[0030] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0031] The following is for reference. Figures 1-2 The frame 100 of the photovoltaic module according to an embodiment of the present utility model is described.

[0032] Reference Figures 1-2 As shown, the frame 100 of the photovoltaic module according to the first aspect embodiment of the present invention includes: an outer frame 10 and an inner frame 20. The outer frame 10 includes an outer frame body 11 and a first engagement structure 12. The first engagement structure 12 is connected to one end of the outer frame body 11 and is bent upward relative to the outer frame body 11. The first engagement structure 12 forms an engagement groove 121. The inner frame 20 is disposed inside the outer frame 10 and is integrally formed with the outer frame 10. The inner frame 20 includes an inner frame body 21, a first support portion 22 and a first engagement portion 23. One end of the inner frame body 21 is connected to the outer frame body 10. The other end of the frame body 11 is connected to and bent relative to the outer frame body 11. The inner frame body 21 has a mounting groove 24 for mounting photovoltaic cells. One end of the first support part 22 is connected to the other end of the inner frame body 21 and is bent relative to the inner frame body 21. The first engagement part 23 is connected to the other end of the first support part 22 and is bent upward in a straight line relative to the first support part 22. The first engagement part 23 is disposed in the engagement groove 121. The first engagement structure 12 and the first engagement part 23 form at least a three-layer stacked structure 30.

[0033] Specifically, the bottom of the frame of traditional photovoltaic modules has poor bending and torsional resistance. Under long-term stress, the bottom of the frame is prone to deformation, which affects the overall structural stability of the photovoltaic module. Moreover, the deformation of the frame will also cause the glass panel of the photovoltaic module to be under pressure, increasing the risk of cracking or damage, and thus affecting the power generation efficiency.

[0034] Therefore, the frame 100 of the photovoltaic module needs to be optimized. The frame 100 of the photovoltaic module is mainly composed of an outer frame 10 and an inner frame 20. The first interlocking structure 12 in the outer frame 10 is bent upward relative to the outer frame body 11, which can increase the bending and compressive strength of the first interlocking structure 12 relative to the outer frame body 11.

[0035] Furthermore, the inner frame 20 and the outer frame 10 are integrally formed, with the inner frame 20 folded relative to the outer frame 10, and a portion of the inner frame 20 fitting against the outer frame 10. This creates a multi-layered structure, thereby improving the overall strength of the frame 100. The mounting groove 24 is U-shaped, which facilitates the installation of photovoltaic panels.

[0036] Furthermore, the first support portion 22 is bent relative to the inner frame body 21, which increases the support strength of the first support portion 22. The first engagement portion 23 is bent upward in a straight line relative to the first support portion 22, so that the first engagement portion 23, the first support portion 22, and the inner frame 20 together form a U-shaped cavity. When the bottom of the frame 100 is impacted by an external force, the U-shaped cavity can play an energy-absorbing and buffering role, thereby increasing the bending and torsional resistance of the frame 100.

[0037] Alternatively, multiple reinforcing posts can be provided between the first engaging part 23 and the inner frame 20. The multiple reinforcing posts are spaced apart along the length direction of the first engaging part 23. In this way, deformation between the first engaging part 23 and the inner frame 20 can be prevented, thereby improving the strength between the first engaging part 23 and the inner frame 20.

[0038] Alternatively, a reinforcing plate can be provided between the first engaging part 23 and the inner frame 20, which can also improve the strength between the first engaging part 23 and the inner frame 20.

[0039] Furthermore, the first engaging portion 23, which bends upwards in a straight line, is disposed within the engaging groove 121 formed by the first engaging structure 12. This not only protects the first engaging portion 23 but also prevents it from bending and deforming. Additionally, the first engaging structure 12 and the first engaging portion 23 form at least a three-layer stacked structure 30, which increases the contact area between the first engaging portion 23 and the first engaging structure 12. This reduces stress and improves the bending and torsional strength of the frame 100, further enhancing the overall strength of the frame 100.

