Description

[Technical field]

[0001] The present invention relates mainly to mounting parts for photovoltaic assemblies, and more particularly to a profile, a profile support part for connecting and fixing the profile, a photovoltaic assembly frame, a photovoltaic system and an assembly method thereof. [Background technology]

[0002] A profile is an object with a certain geometric shape obtained by manufacturing a material with a certain strength and toughness through processes such as rolling, extrusion, and casting. Due to the constraints of the manufacturing process, the cross-sectional shape of a profile is generally constant, and its shape and thickness are uniform in each cross section in the longitudinal direction. When selecting a profile, a profile that is suitable in terms of shape, material, mechanical performance, etc. is generally selected based on the actual installation needs. In actual application scenarios, the external forces received at different positions of the profile are not the same, so deformation and tearing are likely to occur at some positions of the profile. In order to avoid such deformation and tearing, the conventional technology generally adopts a design to reinforce the entire profile, such as thickening the entire profile, which leads to a certain amount of resource waste.

[0003] Profiles are used to form various frames, which are attached to the periphery of the workpieces and serve to support, secure and protect the corresponding workpieces.

[0004] In a specific application scenario, a photovoltaic assembly utilizes a photovoltaic assembly frame to fix the stacked components surrounding the solar cells. The assembly frame enhances the mechanical strength of the assembly, seals the edges of the stacked components, and fixes the stacked components to brackets to form a photovoltaic assembly (also referred to as photovoltaic assembly or assembly for short). Therefore, the strength of the assembly frame determines the overall strength of the photovoltaic assembly.

[0005] Existing photovoltaic assembly frames generally use aluminum alloy profiles for the main body and are integrally formed by extrusion. For the reasons mentioned above, the same type of frame profiles have uniform cross-sectional shapes and thickness dimensions, and the long and short sides of the assembly frame may differ, but the long and short sides are uniform. In many cases, the long and short sides are also uniform. As a result, when designing the strength of the assembly frame, it is necessary to design based on the part that receives the greatest force so that the entire frame meets the strength requirements of the part that receives the greatest force, which results in strength redundancy in other parts of the frame and ultimately leads to cost waste.

[0006] FIG. 1 shows a cross-sectional view of a profile, and FIG. 2 and FIG. 3 show schematic diagrams of the profile for assembling a photovoltaic assembly. As shown in the figures, the profile 11 has an A surface, a B1 surface, a B2 surface, a C surface, and a D surface. A notch 12 for mounting a photovoltaic assembly 20 is formed between the A surface and the D surface, a cavity 13 is formed between the B1 surface, the B2 surface, the C surface, and the D surface. The C surface is a bottom surface of the cavity 13, and the C surface extends inward to form the C2 surface. The C surface is a contact surface that contacts the photovoltaic bracket 30 when the photovoltaic assembly 20 is attached. Generally, the C2 surface has a screw hole 14 that is used to attach the photovoltaic assembly 20 to the bracket 30 in accordance with a fastener (not shown). More often, the A surface and the B1 surface are attached to the bracket 30 by a press block 40 and a fastener. In terms of the cost combination of conventional profile materials, the B1, B2 and C2 surfaces constitute the major part of the profile material cost.

[0007] FIG. 3 shows a schematic diagram of the purlins of the photovoltaic assembly mounted on the photovoltaic bracket. As shown in FIG. 3, when mounting the photovoltaic assembly 20, the long side section 11 of the assembly frame 10 is mounted perpendicularly to the purlins 31 of the bracket 30. The width of the purlins 31 is generally 40mm-60mm, and the positions of the two purlins 31 are generally in the region of 1 / 8-1 / 4 of the long side of the assembly. When the photovoltaic assembly 20 is subjected to a force, the stress of the assembly frame is maximum in this region (i.e., the position where the assembly frame and the purlins contact and the position nearby), while the stress is relatively small in other parts of the assembly frame. In the prior art, the design of the mechanical performance of the frame when designing the frame is performed with reference to the part with the highest stress, so that a load redundancy corresponding to the part with the lower stress is formed.

[0008] In addition, in the mounting method of the bolt hole in the prior art, the mounting position is generally located on the extension surface (i.e., C2 surface) in the bottom of the frame. In response to the need to reduce the cost of photovoltaic assemblies in recent years, the thickness and width of the C2 surface have been reduced as much as possible, which reduces the strength of the mounting surface of the assembly, and the bolt holes are often deformed or pulled out under force, resulting in failure. This technical problem can be solved by increasing the thickness of the bottom of the frame or widening the bottom surface of the frame. However, in the conventional assembly frame configuration, it is necessary to uniformly reinforce all the longitudinal directions of the long sides, or at least widen the C2 surface, which will significantly increase the cost and bring about a large economic burden.

[0093] In order to more clearly describe the technical solutions of the embodiments of the present application, the drawings that need to be used in the description of the embodiments will be briefly described. Obviously, the drawings in the following description are only some examples or embodiments of the present application, and those skilled in the art can also apply the present application to other similar scenarios based on these drawings without paying creative labor. Unless otherwise clear from the language environment or otherwise described, the same symbols in the drawings represent the same structures or operations.

[0094] As used herein and in the claims, terms such as "a," "one," "a kind," and / or "the" specifically include the plural rather than the singular, unless the context expressly indicates otherwise. In general, the terms "comprising" and "including" only indicate the inclusion of explicitly identified steps and elements, and do not constitute an exclusive list of those steps and elements, and a method or apparatus may include other steps or elements.

