[0058] The clamping member 21 is suitable for being arranged between the photovoltaic component and the purlin 3. The clamping member 21 has a clamping portion and a fixing portion. The clamping portion is used to clamp the frame bottom plate 111, and the fixing portion is used to cooperate with the purlin 3 so that the clamping member 21 abuts against the purlin 3. The pressing block is located above the clamping member 21 and is suitable for abutting and connecting with the component frame 11. The pressing block is located above the clamping member 21 and is suitable for abutting with the component frame 11. The locking member 23 is used to fix the pressing block on the purlin 3.

[0060] It should be noted that, in practical applications, those skilled in the art do not impose any limitation on the specific configuration type of the clamping member 21 , as long as it has a clamping portion and a fixing portion.

[0061] In a specific embodiment, Figures 14 to 16 As shown, the clamping member 21 includes a connecting plate 212 and a clamping plate 211 and a lap plate 213 connected to the connecting plate 212.

[0063] In another possible embodiment, the clamping member 21 includes two clamping arms arranged opposite to each other and a lap block (not shown in the figure) arranged at the bottom of the clamping arms. The frame bottom plate 111 can be clamped between the two clamping arms, and the purlin 3 is abutted against the lap block.

[0065] Through such a configuration, the structure of the clamping member 21 can be made simpler and the processing cost can be lowered. At the same time, the weight of the clamping member 21 can also be made lighter, thereby reducing the load weight of the photovoltaic module.

[0066] It should be noted that the present invention does not impose any limitation on the specific connection method between the connecting plate 212 and the clamping plate 211. For example, the connecting plate 212 and the clamping plate 211 can be arranged to be integrally formed, or the connecting plate 212 and the clamping plate 211 can be arranged to be welded or adhesively connected, or the connecting plate 212 and the clamping plate 211 can be arranged to be fixedly connected or snap-connected by fasteners, etc. Such adjustments and changes to the specific connection method between the connecting plate 212 and the clamping plate 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.

Of course, preferably, the fastener is configured to include a fastening bolt 2181 and a fastening nut 2182.

[0075] It should also be noted that the present invention does not impose any limitation on the specific structure of the pressing block. For example, the pressing block can be set as a middle pressing block, which is used between two adjacent photovoltaic modules. Alternatively, the pressing block can be set as an edge pressing block, and so on. Such adjustments and changes to the specific structure of the pressing block do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

When installed, the first limiting plate 2241 and the second limiting plate 2242 are respectively located in the limiting holes 216 of two adjacent clamping members 21 .

[0088] Preferably, the first limiting plate 2241 and the second limiting plate 2242 are both connected to the fixed plate 221.

[0090] For example, the width of the limiting plate 224 is smaller than the width of the limiting hole, and the length of the limiting plate 224 is smaller than the length of the limiting hole.

[0091] Embodiment 2:

[0092] like Figures 5 to 9 As shown, the pressing block assembly is arranged between two adjacent photovoltaic modules, and the module frame 11 also has a frame side panel 112. The pressing block includes a fixed plate 221, a first side pressing plate 2221 and a second side pressing plate 2222 connected to the fixed plate 221, and the first side pressing plate 2221 and the second side pressing plate 2222 are respectively located on both sides of the fixed plate 221. When installed, the side surfaces of the first side pressing plate 2221 and the second side pressing plate 2222 are respectively abutted against the frame side panels 112 of the two adjacent photovoltaic modules, and the locking member 23 is used to fix the fixed plate 221 on the purlin 3. The pressing block can also abut against the clamping plate 211 to press the clamping member 21 onto the purlin 3.

[0093] Through such an arrangement, when the locking member 23 fixes the pressing block on the purlin 3, the first side pressing plate 2221 and the second side pressing plate 2222 abut against the clamping plate 211, thereby pressing the clamping member 21 on the purlin 3, and by arranging the pressing block in a form including a fixing plate 221, a first side pressing plate 2221 and a second side pressing plate 2222, the pressing block will not leak out of the top of the component frame 11, thereby improving the aesthetics of the photovoltaic component.

[0094] It should be noted that, in practical applications, the present invention does not impose any limitation on the specific implementation method of the pressing block against the clamping plate 211 , as long as the pressing block can be pressed against the clamping plate 211 to press the clamping member 21 against the purlin 3 .

[0095] In a specific embodiment, the pressing block is a U-shaped structure (not shown in the figure), and the fixing plate 221 of the pressing block directly abuts against the clamping plate 211 .

[0096] In another specific embodiment, Figure 7 and Figure 8 , Figures 14 to 16 As shown, a first limiting structure (such as a limiting hole 216) is provided on the clamping member 21, and a second limiting structure (such as a limiting plate 224) is provided at the bottom of the pressing block.

[0100] Preferably, the first limiting structure is the limiting hole 216 , and the second limiting structure is the limiting plate 224 .

[0101] It should be noted that the present invention does not impose any limitation on the specific shapes of the limiting hole 216 and the limiting plate 224 , as long as the limiting plate 224 can be inserted into the limiting hole 216 .

