Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, specifically to a high-strength dust-proof photovoltaic module frame. Background Technology

[0002] With the widespread application of photovoltaic technology, photovoltaic modules face numerous challenges during outdoor power generation, among which dust accumulation is particularly prominent. Wind, sand, and rain can cause dust to accumulate on the surface of photovoltaic modules, severely impacting their power generation efficiency. To address this issue, various dust-prevention solutions have been proposed in existing technologies. For example, utility model patent CN221240271U proposes a module without an A-side frame, and utility model patent CN217721115U proposes a module without an A-side frame.

[0003] However, these existing technologies still have many shortcomings in practical applications. For example, the first solution only achieves the A-side-less design on the short side, which limits the installation methods of the modules and cannot meet the dust prevention requirements of horizontally installed modules; although the second solution achieves dust prevention on both the long and short sides, the load on the back of the module is prone to detachment during IEC standard load testing, posing a safety hazard. In addition, existing dustproof modules also have the problem of adhesive overflow on the front of the module during the framing process, which not only increases the difficulty of framing but also increases the difficulty of cleaning the modules.

[0004] Therefore, while existing technologies solve the problem of dust accumulation in photovoltaic modules, they fail to take into account the convenience of module mounting, sealing, and stability during load testing. There is an urgent need for a new photovoltaic module frame design that can comprehensively solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength, dust-resistant photovoltaic module frame to solve the aforementioned problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following solution: a high-strength dust-proof photovoltaic module frame, comprising a frame body and fasteners, wherein multiple fasteners are installed at intervals along the edge of the frame body; the frame body is bonded to the lower surface edge of the laminate, one side of the fastener is attached to the upper surface of the laminate, and the other side is threadedly connected to the frame body; the frame body is formed by a frame C side, a frame D side, a frame B side, and a frame A side, and has an internal cavity; a module fixing boss one and a module fixing boss two are connected above the frame A side, the module fixing boss one and the module fixing boss two support the laminate from different positions, and a bottom adhesive groove is formed between the module fixing boss one and the module fixing boss two for accommodating sealant.

[0007] As an optional implementation, the upper surface of the first component fixing boss is higher than the second component fixing boss, so that when the laminate is installed, the gap between the second component fixing boss and the laminate is filled with sealant.

[0008] As an optional implementation, a side adhesive groove is formed between the frame B side and the component fixing boss.

[0009] As an optional implementation, the frame body has several threaded holes on one side of the frame B that are threaded to the fastener.

[0010] As an optional implementation, the fastener includes a vertical mounting part and a horizontal pressing part, the vertical mounting part and the horizontal pressing part forming a 90° angle, and the vertical mounting part is provided with a mounting hole that mates with the threaded hole.

[0011] As an optional implementation, the lower section of the B-side of the frame protrudes outward, and the upper section forms an L-shaped indentation, which is used to accommodate the vertical mounting part of the fastener.

[0012] As an optional implementation, the bottom end of the vertical mounting part is connected to a support surface that is parallel to the horizontal pressing part and has the same bending direction. The width of the support surface is the same as the C-side of the frame body.

[0013] As an optional implementation, the inner corners of the vertical mounting part and the horizontal pressing part are provided with protruding ridges, and when the fastener is assembled with the frame body, the protruding ridges abut against the top of the B side of the frame.

[0014] As an optional implementation, the fastener is integrally formed.

[0015] As an optional implementation, the frame body is integrally formed.

[0016] Compared with the prior art, the present invention discloses at least the following beneficial effects:

[0017] This invention proposes a high-strength, dust-resistant photovoltaic module frame. Through optimized frame structure design, it comprehensively solves the problems of dust accumulation, adhesive overflow, and insufficient load stability in existing photovoltaic module frames. The coordinated design of the frame body and the fixing components effectively prevents dust accumulation on the photovoltaic module surface, improving power generation efficiency. The side and bottom adhesive grooves prevent sealant overflow, simplifying the frame assembly process and reducing cleaning difficulty. The optimized structure of the fixing components enhances the module's installation strength and load stability, eliminating the safety hazard of modules easily detaching during load testing in existing technologies. Simultaneously, the integrated molding design of the frame body and fixing components improves the overall structural reliability without affecting the A-side-less design of the frame, balancing dust prevention with module installation flexibility.

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Existing framed photovoltaic modules have the following drawbacks:

[0036] 1. Dust accumulation on photovoltaic module surface: When photovoltaic modules are operating outdoors, dust easily accumulates on their surface due to wind, sand, and rain, thus reducing power generation efficiency. Existing dust accumulation prevention solutions have limitations and cannot effectively solve this problem.

