[0037] See Figure 1 , Figure 1 A structural schematic diagram of a photovoltaic module corner protector 100 in an embodiment of the present application is shown. The photovoltaic module corner protector 100 provided in an embodiment of the present application includes a buffer 1 and a reinforcement 2. The buffer 1 is provided with a slot, and the corner of the photovoltaic module 200 can be inserted into the slot; the reinforcement 2 is provided on the outside of the buffer 1, and the reinforcement 2 is constructed to be elastic and can squeeze the buffer 1 into the slot so that the buffer 1 clamps the photovoltaic module 200.
[0038] The photovoltaic module corner protector 100 proposed in the embodiments of the present application utilizes a buffer member 1, which is provided with a slot for inserting the corner of a photovoltaic module 200. The buffer member 1 can be inserted into the corner of the photovoltaic module 200 to provide protection for the corner. A reinforcement member 2 is provided on the outside of the buffer member 1 to press the buffer member 1 into the slot, thereby clamping the buffer member 1 against the photovoltaic module 200 and preventing it from falling off. This ensures that the photovoltaic module corner protector 100 provides continuous and stable protection for the photovoltaic module 200. Furthermore, the reinforcement member 2 is provided on the outside of the buffer member 1 to provide protection for the buffer member 1, thereby preventing damage to the buffer member 1.
[0039] In one embodiment, the buffer member 1 is constructed as a foam buffer member. The foam buffer member 1 is thick, lightweight, and has a certain compressive strength and compression deformation capacity. It can effectively separate adjacent photovoltaic modules 200 during packaging and transportation, preventing adjacent photovoltaic modules 200 from being damaged due to collision or friction.
[0040] In one embodiment, the reinforcement member 2 is constructed as a rubber or silicone reinforcement member. The rubber or silicone reinforcement member 2 has excellent elasticity. When placed outside the buffer member 1, it applies pressure to the buffer member 1 toward the interior of the slot, thereby tightening the buffer member 1 to the photovoltaic module 200 and ensuring that the photovoltaic module corner protector 100 is securely installed on the photovoltaic module 200. Furthermore, the rubber or silicone reinforcement member 2 has excellent wear resistance and structural strength, making it difficult to damage, thereby providing excellent protection for the buffer member 1.
[0041] See Figure 2 , Figure 2 The following diagram illustrates the structure of a reinforcement member 2 in one embodiment of the present application. To facilitate assembly of the reinforcement member 2 with the buffer member 1, a mounting groove 21 is provided on the reinforcement member 2, into which the buffer member 1 fits. Optionally, the mounting groove 21 is slightly smaller than the size of the buffer member 1 into which it fits. The reinforcement member 2 has a certain degree of elasticity, allowing it to expand through deformation. Therefore, even with a slightly smaller mounting groove 21, it can fit over the buffer member 1, providing a better grip for the buffer member 1.
[0042] In one embodiment, the reinforcement member 2 and the buffer member 1 are configured as separate structures. When installing the photovoltaic module corner protector 100 on the photovoltaic module 200, the buffer member 1 can be first assembled to the corners of the photovoltaic module 200. In this case, the buffer member 1 is not subject to the tightening force of the reinforcement member 2, which reduces the effort required when assembling the photovoltaic module 200. Afterwards, the reinforcement member 2 is placed over the outside of the buffer member 1 to tighten the buffer member 1 and prevent it from falling off the photovoltaic module 200.
[0043] Optionally, see Figure 3The photovoltaic module 200 is generally a rectangular structure with four corners, each of which is covered with a photovoltaic module corner protector 100. When multiple photovoltaic modules 200 are stacked, adjacent photovoltaic modules 200 are in contact with each other through the corner protectors, forming an effective protection and restraint, and helping the photovoltaic modules 200 to be stacked more stably and less likely to fall over.
[0044] In one embodiment, combining Figure 3 and Figure 4 As shown, the photovoltaic assembly 200 includes a photovoltaic panel 220 , which is provided with a long side and a short side. For a photovoltaic assembly 200 with a frame 210 on both the long side and the short side or without a frame 210 , the thickness of the long side and the short side are consistent.
[0045] Combine Figure 1 、 Figure 5 and Figure 6 As shown, to match the shape of the corner of photovoltaic module 200, buffer member 1 includes a first side 11 and a second side 12 arranged at an angle. A first slot 111 is provided on first side 11, and a second slot 121 is provided on second side 12. The width W1 of first slot 111 and the width W2 of second slot 121 are the same. First slot 111 and second slot 121 form the aforementioned slots, which together accommodate the corner of photovoltaic module 200. Two adjacent sides of photovoltaic module 200 are inserted into first slot 111 and second slot 121, respectively. By setting first slot 111 and second slot 121 to have the same width, they can respectively adapt to the long and short sides of photovoltaic module 200.
