Corner guards for a photovoltaic module frame

Abstract

This application relates to the field of photovoltaic module packaging technology, and more particularly to a corner protector for a photovoltaic module frame. The frame has corners, and the corner protector covers these corners. The corner protector includes a lower protector plate, a connecting protector plate, an upper protector plate, and an anti-detachment protector plate. The lower protector plate covers the front of the corner, the connecting protector plate is connected to the lower protector plate and covers the outer side of the corner, and the upper protector plate is connected to the connecting protector plate and covers the back of the corner. A receiving groove is provided between the upper protector plate, the connecting protector plate, and the lower protector plate. The anti-detachment protector plate is connected to the upper protector plate and can be bent towards the receiving groove to the inside of the frame. A portion of the anti-detachment protector plate's structure is designed to abut against the inner side of the corner. By providing the anti-detachment protector plate, and ensuring that a portion of its structure abuts against the inside of the frame, this application restricts the movement of the anti-detachment protector plate, thereby preventing the corner protector from detaching from the corner of the frame. This ensures the corner protector is firmly wrapped around the corner, improving the stability of the corner protector after installation and reducing the risk of the corner protector falling off during transportation.

Description

Technical Field

[0001] This application relates to the field of photovoltaic module packaging technology, and in particular to a corner protector for a photovoltaic module frame. Background Technology

[0002] During the transportation of photovoltaic modules, multiple photovoltaic modules need to be stacked along their own thickness direction and then placed into a packaging box. The packaging box and photovoltaic modules are then packed and secured to enable the handling of multiple modules at once and improve transportation efficiency.

[0003] The photovoltaic modules stand upright in the packaging box along their length or width. Therefore, the surface of the module's frame will be subject to friction during packaging and transportation. To prevent wear defects on the surface of the module's frame, corner protectors are installed at the corners of the module. The corner protectors wrap around the corners to separate adjacent modules inside the packaging.

[0004] When the outline of the frame is irregular, it is easy for the corner protector to not fit tightly with the frame, and there is a risk of the corner protector separating from the component during packaging and transportation. Summary of the Invention

[0005] This application provides a corner protector for a photovoltaic module frame, designed to reduce the risk of the corner protector falling off during transportation.

[0006] This application provides a corner protector for a photovoltaic module frame. The frame has corner portions, and the corner protector is used to cover the corner portions. The corner protector includes:

[0007] The lower guard plate is used to cover the front of the corner.

[0008] A connecting guard plate is connected to the lower guard plate and is used to cover the outer side of the corner.

[0009] An upper protective plate, connected to the connecting protective plate, is used to cover the back of the corner portion, and a receiving groove is provided between the upper protective plate, the connecting protective plate, and the lower protective plate;

[0010] An anti-detachment guard plate is connected to the upper guard plate. The anti-detachment guard plate can be bent toward the inside of the frame in the direction of the receiving groove, and part of the structure of the anti-detachment guard plate is used to abut against the inner side of the corner.

[0011] In one possible design, the upper protective panel includes a first upper panel and a second upper panel, the first upper panel and the second upper panel being spliced ​​together to cover the back of the corner;

[0012] Both the first upper panel and the second upper panel are connected to the anti-detachment protective plate.

[0013] In one possible design, the anti-detachment guard plate connected to the first upper panel includes a first anti-detachment panel and a second anti-detachment panel;

[0014] The first anti-detachment panel and the second anti-detachment panel are bent in sequence. The first anti-detachment panel can be bent into the receiving groove, and the second anti-detachment panel can be bent to abut against the surface of the photovoltaic module.

[0015] The anti-detachment guard plate connected to the second upper panel includes a third anti-detachment panel and a fourth anti-detachment panel;

[0016] The third anti-detachment panel and the fourth anti-detachment panel are bent in sequence. The third anti-detachment panel can be bent into the receiving groove, and the fourth anti-detachment panel can be bent to abut against the surface of the photovoltaic module.

