Description

Technical Field

[0001] This utility model relates to installation components for photovoltaic modules, specifically to a profile pressing component. Background Technology

[0002] Patent publication CN115589189A, entitled "Profile Pressing Component, Profile, Photovoltaic Module Frame, Photovoltaic System and Assembly Method Thereof," discloses a profile and a profile pressing component. The profile has a side groove, with a first protrusion at the upper end of the groove opening and a second protrusion at the lower end. The profile pressing component is integrally formed and has a first protrusion and a second protrusion. The first protrusion can extend beyond the first protrusion and engage with the top of the side groove, and the second protrusion can extend beyond the second protrusion and engage with the bottom of the side groove, thereby enabling rapid installation of the photovoltaic module.

[0003] However, because the profile fittings are integrally molded, after multiple rows or columns of photovoltaic modules are installed, the profiles and fittings in the middle section cannot be separated, making disassembly and replacement inconvenient. The reason for this inability to separate is that the first and second protrusions of the profile fitting are stuck in the side grooves of the profile, preventing the side grooves from disengaging from the profile fitting. If a photovoltaic module in the middle section malfunctions, it is necessary to disassemble the photovoltaic modules one by one from the outside in.

[0004] Therefore, there is an urgent need for a simple and flexible profile pressing component that is inexpensive and quick to disassemble, in order to reduce the difficulty of photovoltaic module maintenance and improve the maintenance efficiency of photovoltaic modules. Utility Model Content

[0118] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0119] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein, and therefore the present invention is not limited to the specific embodiments disclosed below.

[0120] As indicated in this application and claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" are not specifically singular and may include plural forms.

[0121] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0122] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application. In addition, although the terminology used in this application is selected from commonly known and used terms, some terms mentioned in this application's specification may have been chosen by the applicant according to his or her judgment, and their detailed meanings are explained in the relevant sections of this description. Moreover, this application should be understood not only through the actual terms used, but also through the meaning implied by each term.

Figure 1C A perspective view of another profile 100a' provided for this application. (See attached image.) Figures 1A-1C As shown, one side of the profile 100a has a side groove 120, which has a first opening 130 that opens downwards and a second opening 140 that opens upwards. The other side of the profile 100a has an outer frame 110 and a clamping portion 160. The outer frame 110 has a hollow chamber 111 inside. The clamping portion 160 is located above the outer frame 110 and has a certain degree of elasticity for clamping photovoltaic modules (not shown). In some embodiments, the side of the side groove 120 also has a lateral protrusion 121. Figure 1C For example, this application provides a variation of a profile 100a used in a photovoltaic module frame. (Refer to...) Figure 1C As shown, profile 100a' and Figure 1A The difference shown is that the groove surface of the side groove 120 is flat, without the following characteristics: Figure 1A Lateral protrusion 121 in the middle. Profiles 100a and 100a' are used to engage with the profile pressing parts provided in this application, and the profile pressing parts are used to fix the profiles 100a and 100a'.

[0126] Figure 2 This is a perspective view of a profile pressing member 200a according to an embodiment of this application. Figure 3 This is a perspective view of the upper pressing part 210 of the profile pressing part 200a. Figure 4 This is a 3D view of its lower pressing component. Figure 5 This is a cross-sectional view of profile pressing part 200a. Figure 6 Here is a cross-sectional view of the upper pressure member 210. Figure 7 This is a cross-sectional view of its pressing component 220. (See diagram below.) Figures 2-7As shown, this application provides a profile pressing member 200a for connecting and fixing a profile 100a. The profile pressing member 200a includes an upper pressing member 210 and a lower pressing member 220, which are configured for detachable engagement. The upper pressing member 210 includes a first side 217 and a second side 218. The first side 217 is provided with a first engagement groove 280, and the second side 218 is provided with a second engagement groove 281. The lower pressing member 220 includes a third side 227 and a fourth side 228. The third side 227 is provided with a first protrusion 282, and the fourth side 228 is provided with a second protrusion 283. When the upper pressing member 210 and the lower pressing member 220 are used together, the first protrusion 282 engages with the first engagement groove 280, and the second protrusion 283 engages with the second engagement groove 281. In some embodiments, the first side 217 and the third side 227 are on the same plane, and the second side 218 and the fourth side 228 are on the same horizontal plane. Placing the first side 217 and the third side 227 on the same plane makes the assembly and disassembly process smoother and reduces extra work caused by alignment issues. Furthermore, no uneven gaps are formed between the sides of the upper pressure member 210 and the lower pressure member 220, which is beneficial for the connection between the upper pressure member 210, the lower pressure member 220 and the profile 100a. From an aesthetic point of view, its shape is more natural and beautiful.

