[0028] Hereinafter, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. It should be noted that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0029] An embodiment of the present application provides a photovoltaic module installation fixture for fixing the photovoltaic module and fixing the photovoltaic module to the purlin of a photovoltaic mounting bracket, so that the photovoltaic module can be fixedly installed in an outdoor application scenario. Figure 1 A schematic diagram of the structure of the installation fixture provided in the embodiment of the present application is shown as follows: Figure 1 As shown, the installation fixture includes a clamping member 100 and a pressing member 200 . Figure 2 A schematic structural diagram of a clamping member 100 provided in an embodiment of the present application is shown. Figure 3 A schematic structural diagram of the holding member 200 provided in an embodiment of the present application is shown.

[0030] like Figures 2 to 3 As shown, the clamp 100 is used to clamp and fix the photovoltaic module. The photovoltaic module usually includes an aluminum frame surrounding it on all sides. The clamp 100 clamps the aluminum frame to facilitate the fixed installation of the photovoltaic module. The clamp 100 includes a first fixing block 110, an intermediate plate 120, and a second fixing block 130 fixedly connected in sequence. The intermediate plate 120 has a bent portion 121 bent toward the second fixing block 130. A slot 131 is formed between the bent portion 121 and the second fixing block 130. The slot 131 is used to clamp the photovoltaic module. A ridge is provided in the slot 131 so that the ridge cooperates with the groove on the aluminum frame. The photovoltaic module can be inserted from the side of the slot 131 and pushed in along the ridge so that the photovoltaic module is firmly clamped in the slot 131. Furthermore, the outer edge of the bent portion 121 can be bent toward the second fixing block 130 to tighten the opening of the slot 131 , so that the outer edge of the bent portion 121 can abut against the aluminum frame of the photovoltaic module to securely clamp the photovoltaic module.

[0031] The upper side 102 of the first fixing block 110 is inclined downward toward the middle plate 120, forming a first inclined groove 101 with the middle plate 120. The first fixing block 110 can be used to secure the clamping member 100 to the purlin 400 of the mounting bracket. The clamping member 100 can be secured by pressing from above the first fixing block 110.

[0032] In the embodiment of the present application, the upper side surface 102 of the first fixing block 110 is tilted downward toward the middle plate 120 , and the height of the middle plate 120 is higher than the height of the first fixing block 110 , so that a first inclined groove 101 is formed between the upper side surface 102 of the first fixing block 110 and the middle plate 120 .

[0033] The holding member 200 is used to hold the first fixing block 110 from its upper side 102, allowing the clamping member 100 to be fixed to the purlin 400 of the mounting bracket. The holding member 200 includes a base plate, a first protrusion 210 disposed in the middle of the base plate, and two lugs 220 disposed on either side of the first protrusion 210. The base plate forms the holding body of the holding member 200, connecting the first protrusion 210 and the two lugs 220. The first protrusion 210 and the two lugs 220 are used to achieve the functions of limiting and holding. The middle portion of the base plate can be part of the first protrusion 210, and the two sides can also be parts of the lugs 220. In other words, the base plate can be the connecting area between the first protrusion 210 and the two lugs 220, and does not necessarily have a plate-shaped structure. The base plate, first protrusion 210, and lugs 220 are a one-piece structure, forming a roughly T-shape after integral molding. The hook 220 is hooked onto the first fixing block 110 of the two opposing clamping members 100, and by pressing the first protrusion 210, the two clamping members 100 are pressed and fixed. The lower side 221 of the hook 220 is inclined toward the base plate, toward the first protrusion 210, and forms a second inclined groove 201 with the first protrusion 210. The second inclined groove 201 is adapted to fit the first inclined groove 101, so that when the hook 220 is hooked onto the first fixing block 110, the first inclined groove 101 and the second inclined groove 201 are aligned.

[0034] like Figures 1 to 5 As shown, in this embodiment of the present application, the first and second inclined grooves 101 and 201 are aligned to form at least two contact surfaces. When the photovoltaic module is subjected to upward or downward wind forces, the photovoltaic module drives the clamping member 100 to exert an upward or downward tilting force. On the first contact surface 501, due to its inclined surface, the hanging ear 220 exerts an oblique force on the first fixing block 110, which can be used to resist this rotational force, thereby enhancing wind resistance.

[0035] In one example, the photovoltaic module is subjected to an upward wind force or an upward and left-slanting wind force. Figure 4 The photovoltaic module on the right side of the center panel tends to rotate upward and counterclockwise to the left. The force of the second contact surface 502 resists the leftward rotation of the middle panel 120. At the same time, the first contact surface 501 exerts a downward force that tilts leftward, resisting the upward force. Compared to a flush arrangement of the upper side 102, this tilted arrangement more effectively counteracts the force of wind, thus providing greater wind resistance.

[0036] In one example, the photovoltaic assembly is subjected to downward wind force, and the clamping member 100 on the right side of the figure has a tendency to rotate clockwise to the right. The first contact surface 501 has a downward and leftward resistance force to resist the rightward rotation of the first fixing block 110.

