Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic cells, in particular to a frame and a photovoltaic component. Background Art
[0002] In order to facilitate the transportation of photovoltaic modules, multiple photovoltaic modules are usually stacked together. Since the surface of photovoltaic modules is relatively smooth, adjacent photovoltaic modules are prone to relative sliding, which in turn causes instability of the stacked photovoltaic modules. In order to enhance the stability of stacked photovoltaic modules, some existing photovoltaic modules are provided with limiting structures on the frame. The limiting structures usually include matching concave structures and convex structures. The convex structure is formed at the top or bottom of the frame, and the concave structure is correspondingly formed at the bottom or top of the frame. When the photovoltaic modules are stacked, the top of the frame of the lower photovoltaic module contacts the bottom of the frame of the upper photovoltaic module, so that the convex structure is combined with the concave structure to limit the relative sliding of adjacent photovoltaic modules.
[0003] Existing photovoltaic modules form a limiting structure through the cooperation of the concave structure and the convex structure of the frame. When the limiting structure is formed on the front, rear, left and right sides of the photovoltaic module, the photovoltaic module may be over-positioned, which not only increases the difficulty of manufacturing and assembling the frame, but also causes the photovoltaic module to slide relative to each other because the concave structure and the convex structure cannot fully fit together, thereby increasing the difficulty of transportation.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0036] Embodiment 1
[0037] See Fig.12 Since the existing photovoltaic modules form a limiting structure through the concave structure 41 and the convex structure 40 of the frame, the limiting structure can simultaneously limit the positive and reverse sliding of adjacent photovoltaic modules in the lateral direction of the frame. Each photovoltaic module is provided with a frame on the front, rear, left and right sides, so that the limiting structures are formed on the opposite sides of the photovoltaic module.
[0038] Since the limiting structures on both sides can limit the forward and reverse sliding of the photovoltaic components, the degree of freedom of the photovoltaic components is repeatedly limited, causing the photovoltaic components to be over-positioned. The over-positioned photovoltaic components have extremely high requirements for the manufacturing accuracy and assembly accuracy of the front, rear, left and right side frames, which greatly increases the manufacturing difficulty and assembly difficulty of the frame. If there is a certain deviation in the frame during the production and assembly process, it is easy to cause the concave structure 41 of the front, rear, left and right side frames of the photovoltaic component to be unable to combine with the convex structure 40, which will cause the stacked photovoltaic components to slide relative to each other and cause damage, further increasing the difficulty of transporting the photovoltaic components. Therefore, it is necessary to provide a new frame and photovoltaic component to address the above problems.
[0039] like Figure 1 As shown, this embodiment discloses a photovoltaic assembly, which includes a solar glass panel 10 and a frame 20 disposed on at least one opposite side of the front, rear, left and right of the solar glass panel 10. Figure 2-3 As shown, the frame 20 of this embodiment includes a frame body, the top of the frame body has a first protrusion 30, the bottom of the frame body has a second protrusion 31, and in horizontal projection, the first protrusion 30 and the second protrusion 31 are staggered in the lateral direction of the frame 20. Figure 4-5The photovoltaic modules of this embodiment are stacked in the vertical direction by default, the top of the frame 20 of the lower photovoltaic module contacts the bottom of the frame 20 of the upper photovoltaic module, and the first protrusion 30 of the lower frame 20 cooperates with the second protrusion 31 of the lower frame 20 to form a limiting structure, which can limit the upper photovoltaic module from sliding forward or backward relative to the lower photovoltaic module along the lateral direction of the frame 20. It should be noted that the photovoltaic modules of this embodiment can also be stacked in the horizontal direction according to needs. The principle of stacking photovoltaic modules in the vertical direction is the same as that in the horizontal direction, which will not be repeated here. The frame 20 of the present embodiment is at least configured on one of the opposite sides of the solar glass panel 10, that is, the frame 20 of the present embodiment can be set only on the long side of the solar glass panel 10 to form a long frame 20a; it can also be selected to set the frame 20 of the present embodiment only on the short side of the solar glass panel 10 to form a short frame 20b; the frame 20 of the present embodiment can also be set on both the long and short sides of the solar glass panel 10. When the long frame 20a and the short frame 20b both have the first protrusion 30 and the second protrusion 31, the shape and size of the cross-section of the long frame 20a and the short frame 20b can be exactly the same, or the shape and / or size of the cross-section of the long frame 20a and the short frame 20b can be different according to needs.
