Description

Technical Field

[0001] The utility model particularly relates to a mounting buckle for a non-A-side photovoltaic module. Background Art

[0002] With the development of the photovoltaic industry, more and more people begin to install photovoltaic modules on the roof; the photovoltaic module includes a module body and a frame. The module body refers to that solar cells are placed between two pieces of glass and then obtained by lamination. It is fragile and needs to be protected by the frame around. In order to better limit the module body, a clamping groove for clamping the module body is arranged on the frame, and this part of the clamping groove will be 3-5 mm higher than the glass surface. Therefore, the dust on the glass surface will accumulate on the glass surface near the clamping groove after being washed by rain. To solve this problem, a non-A-side frame (i.e., canceling the clamping groove) is introduced on the market now, which can reduce the accumulation of dust. During installation, the module body is adhered to the frame through a sealant. It takes a certain time for the sealant to be coated and cured. Before curing, its connection strength is weak, and at this time, the module body lacks the support of the clamping groove. Moreover, a junction box 3-3 needs to be installed on the frame (as Figure 7 shown), and only the module body can be placed downward. Therefore, the module body may be separated from the frame due to its own weight, ultimately affecting the assembly effect. Content of the Utility Model

Pressing the elastic piece 331 can drive the fixing button 332 to be connected to the glass clip or disconnect from the glass clip.

[0034] Further, the frame clip includes a base plate 113 and installation cavities 111 symmetrically provided on the base plate 113. The fixing members are arranged in both of the two installation cavities 111. One side of the base plate 113 is provided with a frame clip board 115 for buckling the module body, and the other side of the base plate 113 is provided with an assembly plate 116.

[0035] Further, the glass clip includes a glass fixing plate 223. Frame fixing plates 224 are respectively provided on one side of the glass fixing plate 223. A first limiting hole 221 corresponding to the fixing member is provided on each frame fixing plate 224, and one end of the fixing member is inserted into the first limiting hole 221.

[0036] Further, an assembly hole 117 for the fixing button 332 to pass through is formed on the assembly plate 116.

[0037] Further, a second limiting hole 222 is provided on the frame fixing plate 224 along the vertical direction.

[0038] Further, the elastic piece 331 and the fixing button 332 are connected by welding or riveting.

[0039] Further, both the frame clip and the glass clip are made of composite materials or plastic materials.

[0040] Further, the elastic piece 331 is made of elastic alloy steel or spring steel.

[0041] The working principle of the present utility model is as follows:

[0042] To better illustrate the design principle of this application, as Figure 1 shown, generally, the component body 2-2 is referred to as the A side, and the frame 1-1 is defined with B side, C side, and D side; first, an adhesive layer 4-4 (as Example 1, the adhesive layer can be selected as sealant) is coated between the component body 2-2 and the frame 1-1. During installation, first, the frame clamping plate 115 of the frame clamping part is buckled on the D side of the frame 1-1, the substrate 113 of the frame clamping part is closely attached to the C side of the frame 1-1, then the frame fixing plate 224 of the glass clamping part is closely attached to the B side of the frame 1-1, and the glass fixing plate 223 abuts against the A side (i.e., the glass surface) of the component body 2-2. As Example 1, the fixing parts are taken as the elastic sheet 331 and the fixing button 332. At this time, when pressing the elastic sheet 331, since the elastic sheet 331 has elasticity, pressing the elastic sheet 331 can drive one end of the fixing button 332 on the elastic sheet 331 to pass through the assembly hole 117 on the assembly plate 116 until it is connected to the first limiting hole 221, thus the frame fixing plate 224 and the assembly plate 116 can be connected and fixed; at this time, the space formed after the connection of the frame clamping part and the glass clamping part can limit the photovoltaic module. After the sealant between the frame 1-1 and the component body 2-2 is cured, press the elastic sheet 331 to make the elastic sheet 331 drive the fixing button 332 to disengage from the first limiting hole 221; thereby releasing the connection between the frame fixing plate 224 and the assembly plate 116, and thus the frame clamping part and the glass clamping part can be separated to release the limitation on the photovoltaic module (as Figure 6 shown). Since the sealant has been cured at this time, the connection strength between the component body 2-2 and the frame 1-1 is increased, and the phenomenon that the component body 2-2 detaches from the frame 1-1 due to its own weight is avoided.

[0043] Preferably, 2 installation cavities 111 are provided on the frame clamping part 1, and fixing parts are arranged in each installation cavity 111, then 2 assembly plates 116 are provided. Similarly, the connection principle of the other assembly plate, frame fixing plate, and fixing parts is the same as the above, so the working principle will not be elaborated again;

[0044] On the basis of the above technical solution, as Figure 8 shown, this application also provides a second limiting hole 222 on the frame fixing plate 224. When the fixing button 332 is connected to the second limiting hole 222, the space surrounded by the frame clamping part and the glass clamping part increases at this time, and the photovoltaic module can be taken down; when carrying out the assembly operation of the next photovoltaic module, the fixing button 332 is connected to the first limiting hole 221, and the space surrounded by the frame clamping part and the glass clamping part can limit the photovoltaic module at this time; thus, it is prevented that the frame clamping part and the glass clamping part are completely separated, and the assembly difficulty is reduced.

[0045] In the above technical solution, the height H from the rear frame clamping plate to the glass fixing plate after installation is less than the thickness W of the photovoltaic module.

[0046] Through experimental tests, it is proved that the frame clamping part and the glass clamping part are preferably made of composite material or plastic material, the elastic piece is made of elastic alloy steel or spring steel, and the fixing button is made of stainless steel. The elastic piece and the fixing button can be connected by welding or riveting; the frame clamping part and the glass clamping part are preferably formed by integral injection molding process.

[0047] After the component body and the frame of the present application are bonded through the adhesive layer, they are connected through the frame clamping part and the glass clamping part to form a space for limiting the photovoltaic module. After the adhesive layer is cured, the connection between the frame clamping part and the glass clamping part can be released. At this time, the space releases the limit on the photovoltaic module. Since the adhesive layer is in a cured state at this time, the connection strength between the component body and the frame is enhanced, and the component body is prevented from detaching from the frame due to its own weight.

[0048] Although the present invention has been described in detail with reference to the above embodiments, it is obvious to those skilled in the art through the present disclosure that various changes or modifications can be made to the present invention without departing from the principle and spirit scope of the present invention defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, rather than to limit the present invention, and the scope of protection is defined by the content of the claims.
