[0002] This application claims priority to Chinese patent application number 2023116882152, filed on December 11, 2023, entitled “Block Kit and Photovoltaic Module Mounting Structure,” the entire text of which is hereby incorporated by reference. Technical Field

[0003] The present application relates to the technical field of photovoltaic modules, and in particular to a pressing block kit and a photovoltaic module installation structure. Background Art

[0004] Photovoltaic modules are assembled by securing laminated components, including solar cells, to the module frame. Existing photovoltaic modules often utilize a side-mounted installation method to reduce stress on the glass in the module laminate. This method utilizes the frame's side grooves and a corresponding clamping block for quick side-mounting. However, in related technologies, this side-mounting process requires the clamping block to be flipped or tilted relative to the frame to create a specific installation angle so that the frame's side grooves align with the clamping block for insertion, making installation of the photovoltaic module frame somewhat difficult.

[0038] The details of one or more embodiments of the disclosure are set forth in the accompanying drawings and the description below.

[0039] Referring to Figures 1, 2, and 3, Figure 1 is a schematic diagram of a pressure block assembly provided in one embodiment of the present application. Figure 2 is a front view of a pressure block assembly provided in one embodiment of the present application. Figure 3 is a schematic diagram of a pressure block assembly in a pressure block assembly provided in one embodiment of the present application being engaged with a side groove of a frame. An embodiment of the present application provides a pressure block kit, including a fastener 200 and a pressure block assembly 100; the fastener 200 is used to be connected to the purlin 500; the pressure block assembly 100 includes a first pressure block 110 and a second pressure block 120, both of which are sleeved on the fastener 200, and the first pressure block 110 and the second pressure block 120 are respectively used to engage with a group of first groove walls of the side groove 410 of the frame 400 that are opposite to each other along a first direction, so as to limit the frame 400 to the purlin 500; wherein the fastener 200 is configured to enable the first pressure block 110 and the second pressure block 120 to approach or move away from each other in the first direction, so that the first pressure block 110 and the second pressure block 120 are engaged with or disengaged from the two first groove walls; the first direction is along the extension direction of the fastener 200.

[0040] The clamping block kit in this application is used in a photovoltaic module mounting structure, which also includes a frame 400. The frame 400 is provided with side grooves 410. The frame 400 engages with the clamping block kit through the side grooves 410 to be retained on the purlin 500. The side of the frame 400 facing away from the side grooves 410 is provided with a mounting groove 420 for inserting the photovoltaic module, thereby fixing the photovoltaic module to the purlin 500.

[0041] The present application provides a pressure block kit. Specifically, the fastener 200 in the present application is connected to the purlin 500, and the first pressure block 110 and the second pressure block 120 are both sleeved on the fastener 200. The first pressure block 110 and the second pressure block 120 are moved closer to or farther away from each other in the first direction, so that the first pressure block 110 and the second pressure block 120 can be inserted into the side groove 410 of the frame 400 to engage with the two first groove walls, thereby limiting the frame 400 on the purlin 500 and limiting the pressure block assembly 100 from being dislodged from the side groove 410. That is, the pressure block kit in the present application does not need to be flipped or tilted to be plugged into the side groove 410 of the frame 400 to achieve the engaging engagement of the pressure block assembly 100 with the side groove 410 of the frame 400, so as to limit the frame 400 to the purlin 500, thereby improving the convenience and efficiency of installation.

[0042] It should be noted that, taking FIG1 of the specification as an example, XX' is defined as the first direction, YY' is the second direction, and ZZ' is the third direction. The following description is based on the first direction, the second direction, and the third direction.

[0043] Referring to Figures 1, 3, and 4, Figure 4 is a schematic diagram of a first pressing block in a pressing block kit according to one embodiment of the present application. In one embodiment, the first pressing block 110 includes a first pressing plate 111 and a first extension 112. The first pressing plate 111 is sleeved on the fastener 200, and the first extension 112 is protruding from one side of the first pressing plate 111 along a first direction. The first extension 112 is configured to press against one of the first groove walls of the side groove 410 to tighten the frame 400 against the purlin 500.

