Description

Technical Field

[0001] This invention belongs to the field of photovoltaic power generation technology, and specifically relates to a quick-installation bracket for foldable solar photovoltaic panels. Background Technology

[0002] Photovoltaic power generation (solar power generation) is a technology that uses the photovoltaic effect of semiconductor materials to directly convert solar energy into electrical energy. Its core background technologies cover multiple fields such as materials science, semiconductor physics, power electronics, and system integration. In addition to the power generation equipment, the mounting brackets for installing the power generation equipment also play a crucial role. Solar photovoltaic panel mounting brackets are an important component of photovoltaic systems, and their design, selection, and installation directly affect power generation efficiency, system stability, and service life. There are many types of brackets, which are mainly divided into RV roof brackets, ground brackets, and special scene brackets according to the application scenario. Among them, special scene brackets are the least used due to their special structure, while ground brackets are mostly required for large areas of uninhabited flat land, so their application is also relatively rare. RV roof photovoltaic panel mounting brackets are widely used on RVs, but the RV roof solar brackets seen on various RV roofs still need improvement.

[0003] Existing support structures, while prioritizing safety, often involve customizing adaptive structural solutions based on common RV roof environments to ensure stable operation, thus reducing market competitiveness. Similarly, for safety, wind resistance, and waterproofing, companies frequently opt for higher-strength materials and more robust connection structures, increasing production costs and reducing installation convenience, further diminishing market competitiveness. Furthermore, the orientation and angle of photovoltaic panels are fixed after installation, wasting daytime sunlight. In areas with significant obstructions, this fixed structure severely restricts the installation range, increasing the difficulty of use and reducing power generation efficiency, again lowering market competitiveness. Existing supports are often transported in loose components for installation, increasing the risk of errors and significantly extending installation time. In certain locations, prolonged personnel stay is not feasible, greatly increasing safety risks and installation costs, thus reducing market competitiveness. Therefore, this invention optimizes and improves existing support structures to address these issues. Summary of the Invention

[0004] This invention overcomes the shortcomings of existing technologies and proposes a foldable quick-installation bracket for solar photovoltaic panels; it solves the problems of current RV roof photovoltaic panel mounting brackets requiring customization, which increases production costs; fixed angles reducing power generation efficiency; flat photovoltaic panels increasing the difficulty of weather resistance; and slow disassembly and assembly increasing the difficulty of installation.

[0014] The beneficial effects of this invention compared to the prior art are as follows:

[0015] 1. This invention fixes the bracket to the roof of the RV, and adjusts the level of the turntable frame in real time during RV travel to adapt to RV shaking and absorb high-frequency vibrations from uneven road surfaces, improving the bracket's stability and adaptability. This effectively solves the problems of bracket tilting and parts falling off caused by excessive shaking and high-frequency vibrations during RV travel, avoiding safety accidents and achieving stable operation of the bracket in unstable environments. Furthermore, the angle adjustment component adjusts the angle of the photovoltaic panel to ensure that the photovoltaic panel always faces the sun, improving power generation efficiency and effectively avoiding the problem of insufficient effective sunlight time due to the installation location and the special structure of the RV roof, achieving the ability to install at will.

[0016] 2. The installation mechanism ensures stable mounting of the photovoltaic panels on the bracket, and the unfolding angle can be adjusted according to the environment. This ensures that under good weather conditions, the bracket can maximize power generation efficiency when used on the vehicle roof, while minimizing wind and rain damage in windy or rainy weather, improving wind resistance and waterproofing. This effectively solves the problem of increased costs caused by using higher strength materials and more stable connection structures, achieving a bracket with a large unfolding surface while also possessing strong wind resistance and waterproofing capabilities. Through the cooperation of the installation mechanism and linkage mechanism, the bracket can be quickly assembled, disassembled, and folded into a compact structure with a small volume, improving portability and effectively solving the problems of difficult assembly, disassembly, or transportation difficulties caused by the large size of existing brackets. This enables the bracket to be used immediately after disassembly and is easy to transport. Ultimately, this solves the problems of existing bracket structures requiring customization, increasing production costs, fixed angles reducing power generation efficiency, flat photovoltaic panels increasing the difficulty of wind and rain resistance, and slow assembly and disassembly increasing installation difficulty.

