[0002] Photovoltaic charging technology is a technology that uses the photovoltaic effect to convert solar energy into electrical energy and is used to charge batteries or other devices. Its principle is based on the photovoltaic effect, that is, when sunlight shines on the surface of photovoltaic materials (such as silicon), photons will excite electrons in the material, causing them to jump out of atoms to form current. This current can be used directly for charging, or converted through a certain circuit and stored in the battery;

Photovoltaic panels convert solar energy into electrical energy and store it in the corresponding energy storage structure. The size of the conversion area of ​​the photovoltaic panel during the conversion determines the corresponding electrical energy conversion efficiency to a large extent. The larger the photovoltaic panel, the more electrical energy it can convert under the same regulation. However, for some small and convenient energy storage vehicles, when the area of ​​the photovoltaic panel is large, it means that storage and transportation are extremely inconvenient, which greatly reduces the convenience of the entire device. Therefore, most of them can only use smaller photovoltaic panels to work, resulting in the problem of low overall electrical energy conversion efficiency in actual work.

[0033] Furthermore, the mounting platform is arranged on the mobile base, the fixed photovoltaic panel is mounted on the mounting platform, the two side-flip photovoltaic panels are rotatably mounted on both sides of the fixed photovoltaic panel, the two side-flip photovoltaic panels and the fixed photovoltaic panel are rotatably mounted with two folding photovoltaic panels, the buckling bracket is fixedly mounted on the mounting platform, and the supporting member is connected to the side-flip photovoltaic panel for limiting the side-flip photovoltaic panel.

[0034] Specifically, four corresponding rollers are arranged at the bottom of the mobile base to facilitate the movement of the entire vehicle body, the mounting platform is installed on the mobile base, and the mounting platform can be set as a lifting platform that can be adjusted in height according to actual conditions, and a corresponding energy storage mechanism is arranged in the mounting platform to facilitate the storage of electric energy converted by all photovoltaic panels, and a fixed photovoltaic panel is installed on the top of the mounting platform, and corresponding connecting bosses are arranged on both sides of the fixed photovoltaic panel, and two side-flip photovoltaic panels are installed on both sides of the fixed photovoltaic panel by matching with the connecting bosses on both sides of the fixed photovoltaic panel, and a corresponding inner groove is arranged at the bottom of the back side of the side-flip photovoltaic panel, and a corresponding overlapping horizontal column is arranged in the inner groove, and the overlapping horizontal column arranged on the side-flip photovoltaic panel matches the buckling bracket installed on the side of the mounting platform, and the clamping end of the buckling bracket and the overlapping horizontal column that cooperate with each other is made of elastic material, so that the side-flip photovoltaic panel after folding and storage can be limited by the buckling bracket;

[0035] The fixed photovoltaic panel and the side-flip photovoltaic panel are rotatably mounted with the corresponding folding photovoltaic panel, which can be unfolded and stored by rotation. When stored, the folding photovoltaic panel and the collection panel of the corresponding photovoltaic panel can be overlapped together, so that the collection panels of all photovoltaic panels will not be exposed after storage, thereby better protecting all photovoltaic panels. When working, the corresponding side-flip photovoltaic panel and the folding photovoltaic panel can be rotated to make the entire collection range wider, thereby improving the photoelectric collection efficiency of the entire device.

[0036] Furthermore, the rotating drum frame is rotatably installed at the bottom of each of the flip-over photovoltaic panels; the two piston columns are slidably installed on both sides of the rotating drum frame; the two socket seats are fixedly installed on both sides of the mounting platform; the connecting component is connected to the piston column to limit the piston column after storage; the one-way conductive component is connected to the rotating drum frame to control the movement of the piston column on the rotating drum frame; the ventilation component is connected to the rotating drum frame to assist the user in storing the piston column.

[0037] Furthermore, the two sides of the connecting slot shaft are respectively connected to the two piston columns; and the clamping frame is fixedly installed at the bottom of the flip-over photovoltaic panel.

[0038] When the present embodiment is in use, the rotating drum frame is provided with two connecting cylinders for correspondingly connecting to the piston columns, the entire rotating drum frame is a hollow structure, and corresponding through holes are provided on both sides of the rotating drum frame, and guide holes for cooperating with the piston columns are provided in the connecting cylinders of the rotating drum frame, and the two piston columns installed on each of the rotating drum frames are connected through the slot shaft, and the slot shaft is provided with an annular groove for cooperating with the clamping frame, and the cooperation between the slot shaft and the clamping frame is similar to the cooperation between the overlapping horizontal column at the bottom of the flip photovoltaic panel and the buckling bracket, and the corresponding frame is limited by an elastic clamping structure;

[0039] The socket seat is provided with a socket for cooperating with the piston column head. The user can extend and retract the piston column by sliding it on the rotating drum frame, and then complete the support of the corresponding flip photovoltaic panel by cooperating with the socket on the socket seat and the one-way conductive component, thereby ensuring the stability of the working state of the flip photovoltaic panels on both sides of the fixed photovoltaic panel.

[0040] Furthermore, the fixing plate is fixedly installed in the rotating drum frame; the sealing plug is slidably installed on the fixing plate; and both sides of the compression spring are respectively connected to the fixing plate and the sealing plug.