[0044] Specifically, the first extension portion 112 is configured to extend into the side groove 410 of the frame 400. By operating the fastener 200, when the first pressing block 110 and the second pressing block 120 move away from or toward each other in the first direction, the first extension portion 112 can move toward the purlin 500, thereby abutting against the first groove wall of the side groove 410 of the frame 400 near the purlin 500. The push of the first extension portion 112 allows the outer wall of the frame 400 to abut against the purlin 500, thereby restricting the frame 400 to the purlin 500. In the present application, the first extension portion 112 cooperates with the purlin 500 to clamp the first groove wall of the side groove 410 of the frame 400, thereby stably mounting the frame 400 on the purlin 500, reducing the number of components, simplifying the structure, and improving operational convenience. Preferably, the first pressing plate 111 is perpendicular to the first direction.

[0045] For the convenience of description, a first groove wall close to the purlin 500 is defined as a lower groove wall 411 , and another first groove wall away from the purlin 500 is defined as an upper groove wall 412 .

[0046] Furthermore, the lower groove wall 411 includes a first section and a second section that are connected to each other. The first section corresponds to the purlin 500, and the second section is located on the side of the notch near the side groove 410 and is arranged toward the upper groove wall 412. The end of the first extension 112 abuts the first section, thereby applying a thrust toward the purlin 500 to the first section. This allows the first extension 112 to cooperate with the purlin 500, clamping the frame 400 and retaining the frame 400 on the purlin 500. The provision of the second section can limit the first extension 112, preventing the first pressure block 110 from disengaging from the side groove 410, thereby ensuring stable pressure contact between the first extension 112 and the first section, thereby improving the reliability of the pressure block assembly.

[0047] Referring to Figures 1, 3, 4, and 5, Figure 5 is a schematic diagram of a second pressure block in a pressure block assembly provided in one embodiment of the present application. In one embodiment, the second pressure block 120 includes a second pressure plate 121 and a second extension 122. The second pressure plate 121 is sleeved on the fastener 200, and the second extension 122 is protruding from one side of the second pressure plate 121 facing the first direction. The second extension 122 is configured to engage with the other first groove wall of the side groove 410 to prevent the second pressure block 120 from being dislodged from the side groove 410.

[0048] Specifically, the second extension portion 122 is configured to extend into the side groove 410 of the frame 400. By operating the fastener 200, when the first pressing block 110 and the second pressing block 120 move away from or toward each other in the first direction, the second extension portion 122 can move toward the upper groove wall 412, thereby enabling the second extension portion 122 to engage with the upper groove wall 412 to restrict the second pressing block 120 from being dislodged from the side groove 410 of the frame 400. This ensures that the first pressing block 110 and the second pressing block 120 are stably engaged with the side groove 410 of the frame 400, thereby stably securing the frame 400 on the purlin 500. Preferably, the second pressing plate 121 is perpendicular to the first direction.

[0049] Furthermore, the upper groove wall 412 includes a third section and a fourth section that are connected to each other. The third section is arranged opposite the first section along the first direction, and the fourth section is located at the notch of the side groove 410 and is arranged toward the first section. The end of the second extension 122 is used to hook with the fourth section, thereby limiting the distance between the frame 400 and the fastener 200, thereby stably limiting the separation of the second pressing block 120 from the side groove 410, so that the first pressing block 110 is stably pressed against the lower groove wall 411 of the side groove 410 of the frame 400, thereby stably restraining the frame 400 on the purlin 500.

[0050] 1 , 2 , and 3 , in one embodiment, the first extension portion 112 and the second extension portion 122 are located on opposite sides of the first pressing plate 111 and the second pressing plate 121 , and one of the first pressing block 110 and the second pressing block 120 is provided with an escape hole, and the other of the first pressing block 110 and the second pressing block 120 is partially passed through the escape hole, so that the first pressing block 110 and the second pressing block 120 at least partially overlap in the first direction.

[0051] Specifically, the first extension portion 112 is provided on a side of the first pressing plate 111 facing the second pressing plate 121, and the second extension portion 122 is provided on a side of the second pressing plate 121 facing the first pressing plate 111. The first pressing block 110 and the second pressing block 120 at least partially overlap in the first direction, so that when the first pressing block 110 and the second pressing block 120 are relatively close to or away from each other, the distance between the end of the first extension portion 112 and the end of the second extension portion 122 in the first direction is adjustable. Therefore, when the distance between the end of the first extension portion 112 and the end of the second extension portion 122 in the first direction is small, the first extension portion 112 and the second extension portion 122 can be easily inserted into the side groove 410 of the frame 400; when the distance between the end of the first extension portion 112 and the end of the second extension portion 122 in the first direction is large, the first pressing block 110 and the second pressing block 120 can be engaged with the side groove 410 of the frame 400.

