[0001] This application claims priority to Chinese Patent Application No. 202411187338.2, filed on August 28, 2024, entitled “Pressed Module, Module Frame, Photovoltaic Module and Photovoltaic System”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of photovoltaic technology, specifically providing a compacted module, a module frame, a photovoltaic module, and a photovoltaic system. Background Technology

[0003] A photovoltaic (PV) module is a device that can directly convert light energy into electrical energy using the photovoltaic effect. A PV module typically includes a module frame and laminates. During the installation of a PV module, the module frame is fixed to a PV support structure.

[0004] Flexible photovoltaic (PV) mounting systems are highly adaptable, allowing for adjustments and installations to suit various environments and meet diverse site requirements. PV modules are typically mounted on these systems using clamping assemblies to secure them to tensioned steel strands.

[0005] However, existing bridging modules on the market can only fix the bottom plate of the photovoltaic module frame, but have no restrictions on the top plate of the frame. When the photovoltaic module is in windy weather, the bottom plate of the photovoltaic module frame is easily torn due to the large force, causing the photovoltaic module to fall off, resulting in poor installation stability of the photovoltaic module. Summary of the Invention

[0007] In a first aspect, the present invention provides a clamping assembly for fixing a photovoltaic module to a flexible support. The module frame has a top frame plate, a bottom frame plate, and a side frame plate. The top frame plate has a plurality of first toothed structures arranged sequentially along a first direction. The clamping assembly includes: a first clamping block disposed opposite to the top frame plate, with a plurality of second toothed structures arranged sequentially along the first direction on the side of the first clamping block near the top frame plate; a second clamping block disposed opposite to and fixedly connected to the bottom frame plate, the second clamping block being able to be fixed to the flexible support; and a connecting member disposed opposite to the side frame plate, the two ends of the connecting member being connected to the first clamping block and the second clamping block, respectively.

[0009] In the preferred embodiment of the above-mentioned pressing block assembly, the depth of the groove gradually increases along the first direction from the end near the side plate of the frame to the end away from the side plate of the frame.

[0010] In the preferred embodiment of the above-mentioned pressing block assembly, the groove has a first sidewall and a second sidewall, the distance between the first sidewall and the connecting member in the first direction is greater than the distance between the second sidewall and the connecting member in the first direction, the first tooth structure has a first tooth surface and a second tooth surface, the distance between the first tooth surface and the frame side plate in the first direction is greater than the distance between the second tooth surface and the frame side plate in the first direction, wherein the first distance between the first tooth surface and the first sidewall in the first direction is less than the second distance between the second tooth surface and the second sidewall in the first direction.

[0013] In the preferred embodiment of the above-mentioned pressing block assembly, the frame top plate has a first region and a second region distributed sequentially along the first direction, wherein the thickness of the frame top plate in the first region in the second direction is greater than the thickness of the frame top plate in the second region in the second direction, and the gap between the tip of the first tooth structure in the first region and the inner wall of the groove in the second direction is smaller than the gap between the tip of the first tooth structure in the second region and the inner wall of the groove in the second direction.

[0015] In the preferred embodiment of the above-mentioned pressing block assembly, the width of the end of the first toothed structure near the top plate of the frame is 0.8mm-3mm; and / or, the width of the tip of the first toothed structure is 0.15mm-0.5mm; and / or, the tip of the first toothed structure is an arc-shaped surface with a radius of 0.1mm-1mm; and / or, the tip of the first toothed structure is a plane.

[0016] In the preferred embodiment of the above-mentioned compacted assembly, the photovoltaic module further includes a laminate, and the top plate of the frame has a contact portion on the side away from the first toothed structure, wherein the first toothed structure on the side away from the frame side plate is located above the contact portion and the line connecting the vertex of the first toothed structure and the midpoint of the contact portion is perpendicular to the laminate.

[0017] In a preferred embodiment of the above-described pressing block assembly, the connecting member has a first extension arm extending along the first direction and a second extension arm extending along the second direction; or, the connecting member has a first extension arm extending along the first direction and a second extension arm extending along the second direction, and the pressing block assembly further includes a fixing member for fixing the first extension arm to the second pressing block; or, the connecting member only has a second extension arm extending along the second direction; wherein, the second extension arm is connected to the first pressing block, and the second extension arm is disposed opposite to the side panel of the frame.

[0018] In the preferred embodiment of the above-mentioned pressing block assembly, the connecting member extends from the second pressing block to the first pressing block, and the cross-sectional thickness of the connecting member gradually decreases along its extending direction.

[0019] In the preferred embodiment of the above-mentioned pressure block assembly, the pressure block assembly further includes a third pressure block and a locking member. The locking member is used to lock the second pressure block and the third pressure block. When installed, the flexible bracket is clamped between the second pressure block and the third pressure block.

[0020] In the preferred embodiment of the above-mentioned pressure block assembly, the locking member is a locking bolt and a locking nut, the second pressure block and the third pressure block are provided with locking holes adapted to the locking bolt, the locking bolt passes through the locking hole and is connected to the locking nut; and / or, the second pressure block and / or the third pressure block are provided with a limiting structure adapted to the flexible bracket, and when installed, a portion of the flexible bracket is located within the limiting structure.

[0021] In the preferred embodiment of the above-mentioned pressing block assembly, the pressing block assembly further includes a hinge member, through which the second pressing block and the third pressing block are hingedly connected.

[0022] In a second aspect, the present invention provides a component frame having a top frame, a bottom frame, and side frames. The top frame is provided with a plurality of first tooth-shaped structures arranged sequentially along a first direction. The component frame is combined with the pressing block component described in the first aspect and fixes the photovoltaic module on the flexible support.

[0023] In a third aspect, the present invention provides a photovoltaic module, the photovoltaic module comprising a laminate and the module frame described in the second aspect.

[0024] In a fourth aspect, the present invention also provides a photovoltaic system, the photovoltaic system comprising the bridging assembly described in the first aspect, the photovoltaic module described in the third aspect, and a flexible support, the flexible support being used to support the photovoltaic module.

[0025] In the preferred technical solution of the above-mentioned pressure block assembly, by setting a first pressure block at a position corresponding to the top plate of the frame and a second pressure block at a position corresponding to the bottom plate of the frame, it is possible to prevent the bottom plate of the frame from tearing under strong wind loads and to prevent the photovoltaic module from falling off. At the same time, through the cooperation of the first tooth structure and the second tooth structure, it is possible not only to prevent the photovoltaic module from swaying left and right, but also to prevent the laminate from being compressed due to excessive deformation of the edge of the module frame under heavy snow loads, thereby effectively preventing the glass of the laminate from being crushed.

[0026] Furthermore, by creating a gap between the tip of the first tooth structure and the sidewall of the groove in the second direction, and by gradually increasing the gap along the first direction from the end near the side plate to the end away from the side plate, when the first pressing block is pressed against the top plate of the frame, on the one hand, the pressing force between the end of the first pressing block near the side plate and the top plate of the frame is larger, and the pressing force between the end of the first pressing block away from the side plate and the top plate of the frame is smaller. This allows the pressing force applied by the first pressing block to the frame of the module to be transmitted from the side plate as much as possible, thus more effectively preventing the glass from being crushed. On the other hand, when the photovoltaic module is under a heavy snow positive pressure load, it can prevent the glass from being crushed due to excessive deformation of the edge of the module frame under heavy snow load.

