Description

Technical Field

[0001] The present application mainly relates to installation components of photovoltaic modules, and in particular to a profile installation component, a photovoltaic system and an installation method thereof. Background Art

[0002] The invention patent with publication number CN115589189A, entitled "Profile Pressing Piece, Profile, Photovoltaic Module Frame, Photovoltaic System and Assembly Method Thereof", discloses a profile and a profile pressing piece. The profile has a side groove, and the upper end of the groove of the side groove has a first ridge and the lower end has a second ridge. The profile pressing piece is integrally formed and has a first protrusion and a second protrusion. The first protrusion can pass over the first ridge and snap into the top of the side groove, and the second protrusion can pass over the second ridge and snap into the bottom of the side groove, so as to achieve the installation of the photovoltaic module. When using this type of profile pressing piece, the profile pressing piece needs to be rotated a certain angle so that the ridge is aligned with the side groove of the profile and snaps into the side groove to achieve the fixation of the profile. When installing another profile, since the profile pressing piece is fixedly installed, the side groove of the profile needs to be rotated a certain angle to combine with the profile pressing piece. The profile generally clamps the photovoltaic module, so it is necessary to drive the photovoltaic module and the profile to rotate together, and the installation method is relatively cumbersome. Moreover, when installing photovoltaic modules at higher locations (such as rooftops), this installation method is very difficult to implement, the safety of installation workers is difficult to guarantee during the installation process, and the applicable scenarios are relatively narrow.

[0095] To more clearly illustrate the technical solutions of the embodiments of this application, the following is a brief introduction to the drawings required for describing the embodiments. Obviously, the drawings described below are merely examples or embodiments of this application. Those skilled in the art can apply this application to other similar scenarios based on these drawings without inventive effort. Unless otherwise apparent from the context or otherwise noted, the same reference numerals in the figures represent the same structure or operation.

[0096] As used herein, unless the context clearly indicates otherwise, the terms "a," "an," "an," and / or "the" are not intended to refer to the singular but may include the plural. Generally speaking, the terms "include" and "comprise" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.

[0097] Unless otherwise specified, the relative arrangement of the parts and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present application. Meanwhile, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to actual proportional relationships. Technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments can have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, and therefore, once an item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0098] In the description of this application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of this application; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0099] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0100] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is solely 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. Furthermore, while the terms used in this application are selected from commonly known and commonly used terms, some terms mentioned in this specification may have been selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant sections of this description. Furthermore, this application should be understood not only by the actual terms used, but also by the meaning implied by each term.

[0101] Flowcharts are used in this application to illustrate the operations performed by systems according to embodiments of the present application. It should be understood that the preceding or following operations are not necessarily performed in exact order. Instead, the various steps may be processed in reverse order or simultaneously. Furthermore, other operations may be added to these processes, or one or more operations may be removed from these processes.

[0102] Figure 1 It is a schematic diagram of the three-dimensional structure of the profile to be combined and fixed by the profile installation assembly of an embodiment of the present application. The profile 200 includes an outer frame 203 and a bearing portion 204. A cavity 205 is provided in the outer frame 203. The side of the outer frame 203 has a side groove 206 for combining the profile 200 installation assembly. The bearing portion 204 is located above the outer frame 203 and is used to carry the workpiece to be installed. In some embodiments of the present application, the workpiece to be installed is a photovoltaic module. The upper end of the side groove 206 of the profile 200 has a first ridge 201, and the lower end of the side groove 206 has a second ridge 202. In some embodiments of the present application, the profile 200 can also be of other structural types. For details, please refer to the patent document with publication number CN115589189A ("Profile pressing part, profile, photovoltaic module frame, photovoltaic system and assembly method thereof"), which will not be repeated here.

Figure 7 for Figure 4 Top view of . Figure 8 This is a schematic diagram of the cooperation between the retaining member 170 and the engaging member 160 provided in one embodiment of the present application. Figures 1-8 Explain in detail the structure of the profile mounting assembly.