[0052] It should be noted that the end of the first extension portion 112 refers to the end of the first extension portion 112 away from the first pressing plate 111 , and the end of the second extension portion 122 refers to the end of the second extension portion 122 away from the second pressing plate 121 .

[0053] Among them, the other of the first pressing block 110 and the second pressing block 120 is partially inserted into the avoidance hole, so that the first pressing block 110 and the second pressing block 120 at least partially overlap in the first direction. This can limit the relative rotation of the first pressing block 110 and the second pressing block 120, so that the first pressing block 110 and the second pressing block 120 are aligned in the first direction. Therefore, when the first pressing block 110 and the second pressing block 120 are relatively close to or away from each other, the first extension portion 112 and the second extension portion 122 can simultaneously extend into the side groove 410 of the frame 400, thereby reducing the number of alignment steps on the first pressing block 110 and the second pressing block 120 and improving the efficiency of the frame 400 and the pressing block kit. Preferably, the first extension portion 112 and the second extension portion 122 both extend along the first direction.

[0054] In another embodiment, the first extension portion 112 and the second extension portion 122 are located on opposite sides of the first pressing plate 111 and the second pressing plate 121. Specifically, the fastener 200 is threadedly connected to the first pressing block 110 and the second pressing block 120. By controlling the fastener 200 to rotate about the first direction, the first pressing block 110 and the second pressing block 120 can move away from or closer to each other, thereby increasing or decreasing the distance between the end of the first extension portion 112 and the end of the second extension portion 122 in the first direction, thereby achieving the first pressing block 110 and the second pressing block 120 being engaged with or disengaged from the two first groove walls.

[0055] 1 , 2 , 4 and 5 , in one embodiment, a limiting wall 127 is provided on the second pressing block 120 . The limiting wall 127 is configured to abut against the first pressing plate 111 when the first pressing block 110 is pressed against the corresponding first groove wall, thereby limiting the first pressing plate 111 from approaching the second pressing plate 121 .

[0056] Specifically, when the first pressing block 110 is pressed against the lower groove wall 411 of the side groove 410 of the frame 400 and the frame 400 is pressed against the purlin 500, the limiting wall 127 can abut against the first pressing block 110, thereby limiting the first pressing block 110 and the second pressing block 120 from continuing to approach each other, thereby limiting the pressing force of the first extension portion 112 on the lower groove wall 411 from continuing to increase, preventing the lower groove wall 411 from deforming when the pressing force is too large, causing the installation groove 420 on the frame 400 to deform and affecting the installation of the photovoltaic module, thereby improving the reliability of the pressing block kit.

[0057] It should be noted that when the first pressing block 110 is pressed against the corresponding first groove wall, the second pressing plate 121 is restricted from moving away from the first pressing plate 111 , so that the limiting wall 127 can stably restrict the relative approach of the first pressing plate 111 and the second pressing plate 121 .

[0058] 1 , 3 , 4 , and 5 , in one embodiment, the second pressing block 120 further includes a connecting portion 124 , one end of the connecting portion 124 being connected to the second pressing plate 121 , and the other end being connected to the second extending portion 122 . The second pressing plate 121 is configured to abut against the purlin 500 , and the first extending portion 112 is configured to extend beyond the second extending portion 122 in a first direction.

[0059] Specifically, when the first pressing block 110 is pressed against the corresponding first groove wall, the second pressing plate 121 abuts against the purlin 500 , thereby limiting the distance between the second pressing plate 121 and the first pressing plate 111 , reducing the number of other components and simplifying the structure. Among them, the setting of the adapter portion 124 can enable the second extension portion 122 to be spaced from the second pressure plate 121 in a direction perpendicular to the second extension portion 122, and the first extension portion 112 to extend beyond the second extension portion 122 in the first direction, so that when the second pressure plate 121 abuts the purlin 500, it will not interfere with the second extension portion 122 extending into the side groove 410 of the frame 400, and will not interfere with the first extension portion 112 extending beyond the second extension portion 122 in the first direction, so that the distance between the end of the first extension portion 112 and the end of the second extension portion 122 in the first direction is adjustable, so that the first pressure block 110 and the second pressure block 120 are stably engaged with the side groove 410 of the frame 400, thereby improving the reliability of the pressure block kit.

