In this way, the fixed mode between the articulated connector and the inclined beam has two kinds, one is that the bottom fixing bolt hole is fixed with the inclined beam by a bottom fixing bolt, and the other is that the lateral fixing bolt hole is fixed with the inclined beam by a lateral fixing bolt. If the bottom fixing bolt may interfere with the photovoltaic module, the lateral fixing bolt is used for fixing.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0038] like Figures 1 to 5As shown, a photovoltaic support includes an inclined beam 2, a support member 3, and a hinged connector 1. The inclined beam 2 extends longitudinally and has a crossbeam on it, on which photovoltaic modules are mounted. The hinged connector 1 is hinged to the support member 3 and fixed to the inclined beam 2. The hinged connector 1 includes a hinge part 11 that is hinged to the support member 3 and a fixing part 12 that is fixed to the inclined beam 2. The fixing part 12 has a fixing groove that matches the shape of the inclined beam. For example, if the cross-section of the inclined beam is rectangular, then the fixing groove is also a rectangular groove. The bottom of the fixing groove has a bottom fixing bolt hole 14, and the two side walls of the fixing groove have lateral fixing bolt holes 13, which can be used to connect with the bottom fixing bolt 6 and the lateral fixing bolt 4, respectively. Of course, bolt holes are also provided at corresponding positions on the inclined beam for connecting with the bottom fixing bolt 6 and the lateral fixing bolt 4.

[0039] In this embodiment, there are two ways to fix the hinged connector 1 to the inclined beam 2, such as... Figure 1 As shown, one method involves using lateral fixing bolts 4 to fix the lateral fixing bolt hole 13 to the inclined beam 2; for example... Figure 2 As shown, another method involves using bottom fixing bolts 6 to fix the bottom fixing bolt hole 14 to the inclined beam 2. In this way, if the bottom fixing bolts might interfere with the photovoltaic module, lateral fixing bolts can be used for fixation. Since bolts can be used to fix the hinged connector to the inclined beam in either of two directions, the problem of interference with the photovoltaic module in a single direction is solved.

[0040] Furthermore, the inclined beam 2 is connected to at least two hinged connectors 1 along its extension direction. If there are many connection points between the inclined beam and the support, many bolt holes will be drilled on the inclined beam. To avoid drilling bolt holes on the same side of the inclined beam, which would weaken its strength, the inclined beam 2 is connected to two adjacent hinged connectors 1, such as... Figure 1 As shown, the first one is fixed using a lateral fixing bolt 4; specifically, two lateral fixing bolts 4 can be used. Figure 2 As shown, the second one is fixed using bottom fixing bolts 6, specifically two bottom fixing bolts 6 can be used; correspondingly, the bolt holes for the connection with the side fixing bolts are opened on the side wall of the inclined beam, and the bolt holes for the connection with the bottom fixing bolts are opened on the bottom wall of the inclined beam. The inclined beam alternately drills bolt holes on the bottom wall and side wall along its extension direction, so that the bolt holes are not drilled on the same side of the inclined beam, reducing the concentrated weakening of the inclined beam's strength.

[0041] In this embodiment, the bottom fixing bolt hole 14 and the side fixing bolt hole 13 are both oblong holes. The bolt holes on the inclined beam corresponding to the bottom fixing bolt hole 14 and the side fixing bolt hole 13 can be round holes.

[0042] Specifically, the hinge part 11 is provided with a hinge groove, and a hinge bolt 5 is connected between the opposite side walls of the hinge groove. The end of the support member is inserted into the hinge groove and connected to the hinge bolt 5. The side wall of the hinge groove is provided with an isosceles triangular portion, and the hinge bolt 5 is connected to the apex of the isosceles triangular portion, which facilitates the hinge connection between the hinge part and the support member. A hinge hole 15 is provided at the apex of the isosceles triangular portion to connect with the hinge bolt 5.

[0043] like Figure 5 As shown, the hinge connector 1 has an H-shaped structure. Preferably, the hinge connector 1 is a one-piece profile. Because the hinge connector is a one-piece profile, such as stainless steel or aluminum alloy, sufficient structural strength can be ensured, and costs can be reduced. The H-shaped structure of the hinge connector creates a fixing groove and a hinge groove on opposite sides.

[0044] It is understood that the inclined beam 2 and the support member 3 can be made of the same materials as in the prior art, for example, the inclined beam 2 is made of U-steel or C-steel. The support member 3 is made of U-steel or C-steel.

[0045] It is understandable that the aforementioned support components can be as follows: Figure 1 and Figure 2 As shown, it can be a diagonal brace that intersects the inclined beam perpendicularly, or it can be a column.

[0046] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the utility model will be included within the scope of the claims.
