[0002] This application claims priority to Chinese patent application number 2023117830704, filed on December 22, 2023, entitled “Profile mounting assembly, photovoltaic system and photovoltaic system installation method”, the entire text of which is hereby incorporated by reference. Technical Field

[0003] The present application relates to the technical field of photovoltaic assembly mounting accessories, and in particular to a profile mounting assembly, a photovoltaic system, and a photovoltaic system mounting method. Background Art

[0004] Solar photovoltaic modules are formed by securing laminated components, including solar cells, to a PV module frame. The module frame enhances the module's mechanical strength, seals the edges of the laminate, and secures the laminate to the mounting bracket, ultimately forming a solar photovoltaic module (abbreviated as a PV module or just a module). Therefore, the strength of the module frame determines the overall strength of the PV module.

[0005] In the related art, in order to improve the strength of the profile, a profile pressing block for combining and fixing the profile is provided to achieve the installation and fixation of the profile. Specifically, fixed structures that engage with the C-shaped side grooves in the two adjacent profiles are provided on opposite sides of the profile pressing block to achieve the fixation of the two adjacent profiles. During installation, the profile pressing piece is first tilted so that one side of the fixed structure on one side is engaged with one side of the C-shaped side groove of one profile, and then the profile pressing piece is rotated so that the other side of the fixed structure is also engaged with the C-shaped side groove. After the profile pressing piece is fixed to the bracket through the mounting piece, the other profile is tilted at a certain angle and a part of the C-shaped side groove is engaged with the fixed structure on the profile pressing piece, and then the profile is rotated so that the C-shaped side groove is completely engaged with the profile pressing piece, so that the profile and the bracket can be fixed.

[0006] However, for the above-mentioned profile pressing parts, when installing photovoltaic modules, the photovoltaic modules need to be tilted. Usually, photovoltaic modules weigh dozens of kilograms. When the installation position of the photovoltaic modules is at a certain height from the ground, tilting at a certain angle will make it inconvenient for operators to operate and increase the difficulty of installation.

[0067] The details of one or more embodiments of the disclosure are set forth in the accompanying drawings and the description below.

[0068] 1 to 13 , an embodiment of the present application provides a profile mounting assembly for combining and fixing a profile 310 , wherein a side groove 311 is constructed on one side of the profile 310 , and the profile mounting assembly includes a main pressure block 100 and an auxiliary pressure block 200 , wherein a first coupling portion 110 is provided on one side of the main pressure block 100 , and the first coupling portion 110 is used to combine with the side groove 311 of one profile 310 ; the auxiliary pressure block 200 is fixedly connected to a side of the main pressure block 100 opposite to the first coupling portion 110 , and a second coupling portion is provided on the auxiliary pressure block 200 , and the second coupling portion is used to combine with the side groove 311 of another profile 310 ; wherein the second coupling portion is configured to have a dimension in a first direction that gradually increases from a side away from the first coupling portion 110 to a side close to the first coupling portion 110 , and the first direction is a groove width direction along the side groove 311 when the first coupling portion 110 is combined with the side groove 311

[0069] This technical solution provides a profile mounting assembly. A first coupling portion 110 is provided on a main clamp 100. The first coupling portion 110 couples with the side groove 311 of a profile 310 in one photovoltaic module 300 to achieve connection between the profile 310 in one photovoltaic module 300 and the main clamp 100. A second coupling portion is provided on a secondary clamp 200. The second coupling portion couples with the side groove 311 of a profile 310 in another photovoltaic module 300 to achieve connection between the other photovoltaic module 300 and the secondary clamp 200. The secondary clamp 200 is fixedly connected to the main clamp 100 to achieve mutual connection between the two profiles 310. The profile mounting assembly is connected to a bracket to achieve connection between the profile 310 and the bracket. This arrangement facilitates the connection between the profile mounting assembly and the profile 310, thereby providing support for the profile 310 through the profile mounting assembly. The main pressure block 100 is used to provide strength and support for the photovoltaic module 300, while the secondary pressure block 200 is responsible for providing a pulling force. The second connecting portion is configured such that its dimension in the first direction gradually increases from the side away from the first connecting portion 110 to the side closer to the first connecting portion 110. This allows the profile 310 connected to the second connecting portion to be installed without tilting the photovoltaic module 300. Instead, the profile 310 can be connected to the secondary pressure block 200 by aligning the side groove 311 on the profile 310 in the photovoltaic module 300 with the second connecting portion and pushing it horizontally toward the main pressure block 100. This arrangement makes the installation between the photovoltaic module 300 and the profile mounting assembly more convenient and quick, while also reducing installation difficulty and saving effort.