[0040] The frame 20 of the present embodiment forms a limiting structure by means of the first protrusion 30 and the second protrusion 31 which are arranged in a staggered manner. On one side of the stacked photovoltaic components, the limiting structure is used to limit the distance between the second protrusion 31 of the upper photovoltaic component and the first protrusion 30 of the lower photovoltaic component, but does not limit the distance between the first protrusion 30 and the second protrusion 31. In other words, the limiting structure on one side can only limit the one-way (forward or reverse) sliding of the photovoltaic component, and the stacked photovoltaic components need to limit the forward sliding and the reverse sliding at the same time by the limiting structures on both sides. Therefore, the frame 20 of the present embodiment can avoid the situation where the photovoltaic components are over-positioned. The misaligned distance between the first protrusion 30 and the second protrusion 31 can balance the errors that occur in the manufacturing and assembly process of the frame 20, effectively reducing the production difficulty of the photovoltaic components, and ensuring that the photovoltaic components can be smoothly stacked together and play a limiting role.
[0041] It should be noted that the forward sliding and reverse sliding of the present embodiment are for the convenience of describing the degrees of freedom of the photovoltaic assembly. According to the position of the limiting structure, the forward direction may refer to any direction of forward, backward, left and right, and the reverse direction corresponds to the backward, forward, right and left directions respectively. When the limiting structure is formed on the left or right side of the photovoltaic assembly, the forward direction is the left or right direction; when the limiting structure is formed on the front or rear side of the photovoltaic assembly, the forward direction is the forward or backward direction. The misaligned setting of the present embodiment specifically refers to that the horizontal projections of the first protrusion 30 and the second protrusion 31 are not in contact. When the photovoltaic assemblies are aligned and stacked, the second protrusion 31 of the upper photovoltaic assembly can move a certain distance in the direction of approaching relative to the first protrusion 30 of the lower photovoltaic assembly.
[0042] like Figure 2-5 The frame body of this embodiment specifically includes an A surface 21, a B surface 22 and a C surface 23, wherein the A surface 21 forms the top of the frame body, the C surface 23 forms the bottom of the frame body, and the B surface 22 connects the A surface 21 and the C surface 23; a first connecting end is formed at the connection between the A surface 21 and the B surface 22, and a second connecting end is formed at the connection between the C surface 23 and the B surface 22; a first protrusion 30 is formed on the A surface 21 and protrudes upward relative to the A surface 21, and a second protrusion 31 is formed on the C surface 23 and protrudes downward relative to the C surface 23.
[0043] See Figure 2 and Figure 5 In this embodiment, the second protrusion 31 is preferably arranged on a side close to the second connection end, so that there is a certain distance between the first protrusion 30 and the first connection end. When the photovoltaic modules are stacked, the first protrusion 30 of the lower photovoltaic module can limit the second protrusion 31 of the upper photovoltaic module from moving onto the solar glass panel 10, thereby preventing the second protrusion 31 of the upper photovoltaic module from interfering with the solar glass panel 10 of the lower photovoltaic module.
[0044] See Figure 3 In this embodiment, the first protrusion 30 may be set on a side close to the second connection end, so that the second protrusion 31 is at a certain distance from the second connection end. There is enough space between the first protrusion 30 and the second protrusion 31, and a suitable offset distance can be set according to needs.
[0045] See Figure 5In this embodiment, the distance h1 of the first protrusion 30 protruding from the A surface 21 is preferably equal to the distance h2 of the second protrusion 31 protruding from the C surface 23. When the photovoltaic modules are stacked, the first protrusion 30 of the lower photovoltaic module abuts against the C surface 23 of the upper photovoltaic module, and the second protrusion 31 of the upper photovoltaic module abuts against the A surface 21 of the upper photovoltaic module. The lower photovoltaic module supports the upper photovoltaic module through the first protrusion 30 and the second protrusion 31 at the same time, which helps to improve the stability of the photovoltaic module stacking.