[0060] Furthermore, an avoidance hole is provided on the adapter portion 124 , the first extension portion 112 is passed through the avoidance hole, and extends out of the second extension portion 122 in the first direction, so that the first extension portion 112 extends into the side groove 410 of the frame 400 and is crimped with the lower groove wall 411 .

[0061] Furthermore, the hole wall of the avoidance hole close to the second pressing plate 121 is configured as a limiting wall 127, and the limiting wall 127 is used to abut against the first pressing plate 111, thereby simplifying the structure of the pressing block assembly 100 and reducing the processing cost.

[0062] Referring to Figures 1 and 5, in one embodiment, the adapter portion 124 includes a first connecting segment 125 and a second connecting segment 126 connected to each other, the end of the first connecting segment 125 away from the second connecting segment 126 is connected to the first pressure plate 111, and the end of the second connecting segment 126 away from the first connecting segment 125 is connected to the second extension portion 122. The first connecting segment 125 and the second connecting segment 126 are arranged vertically, and the first connecting segment 125 extends along the first direction. The limiting wall 127 is arranged on the first connecting segment 125, thereby providing a supporting force to the first pressure plate 111 along the first direction, so that the first connecting segment 125 can stably abut against the first pressure plate 111.

[0063] Furthermore, the avoidance hole has an opening on the side away from the second pressure plate 121, and there are two second extension portions 122, which are spaced apart at both ends of the adapter portion 124, thereby facilitating the first pressure block 110 to extend into the avoidance hole, thereby facilitating the assembly of the pressure block kit and improving the adaptability of the pressure block kit.

[0064] Referring to Figures 1, 3, 4, 5, and 6, Figure 6 illustrates a schematic diagram of a pressure block assembly inserted into a side groove of a frame in a photovoltaic module mounting structure according to one embodiment of the present application. In one embodiment, in the second direction, the side of the first extension 112 distal to the fastener 200 is flush with the side of the second extension 122 distal to the fastener 200, wherein the second direction is perpendicular to the first direction.

[0065] Specifically, since the side of the first extension portion 112 away from the fastener 200 is flush with the side of the second extension portion 122 away from the fastener 200 in the second direction, when the second extension portion 122 extends into the side groove 410 of the frame 400, the first extension portion 112 must at least partially extend into the side groove 410 of the frame 400. Therefore, in the process of the first pressure plate 111 and the second pressure plate 121 approaching or moving away from each other, the second extension portion 122 can press the lower groove wall 411 while being hooked with the fourth section. That is, the pressure block assembly 100 only needs to be extended into the side groove 410 of the frame 400 relative to the thickness of the second extension portion 122 in the second direction to achieve the connection between the pressure block assembly 100 and the side groove 410 of the frame 400, thereby improving the efficiency of the hooking and matching between the pressure block kit and the side groove 410 of the frame 400. In addition, the requirement on the depth of the side groove 410 of the frame 400 can be reduced, so that the frame 400 with different side groove 410 depths can be adapted, thereby improving the adaptability of the pressing block kit.

[0066] Furthermore, in the second direction, the side of the first extension 112 proximal to the fastener 200 is flush with the same side of the second extension 122 proximal to the fastener 200. Thus, when the second extension 122 is hooked onto the fourth section, the first extension 112 can extend beyond the second section and stably abut against the first section. Furthermore, the depth requirement for the side groove 410 of the frame 400 is further reduced, thereby accommodating frames 400 having different side groove 410 depths and improving the adaptability of the pressure block kit.

[0067] Furthermore, the two second extensions 122 are spaced apart along a third direction that is perpendicular to both the first and second directions. Furthermore, the pressure block sets are symmetrically arranged on a plane perpendicular to the second direction, i.e., one pressure block set can simultaneously constrain the two frames 400 on the purlin 500.

[0068] Referring to Figures 1, 2, 3, and 7, Figure 7 illustrates a schematic diagram of a pressure block assembly inserted into a side groove of a frame in a photovoltaic module mounting structure according to one embodiment of the present application. In one embodiment, the pressure block assembly further comprises an elastic member 300 positioned between the first pressure block 110 and the second pressure block 120. The elastic member 300 is configured to apply a force to push the first pressure block 110 and the second pressure block 120 away from each other.

