[0044] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0045] Embodiment 1

[0046] like Figure 1 As shown, this embodiment provides a photovoltaic system, which includes a photovoltaic module, a bracket 40 and a photovoltaic module mounting structure, wherein the photovoltaic module includes a laminate (not shown) and a frame 30, and the laminate is arranged in the frame 30. The guide rail 10 is arranged on the bracket 40, and the frame 30 is installed on the bracket 40 through the photovoltaic module mounting structure.

[0047] The laminate of this embodiment is a rectangular structure, and includes a front plate, a rear plate, and a battery cell string arranged between the front plate and the rear plate. The front plate, the battery cell string, and the rear plate are laminated by a laminator to form a laminate.

[0048] The frame 30 is a rectangular frame structure, which is used to encapsulate and protect the edges of the laminate to prevent damage to the laminate. Specifically, the frame 30 includes two first frames 301 and two second frames 302 that are arranged opposite to each other. The first frame 301 and the second frame 302 are sleeved on the corresponding side edge of the laminate to encapsulate and protect the laminate, thereby increasing the pressure resistance of the photovoltaic module and extending the service life of the photovoltaic module.

[0049] The ends of the first frame 301 and the second frame 302 are butted together, so that the first frame 301 and the second frame 302 are spliced ​​into a whole and fixed to the laminate. In order to improve the butt joint effect between the first frame 301 and the second frame 302, the butt joint end faces of the first frame 301 and the second frame 302 can be matched inclined surfaces, thereby increasing the contact area of ​​the first frame 301 and the second frame 302, and the splicing effect is good.

[0050] like Figure 1 and Figure 2 As shown, this embodiment also discloses a photovoltaic installation structure. The photovoltaic installation structure includes a locking member 20 and a guide rail 10, the locking member 20 is installed on the guide rail 10, and the frame 30 of the photovoltaic module slides on the guide rail 10 along the length direction of the guide rail 10 until it is matched with the locking member 20 for installation.

[0051] The locking member 20 of this embodiment has a simple structure, and the locking member 20 is slidably installed with the frame 30, which is easy to install. There is no need to use a large number of fasteners such as bolts and nuts or costly installation clips and their corresponding installation tools, which reduces the workload and installation cost of photovoltaic module installation and improves the installation efficiency and installation quality of the photovoltaic system. Since there is no need to use bolts or installation clips, the stress concentration of the frame 30 and the guide rail 10 is reduced, and the structural strength of the photovoltaic system is improved.

[0052] like Figure 3 and Figure 4 As shown, this embodiment further discloses a locking member 20, which includes a locking portion 1, a plug-in portion 2 and a guide portion 3. The locking portion 1 protrudes from the guide rail 10, and is provided with a clamping groove for clamping the frame 30 of the photovoltaic module. The plug-in portion 2 is connected to the locking portion 1, and the plug-in portion 2 is used to plug and match with the guide rail 10. The guide portion 3 is connected to the locking portion 1, and is provided with a guiding inclined surface, one end of the guiding inclined surface is flush with the notch of the clamping groove, and the other end extends downwardly along the length direction of the guide rail 10.

[0053] The installation process of the locking member 20 and the frame 30 is as follows: the locking member 20 is fixed to the guide rail 10 through the plug-in part 2, the frame 30 of the photovoltaic module slides along the length direction of the guide rail 10, and is slidably inserted into the clamping groove of the locking part 1 through the guide part 3 of the locking member 20, and the clamping groove realizes the fixed installation of the frame 30 and the guide rail 10.

[0054] Continue as Figure 3 and Figure 4 As shown, the locking portion 1 includes a bearing plate 11, a first limiting portion 12 and a second limiting portion 13. The bearing plate 11 is used to support the frame 30. The first limiting portion 12 and the second limiting portion 13 are both arranged on the bearing plate 11 and are spaced apart along the length direction of the guide rail 10. A clamping groove is formed between the first limiting portion 12 and the second limiting portion 13, and the guide portion 3 is connected to the second limiting portion 13.

