Description

Technical Field

[0001] The utility model relates to the technical field of flexible solar cell modules, in particular to an anti-cracking flexible solar cell module. Background Art

[0002] Solar cell modules, also known as solar panels, are the core part of solar power generation systems. They provide electricity by converting solar energy into electrical energy. There are many types of solar cell modules, among which flexible solar cell modules are one of them.

[0003] Flexible solar cell modules are a new type of solar panel that is flexible and bendable, making them suitable for installation on various shapes and surfaces.

[0004] Currently, the existing flexible solar cell modules may crack if the module body is bent for a long time, which greatly reduces the service life of the flexible solar cell modules.

[0005] Moreover, existing flexible solar cell modules are generally used outdoors. If they encounter acid rain, acidic raindrops will adhere to the surface of the module body. The long-term accumulation of acidic rainwater can easily cause the surface to be corroded by acidic moisture.

[0006] In addition, the side surfaces of existing flexible solar cell modules have weak anti-collision and friction properties and are easily scratched.

[0007] The above problems are widespread and urgently need improvement. Utility Model Content

[0008] The purpose of the utility model is to solve the above-mentioned shortcomings in the prior art and to propose an anti-cracking flexible solar cell assembly.

[0009] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0010] A crack-proof flexible solar cell assembly is designed, comprising a battery assembly body, wherein the side walls of the battery assembly body are provided with anti-cracking side frames, an outer wall adhesive layer is provided between the battery assembly body and the anti-cracking side frame, an embedded slot is provided on the anti-cracking side frame, an embedded adhesive layer is provided in the embedded slot, an embedded plug is provided on the outer wall adhesive layer, and an outer anti-cracking interlayer and an inner anti-cracking interlayer are respectively provided on the upper and lower end surfaces of the battery assembly body, an outer acid-resistant hydrophobic layer is provided at one end of the outer anti-cracking interlayer away from the battery assembly body, and an inner acid-resistant hydrophobic layer is provided at one end of the inner anti-cracking interlayer away from the battery assembly body.

[0011] Furthermore, the anti-cracking side frame is evenly laid along the side wall of the battery assembly body, the side cross-section of the anti-cracking side frame is a trapezoidal structure, and the anti-cracking side frame is made of highly elastic vulcanized rubber.

[0012] Furthermore, the outer anti-cracking interlayer and the inner anti-cracking interlayer are both made of PVB polyvinyl butyral highly light-transmitting flexible material, and the thickness of the outer anti-cracking interlayer and the inner anti-cracking interlayer is fifty to sixty microns.

[0013] Furthermore, the outer acid-resistant hydrophobic layer and the inner acid-resistant hydrophobic layer are both titanium dioxide nano-coatings, and the coating thickness of the outer acid-resistant hydrophobic layer and the inner acid-resistant hydrophobic layer is 100 to 150 nanometers.

[0014] Furthermore, the outer wall adhesive layer is evenly coated along the outer wall surface of the battery assembly body, and the outer wall adhesive layer and the embedded adhesive layer are both epoxy resin coating layers.

[0015] Furthermore, the embedded adhesive layer is evenly coated along the embedded slot, and the embedded plug is bonded to the embedded slot via the embedded adhesive layer.

[0016] Furthermore, the embedded plug-in blocks are evenly laid and bonded along the side walls of the battery assembly body and plugged into the embedded slots. The embedded plug-in blocks are made of PSU polysulfone material.

[0017] The utility model proposes an anti-cracking flexible solar cell module, which has the following beneficial effects:

[0018] 1. The utility model improves the overall anti-cracking performance of the battery assembly body by arranging an anti-cracking side frame structure on the outer side wall of the battery assembly body, and arranging an outer anti-cracking interlayer and an inner anti-cracking interlayer structure on the battery assembly body, effectively avoiding the battery assembly body from cracking due to long-term bending, thereby increasing the service life of the flexible solar cell assembly.

[0019] 2. The utility model provides an outer acid-resistant hydrophobic layer and an inner acid-resistant hydrophobic layer structure on the battery assembly body. When used outdoors in acid rain weather, the acid rain dripping on the surface of the battery assembly body can be quickly hydrophobicized and slid off, thereby preventing the acid raindrops from adhering to the surface of the battery assembly body for a long time and causing the surface to be corroded by acidic moisture.

[0020] 3. The utility model provides an anti-cracking side frame structure on the battery assembly body, thereby improving the anti-collision and friction properties of the side end surface and avoiding easy wear and tear.

