[0047] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the scope of protection of this invention. The singular forms “a,” “the,” or “the” used in the specification and claims of this invention are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0048] Please refer to Figures 1 to 11 This utility model discloses a manually folding photovoltaic bracket 10, which includes at least two photovoltaic brackets 100 and a first hinge device 1. Each photovoltaic bracket 100 includes two columns 2, a bearing assembly 3 mounted on the top of the column 2, a connecting rod 4 rotatably arranged around an axis on the top of the two columns 2, and an angle fixing mechanism 5. The connecting rod 4 is used to install photovoltaic units 30. Two opposing columns 2 of two adjacent photovoltaic brackets 100 are hinged by the first hinge device 1, so that the two adjacent photovoltaic brackets 100 can be unfolded or folded. The folding process is simple and quick, and occupies little space.

[0049] For ease of explanation, this utility model defines the following: Figure 1 The length direction of at least two photovoltaic brackets 100 after unfolding is the first direction D1-D1, the width direction of the photovoltaic brackets 100 is the second direction D2-D2, and the height direction of the photovoltaic brackets 100 is the third direction D3-D3. The first direction D1-D1, the second direction D2-D2, and the third direction D3-D3 are perpendicular to each other.

[0050] Please refer to Figures 1 to 4 as well as Figure 11 The first hinge device 1 connects two adjacent columns 2 of two adjacent photovoltaic brackets 100 to allow the two adjacent photovoltaic brackets 100 to be unfolded or folded. Specifically, when the folded photovoltaic bracket 100 is in the unfolded state, two adjacent photovoltaic brackets 100 in the first direction D1-D1 are connected by the first hinge device 1, which is hinged to two adjacent columns 2 of the two photovoltaic brackets 100 along the first direction D1-D1. In one embodiment, the column 2 includes two legs 21 spaced apart along the second direction D2-D2, a top seat 22 connected to the top of the two legs 21, and a base 23 connected to the bottom of the two legs 21. The first hinge device 1 is hinged to the legs 21 on the same side of the two columns 2 in the second direction D2-D2. When the manually folded photovoltaic bracket 10 is in the folded state, the columns 2 of any two adjacent photovoltaic brackets 100 are arranged in a row along the second direction D2-D2, and multiple legs 21 are spaced apart along the second direction D2-D2. In another embodiment, the column 2 can also be a single support leg 21.

[0051] Please refer to Figure 1 as well as Figure 2The first hinge device 1 is a hinge, chain, or other existing connector capable of connecting two components and allowing them to rotate. The rotation axis of the first hinge device 1 is parallel to or along a third direction D3-D3 with the column 2, and the two photovoltaic brackets 100 rotate around the rotation axis via the first hinge device 1. In this embodiment, the first hinge device 1 is a hinge, which is rotated manually so that one of the columns 2 can rotate 180° counterclockwise or clockwise around the other column 2, enabling the unfolding and folding of multiple photovoltaic brackets 100.

[0052] Please refer to Figure 5 To facilitate quick and easy fixing of the manually foldable photovoltaic bracket 10 after folding or unfolding, the manually foldable photovoltaic bracket 10 also includes a fixing component 200 fixed to the bottom of each column 2. The fixing component 200 includes a fixing plate 210 and a first fastener 220. The fixing plate 210 is connected to the column 2 and fixed to the ground by the first fastener 220. When the manually foldable photovoltaic bracket 10 is folded or unfolded, it is fixed to the ground by the fixing component 200.

[0053] Please refer to Figures 5 to 7 The bearing assembly 3 is located at the top of the column 2, and the connecting rod 4 is located inside the bearing assembly 3. The bearing assembly 3 drives the connecting rod 4 to rotate around its axis. Specifically, the bearing assembly 3 includes a bearing seat 31 and a bearing 32 located inside the bearing seat 31. The bearing seat 31 is located at the top of the column 2, and the connecting rod 4 is located inside the bearing 32. The bearing assembly 3 drives the connecting rod 4 to rotate around its axis. The bearing seat 31 includes a hollow rotating part 311 and two fixing parts 312 located on opposite sides of the rotating part 311. The bearing 32 is located inside the rotating part 311, and the fixing parts 312 are fixed to the top seat 22 of the column 2 by bolts.

