Figure 8 This is a schematic structural diagram of the positioning pin 32 and the limiting groove 42 in an unlocked state according to an embodiment of the present utility model.
[0027] like Figures 1 to 8As shown, in one specific embodiment, the photovoltaic sunshade 100 includes a support rod 40, an operating member 30, an umbrella body 10, a connecting member, and a locking structure 37. The support rod 40 has a vertically extending groove 41, and the operating member 30 has a slider 31 located within the groove 41 and capable of sliding along the groove 41. The umbrella body 10 includes a flexible umbrella surface 13, an umbrella support 12, a bracket 14, and a photovoltaic power generation module 11. One end of the umbrella support 12 is rotatably connected to the operating member 30, and the umbrella support 12 is connected to the bracket 14. The photovoltaic power generation module 11 is mounted on one side of the bracket 14, and the flexible umbrella surface 13 is mounted on the other side of the bracket 14. One end of the connecting rod 20 is rotatably connected to the support rod 40, and the other end is rotatably connected to the umbrella support 12. When the operating member 30 is subjected to an external force, the slider 31 slides along the groove 41, thereby causing the umbrella body 10 and the connecting rod 20 to rotate, thereby adjusting the tilt angle of the photovoltaic power generation module 11. The locking structure 37 connects the slide groove 41 of the support rod 40 and the operating member 30. The locking structure 37 is used to lock the operating member 30 when the photovoltaic power generation module 11 rotates to the target tilt angle. It can be understood that as the slider 31 slides along the slide groove 41, the tilt angle of the umbrella body 10 continuously changes. When it rotates to the target tilt angle, the locking structure 37 locks the slider 31, restricting it from continuing to slide. Here, the umbrella support 12 and the operating member 30 are connected by a hinge, and both ends of the connecting rod 20 are connected to the umbrella support 12 and the support rod 40 by hinges, respectively.
[0028] This embodiment allows adjustment of the tilt angle of the photovoltaic power generation module 11 based on the angle of sunlight by operating the operating component 30. This ensures that the light-receiving surface of the photovoltaic power generation module 11 remains nearly perpendicular to the sunlight, significantly improving the light intensity received by the photovoltaic power generation module 11 and thus increasing power generation efficiency. Furthermore, the locking structure 37 can lock the operating component 30, reliably locking the umbrella body 10 and preventing the photovoltaic power generation module 11 from shifting due to external forces or gravity. This improves the stability of the photovoltaic power generation module 11 at the target tilt angle and enhances power generation efficiency, while also increasing structural safety and ease of use.
[0029] In some embodiments, the operator can directly pull the operating component 30 to move the slider 31 up and down along the support rod 40. In other embodiments, the slider 31 can also be moved up and down by an automatic drive.
[0030] In some embodiments, the photovoltaic sunshade 100 further includes a base 50, on which a support rod 40 is mounted as the main load-bearing component. The internal groove 41 of the support rod 40 serves as a guide mechanism, guiding the slider 31. This embodiment ensures the overall stability of the photovoltaic sunshade 100 by installing the base 50. The operating component 30 acts as a drive unit, achieving vertical linear motion through the force applied by the operator. The connecting rod 20 converts the linear motion of the operating component 30 into the rotational motion of the umbrella support 12, thereby driving the photovoltaic power generation module 11 to rotate. When the operator pulls the operating component 30, the slider 31 on it moves vertically within the groove 41 of the support rod 40, causing the connecting rod 20 to rotate. The connecting rod 20 then causes the umbrella support 12 to rotate around the hinge axis with the operating component 30, thereby adjusting the tilt angle of the entire umbrella body 10.
[0031] In some embodiments, the locking structure 37 includes a positioning pin 32 and a plurality of limiting grooves 42 located within the slide groove 41. The plurality of limiting grooves 42 are arranged vertically at intervals on the support rod 40. The positioning pin 32 is located on the operating member 30 and has a locking state extending into the limiting groove 42 and an unlocking state disengaging from the limiting groove 42. See [reference needed] Figure 7 and Figure 8 This can be understood as follows: after the positioning pin 32 is pulled out of the limiting groove 42, the slider 31 can slide along the slide groove 41. When the positioning pin 32 is inserted into any of the limiting grooves 42, the slider 31 cannot slide along the slide groove 41. Here, each limiting groove 42 corresponds to a tilt angle. When the slider 31 moves into different limiting grooves 42, the tilt angle of the umbrella body 10 is different.
[0032] In some embodiments, the spacing between two adjacent limiting grooves 42 in the plurality of limiting grooves 42 is the same. In other embodiments, the spacing between two adjacent limiting grooves 42 in the plurality of limiting grooves 42 can also be designed to be different, depending on the design requirements.