[0095] Unless otherwise shown, the relative arrangement of components and steps, mathematical expressions and numerical values ​​described in these examples are not intended to limit the scope of the present application. It should also be understood that for ease of explanation, the dimensions of each part shown in the drawings are not drawn based on actual proportional relationships. Techniques, methods and devices known to those of ordinary skill in the art may not be discussed in detail, but where appropriate, the techniques, methods and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be construed as merely illustrative, not limiting. Thus, other examples of the exemplary embodiments may have different values. Note that similar symbols and alphabets represent similar terms in the following figures, so that once a term is defined in one figure, it is not necessary to further discuss it in the following figures.

[0096] In the description of this application, the orientations or positional relationships indicated by directional terms (such as "front, back, top, bottom, left, right," "side, length, vertical, level," "ceiling, bottom," etc.) are generally orientations or positional relationships based on the drawings, and are merely for the purpose of facilitating and simplifying the description of this application. Unless otherwise stated, these directional terms do not indicate or imply that a specified device or element must have a particular orientation or be configured and operated in a particular orientation, and therefore should not be understood as a limitation on the scope of protection of this application. The directional terms "inside, outside" refer to the inside and outside of the contour of each part itself.

[0097] For ease of description, spatially relative terms such as "on," "above," "on top of," "above" and "on top of" may be used herein to describe the spatial location of one device or feature relative to another device or feature as shown in the figures. It should be understood that the spatially relative terms are intended to include different orientations of the device during use or operation other than the orientation described in the figures. For example, if a device in the drawings is turned upside down, it may be described as being "above other devices or structures" or "on top of other devices or structures" and then positioned as being "below other devices or structures" or "under other devices or structures." Thus, the exemplary term "above" can include two orientations: "above" and "below." The device may be positioned in other different ways (rotated 90 degrees or at other orientations) and the spatially relative descriptions used herein can be interpreted appropriately.

[0098] In addition, the use of terms such as "first" and "second" to limit the components is merely for the purpose of making it easier to distinguish the relevant components, and unless otherwise stated, the above terms have no special meaning and cannot be understood as limiting the scope of protection of the present application. Furthermore, although the terms used in the present application are selected from known common terms, some of the terms mentioned in the present application may be selected by the applicant according to his or her judgment, and the detailed meanings thereof will be explained in the relevant parts described in this specification. Furthermore, it is required to understand the present application through the meaning contained in each term as well as the actual terms used.

[0099] When a part is referred to as being "on another part," "connected to another part," or "in contact with another part," it should be understood that it may be directly on, directly connected to, or in direct contact with another part, or an intervening part may be present. In contrast, when a part is referred to as being "on another part," "connected directly to," or "in direct contact with," no intervening part is present.

[0100] The embodiment of the present application describes a profile clamping part and a profile. The profile clamping part is used to connect and fix a profile, and has a side groove on the side of the profile. One side of the profile clamping part has a first connecting part for connecting the side groove of one profile, and the other opposite side of the profile clamping part has a second connecting part for connecting the side groove of another profile. The profile clamping part has a fastening hole passing through it. When the profile clamping part is attached to a bracket of a photovoltaic assembly, a fastener can pass through the fastening hole to fix the profile clamping part.

[0101] A first convex rib is provided at the upper end of the notch in the gutter of the shaped member. Each of the first and second connecting portions of the shaped member pressing part has a first side and a second and third side respectively connected to both ends of the first side. A first protrusion is provided at the connection point between the first and second sides. When the shaped member pressing part is joined to the shaped member, the first protrusion passes over the first convex rib and engages with the ceiling surface of the gutter. Therefore, the shaped member pressing part and the shaped member can be easily assembled. Furthermore, the first convex rib can prevent the first convex portion from coming off the gutter.

[0102] The present embodiments are further described below with reference to the drawings.

[0103] [First embodiment] FIG. 4A is a perspective view of a profile used in a photovoltaic assembly frame in a first embodiment of the present application. FIG. 4B is a cross-sectional view of a profile used in a photovoltaic assembly frame in a first embodiment of the present application. FIG. 5A is a perspective view of a profile holder part in a first embodiment of the present application. FIG. 5B is a cross-sectional view of a profile holder part in a first embodiment of the present application. As shown with reference to FIGS. 4A to 5B, in one embodiment of the present invention, a profile holder part 200a for connecting and fixing a profile 100a is provided. The profile 100a includes an outer frame 110 having a cavity 111 therein and a groove 112 on a side surface for mounting a profile holder part, and a mounting part 120 located on the outer frame 110 for mounting a workpiece to be mounted. In some embodiments of the present application, the workpiece to be mounted is a photovoltaic assembly. The profile holder part 200a has a first connecting portion 220 on one side thereof for connecting the side groove 112 of the profile 100a, and a second connecting portion 230 on the opposite side thereof for connecting the side groove 112 of another profile 100a of the same shape, and the profile holder part 200a has a fastening hole 210 passing therethrough. Specifically, in this embodiment, the fastening hole 210 is located in the center of the profile holder part 200a.

[0104] Furthermore, as shown in FIG. 4A to FIG. 5B, in some embodiments of the present invention, the first convex 113 and the second convex 114 are provided at the upper and lower ends of the notch of the side gutter 112, respectively. In this embodiment, the side gutter 112 is located on the right side surface of the shaped member 100a, and the first convex 113 and the second convex 114 face each other vertically. Each of the first joint 220 and the second joint 230 includes a first side 241, and a second side 242 and a third side 243 connected to both ends of the first side 241, respectively. Here, the second side and the third side of the first joint 220 and the second joint 230 extend integrally. A first protrusion 251 is provided at the connection point between the first side 241 and the second side 242, and a second protrusion 252 is provided at the connection point between the first side 241 and the third side 243. When the profile retaining part 200a is joined to the profile 100a, the first protrusion 251 passes over the first ridge 113 and engages with the ceiling surface of the gutter 112, and the second protrusion 252 passes over the second ridge 114 and engages with the bottom surface of the gutter 112. As shown in Figures 4A to 5B, in this embodiment, the profile retaining part 200a is axially symmetrical. In Figures 5A to 5B, the first connecting portion 220 is the left portion of the profile retaining part 200a, and the second connecting portion 230 is the right portion of the profile retaining part 200a. In the figure, the left side of the profile holder part 200a is the first side 241 of the first connecting part 220, the right side of the profile holder part 200a is the first side 241 of the second connecting part 230, the left and right sides of the upper side of the profile holder part 200a are the first connecting part 220 and the second side 242 of the second connecting part 230, and the left and right sides of the lower side of the profile holder part 200a are the first connecting part 220 and the third side 243 of the second connecting part 230. In addition, the profile holder part 200a has one first protrusion 251 at each of the upper left corner and the upper right corner, and one second protrusion 252 at each of the lower left corner and the lower right corner.

