[0100] In some examples, the first connecting part 111 can be located between the first sub-branch 1141 and the second sub-branch 1142.

[0101] In some examples, the first connecting part 111 can be located on the line connecting the first sub-branch 1141 and the second sub-branch 1142 arranged in the second direction. In this way, the force acting on the first sub-branch 1141 and the second sub-branch 1142 and the force acting on the first connecting part 111 and the fixing part 221 are on a straight line, the uniformity of the force acting on the first connecting member 11 can be improved, the stability of the first connecting member 11 connecting the fixing part 221 can be improved, and thus the stability of the installation of the photovoltaic module 20 can be improved.

[0102] In some examples, the first connecting part 111 can be located on the side of the line connecting the first sub-branch 1141 and the second sub-branch 1142 arranged in the second direction. In this way, after the second connecting member 12 connects the first connecting member 11 to the purlin 30 through the first sub-branch 1141 and the second sub-branch 1142, the first sub-branch 1141 and the second sub-branch 1142 can exert uniform force on the first connecting member 11 on both sides of the first connecting part 111, the stability of the second connecting member 12 connecting the first connecting member 11 can be improved, the stability of the second connecting member 12 connecting the first connecting member 11 can be improved, and thus the stability of the installation of the photovoltaic module 20 can be improved.

[0103] In some examples, with reference toFigure 5 As shown, the first connecting part 111 can include a first sub-part 1111 and a second sub-part 1112. The first sub-branch arm 1141 and the second sub-branch arm 1142 can be located between the first sub-part 1111 and the second sub-part 1112. The arrangement direction of the first sub-part 1111 and the second sub-part 1112 intersects the second direction. That is, in some examples of the embodiments of the present application, the arrangement direction of the first sub-part 1111 and the second sub-part 1112 can intersect the arrangement direction of the first sub-branch arm 1141 and the second sub-branch arm 1142.

[0104] In some examples, the first sub-part 1111 can be located on one side of the line connecting the first sub-branch arm 1141 and the second sub-branch arm 1142. The second sub-part 1112 can be located on the other side of the line connecting the first sub-branch arm 1141 and the second sub-branch arm 1142.

[0105] In some examples, the first sub-part 1111 and the second sub-part 1112 can be symmetrical with respect to the line connecting the first sub-branch arm 1141 and the second sub-branch arm 1142.

[0106] In some examples of the embodiments of the present application, by setting the first connecting part 111 to include the first sub-part 1111 and the second sub-part 1112, and setting the first sub-branch arm 1141 and the second sub-branch arm 1142 to be located between the first sub-part 1111 and the second sub-part 1112, the arrangement direction of the first sub-part 1111 and the second sub-part 1112 is set to intersect the second direction. In this way, after the second connecting piece 12 connects the first connecting piece 11 through the first sub-branch arm 1141 and the second sub-branch arm 1142, the first sub-part 1111 and the second sub-part 1112 are clamped with the fixed part 221, and the first sub-part 1111 and the second sub-part 1112 can provide force to the first connecting piece 11 from both sides of the second connecting piece 12. In this way, the force balance of the first connecting piece 11 can be improved, and the stability of the connection of the photovoltaic module 20 can be improved.

[0107] Figure 6 is another overall structure schematic view of the first connecting piece in the connecting assembly provided by some embodiments of the present application.

[0108] In some examples, with reference to Figure 6 As shown, the first connecting part 111 includes a first sub-part 1111 and a second sub-part 1112, and the connecting branch arm 114 is located between the first sub-part 1111 and the second sub-part 1112; the arrangement direction of the first sub-part 1111 and the second sub-part 1112 intersects the second direction.

[0109] It can be understood that, as described in detail in the foregoing embodiments of the present application, the connecting arm 114 can include a first sub-arm 1141 and a second sub-arm 1142, both of which are located between the first sub-portion 1111 and the second sub-portion 1112.

[0110] In some examples, the connecting arm 114 can include one arm. For example, one independent connecting arm 114 can be increased in thickness along the second direction, so that the strength of the connecting arm 114 can be improved, and the stability of the connection of the second connecting member 12 to the first connecting member 11 can be ensured, and the stability and safety of the installation of the photovoltaic module 20 can be ensured.

