[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiments of the present application disclose a self-contained photovoltaic panel energy storage package.

[0035] Example 1 Reference Figure 1 and Figure 2 The self-contained photovoltaic panel energy storage bag includes a carrying bag 1, a photovoltaic folding panel 2 and a retractable bracket 3. The carrying bag 1 can be opened or closed, so the carrying bag 1 has an unfolded state and a wrapped state; the photovoltaic folding panel 2 is movably connected to the carrying bag 1 to enter and exit the wrapping range of the carrying bag 1 in the unfolded state, and at the same time, the photovoltaic folding panel 2 is folded and rolled up with the sunny side facing inward; the retractable bracket 3 is connected to the carrying bag 1 and the photovoltaic folding panel 2 to support the photovoltaic folding panel 2.

[0036] Reference Figure 1 and Figure 2When in use, first open the carrying bag 1 and put it in the unfolded state, then open the photovoltaic folding panel 2 to a flat plate shape, and then open the retractable bracket 3 to make the photovoltaic folding panel 2 tilted and supported on the external support surface. When storing, first roll up the photovoltaic folding panel 2 with the sunny side facing inward, then send the photovoltaic folding panel 2 into the wrapping range of the carrying bag 1, and then close the carrying bag 1 and put it in the wrapped state. In summary, the photovoltaic folding panel 2 is rolled up, and rolled up with the sunny side facing inward, and is also wrapped with the storage bag, so that the device can be smaller in size when stored and the photovoltaic panel can be better protected.

[0037] Reference Figure 1 and Figure 2 In order to increase the photoelectric conversion efficiency of the device while keeping the size of the device small in the storage state, two photovoltaic folding panels 2 are provided. The two photovoltaic folding panels 2 are symmetrically arranged relative to the carrying bag 1. In this way, when the device is opened, there can be photovoltaic folding panels 2 on the left and right sides of the carrying bag 1, thereby increasing the photoelectric conversion efficiency without affecting the storage volume.

[0038] Reference Figure 1 and Figure 2 Since the photovoltaic panel energy storage bag also has an energy storage unit for storing electricity, in order to maintain a small volume in the storage state and to have sufficient space to load the energy storage unit when in use, the following settings are correspondingly provided: the carrying bag 1 is divided into a supporting portion 11, an exhibition board portion 12 and a packaging portion 13; the side of the supporting portion 11 away from the inner cavity is connected to the retractable bracket 3; the side of the supporting portion 11 close to the inner cavity is provided for the energy storage unit; the energy storage unit is detachably installed; the exhibition board portion 12 is hinged to the supporting portion 11; the two exhibition board portions 12 are respectively connected to two opposite sides of the supporting portion 11; one exhibition board portion 12 is connected to a photovoltaic folding panel 2; the packaging portion 13 connects the parts between the supporting portion 11 and the exhibition board portion 12 that are not connected to each other; the packaging portion 13 is used to wrap the photovoltaic folding panel 2, the energy storage unit and other components.

[0039] In the present embodiment, if the carrying bag 1 is made of a hard material as a whole, the support part 11 and the display panel part 12 can be hinged by a hinge, and the packaging part 13 can be connected to the support part 11 and the display panel part 12 by a strap with Velcro; if the carrying bag 1 is made of a soft cloth material as a whole, the support part 11 and the display panel part 12 can be hinged by the material, and the packaging part 13 can be connected to the support part 11 and the display panel part 12 by a zipper.

[0040] Reference Figure 1 and Figure 2In order to maintain the compactness of the photovoltaic folding panel 2 when rolled up and better protect the photovoltaic folding panel 2, the photovoltaic folding panel 2 includes a photovoltaic part 21 and a series part 22. The multiple photovoltaic parts 21 are distributed in a straight line, and the series part 22 is located between two adjacent photovoltaic parts 21. The series part 22 is formed into a bendable structure with the help of materials. The closer the series part 22 is to the carrying bag 1, the larger the width of the series part 22 is. The series part 22 is provided with a stacking-aiding hole 221, and the stacking-aiding hole 221 is a waist-shaped hole structure. In this way, the photovoltaic parts 21 can remain parallel when rolled up, so that the photovoltaic folding panel 2 can be protected and the compactness of the rolling can be maintained, thereby maintaining a small volume when stored.

[0041] Reference Figure 2 and Figure 3 Because the photovoltaic folding panel 2 is also connected to the retractable bracket 3, the retractable bracket 3 does not need to be installed separately when in use, and at the same time, the compactness of the photovoltaic folding panel 2 must be maintained. The following settings are correspondingly provided: the retractable bracket 3 includes a connecting plate 31, a supporting plate 32 and a stabilizing belt 33. The connecting plate 31 is connected to the back of the photovoltaic folding panel 2, one end of the supporting plate 32 is bent and connected to the connecting plate 31, and the other end abuts against the external supporting surface. The supporting plate 32 is provided with a through hole 321 at one end close to the connecting plate 31, one end of the stabilizing belt 33 is connected to the photovoltaic folding panel 2, the stabilizing belt 33 is passed through the through hole 321, and the other end of the stabilizing belt 33 is glued and connected to the side of the supporting plate 32 away from the photovoltaic folding panel 2.

