The position between the two sides of the upper part of the storage box (102) and the two sides of the locking point of the limiting track (104).

[0023] The limit track 104 is made of carbon fiber, which ensures strength while reducing weight, and the surface is treated with anti-slip material.

[0024] Reference Figures 1-2 The inner wall of the flip cover 101 is provided with a storage groove 106.

[0025] Storage slot 106 is used to store items such as card holders.

[0026] Reference Figures 1-2 The power bank 103 has two data cables and two USB ports 118 embedded in its outer shell. The storage box 102 has a channel 113 on its side wall for the data connection cables to pass through. A sealing cover 107 for sealing the channel 113 is slidably provided on the side wall of the storage box 102.

[0027] The storage box 101 also houses a charging module, which includes a rechargeable battery, a charging management circuit, and a discharging circuit. One end of the charging management circuit connects to the external interface 114, and the other end connects to the rechargeable battery, responsible for stably charging the battery from an external power source. The discharging circuit of the lighting lamp 116, according to instructions from the main control circuit board 109, outputs battery power to the device's charging interface to charge mobile phones and other devices, while also providing overcharge, over-discharge, and overcurrent protection. It facilitates connecting the data cable through the channel port 113 to the device being charged. The charging module uses a 15000mAh lithium iron phosphate battery, which is highly safe and has a long cycle life. The charging management circuit uses an MCP73871 chip, supporting fast charging input up to 5V / 3A. The discharging circuit uses a Silergy SY8209 chip, capable of stably outputting 5V / 3A current to power external devices, while also providing comprehensive overcharge, over-discharge, overcurrent, and short-circuit protection. The sealing cover 107 is 1.2mm thick.

[0032] The mirror 115 is connected to the main body of the device via a hinge. The hinge has a built-in angle sensor that transmits the rotation angle information of the mirror 115 to the main control circuit board 109. When the user rotates the mirror 115, the main control circuit board 109 can control the brightness of the lighting lamp 116 according to the angle change to adapt to the light requirements of different usage angles. The lighting lamp 116 is connected to the main control circuit board 109 via a constant current drive circuit. The main control circuit board 109 adjusts the output current of the constant current drive circuit according to the ambient light sensor data and user operation commands, thereby controlling the brightness of the lighting lamp 116. The lighting assembly 200 can also be equipped with a heat dissipation structure to ensure stability during long-term use. The main control circuit board 109 uses a Renesas Electronics RA6M4 microcontroller, which has rich peripheral interfaces and can flexibly connect various functional modules. It has 512KB of Flash storage and 128KB of SRAM on-chip, sufficient to run complex device control logic and store necessary operating data. The mirror 115 is made of 10cm square anti-fog glass, and a Bosch BMI160 is attached to the back of the mirror 115. The inertial measurement unit can accurately sense the rotation and tilt angle of mirror 115. The rotating shaft is made of high-strength aluminum alloy and is connected to the main body of the equipment through a self-lubricating bearing to ensure smooth rotation even under frequent use. The lighting lamp 116 uses Osram P8 series LED chips, with each chip providing 800 lumens of brightness. The constant current drive circuit is based on TI's LM3402 chip and can accurately adjust the output current according to the PWM signal of the main control circuit board 109 to achieve a wide range of brightness adjustment from 1% to 100%. The heat dissipation part uses copper heat sink fins, which are tightly bonded to the LED chip substrate with thermal paste to enhance heat dissipation efficiency.

[0034] The device has a built-in Bluetooth chip that pairs with the user's mobile phone via Bluetooth. It uses AES encryption algorithm to ensure data transmission security and transmits signal strength data between the device and the mobile phone to the main control circuit board 109 in real time. When the signal strength is lower than the preset threshold, the main control circuit board 109 determines that the device is out of safe distance and immediately triggers the anti-loss alarm program on the mobile phone. In addition to the conventional sound alarm, the alarm can also be set to mobile phone vibration and pop-up reminder. Users can also customize the alarm ringtone.

[0035] Working principle: After the slider 110 slides out, the exposed position of the flip cover 102 is equipped with a fingerprint lock 111 or a password lock 112. Both the flip cover 102 and the storage box 101 are equipped with opening and closing electromagnets 105. Through the fingerprint lock 111 and the password lock 112, the opening and closing magnets of the flip cover 102 and the storage box 101 can be opened, allowing the flip cover 102 to be rotated to open the mobile phone charging device. The side of the flip cover 102 facing the storage box 101 after opening is provided with a card slot for inserting an ID card. The inside of one side of the storage box 101 contains an area for a small power bank 103 and an area for electronic components. The channel opening 113 is opened by sliding the sliding sealing cover 107 up and down, allowing the flip cover 102 to be closed, and the mobile phone can still be charged with a data cable. The power bank 103 is magnetically attached to the storage box 101 and can be detached for charging. An external interface 114 is provided in the direction perpendicular to the plane of the data cable, which can also be used for external charging. The flip cover 102 A square mirror 115 is provided on the inside. The mirror 115 can rotate through a rotating shaft and can adjust its angle. There is a light 116 located outside the rotating shaft and between the magnetic buckle to facilitate the use of the mirror 115. The sealing cover 107 and the dustproof sheet 108 are used to protect the internal components and extend their service life.
