It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0028] Embodiment: An automatically unfolded foldable photovoltaic solar panel, see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig.10 As shown; it includes a photovoltaic panel 1, six photovoltaic panels 1 are arranged at intervals from left to right, and the six photovoltaic panels 1 are marked as one, two, three, four, five and six from left to right; it also includes a connecting column 2, a hinged plate 3, a first slider 4, a gear set 5, a guide frame 6, a second slider 7, a limit bar 11, a moving mechanism and a limit mechanism; the lower sides of the two photovoltaic panels 1 on the left and right are symmetrically connected to the connecting column 2; the two adjacent photovoltaic panels 1 are symmetrically connected to each other in front and back rotation, and the hinged plates 3 are staggered up and down, and the hinged plates 3 are used to connect the two adjacent photovoltaic panels 1. Through the contact of the two adjacent hinged plates 3 on the same side and above, the two adjacent photovoltaic panels 1 can maintain a certain distance to avoid the two adjacent photovoltaic panels 1 from being squeezed against each other due to being too close; the bottom of the hinged plate 3 on the lower side is connected to the first slider 4; the gear set 5 is composed of a plurality of gears, wherein the upper parts of the front and rear sides of the two photovoltaic panels 1 on the left and right are connected to gears, and the upper and lower sides of the front and rear sides of the remaining four photovoltaic panels 1 are connected The first and second photovoltaic panels 1 are connected with gears, the gears on the upper side of the second photovoltaic panel 1 are meshed, the gears on the lower side of the second photovoltaic panel 1 are meshed, the gears on the upper side of the third photovoltaic panel 1 are meshed, the gears on the lower side of the fourth photovoltaic panel 1 are meshed, and the gears on the upper side of the fifth photovoltaic panel 1 are meshed; a guide frame 6 is symmetrically arranged front and back below the photovoltaic panel 1, and a slide groove is designed on the guide frame 6 to accommodate the first slider 4; a second slider 7 is slidably arranged in the guide frame 6; a gear for driving the first and second photovoltaic panels 1 is arranged on the guide frame 6. A moving mechanism for moving the two sliders 7 is used to unfold the six folded photovoltaic panels 1; arc grooves 9 are provided on the right side of the top of the guide frame 6 and on the top of the second slider 7, and the arc grooves 9 are used to load the connecting columns 2 on the photovoltaic panels 1; a limiting mechanism is provided between the guide frame 6 and the second slider 7, and the limiting mechanism is used to limit the connecting columns 2 loaded into the arc grooves 9; a limiting strip 11 is symmetrically provided on the upper side of the guide frame 6, and the limiting strip 11 is used to limit the first slider 4 inserted into the guide frame 6.

[0029] See also Figure 3 and Figure 4As shown, the moving mechanism includes a servo motor 801 and a screw 802; the servo motor 801 is installed on the right side of the guide frame 6; the screw 802 is rotatably installed on the inner side of the guide frame 6, the right end of the screw 802 is connected to the output shaft of the servo motor 801, and the second slider 7 is threadedly connected to the screw 802.

[0030] See also Figure 3 and Figure 4 As shown, the limiting mechanism includes a limiting plate 1001 and a bolt 1002; the limiting plate 1001 is rotatably installed on the top of the second slider 7 and the right side of the top of the guide frame 6, and the limiting plate 1001 is arc-shaped. The limiting plate 1001 is used to limit the connecting column 2 inserted into the arc groove 9; the limiting plate 1001 is threadedly installed with a bolt 1002, and the bolt 1002 on the limiting plate 1001 is installed into the top of the second slider 7 or the right side of the top of the guide frame 6, and the limiting plate 1001 can be limited by the bolt 1002.

[0031] When in use, first install the guide frame 6 at the specified position, then place the photovoltaic panel 1 between the two guide frames 6, so that the connecting column 2 on the rightmost photovoltaic panel 1 is placed in the arc groove 9 on the guide frame 6, and the connecting column 2 on the leftmost photovoltaic panel 1 is placed in the arc groove 9 on the second slider 7, and at the same time, the first slider 4 is inserted into the guide frame 6, and then the limit plate 1001 is pulled to rotate, so that the limit plate 1001 limits the connecting column 2 installed in the arc groove 9, and then the limit plate 1001 is fixed with the bolt 1002 (such as Figure 3 As shown), in this way, the photovoltaic panel 1 can be installed;

