Description

Technical Field

[0001] This invention relates to the field of photovoltaic module technology, and in particular to a photovoltaic frame connector. Background Technology

[0002] A photovoltaic (PV) frame typically refers to the external frame of a solar photovoltaic (PV) module. Its main function is to protect the structural stability of the PV module and provide fixation, support, and installation. The materials and design of PV frames usually take into account factors such as strength, weather resistance, and lightweight. During the assembly of PV frames, PV frame connectors are typically used to securely connect the various structural components of the PV frame.

[0003] Patent CN119945295A relates to a photovoltaic frame connector and its connection method, comprising a body, a connecting strip, and an embedded part. The body includes two sleeves arranged vertically, each sleeve having a receiving cavity with an inner groove on its inner wall. The embedded part includes an embedded element located inside the receiving cavity, connected to the inner wall of the receiving cavity via the connecting strip. The embedded element, connecting strip, and receiving cavity form an integrated structure. This photovoltaic frame connector and its connection method employ a mortise and tenon structure design, allowing for easy installation via a push-in operation between the body and the embedded part. After installation, the connector body and the photovoltaic frame profile are integrated, resulting in high overall strength and effectively preventing deformation of the connector under stress. Utilizing the connector's plasticity, it is applicable to various composite profiles, including those with and without felt, and can meet diverse usage requirements.

[0004] However, photovoltaic frames are generally made of aluminum alloy or other metal materials, and mortise and tenon joints require materials with good cutting and joining properties. This makes the equipment prone to cracking or deformation during the production process. Since photovoltaic modules are usually used outdoors, the mortise and tenon gaps made to ensure the mortise and tenon joints can become potential sources of corrosion, thus affecting the service life of the equipment. Furthermore, because metal parts have greater friction, although metal buckles are generally stronger than wooden connections, they are not as easy to disassemble as wooden structures. Therefore, more force or special tools are needed to loosen and disassemble the connection. Hence, a photovoltaic frame connector is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art by providing a photovoltaic frame connector.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a photovoltaic frame connector, comprising two positioning components and one connecting component. Each of the two positioning components includes a bidirectional telescopic component. A top plate is fixedly connected to the top of the bidirectional telescopic component. A retaining column is fixedly connected to the top of the top of the top plate away from the center of the connecting component. A bottom plate is fixedly connected to the bottom of the bidirectional telescopic component. The connecting component includes a support plate. Four telescopic rods are fixedly connected to the top of the support plate. Push plates are fixedly connected to the tops of two of the telescopic rods. An operating groove is formed on the top of the support plate. A rotating rod is rotatably connected to the center of the operating groove. A cam is fixedly connected to the outer surface of the rotating rod. The operating groove is located away from the center of the support plate. The front and rear ends of one side are provided with sliding grooves. A first spring is fixedly connected to the bottom of the sliding groove. A sliding plate is fixedly connected to the top of the first spring. A liquid transfer component is fixedly connected to the top of the sliding plate. A connecting column is fixedly connected to the bottom of the sliding plate. A rack plate is fixedly connected to the side wall of the sliding plate. The bidirectional telescopic component includes a groove column. A first sliding cavity and a second sliding cavity are formed inside the groove column. A sliding rod is slidably connected to the groove at the bottom of the second sliding cavity. A limit plate is fixedly connected to the top of the sliding rod. The bottom of the sliding rod is connected to the top of the base plate. A second spring is fixedly connected to the top of the first sliding cavity. A reset plate is fixedly connected to the bottom of the second spring. A movable rod is fixedly connected to the top of the reset plate. The top plate is connected to the bottom of the top plate. The bottom of the bottom plate has a through-groove, the inner diameter of which is equal to the outer diameter of the connecting column. The side of the rack plate closest to the center of the support plate contacts the non-convex surface of the cam. When connecting to the photovoltaic frame, first, the two top plates and the bottom plate are placed into the L-shaped and straight frames of the photovoltaic frame, respectively. Then, the two sides of the support plate are placed between the two top plates and the bottom plate. Through the reaction force of the first spring, the connecting column passes through the through-groove and connects to the bottom of the L-shaped and straight frames. After passing through the through-groove, the connecting column also connects to the bottom plate, thereby connecting the positioning component and the connecting component. Because the rack plate moves with the connecting column, the connecting column will cause the rack plate to move during connection. The rack plate drives the cam to rotate, which in turn moves the push plate, along with the top plate and the retaining post, upwards. This allows the retaining post to connect to the top of the L-shaped and straight frames, and also to secure the photovoltaic structure placed on the L-shaped and straight frames. This improves connection efficiency and increases the stability of the photovoltaic frame for the photovoltaic structure. When disassembling the photovoltaic frame, applying an upward force to the connecting post connected to the bottom of the L-shaped and straight frames causes the rack plate to apply a counter-rotating force to the cam. The reaction force of the second spring then drives the retaining post to separate from the L-shaped, straight frames, and the photovoltaic structure. Finally, the L-shaped and straight frames can be separated by pulling them outwards.This improved disassembly efficiency.

