[0037] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the drawings are exemplary. Below, reference is made to Figure 1 Describe the frame 100 according to the embodiment of the first aspect of the present utility model. The frame 100 can be used for the lightweight component 300. In the following description of the present application, the case where the frame 100 is used for the lightweight component 300 is taken as an example for illustration.

[0038] As Figure 1 shown, the frame 100 for the lightweight component 300 according to the embodiment of the first aspect of the present utility model includes a mounting part 1 and a support part 2.

[0039] Specifically, a mounting groove 11 extending along the length direction of the mounting part 1 (such as the front - rear direction shown) is formed on the mounting part 1, and the edge of the component body 301 of the lightweight component 300 is adapted to be fitted in the mounting groove 11. Figure 6 For example, in the examples of

[0040] , Figure 1 , Figure 3 and Figure 6 , taking the frame 100 on the right side of the component body 301 of the lightweight component 300 as an example for illustration. The mounting groove 11 extends in the front - rear direction, and the side of the mounting groove 11 facing the component body 301 of the lightweight component 300 is open. With such a setting, the mounting part 1 wraps the edge of the component body 301, protecting the edge of the component body 301 from being damaged, so that the component body 301 can be used normally for a long time. In addition, the mounting part 1 cooperates with the component body 301, improving the structural strength of the component body 301, thus preventing the lightweight component 300 from deforming, preventing the component body 301 from having hidden cracks during transportation and installation, further effectively protecting the lightweight component 300, preventing the power generation of the lightweight component 300 from being affected, and further enabling the lightweight component 300 to be used normally for a long time. Additionally, the setting of the mounting groove 11 not only facilitates the installation of the frame 100 and the component body 301, but also reduces the weight of the frame 100, reduces the mass of the lightweight component 300, and is easy to install on the roof.

[0041] Combined with Figure 1 andFigure 4 , the supporting part 2 is connected to one side in the thickness direction of the mounting part 1 (such as the up-and-down direction shown in Figure 1 ), and at least a part of the supporting part 2 is adapted to be fitted on the mounting bracket 200. For example, in the examples of Figure 1 and Figure 4 , the upper end surface of the supporting part 2 is connected to the lower side surface of the mounting part 1, and the lower part of the supporting part 2 is adapted to be fitted on the mounting bracket 200. When the frame 100 is used for the lightweight component 300, the frame 100 and the component body 301 can be connected by glue. The assembly process of the lightweight component 300 is generally as follows: First, inject glue into the mounting groove 11. Then, move the component body 301, and insert one side edge of the component body 301 into the mounting groove 11 so that one side of the component body 301 is bonded to the frame 100 by glue to form an integral body. Next, fit the lower part of the supporting part 2 of the frame 100 on the mounting bracket 200 on the roof. With such a setting, the supporting part 2 facilitates the assembly of the frame 100 and the mounting bracket 200, improving the assembly efficiency of the frame 100 and the mounting bracket 200. Moreover, the supporting part 2 can support the mounting part 1, improving the stability of the mounting part 1, thereby improving the stability of the frame 100, improving the assembly stability of the frame 100 and the component body 301, and further improving the use effect of the lightweight component 300. In addition, the structure of the frame 100 is simple, reducing the production difficulty, thereby increasing the production rate of the frame 100 and also reducing the production cost.

[0042] For the frame 100 of the lightweight component 300 according to the present utility model, the structure of the frame 100 is simple and the production and processing are convenient. When the frame 100 is used for the lightweight component 300, the mounting part 1 wraps the edge of the component body 301, and the mounting part 1 protects the edge of the component body 301, avoiding damage to the edge of the component body 301. Moreover, the mounting part 1 cooperates with the component body 301, improving the structural strength of the component body 301, thereby avoiding potential hidden cracks in the component body 301 during transportation and installation, and extending the service life of the lightweight component 300. In addition, the setting of the mounting groove 11 not only facilitates the installation of the frame 100 and the component body 301, but also reduces the weight of the frame 100, reducing the mass of the lightweight component 300 and making it easy to install on the roof. On the one hand, the supporting part 2 can support the mounting part 1, improving the assembly stability of the frame 100 and the component body 301. On the other hand, through the supporting part 2, it is also convenient to assemble the frame 100 and the mounting bracket 200, improving the installation efficiency of the frame 100 and the mounting support 200.

