Description

{Foldable Phone Supporter including Wireless Charging Device}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wireless charger for a portable electronic device folded into a folder type, and more particularly, to a wireless charger capable of wirelessly charging a portable electronic device such as a smart phone in a stand- And more particularly, to a wireless charger capable of charging and enhancing the convenience of using a smart phone.

Smartphones are a vital item in communication and information acquisition among people. Such a smart phone mainly uses an internal battery or an external battery as a power source, and each battery is chargeable. Such a battery charging is mainly performed by directly connecting a charging connector to a smart phone, and recently, a wireless charger capable of being charged without being directly connected to a smart phone has been developed and used. That is, the user can charge the smartphone by simply placing the smart phone on the main body of the charger without any connection between the charger and the charger, so that the charging operation can be accomplished very easily.

Korean Patent Laid-Open Publication No. 10-2014-0039819 discloses an example of such a wireless charger. The wireless charger includes a charging circuit for charging the battery by wireless induction as a charging object. A sensor for detecting proximity of the object to be charged; And a semiconductor switch for amplifying a signal of the sensor and switching to an amplified signal to supply power to the charging circuit and to drive the charging circuit.

However, since the wireless charger simply charges the smartphone on the main body of the charger, even if a light external force is applied, there is a problem that the smartphone is easily detached from the main body of the charger so that the charging can not be performed. So that when the user wants to use the smartphone together with the charging, the user is in a very uncomfortable posture, which causes a problem of hindering user convenience.

Korean Patent No. 10-1738073 also discloses that 'a smartphone can be recharged even when the eye ring is attached to the back of the smart phone, and the eye ring can be fixed to the live part, A smartphone cradle equipped with a wireless charger is disclosed.

However, according to the conventional art having such a structure, since the rotation is formed in a state that the smartphone maintains a specific inclination, it is impossible to change the angle to various angles and thus the usability is reduced. Especially, There is a problem that can not be secured. That is, since the smart phone is fixed to the main body of the charger using the eye ring, there is a problem that it is difficult to stably fix the smart phone without the eye ring.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale and wherein like reference numerals in the various drawings refer to like elements.

FIG. 1 is a perspective view showing a basic configuration of a wireless charger of the present invention, and FIG. 2 is a side view showing a wireless charger of the present invention.

A portable electronic device (10) folded into a folder type according to the present invention has a plate-shaped base (100) which is seated on a floor surface, and a portable electronic device (10) stacked on the upper surface of the base And a wireless charging unit 202 for wirelessly charging the portable electronic device 10 and a supporting table 200 mounted on a boundary portion between the supporting table 200 and the base 100, And a pedestal 400 protruding from the support base 200 in a lower area of the mount 201 and supporting the portable electronic device 10. [

Here, the portable electronic device 10 refers to an electronic device having a wireless charging function such as a portable game device or a tablet PC from a smartphone, and therefore the support device 200 is required to perform wireless charging in association with the electronic device, The portable electronic device 10 further includes a separate induction coil 124 electrically connected to the built-in battery and the support table 200 is also connected to an external power source And is connected to a supply means (preferably a power plug provided in a building or the like) to receive electric power and supply electric power wirelessly through an electromagnetic induction phenomenon.

It is preferable that the base 100 has a structure capable of being fixed on the floor surface so as to have a plate shape. The supporting base 200 is preferably provided in a plate shape similar to the base 100 so that the portable electronic device 10 can be charged while the portable electronic device 10 is mounted on the upper surface. Since the portable electronic device 10 is connected to the base 100 through the pivotal shaft 300, the pivotal shaft 300 can be lifted up and down at a certain angle by the rotation of the pivotal shaft 300 It is needless to say that the portable electronic device 10 can be maintained in a tilted state such as a reading desk. Such a supporting structure can be easily used when the portable electronic device 10 is used (for example, in a movie viewing or a game) while charging is being performed.

