Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides, for example Figures 1-8 The foldable solar energy storage backpack shown includes a front half-pack 1, a rear half-pack 2 connected to the lower rear end of the front half-pack 1, and the rear half-pack 2 located directly behind the front half-pack 1. A zipper 3 is provided between the front half-pack 1 and the rear half-pack 2. A handle 4 is provided at the upper end of the rear half-pack 2. Shoulder straps 5 are provided on both the left and right sides of the rear end of the rear half-pack 2. A photovoltaic module is provided inside the upper front end of the front half-pack 1. A folding component is connected to the lower end of the photovoltaic module. Multiple output interfaces 6 are provided inside the upper end of the front half-pack 1. The multiple output interfaces 6 are electrically connected to the photovoltaic module through a wiring harness. The energy storage backpack generates and stores electricity through the photovoltaic module and outputs the stored electricity to the outside through the multiple output interfaces 6. The energy storage backpack can be worn on the back with two shoulder straps 5 and carried by hand with the handle 4. The front half-pack 1 and the rear half-pack 2 of the energy storage backpack can be closed and opened with the zipper 3 and can store items inside.

[0031] Preferably, the photovoltaic module includes an upper limit frame 7, a photovoltaic panel 8, and an energy storage box 9. The upper limit frame 7 is snapped into the upper side of the front half of the package 1. The photovoltaic panel 8 is installed inside the upper limit frame 7, and the upper sides of the left and right ends of the photovoltaic panel 8 are rotatably connected to the upper limit frame 7 through folding hinges and folding holes. The two folding hinges are fixedly connected to the upper sides of the left and right ends of the photovoltaic panel 8, and the two folding holes are respectively opened on the inner walls of the upper sides of the left and right ends of the upper limit frame 7. The photovoltaic panel 8 of the photovoltaic module can generate electrical energy through sunlight. Since the energy storage box 9 is composed of a junction box and an energy storage battery, the electrical energy generated by the photovoltaic panel 8 can be stored in the energy storage battery through the junction box. The energy storage battery can then supply power to multiple output interfaces 6 through the junction box.

[0032] In the process of photovoltaic module power generation and energy storage, it can be rotated and unfolded and folded up inside the upper limit frame 7 through the folding pivot and folding hole, and the unfolding angle can be adjusted according to the angle of illumination.

[0033] Preferably, the folding assembly includes a folding sleeve 11, a folding rod 12, an air duct 15, and an air filling / deleting cylinder 16. A lower limit frame 10 is connected to the lower center of the upper limit frame 7, and the lower limit frame 10 is snapped into the lower side of the front half of the front half of the pack 1. The folding sleeve 11 is disposed inside the lower limit frame 10, and the lower sides of both ends of the folding sleeve 11 are rotatably connected to the folding rod 12 through connecting shafts and connecting holes. The two connecting shafts are respectively fixedly connected to the lower sides of the left and right ends of the folding sleeve 11, and the two connecting holes are respectively opened in the folding sleeve 11. The folding rod 12 is inserted into the lower inner wall of the left and right ends of the folding sleeve 11. The upper end of the folding rod 12 is rotatably connected to the center of the lower end of the photovoltaic panel 8. The lower end of the folding rod 12 is fixedly connected to a push-pull valve head 13, which is slidably connected inside the folding sleeve 11 and is sealed with a rubber sealing ring. A retraction spring 14 is provided outside the folding rod 12, located above the push-pull valve head 13 and inside the folding sleeve 11. The lower limit frame 10 is located on the right side. A vent pipe 15 is connected to the lower side of the front half-pack 1, and the vent pipe 15 communicates with the connecting pivot hole on the right side. It is located inside the outer wall of the front half-pack 1. The connecting pivot on the right side is hollow, and the vent pipe 15 communicates with the inside of the folding sleeve 11 through the connecting pivot hole and the connecting pivot on the right side. The other end of the vent pipe 15 is connected to an air inlet / outlet cylinder 16, which is located inside the lower right corner of the rear end of the rear half-pack 2 and extends into the inside of the front half-pack 1. During the unfolding and retraction of the photovoltaic module, the air inlet / outlet cylinder 16 can vent through the vent pipe. The tube 15 inflates and deflates the folding sleeve 11. When inflating, the gas inside the folding sleeve 11 overcomes the elastic force of the retracting spring 14 and pushes up the push-pull valve head 13, causing the push-pull valve head 13 to drive the folding rod 12 to slide inside the folding sleeve 11 and push the photovoltaic panel 8 to unfold from inside the upper limit frame 7. Conversely, when deflating, the retracting spring 14 pushes the push-pull valve head 13 downward, causing the push-pull valve head 13 to drive the folding rod 12 to slide into the folding sleeve 11 and pull the photovoltaic panel 8 to retract into the upper limit frame 7.