[0017] The first anti-detachment panel is attached to the third anti-detachment panel, and the second anti-detachment panel and the fourth anti-detachment panel are bent in a direction away from each other.

[0018] In one possible design, the first upper panel has a snap-fit ​​hole on the side near the first anti-detachment panel, and the third anti-detachment panel has a snap-fit ​​part on the side near the second upper panel.

[0019] The snap-fit ​​portion can be bent to snap into the snap-fit ​​hole.

[0020] In one possible design, along the thickness direction of the corner protector, a portion of the snap-fit ​​portion can extend beyond the snap-fit ​​hole into the receiving groove to abut against the inner surface of the corner.

[0021] In one possible design, the upper guard plate includes a first upper panel and a second upper panel, with a portion of the first upper panel overlapping a portion of the second upper panel;

[0022] The first upper panel is connected to the anti-detachment protective plate.

[0023] In one possible design, the anti-detachment guard plate includes a first anti-detachment panel and a second anti-detachment panel;

[0024] The first anti-detachment panel and the second anti-detachment panel are bent in sequence. The first anti-detachment panel can be bent into the receiving groove, and the second anti-detachment panel can be bent to fit against the surface of the photovoltaic module.

[0025] In one possible design, the first upper panel is provided with a snap-fit ​​hole, and the second upper panel is connected to a snap-fit ​​part on the side away from the connecting guard plate;

[0026] The snap-fit ​​portion can be bent to snap into the snap-fit ​​hole.

[0027] In one possible design, along the thickness direction of the corner protector, a portion of the snap-fit ​​portion can extend beyond the snap-fit ​​hole into the receiving groove to abut against the inner surface of the corner.

[0028] In one possible design, the connecting guard plate includes a first connecting panel and a second connecting panel, the first connecting panel and the second connecting panel being connected to two sides of the lower guard plate, respectively.

[0029] The first connecting panel is connected to the first upper panel, and the second connecting panel is connected to the second upper panel.

[0030] In this application, the corner structure of the frame is protected by setting an upper guard plate, a connecting guard plate and a lower guard plate to prevent the frame from being worn during transportation.

[0031] The main feature of this application is that by setting an anti-detachment guard, a portion of the guard's structure can be bent to the inside of the frame. During transportation, when the corner protector moves relative to the frame under external force, the portion of the anti-detachment guard can abut against the inside of the frame, restricting its movement and preventing the corner protector from detaching from the corner of the frame. This ensures the corner protector is firmly wrapped around the corner, improving its stability after installation and reducing the risk of it falling off during transportation.

[0032] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

[0083] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0084] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0085] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0086] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0087] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0088] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0089] like Figure 1 The diagram shown is a schematic of the cooperation between the frame and the photovoltaic module in the prior art, including the frame 20′ and the photovoltaic module 10′. The frame 20′ is set around the photovoltaic module 10′ to protect the edge of the photovoltaic module 10′, enhance the sealing performance of the photovoltaic module 10′, and improve the mechanical strength of the photovoltaic module 10′.

[0090] The frame 20′ has corners. To prevent the corners of the frame 201′ from being damaged during packaging and transportation, corner guards 30′ will be installed at the corners 201′.

[0091] like Figure 2 The diagram shown is a schematic diagram of the structure of a corner protector in the prior art. The corner protector 30′ is provided with a receiving groove 301′, which is used to receive the corner 201′ of the frame 20′.

[0092] like Figure 3 The diagram shown illustrates the fit between the corner protectors and the frame in existing technology. Please refer to it for further information. Figures 1 to 3 The corner protector 30′ is fitted onto the corner 201′ of the frame 20′. The corner 201′ of the frame 20′ is located within the receiving groove 301′. The two side walls of the corner protector 30′ are tightly fitted to the two side walls of the frame 20′ that are perpendicular to each other. The top wall of the corner protector 30′ is tightly fitted to the top wall of the frame 20′, and the bottom wall of the corner protector 30′ is tightly fitted to the bottom wall of the frame 20′.

