[0038] Figure 1 is a front view of a profile of an embodiment of the present application, Figure 2 Schematic diagram of a block assembly according to an embodiment of the present invention. Figure 1-2 As shown, the present application provides a pressing block assembly 10 , which is suitable for fixing two adjacent profiles 20 , wherein the profile 20 has a fixing plate 21 and a side groove 22 , and the pressing block assembly 10 includes an upper pressing block 100 and a lower pressing block 200 .

[0039] like Figure 2 FIG. 1 is a preferred embodiment of the present application. In this embodiment, the upper pressing block 100 and the lower pressing block 200 respectively have a first fastening hole 101 passing through (refer to FIG. 1 ). Figure 3 as shown) and the second fastening hole 201 (reference Figure 5 ), and the pressing block assembly 10 further includes a fastener 300 and a locking member 400, wherein the locking member 400 has a third fastening hole 401 extending therethrough, and the fastener 300 is adapted to pass through the first fastening hole 101, the second fastening hole 201, and the third fastening hole 301. Further, the locking member 400 also has a locking groove 402, and after installation, the locking groove 402 is adapted to be connected to the bracket 30 (not shown, refer to Figure 7-10 as shown) snap-on.

[0040] Figure 3 This is a three-dimensional schematic diagram of an upper pressing block according to an embodiment of the present application. Figure 4 This is a front view of the upper pressing block of an embodiment of the present application. Figure 1-4 As shown, the upper pressing block 100 includes a first fixing portion 110, a second fixing portion 120 and a fastening portion 130, wherein the first fixing portion 110 is located at a first side of the fastening portion 130 (eg, Figure 4 The second fixing portion 120 is located on the second side of the fastening portion 130 (as shown in the left side). Figure 4 The first fixing portion 110 and the second fixing portion 120 are respectively adapted to be connected to the adjacent two fixing portions. Figure 1 Specifically, the first fixing portion 110 and the second fixing portion 120 are respectively connected to the lower ends 23 of the side grooves 22 of the two adjacent profiles 20 .

[0041] Furthermore, in this embodiment, the upper pressing block 110 further includes a first groove 111 and a second groove 121, wherein the first groove 111 is located between the first fixing portion 110 and the fastening portion 130, and the second groove 121 is located between the second fixing portion 120 and the fastening portion 130. Fig.10 As shown, for ease of understanding, the two adjacent profiles 20 of the pressing block assembly 10 are named as the first profile 20a and the second profile 20b respectively. When the upper pressing block 100 is engaged with the first profile 20a and the second profile 20b, the lower end 23a of the side groove of the first profile 20a is suitable for being inserted into the first groove 111, and the lower end 23b of the side groove of the second profile 20b is suitable for being inserted into the second groove 121.

[0042] like Figure 1-4 The figure shows a preferred embodiment of the present application, in which a first vertical distance H1 is provided between the lower end 23 of the notch of the side groove 22 of the profile 20 and the lower surface of the profile 20, and a second vertical distance H2 is provided between the first groove 111, the second groove 121 and the lower surface of the fastening portion 130 of the upper pressing block 100 in the vertical direction, and H1>H2. Further, a third vertical distance H3 is provided between the lower surface of the first fixing portion 110 and the lower surface of the fastening portion 130 in the vertical direction, and a fourth vertical distance H4 is provided between the lower surface of the second fixing portion 120 and the lower surface of the fastening portion 130 in the vertical direction, and H2>H3>H4. This setting can enhance the fixing effect of the upper pressing block 100. After installation, the first groove 111 and the second groove 121 are suitable for clamping the lower end 23 of the notch of the profile 20, and the first fixing portion 110 and the second fixing portion 120 achieve a limiting effect on the profile 20 in the horizontal direction, so that it cannot slip off easily.

[0043] Figure 5 This is a three-dimensional schematic diagram of a lower pressing block according to an embodiment of the present application. Figure 6 This is a front view of the lower pressing block of an embodiment of the present application. Figure 1-2 5-6, the lower pressing block 200 includes a third fixing portion 210, a fourth fixing portion 220 and a bearing plate 230, and the third fixing portion 210 is located on a first side of the bearing plate 230 (such as Figure 6 The fourth fixing portion 220 is located on the second side of the supporting plate 230 (as shown in the left side). Figure 6 Specifically, the third fixing portion 210 has a convex strip 211, and the convex strip 211 is away from the edge of the supporting plate 230 (as shown in FIG. Figure 6The upper edge shown) has a flange 212 that protrudes from the upper edge of the rib 211 towards the fourth fixing portion 220, causing the third fixing portion 210 to form a hook-like shape similar to a "J", which is suitable for clamping the fixing plate 21 of the corresponding profile 20. After fixation, the rib 211 can restrict the movement of the profile 20 in the horizontal direction, while the flange 212 can, to a certain extent, restrict the movement of the profile 20 in the vertical direction.