[0070] It should be noted that, as can be understood with reference to FIG15 , the profile 310 is made of aluminum alloy and is formed as a single piece by extrusion. The profile 310 includes a frame and a support portion. The interior of the frame is hollow to form a cavity. A side groove 311 is provided on one side of the frame. A first flange 3111 and a second flange 3112 are connected to the sidewalls of the groove corresponding to the notch of the side groove 311. The first flange 3111 and the second flange 3112 are provided in the side groove 311 and extend in a direction close to each other, so that the side groove 311 is constructed as a C-shaped groove. The support portion is provided on the top side of the frame, and the support portion is used to support the workpiece to be installed. In the present application, the workpiece to be installed is a photovoltaic module.

[0071] It is understandable that the main pressure block 100 and the auxiliary pressure block 200 can be an integrally formed structure, or they can be two independent structures fixed together to form a profile mounting assembly. In this embodiment, the latter form is adopted, and a split structure is adopted, which is conducive to processing and forming, thereby reducing production costs; moreover, the main pressure block 100 and the auxiliary pressure block 200 can be made of different materials. For example, based on the consideration of processing performance and comprehensive cost, the main pressure block 100 can be set as an extruded aluminum alloy part; and in order to ensure the structural strength of the auxiliary pressure block 200, while taking into account factors such as processing performance and comprehensive cost, the auxiliary pressure block 200 can be an extruded aluminum alloy part, a steel sheet metal part, etc. As a preferred solution, as shown in Figures 4 and 5, the auxiliary pressure block 200 can be a sheet metal part formed by cold deformation of stainless steel or coated steel. Of course, in other embodiments, the surface of the spring steel can also be provided with an anti-corrosion coating.

[0072] In one embodiment, as shown in FIG15 , a first flange 3111 and a second flange 3112 are respectively provided on the two groove side walls corresponding to the groove opening of the side groove 311 of the profile 310. As shown in FIG5 to FIG8 , the auxiliary pressure block 200 includes an auxiliary pressure block body 220, and the second coupling portion includes a first connecting member and a second connecting member respectively connected to the two ends of the auxiliary pressure block body 220 along the first direction. The first connecting member is configured with a first protrusion at one end facing away from the auxiliary pressure block body 220; the second connecting member is configured with a second protrusion protruding away from the first connecting member at one end facing away from the auxiliary pressure block body 220; the first protrusion protrudes away from the second connecting member, and the first protrusion and the second protrusion respectively pass over the first flange 3111 and the second flange 3112 to be inserted into the side groove 311.

[0073] By arranging the first flange 3111 and the second flange 3112 on the two groove side walls corresponding to the groove opening of the side groove 311 of the profile 310, the first flange 3111 and the second flange 3112 are arranged relative to each other, so that when the second combining portion is combined with the side groove 311, the first flange 3111 and the second flange 3112 can block the second combining portion, thereby improving the reliability of the combination of the second combining portion and the side groove 311. The auxiliary pressure block body 220 is used to support the second combining part, by respectively arranging the first protrusion and the second protrusion on the first connecting member and the second connecting member connected to the auxiliary pressure block body 220, so that the first protrusion and the second protrusion protrude in the direction away from each other, so that when the first protrusion and the second protrusion respectively pass over the first flange 3111 and the second flange 3112 and are stuck in the side groove 311, the first protrusion and the second protrusion can resist each other with the first flange 3111 and the second flange 3112, thereby limiting the second combining part from escaping from the side groove 311 of the profile 310, so as to ensure the reliability of the connection between the profile 310 and the second combining part.