[0127] In some embodiments, the first protrusion 282 and the first engaging groove 280, as well as the second protrusion 283 and the second engaging groove 281, can move relatively back and forth along a first direction x under the action of an external force. For example... Figure 8 As shown, when the upper pressure member 210 is subjected to an external pushing or pulling force, it can move relative to the lower pressure member 220 along the first direction x. After moving a certain distance, the first protrusion 282 and the first engaging groove 280 disengage, as do the second protrusion 283 and the second engaging groove 281. In another case, for example, when the lower pressure member 220 is subjected to an external pushing or pulling force, it can move relative to the upper pressure member 210 along the first direction x. After moving a certain distance, the first protrusion 282 and the first engaging groove 280 disengage, as do the second protrusion 283 and the second engaging groove 281. However, the engaged first protrusion 282 and the first engaging groove 280, as well as the engaged second protrusion 283 and the second engaging groove 281, cannot move up and down along the second direction z under the action of external force.

[0128] like Figure 8As shown, the profile pressing member 200a is configured as an upper pressing member 210 and a lower pressing member 220, which can be moved relative to each other. During disassembly, the upper pressing member 210 and the lower pressing member 220 can be separated, and then the upper pressing member 210 and the lower pressing member 220 can be pulled out from the profiles 100a on both sides respectively. After the profile 100a is no longer engaged with the profile pressing member 200a, disassembly and maintenance can be achieved, which facilitates the disassembly and maintenance of the photovoltaic module 300 in the middle position after installing multiple rows of photovoltaic modules 300.

[0129] See also Figure 2 and Figure 4 As shown, in some embodiments, the upper pressure member 210 and the lower pressure member 220 have through fastening holes 230, which can be fastened by fasteners 231 (see reference). Figure 10 The fastener 231 penetrates and fixes the upper pressure member 210 and the lower pressure member 220 to the bracket 400. When the upper pressure member 210 and the lower pressure member 220 are fixed by the fastener 231, the upper pressure member 210 and the lower pressure member 220 cannot move relative to each other or separate under external force. Under the action of the fastener 231, a more stable connection between the upper pressure member 210 and the lower pressure member 220 can be achieved.

[0130] Continue to refer to Figures 2-7 In some embodiments, the first engaging slot 280 and the second engaging slot 281 are in the shape of an "S" or a "J", and the first protrusion 282 and the second protrusion 283 are in the shape of an inverted "L".

[0131] The shape, or "S" or "J" shape, can be understood as the approximate outline of the first engaging groove 280 and the second engaging groove 281 being "S" or "J" shaped. For example, the first engaging groove 280 can bend inward a certain distance along the third direction y, then extend downward a certain length along the second direction z, and then bend outward a certain distance along the third direction y. Here, "outward" refers to the outer side of the profile pressing member 200a, and "inward" refers to the inner side of the profile pressing member 200a. From the cross-sectional view and the connection of the first side 217 and the first engaging groove 280, its approximate outline is "S" shaped. Alternatively, the first engaging groove 280 can form a counter-clockwise rotating "J" shape, first extending inward a certain distance along the third direction y, and then forming a hook extending outward along the third direction y. Looking at the first side 217 and the first engaging groove 280, its approximate outline is a counter-clockwise rotating "J" shape. In some embodiments, the first coupling slot 280 and the second coupling slot 281 are axially symmetrical.

