The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0075] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0076] See also Figure 1 This embodiment provides a mounting structure 100 for a photovoltaic module, comprising a first supporting member 10, a first fixing base 20 and a locking member 30 that cooperate with each other. Figure 2 , Figure 3 and Figure 4The first support member 10 includes a support portion 11 and an assembly portion 13. The first fixed base 20 is provided with an assembly groove 24, and the assembly portion 13 is arranged in the assembly groove 24. The locking member 30 is detachably arranged in the assembly groove 24, and the opposite sides of the locking member 30 are respectively against the first fixed base 20 and the assembly portion 13. A mortise and tenon matching structure is formed between the first support member 10, the first fixed base 20 and the locking member 30, so as to lock the relative position between the first support member 10 and the first fixed base 20 by means of interference fit, and then the first support member 10 and the first fixed base 20 can be quickly unlocked by pushing the locking member 30 out of the installation space.

[0077] In some embodiments, the first fixed base 20 includes a main body 21, a first positioning portion 22, and a second positioning portion 23, wherein the first positioning portion 22 is connected to one side of the main body 21, the second positioning portion 23 is connected to an end of the first positioning portion 22 away from the main body 21, and the second positioning portion 23 is arranged opposite to the main body 21. The assembly groove 24 is formed between the main body 21, the first positioning portion 22, and the second positioning portion 23. The assembly groove 24 is an open groove structure so that the assembly portion 13 and the locking member 30 can enter and exit the assembly groove 24 from the opening of the assembly groove 24. When the assembly portion 13 is inserted into the assembly groove 24, the locking member 30 can be inserted between the second positioning portion 23 and the assembly portion 13, and the opposite sides of the locking member 30 are respectively against the second positioning portion 23 and the assembly portion 13. In other embodiments, the locking member 30 can also be inserted between the assembly portion 13 and the main body portion 21, and the opposite sides of the locking member 30 are respectively against the assembly portion 13 and the main body portion 21, so as to satisfy the locking and positioning relationship between the locking member 30, the first support member 10 and the first fixed base 20. The present application is not limited to this.

[0078] In the embodiment of the present application, the first positioning portion 22 and the second positioning portion 23 are generally in a flat plate structure, so that the first positioning portion 22 and the second positioning portion 23 are connected to form an L shape. In other embodiments, the first positioning portion 22 and the second positioning portion 23 may also be in an arc structure, so that the first positioning portion 22 and the second positioning portion 23 are connected to form a C shape, etc. The arrangement of the first positioning portion 22 and the second positioning portion 23 only needs to meet the design requirements of the assembly slot 24, and the present application is not limited thereto.

[0079] In some embodiments, a groove 25 is provided on one side of the main body 21 facing the second positioning portion 23. The groove 25 is provided on the upper surface of the main body 21 and is disposed adjacent to the first positioning portion 22. The opening of the groove 25 is located in the assembly groove 24 so that the groove 25 is connected to the assembly groove 24. A positioning protrusion 131 is provided at one end of the assembly portion 13 disposed in the assembly groove 24 so that the end of the assembly portion 13 forms a hook-shaped structure. When the groove 25 is provided on the upper surface of the main body 21, the positioning protrusion 131 protrudes toward the main body 21, and the positioning protrusion 131 is received in the groove 25 to limit the assembly portion 13 and prevent the assembly portion 13 from slipping off the first fixed base 20. At this time, the locking member 30 is held between the assembly portion 13 and the second positioning portion 23.

[0080] In other embodiments, the groove 25 may also be provided on the side of the second positioning portion 23 facing the main body 21. At this time, the positioning protrusion 131 at the end of the assembly portion 13 protrudes toward the second positioning portion 23 to cooperate with the groove 25 on the lower surface of the second positioning portion 23, and the locking member 30 is held between the assembly portion 13 and the main body 21.

[0081] In some embodiments, the first support member 10 further includes a connecting portion 12, a supporting portion 11 is disposed at one end of the connecting portion 12, and a mounting portion 13 is disposed at the other end of the connecting portion 12, and the supporting portion 11 is disposed opposite to the mounting portion 13. When the mounting portion 13 is inserted into the mounting groove 24, the connecting portion 12 is opposite to and spaced from the end of the second positioning portion 23, and the supporting portion 11 is located above the second positioning portion 23, and the supporting portion 11 is spaced from the second positioning portion 23.

[0082] See also Figures 1 to 4 , the height a of the assembly groove 24 is greater than the height b of the positioning protrusion 131, that is, a>b, so that the assembly portion 13 can be inserted into the assembly groove 24, and the positioning protrusion 131 is matched with the groove 25. Along the width direction of the second positioning portion 23, that is Figure 1 In the horizontal direction shown, the width c of the assembly portion 13 is greater than or equal to the width d of the second positioning portion 23, that is, c≥d, so as to avoid the second positioning portion 23 abutting against the connecting portion 12 and causing the positioning protrusion 131 to be unable to cooperate with the groove 25. The width e of the groove 25 is greater than or equal to the width f of the positioning protrusion 131, that is, e≥f, so that the positioning protrusion 131 can be smoothly inserted into the groove 25, reducing the difficulty of assembly. The side wall of the groove 25 is used to resist the positioning protrusion 131 to prevent the assembly portion 13 of the first support member 10 from slipping off the assembly groove 24. When the locking member 30 is placed in the assembly groove 24 and is interference-fitted with the second positioning portion 23 and the assembly portion 13, the relative position of the first support member 10 and the first fixed base 20 is locked, and the positioning protrusion 131 cannot move in the groove 25.

