[0029] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] See also Figure 1-3 One embodiment of the present invention provides a frame 100 of a photovoltaic module, which is used to be installed on the edge of a laminate. The frame 100 is made of a two-dimensional profile. A hanging groove 160 is provided on the bottom of the side wall of the frame 100, and the hanging groove 160 is used to hang the frame 100 on a hanging rod. When the photovoltaic module is installed, the frame 100 can be directly hung on the hanging rod through the hanging groove 160, and the hanging rod is inserted into the hanging groove 160, so that the photovoltaic module is hung on the hanging rod. In the above-mentioned frame 100, the hanging groove 160 is located at the bottom of the side wall, and the laminate is installed in the top area of ​​the frame, so that when the hanging rod is hung in the hanging groove 160, there will be no interference between the laminate and the hanging rod, and it will not affect the hanging of the hanging groove 160 on the hanging rod.

[0031] Optionally, the frame 100 includes a top surface 110, an outer side surface 120, a bottom surface 130, and an inner side surface 140, wherein the top surface 110 is generally referred to as surface A, the outer side surface 120 is generally referred to as surface B, and the bottom surface 130 is generally referred to as surface C. The outer side surface 120 and the inner side surface 140 are both side walls of the frame 100. That is, the outer side surface 120 and the inner side surface 140 are both penetrated by the hanging groove 160.

[0032] In this embodiment, there are two hanging grooves 160. In this way, the upper and lower ends of the photovoltaic module bear force, which is conducive to force distribution and convenient for hanging buckle installation. Of course, it can be understood that the number of hanging grooves 160 is not limited to two, but can be other numbers. Those skilled in the art can select one, three, or even more according to actual conditions.

[0033] Optionally, the hanging groove 160 includes an opening section 161, a hanging section 163, and a sliding introduction section 162 located between the opening section 161 and the hanging section 163; the extension direction of the sliding introduction section 162 is parallel to the extension direction of the frame 100. It can be understood that the opening of the opening section 161 is located at the bottom surface 130, and is disconnected at the opening section 161 at the bottom surface 130. When the frame 100 is hung on the hanging rod, the hanging rod enters from the opening section 161, and then slides along the sliding introduction section 162 to the hanging section 163; after installation, the hanging rod is located at the hanging section 163.

[0034] Optionally, the opening section 161 and the hanging section 163 are located on both sides of the extension direction of the sliding guide section 162. That is, the opening section 161 is located on the side of the sliding guide section 162 close to the bottom surface 130, and the hanging section 163 is located on the side of the sliding guide section 162 close to the top surface 110.

[0035] In this embodiment, the material of the frame is preferably steel, which can reduce the thickness of the frame assembly and reduce the cost of materials. Further preferably, LINE-X coating is coated on the surface of the steel. The LINE-X coating can form a complete sealing layer on the outer layer of the steel material. The sealing layer has high waterproofness and strong weather resistance, and is not prone to corrosion, thereby ensuring the service life of the frame; and the coating has good tensile strength and impact resistance of up to 6600psi, and has good wear resistance, which improves the tensile strength of the frame, avoids scratches or damage after impact, and thus improves the yield of the photovoltaic module.

[0036] The frame of the photovoltaic module has a hanging groove. When the photovoltaic module is installed, the frame can be directly hung on the hanging rod to achieve the installation of the photovoltaic module, which simplifies the installation steps and improves the installation efficiency. There is no need to set a hook on the back of the laminate, which saves materials and avoids the damage to the battery cells in the laminate caused by the tension of the hook. At the same time, the hanging groove is generated when the frame is produced, and the position of the hanging groove is accurate to avoid misalignment, thereby avoiding the problem of difficult or even impossible installation.

[0037] In addition, since the frame is provided with a hanging groove, there is no need to reserve mounting holes and other components on the bottom surface, which can help reduce the width of the bottom surface, save materials and reduce the weight of the frame.

[0038] The invention also provides a photovoltaic module.

[0039] See also Figure 4 A photovoltaic module 200 according to an embodiment of the present invention comprises a laminate and four frames. The four frames are arranged around the edges of the laminate; at least two of the frames arranged opposite to each other are the frames 100 described above.

[0040] Optionally, the frame 100 may be a long frame of a photovoltaic module, and the short frame of the photovoltaic module may be an existing frame without a hanging groove, such as Figure 4 As shown; during installation, the hanging groove 160 of the long frame is hung on the hanging rod. Of course, it can be understood that the above frame can also be the short frame of the photovoltaic module, and the long frame of the photovoltaic module adopts the existing frame without hanging grooves; during installation, the short frame is hung on the hanging rod.

[0041] Optionally, the four frames may also be the frames provided by the present invention. In this way, the hanging position of the photovoltaic module can be freely selected, that is, the long frame can be hung on the hanging rod, or the short frame can be hung on the hanging rod according to actual conditions.

