Description

Technical Field

[0001] This application relates to the field of foldable solar panel technology, and in particular to a solar panel auxiliary unfolding structure. Background Technology

[0002] Foldable solar panels are increasingly used due to their ease of storage and transport when folded, and their ability to provide high power generation when unfolded. These devices typically consist of multiple solar panels and a base with storage racks on the base to secure the folded solar panel assembly.

[0003] For example, patent application number CN202322087020.4 discloses a typical foldable solar energy device. In this device, foldable solar panel assemblies are mounted on a base and secured by a storage rack on the base. To facilitate unfolding and folding, each solar panel is equipped with wheels at its bottom, and the base has a channel for the wheels to enter and exit.

[0004] However, such existing structures have a significant drawback during deployment: in the initial stage of deployment (i.e., when the solar panel module just begins to move outward from the base and the deployment angle is still small), the entire solar panel module tends to tilt forward and risks falling over. This instability not only poses serious safety hazards and can easily lead to accidents if not handled properly, but it also easily damages the solar panel itself. Utility Model Content

[0005] To reduce safety hazards during the deployment of solar panel modules, this application provides an auxiliary deployment structure for solar panels.

[0006] This application provides a solar panel auxiliary deployment structure, which adopts the following technical solution:

[0007] A solar panel deployment aid structure includes an auxiliary plate hinged to a base and located at the access point for solar panel rollers. The auxiliary plate includes an uphill section, a downhill section, and a horizontal transition section between the two, with the uphill section of the auxiliary plate positioned close to the base.

[0008] By adopting the above technical solution, an auxiliary plate with uphill and downhill slopes is added to both sides of the frame. When the solar panels are pushed outward, at a relatively small angle, the uphill slope causes the solar panels to tend to tilt backward, meaning the center of gravity is towards the storage direction, reducing the risk of them falling directly forward. At the horizontal transition section, a stable platform is provided, ensuring the rollers can move smoothly after climbing, avoiding new instability caused by sudden descent. At this point, a sufficient angle has been formed between adjacent solar panels, providing mutual support, and the structure itself has become stable. The downhill section helps the rollers descend smoothly to contact the ground, completing the deployment. This effectively avoids the risk of the solar panel assembly tilting forward and falling during the initial deployment stage in existing technologies, reducing safety hazards and the possibility of damage to the solar panels themselves, and improving the safety of the deployment process.

[0009] Optionally, one end of the auxiliary plate is fixed with a rotating shaft, and the base is fixed with two sets of hinge seats at the hinge joint of the auxiliary plate. The rotating shaft of the auxiliary plate is rotatably connected between the two sets of hinge seats. The hinge seat includes two threaded sleeves fixedly installed on the base. The end of the rotating shaft is located between the two threaded sleeves, and an upper baffle is fixed between the two threaded sleeves by bolts.

[0010] By employing the above technical solution, the rotating shaft is confined between two threaded sleeves, preventing it from coming off upwards or downwards. The bolted connection facilitates disassembly, making it convenient for later maintenance or replacement of the auxiliary plate / rotating shaft. This enhances the reliability and durability of the entire hinge structure.

[0011] Optionally, a side baffle is fixed to the outer side of the upper baffle, and the side baffle blocks the axis of the rotating shaft to prevent the rotating shaft from moving axially.

[0012] By adopting the above technical solution, axial movement of the auxiliary plate is prevented during use, ensuring its precise and stable position.

[0013] Optionally, reinforcing ribs are fixed inside the auxiliary plate at the uphill section, downhill section, and horizontal transition section.

[0014] By adopting the above technical solution, the overall structural strength of the auxiliary plate has been enhanced.

[0015] Optionally, the storage rack on the base is provided with a limiting component to restrict the auxiliary plate from folding outward when it is folded upward for storage.

[0016] By adopting the above technical solution, the auxiliary panel is prevented from accidentally flipping out during storage, ensuring the compactness and stability of the auxiliary panel after storage, facilitating storage and transportation, and avoiding potential damage to surrounding personnel and equipment caused by the auxiliary panel flipping out, thereby improving the safety and ease of use of the entire foldable solar device.

