[0036] Combination Figure 1 and Figure 2 As shown, the embodiment of the present application provides a frame 10, including:

[0037] The first frame segment 110 has a first end surface S11 and a first cavity C11 extending from the first end surface S11 toward the inside thereof;

[0038] The second frame segment 120 has a second end surface S12 and a second cavity C12 extending from the second end surface S12 toward the inside thereof; the second end surface S12 abuts against the first end surface S11;

[0039] The first angle code 30 includes a first section 31 and a second section 32; the first section 31 is connected to 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.

[0040] In the technical solution of the embodiment of the present application, the frame 10 includes a first frame segment 110 and a second frame segment 120; the first frame segment 110 and the second frame segment 120 respectively have a first end face S11 and a second end face S12, and respectively have a first cavity C11 extending from the first end face S11 toward the inside thereof and a second cavity C12 extending from the second end face S12 toward the inside thereof; the first frame segment 110 and the second frame segment 120 are connected by a first angle code 30, and the first end face S11 and the second end face S12 are abutted, so that the first frame segment 110 and the second frame segment 120 are connected by a first angle code 30. The frame segments 120 are spliced ​​to form the frame 10; moreover, the first segment 31 of the first corner code 30 abuts against the second frame segment 120 or the second segment 32 abuts against the first frame segment 110. When the first corner code 30 is installed, the first corner code 30 is self-positioned by the second frame segment 120 or the first frame segment 110, and there is no need to set an external limiting structure, thereby overcoming the technical problem of inconsistency in the appearance of the frame 10 caused by setting an external limiting structure, so that the appearance of the frame 10 has consistency and continuity, thereby improving the aesthetic appearance of the frame 10.

[0041] It should be noted that the cross-sectional dimensions and shape of the first section 31 match those of the first cavity C11; the cross-sectional dimensions and shape of the second section 32 match those of the second cavity C12. That is, after the first angle code 30 is respectively embedded in the first cavity C11 and the second cavity C12, the first angle code 30 is fixed relative to the first frame section 110 and the second frame section 120.

[0042] As an optional implementation of the above embodiment, Figure 2 and Figure 3As shown, the first frame segment 110 and the second frame segment 120 of the frame 10 extend in the same direction, for example, along the first direction. In this embodiment, the first frame segment 110 extends along the first direction and has a first end face S11 and a first cavity C11 extending from the first end face S11 along the first direction to form the interior thereof; the second frame segment 120 extends along the first direction and has a second end face S12 and a second cavity C12 extending from the second end face S12 along the first direction to form the interior thereof; the second end face S12 abuts against the first end face S11. In the embodiment, the first angle code 30 is a right angle code extending along the first direction. The first angle code 30 has a first section 31 extending along the first direction and a second section 32 extending along the first direction.

[0043] In this embodiment, the first direction is the length direction, that is, the frame 10 is a long frame, and includes a first frame segment 110 and a second frame segment 120; the first frame segment 110 and the second frame segment 120 both extend along the first direction, and respectively have a first end surface S11 and a second end surface S12, and respectively have a first cavity C11 extending from the first end surface S11 along the first direction toward the inside thereof and a second cavity C12 extending from the second end surface S12 along the first direction toward the inside thereof; the first frame segment 110 and the second frame segment 120 are connected by a first angle code 30, and the first end surface S11 1 and the second end face S12 are abutted against each other, so that the first frame segment 110 and the second frame segment 120 are spliced ​​to form the frame 10; moreover, the first segment 31 of the first angle code 30 is abutted against the second frame segment 120 or the second segment 32 is abutted against the first frame segment 110. When the first angle code 30 is installed, the first angle code 30 is self-positioned by the second frame segment 120 or the first frame segment 110, and there is no need to set an external limiting structure, thereby overcoming the technical problem that the external limiting structure causes the appearance of the frame 10 to be inconsistent, so that the appearance of the frame 10 has consistency and continuity, and the appearance of the frame 10 is improved.

[0044] In other embodiments, Figure 7 and Figure 8 As shown, the first frame segment 110 and the second frame segment 120 of the frame 10 are vertically arranged. It can be understood that the first frame segment 110 can be a long frame, and the second frame segment 120 can be a short frame; that is, the first corner code 30 can be an L-shaped corner code; the L-shaped corner code can abut on the first end face of the long frame, and can also abut on the second end face of the short frame to achieve self-positioning.

[0045] As an optional implementation of the above embodiment, Figure 1As shown, the frame 10 includes 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 by the first corner code 30; or;

[0046] The frame 10 includes two second frame segments 120 , the first frame segment 110 is disposed between the two second frame segments 120 , and any second frame segment 120 is connected to the first frame segment 110 via the first corner code 30 .

