Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel accessories technology, specifically to an adjustable side pressure photovoltaic panel component. Background Technology

[0002] With the rapid development of my country's economy, energy demand continues to rise. The large-scale use of traditional fossil fuels (such as coal, oil, and natural gas) not only faces the problem of resource depletion but also leads to serious environmental pollution. The rise of new energy sources has gradually replaced a large amount of fossil fuels, and solar power generation constitutes an important part of this new energy landscape. Currently, most solar power generation is achieved by using sunlight to power solar panels, leading to increased market demand for photovoltaic panels.

[0003] Existing photovoltaic (PV) panels require clamping blocks for installation. For example, Chinese patent document CN221728193U discloses a single-sided first clamping block assembly and a PV panel assembly. The single-sided first clamping block assembly includes a saddle lock, a locking member, and a first clamping block. The saddle lock has a locking groove for engaging one end of the PV panel, with the groove opening facing the saddle lock. The locking member extends through the saddle lock, its extension direction perpendicular to the opening of the locking groove. The first clamping block is located below the saddle lock, and the lower end of the locking member is threaded to the first clamping block. A crossbeam limiting gap is reserved between the first clamping block and the lower end of the saddle lock. The inner surface of the locking groove has a rubber structure. The PV panel is installed by clamping it into the locking groove of the saddle lock. However, this structure is only suitable for PV panels whose height matches the locking groove. If the thickness or size of the photovoltaic panel is different, it may not be able to be effectively fixed, and the snap-fit ​​groove needs to be redesigned. This has poor versatility. In addition, the snap-fit ​​groove is connected to the photovoltaic panel through a rubber structure. When the rubber material is exposed to the natural environment for a long time, it may age. The aged rubber will become hard and brittle, resulting in a decrease in its friction and elasticity, thus affecting the fixing effect of the photovoltaic panel. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable side pressure photovoltaic panel component, which is suitable for fixed installation of photovoltaic panels of different thicknesses and has high versatility.

[0005] The technical solution adopted by the adjustable side-pressure photovoltaic panel disclosed in this utility model is:

[0006] An adjustable side-pressure photovoltaic panel assembly includes a first pressure block, a locking member, and a slider. The slider is disposed within a guide rail. The first pressure block is connected to the slider via the locking member. The assembly also includes a second pressure block disposed on the guide rail. One side of the first pressure block has a snap-fit ​​portion with snap teeth arranged axially along its side. One side of the second pressure block has a slot that matches the snap teeth. The snap teeth on the snap-fit ​​portion can selectively engage with the slot of the second pressure block. When the locking member fixes the first and second pressure blocks to the guide rail, the sidewalls of the first and second pressure blocks form a snap-fit ​​groove, which is used to fix the photovoltaic panel above the guide rail.

[0007] As a preferred embodiment, a pressing part is provided on the other side of the first pressing block, and anti-slip teeth are provided at the bottom of the pressing part, the anti-slip teeth abutting against the top surface of the photovoltaic panel.

[0008] As a preferred embodiment, a connecting block is provided between the pressing part and the snap-fit ​​part, the head of the locking member is located inside the connecting block, and the height of the connecting block is lower than the height of the pressing part and the snap-fit ​​part.

[0009] As a preferred embodiment, the bottom of the second pressing block is provided with a retaining edge, which is used to abut against the side surface of the photovoltaic panel, and the edge of the pressing part extends beyond the edge of the retaining edge.

[0010] As a preferred embodiment, the locking part has a missing tooth portion between the locking teeth, and the number of locking teeth below the missing tooth portion is greater than the number of locking teeth above the missing tooth portion.

[0011] As a preferred embodiment, the tooth has an abutting surface and an inclined surface, and a rounded corner is provided between the abutting surface and the inclined surface. The abutting surface is located at the bottom end of the tooth.

[0012] As a preferred embodiment, the slot is provided with a support surface and a contact surface. When the card tooth engages with the slot, the support surface abuts against the contact surface, and the inclined surface abuts against the contact surface.

[0013] As a preferred embodiment, the contact surface and the supporting surface are rough planes.

[0014] As a preferred embodiment, the first pressure block and the second pressure block have mounting holes for accommodating a locking member in the middle. The locking member passes through the mounting holes of the first pressure block and the second pressure block and is threadedly connected to the slider. A spring washer is provided between the locking member and the first pressure block.

[0015] As a preferred embodiment, the slider is capable of moving along the inner cavity of the guide rail, and the two side surfaces of the slider are provided with serrated stripes that cooperate with the inner side of the guide rail.

