[0037] Please refer to Figure 1 , Figure 1 is a structural schematic diagram of a photovoltaic panel assembly disclosed by the embodiments of the present disclosure. The embodiments of the present disclosure provide a photovoltaic panel assembly 1. It comprises a photovoltaic panel 10, three universal connecting pieces 20, and three driving mechanisms 30. Among them, the three universal connecting pieces 20 are arranged on the back surface 10a of the photovoltaic panel 10, and the three universal connecting pieces 20 are arranged in an isosceles triangle; the three driving mechanisms 30 are respectively connected with the three universal connecting pieces 20, and are used for adjusting the orientation of the photovoltaic panel 10.

[0038] It can be understood that the photovoltaic panel assembly 1 provided by the embodiments of the present disclosure is applied to convert solar energy into electric energy. Among them, the panel surface of the photovoltaic panel 10 is used for receiving solar energy, so as to convert solar energy into electric energy; the driving mechanism 30 is installed on the back surface 10a of the photovoltaic panel 10, so as to support the photovoltaic panel 10, adjust the height of the photovoltaic panel 10 and the orientation of the panel surface of the photovoltaic panel 10.

[0039] It is understandable that, in the use of the photovoltaic panel assembly 1, the panel surface of the photovoltaic panel 10 should be as possible perpendicular to the direction of the sun's radiation, so that the photovoltaic panel 10 can obtain higher energy conversion efficiency. Therefore, the photovoltaic panel in the related art is usually installed with the panel surface facing south and inclined at a certain angle, so as to absorb more solar radiation. On this basis, some photovoltaic panels are fixed with a support on the back surface thereof to adjust the longitude angle, so that the photovoltaic panel can change the orientation with the daily rising and setting of the sun, thereby making the panel surface of the photovoltaic panel face the sun to a greater extent. However, the latitude angle of the sun is different in different seasons, and the existing photovoltaic panel support is difficult to adjust the latitude angle of the photovoltaic panel.

[0040] The photovoltaic panel assembly 1 provided by the embodiment is provided with three universal connecting pieces 20 arranged in an isosceles triangle on the back surface 10a of the photovoltaic panel 10, and three driving mechanisms 30 are connected with the three universal connecting pieces 20 respectively, for adjusting the orientation of the photovoltaic panel 10. It is understandable that the three driving mechanisms 30 can drive the universal connecting pieces 20 to displace respectively, thereby cooperating to adjust the height, longitude angle and latitude angle of the photovoltaic panel assembly 1. When the front of the panel surface of the photovoltaic panel 10 encounters an obstruction, the photovoltaic panel 10 can be adjusted to be higher to avoid the obstruction; when encountering severe weather such as strong wind, hail and blizzard, the photovoltaic panel 10 can be adjusted to be lower, and at the same time, the photovoltaic panel 10 is adjusted to be parallel to the ground to reduce the wind resistance, thereby effectively preventing the damage of the wind force to the device.

[0041] Among them, the three universal connecting pieces 20 are arranged in an isosceles triangle, so that the driving mechanism 30 can provide stable support for the photovoltaic panel 10. In some embodiments, the photovoltaic panel 10 is a rectangular photovoltaic panel, wherein two universal connecting pieces 20 are arranged close to two adjacent corners of the rectangle, and the third universal connecting piece 20 is arranged at the midpoint position of the opposite side of the rectangle. In the above embodiment, the distance between the two universal connecting pieces 20 is greater, so that the support of the driving mechanism 30 to the photovoltaic panel 10 is more stable, and at the same time, the accuracy of the angle adjustment of the driving mechanism 30 to the photovoltaic panel 10 is higher.

