It should be understood that the specific examples described herein are only used to explain the present utility model and do not limit the present utility model.

[0038] In the related art, in a photovoltaic power station, photovoltaic modules are installed on a bracket and need to be fixed by the combination of bolts and pressing blocks, but there is a gap between the photovoltaic modules, which wastes space. Another installation method is one-way insertion type installation, but it is not easy to disassemble after installation, which causes difficulty in the later maintenance of the photovoltaic modules.

[0039] In view of the above problems, the connecting piece provided in the example embodiment of the present utility model is used to fix the photovoltaic module and the bracket. The connecting piece can be connected by insertion, and the stress section is located between the frame of the photovoltaic module and the bracket after connection. When disassembling, the plug-in part of the connecting piece is pressed out, so that the two objects are easy to install and disassemble.

[0040] It should be noted that the two target objects connected by the connecting piece in the example embodiment of the present utility model can be photovoltaic modules and brackets, and can also be other two objects to be connected that need to be disassembled. In the following, the two target objects are taken as examples of photovoltaic modules and brackets.

[0041] Figure 1 is a structural schematic view of a connecting piece according to the embodiment of the present application. As shown in Figure 1 The connecting piece 100 provided by the exemplary embodiment of the present application comprises a substrate 20 and first and second connecting parts respectively arranged on two surfaces of the substrate 20, the first and second connecting parts being respectively used for connecting two target objects; the first connecting part comprises two opposite plug-in parts 10, the two plug-in parts 10 being mirror-symmetrical about a reference surface, the reference surface being perpendicular to the substrate 20; each plug-in part 10 comprises a force receiving segment 114, a first force transmission segment 111 and a first plug-in segment 112 connected in sequence, the force receiving segment 114 being connected to the substrate 20, the force receiving segment 114 and the first plug-in segment 112 being parallel to the reference surface, the first force transmission segment 111 being perpendicular to the reference surface, and the distance between the force receiving segment 114 and the reference surface being greater than the distance between the first plug-in segment 112 and the reference surface; each plug-in part 10 further comprises a first hook part 113 arranged at one end of the first plug-in segment 112, the first hook part 113 being located on the side of the first plug-in segment 112 away from the reference surface.

[0042] Figure 2 is an axonometric structural schematic view of a photovoltaic combined structure according to the embodiment of the present application. As shown in Figure 2 and Figure 7 The first connecting part can be mounted on a frame 200 of a photovoltaic module, and the second connecting part can be detachably mounted on a support 300. The force receiving segment 114 of each plug-in part 10 is located between the frame 200 and the support 300, when the two are needed to be detached, the two force receiving segments 114 are pressed to be inwardly contracted, and then the first force transmission segments 111 drive the first plug-in segments 112 to be inwardly contracted at the same time, that is, the two first plug-in segments 112 are close to each other. At this time, the two first hook parts 113 can be detached from the clamping parts 304 on the support 300, and the detachment is completed.

[0043] Further, when the plug-in part 10 is needed to be mounted to the clamping part 304 on the support 300, the position at the top of the plug-in part 10 is pressed, so that the two first hook parts 113 pass through between the two clamping parts 304, the two first plug-in segments 112 are clamped in the clamping part 304, and the first hook part 113 is abutted on the bottom surface of the clamping part 304, thereby preventing the connecting piece 100 from being detached from the clamping part 304.

[0044] Exemplarily, the first hook part 113 extends outwardly on the side of the first plug-in segment 112 away from the reference surface, and has an inclined guide surface on the side of the first hook part 113 away from the substrate 20, so as to easily pass through the clamping part 304 on the support 300 and be fixed.

[0045] As shown in Figure 1As shown, the two plug-in portions 10 are arranged in mirror symmetry with respect to a reference plane, the reference plane is arranged along the vertical direction and is perpendicular to the substrate 20 and located at the middle part of the substrate 20. The two force receiving segments 114 and the substrate 20 are all plate-shaped structures and are arranged in a U shape. The top end of the first plug-in segment 112 and the bottom end of the force receiving segment 114 are connected through the first force transmission segment 111, the first force transmission segment 111 is parallel to the substrate 20, and the plug-in portion 10 overcomes the rigidity of the material to generate deformation, so that the two first hook portions 113 can be close to each other and be detached from the support 300, and through the elastic recovery after deformation, the two first hook portions 113 are fixedly installed on the support 300 and are far away from each other.

