[0002] A photovoltaic module is a device that can use the photovoltaic effect to directly convert light energy into electrical energy. A photovoltaic module usually includes a module frame and a laminate. When the photovoltaic module is installed, the module frame is fixed to the photovoltaic bracket.

[0003] Flexible photovoltaic brackets have strong adaptability and can be adjusted and installed according to different installation environments to meet the installation requirements of different sites. The installation of photovoltaic modules on flexible photovoltaic brackets is usually done by fixing the photovoltaic modules on the tensioned steel strands through a clamping assembly.

[0015] In the preferred technical solution of the above-mentioned block assembly, the photovoltaic assembly also includes a laminate, and the side of the frame top plate away from the first tooth-shaped structure has a contact portion, wherein the first tooth-shaped structure away from the side of the frame side plate is located above the contact portion and the line between the vertex of the first tooth-shaped structure and the midpoint of the contact portion is perpendicular to the laminate.

[0016] In the preferred technical solution of the above-mentioned 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 also includes a fixing member, which is used to fix the first extension arm on 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 arranged opposite to the frame side plate.

[0017] In a preferred technical solution of the above-mentioned pressing block assembly, the connecting member extends in a direction from the second pressing block to the first pressing block, and a cross-sectional thickness of the connecting member gradually decreases along its extending direction.

[0018] In the preferred technical solution of the above-mentioned pressure block assembly, the pressure block assembly also includes a third pressure block and a locking member, and 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.

[0019] In the preferred technical solution of the above-mentioned pressure block assembly, the locking component is a locking bolt and a locking nut, and the second pressure block and the third pressure block are provided with locking holes compatible with the locking bolt, and 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 compatible with the flexible bracket, and when installed, a part of the flexible bracket is located in the limiting structure.

[0020] In a preferred technical solution of the above-mentioned pressing block assembly, the pressing block assembly further comprises a hinge, and the second pressing block and the third pressing block are hingedly connected via the hinge.

[0021] In a second aspect, the present invention provides a component frame, which has a frame top plate, a frame bottom plate and a frame side plate, and a plurality of first tooth-shaped structures arranged in sequence along a first direction are arranged on the frame top plate. The component frame is combined with the pressing block assembly described in the first aspect and fixes the photovoltaic component on the flexible bracket.

[0022] In a third aspect, the present invention provides a photovoltaic module, comprising a laminate and the module frame according to the second aspect.

[0023] In a fourth aspect, the present invention further provides a photovoltaic system, comprising the pressing block assembly described in the first aspect, the photovoltaic assembly described in the third aspect, and a flexible bracket, wherein the flexible bracket is used to support the photovoltaic assembly.

[0024] In the preferred technical scheme of the above-mentioned pressing block assembly, by arranging the first pressing block at a position corresponding to the frame top plate and the second pressing block at a position corresponding to the frame bottom plate, it is possible to prevent the frame bottom plate from tearing under strong wind loads and prevent the photovoltaic components from falling off. At the same time, through the cooperation of the first tooth-shaped structure and the second tooth-shaped structure, it is possible not only to prevent the photovoltaic components from shaking left and right, but also to prevent the laminate from being compressed due to excessive deformation of the edge of the component frame under heavy snow loads, thereby effectively preventing the glass of the laminate from being crushed.

[0025] Furthermore, by providing a gap between the tip of the first tooth-shaped structure and the side wall of the groove in the second direction and gradually increasing the gap along the first direction from the end close to the frame side panel to the end away from the frame side panel, when the first pressure block is pressed against the top plate of the frame, on the one hand, the pressing force between the end of the first pressure block close to the frame side panel and the top plate of the frame can be larger, and the pressing force between the end of the first pressure block away from the frame side panel and the top plate of the frame can be smaller, so that the pressing force applied by the first pressure block to the component frame is transmitted from the position of the frame side panel as much as possible, thereby more effectively avoiding crushing of the glass. On the other hand, when the photovoltaic component is under a heavy snow positive pressure load, it can avoid crushing of the glass due to excessive deformation of the edge of the component frame under the heavy snow load.

[0026] Furthermore, the depth of the groove is set to gradually increase along the first direction from the end close to the frame side panel to the end away from the frame side panel, so that the cross-sectional thickness of the first pressing block can be gradually reduced along the first direction from the end close to the frame side panel to the end away from the frame side panel, so that the first pressing block has elasticity. On the one hand, it can facilitate the insertion of the photovoltaic component between the first pressing block and the second pressing block to improve the installation efficiency. On the other hand, it can balance the vibration amplitude at different positions on the photovoltaic component to improve the installation stability of the photovoltaic component. At the same time, in extreme snowy weather, the elasticity of the first pressing block can also enable the first toothed structure away from the end of the frame side panel to disengage from the corresponding second toothed structure, thereby avoiding the crushing of glass due to excessive deformation of the component frame.

[0027] Furthermore, by setting the distance between the first tooth surface and the first side wall to be smaller than the distance between the second tooth surface and the second side wall, on the one hand, when the photovoltaic assembly is under a positive pressure load of heavy snow, it can effectively resist the clockwise rotation of the photovoltaic assembly, and when the photovoltaic assembly is under a negative pressure load of strong wind, it can effectively resist the counterclockwise rotation of the photovoltaic assembly, thereby improving the installation stability of the photovoltaic assembly; on the other hand, when the first tooth-shaped structure contacts the second tooth-shaped structure, the horizontal component of the pressing force applied by the first pressure block to the top plate of the frame can be used to resist the rotation of the photovoltaic assembly, and the vertical component of the pressing force is applied to the laminate, thereby avoiding excessive pressing force applied to the laminate and crushing the glass.

