The rotating shaft 407 can rotate under the action of the motor 406, thereby driving the first gear 408 to rotate.

[0034] In this embodiment, Figure 2 , Figure 3 , Figure 5 and Figure 8 As shown, a first groove 409 is opened in the ceiling 402, and the bottom of the first groove 409 is rotatably connected to the second gear 410, the second gear 410 is meshingly connected to one side of the first gear 408, and an extrusion ring 411 is fixed to the upper end surface of the second gear 410.

The second compression spring 429 supports the fourth piston 430. When the third piston 426 starts to move upward, part of the hydraulic oil will be pressed into the second groove 428. After unlocking the moving frame 435, the fourth piston 430 will automatically pop up.

[0039] In this embodiment, Figure 2 , Figure 3 , Fig.10 and Fig.11As shown, an oil storage channel 432 is provided in the ceiling 402, and the oil storage channel 432 is connected to the third oil groove 427 through the second connecting channel 431, a fifth piston 433 is slidably connected in the oil storage channel 432, and a moving plate 434 is fixed to the outer side of the fifth piston 433, the moving plate 434 passes through the oil storage channel 432 and is connected to the moving frame 435, and three card slots 436 are provided at the bottom of the moving frame 435, the locking block 422 is engaged in one of the card slots 436, and a second solar cell panel 437 is fixed to the inner side of the moving frame 435.

The first piston 417 moves upward, and the second oil groove 420 stores hydraulic oil. The second piston 421 moves downward, and the lock block 422 moves downward and leaves the card groove 436, thereby unlocking the moving frame 435. At the same time, the first chain transmission assembly 423 drives the second chain transmission assembly 424 to operate, and the four screw rods 425 rotate. The third piston 426 moves upward, and the third oil groove 427 stores hydraulic oil. When the third piston 426 starts to move upward, the fourth piston 430 moves downward to pump the hydraulic oil into the second groove 428. After unlocking the moving frame 435, the fourth piston 430 automatically When the third piston 426 continues to move upward, the fifth piston 433, the movable plate 434 and the movable frame 435 move as a whole, so as to unfold and use the second solar cell panel 437.