[0104] like Figure 1-Figure 3 As shown, the present application provides a profile mounting assembly for combining and fixing a profile 200. A side groove 206 is provided on one side of the profile 200. The profile mounting assembly includes a main pressing member 110, a locking member 160 and a retaining member 170. Figure 4 As shown, the first side 111 of the main pressing member 110 is provided with a first side plate 140, and the first side plate 140 is used to fix the side groove 206 of a profile 200; the engaging member 160 is provided on the second side 112 of the main pressing member 110, and the second side 112 of the main pressing member 110 is arranged opposite to the first side 111 of the main pressing member 110. Among them, the retaining member 170 is detachably connected to the engaging member 160 and is configured such that: when the retaining member 170 is engaged with the engaging member 160, the retaining member 170 holds the engaging member 160 in the initial position; when the retaining member 170 is separated from the engaging member 160, the engaging member 160 moves to a fixed position to fix the side groove 206 of another profile 200. The state diagram of the retaining member and the engaging member 160 when engaged can be referred to. Figure 8 The state diagram of the retaining member and the engaging member 160 when separated can be referred to Figure 10 .

[0105] In this application, the first side plate 140 of the main pressure member 110 can secure the side groove 206 of the profile 200. When installing another profile 200, the retaining member 170 can be separated from the engaging member 160, and the engaging member 160 will move to a fixed position and engage with the side groove 206 of the other profile 200 to secure the other profile 200. This profile mounting assembly can reduce the number of installation steps and ease the installation difficulty during the profile 200 installation process; increase the speed and cost of photovoltaic module installation; improve the structural reliability of the profile mounting assembly; and expand its application scenarios.

[0106] like Figure 1-Figure 4 and Figure 6 As shown, in some embodiments, the first side plate 140 is provided with a first protrusion 141 and a second protrusion 142 along the first direction x, the first protrusion 141 is above the first side plate 140, and the second protrusion 142 is below the first side plate 140, and the three are integrally formed. Figure 1 、 Figure 2 and Figure 4As shown, it can be imagined that when the main pressure member 110 is coupled to the profile 200, the first protrusion 141 snaps into the top surface 207 of the side groove 206, and the second protrusion 142 snaps into the bottom surface 208 of the side groove 206, thereby securing the profile 200. The provision of the first protrusion 141 and the second protrusion 142 allows one side of the profile mounting assembly to be tightly connected to the profile, improving the stability of the profile mounting assembly. In some embodiments, the first protrusion 141 and the profile 200 have a special design, allowing the main pressure member 110 to tilt at a small angle relative to the bottom surface 209 of the profile 200, allowing it to be inserted from the side into the side groove 206 of the profile 200. The special design and angle design of the main pressure member 110 and the profile 200 can be referenced in patent document CN115589189A ("Profile Pressure Member, Profile, Photovoltaic Module Frame, Photovoltaic System, and Assembly Method Thereof"), and will not be elaborated here.

[0107] like Figure 4 As shown, in some embodiments, the main pressure member 110 is further provided with a first pressure plate 120 and a second pressure plate 130, and the first pressure plate 120 and the second pressure plate 130 are arranged opposite to each other; the first side 121 of the first pressure plate 120 is connected to the first side plate 140, and the second side 122 of the first pressure plate 120 is provided with a first guide member 123; the first side 131 of the second pressure plate 130 is connected to the first side plate 140, and the second side 132 of the second pressure plate 130 is provided with a second guide member 133; the engaging member 160 is provided with a guide rail, and the guide rail can be cooperated and connected with the first guide member 123 and / or the second guide member 133 so that the engaging member 160 can move along the second direction y.