[0105] In one embodiment, the lower end of the gutter notch is vertically aligned with the upper end of the notch, although it should be understood that this alignment is approximate with minor deviations being allowed, for example, the lower end of the notch may be recessed into the gutter relative to the upper end of the notch or extended toward the recessed gutter.

[0106] In the embodiment of the present application, the profile and profile clamping parts are specially designed so that the profile clamping parts can be inclined at a small angle, for example 10° to 20°, to the profile bottom surface 117, so that the profile can be inserted from the side into the side groove. Specifically, the end surface of the first convex strip 113 of the profile 100a is inclined upward from the inside to the outside. If the inclination angle of the end surface of the first convex strip 113 to the profile bottom surface 117 (which is located on a horizontal plane when the profile is placed horizontally) is α, the following condition is satisfied.

[0107]

number

[0108] Here, b is the thickness of the first convex rib 113, e is the height of the first convex rib 113, c is the depth of the gutter, and H is the notch width of the gutter (i.e., the distance between the lower end surface of the first convex rib 113 and the upper end surface of the second convex rib 114).

[0109] The end face of the second convex strip 114 of the gutter is inclined downward in the direction from the inside to the outside, and the inclination angle of the second convex strip 114 of the gutter with respect to the bottom surface 117 of the profile is β.

[0110] The ceiling surface of the gutter is inclined upward from the inside to the outside. If the inclination angle of the ceiling surface of the gutter with respect to the bottom surface 117 of the shaped member is γ, then

[0111]

number

[0112] When α and γ satisfy the above conditions, the profile holder part can be screwed into the profile groove at a small angle relative to the bottom surface 117 of the profile.

[0113] In some embodiments, the angles α, β and γ range from 10° to 20°, preferably from 15° to 18°.

[0114] In addition, it is preferable that the height of the first convex strip 113 is not too high so that the profile pressing part 200a is screwed into the side groove of the profile at a small angle to the profile. In addition, it is preferable that the height of the first convex strip 113 is not too low, otherwise the profile pressing part 200a is likely to come off from the side groove. For example, the height e of the first convex strip 113 is 2.5 mm to 3.5 mm. It is preferable that the height of the second convex strip 114 is not too high so that the profile pressing part 200a can be screwed into the side groove of the profile. In addition, it is preferable that the height of the second convex strip 114 is not too low, otherwise the profile pressing part 200a is likely to come off from the side groove. For example, the height f of the second convex strip 114 is 0.8 mm to 1.5 mm. Correspondingly, in the profile holder part 200a, the distance h between the end face of the first projection 251 and the end face of the second projection 252 is greater than the distance H from the end face of the first convex strip 113 of the side gutter 112 to the lower wall surface of the side gutter and smaller than H+e, and usually only needs to be slightly smaller. The second side 242 of the profile holder part 200a is inclined upward in the direction from the outside to the inside, and the inclination angle of the second side 242 of the profile holder part 200a with respect to the bottom surface 255 of the profile holder part (when the profile holder part 200a is laid flat, the profile bottom surface 255 is in a horizontal state) is θ. The third projection 253 has a slope facing the first projection 251, and the inclination angle of the slope with respect to the first side 241 (when the profile holder part 200a is laid flat, the first side 241 is in a vertical state) is δ. Here,

[0115]

number

[0116] Therefore, when the profile pressing part 200a is screwed into the side gutter, it is not hindered by the ceiling surface of the side gutter or the first convex rib.

[0117] It can be understood that when the profile and the profile holding part are fitted together, the space for accommodating a certain part should be slightly larger than this part. For example, the depth c of the side gutter 112 is slightly larger than the thickness C (left and right direction in the figure) of the first protrusion 251, the horizontal projection thickness of the first concave groove 261 is slightly larger than the thickness of the first convex strip 113, the depth c of the side gutter 112 is similarly slightly larger than the thickness (left and right direction in the figure) of the second protrusion 252, the horizontal projection thickness of the second concave groove 262 is slightly larger than the thickness of the second convex strip 114, the height E of the first protrusion 251 is slightly larger than the height e of the first convex strip 113, etc. If the vertical distance between the bottom surface of the second protrusion 252 and the bottom surface of the profile holding part is F, F is equal to or smaller than the vertical distance t between the bottom surface of the side gutter 112 and the bottom surface of the profile. In this manner, after the profile and the profile holding part are assembled, the second protrusion 252 can be pressed against the bottom surface of the side groove 113 .

[0118] In order to allow the profile retaining part 200a to be engaged with the side groove, the distance L between the outer end point A of the first groove 261 and the lower end B of the second protrusion 252 is equal to or less than the notch width H of the side groove. As described above, since the profile retaining part 200a in this embodiment has a symmetrical configuration, both of the first grooves 261 on both sides satisfy this condition, and are matched to profiles having the same configuration and parameters.