[0027] Furthermore, by setting the depth of the groove to gradually increase from the end near the side plate to the end away from the side plate along the first direction, the cross-sectional thickness of the first pressure block gradually decreases from the end near the side plate to the end away from the side plate along the first direction. This makes the first pressure block elastic. On the one hand, it facilitates the insertion of the photovoltaic module between the first and second pressure blocks, improving installation efficiency. On the other hand, it can balance the vibration amplitude at different positions on the photovoltaic module, improving the installation stability of the photovoltaic module. At the same time, in extreme snowy weather, the elasticity of the first pressure block can also cause the first toothed structure at the end away from the side plate to disengage from the corresponding second toothed structure, preventing the glass from being crushed due to excessive deformation of the module frame.

[0028] Furthermore, by setting the distance between the first tooth surface and the first sidewall to be smaller than the distance between the second tooth surface and the second sidewall, on the one hand, it can effectively resist the clockwise rotation of the photovoltaic module under the positive pressure load of heavy snow, and on the other hand, it can effectively resist the counterclockwise rotation of the photovoltaic module under the negative pressure load of strong wind, thus improving the installation stability of the photovoltaic module. On the other hand, when the first tooth structure contacts the second tooth structure, the horizontal component of the clamping force applied by the first pressing block to the top plate of the frame can be used to resist the rotation of the photovoltaic module, and the vertical component of the clamping force can be applied to the laminate, thus avoiding excessive clamping force applied to the laminate and crushing the glass.

[0029] Furthermore, by controlling the included angle α between a and b within the range of 5°-20°, the first distance between the first tooth surface and the first sidewall in the first direction and the second distance between the second tooth surface and the second sidewall in the first direction can both be controlled within a better range. This avoids the problem of poor contact stability caused by the small contact area between the first tooth surface and the first sidewall when the first tooth structure and the second tooth structure come into contact due to the included angle between a and b being too large.

[0030] Furthermore, setting the angle β between the second tooth surface and the vertical direction to 10°-30° has several advantages. First, when the photovoltaic module is under a positive pressure load from heavy snow, the contact area between the first tooth structure (first tooth surface) and the second tooth structure is larger when the first tooth structure contacts the second tooth structure. This helps to improve the contact stability between the first and second tooth structures and prevents the first tooth structure from detaching from the second tooth structure. Second, it also facilitates the better fit between the first and second tooth structures and prevents the module frame from being unable to rotate due to an excessively small angle.

[0031] Furthermore, by setting the angle γ1 between the first sidewall and the second direction to less than 45°, when the photovoltaic module is under a positive pressure load from heavy snow, when the first toothed structure comes into contact with the second toothed structure, a larger component of the clamping force can be used to resist the clockwise rotation of the photovoltaic module, while a smaller component is applied to the laminate. This effectively resists the rotation of the photovoltaic module and prevents the module frame from pressing on the glass and causing it to shatter. By setting the angle γ2 between the second sidewall and the second direction to less than 45°, when the photovoltaic module is under a negative pressure load from strong winds, when the first toothed structure comes into contact with the second toothed structure, a larger component of the clamping force can be used to resist the counterclockwise rotation of the photovoltaic module, while a smaller component is applied to the laminate. This effectively resists the rotation of the photovoltaic module and prevents the module frame from pressing on the glass and causing it to shatter.

[0032] Furthermore, by making the gap H1 in the first region smaller than the gap H2 in the second region, on the one hand, the first toothed structure in the first region can preferentially contact the second toothed structure, and the first toothed structure in the second region can subsequently contact (or not contact) the second toothed structure. This concentrates the clamping force applied by the first pressing block to the frame assembly more in the first region, more effectively preventing the clamping force applied by the first pressing block from crushing the glass. At the same time, since the thickness of the frame top plate in the first region is greater than its thickness in the second region, the force applied by the first pressing block to the frame top plate can be mainly concentrated in the region with greater thickness of the frame top plate, effectively resisting deformation of the frame top plate. On the other hand, when the photovoltaic module is under extreme snow pressure load, the first toothed structure in the second region can preferentially detach from the second toothed structure, and the first toothed structure in the first region can detach from the second toothed structure later. This provides maintenance personnel with some time for emergency repairs and prevents all the first toothed structures from detaching from the second toothed structure at the same time, which would cause the photovoltaic module to fall off, further improving the installation stability of the photovoltaic module.

[0033] Furthermore, by configuring the connecting member to include a first extension arm extending along a first direction and a second extension arm extending along a second direction, and / or by gradually decreasing the cross-sectional thickness of the connecting member along its extension direction, the first pressure block can have a certain degree of elasticity. On the one hand, during installation, the elasticity of the first pressure block facilitates the insertion of the module frame between the first and second pressure blocks, reducing installation difficulty and improving installation efficiency. On the other hand, the elasticity of the first pressure block can also balance the deviation of vibration amplitude at different positions of the photovoltaic module, improving installation stability. At the same time, the elasticity of the first pressure block can also help the first toothed structure at the end away from the side plate of the frame to disengage from the corresponding second toothed structure when the module frame is subjected to large forces under heavy snow positive pressure loads, thus preventing excessive force from causing the glass to shatter.

[0034] Furthermore, by setting a fixing component, when the photovoltaic module is installed in an area with high wind speed, the first extension arm can be fixed to the second pressure block, thereby reducing the elasticity of the first pressure block, reducing the vibration amplitude of the photovoltaic module, and pressing the first pressure block tightly against the top of the module frame, assisting the frame base plate in bearing the load, avoiding excessive force on the frame base plate and causing tearing, and thus facilitating flexible adjustment of the elasticity of the first pressure block according to the actual installation situation.

[0035] Furthermore, by setting the second and third pressure blocks to be connected by hinges, on the one hand, the overall integrity of the pressure block assembly can be improved, which not only saves on-site assembly time but also facilitates the transportation of the pressure block assembly, thus improving the convenience of installation and transportation; on the other hand, during the installation of photovoltaic modules, there is no need for workers to align the holes on-site, and the pressure block assembly can be pre-installed on the photovoltaic modules and then locked by locking components, which greatly improves the installation efficiency of photovoltaic modules.

[0036] Furthermore, the photovoltaic system further provided by the present invention, based on the above technical solution, includes the aforementioned bridging component, and thus possesses the beneficial effects of the aforementioned bridging component. Compared with the photovoltaic system before the improvement, the photovoltaic system of the present invention is more resistant to strong winds and heavy snow loads, the photovoltaic components are less likely to fall off, and the installation stability is higher.

Detailed Implementation

[0058] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0059] It should be noted that in the description of this invention, terms such as "upper," "lower," "left," "right," "inner," "top," and "bottom," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0060] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly, for example, referring to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0061] As shown in Figures 1 to 10, the photovoltaic module 1 of the present invention includes a module frame and a laminate 14. The module frame is disposed on the edge of the laminate 14. The module frame has a top plate 11, a bottom plate 12, and a side plate 13. The top plate 11 is provided with a plurality of first tooth-shaped structures 111 arranged sequentially along a first direction.

[0062] As shown in Figures 1 to 10, the clamping block assembly 2 is used to fix the photovoltaic module 1 on the flexible support 3. The clamping block assembly 2 includes a first clamping block 21, a second clamping block 22, and a connecting member 24. The first clamping block 21 is disposed opposite to the top plate 11 of the frame. The side of the first clamping block 21 near the top plate 11 of the frame has a plurality of second tooth-shaped structures 211 arranged sequentially along a first direction. The second clamping block 22 is disposed opposite to the bottom plate 12 of the frame and can be fixedly connected to the bottom plate 12 of the frame. The second clamping block 22 can be fixed on the flexible support 3. The connecting member 24 is disposed opposite to the side plate 13 of the frame, and the two ends of the connecting member 24 are respectively connected to the first clamping block 21 and the second clamping block 22.