A sliding sleeve 8 is slidably fitted onto the outside of the limiting ring. The upper opening of the sliding sleeve 8 is smaller than the inner diameter of the inner wall of the sliding sleeve 8. The outer surface of the limiting ring maintains sliding contact with the inner wall of the sliding sleeve 8. A spring 7 is installed inside the sliding sleeve 8. The upper and lower ends of the spring 7 abut against the limiting ring and the inner bottom surface of the sliding sleeve 8, respectively, to absorb vibration. A second hinge frame is fixedly installed at the lower end of the sliding sleeve 8. A second hinge seat 9 is rotatably mounted on the second hinge frame. A threaded rod is fixedly installed at the lower end of the second hinge seat 9. A threaded sleeve 10 is screwed onto the outside of the threaded rod. A mounting plate 11 is fixedly installed at the lower end of the threaded sleeve 10, and a fixing hole is provided on the mounting plate 11.

[0036] A first level sensor 13 is fixedly installed on the gearbox 12, and a second level sensor 14 is fixedly installed on the turntable frame 1. The first level sensor 13 is used to detect the levelness in the X-axis direction, and the second level sensor 14 is used to detect the levelness in the Y-axis direction. Both the first level sensor 13 and the second level sensor 14 are liquid level sensors.

[0037] The upper surfaces of the two connectors 20 within the same mounting mechanism are inclined towards the side of the other mounting mechanism. A connector groove is provided on the upper surface of the connector 20. The flip box 21 is located on the upper surface of the connector 20, and its extension direction is perpendicular to the upper surface of the connector 20. A locking box 28 is fixedly installed at the lower end of the flip box 21, and an elastic pin 32 is fixedly installed on the lower surface of the locking box 28. The elastic pin 32 is inserted into the connector groove of the connector 20, thereby fixing the flip box 21 to the connector 20. The upper end of the flip rod 23 is rotatably connected to the upper end of the flip box 21 via a flip shaft 22.

[0038] The angle adjustment assembly includes a support rod 25, a sliding shaft 26, a second electric push rod 27, a rotating shaft 29, a locking plate 30, and a second motor 31.

[0039] A second electric actuator 27 is fixedly installed at the lower end of the interior of the flip box 21. The axis of the second electric actuator 27 is parallel to the extension direction of the flip box 21, and one end of the piston rod of the second electric actuator 27 faces upward.

A support shaft 24 is fixedly installed at the middle of the lower end of the flip rod 23. A support rod 25 is installed between the support shaft 24 and the sliding shaft 26. One end of the support rod 25 is hinged to the support shaft 24, and the other end of the support rod 25 is hinged to the sliding shaft 26. When the piston rod of the second electric actuator 27 retracts, the flip rod 23 retracts into the interior of the flip box 21 under the action of the support rod 25; when the piston rod of the second electric actuator 27 extends, the flip rod 23 rotates to the outside of the flip box 21 under the action of the support rod 25.

[0040] A second motor 31 is fixedly mounted on the outer surface of the locking box 28. A rotating shaft 29 is rotatably mounted inside the locking box 28, with one end of the rotating shaft 29 fixedly connected to the output shaft of the second motor 31. A locking plate 30 is fixedly mounted on the outer side of the rotating shaft 29. An opening is provided on the side wall of the upper side of the locking box 28, located on one side of the locking plate 30. When the flipping rod 23 is retracted into the flipping box 21, the second motor 31 controls the rotating shaft 29 to rotate. The rotating shaft 29 drives the locking plate 30 to rotate to the outside of the opening, and the locking plate 30 abuts against the lower end of the flipping rod 23, thereby locking the flipping rod 23.

[0041] The two flip rods 23 within the same installation mechanism remain parallel. Two threaded seats 33 are fixedly installed on the upper end face of each flip rod 23, with a bolt 34 screwed into each seat 33. A pressure plate 35 is sleeved on the outside of the bolt 34. When the photovoltaic panel 40 is placed on the two flip rods 23, the two pressure plates 35 on the two flip rods 23 are pressed against the two side edges of the photovoltaic panel 40, and the bolts 34 are tightened, thereby fixing the photovoltaic panel 40 to the two flip rods 23 of each installation mechanism.

