Description

Technical Field

[0001] This application relates to the field of cable installation technology, and in particular to a flexible cable hook and a photovoltaic system. Background Technology

[0002] A photovoltaic (PV) power generation system is a power generation system that uses the photovoltaic effect of photovoltaic cells to directly convert solar radiation energy into electrical energy. Its basic components generally include a photovoltaic module array. A box is welded to the back of the photovoltaic module at the lead wire to connect the cables so that the battery can be connected to other devices or between batteries. During the process of laying the cables between the photovoltaic module array, hooks and wire clips are generally needed to achieve relative fixation between the cables and the photovoltaic modules to improve the stability of the cable laying.

[0003] However, the inventors believe that the aforementioned technologies have the following drawbacks: the commonly used method of fixing cables is to combine plastic or other materials with the frame of a single photovoltaic module, and then use the plastic clips to fix the cables around the frame of the photovoltaic module. However, plastic clips are troublesome to install, are prone to aging and damage, and the method of fixing cables is relatively limited. Summary of the Invention

[0006] A flexible cable hook includes a hook portion and an abutment portion, the hook portion and the abutment portion being adapted to be connected and fixed to two spaced-apart frame sides respectively, a cable placement area being formed between the hook portion and the abutment portion, the cable placement area being located in the gap between the two frame sides, at least a portion of the cable placement area extending out of the gap and located outside at least one frame side.

[0007] In some embodiments, the frame has a top surface and a bottom surface, the hook portion engages with the top surface of the first frame, and at least a portion of the cable placement area protrudes from the bottom surface of the first frame and the bottom surface of the second frame, and is adapted to accommodate at least one cable.

[0008] In some embodiments, the upper end of the hook portion is provided with a folded corner portion, which is adapted to be hung on the top surface of the first frame.

[0009] In some embodiments, the cable placement area is provided with a first cable channel in a first direction, and the cable placement area is provided with a second cable channel in a second direction, wherein the first cable channel and the second cable channel are adapted to accommodate cables.

[0010] In some embodiments, the cable placement area has a passage plane. In a plane parallel to the bottom surface of the frame, the angle between the passage plane and the first cable channel is α, the angle between the passage plane and the second cable channel is β, and the angle between the first cable channel and the second cable channel is γ, where α + β = γ.

[0011] In some embodiments, the abutment portion is an elastomer, and the abutment portion and the hook portion are interference-fitted within the gap. The abutment portion is adapted to restrict the movement of the cable placement area along the width direction of the gap, and the hook portion is adapted to restrict the movement of the cable placement area along the height direction of the gap.

[0012] In some embodiments, an elastic reinforcing portion is provided between the abutting portion and the cable placement area. The elastic reinforcing portion is adapted to move the abutting portion away from the hook portion. The abutting portion is adapted to restrict the movement of the cable placement area along the width direction of the gap, and the hook portion is adapted to restrict the movement of the cable placement area along the height direction of the gap.

[0013] In some embodiments, the contact distance x between the abutment portion and the hook portion and the frame in the width direction of the gap is greater than the width of the gap, the outer diameter distance y of the cable placement area in the width direction of the gap is less than the width of the gap, and the inner diameter distance z of the cable placement area in the width direction of the gap is greater than the diameter of the cable.

[0014] In some embodiments, the abutting portion has a limiting segment within the abutting surface with the frame, the abutting portion is adapted to contact the frame in a third direction, and the limiting segment is adapted to contact the frame in a fourth direction.

[0015] In some embodiments, the limiting segment is perpendicular to the height direction of the gap; one or more limiting grooves are provided on the frame, and the limiting segment is adapted to engage with one or more of the limiting grooves to restrict the movement of the abutment portion along the height direction of the gap.

[0016] In some embodiments, the elastic cable hook is formed by bending a filament, the hook portion is the middle part of the filament, and the abutment portion and the cable placement area are symmetrically arranged on both sides of the hook portion.

[0018] Compared with related technologies, one or more embodiments of this application include at least one of the following beneficial technical effects:

[0019] (1) The elastic cable hook of this application is easy to produce, has high transportation space utilization, and can effectively reduce transportation and inventory costs. It can be easily disassembled and assembled between two frames using the hook part and the abutment part. The disassembly and assembly are relatively easy, and the hook is not easily damaged during the disassembly and assembly process. After the cable is installed on the hook, it can be stabilized under the joint gravity of the two, so that the cable is not easy to shake and fall off.

[0020] (2) The elastic cable hook of this application optimizes the relative position between the cable placement area and the frame, so that the cable placement area is appropriately lower than the bottom surface of the frame. This not only facilitates the cable laying and reduces structural interference with the frame during the laying process, but also keeps the cable as straight as possible after the laying is completed, reducing the degree of bending of the cable, thereby protecting the cable and improving the stability of the cable.

