[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] The following is combined with Figures 1 to 4 The following describes embodiments of the present invention.

[0025] According to an embodiment of the present invention, a frame connector is provided, comprising: a body 1, the body 1 having a first supporting horizontal plate 103 and a vertical limiting plate 102, the first supporting horizontal plate 103 and the vertical limiting plate 102 being vertically arranged, and an adhesive storage plate 101 extending from one end of the vertical limiting plate 102 away from the first supporting horizontal plate 103 toward the first supporting horizontal plate 103, the adhesive storage plate 101 being adapted to store adhesive, the adhesive storage plate 101, the vertical limiting plate 102 and the first supporting horizontal plate 103 forming an accommodating space 104 with an opening, the accommodating space 104 being adapted to accommodate a laminating component.

[0026] The design of the receiving space 104 allows the laminated component to enter the receiving space 104, and the adhesive stored in the glue storage plate 101 secures the connection between the main body 1 and the laminated component. This avoids the problem of insufficient glue storage space in the main body 1 causing adhesive to overflow from the laminated component, and also prevents overflow into the gaps between the frame connector and the laminated component, improving the durability and aesthetics of the laminated component. A vertical limiting plate 102 is used to precisely position and limit the laminated component, ensuring its fixed position. It is important to note that the laminated component completely fills the receiving space 104. Furthermore, the glue storage plate 101 prevents adhesive from overflowing the receiving space 104, ensuring sufficient glue quantity and maintaining the stability of the laminated component during use.

[0027] In one embodiment, such as Figure 1 As shown, the glue storage plate 101 is provided with a glue storage tank 1011, which is positioned facing the receiving space 104 and is used to hold adhesive. The glue storage tank 1011 is connected to the receiving space 104 and is used to hold adhesive to prevent the adhesive from overflowing outside the receiving space 104 when bonding laminates, that is, to avoid overflowing into the gap between the frame connector and the laminate. This increases the glue storage space and also ensures the overall aesthetics.

[0028] In one embodiment, such as Figure 1 As shown, the outer wall surface 1013 of the glue storage plate 101 is arc-shaped, and a rounded chamfer is provided between the glue storage plate 101 and the vertical limiting plate 102. The arc-shaped outer wall surface 1013 of the glue storage plate 101 enhances water resistance and optimizes water flow distribution during severe weather such as rain and snow, reducing water accumulation on the body 1 and preventing corrosion or mold caused by water accumulation. This allows for rapid drainage of the laminated components, effectively reducing maintenance costs. The rounded chamfer between the glue storage plate 101 and the vertical limiting plate 102 eliminates sharp angles and points on the body 1, preventing injury to personnel during installation and maintenance, and also improving wind resistance and reducing wind resistance. Furthermore, the arc-shaped outer wall surface 1013 of the glue storage plate 101 effectively reduces the shaded area, especially under low-angle sunlight in the early morning and evening, effectively improving the light reception efficiency of the laminated components.

[0029] In one embodiment, such as Figure 1 As shown, the glue storage tank 1011 is provided with a glue storage cantilever cavity 1014. The inner wall surface 1012 of the glue storage plate 101 is flat, and the glue storage cantilever cavity 1014 is set at an angle to the inner wall surface 1012 of the glue storage plate 101. The glue storage cantilever increases the amount of adhesive that can be contained in the glue storage tank 1011 without increasing the size of the glue storage plate 101. The glue storage cantilever cavity 1014 is set at an angle to the inner wall surface 1012 of the glue storage plate 101 (the inner wall surface 1012 of the glue storage plate 101 is parallel to the surface of the first support cross plate 103), and this angle ranges from 50° to 70°, preferably 60°. The glue storage cantilever cavity 1014 enhances the shock resistance of the glue storage plate 101, reduces the impact of external pressure or impact on the body 1, and avoids the laminate being loosely bonded due to insufficient adhesive. In this embodiment, the height of the glue storage plate 101 is 1-3mm, preferably 2mm; the length of the glue storage cantilever cavity 1014 is 1-2mm, and the width is 0.5-1mm.

[0030] In one embodiment, such as Figure 1 As shown, the main body 1 also includes a first vertical plate 105, a second vertical plate 106, and a second supporting horizontal plate 107. The first vertical plate 105 and the second vertical plate 106 are correspondingly arranged, and the vertical limiting plate 102 is located on the same side of the first vertical plate 105 as the first vertical plate 105. The first vertical plate 105, the second vertical plate 106, the first supporting horizontal plate 103, and the second supporting horizontal plate 107 form a closed supporting space 108. The supporting space 108 is hollow, which can reduce the overall weight of the main body 1 and enhance the structural stability of the main body 1.

[0031] In one embodiment, such as Figure 1 , Figure 3 As shown, the width of the second support horizontal plate 107 is greater than that of the first support horizontal plate 103, and a rounded chamfer is provided between the second support horizontal plate 107 and the first vertical plate 105. The rounded chamfer reduces the risk of injury to personnel during installation and maintenance, and also improves wind resistance and reduces wind resistance.

