[0038] Referring to Figures 1, 2 and 3, Figure 1 is a schematic diagram of a photovoltaic module connection structure provided by an embodiment of the present invention. Figure 2 is a schematic diagram of a photovoltaic module connection structure provided by an embodiment of the present invention in cooperation with a photovoltaic module and a purlin. Figure 3 is a front view of a photovoltaic module connection structure provided by an embodiment of the present invention in cooperation with a photovoltaic module and a purlin. The photovoltaic module connection structure provided by an embodiment of the present invention includes a pressing piece 100, a driving piece 200 and a deforming piece 300; the pressing piece 100 is used for crimping on a photovoltaic module 500; the driving piece 200 is connected to the pressing piece 100; the deforming piece 300 is connected to the driving piece 200, and a locking portion 310 is provided at one end of the deforming piece away from the pressing piece 100, and the locking portion 310 is used to extend into a groove 410 of a purlin 400, and the driving piece 200 is used to drive the deforming piece 300 to deform so that the locking portion 310 opens for locking with the purlin 400.

[0039] Specifically, the present application first places the photovoltaic component 500 on the purlin 400, and then extends the locking portion 310 into the groove 410 of the purlin 400, and makes the compression piece 100 abut against the photovoltaic component 500, and controls the driving member 200 to drive the deforming member 300 to deform, so that the locking portion 310 opens and locks with the purlin 400, so as to fix the compression piece 100 on the purlin 400, so that the compression piece 100 can cooperate with the purlin 400 to clamp the photovoltaic component 500, thereby realizing the installation of the photovoltaic component 500. That is, in the present application, it is only necessary to control the driving member 200 to drive the deforming member 300 to deform, so as to realize the installation of the photovoltaic component 500, thereby improving the convenience and efficiency of installing the photovoltaic component 500 by the photovoltaic component connection structure.

[0040] Referring to Figures 1, 3 and 4, Figure 4 is a schematic diagram of a deformable member in a photovoltaic module connection structure provided by an embodiment of the utility model. In one embodiment, the deformable member 300 further includes a connecting portion 320 and two bending portions 330, the two bending portions 330 are respectively connected to the two ends of the connecting portion 320 to enclose a matching groove 340, and the two bending portions 330 are provided with a locking portion 310 on the opposite sides; the driving member 200 is penetrated through the connecting portion 320 and abuts against the opposite side of the two bending portions 330, and the driving member 200 partially extends outside the matching groove 340 to support the deformable member 300, and the driving member 200 is configured to move relative to the groove wall of the matching groove 340 to open the bending portion 330.

[0041] Specifically, the bending portion 330 is connected to the side of the connecting portion 320 away from the pressing piece 100, and the driving member 200 partially extends into the groove 410 of the purlin 400 through the notch of the matching groove 340, and abuts against the side of the bending portion 330 away from the pressing piece 100, thereby supporting the deformable member 300 and limiting the deformable member 300 from escaping relative to the driving member 200, so that the pressing piece 100, the deformable member 300 and the driving member 200 can be pre-installed to form an assembly. Compared with the operation in the prior art that requires the nut to be sleeved on the screw from the side of the purlin 400 away from the photovoltaic component 500, the installation steps are reduced and the convenience and efficiency of the installation are improved.

[0042] Among them, since the photovoltaic component connection structure is easy to operate, the photovoltaic component connection structure can be grabbed by a robot for installation, and then the driving member 200 is controlled to rotate by the robot to achieve automated installation of the photovoltaic component 500, thereby reducing installation costs.

[0043] Referring to Figures 1, 2, 3, 4 and 5, Figure 5 is a schematic diagram of a driving block in a photovoltaic module connection structure provided by an embodiment of the utility model. In one embodiment, the driving member 200 includes a driving rod 210 and a driving block 220, the driving block 220 is used to abut against the side of the bending portion 330 away from the pressing member 100, the driving rod 210 is penetrated through the connecting portion 320, and extends into the matching groove 340 to be threadedly connected with the driving block 220, and the driving rod 210 is configured to rotate around its own axis to move relative to the driving block 220, so as to push the two bending portions 330 relatively away from each other.

