[0021] The following embodiments of the present disclosure are further described in detail with reference to the accompanying drawings and examples.

It should also be understood that terms defined in, for example, common dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an idealized or highly formal sense, unless explicitly defined as such herein.

[0027] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0028] See also Figure 1 and Figure 2 On the one hand, the present disclosure provides a photovoltaic frame adjustment mechanism, including a second bracket 2, the second bracket 2 is provided with a receiving groove 3, and the receiving groove 3 is provided with at least two limiting grooves 7 arranged along the first direction. The first bracket 1 is provided with a connecting portion accommodated in the receiving groove 3, and the connecting portion has the freedom to move along the first direction in the receiving groove 3. The connecting portion is formed with a limiting protrusion 6 that matches the limiting groove 7. The locking mechanism 4 is provided in the receiving groove 3 to hold the limiting protrusion 6 in the limiting groove 7. When the height of the photovoltaic frame needs to be adjusted, the locking mechanism 4 is adjusted to disengage the abutting connecting portion so that it can move in the receiving groove 3 along the first direction. The first direction is the depth direction of the receiving groove 3 ( Figure 1In the vertical direction), when the first bracket 1 is moved to the target position, the locking mechanism 4 is adjusted to abut and connect so that the limiting protrusion 6 is abutted in the limiting groove 7. Since at least two limiting grooves 7 arranged vertically are provided in the accommodating groove 3, the limiting protrusion 6 abuts in the limiting grooves 7 at different heights, thereby realizing the height adjustment between the first bracket 1 and the second bracket 2, thereby realizing the height adjustment of the accommodating space between the two. Therefore, the adjustment mechanism increases the number of photovoltaic modules that can be carried in a single transport, or reduces the overall thickness of the frame and increases the number of packages, which is beneficial to reducing transportation costs.

[0029] Regarding the limiting groove 7, it should be explained that each time the limiting protrusion 6 cooperates with a limiting groove 7 once, a position locking is completed. This locking is a position adjustment. There are at least two limiting grooves 7, which means that the connecting part can achieve at least two position adjustments.

[0030] In some embodiments, the connecting portion includes a first side panel 1-3 and a second side panel 1-4 arranged opposite to each other, and a limiting protrusion 6 is formed on the opposite sides of the first side panel 1-3 and the second side panel 1-4. The limiting protrusion 6 is located on the side where the first side panel 1-3 and the second side panel 1-4 contact the inner wall of the accommodating groove 3, thereby forming a double-sided limiting protrusion 6 and cooperating with the limiting grooves 7 corresponding to both sides, thereby ensuring the stability of the connecting portion between the first bracket 1 and the second bracket 2, avoiding the first side panel 1-3 or the second side panel 1-4 being subjected to a single force, resulting in the frame being skewed or twisted, which is beneficial for the adjustment mechanism to maintain stability and symmetry.

[0031] In some embodiments, an elastic spacing 5 is provided between the first side panel 1-3 and the second side panel 1-4 so as to adapt the first side panel 1-3 and the second side panel 1-4 to fit respectively with the inner wall surface of the accommodating groove 3. The first side panel 1-3 and the second side panel 1-4 are provided with an elastic structure or made of an elastic material. The elastic spacing 5 allows a distance to exist between the first side panel 1-3 and the second side panel 1-4 as compensation for deformation or displacement when subjected to force, thereby adapting to the need for movement of the connecting part and ensuring that when the movement stops, the limiting protrusion 6 and the limiting groove 7 can cooperate, and the first side panel 1-3 and the second side panel 1-4 can fit tightly against the inner wall of the accommodating groove 3, avoiding the gap being too large so that the first bracket 1 and the second bracket 2 do not fit properly and cause shaking, which is beneficial to improving the stability of the photovoltaic frame structure.

[0032] In some embodiments, a limiting protrusion 6 is formed at one end of the first side plate 1-3 and the second side plate 1-4 for inserting into the accommodating groove 3, and the first side plate 1-3 and the second side plate 1-4 are both formed with an elastic section for connecting the limiting protrusion 6. When the locking mechanism 4 can squeeze the first side plate 1-3 and the second side plate 1-4 to move in opposite directions, the limiting protrusions 6 of the two are abutted in the limiting groove 7 on the corresponding side. When the locking mechanism 4 releases the abutting state of the first side plate 1-3 and the second side plate 1-4, under the elastic action of the elastic section, the first side plate 1-3 and the second side plate 1-4 lean against each other under the action of the elastic force, and the limiting protrusions 6 of the two move out of the limiting groove 7, so that the connecting part of the first bracket 1 can move in the accommodating groove 3 along the first direction; and when the first side plate 1-3 and the second side plate 1-4 move in the accommodating groove 3, the limiting protrusion 6 is easier to embed into or exit the limiting groove 7, and the elastic section can absorb the stress when the first side plate 1-3 and the second side plate 1-4 move, reduce material fatigue, and help to extend the service life of the adjustment mechanism.