[0042] Please refer to Figure 2 and Figure 3 , Figure 2 is a front view structural schematic diagram of the photovoltaic panel assembly disclosed by the embodiment of the present disclosure; Figure 3 is a structural schematic diagram of the driving mechanism. In some embodiments, each driving mechanism 30 includes a lead screw 31, a nut block 32 and a driving rod 33, the nut block 32 is arranged on the lead screw 31, and the driving rod 33 is connected with the universal connecting piece 20 at one end and connected with the nut block 32 at the other end; the three lead screws 31 of the three driving mechanisms 30 are arranged in parallel and at intervals.

[0043] It can be understood that when the photovoltaic panel assembly 1 disclosed in the embodiment adjusts the panel surface direction of the photovoltaic panel 10, the screw nut slider 32 slides along the screw rod 31, thereby driving the driving rod 33 to move, and the three driving rods 33 jointly realize the adjustment of the angle and height of the photovoltaic panel 10.

[0044] The three screw rods 31 of the three driving mechanisms 30 are arranged in parallel and at intervals, so that the driving mechanism 30 provided in the embodiment can provide more stable support for the photovoltaic panel 10.

[0045] It can be understood that the side of the driving rod 33 facing the photovoltaic panel 10 comprises a connecting portion 332, and the connecting portion 332 is rotationally connected with the universal connecting piece 20, so that the driving rod 33 can rotate in various directions relative to the universal connecting piece 20.

[0046] Please refer again to Figure 2 and Figure 3 . In some embodiments, the three screw rods 31 are arranged at equal intervals; and / or the screw nut slider 32 on the middle screw rod 31 is connected with the universal connecting piece 20 located at the top corner of the isosceles triangle through the driving rod 33.

[0047] It can be understood that the equal interval arrangement of the three screw rods 31 enables the driving mechanism 30 provided in the embodiment to provide more stable support for the photovoltaic panel 10. In some embodiments, the distance between the two farthest screw rods 31 is the distance between the two universal connecting pieces 20 located at the bottom side of the isosceles triangle in the isosceles triangle arrangement.

[0048] The screw nut slider 32 on the middle screw rod 31 is connected with the universal connecting piece 20 located at the top corner of the isosceles triangle through the driving rod 33, so that the driving mechanism 30 of the photovoltaic panel assembly 1 in the embodiment is symmetrical. When the screw nut sliders 32 of the two driving mechanisms 30 on the two sides are fixed, adjusting the screw nut slider 32 of the driving mechanism 30 at the middle position can realize the adjustment of the longitude angle of the photovoltaic panel 10.

[0049] Please refer again to Figure 3 , and refer to Figure 4 , Figure 4 is Figure 3 the partial structure schematic view of the driving mechanism I part shown in the figure.

[0055] Please refer to Figure 3 and Figure 5 . In some embodiments, each driving mechanism 30 further includes a servo motor 35, which is connected to one end of the lead screw 31 and is used to drive the lead screw 31 to rotate, so as to drive the nut block 32 to slide along the lead screw 31.

[0056] It can be understood that the photovoltaic panel assembly 1 provided by the present embodiment can be electrically driven and adjusted by the servo motor 35. When the photovoltaic panel assembly 1 disclosed by the present embodiment adjusts the angle and height of the photovoltaic panel 10, the servo motor 35 drives the lead screw 31 to rotate, so as to drive the nut block 32 to slide along the lead screw 31; the three nut blocks 32 respectively drive the three driving rods 33 to move and rotate around the fish-eye joint 321, so as to control the orientation and height of the photovoltaic panel 10.

[0057] In some embodiments, the servo motor 35 is further electrically connected with an external control device, so as to realize the electrical signal transmission between the servo motor and the external control device. The external control device can calculate the optimal angle and optimal height of the photovoltaic panel 10 according to the sun angle, wind direction and wind force information, so as to guide the servo motor to drive the lead screw 31 to rotate and drive the nut block 32 to slide, and realize the automatic regulation and control of the height and angle of the photovoltaic panel 10.

[0058] Please refer to Figure 3In some embodiments, the three servo motors 35 are fixed on the same side of the three lead screws 31, so that the wiring of the servo motors 35 is more convenient and clear.
