[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0026] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0029] Existing products often feature chamfered edges at their ends for reasons such as personal protection (reducing the risk of cuts to hands or other parts from sharp edges during handling and assembly), product protection (eliminating stress at sharp points through chamfering), and ease of assembly (facilitating insertion into mounting holes or connection with other components). These chamfers can be rounded or beveled. However, existing corner protectors for such products have a small contact area with the product, easily creating blind spots or potential deformation hazards.

[0030] Based on this, an embodiment of this utility model proposes a corner protector for supporting and protecting the chamfered ends of the product 6. For example, the corner protector can be used for photovoltaic modules. Figures 1-5 As shown, the corner protector proposed in the embodiment of this utility model includes a first support part 1, a second support part 2, and a third support part 3. The first support part 1 and the second support part 2 are arranged at an angle. The first support part 1 is used to protect one side of the corner of the product 6. The second support part 2 is connected to the first support part 1 and is used to protect the other side of the corner of the product 6. The third support part 3 is connected between the first support part 1 and the second support part 2, and the third support part 3 has a support surface 31 that is arranged at an angle to both the first support part 1 and the second support part 2. The support surface 31 can abut against the chamfer of the product 6.

[0031] When the aforementioned corner protector is applied to product 6 with chamfered ends, the first support part 1 is attached to one side of the corner of product 6, the second support part 2 is attached to the other side of the corner of product 6, and the third support part 3 abuts against the chamfer of product 6, forming a stable triangular structure. This fully utilizes the stability advantage of triangles in mechanical structures and enhances the corner protector's ability to disperse and absorb external impact forces.

[0032] Specifically, both the first support part 1 and the second support part 2 are constructed as plate-like structures to better fit the product 6, enabling them to more reliably protect the product 6. The third support part 3 is configured as a triangular prism structure, with one side of the third support part 3 fitting against the first support part 1, another side fitting against the second support part 2, and the remaining side serving as the support surface 31. The third support part 3 effectively fills the structural gap between the chamfer and corner protector of the product 6, thereby enhancing its support for the product 6. Since adjacent corners of the existing product 6 are typically set at 90 degrees, in this embodiment, the first support part 1 and the second support part 2 are perpendicular to each other, while the third support part 3 adopts an isosceles right triangle cross-section. It is understood that the size of the third support part 3 can be flexibly adjusted according to the chamfer of different products 6 to accommodate packaging products 6 with varying chamfer sizes, thus broadening the application range of corner protectors in industries such as new energy, home appliances, and building materials.

[0033] In this embodiment, the corner protector is made of cardboard 5 with appropriate strength and toughness, such as vertical corrugated cardboard or honeycomb cardboard. The thickness and strength of the cardboard 5 are determined according to the actual application requirements. The third support part 3 is bonded to the first support part 1 and the second support part 2 with environmentally friendly adhesive. The entire corner protector is green, biodegradable, and easy to recycle, meeting the international market's environmental requirements for sustainable and recyclable packaging, and contributing to the export of enterprise products and the establishment of a brand's environmental image.

[0034] Specifically, the first support part 1 and the second support part 2 are integrally bent from the same cardboard 5 to reduce processing difficulty. More specifically, any corner protector is formed by die-cutting from the same cardboard 5. By cutting the cardboard 5, a V-shaped groove 51 is formed, so that when folded along the V-shaped groove 51, the two inclined surfaces of the V-shaped groove 51 fit together to form the first support part 1 and the second support part 2 at an angle. The cut-off part is fixed between the first support part 1 and the second support part 2 as the third support part 3, thereby reducing the processing cost of the corner protector. That is, the first support part 1 and the second support part 2 unfold into a cardboard 5 with a V-shaped groove 51, and the shape and size of the third support part 3 are the same as those of the V-shaped groove 51.

[0035] Obviously, at this time, the length L3 of the third support 3 is the same as the length L1 of the first support 1 and the length L2 of the second support 2. When the third support 3 is assembled onto the first support 1 and the second support 2, neither end of the length of the third support 3 protrudes beyond the first support 1 and the second support 2, so as to avoid the third support 3 occupying extra space. The length and width of the first support 1 and the second support 2 are adaptively selected according to the size of the product 6 to maximize the contact area with the product 6, without specific restrictions. It is understood that the width of the first support 1 and the width of the second support 2 are not necessarily the same.

[0036] Taking the first support part 1 and the second support part 2 as an example where they are vertically aligned, the two inclined sides of the V-groove 51 form an angle of 45° with the plane of the cardboard 5. It is worth noting that when cutting the V-groove 51, the depth and width of the V-groove 51 need to be precisely controlled to ensure good forming effect after folding along the V-groove 51 and to avoid the cardboard 5 from breaking.

[0037] Of course, the third support part 3 can also be made separately according to the chamfer size of the product 6. In this case, the length of the third support part 3 is the same as the length of the first support part 1 and the second support part 2, and it does not protrude from the first support part 1 and the second support part 2, so as to maximize the contact area between the third support part 3 and the product 6 while avoiding the third support part 3 taking up extra space.

[0038] The first support part 1, the second support part 2, and the third support part 3 together constitute the corner protector body. To reduce the friction between the corner protector and the product 6, the corner protector also includes a face paper 4, which covers the side of the corner protector body facing the product 6. The face paper 4 increases the surface smoothness of the corner protector and also enhances its overall aesthetics. Specifically, the face paper 4 can be fixed to the first support part 1, the second support part 2, and the third support part 3 by adhesive bonding, or the face paper 4 can be directly sandwiched between the corner protector body and the product 6, allowing for selective use of the face paper 4. More specifically, the face paper 4 is not limited to kraft paper.

[0039] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