[0007] In the aforementioned photovoltaic frame connector, a column receiving groove is provided on the opposite side of the top plate and the bottom plate. The inner diameter of the column receiving groove is equal to the outer diameter of the column. When the positioning component is retracted, the column receiving groove allows the column to enter the interior of the top plate and the bottom plate. Therefore, after applying a force for relative movement to the top plate and the bottom plate, the distance between the top plate and the bottom plate can be greatly reduced, thereby reducing the footprint of the positioning component and improving storage capacity.

[0008] In the aforementioned photovoltaic frame connector, the liquid transfer assembly includes a liquid-passing plate. A liquid guide plate is fixedly connected to the bottom of the inner cavity of the liquid-passing plate. A liquid transfer tube is fixedly connected to the top of the liquid-passing plate in a circumferential array. A liquid guide groove is formed around the top of the top plate near the retaining column. A drain groove is formed in a circumferential array at the bottom of the liquid guide groove. Liquid passage grooves are formed in a circumferential array on the top of both sides of the push plate. A connecting groove is formed at the bottom of the liquid passage groove. The inner surface of the connecting groove is connected to the outer surface of the top of the liquid transfer tube. The two sides of the bottom of the inner cavity of the liquid-passing plate are connected to the top of the connecting column. Liquid outlet channels are provided on both sides of the part. After liquid enters the photovoltaic frame, the liquid guide channel can guide the liquid to the drain channel through its inclined channel edge. Then, the liquid is discharged to the liquid transmission pipe connected to the connecting channel through the liquid passage channel. The liquid transmission pipe then guides the liquid into the interior of the liquid passage plate, and then through the liquid guide plate to the outlet channel. Finally, the liquid is discharged through the outlet channel. Because the connecting column after connection is located on the bottom outside of the photovoltaic frame, the liquid discharged from the outlet channel will not come into contact with the photovoltaic frame, thereby improving the corrosion resistance of the photovoltaic frame.

[0009] In the aforementioned photovoltaic frame connector, the top plate has first locking blocks on both sides of its front and rear ends for engaging with the photovoltaic frame, and the bottom plate has second locking blocks on both sides of its front and rear ends for engaging with the photovoltaic frame. When the top and bottom plates are connected to the L-shaped or straight frame, the first and second locking blocks can be used to position and secure the top and bottom plates entering the L-shaped or straight frame, thereby preventing the top and bottom plates from shifting and improving the placement efficiency of the support plate, thus improving the installation efficiency of the equipment.

[0010] Compared with existing technologies, the advantages of this photovoltaic frame connector are:

[0011] 1. This photovoltaic frame connector, through the cooperative arrangement of a connecting component and two positioning components, allows the two positioning components to be placed inside the L-shaped and straight frames respectively by pushing during the connection process with the L-shaped and straight frames of the photovoltaic frame. Then, through the reaction force of the first spring and the rotational thrust of the cam, the connecting post included in the connecting component is inserted and fixedly connected to the bottom of the L-shaped and straight frames and the base plate included in the positioning component. Furthermore, the limiting post included in the positioning component is connected to the top of the L-shaped and straight frames and the bottom of the photovoltaic module connected to the photovoltaic frame. The pushing connection method is not only simple to operate, but also reinforces the photovoltaic module connected to the photovoltaic frame, thereby improving functionality.

[0012] 2. This photovoltaic frame connector, through the opening of a liquid guiding channel, a liquid draining channel, a liquid flowing channel, and a liquid outlet channel, and the setting of a liquid transfer component, allows the liquid guiding channel to drain the liquid inside the photovoltaic frame while the fixing column and connecting column are connecting the photovoltaic frame. The liquid flowing channel then guides the liquid to the liquid transfer pipe included in the liquid transfer component, and the liquid transfer pipe then gathers the liquid to the liquid flowing plate. Finally, the liquid guiding plate guides the liquid, allowing the liquid to be discharged from the outside of the photovoltaic frame through the liquid outlet channel, thereby improving the corrosion resistance of the photovoltaic frame.