[0093] However, when the outline of the border is an irregular structure, Figure 2 The corner protectors shown may not fit snugly against the irregular border.

[0094] For example, such as Figure 4The diagram shows a partial cross-sectional view of a frame 3 with an irregular profile that mates with a photovoltaic module 2, including the frame 3 and the photovoltaic module 2. The frame 3 includes a front side 31, a back side 33, an inner side 34, and an outer side 32. The inner side 34 includes a first inner side 341 and a second inner side 342. Along the thickness direction Z of the frame 3, the first inner side 341 is located below the frame 3, and the second inner side 342 is located above the frame 3. The outer side 32 includes a first outer side 321 and a second outer side 322. Along the thickness direction Z of the frame 3, the second outer side 322 is located above the first outer side 321, and along the width direction Y of the frame 3, the second outer side 322 is closer to the photovoltaic module 2 than the first outer side 321.

[0095] Along the width Y direction of border 3, there is a gap between the first outer side 321 and the second outer side 322, which can be used as follows: Figure 2 When the conventional corner protector shown is fitted with this type of irregular frame, there will be a cavity between the corner protector and the frame 3, which will result in the corner protector not fitting tightly to the frame 3, and there is a risk of separation during transportation.

[0096] To address this issue, this embodiment provides corner protectors 1 for the photovoltaic module frame 3.

[0097] like Figure 5 The diagram shows a folded corner protector 1 in one specific embodiment. The corner protector 1 is used to cover the corner of the frame 3. The corner protector 1 includes a lower protective plate 11, a connecting protective plate 12, an upper protective plate 13, and an anti-detachment protective plate 15, all of which are integrally structured. The connecting protective plate 12 is connected to the lower protective plate 11, the upper protective plate 13 is connected to the connecting protective plate 12, and the anti-detachment protective plate 15 is connected to the upper protective plate 13.

[0098] The lower guard plate 11 is roughly triangular in shape. The lower guard plate 11 can cover the front side 31 of the corner. The connecting guard plate 12 can cover the outer side 32 of the corner. The upper guard plate 13 can cover the back side 33 of the corner. The upper guard plate 13, the connecting guard plate 12 and the lower guard plate 11 together form a receiving groove 14. The anti-detachment guard plate 15 can be bent towards the receiving groove 14 to the inside of the frame 3, and part of the structure of the anti-detachment guard plate 15 is used to abut against the inner side 34 of the corner.

[0099] When the staff uses the corner protector 1 to cover the frame 3, the frame 3 is placed upside down on the workbench with the back 33 of the frame 3 facing up. The corner protector 1, which is in the unfolded state, is folded while it is in the position of fitting the corner, rather than folding the corner protector 1 first and then putting it on the corner.

[0100] In this embodiment, the corner structure of the frame 3 is wrapped by the upper protective plate 13, the connecting protective plate 12 and the lower protective plate 11 to protect the corner position and prevent the frame 3 from being worn during transportation.

[0101] Mainly, this embodiment incorporates an anti-detachment guard plate 15, allowing a portion of its structure to bend to the inside of the frame 3. During transportation, when the corner protector 1 moves relative to the frame 3 under external force, a portion of the anti-detachment guard plate 15 abuts against the inside of the frame 3, restricting its movement and preventing the corner protector 1 from detaching from the corner of the frame 3. This ensures the corner protector 1 is securely wrapped around the corner, improving its stability after installation and reducing the risk of it falling off during transportation.

[0102] The corner protector 1 provided in this embodiment can be applied to various frame structures 3 with regular or irregular contours, which will not be described in detail here. The following section describes the corner protector 1 being fitted onto... Figure 4 Let's take the irregular border 3 as an example to illustrate.

