Detailed Implementation

[0035] 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.

[0037] 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.

[0038] 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.

[0039] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0040] 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.

[0041] Please refer to Figure 1 and Figure 2 This utility model provides a photovoltaic mounting component 200, which includes a pressure block 210 and a photovoltaic frame 100. The pressure block 210 includes a connecting part 211, a first mating part 212 and a second mating part 213 connected in sequence. The connecting part 211 is connected to a bracket, while the first mating part 212 and the second mating part 213 are both connected to the photovoltaic frame 100.

[0042] It should be noted that when installing photovoltaic modules, multiple photovoltaic module arrays need to be arranged on the bracket to install the photovoltaic modules, and each photovoltaic module is connected to a photovoltaic frame 100 at its edge. In order to install the photovoltaic modules on the bracket, the photovoltaic frame 100 is connected by a pressure block 210, thereby connecting the photovoltaic frame 100 to the bracket and installing the photovoltaic modules on the bracket.

[0043] Please refer to Figure 3 and Figure 4If the photovoltaic mounting module 200 includes two photovoltaic frames 100, then the pressure block 210 is located between the two photovoltaic frames 100, that is, the pressure block 210 is the middle pressure block 210. The connecting portion 211 has mating portions connected to both opposite sides, with one mating portion on one side corresponding to one photovoltaic frame 100. If the photovoltaic mounting module 200 includes only one photovoltaic frame 100, then the pressure block 210 is the side pressure block 210, and the mating portion is located on one side of the connecting portion 211.

[0044] The connecting part 211 has a through hole, and the photovoltaic mounting assembly 200 also includes screws 220, so that the screws 220 can pass through the through hole and be threadedly connected to the bracket. After the pressure block 210 is connected to the bracket by the screws 220, the connecting part 211 abuts against the bracket, and the bottom wall 122 and extension of the photovoltaic frame 100 also abut against the bracket to increase the contact area, improve installation stability, and prevent shaking or falling off due to external forces such as strong winds.

[0045] In this embodiment, the photovoltaic frame 100 includes an assembly part 110, an extension part, and a main body 120. The main body 120 includes a top wall 121, a bottom wall 122, an inner side wall 123, and an outer side wall 124. The top wall 121, bottom wall 122, inner side wall 123, and outer side wall 124 are connected end to end to enclose and form a cavity 103. It can be understood that the photovoltaic module has a square structure, so each photovoltaic module is equipped with four photovoltaic frames 100. Two adjacent photovoltaic frames 100 are connected together by corner brackets. The corner brackets extend into the cavity 103 and are thus connected to the photovoltaic frame 100.

[0046] Specifically, the assembly part 110 is connected to the junction of the top wall 121 and the outer wall 124, and the extension part is connected to the junction of the bottom wall 122 and the inner wall 123. The assembly part 110 and the top wall 121 cooperate to form an assembly groove 104, in which the photovoltaic module is placed and abuts against the assembly part 110. Furthermore, the top wall 121 has an adhesive storage groove 105, which communicates with the assembly groove 104. Adhesive is injected into the adhesive storage groove 105, thereby using the adhesive to bond the top wall 121 of the photovoltaic frame 100 and the photovoltaic module together, improving installation stability and preventing the photovoltaic module from falling off.

[0047] In this embodiment, the mounting part 110 abuts against the side of the photovoltaic module, thereby preventing the mounting part 110 from blocking the light-facing surface of the photovoltaic module and affecting the power generation and efficiency of the photovoltaic module. The extension part is located inside the photovoltaic frame 100 and extends away from the photovoltaic frame 100, and the extension direction of the extension part is parallel to the photovoltaic module.

[0048] It should be noted that the outer wall 124 is provided with a receiving groove 101 and a snap-fit ​​groove 102, and the recessed direction of the receiving groove 101 and the recessed direction of the snap-fit ​​groove 102 are perpendicular to each other. It can be understood that the recessed direction of the receiving groove 101 is parallel to the extension direction of the extension, and the recessed direction of the snap-fit ​​groove 102 is perpendicular to the extension direction of the extension; that is, the recessed direction of the receiving groove 101 is horizontal, thereby enabling the mating part of the pressure block 210 to extend horizontally into the receiving groove 101.

[0049] In this embodiment, the first mating part 212 is accommodated in the accommodating groove 101, while the second mating part 213 is engaged in the engaging groove 102; it can be understood that the first mating part 212 and the second mating part 213 are perpendicular to each other so as to correspond to the accommodating groove 101 and the engaging groove 102.

[0050] Therefore, by utilizing the connection between the receiving groove 101 and the snap-fit ​​groove 102 between the first mating part 212 and the second mating part 213, the pressure block 210 and the photovoltaic frame 100 are installed together; thereby improving installation stability and replacing the existing technology of connecting by pressing from above the photovoltaic module, avoiding shading of the photovoltaic module, and thus improving the power generation and power generation efficiency of the photovoltaic module.

[0051] It should be noted that the volume of the receiving groove 101 in this embodiment is greater than the volume of the first mating part 212 and the second mating part 213, so that both the first mating part 212 and the second mating part 213 can enter the receiving groove 101. Then, by moving, the second mating part 213 enters the snap-fit ​​groove 102, while the first mating part 212 remains in the receiving groove 101, thereby realizing the snap-fit ​​of the pressure block 210 and the photovoltaic frame 100 together.

