Detailed embodiments

[0030] To make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe in detail the specific embodiments of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0031] In the description of the present application, it should be understood that if there are terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application.

[0032] In addition, if the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0033] In this application, unless otherwise clearly defined and limited, if terms such as "installed", "connected", "joined", "fixed", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] In this application, unless otherwise clearly defined and limited, if there is a description such as a first feature being "on" or "under" a second feature, the meaning can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over", and "on top of" the second feature can mean that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature is at a higher horizontal level than the second feature. The first feature being "under", "beneath", and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature is at a lower horizontal level than the second feature.

[0035] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right", and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0036] Refer to Figures 3 to 5As shown in the figure, a photovoltaic module mounting structure 100 provided by an embodiment of the present application includes a frame 110, a crimping kit, and a connecting member 140; the frame 110 is used to fix the photovoltaic laminate 300; the crimping kit includes a pressing block 120 and a purlin 130 spaced apart from the pressing block 120 in a first direction; a gap between the pressing block 120 and the purlin 130 forms a clamping space for accommodating the frame 110; the connecting member 140 penetrates through the pressing block 120 and the purlin 130 in the first direction and is capable of driving one of the pressing block 120 and the purlin 130 to move relative to the other in the first direction, so that the pressing block 120 and the purlin 130 respectively abut against two sides of the frame 110 in the first direction. Wherein, the first direction is the Figure 4 up and down direction in the figure, and is also the thickness direction of the frame 110.

[0037] For the above-mentioned photovoltaic module mounting structure 100, by maintaining a reasonable distance between the pressing block 120 and the purlin 130, it is convenient for the frame 110 to slide into the clamping space between the pressing block 120 and the purlin 130. After the frame 110 slides in, the distance between the pressing block 120 and the purlin 130 is adjusted by the connecting member 140, so that the pressing block 120 and the purlin 130 respectively press against the opposite sides of the frame 110. During the installation process, there is no need to flip the pressing block 120 or the purlin 130, which not only improves the installation convenience and installation efficiency of the photovoltaic module, but also resists the loads on the light-receiving surface and the backlight surface of the photovoltaic module by the pressing block 120 and the purlin 130 respectively pressing against two sides of the frame 110 in the first direction, improves its load resistance and other capabilities, and ensures its installation reliability.

[0038] As Figure 5 shown in the figure, specifically, a cavity 113 is formed on the frame 110, and the cavity 113 has an opening, which is convenient for the photovoltaic laminate 300 to slide into the cavity 113 through the opening. Further, the size of the opening of the cavity 113 (i.e., the dimension in the first direction) is slightly smaller than the dimension of the side wall of the cavity 113 (the side wall opposite to the opening) in the first direction, so as to be able to play a certain limiting role on the photovoltaic laminate 300 located in the cavity 113 and reduce the possibility of the photovoltaic laminate 300 coming out.

[0039] As Figure 1 and Figure 4As shown, in one embodiment, one of the pressing block 120 and the frame 110 is provided with a first limiting protrusion 122, and the other is provided with a first limiting groove 111 for engaging with the first limiting protrusion 122. Specifically in this embodiment, the pressing block 120 is provided with a first limiting protrusion 122, and the frame 110 is provided with a first limiting groove 111. Through the engaging cooperation between the first limiting protrusion 122 and the first limiting groove 111, the risk of displacement of the light-receiving surface of the photovoltaic laminate 300 when subjected to pressure such as wind and snow loads is reduced, and its load resistance performance is improved, thereby improving the reliability of the use of the photovoltaic module. For example, in Figure 2 In the embodiment, the light-receiving surface is the side of the photovoltaic laminate 300 facing the sun, that is, the upper end surface of the photovoltaic laminate 300. Of course, in other embodiments, the positions of the first limiting groove 111 and the first limiting protrusion 122 can also be interchanged, that is, the first limiting groove 111 is set on the pressing block 120, and the first limiting protrusion 122 is set on the frame 110.

[0040] like Figure 1 and Figure 4 As shown, in one embodiment, one of the purlin 130 and the frame 110 is provided with a second limiting protrusion 131, and the other is provided with a second limiting groove 112 for engaging with the second limiting protrusion 131. Specifically, the purlin 130 is provided with a second limiting protrusion 131, and the frame 110 is provided with a second limiting groove 112. Through the engaging cooperation between the second limiting protrusion 131 and the second limiting groove 112, the risk of displacement of the backlight surface of the photovoltaic laminate 300 when subjected to pressure such as wind and snow loads is reduced, and its load resistance performance is improved, thereby improving the reliability of the use of the photovoltaic module. For example, in Figure 2 In the embodiment, the backlight side is the side of the photovoltaic laminate 300 facing away from the sun, that is, the lower end face of the photovoltaic laminate 300. In other embodiments, the positions of the second limiting groove 112 and the second limiting protrusion 131 can also be interchanged, that is, the second limiting groove 112 is set on the purlin 130, and the second limiting protrusion 131 is set on the frame 110.

[0041] like Figure 4 As shown, in one embodiment, the photovoltaic assembly installation structure 100 further includes a locking member 150 sleeved on the outer peripheral wall of the connecting member 140, and the locking member 150 is used to abut against the pressing block 120 or the purlin 130. Figure 4 As shown, in some embodiments, the connecting member 140 is a hexagon socket bolt, the head of which extends into the pressing block 120 and abuts against the pressing block 120; the stem of which penetrates into the purlin 130, and the locking member 150 is a nut, which is sleeved on the stem and abuts against the purlin 130. Figure 7As shown, in other embodiments, the connecting member 140 is a T-shaped bolt, the head of which extends into the purlin 130 and abuts against the purlin 130; the rod portion thereof passes through the pressing block 120, and the locking member 150, such as a nut, is sleeved on the rod portion and abuts against the pressing block 120. Through the threaded fit of the connecting member 140 and the locking member 150, the pressing block 120 and the purlin 130 respectively abut against the frame 110, thereby ensuring the installation effect of the photovoltaic laminate 300.

