[0002] As the price of cells decreases, the proportion of auxiliary materials in photovoltaic modules is increasing. The frames of conventional photovoltaic modules are usually made of aluminum profiles. In order to reduce costs, the thickness of aluminum profiles has gradually become thinner, even reaching the load requirement limit, but it still accounts for more than 13% of the cost of photovoltaic modules.

[0046] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0047] The following is combined with Figure 1 To Attachment Fig.11 And a number of specific embodiments are used to introduce the technical solution provided by the utility model.

[0048] Embodiment 1

[0049] This embodiment provides a photovoltaic assembly frame for mounting a photovoltaic panel 100 on a photovoltaic bracket. Figure 1 As shown, the photovoltaic module frame includes a substrate layer 10, a buffer adhesive layer 20 and a reinforcement layer 30. The substrate layer 10 is used as the skeleton of the photovoltaic module frame and is made of metal material, thereby providing a good structural strength foundation for the photovoltaic module frame; the substrate layer 10 is fixedly connected to the periphery of the substrate layer 10 with a buffer adhesive layer 20, which is made of a composite material and thus has a preset elasticity and viscosity; the buffer adhesive layer 20 is fixedly connected to the periphery of the reinforcement layer 30, which is made of a hard plastic material, and the reinforcement layer 30 also has the performance of improving the strength of the photovoltaic module frame, thereby ensuring the load resistance strength of the photovoltaic module frame, and can save the consumables of the substrate layer 10, so that the substrate layer 10 can become thinner, reducing the production cost.

[0050] In this embodiment, by arranging the buffer adhesive layer 20 and the reinforcement layer 30 on the outer surface of the substrate layer 10, the surface protection of the substrate layer 10 can be formed, the risk of oxidation corrosion of the substrate layer 10 can be avoided, and the leakage problem of insulation can also be avoided. In addition, since the buffer adhesive layer 20 has a preset elasticity and adhesion, when the photovoltaic module is deformed by an external force, the buffer adhesive layer 20 can produce elastic deformation, absorb the external force, and ensure that the substrate layer 10 and the reinforcement layer 30 are firmly bonded, and delamination will not occur, thereby effectively improving the deformation resistance and structural strength of the photovoltaic module frame.

[0051] The substrate layer 10 can be manufactured using any one of aluminum, steel, copper or iron materials to ensure that the substrate layer 10 has the required structural strength while controlling the manufacturing cost and being easy to obtain, thereby improving production efficiency.

[0052] The buffer adhesive layer 20 can be manufactured using composite materials such as rubber, polyurethane, and silicone that have good elasticity and adhesive properties to ensure that the buffer adhesive layer 20 can effectively absorb impact and vibration and has strong adhesive stability.

[0053] The reinforcing layer 30 can be manufactured using hard plastic materials such as polypropylene and polyethylene, which can further improve the structural strength of the photovoltaic module frame. The overall weight is lighter than metal materials, which can reduce the load pressure of the photovoltaic bracket, thereby controlling the design cost of the photovoltaic bracket.

[0054] Optionally, in this embodiment, continue to refer to Figure 1 As shown, the weather-resistant layer 40 is also fixedly connected to the periphery of the reinforcement layer 30. The weather-resistant layer 40 can protect the appearance of the photovoltaic module frame and improve the weather resistance strength of the reinforcement layer 30, thereby further improving the service life of the photovoltaic module frame. When selecting the material for manufacturing the weather-resistant layer 40, it is necessary to consider the bonding performance with the reinforcement layer 30, as well as its own good chemical stability, weather resistance and other properties. Referring to the prior art, the weather-resistant layer 40 can be selected from any one of fluorocarbon compounds, polyester coatings, silicone resin coatings, etc., and the present utility model does not limit this.

[0055] Specifically, refer to Figure 1 As shown, in this embodiment, Figure 1 The photovoltaic module frame shown in the figure is arranged on the short side of the photovoltaic cell panel 100. The cross-sectional shape of the substrate layer 10 in the photovoltaic module frame is C-shaped, and includes a top frame 11, a middle frame 12 and a bottom frame 13. Among them, the top frame 11 is arranged parallel to the bottom frame 13, and the cross-sectional shape of the part of the reinforcing layer 30 located inside the photovoltaic module frame is an inverted L-shaped, and its two ends are respectively fixedly connected to the middle frame 12 and the bottom frame 13, so that it can be enclosed with the top frame 11 and the middle frame 12 to form an angle code cavity 50. In addition, an installation groove 60 is formed between the bottom frame 13, the top frame 11 and part of the middle frame 12, and the photovoltaic cell panel 100 is inserted into the installation groove 60.