[0055] The first limiting portion 12 of the present embodiment is U-shaped, and includes a top plate 121 and two side plates 122 respectively connected to the top plate 121 and arranged opposite to each other. One of the two side plates 122 is connected to the supporting plate 11, and at least one of the two side plates 122 is provided with a plug-in portion 2.

[0056] It should be noted that the locking portion 1 has two relatively arranged clamping grooves in the length direction of the guide rail 10. The two clamping grooves can respectively clamp two frame frames 30 with opposite sliding directions on the guide rail 10, so that the same locking member 20 can clamp two frame frames 30 at the same time, which simplifies the structure of the locking member 20 and improves the clamping efficiency of the locking member 20.

[0057] The locking part 1 has two oppositely arranged bearing plates 11 at both ends of the guide rail 10 in the length direction. The bearing plates 11 extend along the length direction of the guide rail 10, and the portion exceeding the first limiting portion 12 forms the bottom wall of the corresponding clamping groove to support the second frame 302. The first limiting portion 12 forms a groove wall of the corresponding clamping groove at both ends of the guide rail 10 in the length direction, and the two second limiting portions 13 form the other groove wall of the corresponding clamping groove, and the two groove walls jointly clamp the second frame 302 that slides into the clamping groove. Since the structures of the two clamping grooves are the same, for ease of understanding, the following description will only take the structure of one of the clamping grooves as an example.

[0058] like Figure 4 and Figure 5 As shown, the first limit portion 12 is formed by integrally bending a sheet metal, and the top plate 121 is connected to two side plates 122 to form a U-shaped structure. One of the side plates 122 is extended with a bearing plate 11 and a plug-in portion 2, and the other side plate 122 is only extended with a plug-in portion 2.

[0059] The support plate 11 is horizontally arranged and vertically connected to the corresponding side plate 122. The horizontally arranged support plate 11 is conducive to increasing the contact area between the clamping groove and the second frame 302, and improving the stability of the installation of the frame 30 and the locking member 20.

[0060] Preferably, both side panels 122 are provided with an inserting portion 2 , and when the inserting portion 2 on one of the two side panels 122 is inserted and matched with the guide rail 10 , the inserting portion 2 on the other of the two side panels 122 abuts against the guide rail 10 .

[0061] One of the side plates 122 of the first position-limiting portion 12 of the present embodiment has two bearing plates 11 and a plug-in portion 2, wherein the two oppositely disposed bearing plates 11 are spaced apart along the length direction of the guide rail 10, and the plug-in portion 2 is located between the two bearing plates 11. The other side plate 122 has two plug-in portions 2, and the two plug-in portions 2 are spaced apart along the length direction of the guide rail 10.

[0062] Continue as Figure 4 and Figure 5 As shown, the plug-in parts 2 on the two side plates 122 are staggered along the width direction of the guide rail 10, which is beneficial to improve the strength and stability of the plug-in fit between the plug-in parts and the guide rail.

[0063] The plug-in portion 2 of this embodiment is a plug-in plate, and the guide rail 10 is provided with a mounting hole 101 that matches the plug-in plate.

[0064] Specifically, the plug board is a rectangular plate, the guide rail 10 is formed of sheet metal in one piece, and the longitudinal section is roughly V-shaped. The upper end surface of the guide rail 10 near the side wall is provided with a mounting hole 101, so that the plug board is inserted into the mounting hole 101 and abuts against the inner surface of the side wall, thereby improving the stability of the insertion.

[0065] The specific assembly relationship between the locking member 20 and the guide rail 10 is as follows: when the two plug-ins on the same side plate 122 are respectively inserted into the corresponding mounting holes 101 on the guide rail 10, the two plug-ins abut against the inner surface of the side wall of the guide rail 10, and the plug-ins on the other side plate 122 abut against the outer surface of the side wall of the guide rail 10. The three plug-ins on the two side plates 122 are staggered and together form a clamping body that clamps the side wall of the guide rail 10, so that when the plug-ins are plugged into and matched with the guide rail 10, the clamping body composed of the plug-ins can clamp the side wall of the guide rail 10, further enhancing the installation stability of the locking member 20 and the guide rail 10, which is beneficial to improving the structural strength of the photovoltaic system.

