Technical Field

[0001] This utility model relates to the field of solar charger technology, specifically a foldable double-sided flexible solar charger. Background Technology

[0002] The foldable bi-sided flexible solar charger is an innovative outdoor power supply device that combines portability, high efficiency, and durability. It uses lightweight and flexible thin-film solar technology, allowing it to be easily rolled up or folded for easy carrying during outdoor activities such as hiking and camping. Its core highlight is its unique bi-sided power generation design, where the front directly absorbs sunlight while the back captures reflected light from the ground and scattered light from the environment, thus significantly improving energy capture efficiency and increasing power generation by up to 25% compared to traditional single-sided products. Combined with a high-efficiency charging control circuit, it can quickly charge various USB devices such as mobile phones, power banks, and GPS devices. According to a patent published on the China Patent Network, the patent title is "A Foldable Solar Charger," patent application number 200920318454.8. Most existing foldable solar chargers use a rigid box structure, which is inconvenient to carry and can easily cause injury. This utility model uses a flexible material as the base layer and a USB terminal as the output interface, making it more convenient and safer to carry, and with a wider range of applications. The key technical points are: solar cell modules are fixed at intervals on a foldable flexible base layer, and the output interface is a USB junction box with a built-in voltage regulator circuit. However, the aforementioned foldable solar charger requires tightening the four corner screws to prevent shrinkage when unfolded, and the tightening and locking method is too cumbersome, requiring individual screws to be tightened sequentially, greatly affecting the convenience of locking.

[0003] Therefore, the design of foldable solar chargers needs to be modified to effectively prevent the problem of them being too cumbersome to unfold and lock. Utility Model Content

The protective mechanism 12 includes two fixed seats 13. The outer side of the fixed seat 13 is movably connected to the irregular plate 14 through a rotating shaft. The side of the irregular plate 14 away from the fixed seat 13 is fixedly connected to the protective cover 15. The back of the protective cover 15 is located on the front of the quick locking mechanism 3.

[0022] As a technical optimization of this utility model, the protective mechanism 12 can protect the quick locking mechanism 3 and prevent dust from falling on it.

[0023] refer to Figure 4 An insert rod 16 is provided through the inner side of the outer side of the irregular plate 14, and the back of the insert rod 16 extends into the interior of the locking rod 10.

[0030] As a technical optimization of this utility model, the L-shaped rod 19 makes it easier for users to pull the insertion rod 16, thus increasing user convenience.

[0031] The working principle and usage process of this utility model are as follows: First, it should be noted that this charger adopts the MPPT protocol, BMS, communication, overcharge, over-discharge, and thermal runaway management protocol, and uses a bidirectional inverter; the discharge voltage is 12V boosted to 380V and then stepped down to 220V / 100V output, and the charging voltage is 220V / 100V stepped down to 12V-52V, using an AC to DC charging management protocol; then, the user unfolds the flexible solar panel charging component 1 and flexible solar panel charging component 2, which are connected by hinges, so that they are at a suitable unfolding angle for subsequent operation. The user holds the hook 9 and pulls it outward. The hook 9 drives the pulling rope 8, which in turn drives the moving plate 7 to move outward against the elastic force of the spring 6. As the moving plate 7 moves outward, the locking rod fixed on the inner side of the moving plate 7... 10 then moves outward. When it reaches the appropriate position, the inner side of the locking rod 10 is aligned with the inside of the recessed frame 4 and inserted to achieve initial locking. The hook 9 on the outside of the pull rope 8 is hung on the inside of the hook ring 11 on the front of the flexible solar panel charging component 1 or the flexible solar panel charging component 2 to keep the locking rod 10 stable in the recessed frame 4, so that the locking effect can be quickly unfolded. Then, the irregular plate 14 located in the protective mechanism 12 on both sides of the front of the recessed frame 4 is rotated by hand. The irregular plate 14 rotates around the fixed seat 13 through the rotating shaft, driving the protective cover 15 to move towards the front of the quick locking mechanism 3. When the protective cover 15 moves to the appropriate position and covers the front of the quick locking mechanism 3, the insertion rod 16 is passed through the inner side of the outer side of the irregular plate 14 and inserted into the inside of the locking rod 10 to further fix the locking rod 10 and enhance the locking effect.

[0032] In summary, this foldable double-sided flexible solar charger changes the traditional method of sequentially tightening locking bolts after unfolding. Instead, it uses a locking rod 10 that engages inside the recessed frame 4 for quick locking, increasing the convenience and efficiency of locking.
