When used in a high-temperature or low-temperature environment, the photovoltaic power generation panel 1 is placed in an inclined state on the top of the containing box 2 after being folded, so as to achieve the effects of high-temperature sun-shading and low-temperature heat-preservation.

[0033] The energy storage assembly comprises a containing box 2 and a battery block, the battery block being arranged inside the containing box 2, and one end of the containing box 2 being fixed with a settling belt 3.

[0034] It is worth noting that the settling belt 3 can form a blocking effect on dust in the air, so as to avoid excessive dust from entering the photovoltaic power generation panel 1 and the surface of the containing box 2 to affect heat dissipation of the containing box 2. At the same time, the settling belt 3 can block part of the air from entering when the weather is cold, so that the heat stays for a longer time, thereby avoiding low temperature of the containing box 2 and affecting the energy storage capacity of the energy storage module.

[0035] The suspension assembly comprises a suspension bracket 4, a telescopic arm 13 and a driving assembly. Further, the driving assembly comprises a stepping motor 17, and the middle part of the stepping motor 17 is connected with a lifting rod 11 through a threaded groove.

[0037] The fixing assembly further comprises an expansion bolt 18 inserted into the inner wall of the convex plate on the inner side of the suspension bracket 4.

[0038] The above further advantage is that the expansion bolt 18 can fix the suspension bracket 4 on the wall, so that the device is more suitable for household use environment, and prevents moisture or rainwater from entering the containing box 2, thereby preventing the energy storage module from being accelerated aging or short-circuited due to moisture.

[0039] The reaction force assembly further comprises a transmission belt 22 sleeved on one end of a support horizontal shaft 21, one end of the transmission belt 22 is inserted with a tension pulley 23, the inner wall of the tension pulley 23 is hinged to the surface of the containing box 2 through a shaft, one end of the tension pulley 23 is engaged with a turnover wheel 24, the inner wall of the turnover wheel 24 is hinged to the surface of the containing box 2 through a shaft, and the outer side of the turnover wheel 24 is fixedly connected with the telescopic arm 13.

[0043] The top end fastening assembly further includes an inner fastening lifting handle 19 fixed to the top end of the lifting rod 11 and a top end traction rod 20 hinged to the inner side of the hanging bracket 4 through a shaft, the inner wall of the top end traction rod 20 is inserted with a support cross shaft 21, and both ends of the support cross shaft 21 penetrate the housing box 2.

[0044] The further advantage of the above is that when the housing box 2 is supported from the bottom by the overturning support rod 10, the top end of the housing box 2 can move downward under the action of the top end traction rod 20, and the top end of the housing box 2 is away from the hanging bracket 4, and the overturning support rod 10 changes the housing box 2 from a vertical state to an inclined state, so that the photovoltaic panel 1 can better shield the housing box 2 to reduce light and avoid high temperature, or the photovoltaic panel 1 can provide heat preservation effect for the housing box 2 in low temperature.

[0045] It is worth noting that the inner fastening lifting handle 19 can lift one end of the top end traction rod 20 upward after following the lifting rod 11 upward, so that the top end of the housing box 2 can be fastened to the top end of the hanging bracket 4 when placed vertically.

[0046] The outer side of the hanging bracket 4 is provided with a matching overturning sliding groove 5, the inner wall of the matching overturning sliding groove 5 is provided with a following sliding block 6, one end of the following sliding block 6 is hinged with a bottom pushing rod 7, one end of the bottom pushing rod 7 is fixed with a limiting pushing rod 8, the middle part of the limiting pushing rod 8 is sleeved with an overturning tongue rack 9, one end of the overturning tongue rack 9 is fixed with an overturning support rod 10, one end of the overturning support rod 10 is closely attached to the surface of the housing box 2, one end of the overturning tongue rack 9 is sleeved with a lifting rod 11, both ends of the lifting rod 11 are connected with the hanging bracket 4 through built-in sliding grooves 12, and the inner wall of the telescopic arm 13 is connected with a following rod 15 through a stretching spring 14.

