DETAILED DESCRIPTION

[0028] Example 1, please refer to Figure 1-9 A retractable photovoltaic module system comprises a main box body 1, a top photovoltaic panel 101 is fixed on the top of the main box body 1, slide rails 2 are fixed at the front and rear ends and the left and right ends inside the main box body 1, inner sliders 201 are embedded inside the slide rails 2, two inner sliders 201 at the same height are fixed with buckles 202 at one end close to the middle of the main box body 1, a first telescopic component, a second telescopic component, a third telescopic component and a fourth telescopic component are equidistantly arranged from top to bottom inside the main box body 1, servo motors 8 are fixed at the left and right ends and the front and rear ends inside the main box body 1 through brackets, electric push rods 10 are fixed to the four corners of the outer wall of the main box body 1 through brackets, a mounting plate 11 is nested under the outer wall of the main box body 1, an extension plate 12 is fixed above the mounting plate 11, and the front and rear ends and left and right ends inside the extension plate 12 are connected to sealing plates 13 through return springs.

[0029] The first telescopic assembly is composed of a photovoltaic panel bracket 3, a snap buckle 301, an outer buckle 302 and a first telescopic photovoltaic panel 4, the second telescopic assembly is composed of a photovoltaic panel bracket 3, a snap buckle 301, an outer buckle 302 and a second telescopic photovoltaic panel 5, the third telescopic assembly is composed of a photovoltaic panel bracket 3, a snap buckle 301, an outer buckle 302 and a third telescopic photovoltaic panel 6, and the fourth telescopic assembly is composed of a photovoltaic panel bracket 3, a snap buckle 301, an outer buckle 302 and a fourth telescopic photovoltaic panel 7;

[0030] Photovoltaic panel brackets 3 are embedded inside two clips 202 at the same height, and the first telescopic photovoltaic panel 4, the second telescopic photovoltaic panel 5, the third telescopic photovoltaic panel 6 and the fourth telescopic photovoltaic panel 7 are fixed between the two photovoltaic panel brackets 3 respectively, and a snap buckle 301 is fixed at one end of the photovoltaic panel bracket 3 away from the middle of the main box body 1, and an outer buckle 302 is fixed on the outer wall of the snap buckle 301.

[0031] The cross-sectional areas of the first telescopic photovoltaic panel 4, the second telescopic photovoltaic panel 5, the third telescopic photovoltaic panel 6 and the fourth telescopic photovoltaic panel 7 are the same, and racks 9 are fixed to the bottoms of the first telescopic photovoltaic panel 4, the second telescopic photovoltaic panel 5, the third telescopic photovoltaic panel 6 and the fourth telescopic photovoltaic panel 7, and the gear plates at the power output ends of the four servo motors 8 are respectively meshed with the racks 9 at the bottoms of the first telescopic photovoltaic panel 4, the second telescopic photovoltaic panel 5, the third telescopic photovoltaic panel 6 and the fourth telescopic photovoltaic panel 7;

[0032] The first telescopic photovoltaic panel 4 and the second telescopic photovoltaic panel 5 slide horizontally left and right in the main box 1, and the first telescopic photovoltaic panel 4 and the second telescopic photovoltaic panel 5 can be extended from the right side and the left side of the main box 1 respectively, and the third telescopic photovoltaic panel 6 and the fourth telescopic photovoltaic panel 7 slide horizontally forward and backward in the main box 1, and the third telescopic photovoltaic panel 6 and the fourth telescopic photovoltaic panel 7 can be extended from the front end and the rear end of the main box 1 respectively;

[0033] During the operation of the servo motor 8, its power output end drives the gear plate to rotate at the bottom of the rack 9 at the bottom of the first telescopic photovoltaic panel 4, the second telescopic photovoltaic panel 5, the third telescopic photovoltaic panel 6 and the fourth telescopic photovoltaic panel 7, so that the first telescopic photovoltaic panel 4 and the second telescopic photovoltaic panel 5 slide to the left and right in the main box 1 and extend from the right and left sides above the main box 1, while the third telescopic photovoltaic panel 6 and the fourth telescopic photovoltaic panel 7 slide forward and backward in the main box 1 and extend from the front and rear ends below the main box 1, so that the first telescopic photovoltaic panel 4, the second telescopic photovoltaic panel 5, the third telescopic photovoltaic panel 6, the fourth telescopic photovoltaic panel 7 and the top photovoltaic panel 101 can generate electricity together at the same time, further increasing the area of ​​the photovoltaic panels;

[0034] The snap-on buckles 301 on the front and rear photovoltaic panel brackets 3 of the first telescopic photovoltaic panel 4 and the second telescopic photovoltaic panel 5 are all on the same horizontal plane as the inner slider 201, and the vertical section area of ​​the snap-on buckles 301 on the front and rear ends of the first telescopic photovoltaic panel 4 and the second telescopic photovoltaic panel 5 is consistent with the vertical section area of ​​the inner slider 201;

[0035] The snap-on buckles 301 on the photovoltaic panel brackets 3 at the left and right ends of the third telescopic photovoltaic panel 6 and the fourth telescopic photovoltaic panel 7 are all on the same longitudinal horizontal plane as the inner slider 201, and the cross-sectional area of ​​the left and right electrical snap-on buckles 301 of the third telescopic photovoltaic panel 6 and the fourth telescopic photovoltaic panel 7 is consistent with the cross-sectional area of ​​the inner slider 201;

[0036] When the first telescopic photovoltaic panel 4 is not moved out of the main box body 1, the slide rail 2 supports and fixes the first telescopic photovoltaic panel 4 through the buckle 202 and the photovoltaic panel bracket 3. When the first telescopic photovoltaic panel 4 is extended more than half, the snap buckle 301 on the photovoltaic panel bracket 3 under the first telescopic photovoltaic panel 4 is snap-fitted with the inner slider 201 in the slide rail 2, and at the same time drives the inner slider 201 to move to the right.

