Figure 3 This application illustrates an explosion of a border block according to an embodiment of the present application.

[0036] To address the aforementioned issues, this application provides a photovoltaic frame for mounting photovoltaic laminates. The photovoltaic frame includes multiple frame blocks 1 and multiple adjustment components 3. Two adjacent frame blocks 1 are connected by an adjustment component 3, and the adjustment component 3 is used to adjust the spacing between two adjacent frame blocks 1. The multiple frame blocks 1 are sequentially connected by the multiple adjustment components 3 to form a mounting cavity 2 for mounting photovoltaic laminates.

[0037] It should be understood that multiple frame blocks 1 are sequentially connected by multiple adjusting components 3 to form a mounting cavity 2 for mounting photovoltaic laminates. Since the photovoltaic laminates are typically rectangular, the mounting cavity 2 is also typically rectangular. The multiple frame blocks 1 can be arranged in two ways: one is in a long strip shape, which can form the four sides of the mounting cavity 2; the other is in an angled arrangement with an angle of 90°, which can form the angle of the mounting cavity 2.

[0038] Reference Figure 1 , Figure 2 as well as Figure 5 An adjustment component 3 is provided between two adjacent frame blocks 1, meaning that the number of adjustment components 3 is equal to the number of frame blocks 1. The adjustment component 3 can be used to adjust the spacing between two adjacent frame blocks 1. By setting multiple frame blocks 1 and multiple adjustment components 3, this application can adjust the size of the photovoltaic frame according to the size of the photovoltaic laminate, eliminating the need to repurchase frames of different sizes, reducing inventory, and thus reducing costs.

[0039] In some optional embodiments, each frame block 1 is provided with two sliding blocks 4 at intervals; the adjustment component 3 includes an adjustment plate 31 and a driving mechanism, the adjustment plate 31 is provided with a sliding hole 311; the sliding blocks 4 of two adjacent frame blocks 1 that are close to each other extend into the same sliding hole 311; the driving mechanism is used to drive the sliding blocks 4 to move the frame blocks 1, so as to realize the adjustment of the interval between two adjacent frame blocks 1.

[0040] A border block 1 is also provided with two sliding blocks 4. The connection between the sliding blocks 4 and the border block 1 can be a fixed connection or a detachable connection. This application does not impose any restrictions. The two sliding blocks 4 are arranged at intervals along the extension direction of the border block 1. In one example, one sliding block 4 is located at one end of the border block 1 and the other sliding block 4 is located at the other end of the border block 1.

[0041] The adjustment assembly 3 includes an adjustment plate 31 and a drive mechanism. The adjustment plate 31 is elongated and has a sliding hole 311 extending along its length. The adjustment plate 31 corresponds to two adjacent frame blocks 1. Sliding blocks 4 of the adjacent frame blocks 1, positioned close to each other, extend into the sliding hole 311 of the adjustment plate 31. The sliding blocks 4 slide within the sliding hole 311, thereby changing the distance between the two adjacent frame blocks 1 and thus adjusting the size of the mounting cavity 2. To facilitate the sliding of the sliding blocks 4 within the sliding hole 311, the sliding blocks 4 are cylindrical in shape.

[0042] The drive mechanism can drive two sliding blocks 4 located in the same sliding hole 311 to change the distance between the two sliding blocks 4. When it is necessary to increase the size of the mounting cavity 2, the drive mechanism drives the two sliding blocks 4 located in the same sliding hole 311 to move away from each other. When it is necessary to decrease the size of the mounting cavity 2, the drive mechanism drives the sliding blocks 4 located in the same sliding hole 311 to move closer to each other.

[0043] In some optional embodiments, the drive mechanism includes an adjusting seat 32, a screw 33, and a drive member 34. The two adjusting seats 32 are connected one-to-one with the two sliding blocks 4 in the same sliding hole 311. Both adjusting seats 32 are provided with threaded holes. The screw 33 is provided with a first section of thread and a second section of thread with opposite threads. One adjusting seat 32 is threadedly connected to the first section of thread, and the other adjusting seat 32 is threadedly connected to the second section of thread. The drive member 34 is connected to the adjusting plate 31, and the output end of the drive member 34 is connected to the screw 33.

