Abstract
Description
A type of cushioned, pressure-resistant, raised reflective road stud Technical Field
[0001] This utility model relates to the field of traffic safety equipment, specifically to a buffer-resistant, pressure-resistant protruding reflective road stud. Background Technology
[0002] Raised reflective road studs, also known as raised road studs, are mainly installed on both sides of the road or on the center line of the road. Their main body protrudes from the road surface, and retroreflectors are installed on the front side of the main body to reflect the headlights of oncoming vehicles and provide road guidance for drivers.
[0003] Existing raised reflective road studs mostly use plastic for their shells and microprism-type retroreflectors (reflective lattice plates) or microbead array composite type retroreflectors (glass beads) for their retroreflectors. These are fixed in the grooves on the road stud's facing surface with adhesive or by ultrasonic heat fusion. Due to the limitations of the shell material, the overall compressive strength of the road stud is insufficient, making it easy for it to break or for the retroreflectors to fall off or be damaged due to wheel impact and crushing. As a result, the road stud cannot perform its reflective function.
[0004] To address this, some have opted for metal road stud housings to increase the overall structural strength of the road studs. However, due to the significant difference in properties between the bottom material of the retroreflector and the road stud housing, the bonding strength between the retroreflector and the road stud housing is insufficient. This makes it easy for the retroreflector to detach or be damaged due to impact and crushing by vehicle wheels, rendering the road studs unusable.
[0005] Others use lens unit retroreflectors with a spherical lens structure at the head and a reflective coating on the lower part or bottom, which meet the conditions for retroreflection. These are implanted into cylindrical holes in plastic road stud shells and fixed with adhesive. While these retroreflectors are less likely to fall off or be damaged by wheel impacts, the shell material limits their susceptibility to breakage under pressure. Furthermore, the lack of a protective structure for the lens unit retroreflector makes it susceptible to wear and tear from wheel impacts, reducing its reflective performance or even causing it to shatter.
[0006] In conclusion, how to provide a protruding reflective road stud that is not easily detached or damaged and has good overall pressure and impact resistance has become an urgent problem to be solved in the industry. Summary of the Invention
[0007] In view of the shortcomings of existing products, the technical problem to be solved by the present invention is to provide a protruding reflective road stud whose retroreflector is not easy to fall off or be damaged, and which has good overall pressure and impact resistance.
[0008] This utility model uses a metal (stainless steel or aluminum alloy) casting shell to increase the overall structural strength of the road stud. The shape of the shell can be designed as needed. It also uses a lens unit type retroreflector with a cylindrical body, a spherical optical lens structure at the top, a crown-like shape at the bottom, and a reflective coating on the part of the body near the bottom and the bottom, which meets the conditions for retroreflection. The retroreflector is inserted into the cylindrical hole of the plastic road stud shell and fixed with adhesive, so that the retroreflector is not easily detached or damaged by the impact and crushing of the wheel.
[0009] Specifically, an extended base plate extends outward from the bottom of the front (rear) side of the road stud by a certain distance. Between the extended base plate and the side of the road stud (the part between the cylindrical holes on the side of the road stud shell used to install the retroreflector), a ramp body is set, starting from the extended base plate and rising from the outside to the inside, connecting with the corresponding side of the road stud, forming an outer low and inner high ramp body. Each ramp body can be combined and set up with the same or different lengths, the same or different widths, and the same or different heights as needed. It can play a role in gentle slope transition, disperse the impact force of the tire on the side of the road stud, especially on its retroreflector, thereby withstanding vehicle rolling, reducing bumps, and making its retroreflector less prone to wear or even breakage due to wheel impact, ensuring the service life of the road stud, and the reflective performance of the road stud can also meet the standards.
[0010] The specific technical solution of this utility model is: a buffer-resistant and pressure-resistant protruding reflective road stud, comprising a road stud base (1) (preferably made of metal such as stainless steel die casting or aluminum alloy die casting, or reinforced composite material), a retroreflector (2), and an adhesive layer (3) (preferably acrylic, polyurethane, or epoxy). The retroreflector (2) is fixed to the road stud base (1) by the adhesive layer (3).
