Existing technologies typically utilize photovoltaic modules to absorb solar energy and convert it into electricity for daily use. In practice, photovoltaic modules are typically mounted on rooftops, and existing technologies typically utilize adhesive bonding, clamping, or hot air welding to secure these modules to the rooftop.

[0003] However, when photovoltaic modules are bonded with glue, the glue is prone to aging, resulting in unstable installation of the photovoltaic modules. The commonly used clamps are required to stably fix the photovoltaic modules on the roof. Therefore, the clamp structure is usually complex and uses a lot of materials, resulting in high production costs and cumbersome installation, which reduces the installation efficiency of the photovoltaic modules.

[0005] The embodiment of the present invention is implemented as follows: a photovoltaic module clamp is used to fix the photovoltaic module to the roof panel, comprising:

[0006] The clamping member has a cavity, and a first through hole communicating with the cavity is formed at the upper end of the clamping member. The clamping member includes a first clamping block and a second clamping block. At the upper end of the clamping member, the first clamping block and the second clamping block are buckled together. At the lower end of the clamping member, the first clamping block and the second clamping block are surrounded by a clamping opening communicating with the cavity, and the first clamping block and the second clamping block are both in contact with the roof panel at the clamping opening.

[0007] A pressing block is provided above the clamping member, the pressing block is provided with a second through hole relative to the first through hole, and a gap is provided between the pressing block and the clamping member for clamping the photovoltaic module;

[0008] A fastener passes through the first through hole and the second through hole in sequence to connect the clamp and the pressing block. The fastener is used to tighten the gap so as to clamp the photovoltaic component between the clamp and the pressing block.

[0009] Furthermore, at the upper end of the clamping member, the first clamping block is provided with a first groove, and the second clamping block is provided with a second groove on a side close to the first groove, and the groove wall of the first groove is adapted to be buckled in the second groove.

[0010] Furthermore, in the width direction of the clamping member, the size of the overlapping portion of the first groove and the second groove is set between 2 mm and 5 mm.

[0011] Furthermore, above the first clamping block, a first limit plate is provided on the groove wall of the first groove close to the second clamping block, and the first limit plate extends along the width direction of the first clamping block. Above the second clamping block, a second limit plate is provided on the groove wall of the first groove close to the first clamping block, and the second limit plate extends along the width direction of the second clamping block.

[0012] Furthermore, the first clamping block and the second clamping block have the same size in the length direction and are both set between 30mm and 50mm, and the first clamping block and the second clamping block have the same size in the width direction and are both set between 10mm and 20mm.

[0013] Furthermore, the size of the pressing block in the length direction is the same as that of the first clamping block and the second clamping block, and the size of the pressing block in the width direction is larger than the width of the clamping member.

[0014] Furthermore, the pressing block is provided with anti-slip serrations at one end opposite to the clamping member, and the anti-slip serrations are used to abut against the photovoltaic component.

[0015] Furthermore, the fastener includes a bolt and a nut threadedly connected to the bolt, the bolt includes a head abutting against the bottom of the first groove, the bolt passes through the first through hole and the second through hole in sequence, and the nut is threadedly connected to the bolt above the pressure block for tightening the pressure block.

[0016] The present invention also provides a photovoltaic roof system, comprising:

[0017] Roof panels are used to be installed on the roof;

[0018] Photovoltaic components are arranged on the roof panel;

[0019] In the aforementioned photovoltaic module clamp, the lower end of the clamp is connected to the roof panel, and the upper end and the pressing block press the photovoltaic module tightly.

[0020] Furthermore, the photovoltaic roof system also includes a support, the upper end of the support is connected to the roof panel, and the lower end is fixed to the roof, and the lower end of the clamping member clamps the connection between the roof panel and the support.