[0074] Specifically, the auxiliary pressure block 200 can be configured as follows: as shown in Figures 5 and 6, the auxiliary pressure block body 220 is a plate-like structure, and the opposite ends of the plate-like structure are bent and extended in the same direction. The bent portion and the plate body itself can be perpendicular to each other, or at an obtuse angle. The first protrusion and the second protrusion are respectively provided at one end of the two bent portions away from the body itself. Of course, the first protrusion and the second protrusion can be protrusions formed by setting the end of the bent portion to be relatively thicker; or they can be protrusions formed by bending the free end of the bent portion again. It can be understood that the first connecting member and the second connecting member are structures formed by a bent portion and a protruding portion. Through the above structural form, when the side groove 311 of the profile 310 is connected to the second joint part, in the process of the first protrusion and the second protrusion passing over the first flange 3111 and the second flange 3112, the two bent parts can elastically deform in the direction of approaching each other, so that the first protrusion and the second protrusion can more easily pass over the first flange 3111 and the second flange 3112, thereby allowing the operator to save more effort when installing the profile 310.

[0075] As shown in Figures 7 and 8, in one embodiment, the side surfaces of the first and second protrusions that are spaced apart from each other are both inclined, and the distance between the two side surfaces gradually increases from the side away from the auxiliary pressure block body 220 to the side closer to the auxiliary pressure block body 220. With this structure, the side surfaces of the first and second protrusions that are spaced apart from each other form guiding slopes, so that the guiding slopes can serve as guides when the first and second protrusions pass over the first and second flanges 3111 and 3112. This allows the second protrusion to engage with the side groove 311 of the profile 310 by simply pushing the profile 310 toward the auxiliary pressure block body 220, eliminating the need to tilt the profile 310 to a certain angle to engage the first protrusion into the side groove 311 and then rotate it to a certain angle before engaging the second protrusion into the side groove 311. This saves effort during installation, making installation of the profile 310 more convenient and quicker.

[0076] In one embodiment, the side surfaces of the first and second protrusions facing the auxiliary pressure block body 220 are respectively aligned with the first flange 3111 and the second flange 3112. The side surfaces of the first and second protrusions facing the auxiliary pressure block body 220 are aligned with the first flange 3111 and the second flange 3112 on the profile 310 to ensure more reliable mutual positioning between the first protrusion and the first flange 3111, and between the second protrusion and the second flange 3112.

[0077] As shown in Figures 7 and 8 , specifically, the side faces of the first and second protrusions that face away from each other form an acute angle with the side faces of the first and second protrusions that face toward the auxiliary pressure block body 220. Furthermore, the side faces of the first and second protrusions that face toward the auxiliary pressure block body 220 are parallel to the auxiliary pressure block body 220, and the first and second connecting members are respectively perpendicular to the auxiliary pressure block body 220.

[0078] As shown in Figures 3, 4 and 13, in one embodiment, the main pressure block 100 includes a first side plate 120, a second side plate 130 and a third side plate 140, the second side plate 130 is connected to one side of the first side plate 120 along the first direction, and the end of the second side plate 130 away from the first joint 110 protrudes from the side of the first side plate 120; the third side plate 140 is connected to the other side of the second side plate 130 along the first direction, and the end of the third side plate 140 away from the first joint 110 protrudes from the side of the first side plate 120; when the second joint is clamped in the side groove 311, the opposite sides of the first flange 3111 and the second flange 3112 respectively abut against the second side plate 130 and the third side plate 140.

[0079] The first side panel 120 is used to connect and support the second side panel 130 and the third side panel 140. By setting the end of the second side panel 130 away from the first connecting portion 110 to protrude from the side surface of the first side panel 120, and the end of the third side panel 140 away from the first connecting portion 110 to protrude from the side surface of the first side panel 120, when the first and second protrusions pass over the first and second flanges 3111 and 3112 and enter the side grooves 311, the side surfaces of the first and second flanges 3111 and 3112 can abut against the second and third side panels 130 and 140. This allows the second and third side panels 130 and 140 to limit the first and second flanges 3111 and 3112, thereby limiting the relative movement of the profile 310 and the secondary pressure block 200 in the first direction. Since the first protrusion and the second protrusion respectively abut the side surfaces of the first flange 3111 and the second flange 3112, the first protrusion and the second protrusion can limit the movement of the profile 310 in a direction perpendicular to the first direction, and at the same time limit the rotation of the profile 310 relative to the auxiliary pressure block 200, so that the profile 310 and the auxiliary pressure block 200 are more stable and reliable after being combined with each other.

[0080] As shown in Figures 1, 2, and 9 to 11, in one embodiment, the secondary pressure block 200 is fixedly connected to the first side plate 120. The secondary pressure block 200 is fixedly connected to the first side plate 120 to achieve mutual connection between the secondary pressure block 200 and the main pressure block 100. Specifically, there is no limitation on the connection method between the secondary pressure block 200 and the first side plate 120.

