[0040] The telescopic rod 5 is preferably provided with a transverse through hole on its outer side. When the telescopic rod 5 is pulled to the maximum, a metal rod is inserted into the through hole to form a snap connection with the top of the top cover 6, so that the telescopic rod 5 is always in a pulled state, thereby ensuring the continuous expansion of the first photovoltaic panel 3 and the second photovoltaic panel 7, and the switching of the connection state between the energy storage battery 18 and the charging rail.

[0041] Specifically, the lifting assembly includes a lifting slider 16 and a folding rod 13. The lifting slider 16 is equidistantly arranged on the outside of the telescopic rod 5.

At this time, the pulling wire 14 pulls the I-shaped slider 24, and the I-shaped slider 24 moves outward along the inner wall of the T-shaped slot 23. At this time, the spring sleeved on the outside of the metal rod is stretched. Since the I-shaped slider 24 is fixedly connected to the first photovoltaic panel 3, the first photovoltaic panel 3 moves outward relative to the guide rail 15, thereby achieving the expansion of the first photovoltaic panel 3.

[0046] When the telescopic rod 5 is retracted downward, the pulling wire 14 and the I-shaped slider 24 are reset to the initial position under the elastic potential energy of the spring. At this time, the first photovoltaic panel 3 is reset to the inner side of the storage groove 8 and engages with the movable hole inside the storage groove 8, wherein the movable shaft connected to the first photovoltaic panel 3 is set to an open state, see the attached Fig.13As the telescopic rod 5 contracts, the first photovoltaic panel 3 and the second photovoltaic panel 7 gather inwardly under the action of the lifting slider 16 and the folding rod 13.

When the energy storage battery 18 is placed inside the battery box 10, due to the effect of gravity, the support plate 11 will drive the limit slider 21 and the return spring 22 to move downward, thereby misaligning the access port 2 of the battery box 10 to ensure that the battery box 10 will not detach from the inside of the energy storage box 1, wherein the limit slider 21 passes through the square hole 17 and is connected to the spring column 19.