[0111] In some examples, as shown in Figure 1 , Figure 2 , Figures 4-6 , the first connecting portion 111 can include a clamping hole 111a. The clamping hole 111a can be a through hole. The clamping hole 111a can pass through both surfaces of the connecting body 113 along the first direction.

[0112] In some examples, in order to facilitate the connection of the first connecting member 11 to the fixing portion 221 and the installation and fixation of the photovoltaic module 20, as shown in Figure 3 , the connecting assembly 10 can include a buckle 13. The buckle 13 can be arranged in the clamping hole 111a along the first direction and clamped to the first connecting member 11.

[0113] In some examples, the buckle 13 can be used to clamp the fixing portion 221 and the connecting body 113.

[0114] In some examples, the fixing portion 221 can be provided with a through hole, and the buckle 13 can pass through the through hole on the fixing portion 221 and the clamping hole 111a in sequence and be clamped to the side of the connecting body 113 away from the fixing portion 221, so as to clamp the fixing portion 221 and the connecting body 113.

[0115] In some examples of the embodiments of the present application, the first connecting portion 111 is provided as a clamping hole 111a. In this way, the first connecting portion 111 can be machined by only opening a through hole on the connecting body 113 along the first direction, which facilitates the machining and production of the first connecting member 11 and saves the machining and production cost of the first connecting member 11. In addition, the buckle 13 passes through the clamping hole 111a to clamp the fixing portion 221 and the connecting body 113, so that the connection of the first connecting member 11 to the fixing portion 221 can be facilitated, and the installation efficiency of the photovoltaic module 20 can be improved.

[0116] Figure 7 is a schematic diagram of an overall structure of a buckle in a connecting assembly provided by some embodiments of the present application. Figure 8is a front view of a buckle in a connecting assembly provided by some embodiments of the present application.

[0117] In some examples, with reference to Figure 7 and Figure 8 As shown in the figures, the buckle 13 part can include a third connecting part 131 and two oppositely arranged clamping parts 132.

[0118] In some examples, one end of the clamping part 132 can be provided with a clamping hook 1321. The clamping hook 1321 can be located on the side of the two clamping parts 132 away from each other. After the clamping part 132 is inserted through the clamping hole 111a, the clamping hook 1321 can be clamped on the side of the connecting body 113 away from the fixing part 221.

[0119] In some examples, along the arrangement direction of the two clamping parts 132, the distance between the sides of the two clamping parts 132 away from each other can be equal, similar or close to the hole diameter of the clamping hole 111a. Along the arrangement direction of the two clamping parts 132, the distance between the sides of the two clamping hooks 1321 away from each other can be greater than the hole diameter of the clamping hole 111a. In this way, after the two clamping parts 132 are inserted into the clamping hole 111a, it can be ensured that the clamping hook 1321 can be clamped on the side of the connecting body 113 away from the fixing part 221.

[0120] It can be understood that in some installation modes, the clamping hook 1321 can be inserted into the clamping hole 111a from the side of the connecting body 113 away from the fixing part 221, and then inserted out of the through hole on the fixing part 221, so as to clamp the fixing part 221 and the connecting body 113; at this time, the clamping hook 1321 can be clamped on the side of the fixing part 221 away from the connecting body 113.

[0121] In some examples, the third connecting part 131 can be connected to the other end of the two clamping parts 132. In this way, the ends of the two clamping parts 132 provided with the clamping hook 1321 are not connected to each other, so that the ends of the two clamping parts 132 provided with the clamping hook 1321 can have a certain activity space, and the two clamping hooks 1321 can approach each other through the activity space, facilitating the insertion of the clamping hook 1321 into the clamping hole 111a to clamp the first connecting piece 11 and the fixing part 221.

[0122] In some examples, with reference to Figure 7 and Figure 8As shown, along the arrangement direction of the two clamping portions 132, the two ends of the third connecting portion 131 can protrude from the side away from the two clamping portions 132. In this way, after the pull buckle is worn through the clamping hole 111a, the part of the third connecting portion 131 protruding from the side away from the two clamping portions 132 can abut against the side of the fixing portion 221 away from the first connecting piece 11, so that the fixing portion 221 and the first connecting piece 11 can be clamped in two directions, i.e., from the side of the fixing portion 221 away from the first connecting piece 11 through the third connecting portion 131, and from the side of the connecting body 113 away from the fixing portion 221 through the clamping hook 1321, thereby improving the stability of the clamping of the first connecting piece 11 and the fixing portion 221.

