[0029] Solar power generation is divided into solar thermal power generation and photovoltaic power generation. Solar power generation usually refers to solar photovoltaic power generation, abbreviated as photovoltaic. Photovoltaic power generation is a technology that directly converts into electrical energy. Photovoltaic power generation mainly relies on solar photovoltaic panels to absorb solar energy and convert it into electrical energy. Photovoltaic panels are usually fixedly installed on purlins, and the angle is adjusted with the rotation of the purlins to obtain more sufficient light. In related technologies, photovoltaic panels and purlins are usually bolted or welded. However, the installation process of photovoltaic panels connected in this way is relatively complicated, and when the photovoltaic panels or purlins fail, there are relatively cumbersome disassembly or replacement steps.

[0030] In order to improve the deficiencies of the above-mentioned prior art, Figures 1 to 6The technical solution of the present invention proposes a locking assembly 100, which is used for a photovoltaic bracket 1000. The photovoltaic bracket 1000 includes a purlin 300 and a photovoltaic panel 500. The purlin 300 and the photovoltaic panel 500 are stacked. The purlin 300 is provided with a through installation slot 310. The locking assembly 100 includes a locking body 10 and a stopper 30. The locking body 10 is formed with a snap-fitting groove 11, and the snap-fitting groove 11 and the installation slot 310 are mutually engaged. The two opposite side walls in the snap-in groove 11 respectively abut against the walls of the photovoltaic panel 500 and the purlin 300 facing away from each other, so that the purlin 300 and the photovoltaic panel 500 are relatively fixed; the retaining member 30 is inserted into the side of the installation slot hole 310 facing away from the lock body 10, and the retaining member 30 has opposite two ends, and respectively abut against the side wall of the installation slot hole 310 facing away from the lock body 10 and the side wall of the lock body 10 facing away from the snap-in groove 11.

[0031] It can be understood that the through-going installation slot 310 provided on the purlin 300 allows the lock body 10 to have a certain space. During the installation process of the photovoltaic bracket 1000, the lock body 10 can first extend into the installation slot 310, and then move its snap-in slot 11 from the opening toward the side wall of the installation slot 310. In this way, the photovoltaic panel 500 stacked on one side of the purlin 300 will be snap-connected with the wall of the side periphery of the installation slot 310 by the snap-in slot 11. The two opposite end surfaces on both sides of the snap-in slot 11 respectively abut against the photovoltaic panel 500 and the purlin 300, so that the purlin 300 and the photovoltaic panel 500 are relatively fixed. In this way, the photovoltaic panel 500 can be quickly connected or disconnected with the purlin 300 by using the lock body 10 through simple manual operation, saving installation time and labor costs.

[0032] It is understandable that the material of the lock body 10 can be aluminum alloy, stainless steel, high-strength plastic or carbon fiber, etc., or special alloy, composite material, etc., and this application does not make specific restrictions on this. The way in which the lock body 10 and the purlin 300 are plugged into each other can easily adjust the angle and position of the photovoltaic panel 500, allowing the installer to flexibly adjust according to specific needs to maximize the solar energy absorption efficiency. For example, in different seasons or lighting conditions, the position of the photovoltaic panel 500 is adjusted to obtain the best power generation effect, further improving the flexibility of the use of the lock assembly 100.

[0033] It should be noted that, compared with the bolt connection or welding connection method, the locking body 10 is provided to fix the photovoltaic panel 500 and the purlin 300. When the surface of the photovoltaic panel 500 is affected by external environmental factors such as dust or droplets, the relative fixed relationship between the purlin 300 and the photovoltaic panel 500 can be cancelled by withdrawing the locking body 10 from the installation slot 310, and the photovoltaic panel 500 can be taken out and cleaned or replaced as needed, thereby further ensuring the power generation efficiency of the photovoltaic panel 500 and the ease of use of the locking assembly 100.

[0034] It can be understood that when the lock body 10 in the installation slot 310 is used to fix the connection between the folded edge 510 or the photovoltaic panel 500 and the purlin 300, the snap-in groove 11 has a tendency to slide in the direction away from the folded edge 510 or the photovoltaic panel 500 and the purlin 300, that is, the lock body 10 may retreat or slide. The stop member 30 is arranged to abut against the side of the lock body 10 away from the fixed end, which limits the retreat or sliding tendency of the lock body 10, further improves the working stability of the lock assembly 100, and avoids the lock body 10 from loosening or falling off due to external force or vibration factors.