[0028] Furthermore, by controlling the angle α between a and b within the range of 5°-20°, the first distance between the first tooth surface and the first side wall in the first direction and the second distance between the second tooth surface and the second side wall in the first direction can be controlled within a preferred range, which can avoid the problem of poor abutment stability due to the small contact area between the first tooth surface and the first side wall when the first tooth structure contacts the second tooth structure due to the excessively large angle between a and b.

[0029] Furthermore, the angle β between the second tooth surface and the vertical direction is set to 10°-30°. On the one hand, when the photovoltaic component is under a heavy snow positive pressure load, when the first tooth structure contacts the second tooth structure, the contact area between the first tooth structure (first tooth surface) and the second tooth structure can be larger, which helps to improve the abutment stability between the first tooth structure and the second tooth structure and prevent the first tooth structure from escaping from the second tooth structure; on the other hand, it can also facilitate improving the coordination effect between the first tooth structure and the second tooth structure and prevent the component frame from being unable to rotate due to the angle being too small.

[0030] Furthermore, the angle γ1 between the first side wall and the second direction is set to be less than 45°. When the photovoltaic component is under a positive pressure load of heavy snow, when the first tooth-shaped structure comes into contact with the second tooth-shaped structure, the larger component of the clamping force can be used to resist the clockwise rotation of the photovoltaic component, while the smaller component is applied to the laminate, which can effectively resist the rotation of the photovoltaic component and effectively prevent the component frame from compressing the glass to cause the glass to shatter; the angle γ2 between the second side wall and the second direction is set to be less than 45°. When the photovoltaic component is under a negative pressure load of strong wind, when the first tooth-shaped structure comes into contact with the second tooth-shaped structure, the larger component of the clamping force can be used to resist the counterclockwise rotation of the photovoltaic component, while the smaller component is applied to the laminate, which can effectively resist the rotation of the photovoltaic component and effectively prevent the component frame from compressing the glass to cause the glass to shatter.

[0031] Furthermore, by making the gap H1 in the first area smaller than the gap H2 in the second area, on the one hand, the first tooth-shaped structure in the first area can preferentially contact the second tooth-shaped structure, and the first tooth-shaped structure in the second area can contact (or not contact) the second tooth-shaped structure later, so that the pressing force applied by the first pressure block to the frame assembly is more concentrated in the first area, and the pressing force applied by the first pressure block to the frame assembly is more effectively avoided to crush the glass. At the same time, since the thickness of the frame top plate in the first area is greater than its thickness in the second area, the force applied by the first pressure block to the frame top plate can be mainly concentrated in the area with a larger thickness of the frame top plate, effectively resisting deformation of the frame top plate; on the other hand, when the photovoltaic assembly is under an extreme heavy snow positive pressure load, the first tooth-shaped structure in the second area can preferentially detach from the second tooth-shaped structure, and the first tooth-shaped structure in the first area can detach from the second tooth-shaped structure later, providing maintenance personnel with a certain amount of emergency repair time, avoiding all the first tooth-shaped structures from detaching from the second tooth-shaped structure at the same time to cause the photovoltaic assembly to fall off, and further improving the installation stability of the photovoltaic assembly.

[0032] Furthermore, the connecting member is configured to include a first extension arm extending along a first direction and a second extension arm extending along a second direction, and / or the cross-sectional thickness of the connecting member is gradually reduced along its extension direction, so that the first pressing block can have a certain elasticity. On the one hand, during installation, it is convenient to use the elasticity of the first pressing block to make the component frame fit between the first pressing block and the second pressing block, thereby reducing the difficulty of installation and helping to improve installation efficiency; on the other hand, the first pressing block having a certain elasticity can also balance the deviation of the vibration amplitude at different positions of the photovoltaic component and improve the installation stability. At the same time, the first pressing block has elasticity and can also, under the condition of heavy snow positive pressure load, when the component frame is subjected to a large force, use the elasticity of the first pressing block to make the first toothed structure away from the end of the frame side panel disengage from the corresponding second toothed structure, thereby avoiding excessive force and causing glass to break.

[0033] Furthermore, by providing a fixing part, when the photovoltaic module is installed in an area with a higher wind speed, the first extension arm can be fixed on the second pressing block, thereby reducing the elasticity of the first pressing block and the vibration amplitude of the photovoltaic module, so that the first pressing block is pressed tightly on the top of the module frame, and the auxiliary frame bottom plate jointly bears the load, avoiding excessive force on the frame bottom plate and causing tearing, thereby facilitating the flexible adjustment of the elasticity of the first pressing block according to the actual installation situation.

[0034] Furthermore, by arranging the second pressing block and the third pressing block to be connected by a hinge, on the one hand, the integrity of the pressing block assembly can be improved, which not only saves time for on-site assembly, but also facilitates the transportation of the pressing block assembly, thereby improving the convenience of installation and transportation; on the other hand, when installing the photovoltaic module, there is no need for staff to align holes on site, and the pressing block assembly can be pre-installed on the photovoltaic module and then locked by a locking member, thereby greatly improving the installation efficiency of the photovoltaic module.

