Title: Wireless charging service system

Description:
BACKGROUND OF THE INVENTION 
     (a) Technical Field of the Invention 
     The present invention generally relates to wireless charging, and more particularly to a system providing wireless charging and information services. 
     (b) Description of the Prior Art 
     The R.O.C. Taiwan Patent No. M525019, titled “Power supplying device and power receiving device of wireless charging system and charge controller thereof,” teaches a power receiving device of a wireless charging system for performing a method of selectively wireless charging. The device includes a processor and a storage unit. The storage unit stores a program which instructs the processor to perform the following steps: searching for a broadcast signal delivered by a power supplying device of the wireless charging system; determining a distance between the power supplying device and the power receiving device according to a strength of the broadcast signal when the broadcast signal is detected; when the distance is smaller than a threshold value, the power receiving device selecting the power supplying device and establishing connection with the power supplying device, and notifying the power supplying device that the power receiving device needs to be charged; and starting to receive power from the power supplying device when the power receiving device is determined to have a charging authorization by the power supplying device. According to the teaching, the power supplying device is able to push information to the power receiving device while the latter is wireless charged. However, a single piece of information is pushed and the information content does not vary, for example, according to the distance between the power supplying and receiving devices, or by remote control in real time. The teaching&#39;s applicability is therefore limited. 
     SUMMARY OF THE INVENTION 
     A major objective of the present invention is have a wireless charging device capable of dynamically transmitting different messages to a mobile device entering the coverage of the wireless charging device so as to achieve enhanced real-time information broadcast. 
     Another major objective of the present invention is to detect the proximity of the mobile device by a Bluetooth control element so that, when the mobile device is adjacent to the wireless charging device, wireless charging to the mobile device is activated. In the meantime, different messages are delivered to the mobile device under charging. 
     Yet another objective of the present invention is to have a service device data-linked with the wireless charging device so that different messages may be prepared on a remote cloud service and then relayed to the wireless charging device through the server device. As such, the real-time information broadcast may be more flexible and diversified. The wireless charging device may also be remotely activated or deactivated by through the server device. 
     To achieve the objectives, the wireless charging service system mainly includes a wireless charging device. The wireless charging device includes a data transceiver module, a wireless charging module, and a detection module. The data transceiver module is capable of transmitting one of a number of info messages. The wireless charging module wirelessly charges a mobile device, The Bluetooth control element of the detection module detects whether the mobile device is placed on the wireless charging device and activates/deactivates the wireless charging module. The wireless charging service system further includes a server device data-linked with the data transceiver module of the wireless charging device for sending info messages. The server device is data-linked with a remote cloud service. As such, when the mobile device enters a coverage of the data transceiver module, the mobile device receives an info message and presents the info message on the mobile device&#39;s screen. If the mobile device is placed on the wireless charging device for charging, the Bluetooth control element detects the proximity of the mobile device and activates the wireless charging device to start charging. In the meantime, the data transceiver module selects a different info message to transmit. The mobile device therefore may obtain different information based on its activities. 
     The content of info messages or additional info messages may be edited or created by the remote cloud service. The info messages are relayed to the wireless charging device through the server device. 
     Even though the prior art may also conduct wireless charging and information broadcast, only a single message may be transmitted and the content of the message cannot be changed when the mobile device is at different distances from the wireless charging device. The message content also cannot be modified remotely, which is quite inconvenient and troublesome. The present invention as described above resolves these issues effectively. 
     The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings, identical reference numerals refer to identical or similar parts. 
     Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
