TECHNICAL FIELD

[0002] Photovoltaic charging technology is a technology that converts solar energy into electrical energy using the photovoltaic effect and uses it 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 the atom to form an electric current. This current can be directly used for charging, or stored in a battery after being converted by a certain circuit.

[0003] In natural disasters (such as earthquakes, floods, typhoons, etc.) or emergencies, power supply may be interrupted, and the existing mobile energy storage vehicle capable of photovoltaic charging can provide emergency power support to provide power for rescue equipment, communication equipment, lighting equipment, etc. to ensure the smooth progress of rescue work.

The photovoltaic panel converts solar energy into electrical energy and stores it in the corresponding energy storage structure. The size of the conversion area of the photovoltaic panel greatly determines the corresponding electrical energy conversion efficiency. The larger the photovoltaic panel, the more electrical energy it can convert under the same adjustment. However, for some small and convenient energy storage vehicles, a larger photovoltaic panel means that it is not convenient to store and transport, greatly reducing the convenience of the entire device.

[0035] The fixed photovoltaic panel and the side-turning photovoltaic panel are both provided with corresponding folding photovoltaic panels, which can be unfolded and stored by rotating, and the collecting panels of the folding photovoltaic panels and the corresponding photovoltaic panels can be overlapped when stored, so that the collecting panels of all photovoltaic panels are not exposed after storage, thereby better protecting all photovoltaic panels, and when working, the corresponding side-turning photovoltaic panels and folding photovoltaic panels can be rotated to make the whole collecting range wider, thereby improving the photoelectric collection efficiency of the whole device.

[0046] Preferably, the stretching assembly further comprises a clamping frame, a sliding bracket, a reset spring and a clamping member, the clamping member comprising a downward frame and a pressing spring.

[0047] Further, the two folding photovoltaic panels on the side folding photovoltaic panel are respectively provided with the clamping frame and the sliding bracket, and the two folding photovoltaic panels on the fixed photovoltaic panel are also respectively provided with the clamping frame and the sliding bracket; the sliding bracket and the sliding groove corresponding to the folding photovoltaic panel are provided with a plurality of reset springs; the clamping member is installed on each sliding bracket to limit the sliding bracket.

[0050] In the state of folding and storing the two side folding photovoltaic panels, the sliding bracket cooperates with the clamping frame provided on the corresponding side folding photovoltaic panel by sliding and pressing the reset spring to shrink, and then the downward frame cooperates with the sliding groove for the sliding bracket to slide by the pressing spring, so that the sliding bracket and the clamping frame keep corresponding cooperation, and the two side folding photovoltaic panels cannot be normally turned over after the sliding bracket and the clamping frame are completely cooperated.

[0051] When the user needs to open the two folded side-folding photovoltaic panels, the lower moving frame buckle on the sliding support needs to be buckled first, so that the lower moving frame moves up. When the lower moving frame moves to a height corresponding to the disengagement of the sliding groove of the side-folding photovoltaic panel, the sliding support will move and reset under the action of the reset spring. After the sliding support is reset, the two side-folding photovoltaic panels on both sides can be normally flipped open. After the sliding support is reset, the compression spring will be in a compressed state. When the two side-folding photovoltaic panels are flipped and stored next time, the user will move the sliding support. After the sliding support moves to the specified position, the lower moving frame will be matched with the corresponding sliding groove again through the extrusion of the compression spring, so as to limit the sliding support.