[0132] Similarly, the inverted "L" shape of the first protrusion 282 and the second protrusion 283 means that the general outline of the first protrusion 282 and the second protrusion 283 is "L" shaped. For example, the first protrusion 282 and the second protrusion 283 extend inward along a third direction y, and from the cross-sectional view and in conjunction with the third side 227 and the fourth side 228, the first protrusion 282 and the second protrusion 283 are "L" shaped. In some embodiments, the first protrusion 282 and the second protrusion 283 are axially symmetrical.

[0133] like Figures 2-6 and Figure 7 As shown, in some embodiments, the upper pressing member 210 further includes a first connecting portion 211 and a second connecting portion 212, and the lower pressing member 220 further includes a third connecting portion 221 and a fourth connecting portion 222. The first connecting portion 211 and the third connecting portion 221 are used to connect the side groove 120 of one profile 100a, and the second connecting portion 212 and the fourth connecting portion 222 are used to connect the side groove 120 of another profile 100a. The upper pressing member 210 also includes a first side 219, on which the first connecting portion 211 and the second connecting portion 212 are disposed. The first side 219 connects the first side 217 and the second side 218 and extends integrally. The first connecting portion 211 includes a first protrusion 213, which is disposed at the connection between the first side 217 and the first side 219, that is... Figure 5 The upper left corner of the upper pressure member 210 shown; the second joint 212 includes a second protrusion 214, which is located at the connection between the second side 218 and the first side 219, that is Figure 5 The upper right corner of the upper pressing member 210 shown. The first protrusion 213 is used to engage with the first opening 130 of the profile 100a when the profile pressing member 200a is combined with the profile 100a, and the second protrusion 214 is used to engage with the first opening 130 of another profile 100a when the profile pressing member 200a is combined with the profile pressing member 200a.

[0134] like Figures 2-7 As shown, in some embodiments, the pressing member 220 further includes a second side 229, a third connecting portion 221 and a fourth connecting portion 222 disposed on the second side 229, the second side 229 connecting the third side 227 and the fourth side 228 and extending integrally. The third connecting portion 221 further includes a third protrusion 223, the third protrusion 223 being located at the connection between the third side 227 and the second side 229, that is... Figure 5 The lower left corner of the pressing member 220 shown; the fourth joint 222 includes a fourth protrusion 224, which is located at the connection between the fourth side 228 and the second side 229, that is Figure 5The lower right corner of the pressing member 220 shown. The third protrusion 223 is used to engage with the second opening 140 of the profile 100a when the profile pressing member 200a is combined with the profile 100a; the fourth protrusion 224 is used to engage with the second opening 140 of another profile 100a when the profile pressing member 200a is combined with the profile pressing member 200a.

[0135] like Figure 1A As shown, in some embodiments, a downward-facing third protrusion 132 is provided on the right side of the first opening 130, and an upward-facing fourth protrusion 142 is provided on the right side of the second opening 140, with the third protrusion 132 and the fourth protrusion 142 facing each other vertically. A first protrusion 213 and a second protrusion 214 are used to pass over the third protrusion 132 and engage with the second opening 140, and a third protrusion 223 and a fourth protrusion 224 are used to pass over the fourth protrusion 142 and engage with the second opening 140.

[0136] In some embodiments, the first opening 130 of the side groove 120 is vertically aligned with the second opening 140. It is understood that this alignment is approximate, allowing for minor misalignment, such as allowing the first opening 130 to retract outward or extend inward relative to the second opening 140.

[0137] like Figures 2-7 In some embodiments, the first coupling portion 211 further includes a fifth protrusion 215 spaced apart from the first protrusion 213, and a first groove 240 is formed between the first protrusion 213 and the fifth protrusion 215; the second coupling portion 212 further includes a sixth protrusion 216 spaced apart from the second protrusion 214, and a second groove 250 is formed between the second protrusion 214 and the sixth protrusion 216; the first groove 240 and the second groove 250 are used to cooperate with the third protrusion 132. The first groove 240 and the second groove 250 are used to cooperate with the third protrusion 132 in the following ways: after the first protrusion 213 passes over the third protrusion 132 of a profile 100a and is engaged in the first opening 130 of the profile 100a, the third protrusion 132 of the profile 100a is engaged in the first groove 240; after the second protrusion 214 passes over the third protrusion 132 of another profile 100a and is engaged in the first opening 130 of the profile 100a, the third protrusion 132 of the profile 100a is engaged in the second groove 250.

