[0046] In the embodiment of the present disclosure, the control mechanism 5 further comprises a functional gear 505, and the functional gear 505 is arranged in the inside of the holding cylinder 502, the functional gear 505 is rotationally connected to the side of the synchronous gear ring 503, the side of the positioning main shaft 601 and the driven auxiliary shaft 602 are both provided with a linkage gear 6011, the two sides of the functional gear 505 are respectively in gear transmission with the gear teeth of the linkage gears 6011 of the positioning main shaft 601 and the driven auxiliary shaft 602, in use, when the photovoltaic panel 8 is in the normal use state, at this time, the positioning mechanism 6 is in the unfolded state, the electric push rod 404 is in the elongated state when the positioning mechanism 6 is in the unfolded state, and at this time, the top of the positioning column 506 is abutted against the longitudinal abutment plate 4031 of the top rod 403, the bottom of the positioning column 506 is provided with a positioning tension spring 5061, and the two ends of the positioning tension spring 5061 are respectively fixedly connected to the bottom of the positioning column 506 and the bottom of the positioning seat 501, so that the positioning tension spring 5061 is in the elongated state, under the gear meshing effect of the positioning rack 5062 and the synchronous gear ring 503, the use angle of the holding cylinder 502 is fixed, at this time, the abutment column 504 is in the state of extending out of the holding cylinder 502 under the effect of the unfolded top spring 5041, so that the included angle between the protective plates 7 of the positioning main shaft 601 and the driven auxiliary shaft 602 is one hundred and eighty degrees under the effect of the linkage protrusions 6012 and the linkage grooves 5042, so that the positioning mechanism 6 is in the unfolded state, the photovoltaic panel 8 can achieve the maximum illumination area when the positioning mechanism 6 is in the unfolded state, the photoelectric conversion efficiency is improved, the use is stable, and the power generation efficiency is high.

[0047] In the embodiments of the present disclosure, the side surface of the abutting column 504 is provided with a spread top spring 5041, and the two ends of the spread top spring 5041 are respectively abutted against the side surface of the abutting column 504 and the inside of the positioning main shaft 601. In use, the positioning mechanism 6 can adjust the use angle of the photovoltaic panel 8 through the positioning column 506, so as to adapt to the use under different environmental illumination conditions. When the positioning mechanism 6 is in the spread state and the electric push rod 404 is in the telescopic state, the positioning seat 501 can change the use position by following the telescopic movement of the electric push rod 404. However, since the top of the positioning column 506 is abutted against by the longitudinal abutting plate 4031, the positioning column 506 cannot move by following the movement of the positioning seat 501. The side surface of the positioning column 506 is provided with a positioning rack 5062, and the positioning rack 5062 and the gear teeth of the synchronous gear ring 503 are in meshing transmission, so that when the positioning seat 501 is lifted and lowered, the positioning rack 5062 can drive the holding cylinder 502 to rotate through the synchronous gear ring 503, and at the same time, the function gear 505 will also rotate by following the synchronous gear ring 503. Under the positioning effect of the abutting column 504, the positioning main shaft 601 can always keep the current spread state of the side surface protection plate 7. Also under the effect of the function gear 505, the driven auxiliary shaft 602 can also keep the spread state of the side surface protection plate 7 through the positioning main shaft 601, that is, the holding cylinder 502, the abutting column 504 and the positioning mechanism 6 can keep as a whole to rotate, so as to change the inclination angle of the protection plate 7, that is, the use angle of the photovoltaic panel 8. The adjustment is convenient, the use is flexible, and the flexibility and adaptability are extremely strong.

[0048] In the embodiment of the present disclosure, the inside of the positioning main shaft 601 is provided with a linkage protrusion 6012, the outside of the abutting column 504 is provided with a linkage groove 5042, and the linkage protrusion 6012 is inserted into the inside of the linkage groove 5042. In use, the positioning mechanism 6 also has a folded use state.

When it is needed to switch the positioning mechanism 6 to the folded state, the electric push rod 404 only needs to be continuously retracted. In the initial stage of retraction, the positioning seat 501 is driven to move downward, so that the top of the positioning column 506 loses the abutting and blocking relationship with the longitudinal abutting plate 4031, so that the use angle of the protective plate 7 can be switched to the horizontal state under the action of the positioning tension spring 5061. The side surface of the abutting side rod 402 is provided with a switching inclined surface 4021 arranged obliquely. Under the action of the unfolding top spring 5041, the abutting column 504 always abuts against the rod body side surface of the abutting side rod 402. When the electric push rod 404 is continuously retracted subsequently, the switching inclined surface 4021 will abut and press the abutting column 504, so that the abutting column 504 moves to the inside of the retaining cylinder 502 and compresses the unfolding top spring 5041. When the abutting column 504 moves, the linkage groove 5042 can drive the positioning main shaft 601 to rotate through the linkage protrusion 6012, so that the protective plate 7 on the side surface of the positioning main shaft 601 is switched to the vertical state for use. When the positioning main shaft 601 rotates, the driven auxiliary shaft 602 will also rotate in the opposite direction synchronously under the action of the meshing of the linkage gear 6011 and the function gear 505, so that the protective plate 7 on the side surface of the driven auxiliary shaft 602 is switched to the vertical state for use. Then the top surfaces of the two protective plates 7 will abut against each other, protecting and hiding the photovoltaic panel 8, so that the photovoltaic panel 8 has very high anti-impact and bumping capacity and is stable in use. When it is needed to switch the positioning mechanism 6 to the unfolded state for use again, the electric push rod 404 only needs to be continuously elongated.

eighty degrees under the action of the linkage protrusion 6012 and the linkage groove 5042, so that the positioning mechanism 6 is in the unfolded state, when the positioning mechanism 6 is in the

rack 5062 can drive the retaining cylinder 502 to rotate through the synchronous gear ring 503 when the positioning seat 501 is lifted, and the functional gear 505 also rotates with the synchronous

8, the positioning mechanism 6 also has a folding use state, the photovoltaic panel 8 can be hidden in the inside of the two mutually adhered protective plates 7 when the positioning mechanism 6 is in the folded state, so that the photovoltaic panel 8 can be protected through the outside of the protective plate 7, so as to avoid the damage of the photovoltaic panel 8 caused by foreign matter collision in the harsh weather environment,When it is needed to switch the positioning mechanism 6 to the folded state, it is only needed to control the electric push rod 404 to continuously contract, and the electric push rod 404 drives the positioning seat 501 to move downward in the initial contraction stage, so that the top of the positioning column 506 loses the abutting and blocking relationship with the longitudinal abutting plate 4031, and under the action of the positioning tension spring 5061, the use angle of the protective plate 7 can be switched to the horizontal state,

retaining cylinder 502 and compresses the unfolded top spring 5041, when the abutting column 504 moves, the linkage groove 5042 can drive the positioning main shaft 601 to rotate through the linkage protrusion 6012, so that the protective plate 7 on the side of the positioning main shaft 601 is switched to the vertical state for use, when the positioning main shaft 601 rotates, the driven auxiliary shaft 602 also rotates in the opposite direction synchronously under the tooth meshing action of the linkage gear 6011 and the function gear 505, so that the protective plate 7 on the side of the driven auxiliary shaft 602 is switched to the vertical state for use, and then the top surfaces of the two protective plates 7 are mutually attached, the photovoltaic panel 8 is protected and