[0046] As shown in the figure, Figure 7 As shown, Figure 7 is a structural schematic view of a support according to the embodiment of the present application. The cross section of the support 300 is in a U shape, and the support 300 comprises a bottom plate 301 and two side plates 302. The bottom plate 301 is provided with an opening 303 for the second hook portion 123 to pass through. The end of each side plate 302 away from the bottom plate 301 comprises a clamping portion 304 matched with the first hook portion 113, and the clamping portion 304 is opposite to the bottom plate 301.

[0047] The end of each side plate 302 of the support 300 is inwardly and downwardly bent to form the clamping portion 304, the clamping portion 304 is generally in a U shape, and the face where the U-shaped opening is located is at the lower part of the top of the side plate 302 and is used for clamping the top face of the first hook portion 113. In order to make the first hook portion 113 smoothly reach the U-shaped opening face of the clamping portion 304, the wall faces of the two clamping portions 304 close to each other are in an inclined shape, which can be matched with the inclined guide face of the first hook portion 113 to easily form clamping.

[0048] In order to further enhance the connection stability between the connecting piece 100 and the support 300, as shown in the figure, Figure 1 As shown, each plug-in portion 10 of the connecting piece 100 further comprises a second force transmission segment 121 and a second plug-in segment 122 connected in sequence. The second force transmission segment 121 is perpendicular to the reference plane, and one end of the second force transmission segment 121 is connected to the middle part of the force receiving segment 114. The second plug-in segment 122 is parallel to the reference plane, and the distance between the second plug-in segment 122 and the reference plane is smaller than the distance between the first plug-in segment 112 and the reference plane. Each plug-in portion 10 further comprises a second hook portion 123 arranged at one end of the second plug-in segment 122, and the second hook portion 123 is located on the side of the second plug-in segment 122 away from the reference plane. The distance between the second hook portion 123 and the substrate 20 is greater than the distance between the first hook portion 113 and the substrate 20.

[0049] In actual application, the opening 303 on the bottom plate 301 of the bracket 300 is used to cooperate with the second plug-in section 122 and the second hook portion 123. When the top of the connecting piece 100 is pressed, the two first hook portions 113 are correspondingly clamped below the clamping portion 304 of the bracket 300; at the same time, the second hook portion 123 is squeezed to pass through the opening 303 of the bottom plate 301 and is clamped at the bottom of the bottom plate 301, as shown in Figure 8 Figure 8 is an axonometric structural schematic diagram of another view of the photovoltaic combination structure according to the embodiment of the present application.

[0050] When the two force sections 114 of the connecting piece 100 are moved to the reference surface under pressure, the first hook portion 113 and the second hook portion 123 are synchronously moved to the reference surface and are detached from the corresponding positions, thereby completing the disassembly.

[0051] In some embodiments, as shown in Figure 1 the second connecting portion provided by the exemplary embodiments of the present application comprises at least one mounting buckle 30, the mounting buckle 30 has a column body 32 away from a base plate 20 and a column cap 31, and the orthogonal projection of the column body 32 on the end face of the column cap 31 is located in the end face of the column cap 31.

[0052] The number of the mounting buckles 30 can be one, two or more, and when the number of the mounting buckles 30 is multiple, the arrangement direction of the multiple mounting buckles 30 is perpendicular to the reference surface. Hereinafter, the case that each second connecting portion has two mounting buckles 30 is taken as an example for description.

[0053] The arrangement direction of the two mounting buckles 30 is perpendicular to the reference surface, and the two mounting buckles 30 can more stably form the detachable connection between the connecting piece 100 and the frame 200 of the photovoltaic assembly.

