Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaics, in particular to an angle code component, a packaging frame and a photovoltaic assembly. Background Art
[0002] In the photovoltaic industry, competition is increasing day by day, and cost reduction and efficiency improvement have become the main theme and permanent pursuit of the industry. As an important component of photovoltaic modules, the frame is responsible for the fixing, transportation, and bearing of the modules, and its cost accounts for about 10% of the module cost. At present, the packaging of photovoltaic modules generally adopts frame components. Traditional frame components have differentiated designs of long and short frames, which are mainly concentrated in the thickness of the B side of the frame, the width of the cavity, the width of the C side, and the thickness of the C side (see Figure 1). Since the two ends of the frame are cut at a 45° angle, the sum of the thickness of the B side of the long and short frames and the width of the cavity is consistent to ensure that there is no step at the assembly joint of the frame. At present, the combination of thickening the B side of the long frame and reducing the cavity width and thinning the B side of the short frame and increasing the cavity width is generally adopted. Generally, the thicker the wall thickness and the larger the cavity, the better the bearing capacity. However, the above combination has not been able to make the long frame obtain a greater load capacity, nor has it been able to further reduce the cost of the short frame. In addition, the current splicing and installation of the frame relies on the hard interference between the corner bracket teeth and the frame rivet points to generate the fastening force (see Figure 2). During long-term stress, due to uneven stress and wear on one side, the corner bracket and the frame will become loose, affecting the component load and service life. Utility Model Content

The corner bracket component of the utility model can improve the load capacity, reduce the frame cost, increase the fastening force between the corner bracket component and the frame, reduce or avoid the looseness between the corner bracket component and the frame, and improve the load and service life of the photovoltaic module.

[0035] The embodiment of the present application provides a corner bracket component 10 to solve the problem that the splicing and installation of the packaging frame of the photovoltaic module in the traditional technology relies on the hard interference between the corner bracket teeth and the frame rivet points to generate the fastening force, resulting in long-term uneven force and wear, causing the corner bracket and the frame to become loose, affecting the load and service life of the photovoltaic module. The corner bracket component 10 will be described below in conjunction with the accompanying drawings.
[0036] The angle code component 10 provided in the embodiment of the present application is exemplified as shown in Fig. 3, which is a schematic diagram of the structure of the angle code component 10 provided in the embodiment of the present application. The angle code component 10 of the present application can be used for photovoltaic module packaging.
[0037] In order to more clearly illustrate the structure of the angle code component 10, the angle code component 10 will be introduced below with reference to the accompanying drawings.
[0038] For example, please refer to Fig. 3, which is a schematic diagram of the structure of an angle bracket component 10 provided in an embodiment of the present application. An angle bracket component 10 includes a first clamping member 100 and a second clamping member 200.
[0039] The first clamping member 100 is connected to the second clamping member 200. The first clamping member 100 extends along the first direction. The second clamping member 200 extends along the second direction. There is an angle between the first direction and the second direction. It should be noted that the angle can be 0~90°. Please refer to FIG3 , the inner surface of the first clamping member 100 located inside the angle and the outer surface located outside the angle respectively have a limiter 300. The inner surface of the second clamping member 200 located inside the angle and the outer surface located outside the angle respectively have a limiter 300. The first clamping member 100 and the second clamping member 200 are respectively used to be clamped in the cavity of the frame 21.
[0040] The corner code component 10 of the present application is provided with stoppers 300 on the inner surface of the first clamping component 100 located inside the angle and the outer surface located outside the angle, and the stoppers 300 are provided on the inner surface of the second clamping component 200 located inside the angle and the outer surface located outside the angle, respectively, so that the first clamping component 100 and the second clamping component 200 can generate friction with the inner wall of the frame 21 on two surfaces respectively, thereby increasing the fastening force between the corner code component 10 and the frame 21, reducing or avoiding looseness between the corner code component 10 and the frame 21, and improving the component load and service life.
[0041] In some embodiments, the first direction and the second direction may be the same direction. In this case, the corner code component 10 is in a long strip structure as a whole, and the corner code component 10 may be used for linear splicing of two frames 21 distributed in the same direction.
[0042] In some embodiments, the first direction is perpendicular to the second direction, so that the angle between the first clamp 100 and the second clamp 200 is 90°. Generally speaking, the shape of the solar cell is a rectangular sheet as a whole, so the adjacent frames 21 are distributed at a vertical angle. Based on this, the angle between the first clamp 100 and the second clamp 200 is 90°, which is convenient for the packaging connection between the adjacent frames 21. In addition, the ends of the two adjacent frames 21 are cut into 45° inclined surfaces, as shown in Figures 7 and 8.

The length of the first clamping member 100 along the first direction and the length of the second clamping member 200 along the second direction can be set according to actual needs.
[0045] In some embodiments, the stopper 300 is a latching tooth.

The tip of the latching tooth on the second clamping member 200 faces the connection between the first clamping member 100 and the second clamping member 200. The latching tooth is arranged in the above direction, which can achieve the connection with the inner wall of the frame 21 to the greatest extent and increase the fastening force.
[0046] In some embodiments, a plurality of latch teeth are spaced apart and the spacing between adjacent latch teeth can be adjusted as required. For example, the spacing between adjacent latch teeth is 1 mm to 5 mm.
[0047] In some embodiments, the depth between adjacent latch teeth can be adjusted as needed, for example, the depth between adjacent latch teeth is 1 mm to 10 mm.
[0048] In some embodiments, the inner surface of the first clamping member 100 located in the included angle has a limiting groove 101. The limiting groove 101 is adjacent to the connection between the first clamping member 100 and the second clamping member 200 located in the included angle, and the limiting groove 101 is used for the end edge of the frame 21 that the second clamping member 200 cooperates with to be clamped, so that the two adjacent frames 21 can be ensured to be in a vertical splicing state.

[0050] In some of the embodiments, the thickness T1 of the B surface of the frame 21 that the first clamping member 100 cooperates with and the width W1 of the cavity can be set according to actual needs.
[0051] In some of the embodiments, the thickness T2 of the B surface of the frame 21 that the second clamping member 200 cooperates with and the width W2 of the cavity can be set according to actual needs.
[0052] In some embodiments, the first clamping member 100 has a cavity. At least one reinforcing rib 400 is disposed in the cavity of the first clamping member 100. In the present application, the reinforcing rib 400 disposed in the cavity of the first clamping member 100 can improve the structural strength of the first clamping member 100, improve the supporting strength of the corner code component 10 and the packaging frame 20, and improve the stability of the assembly.

The plurality of frames 21 are used to package solar cells, and adjacent frames 21 are fixedly connected by the corner code components 10.
[0056] In some embodiments, the frame 21 in the packaging frame 20 can be divided into a long frame and a short frame, and the long frame and the short frame can be adapted to different side lengths of solar cells. The specific lengths of the long frame and the short frame can be adaptively set according to actual needs.
