Description
Technical Field
[0001] The present invention relates to an LCD mobile power bank which is different from many LCD mobile power banks on the market. The fundamental difference lies in that the present invention adopts a 46950 lithium battery as a battery core, and the indicating part adopts a micro-stepping motor to drive the digital pointer. The output power is as high as 30,000 mAh, which can realize normal or fast charging of mobile phones. Background Art
[0002] At present, due to the popularity of artificial intelligence and 5G technology, communication information is frequent. Every day, mobile phone users charge their phones at least 1.2 billion times, and emergency charging is used at least 60 million times. It can be seen that charging mobile phones has become a rigid need in people's daily lives. Unfortunately, the mobile phone power banks on the market are almost all the same, all with LED or LCD indicators, so there is an urgent need for a novel charging device to break the embarrassment of existing power bank products. In addition, almost all mobile phone power banks on the market use soft-pack batteries or multiple 18650 batteries as battery materials. Due to their low output power, the number of times this type of power bank can charge mobile phones is also frequently limited.
[0003] Based on this, the present invention proposes a mobile phone power bank that uses an aluminum profile shell and a 46950 battery as the main body of the mobile power bank. The topological structure design is characterized in that only one 46950 battery is used to solve the heating problem that may be generated when the low voltage and high current mode is used to "speed up" the charging of the mobile phone; the basic size of the 46950 is a large cylindrical condensed lithium ion battery with a diameter of 46 mm and a height of 95 mm, which is packaged in aluminum and plastic. The electrolyte and electrode parts adopt a high nickel plus graphite system solution, with an internal resistance of 2 milliohms, a capacity of up to 30,000 mAh, a charging limit working voltage of 4.25V, a discharge cut-off voltage of 2.5V, and a normal life of up to 2,000 cycles. The numerical control indication part adopts an LED indicator light plus a digital pointer display solution driven by a micro-stepping motor, which truly realizes charging for 6 minutes and talking for 2 hours, and completes the gorgeous transformation of the mobile phone power bank in a simple and complex way. Summary of the invention
[0004] The 46950 lithium battery digital pointer power bank includes: a front digital panel frame, a housing, a 46950 lithium battery, a digital pointer drive movement, a PCB circuit A board and a PCB circuit B board. The main points are: The front digital panel frame is composed of a digital pointer, a digital panel and a panel frame edge, wherein the digital panel is engraved with a digital scale of voltage, and the digital panel also has a charging indicator light and a discharging indicator light. When charging, the charging indicator light is on, and when discharging, the discharging indicator light is on; When charging or discharging, the digital pointer deflects synchronously at the designated digital position on the digital panel; The shell is a hexahedron with a hollow circular cavity inside, and the 46950 lithium battery is installed therein, with the positive electrode of the 46950 lithium battery facing the front digital panel frame and the negative electrode of the 46950 lithium battery pointing to the bottom plate of the shell; The bottom plate of the housing has a start / fast charge / pause button, which is a three-function button. The bottom plate of the housing also has a TYPE-C input socket, two USB output sockets and a row of charging quota indicator lights; During charging operation, the charging amount indicator light is consistent with the voltage scale indicated by the digital pointer on the front digital panel frame; The digital pointer driving movement is encapsulated in a space surrounded by a hexagonal upper cover and a hexagonal bottom shell; The digital pointer driving movement is welded on the PCB circuit A board and driven by the VMOS-A chip; the PCB circuit B board is encapsulated in the space of the digital pointer driving movement, and one side of the PCB circuit B board is surface-mounted with a single-chip microcomputer chip, a logic chip, an optical coupling chip, a power conversion chip, and an AD conversion chip, and the other side is installed with an iron core body, a driving coil, a driving gear, and an output shaft driven gear. Then, the rotating shaft is connected to the digital pointer after the rotating shaft extends out of the step; The relationship between PCB circuit board A and PCB circuit board B is as follows: PCB circuit board B is responsible for the logic control of the 46950 type lithium battery digital pointer power bank, and the PCB circuit board A is responsible for the power control of the 46950 type lithium battery digital pointer power bank; In addition, the VMOS-B chip on PCB circuit A is also responsible for the power management of the 46950 lithium battery digital pointer power bank. The single-chip microcomputer chip and AD conversion chip on PCB circuit B cooperate with the VMOS-B chip on PCB circuit A to support the 4C fast charging curve, which can be charged from 10% to 70% in 9 minutes. During installation, the external thread A on the front digital panel frame is screwed into the internal thread B of the front digital panel frame, and then the external thread C on the front digital panel frame is screwed into the internal thread of the power bank shell, so that the digital panel frame and the shell form a whole.
[0005] Furthermore, the front digital panel frame and the housing are both injection-molded from high-temperature resistant engineering plastics; and the digital pointer is injection-molded from lubricated nylon 66 material.
[0006] Furthermore, the iron core body of the digital pointer drive movement welded on the PCB circuit A is changed from the previous Permalloy to an iron-based amorphous alloy laminate. Because the iron-based amorphous alloy has low iron loss and high saturation magnetic induction intensity, the driving voltage of the digital pointer drive movement can be reduced from the previous 5V to 2.5V.