[0108] refer to Figure 4 and Figure 7 As shown, in some embodiments, the main pressing member 110 is further provided with a second side plate 150. The second side plate 150 is disposed opposite the first side plate 140 and connected to the first pressing plate 120 and the second pressing plate 130. The second side plate 150 is provided with an opening 151. The retaining member 170 is disposed through the opening 151 and is configured to be movable along the second direction y through the opening 151. In some embodiments, the retaining member 170 is moved along the second direction y into the main pressing member 110 under the thrust of the profile 200. For example, the retaining member 170 moves from the second side plate 150 toward the first side plate 140, and the retaining member 170 moves into the main pressing member 110 and connects with the first side plate 140.

[0109] like Figures 1-6As shown, in some embodiments, a third protrusion 134 is further provided at the bottom of the second pressure plate 130. The third protrusion 134 cooperates with the second protrusion 142 to support the main pressure member 110, making the main pressure member 110 more stable and preventing it from tilting. In the second direction y, the third protrusion 134 is closer to the first side plate 140 than the second side plate 150. When the engaging member 160 is engaged with the side groove 206, the second protrusion 202 can contact the third protrusion 134. The length of the third protrusion 134 along the first direction x is equal to the sum of the length of the second protrusion 142 and the bottom thickness of the profile 200. The bottom thickness of the profile 200 refers to the thickness between the bottom surface 209 of the profile 200 and the bottom surface 208 of the side groove 206. When this length requirement is met, the main pressure member 110 will not tilt when installed on a plane, and will be more stable during installation and use.

[0110] like Figure 2-Figure 5 As shown, in some embodiments, the profile mounting assembly further includes a fastener 180. The first pressing plate 120 and the second pressing plate 130 are respectively provided with fastening holes 124. The fastening holes 124 are arranged opposite to each other. The fastener 180 passes through the fastening holes 124 and is fixedly connected to the bracket 300 of the profile 200. The fastener 180 can be a bolt and a nut. The fastening hole 124 is provided at the center of the first pressing plate 120 and the second pressing plate 130. The bolt passes through the fastening hole 124 to fix the main pressing member 110 to the bracket 300.

[0111] like Figure 8 and Figure 9 As shown, in some embodiments, the engaging member 160 includes a limiting portion 161, and the retaining member 170 includes a blocking portion 171 and an escape opening 172. When the retaining member 170 is engaged with the engaging member 160, the blocking portion 171 abuts the limiting portion 161; when the limiting portion 161 is located in the escape opening 172, the retaining member 170 separates from the engaging member 160. The blocking portion 171 and the limiting portion 161 are disposed opposite each other and can abut each other. When abutting, the blocking portion 171 can prevent the engaging member 160 from moving in a first direction x. Furthermore, the retaining member 170 can move relative to the engaging member 160 in a second direction y. When the limiting portion 161 is located in the escape opening 172, the blocking portion 171 cannot abut the limiting portion 161, so the engaging member 160 and the retaining member 170 separate. The cooperation between the retaining member 170 and the engaging member 160 allows for quick installation of the profile 200 without rotating the profile's side grooves to a certain angle. For example, when a profile 200 is pushed toward the second side 112 of the main pressure member 110, the retaining member 170 moves inward. When the stopper 161 is located at the avoidance opening 172, the engaging member 160 engages with the profile 200.