[0013] 3. This photovoltaic frame connector, through the cooperative use of the first and second locking blocks, can position and secure the top and bottom plates included in the positioning component during the connection process between the positioning component and the L-shaped and straight frames of the photovoltaic frame. This prevents the top and bottom plates from shifting, and further prevents the locking posts and connecting posts from failing to be inserted, thereby improving the connection efficiency of the equipment. Moreover, the setting of the first and second locking blocks allows the top and bottom plates to form a whole with the L-shaped and straight frames, thereby improving the overall strength of the photovoltaic frame.

[0014] 4. This photovoltaic frame connector, through the coordinated use of a rotating rod, cam, first spring, sliding plate, connecting column, and rack plate, allows for easy disassembly of the photovoltaic frame. Applying an upward force to the connecting column causes the rack plate to drive the cam to rotate in the opposite direction, thus preventing the cam from exerting a pushing force on the push plate. Combined with the reaction force of the second spring, the reset plate drives the top plate and the retaining column downwards via the movable rod. This prevents the retaining column from securing the L-shaped frame, straight frame, and the photovoltaic modules connected to the photovoltaic frame. The photovoltaic frame can then be disassembled simply by applying a pulling force. This disassembly operation is simple and convenient, thereby improving the disassembly efficiency of the equipment.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] Reference Figures 1-10A photovoltaic frame connector includes two positioning components 1 and one connecting component 2. Each positioning component 1 includes a bidirectional telescopic component 3. A top plate 4 is fixedly connected to the top of the bidirectional telescopic component 3. A stabilizing column 5 is fixedly connected to the top of the top of the top plate 4 away from the center of the connecting component 2. A bottom plate 7 is fixedly connected to the bottom of the bidirectional telescopic component 3. The connecting component 2 includes a support plate 9. Four telescopic rods 10 are fixedly connected to the top of the support plate 9. Push plates 11 are fixedly connected to the top of two telescopic rods 10. An operating groove is formed on the top of the support plate 9. A rotating rod 12 is rotatably connected to the center of the operating groove. A cam 13 is fixedly connected to the outer surface of the rotating rod 12. Sliding grooves are formed at the front and rear ends of the operating groove away from the center of the support plate 9. A first spring 14 is fixedly connected to the bottom of the sliding groove. A sliding plate 15 is fixedly connected to the top of the first spring 14. The top of the sliding plate 15 is fixedly connected to a liquid transfer component 16, the bottom of the sliding plate 15 is fixedly connected to a connecting column 17, and the side wall of the sliding plate 15 is fixedly connected to a rack plate 18. The bidirectional telescopic component 3 includes a groove column 19, the inside of which is provided with a first sliding cavity and a second sliding cavity. The bottom of the second sliding cavity is slidably connected to a sliding rod 20. The top of the sliding rod 20 is fixedly connected to a limit plate 21, and the bottom of the sliding rod 20 is connected to the top of the bottom plate 7. The top of the first sliding cavity is fixedly connected to a second spring 22, the bottom of the second spring 22 is fixedly connected to a reset plate 23, the top of the reset plate 23 is fixedly connected to a movable rod 24, and the top of the movable rod 24 is connected to the bottom of the top plate 4. The bottom of the bottom plate 7 is provided with a through rod groove 31, the inner diameter of which is equal to the outer diameter of the connecting column 17. The side of the rack plate 18 near the center of the support plate 9 is in contact with the non-convex surface of the cam 13.

[0031] When connecting to the photovoltaic frame, the two top plates 4 and the bottom plate 7 are first placed into the L-shaped frame and the straight frame of the photovoltaic frame, respectively. Then, the two sides of the support plate 9 are placed in the middle of the two top plates 4 and the bottom plate 7. Through the reaction force of the first spring 14, the connecting post 17 passes through the through rod groove 31 and connects to the bottom of the L-shaped frame and the straight frame. After passing through the through rod groove 31, the connecting post 17 also connects to the bottom plate 7, thereby connecting the positioning component 1 and the connecting component 2. Because the rack plate 18 moves with the connecting post 17, when the connecting post 17 is connected, the rack plate 18 drives the cam 13 to rotate, thereby causing the push plate 11 to move the top plate 4 and the limiting post 5 upward. This not only connects the limiting post 5 to the top of the L-shaped frame and the straight frame, but also allows the limiting post 5 to perform the insertion and fixing work on the photovoltaic structure placed on the L-shaped frame and the straight frame, thereby improving the connection efficiency and increasing the fixation of the photovoltaic frame to the photovoltaic structure.

