carriage 20 is fitted into the recess 32, the metal plate 61 laterally surrounds the carriage 20.

Fig. 6 is a partially enlarged view of the metal plate 61 shown in fig. 5. The recess 32 has a side wall 81 and a bottom surface, and the side wall 81 is constituted by an inner peripheral surface of the carriage receiving portion 57 and an inner peripheral surface of the opening 86. The metal plate 61 is provided so as to laterally surround the side wall 81. In other words, the side wall 81 is located between the embedded carriage 20 and the metal plate 61. Further, a gap 59 is provided between the upper case member 51 and the carriage receiving portion 57 on the outer side of the side wall 81. The metal plate 61 is disposed in the gap 59. The gap 59 extends to a side wall 81, the side wall 81 being open through the gap 59. The metal plate 61 is exposed from the upper case member 51 and the lower case member 52 through the gap 59.

The metal plate 61 is disposed above (e.g., above the center in the vertical direction) the recess 32. Specifically, the metal plate 61 is connected to the opening of the recess 32, and is adjacent to the end of the guide portion 89 for guiding the finger when detached.

The upper case member 51 has a protrusion 82 protruding downward at an end of the side wall 81 on the gap 59 side. The projection 82 faces the upper end surface of the recess of the carriage receiving portion 57. The end of the metal plate 61 on the opening 65 side is positioned on the upper end surface of the carriage receiving portion 57. The gap 59 is narrowed in the vicinity of the side wall 81 by the protrusion 82. In other words, the distance between the upper case 51 and the lower case member 52 on the side wall 81 is smaller than the distance between the upper case 51 and the lower case member 52 at a position where the metal plate 61 is sandwiched (a region overlapping with the metal plate 61 in a plan view). This makes the metal plate 61 and the gap 59 difficult to visually recognize.

The side surface of the carriage 20 is constituted by the second cover member 77 and the third cover member 78 fitted to each other. Further, a slight gap 79 is present between the second cover member 77 and the third cover member 78, and this gap 79 is also displayed on the side surface of the carriage 20. The side surface of the carriage 20 faces the side wall 81. Here, the distance from the portion closest to the side surface of the carriage 20 in the gap 79 of the carriage 20 to the circuit board 72 is larger than the distance from the portion to the metal plate 61.

Fig. 7 is a perspective view of the metal plate 61 viewed from a direction different from that of fig. 2. The metal plate 61 includes: an electrostatic protection portion 66, a terminal portion 67, and an intermediate portion 68. The electrostatic protection portion 66 is a portion extending in the lateral direction surrounding the opening 65, the terminal portion 67 is a portion contacting the conductive pin 62 on the main board 56, and the intermediate portion 68 is a portion connecting the electrostatic protection portion 66 and the terminal portion 67.

The electrostatic protection portion 66 has a step between an end portion on the opening 65 side and a peripheral edge side of the electrostatic protection portion 66. Which step surrounds the opening 65 in top view. Thus, as shown in fig. 4 to 6, the cross section of the electrostatic protection portion 66 has an S-shaped portion. Due to this step, the electrostatic protection portion 66 is less likely to be deformed, and the metal plate 61 can be disposed with higher accuracy.

The intermediate portion 68 extends downward from a part of the end portion on the peripheral side of the electrostatic protection portion 66, and the boundary between the intermediate portion 68 and the electrostatic protection portion 66 is bent. The width of the intermediate portion 68 becomes narrower as it is farther from the electrostatic protection portion 66. The front end of the intermediate portion 68 is connected to the terminal portion 67. The terminal portion 67 includes: a first region provided with a hole through which the fixing pin 54 passes, a second region connected to the conductive pin 62, a third region connecting them, and an additional region. The first region is a rectangular region provided with a through hole for passing the anchor pin 54 therethrough, and the intermediate portion 68 is connected to one side thereof, the third region is connected to the adjacent one of the sides thereof, and additional rectangular regions are connected to the other two sides thereof. The boundary between the first region and the intermediate portion 68, the boundary between the first region and the third region, and the boundary between the first region and the additional region are bent. The second region is bent in such a manner as to interfere with the conductive pin 62, and is connected to the conductive pin 62 by elastic force. Here, the metal plate 61 may be grounded by another method. For example, the metal plate 61 may be grounded by fixing the terminal portion 67 and the grounded wiring on the main board 56 to each other with a metal screw.