[0035] In addition, the photovoltaic system further provided by the present invention on the basis of the above-mentioned technical solution, because it includes the above-mentioned pressing block assembly, thus has the beneficial effects of the above-mentioned pressing block assembly. Compared with the photovoltaic system before the improvement, the photovoltaic system of the present invention is more capable of withstanding strong winds and heavy snow loads, the photovoltaic components are less likely to fall off, and the installation stability is higher.

DETAILED DESCRIPTION

[0057] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0058] It should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "inner", "top", "bottom" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0059] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "setting" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0060] like Figures 1 to 10 As shown, the photovoltaic module 1 of the present invention includes a module frame and a laminate 14, wherein the module frame is arranged at the edge of the laminate 14, and the module frame has a frame top plate 11, a frame bottom plate 12 and a frame side plate 13, wherein a plurality of first tooth-shaped structures 111 arranged in sequence along a first direction are arranged on the frame top plate 11.

[0061] like Figures 1 to 10 As shown, the pressing block assembly 2 is used to fix the photovoltaic assembly 1 on the flexible bracket 3, wherein the pressing block assembly 2 includes a first pressing block 21, a second pressing block 22 and a connecting member 24, the first pressing block 21 is arranged opposite to the frame top plate 11, and a plurality of second tooth-shaped structures 211 arranged in sequence along the first direction are arranged on the side of the first pressing block 21 close to the frame top plate 11, the second pressing block 22 is arranged opposite to the frame bottom plate 12 and can be fixedly connected to the frame bottom plate 12, the second pressing block 22 can be fixed on the flexible bracket 3, the connecting member 24 is arranged opposite to the frame side plate 13, and the two ends of the connecting member 24 are respectively connected to the first pressing block 21 and the second pressing block 22.

[0062] 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 pressing block 21 along a first direction and allow the component frame to move relative to the first pressing block 21 along a second direction, wherein the first direction is perpendicular to the second direction.

[0063] It should be noted that if Figure 3 , Figure 4 , Figure 6 , Figure 8 and Fig.10 As shown, the first direction is the horizontal direction, and the second direction is the vertical direction.

[0064] Through such an arrangement, on the one hand, by respectively arranging the first pressing block 21 and the second pressing block 22 relative to the frame top plate 11 and the frame bottom plate 12 of the component frame, the vibration amplitude of the frame top plate 11 can be reduced, thereby preventing the frame bottom plate 12 from tearing in strong winds, thereby preventing the photovoltaic component 1 from falling off, and avoiding the installation complexity caused by using multiple pressing blocks; on the other hand, through the cooperation of the first toothed structure 111 and the second toothed structure 211, not only can the component frame be prevented from moving in the first direction relative to the first pressing block 21, thereby preventing the photovoltaic component 1 from shaking left and right, but also allowing the component frame to move in the second direction relative to the first pressing block 21, so as to avoid the laminate 14 being compressed due to excessive deformation of the edge of the component frame under heavy snow load, thereby preventing the glass of the laminate 14 from being crushed. In addition, the arrangement of the first toothed structure 111 and the second toothed structure 211 can also help to pre-install the pressing block assembly 2 on the photovoltaic component 1 to prevent the pressing block assembly 2 from falling off the photovoltaic component 1.

[0065] It should be noted that, in actual applications, those skilled in the art may arrange the first tooth-shaped structure 111 and the second tooth-shaped structure 211 to be alternately distributed in sequence along the first direction, that is, two adjacent second tooth-shaped structures 211 form a groove 212, and when installed, the first tooth-shaped structure 111 is located in the groove 212, or the number of the first tooth-shaped structures 111 may be arranged to be greater than the number of the second tooth-shaped structures 211, that is, two adjacent second tooth-shaped structures 211 form a groove 212, and when installed, at least part of the first tooth-shaped structures 111 is located in the groove 212, or the number of the second tooth-shaped structures 211 may be arranged to be greater than the number of the first tooth-shaped structures 111, that is, two adjacent second tooth-shaped structures 211 form a groove 212, and the first tooth-shaped structure 111 is located in part of the groove 212, and so on. Such adjustments and changes to the specific distribution methods of the first tooth-shaped structures 111 and the second tooth-shaped structures 211 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0066] Preferably, if Figure 3 and Fig.10 As shown, a groove 212 is formed between two adjacent second tooth-shaped structures 211. When installed, the first tooth-shaped structure 111 is located in the groove 212. A gap 112 exists between the tip of at least part of the first tooth-shaped structure 111 and the inner wall of the groove 212 in the second direction, and the gap 112 gradually increases along the first direction from the end close to the frame side plate 13 to the end away from the frame side plate 13.

[0067] By gradually increasing the gap 112 along the first direction from the end close to the frame side panel 13 to the end away from the frame side panel 13, when the first pressing block 21 is pressed against the frame top panel 11, on the one hand, the pressing force between the end of the first pressing block 21 close to the frame side panel 13 and the frame top panel 11 can be larger, and the pressing force between the end of the first pressing block 21 away from the frame side panel 13 and the frame top panel 11 can be smaller, so that the pressing force applied by the first pressing block 21 to the component frame is transmitted from the position of the frame side panel 13 as much as possible, thereby more effectively avoiding crushing of the glass; on the other hand, when the photovoltaic component 1 is under a heavy snow positive pressure load, it can avoid crushing of the glass due to excessive deformation of the edge of the component frame under the heavy snow load.

