Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and 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 of this utility model.

[0032] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0033] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0034] Existing photovoltaic modules (210) mostly adopt a frame structure with an A-side frame. An aluminum alloy frame is used to ensure mechanical strength. During installation, metal clamps (130) and bolts (121) are used to connect the frame to the supporting structure. Because mechanical stress needs to be distributed, the traditional frame clamping plane is relatively wide. However, this design has two major limitations: first, dust easily accumulates on the A-side frame, affecting the module's light-receiving efficiency; second, the wide frame results in a large module spacing, reducing land utilization and increasing the complexity of electrical connections.

[0035] To address the dust accumulation issue, the industry has introduced frameless A-side designs, improving the self-cleaning performance of the components. However, when frameless components are used with conventional pressure blocks 130, the lack of a stress-dispersing structure means the load from the pressure block 130 acts directly on the glass surface. Under wind pressure and temperature stress, this can easily lead to micro-cracks or even breakage in the glass. Existing improvements to the pressure block 130 structure and optimization measures such as adding buffer pads have not completely resolved the contradiction between stress concentration and installation reliability.

[0036] To solve the above problems, please refer to... Figures 1-3 This utility model provides a photovoltaic mounting component 100, which includes two photovoltaic frames 110 and two fasteners 120; each photovoltaic frame 110 corresponds to one fastener 120, that is, each photovoltaic frame 110 is connected to the bracket 220 through the corresponding fastener 120.

[0037] In this embodiment, each photovoltaic frame 110 has a first through hole 111, an elongated hole 112, and a second through hole 113 connected in sequence on the side for connection with the bracket 220, and each photovoltaic frame 110 also has a clearance groove 114; wherein the first through hole 111, the elongated hole 112, and the second through hole 113 are all connected to the clearance groove 114, and the projected area of ​​the first through hole 111 is larger than the projected area of ​​the second through hole 113. It can be understood that the fastener 120 can enter the clearance groove 114 through the first through hole 111, and then move sequentially along the extension direction of the elongated hole 112, thereby moving from the first through hole 111 to the second through hole 113. Subsequently, since the projection of the second through hole 113 is located within the fastener 120, the fastener 120 can abut against the edge of the second through hole 113, thereby preventing the fastener 120 from moving and preventing the fastener 120 from moving out of the clearance groove 114, thus improving the stability of the installation.

[0038] In this embodiment, both the first through hole 111 and the second through hole 113 are circular holes, so the diameter of the first through hole 111 is larger than the diameter of the second through hole 113. The fastener 120 includes a bolt 121, so the diameter of the nut in the bolt 121 is smaller than the diameter of the first through hole 111 but larger than the diameter of the second through hole 113. This allows the nut of the bolt 121 to enter the clearance groove 114 through the first through hole 111 and abut against the edge of the second through hole 113. In other embodiments, the first through hole 111 and the second through hole 113 can also be configured in other shapes, which can be adjusted according to actual conditions.

[0039] It should be noted that in this embodiment, the sidewalls of the two photovoltaic frames 110 abut against each other, making the gap between the two photovoltaic frames 110 extremely small or even non-existent. This allows for the assembly of more photovoltaic modules 210 within a given space, improving space utilization and thus increasing power generation and efficiency. Furthermore, because the gap between the two photovoltaic frames 110 is extremely small, the relative displacement between the photovoltaic frames 110 and the photovoltaic modules 210 can be limited, thereby dispersing stress over a wider area and resulting in higher stability and better resistance to external forces.

[0040] Because the sidewalls of the two photovoltaic frames 110 abut together, the clearance grooves 114 of the two photovoltaic frames 110 can enclose and form a closed chamber 101, thereby further improving the stability of the photovoltaic mounting module 100 structure. Furthermore, the clearance grooves 114 provide installation space without gaps between the two photovoltaic frames 110, facilitating the installation of the fastener 120. It should be noted that when the fastener 120 passes through the photovoltaic frames 110, it first abuts against the bracket 220. After the fastener 120 abuts against the second through hole 113, the bracket 220 and the photovoltaic frame 110 can be installed together through the fastener 120. Understandably, after installation, a portion of the fastener 120 is located within the closed chamber 101 to prevent external forces from affecting the fastener 120.

[0041] Furthermore, in this embodiment, the photovoltaic mounting assembly 100 also includes a pressure block 130, which is housed in a cavity 101 formed by two clearance grooves 114. The photovoltaic frame 110 and the bracket 220 are mounted together by connecting the pressure block 130 with the fixing member 120.

