[0037] Further, in other preferred embodiments of the present invention, the slide bar set 30 includes a movable track bar 310 and a connecting plate 320 connected to both sides of the movable track bar 310;

[0038] The connecting plates 320 located inside the two slide bar groups 30 are respectively connected to two opposite sides of the second solar panel 50;

[0039] The movable track rod 310 is strung within the spacing and can slide reciprocally therein.

[0040] Specifically, the movable track rod 310 and the two connecting plates 320 are stacked in a sandwich-like manner along their length direction, and the movable track rod 310 is located between the two connecting plates 320, which are connected by screws or the like; the opposite sides of the second solar panel 50 are connected to the connecting plates 320 located on the inner sides of the two slide bar groups 30 by screws or the like, so as to carry the second solar panel 50 between the two slide bar groups 30; the diameter of the movable track rod 310 is slightly smaller than the size of the spacing, so that the movable track rod 310 can be arranged in series within the spacing, and the rolling of the two first rollers 210 enables the movable track rod 310 to slide back and forth in the slide bar box 110.

[0041] Furthermore, in other preferred embodiments of the present invention, a relative mounting plate 330 is provided on the connecting plate 320 located on the inner side of the two slide rod groups 30, and the opposite sides of the second solar panel 50 are detachably connected to the mounting plate 330 by screws.

[0042] Specifically, the two slide bar groups 30 have a total of four connecting plates 320, and the two inner connecting plates 320 are each provided with the mounting plates 330, so that the mounting plates 330 are arranged relative to each other, and the opposite sides of the second solar panel 50 are detachably connected to the mounting plates 330 by connecting structures such as screws, so as to carry the second solar panel 50 between the two slide bar groups 30.

[0043] Furthermore, in other preferred embodiments of the present invention, the slide bar group 30 also includes a movable roller group 340, and the movable roller group 340 includes two second rollers 3401. The two second rollers 3401 are relatively arranged at one end of the connecting plate 320 away from the fixed roller group 20, and the two second rollers 3401 are also separated by the spacing.

[0044] Specifically, the fixed roller group 20 is arranged at one end of the slide box 110, and the movable roller group 340 is arranged at the other end opposite to the slide box 110, but the difference between the two is that the fixed roller group 20 is fixed relative to the slide box 110, while the movable roller group 340 is movable relative to the slide box 110, that is, the movable roller group 340 can reciprocate in the slide box 110, and the movable roller group 340 here includes two second rollers 3401, and the two second rollers 3401 are relatively arranged at one end of the connecting plate 320 away from the fixed roller group 20, that is, the two second rollers 3401 can follow the slide group 30 to slide reciprocally in the slide box 110, and the two second rollers 3401 are also separated by the distance like the two first rollers 210.

[0045] In addition, in other preferred embodiments of the present invention, fixed track bars 1101 are respectively disposed on the top and bottom of the slide box 110 to form a track in the slide groove 130 for the movable roller group 340 to slide back and forth.

[0046] Specifically, the two fixed track rods 1101 are respectively fixedly connected to the top and bottom of the slide box 110, and the specific connection method includes but is not limited to screws or an integrated connection. The two fixed track rods 1101 can make the two second rollers 3401 slide back and forth more smoothly in the slide box 110, that is, the two fixed track rods 1101 can form a track in the slide groove 130 for the movable roller group 340 (two second rollers 3401) to slide back and forth.

[0047] Furthermore, in other preferred embodiments of the present invention, bearings 60 are fixed inside both the first roller 210 and the second roller 3401 .

[0048] Specifically, the bearing 60 is embedded in the first roller 210 and the second roller 3401. The setting of the bearing 60 can make the first roller 210 and the second roller 3401 roll more smoothly, thereby reducing friction resistance and making the second solar panel 50 slide in and out more smoothly.

[0049] Furthermore, bearing covers (not shown in the figure) are provided on both sides of the bearing 60 to shield the balls of the bearing 60 and prevent them from being disturbed by wind, sand, dust, etc., so as to extend their service life.

[0050] In addition, in other preferred embodiments of the present invention, the wheel diameters of the first roller 210 and the second roller 3401 are provided with grooves 3402 that are recessed inwards and match the movable track rod 310 and the fixed track rod 1101 .

