Description

Technical Field

[0001] This invention belongs to the field of photovoltaic energy storage equipment technology, specifically relating to an integrated photovoltaic energy storage device that combines foldable storage, angle adjustment, convenient cleaning of the light-receiving surface, and protective functions. It is suitable for outdoor operations, emergency power supply, and residential distributed photovoltaic systems, as well as other scenarios requiring flexible deployment, efficient operation and maintenance, and equipment protection. Background Technology

[0002] With the popularization of photovoltaic technology, photovoltaic energy storage devices are increasingly widely used because they can integrate light energy capture and storage. However, existing devices still have many pain points:

[0003] Poor storage and portability: Traditional photovoltaic panels are mostly fixed rigid structures, which are large in size and heavy in weight, making them inconvenient to move and store, especially in outdoor temporary power supply or space-limited scenarios where they are not adaptable enough; although some foldable photovoltaic panels can be folded, the folding structure is simple, and they still take up a lot of space after folding, and the unfolding / folding process is cumbersome.

[0004] Inconvenient angle adjustment: The power generation efficiency of photovoltaic panels is closely related to the angle of sunlight, but the angle adjustment mechanism of existing adjustable photovoltaic devices is mostly independently designed and separated from the folding structure. The adjustment process is complicated and the stability after adjustment is insufficient. It is easily affected by the external environment (such as wind) and the angle will shift. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated photovoltaic energy storage device and its usage method, to solve the problem of inconvenient storage and transportation of existing devices mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: an integrated photovoltaic energy storage device, including a U-shaped support, with vertical plates hinged to both the front and rear sides inside the U-shaped support, and three-fold photovoltaic panels hinged to both the left and right sides between the two vertical plates. The output end of the three-fold photovoltaic panels is electrically connected to a battery, which is installed on the bottom surface of the inner wall of the U-shaped support. U-shaped drive rails are hinged to the lower ends of both the left and right sides of the vertical plates.

[0006] The upper ends of both sides of the vertical plate are hinged with a first main drive rod. The first main drive rod is inside the U-shaped drive slide rail. The end of the first main drive rod away from the vertical plate is hinged with a second main drive rod. The end of the second main drive rod away from the first main drive rod is hinged with a third main drive rod. One end of the third main drive rod is hinged to a component plate of the three-fold photovoltaic panel away from the vertical plate.

[0007] Limiting grooves are provided on both the left and right sides of the vertical plate. The two limiting grooves are connected. A first driven rod is slidably arranged in the limiting groove. The middle part of the first driven rod is hinged in the hinge groove of the middle part of the first main driven rod. A second driven rod is hinged to the end of the first driven rod away from the vertical plate. The hinge shaft end of the second driven rod and the first driven rod is slidably arranged on the inner wall of the U-shaped drive rail.

[0008] The middle part of the second driven rod is hinged to the middle part of the second main driven rod, and the end of the second driven rod away from the first driven rod is hinged to a component plate of the three-fold photovoltaic panel away from the vertical plate.

[0009] The first main drive rod, the second main drive rod, the third main drive rod, the first driven drive rod, the second driven drive rod, and a component plate of the three-fold photovoltaic panel form a parallelogram folding structure, which is used to drive the three-fold photovoltaic panel to unfold into a flat state or fold into a Z-shape.

[0010] Preferably, a hinge rod is also hinged at the hinge joint between the first main drive rod and the second main drive rod, with the end of the hinge rod away from the first main drive rod hinged to the lower side of the inner wall of the U-shaped drive slide rail.

[0011] Preferably, a hinge plate is hinged to the first main drive rod, and the end of the hinge plate away from the first main drive rod is hinged to the inner wall of the U-shaped drive slide rail.

[0012] Preferably, the inner wall of the U-shaped support is provided with guide grooves on both the front and rear sides. The guide grooves are composed of vertical grooves and arc grooves. The vertical grooves are vertically set below the vertical plate, and the center of the arc grooves is at the hinge point between the vertical plate and the U-shaped support. A slider is slidably connected in the guide grooves. Arc rods with alternating arrangement on both sides are rotatably sleeved on the sliders. The ends of the arc rods away from the sliders are respectively hinged to the outer sides of two U-shaped drive rails on the same side.

[0013] The outer side of the slider is fitted with a slide rail drive plate. One end of the slide rail drive plate is fixedly connected to a drive rod. The drive rod is rotatably connected to a connecting frame fixed inside the U-shaped support. A worm wheel is fixedly fitted in the middle of the drive rod. A worm is meshed on the worm wheel. One end of the worm is rotatably connected to the connecting frame.