[0042] Specifically, the pressure block 130 is first placed in the two clearance slots 114, and then the two photovoltaic frames 110 are brought close together to abut against each other, forming a closed cavity 101, so that the pressure block 130 is accommodated within the cavity 101. Subsequently, the fixing member 120 is passed through the through hole on the photovoltaic frame 110 to connect the fixing member 120 and the pressure block 130 together. It should be noted that during the process of connecting the pressure block 130, the fixing member 120 is first connected to the bracket 220, so that after the fixing member 120 and the pressure block 130 are connected together, the bracket 220 is also connected to the photovoltaic frame 110.

[0043] This embodiment provides counterweight by incorporating a pressure block 130 housed within the chamber 101, thereby increasing the weight of the photovoltaic mounting module 100 and resisting external forces, thus improving installation stability. Since the pressure block 130 is located within the enclosed chamber 101, it is also protected from the influence of external forces.

[0044] According to the above, the fastener 120 in this embodiment includes a bolt 121. Correspondingly, the pressure block 130 is provided with two threaded holes to thread each bolt 121 and a threaded hole to connect the fastener 120 and the pressure block 130 together.

[0045] It should be noted that in this embodiment, the length L of the pressure block 130 is equal to the sum of the groove depth H of the two relief grooves 114, that is, L=2H; therefore, after the two relief grooves 114 are combined, the pressure block 130 will abut against the bottom of the relief groove 114, so that the two threaded holes can be directly opposite the two second through holes 113 respectively.

[0046] Specifically, after the pressure block 130 is placed in the chamber 101, the two threaded holes of the pressure block 130 are respectively aligned with the second through hole 113 of a photovoltaic frame 110; then, after the nuts of the two bolts 121 are held together with the bracket 220, the other end of each bolt 121 passes through the corresponding second through hole 113 and engages with the corresponding threaded hole, thereby realizing the connection between the bracket 220 and the photovoltaic frame 110.

[0047] Alternatively, one threaded hole can be aligned with a second through hole 113, and a bolt 121 can be passed through the second through hole 113 to be threadedly connected to the corresponding threaded hole. Then, the pressure block 130 located outside the clearance groove 114 is placed in the clearance groove 114 of another photovoltaic frame 110, so that the two photovoltaic frames 110 are close to each other to form a closed chamber 101. The other bolt 121 hole of the pressure block 130 is aligned with another second through hole 113. Finally, the other bolt 121 is connected to the pressure block 130, thereby installing the photovoltaic frame 110 and the bracket 220.

[0048] Understandably, the diameter of the nut of bolt 121 is larger than the diameter of the second through hole 113, while the diameter of the bolt shank of bolt 121 is smaller than the diameter of the second through hole 113. Therefore, after the pressure block 130 is installed, the bolt shank can be directly passed through the second through hole 113 to connect the pressure block 130.

[0049] In this embodiment, the bracket 220 is provided with a through hole for the screw to pass through. The screw first passes through the through hole of the bracket 220, then through the second through hole 113, and then is threaded into the threaded hole. During the threaded connection, the nut directly abuts against the screw to achieve the installation of the photovoltaic frame 110 and the bracket 220. The diameter of the through hole on the bracket 220 is larger than the diameter of the screw and smaller than the diameter of the nut.

[0050] It should be noted that, please refer to Figure 2 and Figure 5The extension direction of the elongated hole 112 can be parallel or perpendicular to the extension direction of the photovoltaic frame 110. Similarly, the directions in which the first through hole 111, the elongated hole 112, and the second through hole 113 in the two photovoltaic frames 110 are connected can be the same or opposite. Specifically, if the directions in which the first through hole 111, the elongated hole 112, and the second through hole 113 in the two photovoltaic frames 110 are connected are the same, then the distance between the two first through holes 111 and the distance between the two second through holes 113 are the same; if the directions in which the first through hole 111, the elongated hole 112, and the second through hole 113 in the two photovoltaic frames 110 are connected are opposite, then the distance between the two first through holes 111 and the distance between the two second through holes 113 are not the same.

[0051] Therefore, depending on the different setup methods, different types of pressure blocks 130 need to be set so that the two threaded holes of the pressure block 130 can be aligned with the two second through holes 113.

[0052] Please refer to Figure 4 To improve versatility, in other embodiments, the photovoltaic mounting assembly 100 does not include the pressure block 130, while the fastener 120 includes a bolt 121 and a nut 122. Since the diameter of the nut of the bolt 121 is smaller than the diameter of the first through hole 111, the nut of the bolt 121 can pass through the first through hole 111 and enter the clearance groove 114. Subsequently, the bolt 121 moves along the extension direction of the elongated hole 112 from the first through hole 111 to the second through hole 113. Because the diameter of the nut is larger than the diameter of the second through hole 113, the nut can abut against the edge of the second through hole 113. Finally, the nut 122 is threaded onto the bolt 121, and the nut 122 abuts against the bracket 220. Thus, after the threaded engagement, the photovoltaic frame 110 and the bracket 220 can be installed together.

