Description

Technical Field

[0001] This utility model belongs to the field of solar energy technology, specifically relating to solar lighting, and more particularly to solar panel brackets and lighting devices. Background Technology

[0002] With the widespread application of renewable energy, photovoltaic streetlights are becoming increasingly popular as a green lighting solution; their core component, photovoltaic panels, are usually fixed to the streetlight poles through a support system to achieve stable energy harvesting and structural support.

[0003] In existing technologies, the fixing of brackets and photovoltaic panels mainly relies on mechanical connection methods, among which bolt tightening is the most common fixing method. However, the bolt tightening process is highly dependent on the experience and operating force of the construction personnel. Workers find it difficult to accurately judge the degree of tightening, and the phenomenon of "over-tightening" is very easy to occur.

[0004] Excessive tightening can cause plastic deformation of the photovoltaic panel frame (usually made of aluminum alloy or lightweight alloy). This deformation not only damages the structural integrity of the panel edge, but may also cause local stress concentration, especially at the stress nodes where the frame contacts the support. Under strong winds, the deformed panel is prone to microcrack propagation due to stress release or fatigue effects, eventually leading to cracking or even breakage.

[0005] Therefore, how to avoid over-tightening bolts during assembly is a technical problem that urgently needs to be solved in this field.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0007] This disclosure provides at least one embodiment of a solar panel bracket to solve the technical problem of excessive bolt tightening during assembly.

[0008] In a first aspect, embodiments of this disclosure provide a solar panel bracket, comprising: a pair of transverse brackets and a plurality of longitudinal reinforcing brackets, the longitudinal reinforcing brackets being equally spaced between the two transverse brackets, one of the longitudinal reinforcing brackets being fitted with a connector for fixing a lighting device; a padding structure disposed at the edge of a threaded hole in the transverse bracket; and a locking structure adapted to pass through the threaded hole to fix the frame of the solar panel onto the transverse bracket; wherein the locking end of the locking structure is adapted to pass through the threaded hole or even inside the frame, and the pressing surface of the locking structure abuts against the padding structure.

[0009] In one alternative embodiment, the padding structure includes an isolation member, and a buffer pad that abuts against the locking structure is embedded on the pressing surface of the isolation member.

[0010] In one optional embodiment, the isolation member includes a buffer platform, which is fixed to the edge of the threaded hole of the transverse bracket; and a V-shaped annular groove is formed on the circumferential surface of the buffer platform, and a limiting annular groove is formed on the pressing surface of the buffer platform.

[0011] In one optional embodiment, the buffer pad includes a T-shaped elastic pad, the narrow side of which is embedded in the limiting ring groove, the wide side of which abuts against the pressing surface, and a plurality of anti-slip grooves are provided on the exposed end face of the T-shaped elastic pad.

[0012] In one alternative embodiment, the locking structure includes a bolt and a nut disposed at one end of the bolt, the bolt being adapted to pass through the buffer platform or even the frame, and one end of the nut being adapted to abut against the exposed end face of the T-shaped elastic pad.

[0013] Secondly, some embodiments also provide a lighting device, including: a street lamp support pole and a lamp body and a battery panel bracket fixed on the street lamp support pole; the battery panel bracket is connected to the frame of the battery panel by a locking structure.

[0014] In one optional embodiment, the solar panel support includes: a pair of transverse brackets and a plurality of longitudinal reinforcing brackets, the longitudinal reinforcing brackets being equally spaced between the two transverse brackets, one of the longitudinal reinforcing brackets having a connector for fixing to a lighting device mounted on it; a padding structure disposed at the edge of a threaded hole in the transverse bracket; and a locking structure adapted to pass through the threaded hole to fix the frame of the solar panel to the transverse bracket; wherein the locking end of the locking structure is adapted to pass through the threaded hole or even inside the frame, and the pressing surface of the locking structure abuts against the padding structure.

[0015] In one alternative embodiment, the padding structure includes an isolation member, and a buffer pad that abuts against the locking structure is embedded on the pressing surface of the isolation member.

