Description

Background Art Technical Field

[0001] Aspects of the present disclosure are directed to a multi-device wireless charger and methods of using the same that may be implemented in various environments, such as in a vehicle. Background Art

[0003] The earliest version of the modern smartphone was commercially released by IBM in 1994 and was capable of receiving and sending faxes, emails, cellular calls, etc. However, with the exponential scaling and miniaturization of metal oxide semiconductor field effect transistors combined with the development of the Internet, smartphones have been rapidly integrated into everyday life within the social structure. In addition to multiple other devices such as calculators, portable music players, etc., the introduction of smartphones may begin to reduce the number of home landline systems due to their portability, at least in part because such a wide variety of functions can be incorporated into smartphones. For example, the use of paper maps or stand-alone global positioning system (GPS) navigation devices while driving was soon replaced by the use of Internet-connected maps and navigation programs, which began to be standard in almost all smartphones. In another example, smartphones replace traditional radio technology or portable music players because in some cases, they become the preferred medium for playing music, podcasts and other audio media, especially in mobile environments, including in vehicles or airplanes.

[0004] Thus, due at least in part to the increased use of smartphones in vehicular environments, there has been a similar increase in the need and creation of a variety of different charging methods that can be implemented in environments where wall plug charging is available. However, the use of maps and music on smartphones has led to an increase in the number of automobile accidents, some of which have been fatal, at least in part because drivers often take their eyes off the road while attempting to operate the device. Thus, there has been a similar increase in the need for a device that holds a smartphone device in place so that the driver can at least check for directions without needing to look at their lap or any other position that would require losing focus on the road they are driving on.

[0005] In the related art, there are examples of devices that combine wireless charging technology with a smartphone locating device for implementation within a vehicle environment. For example, there are devices that can be attached to the inside of a windshield so that a phone can be clipped into place, where the platform holding the device is configured to wirelessly charge the smartphone. However, the configuration of these devices is limited. Specifically, only a single wirelessly chargeable device can be clipped in at a time, and the device can be configured to accommodate only one unique commercial implementation or a small range of commercial implementations of a smartphone. In addition, these devices cannot charge or hold other wirelessly chargeable devices, such as tablets and headphones.

[0006] Therefore, in response to the above-mentioned problems and other problems, there is an unmet need in the related art for a multi-device wireless charging system and method of use thereof, which is used to be implemented in various environments (such as in a vehicle). Summary of the invention

[0007] Due to the above-referenced deficiencies and others, there remains an unmet need for a wireless charging device capable of simultaneously charging multiple similar or dissimilar devices in a variety of environments, such as in a vehicle.

[0008] In view of such problems and shortcomings, various aspects of the present disclosure relate, in particular, to multi-device wireless charging devices, systems, and methods of using the same. According to various aspects, an exemplary multi-device wireless charger may include a charging surface disposed within a housing structure, wherein the housing structure may accommodate electronic or technical equipment necessary to achieve wireless charging, such as a receiving coil and / or other features necessary to achieve wireless charging via electromagnetic induction. In addition, the housing structure may also include an adjustable fixing feature, wherein the adjustable fixing feature facilitates adjustment of the multi-device wireless charger to securely accommodate at least two wirelessly chargeable mobile devices, including where the at least two devices are different devices. In one example, the adjustable fixing feature may include a drum-shaped sliding surface disposed on top of the charging surface, such that the drum-shaped sliding surface includes a larger surface area than the charging surface, and wherein an extension of the drum-shaped sliding surface is configured to be stored within the charging device, such as stored below the charging surface. The fixation may further include an adjustment mechanism, wherein the adjustment mechanism is attached to the drum-shaped sliding surface, such that the adjustment mechanism branches the drum-shaped sliding surface. The adjustment mechanism can be used to adjust the drum-shaped sliding surface to accommodate one or more wirelessly chargeable mobile devices, such as one or more smart phones, tablets, or earbud charger devices, at the same time. In another example, the fixed feature may include at least two spring-loaded clamping mechanisms or other fixed features and a separator member, which is configured to branch the charging surface. The spring-loaded clamping mechanism may be located, for example, on either side or both sides of the separator member. In yet another example, the fixed feature may include at least two spring-loaded sliding mechanisms, each of which is configured to interoperate with a stabilizing member via at least two springs. The fixed feature can facilitate simultaneous wireless charging of the at least two wirelessly chargeable devices, for example, allowing continued use and operation of these devices in a mobile setting (such as in a vehicle or an aircraft).

