[0039] Example 1:

[0040] like Figures 1 to 2 As shown, this embodiment provides a sunshade 100, which includes a support frame 2 and several photovoltaic modules 1. The photovoltaic modules 1 can be spliced ​​together to form a canopy. The support frame 2 is used to support the canopy to block sunlight. The photovoltaic module 1 includes a flexible photovoltaic panel 11 and a zipper 12. The zipper 12 includes a chain 121 and a zipper pull 122. The chain 121 is connected to the edge of the flexible photovoltaic panel 11, and the zipper pull 122 can connect the chain 121 on two adjacent flexible photovoltaic panels 11, so that the adjacent flexible photovoltaic panels 11 can be spliced ​​together as a whole, thereby serving as a canopy.

[0041] For example, the flexible photovoltaic panels 11 can be spliced ​​together and placed on the top surface of the support frame 2 to serve as the roof of the sunshade 100, so as to better utilize sunlight for power generation and block sunlight.

[0042] In some other embodiments, the tarpaulin formed by splicing the flexible photovoltaic panels 11 can not only be located on top of the support frame 2, but also cover at least one side of the support frame 2 to better provide a shading effect.

[0043] To ensure the secure fastening of the chain belt 121 to the edge of the flexible photovoltaic panel 11, the edges of the chain belt 121 and the flexible photovoltaic panel 11 are fixed by sewing. The sewing thread passes through the edges of the chain belt 121 and the flexible photovoltaic panel 11, securing them together firmly and meeting the requirements for outdoor use.

[0044] like Figure 2As shown, the flexible photovoltaic panel 11 includes a substrate 112 and a plurality of solar cells 113 disposed on the top surface of the substrate 112. The plurality of solar cells 113 are connected in series and parallel to form an assembly for receiving sunlight and converting it into electrical energy.

[0045] It is understandable that when the flexible photovoltaic panel 11 and the chain belt 121 are fixed by sewing, there is a certain gap between the flexible photovoltaic panel 11 and the chain belt 121. This gap may allow water to seep in, which will reduce the waterproof performance of the tarpaulin and affect the use effect and lifespan of the sunshade 100.

[0046] To solve the above problems, such as Figure 3 As shown, in this embodiment, a waterproof elastic layer 13 is sandwiched between the chain belt 121 and the flexible photovoltaic panel 11. The waterproof elastic layer 13 sandwiched between the chain belt 121 and the flexible photovoltaic panel 11 undergoes elastic deformation under the action of the chain belt 121 and the flexible photovoltaic panel 11, better filling the gap between them. This minimizes the possibility of water seepage through the chain belt 121 and the flexible photovoltaic panel 11, thereby improving the waterproof effect and service life of the sunshade 100 and enhancing the user experience.

[0047] Furthermore, after the flexible photovoltaic panel 11 and the chain belt 121 are connected by a sewing process, the sewing thread will pass through the flexible photovoltaic panel 11 and the chain belt 121, thus forming a gap in the flexible photovoltaic panel 11 and the chain belt 121 that allows the sewing thread to pass through, posing a risk of water leakage. In this embodiment, by sandwiching a waterproof elastic layer 13 between the chain belt 121 and the flexible photovoltaic panel 11, the sewing thread will form a gap in the waterproof elastic layer 13. Since the waterproof elastic layer 13 has a certain degree of elasticity, it can shrink its own gap after being sewn to better wrap the sewing thread, reduce or even eliminate the gap between the waterproof elastic layer 13 and the sewing thread, thereby reducing the possibility of water leakage at the seam, improving the waterproof effect of the sunshade 100, and improving the user experience.

[0048] Specifically, the substrate 112 in the flexible photovoltaic panel 11 is connected to the chain belt 121 by a sewing process to avoid damaging the solar cell 113.

[0049] Optionally, the waterproof elastic layer 13 may be made of a waterproof elastic material to prevent rainwater from wetting the waterproof elastic layer 13 itself while sealing the gap between the flexible photovoltaic panel 11 and the chain belt 121, so as to prevent rainwater from penetrating into the inside of the tarpaulin.

[0050] For example, the waterproof elastic layer 13 can be an elastic adhesive layer, such as a foamed adhesive layer, a flexible adhesive layer, or a double-sided adhesive layer. By using an elastic adhesive layer as the waterproof elastic layer 13, not only can the waterproof sealing effect be achieved, but the flexible photovoltaic panel 11 and the zipper 12 can also be bonded and fixed, further improving the fixing effect of the flexible photovoltaic panel 11 and the zipper 12.

