Description

Technical Field

[0001] This utility model relates to the field of battery cell assembly technology, and in particular to a reinforced structure for screw holes on the module frame. Background Technology

[0002] The module frame screw hole reinforcement structure is a support device for assembling solar cell modules. As the size of solar cells and module panels increases, the force that the screw holes on the frame must withstand also increases. As the demand for cost reduction continues to rise, the mounting hole surface of the frame is becoming thinner and thinner, and the distance from the hole to the edge is reduced from the original 12mm to 9mm (the hole diameter is 9mm) (the effective force-bearing area width at the edge is 4.5mm).

[0003] The frame itself has mechanical stress when the mounting holes are stamped. During installation, due to the 2-3mm wall thickness of the bracket, the area around the bolt holes in the frame will sink downwards during the pre-tightening process. (The outer edge of the frame mounting hole and the inner area of ​​the bracket mounting hole form a cantilever beam cavity structure. When the bolts are tightened downwards, the suspended area of ​​the frame hole sinks and deforms downwards). Assuming that the flat washer in contact with the frame is less than 0.8mm thick, the flat washer may also sink and deform at the same time. With the continuous development of technology, people have increasingly higher requirements for the manufacturing process of the screw hole reinforcement structure of the component frame.

[0004] Existing component frame screw hole positioning structures have certain drawbacks during use. The frame is under stress, and the risk of the frame holes being torn directly increases during gusts of wind, high wind pressure, or component shaking. After installation, the conventional frame surface (1.5-1.8mm wall thickness) undergoes metal fatigue under the action of gusts of wind, and the frame is at risk of being torn or broken after long-term installation, which has a certain adverse effect on the actual use. To address this, we propose a component frame screw hole reinforcement structure. Utility Model Content

[0005] Technical problem to be solved: In view of the shortcomings of the prior art, this utility model provides a component frame screw hole reinforcement structure, which thickens the C-side of the frame. From the perspective of the frame, the frame strength is enhanced. From the perspective of the component as a whole, the component is strengthened along with the frame reinforcement. After the component is installed on the bracket, the component frame may bend and deform under the influence of strong winds. However, the reinforced frame reduces the amount of deformation and reduces the risk of frame damage. This can effectively solve the problems in the background art.

[0011] Preferably, the reinforced C-surface has a vertically bent structure, an added edge sealing structure, and both the inner and outer sides are continuous flat surfaces.

[0012] Preferably, a first mounting bracket and a second mounting bracket are positioned between the reinforced D-side and the bracket. The first mounting bracket fits into the bracket, and the second mounting bracket fits into the reinforced D-side. A support frame is provided between the first mounting bracket and the second mounting bracket. A first positioning pin is positioned between the first mounting bracket and the bracket, and a second positioning pin is positioned between the second mounting bracket and the reinforced D-side.

[0013] Beneficial effects: Compared with the prior art, this utility model provides a component frame screw hole reinforcement structure, which has the following beneficial effects: This component frame screw hole reinforcement structure thickens the C-side of the frame. From the perspective of the frame, the frame strength is enhanced. From the perspective of the component as a whole, the component is strengthened along with the frame reinforcement.

[0023] like Figure 1-5 As shown, a component frame screw hole reinforcement structure includes a reinforced D-surface 1 and a bracket 10. The bottom of the reinforced D-surface 1 is integrally formed with a reinforced C-surface 5. The reinforced C-surface 5 is integrally formed with a hole C-surface reinforcing rib 3 and a conventional reinforcing rib 2. A chamfered reinforcement area 4 is provided at the corner between the reinforced D-surface 1 and the reinforced C-surface 5. A bolt 7 and a screw head 12 are positioned through the bracket 10, the conventional reinforcing rib 2, the hole C-surface reinforcing rib 3, and the reinforced C-surface 5. A nut 8 is screwed on the outer wall of the bolt 7. An upper flat washer 9 is positioned between the nut 8 and the conventional reinforcing rib 2. A lower flat washer 11 is positioned between the bracket 10 and the screw head 12. A laminate 6 is engaged and positioned at the top of the reinforced D-surface 1. The frame C-surface is thickened. From the perspective of the frame, the frame strength is enhanced. From the perspective of the component as a whole, the component is strengthened along with the frame reinforcement. After the component is installed on the bracket, the component frame may bend and deform under the influence of strong winds. However, the reinforced frame reduces the amount of deformation and reduces the risk of frame damage.

[0024] Furthermore, the reinforcement D-side 1, conventional reinforcing rib 2, chamfered reinforcing area 4, hole C-side reinforcing rib 3, and reinforced C-side 5 are integrally formed by casting.

[0025] Furthermore, surface C 5 is reinforced and fixed to bracket 10 by bolts 7, nuts 8, upper flat washers 9, lower flat washers 11 and screw heads 12.