[0112] Combine Figure 8 and Figure 9In some embodiments, the limiting portion 161 includes a first folding edge 161a, and the blocking portion 171 includes a second folding edge 171a. The first folding edge 161a can be as follows. Figure 8 As shown, there is only one bend. In some embodiments, the first fold 161a may have multiple bends. The second fold 161b may have only one bend or multiple bends. As long as the first fold 161a can abut against the second fold 161b. After abutment, the engaging member 160 and the retaining member 170 will not separate in the second direction y. When the retaining member 170 is matched with the engaging member 160, the first fold 161a abuts against the second fold 171a. The first side 162 of the engaging member 160 is provided with a first fold 161a; the bottom of the retaining member 170 is provided with a second fold 171a, and the retaining member 170 is provided on the first side 162 of the engaging member 160. In some embodiments, the first fold 161a and the second fold 171a are arranged relative to each other. The folding directions of the first folding edge 161a and the second folding edge 171a are opposite to each other, so that the first folding edge 161a and the second folding edge 171a are in contact with each other; and the first folding edge 161a and the second folding edge 171a are not easily separated. In some embodiments, the first folding edge 161a is arranged along the length direction of the engaging member 160 (i.e., the second direction y); the second folding edge 171a is arranged along the length direction of the retaining member 170 (i.e., the second direction y). That is to say, the first folding edge 161a and the second folding edge 171a have a certain length along the second direction y. Figure 9 As shown, in some embodiments, the engaging member 160 has a symmetrical structure, and a first folded edge 161a is also provided on the second side 163 of the engaging member 160. Accordingly, two retaining members 170 are provided to more stably maintain the initial position of the engaging member 160. For example, one retaining member 170 is provided on the first side 162 of the engaging member 160, and the other retaining member 170 is provided on the second side 163 of the engaging member 160. When the second folded edges 171a of the two retaining members 170 respectively abut against the first folded edges 161a, the engaging member 160 is maintained in the initial position.

[0113] In some embodiments, the retaining member 170 is fixed in the first direction x and can move in the second direction y; the second folded edge 171a is close to the bottom of the retaining member 170. Since the retaining member 170 is fixed in the first direction x, when the second folded edge 171a abuts against the first folded edge 161a, the retaining member 170 and the engaging member 160 will not move in the first direction x. The engaging member 160 and the retaining member 170 can be rectangular flat plates, and the retaining member 170 clamps the engaging member 160 in the initial position by the abutment of the second folded edge 171a and the first folded edge 161a. Figure 1 and Figure 3As shown, in some embodiments, the initial position means that the height h3 of the bottom of the engaging member 160 relative to the bottom surface 209 of the profile 200 is greater than the height h1 of the second protrusion 202 relative to the bottom surface 209 of the profile 200. When this condition is met, the profile 200 can be directly placed on the second side 112 of the main pressing member 110.

[0114] Continue to refer Figure 8 As shown, in some embodiments, the engaging member 160 includes a first engaging member 160a, a second engaging member 160b, and an elastic member 166. The first engaging member 160a and the second engaging member 160b are connected by the elastic member 166. When the engaging members (the first engaging member 160a and the second engaging member 160b) are maintained in the initial position, the elastic member 166 is in a first state. When the engaging members (the first engaging member 160a and the second engaging member 160b) are moved to the fixed position, the elastic member 166 is in a second state. In some embodiments, there are multiple elastic members 166, and the elastic members 166 can be springs.

[0115] It should be noted that in some embodiments, the engaging member 160 is a structural member. Figure 8 As shown, the engaging member may include only the second engaging member 160b. The second engaging member 160b has a first folded edge 161a on its first side and a first folded edge 161a on its second side. The second engaging member 160b has a second guide rail 165 that is matingly connected to the second guide member 133. A retaining member 170 is disposed on both sides of the second engaging member 160b, with the second folded edges 171a abutting against the first folded edges 161a, respectively. When the second engaging member 160b abuts the retaining member 170, the second engaging member 160b is in an initial position. When the first folded edge 161a is located at the avoidance opening 172a, the second engaging member 160b separates from the retaining member 170. The second engaging member 160b has a certain gravity. Under the action of gravity, the second engaging member 160b moves downward in the first direction x under the action of the second guide member 133, engaging the bottom surface 208 of the side groove.

