Because wireless charging, can reduce the wearing and tearing and the damage of hardware interface that charges, extension equipment's life can eliminate the mess of charging wire, makes desktop or space more clean and tidy pleasing to the eye.

In the wireless charging and transmitting device 100, the wireless charging and transmitting device 100 includes a controller 101, a charging light transmitting component 102 and a transmitting end positioning component 103; the transmitting end positioning component 103 is configured to determine positioning data of the wireless charging receiving device 200 within a target space range where the wireless charging transmitting device 100 is located, and send the positioning data to the controller 101; the controller 101 is used for controlling the charging light emitting assembly 102 to work according to the positioning data; the charging light emitting component 102 is configured to emit charging light to a direction in which the wireless charging receiving device 200 is located under the control of the controller 101, so that the wireless charging receiving device 200 charges with the charging light. Thus, when the electronic device provided with the wireless charging receiving device 200 is located in the target space range, the charging light can be utilized to perform wireless charging, that is, the electronic device does not need to be in close contact with or even closely attached to the transmitting end as in the related art, wireless charging can be realized, and flexibility of wireless charging of the electronic device is improved.

The procedure for determining positioning data is explained below.

In an alternative implementation, the transmitting end positioning component 103 comprises a first positioning component; the positioning data includes first positioning data determined by the first positioning component; the controller 101 is configured to determine location information of the wireless charging receiving device 200 according to the first positioning data, and control the charging light emitting component 102 to operate according to the location information.

Thus, by the first positioning component, the position of the wireless charging receiving device 200 relative to the wireless charging transmitting device 100 can be quickly determined.

In another alternative implementation, as shown in fig. 4, a schematic structural diagram of another wireless charging transmitting device 100 provided in an embodiment of the present application is shown. Wherein, the transmitting end positioning component 103 in the wireless charging transmitting device 100 comprises a first positioning component 103A and a second positioning component 103B; the positioning data includes first positioning data determined by the first positioning component 103A and second positioning data determined by the second positioning component 103B; the controller 101 is configured to determine location information of the wireless charging receiving device 200 according to the first location data and the second location data, and control the charging light emitting assembly 102 to operate according to the location information.

In this way, the position information of the charging receiving device is determined according to the two positioning data determined by the two positioning components, so that double calibration of the position is realized, and the position of the wireless charging receiving device 200 is accurately positioned.

In one embodiment, the first positioning component 103A is an ultra wideband technology based positioning base station; the first positioning component 103A is configured to communicate with the positioning tag based on the ultra wideband technology in the wireless charging receiving apparatus 200 based on the ultra wideband technology to determine first positioning data, and send the first positioning data to the controller 101. Correspondingly, the receiving end positioning component 202 is a positioning tag based on ultra wideband technology; the receiving end positioning component 202 is configured to communicate with an ultra-wideband technology-based positioning base station in the wireless charging transmitting device 100 based on the ultra-wideband technology, so that the positioning base station can determine the first positioning data of the wireless charging receiving device 200 in the target spatial range.

The Ultra Wideband technology is also called UWB technology, and is a technology for realizing accurate positioning by using high bandwidth radio signals, and may be applied to indoor environments, especially in positioning occasions where high precision and high reliability are required, the main advantages of UWB technology include: UWB can measure the distance between the target and the positioning base station in a very short time (nanosecond level), thereby realizing centimeter level positioning accuracy and high-accuracy positioning; and UWB generally has lower power consumption than other wireless location technologies, and is suitable for continuous operation over long periods of time. In addition, due to the characteristics of narrow pulse width and non-sine wave, UWB can effectively overcome multipath effect, and accurate positioning performance can be maintained even in a complex indoor environment; besides, the UWB adopts a unique coding mode and other security technologies, the security is higher, the system structure is simpler, and the UWB is easy to integrate into various devices and systems.

The basic principle of UWB positioning is that positioning base stations with known coordinates are arranged indoors and are equipped with positioning tags of UWB technology (e.g. with positioning tags on electronic devices). The positioning tag transmits pulses according to a certain frequency, and then ranges with surrounding base stations, so that the positioning function is realized.

In the embodiment of the present application, when the wireless charging receiving device 200 is in the target space range and the positioning tag works, the positioning base station in the wireless charging transmitting device 100 communicates with the positioning tag, and then the positioning base station can acquire the first position data of the positioning tag, and the first position data represents the position of the wireless charging receiving device 200.

In one embodiment, the second positioning component 103B is an image capturing component; the second positioning component 103B is configured to capture a spatial image of the target spatial range, and send the spatial image to the controller 101 as second positioning data.

Optionally, the image capturing component is a camera, and is not specifically limited herein.

The image recognition algorithm is preset in the controller 101, and image recognition processing can be performed on the space image, so that the position of the wireless charging receiving component in the target space is determined, and the position of the wireless charging receiving component is accurately determined by the auxiliary controller 101.

Optionally, the spatial range that can be photographed by the image photographing assembly covers the target spatial range.

In one implementation, the image capturing component is configured to capture a target space at predetermined intervals. Alternatively, the above-mentioned aerial image may be a captured image transmitted by the image capturing component newly acquired by the controller 101.