[0014] When the slider slides along the vertical groove of the guide groove, it drives the three-fold photovoltaic panel to unfold or fold. When it slides along the arc groove, it drives the unfolded three-fold photovoltaic panel to adjust the tilt angle.

[0015] Preferably, protrusions are inserted into the opposite sides of the two vertical plates, the protrusions are located between the two limiting grooves, and spring telescopic rods are fixedly connected to the protrusions, with the other end of the spring telescopic rods fixed to the outer wall of the vertical plates.

[0016] The U-shaped support has an arc-shaped protrusion plate that overlaps with the protrusion on its inner side.

[0017] Preferably, spring telescopic plates are fixedly connected to the two component plates of the three-fold photovoltaic panel closest to the vertical plate. The two spring telescopic plates are in contact with each other, and the spring telescopic plates are used to assist the two component plates of the three-fold photovoltaic panel in folding and storage through reaction force.

[0018] Preferably, when the two sets of three-fold photovoltaic panels are folded and stored, they gradually tilt from a horizontal state to a vertical state.

[0019] A method for using an integrated photovoltaic energy storage device includes the following steps:

[0020] S1. When unfolding, rotate the worm gear to drive the worm wheel, causing the drive rod to rotate counterclockwise, which in turn drives the slider in the slide rail drive plate to move down along the vertical groove of the guide slide.

[0021] The slider pulls two U-shaped drive rails through the interlaced arc rods on both sides, causing them to deflect and unfold in a V-shape. This causes the hinge axis of the first driven rod and the second driven rod to slide within the U-shaped drive rails. At the same time, one end of the first driven rod moves upward along the limiting groove, cooperating with the deflection of the first main drive rod. This causes the parallelogram structure composed of the first main drive rod, the second main drive rod, the third main drive rod, the first driven rod, the second driven rod, and the three-fold photovoltaic panel to extend, thus unfolding the three-fold photovoltaic panel into a flat plate.

[0022] S2. After unfolding, the slider enters the arc groove of the guide slide (the center of the circle is the hinge point between the vertical plate and the U-shaped support), which drives the arc rod and the U-shaped drive slide rail to deflect, so that the three-fold photovoltaic panel tilts to the set angle.

[0023] At this time, the protrusion on the vertical plate slides along the arc-shaped protrusion and resets, locking into the first driven rod in the horizontal state, enhancing the structural strength. The three-fold photovoltaic panel absorbs light energy and stores it in the battery.

[0024] S3. When storing, rotate the worm gear in the opposite direction. The slider first resets along the arc groove to make the three-fold photovoltaic panel horizontal. The protrusion rebounds under the action of the spring telescopic rod.

[0025] The slider then moves upward along the vertical groove, pushing the U-shaped drive rail to close. Through the linkage of the drive rod, the three-fold photovoltaic panel is folded into a Z-shape. The spring telescopic plate assists in the folding and protects the sunlit surface, completing the storage.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] This invention offers convenient folding and storage, while also ensuring cleanliness and protection, and maximizing space utilization. Through a Z-shaped folding design of a three-fold photovoltaic panel, combined with a linkage structure consisting of a U-shaped drive rail and a master-slave drive rod, the photovoltaic panel can be quickly unfolded and folded. The folded size is significantly reduced, facilitating transportation and storage, making it particularly suitable for outdoor mobile applications. This solves the problems of traditional photovoltaic panels being large and lacking portability.

[0028] This invention features an adjustable angle and optimized power generation efficiency. Utilizing the synergistic effect of guide grooves (vertical groove + arc groove), sliders, and arc rods, after the photovoltaic panel is fully unfolded, the drive mechanism can drive the vertical plate and the unfolded photovoltaic panel to deflect around the hinge point, flexibly adjusting the tilt angle to ensure that the photovoltaic panel always maintains the optimal angle of sunlight, significantly improving power generation efficiency.

[0029] This invention features a stable structure and long service life. The addition of a hinge rod reduces the forward and backward swaying of the second main drive rod, while the hinge plate enhances the connection strength between the first main drive rod and the U-shaped drive rail. Simultaneously, during the deflection of the vertical plate, the protrusion and the arc-shaped protrusion plate cooperate to restrict the deflection of the first driven drive rod, further strengthening the structural stability in the unfolded state, effectively resisting external impacts, and extending the service life of the device.

