[0034] The folding mechanism comprises: a support body 1, a movable part 10 slidably connected to the support body 1, a first rod 3 rotatably connected to the movable part 10, and a second rod 4 having two ends rotatably connected to the first rod 3 and the support body 1.

[0035] The frame body 5 is used to fix the photovoltaic module to be installed, and its two sides are rotatably connected to the end of the support body 1 and the first rod 3, respectively.

[0036] The locking part is used for locking or unlocking between the support body 1 and the movable part 10, and is arranged on the movable part 10.

[0037] The one-piece foldable photovoltaic support system of the utility model is rotatably connected to the support body 1 and the first rod 3 through the frame body 5, and is movably connected to the support body 1 in cooperation with the first rod 3, and can rotate and slide relative to the support body 1 at the same time, so that the frame body 5 can be rotatably connected to the support body 1 on one side, and the other side can be supported by corresponding rotation angles through the first rod 3 and the second rod 4, forming a movable triangular structure. When the first rod 3 and the second rod 4 are rotated to be approximately parallel to the support body 1, the system support is in a folded state. When the first rod 3 is rotated upward with the rotating part and the second rod 4 as the fulcrum, and the rotating part moves away from the connection between the frame body 5 and the support body 1, the second rod 4 is rotated by the support body 1 as the fulcrum by a corresponding angle, the system support is gradually unfolded, and the support body 1 and the rotating part are locked by the locking part, so as to lock the rotation angle of the frame body 5.

[0038] The locking component is a threaded locking component. In use, the user only needs to loosen the fastening screw of the slide groove 11 to unfold the bracket to a certain angle, and then tighten the fastening screw of the slide groove 11 again to lock the angle. The locking component is clamped on both sides of the support body 1. The screw passes through the locking component body and the support body 1. By tightening the screw, the locking component body on both sides is pressed against the support body 1 to keep locked.

[0039] Reference Figure 1 , Figure 5 As shown, the frame 5 is also equipped with an inverter 6, whose input end is connected to the output end of the photovoltaic module to be fixed. The inverter 6 is located on the frame 5. The vertical projection areas of the frame 5 and the inverter 6 do not overlap. The input end of the inverter 6 is connected to the output end of the photovoltaic module to be fixed to realize the conversion and output of electrical energy. Furthermore, the vertical projection areas of the frame 5 and the inverter 6 do not overlap to avoid the inverter 6 from obstructing or interfering with the folding of the frame 5. In this embodiment, the projection area of ​​the frame 5 is larger than that of the support body 1, and the inverter 6 is located outside the area enclosed by the support body 1.

[0040] Reference Figure 3 As shown, there is an angle between the axes of the first rod 3 and the second rod 4, and the tilt directions of the first rod 3 and the second rod 4 are opposite. The angle between the plane where the frame 5 is located and the axis where the support body 1 is located is 0°–60°, so that the first rod 3 and the second rod 4 form a triangular support. In this embodiment, the folding and unfolding angle range of the frame 5 is 0°–35°.

[0041] Reference Figure 1 , Figure 2 As shown, the movable component 10 includes: a movable pivot 101 slidably connected to the support body 1 along the length direction of the support body 1, and a rotating seat 102 rotatably connected to the movable pivot 101. The rotating component is slidably connected to the support body 1 through the movable pivot 101, providing displacement for the folding and unfolding of the system. The first rod 3 is rotatably and slidably connected to the support body 1 through the cooperation of the rotating seat 102 and the movable pivot 101.

[0042] The number of folding mechanisms is at least two sets, and the at least two sets of folding mechanisms are arranged at intervals, which further increases the stability of the folding mechanisms.

[0043] Reference Figure 1 As shown, at least one or more third rods 7 are provided between at least two sets of folding mechanisms. The third rods 7 and the support body 1 form a bearing frame 5. The position of the third rods 7 can be adjusted by the slide groove 11 and fixed to the support body 1. The bearing frame 5 is used to place counterweights. One or more third rods 7 form a bearing frame 5 between two sets of folding mechanisms. By placing heavy objects such as sandbags or bricks on the bearing frame 5, the stability is increased and it is prevented from being blown away by the wind.

[0044] With reference to the accompanying drawings Figure 1 As shown in the drawings, the frame body 5 is respectively provided with a first rotating member 8 and a second rotating member 9, the end of the first rod 3 is rotatably connected to the frame body 5 through the first rotating member 8, and the end of the support body 1 is rotatably connected to the frame body 5 through the second rotating member 9. The rotating connection structure of the first rotating member 8, the second rotating member 9 and the movable member 10 provides cushioning and support, so that the frame body 5, the first rod 3 and the support body 1 can be folded in parallel.

[0045] With reference to the accompanying drawings Figure 2 As shown in the drawings, the first side of the support body 1 is provided with a sliding groove 11 along the length direction, the rotating shaft of the movable member 10 is arranged to pass through and slideably connected to the sliding groove 11, and the second side of the support body 1 is provided with one or more positioning holes 12 spaced apart from the first rod 3.

The rotating assembly includes a rotating assembly body and a positioning rotating shaft. The second rod 4 is provided with the positioning rotating shaft arranged to pass through the positioning hole 12. The sliding groove 11 is arranged in the middle of the first support body 1. The positioning hole 12 is arranged to fix the position of the second rod 4 on the support body 1. A plurality of positioning holes 12, such as three or five, are arranged to position and rotate the lower end of the frame body 5 at different positions. The folding system can be adjusted in the upper limit of the angle according to the weight of the photovoltaic module, the wind environment and the installation environment, thereby improving the stability of the folding support system. In some embodiments, the rotating assembly and the movable member 10 are similar in structure, and the positioning rotating shaft thereof is slideably connected to the sliding groove 11 and is provided with a locking member, so that the position and the center of gravity of the frame body 5 on the support body 1 can be freely adjusted. After the position of the frame body 5 is arranged, the positions of the two ends of the second rod 4 on the first rod 3 and the support body 1 remain unchanged, and the two ends only provide rotating support points. The rotating assembly and the sliding groove 11 can also adopt damping sliding, and the damping is greater than the activity resistance of the second rod 4 under the gravity of the frame body 5. The folding system can be quickly adjusted without tools. When the frame body 5 faces the wind surface (the side of the photovoltaic panel), the folding system can be automatically folded when the wind is strong, thereby protecting the frame body 5 itself and the surrounding personnel. When the frame body 5 faces away from the wind surface, the length of the second rod 4 is greater than the length from the connection between the second rod 4 and the first rod 3 to the movable member 10, so that the panel of the frame body 5 and the folding mechanism are parallel and attached to the wall surface, thereby minimizing the wind resistance to avoid being blown off.

[0046] With reference to the accompanying drawings Figure 1 , Figure 2 As shown in the drawings, the support body 1 is provided with an angle scale 2, and the angle scale 2 is arranged on the movement path of the first rotating member 8 and is used to identify the angle of the frame body 5. The angle scale 2 arranged on the support body 1 can provide accurate and intuitive reference for users when adjusting the angle of the frame body 5, thereby facilitating the installation personnel to adjust the frame body 5 to the desired angle to obtain the best photovoltaic power generation effect.
