Description

Technical Field

[0001] This invention relates to the field of gallium nitride chargers, and more particularly to a gallium nitride USB charger with an automatic power-off function and its application method. Background Technology

[0002] Charging refers to the process by which an energy storage device receives electrical energy from an external circuit and converts it into the chemical energy of a battery. A charger is a general term for such devices. With the continuous advancement of technology, various types of chargers have emerged, among which gallium nitride (GaN) chargers are widely used due to their small size and high power.

[0003] Chinese patent CN113067382A discloses a safety charger with automatic power-off function, including a hollow charger shell. A liquid storage block is glued to the inner wall of the charger shell. The liquid storage block has a hollow structure. A semiconductor cooling chip is fixedly connected through the top wall of the liquid storage block. A heat-conducting plate is glued to the upper surface of the semiconductor cooling chip. A charging module is glued to the heat-conducting plate. Two contact plates are slidably connected through the liquid storage block and the charger shell. A sliding plate is sealed and slidably sleeved inside the liquid storage block. A conductive sheet is glued to the lower surface of the sliding plate.

[0004] The charging devices mentioned above only disconnect the charging circuit after the battery is fully charged. They do not have the function of automatically cutting off the power using digital control technology if a charging abnormality occurs during the charging process.

[0166] Working principle and usage of this invention:

[0167] Step 1, Pre-setting:

[0168] Power the gallium nitride USB charger described in this invention by pressing the power switch, and then perform debugging.

[0169] The second step is to use:

[0170] Fix it. Place the item to be charged on the movable cushion plate 303 with the charging port facing the second cuboid hollow container 102. Pair and connect the remaining Bluetooth modules.

[0171] After that, the first distance sensor module outputs the collected signal to the microprocessor; the microprocessor outputs a signal to the electric lifting device, and the electric lifting device drives the movable cushion plate 303 to move downwards, so that the item to be charged falls into the rectangular frame 105.

[0172] The second distance sensor module outputs the collected signal to the microprocessor; the microprocessor outputs a signal to the second lead screw motor 304. The second lead screw motor 304 adjusts the position of the item to be charged by controlling the position of the "L"-shaped limiting plate 305 to ensure that the charging port of the item to be charged faces the first "U"-shaped opening through groove 109.

[0173] The microprocessor outputs a signal to the first lead screw motor 201 and the third lead screw motor 404 with a time delay.

[0174] The first lead screw motor 201 drives the "convex"-shaped hollow container 104 to move in front of the third lead screw motor 404 through the lifting plate 202.

[0175] The third lead screw motor 404 starts with a time delay and pushes the USB charging device on the movable charging block 401 into the charging port of the item to be charged through the force application rod 405, and starts to charge the item to be charged.

[0176] After that, the third lead screw motor 404 drives the force application rod 405 to reset.

[0177] The charging personnel close the movable cover plate 501.

[0178] During charging, the voltage sensor module, the temperature sensor module and the current sensor module output signals to the microprocessor. The microprocessor combines the battery charging characteristic curve and outputs a signal to the first lead screw motor 201; the first lead screw motor 201 moves up orderly (according to the charging progress), and the charging status is displayed in real time through the display screen.

[0179] When charging is completed, the first lead screw motor 201 moves the movable charging block 401 up to the preset position, and the second circular positioning groove on the movable charging block 401 is inserted into the "L"-shaped force application rod 407. The fourth lead screw motor 406 pulls out the USB charging device of the movable charging block 401 through the "L"-shaped force application rod 407 to reduce power consumption and effectively extend the service life of the charger and the battery of the item to be charged.

[0180] At the same time, the microprocessor outputs signals to the color-changing light-emitting diode, the display screen and the voice module; the color-changing light-emitting diode shows green, the display screen shows that charging is completed, and the voice module emits a voice indicating that charging is completed through the speaker.

[0181] Step 3, Intelligent Transfer:

[0182] When a mobile phone is connected to the GaN USB charger of this invention via Bluetooth, during the charging process, when a call comes in, the Bluetooth module outputs a signal to the microprocessor, and the microprocessor outputs a signal to the display screen and the color-changing LED. The display screen displays the call information, and the color-changing LED displays red and flashes.

[0183] The pyroelectric infrared sensor module detects whether there are people charging within its range. If there are people charging, the voice module will broadcast the incoming call message through the speaker.

[0184] When the person charging presses the play switch, the Bluetooth module connects to the phone, allowing them to talk directly to the other party through the speaker and microphone.

