Description

Technical Field

[0001] This utility model relates to the field of street light technology, and in particular to a die-cast aluminum shell structure for street lights. Background Technology

[0002] As an important component of urban infrastructure, modern streetlights utilize LED bulbs to ensure energy efficiency, and the application of IoT technology enables intelligent management. This has resulted in significant improvements in energy efficiency and environmental friendliness for streetlights.

[0003] Streetlight housings are typically made of die-cast aluminum, but existing housing structures often have the following drawbacks: 1. Due to an unreasonable structural design, the center of gravity of the streetlight is biased towards the front, requiring the support rod to have higher structural strength, thus increasing costs; 2. The installation connection design between the housing and the cover is not reasonable, resulting in an overall thickness that is not compact enough, leaving room for improvement; furthermore, the sealing design between the housing and the cover is not reliable; 3. The structural design of the lamp mounting head is not reasonable, resulting in insufficient strength and a risk of breakage.

[0004] Therefore, how to provide a street light die-cast aluminum shell structure with a more reasonable shell design that allows the center of gravity of the lamp to be shifted backward, the lamp layout to be more compact, the sealing effect to be better, and the structural strength to be higher has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is how to provide a street light die-cast aluminum shell structure with a more reasonable shell design that can shift the center of gravity of the lamp to the rear, make the lamp layout more compact, improve the sealing effect, and increase the structural strength.

[0006] To achieve the above objectives, this utility model provides a street light die-cast aluminum shell structure, including a shell, which includes a shell cover with an overall flat rectangular box structure and an open lower side. A shell cover plate is installed on the open side of the shell cover via a mounting and fixing structure. The rear end of the bottom surface of the shell cover is drawn upward to form a protruding box for installing the drive circuit structure. The feature is that a horizontally extending mounting plate is connected to the middle of the rear end surface of the shell cover, and each mounting plate has a mounting and fixing hole at a corner position above the mounting plate. Multiple support bars are arranged at intervals along the length of the shell cover above the mounting plate, and each has an arc-shaped mounting notch at the middle of its upper side. A counterweight is integrally formed at the rear end of the upper surface of the shell cover, opposite to the mounting notch, and the inner side of the counterweight is connected to the outer side of the protruding box. The lighting fixture support rod for mounting the lighting fixture can pass through the mounting notch in sequence and abut against the outer end face of the counterweight.

[0007] Thus, the aforementioned die-cast aluminum shell structure for the streetlight, by incorporating a counterweight, shifts the center of gravity of the entire streetlight backward, resulting in a more rational center of gravity design. This enhances stability after installation and ensures more reasonable stress distribution on the support rod, reducing installation costs. Furthermore, the mounting plate, support strip, mounting notch, and mounting holes facilitate easier installation of the light fixture, while the counterweight also serves to limit the movement of the support rod.

[0008] As an optimization, mounting posts are provided at the four corner positions above the mounting plate, and mounting fixing holes are provided on the mounting posts.

[0009] In this way, by setting up mounting columns, it is easier to arrange the mounting and fixing holes.

[0010] As an optimization, two longitudinally arranged reinforcing ridges are provided on each side of the upper surface of the mounting plate; and the mounting post is provided between the two ends of the pair of reinforcing ridges.

[0011] In this way, by setting up reinforcing ridges, the structural strength of the mounting plate is improved, and the risk of breakage is better avoided; and the structural strength of the mounting column is also increased.

[0012] Furthermore, the inner end of the reinforcing ridge extends inward and is connected to the outer side of the protruding box.

[0013] Furthermore, each side of the mounting column is connected to the inner side of a pair of reinforcing ridges.

[0014] Furthermore, the upper end face of the mounting column is located above the upper surface of the reinforcing ridge.

[0015] Furthermore, the lower surface of the mounting plate protrudes downwards as a whole, so that the lower surface of the mounting plate is located below the lower surface of the housing.

[0016] Furthermore, the shell, counterweight, mounting plate, support strip, mounting column, and reinforcing ridge are integrally formed.

[0017] As an optimization, multiple heat dissipation ribs are provided on the upper surface of the casing, arranged longitudinally and spaced apart laterally.

[0018] In this way, by setting up heat dissipation fins, heat dissipation can be achieved, and the structural strength of the casing can also be improved.

[0019] Furthermore, multiple longitudinally spaced, V-shaped raised strips are provided on the upper surface of the shell.

