[0040] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.
[0041] The following is attached to the instruction manual Figures 1 to 5 And embodiments 1 to 3 describe in detail the method, device and wireless charging device for automatically adjusting the wireless charging matching degree of the present invention.
[0042] Example 1
[0043] This embodiment describes in detail the method for automatically adjusting the wireless charging matching degree of the present invention.
[0044] Figure 1 FIG. 4 is a flow chart showing the method for automatically adjusting the wireless charging matching degree according to the present embodiment. Figure 1 As shown, the method for automatically adjusting the wireless charging matching degree in this embodiment includes the following steps:
[0045] S1: Obtain the location information of the wireless charging receiving end. After obtaining the location information of the wireless charging receiving end, this embodiment can quickly move the wireless charging transmitting end to the vicinity of the wireless charging receiving end, so that the wireless charging transmitting end and the wireless charging receiving end are at approximately the closest position to the best charging state. Specifically, when the wireless charging transmitting end and the wireless charging receiving end are not at approximately the closest position to the best charging state, the position of the wireless charging transmitting end is adjusted and the wireless charging transmitting end and the wireless charging receiving end are at approximately the closest position to the best charging state, so as to reduce the amplitude of the subsequent adjustment of the position of the wireless charging transmitting end and improve the efficiency of the subsequent matching of the wireless charging transmitting end and the wireless charging receiving end.
[0046] S2: Obtain the temperature information of the wireless charging transmitter, and determine whether the wireless charging transmitter is currently within a preset temperature range based on the obtained temperature information. Specifically, the preset temperature range is the temperature of the wireless charging transmitter when the wireless charging transmitter and the wireless charging receiver are in the best matching position; or the preset temperature range is the temperature when the wireless charging transmitter is at the highest charging efficiency; or the preset temperature range is the best temperature of the wireless charging transmitter during the charging process. By obtaining the temperature information of the wireless charging transmitter, and determining whether the wireless charging transmitter is currently within the preset temperature range based on the obtained temperature information, it can be determined whether the current wireless charging transmitter and the wireless charging receiver are in the best matching position. When the wireless charging transmitter is currently within the preset temperature range, it means that the current wireless charging transmitter and the wireless charging receiver are in the best matching position; conversely, when the wireless charging transmitter is not currently within the preset temperature range, it means that the current wireless charging transmitter and the wireless charging receiver are not in the best matching position.
[0047] S3: If the temperature of the wireless charging transmitter is not within the preset temperature range, the position of the wireless charging transmitter is adjusted based on the position information of the wireless charging receiver until the temperature of the wireless charging transmitter is within the preset temperature range. Specifically, the position of the wireless charging transmitter is continuously adjusted using a feedback mechanism until the temperature of the wireless charging transmitter is within the preset temperature range. For example, the position of the wireless charging transmitter can be adjusted once so that the wireless charging transmitter and the wireless charging receiver are in the best matching position; the position of the wireless charging transmitter can be adjusted twice so that the wireless charging transmitter and the wireless charging receiver are in the best matching position; or the position of the wireless charging transmitter can be adjusted three times or more so that the wireless charging transmitter and the wireless charging receiver are in the best matching position.
[0048] The method for automatically adjusting the wireless charging matching degree of this embodiment obtains the position information of the wireless charging receiving end, obtains the temperature information of the wireless charging transmitting end, and determines whether the wireless charging transmitting end is currently within the preset temperature range based on the obtained temperature information. If the temperature of the wireless charging transmitting end is not within the preset temperature range, the position of the wireless charging transmitting end is adjusted based on the position information of the wireless charging receiving end until the temperature of the wireless charging transmitting end is within the preset temperature range, so that the wireless charging transmitting end and the wireless charging receiving end are in the best matching position, which not only solves the problem of the fixed position of the wireless charging receiving end, but also reduces the energy loss of wireless charging, thereby improving the charging efficiency and charging stability of the wireless charging receiving end, reducing energy waste, reducing heat generation, protecting the wireless charging transmitting end and the wireless charging receiving end, and improving their performance and service life. Specifically, the method for automatically adjusting the wireless charging matching degree of this embodiment can increase the conversion efficiency of wireless charging by 10-30% and reduce the overall heating degree by 10-30%. That is, the method for automatically adjusting the wireless charging matching degree of this embodiment solves the technical problems of energy waste, low wireless charging efficiency, large amount of heat generation and poor charging stability in the wireless charging process of the prior art.