[0035] It can be understood that the abutment of the stop member 30 against the lock body 10 ensures the tight connection between the lock body 10 and the folded edge 510 or the photovoltaic panel 500 and the purlin 300, which can prevent the lock body 10 from being accidentally or maliciously pried, and also prevents the lock body 10 from being misoperated or incorrectly installed, thereby increasing the anti-theft and safety performance of the lock assembly 100 and ensuring the correctness of the connection of the lock body 10.

[0036] It should be noted that when the lock assembly 100 provided with the stop member 30 needs to be maintained, replaced or inspected in its connection with the purlin 300 and the photovoltaic panel 500, the lock body 10 can be released by releasing the stop member 30, thereby further simplifying the disassembly and reinstallation process, reducing the wear and loosening of the lock body 10 during long-term use and repeated adjustments, and further improving the service life of the lock assembly 100.

[0037] In one embodiment of the present invention, two sides of the lock body 10 perpendicular to the opening direction of the locking slot 11 respectively abut against two side walls symmetrically arranged in the installation slot hole 310 .

[0038] It can be understood that the two side walls in the installation slot 310, which are symmetrically arranged perpendicular to the opening direction of the snap-in slot 11, respectively abut against the opposite sides of the lock body 10 and provide stable supporting force toward each other. When the lock body 10 is subjected to external force or vibration, the movement tendency of the lock body 10 is hindered, further ensuring the stability of the relative position relationship between the lock body 10 and the installation slot 310.

[0039] Furthermore, in a preferred embodiment, the two sides of the stop member 30 perpendicular to the opening direction of the snap slot 11 also correspond to the two side walls of the abutment lock body 10 symmetrically arranged in the abutment installation slot 310. In this way, the relative two side walls of the installation slot 310 simultaneously limit the possible displacement of the stop member 30 and the lock body 10 in the direction perpendicular to the opening direction of the snap slot 11, ensuring the relative position relationship between the lock body 10, the stop member 30 and the installation slot 310, and further increasing the working stability of the lock assembly 100.

[0040] In one embodiment of the present invention, in conjunction with reference Figure 1 and Figure 2 A folded edge 510 is provided at the periphery of the photovoltaic panel 500, and the folded edge 510 is bent and connected to the photovoltaic panel 500, and an inner end surface of the clamping groove 11 abuts against an end surface of the folded edge 510 close to the photovoltaic panel 500, so that the purlin 300 and the folded edge 510 are relatively fixed.

[0041] It can be understood that when the lock body 10 is inserted into the installation slot 310 and relatively abuts the photovoltaic panel 500 and the purlin 300, the part it clamps is specifically the periphery of the photovoltaic panel 500 and the inner edge of the installation slot 310. Therefore, it can be that the installation slot 310 corresponds to the periphery of the photovoltaic panel 500 and is opened at the edge of the photovoltaic panel 500 away from the photovoltaic panel 500, or it can be an additional folded edge 510 that is bent toward the direction of the photovoltaic panel 500 and connected to the photovoltaic panel 500. At this time, the installation slot 310 is correspondingly set at the edge of the photovoltaic panel 500 on the side close to the photovoltaic panel 500. Preferably, a folded edge 510 is provided to be bent and connected to the photovoltaic panel 500, and the locking body 10 is buckled to connect the periphery of the folded edge 510 and the purlin 300, so that the folded edge 510 and the purlin 300 are relatively fixed, thereby ensuring the relative position relationship between the photovoltaic panel 500 and the purlin 300. In this way, the situation that the space on the side of the purlin 300 at the edge of the photovoltaic panel 500 away from the photovoltaic panel 500 is insufficient to open the installation slot 310 is avoided, thereby further improving the space utilization rate when the photovoltaic panel 500 is installed on the purlin 300.

