[0002] Photovoltaic modules usually need to be installed on the roof of a building or a photovoltaic bracket to support and fix the photovoltaic modules. In order to facilitate the installation of photovoltaic modules, a support plate is usually required. The support plate can be directly connected to the roof or the bracket, and then the photovoltaic modules can be installed on the support plate.

[0005] In order to solve the above technical problems, this application is implemented as follows:

[0006] In a first aspect, the present application discloses an assembled photovoltaic assembly, wherein the assembled photovoltaic assembly has a first direction and a second direction intersecting each other, and the assembled photovoltaic assembly comprises:

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] The embodiment of the present application provides an assembled photovoltaic module, which can complete part of the installation work before leaving the factory. In this way, after the assembled photovoltaic module is transported to the installation site, only the remaining installation needs to be completed, which greatly improves the installation efficiency of the photovoltaic module on the roof or photovoltaic bracket.

[0038] Reference Figure 1 , showing one of the front structural schematic diagrams of the support member of the assembled photovoltaic module described in the embodiment of the present application, referring to Figure 2 , showing Figure 1 The second schematic diagram of the front structure of the support member shown in FIG. Figure 3 , showing Figure 1 The back structural diagram of the support member is shown in FIG. Figure 4 , showing a schematic diagram of the assembly process of an assembled photovoltaic module according to an embodiment of the present application, referring to Figure 5 , showing Figure 4 The schematic diagram of the structure of the assembled photovoltaic module after assembly is shown.

[0039] like Figures 1 to 5 As shown, the assembled photovoltaic assembly may include: a support member 1, the support member 1 includes a support plate 11, the support plate 11 may include a front side and a back side that are arranged in opposite directions, the back side is provided with a hook 13, the hook 13 may be used to be hung on a target installation object to connect the support member 1 to the target installation object; and a photovoltaic panel 2, the photovoltaic panel 2 is installed on the front side connected to the support plate 11. The hook 13 may specifically include a first hook 131 and a second hook 132 that are spaced apart along a first direction y, and the orthographic projection of the first hook 131 along the first direction y and the orthographic projection of the second hook 132 along the first direction y are staggered.

[0040] Specifically, the first hook 131 can be used to hang on one of the two adjacent purlins 3 along the first direction y, and the second hook 132 can be used to hang on the other of the two adjacent purlins 3 along the first direction y to limit the movement of the support member 1 along the first direction y.

[0041] In practical applications, the first hook 131 and the second hook 132 on the back of the support plate 11 can be respectively hooked on two upper and lower adjacent purlins 3 to lock the upper and lower positions of the support member 1 on the purlin 3. The first hook 131 and the second hook 132 can be specifically hooked on the upper flange plate of the purlin 3. In practical applications, at least one of the first hook 131 and the second hook 132 can also be connected to the upper flange plate of the purlin 3 by a fastener 4 such as a bolt or a screw to prevent the support member 1 from moving on the purlin 3 in the front-to-back direction or the left-to-right direction, so as to improve the connection reliability of the assembled photovoltaic module on the purlin 3.

[0042] like Fig.10 As shown, when multiple support members 1 are arranged along the first direction y, the second hook 132 on the upper first support member 1 and the first hook 131 on the lower first support member 1 are hung on the same purlin 3. In some optional embodiments of the present application, the orthographic projection of the first hook 131 along the first direction y and the orthographic projection of the second hook 132 along the first direction y are staggered, so that the first hook 131 and the second hook 132 in two different support members 1 can be staggered accordingly when hung on the same purlin 3, so as to avoid interference between the first hook 131 and the second hook 132, thereby improving the convenience and stability of hanging the support member 1 on the purlin 3.

[0043] Specifically, the orthographic projection of the first hook 131 along the first direction y and the orthographic projection of the second hook 132 along the first direction y can be misaligned by projecting the first hook 131 and the second hook 132 along the first direction y, so that their projections do not overlap, thereby forming a misaligned effect. When a plurality of the assembled photovoltaic components are placed along the first direction y, the second hook 132 on the assembled photovoltaic component located above and the first hook 131 on the assembled photovoltaic component located below will be hung on the same purlin. Since the orthographic projection of the first hook 131 along the first direction y and the orthographic projection of the second hook 132 along the first direction y are misaligned, the second hook 132 of the assembled photovoltaic component above and the first hook 131 of the assembled photovoltaic component below can be misaligned accordingly, so that interference between the first hook 131 and the second hook 132 hung on the same purlin 3 can be avoided.