[0021] (3) The flexible cable hook of this application optimizes the structure of the cable placement area, which can accommodate and fix cables in multiple directions, making the cable arrangement more diverse, more versatile, and able to enrich application scenarios. Attached Figure Description

[0037] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing specific embodiments only and is not intended to limit this application; the terms "comprising," "including," "having," "containing," etc., in the description, claims, and accompanying drawings of this application are open-ended terms. Therefore, "comprising," "including," or "having" refers to, for example, a method or apparatus having one or more steps or elements, but is not limited to having only these one or more elements.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0038] In the description of this application, it should be understood that the terms "center", "lateral", "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application 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. Therefore, they should not be construed as limitations on this application.

[0039] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

[0040] In this application, the term "implementation" means that a specific feature, structure, or characteristic described in connection with an implementation can be included in at least one implementation of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same implementation, nor is it a separate or alternative implementation mutually exclusive with other implementations. Those skilled in the art will understand, explicitly and implicitly, that the implementations described in this application can be combined with other implementations.

[0041] As mentioned above, it should be emphasized that when the term "comprising / including" is used in this specification, it is used to explicitly indicate the presence of the stated feature, integer, step, or component, but does not exclude the presence or addition of one or more other features, integers, steps, components, or groups of features, integers, steps, or components. As used in this application, the singular forms "a," "an," and "the" also include the plural forms, unless the context clearly indicates otherwise.

[0042] One or more embodiments of this application disclose a flexible cable hook, see reference Figures 1 to 12 The device includes a hook portion 31 and an abutment portion 32, which are adapted to be connected and fixed to two spaced-apart frame 1 respectively. A cable placement area 33 is formed between the hook portion 31 and the abutment portion 32. The cable placement area 33 can accommodate and fix the cable 4, so that the cable 4 is close to the frame 1, which can limit the cable 4 from falling to the ground, reduce the bending of the cable 4, and reduce the length of cable 4 required to connect the photovoltaic modules, thereby reducing costs. At the same time, the cable 4 is fixed under the joint action of the hook 3 and the frame 1, which can obtain higher deployment stability, is not easily blown by the wind, and ensures the normal operation of the photovoltaic modules.

[0043] The cable placement area 33 is located in the gap 2 between the two frame 1s. It can use the gap 2 between the two frame 1s to fix the hook part 31 and the abutment part 32 and reduce the structural interference between the cable placement area 33 and the photovoltaic module. At least part of the cable placement area 33 extends out of the gap 2 and is located outside at least one frame 1. It can effectively reduce the installation difficulty of the cable 4, make it convenient for installers to put the cable 4 into the cable placement area 33, and also make it convenient to observe the connection between the cable 4 and the cable placement area 33.

[0044] Since the height of the gap 2 between the two frame 1 is determined by the plane containing the upper surface of the frame 1 and the plane containing the lower surface of the frame 1, at least a portion of the cable placement area 33 extends out of the gap 2 and is located outside at least one frame 1. This means that at least a portion of the cable placement area 33 extends out of the gap 2 and protrudes from the plane containing the upper (lower) surface of at least one frame 1. It can also be understood that at least a portion of the cable placement area 33 extends to the outside of the gap 2. At this time, the frame 1 is on the protruding side of the cable placement area 33, and the existence of the cable placement area 33 can be observed even along the direction in the plane containing the upper (lower) surface of the frame 1.

[0045] like Figure 2In the illustrated embodiment, the frame 1 has a top surface 11 and a bottom surface 12. The hook portion 31 engages with the top surface 11 of the first frame 13. At least a portion of the cable placement area 33 protrudes from the bottom surface 12 of the first frame 13 and the bottom surface 12 of the second frame 14, and is adapted to accommodate at least one cable 4. This embodiment helps to fix the cable 4 to the lower side of the frame 1, so that the cable 4 can be hidden under the frame 1, thereby allowing the cable 4 to be protected by the frame 1 and the photovoltaic unit installed on the frame 1, improving the safety and stability of the cable 4.

[0046] like Figure 3 In the illustrated embodiment, the frame 1 has a top surface 11 and a bottom surface 12. The hook portion 31 engages with the top surface 11 of the first frame 13. At least a portion of the cable placement area 33 protrudes from the top surface 11 of the first frame 13 and the top surface 11 of the second frame 14, and is adapted to accommodate at least one cable 4. This embodiment can help fix the cable 4 to the upper side of the frame 1, facilitate the laying of the cable 4, effectively reduce the difficulty of fixing the cable 4, and improve the fixing efficiency of the cable 4.

[0047] like Figure 1 In the embodiment shown, the upper end of the hook portion 31 is provided with a bend portion 311, which is suitable for hanging on the top surface 11 of the first frame 13. The hook 3 can be installed on the top surface 11 of the first frame 13 by gravity through the bend portion 311, which is convenient and efficient for installation.