[0081] As shown in Figures 11 to 13, in one embodiment, the first side plate 120 is provided with a clamping hole 121 that passes through the first side plate 120 in the thickness direction; the secondary pressure block 200 is provided with two oppositely arranged limit members 230, and the ends of the two limit members 230 protrude in directions away from each other. The two limit members 230 can be deformed in a direction close to each other under the action of external force, and the two limit members 230 can pass through the clamping hole 121 from one side of the first side plate 120 to the other side of the first side plate 120 and resist each other with the first side plate 120.

[0082] By providing the locking hole 121 on the first side plate 120, and by providing two oppositely disposed limiting members 230 on the auxiliary pressure block 200, and by configuring the ends of the two limiting members 230 to protrude in a direction away from each other, when the limiting members 230 are passed through the locking hole 121, the protruding portions of the limiting members 230 can abut against the first side plate 120, thereby achieving mutual limitation between the first side plate 120 and the limiting members 230, and further achieving a fixed connection between the auxiliary pressure block 200 and the first side plate 120. The above structure has the advantages of being simple in structure and easy to install.

[0083] As shown in Figures 11 to 13, specifically, two limiting members 230 are arranged on the side of the auxiliary pressure block body 220 that faces away from the first connecting member and the second connecting member. The limiting member 230 is generally a plate-shaped structure, and the two limiting members 230 are arranged opposite each other and are generally parallel. One end of the limiting member 230 is connected to the side of the first side plate 120, and the end of the other end of the limiting member 230 protrudes in a direction away from the other limiting member 230 to mutually abut against the first side plate 120. Furthermore, the protruding portion of the limiting member 230 facing away from the side of the auxiliary pressure block body 220 is configured as an inclined surface, and the inclined surface forms an acute angle with the limiting member 230 itself. In other words, the distance between the two inclined surfaces of the two limiting members 230 gradually increases from the end away from the first side plate 120 to the end closer to the first side plate 120. In this way, when the auxiliary pressure block 200 is connected to the first side plate 120 , the inclined surface on the protrusion on the limiting member 230 can be used for guidance, thereby facilitating the limiting member 230 to be inserted into the locking hole 121 .

[0084] As shown in Figures 11 to 13, in this embodiment, the shape of the engaging hole 121 corresponds to the line connecting the projections of the two stoppers on the first side plate 120, excluding the protruding portions. For example, if the projections of the two parallel stoppers on the first side plate 120, excluding the protruding portions, are approximately rectangular, then the engaging hole 121 provided in the first side plate 120 will be rectangular. It is understood that the area of ​​the engaging hole 121 should be slightly larger than the projections of the two stoppers 230 on the first side plate 120. Of course, the area of ​​the engaging hole 121 should be smaller than the projections of the protruding portions of the stoppers 230 on the first side plate 120. The distance between the side of the protruding portion of the stopper 230 opposite the auxiliary pressure block body 220 and the auxiliary pressure block body 220 should be slightly greater than the thickness of the first side plate 120, so that the first side plate 120 can be retained between the protruding portion and the auxiliary pressure block body 220.

[0085] As shown in Figures 1, 2, and 3, in one embodiment, a mounting hole 122 extending through the thickness of the first side plate 120 is provided on the first side plate 120, and a through hole corresponding to the mounting hole 122 is provided on the secondary pressure block 200. A mounting member sequentially passes through the through hole and the mounting hole 122 to connect the secondary pressure block 200 to the first side plate 120. By providing the mounting hole 122 on the first side plate 120 and providing a through hole corresponding to the mounting hole 122 on the secondary pressure block 200, the secondary pressure block 200 and the first side plate 120 are fixedly connected by the mounting member sequentially passing through the through hole in the secondary pressure block 200 and the mounting hole 122 in the first side plate 120. Specifically, the mounting member is a rivet, and a through hole is provided on the secondary pressure block body 220 of the secondary pressure block 200. The secondary pressure block body 220 and the first side plate 120 are fixed by rivets. This arrangement has a simple structure, is easy to install, and has high reliability after connection.