[0066] Of course, the number of plug plates can also be adjusted according to the specific length of the locking member 20. For example, two plug plates are arranged at intervals on the side plate 122 connected to the supporting plate 11, and three plug plates are arranged at intervals on the other side plate 122. The number of mounting holes 101 on the guide rail 10 is adaptively adjusted.

[0067] Preferably, a spring sheet 21 is provided on the plug board, and a fixing hole 102 cooperating with the spring sheet 21 is opened on the guide rail 10 . When the plug board is plugged into the corresponding mounting hole 101 , the spring sheet 21 is snap-fitted into the corresponding fixing hole 102 .

[0068] The plug board has an elastic sheet 21 inclined toward the side wall of the guide rail 10 . The side wall of the guide rail 10 is provided with a fixing hole 102 . When the plug board is plugged into the mounting hole 101 , the elastic sheet 21 is clamped into the corresponding fixing hole 102 .

[0069] The spring piece 21 of this embodiment is formed by stamping the plug plate, which is conducive to simplifying the structure of the plug plate and reducing the processing cost. The spring piece 21 protrudes from the plug plate and faces the side of the side wall of the guide rail 10 to be inserted into the corresponding fixing hole 102. Moreover, the spring piece 21 on the plug plate that abuts against the inner surface and the outer surface of the side wall of the guide rail 10 has opposite inclination directions.

[0070] The first limiting portion 12 and the second limiting portion 13 are arranged at intervals along the width direction of the guide rail 10, which is conducive to improving the clamping strength of the clamping groove on the second frame 302 and preventing the second frame 302 from deflecting in the clamping groove. The carrier plate 11 is vertically connected to a side plate 122 on one side of the width direction of the guide rail 10, and the carrier plate 11 on one side of the length direction of the guide rail 10 exceeds the end corresponding to the first limiting portion 12 and is connected to the second limiting portion 13.

[0071] The second limiting portion 13 of the present embodiment is a rectangular plate, which is vertically arranged and protrudes from the guide rail 10 , so as to be able to clamp the second frame 302 sliding into the clamping groove together with the first limiting portion 12 .

[0072] The guide portion 3 is a rectangular plate, one end of which is connected to the top of the second limiting portion 13, and the other end is equal to or less than the height of the guide rail 10. The upper end surface of the guide portion 3 is a guiding inclined surface, so as to capture the frame 30 sliding on the guide rail 10 and avoid interference between the second limiting portion 13 and the frame 30. The guide portion 3 extends downwardly along the length direction of the guide rail 10. When the frame 30 slides along the guide rail 10, it can be captured by the guide portion 3 and slides along the guiding inclined surface on the guide portion 3 into the clamping groove.

[0073] The specific process of the guide portion 3 capturing the frame 30 is as follows: when the locking member 20 is installed on the guide rail 10, the frame 30 slides on the guide rail 10 along the length direction of the guide rail 10, and when the second frame 302 of the frame 30 slides to the guide portion 3, it can slide along the guide slope until it is loaded into the accommodating cavity. At this time, the carrying plate 11 supports the bottom of the second frame 302, and the first limiting portion 12 and the second limiting portion 13 jointly clamp the second frame 302, thereby achieving the fixed installation of the frame 30 and the guide rail 10.

[0074] It should be noted that the material of the locking member 20 of the present embodiment is high elastic steel to ensure that the bearing plate 11 and the second limiting portion 13 have good elasticity. When the second frame 302 of the frame 30 slides on the guide portion 3, the bearing plate 11, the second limiting portion 13 and the guide portion 3 are bent downward under the gravity of the frame 30 to reduce the height of the second limiting portion 13, so that the second frame 302 of the frame 30 can be quickly installed in the clamping groove. After the second frame 302 is installed in the clamping groove, the bearing plate 11, the second limiting portion 13 and the guide portion 3 are reset.

[0075] The supporting plate 11 is provided with a partition channel 111 . The partition channel 111 extends along the length direction of the guide rail 10 and passes through the end surface of the supporting plate 11 close to the second limiting portion 13 . The partition channel 111 is located between the first limiting portion 12 and the second limiting portion 13 .

