Description

Technical Field

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

[0002] Photovoltaic modules are the core components of solar cells. A photovoltaic module typically includes a backsheet, cell strings, a glass panel, and a frame. The backsheet, cell strings, and glass panel are stacked to form a laminate, and the frame surrounds the edge of the laminate. The frame typically includes a long frame that surrounds the long side of the laminate and a short frame that surrounds the short side of the laminate. The long frame and the short frame are connected perpendicularly, forming a right-angled apex at the connection point.

[0003] During the transportation of photovoltaic modules, paper corner protectors are often used to protect the top corners of the frame to prevent friction and collisions. However, currently, paper corner protectors of different sizes need to be designed separately for different sizes of photovoltaic module frames, which increases the cost of paper corner protectors. Utility Model Content

[0004] Therefore, it is necessary to provide a photovoltaic module corner protector to address the issue of how to improve the versatility of corner protectors.

[0005] This application provides a photovoltaic module corner protector, including:

[0006] The corner protector body includes a base plate, a first side plate, and a second side plate. The first side plate and the second side plate are both disposed on the base plate and intersect with each other. The base plate, the first side plate, and the second side plate together form a receiving groove, which is used to receive the top corner of the frame.

[0007] A first positioning block is movably disposed on the base plate and opposite to the first side plate. The first positioning block can move in a direction that is close to or away from the first side plate.

[0008] The second positioning block is movably disposed on the base plate and opposite to the second side plate. The second positioning block can move in a direction close to or away from the second side plate.

[0009] The technical solution will be further explained below:

[0010] In one embodiment, a first adjustment groove is provided on the base plate, the first adjustment groove extends in a direction away from the first side plate, and the first positioning block is movably disposed in the first adjustment groove;

[0011] The base plate is provided with a second adjustment groove, which extends away from the second side plate, and the second positioning block is movably disposed in the second adjustment groove.

[0012] In one embodiment, the distance between the first positioning block and the first side plate ranges from 5mm to 50mm; the distance between the second positioning block and the second side plate ranges from 5mm to 50mm.

[0013] In one embodiment, the first positioning block has a first inclined surface facing the first side plate, and the first inclined surface is inclined away from the first side plate along the height direction in which the first positioning block protrudes from the bottom plate.

[0014] The second positioning block has a second inclined surface facing the second side plate, and along the height direction of the second positioning block protruding from the bottom plate, the second inclined surface is inclined away from the second side plate.

[0015] In one embodiment, a first elastic latch is provided on the side of the first positioning block near the first side plate, and the first elastic latch protrudes from the first positioning block in the direction of approaching the first side plate.

[0016] The second positioning block is provided with a second elastic latch on the side near the second side plate, and the second elastic latch protrudes from the second positioning block in the direction of approaching the second side plate.

[0017] In one embodiment, the surface of the first elastic latch is covered with a first anti-slip layer; the surface of the second elastic latch is covered with a second anti-slip layer.

[0018] In one embodiment, a first magnetic element is provided on the side of the first side plate facing the first positioning block, and the first magnetic element is used to adsorb the frame of the photovoltaic module.

[0019] The second side plate is provided with a second magnetic element on the side facing the second positioning block. The second magnetic element is used to adsorb the frame of the photovoltaic module.

[0020] In one embodiment, the base plate has a through-hole for positioning.

[0021] In one embodiment, the corner protector body is a corrugated paper folding structure.

[0022] In one embodiment, the corrugated paper includes a first surface layer, a second surface layer, and an interlayer located between the first surface layer and the second surface layer, the interlayer forming a honeycomb-shaped buffer cavity.

[0023] The aforementioned photovoltaic module corner protector is constructed by setting intersecting first and second side plates on the base plate, and by setting movable first and second positioning blocks on the base plate, with the first positioning block facing the first side plate and the second positioning block facing the second side plate. Thus, when the photovoltaic module corner protector is used to cover the top corner of the photovoltaic module frame, the base plate abuts against the bottom surface (C surface) of the frame, the first side plate abuts against the outer surface (B surface) of the long frame of the frame, and the first positioning block abuts against the inner surface (D surface) of the long frame; the second side plate abuts against the outer surface (B surface) of the short frame of the frame, and the second positioning block abuts against the inner surface (D surface) of the short frame of the frame. This allows the photovoltaic module corner protector to be fixedly covered onto the top corner of the frame to protect the top corner of the frame. Since the first positioning block can move towards or away from the first side panel, its position can be flexibly adjusted according to the width of the long frame, ensuring that the distance between the first positioning block and the first side can accommodate frames of different sizes. Similarly, since the second positioning block can move towards or away from the second side panel, its position can be flexibly adjusted according to the width of the short frame, ensuring that the distance between the second positioning block and the first side can accommodate frames of different sizes, thereby improving the versatility of photovoltaic module corner protectors.