[0033] In some embodiments, the number of limiting grooves 42 is 10. In other embodiments, the number of limiting grooves 42 can also be determined according to specific design requirements, such as 3, 5 or 8.
[0034] In some embodiments, the operating member 30 has a mounting hole extending along a first direction, the positioning pin 32 is mounted in the mounting hole, and has a pressing member 33. The locking structure 37 further includes an elastic member 34, which is sleeved on the positioning pin 32. Under the action of an external force, the positioning pin 32 moves along the first direction and disengages from the limiting groove 42, at which time the pressing member 33 compresses the elastic member 34. See [reference needed] Figure 8 When the external force is removed, the elastic element 34 returns to its elastic deformation, pushing the positioning pin 32 back into the limiting groove 42. (See below) Figure 7 Here, the first direction is... Figure 7The arrow points in the direction of the spring. Here, the elastic element 34 can be a spring, and the pressing element 33 can be a shaft. In other embodiments, the elastic element 34 can also be a component with the same properties as a spring.
[0035] Specifically, the mounting hole passes through the slider 31, and the slider 31 has a mounting groove 311 inside. The mounting groove 311 is located on the periphery of the mounting hole, and the elastic element 34 is installed in the mounting groove 311.
[0036] In some embodiments, the operating member 30 has an operating space 361, and the operating end 321 of the positioning pin 32 is located within the operating space 361. The operating end 321 has a pull ring 35. The operator can insert their finger into the operating space 361 and pull the pull ring 35 to pull the positioning pin 32 out of the limiting groove 42. At this time, the pressing member 33 squeezes the elastic member 34, so that the elastic member 34 is in a compressed state. Then, the operating member 30 is pushed to drive the operating member 30 to slide along the slide groove 41. When the operating member 30 moves into place, that is, when it drives the umbrella body 10 to rotate to the position of the limiting groove 42 corresponding to the target tilt angle, the positioning pin 32 is released. At this time, the elastic member 34 pushes the pressing member 33 to drive the positioning pin 32 to insert into the corresponding limiting groove 42, thereby achieving the effect of fixing the umbrella body 10.
[0037] In some embodiments, the operating member 30 includes a handle 36 connected to the slider 31. The handle 36 is located outside the slide groove 41 and has an operating space 361. The operator pulls the handle 36 to move the slider 31 up and down along the slide groove 41. Here, the handle 36 is hinged to the umbrella holder 12.
[0038] In some embodiments, when the positioning pin 32 is inserted into the lowermost limiting groove 42, the umbrella body 10 is in a vertical position relative to the ground. When the positioning pin 32 is inserted into the uppermost limiting groove 42, the umbrella body 10 is in a horizontal position. See [reference needed]. Figure 5 The tilt angle of the umbrella 10 can be adjusted according to the sunlight at different times.
[0039] In some embodiments, the pivot point between the connecting rod 20 and the support rod 40 is located above the operating member 30. In other embodiments, the pivot point may be designed according to specific requirements.
[0040] Figure 9 This is a schematic structural diagram of a photovoltaic sunshade 100 in a retracted state according to an embodiment of the present invention. Figure 9 As shown, and see Figure 1 In some embodiments, the photovoltaic power generation module 11 includes a plurality of thin-film photovoltaic cells 111, which have a stacked arrangement in a folded state and an unfolded state to form a plane.
[0041] This embodiment designs the photovoltaic power generation module 11 as a foldable structure, which significantly reduces the overall volume when folded, making it easy to carry and store. It is suitable for outdoor leisure, camping and other scenarios, and improves the foldability and practicality of the photovoltaic sunshade 100.
[0042] Figure 10 This is a schematic connection diagram of the bracket 14 and the umbrella holder 12 according to one embodiment of the present invention. Figure 10 As shown, in some embodiments, there are multiple supports 14, which are evenly arranged on opposite sides of the umbrella support 12. Two adjacent supports 14 located on the same side of the umbrella support 12 are rotatably connected, and one of the supports 14 is rotatably connected to the umbrella support 12. Each thin-film photovoltaic cell 111 is covered on one support 14.
[0043] This embodiment uses thin-film photovoltaic cells 111, which can reduce the weight of the photovoltaic sunshade 100, making it easy to carry and store, and also generates high power.
[0044] In some embodiments, two thin-film photovoltaic cells 111 located on the same side of the umbrella support 12 are in an unfolded state along a second direction, and all thin-film photovoltaic cells 111 form a square when in the unfolded state. In other embodiments, the multiple thin-film photovoltaic cells 111 may also form other shapes when in the unfolded state, such as circles, polygons, etc.
[0045] In some embodiments, two adjacent supports 14 located on the same side of the umbrella support 12 are hinged together by a hinge 113. The support 14 located on the same side of the umbrella support 12 closest to the support rod 40 is hinged to the umbrella support 12 by a hinge 113.