[0017] Optionally, the limiting component includes a limiting plate hinged to the storage rack, and a positioning block is fixed on the limiting plate. When the positioning block is used to contact the storage rack, it prevents the limiting plate from disengaging from the outward flipping path of the auxiliary plate under its own weight.

[0018] By adopting the above technical solution, the limiting plate can rotate around its hinge axis. When the auxiliary plate is folded upwards and stored in place, the operator needs to manually flip the limiting plate to a certain angle so that it blocks the outside of the auxiliary plate and prevents the auxiliary plate from flipping outwards and falling.

[0019] In summary, this application includes at least one of the following beneficial effects:

[0020] 1. In the initial stage of solar panel assembly deployment, the uphill section causes the solar panel to tend to tilt backward, with the center of gravity facing the storage direction. This effectively solves the problem of the solar panel assembly tilting forward and falling down as a whole in the initial stage of deployment in the existing technology, making the deployment process more stable and smooth.

[0021] 2. The limiting components on the storage rack can effectively prevent the auxiliary plate from accidentally flipping outwards during storage. Attached Figure Description

Detailed Implementation

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] This application discloses a solar panel assisted unfolding structure, which aims to solve the problem that solar panel components in existing foldable solar devices are prone to tilting forward and falling down in the initial stage of unfolding. The structure design is optimized to improve the safety and stability of the unfolding process.

[0030] Reference Figure 1 , 2 The solar panel deployment auxiliary structure includes an auxiliary plate 1, which serves as the core support component and is hinged to the solar panel module channel opening of the base 2 to provide transition support during the deployment of the solar panel module.

[0031] Reference Figure 2 The auxiliary plate 1 has a three-section structure, including an uphill section 3, a horizontal transition section 4, and a downhill section 5 connected in sequence. The uphill section 3 is located on the side closer to the base 2, with one end hinged to the base 2 and the other end smoothly transitioning to the horizontal transition section 4. The horizontal transition section 4 is located in the middle of the entire auxiliary plate 1, providing a stable transition support surface for the rollers of the solar panel assembly. The downhill section 5 is connected to the side of the horizontal transition section 4 away from the uphill section 3, with its end extending towards the ground, facilitating a smooth transition of the rollers of the solar panel assembly from the auxiliary plate 1 to the ground. In practical applications, the tilt angle of the uphill section 3 can be designed according to the weight, size, and deployment requirements of the solar panel assembly, ensuring that the solar panel assembly forms a backward center of gravity trend in the initial stage of deployment, while avoiding excessively steep slopes that would make it difficult for the rollers to climb.

[0032] In the initial stage of solar panel deployment, due to the presence of the uphill section 3, when the solar panel is pushed outward at a small deployment angle, it tends to tilt backward, with its center of gravity facing the storage direction. This effectively avoids the risk of the solar panel assembly tilting forward and falling over during the initial deployment stage, as is common in existing technologies. When the solar panel assembly moves to the horizontal transition section 4, this section provides a stable platform for the rollers, ensuring smooth movement after the rollers have climbed and preventing new instability caused by sudden descent. At this point, a sufficient angle has been formed between adjacent solar panels, providing mutual support and stabilizing the structure. Finally, the downhill section 5 helps the rollers descend smoothly to contact the ground, completing the solar panel assembly deployment process and making the entire deployment process smoother and more stable.

[0033] Reference Figure 3 A rotating shaft 6 is fixed to one end of the auxiliary plate 1 near the base 2. The rotating shaft 6 can be made of stainless steel and is rigidly connected to the end of the auxiliary plate 1 by welding or other methods to ensure the connection strength. Two sets of hinge seats 7 are fixed to the edge of the corresponding solar panel module channel opening on the base 2. The two sets of hinge seats 7 are spaced apart along the width direction of the base 2 and correspond to the two ends of the rotating shaft 6 respectively.

