[0031] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0032] The corner protection device 100 for a photovoltaic module 200 according to an embodiment of the present invention is described below with reference to the accompanying drawings. It includes: a first corner protection body 10, the first corner protection body 10 including a first sub-corner protection body 11 and a second sub-corner protection body 12, the first sub-corner protection body 11 and the second sub-corner protection body 12 being bent and connected, both the first sub-corner protection body 11 and the second sub-corner protection body 12 being constructed as an elastic body, at least one of the first sub-corner protection body 11 and the second sub-corner protection body 12 being adapted to be bonded to the frame 201 of the photovoltaic module 200 so that the corner protection device 100 covers the corners 202 of the frame 201.

[0033] Among them, such as Figure 1 , Figure 3 , Figure 5 As shown, both the first sub-corner protector body 11 and the second sub-corner protector body 12 can be constructed as rectangular plates. The first sub-corner protector body 11 and the second sub-corner protector body 12 are bent and connected. As some embodiments of this utility model, the first sub-corner protector body 11 and the second sub-corner protector body 12 can be bonded together, or the first sub-corner protector body 11 and the second sub-corner protector body 12 can be integrally formed. However, this utility model is not limited to this. The first sub-corner protector body 11 and the second sub-corner protector body 12 can also be connected in other ways, as long as the first sub-corner protector body 11 and the second sub-corner protector body 12 are bent and connected. The bending angle of the first sub-corner protector body 11 and the second sub-corner protector body 12 can be adjusted according to the angle of the corner 202 of the frame 201 of the photovoltaic module 200 to adapt to the angle of the corner 202 of the frame 201 of the photovoltaic module 200, so that the corner protector device 100 can better fit the contour of the corner 202 of the frame 201 of the photovoltaic module 200, and improve the adaptability of the corner protector device 100. The corners 202 of the frame 201 are formed by connecting two adjacent frame strips of the frame 201 with beveled or straight cuts. The corners 202 are relatively sharp, which can easily scratch installers and cause stress concentration. The bent structure of the first sub-corner protector body 11 and the second sub-corner protector body 12 can effectively disperse external impact force and avoid stress concentration, thereby improving the impact resistance and durability of the corner protector device 100. The bent connection between the first sub-corner protector body 11 and the second sub-corner protector body 12 can also be designed as a smooth transition structure to avoid the sharp corners 202 from scratching or damaging installers or objects, while also improving the overall aesthetics.

[0034] Both the first sub-corner protector body 11 and the second sub-corner protector body 12 are constructed as elastomers. The elastomers can be materials such as thermoplastic olefin elastomers (TPO), thermoplastic dynamic vulcanizates (TPV), thermoplastic polyurethanes (TPU), ethylene-vinyl acetate copolymer elastomers (EVA), silicone rubber, and ethylene propylene diene monomer (EPDM). The density of the elastomer can be as low as 0.7 g / cm³. 3 -1.2g / cm 3Within a certain range, the density of the elastomer can be as low as 0.7 g / cm³. 3 0.8g / cm 3 0.9g / cm 3 1.2g / cm 3 The density of the elastomer can be 0.7 g / cm³, but this invention is not limited to this value. 3 -1.2g / cm 3 Other values ​​between these ranges set the density range of the elastomer at 0.7 g / cm³. 3 1.2g / cm 3 Within the range, it can maintain sufficient mechanical strength to meet protection requirements while significantly reducing the weight of the corner protector 100. It avoids structural fragility due to excessive weight reduction, absorbs energy through deformation, and does not have insufficient rebound due to excessive softness, ensuring that it can maintain cushioning performance after long-term use.

