[0040] See also Figure 1-Figure 7 The embodiment of the utility model provides a solar photovoltaic support structure, including a support frame 1, a fixing frame 3, and one or more telescopic components 2; the support frame 1 can be hinged on the fixing frame 3 to rotate up and down, and the support frame 1 is provided with a accommodating structure for accommodating solar photovoltaic panels on a side opposite to the fixing frame 3, and the fixing frame 3 is used to be fixed on the wall 4, and the position of the fixing frame 3 away from the hinge point is rotatably connected to the lower part of the telescopic component 2; the upper part of the telescopic component 2 is detachably connected to the position of the support frame 1 away from the hinge point, and the telescopic component 2 is connected to the support frame 1 and changes the angle between the support frame 1 and the fixing frame 3 when it is extended. The above can realize the effect of convenient angle adjustment, which is more conducive to the light collection of the solar panel. When the upper part of the telescopic component 2 is removed from the support frame 1, the support frame 1 can also be completely closed, which is convenient for protecting the solar panel, thereby increasing the life of the solar panel.

[0041] In some embodiments, a snap-fit ​​structure 24 is further included, which is fixed to the fixing frame 3 or the wall 4. When the upper portion of the telescopic component 2 is removed from the supporting frame 1, it is rotated and pressed into the snap-fit ​​structure 24 for storage, thereby protecting the telescopic component 2.

[0042] In some embodiments, the telescopic component 2 includes more than two telescopic rods 21, and the more than two telescopic rods 21 are mutually connected to adapt to different length requirements to achieve different opening and closing angles of the support frame, which is beneficial to the light collection of the solar panel.

[0043] In some embodiments, the telescopic component 2 includes more than two telescopic rods 21, which are nested with each other, wherein the telescopic rod 21 on the side of the telescopic component 2 close to the fixed frame 3 is thinner than the telescopic rod 21 on the side close to the support frame 1, and so on. The telescopic rod 21 on the side of the telescopic component 2 closest to the support frame 1 is the thickest, thereby achieving the purpose of mutual nesting and adapting to different length requirements, so as to achieve different opening and closing angles of the support frame 1, which is beneficial to the light collection of the solar panel.

[0044] In some embodiments, an adjusting and fixing mechanism for adjusting the telescopic length is provided between the two or more telescopic rods 21 , and the adjusting and fixing mechanism is used to adjust the telescopic length and fix the length of the telescopic component 2 .

The elevated fixing seat 311 is used to increase the spacing distance between the support frame 1 and the fixing frame 3 at the hinge. When the support frame 1 is closed, the buffer structure 5 can better play a buffering role, which is also conducive to the support frame 1 to be closed more matchingly relative to the fixing frame 3 and the wall 4.

In this way, it is sufficient to first install the wall fixing part 301, and then place the fixing frame 3 in the opening or the opening of the wall fixing part 301, so the structural setting of the wall fixing part 301 plays a role in facilitating the installation or removal of the fixing frame 3. Preferably, the wall fixing part 301 is fixed to the wall 4 by an expansion bolt 321.

[0051] In some embodiments, the fixing frame 3 is a square frame and the telescopic component 2 is hinged to the inner two sides of the fixing frame 3; or the fixing frame 3 is a T-shaped frame consisting of a horizontal bar and a vertical bar and the telescopic component 2 is hinged to the lower part of the vertical bar.
