Abstract
Description
Technical Field
[0001] This application relates to the field of photovoltaic equipment technology, and in particular discloses a single-glass module frame reinforcement structure resistant to mechanical stress. Background Technology
[0002] In the field of photovoltaic power generation, single-glass modules are increasingly widely used due to their advantages such as lightweight and cost-effectiveness. However, compared with double-glass modules, single-glass modules are relatively weaker in terms of mechanical strength, especially in terms of resistance to bending, impact, and mechanical stress such as wind pressure and snow load. As a key support and protective structure, the performance of the module frame directly affects the overall reliability and service life of the module.
[0003] Currently, common single-glass module frames mainly include closed rectangular frame structures and open single C-shaped frame structures. In the closed rectangular frame structure, part of the frame adopts an integrated rectangular cross-section design. Although this structure has high overall strength, it lacks effective stress buffering and release structures. When subjected to impact, the stress generated lacks buffering and will be directly transmitted to the photovoltaic laminate, leading to glass breakage. The other type of frame adopts an open single C-shaped frame structure. This structure can provide buffering against forces, but its overall strength is insufficient. It is prone to deformation under stress. For example, when subjected to lateral or torsional forces, the single C-shaped frame is prone to irreversible deformation, resulting in insufficient support strength for the single-glass module.
[0004] In existing technologies, to address the shortcomings of the two types of frames mentioned above, additional reinforcement devices are typically added. These include metal reinforcing ribs, buffer blocks, locking mechanisms, or additional support frames installed inside or outside the frame. While these structures can improve strength or increase cushioning to some extent, their drawbacks are also obvious. First, installation is complex and time-consuming, requiring additional installation by technicians. When the photovoltaic array is large, this can lead to a significant workload and long installation time. Second, after installation, locking mechanisms or support frames require adjustment and maintenance. When the environment changes, all devices need to be adjusted, which is also time-consuming. Finally, the cost of the equipment increases significantly due to the addition of additional reinforcement devices, thus requiring improvement. Utility Model Content

Detailed Implementation
[0026] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0027] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, 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, and should not be construed as limiting the specific protection scope of this application.
[0028] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0029] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.
[0030] A preferred embodiment of this application, such as Figures 1 to 4 As shown, a single-glass module frame reinforcement structure resistant to mechanical stress includes an upper frame and a lower frame, which are integrally formed. The upper frame is provided with a mounting groove 14 for assembly with photovoltaic laminates. The lower frame includes a double C-shaped frame and an interlocking part. The double C-shaped frame is located below the mounting groove 14 and shares a side plate with the mounting groove 14. The interlocking part includes a first movable section 11 and a second movable section 12. The first movable section 11 and the second movable section 12 are respectively fixedly disposed on the upper and lower sides of the opening of the double C-shaped frame. The two ends of the first movable section 11 and the second movable section 12 that are close to each other interlock to form an interlocking part.
[0031] Compared to the single C-shaped frame in the prior art, the double C-shaped frame significantly enhances strength and improves bending and torsional resistance. The double C-shaped frame features an interlocking first movable section 11 and a second movable section 12 at the opening, forming a rectangular frame similar to those in the prior art, further increasing strength. The interlocking ends of the first movable section 11 and the second movable section 12 retain mobility; upon impact, the interlocking parts can move and deform to provide cushioning, preventing stress from directly impacting the photovoltaic laminate and causing glass panel breakage. Therefore, the frame structure in this application combines strength and cushioning performance. Furthermore, since the aforementioned structure is the frame body, it is manufactured as a single piece, unlike the additional reinforcement structures required in the prior art, resulting in significantly lower costs and eliminating the need for time-consuming and labor-intensive installation and debugging.
[0032] In this embodiment, the first movable segment 11 is provided with a first biting hook 111 at its end, and the second movable segment 12 is provided with a second biting hook 121 at its end. The first biting hook 111 and the second biting hook 121 hook each other. When the double C-shaped frame is impacted and its opening tends to open, the first biting hook 111 and the second biting hook 121 interact with each other to restrict the opening from opening.
[0033] The impact conditions described above can be considered as a fixed whole, which is connected with the double C-shaped frame to form a rectangular frame similar to the prior art. At the same time, there is a C-shaped frame inside as reinforcement, which further improves its strength and makes it more resistant to bending and torsion.
[0034] Furthermore, after the first biting hook 111 and the second biting hook 121 are hooked together and fit tightly, the lower part of the first movable segment 11 is squeezed and bends to one side, and the upper part of the second movable segment 12 is squeezed and bends to the other side.
[0035] It is understandable that, such as Figure 3As shown, the upper part of the first movable segment 11 and the lower part of the second movable segment 12 are vertically collinear. Therefore, when the first engaging hook 111 and the second engaging hook 121 engage, the lower part of the first movable segment 11 will inevitably bend and shift to one side, and the upper part of the second movable segment 12 will bend and shift to the other side. At the same time, due to the elastic restoring force of the first movable segment 11 and the second movable segment 12 themselves, the first engaging hook 111 and the second engaging hook 121 will fit tightly together and not separate, ensuring that the first movable segment 11 and the second movable segment 12 have sufficient strength when subjected to the pulling force at the upper and lower ends. That is, when the double C-shaped frame is impacted and the opening tends to open, the first engaging hook 111 and the second engaging hook 121 engage with each other and fit tightly together, and their interaction force directly restricts the opening from opening.