[0035] The elastomer possesses excellent elastic deformation capabilities. When the frame 201 is impacted, the elastomer corner protector 100 can effectively absorb external impact force, quickly return to its original shape, maintain its protective performance, reduce damage to the photovoltaic module 200 from collisions or vibrations, and extend the service life of the photovoltaic module 200. The elastomer corner protector 100 can slightly deform according to the shape or surface unevenness of the frame 201 of the photovoltaic module 200, thereby better conforming to the surface of the frame 201 of the photovoltaic module 200 and improving the protective effect. The elastomer corner protector 100 is soft in texture, easy to bend and install, requiring no complicated tools or fixing methods, reducing installation difficulty and cost. The elastomer material has a high surface friction coefficient, which can reduce the risk of the corner protector 100 slipping or falling off when subjected to external force, ensuring the reliability of protection. Compared with rigid corner protectors 100, the elastomer corner protector 100 will not produce sharp fragments or flying debris upon collision, reducing the risk of secondary injury to personnel or objects. Compared with paper corner protectors 100, elastomer corner protectors 100 can effectively absorb impact force, provide stronger cushioning and shock absorption, have good anti-aging and wear resistance, and can maintain high-strength protective effect for a long time.

[0036] At least one of the first sub-corner protector body 11 and the second sub-corner protector body 12 is adapted to be bonded to the frame 201 of the photovoltaic module 200. In some embodiments of the present invention, the first sub-corner protector body 11 is adapted to be bonded to the frame 201 of the photovoltaic module 200, or the second sub-corner protector body 12 is adapted to be bonded to the frame 201 of the photovoltaic module 200, or both the first sub-corner protector body 11 and the second sub-corner protector body 12 are adapted to be bonded to the frame 201 of the photovoltaic module 200. The present invention uses the first sub-corner protector body 11 and the second sub-corner protector body 12 as the primary components of the photovoltaic module 200. Taking the example of both being suitable for bonding to the frame 201 of the photovoltaic module 200, the first sub-corner protector body 11 and the second sub-corner protector body 12 are both suitable for bonding to the frame 201 of the photovoltaic module 200, so that the corner protector device 100 covers the corners 202 of the frame 201. No additional fasteners or complex installation tools are required, which significantly shortens the installation time. The bonding method can achieve a seamless fit between the corner protector device 100 and the frame 201 of the photovoltaic module 200, avoid blind spots caused by gaps, and improve the overall protective effect of the corner protector device 100.

[0037] Therefore, by bonding the corner protector 100 made of elastomeric material of this utility model to the frame 201 of the photovoltaic module 200, the photovoltaic module 200 can be effectively protected, reducing the risk of abnormalities such as frame 201 deformation and bursting during transportation. It can also reduce the scratches on the corners 202 of the photovoltaic module 200 to the installers during the installation process.

[0038] According to the present invention, the corner protector 100 for a photovoltaic module 200 is constructed by making both the first sub-corner protector body 11 and the second sub-corner protector body 12 as elastic bodies, so that the corner protector 100 can have a buffering capacity, which can effectively protect the photovoltaic module 200 and reduce the risk of abnormalities such as deformation of the frame 201 or bursting of the photovoltaic module 200 during transportation. At least one of the first sub-corner protector body 11 and the second sub-corner protector body 12 is suitable for bonding to the frame 201 of the photovoltaic module 200 so that the corner protector 100 covers and fixes the corners 202 of the frame 201, which can reduce the scratches on the corners 202 of the photovoltaic module 200 to the installers during the installation process.

[0039] According to some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the first corner protector body 10 may further include a connector 13, which is also constructed as an elastic body. The connector 13 is connected between the first sub-corner protector body 11 and the second sub-corner protector body 12 so that the first sub-corner protector body 11 and the second sub-corner protector body 12 are bent and connected. The connector 13 is arc-shaped to define an installation space 14 for mounting the corner 202.

[0040] The connector 13, acting as an elastic body, can naturally bend and maintain a set angle, allowing the first sub-corner protector 11 and the second sub-corner protector 12 to flexibly adjust their relative positions to adapt to corners 202 of different angles (such as right angles, obtuse angles, etc.). The arc-shaped connector 13 not only has its own shock-absorbing effect but also enhances the overall shock-absorbing performance of the corner protector device 100 through its elastic deformation. When subjected to external force, the arc-shaped connector 13 can evenly distribute stress throughout the entire structure, avoiding damage or failure caused by localized stress concentration. This maintains the continuous and effective protection of the photovoltaic module 200's frame 201 by the corner protector device 100, thereby improving the overall protection level of the corner protector device 100. The installation space 14 defined by the arc-shaped connector 13 can adapt to corners 202 of different sizes and shapes, improving the versatility and applicability of the corner protector device 100.