[0037] 2. Excessive sealant during the framing process of existing dustproof components: During the framing process, the sealant of existing dustproof components tends to overflow from the front of the components, which not only increases the difficulty of framing but also increases the difficulty of cleaning the components, and limits the installation methods of the components.

[0038] 3. Problem of existing dustproof components easily falling off during load testing: When conducting IEC standard load tests, existing dustproof components are prone to falling off from inside the frame when subjected to back load, causing the components to explode and posing a safety hazard.

[0039] In view of the above-mentioned technical problems, this application aims to solve the above-mentioned problems in a comprehensive manner through a novel photovoltaic module frame design, thereby improving the anti-dust accumulation performance, frame mounting convenience, and load stability of photovoltaic modules.

[0040] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Example 1:

[0042] Reference Figures 1 to 7 As shown, Embodiment 1 of this utility model provides a high-strength dust-proof photovoltaic module frame, including a first frame body 10a and a plurality of first fasteners 20a that cooperate with the first frame body 10a.

[0043] like Figure 1 and Figure 4 As shown, the first frame body 10a is formed by frame C side 1, frame D side 2, frame B side 3, and frame A side 5, and has an internal cavity 4. The cavity 4 is used to install corner pieces (corner pieces are connectors connecting the long and short frames of the component). Frame B side 3 extends beyond the top of frame A side 5, and frame C side 1 extends inward beyond frame D side 2 by one end. Frame C side 1 provides support strength and provides mounting holes 13 for installation with the photovoltaic bracket. Frame C side 1 has the same structure as a conventional frame and will not be described in detail here. Frame B side 3 includes a B side body 33. The bottom of the B side body 33 protrudes outward to form a B side protrusion 31, and the top of the B side protrusion 31 forms a stepped surface 32. The B side body 33 forms an L-shaped inward recess relative to the B side protrusion 31 to accommodate the first fixing member 20a. The B side body 33 has several sets of threaded holes 34 spaced apart for installing the first fixing member 20a. The frame A side 5 serves as the support for the laminate 40, and is provided with component fixing boss 7 and component fixing boss 9 on its upper surface. The bottom end of component fixing boss 7 is fixed to the inner side of frame B side 3, and its top end extends upward and inward toward the inner side of frame A side 5, forming a horizontal support mounting part. The bottom end of component fixing boss 9 is connected to the inner edge of frame A side 5, that is, directly above frame D side 2, and its top end extends inward, forming a horizontal support mounting part. The component fixing boss 7 and component fixing boss 9 support the laminate 40 from different positions, and the groove between component fixing boss 7 and component fixing boss 9 forms a bottom adhesive receiving groove 8 for accommodating sealant 30, which connects the frame and the laminate 40.

[0044] In a further optimized design, the height of the component fixing boss 7 is higher than that of the component fixing boss 9, so that when the laminate 40 is installed, there is a gap between the component fixing boss 9 and the laminate 40. This gap can accommodate the overflow of sealant 30 and increase the contact surface between sealant 30 and laminate 40.

[0045] In a further optimized design, a side adhesive groove 6 is formed between the frame B side 3 and the component fixing boss 7. This groove is used to accommodate the sealant 30 overflowing from the edge of the laminate 40 during frame assembly, preventing adhesive overflow and preventing the frame from directly contacting the glass edge in the laminate 40, thus preventing the glass corners from being popped off.

[0046] In a further optimized design, the first frame body 10a in this embodiment is integrally formed and is preferably made of aluminum alloy.

[0047] like Figure 2 and Figure 5 As shown, the first fixing member 20a includes a vertical mounting part 11 and a horizontal pressing part 12, which are at a 90° angle and are integrally formed. The vertical mounting part 11 is provided with a mounting hole 13, which is fixedly connected to the threaded hole 34 on the B side 3 of the frame by bolts. The horizontal pressing part 12 is used to cooperate in pressing the laminate 40. Compared with the existing A-side-less frame assembly, the first fixing member 20a of this embodiment cooperates with the first frame body 10a to fix the laminate 40, which can provide the installation strength and load stability of the laminate 40. In addition, the first fixing member 20a is a small-sized component and does not affect the A-side-less design of the first frame body 10a. This solves the problem of dust accumulation on the surface of the photovoltaic module and avoids the safety hazard of the photovoltaic module easily detaching from the inside of the frame during load testing.