[0052] For details, please refer to Figure 1 and Figure 2 The groove depth of the receiving part is H1, the height of the receiving part in the vertical direction is H2, the length of the first mating part 212 is L1, and the length of the second mating part 213 is L2; ​​wherein, H1 > L1, H2 > L2.

[0053] In this embodiment, the volume of the receiving groove 101 is larger than the volume of the snap-fit ​​groove 102. Please refer to... Figure 5 In other embodiments, the volume of the receiving groove 101 may also be smaller than the volume of the snap-fit ​​groove 102, and can be adjusted according to the actual situation.

[0054] Based on the above, in this embodiment, there are two receiving grooves 101 and two snap-fit ​​grooves 102. The two receiving grooves 101 have the same concave direction, while the two snap-fit ​​grooves 102 have opposite concave directions, so that the two receiving grooves 101 and snap-fit ​​grooves 102 are combined together to form a C shape.

[0055] Understandably, if the pressure block 210 is a middle pressure block 210, it is provided with four first mating parts 212 and two mating parts 213; if the pressure block 210 is an edge pressure block 210, it is provided with two first mating parts 212 and two mating parts 213. The two first mating parts 212 connected to the same photovoltaic frame 100 extend in the same direction, while the second mating parts 213 extend in opposite directions to adapt to the two receiving grooves 101 and the two snap-fit ​​grooves 102. In this embodiment, the two C-shaped first mating parts 212 and two second mating parts 213 can provide clamping force and improve stability.

[0056] It should be noted that in this embodiment, the material of the pressure block 210 is ABS plastic. ABS plastic is made through multiple processes such as emulsion polymerization, graft copolymerization, and physical blending. It has elasticity, which allows the two second mating parts 213 to move closer or further apart during installation, thereby being installed into the two snap-fit ​​grooves 102 respectively. Furthermore, ABS plastic also has high impact resistance, good fatigue resistance, and weather resistance. In addition, the photovoltaic frame 100 is made of aluminum alloy, which further increases the installation stability and avoids shaking or detachment caused by external forces such as strong winds.

[0057] Please refer to Figure 6 In other embodiments, the recesses of the two snap-fit ​​grooves 102 may be in the same direction, which makes it more convenient to install the pressure block 210.

[0058] Furthermore, in this embodiment, the photovoltaic frame 100 also includes a support rod 130, the two ends of which are connected to the inner sidewall 123 and the outer sidewall 124 respectively, thereby dividing the cavity 103 into three parts. It should be noted that, since the outer sidewall 124 in this embodiment is provided with a receiving groove 101 and a snap-fit ​​groove 102, which are recessed in the direction of the inner sidewall 123, the reinforcing rib 140 is connected to the portion of the outer sidewall 124 that forms the receiving groove 101 and the snap-fit ​​groove 102.

[0059] Please refer to Figure 7 In other embodiments, two support rods 130 can be provided. The two ends of one support rod 130 are connected to the outer wall 124 and the bottom wall 122 respectively, and the two ends of the other support rod 130 are connected to the outer wall 124 and the inner wall 123 respectively, thereby dividing the cavity 103 into three parts.

[0060] Please refer to Figure 8In other embodiments, only reinforcing ribs 140, whose two ends are respectively connected to the outer side wall 124 and the bottom wall 122, can be provided to divide the cavity 103 into two parts. Understandably, in this embodiment, the support rod 130 is perpendicular to the bottom wall 122, while in this application, the support rod 130 is parallel to the bottom wall 122.

[0061] Please refer to Figure 9 In other embodiments, the support rod 130 may not be provided, so that the cavity 103 is not divided.

[0062] According to the above, the photovoltaic frame 100 in this embodiment also includes at least one reinforcing rib 140. The reinforcing rib 140 is located in the cavity 103, and one or more of the top wall 121, bottom wall 122, inner side wall 123 and outer side wall 124 are connected to the reinforcing rib 140; so as to improve the structural strength of the photovoltaic frame 100, make the structure of the photovoltaic frame 100 more stable, avoid it from shaking under the influence of external forces such as strong wind, and enable installation stability.

[0063] It should be noted that the photovoltaic frame 100 in this embodiment and the photovoltaic frame 100 in other embodiments can be manufactured by injection molding or die casting.

[0064] In summary, the photovoltaic frame 100 and photovoltaic mounting assembly 200 provided in this embodiment improve installation stability by having interconnected receiving grooves 101 and snap-fit ​​grooves 102 on the outer side wall 124 of the main body 120, with the recessed directions of the two being perpendicular to each other. This allows the photovoltaic frame 100 to snap into the pressure block 210 via the snap-fit ​​grooves 102. Furthermore, the pressure block 210, connected within the receiving grooves 101 and snap-fit ​​grooves 102 of the outer side wall 124, prevents the pressure block 210 from pressing down on the photovoltaic frame 100 and photovoltaic assembly from above, thereby avoiding shading of the photovoltaic assembly and improving the power generation and efficiency of the photovoltaic assembly. This embodiment also uses an assembly part 110 to install the photovoltaic assembly, thereby using the pressure block 210 and the photovoltaic frame 100 to install the photovoltaic assembly onto the bracket. In this embodiment, the main body 120 is connected end to end by the top wall 121, bottom wall 122, outer side wall 124 and inner side wall 123 to form a cavity 103, thereby improving the structural strength of the photovoltaic frame 100 and preventing the photovoltaic frame 100 from shaking under the influence of external forces after installation.

[0065] 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.