[0041] According to some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the connector 13 can be constructed in an arc shape. The arc-shaped structure can evenly distribute external impact force or bending stress across the entire arc surface, avoiding local stress concentration (such as stress peaks that are easily generated by right-angle connections), thereby improving the overall structural strength of the corner protector 100. The arc transition reduces fatigue damage to the material under repeated stress. When subjected to force, the arc-shaped connector 13 can achieve elastic deformation through arc surface compression or stretching, absorbing more impact energy, enhancing the shock absorption effect, and thus effectively extending the service life of the connector 13.

[0042] According to some embodiments of the present invention, such as Figure 1 , Figure 3 and Figure 5 As shown, the first sub-corner protector body 11 and the second sub-corner protector body 12 can be perpendicular. The vertical structure can fit the 90° right angle corner 202 of the frame 201 of the photovoltaic module 200. The first sub-corner protector body 11 and the second sub-corner protector body 12 form a continuous protective surface at the right angle of the frame 201, which can resist the impact force from two vertical directions at the same time (such as transportation collisions and daily bumps), and avoid the failure of the unidirectional corner protector device 100 under multi-angle impacts.

[0043] According to some embodiments of the present invention, such as Figure 5 and Figure 6 As shown, the corner protector device 100 may further include: a second corner protector body 20, which is also constructed as an elastic body; a first sub-corner protector body 11 and a second sub-corner protector body 12 are located on the same side of the second corner protector body 20; and the second corner protector body 20 is fixedly connected to the first sub-corner protector body 11 and the second sub-corner protector body 12; and the first sub-corner protector body 11 and the second sub-corner protector body 12 are both extended along the outer edge of the second corner protector body 20.

[0044] The second corner protector body 20 is also constructed as an elastic body, allowing the second corner protector body 20 and the first corner protector body 10 to absorb impact energy through coordinated deformation, and improving the shock absorption effect through graded deformation. The second corner protector body 20 is fixedly connected to the first sub-corner protector body 11 and the second sub-corner protector body 12. In some embodiments of this utility model, the second corner protector body 20 can be fixedly connected to the first sub-corner protector body 11 and the second sub-corner protector body 12 by adhesive bonding, or the second corner protector body 20 can be integrally formed with the first sub-corner protector body 11 and the second sub-corner protector body 12. However, this utility model is not limited to this. The second corner protector body 20 can also be fixedly connected to the first sub-corner protector body 11 and the second sub-corner protector body 12 by other means, as long as the second corner protector body 20 is fixedly connected to the first sub-corner protector body 11 and the second sub-corner protector body 12.

[0045] The second corner protector body 20 is fixedly connected to the first sub-corner protector body 11 and the second sub-corner protector body 12 and can be integrally formed to create a continuous protective structure. This avoids installation gaps or misalignment problems that may occur with a split design, ensuring the integrity of the protection. The first sub-corner protector body 11 and the second sub-corner protector body 12 both extend along the outer edge of the second corner protector body 20, which helps to maximize the use of the space of the corner protector device 100, forming a multi-directional wrapping of the corners 202 of the frame 201 of the photovoltaic module 200, reducing blind spots, and further improving the protective effect of the corner protector device 100.

[0046] Furthermore, the second corner protector body 20 may include a straight section 24 and an arc-shaped section 25. The two end faces of the straight section 24 and the arc-shaped section 25 are fixedly connected to define a buffer space 23. The side of the straight section 24 away from the arc-shaped section 25 is the outer side of the second corner protector body 20. The first sub-corner protector body 11 and the second sub-corner protector body 12 are both extended along the edge of the straight section 24 of the second corner protector body 20 to construct a space for installing the corner 202, forming a multi-directional wrapping of the corner 202 of the frame 201 of the photovoltaic module 200, reducing blind spots, and further improving the protective effect of the corner protector device 100.

[0047] According to some embodiments of the present invention, such as Figure 5 As shown, the shape of the first corner protector body 10 is adapted to the shape of the second corner protector body 20; and / or

[0048] The second corner protector body 20 has a buffer space 23.