[0016] The beneficial effects of this utility model's adjustable side-pressure photovoltaic panel assembly are as follows: During photovoltaic panel installation, the engagement between the teeth of the first pressure block and the slots of the second pressure block can be flexibly adjusted according to the thickness of the photovoltaic panel. Subsequently, the first and second pressure blocks are placed on a guide rail, allowing the locking element to pass through them sequentially and connect threadedly to a slider located within the guide rail's inner cavity. At this point, the photovoltaic panel can be smoothly installed into the engagement groove formed by the first and second pressure blocks. Finally, the locking element is tightened, ensuring the first pressure block is firmly pressed against the upper surface of the photovoltaic panel, while simultaneously ensuring the second pressure block is securely pressed against the guide rail. By utilizing the engagement between the teeth of the first pressure block and the slots at different positions on the second pressure block, the relative positions of the first and second pressure blocks can be flexibly adjusted, thus adapting to photovoltaic panels of different thicknesses and sizes, making the installation process simpler, more convenient, and more versatile.

[0021] An adjustable side-pressure photovoltaic panel assembly includes a first pressure block, a locking member, and a slider. The slider is disposed within a guide rail. The first pressure block is connected to the slider via the locking member. The assembly also includes a second pressure block disposed on the guide rail. One side of the first pressure block has a snap-fit ​​portion with snap teeth arranged axially along its side. One side of the second pressure block has a slot that matches the snap teeth. The snap teeth on the snap-fit ​​portion can selectively engage with the slot of the second pressure block. When the locking member fixes the first and second pressure blocks to the guide rail, the sidewalls of the first and second pressure blocks form a snap-fit ​​groove, which is used to fix the photovoltaic panel above the guide rail.

[0022] When installing photovoltaic panels, the engagement between the teeth of the first pressure block and the slots of the second pressure block can be flexibly adjusted according to the thickness of the photovoltaic panel. Then, the first and second pressure blocks are placed on the guide rail, allowing the locking element to pass through them sequentially and connect threadedly to the slider located within the guide rail cavity. At this point, the photovoltaic panel can be smoothly installed into the engagement groove formed by the first and second pressure blocks. Finally, the locking element is tightened to ensure the first pressure block is firmly pressed against the upper surface of the photovoltaic panel, while simultaneously ensuring the second pressure block is securely pressed against the guide rail. By utilizing the engagement between the teeth of the first pressure block and the slots at different positions on the second pressure block, the relative positions of the first and second pressure blocks can be flexibly adjusted, thus accommodating photovoltaic panels of different thicknesses and sizes, making the installation process simpler, more convenient, and highly versatile.

[0023] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0024] Please refer to Figures 1 to 4 An adjustable side-pressure photovoltaic panel assembly includes a first pressure block 10, a locking member 20, a slider 30, and a second pressure block 40. The slider 30 is embedded in a cavity of a guide rail 50. The first pressure block 10 and the second pressure block 40 have mounting holes in their middle sections to accommodate the locking member 20. The locking member 20 passes through the mounting holes of the first pressure block 10 and the second pressure block 40 and is threadedly connected to the slider 30. The first pressure block 10 and the second pressure block 40 are positioned above the guide rail 50, and the locking member 20 securely locks the first pressure block 10 and the second pressure block 40 onto the guide rail 50. The locking member 20 is a fixing bolt with a countersunk hexagonal head, allowing for assembly by replacing different bolts as needed.

[0025] The first pressure block 10 is provided with a snap-fit ​​part 11, a pressing part 12, and a connecting block 13. The snap-fit ​​part 11 is located at one end of the connecting block 13. The snap-fit ​​part 11 has a plurality of snap teeth 111 arranged axially. In this embodiment, the snap teeth 111 are triangular snap teeth 111, which are arranged along the lateral width of the snap-fit ​​part 11. A toothed portion 112 is formed between adjacent snap teeth 111. The number of snap teeth 111 below the toothed portion 112 is greater than the number of snap teeth 111 above the toothed portion 112. The difference in the distribution of the snap teeth 111 provides more stable support when subjected to force.

[0026] A spring washer 60 is provided between the locking member 20 and the first pressure block 10 to prevent the locking member 20 from loosening due to vibration or external force during long-term use, which can effectively improve the reliability and stability of the photovoltaic panel adjustable side pressure module.

[0027] The clamping part 12 is located at the other end of the connecting block 13. The bottom of the clamping part 12 is provided with anti-slip teeth 121, which abut against the top surface of the photovoltaic panel. The anti-slip teeth 121 can increase friction and prevent the photovoltaic panel from sliding during installation and use, thereby firmly pressing the photovoltaic panel onto the guide rail 50. The shape of the anti-slip teeth 121 can be designed as serrated, wavy, or other shapes to achieve the same effect.

[0028] The locking member 20 includes a head and a rod. The head of the locking member 20 cooperates with the connecting block 13 of the first pressure block 10. The rod of the locking member 20 passes through the mounting holes of the first pressure block 10 and the second pressure block 40 and is screwed to the slider 30. The connecting block 13 has a smooth surface for placing the head of the locking member 20. The height of the connecting block 13 is lower than the height of the pressing part 12 and the snap-fit ​​part 11. When the head of the locking member 20 is twisted, the movement of the head of the locking member 20 between the snap-fit ​​part 11 and the pressing part 12 is restricted, so as to avoid the head of the locking member 20 interfering with the photovoltaic panel.

