Description

  The present invention belongs to a technical field of a non-contact power feeding device for a flat display, and particularly to a technical field of a non-contact power feeding device for a flat display that supplies power to a power receiver by non-contact electromagnetic induction from the power feeder.

  In recent years, research and development on various flat displays have been actively conducted. As one of them, a display using organic EL (Electro Luminescence) has been developed to a practical stage. This organic EL display has features such as high brightness, high definition, high reaction speed, and high viewing angle, and is expected as a next-generation display device.

  In addition, the organic EL display has a feature that it can be configured as a display device that is thin and bendable like paper because of its structure. As an application of this feature, posters and the like can be displayed. By constructing the object itself with an organic EL display, it is also possible to realize a display with a markedly improved visual effect as a posted object.

  Here, when the posting is constituted by the organic EL display as described above, it is naturally necessary to supply electric power for driving the organic EL display as the posting at the time of the posting. And considering that it is necessary to be able to attach to and detach from the posting place such as a wall as a characteristic of the posting thing, it is considered that each of the above posting place and the posting thing can be considered as a power supply by the conventional method. It is conceivable that an electrical contact is provided to the bulletin board so that power is supplied to the bulletin board from a power supply source provided at the bulletin board.

  However, in the case of power supply through such an electrical contact, the electrical contact degree is reduced by repeating the attachment and detachment many times (that is, the resistance value at the contact increases), thereby supplying power. Has the problem of becoming inefficient. In addition, in the case of electrical contacts, the metal part is exposed to the outside air, and therefore, there is a problem that it cannot be used for power supply to outdoor postings due to problems such as corrosion or rust.

  Therefore, in view of such problems, a non-contact type power supply device using an electromagnetic induction action has been studied as a power supply device for the above-described light-emitting display material, instead of a conventional device using an electrical contact. Yes.

  Therefore, when the heat sink of the power receiver is thinly formed so as to be substantially flush with the organic EL display, the heat generated from the three-terminal regulator cannot be radiated and the organic EL display is affected by heat. There is a possibility of damage.

  Conversely, it is possible to dissipate the heat generated by the three-terminal regulator by attaching a thick heat sink to the power receiver. However, if the heat sink is made thicker, the organic EL display must be thin. Therefore, a step is generated between the organic EL display and the power receiver, so that the appearance is very bad, and the visual effect as a posting is greatly reduced.

The heat absorbing pad 42 is formed in a shape that bulges outward from the pad case 41 and the opening 40.

  Further, the heat absorbing pad 42 is made of a soft silicone resin or a urethane resin containing a metal filler, and is held by the power feeder 3 and the side that contacts the heat sink 23 of the power receiver 2 when power is supplied from the power feeder 3 to the power receiver 2. Both sides on the back side are sticky. That is, the heat absorbing pad 42 is selected from a material having high adhesiveness, thermal conductivity, and durability that can withstand repeated use.

  An aluminum heat transfer plate 43 is disposed between the pad case 41 and the back plate 38. A surface of the back plate 38 other than the mounting side of the heat absorbing pad 42, that is, a surface opposite to the surface of the mounting side of the heat absorbing pad 42, is integrally molded from aluminum die cast or the like, and serves as a heat radiating member formed with heat radiating fins 44a. A plurality of heat sinks 44 are fixed side by side.

  Note that the heat radiating plate 23 of the power receiver 2, the pad case 41 of the power feeder 3, the heat transfer plate 43, and the back plate 38 may be formed of a metal having high thermal conductivity other than aluminum. Further, a synthetic resin is filled between the cover sheet 37 and the back plate 38 in order to position and fix the power feeding circuit 31, the pot-type core 39, the power feeding coil 32, and the like.

  Next, the operation of this embodiment will be described.

  First, the power receiver 2 with the power receiving coil 11 exposed in advance is connected to the lower side of the display 1. At the time of rapid charging, the power supply 3 is held and the positioning pin 36 of the power supply 3 is inserted into the positioning hole 18 of the power reception device 2 so that the cover sheet 37 of the power supply 3 is in close contact with the cover sheet 19 of the power reception device 2. Position so that.

Then, the power feeding coil 32 is close to and parallel to the power receiving coil 11, and is in a positional relationship.
The distance between the pot-type core 21 and the pot-type core 39 is 0.4 to 0.7 mm. Therefore, the power feeding coil 32 of the power feeder 3 is arranged at a position facing the power receiving coil 11, and the current from the storage battery 4 is caused to flow through the power feeding coil 32 so as to face the power feeding coil 11 by electromagnetic induction. An induced current is generated in the power receiving coil 32, the storage battery 15 connected to the power receiving coil 32 is rapidly charged by the induced current, and the display 1 as a display object is driven by the power.

