Description

Technical Field

[0001] This utility model relates to the field of solar cell module technology, specifically a frameless solar cell module. Background Technology

[0002] With the development of photovoltaic technology, solar cell modules are widely used in industrial, commercial, and residential buildings. To improve the structural stability and durability of the modules during transportation, installation, and operation, traditional solar cell modules generally adopt an encapsulation structure with a metal frame. This structure can provide a certain degree of protection for the edges of the photovoltaic panel and provide some structural support for the assembly of modules.

[0003] A typical traditional solar cell module structure usually includes: a photovoltaic panel encapsulated with EVA and glass layers, surrounded by an aluminum alloy frame to reinforce the structure, prevent edge damage, and provide mechanical connection with adjacent modules. Furthermore, for electrical connection, modules need to be connected in series or parallel via external wires, cables, or plugs / sockets. During installation, the modules are secured to the support frame using screws, connectors, etc., simultaneously achieving electrical connection and mechanical stability.

[0004] Despite the widespread use of the above structure, the following main problems and shortcomings still exist: The frame structure creates thickness and gaps around the modules, limiting the assembly density of photovoltaic modules, affecting system space utilization, and hindering applications in densely packed scenarios (such as BIPV and sunrooms). Traditional framed modules typically require mechanical assembly using bolts, connecting blocks, and other additional components, resulting in complex installation, low on-site construction efficiency, and the need to disassemble multiple fasteners for maintenance or replacement, impacting the construction cycle. In frameless module design attempts, the lack of structural protection measures makes the module edges susceptible to damage during transportation and installation, reducing reliability and limiting the widespread application of frameless solutions.

[0005] Therefore, there is an urgent need for a frameless solar cell module structure that is structurally sound, easy to assemble, has protective edges, and highly integrated mechanical and electrical connections, in order to overcome the problems existing in the above-mentioned technologies and improve the module's integration, installation efficiency, and safety of use. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0007] To address the shortcomings of existing photovoltaic modules in terms of edge protection, electrical connection, and rapid assembly, this invention proposes a frameless solar cell module that achieves a combination of functions including compact structure, edge protection, rapid assembly, and electrical interconnection.

[0008] This invention provides a frameless solar cell module, including a photovoltaic panel, a base, and connectors. Through a modular structural design, combined with protective plates and elastic components, automatic edge protection is achieved. Furthermore, the mushroom-shaped contact structure and male / female pole structure enable integrated mechanical and electrical connections between modules, resulting in excellent installation convenience, structural reliability, and system adaptability.

[0009] In a preferred embodiment, the photovoltaic panel is fixedly adhered to the upper surface of the base. Multiple protective plates are slidably mounted on the surface of the base, located on the bottom surface of the photovoltaic panel, to provide physical protection for the edges of the photovoltaic panel when the module is not assembled. Specifically, the protective plates can elastically extend under the action of elastic elements to achieve active edge protection of the module. When the module is assembled, they can automatically retract into the base surface without affecting the bonding connection between the modules. This structure allows the module to maintain a frameless design while providing effective edge protection, improving impact resistance and safety.

[0010] In a preferred embodiment, the base is fixedly provided with engaging wings around its perimeter, and engaging members are provided on the outer surface of the engaging wings. Each engaging member includes a mounting plate and a plurality of mushroom-shaped protrusions distributed on its surface. The mushroom-shaped protrusions have a cylindrical mushroom-shaped structure, arranged in a matrix along the surface of the mounting plate, and are used for mating connections with the mushroom-shaped protrusions of adjacent components. Specifically, this mushroom-shaped protrusion structure provides a reliable mechanical locking effect, enabling rapid assembly between components while possessing good vibration resistance and repeated insertion / removal capability, thus improving installation efficiency and maintenance convenience.

[0011] In a preferred embodiment, the joining wing is provided with a male pole and a female pole, respectively mounted on both sides of the component. The male pole is a protruding structure, and the female pole is a matching groove structure; both are made of conductive metallic material. When the two components are spliced ​​together, the male pole and female pole naturally align, completing the electrical interconnection between the components. Specifically, this structure eliminates the cumbersome process of traditional cable connections, significantly improving the electrical connection efficiency of the components while ensuring electrical reliability and reducing the risk of wiring errors.