[0046] In some embodiments, the distance that the first protrusion 30 protrudes from the A surface 21 can be greater or less than the distance that the second protrusion 31 protrudes from the C surface 23 according to the needs. For example, when the first protrusion 30 is close to the first connection end, the distance h1 that the first protrusion 30 protrudes from the A surface 21 can be greater than the distance h2 that the corresponding second protrusion 31 protrudes from the C surface 23. At this time, the first protrusion 30 mainly plays a supporting role, and the force on the second protrusion 31 close to the solar glass panel 10 is smaller, which can effectively improve the situation of damage to the solar glass panel 10. Similarly, when the second protrusion 31 is close to the second connection end, the distance that the second protrusion 31 protrudes from the C surface 23 can be greater than the distance that the corresponding first protrusion 30 protrudes from the A surface 21.
[0047] It should be noted that the frame body of the present embodiment can be a conventional frame having an A-side 21; a groove structure 26 can also be formed on the frame body of the present embodiment, and the groove structure 26 can be combined with the tenon structure of the purlin to form a connecting component. For details of the connecting component, please refer to the patent application document with application number 202080005546.X.
[0048] Embodiment 2
[0049] This embodiment discloses a photovoltaic module, which differs from the first embodiment mainly in the structure of the frame body. Figure 6-8As shown, the frame body of this embodiment has no A surface 21, and the frame body specifically includes a main support section 24, a B surface 22, a C surface 23, and a side support section 25 protruding from the main support section 24 from the B surface 22, wherein the top of the side support section 25 forms the top of the frame body, the C surface 23 forms the bottom of the frame body, the B surface 22 connects the main support section 24 and the C surface 23, the main support section 24 is used to support the bottom of the solar glass panel 10, and the side support section 25 is used to support the side wall of the solar glass panel 10. In the photovoltaic assembly of this embodiment, the distance H of the side support section 25 of the frame 20 protruding from the main support section 24 is equal to or greater than the thickness of the solar glass panel 10, so that the top of the side support section 25 is not lower than the upper surface of the solar glass panel 10. The first protrusion 30 of this embodiment is formed at the top of the side support section 25 and protrudes upward relative to the top, and the second protrusion 31 of this embodiment is formed on the C surface 23 and protrudes downward relative to the C surface 23. The first protrusion 30 can not only cooperate with the second protrusion 31 to form a limiting structure, but also protect the solar glass panel 10 and enhance the side anti-collision effect of the solar glass panel 10 .
[0050] See Figure 6-9 The first protrusion 30 and the second protrusion 31 are preferably arranged on both sides of the corresponding side support section 25. When the photovoltaic modules are stacked, the second protrusion 31 of the upper photovoltaic module is usually located within the horizontal projection range of the support section, which can prevent the second protrusion 31 from affecting the solar glass panel 10 of the lower photovoltaic module.
[0051] See Figure 6 , 8 9, the first protrusion 30 can be arranged on a side close to the solar glass panel according to the requirements, and the second protrusion 31 is arranged close to the connection end of the B surface 22 and the C surface 23 to maintain the misalignment distance between the first protrusion 30 and the second protrusion 31. The first protrusion 30 is close to the solar glass panel 10 of the photovoltaic module, which can improve the protection effect of the solar glass panel 10.
[0052] See Figure 10-11 When the photovoltaic modules are stacked, the first protrusion 30 of the lower photovoltaic module can limit the second protrusion 31 of the upper photovoltaic module from moving to the solar glass panel 10, thereby preventing the second protrusion 31 of the upper photovoltaic module from damaging the solar glass panel 10 of the lower photovoltaic module.
[0053] See Figure 7The first protrusion 30 can be arranged on a side away from the solar glass panel according to the requirements, and the second protrusion 31 has a spacing with the connection ends of the B surface 22 and the C surface 23 to maintain the misalignment distance between the first protrusion 30 and the second protrusion 31. The first protrusion 30 is away from the solar glass panel 10 of the photovoltaic module, which can effectively prevent the first protrusion 30 from blocking the solar glass panel 10.