[0044] Optionally, the number of the first hooks 131 and the number of the second hooks 132 may be equal or unequal, and this embodiment of the present application does not specifically limit this.

[0045] like Figure 3 As shown, the number of the first hook 131 is one, the number of the second hook 132 is two, and the orthographic projection of the first hook 131 along the first direction y is located between the orthographic projections of the two second hooks 132 along the first direction y. In this way, when multiple support members 1 are arranged up and down along the first direction y, the first hook 131 of the lower support member 1 can be located between the two second hooks 132 of the upper support member 1, avoiding mutual interference between the first hook 131 and the second hook 132. Moreover, for the same support member 1, one first hook 131 and two second hooks 132 can realize three-point hanging positioning on the purlin 3, so that the support member 1 can be reliably hung on the purlin 3.

[0046] like Figure 5 As shown, after the assembled photovoltaic module is assembled, there is a gap s between the photovoltaic panel 2 and the support plate 11 , and the gap s can be used for heat dissipation of the photovoltaic panel 2 to improve the performance and service life of the photovoltaic panel 2 .

[0047] In the embodiment of the present application, the assembled photovoltaic assembly may include a support 1 and a photovoltaic panel 2, and the photovoltaic panel 2 may be connected to the support 1. A hook 13 is provided on the support 1, and the support 1 may be connected to the target installation object through the hook 13. Since the photovoltaic panel 2 is directly connected to the support 1, the photovoltaic panel 2 is reliably installed on the support 1 and is not easy to loosen. Moreover, in the process of installing the assembled photovoltaic assembly to the target installation object, it is only necessary to hang the hook 13 of the support plate 11 on the target installation object, avoiding the operation of using an additional pressure block to connect the photovoltaic panel 2 and the support 1 to the target object, the installation process is simple, the number of parts used is extremely small, the installation cost is low and the installation efficiency is high. In addition, since the orthographic projection of the first hook 131 along the first direction y is misaligned with the orthographic projection of the second hook 132 along the first direction y, the interference of the first hook 131 and the second hook 132 hung on the same purlin 3 of the target installation object can also be avoided, thereby improving the convenience and stability of the support 1 on the purlin 3.

[0048] In practical applications, the target installation object can be any object on which the assembled photovoltaic module can be installed, such as the roof of a building, a photovoltaic bracket, etc. This application only takes the target installation object as the purlin 3 of the roof as an example for explanation, and other target installation objects can be implemented by reference. During the transportation of the assembled photovoltaic module, the support 1 and the photovoltaic panel 2 can be transported separately, or the photovoltaic panel 2 can be assembled on the support 1 and then transported as a whole. The embodiment of this application does not specifically limit the transportation method of the assembled photovoltaic module.

[0049] In a specific application, the assembled photovoltaic assembly described in the embodiment of the present application may include an intersecting first direction y and a second direction x. The first direction y may specifically be the up-down direction of the target installation object, and the second direction x may be the left-right direction of the target installation object; or, the first direction y may specifically be the left-right direction of the target installation object, and the second direction x may be the up-down direction of the target installation object. The embodiment of the present application is only described by taking the first direction y as the up-down direction of the target installation object and the second direction x as the left-right direction of the target installation object as an example.

[0050] like Figures 1 to 4As shown, along the second direction x, the first overlap portion 14 and the second overlap portion 15 are respectively arranged on both sides of the support member 1. When a plurality of the assembled photovoltaic modules are arranged along the second direction x, in two adjacent assembled photovoltaic modules, the first overlap portion 14 in one support member 1 at least partially overlaps with the second overlap portion 15 in another support member 1 to prevent water from leaking from between the two adjacent support members 1 along the second direction x, thereby achieving a waterproof function. The cross-sectional shapes of the first overlap portion 14 and the second overlap portion 15 are both triangular to achieve better waterproof performance.

[0051] In a specific application, the first overlap portion 14 and the second overlap portion 15 can form a mutually interlocking male-female overlap fit, that is, the first overlap portion 14 and the second overlap portion 15 have the same cross-section shape and slightly different sizes. Figures 1 to 3 As shown, the second overlapping portion 15 with a slightly larger size can be used as a male buckle edge, and the first overlapping portion 14 with a slightly smaller size can be used as a female buckle edge. Among the two support members 1 adjacently arranged along the second direction x, the second overlapping portion 15 of one support member 1 can overlap the first overlapping portion 14 of the other support member 1.

