[0023] The photovoltaic panels on photovoltaic energy supply equipment are mostly fixed to the equipment and cannot be stored, resulting in a large overall size of the equipment.

[0026] Example 1: By Figure 1-6As can be seen, a portable photovoltaic energy supply device comprises a housing 1, a photovoltaic panel 2, a battery 3, and an interface 5. The housing 1 houses the photovoltaic panel 2 and the battery 3. An interface 5 is fixedly connected to the lower front of the housing 1. It is worth noting that the photovoltaic panel 2 and the battery 3 are connected via a transformer, enabling the conversion of solar energy into electrical energy and its storage. The specific model is not limited, as long as it meets the actual usage requirements. This technology is well-known to those skilled in the art and will not be elaborated upon here. The interface 5 is used to connect external electrical appliances. The portable photovoltaic energy supply device also includes a storage device 4 and a protective shield.

The storage device 4 is disposed on the side wall of the outer shell 1; the protective device 6 is disposed on the outside of the outer shell 1; and the support device 7 is disposed below the photovoltaic panel 2. When the entire equipment is transported and carried, the photovoltaic panel 2 is stored in the outer shell 1 by the storage device 4, and the photovoltaic panel 2 is supported by the support device 7 during use to improve the stability of the photovoltaic panel 2. The interface 5 that is no longer in use is protected by the protective device 6. The storage device 4 stores the photovoltaic panel 2 to reduce the overall volume of the equipment, the protective device 6 protects the interface 5, and the support device 7 supports the photovoltaic panel 2 during use.

[0027] In the specific implementation process, it is worth noting that the outer casing 1, photovoltaic panel 2, battery 3, and interface 5 constitute a photovoltaic energy supply device. It is worth explaining that the photovoltaic panel 2 and the battery 3 are connected through a transformer, which can convert light energy into electrical energy and store the electrical energy. The specific model is not limited, as long as it meets the actual use. This technology is known to those skilled in the art and will not be described in detail here. The interface 5 is used to connect external electrical appliances. When the whole device is moved and carried, the photovoltaic panel 2 is stored in the outer casing 1 by the storage device 4. The photovoltaic panel 2 is supported by the support device 7 during use to improve the stability of the photovoltaic panel 2. The interface 5 is protected by the protective device 6 when it is no longer in use.

[0028] Specifically, the outer casing 1, photovoltaic panel 2, battery 3, and interface 5 constitute a photovoltaic energy supply device. It is worth noting that the photovoltaic panel 2 and the battery 3 are connected through a transformer, which can convert light energy into electrical energy and store the electrical energy. The specific model is not limited, as long as it meets the actual use. This technology is known to those skilled in the art and will not be described in detail here. The interface 5 is used to connect external electrical appliances. When the whole device is moved and carried, the photovoltaic panel 2 is stored in the outer casing 1 by the storage device 4. The photovoltaic panel 2 is supported by the support device 7 during use to improve the stability of the photovoltaic panel 2. The interface 5 is protected by the protective device 6 when it is no longer in use.

[0029] Example 2: From Figure 1-6It is known that the storage device 4 includes a housing 41, a worm gear 42, a handwheel 43, a worm wheel 44, a column 45, a connecting plate 46, a frame 47, a guide part 48, and an auxiliary part 49. The housing 41 is fixed to the side wall of the outer shell 1; both ends of the worm gear 42 are rotatably connected to the inner wall of the housing 41 through bearings, and both ends extend to the outside of the housing 41; the handwheel 43 is fixedly connected to one end of the worm gear 42; when the photovoltaic panel 2 needs to be stored, the user pushes the frame 47, and the frame 47 drives... The photovoltaic panel 2 returns to the outer casing 1. Then, the user turns the handwheel 43, which drives the worm gear 42 to rotate. The threads on both sides of the worm gear 42 are in opposite directions. There are two worm wheels 44, both meshing and connected above the worm gear 42. The worm gear 42 drives the worm wheels 44 to rotate, and both are rotatably connected to the inner wall of the housing 41 via pins. There are two columns 45, each fixedly connected to the top of one of the two worm wheels 44. The two worm wheels 44 drive the columns 45 to rotate, and one end extends to the top of the housing 41. There are two connecting plates 46, each fixedly connected to the upper side wall of the column 45. The two columns 45 drive the connecting plates 46 to rotate, rotating the connecting plates 46 90 degrees, so that the connecting plates 46 contact the outer wall of the frame 47, fixing the position of the frame 47. After completion, the user stops turning the handwheel 43. When using the photovoltaic panel 2, the user turns the handwheel 43 in the opposite direction, and the connecting plates 46 leave the frame 47, releasing the frame 47. The frame 47 is pulled out of the outer shell 1 to expose the photovoltaic panel 2. The outer wall of the frame 47 is attached to the side wall of the connecting plate 46 and inserted into the inside of the outer shell 1. The guide part 48 is provided on the outer wall of the frame 47. The auxiliary part 49 is provided on the outside of the frame 47. When the frame 47 is pushed back into the outer shell 1, the worm gear 42 is driven by the handwheel 43 to make the worm wheel 44 drive the column 45 to move, so that the connecting plate 46 is attached to the outer wall of the frame 47.

