A method to improve the efficiency of wireless charging

Abstract

The invention discloses a method for improving wireless charging efficiency. The wireless charging device has a control module, a wireless charging coil connected to the control module, an automatic coil driving unit, and a charging efficiency related parameter detection module; the displacement stroke of the wireless charging coil is the first Between the limit position and the second limit position, the initial position is the first limit position or the second limit position; after placing the product to be charged, the coil automatic drive unit first moves forward to drive the wireless charging coil to move to the initial position along the positive direction. The charging efficiency related parameter detection module first detects the related parameters of the current position, and then the coil automatic drive unit reverses to drive the wireless charging coil to gradually move in the reverse direction. After each step of displacement, the related parameters are detected, and the related parameters are compared step by step to obtain The highest charging efficiency position keeps the wireless charging coil at this position; effectively ensures the adjustment accuracy of the wireless charging coil, its algorithm is relatively simple, and the electronic control operation is reliable.

Description

technical field [0001] The invention relates to the technology in the field of brackets, in particular to a method for improving wireless charging efficiency. Background technique [0002] The traditional wireless charging bracket can meet the clamping positioning and wireless charging of mobile phones and other electronic products. In actual use, due to the variety of brands, models, and sizes of mobile phones and other electronic products, the position of the receiving coil in these electronic products They are also different, so when different electronic products are charged on the same wireless charging stand, the charging coil and receiving coil cannot be aligned, making it difficult to achieve optimal charging efficiency. [0003] Later, someone proposed to move the wireless charging coil inside the wireless charging bracket to align with the position of the receiving coil in the electronic product, thereby effectively improving the charging efficiency. However, the e...

AI Technical Summary

Problems solved by technology

[0004] 1. In the existing technology, although the wireless charging coil can be moved, its adjustment accuracy is not good, and it is difficult to adjust to the ideal charging efficiency in actual adjustment; in addition, the algorithm is complicated when adjusting the wireless charging coil, and the electronic control part Prone to disorder, high failure rate;

[0005] 2. Use the motor to drive the displacement of the wireless charging coil. After moving the wireless charging coil to the position with the highest charging efficiency, the motor still needs to be powered on to maintain the working state to maintain the position of the wireless charging coil. Otherwise, the wireless charging coil will fall off. (Place it vertically, due to gravity); in this way, it will consume a lot of power, and at the same time, the performance of the motor will be negatively affected if it is used for a long time;

[0006] 3. The design of the mobile control structure of the wireless charging coil is unreasonable. It occupies a large space in the wireless charging bracket, which is not conducive to the design and layout of other components of the wireless charging bracket, and increases the difficulty of designing and manufacturing the wireless charging bracket. At the same time, It also limits the miniaturization design of the entire wireless charging stand

[0007] 3. The smoothness and accuracy of the mobile control of the wireless charging coil are not ideal, which affects the reliability of the wireless charging bracket.