[0068] It should be noted that the gap 112 herein refers to the distance between the tip of the first tooth-shaped structure 111 and the inner wall of the groove 212 in the second direction.

[0069] For example, Figure 3 and Fig.10 As shown, the gap 112 between the first tooth-shaped structure 111 and the inner wall of the corresponding groove 212 in the second direction is H.

[0070] It should be noted that, in actual applications, only the tips of some of the first tooth-shaped structures 111 and the inner walls of the grooves 212 have gaps 112 in the second direction, or, the tips of all the first tooth-shaped structures 111 and the inner walls of the grooves 212 have gaps 112 in the second direction, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be included in the protection scope of the present invention.

[0071] In a specific embodiment, Figure 3 As shown, all the first tooth structures 111 and the inner wall of the groove 212 have a gap 112 in the second direction.

[0072] When the photovoltaic module 1 is installed under normal weather conditions, the frame bottom plate 12 of the photovoltaic module 1 is fixedly connected to the second pressing block 22, that is, at this time, only the frame bottom plate 12 bears the load, and the first pressing block 21 does not apply a clamping force to the frame top plate 11. There is a gap 112 between the frame top plate 11 and the first pressing block 21, which can ensure that the photovoltaic module 1 has a certain buffer space when vibrating. When the vibration amplitude is small, the frame top plate 11 will not contact the first pressing block 21. When the vibration amplitude is large, the frame top plate 11 will contact the first pressing block 21 during the vibration process, and the vibration amplitude of the photovoltaic module 1 is reduced under the action of the first pressing block 21.

[0073] In another specific embodiment, Fig.10As shown, only the tip of the first toothed structure 111 away from the frame side plate 13 and the inner wall of the groove 212 have a gap 112 in the second direction, and the gap 112 gradually increases along the first direction from the end close to the frame side plate 13 to the end away from the frame side plate 13.

[0074] Through such an arrangement, the tip of the first tooth-shaped structure 111 close to the frame side plate 13 abuts against the inner wall of the groove 212, and only the tip of the first tooth-shaped structure 111 away from the frame side plate 13 and the inner wall of the groove 212 have a gap 112 in the second direction. On the one hand, when the photovoltaic module 1 is installed under a large wind load, the side of the frame top plate 11 close to the frame side plate 13 can contact the first pressing block 21, and the first pressing block 21 applies a pressing force to the frame top plate 11, and the auxiliary frame bottom plate 12 jointly bears the strong wind load. On the other hand, the clamping force between the end of the first pressing block 21 close to the frame side plate 13 and the frame top plate 11 can be larger, and the clamping force between the end of the first pressing block 21 away from the frame side plate 13 and the frame top plate 11 can be smaller, so that the clamping force applied by the first pressing block 21 to the component frame is transmitted from the position of the frame side plate 13 as much as possible, thereby avoiding the clamping force of the first pressing block 21 from being transmitted from the laminate 14 to the photovoltaic component 1, and more effectively avoiding crushing of the glass.

[0075] It should be noted that, in actual applications, those skilled in the art may set the depth of the groove 212 to gradually increase along the first direction from one end close to the frame side panel 13 to one end away from the frame side panel 13, so that the gap 112 gradually increases along the first direction from one end close to the frame side panel 13 to one end away from the frame side panel 13, or, the height of the first tooth-shaped structure 111 may be set to gradually decrease along the first direction from one end close to the frame side panel 13 to one end away from the frame side panel 13, so that the gap 112 gradually increases along the first direction from one end close to the frame side panel 13 to one end away from the frame side panel 13, and so on. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0076] Preferably, the depth of the groove 212 gradually increases along the first direction from an end close to the frame side plate 13 to an end far away from the frame side plate 13 .

[0077] Through such a configuration, the cross-sectional thickness of the first pressing block 21 can be gradually reduced along the first direction from the end close to the frame side panel 13 to the end away from the frame side panel 13, so that the first pressing block 21 has elasticity. On the one hand, it can facilitate the insertion of the photovoltaic component 1 between the first pressing block 21 and the second pressing block 22 to improve the installation efficiency. On the other hand, it can balance the vibration amplitude at different positions on the photovoltaic component 1 to improve the installation stability of the photovoltaic component 1. At the same time, in extreme snowy weather, the elasticity of the first pressing block 21 can also enable the first toothed structure 111 and the corresponding second toothed structure 211 to separate from each other at the end away from the frame side panel 13, thereby avoiding crushing of glass due to excessive deformation of the component frame.

[0078] Specifically, the depth of the groove 212 ranges from 1 mm to 5 mm.