In another implementation, after the controller 101 receives the first positioning data sent by the first positioning component 103A, a start instruction is sent to the image capturing component, and after the image capturing component receives the start instruction, a spatial image is captured and sent to the controller 101. Alternatively, the image capturing assembly may automatically stop operation after capturing the aerial image. Thus, the power consumption of the image photographing device can be effectively saved.

In another implementation, the image capturing component is a monitoring camera that continuously captures video of the target spatial range. The controller 101 may use the current latest video frame or frames in the video stream as the second positioning data after determining the first positioning data.

In one embodiment, the controller 101 is configured to determine, according to the first positioning data, first position data of the wireless charging receiving device 200 relative to the wireless charging transmitting device 100, and perform image recognition processing on the second positioning data, to obtain second position data of the wireless charging receiving device 200 in the target space range; and further determining location information based on the first location data and the second location data.

Taking the first positioning component 103A as an example of a positioning base station, correspondingly, after the controller 101 obtains and analyzes the first positioning data, the actual distance and the azimuth of the wireless charging receiving device 200 relative to the wireless charging transmitting device 100 can be determined, and optionally, the azimuth can be represented by an angle. Thus, the first location data may include a distance and a position of the wireless charging receiving device 200 relative to the wireless charging transmitting device 100.

Taking the second positioning component 103B as an image capturing component as an example, the second positioning data is a spatial image. The controller 101 is preset with an image recognition algorithm, the controller 101 performs image recognition processing on the spatial image by using the image recognition algorithm, so as to recognize the position of the wireless charging receiving device 200 in the spatial image, and because the position of the second positioning component 103B is fixed, the controller 101 can determine second position data based on the position of the wireless charging receiving device 200 in the spatial image, the position of the second positioning component 103B, and the position of the wireless charging transmitting device 100 in the target spatial range, where the second position data characterizes the position of the wireless charging receiving device 200 in the target spatial range.

Furthermore, the controller 101 performs calibration and comparison on the positions of the wireless charging receiving device 200 represented by the first position data and the second position data, so as to determine whether the positions of the wireless charging receiving device 200 indicated by the two position data are consistent, and determine position information if the positions are consistent, so that the charging light emitting assembly 102 is controlled to work by using the position information.

In one embodiment, the controller 101 is configured to compare the first position data with the second position data, and if a data error between the second position data and the second position data is less than a preset error threshold, use one of the second position data and the second position data as the position information.

Optionally, the controller 101 may perform data conversion on the first location data and the second location data, thereby converting the first location data and the second location data into the same data format that characterizes the location of the wireless charging receiving device 200, so as to calibrate and compare the first location data and the second location data.

The controller 101 is configured to compare the first position data and the second position data, and determine a data error therebetween, where the data error may represent an error between a position of the wireless charging receiving device 200 in the target spatial range or a position of the wireless charging receiving device 200 relative to the wireless charging transmitting device 100 indicated by the first position data and the second position data.

The controller 101 is preset with a preset error threshold value, compares the data error with the preset error threshold value, if the data error is smaller than the preset error threshold value, the error between the first position data and the second position data is smaller, the calibration and comparison of the first position data and the second position data are consistent, and one of the second position data and the second position data is used as position information.

Optionally, if the data error is not less than the preset error threshold, this means that the error between the first position data and the second position data is larger, and there may be a problem that the first positioning component 103A fails or the second positioning component 103B fails, so that the error is larger, and at this time, the controller 101 may output an abnormal reminding message, where the abnormal reminding message is used to instruct the user to perform fault detection on the wireless charging transmitting device 100.

In the embodiment of the present application, two sets of position data are determined based on the first positioning component 103A and the second positioning component 103B, and then the position information of the wireless charging receiving component is accurately determined through calibration and comparison of the two sets of position data, so as to ensure that the charging light is accurately transmitted to the wireless charging receiving component.

In one embodiment, the controller 101 is configured to determine a transmitting direction of the charging light transmitting assembly 102 according to the location information, and control the charging light transmitting assembly 102 to transmit the charging light based on the transmitting direction.

Optionally, in addition to the emission direction, the FOV (Field of View) of the charging light emitting element 102 is determined according to the position information, thereby controlling the charging light emitting element 102 to emit the charging light based on the emission direction and the View angle.

In one embodiment, the charged light emitting assembly 102 is a laser emitter.

Alternatively, the laser transmitter may be a power tunable laser for specific wavelength charging. In other words, the wavelength of the laser light emitted by the laser is adjustable, thereby changing the charging power of the wireless charging reception device 200.

Optionally, the charging light emitting component 102 may include a plurality of lasers with different wavelength ranges as laser sources, so as to expand the charging spectrum and increase the adjustment range of the charging power.

In the embodiment of the present application, the charging light emitting component 102 is a laser emitter, and since the laser emitter is different from sunlight, it is not affected by weather, and can ensure that the wireless charging receiving device 200 receives sufficient light energy and ensures charging speed in cloudy days or under insufficient illumination.