[0063] When installed, the first toothed structure 111 and the second toothed structure 211 cooperate to prevent the component frame from moving relative to the first pressure block 21 in a first direction and to allow the component frame to move relative to the first pressure block 21 in a second direction, wherein the first direction is perpendicular to the second direction.

[0064] It should be noted that, as shown in Figures 3, 4, 6, 8 and 10, the first direction is the horizontal direction and the second direction is the vertical direction.

[0065] With this configuration, on the one hand, by setting the first pressure block 21 and the second pressure block 22 opposite to the top plate 11 and bottom plate 12 of the module frame respectively, the vibration amplitude of the top plate 11 can be reduced, thereby preventing the bottom plate 12 from tearing in strong winds, thus preventing the photovoltaic module 1 from falling off, and avoiding the installation complexity caused by using multiple pressure blocks. On the other hand, the cooperation of the first toothed structure 111 and the second toothed structure 211 not only prevents the module frame from moving relative to the first pressure block 21 in the first direction, thus preventing the photovoltaic module 1 from swaying left and right, but also allows the module frame to move relative to the first pressure block 21 in the second direction, so as to avoid the laminate 14 being crushed due to excessive deformation of the edge of the module frame under heavy snow load, thus preventing the glass of the laminate 14 from being crushed. In addition, the setting of the first toothed structure 111 and the second toothed structure 211 can also help to pre-install the pressure block assembly 2 onto the photovoltaic module 1, preventing the pressure block assembly 2 from falling off the photovoltaic module 1.

[0066] It should be noted that, in practical applications, those skilled in the art can arrange the first toothed structure 111 and the second toothed structure 211 to be alternately distributed along the first direction, that is, two adjacent second toothed structures 211 form a groove 212, and when installed, the first toothed structure 111 is located in the groove 212. Alternatively, the number of the first toothed structure 111 can be set to be greater than the number of the second toothed structure 211, that is, two adjacent second toothed structures 211 form a groove 212, and when installed, at least a portion of the first toothed structure 111 is located in the groove 212. Furthermore, the number of the second toothed structure 211 can be set to be greater than the number of the first toothed structure 111, that is, two adjacent second toothed structures 211 form a groove 212, and the first toothed structure 111 is located in a portion of the groove 212, and so on. Such adjustments and changes to the specific distribution of the first toothed structure 111 and the second toothed structure 211 do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0067] Preferably, as shown in Figures 3 and 10, a groove 212 is formed between two adjacent second toothed structures 211. When installed, the first toothed structure 111 is located in the groove 212. At least a portion of the tip of the first toothed structure 111 has a gap 112 with the inner wall of the groove 212 in the second direction, and the gap 112 gradually increases along the first direction from one end near the side plate 13 to one end away from the side plate 13.

[0068] By gradually increasing the gap 112 along the first direction from the end near the side plate 13 to the end away from the side plate 13, when the first pressing block 21 is pressed against the top plate 11 of the frame, on the one hand, the pressing force between the end of the first pressing block 21 near the side plate 13 and the top plate 11 of the frame is larger, and the pressing force between the end of the first pressing block 21 away from the side plate 13 and the top plate 11 of the frame is smaller. This allows the pressing force applied by the first pressing block 21 to the frame of the module to be transmitted as much as possible from the position of the side plate 13, thus more effectively preventing the glass from being crushed. On the other hand, when the photovoltaic module 1 is under a heavy snow positive pressure load, it can prevent the glass from being crushed due to excessive deformation of the edge of the module frame under heavy snow load.

[0069] It should be noted that the gap 112 here refers to the distance between the tip of the first tooth structure 111 and the inner wall of the groove 212 in the second direction.

[0070] For example, as shown in Figures 3 and 10, the gap 112 between the first toothed structure 111 and the inner wall of its corresponding groove 212 in the second direction is H.

[0071] It should be noted that in practical applications, only some of the tips of the first tooth-shaped structure 111 and the inner wall of the groove 212 have a gap 112 in the second direction, or all the tips of the first tooth-shaped structure 111 and the inner wall of the groove 212 have a gap 112 in the second direction, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0072] In one specific embodiment, as shown in FIG3, all the first toothed structures 111 and the inner wall of the groove 212 have a gap 112 in the second direction.

[0073] When the photovoltaic module 1 is installed under normal weather conditions, the bottom plate 12 of the frame of the photovoltaic module 1 is fixedly connected to the second pressure block 22. That is, only the bottom plate 12 of the frame bears the load at this time. The first pressure block 21 does not apply pressure to the top plate 11 of the frame. There is a gap 112 between the top plate 11 of the frame and the first pressure block 21, which can ensure that the photovoltaic module 1 has a certain buffer space when vibrating. When the vibration amplitude is small, the top plate 11 of the frame will not contact the first pressure block 21. When the vibration amplitude is large, the top plate 11 of the frame will contact the first pressure block 21 during the vibration. Under the action of the first pressure block 21, the vibration amplitude of the photovoltaic module 1 is reduced.

[0074] In another specific embodiment, as shown in FIG10, only the tip of the first toothed structure 111 away from the side plate 13 has a gap 112 with the inner wall of the groove 212 in the second direction. The gap 112 gradually increases along the first direction from the end near the side plate 13 to the end away from the side plate 13.

[0075] With this arrangement, the tip of the first toothed structure 111 near the side plate 13 abuts against the inner wall of the groove 212, while only the tip of the first toothed structure 111 away from the side plate 13 has a gap 112 with the inner wall of the groove 212 in the second direction. On the one hand, when the photovoltaic module 1 is installed under conditions of high wind load, the side of the top plate 11 near the side plate 13 can contact the first pressure block 21, and the first pressure block 21 applies a pressing force to the top plate 11, assisting the bottom plate 12 in bearing the high wind load. The first pressure block 21 has a larger clamping force between the end of the first pressure block 21 near the side plate 13 and the top plate 11, and a smaller clamping force between the end of the first pressure block 21 away from the side plate 13 and the top plate 11. This allows the clamping force applied by the first pressure block 21 to the frame to be transmitted as far as possible from the side plate 13, thereby preventing the clamping force of the first pressure block 21 from being transmitted from the laminate 14 to the photovoltaic module 1, and more effectively preventing the glass from being crushed.

[0076] It should be noted that, in practical applications, those skilled in the art can set the depth of the groove 212 to gradually increase along the first direction from the end near the side plate 13 to the end away from the side plate 13, thereby making the gap 112 gradually increase along the first direction from the end near the side plate 13 to the end away from the side plate 13. Alternatively, the height of the first tooth structure 111 can be set to gradually decrease along the first direction from the end near the side plate 13 to the end away from the side plate 13, thereby making the gap 112 gradually increase along the first direction from the end near the side plate 13 to the end away from the side plate 13, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0077] Preferably, the depth of the groove 212 gradually increases along the first direction from one end near the side plate 13 to the end away from the side plate 13.