[0116] Continue to refer Figure 8 As shown, in some embodiments, when the first engaging member 160a and the second engaging member 160b are in the initial position, the spring is in the first state. In these embodiments, the first state means that the spring is in a compressed state, and the elastic force generated by the spring can cause the first engaging member 160a to have a tendency to move upward along the first direction x, and the second engaging member 160b to have a tendency to move downward along the first direction x. However, due to the retaining effect of the retaining member, the first engaging member 160a and the second engaging member 160b cannot move in the second direction and are retained in the initial position. Figure 10As shown, when the first engaging member 160a and the second engaging member 160b are moved to the fixed position, the elastic member 166 is in the second state. Here, the second state can refer to the spring being in a relaxed state, with no elastic force. In some embodiments, the second state can also refer to the spring being in a compressed state, but the degree of compression is less than that in the first state, resulting in a lower elastic force. The spring in the second state can overcome the weight of the first engaging member 160a, maintaining the first engaging member 160a in the fixed position, and the first engaging member 160a will remain engaged with the top surface 207 of the side groove.

[0117] refer to Figures 8-10 As shown, in some embodiments, the first engaging member 160a is provided with a third folded edge 161b, and the third folded edge 161b is disposed on a first side of the first engaging member 160a. The first engaging member 160a can have a symmetrical structure, and the third folded edge 161b can also be disposed on a second side of the first engaging member 160a. The second engaging member 160b is provided with a first folded edge 161a, and the first folded edge 161a is disposed on a first side of the second engaging member 160b. The second engaging member 160b can have a symmetrical structure, and the first folded edge 161a can also be disposed on a second side of the second engaging member 160b. The third folded edge 161b on the first engaging member 160a is disposed opposite the first folded edge 161a of the second engaging member 160b. The first folded edge 161a can be disposed along the width direction (second direction y) of the second engaging member 160b, and the third folded edge 161b can be disposed along the width direction (second direction y) of the first engaging member 160a. Correspondingly, the retaining member is further provided with a fourth folding edge 171b, which is arranged at the top of the retaining member and is arranged opposite to the second folding edge 171a. The fourth folding edge 171b is folded in the opposite direction to the third folding edge 161b so that the fourth folding edge 171b and the third folding edge 161b abut against each other. The second folding edge 171a and the fourth folding edge 171b of the retaining member can be arranged along the length direction of the retaining member (second direction y). The retaining member can be provided with two, one of which is arranged on one side of the first engaging member 160a and the second engaging member 160b, and the other retaining member is arranged on the other side of the first engaging member 160a and the second engaging member 160b. Providing two retaining members can more stably maintain the initial position of the engaging member. When the retaining member cooperates with the first engaging member 160a and the second engaging member 160b, the first folded edge 161a abuts against the second folded edge 171a, and the third folded edge 161b abuts against the fourth folded edge 171b, and the first engaging member 160a and the second engaging member 160b remain in the initial position.

[0118] In these embodiments, Figure 1 and Figure 3As shown, the first engaging member 160a remains in the initial position, meaning that a height h4 of the first engaging member 160a relative to the bottom surface 209 of the profile 200 is lower than a height h2 of the first protrusion 201 relative to the bottom surface 209 of the profile 200. The second engaging member 160b remains in the initial position, meaning that a height h3 of the second engaging member 160b relative to the bottom surface 209 of the profile 200 is higher than a height h1 of the second protrusion 202 relative to the bottom surface 209 of the profile 200. When the first engaging member 160a and the second engaging member 160b are in the initial position, the profile 200 can be positioned on the second side 112 of the main pressure member 110 and connected to the first and second pressure plates 120 and 130.

[0119] like Figure 8 As shown, in some embodiments, the second folded edge 171a is provided with a first avoidance opening 172a, and the fourth folded edge 171b is provided with a second avoidance opening 172b. The first avoidance opening 172a is provided at the end of the second folded edge 171a, and the second avoidance opening 172b is provided at the end of the fourth folded edge 171b. The end of the second folded edge 171a is close to the second side panel 150, and the end of the fourth folded edge 171b is close to the second side panel 150. The length of the first avoidance opening 172a can be slightly greater than the length of the first folded edge 161a, and the length of the second avoidance opening 172b can be slightly greater than the length of the third folded edge 161b, so as to facilitate separation of the retaining member 170 from the first engaging member 160a, and to facilitate separation of the retaining member 170 from the second engaging member 160b. When the retaining member 170 moves to a certain position along the second direction y under the thrust of the profile 200, the first folded edge 161a and the third folded edge 161b will be located in the first avoidance opening 172a and the second avoidance opening 172b. At this time, the retaining member 170 will be separated from the first engaging member 160a and the retaining member will be separated from the second engaging member 160b.