[0053] Bolt 121, nut 122 and bracket 220 can also be connected together by threaded connection, and the nut of bolt 121 is held against the edge of second through hole 113 so that bracket 220 and photovoltaic frame 110 are connected together.

[0054] Understandably, the bracket 220 is provided with a through hole through which the screw can pass, so that the screw can pass through the through hole, and after the bolt 121 and the nut 122 are threaded together, the nut 122 can abut against the bracket 220; the diameter of the screw is smaller than the diameter of the through hole, while the diameter of the nut 122 is larger than the diameter of the through hole.

[0055] It should be noted that if the first through hole 111, the elongated hole 112, and the second through hole 113 in the two photovoltaic frames 110 are connected in the same direction, the two photovoltaic frames 110 can be held together first, so that the two clearance grooves 114 are merged. Then, the nut of each bolt 121 is inserted into the cavity 101 formed by the two clearance grooves 114 through the corresponding first through hole 111. The two bolts 121 are then moved in the same direction, so that the bolts 121 abut against the edge of the corresponding second through hole 113. Finally, the connecting nut 122 is used to install the photovoltaic frame 110 and the bracket 220 together.

[0056] If the first through hole 111, the elongated hole 112, and the second through hole 113 in the two photovoltaic frames 110 are connected in opposite directions, and the distance between the two first through holes 111 is less than the distance between the two second through holes 113, then a photovoltaic frame 110 and a bracket 220 can be installed together first by a fastener 120. Then, the nut of another bolt 121 is passed through the corresponding first through hole 111. Next, the photovoltaic frames 110 are moved so that the two photovoltaic frames 110 abut together. At the same time, the nut is moved to the second through hole 113 and abuts against the edge of the second through hole 113. Finally, the bolt 121 is threaded together with the nut 122 to complete the installation.

[0057] It should be noted that the above installation method is used to fix the frames of two photovoltaic modules 210 at the same time, that is, the photovoltaic mounting component 100 is installed between the two photovoltaic modules 210; if it is necessary to install the outermost photovoltaic frame 110, since there is only one photovoltaic frame 110, only one fastener 120 is used to connect the photovoltaic frame 110 and the bracket 220.

[0058] Furthermore, in this embodiment, each photovoltaic frame 110 has a mounting groove 115 on the side away from the clearance groove 114, wherein the opening direction of the clearance groove 114 is opposite to the opening direction of the mounting groove 115. Understandably, the photovoltaic frame 110 is provided with mounting grooves 115 to mount the photovoltaic module 210. To avoid interference between the photovoltaic module 210 and the two photovoltaic frames 110, allowing them to abut together, and to ensure that the two clearance grooves 114 form a closed chamber 101, the opening directions of the mounting groove 115 and the clearance groove 114 must be opposite. Thus, the photovoltaic module 210 and the bracket 220 can be mounted together through the photovoltaic frame 110.

[0059] Furthermore, in this embodiment, to improve installation stability, an anti-slip part 116 is also provided in the mounting groove 115. The photovoltaic module 210 contacts the anti-slip part 116, thereby increasing friction and preventing the photovoltaic module 210 from detaching from the photovoltaic frame 110. Specifically, the anti-slip part 116 can be multiple anti-slip protrusions, making the surface in contact with the photovoltaic module 210 in the mounting groove 115 uneven, thereby increasing friction.

[0060] According to the above, each photovoltaic frame 110 is provided with a cavity 117 to disperse stress and improve the stability of installation. In addition, the photovoltaic frame 110 is also provided with a reinforcing rib 118. In order to avoid the two photovoltaic frames 110 from not being able to hold together due to the influence of the reinforcing rib 118, the reinforcing rib 118 is provided in the cavity 117 in this embodiment.

[0061] In summary, this embodiment provides a photovoltaic mounting assembly 100, which includes two photovoltaic frames 110 and two fasteners 120. The two photovoltaic frames 110 are held together, thereby reducing or eliminating the gap between them to distribute stress and improve stability. This also increases space utilization and improves power generation and efficiency. Each photovoltaic frame 110 in this embodiment is provided with a clearance groove 114 to facilitate the installation of the fasteners 120, thus connecting the photovoltaic frame 110 and the bracket 220 using the fasteners 120. When the two photovoltaic frames 110 are held together, the two clearance grooves 114 enclose a closed chamber 101 to resist external forces, thereby improving stability. Furthermore, each photovoltaic frame 110 is also provided with a first through hole 111, an elongated hole 112 and a second through hole 113, so that the fastener 120 can enter from the first through hole 111 and then move to the second through hole 113 to abut against the edge of the second through hole 113, thereby improving the convenience of installation.

[0062] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