[0029] The second pressing block 40 has a slot 41 on one side that matches the teeth 111. The slot 41 is triangular, so that the teeth 111 of the first pressing block 10 can fit tightly with the slot 41 of the second pressing block 40. The slot 41 is set along the horizontal width of the second pressing block 40 and is arranged in the same way as the teeth 111 of the first pressing block 10, ensuring that the two can match perfectly. The bottom of the second pressing block 40 is also provided with a baffle 42, which plays a preliminary positioning role and is used to hold the side of the photovoltaic panel, thereby restricting the vertical movement of the photovoltaic panel and ensuring that the photovoltaic panel will not be laterally displaced after installation. The edge of the pressing part 12 extends beyond the edge of the baffle 42, so that the pressing part 12 can better cover the top surface of the photovoltaic panel and work together with the baffle 42 to fix the photovoltaic panel from both the top and side directions.

[0030] In another embodiment, the locking teeth 111 on the first pressing block 10 are dovetail blocks, and the locking groove 41 of the second pressing block 40 is a dovetail groove. When the first pressing block 10 and the second pressing block 40 cooperate, they can also play the role of fixing the photovoltaic panel.

[0031] The locking tooth 111 has an abutment surface 112 and an inclined surface 113, with the abutment surface 112 located at the bottom end of the locking tooth 111. The slot 41 has a support surface 43 and a contact surface 44. When the locking tooth 111 engages with the slot 41, the support surface 43 abuts against the abutment surface 112, providing vertical support to the abutment surface 112 and ensuring that the locking tooth 111 is securely fixed within the slot 41. The inclined surface 113 abuts against the contact surface 44, which provides horizontal constraint to prevent the locking tooth 111 from sliding within the slot 41. The abutment surface 112 and the support surface 43 are rough planes, which can increase the friction between the locking tooth 111 and the slot 41, further improving the fixing effect.

[0032] In another embodiment, an elastic material (such as rubber or silicone) is added to the mating surfaces of the locking teeth 111 and the slots 41 to reduce loosening caused by dimensional errors.

[0033] The transition edge between the contact surface 112 and the inclined surface 113 of the locking tooth 111 is provided with rounded corners, and the transition between the support surface 43 and the contact surface 44 of the locking groove 41 is also provided with rounded corners. When the locking tooth 111 and the locking groove 41 are engaged, stress concentration can be reduced, the durability of the locking tooth 111 can be improved, and friction and wear during installation can also be reduced.

[0034] The slider 30 can move along the inner cavity of the guide rail 50, and the two side surfaces of the slider 30 are provided with serrated stripes 31 that cooperate with the inner side of the guide rail 50. When the locking member 20 is screwed to the slider 30, tightening the locking member 20 can make the slider 30 move upward to cooperate with the raised edge of the guide rail 50, so that the first pressure block 10 and the second pressure block 40 are firmly installed above the guide rail 50.

[0035] The assembly process of an adjustable side-pressure photovoltaic module involves placing a second pressure block 40 on a guide rail 50, with the flange 42 abutting against the side of the photovoltaic panel. First, the first pressure block 10 is moved up and down, and a suitable position for the locking teeth 111 is selected. The first pressure block 10 is then installed into the side of the second pressure block 40, so that the locking teeth 111 on the locking part 11 of the first pressure block 10 engage with the locking groove 41 of the second pressure block 40. The sidewalls of the first and second pressure blocks form a locking groove adapted to the thickness of the photovoltaic panel being installed. Then, a locking member 20 is inserted into the mounting hole of the first pressure block 10, passing through the second pressure block 40, and screwed onto a slider 30 located within the inner cavity of the guide rail 50. Finally, the locking member 20 is tightened, causing the anti-slip teeth 121 of the first pressure block 10 to engage. The top surface of the photovoltaic panel is pressed down, while the baffle 42 of the second pressing block 40 restricts lateral displacement. Through the cooperation of the baffle 42, the locking teeth 111 and the locking groove 41, and the pressing of the anti-slip teeth 121, the adjustable side-pressing module of the photovoltaic panel can fix the photovoltaic panel from multiple directions, which significantly improves the stability of the photovoltaic panel. Moreover, the meshing design of the locking teeth 111 and the locking groove 41 allows for adjustment according to the user's needs, which can adapt to photovoltaic panels of different thicknesses and increase the versatility of the adjustable side-pressing module of the photovoltaic panel. The opening size of the locking groove of the adjustable side-pressing module of the photovoltaic panel can be adjusted by simply adjusting the meshing cooperation between the first pressing block 10 and the second pressing block 40, and the installation can be completed by tightening the locking part 20. The operation is simple and convenient, and the installation efficiency is high.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