[0051] Alternatively, the zipper 12 can be a waterproof zipper to prevent water from seeping into the inside of the tarpaulin when the zipper 12 gets wet from rain.

[0052] To improve the fixing effect between the chain belt 121 and the flexible photovoltaic panel 11, such as Figure 3 As shown, a clamping groove 1121 is provided on the end face of the flexible photovoltaic panel 11 along the thickness direction. The clamping groove 1121 is a through groove with both ends extending through it. The chain belt 121 extends into the clamping groove 1121. The waterproof elastic layer 13 is stacked with the chain belt 121 and located within the clamping groove 1121. When two adjacent flexible photovoltaic panels 11 are connected by a zipper 12, the chain belt 121 and the zipper head 122 are located between the two flexible photovoltaic panels 11. By providing the clamping groove 1121, the chain belt 121 can be positioned, improving the positioning accuracy of the chain belt 121 and the flexible photovoltaic panel 11, which is beneficial to improving the fixing effect of the chain belt 121 and the flexible photovoltaic panel 11. In addition, the chain belt 121 extends into the clamping groove 1121, and the chain belt 121 and the clamping groove 1121 can form a labyrinth seal structure. Even if rainwater seeps into the clamping groove 1121, it cannot flow directly to the inside of the flexible photovoltaic panel 11, which is beneficial to improving the waterproof effect of the sunshade 100.

[0053] In some embodiments, waterproof elastic layers 13 are stacked on both sides of the chain 121 to fully seal the gap between the opposite sides of the chain 121 and the inner wall of the clamping groove 1121, thereby improving the waterproof effect.

[0054] In some other embodiments, the waterproof elastic layer 13 may be generally U-shaped and is fitted over one edge of the chain belt 121 to wrap the chain belt 121 from three sides. When the chain belt 121 and the waterproof elastic layer 13 are fixed in the clamping groove 1121, the elastic properties of the waterproof elastic layer 13 can be used to fill the assembly gap in the clamping groove 1121 to improve the sealing effect.

[0055] Combination Figures 1-3 As shown, in order to improve the convenience of connection, in some embodiments, chain belts 121 are provided at both ends of the flexible photovoltaic panel 11, and a pull head 122 is provided on at least one end of the chain belt 121, so that the flexible photovoltaic panel 11 can be spliced ​​in one direction.

[0056] For example, when the flexible photovoltaic panel 11 is rectangular, the length direction of the flexible photovoltaic panel 11 is defined as the Y direction, and the width direction as the X direction. Chain belts 121 can be disposed at both ends of the width direction of the flexible photovoltaic panel 11, with one chain belt 121 having a pull head 122. When several flexible photovoltaic panels 11 are spliced ​​together, chain belts 121 without pull heads 122 and chain belts 121 with pull heads 122 are alternately arranged, so that the connection position of two adjacent flexible photovoltaic panels 11 can be connected by one pull head 122 to connect two chain belts 121, thus achieving splicing. With this arrangement, each flexible photovoltaic panel 11 has the same structure, eliminating the need to distinguish the specific position during splicing, thus facilitating operation.

[0057] In other embodiments, the specific size and shape of the flexible photovoltaic panel 11 are not specifically limited, and can be flexibly set according to different needs.

[0058] In some embodiments, combined with Figure 1 and Figure 4 As shown, the flexible photovoltaic panel 11 can also be provided with a folding seam 111, so that the flexible photovoltaic panel 11 can be bent along the folding seam 111. On the one hand, the flexible photovoltaic panel 11 can be folded and stored, improving the storage effect of the flexible photovoltaic panel 11. On the other hand, the included angle between the parts of the flexible photovoltaic panel 11 located on both sides of the folding seam 111 can be adjusted as needed, so that the flexible photovoltaic panel 11 has a specific apex angle when in use, so as to adjust the illumination angle of the solar cell 113. This not only makes better use of sunlight, but also guides the rainwater on the solar cell 113, reducing the time that rainwater stays on the flexible photovoltaic panel 11, thus preventing water seepage from the flexible photovoltaic panel 11.

[0059] For example, the fold seam 111 can be configured to extend along the width direction of the flexible photovoltaic panel 11, and one or more can be distributed along the length direction of the flexible photovoltaic panel 11.

[0060] In some embodiments, the substrate 112 is made of a flexible material, and two placement areas are arranged at intervals along the length direction on the top surface of the substrate 112. A solar cell 113 is installed in each placement area, and a folding seam 111 is formed between the two placement areas so that the flexible photovoltaic panel 11 can be bent along the folding seam 111 by utilizing the flexibility of the substrate 112 itself.