[0011] The main structure of the road stud base (1) (the part that protrudes above the road surface after installation) is similar to a platform structure with a large bottom (bottom surface) and a small top (top surface). The front side (1c-1) and / or rear side (1c-2) of the main structure of the road stud base (1) have multiple cylindrical receiving holes (1d) with outward openings on the sides. The retroreflector (2) is a retroreflector whose main body (2b) is cylindrical, whose top (head) (2a) has a spherical optical lens structure, whose bottom (2c) is similar to a spherical crown shape, and whose main body (2b) near the bottom (2c) and bottom (2c) are respectively coated with a reflective coating (2d) to meet the retroreflection conditions. The retroreflector (2) is implanted into the receiving hole (1d) and fixed by forming a structure through an adhesive layer (3).
[0012] The rail spike base (1) has an outwardly extending base plate (1b) below the receiving hole (1d). Between the extended base plate (1b) and the left and right sides (1c) of the main structure of the rail spike base (1), there is a ramp body (1p-1) that starts from the extended base plate (1b), rises from the outside to the inside, and connects with the left and right sides (1c) of the main structure of the rail spike base (1), forming a ramp body that is lower on the outside and higher on the inside. There is also a protruding rail spike base between the extended base plate (1b) and the adjacent receiving hole (1d). (1) The corresponding side (1c) of the main structure, starting from the outer base plate (1b), rises from the outside to the inside and connects with the adjacent receiving hole (1d) of the corresponding side (1c) of the main structure of the road stud base (1) to form a ramp body two (1p-2) that is lower on the outside and higher on the inside. [The left and right ramp bodies one (1p-1) plus ramp body two (1p-2) have at least three ramp bodies on one side, which can increase the structural strength of the overall shell, have a gentle slope transition function, effectively decompose the impact force of the wheel on the road stud, and reduce the bumps.]
[0013] Furthermore, the first ramp body (1p-1) is similar to a gentle slope structure with a wide bottom and a narrow top, or the second ramp body (1p-2) is similar to a reinforcing rib structure with a wide bottom and a narrow top (which serves to strengthen the structure and can withstand the crushing of heavy vehicles).
[0014] Alternatively, the slope surface of the first ramp body (1p-1) may be an inclined surface, a concave folded surface, or a concave curved surface, or the slope surface of the second ramp body (1p-2) may be an inclined surface, a concave folded surface, or a concave curved surface.

[0016] Furthermore, the track spike base (1) is provided with multiple ramp bodies (1p-2) protruding from the main structure of the track spike base (1) between the receiving holes (1d). These ramp bodies (1p-2) are generally an odd number, meaning at least one is located at the position of the central axis on the side of the track spike base (1). The central axes of the multiple ramp bodies (1p-2) are parallel to each other.
[0017] Alternatively, the ramp body one (1p-1) and ramp body two (1p-2) of the front side (1c-1) of the rail spike base (1) may be arranged at equal intervals on the left and right, or / and the ramp body one (1p-1) and ramp body two (1p-2) of the rear side (1c-2) of the rail spike base (1) may be arranged at equal intervals on the left and right.

The main body of the retroreflector (120) is a cylinder with a diameter D of 10mm to 15mm, a spherical optical lens structure at its head (120a), and a crown-like shape at its bottom (120c). A retroreflector, which meets the retroreflection conditions, has an aluminum-plated reflective layer (120d) coated on the main body (120b) near the bottom (120c) and the bottom (120c) respectively. It is implanted in a receiving hole (110d) and fixed by an adhesive layer (130) such as acrylic glue, polyurethane or epoxy glue. The retroreflector (120) has an incident angle θ3 between 20° and 45° in the vertical direction and an incident angle θ3 between 20° and 45° in the horizontal direction.