[0052] like Figure 1 and Figure 2 As shown, a buckle 12 is provided on the front of the support plate 11, and the frame of the photovoltaic panel 2 is snapped with the buckle 12 to connect the photovoltaic panel 2 to the support 1. By snapping the photovoltaic panel 2 directly on the buckle 12 of the support 1, the photovoltaic panel 2 can be installed on the support 1 reliably and not easily loosened.

[0053] In a specific application, a base for raising the photovoltaic panel 2 may also be provided on the buckle 12. Thus, after the photovoltaic panel 2 is snapped onto the buckle 12, a gap s may be provided between the photovoltaic panel 2 and the support member 1 due to the presence of the base to facilitate heat dissipation.

[0054] like Figure 1 , Figure 2 As shown, the buckle 12 may include a first buckle 121 and a second buckle 122 spaced apart along the second direction x; wherein the first buckle 121 may be used to be engaged with a side frame of the photovoltaic panel 2 along the second direction x, and the second buckle 122 may be used to be engaged with another side frame of the photovoltaic panel 2 along the second direction x; a guide portion 1220 is provided on the second buckle 122, and the guide portion 1220 may be used to slide and guide the frame of the photovoltaic panel 2 into the second buckle 122, so as to achieve smooth engagement between the photovoltaic panel 2 and the support member 1.

[0055] like Figure 4As shown, the first buckle 121 can be a flat buckle, and the length of the first buckle 121 and the frame of the photovoltaic panel 2 is relatively long. The second buckle 122 can be provided with a guide portion 1220. In the process of snapping the photovoltaic panel 2 to the support member 1, the frame of one side of the photovoltaic panel 2 can be snapped to the first buckle 121 first, and then the frame of the other side of the photovoltaic panel 2 is pressed downward toward the second buckle 122, and the frame is snapped to the second buckle 122 by sliding the frame on the guide portion 1220 of the second buckle 122 (as shown in FIG. Figure 5 As shown), so as to achieve smooth snap-fitting of the photovoltaic panel 2 on the support 1.

[0056] Optionally, the guide portion 1220 is a slope structure, and when the photovoltaic panel 2 is snapped onto the support member 1 , the frame of the photovoltaic panel 2 can slide along the slope structure so that the frame can be smoothly snapped into the second buckle 122 .

[0057] Specifically, in order to achieve reliable snap connection of the photovoltaic panel 2 on the support member 1 and prevent the photovoltaic panel 2 from loosening, the number of the first snap 121 and the second snap 122 are at least two respectively. The drawings of the embodiment of the present application only show the case where the number of the first snap 121 and the second snap 122 are both three. In actual applications, the number of the first snap 121 and the second snap 122 can also be 2, 4 or 6, etc., and the embodiment of the present application does not limit this.

[0058] like Figures 1 to 3 As shown, the support plate 11 is provided with an opening 123, which can be used for cable routing and heat dissipation of the photovoltaic panel 2. The edge of the opening 123 is provided with a flange 124 protruding toward the front, which can be used to prevent water from entering the opening 123 and play a waterproof role. The opening 123 is provided with a guide portion, which can be used to guide the water flow to prevent water from flowing into the opening 123.

[0059] In some optional embodiments of the present application, the flange 124 and the support plate 11 are integrally formed, that is, during the processing of the support plate 11, the flange 124 can be formed by performing operations such as stamping at the opening 123 on the support plate 11. In this way, it is avoided to set additional parts on the support plate 11 to achieve the water blocking operation, thereby simplifying the structure of the support plate 11 and reducing the processing difficulty of the support plate 11.

[0060] And / or, the opening 123 and the guide portion are an integrally formed structure, and the edges of the opening and the guide portion are both provided with flanges 124. In a specific application, one side of the opening 123 can be provided as an inverted "V"-shaped guide portion, and the guide portion is conveniently provided with a flange 124 that can be used for waterproofing. When the assembled photovoltaic module is installed obliquely on the target installation object, the inverted "V"-shaped guide portion can be located at the top, so that in the case of rain, the water flowing to the opening 123 can flow along the edge of the guide portion, and under the guiding effect of the guide portion, it can flow to the area outside the opening 123, thereby preventing water from flowing into the opening 123.

[0061] It should be noted that in practical applications, those skilled in the art can set the size of the opening 123 according to actual needs. If the opening 123 is too small, it is inconvenient for wiring and heat dissipation. If the opening 123 is too large, the strength of the support plate 11 is too weak and the support is not good. Therefore, the size of the opening 123 needs to be set according to actual needs.

