[0009] Among them, the two top components are provided with a limiting protrusion at one end facing each other. The limiting protrusion is located on the side of the top component away from the bottom wall. The limiting protrusion protrudes upward and is used to engage with the limiting protrusion on the frame for positioning.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0050] See Figures 1-5An embodiment of this utility model provides a pressure block 100, which is used to install between two adjacent photovoltaic modules 200. The pressure block 100 includes two opposing side walls 101, a bottom wall 102 and a reinforcing rib 120 arranged at an angle to the side walls 101. The two side walls 101 are arranged along a first direction X, and the two side walls 101 and the bottom wall 102 form a groove 111. The reinforcing rib 120 is disposed in the groove 111, and the two ends of the reinforcing rib 120 are respectively connected to the side wall 101 and / or the bottom wall 102. The first direction X is the arrangement direction of the two photovoltaic modules 200.

[0051] This technical solution discloses a pressure block 100, which is used to connect the frame 300 of the photovoltaic module 200 to the mounting bracket. The two ends of the pressure block along a first direction are used to engage with the frame 300, and the bottom wall of the pressure block is used to fix it to the mounting bracket. A groove 111 is formed by the two side walls and the bottom wall. This reduces the weight and material usage of the pressure block 100, thereby lowering production costs. It also provides elastic deformation space for the installation of the pressure block 100 and the frame 300. Reinforcing ribs 120 are provided within the groove 111, and the two ends of the reinforcing ribs 120 are respectively connected to the side wall or the bottom wall of the groove 111, thereby increasing the tensile strength of the side wall of the pressure block with less material. This structure improves the tensile strength and deformation resistance of the pressure block 100, ensuring that when the pressure block 100 is installed into the mounting groove on the frame 300, the side wall of the pressure block does not deform excessively, preventing the space of the mounting groove from being insufficient to meet the deformation requirements of the pressure block 100.

[0052] The two side walls and the bottom wall together form a U-shaped structure, and the U-shaped structure, which is the entire length of the side walls and the bottom wall, extends along a straight line. The number of reinforcing ribs 120 can be one, two, or even more. The extending direction of the reinforcing ribs 120 is consistent with the extending direction of the U-shaped structure. The two ends of the reinforcing rib 120 in the width direction can be connected to the two side walls respectively, or one end can be connected to a side wall and the other end to the bottom wall.

[0053] like Figures 1 to 5 As shown, in one embodiment, each of the two sidewalls 101 is provided with a top member 130 that can move up and down. The two top members 130 are located at the opening of the groove 111 and face the groove 111. Each of the two top members 130 has a limiting protrusion 131 at one end facing each other. The limiting protrusion 131 is located on the side of the top member 130 away from the bottom wall and protrudes upwards. The limiting protrusion 131 is used to engage with and limit the positioning of the limiting protrusion 310 on the frame 300.

[0054] By setting the top component 130 in the groove of the groove 111 and connecting one end of the two top components 130 to the side wall of the groove 111 respectively, with the two top components 130 facing the groove 111, the top components 130 can move up and down along the groove depth of the groove 111. This allows the top components 130 to adapt to the groove width of the mounting groove of the frame 300 when connecting the pressure block 100 to the frame 300 on the photovoltaic module 200, thereby allowing the pressure block 100 to be pushed into the mounting groove of the frame 300 along the first reverse direction with a smaller force. By providing limiting protrusions 131 on one end of the top member 130 facing each other, when the pressure block 100 is installed into the mounting groove on the frame 300, the up and down movement of the top member 130 allows the size of the pressure block 100 along the groove depth direction of the groove 111 to adapt to the groove width of the mounting groove of the frame 300, thereby allowing the pressure block 100 to be installed into the mounting groove of the frame 300 at both ends along the groove width direction of the groove 111.

[0055] Understandably, since the top component 130 of the pressure block 100 is located at the opening of the groove 111, if the top component 130 is to be installed into the mounting groove of the frame 300, the corresponding part of the bottom wall 102 and the top component 130 also need to be installed into the mounting groove. That is, the ends of the pressure block 100 along the first direction are all installed into the mounting groove of the frame 300. With this structure, the mounting groove of the frame 300 needs to have a large space to provide sufficient space for the deformation of the top component 130, and the ends of the pressure block 100 need to be installed into the mounting groove.