[0042] The folding assembly includes pad rods 36, carriages 37, support blocks 38, and slide rods 39. A row of pad rods 36 is arranged between two flip rods 23 within the same mounting mechanism. The pad rods 36 are equidistant along the line connecting the two flip rods 23 and are parallel to the flip rods 23. The two outermost pad rods 36 are fixedly connected to the two flip rods 23 respectively. A carriage 37 is fixedly installed at both ends of each pad rod 36. A groove is provided inside each carriage 37, and the length of the groove is parallel to the length of the pad rod 36. A support block 38 is fixedly installed at the end of each pad rod 36 away from the other mounting mechanism. When a photovoltaic panel 40 is placed on the upper end of the two flip rods 23, the support block 38 on the row of pad rods 36 supports the lower end of the tilted photovoltaic panel 40. A slide bar 39 is provided between each pair of adjacent pad rods 36. A slider is fixedly provided at each end of the slide bar 39. The slider at one end of the slide bar 39 is slidably disposed in the slide groove of the slide frame 37 of the previous pad rod 36 near the other side of the mounting mechanism. The slider at the other end of the slide bar 39 is slidably disposed in the slide groove of the slide frame 37 of the next pad rod 36 away from the other side of the mounting mechanism.

[0043] When the folding assembly is in the folded state, the distance between two adjacent pad rods 36 is the smallest, and the angle between the pad rod 36 and the slide rod 39 is the smallest. When the folding assembly is in the working state, the distance between two adjacent pad rods 36 is the largest, and the angle between the pad rod 36 and the slide rod 39 is the largest.

[0044] The linkage mechanism includes four diagonal braces 41, one first folding rod 43, one second folding rod 44, two third folding rods 45, two fourth folding rods 46, one fifth folding rod 47, and one sixth folding rod 48.

[0045] A diagonal brace 41 is fixedly mounted on the lower side end face of each flip box 21 via a buffer pad 42. The length direction of the diagonal brace 41 is parallel to the extension direction of the flip box 21. The upper ends of the two diagonal braces 41 on the left are hinged to each other via a first connecting seat, and the upper ends of the two diagonal braces 41 on the right are hinged to each other via a second connecting seat. A first folding rod 43 is rotatably mounted on the first connecting seat, and a second folding rod 44 is rotatably mounted on the second connecting seat. The ends of the first folding rod 43 and the second folding rod 44 that are far apart from each other are hinged to the first connecting seat and the second connecting seat, respectively. The ends of the first folding rod 43 and the second folding rod 44 that are close to each other are hinged to each other via a third connecting seat. A third folding rod 45 is rotatably mounted on the lower end of each of the two front diagonal braces 41, and a fourth folding rod 46 is rotatably mounted on the lower end of each of the two rear diagonal braces 41. The ends of the third folding rod 45 and the fourth folding rod 46 on the left side that are far apart from each other are hinged to the lower ends of the two left diagonal braces 41, and the ends of the third folding rod 45 and the fourth folding rod 46 on the left side that are close to each other are hinged to each other through a fourth connecting seat 49. The ends of the third folding rod 45 and the fourth folding rod 46 on the right side that are far apart from each other are hinged to the lower ends of the two right diagonal braces 41, and the ends of the third folding rod 45 and the fourth folding rod 46 on the right side that are close to each other are hinged to each other through a fifth connecting seat. A fifth folding rod 47 is rotatably mounted on the fourth connecting seat 49, and a sixth folding rod 48 is rotatably mounted on the fifth connecting seat. The ends of the fifth folding rod 47 and the sixth folding rod 48 that are far apart from each other are hinged to the fourth connecting seat 49 and the fifth connecting seat respectively, and the ends of the fifth folding rod 47 and the sixth folding rod 48 that are close to each other are hinged to the sixth connecting seat 50.

[0046] When the linkage mechanism is in operation, the first folding rod 43 and the second folding rod 44 are on the same straight line, the third folding rod 45 and the fourth folding rod 46 on the same side are on the same straight line, and the fifth folding rod 47 and the sixth folding rod 48 are on the same straight line, with the first folding rod 43 and the fifth folding rod 47 being parallel. The two diagonal braces 41 on the left side, along with the third folding rod 45 and the fourth folding rod 46 on the left side, form an isosceles triangle, and the two diagonal braces 41 on the right side, along with the third folding rod 45 and the fourth folding rod 46 on the right side, form an isosceles triangle.

[0047] When the linkage mechanism is in the folded state, the angle between the two diagonal braces 41 on the same side remains minimal, the angle between the third folding rod 45 and the fourth folding rod 46 remains minimal, and the third folding rod 45 and the fourth folding rod 46 are retracted upwards between the two diagonal braces 41 on the same side, respectively contacting the two diagonal braces 41 on the same side. The angle between the first folding rod 43 and the second folding rod 44 remains minimal, and the angle between the fifth folding rod 47 and the sixth folding rod 48 remains minimal. The distance between the diagonal braces 41 on the left and right sides remains minimal.