[0044] Specifically, the driving rod 210 is inserted into the pressing piece 100, and the driving block 220 is in contact with the side of the two bending portions 330 away from the pressing piece 100, so that when the driving rod 210 rotates around its own axis, the rotation of the driving block 220 is restricted, so that the driving rod 210 and the driving block 220 can move relative to each other. The driving rod 210 or the driving block 220 is in contact with the opposite side of the two bending portions 330, and through the relative movement of the driving rod 210 and the driving block 220, the driving rod 210 or the driving block 220 can push the two bending portions 330 relatively away from each other, thereby realizing the opening of the bending portions 330.

[0045] Referring to Figures 1, 6 and 7, Figure 6 is a first cross-sectional view of the photovoltaic module connection structure provided in one embodiment of the utility model, in cooperation with the photovoltaic module and the purlin. Figure 7 is a second cross-sectional view of the photovoltaic module connection structure provided in one embodiment of the utility model, in cooperation with the photovoltaic module and the purlin. In one embodiment, the drive rod 210 is used to abut against the opposite side of the two bending portions 330, and the drive rod 210 is configured to rotate around its own axis to approach the relative drive block 220 to open the bending portion 330 to a first deformation state, so that the locking portion 310 is partially aligned with the notch edge of the purlin 400 on the axial direction of the drive rod 210, so as to limit the locking portion 310 from slipping out of the groove 410.

[0046] Specifically, when the deformable member 300 is in the initial state, the minimum distance between the two bent portions 330 is smaller than the radial dimension of the driving rod 210. Thus, when the driving rod 210 approaches the driving block 220, the driving rod 210 can push the two bent portions 330 relatively away from each other, thereby stretching the bent portions 330 to the first deformation state, so that the locking portion 310 is partially aligned with the notch edge of the purlin 400 in the axial direction of the driving rod 210, thereby limiting the locking portion 310 from escaping the groove 410, thereby improving the reliability of the photovoltaic module connection structure.

[0047] Among them, the opposite sides of the two bending portions 330 are both in contact with the notch of the groove 410, so that the rotation of the deformable member 300 is restricted, thereby limiting the rotation of the driving block 220, so that the driving rod 210 moves relative to the driving block 220 during the process of rotating around its own axis.

[0048] Referring to Figures 1, 7 and 8, Figure 8 is a third cross-sectional view of the photovoltaic module connection structure provided by an embodiment of the utility model, the photovoltaic module and the purlin. In one embodiment, when the bending portion 330 is stretched to the first deformation state, the driving rod 210 is restricted from approaching the driving block 220, and the driving rod 210 is configured to rotate around its own axis to drive the driving block 220 to approach the connecting portion 320, so as to stretch the bending portion 330 from the first deformation state to the second deformation state, so that the locking portion 310 is aligned with the hook 420 of the purlin 400 in the axial direction of the driving rod 210.

[0049] Specifically, the driving rod 210 is inserted into the driving block 220, and the portion of the driving block 220 located outside the matching groove 340 has a larger size in the radial direction of the driving rod 210 than the driving rod 210. When the bending portion 330 is in the first deformation state, the driving rod 210 is restricted from approaching the driving block 220. In the process of the driving rod 210 rotating around its own axis, the driving block 220 approaches the driving rod 210, thereby extending into between the two bending portions 330. Since the portion of the driving block 220 located outside the matching groove 340 has a larger size in the radial direction of the driving rod 210 than the driving rod 210, the two bending portions 330 can be continuously pushed away from each other, so as to open the bending portion 330 from the first deformation state to the second deformation state, so as to align the locking portion 310 with the hook 420 of the purlin 400 in the axial direction of the driving rod 210, thereby facilitating the locking of the locking portion 310 with the locking ring of the purlin 400.

[0050] It should be noted that, when the driving block 220 approaches the relative connecting portion 320, since the driving block 220 abuts against the side of the bending portion 330 facing away from the pressing piece 100, the driving block 220 applies a thrust toward the pressing piece 100 to the bending portion 330, and the locking portion 310 and the notch edge of the purlin 400 are partially aligned in the axial direction of the driving rod 210, thereby limiting the locking portion 310 from slipping out of the groove 410 of the purlin 400, thereby improving the reliability of the photovoltaic module connection structure.