[0021] 4. The present invention further improves the stability of the anti-cracking side frame bonded to the side wall of the battery assembly body by providing an outer wall adhesive layer with an embedded plug-in block on the battery assembly body and providing an embedded slot with an embedded adhesive layer on the anti-cracking side frame.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-5 A crack-proof flexible solar cell module comprises a battery module body 1, the side wall of the battery module body 1 is provided with an anti-cracking side frame 6, an outer wall adhesive layer 8 is provided between the battery module body 1 and the anti-cracking side frame 6, an embedded slot 61 is provided on the anti-cracking side frame 6, an embedded adhesive layer 62 is provided in the embedded slot 61, and an embedded plug 7 is provided on the outer wall adhesive layer 8. The upper and lower end surfaces of the battery module body 1 are respectively provided with an outer anti-cracking interlayer 2 and an inner anti-cracking interlayer 4, the outer anti-cracking interlayer 2 is provided with an outer acid-resistant hydrophobic layer 3 at one end away from the battery module body 1, and the inner anti-cracking interlayer 4 is provided with an inner acid-resistant hydrophobic layer 5 at one end away from the battery module body 1. The battery module body 1 is a flexible solar cell module, which is a prior art. Some existing structures are not drawn and marked, and there is no need to repeat them.

[0030] In detail, the anti-cracking side frame 6 is evenly laid along the side wall of the battery assembly body 1, and the side cross-section of the anti-cracking side frame 6 is a trapezoidal structure, which has strong stability.

[0031] The anti-cracking side frame 6 is made of highly elastic vulcanized rubber, and the body is collision-resistant, impact-resistant, corrosion-resistant and durable.

[0032] Furthermore, the outer anti-cracking interlayer 2 and the inner anti-cracking interlayer 4 are both made of PVB polyvinyl butyral highly light-transmitting and flexible materials. The thickness of the outer anti-cracking interlayer 2 and the inner anti-cracking interlayer 4 is fifty to sixty microns. The PVB polyvinyl butyral highly light-transmitting and flexible material has excellent anti-cracking performance. It is highly light-transmitting and flexible and elastic, and does not affect the flexibility of the battery component body 1 itself and the effect of absorbing sunlight.

[0033] Furthermore, the outer acid-resistant hydrophobic layer 3 and the inner acid-resistant hydrophobic layer 5 are both titanium dioxide nano-coatings. The coating thickness of the outer acid-resistant hydrophobic layer 3 and the inner acid-resistant hydrophobic layer 5 is one hundred to one hundred and fifty nanometers. The titanium dioxide nano-coating has excellent acid resistance and hydrophobicity, is a nano-scale coating, and has excellent flexibility and elasticity. It does not affect the flexibility of the battery component body 1 itself and the effect of absorbing sunlight.

[0034] In more detail, the outer wall adhesive layer 8 is evenly coated along the outer wall surface of the battery assembly body 1. The outer wall adhesive layer 8 and the embedded adhesive layer 62 are both epoxy resin coating layers. The epoxy resin coating layer is an adhesive based on epoxy resin, which has excellent bonding strength, chemical corrosion resistance, electrical insulation performance, as well as good heat resistance and aging resistance, which ensures the overall bonding stability of the anti-cracking side frame 6.

[0035] In general, the embedded adhesive layer 62 is evenly coated along the embedded slot 61, and the embedded plug-in block 7 is bonded to the embedded slot 61 through the embedded adhesive layer 62. The embedded plug-in bonding structure increases the effective bonding area, thereby improving the overall stability of the anti-cracking side frame 6 bonded to the side wall of the battery assembly body 1.

[0036] Finally, the embedded plug-in block 7 is evenly laid and glued along the side wall of the battery assembly body 1 and plugged into the embedded slot 61. The embedded plug-in block 7 is made of PSU polysulfone material. PSU polysulfone material has excellent high temperature resistance, chemical resistance and electrical insulation performance, and has excellent flexibility and elasticity, and does not affect the flexibility of the battery assembly body 1 itself.

[0037] Working method: By setting an anti-cracking side frame 6 structure on the outer side wall of the battery component body 1, and setting an outer anti-cracking interlayer 2 and an inner anti-cracking interlayer 4 structure on the battery component body 1, the overall anti-cracking performance of the battery component body 1 is improved, effectively avoiding the battery component body 1 from cracking due to long-term bending, thereby increasing the service life of the flexible solar cell module.

[0038] Moreover, by providing an outer acid-resistant hydrophobic layer 3 and an inner acid-resistant hydrophobic layer 5 structure on the battery assembly body 1, when used outdoors and encountering acid rain weather, the acid rain dripping on the surface of the battery assembly body 1 can be quickly hydrophobicized and slid off, thereby preventing the acidic raindrops from adhering to the surface of the battery assembly body 1 for a long time and causing the surface to be corroded by acidic moisture.

[0039] Furthermore, by providing an anti-cracking side frame 6 structure on the battery assembly body 1, the anti-collision and friction properties of the side end faces are improved, thereby avoiding the situation where they are easily scratched.

[0040] In addition, by providing an outer wall adhesive layer 8 with an embedded plug-in block 7 on the battery assembly body 1 and providing an embedded slot 61 with an embedded adhesive layer 62 on the anti-cracking side frame 6, the stability of the anti-cracking side frame 6 bonded to the side wall of the battery assembly body 1 is further improved.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