[0119] With this design, the profile holder 200a can be slightly tilted (see FIG. 7A), and when the first protrusion 251 is pressed into the side groove 112 beyond the first convex strip 113, the second edge 242 is aligned with the end face of the first convex strip 113, the profile holder 200a is screwed in a direction in which the bottom surface 255 of the profile holder 200a and the bottom surface 117 of the profile 100a are parallel, and the second protrusion 252 goes beyond the second convex strip 114 and enters the side groove 112. Since the aforementioned h is greater than H, the profile holder 200a cannot easily slide out of the side groove 112.

[0120] When the profile holder part 200a and the profile 100a are joined together, the clearance between the side surface of the profile holder part 200a (more specifically, the second side 242) and the side surface of the side groove 112 of the profile 100a is 2 mm or less. In one embodiment, the side surface of the side groove 112 may be provided with a lateral protrusion 116 that can limit the clearance between the side surface of the side groove 112 and the second side 242 of the profile holder part 200a.

[0121] It should be noted that the above-mentioned "both left and right sides" are merely an orientation concept proposed for ease of understanding, and do not mean that the left and right sides of the profile clamp part 200a are actually two separate parts.

[0122] Furthermore, in this embodiment, the second side 242 has a third protrusion 253 facing the first protrusion 251 with a gap therebetween, the third side 243 has a fourth protrusion 254 facing the second protrusion 252 with a gap therebetween, a first groove 261 for fitting to the first convex strip 113 is formed between the first protrusion 251 and the third protrusion 253, and a second groove 262 for fitting to the second convex strip 114 is formed between the second protrusion 252 and the fourth protrusion 254. Similarly, one third protrusion 253 is provided on each of the left and right sides of the upper side of the profile clamp part 200a in this embodiment, and one fourth protrusion 254 is provided on each of the left and right sides of the lower side of the profile clamp 200a. Furthermore, two first grooves 261 and two second grooves 262 are symmetrically present in the profile clamp part 200a in this embodiment. When the fourth protrusions 254 are present, the bottom surface 255 of the profile holder part is the end surface of the two fourth protrusions 254 (as in FIG. 5B). When the fourth protrusions 254 are not present, the bottom surface of the profile holder part is the surface between the two fourth protrusions 254 in FIG. 5B.

[0123] Fig. 4C shows a modified example of a profile used in the photovoltaic assembly frame in the first embodiment of the present application. As shown in Fig. 4C, the profile 100a' in this embodiment is different from that shown in Fig. 4A in that the groove surface of the side gutter 112 is flat and the lateral protrusion 116 in Fig. 4A is not provided.

[0124] 5C is a modified example of the profile holder part in the first embodiment of the present application. Referring to FIG. 5C, a first side 241 of the profile holder part has a protrusion 241a.

[0125] In one embodiment of the present application, a stiffener may be attached externally to one or more positions of the profile, as required. For example, as shown with reference to Figures 17A and 17B, the bottom of the outer frame 110 of profile 100c has an opening 115. The profile includes a stiffener 118 placed into the cavity 111 through the opening 115. The stiffener 118 may include a support portion 118a and a base 118b. The support portion 118a is integrally formed with the base 118b, perpendicularly intersecting the base 118b. In each embodiment, the support portion 118a forms a "king" shape, a "sun" shape (as shown in the figures), an "eye" shape, an inverted T shape, a frame shape, multiple frame shapes, a half frame shape, an O shape, a trapezoid, a square with a beveled bottom, a "chevron" shape, a "Z" shape, a "2" shape, an inverted "m" shape, a "u" shape, or an "n" shape in cross section.

[0126] FIG. 6A is a perspective configuration schematic diagram of an assembly method of a shape member and a shape-member holding part in the first embodiment of the present application, and FIG. 6B is a cross-sectional schematic diagram of the assembly method of the shape member and the shape-member holding part in the first embodiment of the present application. In conjunction with the above and what is shown with reference to Figures 6A to 6B, the assembly method of the profile 100a and the profile holding part 200a in this embodiment is, specifically, that two profile members 100a are fixed symmetrically to both sides of the profile holding part 200a, and the connection is completed by fixing and inserting the first protrusion 251 and the second protrusion 252 on both the left and right sides into the side grooves 112, and after the fixing is completed, the first groove 261 (see Figure 5A) consisting of the first protrusion 251 and the third protrusion 253 of the profile holding part 200a is attached to the first convex rib 113 of the profile 100a, and the second groove 262 (see Figure 5A) consisting of the second protrusion 252 and the fourth protrusion 254 of the profile holding part 200a is attached to the second convex rib 114 of the profile 100a. Furthermore, the fastener 211 fastens the two sections 100a attached to the left and right sides of the section holding part 200a to the bracket 400 through the fastener hole 210, thereby simultaneously fastening the two sections 100a attached to the left and right sides of the section holding part 200a. Specifically, in this embodiment, the fastener 211 includes a screw 211a and a nut 211b.

[0127] 7A to 7C are schematic diagrams of an assembly process of a profile and a profile holder part in the first embodiment of the present invention. As shown in FIG. 7A to FIG. 7C, a method of attaching the profile holder part 200a and the profile 100a in the above-mentioned embodiment is as follows.

[0128] (1) The first joint of the first profile clamping part is attached to the gutter of the profile having the photovoltaic assembly. As shown in FIG. 7A, four profile members 100a (two in the figure) are attached around the photovoltaic assembly 300a. First, the first profile clamping part 200a1 is attached to the gutter of one profile member 100a (the right side shown in FIG. 7A). The first profile clamping part 200a1 is screwed in at only a small angle (for example, 10° to 20° or 15° to 18°) to be engaged in the gutter 112. Then, the first profile clamping part 200a1 is screwed in until the bottom surface of the first profile clamping part 200a1 and the bottom surface of the profile are parallel.