[0020] As an optimization, the housing cover includes a rear cover plate corresponding to the protruding cover position; it also includes a front light-transmitting plate, the lower surface of the light-transmitting plate being pulled inward at a position opposite to the internal lamp plate of the housing, so that mounting cavities and protrusions are formed on the lower surface and inner surface of the light-transmitting plate respectively; a protruding lens with an overall elliptical design is provided on the bottom surface of the mounting cavity at a position opposite to the lamp beads on the lamp plate; rectangular holes are provided on the protrusions corresponding to the lamp beads on the lamp plate, and circular cavities are provided on the bottom surface of the rectangular holes.

[0021] In this way, the structural design of the cover plate is simpler and more reasonable; it also allows the LED beads on the internal light panel to better match the light-transmitting plate; and it makes the arrangement in the thickness direction more compact, reducing the overall thickness.

[0022] As an optimization, the four edges of the shell cover are bent upwards to form a flange. A mounting ring protrudes horizontally outwards from the center of the outer circumference of the flange. A mounting groove is provided on the upper surface of the mounting ring for mounting a sealing ring, and the upper and lower surfaces of the sealing ring are respectively supported in the mounting groove and on the lower surface of the shell cover. A support ring is provided on the upper surface of the outer circumference of the mounting ring, and the outer side of the support ring is bent downwards to form a ring-shaped retaining edge. The mounting and fixing structure includes a plurality of fixing posts protruding from the lower surface of the support ring and arranged at intervals along the outer contour of the shell cover. Screw holes are provided on the fixing posts for arranging connecting screws, and the connecting screws can be correspondingly connected to the threaded connection holes of the shell cover.

[0023] This design makes the cover plate simpler and more reasonable, allowing it to be better installed and fixed on the open side of the cover, resulting in a more stable and reliable installation and a better sealing effect.

[0024] Furthermore, the screw hole includes a large-diameter section at the lower end and a small-diameter section at the upper end, such that the diameter of the large-diameter section matches the head of the connecting screw.

[0025] As an optimization, a protruding post is provided on the upper surface of the housing at a position corresponding to the fixing post, and the upper end of the threaded connection hole extends through the wall thickness of the housing and extends to the inner end of the protruding post.

[0026] In this way, by setting a protruding post, the axial dimension of the threaded connection hole can be made larger, maximizing the axial dimension of the threaded connection hole without increasing the thickness of the housing, thereby improving the stability of installation.

[0027] As an optimization, the open side of the shell is bent outward horizontally, and then bent upward and vertically in sequence to form a reinforced flange.

[0028] In this way, by setting up reinforced flanges, the structural strength of the open side of the shell can be improved.

[0029] In summary, the aforementioned die-cast aluminum housing structure for streetlights, through the design of counterweights, makes the housing design more rational, allowing the center of gravity of the lamp to be shifted backward. The design of the housing cover plate makes the lamp layout more compact and the sealing effect better. The design of the mounting plate section makes the lamp mounting structure stronger.

[0043] like Figures 1 to 12 As shown, a street light die-cast aluminum shell structure includes a shell, which includes a shell cover 1 with an overall flat rectangular box structure and an open bottom. A shell cover plate 2 is installed on the open side of the shell cover and fixed by a mounting structure. The bottom surface of the shell cover is drawn upward at the middle of the rear end to form a protruding box 3 for mounting the drive circuit structure. A horizontally extending mounting support plate 4 is also connected to the middle of the rear end face of the shell cover. Each of the mounting support plates has a mounting hole 5 at a corner position above the mounting support plate. Multiple support bars 6 are arranged at intervals along the length of the shell cover above the mounting support plate, and each of them has an arc-shaped mounting notch 7 at the middle of its upper side. A counterweight block 8 is integrally formed at the rear end of the upper surface of the shell cover and opposite to the mounting notch. The inner side of the counterweight block is connected to the outer side of the protruding box. The lighting fixture support rod for mounting the lighting fixture can pass through the mounting notch in sequence and abut against the outer end face of the counterweight block.

[0044] Thus, the aforementioned die-cast aluminum shell structure for the streetlight, by incorporating a counterweight, shifts the center of gravity of the entire streetlight backward, resulting in a more rational center of gravity design. This enhances stability after installation and ensures more reasonable stress distribution on the support rod, reducing installation costs. Furthermore, the mounting plate, support strip, mounting notch, and mounting holes facilitate easier installation of the light fixture, while the counterweight also serves to limit the movement of the support rod.

[0045] In this specific embodiment, a mounting post 9 is provided at each of the four corner positions above the mounting support plate, and the mounting post is provided with the mounting fixing hole.

[0046] In this way, by setting up mounting columns, it is easier to arrange the mounting and fixing holes.