[0049] According to a preferred embodiment, the location information of the wireless charging receiving end is obtained in the following manner: a positioning system is provided on one of the wireless charging transmitting end and the wireless charging receiving end, and a detection and positioning device is provided on the other, the detection and positioning device matches the positioning system, and the detection and positioning device is used to detect the signal sent by the positioning system and obtain the location information of the wireless charging receiving end. Preferably, the positioning system is installed on the wireless charging receiving end, and the detection and positioning device is installed on the wireless charging transmitting end. The preferred technical solution of this embodiment can obtain the location information of the wireless charging receiving end by detecting the signal sent by the positioning system through the detection and positioning device, so that the wireless charging transmitting end can be moved to the vicinity of the wireless charging receiving end by the moving device on the wireless charging transmitting end, so that the wireless charging receiving end can be paired with the wireless charging transmitting end for charging.
[0050] According to a preferred embodiment, the positioning system includes a GPRS positioning system, an infrared positioning system or an ultrasonic positioning system; the detection and positioning device includes a GPRS positioning detection device, an infrared positioning detection device or an ultrasonic positioning detection device. For example, when the positioning system is an infrared positioning system, the detection and positioning device is an infrared positioning detection device, the positioning system emits an infrared signal, and after the detection and positioning device detects the infrared signal, the position of the wireless charging receiving end can be determined. The positioning system of the preferred technical solution of this embodiment is not limited to this, and can also be other positioning systems.
[0051] According to a preferred embodiment, obtaining the temperature information of the wireless charging transmitter includes: obtaining the temperature information of the coil on the wireless charging transmitter, and / or obtaining the temperature information of the PCB board on the wireless charging transmitter. Preferably, the temperature of the coil on the wireless charging transmitter is obtained in the following manner: a coil NTC resistor is provided on the coil of the wireless charging transmitter, and the temperature of the coil NTC resistor is detected by a temperature detection device or a temperature sensing package, and the temperature of the coil NTC resistor is used as the temperature of the coil on the wireless charging transmitter. Figure 2 As shown, the temperature detection device or temperature sensing package also sends the detected temperature of the coil NTC resistor to the main chip of the transmitter end, so as to determine whether the temperature of the coil on the current wireless charging transmitter end is the optimal temperature. The preferred technical solution of this embodiment utilizes a temperature detection device or a temperature sensing package to detect the temperature of the coil NTC resistor, and uses the temperature of the coil NTC resistor as the temperature of the coil on the wireless charging transmitter end. It can accurately detect the temperature of the coil during the wireless charging process, so as to accurately determine whether the wireless charging transmitter end is currently at the optimal temperature. Preferably, the temperature of the PCB board on the wireless charging transmitter end is obtained in the following manner: a chip NTC resistor is provided on the PCB board of the wireless charging transmitter end, and the temperature of the chip NTC resistor is detected by a temperature detection device or a temperature sensing package, and the temperature of the chip NTC resistor is used as the temperature of the PCB board on the wireless charging transmitter end. As shown in FIG. Figure 2 As shown, the temperature detection device or temperature sensing package also sends the detected temperature of the patch NTC resistor to the main chip of the transmitter to determine whether the temperature of the PCB board on the current wireless charging transmitter is the optimal temperature. The preferred technical solution of this embodiment uses the temperature detection device or temperature sensing package to detect the temperature of the patch NTC resistor, and uses the temperature of the patch NTC resistor as the temperature of the PCB board on the wireless charging transmitter, which can accurately detect the temperature of the PCB board during the wireless charging process, so as to accurately determine whether the wireless charging transmitter is currently at the optimal temperature. Figure 2 The transmission principle of the transmitting end is also shown, which will not be described in detail here.
