[0056] Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0057] As Figure 1 shown, the present invention provides a corner protector for a photovoltaic module. The corner protector of the photovoltaic module includes: a first side plate 10 and a second side plate 20; one end of the first side plate 10 is connected to one end of the second side plate 20 to form an L-shaped structure, and the extending direction x of the long side of the first side plate 10 is perpendicular to the extending direction y of the long side of the second side plate; the L-shaped structure is used to cover a corner of the photovoltaic module (not shown in the figure); a positioning bump 30 is provided on the first long side surface 11 of the first side plate 10 and / or the second long side surface 21 of the second side plate 20; the first long side surface 11 and the second long side surface 21 are the sides parallel to the horizontal plane when the corner protector is placed horizontally; further referring to Figure 2 , a positioning groove 31 is provided at a position overlapping with the positioning bump 30 in the third long side surface 12 of the first side plate 10 and / or the fourth long side surface 22 of the second side plate 20; the third long side surface 12 is the side opposite to the first long side surface 11; the fourth long side surface 22 is the side opposite to the second long side surface 21; the end of the positioning bump 30 is a chamfered structure.

[0058] A photovoltaic module is a module formed by electrically connecting multiple solar cells. In the storage and transportation of photovoltaic modules, multiple photovoltaic modules can be stacked to achieve batch storage and transportation, thereby improving efficiency. However, during this process, the corners of the photovoltaic modules are easily bumped and scratched, which affects the finished product quality of the photovoltaic modules. Therefore, it is necessary to effectively protect the corners of the photovoltaic modules.

[0059] In the embodiment of the present utility model, corner protectors as shown in Figure 1 can be provided at the four corners of each photovoltaic module, so as to achieve the protection of the corners of the photovoltaic module that are most easily bumped. First, the corner protector includes a first side plate 10 and a second side plate 20. The first side plate 10 and the second side plate 20 form an L-shaped structure. When the corner protector is provided at the corner of the photovoltaic module, the first side 10 can contact one side of the corner position of the photovoltaic module and play a role in protecting one side of the photovoltaic module in the x direction; the second side 20 can contact the adjacent other side of the corner position of the photovoltaic module and play a role in protecting the other side of the photovoltaic module in the y direction. The manufacturing process of the corner protector can be injection molding by die opening. In this way, the produced corner protector has high product size accuracy and strong matching. In addition, the material of the corner protector can use recyclable polypropylene (PP, polypropylene) material.

[0060] Furthermore, in the embodiment of the present utility model, positioning protrusions 30 can be provided on the first long side surface 11 of the first side plate 10 and the second long side surface 21 of the second side plate 20, and positioning grooves 31 can be provided at positions overlapping with the positioning protrusions 30 on the third long side surface 12 of the first side plate 10 and the fourth long side surface 22 of the second side plate 20. Referring to Figure 3 , in this way, when multiple photovoltaic modules are stacked, the corner protector of the corner of one photovoltaic module can be inserted and fixed with the corner protector of the same corner of the adjacent another photovoltaic module by inserting the positioning protrusion 30 into the corresponding positioning groove 31, thereby realizing the mutual connection and fixation between the upper and lower layers of photovoltaic modules, avoiding the mutual sliding between different layers when the photovoltaic modules are stacked, improving the stability of the stacked photovoltaic modules, and reducing the probability of the photovoltaic modules being damaged due to sliding and tipping.

[0061] It should be noted that in the embodiment of the present utility model, the positioning protrusion 30 can also be provided only on the first long side surface 11 of the first side plate 10, and the positioning groove 31 can be provided at the position overlapping with the positioning protrusion 30 on the third long side surface 12 of the first side plate 10; or the positioning protrusion 30 can be provided only on the second long side surface 21 of the second side plate 20, and the positioning groove 31 can be provided at the position overlapping with the positioning protrusion 30 on the fourth long side surface 22 of the second side plate 20. This can also meet the purpose of mutual insertion and fixation of the corner protectors of any two layers when the photovoltaic modules are stacked.

[0062] In addition, the end of the positioning bump 30 can be a chamfered structure. When the positioning bump 30 is inserted into the corresponding positioning groove 31, the chamfered structure can play a role in guiding the insertion, making the insertion operation easier and reducing the operation difficulty.