[0043] According to some embodiments of the present utility model, with reference to Figure 1, the installation part 1 includes a first installation section 12, a second installation section 13, and a third installation section 14. The second installation section 13 and the third installation section 14 are respectively connected to both sides of the first installation section 12 along the thickness direction of the installation part 1, and the second installation section 13 and the third installation section 14 are located on the same side of the first installation section 12 in the width direction (such as Figure 1 shown in the left - right direction). The second installation section 13, the third installation section 14, and the first installation section 12 together define an installation groove 11.

[0044] For example, in Figure 1 's example, both the second installation section 13 and the third installation section 14 are located on the left side of the first installation section 12, that is, both the second installation section 13 and the third installation section 14 are located on the side of the first installation section 12 facing the component body 301. The first installation section 12 extends in the up - down direction. The right end of the second installation section 13 is connected to one end of the first installation section 12 in the up - down direction, and the right end of the third installation section 14 is connected to the other end of the first installation section 12 in the up - down direction. The cross - sectional shape of the installation part 1 is roughly "U" - shaped.

[0045] With such a setting, the first installation section 12, the second installation section 13, and the third installation section 14 can protect the edge of the component body 301 from three sides, further avoiding damage to the component body 301. In addition, it also makes the side wall of the defined installation groove 11 cooperate with the edge of the component body 301, thereby improving the assembly stability of the frame 100 and the component body 301, preventing the frame 100 from falling off the component body 301, and further improving the use stability of the lightweight component 300. Additionally, the installation part 1 composed of the first installation section 12, the second installation section 13, and the third installation section 14 has a stable structure, improving the structural strength of the installation part 1, which helps to further improve the structural strength of the lightweight component 300.

[0046] According to some embodiments of the present utility model, referring to Figure 1 , the plane where the second installation section 13 is located is parallel to the plane where the third installation section 14 is located. For example, in Figure 1In the example, the plane where the second installation section 13 is located is parallel to the plane where the third installation section 14 is located in the left - right direction. With such a setting, the two opposite planes of the second installation section 13 and the third installation section 14 are easily and substantially completely attached to the two corresponding side surfaces of the component body 301 in the up - down direction, thereby further improving the installation stability of the installation part 1 and the component body 301, and further improving the use stability of the lightweight component 300. In addition, the structure of the installation part 1 is simple and easy to form, thus improving the production efficiency of the installation part 1. Moreover, the second installation section 13 and the third installation section 14 can have the same structure, and the second installation section 13 and the third installation section 14 can be produced simultaneously, which further improves the production efficiency of the installation part 1 and also reduces the production efficiency of the installation part 1. However, it is not limited to this. For example, the plane where the second installation section 13 is located is not parallel to the plane where the third installation section 14 is located (not shown in the figure).

[0047] According to some embodiments of the present utility model, referring to Figure 1 , the second installation section 13 is connected to the side of the first installation section 12 away from the support part 2, and the width of the second installation section 13 is w, where w satisfies: 10 mm ≤ w ≤ 11 mm. For example, the right end of the second installation section 13 is connected to the upper side surface of the first installation section 12. When the width w of the second installation section 13 is less than 10 mm, the width of the second installation section 13 is relatively small. During use, when the component body 301 is subjected to a large wind pressure, the protective effect of the second installation section 13 on the component body 301 is small, and the component body 301 is easily dropped from the frame 100, thereby shortening the service life of the component body 301. When the width w of the second installation section 13 is greater than 11 mm, the shielding area of the second installation section 13 on the surface of the component body 301 is relatively large, reducing the photoelectric conversion efficiency of the component body 301, and thus reducing the output power of the component body 301. Therefore, by setting the width w of the second installation section 13 to satisfy 10 mm ≤ w ≤ 11 mm, the width of the second installation section 13 is reasonably set, which not only improves the negative - pressure resistance of the lightweight component 300 and extends the service life of the lightweight component 300, but also ensures the output power of the lightweight component 300, further improving the use performance of the lightweight component 300. Moreover, it also enables the frame 100 to have a certain structural strength, which is beneficial to the long - term and stable use of the frame 100.