[0079] It should be noted that, in practical applications, those skilled in the art may set the distances between the two tooth surfaces of the first tooth-shaped structure 111 and the two adjacent second tooth-shaped structures 211 to be equal, or may set the distance between one of the tooth surfaces of the first tooth-shaped structure 111 and the adjacent second tooth-shaped structure 211 to be greater than the distance between the other tooth surface and the adjacent second tooth-shaped structure 211, and so on. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0080] Preferably, if Figure 3 As shown, the groove 212 has a first side wall 2121 and a second side wall 2122, and the distance between the first side wall 2121 and the connecting member 24 in the first direction is greater than the distance between the second side wall 2122 and the connecting member 24 in the first direction, and the first tooth-shaped structure 111 has a first tooth surface 1111 and a second tooth surface 1112, and 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, and when installed, the first distance 2131 between the first tooth surface 1111 and the first side wall 2121 in the first direction is smaller than the second distance 2132 between the second tooth surface 1112 and the second side wall 2122 in the first direction.

[0081] By setting the first distance 2131 between the first tooth surface 1111 and the first side wall 2121 to be smaller than the second distance 2132 between the second tooth surface 1112 and the second side wall 2122, on the one hand, when the photovoltaic component 1 is under a positive pressure load of heavy snow, it can effectively resist the clockwise rotation of the photovoltaic component 1, and when the photovoltaic component 1 is under a negative pressure load of strong wind, it can effectively resist the counterclockwise rotation of the photovoltaic component 1, thereby improving the installation stability of the photovoltaic component 1; on the other hand, when the first tooth-shaped structure 111 contacts the second tooth-shaped structure 211, the horizontal component of the pressing force applied by the first pressing block 21 to the frame top plate 11 can be used to resist the rotation of the photovoltaic component 1, and the vertical component of the pressing force is applied to the laminate 14, thereby avoiding excessive pressing force applied to the laminate 14 and crushing the glass.

[0082] The following two situations are combined to introduce in detail the specific force analysis of photovoltaic modules under heavy snow positive pressure load and strong wind negative pressure load.

[0083] Scenario 1:

[0084] like Figure 5 and Figure 6 As shown, when the photovoltaic assembly 1 is under a heavy snow positive pressure load, under the gravity of the snow on the photovoltaic assembly 1, the photovoltaic assembly 1 rotates clockwise relative to the first pressing block 21, thereby driving the frame top plate 11 to rotate clockwise. Since the first distance 2131 between the first tooth surface 1111 and the first side wall 2121 is small and the second distance 2132 between the second tooth surface 1112 and the second side wall 2122 in the first direction is large (as shown in FIG. Figure 3 As shown), the first toothed structure 111 can be brought into contact with the second toothed structure 211 more quickly (as shown in FIG. Figure 6 In the embodiment, the first tooth surface 1111 contacts the first side wall 2121 as quickly as possible). After the first tooth-shaped structure 111 contacts the second tooth-shaped structure 211, the second tooth-shaped structure 211 applies a force F1 to the first tooth-shaped structure 111. The force F1 can be decomposed into a component force F1x parallel to the horizontal direction and a component force F1y parallel to the vertical direction. The force F1x is opposite to the force direction of the photovoltaic component 1 that causes the photovoltaic component 1 to rotate clockwise relative to the first pressing block 21, that is, F1x can offset the force that causes the photovoltaic component 1 to rotate clockwise relative to the first pressing block 21, thereby effectively resisting the clockwise rotation of the photovoltaic component 1. At the same time, when the photovoltaic component 1 rotates clockwise, the frame side plate 13 can abut against the connecting member 24 (such as Figure 5 As shown), the force applied by the connecting member 24 to the frame side plate 13 can also resist the clockwise rotation of the photovoltaic component 1, thereby improving the installation stability of the photovoltaic component 1 under the positive pressure load of heavy snow.

[0085] Scenario 2:

[0086] like Figure 7 and Figure 8 As shown, when the photovoltaic assembly 1 is under a strong wind negative pressure load, the photovoltaic assembly 1 rotates counterclockwise relative to the first pressing block 21, thereby driving the frame top plate 11 to rotate counterclockwise. Since 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, the first tooth structure 111 and the second tooth structure 211 are in contact (such as Figure 8 In the embodiment, the second tooth surface 1112 is in contact with the second side wall 2122), when the first tooth-shaped structure 111 abuts against the second tooth-shaped structure 211, the second tooth-shaped structure 211 applies a force F2 to the first tooth-shaped structure 111, and 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, and F2x is opposite to the force causing the photovoltaic component 1 to rotate counterclockwise, that is, F2x and the force causing the photovoltaic component 1 to rotate counterclockwise relative to the first pressing block 21 cancel each other out, thereby effectively preventing the photovoltaic component 1 from rotating counterclockwise under the condition of strong wind negative pressure load.

[0087] Preferably, if Figure 3 As shown, the central axis of the first side wall 2121 and the second side wall 2122 is a, and the central axis of the first tooth surface 1111 and the second tooth surface 1112 is b, wherein the angle α between a and b ranges from 5° to 20°.

[0088] Through such an arrangement, the angle α between a and b is controlled within the range of 5°-20°, so that the first distance 2131 between the first tooth surface 1111 and the first side wall 2121 in the first direction and the second distance 2132 between the second tooth surface 1112 and the second side wall 2122 in the first direction are both controlled within a preferred range, thereby avoiding the problem of poor abutment stability due to the small contact area between the first tooth surface 1111 and the first side wall 2121 when the first tooth-shaped structure 111 and the second tooth-shaped structure 211 come into contact due to the excessively large angle between a and b.

[0089] Preferably, if Figure 3 As shown, the angle β between the second tooth surface 1112 and the second direction is in the range of 10°-30°.