[0063] In summary, in the embodiment of the present utility model, the corner guard includes: a first side plate and a second side plate; one end of the first side plate is connected to one end of the second side plate to form an L-shaped structure for covering the corner of the photovoltaic module. Positioning bumps are provided on the first long side surface of the first side plate and / or the second long side surface of the second side plate; positioning grooves are provided at positions overlapping with the positioning bumps on the third long side surface of the first side plate and / or the fourth long side surface of the second side plate; the end of the positioning bump is a chamfered structure. When multiple photovoltaic modules are stacked, the corner guard of the corner of one photovoltaic module can be inserted and fixed to the corner guard of the same corner of an adjacent photovoltaic module by inserting the positioning bump into the corresponding positioning groove, thereby avoiding the mutual slippage between different layers when the photovoltaic modules are stacked, improving the stability of the stacked photovoltaic modules, and reducing the probability of the photovoltaic modules being damaged due to tipping caused by slippage. In addition, the chamfered structure at the end of the positioning bump makes the insertion operation easier and reduces the operation difficulty.

[0064] Optionally, the positioning bump and the positioning groove are in interference fit. The interference fit between the positioning bump and the positioning groove can enable the structure after the positioning bump is inserted into the positioning groove to resist external interference and maintain

[0065] the tightness of the assembly.

[0066] Optionally, the positioning groove extends into the interior of the positioning bump.

[0067] In the embodiment of the present utility model, the interior of the positioning bump until the opening of the positioning groove can be a hollow structure. Such a design can effectively reduce the material consumption of the corner guard on the basis of meeting the functions of the corner guard, playing a role in cost saving.

[0068] Optionally, referring to Figure 1 , bolt positioning grooves 50 are provided on the first long side surface 11 and / or the second long side surface 21, and through holes 51 are provided on the side walls of the bolt positioning grooves 50; the positions of the bolt positioning grooves 50 and the through holes 51 do not interfere with the positions of the positioning bumps 30 and the positioning grooves 31; the extending directions of the bolt positioning grooves 50 and the through holes 51 are parallel to the short side extending direction z of the first side plate.

[0069] In the embodiment of the present utility model, bolt positioning grooves 50 can be provided on the first long side surface 11 and / or the second long side surface 21 ( Figure 1shows a case where a bolt positioning groove 50 is provided on the second long side surface 21), referring to Figure 3 , multiple stacked photovoltaic modules can be transported by a pallet 60. When multiple stacked photovoltaic modules are placed on the pallet 60, the corner guards in direct contact with the pallet 60 can use fixing bolts to insert through holes 51 in the bolt positioning grooves 50 of the corner guards and further insert into the pallet 60 to achieve the fixed connection between the bottom-layer photovoltaic module and the pallet 60, avoiding relative slippage between the stacked photovoltaic modules and the pallet 60. The remaining layers of photovoltaic modules are fixedly connected to each other by inserting positioning bumps into corresponding positioning grooves to avoid relative slippage.

[0070] It should be noted that when multiple stacked photovoltaic modules are placed on the pallet 60, according to actual needs, a certain number of photovoltaic modules can be taken from the top for transfer. The taken certain number of photovoltaic modules are still stacked and placed on a new transfer pallet. At this time, for the corner guard of the bottom-layer photovoltaic module among the taken certain number of photovoltaic modules, fixing bolts can be inserted into the through holes 51 in the bolt positioning grooves 50 of the corner guard and further inserted into the transfer pallet to achieve the fixed connection between the taken certain number of photovoltaic modules and the transfer pallet.

[0071] Optionally, referring to Figure 1 , arc-shaped grooves 41 are provided on the first surface of the first side plate 10 and / or the second surface of the second side plate 20; fixing columns 42 are fixedly arranged in the arc-shaped grooves 41, and the fixing columns 42 are used to tie a fixing band (not shown in the figure); when the corner guard covers a corner of the photovoltaic module, the first surface and the second surface are the surfaces facing away from the side of the photovoltaic module.