[0034] The inflation / deflation cylinder 16 has multiple air holes on its outer rear end. A limiting ring 17 is installed inside the front end of the inflation / deflation cylinder 16 and is fixedly connected to the inner wall of the cylinder, located behind the connection between the air guide pipe 15 and the inflation / deflation cylinder 16. An inflation valve head 18 is installed at the rear end of the limiting ring 17 and is slidably connected inside the inflation / deflation cylinder 16. A rubber sealing ring is installed between the valve head 18 and the cylinder. A push-pull tube 19 is connected to the center of the rear end of the inflation valve head 18, and the opening at the front end of the push-pull tube 19 extends through for inflation. The valve head 18 is internal and communicates with the interior of the inflation / deflation cylinder 16. The rear end of the push-pull tube 19 extends to the exterior of the rear end of the inflation / deflation cylinder 16. A pressure spring 20 is installed on the exterior of the push-pull tube 19, located at the rear end of the inflation valve head 18 and inside the inflation / deflation cylinder 16. A push-pull head 21 is connected to the rear end of the push-pull tube 19 and communicates with the interior of the push-pull head 21, which is located outside the inflation / deflation cylinder 16. An air inlet / outlet hole 22 is opened at the center of the rear end of the push-pull head 21. A sealing head 23 is slidably connected inside the push-pull head 21. Multiple air holes are provided on the inner and outer sides of the plug 23. A venting rod 24 is fixedly connected to the center of the rear end of the plug 23. The venting rod 24 passes through the inside of the air inlet / outlet hole 22 and extends to the outside of the rear end of the air inlet / outlet hole 22. A sealing spring 25 is provided at the rear end of the plug 23, and the sealing spring 25 is located inside the push-pull head 21. During the process of the air cylinder 16 inflating the folding sleeve 11, the air inflation valve head 18 is quickly pulled back and forth by the push-pull tube 19 and the push-pull head 21. When the push-pull tube 19 and the push-pull head 21 are pulled back quickly, The push-pull tube 19 drives the inflation valve head 18 to slide backward inside the inflation / deflation cylinder 16. At this time, due to the rapid backward movement of the inflation valve head 18, an instantaneous negative pressure is generated inside the inflation / deflation cylinder 16. This negative pressure draws the sealing head 23 backward, allowing the sealing head 23 to overcome the elastic force of the sealing spring 25 and slide forward inside the push-pull head 21. Simultaneously, gas enters the push-pull head 21 through multiple air holes on the outer side of the sealing head 23, and then is introduced into the inflation / deflation cylinder 16 through the push-pull tube 19, thereby allowing the inflation / deflation cylinder 16 to draw in external gas.

[0035] When the push-pull tube 19 and the push-pull head 21 are pushed forward quickly, the inflation valve head 18 is pushed forward through the push-pull tube 19 and slides forward inside the inflation / deflation cylinder 16, squeezing the gas drawn into the inflation / deflation cylinder 16 into the air guide tube 15. The air spring 20 assists in squeezing the gas. At this time, the inflation / deflation cylinder 16 is squeezed into the folding sleeve 11 through the air guide tube 15, thereby lifting the push-pull valve head 13 inside the folding sleeve 11 and unfolding the photovoltaic panel 8.

[0036] Furthermore, when venting the inside of the folding sleeve 11, by pressing and holding the venting lever 24, the venting lever 24 overcomes the elastic force of the sealing spring 25 and slides forward inside the push-pull head 21. At this time, the push-pull valve head 13 slides downward inside the folding sleeve 11 under the action of the retracting spring 14, and pushes the gas inside the folding sleeve 11 into the air guide tube 15, and then pushes it into the inflation / deflation cylinder 16 through the air guide tube 15. The gas pushed into the inflation / deflation cylinder 16 is discharged through the push-pull tube 19 and multiple air holes and inlet / outlet holes 22 on the inside and outside of the sealing head 23, so that the folding rod 12 can slide smoothly into the folding sleeve 11, and the photovoltaic panel 8 can be retracted smoothly.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