[0030] In the specific implementation process, it is worth noting that when it is necessary to store the photovoltaic panel 2, the user pushes the frame 47, which drives the photovoltaic panel 2 back into the outer shell 1. Then, the user turns the handwheel 43, which drives the worm gear 42 to rotate. The threads on both sides of the worm gear 42 are in opposite directions, which drives the worm wheel 44 to rotate. The two worm wheels 44 drive the column 45 to rotate, and the two columns 45 drive the connecting plate 46 to rotate, rotating the connecting plate 46 by 90 degrees, so that the connecting plate 46 contacts the outer wall of the frame 47, fixing the position of the frame 47. After that, the user stops turning the handwheel 43. When using the photovoltaic panel 2, the user turns the handwheel 43 in the opposite direction, and the connecting plate 46 leaves the frame 47, releasing the fixing of the frame 47. The frame 47 is then pulled out of the outer shell 1, thus exposing the photovoltaic panel 2 and realizing the storage of the photovoltaic panel 2.

[0031] Furthermore, the guide part 48 includes a slide groove 481 and a slider 482. The slide groove 481 is formed on the inner wall of the outer casing 1. The slider 482 is fixedly connected to the outer wall of the frame 47 and slidably engaged with the inner wall of the slide groove 481. When the frame 47 moves, the frame 47 drives the slider 482 to move, and the slider 482 moves in the slide groove 481. The slider 482 slides in the slide groove 481 under the drive of the frame 47.

[0032] In the specific implementation process, it is worth noting that when the frame 47 moves, the frame 47 drives the slider 482 to move. The slider 482 moves in the slide groove 481 to guide the frame 47 and prevent the frame 47 from shaking or deviating.

[0033] Furthermore, the auxiliary part 49 includes a handle 491 and a lifting handle 492. The handle 491 is fixedly connected to the side of the frame 47 near the connecting plate 46. When the user moves the frame 47, the user holds the handle 491 to push or pull the handle 491, which moves the frame 47, making it convenient for the user to move the frame 47. There are two lifting handles 492, which are fixedly connected to the top front and the top back of the outer casing 1, respectively. The user holds the lifting handles 492 on both sides to move the outer casing 1, thereby allowing the user to carry the entire device. The handle 491 moves the frame 47, and the lifting handles 492 move the outer casing 1.

[0034] In the specific implementation process, it is worth noting that when the user moves the frame 47, the user holds the handle 491, thereby pushing or pulling the handle 491, which drives the frame 47 to move, making it convenient for the user to move the frame 47. The user holds the handles 492 on both sides, thereby driving the outer shell 1 to move, so that the user can move the entire equipment.

[0035] Furthermore, the support device 7 includes a connecting column 71, a bolt 72, a threaded hole 73, and a support rod 74. The end of the connecting column 71 is rotatably connected to the inner wall of the frame 47 via a pin. When the photovoltaic panel 2 is in use, the user pulls the frame 47 out of the outer casing 1. At this time, the connecting column 71 rotates in a circle around the pin, and the connecting column 71 protrudes from the top of the frame 47. The support rod 74 is sleeved on the inner wall of the connecting column 71. The threaded hole 73 is formed on the surface of the support rod 74. After completion, the user rotates the bolt 72, and the bolt 72 moves out of the current threaded hole 73. After completion, the user moves the support rod 74. When the support rod 74 is in the connecting column 71, the length of the support rod 74 is adjusted. After completion, the user rotates the bolt 72 again. This allows the bolt 72 to be rotated into the corresponding threaded hole 73, bringing the bottom of the support rod 74 into contact with the ground and supporting the photovoltaic panel 2. The bolt 72 is threaded to the inner wall of the connecting column 71 and the inner wall of the threaded hole 73, respectively. When storing, the user moves the length of the support rod 74 back to its original length, rotates the connecting column 71 back into the bottom of the frame 47, and then pushes the frame 47 into the outer shell 1. At this time, the right end of the connecting column 71 contacts the outer opening of the right end of the outer shell 1 to prevent the connecting column 71 from falling into the outer shell 1. When the photovoltaic panel 2 is in use, the frame 47 is supported by the cooperation of the connecting column 71 and the support rod 74, and the length of the support rod 74 is adjusted by the threaded hole 73 and the bolt 72.

[0036] In the specific implementation process, it is worth noting that when the photovoltaic panel 2 is in use, the user pulls the frame 47 out of the outer shell 1. At this time, the connecting post 71 rotates in a circular motion around the pin, and the connecting post 71 protrudes from the top of the frame 47. After that, the user rotates the bolt 72, and the bolt 72 leaves the current threaded hole 73. After that, the user moves the support rod 74. When the support rod 74 is in the connecting post 71, the user adjusts the length of the support rod 74. After that, the user rotates the bolt 72 again, thereby rotating the bolt 72 into the corresponding threaded hole 73, so that the bottom of the support rod 74 contacts the ground to support the photovoltaic panel 2. When storing, the user moves the length of the support rod 74 back to its original length, rotates the connecting post 71 back into the bottom of the frame 47, and then pushes the frame 47 into the outer shell 1. At this time, the right end of the connecting post 71 contacts the outer opening of the right end of the outer shell 1 to prevent the connecting post 71 from falling into the outer shell 1, thus supporting the photovoltaic panel 2 in use.