[0061] For example, the substrate 112 can be made of materials such as polyvinylidene fluoride (PVC), polyolefin thermoplastic elastomer (TPO), polyvinylidene fluoride (PCVDF), or the substrate 112 can be made of waterproof fabric, as long as it can support the battery cell 113 and be flexible.

[0062] In some other embodiments, the substrate 112 has a thickness reduction region between two placement areas to form a folding seam 111. The thickness of the thickness reduction region is less than the thickness of the placement areas, so that the formed folding seam 111 is more easily deformed and can be bent more smoothly.

[0063] In some embodiments, the flexible photovoltaic panel 11 is provided with a connector 16 to connect the flexible photovoltaic panel 11 to an external device. Exemplarily, the connector 16 may be located on the lower end face of the flexible photovoltaic panel 11, and the connector 16 may be, but is not limited to, Velcro, a loop, or a connecting rope. When Velcro or a loop is used, it can be fitted onto the support frame 2; when a connecting rope is used, it can be fastened to the support frame 2.

[0064] like Figure 5 and Figure 6 As shown, in this embodiment, the support frame 2 is a detachable support frame, which is assembled from crossbeams 21 and columns 22. Depending on different needs, the support frame 2 can be configured as a flat roof or ridge roof, etc. The flexible photovoltaic panel 11 is fixed to the crossbeam 21 via connectors 16, thus facilitating storage. It is understood that the specific number of crossbeams 21 and columns 22 can be determined based on the specific number of flexible photovoltaic panels 11 assembled. In this embodiment, crossbeams 21 and columns 22 can be connected to each other via connectors 23. Connectors 23 include at least two connection ports, allowing for flexible two-way, three-way, or four-way connections to accommodate various connection types. Connectors 23 can be existing connectors, and columns 22 and crossbeams 21 can be existing retractable straight tubes with elastic pins. Pin holes can be provided on the connectors 23; specific details are not elaborated further. In the current embodiment, the connector 23 is also provided with a pull rope connection hole for connecting the pull rope 3.

[0065] In the current embodiment, the end of the column 22 facing away from the crossbeam 21 is provided with a detachable connector 24, so that the column 22 can be inserted into the ground through the connector 24, which facilitates the stable support of the sunshade 100. The connector 24 can be a ground fork of the prior art.

[0066] In some embodiments, combined with Figure 1 , Figure 4 and Figure 7As shown, the support frame 2 includes two crossbeams 21 spliced ​​along the length of the flexible photovoltaic panel 11. The two crossbeams 21 are connected by a connector 23 and set at an included angle α, so that when the flexible photovoltaic panel 11 is placed on the support frame 2, the flexible photovoltaic panel 11 can be bent at the folding seam 111, so that the two parts of the flexible photovoltaic panel 11 at the folding seam 111 are respectively formed by the crossbeams 21 at corresponding positions, making the flexible photovoltaic panel 11 ridge-shaped. The flexible photovoltaic panel 11 forms a pointed tip at the folding seam 111, so that rainwater dripping on the flexible photovoltaic panel 11 can flow along the top surface of the flexible photovoltaic panel 11, and drip at both ends of the flexible photovoltaic panel 11 along its length, and will not stay on the flexible photovoltaic panel 11 for a long time. On the one hand, it can prevent water seepage from the flexible photovoltaic panel 11, and on the other hand, it can help the flexible photovoltaic panel 11 to fully receive and utilize sunlight.

[0067] Example 2:

[0068] This embodiment provides a sunshade 100, which differs from the previous embodiment in that the connection structure between the chain belt 121 and the flexible photovoltaic panel 11 is different.

[0069] like Figure 8 As shown, the conveyor belt 121 is stacked on the edge of the flexible photovoltaic panel 11. That is, the conveyor belt 121 can be stacked on the top surface or the bottom surface of the substrate 112. Part of the conveyor belt 121 overlaps with the edge of the flexible photovoltaic panel 11, and the overlapping area is fixedly connected by a sewing process. This fixing method eliminates the need for clamping grooves 1121 on the substrate 112, which helps ensure the strength of the substrate 112 to provide adequate support for the solar cells 113.

[0070] To prevent the zipper 12 from being damaged by external environmental factors, in some embodiments, the edge of the flexible photovoltaic panel 11 is located above the chain belt 121, so that after two adjacent flexible photovoltaic panels 11 are spliced ​​together, at least part of the zipper 12 is located below the flexible photovoltaic panel 11. This not only improves the overall aesthetics, but also reduces the direct impact of rainwater, wind and sand on the zipper 12, thereby extending the life of the zipper 12 and reducing the possibility of water seepage.

