DETAILED DESCRIPTION
[0011] FIG. 1 is a perspective view of an exemplary vehicle 10 that may include a vehicle interior component having a wireless charging indicator. As illustrated, the vehicle 10 includes an interior 12 having a seat 14, a floor console 16, and a center console 18. In certain embodiments, the vehicle 10 includes a wireless charging system having a power transmission module in electromagnetic communication with a show surface of the center console 18. In such embodiments, the power transmission module is configured to transfer energy to a power receiver module of a portable electronic device positioned adjacent to the show surface.
[0012] As discussed in detail below, the center console 18 also includes a wireless charging indicator positioned adjacent to the power transmission module. The wireless charging indicator is configured to provide an indication of alignment between the power transmission module and the power receiver module, to provide an indication of power transfer from the power transmission module to the power receiver module, and/or to provide an indication of a state of charge of the portable electronic device. For example, the wireless charging indicator may provide a visual, audible, and/or haptic indication when the portable electronic device is placed adjacent to a desired region of the show surface of the center console 18, thereby indicating that the power transmission module is substantially aligned with the power receiver module. In addition, the wireless charging indicator may provide a visual indication (e.g., via illumination of the show surface) of power transmission to the portable electronic device. Furthermore, the wireless charging indicator may provide an indication when the portable electronic device is fully charged, and/or may indicate the state of charge of the portable electronic device.
[0013] While the wireless charging indicator is described below with reference to a center console 18, it should be appreciated that additional areas of the vehicle interior 12 may include a similar wireless charging indicator. For example, in certain embodiments, a door panel, a floor console, an instrument panel, an overhead console, a vehicle seat, and/or an armrest may include a wireless charging system having a wireless charging indicator. Moreover, it should be appreciated that the wireless charging system described below may be employed within other types of vehicles, such as boats, airplanes, buses, trains, and motorcycles, for example.
[0014] FIG. 2 is a perspective view of a part of the interior 12 of the vehicle 10 of FIG. 1. In the illustrated embodiment, the center console 18 includes a wireless charging system 20 configured to charge portable electronic devices placed adjacent to a show surface 21 of the center console. As illustrated, the wireless charging system 20 includes a power transmission module 22 positioned beneath the show surface 21 of the center console 18. The power transmission module 22 is configured to wirelessly transfer energy to a power receiver module of a portable electronic device while the portable electronic device is adjacent to the show surface 21. In the illustrated embodiment, the wireless charging system 20 includes an icon 24 to indicate the desired placement location of the portable electronic device on the show surface 21. [0015] The wireless charging system 20 also includes a wireless charging indictor 26 positioned adjacent to the power transmission module 22. In the illustrated embodiment, the wireless charging indicator 26 is configured to provide a visual indication of alignment between the power transmission module and the power receiver module, to provide a visual indication of power transfer from the power transmission module to the power receiver module, and/or to provide a visual indication of a state of charge of the portable electronic device. For example, the wireless charging indicator 26 may display a graphical representation of alignment, power transfer, and/or state of charge. As illustrated, a bar graph presented by the wireless charging indicator 26 represents a state of charge of the portable electronic device. However, it should be appreciated that the wireless charging indicator 26 may present other graphical indications of state of charge in alternative embodiments. For example, the wireless charging indicator may present a pie graph, a line graph, and/or a series of illuminated dots. As indicated above, the wireless charging indicator may also provide a graphical representation indicating alignment of the power transmission module with the power receiver module, and/or a graphical representation of power transfer to the portable electronic device.
[0016] As discussed in detail below, the wireless charging indicator 26 may also provide a visual indication of alignment, power transfer, and/or state of charge via multiple light emitting assemblies, each configured to illuminate a respective portion of the show surface 21. Furthermore, the wireless charging indicator may provide an audible and/or tactile indication of alignment, power transfer, and/or state of charge. As a result, an occupant may receive feedback throughout the wireless charging process.
[0017] FIG. 3 is a block diagram of an embodiment of a wireless charging system 20 having a wireless charging indicator 26. As illustrated, a portable electronic device 30 is placed on the show surface 21 of the center console 18 adjacent to the power transmission module 22. As previously discussed, the power transmission module 22 is configured to wireless transfer energy to a power receiver module of the portable electronic device 30, thereby charging the device. In the illustrated embodiment, a controller 32 (e.g., having a processor and memory) is communicatively coupled to the power transmission module 22 and to the wireless charging indicator 26. The controller 32 is configured to adjust an output of the wireless charging indicator to provide an indication of alignment between the power transmission module and the power receiver module, to provide an indication of power transfer from the power transmission module to the power receiver module, and/or to provide an indication of a state of charge of the portable electronic device.
[0018] In the illustrated embodiment, the wireless charging indicator includes a visual indicator configured to illuminate the show surface 21 of the center console 18 adjacent to the power transmission module 22. As illustrated, the wireless charging indicator 26 includes a first light emitting assembly 34 extending about the power transmission module 22, a second light emitting assembly 36 extending about the first light emitting assembly 34, and a third light emitting assembly 38 extending about the second light emitting assembly 36. The light emitting assemblies 34, 36, and 38 form concentric rings about the power transmission module 22. As will be appreciated, each light emitting assembly may include one or more light sources (e.g., light emitting diodes, light bulbs, etc.) and/or a light guide to direct the light from the light sources to the show surface 21 of the center console 18. The light emitting assemblies may be configured to emit light at varying intensities, varying colors, and/or varying frequencies.