[0037] The cooperation between the first bevel groove 101 and the second bevel groove 201 can also limit the distance between the two relative clamping members 100 to ensure that the side of the ear 220 fits with the middle plate 120, thereby generating an interaction force on the second contact surface 502; further, it can also ensure that the first protrusion 210 fits with the first fixing block 110, so that an interaction force is generated on the third contact surface 503.

[0038] The embodiment of the present application provides better mechanical properties for resisting strong winds and improves wind resistance through the cooperation of the first inclined groove 101 and the second inclined groove 201.

[0039] In one embodiment, the angle of the first chute 101 is 15° to 75°, and the depth of the first chute 101 is 3-10 cm.

[0040] The angle of the first chute 101 can be understood as the angle formed by the upper side 102 of the first fixing block 110 and the middle plate 120. The upper side 102 of the first fixing block 110 needs to have a certain inclination to provide a force in the inclined direction to resist strong winds. The middle plate 120 can be arranged vertically, and vertical arrangement here can be understood as being arranged perpendicular to the purlin 400. Therefore, the first chute 101 is formed between the inclined upper side 102 of the first fixing block 110 and the middle plate 120. The angle of the first chute 101 depends on the angle at which the first fixing block 110 is inclined.

[0041] The angle of the first inclined groove 101 can be set according to the climate environment of the photovoltaic module installation site. In areas with strong winds, a smaller inclination angle can be set, that is, the upper side surface 102 of the first fixing block 110 is set closer to the middle plate 120; in areas with weak winds, a larger inclination angle can be set.

[0042] The angle of the first inclined slot 101 cannot be too small. If it is too small, the width of the hanging ear 220 will be too thin, which will affect the pressing effect of the pressing member 200 and cause the downward pressure to be insufficient to resist strong winds.

[0043] If the angle of the first inclined slot 101 is too large, the resistance in the inclined direction will be insufficient, making it difficult to achieve the effect of resisting strong winds.

[0044] Therefore, the embodiment of the present application limits the angle of the first chute 101 to 15° to 75°, for example, 15°, 30°, 50°, 60°, or 75°. Preferably, the angle of the first chute 101 can be limited to 30° to 70° to ensure the photovoltaic module's resistance to strong winds.

[0045] Similarly, if the first chute 101 is too deep, the hook 220 will need to be deeper to fit within the first chute 101, which will result in the hook 220 being wider, causing the two opposing clamping members 100 to be farther apart and wasting space on the purlin 400. If the first chute 101 is too shallow, the hook 220 will have insufficient resistance to tilting, making it difficult to resist strong winds.

[0046] Therefore, the embodiment of the present application limits the angle of the first inclined groove 101 to 3-10 cm, for example, 3 cm, 4 cm, 6 cm, and 10 cm are all feasible.

[0047] In one embodiment, the lower edge of the upper side 102 of the first fixing block 110 is lower than the height of the second fixing block 130 , and the upper edge of the upper side 102 of the first fixing block 110 is higher than the height of the second fixing block 130 .

[0048] The upper side surface 102 of the first fixing block 110 is tilted, so the two edges of the upper side surface 102 of the first fixing block 110 have different heights, the higher edge being the higher edge and the lower edge being the lower edge.

[0049] It can be known that when the photovoltaic component rotates, the second fixed block 130 is used as a fulcrum. In the embodiment of the present application, by having the high edge higher than the height of the second fixed block 130 and the low edge lower than the height of the second fixed block 130, the force at the center position of the first contact surface 501 can be directed against the rotational force of the photovoltaic component to enhance the resistance effect. The force of the second contact surface 502 can also act on the second fixed block 130 and the photovoltaic component at the same time, further enhancing the resistance effect.

[0050] In one embodiment, the height of the first protrusion 210 protruding from the hanging ear 220 is 1 / 4 to 1 / 2 of the height of the first fixing block 110 .

[0051] The height of the first protrusion 210 protruding from the hanging ear 220 may be a height protruding from the lower edge of the hanging ear 220 .

[0052] The first protrusion 210 needs to protrude beyond the lug 220 so that the first protrusion 210 is clamped between the two opposing clamping members 100 and generates a horizontal resistance force against the two clamping members 100. If the first protrusion 210 protrudes too low from the lug 220, it will be difficult to generate sufficient horizontal resistance force.

[0053] The first protrusion 210 may extend to abut against or be close to the purlin 400 , but such a structure consumes more material costs and is inconvenient for pressing the first fixing block 110 .

[0054] The height of the first protrusion 210 protruding from the hanging ear 220 is 1 / 4 to 1 / 2 of the height of the first fixing block 110 , for example, 1 / 4, 1 / 3 or 1 / 2.

[0055] In one embodiment, when the hanging ear 220 is hung on the first fixing block 110 , the height of the bottom plate is higher than or flush with the height of the bent portion 121 .

[0056] In the embodiment of the present application, the bottom plate of the pressing member 200 is pressed on the first fixing block 110 rather than the bent portion 121 , which can avoid damage to the photovoltaic module when a large pressing force is applied.

[0057] The height of the bottom plate is higher than or flush with the height of the bent portion 121, which can ensure the abutment between the hanging ear 220 and the middle plate 120, so that the position of the second contact surface 502 generates a mutual force, and the area of ​​action of the force is large, providing stronger wind resistance.