[0042] It should be noted that the wall surface of the folded edge 510 bent and connected to the photovoltaic panel 500 close to the photovoltaic panel 500 and the wall surface of the photovoltaic panel 500 close to the folded edge 510 together enclose a groove. When the lock body 10 fixes the folded edge 510 and the purlin 300 relatively, one side of its snap-in groove 11 at least partially extends into the groove. When the lock assembly 100 is affected by external forces such as wind or vibration, its tendency to move toward the groove will be blocked by the bottom wall of the groove, which further improves the fixing stability and reliability of the lock assembly 100.

[0043] In one embodiment of the present invention, in conjunction with reference Figure 1 , Figure 3 and Figure 4 The lock body 10 is formed by bending a sheet metal part multiple times to form a frame with open ends. At least two opposite side walls of the lock body 10 are formed with at least two snap-in grooves 11, and at least two snap-in grooves 11 are simultaneously inserted into one side wall of the installation slot hole 310 to relatively fix the folded edge 510 and the purlin 300.

[0044] It can be understood that the frame formed by multiple bending processes of the sheet metal has a hollow polygonal cross-sectional shape, and has at least two sides on which snap-in grooves 11 can be set to simultaneously snap-in and fix the photovoltaic panel 500 and the purlin 300. In this way, the strength that the snap-in grooves 11 can withstand when fixing the photovoltaic panel 500 and the purlin 300 is further improved, and the deformation of the snap-in grooves 11 that may affect the snap-in effect when the locking assembly 100 is affected by external force factors such as wind or vibration is avoided.

[0045] It should be noted that the frame-type lock body 10 that is bent multiple times ensures that its structure is strong and stable, and does not have the possibility of excessive mass that may affect the bearing capacity of the purlin 300 as in the case of a solid lock body 10, and further reduces the production cost of the lock assembly 100. On the other hand, the size of the openings at both ends of the lock body 10 can be changed by adjusting the number of bending processes and other parameters such as the bending angle or length, and then the depth of the insertion of the clamping groove 11 into the side edge of the installation slot 310 can be adjusted to achieve flexible connection in different scenarios, further increasing the flexibility of use of the lock assembly 100.

[0046] In one embodiment of the present invention, Figures 1 to 4 As shown in , the lock body 10 is further provided with a lock tongue 13 , which is protruded from a side wall of the lock body 10 close to the photovoltaic panel 500 toward the folded edge 510 and at least partially abuts against the folded edge 510 .

[0047] It can be understood that the lock tongue 13 is used to abut the wall of the folded edge 510 to further provide additional friction to fix the folded edge 510 and the lock body 10, further avoiding the tendency of the folded edge 510 to detach from the lock body 10 when subjected to external force or vibration, reducing the risk of loosening or falling off, ensuring that the lock body 10 will not accidentally loosen during use, and improving the reliability and stability of the lock body 10 connecting the purlin 300 and the folded edge 510.

[0048] It should be noted that the lock tongue 13 can also increase the difficulty of disassembly, preventing unauthorized disassembly and tampering. It is difficult for unauthorized personnel to release the connection between the folded edge 510 and the purlin 300 of the lock body 10 without proper tools or knowledge, further improving the stability of the lock assembly 100.

[0049] In one embodiment of the present invention, in conjunction with reference Figures 1 to 4 The lock body 10 also includes at least two support plates 15, which are respectively bent and connected to at least two clamping grooves 11, and extend in relatively divergent directions. The support plates 15 abut against a side wall of the purlin 300 away from the folded edge 510.

[0050] It can be understood that at least two support plates 15 respectively abut against the wall surface on both sides of the installation slot 310 away from the folded edge 510, and have a supporting force applied to the purlin 300 at the slot of the installation slot 310, further ensuring the relative position relationship between the purlin 300 and the folded edge 510, thereby avoiding the tendency of the purlin 300 to separate from the lock body 10 toward the bottom under the influence of gravity when subjected to external force or vibration, thereby improving the connection stability of the lock assembly 100 for the purlin 300 and the folded edge 510.

