Abstract
Description
Technical Field
[0001] This utility model relates to an airfoil solar panel deployment mechanism. Background Technology
[0002] Commercially available mobile lighting vehicles, limited by space, cost, and portability, typically only have 1-3 solar panels (each with a power output of approximately 150-300W). The number of solar panels directly affects the system's charging efficiency. Under the same sunlight conditions, increasing the number of panels can shorten the charging time of the energy storage battery. This characteristic is particularly crucial in scenarios with short periods of sunshine (such as high-latitude regions or tropical rainy areas). If the effective continuous sunlight in the local area is only 2-5 hours, it is necessary to reasonably increase the number of solar panels or improve the power density of each panel to ensure that the energy storage system (usually with a capacity of 3-6kWh) is fully charged within a limited time, avoiding nighttime lighting interruptions due to insufficient power. At the same time, increasing the number of solar panels will increase the space occupied by the mobile lighting vehicle, which is not conducive to transportation and storage. Utility Model Content
[0003] This invention addresses the aforementioned problem by providing an airfoil solar panel deployment mechanism. By cleverly utilizing a combination of telescopic and folding methods, it enables the deployment and retraction of multiple solar panels, thereby improving power generation efficiency. Simultaneously, it facilitates folding and storage while occupying a small area.
[0004] This utility model is constructed as follows: it includes a retractable rod fixing frame and a central solar panel disposed on the surface of the retractable rod fixing frame. The retractable rod fixing frame is symmetrically arranged with multi-stage sleeve-type telescopic arm assemblies on both sides. Each multi-stage sleeve-type telescopic arm assembly on each side has multiple foldable or unfoldable side solar panel groups in the middle. Each side solar panel of the side solar panel group is hinged to each telescopic rod of the multi-stage sleeve-type telescopic arm assembly. The innermost side solar panel of the side solar panel group is connected to the retractable rod fixing frame via a lifting and sliding assembly.
[0005] Furthermore, the lifting and sliding assembly includes four columns located at the bottom of the fixed frame, and a liftable sliding crossbeam is provided between the columns located at the front and rear on each side. The front and rear ends of the sliding crossbeam are slidably engaged with the front and rear columns, and the innermost side solar panel of the side solar panel assembly is hinged to the sliding crossbeam.
[0006] Furthermore, the multi-stage sleeve-type telescopic boom assembly includes multiple telescopic rods that are sequentially sleeved together, with adjacent telescopic rods having a telescopic fit, wherein the smaller telescopic rod can telescopically fit with the adjacent larger telescopic rod.
[0007] Furthermore, the plurality of telescopic rods includes a first telescopic rod, a second telescopic rod, and a third telescopic rod. The first telescopic rod is sleeved inside the second telescopic rod and can extend and retract along the length of the second telescopic rod. The second telescopic rod is sleeved inside the third telescopic rod and can extend and retract along the length of the third telescopic rod.
[0008] Furthermore, the side solar panel assembly includes multiple solar panels, adjacent solar panels are hinged together, and the front and rear of each solar panel are hinged to a telescopic rod of a multi-stage sleeve telescopic arm assembly.
[0009] Furthermore, the plurality of solar panels include a first solar panel, a second solar panel, and a third solar panel, wherein the middle portion of the first solar panel is hinged to the outer end of the first telescopic rod, the middle portion of the second solar panel is hinged to the outer end of the second telescopic rod, and the middle portion of the third solar panel is hinged to the outer end of the third telescopic rod.
[0010] Furthermore, the inner side of the column is provided with a slide rail along its length, and a slider is provided in the slide rail, the slider being connected to the sliding crossbar.
[0011] Compared with the prior art, this utility model has the following advantages: The device is reasonably designed, simple in structure, and easy to use. When the solar panel unfolding mechanism needs to be opened, the multi-stage sleeve telescopic arm assembly is manually pulled to extend each telescopic rod longitudinally to the preset length. During the extension of each telescopic rod, the sliding crossbar also moves upward synchronously along the slide rail of the column. When the sliding crossbar reaches the top travel position, the hinge pulls the side solar panel group to fully unfold along the hinge axis. Each side solar panel and the middle solar panel form a planar array and are in the same planar unfolded state. When the solar panel unfolding mechanism is folded: the side solar panel groups on both sides are manually pushed, and each side solar panel is reset by the reverse folding thrust of the hinge, and the layers are compressed to the initial compact shape. The cables are retracted without interference throughout the process. During this process, as each telescopic rod retracts, each telescopic rod of the multi-stage sleeve telescopic arm assembly retracts longitudinally to the minimum length, and the sliding crossbar also moves downward synchronously along the slide rail of the column.
[0012] When folded, the volume of this device can be reduced to 1 / 5 to 1 / 8 of its unfolded state, making it suitable for standard cargo box transportation and storage in narrow spaces. The ultra-compact folding design allows for convenient transportation without disassembly. Due to the increased number of solar panels, the ultra-large photovoltaic area significantly improves the overall power generation capacity of the solar panels. Attached Figure Description

[0020] When the solar panel unfolding mechanism is opened: by manually pulling the multi-stage sleeve telescopic arm assembly, each telescopic rod is extended longitudinally to the preset length section by section. During the extension of each telescopic rod, the sliding crossbar also moves upward synchronously along the slide rail of the column.

During this process, as each telescopic rod retracts, each telescopic rod of the multi-stage sleeve telescopic arm assembly will retract longitudinally to the minimum length section by section, and the sliding crossbar will also move downward synchronously along the slide rail of the column.

[0024] The aforementioned column has a slide rail 53 along its length on its inner side, and a slider 54 is provided in the slide rail, which is fixedly connected to the sliding crossbar.

[0026] In this embodiment of the utility model, taking three telescopic rods as an example, the three telescopic rods include a first telescopic rod 32, a second telescopic rod 33 and a third telescopic rod 34.
