Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module installation technology, and in particular to a quick-release clamping device for photovoltaic modules. Background Technology

[0002] Currently, photovoltaic panel clamping devices used in photovoltaic modules mostly employ a fixing assembly that uses wing nuts (such as plastic clips or nylon materials) in conjunction with bolts. The structure includes an aluminum alloy clamping block body with holes at both ends, which are locked to the bracket guide rail by the wing nuts. The wing nuts of this fixing assembly are prone to damage; frequent disassembly and assembly lead to thread wear and breakage, resulting in high maintenance costs. Furthermore, high installation precision is required, as the nuts must be precisely inserted into the guide rail grooves, making the operation time-consuming. Utility Model Content

[0035] Reference Figures 1 to 4 The quick-release clamping device for photovoltaic modules proposed in this embodiment includes a clamping assembly 100, a connecting plate 200, a connecting shaft 300, and a snap-fit ​​quick-release structure 400. The clamping assembly 100 includes a first clamping block 110 and a second clamping block 120 arranged opposite to each other, thereby forming an installation space 150 between the first clamping block 110 and the second clamping block 120. The installation space 150 is used for inserting the photovoltaic panel of the photovoltaic module, so that one side of the photovoltaic panel is accommodated in the installation space 150. The first clamping block 110 is provided with a first through hole 111, which penetrates the first clamping block 110 along the thickness direction. The second clamping block 120 is provided with a second through hole 121, which penetrates the second clamping block 120 along the thickness direction. The first through hole 111 and the second through hole 121 are coaxial.

[0036] The connecting plate 200 is located on the side of the second pressure block 120 away from the first pressure block 110. The connecting plate 200 is used to connect with the bracket 500 of the photovoltaic module. The connecting plate 200 is provided with a third through hole 210 and a mounting member 220. The mounting member 220 is provided with a receiving cavity 221. In this embodiment, the mounting member 220 is located on the side of the connecting plate 200 away from the second pressure block 120, and the receiving cavity 221 communicates with the third through hole 210.

[0037] The connecting shaft 300 passes through the first through hole 111 and the second through hole 121, and the connecting shaft 300 can move along its own axial direction. (Refer to...) Figure 4 When the connecting shaft 300 moves downward along its own axial direction, the connecting shaft 300 can pass through the receiving cavity 221; see reference. Figure 8 When the connecting shaft 300 moves upward along its own axis, the connecting shaft 300 can disengage from the receiving cavity 221.

[0038] The snap-on quick-release structure 400 includes a snap-on clip 410 and a clip slot 420, see reference. Figure 6 In this embodiment, two buckles 410 are provided, and the two buckles 410 are arranged opposite each other on both sides of the mounting member 220. Specifically, the mounting member 220 is provided with a mounting cavity 222, one end of which has a boss 223. The buckle 410 has a connecting rod 411 and a locking block 412. The buckle 410 is disposed in the mounting cavity 222. A second elastic member 413 is sleeved on the connecting rod 411. One end of the second elastic member 413 abuts against the boss 223, and the other end abuts against the locking block 412. The buckle 410 can move axially along the mounting cavity 222 within the mounting cavity 222, and the locking block 412 can extend into the receiving cavity 221. A limiting member 320 is provided at the end of the connecting shaft 300 near the second pressing block 120. The diameter of the limiting member 320 is larger than the diameter of the connecting shaft 300 at the connection point with the limiting member 320. The connecting shaft 300 is provided with a movable member 330, which can move along the axial direction of the connecting shaft 300. A first elastic member 310 is sleeved on the connecting shaft 300. One end of the first elastic member 310 is connected to the movable member 330, and the other end abuts against the second pressure block 120. The movable member 330 and the limiting member 320 can form the aforementioned groove 420. The groove 420 is annular. When the connecting shaft 300 passes through the receiving cavity 221, the locking block 412 of the buckle 410 can be inserted into the groove 420. A retraction structure is provided between the movable member 330 and the buckle 410. During the process of the connecting shaft 300 exiting the receiving cavity 221, the retraction structure is used to drive the locking block 412 of the buckle 410 to exit the groove 420, so that the connecting shaft 300 can be disengaged from the receiving cavity 221.

[0039] Reference Figure 6When assembling photovoltaic modules using the pressing device, the connecting plate 200 is fixed on the photovoltaic module bracket 500. An annular groove 420 is formed between the movable part 330 and the limiting part 320. The first pressing block 110 and the second pressing block 120, which are equipped with the connecting shaft 300, are placed on the photovoltaic module bracket 500. One end of the connecting shaft 300 is aligned with the third through hole 210 on the connecting plate 200. The connecting shaft 300 is pressed downwards, causing it to move downwards along its own axis. Insert the 00 into the third through hole 210 and extend it into the receiving cavity 221. At the same time, the limiting member 320 presses against the buckle 410, causing the buckle 410 to retract into the mounting cavity 222. The second elastic member 413 is compressed, and the connecting shaft 300 continues to move downward. The connecting shaft 300 continues to descend into the receiving cavity 221. The buckle 410 disengages from the pressing of the limiting member 320 and resets under the action of the second elastic member 413. The buckle 410 is then engaged in the slot 420, thus completing the assembly of the pressing block device.