[0056] In this embodiment, the limiting protrusion 131 is provided at the end of the top component 130 away from the side wall, so as to increase the contact area between the pressure block 100 and the groove wall of the mounting groove of the frame 300, thereby ensuring the reliability of the connection between the pressure block 100 and the frame 300. In addition, the distance between adjacent photovoltaic modules 200 can be reduced, thereby increasing the installation area of ​​photovoltaic modules 200 per unit area.

[0057] like Figure 1 As shown, in one embodiment, limiting protrusions 131 extend from the opposing ends of the two top components 130. By extending the limiting protrusions 131 from the opposing ends of the top components 130 towards each other, the ends of the top components 130 can protrude beyond the ends of the frame 300 after the pressure block 100 is connected to the frame 300. This facilitates the use of tools to press against the ends of the top components 130 when it is necessary to disassemble the photovoltaic module 200, causing the top components 130 to elastically deform, thereby facilitating the separation of the limiting protrusions 131 from the limiting latches 310 on the frame 300. In other words, the above structure facilitates the disassembly of the photovoltaic module 200.

[0058] like Figure 1 As shown, in one embodiment, there is one reinforcing rib 120, and the two ends of the reinforcing rib 120 are respectively connected to the two side walls of the groove 111. The reinforcing rib 120 is spaced apart from the bottom wall 102.

[0059] By connecting the two ends of the reinforcing rib 120 to the two side walls of the groove 111 respectively, the tensile strength between the two side walls of the groove 111 on the pressure block is improved, thereby preventing irreversible deformation of the pressure block 100 caused by excessive load on the photovoltaic module 200. Specifically, for example, when the left and right ends of the pressure block 100 are respectively connected to the mounting grooves of the frames 300 of two adjacent photovoltaic modules 200, when the photovoltaic module 200 is subjected to a load from top to bottom, the photovoltaic module 200 generates torque on the pressure block 100. If the two side walls are connected by the reinforcing rib 120, irreversible deformation of the pressure block 100 can be prevented when the photovoltaic module 200 applies torque to the pressure block 100.

[0060] The reinforcing ribs 120 are spaced apart from the bottom wall 102, ensuring the structural strength of the pressure block 100 while reducing its weight. In this embodiment, the reinforcing ribs 120 are located between the top component 130 and the bottom wall along the depth direction of the groove 111. It is understood that the side wall 101, bottom wall 102, top component 130, and reinforcing ribs 120 are integrally formed from aluminum alloy through extrusion. The extending direction of the reinforcing ribs 120 is the same as that of the side wall 101 and the top component 130. In other words, the reinforcing ribs 120 are plate-like structures, with their length direction aligned with the length directions of the side wall 101 and bottom wall 102, and their width ends connected to two oppositely arranged side walls.

[0061] like Figure 2 As shown, in one embodiment, the reinforcing rib 120 includes a first reinforcing rib 121. Two first reinforcing ribs 121 are spaced apart along the width direction of the groove 111. One end of each first reinforcing rib 121 is connected to the two side walls of the groove 111, and the other end is connected to the bottom wall. The two first reinforcing ribs 121 form two spaced cavities with the bottom wall and the two side walls respectively.

[0062] By arranging two first reinforcing ribs 121 at intervals along a first direction, with one end of each rib connected to the sidewall of the groove 111 and the other end connected to the bottom wall, the two sidewalls, the two first reinforcing ribs 121, and the bottom wall respectively enclose cavities spaced apart along the first direction, thereby improving the tensile strength between the two sidewalls and the bottom wall. With this arrangement, when two adjacent photovoltaic modules 200 are connected to the mounting bracket via the pressure block 100, the photovoltaic modules 200 apply torque to the pressure block 100. Since the two first reinforcing ribs 121 respectively apply tensile force to the sidewalls, irreversible deformation of the pressure block 100 can be prevented. It is understood that in this embodiment, the extending direction of the first reinforcing ribs 121 is consistent with the extending direction of the pressure block.

[0063] like Figure 3 and Figure 4 As shown, in one embodiment, each first reinforcing rib 121 includes an arc-shaped segment 1211 and a straight segment 1212 connected to each other. One end of the arc-shaped segment 1211 is fixedly connected to the side wall; a section of the straight segment 1212 opposite to the arc-shaped segment 1211 extends to the bottom wall and is fixedly connected to the bottom wall.

[0064] It should be noted that, in this embodiment, the arc-shaped segment 1211 and the straight segment 1212 of the first reinforcing rib 121 are viewed from the cross-sectional perspective of the pressure block 100. Throughout the entire extending direction of the pressure block 100, the arc-shaped segment 1211 and the straight segment 1212 of the first reinforcing rib 121 extend along the extending direction of the pressure block 100.