[0078] With this configuration, the cross-sectional thickness of the first pressure block 21 gradually decreases along the first direction from the end near the frame side plate 13 to the end away from the frame side plate 13, making the first pressure block 21 elastic. On the one hand, this facilitates the insertion of the photovoltaic module 1 between the first pressure block 21 and the second pressure block 22, improving installation efficiency. On the other hand, it balances the vibration amplitude at different positions on the photovoltaic module 1, improving the installation stability of the photovoltaic module 1. At the same time, in extreme snowy weather, the elasticity of the first pressure block 21 also allows the first toothed structure 111 at the end away from the frame side plate 13 to detach from the corresponding second toothed structure 211, preventing the glass from being crushed due to excessive deformation of the module frame.

[0079] Specifically, the depth of the groove 212 ranges from 1mm to 5mm.

[0080] It should be noted that, in practical applications, those skilled in the art can set the distance between the two tooth surfaces of the first tooth structure 111 and the two adjacent second tooth structures 211 to be equal, or the distance between one tooth surface of the first tooth structure 111 and the adjacent second tooth structure 211 can be set to be greater than the distance between the other tooth surface and the adjacent second tooth structure 211, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0081] Preferably, as shown in FIG3, the groove 212 has a first sidewall 2121 and a second sidewall 2122. The distance between the first sidewall 2121 and the connecting member 24 in the first direction is greater than the distance between the second sidewall 2122 and the connecting member 24 in the first direction. The first tooth structure 111 has a first tooth surface 1111 and a second tooth surface 1112. The distance between the first tooth surface 1111 and the frame side plate 13 in the first direction is greater than the distance between the second tooth surface 1112 and the frame side plate 13 in the first direction. When installed, the first distance 2131 between the first tooth surface 1111 and the first sidewall 2121 in the first direction is less than the second distance 2132 between the second tooth surface 1112 and the second sidewall 2122 in the first direction.

[0082] By setting the first distance 2131 between the first tooth surface 1111 and the first sidewall 2121 to be smaller than the second distance 2132 between the second tooth surface 1112 and the second sidewall 2122, on the one hand, when the photovoltaic module 1 is under the positive pressure load of heavy snow, it can effectively resist the clockwise rotation of the photovoltaic module 1, and when the photovoltaic module 1 is under the negative pressure load of strong wind, it can effectively resist the counterclockwise rotation of the photovoltaic module 1, thereby improving the installation stability of the photovoltaic module 1; on the other hand, when the first tooth structure 111 contacts the second tooth structure 211, the horizontal component of the clamping force applied by the first pressing block 21 to the top plate 11 of the frame can be used to resist the rotation of the photovoltaic module 1, and the vertical component of the clamping force can be applied to the laminate 14, thereby preventing the clamping force applied to the laminate 14 from being too large and crushing the glass.

[0083] The following two scenarios will be used to provide a detailed analysis of the stress on photovoltaic modules under the conditions of positive pressure load from heavy snow and negative pressure load from strong winds.

[0084] Scenario 1:

[0085] As shown in Figures 5 and 6, under the condition of a positive pressure load from heavy snow, the photovoltaic module 1 rotates clockwise relative to the first pressure block 21 under the gravity of the snow accumulation on the photovoltaic module 1, thereby causing the top plate 11 of the frame to rotate clockwise. Because the first distance 2131 between the first toothed surface 1111 and the first sidewall 2121 is small, and the second distance 2132 between the second toothed surface 1112 and the second sidewall 2122 in the first direction is large (as shown in Figure 3), the first toothed structure 111 can contact the second toothed structure 211 more quickly (as shown in Figure 6, the first toothed surface 1111 contacts the first sidewall 2121 as quickly as possible). After the first toothed structure 111 contacts the second toothed structure 211, the second toothed structure... The structure 211 applies a force F1 to the first toothed structure 111. The force F1 can be decomposed into a horizontal component F1x and a vertical component F1y. F1x is opposite in direction to the force that causes the photovoltaic module 1 to rotate clockwise relative to the first pressure block 21. That is, F1x can cancel out the force that causes the photovoltaic module 1 to rotate clockwise relative to the first pressure block 21, thereby effectively resisting the clockwise rotation of the photovoltaic module 1. At the same time, when the photovoltaic module 1 rotates clockwise, the frame side plate 13 can abut against the connecting member 24 (as shown in Figure 5). The force applied by the connecting member 24 to the frame side plate 13 can also resist the clockwise rotation of the photovoltaic module 1, improving the installation stability of the photovoltaic module 1 under the heavy snow positive pressure load.

[0086] Scenario 2:

[0087] As shown in Figures 7 and 8, when the photovoltaic module 1 is under a strong wind negative pressure load, the photovoltaic module 1 rotates counterclockwise relative to the first pressure block 21, thereby causing the top plate 11 of the frame to rotate counterclockwise. Because the second distance 2132 between the second tooth surface 1112 and the second side wall 2122 is large, the first tooth structure 111 is not easy to contact the second tooth structure 211. That is, when the wind force is small, the second tooth surface 1112 of the first tooth structure 111 does not abut against the second side wall 2122. Only when the strong wind negative pressure is large enough will the first tooth structure 111 and the second tooth structure 211 come into contact (as shown in Figure 8). In the process, the second tooth surface 1112 contacts the second sidewall 2122. When the first tooth structure 111 abuts against the second tooth structure 211, the second tooth structure 211 applies a force F2 to the first tooth structure 111. The force F2 can be decomposed into a component force F2x parallel to the horizontal direction and a component force F2y parallel to the vertical direction. F2x is opposite to the force that causes the photovoltaic module 1 to rotate counterclockwise. That is, F2x cancels out the force that causes the photovoltaic module 1 to rotate counterclockwise relative to the first pressure block 21, thereby effectively resisting the counterclockwise rotation of the photovoltaic module 1 under the condition of strong wind negative pressure load.

[0088] Preferably, as shown in Figure 3, the central axis of the first sidewall 2121 and the second sidewall 2122 is a, and the central axis of the first tooth surface 1111 and the second tooth surface 1112 is b, wherein the included angle α between a and b is 5°-20°.

[0089] By setting the angle α between a and b within the range of 5°-20°, the first distance 2131 between the first tooth surface 1111 and the first sidewall 2121 in the first direction and the second distance 2132 between the second tooth surface 1112 and the second sidewall 2122 in the first direction can both be controlled within a better range. This avoids the problem of poor contact stability caused by the small contact area between the first tooth surface 1111 and the first sidewall 2121 when the first tooth structure 111 and the second tooth structure 211 come into contact due to the large angle between a and b.

[0090] Preferably, as shown in FIG3, the included angle β between the second tooth surface 1112 and the second direction is in the range of 10°-30°.

[0091] With this configuration, on the one hand, when the photovoltaic module 1 is under a positive pressure load due to heavy snow, when the first tooth structure 111 contacts the second tooth structure 211, the contact area between the first tooth structure 111 (first tooth surface 1111) and the second tooth structure 211 is larger, which helps to improve the contact stability between the first tooth structure 111 and the second tooth structure 211 and prevents the first tooth structure 111 from detaching from the second tooth structure 211. On the other hand, setting β in the range of 10°-30° can also facilitate the improvement of the cooperation effect between the first tooth structure 111 and the second tooth structure 211 and prevent the frame of the module from being unable to rotate due to an excessively small included angle.

[0092] Preferably, as shown in FIG6, the angle between the first sidewall 2121 and the second direction is γ1, wherein γ1 < 45°.