[0037] Furthermore, the protective device 6 includes a hollow column 61, a horizontal column 62, a spring 63, a plug 64, a horizontal block 65, and a cover 66. The hollow column 61 is fixedly connected to the front of the outer shell 1; the horizontal column 62 is disposed above the hollow column 61; the two ends of the spring 63 are fixedly connected to the bottom of the horizontal column 62 and the top of the hollow column 61, respectively; when the interface 5 is not in use, the user pulls the horizontal column 62, which stretches the spring 63. The plug 64 is fixedly connected to the bottom of the horizontal column 62, passes through the hollow column 61, and is movably connected to the hollow column 61; the horizontal column 62 drives the plug 64 to move within the hollow column 61, thereby moving the plug 64 into the hollow column 61, and the cover 66. 66 is hinged to the lower front of the outer shell 1; the horizontal block 65 is fixedly connected to the top of the cover 66; after completion, the user rotates the cover 66, which drives the horizontal block 65 to rotate, rotating the horizontal block 65 to the bottom of the hollow column 61. At this time, the cover 66 fits against the outer shell 1, covering the interface 5. After completion, the user releases the horizontal column 62. At this time, the spring 63 rebounds, thereby inserting the plug 64 into the insertion hole on the surface of the horizontal block 65, fixing the position of the cover 66. Under the drive of the horizontal column 62, the plug 64 returns to the hollow column 61. By rotating the cover 66, the interface 5 is covered, and finally the plug 64 is inserted into the horizontal block 65.

[0038] In the specific implementation process, it is worth noting that when the interface 5 is not in use, the user pulls the horizontal column 62, which stretches the spring 63. The horizontal column 62 drives the insertion rod 64 to move in the hollow column 61, thereby moving the insertion rod 64 into the hollow column 61. After that, the user rotates the cover 66, which drives the horizontal block 65 to rotate, moving the horizontal block 65 to below the hollow column 61. At this time, the cover 66 fits against the outer shell 1, covering the interface 5. After that, the user releases the horizontal column 62. At this time, the spring 63 rebounds, thereby inserting the insertion rod 64 into the insertion hole on the surface of the horizontal block 65, fixing the position of the cover 66, and thus protecting the unused interface 5.

[0039] Specifically, when it is necessary to store the photovoltaic panel 2, the user first moves the support rod 74 back to its original length, rotates the connecting column 71 back into the bottom of the frame 47, and then pushes the frame 47 into the outer casing 1. The frame 47 drives the slider 482 to move, and the slider 482 moves in the groove 481. Then, the user turns the handwheel 43, which drives the worm gear 42 to rotate. The threads on both sides of the worm gear 42 are in opposite directions, and the worm gear 42 drives the worm wheel 44 to rotate. The two worm wheels 44 drive the column 45 to rotate. The two uprights 45 drive the connecting plate 46 to rotate, turning the connecting plate 46 ninety degrees, thereby bringing the connecting plate 46 into contact with the outer wall of the frame 47 and fixing the position of the frame 47. After this, the user stops turning the handwheel 43. Then, the user pulls the horizontal column 62, which stretches the spring 63. The horizontal column 62 drives the insert rod 64 to move within the hollow column 61, thus moving the insert rod 64 into the hollow column 61. After this, the user rotates the cover 66, which drives the horizontal block 65 to rotate, moving the horizontal block 65... 5. Rotate the device to the bottom of the hollow column 61. At this time, the cover 66 fits against the outer shell 1, covering the interface 5. After completion, the user releases the horizontal column 62. At this time, the spring 63 returns, allowing the insertion rod 64 to be inserted into the insertion hole on the surface of the horizontal block 65, fixing the position of the cover 66. The entire device can then be moved. After moving it to the outdoor location, the user rotates the handwheel 43 in the opposite direction, causing the connecting plate 46 to separate from the frame 47, releasing the fixation of the frame 47, and pulling the frame 47 out of the outer shell 1, thereby exposing the photovoltaic panel 2. Then, the connecting post 71 rotates in a circular motion around the pin, and the connecting post 71 protrudes from the top of the frame 47. After that, the user rotates the bolt 72, and the bolt 72 leaves the current threaded hole 73. After that, the user moves the support rod 74. When the support rod 74 is in the connecting post 71, the length of the support rod 74 is adjusted. After that, the user rotates the bolt 72 again, thereby rotating the bolt 72 into the corresponding threaded hole 73, so that the bottom of the support rod 74 contacts the ground and supports the photovoltaic panel 2.