[0034] Reference Figure 3 ,4 The hinge seat 7 includes two vertically arranged threaded sleeves 8, each with a cylindrical structure and an internal threaded groove. A limit ring 9 is fixed to one end of each threaded sleeve 8. The threaded sleeve 8 passes through the through hole of the base 2 from bottom to top, causing the limit ring 9 to abut against the lower end face of the base 2. Both ends of the rotating shaft 6 are respectively positioned between the two threaded sleeves 8 of the two sets of hinge seats 7, allowing the rotating shaft 6 to rotate freely around its own axis.

[0035] To limit the vertical displacement of the rotating shaft 6, an upper baffle 11 is fixed between the two threaded sleeves 8 by bolts 10. The upper baffle 11 can be made of steel plate, and its two ends are provided with mounting holes that match the threaded sleeves 8. After the bolts 10 pass through the mounting holes, they are threadedly connected to the threaded sleeves 8, thus fastening the upper baffle 11 to the top of the two threaded sleeves 8, thereby forming an upper limit position for the rotating shaft 6 and preventing the rotating shaft 6 from coming off upward. At the same time, a lower support for the rotating shaft 6 is formed at the corresponding position on the surface of the base 2 to prevent the rotating shaft 6 from falling downward.

[0036] To further enhance the stability of the hinge structure and prevent axial movement of the rotating shaft 6 during rotation, a side baffle 12 is fixed to the outer side of the upper baffle 11. The side baffle 12 is set perpendicular to the upper baffle 11, and its position corresponds to the end of the rotating shaft 6. When the rotating shaft 6 is installed in place, the inner side of the side baffle 12 abuts against the end of the rotating shaft 6 or leaves a small gap, thereby effectively blocking the movement of the rotating shaft 6 along its own axis and ensuring the stability of the auxiliary plate 1 during rotation.

[0037] Reference Figure 5 Because the auxiliary plate 1 needs to withstand significant pressure and impact during the deployment of the solar panel assembly, reinforcing ribs 13 are fixed inside the auxiliary plate 1 at the corresponding positions of the upslope section 3, horizontal transition section 4, and downslope section 5 to prevent bending or deformation. The reinforcing ribs 13 can be made of metal profiles, such as angle steel or channel steel. The reinforcing ribs 13 can be fixed to the inner wall of the auxiliary plate 1 by welding, further improving the rigidity and load-bearing capacity of the overall structure.

[0038] Reference Figure 5 When the solar panel assembly is stored in the base 2, the auxiliary panel 1 can be folded upwards to reduce the space occupied. To prevent the auxiliary panel 1 from accidentally flipping outwards due to vibration or accidental contact while in the stored state, the storage rack 14 of the base 2 is equipped with a corresponding limiting component 15.

[0039] Reference Figure 5 The limiting component 15 includes a limiting plate 16 and a positioning block 17. The limiting plate 16 is hinged to the side of the storage rack 14 near the folding path of the auxiliary plate 1 via a hinge shaft, and can rotate freely around the hinge shaft. The positioning block 17 is fixed to one side of the limiting plate 16, and its shape is adapted to the corresponding contact part of the storage rack 14.

[0040] After the auxiliary plate 1 is folded upwards to the storage position, the operator can rotate the limiting plate 16 to flip it to a position where it abuts against the outside of the auxiliary plate 1. At this time, the positioning block 17 contacts the surface of the storage rack 14, forming a support for the limiting plate 16 and preventing the limiting plate 16 from rotating away from the auxiliary plate 1 under its own weight or transportation vibration. This reliably blocks the outward flipping path of the auxiliary plate 1, ensuring that the auxiliary plate 1 is stably stored. When it is necessary to unfold the auxiliary plate 1, simply rotate the limiting plate 16 in the opposite direction to disengage the positioning block 17 from the storage rack 14, thus releasing the restriction on the auxiliary plate 1.

[0041] In other embodiments, the limiting component 15 may also be replaced by a magnet, a suction cup, or the like.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