[0054] See Fig.11 The distance h3 of the first protrusion 30 protruding from the side support section 25 is preferably equal to the distance h4 of the second protrusion 31 protruding from the C-surface 23. When the photovoltaic modules are stacked, the lower photovoltaic modules support the upper photovoltaic modules through the first protrusion 30 and the second protrusion 31 at the same time, which helps to improve the stability of the photovoltaic module stacking.
[0055] In some embodiments, the distance h3 of the first protrusion 30 protruding from the side support section 25 can be greater than or less than the distance h4 of the second protrusion 31 protruding from the C surface 23 according to the needs. For example, when the first protrusion 30 is arranged far away from the solar glass panel 10, the distance h3 of the first protrusion 30 protruding from the side support section 25 is equal to or greater than the distance h4 of the corresponding second protrusion 31 protruding from the C surface 23. At this time, the first protrusion 30 mainly plays a supporting role, while the force on the second protrusion 31 close to the solar glass panel 10 is small, which can effectively improve the situation of damage to the solar glass panel 10. Similarly, when the second protrusion 31 is close to the connection end of the B surface 22 and the C surface 23, the distance of the second protrusion 31 protruding from the C surface 23 is equal to or greater than the distance of the corresponding first protrusion 30 protruding from the side support section 25. For another example, when the second protrusion 31 is close to the connection end of the B surface 22 and the C surface 23, the distance h3 of the first protrusion 30 protruding from the side support section 25 is greater than the distance h4 of the second protrusion 31 protruding from the C surface 23. When the stacked photovoltaic components slide relatively, the first protrusion 30 of the lower photovoltaic component can always contact the C surface 23 of the upper photovoltaic component to prevent the upper photovoltaic component from shaking up and down.
[0056] The frame without the A surface 21 of this embodiment preferably has a groove structure 26 formed on the upper side of the C surface 23, and the groove structure 26 is used to cooperate with the tenon structure on the purlin, so that the groove structure 26 and the tenon structure are combined to form a connecting component to facilitate the connection between the frame 20 and the purlin. The connecting component is specifically referred to in the patent application document with application number 202080005546.X.
[0057] In this embodiment, the upper groove wall 27 of the groove structure 26 is formed with a locking element 28 at the opening. Figure 6-7 In this embodiment, the locking element 28 can be formed by protruding downward from the inner surface of the upper groove wall 27. Figure 8In this embodiment, the locking element 28 can also be formed by bending the upper groove wall 27 so that the upper groove wall 27 maintains the same thickness, thereby reducing the material used for the frame 20.
[0058] See Figure 8 The main support section 24 of this embodiment can be extended a certain distance in the direction away from the B surface 22 to increase the contact area between the main support section 24 and the solar glass panel 10, so that the main support section 24 can stably support the solar glass panel 10.
[0059] See Figure 6-8 In this embodiment, the frame body further includes a cavity 29 formed between the groove structure 26 and the main support section 24, and the cavity 29 is used to penetrate a right-angled cavity plug. The cavity plug is provided in the frame 20 on the adjacent side of the photovoltaic module to enhance the connection strength of the frame 20. Specifically, the frame 20 on the left or right side of the photovoltaic module is connected to the frame 20 on the front or rear side of the photovoltaic module through the cavity plug.
[0060] See Figure 8 The frame body of this embodiment can also select a conventional frame without the A surface 21. The frame body is provided with a mounting hole on the C surface 23, and bolts are inserted through the mounting hole to connect the frame 20 and the purlin. The side support section 25 of this embodiment is also provided with a glue overflow groove on the side away from the B surface 22, and the glue overflow groove can accommodate the glue for bonding the frame 20 and the solar glass panel 10 to prevent the glue from overflowing.
[0061] The photovoltaic module of this embodiment adopts a frame 20 without an A-side 21. The frame 20 is connected to the solar glass panel 10 only through a main support section 24 and a side support section 25. It can not only effectively prevent dust accumulation on the upper surface of the solar glass panel 10, but also make the upper surface of the solar glass panel 10 unobstructed, which helps to improve the power generation of the photovoltaic module.
[0062] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, 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.
[0063] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