[0048] like Figure 3 As shown, the first frame body 10a of this embodiment is used in conjunction with the first fixing member 20a to fix the laminate 40. The laminate 40 is bonded to the first frame body 10a by the sealant 30. The component fixing boss 1 7 and the component fixing boss 2 9 play a supporting and fixing role. The first fixing member 20a forms a fixing from above the laminate 40.

[0049] like Figure 6 and Figure 7 As shown, multiple first fasteners 20a are spaced along the edge of the laminate 40. On the one hand, this improves the load strength of the component and effectively prevents the component from delaminating. On the other hand, the width of the shielding of the edge of the laminate 40 is limited, and it is not easy to form dust accumulation.

[0050] Example 2:

[0051] Reference Figure 8 and Figure 9As shown, Embodiment 2 of this utility model provides another high-strength anti-dust photovoltaic module frame, including a first frame body 10a and a plurality of second fixing members 20b that cooperate with the first frame body 10a. The structure of the first frame body 10a is the same as that of the first frame body 10a in Embodiment 1, and will not be described again here. The structure of the second fixing member 20b is different from that of the first fixing member 20a in Embodiment 1. Based on the first fixing member 20a, a protruding ridge 15 is added at the inner angle between the vertical mounting part 11 and the horizontal pressing part 12 of the second fixing member 20b.

[0052] In this embodiment, after the laminate 40 is assembled with the first frame body 10a, its height is higher than the top of the frame B side 3 of the first frame body 10a, further reducing the obstruction of the edge of the laminate 40 by the frame and making it less likely for dust to accumulate on the edge of the upper surface of the laminate 40. At this time, the upper surface of the laminate 40 is raised by a certain distance relative to the upper end of the first frame body 10a. In order to accommodate the raised upper surface of the laminate 40, a protruding ridge 15 is provided at the inner corner of the second fixing member 20b. During installation, the protruding ridge 15 abuts against the top of the first frame body 10a, which improves the assembly connection strength on the one hand and reduces the pressure on the upper surface of the laminate 40 on the other hand, thereby reducing the stress on the upper surface of the laminate 40 and preventing the laminate 40 from bursting.

[0053] Example 3:

[0054] Reference Figures 10 to 12 As shown, Embodiment 3 of this utility model provides another high-strength dust-proof photovoltaic module frame, including a second frame body 10b and a plurality of third fasteners 20c that cooperate with the second frame body 10b.

[0055] like Figure 10 As shown, the structure of the second frame body 10b is basically the same as that of the first frame body 10a in Embodiment 1. It is formed by the enclosure of frame C side 1, frame D side 2, frame B side 3, and frame A side 5, and has an internal cavity 4. Frame B side 3 extends beyond the top of frame A side 5, and frame C side 1 extends inward beyond frame D side 2 by one length. The difference is that frame B side 3 is a flat vertical surface and does not have a B side protrusion 31. The structure of other positions is the same as that of the first frame body 10a, and will not be described in detail here.

[0056] like Figure 11 As shown, the third fastener 20c adds a support surface 14 at the bottom of the vertical mounting part 11 on the basis of the first fastener 20a. The support surface 14 is parallel to the horizontal pressing part 12, and its width is consistent with the width of the side C of the second frame body 10b.

[0057] like Figure 12As shown, when the third fastener 20c is assembled, its horizontal pressing part 12 is in close contact with the upper surface of the laminate 40, the inner side of the vertical mounting part 11 is in close contact with the outer side of the frame B side 3, and the support surface 14 is in close contact with the lower surface of the frame C side 1, thus clamping and fixing the second frame body 10b and the laminate 40 inside it to form a stable support.

[0058] Example 4:

[0059] Reference Figure 13 and Figure 14 As shown, Embodiment 4 of this utility model provides another high-strength dust-proof photovoltaic module frame, including a second frame body 10b and a plurality of fourth fasteners 20d that cooperate with the second frame body 10b.

[0060] The second border body 10b has the same structure as the second border body 10b in Embodiment 3, and will not be described in detail here.

[0061] The main structure of the fourth fastener 20d is the same as that of the third fastener 20c. The difference is that a protruding ridge 15, the same as that of the second fastener 20b, is provided at the inner corner between the vertical mounting part 11 and the horizontal pressing part 12. The purpose of the protruding ridge 15 is the same as that of the second fastener 20b in embodiment 2, and will not be described in detail here.

[0062] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0063] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
