Solar photovoltaic panels are the core part of solar power generation systems and are currently the most common devices for converting solar energy.

[0055] The working principle of this solar photovoltaic panel is as follows:

[0056] like Figure 1The telescopic frame 3 of the present invention is shown in a lowered state, and the photovoltaic panel mechanism 4 is in a retracted state. When the present invention needs to be unfolded, the drive motor 21 is started to drive the worm 22 to rotate. The rotation of the worm 22 drives the meshing worm wheel 23 to rotate, and then drives the first connecting shaft 311 to rotate. Since the first connecting shaft 311 and the two first connecting rods 32 are fixedly connected; the second connecting shaft 312 and the two second connecting rods 33 are rotatably matched, and the sliding shaft pin 371 is slidably set in the first sliding groove 321 and the second sliding groove 331, so that the rotation of the first connecting rod 32 drives the second connecting rod 33 to rotate and rise around the second connecting shaft 312. Since one end of the fourth link 35 is hinged on the first link 32, and the other end is hinged on the second link 33, one end of the fifth link 36 is hinged on the second link 33, and the other end is hinged on the third link 34, the third link 34 is hinged on the first link 32, and then when the first link 32 and the second link 33 rotate and rise, the fifth link 36 is driven to rise, and the photovoltaic panel mechanism 4 is driven to rise and tilt at a certain angle. As the telescopic frame 3 rises, when the sliding shaft pin 371 comes to one end of the second slide groove 331, the telescopic frame 3 is limited, and the telescopic frame 3 is in a raised state. Since the arc rod 38 is fixedly set on the third link 34, the protection pin shaft 412 is slidably set in the arc groove 381, the protection pin shaft 412 is slidably set in the first special rod groove 471, and the special-shaped link 47 is rotatably set on the middle plate shaft 423, during the lifting process of the lifting frame 3, the arc rod 38 is driven to follow the rotation of the third link 34, and then the protection cover 41 is driven to move upward along the upper track 421. At the same time The special-shaped connecting rod 47 is driven to rotate accordingly. Since the lower plate shaft pin 432 slides in the second special-shaped rod groove 472, the lower plate 43 is driven to slide downward along the lower track 423. Since the side plate 46 is slidably set in the middle plate 42, the side plate shaft pin 461 is slidably set in the middle plate horizontal groove 424, and the lower plate linkage pin 436 is slidably set in the middle plate vertical groove 425, one end of the linkage rod 49 is hinged on the side plate shaft pin 461, and the other end is hinged on the lower plate linkage pin 436, so that when the lower plate 43 moves downward along the lower track 423, the side plate 46 is driven to extend forward.When the protective cover 41 and the lower plate 43 slide and unfold, the first flip plate 441 and the fourth flip plate 444 are no longer blocked by the second limiting plate 428, and the second flip plate 442 and the third flip plate 443 are no longer blocked by the first limiting plate 427. Since the protection long axis pin 4131 slides along the first limiting groove 4411, the protection short axis pin 4141 slides along the second limiting groove 4421, the lower plate long axis pin 4331 slides along the third limiting groove 4431, and the lower plate short axis pin 4341 slides along the fourth limiting groove 4441, the first flip plate 441 is rotatably connected to the protection long axis 413, the second flip plate 442 is rotatably connected to the protection short axis 414, and the third flip plate 443 is rotatably connected to the lower plate long axis 43 The fourth flip plate 444 is rotatably connected to the lower plate short shaft 434, so that under the action of the first torsion spring 481, the second torsion spring 482, the third torsion spring 483, and the fourth torsion spring 484, the first flip plate 441, the second flip plate 442, the third flip plate 443, and the fourth flip plate 444 are driven to flip outward 90 degrees. When the flipping is completed, the first extending plate 451 and the second extending plate 452 are no longer limited by the protective baffle 415, and the third extending plate 453 and the fourth extending plate 454 are no longer limited by the lower plate baffle 435, and are extended under the action of the first rotating plate spring 4414, the second rotating plate spring 4424, the third rotating plate spring 4434, and the fourth rotating plate spring 4444. All photovoltaic panels installed on the middle panel mounting surface 426, the lower panel mounting surface 437, the first rotating panel mounting surface 4413, the second rotating panel mounting surface 4423, the third rotating panel mounting surface 4433, the fourth rotating panel mounting surface 4443, the first extending panel mounting surface 4512, the second extending panel mounting surface 4522, the third extending panel mounting surface 4532, the fourth extending panel mounting surface 4542 and the side panel mounting surface 462 of the present invention are fully unfolded (such as). Figure 3 As shown), the photovoltaic panel mechanism 4 is in an unfolded state, completing the full unfolding of the present invention.

[0057] When the present invention needs to be folded, the start motor 21 is reversed, driving the first connecting rod 32 and the second connecting rod 33 to reverse and descend, and the third connecting rod 34, the fourth connecting rod 35 and the fifth connecting rod 36 cooperate to switch the telescopic frame 3 to the lowered state. During the retraction process of the telescopic frame 3, the arc rod 38 is driven to move by the third connecting rod 34, and the protective cover 41 is driven to slide into the middle plate 42 through the arc groove 381, driving the special-shaped connecting rod 47 to rotate, and at the same time, the lower plate 43 is driven to slide into the middle plate 42 through the special-shaped connecting rod 47. During the retraction process of the protective cover 41 and the lower plate 43, the first flip plate 441, the fourth flip plate 444 and the second limit plate 428 touch, and the second flip plate 442, the third flip plate 443 and the first limit plate 427 touch, thereby pushing The first flip plate 441, the second flip plate 442, the third flip plate 443 and the fourth flip plate 444 are moved to overcome the rotation of the first torsion spring 481, the second torsion spring 482, the third torsion spring 483 and the fourth torsion spring 484 respectively, so that the first flip plate 441, the second flip plate 442, the third flip plate 443 and the fourth flip plate 444 rotate, shrink and reset. At the same time, in the process of retraction, the first extending plate 451 and the second extending plate 452 are in contact with the protective baffle 415, and the third extending plate 453 and the fourth extending plate 454 are in contact with the lower plate baffle 435, respectively overcoming the contraction of the first rotating plate spring 4414, the second rotating plate spring 4424, the third rotating plate spring 4434 and the fourth rotating plate spring 4444, and the photovoltaic panel mechanism 4 switches to the contracted state.

[0058] When the telescopic frame 3 is switched to the lowered state, the photovoltaic panel mechanism 4 is completely retracted (such as Figure 2 All photovoltaic panels installed on the middle plate mounting surface 426, the lower plate mounting surface 437, the first rotating plate mounting surface 4413, the second rotating plate mounting surface 4423, the third rotating plate mounting surface 4433, the fourth rotating plate mounting surface 4443, the first extending plate mounting surface 4512, the second extending plate mounting surface 4522, the third extending plate mounting surface 4532, the fourth extending plate mounting surface 4542 and the side plate mounting surface 462 are all retracted and shielded, thereby playing a protective role.
