Description

Technical Field

[0001] This application relates to the field of photovoltaic module technology, and in particular to photovoltaic color steel tile structures and their fixing components. Background Technology

[0002] With advancements in photovoltaic (PV) power generation technology and continuously decreasing costs, an increasing number of industrial and residential buildings are deploying PV power generation devices on roofs, walls, and exterior facades. In construction projects, lightweight, high-strength PV corrugated steel sheets, which are easy to structurally process according to design requirements, serve as an effective carrier for fixing PV modules.

[0003] However, in coastal areas, frequent severe convective events and extreme weather conditions necessitate improvements in the wind resistance of photovoltaic (PV) corrugated steel roofing systems. As a crucial component of industrial buildings, the wind resistance of PV corrugated steel roofing systems directly impacts the overall stability and safety of the building. In densely built-up coastal cities, insufficient wind resistance during extreme weather events can easily lead to roof tearing and debris scattering, causing incalculable losses of life and property.

[0004] In the existing technology, photovoltaic color steel tiles are supported by fasteners installed on the mounting surface, and the structure of the fasteners is designed to snap the protruding parts of the photovoltaic color steel tiles. However, this structure is a rigid connection when facing strong winds or thermal expansion and contraction, without any movable allowance, which can easily cause damage to the roof photovoltaic color steel tiles. Utility Model Content

[0005] Based on this, it is necessary to address the problem that existing technologies support photovoltaic color steel tiles by using fasteners installed on the mounting surface, and that the fasteners are designed to snap the protruding parts of the photovoltaic color steel tiles. However, this structure is rigidly connected and lacks any movable allowance when facing strong winds or thermal expansion and contraction, which can easily cause damage to the roof photovoltaic color steel tiles. Therefore, a photovoltaic color steel tile structure and its fixing components should be provided.

[0006] A photovoltaic color steel tile fixing component is used to fix photovoltaic color steel tiles. The photovoltaic color steel tile fixing component includes: a mounting base placed on the bottom side of the photovoltaic color steel tile and fixed to the mounting surface, a pressure plate placed on the upper part of the photovoltaic color steel tile, and fasteners.

[0007] The fastener passes through the pressure plate, the photovoltaic corrugated steel tile, and the mounting base, connecting the pressure plate and the photovoltaic corrugated steel tile to the mounting base.

[0008] The fastener is fixed to the photovoltaic color steel tile or the mounting base. The mounting base or the photovoltaic color steel tile is provided with a strip hole along a first direction corresponding to the fastener. The fastener can move in the strip hole along the first direction, which is the extension direction of the protrusion of the photovoltaic color steel tile.

[0009] In the specific installation and fixing process of the aforementioned photovoltaic color steel tile fixing assembly, the pressure plate, photovoltaic color steel tile, and mounting base are stacked in sequence. Then, the fasteners are matched with the strip holes so that the fasteners can move in the first direction within the strip holes. This allows the photovoltaic color steel tile to have space to move in the first direction relative to the mounting base fixed to the mounting surface. This enables the photovoltaic color steel tile to move slightly in the first direction when facing extreme weather such as strong winds or excessive cold or heat, releasing the internal stress of the photovoltaic color steel tile caused by the external environment and improving the strength of the photovoltaic color steel tile against extreme weather.

[0010] In one embodiment, the fastener passes through the photovoltaic corrugated steel sheet and is fixed relative to the position of the photovoltaic corrugated steel sheet;

[0011] The pressure plate has a first strip-shaped hole, and the mounting base has a second strip-shaped hole. The first strip-shaped hole and the second strip-shaped hole both extend along a first direction and are positioned correspondingly.

[0012] One end of the fastener is movable in the first direction within the first slot, and the other end is movable in the first direction within the second slot.

[0013] In one embodiment, the fastener passes through the photovoltaic color steel tile, with one end for connecting to the pressure plate and the other end for connecting to the mounting base;

[0014] The photovoltaic color steel tile has a strip-shaped hole along a first direction, and the fastener passes through the strip-shaped hole and can move within the strip-shaped hole along the first direction.

