[0039] Embodiment 1:

[0040] like Figure 1 to Figure 2 As shown, this embodiment provides a sunshade 100, which includes a support frame 2 and a plurality of photovoltaic modules 1. The plurality of photovoltaic modules 1 can be spliced ​​into a tarpaulin, and the support frame 2 is used to support the tarpaulin to use the tarpaulin to block sunlight. The photovoltaic module 1 includes a flexible photovoltaic panel 11 and a zipper 12. The zipper 12 includes a chain belt 121 and a pull head 122. The chain belt 121 is connected to the edge of the flexible photovoltaic panel 11. The pull head 122 can connect the chain belts 121 on two adjacent flexible photovoltaic panels 11, so that the adjacent flexible photovoltaic panels 11 are spliced ​​into one body, thereby being used as a tarpaulin.

[0041] Exemplarily, the flexible photovoltaic panels 11 can be arranged on the top surface of the support frame 2 after being spliced, and used as the roof of the awning 100 to better utilize solar light for power generation and to block sunlight.

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

[0043] To ensure the fixing effect of the chain belt 121 and the edge of the flexible photovoltaic panel 11, the chain belt 121 and the edge of the flexible photovoltaic panel 11 are fixed by sewing. The sewing thread passes through the edge of the chain belt 121 and the flexible photovoltaic panel 11 and fixes the two, and the fixing effect is firm and can meet the needs of outdoor use.

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

[0045] It is understandable that the flexible photovoltaic panel 11 and the chain belt 121 are fixed by sewing technology, and there is a certain gap between the flexible photovoltaic panel 11 and the chain belt 121. There is a possibility of water seepage in the gap, resulting in reduced waterproof performance of the tarpaulin, affecting the use effect and life of the awning 100.

[0046] To solve the above problems, 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. A waterproof elastic layer 13 is sandwiched between the chain belt 121 and the flexible photovoltaic panel 11. The waterproof elastic layer 13 is elastically deformed by the chain belt 121 and the flexible photovoltaic panel 11, so as to better fill the gap between the chain belt 121 and the flexible photovoltaic panel 11, thereby reducing the possibility of water seepage between the chain belt 121 and the flexible photovoltaic panel 11 as much as possible, thereby improving the waterproof effect and service life of the awning 100 and improving the user experience.

[0047] In addition, after the flexible photovoltaic panel 11 and the chain belt 121 are connected by the sewing process, the sewing thread will pass through the flexible photovoltaic panel 11 and the chain belt 121, thereby forming a seam hole that allows the sewing thread to pass through the flexible photovoltaic panel 11 and the chain belt 121, which poses a risk of water seepage. 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 seam hole on the waterproof elastic layer 13. Since the waterproof elastic layer 13 has a certain elasticity, it can shrink the seam hole on itself 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, so as to reduce the possibility of water seepage at the seam, thereby improving the waterproof effect of the awning 100 and improving the user experience.

[0048] Specifically, the substrate 112 in the flexible photovoltaic panel 11 is connected to the link belt 121 by a sewing process to avoid damaging the battery 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 on the basis of sealing the gap between the flexible photovoltaic panel 11 and the chain belt 121, so as to prevent rainwater from penetrating into the inner side of the tarpaulin.

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

[0051] Optionally, the zipper 12 may be a waterproof zipper to prevent the zipper 12 from being soaked by rainwater and seeping into the inner side of the tarpaulin.

[0052] In order to improve the fixing effect between the chain belt 121 and the flexible photovoltaic panel 11, as Figure 3 As shown, a clamping groove 1121 is provided on the end surface of the flexible photovoltaic panel 11 along the thickness direction, and the clamping groove 1121 is a through groove that penetrates at both ends, and the chain belt 121 extends into the clamping groove 1121, and the waterproof elastic layer 13 is stacked with the chain belt 121 and is located in the clamping groove 1121. When two adjacent flexible photovoltaic panels 11 are connected by a zipper 12, the chain belt 121 and the slider 122 are located between the two flexible photovoltaic panels 11. By providing the clamping groove 1121, the chain belt 121 can be positioned, and the positioning accuracy of the chain belt 121 and the flexible photovoltaic panel 11 is improved, which is conducive 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 sealing structure. Even if rainwater penetrates into the clamping groove 1121, it cannot directly flow to the inner side of the flexible photovoltaic panel 11, which is conducive to improving the waterproof effect of the awning 100.

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

[0054] In some other embodiments, the waterproof elastic layer 13 can be roughly U-shaped, and the waterproof elastic layer 13 is sleeved outside the edge of one side 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 utilized to fill the assembly gap in the clamping groove 1121 to improve the sealing effect.