[0056] In the above-mentioned setting, the assembly between the photovoltaic module frame and the photovoltaic panel 100 can be achieved by plug-in connection, thereby providing a stable installation position for the photovoltaic panel 100, and the formed angle code cavity 50 can effectively enhance the structural strength and stability of the photovoltaic module frame, so that the photovoltaic module frame can effectively resist the influence of factors such as the external environment and wind pressure, thereby extending its service life.

[0057] Embodiment 2

[0058] refer to Figure 2 As shown, this embodiment provides a photovoltaic module frame, and the position of the photovoltaic module frame is the same as the position of the photovoltaic module frame in Example 1, that is, both are arranged at the short side position of the photovoltaic panel 100. The difference is that the cross-sectional shape of the substrate layer 10 in this embodiment is a G-shape.

[0059] Specifically, the top frame 11 and the middle frame 12 in the substrate layer 10 have the same structural appearance as that of the first embodiment, but the cross-sectional shape of the bottom frame 13 is C-shaped, and the opening direction of the bottom frame 13 faces the middle frame 12, so that the bottom frame 13 and the middle frame 12 are jointly surrounded to form an angle code cavity 50. An installation groove 60 for inserting the photovoltaic cell panel 100 is formed between the bottom frame 13, the top frame 11 and part of the middle frame 12.

[0060] Through the above-mentioned arrangement, the bottom frame 13 can support the photovoltaic panel 100 together with the reinforcement layer 30, thereby effectively improving the supporting stability of the photovoltaic module frame on the bottom of the photovoltaic panel 100, so that the photovoltaic module frame can support heavier photovoltaic panels 100, thereby increasing the application range of the photovoltaic module frame.

[0061] Furthermore, both ends of the middle frame 12 are connected to the top frame 11 and one end of the bottom frame 13 by an integral molding method, so as to ensure the structural strength of the entire substrate layer 10 and save process steps. In addition, the other end of the bottom frame 13 is connected to the middle frame 12 through the reinforcing layer 30, so that the corner code cavity 50 forms a closed structure and eliminates the gap, thereby further improving the structural strength of the photovoltaic module frame, and saving the step of connecting the other end of the bottom frame 13 to the middle frame 12 by welding, thereby reducing the cost of process, labor and materials.

[0062] Embodiment 3

[0063] refer to Figure 3As shown, this embodiment provides a photovoltaic module frame, the location of the photovoltaic module frame is the same as that of the photovoltaic module frame in the first embodiment, that is, both are set at the short side of the photovoltaic cell panel 100, and in this embodiment, the gap between the middle frame 12 and the bottom frame 13 is filled by the reinforcing layer 30, so that the corner code cavity 50 forms a closed structure. Different from the second embodiment, the cross-sectional shape of the substrate layer 10 in this embodiment is S-shaped.

[0064] Specifically, the structural appearance of the top frame in the substrate layer 10 is the same as that of the first embodiment, but the cross-sectional shape of the middle frame 12 is L-shaped, and the cross-sectional shape of the bottom frame 13 is U-shaped. One end of the middle frame 12 is connected to the top frame 11, and the other end of the middle frame 12 is connected to one end of the bottom frame 13, and the bottom frame 13 and the middle frame 12 are jointly formed to form the above-mentioned corner code cavity 50. In addition, the top frame 11 and the middle frame 12 are surrounded to form a mounting groove 60 for inserting the photovoltaic panel 100. The above-mentioned arrangement can support the photovoltaic panel 100 together by the top frame 11 and the middle frame 12. Compared with the photovoltaic panel 100 made by the reinforcement layer 30 in the first embodiment, the support stability is stronger and the frame of the photovoltaic module is not easy to deform.

[0065] Embodiment 4

[0066] refer to Figure 4 As shown, this embodiment provides a photovoltaic module frame, and the location of the photovoltaic module frame is the same as that of the photovoltaic module frame in the first embodiment, that is, both are set at the short side of the photovoltaic cell panel 100. And similar to the third embodiment, the photovoltaic module frame is also surrounded by the top frame 11 and the middle frame 12 to form an installation groove 60 for the photovoltaic cell panel 100 to be inserted.