[0120] Figure 9 Schematic diagram of a process 1 of separating the first engaging member 160a and the second engaging member 160b according to an embodiment of the present application. Figure 10 Schematic diagram of process 2 of separating the first engaging member 160a and the second engaging member 160b provided in one embodiment of the present application.

[0121] Combine Figure 8 and Figure 9 From the content shown, it can be found that the retaining member 170 has been displaced along the second direction y, but at this time the first fold 161a and the second fold 171a are still in contact, the third fold 161b and the fourth fold 171b are also in contact, and the spring is in the first state. Figures 8-10As shown, retaining member 170 undergoes significant displacement along the second direction y. First folded edge 161a is positioned within first escape opening 172a, while third folded edge 161b is positioned within second escape opening 172b. Retaining member 170 is separated from first engaging member 160a and second engaging member 160b. Under the elastic force of the spring, first engaging member 160a moves upward, while second engaging member 160b moves downward. When first engaging member 160a and second engaging member 160b are respectively moved to their fixed positions, the spring enters the second state.

[0122] refer to Figure 2-Figure 7 As shown, in some embodiments, the first engaging member 160a is provided with a first guide rail 164, which is cooperatively connected to the first guide member 123. The second engaging member 160b is provided with a second guide rail 165, which is cooperatively connected to the second guide member 133. When the retaining member 170 moves to a certain position along the second direction y under the thrust of the profile 200, the first folded edge 161a will be located in the first avoidance opening 172a, and the third folded edge will be located in the second avoidance opening 172b. At this time, the retaining member 170 will separate from the first engaging member 160a, and the retaining member 170 will also separate from the second engaging member 160b. Accordingly, under the action of the spring force and the guidance of the first guide member 123, the first engaging member 160a will move upward along the first direction x and engage the top surface 207 of the side groove 206 of the profile 200. Under the action of the spring force and the guidance of the second guide member 133, the second engaging member 160b moves downward in the first direction x, engaging with the bottom surface 208 of the side groove 206 of the profile 200. The fixed position means that the first engaging member 160a moves to the top surface 207 of the side groove 206, and the second engaging member 160b moves to the bottom surface 208 of the side groove 206. During the movement of the first and second engaging members 160a, 160b to the fixed position, the first guide member 123 and the first guide rail 164 do not separate, and the second guide member 133 and the second guide rail 165 do not separate.

[0123] like Figure 4 and Figure 8As shown, in some embodiments, the widths of the first guide member 123 and the second guide member 133 gradually increase along the second direction y; the widths of the first guide rail 164 and the second guide rail 165 also gradually increase along the second direction y. For example, the first guide member 123 and the second guide member 133 may be dovetail groove blocks, whose cross-sections are similar to a trapezoid and whose widths gradually increase along the second direction y. Accordingly, the first guide rail 164 and the second guide rail 165 are dovetail grooves that can be mated with the dovetail groove blocks. In the first direction x, the first guide rail 164 can slide freely, and the second guide rail 165 can also slide freely. It can be imagined that the design of gradually increasing widths along the second direction y allows the first guide member 123 and the first guide rail 164 to be tightly engaged together, preventing them from separating in the second direction y. The same applies to the second guide member 133 and the second guide rail 165. Therefore, after the first engaging member 160a and the second engaging member 160b move to the fixed position, the first engaging member 160a and the second engaging member 160b can fix the side groove 206 of the profile 200, so that the profile 200 cannot move in the second direction y.

