DETAILED DESCRIPTION

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0056] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0057] See also Figure 1-3 As shown, the present invention is a telescopic foldable support frame for a photovoltaic component, comprising a photovoltaic component; the photovoltaic component comprises a first photovoltaic panel 1, a second photovoltaic panel 2, and a third photovoltaic panel 3 connected by a hinge A10; and when the photovoltaic component is in the unfolded state, the upper surfaces of the first photovoltaic panel 1, the second photovoltaic panel 2, and the third photovoltaic panel 3 are parallel; in order to facilitate the storage of the first photovoltaic panel 1, the second photovoltaic panel 2, and the third photovoltaic panel 3, so as to reduce the unfolded size of the photovoltaic component in the stored state, protruding bosses A11 and bosses B31 are respectively provided on the upper surfaces of the adjacent sides of the first photovoltaic panel 1 and the third photovoltaic panel 3; the boss A11 and the boss B31 are connected by at least two hinges A10, and the sum of the protruding heights of the boss A11 and the boss B31 is the same as the thickness of the first photovoltaic panel 1, and when the photovoltaic component is in the stored state, the second photovoltaic panel 2 is located between the first photovoltaic panel 1 and the third photovoltaic panel 3, and the three-fold photovoltaic panel achieves zero-gap overlap through the cooperation of the boss A and the boss B.

[0058] In order to control the movement of the photovoltaic components in the storage state, rollers 3 are installed on the four corners of the bottom of the second photovoltaic panel 2 through the mounting platform 12. The setting of the rollers 3 makes it convenient to drag the photovoltaic components along the ground for movement according to needs during use.

[0059] At the same time, in order to facilitate the support of the photovoltaic module during use, the present invention also provides a support frame connected below the photovoltaic module, and the photovoltaic module is supported by the support frame.

[0060] Specifically, a bottom beam 20 is connected to the bottom of the first photovoltaic panel 1. At this time, the support frame includes two pillars 4 that are hingedly connected to the two ends of the bottom beam 20 through hinges B100. When in use, the control pillars 4 are rotated in directions away from each other under the action of the hinges B100 to control the two pillars 4 to be unfolded. When the control pillars 4 are rotated in directions close to each other under the action of the hinges B100, the control pillars 4 are retracted.

[0061] like Figure 6-7 The pillar 4 includes a pillar body 40, a mounting cavity 41 is provided on one side of the pillar body 40, and a pad 45 having a stud A46 is connected to the bottom of the mounting cavity 41; Figure 13-17, the installation cavity 41 is rotatably connected to the telescopic rod 7; the ends of the two telescopic rods 7 are respectively installed with three gap-set connecting plates A71 and connecting plates B72; openings A73 are provided on the connecting plates A71 and B72; when the pillars 4 are unfolded, they are flipped so that the two pillars 4 are parallel and perpendicular to the length direction of the bottom beam 20, and the two telescopic rods 7 are controlled to extend to the connecting plates A71 and B72 for plugging; at this time, the control pin 74 passes through the openings A73 set on the connecting plates A71 and B72, and the bolt 75 is connected to the end of the pin 74, and then the two telescopic rods 7 are used. The setting of the two telescopic rods 7 is used to achieve the following when in use by controlling the connecting plates A71 and B72 at the ends of the telescopic rods 7. Figure 17 After the matching is performed as shown, the positions of the two pillars 4 in the unfolded state are limited to prevent the pillars 4 from being turned over along the hinge B100 for storage due to external force or other effects.