[0033] In some embodiments, the outer surface of the elastic segment is recessed inward to form a weakened portion 9. The weakened portion 9 causes the outer surface of the elastic segment to be recessed inward, reducing the material thickness, thereby making the elastic segment more susceptible to elastic deformation, which helps to limit the protrusion 6 from entering or exiting the limiting groove 7. The weakened portion 9 can disperse the stress generated by the elastic segment when subjected to force, reducing the elastic fatigue of the first side plate 1-3 and the second side plate 1-4, and extending the service life. The weakened portion 9 can reduce the space occupied by the elastic segment within the accommodating groove 3 when subjected to force, making the overall structure more compact, which helps to improve the space utilization of the photovoltaic module during transportation and storage.

[0034] In some embodiments, the locking mechanism 4 includes a supporting portion 4-1, a rod 4-2, and an operating portion 4-3 connected in sequence. The supporting portion 4-1 is located in the receiving groove 3. The end of the rod 4-2 away from the supporting portion 4-1 extends from the mounting hole 12 at the bottom of the receiving groove 3. A sealing ring or other sealing component is added around the mounting hole 12 to prevent moisture or dust from entering the receiving groove 3. The extended end of the rod 4-2 is connected to the operating portion 4-3. The operating portion 4-3 is used to drive the supporting portion 4-1 to move along the first direction so that the supporting portion 4-1 is located between the first side plate 1-3 and the second side plate 1-4, and is used to abut the limiting protrusion 6 in the limiting groove 7. The operating portion (4-3) allows the user to drive the supporting portion 4-1 by rotating or pushing and pulling to achieve the degree of freedom of locking or unlocking the connecting portion in the receiving groove 3. The length of the rod (4-2) is determined according to the distance that the supporting portion 4-1 needs to move along the first direction in the receiving groove (3), which is conducive to the height adjustment of the adjustment mechanism and improves work efficiency.

[0035] In some embodiments, the abutting portion 4-1 is in the shape of an elliptical cylinder. When the long axis direction of the abutting portion 4-1 points to the first side plate 1-3 and the second side plate 1-4 respectively, the abutting portion 4-1 can abut the limiting protrusion 6 in the limiting groove 7. When the short axis direction of the abutting portion 4-1 points to the first side plate 1-3 and the second side plate 1-4 respectively, the abutting portion 4-1 cannot abut the limiting protrusion 6 in the limiting groove 7. The operating portion 4-3 is used to drive the abutting portion 4-1 to rotate. The long axis of the holding portion 4-1 points to the first side panel 1-3 and the second side panel 1-4, and the connecting portion is locked and cannot move. By adjusting the direction of the operating portion 4-3, the short axis of the holding portion 4-1 points to the first side panel 1-3 and the second side panel 1-4. The length direction of the operating portion 4-3 corresponds to the long axis direction of the holding portion 4-1, and the width direction of the operating portion 4-3 corresponds to the short axis of the holding portion 4-1, which makes it easy for the user to control the holding portion 4-1 to press against or separate from the first side panel 1-3 and the second side panel 1-4.

[0036] In some embodiments, the operating part 4-3 is a rectangular plate, and the outer wall of the second bracket 2 corresponds to the protruding end of the rod 4-2 to form a rectangular groove 8 corresponding to the rectangular plate. The length direction of the rectangular plate corresponds to the long axis direction of the supporting part 4-1, and the width direction of the rectangular plate corresponds to the short axis direction of the supporting part 4-1. The movement of the supporting part 4-1 is driven by rotating the rectangular plate, and the state of the supporting part is accurately judged. The operation is more intuitive and convenient. The rectangular plate is placed in the rectangular groove 8 in a locked state with higher stability to avoid loosening due to external factors.

[0037] In some embodiments, the locking mechanism 4 also includes a cover plate 11, and the second bracket 2 is provided with a cover plate groove corresponding to the rectangular groove 8 for accommodating the cover plate 11, so that the rectangular plate is pressed into the rectangular groove 8, and a bolt locking mechanism is provided between the cover plate 11 and the cover plate groove. The operating part 4-3 is pressed into the rectangular groove 8 through the cover plate 11, and at the same time, the sealing performance can be improved to prevent dust, moisture, etc. from entering the rectangular groove 8 and the accommodating groove 3, thereby protecting the supporting part 4-1, the rod 4-2 and the operating part 4-3 from pollution and corrosion.

[0038] It should be noted that the first bracket 1 includes a first baffle 1-1 and a second baffle 1-2. The first baffle 1-1 and the second baffle 1-2 are arranged in parallel. The first side plate 1-3 and the second side plate 1-4 are connected to the second baffle 1-2 and are located on the side away from the first baffle 1-1, and are arranged perpendicular to the first baffle 1-1. Since the first baffle 1-1 and the second baffle 1-2 are used to encapsulate photovoltaic components, the first baffle 1-1 is provided with an anti-overflow protrusion 10. The anti-overflow protrusion 10 is located at the end of the first baffle 1-1, which effectively prevents the overflow of the colloid and reduces the occurrence of glue overflow. The first bracket 1 is made of metal material and the outer surface is provided with a corrosion-resistant composite layer. The corrosion-resistant composite layer is composed of a bottom layer, a middle layer and an outer layer arranged in sequence from the inside to the outside. The bottom layer is a phosphate film layer, the middle layer is an electrophoretic paint film layer, and the outer layer is a polyester paint film layer. The metal material is steel or an alloy material (such as an aluminum alloy); the outer surface is the surface of each component that can come into contact with the air.