[0090] Through such a setting, on the one hand, when the photovoltaic component 1 is under a heavy snow positive pressure load, when the first toothed structure 111 contacts the second toothed structure 211, the contact area between the first toothed structure 111 (first tooth surface 1111) and the second toothed structure 211 can be made larger, which helps to improve the abutment stability between the first toothed structure 111 and the second toothed structure 211 and prevent the first toothed structure 111 from escaping from the second toothed structure 211; on the other hand, setting β in the range of 10°-30° can also facilitate improving the coordination effect between the first toothed structure 111 and the second toothed structure 211 and prevent the component frame from being unable to rotate due to the small angle.

[0091] Preferably, if Figure 6 As shown, the included angle between the first side wall 2121 and the second direction is γ1, wherein γ1<45°.

[0092] Specifically, Figure 5 and Figure 6 As shown, under the condition of heavy snow positive pressure load, 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, and the angle between F1 and its component force F1y in the vertical direction is θ1. Since F1 is perpendicular to the first side wall 2121, θ1+γ1=90°. When γ1<45°, θ1>45°, then F1x>F1y, which can ensure that the vertical component F1y of the clamping force F applied by the second toothed structure 211 to the first toothed structure 111 is smaller than its horizontal component F1x. In this way, the larger component F1x can be used to resist the clockwise rotation of the photovoltaic component 1, while the smaller component F1y is applied to the laminate 14. This can not only effectively resist the clockwise rotation of the photovoltaic component 1, but also effectively prevent the component frame from pressing the glass to cause the glass to shatter.

[0093] Preferably, the included angle between the second side wall 2122 and the second direction is γ2, wherein γ2<45°.

[0094] Specifically, Figure 7 and Figure 8As shown, under the condition of strong wind negative pressure load, the photovoltaic module 1 rotates counterclockwise relative to the first pressing block 21. When the first toothed structure 111 abuts against the second toothed structure 211, the second toothed structure 211 applies a pressing force F2 to the first toothed structure 111. The angle between F2 and its component force F2y in the vertical direction is θ2. Since F2 is perpendicular to the second side wall 2122, θ2+γ2=90°. When γ2<45°, θ2>45°, then F2 x>F2y, which means that the vertical component F2y of the pressing force applied by the second toothed structure 211 to the first toothed structure 111 is smaller than the horizontal component F2x. In this way, the larger component F2x can be used to resist the counterclockwise rotation of the photovoltaic component 1, while the smaller component F2y acts on the laminate 14. This can effectively resist the counterclockwise rotation of the photovoltaic component 1 and effectively prevent the component frame from pressing the glass to cause it to break.

[0095] Preferably, if Figure 3 As shown, the width w1 of the first tooth-shaped structure 111 at one end close to the frame top plate 11 is 0.8 mm-3 mm.

[0096] Through such a setting, it is possible to avoid the structural strength of the first tooth-shaped structure 111 being too low due to the width of the end of the first tooth-shaped structure 111 close to the frame top plate 11 being too small. At the same time, it is also possible to avoid the number of first tooth-shaped structures 111 that can be arranged on the frame top plate 11 being too small due to the width of the end of the first tooth-shaped structure 111 close to the frame top plate 11 being too large, thereby making it impossible for the first tooth-shaped structure 111 and the second tooth-shaped structure 211 to achieve a good coordination effect. It is also possible to avoid the processing difficulty of the component frame being increased due to the width of the end of the first tooth-shaped structure 111 close to the frame top plate 11 being too small.

[0097] Preferably, the width of the tip of the first tooth-shaped structure 111 is 0.15 mm-0.5 mm.

[0098] By setting the tip width of the first toothed structure 111 to 0.15 mm-0.5 mm, it is possible to avoid deformation and failure of the first toothed structure 111 when subjected to a large load due to the tip size of the first toothed structure 111 being too small, thereby ensuring the structural strength of the first toothed structure 111.

[0099] It should be noted that the present invention does not impose any limitation on the specific shape of the tip of the first tooth-shaped structure 111 .

[0100] In a specific embodiment, Figure 3 As shown, the tip of the first tooth-shaped structure 111 is an arc-shaped surface.

[0101] In another specific embodiment, the tip of the first tooth-shaped structure 111 is a plane (not shown in the figure).

[0102] Preferably, the tip of the first tooth-shaped structure 111 is an arc-shaped surface, wherein the radius of the arc-shaped surface is 0.1 mm-1 mm.

[0103] By setting the tip of the first tooth-shaped structure 111 to an arc-shaped surface, when the first tooth-shaped structure 111 contacts the second tooth-shaped structure 211, it helps to increase the contact area between the tip of the first tooth-shaped structure 111 and the second tooth-shaped structure 211. At the same time, setting the radius of the arc-shaped surface to 0.1mm-1mm can avoid the chamfer radius being too small, which will lead to the tip of the first tooth-shaped structure 111 being too weak. At the same time, it can also avoid the chamfer radius being too small, which will increase the difficulty of processing the component frame.