[0032] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the width of the glue storage plate 101 is smaller than that of the first support horizontal plate 103 to increase the light-receiving area on the surface of the laminate. In this application, the glue storage plate 101, the first support horizontal plate 103, the second support horizontal plate 107, the vertical limiting plate 102, the first vertical plate 105, and the second vertical plate 106 are integrally formed and made of the same material.

[0033] In one embodiment, such as Figure 2 ,Figure 3 As shown, the main body 1 includes a first connecting segment 109, a middle arc-shaped segment 110, and a second connecting segment 111 connected in sequence, with the first connecting segment 109 and the second connecting segment 111 arranged at right angles. The right angle arrangement is achieved through the first connecting segment 109 and the second connecting segment 111. It should be noted that the cross-sections of the first connecting segment 109, the middle arc-shaped segment 110, and the second connecting segment 111 are all identical, that is, each includes a glue storage plate 101, a first supporting horizontal plate 103, a second supporting horizontal plate 107, a vertical limiting plate 102, a first vertical plate 105, and a second vertical plate 106.

[0034] In one embodiment, such as Figure 2 , Figure 3 As shown, the first connecting segment 109 is provided with a first plug-in portion 112 at the end opposite to the middle arc segment 110, and the second connecting segment 111 is provided with a second plug-in portion 113 at the end opposite to the middle arc segment 110. The first plug-in portion 112 and the second plug-in portion 113 are respectively adapted to be plugged into the straight frame 2 to realize the plugging and fixing of the two straight frame 2.

[0035] In this embodiment, as Figure 2 , Figure 4 As shown, the first insertion portion 112 and the second insertion portion 113 are respectively provided with protruding ends 11301. The protruding ends 11301 fit against the inner sidewall of the straight frame 2 to increase the friction between the first insertion portion 112 and the straight frame 2, and between the second insertion portion 113 and the straight frame 2. Specifically, the protruding ends 11301 are serrated. In this embodiment, as... Figure 3 As shown, the outer side of the first vertical plate 105 of the first connecting section 109 is a cutout surface 1091, which is suitable for printing the manufacturer's logo to enhance the manufacturer's reputation.

[0036] According to an embodiment of this utility model, another aspect provides a photovoltaic frame, including a plurality of the aforementioned frame connectors and a plurality of straight frame members 2. It should be noted that each straight frame member 2 has a frame connector connected to one of its two sides, and the four frame connectors and four straight frame members 2 together form a rectangular shape to enclose the laminate. It should also be noted that the frame connectors and the straight frame members 2 are made of lightweight materials, such as aluminum or stainless steel.

[0037] According to an embodiment of this utility model, another aspect provides a photovoltaic module, including the aforementioned photovoltaic frame and a laminating component. Specifically, the laminating component includes: tempered glass, which protects the power generation unit—the solar cell—and requires high light transmittance (generally above 91%) and ultra-white tempering treatment; EVA, which serves to bond and fix the tempered glass and the power generation unit, directly affecting the module's lifespan and light transmittance; the power generation unit, which typically refers to a crystalline silicon solar cell or a thin-film solar cell; and a backsheet, which serves to seal, insulate, and waterproof, and is typically made of materials such as TPT and TPE.

[0038] The photovoltaic module provided in this application has the following advantages: (1) The combination design of straight frame 2 and frame connector optimizes the distribution and use of materials, making the photovoltaic module lighter and easier to install and transport. At the same time, it reduces weight, lowers overall cost, and improves product cost-effectiveness; (2) The design of rounded chamfers and curved surfaces avoids sharp edges and corners, effectively preventing injury to the human body, such as cuts and scratches, while improving the comfort and convenience of handling; (3) The design of the glue storage tank 1011 solves the problem of insufficient glue storage space in existing photovoltaic modules, which causes adhesive to overflow onto the glass surface of the laminate; (4) The combination design of frame connector and straight frame 2 not only ensures the power generation and power generation efficiency of the module, but also effectively enhances durability and (5) The first plug-in part 112 and the second plug-in part 113 are respectively provided with a protruding end 11301. The protruding end 11301 is attached to the inner side wall of the straight frame 2 to increase the friction between the first plug-in part 112 and the straight frame 2, and between the second plug-in part 113 and the straight frame 2. (6) The setting of the glue storage cantilever cavity 1014 enhances the shock resistance of the glue storage plate 101, reduces the impact of external pressure or impact on the body 1, and avoids the lamination of the laminate being not firmly bonded due to insufficient glue amount. (7) The outer wall surface 1013 of the arc-shaped glue storage plate 101 can effectively reduce the shadow area, especially in the early morning and at night under low-angle sunlight, effectively improving the light reception efficiency of the laminate.

[0039] As an alternative implementation, the width of the glue storage plate 101 may also be greater than or equal to the width of the first support plate 103.

[0040] As an alternative implementation, the width of the second support plate 107 may also be equal to that of the first support plate 103.