[0015] In one embodiment, the pressure plate has a first strip-shaped hole, and the photovoltaic color steel tile has a second strip-shaped hole. The first strip-shaped hole and the second strip-shaped hole both extend along a first direction and are positioned correspondingly.

[0016] One end of the fastener is connected to the mounting base, and the other end passes through the second strip hole and the first strip hole in sequence. The fastener is able to move in the first direction within the first strip hole and the second strip hole.

[0017] In one embodiment, the photovoltaic color steel tile fixing assembly includes two sets of fasteners;

[0018] The mounting base includes a base, two mounting arms, and two limiting arms. The base is connected to the mounting surface. One end of each mounting arm is connected to the base, and the other end is connected to the limiting arm. The two mounting arms are spaced apart along a second direction, and the two limiting arms are located on the side where the two mounting arms are close to each other. The protrusion of the photovoltaic color steel tile can pass through the space between the two limiting arms and enter the mating space formed by the two mounting arms.

[0019] The pressure plate includes a cover plate and two connecting plates. The two connecting plates are respectively connected to both ends of the cover plate along the second direction. The cover plate portion is located within the limiting space formed by the protrusion. The limiting space and the cover plate portion form a limiting fit. The positions of the two connecting plates correspond one-to-one with the two mounting arms. Photovoltaic color steel tiles are clamped between the connecting plates and the mounting arms, and between the cover plate and the limiting arms.

[0020] The two sets of fasteners correspond one-to-one with the two connecting plates and the two mounting arms. The fasteners pass through the connecting plates, the photovoltaic color steel tiles, and the mounting arms, connecting the connecting plates and the photovoltaic color steel tiles to the mounting arms.

[0021] In one embodiment, the photovoltaic color steel tile fixing assembly further includes a protective member, which is disposed on the side of the pressure plate opposite to the photovoltaic color steel tile and covers the first strip hole.

[0022] In one embodiment, the protective member includes two connectors and a cover. The two connectors are respectively connected to the edges of both ends of the cover. The two connectors are respectively located on both sides of the extension direction of the first strip hole and connected to the connecting plate. The cover covers the first strip hole.

[0023] In one embodiment, the connecting plate is provided with two strip-shaped protrusions, which are respectively located on both sides of the extension direction of the first strip-shaped hole. The two connecting members are respectively located on opposite sides of the two strip-shaped protrusions, and the connecting members slide in cooperation with the strip-shaped protrusions along the first direction.

[0024] In one embodiment, grooves are respectively provided on opposite sides of the two strip-shaped protrusions, the grooves extending along the first direction, and a protrusion is provided on the side of the connector near the first strip-shaped hole, the protrusion being partially located within the groove, so that the connector and the strip-shaped protrusion slide in cooperation along the first direction.

[0025] In one embodiment, the strip protrusion gradually increases in thickness along the direction opposite to the cover, in the direction in which the two connectors are arranged.

[0026] In one embodiment, the protective member further includes two sealing plates, which are respectively connected to both ends of the cover member along the first direction to form a cavity with the cover member that opens toward the pressure plate.

[0027] In one embodiment, the cover plate includes two cover plates and a protruding plate. The two ends of the protruding plate along the second direction are respectively connected to the two cover plates. The end of the cover plate opposite to the protruding plate is connected to the connecting plate. The protruding plate passes between the two limiting arms and is at least partially attached to the protrusion of the photovoltaic color steel tile. The maximum distance of the protruding plate along the second direction is greater than the distance between the two limiting arms.

[0028] In one embodiment, the distance between the two mounting arms gradually increases along a third direction toward the base, where the third direction is the height direction of the base.

[0029] One embodiment of this application also provides a photovoltaic color steel tile structure, the photovoltaic color steel tile structure comprising: a photovoltaic color steel tile and a plurality of the photovoltaic color steel tile fixing components;

[0030] The photovoltaic color steel tile has a protrusion extending along the first direction. The protrusion passes between the two limiting arms and is engaged between the two mounting arms. The photovoltaic color steel tile is located between the mounting base and the pressure plate. The mounting arm and the photovoltaic color steel tile abut against each other. The pressure plate abuts against the side of the photovoltaic color steel tile away from the mounting arm.

