This fails to meet the personalized and engaging needs of consumers in the AI ​​era. Furthermore, the wireless charging coils in wireless chargers typically have a circular structure.

[0017] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.

[0018] This invention discloses a wireless charging device for LED displays, combined with Figures 1 to 3 As shown, it includes a charger body 1, within which a circular charging coil 2 and a main board 6 are provided. A non-coil cavity region 3 is formed at the center of the circular charging coil 2, and an LED eye module 4 is located inside the non-coil cavity region 3. The LED eye module 4 and the circular charging coil 2 are electrically connected to the main board 6. The main board 6 integrates a main MCU module and an AI blinking algorithm module, wherein: The AI ​​blinking algorithm module has preset blinking parameters including average blinking frequency, single blinking duration and eye closing interval. The AI ​​blinking algorithm module is based on the linear congruent random number algorithm to randomize the blinking parameters, adjust the fluctuation duration of each blinking interval and blinking duration, and set parameter constraint logic to generate a blinking control signal that represents the effect of natural blinking. The main MCU module is used to control the charging state of the circular charging coil 2 and to output control commands to the LED eye module 4 according to the blink control signal, thereby controlling the on / off timing of the LED lights in the LED eye module 4 to simulate the natural blinking effect of the human eye.

[0019] In the aforementioned wireless charger, the central region of the circular charging coil has a non-coil cavity area with a diameter of 18mm. An LED eye module is fixedly installed within this non-coil cavity area. The main board integrates a main MCU module and an AI blinking algorithm module. The AI ​​blinking algorithm module pre-stores blinking parameters obtained from research on human blinking frequency, and its software code is independently developed. Its core operational logic includes a random number generation unit and a state recognition unit, used to dynamically and randomly adjust the pre-stored blinking parameters and match the wireless charging working state. The main MCU module is electrically connected to the circular charging coil, the LED eye module, and the AI ​​blinking algorithm module. The AI ​​blinking algorithm module processes the pre-stored human blinking parameters to generate a natural blinking control signal. The main MCU module receives the control signal and controls the LED lights of the LED eye module to turn on and off, simulating the effect of a natural human blink. Compared with existing technologies, this invention not only fully utilizes the unused non-coil cavity area and achieves a natural human blinking effect, but also has a simple structure, low cost, and better meets application requirements.

[0020] Furthermore, the LED eye module 4 includes six LEDs 7, which are symmetrically distributed in two rows, left and right, with a spacing of 14mm between the two symmetrical LEDs 7. A light guide cover 5 is provided on the outer side of the LED eye module 4.

[0021] In this embodiment, the LED eye module includes six LEDs, which are either RGB LEDs or monochrome LEDs, fixedly positioned at the center of the non-coil void area or symmetrically distributed on both sides of the center, simulating the structure of a single or double eyelid. The LED eye module also includes a light guide cover, which is fixedly covered on the outside of the LEDs, and the shape of the light guide cover is adapted to the non-coil void area to make the light from the LEDs diffuse evenly and improve the blinking visual effect.

[0022] Furthermore, the AI ​​blinking algorithm module pre-stores the following human eye blinking parameters: blinking frequency of 10-20 times per minute, single blink duration of 0.1-0.4 seconds, and eye-closing interval of 2-6 seconds between two blinks. The eye-closing interval is randomly adjusted by the AI ​​algorithm to avoid mechanical blinking and achieve natural blinking. The core operation logic of the AI ​​blinking algorithm module is self-written, specifically including: dynamically and randomly adjusting the pre-stored eye-closing interval and blink duration parameters through a built-in random number generation unit to generate a non-fixed-period blinking sequence. Simultaneously, parameter threshold constraints are introduced to ensure that the randomly adjusted parameters are always within the reasonable range of natural human blinking. The algorithm also includes a status recognition unit, used to receive the wireless charging working status signal (standby / charging) transmitted from the main MCU module, and match the preset blinking state according to the corresponding state to achieve linkage between the blinking effect and the device's working status. Its core logic does not rely on external programs or existing algorithm frameworks and can be directly integrated into the main MCU module for operation.

[0023] In a preferred embodiment of the present invention, the AI ​​blinking algorithm module has a built-in state linkage submodule, which is used to receive wireless charging working status data transmitted by the main MCU module, and dynamically match the corresponding blinking logic data.

[0024] As a preferred approach, the AI ​​blinking algorithm module and the main MCU module transmit signals via a serial communication protocol or a UART communication protocol.

[0025] In the aforementioned wireless charger, the main MCU module is an APT32F1023 or a microcontroller of equivalent performance. This main MCU module also controls the charging start / stop and charging power adjustment of the circular charging coil. Furthermore, the main MCU module and the AI ​​blinking algorithm module are integrated on the same motherboard, simplifying the product structure and reducing costs. Further, the AI ​​blinking algorithm module and the main MCU module communicate via I2C or UART protocols to ensure the stability and timeliness of control signal transmission, avoiding stuttering or delays in the blinking effect.