[0103] Please refer to the reference. Figure 4 and Figure 5 When the protective plate covers the corner, the lower protective plate 11 fits tightly against the front 31, the connecting protective plate 12 fits tightly against the first outer side 321, and there is a gap between the connecting protective plate 12 and the second outer side 322. The upper protective plate 13 fits tightly against the back 33, and the anti-detachment protective plate 15 is located on the inside of the first inner side 341 (the side away from the first outer side 321 along the width direction Y of the frame 3). Although there is a certain gap between the connecting protective plate 12 and the second outer side 322, which may result in them not fitting tightly together and potentially causing the protective plate to detach from the corner, the anti-detachment protective plate 15 is folded to the inside of the first inner side 341 of the frame 3, thus preventing the protective plate from detaching. Even if the protective plate moves due to external force, the anti-detachment protective plate 15 will move to abut against the first inner side 341, and the first inner side 341 restricts the movement of the anti-detachment protective plate 15, thereby preventing the protective plate from falling off.

[0104] The following text combines Figure 5 The schematic diagram showing the folded state of corner protector 1 illustrates the specific structure of corner protector 1 and its relationship with... Figure 4 The fit of the border 3 shown.

[0105] Please continue to refer to the reference. Figure 4 and Figure 5 The connecting guard plate 12 includes a first connecting panel 121 and a second connecting panel 122, and the first connecting panel 121 and the second connecting panel 122 are respectively tightly fitted to two first outer side surfaces 321 that are approximately perpendicular to the corner.

[0106] The upper protective plate 13 includes a first upper panel 131 and a second upper panel 132, which are spliced ​​together and cover the back 33 of the corner. Both the first upper panel 131 and the second upper panel 132 are connected to anti-detachment protective plates 15.

[0107] In this embodiment, by setting two anti-detachment guard plates 15, the overall structural strength of the anti-detachment guard plate 15 is improved, thereby increasing the anti-detachment ability of the anti-detachment guard plate 15 and further reducing the risk of the corner protector 1 falling off.

[0108] Furthermore, the splicing position of the first upper panel 131 and the second upper panel 132 can be located at the angle bisector of the corner, so that both the first upper panel 131 and the second upper panel 132 can provide space for the folding of the anti-detachment guard plate 15.

[0109] Meanwhile, by setting the splicing position of the first upper panel 131 and the second upper panel 132 at the bisector of the corner, the anti-detachment guard plate 15 is located at the extension position of the bisector of the corner, so that the anti-detachment guard plate 15 can abut against the two adjacent and approximately perpendicular first inner side surfaces 341 on the frame 3, thereby restricting the corner protector 1 from falling off along the width direction Y and length direction X of the frame 3.

[0110] Please continue to refer to the reference. Figure 4 and Figure 5 The anti-detachment guard plate 15 connected to the first upper panel 131 includes a first anti-detachment panel 151 and a second anti-detachment panel 152, which are bent sequentially. The first anti-detachment panel 151 can be bent into the receiving groove 14 and is used to abut against the first inner side surface 341 to prevent the corner protector 1 from falling off. The second anti-detachment panel 152 can be bent to abut against the surface of the photovoltaic module and is able to abut against the surface (back side 33) of the photovoltaic module, providing support for the corner protector 1 and improving the structural stability of the corner protector 1 after folding.

[0111] The anti-detachment guard plate 15 connected to the second upper panel 132 includes a third anti-detachment panel 153 and a fourth anti-detachment panel 154, which are bent sequentially. The third anti-detachment panel 153 can be bent into the receiving groove 14 and is used to abut against the first inner side surface 341 to prevent the corner protector 1 from falling off. The fourth anti-detachment panel 154 can be bent to abut against the surface of the photovoltaic module 2 and the back surface 33 of the photovoltaic module 2, providing support for the corner protector 1 and improving the structural stability of the corner protector 1 after folding.

[0112] In this embodiment, the first anti-detachment panel 151 and the third anti-detachment panel 153 are attached together, while the second anti-detachment panel 152 and the fourth anti-detachment panel 154 are bent in a direction away from each other. By attaching the first anti-detachment panel 151 and the third anti-detachment panel 153 together, the contact force of the anti-detachment protective plate 15 is increased, further reducing the risk of the corner protector 1 detaching. By limiting the bending of the second anti-detachment panel 152 and the fourth anti-detachment panel 154 in a direction away from each other, the contact area between the anti-detachment protective plate 15 and the surface of the photovoltaic module is increased, further enhancing the support effect on the corner protector 1.