[0039] In order to better understand the technical content of the present disclosure, the following description is given in combination with relatively preferred technical features.

The first bracket 1 is provided with a connecting portion accommodated in the receiving groove 3, and the connecting portion has the freedom to move along the first direction in the receiving groove 3. The connecting portion includes a first side plate 1-3 and a second side plate 1-4 arranged oppositely. The opposite sides of the first side plate 1-3 and the second side plate 1-4 are both formed with limiting protrusions 6, which cooperate with the limiting grooves 7. There is a connecting portion between the first side plate 1-3 and the second side plate 1-4. An elastic spacing 5 is provided to adapt the first side plate 1-3 and the second side plate 1-4 to fit respectively with the inner wall surface of the accommodating groove 3. A limiting protrusion 6 is formed on one end of the first side plate 1-3 and the second side plate 1-4 for inserting into the accommodating groove 3. The first side plate 1-3 and the second side plate 1-4 are both formed with an elastic section for connecting the limiting protrusion 6. The outer surface of the elastic section is recessed inward to form a weakened portion 9. The locking mechanism 4 includes a supporting portion 4-1, a rod 4-2 and an operating portion 4-3 connected in sequence. The supporting portion 4-1 is located in the accommodating groove 3, and one end of the rod 4-2 is away from the supporting portion 4-1. The rod 4-2 extends from the mounting hole 12 at the bottom of the accommodating groove 3, and the protruding end of the rod 4-2 is connected to the operating part 4-3. The operating part 4-3 is used to drive the abutting part 4-1 to move along the first direction so that the operating part 4-3 is located between the first side plate 1-3 and the second side plate 1-4, and is used to abut the limiting protrusion 6 in the limiting groove 7. The abutting part 4-1 is in the shape of an elliptical cylinder. When the long axis direction of the abutting part 4-1 points to the first side plate 1-3 and the second side plate 1-4 respectively, the abutting part 4-1 can abut the limiting protrusion 6 in the limiting groove 7. When the short axis direction points to the first side plate 1-3 and the second side plate 1-4 respectively, the supporting part 4-1 cannot support the limiting protrusion 6 in the limiting groove 7. The operating part 4-3 is used to drive the supporting part 4-1 to rotate. The operating part 4-3 is a rectangular plate. The outer wall of the second bracket 2 corresponds to the protruding end of the rod 4-2 to form a rectangular groove 8 corresponding to the rectangular plate. The locking mechanism 4 also includes a cover plate 11. The second bracket 2 is provided with a cover plate groove for accommodating the cover plate 11 corresponding to the rectangular groove 8, so as to press the rectangular plate into the rectangular groove 8. The cover plate 11 is connected to the cover plate groove by bolts.

[0041] The method of using the photovoltaic frame adjustment mechanism and its beneficial effects: when locked, the supporting portion 4-1 is located in the accommodating groove 3 and is in the shape of an elliptical cylinder. When the long axis direction of the supporting portion 4-1 points to the first side panel 1-3 and the second side panel (1-4) respectively, the supporting portion can support the limiting protrusion 6 in the limiting groove 7. The first side panel 1-3 and the second side panel 1-4 are fixed. One end of the rod 4-2 is connected to the supporting portion 4-1, and the other end extends through the mounting hole 12 at the bottom of the second bracket 2 and is connected to the operating portion 4-3. The operating portion 4-3 is a rectangular plate. When the connection part needs to be adjusted, the user opens the cover plate 11 by rotating the bolt on the cover plate 11. The user rotates the operating portion 4-3 manually or through a tool. The operating portion 4-3 drives the rod 4-2 to rotate, thereby bringing The movable supporting part 4-1 is rotated, and the supporting part 4-1 is rotated to its short axis direction pointing to the first side panel 1-3 and the second side panel 1-4 respectively, and the first bracket 1 is moved to the desired position. After moving to the target position, the user rotates the operating part 4-3 again to make the supporting part 4-1 return to the long axis direction pointing to the first side panel 1-3 and the second side panel 1-4 respectively, and the limiting protrusion 6 is abutted in the limiting groove 7. The first side panel 1-3 and the second side panel 1-4 are fixed, and the cover plate 11 is fixed in the cover plate groove by bolts to complete the locking. By matching the limiting protrusion with the limiting grooves at different positions in the first direction, the height of the photovoltaic frame can be adjusted, so that the photovoltaic modules can be stacked more compactly during transportation, and the number of photovoltaic modules carried at a single time is increased, which is conducive to reducing transportation costs.