[0033] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0037] One embodiment of this application provides a photovoltaic module corner protector for covering the top corner of the photovoltaic module's frame, thereby protecting the frame of the photovoltaic module. See also: Figure 1 as well as Figure 2 Specifically, one embodiment of the photovoltaic module corner protector includes a corner protector body, a first positioning block 21, and a second positioning block 22. The corner protector body includes a base plate 11, a first side plate 12, and a second side plate 13. Both the first side plate 12 and the second side plate 13 are disposed on the base plate 11 and intersect with each other. The base plate 11, the first side plate 12, and the second side plate 13 together form a receiving groove for accommodating the top corner of the frame. The first positioning block 21 is movably disposed on the base plate 11 and opposite to the first side plate 12, and can move towards or away from the first side plate 12. The second positioning block 22 is movably disposed on the base plate 11 and opposite to the second side plate 13, and can move towards or away from the second side plate 13.

[0038] Specifically, the aforementioned photovoltaic module corner protector is constructed by setting an intersecting first side plate 12 and a second side plate 13 on the base plate 11, and by setting a movable first positioning block 21 and a second positioning block 22 on the base plate 11, with the first positioning block 21 facing the first side plate 12 and the second positioning block 22 facing the second side plate 13. Thus, when the photovoltaic module corner protector is used to cover the top corner of the frame of the photovoltaic module, the base plate 11 abuts against the bottom surface (C surface) of the frame, the first side plate 12 abuts against the outer side surface (B surface) of the long frame of the frame, and the first positioning block 21 abuts against the inner side surface (D surface) of the long frame; the second side plate 13 abuts against the outer side surface (B surface) of the short frame of the frame, and the second positioning block 22 abuts against the inner side surface (D surface) of the short frame. This allows the photovoltaic module corner protector to be fixedly wrapped around the top corner of the frame to protect the top corner of the frame.

[0039] Furthermore, since the first positioning block 21 can move along the direction of approaching or moving away from the first side plate 12, the position of the first positioning block 21 can be flexibly adjusted according to the width of the long frame, ensuring that the distance between the first positioning block 21 and the first side can be adapted to different sizes of frames. Similarly, since the second positioning block 22 can move along the direction of approaching or moving away from the second side plate 13, the position of the second positioning block 22 can be flexibly adjusted according to the width of the short frame, ensuring that the distance between the second positioning block 22 and the first side can be adapted to different sizes of frames, thereby improving the versatility of the photovoltaic module corner protectors.

[0040] See Figure 1 The base plate 11 is provided with a first adjustment groove 111, which extends in a direction away from the first side plate 12. The first positioning block 21 is movably disposed in the first adjustment groove 111. Thus, by moving the first positioning block 21 along the first adjustment groove 111, the distance between the first positioning block 21 and the first side plate 12 can be adjusted to accommodate frame widths of different widths, thereby improving the stability of the position adjustment of the first positioning block 21.

[0041] Similarly, a second adjustment groove 112 is provided on the base plate 11, extending away from the second side plate 13. The second positioning block 22 is movably disposed in the second adjustment groove 112. Thus, by moving the second positioning block 22 along the second adjustment groove 112, the distance between the second positioning block 22 and the second side plate 13 can be adjusted to accommodate frame widths of different widths, thereby improving the stability of the position adjustment of the second positioning block 22.

[0042] Optionally, the distance between the first positioning block 21 and the first side plate 12 is 5mm-50mm, that is, the first positioning block 21 can move within a range of 125mm-50mm from the first side plate, thereby adapting to a frame with a width of 5mm-50mm, further improving the applicability of the photovoltaic module corner protector.

[0043] Similarly, the distance between the second positioning block 22 and the second side plate 13 is 5mm-50mm, meaning that the second positioning block 22 can move within a range of 135mm-50mm from the second side plate, thereby adapting to a frame with a width of 5mm-50mm and further improving the applicability of the photovoltaic module corner protector.