[0062] Reference Figure 6 , showing a schematic diagram of the front structure of the support member according to an embodiment of the present application installed on the target installation object, referring to Figure 7 , showing a schematic diagram of the back structure of the support member according to an embodiment of the present application installed on the target installation object, referring to Figure 8 , showing Figure 6 The detailed structural diagram of the structure A position shown is shown in FIG. Fig. 9 , showing Figure 6 The detailed structural diagram of the structure B position shown is shown in FIG. Fig.10 , showing Figure 7 Detailed structural diagram of the structure C position is shown.

[0063] like Figure 6 , Figure 7 As shown, the target installation object may include a plurality of purlins 3 arranged at intervals along a first direction y, and a plurality of support members 1 may be connected to the purlins 3 along the first direction y and the second direction x, respectively. Figure 8 As shown, in two support members 1 adjacently arranged along the second direction x, the second overlapping portion 15 of the support member 1A on the left side can overlap the first overlapping portion 14 of the support member 1B on the right side to achieve left-right overlapping of the two support members 1. Fig. 9 As shown, in two support members 1 adjacently arranged along the first direction y, the support plates 11 of the upper support members 1C and 1D can be overlapped on the support plates 11 of the lower support members 1A and 1B to achieve the upper and lower overlap of the support members 1. In practical applications, through the left-right overlap and the upper-lower overlap of the support members 1, the integral overlap of multiple support members 1 can be achieved, and the waterproof effect is better.

[0064] like Figure 3 As shown, the support plate 11 may include a first edge 111 and a second edge 112 spaced apart along the first direction y; the first hook 131 is disposed at the first edge 111, and the second hook 132 is close to the second edge 112 and has a distance from the second edge 112. In this way, when a plurality of support members 1 are disposed along the first direction y, in two adjacent support plates 11, the second hook 132 on the upper first support member 1 and the first hook 131 on the lower first support member 1 are hung on the same purlin 3, so that the portion from the second hook 132 to the second edge 112 on the support plate 11 of the upper support member 1C overlaps the support plate 11 of the lower support member 1A, thereby realizing the upper and lower overlap of the support members 1.

[0065] like Figure 3 As shown, the first edge 111 is provided with a notch 113 at a position corresponding to the second hook 132. Fig.10 As shown, in the case where multiple support members 1 are arranged along the first direction y, the second hook 132 of the upper support member 1 can be embedded in the notch 113 of the lower support member 1 during installation, so as to limit the second hook 132 of the upper support member in the second direction x through the notch 113, thereby improving the installation accuracy of the upper support member 1. In addition, after the two second hooks 132 on the upper support member 1 and the first hook 131 of the lower support member 1 are installed on the same purlin 3, since the two second hooks 132 can be located in the notch 113, the bottom of the notch 113 can be close to the purlin 3, so that the two second hooks 132 and the first hook 131 installed on the same purlin 3 can be located on the same horizontal line, making the installed assembly more stable.

[0066] In the embodiment of the present application, the purlin 3 may include an upper flange plate, and the first hook 131 and the second hook 132 are both provided with a snap-fitting space for snapping with the upper flange plate; wherein the thickness of the snap-fitting space of the first hook 131 is greater than or equal to the thickness of the upper flange plate, so that the first hook 131 is directly snap-fitted to the upper flange plate of the purlin 3. The thickness of the snap-fitting space of the second hook 132 is greater than or equal to the sum of the thicknesses of the upper flange plate and the support plate 11, so that the second hook 132 is snap-fitted to the upper flange plate and the support plate 11 of the support member 1 below.

[0067] In actual applications, the thickness of the engagement space of the second hook 132 and the first hook 131 is different, which can be externally manifested as the difference in thickness between the first hook 131 and the second hook 132. Figure 5 As shown, the thickness of the second hook 132 is significantly greater than the thickness of the first hook 131 .

[0068] The following provides an example of installing the assembled photovoltaic assembly described in an embodiment of the present application on the target installation object:

[0069] 1. The photovoltaic panel 2 and the support plate 11 are prefabricated and assembled before leaving the factory to form an assembled product. Specifically, the front buckle 12 of the support member 1 is buckled with the frame of the photovoltaic panel 2, the first buckle 121 is first buckled with one side of the frame, and the frame on the other side is then slid and buckled onto the second buckle 122.