[0086] As shown in Figures 3 and 13, in one embodiment, a first escape notch 132 is provided on the second side plate 130, and a second escape notch 141 is provided on the second side plate 130, with the first escape notch 132 and the second escape notch 141 corresponding to each other; the two ends of the second joint portion pass through the first escape notch 132 and the second escape notch 141, respectively, and protrude from the side surfaces away from the second side plate 130 and the third side plate 140. By providing the first escape notch 132 and the second escape notch 141 on the second side plate 130 and the third side plate 140, respectively, for circumventing the auxiliary pressure block body 220, the structural layout of the auxiliary pressure block 200 and the main pressure block 100 is more reasonable.

[0087] As shown in Figures 3 and 13, specifically, a first avoidance notch 132 and a second avoidance notch 141 are respectively provided on the second side panel 130 and the second side panel 130 at positions roughly corresponding to the mounting hole 122 or the latch hole 121 on the first side panel 120. The first avoidance notch 132 and the second avoidance notch 141 are square notches, and the bottom surfaces corresponding to the first avoidance notch 132 and the second avoidance notch 141 are roughly flush with the side surfaces of the first side panel 120. With this arrangement, when the secondary pressure block 200 is connected to the first side panel 120, the side surfaces of the secondary pressure block body 220 can abut against the first side panel 120 and the bottom surfaces of the first avoidance notch 132 and the second avoidance notch 141, thereby increasing the contact area between the secondary pressure block body 220 and the primary pressure block 100, thereby improving the stability of the two after the connection.

[0088] It should be noted that, in this application, the number of secondary pressure blocks 200 in a profile mounting assembly is not limited and can be one, two, or more. In this embodiment, as shown in Figures 9 and 11, two spaced-apart secondary pressure blocks 200 are provided on a primary pressure block 100 to increase the contact area between the secondary pressure blocks 200 and the profile 310, thereby improving the strength of the profile 310 and the profile mounting assembly after connection.

[0089] As shown in Figures 3 and 13, in one embodiment, the main pressure block 100 also includes a fourth side plate 150 and a fifth side plate 160, one end of the fourth side plate 150 is connected to the side of the first side plate 120 away from the third side plate 140, and the fourth side plate 150 and the second side plate 130 are arranged opposite to each other in the first direction; the fifth side plate 160 is connected to the second side plate 130 and the end of the fourth side plate 150 away from the first side plate 120, and the two ends of the fifth side plate 160 along the first direction respectively protrude from the sides of the second side plate 130 and the fourth side plate 150 away from each other to engage with the side groove 311. A frame structure is formed by the first side panel 120, the second side panel 130, the fourth side panel 150, and the fifth side panel 160. The ends of the second side panel 130 along the first direction are arranged to protrude from the side surfaces of the second and fourth side panels 130, 150 that are away from each other, so that the protruding portions of the fifth side panel 160 can engage with the side grooves 311 on the profile 310. The second, fourth, and fifth side panels 130, 150, and 160, when connected, form the first connecting portion 110 described above.

[0090] As shown in FIG3 and FIG13 , in one embodiment, a first limiting groove 131 and a second limiting groove 151 are respectively provided on the side surfaces of the second side panel 130 and the fourth side panel 150 that are away from each other. A first flange 3111 and a second flange 3112 are respectively provided in the first limiting groove 131 and the second limiting groove 151. The side surfaces at both ends of the fifth side panel 160 are configured as groove sidewalls of the first limiting groove 131 and the second limiting groove 151. By providing the first limiting groove 131 and the second limiting groove 151 on the side surfaces of the second side panel 130 and the fourth side panel 150 that are away from each other, the first flange 3111 and the second flange 3112 on the profile 310 are accommodated, thereby achieving position limiting of the first flange 3111 and the second flange 3112.

[0091] As shown in Figures 3 and 13, specifically, the two ends of the fifth side panel 160 are configured as the side walls of the first limiting groove 131 and the second limiting groove 151 facing the side of the first side panel 120, so that when the two ends of the fifth side panel 160 respectively pass over the first flange 3111 and the second flange 3112 and enter the first limiting groove 131 and the second limiting groove 151, the side of the fifth side panel 160 can resist the first flange 3111 and the second flange 3112, and accordingly, the two ends of the fifth side panel 160 are respectively clamped in the side groove 311.

