AI Technical Summary
The existing method of clamping the intermediate pressure plate in photovoltaic systems is difficult to guarantee the structural integrity of the assembly, especially since the horizontal displacement of the baffle affects the overall integrity of the assembly.
The design employs a middle pressure plate and a baffle. The baffle has upturned edges on both sides, with the component frame located between them. The middle pressure plate has a recessed fixing groove and an outward-turned edge. Fasteners pass through the middle pressure plate and are fixed to the support with the baffle. The component frame is also fixed by a limiting structure, enhancing the overall clamping effect.
By using a limiting structure and an overall clamping design, the overall robustness of the photovoltaic system assembly is significantly improved, resisting horizontal displacement of the baffle and enhancing the stability and strength of the assembly.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0025] like Figures 1 a to 1 e As shown, the intermediate pressing assembly of this utility model includes an intermediate pressing plate 100, a baffle 200, and fasteners 300.
[0026] The baffle 200 has upturned edges 201 on both sides for fixing the photovoltaic module frame 410, 420. The upturned edges 201 are supported between the two upturned edges 201 on the top surface of the baffle 200, and the upturned edges 201 form the bottom outer side stops of the module frame 410, 42.
[0027] The middle pressure plate 100 has a recessed fixing groove 110 and outward flanges 120 bent out on both sides. The component frames 410 and 420 are respectively located on both sides of the fixing groove 110. The component frames 410 and 420 are located between the outward flanges 120 and the baffle 200, clamping the component frames together vertically.
[0028] Fastener 300 passes through intermediate pressure plate 100 and baffle 200 in sequence and then fixes them to support member 500.
[0029] The bottom surface B of the baffle 200 is provided with an upward-facing first limiting structure that is embedded and fixed between the frames of each component and / or a downward-facing second limiting structure that is embedded and fixed to the support member 500.
[0030] like Figure 2In B-1, the first limiting structure uses a protrusion 210 formed by bending the middle of the baffle 200. The protrusion 210 faces upward and is precisely embedded in the middle of the bottom of the component frame 410, 420, forming a horizontal limit with the left and right upper flanges 201. At the same time, multiple bends form structural reinforcement. Figure 2 B-2, the second limiting structure is used to fit the support member 500, and is configured as a downwardly bent flange 220 formed by bending the two sides of the baffle 200 downwards for tightly fitting around the support member 500. The two downwardly bent flanges 220 are fastened to the outer wall of the support member 500 to achieve relative fixation. For example... Figure 2 B-3, the second limiting structure may also include a groove 230 formed by the recessed bottom of the baffle 200 for tight fitting into the support 500.
[0031] Based on the overall force-bearing structure formed by the upper and lower clamping of the baffle and the intermediate pressure plate, the baffle is embedded and fixed between the frame of each component with its upper face facing up and / or embedded and fixed to the support component with its lower face facing down, thereby realizing the horizontal displacement limit of the baffle. Compared with the existing photovoltaic module installation structure, it can further enhance the overall robustness of the assembly.
[0032] In an optional embodiment, through holes for fasteners 300 to pass through are provided in the fixing groove 110 of the intermediate pressure plate 100 and on the first limiting structure of the baffle 200. Figure 3 and Figure 4 As shown, the through hole is a round hole, a horizontal elongated hole, or a vertical elongated hole. Fastener 300 passes through the middle of the component frame 410 and 420 to balance the left and right clamping forces.
[0033] In one alternative embodiment, such as Figure 5 In A1A2-1, the edge of the upper flange 201 is bent inward to form an inner flange, which serves as a hook to hold the outer support of the component frame, or, as... Figure 5 In A1A2-2, the upper flange 201 forms a 90° angle with the baffle 200, or, as... Figure 5 In A1A2-3, the upper flange 201 forms a 45° angle with the baffle 200.
[0034] In an optional embodiment, the outer flange 120 of the intermediate pressure plate 100 has anti-slip surfaces A1 and A2 for pressing the component frame, such as... Figure 6 The shot peening anti-slip method described in A1A2-1, or, as Figure 6 The toothed anti-slip surface shown in A1A2-2, or, as... Figure 6 The textured anti-slip surface shown in A1A2-3.
[0035] In an optional embodiment, to avoid scratching the edge clamping surface, such as Figure 7 For A1A2-4, the edges of the outward-facing flange are rounded for protection, or, as... Figure 7For A1A2-5, the outer edge should be protected with a slope, or, as... Figure 7 A1A2-6, outer edge corner bending protection to avoid air gaps.
[0036] In an optional embodiment, the intermediate pressure plate 100 is provided with structural reinforcements to enhance the rigidity and strength of the parts. The structural reinforcements may include reinforcing structures located on the recessed sides B1 and B2 of the intermediate pressure plate 100, such as... Figure 8 The downward-pressing stiffeners shown in B1 and B2-1, such as Figure 8 The triangular reinforcing ribs shown in B1 and B2-2, such as Figure 8 The louvered reinforcing ribs shown in B1 and B2-3, and the reinforcing structure located on the bottom surface C of the intermediate pressure plate 100, as shown in B1 and B2-3, are examples of this. Figure 9 The bent reinforcing rib shown in C-1, such as Figure 9 The raised reinforcing rib shown in C-2, such as Figure 9 The boss reinforcing rib shown in C-3, and the various combinations mentioned above.
[0037] This utility model also provides a photovoltaic system in which the above-mentioned intermediate pressing assembly is used to install the two side frames.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