[0048] like Figures 2 to 3 In the embodiment shown, the surface shape of the inner corner side of the folded portion 311 is set to fit the top surface 11 of the first frame 13, which can improve the connection stability between the folded portion 311 and the top surface 11 of the first frame 13, thereby reducing the movement of the hook 3 and improving the installation stability of the hook 3.

[0049] The cable placement area 33 has a first cable channel 331 in the third direction and a second cable channel 332 in the length direction of the gap 2. The first cable channel 331 and the second cable channel 332 are suitable for accommodating the cable 4. By setting cable channels in multiple directions in the cable placement area 33, the hook 3 can obtain multiple cable 4 laying directions, improve versatility and applicability, increase application scenarios, and eliminate the need to make hooks 3 of different specifications for different directions, thus reducing costs.

[0050] like Figures 4 to 8 In the embodiment shown, the first direction is the width direction of the gap 2, and the first cable channel 331 can accommodate the cable 4 passing through the width direction of the gap 2. The second direction is the length direction of the gap 2, and the second cable channel 332 can accommodate the cable 4 passing through the length direction of the gap 2.

[0051] It is understandable that by designing the width and height of the first cable channel 331 and the second cable channel 332, the first cable channel 331 and the second cable channel 332 can accommodate one or more cables 4.

[0052] like Figures 7 to 8 In the embodiment shown, the cable placement area 33 has a passage plane 333, through which the first cable channel 331 and the second cable channel 332 both pass. In a plane parallel to the bottom surface 12 of the frame 1, the angle between the passage plane 333 and the first cable channel 331 is α, the angle between the passage plane 333 and the second cable channel 332 is β, and the angle between the first cable channel 331 and the second cable channel 332 is γ, where α + β = γ. The cable placement area 33 has only one passage plane 333, which can simultaneously form the first cable channel 331 and the second cable channel 332. This effectively reduces the structural complexity of the cable placement area 33, improves the structural compactness, and thus reduces production and processing costs.

[0053] In some embodiments, the first cable channel 331 can accommodate the cable 4 passing through the width direction of the gap 2, and the second cable channel 332 can accommodate the cable 4 passing through the length direction of the gap 2. The angle between the passage plane 333 and the first cable channel 331 and the second cable channel 332 is 45°, which ensures the structural support while realizing the bidirectional cable 4 function.

[0054] In some embodiments, the cable placement area 33 has two passage planes 333, through which the first cable channel 331 and the second cable channel 332 pass respectively. By changing the structure of the hook 3, the passage planes 333 in the cable placement area 33 can be changed, thereby enabling changes in the shape and position of the first cable channel 331 and the second cable channel 332.

[0055] Similarly, if you want to increase the number of cable channels, you can optimize the structure of the cable placement area 33 and increase the number of passage planes 333 to accommodate and fix the cable 4 in more directions.

[0056] When the cable placement area 33 is formed by filaments, the passage plane 333 can be formed by filaments surrounding a plane without enclosing the top of the passage plane 333. This allows the cable 4 to be inserted from the top of the cable placement area 33 into the first cable channel 331 and the second cable channel 332 within the passage plane 333, thereby reducing the difficulty of laying the cable 4.

[0057] In some embodiments, the abutment portion 32 is an elastic body, and the abutment portion 32 and the hook portion 31 are interference-fitted within the gap 2. The abutment portion 32 is adapted to restrict the movement of the cable placement area 33 along the width direction of the gap 2, and the hook portion 31 is adapted to restrict the movement of the cable placement area 33 along the height direction of the gap 2. The abutment portion 32 can cooperate with the hook portion 31 in abutting manner to play a role in structural stability within the gap 2. The assembly and disassembly are simple, convenient and efficient, without the need for tools or fasteners for fixation.

[0058] In some embodiments, an elastic reinforcing part 34 is provided between the abutting part 32 and the cable placement area 33. The elastic reinforcing part 34 is adapted to move the abutting part 32 away from the hook part 31. The abutting part 32 is adapted to restrict the movement of the cable placement area 33 along the width direction of the gap 2. Under the action of gravity, especially after the cable 4 is installed, the hook part 31 is adapted to restrict the movement of the cable placement area 33 along the height direction of the gap 2. By adding the elastic reinforcing part 34, the fixing effect of the hook 3 between the two frame 1 can be improved, the stability can be improved, and the probability of the hook 3 coming off can be reduced.

[0059] like Figure 2 In the embodiment shown, the elastic reinforcing part 34 can be a bent structure, which enables the abutting part 32 to move away from the hook part 31 more strongly, while not easily interfering with the installation of the cable 4, and has low manufacturing difficulty.

