Description

Technical Field

[0001] This utility model relates to a wide range of applications, specifically a frame for a photovoltaic module mounting bracket. Background Technology

[0002] Lightweight photovoltaic (PV) modules offer advantages such as light weight and flexibility, allowing them to be easily attached to building exteriors like roofs, corrugated steel sheets, and walls using structural adhesive. However, when installing PV modules on corrugated steel sheets, the traditional method involves applying structural adhesive with a caulking gun to the raised edges of the sheet before placing the module on top, bonding the back of the module to the adhesive-coated edges. While simple and convenient, this method becomes problematic when the corrugated steel roof requires renovation or replacement. The traditional method, which integrates the module and sheet, makes separation difficult and prone to damage. Furthermore, the uneven structure of the corrugated steel sheet leaves some lightweight PV modules suspended, increasing their susceptibility to deformation under prolonged unsupported conditions, impacting power generation efficiency and lifespan.

[0003] A Chinese patent discloses a frame and mounting bracket for a lightweight photovoltaic module (authorization announcement number CN119945292 A). This patent provides a convenient and structurally stable mounting bracket for lightweight photovoltaic modules. However, it extensively uses disposable fixing materials such as adhesives. While this may simplify installation, it can damage or corrode the photovoltaic modules during disassembly. Furthermore, due to the fixed connection and lack of shock absorption for the photovoltaic modules, the photovoltaic panels may be damaged even by minor external forces. Therefore, those skilled in the art have developed a photovoltaic module mounting bracket frame to address the problems described in the background. Utility Model Content

[0004] The purpose of this utility model is to provide a frame for a photovoltaic module mounting bracket to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A photovoltaic module mounting bracket frame includes a frame body, which includes several clamping components. The clamping components are connected to the frame body and the clamping components by screws and fixing screw grooves, i.e., the frame body and the clamping components are fixedly connected. The clamping components include a lower base plate and a side base plate. A movable rack is provided in the middle of the side base plate. The edge of the side base plate is slidably connected to a movable module. The movable rack meshes with a movable gear. The movable gear is fixedly connected to a drive shaft. The drive shaft is clearance-fitted with a shaft hole provided on the movable module. The left side of the drive shaft is fixedly connected to an opening and closing control component. The lower part of the movable module is fixedly connected to an upper engagement plate.

[0007] Preferably, the upper biting plate is provided with a contact pad, the moving module is provided with a first biting piece on the side away from the side bottom plate, the lower bottom plate is provided with several buffer devices above it, the lower bottom plate is provided with a second biting piece on the side away from the side bottom plate, the top of the buffer device is fixedly connected to the lower biting plate, and the lower biting plate is also provided with a contact pad above it. When the edge of the photovoltaic module is placed above the lower biting plate, since the opening and closing control component is fixedly connected to the transmission shaft and the moving gear, the rotation of the opening and closing control component will drive the moving gear to rotate and make it move relative to the moving rack. In general, the moving module moves up and down relative to the lower biting plate. Rotating the opening and closing control component makes the moving module move closer to the lower biting plate, so that the edge of the photovoltaic module is fixed between the upper biting plate and the lower biting plate. The biting piece is used to further strengthen the biting force and make the photovoltaic module less likely to detach. When the clamping component completes the biting, the clamping component can be installed on the frame body by using screws and bolts to connect with the fixed screw groove. The photovoltaic module is surrounded by four frame bodies to form the bracket frame.

[0008] Preferably, the buffer device includes a base, which is fixedly connected to the bottom of the device shell, the outer cavity partition, and the inner cavity partition. The inner layer of the device shell is the outer cavity partition, and the inner layer of the outer cavity partition is the inner cavity partition. The cavity between the outer cavity partition and the inner cavity partition is the outer cavity, and the cavity inside the inner cavity partition is the inner cavity. The inner cavity is equipped with a spring, the inner cavity partition has an oil outlet hole, and the top of the inner cavity partition has an oil return hole. The top of the spring is fixedly connected to a piston, the upper end of the piston is fixedly connected to a rod, the top of the rod is fixedly connected to a flexible contact plate, the flexible contact plate is fixedly connected to the outer cavity partition, and the rod is surrounded by a stamped... The plate has several layers of pressure-accumulating sponge above the outer cavity partition. When subjected to pressure from the photovoltaic module, the flexible contact plate will slightly contract and transmit the pressure downward. The hydraulic oil in the inner cavity, after being pressurized, will be discharged from the oil outlet into the outer cavity, and then return to the inner cavity of the upper half of the piston through the oil return hole. In this process, the kinetic energy is converted into internal energy and released. The spring then rebounds, restoring the buffer device. The pressure-accumulating sponge can accumulate instantaneous pressure and release it slowly, which can more effectively protect the tissue structure. The main function of the buffer device is to buffer the pressure that the surface of the photovoltaic module may be subjected to and the negative impact caused by excessive pressure from the moving module.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. This utility model avoids the use of glue, a disposable fixing material, and instead adopts a pressing fixing method. Firstly, it is still easy to install and can be installed without additional materials. Secondly, it facilitates the disassembly of the structure, and the photovoltaic module will not be damaged or corroded due to the fixing connection of this new model.