[0031] During the installation and fixing process of the aforementioned photovoltaic color steel tile fixing assembly, the base is first connected to the mounting surface. Then, the protruding part of the photovoltaic color steel tile is passed between the two limiting arms, positioning the protruding part between the two mounting arms. Next, a cover plate is placed over the side of the photovoltaic color steel tile facing away from the base, and fasteners are inserted through the first and second slotted holes and the photovoltaic color steel tile itself to fix the photovoltaic color steel tile to the fixing assembly. The photovoltaic color steel tile can be pre-drilled. Preferably, because the photovoltaic color steel tile is relatively thin, holes can be drilled after covering the base using self-tapping screws or a drill bit. Simultaneously, the first and second slotted holes allow fasteners to pass through. Furthermore, both the first and second strip holes extend along the first direction and correspond to each other. Therefore, the cover plate can be placed on the side of the photovoltaic color steel tile away from the base. Then, the self-tapping screws are inserted into the first strip hole to abut against the photovoltaic color steel tile. Subsequently, self-tapping holes are drilled to allow the fasteners to pass through the first strip hole, the second strip hole, and the photovoltaic color steel tile. At the same time, the fasteners and the photovoltaic color steel tile are tightly fitted together, and the photovoltaic color steel tile is fixed to the installation surface by the fixing components to await the installation position. In the event of strong winds or extreme weather such as excessive cold or heat, sufficient space can be provided for the photovoltaic color steel tile to move, thereby releasing the internal stress of the photovoltaic color steel tile caused by the external environment and improving the strength of the photovoltaic color steel tile against extreme weather.

[0055] See Figure 1 , Figure 1 This illustration shows a schematic diagram of a photovoltaic color steel tile fixing assembly 100 installing a photovoltaic color steel tile 210 at a desired installation position according to an embodiment of this application. The photovoltaic color steel tile fixing assembly 100 provided in this embodiment is used to fix the photovoltaic color steel tile 210, which is used to install photovoltaic modules.

[0056] The photovoltaic color steel tile fixing component 100 includes: a mounting base 110 placed on the bottom side of the photovoltaic color steel tile 210 and fixed to the mounting surface, a pressure plate 130 placed on the upper part of the photovoltaic color steel tile 210, and fasteners 120.

[0057] In the aforementioned photovoltaic color steel tile fixing assembly 100, the fastener 120 passes through the pressure plate 130, the photovoltaic color steel tile 210, and the mounting base 110, connecting the pressure plate 130 and the photovoltaic color steel tile 210 to the mounting base 110. The fastener 120 is fixed to the photovoltaic color steel tile 210 or the mounting base 110. The mounting base 110 or the photovoltaic color steel tile 210 is provided with a strip hole along the first direction OY at the location corresponding to the fastener 120. The fastener 120 can move in the strip hole along the first direction OY, where the first direction OY is the extension direction of the protrusion 211 of the photovoltaic color steel tile 210.

[0058] In the specific installation and fixing process of the aforementioned photovoltaic color steel tile fixing component 100, the pressure plate 130, photovoltaic color steel tile 210, and mounting base 110 are stacked in sequence. Then, the fastener 120 is engaged with the strip hole so that the fastener 120 can move along the first direction OY within the strip hole. This allows the photovoltaic color steel tile 210 to have space to move along the first direction OY relative to the mounting base 110 fixed on the mounting surface. This allows the photovoltaic color steel tile 210 to move slightly along the first direction OY when facing extreme weather such as strong winds or excessive cold or heat, releasing the internal stress of the photovoltaic color steel tile 210 caused by the external environment and improving the strength of the photovoltaic color steel tile 210 against extreme weather.

