A portable solar power bank with light tracing and a charging method

Abstract

The invention discloses a portable solar power bank with light tracing, including a battery backplane, a solar panel is arranged on the battery bottom plate, a solar panel includes a support rotary panel, a support rotary plate is connected with a battery panel assembly through an articulated shaft, a corn device is arranged in the middle of the contact surface of the support rotating plate and the battery bottom plate, the corner device includes a micro drive motor mounted in a battery chassis, the motor shaft of the micro drive motor is connected with a speed reducer, the speed reducer comprises a double-sided rack ring fixedly mounted on the bottom of the supporting rotary plate, the center of the double-sided rack ring is provided with a sun gear connected with the output shaft of themicro drive motor, Between that sun gear and the double-sided rack re, a clutch wheel device is arranged between the double-sided rack ring and the articulated shaft, and a light tracing device is arranged on the top of the battery panel assembly, so that the structure of the solar energy power bank is simple and portable, the stable power output can be provided, and the charging efficiency of thesolar energy power bank can be improved.

Description

technical field [0001] The invention relates to the field of charging treasures, in particular to a portable solar charging treasure with ray tracing and a charging method. Background technique [0002] Charging treasure, also known as "mobile power supply", "external battery", "backup battery", "digital charging companion", "external battery" and "mobile power supply", this concept is developed with the popularity and rapid growth of digital products It is defined as: a portable power supply that is convenient and easy to carry. In view of the increasingly diversified functions of digital products, more frequent use, and more and more close correlation with our daily life, how to improve the use time of digital products and facilitate people's lives , Replenish the power supply in time and give full play to its maximum function. The importance of power bank is even more urgent. Mobile power supply is the best solution to solve this problem. Carrying a mobile power supply wi...

Problems solved by technology

[0005] (1) The structure of the power bank is relatively fixed, emphasizing the integrity of the power bank, and the installation of the solar panel on the power bank makes the charging time of the power bank Longer, the power conversion function is weak, and the charging of the lithium battery needs to be completed under the sunlight, and the solar panel with a fixed structure cannot complete the tracking of the light intensity;

[0006](2) At the same time, during the charging process, the output voltage of the solar panel is in a state of dynamic change for a long time, which is not convenient for charging the lithium battery, and it is easy to reduce the lithium battery service life, and the lithium battery needs to be charged to a certain amount of electricity in order to achieve the power output of the load