[0048] This invention also proposes a method for using a quick-installation bracket for foldable solar photovoltaic panels, comprising the following steps:

[0049] Step 1: Before use, the rotating box 21 and the connector 20 are disconnected from each other, and the photovoltaic panel 40 is disconnected from the installation mechanism. The rotating rod 23 is located inside the rotating box 21, and the locking plate 30 locks and fixes the rotating rod 23. The folding assembly between the two rotating boxes 21 is in a folded state, the linkage mechanism is in a folded state, and the distance between the two rotating boxes 21 is minimized. Prepare all components and bring them to the designated location to prepare for installation.

[0050] Step two: At the start of installation, the leveling mechanism and turntable frame 1 are on the same horizontal plane. Hold the support column 4 and rotate the leveling mechanism downwards to keep it vertical. Then, lock the locking mechanism between the first hinge frame 2 and the first hinge seat 3. Then, rotate each sliding sleeve 8 to adjust the lower end face of each mounting plate 11 to fit against the mounting surface. Then, drive expansion bolts 34 into the fixing holes of the mounting plate 11 to fix the mounting plate 11 to the roof of the RV. Next, rotate the threaded sleeve 10 to adjust the height of the second hinge seat 9 to prevent the turntable frame 1 from bottoming out when the first electric actuator 5 is at its minimum length. Then, activate all the first electric actuators 5 and adjust the piston rod extension of each first electric actuator 5 using data from the first level sensor 13 and the second level sensor 14 to keep the turntable level.

[0051] Step three: The worker holds the two flip boxes 21 with both hands and pulls them outwards, causing them to move away from each other. During this pulling process, the distance between the pad rods 36 gradually increases, and the angle between the sliding rod 39 and the pad rods 36 gradually increases. Simultaneously, the linkage mechanism gradually unfolds. The first folding rod 43 and the second folding rod 44 gradually align themselves on the same straight line, as do the fifth folding rod 47 and the sixth folding rod 48, and the third folding rod 45 and the fourth folding rod 46 on the same side. Once the linkage mechanism is fully unfolded, the four flip boxes 21 are adjusted to their working angles, and the unfolded linkage mechanism supports the four flip boxes 21.

[0052] Step 4: Insert the elastic pins 32 on the four flip boxes 21 into the four sockets 20 respectively, thereby fixing the two mounting mechanisms to the turntable. Then, place the photovoltaic panel 40 on the flip rods 23 and pads 36 of the two sets of mounting mechanisms, so that the lower end of the photovoltaic panel 40 is supported by a row of support blocks 38. Then, rotate the four pressure plates 35 to the upper edge of both sides of the photovoltaic panel 40 and tighten the bolts 34, so that the four pressure plates 35 press and fix the photovoltaic panel 40.

[0053] Step 5: When the weather is sunny, the piston rod of the second electric push rod 27 extends, causing the sliding shaft 26 to slide upward inside the flip box 21. This drives the support rod 25 to lift the flip rod 23, which rotates upward around the flip shaft 22. Finally, the two photovoltaic panels 40 unfold horizontally, ensuring maximum light-receiving area. Simultaneously, the first motor 15 drives the worm gear 16 to rotate, which in turn drives the worm wheel 17 to rotate. The worm wheel 17 drives the drive gear 18 to rotate, which in turn drives the driven gear ring 19 to rotate. The driven gear ring 19 then drives the turntable to rotate, which in turn drives the installation mechanism and the two photovoltaic panels 40 to rotate horizontally, thus ensuring maximum sunshine duration and greatly improving power generation capacity. When the weather is windy or rainy, the piston rod of the second electric push rod 27 retracts, causing the sliding shaft 26 to slide downward inside the flip box 21. This drives the support rod 25 to pull the flip rod 23 downward, which rotates downward around the flip shaft 22 until it abuts against the flip box 21. Then, the second motor 31 drives the locking plate 30 to rotate via the rotating shaft 29, and the locking plate 30 locks and fixes the flipping rod 23, causing the photovoltaic panel 40 to drop in height. The linkage mechanism in the unfolded state supports the installation mechanism and the photovoltaic panel 40, ensuring maximum wind resistance. At the same time, the tilted photovoltaic panel 40 facilitates rainwater drainage and improves waterproof performance.
