[0024] The present invention will be further described below with reference to the following embodiments. The following embodiments are provided solely to facilitate understanding of the present invention. It should be noted that, within the scope of the present invention, modifications may be made by a person skilled in the art without departing from the principles of the present invention. Such improvements and modifications are also within the scope of the claims of the present invention.

[0025] Example 1:

[0026] To address the challenges of existing technologies, this utility model utilizes 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, this utility model can significantly improve the deployment flexibility and space efficiency of photovoltaic systems while reducing overall system costs and maintenance requirements.

[0027] Specifically, such as Figure 1 and Figure 2 As shown, the utility model provides a foldable electric photovoltaic support, comprising: a base 6, a multi-stage electric push rod and a photovoltaic panel 19;

[0028] 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 provided 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 through forward and reverse rotation; the folding photovoltaic panel assembly is unfolded and folded as the multi-stage electric push rod is extended and retracted.

[0029] 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 provided 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.

[0030] The photovoltaic panel fixings include a first photovoltaic panel fixing 3, a second photovoltaic panel fixing 4, and a third photovoltaic panel fixing 5. These fixings are mounted on the housing surface of each node of the multi-stage electric actuator and interlock with the photovoltaic panel connector. When the multi-stage electric actuator retracts and folds the photovoltaic panel, the maximum folding angle of the photovoltaic panel is limited. The fixings are also secured to the mounting holes on the back of the photovoltaic panel using fasteners. Compared to welding, the use of fasteners prevents the warranty of the photovoltaic panel from being voided due to artifacts caused by welding.

[0031] Base fixings 7 are also provided on both sides of the base 6; these fixings 7 are used to secure the foldable electric photovoltaic support, and the height of the fixings 7 is adjustable. By adjusting the height of the fixings 7 on both sides, the inclination angle of the support can be freely adjusted to match the angle required by the photovoltaic panel for different maximum light irradiation in different regions.

[0032] Example 2:

[0033] Based on 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;

[0034] In which, 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 provided 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 as the multi-stage electric push rod extends and retracts.

[0035] The base 6 is connected to multi-stage electric push rods on both sides via bearing blocks 13. The base 6 has a hollow interior, which houses components such as a first pulley 9, a synchronous belt 10, a second pulley 11, and a round nut 12. The motor 8 is connected to the first pulley 9, which is then connected to the second pulley 11 via the synchronous belt 10. The second pulley 11 is mounted on the bearing block 13 via the round nut 12, making the structure more stable, firm, and safer. The bearing block 13 contains a deep groove ball bearing to support radial loads.

[0036] The multi-stage electric push rod is provided with a multi-stage lead screw inside. Except for the bottom lead screw, each lead screw has a nested thread that matches the other lead screws. The upper lead screw is sleeved on the lower 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.

[0037] The first lead screw 14 is connected to the second lead screw 17 via a trapezoidal lead screw 15 and a nut connecting ring 16 in a direction away from the base 6. For example, the end of the lead screw away from the motor 8 is equipped with a 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, Figure 5 As shown, the trapezoidal screw 15 consists of a trapezoidal screw shaft portion 151 and a trapezoidal screw shaft nut portion 152. One end of the trapezoidal screw shaft nut portion 152 is fixed to the end plate, while the other end is fixed to the nut connecting ring 16. Furthermore, the end of the second screw 17 has an inner ring with a smaller outer diameter than the first screw 14, and the nut connecting ring 16 has a protrusion that matches the outer diameter of the inner ring, which precisely engages the second screw 17. Therefore, when the first screw 14 rotates, it drives the trapezoidal screw 15. The upward movement of the trapezoidal screw 15 also causes the end plate and nut connecting ring 16 to rise. The hollow interior of the second screw 17 matches the outer shape of the first screw 14. The first screw 14 is keyed inside the second screw 17, driving the second screw 17 to rotate together. The same principle applies to subsequent push rods, which are pushed out by the rotation of the previous screw. The movement of the push rods causes the photovoltaic panel mounting components fixed to them to move synchronously, thereby achieving the purpose of unfolding or folding the photovoltaic panels.

[0038] It should be noted that the parts in this embodiment that are the same or similar to those in Example 1 can be referenced to each other and will not be described in detail in this application.

[0039] Example 3:

[0040] Based on Example 2, Example 3 of the present application provides a working method of a foldable electric photovoltaic support, including:

[0041] Step 1: Adjust the height of the base fixing member 7 according to the target bracket inclination angle.

[0042] 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.

[0043] 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.

[0044] Step 3: The second pulley 11 rotates to drive the first screw 14 to rotate synchronously. When the first screw 14 rotates, it drives the trapezoidal screw 15 to move. The trapezoidal screw 15 rises and drives the end plate and the nut connecting ring 16 to rise;

[0045] 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 achieving the extension of the multi-stage electric push rod;

[0046] 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.

[0047] 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.