[0071] In some embodiments, the chain belt 121 extends from the edge of the flexible photovoltaic panel 11 towards its center, and adjacent chains belts 121 are bent towards each other and connected by a pull head 122. This arrangement can reduce the gap between adjacent flexible photovoltaic panels 11. On the one hand, reducing the gap reduces the probability of water seeping inward through the gap, thereby improving the waterproof effect. On the other hand, it allows for a more compact structure after the flexible photovoltaic panels 11 are spliced ​​together, increasing the effective light-emitting area of ​​the solar cells 113 while keeping the overall size of the photovoltaic module 1 unchanged, thus increasing the power supply.

[0072] Furthermore, after two adjacent chain straps 121 are bent towards each other, they are connected by a pull head 122. When the chain straps 121 are above the flexible photovoltaic panel 11, the two connected chain straps 121 can block the splicing gap between the two adjacent flexible photovoltaic panels 11 from above, reducing the flow of rainwater into the splicing gap. When the chain straps 121 are below the flexible photovoltaic panel 11, the two connected chain straps 121 can form a flow channel 14. Even if a small amount of water droplets seep in through the splicing gap between the two adjacent flexible photovoltaic panels 11, they can be guided as far as possible to the outer sides of both ends of the flexible photovoltaic panel 11 in the length direction through the formed flow channel 14, thereby improving the overall waterproof performance of the sunshade 100.

[0073] To further improve the waterproof performance of the sunshade 100, in some embodiments, a waterproof layer 15 can also be provided on the photovoltaic module 1. The waterproof layer 15 covers the edge end of the flexible photovoltaic panel 11 so as to cover the connection area where the chain belt 121 overlaps with the flexible photovoltaic panel 11, so as to prevent water from seeping in and improve the waterproof performance.

[0074] Specifically, the waterproof layer 15 covers the top, sides and bottom of the flexible photovoltaic panel 11 to improve the waterproof effect.

[0075] In some embodiments, the waterproof layer 15 can be first wrapped around the edge of the flexible photovoltaic panel 11, and the chain belt 121 and the waterproof elastic layer 13 can be placed before being fixed by sewing. That is, the sewing thread will pass through the waterproof layer 15 to fix the waterproof layer 15 and the waterproof elastic layer 13 at the same time as fixing the chain belt 121 and the flexible photovoltaic panel 11, thereby improving the reliability of the photovoltaic module 1.

[0076] In some other embodiments, the waterproof layer 15 can be applied after the sewing process, meaning the sewing thread will not pass through the waterproof layer 15 to avoid any holes in the waterproof layer 15 that could affect its waterproofing effect. Alternatively, the waterproof layer 15 can be fixed by adhesive after sewing.

[0077] Alternatively, the waterproof layer 15 can be a waterproof fabric or a waterproof membrane.

[0078] In some embodiments, a waterproof elastic layer 13 is provided between the waterproof layer 15 and the chain belt 121, and between the waterproof layer 15 and the flexible photovoltaic panel 11, thereby improving the waterproof performance through the waterproof layer 15 and the waterproof elastic layer 13.

[0079] Specifically, such as Figure 8As shown, the waterproof elastic layer 13 consists of three layers: a first waterproof elastic layer, a second waterproof elastic layer, and a third waterproof elastic layer. The first waterproof elastic layer is disposed between the waterproof layer 15 and the top surface of the flexible photovoltaic panel 11. The second waterproof elastic layer is disposed between the bottom surface of the flexible photovoltaic panel 11 and the chain belt 121. The third waterproof elastic layer is disposed between the waterproof layer 15 and the chain belt 121 located within the flow channel 14. By disposing of the above three waterproof elastic layers 13, triple sealing can be achieved to improve waterproof performance.

[0080] In some other embodiments, only the first and second waterproof elastic layers may be provided, or only the second and third waterproof elastic layers may be provided. The specific number of layers and their positions can be set according to actual needs.

[0081] Example 3:

[0082] This embodiment provides a sunshade 100, which differs from Embodiment 1 or Embodiment 2 in that the flexible photovoltaic panel 11, zipper 12, and waterproof elastic layer 13 can be connected by heat pressing, replacing the stitching connection method in Embodiment 1 or Embodiment 2, thereby avoiding the formation of stitching holes. Heat pressing can tightly connect the waterproof elastic layer 13, zipper 12, and flexible photovoltaic panel 11 together, thereby further improving waterproof performance.

[0083] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
