[0033] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] refer to Figures 1 to 3 As shown, an embodiment of this application provides a fixing structure 100 for fixing photovoltaic modules. The fixing structure 100 includes a pressure block 110 and a connecting rod 120.

[0035] The pressure block 110 includes a pressure block body 111, a first connector 112, and a second connector 113. The two ends of the pressure block body 111 are respectively connected to the first connector 112 and the second connector 113, and the pressure block body 111 is set at an angle to the first connector 112 and the second connector 113. The first connector 112 and the second connector 113 are arranged opposite to each other. The first connector 112 is provided with a first through hole 1121, and the second connector 113 is provided with a second through hole 1131. The pressure block 110 is used for the installation of photovoltaic modules. The pressure block 110 is pressed down to the target position of the photovoltaic module, so that the first connector 112, the second connector 113, and the pressure block body 111 together limit the photovoltaic module.

[0036] In this embodiment, the connecting rod 120 is provided with a first limiting part 121 and a second limiting part 122 at its opposite ends, and the connecting rod 120 can pass through the first through hole 1121 and the second through hole 1131 respectively. When the connecting rod 120 is rotated, the first limiting part 121 engages or disengages with the wall of the first through hole 1121, and the second limiting part 122 engages or disengages with the wall of the second through hole 1131. Correspondingly, the connecting rod 120 passes through the first through hole 1121 of the first connector 112 and the second through hole 1131 of the second connector 113. When the user rotates the connecting rod 120, the first locking groove 1212 and the second locking groove 1222 of the connecting rod 120 can engage with the first through hole 1121 and the second through hole 1131 respectively to achieve self-locking, which has better self-locking stability and pre-tightening force. Alternatively, after rotating the connecting rod 120, the first locking groove 1212 and the second locking groove 1222 can be separated from the pressure block 110, so that the connecting rod 120 can be removed after the self-locking is released, thereby realizing the installation and disassembly of the fixed structure 100. The installation and disassembly are more flexible, thereby improving the installation efficiency of the fixed structure 100.

[0037] It is understood that the fixing structure 100 can firmly fix the frame of the photovoltaic module to the support structure, such as a guide rail or bracket, through the pressure block 110 to prevent displacement or detachment caused by wind or other external forces. During installation, the pressure block body 111 is usually pressed horizontally on the top surface of the photovoltaic module frame, and then self-locked to the bracket by the connecting rod 120.

[0038] refer to Figures 1 to 3 As shown, the fixing structure 100 has a first direction X, a second direction Y, and a third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other. For example, the first direction X is taken as the length direction of the fixing structure 100, the second direction Y is taken as the height direction of the fixing structure 100, and the third direction Z is taken as the width direction of the fixing structure 100. It is understood that the above definitions are only for ease of understanding the relative positional relationships of the parts in the fixing structure 100 and should not be construed as limitations on this application.

[0039] In one embodiment, alternatively, referencing Figure 3 As shown, the connecting rod 120 is also provided with a third groove 123 and a fourth groove 124. The third groove 123 and the fourth groove 124 are both located between the first limiting part 121 and the second limiting part 122. The third groove 123 and the fourth groove 124 are provided to allow sufficient room for movement. When the connecting rod 120 rotates, the third groove 123 can correspond to the first through hole 1121 and the fourth groove 124 can correspond to the second through hole 1131, which facilitates the rotation of the connecting rod 120 relative to the pressure block 110 and avoids obstruction or jamming.

[0040] In one embodiment, alternatively, such as Figure 3 and Figure 4 As shown, the first limiting part 121 includes a first limiting boss 1211, a first engaging groove 1212, and a first stop 1213. The second limiting part 122 includes a second limiting boss 1221, a second engaging groove 1222, and a second stop 1223. The first limiting boss 1211 is located between the first engaging groove 1212 and the third groove 123, and the second limiting boss 1221 is located between the second engaging groove 1222 and the fourth groove 124. Correspondingly, the connecting rod 120 can move between the first through hole 1121 and the second through hole 1131. When the first locking groove 1212 of the connecting rod 120 corresponds to the first through hole 1121 and is locked into the hole wall of the first through hole 1121, the first limiting boss 1211 and the first stop block 1213 together limit the hole wall of the first through hole 1121. The second locking groove 1222 of the connecting rod 120 corresponds to the second through hole 1131 and is locked into the hole wall of the second through hole 1131. The second limiting boss 1221 and the second stop block 1223 together limit the hole wall of the second through hole 1131, thereby realizing the self-locking of the connecting rod 120 and the pressure block 110 and ensuring the stability of the fixed structure 100.

