Description

Technical Field

[0001] The present invention relates to a mobile power bank with LCD display that is different from many other mobile power banks on the market. The fundamental difference lies in that the present invention uses a 46950 lithium battery as a battery core, and the indicator part adopts a micro-stepping motor to drive the digital pointer. Its output power is as high as 30,000 mAh, which can realize normal or fast charging of mobile phones. Background Art

[0002] Currently, China has over 1.3 billion mobile phone users. The widespread adoption of artificial intelligence and 5G technology has led to a surge in the number of people communicating with each other. Every day, mobile phone users charge their phones at least 1.2 billion times, with at least 60 million requiring emergency charging. This shows that charging a phone has become a necessity in people's daily lives. Unfortunately, the mobile phone power banks on the market are almost universally identical, featuring either LED or LCD indicators. Therefore, a novel charging device is urgently needed to address this issue. Furthermore, nearly all mobile phone power banks on the market use soft-pack batteries or multiple 18650 batteries as their core material. Due to their low output power, the number of times these power banks can charge a phone is often limited.

[0003] Based on this, the present invention proposes a mobile phone power bank with an aluminum profile housing and 46950 batteries as the main cell. Its topological design features a single 46950 battery, eliminating the heating issue that can occur when using a low-voltage, high-current mode to "speed up" mobile phone charging. The 46950 battery is a large cylindrical condensed lithium-ion battery with a diameter of 46 mm and a height of 95 mm, housed in an aluminum-plastic package. The electrolyte and electrodes utilize a high-nickel-graphite system, resulting in an internal resistance of 2 milliohms and a capacity of up to 30,000 mAh. The charging voltage is limited to 4.25V, the discharge cutoff voltage is 2.5V, and the normal lifespan can reach 2,000 cycles. The digital control indicator utilizes an LED indicator and a digital pointer driven by a micro-stepping motor, truly achieving a 6-minute charge and 2-hour talk time, effectively transforming the mobile phone power bank into a simple yet powerful solution. 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 mechanism, PCB circuit board A and PCB circuit board B. The key points are:

[0005] 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;

[0006] When charging or discharging, the digital pointer deflects synchronously at the designated digital position on the digital panel;

[0007] The shell is a hexahedron with a hollow circular cavity inside. 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;

[0008] The bottom panel of the housing has a start / fast charge / pause button, which is a three-function button. The bottom panel of the housing also has a TYPE-C input socket, two USB output sockets and a row of charging quota indicator lights.

[0009] 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;

[0010] The digital pointer driving movement is enclosed in a space surrounded by a hexagonal upper cover and a hexagonal bottom shell;

[0011] The digital pointer drive mechanism is soldered to PCB circuit board A and driven by a VMOS-A chip. PCB circuit board B is encapsulated within the space of the digital pointer drive mechanism. One side of PCB circuit board B 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. The other side is mounted with an iron core, a drive coil, a driving gear, and an output shaft driven gear. The rotating shaft extends out of the step and is connected to the digital pointer.

[0012] 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;

[0013] In addition, the VMOS-B chip on PCB circuit board A is also responsible for power management of the 46950 lithium battery digital pointer power bank. Among them, the single-chip microcomputer chip and AD conversion chip on PCB circuit board B cooperate with the VMOS-B chip on PCB circuit board A to support the 4C fast charging curve, which can charge from 10% to 70% in 9 minutes.

[0014] 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.

[0015] Furthermore, the front digital panel frame and the housing are both injection-molded from high-temperature resistant engineering plastics; while the digital pointers are injection-molded from lubricated nylon 66 material.

[0016] Furthermore, the iron core of the digital pointer drive movement soldered on PCB circuit A is changed from the previous Bomalloy to an iron-based amorphous alloy laminate. Because its 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.

[0017] Furthermore, the chips on PCB circuit A and PCB circuit B are powered by an ultra-low voltage of 2.7V.

[0018] Furthermore, the 46950 type battery is a condensed lithium-ion circular battery, which is packaged in aluminum plastic. It has a diameter of 46 mm and a height of 95 mm. The charging voltage is 4.25 volts, the discharge cut-off voltage is 2.5 V, the capacity is up to 30,000 mAh, the standard charge and discharge current is 10 A, and the cycle life is not less than 2,000 times.