[0123] Figure 9 is another overall structure schematic view of the pull buckle in the connecting assembly provided by some embodiments of the present application. Figure 10 is another front view of the pull buckle in the connecting assembly provided by some embodiments of the present application.

[0124] In some examples, referring to Figure 9 and Figure 10 As shown, the third connecting portion 131 can include at least one deformation segment 1311. The deformation segment 1311 can be connected to at least one clamping portion 132. Figure 9 and Figure 10 are shown as specific examples in which the deformation segment 1311 is connected to two clamping portions 132.

[0125] In some examples, referring to Figure 10 As shown, along the arrangement direction of the two clamping portions 132, the maximum distance between the deformation segment 1311 and the other clamping portion 132 can be a first distance d1. It can be understood that in some examples of the embodiments of the present application, the maximum distance between the deformation segment 1311 and the other clamping portion 132 can refer to the distance between the part of the deformation segment 1311 protruding from the side away from the two clamping portions 132 and the other clamping portion 132, along the arrangement direction of the two clamping portions 132 (for example, the direction shown by the x-axis in Figure 10 .

[0126] In some examples, referring to Figure 10 As shown, the maximum distance between the two clamping portions 132 can be a second distance d2.

[0127] In some examples, the first distance d1 can be greater than the second distance d2.

[0128] In some examples of the embodiments of the present application, by setting at least part of the third connecting part 131 as a deformation section 1311 connected to at least one clamping part 132, setting the maximum distance between the deformation section 1311 and the other clamping part 132 as the first distance d1 and the maximum distance between the two clamping parts 132 as the second distance d2 along the arrangement direction of the two clamping parts 132, and setting the first distance d1 to be greater than the second distance d2, the deformation section has a larger deformation space with the other clamping part 132, and when the photovoltaic module 20 needs to be disassembled, the deformation section deforms relative to the other clamping part 132, so that the clamping hooks 1321 on the two clamping parts 132 move close to each other, the distance between the two clamping hooks 1321 decreases, and when the distance between the two clamping hooks 1321 is less than the hole diameter of the clamping hole 111a along the arrangement direction of the two clamping hooks 13, the clamping hooks 1321 can be conveniently pulled out of the clamping hole 111a, the first connecting piece 11 and the fixing part 221 can be conveniently disassembled, and the disassembly efficiency of the photovoltaic module 20 is improved.

[0129] In some examples, referring to Figure 9 and Figure 10 , the deformation section 1311 can include a first circular arc connecting part 1311a.

[0130] In some examples, the clamping hook 13 can be formed by bending a sheet metal part, and the first circular arc connecting part 1311a can be formed by bending or pressing.

[0131] In some examples, along the arc direction of the first circular arc connecting part 1311a (for example, the direction shown by arrow a-a1 in Figure 10 , one end of the first circular arc connecting part 1311a is connected to one of the clamping parts 132, and the other end of the first circular arc connecting part 1311a is connected to the other clamping part 132.

[0132] In some examples, along the arrangement direction of the two clamping parts 132, the radial dimension of the first circular arc connecting part 1311a is greater than the distance between the two clamping parts 132. In this way, the first circular arc connecting part 1311a can have a larger deformation space, facilitating the provision of a deformation space for the movement of the two clamping parts 132 towards each other, and improving the disassembly efficiency of the photovoltaic module 20.

[0133] Figure 11 is another overall structure diagram of the clamping hook in the connecting assembly provided by some embodiments of the present application. Figure 12 is another front view of the clamping hook in the connecting assembly provided by some embodiments of the present application.

[0134] In some examples, referring to Figure 11 and Figure 12As shown, the deformation section 1311 can include a first sub-section 1311b. The first sub-section 1311b can be connected with one of the clamping portions 132.

[0135] In some examples, the deformation section 1311 can include a second sub-section 1311c. The second sub-section 1311c can be connected with the other clamping portion 132.

