Problems solved by technology

The early alignment technology used magnets, but most of them have been eliminated and changed to multi-coil matching. Although the alignment problem has been solved to a certain extent, there are still problems of large heat generation and complex structure. Therefore, a self-alignment technology is required. standard wireless power bank

specific Embodiment

[0031] When the device is placed on the touch sensor array 8 in a horizontal state, the measured coordinate values ​​of the four endpoints are: α=(4,14), β=(20,7), θ=(4,7), λ=( 20, 14), the calculation can get z=17.46, the path from point α to point β and the path from point θ to point λ are approximately equal to z, and both pass through the end point (13.11), which is the geometric center.

[0032] When the device is placed on the tactile sensor array 8 in an inclined state, the measured coordinate values ​​of the four endpoints are: α=(7,18), β=(17,4), θ=(4,12), λ=( 20, 10), the calculation can get x1=13, y1=8, z1=15.26; x2=4, y2=6, z2=7.21; then z3=16.88; the path from α point to β point and from θ point to The path of point λ is approximately equal to z3, and both pass through the endpoint (12, 11), which is the geometric center.

[0033] Components not specified herein are prior art.

Abstract

The invention relates to a self-aligning wireless charging treasure for mobile equipment and an alignment method. The technical solution adopted is: including shell, lithium battery, wireless charging coil, power indicator, wireless charging switch, USB charging interface, power detection circuit, tactile sensor array, horizontal chute, vertical chute, vertical moving arm, horizontal Moving arm, support rod, transmission line, sampling scanning circuit, data acquisition chip, STM32 microcontroller, sliding module. The invention uses the tactile sensor array to probe the shape of the contact surface between the device and the wireless charging treasure, uses the matrix to calculate the geometric center of the contact surface, and controls the stepping motor in the chutes around the device to move the wireless charging coil to the geometric center position and start charging after alignment. ;Although there is a certain error, as the tactile sensor unit continues to develop, the alignment will be further accurate.

Description

technical field [0001] The invention belongs to the field of wireless charging devices, and relates to a self-aligning wireless charging treasure for mobile devices and an alignment method. Background technique [0002] With the continuous development of charging treasure technology, wireless charging treasure has become an indispensable backup energy. However, due to the technical characteristics of the power bank, it is necessary to align the wireless charging coil with the receiving coil in the device during charging to ensure maximum power charging, and the receiving coil on mobile devices is usually installed in the middle of the back, so if it is not aligned, On the one hand, the charging speed is slow, and on the other hand, the coil heats up violently, which consumes most of the energy. The early alignment technology used magnets, but most of them have been eliminated and changed to multi-coil matching. Although the alignment problem has been solved to a certain ext...