[0138] like Figures 2-5 and Figure 7As shown, in some embodiments, the third connecting portion 221 further includes a seventh protrusion 225 spaced apart from the third protrusion 223, and a third groove 260 is formed between the third protrusion 223 and the seventh protrusion 225; the fourth connecting portion 222 further includes an eighth protrusion 226 spaced apart from the fourth protrusion 224, and a fourth groove 270 is formed between the fourth protrusion 224 and the eighth protrusion 226; the third groove 260 and the fourth groove 270 are used to engage with the fourth protrusion 142. The engagement of the third groove 260 and the fourth groove 270 with the fourth protrusion 142 means that after the third protrusion 223 passes over the fourth protrusion 142 of a profile 100a and is engaged in its second opening 140, its fourth protrusion 142 is engaged in the third groove 260; after the fourth protrusion 224 passes over the fourth protrusion 142 of another profile 100a and is engaged in its second opening 140, its fourth protrusion 142 is engaged in the fourth groove 270. By inserting the third protrusion 132 and the fourth protrusion 142 of the profile 100a into the first groove 240 and the second groove 250 respectively, and inserting the third protrusion 132 and the fourth protrusion 142 of the other profile 100a into the third groove 260 and the fourth groove 270 respectively, the connection between the profile 100a and the profile pressing part 200a can be made more secure, preventing the profile 100a from falling off during use.

[0139] In some embodiments, through a special design of the profile 100a and the profile clamping member 200a, the profile clamping member 200a can be tilted at a small angle relative to the bottom surface of the profile 100a, for example, 10-20°, so that it can be inserted into the side groove 120 of the profile 100a from the side. In some embodiments, the tilt angle can be 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, and 20°. Figure 1B As shown, assuming b is the thickness of the third protrusion 132, e is the height of the third protrusion 132, c is the depth of the side groove 120, and H is the width of the side groove 120 (the distance between the lower end face 133 of the third protrusion and the upper end face 143 of the fourth protrusion), the height of the third protrusion 132 of the profile 100a is between 2.5 and 3.5 mm, for example, it can be 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3, 3.4, and 3.5 mm. An excessively high third protrusion 132 will prevent the profile pressing part 200a from screwing into the side groove 120 of the profile 100a beyond the third protrusion 132. The height of the fourth protrusion 142 is 0.8-1.5 mm, for example, its height is 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4, and 1.5 mm. An excessively low fourth protrusion 142 can cause the profile pressing part 200a to easily detach from the side groove 120. For example... Figure 5As shown, in the profile pressing part 200a, the distance h between the first protruding end face 213a and the third protruding end face 223a is larger than the distance H from the end face of the third protrusion 132 to the end face of the fourth protrusion 142 of the side groove 120, and smaller than H+e. Usually, it only needs to be slightly smaller. The setting of the tilt angle, the width of H, the height of the third protrusion 132 and the fourth protrusion 142, and the related angles can be found in the invention patent with publication number CN115589189A.

[0140] See also Figure 1B and Figure 5 As shown, when profile 100a and profile pressing member 200a are used together, the space accommodating a certain part should be slightly larger than that part. For example, the depth c of the side groove 120 is slightly larger than the thickness C of the first protrusion 213 and the second protrusion 214; the projected thickness of the first groove 240 and the second groove 250 in the horizontal direction is slightly larger than the thickness of the third protrusion 132 and the fourth protrusion 142; the height E of the first protrusion 213 and the second protrusion 214 is slightly larger than the height e of the third protrusion 132 and the fourth protrusion 142, and so on. The vertical distance F between the end face 223a of the third protrusion and the bottom 285 of the lower pressing member is less than or equal to the vertical distance t between the bottom surface 141 of the second opening and the bottom surface 150 of the profile. With this arrangement, when profile pressing member 200a and profile 100a are used together, the third protrusion 223 and the fourth protrusion 224 can press against the bottom surface 141 of the second opening.