  At this time, the three-terminal regulator 13a of the power receiving circuit 13 starts charging when heat is generated and the core gap range between the pot-type core 21 and the pot-type core 39 is 0.5 to 0.7 mm. To 61-78 ° C. in about 10 minutes. Thereby, the heat sink 23 of the power receiver 2 also has substantially the same temperature.

  Therefore, in this embodiment, when the cover sheet 37 of the power feeder 3 is positioned so as to be in close contact with the cover sheet 19 of the power receiver 2, the heat absorption pad 42 of the power feeder 3 bulges to the outside. 42 enters the opening 22 of the power receiver 2 and closely contacts the heat sink 23 to absorb heat. The heat absorbed by the heat absorbing pad 42 is transferred through the aluminum pad case 41, the heat transfer plate 43, and the back plate 38, and then efficiently dissipated from the plurality of heat sinks 44.

  As described above, according to the present embodiment, the power receiver 2 is connected to the display 1. When the power receiver 2 is directly opposed to the power receiver 2 and power is supplied from the power feeder 3 to the power receiver 2, the power receiver 2 is connected. By providing the power feeder 3 with the heat absorbing pad 42 that contacts and absorbs the heat, the heat generated in the power receiver 2 is absorbed by the heat absorbing pad 42 of the power feeder 3 during rapid charging. Even if the power receiver 2 is thinned without including a large heat radiating member in the electric device 2, a good heat radiating effect can be obtained. As a result, the display 1 is not thermally affected, and the display 1 is not damaged. Can be prevented.

  Further, according to the present embodiment, a plurality of heat sinks 44 are arranged on the surface of the power feeder 3 other than the mounting surface of the heat absorbing pad 42, specifically, the surface opposite to the mounting surface of the heat absorbing pad 42 of the back plate 38. By conducting the heat absorbed by the heat absorbing pad 42 to the heat sink 44, the heat absorbing effect on the power receiver 2 can be enhanced.

  Furthermore, according to the present embodiment, since the heat sink 44 includes the plurality of heat radiation fins 44a, the heat absorbed by the heat absorption pad 42 can be efficiently radiated.

  According to the present embodiment, the heat absorption pad 42 is made of either a soft silicone resin or a urethane resin containing a metal filler, so that the adhesiveness when contacting the heat sink 23 of the power receiver 2 is high, Since the conductivity is high, the heat of the power receiver 2 can be efficiently absorbed.

  In addition, according to the present embodiment, the heat sink 23 having high thermal conductivity is disposed at the site of the power receiver 2 where the heat absorbing pad 42 of the power feeder 3 contacts, so that the heat generated in the power receiver 2 is 3 can be reliably and efficiently transmitted to the three heat absorbing pads 42.

  Furthermore, according to the present embodiment, the heat absorption pad 42 has adhesiveness on both sides of the power receiver 2 on the side contacting the heat radiating plate 23 and the side held by the power feeder 3. A good endothermic effect is obtained by closely contacting the heat sink 23. Moreover, since the heat absorption pad 42 adheres reliably without floating from the side held by the power feeder 3, a good heat radiation effect can be obtained.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, in the above-described embodiment, the heat absorption pad 42 is mounted in the pad case 41. However, if the pad case 41 with the heat absorption pad 42 is configured to be detachable from the power receiver 2 as a unit, the adhesiveness and the like can be improved. If the characteristics deteriorate, they can be easily replaced.

  As an attachment / detachment mechanism for the pad case 41 with respect to the power receiver 2, for example, a storage recess of the pad case 41 is formed along the width direction of the power feeder 3, and a groove is formed on the wall surface of the storage recess. There is a mechanism for forming a portion that fits into the groove on the side surface of the pad case 41.

  With this configuration, when the heat absorbing pad 42 is replaced, the heat absorbing pad 42 can be easily removed from the power feeder 3 by pulling out the portion of the pad case 41 along the groove of the power feeder 3. In addition, the heat absorbing pad 42 can be easily attached to the power feeder 3 by inserting the portion of the pad case 41 along the groove of the power feeder 3. Further, this attachment / detachment mechanism can be provided in the power feeder 3 without increasing the thickness of the power feeder 3.