[0042] As Figure 4 and Figure 7 shown, in one of the embodiments, the connecting member 140 is configured to rotatably about the first direction as an axis to drive the pressing block 120 and the purlin 130 to respectively abut against both sides of the frame 110 along the first direction. Specifically, the connecting member 140 is a bolt, and a thread is provided on its rod portion, and the rod portion is threadedly connected to the purlin 130. In this way, when the bolt is rotated, the purlin 130 will move along the axial direction of the bolt (which is also the first direction), so as to cooperate with the pressing block 120 to clamp on both sides of the frame 110. Of course, it is also possible that the rod portion of the bolt is threadedly connected to the pressing block 120, and by rotating the bolt, the pressing block 120 is moved, so as to press against both sides of the frame 110 with the purlin 130.

[0043] As Figure 4 shown, in one of the embodiments, the photovoltaic module mounting structure 100 further includes an elastic member 160 sleeved on the outer peripheral wall of the connecting member 140, and both ends of the elastic member 160 along the first direction are respectively connected to the pressing block 120 and the purlin 130. Specifically, both ends of the elastic member 160 along the first direction respectively abut against the pressing block 120 and the purlin 130 to provide a force for driving one of the pressing block 120 and the purlin 130 to move away from the other. In this way, the pressing block 120 is pre-mounted on the purlin 130 under the action of the fastener and the elastic member 160. By the spring giving the pressing block 120 and the purlin 130 a force to move away from each other, a large clamping space is provided between the two, which is convenient for the frame 110 to slide in and reduces the installation difficulty; after sliding in, the locking member 150 sleeved on the connecting member 140 is locked, so that the pressing block 120 and the purlin 130 firmly abut against the upper and lower sides of the frame 110, ensuring the anti-load performance of the photovoltaic module.

[0044] In other embodiments, two ends of the elastic member 160 are fixedly connected to the pressing block 120 and the purlin 130 respectively. When the pressing block 120 is pre-mounted on the purlin 130, the clamping space between them is smaller than the thickness of the frame 110. When the frame 110 needs to be placed, the pressing block 120 is lifted upward so that the frame 110 can be placed. That is to say, when the frame 110 is clamped between the pressing block 120 and the purlin 130, the elastic member 160 is in a stretched state, and thus can provide a force to drive one of the pressing block 120 and the purlin 130 to approach the other, that is, the spring can provide a certain locking force to the frame 110, reducing the possibility of displacement of the photovoltaic module.

[0045] As Figure 1 , Figure 6 and Figure 8 shown, in some embodiments, one end of the pressing block 120 is provided with a first crimping end 123, and one end of the purlin 130 is provided with a second crimping end 132. The two opposite end faces of the frame 110 are fixed by the first crimping end 123 and the second crimping end 132, and then the photovoltaic laminate 300 is fixed by the frame 110.

[0046] As Figure 4 and Figure 7 shown, in another embodiment, the pressing block 120 includes two first crimping ends 123. The arrangement directions of the two first crimping ends 123 are perpendicular to the first direction, and the two first crimping ends 123 are respectively used for abutting against the first end faces of two adjacent frames 110; the purlin 130 includes two second crimping ends 132. The arrangement directions of the two second crimping ends 132 are perpendicular to the first direction, and the two second crimping ends 132 are respectively used for abutting against the second end faces of two adjacent frames 110; the second end face and the first end face are distributed along the first direction. With this arrangement, one photovoltaic module mounting structure 100 can fix two sets of photovoltaic laminates 300 at the same time, and the installation efficiency is higher.

[0047] As Figure 4 shown, in one of the embodiments, the pressing block 120 protrudes towards the purlin 130 with a first abutting portion 124, and the first abutting portion 124 is used for abutting against the side surface of the frame 110; further, the purlin 130 protrudes towards the pressing block 120 with a second abutting portion 133, and the second abutting portion 133 is used for abutting against the side surface of the frame 110. Through the first abutting portion 124 and the second abutting portion 133, the limiting effect on the frame 110 is further improved, and then the installation reliability of the photovoltaic laminate 300 installed on the frame 110 is ensured, its anti-load performance is improved, and then its use reliability is improved.

[0048] Further, as Figure 1As shown in the figure, an embodiment of the present application further provides a photovoltaic system, including the photovoltaic module mounting structure 100 as described above and a photovoltaic laminate 300 mounted on the photovoltaic module mounting structure 100. During the installation process, there is no need to flip the pressing block 120 or the purlin 130, which not only improves the installation convenience and installation efficiency of the photovoltaic module, but also resists the loads on the light-receiving surface and the backlight surface of the photovoltaic module by the pressing block 120 and the purlin 130 respectively abutting against both sides of the frame 110 along the first direction, thereby improving its load resistance and other capabilities and ensuring its installation reliability.

[0049] As Figure 1 shown, in an actual application scenario, when the photovoltaic system is set on the ground, the photovoltaic system further includes a bracket 220 and a counterweight 210. One end of the bracket 220 is connected to the photovoltaic module mounting structure 100, and the other end of the bracket 220 is fixedly connected with a counterweight 210. Through the limitation of the counterweight 210 and the bracket 220, the possibility of displacement of the photovoltaic laminate 300 is reduced.

[0050] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0051] The above-described embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