[0136] In some examples, the deformation section 1311 can include a connecting section 1311d. The connecting section 1311d can be connected between the first sub-section 1311b and the second sub-section 1311c. The connecting section 1311d can be connected with the first sub-section 1311b and the second sub-section 1311c at ends away from the clamping portions 132.

[0137] In some examples, the first sub-section 1311b and the second sub-section 1311c can each be an arc-shaped section.

[0138] In some examples, one of the first sub-section 1311b and the second sub-section 1311c can be an arc-shaped section, and the other can be a rectangular bent section.

[0139] In some examples, one of the first sub-section 1311b and the second sub-section 1311c can be an arc-shaped section, and the other can be a bent section.

[0140] In some examples, the first sub-section 1311b and the second sub-section 1311c can each be a rectangular section.

[0141] In some examples, the first sub-section 1311b and the second sub-section 1311c can each be a bent section.

[0142] In some examples, the connecting section 1311d can extend along the arrangement direction of the two clamping portions 132.

[0143] In some examples of the embodiments of the present application, by setting the deformation section 1311 to include the first sub-section 1311b, the second sub-section 1311c, and the connecting section 1311d, the connecting section 1311d being connected between the first sub-section 1311b and the second sub-section 1311c, the first sub-section 1311b being connected with one of the clamping portions 132, and the second sub-section 1311c being connected with the other clamping portion 132. In this way, the distance between the first sub-section 1311b and the second sub-section 1311c can be increased by the connecting section 1311d, the deformation space between the first sub-section 1311b and the second sub-section 1311c is increased, the two clamping portions 132 can be moved towards each other by the deformation of the first sub-section 1311b and the second sub-section 1311c, and the photovoltaic module 20 can be easily disassembled.

[0144] In some examples, with reference to Figure 11 and Figure 12As shown, the first segment 1311b may include a second arc-shaped connecting portion. The second segment 1311c may include a third arc-shaped connecting portion. The centripetal sides of the second and third arc-shaped connecting portions may be arranged opposite to each other. Thus, the distance between the first segment 1311b and the second segment 1311c can be increased by the second and third arc-shaped connecting portions, thereby improving the deformation space of the first and second segments 1311b and 1311c. Furthermore, the second arc-shaped connecting portion can reduce abrupt bending of the first segment 1311b, resulting in a more uniform stress distribution on the first segment 1311b and extending its service life. The third arc-shaped connecting portion can also reduce abrupt bending of the second segment 1311c, resulting in a more uniform stress distribution on the second segment 1311c and extending its service life.

[0145] In some examples, refer to Figures 9-12 As shown, the latch 13 may include an unlocking part 133. The unlocking part 133 may be connected to at least one of the two latching parts 132 that is connected to the deformable segment 1311. The unlocking part 133 may be located on one side opposite to the two latching parts 132.

[0146] In some examples, the unlocking part 133 and the latching part 132 can be a single piece.

[0147] In some examples, the unlocking part 133 and the snap-fit ​​part 132 can be separate parts, and the unlocking part 133 is connected to the snap-fit ​​part 132 by means of welding, plugging or threaded connection.

[0148] In some examples, when removing the photovoltaic module 20 from the purlin 30, the unlocking part 133 can be pressed to apply a force to the latch 13 and the deformation section 1311 towards the opposite side of the two latches 13. The deformation section 1311 deforms, thereby causing the two latching parts 132 to move closer to each other and exit the slot of the purlin 30. In this way, the photovoltaic module 20 can be easily removed from the purlin 30, improving the convenience and efficiency of removing the photovoltaic module 20.

[0149] In some examples, refer to Figure 12 As shown, along the arrangement direction of the two snap-fit ​​portions 132 (e.g.) Figure 12 (In the direction shown by the x-axis), the maximum distance between the end of the unlocking part 133 away from the buckle 13 and the buckle 13 can be the third distance d3.

[0150] In some examples, the maximum distance between the end of the unlocking part 133 away from the latch 13 and the latch 13 can refer to the maximum distance between the end of the unlocking part 133 away from the latch 13 and the latch 13 connected to the current unlocking part 133 among the two latches 13.

[0151] In some examples, referring to Figure 12 As shown, along the arrangement direction of the two clamping portions 13, the maximum distance between the side of the deformation section 1311 away from the clamping portion 13 and the clamping portion 13 can be a fourth distance d4.

