[0038] In combination Figures 1 to 3 As shown in the drawings, the embodiments of the present application propose a long frame 10, comprising:

[0039] The first frame segment 110 extends in the first direction and has a first end surface S11;

[0040] The second frame segment 120 extends in the first direction and has a second end surface S12; the first end surface S11 and the second end surface S12 abut; wherein the cross-sectional area of the second frame segment 120 is smaller than the cross-sectional area of the first frame segment 110; and

[0041] The first corner code 30 connects the first frame segment 110 and the second frame segment 120.

[0042] In the technical scheme of the embodiment of the present application, the long side frame 10 is not formed integrally but is divided into a first frame segment 110 and a second frame segment 120, the first frame segment 110 and the second frame segment 120 are connected through the first corner code 30, and the end faces of the first frame segment 110 and the second frame segment 120 abut to realize the splicing assembly of the long side frame 10; wherein the cross-sectional area of the second frame segment 120 is smaller than that of the second frame segment 120, which helps to save the sectional material of the long side frame 10 and save the material cost.

[0043] In some embodiments, as Figure 2 The cross-sectional view of the first frame segment 110 is shown, which has an A face 111, a B face 113 and a C face 112; in the embodiment, the C face of the first frame segment 110 can be provided with a pressing block or a bolt hole. In some embodiments, the first frame segment 110 can also be provided as an A-face-free structure, and the C face has a bolt hole.

[0044] As Figure 3 The cross-sectional view of the second frame segment 120 without A face is shown, which only has a B face and a C face. In this structure, the second frame segment 120 is provided as an A-face-free segment to reduce dust accumulation and improve the light energy utilization rate of the photovoltaic module. In some embodiments, the width of the C face of the second frame segment without A face can be set smaller than that of the C face of the first frame segment to save material cost and maximize the optimization of structural material.

[0045] In some embodiments, the second frame segment 120 can also be provided as a frame segment without C face, which can reduce the cross-sectional area of the long side frame 10 and reduce material cost.

[0046] In some embodiments, the second frame segment 120 can be provided as a structure only with B face, i.e. without A face and without C face.

[0047] As an optional implementation of the above embodiment, as Figure 3 It is shown that the second cavity C12 is further provided with a reinforcing structure 130. Since the second frame segment 120 is provided as A-face-free and / or C-face-free and is provided with a reduced cross-sectional area, the reinforcing structure 130 is provided in the second cavity C12 to make the second frame segment 120 bear enough force.

[0048] For example, in some embodiments, the second frame section 120 is arranged between two first frame sections 110; after the laminated glass is placed, based on the stress analysis of the beam model, the maximum bending moment or internal force also exists in the middle of the second frame section 120; therefore, the second cavity C12 is provided with a reinforcing structure 130 to make the force bearing capacity of the second frame section 120 sufficient. For example, in some embodiments, a reinforcing rib is embedded in the second cavity C12 of the middle section of the second frame section 120, the height and width of the cross section of the reinforcing rib is close to that of the inner wall of the third cavity, the cross section of the reinforcing rib can be solid or in a hollow shape, and the material can be aluminum alloy or other high-strength metal or non-metal material. After the reinforcing rib is placed in a specific position in the middle section of the long side, the inner side B surface of the second frame section 120 can be grooved to fix the reinforcing rib inside by interference fit.

[0049] In some embodiments, the two ends of the long side frame 10 are provided with the first frame section 110 with the A surface and the C surface with bolt holes and a reinforcing section, while the middle section is provided with the second frame section 120 without the A surface and possibly with a shortened C surface, and the middle section of the second frame section 120 can be insufficient in strength at the maximum bending moment in the middle of the span. The cavity of the middle section of the frame can be locally reinforced to target the weak points of the reinforcing structure, and the length of the reinforcing rib can be adjusted to optimize the economy of the overall structure. In some cases, since the long side frame is divided into three sections, the length of the middle section will not be too long, so the difficulty of placing the reinforcing rib in the middle section of the frame will be reduced.