[0032] When the six photovoltaic panels 1 need to be unfolded, the servo motor 801 is controlled to drive the screw rod 802 to rotate, so that the screw rod 802 drives the second slider 7 to move to the left, thereby driving the six photovoltaic panels 1 to gradually unfold. During the unfolding of the six photovoltaic panels 1, the gear set 5 provided on the photovoltaic panels 1 can make the six photovoltaic panels 1 unfold synchronously, and the synchronous unfolding mechanism can ensure that all photovoltaic panels 1 are unfolded at the same time and in the same way, thereby improving the reliability and stability between the photovoltaic panels 1. When the six photovoltaic panels 1 are unfolded, the photovoltaic panel 1 will drive the first slider 4 to move to the left in the guide frame 6, so that the guide frame 6 contacts the limit bar 11, so that the limit bar 11 limits the guide frame 6, thereby providing support and holding the middle area of ​​the six photovoltaic panels 1 to prevent the middle area of ​​the six photovoltaic panels 1 from being sunken or convex. After the six photovoltaic panels 1 are unfolded (such as Fig.10 As shown), then control the servo motor 801 to drive the screw rod 802 to stop rotating;

[0033] When the six photovoltaic panels 1 need to be folded, the servo motor 801 is controlled to drive the lead screw 802 to reverse and reset, so that the lead screw 802 drives the second slider 7 to move right and reset, thereby driving the six photovoltaic panels 1 to be gradually folded. During the period, when the six photovoltaic panels 1 are folded, the gear set 5 arranged on the photovoltaic panels 1 can make the six photovoltaic panels 1 fold synchronously, and the synchronous folding mechanism can ensure that all photovoltaic panels 1 are folded at the same time and in the same way, thereby improving the reliability and stability between the photovoltaic panels 1. When the six photovoltaic panels 1 are folded, the photovoltaic panel 1 will drive the first slider 4 to move right and reset in the guide frame 6, so that the guide frame 6 is separated from the limit bar 11, so that the limit bar 11 releases the limit on the guide frame 6, and after the six photovoltaic panels 1 are folded (such as Figure 1 As shown), then control the servo motor 801 to drive the screw rod 802 to stop reversing;

[0034] When the photovoltaic panels 1 need to be removed, the six photovoltaic panels 1 are first folded, and then the limit plate 1001 is released by the bolt 1002, and then the limit plate 1001 is pulled to reverse and reset, so that the limit plate 1001 releases the limit on the connecting column 2 inserted into the arc groove 9, and then the six photovoltaic panels 1 can be taken away together.

[0035] See also Figure 5 and Figure 6 As shown, an alarm mechanism is also included, which includes a rubber block 12, a patch pressure sensor 13, a controller 14 and an alarm 15; the two photovoltaic panels 1 adjacent to the leftmost and rightmost photovoltaic panels 1 are symmetrically connected to the rubber blocks 12, and the number of rubber blocks 12 is four; the patch pressure sensors 13 are installed on the sides of the four rubber blocks 12 away from each other, the controller 14 is connected to the bottom of the rightmost photovoltaic panel 1, and the patch pressure sensor 13 is electrically connected to the controller 14, and the alarm 15 is connected to the bottom of the rightmost photovoltaic panel 1, and the alarm 15 is located on the rear side of the controller 14, and the controller 14 is electrically connected to the alarm 15.

[0036] When the six photovoltaic panels 1 are unfolded, the photovoltaic panels 1 on the far left and the far right will be separated from the patch pressure sensor 13; when the six photovoltaic panels 1 are folded, the photovoltaic panels 1 on the far left and the far right will contact the patch pressure sensor 13, and as the photovoltaic panels 1 on the far left and the far right continue to apply pressure to the patch pressure sensor 13, the pressure sensed by the patch pressure sensor 13 will gradually increase. When the patch pressure sensor 13 senses that the pressure is greater than the preset value, the patch pressure sensor 13 will send a signal, and the controller 14 will control the alarm 15 to start the alarm after receiving the signal. After receiving the alarm signal, the operator will control the servo motor 801 to drive the screw rod 802 to stop reversing. In this way, the pressure applied by the photovoltaic panels 1 on the far left and the far right to the patch pressure sensor 13 can stop increasing, so that the pressure sensed by the patch pressure sensor 13 stops increasing, thereby preventing the photovoltaic panels 1 on the far left and the far right from being too close to the adjacent photovoltaic panels 1, and avoiding the two photovoltaic panels 1 from being damaged due to being too close.