[0049] The shapes of the first corner protector body 10 and the second corner protector body 20 are adapted to each other, so that the shapes of the first corner protector body 10 and the second corner protector body 20 can be seamlessly spliced, avoiding blind spots or structural defects caused by shape mismatch. The adapted shapes enhance the overall rigidity of the corner protector device 100 through geometric constraints, reducing deformation or displacement caused by external forces. The adapted first corner protector body 10 and the second corner protector body 20 can provide synergistic protection against impact forces from different directions, avoiding weak points in protection caused by shape mismatch.

[0050] Alternatively, the second corner protector body 20 may have a buffer space 23. Specifically, the second corner protector body 20 may include a straight section 24 and an arc-shaped section 25. The two end faces of the straight section 24 and the arc-shaped section 25 are fixedly connected to define a buffer space 23. The side of the straight section 24 away from the arc-shaped section 25 is the outer side of the second corner protector body 20. The first sub-corner protector body 11 and the second sub-corner protector body 12 are both extended along the edge of the straight section 24 of the second corner protector body 20 to construct a space for the triangular force-bearing installation corner 202, forming a multi-directional wrapping of the corner 202 of the frame 201 of the photovoltaic module 200, reducing the blind spot of protection. When the photovoltaic module 200 is hit, the buffer space 23 can serve as a first-level buffer layer. When it is impacted by external force, it first deforms and absorbs some energy. Subsequently, the elastic material of the corner protector device 100 serves as a second-level buffer layer to further disperse the remaining energy, so that the corner protector device 100 can maintain efficient protection under different impact velocities, thereby further improving the protective effect of the corner protector device 100.

[0051] Alternatively, the shapes of the first corner protector body 10 and the second corner protector body 20 can be matched, and the second corner protector body 20 forms a buffer space 23 (this embodiment is used as an example for explanation). This configuration enhances the overall rigidity of the corner protector device 100 through geometric constraints, reducing deformation or displacement caused by external forces. The matched first corner protector body 10 and the second corner protector body 20 can provide synergistic protection against impacts from different directions, avoiding weak points in protection due to shape mismatch. Furthermore, the buffer space 23, acting as a first-level buffer layer, deforms first upon impact, absorbing some energy. Subsequently, the elastomeric material of the corner protector device 100, acting as a second-level buffer layer, further disperses the remaining energy, ensuring that the corner protector device 100 maintains efficient protection at different impact velocities, thereby further improving the protective effect of the corner protector device 100.

[0052] According to some embodiments of the present invention, such as Figure 5As shown, the second corner protector body 20 may include: a third sub-corner protector body 21 and a fourth sub-corner protector body 22. The third sub-corner protector body 21 and the fourth sub-corner protector body 22 are bent and connected. The third sub-corner protector body 21 is correspondingly connected to the first sub-corner protector body 11, and the fourth sub-corner protector body 22 is correspondingly connected to the second sub-corner protector body 12.

[0053] Both the third sub-corner protector body 21 and the fourth sub-corner protector body 22 can be constructed as rectangular plates. The third sub-corner protector body 21 and the fourth sub-corner protector body 22 are bent and connected. As some embodiments of this utility model, the third sub-corner protector body 21 and the fourth sub-corner protector body 22 can be bonded together, or they can be integrally formed. However, this utility model is not limited to this; the third sub-corner protector body 21 and the fourth sub-corner protector body 22 can also be connected in other ways, as long as they are bent and connected. The bent connection of the third sub-corner protector body 21 and the fourth sub-corner protector body 22 can be adjusted according to the angle of the corner 202 of the frame 201 of the photovoltaic module 200, so as to adapt to the angle of the corner 202 of the frame 201 of the photovoltaic module 200, allowing the corner protector device 100 to better fit the contour of the corner 202 of the frame 201 of the photovoltaic module 200, thus improving the adaptability of the corner protector device 100. The bending structure effectively disperses external impact forces and avoids stress concentration, thereby improving the impact resistance and durability of the corner protector 100. The bending structure can also be designed with a smooth transition to prevent sharp edges 202 from causing scratches or damage to installers or objects, while also enhancing the overall aesthetics.