[0065] By setting the first reinforcing rib 121 in the form of a combination of an arc-shaped segment 1211 and a straight segment 1212, with one end of the arc-shaped segment 1211 fixedly connected to a sidewall and the other end extending towards the other sidewall and then downward, the torsional and tensile properties of the sidewall can be improved. The portion connecting to the bottom wall and the arc-shaped segment 1211 is set as a straight segment 1212, so that while ensuring the torsional and tensile properties of the pressure block 100, space within the groove 111 can be saved, thus providing the pressure block with first reinforcing ribs 121 at both ends along the first direction.

[0066] like Figure 3 and Figure 4As shown, in one embodiment, the reinforcing rib 120 further includes a second reinforcing rib 122, with both ends of the second reinforcing rib 122 connected to the two first reinforcing ribs 121, and the second reinforcing rib 122 spaced apart from the bottom wall. By connecting the second reinforcing rib 122 between the two first reinforcing ribs 121 and setting the second reinforcing rib 122 to be spaced apart from the bottom wall, the second reinforcing rib 122 is closer to the groove opening, thereby applying a tensile force to the first reinforcing ribs 121 through the second reinforcing rib 122. When the photovoltaic module 200 applies torque to the pressure block 100, since the second reinforcing rib 122 applies a tensile force to the two first reinforcing ribs 121, and the two first reinforcing ribs 121 respectively apply a tensile force to the sidewall, irreversible deformation of the pressure block 100 can be prevented.

[0067] like Figure 5 As shown, in another embodiment, the reinforcing rib 120 includes two first ribs 123 and second ribs 124. One end of each first rib 123 is fixedly connected to the bottom wall, and the other end extends away from the bottom wall. Both ends of the second rib 124 are fixedly connected to the ends of the first ribs 123 away from the bottom wall, respectively. The first ribs 123, second ribs 124, and bottom wall together form a cavity. This structural form strengthens the bottom wall 102, thereby improving the overall structural strength of the pressure block 100.

[0068] like Figures 1 to 5 As shown, in one embodiment, a first support rib 113 and a second support rib 114 are provided on the side of the bottom wall 102 opposite to the groove, and the first support rib and the second support rib are spaced apart along a first direction; wherein the first support rib 113 and the second support rib 114 have different heights.

[0069] By constructing a first support rib 113 and a second support rib 114 on the bottom wall 102, and setting the heights of the first support rib 113 and the second support rib 114 to different forms, when assembling two adjacent photovoltaic modules 200 together, the end of the pressure block 100 corresponding to the support rib with a lower height can press tightly against the frame 300 of the corresponding photovoltaic module 200, thereby making the connection between the frame 300 of the photovoltaic module 200 and the corresponding pressure block 100 end more firm and reliable; for the end of the pressure block 100 corresponding to the support rib with a higher height, due to the relatively higher height of the support rib, the space between the bottom surface of the pressure block 100 at the corresponding end and the mounting bracket is larger, thereby making it easier to insert the bottom of the frame 300 when engaging the frame 300 on another photovoltaic module 200 with the corresponding pressure block 100. This ensures the reliability of the connection between the frame 300 and the pressure block 100 on one side, while making the installation of the frame 300 and the pressure block 100 on the other side easier.

[0070] In this embodiment, the height of the first support rib 113 can be set lower than that of the second support rib 114, or the height of the second support rib 114 can be set lower than that of the first support rib 113. However, regardless of which support rib is lower, during installation, the pressure block 100 at the end corresponding to the support rib with the lower height and the corresponding side frame 300 are installed first; then the pressure block 100 at the end corresponding to the support rib with the higher height and the corresponding side frame 300 are installed.

[0071] For example, with Figure 1 For example, the first support rib 113 is set to be lower than the second support rib 114. In this case, when installing the photovoltaic module 200, first connect the frame 300 on the left side of the photovoltaic module 200 to the pressure block 100, and then fix the pressure block 100 to the mounting bracket using fasteners such as bolts 400. Because the first support rib 113 is lower, the left end of the pressure block 100 can press the bottom of the frame 300 on the left side of the photovoltaic module 200 onto the mounting bracket, thereby making the connection between the frame 300 of the photovoltaic module 200 and the pressure block 100 more secure. Finally, align the mounting groove of the frame 300 on the right side of the photovoltaic module 200 with the right end of the pressure block 100, and push the photovoltaic module 200 towards the pressure block 100 so that the corresponding frame 300 engages with the pressure block 100. Understandably, because the second support rib 114 is relatively high, the space between the bottom right end of the pressure block and the mounting bracket is relatively large, which makes it easier for the bottom of the frame 300 to be inserted between the bottom wall 102 and the mounting bracket.