[0058] In one embodiment, it also includes a locking bolt 300, the holding member 200 is provided with a first bolt hole 202 that passes through the base plate and the first protrusion 210, the clamping member 100 is arranged on the purlin 400 of the photovoltaic bracket, and the purlin 400 is provided with a second bolt hole; the two hanging ears 220 in the holding member 200 are respectively hung on the two relatively arranged clamping members 100, and the locking bolt 300 passes through the first bolt hole 202 and the second bolt hole and is locked.

[0059] In the embodiment of the present application, the pressing member 200 and the purlin 400 are pressed and fixed by the locking bolt 300 , thereby fixing the clamping member 100 on the purlin 400 .

[0060] In the embodiment of this application, Figure 3 As shown, the clamping member 100 is a long plate rib to completely clamp the entire frame of the photovoltaic module and stabilize the photovoltaic module. The first fixing block 110, the middle plate 120 and the second fixing block 130 in the clamping member 100 can be integrally formed.

[0061] In the pressing member 200, the bottom plate, the first protrusion and the hanging ear 220 can be integrally formed, wherein the hanging ear 220 and the first protrusion can be designed with a hollow structure, for example Figure 3 The hollow structure shown can reduce the mass of the pressing member 200 while providing resistance, thereby reducing material costs.

[0062] The length of the pressing member 200 can be shorter than that of the clamping member 100. Two to six pressing members 200 can be configured on one clamping member 100. That is, the clamping member 100 is fixed to the purlin 400 via two to six bolts 300. The two to six pressing members 200 are evenly distributed on the clamping member 100. For example, if there are two pressing members 200, they can be respectively arranged at the head end and the tail end of the clamping member 100.

[0063] In one embodiment, the first fixing block 110 or the second fixing block 130 is a plate reinforcement block with a hollow structure.

[0064] In the first fixing block 110, the pressing member 200 presses against the upper side 102 of the first fixing block 110, thereby achieving the effect of pressing the clamping member 100. Therefore, the first fixing block 110 only needs to have a stable or firm upper side 102, and the rest of the structure is not limited. By adopting a hollow structure for the first fixing block 110, the structure of the first fixing block 110 can be stabilized, the upper side 102 can have a certain height, or the height of the upper side 102 can be set as required, and the material consumption can be reduced, thereby reducing the weight of the clamping member 100.

[0065] Similarly, in the second fixing block 130, the upper side of the second fixing block 130 and the bent portion 121 form a slot 131 to hold the photovoltaic module. Therefore, the second fixing block 130 only needs to have a stable or firm upper side, and the remaining structure is not limited. By adopting a hollow structure for the second fixing block 130, the structure of the second fixing block 130 can be stabilized, the upper side of the second fixing block 130 can have a certain height, or the height of the upper side of the second fixing block 130 can be set as required, and the material consumption can be reduced, reducing the weight of the clamp 100.

[0066] In an embodiment of the present application, in order to further enhance the application of photovoltaic modules in extreme environments, a reinforcing layer can be added inside the photovoltaic module. The reinforcing layer is arranged in the adhesive film between the back panel glass and the battery cell. The reinforcing layer separates the adhesive film into two layers of adhesive film, and the two layers of adhesive film are located on opposite sides of the reinforcing layer.

[0067] The reinforcement layer may be a TPU (Thermoplastic polyurethanes) film or a PVB (PolyVinylButyral Film) film.

[0068] The present application also provides a photovoltaic module mounting bracket, comprising a purlin 400 and a mounting fixture according to any of the above embodiments. The purlin 400 and the mounting fixture cooperate as described above.

[0069] In one embodiment, the purlin 400 is provided with a second bolt hole, and a second protrusion 410 is provided on a side of the purlin 400 facing away from the installation fixture, and the second bolt hole passes through the second protrusion 410 .

[0070] In the embodiment of the present application, a second protrusion 410 is provided on the purlin 400. When the nut is tightened, it can be locked with a greater force so that the nut is tightly screwed on the second protrusion 410. The second protrusion 410 can withstand greater pressure, thereby making the holding member 200 and the purlin 400 firmly locked, further improving the ability to resist strong winds.

[0071] In one embodiment, the clamping member 100 in the installation fixture is fixed to the purlin 400 via threads, and the fixing bolts pass through the hollow position of the first fixing block 110 or the second fixing block 130 to the purlin 400 .

[0072] Based on the hollow setting of the first fixing block 110 or the second fixing block 130, a fixing bolt can be screwed into the edge of the clamp 100, and the fixing bolt passes through the bottom of the first fixing block 110 or the second fixing block 130 and the purlin 400, and is tightened and fixed by a nut from the direction of the purlin 400 away from the clamp 100, thereby further enhancing the stability of the clamp 100 and improving the strong wind resistance of the photovoltaic module.

[0073] An embodiment of the present application further provides a photovoltaic system, comprising: a plurality of photovoltaic modules, wherein the plurality of photovoltaic modules are mounted on a mounting bracket according to any one of the above embodiments.