[0092] It is worth mentioning that in this embodiment, as shown in Figures 3 and 13, the first limiting groove 131 is formed by the end of the fifth side plate 160, the second side plate 130, and a rib 133 connected to the second side plate 130 and spaced apart from the fifth side plate 160. The second limiting groove 151 is configured by recessing the end of the fourth side plate 150 toward the second side plate 130, and the recessed portion and the end of the fifth side plate 160 enclose and define the second limiting groove 151.

[0093] In one embodiment, as shown in Figures 3 and 13 , the main clamp 100 is provided with a connection hole 134, through which a fastener is passed to securely connect with the bracket. By providing the connection hole 134 on the main clamp 100, the main clamp 100 is securely connected to the bracket via the fastener, thereby securing the profile 310 to the bracket. Specifically, the connection hole 134 is provided midway between the second side panel 130 and the fourth side panel 150 of the main clamp 100. The connection holes 134 on the two side panels correspond to each other, facilitating the fastener's passage through the connection hole 134 to secure the bracket.

[0094] As shown in Figures 14 to 16, an embodiment of the present application also provides a photovoltaic system, including multiple profiles 310 and brackets, each profile 310 has a support portion 312 for carrying a workpiece to be installed, and each profile 310 has a side groove 311, and at least one profile mounting assembly is installed on the side groove 311, and the profile mounting assembly is fixedly connected to the bracket.

[0095] By fixing the profile mounting assembly to the bracket, the profile 310 is installed and combined with the profile mounting assembly to achieve a fixed connection between the profile 310 and the bracket. The support portion 312 on the profile 310 is used to support and fix the photovoltaic module, thereby achieving mutual connection between the photovoltaic module and the bracket. In this way, a photovoltaic system is formed. Specifically, two parallel purlins are provided on the bracket, and the main pressure block 100 in the profile mounting assembly is fixedly connected to the purlins by fasteners, such as bolts. The profile 310 is the frame of the photovoltaic module, and the profile 310 is provided on all four sides of the photovoltaic module. Generally, the profile 310 corresponding to the long side of the photovoltaic module is fixedly connected to the bracket via the profile mounting assembly. The profiles 310 of two adjacent photovoltaic modules are respectively combined with the first coupling portion 110 on the main pressure block 100 and the second coupling portion on the secondary pressure block 200, so that the two adjacent photovoltaic modules can be installed on the bracket via the profile mounting assembly.

[0096] Referring to Figure 17 , Figure 17 shows a flowchart of a photovoltaic system installation method according to one embodiment of the present application. It should be understood that although the steps in the flowchart shown in Figure 17 are shown sequentially as indicated by the arrows, these steps are not necessarily performed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction for the execution of these steps and they may be performed in other orders. Furthermore, at least some of the steps in Figure 17 may include multiple sub-steps or multiple stages. These sub-steps or stages do not necessarily need to be completed at the same time, but may be performed at different times. Their execution order does not necessarily need to be performed all at once, but may be performed in rotation or alternation with other steps or at least a portion of their sub-steps or stages. One embodiment of the present application provides a photovoltaic system installation method, comprising the following steps: installing the first coupling portion 110 of the profile mounting assembly described above into the side groove 311 of one profile; mounting the profile mounting assembly on a bracket using fasteners; and engaging the side groove 311 of another profile with the second coupling portion of the profile mounting assembly.

[0097] Specifically, the first engaging portion 110 of a profile mounting assembly is first installed in the side groove 311 of a profile containing a photovoltaic module. The end of the fifth side plate 160 on the main pressure block 100 in the profile mounting assembly, which protrudes from the second side plate 130, is first inserted into the side groove 311 of the profile. The profile mounting assembly is then rotated a certain angle so that the end of the fifth side plate 160 protruding from the fourth side plate 150 passes over the side groove 311 of the profile and is inserted into the side groove 311. This completes the engagement of the profile mounting assembly with the profile of one of the photovoltaic modules.

[0098] Then, the profile mounting assembly is fixed to the bracket by fasteners, thus achieving a fixed connection between the profile and the bracket on one side of a photovoltaic module.

[0099] Then, the profile of another photovoltaic module is aligned with the second fixing portion of the secondary pressure block 200 on the profile mounting assembly already fixed to the bracket. By pushing the photovoltaic module toward the second fixing portion, the mouth of the side groove 311 in the profile of the photovoltaic module is guided by the inclined surface of the second fixing portion and engages with the second fixing portion. This achieves a fixed connection between the other photovoltaic module and the bracket.

[0100] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