[0059] The process of fastener 120 engaging with the slotted hole includes the following three embodiments:

[0060] In one embodiment, the fastener 120 passes through the photovoltaic corrugated steel sheet 210 and is fixed relative to the position of the photovoltaic corrugated steel sheet 210; the pressure plate 130 has a first strip-shaped hole 133, and the mounting base 110 has a second strip-shaped hole 114. The first strip-shaped hole 133 and the second strip-shaped hole 114 both extend along the first direction OY and are positioned correspondingly; one end of the fastener 120 can move along the first direction OY in the first strip-shaped hole 133, and the other end can move along the first direction OY in the second strip-shaped hole 114. In this embodiment, the photovoltaic corrugated steel sheet 210... The fastener 120 can be pre-drilled and passed through the opening in the photovoltaic color steel tile 210 to fix the fastener 120 relative to the photovoltaic color steel tile 210. Alternatively, an automatic screw or drill bit can be used to drill a hole in the photovoltaic color steel tile 210 through the first strip hole 133 after the pressure plate 130, photovoltaic color steel tile 210, and mounting base 110 are stacked, so that the fastener 120 passes through the first strip hole 133, the photovoltaic color steel tile 210, and the second strip hole 114, thereby fixing it relative to the photovoltaic color steel tile 210 and ensuring that the photovoltaic color steel tile 210 can move relative to the mounting base 110.

[0061] In another embodiment, a fastener 120 passes through the photovoltaic color steel tile 210, with one end for connection to the pressure plate 130 and the other end for connection to the mounting base 110. The photovoltaic color steel tile 210 has a strip-shaped hole along the first direction OY. The fastener 120 passes through the strip-shaped hole and can move within the strip-shaped hole along the first direction OY. In this embodiment, the fastener 120, which is fixed relative to the pressure plate 130 and the mounting base 110, moves relative to the photovoltaic color steel tile 210 along the first direction OY within the strip-shaped hole on the photovoltaic color steel tile 210, so that the photovoltaic color steel tile 210 can move relative to the mounting base 110 fixed to the mounting surface along the first direction OY.

[0062] In another embodiment, the pressure plate 130 has a first strip hole 133, and the photovoltaic color steel tile 210 has a second strip hole 114. The first strip hole 133 and the second strip hole 114 both extend along the first direction OY and are positioned correspondingly. One end of the fastener 120 is connected to the mounting base 110, and the other end passes through the second strip hole 114 and the first strip hole 133 in sequence. The fastener 120 can move along the first direction OY within the first strip hole 133 and the second strip hole 114, so that the pressure plate 130 and the photovoltaic color steel tile 210 can be relatively fixed to the mounting base 110 on the mounting surface and move along the first direction OY. The movement is limited by the cooperation of the fastener 120 with the first strip hole 133 and the second strip hole 114, thereby ensuring that the photovoltaic color steel tile 210 can be relatively fixed to the mounting base 110 on the mounting surface and move along the first direction OY.

[0063] In one embodiment, the photovoltaic color steel tile fixing assembly 100 includes two sets of fasteners, the mounting base 110 includes a base 111, two mounting arms 112 and two limiting arms 113, and the pressure plate 130 includes a cover plate 131 and two connecting plates 132.

[0064] See Figure 1 , Figure 5 as well as Figure 7 In the aforementioned photovoltaic color steel tile fixing assembly 100, the base 111 is connected to the mounting surface, one end of the mounting arm 112 is connected to the base 111, and the other end is connected to the limiting arm 113. Two mounting arms 112 are spaced apart along the second direction OX, and two limiting arms 113 are located on the side where the two mounting arms 112 are close to each other. The protrusion 211 of the photovoltaic color steel tile 210 can pass through the space between the two limiting arms 113 and enter the mating space formed by the two mounting arms 112. Two connecting plates 132 are respectively connected to both ends of the cover plate 131 along the second direction OX. Part of the cover plate 131 is located within the limiting space formed by the protrusion 211, and the limiting space and part of the cover plate 131 form a limiting fit. The positions of the two connecting plates 132 correspond one-to-one with the two mounting arms 112. The space between the connecting plates and the mounting arms 112, and between the cover plate 131 and the limiting arms 113, are used to clamp the photovoltaic color steel tile 210. Two sets of fasteners 120 correspond one-to-one with two connecting plates 132 and two mounting arms 112 respectively. The fasteners 120 pass through the connecting plates 132, photovoltaic color steel tiles 210, and mounting arms 112, connecting the connecting plates 132 and photovoltaic color steel tiles 210 to the mounting arms 112. The fasteners 120 are fixed to the photovoltaic color steel tiles 210 or the mounting arms 112. The mounting arms 112 or the photovoltaic color steel tiles 210 are provided with strip holes along the first direction OY at the corresponding fasteners 120. The fasteners 120 can move along the first direction OY in the strip holes. The second direction OX, the first direction OY, and the third direction OZ are perpendicular to each other.