[0026] Furthermore, the conventional reinforcing rib 2, the hole C-side reinforcing rib 3, and the reinforcing C-side 5 are reinforced into a square hollow tube structure, and a chamfered reinforcing area 4 is formed with the reinforcing D-side 1.

[0027] Furthermore, the reinforced C-surface 5 has a vertically bent structure with a flat section at both the top and bottom, which is divided into the hole C-surface reinforcing rib 3 and the conventional reinforcing rib 2.

[0028] Furthermore, surface C5 is enhanced with a vertically bent structure, an edge sealing structure, and both the inner and outer sides are entirely flat.

[0029] Furthermore, a first mounting bracket 13 and a second mounting bracket 14 are positioned between the reinforced D-side 1 and the bracket 10. The first mounting bracket 13 is attached to the bracket 10, and the second mounting bracket 14 is attached to the reinforced D-side 1. A support bracket 16 is provided between the first mounting bracket 13 and the second mounting bracket 14. A first positioning pin 15 is positioned between the first mounting bracket 13 and the bracket 10, and a second positioning pin 17 is positioned between the second mounting bracket 14 and the reinforced D-side 1. The first mounting bracket 13 and the second mounting bracket 14 are fixed to the bracket 10 and the reinforced D-side 1 respectively by the first positioning pin 15 and the second positioning pin 17, and are supported by the support bracket 16.

[0030] Working principle: This utility model includes a reinforced D-side 1, a conventional reinforcing rib 2, a hole-positioned C-side reinforcing rib 3, a chamfered reinforcing area 4, a reinforced C-side 5, a laminated component 6, a bolt 7, a nut 8, an upper flat washer 9, a bracket 10, a lower flat washer 11, a screw head 12, a first mounting bracket 13, a second mounting bracket 14, a first positioning pin 15, a support bracket 16, and a second positioning pin 17. The C-side of the frame is thickened, which strengthens the frame from the perspective of the frame itself. From the perspective of the entire component, the component is strengthened along with the reinforced frame. After the component is installed on the bracket, the frame of the component may bend and deform under the influence of strong winds, but the reinforced frame reduces the amount of deformation and reduces the risk of damage to the frame.

[0031] like Figure 1 As shown, the left side of the frame is the same as a regular frame, mainly in the structure of the right C-side. The area connecting to the D-side of the frame is a chamfered reinforcement area, no longer the original single-edge connection, but a reinforced square hollow tube structure with a rounded chamfer (generally recommended to be R1-R2mm). Then comes the installation area, which has a vertically bent structure with a flat section at both the top and bottom. This section is divided into hole reinforcement ribs and ordinary reinforcement ribs. The hole reinforcement ribs serve two purposes: 1. Vertical reinforcement to prevent the C-side from denting or bending; 2. Lateral limiting, with a 9mm spacing between the inner walls on both sides, exactly matching the width / diameter of the frame opening. Ordinary reinforcement ribs serve the first purpose and also reduce the risk of tearing.

[0032] like Figure 2 As shown, this figure is in Figure 1 An edge-sealing structure is added to the cross-section. The inner and outer sides (top and bottom) of surface C are a single flat section, with vertical reinforcing ribs in the middle. The overall structural strength of surface C is higher than that of surface C. Figure 1 ;

[0033] like Figure 3 The diagram shows the actual installation of bolt holes on-site. M8 bolts are used, passing through the bracket holes and the C-face of the frame. A flat washer is placed on the inside of the C-face of the frame, and finally, a nut is tightened. The bracket holes and the frame holes form a cross structure. Due to the thickened C-face design, the frame holes will not dent during bolt pre-tightening. The C-face of the frame resists the pressure from the mounting bolts thanks to its own deformation resistance.

[0034] like Figure 4 As shown, the main design structure and Figure 3 Similarly, when the component is subjected to dynamic wind pressure, the frame bends and sways along the support. The angle between the thickened C and D surfaces is less prone to stress, and under greater tension, the 90° angle will not open more than 90°. However, due to the up-and-down swaying, fatigue stress is generated around the holes in the frame. If the frame is too thin, it will be torn due to stress fatigue. The thickened frame will also experience stress, but the stress is reduced due to the reinforcement. The four reinforcing ribs from the mounting holes to the edge prevent the possibility of tearing.

[0035] Figure 3 and Figure 4 Both have thickened C-side bezels. From the perspective of the bezel, the bezel strength is enhanced. From the perspective of the component as a whole, the component is strengthened along with the reinforced bezel. After the component is installed on the bracket, it is affected by strong gusts of wind, and the component bezel bends and deforms. However, the reinforced bezel reduces the amount of deformation and reduces the risk of the bezel being damaged.