[0060] like Figure 10 In the embodiment shown, the elastic reinforcement 34 can be a torsion spring structure, which enables the abutment portion 32 to move more away from the hook portion 31, thereby improving the interference fit effect between the two frame 1 and improving installation stability.

[0061] like Figure 2 In the embodiment shown, the contact distance x between the abutment portion 32 and the hook portion 31 and the frame 1 in the width direction of the gap 2 is greater than the width of the gap 2, the outer diameter distance y of the cable placement area 33 in the width direction of the gap 2 is less than the width of the gap 2, and the inner diameter distance z of the cable placement area 33 in the width direction of the gap 2 is greater than the diameter of the cable 4.

[0062] In some embodiments, the contact distance x between the abutment portion 32 and the hook portion 31 and the frame 1 in the width direction of the gap 2 is 1.4 times the width of the gap 2, which makes the installation of the hook 3 more stable and also makes it less likely to increase the difficulty of disassembly.

[0063] In some embodiments, the outer diameter y of the cable placement area 33 in the width direction of the gap 2 is slightly smaller than the width of the gap 2, which reduces the probability of structural interference between the cable placement area 33 and the gap 2 during the installation of the hook 3 and improves the smoothness of disassembly and assembly.

[0064] In some embodiments, the inner diameter distance z of the cable placement area 33 in the width direction of the gap 2 is slightly larger than the diameter of the cable 4, which can reduce the difficulty of accommodating the cable 4, but also makes it less likely for the cable 4 to become loose.

[0065] It is understandable that, given that the outer diameter distance y of the cable placement area 33 in the width direction of the gap 2 and the inner diameter distance z of the cable placement area 33 in the width direction of the gap 2 are determined, the outer diameter length of the cable placement area 33 in the passage plane 333 can be calculated as y / cosα, and the included angle α can be determined by combining the inner diameter distance z of the cable placement area 33 in the width direction of the gap 2 with the inner diameter distance of the cable placement area 33 in the length direction of the gap 2.

[0066] like Figure 11 In the embodiment shown, the abutting part 32 is provided with a limiting segment 321 in the abutting surface with the frame 1. The abutting part 32 is adapted to contact the frame 1 in a third direction, and the limiting segment 321 is adapted to contact the frame 1 in a fourth direction. The limiting segment 321 can increase the contact area between the abutting part 32 and the frame 1. At the same time, the contact direction of the limiting segment 321 and the abutting part 32 is different, which can enable the hook 3 and the frame 1 to obtain a large friction force in all directions, thereby improving the installation stability.

[0067] like Figure 12 In the embodiment shown, the limiting segment 321 is perpendicular to the height direction of the gap 2, thereby increasing the friction between the abutting part 32 and the frame 1 in the height direction of the gap 2, so as to restrict the movement of one side of the abutting part 32 of the hook 3 along the height direction of the gap 2.

[0068] like Figure 12 In the embodiment shown, one or more limiting grooves 15 are provided on the frame 1. The limiting segment 321 is adapted to be fitted and connected with one or more limiting grooves 15 to restrict the movement of the abutment 32 along the height direction of the gap 2. The limiting groove 15 can further improve the limiting effect of the limiting segment 321 and improve the installation stability of the hook 3.

[0069] like Figure 12 In the embodiment shown, the limiting groove 15 is at least formed on the second frame 14.

[0070] like Figures 1 to 6 In the embodiments shown in 10 to 12, the elastic cable hook 3 is formed by bending a filament, the hook portion 31 is the middle part of the filament, and the abutment portion 32 and the cable placement area 33 are arranged on both sides of the hook portion 31.

[0071] like Figure 3In the embodiment shown, the abutment portion 32 and the cable placement area 33 are symmetrically arranged on both sides of the hook portion 31, and the two cable placement areas 33 are arranged in a way that is inclined away from the hook portion 31 in the length direction of the gap 2. This can make the hook 3 have higher structural stability and reduce the probability of the hook 3 moving within the gap 2.

[0072] like Figure 9 In the embodiment shown, the abutment portion 32 and the cable placement area 33 are arranged on both sides of the hook portion 31. The cable placement areas 33 on both sides of the hook portion 31 can be arranged in a way that tilts to the same side, which can reduce the space occupied in the length direction of the gap 2 and make the overall structure of the hook 3 more compact.

[0073] In some embodiments, the filament can be made of different materials according to actual needs and manufactured into different specifications and sizes through different processes. Common materials include metal materials such as aluminum alloy and stainless steel. Metal materials can effectively slow down the aging of hook 3 and reduce the risk of failure. When stainless steel is used, outdoor corrosion protection and service life can be achieved. Common manufacturing processes include roll forming process, extrusion forming process, etc., and the common thickness is 1mm to 3mm.