[0046] Photovoltaic modules 200 without a frame 210 have the advantages of a large light-receiving area and a high power generation rate. However, due to the lack of frame protection, protection during transportation has always been a pain point in the industry. The photovoltaic module corner protector 100 provided in the embodiment of the present application, by providing a foam cushioning member 1, can flexibly adjust its thickness to improve protection. It can especially provide effective protection for photovoltaic modules 200 without a frame 210, which is conducive to promoting the widespread application of photovoltaic modules 200 without a frame.
[0047] In another embodiment, combined Figure 3 、 Figure 7-Figure 9 As shown, the photovoltaic module 200 is provided with a frame 210 only on one of the short side or the long side, resulting in inconsistent thickness between the long and short sides. To address this issue, the width W1 of the first slot 111 is set to be different from the width W2 of the second slot 121. During assembly, the first slot 111 is secured to the frame 210, while the second slot 121 is secured to the photovoltaic panel 220.
[0048] Specifically, the angle between the first side 11 and the second side 12 is set to 90°, and the first slot 111 and the second slot 121 form an L-shaped slot to accommodate the rectangular photovoltaic module 200. It should be noted that the shape of the photovoltaic module corner protector 100 and the shape of the slot can be specifically set according to the structure of the photovoltaic module 200 to be protected, and can ensure that after the photovoltaic module corner protector 100 is embedded in the photovoltaic module 200, the inner wall of the slot is in contact with the photovoltaic module 200, and the photovoltaic module corner protector 100 is securely installed.
[0049] In one embodiment, please refer back to Figure 1 When the reinforcement member 2 is sleeved on the outside of the buffer member 1, the end of the reinforcement member 2 is flush with the end of the buffer member 1, so that the photovoltaic module corner guard 100 composed of the reinforcement member 2 and the buffer member 1 has a more regular shape.
[0050] In one embodiment, in order to further improve the firmness of the connection between the buffer 1 and the photovoltaic module 200, a plurality of protrusions 13 are provided on the inner wall of the slot, and the plurality of protrusions 13 abut against the front and / or back of the photovoltaic module 200. Figure 1 As shown, a plurality of protrusions 13 are provided on the inner walls of the first slot 111 and the second slot 121 .
[0051] By providing a plurality of protrusions 13 on the inner wall of the slot, a discrete pressing force is provided to the photovoltaic module 200, which helps prevent the buffer 1 from separating from the photovoltaic module 200. Moreover, compared with a solution in which the inner wall of the slot contacts the photovoltaic module 200, the discrete protrusions 13 exert less frictional resistance on the photovoltaic module 200, making it easier to insert the photovoltaic module 200 into the slot.
[0052] Alternatively, as Figure 1 As shown, a plurality of protrusions 13 are arranged in pairs, and the paired protrusions 13 are respectively arranged on two opposing inner walls of the slot, and the arrangement direction of the pair of protrusions 13 is perpendicular to the front or back of the photovoltaic module 200. The pair of protrusions 13 are arranged opposite each other, respectively abutting the front and back of the photovoltaic module 200, forming a clamping force on the photovoltaic module 200, which is more conducive to preventing the photovoltaic module 200 from falling out of the slot.
[0053] Alternatively, as Figure 1 As shown, at least one side surface of the protrusion 13 is flush with the slot opening of the card slot, that is, the slot opening of the card slot is provided with a protrusion 13. By providing the protrusion 13 at the slot opening, it is beneficial for the protrusion 13 to play the best anti-separation effect.
[0054] Specifically, if Figure 1As shown, four protrusions 13 are respectively provided at the notches of the first and second slots 111, 121. The protrusions 13 in the first and second slots 111, 121 are arranged in a substantially identical manner. Taking the first slot 111 as an example, two protrusions 13 are each provided on the upper and lower inner walls of the first slot 111, and the protrusions 13 on the upper and lower inner walls are arranged directly opposite the photovoltaic module 200.
[0055] In one embodiment, the protrusion 13 at the notch of the slot is set to a square structure. Compared with the circular convex structure, the protrusion 13 with the square structure has a larger contact area with the photovoltaic component 200, thereby providing better support and anti-slip effect.
[0056] In some other embodiments, a protrusion 13 is further provided at the junction of the first card slot 111 and the second card slot 121 . Here, the protrusion 13 is configured to be L-shaped, matching the shape of the corner of the card slot.
[0057] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.
[0058] The above-described embodiments merely represent several implementation methods of the present application. 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 a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