[0054] Please refer to Figures 3 to 8 as well as Figure 10The angle fixing mechanism 5 includes a support plate 51 and a positioning pin 52. The positioning pin 52 is installed on the support plate 51, which is located on the column 2 and below the connecting rod 4. The connecting rod 4 has a first groove structure 41 and a second groove structure 42 in the radial direction. The first groove structure 41 and the second groove structure 42 are located on the same cross section of the connecting rod 4. The included angle formed by the axes of the first groove structure 41 and the second groove structure 42 is between 60 and 120 degrees. Preferably, the included angle formed by the axes of the first groove structure 41 and the second groove structure 42 is 90 degrees. When the manually folded photovoltaic bracket 10 is in the designated position in the unfolded state, the positioning pin 52 is inserted into the first groove structure 41 to fix the angle of the connecting rod 4, so that the connecting rod 4 is in the first position and the angle of the photovoltaic unit 30 fixed on the connecting rod 4 remains horizontal. When the manually foldable photovoltaic bracket 10 needs to be folded, first pull out the positioning pin 52, rotate the connecting rod 4 or the photovoltaic unit 30 installed on the connecting rod 4, and after the positioning pin 52 corresponds to the designated position of the second groove structure 42, the positioning pin 52 is inserted into the second groove structure 42, so that the connecting rod 4 is in the second position and the photovoltaic unit 30 fixed on the connecting rod 4 is perpendicular to the ground. Then, rotate the photovoltaic bracket 100 through the first hinge device 1 so that the folding bracket is in the folded state.

[0055] The support plate 51 has an "L" shaped structure. The support plate 51 includes a first support part 511 and a second support part 512 vertically disposed on the first support part 511. The first support part 511 is fixedly connected to the top of the column 2, and the second support part 512 extends toward the other column 2.

[0056] In this embodiment, a single photovoltaic bracket 100 has two sets of angle fixing mechanisms 5, which are located on opposite sides of the two sets of bearing assemblies 3. In other embodiments, the angle fixing mechanisms 5 on a single photovoltaic bracket 100 may be one set or more than three sets.

[0057] Please refer to Figure 5 as well as Figure 7The foldable photovoltaic module includes three photovoltaic supports: a first photovoltaic support 1001, a second photovoltaic support 1002, and a third photovoltaic support 1003. In the unfolded state, the first photovoltaic support 1001, the second photovoltaic support 1002, and the third photovoltaic support 1003 are arranged sequentially along a first direction D1-D1, with the second photovoltaic support 1002 located between the first photovoltaic support 1001 and the third photovoltaic support 1003. The first photovoltaic support 1001 and the third photovoltaic support 1003 are located on opposite sides of the second photovoltaic support 1002 along its length. The first photovoltaic support 1001 rotates clockwise via the first hinge device 1 to be placed side-by-side with the second photovoltaic support 1002 along its width, and the third photovoltaic support 1003 rotates counterclockwise via the first hinge device 1 to be placed side-by-side with the second photovoltaic support 1002 along its width.

[0058] The first photovoltaic support 1001 includes a first column 201 and a second column 202 spaced apart, and a first connecting rod 401 rotatably disposed on the top of the first column 201 and the second column 202. The second photovoltaic support 1002 includes a third column 203 and a fourth column 204 spaced apart, and a second connecting rod 402 rotatably disposed on the top of the third column 203 and the fourth column 204. The third photovoltaic support 1003 includes a fifth column 205 and a sixth column 206 spaced apart, and a third connecting rod 403 rotatably disposed on the top of the fifth column 205 and the sixth column 206. The first hinge device 1 includes a first sub-hinged device 101 and a second sub-hinged device 102. The second column 202 and the third column 203 are adjacent and close to each other and are connected by the first sub-hinged device 101. The fourth column 204 and the fifth column 205 are adjacent and close to each other and are connected by the second sub-hinged device 102. The first sub-hinged device 101 and the second sub-hinged device 102 are respectively located on opposite sides of their respective columns 2 in the second direction D2-D2, so that the first photovoltaic bracket 1001 rotates counterclockwise (or clockwise) and is located on one side of the second photovoltaic bracket 1002 in the second direction D2-D2, and the third photovoltaic bracket 1003 rotates in the same direction and is located on the other side of the second photovoltaic bracket 1002 in the second direction D2-D2. The first column 201, second column 202, third column 203, fourth column 204, fifth column 205, and sixth column 206 all have the same structure, as do the first connecting rod 401, second connecting rod 402, and third connecting rod 403. When the first photovoltaic support 1001, second photovoltaic support 1002, and third photovoltaic support 1003 are in the deployed state, the first column 201, second column 202, third column 203, fourth column 204, fifth column 205, and sixth column 206 are arranged in a straight line along the first direction D1-D1.