[0072] like Figure 4 As shown, in one embodiment, along the width direction of the groove 111 and in the first direction, a plurality of spaced-apart protrusions are provided at both ends of the bottom wall 102. By providing a plurality of spaced-apart protrusions 112 at both ends of the bottom wall, after the pressure block 100 is connected to the frame 300, the protrusions 112 at the bottom of the pressure block engage with the recesses 320 on the frame 300, thereby preventing the pressure block 100 from sliding out of the mounting groove of the frame 300. The engagement of the protrusions 112 on the bottom surface of the pressure block 100 with the recesses 320 of the frame 300 prevents the pressure block 100 from falling off under reverse pressure, thereby ensuring the reliability of the photovoltaic module 200 under high load.

[0073] The bottom wall 102 includes abutment areas 1021, which are located at both ends of the bottom of the bottom wall 102 along a first direction. The abutment areas 1021 are used to abut against the frame 300 of the photovoltaic module 200. Each abutment area 1021 is inclined upward at one end toward the side wall. By setting the abutment areas to be inclined upward at one end toward the side wall, the abutment areas are parallel to the connecting surface of the frame 300, which makes it easier to push the pressure block 100.

[0074] like Figures 6 to 8 As shown, an embodiment of the present invention also provides a photovoltaic system 1000. The photovoltaic system 1000 includes a pressure block 100, a photovoltaic module 200, and a frame 300. The frame 300 is fixedly connected to the edge of the backlight surface of the photovoltaic module 200, and a mounting groove is constructed on the frame 300. The opposite ends of the pressure block 100 are respectively engaged in the mounting grooves of the frames 300 corresponding to two adjacent photovoltaic modules 200, and the frame 300 is fixedly connected to the mounting bracket.

[0075] By applying the above-mentioned pressure block 100 to the photovoltaic system 1000, and by setting the reinforcing rib 120 on the pressure block 100, after the frame 300 corresponding to the photovoltaic module 200 is connected to the pressure block 100, when the photovoltaic module 200 is subjected to high load, the reinforcing rib 120 improves the tensile strength of the pressure block 100, thereby preventing the pressure block 100 from opening outward.

[0076] refer to Figures 6 to 8 It is understood that the installation method of the pressure block 100 and the frame 300 on the photovoltaic module 200 provided in this embodiment of the present invention is as follows:

[0077] First, install the left-side photovoltaic module 200. Place the left-side photovoltaic module 200 flat on the mounting bracket or purlin. Align the left end of the pressure block 100 with the mounting groove of the frame 300 on the left-side photovoltaic module 200, and push it horizontally towards the frame 300 until the pressure block 100 engages with the mounting groove of the frame 300 on the photovoltaic module 200. During installation, when the pressure block 100 begins to push into the mounting groove of the frame 300, the limiting protrusion 131 on the pressure block 100 contacts the limiting locking protrusion 310 on the frame 300, causing the top part 130 of the pressure block 100 to bend under force. After the pressure block 100 has pushed a certain distance, the limiting protrusion 131 on the top part 130 of the pressure block 100 passes over the limiting locking protrusion 310 on the frame 300, and the two mutually resist and limit each other. The bottom surface of the pressure block 100 is designed as a slope, parallel to the connecting surface of the frame 300, which facilitates the advancement of the pressure block 100. After the pressure block 100 is pushed into place, the protruding structure 112 of the pressure block 100 and the recessed structure 320 of the frame 300 engage with each other.

[0078] Then, the pressure block 100 is locked onto the mounting bracket with bolts 400. Finally, the right photovoltaic module 200 is installed. The photovoltaic module 200 is placed flat on the mounting bracket so that the wide edges of the left and right photovoltaic modules 200 are aligned. The photovoltaic module 200 is pushed in along the first direction towards the pressure block 100. When the pressure block 100 begins to push into the mounting groove of the frame 300, the limiting protrusion 131 on the pressure block 100 contacts the limiting locking protrusion 310 on the frame 300. The top part 130 of the pressure block 100 bends under force. After the pressure block 100 has been pushed a certain distance, the limiting protrusion 131 on the top part 130 of the pressure block 100 passes over the limiting locking protrusion 310 on the frame 300. The two resist each other and limit the movement, thus completing the installation.