The fastener is sequentially passed through the first through hole and the second through hole to connect the pressure block and the clamp, and the pressure block and the clamp press the photovoltaic module tightly. Due to the interaction of forces, the photovoltaic module applies pressure to the first clamp and the second clamp, causing the clamping opening to shrink, so that the first clamp and the second clamp clamp the roof panel, thereby achieving the fixed installation of the photovoltaic module on the roof panel. Therefore, it is only necessary to buckle the first clamp and the second clamp on the roof panel, and then connect the pressure block and the clamp with the fastener to complete the installation of the photovoltaic module on the roof panel, which simplifies the installation steps of the photovoltaic module and improves the installation efficiency of the photovoltaic module. In addition, the photovoltaic module clamp has a simple structure and uses less materials, which reduces the cost of the photovoltaic module clamp. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples.

[0032] Existing technologies typically utilize glue bonding, clamping, or hot air welding to secure photovoltaic modules to rooftops. However, when gluing photovoltaic modules, the glue easily ages, resulting in unstable installation of the photovoltaic modules. Conventional clamps are required to stably secure the photovoltaic modules to the rooftop, and as a result, the clamps are typically complex in structure and require a lot of material. This results in high production costs and cumbersome installation, reducing the efficiency of photovoltaic module installation. Therefore, the present application proposes a photovoltaic module clamp designed to simplify the structure of the photovoltaic module clamp, reduce its production costs, and improve photovoltaic module installation efficiency.

[0033] See also Figures 1 to 3The photovoltaic module clamp proposed in the embodiment of the present invention is used to fix the photovoltaic module 600 to the roof panel 500, including a clamping member 100, a pressure block 200, and a fastener 300. The clamping member 100 has a cavity 140, and a first through hole 130 connected to the cavity 140 is opened at the upper end of the clamping member 100. The clamping member 100 includes a first clamping block 110 and a second clamping block 120. At the upper end of the clamping member 100, the first clamping block 110 and the second clamping block 120 are buckled together. At the lower end of the clamping member 100, the first clamping block 110 and the second clamping block 120 surround a clamping opening connected to the cavity 140. 150, the first clamping block 110 and the second clamping block 120 are both in contact with the roof panel 500 at the clamping opening 150, the pressing block 200 is arranged above the clamping member 100, and the pressing block 200 is provided with a second through hole 210 relative to the first through hole 130. A gap 400 is provided between the pressing block 200 and the clamping member 100 for clamping the photovoltaic component 600, and the fastener 300 passes through the first through hole 130 and the second through hole 210 in sequence to connect the clamping member 100 and the pressing block 200. The fastener 300 is used to tighten the gap 400 so as to clamp the photovoltaic component 600 between the clamping member 100 and the pressing block 200.

[0034] In this manner, the first clamping block 110 and the second clamping block 120 are fastened to the roof panel 500. At the lower end of the clamping member 100, the first clamping block 110 and the second clamping block 120 form a clamping opening 150 to clamp the roof panel 500, thereby achieving installation of the clamping member 100 on the roof panel 500. The fastener 300 is sequentially passed through the first through-hole 130 and the second through-hole 210 to connect the pressing block 200 and the clamping member 100. The pressing block 200 and the clamping member 100 press the photovoltaic module 600 together. Due to the interaction of forces, the photovoltaic module 600 exerts pressure on the first clamping block 110 and the second clamping block 120, causing the clamping opening 150 to shrink, allowing the first clamping block 110 and the second clamping block 120 to clamp the roof panel 500, thereby achieving secure installation of the photovoltaic module 600 on the roof panel 500. In the prior art, the clamps used to secure the photovoltaic module 600 have complex structures and are difficult to install, resulting in high production costs and low installation efficiency. Therefore, the photovoltaic module 600 can be installed on the roof panel 500 by simply fastening the first clamping block 110 and the second clamping block 120 to the roof panel 500 and then connecting the fastener 300 to the pressing block 200 and the clamping member 100. This simplifies the installation steps of the photovoltaic module 600 and improves the installation efficiency of the photovoltaic module 600. In addition, the photovoltaic module fixture has a simple structure, uses less materials, and uses fewer production molds, which reduces the cost of the photovoltaic module fixture.

