The area of the solar panel directly determines the power generation of the power generation vehicle. The application of the stacked and unfolded solar panels can install larger area solar panels on the small vehicle. It has become a common phenomenon that one vehicle installs three panels, four panels or even more number of solar panels.

[0003] At present, the solar panel unfolding method of the solar power generation vehicle is already mature. The heavy-duty slide rail of industrial grade is adopted. Most of them adopt three rail structure, which is composed of outer fixed rail, middle fixed rail, inner fixed rail, steel ball and retainer. The steel ball is placed in the retainer and is lubricated with yellow oil. However, such structure has great limitations in use. First of all, the steel ball and the retainer are open type, the yellow oil is not sealed, and the consumption is very fast, which is not convenient to maintain. Secondly, when used in harsh environment such as wind and sand, the sand will stick to the yellow oil, which will increase the wear and tear of the steel ball and block the movement of the steel ball, affecting the normal work of the slide rail. Thirdly, the installation precision between the slide rails is very high, otherwise the three rail tracks will be out of position, the steel ball will be clamped, the unfolding resistance of the slide rail will be too large, and the slide rail cannot work. In addition, the specifications of the solar panel after unfolding or folding are usually fixed, which is difficult to adapt to vehicles with different widths or lengths, which makes the expandability of the solar panel unfolding mechanism not strong.

A solar powered vehicle, characterized by, The utility model relates to a solar panel unfolding mechanism, comprising: a frame, including two opposite slide rail boxes and two opposite mounting racks for mounting a first solar panel, the two mounting racks are arranged between the two slide rail boxes, and the ends of the two mounting racks are connected to the ends of the two slide rail boxes respectively, and each of the two slide rail boxes is provided with a sliding groove; two fixed roller sets, each of which includes two first rollers arranged opposite to the ends of the slide rail boxes and spaced apart by a certain distance; two slide rail sets for mounting a second solar panel, which are arranged in the sliding grooves and can slide back and forth in the sliding grooves, and the ends of the slide rail sets close to the fixed roller sets can extend out of the distance and drive the second solar panel to extend out from below the first solar panel. The end of one of the slide rail boxes close to the fixed roller set is provided with a latch, and the slide rail set is provided with a limiting hole for the insertion of the latch. A plurality of limiting holes are arranged at intervals on the slide rail set, and the length of the second solar panel extending out from below the first solar panel can be controlled by inserting the latch into different limiting holes. The slide rail set includes a movable track bar and connecting plates connected to both sides of the movable track bar; The connecting plates inside the two slide rail sets are connected to the opposite sides of the second solar panel respectively; The movable track bar is arranged in the distance and can slide back and forth in it. The slide rail set also includes a movable roller set, which includes two second rollers arranged opposite to the ends of the connecting plates away from the fixed roller set, and the two second rollers are also spaced apart by the distance. Fixed track bars are arranged opposite to each other on the top and bottom of the slide rail box to form a track for the movable roller set to slide back and forth in the sliding groove. The connecting plates inside the two slide rail sets are provided with opposite mounting pieces, and the opposite sides of the second solar panel are detachably connected to the mounting pieces by screws. Bearings are fixed in the first rollers and the second rollers; and The first rollers and the second rollers have recesses recessed inward and matched with the movable track bar and the fixed track bar on their wheel diameters. The bottoms of the two slide rail boxes are each provided with a plurality of through holes.