[0124] like Figure 4 、 Figure 5 and Figure 7 As shown, in some embodiments, the second side 122 of the first pressure plate 120 is provided with a first groove 125, and the second side 132 of the second pressure plate 130 is provided with a second groove 135. The first guide member 123 is provided in the first groove 125, and the second guide member 133 is provided in the second groove 135. The first engaging member 160a is provided in the first groove 125 and is connected to the first guide member 123, and the second engaging member 160b is provided in the second groove 135 and is connected to the second guide member 133. The second side plate 150 is provided on the second side 112 of the main pressure member 110 and is provided on the inner sides of the first groove 125 and the second groove 135, and is used to connect the first pressure plate 120 and the second pressure plate 130. Figure 13 Because the second side plate 150 is disposed inside the first groove 125 and the second groove 135, when the profile 200 approaches the second side 112 of the main pressure member 110, the first protrusion 201 can abut the upper surface of the first pressure plate 120, and the second protrusion 202 can abut the lower surface of the second pressure plate 130, so that the first and second pressure plates 120 and 130 can contact the inner side of the outer frame 203 of the profile 200. Because the first protrusion 201 abuts the upper surface of the first pressure plate 120 and the second protrusion 202 abuts the lower surface of the second pressure plate 130, after the main pressure member 110 is fixed, the profile 200 cannot move in the first direction x, and the profile 200 can be effectively fixed.

[0125] like Figure 4-Figure 6 and Figure 8As shown, in some embodiments, the retaining member 170 is further provided with a first extension portion 173 and a second extension portion 174, and the first extension portion 173 and the second extension portion 174 respectively have a latching tooth 175; the first side plate 140 is further provided with a first supporting plate 143 and a second supporting plate 144, the first extension portion 173 is provided on the first supporting plate 143, and the second extension portion 174 is provided on the second supporting plate 144; the first supporting plate 143 and the second supporting plate 144 are provided with a limiting tooth 145, and the latching tooth 175 is engaged with the limiting tooth 145. The first supporting plate 143 abuts the first extension 173, and the second supporting plate 144 abuts the second extension 174. The engaging engagement of the latching teeth 175 with the limiting teeth 145 provides support for the retaining member 170, preventing it from moving in the first direction x. It also secures the retaining member 170, preventing it from sliding out of the opening 151 of the second side plate 150 due to external forces. In some embodiments, the first supporting plate 143 and the second supporting plate 144 are disposed on the inner side of the first side plate 140; each of the first extension 173 and the second extension 174 is provided with a plurality of limiting teeth 145.

[0126] Continue to refer Figure 4-Figure 6 and Figure 13 As shown, in some embodiments, a first extension 173 is disposed at the top of the retaining member 170, and a second extension 174 is disposed at the bottom of the retaining member 170. The first extension 173, the second extension 174, and the retaining member 170 are integrally formed. The first extension 173 is provided with a plurality of latching teeth 175. The latching teeth 175 of the first extension 173 are tilted in the opposite direction to the retaining teeth 145 on the first supporting plate 143, thereby forming a snap-fitting fit. The second extension 174 is provided with a plurality of latching teeth 175. The latching teeth 175 of the second extension 174 are tilted in the opposite direction to the retaining teeth 145 on the second supporting plate 144, thereby forming a snap-fitting fit.

[0127] In some embodiments, the first extension portion 173 and the second extension portion 174 may be provided with two latching teeth 175, respectively. Figure 13 As shown, in the initial state, the first latch tooth 175a is engaged with the limiting tooth 145 on the support plate; when the retaining member 170 moves along the second direction y, the second latch tooth 175b approaches the limiting tooth 145, and when the first fold edge 161a and the third fold edge 161b are located at the first avoidance opening 172a and the second avoidance opening 172b, the second latch tooth 175b is engaged with the limiting tooth 145.