In this case, the pivot shaft 300 may further include a separate stopper structure similar to the shaft or the hinge 175. For example, a latching groove (not shown) or a locking protrusion (not shown) 300 and the periphery thereof so that the pivot shaft 300 is rotated to stop the engagement grooves in the latching grooves at specific angles. In recent years, due to the development of material technology, The material and structure capable of fixing the position (for example, when the surface treatment is performed on a material such as polyurethane or silicone, it does not move with a weight of about 200 g, so that the portable electronic device 10 is not deformed Material and structure) have been developed, it is possible to apply such a constitution that the material is coated on the outer circumferential surface of the rotary shaft 300 so that it can be fixed while maintaining a certain angle to be.

Furthermore, the pedestal 400 prevents the portable electronic device 10 mounted on the upper surface of the pedestal 200 from flowing down, especially when the pedestal 200 is erected at a certain angle. Although the upper surface of the support table 200 may be provided with a non-slip structure formed of a material having excellent frictional properties such as rubber, the frictional force of such a structure can not withstand the weight of the portable electronic device 10, The device 10 has a structure in which it is forced to flow down (645). Therefore, it is preferable that the pedestal 400, which is a structure for supporting the portable electronic device 10 at the lower end so that the portable electronic device 10 does not flow down in the gravity direction, is preferably provided.

Of course, the wireless charger has a configuration capable of supplying external power to the supporter 200 through a separate cable (not shown) or vice versa. (Here, the cable is preferably connected to the base 100, It is needless to say that it is necessary to additionally include a separate structure electrically connected to the wireless charging structure of the support table 200 through the pivot shaft 300 and the support table 200 so as to supply electric power, The power supply of the charger or the cradle is not different from that of the charger or the cradle. Therefore, detailed description is omitted here.) The power supply of the wireless charger 202 is supplied to the outside in the reverse order of the existing wireless charging. It is needless to say that an auxiliary structure such as a rechargeable battery (not shown) may be additionally provided.

Furthermore, in the case of the pedestal 400, when the pedestal 200 is in contact with the base 100, the pedestal 400 need not be fully drawn out at all. Particularly, such a wireless charger can be used in a state of being mounted on a desk or the like, but it may be considered that the wireless charger is put in a bag or a bag and used when it is taken out when necessary. Therefore, the configuration in which the base 400 is always drawn out is irritating.

3 is a cross-sectional view showing a lifting structure of the pedestal 400 of the present invention.

A tooth 331 formed along the circumference of the outer circumferential surface of the rotary shaft 300 and a pinion 440 fitted to the teeth 331 in the support table 200, A structure of a pedestal 400 driving unit having a rack 420 mounted on an inner end of the pedestal 400 and moving in the longitudinal direction of the pedestal 200 according to the rotation of the pinion 440 may be provided.

First, a portion where the teeth 331 are formed may be provided on one side of the outer circumferential surface of the rotary shaft 300, and this may serve as a kind of gear. However, a portion where the teeth 331 are formed should be formed at a portion that rotates together with the base 100 on the rotating shaft 300. Further, the pinion 440 may be mounted on the support base 200 through a separate shaft (not shown), which rotates in engagement with the teeth 331. The pinion 440 may be configured to provide a rotational force toward the rack 420. Here, in the case of the rack 420, the upper part of the pinion 440 inside the pedestal 400, as shown in the figure, can be a correct arrangement for its driving.

That is, the pinion 440 is provided at the access portion and rotates in engagement with the tooth 331 while being rotatably coupled by a separate shaft. In this case, the tooth 331 and the pinion 440 may be sized differently from each other to vary the degree of rotation of the teeth 331 and the pinion 440 so that the drawing speed may be different from the rotation of the pivot 300.

In the case of the rack 420, the bar 420 is generally extended in a bar shape to be mounted on the inner end of the pedestal 400, and when the pedestal 400 is moved in the back and forth direction, the pedestal 400 is pushed or pulled to control withdrawal and retraction of the pedestal 400 And to provide a configuration that allows the user to be able to do so. It is preferable that the pull-out and pull-in configurations are configured to protrude when the rack 420 is advanced and to be embedded when the rack 420 is lowered. However, it is a rare case that the configuration is reversed.

4 is a conceptual diagram showing an embodiment in which the lead portion 172 is applied to the base 100 of the present invention.

4A, the base 100 is provided with a base groove 170 embedded in each side of both sides of the base 100, and a plurality of (The entrance side of the base groove 170) so that the drawer or the specific structure can be pulled into the inside of the base groove 170 or can be drawn out to the outside A drawing module 177 including a Bluetooth speaker 173 mounted on the lead-out part 172 and capable of performing wireless communication with the portable electronic device 10 by Bluetooth and outputting sound, .

