[0055] When the photovoltaic component 1 is in the unfolded state, the third assembly plate 301 and the fourth assembly plate 305 are both arranged horizontally, and the right end of the third assembly plate 301 is rotatably connected to the first photovoltaic panel 101 through the third fixed shaft 302, and the left end of the third assembly plate 301 is rotatably connected to the second photovoltaic panel 102 through the fourth fixed shaft 303.

[0056] Furthermore, when the photovoltaic module 1 switches from the unfolded state to the folded state, before flipping the third photovoltaic panel 103 until the illuminated surface of the third photovoltaic panel 103 is in contact with the back surface of the first photovoltaic panel 101, the fourth assembly plate 305 is removed, and the fourth fixed axis 303 loses its limit on the second strip hole 304, then the third photovoltaic panel 103 is pulled to the right so that the fourth fixed axis 303 is located at the left end of the strip hole, and at this time a gap appears between the left side of the third photovoltaic panel 103 and the right side of the second photovoltaic panel 102, then the third photovoltaic panel 103 can be flipped freely.

[0057] like Figure 8 As shown, in one embodiment of the present invention, the support frame 6 includes: a fixed beam 7 and two struts 601, wherein the bottom surface of the fixed beam 7 is provided with an assembly slot 701, the assembly slot 701 is in a strip shape as a whole, and the assembly slot 701 extends to the two end surfaces of the fixed beam 7 along the length direction of the fixed beam 7. Further, the assembly slot 701 is rotatably connected to the upper ends of the two struts 601, and the lower ends of the two struts 601 are slidably connected to the support rail 5. By adjusting the spacing between the lower ends of the two struts 601, that is, adjusting the angle between the two struts 601, the total height of the support frame 6 can be accurately adjusted so that the support frame 6 can stably support the photovoltaic module 1 to a certain height. Preferably, the middle parts of the two struts 601 are connected by a fixed rod 602 to form a triangular support structure to form a stable support for the photovoltaic module 1. Specifically, the left end of the fixed rod 602 is connected to a strut 601, and the right end of the fixed rod 602 is connected to another strut 601.

[0058] It should be noted that a first connecting hole is set in the middle part of one of the support rods 601, and a plurality of second connecting holes are set on the other support rod 601, and the plurality of second connecting holes are equidistantly arranged along the length direction of the support rod 601. The left end of the fixing rod 602 is connected to the first connecting hole on one of the support rods 601 through a first positioning pin, and the right end of the fixing rod 602 is connected to the second connecting holes at different positions through a second positioning pin as needed, so that the distance between the lower ends of the two support rods 601 can be adjusted, that is, the angle between the two support rods 601 can be adjusted, and then the height of the overall support frame 6 can be flexibly adjusted.

[0059] like Fig.12As shown, in one embodiment of the present invention, assembly grooves 702 are set at both ends of the fixed beam 7. Specifically, the width of the assembly groove 702 is equal to the width of the support rod 601 to ensure that the support rod 601 can be snapped into the assembly groove 702. When the photovoltaic component 1 needs to be stored, the photovoltaic component 1 is folded, and then the fixed rod 602 connected to the support rod 601 is removed, and the distance between the lower ends of the two support rods 601 is adjusted. The angle between the two support rods 601 gradually increases, and the fixed beam 7 descends until its bottom surface abuts against the top surface of the bracket guide rail 5, completing the folding of the support frame 6.

[0060] It should be noted that when the bottom surface of the fixed beam 7 abuts against the top surface of the bracket guide rail 5, the support rod 601 is snapped into the assembly groove 702, and the two side surfaces of the assembly groove 702 abut against the two side surfaces of the support rod 601, forming a certain limit for the support rod 601, which can prevent the support rod 601 and the fixed beam 7 from moving, and improve the stability of the overall mobile photovoltaic power supply during transportation. In addition, a rounded corner is set at the bottom edge of the assembly groove 702, and the setting of the rounded corner can make it easier for the support rod 601 to enter the assembly groove 702 within the allowable error range, thereby improving the fault tolerance rate when the assembly groove 702 and the support rod 601 are matched.

[0061] In one embodiment of the present invention, a guide rail groove is provided on the top surface of the support rail 5, and a sliding sleeve 603 is provided at the lower end of the support frame 6. The sliding sleeve 603 is slidably connected to the guide rail groove. Specifically, the guide rail groove extends to the two ends of the support rail 5 along the length direction of the support rail, and when the spacing between the lower ends of the two support rods 601 is adjusted, it is ensured that the sliding sleeve 603 can slide freely in the guide rail groove. Preferably, the axial direction of the sliding sleeve 603 is perpendicular to the length direction of the support rail 5, and the two end surfaces of the sliding sleeve 603 fit the two symmetrical side surfaces in the guide rail groove.

[0062] To ensure that the support frame 6 can be stably placed on the support rail 5 when supporting the photovoltaic module 1 in the unfolded state, a plurality of limit holes are arranged in an array on the side of the support rail 5, and the axes of the limit holes are parallel to the axis of the sliding sleeve 603, and the axes of the plurality of limit holes are all located in the same horizontal plane as the axis of the sliding sleeve 603. When the height adjustment of the support frame 6 is completed, the sliding sleeve 603 is stabilized on the support rail 5 and is coaxial with one of the limit holes. The limit pin passes through the limit hole and the sliding sleeve 603 to lock the sliding sleeve 603 on the support rail 5, thereby preventing the sliding sleeve 603 from sliding on the support rail 5, and effectively improving the stability of the support frame 6 when supporting the photovoltaic module 1 in the unfolded state.