[0009] In addition, according to various aspects of the present disclosure, a method for using a multi-device wireless charging system may include adjusting the securing feature according to the size, shape, and / or packaging of each of the wirelessly chargeable devices that interoperate therewith, and securing each wirelessly chargeable device within the multi-device wireless charging system relative to the charging surface. In one example, a protruding member may be used to position a drum-shaped sliding surface, wherein the wirelessly chargeable device may then be positioned on the sliding drum surface and secured via a gripping mechanism of a clip, retainer, or other similar device. In another example, a spring-loaded clamping mechanism may be adjusted with the wirelessly chargeable device relative to the wireless charging surface, wherein the wirelessly chargeable device is then, for example, placed on the charging surface and secured relative to the charging surface by the spring-loaded gripping mechanism. In yet another example, a spring-loaded sliding mechanism may be adjusted relative to the wireless charging surface to accommodate the wirelessly chargeable device, wherein the wirelessly chargeable device is then inserted relative to the spring-loaded sliding mechanism, the spring mechanism, and the stabilizing member and secured by their interoperation.

[0010] Additional advantages and novel features of these aspects will be set forth in part in the following description and will in part become more apparent to those skilled in the art upon reading the following description or learning from practice of the present disclosure.

[0028] The detailed description set forth below in conjunction with the accompanying drawings is intended as a description of various configurations and is not intended to represent the only configuration in which the concepts described herein may be practiced. The detailed description includes specific details used to provide a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details.

[0029] Throughout this disclosure, the term "approximately" may be used as a modifier of the geometric relationship between elements or the shape of an element or component. Although the term "approximately" is not limited to a specific variation and may encompass any variation that a person of ordinary skill in the art understands to be an acceptable variation, some examples are provided below. In one example, the term "approximately" may include a variation of less than 10% of the size of an object or component. In another example, the term "approximately" may include a variation of less than 5% of an object or component. If "approximately" is used to define the angular relationship of one element to another, a non-limiting example of the term "approximately" may include a variation of 5 degrees or less. These examples are not intended to be limiting and may be increased or decreased based on the understanding of acceptable limits by a person of ordinary skill in the relevant art.

[0030] For the purposes of this disclosure, when the systems and devices described herein are installed in an orientation in use, directional terms are generally expressed relative to a standard reference system. In addition, to provide context for this disclosure, a broad overview of the defects found in various systems and exemplary embodiments of the present disclosure and the advantages provided by the present disclosure is described below. More details of the exemplary embodiments of the present disclosure are described in detail with reference to the following drawings.

[0031] According to aspects of the present disclosure, Figure 1Various features of an exemplary multi-device wireless charger 100 are shown, wherein the charger 100 includes a charging surface 104, wherein the charging surface 104 can be configured to wirelessly charge a plurality of different wirelessly chargeable devices having different shapes and / or in different packaging or other features, such as wireless earbud buds, smartphones, or tablets, for example, via placement on or near the charging surface 104. For example, the charging surface 104 can be configured to enable inductive charging of devices configured to be charged via electromagnetic induction. In an exemplary embodiment, the surface 104 can operate under the Qi standard, wherein a system based on the Qi standard can include two components: a base station, wherein the base station is connected to a power source and provides power relative to a second component (e.g., a mobile device), wherein the mobile device is not directly connected to the power source and can consume inductive power to charge it. In this system, the base station can include a power transmitter, wherein the power transmitter includes a transmit coil or other features that generate an oscillating magnetic field or otherwise varying magnetic field. In addition, the mobile device can include a power receiver, wherein the power receiver can include a receive coil or other inductive receiving component for receiving power or energy from the base station transmitter. In one example, the inductive charging surface 104 may require direct alignment of a coil or other inductive receiving feature of a mobile device with a transmitting coil of a base station. However, other exemplary embodiments may not require direct alignment of the receiving coil and the transmitting coil to achieve wireless charging. For example, other such embodiments may have features or arrangements that enable wireless charging, where the base station includes multiple transmitting coils in a variably arranged manner, and / or the mobile device may include multiple receiving coils.

[0032] in addition, Figure 1 The charger 100 also includes an adjustment module 102 attached to or otherwise interoperable with a drum-shaped (or drum-skin-shaped, tambour) sliding surface 103. The adjustment module 102 can be or include ribs, such as Figure 1 As shown, however, the adjustment module 102 may also be or include a protrusion, multiple protrusions, a recess, or multiple recesses, or other similar one or more features, wherein the adjustment module 102 may have features that facilitate the user to adjust the position of the drum-shaped sliding surface 103. In addition, as also shown Figure 2As shown, when the charger 100 is placed in a position for use by placing a device thereon, the charging surface 104 can be disposed on the housing structure 106, and the drum-shaped sliding surface 103 can be additionally disposed on the top side of the charging surface 104. The drum-shaped sliding surface 103 can be configured to slide so that the adjustment module 102 can divide the charging surface 104 into at least two different sections, wherein the sizes of the at least two different sections can vary to include a range of different relative surface areas. Thus, the surface area of ​​the drum-shaped sliding surface 103 can be larger than that of the charging surface 104, wherein the portion of the drum-shaped sliding surface 103 that is not disposed on top of the charging surface 104 (depending on the position of the adjustment module 102) can be wrapped around or under the charging surface 104, as shown in FIG. Figure 2 Thus, the drum-shaped sliding surface 103 may include a material that is sufficiently flexible to facilitate such movement and operation.