[0041] In summary, the pressure block 110 of the fixing structure 100 is used for the installation of photovoltaic modules. The pressure block 110 is pressed down to the target position of the photovoltaic module, so that the first connector 112, the second connector 113 and the pressure block body 111 together limit the photovoltaic module. The connecting rod 120 passes through the first through hole 1121 of the first connector 112 and the second through hole 1131 of the second connector 113 respectively. When the user rotates the connecting rod 120, the first locking groove 1212 and the second locking groove 1222 of the connecting rod 120 can respectively engage with the first through hole 1121 and the second through hole 1131 to achieve self-locking, which has good self-locking stability and pre-tightening force. Alternatively, after rotating the connecting rod 120, the first locking groove 1212 and the second locking groove 1222 can be separated from the pressure block 110, so that the connecting rod 120 can be removed after releasing the self-locking. This realizes the installation and disassembly of the fixing structure 100, which is more flexible and thus improves the installation efficiency of the fixing structure 100.

[0042] refer to Figures 1 to 3 As shown, an embodiment of this application provides another fixing structure 100 for fixing photovoltaic modules. The fixing structure 100 includes a pressure block 110 and a connecting rod 120.

[0043] The pressing block 110 includes a pressing block body 111, a first connecting member 112, and a second connecting member 113. The pressing block body 111 is connected to the first connecting member 112 and the second connecting member 113 at opposite ends, and the pressing block body 111 is angled to both the first connecting member 112 and the second connecting member 113. The first connecting member 112 and the second connecting member 113 are positioned opposite each other. The first connecting member 112 has a first through hole 1121, and the second connecting member 113 has a second through hole 1131. The connecting rod 120 has a first limiting part 121 and a second limiting part 122 at opposite ends, and the connecting rod 120 can pass through the first through hole 1121 and the second through hole 1131, respectively. When the connecting rod 120 is rotated, the first limiting part 121 engages or disengages with the wall of the first through hole 1121, and the second limiting part 122 engages or disengages with the wall of the second through hole 1131. Correspondingly, the pressure block 110 is applied to the installation of the photovoltaic module. The pressure block 110 is pressed down to the target position of the photovoltaic module, so that the first connecting member 112, the second connecting member 113, and the pressure block body 111 together limit the photovoltaic module. The connecting rod 120 passes through the first through hole 1121 of the first connecting member 112 and the second connecting member 113 respectively. The second through hole 1131 allows the user to rotate the connecting rod 120, which can engage the first locking groove 1212 and the second locking groove 1222 of the connecting rod 120 with the first through hole 1121 and the second through hole 1131 respectively to achieve self-locking. This provides better self-locking stability and pre-tightening force. Alternatively, rotating the connecting rod 120 can separate the first locking groove 1212 and the second locking groove 1222 from the pressure block 110, making it easier to remove the connecting rod 120 after releasing the self-locking. This allows for the installation and disassembly of the fixed structure 100, making the installation and disassembly more flexible and thus improving the installation efficiency of the fixed structure 100.

[0044] For example, the pressing block body 111 is perpendicular to the first connector 112 and the second connector 113 respectively, and the first connector 112 and the second connector 113 are arranged in parallel.

[0045] In one embodiment, alternatively, referencing Figure 3 As shown, the connecting rod 120 is also provided with a third groove 123 and a fourth groove 124. The third groove 123 and the fourth groove 124 are both located between the first limiting part 121 and the second limiting part 122. The third groove 123 and the fourth groove 124 are provided to allow sufficient room for movement. When the connecting rod 120 rotates, the third groove 123 can correspond to the first through hole 1121 and the fourth groove 124 can correspond to the second through hole 1131, which facilitates the rotation of the connecting rod 120 relative to the pressure block 110 and avoids obstruction or jamming.

