Description

Technical Field

[0001] This utility model relates to the field of solar energy support technology, and in particular to a foldable solar energy support. Background Technology

[0002] Solar panels, also known as photovoltaic panels, are devices that use the photoelectric effect of semiconductor materials to directly convert solar radiation energy into electrical energy. Their main material is silicon. By absorbing sunlight, they generate direct current and store it in batteries or directly power electrical appliances. Solar panels have advantages such as being clean, renewable, and pollution-free, and are an important part of the current renewable energy field. Small and medium-sized solar systems are often used for temporary power supply, outdoor operations, and emergency power supply. These scenarios have high requirements for the portability, ease of installation, and spatial adaptability of the equipment.

[0003] In the existing technology, traditional brackets are large in size and occupy a lot of space, which not only increases transportation costs but also makes warehousing management difficult. Furthermore, the use of bolts to fix solar panels requires additional equipment to remove the bolts in outdoor environments, which limits the applicability of the brackets. Therefore, a foldable solar bracket is proposed to solve the above-mentioned problems. Utility Model Content

[0004] To address the technical problems of existing technologies, such as the large size and space-consuming nature of traditional brackets, and the need for additional equipment to remove the bolts when fixing solar panels outdoors, this application provides a foldable solar bracket.

[0005] This utility model proposes a foldable solar panel bracket, which includes a support frame consisting of two frames hinged together by door hinges. The outer side of the support frame is provided with a folding mechanism, which includes a fixing block and a support rod. The lifting and lowering of the fixing block fixes the support rod.

[0006] The outer side of the support frame is provided with a fixing mechanism, which includes a fixing plate. The movement of the fixing plate fixes the solar panel.

[0007] Preferably, the folding mechanism further includes a support rod, which is rotatably connected to the outer surface of the round rod of the support rod. One end of the support rod and one end of the support rod are rotatably connected to the outer side of the support frame by a pin.

[0008] Through the above technical solution, the support rod and the support rod are rotatably connected, fixing them without affecting their rotation. The arc-shaped groove on the support rod is a half-circle, limiting the rotation angle of both to only 180 degrees, ensuring that the support frame is at the optimal angle when unfolded. Both the support rod and the support rod are rotatably connected to the support frame through pins, fixing them without affecting their deflection, thus forming a stable triangular support structure. The support frame achieves a folding function through door hinges, facilitating storage and transportation. The support rod, the support rod, and the support frame are all made of aluminum alloy, which is lightweight, corrosion-resistant, and suitable for outdoor environments.

[0009] Preferably, the curved surface of the support rod is threaded with a folded star head bolt, the lower surface of the bottom end of the folded star head bolt is rotatably connected to the upper surface of the fixing block, the fixing block is slidably inserted into the inner wall of the groove of the support rod, and the curved surface of the bottom end of the fixing block is in contact with the curved surface of the round rod of the support rod.

[0010] The above technical solution uses a support rod connected to a folded star-head bolt to fix it without affecting its rotation and lifting. The folded star-head bolt is rotatably connected to a fixing block, allowing it to rise and fall without affecting the fixing block. The fixing block is slidably inserted into the support rod to limit its movement and ensure stability during lifting. When it is necessary to fix the rotatably connected support rod, the folded star-head bolt is rotated, causing the fixing block to descend until its lower surface contacts the curved surface of the support rod, thus fixing it and preventing movement or rotation. Rotation in the opposite direction releases the fixation. The folded star-head bolt can be made of stainless steel, which has high strength and can withstand the torque during rotation. The fixing block is also made of aluminum alloy, and rubber pads can be added to the contact surface between the fixing block and the round rod of the support rod as needed to enhance friction.

[0011] Preferably, the fixing mechanism further includes a rubber pad, which is fixedly bonded to the lower surface of the fixing plate, and the fixing plate is slidably connected to the inner wall of the groove of the support frame.