[0104] It should be noted that, in actual applications, those skilled in the art may set the gap 112 to increase gradually along the first direction from one end close to the frame side panel 13 to one end away from the frame side panel 13, or may set the frame top panel to have a first area and a second area distributed along the first direction, wherein the gap between the tip of the first tooth-shaped structure 111 in the second area and the inner wall of the groove 212 in the second direction is greater than the gap between the tip of the first tooth-shaped structure 111 in the first area and the inner wall of the groove 212 in the second direction, and so on. Such adjustments and changes to the specific setting method of gradually increasing the gap 112 along the first direction from one end close to the frame side panel 13 to one end away from the frame side panel 13 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0105] Preferably, if Figure 4 As shown, the frame top plate 11 has a first area 1121 and a second area 1122 distributed in sequence along the first direction, wherein the thickness D1 of the frame top plate 11 in the first area 1121 in the second direction is greater than the thickness D2 of the frame top plate 11 in the second area 1122, and the gap H1 between the tip of the first tooth-shaped structure 111 in the first area 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-shaped structure 111 in the second area 1122 and the inner wall of the groove 212 in the second direction.

[0106] By such an arrangement, when the photovoltaic component 1 is in strong wind or heavy snow weather and causes the component frame to rotate relative to the first pressing block 21, since the gap H1 in the first area 1121 is smaller than the gap H2 in the second area 1122, when the first tooth-shaped structure 111 contacts the second tooth-shaped structure 211, the first tooth-shaped structure 111 in the first area 1121 can preferentially contact the second tooth-shaped structure 211 and abut against the second tooth-shaped structure 211, so that the first tooth-shaped structure 111 in the second area 1122 contacts the second tooth-shaped structure 211 later, or the first tooth-shaped structure 111 in the second area 1122 can contact the second tooth-shaped structure 211 later. 1 does not contact the second tooth-shaped structure 211 (when the load is small), so that the force applied by the first pressing block 21 to the photovoltaic module 1 is more concentrated in the first area 1121 (that is, the end close to the frame side plate 13), which can more effectively avoid the pressing force applied by the first pressing block 21 from crushing the glass. At the same time, since the thickness of the frame top plate 11 in the first area 1121 is greater than the thickness of the frame top plate 11 in the second area 1122, the force applied by the first pressing block 21 to the frame top plate 11 is concentrated in the area with a larger thickness of the frame top plate 11 (that is, the first area 1121), which can effectively resist the deformation of the frame top plate 11.

[0107] It should be noted that if Figure 6 As shown, when the photovoltaic module 1 is in extreme snowy weather, under the action of the gravity of the accumulated snow, the first tooth-shaped structure 111 in the second area 1122 will first detach from the second tooth-shaped structure 211, and the first tooth-shaped structure 111 in the first area 1121 will detach from the second tooth-shaped structure 211 later. This can provide maintenance personnel with a certain amount of time for emergency repairs, avoiding that all the first tooth-shaped structures 111 are detached from the second tooth-shaped structure 211 at the same time, causing the photovoltaic module 1 to fall off, and further improving the installation stability of the photovoltaic module 1.

[0108] It should also be noted that the present invention does not impose any limitation on the specific number of the first tooth-shaped structure 111 and the second tooth-shaped structure 211. For example, the number of the first tooth-shaped structure 111 can be set to three, four, five, six or more, and the second tooth-shaped structure 211 can be set in a one-to-one correspondence with the first tooth-shaped structure 111, etc. Such adjustment and change of the specific number of the first tooth-shaped structure 111 and the second tooth-shaped structure 211 does not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0109] After multiple verifications, such as Figure 4 As shown, when the number of the first tooth-shaped structures 111 in the first area 1121 is three and the number of the first tooth-shaped structures 111 in the second area 1122 is three, the cooperation effect between the pressing block assembly 2 and the photovoltaic assembly 1 is optimal, and the processing difficulty of the pressing block assembly 2 and the assembly frame is lower.

[0110] Preferably, if Fig.10 As shown, the side of the frame top plate 11 away from the first tooth-shaped structure 111 has a contact portion 113, wherein the contact portion 113 abuts against the laminate 14 of the photovoltaic module 1, and the first tooth-shaped structure 111 on the side away from the frame side plate 13 is located above the contact portion 113 and the line PQ between the vertex P of the first tooth-shaped structure 111 and the midpoint Q of the contact portion 113 is perpendicular to the laminate 14.

[0111] Through such a configuration, when the first pressing block 21 is pressed on the frame top plate 11, 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 force uniformity at various positions on the contact portion 113 and avoiding the laminate 14 from being crushed due to uneven force on the contact portion 113.

[0112] It should be noted that, during actual installation, a person skilled in the art may set a pressing block assembly 2 on each side of the photovoltaic assembly 1 to fix the photovoltaic assembly 1 on the flexible bracket 3, or may set two pressing block assemblies 2 on each side of the photovoltaic assembly 1 to fix the photovoltaic assembly 1 on the flexible bracket 3, or may set multiple pressing block assemblies 2 on each side of the photovoltaic assembly 1 to fix the photovoltaic assembly 1 on the flexible bracket 3, and so on. Such adjustment and change to the specific setting quantity of the pressing block assembly 2 on the photovoltaic assembly 1 does not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0113] like Fig.18 As shown, two pressing block assemblies 2 are respectively arranged on both sides of the photovoltaic assembly 1 , wherein the pressing block assembly 2 located on one side of the photovoltaic assembly 1 is arranged correspondingly to the pressing block assembly 2 located on the other side of the photovoltaic assembly 1 .