[0054] The third sub-corner protector body 21 and the first sub-corner protector body 11 are connected accordingly. As some embodiments of this utility model, the third sub-corner protector body 21 and the first sub-corner protector body 11 can be bonded together, or the third sub-corner protector body 21 and the first sub-corner protector body 11 can be integrally formed. However, this utility model is not limited to this. The third sub-corner protector body 21 and the first sub-corner protector body 11 can also be connected in other ways, as long as the third sub-corner protector body 21 and the first sub-corner protector body 11 are connected accordingly.

[0055] The fourth sub-corner protector body 22 and the second sub-corner protector body 12 are connected accordingly. As some embodiments of this utility model, the fourth sub-corner protector body 22 and the second sub-corner protector body 12 can be bonded together, or the fourth sub-corner protector body 22 and the second sub-corner protector body 12 can be integrally formed. However, this utility model is not limited to this. The fourth sub-corner protector body 22 and the second sub-corner protector body 12 can also be connected in other ways, as long as the fourth sub-corner protector body 22 and the second sub-corner protector body 12 are connected accordingly.

[0056] The third sub-corner protector body 21 is connected to the first sub-corner protector body 11, and the fourth sub-corner protector body 22 is connected to the second sub-corner protector body 12. Together, they define an installation space 14 that fits the corner 202 of the frame 201 of the photovoltaic module 200 for installing the corner 202, forming a stable triangular force-bearing structure and significantly improving impact resistance. When the photovoltaic module 200 is subjected to external impact, the correspondingly connected third sub-corner protector body 21 and first sub-corner protector body 11, and the correspondingly connected fourth sub-corner protector body 22 and second sub-corner protector body 12, through coordinated deformation, disperse the stress to the entire corner protector device 100, avoiding cracking or detachment caused by local stress concentration, and further improving the safety of the photovoltaic module 200.

[0057] According to some embodiments of the present invention, such as Figure 7 As shown, the corner protector device 100 further includes: a third corner protector body 30, the first corner protector body 10 and the third corner protector body 30 are arranged along a first plane, the third corner protector body 30 has an adjacent first side edge 31 and a second side edge 32, a first sub-corner protector body 11 is fixed to the first side edge 31, a second sub-corner protector body 12 is fixed to the second side edge 32 and along a direction perpendicular to the first plane, the third corner protector body 30 is located at the middle position of the first corner protector body 10.

[0058] Among them, such as Figure 4 The diagram shown is a structural schematic of the corner protector device of the fourth embodiment provided in this application. The first sub-corner protector body 11, the second sub-corner protector body 12 and the third corner protector body 30 can be integrally formed. The integral forming eliminates the seams, gaps or weak points in the traditional multi-part assembly, making the overall structure of the corner protector device 100 more stable and avoiding stress concentration caused by seams or connection points, thereby improving the impact resistance and deformation resistance of the corner protector device 100. The plane on which the third corner protector body 30 is located is the first plane. Along a direction perpendicular to the first plane, the third corner protector body 30 is positioned at the middle of the first corner protector body 10, so that the third corner protector body 30 and the second sub-corner protector body 12 define a semi-"I" shape (i.e., a "T" shape). The third corner protector body 30 and the first sub-corner protector body 11 also define a semi-"I" shape (i.e., a "T" shape). Furthermore, the third corner protector body 30, the second sub-corner protector body 12, and the first sub-corner protector body 11 together define two mounting spaces 14 along a direction perpendicular to the first plane, for simultaneously mounting the corners of the two frame pieces 201. This reduces the installation complexity of the corner protector device 100, improves work efficiency, reduces labor costs, and also reduces material usage, thus lowering the manufacturing cost of the corner protector device 100. It should be noted that the middle position of the first corner protector body 10 refers to the position between the two ends of the first corner protector body 10 along a direction perpendicular to the first plane.

[0059] According to some embodiments of the present invention, the corner protector 100 can be constructed as an integral molded part. In some embodiments of the present invention, the corner protector 100 can be formed by integral extrusion molding, integral injection molding, integral flow extension molding, integral blow molding and other molding processes. The present invention takes the corner protector 100 using integral extrusion molding process as an example for explanation. The shape of the extruded product can be changed by adjusting the shape of the die to adapt to different packaging requirements.