[0012] The above technical solution uses a rubber pad to fix and bond the solar panel to the mounting plate, which is convenient for disassembly while securing it. The rubber pad is placed between the mounting plate and the solar panel and has good friction to prevent the solar panel from shifting under wind load or vibration. It also prevents the aluminum alloy mounting plate from directly contacting the surface of the solar panel, thus preventing scratches or wear. The mounting plate is slidably connected to the support frame, which does not affect the movement of the mounting plate while fixing it. It can accommodate solar panels of different thicknesses. At the same time, the installation and removal of the solar panel can be achieved by moving the mounting plate. The mounting plate is made of aluminum alloy, which reduces the overall weight while ensuring strength.

[0013] Preferably, the outer side of the support frame is threaded with a fixing star head bolt, and one end of the fixing star head bolt is rotatably connected to the outer side of the fixing plate.

[0014] The above technical solution uses a support frame and a fixed star head bolt threaded connection to fix the support frame without affecting its rotation and lifting. The fixed star head bolt is rotatably connected to the fixed plate. By rotating the fixed star head bolt, the fixed plate can be moved without additional tools. The fixed star head bolt is made of stainless steel to ensure that it is not easy to rust or wear during long-term use.

[0015] Preferably, elastic washers are placed on the outer surface of the top end of the fixed star head bolt and the outer surface of the top end of the folding star head bolt.

[0016] The above technical solution involves placing elastic washers on both the fixed star head bolts and the folding star head bolts to provide elastic preload and prevent loosening. The elastic washers can be made of silicone rubber, which has excellent UV resistance, ozone resistance, and corrosion resistance, making it suitable for long-term exposure to outdoor environments.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. By setting a folding mechanism, the support rod is fixed. Both the support rod and the support frame are rotatably connected to the support frame through pins, thus forming a stable triangular support structure. The support frame achieves the folding function through door hinges, which facilitates storage and transportation. When it is necessary to fix the rotatably connected support rod, rotate the folding star head bolt, which drives the fixing block to descend until its lower surface contacts the arc surface of the support rod, thereby fixing it and preventing movement and rotation. Rotating in the opposite direction will release the fixation. This solves the technical problem in the existing technology that traditional brackets are large in size, occupy a lot of space, and not only increase transportation costs but also make warehouse management difficult.

[0019] 2. By setting up a fixing mechanism, the solar panel is fixed. A rubber pad is placed between the fixing plate and the solar panel to prevent the solar panel from shifting under wind load or vibration, and to avoid the aluminum alloy fixing plate directly contacting the surface of the solar panel, preventing scratches or wear. The fixing plate can be moved by rotating the fixing star head bolts without additional tools. Both the fixing star head bolts and the folding star head bolts are equipped with elastic washers to provide elastic pre-tightening force and prevent loosening. This solves the technical problem in the existing technology where the solar panel is fixed with bolts, which requires additional equipment to remove the bolts in outdoor environments, thus limiting the applicability of the bracket.

[0027] 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.

[0028] Reference Figures 1-6 A foldable solar panel bracket includes a support frame 1, which consists of two frames hinged together by door hinges. The outer side of the support frame 1 is provided with a folding mechanism, which includes a fixing block 31 and a support rod 21. The lifting and lowering of the fixing block 31 fixes the support rod 21.

[0029] To ensure that the support frame 1 is at the optimal angle when unfolded, the folding mechanism also includes a support rod 2. The support rod 2 is rotatably connected to the outer surface of the round rod of the support rod 21. One end of the support rod 2 and one end of the support rod 21 are rotatably connected to the outer side of the support frame 1 through a pin. The rotatable connection between the support rod 2 and the support rod 21 fixes them without affecting their rotation. The arc-shaped groove on the support rod 2 is a half-circle, which limits the rotation angle of the two, so that they only rotate 180 degrees, ensuring that the support frame 1 is at the optimal angle when unfolded. The support rod 2 and the support rod 21 are rotatably connected to the support frame 1 through a pin, which fixes them without affecting their deflection, thus forming a stable triangular support structure. The support frame 1 achieves the folding function through a door hinge, which is convenient for storage and transportation. The support rod 2, the support rod 21, and the support frame 1 are all made of aluminum alloy, which is lightweight, corrosion-resistant, and suitable for outdoor environments.