[0059] Preferably, the bottom of the third column 203 and the fourth column 204 are respectively provided with a first limiting member 6 and a second limiting member 7. The first limiting member 6 and the second limiting member 7 are limiting rods extending along the second direction D2-D2, and are installed on the ground by the locking assembly 8. When the photovoltaic bracket 10 is manually folded from the unfolded state to the folded state, the first photovoltaic bracket 1001 is driven to rotate so that the first column 201 abuts against the first limiting member 6, realizing that the first photovoltaic bracket 1001 completes a 180-degree rotation angle; the third photovoltaic bracket 1003 is driven to rotate so that the sixth column 206 abuts against the second limiting member 7, realizing that the second photovoltaic bracket 1002 completes a 180-degree rotation angle.

[0060] In summary, when the first photovoltaic support 1001, the second photovoltaic support 1002, and the third photovoltaic support 1003 move from the unfolded state to the folded state, the first photovoltaic support 1001 is manually rotated 180° counterclockwise (or clockwise) around the first hinge device 1, so that the first column 201 and the fourth column 204 of the first photovoltaic support 1001 are side by side. Then, the third photovoltaic support 1003 is rotated 180° in the same direction around another first hinge device 1, so that the sixth column 206 of the third photovoltaic support 1003 is in contact with the third column 203. This completes the folding of the first photovoltaic support 1001, the second photovoltaic support 1002, and the third photovoltaic support 1003. The folding process is convenient and quick, and occupies little space. The unfolding or folding method for more than three odd-numbered photovoltaic supports can be carried out in the same way as the above three sets, and will not be elaborated here.

[0061] Please refer to Figure 1 , Figure 4 as well as Figures 8 to 9 This utility model also discloses a photovoltaic system 20, which includes a manually folding photovoltaic bracket 10, photovoltaic units 30, a second hinge device 40 disposed on the brackets of two adjacent photovoltaic units 30, and a connecting component 50. Multiple sets of photovoltaic units 30 are arranged in the same row along a second direction D2-D2. Each photovoltaic unit 30 includes a rectangular hollow frame 310 and a photovoltaic module 320 disposed within the hollow frame 310. The frame of the photovoltaic module 320 is locked to the frame 310 by a second fastener 520. The second hinge device 40 is installed between the two frames 310 of two adjacent photovoltaic units 30, allowing one of the two adjacent photovoltaic units 30 to rotate and overlap onto the other for folding. In this embodiment, three groups of photovoltaic units 30 are arranged in the same row along the second direction D2-D2, namely, a second photovoltaic unit 302, a first photovoltaic unit 301, and a third photovoltaic unit 303. One of the aforementioned second hinge devices 40 is provided between the first photovoltaic unit 301 and the second photovoltaic unit 302, and another second hinge device 40 is provided between the second photovoltaic unit 302 and the third photovoltaic unit 303, so that the second photovoltaic unit 302 can rotate to one side of the first photovoltaic unit 301, and the third photovoltaic unit 303 can rotate to the other side of the first photovoltaic unit 301. The second hinge device 40 is a hinge or a latch.