[0047] In this specific embodiment, two longitudinally arranged reinforcing ridges 10 are provided on each side of the upper surface of the mounting bracket; and the mounting post is provided between the two ends of the pair of reinforcing ridges.

[0048] In this way, by setting up reinforcing ridges, the structural strength of the mounting plate is improved, and the risk of breakage is better avoided; and the structural strength of the mounting column is also increased.

[0049] Furthermore, the inner end of the reinforcing ridge extends inward and is connected to the outer side of the protruding box.

[0050] Furthermore, each side of the mounting column is connected to the inner side of a pair of reinforcing ridges.

[0051] Furthermore, the upper end face of the mounting column is located above the upper surface of the reinforcing ridge.

[0052] Furthermore, the lower surface of the mounting plate protrudes downwards as a whole, so that the lower surface of the mounting plate is located below the lower surface of the housing.

[0053] Furthermore, the shell, counterweight, mounting plate, support strip, mounting column, and reinforcing ridge are integrally formed.

[0054] In this specific embodiment, a plurality of heat dissipation ribs 11 are arranged longitudinally and spaced apart laterally on the upper surface of the housing.

[0055] In this way, by setting up heat dissipation fins, heat dissipation can be achieved, and the structural strength of the casing can also be improved.

[0056] Furthermore, multiple longitudinally spaced, V-shaped raised strips 12 are provided on the upper surface of the shell.

[0057] In this specific embodiment, the housing cover includes a cover plate 13 at the rear end and corresponding to the protruding cover position; it also includes a light-transmitting plate 14 at the front end, the lower surface of the light-transmitting plate being pulled inward at a position opposite to the lamp plate inside the housing, so that mounting recesses 15 and protrusions 16 are respectively formed on the lower surface and inner surface of the light-transmitting plate; a protruding lens 17 with an overall elliptical design is provided on the bottom surface of the mounting recess at a position opposite to the lamp beads on the lamp plate; rectangular holes 18 are provided on the protrusions corresponding to the lamp beads on the lamp plate, and circular recesses 19 are provided on the bottom surface of the rectangular holes.

[0058] In this way, the structural design of the cover plate is simpler and more reasonable; it also allows the LED beads on the internal light panel to better match the light-transmitting plate; and it makes the arrangement in the thickness direction more compact, reducing the overall thickness.

[0059] In this specific embodiment, the four periphery of the shell cover plate is bent upward to form a flange 20. A mounting ring 21 is formed by horizontally protruding outward at the middle of the outer periphery of the flange. A mounting groove is provided on the upper surface of the mounting ring for mounting a sealing ring 22, and the upper and lower surfaces of the sealing ring are respectively supported in the mounting groove and on the lower surface of the shell cover. A support ring 23 is provided on the upper side of the outer periphery of the mounting ring, and the outer side of the support ring is bent downward to form a ring-shaped retaining edge 24. The mounting and fixing structure includes a plurality of fixing posts 25 protruding from the lower surface of the support ring and arranged at intervals along the outer contour of the shell cover. Screw holes are provided on the fixing posts for arranging connecting screws, and the connecting screws can be correspondingly connected to the threaded connection holes of the shell cover.

[0060] This design makes the cover plate simpler and more reasonable, allowing it to be better installed and fixed on the open side of the cover, resulting in a more stable and reliable installation and a better sealing effect.

[0061] Furthermore, the screw hole includes a large-diameter section at the lower end and a small-diameter section at the upper end, such that the diameter of the large-diameter section matches the head of the connecting screw.

[0062] In this specific embodiment, a protruding post 26 is provided on the upper surface of the housing at a position corresponding to the fixing post, and the upper end of the threaded connection hole extends through the wall thickness direction of the housing and extends to the inner end of the protruding post.

[0063] In this way, by setting a protruding post, the axial dimension of the threaded connection hole can be made larger, maximizing the axial dimension of the threaded connection hole without increasing the thickness of the housing, thereby improving the stability of installation.

[0064] In this specific embodiment, after the open side of the shell is bent outward horizontally, it is then bent upward and outward in sequence to form a reinforcing flange 27.

[0065] In this way, by setting up reinforced flanges, the structural strength of the open side of the shell can be improved.

[0066] In summary, the aforementioned die-cast aluminum housing structure for streetlights, through the design of counterweights, makes the housing design more rational, allowing the center of gravity of the lamp to be shifted backward. The design of the housing cover plate makes the lamp layout more compact and the sealing effect better. The design of the mounting plate section makes the lamp mounting structure stronger.