[0046] Optionally, refer to Figure 1 and Figure 3 As shown, the third groove 123 is located near the first limiting part 121, and the fourth groove 124 is located near the second limiting part 122. The connecting rod 120 can rotate relative to the first connecting member 112 through the third groove 123, and the connecting rod 120 can rotate relative to the second connecting member 113 through the fourth groove 124. Correspondingly, the third groove 123 is near the first limiting part 121, and the fourth groove 124 is near the second limiting part 122. This works in conjunction with the fixing function of the limiting part. The third groove 123 and the fourth groove 124 allow the connecting rod 120 to rotate flexibly relative to the pressure block 110 by reserving space, avoiding jamming or restricted movement due to structural interference. When the connecting rod 120 needs to rotate, the third groove 123 and the fourth groove 124 are aligned with the first through hole 1121 and the second through hole 1131, respectively, providing sufficient clearance for the rotation of the connecting rod 120. When installing or adjusting the component angle, the connecting rod 120 can rotate smoothly without complete disassembly or realignment, thereby improving installation efficiency.

[0047] Furthermore, both the third groove 123 and the fourth groove 124 are annular grooves. The annular groove is a ring-shaped groove that surrounds the circumference of the connecting rod 120. The annular grooves are continuously distributed along the circumference of the connecting rod 120, and the axis of the annular grooves coincides with the axis of the connecting rod 120. The annular grooves provide space for the connecting rod 120 to rotate, so as to facilitate the relative rotation and positioning of the connecting rod 120.

[0048] In one embodiment, alternatively, such as Figure 3 and Figure 4 As shown, the first limiting part 121 includes a first limiting boss 1211, a first engaging groove 1212, and a first stop 1213. The second limiting part 122 includes a second limiting boss 1221, a second engaging groove 1222, and a second stop 1223. The first limiting boss 1211 is located between the first engaging groove 1212 and the third groove 123, and the second limiting boss 1221 is located between the second engaging groove 1222 and the fourth groove 124. Correspondingly, when the connecting rod 120 moves through the first through hole 1121 and the second through hole 1131, the connecting rod 120... The first locking groove 1212 corresponds to the first through hole 1121 and is locked into the hole wall of the first through hole 1121. The first limiting boss 1211 and the first stop block 1213 together limit the hole wall of the first through hole 1121. The second locking groove 1222 of the connecting rod 120 corresponds to the second through hole 1131 and is locked into the hole wall of the second through hole 1131. The second limiting boss 1221 and the second stop block 1223 together limit the hole wall of the second through hole 1131, thereby realizing the self-locking of the connecting rod 120 and the pressure block 110 and ensuring the stability of the fixed structure 100.

[0049] Furthermore, such as Figure 4 As shown, the height of the first stop 1213 is greater than the height of the first limiting boss 1211, and the height of the second stop 1223 is greater than the height of the second limiting boss 1221. Correspondingly, the connecting rod 120 can move relative to the pressure block 110 through the first limiting boss 1211 and the second limiting boss 1221. When the connecting rod 120 moves, the first through hole 1121 of the connecting rod 120 can move relative to the first limiting boss 1211, and the second through hole 1131 can move relative to the second limiting boss 1221. The lower height of the first limiting boss 1211 and the second limiting boss 1221 will not affect or hinder the connecting rod 120, ensuring the flexibility of the structure. When the connecting rod 120 is in the self-locking position, the first stop 1213 and the second stop 1223 are used to limit the movement of the connecting rod 120.