[0060] One-piece molding eliminates the seams, gaps, or weak points that may exist in traditional multi-part assembly, making the overall structure of the corner protector 100 more stable and avoiding stress concentration caused by seams or connection points. This improves the impact resistance and deformation resistance of the corner protector 100. One-piece molding technology can complete the manufacturing of complex structures in one molding process without subsequent assembly, reducing the time for multi-part processing, assembly, and testing, and significantly improving the production efficiency of the corner protector 100.

[0061] According to some embodiments of this utility model, the material density of the corner protector 100 is P, and P satisfies the relationship: 0.7 g / cm³. 3 ≤P≤1.2g / cm 3 Specifically, the corner protector 100 is made of an elastomer, and the density of the elastomer can be 0.7 g / cm³. 3 0.8g / cm 3 0.9g / cm 3 1.2g / cm 3 The density of the elastomer can be 0.7 g / cm³, but this invention is not limited to this value. 3 -1.2g / cm 3 Other values ​​between these ranges set the density range of the elastomer at 0.7 g / cm³. 3 -1.2g / cm 3 Within the range, it can maintain sufficient mechanical strength to meet protection requirements while significantly reducing the weight of the corner protector 100. It avoids structural fragility due to excessive weight reduction, absorbs energy through deformation, and does not have insufficient rebound due to excessive softness, ensuring that it can maintain cushioning performance after long-term use.

[0062] Furthermore, the thickness of the corner protector 100 is H, where H satisfies the relationship: 3mm ≤ H ≤ 20mm. Specifically, the value of the thickness H of the corner protector 100 is between 3mm and 20mm. In some embodiments of this utility model, the thickness H of the corner protector 100 can be 3mm, 4mm, 5mm, 6mm, 7mm, 10mm, 20mm, etc., but this utility model is not limited to these values. The thickness H of the corner protector 100 can also be other values ​​between 3mm and 20mm, as long as the thickness H of the corner protector 100 satisfies the relationship: 3mm ≤ H ≤ 20mm. The thickness of the corner protector 100 directly affects its impact resistance. Setting the thickness H of the corner protector 100 between 3mm and 20mm can not only meet the requirements of the corner protector 100 to absorb and disperse external impact forces and reduce damage to the protected object, but also appropriately reduce the amount of material used in the corner protector 100, reduce the production cost of the corner protector 100, reduce the weight of the corner protector 100, and reduce the transportation difficulty of the photovoltaic module 200.

[0063] Furthermore, such as Figure 1 and Figure 2 The diagram shown is a structural schematic of the corner protector 100 according to the first embodiment of the present invention. The corner protector 100 includes a first corner protector body 10, which includes a first sub-corner protector body 11 and a second sub-corner protector body 12. The first sub-corner protector body 11 and the second sub-corner protector body 12 are bent and connected and perpendicular to each other to define an "L"-shaped or similar "L"-shaped corner protector 100. This can effectively protect the photovoltaic module 200, reduce the risk of abnormalities such as frame deformation and panel bursting of the photovoltaic module 200 during transportation, and also reduce the scratches on the corners 202 of the photovoltaic module 200 to the installers during installation.

[0064] like Figure 3 and Figure 4The diagram shows a structural schematic of a corner protector device 100 according to a second embodiment of the present invention. The corner protector device 100 includes a first corner protector body 10, which comprises a first sub-corner protector body 11, a second sub-corner protector body 12, and a connecting body 13. The connecting body 13 connects the first sub-corner protector body 11 and the second sub-corner protector body 12, allowing them to bend and connect. The connecting body 13 is arc-shaped to define an installation space 14 for mounting the corner 202, thus defining a "C"-shaped corner protector device 100. The arc-shaped structure can evenly distribute external impact force or bending stress across the entire arc surface, avoiding local stress concentration (such as stress peaks easily generated by right-angle connections), thereby improving the overall structural strength of the corner protector device 100. The arc transition reduces fatigue damage to the material under repeated stress. When subjected to force, the arc-shaped connecting body 13 can achieve elastic deformation through arc surface compression or stretching, absorbing more impact energy, enhancing the shock absorption effect, and effectively extending the service life of the connecting body 13.