[0042] Reference Figure 2 and Figure 3 The working principle of the retractable bracket 3 is as follows. When retracting, tear off the stabilizing belt 33 and the support plate 32 to allow the stabilizing belt 33 to leave the belt hole 321, and allow the support plate 32 to stick to the photovoltaic folding panel 2. This will not affect the rolling of the photovoltaic folding panel 2. When in use, you only need to change the connection position of the stabilizing belt 33 on the support plate 32, so that the angle between the support plate 32 and the photovoltaic folding panel 2 can be changed. In summary, when the retractable bracket 3 is opened or closed, it can not only maintain the small volume of the device in the retracted state, but also change the inclination angle of the photovoltaic folding panel 2 to adapt to sunlight at different angles.

[0043] Similarly, the retractable bracket 3 that cooperates with the carrying bag 1 , the connecting plate 31 , the supporting plate 32 and the stabilizing belt 33 are connected to the side of the supporting portion 11 away from the inner cavity to achieve the supporting function.

[0044] In addition, in this embodiment, considering the compactness of the photovoltaic folding plate 2 when rolled up, and the supporting stability of the photovoltaic folding plate 2, every two photovoltaic parts 21 are equipped with a retractable bracket 3.

[0045] The implementation principle of the photovoltaic panel energy storage bag of the embodiment of the present application is: when in use, first open the carrying bag 1 and put it in an unfolded state, then open the photovoltaic folding panel 2 to a flat plate shape, and then open the retractable bracket 3 to make the photovoltaic folding panel 2 tilted and supported on the external support surface, and when storing, first roll up the photovoltaic folding panel 2 with the sunny side facing inward, then send the photovoltaic folding panel 2 into the wrapping range of the carrying bag 1, and then close the carrying bag 1 and put it in a wrapped state. In summary, the photovoltaic folding panel 2 is rolled up, and rolled up with the sunny side facing inward, and is also wrapped with the storage bag, so that the device can be smaller in size when stored and the photovoltaic panel can be better protected.

[0046] Example 2 Reference Figure 4 , which is different from Example 1 in that: the carrying bag 1 is made of a hard material, and the portion of the packaging portion 13 close to the supporting portion 11 is provided with a facing motor 4, a driving gear 41, a driven gear 42 and an adsorption block 43, the facing motor 4 is arranged on a side of the packaging portion 13 close to the inner cavity, the output shaft of the facing motor 4 passes through a side of the packaging portion 13 away from the inner cavity, the driving gear 41 is connected to the output shaft of the facing motor 4, the driven gear 42 is rotatably connected to a side of the packaging portion 13 away from the inner cavity, the driven gear 42 is meshed with the driving gear 41, the adsorption block 43 is connected to the end surface of the driven gear 42 away from the packaging portion 13, and the adsorption block 43 is in the form of an elastic suction cup.

[0047] Reference Figure 4 The working principle is as follows. When in use, the adsorption block 43 can be adsorbed on a plane. When the direction of sunlight changes, the driving gear 41 is rotated by the direction motor 4, and the rotating driving gear 41 is meshed with the driven gear 42, so that the driving gear 41 rotates around the center of the driven gear 42, so that the carrying bag 1 as a whole can rotate relative to the adsorption block 43, so that the photovoltaic folding panel 2 can change synchronously with the direction of sunlight.

[0048] Reference Figure 4 In order to adapt to some more streamlined work requirements, the driving gear 41 is detachably connected to the packaging part 13, and the motor 4 is detachably connected to the packaging part 13. Specifically, the packaging part 13 is rotatably connected to a shaft, the driving gear 41 is detachably connected to the shaft, and the output shaft of the motor 4 is connected to the shaft through a coupling. Based on this structure, the adsorption block 43 can also serve the purpose of stabilizing the energy storage device.

[0049] Reference Figure 4 and Figure 5In order to adapt to the use situation where there is no ground or horizontal surface, the following settings are correspondingly arranged. The display panel part 12 is ball-hinged at the junction of the support part 11 and the packaging part 13. The display panel part 12 can be flipped to a position adjacent to the part of the packaging part 13 close to the support part 11. At this time, each photovoltaic folding panel 2 extends downward, so in conjunction with the adsorption block 43, the purpose of hanging the photovoltaic panel energy storage package can be achieved. At the same time, in order to improve the stability of the hanging use, an easy-to-tear adhesive block 5 is provided on the side of the display panel part 12 away from each other. The easy-to-tear adhesive block 5 is a reusable tape, and the easy-to-tear adhesive block 5 is connected to an external hanging object.