[0051] Specifically, the surfaces of the first roller 210 and the second roller 3401 are not flat, but have the groove 3402 that is recessed inward, that is, the first roller 210 and the second roller 3401 are recessed inward along their wheel diameters to form the groove 3402. Here, the groove 3402 is preferably capable of at least partially accommodating the movable track rod 310 and the fixed track rod 1101, that is, the diameter of the movable track rod 310 and the diameter of the fixed track rod 1101 match the depth of the groove 3402. Here, by providing the groove 3402, the contact area between the movable track rod 310 and the fixed track rod 1101 and the first and second rollers can be enlarged, and a slideway is provided for their relative sliding, thereby making the sliding in and out of the second solar panel 50 smoother.

[0052] In addition, in other preferred embodiments of the present invention, a plurality of through holes 1102 are disposed at the bottom of the two slide boxes 110 .

[0053] Here, the product of the embodiment of the present invention is an outdoor product and is placed in a harsh environment with strong wind and sand. It is inevitable that mud and sand will enter the slide box 110. By setting a plurality of through holes 1102 at the bottom of the two slide boxes 110, the mud and sand can be discharged, ensuring the cleanliness of the slide 130, thereby making the second solar panel 50 slide in and out more smoothly.

[0054] Furthermore, a support frame 1103 is provided on the slide box 110, and the support frame 1103 is arranged on the side of the second solar panel 50 away from the first solar panel 40. The support frame 1103 includes but is not limited to a frame structure in which horizontal supports and vertical supports are staggered with each other. On the one hand, it can enhance the strength of the solar panel unfolding structure, and on the other hand, it can also be used to connect with an external structure (such as a solar car).

[0055] Furthermore, in other preferred embodiments of the present invention, a latch lock 70 is provided at the end of the slide bar box 110 close to the fixed roller assembly 20, and a limiting hole 3101 for inserting the latch lock 70 is provided on the slide bar assembly 30.

[0056] Specifically, the latch lock 70 is provided on one of the two slide boxes 110, and the latch lock 70 is arranged on the end close to the fixed roller group 20, and has a latch that can reciprocate, and the slide bar group 30 is also provided with a limiting hole 3101 for the latch of the latch lock 70 to be inserted; here, the limiting hole 3101 is provided on the movable track rod 310, which can be a through hole passing through the movable track rod 310, or a blind hole with an opening facing the insertion direction of the latch; when in use, the latch of the latch lock 70 slides toward the slide bar group 30 and is inserted into the limiting hole 3101, so as to lock the slide bar group 30 so that it cannot slide relative to the slide bar box 110, thereby adjusting the sliding position of the second solar panel 50 For fixing; specifically, when the second solar panel 50 completely slides to the bottom of the first solar panel 40, the pin of the pin lock 70 is inserted into the limit hole 3101 to lock the two, forming a stacked trend of upper and lower locking, which can be used for packaging, transportation, etc., to avoid relative sliding of the second solar panel 50 and the first solar panel 40, thereby improving the safety during packaging and transportation; it can also be that when the second solar panel 50 slides outside the first solar panel 40, the pin of the pin lock 70 is inserted into the limit hole 3101 to lock the two, forming an upper and lower layer unfolding each other, which can be used for light-receiving power generation, to avoid relative sliding of the second solar panel 50 and the first solar panel 40, thereby affecting the power generation efficiency.

[0057] Furthermore, in other preferred embodiments of the present invention, a plurality of limiting holes 3101 are provided at intervals on the slide rod group 30, and the length of the second solar panel 50 extending from under the first solar panel 40 can be controlled by inserting the latch lock 70 into different limiting holes 3101.

Figure 3As shown, five limiting holes 3101 are provided at intervals above the movable track rod 310. The number of the limiting holes 3101 is not limited here and can be set according to the specific specifications of the solar panel unfolding mechanism. By inserting the pin of the latch lock 70 into the limiting holes 3101 at different positions, the length of the second solar panel 50 extending out of the first solar panel 40 can be controlled, that is, the overall light receiving area of ​​the solar panel is changed, that is, the overall power generation power of the solar panel is adjusted; in addition, by inserting the pin of the latch lock 70 into the limiting holes 3101 at different positions, the length of the second solar panel 50 extending out of the first solar panel 40 can be controlled, that is, the overall length or width of the solar panel is changed, as shown in FIG. Fig. 6A , Figure 6B as well as Figure 6C As shown, by controlling the length of the second solar panel 50 extending out of the first solar panel 40, three different lengths of the solar panel unfolding structure are displayed respectively, so that it can be matched with vehicles of different specifications (length or width), realizing the vision of it as a universal product, and thus effectively improving the application scope of the solar panel unfolding mechanism.