[0035] It is worth noting that, because the conventional method of fixing the photovoltaic module 600 with glue is prone to aging, the adhesive can lead to unstable installation of the photovoltaic module 600. However, the photovoltaic module clamp is provided to fix the photovoltaic module 600 to the roof panel 500. Because the clamp 100, the pressing block 200, and the fastener 300 all have high structural strength, the photovoltaic module 600 can be stably installed on the roof panel 500 and is not prone to falling off.

[0036] Optionally, in one embodiment, at the upper end of the clamping member 100 , the first clamping block 110 is provided with a first groove 111 , and the second clamping block 120 is provided with a second groove 121 on a side close to the first groove 111 , and the groove wall of the first groove 111 is adapted to be buckled in the second groove 121 .

[0037] Thus, a first groove 111 is formed on the first clamping block 110, and a second groove 121 is formed on the second clamping block 120. The groove wall of the first groove 111 adjacent to the second groove 121 is snapped into the second groove 121, and the groove wall of the second groove 121 adjacent to the first groove 111 is snapped into the first groove 111, thereby achieving the installation between the first clamping block 110 and the second clamping block 120. Since the first clamping block 110 and the second clamping block 120 are only snapped into place by the groove, the convenience of installing the first clamping block 110 and the second clamping block 120 on the roof panel 500 is improved, and the installation efficiency of the clamping member 100 is improved.

[0038] Optionally, in another embodiment, there may be multiple ways of connecting the first clamp 110 and the second clamp 120. A groove may be provided on the side of the first clamp 110 close to the second clamp 120, and a plug-in portion adapted to be snapped into the groove may be provided on the side of the second clamp 120 close to the first clamp 110. The plug-in portion may be adapted to be plugged into the groove to achieve the connection between the first clamp 110 and the second clamp 120.

[0039] Optionally, in one embodiment, in the width direction of the clamping member 100 , the size of the overlapping portion between the first groove 111 and the second groove 121 is set between 2 mm and 5 mm.

[0040] In this way, the overlapping portion of the first groove 111 and the second groove 121 in the width direction of the clamp 100 is set to between 2 mm and 5 mm, making the connection between the first clamp 110 and the second clamp 120 highly stable and less likely to fall off. Furthermore, the first clamp 110 and the second clamp 120 can withstand the reaction force of the photovoltaic module 600, thereby reducing the clamping opening 150, allowing the clamp 100 to clamp the roof panel 500 and improving the installation stability of the clamp 100 on the roof panel 500. If the width of the overlapping portion of the first groove 111 and the second groove 121 is set to less than 2 mm, the smaller the overlapping area of ​​the first groove 111 and the second groove 121, the smaller the contact area between the first clamp 110 and the second clamp 120, thereby reducing the stability of the connection between the first clamp 110 and the second clamp 120. If the width of the overlapping portion of the first groove 111 and the second groove 121 is set to be greater than 5 mm, due to the large overlapping area, the photovoltaic component 600 may be directly pressed on the connection portion between the first clamp block 110 and the second clamp block 120, thereby causing the clamping member 100 to be improperly stressed, resulting in the clamping opening 150 being difficult to shrink, reducing the clamping force of the clamping member 100 on the roof panel 500, and reducing the installation stability of the clamping member 100 on the roof panel 500.

[0041] Optionally, in one embodiment, above the first clamping block 110, a first limiting plate 112 is provided in the groove wall of the first groove 111 close to the second clamping block 120, and the first limiting plate 112 extends along the width direction of the first clamping block 110; above the second clamping block 120, a second limiting plate 122 is provided in the groove wall of the first groove 111 close to the first clamping block 110, and the second limiting plate 122 extends along the width direction of the second clamping block 120.

[0042] In this way, the first limiting plate 112 and the second limiting plate 122 are respectively arranged in the first groove 111 and the second groove 121. When the first clamping block 110 and the second clamping block 120 move away from each other, the first limiting plate 112 and the second limiting plate 122 abut against the first clamping block 110 to reduce the possibility of separation between the first clamping block 110 and the second clamping block 120, thereby improving the stability of the connection between the first clamping block 110 and the second clamping block 120.