[0093] Specifically, as shown in Figures 5 and 6, under the condition of positive pressure load from heavy snow, when the first toothed structure 111 abuts against the second toothed structure 211, the second toothed structure 211 applies a clamping force F1 to the first toothed structure 111. The angle between F1 and its vertical component F1y is θ1. Since F1 is perpendicular to the first sidewall 2121, then θ1 + γ1 = 90°. When γ1 < 45°, θ1 > 45°, then F1x > F1y. This ensures that the vertical component F1y of the clamping force F applied by the second toothed structure 211 to the first toothed structure 111 is less than its horizontal component F1x. In this way, the larger component F1x can be used to resist the clockwise rotation of the photovoltaic module 1, while the smaller component F1y is applied to the laminate 14. This effectively resists the clockwise rotation of the photovoltaic module 1 and effectively prevents the module frame from pressing on the glass and causing the glass to break.

[0094] Preferably, the angle between the second sidewall 2122 and the second direction is γ2, where γ2 < 45°.

[0095] Specifically, as shown in Figures 7 and 8, under the condition of strong wind negative pressure load, the photovoltaic module 1 rotates counterclockwise relative to the first pressure block 21. When the first toothed structure 111 abuts against the second toothed structure 211, the second toothed structure 211 applies a clamping force F2 to the first toothed structure 111. The angle between F2 and its vertical component force F2y is θ2. Since F2 is perpendicular to the second sidewall 2122, θ2 + γ2 = 90°. When γ2 < 45°, θ2 > 45°. If F2x > F2y, then the vertical component F2y of the clamping force exerted by the second toothed structure 211 on the first toothed structure 111 is less than its horizontal component F2x. In this way, the larger component F2x can be used to resist the counterclockwise rotation of the photovoltaic module 1, while the smaller component F2y can be applied to the laminate 14. This can effectively resist the counterclockwise rotation of the photovoltaic module 1 and effectively prevent the module frame from pressing on the glass and causing the glass to break.

[0096] Preferably, as shown in Figure 3, the width w1 of the first toothed structure 111 near the top plate 11 of the frame is 0.8mm-3mm.

[0097] This design avoids the structural strength of the first tooth structure 111 being too low due to the width of the end of the first tooth structure 111 near the top plate 11 being too small. It also avoids the situation where the number of first tooth structures 111 that can be arranged on the top plate 11 is too small due to the width of the end of the first tooth structure 111 near the top plate 11 being too large, thus preventing the first tooth structure 111 from achieving a good fit with the second tooth structure 211. Furthermore, it avoids the situation where the processing difficulty of the component frame is increased due to the width of the end of the first tooth structure 111 near the top plate 11 being too small.

[0098] Preferably, the width of the tip of the first tooth structure 111 is 0.15mm-0.5mm.

[0099] By setting the width of the tip of the first tooth structure 111 to 0.15mm-0.5mm, it is possible to avoid the first tooth structure 111 from being too small and thus easily deforming and failing when subjected to large loads, thereby ensuring the structural strength of the first tooth structure 111.

[0100] It should be noted that the present invention does not impose any limitations on the specific shape of the tip of the first tooth structure 111.

[0101] In one specific embodiment, as shown in FIG3, the tip of the first tooth structure 111 is an arc-shaped surface.

[0102] In another specific embodiment, the tip of the first tooth structure 111 is a plane (not shown in the figure).

[0103] Preferably, the tip of the first tooth structure 111 is an arc-shaped surface, wherein the radius of the arc-shaped surface is 0.1mm-1mm.

[0104] By setting the tip of the first tooth structure 111 as an arc surface, when the first tooth structure 111 contacts the second tooth structure 211, it helps to increase the contact area between the tip of the first tooth structure 111 and the second tooth structure 211. At the same time, setting the radius of the arc surface to 0.1mm-1mm can avoid the chamfer radius being too small, which would result in the tip of the first tooth structure 111 having too little strength. It can also avoid the chamfer radius being too small, which would increase the processing difficulty of the component frame.

[0105] It should be noted that, in practical applications, those skilled in the art can set the gap 112 to gradually increase along the first direction from one end near the side plate 13 to the end away from the side plate 13. Alternatively, the top plate of the side plate can be set to have a first region and a second region distributed along the first direction, wherein the gap between the tip of the first toothed structure 111 in the second region and the inner wall of the groove 212 in the second direction is greater than the gap between the tip of the first toothed structure 111 in the first region and the inner wall of the groove 212 in the second direction, etc. Such adjustments and changes to the specific setting of the gap 112 gradually increasing along the first direction from one end near the side plate 13 to the end away from the side plate 13 do not deviate from the principle and scope of the present invention and should all be included within the protection scope of the present invention.

[0106] Preferably, as shown in FIG4, the frame top plate 11 has a first region 1121 and a second region 1122 distributed sequentially along a first direction, wherein the thickness D1 of the frame top plate 11 in the first region 1121 in the second direction is greater than the thickness D2 of the frame top plate 11 in the second region 1122 in the second direction, and the gap H1 between the tip of the first tooth structure 111 in the first region 1121 and the inner wall of the groove 212 in the second direction is smaller than the gap H2 between the tip of the first tooth structure 111 in the second region 1122 and the inner wall of the groove 212 in the second direction.

[0107] With this configuration, when the photovoltaic module 1 rotates relative to the first pressure block 21 due to strong winds or heavy snow, the gap H1 in the first region 1121 is smaller than the gap H2 in the second region 1122. Therefore, when the first toothed structure 111 contacts the second toothed structure 211, the first toothed structure 111 in the first region 1121 will preferentially contact and abut against the second toothed structure 211, allowing the first toothed structure 111 in the second region 1122 to subsequently contact the second toothed structure 211, or vice versa. 1. The first pressure block 21 does not contact the second tooth structure 211 (when the load is small), so that the force applied to the photovoltaic module 1 by the first pressure block 21 is more concentrated in the first region 1121 (i.e., the end near the frame side plate 13), which more effectively avoids the pressure applied by the first pressure block 21 from crushing the glass. At the same time, since the thickness of the frame top plate 11 in the first region 1121 is greater than the thickness of the frame top plate 11 in the second region 1122, the force applied to the frame top plate 11 by the first pressure block 21 is concentrated in the region with greater thickness of the frame top plate 11 (i.e., the first region 1121), which can effectively resist the deformation of the frame top plate 11.

[0108] It should be noted that, as shown in Figure 6, when the photovoltaic module 1 is in extreme snowy weather, under the gravity of the snow, the first tooth structure 111 in the second region 1122 will detach from the second tooth structure 211 first, and then the first tooth structure 111 in the first region 1121 will detach from the second tooth structure 211. This provides maintenance personnel with some time for emergency repairs and avoids all the first tooth structures 111 from detaching from the second tooth structure 211 at the same time, which would cause the photovoltaic module 1 to fall off, thus further improving the installation stability of the photovoltaic module 1.

[0109] It should also be noted that the present invention does not limit the specific number of the first tooth structure 111 and the second tooth structure 211. For example, the number of the first tooth structure 111 can be set to three, four, five, six or more, and the second tooth structure 211 can be set in a one-to-one correspondence with the first tooth structure 111, etc. Such adjustments and changes to the specific number of the first tooth structure 111 and the second tooth structure 211 do not deviate from the principle and scope of the present invention, and should all be included within the protection scope of the present invention.