[0026] Based on this, the present invention also discloses a control method for an LED display wireless charging device, please refer to [link / reference]. Figures 1 to 4 The control method is implemented based on the wireless charger described above, and the control method includes: The blinking parameters, including the average blinking frequency, the duration of a single blink, and the eye-closing interval, are written into the AI ​​blinking algorithm module. The AI ​​blinking algorithm module is based on the linear congruent random number algorithm to randomize the blinking parameters, adjust the fluctuation duration of each blink interval and the blinking duration, and set parameter constraint logic to generate a blinking control signal that represents the effect of natural blinking. The main MCU module controls the charging state of the circular charging coil 2 and outputs control commands to the LED eye module 4 according to the blink control signal, thereby controlling the on / off sequence of the LED lights in the LED eye module 4 to simulate the natural blinking effect of the human eye.

[0027] In the above control method, the average blinking frequency in the blinking parameters is 10-20 times per minute, the duration of a single blink is 0.1-0.4 seconds, and the interval between blinks is 2-6 seconds. Specifically, it includes the following steps: Step S1: Investigate the parameters of human eye blinking frequency, blinking duration and eye closing interval. By investigating the natural blinking state of people of different age groups, including the differences in blinking frequency between teenagers and adults, the parameters are pre-stored into the AI ​​blinking algorithm module. Step S2: The AI ​​blinking algorithm module autonomously processes the pre-stored human eye blinking parameters to generate randomized and natural blinking control signals (the control signals include the LED light's on / off timing and duration). The processing logic is implemented by self-written software code. The specific processing steps are as follows: First, the pre-stored human eye blinking parameter thresholds are called, and a random eye-closing interval of 2-6 seconds and a random blinking duration of 0.1-0.4 seconds are generated using a random number generation algorithm (such as a linear congruent random number algorithm). Second, the wireless pre-working state (standby / charging) is determined through state recognition logic. If it is in charging state, the working logic of the eye LED module is adjusted based on the charging state transmitted by the main MCU module. Finally, the randomized on / off timing and duration parameters are converted into digital control signals and transmitted to the main MCU module to avoid mechanical blinking and improve the naturalness of blinking. Step S3: The main MCU module receives the blink control signal sent by the AI ​​blink algorithm module and synchronously outputs control commands to the LED eye module. In step S4, the LED eye module controls its own LED lights to turn on and off according to a preset timing sequence based on the control instructions of the main MCU module, simulating the natural blinking effect of the human eye. Furthermore, in step S2, the computational processing logic of the AI ​​blinking algorithm module also includes: when the wireless charger is in standby mode, the blinking frequency is 10-20 times per minute; wherein, the probability of triggering a complete blink and an incomplete blink can be adjusted according to the set parameters; when the wireless charger is charging, the eye LED light is turned off, and when the wireless charger stops charging, the blinking function is restored; realizing the linkage between the blinking effect and the charging status, and improving the user interaction experience.

[0028] In a preferred embodiment of the present invention, the AI ​​blinking algorithm module has a built-in state linkage sub-module. The state linkage sub-module receives wireless charging working status data transmitted by the main MCU module and dynamically matches the corresponding blinking logic data. When the wireless charger is in standby mode, the blinking frequency is 10-20 times per minute. When the wireless charger is charging, the LED eye module 4 is turned off. When the wireless charger stops charging, the blinking function is restored.

[0029] Based on this, the state linkage submodule adjusts the probability of triggering complete blinking and incomplete blinking according to the set parameters.

[0030] As a preferred embodiment, the present invention also includes a parameter constraint step for limiting the randomly adjusted blink parameters from exceeding the blink parameter range.

[0031] The wireless charger and control method disclosed in this invention have the following advantages over existing technologies: First, this invention cleverly utilizes idle space to achieve low-cost innovation. By fully utilizing the 18mm diameter non-coil cavity in the center of the circular charging coil of the wireless charger, an LED eye module is set up. This eliminates the need for additional internal space or significant increases in hardware costs. The product's functionality is innovated simply by adding a few LEDs and self-written software code, solving the problem of wasted idle space in existing technologies. Second, this invention achieves natural blinking based on AI algorithms, enhancing fun and user experience. Specifically, through a self-developed AI blinking algorithm, based on survey data on human blinking frequency, it simulates the effect of natural human blinking and randomly adjusts... The blink interval is adjusted to adapt to different charging states, avoiding the mechanical flickering of traditional LED lights. The blinking effect is natural and realistic, greatly enhancing the product's fun and innovation, and meeting the personalized needs of consumers in the AI ​​era. At the same time, by combining hardware structure (LED eye module, MCU, coil) and software algorithm (self-developed AI blinking algorithm), both product structure and control method innovation are achieved. In addition, the LED eye module of this invention can use 6 LEDs to adapt to non-coil cavity areas of different sizes. The light guide cover enhances the visual effect. The main MCU module simultaneously realizes charging control and blink control, simplifying the product structure. It can be widely used in wireless chargers for mobile phones with various circular coils, with strong adaptability.