[0113] Please continue to refer to the reference. Figure 4 and Figure 5 The first upper panel 131 is provided with a snap-fit ​​hole 131a on the side near the first anti-detachment panel 151, and the third anti-detachment panel 153 is provided with a snap-fit ​​part 153a on the side near the second upper panel 132. The snap-fit ​​part 153a can be bent to snap into the snap-fit ​​hole 131a, thereby completing the self-locking of the corner protector 1 and making the corner protector 1 firmly wrapped around the corner.

[0114] Alternatively, a snap-fit ​​hole 131a may be provided on the side of the second upper panel 132 near the second anti-detachment panel 152, and a snap-fit ​​part 153a may be provided on the side of the first anti-detachment panel 151 near the first upper panel 131, the snap-fit ​​part 153a being able to be bent to snap into the snap-fit ​​hole 131a.

[0115] Furthermore, along the thickness direction Z of the corner protector 1, a portion of the snap-fit ​​portion 153a can extend out of the snap-fit ​​hole 131a into the receiving groove 14 and fit against the first anti-detachment panel 151 to abut against the first inner side surface 341 of the corner, thereby increasing the anti-detachment effect of the corner protector 1.

[0116] The snap-fit ​​part 153a can be a semi-circular structure, and the diameter of the snap-fit ​​part 153a is the same as the width of the snap-fit ​​hole 131a, so that the snap-fit ​​part 153a can be inserted into the snap-fit ​​hole 131a and the two can be snapped together at the same time.

[0117] like Figure 6 The diagram shown is a schematic representation of the unfolded state of the corner protector 1 in a specific embodiment. The following text, in conjunction with... Figure 6 This section describes the specific steps involved in wrapping the corner protector 1 around the frame 3.

[0118] The corner protector 1 includes a lower protective plate 11, a first connecting panel 121, a second connecting panel 122, a first upper panel 131, a second upper panel 132, a first anti-detachment panel 151, a second anti-detachment panel 152, a third anti-detachment panel 153, a fourth anti-detachment panel 154, a snap-fit ​​part 153a, and a snap-fit ​​hole 131a. Each panel has a crease 16, which can be a perforated fold line to facilitate bending along the crease 16 by the worker.

[0119] Specifically, the first connecting panel 121 and the second connecting panel 122 are respectively connected to two sides of the lower guard plate 11 that are approximately perpendicular to each other. Furthermore, there is a first crease 161 between the first connecting panel 121 and the lower guard plate 11, and a second crease 162 between the second connecting panel and the lower guard plate 11.

[0120] The first upper panel 131 is connected to the first connecting panel 121, and the second upper panel 132 is connected to the second connecting panel 122. Furthermore, there is a third crease 163 between the first upper panel 131 and the first connecting panel 121, and a fourth crease 164 between the second upper panel 132 and the second connecting panel 122.

[0121] The first anti-detachment panel 151 is connected to the side of the first upper panel 131 away from the first connecting panel 121.

[0122] The second anti-detachment panel 152 is connected to the side of the first anti-detachment panel 151 away from the first upper panel 131. Furthermore, there is a fifth crease 165 between the first anti-detachment panel 151 and the first upper panel 131, and a sixth crease 166 between the second anti-detachment panel 152 and the first anti-detachment panel 151.

[0123] The third anti-detachment panel 153 is connected to the side of the second upper panel 132 away from the second connecting panel 122.

[0124] The fourth anti-detachment panel 154 is connected to the third anti-detachment panel 153 on the side away from the second upper panel 132. Furthermore, there is a seventh crease 167 between the third anti-detachment panel 153 and the second upper panel 132, and an eighth crease 168 between the fourth anti-detachment panel 154 and the third anti-detachment panel 153.