[0128] In some embodiments, a plurality of limiting teeth 145 may be provided. Figure 6It can be imagined that, for example, for a supporting plate, the number of the limiting teeth 145 is two, which are recorded as the first limiting tooth and the second limiting tooth. The second limiting tooth is closer to the first side plate 140 than the first limiting tooth. When the second latch 175b is engaged with the first limiting tooth, the first latch 175a is engaged with the second limiting tooth. Through the cooperation between the first extension 173 and the first supporting plate 143, the cooperation between the second extension 174 and the second supporting plate 144, and the engagement between the limiting tooth 145 and the latch 175, the retaining member 170 can be stably passed through the opening 151 of the second side plate 150 and reliably maintain the first engaging member 160a and the second engaging member 160b in the initial position. In some embodiments, the length of the first extension 173 and the second extension 174 is less than the distance between the first side plate 140 and the second side plate 150. By designing the size relationship between the length and the length of the avoidance opening, the retaining member 170 can have a larger movement space, so that the first folded edge 161a and the third folded edge 161b can fall into the first avoidance opening 172a and the second avoidance opening 172b.

[0129] refer to Figure 2-Figure 4 and Figure 11-13 The present application also provides a photovoltaic system, comprising a profile 200, a bracket 300, and the profile mounting assembly as described above. The profile 200 has a bearing portion 204 for supporting a workpiece to be mounted. A side groove 206 is provided on one side of the profile 200. One of the two adjacent profiles 200 is mounted on the first side 111 of the main pressure member 110 through the side groove 206, and the other is mounted on the second side 112 of the main pressure member 110 through the side groove 206. The profile mounting assembly is fixedly connected to the bracket 300. In some embodiments, the workpiece to be mounted is a photovoltaic module to achieve the installation of the photovoltaic module. The bracket 300 can be a bracket 300 of various shapes to adapt to different practical scenarios, such as a bracket 300 with a "U"-shaped cross-section. The main pressure member 110 is connected to the bracket 300 by bolts. Since the connecting member and the retaining member 170 are both provided on the main pressure member 110, fixing the main pressure member 110 is equivalent to fixing the connecting member and the retaining member 170.

[0130] like Figure 14 As shown, the present application also provides a method for installing a photovoltaic system, comprising the following steps:

[0131] S300, installing the first side plate 140 of the profile installation assembly described above into the side groove 206 of a profile 200;

[0132] S301, use fasteners 180 to fix the profile mounting assembly on the bracket 300;

[0133] S302. Place the side groove 206 of another profile 200 on the second side of the profile mounting assembly, push the profile 200 along the second direction y and drive the retaining member 170 to move along the second direction y. After the retaining member 170 is separated from the engaging member 160, the engaging member 160 moves to a fixed position and engages with the side groove 206 of the profile 200.

[0134] Figure 11 A schematic diagram of process 1 of the installation method provided in one embodiment of the present application. Figure 12 A schematic diagram of process 2 of the installation method provided in one embodiment of the present application. Figure 13 This is a schematic diagram of process 3 of the installation method provided in one embodiment of the present application. Figure 11 As shown, first install the profile mounting assembly in the side groove 206, and connect the profile mounting assembly to the bracket 300 through the fastener 180. At this time, the retaining member 170 keeps the first engaging member 160a and the second engaging member 160b in the initial position, and the locking teeth 175 are engaged with the limiting teeth 145. Figure 12 As shown, another profile 200 is close to the second side 112 of the main pressing member 110, the first ridge 201 is located on the upper surface of the first pressing plate 120, and the second ridge 202 is located on the lower surface of the second pressing plate 130. The retaining member 170 contacts the profile 200 and moves inward under the thrust of the profile 200. Figure 8 and Figure 13 It can be imagined that when the retaining member 170 moves inward, the first folded edge 161a and the third folded edge 161b are respectively in the first avoidance opening 172a and the second avoidance opening 172b, the first engaging member 160a is snapped into the top surface 207 of the side groove 206, the second engaging member 160b is snapped into the bottom surface 208 of the side groove 206, and the second engaging tooth 175b is snapped into engagement with the limiting tooth 145. At this time, the profile 200 is stably fixed to the second side 112 of the main pressure member 110.