[0065] like Figure 5 and Figure 6 The diagram shown is a structural schematic of the corner protector device 100 according to the third embodiment of the present invention. The corner protector device 100 includes: a first corner protector body 10 and a second corner protector body 20. The first corner protector body 10 includes: a first sub-corner protector body 11 and a second sub-corner protector body 12. The second corner protector body 20 includes: a third sub-corner protector body 21 and a fourth sub-corner protector body 22. The third sub-corner protector body 21 and the fourth sub-corner protector body 22 are bent and connected. The third sub-corner protector body 21 and the first sub-corner protector body 11 are correspondingly connected. The fourth sub-corner protector body 22 and the second sub-corner protector body 12 are correspondingly connected. Both the third sub-corner protector body 21 and the fourth sub-corner protector body 22 include a straight section 24 and an arc-shaped section 25. The two end faces of the straight section 24 and the arc-shaped section 25 are fixedly connected to define a buffer space 23. The side of the straight section 24 away from the arc-shaped section 25 is the outer side of the second corner protector body 20. The first sub-corner protector body 11 and the second sub-corner protector body 12 both extend along the edge of the straight section 24 of the second corner protector body 20 to construct an "e"-shaped triangular load-bearing structure for mounting the corners 202 of the frame 201. The corner protector 23 forms a multi-directional wrap around the corners 202 of the frame 201 of the photovoltaic module 200, reducing blind spots. When the photovoltaic module 200 is impacted, the buffer space 23 can act as a first-level buffer layer, deforming first when subjected to external impact to absorb some energy. Subsequently, the elastomeric material of the corner protector 100 acts as a second-level buffer layer to further disperse the remaining energy, enabling the corner protector 100 to maintain efficient protection under different impact velocities, thereby further improving the protective effect of the corner protector 100.

[0066] like Figure 7The diagram shown is a structural schematic of the corner protector device according to the fourth embodiment of the present invention. The corner protector device 100 includes: a third corner protector body 30, a first corner protector body 10 and the third corner protector body 30 arranged along a first plane, the third corner protector body 30 having adjacent first side edge 31 and second side edge 32, a first sub-corner protector body 11 fixed to the first side edge 31, a second sub-corner protector body 12 fixed to the second side edge 32 and along a direction perpendicular to the first plane, and the third corner protector body 30 located at the middle position of the first corner protector body 10. The plane on which the third corner protector body 30 is located is the first plane. Along a direction perpendicular to the first plane, the third corner protector body 30 is positioned at the middle of the first corner protector body 10, so that the third corner protector body 30 and the second sub-corner protector body 12 define a semi-"I" shape (i.e., a "T" shape). The third corner protector body 30 and the first sub-corner protector body 11 also define a semi-"I" shape (i.e., a "T" shape). Furthermore, the third corner protector body 30, the second sub-corner protector body 12, and the first sub-corner protector body 11 together define two mounting spaces 14 along a direction perpendicular to the first plane, for simultaneously mounting the corners of the two frame pieces 201. This reduces the installation complexity of the corner protector device 100, improves work efficiency, reduces labor costs, and also reduces material usage, thus lowering the manufacturing cost of the corner protector device 100. It should be noted that the middle position of the first corner protector body 10 refers to the position between the two ends of the first corner protector body 10 along a direction perpendicular to the first plane.

[0067] Furthermore, the packaging of the photovoltaic module 200, from the inside out, consists of: photovoltaic module 200, corner protector 100, and packaging box. The packaging box for the photovoltaic module 200 can be an airplane box, a snap-fit ​​box, a top-and-bottom box, a drawer-type box, etc. The material used for the packaging box can be corrugated cardboard, and the corrugated shape can include A-flute, B-flute, C-flute, etc. Through the combined use of the corner protector 100 and the packaging box, this invention can be used for individual packaging of the photovoltaic module 200 during long-distance transportation. It can effectively resist damage to the photovoltaic module 200 caused by drops from a height due to handling, bumps, or other reasons during the process, effectively reducing the damage rate of the photovoltaic module 200 during transportation, and lowering the transportation cost and difficulty.