[0016] In one optional embodiment, the isolation member includes a buffer platform, which is fixed to the edge of the threaded hole of the transverse bracket; and a V-shaped annular groove is formed on the circumferential surface of the buffer platform, and a limiting annular groove is formed on the pressing surface of the buffer platform; the buffer pad includes a T-shaped elastic pad, the narrow side of the T-shaped elastic pad is embedded in the limiting annular groove, the wide side of the T-shaped elastic pad abuts against the pressing surface, and a plurality of anti-slip grooves are provided on the exposed end face of the T-shaped elastic pad.

[0017] In one alternative embodiment, the locking structure includes a bolt and a nut disposed at one end of the bolt, the bolt being adapted to pass through the buffer platform or even the frame, and one end of the nut being adapted to abut against the exposed end face of the T-shaped elastic pad.

[0018] The beneficial effects of this utility model are that it provides a battery panel bracket, which provides a padding structure at the mounting threaded hole position of the horizontal bracket. This allows the locking structure to have a buffering effect when connecting the horizontal bracket and the battery panel frame. When the tightening force is large, the padding structure can release the tightening pressure by deforming itself, thereby preventing the horizontal bracket connected to the battery frame from deforming. This effectively solves the problem of frame deformation or even breakage caused by over-tightening, and enhances the stability of the bracket.

[0039] Research has revealed the following drawbacks of existing technologies: the fixing of the bracket and the photovoltaic panel mainly relies on mechanical connection methods, among which bolt tightening is the most common fixing method. However, the bolt tightening process is highly dependent on the experience and operating force of the construction personnel. Workers find it difficult to accurately judge the degree of tightening, and "over-tightening" is very likely to occur.

[0040] Excessive tightening can cause plastic deformation of the photovoltaic panel frame (usually made of aluminum alloy or lightweight alloy). This deformation not only damages the structural integrity of the panel edge, but may also cause local stress concentration, especially at the stress nodes where the frame contacts the support. Under strong winds, the deformed panel is prone to microcrack propagation due to stress release or fatigue effects, eventually leading to cracking or even breakage.

[0041] Therefore, how to avoid over-tightening bolts during assembly is a technical problem that urgently needs to be solved in this field.

[0042] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.

[0043] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0044] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0045] like Figures 1 to 4As shown, some embodiments provide a solar panel bracket, including: a pair of horizontal brackets 1 and a plurality of vertical reinforcing brackets 2, the vertical reinforcing brackets 2 being installed at equal intervals between the two horizontal brackets 1, and a connector 3 for fixing to a lighting device being installed on one of the vertical reinforcing brackets 2; the horizontal brackets 1, the vertical reinforcing brackets 2 and the connector 3 are all made of the same material, wherein the connector 3 is used to install the bracket as a whole on the pole of the street light, wherein one side of the horizontal brackets 1 and the vertical reinforcing brackets 2 is used to abut against the solar panel 4 and the frame 5, and the horizontal brackets 1 and the frame 5 are fixedly connected.

[0046] Specifically, to prevent deformation of the frame 5 due to excessive connection progress, a shim structure 7 and a locking structure 6 are provided at the edge of the threaded hole of the transverse bracket 1. The shim structure 7 is suitable for passing through the threaded hole to fix the frame 5 of the battery panel 4 to the transverse bracket 1. The locking end of the locking structure 6 is adapted to pass through the threaded hole or even inside the frame 5. The pressing surface 713 of the locking structure 6 abuts against the shim structure 7. The locking structure 6 includes a bolt 61 and a nut 62 set at one end of the bolt 61. The bolt 61 is suitable for passing through the buffer platform 711 or even inside the frame 5 (inside the threaded hole corresponding to the frame 5). One end of the nut 62 is suitable for abutting against the exposed end face of the T-shaped elastic pad 721. The shim structure 7 not only raises the mounting surface of the locking structure 6, but also prevents the plane of the transverse bracket 1 from directly contacting the nut 62. When the tightening force is too large, the shim structure 7 will deform with the tightening force. At this time, the contact surface between the transverse bracket 1 and the frame 5 is still a plane.