[0050] As an optional implementation of the above embodiment, as shown in Figure 3 The second frame section 120 includes a body part 121; the body part 121 is connected with the first frame section 110; the body part 121 has a supporting surface 1211, the supporting surface 1211 is provided with a protrusion 1212, the protrusion 1212 is used to abut against the bottom surface of the laminated glass; and,

[0051] a limiting part 122, the limiting part 122 is arranged on the supporting surface 1211 and extends away from the body part 121 in the height direction; the body part 121 and the limiting part 122 form a mounting area for mounting the laminated glass; the limiting part 122 has a limiting end 1221, the limiting end 1221 is arranged away from the body part 121, and the inner side of the limiting end 1221 has an inner inclined surface 1221a, the inner inclined surface 1221a is arranged towards the mounting area and forms an acute angle with the supporting surface 1211, and the inner inclined surface 1221a is used to abut against the top surface transition angle of the laminated glass.

[0052] In the technical scheme of the embodiment of the present application, the limiting portion 122 is arranged on the supporting surface 1211 and extends away from the frame body in the height direction, and the body portion 121 and the limiting portion 122 form a mounting area for mounting the laminated piece; the limiting portion 122 is provided with a limiting end 1221 away from the body portion 121, and an inner inclined surface 1221a of the limiting end 1221 is arranged towards the mounting area and is arranged at an acute angle with the supporting surface 1211; when the laminated piece is mounted on the frame, the first protrusion 1212 abuts against the ground of the laminated piece to push the laminated piece upwards, so that the laminated piece is prevented from being too low below the frame; the inner inclined surface 1221a abuts against the top surface of the laminated piece at an inclined angle to press the laminated piece downwards, so that the laminated piece is prevented from protruding out of the frame; therefore, the frame provided in the embodiment of the present application performs bidirectional limiting on the laminated piece in the height direction, so that the laminated piece is prevented from being too low below the frame or protruding out of the frame during the frame mounting process. In the embodiment, the glass front plate of the laminated piece does not protrude out of the frame in at least a part of the long frame 10, and the frame effectively protects the glass front plate, so that the glass front plate is prevented from being broken due to collision during transportation and installation. On the other hand, the protrusion 1212 abuts against the bottom surface of the laminated piece, so that the height of the glass front plate is prevented from being too low below the frame, which is helpful to reduce water accumulation in the part of the frame and is beneficial to avoid the generation of water accumulation and subsequent dust accumulation.

[0053] In the embodiment, the body portion 121 is formed with a second cavity C12, and the second section 32 is embedded in the second cavity C12, so that the body portion 121 is connected with the first frame section 110 through the first corner code 30.

[0054] In the technical scheme of the embodiment of the present application, as shown in Figure 1 the first frame section 110 extends along a first direction and has a first end surface S11 and a first cavity C11 formed inside the first frame section 110 along the first direction from the first end surface S11.

[0055] the second frame section 120 extends along the first direction and has a second end surface S12 and a second cavity C12 formed inside the second frame section 120 along the first direction from the second end surface S12; the second end surface S12 abuts against the first end surface S11.

[0056] the first corner code 30 has a first section 31 extending along the first direction and a second section 32 extending along the first direction; the first section 31 is connected with the second section 32; the first section 31 is embedded in the first cavity C11, and the second section 32 is embedded in the second cavity C12; the first section 31 abuts against the second frame section 120 or the second section 32 abuts against the first frame section 110.