[0037] Example 2, please refer to Figure 1-9 , Embodiment 2 is different from Embodiment 1 in that the outer buckle 302 is fixed to an end of the outer wall of the snap buckle 301 away from the middle of the main box body 1, and the outer buckle 302 is arranged in an "L" shape;

[0038] When the first telescopic photovoltaic panel 4 is completely extended from the right side of the main box 1, the last outer buckle 302 on the snap buckle 301 will contact the outer wall of the slide rail 2 to prevent the photovoltaic panel bracket 3 from being completely separated from the slide rail 2, so as to drive the inner slider 201 in the slide rail 2 to move normally;

[0039] The length of the slide rail 2 is shorter than the length of the first telescopic photovoltaic panel 4, and the length of the slide rail 2 is one third of the length of the first telescopic photovoltaic panel 4;

[0040] Since the length of the slide rail 2 is relatively short, the total weight of the slide rail 2 is reduced while the length of the slide rail 2 is reduced, thereby further reducing the production cost of the photovoltaic module;

[0041] When the first telescopic photovoltaic panel 4 moves to the right and completely extends out from the right side of the main box body 1, the slide rail 2 is also completely combined with the first telescopic photovoltaic panel 4, and all the weight of the first telescopic photovoltaic panel 4 is borne by the slide rail 2, the inner slider 201, the buckle 202 and the photovoltaic panel bracket 3.

[0042] Example 3, please refer to Figure 1-2 , Embodiment 3 is different from Embodiment 2 in that a main bus bar is provided on the left side inside the main box 1, the main bus bar is electrically connected to the top photovoltaic panel 101, the first telescopic photovoltaic panel 4, the second telescopic photovoltaic panel 5, the third telescopic photovoltaic panel 6 and the fourth telescopic photovoltaic panel 7 through a power line, the main bus bar is electrically connected to the MPPT photovoltaic controller through a control line, and the MPPT photovoltaic controller is electrically connected to the PDU power distribution unit through a power line;

[0043] When the top photovoltaic panel 101, the first telescopic photovoltaic panel 4, the second telescopic photovoltaic panel 5, the third telescopic photovoltaic panel 6 and the fourth telescopic photovoltaic panel 7 are working, the MPPT is responsible for tracking the maximum power point of each photovoltaic panel or each group of photovoltaic strings, so that they can output electrical energy in the best state, and can gather these multiple DC powers processed by MPPT to form a centralized power output, which is convenient for subsequent unified power supply to the load or connection with other equipment. After connecting to the PDU, the DC power output by the MPPT can be distributed to multiple different loads or equipment branches to realize power supply to multiple electrical equipment and meet the power requirements of different equipment.

[0044] Example 4, please refer to Figure 1-2, Embodiment 4 is different from Embodiment 3 in that the bottoms of the push rods at the output ends of the four electric push rods 10 are connected to the extension plate 12, the inner walls of the extension plate 12 and the mounting plate 11 are in close contact with the outer wall of the main box body 1, the four sealing plates 13 are just embedded in the openings at the front, rear, left and right ends of the main box body 1, the volumes of the four sealing plates 13 are respectively consistent with the hollow volumes of the openings at the front, rear, left and right ends of the main box body 1, and the ends of the sealing plates 13 away from the middle of the main box body 1 are embedded in the hidden grooves inside the extension plate 12;

[0045] When extending from the opening of the outer box body 1, the first telescopic photovoltaic panel 4, the second telescopic photovoltaic panel 5, the third telescopic photovoltaic panel 6 and the fourth telescopic photovoltaic panel 7 will pre-push the sealing plate 13 embedded in the opening of the outer box body 1 to hide in the extension plate 12 to squeeze the return spring to compress, and then the electric push rod 10 pushes the mounting plate 11, the extension plate 12 and the sealing plate 13 to move downward, and the first telescopic photovoltaic panel 4, the second telescopic photovoltaic panel 5, the third telescopic photovoltaic panel 6 and the fourth telescopic photovoltaic panel 7 can be normally extended from the opening of the outer box body 1. After extending, the top of the extension plate 12 will be close to the bottom of the first telescopic photovoltaic panel 4, the second telescopic photovoltaic panel 5, the third telescopic photovoltaic panel 6 and the fourth telescopic photovoltaic panel 7 to support them and prevent them from shaking during use;

[0046] When the first telescopic photovoltaic panel 4, the second telescopic photovoltaic panel 5, the third telescopic photovoltaic panel 6 and the fourth telescopic photovoltaic panel 7 are stored into the main box body 1, the electric push rod 10 pushes the mounting plate 11, the extension plate 12 and the sealing plate 13 to move up and return to their original positions. When the extension plate 12 covers the opening of the main box body 1, the return spring generates a rebound force to push the sealing plate 13 to be embedded in the opening of the main box body 1 to further seal the opening of the main box body 1, thereby preventing foreign objects such as external rainwater from entering the interior of the main box body 1 along the opening of the main box body 1 when not in use and affecting the normal operation of the photovoltaic module.

[0047] The above are only preferred embodiments of the present invention. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the protection scope of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