[0063] Preferably, a plurality of first teeth are arranged in an array on the bottom surface of the guide rail groove (not shown in the figure), and a plurality of second teeth are arranged in an array on the bottom surface of the sliding sleeve 603 (not shown in the figure). When the height adjustment of the support frame 6 is completed, the sliding sleeve 603 is stabilized on the support rail 5, and the first teeth are engaged with the second teeth to further lock the position of the sliding sleeve 603 on the support rail 5, thereby improving the stability of the support frame 6 when supporting the photovoltaic assembly 1 in the unfolded state.

[0064] like Fig. 9 As shown, in one embodiment of the present invention, the upper end of one of the support rods 601 is connected to the assembly slot 701 through the first rotating axis, and the upper end of the other support rod 601 is connected to the assembly slot 701 through the second rotating axis. By rotating the first rotating axis and the second rotating axis, the angles of the two support rods 601 and the fixed beam 7 are adjusted and locked, so that the fixed beam 7 has a certain angle with the horizontal plane. Preferably, the acute angle between the top surface of the fixed beam 7 and the horizontal plane is 45°, so that the first photovoltaic panel 101, the second photovoltaic panel 102 and the third photovoltaic panel 103 can all be at the best solar irradiation angle, thereby ensuring the power generation efficiency of the photovoltaic module 1. In addition, a limit frame is set at the end of the fixed beam 7, and one end of the limit frame is inserted into the end surface of the fixed beam 7. After adjusting the angle of the fixed beam 7, the limit frame can play a certain supporting role on the first photovoltaic panel 101, the second photovoltaic panel 102 and the third photovoltaic panel 103, thereby enhancing the stability of the connection between the photovoltaic module 1 and the fixed beam 7, so that it can cope with strong winds, animal collisions, etc., so that it is suitable for places with complex outdoor environments.

[0065] like Fig.13 As shown, it should be noted that, in order to ensure that the illuminated surface of the first photovoltaic panel 101 stably fits the illuminated surface of the second photovoltaic panel 102 when the photovoltaic assembly 1 is in a folded state, a first limit axis 8 is set on the side of the first photovoltaic panel 101, and a second limit axis 9 is set on the side of the third photovoltaic panel 103. When the photovoltaic assembly 1 is switched to a folded state, the first limit axis 8 and the second limit axis 9 are connected by a fixed plate 10. Specifically, a first limit slot is set at the upper end of the fixed plate 10, and a second limit slot is set at the lower end of the fixed plate 10. The first limit slot is sleeved on the first limit axis 8, and the second limit slot is sleeved on the second limit axis 9, so that the first photovoltaic panel 101 can stably fit the third photovoltaic panel 103, so as to prevent the back of the first photovoltaic panel 101 and the illuminated surface of the third photovoltaic panel 103 from colliding with each other during the transportation of the overall movable photovoltaic power source, thereby protecting the photovoltaic assembly 1.

[0066] The working principle of the present invention is as follows: in the initial state, the photovoltaic assembly 1 is in a folded state and stored in the slot box 4. When continuous power supply is required, the total height of the two support frames 6 is adjusted, and the lower ends of the two support frames 6 are fixed to the bracket guide rails 5. The photovoltaic assembly 1 in the folded state is placed on the support frame 6, and the third photovoltaic panel 103 is flipped until the side of the third photovoltaic panel 103 is in contact with the side of the second photovoltaic panel 102. The third photovoltaic panel 103 and the second photovoltaic panel 102 are locked by the second fixing clamp 3. The first photovoltaic panel 101 is flipped until the side of the first photovoltaic panel 101 is in contact with the side of the second photovoltaic panel 102, and the first photovoltaic panel 101 is locked by the first fixing clamp 2. 101 and the second photovoltaic panel 102; when power supply is no longer needed, flip the first photovoltaic panel 101 until the illuminated surface of the first photovoltaic panel 101 fits the illuminated surface of the second photovoltaic panel 102, use the first fixing clamp 2 to lock the first photovoltaic panel 101 and the second photovoltaic panel 102, flip the second photovoltaic panel 102 until it fits the illuminated surface of the third photovoltaic panel 103 and the backlight surface of the first photovoltaic panel 101, use the second fixing clamp 3 to lock the third photovoltaic panel 103 and the second photovoltaic panel 102, convert the photovoltaic assembly 1 from the unfolded state to the folded state, adjust the support frame 6 to fold it and store it in the trough box 4, and place the folded photovoltaic assembly 1 in the trough box 4.

[0067] In summary, by switching the structural state of the photovoltaic module 1 according to the needs, after switching the photovoltaic module 1 to the unfolded state, the illumination area of ​​the entire photovoltaic module 1 can be expanded, and the power generation power of the photovoltaic module 1 can be effectively increased, solving the problem that traditional mobile power supplies are difficult to use in occasions where high-power batteries are temporarily powered, and providing a stable power supply, so as to flexibly adapt to a variety of scenarios that require a large amount of electricity. Furthermore, the photovoltaic module 1 is switched to a folded state and placed in the slot box 4, which is convenient to carry, so as to quickly respond to various energy needs, which has obvious advantages in occasions where high-power batteries are required for temporary power supply.
