Description

Technical Field

[0001] This utility model relates to the field of crystalline silicon photovoltaic tile technology, specifically a frame-locking crystalline silicon photovoltaic tile. Background Technology

[0002] As a clean and renewable energy solution, photovoltaic power generation is gradually becoming an important force in the energy sector. With the rapid development of the photovoltaic industry, photovoltaic tiles, as an innovative product that combines photovoltaic power generation with building materials, can directly replace traditional roof tiles, achieving a perfect integration of buildings and photovoltaics. While providing green electricity for buildings, they can also enhance the aesthetic value and energy efficiency of buildings.

[0003] In the prior art, Chinese patent CN211286344U discloses a new type of photovoltaic tile, including a first photovoltaic tile and a sloping roof. The top of the sloping roof is fixedly connected with purlins. The top of the first photovoltaic tile has stepped holes with screws installed inside. A second photovoltaic tile overlaps the bottom of one side of the first photovoltaic tile. A right frame is provided on one side of the first photovoltaic tile. The right and left frames provide waterproofing, dustproofing, and protection against debris accumulation. Flat photovoltaic panels are generally large in size, while the flat photovoltaic panels in the new photovoltaic tile are small in size, allowing for full coverage of the roof and maximizing the use of the roof space. The photovoltaic tile does not require additional photovoltaic supports; it is directly connected to the roof, achieving building-integrated photovoltaics. The photovoltaic tile is not used as a load-bearing component but mainly serves for power generation, thermal insulation, waterproofing, and decoration.

[0004] Based on the above information, it can be seen that in the existing technology, photovoltaic tiles are usually fixedly connected to the frame. When a single photovoltaic tile is damaged and needs to be replaced, the frame must often be replaced as well. Furthermore, the ends of the frame are mostly fixed to the frame with bolts, which further increases the inconvenience of maintenance and replacement. Therefore, we propose a frame-clamping crystalline silicon photovoltaic tile. Utility Model Content

[0005] The purpose of this utility model is to provide a frame-locking crystalline silicon photovoltaic tile to solve the problem mentioned in the background art that in the prior art, the photovoltaic tile is usually fixedly connected to the frame, which means that when a single photovoltaic tile is damaged and needs to be replaced, the frame must often be replaced together; and the end of the frame is mostly fixed to the frame with bolts, which further increases the inconvenience of maintenance and replacement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a frame-mounted snap-on crystalline silicon photovoltaic tile, comprising a photovoltaic tile body and a side frame, wherein an installation groove is provided on the inner wall of the side frame, and the photovoltaic tile body and the side frame are slidably connected through the installation groove; the end of the side frame is provided with a snap-fit ​​structure for convenient assembly and disassembly of the photovoltaic tile body, the snap-fit ​​structure including a fixed top frame provided at the end of the side frame, and a snap-fit ​​block provided at the end of the fixed top frame, and a protrusion provided on the outer wall of the snap-fit ​​block; the outer wall of the side frame and the outer wall of the fixed top frame are provided with an overlapping structure for overlapping the photovoltaic tile body.

[0007] Furthermore, the side frame has a U-shaped cross-section, the mounting groove is adapted to the edge of the photovoltaic tile body, and a sealing structure is provided between the inner wall of the mounting groove and the photovoltaic tile body.

[0008] Furthermore, the fixed top frame is adapted to the opening end of the side frame, the end of the side frame is provided with a sealing gasket, and the outer walls of the sealing gasket on both sides of the photovoltaic tile body abut against the fixed top frame and the side frame respectively when the photovoltaic tile body is in the snap-fit ​​state.

[0009] Furthermore, two sets of the snap-fit ​​blocks are symmetrically arranged on the side of the fixed top frame close to the side frame, and the snap-fit ​​blocks are made of elastic material. The protrusion is located on the side of the snap-fit ​​block away from the photovoltaic tile body, and the end of the protrusion away from the fixed top frame is designed with an inclined surface.

[0010] Furthermore, two sets of snap-fit ​​grooves are symmetrically provided at the end of the side frame, and the snap-fit ​​grooves are adapted to the snap-fit ​​blocks and protrusions. The outer wall of the side frame is provided with a through hole, and the through hole is connected to the snap-fit ​​groove. In the snap-fit ​​state, the protrusion of the fixed top frame and the side frame is located in the through hole.