[0065] refer to Figure 1 The maximum width of the protrusion 211 of the photovoltaic color steel tile 210 along the first direction OX is greater than the minimum distance between the two limiting arms 113. At the same time, the width of the protrusion 211 is the smallest between the two limiting arms 113, and the width is the largest near the base 111. Therefore, during installation, the two limiting arms 113 can be opened first, and the two mounting arms 112 can be elastically deformed to move away from each other. The part with the maximum width of the protrusion 211 can be placed into the mating space formed by the two mounting arms 112. Then, the two limiting arms 113 can be released to restore the original state. The part with the minimum width of the protrusion 211 is between the two limiting arms 113. If the part with the maximum width of the protrusion 211 wants to detach from the photovoltaic color steel tile fixing component 100, it will be blocked by the two limiting arms 113. Thus, the color steel tile 210 is stably fixed relative to the photovoltaic color steel tile fixing component 100 along the third direction OZ and the second direction OX. The third direction OZ is the height direction of the base 111. Furthermore, the cover plate 131 is located within the limiting space formed by the protrusion 211. This part of the cover plate also has a portion whose maximum width along the first direction is greater than the minimum distance between the two limiting arms 113, and a portion of its width can be locked between the two limiting arms 113. Therefore, it forms a portion with the same shape as the protrusion 211 to cooperate with the two limiting arms 113. After the protrusion is placed into the mating space formed by the two mounting arms 112, the widest part of the cover plate 131 is placed into the limiting space formed by the protrusion 211 in the same way. Then, after the fastener 120 passes through the connecting plate 132, the photovoltaic color steel tile 210, and the mounting arm 112, the photovoltaic color steel tile 210 is also limited in the first direction OY. This makes the photovoltaic color steel tile 210 limited in three directions. Only in the first direction OY is a certain amount of movement space provided for the photovoltaic color steel tile 210 through the first strip hole 133 to resist the force of the external environment and ensure the stability of the photovoltaic color steel tile 210.

[0066] Preferably, the connecting plate 132 has a first strip-shaped hole 133 along the first direction OY, and the mounting arm 112 has a second strip-shaped hole 114 along the first direction OY. Both the first strip-shaped hole 133 and the second strip-shaped hole 114 extend along the first direction OY and are positioned correspondingly. The fastener 120 is used to pass through the photovoltaic color steel tile 210, and one end of the fastener 120 is movably inserted through the first strip-shaped hole 133 along the first direction OY, and the other end is movably inserted through the second strip-shaped hole 114 along the first direction OY. Figure 3 and Figure 4 .

[0067] During the installation and fixing process of the aforementioned photovoltaic color steel tile fixing assembly 100, the base 111 is first connected to the mounting surface. Then, the protrusion 211 of the photovoltaic color steel tile 210 is passed between the two limiting arms 113, positioning the protrusion 211 between the two mounting arms 112. Next, the cover plate 131 is placed over the side of the photovoltaic color steel tile 210 facing away from the base 111, and fasteners 120 are inserted through the first slot 133, the second slot 114, and the photovoltaic color steel tile 210 to fix the photovoltaic color steel tile 210 to the photovoltaic color steel tile fixing assembly 100. The photovoltaic color steel tile 210 can be pre-drilled. Preferably, since the photovoltaic color steel tile 210 is relatively thin, holes can be drilled after covering the base 111 using self-tapping screws or a drill bit. Simultaneously, since the first slot 133 and the second slot 114 allow the fasteners 120 to pass through, and the first slot 133 and the second slot 114... Both strip holes 114 extend along the first direction OY and correspond to each other, so the cover plate 131 can be placed on the side of the photovoltaic color steel tile 210 away from the base 111. Then, the self-tapping screws are inserted into the first strip hole 133 to abut against the photovoltaic color steel tile 210. Then, the self-tapping screws are drilled so that the fasteners 120 pass through the first strip hole 133, the second strip hole 114 and the photovoltaic color steel tile 210. At the same time, the fasteners 120 and the photovoltaic color steel tile 210 are tightly fitted, and the photovoltaic color steel tile 210 is connected to the installation surface by the fixing component to wait for the installation position. When encountering strong winds or extreme weather such as excessive cold or heat, the photovoltaic color steel tile 210 can move slightly along the first direction OY relative to the photovoltaic color steel tile fixing component 100, thereby providing sufficient movable space for the photovoltaic color steel tile 210, releasing the internal stress of the photovoltaic color steel tile 210 caused by the external environment, and improving the strength of the photovoltaic color steel tile 210 against extreme weather.