[0044] The drive mechanism includes two adjusting seats 32, which are respectively connected to two sliding blocks 4. The connection method can be a fixed connection or a detachable connection. In one example, the adjusting seats 32 and the sliding blocks 4 are connected by bolts. When the adjusting seats 32 move, they can drive the sliding blocks 4 to move. Both adjusting seats 32 are provided with threaded holes.

[0045] The drive mechanism also includes a screw 33 and a drive element 34. The screw 33 is threadedly connected to the threaded hole of the adjusting seat 32. The screw 33 includes two threaded sections, namely a first thread and a second thread, with the helical directions of the first and second threads being opposite. One adjusting seat 32 is connected to the first thread, and the other adjusting seat 32 is connected to the second thread. When the screw 33 rotates, the two adjusting seats 32 move closer to or further away from each other. The drive element 34 can be a motor or a handle; this application does not impose any restrictions. When the drive element 34 is a motor, the motor model can be selected according to the actual situation. In one example, the motor is a servo motor. The output end of the drive element 34 is connected to the screw 33, that is, the drive element 34 can be used to drive the screw 33 to rotate.

[0046] During adjustment, the size of the photovoltaic laminate can be adjusted according to its dimensions. When the size of the photovoltaic frame needs to be increased, the drive unit 34 is activated, causing the screw 33 to rotate in a first direction. This rotation moves the two adjusting seats 32 away from each other, which in turn moves the two sliding blocks 4 away from each other, thus increasing the size of the photovoltaic frame. When the size of the photovoltaic frame needs to be decreased, the drive screw 33 rotates in a second direction, bringing the two adjacent frame blocks 1 closer together, thereby decreasing the size of the photovoltaic frame. The first and second directions are opposite; when either direction is clockwise, the other is counterclockwise.

[0047] Reference Figure 1 and Figure 5 In some optional embodiments, the adjusting plate 31 has a "U"-shaped cross-section, the frame block 1 is located in the inner cavity of the adjusting plate 31, and the sliding hole 311 is located above the adjusting plate 31. The adjusting plate 31 wraps around the frame block 1, thereby improving the stability of the installation between the frame block 1 and the adjusting plate 31. A second mounting hole may also be provided below the adjusting plate 31, extending along the length of the adjusting plate 31 and communicating with the first mounting hole, so as to facilitate the installation of the frame block 1 on other components.

[0048] The sliding hole 311 can be located above, on the side wall or below the adjusting plate 31. This application does not impose any restrictions, but when the sliding hole 311 is located above the adjusting plate 31, it can further improve the convenience of operation for the operator.

[0049] Reference Figure 3 and Figure 4 In some optional embodiments, the frame block 1 is provided with a snap-fit ​​groove 11 for assembling photovoltaic laminates on the side facing the mounting cavity 2. The snap-fit ​​groove 11 has a "U" shaped cross section, that is, the snap-fit ​​groove 11 has an upper top surface, a side wall, and a lower bottom surface. The snap-fit ​​groove 11 extends along the extension direction of the frame block 1, and the side of the photovoltaic laminate extends into the snap-fit ​​groove 11, thereby assembling the photovoltaic laminate with the photovoltaic frame.

[0050] In some optional embodiments, a flexible pad 12 is provided within the snap-fit ​​groove 11. The flexible pad 12 includes an upper wall 121, a side wall 122, and a lower wall 123. The upper wall 121 is fitted to the top surface of the snap-fit ​​groove 11, and the lower wall 123 is fitted to the bottom surface of the snap-fit ​​groove 11. The side wall 122 is used to connect the upper wall 121 and the lower wall 123. The flexible pad 12 can be made of flexible materials such as polyurethane composite material. The flexible pad 12 has an integrally formed upper wall 121, side wall 122, and lower wall 123. The upper wall 121, side wall 122, and lower wall 123 can be used to wrap the sides of the photovoltaic laminate. During installation, it can provide cushioning for the photovoltaic laminate, protect the photovoltaic laminate, and reduce the occurrence of breakage of the photovoltaic laminate. In addition, the flexible pad 12 can deform, improving the tightness of the connection between the photovoltaic laminate and the frame block 1.