[0040] Figure 7 , Figure 8 When disassembling the pressure block device, press down on the connecting shaft 300. The connecting shaft 300 moves downward along its own axis. The latch 410 exits the slot 420 under the pressure of the movable part 330 and abuts against the retraction structure of the movable part 330. The first elastic element 310 stretches. At this time, lift the pressure block assembly 100 upward. The connecting shaft 300 moves upward along the axis of the receiving cavity 221. Under the action of the retraction structure, the latch 410 drives the movable part 330 downward until the lower end face of the movable part 330 fits against the lower end face of the limiting element 320. The slot 420 disappears. Continue to lift upward. As the pressing block assembly 100 moves upward, the movable part 330 and the limiting part 320 move upward. The latch 410 is retracted by the top pressure of the retraction structure and the second elastic element 413 is compressed. When the movable part 330 moves upward and disengages from the latch 410, the latch 410 is reset to below the upper end face of the limiting part 320 under the action of the second elastic element 413. At the same time, the movable part 330 is reset under the action of the first elastic element 310. At this time, the latch 410 is released from the constraint of the slot 420, and the connecting shaft 300 can be released from the receiving cavity 221, thereby completing the disassembly of the pressing block device.

[0041] In summary, this utility model adopts a snap-fit ​​quick-release structure 400 set on the connecting plate 200 and the connecting shaft 300, which abandons the traditional threaded and nut connection structure, reduces the number of vulnerable parts, lowers maintenance costs, and enables the quick installation and disassembly of the pressing device, reducing the difficulty of disassembly and assembly and improving the efficiency of disassembly and assembly.

[0042] It should be noted that the first elastic element 310 and the second elastic element 413 can both be spring structures or other structures that can be compressed axially, and no limitation is made here.

[0043] It should be noted that the buckle 410 can be set as one or more, and when the gap between the connecting plate 200 and the second pressure block 120 is large enough, the mounting part 220 can also be set on the side of the connecting plate 200 facing the second pressure block 120, thereby eliminating the need for machining the third through hole 210, which will not be described in detail here.

[0044] Understandably, referring to Figure 4 The diameter of the connecting shaft 300 near the limiting member 320 is smaller than the diameter of other parts of the connecting shaft 300. As a result, the size of the mounting member 220, the limiting member 320, and the moving member 330 can be reduced, as can the size of the third through hole 210 and the receiving cavity 221, thereby reducing the processing difficulty and reducing material consumption.

[0045] Reference Figure 4 , Figure 6 , Figure 7 , Figure 8 The limiting member 320 is provided with a guide surface 322, which facilitates the insertion of the connecting shaft 300 into the third through hole 210 and the receiving cavity 221.

[0046] Reference Figures 1 to 4 The connecting plate 200 has blocking portions 230 on both sides. In this embodiment, the blocking portions 230 are formed by bending the side of the connecting plate 200 upward. The blocking portions 230 cooperate with the components on the bracket 500 to facilitate the assembly and positioning of the connecting plate 200.

[0047] Reference Figures 1 to 4 In some embodiments, a locking knob 340 is rotatably provided at one end of the connecting shaft 300 near the first pressure block 110. Rotating the locking knob 340 upwards can drive the connecting shaft 300 to move downwards along its axial direction. The latch 410 is disengaged from the slot 420 under the pressure of the movable member 330 and abuts against the retraction structure of the movable member 330. The first elastic member 310 is stretched. At this time, the pressure block assembly 100 is lifted upwards, and the connecting shaft 300 moves upwards along the axial direction of the receiving cavity 221. Under the action of the retraction structure, the latch 410 drives the movable member 330 downwards. When the lower end face of the movable part 330 is aligned with the lower end face of the limiting part 320, the slot 420 disappears. As the pressure block assembly 100 continues to rise, the movable part 330 and the limiting part 320 move upwards with the pressure block assembly 100. The latch 410 retracts under the pressure of the retraction structure, and the second elastic element 413 is compressed. When the movable part 330 moves upwards and disengages from the latch 410, the latch 410 resets to below the upper end face of the limiting part 320 under the action of the second elastic element 413. Simultaneously, the movable part 330 resets under the action of the first elastic element 310. Furthermore, when the pressure block device is in the assembled state, rotating the locking knob 340 to be flush with the first pressure block 110 will keep the latch 410 and the slot 420 in a engaged state.