[0096] The rail spike base (110) has an extended base plate (110b) extending forward and backward by 8mm to 25mm at the part below the receiving hole (110d). The thickness of the extended base plate (110b) is between 2mm and 4mm. The extended base plate (110b) and the left and right sides (110c) of the main structure of the rail spike base (110) are respectively provided with a ramp that starts from the extended base plate (110b) and gradually rises from the outside to the inside in the front-back direction, and connects with the left and right sides (110c) of the main structure of the rail spike base (110), forming a ramp that is lower on the outside and higher on the inside. Body 1 (110p-1), and ramp body 2 (110p-2) with an outer lower and inner higher, wider and narrower inner slope, formed by the protruding side (110c) of the main structure of the rail spike base (110) and the corresponding accommodating hole (110d) of the outer extension base plate (110b) at intervals between the outer extension base plate (110b) and the adjacent accommodating hole (110d) of the corresponding side (110c) of the main structure of the rail spike base (110). Ramp body 2 (110p-2) is roughly spaced evenly on both sides, with the spacing slightly larger than the diameter of the accommodating hole (110d) it encloses. The slope surfaces of ramp body 1 (110p-1) and ramp body 2 (110p-2) are concave arc surfaces. The ratio of the height H to the length L of ramp body 1 (110p-1) is between 1:1 and 1:3, and the ratio of the height H to the length L of ramp body 2 (110p-2) is also between 1:1 and 1:3. Furthermore, the inclination of the slope surfaces of ramp body 1 (110p-1) and ramp body 2 (110p-2) is less than that of the track spike. The slope of the corresponding side of the main structure of the substrate (110), the slope of ramp body one (110p-1) and the slope of ramp body two (110p-2) are higher than the outer convex surface of the retroreflector (120) it encloses, which helps to protect the retroreflector (120) from the direct impact of the wheel. The open angle formed by the adjacent ramp body two (110p-2) and the center part of the retroreflector (120) in the accommodating hole (110d) it surrounds is greater than the incident angle θ4 of the retroreflector (120) in the horizontal direction, so as to ensure that the headlights are not blocked by the ramp body within a certain angle. The top surface of the main structure of the road stud base (110) is provided with a recessed, longitudinally extending strip groove (110t) with an extension length between 5mm and 15mm, corresponding to the location of the lower ramp body 2 (110p-2) or the location of the partition between the adjacent lower receiving holes (110d).

[0098] Furthermore, the (top view) shape of the spike base body (110) can also be wider on the left and narrower on the right (the positive and negative directions of the spike are set to the right) or narrower on the left and wider on the right (the positive and negative directions of the spike are set to the left), as shown in Figure 4, so as to provide a deflection angle (correspondingly deflected to the right or left) reflective function, and it is mainly installed on the curve.
[0099] Furthermore, the widths, the lengths in the front and back directions, and the inclination angles of the slopes of the first slope body (110p-1) and the second slope body (110p-2) on one side of the spike base body (110) can be the same or different, and the widths, the lengths in the front and back directions, and the inclination angles of the slopes of each second slope body (110p-2) can also be the same or different, as shown in Figure 5, and it can
[0100] There are respectively three second slope bodies (110p-2) symmetrically arranged about the central axis of the spike base body (110) between the front and back sides of the spike base body (110) and the outer extension bottom plate (110b). The length of the first slope body (110p-1) of the spike base body (110) in the front and back directions of the spike is equal to the length of the second slope body (110p- to the length of the second slope bodies (110p-2) in the front and back directions of the spike at the positions of the central axes on the same side of the front and back of the spike base body (110) and is greater than the lengths of the other second slope bodies (110p-2) in the front and back directions of the spike on the same side of the front and back of the spike base body (110), forming an arrangement where the left and right sides and the middle of the slope bodies at the front and back sides of the spike base body (110) are long and the rest are short.
[0101] Furthermore, the shape of the spike base body (110) can be set as required. As shown in Figure 6, the outer extension bottom plate (110b) below the accommodation hole (110d) can be concave, so that the main body looks like a Chinese character 'wang' in top view, to save material costs and reduce production costs. And there is a second slope body (110p-2) between the positions of the central axes of the front and back sides of the spike base body (110) and the outer extension bottom plate (110b). The length of the first slope body (110p-1) of the front and back sides of the spike base body (110) in the front and back directions of the spike is equal to the length of the second slope body (110p-2) on the same side of the front and back of the spike base body (110) in the front and back directions of the spike, forming an arrangement with equal lengths and equal intervals on the left, middle and right of the front and back sides of the spike base body (110).
