All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Example 1:

the embodiment of the invention provides a wireless charging method and device, which can realize wireless charging for at least one mobile terminal such as a portable computer, a tablet computer, a smart phone and a mobile power supply through a micro base station. The following illustrates an application environment of the wireless charging method and apparatus.

Fig. 1 is a schematic diagram of an application environment of a wireless charging system according to an embodiment of the present invention; fig. 1(a), 1(b), 1(c) and 1(d) illustrate an application scenario for wirelessly charging at least one mobile terminal 20 through a micro base station 10, wherein the application scenario may further include a user (not shown in the figure).

In the embodiment of the present invention, the user enters a coverage range where the micro base station 10 generates the wireless charging signal with the at least one mobile terminal 20, and the micro base station 10 sends a broadcast message requesting an id code to the at least one mobile terminal 20; after receiving the broadcast message from the micro base station 10, the at least one mobile terminal 20 sends its identification code to the micro base station 10; the micro base station 10 compares the identification code with an identification code in a database, and verifies the identity of the at least one mobile terminal 20 to determine the charging authority of the at least one mobile terminal 20; according to the charging right, the micro base station 10 sends a security code to the at least one mobile terminal 20. In some embodiments, the micro base station 10 may further send an audit failed message to the at least one mobile terminal 20, that is, the micro base station 10 sends a security code to a mobile terminal with charging authority (authenticated) to allow it to perform wireless charging; and sending an auditing failure message to the mobile terminal without charging authority (failing to pass identity verification) to prevent the mobile terminal from performing wireless charging.

Wherein, in the process of verifying the identity of the at least one mobile terminal 20, the micro base station 10 and the at least one mobile terminal 20 may transmit required information using RFID. RFID (Radio frequency identification) belongs to an automatic identification technology that does not require direct contact. The RFID sends radio frequency signals with space coupling and transmission characteristics through the tag and the reader-writer, and then automatically identifies the articles through wireless. The RFID has the characteristics of automatic reading, real-time display and high safety.

It should be noted that the information transmission performed when the identity of the at least one mobile terminal 20 is verified is not limited to the information required by RFID transmission, and in practical applications, the required information may be transmitted by using other suitable communication methods, such as infrared rays, as needed.

The micro base station 10 firstly converts a digital signal into an analog signal, and then adjusts the analog signal to a carrier frequency to generate a wireless charging signal; and then transmits the wireless charging signal to the at least one mobile terminal 20 having the charging right.

In this embodiment of the present invention, the micro base station 10 may send the wireless charging signal to the at least one mobile terminal 20 based on the maximum transmission power of the wireless charging signal; or measuring the relative distance between the micro base station 10 and the at least one mobile terminal 20, and adjusting the transmission power of the wireless charging signal according to the relative distance, wherein the micro base station 10 sends the charging wireless charging signal to the at least one mobile terminal 20; or acquiring the remaining power of each mobile terminal in the at least one mobile terminal 20, and adjusting the signal transmission power of the wireless charging signal according to the remaining power, so that the micro base station 10 sends the wireless charging signal to the at least one mobile terminal 20, so as to preferentially provide the mobile terminal with less remaining power with the power required for charging; or acquiring the charging efficiency of the at least one mobile terminal 20 in unit time, adjusting the signal transmission power of the wireless charging signal according to the charging efficiency, and sending the wireless charging signal to the at least one mobile terminal 20 by the micro base station 10. In some embodiments, the wireless charging signal may also be transmitted to the at least one mobile terminal 20 by other suitable means. For example, the wireless charging signal is transmitted according to the performance of each mobile terminal; or, after receiving the signal fed back by the at least one mobile terminal 20, the micro base station 10 measures an incoming wave direction and a distance, so as to determine the position of the at least one mobile terminal 20, and the micro base station 10 may adjust a main lobe direction of the signal transmitting the wireless charging signal, so as to align a maximum gain of the main lobe direction to the at least one mobile terminal 20, so as to maximize the charging efficiency of the at least one mobile terminal 20.