[0052] According to a preferred embodiment, whether the wireless charging transmitter is currently at the optimal temperature is determined in the following manner: the detected coil temperature is compared with the preset coil temperature, and the detected coil temperature is within the preset coil temperature, and / or the detected PCB board temperature is compared with the preset PCB board temperature, and the detected PCB board temperature is within the preset PCB board temperature, then the wireless charging transmitter is currently at the optimal temperature. That is: the coil temperature and the PCB board temperature can be either within the preset temperature range, and the wireless charging transmitter is considered to be currently at the optimal temperature; or the coil temperature and the PCB board temperature need to be both within the preset temperature range, and then the wireless charging transmitter is considered to be currently at the optimal temperature. The preset coil temperature and the preset PCB board temperature are determined based on the current indoor ambient temperature and the charging parameters of the wireless charging transmitter. For example, the charging conversion rate of the wireless charging transmitter is 100%, that is, all the current signals transmitted by the wireless charging transmitter are received by the wireless charging receiving end. At this time, the preset coil temperature and the preset PCB board temperature can be set to be equivalent to or slightly higher than the indoor ambient temperature. If the detected coil temperature is not within the preset coil temperature, and / or the detected PCB board temperature is not within the preset PCB board temperature, it means that the wireless charging transmitter is not currently at the optimal temperature, and the charging conversion rate at this time is not the highest, and part of the energy is converted into heat energy, which means that the current wireless charging transmitter and the wireless charging device have not reached the best matching position; conversely, if the detected coil temperature is within the preset coil temperature, and / or the detected PCB board temperature is within the preset PCB board temperature, it means that the wireless charging transmitter is currently at the optimal temperature, and the charging conversion rate at this time is the highest, which means that the current wireless charging transmitter and the wireless charging device have reached the best matching position.
[0053] like Figure 3 As shown, adjusting the position of the wireless charging transmitter includes the following steps:
[0054] S301: Move the wireless charging transmitter forward, left, right and backward respectively, and record the charging parameters of the wireless charging transmitter in the four moving modes. Preferably, the charging parameters of the wireless charging transmitter are, for example, the charging efficiency and charging temperature of the wireless charging transmitter.
[0055] S302: Based on the recorded charging parameters of the wireless charging transmitter and the charging parameters of the wireless charging receiver in the four mobile modes fed back by the wireless charging receiver, determine whether the wireless charging transmitter and the wireless charging receiver have the best matching position in the four mobile modes. The charging parameters of the wireless charging receiver are, for example, the charging speed and charging temperature of the wireless charging receiver.
[0056] S303: When the wireless charging transmitter and the wireless charging receiver have the best matching position in the four moving modes, move the wireless charging transmitter to the best matching position.
[0057] Specifically, when the wireless charging transmitter has not reached the optimal temperature, the wireless charging transmitter is moved forward, left, right and backward respectively, and the charging parameters of the wireless charging transmitter in the four mobile modes are recorded. Based on the recorded charging parameters of the wireless charging transmitter and the charging parameters of the wireless charging receiver in the four mobile modes fed back by the wireless charging receiver, it is determined whether the wireless charging transmitter and the wireless charging receiver have the best matching position in the four mobile modes. When the charging parameters of the wireless charging transmitter and the charging parameters of the wireless charging transmitter are both within the preset optimal charging parameter range, it means that the mobile mode can make the wireless charging transmitter and the wireless charging receiver reach the best matching position; on the contrary, when one or two of the charging parameters of the wireless charging transmitter and the charging parameters of the wireless charging transmitter are not within the preset optimal charging parameter range, it means that the mobile mode cannot make the wireless charging transmitter and the wireless charging receiver reach the best matching position. If the wireless charging transmitter and the wireless charging receiver can have the best matching position in the four mobile modes of forward, left, right and backward, the wireless charging transmitter is moved to the best matching position in one of the moving modes of forward, left, right and backward.
[0058] More specifically, a charging detection device is installed on the wireless charging receiving end, which automatically detects the charging information and feeds it back to the transmitting end through protocol communication. The transmitting end determines which mobile mode has the best matching position by combining the charging parameters of the wireless charging transmitting end and the charging parameters of the wireless charging receiving end fed back by the wireless charging receiving end, and achieves the best matching position by fine-tuning the position of the wireless charging transmitting end.
