Description

CABLELESS MOBILE ENERGY SOURCE

FIELD OF INVENTION

The present invention here relates to the field of mobile energy source for wireless charging of mobile communication devices, and more particularly, it is directed at a mobile energy source which is cableless, mobile and portable to be transported around, with the ability to store energy to wirelessly charge mobile communication devices like mobile smart-phones, mobile electronic tablet computers, mobile game consoles and other similar mobile devices by just attaching onto the back casing of such mobile devices. The cableless mobile energy source itself would need to be charged and can be adapted for use in many different countries which have different electrical voltages and frequency requirements, hence eliminating the need to carry a separate travel adapter and/or charger. In addition, the cableless mobile energy source eliminates the use of conventional electrical power wall socket and can be used universally anywhere across different countries / regions.

BACKGROUND OF THE INVEN11ON

With globalisation, more and more people are travelling overseas to different countries and/or regions for business and/or leisure and the proliferation of mobile communication devices like mobile smart-phones, mobile electronic tablet computers etc has led to an increase in power consumption needed to power-up such mobile devices. Different countries have different electrical voltage and frequency requirements and the need to carry a separate travel adaptor and/or charger still exists.

A general common feature with travel adaptor is that most of the travel adaptor has some form of wire cable attached to it, with one side of the travel adaptor having the conventional plug and/or pins that is interfacing with the A.C. wall socket found in the respective country and/or region, and the other side of the travel adaptor having matching holes or sockets that is interfacing with the charging plug of the mobile device.

Typical travel adaptors have a certain thickness at the plug-side and can be quite troublesome and bulky for a user to carry around at times when travelling overseas.

The present invention here serves to disclose a cableless mobile energy source for charging of mobile communication devices, with the intention to be used universally anywhere the user travels, hence replacing the need to use conventional travel adaptor and eliminating the need for a conventional electrical power wall socket.

Currently in the market, there are already some mobile communication devices that are able to be wirelessly charged up. With the proliferation of mobile communication devices, there will be more of such devices coming up in the future which can be wirelessly charged by embedding compatible magnetic coils and circuitry, i.e. the receiver modules necessary to deliver electricity to the devices' batteries. The wireless charging technology adopted in the present invention is the conventional inductive charging method via the use of electromagnetic field. An example is the Qi inductive power standard that is developed by the Wireless Power Consortium (http://www.wirelesspowerconsortium.com). The cableless mobile energy source is mobile and portable to carry around, eliminating the need for a conventional electrical power wall socket. The cableless mobile energy source can be implemented in most indoor places, like for example in future "intelligent" or smart homes, offices, hotel rooms, meeting and function rooms, cafes and restaurants, etc. Thus the advantages of the cableless mobile energy source are: 1. Cableless or cable-free; 2. Less messy & hassle-free for the user since there are no cables lying around; 3. Mobile and portable to carry around due to its small mobile size; 4. Ability to adapt to different electrical voltages and frequencies, thus making it usable universally and globally across countries/regions.

The embodiment disclosed in the present invention involves having at least one (1) transmitter module and one (1) receiver/transmitter module embedded with circuitry that is able to detect and automatically switch between a receiver mode and a transmitter mode depending on its intended usage at that point of time. The transmitter module eliminates the need for a typical conventional electrical power wall socket. The transmitter module has the necessary circuitry to regulate the different electrical voltages and frequencies so as to suit the voltage I frequency requirement needed by the mobile communication devices. The transmitter module is affixed to the wall in the same manner in which a typical conventional electrical power wall socket is installed. The receiver/transmitter module is the module that is being used to irelessly charge up mobile communication devices by attaching to the back casing of such mobile devices.

This means that the receiver/transmitter module acts like a battery and is able to store energy. The mobile communication devices are embedded vvith the receiver module.

Upon detecting the contact with the back casing of such mobile devices, the receiver/transmitter module is able to automatically switch over to a transmitter mode so as to transmit and charge the mobile devices embedded with the receiver modules.

There is an indicator light on the panel of the receiver/transmitter module to indicate the current status of the energy stored inside the receiver/transmitter module. Hence during charging of the mobile device, the indicator light will indicate the amount of energy left inside the receiver/transmitter module before the user would need to recharge the receiver/transmitter module for subsequent usage. As mentioned earlier, the wireless charging process is the conventional inductive charging method via the use of electromagnetic field. To recharge or to store up the energy, the receiver/transmitter module would need to be magnetically attached to the transmitter module that is affixed to the wall. Under the recharged mode, the circuitry within the receiver/transmitter module would then be able to sense and detect the contact point with the transmitter module affixed to the wall, thus automatically switches itself to a receiver mode to receive the charged energy from the transmitter module. There is an indicator light on the panel of the receiver/transmitter module to highlight the charging status of the receiver/transmitter module. Hence the entire charging and discharging process is then repeated.

The technology behind the attachment of the receiver/transmitter module to the back casing of the mobile devices can be implemented by licensing technologies such as nanoscopic suction surface-like technologies patented by UM! Brands (httrx//wvvw.um brands.com/) or via the use of other similar releasable pressure sensitive materials that is available in the market which are licensable as well.