[0129] (2) The side gutter of the profile having the first profile clamping part is engaged with the second joint of the second profile clamping part attached to the bracket by the fastener. As shown in Fig. 7B, the second profile clamping part 200a2 is fixed to the bracket 400 by the fastener 211. It is important to note that the second profile clamping part 200a2 should have a vertical movement of the height f of the second protrusion so that the fastener 211 is not tightened at this time and there is a certain space for the photovoltaic power generation assembly to be screwed into the profile on the other side and engaged in a predetermined position. The first convex strip 113 of the side gutter 112 of the profile 100a (left side shown in FIG. 7B) on the other side of the photovoltaic assembly 300 is aligned with the first concave groove 261 of the second profile retaining part 200a2 fixed to the bracket 400, and the assembly is screwed in at an angle of about 10° to 20° or 15° to 18°, so that the second convex strip 114 of the side gutter 112 of the profile 10 on the left side shown in the figure is engaged in the second concave groove 262 of the second profile retaining part 200a2. Then, the assembly is screwed in until the bottom surface of the profile and the second profile retaining part are parallel.

[0130] (3) The first member holding part is attached to the bracket by a fastener. As shown in Fig. 7C, the fastener 211 attached in step (2) (the left fastener 211 shown in Fig. 7C) is fastened, and the first member holding part 200a1 attached in step (1) is fixed to the bracket 400 by another fastener 211. Similarly, the fastener 211 is not fastened at this time, and the second member holding part 200a2 is given an amount of vertical movement of the height f of the second protrusion so that the other side member has a certain space to allow the photovoltaic power generation assembly to be screwed in and engaged in a predetermined position.

[0131] When each profile holder part and profile are joined together, the clearance between the side surface (more specifically, the first edge 241) of the profile holder part and the side surface of the side groove 112 of the profile is 2 mm or less.

[0132] After repeating the above steps (1) to (3), the installation of the multiple profile members 100a and the photovoltaic assemblies 300 can be completed.

[0133] Fig. 8 is a perspective schematic diagram of the installation of a photovoltaic assembly according to an embodiment of the present application. A part of a photovoltaic assembly frame (hiding the photovoltaic assembly and the horizontal profile) where installation is completed through the steps shown in Fig. 7A to Fig. 7C is as shown in Fig. 8. The photovoltaic assembly frame includes a plurality of profile holder parts 200a as described above, and a plurality of strip-shaped profiles 100a having a placement portion 120 (see Fig. 4A) for placing a workpiece waiting to be installed, and a side groove 112 to which at least one profile holder part 200a is attached on its side.

[0134] The plurality of profiles 100a substantially enclose an enclosed area for mounting a photovoltaic assembly.

[0135] Preferably, at least some of the multiple profile members 100a (such as the two profile members 100a on the left side of the figure) are arranged adjacent to each other, and the adjacent profile members 100a share a profile member holding part 200a.

[0136] In one embodiment of the present invention, the length of the profile clamp 200a is less than the length of the profile 100a in order to conserve material.

[0137] In one embodiment of the present invention, the profile clamping piece 200a is not a part of the photovoltaic assembly, but is a supporting structure that constitutes the photovoltaic assembly together with the bracket 400. The profile 100a in the photovoltaic assembly frame has a side groove, and the attachment between the photovoltaic assembly and the supporting structure is realized by connecting the side groove of the profile and the profile clamping piece, so the connection between the photovoltaic assembly and the supporting structure adopts a locking groove manner.

[0138] Please note that in the embodiment shown in Figure 8, there are four profile clamping parts 200a to which three profile members 100a are fixed, but the number of profile members 100a that can be attached during actual work is not limited to this, and the specific quantity is not limited here.

[0139] Second Example FIG. 9 is a schematic cross-sectional view of a profile used in a photovoltaic assembly frame in a second embodiment of the present application, and FIG. 10 is a schematic cross-sectional view of a profile pressing part in a second embodiment of the present application. As shown with reference to FIG. 9-FIG. 10, in one embodiment of the present invention, a first convex streak 113 is provided at the upper end of the notch of the side gutter 112 of the profile 100b, but the lower end 114a of the notch is flat. The first joint 220 and the second joint 230 of the profile pressing part 200b each include a first side 241, a second side 242 and a third side 243 respectively connected to both ends of the first side 241, and a first protrusion 251 is provided at the connection point between the first side 241 and the second side 242. The connection point 252' between the first side 241 and the third side 243 does not have a protrusion and is flat. When the profile retaining part 200b and the profile 100b are attached, the first protrusion 251 passes over the first convex strip 113 and is engaged with the ceiling surface of the gutter 112, and the third edge 243 slides directly into the gutter 112 and can be attached to the bottom surface of the gutter 112. Therefore, the profile retaining part in this embodiment is easier to attach than the first embodiment.

[0140] As shown in Figs. 9 and 10, the side groove 112 is located on the left side surface of the profile 100b. In this embodiment, the profile holder part 200b is axially symmetrical, the first joint part 220 is the left part of the profile holder part 200b, and the second joint part 230 is the right part of the profile holder part 200b. The left side of the profile holder part 200b in the figure is the first side 241 of the first joint part 220, the right side of the profile holder part 200b is the first side 241 of the second joint part 230, the left and right sides of the upper side of the profile holder part 200b are the first joint part 220 and the second side 242 of the second joint part 230, respectively, and the left and right sides of the lower side of the profile holder part 200b are the first joint part 220 and the third side 243 of the second joint part 230, respectively. The profile holder part 200b also has one first protrusion 251 at each of the upper left and upper right corners.