[0051] Furthermore, a protrusion 230 is provided at one end of the driving rod 210 away from the driving block 220. The protrusion 230 is used to abut against the pressing piece 100 when the bending portion 330 is in the first deformation state, thereby limiting the driving rod 210 from approaching the driving block 220, so that the driving block 220 approaches the pressing piece 100.

[0052] Referring to Figures 1, 8 and 9, Figure 9 is a fourth cross-sectional view of a photovoltaic module connection structure provided by an embodiment of the utility model in cooperation with a photovoltaic module 500 and a purlin 400. In one embodiment, when the bending portion 330 is expanded to the second deformation state, the driving block 220 abuts against the connecting portion 320, and the driving rod 210 is configured to rotate around its own axis to drive the driving block 220 to drive the deformation member to approach the relative pressing member 100, so that the locking portion 310 is locked with the locking ring.

[0053] Specifically, when the bending portion 330 is expanded to the second deformation state, the driving block 220 abuts against the connecting portion 320, so that the approach of the driving block 220 relative to the connecting portion 320 is restricted, so that in the process of the driving rod 210 driving the driving block 220 to approach the compression piece 100, the driving block 220 can drive the deformable member 300 to move synchronously along the axial direction of the driving rod 210, so that the locking portion 310 can approach the locking ring relative to the locking ring for locking, so as to limit the relative distance between the deformable member 300 and the purlin 400, and the driving block 220 abuts against the connecting portion 320, and the protrusion 230 abuts against the compression piece 100, so that the relative distance between the compression piece 100 and the purlin 400 is restricted, so that the compression piece 100 and the purlin 400 can stably clamp the photovoltaic component 500, thereby improving the reliability of the photovoltaic component connection structure.

[0054] Among them, the distance between the clamp 100 and the purlin 400 is adjustable, so that the clamp 100 and the purlin 400 can clamp the photovoltaic modules 500 of different thicknesses, and can achieve compatibility with dimensional deviations in the installation thickness direction, thereby improving the adaptability of the photovoltaic module connection structure.

[0055] Furthermore, one end of the bending portion 330 away from the connecting portion 320 is bent toward a side away from the driving rod 210 to form a mounting groove, and the mounting groove is configured as a locking portion 310. The notch of the groove 410 on the purlin 400 has a hook 420 extending inwardly, and the hook 420 is configured as a locking ring. The mounting groove and the hook 420 are engaged and matched to achieve stable locking of the deformable member 300 and the purlin 400. Among them, the locking setting of the mounting groove and the hook 420 can achieve the deviation of the width size of the purlin 400, thereby further improving the adaptability of the photovoltaic module connection structure.

[0056] Referring to Figures 6, 7, 8 and 9, in one embodiment, the deformable member 300 also includes a stop member 350, which is connected to the bending portion 330 and abuts against the pressing member 100. The stop member 350 is configured to be deformed when the deformable member approaches the pressing member 100 to apply a force to the connecting portion 320 away from the pressing member 100, so that the connecting portion 320 can be stably abutted against the driving block 220 to prevent loosening, thereby improving the reliability of the photovoltaic module connection structure.

[0057] 6, 7, 8 and 9, in one embodiment, the stop member 350 includes a stop rod 351, one end of the stop rod 351 is connected to one end of the bending portion 330 close to the pressing member 100, and the other end of the stop rod 351 abuts against the pressing member 100. The stop rod 351 is configured to rotate relative to the pressing member 100 when the deformable member 300 approaches the pressing member 100 to tip over.

[0058] Specifically, the stopper rod 351 is connected to one end of the bending portion 330 away from the locking portion 310. When the deformable member 300 approaches the pressing member 100, the stopper rod 351 rotates relative to the pressing member 100 under the pressure of the pressing member 100, thereby bending relative to the bending portion 330 to tilt, thereby providing space for the connection portion 320 to approach the pressing member 100. Since the stopper rod 351 is bent relative to the bending portion 330, the stopper rod 351 can exert a force on the connection portion 320 away from the pressing member 100, thereby preventing looseness and improving the reliability of the photovoltaic module connection structure.

[0059] Furthermore, there are two stop rods 351, which are respectively connected to the two bending portions 330, and when the bending portions 330 are in the second deformation state, the stop rod 351 is inclined relative to the pressing piece 100, so that in the process of the connecting portion 320 approaching the pressing piece 100, the connecting portion 320 can apply an axial force to the stop rod 351 along the driving rod 210, so that the stop rod 351 tilts relative to the connecting portion 320.