[0032] When disassembling the photovoltaic frame, simply apply an upward force to the connecting post 17 connected to the bottom of the L-shaped frame and the straight frame. This will cause the rack plate 18 to apply a reverse rotational force to the cam 13. Then, the reaction force of the second spring 22 will drive the retaining post 5 to separate from the L-shaped frame, the straight frame, and the photovoltaic structure. The L-shaped frame and the straight frame can then be separated by pulling outwards, thus improving disassembly efficiency.

[0033] It should be noted that one side of the cam 13 is convex, while the other side of the cam 13 is gear-shaped. The gear-shaped side of the cam 13 will contact the rack plate 18, so the cam 13 will rotate during the movement of the rack plate 18.

[0034] Reference Figures 5-7 The top plate 4 has first locking blocks 6 on both sides of its front and rear ends for engaging with the photovoltaic frame, and the bottom plate 7 has second locking blocks 8 on both sides of its front and rear ends for engaging with the photovoltaic frame. When the top plate 4 and bottom plate 7 are connected to the L-shaped frame or the straight frame, the first locking blocks 6 and the second locking blocks 8 can be used to position and secure the top plate 4 and bottom plate 7 entering the L-shaped frame or the straight frame, thereby preventing the top plate 4 and bottom plate 7 from shifting, thus improving the placement efficiency of the support plate 9 and improving the installation efficiency of the equipment.

[0035] It should be noted that horizontal grooves are provided at the top and bottom of the front and rear ends of the connected L-shaped and straight frame slots. The upper horizontal groove contacts the first locking block 6, and the lower horizontal groove contacts the second locking block 8. The top of the upper horizontal groove and the bottom of the lower horizontal groove are provided with buckle grooves that are compatible with the first locking block 6 and the second locking block 8. In this way, after the top plate 4 and the bottom plate 7 enter the L-shaped and straight frame, the first locking block 6 and the second locking block 8 can fix the position of the top plate 4 and the bottom plate 7.

[0036] Reference Figures 2-3 A column receiving groove 30 is provided on one side of the top plate 4 and the bottom plate 7. The inner diameter of the column receiving groove 30 is equal to the outer diameter of the column 19. When the positioning component 1 is retracted, the column receiving groove 30 allows the column 19 to enter the interior of the top plate 4 and the bottom plate 7. Therefore, after applying a force to move the top plate 4 and the bottom plate 7 relative to each other, the distance between the top plate 4 and the bottom plate 7 can be greatly reduced, thereby reducing the floor space occupied by the positioning component 1 and improving storage capacity.

[0037] Reference Figure 4 and Figure 10The liquid transfer assembly 16 includes a liquid-passing plate 25. A liquid guide plate 26 is fixedly connected to the bottom of the inner cavity of the liquid-passing plate 25. A liquid transfer tube 27 is fixedly connected to the top of the liquid-passing plate 25 in a circumferential array. A liquid guide groove 28 is formed around the top of the top plate 4, which is located around the retaining column 5. A drain groove 29 is formed in a circumferential array at the bottom of the liquid guide groove 28. Liquid passage grooves 32 are formed in a circumferential array on the top of both sides of the push plate 11. A connecting groove 33 is formed at the bottom of the liquid passage groove 32. The inner surface of the connecting groove 33 is connected to the outer surface of the top of the liquid transfer tube 27. A liquid outlet groove 3 is formed on both sides of the bottom of the inner cavity of the liquid-passing plate 25 and on both sides of the top of the connecting column 17. 4. After liquid enters the photovoltaic frame, the liquid guide trough 28 can guide the liquid to the drain trough 29 through its inclined side. Then, the liquid is discharged through the liquid passage trough 32 to the liquid transmission pipe 27 connected to the connecting trough 33. The liquid transmission pipe 27 then guides the liquid into the liquid passage plate 25. The liquid is then guided through the liquid guide plate 26 to the outlet trough 34. Finally, the liquid is discharged through the outlet trough 34. Because the connecting column 17 is located on the outside of the bottom side of the photovoltaic frame, the liquid discharged from the outlet trough 34 will not come into contact with the photovoltaic frame, thereby improving the corrosion resistance of the photovoltaic frame.

[0038] It should be noted that the liquid transfer pipe 27 is a corrugated culvert, which has a certain degree of elasticity. Therefore, during the lifting and lowering movement of the push plate 11, the liquid transfer pipe 27 can remain connected to the push plate 11. The continuously connected liquid transfer pipe 27 can prevent the liquid from moving to other positions due to the tilt of the photovoltaic frame during the liquid guiding process. The inclined sides of the liquid guiding plate 26 can quickly guide the liquid to the liquid outlet 34 when the photovoltaic frame is in a flat position, and can also quickly guide the liquid to the liquid outlet 34 when the photovoltaic frame is in an inclined position.