[0083] In one embodiment of the present application, the locking member 30 is an annular structure, which may be a circular ring structure, a square ring structure, a polygonal ring structure, etc., but the present application is not limited thereto. In the direction away from the first positioning portion 22, the inner diameter g of the locking member 30 is greater than or equal to the width d of the second positioning portion 23, that is, g ≥ d, so that the locking member 30 can pass over the second positioning portion 23 and enter the assembly groove 24 from the gap between the second positioning portion 23 and the connecting portion 12. If the locking member 30 is inserted between the assembly portion 13 and the main body 21, the annular locking member 30 can be inserted from the support portion 11 and move toward each other along the connecting portion 12 to between the assembly portion 13 and the main body 21.

[0084] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, after the first support member 10 is matched with the first fixed base 20, the locking member 30 of the annular structure is inserted from above the second positioning portion 23, so that one side of the locking structure enters the assembly groove 24. The locking member 30 is pulled toward the first positioning portion 22 in the assembly groove 24 until it is interference-fitted with the second positioning portion 23 and the assembly portion 13, thereby locking the entire installation structure 100. Figure 5 The direction indicated by the middle arrow is the pulling direction of the locking member 30. When the mounting structure 100 needs to be disassembled, the locking member 30 is pushed in the reverse direction to move the locking member 30 out of the assembly slot 24, so that the first support member 10 and the first fixing base 20 can be unlocked.

[0085] Furthermore, please combine Figures 1 to 5, when the assembly portion 13 is inserted into the assembly groove 24 and abuts against the first positioning portion 22, the distance between the end of the second positioning portion 23 and the connecting portion 12 is the minimum assembly distance i between the two. Along the direction away from the first positioning portion 22, the thickness h between the inner ring and the outer ring of the locking member 30 is less than or equal to the minimum assembly distance i between the end of the second positioning portion 23 and the connecting portion 12, that is, h≤i, to ensure that the locking member 30 can be smoothly inserted into the assembly groove 24 of the first fixed base 20. Along the height direction of the first positioning portion 22, the height b of the positioning protrusion 131 is the distance between the surface of the side of the assembly portion 13 away from the positioning protrusion 131 and the top surface of the positioning protrusion 131. The sum of the height b of the positioning protrusion 131 and the height j of the locking member 30 is greater than or equal to the sum k of the depth of the groove 25 and the height of the assembly groove 24, that is, b+j≥k. After the locking member 30 enters the assembly groove 24, an interference fit between the first support member 10, the first fixed base 20 and the locking member 30 can be achieved. When the interference is ≥ 0 mm, that is, when b+j=k, the locking assembly requirements between the first support member 10, the first fixed base 20 and the locking member 30 can also be met. When b+j>k, the first support member 10, the first fixed base 20 and the locking member 30 are affected by the interference, and can be kept relatively fixed under the action of the elastic deformation force of the material, and will not be easily loosened.

[0086] In one embodiment of the present application, a guide portion 231 is provided at one end of the second positioning portion 23 away from the first positioning portion 22, and the thickness of the guide portion 231 gradually decreases in the direction away from the first positioning portion 22. Specifically, the inclined surface of the lower surface of the guide portion 231 is higher on the outside and lower on the inside. In this way, the end of the second positioning portion 23 can form a chamfered structure at the opening of the assembly groove 24, which facilitates the locking member 30 to enter the assembly groove 24, further reducing the difficulty of installation.

[0087] In an optional embodiment, a glue groove 111 is provided on the side of the support portion 11 away from the assembly portion 13, and the glue groove 111 is used to contain colloid to bond the photovoltaic panel 201. Specifically, the middle section structure of the support portion 11 is bent toward the first fixed base 20 to form the glue groove 111 on the upper side of the support portion 11. In other embodiments, the glue groove 111 can also be directly formed on the upper side of the support portion 11 by subtractive processing. The provision of the glue groove 111 can increase the thickness of the colloid between the first support member 10 and the photovoltaic panel 201, thereby improving the bonding firmness.

[0088] In some embodiments, one end of the support portion 11 away from the connecting portion 12 is bent toward the assembly portion 13 to form a bent portion 112. After the first support member 10 is bonded to the photovoltaic panel 201, the bent portion 112 can prevent the top of the support portion 11 from abutting against the photovoltaic panel 201. When the photovoltaic panel 201 is affected by wind, the photovoltaic panel 201 can be better protected and the risk of the photovoltaic panel 201 being broken can be reduced. In the embodiments of the present application, the adhesive groove 111 and the bent portion 112 can exist at the same time. In other embodiments, the adhesive groove 111 can also be eliminated, and the side of the support portion 11 away from the assembly portion 13 is roughly a plane, and the bent portion 112 is only provided at the end, so as to increase the support area of ​​the support portion 11 for the photovoltaic panel 201.