The process of adjusting the transmission power of the wireless charging signal and transmitting the wireless charging signal to the at least one mobile terminal according to the relative distance between the micro base station 10 and the at least one mobile terminal 20 specifically includes: adjusting the signal emission intensity of the wireless charging signal according to the relative distance between the micro base station 10 and the at least one mobile terminal 20, and setting the emission intensity to 3 gears: high emission intensity, medium emission intensity, and low emission intensity. When the relative distance is larger than a set distance threshold, adjusting the signal emission intensity of the wireless charging signal to be high emission intensity; when the relative distance is equal to a set distance threshold, adjusting the signal emission intensity of the wireless charging signal to be a medium emission intensity; and when the relative distance is smaller than a set distance threshold, adjusting the signal emission intensity of the wireless charging signal to be low emission intensity. In some embodiments, the emission intensity may also be set to other suitable number of steps, such as 4 or more.

In the embodiment of the present invention, in order to ensure that the micro base station 10 has enough energy to transmit the wireless charging signal to the at least one mobile terminal 20, the micro base station 10 needs to be powered on. The micro base station 10 may be powered on by a continuous current supplied by an external power source, or the micro base station 10 may be powered on by a charging module of the micro base station itself. In some embodiments, the micro base station 10 may also be powered up by other suitable means to provide the energy required for wireless charging signal transmission.

The at least one mobile terminal 20 receives the wireless charging signal sent by the micro base station 10, and decodes the wireless charging signal. In the process of receiving the wireless charging signal, since the propagation distance of the wireless charging signal sent by the micro base station 10 is short, the frequency of the signal is high, and the frequency of the at least one mobile terminal 20 is generally low, in order to enable the at least one mobile terminal 20 to receive the wireless charging signal with the corresponding frequency sent by the micro base station 10 in a longer distance, a wireless charging signal conversion interface needs to be arranged in the at least one mobile terminal 20 to transfer the wireless charging signal. And the wireless charging signal conversion interface frequency is the same as the wireless charging signal frequency.

In the embodiment of the present invention, the at least one mobile terminal 20 filters the received wireless charging signal, extracts signals near the center of the carrier frequency, and filters unwanted signals in the wireless charging signal.

Wherein, according to the relative distance, adjusting the transmission power of the wireless charging signal, and sending the wireless charging signal to the at least one mobile terminal specifically includes: according to the relative distance, adjusting the signal emission intensity of the wireless charging signal, and setting the emission intensity to be 3 gears: high, medium and low emission intensities; when the relative distance is greater than the set distance threshold, adjusting the signal emission intensity of the wireless charging signal to be high emission intensity, so that the wireless charging signal can still be received when the distance between the at least one mobile terminal and the micro base station is far, and the purpose of charging is achieved; when the relative distance is equal to a set distance threshold, adjusting the signal emission intensity of the wireless charging signal to be a medium emission intensity; and when the relative distance is less than the set distance threshold, adjusting the signal emission intensity of the wireless charging signal to be low emission intensity, so that when the at least one mobile terminal is close to the micro base station, the loss in the wireless charging signal propagation process is reduced, and more wireless charging signal energy is transmitted to the at least one mobile terminal.

For example, a mobile terminal far away from the micro base station has a large amount of remaining power, and if a wireless charging signal is transmitted using the maximum power, a large amount of generated power is consumed in a short time. In order to avoid excessive loss in the wireless charging signal propagation process, firstly, the micro base station is required to acquire the residual electric quantity of each mobile terminal, secondly, each mobile terminal is sequenced from small to large according to the residual electric quantity, the mobile terminal with the minimum relative distance of the residual electric quantity is determined, and finally, the gear for sending the transmission intensity of the wireless charging signal is determined according to the residual electric quantity.

In some embodiments, the micro base station may step up the transmission power of the wireless charging signal or decrease the transmission power in real time according to the charging efficiency of the at least one mobile terminal per unit time. The adjustment mode can be understood as a mode of dynamically adjusting power and improving wireless charging efficiency. For example, when there is a blockage in the wireless charging signal transmission process, although the transmission power of the wireless charging signal is high, the wireless charging efficiency is still low, and at this time, the signal transmission power of the wireless charging signal may be dynamically adjusted. If the charging efficiency of the at least one mobile terminal in unit time does not reach a rated charging efficiency value, stepping by one power step; and measuring the charging efficiency again, and if the charging efficiency is not reached, stepping again until the charging efficiency reaches a rated value. And if the transmitting power does not reach the maximum transmitting power, step length adjustment can be carried out.