[0054] Exemplarily, the mounting buckle 30 further comprises an elastic gasket, and the elastic gasket is sleeved on the column body 32.

[0055] Figure 3 is a structural schematic diagram of the frame 200 according to the embodiment of the present application. As shown in Figure 3 the frame 200 of the photovoltaic assembly comprises two long frame sections and two short frame sections, which are enclosed on the circumferential side of the photovoltaic laminate to play a protective and supporting role.

[0056] Specifically, the shape of each frame section can be the same, as shown in Figure 4 Figure 4 is a structural schematic diagram of the frame section according to the embodiment of the present application. The frame section comprises a bottom edge section 201, also called C face, and further comprises A face, B face and supporting face, wherein the A face, B face and supporting face are enclosed to form a receiving groove 202, which is cladded on the edge portion of the laminate, and the C face is used to support the whole frame section. That is, the bottom edge section 201 is located on the backlight side of the photovoltaic assembly.​​

[0057] Figure 5 is a structural schematic view of a bottom edge segment of a frame according to the embodiments of the present application. As shown in the figure, Figure 5 the frame 200 is provided with mounting holes on the bottom edge segment 201, which include a first hole 201a and a second hole 201b for the passage of a post cap 31, and the first hole 201a is matched with a post 32.

[0058] It should be noted that the mounting holes can be arranged on two long frame segments, as shown in the figure, Figure 3 They can also be arranged on two short frame segments, according to actual needs. Two mounting holes are arranged at positions close to the end portions of each long frame segment, respectively, to be used for cooperation with two mounting buckles 30 on the same connecting piece 100.

[0059] In actual application, the post cap 31 of the mounting buckle 30 passes through the second hole 201b and then moves to the first hole 201a, so that the post 32 and the elastic washer sleeved on the post 32 are clamped and fixed in the first hole 201a. It can be understood that the size of the first hole 201a is smaller than that of the second hole 201b, that is, the first hole 201a cannot pass through the post cap 31 with a larger size, thereby maintaining a stable connection effect.

[0060] The structure of the above connecting piece 100 mounted on the frame 200 is shown in the figure, Figure 6 Figure 6 is a structural schematic view of a frame and a connecting piece combined according to the embodiments of the present application. After the frame 200 and the four connecting pieces 100 are combined, they can be inserted into the corresponding positions of the support 300 in a press-fit manner, thereby forming a detachable connection between the connecting piece 100 and the frame 200 and the support 300.

[0061] Exemplarily, the post 32 is cylindrical, and the post cap 31 can be a tapered post cap with a sharp upper end and a thick lower end, so as to easily align with and pass through the second hole 201b.

[0062] In some embodiments, the connecting piece 100 can use a material with a higher tensile strength than steel and a lower elastic modulus than steel, such as aluminum or aluminum alloy, to facilitate later disassembly. If the phenomenon of electrolytic rusting is considered, the same material as the support 300 can also be used.

[0063] As can be seen from the above, the connecting piece 100 provided in the exemplary embodiments of the present application can be integrally formed, is convenient to install, has reversibility in the installation manner, and can be repeatedly used. Further, since the connecting piece 100 is entirely located on the back surface of the photovoltaic module (the C surface of the frame segment), it ensures that the front surface of the photovoltaic module is not blocked, and the appearance effect is better; and it does not occupy the edge space of the module, thereby better improving the space utilization.

[0064] As​Figure 2 The utility model exemplary embodiment further provides a photovoltaic combination structure, including support 300, frame 200 and connecting piece 100, frame 200 is detachably connected with support 300 through connecting piece 100, and frame 200 is the support frame 200 of photovoltaic module, and connecting piece 100 is the connecting piece of above-mentioned embodiment.

[0065] The utility model exemplary embodiment further provides a photovoltaic power station, including the photovoltaic combination structure of above-mentioned embodiment.

[0066] The above-mentioned photovoltaic combination structure, photovoltaic power station relative to the technical advantage that the prior art has with the advantage that the connecting piece has is same, and does not repeat here.