[0059] The preferred technical solution of this embodiment jointly utilizes the charging parameters of the wireless charging transmitter and the charging parameters of the wireless charging receiving terminal fed back by the wireless charging receiving terminal to determine whether the current wireless charging transmitter and the wireless charging receiving terminal are in the best matching position, which can improve the accuracy of the judgment on the one hand, and on the other hand, it can also improve the sensitivity of the judgment. For example, when the wireless charging transmitter and the wireless charging receiving terminal are charging in the best matching position, if the position of the wireless charging receiving terminal and / or the wireless charging transmitter is accidentally moved, and the charging parameters of the wireless charging transmitter have not changed at this time, the change in the charging parameters of the wireless charging receiving terminal fed back can be used to determine that the current wireless charging transmitter and the wireless charging receiving terminal have deviated from the best matching position.
[0060] See again Figure 3 In the four mobile modes, when the wireless charging transmitter and the wireless charging receiver do not have the best matching position, the following steps are also included:
[0061] S304: based on the recorded charging parameters of the wireless charging transmitter and the charging parameters of the wireless charging receiver in the four mobile modes fed back by the wireless charging receiver, select one or two mobile modes in which the positions of the wireless charging transmitter and the wireless charging receiver have the highest matching degree among the four mobile modes;
[0062] S305: Move the wireless charging transmitter to adjacent directions of one or two moving modes with the highest matching degree between the positions of the wireless charging transmitter and the wireless charging receiver, and record charging parameters of the wireless charging transmitter in the two or four moving modes;
[0063] S306: Based on the recorded charging parameters of the wireless charging transmitter and the charging parameters of the wireless charging receiver in the two or four mobile modes fed back by the wireless charging receiver, determine the best matching position between the wireless charging transmitter and the wireless charging receiver in the two or four mobile modes, and move the wireless charging transmitter to the best matching position.
[0064] Specifically, when the four moving modes of forward, left, right and backward cannot make the wireless charging transmitter and the wireless charging receiver have the best matching position, first screen out which one or two of the four moving modes of forward, left, right and backward can make the charging parameters of the wireless charging transmitter and / or the charging parameters of the wireless charging receiver within the preset optimal charging parameter range, or which one or two modes can make the wireless charging transmitter and the wireless charging receiver have a better matching degree. For example, among the four moving modes, moving to the left can make the wireless charging transmitter and the wireless charging receiver have a better matching degree. At this time, continue to move the wireless charging transmitter to the upper left and lower left directions respectively, and record the charging parameters of the wireless charging transmitter in the two moving modes; then based on the recorded charging parameters of the wireless charging transmitter and the charging parameters of the wireless charging receiver in the two moving modes fed back by the wireless charging receiver, for example, it is determined that moving to the upper left can make the wireless charging transmitter and the wireless charging receiver reach the best matching position, and at this time, the wireless charging transmitter is moved to the upper left direction.
[0065] Furthermore, if the wireless charging transmitter and the wireless charging receiver still do not have the best match after moving to the front left, front right, rear left, and rear right directions, the above steps S304 to S306 can be repeated to continue moving the position of the wireless charging transmitter until the wireless charging transmitter and the wireless charging receiver have the best match after the movement. Through multiple adjustments, the accuracy of the best match between the wireless charging transmitter and the wireless charging receiver can be improved.
[0066] The method of automatically adjusting the wireless charging matching degree in this embodiment is mainly used for the wireless charging station of the smart home, which can achieve rapid positioning, precise control, and maintain the optimal charging state within a certain spatial range.

Figure 4 Preferably, the first acquisition module 101 is used to acquire the position information of the wireless charging receiving terminal; the second acquisition module 102 is used to acquire the temperature information of the wireless charging transmitting terminal, and judge whether the wireless charging transmitting terminal is currently within the preset temperature range based on the acquired temperature information; if the temperature of the wireless charging transmitting terminal is not within the preset temperature range, the adjustment module 103 is used to adjust the position of the wireless charging transmitting terminal based on the position information of the wireless charging receiving terminal until the temperature of the wireless charging transmitting terminal is within the preset temperature range.
[0070] The device for automatically adjusting the matching degree of wireless charging in this embodiment includes a first acquisition module 101, a second acquisition module 102 and an adjustment module 103. Through the functions of the first acquisition module 101, the second acquisition module 102 and the adjustment module 103, the wireless charging transmitter and the wireless charging receiver can be placed in the best matching position, which not only solves the problem of the fixed position of the wireless charging receiver, but also improves the charging efficiency and charging stability of the wireless charging receiver, reduces energy waste, and reduces heat generation, thereby protecting the wireless charging transmitter and the wireless charging receiver.