[0033] In addition, the housing structure 106 can be configured to house various electronic and / or other functional components 112, wherein such technology components 112 can be configured to enable wireless charging via the charging surface 104. The technology components 112 may include a transmitting coil or other similar electromagnetic induction transmitting components configured to transmit electromagnetic power via induction, a control unit, wherein the control unit may include a processor and memory, a battery, etc. In addition, a clamping member 108 can be secured to the housing structure 106, wherein the clamping member 108 can be configured to facilitate securing the charger 100 to a variety of different surfaces, such as a dashboard or console in a vehicle. Therefore, the clamping member 108 may include a sufficiently rigid material, such as plastic, metal, glass, or some combination thereof. In one example, the charger 100 may begin charging the wirelessly chargeable device immediately when placed on the drum sliding surface 103. However, as Figure 1 As shown, the charger 100 may alternatively include a power switch 110 that may be configured to selectively cause operation of inductive charging when pressed, turned, flipped, etc. This configuration may allow a user to control whether and / or when a wirelessly chargeable device is charged, for example, allowing the charger 100 to retain a wirelessly chargeable device even if the device would otherwise be damaged if further charged (in the absence of such control).

[0034] According to various aspects, Figure 2 A cross-sectional side view of a charger 100 is shown, wherein the charger 100 comprises a housing structure 106, wherein the housing structure 106 accommodates technical components 112. In addition, Figure 2A drum-shaped sliding surface 103 is shown that is configured to be at least partially positioned on top of a charging surface 104, wherein the relative portion and / or position of the drum-shaped sliding surface 103 can be adjusted relative to the charging surface 104. The portion of the drum-shaped sliding surface 103 that is not positioned on top of the charging surface 104 can be configured to wrap around, for example, the charging surface 104 and the technology component 112 below, so that the drum-shaped sliding surface 103 does not extend beyond the housing structure 106 or extend outside the housing structure. Therefore, in order to facilitate such positioning and movement, for example, the drum-shaped sliding surface 103 may include a sufficiently flexible material or a ribbed non-flexible material so that the drum-shaped sliding surface 103 can flex via an accordion-like movement.

[0035] According to various aspects of the present disclosure, Figure 3 1 shows a side view of the charger 100, wherein the charger 100 further includes a clamping member 108, a first attachment mechanism 114a, and a second attachment mechanism 114b. The attachment mechanisms 114a, 114b can be configured to facilitate secure placement of the charger 100 in a variety of different environments. In one example, the attachment mechanisms 114a, 114b can have or include one or more clips ( Figure 3 114a, 114b) such that the one or more clips can secure the charger 100 to or in a center console in a vehicle environment. However, in alternative exemplary embodiments, the attachment mechanisms 114a, 114b may include suction devices, magnetic elements, and / or other securing features that can be used to securely attach the console to a dashboard or other similar surface in a vehicle or non-vehicle environment (such as in an aircraft cockpit).

[0036] According to various aspects, FIG. 4A to FIG. 4D Several views of an exemplary wirelessly chargeable device positioned to interoperably engage with charger 100 are shown. Specifically, Figure 4A An exemplary configuration for simultaneously placing and / or charging a first smart phone device 410A and a second smart phone device 410B is shown. Figure 4A As shown, the conditioning module 102 may be located approximately in the center of the charging surface 106. Additional devices 410a-410b may be secured to the charger 100 via one or more clip portions 108 such that the device 410a may securely interoperate with the charging surface 104.

[0037] Figure 4BAnother exemplary configuration is shown in which a smart phone device 412 and an earbud charging device 414 are positioned for charging at the same time. In configuration 404, the adjustment module 102 can be selectively positioned so that the adjustment member divides the charging surface 106 unequally so that the smart phone device 412 and the earbud charging device 414 can be wirelessly charged at the same time. Similar to configuration 402, configuration 404 allows devices 412 and 414 to be securely molded to the charging surface 106 via one or more clip portions 108.