[0062] Please refer to Figure 2The connecting component 50 includes a connecting plate 510 and a second fastener 520. When the three photovoltaic units 30 are unfolded, adjacent first photovoltaic units 301 and second photovoltaic units 302 are connected as one unit through the connecting plate 510 and the second fastener 520. The first photovoltaic unit 301 and the third photovoltaic unit 303 are also connected as one unit through the connecting plate 510 and the second fastener 520, so that the three sets of photovoltaic units 30 are fixedly connected to each other, forming a single plane. In other embodiments, the number of photovoltaic units 30 is not limited and can be an odd number of three or more sets. The second fastener 520 is a bolt or other existing fastening component.

[0063] Please refer to Figure 8 After the three or more photovoltaic units 30 are deployed, the first photovoltaic unit 301 is located at the middle position in the second direction D2-D2. The first photovoltaic unit 301 is fixedly connected to the connecting rod 4 so that the three photovoltaic units 30 can rotate with the rotation of the connecting rod 4. In this embodiment, the frame of the first photovoltaic unit 301 is welded and fixed to the connecting rod 4.

[0064] The frame of the first photovoltaic unit 301 includes a first side 3001, a second side 3002, a third side 3003, and a fourth side 3004 connected in a clockwise direction. The frame of the second photovoltaic unit 302 includes a fifth side 3005, a sixth side 3006, a seventh side 3007, and an eighth side 3008 connected in a clockwise direction. The frame of the third photovoltaic unit 303 includes a ninth side 3009, a tenth side 3010, an eleventh side 3011, and a twelfth side 3012 connected in a clockwise direction. At least two second hinge devices 40 are provided between the third side 3003 and the fifth side 3005, allowing the second photovoltaic unit 302 to rotate around the third side 3003. At least two second hinge devices 40 are provided between the first side 3001 and the eleventh side 3011, allowing the third photovoltaic unit 303 to rotate around the first side 3001.

[0065] When the first photovoltaic unit 301, the second photovoltaic unit 302, and the third photovoltaic unit 303 are in the unfolded state, they are connected by the second hinge device 40 and arranged in a straight line along the second direction D2-D2. Connecting plates 510 are provided at the opposite ends of the fourth side 3004 and the eighth side 3008, the opposite ends of the fourth side 3004 and the twelfth side 3012, the opposite ends of the second side 3002 and the sixth side 3006, and the opposite ends of the second side 3002 and the tenth side 3010, so that the first photovoltaic unit 301, the second photovoltaic unit 302, and the third photovoltaic unit 303 remain stable in the unfolded state.

[0066] When the first photovoltaic unit 301, the second photovoltaic unit 302, and the third photovoltaic unit 303 move from the unfolded state to the folded state, the connecting plate 510 is first manually removed. The second photovoltaic unit 302 is then manually rotated upwards around the third side 3003 by 180°, so that the second photovoltaic unit 302 is in contact with the first photovoltaic unit 301. Then, the third photovoltaic unit 303 is manually rotated downwards around the first side 3001 by 180°, so that the third photovoltaic unit 303 is in contact with the first photovoltaic unit 301, thus completing the folding of the first photovoltaic unit 301, the second photovoltaic unit 302, and the third photovoltaic unit 303. Finally, the connecting rod 4 is rotated so that the folded first photovoltaic unit 301, the second photovoltaic unit 302, and the third photovoltaic unit 303 are perpendicular to the ground. The folding process is convenient, quick, and occupies little space.

[0067] In summary, this utility model discloses a manually folding photovoltaic bracket 10, which includes at least two photovoltaic brackets 100. Each photovoltaic bracket 100 includes two columns 2 and a connecting rod 4 rotatably disposed on the top of the two columns 2. Two opposing columns 2 of two adjacent photovoltaic brackets 100 are hinged by a first hinge device 1, so that the two adjacent photovoltaic brackets 100 can be unfolded or folded. The folding process is convenient and quick, and occupies little space. In addition, this utility model discloses a photovoltaic system 20, including the above-mentioned manually folding photovoltaic bracket 10 and multiple sets of photovoltaic units 30. The multiple sets of photovoltaic units 30 are hinged by a second hinge device 40, so that two adjacent photovoltaic units 30 can rotate around the axis of the second hinge device 40 for folding, which is quick, convenient, and low in cost.