[0110] After multiple verifications, as shown in Figure 4, the best cooperation effect between the bridging module 2 and the photovoltaic module 1 is achieved when the number of the first tooth structure 111 in the first region 1121 is three and the number of the first tooth structure 111 in the second region 1122 is three, and the processing difficulty of the bridging module 2 and the module frame is lower.

[0111] Preferably, as shown in FIG10, the top plate 11 of the frame has a contact portion 113 on the side away from the first toothed structure 111, wherein the contact portion 113 abuts against the laminate 14 of the photovoltaic module 1, the first toothed structure 111 on the side away from the frame side plate 13 is located above the contact portion 113, and the line PQ connecting the vertex P of the first toothed structure 111 and the midpoint Q of the contact portion 113 is perpendicular to the laminate 14.

[0112] With this configuration, when the first pressing block 21 presses down on the top plate 11 of the frame, the force applied by the first pressing block 21 to the first toothed structure 111 can be evenly distributed along the contact portion 113, thereby improving the uniformity of force on each position on the contact portion 113 and preventing the laminate 14 from being crushed due to uneven force on the contact portion 113.

[0113] It should be noted that, in actual installation, those skilled in the art can set one pressure block assembly 2 on each side of the photovoltaic module 1 to fix the photovoltaic module 1 to the flexible support 3, or two pressure block assemblies 2 on each side of the photovoltaic module 1 to fix the photovoltaic module 1 to the flexible support 3, or multiple pressure block assemblies 2 on each side of the photovoltaic module 1 to fix the photovoltaic module 1 to the flexible support 3, and so on. Such adjustments and changes to the specific number of pressure block assemblies 2 on the photovoltaic module 1 do not deviate from the principle and scope of the present invention and should all be included within the protection scope of the present invention.

[0114] As shown in Figure 18, two pressure block components 2 are set on each side of the photovoltaic module 1, wherein the pressure block component 2 located on one side of the photovoltaic module 1 is correspondingly set with the pressure block component 2 located on the other side of the photovoltaic module 1.

[0115] After installation, the photovoltaic module 1 will vibrate under the action of wind. The magnitude and direction of the wind force on different positions of the photovoltaic module 1 are not exactly the same, resulting in different vibration amplitudes at the positions corresponding to each pressure block component 2 on the photovoltaic module 1. If the first pressure block 21 has a certain elasticity, it can balance the deviation of vibration amplitude at different positions of the photovoltaic module 1 and improve the installation stability.

[0116] It should be noted that the elasticity of the first pressure block 21 can be changed by altering the specific structural form of the connecting member 24.

[0117] The following describes in detail the specific embodiments of the connecting member 24 of the present invention with reference to the following examples.

[0118] Example 1:

[0119] As shown in Figures 2, 5 and 7, the connecting member 24 includes a first extension arm 241 extending in a first direction and a second extension arm 242 extending in a second direction. The second extension arm 242 is connected to the first pressure block 21 and is disposed opposite to the side plate 13 of the frame.

[0120] By setting the first extension arm 241, at least a portion of the connecting member 24 can extend along the first direction, thereby giving the first pressure block 21 a certain elasticity. On the one hand, during installation, the elasticity of the first pressure block 21 makes it easier to insert the component frame between the first pressure block 21 and the second pressure block 22, reducing the installation difficulty and helping to improve installation efficiency. On the other hand, since each photovoltaic module 1 needs to be installed on the flexible bracket 3 with multiple pressure block components 2, but the magnitude and direction of the wind force on different positions of the photovoltaic module 1 are not exactly the same, the elasticity of the first pressure block 21 can also balance the deviation of the vibration amplitude at different positions of the photovoltaic module 1, improving the installation stability.

[0121] Meanwhile, the first pressure block 21 is elastic, and when the component frame is subjected to a large force under the positive pressure load of heavy snow, the elasticity of the first pressure block 21 can be used to make the first tooth structure 111 at the end away from the side plate 13 of the frame disengage from the corresponding second tooth structure 211, so as to avoid excessive force and glass breakage.

[0122] Example 2:

[0123] As shown in Figure 9, the connecting member 24 includes a first extension arm 241 extending in a first direction and a second extension arm 242 extending in a second direction. The second extension arm 242 is connected to the first pressure block 21 and is disposed opposite to the side plate 13 of the frame. The pressure block assembly 2 also includes a fixing member 26, which is used to fix the first extension arm 241 to the second pressure block 22.

[0124] By setting the fixing component 26, when the photovoltaic module 1 is installed in an area with high wind speed, the first extension arm 241 can be fixed on the second pressure block 22, thereby reducing the elasticity of the first pressure block 21, reducing the vibration amplitude of the photovoltaic module 1, and pressing the first pressure block 21 tightly on the top of the module frame, assisting the frame base plate 12 in bearing the load, avoiding excessive force on the frame base plate 12 and causing tearing, and thus facilitating flexible adjustment of the elasticity of the first pressure block 21 according to the actual installation situation.

[0125] For example, when photovoltaic modules are installed in areas with wind speeds of 6 or below (13.8 m / s), the elasticity of the first pressure block 21 is increased, and all the first toothed structures 111 and the inner wall of the groove 212 have a gap 112 in the second direction, that is, the first pressure block 21 does not contact the top plate of the frame, and only the bottom plate of the frame bears the load.

[0126] When photovoltaic modules are installed in areas with wind speeds exceeding level 6 (13.8 m / s), the first extension arm 241 can be fixed to the second pressure block 22 by the fastener 26, reducing the elasticity of the first pressure block 21. This allows the first toothed structure 111 near the side plate 13 of the frame to contact the second toothed structure 211, while only the first toothed structure 111 away from the side plate 13 has a gap 112 between it and the inner wall of the groove 212. In other words, the first pressure block 21 contacts the top plate 11 of the frame, assisting the bottom plate 12 of the frame in bearing the load and preventing the bottom plate 12 of the frame from tearing.

[0127] Example 3:

[0128] As shown in Figure 11, the connecting member 24 includes only a second extension arm extending along the second direction. The second extension arm is connected to the first pressure block 21 and is disposed opposite to the side plate 13 of the frame.

[0129] In this case, the first pressure block 21 has weak elasticity and can reduce the vibration amplitude of the photovoltaic module 1, making it suitable for installation and use in areas with high wind speeds.

[0130] It should be noted that although the present invention is described using the above three embodiments to illustrate the connecting member 24 of the present invention, this is not restrictive. Any other structural form that can connect the first pressing block 21 and the second pressing block 22 does not deviate from the principle and scope of the present invention and should be included within the protection scope of the present invention.

[0131] It should also be noted that, in practical applications, those skilled in the art can set the connecting member 24 to have a uniform cross-sectional thickness at all points, or the connecting member 24 can be set to have a cross-sectional thickness that gradually decreases along its extension direction, etc. Such adjustments and changes to the cross-sectional thickness of the connecting member 24 do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0132] Preferably, as shown in Figures 2, 5 and 9, the connecting member 24 extends from the second pressing block 22 to the first pressing block 21, and the cross-sectional thickness of the connecting member 24 gradually decreases along its extending direction.

[0133] This setup further increases the elasticity of the first pressure block 21, thereby better balancing the vibration amplitude deviation at different positions of the photovoltaic module 1 and further improving installation stability.