[0141] In addition, such as Figure 5 As shown, the distance L between the outer end point A of the first groove 240 and the lower end B of the third protrusion 223 is less than or equal to the width H of the side groove 120, so that the profile pressing member 200a can be inserted into the side groove 120. Because the profile pressing member 200a is axially symmetrical along its midline, the second groove 250 and the second protrusion 214 also satisfy this condition and cooperate with the profile 100a with the same structure and parameters.

[0142] With the above design, the profile pressing member 200a can be slightly tilted, allowing the first protrusion 213 to pass over the third protrusion 132 and be inserted into the side groove 120. At this time, the first side 219 mates with the end face 133 of the third protrusion, and the profile pressing member 200a rotates in a direction that makes the bottom 285 of the lower pressing member parallel to the bottom surface 150 of the profile. The third protrusion 223 passes over the fourth protrusion 142 and enters the side groove 120. Since the aforementioned h is greater than H, the profile pressing member 200a is not easy to slide out of the side groove 120.

[0143] Figure 9This is a variation of the profile pressing member 200a provided in this application. In this embodiment, the first side 217 and the third side 227 of the profile pressing member 200a' each have an expansion portion 284, which is used to abut against the side groove 120 of the profile 100a, making the connection between the profile 100a and the profile pressing member 200a' more stable.

[0144] Figure 10 This is a cross-sectional view of the assembly method of profile 100a and profile pressing member 200a' according to an embodiment of this application. Figure 11 This is a side view showing the assembly method of profile 100a and profile pressing member 200a' according to an embodiment of this application. (In conjunction with...) Figures 10-11 As described above, the upper pressing member 210 and the lower pressing member 220 cooperate to form a profile pressing member 200a', which together fixes two symmetrical profiles 100a. The clamping portion 160 of the profile 100a clamps the photovoltaic module 300. In some embodiments, the fastener 231 includes a screw 231a and a nut 231b. The screw 231a passes through the fastening holes 230 of the upper pressing member 210 and the lower pressing member 220, fixing the upper pressing member 210 and the lower pressing member 220 to the bracket 400. The third protrusion 132 of the left profile 100a is inserted into the first groove 240, with the first protrusion 213 abutting against the third protrusion 132. The fourth protrusion 142 is inserted into the third groove 260, with the second protrusion 214 abutting against the fourth protrusion 142. Similarly, the third protrusion 132 of the right profile 100a is inserted into the second groove 250, with the third protrusion 223 abutting against the third protrusion 132. The fourth protrusion 142 is inserted into the fourth groove 270, with the fourth protrusion 224 abutting against the fourth protrusion 142. The assembly steps can be found in the invention patent with publication number CN115589189A, and will not be detailed here.

[0145] like Figure 8 and Figures 12-13 As shown, when it is necessary to disassemble the mating connection between profile 100a and profile clamping member 200a' to maintain the photovoltaic module 300, the fastener 231 (not shown) can be removed first. For example, the nut 231b (not shown) and screw 231a (not shown) can be removed by tightening the nut 231b (not shown). Then, an external force, such as a pushing or pulling force, is applied to the upper clamping member 210 or the lower clamping member 220 to cause relative sliding and separation between the upper clamping member 210 and the lower clamping member 220. After the upper pressing member 210 and the lower pressing member 220 separate, they cannot fix the profile 100a, and the upper pressing member 210 cannot engage with the third protrusion 132 of the profile 100a, and the lower pressing member 220 cannot engage with the fourth protrusion 142 of the profile 100a. Therefore, the third protrusion 132 and the fourth protrusion 142 of the profile 100a do not prevent the upper pressing member 210 and the lower pressing member 220 from exiting the side groove 120 of the profile 100a. Figures 12-13As shown, the upper pressure member 210 is placed at the midpoint of the two profiles 100a along the second direction z, and then removed along the first direction x. The lower pressure member 220 is placed at the midpoint of the two profiles 100a along the second direction z, and then removed along the first direction x. This operation is repeated until the profile pressure member 200b connected to the left profile 100a and the profile pressure member 200b connected to the right profile 100a are separated. After this separation, the left photovoltaic module 300 and the right photovoltaic module 300 can be maintained or replaced.