[0051] In one embodiment of the present invention, in conjunction with reference Figure 1 The purlin 300 is provided with at least two mounting slots 310, the locking assembly 100 includes at least two locking bodies 10, and at least two folding edges 510 are provided on the opposite side peripheries of the photovoltaic panel 500, and at least two folding edges 510 are relatively extended. The number of mounting slots 310 and the number of locking bodies 10 correspond to the number of folding edges 510, and the positions of the mounting slots 310 correspond to the folding edges 510. At least two locking bodies 10 are symmetrically arranged in the corresponding two mounting slots 310, so that at least two clamping grooves 11 have opposite opening directions, and the two folding edges 510 are fixed to the purlin 300 respectively.

[0052] It can be understood that the two snap-in grooves 11 with opposite opening directions symmetrically arranged in the two installation slots 310 enable the two folded edges 510 corresponding to the two side edges of a photovoltaic panel 500 to be snap-fitted and fixed to the corresponding installation slots 310 by the lock body 10 respectively. In this way, the pressure and stress on the two folded edges 510 are evenly shared by the two lock bodies 10, reducing the pressure on a single lock body 10, improving the bearing capacity of the overall connection of the lock assembly 100, reducing stress concentration and fatigue damage, further improving the working stability of the lock assembly 100, and avoiding the possible risk of loosening or falling off.

[0053] It is understandable that by providing at least two lock bodies 10, when one lock body 10 is affected by a failure or other factors that affect the connection stability, at least another lock body 10 can still fix the fold 510 and the purlin 300. When the lock body 10 is maintained, replaced or inspected, the stability of the overall connection is always guaranteed, further improving the working stability and maintenance convenience of the lock assembly 100. On the other hand, at least two lock bodies 10 have the same specifications and performance to ensure their continuity and interchangeability, so that the use and maintenance convenience of the lock assembly 100 can be further improved.

[0054] In one embodiment of the present invention, in conjunction with reference Figure 1 , Figure 2 , Figure 5 and Figure 6The cross-section of the retaining member 30 is U-shaped, and at least a portion of the bottom wall of the retaining member 30 is exposed at the notch on the side of the installation slot 310 away from the photovoltaic panel 500.

[0055] It can be understood that the retaining member 30 with a U-shaped cross-section has a lighter weight than a solid retaining member 30 while ensuring its own fixing effect on the lock body 10, thereby ensuring the convenience of installation. The U-shaped bottom wall surface is exposed in the slot of the installation slot 310 on the side away from the photovoltaic panel 500. During inspection, maintenance or disassembly, the retaining member 30 can be detached from the installation slot 310 by applying pressure from the bottom wall surface on this side toward the retaining member 30, which further simplifies the disassembly and reinstallation process and improves the ease of use of the lock assembly 100.

[0056] In one embodiment of the present invention, Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the two opposite side edges of the retaining member 30 are respectively bent and connected with at least two flanges 31, and the at least two flanges 31 are extended in reverse directions and form a first abutting end face 32 close to one side of the purlin 300; the two opposite side walls of the retaining member 30 are respectively protruded with two clamping parts 33, and at least the two clamping parts 33 form a second abutting end face 34 close to one side of the purlin 300, and the first abutting end face 32 and the second abutting end face 34 respectively abut the two opposite side walls of the purlin 300.

[0057] It can be understood that the relatively arranged first abutment end face 32 and the second abutment end face 34 are used to clamp the side walls of the purlin 300 at the side periphery of the installation slot hole 310, which respectively apply pressure toward the purlin 300, further avoiding the tendency of the retaining member 30 to detach from the installation slot hole 310 when the retaining member 30 is affected by external force or vibration, and further improving the installation stability of the retaining member 30 fixed in the installation slot hole 310.

[0058] The technical solution of the present invention further proposes a photovoltaic bracket 1000, which includes any one of the above-mentioned locking components 100. The specific structure of the locking component 100 refers to the above-mentioned embodiment. Since the locking component 100 of this solution adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0059] In a preferred embodiment, the photovoltaic bracket 1000 includes a column 700, a purlin 300, a photovoltaic panel 500 and a locking assembly 100 as described in any of the above embodiments, the purlin 300 is fixedly connected to the column 700, and the locking assembly 100 clamps and fixes the photovoltaic panel 500 to the side of the purlin 300 away from the column 700.

[0060] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