[0152] In some examples, the third distance d3 can be greater than the fourth distance d4.

[0153] In some examples, the third distance d3 can be equal to the fourth distance d4.

[0154] In some examples of the embodiments of the present application, along the arrangement direction of the two clamping portions 132, the maximum distance between the end of the unlocking portion 133 away from the clamping portion 13 and the clamping portion 13 is a third distance d3, and the maximum distance between the side of the deformation section 1311 away from the clamping portion 13 and the clamping portion 13 is a fourth distance d4; the third distance d3 is set to be greater than or equal to the fourth distance d4. In this way, when the photovoltaic module 20 is detached from the purlin 30, the unlocking portion 133 can be clamped from the side of the unlocking portion 133 away from the clamping portion 13, and at this time, since the third distance d3 is greater than or equal to the fourth distance d4, the end of the unlocking portion 133 away from the clamping portion 13 can be exposed outside the deformation section 1311, which facilitates the operation of the tool on the unlocking portion 133 and improves the convenience of detaching the photovoltaic module 20.

[0155] In some examples, referring to Figures 9-12 As shown, the unlocking portion 133 can be located at the end of the clamping portion 132 close to the deformation section 1311. The unlocking portion 133 can be located at the end of the clamping arm close to the deformation section 1311. In this way, the unlocking portion 133 has a certain distance from the clamping hook 1321, which can ensure that the clamping hook 1321 can be inserted into the clamping groove of the purlin 30, facilitating the fixed connection of the photovoltaic module 20 and the purlin 30. In addition, by arranging the unlocking portion 133 at the end of the clamping arm close to the deformation section 1311, the unlocking portion 133 also has a certain distance from the deformation section 1311, which can lengthen the force arm of the force applied to the deformation section 1311, and can reduce the force required to be applied to the unlocking portion 133 when unlocking through the unlocking portion 133, facilitating the detachment of the photovoltaic module 20 from the purlin 30.

[0156] In some examples, referring to Figures 9-12 As shown, the unlocking portion 133 can include two, and the two clamping portions 132 can be connected to one unlocking portion 133 respectively. In this way, the force can be applied to the unlocking portion 133 from both sides of the locking portion, which can reduce the distance that each of the two clamping portions 132 needs to move, facilitating the detachment of the photovoltaic module 20 from the purlin 30.

[0157] Figure 13is a structural schematic view of a gap compensation member in a connecting assembly provided by some embodiments of the present application. Figure 14 is a front view of a gap compensation member in a connecting assembly provided by some embodiments of the present application.

[0158] In some examples, referring to Figure 13 and Figure 14 , the connecting assembly 10 can include a gap compensation member 14. The gap compensation member 14 can be disposed between the buckle 13 and the first connecting member 11. The gap compensation member 14 can be used to compensate for the gap after the buckle 13 is clamped to the first connecting member 11 and the fixing portion 221.

[0159] In some examples, when the buckle 13 is clamped to the first connecting member 11 and the fixing portion 221, due to the machining process and the like, there can be a certain fitting gap between the first connecting member 11 and the fixing portion 221 after the buckle 13 is clamped to the first connecting member 11 and the fixing portion 221, which can cause the fixing portion 221 to be unstable in connection with the first connecting member 11, affecting the stability and safety of the installation of the photovoltaic module 20.

[0160] In some examples, when the buckle 13 is clamped to the first connecting member 11, a gap compensation member 14 can be disposed between the first connecting member 11 and the buckle 13. The gap compensation member 14 can be disposed between the first connecting member 11 and the fixing portion 221. In this way, the fitting gap between the first connecting member 11 and the fixing portion 221 can be filled by the gap compensation member 14, thereby improving the stability of the buckle 13 in clamping the fixing portion 221 to the first connecting member 11 and improving the stability of the installation of the photovoltaic module 20.

[0161] In some examples, the gap compensation member 14 can include any one of a gasket, a pad, or a rubber pad.

[0162] In some examples, the gap compensation member 14 can include an elastic member. The elastic member can abut between the buckle 13 and the first connecting member 11.

[0163] In some examples, the elastic member can include a spring gasket.