[0089] See also Figure 6 In one embodiment, the number of the assembly parts 13 is two, and the two assembly parts 13 are symmetrically distributed on opposite sides of the first support member 10. Specifically, the two assembly parts 13 are symmetrically arranged on opposite sides of the connecting part 12, so that the first support member 10 can cooperate with the first fixed base 20 in a positive or reverse direction, thereby improving the versatility of the first support member 10. Optionally, the number of the support parts 11 can also be two, and the two support parts 11 are symmetrically distributed on opposite sides of the first support member 10. Specifically, the two support parts 11 are symmetrically arranged on opposite sides of the connecting part 12, and the first support member 10 is generally in an I-shaped structure as a whole, which is conducive to increasing the support area of ​​the support part 11 and improving the connection reliability between the first support member 10 and the photovoltaic panel 201. Figure 6 Other structures of the mounting structure 100 of the embodiment shown are Figure 1 The embodiments shown are substantially the same and will not be described in detail here.

[0090] See also Figure 7 In one embodiment, the mounting structure 100 further includes a positioning frame 40, and the positioning frame 40 is connected to one end of the support portion 11 away from the connection portion 12. The positioning frame 40 is used to fix the photovoltaic panel 201. The positioning frame 40 and the support portion 11 may be fixedly connected or detachably connected, so as to improve the versatility of the mounting structure 100. Specifically, the positioning frame 40 includes a first frame 41 and a second frame 42, and the first frame 41 is connected to one end of the support portion 11 away from the connection portion 12, and the connection between the first frame 41 and the end of the support portion 11 may be fixedly connected or detachably connected. The second frame 42 is connected to one end of the first frame 41 away from the support portion 11, and the second frame 42 is arranged opposite to the support portion 11. The edge of the photovoltaic panel 201 can be installed between the support portion 11, the first frame 41 and the second frame 42.

The back of the photovoltaic panel 201 is bonded and fixed to the support portion 11 of the first support member 10 in the mounting structure 100. Only the mounting structure 100 is provided with a locking member 30, and at least one second support member 10' cooperates with at least one second fixed base 20', but no locking member 30 is provided between the two, so as to adapt to the assembly tolerance of the photovoltaic panel 201. In other embodiments, the photovoltaic assembly 200 may further include at least two groups of mounting structures 100, that is, a locking member 30 may be assembled between each pair of first support members 10 and first fixing bases 20. During installation, the locking member 30 of the next group of mounting structures 100 needs to be assembled after the locking member 30 of the previous group of mounting structures 100 is assembled, so as to avoid the problem of jamming.

[0099] In other embodiments, the number of second fixed bases 20', the number of second support members 10' and the number of mounting structures 100 can also be set according to actual needs, and the present application is not limited thereto. The long strip-shaped support members are placed horizontally and cooperate with at least two fixed bases in each row at the same time to simplify the assembly process.

[0101] During the actual installation process, the roof conditions are complicated and the roof is often uneven. When at least two second fixed bases 20' and / or the first fixed base 20 are installed on the roof outer panel 301, the installation positions are not on the same horizontal plane. After installation, at least two second fixed bases 20' and the first fixed base 20 are in an ups and downs state. In order to allow the first support member 10 or the second support member 10' fixed on the photovoltaic panel 201 to be smoothly assembled with the at least two second fixed bases 20' and / or the first fixed base 20, it is necessary to constrain the matching tolerance of the first fixed base 20 and / or the second fixed base 20'.

In each row of fixing bases, the assembly tolerance of at least two second fixing bases 20' and / or the first fixing base 20 in the thickness direction of the roof outer plate 301 is set to a first assembly tolerance m, and the range of m is 0-10mm, such as 0mm, 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc. Preferably, it is 5mm. The sum of the first assembly tolerance m and the height b of the positioning protrusion 131 is less than or equal to the height a of the assembly groove 24 on the first fixed base 20, that is, m+b≤a. Therefore, when the locking member 30 in the installation structure 100 can be smoothly assembled between the corresponding first fixed base 20 and the first support member 10, it is ensured that the first support member 10 can simultaneously enter the assembly groove 24 of at least two second fixed bases 20' and the first fixed base 20, thereby meeting the assembly requirements of the photovoltaic panel 201 in the thickness direction of the roof outer panel 301.

The assembly tolerance of the first fixed base 20 and / or the second fixed base 20' in the direction parallel to the surface of the roof outer panel 301 is set to the second assembly tolerance n, and the range of n is 0-6mm, such as 0mm, 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, etc. It is preferably 3mm. The sum of the second assembly tolerance n and the width f of the positioning protrusion 131 is less than or equal to the width e of the groove 25, that is, n+f≤e, thereby ensuring that the first support member 10 can simultaneously enter the groove 25 of at least two second fixed bases 20' and / or the first fixed base 20, meeting the assembly requirements of the photovoltaic panel 201 in the direction parallel to the surface of the roof outer panel 301.