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

[0056] For example, when the flexible photovoltaic panel 11 is rectangular in shape, the length direction of the flexible photovoltaic panel 11 is defined as the Y direction, and the width direction is defined as the X direction. The chain belts 121 can be set at both ends of the width direction of the flexible photovoltaic panel 11, and a pull head 122 is set on one of the chain belts 121. When several flexible photovoltaic panels 11 are spliced, the chain belts 121 without pull heads 122 and the 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 achieve splicing. In this arrangement, the structure of each flexible photovoltaic panel 11 is the same, and there is no need to distinguish the specific position during splicing, which is convenient for operation.

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

[0058] In some embodiments, in combination Figure 1 and Figure 4 As shown, a folding seam 111 can also be provided on the flexible photovoltaic panel 11, 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, thereby improving the storage effect of the flexible photovoltaic panel 11; on the other hand, the 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 top angle of a specific angle when in use, so as to adjust the illumination angle of the battery cell 113, which can not only make better use of sunlight, but also divert rainwater on the battery cell 113, thereby reducing the residence time of rainwater on the flexible photovoltaic panel 11, so as to avoid water seepage of the flexible photovoltaic panel 11.

[0059] Exemplarily, the folding seam 111 may be arranged to extend along the width direction of the flexible photovoltaic panel 11 , and one or more folding seams 111 may 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 the top surface of the substrate 112 has two placement areas spaced apart along the length direction, each placement area is installed with a battery cell 113, and a folding seam 111 is formed between the two placement areas to utilize the flexibility of the substrate 112 itself to achieve bending of the flexible photovoltaic panel 11 along the folding seam 111.

[0061] Exemplarily, the substrate 112 can be made of materials such as polyvinylidene fluoride (PVC), polyolefin thermoplastic elastomer (TPO), polyvinylidene fluoride (PCVDF), etc., or the substrate 112 can be made of waterproof cloth, as long as it can support the battery cell 113 and can be bent itself.

[0062] In some other embodiments, the substrate 112 is provided with a reduced thickness area between two placement areas to form a folding seam 111 , and the thickness of the reduced thickness area is smaller than the thickness of the placement area, so that the formed folding seam 111 is easier to deform and can be bent more smoothly.

[0063] In some embodiments, a connector 16 is provided on the flexible photovoltaic panel 11, so that the flexible photovoltaic panel 11 can be connected to an external device through the connector 16. For example, the connector 16 can be provided on the lower end surface of the flexible photovoltaic panel 11, and the connector 16 can be, but is not limited to, a Velcro, a loop or a connecting rope. When a Velcro or a loop is used, it can be put on the support frame 2; when a connecting rope is used, it can be tied to the support frame 2.

[0064] like Figure 5 and Figure 6 As shown, in the current embodiment, the support frame 2 is a detachable support frame, and the support frame 2 is spliced ​​by a beam 21 and a column 22. According to different needs, the support frame 2 can be set to different forms such as a flat roof or a ridge, and the flexible photovoltaic panel 11 is fixed on the beam 21 by a connector 16, so as to facilitate storage. It can be understood that the specific number of beams 21 and columns 22 can be determined according to the specific number of splicing of the flexible photovoltaic panel 11. In the current embodiment, the beams 21 and the beams 21, and the columns 22 and the beams 21 can be connected by a connector 23, and the connector 23 includes at least two connection ports, so that a two-way connection joint, a three-way connection joint or a four-way connection joint can be flexibly formed, which is convenient for matching various forms of connection. The connector 23 can adopt the connector 23 in the prior art, and the column 22 and the beam 21 can adopt a retractable straight tube with an elastic pin in the prior art, and the connector 23 can be matched with a pin hole, and the specific details are not repeated. In the current embodiment, a pull rope connection hole is also provided on the connecting head 23 for connecting the pull rope 3 .

[0065] In the current embodiment, the column 22 is arranged at one end away from the cross beam 21, and has a detachable connector 24, so that the column 22 can be plugged into the ground through the connector 24, which facilitates the support and stability of the awning 100. The connector 24 can be a ground fork in the prior art.

[0066] In some embodiments, in combination Figure 1 , Figure 4 and Figure 7As shown, the support frame 2 includes two beams 21 spliced ​​along the length direction of the flexible photovoltaic panel 11, and the two beams 21 are connected by a connector 23 and are set at an angle a, 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 located at the folding seam 111 are respectively made by the beams 21 at corresponding positions, so that the flexible photovoltaic panel 11 is ridge-shaped, and the flexible photovoltaic panel 11 forms a tip at the folding seam 111. Rainwater dripping on the flexible photovoltaic panel 11 can flow along the top surface of the flexible photovoltaic panel 11, and then drip on the two end edges of the flexible photovoltaic panel 11 in the length direction, and will not stay on the flexible photovoltaic panel 11 for a long time. On the one hand, it can avoid water seepage in the flexible photovoltaic panel 11, and on the other hand, it is beneficial for the flexible photovoltaic panel 11 to fully receive and utilize sunlight.