[0141] Since the second protrusion is not provided, the inclination angle of the end face of the first protrusion 113 with respect to the bottom surface 117 of the shaped member 100b is 0°, and the inclination angle of the ceiling surface of the gutter 112 with respect to the bottom surface 117 of the shaped member 100b is 0°. Correspondingly, the inclination angle of the upper surface of the inner second side 242 of the first protrusion 251 with respect to the bottom surface 255 of the shaped member is 0°.

[0142] It should be noted that the above-mentioned "left and right sides" are merely an orientation concept proposed for ease of understanding, and do not mean that the left and right sides of the profile holder part 200b are actually two separate parts.

[0143] Furthermore, in this embodiment, the second side 242 of the profile holder part 200b has a third protrusion 253 that faces the first protrusion 251 with a gap therebetween, and a first groove 261 for fitting, for example engaging, with the first protrusion 113 is formed between the first protrusion 251 and the third protrusion 253. A part of the upper surface of this second side 242 serves as the bottom surface of the groove. In addition, the third side 243 has a fourth protrusion 254 adjacent to the connection point 252'. When the profile holder part 200b and the profile 100b are joined together, the end surface of the fourth protrusion 254 is flush with the bottom surface of the profile 100b.

[0144] Other details of this embodiment that are similar to those of the first embodiment will be omitted.

[0145] Fig. 11 is a schematic cross-sectional view of an assembly method of a shaped member and a shaped member pressing part in a second embodiment of the present application. As described above and shown in Fig. 11, in the assembly method of the shaped member 100b and the shaped member pressing part 200b in this embodiment, specifically, two shaped members 100b are fixed symmetrically to both sides of the shaped member pressing part 200b, and the first protrusions 251 are fixed and inserted into the side grooves 112 on both the left and right sides to complete the connection, and after the fixing is completed, the first recessed groove 261 consisting of the first protrusion 251 and the third protrusion 253 of the shaped member pressing part 200b and the first convex strip 113 of the shaped member 100b are pasted together. Furthermore, the fastener 211 fixes the shaped member pressing part 200b to the bracket 400 through the fastening hole 210, thereby simultaneously fixing the two shaped members 100b attached to both the left and right sides of the shaped member pressing part 200b. Specifically, in this embodiment, the fastener 211 includes a screw 211a and a nut 211b.

[0146] 12A and 12B are schematic diagrams of an assembly process of a profile and a profile holder part in the second embodiment of the present invention. As shown in FIG. 12A and FIG. 12B, a method of attaching the profile holder part 200b and the profile 100b in the above-mentioned embodiment is as follows.

[0147] (1) As shown in FIG. 12A, first, a profile clamping part 200b is attached to one side of a first profile 100b in a solar power generation assembly frame (with a solar power generation assembly), and a first connecting portion of the profile clamping part 200b is screwed into the first profile 100b at only a small predetermined angle (for example, inclined at 10° to 20° or 15° to 18°) so as to engage into the side groove 112 of the profile 100b. Then, the profile clamping part 200b is further screwed in until the bottom surface of the profile clamping part 200b and the bottom surface of the first profile 100b become parallel.

[0148] (2) As shown in Fig. 12B, the profile clamping part 200b attached in step (1) is fixed to the bracket 400 by the fastener 211, and the fastener 211 is tightened. A second profile 100b of another photovoltaic power generation assembly frame is attached to the other side of the profile clamping part 200b (the right side shown in Fig. 12B), and the profile 100b is screwed in at a small angle (for example, 10° to 20° or 15° to 18°), so that the first convex strip 113 is engaged in the first concave groove 261, the lower notch of the side groove 112 is attached to the lower recess on the right side shown in the figure of the profile clamping part 200b, and the profile 100b is engaged with the second joint of the profile clamping part 200b, and then the profile 100b can be screwed in until the bottom surface of the profile clamping part 200b and the bottom surface of the profile clamping part 200b are parallel to each other.

[0149] When the profile holder part and each profile are joined together, the clearance between the side surface (more specifically, the first edge 242) of the profile holder part and the side surface of the side groove 112 of the profile is 2 mm or less.

[0150] After repeating the above steps (1) and (2), the installation of the multiple profiles 100b and the photovoltaic assemblies can be completed.

[0151] In one embodiment of the present invention, the profile clamping part 200b is not a part of the photovoltaic assembly frame, but is a supporting structure which constitutes the photovoltaic assembly together with the bracket 400. The profile 100b in the photovoltaic assembly frame has a side groove, and the attachment between the photovoltaic assembly and the supporting structure is realized by connecting the side groove of the profile and the profile clamping part, so the connection between the photovoltaic assembly and the supporting structure adopts a locking groove manner.

[0152] [Third embodiment] Fig. 13A is a perspective view of a profile pressing part with an elastic strip in the third embodiment of the present application, and Fig. 13B is a cross-sectional view of the profile pressing part with an elastic strip in the third embodiment of the present application. As shown in Figs. 4A to 5B and 13A to 13B, in one embodiment of the present invention, the upper and lower ends of the notch of the side groove 112 of the profile 100a have a first convex 113 and a second convex 114, and each of the first connecting part 220 and the second connecting part 230 has a first side 241 and a second side 242 and a third side 243 connected to both ends of the first side 241, among which a first protrusion 251 is provided at the connecting point between the first side 241 and the second side 242, and a second protrusion 252 is provided at the connecting point between the first side 241 and the third side 243 of the first connecting part 220. In addition, the height of the end face 252b of the second projection 252 of the second connecting part 230 relative to the bottom face 255 of the profile holding part is higher than the height of the end face 252a of the second projection 252 of the first connecting part 220 relative to the bottom face 255 of the profile holding part. When the profile holding part 200b and the two profile members 100a are connected to each other, the first projection 251 of the first connecting part 220 and the second connecting part 230 goes beyond the first convex strip 113 and is engaged with the ceiling surface of the gutter 112, the second projection 252 of the first connecting part 220 goes beyond the second convex strip 114 and is engaged with the bottom surface of the gutter 112, and the second projection 252 of the second connecting part goes beyond the second convex strip 114 and faces the bottom surface of the gutter 112 (see FIG. 14B).