[0047] That is, in the technical solution of the embodiment of the present application, the frame 10 may be a frame in which the second frame segment 120 is disposed between two first frame segments 110 , or a frame in which the first frame segment 110 is disposed between two second frame segments 120 .

[0048] For example, the second frame segment 120 is a structure without an A surface. The frame 10 may be formed by splicing two first frame segments 110 with an A surface between which a second frame segment 120 without an A surface is disposed. In this embodiment, that is, the two ends of the frame 10 adopt a reinforced section with an A surface and a C surface with bolt holes; and the second frame segment 120 without an A surface is arranged between two first frame segments 110110 with an A surface. The two first frame segments 110 with an A surface ensure the structural strength of the frame 10 and also retain the method of installing the two first frame segments 110 by means of a press block, and can also adopt an anti-dust accumulation form without an A surface in the middle section. In this case, the component can maximize the anti-dust accumulation function under the conditions of horizontal and vertical installation, and can also be installed by a universal press block or bolt.

[0049] The frame 10 may also be formed by splicing two second frame segments 120 without the A surface between which a first frame segment 110 with the A surface is arranged.

[0050] As an optional implementation of the above embodiment, 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. Figure 3 In the perspective shown (showing the straight-line structure of the first angle code 30), the first angle code 30 is divided into a narrower second section 32 and a wider first section 31. During installation, the narrower second section 32 is first embedded into the second cavity C12. Since the first section 31 is wider, when the wider first section 31 abuts against the second end surface S12, the first angle code 30 is positioned, and no external limiting structure is required for positioning; then the wider first section 31 is assembled with the second cavity C12 to achieve the assembly of the frame 10.

[0051] like Figure 2As shown, the width of the second cavity C12 of the second frame segment 120 is smaller than the frame segment of the first cavity C11 of the first frame segment 110. For example, in some embodiments, the second frame segment 120 is located on two first frame segments 110, and 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 surface S12.

[0052] 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 segment 31 is less than the width of the second segment 32, so that the second segment 32 abuts against the first end surface S11.

[0053] In some other embodiments, a positioning block can be provided on the side of the first section 31, and a positioning groove can be provided on the second frame section; during installation, the second section is first embedded into the second cavity, and the positioning block is inserted into the positioning groove, so that the positioning block on the first section of the first angle code abuts against the positioning groove of the second frame section, and the first angle code is self-positioned by the second frame section.

[0054] Alternatively, a positioning block is disposed on the side of the second section 32, and a positioning groove is disposed on the second frame section, and the positioning block cooperates with the positioning groove.

[0055] As an optional implementation of the above embodiment, the second end surface S12 includes two parts located on opposite sides of the cavity opening of the second cavity C12, and the first section 31 at least abuts against the two parts on opposite sides of the cavity opening of the second cavity C12, and the first section 31 at least abuts against one of the two parts. For example, in the embodiment, the first section 31 abuts against opposite sides of the cavity opening of the second cavity C12, so that the positioning of the angle code is more reliable. The cavity opening of the second cavity C12 is the entrance for the second section 32 to be embedded in the second cavity C12; during installation, when the first section 31 abuts against opposite sides of the cavity opening of the second cavity C12, the first angle code 30 is self-positioned and the first angle code 30 is not allowed to continue to move. In some embodiments, such as Figure 2 As shown, the first section 31 abuts against one side of the cavity opening of the second cavity C12.

[0056] In some embodiments, the first end surface S11 includes two parts located on opposite sides of the cavity opening of the first cavity C11, and the second section 32 at least abuts against one of the two parts on opposite sides of the cavity opening of the first cavity C11.

[0057] As an optional implementation of the above embodiment, Figure 2As shown, the first end face S11 is inclined with the first direction, and the second end face S12 is inclined with the first direction. In the embodiment, the first frame segment 110 and the second frame segment 120 are spliced ​​by bevels, and the splicing bevels of the two frames are not perpendicular to the first direction, but there is a certain angle. The longitudinal overlap length of the bevel is longer, and even if there is a slight gap in the actual production process, it will not easily cause a through gap like the vertical section, and there is a certain tolerance for the splicing gap, which is more advantageous in terms of aesthetics. In addition, for the vertical section overlap, the plane of force conduction of the two frame segments is on the vertical plane of the first angle code 30 cut out of the splicing surface. For the first angle code 30 with a certain width, the vertical section is the section with the smallest area, and this method will cause more concentrated stress on this section. Therefore, compared with the vertical section overlap, in the case of the bevel overlap, the shear force conduction section of the first angle code 30 is larger than the vertical section. This situation will reduce the stress concentration of the component, improve the force environment, and have a good gain in increasing the overall structural safety of the frame.