[0012] In a preferred embodiment, an inverter control box is fixedly mounted on the bottom surface of the base for receiving electrical energy from the photovoltaic panels and performing DC-to-AC inversion. The output terminals of the photovoltaic panels are connected to the input terminals of the inverter control box via wires. The output electrodes of the inverter control box are connected to the male and female terminals respectively, realizing distributed power output from the modules within the system. Specifically, this configuration simplifies the wiring design between modules and improves the overall electrical system integration, making it suitable for building-integrated photovoltaics (BIPV) or large-scale photovoltaic array applications.

[0013] In a preferred example, the joining wing and the joining member are vertically disposed on the bottom surface of the base, and their outer surfaces are in the same vertical plane as the side surface of the base. Specifically, this structural design allows multiple components to be aligned and fitted horizontally during assembly, achieving seamless connection and improving the overall consistency and sealing effect of the photovoltaic system. It is particularly suitable for building-integrated projects with high requirements for aesthetics and density.

[0014] In a preferred example, the gap between the mushroom-shaped protrusions is less than or equal to the diameter of their top mushroom heads, ensuring a certain interference fit during mating. Specifically, this mating structure provides insertion and positioning functionality while possessing good pull-out resistance, making it suitable for the long-term stable operation of outdoor photovoltaic systems.

[0015] In summary, the frameless solar cell module provided by this utility model, through the setting of sliding guard plates and elastic elements, mushroom-shaped convex contact connection structure, male and female pole electrical connection structure, and modular assembly design, has achieved significant improvements in structural strength, edge protection, rapid splicing, electrical interconnection, and system integration, and has good prospects for promotion and application.

[0016] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, by setting a cooperative structure between the sliding guard plate and the elastic element, the guard plate automatically pops out in the non-spliced ​​state, effectively protecting the edge of the photovoltaic panel. In the spliced ​​state, it can be retracted and hidden, realizing that the photovoltaic module still has edge protection function in the frameless state, improving the safety and structural integrity of the module.

[0017] 2. In this utility model, the base is provided with connecting wings and integrated connecting parts around its perimeter. It adopts an interlocking structure of mounting plates and mushroom-shaped protrusions, which enables rapid assembly and stable connection between adjacent photovoltaic panels. At the same time, it enables automatic electrode docking, which greatly improves the installation efficiency of the components, the reliability of electrical connections, and the convenience of modular application.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0021] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0022] The following describes, with reference to the accompanying drawings, some embodiments of a frameless solar cell module provided by this utility model.

[0023] Combination Figures 1-6 As shown, the present invention provides a frameless solar cell module, including a photovoltaic panel 100, a base 200 and a connector 300.

[0024] The photovoltaic panel 100 is fixedly attached to the upper surface of the base 200 to receive sunlight and output electrical energy. The base 200 serves as a structural support, and multiple protective plates 210 are slidably mounted on its upper surface. These protective plates 210 are located on the bottom surface of the photovoltaic panel 100 and are used to protect its edges. Preferably, there are four protective plates 210, evenly distributed along the four edges of the photovoltaic panel 100.

[0025] like Figure 2 , Figure 4 As shown, the protective plates 210 are divided into two groups, with multiple staggered toothed rods between each group of protective plates 210. The toothed rod structure enables relative sliding guidance between the two protective plates 210. Each group of protective plates 210 has an elastic element 211 installed at the end of the toothed rod, which is used to elastically push the protective plate 210 out when the modules are not spliced, allowing the outer end of the protective plate 210 to extend beyond the photovoltaic panel 100, thus providing physical protection for the edge. When the modules are spliced ​​together, due to external pressure, the protective plates 210 are pressed back onto the surface of the base 200, thus not affecting the splicing between adjacent modules.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 6As shown, the base 200 is fixedly mounted with connecting wings 220 around its perimeter, and each connecting wing 220 has a connecting member 300 on its outer surface. The connecting member 300 includes a mounting plate 310 and a plurality of mushroom-shaped protrusions 320 disposed on its surface. The mushroom protrusions 320 preferably adopt a cylindrical mushroom nail structure, and the plurality of mushroom protrusions 320 are arranged in a matrix on the surface of the mounting plate 310. The mushroom protrusions 320 between two adjacent components are interlocked to achieve a stable mechanical interlock, thereby ensuring the firmness of the components after assembly.