[0134] It should be noted that, in practical applications, those skilled in the art can set the cross-sectional thickness of the first extension arm 241 and the second extension arm 242 to gradually decrease along their extension direction, or they can set only the cross-sectional thickness of the first extension arm 241 to gradually decrease along its extension direction, or they can set only the cross-sectional thickness of the second extension arm 242 to gradually decrease along its extension direction, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0135] Preferably, as shown in Figures 2, 5, 7 and 9, the cross-sectional thickness of the first extension arm 241 and the second extension arm 242 gradually decreases along their extension direction.

[0136] It should also be noted that, in practical applications, those skilled in the art can configure the first pressing block 21 and the second pressing block 22 to be fixedly connected to the connecting member 24 by fasteners, or the first pressing block 21 and the second pressing block 22 can be integrally configured with the connecting member 24, or one of the first pressing block 21 and the second pressing block 22 can be fixedly connected to the connecting member 24 by fasteners, and the other of the first pressing block 21 and the second pressing block 22 can be integrally configured with the connecting member 24, etc. Such adjustments and changes to the specific connection methods of the first pressing block 21, the second pressing block 22 and the connecting member 24 do not deviate from the principles and scope of the present invention, and should all be included within the protection scope of the present invention.

[0137] Preferably, the first pressing block 21 and the second pressing block 22 are integrally formed with the connecting member 24.

[0138] It should be noted that, in practical applications, those skilled in the art can configure the connecting member 24 as a connecting plate, or as a connecting rod, etc. Such adjustments and changes to the specific configuration type of the connecting member 24 do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0139] Preferably, the connecting member 24 is a connecting plate.

[0140] Preferably, as shown in Figures 2, 5, 7 and 9, the end of the connecting member 24 near the second pressure block 22 has a reinforcing structure 243.

[0141] By setting the reinforcing structure 243, the connection strength between the connecting member 24 and the second pressure block 22 can be improved, thereby improving the installation stability of the photovoltaic module 1.

[0142] It should be noted that, in practical applications, those skilled in the art can set the reinforcing structure 243 as a reinforcing armpit, or as a reinforcing rib, or as any other possible form, etc. Such adjustments and changes to the specific structural form of the reinforcing structure 243 do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0143] Preferably, as shown in Figures 2, 5, 7 and 9, the reinforcing structure 243 is a reinforcing armpit.

[0144] It should be noted that the present invention does not limit the specific method of fixing the second pressure block 22 to the flexible support 3, as long as the second pressure block 22 can be fixed to the flexible support 3. For example, the second pressure block 22 can be fixed to the flexible support 3 by setting a clamp, or a third pressure block 23 and a locking member can be set, the locking member can lock the second pressure block 22 and the third pressure block 23 to clamp the flexible support 3 between the second pressure block 22 and the third pressure block 23, etc. Such adjustments and changes to the specific method of fixing the second pressure block 22 to the flexible support 3 do not deviate from the principle and scope of the present invention, and should all be included within the protection scope of the present invention.

[0145] Preferably, as shown in Figures 2, 5, 7, 9 and 12, the pressure block assembly 2 of the present invention further includes a third pressure block 23 and a locking member. The third pressure block 23 is disposed on the side of the second pressure block 22 away from the first pressure block 21. The locking member is used to lock the second pressure block 22 and the third pressure block 23. When installed, the flexible bracket 3 is clamped between the second pressure block 22 and the third pressure block 23.

[0146] By setting the third pressure block 23 and the locking component, the flexible bracket 3 can be clamped between the second pressure block 22 and the third pressure block 23, thereby fixing the photovoltaic module 1 on the flexible bracket 3. At the same time, the contact area between the pressure block component 2 and the flexible bracket 3 is increased, thereby improving the fixing stability of the pressure block component 2 on the flexible bracket 3.

[0147] It should be noted that the present invention does not limit the specific structural form of the locking component, as long as it can lock the second pressure block 22 and the third pressure block 23 and clamp the flexible bracket 3 between the second pressure block 22 and the third pressure block 23. For example, the locking component can be configured to include a locking bolt and a locking nut, with locking holes adapted to the locking bolt on the second pressure block 22 and the third pressure block 23. The locking bolt passes through the locking hole and is connected to the locking nut. Alternatively, the locking component can be configured to include only the locking bolt, with a threaded hole adapted to the locking bolt on the third pressure block 23. The locking bolt engages with the threaded hole to clamp the flexible support 3 between the second pressure block 22 and the third pressure block 23. Or, the locking component can be configured to include a first snap-fit ​​structure on the second pressure block 22 and a second snap-fit ​​structure on the third pressure block 23. The first snap-fit ​​structure and the second snap-fit ​​structure engage to clamp the flexible support 3 between the second pressure block 22 and the third pressure block 23. Such adjustments and changes to the specific structural type of the locking component do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0148] Preferably, as shown in Figures 2, 5, 7, 12 and 9, the locking component includes a locking bolt and a locking nut. The second pressure block 22 and the third pressure block 23 are provided with locking holes adapted to the locking bolt. The locking bolt passes through the locking hole and is connected to the locking nut.

[0149] Specifically, as shown in Figure 16, the second pressure block 22 is provided with a first locking hole 221, and the third pressure block 23 is provided with a second locking hole 231.

[0150] It should be noted that, in practical applications, those skilled in the art can either set both the first locking hole 221 and the second locking hole 231 as circular holes, or both as elongated holes, or one of the first locking hole 221 and the second locking hole 231 as a circular hole and the other as an elongated hole, etc. Such adjustments and changes to the specific shape of the first locking hole 221 and the second locking hole 231 do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0151] Preferably, the first locking hole 221 and the second locking hole 231 are oblong holes.

[0152] This setup avoids installation difficulties caused by construction errors, thus improving installation efficiency.

[0153] It should be noted that, in practical applications, those skilled in the art can set the number of locking components to one, or two, or even multiple, etc. Such adjustments and changes to the specific number of locking components do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0154] Preferably, the number of locking components is set to four, namely a first locking component 251, a second locking component 252, a third locking component 253, and a fourth locking component 254.

[0155] Specifically, as shown in Figures 2, 5, 7, 9, 12 to 16, the first locking member 251 and the second locking member 252 are located on the left side of the connecting member 24, and the third locking member 253 and the fourth locking member 254 are located on the right side of the connecting member 24. The first locking member 251 and the second locking member 252 are located on both sides of the flexible bracket 3, and the third locking member 253 and the fourth locking member 254 are located on both sides of the flexible bracket 3.

[0156] It should be noted that the third locking member 253 and the fourth locking member 254 are also used to fix the frame base plate 12 onto the second pressure block 22.

[0157] With this setup, the frame base plate 12 can be fixed to the second pressure block 22 while fixing the second pressure block 22 and the third pressure block 23. This not only reduces the number of parts used but also improves installation efficiency.

[0158] Of course, a locking device can also be used to fix the frame base plate 12 to the second pressure block 22.

[0159] It should be noted that when fixing the first extension arm 241 to the second pressure block 22, the fixing member 26 can be configured to fix the first extension arm 241 only to the second pressure block 22, or the fixing member 26 can be configured to fix the first extension arm 241 to both the second pressure block 22 and the third pressure block 23, etc. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention and should be included within the protection scope of the present invention.

[0160] Preferably, as shown in FIG9, the fastener 26 is used to fix the first extension arm 241 to the second pressure block 22 and the third pressure block 23.

[0161] It should be noted that the structure of the fastener 26 is the same as that of the locking component, and will not be described again here.