[0067] Specifically, the structural appearance of the top frame in the base layer 10 is the same as that of the first embodiment, but the cross-sectional shapes of the middle frame 12 and the bottom frame 13 are both L-shaped, so that the cross-sectional shape of the base layer 10 in this embodiment is in the shape of a "H". The two ends of the middle frame 12 are respectively connected to one end of the top frame 11 and the bottom frame 13, and the other end of the bottom frame 13 is connected to the middle frame 12 through a part of the reinforcement layer 30, so that the middle frame 12, the bottom frame 13 and the reinforcement layer 30 are jointly surrounded to form the corner code cavity 50.

[0068] In the above arrangement, one side of the corner code cavity 50 is formed by the reinforcing layer 30, thereby saving consumables of the substrate layer 10 on one side, thereby helping to save production costs and the weight of the entire photovoltaic module frame, and reducing the load pressure of the photovoltaic bracket.

[0069] Embodiment 5

[0070] refer to Figure 5 As shown, this embodiment provides a photovoltaic module frame, in which the cross-sectional shape of the substrate layer 10 is the same as the cross-sectional shape of the substrate layer 10 in the first embodiment, that is, both are C-shaped. The difference is that the photovoltaic module frame in this embodiment is installed at the long side position supporting the photovoltaic cell panel 100.

[0071] Specifically, the photovoltaic module frame also includes a support portion 70, which is horizontally arranged and fixedly connected to the bottom frame 13. When the photovoltaic module frame is placed on the photovoltaic bracket, the support portion 70 abuts against the photovoltaic bracket to increase the supporting performance of the photovoltaic module frame. In this embodiment, after a part of the bottom frame 13 is extended outward, the above-mentioned support portion 70 is formed, thereby being able to meet the structural strength requirements of the support portion 70 under actual working conditions and being easy to produce.

[0072] Embodiment 6

[0073] refer to Figure 6 As shown, this embodiment provides a photovoltaic module frame, in which the cross-sectional shape of the substrate layer 10 is the same as the cross-sectional shape of the substrate layer 10 in the second embodiment, that is, both are G-shaped, and the photovoltaic module frame also includes a support portion 70, which is installed at the long side position supporting the photovoltaic cell panel 100. Different from it, in this embodiment, part of the reinforcement layer 30 attached to the bottom frame 13 is protruded outward to form the above-mentioned support portion 70, so that the photovoltaic module frame can be applied to the photovoltaic cell panel 100 with a smaller load requirement, which not only meets the support requirements, but also avoids the situation where the use of the substrate layer 10 to form the support portion 70 leads to an increase in the cost of consumables.

[0074] Embodiment 7

[0075] refer to Figure 7 As shown, this embodiment provides a photovoltaic assembly frame, and the location of the photovoltaic assembly frame is the same as the location of the photovoltaic assembly frame in the first embodiment, that is, both are arranged at the short side position of the photovoltaic panel 100.

[0076] Different from the photovoltaic module frame in the first embodiment, in this embodiment, one end of the top frame 11 in the substrate layer 10 is connected to one end of the middle frame 12, one end of the middle frame 12 is connected to one end of the bottom frame 13, and the other end of the bottom frame 13 is bent toward the direction close to the middle frame 12 and can be enclosed with the middle frame 12 to form an angle code cavity 50. In addition, part of the reinforcement layer 30 located at the middle frame 12 is protruding from the middle frame 12, so that the top frame 11, the middle frame 12 and part of the reinforcement layer 30 are enclosed together to form an installation groove 60 for inserting and installing the photovoltaic panel 100.

[0077] Furthermore, in this embodiment, if Figure 8 As shown, the photovoltaic module frame also includes a drainage structure 80, which is installed between two adjacent photovoltaic module frames, and a drainage groove 801 is provided on the drainage structure 80, and part of the drainage groove 801 is connected to the matching gap between the photovoltaic module frame and the photovoltaic battery panel 100, as shown in FIG. Figure 8 The drainage grooves 801 are located on both sides of the drainage structure 80, and the other part of the drainage grooves 801 are connected to the gap between two adjacent photovoltaic module frames, such as Figure 8 The drainage groove 801 is located in the middle side of the drainage structure 80. Due to the reasons of process quality, service life increase, installation method, etc., the photovoltaic module frame and the photovoltaic battery panel 100 are not tightly fitted, and there is an assembly gap between two adjacent photovoltaic module frames, so impurities such as rainwater will flow into the house through the gap between the photovoltaic module frame and the photovoltaic battery panel 100 and between two adjacent photovoltaic module frames. By setting the drainage structure 80, rainwater can be collected and discharged outside the house, thereby ensuring the cleanliness of the indoor environment and ensuring the safety of the use environment.