[0037] See also Figure 7 As shown, positioning blocks 16 are also included. Positioning blocks 16 are symmetrically arranged at the bottom of the two photovoltaic panels 1 on the leftmost and rightmost sides. The positioning blocks 16 are used to guide the photovoltaic panels 1 to be positioned between the two guide rail frames 6. The four positioning blocks 16 are provided with inclined surfaces on the sides away from each other.

[0038] The design of the positioning block 16 helps the photovoltaic panel 1 to automatically align with the guide frame 6 when placed. When the photovoltaic panel 1 is placed between the two guide frames 6, the inclined surface of the positioning block 16 will contact the guide frame 6, causing the positioning block 16 to be slightly offset, thereby helping the photovoltaic panel 1 to be accurately aligned.

[0039] See also Figure 8 and Fig. 9 As shown, it also includes a tightening mechanism, which includes a connecting frame 17, a winding wheel 18, a strap 19, a clamp 20 and a torsion spring 21; the photovoltaic panel 1 on the far right is symmetrically provided with a connecting frame 17; the winding wheels 18 are rotatably installed in the two connecting frames 17; a strap 19 is wound around the winding wheel 18, one end of the strap 19 is connected to the winding wheel 18, and the other end of the strap 19 is connected to the clamp 20, the clamp 20 is located on the outside of the connecting frame 17, and the clamp 20 is clamped on the far left photovoltaic panel 1; a torsion spring 21 is connected between the winding wheel 18 and the bottom of the connecting frame 17.

[0040] In the initial state, since the clamp 20 is clamped on the photovoltaic panel 1 on the far left, the winding wheel 18 unwinds the strap 19 and causes the torsion spring 21 to be deformed;

[0041] When the photovoltaic panel 1 is installed, the clamp 20 is removed from the leftmost photovoltaic panel 1. At this time, the torsion spring 21 returns to its original state, and the torsion spring 21 drives the winding wheel 18 to rotate, so that the winding wheel 18 rewinds the strap 19, so that the strap 19 drives the clamp 20 to move to the right until it is close to the outer wall of the connecting frame 17; when the photovoltaic panel 1 needs to be removed, the six photovoltaic panels 1 are first folded, and then the clamp 20 is pulled out to the left, so that the clamp 20 drives the strap 19 to unwind from the winding wheel 18, so that the strap 19 drives the winding wheel 18 to reverse, the torsion spring 21 is deformed, and then the clamp 20 is clamped on the leftmost photovoltaic panel 1 again (such as Figure 8 As shown), the winding wheel 18, the strap 19 and the clamp 20 can be used to limit the leftmost photovoltaic panel 1, so that the six photovoltaic panels 1 can be tightened, which is not only convenient for transportation but also can prevent the six photovoltaic panels 1 from becoming loose after being removed together by the operator.

[0042] See also Fig. 9 As shown, it also includes a resistance increasing mechanism, which includes a screw 22 and a friction block 23; the screw 22 is threadedly connected to the upper right side of the connecting frame 17; a friction block 23 is slidably arranged on the top of the connecting frame 17, the friction block 23 contacts the winding wheel 18, and the left end of the screw 22 is rotatably connected to the friction block 23.

[0043] See also Fig. 9 As shown, a knob 24 is also included. The right end of the screw rod 22 is connected to the knob 24 , and the knob 24 is located outside the connection frame 17 .

[0044] Before removing the clamp 20 from the leftmost photovoltaic panel 1, first twist the knob 24 to rotate it so that the knob 24 drives the screw 22 to rotate, thereby causing the screw 22 to drive the friction block 23 to move to the right, thereby separating the friction block 23 from the winding wheel 18. At this time, the resistance encountered by the winding wheel 18 during rotation is reduced, and then the clamp 20 can be removed from the leftmost photovoltaic panel 1; after the clamp 20 is re-clamped on the leftmost photovoltaic panel 1, the knob 24 is twisted to reverse and reset, so that the knob 24 drives the screw 22 to reverse and reset, thereby causing the screw 22 to drive the friction block 23 to move to the left and reset, thereby causing the friction block 23 to contact the winding wheel 18. At this time, the resistance encountered by the winding wheel 18 during rotation is increased, thereby further enhancing the limiting of the leftmost photovoltaic panel 1 by the winding wheel 18, the strap 19 and the clamp 20.

[0045] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto.