[0162] Preferably, as shown in Figures 12 to 14, the second pressure block 22 is provided with a first limiting structure 222 adapted to the flexible support 3, and the third pressure block 23 is provided with a second limiting structure 232 adapted to the flexible support 3. When installed, a portion of the flexible support 3 is located within the first limiting structure 222 and the second limiting structure 232.

[0163] By setting limiting structures on the second pressure block 22 and the third pressure block 23, the flexible support 3 can be limited, preventing the flexible support 3 from sliding between the second pressure block 22 and the third pressure block 23, thereby further improving the installation stability of the photovoltaic module 1.

[0164] It should be noted that the invention is not limited to providing the first limiting structure 222 on the second pressing block 22 and the second limiting structure 232 on the third pressing block 23. For example, the first limiting structure 222 may be provided only on the second pressing block 22, or the second limiting structure 232 may be provided only on the third pressing block 23, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention. Of course, it is preferable to provide the first limiting structure 222 on the second pressing block 22 and the second limiting structure 232 on the third pressing block 23.

[0165] It should also be noted that the present invention does not limit the specific connection method between the second pressing block 22 and the third pressing block 23. For example, the third pressing block 23 can be set to be separate from the second pressing block 22, or the third pressing block 23 can be set to be connected to the second pressing block 22 through a connector, etc. Such adjustments and changes to the specific connection method between the second pressing block 22 and the third pressing block 23 do not deviate from the principle and scope of the present invention, and should all be included within the protection scope of the present invention.

[0166] In one specific embodiment, as shown in FIG12, the third pressing block 23 is configured to be separate from the second pressing block 22.

[0167] During installation, first align the first locking hole 221 with the second locking hole 231, and then pass the locking bolt through the first locking hole 221 and the second locking hole 231 in sequence to clamp the flexible bracket 3 between the second pressure block 22 and the third pressure block 23.

[0168] In another specific embodiment, as shown in Figures 13, 14 and 16, the pressure block assembly 2 further includes a hinge 27, and the third pressure block 23 is configured to be connected to the second pressure block 22 via the hinge 27. The third pressure block 23 is rotatable relative to the second pressure block 22 to clamp the flexible support 3 between the third pressure block 23 and the second pressure block 22.

[0169] During installation, simply rotate the third pressure block 23 relative to the second pressure block 22 to align the first locking hole 221 with the second locking hole 231, and then pass the locking bolt through the first locking hole 221 and the second locking hole 231 in sequence to clamp the flexible bracket 3 between the second pressure block 22 and the third pressure block 23.

[0170] This setup improves the overall integrity of the briquetting component 2, saving on-site assembly time and facilitating its transportation, thus enhancing installation and transport convenience. Furthermore, during photovoltaic module 1 installation, there is no need for on-site alignment by staff; the briquetting component 2 can be pre-installed onto the photovoltaic module 1 and then locked in place by locking components, significantly improving the installation efficiency of the photovoltaic module 1.

[0171] It should be noted that the present invention does not limit the specific type of hinge 27, as long as it enables the hinged connection between the second pressing block 22 and the third pressing block 23. For example, the hinge 27 can be configured as a hinge, or as a rotating hinge, or in any other possible form, etc. Such adjustments and changes to the specific type of hinge 27 do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0172] Preferably, the hinge 27 is a rotary hinge.

[0173] It should be noted that the pressing component 2 of the present invention can be a side pressing component 201, or the pressing component 2 can also be a middle pressing component 202, which is located between two adjacent photovoltaic modules 1. Alternatively, the pressing component 2 can also be a combination of the side pressing component 201 and the middle pressing component 202, etc. Such adjustments and changes to the specific type of the pressing component 2 do not deviate from the principle and scope of the present invention and should all be included within the protection scope of the present invention.

[0174] In one specific embodiment, as shown in FIG1, the pressing assembly 2 includes a side pressing assembly 201, and the two side pressing assemblies 201 are respectively located on both sides of the photovoltaic module 1.

[0175] In another specific embodiment, as shown in FIG17, the pressure block assembly 2 includes a side pressure block assembly 201 and a middle pressure block assembly 202, wherein the middle pressure block assembly 202 is located between two adjacent photovoltaic modules 1, and the side pressure block assembly 201 is disposed on the side of the photovoltaic module 1 away from the middle pressure block assembly 202.

[0176] Specifically, the middle pressure block assembly 202 includes a first pressure block 21, a second pressure block 22, a third pressure block 23, a connecting member 24, and a locking member. There are two first pressure blocks 21, and the two first pressure blocks 21 extend in opposite directions. There are two connecting members 24, and the two connecting members 24 are respectively arranged in a one-to-one correspondence with the two first pressure blocks 21. The locking member is used to clamp the flexible support 3 between the second pressure block 22 and the third pressure block 23.

[0177] Specifically, as shown in Figure 17, the pressure block assembly 2 consists of a side pressure block assembly 201 and a middle pressure block assembly 202. There are two photovoltaic modules 2, namely a first photovoltaic module 101 and a second photovoltaic module 102. The middle pressure block assembly 202 is located between the first photovoltaic module 101 and the second photovoltaic module 102. The two first pressure blocks 21 of the middle pressure block assembly 202 are located above the top plate 11 of the frame of the first photovoltaic module 101 and the second photovoltaic module 102, respectively. The side pressure block assembly 201 is located on the side of the first photovoltaic module 101 and the second photovoltaic module 102 away from the middle pressure block assembly 202.

[0178] By setting the middle pressure block component 202, it is easy to fix two adjacent photovoltaic modules 1 on the flexible bracket 3, reducing the number of pressure block components 2 used. At the same time, the side pressure block component 201 and the middle pressure block component 202 work together to be used flexibly according to actual installation needs.

[0179] In a second aspect, the present invention also provides a component frame having a top plate 11, a bottom plate 12, and a side plate 13. The top plate 11 is provided with a plurality of first tooth-shaped structures 111 arranged sequentially along a first direction. The component frame is combined with the pressing block component 2 described in the first aspect and fixes the photovoltaic module 1 on the flexible support 3.

[0180] In a third aspect, the present invention also provides a photovoltaic module 1, the photovoltaic module 1 including a laminate 14 and the module frame described in the second aspect.

[0181] In a fourth aspect, the present invention also provides a photovoltaic system, the photovoltaic system comprising the pressing block assembly 2 described in the first aspect, the photovoltaic module 1 described in the third aspect, and a flexible support 3, the flexible support 3 being used to support the photovoltaic module 1, and the pressing block assembly 2 being used to fix the photovoltaic module 1 onto the flexible support 3.

[0182] The specific process of installing the photovoltaic modules of the present invention is described in detail below.

[0183] First, the component frame is inserted between the first pressure block 21 and the second pressure block 22 to pre-install the pressure block assembly 2 onto the photovoltaic module 1. Then, the photovoltaic module 1 is moved to the already installed flexible bracket 3, and the pressure block assembly 2 slides along the component frame to the position corresponding to the flexible bracket 3. The flexible bracket 3 is then positioned within the first limiting structure 222, and the third pressure block 23 rotates relative to the second pressure block 22 so that the first locking hole 221 aligns with the second locking hole 231. The locking bolts at each position are passed through the first locking hole 221 and the second locking hole 231 in sequence and connected to the corresponding locking nuts, so that the flexible bracket 3 is clamped between the second pressure block 22 and the third pressure block 23. A fixing component 26 can also be added according to the actual installation environment to fix the first extension arm 241 onto the second pressure block 22 and the third pressure block 23, thus completing the installation of the photovoltaic module 1.

[0184] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
