The embodiments described below by referring to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0043] The embodiment provides a BIPV laminated frame which can be arranged outside a photovoltaic module when the photovoltaic module is laminated, so as to prevent the edge glass of the photovoltaic module from being excessively bent to affect vacuum extraction in the laminating process and cause large-area bubble problems at the edge.
[0044] As shown in Figure 1 , the BIPV laminated frame comprises a plurality of connecting plates 1, the plurality of connecting plates 1 are sequentially connected end to end, and are spliced to form a frame space, and the photovoltaic module 100 is placed in the frame space. In the embodiment, the BIPV laminated frame comprises four connecting plates 1, the four connecting plates 1 are sequentially connected end to end to form a rectangular BIPV laminated frame. Of course, in other embodiments, the connecting plates 1 can be five, six or other numbers, and the specific number of the connecting plates 1 can be designed according to the shape of the BIPV laminated frame, and the shape of the BIPV laminated frame needs to be adapted to the shape of the photovoltaic module 100.
[0045] Continuing to refer to Figures 1-3 , the end face of one end of the connecting plate 1 is convexly provided with a connecting portion 11 in the length direction, and the side face of the connecting plate 1 facing the frame space is provided with a connecting groove 12 in the length direction, the connecting portion 11 of one connecting plate 1 can be inserted into the connecting groove 12 of another connecting plate 1 adjacent thereto, so as to realize reliable connection between the plurality of connecting plates 1. Further, the connecting portion 11 can slide along the connecting groove 12. That is, the connection position of the connecting portion 11 of one connecting plate 1 in the length direction of another connecting plate 1 adjacent thereto is adjustable. When the connecting portion 11 of one connecting plate 1 slides, the remaining connecting plates 1 can be correspondingly slid, so as to realize free adjustment of the size of the BIPV laminated frame, and further meet the use requirements of photovoltaic modules 100 of different specifications, and effectively reduce the production cost.
[0046] Specifically, as shown in Figure 3 and Figure 4 , the connecting portion 11 comprises a connecting block 111 and a limiting block 112 connected to each other, the connecting block 111 is connected between the limiting block 112 and the end face of the connecting plate 1, and the thickness of the connecting block 111 is less than the thickness of the limiting block 112. The side wall of the slot of the connecting groove 12 is convexly provided with a limiting protrusion 121, the distance between the limiting protrusion 121 and the opposite position of the other side wall of the connecting groove 12 is less than the thickness of the limiting block 112 and is not less than the thickness of the connecting block 111. The connecting portion 11 of one connecting plate 1 can be slidably inserted into the connecting groove 12 of another connecting plate 1, so as to reliably connect the two connecting plates 1.
[0047] In the embodiment, referring to Figure 4The connecting block 111 and the limiting block 112 are coaxially arranged, and the connecting part 11 has a T-shaped structure. The side walls on both sides of the slot of the connecting slot 12 are symmetrically provided with limiting protrusions 121, the distance between the two limiting protrusions 121 is less than the thickness of the limiting block 112, and is not less than the thickness of the connecting block 111. When the adjacent two connecting plates 1 slide relative to each other, the two limiting protrusions 121 can play a blocking role, so as to prevent the connecting part 11 of one connecting plate 1 from being pulled out of the connecting slot 12 of the other connecting plate 1.
[0048] Of course, in other embodiments, the connecting block 111 and the limiting block 112 are flush on one side, the connecting part 11 has an L-shaped structure, one side wall of the slot of the connecting slot 12 is provided with a limiting protrusion 121, and the limiting protrusion 121 corresponds to the recess of the L-shaped connecting part 11. In this way, the connecting part 11 of one connecting plate 1 can be inserted into the connecting slot 12 of the other connecting plate 1, and the connecting part 11 will not be pulled out when sliding in the connecting slot 12.