[0019] In certain embodiments, the controller 32 is configured to instruct each light emitting assembly to illuminate with increasing intensity to indicate alignment between the power transmission module and the power receiver module. For example, the light emitting assembly may be initially in a substantially darkened state. However, when the controller 32 detects alignment of the power modules, the controller 32 instructs the three light emitting assemblies to emit light of increasing intensity until a maximum light intensity is achieved. Accordingly, the vehicle occupant is provided with a visual indication of alignment between the power transmission module and the power receiver module.
[0020] The controller is also configured to instruct each light emitting assembly to illuminate in a sequential pattern to indicate power transfer from the power transmission module to the power receiver module. For example, the controller 32 may instruct the first light emitting assembly 34 to illuminate for a desired duration. After the desired duration has elapsed, the controller 32 may instruct the first light emitting assembly 34 to transition to a darkened state, and may instruct the second light emitting assembly 36 to illuminate for the desired duration. Similarly, after the desired duration has elapsed, the controller 32 may instruct the second light emitting assembly 36 to transition to a darkened state, and may instruct the third light emitting assembly 38 to illuminate the for the desired duration. The process may repeat to establish a "ripple effect" emanating from the portable electronic device 30 while the portable electronic device is charging.
[0021] The controller 32 is also configured to concurrently instruct each light emitting assembly to progressively cycle between an illuminated state and a darkened state to indicate that the portable electronic device is fully charged. For example, the controller 32 may instruct each light emitting assembly to emit light of gradually increasing intensity until a maximum intensity is reached. The controller 32 may then instruct each light emitting assembly to emit light of gradually decreasing intensity until a substantially darkened state is achieved. In this manner, the vehicle occupant is provided with a visual indication of the state of charge of the portable electronic device.
[0022] While the illustrated embodiment includes three concentric light emitting assemblies, it should be appreciated that more or fewer light emitting assemblies may be employed in alternative embodiments. In addition, it should be appreciated that the light emitting assemblies may be arranged in other patterns in alternative embodiments. Furthermore, the controller 32 may be configured to instruct the light emitting assemblies to illuminate in other patterns in alternative embodiments.
[0023] In the illustrated embodiment, the wireless charging indictor 26 includes an audio output device 40 communicatively coupled to the controller. The audio output device 40 is configured to provide an audible indication of alignment between the power transmission module and the power receiver module, to provide an audible indication of power transfer from the power transmission module to the power receiver module, and/or to provide an audible indication of a state of charge of the portable electronic device. As will be appreciated, the audio output device may include a speaker and/or an amplifier. In addition, it should be appreciated that the audible indication may be provided in conjunction with a visual and/or a haptic indication.
[0024] In the illustrated embodiment, the wireless charging indictor 26 includes a haptic output device 42 communicatively coupled to the controller. The haptic output device 42 is configured to provide a haptic indication of alignment between the power transmission module and the power receiver module, to provide a haptic indication of power transfer from the power transmission module to the power receiver module, and/or to provide a haptic indication of a state of charge of the portable electronic device. As will be appreciated, the haptic output device may include an eccentric mass shaker, for example. In addition, it should be appreciated that the haptic indication may be provided in conjunction with a visual and/or an audible indication.
[0025] FIG. 4 is a block diagram of an alternative embodiment of a wireless charging system having a wireless charging indicator. In the illustrated embodiment, the wireless charging indictor 26 includes four light emitting assemblies 44, 46, 48, and 50 arranged in a linear pattern. Similar to the light emitting assemblies described above with reference to FIG. 3, the light emitting assemblies are configured to provide a visual indication of power module alignment, power transfer, and/or state of charge. In certain embodiments, the first light emitting assembly 44 may illuminate when the power transmission module is aligned with the power receiver module, the second light emitting assembly 46 may illuminate to indicating that the portable electronic device is charging, the third light emitting assembly 48 may illuminate to indicate that the portable electronic device is fully charged, and the fourth light emitting assembly 50 may illuminate to indicate a fault condition, such as the portable electronic device not being compatible with the wireless charging system.
[0026] Each light emitting assembly (e.g., the light emitting assemblies described above with reference to FIGS. 3-4) may include a light source positioned beneath the show surface 21 of the center console 18, thereby illuminating a respective region of the show surface when activated. In certain embodiments, each respective region may appear dark (e.g., the same color as the remainder of the show surface) until the light emitting assembly is activated. While four light emitting assemblies are included in the illustrated embodiment, it should be appreciated that more or fewer light emitting assemblies may be employed in alternative embodiments. The light emitting assemblies may also convey information regarding wireless charging of the portable electronic device to a vehicle occupant by varying the intensity, varying the color, and/or varying the frequency of light emitted by each light emitting assembly.
[0027] While only certain features and embodiments of the invention have been illustrated and described, many modifications and changes may occur to those skilled in the art (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters (e.g., temperatures, pressures, etc.), mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter recited in the claims. The order or sequence of any process or method steps may be varied or re- sequenced according to alternative embodiments. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention. Furthermore, in an effort to provide a concise description of the exemplary embodiments, all features of an actual implementation may not have been described (i.e., those unrelated to the presently contemplated best mode of carrying out the invention, or those unrelated to enabling the claimed invention). It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation specific decisions may be made. Such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure, without undue experimentation.
