[0031] The present invention is further described below in conjunction with embodiments. The description of the following embodiments is only used to help understand the present invention. It should be noted that for ordinary persons in the art, without departing from the principle of the present invention, the present invention can also be modified in some ways, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.

[0032] Embodiment 1:

[0033] To solve the problems of the prior art, the present invention adopts a multi-stage telescopic electric push rod design to provide an innovative solution for the rapid deployment and efficient folding of photovoltaic modules. By applying this technology to the deployment and folding of photovoltaic modules, the present invention can significantly improve the deployment flexibility and space efficiency of the photovoltaic system, while reducing the overall cost and maintenance requirements of the system.

[0034] Specifically, Figure 1 and Figure 2 As shown, the present invention provides a foldable electric photovoltaic support, comprising: a base 6, a multi-stage electric push rod and a photovoltaic panel 19;

[0035] Among them, the base 6 can provide a convenient fixing platform, and multi-stage electric push rods are connected to both sides of the base 6, and the multi-stage electric push rods are connected to the folding photovoltaic panel assembly through the photovoltaic panel fixing parts; a motor 8 is arranged at the bottom of the multi-stage electric push rod, and the motor 8 drives the multi-stage electric push rod to extend and retract by forward and reverse rotation; the folding photovoltaic panel assembly is unfolded and folded as the multi-stage electric push rod is extended and retracted.

[0036] The folding photovoltaic panel assembly is composed of multiple photovoltaic panels 19, and a first photovoltaic panel connector 1 and a second photovoltaic panel connector 2 are arranged on both sides of each photovoltaic panel 19. The first photovoltaic panel connector 1 and the second photovoltaic panel connector 2 are both fixed on the mounting holes of the photovoltaic panel 19; the two photovoltaic panels 19 are hinged to each other by the first photovoltaic panel connector 1 and the second photovoltaic panel connector 2.

[0037] The photovoltaic panel fixing parts include a first photovoltaic panel fixing part 3, a second photovoltaic panel fixing part 4 and a third photovoltaic panel fixing part 5; the first photovoltaic panel fixing part 3, the second photovoltaic panel fixing part 4 and the third photovoltaic panel fixing part 5 are arranged on the shell surface of each node of the multi-stage electric push rod, and are hinged with the photovoltaic panel connecting part. When the multi-stage electric push rod shrinks the photovoltaic panel and folds it up, the maximum folding angle of the photovoltaic panel is limited. The fixing parts are also fixed to the mounting holes on the back of the photovoltaic panel using fasteners. Compared with welding fixing, the use of fasteners can prevent the warranty of the photovoltaic panel from being invalidated due to artificial welding fixing.

[0038] Base fixing parts 7 are also provided on both sides of the base 6; the base fixing parts 7 are used to fix the foldable electric photovoltaic bracket and the height of the base fixing parts 7 is adjustable. By adjusting the height of the base fixing parts 7 on both sides, the inclination angle of the bracket can be freely set to match the angle required by the photovoltaic panel for different maximum light irradiation in different regions.

[0039] Embodiment 2:

[0040] On the basis of Example 1, Example 2 of the present application provides a more specific foldable electric photovoltaic support, including: a base 6, a multi-stage electric push rod and a photovoltaic panel;

[0041] Among them, multi-stage electric push rods are connected to both sides of the base 6, and the multi-stage electric push rods are connected to the folding photovoltaic panel assembly through the photovoltaic panel fixing parts; a motor 8 is arranged at the bottom of the multi-stage electric push rod, and the motor 8 is used to drive the multi-stage electric push rod to extend and retract; the folding photovoltaic panel assembly is unfolded and folded with the extension and retraction of the multi-stage electric push rod.