[0102] For example, Figure 8 and Fig.16 As shown, the width of the limiting plate 224 is W1, the length of the limiting plate 224 is L1, the width of the limiting hole 216 is W2, and the length of the limiting hole 216 is L2, then W1<W2, L1<L2.

Such adjustment and change of the positional relationship between the first limiting plate 2241, the first side pressure plate 2221 and the second limiting plate 2242, the second side pressure plate 2222 does not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0106] Further preferably, the first limiting plate 2241 and the first side pressing plate 2221 are integrally formed, and the second limiting plate 2242 and the second side pressing plate 2222 are integrally formed.

[0107] It should be noted that the present invention is not limited to setting the first limiting plate 2241 and the first side pressure plate 2221 as an integral part, and setting the second limiting plate 2242 and the second side pressure plate 2222 as an integral part. For example, the first limiting plate 2241 and the first side pressure plate 2221 can also be set to be welded or bonded, and the second limiting plate 2242 and the second side pressure plate 2222 can be set to be welded or bonded. Alternatively, the first limiting plate 2241 and the first side pressure plate 2221 can be fixedly connected or snap-connected by fasteners, and the first limiting plate 2241 and the first side pressure plate 2221 can be fixedly connected or snap-connected by fasteners, and the first limiting plate 2241 and the first side pressure plate 2221 can be fixedly connected or snap-connected by fasteners, and so on.

Of course, preferably, the first limiting plate 2241 and the first side pressure plate 2221 are integrally formed, and the second limiting plate 2242 and the second side pressure plate 2222 are integrally formed.

The photovoltaic module also has a frame top plate 113 and a frame side plate 112. When installed, the side pressure plate 222 is abutted against the frame side plate 112, and the support plate 225 abuts against the purlin 3. The locking member 23 is used to fix the fixing plate 221 on the purlin 3, and the top pressure plate 223 is pressed against the frame top plate 113 so that the clamping member 21 is pressed against the purlin 3.

[0110] Through such an arrangement, the pressing block assembly is suitable for the installation of the photovoltaic assembly located at the end, thereby making the installation of the photovoltaic assembly more flexible.

[0111] Preferably, a first limiting structure is provided on the clamping member 21 , and a second limiting structure is provided on the pressing block. The first limiting structure cooperates with the second limiting structure to prevent the pressing block from moving relative to the clamping member 21 .

[0112] Through such an arrangement, that is, through the cooperation of the first limiting structure and the second limiting structure, it is possible to prevent the pressing block from moving relative to the clamping member 21, thereby avoiding misalignment between the pressing block and the clamping member 21 when the wind force is strong.

[0113] It should be noted that the specific structural forms of the first limiting structure and the second limiting structure, and the size relationship between the first limiting structure and the second limiting structure are the same as those in the second embodiment, and will not be described in detail here.

[0114] Specifically, the first limiting structure is the limiting hole 216 , and the second limiting structure is the limiting plate 224 .

[0115] Preferably, if Figures 10 to 12 As shown, the edge pressure block further includes a support foot 226 disposed at the end of the support plate 225 . When installed, the support plate 225 rests against the purlin 3 via the support foot 226 .

[0116] By providing the support feet 226 , the contact area between the edge pressing block and the purlin 3 can be increased, thereby improving the abutment stability between the pressing block and the purlin 3 , and further improving the installation stability of the photovoltaic module.

[0117] It should be noted that the support foot 226 can be configured to be integrally formed with the support plate 225, or the support foot 226 can be configured to be fixedly connected to the support plate 225, or the support foot 226 can be configured to be detachably connected to the support plate 225, and so on. Such adjustments and changes to the specific connection method between the support foot 226 and the support plate 225 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0118] Preferably, the support foot 226 and the support plate 225 are integrally formed.

[0119] It should be noted that although the present invention introduces the pressing block of the present invention with the above-mentioned several embodiments, this is not restrictive, and any other possible pressing block structure does not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0120] Preferably, if Fig.17 and Fig.18 As shown, the pressing block assembly is arranged between two adjacent photovoltaic components, and a connecting structure is provided on each of the two adjacent clamping members 21. When installed, the connecting structure on one of the clamping members 21 cooperates with the connecting structure on the adjacent clamping member 21 to prevent relative movement between the two adjacent photovoltaic components.

[0121] With such an arrangement, after installation, the connection structures of two adjacent clamps 21 can cooperate with each other to prevent two adjacent photovoltaic modules from slipping due to load, thereby further improving the installation stability of the photovoltaic modules and preventing the photovoltaic modules from falling off.

[0122] It should be noted that, in actual applications, the present invention does not impose any limitation on the specific type of the connection structure. For example, the connection structure can be set as a snap-fit ​​structure, that is, two adjacent clamping members 21 are snap-fitted through the snap-fit ​​structure, or the connection structure can be set as a locking structure, that is, two adjacent clamping members 21 are locked through a locking structure such as a screw, or the connection structure can be set as a plug-in structure, that is, two adjacent clamping members 21 are plug-in connected through a plug-in structure, and so on. Such adjustments and changes to the specific structural type of the connection structure do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0123] Preferably, the connection structure is a snap-on structure, so that the locking and unlocking of two adjacent clamps 21 can be achieved more quickly, thereby improving the installation and disassembly efficiency of the photovoltaic module.