[0060] Furthermore, when the deformable member 300 is in the initial state, the stopper rod 351 is perpendicular to the pressure member 100, so that the connection portion 320 can be stably restricted from approaching the pressure member 100, so as to restrict the locking portion 310 from escaping from the groove 410, thereby improving the reliability of the photovoltaic module connection structure. When the bending portion 330 is stretched to the first deformation state, the ends of the two stopper rods 351 away from the bending portion 330 are relatively bent under the drive of the corresponding bending portion 330, so that when the connection portion 320 approaches the pressure member 100, the ends of the two stopper rods 351 away from the bending portion 330 can be relatively tilted.

[0061] Referring to Figures 4, 8 and 9, in one embodiment, an avoidance groove 321 is provided on the area between the two stop rods 351 on the connection portion 320, and the avoidance groove 321 is used to accommodate the stop rod 351, so that the connection portion 320 can fit with the compression piece 100, thereby increasing the contact area between the deformable member 300 and the compression piece 100, so that the deformable member 300 and the protrusion 230 can stably clamp the compression piece 100, thereby improving the stability of the compression piece 100 and the purlin 400 clamping the photovoltaic module 500.

[0062] 3 , 5 , 6 and 7 , in one embodiment, the driving block 220 includes two oppositely disposed introduction surfaces 221 , the two introduction surfaces 221 are respectively used to abut against opposite sides of the two bending portions 330 , and in the direction in which the deformation member 300 points to the pressing member 100 , the distance between the two introduction surfaces 221 gradually decreases.

[0063] Specifically, when the bending portion 330 is in the first deformation state, the two introduction surfaces 221 are partially located between the two bending portions 330, and the minimum distance between the two introduction surfaces 221 is smaller than the radial dimension of the driving rod 210. Therefore, in the process of the driving block 220 approaching the connecting portion 320 relative to the driving rod 210, the opposite side of the bending portion 330 can abut against the introduction surface 221, and as the driving block 220 continues to approach the connecting portion 320 relative to the driving rod 210, the two introduction surfaces 221 gradually push the two bending portions 330 away, thereby improving the reliability of the connection structure of the photovoltaic module.

[0064] Referring to Figures 3, 5, 6 and 7, in one embodiment, the driving block 220 includes a matching portion 222 and a pushing portion 223, the matching portion 222 is connected to the side of the pushing portion 223 facing the connecting portion 320, and is used to abut against the connecting portion 320, and the pushing portion 223 is used to abut against the bending portion 330; the matching portion 222 and the pushing portion 223 are provided with a threaded hole 224 for accommodating the driving rod 210, and the hole wall of the threaded hole 224 is provided with a notch 225 so that the driving rod 210 is partially exposed outside the threaded hole 224 to abut against the bending portion 330.

[0065] Specifically, the introduction surface 221 is provided on the pushing portion 223, and the notch 225 is provided at the connection between the pushing portion 223 and the matching portion 222. Since the minimum distance between the two introduction surfaces 221 is smaller than the radial dimension of the driving rod 210, the notch 225 is formed at the connection between the pushing portion 223 and the matching portion 222, so that the driving rod 210 is partially exposed to the outside, so as to abut against the opposite side of the two bending portions 330. When the bending portion 330 is in the second deformation state, the matching portion 222 abuts against the side of the connecting portion 320 away from the pressing member 100, thereby limiting the relative movement of the driving block 220 and the connecting portion 320, so that when the driving rod 210 continues to rotate around its own axis, the driving block 220 can drive the deformation member 300 to approach the pressing member 100, thereby driving the locking portion 310 to abut against the locking ring of the purlin 400, so as to achieve the locking of the locking portion 310 and the purlin 400.

[0066] Referring to FIG. 1 and FIG. 7 , in one embodiment, the pressing member 100 includes an abutting plate 120 and two crimping plates 110, the two crimping plates 110 are respectively connected to the two ends of the abutting plate 120, the abutting plate 120 is sleeved on the driving rod 210, and the crimping plate 110 is used to be crimped to the photovoltaic module 500. The abutting plate 120 is provided with a drainage groove 130, and the driving rod 210 is passed through the bottom of the drainage groove 130.

[0067] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