[0164] In some examples, the elastic member can include a compression spring. The elastic member can have a through hole extending in a first direction. The buckle 13 can pass through the through hole on the elastic member, the through hole on the fixing portion 221, and then pass through the clamping hole 111a, and be clamped to the first connecting member 11. At this time, the elastic member can be in a compressed state, and the restoring force of the elastic member abutting the buckle 13 and the fixing portion 221 respectively, so that the buckle 13 tightens the first connecting member 11, thereby improving the stability of the installation of the photovoltaic module 20.

[0165] In some examples, the elastic member can include a spring sheet. Referring to Figure 13 andFigure 14 As shown, the spring can have a insertion hole 141. The snap fastener 13 can be inserted into the insertion hole 141 and engaged with the first connecting part 111.

[0166] In some examples of embodiments of this application, a spring sheet is used as a gap compensation member 14; thus, after the gap compensation member 14 is provided between the buckle 13 and the first connector 11, the gap compensation member 14 abuts between the buckle 13 and the first connector 11, which can increase the contact area between the gap compensation member 14 and either the buckle 13 or the first connector 11, thereby improving the stability of the contact between the gap compensation member 14 and either the buckle 13 or the first connector 11, and improving the stability of the installation of the photovoltaic module 20.

[0167] In some examples, refer to Figure 13 and Figure 14 As shown, the spring can include a main body 142 and a bent portion 143. The main body 142 can abut against either the first connector 11 or the latch 13.

[0168] In some examples, the spring clip may be located on the side of the fixing part 221 opposite to the first connector 11. The main body part 142 may abut against the snap fastener 13.

[0169] In some examples, the spring can be positioned between the fixing part 221 and the first connector 11. The main body 142 can abut against the first connector 11.

[0170] In some examples, the bend 143 may be bent toward the other of the first connector 11 and the snap fastener 13. The angle between the bend 143 and the main body 142 may be an obtuse angle. That is, along the first direction, the size of the bend 143 may be larger than the size of the main body 142.

[0171] In some examples, the spring can be made of sheet metal, and the main body 142 and the bent part 143 can be formed by bending the sheet metal.

[0172] In some examples, refer to Figure 14 As shown, along the first direction (e.g.) Figure 14 (In the direction shown by the y-axis), the distance between the end of the bent portion 143 away from the main body portion 142 and the main body portion 142 can be a fifth distance d5. The fifth distance d5 can be greater than the mating clearance after the buckle 13 engages the first connecting member 11 and the fixing portion 221.

[0173] In some examples of the embodiments of the present application, the elastic sheet is formed by the main body 142 and the bent portion 143. The main body 142 abuts against one of the first connecting piece 11 and the buckle 13, and the bent portion 143 is bent towards the other one of the first connecting piece 11 and the buckle 13. An included angle between the bent portion 143 and the main body 142 is an obtuse angle. In this way, the main body 142 can be abutted against one of the first connecting piece 11 and the buckle 13 by the deformation of the bent portion 143. After the buckle 13 is used to connect the fixed portion 221 and the first connecting piece 11, the elastic sheet can compensate for the fitting gap between the first connecting piece 11 and the fixed portion 221, thereby improving the stability of the installation of the photovoltaic module 20.

[0174] In some examples, as shown in Figure 13 and Figure 14 , the bent portion 143 can include two bent portions 143, which are arranged at two ends of the main body 142.

[0175] In some examples, as shown in Figure 13 and Figure 14 , the elastic sheet can include an abutting portion 144. The abutting portion 144 can be connected to one end of the bent portion 143 away from the main body 142. The two bent portions 143 can be respectively connected to one abutting portion 144. That is, in the embodiments of the present application, two abutting portions 144 can be provided, and each of the two bent portions 143 can be connected to one abutting portion 144.

[0176] In some examples, the extension direction of the abutting portion 144 can be the same as, similar to, or the same as the main body 142.

[0177] In the embodiments of the present application, the abutting portion 144 is arranged at one end of the bent portion 143 away from the main body 142. In this way, after the first connecting piece 11 is connected to the fixed portion 221 by the buckle 13, the abutting portion 144 can abut against the fixed portion 221, thereby increasing the contact area of the elastic sheet and the fixed portion 221 and improving the stability of the contact between the elastic sheet and the fixed portion 221, thereby improving the stability of the installation of the photovoltaic module 20.