[0125] The snap-fit ​​hole 131a is a hole structure cut from the first upper panel 131, and the snap-fit ​​part 153a is a semi-circular structure cut from the third anti-detachment panel 153. Specifically, no perforation crease is provided at the connection position between the snap-fit ​​part 153a and the seventh crease 167 to prevent the snap-fit ​​part 153a from falling off. No perforation crease is provided at the connection position between the snap-fit ​​hole 131a and the fifth crease 165 to prevent the snap-fit ​​hole 131a from cracking along the perforation crease, thus affecting the snap-fit ​​effect between the snap-fit ​​part 153a and the snap-fit ​​hole 131a.

[0126] Please refer to the reference. Figure 4 and Figure 6 The steps for the corner protector 1 to wrap around the corner of the frame 3 are as follows: First, place the lower protector 11 under the frame 3 and attach it to the front side 31 of the corner. Bend the first connecting panel 121 upward along the first crease 161 and the second connecting panel 122 upward along the second crease 162, so that the first connecting panel 121 and the second connecting panel 122 are respectively attached to the two first outer sides 321 that are approximately perpendicular to each other in the corner.

[0127] Then, the first upper panel 131 is bent along the third crease 163, so that the first upper panel 131 is attached to the back side 33 of the corner. At the same time, the first anti-detachment panel 151 is bent downward along the fifth crease 165, and the second anti-detachment panel 152 is bent towards the first upper panel 131 along the sixth crease 166, so that the first anti-detachment panel 151 is folded to the inside of the first inner side 341, and the second anti-detachment panel 152 is folded to be attached to the surface of the photovoltaic module.

[0128] Next, bend the second upper panel 132 along the fourth crease 164 so that the second upper panel 132 fits against the back side 33 of the corner. At the same time, bend the third anti-detachment panel 153 downward along the seventh crease 167. At this time, place the snap-fit ​​part 153a on the first upper panel 131, and bend the fourth anti-detachment panel 154 towards the second upper panel 132 along the eighth crease 168 so that the third anti-detachment panel 153 is folded to the inside of the first inner side 341, and the fourth anti-detachment panel 154 is folded to fit against the surface of the photovoltaic module.

[0129] Finally, the snap-fit ​​part 153a is bent into the snap-fit ​​hole 131a to achieve the connection and fixation of the corner protector 1, as shown. Figure 7 As shown.

[0130] like Figure 8 The diagram shown is a structural schematic of the corner protector 1 in a folded state in another specific embodiment. The corner protector 1 covers the corner of the frame 3. The corner protector 1 includes a lower protective plate 11, a connecting protective plate 12, an upper protective plate 13, and an anti-detachment protective plate 15, all of which are integral structures. The connecting protective plate 12 is connected to the lower protective plate 11, the upper protective plate 13 is connected to the connecting protective plate 12, and the anti-detachment protective plate 15 is connected to the upper protective plate 13.

[0131] The lower guard plate 11 is roughly triangular in shape. The lower guard plate 11 can cover the front side 31 of the corner. The connecting guard plate 12 can cover the outer side 32 of the corner. The upper guard plate 13 can cover the back side 33 of the corner. The upper guard plate 13, the connecting guard plate 12 and the lower guard plate 11 together form a receiving groove 14. The anti-detachment guard plate 15 can be bent towards the receiving groove 14 to the inside of the frame 3, and part of the structure of the anti-detachment guard plate 15 is used to abut against the inner side 34 of the corner.

[0132] When the staff uses the corner protector 1 to cover the frame 3, the frame 3 is placed upside down on the workbench with the back 33 of the frame 3 facing up. The corner protector 1, which is in the unfolded state, is folded while it is in the position of fitting the corner of the frame 3, rather than folding the corner protector 1 first and then putting it on the corner.

[0133] In this embodiment, the corner structure of the frame 3 is wrapped by the upper protective plate 13, the connecting protective plate 12 and the lower protective plate 11 to protect the corner position and prevent the frame 3 from being worn during transportation.