[0011] 2. This utility model incorporates a buffer device, which effectively reduces damage to the photovoltaic module when it faces surface blunt impact, thereby extending the service life of the photovoltaic module and this utility model. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5 In this embodiment of the present invention, a photovoltaic module mounting bracket frame includes a frame body 15. The frame body 15 includes a plurality of clamping members 1. The clamping members 1 are bolted to the frame body 15 and the clamping members 1 through fixing screw grooves 13, i.e., the frame body 15 and the clamping members 1 are fixedly connected. The clamping members 1 include a lower base plate 8 and a side base plate 14. A movable rack 5 is provided in the middle of the side base plate 14. The edge of the side base plate 14 is slidably connected to a movable module 10. The movable rack 5 meshes with a movable gear 6, and the movable gear 6 is connected to a transmission shaft 11. The transmission shaft 11 is fixedly connected to the shaft hole provided on the moving module 10 with clearance fit. The left side of the transmission shaft 11 is fixedly connected to the opening and closing control component 12. The lower part of the moving module 10 is fixedly connected to the upper biting plate 2. The upper biting plate 2 is provided with a contact soft pad 4. The side of the moving module 10 away from the side bottom plate 14 is provided with a first biting piece 9. Several buffer devices 3 are provided above the lower bottom plate 8. The side of the lower bottom plate 8 away from the side bottom plate 14 is provided with a second biting piece 91. The top of the buffer device 3 is fixedly connected to the lower biting plate 7. The lower biting plate 7 is also provided with a contact soft pad 4 above it.

[0020] The buffer device 3 includes a base 311, which is fixedly connected to the bottom of the device housing 312, the outer cavity partition 313, and the inner cavity partition 314. The inner layer of the device housing 312 is the outer cavity partition 313, and the inner layer of the outer cavity partition 313 is the inner cavity partition 314. The cavity between the outer cavity partition 313 and the inner cavity partition 314 is the outer cavity, and the cavity inside the inner cavity partition 314 is the inner cavity. The inner cavity is provided with a spring 315, and the inner cavity partition 314 is provided with... There is an oil outlet 316, and the top of the inner cavity partition 314 is provided with an oil return hole 317. The top of the spring 315 is fixedly connected to the piston 318. The upper end of the piston 318 is fixedly connected to the rod 319. The top end of the rod 319 is fixedly connected to the flexible contact plate 320. The flexible contact plate 320 is fixedly connected to the outer cavity partition 313. The rod 319 is surrounded by a stamping plate 321. Several layers of pressure accumulating sponge 322 are provided above the outer cavity partition 313.

[0021] The working principle of this utility model is as follows: The edge of the photovoltaic module is placed above the lower biting plate 7. Since the opening and closing control component 12 is fixedly connected to the transmission shaft 11 and the moving gear 6, the rotation of the opening and closing control component 12 will drive the moving gear 6 to rotate and make it move relative to the moving rack 5. In general, the moving module 10 moves up and down relative to the lower biting plate 7. Rotating the opening and closing control component 12 makes the moving module 10 move closer to the lower biting plate 7, so that the edge of the photovoltaic module is fixed between the upper biting plate 2 and the lower biting plate 7. The biting piece is made of flexible material, which increases the friction between the photovoltaic module and the clamping component 1, making it difficult for the photovoltaic module to detach. When the clamping component 1 completes the biting, the clamping component 1 can be installed on the frame body 15 by using screws and bolts connected to the fixing screw groove 13. The photovoltaic module is surrounded by four frame bodies 15 to form the bracket frame.

[0022] When subjected to pressure from the photovoltaic module, the flexible contact plate 320 will slightly contract and transmit the pressure downward. The hydraulic oil in the inner cavity, after being pressurized, will be discharged from the oil outlet 316 into the outer cavity, and then return to the inner cavity of the upper half of the piston 318 through the oil return hole 317. In this process, the kinetic energy is converted into internal energy and released. The spring 315 then rebounds, allowing the buffer device 3 to recover. The pressure accumulating sponge 322 can accumulate the instantaneous pressure and release it slowly, which can more effectively protect the structure. The main function of the buffer device 3 is to buffer the pressure that the surface of the photovoltaic module may be subjected to and the negative impact caused by the excessive pressure of the moving module 10.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