[0058] That is, in the embodiment, the first end surface S11 and the second end surface S12 are in contact with each other to form a joint surface, and the angle between the joint surface and the first direction is 15 to 90° (not 90°).

[0059] In some embodiments, Figure 4 The cross-sectional schematic diagram of the first frame segment 110 is shown, and the segment has an A surface 111, a B surface 113 and a C surface 112. In an embodiment, a pressing block or a bolt hole may be provided at the C surface of the first frame segment 110. In some embodiments, the first frame segment 110 may also be provided with a structure without an A surface, and a bolt hole may be provided at the C surface.

[0060] like Figure 5 The cross-sectional schematic diagram of the second frame segment 120 without the A surface is illustrated, and the segment only has the B surface and the C surface. In this structure, the second frame segment 120 is set as a segment without the A surface to reduce dust accumulation and improve the light energy utilization rate of the photovoltaic module. In some embodiments, the width of the C surface of the second frame segment without the A surface segment can be set smaller than the width of the C surface of the first frame segment to save material costs and achieve maximum optimization of structural materials.

[0061] In some embodiments, the second frame segment 120 may also be configured as a frame segment without a C-surface, so that the cross-sectional area of ​​the frame 10 may be thinned to reduce material costs.

[0062] In some embodiments, the second frame segment 120 may be configured to have only a B-side structure, that is, a structure without an A-side or a C-side structure.

[0063] As an optional implementation of the above embodiment, Figure 5As shown, the second cavity C12 is also provided with a reinforcing structure 130. Since the second frame segment 120 is provided without an A surface and / or a C surface, a cross-sectional area thinning setting is performed. Therefore, the reinforcing structure 130 is provided in the second cavity C12 so that the second frame segment 120 can bear sufficient load.

[0064] For example, in some embodiments, the second frame segment 120 is arranged between the two first frame segments 110; after the laminate is placed, based on the force analysis of the beam model, the part with the largest bending moment or internal force still exists in the mid-span part of the second frame segment 120; therefore, the reinforcing structure 130 is arranged in the second cavity C12 to make the bearing capacity of the second frame segment 120 sufficient. For example, in some embodiments, a section of reinforcing ribs is embedded in the second cavity C12 of the middle section of the second frame segment 120, and the cross section of the reinforcing ribs is close to the height and width of the inner wall of the third cavity. The cross section of the reinforcing ribs can be solid or hollow, and the material can also be aluminum alloy and other high-strength metals or non-metallic materials. After the reinforcing ribs are placed in a specific position in the middle section of the long side, the inner side B surface of the second frame segment 120 can also be grooved to fix the internal reinforcing ribs by interference fit.

[0065] In some embodiments, the first frame section 110 with a reinforced cross section with bolt holes on the A and C surfaces has been adopted at both ends of the frame 10, while the middle section adopts a cross section form (second frame section 120) with fewer cross sections and no A surface plus a possible shortened C surface. The strength of the middle section of the second frame section 120 at the maximum mid-span bending moment may be insufficient. Local reinforcement is performed in the cavity of the middle section frame, which can strengthen the weak points of the structure in a targeted manner, and the length of the reinforcing ribs can be adjusted to optimize the economy of the overall structure. In some cases, since the frame is split into three sections, the length of the middle section will not be too long, so the difficulty of placing the reinforcing ribs in the middle section frame will also be reduced.

[0066] As an optional implementation of the above embodiment, Figure 5 As shown, the second frame section 120 includes a body portion 121; the body portion 121 is connected to the first frame section 110; the body portion 121 has a support surface 1211, and a protrusion 1212 is formed on the support surface 1211, and the protrusion 1212 is used to abut the bottom surface of the laminate; and,

[0067] A limiting portion 122, wherein the limiting portion 122 is disposed on the supporting surface 1211 and extends away from the main body portion 121 in the height direction; the main body portion 121 and the limiting portion 122 form an installation area for installing the laminate; the limiting portion 122 has a limiting end 1221, wherein the limiting end 1221 is disposed away from the main body portion 121, and the inner side of the limiting end 1221 has an inner bevel 1221a, wherein the inner bevel 1221a faces the installation area and is disposed at an acute angle to the supporting surface 1211, and the inner bevel 1221a is used to abut against the transition bevel of the top surface of the laminate.