[0051] In some optional embodiments, the sidewall of the snap-fit ​​groove 11 is further provided with a positioning block 111, and the upper wall 121, sidewall 122 and lower wall 123 are surrounded by a positioning groove 124 for snapping the positioning block 111 on the side opposite to the mounting cavity 2. The positioning block 111 is elongated and extends along the extension direction of the snap-fit ​​groove 11. The material of the positioning block 111 is the same as that of the frame block 1. The positioning block 111 and the frame block 1 are integrally formed. The positioning groove 124 of the flexible pad 12 snaps into the positioning block 111, which can improve the stability of the connection between the flexible pad 12 and the frame block 1.

[0052] In some optional embodiments, at least two positioning blocks 111 are provided and spaced apart along the height direction of the snap-fit ​​groove 11. An installation groove 112 is formed between two adjacent positioning blocks 111, and an adhesive strip 13 for connecting the flexible pad 12 is provided in the installation groove 112. In one example, two positioning blocks 111 are provided and spaced apart along the height direction of the snap-fit ​​groove 11. The upper positioning block 111 is attached to the upper top surface of the positioning groove 124, and the lower positioning block 111 is attached to the lower bottom surface of the positioning groove 124, thereby realizing the snap-fit ​​between the positioning block 111 and the positioning groove 124. An installation groove 112 is formed between the two positioning blocks 111, and the adhesive strip 13 is located between the installation grooves 112. The adhesive strip 13 can connect the frame block 1 and the flexible pad 12, improving the stability of the installation between the flexible pad 12 and the adhesive strip 13.

[0053] In some optional embodiments, the frame block 1 is further provided with a weight-reducing cavity 14, which extends along the extending direction of the frame block 1 and is located below the snap-fit ​​groove 11. This application does not limit the shape of the weight-reducing cavity 14; its cross-section can be rectangular, triangular, or any other arbitrary shape. The weight-reducing cavity 14 reduces the weight of the frame block 1, facilitating handling, and also reduces the material usage of the frame block 1, saving costs.

[0054] In some optional embodiments, a reinforcing rib 141 is provided inside the weight-reducing cavity 14, and the reinforcing rib 141 extends along the extending direction of the weight-reducing cavity 14. The material of the reinforcing rib 141 is the same as that of the frame block 1, and the reinforcing rib 141 is integrally formed with the frame block 1. The reinforcing rib 141 is elongated, and the provision of the reinforcing rib 141 can improve the strength of the frame block 1.

[0055] In some optional embodiments, two reinforcing ribs 141 are provided, one located on the upper top surface of the weight-reducing cavity 14 and the other located on the lower bottom surface of the weight-reducing cavity 14. The provision of two reinforcing ribs 141 can further improve the strength of the frame block 1.

[0056] In some optional embodiments, a weight-reducing groove 15 is provided on the side of the frame block 1 facing away from the mounting cavity 2. Multiple weight-reducing grooves 15 are provided and arranged at intervals along the height direction of the frame block 1. The weight-reducing grooves 15 extend along the extension direction of the frame block 1. The provision of the weight-reducing grooves 15 can further reduce the weight of the frame block 1 and reduce the material used in the frame block 1.

[0057] Reference Figure 3 In some optional embodiments, a self-cleaning coating 16 is provided on the side of the frame block 1 facing away from the mounting cavity 2. The self-cleaning coating 16 is a nanomaterial, and the self-cleaning coating 16 can reduce the adhesion of dust and dirt on the surface of the weight reduction groove 15, maintain the aesthetics and cleanliness of the photovoltaic frame, and reduce maintenance costs.

[0058] In some optional embodiments, a protrusion 17 extends from the end of the frame block 1 away from the snap-fit ​​groove 11 toward the mounting cavity 2. The protrusion 17 is made of the same material as the snap-fit ​​groove 11, and the protrusion 17 is integrally formed with the frame block 1, extending along the extending direction of the frame block 1. The protrusion 17 is provided with a first mounting hole, which can be used to mount the frame block 1 to other components.