[0146] like Figure 8 and Figures 14-15 As shown, another method for separating the upper pressure member 210 and the lower pressure member 220 is illustrated. First, fastener 231 (not shown) is removed. Then, an external force is applied to cause the upper pressure member 210 and the lower pressure member 220 to slide relative to each other and separate. After the upper pressure member 210 and the lower pressure member 220 separate, the upper pressure member 210 is deflected by a certain angle and then pulled away along the first direction x. The lower pressure member 220 is deflected by a certain angle and then pulled away along the first direction x.

[0147] Figure 16 This is a cross-sectional view of profile 100b according to another embodiment of this application. Figure 17 This is a cross-sectional view of profile pressing member 200b according to another embodiment of this application. Figure 18 This is a cross-sectional view showing the installation of profile 100b and profile clamp 200b according to another embodiment of this application. Figures 16-17 As shown, unlike the aforementioned profile, the bottom surface 141 of the second opening does not have a protrusion, and the bottom surface 141 of the second opening is flat.

[0148] like Figure 16 and Figure 17 As shown, with Figure 2 and Figure 9 Unlike the profile pressing component shown, the third joint 221 and fourth joint 222 of the lower pressing component 220 are flat instead of protruding. When the profile 100b is joined with the profile pressing component 200b, the lower pressing component 220 can slide directly into the bottom of the profile 100b without the need for a snap-fit ​​structure. This design facilitates the easy installation of the profile 100b and the profile pressing component 200b. The second side 229 of the lower pressing component 220 is provided with a seventh protrusion 225 and an eighth protrusion 226. When the profile pressing component 200b is joined with the profile 100b, the end faces of the seventh protrusion 225 and the eighth protrusion 226 are flush with the bottom surface 150 of the profile. Another difference is that the first protrusion 213, the second protrusion 214, the fifth protrusion 215, and the sixth protrusion 216 are all flat and do not have an inclined angle. Other structures and... Figure 2 and Figure 9The profile pressing components shown are similar and will not be described again here. The upper pressing component 210 and the lower pressing component 220 each have a fastening hole 230 (not shown). A fastener 231 (not shown) passes through the fastening holes 230 of the upper pressing component 210 and the lower pressing component 220, for mounting the upper pressing component 210 and the lower pressing component 220 onto the bracket 400. In this embodiment, the fastener 231 includes a screw 231a and a nut 231b.

[0149] Figure 18 This is an assembly cross-sectional view of profile 100b and profile pressing member 200b in this embodiment, as shown below. Figure 18 As shown, after the upper pressing member 210 and the lower pressing member 220 are engaged to form the profile pressing member 200b, the first protrusion 213 is engaged at the top of the first opening 130, and the third protrusion 132 is engaged in the first groove 240, fitting against the bottom of the first groove 240. The second protrusion 214 is engaged at the top 131 of the first opening of another profile 100b, and the third protrusion 132 of the other profile 100b is engaged in the second groove 250, fitting against the bottom of the second groove 250. The third connecting part 221 of the second side 229 fits against the bottom surface 141 of the second opening, and the fourth connecting part 222 fits against the bottom surface 141 of another second opening. The assembly steps can be referred to the invention patent with publication number CN115589189A, and the assembly steps are not described here.

[0150] Figures 19-20 This is a schematic diagram illustrating the disassembly of the profile 100b and the profile clamping member 200b according to an embodiment of this application, and also a schematic diagram illustrating the disassembly after the upper clamping member 210 and the lower clamping member 220 have been separated. As mentioned above, the upper clamping member 210 and the lower clamping member 220 can slide relative to each other and separate under the action of external force. The upper clamping member 210 is placed at the middle height position of the two profiles 100b along the second direction z, and then the upper clamping member 210 is pulled away along the first direction x. The lower clamping member 220 is placed at the middle height position of the two profiles 100b along the second direction z, and then the lower clamping member 220 is pulled away along the first direction x. This operation is repeated to separate the profile clamping member 200b connected to the left profile 100b and the profile clamping member 200b connected to the right profile 100b, after which the left photovoltaic module 300 and the right photovoltaic module 300 can be maintained or replaced.