[0069] Specifically, the elastic member 300 is arranged between the first pressure plate 111 and the second pressure plate 121. The elastic member 300 is used to apply a thrust to the first pressure plate 111 and the second pressure plate 121 to move away from each other, so that when the second pressure plate 121 abuts against the purlin 500, the second pressure plate 121 can be pressed tightly against the purlin 500, limiting the second pressure block 120 from swinging in the first direction relative to the side groove 410 of the frame 400, so that the second extension portion 122 is stably hooked with the upper groove wall 412.

[0070] In addition, when the second pressing plate 121 abuts against the purlin 500, the distance between the first pressing plate 111 and the second pressing plate 121 in the first direction is maximized, thereby minimizing the spacing between the end of the first extension portion 112 and the end of the second extension portion 122 in the first direction. That is, without the need to additionally move the first pressing block 110 or the second pressing block 120, the first extension portion 112 and the second extension portion 122 can be conveniently inserted into the side groove 410 of the frame 400, thereby improving the efficiency of the pressing block kit being hooked with the side groove 410 of the frame 400. Specifically, by bringing the first pressing block 110 and the second pressing block 120 relatively close together, the spacing between the end of the first extension portion 112 and the end of the second extension portion 122 in the first direction can be increased, thereby enabling the pressing block kit to be hooked and engaged with the side groove 410 of the frame 400. Preferably, the elastic member 300 is sleeved on the fastener 200. Preferably, the elastic member 300 is a spring.

[0071] 1 , 2 , 3 , 6 , and 7 , in one embodiment, the fastener 200 includes a connecting rod 210 and a boss 230 . The boss 230 is disposed on the fastener 200 and is configured to abut against the first pressure block 110 . The connecting rod 210 is configured to rotate about a first direction to push the first pressure block 110 closer to the second pressure block 120 .

[0072] Specifically, the first pressing plate 111 is provided with a first mounting hole 113, and the second pressing plate 121 is provided with a second mounting hole 123. The fastener 200 is passed through the first mounting hole 113 and the second mounting hole 123 and connected to the purlin 500. When the connecting rod 210 rotates in the first direction, the connecting rod 210 can approach the purlin 500, and the boss 230 abuts the first pressing plate 111, thereby pushing the first pressing plate 111 toward the purlin 500, while the second pressing plate 121 abuts the purlin 500, so that the first pressing plate 111 and the second pressing plate 121 are relatively close to each other, thereby increasing the distance between the end of the first extension portion 112 and the end of the second extension portion 122 in the first direction, so that the first pressing block 110 and the second pressing block 120 are engaged with the side groove 410 of the frame 400.

[0073] Furthermore, a locking block 220 is provided on the connecting rod 210. The locking block 220 is connected to the side of the connecting rod 210 away from the boss 230 and is located on the side of the purlin 500 away from the pressure block assembly 100. The locking block 220 is used to be threadedly connected to the connecting rod 210 to fix the fastener 200 to the purlin 500. Preferably, the fastener 200 is a screw and the locking block 220 is a nut.

[0074] Referring to Figures 1, 3, 6 and 7, in one embodiment, the embodiment of the present application also includes a photovoltaic module mounting structure, including a frame 400 and the above-mentioned pressure block kit, the frame 400 is provided with a side groove 410, and a group of first groove walls of the side groove 410 opposite to each other along a first direction are engaged with the first pressure block 110 and the second pressure block 120. In the present application, the fastener 200 is connected to the purlin 500, and the first pressure block 110 and the second pressure block 120 are both sleeved on the fastener 200. By the first pressure block 110 and the second pressure block 120 approaching or moving away from each other in the first direction, the first pressure block 110 and the second pressure block 120 can be inserted into the side groove 410 of the frame 400 to engage with the two first groove walls, thereby limiting the frame 400 on the purlin 500 and limiting the pressure block assembly 100 from being dislodged from the side groove 410. That is, the pressure block kit in the present application does not need to be flipped or tilted to be plugged into the side groove 410 of the frame 400 to achieve the engaging engagement of the pressure block assembly 100 with the side groove 410 of the frame 400, so as to limit the frame 400 to the purlin 500, thereby improving the convenience and efficiency of installation.