[0067] Embodiment 2:

[0068] This embodiment provides a sunshade awning 100 , which is different from the 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 link 121 is stacked with the edge of the flexible photovoltaic panel 11, that is, the link 121 can be stacked on the top surface of the substrate 112 or on the bottom surface of the substrate 112, and part of the link 121 overlaps with the edge of the flexible photovoltaic panel 11, and the overlapping area is fixedly connected by sewing. This fixing method does not require the clamping groove 1121 to be set on the substrate 112, which is conducive to ensuring the strength of the substrate 112 to meet the support effect of the battery cell 113.

[0070] In order 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 rain, 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 to the center of the flexible photovoltaic panel 11, and two adjacent chain belts 121 are bent toward each other and connected by a pull head 122. This arrangement can reduce the gap between two adjacent flexible photovoltaic panels 11. On the one hand, reducing the gap can reduce the probability of water seeping inward through the gap to improve the waterproof effect; on the other hand, it can make the structure of the flexible photovoltaic panels 11 more compact after splicing, and on the basis of the overall size of the photovoltaic module 1 remaining unchanged, increase the effective illumination area of ​​the battery cell 113 to increase the power supply.

[0072] In addition, two adjacent chain belts 121 are bent toward each other and then connected by a pull head 122. When the chain belt 121 is located above the flexible photovoltaic panel 11, the two connected chain belts 121 can block the splicing gap between the two adjacent flexible photovoltaic panels 11 from above, thereby reducing the flow of rainwater into the splicing gap; when the chain belt 121 is located below the flexible photovoltaic panel 11, the two connected chain belts 121 can form a circulation channel 14. Even if a small amount of water droplets penetrate into the splicing gap between the two adjacent flexible photovoltaic panels 11, they can be diverted to the outer sides of the two ends of the flexible photovoltaic panel 11 in the length direction as much as possible through the formed circulation channel 14, so as to improve the overall waterproof performance of the awning 100.

[0073] In order to further improve the waterproof performance of the awning 100, in some embodiments, a waterproof layer 15 can also be provided on the photovoltaic assembly 1, and the waterproof layer 15 is coated on the edge end of the flexible photovoltaic panel 11 so as to cover the connection area where the chain belt 121 and the flexible photovoltaic panel 11 overlap to prevent water from penetrating and improve the waterproof performance.

[0074] Specifically, the waterproof layer 15 covers the top surface, side surfaces and bottom surface 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 then the chain belt 121 and the waterproof elastic layer 13 are placed, and then the waterproof layer 15 is fixed by sewing. In other words, the sewing line will pass through the waterproof layer 15 to fix the chain belt 121 and the flexible photovoltaic panel 11 while fixing the waterproof layer 15 and the waterproof elastic layer 13, thereby improving the reliability of the photovoltaic module 1.

[0076] In some other embodiments, the waterproof layer 15 can be coated after the sewing process, that is, the sewing thread will not pass through the waterproof layer 15 to avoid thread holes on the waterproof layer 15 that affect the waterproof effect. Optionally, the waterproof layer 15 can be fixed by bonding after sewing.

[0077] Optionally, the waterproof layer 15 may be a waterproof cloth or a waterproof membrane layer.

[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 , so that the waterproof performance is improved by the waterproof layer 15 and the waterproof elastic layer 13 .

[0079] Specifically, Figure 8As shown, the waterproof elastic layer 13 is provided with three layers, namely a first waterproof elastic layer, a second waterproof elastic layer and a third waterproof elastic layer. The first waterproof elastic layer is arranged between the waterproof layer 15 and the top surface of the flexible photovoltaic panel 11, the second waterproof elastic layer is arranged between the bottom surface of the flexible photovoltaic panel 11 and the chain belt 121, and the third waterproof elastic layer is arranged between the waterproof layer 15 located in the circulation channel 14 and the chain belt 121. By arranging the above three layers of waterproof elastic layers 13, triple sealing can be achieved to improve the waterproof performance.

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

[0081] Embodiment three:

[0082] This embodiment provides a sunshade 100, which is different from the first or second embodiment in that the flexible photovoltaic panel 11, the zipper 12 and the waterproof elastic layer 13 can be connected by heat pressing, instead of the sewing connection method in the first or second embodiment, so as to avoid the generation of sewing holes. The waterproof elastic layer 13, the zipper 12 and the flexible photovoltaic panel 11 can be tightly connected together by heat pressing, so as to further improve the waterproof performance.

[0083] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