[0072] In the embodiment of the present invention, further referring to Figure 3 , the fixing columns 42 in the arc-shaped grooves 41 provided on the first surface of the first side 10 and the second surface of the second side plate 20 can be used to tie one end of the fixing band. In addition, multiple stacked photovoltaic modules can be transported by a pallet 60. When multiple stacked photovoltaic modules are placed on the pallet 60, the other end of the fixing band can be fixed on the bearing surface of the pallet 60, thereby further improving the fixing stability between the stacked photovoltaic modules and the pallet and avoiding relative slippage between the stacked photovoltaic modules and the pallet. Preferably, the other end of the fixing band can be fixed at the corresponding corner position of the pallet 60. For example, the other end of the fixing band of the corner guard at the lower right corner of the photovoltaic module is fixedly connected to the corner at the lower right corner of the pallet 60.

[0073] It should be noted that preferably, the arc-shaped grooves 41 and the fixing columns 42 can be provided only on the corner guards of the non-bottom-layer photovoltaic modules in the stacked photovoltaic modules ( Figure 1 and Figure 2on the corner protector), referring to Figure 4 , the arc-shaped groove and the fixing post may not be provided on the corner protector of the bottommost photovoltaic module.

[0074] Optionally, referring to Figure 1 , two positioning bumps 30 are respectively and spacedly provided on the first long-side surface 11 and the second long-side surface 21. The two positioning bumps 30 are respectively and spacedly provided on the first long-side surface 11 and the second long-side surface 21, so that the structure obtained after the upper and lower corner protectors are inserted into each other has stronger stability and more uniform force.

[0075] Optionally, referring to Figure 1 , a plurality of first guard plates 70 are spacedly provided on the first long-side surface 11 and the second long-side surface 21. The first guard plate 70 on the first long-side surface 11 is perpendicular to the first side plate 10; the first guard plate 70 on the second long-side surface 21 is perpendicular to the second side plate 20; the extension length h1 of the first guard plate 70 on the first long-side surface 11 is greater than the extension length h2 of the first guard plate 70 on the second long-side surface 21; when the corner protector wraps an edge corner of the photovoltaic module, the first guard plate extends in a direction close to the photovoltaic module.

[0076] In the embodiment of the present utility model, a photovoltaic frame is provided on the side of the photovoltaic module. In order to play the role of the corner protector in clamping and protecting the photovoltaic frame at the corner, a plurality of first guard plates 70 may be spacedly provided on the first long-side surface 11 and the second long-side surface 21. The first guard plate 70 can abut against the first surface (the surface parallel to the light-receiving surface of the photovoltaic module) of the photovoltaic frame at the corner, so as to play the role of positioning and protecting the first surface of the photovoltaic frame at the corner.

[0077] In addition, the photovoltaic frame has the characteristic that the width of the long-side frame is greater than the width of the short-side frame, and the first side plate of the corner protector contacts the long-side frame of the photovoltaic frame, and the second side plate of the corner protector contacts the short-side frame of the photovoltaic frame. Therefore, in order to meet the matching of the structure of the corner protector with the above characteristics of the photovoltaic frame, the extension length h1 of the first guard plate 70 on the first long-side surface 11 may be set to be greater than the extension length h2 of the first guard plate 70 on the second long-side surface 21. In this way, when the corner protector wraps the edge corner of the photovoltaic module, the extension length of the first guard plate can be adapted to the width of the photovoltaic frame it contacts, improving the protection effect of the corner protector.

[0078] Optionally, referring to Figure 1 and Figure 2, at least one second guard plate 71 is provided on the third long side surface 12 and the fourth long side surface 22; the position of the gap a formed between the second guard plate 71 and the adjacent first guard plate 70 overlaps; the second guard plate 71 on the third long side surface 12 is perpendicular to the first side plate 10; the second guard plate 71 on the fourth long side surface 22 is perpendicular to the second side plate 20; the extension length h3 of the second guard plate 71 on the third long side surface 12 is greater than the extension length h4 of the second guard plate 71 on the fourth long side surface 22; when the corner guard wraps an edge angle of the photovoltaic module, the second guard plate 71 extends towards the direction close to the photovoltaic module; when any two corner guards are stacked, referring to Figure 5 , the positioning convex block 30 of one corner guard is inserted into the positioning groove 31 of the other corner guard, and the second guard plate 71 of one corner guard is embedded into the gap a between the first guard plates 70 of the other corner guard, thereby forming a bearing surface for bearing the frame of the photovoltaic module.