[0151] like Figures 21-22 As shown, another method for separating the upper pressure member 210 and the lower pressure member 220 is illustrated. First, fastener 231 (not shown) is removed. Then, an external force is applied to cause the upper pressure member 210 and the lower pressure member 220 to slide relative to each other and separate. After the upper pressure member 210 and the lower pressure member 220 separate, the upper pressure member 210 is deflected by a certain angle and then pulled away along the first direction x. The lower pressure member 220 is deflected by a certain angle and then pulled away along the first direction x.

[0152] Figures 23-28 This is a profile pressing component according to another embodiment of this application. Figure 23 Its three-dimensional structure diagram, Figure 24 Its cross-sectional view, Figure 25 This is a three-dimensional structural diagram of the upper pressing component 210. Figure 26 This is a cross-sectional view of the upper pressure component 210. Figure 27 This is a three-dimensional schematic diagram of the pressing component 220. Figure 28 This is a cross-sectional view of the pressing member 220. (Compared to...) Figure 2 The difference between the profile pressing parts shown is that the second distance F' of the third protruding end face 223a of the lower pressing part 220 relative to the bottom 285 of the lower pressing part is lower than the first distance F of the fourth protruding end face 224a relative to the bottom 285 of the lower pressing part. Furthermore, the dimensions of the second joint 212 and the fourth joint 222 are also different. In particular, the vertical distance L1 between the suspended outer end point of the second groove 250 of the second joint 212 and the end face of the fourth protrusion 224 of the fourth joint 222 is less than or equal to the width H of the side groove 120. The suspended outer end point A' is the lowest point where the second groove 250 contacts the third protrusion 132 of the profile 100a when the profile pressing part 200c is joined to the profile 100a, and the suspended outer end point A' is higher than the outer end point A. The height difference e1 between the suspended outer end point A' and the outer end point A is equal to the height f of the third protrusion 132. Furthermore, the vertical distance F between the bottom surface of the fourth protrusion 224 and the bottom surface 285 of the lower pressing member is greater than or equal to the vertical distance (f+t) between the bottom surface 141 of the second opening and the bottom surface 150 of the profile. These designs facilitate easier insertion of the profile pressing member 200c into the side groove 120 of the profile 100a, while maintaining its fixed position after assembly. Other structural features of the profile pressing member in this embodiment are similar to... Figure 2 and Figure 9 The illustrated embodiments are similar and can be used as a reference.

[0153] In this embodiment, the design of the relationship between L1 and H ensures that after the profile pressing member 200c is installed in place by the fastener 231, the other profile 100a can still be attached to the profile pressing member 200c. In some embodiments, a chamfer can be designed at the position where the lower left corner of the profile 100a contacts the bracket 400 to reduce the passively excessive height of the profile 100a during installation, thereby reducing the height of the suspended outer end point A'. If the fastener 231 is not tightened during installation, then, as in other embodiments, the profile pressing member 200c has a vertical movement of the height f of the third protrusion 132, and the second joint 212 and the fourth joint 222 only need to satisfy the relationship between L and H.

[0154] When profile 100a mates with profile pressing member 200c, the third protrusion 223 passes over the fourth protrusion 142 of one profile 100a and engages in its second opening 140, after which the fourth protrusion 142 engages in the third groove 260 and abuts against the top surface of the third groove 260. The fourth protrusion 224 passes over the fourth protrusion 142 of another profile 100a and engages in its second opening 140, after which the fourth protrusion 142 enters the fourth groove 270, with the fourth protrusion 142 facing the fourth protrusion 224. Further, the profile pressing member 200c is fixed to the bracket 400 by fasteners 231, and two profiles 100a installed on the left and right sides of the profile pressing member 200c are also fixed simultaneously. In this embodiment, the fasteners 231 include screws 231a and nuts 231b. Figure 29 This is an installation cross-sectional view of the profile 100a and profile clamping member 200c used in this embodiment. Figure 30 This is a side view of the profile during installation. The installation and mating method between profile 100a and profile clamping member 200c is as follows: Figures 29-30 As shown, the installation process of profile 100a and profile pressing component 200c will not be described in detail here.