[0124] Specifically, the connection structure includes a first clamping structure 2171 and a second clamping structure 2172 .

[0125] It should be noted that, in actual applications, those skilled in the art may configure the first clamping structure 2171 and the second clamping structure 2172 to be in the form of a buckle and a slot, or may configure the first clamping structure 2171 and the second clamping structure 2172 to be in the form of a block and a hole, or may configure the first clamping structure 2171 and the second clamping structure 2172 to be in any other possible structural form, and so on. Such adjustments and changes to the specific structural forms of the first clamping structure 2171 and the second clamping structure 2172 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0126] Preferably, if Fig.17 and Fig.18 As shown, the first clamping structure 2171 and the second clamping structure 2172 are configured in the form of a buckle and a slot.

[0127] It should be noted that, in practical applications, the present invention does not impose any limitation on the specific arrangement of the first clamping structure 2171 and the second clamping structure 2172 on the clamping member 21, as long as the first clamping structure 2171 and the second clamping structure 2172 can cooperate with each other to prevent relative movement between two adjacent photovoltaic components.

[0128] In a specific embodiment, a first clamping structure 2171 is provided on one of the clamping members 21, and a second clamping structure 2172 is provided on the adjacent clamping member 21. When installed, the first clamping structure 2171 can cooperate with the second clamping structure 2172 to prevent relative movement between two adjacent photovoltaic components.

[0129] In another specific embodiment, a first clamping structure 2171 and a second clamping structure 2172 are provided on two adjacent clamping members 21. When installed, the first clamping structure 2171 on one of the clamping members 21 cooperates with the second clamping structure 2172 on the adjacent clamping member 21, and the second clamping structure 2172 on one of the clamping members 21 cooperates with the first clamping structure 2171 on the adjacent clamping member 21.

[0130] Of course, preferably, Fig.17 and Fig.18 As shown, a first clamping structure 2171 and a second clamping structure 2172 are provided on the clamping member 21. When installed, the first clamping structure 2171 on one of the clamping members 21 cooperates with the second clamping structure 2172 on the adjacent clamping member 21, and the second clamping structure 2172 on one of the clamping members 21 cooperates with the first clamping structure 2171 on the adjacent clamping member 21.

[0131] Through such an arrangement, compared with the form of arranging a first clamping structure 2171 on one of the clamping members 21 and arranging a second clamping structure 2172 on the adjacent clamping member 21, by arranging the first clamping structure 2171 and the second clamping structure 2172 on the clamping member 21 at the same time, on the one hand, the structure of the clamping member 21 can be made more unified, thereby reducing the number of molds and reducing the processing cost of the clamping member 21. On the other hand, when installing the photovoltaic module, since there is no need to distinguish between different types of clamping members 21, the installation efficiency is also higher.

[0132] It should be noted that, in practical applications, the present invention does not impose any limitation on the specific setting type of the locking member 23, as long as the pressure block can be fixed on the purlin 3. For example, the locking member 23 can be set to include a locking bolt 231 and a locking block 232, and the locking bolt 231 can cooperate with the locking block 232 to fix the pressure block on the purlin 3, or the locking member 23 can be directly set as a locking bolt 231, and the locking bolt 231 directly cooperates with the threaded hole on the purlin 3 to fix the pressure block on the purlin 3, or the locking member 23 can be set in any other possible form, etc. Such adjustments and changes to the specific setting type of the locking member 23 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0134] Specifically, Figures 1 to 13 As shown, the locking block 232 is provided with a bolt hole 2322 matched with the locking bolt 231 , and the locking bolt 231 can pass through the fixing plate 221 and match with the bolt hole 2322 to fix the pressing block on the purlin 3 .

The locking block 232 is provided with a groove 2321 adapted to the free end of the purlin 3. When installed, the free end of the purlin 3 is inserted into the groove 2321 to prevent the locking block 232 from falling out of the mounting groove 31.

[0136] Through such a configuration, the locking block 232 can be prevented from escaping from the installation groove 31, thereby further improving the installation stability of the photovoltaic module.

[0137] It should be noted that it is not limited to setting a groove 2321 on the locking block 232 that is compatible with the free end of the purlin 3, and the free end of the purlin 3 is inserted into the groove 2321. For example, the free end of the purlin 3 can also be directly placed against the surface of the locking block 232, and so on. Such flexible adjustment and change does not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0138] It should be noted that the present invention does not impose any limitation on the specific shape of the locking block 232 , as long as the locking block 232 can be installed in the purlin 3 .

[0139] like Figure 2 , Figure 6 , Fig.13 and Fig. 20 As shown, the top of the purlin 3 has an opening 32, and the locking block 232 can enter the installation groove 31 through the opening 32, wherein the width of the locking block 232 is W3, and the width of the opening 32 is W4, then W3<W4.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments.