[0078] Specifically, Fig. 9 As shown, the drainage structure 80 includes a skeleton layer 81, an adhesive layer 82 and a reinforcement layer 83. The skeleton layer 81 is similar to the base material layer 10 in the first embodiment, and both are manufactured by metal materials to provide basic bearing capacity for the drainage structure 80; the adhesive layer 82 is similar to the buffer adhesive layer 20 in the first embodiment, and both are manufactured by composite materials to firmly connect the reinforcement layer 83 to the skeleton layer 81 and effectively improve the deformation resistance and structural strength of the drainage structure 80; the reinforcement layer 83 is similar to the reinforcement layer 30 in the first embodiment, which can further improve the structural strength of the drainage structure 80 and can effectively reduce the thickness of the skeleton layer 81, thereby reducing manufacturing costs and reducing the bearing pressure of the photovoltaic bracket.

[0079] Embodiment 8

[0080] The present embodiment provides a photovoltaic module frame, which is different from the first embodiment in that the photovoltaic module frame also includes a shielding portion 90, which can shield the matching gap between two adjacent photovoltaic module frames to prevent rainwater and other impurities from flowing into the house through the gap, thereby maintaining indoor dryness.

[0081] refer to Fig.10As shown, in this embodiment, a shielding portion 90 is provided on the photovoltaic module frame on one side (which can be a short side or a long side) of a photovoltaic cell panel 100. The shielding portion 90 is made of metal material, and the shielding portion 90 and the substrate layer 10 are fixedly connected by the reinforcing layer 30, and there is a matching groove 200 and a mounting groove 60 for inserting the photovoltaic cell panel 100 between the shielding portion 90 and the substrate layer 10, and the opening direction of the matching groove 200 is opposite to the opening direction of the mounting groove 60.

[0082] refer to Fig.11 As shown, in this embodiment, the cross-sectional shape of the substrate layer 10 in the photovoltaic module frame on the side opposite to one of the above-mentioned side edges is a Z-shaped shape, and the bottom frame 13 in the substrate layer 10 is configured to support Fig.10 In the photovoltaic module frame shown in the figure, part of the reinforcement layer 30 can be enclosed with the middle frame 12 to form an angle code cavity 50, and part of the reinforcement layer 30 constituting the angle code cavity 50 protrudes outward to form a limit column 301 that can be inserted into the matching groove 200. In addition, in the photovoltaic module frame, part of the reinforcement layer 30 located on the middle frame 12 is extended outward, and the extension direction is parallel to the axial direction of the top frame 11, so that the top frame 11, part of the middle frame 12 and part of the reinforcement layer 30 extending outward are enclosed together to form an installation groove 60.

[0083] Through the above arrangement, the matching gap between two adjacent photovoltaic assembly frames can be shielded by the shielding portion 90. Fig.12 As shown, rainwater is prevented from dripping into the house. Moreover, by inserting the limit column 301 into the matching groove 200, the assembly firmness between two adjacent photovoltaic component frames can be effectively improved, and the possibility of looseness can be reduced.

[0084] The present embodiment also provides a photovoltaic support, including a support body 1, a photovoltaic panel 100 and the above-mentioned photovoltaic module frame, wherein the photovoltaic module frame is installed around the photovoltaic battery package 100 and can fix the photovoltaic panel 100 to the support body 1. Since the photovoltaic module frame includes a substrate layer 10, a buffer adhesive layer 20 and a reinforcement layer 30, wherein the reinforcement layer 30 is made of a hard plastic material, the substrate layer 10 can be made thinner, thereby reducing the load pressure and production cost of the photovoltaic support and improving stability. By providing the buffer adhesive layer 20 and the reinforcement layer 30 on the outer surface of the substrate layer 10, the risk of oxidative corrosion of the substrate layer 10 can be avoided. In addition, since the buffer adhesive layer 20 can produce elastic deformation, it can absorb external forces, thereby ensuring the firmness of the photovoltaic module frame and preventing delamination, thereby effectively improving the reliability of the entire photovoltaic support.

[0086] More specifically, in this embodiment, a resistant layer 104 is further provided around the strengthening layer 103, and the resistant layer 104 can protect the appearance of the bracket body 1 and improve the weather resistance of the strengthening layer 103, thereby further improving the service life of the entire photovoltaic bracket. Referring to the first embodiment, the resistant layer 104 can also be manufactured by any material such as fluorocarbon compound, polyester coating, silicone resin coating, etc., and the utility model is not limited to this.