[0044] Furthermore, the fourth fixing portion 220 has an upward flanging 221 and a clamping groove 222. The clamping groove 222 is located between the upward flanging 221 and the bearing plate 230 and is suitable for sliding into and connecting with the fixing plate 21 of the corresponding profile 20. It can be understood that the third fixing portion 210 and the fourth fixing portion 220 of the lower pressing block 200 are respectively suitable for fixing two adjacent profiles 20. Further referring to Fig.10 shown, the third fixing portion 210 is suitable for clamping the fixing plate 21a of the first profile 20a, and the clamping groove 222 of the fourth fixing portion 220 is suitable for sliding into and connecting with the fixing plate 22b of the second profile 20b.

[0045] As Figure 1-6 In a preferred embodiment of the present application, there is a first horizontal distance L1 between one end S1 of the notch of the side groove 22 of the profile 20, which is far from the fixing plate 21, and one end S2 of the fixing plate 21, which is far from the side groove 22 (refer to Figure 1 ), there is a second horizontal distance L2 between the two side surfaces of the fastening portion 130 of the upper pressing block 100 (refer to Figure 4 ), there is a third horizontal distance L3 between the two edges of the upper surface of the bearing plate 230 of the lower pressing block 200 (refer to Figure 6 ), the flange 212 has a protruding distance L4 relative to the rib 211 (refer to Figure 6 ), and 0 < L3 - 2 * L1 - L2 ≤ L4. Taking Figure 9-10 shown as an example, 2 * L1 + L2 is the distance between Sa2 and Sb2 after the first profile 20a, the second profile 20b, and the pressing block assembly 10 are combined together. Sa2 is one end of the fixing plate 21a of the first profile 20a, which is far from the side groove 22a, and Sb2 is one end of the fixing plate 21b of the second profile 20b, which is far from the side groove 22b.

[0046] It can be understood that, in order to ensure that the first profile 20a can be clamped into the third fixing portion 210 under the action of gravity, L3 needs to be greater than 2 * L1 + L2, that is, Sa2 and Sb2 will not simultaneously abut against the two edges of the upper surface of the bearing plate 230. Assuming that Sb2 has abutted against the edge of the upper surface of the bearing plate 230 (such as Fig.10 shown as the right edge, that is, the bottom of the clamping groove 222), then Sa2 and the other edge of the upper surface of the bearing plate 230 (such as Fig.10There is a gap between the left edge of the first profile 20a and the third fixing portion 210, and the width of the gap is equal to L3-2*L1-L2. However, if L3 is too large, the fixing effect of the lower pressing block 200 will be affected. Therefore, the width of this gap is smaller than the protruding distance L4 of the flange 212 relative to the convex strip 211, so that the fixing plate 21a of the first profile 20a will not be separated from the third fixing portion 210 in the vertical direction without external force.

[0047] The present invention also provides a method for installing the pressing block assembly 10 . Figure 7-10 Schematic diagram of the matching process of the pressing block assembly and the profile according to an embodiment of the present application. Figure 3-10 As shown, the assembly process of the pressing block assembly 10 and the profiles 20a, 20b is described in detail as follows:

[0048] (1)Reference Figure 1-7 As shown, firstly, the second profile 20b with the photovoltaic laminate 40 and the block assembly 10 are placed on the bracket 30. It should be noted that the lower block 200 needs to be placed between the second profile 20b and the bracket 30, and the fixing plate 21b of the second profile 20b is located on the bearing plate 230. At this time, the upper block 100 is suspended, the second groove 121 of the upper block 100 is aligned with the lower end 23b of the side groove notch of the second profile 20b, and the fastener 300 (not shown) is not installed temporarily.

[0049] (2)Reference Figure 1-6 8, the lower pressing block 200 is translated along the bracket 30 in the direction away from the second profile 20b until the fixing plate 21b of the second profile 20b slides into the clamping groove 222, and then the upper pressing block 100 is placed downward until the lower end 23b of the notch of the second profile 20b is inserted into the second groove 121 of the upper pressing block 100. At this time, the first fastening hole 101 of the upper pressing block 100 and the second fastening hole 201 of the lower pressing block 200 are opposite, and the fastener 300 is installed so that it passes through the first fastening hole 101, the second fastening hole 201 and the locking member 400 in sequence (not shown, refer to Figure 2 As shown) and tighten, thereby fixing the second profile 20b on the bracket 30.

[0050] (3)Reference Figure 1-6 As shown in Figure 9, the first profile 20a installed with the photovoltaic laminate 40 is placed on the lower pressing block 200 at an angle so that the lower end 23a of the side groove is inserted between the first fixing portion 110 of the upper pressing block 100 and the supporting plate 230 of the lower pressing block 200. At this time, the fixing plate 21a of the first profile 20a is overlapped on the flange 212 of the lower pressing block 200.

