[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0026] Reference Figures 1-6 A portable, foldable solar panel includes a back plate 7, scissor arms, and solar panels. The back plate 7 has two sets of parallel mounting brackets, and a motor 3 is fixedly connected to the mounting brackets. The output end of the motor 3 is connected to a lead screw 6. The two rods on the same side of the scissor arms are respectively hinged to a fixed base and a sliding base 2. The fixed base is fixedly connected to the mounting brackets, and the sliding base 2 has a threaded hole. The lead screw 6 is adapted to the sliding base 2 through the threaded hole. Multiple solar panels are arranged between the two scissor arms.

[0027] Motor 3 drives sliding seat 2 to slide up and down via lead screw transmission, thereby driving the scissor arm to unfold and extend, thus realizing the unfolding and angle adjustment of solar panel.

[0028] The solar panels are made of PETG material and are 3D printed, making them lightweight and durable.

[0029] In other preferred embodiments, the mounting bracket includes an upper fixing plate and a lower fixing plate 5, both of which are fixedly connected to the back plate 7. The motor 3 is fixedly connected to the upper fixing plate, and a through hole is provided on the lower fixing plate 5, with a lead screw 6 rotatably connected within the through hole. The fixing base and the lower fixing plate are integrally formed.

[0030] Each of the upper and lower fixed plates has a limit switch to prevent the motor from being overloaded or exceeding its operating range.

[0031] In other preferred embodiments, the scissor arm includes a first link group and a second link group. The first link group includes a plurality of first rods 1 that are hinged in sequence, and the second link group includes a plurality of second rods 4 that are hinged in sequence. The first rods 1 and the second rods 4 are hinged together. The end of the first rod 1 is hinged to the sliding seat 2, and the end of the second rod 4 is hinged to the fixed seat. The end of the solar panel is fixedly connected to the first rod 1.

[0032] In other preferred embodiments, the solar panel includes a frame and a panel. Two sets of frames are symmetrically arranged on both sides of the panel, and the panel is connected to the scissor arms via the frames. Connection holes are provided at the frames for connecting the scissor arms.

[0033] In other preferred embodiments, a synchronous pulley 8 is provided at the end of the lead screw 6, and the synchronous pulleys 8 on the two lead screws 6 are connected by a synchronous belt 9.

[0034] The working principle of this utility model is as follows: After the motor 3 starts, it drives the sliding seat 2 to slide up and down through the lead screw transmission. The movement of the sliding seat 2 is transmitted to the solar panel through the scissor arm. The solar panel unfolds under the control of the first linkage group, and the first linkage group drives the other solar panels to unfold in sequence. The second linkage group ensures that the solar panel remains stable during the unfolding process through the rotating joint. Conversely, when the motor 3 starts in the reverse direction, it drives the sliding seat 2 to slide in the reverse direction through the lead screw transmission. The movement of the sliding seat 2 is transmitted to the solar panel through the first linkage group. The solar panel retracts through the rotating joint, driving the other solar panels to retract in sequence. The second linkage group ensures that the solar panel remains stable during the retraction process through the rotating joint.

[0035] This design not only ensures the stability of the solar panels during unfolding and retraction, but also makes them small, lightweight, and easy to carry through a compact folding design and the use of lightweight materials. Furthermore, the automated transmission system simplifies operation, improves portability and flexibility, and makes them suitable for various outdoor activities and emergency scenarios.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