[0043] Optionally, in another embodiment, there may be multiple ways to enhance the connection stability between the first clamp block 110 and the second clamp block 120. A magnetic attraction component may be provided on the groove wall of the first groove 111 or the second groove 121. When the first clamp block 110 and the second clamp block 120 are buckled together, the first clamp block 110 and the second clamp block 120 are adsorbed together by the magnetic attraction component, thereby improving the connection stability between the first clamp block 110 and the second clamp block 120.

[0044] Optionally, in one embodiment, the first clamp block 110 and the second clamp block 120 have the same size in the length direction and are both set between 30 mm and 50 mm, and the first clamp block 110 and the second clamp block 120 have the same size in the width direction and are both set between 10 mm and 20 mm.

[0045] In this way, the length dimensions of the first clamp block 110 and the second clamp block 120 are the same, both being set between 30 mm and 50 mm. This allows the length dimensions of the first clamp block 110 and the second clamp block 120 to be set within a more appropriate range, making the dimensions of the first clamp block 110 and the second clamp block 120 smaller than those of existing clamps. Furthermore, the first clamp block 110 and the second clamp block 120 can have a larger contact area with the photovoltaic module 600, allowing the photovoltaic module clamp to more stably secure the photovoltaic module 600. If the length dimensions of the first clamp block 110 and the second clamp block 120 are set to less than 30 mm, the smaller length dimensions of the first clamp block 110 and the second clamp block 120 will result in a smaller contact area between the first clamp block 110 and the second clamp block 120 and the photovoltaic module 600, causing the photovoltaic module 600 to easily shift on the clamp 100, thereby reducing the stability of the photovoltaic module 600 when installed on the roof panel 500. If the length of the first clamping block 110 and the second clamping block 120 is set to be greater than 50 mm, the length of the clamping member 100 will be larger, and the size of the photovoltaic module clamp will be larger, resulting in more materials used in the photovoltaic module clamp and higher production costs.

[0046] If the width of the first clamping block 110 and the second clamping block 120 is set to be less than 10 mm, the contact area between the first clamping block 110 and the second clamping block 120 and the photovoltaic module 600 is small due to the small width, causing the photovoltaic module 600 to easily shift on the clamping member 100, thereby reducing the stability of the photovoltaic module 600 when installed on the roof panel 500. If the width of the first clamping block 110 and the second clamping block 120 is set to be greater than 20 mm, the width of the clamping member 100 is larger, and the size of the photovoltaic module clamp is larger, resulting in more materials used in the photovoltaic module clamp and higher production costs.

[0047] Preferably, the length of first clamp 110 and second clamp 120 is set to 40 mm, and the width of first clamp 110 and second clamp 120 is set to 15 mm. This makes the overall size of first clamp 110 and second clamp 120 smaller than existing clamps, resulting in a smaller size of the photovoltaic assembly 600 clamp, less material used, and lower production costs. Furthermore, the first clamp 110 and second clamp 120 can have a larger contact area with photovoltaic assembly 600, making photovoltaic assembly 600 less likely to shift.

[0048] Optionally, in one embodiment, the length dimension of the pressing block 200 is the same as that of the first clamping block 110 and the second clamping block 120 , and the width dimension of the pressing block 200 is greater than that of the clamping member 100 .

[0049] In this way, the length dimension of the pressing block 200 is set to be the same as the dimension of the first clamping block 110 and the second clamping block 120, and the width dimension of the pressing block 200 is set to be larger than the width dimension of the clamping member 100, so that the projection of the pressing block 200 on the clamping member 100 can completely cover the clamping member 100, thereby increasing the contact area between the pressing block 200 and the photovoltaic component 600, making it less likely for the photovoltaic component 600 to shift between the clamping member 100 and the pressing block 200, thereby improving the installation stability of the photovoltaic component 600.

[0050] Optionally, in another embodiment, the size of the pressing block 200 can be set in various situations. The size of the pressing block 200 in the width direction can also be set to be the same as the width size of the clamping member 100, thereby reducing the overall size of the pressing block 200 and reducing the production cost of the pressing block 200.