[0068] The photovoltaic module described above can also have fasteners 120 inserted through the photovoltaic color steel tile 210, with one end used to connect to the connecting plate 132 and the other end used to connect to the mounting arm 112; the photovoltaic color steel tile 210 has a strip hole along the first direction OY, and the fasteners 120 are inserted through the strip hole and can move along the first direction OY within the strip hole.

[0069] Alternatively, the connecting plate 132 may have a first strip hole 133, and the photovoltaic color steel tile 210 may have a second strip hole 114. Both the first strip hole 133 and the second strip hole 114 extend along the first direction OY and are positioned correspondingly. One end of the fastener 120 is connected to the mounting arm 112, and the other end passes through the second strip hole 114 and the first strip hole 133 in sequence. The fastener 120 can move along the first direction OY within the first strip hole 133 and the second strip hole 114, thereby allowing the pressure plate 130 and the photovoltaic color steel tile 210 to be relatively fixed to the mounting base 110 on the mounting surface and move along the first direction OY.

[0070] Specifically, both ends of the fastener are provided with limiting portions, which are larger than the width of the slot, to prevent the fastener from falling off along the direction in which the first slot is opened. The fastener can be a rivet, or a bolt and nut structure, which will not be elaborated here.

[0071] Specifically, the mounting arm 112 is configured as a wall protruding from the base 111, and the limiting arm 113 is configured as a barb structure at the end of the mounting arm 112. The distance between the end of the barb structure and the base 111 matches the connection point of the photovoltaic color steel tile 210 to be fixed and the protrusion 211, so as to allow the protrusion 211 of the photovoltaic color steel tile 210 to be fixed to engage with the barb structure.

[0072] Specifically, the base 111 has mounting holes 115, through which mounting components 121, such as screws or bolts, pass through the mounting holes 115 to fix the base 111 to the installation position.

[0073] See Figure 1 , Figure 7 as well as Figure 8 In one embodiment, the photovoltaic color steel tile fixing assembly 100 further includes a protective member 140. The protective member 140 is disposed on the side of the pressure plate 130 opposite to the photovoltaic color steel tile 210 and covers the first strip hole 133. By covering the first strip hole 133 with the protective member 140, rainwater is prevented from entering the connection between the photovoltaic color steel tile fixing assembly 100 and the photovoltaic color steel tile 210 and the installation position through the first strip hole 133, thereby protecting the photovoltaic color steel tile fixing assembly 100 and the photovoltaic color steel tile 210 and improving the service life of the photovoltaic color steel tile 210.

[0074] See Figure 1 , Figure 7 as well as Figure 8 In one embodiment, the protective member 140 includes two connectors 141 and a cover 142. The two connectors 141 are respectively connected to the edges of both ends of the cover 142. The two connectors 141 are respectively located on both sides of the extension direction of the first strip hole 133 and connected to the connecting plate 132. The cover 142 covers the first strip hole 133, thereby forming a gap between the cover 142 and the connecting plate 132 through the connectors 141, providing a receiving space for the head of the fastener 120, such as a screw head.