[0048] According to some embodiments of the present utility model, referring to Figure 1 , the support part 2 includes a support section 21 and a connection section 22. The support section 21 is opposite to the installation part 1 in the thickness direction of the installation part 1 (i.e., the up - down direction), and the connection section 22 is connected between the support section 21 and the installation part 1.

[0049] For example, in Figure 1In the example, the support section 21 extends in the left-right direction, the support section 21 is located at the lower side of the mounting portion 1, the upper end of the connecting section 22 is connected to the lower side of the mounting portion 1, and the lower end of the connecting section 22 is connected to the support section 21. As a result, the support section 21 increases the support surface of the support portion 2, that is, when the support portion 2 is assembled with the mounting bracket 200, the support section 21 increases the contact surface between the support portion 2 and the mounting bracket 200, thereby further improving the stability of the support portion 2, and further improving the installation stability of the component body 301, thereby further improving the use stability of the lightweight component 300. In addition, the support section 21 is connected to the mounting portion 1 through the connecting section 22, which has a simple structure, reduces the production cost, and improves the production rate.

[0050] According to some embodiments of the present invention, referring to Figure 1 , the connecting section 22 extends vertically along the thickness direction (i.e., the up-down direction) of the mounting portion 1. Figure 1 In the example, the connecting section 22 extends vertically in the up-down direction. In this way, the connecting section 22 vertically supports the mounting portion 1 in the up-down direction, which prevents the mounting portion 1 from shaking in the left-right direction, that is, it prevents the mounting portion 1 from shaking after long-term use, thereby improving the stability of the mounting portion 1. In addition, the length of the connecting section 22 in the up-down direction is shortened, the material consumption of the connecting section 22 is reduced, the production cost of the connecting section 22 is reduced, and thus the production cost of the frame 100 is reduced. However, it is not limited to this. For example, the connecting section 22 extends obliquely in the up-down direction, toward or away from the component body 301 (not shown in the figure).

[0051] According to some embodiments of the present invention, referring to Figure 1 The third mounting section 14 is connected to the side of the first mounting section 12 close to the support portion 2, one end of the connecting section 22 is connected to the side of the support section 21 facing the third mounting section 14, and the other end of the connecting section 22 is connected to the end of the third mounting section 14 away from the first mounting section 12.

[0052] For example, in Figure 1 In the example, the right end of the third mounting segment 14 is connected to the lower side of the first mounting segment 12, the lower end of the connecting segment 22 is connected to the upper side of the supporting segment 21, and the upper end of the connecting segment 22 is connected to the left side of the lower side of the third mounting segment 14. This arrangement improves the stability of the connection between the supporting portion 2 and the mounting portion 1, thereby improving the overall stability of the frame 100. In addition, the structure is simple, easy to use, and improves production efficiency. But it is not limited to this. For example, the upper end of the connecting segment 22 can be connected to the middle part or the right side of the lower side of the third mounting segment 14 (not shown in the figure), and can be specifically set according to actual usage conditions, thereby improving the installation flexibility of the mounting portion 1 and the supporting portion 2.

[0053] Optionally, the frame 100 is made of alloy steel, alloy aluminum or carbon fiber. The alloy steel part has special properties such as high strength, high toughness, wear resistance and corrosion resistance, which improves the structural strength of the frame 100, extends the service life of the frame 100, and also enhances the protection of the frame 100 for the component body 301, thereby extending the service life of the lightweight component 300. The alloy aluminum part and the carbon fiber part are lighter in weight and corrosion resistant, thus reducing the weight of the frame 100, facilitating transportation and installation, and also extending the service life of the lightweight component 300.