[0047] The top end of the following rod 15 is connected with the extrusion plate 16 through the reset assembly, further, the reset assembly comprises a T-shaped bolt 27 inserted into the inner wall of the following rod 15, one end of the T-shaped bolt 27 is fixed to the surface of the extrusion plate 16, and the following spring 28 is fixed between the T-shaped bolt 27 and the surface of the following rod 15.

[0048] The further advantage of the above is that the extrusion plate 16 can be close to the surface of the containing box 2 by the following spring 28 when sliding from the top end to the side, so that the extrusion plate 16 moves away from the telescopic arm 13 direction, and then the photovoltaic panel 1 changes from the flat state to the folded state, and the containing box 2 is shaded or insulated.

[0049] The end of the extrusion plate 16 close to the containing box 2 is provided with an inclined surface.

[0050] It is worth noting that the end of the extrusion plate 16 is provided with an inclined surface, so that the telescopic arm 13 and the following rod 15 can be telescoped when the extrusion plate 16 slides along the side rib of the containing box 2, the photovoltaic panel 1 is close to the containing box 2, and the extrusion plate 16 can slide in the following rod 15 to make the photovoltaic panel 1 change to the folded state.

[0051] In use, the output end of the step drive motor 17 rotates to drive the lifting rod 11 to move downward along the built-in sliding groove 12;

[0052] When the lifting rod 11 moves downward, the following sliding block 6 moves downward in the cooperation of the turnover sliding groove 5, when the following sliding block 6 moves to the bottom of the cooperation of the turnover sliding groove 5, the lifting rod 11 continues to move downward, the bottom pushing rod 7 can drive the turnover tongue frame 9 to change from the vertical state to the inclined state through the limiting pushing rod 8, and when the turnover supporting rod 10 rotates following the turnover tongue frame 9, the bottom of the containing box 2 can be lifted, so that the containing box 2 changes from the vertical state to the inclined state;

[0053] In the process of being pushed by the turnover supporting rod 10, the inner buckle lifting handle 19 is away from the top end traction rod 20, the top end traction rod 20 is turned over, and the side of the top end traction rod 20 is supported at the top of the containing box 2, when the lifting rod 11 moves downward, the turnover supporting rod 10 and the top end traction rod 20 form a lever system, and the two are rigidly connected through the supporting horizontal shaft 21, so as to ensure that the top and the bottom of the containing box 2 are relatively displaced during the tilting process, the displacement is enlarged through the transmission belt 22, and then the photovoltaic panel 1 is moved and changed in position and form through the rotation of the turnover wheel 24.

[0054] The rotation of the top end traction rod 20 can drive the supporting horizontal shaft 21 to rotate, and then drive the tensioning wheel 23 to rotate through the transmission belt 22, the rotation of the tensioning wheel 23 can drive the turnover wheel 24 to rotate, so that the photovoltaic panel 1 moves from the top of the containing box 2 to the side.

[0055] In the process of rotating the turnover wheel 24, the inclined surface of the pressing plate 16 slides along the top of the housing box 2, and the rod 15 can be moved to the inner wall of the telescopic arm 13 under the traction of the extension spring 14. When the pressing plate 16 moves from the top end to the side of the housing box 2, the two pressing plates 16 are close to each other under the action of the inclined surface, so that the two ends of the photovoltaic power generation panel 1 are relatively moved, which can promote the photovoltaic power generation panel 1 to change from the flat state to the folded state, so as to reduce the light irradiation on the surface of the housing box 2 and prevent high temperature. The photovoltaic power generation panel 1 is folded and placed at a certain angle with the housing box 2, which can guide the heat to be dissipated from the folding corner of the photovoltaic power generation panel 1 in high temperature environment, and in low temperature environment, since the gap between the photovoltaic power generation panel 1 and the housing box 2 is small, the heat retention time is also long, thereby forming a heat preservation effect.

[0056] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes to the technical solutions and the inventive concept of the present application within the technical scope disclosed by the present application, which should be covered by the protection scope of the present application.