[0068] In the technical solution of the embodiment of the present application, the limiting portion 122 is arranged on the supporting surface 1211 and extends away from the frame in the height direction, and the main body 121 and the limiting portion 122 form an installation area for installing the laminate; the limiting portion 122 is provided with a limiting end 1221 away from the main body 121, and the inner inclined surface 1221a of the limiting end 1221 is arranged toward the installation area and is arranged at an acute angle to the supporting surface 1211; when the laminate is installed on the frame, the first protrusion 1212 abuts against the ground of the laminate to push the laminate upward, which can prevent the laminate from being too much lower than the frame; the inner inclined surface 1221a abuts against the transition angle of the top surface of the laminate to press the laminate downward to prevent the laminate from protruding from the frame; therefore, the frame provided in the embodiment of the present application performs bidirectional limiting on the laminate in the height direction, which can prevent the laminate from being too much lower than the frame or protruding from the frame during the framing process. In the embodiment, in at least a portion of the frame 10, the glass front plate of the laminate does not protrude from the frame, and the frame effectively protects it, preventing it from being bumped and broken during transportation and installation. On the other hand, since the protrusion 1212 abuts against the bottom surface of the pressing piece, the height of the glass front plate will not be too much lower than the frame, which helps to reduce water accumulation in this part of the frame, and is conducive to avoiding water accumulation and subsequent dust accumulation.

[0069] In the embodiment, a second cavity C12 is formed on the main body 121 , and the second segment 32 is embedded in the second cavity C12 , so that the main body 121 is connected to the first frame segment 110 through the first angle code 30 .

[0070] Second, as Figure 1 As shown, the embodiment of the present application further provides a mounting frame 1, comprising a frame 10. The frame 10 adopts at least a part of the technical solutions or all of the technical solutions of the above-mentioned embodiments.

[0071] In some embodiments, Figures 1 to 6As shown, the frame 10 is a long frame, that is, the frame 10 includes a first frame segment 110 and a second frame segment 120 extending in the same direction. The installation frame 1 also includes a short frame 20; the short frame 20 extends along the second direction, and the short frame 20 is connected to the first frame segment 110 through a second corner code 40, or the short frame 20 is connected to the second frame segment 120 through a second corner code 40.

[0072] In the embodiment, the first direction is the length direction, and the second direction is the width direction. There are two frames 10, which are arranged opposite to each other in the width direction; there are two short frames 20, which are arranged opposite to each other in the length direction. The short frames 20 and the frame 10 are connected by a second angle code 40.

[0073] In some embodiments, the frame 10 may be formed by splicing two first frame segments 110 with surface A and a second frame segment 120 without surface A between them. In this structure, the short frame 20 is connected to the first frame segment 110 via a second corner code 40 .

[0074] In some embodiments, the frame 10 may be formed by splicing two second frame segments 120 without surface A with a first frame segment 110 having surface A between them. In this structure, the short frame 20 and the second frame segment 120 are connected by a second corner code 40 .

[0075] In an embodiment, Figure 6 As shown, the second corner code 40 is an L-shaped corner code. A groove is cut along the axis of the first frame at the inner corner of the second corner code 40 to allow the short frame 20 to move further inward, thereby reducing the gap between the short frame 20 and the laminate due to tolerance matching, allowing the short frame 20 to be adaptively matched with the laminate.

[0076] In some embodiments, the cross-sectional shape of the short frame 20 may also be set to be the cross-sectional shape of the second frame segment 120 without the A surface, that is, the short frame 20 may also be set to be a structure that does not accumulate dust.

[0077] In other embodiments, Figure 7 and Figure 8 As shown, the first frame segment 110 and the second frame segment 120 of the frame 10 are perpendicular to each other, for example, the first frame segment 110 extends along the length direction, that is, the first frame segment 110 can be a long frame, and the second frame segment 120 extends along the width direction, that is, the second frame segment 120 can be a short frame. In this embodiment, the first corner code 30 is an L-shaped corner code.

[0078] The embodiment of the present application also proposes a photovoltaic module, which includes: a laminate; and a frame 10 or a mounting frame 1. The frame 10 or the mounting frame 1 adopts at least a part of the technical solutions or all of the technical solutions of the above-mentioned embodiments. The frame 10 or the mounting frame 1 is surrounded by the periphery of the laminate and connected to each other. The quadrilateral laminate is installed on the mounting frame 1 or the frame 10; the frame 10 and the short frame 20 are surrounded by the periphery of the laminate and connected to each other to fix the laminate. The above description is only an optional embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the specification and drawings of this application under the application concept of this application, or direct / indirect application in other related technical fields are included in the patent protection scope of this application.