[0075] See Figure 1 , Figure 7 as well as Figure 8In one embodiment, the connecting plate 132 is provided with two strip-shaped protrusions 136, which are located on both sides of the extension direction of the first strip-shaped hole 133. Two connectors 141 are located on opposite sides of the two strip-shaped protrusions 136. The connectors 141 and the strip-shaped protrusions 136 slide in a first direction OY, thereby making the installation of the protective member 140 more convenient through the sliding engagement of the connectors 141 and the strip-shaped protrusions 136.

[0076] See Figure 4 and Figure 8 In one embodiment, two strip-shaped protrusions 136 are provided with grooves 137 on opposite sides. The grooves 137 extend along the first direction OY. A protrusion 144 is provided on the side of the connector 141 near the first strip-shaped hole 133. The protrusion 144 is partially located in the groove 137 so that the connector 141 and the strip-shaped protrusions 136 slide in the first direction OY. This allows the connector 141 to be limited in the direction perpendicular to the groove 137 by the protrusion 144 and the groove 137. At the same time, the sliding track of the sliding engagement is clear and the engagement is smoother. The groove 137 can also serve as a water guide, guiding rainwater along the groove 137 to the surface of the connecting plate 132, preventing rainwater from accumulating at the connection between the protective member 140 and the connecting plate 132 and corroding the components.

[0077] See Figure 4 and Figure 8 In one embodiment, along the direction away from the cover 142, the thickness of the strip protrusion 136 gradually increases along the arrangement direction of the two connectors 141, so that the distance between the two connectors 141 of the cover 142 is greater than the maximum distance between the two strip protrusions 136 away from the connecting plate 132, which makes it easier for the protrusion 144 to engage with the groove 137 when the two connectors 141 contact and slide with the two strip protrusions 136.

[0078] In one embodiment, the protective member 140 further includes two sealing plates 143, which are respectively connected to the two ends of the cover member 142 along the first direction OY, thereby preventing the protective member 140 from falling off the connecting plate 132. Specifically, the sealing plates and the cover member can form a cavity with an opening facing the pressure plate, so that the cover member 142 covers the first strip hole 133 through the opening. Specifically, the connection method can be that the connecting member 141 and the strip protrusion 136 are elastically snapped together along the arrangement direction of the two connecting members 141, or the connecting member 141 can be directly welded or bonded to the connecting plate 132.

[0079] See Figure 9In another embodiment, the protective component 140 further includes a sealing plate 143, which is selectively connected to both ends of the cover 142 along the first direction OY, thereby preventing the protective component 140 from falling off the connecting plate 132. At the same time, since the sealing plate 143 is only connected to one end of the cover 142 along the first direction OY, the cover 142 can be removed from the slide groove 137 from the other end, and the fasteners can be removed to replace the photovoltaic color steel tile 210.

[0080] Preferably, a limiting protrusion is provided on the inner wall of the slide groove 137 near the end of the sealing plate 143, so that the sealing plate 143 and the limiting protrusion respectively achieve limit limiting at both ends of the sliding direction of the protective member 140, which can prevent the protective member 140 from falling off during the cooperation with the connecting plate 132.

[0081] See Figure 3 and Figure 6 In one embodiment, the cover plate 131 includes two cover plates 134 and a protruding plate 135. The two ends of the protruding plate 135 along the second direction OX are respectively connected to the two cover plates 134. The end of the cover plate 134 facing away from the protruding plate 135 is connected to the connecting plate 132. The protruding plate 135 passes between the two limiting arms 113 and is at least partially attached to the protrusion 211 of the photovoltaic color steel tile 210. The maximum distance of the protruding plate 135 along the second direction OX is greater than the distance between the two limiting arms 113. In this embodiment, the maximum distance of the protrusion 211 of the photovoltaic color steel tile 210 along the second direction OX is less than the distance between the two mounting arms 112 but greater than the distance between the two limiting arms 113. Therefore, when installing the protrusion 211 of the photovoltaic color steel tile 210, the protrusion 211 can be placed between the two mounting arms 112 after passing through the two limiting arms 113, and the limiting arms 113 can be used to position the photovoltaic color steel tile 210 away from the base 111. The movement is limited, and at the same time, the cover plate 134 covers the planes on both sides of the protrusion 211 of the photovoltaic color steel tile 210. The protruding plate 135 passes between the two limiting arms 113 and is at least partially attached to the protrusion 211 of the photovoltaic color steel tile 210. The connecting plate 132 is attached to the connection structure of the protrusion 211 of the photovoltaic color steel tile 210 and the base 111. The fastener 120 passes through the first strip hole 133, the second strip hole 114, and the base 111. The photovoltaic color steel tile 210 is fixed to the pressure plate 130 by fasteners 120. At the same time, the convex plate 135 passing through the two limiting arms 113 and entering the two mounting arms 112 further limits the movement of the photovoltaic color steel tile 210 away from the base 111. Thus, the irregular structure of the photovoltaic color steel tile 210 is triple-limited by the two fasteners 120 and the convex plate 135, making the installation of the photovoltaic color steel tile 210 more stable.