[0049] As shown in Figure 2 and Figure 5 , the BIPV laminated frame further comprises a fixing member 2. The fixing member 2 is arranged at one end of the connecting plate 1 protruding with the connecting part 11, and is located on the side of the connecting plate 1 away from the connecting slot 12. When the connecting part 11 of one connecting plate 1 is inserted into the connecting slot 12 of the other connecting plate 1 adjacent thereto, the fixing member 2 on the connecting plate 1 can be connected with the other connecting plate 1. That is, after a plurality of connecting plates 1 are connected in sequence and the size of the BIPV laminated frame is adjusted, the fixing member 2 can fix the position between the adjacent two connecting plates 1, so as to prevent the relative sliding between the adjacent two connecting plates 1 in the subsequent use process, causing the size of the BIPV laminated frame to change, thereby affecting the product qualification rate of the photovoltaic module 100 after lamination.
[0050] Specifically, referring to Figure 5 , the fixing member 2 has an L-shaped structure, including a first fixing part 21 and a second fixing part 22 arranged perpendicularly. The first fixing part 21 abuts against the side surface of the connecting plate 1, and the second fixing part 22 extends away from the connecting plate 1, and the second fixing part 22 is flush with the end surface of the connecting plate 1. The second fixing part 22 on one connecting plate 1 can be fixedly connected with the other connecting plate 1.
[0051] Further, a connecting hole 221 is formed in the second fixing part 22, and a fastener can be threaded through the connecting hole 221 on one connecting plate 1 and screwed with the other connecting plate 1. The fastener can be selected as a threaded fastener such as a screw or a bolt, so as to facilitate disassembly.
[0052] Optionally, as shown in Figure 7As shown, the bottom of the BIPV laminated frame is selectively provided with a gasket 4, and the shape of the gasket 4 matches the shape of the connecting plate 1. By adding the gasket 4, the thickness of the BIPV laminated frame can be adjusted. Specifically, the thickness of the gasket 4 can be selected as 2mm, 5mm, etc., which can be set according to actual needs, and is not limited here.
[0053] Optionally, as shown, Figure 6 As shown, a plurality of BIPV laminated frames are arranged in a stacked manner, and a positioning structure is arranged between the BIPV laminated frame in the upper layer and the BIPV laminated frame in the lower layer. The positioning mechanism is used to prevent the misalignment of the plurality of BIPV laminated frames arranged in a stacked manner, and to ensure the stability of the plurality of BIPV laminated frames arranged in a stacked manner.
[0054] Specifically, the positioning structure includes a positioning protrusion 31 and a positioning groove 32 matched with the positioning protrusion 31. One of the positioning protrusion 31 and the positioning groove 32 is arranged on the top surface of the connecting plate 1, and the other is arranged on the bottom surface of the connecting plate 1, and the positioning protrusion 31 is opposite to the positioning groove 32. When two BIPV laminated frames are stacked, the positioning protrusion 31 of one of the BIPV laminated frames is inserted into the positioning groove 32 of the other BIPV laminated frame, so that the two BIPV laminated frames are arranged in a stacked manner. At the same time, due to the cooperation of the positioning protrusion 31 and the positioning groove 32, even if the plurality of BIPV laminated frames arranged in a stacked manner are shaken, the two adjacent BIPV laminated frames will not be separated, and the structure is stable.
[0055] In this embodiment, the positioning protrusion 31 and the positioning groove 32 are both wave structures symmetrically arranged on the upper and lower end surfaces of the connecting plate 1 along the length direction of the connecting plate 1. In another embodiment, the positioning protrusion 31 and the positioning groove 32 can also be rectangular protrusions and rectangular grooves symmetrically arranged on the upper and lower end surfaces of the connecting plate 1 along the length direction of the connecting plate 1. In another embodiment, a plurality of positioning protrusions 31 and a plurality of positioning grooves 32 are arranged on the connecting plate 1, and the positioning protrusion 31 and / or the positioning groove 32 on the upper end surface of the connecting plate 1 is opposite to the positioning groove 32 and / or the positioning protrusion 31 on the lower end surface of the connecting plate 1.
[0056] Further, the height of the positioning protrusion 31 is less than the depth of the positioning groove 32, so as to prevent the deformation of the positioning protrusion 31 and the positioning groove 32 due to thermal expansion and contraction after multiple laminations, and to prevent the abnormal increase of the thickness of the positioning protrusion 31, which affects the reliable connection of the positioning protrusion 31 and the positioning groove 32.
[0057] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and also impossible to exhaust all the implementation modes. Any modification, equivalent replacement and improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application claims.