[0041] Furthermore, the threaded hole bracket is fixedly installed on the side of the rotating drum frame; the push-in screw is threadedly connected to the threaded hole bracket and passes through the threaded hole bracket.

[0042] When the present embodiment is in use, each outlet arranged on both sides of the rotating cylinder frame is installed with the fixing plate, and each fixing plate is slidably installed with the sealing plug plate, the outlet arranged on the rotating cylinder frame is a stepped circular hole, and the cylinder at the end of the sealing plug plate matches the small diameter circular hole of the outlet, and the compression spring is installed between the sealing plug plate and the fixing plate, and when normally not subject to any external force, the compression spring will drive the sealing plug plate to block the outlet, and when the user pulls the piston column to start to extend, the movement of the piston column causes negative pressure to be generated in the rotating cylinder, and then the external air pressure will squeeze the sealing plug plate, and then the corresponding outlet will be opened through the compression of the compression spring, so that the external airflow enters the rotating cylinder, thereby realizing the pulling out and extension of the piston column;

[0043] When the piston column is fully pulled out, the sealing plug plate will again seal the outlet provided on the rotating drum frame under the action of the compression spring. Since the outlets on both sides of the rotating drum frame are sealed by the corresponding sealing plug plates and the compression spring, the piston column cannot freely contract under the action of the internal air pressure of the rotating drum frame under normal circumstances, thereby ensuring the stability of the support for the designated flip photovoltaic panel.

[0044] The above structure allows the user to directly pull the connecting slot shaft to drive the two piston columns to cooperate with the corresponding socket seats when unfolding the support. After the piston columns and the socket seats are matched, the piston columns cannot be retracted, so they can maintain a stable support state, so that the corresponding flip photovoltaic panel can work stably.

[0045] The threaded hole bracket is provided on the outer sides of the two guide outlets of the rotating cylinder frame, and the threaded hole bracket is provided with a threaded hole that is compatible with the outer thread of the push screw. The push screw consists of a corresponding threaded rod and a knob. The user can turn the push screw to make the push screw move on the threaded hole bracket, and then push the cylinder blocked by the end of the sealing plug plate into the guide outlet of the rotating cylinder frame to achieve normal circulation of air between the inside of the rotating cylinder frame and the outside world. In this way, when the user needs to store the piston rod, the push screw can be turned, and then the sealing plug plate is driven to move by the push screw, so that the guide outlets on both sides of the rotating cylinder frame are in an open state, and then the corresponding piston rods are stored.

[0046] Preferably, the extension assembly provided by the present invention further comprises a clamping frame, a sliding bracket, a return spring and a clamping member, and the clamping member comprises a downward moving frame and a compression spring.

[0047] Furthermore, the two foldable photovoltaic panels on the side-flip photovoltaic panel are respectively installed with the clamping frame and the sliding bracket, and the two foldable photovoltaic panels on the fixed photovoltaic panel are also respectively installed with the clamping frame and the sliding bracket; the sliding bracket and the corresponding sliding grooves of the foldable photovoltaic panel are provided with a plurality of return springs; each sliding bracket is installed with the clamping component to facilitate limiting the sliding bracket.

[0048] Furthermore, the lower moving frame is slidably mounted on each of the sliding brackets; and a plurality of the extrusion springs are arranged at the position where the lower moving frame cooperates with the sliding bracket.

[0049] When the present embodiment is in use, the two flip-over photovoltaic panels installed on the same photovoltaic panel are respectively provided with the clamping frame and the sliding frame, the sliding frame cooperates with the corresponding sliding groove provided at the bottom of the flip-over photovoltaic panel through the sliding boss provided at the bottom, the sliding frame and the sliding groove that cooperate with the corresponding flip-over photovoltaic panel are provided with the return spring, and at the same time, the corresponding lower moving frame is slidably installed on each sliding frame, and the extrusion spring is also provided in the guide groove that cooperates with the corresponding sliding frame;

[0050] When the two side-turning photovoltaic panels are folded and stored, the sliding bracket will contract by sliding on the corresponding side-turning photovoltaic panel to squeeze the return spring and cooperate with the clamping bracket set on the designated side-turning photovoltaic panel, and then the squeezing spring will drive the lower moving bracket to cooperate with the sliding groove used for the sliding bracket to slide, so that the sliding bracket and the clamping bracket maintain a corresponding cooperation state. After the sliding bracket and the clamping bracket complete the cooperation, the corresponding two side-turning photovoltaic panels cannot be turned over normally.

[0051] When the user needs to flip and open the two side-flip photovoltaic panels after folding and storage, he needs to buckle the lower moving frame on the sliding bracket first to make the lower moving frame move up. When the lower moving frame moves to a height that matches the corresponding side-flip photovoltaic panel slide slot, the sliding bracket will move and reset under the action of the reset spring. After the sliding bracket is reset, the side-flip photovoltaic panels on both sides can be flipped and opened normally. After the sliding bracket is reset, the extrusion spring will be in a compressed state. When the two side-flip photovoltaic panels are flipped and stored next time, the user will move the sliding bracket to move. After the sliding bracket moves to the specified position, the lower moving frame will once again cooperate with the corresponding slide slot through the extrusion of the extrusion spring, thereby limiting the sliding bracket.
