Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically a foldable photovoltaic support. Background Technology

[0002] Existing commercially available folding photovoltaic (PV) support systems include drawer-style systems. These systems stack multiple PV panels inside a box like drawers, resulting in compact storage. However, there's no linkage mechanism between the panels, requiring them to be pushed and pulled one by one, leading to low operational efficiency. Furthermore, the panels are partially or completely exposed outside the box, making them vulnerable to bumps and knocks during transport, offering poor protection. Additionally, unfolding and folding cannot be done in one operation, requiring multiple pulls on-site, increasing labor intensity. Once unfolded, the panels lack reliable locking mechanisms, making them prone to swaying in windy conditions, affecting power generation efficiency and safety. Therefore, the market urgently needs a compact folding PV support system that allows for simultaneous unfolding / folding of multiple PV panels with a single hand operation, folds into a neat box, and is locked in place when unfolded. This would solve the problems of cumbersome operation, large storage volume, weak protection, and poor reliability inherent in existing technologies. Utility Model Content

[0019] Advantageously, the ends of the first photovoltaic panel 12 and the second photovoltaic panel 34 are provided with handles 52, which facilitate personnel to use their hands to hold and pull the first photovoltaic panel 12 and the second photovoltaic panel 34.

[0020] Advantageously, the housing 11 is provided with a sliding hole 51 on the left and right sides, through which the first photovoltaic panel 12 and the second photovoltaic panel 34 slide out or slide in.

[0021] Advantageously, the guide rail assembly includes a sliding groove 13 fixedly disposed on the front and rear sides of the first photovoltaic panel 12 and the second photovoltaic panel 34. The front and rear end walls inside the housing 11 are fixedly disposed on the upper side of the first guide rail 29, which is slidably connected to the sliding groove 13 on both sides of the second photovoltaic panel 34. The front and rear end walls inside the housing 11 are fixedly disposed on the lower side of the second guide rail 44, which is slidably connected to the sliding groove 13 on both sides of the first photovoltaic panel 12.

[0022] Advantageously, the linkage component includes a rotating seat 22 fixedly disposed in the middle position inside the housing 11. A first rod 21 is rotatably disposed at the end of the rotating seat 22 and located on the lower side. A second rod 23 is fixedly disposed on the right side of the first rod 21, one above and one below. An iron roller 25 is rotatably disposed between the second rods 23. A first slider structure is disposed between the first rod 21 and the first photovoltaic panel 12. A second slider structure is disposed between the second rod 23 and the second photovoltaic panel 34. The housing 11 is also provided with a guide and limiting structure that guides and limits the iron roller 25. The first rod 21 and the second rod 23 form a lever structure. Through the linkage of the rotating seat 22, the first photovoltaic panel 12 and the second photovoltaic panel 34 can achieve synchronous reverse movement.

[0023] Advantageously, the first slider structure includes a second shaft 42 fixedly disposed at the end of the first rod 21, a second slider 45 rotatably disposed on the outer surface of the second shaft 42, a second groove 41 disposed in the first photovoltaic panel 12, and the second slider 45 being inserted into the second groove 41 and slidably connected with the second groove 41.

[0024] Advantageously, the second slider structure includes a first shaft 26 fixedly disposed on the upper end of the upper second rod 23, a first slider 24 rotatably disposed on the outer surface of the first shaft 26, a first groove 28 disposed in the second photovoltaic panel 34, and the first slider 24 being inserted into the first groove 28 and slidably connected with the first groove 28.

[0025] Advantageously, the guide limiting structure includes an intermediate plate 31 fixedly installed inside the housing 11, an inner groove 32 is provided inside the intermediate plate 31, and arcs 33 are provided at both ends of the inner groove 32. The iron roller 25 rolls and abuts against the inner groove 32 and the arcs 33. The first rod 21 is located on the lower side of the intermediate plate 31, and the second rod 23 is located on the upper and lower sides of the intermediate plate 31 respectively.

[0026] Beneficially, among which, such as Figure 2As shown, a magnet is fixedly installed inside the arc 33. When the iron roller 25 moves into the arc 33, the iron roller 25 is magnetically fixed. Only when the first photovoltaic panel 12 and the second photovoltaic panel 34 are pushed vigorously by personnel can a reverse force be generated to separate the iron roller 25 from the magnet.

[0027] Beneficially, when the iron roller 25 is located within the arc 33, it is stopped by a limit.

[0028] Beneficially, the inner groove 32 is mushroom-shaped, and the arc surface of the inner groove 32 rolls and abuts against the iron roller 25.

[0029] After pulling the first photovoltaic panel 12 or the second photovoltaic panel 34, personnel can easily pull the second photovoltaic panel 34 or the first photovoltaic panel 12 out of the housing 11 through the linkage component.

[0030] The first photovoltaic panel 12 is provided with sliding grooves 13 on both sides. The sliding grooves 13 are slidably connected to the second guide rail 44, so that the first photovoltaic panel 12 can be guided to slide.

[0031] The second photovoltaic panel 34 is provided with sliding grooves 13 on both sides. The sliding grooves 13 are slidably connected to the first guide rail 29, so that the second photovoltaic panel 34 can be guided to slide.

[0032] The first rod 21 and the second rod 23 form an integrated component and rotate around the rotating seat 22. A first slider 24 is rotatably provided on one side of the second rod 23 and is slidably connected to the first groove 28. A second shaft 42 is rotatably provided on one side of the first rod 21 and is slidably connected to the second groove 41. Therefore, the first photovoltaic panel 12 and the second photovoltaic panel 34 can simultaneously extend or retract into the housing 11 under the action of the connecting rod, slider and groove structure. The upper and lower layered structure design helps to hide most of the second photovoltaic panel 34 and the first photovoltaic panel 12 inside the housing 11, making the photovoltaic bracket smaller and more compact.

[0033] By setting an intermediate plate 31 and an inner groove 32, the iron roller 25 rolls against the arc surface of the inner groove 32, and then the arc 33 limits the iron roller 25. On the one hand, the iron roller 25 provides inertia, so that the first rod 21 and the second rod 23 can rotate more smoothly through inertia.

[0034] like Figure 2-5 As shown, when the first photovoltaic panel 12 and the second photovoltaic panel 34 are extended or retracted to their limit positions, the iron roller 25 is just caught and abutted by the arc 33, thus realizing the limiting function. The magnet inside the arc 33 is used to attract the iron roller 25, enhancing the limiting stability in the unfolded and stored state.

[0035] The handle 52 makes it easy for personnel to pull the first photovoltaic panel 12 and the second photovoltaic panel 34 by hand.

[0036] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without creative effort should be included within the protection scope of this utility model; therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