[0070] 2. Find the roof installation starting point according to the design and install the first assembled photovoltaic module. Specifically, by hanging the hook 13 on the back of the support member 1 on the upper flange plate position of the roof purlin 3, and then installing the fastener 4 at the first hook 131 position, the installation stability of the assembled photovoltaic module on the purlin 3 is enhanced.

[0071] 3. Install the second adjacent prefabricated photovoltaic modules. Specifically, the second prefabricated photovoltaic module is fixed to the purlin 3 in the same manner as the first prefabricated photovoltaic module, and only the first overlap portion 14 and the second overlap portion 15 at the adjacent positions of the first prefabricated photovoltaic module and the second prefabricated photovoltaic module need to be overlapped.

[0075] In summary, the assembled photovoltaic assembly described in the embodiments of the present application may at least include the following advantages:

[0076] In an embodiment of the present application, the assembled photovoltaic assembly may include a support member and a photovoltaic panel, and the photovoltaic panel may be connected to the support member. A hook is provided on the support member, and the support member may be connected to the target installation object through the hook. In the process of installing the assembled photovoltaic assembly to the target installation object, it is only necessary to hook the hook of the support plate on the target installation object, thereby avoiding the operation of using an additional pressure block to connect the photovoltaic panel and the support member to the target object. The installation process is simple, the number of parts used is extremely small, the installation cost is low, and the installation efficiency is high. In addition, since the orthographic projection of the first hook along the first direction is misaligned with the orthographic projection of the second hook along the first direction, the interference of the first hook and the second hook hung on the same purlin of the target installation object can also be avoided, thereby improving the convenience and stability of hanging the support member on the purlin.

[0077] Reference Fig.11 , shows a schematic diagram of the structure of a photovoltaic system described in an embodiment of the present application. Fig.11 As shown, the photovoltaic system may specifically include: a target installation object and the assembled photovoltaic assembly described in any of the above embodiments; wherein the hook on the support member 1 of the assembled photovoltaic assembly is hooked to the target installation object. In this way, the operation of using an additional pressing block to connect the photovoltaic panel 2 and the support member 1 to the target object can be avoided, the installation process is simple, the number of parts used is extremely small, the installation cost is low, and the installation efficiency is high.

[0078] In some optional embodiments of the present application, the photovoltaic system may further include a fastener 4, which passes through the hook and is connected to the target installation object to fix the support member 1 to the target installation object, further improving the connection stability of the assembled photovoltaic component on the target installation object.

[0079] Optionally, the support plate 11 may include a first edge 111 and a second edge 112 spaced apart along the first direction y; the first hook 131 is disposed at the first edge 111, and the second hook 132 is close to the second edge 112 and has a distance from the second edge 112. In this way, when a plurality of support members 1 are disposed along the first direction y, in two adjacent support plates 11, the second hook 132 on the upper first support member 1 and the first hook 131 on the lower first support member 1 are hung on the same purlin 3, so that the portion from the second hook 132 to the second edge 112 on the support plate 11 of the upper support member 1 overlaps the support plate 11 of the lower support member 1, thereby achieving upper and lower overlap of the support members 1, so as to prevent water from leaking from between the two adjacent support members 1 along the first direction y, and achieve a waterproof function.

[0080] And / or, along the second direction x, the first overlap portion 14 and the second overlap portion 15 are respectively arranged on both sides of the support member 1. When a plurality of the assembled photovoltaic modules are arranged along the second direction x, in two adjacent assembled photovoltaic modules, the first overlap portion 14 in one support member 1 at least partially overlaps with the second overlap portion 15 in another support member 1 to prevent water from leaking from between the two adjacent support members 1 along the second direction x, thereby achieving a waterproof function. The cross-sectional shapes of the first overlap portion 14 and the second overlap portion 15 are both triangular to achieve better waterproof performance.

[0081] In a specific application, the first overlap portion 14 and the second overlap portion 15 can form a mutually interlocking male-female overlap fit, that is, the first overlap portion 14 and the second overlap portion 15 have the same cross-section shape and slightly different sizes. Figures 1 to 3 As shown, the second overlapping portion 15 with a slightly larger size can be used as a male buckle edge, and the first overlapping portion 14 with a slightly smaller size can be used as a female buckle edge. Among the two support members 1 adjacently arranged along the second direction x, the second overlapping portion 15 of one support member 1 can overlap the first overlapping portion 14 of the other support member 1.

[0082] It should be noted that the assembled photovoltaic module described in the embodiment of the present application has the same structure as the assembled photovoltaic module described in any of the above embodiments, and its beneficial effects are similar, which will not be repeated here.