[0007] Furthermore, the chips on the PCB circuit A board and the PCB circuit B board are powered by an ultra-low voltage of 2.7V.

When charging, the charging indicator light (1-4) is lit, and when discharging, the discharging indicator light (1-5) is lit; When charging or discharging, the digital pointer (1-1) deflects synchronously at a designated digital position on the digital panel (1-2); The shell (2) is a hexahedron in appearance and a hollow circular cavity in the interior, wherein the 46950 type lithium battery is installed therein, the positive electrode (3-1) of the 46950 type lithium battery points to the front digital panel frame (1), and the negative electrode (3-2) of the 46950 type lithium battery points to the shell bottom plate (2-1); The housing bottom plate (2-1) is provided with a start / quick charge / pause button (2-2) which is a three-function button, a TYPE-C input socket (2-3), two USB output sockets (2-4) and a row of charging quota indicator lights (2-5); During charging operation, the voltage scale indicated by the charging amount indicator light (2-5) and the digital pointer (1-1) on the front digital panel frame (1) on the digital panel (1-2) is consistent; The digital pointer driving movement (4) is encapsulated in a space surrounded by a hexagonal upper cover (4-1) and a hexagonal bottom shell (4-2); The digital pointer driving movement (4) is welded on the PCB circuit board A (5) and driven by the VMOS-A chip (5-1); the PCB circuit board B (6) is packaged in the space of the digital pointer driving movement (4); one side of the PCB circuit board B (6) is surface-mounted with a single-chip microcomputer chip (6-1), a logic chip (6-2), an optical coupling chip (6-3), a power conversion chip (6-4), and an AD conversion chip (6-5); the other side is mounted with an iron core body (6-6), a driving coil (6-7), a driving gear (6-8), and an output shaft driven gear (6-9); then, the rotating shaft is connected to the digital pointer (1-1) through the rotating shaft extending step (4-3); The relationship between the PCB circuit board A (5) and the PCB circuit board B (6) is as follows: the PCB circuit board B (6) is responsible for the logic control of the 46950 type lithium battery digital pointer power bank, and the PCB circuit board A (5) is responsible for the power control of the 46950 type lithium battery digital pointer power bank; In addition, the VMOS-B chip (5-2) on the PCB circuit board A (5) is also responsible for the power management of the 46950 type lithium battery digital pointer power bank, wherein the single chip microcomputer chip (6-1) on the PCB circuit board B (6) cooperates with the VMOS-B chip (5-2) on the PCB circuit board A (5) to support the 4C fast charging curve, that is, it can be charged from 10% to 70% within 9 minutes; During installation, the external thread A (1-7) on the front digital panel frame (1) is screwed into the internal thread B (1-8) of the front digital panel frame (1), and then the external thread C (1-9) on the front digital panel frame (1) is screwed into the internal thread (2-6) of the power bank shell, so that the digital panel frame (1) and the shell (2) form a whole.
[0013] Furthermore, the front digital panel frame (1) and the housing (2) are both made of high temperature resistant engineering plastics by injection molding; and the digital pointer (1-1) is made of nylon 66 by injection molding.
[0014] Furthermore, the iron core (6-6) in the digital pointer driving movement (4) welded on the PCB circuit board A (5) is replaced by an iron-based amorphous alloy laminate instead of the previous Bohm alloy. Because the iron-based amorphous alloy has low iron loss and high saturation magnetic induction intensity, the iron loss is very small, so that the driving voltage of the digital pointer driving movement (4) is also reduced from the previous 5V to 2.5V.

Beneficial Effects
[0017] The 46950 lithium battery digital pointer power bank proposed by the present invention has the following significant beneficial effects: The present invention proposes a digital pointer power bank solution based on a 46950 lithium battery, introduces a digital pointer driven by a single 46950 lithium battery and a digital pointer driving movement, supports one-touch 4C fast charging, and thus changes the embarrassing situation that existing power bank products on the market are all the same.
[0018] Another most substantial improvement of the present invention is to modularize the digital pointer drive movement, and to change the iron core body in the digital pointer drive movement from the previous Permalloy to an iron-based amorphous alloy laminate. Since there are no grain boundaries in the iron-based amorphous alloy that are prone to local corrosion, it has higher and more uniform corrosion resistance than silicon steel sheets or Permalloy, and is an excellent soft magnetic material for reducing iron loss. This improvement also greatly reduces the driving voltage of the micro stepping motor.
[0019] The addition of a single high-power 46950 lithium battery also makes fast charging of mobile phones possible, because the standard charge and discharge current of the 46950 lithium battery is 10A, and 4C charging is no problem.
[0020] Secondly, the present invention adopts an integrated topological structure and a modular installation mode of the digital pointer drive movement, which simplifies the installation process, thereby ensuring the most economical system and the best overall performance.
[0021] In this specification, specific implementation examples are used to illustrate the principles and operation modes of the present invention, which are only used to help understand the core idea of the present invention and should not be understood as limiting the present invention.