[0185] If no one is available to charge the device, the voice module prompts the other party to leave a message via the speaker, while the recording chip module and microphone record the information.

[0186] After the charging personnel returned, they pressed the play switch, and the recording chip module played the message through the speaker and microphone.

[0187] When the voltage sensor module, temperature sensor module, or current sensor module detects an abnormal condition (severe deviation from the battery charging characteristic curve, rapid temperature changes, etc.), it outputs a signal to the microprocessor. The microprocessor then outputs signals to the lead screw motor 201, lead screw motor 406, the display screen, and the color-changing LED, initiating an emergency power-off procedure. Specifically, lead screw motor 201 moves the movable charging block 401 upwards to a preset position, causing the "L"-shaped force-applying rod 407 to insert into the circular positioning groove 2 on the movable charging block 401. Lead screw motor 406 then uses the "L"-shaped force-applying rod 407 to pull out the USB charging device 403 from the movable charging block 401. Simultaneously, the display screen shows a problem information, and the color-changing LED displays red and flashes.

[0188] The voice module emits a warning voice through the speaker.

[0189] If the phone remains unattended for an extended period and its battery level is below 20%, the microprocessor receives a signal from the Bluetooth module and repeats step two to ensure the phone has sufficient battery power.

Pair and connect the remaining Bluetooth modules; Then, the distance sensor module 1 outputs the collected signal to the microprocessor; the microprocessor outputs a signal to the electric lifting device, which drives the movable pad to move down, so that the item to be charged falls into the rectangular frame. Distance sensor module 2 outputs the collected signal to the microprocessor; the microprocessor outputs a signal to lead screw motor 2; lead screw motor 2 adjusts the position of the item to be charged by controlling the position of the "L"-shaped limit plate, ensuring that the charging port of the item to be charged is aligned with the "U"-shaped opening through slot 1; the microprocessor outputs a delayed signal to lead screw motor 1 and lead screw motor 3; lead screw motor 1 moves the "convex"-shaped hollow container to the front of lead screw motor 3 via the lifting plate; The lead screw motor starts after a delay and pushes the USB charging device on the movable charging block into the charging port of the item to be charged through the force rod, thus starting the charging of the item; afterwards, the lead screw motor drives the force rod to reset; the charging personnel then close the movable cover. During charging, the voltage sensor module, temperature sensor module, and current sensor module output signals to the microprocessor. The microprocessor, based on the battery charging characteristic curve, outputs signals to the lead screw motor. The lead screw motor moves upward in an orderly manner according to the charging progress, and the charging status is displayed in real time on the display screen. Once charging is complete, the first lead screw motor moves the movable charging block to a preset position, and the second circular positioning groove on the movable charging block is inserted into the "L"-shaped force rod; the fourth lead screw motor pulls out the USB charging device of the movable charging block through the "L"-shaped force rod to reduce power consumption and effectively extend the lifespan of the charger and the battery of the item to be charged. Simultaneously, the microprocessor outputs signals to the color-changing LED, display screen, and voice module; the color-changing LED displays green, the display screen indicates charging is complete, and the voice module emits a charging completion voice message through the speaker; the third step is intelligent call transfer: the phone is connected to the gallium nitride USB charger via Bluetooth. During charging, when a call comes in, the Bluetooth module outputs a signal to the microprocessor, which in turn outputs signals to the display screen and the color-changing LED. The display screen shows the caller information, and the color-changing LED displays red and flashes; the pyroelectric infrared sensor module detects whether there is a person charging within range. If there is, the voice module emits the caller's voice message through the speaker; when the person charging presses the play switch, the Bluetooth module connects the call, allowing them to speak directly with the other party through the speaker and microphone; If no one is available to charge the device, the voice module prompts the other party to leave a message via the speaker, and the recording chip module and microphone record the information. When the charging personnel return, they press the play switch, and the recording chip module plays the message through the speaker and microphone. When the voltage sensor module, temperature sensor module, or current sensor module detects an abnormality, it outputs a signal to the microprocessor. The microprocessor then outputs signals to lead screw motor 1, lead screw motor 4, the display screen, and the color-changing LED, initiating an emergency power-off procedure. Specifically, lead screw motor 1 moves the movable charging block to a preset position, inserting the "L"-shaped force rod into the circular positioning groove 2 on the movable charging block; lead screw motor 4 uses the "L"-shaped force rod to eject the USB charging device from the movable charging block; simultaneously, the display screen shows a problem message, the color-changing LED displays red and flashes; and the voice module emits a warning voice through the speaker.
