[0037] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that for the convenience of description, only the parts related to the present invention are shown in the drawings, rather than all of them.

[0038] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0039] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "over", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under", and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the horizontal height of the first feature is lower than that of the second feature.

[0040] As Figures 1 - 5 shown, the photovoltaic bracket of this embodiment includes a bracket base 1 and a connector 2. A first clamping portion 111 is provided on the bracket base 1, and a second clamping portion 21 and a third clamping portion 22 are provided on the connector 2. A fourth clamping portion 32 is provided on the bottom plate of the photovoltaic panel 800. The second clamping portion 21 cooperates with the first clamping portion 111 to enable the connector 2 to be clamped to the bracket base 1, and the third clamping portion 22 cooperates with the fourth clamping portion 32 to enable the connector 2 to be clamped to the photovoltaic panel 800. Since the connector 2 can be clamped to the bracket base 1, the assembly process of the photovoltaic bracket can be simplified. And since the connector 2 can be clamped to the photovoltaic panel 800, the assembly process of the photovoltaic panel 800 and the photovoltaic bracket can be simplified, making the assembly, disassembly, and maintenance more convenient and improving the work efficiency.

[0041] As Figures 1 - 2As shown, preferably, the connecting member 2 includes a first supporting surface 24 and a second supporting surface 23 that are both inclined and perpendicular to each other. The photovoltaic panel 800 includes a back surface and a first side surface that are perpendicular to each other. The first supporting surface 24 abuts against the back surface, and the second supporting surface 23 abuts against the first side surface.

[0042] Preferably, the first clamping portion 111 is a second groove extending along the width direction of the bracket base 1. The included angle between the groove depth direction of the second groove and the length direction of the bracket base 1 is an acute angle. The second clamping portion 21 is a convex structure that cooperates with the second groove, which can prevent the connecting member 2 from moving relative to the bracket base 1 along the length direction of the bracket base 1.

[0043] The third clamping portion 22 is a third groove. The maximum width of the third groove is greater than the width of the groove opening of the third groove. The third groove runs through along the width direction of the connecting member 2, and the fourth clamping portion 32 on the photovoltaic panel 800 is in interference fit with the third groove of the connecting member 2, which can prevent the photovoltaic panel 800 from detaching from the connecting member 2 and facilitate the insertion of the fourth clamping portion 32 into the third groove.

[0044] As Figure 2 shown, in order to prevent the connecting member 2 from detaching from the bracket base 1, preferably, the photovoltaic bracket further includes a pressing member 3. The pressing member 3 includes a pressing surface 31 and a fifth clamping portion 32. As Figure 1 shown, a first groove 112 is formed on the bracket base 1. The maximum width of the first groove 112 is greater than the width of the groove opening of the first groove 112. The fifth clamping portion 32 is arranged in the first groove 112 and is in interference fit with the first groove 112. And because the maximum width of the first groove 112 is greater than the width of the groove opening of the first groove 112, the interference fit of the fifth clamping portion 32 in the first groove 112 makes it difficult for the fifth clamping portion 32 to detach from the groove opening of the first groove 112. The pressing surface 31 of the pressing member 3 abuts against the connecting member 2, specifically against the abutting surface 25 of the connecting member 2, so that the connecting member 2 abuts against the bracket base 1, ensuring a reliable connection between the connecting member 2 and the bracket base 1.

[0045] Preferably, the cross-section of the first groove 112 is a circle with an upward vertical opening. The fifth clamping portion 32 includes two relatively spaced curved panels 321. The curved panels 321 are in interference fit with the side walls of the first groove 112. Since the two curved panels 321 are spaced apart, the distance between them has a certain variable, so that the fifth clamping portion 32 can be inserted into the first groove 112 and is in interference fit with the first groove 112. Of course, in other embodiments, the shape of the cross-section of the first groove 112 can also be set as a polygon, an ellipse, etc., as long as it is ensured that the maximum width of the first groove 112 is greater than the width of its groove opening. Optionally, both ends of the first groove 112 along the length direction of the bracket base 1 are through, which is convenient for the fifth clamping portion 32 of the pressing member 3 to be inserted into the first groove 112 along this direction.