[0155] In this embodiment, the fifth protrusion 215 and the sixth protrusion 216 of the upper pressure member 210 have different heights, which is intended to make it easier for installers to distinguish the first joint 211 and the second joint 212. In one embodiment of this application, the upper pressure member 210 can be axially symmetrical, and the heights of the fifth protrusion 215 and the sixth protrusion 216 are the same.

[0156] In another embodiment of this application, an elastic strip (not shown) may be provided at the top of the fourth groove 270. When the fourth protrusion 224 passes over the fourth protrusion 142 of the profile 100a, the fourth protrusion 142 is engaged in the fourth groove 270 and fits against the elastic strip, making the connection between the profile 100a and the profile pressing member 200c more stable. The elastic strip may be a rubber strip or a spring clip.

[0157] like Figures 31-33As shown, when it is necessary to disassemble the mating connection between profile 100a and profile clamp 200c to maintain photovoltaic module 300, fastener 231 can be removed first. For example, by tightening nut 231b, nut 231b and screw 231a can be removed. Then, an external force, such as a pushing or pulling force, is applied to the upper clamp 210 or lower clamp 220 to cause relative sliding and separation between the upper clamp 210 and lower clamp 220. After the upper clamp 210 and lower clamp 220 are separated, they can no longer fix profile 100a, and the upper clamp 210 cannot engage with the third protrusion 132 of profile 100a, and the lower clamp 220 cannot engage with the fourth protrusion 142 of profile 100a. Therefore, the third protrusion 132 and the fourth protrusion 142 of profile 100a do not prevent the upper clamp 210 and lower clamp 220 from exiting the side groove 120 of profile 100a. The upper pressure member 210 is placed at the midpoint of the two profiles 100a along the second direction z, and then removed along the first direction x. The lower pressure member 220 is placed at the midpoint of the two profiles 100a along the second direction z, and then removed along the first direction x. This operation is repeated until the profile pressure members 200c connected to the left profile 100a and the right profile 100a are separated. After this separation, the left photovoltaic module 300 and the right photovoltaic module 300 can be maintained or replaced.

[0158] like Figure 31 and Figures 34-35 As shown, another method for separating the upper pressure member 210 and the lower pressure member 220 is illustrated. First, fastener 231 (not shown) is removed. Then, an external force is applied to cause the upper pressure member 210 and the lower pressure member 220 to slide relative to each other and separate. After the upper pressure member 210 and the lower pressure member 220 separate, the upper pressure member 210 is deflected by a certain angle and then pulled away along the first direction x. The lower pressure member 220 is deflected by a certain angle and then pulled away along the first direction x.

[0159] This application divides the profile pressing member 200c into an upper pressing member 210 and a lower pressing member 220, which are engaged by a combination of a slot and a protrusion to fix the profile 100a and the photovoltaic module 300. When separation is required, the profile 100a and the profile pressing member 200c can be disassembled by separating the upper pressing member 210 and the lower pressing member 220. After multiple rows or columns of photovoltaic modules 300 are installed, the photovoltaic module 300 located in the middle that requires maintenance can be easily and quickly removed, reducing the difficulty of maintaining the photovoltaic module 300 and improving the maintenance efficiency.

[0160] Similarly, it should be noted that, in order to simplify the description of this application and thus aid in the understanding of one or more embodiments of this application, the foregoing description of the embodiments of this application sometimes combines multiple features into a single embodiment, drawing, or description thereof. However, this disclosure method does not imply that the subject matter of this application requires more features than those mentioned in the claims. In fact, the embodiments have fewer features than all the features of the single embodiment disclosed above.

[0161] In some embodiments, numbers describing the quantity of components and attributes are used. It should be understood that such numbers used in the description of embodiments are modified in some examples with the terms "approximately," "approximately," or "generally."

Accordingly, in some embodiments, the numerical parameters used in the specification and claims are approximate values, which may be changed according to the characteristics required by individual embodiments. In some embodiments, numerical parameters should take into account specified significant digits and employ a general method of digit reservation.