[0057] In this embodiment, the long frame 10 includes a first frame segment 110 and a second frame segment 120; both the first frame segment 110 and the second frame segment 120 extend along a first direction and have a first end face S11 and a second end face S12, respectively, and have a first cavity C11 formed extending from the first end face S11 inward along the first direction and a second cavity C12 formed extending from the second end face S12 inward along the first direction, respectively; the first frame segment 110 and the second frame segment 120 are connected by a first corner bracket 30, and the first end face S11 and the second end face S12 abut against each other. The first frame segment 110 and the second frame segment 120 are joined together to form a long frame 10. Moreover, the first segment 31 of the first corner bracket 30 abuts against the second frame segment 120 or the second segment 32 abuts against the first frame segment 110. When the first corner bracket 30 is installed, the first corner bracket 30 is self-positioned by the second frame segment 120 or the first frame segment 110, without the need to set an external limiting structure. This overcomes the technical problem of inconsistent appearance of the long frame 10 caused by setting an external limiting structure, so that the appearance of the long frame 10 is consistent and continuous, and the aesthetics of the long frame 10 are improved.

[0058] It should be noted that the cross-sectional dimensions and shape of the first segment 31 match the cross-sectional dimensions and shape of the first cavity C11; the cross-sectional dimensions and shape of the second segment 32 match the cross-sectional dimensions and shape of the second cavity C12. That is, after the first corner bracket 30 is embedded in the first cavity C11 and the second cavity C12 respectively, the first corner bracket 30 is fixed relative to the first frame segment 110 and the second frame segment 120.

[0059] In this embodiment, the first corner code 30 is a right-angle code extending along the first direction.

[0060] As an optional implementation of the above embodiments, the width of the first segment 31 is greater than the width of the second segment 32, so that the first segment 31 abuts against the second end face S12. Figure 5 From the perspective shown (displaying the linear structure of the first corner bracket 30), the first corner bracket 30 is divided into a narrower second segment 32 and a wider first segment 31. During installation, the narrower second segment 32 is first inserted into the second cavity C12. Since the first segment 31 is wider, when the wider first segment 31 abuts against the second end face S12, the first corner bracket 30 is positioned, thus eliminating the need for an external limiting structure for positioning. Then, the wider first segment 31 is assembled with the second cavity C12 to achieve the assembly of the long frame 10.

[0061] like Figure 4As shown, the width of the second cavity C12 of the second frame segment 120 is smaller than the width of the first cavity C11 of the first frame segment 110. For example, in some embodiments, the second frame segment 120 is located between two first frame segments 110, and the width of the first section 31 is greater than the width of the second section 32, so that the first section 31 abuts against the second end surface S12.

[0062] In some other embodiments, the width of the second cavity C12 of the second frame segment 120 is greater than the width of the first cavity C11 of the first frame segment 110. For example, in some embodiments, the second frame segment 120 is located between two first frame segments 110, and the width of the first section 31 is smaller than the width of the second section 32, so that the second section 32 abuts against the first end surface S11.

[0063] In some other embodiments, the side surface of the first section 31 can be provided with a positioning block, and the second section is provided with a positioning groove. During installation, the positioning block is first inserted into the second cavity, and then the positioning block is clamped into the positioning groove, so that the positioning block on the first section of the first corner code abuts against the positioning groove of the second section, and the first corner code is self-positioned by the second section.

[0064] As an optional implementation of the above embodiments, as shown in Figure 4 As shown, the first end surface S11 is inclined to the first direction, and the second end surface S12 is inclined to the first direction. In embodiments, the first frame segment 110 and the second frame segment 120 are mitered, and the mitered surfaces of the two frame sections are not perpendicular to the first direction, but have a certain angle. The longitudinal lap length of the mitered surface is longer, and even if there is a slight gap in the actual production process, it will not cause a through gap as easily as the vertical surface, and there is a certain allowance for the joint gap, which is more advantageous in terms of aesthetics. In addition, for the vertical surface lap, the force transmission plane of the two frame sections is on the vertical surface of the first corner code 30 cut by the joint surface. For a first corner code 30 with a certain width, the vertical surface is the smallest cross section, and this way will cause more concentrated stress on this cross section. Therefore, compared with the vertical surface lap, in the case of mitered lap, the shear force transmission section of the first corner code 30 is larger than the vertical surface, which reduces the stress concentration of the component and improves the stress environment, which has a good gain for increasing the overall structural safety of the frame.