The present invention also incorporates another embodiment whereby there is an extension device to support multiple charging of the receiver/transmitter module at any one time. The extension device would need to have the necessary circuitry in order to support multiple charging of the receiver/transmitter module. Moreover the extension device is embedded with the necessary circuitry to regulate the different electrical voltages and frequencies so as to suit the voltage / frequency requirement needed by the mobile communication devices Each receiver/transmitter module can be customizable with different energy capacities to cater to different battery capacities of different mobile communication devices. It can be customized ranging from one (1) to a maximum of five (5) receiver/transmitter modules at any one time.

Both the transmitter module and the receiver/transmitter module can be injection-molded using high-grade polymeric materials that are able to withstand the continuing usage stresses as well as the charging/discharging processes that come with repeated usage.

Like in all other conventional electrical charging devices, the cableless mobile energy source would need to undergo other tests like the CE and other electrical safety related tests.

The present invention here relates to the field of mobile energy source for wireless charging of mobile communication devices, and more particularly, it is directed at a mobile energy source which is cableless, mobile and portable to be transported around, with the ability to store energy to wirelessly charge mobile communication devices like mobile smart-phones, mobile electronic tablet computers, mobile game consoles and other similar mobile devices by just attaching onto the back casing of such mobile devices.

Figure 1 illustrates a perspective view of the embodiment of the present invention, which consists of the transmitter module and the receiver I transmitter module. It consists of the transmitter module I that is affixed to any wall of a typical building structure, as well as a receiver/transmitter module 2 that can be magnetically attached to the transmitter module 1 so as to recharge the receiver/transmitter module 2 as the receiver/transmitter module 2 acts like a battery and is able to store energy. The receiver/transmitter module 2 has the ability to automatically switch between being a receiver or as a transmitter.

During the recharge mode, the embedded circuitry within the receiver/transmitter module 2 will switch to being on a receiver mode once it is able to sense that contact point has been made with the transmitter module 1 that is affixed to the wall. There is a lighting indicator 3 on the panel of the receiver/transmitter module 2 to highlight the charging status of the receiver/transmitter module 2.

Figure 2 illustrates a perspective view of the embodiment of the present invention which highlights the receiver/transmitter module 2 magnetically attached to the transmitter module 1. During charging, the lighting indicator 3 on the panel of the receiver/transmitter module 2 would be able to highlight the charging status of the module 2.

Figure 3 illustrates a perspective view of another embodiment of the present invention with an extension device 4 catering to multiple charging of up to a maximum of five (5) receiver / transmitter modules. The extension device 4 would need to have the necessary circuitry in order to support multiple charging of the receiver/transmitter module since it acts like a battery and is able to store energy. Moreover the extension device is embedded with the necessary circuitry to regulate the different electrical voltages and frequencies so as to suit the voltage / frequency requirement needed by the mobile communication devices. Similarly, the transmitter module has the necessary circuitry to regulate the different electrical voltages and frequencies so as to suit the voltage / frequency requirement needed by the mobile communication devices. Each receiver/transmitter module 2 can be customizable with different energy capacities to cater to different battery capacities of different mobile communication devices.

Assuming that there are more than one (1) receiver/transmitter module 2 charging at the same time, the extension device 4 is also intelligent enough to stop charging one of the receiver/transmitter module 2 at any one time once it has reached full charge.

Figure 4A illustrates a perspective view of the extension device 4, the transmitter module I itself and one (1) of the receiver / transmitter module 2. The receiver/transmitter module 2 can be attached magnetically to the extension device 4, and the extension device 4 can then be magnetically attached to the transmitter module 1. This is further illustrated in Figure 4B, whereby Figure 4B illustrates a perspective view of the single one (1) receiver / transmitter module 2 being attached magnetically to the extension device 4. The lighting indicator 3 highlights the charging status of the receiver/transmitter module 2 when the extension device 4 is attached magnetically to the transmitter module 1. This is further illustrated in Figure 4C, wherein it illustrates a perspective view of the charging of the single one (1) receiver / transmitter module 2 when it is attached magnetically to the extension device 4.

Figure 5 illustrates how the embodiment of the present invention can be applied onto mobile communication devices like smart phone 5. Besides smart phones, other mobile communication devices include mobile electronic tablets, game consoles, etc. Each of these mobile communication devices are embedded with compatible magnetic colis and circuitry, i.e. the receiver modules necessary to deliver electricity to the devices' batteries. Upon detecting the contact with the back casing of such mobile devices, the receiver/transmitter module 2 is then on charging mode, and is thus able to automatically switch over to a transmitter mode so as to transmit and charge the mobile devices embedded with the receiver modules. Hence during charging of the mobile device, the lighting indicator 3 will indicate the amount of energy left inside the receiver/transmitter module 2 before the user would need to recharge the receiver/transmitter module 2 for subsequent usage. The technology behind the attachment of the receiver/transmitter module 2 to the back casing of the mobile devices can be implemented by licensing technologies such as nanoscopic suction surface-like technologies patented by UM! Brands (http:/Mww.um-brands.coml) or via the use of other similar releasable pressure sensitive materials that is available in the market which are licensable as well.