[0036] Furthermore, when the double C-shaped frame is impacted and its opening tends to close, the first engagement hook 111 and the second engagement hook 121 move away from each other, and the lower part of the first movable segment 11 and the upper part of the second movable segment 12 both shift further toward the bending side. The first engagement hook 111 and the second engagement hook 121 are subjected to greater mutual compression. When the impact ends, the first engagement hook 111 and the second engagement hook 121 return to their original positions under the action of the elastic restoring force of the first movable segment 11 and the second movable segment 12.
[0037] Because the occlusal part is movable, it has a buffering capacity. When an impact causes the opening to tend to close, the first occlusal hook 111 and the second occlusal hook 121 move away from each other, converting the impact force into displacement. The first movable segment 11 and the second movable segment 12 bend and shift further, increasing the compression between the first occlusal hook 111 and the second occlusal hook 121 and dissipating more energy. In this way, the corresponding force is buffered. After the impact ends, the first movable segment 11 and the second movable segment 12 themselves have elastic restoring force, which can drive the first occlusal hook 111 and the second occlusal hook 121 to automatically reset. The structure returns to its original state, avoiding permanent deformation, and can still buffer the impact the next time it is encountered.
[0038] Furthermore, such as Figures 4 to 5 As shown, both the first and second occlusal hooks 121 are single hooks; or both the first and second occlusal hooks 111 and 121 are serrated hooks; or the first occlusal hook 111 is a single hook and the second occlusal hook 121 is a serrated hook; or the first occlusal hook 111 is a serrated hook and the second occlusal hook 121 is a single hook.
[0039] The shapes of the first biting hook 111 and the second biting hook 121 can be set according to actual needs. For example, in a relatively stable environment, a single hook shape can be selected. This shape can meet the strength and buffering requirements under conditions without drastic stress changes. However, in a state of high environmental impact, such as drastic wind pressure changes, a single hook shape may not meet the requirements. Severe stress impact can easily lead to failure of the biting part. In this case, a serrated hook shape can be used, with multiple serrations hooking together to improve the strength of the biting part and resist severe stress impact. At the same time, the specific number of serrations hooked can be adjusted according to the actual situation to adjust the squeezing force between the first biting hook 111 and the second biting hook 121, thereby further reducing the movement impact of the biting part and improving its impact resistance.
[0040] Furthermore, such as Figure 6 As shown, a first buffer pad 112 is fixedly provided on the first bite hook 111, and a second buffer pad 122 is fixedly provided on the second bite hook 121. After the first bite hook 111 and the second bite hook 121 hook each other, the first buffer pad 112 and the second buffer pad 122 fit tightly together.
[0041] The buffer pad further enhances its ability to buffer stress impacts, while increasing the friction between the first engagement hook 111 and the second engagement hook 121 to prevent disengagement. Of course, in other embodiments, the force between the first engagement hook 111 and the second engagement hook 121 can also be increased by setting a magnet to improve the buffering ability and prevent disengagement.
[0042] In this embodiment, the double C-shaped frame includes a second vertical segment 3, a fifth horizontal segment 8, a fifth vertical segment 10, a fourth horizontal segment 7, a third vertical segment 6, a third horizontal segment 5, a fourth vertical segment 9, and a second horizontal segment 4 connected end to end. After connection, a C-shaped cavity 16 is formed inside the double C-shaped frame. The first movable segment 11 is fixedly disposed on the lower side of the third horizontal segment 5, and the second movable segment 12 is fixedly disposed on the upper side of the fourth horizontal segment 7. A compression cavity 17 is formed between the third horizontal segment 5, the third vertical segment 6, the fourth horizontal segment 7, the first movable segment 11, and the second movable segment 12. The mounting groove 14 is formed by sequentially connecting the first horizontal segment 1, the first vertical segment 2, and the second horizontal segment 4. The opening direction of the mounting groove 14 is consistent with the opening direction of the double C-shaped frame.
[0043] Based on the existing structure, the added third horizontal segment 5, third vertical segment 6, and fourth horizontal segment 7 form an internal C-shaped frame, thus constituting a double C-shaped frame. This frame has higher strength than a single C-shaped frame. The internal C-shaped frame can be understood as a special reinforcing rib, but it is not simply a reinforcing rib. It forms a rectangular frame with buffering capacity together with the first movable segment 11 and the second movable segment 12. The compression cavity 17 formed by the rectangular frame can provide deformation space after impact. Therefore, the internal C-shaped frame, on the one hand, constitutes part of the double C-shaped frame, providing higher strength, and on the other hand, as a component of the compression cavity 17, together with the first movable segment 11 and the second movable segment 12, enables the lower frame to have buffering capacity.
[0044] Furthermore, the length of the first horizontal segment 1 is shorter than the length of the second horizontal segment 4. An overflow groove 13 is provided on the side of the first horizontal segment 1 facing the second horizontal segment 4. Material-stealing grooves 15 are provided on both the upper and lower frames. The cross-section of the material-stealing groove 15 is an isosceles trapezoid. The material-stealing groove 15 can reduce the weight of the frame on the one hand, and increase the bending and torsional strength of the frame on the other hand.
[0045] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