[0050] In this embodiment, the fixing structure 100 has at least a first assembly position and a second assembly position. The first assembly position is a self-locking position, and the second assembly position is a non-self-locking position. When in the first assembly position, the first snap-fit ​​groove 1212 engages with the wall of the first through hole 1121, and the second snap-fit ​​groove 1222 engages with the wall of the second through hole 1131, so that the connecting rod 120 can engage with the pressure block 110. When in the second assembly position, the first through hole 1121 moves to the position of the third groove 123 along the first direction X, and the second through hole 1131 moves to the position of the fourth groove 124, so that the connecting rod 120 can be moved out of the pressure block 110 after rotating at a preset angle. The first direction X is the center line direction of the connecting rod 120. Correspondingly, during the process of switching from the self-locking position to the non-self-locking position, the first locking groove 1212 is separated from the hole wall of the first through hole 1121, and the second locking groove 1222 is separated from the hole wall of the second through hole 1131. The connecting rod 120 is moved so that the first through hole 1121 of the connecting rod 120 corresponds to the third groove 123, and the second through hole 1131 corresponds to the fourth groove 124. Then the connecting rod 120 is rotated to a preset angle so that the cross section of the connecting rod 120 can match the first through hole 1121 or the second through hole 1131, so that the connecting rod 120 can be moved out of the first through hole 1121 or the second through hole 1131.

[0051] For example, the preset angle of the connecting rod 120 is any value between 45° and 135°, such as 45°, 90°, or 135°. The connecting rod 120 has unlocking slots 125 at its opposite ends. The unlocking slots 125 are polygonal in structure, allowing workers to insert tools into them to facilitate rotation of the connecting rod 120 and achieve a labor-saving effect.

[0052] In one embodiment, alternatively, such as Figure 3 and Figure 4 As shown, both the first through hole 1121 and the second through hole 1131 are square holes. The connecting rod 120 has a square structure. Along the first direction X, the adjacent two sides of the cross section of the connecting rod 120 have at least a first side length D1 and a second side length D2, respectively, satisfying: D1 < D2, that is, the lengths of the adjacent two sides of the cross section of the connecting rod 120 are not equal. The cross section of the connecting rod 120 can be rectangular, so that the adjacent two sides of the square structure connecting rod 120 can respectively engage with the first through hole 1121 or the second through hole 1131, or the square structure connecting rod 120 can be moved out through the first through hole 1121 or the second through hole 1131.

[0053] Optionally, refer to Figure 1 As shown, the pressure block 110 is provided with a first positioning plate 114 and a second positioning plate 115. Along the first direction X, the first positioning plate 114 and the second positioning plate 115 connect opposite sides of the pressure block body 111. The first positioning plate 114 and the second positioning plate 115 respectively form a bent structure towards the connecting rod 120. Further, the first positioning plate 114 and the second positioning plate 115 have a certain degree of elasticity. The first positioning plate 114 and the second positioning plate 115 are used to abut against the photovoltaic module and to abut and limit the photovoltaic module. For example, rubber pads are provided on the sides of both the first positioning plate 114 and the second positioning plate 115. The rubber pads can compensate for installation tolerances and reduce metal-to-metal contact noise, and the rubber pads provide protection for the photovoltaic module.

[0054] In one embodiment, optionally, the surface of the fixing structure 100 is provided with a coating layer, the coating layer including an outer fluorocarbon resin surface layer and an inner micro-arc oxidation layer. The inner micro-arc oxidation layer provides sufficient thickness to form a uniform and dense oxide film, enhancing the wear resistance and corrosion resistance of the substrate (such as aluminum alloy). The thickness of the micro-arc oxidation layer can be 50 μm. A 50 μm micro-arc oxidation layer significantly improves the load-bearing capacity and is suitable for the wear resistance requirements of photovoltaic brackets exposed to harsh environments such as wind, sand, and salt spray for a long time. The outer fluorocarbon resin surface layer can still maintain its color and gloss under conditions such as ultraviolet light and humidity, avoiding the decline in optical performance caused by fading of the photovoltaic module surface. It can resist the corrosion of pollutants such as acid rain and ozone, and is especially suitable for industrial exhaust gas or coastal high salt spray environments. Fluorocarbon resin can reduce dust adhesion and reduce the need for cleaning and maintenance of the module surface. The thickness of the outer fluorocarbon resin surface layer can be 30 μm. A 30 μm fluorocarbon resin surface layer can provide a longer weather protection cycle, especially in outdoor environments with strong sunlight.

[0055] An embodiment of this utility model also provides a photovoltaic module, which includes the fixed structure 100 in the above embodiment.