[0039] The working principle and usage of this invention are explained in detail below: When connecting the L-shaped and straight frames of the photovoltaic frame, the first locking block 6 and the second locking block 8 connected to the top plate 4 and bottom plate 7 of a positioning component 1 are first inserted into the interior of the L-shaped frame. Then, a pushing force is applied to the top plate 4, causing the first locking block 6 and the second locking block 8 to fully enter the interior of the L-shaped frame. After the top plate 4 moves a certain distance, there will be a gap below the second locking block 8, which can then move downwards under the weight of the bottom plate 7 and the second locking block 8, thereby securing the bottom plate 7, the bidirectional telescopic component 3, and the top plate 4 inside the L-shaped frame. Then, one side of the support plate 9 is placed between the top plate 4 and the bottom plate 7, and a pushing force is applied to the support plate 9, causing one side of the support plate 9 to enter the interior of the L-shaped frame. After the support plate 9 moves a certain distance, the connecting post 17 will be positioned above the through-rod slot 31 opened in the bottom plate 7. When the first spring 14's reaction force causes the sliding plate 15, rack plate 18, and connecting post 17 to move downwards, the downward-moving connecting post 17 passes through the bottom plate 7 and connects to the bottom of the L-shaped frame. The downward-moving rack plate 18 causes the cam 13 to rotate, thereby generating an upward thrust on the push plate 11. This allows the push plate 11 to move upwards along with the top plate 4 and the retaining post 5, enabling the retaining post 5 to be inserted and fixedly connected to the top of the L-shaped frame and the photovoltaic module at the L-shaped frame. Then, the first locking block 6 and the second locking block 8 connected to the top plate 4 and bottom plate 7 of the other positioning component 1 are inserted into the interior of the straight frame. Then, according to the above installation method, the bottom plate 7, the bidirectional telescopic component 3, and the top plate 4 are fixed inside the straight frame. Then, the other side of the support plate 9 is placed in the center of the top plate 4 and the bottom plate 7. Finally, according to the above installation method, the other positioning component 1 is connected to the connecting component 2 and the straight frame.

[0040] It is important to note that after the user assembles the L-shaped frame and the straight frame into a C-shaped frame using the connection method described above, the assembly of the C-shaped frame should be stopped. Then, another C-shaped frame needs to be assembled and installed. This C-shaped frame is then connected to the two straight frame frames using the same connection method. Finally, this C-shaped frame is connected to the unassembled C-shaped frame. At this point, an upward force needs to be applied to the connecting post 17 at the bottom of the unassembled C-shaped frame, causing the connecting post 17 to move upward along with the rack plate 18. This will cause the rack plate 18 to... 8. Applying a rotational force to the cam 13, thereby preventing the cam 13 from applying a pushing force to the push plate 11, and then allowing the second spring 22 to drive the reset plate 23, along with the movable rod 24, the top plate 4, and the retaining post 5, to move downwards through the reaction force. Thus, during the connection between the C-shaped frame and the unassembled C-shaped frame, the retaining post 5 of the unassembled C-shaped frame will not affect the photovoltaic module. After the connection is completed, the force applied to the connecting post 17 can be removed, and then the retaining post 5 of the unassembled C-shaped frame can be used to secure the photovoltaic module.

[0041] It should be noted that when the connected photovoltaic frame is immersed in liquid, the liquid will enter the interior of the drain tank 29 through the liquid guide trough 28. Then, the liquid can be transferred to the liquid transmission pipe 27 through the liquid passage trough 32 opened by the push plate 11. The liquid transmission pipe 27 then guides the liquid into the interior of the liquid passage plate 25. Then, through the liquid guide plate 26, the liquid inside the liquid passage plate 25 is directed to the liquid outlet troughs 34 on both sides. Finally, the liquid is discharged to the outside of the photovoltaic frame through the liquid outlet troughs 34, thereby preventing the liquid from corroding the photovoltaic frame.

[0042] When the equipment is disassembling the complete photovoltaic frame, an upward force needs to be applied to the connecting post 17 of one of the C-shaped frames. Then, the entire C-shaped frame can be removed by applying a pulling force. Then, a pushing force can be applied to one of the connecting posts 17 individually to perform the disassembly work.

[0043] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