[0040] Therefore, the first engagement portion 23 in the frame 100 of the photovoltaic module is bent upward in a straight line relative to the first support portion 22, which can play the role of energy absorption and buffering. Moreover, the first engagement structure 12 is bent upward relative to the outer frame body 11, and the first engagement portion 23 is located in the engagement groove 121, which can increase the contact area between the first engagement portion 23 and the first engagement structure 12, reduce the stress, and thus improve the bending and torsional strength of the frame 100.

[0041] According to specific embodiments of this utility model, such as Figure 1 As shown, the angle at which the first engaging part 23 is bent upward relative to the first supporting part 22 is α, satisfying the relationship: 80°≤α≤100°.

[0042] Specifically, the angle α at which the first engaging part 23 is bent upward relative to the first supporting part 22 can be set to 80°, 90° and 100°. When the angle α at which the first engaging part 23 is bent upward in a straight line relative to the first supporting part 22 is set to 90°, this not only ensures the strength of the bottom of the frame 100, but also makes the bottom of the frame 100 more evenly stressed, thereby preventing the first engaging part 23 from deforming.

[0043] Furthermore, when the angle α of the first engagement part 23 being bent upward in a straight line relative to the first support part 22 is set to 90°, a U-shaped groove can be formed between the first engagement part 23, the first support part 22, and the inner frame 20, thereby increasing the strength against deformation and also collecting rainwater at the bottom of the frame 100, thus facilitating drainage at the bottom of the frame 100.

[0044] According to some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the first occlusal structure 12 includes a second occlusal portion 122 and a third occlusal portion 123. One end of the second occlusal portion 122 is bent upwards in a straight line relative to the outer frame body 11, and the other end of the second occlusal portion 122 is connected to the third occlusal portion 123. The third occlusal portion 123 is bent downwards in a straight line relative to the second occlusal portion 122. The second occlusal portion 122 and the third occlusal portion 123 form an occlusal groove 121. The first occlusal portion 123, the second occlusal portion 122 and the third occlusal portion 123 form a three-layer stacked structure 30.

[0045] The first occlusal structure 12 is mainly composed of a second occlusal part 122 and a third occlusal part 123. In order to wrap the first occlusal part 23, one end of the second occlusal part 122 is bent upward in a straight line relative to the outer frame body 11, and the third occlusal part 123 is bent downward in a straight line relative to the second occlusal part 122. This allows an occlusal groove 121 to be formed between the second occlusal part 122 and the third occlusal part 123, which facilitates the first occlusal part 23 to extend into the occlusal groove 121. This can protect the first occlusal part 23 and prevent it from deforming.

[0046] Furthermore, the first occlusal portion 23, the second occlusal portion 122, and the third occlusal portion 123 form a three-layer stacked structure 30, with the first occlusal portion 23, the second occlusal portion 122, and the third occlusal portion 123 fitting together surface to surface. This increases the structural strength of the first occlusal portion 23, the second occlusal portion 122, and the third occlusal portion 123, thereby improving the overall strength of the first occlusal portion 23, the second occlusal portion 122, and the third occlusal portion 123.

[0047] According to some embodiments of this utility model, such as Figure 1As shown, the width of the upward bend of the second engagement part 122 is L1, and the distance from the bottom wall of the mounting groove 24 to the bottom of the outer frame 10 is L2. The relationship between L1 and L2 is: 0.25L2≤L1≤0.3L2.

[0048] The distance L2 from the bottom wall of the mounting groove 24 to the bottom of the outer frame 10 can be 3 or 4 times the width L1 of the upward bending of the second biting part 122. The width is the height in the vertical direction. This can shorten the distance from the bottom wall of the mounting groove 24 to the top of the second biting part 122. In this way, the width of both the second biting part 122 and the third biting part 123 can be increased by a certain amount, thereby improving the strength of the first biting structure 12 and preventing the first biting structure 12 from deforming.

[0049] According to some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the outer frame body 11 includes: a first top plate 101, a first side plate 102 and a first bottom plate 103. The first side plate 102 is bent and connected between the first top plate 101 and the first bottom plate 103. The first bottom plate 103 and the first support part 22 are surface-to-surface to form a two-layer stacked structure.