[0030] This invention features an auxiliary structure that enhances operational smoothness. The spring-loaded telescopic plate assists in the reset of the photovoltaic panel assembly during folding through a reaction force, while the spring-loaded telescopic rod automatically resets the protrusions, reducing manual operation intensity and making the unfolding / folding process smoother and more efficient. Furthermore, when the three-fold photovoltaic panel is fully folded, none of its light-receiving surfaces are exposed, further strengthening the device's protection of the light-receiving surfaces of the three-fold photovoltaic panel.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1 to 8 This invention provides a technical solution: an integrated photovoltaic energy storage device, including a U-shaped support 1, with vertical plates 2 hinged to both the front and rear sides inside the U-shaped support 1, and three-fold photovoltaic panels 4 hinged to both the left and right sides between the two vertical plates 2. The output end of the three-fold photovoltaic panels 4 is electrically connected to a battery 5, and the battery 5 is installed on the bottom surface of the inner wall of the U-shaped support 1. The three-fold photovoltaic panels 4 can be folded in a Z-shape. The lower ends of the left and right sides of the vertical plates 2 are hinged to U-shaped drive rails 3. When the two sets of three-fold photovoltaic panels 4 are folded and stored, they gradually tilt from horizontal to vertical. This makes it convenient for users to clean the sunlit surface of the three-fold photovoltaic panels 4 before completely storing them.

[0042] The upper ends of both sides of the vertical plate 2 are hinged with a first main drive rod 31, and the first main drive rod 31 is inside the U-shaped drive slide rail 3. The end of the first main drive rod 31 away from the vertical plate 2 is hinged with a second main drive rod 32, and the end of the second main drive rod 32 away from the first main drive rod 31 is hinged with a third main drive rod 33. One end of the third main drive rod 33 is hinged on a component plate of the three-fold photovoltaic panel 4 away from the vertical plate 2.

[0043] Limiting grooves 34 are provided on both the left and right sides of the vertical plate 2, and the two limiting grooves 34 are connected. A first driven rod 35 is slidably arranged in the limiting groove 34. The middle part of the first driven rod 35 is hinged in the hinge groove of the middle part of the first main drive rod 31. The end of the first driven rod 35 away from the vertical plate 2 is hinged to a second driven rod 36. The hinge shaft end of the second driven rod 36 and the first driven rod 35 is slidably arranged on the inner wall of the U-shaped drive rail 3.

[0044] The middle part of the second driven rod 36 is hinged to the middle part of the second main driven rod 32. The middle part of the second driven rod 36 is provided with a through groove. The second driven rod 36 is hinged to the middle part of the second main driven rod 32 through the through groove. The end of the second driven rod 36 away from the first driven rod 35 is hinged to a component plate of the three-fold photovoltaic panel 4 away from the vertical plate 2.

[0045] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, a hinge rod 37 is also hinged at the hinge joint between the first main drive rod 31 and the second main drive rod 32. The end of the hinge rod 37 away from the first main drive rod 31 is hinged to the lower side of the inner wall of the U-shaped drive slide rail 3. The hinge rod 37 is used to reduce the back-and-forth swaying of the second main drive rod 32.

[0046] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, a hinge plate 38 is hinged to the first main drive rod 31, and the end of the hinge plate 38 away from the first main drive rod 31 is hinged to the inner wall of the U-shaped drive slide rail 3. The hinge plate 38 increases the connection strength between the first main drive rod 31 and the U-shaped drive slide rail 3.

[0047] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, guide grooves 6 are provided on both the front and rear sides of the inner wall of the U-shaped support 1. The guide grooves 6 are composed of vertical grooves and arc grooves. The vertical grooves are vertically set below the vertical plate 2, and the center of the arc grooves is at the hinge point between the vertical plate 2 and the U-shaped support 1. A slider 61 is slidably connected in the guide groove 6. Arc rods 62 with alternating sides are rotatably sleeved on the slider 61. The ends of the arc rods 62 away from the slider 61 are respectively hinged to the outer sides of two U-shaped drive rails 3 on the same side. When the slide rail drive plate 63 drives the slider 61 to move down in the vertical groove of the guide groove 6, the slider 61 slides simultaneously inside the slide rail drive plate 63.

[0048] A slide rail drive plate 63 is slidably sleeved on the outer side of the slider 61. A drive rod 64 is fixedly connected to one end of the slide rail drive plate 63. The drive rod 64 is rotatably connected to the connecting frame 65 fixed inside the U-shaped support 1. A worm gear 66 is fixedly sleeved in the middle of the drive rod 64. A worm 67 is meshed on the worm gear 66. One end of the worm 67 is rotatably connected to the connecting frame 65.