[0153] In addition, an elastic strip 270 (the elastic strip is not shown in FIG. 13B ) is provided in the third groove 263 of the second connecting portion 230. When the second connecting portion of the profile holder part 200b is connected to the profile 100a, the elastic strip 270 of the second connecting portion 230 comes into contact with the second protrusion 114. In the embodiment of the present application, the elastic strip 270 is a rubber strip or a spring clip.

[0154] 13A to 13B, in this embodiment, the first connecting portion 220 is the left part of the profile holder part 200c, and the second connecting portion 230 is the right part of the profile holder part 200c. The left side of the profile holder part 200c in the figure is the first side 241 of the first connecting portion 220, the right side of the profile holder part 200c is the first side 241 of the second connecting portion 230, the left and right sides of the upper side of the profile holder part 200c are the first connecting portion 220 and the second side 242 of the second connecting portion 230, respectively, and the left and right sides of the lower side of the profile holder part 200c are the first connecting portion 220 and the third side 243 of the second connecting portion 230, respectively. Moreover, the profile retaining part 200c has one first protrusion 251 at each of the upper left corner and the upper right corner, one second protrusion 252 at the lower left corner, and one second protrusion 252 at the lower right corner. Since the height of the end face 252b of the second protrusion 252 of the second connecting part 230 relative to the bottom face 255 of the profile retaining part is higher than the height of the end face 252a of the second protrusion 252 of the first connecting part 220 relative to the bottom face 255 of the profile retaining part, the second connecting part 230 is more easily connected to the side gutter of the profile while maintaining fixation after connection.

[0155] The setting of various sizes of the first coupling part 220 may refer to the first embodiment. For example, the distance L between the outer end point A of the first groove 261 of the first coupling part and the lower end B of the second protrusion of the first coupling part is less than the notch width H of the side groove. The setting of the size of the second coupling part 230 is different from the above. In particular, the vertical distance L1 between the floating outer end point A' of the first groove 261 of the second coupling part 230 and the end face 252a of the second protrusion 252 of the second coupling part 230 is less than the notch width H of the side groove. This floating outer end point A' is the lowest point where the first groove 261 contacts the lower end point of the first protrusion of the profile 100a when the profile pressing part 200c is coupled to the profile 100a, and the floating outer end point A' is higher than the outer end point A. For example, the height difference e1 between the floating outer end point A' and the outer end point A is equal to the height f of the second protrusion 114. The vertical distance F from the end face 252a of the second projection of the second connecting portion 230 to the bottom face of the profile holder 200b is equal to or greater than the vertical distance (f+t) between the end face of the notch in the groove and the bottom face of the profile (see FIG. 4B). These designs allow the profile holder part 200c to be engaged in the groove of the profile.

[0156] In addition, by designing the relationship between L1 and H, even after the profile holding part 200b is attached by the fastener, another profile (described with reference to Figs. 15A to 15c below) can still be connected to the profile holding part 200b. In some embodiments, a chamfer is designed at the position P where the profile 100a (see Fig. 15C) contacts the bracket at the lower left corner, thereby lowering the height to which the profile 100a is passively lifted during installation, thereby lowering the height of the floating outer end point A'. Of course, as in the first embodiment, if the fastener 211 is not tightened during installation and the profile holding part is given an amount of vertical movement of the height f of the second protrusion, the second connecting part 230 only needs to satisfy the relationship between L and H. Other details of this embodiment that are similar to those of the first embodiment will be omitted.

[0157] In addition, the above-mentioned "both left and right sides" is merely a concept of orientation proposed for easy understanding, and does not mean that the left and right sides of the profile pressing part 200c are actually two separate parts. In addition, the elastic strip in this embodiment serves to provide frictional force, and its material is, for example, rubber, but is not particularly limited in this application.

[0158] Furthermore, in this embodiment, the second side 242 has a third protrusion 253 facing the first protrusion 251 with a gap therebetween, and the third side 243 of the second coupling portion has a fourth protrusion 254 facing the second protrusion 252 with a gap therebetween. A first groove 261 for fitting to the first convex strip 113 is formed between the first protrusion 251 and the third protrusion 253. A second groove 262 for fitting to (e.g., engaging with) the second convex strip 114 is formed between the second protrusion 252 and the third side 243 of the first coupling portion 220, and a third groove 263 for fitting to (e.g., engaging with) the second convex strip 114 is formed between the second protrusion 252 and the fourth protrusion 254 of the second coupling portion.

[0159] Fig. 14A is a perspective view of the assembly method of the profile with a side groove and the profile holding part with an elastic strip in the third embodiment of the present application, and Fig. 14B is a cross-sectional view of the assembly method of the profile with a side groove and the profile holding part with an elastic strip in the third embodiment of the present application. As shown in Figs. 13A to 14B, the assembly method of the profile 100a and the profile holding part 200c in this embodiment is specifically such that two profile 100a are fixed on both sides of the profile holding part 200c, and the connection is completed by fixing the first protrusion 251 and the second protrusion 252 to the side groove 112 on the left side, and the connection is completed by fixing the first protrusion 251 to the side groove 112 and contacting the second convex strip 114 of the side groove 112 with the elastic strip 270 on the right side. When the fixing is completed, the first groove 261 consisting of the first protrusion 251 and the third protrusion 253 of the profile holder 200c is attached to the first convex strip 113 of the profile 100a, the second groove 262 consisting of the second protrusion 252 and the fourth protrusion 254 of the first joint 220 of the profile holder 200c is attached to the second convex strip 114 of the profile 100a, and the elastic strip 270 of the second joint 230 of the profile holder 200c is attached to the second convex strip 114 of the profile 100. Furthermore, the fastener 211 fixes the profile holder 200c to the bracket 400 through the fastening hole 210, thereby simultaneously fixing the two profile 100a attached to the left and right sides of the profile holder 200c. Specifically, in this embodiment, the fastener 211 includes a screw 211a and a nut 211b.