[0134] Mainly, this embodiment incorporates an anti-detachment guard plate 15, allowing a portion of its structure to bend to the inside of the frame 3. During transportation, when the corner protector 1 moves relative to the frame 3 under external force, a portion of the anti-detachment guard plate 15 abuts against the inside of the frame 3, restricting its movement and preventing the corner protector 1 from detaching from the corner of the frame 3. This ensures the corner protector 1 is securely wrapped around the corner, improving its stability after installation and reducing the risk of it falling off during transportation.

[0135] The corner protector 1 provided in this embodiment can be applied to various frame structures 3 with regular or irregular contours, which will not be described in detail here. The following section describes the corner protector 1 being fitted onto... Figure 4 Let's take the irregular border 3 as an example to illustrate.

[0136] Please refer to the reference. Figure 4 and Figure 8 When the protective plate covers the corner, the lower protective plate 11 fits tightly against the front 31, the connecting protective plate 12 fits tightly against the first outer side 321, and there is a gap between the connecting protective plate 12 and the second outer side 322. The upper protective plate 13 fits tightly against the back 33, and the anti-detachment protective plate 15 is located on the inside of the first inner side 341 (the side away from the first outer side 321 along the width direction Y of the frame 3). Although there is a certain gap between the connecting protective plate 12 and the second outer side 322, which may result in them not fitting tightly together and potentially causing the protective plate to detach from the corner, the anti-detachment protective plate 15 is folded to the inside of the first inner side 341 of the frame 3, thus preventing the protective plate from detaching. Even if the protective plate moves due to external force, the anti-detachment protective plate 15 will move to abut against the first inner side 341, and the first inner side 341 restricts the movement of the anti-detachment protective plate 15, thereby preventing the protective plate from falling off.

[0137] The following text combines Figure 8 The schematic diagram showing the folded state of corner protector 1 illustrates the specific structure of corner protector 1 and its relationship with... Figure 4 The fit of the border 3 shown.

[0138] Please continue to refer to the reference. Figure 4 and Figure 8 The connecting guard plate 12 includes a first connecting panel 121 and a second connecting panel 122, and the first connecting panel 121 and the second connecting panel 122 are respectively tightly fitted to two first outer side surfaces 321 that are approximately perpendicular to the corner.

[0139] The upper guard plate 13 includes a first upper panel 131 and a second upper panel 132. Part of the first upper panel 131 overlaps with part of the second upper panel 132. The first upper panel 131 is connected to an anti-detachment guard plate 15. By setting the anti-detachment guard plate 15, the risk of the corner protector 1 falling off is reduced.

[0140] Furthermore, the area of ​​the second upper panel 132 is smaller than that of the first upper panel 131, so that the splicing position of the first upper panel 131 and the second upper panel 132 is set off at the angle bisector of the corner. Because the anti-detachment guard plate 15 is located on the inside of the first inner side 341, one anti-detachment guard plate 15 can also play an anti-detachment role for the corner protector 1 along the width direction Y and the length direction X.

[0141] Please continue to refer to the reference. Figure 4 and Figure 8 The anti-detachment guard plate 15 includes a first anti-detachment panel 151 and a second anti-detachment panel 152, which are bent sequentially. The first anti-detachment panel 151 can be bent into the receiving groove 14 and is used to abut against the first inner side surface 341 to prevent the corner protector 1 from falling off. The second anti-detachment panel 152 can be bent to fit against the surface of the photovoltaic module and abut against the surface (back side 33) of the photovoltaic module, providing support for the corner protector 1 and improving the structural stability of the corner protector 1 after folding.

[0142] Please continue to refer to the reference. Figure 4 and Figure 8 The first upper panel 131 is provided with a snap-fit ​​hole 131a, and the second upper panel 132 is connected to a snap-fit ​​part 153a on the side away from the connecting guard plate 12. The snap-fit ​​part 153a can be bent to snap into the snap-fit ​​hole 131a, thereby completing the self-locking of the corner protector 1 and making the corner protector 1 firmly wrapped around the corner.