[0076] By providing the partition channel 111 on the bearing plate 11, the bearing plate 11 is connected to the second limiting portion 13 to form a cantilever beam structure, which enhances the elasticity of the second limiting portion 13, thereby increasing the bending amplitude of the second limiting portion 13 in the vertical direction, which is beneficial to the rapid installation of the frame 30 and the guide rail 10. At the same time, the partition channel 111 reduces the weight of the bearing plate 11, which is beneficial to the lightweight of the locking member 20.

[0077] It should be noted that a protective layer is provided on the surface of the frame 30 , and the protective layer may be an anti-oxidation layer, which is beneficial to prolonging the service life of the frame 30 in harsh environments.

[0078] The locking member 20 further includes a piercing portion 4 , which is connected to the locking portion 1 . The piercing portion 4 is configured to pierce the protective layer of the frame 30 and abut against the frame 30 when the frame 30 is slidably inserted into the clamping groove.

[0079] The piercing portion 4 can pierce the protective layer of the frame 30 and abut against the frame 30, so that the frame 30 can be reliably grounded through the locking member 20, the guide rail 10 and the bracket 40, thereby improving the safety of the photovoltaic system during use.

[0080] Continue as Figure 4 and Figure 5 As shown, the piercing portion 4 includes an inclined plate, which is arranged on the supporting plate 11 , and is inclined from bottom to top along the length direction of the guide rail 10 . A sharp protrusion is arranged on the top of the inclined plate, and the sharp protrusion abuts against the frame 30 .

[0081] The piercing portion 4 of this embodiment is formed on the inner wall of the partition channel 111, and has a compact structure, which reduces the volume of the locking member 20. At the same time, the end of the piercing portion 4 is widened, thereby increasing the number of sharp protrusions to increase the contact area between the piercing portion 4 and the second frame 302, which is conducive to reliable grounding of the frame 30.

[0082] The sharp protrusions are arranged in a plurality, and the plurality of sharp protrusions form a sawtooth structure, which is convenient for quickly piercing the protective layer of the frame 30. The inclined plate of this embodiment can pierce the protective layer of the inner wall of the second frame body 302 and abut against the pierced part of the inner wall of the second frame body 302.

[0083] Preferably, a sharp protrusion is provided on the first limiting portion 12 and / or the second limiting portion 13. In order to achieve reliable grounding of the frame 30, the first limiting portion 12 participating in the formation of the clamping groove is provided with a sharp protrusion at the end of the guide rail 10 in the length direction and / or the inner wall of the second limiting portion 13, and the clamping groove and the piercing portion 4 can both pierce the protective layer of the second frame 302, so that the clamping groove has an auxiliary grounding function, and avoids the piercing portion 4 failing to pierce the protective layer of the second frame 302, resulting in the frame 30 not being effectively grounded.

[0084] Embodiment 2

[0085] like Figure 6 As shown, this embodiment provides a photovoltaic system, which is different from the first embodiment in that the structure and puncture position of the puncture portion 4 of the locking member 20 are different.

[0086] The piercing portion 4 and the second limiting portion 13 of this embodiment are respectively located on both sides of the partition channel 111. The piercing portion 4 is formed at the end of the supporting plate 11 close to the corresponding second limiting portion 13. The piercing portion 4 extends along the direction of the guide rail 10 and is bent toward the first limiting portion 12 at the end to form an inclined plate.

[0087] The inclined plate is inclined toward the corresponding first limiting portion 12, and the end of the inclined plate also has a sharp protrusion, which has the same structure as the sharp protrusion in the first embodiment, and is a sawtooth structure. The sharp protrusion can pierce the protective layer of the second frame body 302 when the second frame body 302 of the frame 30 is installed in the clamping groove, and abut against the piercing portion 4 of the second frame body 302, so that the frame 30 is reliably grounded.

[0088] It should be noted that the piercing portion 4 of this embodiment can pierce the protective layer of the outer wall of the second frame body 302 and abut against the pierced portion of the outer wall of the second frame body 302 .

[0089] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention.