[0038] Figure 4C Yet another exemplary configuration is shown in which the adjustment module 102 can be positioned to one side of the surface 106 so as not to interfere with the secure retention of the smart phone device 416 via the clip portion 108. This positioning of the adjustment module 102 allows the device 416 to be secured within the charger 100 so that the device 416 can securely interoperate with the charging surface 104.

[0039] Similar to Figure 4C The configuration, Figure 4D An exemplary configuration is shown in which a tablet device 418 is secured within the charger 100 via the clip portion 108, and the conditioning module 102 is positioned to one side of the charging surface 104 so as not to interfere with the secured device 418. In combination, FIG. 4A to FIG. 4D A variety of wirelessly chargeable devices are shown as being interoperable with charger 100 (one device at a time or multiple devices simultaneously).

[0040] According to various aspects of the present disclosure, Figure 5 An exemplary multi-device wireless charger 500 is shown including a plurality of sliding armatures (such as sliding armatures 502a-502d) secured to a charging surface 504, wherein the charging surface 504 may be disposed within a housing structure 505. Figure 1 As shown in the charging surface 104, the charging surface 504 can be configured to wirelessly charge a plurality of different wirelessly chargeable devices having different shapes and / or using different packaging or other features via placement on or near the charging surface 504. Specifically, the charger 500 can be configured so that a receiving coil or other inductive receiving feature included in the wirelessly chargeable device can be fixed by the sliding armatures 502a-502d to be directly aligned with a transmitting coil or other inductive transmitting feature included in the charger 500. Therefore, the charger 500 can allow for more efficient wireless charging of a plurality of different wirelessly chargeable devices.

[0041] Sliding armatures 502a and 502c can be securely secured to charging surface 504 via channel 506a, wherein sliding armatures 502b and 502d can be securely secured to charging surface 504 via channel 506b. Channels 506a and 506b can be formed by generally linear recesses, wherein channels 506a and 506b can be generally parallel, wherein channels 506a and 506b can be positioned near opposite edges of charging surface 504, such as Figure 5 As shown. Sliding armatures 502a and 502c may constitute a first pair of cooperating sliding armatures, wherein sliding armatures 502b and 502d may constitute a second pair of cooperating sliding armatures. In one example, the first pair of cooperating sliding armatures may operate independently of the second pair of cooperating sliding armatures. However, it is also possible that the first pair of cooperating sliding armatures and the second pair of cooperating sliding armatures may also be configured to be coordinated.

[0042] In an example such as Figure 5 In the example shown in FIG. 1 , the cross-section of the sliding armatures 502a-502d can be rectangular, wherein each of the sliding armatures 502a-502d further includes a fixed end 510a-510d. The fixed end 510a of the sliding armature 502a can be configured to engage the channel 506a, so that the sliding armature 502a can be movably positioned between a center point 512a and a first outer point 514a, wherein the point 512a can be defined by the location where the center line 508 branches off the channel 506a, wherein the outer point 514a can be defined by a first end edge of the channel 506a. Similarly, the fixed end 510c of the sliding armature 502c can also be configured to engage the channel 506a, so that the sliding armature 502c can be movably positioned between the center point 512a and a second outer point 515a, wherein the second outer point 515a can be positioned on the opposite end edge of the channel 506a. The sliding armatures 506 a and 506 c may be configured such that they move uniformly in opposite directions relative to each other and relative to the central axis 508 .

[0043] In contrast, the sliding armatures 502b and 502d can be configured similarly to the sliding armatures 502a and 502c, except that the sliding armatures 502a, 502b can be configured to engage the channel 506b. For example, the fixed end 510b of the sliding armature 502b can be movably positioned between the center point 512b and the first outer point 514b, wherein the point 512b can be defined by the location where the center line 508 branches off the channel 506b, wherein the first outer point 514b can be defined by the first end edge of the channel 506b. Similarly, the fixed end 510d of the sliding armature 502d can also be configured to engage the channel 506b, so that the sliding armature 502d can be movably positioned between the center point 512b and the second outer point 515b, wherein the second outer point 515b can be positioned on the opposite end edge of the channel 506b. The sliding armatures 506 b and 506 d may be configured such that they move uniformly in opposite directions relative to each other and relative to the central axis 508 .