[0027] like Figure 2 , Figure 3 , Figure 6 As shown, the joining wing 220 is provided with a male pole 221 and a female pole 222 respectively arranged on both sides of the component. Preferably, the male pole 221 is an anode protrusion structure and the female pole 222 is a cathode groove structure. The two are matched in shape and can achieve electrical connection. Both the male pole 221 and the female pole 222 are made of metal components, which have good electrical conductivity and mechanical strength.

[0028] During assembly, adjacent components are mechanically connected via connectors 300 and electrically connected via automatic docking of male pole 221 and female pole 222. This connection method not only improves assembly efficiency but also enhances the conductivity reliability between components, making it suitable for the construction of large-scale photovoltaic module arrays.

[0029] like Figure 3 As shown, an inverter control box 230 is fixedly installed on the bottom surface of the base 200. The inverter control box 230 is used to convert the DC power output by the photovoltaic panel 100 into AC power or to perform energy management. The output terminal of the photovoltaic panel 100 is connected to the input terminal of the inverter control box 230 via a cable. The output terminal of the inverter control box 230 is connected to the public terminal 221 and the public terminal 222 respectively, thereby realizing the power interconnection between the entire group of modules.

[0030] Preferably, the joining wing 220 and the joining member 300 are both vertically arranged on the bottom surface of the base 200, and the outer surfaces of the joining wing 220 and the joining member 300 are in the same vertical plane as the side surface of the base 200. This structural design allows multiple photovoltaic panels 100 to fit tightly together during the splicing process, achieving a seamless connection and further improving the space utilization and overall aesthetics of the photovoltaic system.

[0031] like Figure 5 As shown, the number of mushroom protrusions 320 is several and evenly distributed on the surface of the plate 310. The gap between the mushroom protrusions 320 is less than or equal to the diameter of the mushroom head at the top of the mushroom protrusion 320, thereby ensuring good mating stability and a certain vibration resistance during the mating process. The interlocking structure of the flexible mushroom protrusions 320 being inserted into each other ensures the stability and durability after the mating.

[0032] In summary, this utility model achieves edge elastic protection for the frameless photovoltaic panel 100 by setting a protective plate 210 and an elastic element 211 around the photovoltaic module; and achieves the integration of mechanical structure assembly and electrical connection by setting a connecting wing 220, a connecting element 300, a mushroom-shaped protrusion 320, and male pole 221 and female pole 222, effectively improving the modular assembly efficiency and operational safety of the module.

[0033] Working principle and usage process of this utility model: The photovoltaic panel 100 receives sunlight and converts solar energy into electrical energy. The output of the photovoltaic panel 100 is electrically connected to the input of the inverter control box 230 via a connecting cable. The inverter control box 230 processes the direct current, and its output is then electrically connected to adjacent modules via a male pole 221 and a female pole 222, enabling series or parallel connection between modules. Each module's base 200 is equipped with a connecting wing 220 and a connecting member 300, forming a detachable mechanical lock between modules via mushroom-shaped protrusions 320 on the mounting plate 310. The mushroom-shaped protrusions 320 arranged in a matrix of connectors 300 have interlocking and limiting functions, ensuring stable assembly and convenient disassembly. The protective plate 210 can slide along the base surface. In the non-assembled state, it pops out under the action of the elastic element 211 to cover the edge of the photovoltaic panel, forming edge protection. In the assembled state, the protective plate 210 is pressed back when adjacent components are pressed together, so as not to interfere with the splicing, ensuring the frameless effect of the module while providing protection.