[0051] Optionally, in one embodiment, an end of the pressing block 200 opposite to the clamping member 100 is provided with anti-slip serrations 220 , and the anti-slip serrations 220 are used to abut against the photovoltaic assembly 600 .

[0052] In this way, anti-slip serrations 220 are provided at one end of the pressing block 200 opposite to the clamping member 100, and the anti-slip serrations 220 are abutted against the photovoltaic assembly 600, thereby increasing the friction between the pressing block 200 and the photovoltaic assembly 600, making it difficult for the photovoltaic assembly 600 to shift between the pressing block 200 and the clamping member 100, thereby improving the installation stability of the photovoltaic assembly 600.

[0053] Optionally, in another embodiment, there are multiple ways to increase the installation stability of the photovoltaic assembly 600 between the clamp 100 and the pressing block 200. A rubber pad may be provided at one end of the pressing block 200 that contacts the photovoltaic assembly 600 to increase the friction between the pressing block 200 and the photovoltaic assembly 600 and improve the installation stability of the photovoltaic assembly 600.

[0054] Optionally, in one embodiment, the fastener 300 includes a bolt 310 and a nut 320 threadedly connected to the bolt 310, the bolt 310 includes a head 311 abutting against the bottom of the first groove 111, the bolt 310 passes through the first through hole 130 and the second through hole 210 in sequence, and the nut 320 is threadedly connected to the bolt 310 above the pressing block 200 for pressing the pressing block 200.

[0055] In this manner, the head 311 of the bolt 310 abuts the bottom of the first groove 111, applying an external force toward the photovoltaic module 600 to the upper end of the first clamping block 110, thereby enhancing the connection stability between the first clamping block 110 and the second clamping block 120. The nut 320 is positioned above the pressing block 200 to press the pressing block 200 against the photovoltaic module 600. The photovoltaic module 600 applies pressure to the second clamping block 120, forcing the lower end of the second clamping block 120 toward the lower end of the first clamping block 110, thereby reducing the size of the clamping opening 150. This allows the first and second clamping blocks 110, 120 to clamp the roofing panel 500 at the clamping opening 150, thereby enhancing the installation stability of the first and second clamping blocks 110, 120, on the roofing panel 500.

[0056] The fastener 300 is configured as a structure of a bolt 310 and a nut 320 to simplify the structure of the fastener 300 , reduce the mold development cost of the photovoltaic module fixture, and lower the production cost of the photovoltaic module 600 .

[0057] See also Figures 4 and 5 The present invention also provides a photovoltaic roofing system comprising a roof panel 500, a photovoltaic module 600, and the aforementioned photovoltaic module clamp. The roof panel 500 is mounted on a roof 700, and the photovoltaic module 600 is mounted on the roof panel 500. The lower end of the clamp 100 is connected to the roof panel 500, and the upper end and the pressing block 200 press the photovoltaic module 600. The specific structure of the photovoltaic module clamp is similar to that of the above-mentioned embodiments. Since the present photovoltaic roofing system utilizes all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, and will not be further described here.

[0058] Optionally, in one embodiment, the photovoltaic roof system further includes a support 800 , the upper end of the support 800 is connected to the roof panel 500 , and the lower end is fixed to the roof 700 , and the lower end of the clamp 100 clamps the connection between the roof panel 500 and the support 800 .

[0059] Thus, support 800 is provided, with its upper end connected to roof panel 500 and its lower end fixed to roof 700, thereby securing roof panel 500 to roof 700 and achieving installation of roof panel 500 on roof 700. Furthermore, the lower end of clamp 100 clamps the connection between roof panel 500 and support 800. Because the photovoltaic module clamp holds photovoltaic module 600 and is connected to support 800, the installation height of photovoltaic module 600 is lower than that of existing clamps. Consequently, wind resistance to photovoltaic module 600 is reduced, making it less susceptible to displacement due to high wind pressure, and thus increasing the service life of photovoltaic module 600.

[0060] It is understandable that those skilled in the art can, under the guidance of the above embodiments, combine various implementation methods in the above embodiments to obtain technical solutions of multiple implementation methods.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