[0065] That is, in embodiments, the first end surface S11 and the second end surface S12 abut to form a joint surface, and the angle between the joint surface and the first direction is 15 to 90° (not 90°).

[0066] As an optional implementation of the above embodiments, in combination with Figure 1As shown, the long side frame 10 comprises two first frame segments 110, the second frame segment 120 is arranged between the two first frame segments 110, and any first frame segment 110 and the second frame segment 120 are connected through the first corner code 30; or

[0067] The long side frame 10 comprises two second frame segments 120, the first frame segment 110 is arranged between the two second frame segments 120, and any second frame segment 120 and the first frame segment 110 are connected through the first corner code 30.

[0068] That is, in the technical scheme of the embodiment of the present application, the long side frame 10 can be arranged with the second frame segment 120 between the two first frame segments 110, or arranged with the first frame segment 110 between the two second frame segments 120.

[0069] For example, the second frame segment 120 is arranged without an A surface. The long side frame 10 can be arranged with the second frame segment 120 without an A surface between the two first frame segments 110 with an A surface. In this embodiment, that is, the two ends of the long side frame 10 adopt the reinforced section with bolt holes on the A surface and C surface; and the second frame segment 120 without an A surface is arranged between the two first frame segments 110 with an A surface. The two first frame segments 110 with an A surface ensure the structural strength of the long side frame 10 and also reserve the installation mode of the two first frame segments 110 through the pressure block, and also enable the middle segment to adopt the dust-proof form without an A surface. In this case, the assembly can maximize the dust-proof function under the conditions of horizontal and vertical installation, and also can be installed in a universal pressure block or bolt installation mode.

[0070] The long side frame 10 can also be arranged with the first frame segment 110 with an A surface between the two second frame segments 120 without an A surface.

[0071] In a second aspect, as shown, the embodiment of the present application also proposes a combined frame 1 comprising a long side frame 10 and a short side frame 20. The long side frame 10 adopts at least one part of the technical scheme or all of the technical scheme of the foregoing embodiment. The short side frame 20 extends along a second direction, and the short side frame 20 is connected with the first frame segment 110 through a second corner code 40, or the short side frame 20 is connected with the second frame segment 120 through the second corner code 40. Figure 1 In the embodiment, the first direction is the length direction, and the second direction is the width direction. The long side frame 10 has two and is arranged opposite in the width direction; the short side frame 20 has two and is arranged opposite in the length direction. The short side frame 20 and the long side frame 10 are connected through the second corner code 40.

[0072]

[0073] ​In some embodiments, the long side frame 10 can be formed by splicing two first frame segments 110 with A faces and a second frame segment 120 without an A face. In this structure, the short side frame 20 is connected to the first frame segment 110 through the second corner code 40.

[0074] In some embodiments, the long side frame 10 can be formed by splicing two second frame segments 120 without A faces and a first frame segment 110 with an A face. In this structure, the short side frame 20 is connected to the second frame segment 120 through the second corner code 40.

[0075] In embodiments, as shown in FIG. 4, the second corner code 40 is an L-shaped corner code. A cutting groove is made on the inside corner of the second corner code 40 along the first frame axis, so that the short side frame 20 can move further inward to reduce the gap between the short side frame 20 and the laminated piece due to the tolerance fit, and the short side frame 20 and the laminated piece are adaptively fitted. Figure 6

[0076] In some embodiments, the cross-sectional shape of the short side frame 20 can also be set as the cross-sectional shape of the second frame segment 120 without an A face, that is, the short side frame 20 can also be set as a non-dust-collecting structure.

[0077] The embodiments of the present application also propose a photovoltaic module, which comprises a laminated piece and a long side frame 10 or a combined frame 1. The long side frame 10 or the combined frame 1 adopts at least one or all of the technical solutions of the above-mentioned embodiments.

The quadrilateral laminated piece is installed on the combined frame 1 or the long side frame 10; the long side frame 10 and the short side frame 20 surround the periphery of the laminated piece and are connected to each other to fix the laminated piece.
