Technical Field
[0001] This utility model belongs to the field of photovoltaic module packaging technology, specifically relating to a corner protector component for packaging photovoltaic modules. Background Technology
[0002] During the production, transportation, and storage of photovoltaic (PV) modules, corner protectors are typically used to protect the edges and corners from collisions, abrasions, and other damage. Traditional corner protectors are relatively simple in structure and have a single function, presenting numerous inconveniences in packaging and securing PV modules. For example, the connections between corner protectors are not secure enough, making them prone to loosening or detachment during transportation, thus failing to effectively protect the PV modules. Furthermore, the materials and structural designs of traditional corner protectors are not well-suited to PV modules of different specifications and shapes, resulting in poor versatility. Therefore, developing a new type of corner protector assembly for packaging PV modules is of significant practical importance. Utility Model Content
[0003] The purpose of this invention is to provide a corner protector for packaging photovoltaic modules, thereby addressing the problems mentioned in the background art.
[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:
[0005] A corner protector assembly for packaging photovoltaic modules includes four sets of corner protectors, characterized in that: the cross-section of the corner protector is an isosceles triangle, the inner side of the corner protector is provided with a right-angle groove for connecting with the photovoltaic panel, and the end of the corner protector is provided with a circular groove, in which two sets of connecting structures are provided vertically distributed;
[0006] The connecting structure includes a take-up reel rotatably mounted in the circular groove via a rotating shaft, the take-up reel being wound with a connecting belt, a circular shell being fixedly installed in the circular groove, a coil spring being disposed inside the circular shell, and the rotating shaft extending into the circular shell and connecting to the coil spring.
[0007] The connecting strips of two adjacent corner protectors are connected to each other.
[0008] The corner protector has rounded corners at the top.
[0009] The corner protectors are made of fiberglass material.
[0010] The two side walls of the right-angle groove are each provided with several linearly distributed locking strips.
[0011] One of the connecting strips has a connecting ring fixed to its end, and the other connecting strip has a buckle fixed to its end.
[0012] This invention, through the design of connecting straps, connecting rings, and buckles, enables adjacent corner protectors to be quickly and securely connected, forming a complete corner protector assembly. This effectively prevents the corner protectors from loosening or falling off during transportation, thus improving the protection of photovoltaic modules.
[0013] The design of the coil spring and winding reel in this invention gives the connecting belt a certain degree of elasticity, which can automatically adjust the length of the connecting belt according to the size and shape of the photovoltaic module, adapting to photovoltaic modules of different specifications and shapes, and has good versatility and adaptability.
[0014] The rounded corner design at the top of this corner protector reduces safety hazards, and the use of fiberglass material ensures the strength and durability of the corner protector, providing long-term and reliable protection for photovoltaic modules.
[0015] The design of the right-angle groove and locking strip in this utility model facilitates the quick positioning and connection of the corner protector and the photovoltaic panel. The setting of the connecting ring and the locking buckle makes the connection operation between the corner protectors simple and convenient, and improves the packaging efficiency.

[0023] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0024] like Figures 1-4As shown, this utility model discloses a corner protector assembly for packaging photovoltaic modules, comprising four sets of corner protectors 1. Each corner protector 1 has an isosceles triangular cross-section, a design that better conforms to the edges and corners of the photovoltaic module, providing uniform support and protection. The inner side of each corner protector 1 has a right-angle groove 11 for connection with the photovoltaic panel. The edges and corners of the photovoltaic panel can be embedded into the right-angle groove 11, achieving initial positioning and connection between the corner protector and the photovoltaic panel. Several linearly distributed retaining strips 111 are provided on both sides of the right-angle groove 11. These strips 111 increase the friction between the right-angle groove 11 and the photovoltaic panel, preventing the corner protector 1 from sliding on the photovoltaic panel and improving connection stability.
[0025] The corner protector 1 has a circular groove 12 at one end, and two sets of connecting structures are arranged vertically within the circular groove 12. Each connecting structure includes a winding reel 2 rotatably mounted within the circular groove 12 via a rotating shaft, with a connecting strip 21 wound around it. A circular shell 22 is fixedly installed within the circular groove 12, and a coil spring 23 is disposed within the circular shell 22. The rotating shaft extends into the circular shell 22 and connects to the coil spring 23. The coil spring 23 is elastic; in its natural state, the coil spring 23 causes the winding reel 2 to automatically wind up the connecting strip 21, maintaining a certain tension on the connecting strip 21.
[0026] The connecting straps 21 of two adjacent corner protectors 1 are interconnected. One end of the connecting strap 21 is fixed with a connecting ring 211, and the other end of the connecting strap 21 is fixed with a buckle 212. By fastening the buckle 212 into the connecting ring 211, the two adjacent corner protectors 1 can be quickly connected and fixed. The four sets of corner protectors 1 are interconnected through the connecting straps 21 to form a complete corner protection assembly, which can protect the four corners of the photovoltaic module in all directions.
[0027] The corner protector 1 has rounded corners at the top. The rounded corner design can prevent the top of the corner protector 1 from being too sharp, reduce the risk of injury to operators during handling and installation, and also prevent scratching other objects.
[0028] The corner protector 1 is made of fiberglass material, which has the advantages of high strength, light weight, corrosion resistance and good insulation. It can meet the performance requirements of photovoltaic module packaging for corner protector materials, while reducing the overall weight of the corner protector assembly, making it easier to handle and install.
[0029] A corner protector 1 with an isosceles triangular cross-section is manufactured using fiberglass material and a molding process. A right-angle groove 11 is machined into the inner side of the corner protector 1, and several linearly distributed retaining strips 111 are formed on the two side walls of the right-angle groove 11 using machining or injection molding. A circular groove 12 is formed at the end of the corner protector 1, and a connecting structure is installed within the circular groove 12.
[0030] Install the rotating shaft in the circular groove 12, and then rotate the take-up reel 2 in the circular groove 12 via the rotating shaft. Wrap the connecting strap 21 around the take-up reel 2, ensuring that the connecting strap 21 can be freely wound and unwound. Fix the circular shell 22 in the circular groove 12, place the coil spring 23 inside the circular shell 22, and extend the rotating shaft into the circular shell 22 to connect with the coil spring 23, so that the coil spring 23 can provide elastic force to the take-up reel 2.
[0031] A connecting ring 211 is fixed to one end of one connecting band 21, and a latch 212 is fixed to the other end of the connecting band 21, ensuring that the latch 212 can be securely fastened into the connecting ring 211. The latch 212 is a conventional latch 212 in the prior art, such as a key ring design.
[0032] Four sets of pre-made corner protectors 1 are placed at the four corners of the photovoltaic module, so that the corners of the photovoltaic panel are embedded in the right-angle grooves 11, and the retaining strips 111 are in close contact with the photovoltaic panel. Then, the connecting straps 21 of two adjacent corner protectors 1 are pulled out, so that the locking buckles 212 are engaged in the connecting rings 211. The length of the connecting straps 21 is adjusted to secure the corner protector assembly to the photovoltaic module. Due to the action of the coil spring 23, the connecting straps 21 will maintain a certain tension, ensuring that the connection of the corner protector assembly is stable and reliable.
[0033] During use, the corner protector provides all-around protection for the photovoltaic module, preventing the corners from being bumped and worn. When it is necessary to remove the corner protector, simply press the latch 212 to release it from the connecting ring 211, and then the coil spring 23 will automatically rewind the connecting strip 21 back onto the reel 2. Finally, the corner protector 1 can be removed from the photovoltaic module.
[0034] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
