Description

Technical Field

[0001] The utility model relates to the field of traffic safety equipment, in particular to an underground solar luminous road stud with a compression-resistant composite plastic shell structure. Technical Background

[0002] Underground solar luminous road studs are sometimes called solar raised road signs or solar ground lights. Most of them are road studs that combine a transparent plastic shell with a metal protective shell. When installed, the main part below the underground reference surface is buried in the road surface, and the top surface above the underground reference surface is exposed and flush with the road surface or slightly higher than the road surface. It has the function of storing solar energy during the day and supplying solar energy to the light-emitting device at night. It can play a visual induction or prompting role for motor vehicle drivers and pedestrians, and can also serve as auxiliary road lighting equipment.

[0003] However, the existing underground solar luminous road studs still have the following structural defects:

[0004] Although the compressive performance of the road studs is improved compared with the raised road studs and the road studs with transparent plastic shells due to the support and protection of the metal protective shell, in order to increase the area of ​​the solar photovoltaic panel excited by sunlight, increase the power generation of the solar photovoltaic device, prolong the luminous time or increase the luminous brightness or supply power for other functions, the top shell part adopts a large area of ​​transparent plastic shell structure and is suspended. Therefore, it is still easy to be crushed by overweight and overloaded vehicles, causing the top to sink, resulting in damage to the solar photovoltaic panel and other internal components, or leakage due to structural deformation, affecting the service life and failure rate of the product.

[0005] Therefore, the compressive performance of existing buried road spikes needs to be further improved;

[0006] If a metal protection structure is provided above the transparent plastic shell structure, it can further enhance its compressive strength, prolong its service life and reduce its failure rate. However, the metal protection structure will reduce the area of ​​the solar photovoltaic panel that is stimulated by sunlight, affect its power generation, and block the outward emission of the light-emitting device in its light-emitting inner shell.

[0007] Moreover, the metal protective shell of the existing buried solar luminous road studs is made of metal materials, mostly aluminum alloy or stainless steel, and the material cost is high;

[0008] Some people have tried to remove the metal protective shell and use transparent plastic shell road studs on open roads. However, due to the material limitations, the compressive strength of transparent plastic shell road studs is obviously insufficient and it is difficult to withstand vehicle rolling. Otherwise, the top of the road stud will sink, causing damage to its solar photovoltaic panels and other internal components, or cause water leakage due to structural deformation, affecting the service life and failure rate of the product. Therefore, it can only be used in special occasions such as greenways and parks, and the scope of use is very limited.

[0009] As the demand for intelligent road studs increases, their power consumption will increase, and larger solar photovoltaic panels will inevitably need to be installed to match larger power storage capacity to adapt to their working hours, which will inevitably increase the volume of their transparent plastic shells and increase the risk of structural deformation or cracking.

[0010] In summary, how to increase the compression resistance and waterproof performance of underground solar luminous road studs has become a difficult problem to be solved urgently in the industry. Utility Model Content

[0011] In view of the shortcomings of existing products, the technical problem to be solved by the utility model is to provide an underground solar luminous road stud with a compression-resistant composite plastic shell structure.

[0012] The utility model innovates the shell structure of the underground solar-powered reflective road stud:

[0013] In particular, through the innovative design of the inner cavity structure of the plastic shell, an internal vertical structural support body of the inner cavity structure is added, and the bottom of the transparent plastic shell is combined with a hot-melt composite bottom shell through a hot-melt composite process to form a hot-melt composite plastic shell structure with higher structural strength; the glue is poured back through the glue injection holes at the bottom and leveled and cured to combine the transparent surrounding walls of the transparent plastic shell, the vertical structural support body, the hot-melt composite bottom shell and the encapsulation glue cured molded body to form a waterproof and encapsulated pressure-resistant composite plastic shell structure.

[0014] This structure can improve the structural strength of the transparent shell and further enhance its compressive strength. In particular, it can be arranged at the periphery of solar photovoltaic panels and light-emitting devices to serve as a supporting structure, which can focus on protecting solar photovoltaic panels and light-emitting devices, reduce the damage to solar photovoltaic panels and other internal components caused by the top sinking due to vehicle running over, and its external structure can be flexibly designed as needed.

[0015] This structure improves the composite strength of the hot-melt composite plastic shell structure, making the overall structural strength of the composite shell higher, the top shell or the bottom shell is not easy to loosen or separate, and the encapsulation glue solidified body is not easy to crack or debond, further improving its overall waterproof performance and reducing the failure rate.

[0016] The utility model can not only further improve the structural strength and waterproof performance of the existing metal shell road studs, especially the compression resistance and waterproof performance of the buried solar luminous road studs with a large area of ​​solar photovoltaic panels, so that they can withstand the rolling of heavy-loaded vehicles, thereby reducing their failure rate and extending their service life;

[0017] Moreover, the fully plastic road spikes can replace similar metal road spikes to a certain extent and be used on lower-grade roads or roads with few heavy-loaded vehicles, thereby effectively reducing material costs;

[0018] Even a simplified version of the road stud with a luminous inner structure similar to a plastic shell can be directly used to further reduce costs.
