Detailed Embodiments

[0020] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0021] It should be noted that the terms used herein are merely for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they specify the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0022] In this embodiment, taking the example of setting 4 solar panels on the mast, the corresponding connecting seats are also 4; of course, in the specific implementation process, the number of solar panels and connecting seats can also be 2, 3, 5 or 6.

[0023] As Figures 1 - 7 shown, a rotatable and foldable solar mast includes a mast column 1, and the upper and lower sections of the mast column 1 are connected by a flange 2. The upper end of the mast column 1 is provided with a number of stacked connecting seats 6, specifically 4. The upper connecting seat can rotate relative to the lower connecting seat; each layer of the connecting seat is provided with a connecting arm extending outward at the side (the 1st connecting arm 12, the 2nd connecting arm 11, the 3rd connecting arm 10, and the 4th connecting arm 9 respectively). Each connecting arm at the outer end is provided with a solar panel 20 that can be turned up and down. The lengths of the connecting arms on each layer of the connecting seats increase layer by layer from bottom to top, so as to ensure that the positions of the solar panels are staggered when they are folded down, and there will be no interference or collision; all the solar panels can be rotated to the same position and then folded. This mast not only realizes the flipping and folding of multiple solar panels in the vertical direction, but also realizes the rotation and closing in the horizontal direction, as Figure 1 shown, it occupies a small space and is convenient for transportation; when in use, after the solar panels are turned up and unfolded, all the solar panels can be dispersed by rotation, avoiding the lower solar panels being blocked by the upper solar panels. The mast can be used in combination with products such as generator sets, mobile lighting trucks, and solar mobile trailers.

[0024] In this embodiment, a thrust ball bearing 21 is provided between the upper connecting seat and the lower connecting seat. A seat hole is provided in the middle of the upper end of the lower connecting seat. A rotating column 8 is provided at the middle of the lower end of the upper connecting seat and extends into the seat hole of the lower connecting seat and can rotate relative to it. The lowermost connecting seat is fixedly connected to the upper end of the mast column; the thrust ball bearing is adopted in the connecting seat rotating structure, and the rotation is easy and smooth.

[0025] In this embodiment, an anti - detachment screw 4 extending into the seat hole is provided on the side of the lower connecting seat. An annular groove for the anti - detachment screw 4 to extend into is provided on the rotating column. The annular groove serves as a safety groove. The embedding of the external anti - detachment screw 4 can prevent the upper connecting seat from being disengaged upward, improving safety. A set screw 7 extending into the seat hole is provided on the side of the lower connecting seat. The set screw 7 is a handle screw. A set hole for cooperating with the set screw is provided on the rotating column. There are two set holes. One is used to lock when the connecting seat rotates to the solar panel unfolding position, and the other is used to lock when the connecting seat rotates to the solar panel folding position. There are four solar panels and connecting seats. After unfolding, the adjacent two solar panels are staggered by 90°. The rotation angle range of the upper connecting seat relative to the lower connecting seat is also 90°. According to the different numbers of solar panels and connecting seats, this angle range is adjusted. The angle range is 360 / n, where n is the number of solar panels and connecting seats.

[0026] In this embodiment, the solar panel 20 is fixedly connected to the fixed frame below it (the four - layer fixed frames are No. 1 fixed frame, No. 2 fixed frame, No. 3 fixed frame, and No. 4 fixed frame). One end of the fixed frame facing the connecting arm is provided with a fixed arm (No. 1 fixed arm 18, No. 2 fixed arm 17, No. 3 fixed arm 16, and No. 4 fixed arm 15 respectively). The fixed arm is hinged to the outer end of the connecting arm. The lengths of the fixed arms of each layer of the fixed frame gradually decrease from bottom to top, and the sum of the lengths of the connecting arms and fixed arms of each layer is the same. This ensures that the lengths of all solar panels extending radially outward are the same when they are swung upward and unfolded, that is, all solar panels are on the same circumference. The connecting arm and the fixed arm are hinged with a bolt 13 as the hinge axis, making it convenient to disassemble and replace the solar panel.

[0027] In this embodiment, two limit holes 22 for fixing the fixed frame in the upper - swing and lower - swing positions respectively are provided at the end of the connecting arm. The distances between the two limit holes and the bolt 13 are the same. One is located below the bolt 13 and the other is beside it, and the two are staggered by 90°. A plum - blossom handle screw 14 is provided in the limit hole. A jack for cooperating with the plum - blossom handle screw is provided on the fixed arm. When the solar panel swings down to the vertical state, the plum - blossom handle screw 14 passes through the lower limit hole and the jack on the fixed arm to fix the solar panel in the lower - swing position. When the solar panel swings up to the horizontal state, the plum - blossom handle screw 14 passes through the upper limit hole and the jack on the fixed arm to fix the solar panel in the upper - swing position.

[0028] In this embodiment, two limit pins 5 are provided on the outer peripheral portion of the upper end of the lower connecting seat at a certain angle offset. A retaining pin 3 is provided on the outer peripheral portion of the lower end of the upper connecting seat between the two limit retaining pins. The two limit pins are respectively used to limit the extreme positions of the rotation of the upper connecting seat. One is used to block the retaining pin when the upper connecting seat rotates to the solar panel deployment position, and the other is used to block the retaining pin when the upper connecting seat rotates to the solar panel closing position; the angle by which the two limit pins 5 are offset is 360 / n, where n is the number of solar panels and connecting seats.

[0029] In this embodiment, a rubber pad 19 is provided on the lower side of the upper fixing frame to prevent collision between the upper and lower adjacent fixing frames.

[0030] The initial state is Figure 1 the fully retracted state in, and the operation process of deploying the solar mast is as follows:

[0031] (1) Remove the plum blossom handle screw on the No. 4 connecting arm, swing the No. 4 mounting frame upward to the horizontal state, then insert the plum blossom handle screw into the upper limit hole and tighten it, as Figure 2 shown;

[0032] (2) Refer to step (2) for the operation of the other three fixing frames to swing up and fix the 4 solar panels, as Figure 4 shown;

[0033] (3) Loosen the set screw on the third-layer connecting seat to release the rotation restriction on the top-layer rotating seat, rotate the solar panel on the top layer 90° with the top-layer connecting seat, and reinsert the set screw on the third-layer connecting seat to fix the top-layer connecting seat, as Figure 5 shown;

[0034] (4) Loosen the set screw on the second-layer connecting seat to release the rotation restriction on the third-layer connecting seat. Refer to step (3) to rotate the solar panel on the third layer 90° with the third-layer connecting seat. Since the top-layer connecting seat and the third-layer connecting seat have been fixed to each other by the set screw, the top-layer connecting seat can be driven to rotate 90 degrees simultaneously when the third-layer connecting seat rotates, as Figure 6 shown;

[0035] (5) Loosen the set screw on the lowermost connecting seat to release the rotation restriction on the second-layer connecting seat. Refer to the above steps to rotate and fix the second-layer solar panel, and the final effect is as Figure 7 shown.