[0066] The specific embodiments of the present invention are described below with reference to the accompanying drawings:

[0067] The 46950 lithium battery digital pointer power bank comprises: a front digital panel frame (1), a housing (2), a 46950 lithium battery (3), a digital pointer drive mechanism (4), a PCB circuit A board (5) and a PCB circuit B board (6). The main features are:

[0068] The front digital panel frame (1) is composed of a digital pointer (1-1), a digital panel (1-2) and a panel frame edge (1-6), wherein the digital panel (1-2) is engraved with a voltage digital scale (1-3), and the digital panel (1-2) is also provided with a charging indicator light (1-4) and a discharging indicator light (1-5). When charging, the charging indicator light (1-4) is lit, and when discharging, the discharging indicator light (1-5) is lit.

[0069] When charging or discharging, the digital pointer (1-1) deflects synchronously at a designated digital position on the digital panel (1-2);

[0070] The shell (2) is a hexahedron with a hollow circular cavity inside, and the 46950 lithium battery is installed therein, with the positive electrode (3-1) of the 46950 lithium battery pointing to the front digital panel frame (1), and the negative electrode (3-2) of the 46950 lithium battery pointing to the shell bottom plate (2-1);

[0071] 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 level indicator lights (2-5);

[0072] 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;

[0073] The digital pointer driving movement (4) is enclosed in a space surrounded by a hexagonal upper cover (4-1) and a hexagonal bottom shell (4-2);

[0074] 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 encapsulated 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 (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);

[0075] 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 type power bank, and the PCB circuit board A (5) is responsible for the power control of the 46950 type lithium battery digital pointer type power bank;

[0076] 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. Among them, 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;

[0077] 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.

[0078] Furthermore, the front digital panel frame (1) and the housing (2) are both injection-molded from high-temperature resistant engineering plastics; and the digital pointer (1-1) is injection-molded from nylon 66.

[0079] Furthermore, the iron core (6-6) in the digital pointer driving movement (4) soldered on the PCB circuit board A (5) is changed from the previous BoMo alloy to an iron-based amorphous alloy laminate. 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.

[0080] Furthermore, the chips on the PCB circuit A board (5) and the PCB circuit B board (6) are powered by an ultra-low voltage of 2.7V, thereby meeting the requirements of energy saving and consumption reduction.

[0081] Furthermore, the 46950 type battery is a condensed lithium-ion circular battery, which is packaged in aluminum plastic. It has a diameter of 46 mm and a height of 95 mm. The charging voltage is 4.25 volts, the discharge cut-off voltage is 2.5 V, the capacity is up to 30,000 mAh, the standard charge and discharge current is 10 A, and the cycle life is not less than 2,000 times. Beneficial effects

[0082] The 46950 lithium battery digital pointer power bank proposed in the present invention has the following significant beneficial effects:

[0083] The present invention proposes a digital pointer power bank solution based on a 46950 lithium battery, which introduces a single 46950 lithium battery and a digital pointer driven by a digital pointer drive movement, supports one-touch 4C fast charging, and thus changes the embarrassing situation of the existing power bank products on the market being all the same.

[0084] Another substantial improvement of the present invention is the modularization of the digital pointer drive movement and the replacement of the traditional Permalloy with an iron-based amorphous alloy laminate for the iron core. Because the iron-based amorphous alloy does not have grain boundaries susceptible to localized corrosion, it has higher and more uniform corrosion resistance than silicon steel sheets or Permalloy, making it an excellent soft magnetic material for reducing iron loss. This improvement also significantly reduces the drive voltage of the micro stepper motor.

[0085] 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.

[0086] 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.

[0087] In this specification, the principles and operating methods of the present invention are described using specific examples. These examples are intended only to facilitate understanding of the core concepts of the present invention and should not be construed as limiting the present invention. Those skilled in the art will appreciate that any changes in form and detail made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims are intended to fall within the scope of protection of the present invention.