[0044] The sliding armatures 502a-502d can be configured to be movably positioned by a spring force mechanism, such that the spring force mechanism can cause each of the sliding armatures 502a-502d to be stationary when positioned approximately adjacent to the centerline 508. However, in another example, the sliding armatures 502a-502d can be movably positioned by any other suitable biasing member or other biasing mechanism or mechanism system that can generate a force that biases each of the armatures 502a-502b toward the centerline 508. Due to the force generating mechanism employed, when the sliding armatures 502a and 502c are movably positioned away from the centerline 508, the sliding armatures 502a and 502c can apply a fixed force to an object placed therebetween. For example, if a wirelessly chargeable device is positioned between sliding armatures 502a and 502c, sliding armatures 502a and 502c can apply a compressive force toward the centerline such that the wirelessly chargeable device is secured between sliding armatures 502a and 502c on charging surface 504. The same process can be used with sliding armatures 502b and 502d so that two different wirelessly chargeable devices can be simultaneously secured to charging surface 504. Furthermore, because sliding armatures 502a and 502c operate independently of 502b and 502d, each corresponding pair of sliding armatures can accommodate wirelessly chargeable devices of different sizes and / or shapes.

[0045] According to various aspects of the present disclosure, Figure 6 Various structures are shown in a cross-sectional close-up perspective view, which shows the mechanism of the movably positioned sliding armatures 510a and 510c. Figure 6 The illustrated sliding armatures 510a and 510c include an inlet portion located below the charging surface 504 of the exemplary multi-device wireless charger 500. Figure 6In the embodiment of the present invention, the sliding armature 502a can interoperate with the first bearing 602a via the first shaft portion 603a, and the first gear 604a can rotate around the first shaft portion. Similarly, a portion of the sliding armature 502c can engage with the second gear 604c, which rotates around the second shaft portion 603c, and the second shaft portion 603c in turn interoperates with the second bearing 602c. The first gear 604a can include a plurality of extended teeth 606a, wherein the teeth 606a can engage with a plurality of corresponding extended teeth extending from the sliding armature 502a. Similarly, the second gear 604c can include a plurality of extended teeth 606c, wherein the extended teeth 606c can engage with a corresponding plurality of extended teeth 608c of the sliding armature 502c. Therefore, when the gears 604a and 604c rotate via the force applied to the corresponding sliding armatures 502a and 502c, the positioning of the sliding armatures 502a and 502c relative to each other is synchronized. Furthermore, in one example, the bearings 602a and 602c, the shaft portions 603a and 603c, and the gears 604a and 604c can be positioned directly below the channel 506a, such as Figure 6 However, in another example, bearings 602a and 602c, shaft portions 603a and 603c, and gears 604a and 604c may be positioned within recesses of channel 506a. Figure 6 Not visible in FIG. 5 , but sliding armatures 502b and 502d may be similarly configured within channel 506b with corresponding bearings, shafts, and gears, similar to that described above.

[0046] According to aspects of the present disclosure, Figure 7 1 shows a cross-sectional side view of various features of an exemplary multi-device wireless charger 500 according to aspects of the present disclosure. Figure 5 and Figure 6 As shown, in Figure 7, the charger 500 includes a sliding armature 502a and a sliding armature 502c shown in a rest position approximately near a centerline 710, wherein the sliding armature 502a includes a surface-side interaction portion 706a, and the sliding armature 502c includes a surface-side interaction portion 706c, wherein the interaction portions 706a and 706c are positioned above or on top of the surface of the wireless charging surface 504. The interaction portions 706a and 706c can be configured to interoperate with a plurality of different wirelessly chargeable devices, such as a tablet, a smart phone, or an earbud charger. In addition, the sliding armature 502a can also include a force generating portion 708a, and the sliding armature 502c can include a force generating portion 708c, wherein portions 708a and 708c are located below or on opposite sides of the wireless charging surface 504 relative to portions 7061, 706c. Portions 708a and 708c may extend approximately half the length of charger 500 such that portions 708a and 708c may provide stability relative to interacting portions 706a and 706c. Additionally, portions 708a and 708c may be configured with engageable teeth such that movement of sliding armatures 502a and 502c may be coordinated to occur simultaneously via operation of one or more gears having corresponding teeth that may engage therewith. Figure 7 502b and 502d ( Figure 7 In addition, the charger 500 may include a return spring 702, wherein the return spring 702 may be configured to generate a force that biases the sliding armature 502a toward the center line 710. Similarly, the charger 500 may also include a return spring 704, wherein the return spring 704 may be configured to generate a force that biases the sliding armature 502c toward the center line 710. Although Figure 7 Not shown, but charger 500 may also include additional return springs, one of which may interoperate with sliding armature 502b, and another of which may interoperate with sliding armature 502d, similar to the operation of return springs 702 and 704 described above.

[0047] According to aspects of the present disclosure, FIG. 8A to FIG. 8D Shown with Figure 5 5 is a diagram of an exemplary multi-device wireless charger 500 that engages multiple examples of wirelessly chargeable devices.