[0011] Furthermore, the overlapping structure includes a skeleton slot opened at the bottom of the fixed top frame, and the inner wall of the skeleton slot is provided with a buffer pad. The outer walls on both sides of the side frame are respectively provided with overlapping blocks and overlapping grooves, and the outer surface of the fixed top frame is provided with a flange.

[0012] Furthermore, the frame slot is a through slot that passes through the bottom of the fixed top frame, and the frame slot is compatible with the roof frame. The buffer pad is made of rubber, and the outer wall of the buffer pad has anti-slip texture, and the outer wall of the buffer pad is in contact with the outer wall of the frame.

[0013] Furthermore, the overlapping block is arranged along the length of the side frame, and the outer surface of the overlapping block is flush with the outer surface of the side frame. The cross-section of the overlapping block is L-shaped. The overlapping groove is adapted to the overlapping block. The outer surface of the fixed top frame and the bottom end of the side frame are both provided with flanges, and the bottom flange of the side frame overlaps with the top flange of the adjacent fixed top frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This snap-fit ​​crystalline silicon photovoltaic tile uses a sliding groove on the inner wall of the side frame to achieve a sliding connection with the photovoltaic tile body. Combined with the snap-fit ​​structure at the end of the side frame, it solves the replacement problem caused by the fixed connection between the photovoltaic tile and the frame in traditional photovoltaic tiles. When a single photovoltaic tile body is damaged, there is no need to remove the side frame. Only the snap-fit ​​of the fixed top frame needs to be released to pull the photovoltaic tile body out of the installation groove for replacement. This greatly reduces maintenance costs and operational complexity, and avoids the waste of resources that requires replacing the frame when replacing the tile in traditional technology.

[0015] 2. By setting up a snap-fit ​​structure, both ease of installation and waterproof sealing are taken into account; the snap-fit ​​block of the fixed top frame and the snap-fit ​​groove of the side frame can be quickly assembled through the protrusion without the need for bolt tightening; at the same time, the sealing gasket at the end of the side frame tightly abuts against the fixed top frame and the side frame in the snap-fit ​​state, and together with the sealing structure in the installation groove, a double waterproof barrier is formed, which effectively prevents rainwater from seeping into the connection gap between the photovoltaic tile body and the frame.

[0016] 3. The overlapping structure enables stable adaptation of multiple components and full roof coverage; the frame slot at the bottom of the fixed top frame can be precisely connected with the roof frame, and the anti-slip texture of the buffer pad can enhance the friction between the frame and the frame, preventing the photovoltaic tiles from shifting under the influence of the roof slope; the overlapping design between the overlapping blocks, overlapping grooves and flanges of the side frame allows multiple photovoltaic tiles to be seamlessly spliced, which not only ensures the integrity of the roof coverage, but also further enhances the wind load resistance of the overall structure through the cooperation of the L-shaped overlapping blocks and flanges.

[0019] 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.

[0020] Example 1: Please refer to Figures 1-6 The present invention provides the following technical solution: a frame-locking crystalline silicon photovoltaic tile, comprising a photovoltaic tile body 1 and a side frame 2, wherein an installation groove 4 is provided on the inner wall of the side frame 2, and the photovoltaic tile body 1 and the side frame 2 are slidably connected through the installation groove 4. The end of the side frame 2 is provided with a locking structure for convenient disassembly and assembly of the photovoltaic tile body 1. The locking structure includes a fixed top frame 3 provided at the end of the side frame 2, and a locking block 7 is provided at the end of the fixed top frame 3, and a protrusion 701 is provided on the outer wall of the locking block 7.

[0021] like Figures 1-6 As shown, the side frame 2 has a U-shaped cross-section. The mounting groove 4 is adapted to the edge of the photovoltaic tile body 1, and a sealing structure is provided between the inner wall of the mounting groove 4 and the photovoltaic tile body 1. The fixed top frame 3 is adapted to the opening end of the side frame 2. The end of the side frame 2 is provided with a sealing gasket 8, and the outer walls on both sides of the sealing gasket 8 abut against the fixed top frame 3 and the side frame 2 respectively when the photovoltaic tile body 1 is in the snap-fit ​​state.