[0082] See Figure 2In one embodiment, the distance between the two mounting arms 112 gradually widens along the third direction OZ towards the base 111, thereby making the mounting base 110 form a trapezoidal structure. Compared with the rectangular structure, it has a stronger supporting capacity and forms a resistance and support at the corresponding position on the bottom surface of the color steel tile. It has a stronger ability to resist deformation caused by extreme weather, making the installation and fixing of the photovoltaic color steel tile 210 more stable. The third direction OZ is the height direction of the base 111.

[0083] One embodiment of this application also provides a photovoltaic color steel tile structure, which includes: a photovoltaic color steel tile 210 and a plurality of photovoltaic color steel tile fixing components 100.

[0084] The photovoltaic color steel tile 210 has a protrusion 211 extending along the first direction OY. The protrusion 211 passes between two limiting arms 113 and is engaged between two mounting arms 112. The photovoltaic color steel tile 210 is located between the mounting base 110 and the pressure plate 130. The mounting arm 112 and the photovoltaic color steel tile 210 abut against each other. The pressure plate 130 abuts against the side of the photovoltaic color steel tile 210 away from the mounting arm 112. The photovoltaic color steel tile 210 has multiple protrusions 211. The multiple protrusions 211 are installed one-to-one on multiple photovoltaic color steel tile fixing components 100, so that the photovoltaic color steel tile 210 with a larger installation area can be installed through multiple photovoltaic color steel tile fixing components 100.

[0085] During the installation and fixing process of the aforementioned photovoltaic color steel tile fixing assembly 100, the base 111 is first connected to the mounting surface. Then, the protrusion 211 of the photovoltaic color steel tile 210 is passed between the two limiting arms 113, positioning the protrusion 211 between the two mounting arms 112. Next, the cover plate 131 is placed over the side of the photovoltaic color steel tile 210 facing away from the base 111, and fasteners 120 are inserted through the first slot 133, the second slot 114, and the photovoltaic color steel tile 210 to fix the photovoltaic color steel tile 210 to the photovoltaic color steel tile fixing assembly 100. The photovoltaic color steel tile 210 can be pre-drilled. Preferably, since the photovoltaic color steel tile 210 is relatively thin, holes can be drilled after covering the base 111 using self-tapping screws or a drill bit. Simultaneously, the first slot 133 and the second slot 114 provide fastening... The component 120 passes through, and the first strip hole 133 and the second strip hole 114 both extend along the first direction OY and correspond to each other. Therefore, the cover plate 131 can cover the side of the photovoltaic color steel tile 210 away from the base 111. Then, the self-tapping screw is abutted against the photovoltaic color steel tile 210 in the first strip hole 133. Then, the self-tapping hole is drilled so that the fastener 120 passes through the first strip hole 133, the second strip hole 114 and the photovoltaic color steel tile 210. At the same time, the fastener 120 and the photovoltaic color steel tile 210 are tightly fitted, and the photovoltaic color steel tile 210 is fixed to the installation surface by the fixing component and waits for the installation position. When encountering strong winds or extreme weather such as excessive cold or heat, it can provide sufficient space for the photovoltaic color steel tile 210 to move, thereby releasing the internal stress of the photovoltaic color steel tile 210 caused by the external environment and improving the strength of the photovoltaic color steel tile 210 against extreme weather.

[0086] The technical features of the above embodiments can be combined in any way.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