[0044] Optionally, in one embodiment, the first positioning block 21 has a first inclined surface (not shown) facing the first side plate 12. Along the height direction of the first positioning block 21 protruding from the base plate 11, the first inclined surface is inclined away from the first side plate 12. In this way, when the top corner of the frame is put into the receiving groove from top to bottom, the long frame can slide along the first inclined surface into the space between the first side plate 12 and the first positioning block 21, which facilitates the installation of the photovoltaic module corner protector.

[0045] Similarly, the second positioning block 22 has a second inclined surface (not shown) facing the second side plate 13. Along the height direction of the second positioning block 22 protruding from the base plate 11, the second inclined surface is inclined away from the second side plate 13. In this way, when the top corner of the frame is put into the receiving groove from top to bottom, the short frame can slide along the second inclined surface into the space between the second side plate 13 and the second positioning block 22, which facilitates the installation of the photovoltaic module corner protector.

[0046] See Figure 1 Optionally, in one embodiment, a first elastic latch 211 is provided on the side of the first positioning block 21 near the first side plate 12, and the first elastic latch 211 protrudes from the first positioning block 21 in the direction close to the first side plate 12. Specifically, the first elastic latch 211 is used to engage with the D-side of the long frame, thereby improving the installation and fixing effect of the photovoltaic module corner protector and preventing the photovoltaic module corner protector from falling off the frame. Further, the surface of the first elastic latch 211 is covered with a first anti-slip layer, which can improve the engagement stability between the first elastic latch 211 and the D-side of the long frame, and further improve the installation stability of the photovoltaic module corner protector. Exemplarily, the first anti-slip layer can be a silicone anti-slip layer. Understandably, the first elastic latch 211 can elastically deform, thus ensuring that the top corner of the frame can be inserted into or removed from the receiving groove.

[0047] Similarly, a second elastic latch 221 is provided on the side of the second positioning block 22 near the second side plate 13. The second elastic latch 221 protrudes from the second positioning block 22 in the direction close to the second side plate 13. The second elastic latch 221 is used to engage with the D-side of the short frame, thereby improving the fixing effect of the photovoltaic module corner protector and preventing the photovoltaic module corner protector from falling off the frame. Furthermore, the surface of the second elastic latch 221 is covered with a second anti-slip layer, which can improve the engagement effect between the second elastic latch 221 and the D-side of the short frame, further improving the installation stability of the photovoltaic module corner protector. For example, the second anti-slip layer can be a silicone anti-slip layer. Understandably, the second elastic latch 221 can be elastically deformed, thus ensuring that the top corner of the frame can be inserted into or removed from the receiving groove.

[0048] See Figure 1 In one embodiment, a first magnetic element 31 is provided on the side of the first side plate 12 facing the first positioning block 21. The first magnetic element 31 is used to adsorb the frame of the photovoltaic module. Specifically, the frame is usually made of metal. By providing the first magnetic element 31 on the first side plate 12, after the top corner of the photovoltaic module is placed into the receiving groove, the first magnetic element 31 can be adsorbed onto the long edge of the frame, thereby fixing the corner protector of the photovoltaic module to the frame and preventing the corner protector of the photovoltaic module from falling off.

[0049] Similarly, a second magnetic component is provided on the side of the second side plate 13 facing the second positioning block 22. The second magnetic component is used to attach to the short frame of the frame, thereby also fixing the photovoltaic module corner protector to the frame and preventing the photovoltaic module corner protector from falling off.

[0050] See Figure 1 In one embodiment, the base plate 11 has a through-hole 113 for positioning. Specifically, the positioning hole 113 is used to cooperate with a positioning pin on an automated installation device, thereby positioning the photovoltaic module corner protectors on the automated installation device, facilitating automated installation and improving production efficiency. Preferably, the base plate 11 has at least two positioning holes 113, thereby improving positioning accuracy.

[0051] Optionally, in one embodiment, the corner protector body is a corrugated cardboard folded structure. Corrugated cardboard is lightweight and has a certain cushioning effect, which can ensure the protection of the frame at a relatively low cost.

[0052] Furthermore, the corrugated paper includes a first surface layer, a second surface layer, and an interlayer located between the first surface layer and the second surface layer, the interlayer forming a honeycomb-shaped buffer cavity. By setting the honeycomb-shaped buffer cavity within the interlayer, the buffering effect of the photovoltaic module corner protectors on the frame can be further improved, thereby enhancing the protection effect on the frame.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