[0042] Optionally, adjacent frames are connected by using angle brackets, which help the frames to form a stable frame edge structure.

[0043] The photovoltaic module adopts the frame provided by the present invention, and can be directly hung on the hanging rod to realize the installation of the photovoltaic module, thereby simplifying the installation steps and improving the installation efficiency. There is no need to set a hook on the back of the laminate, which saves materials and avoids the damage of the battery cell in the laminate caused by the tension of the hook.

[0044] The invention also provides a photovoltaic device.

[0045] See also Figure 5-9 The photovoltaic device of one embodiment of the present invention comprises a mounting mechanism 300 and a photovoltaic module 200 provided by the present invention; the photovoltaic module 200 is mounted on the mounting mechanism 300. The mounting mechanism 300 mainly functions to mount and fix the photovoltaic module 200. Specifically, the mounting mechanism comprises a hanging rod 320. During installation, the hanging groove 160 of the frame 100 of the photovoltaic module 200 is hung on the hanging rod 320.

[0046] Optionally, the installation mechanism 300 further includes a pressing member 310 and a fixing assembly. The main function of the pressing member 310 is to press the photovoltaic assembly 200 toward the hanging rod 320; that is, after installation, the pressing member 310 can prevent the photovoltaic assembly 200 from moving away from the hanging rod 320, thereby limiting the photovoltaic assembly 200 to the area between the pressing member 310 and the hanging rod 320. The main function of the fixing assembly is to fix the pressing member 310 on the hanging rod 320.

[0047] Optionally, the holding member 310 includes a pressing portion 311 for preventing the photovoltaic assembly 200 from moving away from the hanging rod 320, and a connecting portion 312 for sleeve the holding member 310 on the hanging rod; the connecting portion 312 is provided with a connecting hole 313 for the hanging rod 320 to pass through.

[0048] Furthermore, the connection hole 313 is a strip-shaped hole. Since the connection hole 313 is a strip-shaped hole, it can be applicable to photovoltaic modules of different heights.

[0049] Furthermore, the pressing member 310 is in an inverted L-shape or a T-shape, the vertical portion is a connecting portion 312 , and the horizontal portion is a pressing portion 311 .

[0050] Optionally, the hanging rod 320 is provided with a plurality of threaded sections 321 spaced apart from each other; the fixing assembly includes nuts 330 located on both sides of the pressing member 310, and the nuts 330 are sleeved on the threaded sections 321. During installation, the pressing member 310 is first sleeved on the hanging rod 320 through the connecting hole 313, and then the left-right and up-down positions of the pressing member 310 are adjusted. After the position is determined, the nuts 330 located on both sides of the pressing member 310 are simultaneously screwed into the pressing member 310, thereby clamping and fixing the pressing member 310 from both sides.

[0051] In this embodiment, the spacing distance between the thread segments 321 is similar to the distance between the two opposite frames 100 of the photovoltaic module 200, that is, the portion of the hanging rod 320 below the laminate is substantially free of threads. Of course, it is understandable that the entire surface of the hanging rod 320 may be provided with threads.

[0052] In this embodiment, the holding member 310 is divided into two types, one is the edge holding member 310a, which is located on the outside of the edge photovoltaic module and only holds the edge photovoltaic module; the other is the middle holding member 310b, which is located between two adjacent photovoltaic modules and holds both photovoltaic modules at the same time. In other words, the holding member located between two adjacent photovoltaic modules has two pressing pieces; the two pressing pieces are arranged opposite to each other. Of course, it is understandable that there may be only one type of holding member, all of which are edge holding members, so that one edge holding member is arranged on each side of each photovoltaic module, and adjacent photovoltaic modules do not share holding members; or all of which are middle holding members, and the middle holding member located at the edge does not hold the photovoltaic module on one side.

[0053] The following is a brief description of the installation process of the above photovoltaic equipment.

[0054] First, put the nut 330 and the holding piece 310 on the hanging rod 320, ensuring that there is a nut 330 on each side of the holding piece 310, then hang the photovoltaic module 200 on the hanging rod 320, and then adjust the position of the holding piece 310 so that the pressing piece 311 of the holding piece 310 is pressed on the frame 100 of the photovoltaic module, and finally screw the nuts 330 on both sides of the holding piece 310 into the holding piece 310 at the same time, so as to fix the holding piece 310, and then fix the photovoltaic module 200 on the hanging rod 320.

[0055] The photovoltaic device adopts the photovoltaic assembly provided by the present invention, and can directly hang the frame on the hanging rod to achieve the installation of the photovoltaic assembly, thereby simplifying the installation steps of the photovoltaic device and improving the installation efficiency.