[0054] According to the mounting bracket 200 of the second aspect embodiment of the present utility model, referring to Figure 2 , a chute 201 is formed on the mounting bracket 200. The chute 201 extends through both side surfaces of the mounting bracket 200 along the length direction of the mounting bracket 200 (such as the front-back direction shown in Figure 6 ). At least a part of the supporting portion 2 of the frame 100 is adapted to be fitted in the chute 201 and is movable relative to the mounting bracket 200. The frame 100 is the frame 100 for the lightweight component 300 according to the first aspect embodiment of the present utility model.

[0055] For example, in the examples of Figure 2 , Figure 4 and Figure 6 , taking the frame 100 and the mounting bracket 200 on the right side of the component body 301 of the lightweight component 300 as an example for illustration. The chute 201 extends through the front side surface and the rear side surface of the mounting bracket 200. The lower part of the supporting portion 2 (i.e., the lower ends of the supporting section 21 and the connecting section 22 of the supporting portion 2) is located in the chute 201 and is movable relative to the mounting bracket 200 in the front-back direction, or slides out of the mounting bracket 200. With such a setting, it is convenient for the supporting portion 2 of the frame 100 to slide into or out of the mounting position of the mounting bracket 200 from the front end or the rear end of the chute 201, reducing the difficulty of assembling or separating the supporting portion 2 from the mounting bracket 200, thereby improving the assembling or disassembling efficiency of the frame 100 and the mounting bracket 200. In addition, the mounting bracket 200 is connected to the roof, and the lightweight component 300 is matched with the mounting bracket 200 through the frame 100, improving the stability of the lightweight component 300 installed on the roof.

[0056] According to some embodiments of the present utility model, referring to Figure 2 , an opening 202 is formed on the mounting bracket 200. The opening 202 is communicated with the chute 201. At least a part of the frame 100 is adapted to be fitted in the chute 201, and another part of the frame 100 is adapted to extend out through the opening 202. For example, in Figure 2In the example, the opening 202 is formed on the side of the mounting bracket 200 facing the mounting portion 1, the supporting section 21 of the frame 100 is adapted to fit in the slide groove 201, and the connecting section 22 of the frame 100 extends through the opening 202. Such an arrangement effectively ensures that the supporting portion 2 of the frame 100 can slide in the slide groove 201 and the opening 202, effectively ensures that the frame 100 and the mounting bracket 200 can be assembled normally, and improves the use performance of the mounting bracket 200.

[0057] According to some embodiments of the present invention, referring to Figure 2 , the width of the opening 202 is smaller than the width of the support segment 21 of the support portion 2. With such a configuration, after the frame 100 and the mounting bracket 200 are assembled, the side wall of the slide groove 201 limits the support segment 21, preventing the support segment 21 from sliding upward out of the slide groove 201 of the mounting bracket 200, thereby improving the assembly stability of the frame 100 and the mounting bracket 200, and further improving the use stability of the lightweight component 300.

[0058] According to the lightweight component 300 of the third aspect of the utility model, refer to Figure 3 , Figure 5 and Figure 6 , including a component body 301 and a plurality of frames 100. In the description of the present utility model, "multiple" means two or more. The frame 100 is a frame 100 for a lightweight component 300 according to the first embodiment of the present utility model. The plurality of frames 100 are arranged along the circumference of the component body 301, and the edges of the component body 301 are respectively matched with the corresponding mounting grooves 11 of the frame 100.

[0059] For example, in Figure 3 , Figure 5 , Figure 6 and Figure 7 In the example, four frames 100 are provided, and the four frames 100 are arranged along the circumference of the component body 301, and the four frames 100 are connected in sequence. In this way, the multiple frames 100 wrap the component body 301 from multiple angles, further improving the protection of the component body 301, and also improving the stability of the component body 301, thereby improving the use stability of the lightweight component 300.

[0060] Other structures and operations of the frame 100, the mounting bracket 200 and the lightweight component 300 according to the embodiment of the utility model are known to those skilled in the art and will not be described in detail here.