[0051] (4)Reference Figure 1-6As shown in Figure 10, the first profile 20a is laid flat. Under the weight of the photovoltaic laminate 40 and the first profile 20a, the fixing plate 21a of the first profile 20a is inserted under the flange 212, and the lower end 23a of the notch of the side groove 22a is inserted into the first groove 111 of the upper pressing block 100, and the installation is completed. It should be noted that the protruding distance L4 of the flange 212 relative to the convex strip 211 needs to be less than a threshold value, which is the maximum protrusion degree of the flange 212. When the flange 212 is less than the threshold value, the first profile 20a is naturally laid flat to allow the fixing plate 21a to be inserted under the flange 212.

[0052] Specifically, after the second profile 20b on one side of the pressing block assembly 10 is installed, the staff can directly tighten the fastener 300 and then continue to install the first profile 20a on the other side without operating the pressing block assembly 10 that has been set between two adjacent profiles 20, thereby reducing the difficulty of operation and avoiding the risk of irregular operations such as the staff kneeling to press the photovoltaic components.

[0053] In addition, if Fig.10 After the first profile 20a, the second profile 20b and the block assembly 100 are installed, the next step is to continue to install another block assembly 10 on the other side of the first photovoltaic module 50a installed with the first profile 20a. The installation method can also refer to Figure 7 As shown: It can be understood that the position of the first photovoltaic component 50a is fixed and cannot be moved, so the pressing block assembly 10 can only be translated. Specifically, lift the unfixed end of the first photovoltaic component 50a to leave a gap between the first profile 20a and the bracket 30 to allow another lower pressing block 200 to slide in. The following steps can refer to the above (1) to (4).

[0054] refer to Figure 7-10 As shown, the disassembly process also does not require the operation of the block assembly 10 that has been set between two adjacent profiles 20: first, lift the first profile 20a upward, and its fixing plate 21a will be separated from the third fastening part 210. At this time, the staff can directly disassemble the block assembly 10. After the fastener 300 is unscrewed, the upper block 100 can be directly taken out, and the lower block 200 needs to be translated along the bracket 30 toward the direction of the second profile 20b until the fixing plate 21b slides out of the clamping groove 222 (refer to Figure 6 As shown), the second profile 20b can be lifted to remove the lower pressing block 200.

[0055] Further, combined with reference Figure 1-6As shown in FIG. 10 , the upper surface of the upper pressing block 100 in the pressing block assembly 10 provided by the present invention is lower than the upper surfaces of the two adjacent profiles 20 and is completely located in the installation gap between the two adjacent profiles 20. After installation, it will not protrude from the photovoltaic module, ensuring the aesthetics. In addition, the upper pressing block 100 only fixes the side groove 22 of the profile 20, that is, the force-bearing surface is the B surface of the profile 20 (i.e., Figure 1 The left side shown). In the prior art, the pressing block is often pressed against the A surface (i.e., the upper surface) of the profile. This fixing method relies on the friction between the pressing block and the A surface of the profile, and the fixing effect is poor. In order to ensure the fixing strength, the pressing block is often required to have a large pressing force on the profile, but this may cause the upper surface of the photovoltaic laminate to be cracked. The upper pressing block 100 of the present invention is pressed against the bottom of the side groove 22 of the profile 20, which can increase the pressing force to ensure that the profile 20 does not move laterally while avoiding damage to the photovoltaic laminate, thereby enhancing the service life.

[0056] Furthermore, in a pressing block assembly 10 provided by the present invention, the fixing plate 21 (i.e., the extended C surface) of the profile 20 is fixed by the lower pressing block 200, which further enhances the fixing effect compared with the method of fixing only the B surface, and reduces the requirement for the thickness of the extended C surface compared with the method of fixing only the C surface. Specifically, if only the B surface of the profile is fixed, under severe weather conditions such as strong winds, the photovoltaic component may be lifted, resulting in the separation between the profile and the pressing block, causing economic losses. When only the extended C surface is fixed, the C surface needs to have a certain thickness and strength to avoid damage to the profile, and the fixing effect is not good. In the present invention, the lower pressing block 200 further fixes the C surface of the pressing block 20, and adopts an asymmetric design. While the fourth fixing portion 220 limits the profile 20 in the vertical direction through the clamping groove 222, the third fixing portion 210 is provided with a convex strip 211 and a flange 212, which solves the problem of difficult installation and disassembly.

[0057] Fig.11 is a three-dimensional schematic diagram of a pressing block assembly according to another embodiment of the present application. Fig.12 2 is a three-dimensional schematic diagram of a lower pressing block according to another embodiment of the present application.