[0079] In the embodiment of the present utility model, a photovoltaic frame is provided on the side of the photovoltaic module. In order to play the role of clamping and protecting the photovoltaic frame at the corner by the corner guard, at least one second guard plate 71 can be provided on the third long side surface 12 and the fourth long side surface 22. The second guard plate 71 can abut against the second surface (the surface opposite to the first surface of the photovoltaic frame) of the photovoltaic frame at the corner, so as to play the role of positioning and protecting the second surface of the photovoltaic frame at the corner. In addition, the extension length h3 of the second guard plate 71 on the third long side surface 12 is set to be greater than the extension length h4 of the second guard plate 71 on the fourth long side surface 22; in this way, when the corner guard wraps the corner of the photovoltaic module, the extension length of the second guard plate can be adapted to the width of the photovoltaic frame it contacts, improving the protection effect of the corner guard.

[0080] Furthermore, when any two corner guards are stacked, the positioning convex block 30 of one corner guard is inserted into the positioning groove 31 of the other corner guard, and the second guard plate 71 of one corner guard is embedded into the gap a between the first guard plates 70 of the other corner guard, thereby forming a bearing surface for bearing the second surface of the photovoltaic frame of the photovoltaic module, so that the second surface of the photovoltaic frame of the photovoltaic module can be stably placed on the bearing surface formed after the second guard plate 71 is embedded into the gap a, thereby improving the stability between the stacked photovoltaic modules.

[0081] Optionally, referring to Figure 4 and Figure 6 , a third guard plate 72 is provided on the third long side surface 12 and the fourth long side surface 22; the third guard plate 72 on the third long side surface 12 is perpendicular to the first side plate 10; the third guard plate 72 on the fourth long side surface 22 is perpendicular to the second side plate 20; when the corner guard wraps an edge angle of the photovoltaic module, the third guard plate 72 extends towards the direction close to the photovoltaic module; the extension length h5 of the third guard plate 72 on the third long side surface 12 is greater than the extension length h6 of the third guard plate 72 on the fourth long side surface 22.

[0082] In a preferred implementation of the embodiment of the present utility model, when multiple photovoltaic modules are stacked, Figure 1 and Figure 2 the corner guards shown can be the corner guards of the photovoltaic modules that are not the bottom layer, while Figure 4 and Figure 6 the corner guards shown can be the corner guards of the bottom layer photovoltaic modules.

[0083] In the embodiment of the present utility model, a photovoltaic frame is provided on the side of the photovoltaic module. In order to play the role of clamping and protecting the photovoltaic frame at the corner by the corner guard of the bottom layer, at least one third guard plate 72 can be provided on the third long side surface 12 and the fourth long side surface 22 of the corner guard of the bottom layer. The area of the third guard plate 72 of the corner guard of the bottom layer is larger than the area of the second guard plate 71 of the corner guard that is not the bottom layer. The larger area third guard plate 72 can directly abut against the second surface (the surface opposite to the first surface of the photovoltaic frame) of the photovoltaic frame at the corner, playing the role of positioning and protecting the second surface of the photovoltaic frame at the corner of the bottom layer photovoltaic module. In addition, the extension length h5 of the third guard plate 72 on the third long side surface 12 is set to be greater than the extension length h6 of the third guard plate 72 on the fourth long side surface 22. In this way, when the corner guard wraps around the corner of the photovoltaic module, the extension length of the third guard plate can be adapted to the width of the photovoltaic frame it contacts, improving the protection effect of the corner guard.

[0084] Optionally, referring to Figure 1 , Figure 2 , Figure 5 , on the first guard plate 70 and the second guard plate 71, clamping strips 90 for clamping with the frame of the photovoltaic module are respectively provided; a bearing plate 80 is also provided at the connection position of the third long side surface 12 and the fourth long side surface 22; the bearing plate 80 is perpendicular to the first side plate 10 and the second side plate 20.

[0086] In the embodiment of the present utility model, the photovoltaic frame of the photovoltaic module is slightly higher than the light-receiving / backlight surface of the photovoltaic module, thus forming a stepped structure. The clamping strip 90 is used to form a clamping effect on this stepped structure to improve the connection stability between the corner guard and the corner of the photovoltaic module. In addition, the bearing plate 80 further increases the bearing area of the corner guard on the photovoltaic module, making the bearing more stable.