In one embodiment, the controller 101 is further configured to perform a human sensitive part identification process based on the second positioning data, and control the charging light emitting component 102 to stop working when the identification result indicates that the coverage area of the charging light has a human sensitive part.

Optionally, the sensitive parts of the human body refer to the positions of eyes, face and the like of the human body.

Illustratively, as described above, the second positioning component 103B continuously shoots a video of the target space range, and in the process of controlling the charging light emitting component 102 to emit the charging light, the controller 101 continuously acquires a new video frame shot by the second positioning component 103B, and performs the human sensitive part identification processing on the video frame, so as to determine whether the coverage area of the charging light has a human sensitive part in the process of emitting the charging light.

In one implementation, if a sensitive portion of the human body is present, the controller 101 controls the charging light emitting assembly 102 to stop operating until the sensitive portion of the human body leaves the coverage area of the charging light, and then controls the charging light emitting assembly 102 to continue operating.

In another implementation, the regulation specifies the radiation limit of the laser irradiating the human body, the controller 101 determines the first time according to the radiation limit specified by the regulation and the time that the sensitive part of the human body stays in the coverage area of the charging light, and controls the time that the charging light emitting assembly 102 stops working to be the first time, and after the first time, the charging light emitting assembly 102 is controlled again to continue working. It should be noted that, in the subsequent continuous operation process, the controller 101 still continues to determine the second duration according to the radiation limit specified by the rule and the duration that the sensitive part of the human body stays in the coverage area of the charging light, and controls the duration that the charging light emitting component 102 stops operating to be the second duration, and after the second duration, the charging light emitting component 102 is controlled to continue operating again, so as to avoid exceeding the rule.

Thus, by controlling the charging light emitting device to stop operating at a proper time, the human body can be prevented from being injured by the laser light, and the charging efficiency of the wireless charging receiving device 200 can be ensured.

In one aspect, when the wavelength of the charging light is different, the conversion power of the charging light conversion component 201 for converting the light energy into the electric energy is different, and the conversion power is related to the charging power for charging the component to be charged. On the other hand, taking the component to be charged as a battery in an electronic device, the electronic device generally charges the battery according to a preset charging curve, where the charging power required by the battery is different in different charging stages.

Based on this, in the embodiment of the present application, the receiving-end wireless communication component 203 in the wireless charging receiving device 200 is configured to obtain charging data, where the charging data includes, for example, at least the charging power currently required by the component to be charged. Optionally, the charging data may also include the charging current intensity or the like currently required by the component to be charged.

The receiving-side wireless communication module 203 transmits the acquired charging data to the transmitting-side wireless communication module 104, and the transmitting-side wireless communication module 104 transmits the charging data to the controller 101. The controller 101 determines the target wavelength from the charging data.

Taking charging data as charging power currently required by the component to be charged as an example, a plurality of sets of corresponding relations between candidate charging power and candidate wavelengths are pre-stored in the controller 101, and the controller 101 determines the candidate wavelength corresponding to the charging power currently required by the component to be charged according to the plurality of sets of corresponding relations, and the determined candidate wavelength is used as a target wavelength, so as to control the charging light emitting component 102 to emit charging light with the wavelength being the target wavelength, and thus, when the charging light converting component 201 receives the charging light with the target wavelength, the conversion power corresponds to the charging power currently required by the component to be charged, thereby ensuring that the charging power of the component to be charged is a required value, and effectively improving the charging efficiency of the component to be charged.

Alternatively, the receiving-end wireless communication module 203 and the transmitting-end wireless communication module 104 may be bluetooth communication modules, and bluetooth communication is performed after the two bluetooth communication modules are connected. Or the wireless communication component 203 and the transmitting wireless communication component 104 may be communication components that implement lan communication, both of which communicate based on the same lan. And is specifically defined herein.

Optionally, the peak operating wavelength of the constituent materials of the optical charging film is matched with the wavelength of the charging light; for example, the wavelength of the charging light emitted by the laser emitter may reach the peak operating wavelength.

Optionally, the optical charging film converts light energy into electrical energy at a conversion power that meets the target conversion requirement. The target conversion requirement may refer to the conversion power matching the charging power required by the component to be charged, for example, the conversion power being equal to or greater than the charging power required by the component to be charged.

Referring to fig. 7, there is shown a correspondence between the wavelength of the optically charged thin film and the converted power per unit area, with the peak operating wavelength lying between 500 and 600 nanometers.

In the embodiment of the application, the optical charging film with proper area and proper material is used as the photoelectric conversion component, so that the optical energy can be converted into electric energy, and the ideal charging power is further achieved. In addition, the optical charging film can reduce the occupied area of the charging light conversion assembly 201 in the electronic equipment and save the internal space of the electronic equipment.

In addition, as described above, the controller 101 may output the abnormality alert information, and optionally, the controller 101 may output the abnormality alert information to the receiving end wireless communication component 203 in the wireless charging receiving apparatus 200 by using the transmitting end wireless communication component 104, and the receiving end wireless communication component 203 sends the abnormality alert information to the electronic device, and the electronic device displays the abnormality alert information for the user to view, thereby implementing the alert function.