[0047] The following describes the composition of the padding structure 7. The padding structure 7 includes an isolating member 71, which is made of the same material as the transverse bracket 1. The isolating member 71 is fixed to the transverse bracket 1. A buffer pad 72 that abuts against the locking structure 6 is embedded on the pressing surface 713 of the isolating member 71. The isolating member 71 includes a buffer platform 711, which is fixed to the edge of the threaded hole of the transverse bracket 1. A V-shaped annular groove 712 is formed on the circumferential surface of the buffer platform 711. The V-shaped annular groove 712 allows the buffer platform 711 to release the tightening force by reducing its angle (i.e., deformation) when subjected to a certain compressive force, so that the overall deformation of the buffer platform 711 remains consistent during deformation. In addition, a limiting annular groove 714 is formed on the pressing surface 713 of the buffer platform 711. The buffer pad 72 includes a T-shaped elastic pad 721. The narrow side of the T-shaped elastic pad 721 is embedded in the limiting ring groove 714, and the wide side of the T-shaped elastic pad 721 abuts against the pressing surface 713. Multiple anti-slip grooves 722 are provided on the exposed end face of the T-shaped elastic pad 721. The T-shaped elastic pad 721 is designed to prevent the nut 62 from retracting and to provide a buffering effect.

[0048] Some embodiments also provide a lighting device, including: a street lamp support pole and a lamp body and a battery panel 4 bracket fixed on the street lamp support pole; the battery panel 4 bracket is connected to the frame 5 of the battery panel 4 via a locking structure 6. The battery panel 4 bracket includes: a pair of transverse brackets 1 and a plurality of longitudinal reinforcing brackets 2, the longitudinal reinforcing brackets 2 being equally spaced between the two transverse brackets 1, one of the longitudinal reinforcing brackets 2 being equipped with a connector 3 fixed to the lighting device; a padding structure 7, which is disposed at the edge of the threaded hole of the transverse bracket 1; a locking structure 6, which is adapted to pass through the threaded hole to fix the frame 5 of the battery panel 4 to the transverse bracket 1; wherein, the locking end of the locking structure 6 is adapted to pass through the threaded hole or even inside the frame 5, and the pressing surface 713 of the locking structure 6 abuts against the padding structure 7.

[0049] The padding structure 7 includes an isolating member 71, and a buffer pad 72 that abuts against the locking structure 6 is embedded on the pressing surface 713 of the isolating member 71. The isolating member 71 includes a buffer platform 711, which is fixed to the edge of the threaded hole of the transverse bracket 1; and a V-shaped annular groove 712 is formed on the circumferential surface of the buffer platform 711, and a limiting annular groove 714 is formed on the pressing surface 713 of the buffer platform 711; the buffer pad 72 includes a T-shaped elastic pad 721, the narrow side of the T-shaped elastic pad 721 is embedded in the limiting annular groove 714, the wide side of the T-shaped elastic pad 721 abuts against the pressing surface 713, and a plurality of anti-slip grooves 722 are provided on the exposed end face of the T-shaped elastic pad 721.

[0050] The locking structure 6 includes a bolt 61 and a nut 62 disposed at one end of the bolt 61. The bolt 61 is adapted to pass through the buffer platform 711 or even inside the frame 5. One end of the nut 62 is adapted to abut against the exposed end face of the T-shaped elastic pad 721.

[0051] In summary, by setting a padding structure 7 at the mounting threaded hole position of the transverse bracket 1, the locking structure 6 has a buffering effect when connecting the transverse bracket 1 and the frame 5 of the battery panel 4. When the tightening force is large, the deformation of the V-shaped annular groove 712 and the compression of the T-shaped elastic pad 721 can release the tightening pressure, thereby preventing the transverse bracket 1 connected to the frame 5 of the battery panel 4 from deforming. This effectively solves the problem of excessive tightening causing deformation or even breakage of the frame 5, and enhances the stability of the bracket.
