Unless otherwise specified, "plurality" means two or more.

[0021] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0022] like Figures 1 to 4As shown, a magnetic absorption and shrinking plug fast charging power bank includes a power bank body, the power bank body includes a shell 1, and a data line 2 and a power supply component 3 arranged in the shell 1. A pull-out port 4 is arranged on the side of the shell 1, and a magnetic attraction mechanism 5 is arranged at the pull-out port 4. The data line 2 is connected to the power supply component 3 and the magnetic attraction mechanism 5 respectively. The magnetic attraction mechanism 5 includes a fixing seat 51 and a pull-out component 52. The magnetic force is used to realize the automatic adsorption and fixation of the pull-out component 52. Specifically, a first strong magnet 53 is arranged on the fixing seat 51, and a second strong magnet 53 is arranged on the pull-out component 52. Strong magnet 54, the first strong magnet 53 and the second strong magnet 54 are positioned opposite to each other and attract each other, the pulling component 52 includes a connecting seat 521 and a pulling block 522, the connecting seat 521 is installed at the rear end of the fixed seat 51, one end of the data cable 2 passes through the connecting seat 521 and is connected to the power supply component 3, and the other end is connected to the pulling block 522. The pulling block 522 is also provided with a charging plug 6 on the side facing the pulling port 4, and the data cable 2 passes through the inside of the pulling block 522 and extends to the periphery of the charging plug 6 to ensure smooth movement of the data cable 2 during the pulling process. During operation, due to the effect of magnetic force, the user only needs to gently pull out the pull-out block 522 from the pull-out opening 4 to pull out the data cable 2 and expose the charging plug 6 for use. When it is not needed, the charging plug 6 only needs to be pushed back into the pull-out opening 4, and the first strong magnet 53 and the second strong magnet 54 will attract each other to achieve automatic storage. After storage is completed, the pull-out block 522 will not fall off the pull-out opening 4 easily, thereby achieving a stable connection with the shell 1, which not only makes it convenient to store the data cable 2, but also extends the service life of the charging head.

[0023] The power supply component 3 includes a battery 31 and a circuit board 32. The circuit board 32 is connected to the data line 2 and the battery 31 respectively. The circuit board 32 can control the charging and discharging of the battery 31, and can also process the electrical energy transmitted from the data line 2, so that the power bank can safely and effectively store and release electrical energy, and provide a stable power supply for various electronic devices.

[0024] A Type-C plug 7 and a Lightning plug 8 are also provided on the side of the shell 1. The Type-C plug 7 and the Lightning plug 8 are respectively connected to the circuit board 32. These plugs are connected to the circuit board 32 of the power bank, and can transmit electrical energy to the battery 31 to charge the power bank, thereby realizing the function of the power bank to charge the objects to be charged. Different types of plugs can meet the needs of different devices and provide a faster and more stable charging experience for the power bank.

[0025] The front of the housing 1 is provided with an LED power indicator 9, which is usually realized by a circuit board 32 and a power detection chip. When the power bank is connected to the power supply, the power detection chip detects the power of the battery 31 and converts it into a digital signal, and then transmits the digital signal to the LED power indicator through the circuit board 32. The LED power indicator is usually divided into four grids, each corresponding to 25% of the power of the power bank. Therefore, when one grid of the LED power indicator is lit, it means that the power of the power bank is 25%; when two grids of the LED power indicator are lit, it means that the power is 50%; when three grids of the LED power indicator are lit, it means that the power is 75%; when all the LED power indicator lights are lit, it means that the power is full. This design allows users to easily understand the power of the power bank, so as to better use and master the charging status of the power bank.

[0026] The principle of the implementation mode of the present application is: when in use, manually pull out the pull-out block 522 from the pull-out port 4, and the charging head and data cable 2 on the pull-out block 522 are exposed, and the charging head is connected to the object to be charged. The user can adjust the length of the stretched data cable 2 according to their own needs, press the control switch, and start the power bank. When use is completed, just separate the charging head from the object to be charged, and the first strong magnet 53 and the second strong magnet 54 will attract each other to absorb the pull-out assembly 52 back to the fixed seat 51 to achieve automatic storage, thereby protecting the data cable 2 and the charging port. At the same time, the circuit board 32 will control the battery 31 to stop discharging, ensuring the safety of the power bank and the effective storage of electrical energy. The LED power indicator light 9 correspondingly displays the remaining power of the power bank.

[0027] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