[0049] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, protrusions 7 are inserted into the opposite sides of the two vertical plates 2. The protrusions 7 are located between the two limiting grooves 34. A spring telescopic rod 71 is fixedly connected to the protrusions 7. The other end of the spring telescopic rod 71 is fixed to the outer wall of the vertical plate 2.

[0050] An arc-shaped protrusion 72 that overlaps with the protrusion 7 is fixedly connected to the inner side of the U-shaped support 1.

[0051] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, spring telescopic plates 8 are fixedly connected to the two component plates of the three-fold photovoltaic panel 4 near the vertical plate 2, and the two spring telescopic plates 8 are in contact with each other. When the device folds and stores the three-fold photovoltaic panel 4, the reaction force between the two spring telescopic plates 8 assists in the folding and storage of the two component plates of the three-fold photovoltaic panel 4 near the vertical plate 2. When the three-fold photovoltaic panel 4 is folded, the light-receiving surface of the three-fold photovoltaic panel 4 is not exposed to the outside, further enhancing the protection of the light-receiving surface of the three-fold photovoltaic panel 4 by the device.

[0052] The method of use and advantages of this invention: The working process of this photovoltaic energy storage integrated device is as follows:

[0053] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, when the device is in use, the worm gear 67 drives the drive rod 64 on the worm wheel 66 to rotate counterclockwise, which drives the slider 61 in the slide rail drive plate 63 to slide down in the vertical groove of the guide slide groove 6. During the downward movement of the slider 61, it drives the two arc rods 62 on it to move down and causes the two U-shaped drive slide rails 3 hinged at their upper ends to deflect and unfold in a V-shape.

[0054] During the deflection of the U-shaped drive slide rail 3, the hinge shaft of the first driven drive rod 35 and the second driven drive rod 36 is pulled to slide within the U-shaped drive slide rail 3, causing one end of the first driven drive rod 35 to slide upward within the limiting slide groove 34.

[0055] Furthermore, when the first driven rod 35 slides within the limiting groove 34, it pulls the lower end of the first main drive rod 31 to deflect away from the vertical plate 2.

[0056] At this time, the first main drive rod 31 and the first driven drive rod 35 deflect simultaneously, causing the first main drive rod 31, the second main drive rod 32, the third main drive rod 33, the first driven drive rod 35, the second driven drive rod 36, and one of the component plates of the three-fold photovoltaic panel 4 to extend into a parallelogram folding structure, causing the component plate of the three-fold photovoltaic panel 4 that is farthest from the vertical plate 2 to pull the remaining two component plates to unfold.

[0057] When the three-fold photovoltaic panel 4 is fully unfolded and forms a flat plate, the first driven rod 35 is in a horizontal state. At this time, the worm gear 67 drives the worm wheel 66 to drive the slider 61 to slide in the arc groove of the guide groove 6. This causes the arc rod 62 and the two U-shaped drive rails 3 at its ends to deflect around the hinge point where the lower end of the vertical plate 2 is connected to the U-shaped support 1, causing the unfolded three-fold photovoltaic panel 4 to tilt at a certain degree. This allows the user to set the tilt angle of the three-fold photovoltaic panel 4 according to their needs for solar energy storage.

[0058] Furthermore, during the deflection of the vertical plate 2, the protrusion 7 slides on the arc-shaped protrusion 72, causing the protrusion 7 to move inward into the vertical plate 2 between the two first driven rods 35 in a horizontal state, further restricting the deflection of the first driven rods 35 and strengthening the strength of the three-fold photovoltaic panel 4 after it is unfolded.

[0059] After the device is used, the worm gear 67 is rotated in the opposite direction to drive the slider 61 to slide in the arc groove of the guide groove 6, so that the unfolded three-fold photovoltaic panel 4 deflects and resets to a horizontal state. At this time, the protrusion 7 is reset under the action of the extension of the spring telescopic rod 71, and the restriction on the first driven rod 35 is released.

[0060] After the slider 61 enters the vertical groove within the arc groove of the guide groove 6, the worm gear 67 continues to rotate. The arc rod 62 moves upward, pushing the two U-shaped drive rails 3 to deflect and close. During the deflection and closure of the two U-shaped drive rails 3, one end of the first driven rod 35 moves downward and slides within the limiting groove 34. This, in conjunction with the second main drive rod 32, the third main drive rod 33, and the second driven rod 36, pulls the three-fold photovoltaic panel 4 to fold and store.

[0061] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