[0143] Furthermore, two snap-fit ​​portions 153a and snap-fit ​​holes 131a can be provided to enhance the snap-fit ​​strength. Along the thickness direction Z of the corner protector 1, a portion of the snap-fit ​​portion 153a can extend out of the snap-fit ​​hole 131a into the receiving groove 14 to abut against the first inner surface 341 of the corner, thereby increasing the anti-detachment effect of the corner protector 1.

[0144] The snap-fit ​​part 153a can be a semi-circular structure, and the diameter of the snap-fit ​​part 153a is the same as the width of the snap-fit ​​hole 131a, so that the snap-fit ​​part 153a can be inserted into the snap-fit ​​hole 131a and the two can be snapped together at the same time.

[0145] like Figure 9 The diagram shown is a schematic representation of the unfolded state of the corner protector 1 in a specific embodiment. The following text, in conjunction with... Figure 9 This section describes the specific steps involved in wrapping the corner protector 1 around the frame 3.

[0146] The corner protector 1 includes a lower protective plate 11, a first connecting panel 121, a second connecting panel 122, a first upper panel 131, a second upper panel 132, a first anti-detachment panel 151, a second anti-detachment panel 152, a snap-fit ​​part 153a, and a snap-fit ​​hole 131a. Each panel has a crease 16 between it, which can be a perforated fold line to facilitate bending along the crease 16 by the worker.

[0147] Specifically, the first connecting panel 121 and the second connecting panel 122 are respectively connected to two sides of the lower guard plate 11 that are approximately perpendicular to each other. Furthermore, there is a first crease 161 between the first connecting panel 121 and the lower guard plate 11, and a second crease 162 between the second connecting panel and the lower guard plate 11.

[0148] The first upper panel 131 is connected to the first connecting panel 121, and the second upper panel 132 is connected to the second connecting panel 122. Furthermore, there is a third crease 163 between the first upper panel 131 and the first connecting panel 121, and a fourth crease 164 between the second upper panel 132 and the second connecting panel 122.

[0149] The first anti-detachment panel 151 is connected to the side of the first upper panel 131 away from the first connecting panel 121, and the second anti-detachment panel 152 is connected to the side of the first anti-detachment panel 151 away from the first upper panel 131. Furthermore, there is a fifth crease 165 between the first anti-detachment panel 151 and the first upper panel 131, and a sixth crease 166 between the second anti-detachment panel 152 and the first anti-detachment panel 151.

[0150] The snap-fit ​​hole 131a can be a hole structure cut out from the first upper panel 131, and the snap-fit ​​part 153a can be two semi-circular structures connected to the second upper panel 132. A seventh crease 167 is provided between the snap-fit ​​part 153a and the second upper panel 132.

[0151] Please refer to the reference. Figure 4 and Figure 9 The steps for the corner protector 1 to cover the corner of the frame 3 are as follows: First, place the lower protector 11 below the frame 3 and attach it to the front side 31 of the corner. Bend the first connecting panel 121 upward along the first crease 161 and the second connecting panel 122 upward along the second crease 162, so that the first connecting panel 121 and the second connecting panel 122 are respectively attached to the two first outer sides 321 that are approximately perpendicular to each other in the corner.

[0152] Then, the first upper panel 131 is bent along the third crease 163, so that the first upper panel 131 is attached to the back side 33 of the corner. At the same time, the first anti-detachment panel 151 is bent downward along the fifth crease 165, and the second anti-detachment panel 152 is bent towards the first upper panel 131 along the sixth crease 166, so that the first anti-detachment panel 151 is folded to the inside of the first inner side 341, and the second anti-detachment panel 152 is folded to be attached to the surface of the photovoltaic module.

[0153] Then, the second upper panel 132 is bent along the fourth crease 164 so that the second upper panel 132 fits against the back side 33 of the corner, and part of the structure of the second upper panel 132 overlaps with part of the structure of the first upper panel 131.

[0154] Finally, the snap-fit ​​part 153a is bent into the snap-fit ​​hole 131a to achieve the connection and fixation of the corner protector 1.
