In this embodiment, as shown in Figures 1 to 3, the embodiment of the present application provides a photovoltaic wing-spreading box-type mobile light-storage direct-flexible super charging station, the charging station includes a container body 20, a support assembly arranged on the container body 20, a walking device 30 arranged at the lower end of the container body 20, and a plurality of charging piles 23, a battery energy storage system 25 and a bidirectional power converter 26 arranged in the container body 20; a plurality of solar panels 10 are arranged on the support assembly; the container body 20 includes a bottom plate 21, and support plates 22 arranged at both ends of the bottom plate 21; the charging piles 23, the battery energy storage system 25 and the bidirectional power converter 26 are all assembled on the bottom plate 21; when the support assembly drives the plurality of solar panels 10 to the top of the container body 20, the The charging station is in a power storage working state; when the support assembly drives the multiple solar panels 10 to be placed in a vertical direction, the solar panels 10 serve as side wall panels of the container body 20 and are combined with the bottom plate 21 and the support plate 22 to form the outer box structure of the container body 20; the input end of the bidirectional power converter 26 is electrically connected to the mains, and the output end of the bidirectional power converter 26 is electrically connected to the first input end of the battery energy storage system 25; the output end of the solar panel 10 is electrically connected to the second input end of the battery energy storage system 25, and the output end of the battery energy storage system 25 is electrically connected to the charging pile 23, and the bidirectional power converter 26 receives direct current from the first input end and the second input end and outputs the direct current to the charging pile 23.

The container body 20 is used to accommodate the main functional components, and the support assembly can support the solar panel 10 upward and generate solar power. When the solar panel 10 is not needed, the solar panel 10 can be adjusted to a vertical direction through the support assembly, so that the solar panel 10 is combined with the bottom plate 21 and the support plate 22 as a side wall plate to form the outer box structure of the container body 20, which is convenient for centralized storage of the solar panel 10, the charging pile 23, the battery energy storage system 25, and the bidirectional power converter 26, realizing the intensive storage of various components; thus, the charging station can be configured for use or stored conveniently and quickly, greatly saving the area occupied by the charging station during use.

The liquid circulating in the serpentine pipe cools the liquid therein by exchanging heat with the outside world, and the cooled liquid circulates again to the side of the heating component for circulating heat dissipation.

In a more specific embodiment, a box side door 24 that can be opened and closed is provided on the support plate 22 at one end. The box side door 24 can also be provided on the support plate 22 at one end, and the specific setting structure is shown in FIG5 , so that the user can enter the container charging station through the box side door 24, thereby facilitating the maintenance and repair of the container charging station.

In a more specific embodiment, the charging pile 23, the battery energy storage system 25 and the bidirectional power converter 26 can be installed on the central axis parallel to the long side direction on the bottom plate 21, and the support components and solar panels 10 arranged on both sides of the container body 20 can be deployed or stored from both sides of the container body 20, which will not affect the charging pile 23, battery energy storage system 25 and bidirectional power converter 26 configured near the central axis, further improving the intensive storage capacity of various components in the container body 20, and realizing rapid deployment and rapid storage.

In a more specific embodiment, as shown in FIG. 4 to FIG. 5 , the support assembly includes a top plate 1 and two cover plates 2 movably connected to the top plate 1 ; both ends of the top plate 1 are fixedly connected to the two support plates 22 , respectively.

A cover plate 2 is provided on both sides of the long axis direction of the top plate 1, and the cover plates 2 are rotatably connected to the top plate 1. The lifting mechanism 6 lifts the cover plate 2 or uses the gravity of the cover plate 2 as a driving force to rotate the cover plate 2 along its side, that is, the long side connected between the cover plate 2 and the top plate 1 is the rotation axis 7. The cover plate 2 can be quickly flipped by the driving of the lifting mechanism 6, so as to realize the rapid deployment or intensive storage of the solar panel 10. The solar panel 10 is fixedly set on the fixing rod 5, and the long axis direction of the fixing rod 5 can be adjusted by rotating the support rod 4, thereby adjusting the pitch angle of the solar panel 10 set on the fixing rod 5. Thereby, the solar panel 10 can be directed to the direction of sunlight, and the power generation efficiency of the solar panel 10 per unit area is improved. The tilt position of the solar panel 10 after adjustment during the specific application process is shown in Figures 6 and 7.

In a more specific embodiment, the cross section of the support rod 4 is rectangular.

The rotating shafts 7 at both ends of the support rod 4 are respectively connected to a rotating motor 71 for transmission.

As shown in FIG5 , by setting the cross-section of the support rod 4 to be rectangular, the fixed rod 5 can be prevented from rotating relative to the support rod 4 during the process of adjusting the angle of the fixed rod 5, that is, the fixed rod 5 can be more firmly fixed to the support rod 4, so that the inclination angle of the fixed rod 5 can be more accurately adjusted when the support rod 4 is driven to rotate, that is, the pitch angle of the solar panel 10 can be more accurately adjusted, thereby further improving the power generation efficiency of the solar panel 10 per unit area.

In order to further improve the rotation stability of the support rod 4, a rotating motor 71 that is transmission-connected to the rotating shaft 7 can be respectively arranged on the rotating shaft 7 at both ends of the support rod 4.

The curling edge can be used to protect the solar panel 10. When the solar panel 10 is stored, the side edge of the solar panel 10 abuts against the inner side of the curling edge, thereby preventing the side edge of the solar panel 10 from being damaged by being bumped.

A connecting seat 62 can also be set on the side of the curling edge, and a connecting shaft 63 is set in the connecting seat 62. The end of the lifting rod 64 in the lifting cylinder 61 is rotatably connected to the connecting shaft 63.