[0114] After the installation is completed, the photovoltaic component 1 will vibrate under the action of wind, and the magnitude and direction of the wind force at different positions on the photovoltaic component 1 are not exactly the same, resulting in different vibration amplitudes at the positions corresponding to each pressing block assembly 2 on the photovoltaic component 1. If the first pressing block 21 has a certain elasticity, it can balance the deviation of the vibration amplitude at different positions of the photovoltaic component 1 and improve the installation stability.

[0115] It should be noted that the elasticity of the first pressing block 21 can be changed by changing the specific structure of the connecting member 24 .

[0116] The specific embodiments of the connecting member 24 of the present invention are described in detail below in combination with the following embodiments.

[0117] Embodiment 1:

[0118] like Figure 2 , Figure 5 and Figure 7 As shown, the connecting member 24 includes a first extending arm 241 extending along a first direction and a second extending arm 242 extending along a second direction. The second extending arm 242 is connected to the first pressing block 21 and is disposed opposite to the frame side plate 13 .

[0119] By setting the first extension arm 241, at least a portion of the connecting member 24 can be extended along the first direction, so that the first pressing block 21 has a certain elasticity. On the one hand, during installation, it is convenient to use the elasticity of the first pressing block 21 to make the component frame clamped between the first pressing block 21 and the second pressing block 22, thereby reducing the difficulty of installation and helping to improve the installation efficiency. On the other hand, since each photovoltaic component 1 needs to be installed on the flexible bracket 3 with multiple pressing block assemblies 2, but the size and direction of the wind force at different positions on the photovoltaic component 1 are not exactly the same, the first pressing block 21 has a certain elasticity and can also balance the deviation of the vibration amplitude at different positions of the photovoltaic component 1, thereby improving the installation stability.

[0120] At the same time, the first pressing block 21 is elastic and can also make the first tooth-shaped structure 111 away from the end of the frame side panel 13 disengage from the corresponding second tooth-shaped structure 211 when the component frame is subjected to a large force under the condition of heavy snow positive pressure load, thereby avoiding excessive force causing the glass to break.

[0121] Embodiment 2:

[0122] like Fig. 9 As shown, the connecting member 24 includes a first extension arm 241 extending along a first direction and a second extension arm 242 extending along a second direction, the second extension arm 242 is connected to the first pressing block 21 and the second extension arm 242 is arranged opposite to the frame side plate 13, and the pressing block assembly 2 also includes a fixing member 26, which is used to fix the first extension arm 241 on the second pressing block 22.

[0123] By providing the fixing member 26, when the photovoltaic module 1 is installed in an area with a relatively high wind speed, the first extension arm 241 can be fixed on the second pressing block 22, thereby reducing the elasticity of the first pressing block 21 and the vibration amplitude of the photovoltaic module 1, so that the first pressing block 21 is pressed tightly on the top of the module frame, and the auxiliary frame bottom plate 12 shares the load, avoiding excessive force on the frame bottom plate 12 and causing tearing, thereby facilitating the flexible adjustment of the elasticity of the first pressing block 21 according to the actual installation situation.

[0124] Exemplarily, when the photovoltaic module is installed in an area with a wind speed of level 6 (13.8 m / s) or below, the elasticity of the first pressing block 21 is increased, and a gap 112 is provided between all the first toothed structures 111 and the inner wall of the groove 212 in the second direction, that is, the first pressing block 21 is not in contact with the frame top plate 11, and only the frame bottom plate 12 bears the load.

[0125] When the photovoltaic module is installed in an area where the wind speed exceeds level 6 (13.8m / s wind speed), the first extension arm 241 can be fixed to the second pressing block 22 by the fixing member 26 to reduce the elasticity of the first pressing block 21, so that the first toothed structure 111 and the second toothed structure 211 at one end close to the frame side plate 13 are in contact with each other, and only the first toothed structure 111 at the end away from the frame side plate 13 and the inner wall of the groove 212 have a gap 112, that is, the first pressing block 21 is in contact with the frame top plate 11, and the auxiliary frame bottom plate 12 jointly bears the load to avoid tearing of the frame bottom plate 12.

[0126] Embodiment 3:

[0127] like Fig.11 As shown, the connecting member 24 only includes a second extending arm extending along the second direction, the second extending arm is connected to the first pressing block 21 and the second extending arm is arranged opposite to the frame side plate 13 .

[0128] In this case, the elasticity of the first pressing block 21 is relatively weak and the first pressing block 21 can reduce the vibration amplitude of the photovoltaic assembly 1, and is suitable for installation and use in areas with relatively high wind speeds.

[0129] It should be noted that although the present invention introduces the connecting member 24 of the present invention with the above three embodiments, this is not restrictive. Any other structural form that can connect the first pressure block 21 and the second pressure block 22 does not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0130] It should also be noted that, in actual applications, those skilled in the art may set the connecting member 24 so that the cross-sectional thickness is equal at all locations, or may set the connecting member 24 so that the cross-sectional thickness 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 in the protection scope of the present invention.

[0131] Preferably, if Figure 2 , Figure 5 and Fig. 9 As shown, 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 the extending direction thereof.

[0132] Through such an arrangement, the elasticity of the first pressing block 21 can be further increased, so that the deviation of the vibration amplitude at different positions of the photovoltaic component 1 can be better balanced, and the installation stability can be further improved.