[0030] To lower the fixed block 31, a folded star-head bolt 3 is threaded onto the curved surface of the support rod 2. The lower surface of the bottom end of the folded star-head bolt 3 is rotatably connected to the upper surface of the fixed block 31. The fixed block 31 is slidably inserted into the inner wall of the groove of the support rod 2. The curved surface of the bottom end of the fixed block 31 contacts the curved surface of the round rod of the support rod 21. The support rod 2 is bolted to the folded star-head bolt 3, which fixes the fixed block without affecting its rotation and lifting. The folded star-head bolt 3 is rotatably connected to the fixed block 31, which lifts the fixed block without affecting its rotation and lifting. 31 is slidably inserted into the support rod 2 to limit its movement and ensure its stability during lifting. When it is necessary to fix the support rod 21 rotatably connected to the support rod 2, rotate the folding star head bolt 3 to drive the fixing block 31 down until its lower surface contacts the arc surface of the round rod of the support rod 21, thereby fixing it and preventing movement and rotation. Rotating in the opposite direction will release the fixation. The folding star head bolt 3 can be made of stainless steel, which has high strength and can withstand the torque during rotation. The fixing block 31 is also made of aluminum alloy. Four rubber pads can be added to the contact surface between the fixing block 31 and the round rod of the support rod 21 as needed to enhance the friction.

[0031] By setting a folding mechanism, the support rod 21 is fixed. Both the support rod 2 and the support rod 21 are rotatably connected to the support frame 1 through pins, thus forming a stable triangular support structure. The support frame 1 achieves the folding function through door hinges, which facilitates storage and transportation. When it is necessary to fix the support rod 21 rotatably connected to the support rod 2, the folding star head bolt 3 is rotated, which drives the fixing block 31 to descend until its lower surface contacts the arc surface of the round rod of the support rod 21, thereby fixing it and preventing movement and rotation. Rotating in the opposite direction will release the fixation. This solves the technical problem in the existing technology that traditional brackets are large in size, occupy a lot of space, and not only increase transportation costs but also make warehouse management difficult.

[0032] In order to fix the solar panel, a fixing mechanism is provided on the outer side of the support frame 1. The fixing mechanism includes a fixing plate 41, and the movement of the fixing plate 41 fixes the solar panel.

[0033] To facilitate the installation and removal of the solar panel, the fixing mechanism also includes a rubber pad 4, which is fixedly bonded to the lower surface of the fixing plate 41. The fixing plate 41 is slidably connected to the inner wall of the groove of the support frame 1. The rubber pad 4 is fixedly bonded to the fixing plate 41, which facilitates removal while fixing it. The rubber pad 4 is placed between the fixing plate 41 and the solar panel. The rubber pad 4 has good friction to prevent the solar panel from shifting under wind load or vibration, and to prevent the aluminum alloy fixing plate 41 from directly contacting the surface of the solar panel, thus preventing scratches or wear. The fixing plate 41 is slidably connected to the support frame 1, which fixes it without affecting the movement of the fixing plate 41. It can accommodate solar panels of different thicknesses. At the same time, the installation and removal of the solar panel are achieved by moving the fixing plate 41. The fixing plate 41 is made of aluminum alloy, which reduces the overall weight while ensuring strength.

[0034] To drive the fixed plate 41 to move, a fixed star head bolt 5 is threadedly connected to the outer side of the support frame 1. One end of the fixed star head bolt 5 is rotatably connected to the outer side of the fixed plate 41. The support frame 1 is threadedly connected to the fixed star head bolt 5, which fixes the plate 41 without affecting its rotation and lifting. The fixed plate 41 is rotatably connected to the fixed star head bolt 5. By rotating the fixed star head bolt 5, the fixed plate 41 can be driven to move without additional tools. The fixed star head bolt 5 is made of stainless steel to ensure that it is not easy to rust or wear during long-term use.

[0035] To prevent the fixed star head bolt 5 and the folded star head bolt 3 from loosening, elastic washers 6 are placed on the outer surface of the top end of the fixed star head bolt 5 and the outer surface of the top end of the folded star head bolt 3. The elastic washers 6 on both the fixed star head bolt 5 and the folded star head bolt 3 provide elastic preload to prevent loosening. The elastic washers 6 can be made of silicone rubber, which has excellent UV resistance, ozone resistance and corrosion resistance, and is suitable for long-term exposure to outdoor environments.