[0046] Preferably, in order to prevent the fifth clamping portion 32 of the crimping member 3 from slipping out of the first groove 112, after the fifth clamping portion 32 is inserted into the first groove 112, a fastener may be inserted between the two curved panels 321, and the fastener is press-fitted between the two curved panels 321. Preferably, a cylindrical fixing structure with a retaining piece may also be inserted at the connection hole 113, so that the retaining piece restricts the fifth clamping portion 32 of the crimping member 3 from slipping out of the first groove 112.

[0047] As Figure 2 shown, in order to adapt to two inclined photovoltaic panels 800, preferably, two sets of first clamping portions 111 are arranged at intervals along the length direction of the support base 1, and each set of first clamping portions 111 includes at least two first clamping portions 111 along the width direction of the support base 1. Each first clamping portion 111 is adapted to a connecting member 2, that is, one support base 1 can cooperate with at least four connecting members 2. For example, by using three support bases 1, two sets of photovoltaic panels 800 can be supported along the width direction of the support base 1, and each set of photovoltaic panels 800 includes two inclined photovoltaic panels 800 that intersect and support each other. The support base 1 at the edge can be used to set a wind baffle or an assembly with the ground, etc.

[0048] Optionally, the first groove 112 is provided in the middle of the support base 1, and the two connecting members 2 are respectively provided on both sides of the first groove 112. The fifth clamping portion 32 is provided in the middle of the crimping member 3, and the crimping surface 31 of one crimping member 3 can simultaneously abut against the abutting surfaces 25 of the two connecting members 2.

[0049] In order to save materials and reduce costs, preferably, the support base 1 includes two base piers 11 and a connecting rod 12. A plurality of connection holes 113 are horizontally penetrated in the base pier 11. One end of the connecting rod 12 is inserted into the connection hole 113 of one base pier 11, and the other end is inserted into the connection hole 113 of the other base pier 11. That is, the connecting rod 12 is used to connect the base piers 11. Optionally, the connecting rod 12 and the base piers 11 are fixed by bolts, and the first groove 112 is opened on the base pier 11. Of course, in other embodiments, a longer base pier 11 may also be directly used as the support base 1.

[0050] In order to fix two juxtaposed support bases 1 and keep their relative positions unchanged, as Figure 3As shown, preferably, the photovoltaic support further includes a fixing rod 4. One end of the fixing rod 4 is connected to the connecting rod 12 of a support base 1, and the other end is connected to the connecting rod 12 of another support base 1. Optionally, two fixing rods 4 are used, and the two fixing rods 4 are arranged at intervals, which can make the relative positions of the two support bases 1 more stable. Optionally, hooks are provided at both ends of the fixing rod 4, and the hooks are adapted to the size of the connecting rod 12, so that the fixing rod 4 hooks the connecting rods 12 at both ends through the hooks at both ends.

[0051] In order to fix two support bases 1 arranged in sequence along the length direction, as Figure 4 shown, preferably, the photovoltaic support further includes a docking rod 5. One end of the docking rod 5 is inserted into the connection hole 113 of a support base 1, and the other end is inserted into the connection hole 113 of another support base 1. Optionally, the docking rod 5 and the base pier 11 of the support base 1 are fixed by bolts.

[0052] Through the arrangement of the fixing rod 4 and the docking rod 5, multiple support bases 1 can be arranged at intervals along their length direction and width direction, and the relative positions can be kept unchanged, forming a support system.

[0053] In order to be adapted to the support and fixation of a single-sided photovoltaic panel 800, as Figure 5 shown, preferably, the photovoltaic support further includes a support frame 6 and a support rod 7. The support frame 6 has a certain height to support the inclined photovoltaic panel 800. A support through hole 61 is formed through the support frame 6. One end of the support rod 7 is inserted into the support through hole 61, and the other end is inserted into the connection hole 113, so that the distance between the support frame 6 and the base pier 11 is fixed. Optionally, the support rod 7 is fixed to both the base pier 11 and the support frame 6 by bolts.

[0054] Optionally, the connecting rod 12, the docking rod 5 and the support rod 7 in the photovoltaic support can be the same kind of rod. The materials of the various components of the photovoltaic support can be aluminum, iron, other alloys or plastics, etc.

[0055] This embodiment also provides a photovoltaic system, including a photovoltaic panel 800 and the above-mentioned photovoltaic support. This photovoltaic system can facilitate the assembly, disassembly and maintenance of the photovoltaic support, and can also facilitate the assembly, disassembly and maintenance between the photovoltaic panel 800 and the photovoltaic support, improving work efficiency.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description.