[0160] 15A to 15C are schematic diagrams showing the assembly process of the profile and the profile holder with the elastic strip in the third embodiment of the present application. As shown in FIG. 15A to FIG. 15C, the method of attaching the profile holder 200c and the profile 100a in the above-mentioned embodiment is as follows.

[0161] (1) The first joint of the first profile clamping part is attached to the gutter of the profile having the photovoltaic assembly. As shown in FIG. 15A, two profile members 100a are attached to the left and right sides of the photovoltaic assembly 300. First, the first profile clamping part 200c1 is attached to the gutter of one profile member 100a (the right side shown in FIG. 15A). The profile clamping part 200c1 is screwed in at only a small angle (for example, 10° to 20° or 15° to 18°) to be engaged in the gutter 112. Then, the first profile clamping part 200c1 is screwed in until the bottom surface of the first profile clamping part 200c1 and the bottom surface of the profile member 100a are parallel to each other.

[0162] (2) The side gutter of the profile having the first profile holding part is engaged with the second joint of the second profile holding part attached to the bracket by the fastener. As shown in FIG. 15B, the profile holding part 200c2 is fixed to the bracket 400 by the fastener 211, and the fastener 211 is fastened. The first convex strip 113 of the side gutter 112 of the profile 100a (left side shown in FIG. 15B) on the other side of the photovoltaic assembly 300 is aligned with the first concave groove 261 of the second profile holding part 200c2 fixed to the bracket 400, and the photovoltaic assembly 300 is screwed in at about 10° to 20° or 15° to 18°, so that the second convex strip 114 of the side gutter 112 of the profile 100c on the left side shown in the figure comes into contact with the elastic strip 270 of the second profile holding part 200c2. Thereafter, the assembly 300 is screwed in until the bottom surface of the profile 100c and the second profile holding part 200c2 are parallel to each other.

[0163] (3) The first member retaining part 200c1 is attached to the bracket by a fastener. As shown in Fig. 15C, the member retaining part 200c1 attached in step (1) is fixed to the bracket 400 by a fastener 211, and the fastener 211 is fastened.

[0164] When each profile holder part and profile are joined together, the clearance between the side surface (more specifically, the first edge 241) of the profile holder part and the side surface of the side groove 112 of the profile is 2 mm or less.

[0165] After repeating the above steps (1) to (3), the installation of the multiple profiles and photovoltaic assemblies 300 can be completed.

[0166] In one embodiment of the present invention, the profile clamping parts 200c1, 200c2 are not part of the photovoltaic assembly frame, but are supporting structures that constitute the photovoltaic assembly together with the bracket 400. The profile 100a in the photovoltaic assembly frame has a side groove, and the attachment between the photovoltaic assembly and the supporting structure is realized by connecting the side groove of the profile and the profile clamping parts, so the connection between the photovoltaic assembly and the supporting structure adopts a locking groove manner.

[0167] [Fourth embodiment] Fig. 16A is a schematic diagram of the configuration of one of the shapes in the fourth embodiment of the present application. Fig. 16B is a schematic diagram of the assembly of the shape and the shape pressing part in the fourth embodiment of the present application. As shown with reference to Figs. 16A to 16B, in one embodiment of the present invention, the end face of the first convex strip 113 of the side gutter 112 of the shape 100c is horizontal, that is, the above-mentioned α=0°. Correspondingly, the ceiling surface of the side gutter 112 is horizontal, that is, γ=0°.

[0168] In this design, the design of size parameters is easier. The profile clamping part for this embodiment is similar to that of FIG. 5B in the first embodiment. When the profile 100c and the profile clamping part 200a are mated, the space for accommodating a certain part should be slightly larger than this part. For example, referring to FIG. 16A and FIG. 5B, the depth c of the side groove 112 is slightly larger than the thickness C (left and right direction in the figure) of the first protrusion 251, the horizontal projection thickness of the first concave groove 261 is slightly larger than the thickness b of the first convex strip 113, the depth c of the side groove 112 is similarly slightly larger than the thickness (left and right direction in the figure) of the second protrusion 252, the horizontal projection thickness of the second concave groove 262 is slightly larger than the thickness of the second convex strip 114, the height E of the first protrusion 251 is slightly larger than the height e of the first convex strip 113, etc. If the vertical distance between the end face of the second protrusion 252 and the bottom surface 255 of the profile holder 200a is F, F is equal to or less than the vertical distance t between the bottom surface of the gutter 112 and the profile bottom surface 177. In this way, after the profile 100c and the profile holder 200a are assembled, the second protrusion 252 can be pressed against the bottom surface of the gutter 112.

[0169] In order to allow the profile retaining part 200a to be engaged with the side groove, the distance L between the outer end point A of the first groove 261 and the lower end B of the second protrusion 252 is equal to or less than the notch width H of the side groove. As described above, since the profile retaining part 200a in this embodiment has a symmetrical configuration, the first grooves 261 on both sides both satisfy this condition and are matched to profile members having the same configuration and parameters.

[0170] Other details of this embodiment that are similar to those of the first embodiment will be omitted.