[0048] Reference Figure 6 , Figure 7 , Figure 8 In some embodiments, the retraction structure includes a first mating surface 414 provided on the buckle 410 and a second mating surface 331 provided on the movable member 330. The first mating surface 414 is provided on the side of the buckle 410 near the movable member 330, and the horizontal height of the first mating surface 414 gradually decreases along the direction from the side wall of the receiving cavity 221 to the axis of the receiving cavity 221. The second mating surface 331 is located on the side wall of the movable member 330. Along the direction from the movable member 330 to the second pressure block 120, the distance from the second mating surface 331 to the axis of the connecting shaft 300 gradually decreases. When the connecting shaft 300 is pressed down, it moves downwards along its own axis. The movable member 330 follows the downward movement of the connecting shaft 300. The movable member 330 acts on the first mating surface 414 of the latch 410, causing the latch 410 to retract and exit the slot 420. The connecting shaft 300 continues to move downwards, and the latch 410 abuts against the second mating surface 331 of the movable member 330. At this time, the pressure block assembly 100 is lifted upwards, and the connecting shaft 300 moves upwards along the axis of the receiving cavity 221. During the upward movement of the connecting shaft 300, the latch 410... The movable part 330 is moved downward until its lower end face aligns with the lower end face of the limiting part 320, the slot 420 disappears, and the first elastic element 310 is in a stretched state. The pressing block assembly 100 is then lifted upward, and the movable part 330 and the limiting part 320 move upward with the pressing block assembly 100. The latch 410 is retracted by the pressure of the second mating surface 331, and the second elastic element 413 is compressed. When the movable part 330 moves upward until it disengages from the latch 410, the latch 410 resets to below the upper end face of the limiting part 320 under the action of the second elastic element 413. At the same time, the movable part 330 resets under the action of the first elastic element 310. Thus, the connecting shaft 300 can be disengaged from the receiving cavity 221, thereby completing the disassembly of the pressing block device.

[0049] It is understandable that the first mating surface 414 and the second mating surface 331 can be set as a plane, an arc surface, etc., and no limitation is made here.

[0050] Reference Figures 6 to 7 In some embodiments, an anti-disengagement structure is provided between the limiting member 320 and the buckle 410. The anti-disengagement structure is used to prevent the buckle 410 from disengaging from the slot 420 when the connecting shaft 300 is pulled upward in the assembly state of the pressing device, so as to prevent the connecting shaft 300 from being pulled out of the receiving cavity 221, thereby keeping the pressing device in a stable assembly state and ensuring the normal operation of the photovoltaic module.

[0051] Specifically, refer to Figures 6 to 7In some embodiments, the anti-disengagement structure includes a third mating surface 321 provided on the limiting member 320. The third mating surface 321 is located on the side close to the movable member 330. In this embodiment, the third mating surface 321 is set as a plane, and the included angle between the third mating surface 321 and the connecting shaft 300 is not greater than 90°. When the connecting shaft 300 is pulled upward, the third mating surface 321 abuts against the buckle 410, and the limiting member 320 cannot cause the buckle 410 to retract into the mounting cavity 222, thereby preventing the connecting shaft 300 from being pulled out of the receiving cavity 221.

[0052] Reference Figures 1 to 4 In some embodiments, both the first pressing block 110 and the second pressing block 120 facing the installation space 150 are provided with wear-resistant inserts 160, which are used to abut against the photovoltaic panels of the photovoltaic module. The wear-resistant inserts 160 can improve the wear resistance of the pressing block assembly 100 and adapt to high-frequency disassembly and assembly scenarios.

[0053] In some embodiments, the wear-resistant insert 160 for contacting the photovoltaic panel has a ceramic coating on its surface, and a buffer layer is provided on the ceramic coating. The buffer layer can be made of a flexible material such as silicone. By providing the buffer layer, the pressure distribution of the photovoltaic panel at the pressing device can be made uniform, the surface stress of the photovoltaic panel can be reduced, thereby optimizing the pressure distribution of the clamping surface of the pressing assembly 100 and avoiding damage to the photovoltaic assembly.

[0054] Reference Figures 1 to 4 To facilitate the assembly of the wear-resistant insert 160, the surfaces of the first pressure block 110 and the second pressure block 120 facing the installation space 150 are provided with dovetail grooves 140. The side of the wear-resistant insert 160 away from the photovoltaic panel is configured to fit the dovetail groove 140. During assembly, the wear-resistant insert 160 can be directly inserted into the corresponding dovetail groove 140, which is convenient for assembly.

[0055] Reference Figures 1 to 5 The surface of the buffer layer has a plurality of spaced protrusions 161, and the protrusions 161 are provided with clamping surfaces for contacting the photovoltaic panel. In some embodiments, the clamping surfaces can be set as arc surfaces. By combining the buffer layer and the arc-shaped contact surfaces, the pressure distribution of the clamping surfaces of the pressure block assembly 100 can be further optimized to avoid damage to the photovoltaic module.

[0056] It is understandable that the clamping surface can also be set to a plane, and this is not limited here.

[0057] Reference Figures 1 to 4 In some embodiments, both the first pressing block 110 and the second pressing block 120 are provided with weight reduction grooves 130. The weight reduction grooves 130 can reduce the weight of the pressing block assembly 100, which can save materials, reduce costs, and reduce the strength during assembly.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