As described above, the distance from the end on the side surface side to the circuit board 72 in the gap 79 of the carriage 20 embedded in the device control apparatus 10 is larger than the distance from the end on the side surface side to the metal plate 61 in the gap 79. When the carriage 20 is fitted into the recess 32 of the device control apparatus 10, the metal plate 61 is discharged before static electricity is discharged to the circuit board 72. A path through which a current generated by electrostatic discharge to the carriage 20 flows is a gap 79 on the exterior of the carriage 20. However, since the metal plate 61 is discharged before the electrostatic discharge through the gap 79 is generated, the carriage 20 can be protected from the electrostatic discharge during charging. When the carriage 20 is charged, the potential supplied from the power supply terminal 58 increases the potential difference between the potential of the circuit board 72 and the object in which static electricity is accumulated, and therefore, there is a high possibility of causing discharge. On the other hand, the possibility of causing electrostatic discharge of the cart 20 is low except during charging. This is because, when the carriage 20 is separated from the device control apparatus 10, the circuit board 72 is not supplied with a potential from the outside, and therefore the potential difference with the object storing static electricity is likely to be small.

Even if there is a carriage 20 on which the battery 74 is mounted and which is difficult to cope with static electricity alone, by providing the conductive member for receiving electrostatic discharge to the device control apparatus 10 on the supply power source side, it is possible to prevent the influence of static electricity during charging, and it is possible to greatly suppress the possibility itself of being influenced by static electricity in normal use of the carriage 20.

Although the present invention has been described as applied to a toy system, the present invention can be applied to electronic devices other than toys and apparatuses for charging the electronic devices. Instead of the trolley 20, other kinds of battery-driven devices may be used. For example, the present invention may be applied to a mobile device such as a smartphone instead of the cart 20.

The charging device for supplying current for charging as in the device control device 10 is not necessarily configured as described above. For example, a conductive film or a ring-shaped metal wire may be used instead of the metal plate 61.

The metal plate 61 having the opening 65 may be disposed on the outer periphery of the upper end of the recess 32, and the opening 65 may surround the recess 32 in a plan view. Since the metal plate 61 is present on the upper side of the housing, the influence of static electricity can be more effectively prevented although there is a decorative restriction. Instead of the metal plate 61, a grounded annular metal wire may be disposed at the upper end of the recess 32 or the outer periphery thereof.

The conductive member, which is disposed around the recess 32 and functions as a so-called lightning rod, may not have an open or annular structure. For example, a plurality of grounded electrodes may be arranged along the upper end of the side wall 81 at intervals smaller than a predetermined value in order to suppress the influence of static electricity. Each of the plurality of electrodes may extend along the side wall 81 in a plan view, or may be a metal line extending in the vertical direction along the side wall 81.

The portion (fitting portion) to be fitted into the battery driving device does not necessarily have to be the recess 32. For example, the fitting portion has a bottom surface and a side wall, but the side wall may not surround the device to be charged. The side surface of the battery driving device may not have a gap, and the charging device may have only a side wall opposite to the side surface without the gap, that is, a side wall provided with the metal plate 61. Further, the portion of the battery driving device disposed for charging may not necessarily be a shape fitting into the battery driving device. For example, the shape of the battery drive apparatus and the shape of the recess 32 may be different. In this case, the same effects as those of the above-described embodiments can be obtained by appropriately disposing the electrodes that receive electrostatic discharge, such as the metal plate 61.