In other words, it is concluded that the drawing module 177, which is a Bluetooth speaker 173, can be drawn into or drawn out from the base groove 170. It is most preferable that the drawing module 177 has a fan- It goes without saying that any shape can be applied if it is a structure.

At this time, as shown in the side view of FIG. 4 (b), the lead portion 172 is connected to the first lead-out piece 174 and the outer lead 174 of the first lead- And a second lead-out piece 176 which is rotated upward via a hinge 175 formed in the second lead-out portion 176. [ This configuration can have a structure in which the second draw-out 176 is lifted up so that the second draw-out 176 can stand up on the side of the portable electronic device 10, And a structure that can directly support the structure.

Here, the shaft 171 and the hinge 175 may have a separate stopper structure similar to the above-described pivot shaft 300, or the position thereof can be sufficiently fixed through surface treatment.

5 is a side view illustrating an embodiment in which an extension module is applied to the base 100 of the present invention.

Furthermore, the base 100 and the support 200 may be configured to extend to different lengths. Generally, it is a general construction to reduce the length of the base 100 rather than to reduce the length of the base 200 to be charged, so that the base 100 is smaller than the length of the base 200 The extended space 160 may be formed between the support base 200 and the base 100 when the base 100 and the support 200 are in contact with each other. And an extension module 600 detachably coupled to an outer end of the base 100. [

As a general example of such an extension module 600, the extension module may be a speaker (in the case of a speaker, a separate 3.5-pin terminal or Bluetooth connection may be additionally considered), a lighting, a secondary display The base 100 and the expansion module 600 may supply power to the base 100 and supply power to the base 100 and the auxiliary battery 600, respectively, A power supply terminal 161 may be provided.

5, the extension module 600 may include a plurality of extension segments 610 coupled to each other through a coupling portion 611 along the longitudinal direction of the extension space 160. [ The extension section 610 can be configured to have different functions. Here, the engaging section 611 means a protrusion or a groove. If necessary, the protrusion can be protruded. If not necessary, the protrusion can be hidden It should be understood that the present invention is not limited thereto.

The following configuration can be utilized as a configuration capable of utilizing this extended segment 610. [ A speaker output unit 11 may be provided on one side of the outer surface of the portable electronic device 10 to diverge sound output from the built-in speaker to the outside. Accordingly, a plurality of extended segments 610 may have the following configuration .

6 is a conceptual diagram showing an embodiment of an expansion module of the present invention.

6 (a), the extension section 610 can be formed of at least four pieces. The extension section 610 is provided with a coupling terminal 621 at both ends, A coupling hole 631 formed at both ends so as to couple the coupling terminal 621 with the volume larger than that of the sound output fragment 620, A sound reinforcement furnace 632 having a plurality of folded tubular passages through which the coupling holes 631 of both ends are passed and a sound introducing section 633 through which sound output from the speaker output section 11 is introduced 630 and a connecting path 641 for connecting the speaker output portion 11 and an inlet portion 633 of the sound reinforcing slice 630 and an access path 642 for communicating with the connecting path 641, And a connection section 640 having a connection section 643 which is in close contact with the speaker output section 11.

That is, the sound output segment 620 is a region where the sound reinforced by the sound reinforcement segment 630 is output. In the case of the sound reinforcement segment 630, the sound output segment 620 is a sound output segment 630, So that the tone color or the translucent tone is amplified. Particularly, in the case of the sound reinforcement furnace 632, by changing the inner diameter of the sound reinforcement furnace 632 or applying various twisted structures, the sound can naturally change its properties while passing through the sound reinforcement furnace 632, The volume of the sound reinforcing slice 630 is formed to be larger than the sound output slice 620 so as to have the configuration of the sound output slice 620.

Lastly, the connection section 640 is configured to move the sound output from the speaker output section 11 of the portable electronic device 10 by the introduction section 633 of the sound-strengthening section 630. The connection section 643 is a dome (Not shown) formed of a material such as a sponge or a gel can be further applied to the speaker output portion 11 through the sealing structure, It is possible to provide a configuration in which the sound does not escape in a state of being in close contact with the speaker.