[0022] like Figures 3-6 As shown, two sets of snap-fit ​​blocks 7 are symmetrically arranged on the side of the fixed top frame 3 close to the side frame 2. The snap-fit ​​blocks 7 are made of elastic material. The protrusion 701 is located on the side of the snap-fit ​​block 7 away from the photovoltaic tile body 1, and the end of the protrusion 701 away from the fixed top frame 3 is designed with a bevel. Two sets of snap-fit ​​grooves 203 are symmetrically opened at the end of the side frame 2. The snap-fit ​​grooves 203 are adapted to the snap-fit ​​blocks 7 and the protrusions 701. The outer wall of the side frame 2 is provided with a through hole 204, and the through hole 204 is connected to the snap-fit ​​groove 203. When the fixed top frame 3 and the side frame 2 are snapped together, the protrusion 701 is located in the through hole 204.

[0023] During installation, align the snap-fit ​​block 7 of the fixed top frame 3 with the snap-fit ​​groove 203 at the end of the side frame 2, and apply a pushing force to insert the snap-fit ​​block 7 into the snap-fit ​​groove 203. Due to its inclined design, the protrusion 701 guides the snap-fit ​​block 7 smoothly into the groove. During the process, the snap-fit ​​block 7 is squeezed by the groove wall and undergoes a slight elastic deformation. When the protrusion 701 moves to the position of the through hole 204 on the outer wall of the side frame 2, the deformation resets and the protrusion 701 is embedded in the through hole 204, forming a mechanical lock. At this time, the sealing gasket 8 at the end of the side frame 2 is clamped by the fixed top frame 3 and the side frame 2, achieving the first seal. At the same time, the edge of the photovoltaic tile body 1 is tightly fitted with the sealing structure of the inner wall of the mounting slide 4, forming the second seal. During disassembly, press the protrusion 701 inward through the through hole 204 to force the snap-fit ​​block 7 to deform again and disengage from the limit of the through hole 204, so that the fixed top frame 3 can be pulled out. Then, slide along the mounting slide 4 to pull out the photovoltaic tile body 1, completing the non-destructive disassembly.

[0024] Example 2: Please refer to Figures 1-5 Based on Embodiment 1, an overlapping structure is also disclosed, the specific structure of which is as follows: the outer wall of the side frame 2 and the outer wall of the fixed top frame 3 are provided with an overlapping structure for overlapping the photovoltaic tile body 1. The overlapping structure includes a skeleton slot 5 opened at the bottom of the fixed top frame 3, and the inner wall of the skeleton slot 5 is provided with a buffer pad 501. The outer walls on both sides of the side frame 2 are respectively provided with overlapping blocks 201 and overlapping grooves 202. The outer surface of the fixed top frame 3 is provided with a flange 6. The skeleton slot 5 is a through groove penetrating the bottom of the fixed top frame 3, and the skeleton slot 5 is connected to the roof frame. The frame is compatible, the buffer pad 501 is made of rubber, and the outer wall of the buffer pad 501 has anti-slip texture. The outer wall of the buffer pad 501 fits into the outer wall of the frame. The overlapping block 201 is set along the length of the side frame 2, and the outer surface of the overlapping block 201 is flush with the outer surface of the side frame 2. The cross-section of the overlapping block 201 is L-shaped. The overlapping groove 202 is compatible with the overlapping block 201. The outer surface of the fixed top frame 3 and the bottom end of the side frame 2 are both provided with flanges 6, and the bottom flange 6 of the side frame 2 overlaps with the top flange 6 of the adjacent fixed top frame 3.

[0025] When multiple photovoltaic tile bodies 1 are spliced, the frame slot 5 at the bottom of the fixed top frame 3 fits onto the roof frame. The rubber buffer pad 501 fills the gap between the slot and the frame through its own elastic deformation. Its surface anti-slip texture increases the friction coefficient and prevents the frame from sliding along the frame. When adjacent photovoltaic tiles are spliced, the L-shaped overlapping block 201 of one set of photovoltaic tile side frames 2 is embedded into the overlapping groove 202 of the adjacent photovoltaic tile side frames 2, forming a horizontal fitting limit. At the same time, the flange 6 at the bottom of the lower photovoltaic tile side frame 2 and the flange 6 at the top of the upper photovoltaic tile fixed top frame 3 overlap each other, forming a vertical overlapping constraint. Through the synergistic effect of horizontal fitting and vertical overlapping, multiple photovoltaic tiles form a continuous integral structure, which not only eliminates splicing gaps to ensure the integrity of the roof coverage, but also improves the overall wind load resistance and deformation resistance, adapting to the installation requirements of roofs with different slopes.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