[0046] In some embodiments, all thin-film photovoltaic cells 111 located on the same side of the umbrella holder 12 are folded up, and then the thin-film photovoltaic cells 111 on both sides of the umbrella holder 12 are folded up, thereby putting all thin-film photovoltaic cells 111 in a folded state. See [link to documentation]. Figure 9 .
[0047] In some embodiments, the number of thin-film photovoltaic cells 111 is four. Two thin-film photovoltaic cells 111 located on the same side of the umbrella holder 12 are defined as the first thin-film photovoltaic cell and the second thin-film photovoltaic cell, respectively. Two thin-film photovoltaic cells 111 located on the other side of the umbrella holder 12 are defined as the third thin-film photovoltaic cell and the fourth thin-film photovoltaic cell, respectively.
[0048] Specifically, fold and store the umbrella according to the following steps: Step 1: Fold the support 14 corresponding to the second thin-film photovoltaic cell downward by 180° with the hinge 113 as the axis to overlap with the first thin-film photovoltaic cell. Similarly, fold the support 14 corresponding to the fourth thin-film photovoltaic cell downward by 180° with the hinge 113 as the axis to overlap with the third thin-film photovoltaic cell.
[0049] Step 2: While pulling out the positioning pin 32, pull down the handle 36 to move the slider 31 down along the slide groove 41, so as to rotate the umbrella support 12 until the photovoltaic power generation module 11 is perpendicular to the ground. Then insert the positioning pin 32 into the bottom limit groove 42.
[0050] Step 3: Simultaneously flip the folded first and second thin-film photovoltaic cells inward by 90°, and simultaneously flip the folded third and fourth thin-film photovoltaic cells inward by 90° to complete the umbrella folding operation. The umbrella opening process is the reverse.
[0051] Figure 11 This is a schematic structural diagram of a thin-film photovoltaic cell 111 according to an embodiment of the present invention. Figure 11 As shown, in some embodiments, each thin-film photovoltaic cell 111 has a positive electrode tab 115 and a negative electrode tab 114. Here, the positive electrode tab 115 and the negative electrode tab 114 are mounted on the same side of the thin-film photovoltaic cell 111.
[0052] Figure 12 This is a schematic connection diagram of the positive electrode tab 115 and negative electrode tab 114 of a plurality of thin-film photovoltaic cells 111 according to an embodiment of the present invention. Figure 12 As shown, and see Figure 6 The connecting rod 20 has a first wire-passing hole arranged along its extension direction, the support rod 40 has a second wire-passing hole 43 arranged along its extension direction, and the umbrella holder 12 has a third wire-passing hole arranged along its extension direction. The positive electrode tabs 115 of multiple thin-film photovoltaic cells 111 are electrically connected via a positive electrode bus 116, and the negative electrode tabs 114 of multiple thin-film photovoltaic cells 111 are electrically connected via a negative electrode bus 117. Both the positive electrode bus 116 and the negative electrode bus 117 pass through the first wire-passing hole, the second wire-passing hole 43, and the third wire-passing hole. Here, the positive electrode tabs 115 of each thin-film photovoltaic cell 111 are interconnected by the positive electrode bus 116, and the negative electrode tabs 114 of each thin-film photovoltaic cell 111 are interconnected via the negative electrode bus 117. The positive busbar 116 and the negative busbar 117 converge at the end of the umbrella holder 12 and are led out through the third wire passage hole inside the umbrella holder 12. Then, they are introduced into the second wire passage hole 43 inside the support rod 40 through the first wire passage hole of the connecting rod 20. Here, the counterweight base 50 is provided with a wiring interface, and both the positive busbar 116 and the negative busbar 117 are connected to the wiring interface.
[0053] This embodiment avoids power line leakage by introducing the positive busbar 116 and negative busbar 117 into the umbrella holder 12, connecting rod 20 and support rod 40, thereby improving electrical safety and enhancing the aesthetics of the photovoltaic sunshade umbrella 100.
[0054] In some embodiments, this invention also provides an energy storage system, which includes the aforementioned photovoltaic sunshade 100, a micro-inverter, and / or an energy storage power supply. Each thin-film photovoltaic cell 111 is provided with a positive electrode tab 115 and a negative electrode tab 114. The micro-inverter is connected to the positive electrode tab 115 via a positive bus 116 and to the negative electrode tab 114 via a negative bus 117. The micro-inverter is used to convert the direct current (DC) power from the thin-film photovoltaic cell 111 into alternating current (AC). The energy storage power supply is connected to the positive electrode tab 115 via a positive bus 116 and to the negative electrode tab 114 via a negative bus 117. The energy storage power supply is used to store the DC power converted from solar energy by the thin-film photovoltaic cell 111. Details regarding the photovoltaic sunshade 100 are omitted here.