[0050] The first side plate 102 is located between the first top plate 101 and the first bottom plate 103, and can provide support for the first top plate 101 and the first bottom plate 103. In addition, the first bottom plate 103 and the first support part 22 are surface-to-surface to form a two-layer stacked structure, which can not only increase the contact area and reduce stress concentration, but also improve the strength and rigidity of the first bottom plate 103 and the first support part 22, thereby preventing cracks from forming.

[0051] Furthermore, the first top plate 101 is tilted downwards at an angle of no more than 15 degrees relative to the horizontal plane. This part is used to block excess silicone from overflowing, which can also reduce the need for cleaning the front of the photovoltaic module and reduce labor costs.

[0052] According to some embodiments of this utility model, such as Figure 2 As shown, the first engagement portion 23 and the third engagement portion 123 are welded together, and / or the first support portion 22 is welded together with the first base plate 103.

[0053] The first occlusal portion 23, the third occlusal portion 123, and the second occlusal portion 122 are first pressed together by mechanical equipment to ensure a full fit. Furthermore, the first occlusal portion 23 and the third occlusal portion 123 are connected by welding, thereby making the connection between the first occlusal portion 23 and the third occlusal portion 123 more stable and secure. The first occlusal portion 23 can also be connected to the second occlusal portion 122 by welding, thereby making the connection between the first occlusal portion 23 and the second occlusal portion 122 more stable and secure.

[0054] Furthermore, the first support part 22 is welded to the first base plate 103, which makes the connection between the first support part 22 and the first base plate 103 more stable and firm.

[0055] Alternatively, the first occlusal portion 23, the third occlusal portion 123, and the second occlusal portion 122 can be riveted together by mechanical equipment, thereby improving the stability of the connection between the first occlusal portion 23, the third occlusal portion 123, and the second occlusal portion 122.

[0056] According to a specific embodiment of the present invention, the weld point between the first engagement portion 23 and the third engagement portion 123 is located in the middle region of the width direction of the third engagement portion 123, and / or the weld point of the first support portion 22 and the portion of the first base plate 103 corresponding to the first support portion 22 is located in the middle region of the width direction of the first support portion 22.

[0057] Multiple welding points are provided between the first biting part 23 and the third biting part 123. All welding points are located in the middle area of ​​the width direction of the third biting part 123, so that the welding between the first biting part 23 and the third biting part 123 can be more secure.

[0058] Alternatively, multiple welding points may be provided on the portion of the first support 22 and the portion of the first base plate 103 corresponding to the first support 22. These multiple welding points are located in the middle region of the width direction of the first support 22, thereby making the welding of the portion of the first support 22 and the portion of the first base plate 103 corresponding to the first support 22 more secure.

[0059] According to some embodiments of the present invention, the inner frame body 21 includes: a mounting part 25 and a connecting part 26. The mounting part 25 is connected to the first top plate 101, and the mounting part 25 is bent relative to the first top plate 101. The mounting part 25 forms a mounting groove 24. The connecting part 26 is bent and connected between the mounting part 25 and the first support part 22. The connecting part 26 abuts against the first bottom plate 103.

[0060] The inner frame body 21 is mainly composed of a mounting part 25 and a connecting part 26. The mounting groove 24 formed by the mounting part 25 facilitates the installation and fixing of the photovoltaic cells. In addition, the connecting part 26 is located between the mounting part 25 and the first support part 22, thereby providing support for the connection between the mounting part 25 and the first support part 22.

[0061] According to some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the connecting part 26 is spaced apart from the first side plate 102. A cavity is formed between the first side plate 102, the first bottom plate 103, the mounting part 25, and the support part. The cavity is used to install corner brackets, and / or the mounting part 25 includes: a second top plate 251, a second side plate 252, and a second bottom plate 253. The second top plate 251 is connected to one end of the first top plate 101, and the second top plate 251 is bent relative to the first top plate 101. One end of the second side plate 252 is connected to the first top plate. At the other end of 101, the second side plate 252 is bent relative to the first top plate 101.