[0042] The two sides of the base 6 are connected to multi-stage electric push rods through the bearing seat 13. The base 6 is hollow inside and is used to set the first pulley 9, the synchronous belt 10, the second pulley 11 and the round nut 12 and other components; the motor 8 is connected to the first pulley 9; the first pulley 9 is connected to the second pulley 11 through the synchronous belt 10; the second pulley 11 is installed on the bearing seat 13 through the round nut 12, making its structure more stable, firm and safer. The bearing seat 13 contains a deep groove ball bearing to provide radial load support.

[0043] The multi-stage electric push rod is provided with a multi-stage lead screw inside. Except for the bottom lead screw, each stage of the lead screw has a nested thread that matches other lead screws. The upper stage lead screw is sleeved inside the lower stage lead screw in increasing layers. The first lead screw 14 near the end of the base 6 is fixed in the second pulley 11 through a keyway and rotates synchronously with the second pulley 11.

[0044] The first lead screw 14 is connected to the second lead screw 17 through the trapezoidal lead screw 15 and the nut connecting ring 16 in the direction away from the base 6. For example, the end of the lead screw away from the motor 8 is equipped with the trapezoidal lead screw 15, and the end close to the motor 8 is provided with a connecting groove for fixing the nut connecting ring 16, and the nut connecting ring 16 fixes the trapezoidal lead screw 15. Specifically, as Figure 5 As shown, the trapezoidal lead screw 15 is composed of a trapezoidal lead screw part 151 and a trapezoidal lead screw nut part 152. One end of the trapezoidal lead screw nut part 152 is fixed to the end plate, and the other end is fixed to the nut connecting ring 16. In addition, the end of the second lead screw 17 has an inner ring smaller than the outer diameter, and the nut connecting ring 16 has a protrusion that matches the outer diameter of the inner ring, just clamping the second lead screw 17. Therefore, when the first lead screw 14 rotates, the trapezoidal lead screw 15 is driven to move, and the rise of the trapezoidal lead screw 15 drives the end plate and the nut connecting ring 16 to rise. The hollow shape inside the second lead screw 17 matches the shape of the first lead screw 14, and the first lead screw 14 is keyed inside the second lead screw 17 to drive the second lead screw 17 to rotate together. The same is true for the subsequent push rods of each level, which are pushed out by the rotation of the upper lead screw. The movement of the push rod drives the photovoltaic panel fixings fixed on the push rod to move synchronously to achieve the purpose of unfolding or folding the photovoltaic panel.

[0045] It should be noted that the parts in this embodiment that are the same or similar to those in Embodiment 1 can be referenced to each other and will not be described in detail in this application.

[0046] Embodiment 3:

[0047] Based on Example 2, Example 3 of the present application provides a working method of a foldable electric photovoltaic support, including:

[0048] Step 1: Adjust the height of the base fixing member 7 according to the target bracket inclination angle.

[0049] It should be noted that the photovoltaic bracket is in a folded and stowed state by default. When necessary, the base fixing member 7 is first fixed so that the inclination angle of the bracket meets the pre-calculated angle.

[0050] Step 2, start the motor 8, the motor 8 drives the first pulley 9 to rotate, and the first pulley 9 drives the second pulley 11 to rotate through the synchronous belt 10.

[0051] Step 3, the second pulley 11 rotates to drive the first screw 14 to rotate synchronously, and the first screw 14 rotates to drive the trapezoidal screw 15 to move, and the trapezoidal screw 15 rises to drive the end plate and the nut connecting ring 16 to rise;

[0052] Step 4: The second lead screw 17 rotates under the action of the first lead screw 14 to push the push rod out, and drives the subsequent lead screws to rotate, thereby realizing the extension of the multi-stage electric push rod;

[0053] Step 5: The extension of the multi-stage electric push rod drives the synchronous movement of the folding photovoltaic panel assembly fixed on the push rod to unfold each photovoltaic panel 19.

[0054] Specifically, the method provided in this embodiment is the working method corresponding to the device provided in Example 2. Therefore, the parts in this embodiment that are the same or similar to those in Example 2 can be referenced to each other and will not be repeated in this application.