[0036] By setting up a fixing mechanism, the solar panel is fixed. The rubber pad 4 is placed between the fixing plate 41 and the solar panel to prevent the solar panel from shifting under wind load or vibration, and to prevent the aluminum alloy fixing plate 41 from directly contacting the surface of the solar panel, thus preventing scratches or wear. The fixing plate 41 can be moved by rotating the fixing star head bolt 5 without the need for additional tools. Both the fixing star head bolt 5 and the folding star head bolt 3 are equipped with elastic washers 6 to provide elastic preload and prevent loosening. This solves the technical problem in the prior art where fixing the solar panel with bolts requires additional equipment to remove the bolts in outdoor environments, which limits the applicability of the bracket.

[0037] Working principle: When using the folding solar bracket, the folding support frame 1 is slowly unfolded through the door hinge. At this time, the two frames begin to deflect from the folded state to the unfolded state. During the unfolding process, the support rod 2 and the support rod 21, which are rotatably connected to the support frame 1 through the pin, also deflect and unfold. The door hinge connection is equipped with a limit pin, which is existing technology and will not be explained in detail here. When the support frame 1 is unfolded to the point where the two frames are perpendicular to each other, that is, at a 45-degree angle with the ground, the limit pin automatically stops further unfolding, ensuring that the angle is accurate and stable. At the same time, the support rod 2 and the support rod 21 are parallel to the ground, thus forming a stable triangular support structure with the support frame 1.

[0038] When it is necessary to fix the support rod 21, the user rotates the folded star head bolt 3 on the support rod 2, which drives the fixing block 31 connected to it to descend along the groove of the support rod 2. When the fixing block 31 descends to the point where its bottom arc surface is in close contact with the arc surface of the round rod of the support rod 21, the rotation of the folded star head bolt 3 is stopped. At this time, the support rod 21 is pressed by the fixing block 31 and cannot be rotated or moved. The triangular support structure is completely locked, ensuring that the support frame 1 does not shake or shift angle under load. If it is necessary to fold the support frame 1, the folded star head bolt 3 is rotated in the opposite direction, which drives the fixing block 31 to rise and disengage it from the support rod 21. The support rod 21 can then rotate freely again for easy storage.

[0039] Place the solar panel in the predetermined installation position of the support frame 1, ensuring that its edge is below the fixing plate 41 of the fixing mechanism. Rotate the fixing star head bolt 5 on the outside of the support frame 1, causing the fixing plate 41, which is rotatably connected to it, to slide along the groove of the support frame 1. When the rubber pad 4 on the lower surface of the fixing plate 41 is in close contact with the surface of the solar panel, stop rotating the fixing star head bolt 5.

[0040] Silicone rubber elastic washers 6 are placed on the outer surface of the top of the shank of both the fixed star head bolt 5 and the folded star head bolt 3 to provide continuous elastic preload, prevent the bolts from loosening due to vibration or external force, and ensure long-term stability.

[0041] Inspect the key components of the bracket every 3-6 months, including door hinges, pins, star-head bolts, fixing blocks 31 and fixing plates 41, to check for looseness, wear or corrosion. If the rubber pads 4 or elastic washers 6 are found to be aged or cracked, they should be replaced in time. If the sliding parts of the fixing blocks 31 or fixing plates 41 are severely worn, affecting stability, the corresponding parts should be replaced. If the star-head bolts are found to be loose, they should be retightened and the elastic washers 6 should be checked for failure.

[0042] Lubrication is recommended every 6 months for the door hinges, pins, rotating connections between support rod 2 and support rod 21, and sliding contact surfaces between fixing block 31 and support rod 2. If the bracket is used in a dusty or humid environment, this period can be shortened to 3 months. Silicone-based grease or PTFE lubricant is recommended, as it has good waterproof properties, resistance to high and low temperatures, and long-lasting lubrication effect. Before lubrication, clean the dust and sand particles from the lubrication area with a dry cloth, then apply a small amount of lubricant evenly to avoid excessive application that may attract dust. After lubrication, operate the folding mechanism several times to allow the lubricant to fully penetrate, and finally wipe away any excess lubricant to keep the surface clean.

[0043] 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.