In addition, the sound flow path 622 provided in the sound output slice 620 may be formed to be capable of being drawn in and drawn out from both ends of the sound output slice 620 and formed of an antenna structure, So that the sound output slice 620 can be extended and moved to various positions.

The connection section 640 further includes a connection cable 644 capable of being drawn in and out of the connection path 641 in a state in which the through passage is formed along the longitudinal direction of the connection section 640, The length of the connecting cable 644 can be adjusted through the operation of the reel 645 so that the connecting portion 643 connected to the connecting cable 644 can be connected to the reel 645, So that the speaker output unit 11 and the connection path 641 can be connected to each other in a communicable manner. In other words, such a configuration may be utilized as it is positioned behind the base 100 to which the expansion module is originally mounted. However, in a state where the mobile phone is mounted as shown in FIG. 6 (b) It is possible. 6B shows a configuration in which the extension module 600 is mounted on the upper end of the pedestal 400 to increase the support height of the portable electronic device 10 through the extension module 600, When the electromagnetic induction coil is placed at various positions in the wireless charger, the portable electronic device 10 having a variety of lengths and widths is supported through the expansion module 600 so that the portable electronic device 10 can be charged at a high height It is possible to provide an effect of amplifying sound generated from the portable electronic device 10 through the connection slice 640 and the sound reinforcement slice 630 provided in the extension module 600.

At this time, it is possible to provide a configuration capable of providing a surround effect through the sound output segment 620 attached to both sides. At this time, the sound generated from the portable electronic device 10 can be input to the connection slice 640 through the connection portion 643 and the connection cable 644, so that the connection cable 644 is made of a soft material The connecting portion 643 may be made of a soft material or a material such as a gel may be wound around the portable electronic device 10 It is possible to provide a sealing structure which is formed on the surface contacting the speaker output portion 11 of the portable electronic device 10 so as to be wrapped around the speaker output portion 11 so that the wrapped shape is easily fixed and the sound does not escape to the outside.

In this case, the sound of the portable electronic device 10 may be simply received in a Bluetooth manner, and the sound may be provided to the sound reinforcement intercept 630, It is also possible to amplify and output the signal. Accordingly, it is possible to have an entertainment configuration in which sound can be amplified or modified and used in a desired manner through various structural changes.

7 is a perspective view showing the induction coil 124 of the present invention.

The wireless charger 202 further includes a first induction coil 210 for generating an electromagnetic field in a lower region of the supporter 200 and a second induction coil 210 on the upper side of the supporter 200 spaced apart from the first induction coil 210. [ (Not shown) for determining any one of the first induction coil 220 generating an electromagnetic field in the region and the first induction coil generating the induction current in contact with the portable electronic device 10, And a switching module 230 having a power supply controller 232 for supplying power to one of the first and second induction coils 124 and for interrupting the power supply to the other of the first and second induction coils 124 according to the determination of the sensing unit.

Preferably, the first induction coil 210 and the second induction coil 220 are connected in parallel to each other so that no power is supplied to both the coils, thereby minimizing the power loss. Therefore, 210 or the second induction coil 220 conducts wireless charging through the electromagnetic induction phenomenon with the portable electronic device 10, only one of the two coils generates an induced current and the other has only an electromagnetic field . Therefore, if the current sensor is positioned toward each of the induction coils 124, it is possible to determine whether or not an induced current is generated. An environmentally friendly structure capable of minimizing power loss by not supplying power to the induction coil 124 which is not actually used depending on whether or not the drive detection sensor is sensed can be applied.

Of course, when any induction coil 124 continuously generates an induction current, it is no longer necessary to drive the drive detection sensor. However, if the induction current is stopped within a predetermined time (for example, about 5 seconds) It is necessary to change the position of the portable electronic device 10 so that the wireless charging can be properly performed again by allowing the user to flow the current again to each of the induction coils 124. [ Of course.

As described above, the configuration and operation of the portable electronic device wireless charger folded into the folder type according to the present invention are described in the above description and drawings. However, the present invention is not limited to the above description and drawings. And it is to be understood that various changes and modifications may be made without departing from the spirit of the invention.
